OBJECTIVE:To offer guidance for pharmacy work and provide references for rational use of traditional Chinese medicines. METHODS: 3 425 outpatient prescriptions of traditional Chinese medicines in our hospital in 2006 were randomly collected for the analysis of the drug use pattern by tabulation method. RESULTS & CONCLUSION: The use of traditional Chinese medicines prescribed in our hospital was rational on the whole, but the prescriptions of traditional Chinese medicines for diseases of respiratory system were on the high side, and the diagnoses in the prescriptions were more like the diagnoses of west medicines but lacked the characteristics of traditional Chinese medicine, so that the international classification coding of disease was not suitable for traditional Chinese medicine. Medication frequency of traditional Chinese medicines serves as guidance for the dispensary of traditional Chinese medicine. The hospital information system is far from perfect.

Objective To discuss combined detection of pleural biopsy under medical thoracoscopy and pulmonary serum tumor markers in diagnosis of pleural effusion with unknown reason.Methods 76 patients with pleural effusion caused by unknown reason from January 2014 to March 2016 were retrospectively analyzed. Pleural biopsy was conducted under medical thoracoscopy and sent for pathological examination, and 10 ml venous blood was collected from these patients upon admission for testing serum tumor markers (CEA, SCC-AG, ProGRP and CYFRA21-1).Results Among the 76 patients, there were 32 cases with benign lesions (14 with pulmonary tuberculosis, 9 with inlfammatory lesions, 6 with granulomatous inlfammation, 2 with empyema and 1 with hamartoma) and 44 cases with malignant lesions (18 with adenocarcinoma, 13 with squamous carcinoma, 6 with small cell lung cancer, 3 with adeno-squamous carcinoma, 2 with mesothelioma, 1 with large cell carcinoma and 1 with thymoma). The detection of serum tumor markers showed statistically significant differences in the levels of CEA, SCC-AG, ProGRP and CYFRA21-1 in serum between the malignant pleural effusion group and benign pleural effusion group (P = 0.021,P = 0.006,P = 0.003 andP = 0.010). The levels of various serum tumor markers in the malignant pleural effusion group were obviously higher than those in the benign pleural effusion group. According to the pathological results, patients with pleural effusions not caused by lung cancer (2 with mesothelioma and 1 with thymoma) were eliminated from 44 patients with malignant pleural effusions. The rest 41 patients with pleural effusions caused by lung cancer were divided into non-small cell lung cancer and small cell lung cancer according to the pathological types. The results showed that there were statistically signiifcant differences in the levels of CEA, ProGRP and CYFRA21-1 between non-small cell lung cancer and small cell lung cancer (P = 0.036,P = 0.005 andP = 0.008), while there was no statistically signiifcant difference in the level of SCC-AG (P = 0.811).Conclusions Due to high detection rate and high accuracy in detecting pleural effusions caused by unknown reason, medical thoracoscopy is of great signiifcance, especially for the diagnosis of malignant pleural effusions of pleural metastases. However, serum indicators may provide important reference values for us before the pathological results are available. Thus, it is an important means of diagnosing malignant pleural effusions caused by lung cancer and should be promoted in clinic.

Objective:To compare the clinical effect and safety of three different regimens treating children with severe pneumonia.Methods:120 cases treated in our hospital from January,2012 to January,2016 were randomly divided into the observation group 1 (dopamine combined with dobutamine,42 cases),observation group 2 (dopamine combined with phentolamine,40 cases),control group (38 cases).The clinical effect and levels of inflammatory cytokine were compared between the three groups.Results:The total effective rate in the observation group 1 was 90.48％ and that of observation group 2 was 87.5％,which were significantly higher than that of the control group (63.16％).The disappearance time of pulmonary rales,cough,dyspnea,pyretolysis and length of stay in the observation group (both 1,2) were significantly shorter than those of the control group (p ＜0.05).After therapy,the level of serum IL-6,IL-8,CRP and TNF-α in all the three groups were obviously decreased compared with those of before therapy (p＜0.05),and those of the observation group were significantly lower than the control group (p ＜ 0.05).Conclusion:Dopamine combined with dobutamine as well as dopamine combined with phentolamine were both effective methods in treating children with severe pneumonia,which were significantly better than conventional therapy.

