Objective To learn the relationship between working pressure and mental health for nurse of transfusion room in pediatric department.Methods 120 nurses of transfusion room whose working years above half a year were investigated by questionnaire from January 2010 to December 2011.Results The maximal score of working pressure was working environment and resource (3.27±0.47),while the minimum was interpersonal relationship (1.80±0.68).The score of SCL-90 of the research group was higher than domestic model.More working pressures of transfusion room in pediatric department were positive correlated with SCL-90.Conclnsions In order to keep nurse sound in body and mind,the working pressure should be desolved in many ways.

Three widely used methods of sediment toxicity evaluation were introduced in the present paper, including organism toxicity tests, toxicity identification evaluation(TIE) and sediment quality guidelines(SQGs). Compared with the chemical analysis, toxicity tests have an advantage of taking the bioavailability of POPs into account, however, it fails to identify the causative toxicants. TIE, integrating with physicochemical analysis, implicates the specific pollutants in a tiered approach, and by which effective remediation can be designed accordingly. The sediment toxicity can be identified more quickly and appropriately by SQGs than by the former two methods. The differences among the different SQGs constituted by different standards may affect their values for toxicity evaluation. Extensive and reliable SQGs had been acquired to improve their utility. Finally, the combination of chemical analysis, toxicity tests and in situ bioassays will be the trend of sediment toxicity evaluation in the future.

Objective To investigate the clinical outcome of post-traumatic tibial osteomyelitis treated by induced membrane technique combined with the antibiotic cement-coated locking plate.Methods A restrospective case series analysis was made on 71 cases of post-traumatic tibial osteomyelitis treated by induced membrane technique from September 2014 to September 2014.There were 55 males and 16 females, aged 18-60 years(mean, 37.4 years).Mean length of bone defect following debridement was 4.5 cm(range, 4-11 cm).Antibiotic cement-coated locking plates were used to provide the stability of the bone defects after one-stage debridement.Bone grafting and exchanging the plates with ntramedullary nails were done during the second-stage surgery.Parameters were monitored dynamically after operation to evaluate infection recurrence and bone healing, including C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), clinical features(sinus formation, redness and swelling, warmth and pain) and X-ray films of the involved limbs.Results All patients were followed up for 13-25 months (mean, 19.5 months).There was no sign of recurring infection and CRP and ESR were normal in all cases after the first stage surgery.However, four cases (6%) had recurrent infection with sinus exudates and their CRP and ESR were abnormal after the second stage surgery, and further treatments were carried out on these patients.Follow-up showed bony union in all patients within mean 5.5 months (range, 4-6 months).Conclusion Induced membrane technique with antibiotic cement-coated locking plates for treatment of post-traumatic tibial osteomyelitis can shorten bone healing time and decrease infection recurrent rate without obvious impact on osteogenic activity.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.

OBJECTIVE:To investigate the effect of clinical pharmacist intervention on prophylactic application of antibiotics in cardiothoracic surgery. METHODS:Medical records of patients underwent cardiothoracic surgery were collected from our hospi-tal during Mar. to Apr. in 2014 (before intervention) and during Jun. to Jul. in 2014 (after intervention). Those were divided into pre-intervention group(n=115)and post-intervention group(n=119). The prophylactic application effect of antibiotics was com-pared before and after intervention. RESULTS:After intervention,the rates of prophylactic application were decreased significantly from 96.5% to 72.3%;the rationality rate of antibiotics selection was improved significantly from 27.9% to 94.2%;The course of prophylactic medication decreased significantly from(5.4±2.8)days to(2.3±1.8)days;the difference had statistical significance before and after intervention(P<0.01). The postoperative infection rate was decreased from 13.0% to 5.9%,the difference had no statistical significance(P=0.074). The average hospitalization time,average drug costs,and average hospitalization expenses were decreased significantly,the difference had statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Clinical pharmacist inter-vention to prophylactic application of antibiotics in cardiothoracic surgery can control the infection effective and guarantee reason-able and safe use of drugs during perioperative period.

OBJECTIVE:To establish a method for the dissolution determination of Dronedarone hydrochloride tablet,and eval-uate the quality consistency of its generic and original preparations. METHODS:UV spectrometry was performed on the column of 288 nm,dissolution media of Phosphate buffer solution (pH4.5),0.1 mol/L Hydrochloric acid solution [adding into 0.5% sodium dodecyl sulfate(SDS)],Phosphate buffer solution [pH6.8,adding into 0.5%SDS] and water,volume of dissolution medium was 1 000 ml,rotation speed was 75 r/min,the dissolution of generic and original preparations of Dronedarone hydrochloride tablet was detected,and the similarity of dissolution curve was evaluated by calculating the similarity factor (f2).

Objective: To investigate the effects of low molecular weight heparin(LMWH) on vascular endothelial growth factor(VEGF) expression of early diabetic nephropathy. Methods: Ninety-five male SD rats were randomly divided into three groups: normal control rats, STZ-induced diabetic rats and diabetic rats treated with LMWH. The renal tissues were subjected to immunohistochemical staining after 1,2,4,6,and 8 weeks’ treatment respectively to quantify the VEGF expression. Results: Immunohistochemical staining demonstrated an increasing in VEGF positive cells in diabetic rats. It was found that there were significant differences in VEGF staining intensity between diabetic rats and normal control rats and between LMWH treated rats and untreated diabetic rats after two weeks treatment. Conclusion: The inhibition of VEGF expression may be one of the mechanisms of LMWH’s renal protective effects on early diabetic nephropathy.
