Coronary artery disease risk predicted by insulin resistance, plasma lipids, and hypertension in people without diabetes.

BACKGROUND: It has been shown that insulin resistance syndrome, including glucose intolerance, dyslipidemia, and hypertension, is frequently associated with coronary artery disease (CAD). However, their relative contributions and predictive power in the development of CAD are still unclear, particularly in persons without diabetes. METHOD: We examined these risk factors between 96 patients without diabetes but with angiographically documented CAD and 96 age-, sex-, and body mass index-matched healthy control subjects. Fasting plasma lipoprotein, glucose, and insulin concentrations in response to a 75-g oral glucose tolerance test were determined, and insulin sensitivity was measured by the insulin suppression test. RESULTS: Patients with CAD had significantly higher values of fasting glucose, glucose and insulin responses to oral glucose tolerance test, total cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride and decreased high-density lipoprotein (HDL) cholesterol concentrations compared with those of healthy people (P < 0.02-0.001). Although the steady-state plasma insulin values were similar in both groups, the steady-state plasma glucose (SSPG) concentrations were significantly higher in patients with CAD (12.2+/-0.4 versus 8.1+/-0.4 mmol/L, P < 0.001) compared with healthy subjects. When HDL < 0.9 mmol/L, LDL cholesterol > or = 4.1 mmol/L, triglyceride > or = 2.3 mmol/L, SSPG > or = 10.5 mmol/L, and presence of hypertension were defined as separate risk factors for CAD, significantly higher odds-ratio values were observed in patients with CAD compared with healthy people. From logistic multiple regression analysis, SSPG was the strongest risk, followed by lowered HDL cholesterol, elevated triglyceride and LDL cholesterol, and hypertension, to predict CAD. These 5 factors accounted for 36% of total risk for development of CAD in persons without diabetes. CONCLUSIONS: Patients without diabetes with CAD have abnormal glucose metabolism, hyperinsulinemia, and insulin resistance. Degree of insulin resistance (SSPG values), plasma lipid values, and history of hypertension together accounted for one third of all risk for CAD, although degree of insulin resistance was the strongest risk factor.

MIB-1 immunostaining is a beneficial adjunct test for accurate diagnosis of vulvar condyloma acuminatum.

The histopathologic diagnosis of vulvar condyloma acuminatum is often based on architectural features that are not specific for human papillomavirus (HPV) infection. Because HPV-associated lesions show increased cellular proliferation, the authors evaluated the usefulness of MIB-1 immunostaining as an aid in the differential diagnosis of cases equivocal for condyloma. The MIB-1 immunostaining pattern was correlated with HPV DNA detection in condyloma acuminatum (CON-A; n = 15), "consistent with condyloma" (c/w CON-A; n = 26), fibroepithelial polyp (FEP; n = 14), and squamous papilloma (n = 10). HPV was detected in 100% of the CON-A cases, and all cases demonstrated MIB-1-positive nuclei in the upper two thirds of the epithelial thickness. With this definition of MIB-1 positivity, there was complete concordance between MIB-1 positivity and HPV detection for all cases (kappa = 0.88). Of the cases c/w CON-A, 17 of 26 (65%) were positive for both MIB-1 and HPV, and could be reclassified as CON-A, whereas 35% were identified as an overdiagnosis based on negative results. In addition, two cases of FEP were MIB-1 and HPV positive, and thus were identified as an underdiagnosis. These results suggest significant overdiagnosis of cases equivocal for condyloma, and indicate that MIB-1 immunostaining is a beneficial adjunctive test when the morphologic features are suggestive but not diagnostic for CON-A.

Glucose-6-phosphatase mutation G188R confers an atypical glycogen storage disease type 1b phenotype.

