Objective: To study the practical value of a new techinigue of perforating vein ligation. Methods: Enlightened by Subfascial Endoscopic Perforator, we isolate perforating vein in subfasica through little incision, and then ligate and cut perforating vein. The change of the symptoms and signs were observed, and the clinical severity grade of pre-operation were compared with that of post-operation. Results: The symptoms and signs of patients are improved after operation, and the clinical severity grade of postoperation of the patients was significant different, comparing with that of pre-operation. Conclusion: The effect of perforating vein ligation through little incision at subfascia is effective and its complications are few.

It has been confirmed that tumor invasion and metastasis is not only dependent on the charac -teristics of the tumor ,but also dependent on the tumor microenvironment .Tumor-associated macrophage ( TAM) , which constitutes a large number of the tumor -infiltrating immune cells,is stimulated into M1 macrophage and M2 macrophage by different signals in the tumor microenvironment .Whereas the vast majority of studies with nu-merous tumor types show that the presence of M 2 phenotypes in the tumor microenvironment is associated with a worse prognosis ,most studies in gastric cancer also claim the same results .Hypoxia and coagulation factors may both contribute to it .It has identified that the function of TAM could be changed with their location of tumor ,but it has nothing to do with cell differentiation and cell type of gastric cancer .In this review,we summarize the differ-ent and controversial effects of TAM in gastric cancer .

Objective To explore the related risk factors of type 2 diabetic nephropathy,and to provide theoretical basis to make the strategy of prevention of diabetic nephropathy.Methods By case-control study method,98 patients with type 2 diabetic nephropathy were selected as the observation group.98 diabetes mellitus patients without kidney disease were selected as control group.Single factor analysis and non-conditional logistic regression analysis were conducted in two groups.Results The results of single factor analysis showed that type 2 diabetic nephropathy was closely related to family history of diabetes,course of diabetes,high blood pressure,diabetic retinopathy,BMI,coronary heart disease,HbAlc,FPG,2hPG,CRP (P ＜ 0.05).The results of multiple factors of logistic regression showed that type 2 diabetic nephropathy was closely related to course of diabetes and diabetic retinopathy,CRP,HbA1c,FPG(P ＜0.05).Conclusion Course of diabetes and diabetic retinopathy,CRP,HbA1c,FPG are independent risk factors for type 2 diabetic nephropathy.

Objective To establish a new approach for quantitative detection of VAD1 mRNA in cryptococcus neoformans by RT-FQ-PCR, and evaluate the treatment efficacy of CNM. MethodsThe primers and TaqMan probe were designed according to the published sequence of VAD1 mRNA (GenBank),and RT-FQ-PCR method to detect VAD1 mRNA was established. Cerebrospinal fluid from 25 CNM patients and 30 controls were detected and sensitivity and specificity of the method were evaluated. VAD1 mRNA concentration in cerebrospinal fluid from both acute phase and recovery phase of 25 CNM patients were also detected and significance of CNM treatment efficacy with VAD1 mRNA analysis was evaluated. Results Correlation coefficient of standard curve was - 0. 997 9 in detection of VAD1 mRNA by RT-FQ-PCR, and the detection limit was 101 copies/μl. The intra CV of plasmid standard for high, medium and low concentrations were 0. 65% ,0. 89% and 1.23% respectively, the sensitivity of cryptococcus neoformans detection by RT-FQPCR was 96% (24/25) ,while specificity was 100% (30/30). VAD1 mRNA concentration in acute phase were significant higher than that in recovery phase (3. 042 ±0. 906 vs 2. 187 ±0. 665 ,t =4. 583 ,P ＜0. 01).Conclusions The established RT-FQ-PCR method for the detection of VAD1 mRNA is provided with sound sensitivity, specificity and reproducibility, which might be fit for the detection of VAD1 mRNA. The expression level of VAD1 mRNA is relevant with the treatment efficacy of CNM.

