Medical safety management and non-medical safety management are two major systems of hospital safety management.With the deepening of the medical and health system reform and the change of the mode of medical treatment,the connotation and extension of non medical safety management have changed,and the non-medical safety management field is faced with more risk factors and security risks.Combined with the.status quo of non medical safety management in hospital,the problems existing in non-medical safety management are analyzed and some suggestions for improvement are put forward.

Objective To investigate the physicochemical property of Pae-6’O-benzene sulfonate ( CP-25 ) . Meth-ods The CP-25 physicochemical property was evaluated by appearance, Lieberman-Burchard reaction, thin-layer chromatogram, Ultraviolet Spectrophotometry ( UV) , solubility and stability. The content of CP-25 was assayed by high performance liquid chromatography. Results The CP-25 had color response featured by terpenoid, and its maximum UV absorption wavelength was 220 nm. CP-25 was slightly soluble in water and petroleum ether. The main influence factor of CP-25 stability was humidity. Conclusion The present study provides experimental basis for quality standard and formulation design of CP-25 .

Objective To study the clinical characteristics and treatment of adult patients with tsutsugamushi disease in Nantong area,and to reduce the misdiagnosis and missed diagnosis.Methods Clinical data of 24 adult patients with tsutsugamushi disease who were admitted between 2010 and 2012 at Department of Emergency Medicine in Affiliated Hospital of Nantong University were reviewed retrospectively.The patients were 13 males and 11 females who were aged from 25 to 70 years old.Minocycline capsule was orally administrated as the mainstay of the therapy.Results All of the 24 cases of tsutsugamushi disease were presented with fever,predominantly with high fever.The body temperature of higher than 39 ℃ was recorded in 23 cases,and temperature of 38.0 ℃ to 38.9 ℃ was recorded in one case.Three cases complained with sore throat and cough,and 1 case with palpitation and chest distress.One eschar or ulcer was seen in 21 cases,2 eschars or ulcers only in 1 case.Twenty-one cases were presented with lymphadenopathy,11 cases with rash,3 cases with enlargement of the liver,and 4 cases with splenomegaly.The distribution of eschar or ulcer included inaxillary fossa,groin,external genitalia and crissum,waist,popliteal fossa,the lower edge of the female breast and skin folds of chest wall,the inside of the wrist,ankle,neck,retroauricular region,chest-back and the buttocks.The white blood cell count of (2.5-3.9) × 109/L in blood routine test was seen in 4 cases,(10.1-18.6) × 109/L in 3 cases.The blood platelet count was decreased in 1 case.Urinary protein was positive in 4 cases by urine routine examination.Blood biochemical examination revealed that elevated serum alanine aminotransferase was seen in 2 cases,elevated serum creatinine was in 1 case,mildly elevated cardiac troporin I was in 1 case,increased C-reactive protein was found in 19 cases.On Weil-Felix test,17 cases showed OXk titers of 1∶160-1∶320.Four cases showed an increase in overall lung markings,localized pulmonary infiltration shadow and even small pleural effusion on chest radiography.Electrocardiogram showed premature ventricular beats and slight ST segment changes in 2 patients.Oral minocycline showed obvious effect.Conclusions The clinical manifestations of tsutsugamushi disease can be variable.Multi organ dysfunction could be presented besides fever.The skin eschar and ulcer are the most pathognomonic for this disease and thus should be thoroughly examined for its presence to avoid misdiagnosis.

AIM: To investigate the clinical efficacy and safety of intravitreal injection of triamcinolone combined macular grid photocoagulation treatment for macular edema.
METHODS: Totally 150 cases (150 eyes) with macular edema in our hospital from July 2009 to November 2013 were selected, which were randomly divided into study group (75 cases, 75 eyes) and control group (75 cases, 75 eyes) . The cases in control group were treated with macular grid photocoagulation treatment, those in the study group used triamcinolone acetonide combined macular grid photocoagulation treatment. Best corrected visual acuity ( BCVA ) , parallel optical coherence tomography ( OCT) and fundus fluorescein angiography (FFA) were detected before treatment, after treatment 7d, 1, 3, and 9mo.
RESULTS:After the treatment, patients' vision were significantly improved in two groups (P<0. 05). In the study group 7d, 1, 3, and 9mo after operation, the visual acuity was better than the control group and preoperative (P<0. 05); fovea macular neurosensory layer thickness decreased significantly (P<0. 05). In the control group, the point omentum macular neurosensory retinal thickness was not statistically significant at 7d, 1, 3, and 9mo after operation compared with before treatment (P>0. 05). Fovea macular neurosensory retinal thickness in the study group was significantly lower than that in control group (P<0. 05). Intraocular pressure of 7 cases in the study group increased slightly, and were normal after treatment.
CONCLUSION: Triamcinolone acetonide combined macular grid photocoagulation treatment is accurate, can effectively improve the visual acuity, reduce macular edema, it is safe and reliable, and suitable for clinical application.

As a member of tyrosine kinases(TK) family,Epidermal growth factor receptor(EGFR) has an activity of intrinsic protein tyrosine kinase,which plays an essential role in the regulation of signal transduction in the cells.Due to the abnormal expression of EGFR-TK,the certain type cancers may developed and progressed.Based on that,the inhibitors of EGFR-TK could be effective medicines for the treatment of cancer.The EGFR-TK domain was amplified by RT-PCR with RNA of HUVCEs cells as the template and expressed in E.coliBL21(DE3) using plasmid pET30a as vector.The recombinant protein was purified with the affinity chromatography(Ni-NTA),which was identified to have kinase activity catalyzing the substrate phosphorylated with ATP in the enzymatic reaction.Using the recombinant EGFR-TK as target,the screening model for enzymatic inhibitors was constructed.

Hair follicle stem cells located bulge region of hair follicle,had characteristics of all adult stem cells,including slow-cycling,undifferentiated.They also had the abilities of self-renew and proliferation in vitro.CD34,K15,K19 and Nestin might be the makers of the hair follicle stem cells.They could be induced to differentiate to neurons,glial cells,keratinocytes,smooth muscle cells,melanocytes In vitro and neurons,melanocytes in vivo.There were many signals in regulating the hair follicle stem cells involved Wnt signal,BM Psignal and NFATc1 etc.

To measure the relative affinity and type Specificity of neutralizing monoclonal antibodies against the hexon antigen of adenovirus type 7,a simple ELISA double antibody binding system has been developed.By this method,ralative affinity of nine MAbs was estimated from the antibody concentrations at approximately 50% of plateau binding and were ranked.The theoretical basis for this method was discussed. Hybridomas secreting antibodies of desired affinity can be selected at an early stage after fussion by measuring relative affinity of hybridomas supernatants.The type specificity was judged by the difference between end-point concentration against adeno- virus type 7 and type 3.And the relation between affinity and specificity of MAbs was discussed.
