Acylated triterpene saponins from Silene jenisseensis.

From the roots of Silene jenisseensis a new trans-p-methoxycinnamoyl triterpene saponin has been isolated along with its cis-p-methoxycinnamoyl isomer as an inseparable mixture. Their structures were established by chemical means and spectroscopic methods including 1D- and 2D-homonuclear and heteronuclear correlation NMR spectroscopy as 3-O-[beta-D-galactopyranosyl-(1 --> 2)-beta-D-glucuronopyranosyl]-28-O-[beta-D-glucopyranosyl-(1 --> 2)-alpha-L-rhamnopyranosyl- (1 --> 2)-beta-D-4-O-trans-p-methoxycinnamoyl-fucopyranosyl] quillaic acid and its cis-isomer, respectively. They did not show any activity in the in vitro chemoluminescence granulocytes assay, but exhibited only a weak inhibitory effect in the cyclooxygenase inhibition assay.

[Video-assisted thoracic surgery: preliminary results of 25 cases].

From Oct 1992 to Dec 1993, 25 cases were done by VATS. They were: Wedge resection of the lung (5), biopsy of mediastinal mass (4), pleural biopsy (4), removal of mediastinal cyst (3), resection of pulmonary bullae and pleurodesis (2), removal of intrathoracic foreign body (2), lobectomy (2), removal of clotted blood of hemothorax (1), resection of malignant mesothelioma (1), and esophageal tumor (1). There was no severe complication. Three procedures of VATS needed to be converted to thoracotomy. All 25 patients were recovery well. The comment was done for indications and contraindications of VATS.

[Epidemiological survey on patients with advanced filariasis in Shandong Province with bancroftian filariasis basically eliminated].

This paper reports on the incidence of advanced filariasis after basic elimination of bancroftian filariasis since 1983 in Shandong Province. Investigation was carried out in a population of 166,776 between 1984 and 1988 in 252 villages of Teng Xian and other 5 counties/cities, the erstwhile highly endemic areas. A total of 1,038 filariasis patients were found with an average incidence of 0.6%. Among them, 383 were with elephantiasis, 357 with chyluria and 298 with hydrocele. 902 cases (86.9%) who suffered the disease before the elimination of filariasis and 136 cases (13.1%) after it, 125 (91.9%) being chyluria cases. The oldest of the 1,038 cases was 86 years of age and the youngest, 6 years of age. The course of duration as 8-74 years in elephantiasis cases, 82.8% of them (317 cases) had previously lymphangitis and/or lymphadenitis. In the past three years 16.4% (52 cases) suffered from prolonged or intermittent acute lymphangitis and/or lymphadenitis. The results of this survey indicated that, after the basic elimination of filariasis in Shandong Province together with thorough clearance of infection source, elephantiasis and hydrocele persisted while new cases of chyluria continued to develop. Therefore, in such areas more emphasis should be put on the treatment of clinical patients. New patients should be surveyed and old patients be treated actively so as to reach the goal of eradicating filariasis.

[Epidemiological surveillance of filariasis after its being basically eradicated in Shandong Province].

This paper reports the results of epidemiological surveillance in areas where filariasis has been basically eradicated and control measures no longer adopted in Shandong Province. A 3-year longitudinal surveillance in 18 villages in 5 counties and a cross-sectional survey in 13 villages of 4 counties were carried out. The results showed that the average microfilaria rate was further reduced from 0.28% and 0.15% in 1980 to 0.19% and 0.05% in 1986, decreased by 32.1% and 66.7% respectively. 34.2% of the microfilaremic cases were found to be negative during the two-year follow-up. The positive rate of IFA and skin test was 34.2% and 38.6% respectively. In longitudinal surveillance. of the 240,992 Culex pipiens pallens dissected, 152(0.06%) were found to harbour different stages of larvae, among them, 5 were infective larvae from 4 vector mosquitoes. In cross-sectional survey, of the 3,875 Culex pipiens pallens dissected only 1 which had bitten immigrant from Zhejiang was found to contain one larvae at stage 1. No positive mosquito was found in the household of native villagers. No new infection was discovered at longitudinal and cross-sectional survey. The transmission of filariasis in these areas was interrupted. The results showed that in areas where filariasis has been basically eradicated, further control measures may not be instituted, but the management population movement and surveillance should be strengthened.
