1.Analysis of protoscoleces-specific antigens from Echinococcus granulosus with proteomics combined with Western blot.
Biomedical and Environmental Sciences 2012;25(6):718-723
OBJECTIVETo establish and optimize the proteomic analysis of protoscoleces-specific antigens from Echinococcus granulosus. To provide a foundation for identifying specific antigens in the soluble proteins of E. granulosus protoscoleces for further research.
METHODSBrood capsules were collected aseptically from fertile E. granulosus cysts from the livers of an infected patient. The fertile E. granulosus cysts were fractured, and protoscoleces were collected by centrifugation. The soluble proteins of protoscoleces were acquired using the 2D Quant kit according to the manufacturer's instructions. We employed two-dimensional electrophoresis (2-DE) combined with immunoblot assay (Western blot) to analyze the soluble components of E. granulosus protoscoleces antigens. The 2-DE and immunoblot maps obtained were analyzed with PDQuest 8.0 image analysis software.
RESULTSAbout 233 soluble protein spots were identified with Coomassie-stained gels. Most of the proteins had a molecular weight of 16,000 Da to 117,000 Da, and an isoelectric point value of 3.0 to 10.0. 2-DE immunoblot was conducted and 57 specific antigen spots were observed, among which 23 spots were identified.
CONCLUSION2-DE combined with Western blot is the key to successful proteomic analysis and presents a new possibility for searching the specific E. granulosus protoscoleces antigens.

6. Analysis of drug-drug interactions in prescriptions for hospitalized diabetic patients
Chinese Pharmaceutical Journal 2014;49(11):944-947
OBJECTIVE: To evaluate the types and prevalence of potential drug-drug interactions (DDIs) in the prescriptions for diabetic patients hospitalized in the department of endocrinology from March 2012 to February 2013, classify the DDIs as per pharmacotherapeutic class of medications and investigate the relationship between medication classes and frequency of potential DDIs, in order to provide basis for management of medication therapy. METHODS: The prescriptions were checked for drug interactions by clinical pharmacists with the support of hospital drug information system. RESULTS: Prescriptions for total of 450 diabetic patients were collected. The average HbA1C before hospitalization was (9.4±2.4)%. The average duration of diabetes was(11.0±8.1)years. The most common regimen was insulin therapy, followed by combination therapy of insulin and alpha glucosidase inhibitors. The most common DDIs occured between aspirin and β-blockers. CONCLUSION: The patients are at risk of potential DDIs. An appropriate surveillance system for monitoring such interactions should be implemented. Physicians should be more aware of potentially harmful DDIs. Pharmacists can contribute to the detection and prevention of drug-related injuries, especially of clinically meaningful DDIs that pose potential risks to patient safety.
7. Evaluation of the rationality and safety of Shuxuening injection in 212 outpatients
Chinese Pharmaceutical Journal 2014;49(1):76-79
OBJECTIVE: To investigate the rationality and safety of Shuxuening injection used in our hospital. METHODS: Two hundred and twelve outpatients (77 males, 135 females) were selected. Survey forms designed for this research were filled in with items including age, sex, clinical diagnosis, symptom, dosage, course of treatment, adverse reactions due to the injection and outcome. Data were analyzed statistically. RESULTS: For the 212 cases with an average age of (59.8±12.8) yeas, the average dose of Shuxuening injection was 20 mL, given once daily by intravenous infusion; the duration of therapy was (7.5±3.2) d; the rate of adverse reactions was 5.66%. CONCLUSION: Shuxuening injection is used rationally in our hospital, and it is generally safe when used according to the labeling.

