OBJECTIVE:To evaluate the human body pharmacokinetics and bioequiavailability of two kinds of oral single dose of hydrochloric itraconazole capsules.METHODS:A randomized,crossover study of20healthy volunteers receiving sin-gle oral dose of200mg itraconazole was conducted with in vivo blood concentrations determined by HPLC-fluorescence de-tection.RESULTS:The pharmacokinetic parameters for the testing itraconazole and the reference itraconazole were as fol-lows,t 1/2 were(29.3?5.62)h and(29.3?5.81)h,respectively;C max were(81.4?60.0)?g/L and(77.8?45.2)?g/L,respec-tively;t max were(3.9?0.70)h and(4.2?0.70)h,respectively;AUC 0～72 were(1199.4?649.6)(?g?h)/L and(1174.3?701.9)(?g?h)/L,respectively;AUC 0～∞ were(1414.0?815.2)(?g?h)/L and(1386.1?735.8)(?g?h)/L,respectively.there were no significant differences in main pharmacokinetics parameters between2preparations,except in t max from analysis of variance and one-side&two-sides t-tests.The relative bioavailability of trial itraconazole capsule was(105.3?23.4)%.CONCLUSION:These two kinds of itraconazole capsules are bioequivalent.

OBJECTIVETo analyze the changes of patients with type 2 diabetes in different stages in glucagon (GC) and free fatty acid (FFA) in fasting, OGT and L-Arg experiments, and discusses the role of pancreatic alphabeta cells in diabetes pathogenesis by studying the relations among indexes such as glucagon (GC), free fatty acid (FFA) and blood glucose (BG), insulin, insulin homeostasis model (HOMA) and glucose metabolism hormone secretion curve, in order to provide theoretical basis for the treatment of diabetes.

METHODStudy objects were divided into the T2DM group (45 cases), the IGT group (28 cases) and the NGT group (30 cases) for an OGTT experiment and then an L-Arg experiment on the next day. Under the fasting state, their blood glucose (FBG), insulin (F), glucagon (FGC), free fatty acid (FFA) were detected to calculate HOMA-beta, insulin sensitivity index (ISI) and HOMA-IR of different groups. Meanwhile, efforts were made to calculate different time quantum detected in OGTT and L-Arg experiments and area under the curve AUC(BG), AUC(INS) and AUC(GC).

RESULTObvious overall differences were observed in FFA and FGC of the three groups. FGC of each group was negatively correlated with HOMA-beta and ISI. Among all of the 103 study objects, FGC was positively correlated with FBG and HOMA-IR and negatively correlated with HOMA-beta and ISI, with no correlation with FINS; FFA was positively correlated with FBG, HOMA-IR and negatively correlated with FINS, HOMA-beta, ISI. FGC and FFA were positively correlated in the T2DM group and the IGT group, but with no statistical correlation in the NGT group. The sequence of the three study objects was T2DM > IGR > NGT in AUC(GC) in the OGTT experiment and T2DM > IGR > NGT in in AUC(GC) in the L-Arg experiment, with the significant positive correlation between AUC(GC) and AUC(BG) and significant negative correlation with AUC(INS).

CONCLUSIONGlucagon and free fatty acid of T2DM and IGT patients increased, which was positively correlated with blood glucose and HOMA-IR and negatively correlated with INS, HOMA-beta and ISI. The increase in glucagons of T2DM and IGT patients indicated inappropriate secretion of pancreatic alphabeta cells among patients with type 2 diabetes.

Objective To investigate the prevalence of clonorchiasis among residents of Huachuan Country,Heilongjiang Province and to provide a basis for development of control strategies.Methods From 2011 to 2012,cluster random sampling was performed to survey the incidence of clonorchiasis in Huachuan Country.Fecal specimens were collected and examined the clonorchis sinensis eggs by Kato-Katz method.A questionnaire survey was conducted to collect related information such as age,gender,occupation and eating habits.The infection characteristic was analyzed.Results Totally 884 patients with clonorchiasis were found among 2248 residents,and the infection rate was 39.32％.The infection rate in male[47.15％(611/1296)] was significantly higher than females [28.68％(273/952),x2 =34.55,P ＜ 0.01].The infection rate increased with age,which was higher in the 20-69 years old people,with the highest infection rate in the 50-59 years old groups[45.34％ (219/483)].Of the occupational distribution,farmers had the highest infection rate [47.24％ (420/889)],followed by cadres and staffs[38.38％(190/495)].Of residents with fresh fish eating history,the prevalence of clonorchiasis was 53.38％(150/281).Conclusions The prevalence of clonorchiasis is still high in Huachuan County.To reduce the prevalence of clonorchiasis,comprehensive prevention measures,health education and group chemotherapy should be carried out.

