Objective To evaluate the factors influencing the reproducibility and validity of food group intakes measured by a food frequency questionnaire (FFQ) for Chinese men. Methods A total of 214 adult men were randomly selected from the Shanghai Men Health Study (SMHS), an ongoing cohort study conducted in urban Shanghai. Each subject who had completed the first FFQ survey at recruitment took 24-hour dietary recall (24-HDR) surveys which were conducted once a month for 12 consecutive months and a second FFQ at the end of the study. Two FFQs were administered approximately 1.2 years apart. The food items listed in FFQ and obtained from 24-HDR were categorized into 11 food groups. The factors influencing the reproducibility of the FFQ was assessed by comparing the Pearson correlation of intake levels from the two FFQs, while the factors influencing the validity was evaluated by comparing intake levels from the second FFQ with the multiple 24-HDRs. Results A total of 195 men completed all 12 times of 24-HDR and twice FFQ surveys. The median Pearson correlation coefficients of the food groups between the two FFQs in older vs younger age group were 0.62 vs 0.50;in higher vs lower education level group were 0.58 vs 0.50;in higher vs lower income group were 0.51 vs 0.50;in higher vs lower BMI group were 0.50 vs 0.49. The median Pearson correlation coefficients of the food groups between the second FFQ and 24-HDRs in older vs younger age group were 0.61 vs 0.45;in higher vs lower education level group were 0.49 vs 0.47;in higher vs lower income group were 0.43 vs 0.57;in higher vs lower BMI group were 0.48 vs 0.51. Conclusions Age is the main factor influencing the reproducibility of the food group intakes by a FFQ used in the SMHS, while the factors influencing the validity are age and family income.

OBJECTIVE:To provide references for the revision of pharmaceutical talents training plan in higher vocational colleges. METHODS:Selecting parts of freshmen,sophomores and junior students majoring in pharmacy in our hospital as subjects, questionnaires were conducted for the effect of hospital“pharmacy trusteeship”policy on their employment selection,and the results were statistically analyzed. RESULTS:Totally 190,390,320 questionnaires were received from junior students,sophomores and freshmen. The surveyed students knew less about“pharmacy trusteeship”policy,only a maximum by junior students of 35.79%(comparison of different grades P<0.05);while among the surveyed students from different career directions,the highest awareness rate about“pharmacy trusteeship”policy was from the students whose hospital pharmacy(41.30%-45.21%)(comparison of different career direction P>0.05). The career direction of hospital pharmacy had the highest proportion of surveyed students in each grade(38.42%-53.13%),especially the freshmen(comparison of different grades P<0.05,comparison of different career direction in a same grade P<0.05). But after knowing the policy,the surveyed students had the lowest recognition for the original career direction,especially the junior students(64.38%)(comparison of different career direction P<0.05). The surveyed freshmen and sophomores were firstly concerned the stability and then the welfare and income of the job,the surveyed junior students were firstly concerned the welfare and income and then authorized strength and the stability of the job. CONCLUSIONS:The pharmacy trusteeship policy has not yet been fully implemented,its effect on employment selection of higher vocational students majoring in pharmacy is relatively backward and the deeper effects have not been appeared completely.

Objective: To explore the diagnostic value of combined detection of blood osteopontin (OPN) and matrix metalloproteinase-9 (MMP-9) for in-stent restenosis (ISR) in patients after percutaneous coronary intervention (PCI). Methods: A total of 142 patients who received post-PCI coronary angiography (CAG) in our hospital were studied. The patients were divided into 2 groups based on if there were ISR condition: ISR group,n=21and Non-ISR group,n=121. The blood levels of OPN and MMP-9 were detected upon the follow-up CAG conduction and the basic clinical information with biochemical indexes were compared between 2 groups. Results: Blood levels of OPN and MMP-9 were signiifcantly higher in ISR group than those in Non-ISR group,P<0.001. Multivariate logistic regression analysis revealed that elevated levels of OPN and MMP-9 were the independent risk factors for post-PCI ISR occurrence (OR=2.861 and OR=3.343,P<0.01). The ROC area of OPN and MMP-9 for predicting post-PCI ISR occurrence were 0.821 and 0.887,P<0.001. Taking the optimal cut off value of OPN at 3.68 ng/ml and MMP-9 at 415.24 ng/ml, the combined detection could increase the sensitivity of detection (90.48%) and the negative predictive value (98.06%). Conclusion: Blood levels of OPN and MMP-9 are closely related to ISR occurrence in post-PCI patients, combined detection has certain predictive value for ISR occurrence, especially for negative predictive value.

Objective To established a method for the determination of puerarin. Method The sample solutions were pretreated by solid phase extraction (SPE): the specimens were eluted and the cartridges saturated gradually by them in the SPE, but the strongly absorbed impurities were held by the cartridges all the same, and then the effluents were measured by HPLC. Results The linear range of puerarin was 0.205～ 2.464? g, r=0.9999. The average recovery of puerarin in Xintong Oral Liquid, Radix Purerariae and Ganmao Zhike Capsule were 99.5 % , 99.9 % and 98.5 % , RSD were 1.67 % , 1.45 % and 0.95 % (n=5) respectively. Conclusion The method is simple and accurate and can be used for the determination of puerarin in the Chinese patent medicines containing Radix Purerariae. 

