Objective To evaluate the effects of preoperative sleep disturbance on the consumption of propofol during the period of general anesthesia and postoperative sleep quality.Methods Sixty-five patients scheduled for elective thyroidectomy surgery under general anesthesia were enrolled in the study.According to the preoperative Pittsburgh Sleep Quality Index (PSQI) score,the patients were divided into sleep normal group (n =33) and sleep disorder group (n =32).Anesthesia was induced and maintained with propofol given by closed-loop target-controlled infusion (CLTCI).The consumption of propofol during the period of general anesthesia,postoperative sleep quality in the evening of surgery and at 24 h after operation,and the painful levels of the patients at 1 d and 2 d after operation were compared between two groups.Results The totalconsumption of propofol in sleep disorder group [(1 024.33 ±213.02)mg] was more than that in sleep normal group [(892.25 ± 242.30) mg] (P ＜ 0.05),and the dosage of unit surface area per minute of propofol in sleep disorder group [(4.94 ± 0.80) mg/(min · m2)] was also more than that in sleep normal group [(4.45 ± 0.96) mg/(min · m2)] (P ＜ 0.05).Each group suffered from bad sleep quality in the evening of operation,and got improvement one day later (P ＜ 0.05).The sleep quality in sleep disorder group was improved after general anesthesia (P ＜ 0.05).Conclusions Preoperative sleep disturbance increased the consumption of propofol in the general anesthesia.General anesthesia can improve the sleep quality of the patients who suffered from sleep disorder.

OBJECTIVE:To probe into the integrity of package insert for 75 kinds of commonly used antiinfective agents for injection in our hospital and to provide reference for rational use of antiinfective agents for injection. METHODS:According to Drug Description Specification and Management Regulation for Drug Description and Label,the terms included in package insert for antiinfective agents for injection were analyzed statistically. RESULTS:The package inserts for 75 kinds of antiinfective agents for injection were enrolled. The proportion of integral items were high while that of some terms related to clinic were low such as dosage and usage,medication for children,over dosage and skin test. The descriptions of PK,pharmacology,toxicdogy, ADR,et al. were very simple and different. CONCLUSION:It is suggested that items about over dosage and medication for special population should be detailed as well as usage so that package insert can guide rational use of drugs in the clinic.

Purpose:To investigate the cyclooxygenase-2(COX-2) expression in gastric carcinoma and investigate the effects of COX-2 expression on P-glycoprotein. Methods:The expression of COX-2 and P-glycoprotein was examined by immunohistochemical staining in 48 cases of gastric carcinoma and 10 cases of normal gastric tissues. Results:There was no positive signal of COX-2 detected in normal gastric tissue. The positive expression rate of COX-2 was 60.4 %(29/48) in gastric carcinoma. The expression of COX-2 was correlated with TNM stage and lymph node metastasis (P

To observe the effects of paeoniflorin and total flavones extracted from Qixue Bingzhi Recipe on proliferation of vascular smooth muscle cells (VSMCs) cultured in endothelial cell conditioned medium (EC-CM) induced by oxidized low-density lipoprotein (ox-LDL) and the expressions of platelet-derived growth factor and its receptor genes.

BACKGROUND: Studies are very few regarding the specific reaction of bone marrow mesenchymal stem cells (BMSCs) to activated microglia. Moreover, it remains unclear how MSCs maintain dopaminergic neuronal survival under specific microenvironment.OBJECTIVE: To explore the effect of BMSCs stimulated by activated microglia on dopaminergic neuron survival.METHODS: BMSCs were isolated from Wistar rats by attachment method, and in vitro cultured; microglia was activated, and dopaminergic neurons were cultured by enzyme digestion method. The experiment included 5 groups: BMSCs, microglia, lipopolysaccharide (LPS)+microglia; BMSCs+LPS+microglia groups, in which the dopaminergic neurons were cultured with corresponding culture medium; the dopaminergic neurons alone group was cultured with 10% fetal bovine serum+ DMEM/F12. The effect of different microenvironment on dopaminergic neuron survival and gliocyte-derived neurotrophic factor released from BMSCs were detected by immunofluorescence technique.RESULTS AND CONCLUSION: The release of gliocyte-derived neurotrophic factor in groups involving BMSCs was greater than corresponding control group. Tyrosine hydroxylase immunofluorescence showed that neuronal survival of dopaminergic neurons alone group was 15%, microglia group was 10%, LPS+microglia was 5%, but BMSCs+LPS+microglia group was 28%, significantly greater than the other groups (P < 0.05). In addition, survival of in vitro cultured dopaminergic neurons was decreased with increasing culture duration, but the survival of dopaminergic neurons in group involving BMSCs was significantly greater than corresponding control group. This indicates that microglia activation stimulated BMSCs to upregulate gliocyte-derived neurotrophic factor to prevent dopaminergic neurons from toxic injury, and inhibit delayed death of dopaminergic neurons.

Objective To explore a separation and culture method of human adipose-derived stem cells(ADSCs) suitable for the clinical application .Methods The non-enzymatic method and the collagenase digestion method were adopted to isolate and culture the cells from the human adipose tissue in the individuals with liposuction .The characteristics of isolated mesenchymal stem cells were comparatively analyzed .Results The required time in the non-enzymatic method was one third of that in the collagenase di-gestion method and the cellular morphology ,reproductive capacity ,immunophenotype and differentiation potential of the isolated cells were consistent to those isolated by the collagenase digestion method .Conclusion The no-enzymatic method may isolate and culture ADSCs from the adipose tissue in the individual with liposuction ,which is a safety and reliable isolation and culture method of human adipose tissue-derived stem cells suitable for clinical application .

Objective To explore the impact of total parathyroidectomy(tPTX)on carotid-femoral pulse wave velocity(cfPWV)in hemodialysis patients. Methods A total of 35 patients undergoing hemodialysis with refractory secondary hyperparathyroidism and treated with tPTX were studied. Before tPTX and 1 year after the oper-ation,cfPWVwas measured and hepatic and renal function,serum calcium,serum phosphorus,intact parathyroid hormone and hemoglobin were measured. The impact of tPTX on cfPWV in hemodialysis patients was analyzed. Results Serum calcium,serum phosphorus and intact parathyroid hormone decreased(P < 0.01),while hemo-globin and serum albumin increased(P < 0.01)and cfPWV decreased 1 year after the operation,which showed statistical significance(P<0.01). The cfPWV of the patients with tPTX was still higher than that of healthy indi-viduals(P<0.01). Conclusion tPTX can effectively reduce cfPWV in hemodialysis patients with refractory sec-ondary hyperparathyroidism.
