AIM　To develop a method for the determination of trimebutine maleate in rat plasma by using high performance capillary electrophoresis. The method was employed to pharmacokinetic analysis of trimebutine maleate. METHODS　Plasma samples were deproteinized with acetonitrile (containing ephedrine hydrochloride as internal standard) and the supernatant was dried under N2 stream at 50℃. The residue was dissolved with methanol-water (1∶1) and injected into the capillary by siphon. The electrophoresis was performed in uncoated fused-silica capillary and the voltage was 10 kV. The running buffer was 0.03 mol*L-1 NaH2PO4 (pH 6.0). The eluate was detected at 214 nm by UV detection. RESULTS　The recovery for trimebutine maleate in rat plasma was 72.8%-87.9%. The calibration curve in plasma was linear over the range 5-200 μg*L-1. The limit of quantitation was 5 μg*L-1. The intraday relative standard deviation (n=6) and the interday relative standard deviation (n=18) were less than 14%. The highest concentration in plasma was observed at 30 min after ig trimebutine maleate to rats. The pharmacokinetic results were AUC0-∞=8 μg*min*mL-1, T1/2(Ke)=173 min and Ke=5.6×10-3 min-1. CONCLUSION　The method is accurate, sensitive and suitable for pharmacokinetic study of trimebutine maleate.

Objective To analyze the composing principles of the prescriptions for Lijie disease by using The Prescription of Traditional Chinese Medicine Dictionary. Methods The prescriptions for Lijie disease in the book of The Prescription of Traditional Chinese Medicine Dictionary were collected. Database was established by using TCM Inheritance Support System (V1.1). Medicine using frequency, composing principles, and composition of new medicine were analyzed through association rules and entropy clustering method. Results Based on the analysis on 187 cases of prescriptions, 42 Chinese herbal medicines were with the frequency of 42 times and Angelicae Sinensis Radix was the core herbal medicine. 69 core combinations with three to four herbal medicines and 6 new prescriptions were obtained through evolution. Conclusion According to the analysis of composing principles and clustering new prescriptions of Lijie disease, the treatment for Lijie disease is toning liver and spleen, and nourishing liver and kidney.

In high-risk patients,such as patients with hematologic malignancies,or patients after allogeneic stem-cell or solid-organ transplantation,early diagnosis of invasive aspergillosis(IA) is essential,as missing or delayed diagnosis of IA results in increasing rates of mortality.However,diagnosis of IA is difficult because classic tests have low sensitivity and specificity.The limited sensitivity and specificity of conventional assays for the detection of IA and the growing number of IA patients have led to the development of new assays.These methods include antigen detection systems,such as galactomannan(GM) assay,and different molecular methods(PCR assays).The GM assay is commercially available.However,it still need to be evaluated in large patient cohorts,especially children.A range of different PCR assays have been developed,targeting different gene regions,including a variety of amplicon detection methods.These molecular assays provide high potential in terms of sensitivity and specificity,but vary widely in their feasibility and up to now have not been standardised.Taken together,new non-culture-based diagnostic assays are noninvasive,simple,rapid and highly sensitive.Thus,they might be valuable tools to make early diagonosis,to reduce empirical antifungal therapy and to monitor the therapy.

Interstitial brachytherapy with radionuclide seeds has been successfully used for the treatment of cancer. But there are some problems remain to be solved. This review focus on some recent advances in the study of brachytherapy, including the option of radionuclides, the influence of dosage distribution by using different sources, the quality assurance, the application of brachytherapy in hollow visceral neoplasm,and new trends in brachytherapy.

Objective To evaluate the mucosal microvascular morphological changes in superficial nasopharyngeal carcinoma (NPC) and its clinical value under narrow band imaging (NBI).Methods From 2015.01 to 2016.01, 182 patients at high risk for NPC received biopsy of superficial nasopharyngeal lesions due to the existence of irregular vessel under NBI while they were examined with electronic nasopharyngolaryngoscope quipped with white light mode and NBI mode. Compared the mucosal microvascular morphological characteristics of different diseases based on pathological result and evaluated the diagnostic efifcacy of NBI.Result Under NBI, the mucosal microvascular morphological characteristics of nasopharyngeal carcinoma under NBI mode were of that concentrated brown spots (CBS, 38.24 %) and irregularly dilated branching vessels (IDBV, 41.18 %) with demarcation line (DL, 52.94 %). In addition, IDBV were the main microvascular pattern in fresh NPC cases (57.89 %,P = 0.000), while CBS were the main microvascular pattern in post-radiation local recurrent NPC cases (60.00 %,P = 0.000). The sensitivity, speciifcity, positive predictive value, negative predictive values and diagnostic coincidence rate of NBI in NPC screening were 79.41 %, 95.95 %, 81.82 %, 95.30 % and 92.86 %, respectively.Conclusion NBI endoscopy is a promising tool for improving the early diagnosis of NPC by detecting mucosal microvascular morphological changes in superifcial NPC.

OBJECTIVE:To provide suggestions for retail drugstores on how to tackle problems of non-quality induced drug returning from customers.METHODS:Reasons why it is hard to return the already purchased drugs were analyzed based on the status quo of drug returning in retail drugstores,and some countermeasures were presented on how to reduce or avoid non-quality induced drug returning problems.RESULTS&CONCLUSION:Non-quality induced drug returning problems can be well solved in drugstores through improving pharmaceutical care level and management level.

OBJECTIVE:To provide the reference for drug stores to choose the chain mode:the direct sales or franchise.METHODS:The common modes of the drug store’chain administration and the current condition of the chain drug store industry in china were summarized;The merits&demerits of each mode and the environment,which influenced the choice of chain modes,were analyzed.RESULTS&CONCLUSION:The phenomenon can not be the proof that direct sales are better than the franchise in the market.The Chinese pharmaceutical chain enterprises should make their own choices based on the specific situation.The improved franchise mode is very competitive in the market.

Objective To study the action of death signal receptor pathway of apoptosis in the development of gallbladder carcinoma . Methods Streptavidin biotin peroxidase immunohistochemistry technique was used to study the expression of Fas L in gallbladder carcinoma tissues,and TUNEL method for in situ detection of the number of apoptotic infiltrating lymphocytes around the tumor. Results The positive rates of Fas L in gallbladder carcinoma , gallbladder adenoma, dysplasia of gallbladder epithelium and chronic cholecystis were 84.6%(22/26), 83.3%(15/18) ,100%(3/3) and 55%(11/20), respectively. The positive rate of Fas L in gallbladder carcinoma was significantly higher than in chronic cholecystis (P

Objective To investigate therapeutic efficiency of high frequency electric therapy combined with movement training on osteoarthritis of knee joint.Methods Eighty-five patients were randomly divided into the high frequency electric therapy group (22 cases including 31 knees), movement training group (33 cases including 45 knees) and high frequency electric therapy combined with movement training group (30 cases including 40 knees). All of the patients were assessed with Visual Analogous Scale (VAS) and Lysholm Knee Score Scale (LKSS) before and after treatment.Results Every group had significant improvements compared with selves after treatment. There were significant differences among the three groups (P<0.01).Conclusion Three ways have different therapeutic effect on osteoarthritis of knee, the high frequency electric therapy can slacken the soft tissue, the movement training has reliable effect in the near future; the therapy by high frequency electric therapy combined with movement training is reliable.
