AIM To investigate the dose-proportion relation of Tibetan medicine Siwei Jianghuang Prescription (SJP) for protective effects on diabetic nephropathy (DN),and the underlying mechanism.METHODS Diabetes mellitus rats induced by intraperitoneal injection of streptozotocin (STZ) (60 mg/kg) were randomly divided into model group,metformin support group,and eight SJP groups with dose-proportion variation (with reference to the uniform design method) for corresponding drug administration once a day,for four weeks.Measurement of fasting blood glucose (FBG) by a blood glucose meter,the concentrations of blood urea nitrogen (BUN),uric acid (UA),serum creatinine (SCr) and total protein (TP) by chemical methods,serum transforming growth factor-β1 (TGF-β1) and vascular endothelial growth factor (VEGF) by ELISA kits were conducted,the pathological morphology observation and glomerular basement membrane thickness detection by electron microscope were accomplished as well.Principal components analysis (PCA) and multivariate progressive regression analysis (MSRA) were employed to analyze the relationship between the dose-proportion to pharmacodynamics.RESULTS The resultant indexes revealed variant pharmacological improvement in each treatment group.MSRA results showed that the levels of BUN,renal index,FBG,glomerular basement membrane thickness,VEGF,Scr,and UA had correlative relations with a multiple linear or a multiple non-linear in all groups,which regression equation had a statistical significance (P < 0.05);TGF-β1 level and total protein index with the dose-proportion had no linear or non-linear relation,which the regression equation statistical showed non-significance (P > 0.05).In the global optimization comparison around the range of uniform design,the optimal dosage of the rats model was Curcumae Longae Rhizoma ∶ Berberidis dictyophyllae Cortex ∶ Phyllanthi Fructus ∶ Tribuli Fructus =1 ∶ 2 ∶ 1 ∶ 2.CONCLUSION Siwei Jianghuang Prescription shows better therapeutic effects on DN,which may be related to reducing the levels of BUN,renal index,FBG,glomerular basement membrane thickness,VEGF,Scr and UA.

To evaluate the relationship between p27Kip1 low expression in breast cancer and its prognostic implication in breast carcinoma patients. Methods All data that were associated with the study of the relationship between p27Kip1 and the prognosis for breast cancer was pooled from Cochrane library, PubMed, Embase and Medlinebase. The outcome was measured using the risk ratio (RR). Data pooling was performed by RevMan 4. 2. Results 6457 patients from 20 studies were included in this meta-analysis. RR estimate of overall survival (OS) for patients with low level p27Kip1 was 2.07 [1.66,2.60] (P<0.01). For disease free survival (DFS), the pooled RR was 1.27 [1.10,1.47] (P<0.05). The combined RR estimate of relapse free survival (RFS) for patients with low level of p27Kip1 was 1.49 [0.92, 2.42] (P >0.05). In patients with lymph node negative breast carcinoma, the combined RR for OS and RFS were 1.98 [1.34,2.91] (P <0.01) and 1.28 [0.45,3.65] (P > 0.05), respectively. Among the patients with lymph node positive breast carcinoma, the combined RR for OS and RFS was 1.92 [1.31, 2.82] (P=0.0009) and 1.35 [0.96,1.89] (P>0.05) respectively. Conclusions Low level of p27Kip1 appears to be an independent prognostic factor to OS and DFS of breast cancer patients but not to RFS. Additional studies with large patient number and widely accepted practical methods are required to derive the precise prognostic significance of p27Kip1 expression in breast cancer patients.

OBJECTIVETo explore the potential risk factors of intrahepatic cholangiocarcinoma (ICC) in China.
METHODA case-control study including 317 patients with pathologically confirmed ICC and 634 healthy individuals was conducted. The cases and controls were matched in age, sex and inhabitancy. Data were statistically analyzed by Chi-square test and conditional logistic regression.
RESULTSUnivariate analysis showed significant difference in HBsAg seropositivity, liver cirrhosis, hepatolithiasis, choledocholithiasis and schistosomiasis between ICC patients and healthy controls (P < 0.05). Multivariate analysis confirmed that HBsAg seropositivity, liver cirrhosis, hepatolithiasis and hepatic schistosomiasis were associated with ICC, and their adjusted odds ratio (95% confidence interval) were 10.265 (6.676-15.783), 13.101 (5.265-32.604), 18.242 (3.580-92.958), 18.435 (1.930-176.082), 15.102 (4.607-49.499) and 11.820 (3.522-39.668), respectively. The incidence of hepatic cyst, cholecystolithiasis, hepatic hemangioma, fatty liver, diabetes mellitus, smoking and drinking were not significantly different between ICC patients and controls.
CONCLUSIONSThe HBV infection, liver cirrhosis, hepatolithiasis and hepatic schistosomiasis may be the risk factors for ICC in China.

