[Detection of telomerase activity in bronchoscopic brush-off samples in patients with lung cancer].

Background And Objective: Recent studies have shown that activation of telomerase plays an important role in carcinogenesis. However, there was few report on the level of telomerase activity in small samples from the patients with lung cancer. This study was designed to investigate the diagnostic significance of the detection of telomerase activity in bronchoscopic brush-off cells from the patients with lung cancer.

Lack of correlation of vacA genotype, cagA gene of Helicobacter pylori and their expression products with various gastroduodenal diseases.

Objective: To investigate the correlation among vacA genotypes, cagA gene, VacA, serum CagA antibodies of Helicobacter pylori (H. pylori) and gastroduodenal diseases.

Methods: vacA genotypes and cagA gene of 62 H.

[The number of lymph node with metastases influences survival in patients with cancer of the thoracic esophagus].

Objective: To study the extent of lymph node involvement in relation to survival of patients with thoracic esophageal carcinoma.

Methods: From 1990 to 1993, there were 112 patients with thoracic esophageal carcinoma undergone esophagectomy through right thoracotomy and three-field lymphadenectomy. They were classified into three groups: group A, 44 patients without lymph node involvement; group B, 36 patients with 1 to 3 positive nodes; group C, 32 patients with > or = 4 involved lymph nodes.

[Effect of jian yan ling on serum lipids, apoprotein and lipoprotein-a].

Effect of Jian Yan Ling (JYL, mainly consisted of Succinum, Pteria margaritifers and Astragalus membranaceus etc.) on serum lipids was studied by double-blind method in 128 hyperlipemia patients. Patients were divided randomly into two groups, the test groups (64 cases) treated with JYL, while the other 64 cases treated with placebo as control for 3 months.

Effect of Astragalus membranaceus on electrophysiological activities of acute experimental Coxsackie B-3 viral myocarditis in mice.

A murine model for observing the effect of Astragalus membranaceus (AM) on electrophysiological action of the right ventricular myocardium was developed in 4-week-old male BALB/c mice infected with coxsackie B-3 virus (CB3V). The conventional microelectrode technique and a real-time data processor system were used. The survival rate in AM-treated mice was much higher and the percentage of abnormal action potential was much lower than those in infected control mice (P < 0.

[A lesson from abuse of antibiotics after open heart surgery].

This paper reports 8 cases of pseudomembranous colitis, 2 cases of fungal infection and 15 cases of drug fever, all of which were caused by persistent use of large doses of antibiotics following open heart surgery. The clinical characteristics of these complications and the methods of treating them are discussed, and the rational preventive use of antibiotics is emphasized.
