Objective To investigate the effects of different body temperatures on the neuromuscular block induced by different doses of cisatracurium in rabbits. Methods Seventy-two healthy New Zealand white rabbits of both sexes weighing 2.0-2.2 kg were randomly divided into 3 groups (n=24 each): hypothermia group (L), normothermia group (N) and hyperthermia group (H). The rectal temperature was set at 34.5℃, 38.5℃ and 41.8℃ in group L, N and H respectively. Each group was further divided into 4 subgroups (n=6 each) receiving intravenous cisatracurinm 0.33, 0.66, 0.99 and 1.32 mg/kg respectively after rectal temperature was stabilized for 20 min. The animals were anesthetized with iv 20% methane 1 g/kg, tracheostomized and mechanically ventilated (VT 12 ml/kg, RR 60 bpm, I:E = 1:2;FiO2 100% ). TOF was monitored. The onset time, the duration of action (from the end of cisatracurium injection to the recovery of T1 to 5%, 25% and 95% of control height) and recovery index (recovery of T1 from 25% to 75% of control height) were recorded. MAP, HR and rectal temperature were recorded at 5 min before alteration of the body temperature, at 2 min before and 5, 10, 30, 60 and 90 min after administration of cisatracurium. Results (1) With the same dose of cisatracurium the onset time and duration of action were significantly shorter in group H, longer in group L and recovery from N-M block faster in group H, slower in group L as compared with group N. (2) At the same body temperature the onset time was significantly shortened and the duration of action and recovery were significantly prolonged as the dose of cisatracurium increased. (3) There was significant difference in the effect of interaction between different doses of cisatracurium and different temperatures on the onset time. (4) With the same dose of cisatracurium MAP was significantly decreased in group H, increased in group L, while HR was significantly increased in group H, decreased in group L. Conclusion The neuromuscular blocking effect of cisatracurium is decreased when the body temperature is increased and vice versa. The neuromuscular blocking effect of cisatracurium (0.33-1.32 mg/kg) is dose-dependent at the same body temperature. There is interaction between the two factors.

Objective To explore the relationship between the levels of plasminogen activator inhibitor-1(PAI-1) and type 2 diabetes mellitus (T2DM) with vascular complication. Methods The plasma concentrations of PAI-1 were determined by ELISA in 34 control subjects (Control group) and 134 diabetic patients (T2DM group),which were further subdivided into 4 subgroups based on body mass index (BMI) and with or without macro-vascular complication. Results The PAI-1 levels in four diabetic subgroups were significantly increased compared with those of the control. The PAI-1 level in T2DM with macroangiopathy was significantly higher than that in T2DM patients without macroangiopathy (P

Objective To investigate the effect of early screening and intervention on congenital hypothyroid-ism.Methods Thyroid stimulating hormone (TSH),three thyroid stimulating hormone (T3 )and thyroid hormone (T4 )were screened in 72h after birth,and thyroid ultrasound examination.All the patients were treated with the treat-ment of the left -to -thyroid hormone,0 -6 months medication dose 25 -50g/d,6 -12months medication dose 50 -100g/d,1 -3months medication dose 75 -100g/d.Serum TSH was reviewed every three months in the age of 1 years, 2 -3 years old every six months to review the serum TSH.Results The mean value of TSH in children with congeni-tal hypothyroidism was (68.7 ±15.3)mU /L.The mean value of T4 was (42.4 ±13.1)nmol/L.100 cases of chil-dren,including 38 cases of primary congenital hypothyroidism,transient congenital hypothyroidism in 62 cases.Ultra-sound examination showed primary congenital hypothyroidism were developmental abnormalities,and abnormal absence of a total of 18 cases (47.4%),Abnormal blood flow in 15 cases (39.5%);No abnormalities were found in the ultrasound examination of the transient congenital hypothyroidism.Before treatment,TSH in children with congenital hypothyroidism was significantly higher than that in the control group[(68.7 ±15.3)mU /L vs (4.6 ±1.1)mU /L], T4 was significantly lower than the control group[(42.4 ±13.1)nmol/L vs (124.4 ±45.5)nmol/L],the differences
were statistically significant (t =22.867,16.058,all P <0.05);After treatment,the TSH of the children was signifi-cantly decreased[(5.3 ±1.1)mU /L vs (68.7 ±15.3)mU /L],and the T4 was significantly increased[(114.5 ± 35.4)nmol/L vs (42.4 ±13.1)nmol/L],compared with before treatment,the differences were statistically significant (t =41.331,19.101,all P <0.05 ),but compared with the control group,there were no significant differences between TSH and T4 (all P >0.05).After 1 -3 years follow -up observation,children with Gesell development scale test showed that children with adaptability,large movements,fine movements,language and social skills to reach the normal level.Conclusion Early screening and treatment of the patients with congenital hypothyroidism is beneficial to the rehabilitation of the patients with congenital hypothyroidism.

