Objective To observe the effect of two different methods of fixed temporary pacemaker electrode. Methods Fromn April 2015 to December 80 temporary pacemaker patients were randomly divided into control group (n = 40) and the experimental group (n = 40), the control group using gauze cloth tape cross method combined with the traditional fixed, the experimental group was treated with 3M type of comfortable and stable transparent dressing+3M pressure fixing belt fixed, to compare two groups in the skin lesions, electrode dislocation, inflammatory reaction, the switching frequency difference. Results There was no significant difference between the two groups in general data (P>0.05). There was no significant difference between the two groups in the cost of dressing and materials、electrode dislocation (P>0.05), experimental group of the switching frequency is lower than the control group (Z=-2.064, P<0.05), the differences were statistically significant. Conclusions 3M comfortable type solid transparent sticking and 3M pressurized fixed band method in the absence of increased medical costs while ensuring medical safety, save the manpower cost.

30%. For inferior genicular artery lesions,only balloon angioplasty were carried out. All patients were followed up for 6 months and 12 months to assess of restenosis and clinical efficacy. Results All the patients' therapy was successful,their clinical symptoms were improved or disappeared. The 6-month follow-up showed that restenosis rates were 5.5%,16.7% and 25% respectively in the iliac artery,femoral popliteal artery,and inferior genicular artery. The rates in 12-month follow-up were 11.1%,33.3%,and 75% correspondingly. Conclusion Angioplasty and stent implantation are safe and effective in treatment of lower limb atherosclerosis obliterans. Standardized postoperative anti-platelet,anticoagulant,and anti-lipid therapy is essential to maintain blood vessel recanalization.

Objective To analyze the polymorphism of thymidylate synthase(TS)in colorectal cancer patients,further more,to provide guidance for personalized therapy of colorectal cancer.Methods PCR direct sequencing was used to detect the polymor-phism of TS in 252 patients with colorectal cancer.Results TS genotypes of 252 patients with colorectal cancer were detected total-ly,including 137 male and 115 female.3RG/3RC accounted for the largest proportion in both male and female(36.50% and 36.52%respectively).In female,2RC/3RC and 3RG/3RG both accounted for the second largest proportion(both 18.25%).While in fe-male,3RG/3RC accounted for the second largest proportion(26.09%).If patients were divided according to age groups,in youth patients(n=28),3RG/3RC accounted for the largest proportion(42.86%),and the second was 2RC/3RG(21.43%).In the middle aged patients(n=84),3RG/3RC(45.24%)and 2RC/3RC(16.67%)were the major genotypes.For old patients(n=115),the ma-jor genotypes were 3RG/3RC(36.52%)and 2RC/3RG(16.52%).Conclusion The polymorphism of TS are mainly 3RG/3RC in colorectal cancer patients.

Objective To characterize the effects of AQP1 expression on kidney damage in rat disseminated intravascular coagulation(DIC) caused by lipopolysaccharide(LPS) dosing. Method Fifty male Wistar rats (clean grade) were randomly assigned into 5 groups of 10 rats. The 10 control rats were dosed with 10 ml of 0.9%NaCl solution by a drip via the vena caudalis within 4 h, and blood and tissues were obtained after treatment completion. In the DIC groups, the rats were dosed with LPS (30 mg/kg body weight in 10 ml of 0.9% NaCl solution) by a drip via the vena caudalis within 4 h, and blood and tissues were obtained at 4, 6, 8 and 10 h. The blood platelet(PLT) count, prothrombin time(PT) , activated partial thromboplastin time(APTT), fibrin(FIB) and D-dimer(D-D) were detected. Hematoxylin and eosin(HE) staining was used to examine the pathologic changes in the lung and kidney tissues of each group (both hematologic parameters and tissue pathologic changes were used to judge the course of DIC). The AQP1 gene expression levels in the kidney tissues from the groups were evaluated by the mRNA levels using RT-PCR. Statistical analyses were performed by the SNK- q method. Results The PLT count, PT, APTT, FIB and D-D examinations revealed remarkable changes in all DIC groups compared with the control group (P < 0.01). The AQP1 mRNA level was significantly decreased in the DIC group at 4 h compared with the control group (P < 0.01) , and further decreased to the minimum level in the DIC group at 6 h. Moreover, cloudy swelling of renal tubular cells was observed at 6 h and cell degeneration and necrosis were observed at 8 h among the DIC groups. Conclusions Downregulation of AQP1 mRNA expression occurred before damage to the renal tubular cells in DIC, indicating that AQP1 expression may be involved in the kidney damage observed in rat DIC.

Objective To study the correlation between vascular endothelial growth factor(VEGF) and cyclooxygenase-2 (COX-2) in clear renal cell carcinoma (CRCC).Methods In 60 cases of CRCC and 10 cases of normal renal tissue,immunohistochemistry was used to examine the expression of COX-2 and VEGF.Results The positive expression rate of COX-2 in CRCC (76.7％) was significantly higher than that in normal renal tissue (20％) (x2 =10.28,P ＜0.01).The positive expression rate of VEGF in CRCC(73.3％) was significantly higher than that in normal renal tissue (20％) (x2 =8.58,P ＜0.01).The expressions of COX-2 and VEGF in CRCC were correlated with each other (r =0.469,P ＜0.01).Conclusions The expressions of COX-2 and VEGF were involved in the pathophysiolical processes of clear renal cell carcinoma.The expression levels of COX-2 and VEGF might be used to evaluate the development of clear renal cell carcinoma.

BACKGROUND:It is controversial whether anterior approach alone, or combined anterior and posterior approaches were used for high level and multiple segments of severe ossification of cervical posterior longitudinal ligament.
OBJECTIVE:To explore the difference of anterior approach versus combined anterior and posterior approaches for the treatment of high level and multiple segments of severe ossification of cervical posterior longitudinal ligament.
METHODS:A total of 21 cases of high level and multiple segments of severe ossification of cervical posterior longitudinal ligament were included in this study. There were 9 males, aged 56-72 years, and 12 females, aged 58-70 years. We used anterior decompression and titanium mesh bone graft fusion in 11 cases which lesion located between C2-5 vertebra, and ossification excision, combined anterior (titanium mesh plate and screw) and posterior (lateral mass screw) approaches in 10 cases which between C3-7 vertebra. Japanese Orthopaedic Association score system was used to evaluate the results. The excellent and good rate and improvement rate were calculated.
RESULTS AND CONCLUSION:The excellent and good rate was 90%and improvement rate was 82%in 10 cases using combined anterior and posterior approaches. The excellent and good rate was 73%and improvement rate was 73%in 11 cases using anterior treatment alone. Significant differences in the excellent and good rate and improvement rate were detected between the two groups (P<0.05). These suggested that combined anterior and posterior approaches for high level and multiple segments of severe ossification of cervical posterior longitudinal ligament is a better operative procedure.