ObjectiveTo investigate the development of apoptosis during ischemia/reperfusion (IR) injury and acute rejection, and to explore the significance of apoptosis in the Graft Mesenteric Lymph Node (GALT) in a rat heterotopic small bowel transplant (SBT) model.MethodsSBT was performed in F344/N rats with either freshly harvested or preserved (4 h, in ringer lactate solution at 4 ℃) syngeneic and allogeneic (Wistar/A-F344/N) grafts. Bowel and GALT samples were collected 2 h after reperfusion and on small bowel transplant postoperative days (POD) 1, 4, and 7. Histopathology assessment of the graft and GALT were prepared for hematoxylin-eosin (H&E) staining. Apoptosis was detected by the TUNEL and the electron microscope. ResultsThe number of apoptotic cells 2 h after reperfusion increased profoundly in association with preservation. After a significant decrease on POD 1, the apoptotic cells rose again between POD 3 and 7 only in allogeneic grafts. On the other hand, the apoptotic cells in allogeneic GLAT markedly increased from POD 1 to day 3; at that time point, neither histological findings of rejection nor increase in apoptotic crypt cells were present in the graft jejunum. ConclusionIR injury and acute rejection may both induce extensive apoptosis. The graft jejunum distinct second increase in apoptosis may be an early and specific sign of acute rejection. Apoptosis of GLAT cells was well correlated with and ahead of progression of acute rejection.

OBJECTIVETo investigate the clinical effects of enblock distal radius T-plate fixation in treating trailing edge fracture of tibial plateau medial condyle and posterior cruciate ligament (PCL) avulsion fracture.
METHODSFrom September 2008 to November 2011, 5 patients with trailing edge fracture of tibial plateau medial condyle and PCL avulsion fracture caused by knee joint hyperextension,were treated with surgery. There were 3 males and 2 females with an average age of 35 years old (25 to 42). Left knee injury was in 3 cases and right knee had in 2 cases; 2 cases caused by sports injury and 3 cases caused by road accident. All patients were undergone emergency treatment. Fractures were anatomically reduced and fixed with T-plate through poples approach. Complications were observed after operation. Bone healing and clinical effects were respectively evaluated by X-rays and HSS system.
RESULTSFive patients were followed up for 1 to 4 years with a mean of 2 years. All incisions obtained healing of I stage. All knee joints recovered well and were stable with inflexion more than 120 degrees, no complications such as knee joint pain, injuries of nerve and blood vessel, infection, internal fixation failure were found. The mean score of HSS system was 94.40 +/- 6.09 and all patients got excellent result.
CONCLUSIONFor the treatment of trailing edge fracture of tibial plateau medial condyle and PCL avulsion fracture caused by knee joint hyperextension, enblock distal radius T-plate fixation had advantages of good stability,higher success rate, and knee joint function can recover well.

Objective To study the differences in clinical characteristics and etiology in bronchopneumonia and lobar pneumonia,and provide the basis for the clinical diagnosis and treatment.Methods A retrospective study was performed on 100 children with lobar pneumonia and 200 children with bronchopneumonia from Dec.2005 to Dec.2007.Antibodies of mycoplasma(MP) and chlamydia(CP) were detected with quantitative enzyme linked immunosorbent assay of serum samples which were collected on addmission.On the second day morning,axenic sputum samples of laryngeapharyngis at pars were collected with onetime asepsis aspiration sputum tube by negative pressure for bacterial culture,and the common seven viruses were detected with direct immunofluorescence,and MP DNA,CP DNA were detected.The results and the clinical data and the characters of sternum were analyzed.Results Lobar pneumonia was more in the elder children,and the features were fever and cough in clinic,absence in physical sign of bellow,and inflammation of one pulmonary lobe in X-ray.Sixty-one percent of childhood lobar pneumonia had MP infection in laboratory examination.But bronchopneumonia was found more in infants and young children,whose features were cough,dyspnea and catarrhus in clinics,wheezy phlegm and stridor in physical sign of bellow,pulmonic shadow of spot and lamellar in X-ray.Bacteria were the most common pathogen in bronchopneumonia.Conclusions Lobar pneumonia was different from bronchopneumonia in age and clinic features and sternum characters of patients,and much more different in etiology.Bacterial infection was important in bronchopneumonia.But in lobar pneumonia,MP infection occupied 61.0%,which was different from traditionaletiology.Moreover,the MP infection rate in infant and young children tend to increase obviously.