Objective To analyse the femoral head coverage rate of CT in evaluation of Salter osteotomy for developmental dislocation of hip(DDH) in children. Methods Thirty-eight patients with unilateral DDH for Salter osteotomy were enrolled,and X ray photography of pelvis and spiral CT scanning of femoral articulation were performed one week before and 6 months after Salter osteotomy.The femoral head coverage rate of X ray and that of CT were calculated and compared.Another 38 children with normal femoral articulation were served as controls. Results The femoral head coverage rate of X ray was significantly higher than that of CT in patients with DDH(P

Objective To test whether the changes of partial end-tidal carbon dioxide pressure (PETCO2) during passive leg raising (PLR) predict fluid responsiveness in mechanically ventilated patients with septic shock.Methods Forty-two mechanically ventilated patients with septic shock admitted from January 2012 to November 2012 were prospectively recruited.Hemodynamic parameters monitored by a pulse indicator continuous cardiac output(PiCCO) device and PETCO2 monitored by an expiratory-CO2 device were studied at baseline,after PLR,and after volume expansion.Fluid responsiveness was defined as an increase in cardiac index (CI) of 15％ or greater after volume expansion.The correlation between PLR-induced CI change (△CIPLR) and PETCO2 (△PETCO2-PLR) was analyzed.The value of △PETCO2-PLR to predict fluid responsiveness was evaluated by receiver operating characteristic (ROC) curves.Results A total of 42 patients were enrolled in this study,of whom,24 had a CI increase of ≥ 15％ after volume expansion (responders).After PLR,CI and PETCO2 were both significantly increased in the response group compared with baseline [(21.4 ± 12.9) ％ of CI and (9.6 ± 4.7) ％ of PETCO2,P ＜ 0.05],while no significant changes were observed (P ＞ 0.05) in the non-response group.Both △CIPLR and △PETCO2-PLR were significantly higher in responder group than in the non-responder group (both P ＜ 0.05).△CI and △PETCO2 after PLR were strongly correlated (r =0.64,P ＜ 0.05).In responders after PLR,the area under ROC curve of △PETCO2-PLR was 0.900 ± 0.056 (95％ CI 0.775-1.000,P ＜ 0.05).An increase of ≥ 5％ in △PETCO2-PLR predicted fluid responsiveness with a sensitivity of 88.0％ and specificity of 88.2％.Conclusions The change of PETCO2 induced by passive leg raising is a non-invasive and easy way to predict fluid responsiveness in mechanically ventilated patients with septic shock.

Puerarin (PUE), as an isoflavone component, has a wide range of pharmacological activities, while its poorly aqueous solubility limits the development of solid oral dosage forms. In this study, PUE along with nicotinamide (NIC) were prepared into the coamorphous system by solvent-evaporation method and characterized by powder X-ray diffraction (PXRD), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (FT-IR). In addition, its dissolution behavior and solubilization mechanism were also investigated. PUE-NIC coamorphous was a single homogeneous binary system, with a single glass transition temperature at 35.1 ℃. In comparison to crystalline PUE, during the dissolution process, coamorphous PUE-NIC not only exhibited the "liquid-liquid phase separation" (LLPS) phenomenon, but the formation of A_p type complexation (1∶1 and 1∶2) between PUE and NIC molecules was also verified, which significantly improved the solubility of PUE and prolonged the supersaturation time, and would benefit its absorption.

Objective To predict and identify liner B-cell epitopes in the hemagglutinin ( HA) of human-infected avian-origin H7N9 influenza virus and analyze the specificity of H7 subtype.Methods Three serum samples collected at different times from the same patient who was confirmed to be infected with H7N9 influenza virus were provided by Shaoxing People’s Hospital, and one serum sample from healthy person was collected as the control.The extracellular region of HA protein was predicted by TMHMM Sever v.2.0.The potential B-cell epitopes were predicted by DNAStar Lasergene’ s Protean, BcePred and ABCpred tools, and the immunogenicity of the predicted B cell antigen epitopes was assessed by indirect enzyme-linked immunosordent assay ( ELISA ) .H7 subtype specificity was analyzed by comparing HA protein amino acid sequence with H7N9 and H1-H16 subtype influenza virus from Genbank using Clustal X 2.1 software, and Cn3D 4.3.1 software was used to detect the distribution and 3D structure of predicted epitopes on the HA protein of H7N9.Results The potential B-cell epitopes may be located in 172-183, 363-380, 452-472 and 491-506 of extracellular N-terminus of HA protein.ELISA showed that four predicted eptiopes specifically reacted with positive serums from patient.Multi-sequence alignment demonstrated that peptide 172-183 and 363-380 had higher H7 subtype specificity compared with amino acid sequences of other subtypes.Moreover, the predicted linear B-cell epitopes all located on the surface of HA protein according to the 3D structure analysis.Conclusion Four potential B-cell epitopes were identified, in which peptide 172-183 and 363-380 have higher H7 subtype specificity, and may be used in the design of epitope-based vaccines and diagnostics tests.

OBJECTIVETo observe the synergistic effect of beta-elemene Injection (betaI) combined Paclitaxel Injection (PI) on breast cancer MB-468 cells and to study possible mechanisms.

METHODSBreast cancer MB-468 cells were treated with betaI (2.5, 5.0, 10.0, 20.0, 40.0, 80.0, 160.0, 320.0, and 640.0 microg/mL), PI (0.00100, 0.00200, 0.00400, 0.00800, 0.01600, 0.03125, 0.06250, 0.12500, and 0.25000 microg/mL), and betaI combined PI for 24 h and 48 h respectively. Cell proliferation was determined using SRB assay. Cell apoptosis and cell cycle phase distribution were detected using flow cytometry. The post-intervention expressions of cell cycle proteins [cyclin-dependent kinase (CDK1), cyclin-B1, P21(cip1), and P27(kip1)] were detected by Western blot.