Objective: To investigate the optimal culture conditio ns for adipose tissue-derived stromal cells(ADSCs) and for the induction of these cells to differentiate into osteogenic cells. Methods: ADSCs were cultured with routine methods,bFGF at 20 ng/ml was added into the medium and the proliferative of ADSCs was examined by cell counting. 0.1 ?mol /L of dexamethasone,10 mmol/L of ?-glycerophosphate and 50 ?mol/L of ascorbic acid were adapted to induce the cells to differentiate into osteogenic cells, ADSCs were identified by immunocytochemistry and differentiated osteogenic cells were identified by alkaline phosphatase(AP) staining and immunocytochemistry. Result: A population of ADSCs could be isolated from adul t human adipose tissue,the cells were fibroblast-like and could be maintaine d in vitro for extended periods with stable population doubling.The cells w ere expanded as undifferentiated in culture for more than 10 passages, indicati ng their proliferative capacity.bFGF stimulated the cell proliferation.Dexameth asone,?-glycerophosphate and ascorbic acid induced (40?8.6)% of ADSCs to ex press alkaline phosphatase(AP) ,(35?10.6)% of AP positive ADSCs were found to be collagen I positive. Calcification plaques were occasionally found in the cul tures. Conclusion:The data support the hypothesis that adu lt human adipose tissue contains stem cells capable of diffferentiating into ost eogenic cells.

Objective To intervene and appraise the health literacy of diabetic patients entering contracts with family doctors in pilot communities,and learn the effect and feasibility of health literacy management by family doctors for diabetic patients.Methods By means of community intervention study and questionnaire survey,560 diabetic patients as mentioned above in Shanghai were subject to a baseline assessment on their health literacy,followed by management and routine follow-up on their diabetic health literacy.At the end of six months of comprehensive intervention,their health literacy was appraised again to observe the effects of such management.Results Six months of guidance and management found the average scoring of the health literacy of these patients 23.46 over the baseline,an increase of 36.8% of the patients in their compliance of the four basic diabetic diet behaviors,and an increase of 27.8% of them in regular and quantitative exercises.Conclusions It is feasible for community family doctors to carry out the health literacy management for diabetic patients contracted,and health literacy management can change the awareness and behaviors of such patients to some extent.

Objective\ To study the influence of long-term quality of life in MHD patient after their family numbers have received home-nursing education Methods 49 cases of MHD were divided into two groups randomly: the observe groups(n=24),and the control groups(n=25).Both groups were received routing treatment with health education,while the family members of observation groups were also guided with home-nursing education.After one and five years′ treatment,the index of quality of life were compared with SF-36 respectively. Results The quality of life in observation groups was significant higher than that of control group(after one year P

AIM: The aim of the present study is to investigate changes of five biochemical markers of bone turnover during the formation of ovariectomized rat model. METHODS: Three-month-old female SD rats were divided randomly into ovariectomized (OVX) group, sham-operated (sham) group and control group. Five biochemical markers of bone turnover levels, including serum osteocalcin (OC), total alkaline phosphatase (ALP), bone-specific alkaline phosphatase (BALP), tartrate-resistant acid phosphatase (TRAP) and hydroxyproline (HYP) were measured before and at 1, 1.5, 2, 2.5, 3 and 4 months after surgery. The right proximal tibias of rats were excised at the same time point for histopathological observation. RESULTS: Serum OC, ALP, BALP, TRAP and HYP levels in OVX group were significantly higher than that in sham group. As regard to the time of peak level arrived, the sequence of changes was as follows: TRAP/HYP→OC→ALP/BALP. There was a significant positive correlation between five markers. The pathological changes of trabecular bone in OVX group were only observed 3 months after surgery. CONCLUSION: The results suggest that postmenopausal osteoporosis has a high bone turnover rate. During the formation of ovariectomized rat model, changes of bone resorption markers precede changes of bone formation markers. Serum OC, ALP, BALP, TRAP and HYP are sensitive to evaluate the bone loss in the earlier stage of postmenopausal osteoporosis.

Objective To investigate the effect of psychological abuse in childhood on the personality of undergraduates with depression as well as its possible mechanism, and thus provide scientific evidence for the intervention of depression in undergraduates. Methods Particinants were 733 undergraduates from a university in Henan Province. They were surveyed with Center for Epidemiological Studies-Depression scale (CES-D), childhood experience of care and abuse questionnaire (CECA. Q) and Eysenck personality theory (EPQ). Results the correlation between maternal antipathy and introversion-extroversion of personality;psychological abuse in childhood had apparently positive correlation with the depression in undergraduates (r = 0. 257, r = 0. 304, r =0. 243, P＜ 0. 01) and that of childhood maternal neglect to psychoticism (β = 0.206, P＜ 0.01) were positive and significant. The standard regression coefficients of paternal neglect to introversion-extroversion (β= -0. 143, P＜0. 01)were negative and significant . The scores of childhood paternal antipathy and maternal antipathy explained that childhood paternal antipathy had indirect effect via adulthood neuroticism on the depression in undergraduates,furthermore, the indirect effect demonstrated 59.8% of the total effect. Conclusion This study suggests that the personality of undergraduates with depression is affected directly by psychological abuse in childhood, and adulthood personality may mediate the relation between childhood psychological abuse and adulthood depression.