Glycogen storage disease type 1a (GSD 1a) is caused by a deficiency in microsomal glucose-6-phosphatase (G6Pase). A variant (GSD 1b) is caused by a defect in the transport of glucose-6-phosphate (G6P) into the microsome and is associated with chronic neutropenia and neutrophil dysfunction. Mutually exclusive mutations in the G6Pase gene and the G6P transport gene establish GSD la and GSD 1b as independent molecular processes and are consistent with a multicomponent translocase catalytic model. A modified translocase/catalytic unit model based on biochemical data in a G6Pase knockout mouse has also been proposed for G6Pase catalysis. This model suggests coupling of G6Pase activity and G6P transport. A 5-mo-old girl with hypoglycemia, hepatomegaly, and lactic acidemia was diagnosed with GSD 1a. She also developed neutropenia, neutrophil dysfunction, and recurrent infections characteristic of GSD 1b. Homozygous G188R mutations of the G6Pase gene were identified, but no mutations in the G6P translocase gene were found. We have subsequently identified a sibling and two unrelated patients with similar genotypic/phenotypic characteristics. The unusual association of neutrophil abnormalities in patients with homozygous G188R mutations in the G6Pase gene supports a modified translocase/catalytic unit model.

Cell-based, high-content screen for receptor internalization, recycling and intracellular trafficking.

A variety of physiologically important receptors are internalized and then recycled back to the plasma membrane by the endocytic recycling compartment. These include the transferrin receptor and many G-protein coupled receptors (GPCRs). The internalization of GPCRs is a result of agonist stimulation. A cell-based fluorescent imaging assay is described that detects and quantifies the presence of fluorescently labeled receptors and macromolecules in the recycling compartment. This High Content Screening application is conducted on the ArrayScan II System that includes fluorescent reagents, imaging instrumentation and the informatics tools necessary to screen for compounds that affect receptor internalization, recycling and GPCR activation. We demonstrate the Receptor Internalization and Trafficking application by quantifying (i) the internalization and recycling of the transferrin receptor using a fluorescently labeled ligand and (ii) the internalization of a physiologically functional model GPCR, a GFP-parathyroid hormone receptor chimera. These assays give high signal-to-noise ratios, broad dynamic ranges between stimulated and unstimulated conditions and low variability across different screening runs. Thus, the Receptor Internalization and Trafficking application, in conjunction with the ArrayScan II System, forms the basis of a robust, information-rich and automated screen for GPCR activation.

Significantly higher levels of oxidized LDL autoantibody in coronary artery disease patients.

BACKGROUND: Increasing evidence shows that oxidized low-density lipoprotein (ox-LDL) might play an important role in the pathogenesis of atherosclerosis. Ox-LDL is immunogenic and induces an autoantibody, which we used as a tool for measuring the content of ox-LDL in vivo. METHODS: Patients who were admitted for diagnostic cardiac catheterization for typical or atypical angina pectoris were enrolled in this study. After fasting for 12 hours, a venous blood sample was drawn from the antecubital vein for testing triglyceride, total cholesterol, LDL cholesterol, high-density lipoprotein (HDL) cholesterol, and ox-LDL autoantibody. The ox-LDL autoantibody was quantified using an enzyme linked immunosorbent assay. All patients underwent coronary angiography. Those who had more than 50% angiographic coronary luminal stenosis, were grouped into the coronary artery disease (CAD) group. RESULTS: Sixty-four patients were enrolled in the study (male/female = 46/18; mean +/- standard deviation, age, 64 +/- 9 years). The CAD group had a significantly higher level of ox-LDL autoantibody than the non-CAD group (494.0 +/- 355.0 mU/ml vs 258.1 +/- 196.8 mU/ml, p = 0.004). However, the other lipid profiles including triglyceride, total cholesterol, LDL-cholesterol and HDL-cholesterol were not statistically different between the two groups. Forty-six patients in this study had an arterial blood sample taken from the femoral artery for testing ox-LDL autoantibody. There was no significant difference between the arterial and venous samples of ox-LDL autoantibody (385.2 +/- 333.3 mU/ml vs 399.3 +/- 339.5 mU/ml, n = 46, p = 0.530). CONCLUSIONS: Ox-LDL autoantibody was significantly higher in the CAD group. Ox-LDL may prove to play a key role in the pathogenesis of atherosclerosis. Further study of Ox-LDL and its role in the process of atherosclerosis is warranted.

Catheter-induced coronary spasm--a view of mechanical factors and experience with selective left coronary arteriography.