Objective To study the effect of emodin on protein and gene expressions of the massagers in mobility signal transduction system of cholecyst smooth muscle cells in guinea pig with cholesterol calculus. Methods The guinea pigs were randomly divided into 4 groups, such as control group, gall-stone (GS) group, emodin group and ursodeoxycholic acid (UA) group. Cholesterol calculus models were induced in guinea pigs of GS, emodin and UA groups by lithogenic diet, while emodin or UA were given to the corresponding group for 7 weeks. The histomorphological and ultrastructure change of gallbladder were detected by microscope and electron microscope, the content of plasma cholecystokinin (CCK) and [Ca

Objective To study the mechanism of insulin resistance in the cholesterol gallstone formation from insulin signal transduction pathway so as to reveal the possible mechanism and the effective role of Albiflorin Granule on preventing the cholesterol gallstones. Methods Serum triglycerides (TG), free fatty acid (FFA), and total cholesterol (TC) from different groups were measured and liver cells InsR, PKB, IKK-β protein expression levels were detected by western blotting. Results Albiflorin significantly decreased the cholesterol gallstone formation rate, increased glucose infusion rate in gallstone guinea pigs and improved insulin resistance. Compared with the normal group, insulin receptor and PKB protein expression in GS group were significantly reduced. IKK-β protein in the GS group increased significantly and Albiflorin could reduce IKK-β protein expression in guinea pig liver cells. Conclusions The model of insulin resistance in cholesterol gallstone guinea pig was successfully established, which plays an important role in the cholesterol gallstone formation. All aspects of insulin signaling pathway are involved in gallstone formation. Albiflorin can regulate various aspects of insulin signal transduction pathway to prevent the formation of gallbladder.

OBJECTIVETo evaluate the technique and significance of mastoscopic axillary sentinel lymph node biopsy.
METHODSSixty-two patients with breast cancer use methylene blue to test axillary sentinel lymph node. Sentinel lymph node was moved with endoscopy, and endoscopic axillary lymph nod dissection was performed. Pathological examination of sentinel lymph node and axillary lymph node was made with HE. To evaluate detection rate and false negative rate in sentinel lymph node.
RESULTSAmong the 62 patients, 61 were confirmed by endoscopic axillary sentinel lymph nod biopsy. Detection rate was 98.4%. Thirty-five cases were no metastasis, 27 cases were metastasis, false negative rate was 0.
CONCLUSIONSMastoscopic axillary sentinel lymph node biopsy has a high detection rate, good efficiency of cosmetic and lower complications. It has higher sensitivity than traditional axillary lymph nod dissection and provide accurate lymph node stages.

OBJECTIVETo evaluate the expression of three different RASSF1 transcripts and its clinical significance in lung carcinomas.
METHODSThe mRNA expression of RASSF1A, RASSF1B and RASSF1C was detected by RT-PCR in 51 human lung cancer tissues and 51 matched normal tissues.
RESULTS1. The mRNA expression of three RASSF1 transcripts was detectable in all non-cancer tissues. However, high rate of expression loss of RASSF1A and RASSF1B existed in lung cancer tissues, which was 53.2% (2851) and 37.3% (19/51), respectively. RASSF1C was expressed in all of the tumor tissues. 2. Loss or abnormal down-regulation of RASSF1A was positively related with lymph node metastasis and TNM stage (P < 0.05) and 3. RASSF1B and RASSF1C mRNA expression was not correlated with TNM stage, histological type, differentiation grade or smoking index.
CONCLUSIONThere is a significant expression difference among the three RASSF1 transcripts in lung carcinoma. RASSF1A, closely associated with lymph metastasis and TNM stage of lung carcinoma, should be a new tumor suppressor gene.
