Objectives: This study aimed to evaluate the effect of optimistic bias of female AIDS/HIV carriers before and after the health education in penitentiary.Methods: Two questionnaires including AIDS Events Questionnaires and AIDS Knowledge Scale are conducted among 57 female AIDS/HIV carriers after receiving health education in penitentiary.Results: Female AIDS/HIV carriers from the penitentiary had both type I and typeⅡoptimistic bias of AIDS/HIV;Female AIDS/HIV carriers from the penitentiary acquired significantly more knowledge after receiving health education,the health education of AIDS/HIV had significantly reduced the optimistic bias to AIDS/HIV.Conclusion: Health education of AIDS/HIV had notably changed the cognitive ability and reduced optimistic bias to AIDS/HIV of female AIDS/HIV carriers from the penitentiary,therefore effectively corrected their irrational ideas of AIDS/HIV.

OBJECTIVE To attend to the importance and issues of using the enzyme cleaner for the reprocessing of medical instrument. METHODS The principle, usage, precautions, and the selection of enzyme cleaner were analyzed. RESULTS The cleaning of the medical instrument must use the liquid enzyme detergent that has the following characters: clear solution, no or low foam, free rinsing, flexibilities to the water temperature, and no limitation to the water quality. CONCLUSIONS For successful cleaning of the medical instrument the use of the high-quality enzyme cleaner is required. A complete cleaning of the medical instrument is the first step to assure the quality of disinfection, sterilization, and the infection control.

Objective To evaluate pericardial devascularization with splenectomy (PCDV) for the treatment of cirrhotic portal hypertension. Methods From January 1994 to December 2004, 177 patients were treated by PCDS, among them posthepatitic cirrhosis was identified in 170 cases, and alcoholic cirrhosis in 7. One hundred and thirty two patients were operated on electively, 25 prophylactically, and 20 emergently. Results The bleeding control rate was 95% , the overall operative mortality rate was 4. 5%. The main causes of death were upper gastrointestinal bleeding, hepatic failure and intra-abdomimal hemorrhage. The mean follow-up time was 3. 6 years. The 5-year survival rate was 90%. The 5-year recurrent bleeding rate was 5. 1% , The rate of postoperative hepatic encephalopathy was 5. 1%. Conclusions This procedure has the advantage of high successful rate of bleeding control, low complication rate, and long term survival.

Objective To study the effects neuromuscular electrotherapy and kinesitherapy on brachial plexus palsy. Methods 20 patients with brachial plexus palsy accepted neuromuscular electrical stimulation on involved muscles, and were followed up for 18～58 months. Other 17 patients accepted neurolysis alone were as control. Results The function of shoulder and elbow in electric stimulation group was significantly superior to that of control (P<0.01). Conclusion Neuromuscular electrotherapy combined with kinestherapy is effective on the brachial plexus palsy.

Objective:To Search allele loss in glioma at chromesome 9p21-22 by microsatellite.Methods:Loss of heterozy gosi ty (LOH) and Microsatellite instability(MSI) was examined in 29 gliomas using PC R based methods.Results:No LOH and MSI on chromosome 9p21-22 was de tected in 29 gliomas at three loci.Conclusion:①There may be no othe r suppressor gene at 9p21-22 in glioma except p15 and p16.②MSI is infrequent i n sporadic gliomas.

This study is to investigate the effect of Vam3, a dimeric derivative of resveratrol, on SNP-induced apoptosis and its potential mechanism in rat articular chondrocytes. Isolated rat articular chondrocytes were treated with sodium nitroprusside (SNP), a NO donor, to induce apoptosis. Apoptosis percentage was evaluated by Annexin V-PI and nucleus fracture was examined by DAPI staining. Level of intracellular reactive oxygen species (ROS) was detected using 2, 7'-dichlorofluorescin diacetate (DCFH-DA) as a fluorescence probe by fluorescence microplate reader. The change in mitochondrial membrane potential was detected by TMRE staining. Expressions of SIRT1, acetylated p53 (ac-p53), cleaved caspase 9 and cleaved caspase 3 were determined by Western blotting. It showed that Vam3 up to 10 micromol x L(-1) could significantly reduce SNP-induced rat articular chondrocytes apoptosis (P < 0.01) and nucleus fracture, inhibit the increase of intracellular ROS level (P < 0.01) and reverse the decrease in mitochondrial membrane potential (P < 0.01). Simultaneously, Vam3 could upregulate the expression of SIRT1, deacetylate p53, and inhibit the cleavage of caspase 9 and caspase 3 (P < 0.01) of rat articular chondrocytes exposed to SNP. This study indicates Vam3 could protect rat articular chondrocytes against SNP-induced apoptosis, perhaps through the upregulation of SIRT1 and deacetylation of p53.

Visceral myopathy is a rare disorder characterized by atrophy,losing and fibrosis of visceral smooth muscle.Digestive tract is often invaded by the lesions,and the symptoms are various according to different lesions and degrees.Small intestinal involvement is characterized by abdominal distension,diarrhea and vomiting.Colon involvement is characterized by chronic intestinal pseudoobstruction.Malnutrition and hypoproteinemia may be secondary to this disease.The diagnosis of visceral myopathy is difficult,paralytic ileus,chronic constipation and systemic sclerosis must be considered in the differential diagnosis.The progression of the disease is slow,and the longterm prognosis is poor.In this article,the diagnosis and treatment of visceral myopathy causing acute intestinal pseudoobstruction were introduced based on the clinical data of 1 patient.

Objective To explore whether fluid-attenuated inversion recovery can be used to estimate the onset time of acute ischemic stroke (ALS) based on the analysis of signal strength through the fluid-attenuated inversion-recov?ery (FLAIR)and volume of interest (ROI) in ALS patients with known time of onset. Method Forty-seven AIS patients who met the inclusion criteria were recruited from Baotou Central Hospital, Department of Neurology from January 2011 to December 2012. The patients had stroke onset within 12 hours and completed MRI scan including diffusion-weighted imaging DWI, apparent diffusion and coefficient ADC FLAIR. Based on MRI findings, patients were divided into, three groups:0~180 min, 180~360 min and 360~720 min groups. Signal strength values of the DWI、FLAIR and ADC in ipsi?lateral and contralateral sides were measured. Result There was a significant difference in the FLAIR signal strength among these three groups.The FLAIR signal strength was significantly lower in 0~180 min and 180~360 min groups than in 360-720 min. FLAIR positive rate was 16.7%, 62.5%, and 70.6% in 0~180 min, 180~360 min and 360~729 min groups, respectively. Conclusion FLAIR positive rate gradually increases as the onset prolongs. Thus, lower FLAIR posi?tive rate indicates shorter onset time of AIS, which can be used to assist acute intravenous thrombolytic therapy.

Bacterial disinfectant resistance is the phenomenon that minimal inhibitory concentration or minimal bactericidal concentration of a certain disinfectant increases after a certain bacterium contacts with it many times. It exists widespread. Many species of bacteria are may resistant to a certain disinfectant, and a species of bacterium is may resistant to many disinfectant Disinfectant selectivity pressure is the extrinsic agent of bacterial disinfectant resistance. Resistance mechanisms include bacterial biochemistry structure, genetics pathway and enzymology pathway. There is relationship in disinfectant resistance and drug resistance. We should strengthen study and monitoring, enact unified standard and application specification to reduce bacterial disinfectant resistance.
