Based on the analysis of current status of medical service process including the service in out-patient, hospitalization, test, examination, nursing, and so on, the paper describes the bottlenecks and major existing problems of current medical service process. And it further discusses how to make full use of the advanced health information technology, make scientific and reasonable arrangements for all links of medical service, reconstruct medical service process facing the patients, and optimize and reengineer the medical service process.

The administration status of enteric coated aspirin in 348 diabetic patients aged over 40 from Xujiahui Subdistrict of Shanghai was surveyed. One hundred and two out 348 patients ( 29. 3% ) used aspirin regularly, among them only 36 cases used the correct dosage (75 - 162 mg/d), accounting for 10. 3% (36/348) of all patients surveyed. The results indicate that aspirin was not used properly in diabetic patients to prevent the heart and cerebrovascular diseases,and it is necessary for medical providers to promote health education for diabetic patients.

A major task in clinical trials and researches is subject recruitment, however there probably exist ethical issues in the process of recruitment, such as the selection of subjects, recruitment methods, document de-scription,reward and compensation. This paper is to discuss the relevant ethical elements through cases analysis. It put forward that only obeying ethical codes, implementing informed consent, and playing the function of ethics com-mittee, the rights and interests of subjects can be protected.

lntraocular lens ( lOL) often has different degrees of tilt, decentration and rotation in the eye. The deflection of lOL is an important factor to impact on the visual quality of the patients with cataract surgeries. Vision was commonly used to evaluate visual quality before. ln recent years, some new methods are also introduced to evaluate visual quality, such as optical aberration, modulation transfer function ( MTF ) and subjective visual perception. They show that the lOL deflection will cause decreases in eyesight and MTF, cause increase in aberration, lead to ametropia and so on. Therefore, a better evaluation of the effects of lOL deflection on visual quality, has significance for lOL selection, positioning and cataract individualized treatment.

Electrical stimulation is a common technology to treat neurogenic bladder dysfunction secondary to supersacral spinal cord injury. This paper reviews the historical development of this treatment and current status.

Objective To explore the clinical effects of ropivacaine in combined spinal-epidural anesthesia (CSEA) in the aged patients undergoing lower limb surgery. Methods Sixty patients, aged 65 and over, in American Society of Anesthesiologists (ASA) physical status Ⅱ-Ⅲ, and undergoing internal fixation surgery for lower limb bone fracture, were randomly assigned to three groups in equal number: group R1 (hypobaric ropivacaine for lumbar anesthesia), group R2 (hyperbaric ropivacaine for lumbar anesthesia) and group B (bupivacaine for lumbar anesthesia). The observed variables included the changes in blood pressure and heart rate, sensory block level and motor block status. The drug consumption in epidural anesthesia and the peri-operative side effects were noted. Results The anesthetic efficacy was satisfactory in all patients. The onset time of anesthesia in group B (54.05?3.80 s) was obviously shorter than that in group R1 and group R2 (61.10?4.96 and 60.95?3.94 s, respectively, P

Objective To investigate the effect of posttraumatic stress disorder(PTSD) on the psychological healthy state among high school students in the earthquake regions.Method The samples were consisted of 666 high school students who had experienced the Wenchuan Earthquake.The Impact of Event Scale-Revised (IES-R) and Self Description Questionnaire (SDQ) were used to rate symptoms of PTSD and psychological states of high school students.Data were analyzed using correlation analysis and structural equation model analysis for male or female separately.Results (1) Because their scores of IES-R were higher than 35,22.67％ participants were considered as PTSD patients,girls accounted for 83 or 25.31％ of the total female;and boys accounted for 68 or 21.72％ of the total male.(2) Among female,avoid and awake systems of PTSD were correlated significantly with their psychological state significantly (r=0.101-0.181,P＜0.05).The result of structural equation model analysis was similar to correlation analysis,corresponding coefficients of path ranged 0.11 to 0.18 (P＜0.05).(3) Among male,intrude and awake systems were correlated with their psychological state significantly (r=0.111-0.313,P＜0.05).Corresponding coefficients of path ranged from 0.11 to 0.31 (P＜ 0.05).Conclusion Systems of PTSD effect clearly on the psychological state of high school students,and there are the gender difference among these relationships.The symptoms of PTSD influence interpersonal relationships,emotion,conduct,appearance and self-evaluation,but school work and stamina are not influenced in this study.

Objective To investigate the CT presenting rate and features of gastric bare area (GBA, including the area posterior to GBA and the adipose tissue in the gastrophrenic ligament) without pathologic changes.Methods Thirty cases with superior peritoneal ascites, but without pathological involvement of GBA were included into the study to show the normal condition of GBA, including the presenting rate and CT features. We selected some cases with GBA invasion by inflammation or neoplasm to observe their CT features. Results All cases with superior peritoneal ascites showed the GBA against the contrast of ascites with the presenting rate of 100%. The GBA appeared at the level of gastric esophageal conjunction and completely disappeared at the level of hepato duodenal ligament and Winslow’s foramen. The maximum scope of GBA presented at the level of the sagital part of the left portal vein with mean right to left distance of (4.39? 0.08 )cm (3.8～5.7 cm) (distance between the left and right layer of the gastrophrenic ligament). In acute pancreatitis, the width of GBA increased, in which local hypo density area could be seen. In gastric leiomyosarcoma invading GBA, the mass could not separate from the crus of the diaphragm. In lymphoma and metastasis invading GBA, the thickness of GBA increased and the density was heterogeneous, in which lymph nodes presenting as small nodes or fused mass. Conclusion The results of this study show that it is helpful to use contrast enhanced spiral CT scanning to observe the change of GBA and to diagnose retroperitoneal abnormalities that involving GBA comprehensively and accurately.

Objective To investigate the physical and mechanical properties of home-made bone cement mixed with different antibiotics.Methods The specimens of bone cement each of 40g were divid-ed in to6groups depending on mixed antibiotics,groupⅠmixed with1g gentamicin,groupⅡwith2g gen tam icin,groupⅢwith1g cephradine,groupⅣwith1.5g cefuroxine,groupⅤwith1g ceftriaxone and groupⅥwith out any antibiotics served as control.The dough time,compressing depth,compressive strength,bending strength and bending elastic modulus were measured respectively,elution examination of antibiotics from bone ce ment was performed by chromatography.Results The dough time and compress-ing depth of the groups were better than that of ISO5833standard,and there was no significant difference a-mong the groups.The com pressive strength and bending strength of the groupⅡwere lower than that ISO5833standard,but there was no significant difference among the groups by analysis of variance.The bending elastic modulus of the groupⅡwas lower than the control group and other groups(P