RESULTSBeta-elemene or paclitaxel inhibited the growth of MB-468 cell line. The IC50 and IC20 values treated with beta-elemene for 24 h were 34.20 and 52.59 microg/mL and for 48 h were 10.15 and 17.81 microg/mL respectively, while the IC50 values treated with paclitaxel for 24 h and 48 h were 2.449 and 1.698 microg/mL respectively. Beta-elemene (20 and 40 microg/mL respectively) and Paclitaxel (0.016 and 0.008 microg/mL respectively) synergistically inhibited cell proliferation of MB-468 cells, with Q value > 1.15. Beta-elemene alone (52.59 microg/mL) apparently decreased the expression of cyclin-B1 protein. The expression of cyclin-B1 protein in the combined group was also lower than that in the PI group (1.698 microg/mL). The expression of P27(kip1) was up-regulated when compared with that in the betaI group or the PI group.

CONCLUSIONBeta-elemene had synergistic effect with Paclitaxel, and its possible mechanism might be correlated with down-regulating the cell cycle protein cyclin-B1 expression and up-regulating the P27(kip1) expression.

OBJECTIVETo evaluate the clinical efficacy of treating myelodysplastic syndrome (MDS) by hematopoietic stem cell transplantation (HSCT) combined with Chinese medical syndrome typing.

METHODSFrom July 2009 to July 2013, 6 MDS patients were treated with allo-HSCT combined with Chinese medical syndrome typing from HLA-identical sibling donors at Department of Hematology, Zhejiang Provincial Hospital of Chinese Medicine. Patients were classified as refractory anemia (RA, 2 cases), refractory anemia with ringed sideroblast (RARS, 1 case), refractory cytopenia with multilineage dysplasia (RCMD, 2 cases), and RA with excess blasts-I (RAEB-I , 1 case). Modified BuCy conditioning regimen was used in all 6 cases. Two patients received bone marrow transplantation (BMT), 1 patient received peripheral blood stem cell transplantation (PBSCT), and 3 patients received BMT + PBSCT. In order to prevent the occurrence of graft-versus-host disease (GVHD), all patients were treated with cyclosporine + methotrexate + mycophenolate mofetil. Different Chinese medical treatment methods (by syndrome typing) were given to patients according to different criticality of international prognostic scoring system (IPSS, 5 at moderate risk and 1 at high risk).

RESULTSAll 6 patients successfully reconstructed their hematopoietic system. The time from transplantation to ANC ≥ 0.5 x 10(9)/L and platelet (PLT) ≥ 20 x10(9)/L were 13 (9-15) days and 11 (9-22) days respectively. Main complications were GVHD. Acute GVHD (aGVHD) occurred in 4 cases, 3 cases of grade I and 1 case of grade II, and local chronic GVHD (cGVHD) occurred in 1 patient. All cases survived with median follow-up of 18 (11-58) months. The overall survival (OS) and disease-free survival (DFS) rate were 100%.

CONCLUSIONSHSCT combined with Chinese medical syndrome typing could improve clinical symptoms, reduce transplant as- sociated complications. So it was an effective treatment choice for MDS.

Abstract: Objective　In order to provide reference for emergency treatment of a sudden food poisoning incident, pathogen detection and drug resistance analysis were carried out. Methods　Diarrheal stool and surplus food samples were detected by GB 4789 and the isolates were identified by VITEK2 and matrix assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS), at the same time, the bacterial drug sensitivity test was carried out by using the method of microbroth dilution, and the isolates from different sources were molecularly classified by pulsed field gel electrophoresis (PFGE), and the correlation between the strains was analyzed by BioNumerics software. Results　Totaly 13 leftovers and 3 diarrhea patients were isolated and identified, The total number of colonies and coliforms in 7 leftovers samples all exceeded the standard, and Citrobacter freundii was detected in 5 leftovers and 2 stools. The results of drug sensitivity test showed that seven strains of Citrobacter freundii were sensitive to ciprofloxacin, tetracycline, chloramphenicol, gentamicin, amikacin, cefotaxime and meropenem, but completely resistant to ampicillin, and there was no multiple drug resistance. The results of pulsed field gel electrophoresis (PFGE) showed that 7 strains of Citrobacter freundii had the same PFGE bands and 100% homology, showing the same clone. Conclusions　This food poisoning incident was caused by Citrobacter freundii. The pathogen of food poisoning can be quickly and accurately determined by MALDI-TOF MS, which is beneficial to the early diagnosis and treatment of infectious diseases. It is suggested to strengthen the corresponding management, improve food safety awareness and prevent similar incidents.