Objective To evaluate the effectiveness of bioelectrical impedance analysis(BIA) interventions on volume status in hemodialysis patient. Methods Searched The Cochrane Library, PubMed, EMbase, EBsco, Wanfang Data, China Biology Medicine, China National Knowledge Infrastructure to collect clinical trials. The retrieval time was from database to July 15, 2016. The studies were selected according to the inclusion and exclusion criteria and were critically appraised by two reviewers. Then the data of included studies were extracted. Meta-analysis was conducted by using RevMan 5.3 software and descriptive analysis. Results Ten clinical trials were included six random control trial, one controlled clinical trail, three longitudinal study, involving 2009 patients. The results of Meta-analysis showed that the effectiveness of BIA interventions on volume management could improve blood pressure (P=0.001), protect the heart function(left ventricular mass index,P=0.002), compared with the clinical evaluation method, the BIA assessment of dry weight of hemodialysis patients could reduce hospitalization rate 14%. Descriptive analysis showed that BIA intervention volume management had certain advantages for the survival benefit of patients, but the current research was still few, had not yet come to a certain conclusion. Conclusions BIA can improve the management of the volume status and dry weight of hemodialysis patients, so as to it can improve the clinical benefit and survival benefit of patients.Better methods and guidelines for assessing DW and using BIA need to be developed.We propose that experienced HD nursing staff be trained in the use of the BIA to help monitor patient over hydration and approximate dry weight in consultation with the nephrologists responsible for the care of these patients so as to obviate excessive residual over hydration between nephrology reviews.

Aim at the two problems in the field of traditional Chinese medicine (TCM) mechanism elucidation, one is the lack of detailed biological processes information, next is the low efficient in constructing network models, we constructed an auxiliary elucidation system for the TCM mechanism and realize the automatic establishment of biological network model. This study used the Entity Grammar Systems (EGS) as the theoretical framework, integrated the data of formulae, herbs, chemical components, targets of component, biological reactions, signaling pathways and disease related proteins, established the formal models, wrote the reasoning engine, constructed the auxiliary elucidation system for the TCM mechanism elucidation. The platform provides an automatic modeling method for biological network model of TCM mechanism. It would be benefit to perform the in-depth research on TCM theory of natures and combination and provides the scientific references for R&D of TCM.

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.

METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).

RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.

CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

This retrospective analysis compared standard regimen of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) with the dose-dense ABVD regimen (ABVD-21) in terms of efficacy and toxicity. Patients who had early-stage unfavorable or advanced Hodgkin's lymphoma (HL) according to German Hodgkin Study Group criteria from March 1999 to February 2011 were analyzed for treatment response, long-term survival and hematological toxicity. There were 85 patients in the ABVD-21 group and 118 patients in the ABVD group respectively. The complete remission rates after completion of treatment were 92.9% and 90.7% for ABVD-21 and ABVD, respectively. During a median follow-up period of 62 months, no significant difference was found in projected 10-year progression-free survival (PFS) and overall survival (OS) rates (84.7% and 94.1% respectively for ABVD-21; 81.4% and 91.5% for ABVD). Subgroup analyses showed that ABVD-21 was significantly better than ABVD for patients with IPS≥3 in terms of PFS and OS rates. Grade 3 to 4 leukopenia (51.8% vs. 28.8%, P=0.001) and neutropenia (57.6% vs. 39.0%, P=0.009) were more common with ABVD-21. We were led to conclude that dose-dense ABVD did not result in better tumor control and overall survival than did ABVD for early-stage unfavorable HL. However, patients at high risk, for example, with IPS≥3, may benefit from dose-dense ABVD.

Solid dispersions technique was used to solidify buagafuran and improve buagafuran in vitro dissolution and stability. Buagafuran solid dispersions were prepared separately using PVPK30, PEG6000 and Poloxamer188 at various weight ratios as carriers. The status of buagafuran in solid dispersions was determined by using DSC and IR. The solubility, content and in vitro dissolution of pure drug and the solid dispersions were detected by using HPLC. When buagafuran/carrier was 1:5 or less, the drug existed in a solid dispersion form. Three kinds of carriers all can improve buagafuran dispersibility and in vitro dissolution. Accelerating experiment showed that buagafuran/PVPK30 < or = 1:10 solid dispersions was ageing-resistant, and the aspect, content and in vitro dissolution did not change after storaged over 3 months, but PEG6000, Poloxamer188 and a lower ratio PVPK30 solid dispersions became aged. Buagafuran/PVPK30 < or = 1:10 solid dispersions can be developed as buagafuran oral drug delivery carrier.
