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 investigate the clinical efficacy of TongluoShu Liquid in treating rheumatoid arthritis at early stage. Methods 100 cases were randomly recruited into a control group and a treatment group with 50 cases in each group. The treatment group was given TongluoShu liquid, 150ml / time, twice a day; and the control group was given Diclofenac Sodium Sustained Release Tablets (Deegan), one granule for each time, twice a day, and Methotrexate 7.5mg / time, once per week. Results In the treatment group, symptoms, signs and biochemical indicators were significantly improved, and the swelling of the soft tissue around the joints in stage Ⅰ and Ⅱ were also reduced. Besides, osteoporosis was controlled and the progress of destruction to the cartilage of stage Ⅲ was detained, though there was no statistical difference between the two groups after the treatment. Conclusion ShuTongluo liquid is a safe and effective medicine with less adverse reactions in treating rheumatoid arthritis.

Objective To investigate the genetic variants in the protein C (PC) and endothelial protein C receptor (EPCR) genes associated with the risk and outcome of acute respiratory distress syndrome (ARDS) patients in Chinese Han race.Methods Five tagSNPs (single nucleotide polymorphism,SNP) in the PC and EPCR genes were genotyped in patients with ARDS (n =275) and non-ARDS (n =337) in order to find the association between them in this case-control study.The SNPs were genotyped by SNPstream Beckman platform.Then,the correlation between the associated SNPs and plasma levels of activated protein C (APC) in patients with ARDS was investigated.The APC levels were measured using enzyme linked immunosorbent assay (ELISA) method.Results Association analysis rcvealed that two PC SNPs in perfect linkage disequilibrium,rs1799809 and rs1158867,were significantly associated with susceptibility to ARDS.T allele frequency of rs1799809 in ARDS patients was significantly higher than that in non-ARDS patients (OR =1.569,95％ CI:1.192-2.066).And the genotype frequencies of rs1799809 were also significantly different between these two groups (P =0.007).The association remained significant after adjustment for multiple comparisons.Haplotype consisting of three SNPs in the PC gene was also associated with susceptibility to ARDS.The frequency of haplotype CCC in the ARDS samples was significantly lower than that in the non-ARDS group (P ＜ 0.01).Moreover,ARDS patients canrying rs1799809 TT genotype showed lower serum levels of APC than patients with TC and CC genotypes (Padj =0.02).However,genotype and allele analyses of EPCR did not show any significant difference between ARDS and non-ARDS patients.Conclusions These findings indicated that common genetic variation in the PC gene was significantly associated with susceptibility to ARDS in Chinese Han race.The PC genetic variation influenced plasma concentration of APC in patients with ARDS.
