RESUMO
Most Mycobacterium tuberculosis (Mtb) resistant to rifampicin (RIF) has mutations in the rpoB gene, while most Mtb resistant to isoniazid (INH) has mutations in the katG gene or inhA promoter. We used gene chip technology to detect mutations in these genes to determine the resistance of Mtb to RIF and INH. A total of 4148 clinical specimens with sputum smear positivity for acid-fast bacilli (AFB) were detected. Then, taking the results of the drug sensitivity test (DST) as the reference standard, the detection efficiency of sputum samples from different grades of positive smears was compared in detail. We found that the sensitivity of the gene chip method for detecting sputum samples with a grade ≥ AFB 2 + was higher than that of sputum samples with a grade ≤ AFB 1 + (P < 0.05). When the grade of the sample was ≤ AFB 1 +, the sensitivity of the gene chip method was 72.6% for RIF, 67.3% for INH, and 60.0% for MDR-TB. When the grade of the sample was ≥ AFB 2 +, the sensitivity of the gene chip method was 84.5% for RIF, 78.2% for INH, and 73.9% for MDR-TB. The results show that gene chip technology can be directly used to diagnose drug-resistant tuberculosis in clinical specimens, and the diagnostic efficiency for the detection of sputum specimens with a grade ≥ AFB 2 + is better than that of other sputum specimens.

OBJECTIVE: Few double-blind controlled trials have been reported on Chinese patent medicines for the treatment of chronic prostatitis. The purpose of this study was to investigate the therapeutic efficacy of Qianlie Jiedu Capsule for chronic prostatitis (CP) by the randomized double-blind controlled method. METHODS: Eighty CP patients were equally randomized into an experimental and a control group, the former treated with Qianlie Jiedu Capsule + Rufloxacin, and the latter given placebo + Rufloxacin, both for 4 weeks. All the patients were evaluated by NIH-CPSI and EPS examination before and after the medication. RESULTS: After 4-week treatment, the total score of NIH-CPSI and the scores of pain, voiding symptoms and quality of life were significantly decreased in both groups compared with the baseline (P < 0.05), so did the leukocyte count in EPS (P < 0.05). And the experimental group showed significant drops in the above scores as compared with the control (P < 0.05), except in the leukocyte count in EPS (P > 0.05). CONCLUSION: Qianlie Jiedu Capsule combined with Rufloxacin is highly effective for CP by relieving pain and voiding symptoms,decreasing the leukocyte count in EPS and improving the life quality of the patients.

OBJECTIVE: To observe the effect of Chinese herbal medicine Qianggu drink ([Chinese characters: see text]) on bone histomorphometry of lumbar vertebrae in ovariectomized rats and to explore its mechanism. METHODS: Sixty female SD rats (weight 230 to 280 gram) were randomized into three groups: Qianggu drink ([Chinese characters: see text]) group (treatment group), Miacalcic group (control group) and blank group. The osteoporosis model was established successfully after all rats were ovariectomized for 10 weeks. The treatment group was used intragastric infusion with Qianggu drink ([Chinese characters: see text]) 0.001 ml/kg once a day. The control group was used hypodermic injection once a day with Miacalcic 0.72 U/kg. Five rats were killed respectively and the lumbar specimens were taken and cut for bone histomorphometric analysis at 45, 90, 135 and 180 days after the treatment. RESULTS: The thickness of trabecular bone in treatment group had the statistical significance with control group at 135 days after ovariectomized rats were given the medicine. The data of BV/TV and the thickness and space of trabecular bone had statistical significance compared with control group and blank group 180 days later. CONCLUSION: Qianggu drink ([Chinese characters: see text]) could effectively improve the histomorphometry indexes. The mechanism probably plays by stimulating osteogenesis and inhibiting the cytoactive of osteoclast and the trend of bone transform.