Objective: To evaluate the effectiveness that gelatin lines the injured vasuclar wall to prevent from restenosis.Methods: The animal model of restenosis was established by balloon dilation in femoral artery,and 30% gelatin was lined on injured vascular wall in experimental group.The samples were collected at the 2nd week and 4th week after operation.The neointimal area(NEA),neointimal area/media area(NEA/MA)and cell apoptosis were observed by image analysis system and TUNEL technique. Results: The intima of the control group was thicker than that of the experimental group,and more cells appeared in the control group.Compared with the control group,the NEA was reduced significantly in the experimental group at the 2nd and 4th week (0.67?0.25cm 2 vs 1.02?0.41cm 2,and 1.18?0.36cm 2 vs 1.46?0.15cm 2).The NEA/MA ratio in the experimental group was lower than the control group at the 2nd and 4th week(0.35?0.05% vs 0.54?0.14%,and 0.62?0.25% vs 0.75?0.10%).The apoptosis rate of vascular smooth muscle in the experimental group was higher than the control group at the 2nd and 4th week(18.2?5.8% vs 13.6?2.4%,and 15.1?2.1% vs 13.0?1.5%).These diffences were all significant (P

Objective To study the sex difference among PHC patients' ABO blood types and HBV infection,hepatic cancer family history,drunking alcohol hobby in Guilin district.Methods 192 cases of PHC were classified according to sexes,we compared the ABO blood types distribution,HBV infection,family history of PHC and drunking alcohol hobby between the two sexes.Results PHC infective ratio of male to female was 85.94∶14.06;the O blood type distribution in the male was more than that of the female's(P

Conclusion: Different processed method and temperature can effect the contents of organic acid on Fructus crataegi.

0bjective To study the expression of Fas in hippocampus of cerebral ischemia-reperfusion rats after treatment with monosialoganglioside (GM1). Methods Seventy-two SD rats were randomly divided into sham group (n=8), GM1 treatment group (n=32) and ischemia-reperfusion (I/R) group (n=32). According to the different time points (6 h, 12 h, 24 h and 3 d) of I/R, there were four subgroups in GM1 and I/R groups respectively. The expression of Fas in hippocampus was examined by immunochemistry and Western blot methods in all groups. Results Results of immunochemistry method showed that there was a little expression of Fas (the mean optical density was 0.17±0.02) in hippocampus of sham group, and the positive expression of Fas at different time points were increased significantly after reperfusion. The mean values of opti-cal density at different time points were 0.42±0.11, 0.51±0.13, 0.55±0.13 and 0.62±0.15 in I/R group, which reached to the peak at 3 d . The positive expression of Fas at different time points were significantly decreased in GM1 group (0.29 ± 0.09, 0.34±0.11, 0.37±0.12 and 0.43±0.12) than that of I/R group (P＜0.05). Conclusion Monosialoganglioside participated in the pathogenesis of cerebral ischemia-reperfusion injury by down-regulating the expression of Fas.

Objective To evaluate the clinical efficacy and surgical method in radical debridement and spinal fusion with internal fixation in surgical management of cervical vertebra tuberculosis.Methods Twenty-one patients of cervical vertebra tuberculosis were included,mean age of 31 years,including 2 cases at C_(1-2),3 at C_(2-3),9 at C_(4-5),3 at C_(5-6),3 at C_(6-7),1 at C_7T_1.After all patients underwent radical debridement of focuses,15 cases were grafted with iliac bone and 6 with titanium mesh,19 cases were fixed with plate,1 case with Apofix,1 case with Occipital-cervical fusion.The external fixation was needed for 3 months after surgery.Results The follow-up lasted for 21 months.One case grafted with titanium mesh failed,but other patients achieved satisfactory results of successful interbody fusion within 3 to 6 months.The kyphosis deformity was corrected to normal condition without associated complications.The neural symptoms were improved.All patients had no recurrence of tuberculosis.There were no plates and screws broken.Conclusion It is safe and effective to treat cervical vertebra tuberculosis by anterior radical debridement and primary autograft by internal fixation,with high correction rate of local kyphosis deformity,high fusion,and low complication rate.
