OBJECTIVE:To investigate the use of antibiotics in the inpatients of our hospital.METHODS:The medical records of inpatients from Jan.2004 to Dec.2006 randomly selected in our hospital were analyzed statistically in respect to the irrational use of antibiotics.RESULTS:Of the total 1,120 inpatient medical records examined,843(75.3%) used antibiotics,56 involved irrational use of antibiotics,which manifested as improper in dosage,dosage regimen,drug combination or solvents selection etc.CONCLUSION:The irrational use of antibiotics is quite common,thus the role of clinical pharmacists should be strengthened to promote rational use of antibiotics in clinical practice.

OBJECTIVE:To prepare Xiaozhong zhitong cataplasma,establish a method for its quality control and to observe its clinical efficacy on orthopedic patients(30 cases).METHODS:Based on the precompounded prescription order of Xiaozhong zhitong powder with water soluble polymer substance as base material which were evenly mixed with the drug extractives before being applied on non-woven fabric to prepare Xiaozhong zhitong cataplasma.The clinical efficacy was compared between the trial group(Xiaozhong zhitong cataplasma) and the control group(Xiaozhong zhitong powder).RESULTS:The prepared Xiaozhong zhitong cataplasma had smooth surface and uniform thickness,with a satisfactory stability achieved within 3 months at a dosage of 0.715 6 g?100 cm-2.The total effective rate in the trial group(93.3%) was significantly higher than in the control group(76.7%)(P

Objective To compare the advantages and disadvantages of the two methods.Methods Thirty BALB/c mice were randomly divided into 3 groups:normal control group,OVA group and OVA/RSV group.With ovalbumin and hydroxide suspension sensitized,OVA nouse asthma model group and OVA/RSV group were established respectively by continuous atomization of ovalbumin and repeated nasal drops of RSV.The control group was established by sensitization and atomization excitation of sterile injection water.24 hours after the last stimulation,the lung function was measured.The cell sorting and counting in bronchoalveolar lavage fluid were performed.The pathological changes of lung tissue were observed by HE staining.Results Compared with the control group,the model groups have obvious symptoms of asthma,airway wall thickening,lumen stenosis and a large number of inflammatory cell infiltration.And pathological damage of lung tissue in OVA/RSV group was significantly increased,compared with OVA group.The enhanced expiratory pause (Penh)values of OVA/RSV group were significantly higher than those in group OVA (P ＜ 0.05),and the number of neutrophils,monocytes,lymphocytes and eosinophils in BALF were significantly higher than those in OVA group (P ＜ 0.05).Conclusion The establishment of asthma mouse model by OVA sensitization and RSV induction is a better way to simulate the human asthma pathogenesis.

Objectives:To investigate the effects of amylin on bone minernal density and structure parameters of bone tissue in glucocorticoid induced osteoporosis rats. Methods:Four groups of female Wistar rats (3 months old) were treated for 12 weeks as follows: ⅠNormal Control, ⅡDXM, Ⅲ DXM+AMY;Ⅳ DXM+Vitamin Da 3. By intramuscular injection of dexamethasone(XM)1mg/kg twice a week during the first 8 weeks, the animal model of Glucocorticoid induced osteopoprosis was established. After 12 weeks, BMD of the lumbar vertebrae and the femural bone were measured by DEXA. The bone morphology of the lumbar vertebrae was also determined. Results:①After the treatment with AMY, bone mineral density (BMD) was significantly increased at the lumbar spine and the femural bone. ( vs. DXM group, P

Microbes that produce Docosahexaenoic Acid were isolated from seawater. 160 strains capable of producing lipids were screened out using Sudan Black B dying method from 280 seawater samples. From 60 strains of microorganisms producing bigger lipid particles, 7 strains of them capable of producing lipids more than 8% were obtained with Soxhlet abstracting method in the first screening. In the secondary screening from 10 strains with high lipids yield, strain 7-3 capable of producing 15.9% lipids was obtained, in which the content of DHA(Docosahexaenoic Acid)is 45.2%. Strain 7-3 was identified as Brettanomyces based on its morphological properties, cultural characteristics, physiological and biochemical properties.