BACKGROUND: Coronary spasm during cardiac catheterization is not unusual. The mechanism of spasm remains uncertain, but is considered to be multifactorial. Many researchers believe that coronary spasm that develops during catheterization is partly spontaneous and partly catheter-induced. Because catheter-induced spasm results from mechanical irritation, we tried to find the iatrogenic factors that predispose patients to coronary spasm during coronary angiography. METHODS: Retrospectively, we reviewed the records of 7,295 patients who underwent coronary angiography at our hospital from June, 1983 to November, 1997; coronary spasm was documented in 30 patients, who became the study group. We randomly selected 41 patients who had normal coronary arteries as the normal control group. After reviewing cine films of coronary angiography, we compared these two groups for several parameters. These parameters included the length and diameter of the left main coronary artery (LMC), the angle between the LMC and the aorta, the angle between the catheter tip and the LMC, whether the catheter tip came into contact with the vascular wall and whether there was vessel wall bulging, catheter size and catheter/LMC ratio. This angiographic data and the demographic features, including age, sex, history of hypertension, diabetes mellitus, smoking, previous myocardial infarction, family history of coronary artery disease, cholesterol and triglyceride levels and chest pain character (exertional or rest pain) were compared between the study patient group and the control group. RESULTS: The results disclosed that larger catheter size (7.1 +/- 0.6 mm vs 6.4 +/- 0.7 mm, p < 0.001), smaller LMC diameter (4.2 +/- 0.9 mm vs 4.9 +/- 1.0 mm, p = 0.004), larger catheter/LMC ratio (0.07 +/- 0.05 vs 0.05 +/- 0.03, p = 0.022), catheter contact with the vessel wall (27/30 vs 20/41, p < 0.001) and vessel bulging (18/30 vs 5/41, p < 0.001) were related to catheter-induced coronary spasm. We found that the catheter tip coming into contact with the vessel wall, vessel wall bulging and catheter/LMC ratio (odds ratio 8.92 x 10(14)) were statistically significant factors predisposing patients to catheter-induced coronary spasm. CONCLUSIONS: Multiple factors contribute to coronary spasm. Of those, mechanical or iatrogenic factors might predispose patients to spasm during coronary catheterization. These facts deserve our attention, because iatrogenically induced spasms may be avoided by meticulously selecting catheters and manipulating them gently.

Autologous bone marrow transplantation for patients with acute myeloid leukaemia: prospective follow-up study.

OBJECTIVE: To study the use of autologous bone marrow transplantation to treat acute myeloid leukaemia when complete remission had been achieved and when no human leukocyte antigen matched related donor was available. DESIGN: Prospective follow-up study. SETTING: Government hospital, Hong Kong. PATIENTS: Eight patients (median age, 34 years [range, 16-45 years]) with acute myeloid leukaemia in whom complete remission had been achieved. INTERVENTION: Conditioning regimen of carmustine, amsacrine, etoposide VP-16, cytarabine, and infusion of unpurged marrow. MAIN OUTCOME MEASURES: Median time taken to reach neutrophil and platelet counts of > or =0.5 x 10(9) /L and > or = x 10(9) /L, respectively; mortality and relapse rates; and follow-up regimens used. RESULTS: Engraftment was successfully achieved in all patients and there were no early procedure-related mortalities. The median times required to reach a neutrophil count of > or =0.5 x 10(9) /L and a platelet count of > or =20 x 10(9) /L were 30 days (range, 18-36 days) and 38 days (range, 15-53 days), respectively. The median duration of hospital stay was 37 days (range, 25-43 days). Two patients died of a relapse of leukaemia at 6 and 9 months post-transplantation. Two patients experienced relapses: one at 8 months post-transplantation, for which conventional chemotherapy was restarted, and one at 18 months; treatment with all-trans-retinoic acid and conventional chemotherapy achieved a third complete remission in the latter patient, who had acute promyelocytic leukaemia. Continuous remission has been achieved in four of the eight patients after a median follow-up duration of 26 months (range, 6-43 months). CONCLUSION: Autologous bone marrow transplantation is an acceptable treatment for patients with acute myeloid leukaemia who lack a human leukocyte antigen-matched related donor.

