Objective To investigate the effects of Donglian Capsule(the combination of Ophiopogonis Tuber Polysaccharide with Rhizoma Coptidis Alkaloids, OPRA for short, Component of Chinese medicine)on early insulin resistance in experimental diabetic rats. Methods The animal model of insulin resistance in 2 type diabetic was established by injecting low dose of STZ in 60 high fat-fed SD rats. After one week, the successful models were randomly divided into 4 groups: untreated, high and low OPRA-treated, mefformin-treated group, Meanwhile, a normal control group was designed. After four weeks, the differences of FBG, PG, INS and C-P were compared among the groups. Results The OPRA can significantly reduced the level of serum TC and FBG, increased the C-E ]Lightened the IRI(P<0.01). Conclusion The OPRA can reduce the level of serum TG and FBG, and decrease insulin resistance to protect the β-cell function.

Objective To investigate the monocyte chemoattractant protein (MCP1) gene expression of the bladder urothelial carcinoma and its correlation with the pathogenesis of the bladder urothelial carcinoma.Methods Thirty cases of patients with the bladder urothelial carcinoma, including 20 cases of male and 10cases of female, were taken the blood and bladder tissue.In control group, 30 cases of non-cancer patients,including 20 cases of male and 10 cases of female, were taken the blood samples.ELISA method was used to detected the concentration of plasma MCP1, immunohistochemical method to investigate the expression of MCP1 in the bladder urothelial carcinoma and adjacent tissues.Real-time quantitative RT-PCR was applied to detected the expression of MCP1. Data of the two groups were comparied and the relationship between the expression of MCP1 and the clinical characteristics of the bladder urothelial carcinoma was analyzed.Results MCP1 in group of patients with the bladder urothelial carcinoma was (193.4±105.7) pg/ml, and higher than that in non-tumor group (91.8±34.6) pg/ml (t = 8.37, P ＜0.001).MCP1 in invasive bladder cancer was (204.3±167.5) pg/ml and superficial bladder cancer was (130.6±69.2) pg/ml (t = 2.667, P = 0.013). By immunohistochemistry, the MCP-1 positive rate in the bladder urothelial carcinoma was 70.0 % (21/30), that in adjacent cancer tissue was 43.3 % (13/30) (χ2 = 4.9, P ＜0.05). The positive rate of MCP1 in invasive bladder cancer in tumor group was 80.0 % (8/10) and that in superficial bladder cancer was 65.0 %(13/20).At the same time, MCP- 1 positive intensity in the bladder urothelial carcinoma was significantly higher than that in adjacent tissues. The intensity in invasive bladder cancer was higher than that in superficial ones. Total RNA and mRNA levels of MCP-1 in the bladder urothelial carcinoma were statistically differences compared with that in adjacent tissues (χ2 = 10.08, P ＜0.05).Conclusion The upregulation of MCP1 gene expression is likely to play an important role in the incidence and metastasis of the bladder urothelial carcinoma.

Objective To investigate the clinical features and treatment of aggressive angiomyxoma of the genitourinary system. Methods Two cases of aggressive angiomyxoma of the genitourinary system were reviewed. One case was a 55 year old man.He presented with a painless inguinal mass which was indicated in low echo by ultrasound;and he underwent surgical complete excision.The other case was a 14 year old female presenting with frequent urination,hematuria,dysuria and urethral mass.After the IVU,CT and 3 dimensional CT examination revealed the extent and blood supply,partial cystectomy and ureteroneocystostomy were performed on her. Results The 2 patients were followed up for 2 to 6 months after surgery,with no recurrence and metastasis.Case 1 was diagnosed with aggressive angiomyxoma involving the spermatic cord and the immunohistochemical testing was positive for Vimentin and SMA,negative for Desmin and S 100.Case 2 was diagnosed with aggressive angiomyxoma of the urinary bladder and the immunohistochemical testing showed that the cancer cell was positive for CD 34 ,SMA,Vimentin,and negative for Desmin,Caldesmon,ER,PR and S 100. Conclusions Aggressive angiomyxoma is a rare,benign and locally aggressive neoplasm.The histopathologic and immunohistochemical studies reveal the definite diagnosis.The therapy is surgical excision as complete as possible.Radiotherapy combined with endocrinotherapy may be used for recurrence and difficult excision of the tumor.Long term follow up and close monitoring with imaging techniques are essential for timely identification of recurrence and for prompt resection.

Objective To study the expression and significance of galanin (GLA) in the prostate carcinoma (PCa).Methods The samples from 50 patients with benign prostatic hyperplasia (BPH) and 50 patients with PCa and 30 PCa patients with bone metastasis were examined by immunohistochemical staining.Results The positive rates of GLA expression in BPH,PCa,and PCa with bone metastasis were 18 ％ (9/50),68 ％ (34/50),and 80 ％ (24/30),respectively,and there were statistically significant differences between PCa patients,PCa patients with bone metastasis and BPH patients (x2 =25.5,29.74,both P ＜ 0.01),but there was no significant difference between PCa patients and PCa patients with bone metastasis (x2 =1.35,P ＞ 0.05).Conclusion GLA has higher expression in prostatic cancer cells,it might be an important indicators for differentiating prostate cancer from benign prostatic hyperplasia and predicting the prognosis of prostate carcinoma.

Objective: To explore the relationship of plasma apelin and angiotensin II (Ang II) with hypertension and hypertension caused early renal damage in order to provide the information for hypertension treatment. Methods: A total of 671 participants were enrolled in this cross-sectional community investigation. All participants were above 30 years of age with local residency longer than 5 years and were divided into 2 groups: Control group,n=354 non-hypertension subjects and Hypertension group,n=317 patients with essential hypertension. The levels of apelin, Ang II, urine creatinine and urinary albumin were examined. The relationship between blood pressure and the ratio of urinary albumin to urine creatinine (UACR) and the relationship between blood pressure and apelin, Ang II were studied by Pearson correlation analysis and multi linear regression analysis. Results: Compared with Control group, Hypertension group had the lower levels of apelin and higher UACR, both P<0.01. The mean arterial pressure (MAP) was negatively related to Ln (apelin), positively related to Ln (Ang II), bothP<0.01. With adjusted gender, age and blood lipids, the above relationship still existed. In Hypertension group, the patients combining with the early renal damage had the lower level of apelin and higher level of Ang II, bothP<0.01. The relevant analysis indicated that Ln (UACR) was negatively related to Ln (apelin), positively related to Ln (Ang II), bothP<0.01. With adjusted gender, age, MAP and blood lipids, the above relationship still existed. Conclusion: The patients with hypertension or hypertension caused early renal damage have decreased apelin. Apelin is negatively related to Ang II, therefore, apelin might be used as a target for hypertension treatment in clinical practice.
