BACKGROUND: The length of postoperative drug therapy remains controversial in pulmonary tuberculosis. We analyzed our experiences to determine the postoperative duration of chemotherapy after resection. METHODS: A retrospective review was performed in 66 of 95 patients that underwent pulmonary resection for pulmonary tuberculosis between January 1993 and December 1998. We compared the relapse rates according to the length of postoperative chemotherapy in each group, classified by the results of sputum AFB culture before the surgery, the number of resistant durgs, the number of prior treatment and the division of anti-TB drugs used postoperatively. RESULTS: Fifty three of 66(80.3%) were men and 13(19.7%) were women with a median age of 33.5 years(range, 16 to 63). The mean lengths of the pre-and post-operative chemotherapies were 4.9 months, and 12.9 months respectively. Five of 66 patients(7.6%) relapsed during the mean period of follow up(39.7 months). In the group less than three times of the prior treatment, there were two relapses(20%) in Ed-the highlight above-rephrase 10 patients that were medicated for 6 months or less, and one relapse in 43 patients(2.3%) that took medicine for more than 6 months(p=0.03). In the group using second-line drugs postoperatively, there was one relapse(25%) in four patients that were medicated for 12 months or less. No patient in a total of 17 that received medicine for more than 12 months relapsed(p=0.03). CONCLUSION: We recommend that patients with the prior treatment less than three times should be treated for more than 6 months after resection and patients using the second-line drugs postoperatively should be medicated for more than 12 months.

Objective:To analyze risk factors for the rupture of basilar tip aneurysms (BTA) using morphological parameters assessed on CTA.Methods:The clinical data and CTA imaging characteristics of 62 patients with BTA from March 2016 to November 2020 in Huanhu Hospital of Tianjin were analyzed retrospectively. The patients were divided into un-rupture ( n=44) and rupture ( n=18) groups according to whether the BTA ruptured. The morphological parameters of aneurysms were measured and recorded. The number, shape and orientation of aneurysms were analyzed by χ 2 test between the two groups. The length (H max), height (H p), neck width (N D), aspect ratio (AR), size ratio (SR), angle of aneurysms (AA), flow angle (FA), basilar vessel angle (BVA), the angle between the proximal long axis of bilateral posterior cerebral artery P1 segment (P1-P1 angle), the angle between the proximal long axis of bilateral superior cerebellar arteries and bifurcation angle (the sum of the angle between the basilar artery and the bilateral posterior cerebral arteries) were analyzed by independent-sample t test between the two groups. On the basis of univariate analysis, logistic regression was used to identify the independent risk factors for BTA rupture. ROC curve analysis was further performed. Results:BTA with irregular shape was more likely to break (χ 2=5.412, P<0.05). The H max[(4.18±2.11)mm], N D [(3.06±1.75)mm], P1-P1 angle (148°±18°) in the rupture group were smaller than those in the un-rupture group [(6.38±2.21)mm, (5.20±1.59)mm, 178°±25°], with statistically significant difference ( P<0.05). While AR (1.19±0.13), BVA (82°±11°), and bifurcation angle (212°±18°) in the rupture group were larger than those in the un-rupture group (1.05±0.18, 70°±10°, 181°±27°), with statistically significant difference ( P<0.05). The logistic regression analysis showed that the shape of aneurysms (β=4.878, OR=11.418, P=0.019), BVA (β=0.165, OR=1.177, P=0.043), and P1-P1 angle (β=-0.223, OR=1.080, P=0.029) were independent risk factors for BTA rupture. The ROC curve analysis showed that the cut-off value of BVA and P1-P1 angle to predict the BTA rupture were 76.7° and 158.5°, and area under curve (AUC) were 0.79 and 0.86, respectively. The AUC of combined BVA with P1-P1 angle was 0.89. Conclusion:The shape of aneurysms, BVA and P1-P1 angle are independent risk factors for BTA rupture. BTA are prone to rupture when the shape of aneurysm is irregular, BVA>76.7 ° and P1-P1 angle<158.5 °.

Objective To observe the effects of Chinese herbal compounds (alkaloid of Coptidis Rhizoma 40%, total saponin of panax notoginseng 35%, and polysaccharide of Ophiopogonis Radix 25%) on levels of blood glucose, fructosamine, and insulin of diabetic rats, and explore mechanism of action.Methods Ten rats were randomly chosen as blank control group, and other rats were used to establish diabetic rat models by STZ intraperitoneal injection. Successfully molding rats were randomly divided into Chinese herbal compounds high, medium, low dose groups, metformin group, and model group, 10 rats in each group. Each rat received gavage for continuous 4 weeks. Then rat blood was collected by cutting head and taking caudal vein. FBG was detected by glucose oxidase method;insulin level was detected by radio-immunity double antibody method;fructosamine content was detected by fructosamine method.Results Compared with the blank control group, model group the levels of FBG, froctosamine content increased, while fasting insulin level were lower after 4 weeks'medication. Compared with the model group, the levels of FBG, froctosamine content in Chinese herbal compounds high and medium dose groups and metformin group were lower, while fasting insulin level increased after 4 weeks'medication (P<0.05).Conclusion TCM herbal compounds can increased the basic insulin level by decreasing the contents of FBG and fructosamine.

Objective: To study the effect of docetaxet (DOC) combined with 4-AP on human breast can-cer MCF-7 cells and to explore whether 4-AP could strengthen the effect of docetaxel. Methods: MTT assays were performed to investigate the effect of docetaxel, 4-AP and the combination of them on the proliferation of MCF-7 cells. Flow cytometry was employed to detect cell cycles and cell apoptosis after the cells were stained by PI alone or by Annexin-V and PI. Results: Docetaxel could significantly inhibit the proliferation of MCF-7 cells in a dose- and time- dependent manner. 4-AP could inhibit the proliferation of MCF-7 cells and the inhibitory rates were 11.9%±1.7%, 42.1%±3.2%, and 44.2%±1.6% at 24h, 48h and 72h after adding 4-AP. Moreover 4-AP (5mmol/L) could strengthen the effect of docetaxel. 4-AP (25μmol/L) could increase the effect of Docetaxel. Docetaxel at 5μmol/L could significantly increase the percentage of cells at G_2/M (53.58%± 1.44% vs. 8.83%±0.44%, P<0.01) and decrease the percentage of cells at G_0/G_1 (11.48%±0.14% vs. 63.89%±0.98%, P<0.01), indicating that docetaxel blocked MCF-7 cells at G_2/M phase. 4-AP at 5mmol/L could in-crease the percentage of MCF-7 cells at G_0/G_1 and decrease the percentage of cells at G_2/M (0.42%±0.17% vs. 8.83%±0.44%, P<0.05). Docetaxel could significantly increase late apoptosis and death of MCF-7 cells af-ter treatment over 24h (from 6.97%±0.75% to 20.77%±0.75%, P<0.05). Docetaxel combined with 4-AP could increase early apoptosis rate from 4.60%±0.91% to 12.20%±0.82% (P<0.05) and could increase late apopto-sis rate and death rate from 4.60%±0.91% to 12.20%±0.82% (P<0.05). Conclusion: Both docetaxel and 4-AP can inhibit the proliferation of MCF-7 cells. Docetaxel can increase the percentage of cells at G_2/M phase and 4-AP can increase the percentage of cells at G_0/G_1 phase. 4-AP could strengthen the inhibitory effect of docetaxel on the proliferation of MCF-7 cells through inducing cell apoptosis.
