Objective To understand the simon and psychological state of HBsAg carriers among the students in university in order to make effective intervention measures. Methods The 5 items of hepatitis B in serum were tested by enzyme linked immunesorbent assay (ELISA) for each new students of grade 2008, and the influencing factor of serum items of hepatitis B were investigated by questionnaire. Symptom checklist 90 was adopted to test the psychological state of the HBsAg carriers. Results The total HBsAg positive rate was 6.77%.The serum maker model of HBV showed seven kinds. The HBsAg positive carder rate had significant difference in different gender, HBV-infected history, blood transfusion history and HBV vaccination history. The HBsAg positive carriers demonstrated evident depression, anxiety, hostility and fear. Conclusions The college students must pay attention to HBV precaution during their stay in university. Health education on HBV and prevention program should be implemented to prevent infection.

Objective To probe into the related factors and nursing of nosocomial infection for infectious diseases ward. Methods 2198 cases of patients in infectious diseases ward of our hospital were selected from February 2008 to December 2009, prospective monitoring and retrospective analysis were simultaneously adopted. Results In cases of nosocomial infection, mainly respiratory tract was the infection site, where the upper respiratory tract infection rate was 30.52%, lower respiratory tract infection rate was 28.57%, higher than other parts, there were significant differences. At the same time, nosocomial infection due to indwelling catheter and the irrational use of antibiotics led to higher rates of infection, 19.23%and 17.69%, there were significant differences. In addition, we could see from the age of nosocomial infection, ≤ 3-year-old children and elderly patients ≥ 60 years old had higher infection rate, 9.43% and 9.71%, there were significant differences. Conclusions According to elements features of infectious disease outbreak in hospital ward, to take effective care and prevention measures to reduce the infectious diseases room of the hospital infection will be of great clinical significance.

Changes of glycosaminoglycans in cerebrum, brainstem and cerebellum were measured in rats with hepatic encephalopathy induced by thioacetamide. It was foundthat the contents of glycosaminoglycans in brainstem and cerebrum were lowered markedlythan that of the normal control, but no significant difference of glycosaminoglycans werefound in cerebellum. The results suggested that the metabolism of glycosaminoglycans incerebrum and brainstem was disturbed when hepatic encephalopathy occured, and thatthe pathogenic mechanism of hepatic encephalopathy was related to the alterations of gly-cosaminoglycans in brain as a result of hepatic insufficiency.

Changes of pulmonary vascular permeability and blood gas were measuredin rats of experimental fulminant hepatic failure induced by thioacetamide. The resultsshowed that the pulmonary vascular permeability to Evans Blue in rats of fulminant he-patic failure with hepatic enphalopathy was markedly increased than that of normalcontrols (P

To analyze clinical, neuro-electrophysiologocal, imaging and pathological characteristics of Hirayama disease (HD) and review its relevant literatures to improve its diagnosis. Clinical data of two HD cases admitted to Fujian Provincial Hospital, Fuzhou during 2005 to 2008 were analyzed with literatures review. HD occurred more in males, often onset at their adolescence with muscular weakness and atrophy in one or two upper limbs, but without sensory dysfunction or pyramidal signs. Neuro-electrophysiology showed neurogenic abnormality in the body areas dominated by the 4th cervical vertebra to the 1 st thoracic vertebral (C4-T1) spinal nerves in all the patients. Magnetic resonance imaging (MRI) showed slight atrophy of the lower cervical spinal cord at routine position and its compression and forward displacement to varied extent at flexion position, with posterior epidural capsular space widening, crescent or striped high signal, and voids of vessels in some patients. Enhancement magnetic resonance scanning showed crescent sign enhanced in some patients. Biopsies of the inflicted muscles appeared slight neurogenic abnormality in some cases, and normal in other cases. HD is rarely seen clinically, but it can usually be diagnosed according to its symptoms, neuro-electrophysiology and MRI.

Objective To observe the hematocyte change in patients peripheral blood with severe hepatitis and to investigate its causes and clinical significance.Methods Partial parameters of peripheral blood cell in 65 patients with severe hepatitis and 52 normal individuals were analysed using blood cell counter.Results WBC number in patients with severe hepatitis was significantly higher than that in normal individuals[(8.13±4.33)×109/L vs(6.02±1.07)×109/L,P＜0.01],and PLT,PCT,MPV,PDW,RBC and Hb in the patients with severe hepatitis Were also significantly lower than that in normal individuals(P＜0.01).Conclusions Severe hepatitis can cause the hematocyte changes.It is essential to examine the hematocyte parameters in diagnosis and therapy of severe hepatitis.

