Objective To investigate the genetic polymorphisms of the glutathione S-transferase M1 and T1 genes(GSTM1 and GSTT1),and eval-uate the oxidative damage in patients with non-small lung cancer(N-SCLC). Methods A total of 110 patients with N-SCLC and 100 healthy indi-viduals were recruited in this case-control study. Multiplex polymerase chain reaction(PCR)analysis was used to identify the genotypes. The activi-ty of malondialdehyde(MDA),nitric oxide(NO),and the total antioxidant capacity(T-AOC)were detected by spectroscopic analysis using assay kits. Results The frequencies of the GSTM1,T1,and GSTM1/T1 null genotypes in the patient group were significantly higher than those in control group(OR1=2.071,P1=0.009;OR2=1.900,P2=0.024;OR3=3.258,P3=0.003). The activity of MDA and NO were obviously higher in the pa-tient group compared with the control group(P<0.001),and T-AOC was obviously lower in patient group than those in control group(P<0.001). The activity of MDA,and NO were higher but the T-AOC were lower in patients with GSTM1,T1 and GSTM1/T1 null genotypes than those in pa-tients with GSTM1,T1 and GSTM1/T1 present genotypes(P<0.001). Conclusion Our results suggest that oxidative damage may play a impor-tant role in patients with N-SCLC,and the N-SCLC patients with GSTM1and GSTT1deletion genotypes are more susceptible to oxidative damage.

Objective To evaluate the efficacy of combination therapy with M and α receptors antagonist for the treatment of double-J stent related lower urinary tract symptoms.Methods From May 2013 to May 2014,131 cases,including 71 male and 60 female cases,were accepted the doubte-J stent indwelling after the ureteral lithotripsy,laparoscopic ureterlithotomy and pyeloureteroplasty.Their data was retrospectively reviewed.The age ranged from 29 to 64 years old,mean (47.4 ± 15.2) years old.They were divided into 4 groups randomly,including group A (control group,n =30),no drugs were taken;group B (tamsulosin group,n =34),0.2 mg tamsulosin was taken qd;group C (solifenacin group,n =32),5 mg solifenacin was taken qd;group D (tamsulosin combined with solifenacin group,n =35),0.2 mg tamsulosin and 5mg solifenacin were taken qd.The IPSS scores,QOL scores and visual analogue pain scale (VAPS) scores were assessed pre-operation,1 week after operation,and 4 weeks after operation,respectively.Results All patients were followed-up until the end of this study.In each time point,the IPSS scores in group A was 9.01 ± 2.79,13.18 ± 3.79 and 13.79 ± 3.76,respectively.In group B,the IPSS scores were 7.89 ± 4.29,12.39 ±3.90 and 12.21 ±3.87,respectively.In group C,the IPSS scores were 7.94 ±4.27,12.70 ±4.01 and 11.98 ±4.69,respectively.In group D,the IPSS scores were 8.21 ±3.18,11.97 ±5.03 and 8.17 ± 3.25,respectively.Significant difference in total IPSS scores and obstruction symptom scores were shown between pre-and post-operation (P ＜ 0.05).Comparing to other groups,group D exhibited the significant improvement in IPSS scores 1 and 4 weeks after the operation (P ＜0.05).4 weeks after operation,the QOL scores in group D was significantly lower than that in other groups (P ＜ 0.05).While the VAPS scores didn t show significant differences among those groups (P ＞ 0.05).Conclusion M and α receptors antagonist combination therapy can significantly improve lower urinary tract symptom due to indwelling double J stents.

Objective to investigate the correlation between glutathione S- transferase gene M1,t1 and P1(GStM1,GStt1 and GStP1)poly-morphism and sperm DNA fragmentation index(DFI)in male patients with idiopathic infertile. Methods the study included 246 male patients with idiopathic infertility. Polymerase chain reaction(PCR)and polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP) were used to identify the genotype of GStM1,GStt1 and GStP1,respectively. Sperm DFI was analyzed by flow cytometry with acridine orange staining. Results the sperm DFI was significantly higher in GStt1 gene null type group than in GStt1 gene wild type group(P < 0.01);and there were no significant differences in GStM1 and GStP1 gene mutation type groups when comparing with the wild type group(P > 0.05). Conclusion GStt1 gene deletion was positive associated with the sperm DFI in male idiopathic infertile patients.

Objective Tamm-Horsfall protein (THP) may play a role in kidney stone formation.The article aimed to conduct a preliminary study on the role of THP in kidney stone formation by investigating the changes of THP in rat urine, pathological changes of renal tissue and the formation of calcium salt crystals after establishing CNPs rat model of kidney stones.Methods Stone samples of 40 patients from February to June 2015 in our department were collected to establish the model of CNPs-induced kidney stone in rats and prepare CNPs suspension.48 SD rats were randomly divided into experimental group (group A) and blank control group (group B).Group A were injected with CNPs and the same amount of sterile saline injection in the group B.The urine of rats was collected after injection at 3h, 6h, 12h, 24h, 1w, 2w, 4w and 8w.ELISA were applied to detect THP levels in the urine.Then the rats were killed to take the kidney tissue.HE staining was used to investigate the pathological changes of the cells and evaluate the formation of the calcium salt crystals.Results THP levels in group A at 24h, 1w, 2w, 4w and 8w ([166.03±3.02], [173.50±1.78], [174.55±2.05], [176.54±2.45], [177.11±1.76]pg/mL) were significantly higher than that at 3h(165.89±2.23pg/mL)(P<0.05), which was the same case in comparison with those of group B ([157.65±2.22], [156.54±1.43], [159.45±3.21], [158.63±2.98], [157.33±2.05]pg/mL).Compared with the calcium salt crystal score at 6h (1 point), the scores at 3,6,12,24h (average score 2 points) increased.At 2w the score increased significantly to 3 points and reached the top score(6.7points) at 8w, which was of significant difference.The score of calcium salt crystals was in positive correlation with THP content (r=0.843,P<0.05).Conclusion THP in urine may contribute to the aggregation of calcium salt crystals and the formation of kidney stones.
