Objective To evaluate efficacy of propofol compared with sevoflurane on inflammatory factor and liver function after hepatectomy. Methods 40 cases with hepatectomy were divided into propofol group ( P group) and sevoflurane group ( S group) , 20 cases in each group.The P group and S group respectively were given propofol or sevoflurane maintained anesthesia.The alanine aminotransferase( ALT) , total bilirubin( TBil) , aspartate amino transferase(AST), albumin(ALB), plasma tumor necrosis factor(TNF-α), interleukin-6(IL-6), interleukin-10(IL-10)and complication rate were compared between two groups.Results Postoperation 1d, 3d and 7d, the AST, ALT, and TBiL levels of S group were significantly lower than those of P group (P<0.05).There was no significant difference of ALB level between two groups.The plasma TNF-α, IL-6 and IL-10 levels of S group were significantly lower than those of P group (P<0.05).There was no significant differece of the rate of postoperative complications between S group and P group [6(30.0%) vs.10 (20.0%); χ2 =1.67, P >0.05].Conclusion Sevoflurane inhalation could effectively inhibit the plasma inflammatory cytokines secretion after hepatectomy, and promote liver function recovery, its effect is better than that of propofol.

Objective To analyze the effect of intrathecal injection of dexmedetomidine on the behavioral activity, pain degree and expression of protein kinase C in spinal dorsal horn of rat models of chronic neuropathic pain, and to investigate the analgesic mechanism of dexmedetomidine.Methods 75 healthy male rats were randomly divided into observation group, model group and control group, 25 rats in each group.Chronic sciatic nerve injury model was established in the observation group and model group.After modeling, intrathecal dexmedetomidine intervention was used in the observation group.The model group was treated with saline injection and there was no intervention in the control group.Before the modeling (BM)and at 3(D3), 5(D5), 7(D7), and 14 (D14)days after medicine administration, the behavioral capacity was evaluated by cumulative evaluation method and movement function evaluation, and the assessment of pain degree (mechanical withdrawal method and thermal withdrawal latency pain threshold detection method), PKC staining score (immunohistochemical SABC method), PKC mRNA assay (RT-PCR method) and PKC protein expression (Western blot) were conducted and the data were statistically analyzed.Results ① Before modeling, the behavior, the cumulative scores of motor function, MWT, and TWL showed no significant differences between the different groups (P>0.05).After modeling, the model group and observation group showed that the cumulative scores and motor function scores were increased significantly, MWT and TWL decreased significantly, and the changes in the observation group were significantly lower than those in the model group (P<0.05).After modeling, the cumulative scores, motor function scores, MWT, and TWL were significantly different between the groups (P<0.05).② The expression of PKC was negative in the control group and positive in the model group.In the observation group, after the initial establishment of model, the PKC was strongly positive, and along with the prolonged treatment, the PKC expression intensity was decreased, and only weakly positively expressed at 14 d.③ After modeling, the observation group and model group showed that the PKC mRNA and PKC protein expression levels were significantly higher than that of the control group (P<0.05).With the continuous drug administration, the PKC mRNA and PKC in the observation group were decreasing, and reached a level close to that of the control group at 14 d of drug administration.From the third day after modeling, at the same time points, the amount of PKC expression in the observation group was significantly lower than that in the model group (P<0.05).Conclusions Intrathecal injection of dexmedetomidine can improve the behavior of rat models with chronic neuropathic pain, and reduce the degree of pain.It may be related to the inhibition of protein kinase C expression in the spinal dorsal horn.

Objective To compare dual-energy X-ray absorptiometry T-score concordance between hip and lumbar spine, and to estimate the value of T-score of the hip for diagnosing osteoporosis in the elderly. Methods From September 2000 to May 2002, 123 males aged 60-89 years (average 72.0?7.4) and 137 females aged 60-88 years (average 67.3?6.1) were selected in the study based on the exclusion of subjects with apparent abnormalities affecting bone mass or taking medications which might affect bone metabolism. Detailed questionnaire included lifestyle factors such as smoking, drinking, exercise and dietary habits, etc. Radiographs of the thoracic and lumbar spine were taken. Patients' BMD were measured by DEXA (DMS, Challenger) at lumbar spine (L 2-4) and left hip in posterior-anterior projection. The right hip was scanned if patients had a history of fractures or any bone disease in the left hip. All data were statistically analysed using SPSS 8.0 system. Results The average T-scores of bone mineral density of the lumbar spine were higher than that of the hip in all male patients and in 65-, 85- age groups of female patients(P

Objective Health education was provided among driving coaches with overweight or obesity to improve their self-healthcare awareness.Methods Of 116 driving coaches from Changping District who underwent physical examinations and biochemical tests, 79 were confirmed to have overweight or obesity and received body weight management.Results Following 3 years of health management, 79 overweight or obese participants showed significant improvement in waist circumference ((93.5±8.4) vs (92.0±9.5) cm), systolic blood pressure ((130.8±12.4) vs (127.8±11.6) mm Hg, 1 mm Hg=0.133 kPa), diastolic blood pressure ((87.0±9.7) vs (85.6±9.3) mm Hg), high-density lipoprotein cholesterol ((1.1±0.4) vs (1.2±0.3) mmol/L), and glucose ((5.6±1.5) vs (5.4±1.6) mmol/L) (all P<0.05). Awareness of obesity-related knowledge showed significant difference before and after the intervention (P<0.05), although no changes of chronic diseases and abnormal measurements were found (P>0.05).Conclusion Overweight and obesity in middle-aged adults is of concern and needs long-term effective interventions.