OBJECTIVE:To study the perioperative use of prophylactic antibiotics in a hospital.METHODS:210 surgery patients were sampled randomly from Apr.to Aug.2006 in a hospital and investigated in respect of the perioperative use of prophylactic antibiotics based on the Guiding Principle of the Clinical Application of Antibacterials.RESULTS:Of the 210 cases,the ratio of perioperative use of antibiotics were as high as 98.10%,the application ratio of antibiotics in depuratory operation was 96.97%,and were 100% in other kinds of surgeries.The application ratios of antibacterials 0.5～2 h before surgery,after operation and during operation stood at 25.73%,21.84% and 52.43%,respectively.The average duration of antibiotic use was 3.17 d,with a maximum of 13 d.The duration of antibiotic use in depuratory operation,depuratory-contaminant operation and contaminant operation were 1.40,3.60 and 8.19 d,respectively.Antibacterials used singly totaled 23 kinds,of which,cefuroxime,latamoxef,amoxicillin/potassium clavulanate,cefminox and norvancomycin hydrochloride topped the first 5 places.CONCLUSION:The results show that the rate of application rate of antibiotics in this hospital is on the high side,the preventive medication indications were unclear and the drug use was lack of special aim,the management on which remains to be standardized.

Objective To estimate deployment of field medical equipment, which is aim at the manifold differences between field medical equipment in wartime or emergencies and common hospital equipment. Methods Based on a good many factors, the system of comprehensive evaluation index on field medical equipment deployment were built up. The model of comprehensive evaluation index was established in applicant of a grey system theory. By discriminating model parameters, the order of comprehensive evaluation is involved in various medical equipment deployments. Results The examples of the evaluation show that is simple and convenient, lesser relevance in indicators and the evaluative results and actual position are conformity. Conclusion The evaluated results of field medical equipment deployment are important for the selection of field medical equipment, which can meet all deployable conditions in wartime or various emergencies. At the same time, the theoretic method has also settled the foundation in evaluation of other military equipment deployment.

[ ABSTRACT] AIM:To investigate the effect of maxadilan, which specifically activates pituitary adenylate cycla-se-activating polypeptide type I receptor (PAC1 receptor), on the proliferation, apoptosis and differentiation potential of human adipose-derived stem cells ( ASCs) .METHODS:ASCs from human adipose tissue were isolated by enzymatic di-gestion and cultured.ASCs were confirmed by the analysis of the markers for cell phenotypes by flow cytometry ( FCM) and adipogenic/osteogenic induction.The effect of maxadilan on ASCs viability was analyzed by CCK-8 assay and FCM.ASCs were irradiated by ultraviolet C ( UVC) at 254 nm and the absorbance of apoptotic ASCs induced by various doses of UVC was measured by CCK-8 assay.ASCs were exposed to 702 J/m2 UVC for 24 h to induce apoptosis.The effect of maxadilan on ASC apoptosis was analyzed by FCM and the determination of caspase 3 and caspase 9 levels.RESULTS:Adipose-de-rived stem cells were confirmed by the detection of the positive expression of cell phenotypes including CD29, CD44, CD59 and CD105 by FCM.The data of CCK-8 assay revealed that ASCs treated with maxadilan (80 nmol/L) had the strongest ability of proliferation.The data of FCM also demonstrated that the addition of 80 nmol/L maxadilan to ASCs in experimen-tal group markedly improved the proliferation capacity of the cells compared with control group (P<0.05).The apoptosis of ASCs exposed to 702 J/m2UVC was dramatically inhibited by the treatment with maxadilan (80 nmol/L).Such process involved the caspase signaling pathway including caspase 3 and caspase 9.There was statistical significance (P<0.05) between experiment group ( ASCs irradiated by UVC and supplemented with maxadilan) and control group ( ASCs only irra-diated by UVC) .Meanwhile, adipogenic and osteogenic differentiation potentials were both positive in experiment group and control group.CONCLUSION:Maxadilan promotes proliferation and inhibits apoptosis of the ASCs.The differentia-tion potential of ASCs toward adipogenic and osteogenic lineages wouldn’ t be altered by maxadilan.Maxadilan would bene-fit to growth and expansion of ASCs in vitro.