Objective To establish a mouse model of aorta dissection (AD) by β-aminopropionitrile (BAPN) in drinking water + subcutaneously pumped angiotensin II (Ang II) infusion.Methods Forty 3-week-old C57B1/6J male mice were randomly divided into two groups.All animals received 0.1 g/kg/d BAPN in drinking water for 4 weeks.Then the BAPN drinking + saline infusion group and BAPN drinking + Ang II infusion group received continuous saline or Ang II (1,000 ng/kg/min) infusion, respectively, via subcutaneous osmotic minipump for 72 hour.The mice were restricted in a noninvasive computerized tail-cuff system and their arterial systolic blood pressure and heart rate were monitored.Autopsy was performed if a mouse died during the experiment.At the end of the experiment, mice were sacrificed by injection with an overdose of sodium pentobarbital and the aortas were harvested.The formation of aortic false lumen was observed by pathology using hematoxylin-eosin staining.Results The overall incidence of AD in the BAPN drinking administration +Ang II infusion group was 95%, whereas the incidence of AD in the BAPN drinking administration +saline infusion group was only 5%.The mortality from dissecting aneurysm rupture was 24% in the BAPN drinking administration +Ang II infusion group during the experiment.Pathological examination of the aortic cross-sections clearly showed the formation of blood-filled false lumens induced by Ang II.Conclusions A mouse model with high incidence of aortic dissection is successfully established.

Objective To investigate the therapeutic effects of endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic bile duct exploration lithotomy (LBDEL) in treatment of intra/extra-hepatic duct stones. Methods There were 110 patients whose intrahepatic stones located in Ⅰ , Ⅱ hepatic duct and 378 patients whose stones only located in the common bile duct. These patients respectively underwent LBDE combined with choledochoscope laser lithotripsy or ERCP combined with endoscopic sphincterotomy (EST) and endoscopic nasobiliary drainage (ENBD) to remove the stones. Common bile ducts were performed primary suture or T tube placement in the LBDEL cases. The evaluation was carried out for perioperative complications and postoperative recovery of the surgical methods. Results The residual stone rate was 31.82% in 110 cases. The rate was higher in ERCP group (51.06%) than that in LBDEL group (17.46%) (P < 0.05). Postoperative recovery was better in LBDEL group than that in ERCP group. The residual stone rate was 8.20% in 378 cases. The rate was lower in ERCP group (3.68%) than that in LBDEL group(11.63%) (P < 0.05). Between the two groups, there had no statistical significance in postoperative recovery. The incidences of bile leakage and pulmonary infection were higher in LBDEL group than in ERCP group. The incidences of abdominal cavity infection, acute pancreatitis, digestive tract perforation and gastrointestinal bleeding were higher in ERCP group than that in LBDEL group. 2 of the 378 patients occurred death were happened digestive tract perforation which were induced during ERCP procedure. Conclusion LBDEL and ERCP demonstrated the same therapeutic effects in the treatment of common bile duct stones. However, ERCP has no large advantages in the treatment of hepatolithiasis, and shows higher complication rates. LBDEL has a significant curative effect for intra-and extrahepatic bile duct calculi and can maintain the integrity of Oddi sphincter. This technology is easy to spread to the basic-level hospital to benefit the majority of patients.

Insulin resistance in insulin sensitive organ results in metabolic disorder such as hyperglycemia, hyperinsulinemia and hyper triglyceridemia which are common features of type 2 diabetes.Insulin resistance in liver cells mainly causes impaired glycogen synthesis, failed to suppress glucose production which is the major contribution to hyperglycemia.FGF-21 as a new metabolic regulator can control fasting blood glucose.The mechanism of FGF-21 effects on regulating plasma glucose has little to known.In order to establish an in vitro insulin resistant model of liver cells and evaluate the effects and mechanism of FGF-21 on glucose metabolism in the cell model, HepG2 cells were incubated with 10-7 mol/L insulin for 24 h to build insulin-resistant cell model.To evaluate the cells for insulin resistance, the cells were stimulated with fresh insulin for 24 h and the glucose uptake by these cells was carried out.The insulin-resistant cells were treated with different concentrations of FGF-21 for 24 h and insulin-treated cells were used as a control.The glucose uptake by the cells was detected by the method of glucose oxidizes/peroxides(GOD-POD);the synergy between insulin and FGF-21 was evaluated.The mRNA expression of GLUT1 in the insulin-resistant cells was detected by the real-time PCR.Glycogen synthesis of the cells was examined by the anthrone method.The results showed that HepG2 cells treated with 10-7 mol/L insulin for 24 h became resistant to insulin and the insulin resistance status was maintained for 48 h without change of cell morphology.FGF-21 could stimulate glucose consumption of the insulin-resistant model in a dose-dependent manner.The glucose consumption and glycogen synthesis of the insulin-resistant model were significantly improved by FGF-21 treatment.FGF-21 showed strong synergy with insulin in glucose uptake and glycogen synthesis of the model cells.While the cells became resistant to insulin, FGF-21 could increase the mRNA expression of GLUT1.Thus, It is concluded that FGF-21 stimulates glucose uptake in insulin resistant HepG2 cells through GLUT1 expression, stimulates glycogen synthesis and improves the glucose metabolism in the insulin resistant liver cell model.
