Objective To investigate the expression of insulin-like growth factor-Ⅱ( IGF-II ) and its mRNA in human placenta and to evaluate its role in the pathogenesis pregnancy induced hypertension (PIH). Methods The cellular distribution of IGF-Ⅱin normal and PIH placenta was determined by immunohistochemistry. Trophoblasts were digested,separated,and purified from placenta. IGF-ⅡmRNA expression in trophoblasts was detected by RT-PCR. The mean density was determined by image analysis technique. Results (1) IGF-Ⅱwas mostly found in syncytiotrophoblast,cytotrophoblast and amnio-chorion. The strongest immunoreactivity was observed in the syncytiotrophoblast and cytotrophoblast. (2)The mean density of PIH placenta (0.324?0.042) was significantly lower than that of normotensives (0.360?0.072,P

Objective To establish a mathematical model for describing and predicting the effectiveness of physical therapy on lumbar disc hernation(LDH).Methods Daily comprehensive physical therapy interventions including lumbar traction,mobilization and physical agents were administered to 31 LDH patients for 10 sessions.A visual analogue scale was used to measure the pain intensity before each session.The logistic curve model was used in the regression analysis.The first 2 to 9 pain measurements were involved in different predictive models,and the predictive results were compared among different models.Results In regression analysis,the global R2 was 0.719.In predicting analysis,the more measurements involved in the predictive model,the more effective the prediction.The predictive power was low when the model included less than 4 measurements.the prediction power was high when more than 5 measurements were used in the model.Conclusion The logistic model can describe and predict the effectiveness of multiple physical therapy on LDH patients.

Objective To investigate the effects of comprehensive geriatric assessment (CGA) and health intervention on outcome in discharged patients.Methods Discharged patients in geriatric ward from May to July 2012 were randomly assigned to control (n=36) and intervention (n=36) groups.Patients in the two groups were given comprehensive geriatric assessment (CGA) before discharging from hospital.Both groups were followed up for 3 months.Patients in intervention group received health intervention when leaving hospital,at 1 week,3 weeks and 3 months after discharge from hospital,while patients in control group were not given any intervention.The comprehensive illness condition (MCIRS-G),ability of daily life (ADL and IADL),rehospitalization and survival rate were compared between the two groups 3 months after the intervention.Results After 3 months,the scores of MCIRS-G,ADL and IADL were significantly better in intervention group than in control group[(29.06±4.51) vs.(33.09±4.34),(75.69±16.57)vs.(63.86±19.37),(11.72±3.20) vs.(9.77±2.52),respectively,t=3.84,2.77,2.85,all P=0.01].The total times ofreadmission and readmission length were less in intervention group than in control group [3 vs.17,x2 =8.79,P=0.02; (1.94±6.68) days vs.(8.81±14.09) days,t=2.64,P=0.01].There was no difference in survival rate between the two groups [100% (36/36) vs.97.2% (35/36),x2=1.01,P=0.30].Conclusions Comprehensive geriatric assessment and health intervention can alleviate symptoms and improve the ability of daily life.

Objective To investigate the social support of the elderly hospitalized individuals and its relationship with outcomes and to study its influential factors.Methods The elderly in-patients aged>65 years old who were treated from April to June 2012 in Geriatric Department were recruited.The comprehensive geriatric assessment (CGA) that included social support scale (SSRS) was used.According to SSRS,the patients were assigned to the lower or higher score group.The participants were followed up for 1 year,and 12-month mortality and re-hospitalization were recorded.Student's t test,Chi-square test and multiple logistic regression were used for data analysis.Results The total score of social support was 26.58±8.99,which was significantly lower than the national norm (34.56±3.73,t =-7.52,P<0.05).Those with advanced age,less household,depression,insufficient ability of daily life and instrument daily life showed relatively lower SSRS (t values were-2.54,8.22,-6.61,6.72 and 6.95,respectively; all P<0.05).The patients with no spouse also got less social support (x2 =8.58,P<0.05).At 1 year,no significant difference of re-hospitalization and mortality was found between the two groups (x2 values were 1.94 and 3.28,respectively; both P>0.05).In multiple logistic regression analysis,fanily member,characteristics and living ability were the major influential factors of social support.Conclusions Medical staff should pay more attention to the elderly hospitalized patients and offer them sufficient social support to improve their quality of life.

Objective To explore the effective using cycle of Lu Wofu lubricant preservation with different cleaning methods,and provide basis for change time of lubricant preservation.Methods 20 000 bricant was ensured under sterile conditions.400 pieces of the same equipment were extracted from surgical instruments every day,and they were randomly divided into the manual cleaning group and the mechanical cleaning group with 200 pieces in each group,each group adopted manual cleaning and mechanical cleaning.The Lu Wofu lubricant was reused and preserved for one week.Lubricant preservation was extracted and sent to do bacterial culture with fixed people,time and quantity.Results of two groups were compared.Results The qualified rate of the two groups at 24-hour was 100%,at 48-hour the manual cleaning group was 92%,the mechanical cleaning group was 77%,at 72-hour the manual cleaning group was 81%,the mechanical cleaning group was 19%,above 72 hours; both the manual cleaning group and the mechanical group was zero.Over 48 hours in the mechanical group and above 72 hours in the manual cleaning group appeared more than 10 million bacterial colonies.There was significant difference between the two groups.Conclusions The effective using cycle of Lu Wofu lubricant preservation was 72 hours for manual cleaning and 48 hours for mechanical cleaning,the manual cleaning delays one day over mechanical cleaning to change lubricant,which can reduce the waste of resources and cost savings.

OBJECTIVE To analyze the nosocomial infections among dead cases with cancer and explore the relationship between death and nosocomial infections.METHODS Totally 309 dead cases with cancer were investigated and analyzed in 2004-2005.RESULTS From them 64 with 72 times accompanied by nosocomial infections(20.71%,23.30%),the rate was 5.85 times higher than the total nosocomial infection rate in the hospital.Of 64 cases with nosocomial infections,48(75%) were led to death directly by nosocomial infections.The average hospitalization time of these 64 dead cases with nosocomial infections was 63.94 days,which was 20.98 days longer than the whole average hospitalization time(29.21 days).Cases with tumors related to immune system were more often accompanied by nosocomial infections than with other tumors(P

Objective To observe the change of learning and memory quality and the expression change of GABAR1 and NMDAR2B in aged SD rat cerebral temporal lobe by propofol injection and discuss the influence that may be caused by propofol.Methods Aged male sd rats were randomly divided into three groups,each group of 20.Propofol intraperitoneal injection was implemented to groups P1 and P7 according 50 mg/kg and maintained anesthesia for 3 hours.The same dose of emulsion was given to control group. Morris water maze test was done in the first days and the seventh days after intraperitoneal injection.Then the left temporal lobe was gathered and the mRNA transcription and protein expression of GABAR1 and NMDAR2B were detected by FISH and Immunofluorescence technique.Results Compared with control group,the latent time of group P1 was significantly prolonged and the numbers of passing through the target frequency were decreased significantly (P <0.05).Group P7 had no significant differences.The mRNA transcription and protein expression of GABAR1 in group P1 were increased significantly and the mRNA transcription and protein expression of NMDAR2B in group P1 were decreased significantly (P <0.05 ). Group P7 had no significant differences.Conclusion The short-term memory of brain declined after propofol was used.This may be related to the function of temporal lobe.The mechanism may be related to the up regulation of GABAR1 and the down regulation of NMDAR2B simultaneously.