Preservation of the thin distal urethra in hypospadias repair.

PURPOSE: We report our experience with preserving the thin distal urethra lacking corpus spongiosum for the treatment of hypospadias. MATERIALS AND METHODS: From January 1997 to October 1999 we treated primary hypospadias in 77 boys with a mean age of 4 years 10 months. After degloving the penile skin a segment of thin distal urethra lacking corpus spongiosum was noted in 18 patients (23.4%) with a mean age of 3 years 5 months. The thin distal urethra was preserved and incorporated as part of urethroplasty (group 1). The procedure was primarily completed by tubularized incised plate urethroplasty. We also performed tubularized incised plate urethroplasty in 31 boys (40.3%) with a mean age of 5 years 2 months who had normal coverage of the corpus spongiosum of a hypospadiac urethra (group 2). We compared the results of treatment in these 2 groups. The remaining 28 patients (36.4%) treated with other methods were excluded from study. RESULTS: In group 1 the distance from the original meatus to the urethra covered by healthy corpus spongiosum was 4 to 20 mm. (mean 8.2). If the thin distal urethra had been excised, the urethral meatus would have been relocated more proximal in these boys. Mean followup in groups 1 and 2 was 9.9 and 7.6 months, respectively. Postoperatively there were 2 (11.1%) urethrocutaneous fistulas in group 1 and 4 (12.9%) in group 2. Tubularized incised plate repair was successful in all 10 cases (100%) of distal hypospadias in group 2, and in 15 of 18 (83.3%) and 17 of 21 (81%) of proximal hypospadias cases in groups 1 and 2, respectively. There was no statistically significant difference in the success rate of hypospadias repair in the groups. CONCLUSIONS: We noted a significantly thin distal urethra in 23.4% of our cases of primary hypospadias. Mean length of the thin distal urethra was 8.2 mm. Preserving the thin distal urethra may simplify the operative procedure without compromising the surgical results of tubularized incised plate urethroplasty.

Randomized, double-blind comparison of irbesartan and enalapril for treatment of mild to moderate hypertension.

BACKGROUND: Irbesartan is a newly developed angiotensin II receptor antagonist. Its antihypertensive efficacy and safety in Taiwanese patients with mild to moderate hypertension remains to be determined. METHODS: This was a multicenter, double-blind, randomized, parallel group study. One hundred and sixteen patients from three centers were enrolled. After a placebo lead-in period of 14 days, 55 patients (24-75 years-of-age) who had a mean seated diastolic blood pressure of 95 to 110 mmHg were randomized to once-daily treatment with irbesartan 150 mg or enalapril 10 mg. Doses were doubled at week 4 if trough seated diastolic blood pressure was 90 mmHg or more. Trough blood pressure was measured at zero, two, four and eight weeks of treatment. RESULTS: Both treatments lowered blood pressure with no significant difference in efficacy between treatment groups. Irbesartan 150 mg to 300 mg provided reductions in trough seated systolic and diastolic blood pressures at week 8 of -16.5 mmHg and -7.2 mmHg, respectively, with 36% of patients having a favorable response. Similarly, enalapril 10 mg to 20 mg reduced systolic and diastolic blood pressure by -10.6 mmHg and -5.0 mmHg, respectively, with a response rate of 43%. Headache, malaise and dizziness were the major adverse reactions observed in both groups. The incidence of drug-related cough was significantly higher with enalapril (18%) than with irbesartan (0%). CONCLUSIONS: Irbesartan 150 mg to 300 mg once daily was as effective in lowering blood pressure as enalapril 10 mg to 20 mg once daily. Both irbesartan and enalapril were well tolerated, while there was a significantly lower incidence of cough with irbesartan compared with enalapril.

Associations between lipoprotein lipase gene polymorphisms and insulin resistance in coronary heart disease.

