Objective To determine the role of liver function test in the preoperative diagnosis of concomitant asymptomatic common bile duct (CBD)stone in patients with cholecystolithiasis.Methods A retrospective study was conducted from January 2012 to October 2013 at the Department of Hepatobiliary Surgery,the Affiliated Hospital of Zunyi Medical College on 426 patients who were operated for cholecystolithiasis.According to whether they had abnormal liver function,these patients were divided into the CBD stone group (n =44) and the cholecystolithiasis group (n =382).The values of the different components of liver functions test such as ALT,AST,AKP,GGT,TBIL and DBIL in diagnosing CBD stone were statistically analyzed.Results This study involved 426 patients,159 men and 231 women,with a mean age of (50.96 ± 12.93) years.44 patients with both CBD stone and cholecystolithiasis.The rates of abnormal liver function were 77.27％ (34/44) vs 4.45％ (17/382) in CBD stone group vs cholecystolithiasis group.The difference was significant (x2 =198.54 ; P =0.000).In logistic regression analysis,only elevated serum level of GGT (OR =10.067 ; P =0.007) remained as an independent predictor of CBD stone.On ROC (receiver operating characteristic) curves analysis,the area under the curve was 0.881.With a cut-off point for GGT at 84.5 U/L,there was a sensitivity of 72.2 per cent,specificity of 96.1 per cent,and positive and negative predictive values of 76.3 per cent and 96.2 per cent respectively.Conclusion Our study showed that liver function,especially GGT,was a predictor of CBD stone.

AIM:To investigate the expression of poly(ADP-ribose) polymerase-2 (PARP-2) during rat car-diac hypertrophy in vitro and in vivo, and to explore the effects of PARP-2 on the cardiac hypertrophy.METHODS:Ab-dominal aortic coarctation ( AAC) was performed to establish a model of pressure overload-induced cardiac hypertrophy in SD rats.The expression of PARP-2 at mRNA and protein levels in the myocardium was determined by real-time PCR and Western blot.The hypertrophy model of the cardiomyocytes was induced by treating the cells with angiotensinⅡ( AngⅡ) . PARP-2 was knocked down by siRNAs in neonatal rat cardiomyocytes and the cardiomyocyte hypertrophy was evaluated by measuring the mRNA levels of ANF, BNP, and β-MHC and the cellular surface area.RESULTS: The expression of PARP-2 at mRNA and protein levels was both increased in the AAC rats as compared with those in the sham animals.The expression of PARP-2 at mRNA and protein levels was also increased in a time-and concentration-dependent manner in AngⅡ-induced hypertrophy model of the cardiomyocytes.In the neonatal rat cardiomyocytes, knockdown of PARP-2 ex-pression by siRNA attenuated AngⅡ-induced cardiac hypertrophy of the cardiomyocytes, indicating that endogenous PARP-2 played a positive regulatory role in cardiac hypertrophy.CONCLUSION:The mRNA and protein levels of PARP-2 in-crease in the in vitro and in vivo models of cardiac hypertrophy.Knockdown of PARP-2 protects cardiomyocytes from hyper-trophy.

Objective To investigate the effects of three laparoscopic bariatric operations on relieving type 2 diabetes in morbid obese patients. Methods From 2005 to 2009, 15 morbid obese patients with type 2 diabetes received bariatric operations in Shengjing Hospital including lapband operation (7 cases) , sleeve gastrectomy (7 cases) and gastric bypass(4 cases). All patients were followed up for more than 1 year. Results All patients recovered without major complications. Body weight decreased and BMI was respectively (27. 6 ± 2. 0) kg/m2, ( 26. 9 ± 1. 4) kg/m2 and (27. 5 ± 3. 0) kg/m21 year after operation. The excess BMI loss in three groups were (76. 4% ± 6. 8% ) , (83. 7% ± 4. 6% ), (85. 7% ±9. 5% ) 1 year after operation. On the other side, the fasting glucose levels and glycohemoglobin in gastric bypass group were much lower than that in other two groups. Conclusion All these operations were effective in controling the weights and fasting glucose levels, while the gastric bypass method is better than other two methods in weight and serum glucose control. Sleeve gastrectomy was better in weight and glucose control than lap band operation.

