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 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 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 investigate the protective effect of icariin against varicocele-induced damage on rat epididymis. Methods Forty adolescent male SD rats were randomly divided into control group (n=10), experimental varicocele (EV) group (n=15), icariin (ICA) therapy group (n=15). Experimental varicocele model in the EV group and ICA group was established. The EV was induced by partial ligation of the left renal vein. The rats in the control group underwent a sham operation that separated the spermatic vessels without ligation. Each rat in the control group and EV group was lavaged with 2 mL physiological saline every day for 6 weeks. Each rat in the ICA group was lavaged with icariin [100 mg/(kg·d)] for 6 weeks. Rats in all groups were executed after 6 weeks. The contents of sialic acid were measured by spectrophotometry. Carnitine concentrations were measured by DTNB. HE stain was used to observe the microstructure changes in the epididymal tissue. Electron microscopy was used for observing the ultrastructural changes of the epididymis. Terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) method was used to detect the apoptosis of the epididymal epithelium. Results Compared with the control group, the microstructure and ultrastructure of the epididymis in EV group showed pathological damage. Compared with the EV group, the damage of the epididymal microstructure and ultrastructure significantly alleviated. Apoptosis index (AI) of epididymal epithelium in the EV group was significantly higher than that in the control group (P<0.01). However, AI of epididymal epithelium in the ICA group was significantly lower than that in the EV group (P < 0.01). The sialic acid and carnitine concentrations of the epididymis in the EV group was significantly lower than that in the control group (P < 0.01), respectively. However, the sialic acid and carnitine concentrations of the epididymis in the ICA group was significantly higher than that in the EV group (P < 0.01), respectively. Conclusion This study indicates that varicocele could result in the apoptosis of epididymal epithelium and icariin decreased the varicocele-induced apoptosis , suggesting that varicocele could damage the structure and function of epididymis, which can be repaired by icariin.

Objective To study the distribution of Candida infection and drug tolerance in intensive care unit(ICU). Methods A retrospective study was conducted. The critical patients admitted from January 2011 to December 2013 in ICU of the First Hospital of Jiaxing in Zhejiang Province were enrolled,and their clinical data with positive Candida culture and drug susceptibility results in specimens of sputum,urine,blood,ascites,bile, etc were collected. In the study of these 3 years in ICU,the situation of Candida infection,the distribution of positive specimen,the condition of distribution of different strains of Candida,and the Candida tolerance to antifungal drugs were analyzed. Results From 2011 to 2013,2 412 times of patients(including one patient had admitted into ICU for more than one time)were admitted into ICU in which 407 cases were of Candida infection(16.9%),and the rate of Candida infection was rising gradually in the 3 years〔2011 to 2013 Candida positive rates were 13.4%(77/573), 16.1%(146/907),19.7%(184/932)〕,the difference being statistically significant(P<0.01). In the 407 strains of Candida,166 strains(40.8%)were isolated from sputum,157(38.6%)from urine,53 strains(13.0%)ascites, 13 strains(3.1%)blood,11 strains(2.7%)bile,7 strains(1.7%)from other specimens. The strain distribution of Candida was mainly as follows:Candida albicans(174 strains),Candida glabrata(131 strains),Candida tropicalis (83 strains),Candida parapailosis(5 strains),Candida krusei(12 strains),and 2 strains of rare Candida portugal and Lipolztica. From 2011 to 2013,the highest tolerance of Candida albicans,Candida glabrata,Candida tropicalis to fluconazole,itraconazole,Fushita Yasu and other antifungal drugs was in 2013,and the lowest was in 2012,the rates of tolerance of the above 3 strains of Candida to amphotericin B being 0,to itraconazole being the highest(10.9%, 27.8%,9.6%,respectively),to Fushita Yasu the secondary(6.6%,11.0%,0,respectively)and to fluconazole the last(4.7%,7.4%,1.9%,respectively),and the rates of tolerance of Candida parapsilosis,Candida krusei,Candida Portugal,Candida lipolztica to amphotericin B,fluconazole,itraconazole,Fushita Yasu were all 0. Conclusion In ICU,the Candida infection is mainly in the respiratory tract and urinary tract,its rate of infection has a tendency of rising,and the rate of Candida tolerance to itraconazole is the highest.