BACKGROUND: Lipoprotein lipase (LPL) is a crucial enzyme in plasma lipoprotein metabolism. Variants of the LPL gene (Pvu II and Hind III polymorphisms) may increase the risk of developing coronary heart disease (CHD) but their effect on insulin resistance remains unknown. The present study was conducted to examine whether DNA variations of the LPL gene were related to insulin resistance, carbohydrate and lipid risk factors for CHD in nondiabetic individuals. METHODS: Pvu II and Hind III allele status of the LPL gene and fasting plasma glucose, insulin and lipid values were determined in nondiabetic men with angiographically documented CHD (n = 102) and in a control group (n = 145). Plasma glucose and insulin responses to a 75-g oral glucose tolerance test and insulin resistance as measured by an insulin suppression test were also carried out in 46 (45%) of the patients with CHD and in 73 (50%) of the control individuals. RESULTS: The allele frequencies of LPL Pvu II and Hind III were not significantly different between the CHD patients and the controls. No association was found between Pvu II status and blood pressure, fasting plasma glucose, insulin, lipid levels or insulin resistance in patients with CHD. Nevertheless, compared with individuals with the Hind III H2H2 allele, CHD patients carrying the H1 allele (H1H1 + H1H2) were more insulin resistant, as indicated by higher steady state plasma glucose concentrations (253 +/- 87 vs 200 +/- 74 mg/dl, p = 0.032). CONCLUSIONS: We suggest that the LPL gene Hind III allele might be associated with insulin resistance in nondiabetic men with CHD. However, further studies with larger populations of both sexes will be required to confirm this finding.

[Studies on fermentation of decane 1,10-dicarboxylic acid(DC12)].

Candida tropicalis strain UH-2-48 can increase the production of decane 1,10-dicarboxylic acid(DC12) yield by 30% (from 81.7 g/L to 108.2 g/L) after regulating the fermentation condition. The purity of the DC12 is above 97%, which can meet the criteria of the succeeding synthesized industrial productions. Emulsifier can not only destroy the structure of the cell membrane in some degree, but also can enhance the permeability of the cell membrane. Furthermore, the structure of the emulsifier itself can also effect its function. Tween 60(0.10%) can enhance the production of DC12 tremendously. Urea, as the nitrogen resource, can affect the activity of cytochrome P450 enzyme. Some biochemistry and biophysics factors, such as penicillin, vitamin B2 and alanine, can increase the yield of DC12 during the process of fermentation. Ferment in 20 m3 fermentator, under the optimal condition, the average yield of DC12 using the strain HP-12 which derived from UH-2-48, is 202.1 g/L.

Prevalence of urinary incontinence and intention to seek treatment in the elderly.

BACKGROUND AND PURPOSE: Urinary incontinence (UI) is a common, distressing, and often disabling condition in the elderly. The objectives of this study were to estimate the prevalence and clinical characteristics of UI among elderly individuals living at home and to explore their perceptions of UI and intention to seek medical care. METHODS: A total of 504 elderly subjects aged 65 and older residing in Tungkang town (located in the southwestern part of Taiwan) were randomly sampled and surveyed face to face by registered nurses. The prevalence, clinical types, and perceptions of UI, and intention to seek treatment, were compared with chi-square statistics across various sociodemographic characteristics. Logistic regression analyses were conducted to identify factors associated with UI experience and intention to seek treatment. RESULTS: About 22% of respondents reported that they had experienced involuntary loss of urine in daily life. Women, people who were overweight, and those who were aged 70 years or older were at higher risk of UI. While women were more likely to suffer from stress incontinence, men were at higher risk of urge incontinence. Women, illiterate individuals, and those who perceived UI as a normal part of the aging process showed low intention to seek treatment for UI. CONCLUSIONS: The results of this study suggest that public awareness programs about UI and promotion of available treatment options are necessary to increase the intention to seek treatment among the elderly. Culturally sensitive programs should be designed, particularly for female and illiterate elderly, to provide incentives to seek medical care. The increasing availability of various treatment modalities coupled with education to correct commonly held misconceptions about UI might enable more elderly individuals to receive treatment for this common condition.

Synthesis, characterization and cytotoxicity of lanthanum(III) complexes with novel 1,10-phenanthroline-2,9-bis-alpha-amino acid conjugates.