Objective To study the effect of Jieyuyubao prescription on endometrial pinopodes and HOXa-10 mRNA in chronic stress rats , and reveal the regulatory mechanisms of the endometrial receptivity. Methods Totally 48 SPF SD rats were randomly divided into three groups with weight stratified: normal control group (group A), model control group (group B) and experimental drug group (group C). Rat model of chronic stress was established in group B and group C. On the first day of stimulation, Jieyuyubao solution (1 g·mL-1 ) was intragastrically administered (11. 8 mL·kg-1 ) to the rats of group C at 9:00 am, once daily, and stopped giving at the fourth day of pregnancy (pd4) after being confirmed by vaginal smears. Purified water (11. 8 mL·kg-1 ) was intragastrically administered to the rats of group A and group B at 9:00 am. All the rats were mated at the sex ratio of female:male = 2:1 at 16:00 pm on the 21st day. The rats were sacrificed at the pd4. Maturity of endometrium pinopodes was assessed under transmission electron microscope. HOXa-10 mRNA content was evaluated by real-time fluorescence-PCR. Results The maturity of pinopodes was as follows: the maturity score of normal control group, model control group and experimental group was (2. 7 ± 0. 3), (1. 3 ± 0. 3), and (2. 1 ± 0. 2), respectively, with significant difference between experimental drug group and model control group (P<0. 05). HOXa-10 mRNA expression was significantly decreased in model control group (0. 658±0. 031) as compared with normal control group (0. 965±0. 102) (P<0. 05). Conclusion Jieyuyubao prescription maybe increase the number and maturity of pinopodes through promoting HOXa-10 mRNA expression in endometrial epithelium cells, and then improve endometrial receptivity.

Objective: To observe the effects of Yanggan Lidan Granule (YGLDG), a compound traditional Chinese herbal medicine, on insulin resistance in guinea pigs with induced cholesterol gallstones. Methods: Eighty guinea pigs were randomly divided into normal control group, untreated group, YGLDG group and ursodeoxycholic acid (UDCA) group, with 20 guinea pigs in each group. Except the normal control group, gallstones were induced by high-cholesterol diet in the guinea pigs. The guinea pigs in the normal control group and the untreated group were administered with normal saline. UDCA and YGLDG were given to the guinea pigs in the corresponding groups for seven weeks. Eight guinea pigs of each group were used to measure the glucose infusion rate (GIR) by using hyperinsulinemic-euglycemic clamp technique. At the end the guinea pigs were killed and their gallstone formation was observed. Results: The gallstones in guinea pigs were identified as cholesterol stones by qualitative analysis through infrared spectrum. The incidence rate of cholelithiasis of the untreated group was 82.35% . The GIR of guinea pigs in the untreated group was obviously lowered down as compared with the normal control group. Compared with the untreated group, the GIRs of the YGLDG group and the UDCA group were obviously increased, especially in the YGLDG group. Conclusion: YGLDG may improve insulin resistance in guinea pigs with cholesterol gallstones by elevating GIR obviously.

AIM: To investigate the effect of VEGF gene transfer on matrix metalloproteinases(MMPs) and tissue inhibitor of metalloproteinases(TIMPs) expression after vascular balloon injury. METHODS: 90 New Zealand white rabbits were divided into 3 groups randomly: group Ⅰ(balloon injury group), groupⅡ (pAdtrackCMV group) and group Ⅲ(pAdtrackCMV-VEGF165 group). Hypercholesterol diet was given for 7 days before experiment and continued to receive until the animals were killed. Each group were divided into five subgroups according to the sacrifice time. Blood samples and iliac arteries were harvested for further analysis. RESULTS: In group Ⅰ and Ⅱ, MMP2 and TIMP1,2 expressions were detected during the whole process ,while in group III ,MMP1,2,9 and TIMP1,2 could be detected from 3 days after gene transfer and reached the highest level at 1 week and could not be detected at 8 week. CONCLUSIONS: Imbalance expression of MMPs and TIMPs occurred after vascular injury and this may be the reason of pathological remodeling. Local phAdtrackCMV-VEGF165 transfer could specifically change the expression of MMPs and facilitate the positive remodeling process after vascular injury.

ObjectiveTo explore the mechanism of extracorporeal shock wave (ESW) in treating osteogenic disorders and the ideal energy level. MethodsAfter success in marrow aspiration from patients' iliac crest, hMSCs were isolated by Percoll density gradient centrifugation and cultured in Dulbecco's modified Eagle's medium in a 5% CO2 and 37 ℃ incubator. Optimal ESW dose was determined by MTT of kinase-marked cytobiology. After hMSCs were exposed to ESW, their morphocytologic change, rate of adherence and doubling time were observed with IPCM. Enzyme cytochemistry reaction for the activity of alkaline phosphatase was also examined. ResultsESW of 5 kV and 100 times could increase cells' viability and proliferation (P<0.01), but higher than 7 kV would inhibit them. Rate of adherence of hMSCs in exposure group of passage 5 reached to 61.54%, which was significantly different from control group(P<0.05). Compared with control group, the MSCs' doubling time was short for 1.72 d (P<0.05). The curve of normal alkaline phosphatase activity of hMSCs was like type S, but ESW shortened its latent period, and promoted its peak time, which was significantly different from control group.ConclusionESW of 5 kV and 100 times can optimally promote the proliferation and activity of osteogen of hMSCs in vitro.
