Objective To explore the relationship of leptin、 Glutathione peroxidase (GSH-Px) and other correlative factors with type 2 diabetic fatty liver. Methods From 2003-10 to 2004-01, we examined leptin、GSH-Px、 blood fat in the serum and BMI、FAT% in 23 cases of type 2 diabetic fatty live、30 cases of type 2 diabetic inpatients and 30 healthy people. Compare their level and analyse the correlation. Results (1)The TG、BMI、FAT% of type 2 diabetic fatty liver patients were significantly higher than that of the others groups. (2)Leptin and GSH-Px of each group had significant changes. Leptin was correlative with FAT% and age. GSH-Px was correlative with age and HDL. Conclusion (1)TG、 BMI and FAT% are important risky factors. (2)There are leptin resistance in type 2 diabetic fatty liver and type 2 diabetes patients and it is influenced by obesity and age. (3)The antioxidant enzyme in the serum of type 2 diabetes patients is reduced and is related with age and HDL.

Objective To evaluate the outcome of a new modality of operation—tensionfree vaginal tape (TVT) in treatment of female stress urinary incontinence. Methods Thirteen female patients suffering from stress urinary incontinence were treating with TVT operation.All the patients were confirmed to have stable bladder without outlet obstruction via clinical routine and urodynamic examination before operation.TVT tape of Prolene was implanted around mid-urethra via a minimal vaginal incision. Results The mean operation time was (38?7)min and the mean intraoperative bleeding was (45?10)ml.The mean catheterization time was 2 days and mean hospital stay was 4 days.No major bleeding was observed in operation.All patients were cured and the clinical symptoms disappeared after operation except for one patient with post-operative urine retention.This patient was catheterized for 2 weeks and the tape was cut under local anesthesia;then the urine retention disappeared and no incontinence relapsed. Conclusions TVT is a simple,reliable mini-invasive procedure with low incidence of complications.It can be used routinely for treating female stress urinary incontinence.

OBJECTIVE: To investigate the effects of Wenyang Huoxue Recipe (WRHXR), a compound traditional Chinese herbal medicine for warming yang and promoting blood flow, on the expression of angiopoietin mRNA in rats with chronic aristolochic acid nephropathy induced by Caulis Aristolochia Manshuriensis (CAM) decoction, and to explore the protection mechanism of WYHXR against kidney damage. METHODS: Twenty-eight male SD rats were randomly divided into normal control group, CAM group and WYHXR-treated group. Rats in the normal control group (n=8) and CAM group (n=10) were intragastrically administered with normal saline 10 ml/(kg.d) or CAM decoction 10 ml/(kg.d) respectively. Rats in the WYHXR-treated group (n=10) were intragastrically administered with WYHXR 30 g/(kg.d) and CAM decoction 10 ml/(kg.d). The expressions of Ang-l and Ang-2 mRNAs were detected by real-time reverse transcription polymerase chain reaction (RT-PCR) after 20-week treatment. RESULTS: Compared with the normal control group, the expression of Ang-l mRNA was significantly decreased, and the expression of Ang-2 mRNA was significantly increased in the CAM group (P<0.01). Compared with the CAM group, the expression of Ang-l mRNA was increased in the WYHXR-treated group (P<0.01). The expression of Ang-2 mRNA had no significant difference between the CAM group and the WYHXR-treated group (P>0.05). Renal pathology showed that renal damage in WYHXR-treated group was significantly reduced as compared with the CAM group. CONCLUSION: WYHXR can up-regulate the expression of Ang-l mRNA, which may be its action mechanism in protecting the kidneys.

Objective To investigate the association between gene polymorphism of plasminogen activator inhibitor (PAI-1)and ischemic cerebrovascular disease in aged people of Henan Han nationality.Methods A case control method was used,including 408 patients with ischemic cerebrovascular disease and 418 age and gender matched healthy controls.Polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method was used to determine the distribution of allele and genotype frequencies of PAI-1 844G/A.Results In patient group,the gene frequencies of AA,AG,GG were 18.1％,41.4％,40.4％,and the A and G allele frequencies were 38.8％ and 61.2％,respectively.In the control group,the gene frequencies of AA,AG,GG were 15.8％,47.4％,36.8％,and the A and G allele frequencies were 39.5％ and 60.5％.There were no significant differences in the frequencies of genotypes and alleles between the two groups (P＞0.05).The different genotypes of 844G/A of PAI-1 gene were not associated with hypertension,hyperglycemia,plasma homocysteic acid levels (P ＞ 0.05).Conclusions PAI-1 gene-844G/A polymorphism may not be independent risk factor of ischemic cerebrovascular disease in aged people of Henan Han nationality.
