Objective　To investigate the early changes and clinical significance of plasma endothelin(ET) and nitric oxide(NO) in patients with acute brain injury.　Methods　The plasma ET and NO concentration at 1 day after injury were checked with radioimmunoassay and Green method in 48 cases of acute brain injury, in 42 cases of non-brain injury and in 38 healthy volunteers. 　Results　 The early plasma concentrations of ET and NO were (109.73±12.61) ng/Lf and (92.82±18.21) μmol/L, respectively, in 48 cases of acute cerebral injury, which were higher than those in the non-brain injury group［(67.90±11.33) ng/L and (52.66±12.82) μmol/L, respectively, P<0.01］ and in the normal control group ［(50.65±17.12)ng/L and (36.12±12.16) μmol/L, respectively, P<0.001］. The amounts of ET and NO in the patients with severe brain injury were (116.18±18.12) ng/L and (108.19±13.28) μmol/L, respectively, which were significantly higher than that of the moderate brain injury group［(92.33±16.32) ng/L and (76.38±12.71) μmol/L, respectively, P<0.01］.The early levels of ET and NO were negatively related to the GCS scores of the patients with acute brain injury. The amounts of ET and NO were (126.23±15.23)ng/l and (118.18±10.12) μmol/L, respectively, in the patients with subdural hematomas, which were significantly higher than those in the patients with epidural hematomas ［(81.13±12.37) ng/L and(68.02±13.18) μmol/L, respectively, P<0.01］. The stable plasma concentrations of ET and NO at 14 days after injury in the patients with acute brain injury and with non-brain injury were similar to that in the normal controls. 　Conclusions　 ET and NO are related to the pathophysiological process in the early period of acute brain injury, and the values of ET and NO correlate positively with the clinical manifestations. The changes of plasma ET and NO can be regarded as important indexes to diagnose the severity of acute brain injury.

Objective To investigation the relationship between health management and prognosis of chronic prostatitis. Methods Three hundied and forty-six cases of chronic prostatitis were divided into two groups. The control group treatment was local washing and medicine for three months. The experiment group treatment was local washing, medicine, and health management for three months. NIH-CPSI was used for the results. Results There was no significant different between the experimental group(165 cases)and the control group(154 cases)before treatment in NIH-CPSI. The effective rate of the the experimental group was 88.5%, and that of the control group was 64.9% after treatment. It is effective for cure and the prognosis of the experiment was better than the control (P<0.05). Conclusion It is suggested that it is more effective for the prognosis of chronic prostatitis after the intervention of health management.

To evaluate the influence of different brands of syringes on performance parameters and application quality of syringe pump, we carried out matching experiment of infusion/syringe pump analyzer Rigel Multi-Flo, made by ALK Co. in Sweden, for 3 different types of syringes to measure the flow rate, occlusion alarm pressure, occlusion time and bolus volume of 26 syringe pumps. Data of quality control were analyzed with statistical method. The results demonstrated that there were significant differences in the flow rate, occlusion alarm pressure, occlusion time and bolus volume (P<0. 01) between those of common syringes and original syringes. This study points out that the health care providers should select compatible syringes for syringe pumps, which provides evidence and guidance to assure the reasonable and safe application of syringe pumps in clinical practice.

Objective To explore the etiopathology of slow transit constipation(STC). Methods The model of rat with cathartic colon was established and the changes of colonic electromyography and reaction to acetylcholine(Ach) were examined. Result The frequency, amplitude of slow wave and colon reaction to Ach of rats with cathartic colon decreased markedly. Conclusion Long term abuse of stimulant laxatives could damage enteric nervous system(ENS) and accelerate the pathological changes of STC.

OBJECTIVE To study the disposition,hospital divisions and risk factors that induce nosocomial infections,and approach utility measure for prevention.METHODS To investigate and analyze the nosocomial infections in the patients who hospitalized from 2004 to 2006,through the way combined with retrospective investigation and the cases report by doctors.RESULTS In our hospital,the nosocomial lower respiratory tract infection was the highest(33.7%).The second was the upper respiratory tract infection(23.0%),and the gastrointestinal tract infection(18.7%).The incidence of nosocomial infection in medical and paediatrics department was higher than other departments,the main infection site in internal medicine department was lower respiratory tract(49.1%),but in pediatrics it was skin soft tissue infection(41.6%).There was significance difference of risk factors in nosocomial infection.CONCLUSIONS To grasp the causes of nosocomial infection,emphasize the monitoring for the high risk factors in departments,strengthen the prevention for nosocomal infection among the staff,standardize the various kinds of nursing operation and reasonably apply antibiotics,all are the effective measures for the prevention of nosocomial infection.

98%. Conclusion This method was suitable for the determination of trace arsenic in cosmetics.

To design an inpatient charging management system to optimize the patient accounting flow. The problems in all links were analyzed, and auditing mode and flow were modified. Under the existing HIS, the sys-tem was developed with added datasheets, determined elements, desired rules, .Net framework and C# language. The system made the prescription linked with the charging so that the doubtful items could be marked automatically. The system facilitates the fee auditing, shortens the waiting time of the patient, enhances the communication between the departments and promotes the quality of medical records.

Objective To investigate the clinicopathological features of central nervous system hemangioblastoma in von Hippel-Lindau syndrome.Methods The data of 10 patients with central nervous system hemangioblastoma in our hospital since 2013 were analyzed retro-spectively,and the clinicopathological features of central nervous system hemangioblastoma in von Hippel-Lindau syndrome were summarized. Results The macroexamination result showed that most tumor lesions were found in the cerebellum and medulla oblongata,with cystic chan-ges,size from 1 cm to 5 cm,the average size was (3.1 ±0.2)cm,clear boundary,intracapsular yellow cyst fluid.The microscopy result showed tumor foci with a rich blood supply,endothelial cell proliferation and hypertrophy in vascular,which arranged in nests or lobulated mesenchymal cells,the cytoplasm of stromal cells was abundant and lightly stained,a rich lipid was seen,with vesicular or foam.Conclusion The von Hippel-Lindau syndrome is usually cystic lesion,the microscopic examination shows tumor foci with rich blood supply,endothelial cell proliferation,hypertrophy and other changes in vascular.