Eight lanthanum(III) complexes with novel 1,10-phenanthroline-2,9-bis-alpha-amino acid conjugates were synthesized and characterized by elemental analyses, IR, MS, 1H-NMR, thermal analysis and conductance measurement. All lanthanum(III) complexes and the corresponding soluble ligand in water have been assayed for antitumor activity in vitro against HL-60 (human leukocytoma) cells, HCT-8 (human coloadenocarcinoma) cells, BGC-823 (human stomach carcinoma) cells, BeL-7402 (human liver carcinoma) cells and KB (human nasopharyngeal carcinoma) cells. The results show that several complexes have relative activity against different cell lines. In particular, the complexes La(L2) and La(L5) show relatively high activity against the BeL-7402 cell line. Moreover, they are slightly more effective than cisplatin. DNA binding studies indicate that the complex La(L2) possibly interacts with calf thymus DNA by both intercalative and covalent binding.

Cancer-testis antigens and ING1 tumor suppressor gene product are breast cancer antigens: characterization of tissue-specific ING1 transcripts and a homologue gene.

SEREX (serological analysis of recombinant tumor cDNA expression libraries) has been applied to several different tumor types and has led to the identification of a wide range of tumor antigens. In this study, a breast cancer library and a normal testicular library were analyzed using autologous and allogeneic breast cancer sera. Thirty genes were isolated, including 27 known genes and 3 previously unknown genes. Among the known genes, two cancer-testis (CT) antigens, NY-ESO-1 and SSX2, previously defined by SEREX analysis, were found. In addition, ING1, a candidate breast cancer suppressor gene, was isolated. This ING1 gene product was also recognized by 2 of 14 allogeneic sera from breast cancer patients but not 12 normal adult sera. Comparison of ING1 cDNA from normal and tumor tissues showed no mutation in the index breast cancer case and revealed the presence of at least three different mRNA transcripts with variable transcription initiation sites and exon usage. Tissue-specific expression of these transcripts was found in normal tissues and tumor cell line mRNAs. Furthermore, a novel gene, designated as ING2, sharing 76% nucleotide homology with ING1 was identified in the breast cancer cDNA library. The basis of the immunogenicity of ING1 and the biological role of ING1 and ING2 need further exploration.

Red wine inhibits monocyte chemotactic protein-1 expression and modestly reduces neointimal hyperplasia after balloon injury in cholesterol-Fed rabbits.

BACKGROUND: Wine consumption decreases the risk of myocardial infarction. Intimal hyperplasia contributes to restenosis after angioplasty. Local ethanol delivery inhibits intimal hyperplasia after balloon injury in rabbit iliac and pig coronary arteries. The effects of wine consumption on intimal response and monocyte chemotactic protein-1 (MCP-1) expression were studied in cholesterol-fed rabbits. METHODS AND RESULTS: Male rabbits were fed a 2% cholesterol diet together with red wine (12.5% vol, 5 mL/kg body wt per day; n=7), white wine (13.3% vol, 5 mL/kg body wt per day; n=7), or no wine as a control (n=8) for 6 weeks. A balloon injury of the abdominal aorta was performed at the end of the third week. Abdominal aortas were harvested at the end of 6 weeks. Neointimal hyperplasia was measured morphometrically. MCP-1 expression was determined by Northern blot, in situ hybridization, and immunohistochemistry. Rabbits fed red wine had significantly less neointimal hyperplasia than did control rabbits (intima/media area ratio 0.59+/-0.05 [red wine group] versus 0.79+/-0.07 [control group], P<0.05). However, rabbits fed white wine showed a trend (but not significant) toward less intimal response compared with control rabbits (intima/media area ratio 0.65+/-0.04 [white wine group] versus 0.79+/-0.07 [control group], P=0.165). Both red wine and white wine significantly reduced MCP-1 mRNA and protein expression in the aorta. CONCLUSIONS: Long-term consumption of red wine and white wine inhibits MCP-1 expression, and in the small number of animals studied, red wine modestly reduces neointimal hyperplasia. Since red wine exhibits higher antioxidant capacity than does white wine, the decreased intimal response might be partly attributed to its antioxidant effects.