Objective To compare the clinical characteristics of community-acquired acute kidney injury (CA-AKI) and hospital-acquired acute kidney injury (HA-AKI) patients.Methods Hospital network system was employed to screen the clinical data of adult patients in the First Affiliated Hospital in Xinjiang Medical University in January to July 2013.A total of 19 528 patients were screened,and 544 AKI patients were identified based on KIDGO (Kidney Disease:Improving Global Outcomes) AKI guidelines.Three hundred and thirty patients were included in HA-AKI group and 214 patients in CA-AKI group.Clinical variables including mortality were analyzed retrospectively.Results The incidence of AKI in hospitalized patients was 2.8％ (544/19 528):1.7％ in CA-AKI group and 1.1％ in HA-AKI group.The mean age in CA-AKI group was significantly older than that in HA-AKI group [(62.9 ± 16.8) years vs (56.6± 15.9) years].Medical patients in CA-AKI group accounted for 62.4％,and surgical patients in HA-AKI group accounted for 64.1％.The co-morbid diseases were cardiac disease,hypertension,diabetes and chronic liver disease.Majority of AKI was caused by pre-renal etiologies.The length of hospitalization was significantly shorter in CA-AKI group compared to that in HA-AKI group [12(8,20) days vs 19 (12,27) days,P ＜ 0.01].Compared to that in HA-AKI group,all-cause mortality was significantly lower in CA-AKI group (11.5％ vs 20.1％,P=0.005).Results by multivariate logistic regression analysis demonstrated that the common independent risk factors of AKI in both groups were ICU hospitalization and shock.The independent risk factor of AKI in CA-AKI group was diabetes (OR=3.019).In contrary,the independent risk factors of AKI in HA-AKI group were elderly (≥65 years) (OR=3.303),oliguria (24 h urine volume ＜ 400 ml) (OR=6.906),use of antiinflammatory drugs (OR=13.079) and multiple organ dysfunction syndrome (OR=17.778).Conclusions The incidence of AKI in hospitalized patients is not rare,among which both communityacquired and hospital-acquired AKI are mainly caused by pre-renal etiologies.All-cause mortality is lower in community-acquired AKI compared to that in hospital-acquired AKI and the independent risk factors are different between CA-AKI and HA-AKI.

Objective To investigate the characteristics of the cognitive impairment about attentional network among amphetamine-induced psychiatric disorders. Methods Amphetamine-induced psychiatric disorders ( n = 100) and normal controls ( n = 100) were assessed with Attentional Network Test(ANT) in the first week and the fourth week. Results Compared with the control group, the first ANT's response time was significantly increased, and the correct rate, orienting and executive control network were significantly reduced in Amphetamineinduced psychiatric disorders( eg:response time ( 867. 37 ± 272.24 ) ms vs ( 668.56 ± 136. 20 ) ms, correct rate (0.88 ±0.06 ) ms vs (0.88 ±0.06) ms ,orienting( - 217.86 ± 198.00 ) ms vs ( -59.67 ± 85.07 ) ms and executive control network ( 184.74 ± 66.61 ) ms vs ( 74.71 ± 50.77 ) ms, P ＜ 0.01 ), but the alerting network was higher ( ( 151.17 ± 198.27 ) ms vs (50.60 ± 67.47 ) ms). In the second ANT results, there was no significant difference between two groups. Compared with the first ANT results of amphetamine-induced psychiatric disorders, the second ANT had shorten response time ,that the correct rate, orienting and executive control network were significantly increased(P ＜ 0.01 ). Conclusion These results suggest that amphetamine-induced psychiatric disorders have impairment in cognitive function, but these impairment can be recovered within one month.

Objective To explore the underlying molecular mechanisms of estrogen induced apoptosis of synthetic vascular smooth muscle cells (VSMCs). Methods Cultured VSMCs on passage 3 were divided into three groups: 17?-estradiol (E-2) group, p38 inhibitor group (SB+E-2) and control group. With treatment for 72 hours,the apoptosis of cells was quantified by measuring the intracellular nucleosomes with ELISA; expressions of total p38, phospho-p38 and myocyte enhancer factor-2 (MEF2) were analyzed by Western blotting, with a confirmative immunohistochemical staining for MEF2. Results Compared with that of control cells, the rate of apoptosis in VSMCs grown in E-2 was significantly increased, with up-regulations of total p38, phospho-p38 and MEF2. These effects of E-2 were blocked in SB+E-2 group in which the rate of cell apoptosis and expression of p38 had no obvious change compared with that of control group, while the expression of p-p38 and MEF2 was decreased. Immunohistochemical staining showed that MEF2 was mainly located in cellular nucleus, and its expression was increased in E-2 group but decreased in SB+E-2 group. Conclusion Estrogen may induce apoptosis of synthetic VSMCs through p38 pathway-dependent up-regulation of MEF2.

ObjectiveTo explore the diagnosis and management of acute deep vein thrombosis(DVT) of lower extremity. Methods The clinical data of 96 patients with DVT were analysed retrospectively. ResultsThe diagnosis rate of DVT by vascular color ultrasounography was 97.8%, by MVC/SVO ratio combi ned with air plethysmagraphy was 97.2%, and by ECT was 100%. The MVO/SVC ratio, and diameter of calf and thigh in surgery group and in non surgery group showed significant difference in 7 days after operation (P

Objective To investigate the different effect among ropivacaine,bupivacaine,lidocaine on analgesia after harvesting grafts from the scalp in burn patients. Methods 84 patients who need harvesting grafts from the scalp after burn were divided in 4 groups random-ly(n=21). Patients in group C hypodermically injected with saline 200 mL were control,while patients in group R injected with 0. 05% ropi-vacaine 200 mL,group B with 0. 188% bupivacaine,and group L with 0. 1% lidocaine. Motor activity assessment scale( MAAS) and visual analogue scale(VAS) were made before anesthesia(T0) and 20 min,5 h,10 h after awake of patients. VAS were made focus on head and body in part. Vital signs were also monitored and recorded for assessment of security. Results All patients in 4 groups had passed the period of operation safely. Patients in group R have better VAS than other groups. Conclusion Low concentration ropivacaine hypodermically injec-tion of head is helpful to relieve the pain after harvesting grafts from the scalp.
