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.

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

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.

A biomedical entity association evolution network was constructed by mining the implicit associations in PubMed-covered literature, which can help scientific researchers to form new scientific hypotheses, to analyze the topological features of associated network, to study the scientific literature-enriched knowledge structure, associa-tions, development rules, to introduce new visual angles and methods for literature-based knowledge discovery, and to improve the knowledge discovery efficiency.

To explore the influence of glucose level of 75 g oral glucose tolerance test ( OGTT ) druing pregnancy on delivery of large for gestational age infants. This research selected 790 cases of patients diagnosed as gestational diabetes mellitus( GDM) , 478 cases of pregnant women diagnosed as normal glucose tolerance( NGT) from Affiliated Hospital of Jining Medical University in 2014 and followed up until they delivered. Single live births were selected, risk factors which had influence on offsprings, birth weight were analysed. GDM group had significantly higher rate of delivering large for gestational age(LGA)infants than that of NGT group(47. 30% vs 31. 30%, P<0. 05). Adjusting for confounding factors, it suggested that 2 h plasma glucose level of 75 g OGTT was an independent risk factor for the delivery of LGA infants, and 1 mmol/L glucose increment in 75 g OGTT 2 h plasma glucose level, mayincreasetheriskofLGAby29%(OR=1.29,95%CI1.05-1.58,P=0.02). The2hplasmaglucoselevelof75 g OGTT is an independent risk factor for delivery of LGA infants.

Objective To establish experimental radioactive wound model in miniature pig and observe its pathological changes in order to carry out in vivo study of radioactive wound-related diseases.Methods According to the random number table,eight adult Bama miniature pigs were divided into four groups after being anesthetized:normal control and experiment groups exposed to 0,10,20 and 30 Gy respectively using the X-ray linear accelerator.Then a puncher was use to prepare full-thickness skin defects (4 cm in length) in the irradiation site.Wound samples were collected every other week to observe wound healing.RT-PCR was used to measure expressions of tumor necrosis factor (TNF)-α and transforming growth factor (TGF)-β in wound tissues 35 days after irradiation.At the same time,Western blot was utilized to detect expressions of CD31 and collagen Ⅰ.HE staining was applied to observe histopathological changes of the radioactive wound.Results Skin wounds in normal control group healed in 35 days.Whereas in 20 and 30 Gy experiment groups,the wounds were not healed in 63 days and the healing rate was gradually weakened with the irradiation dose increasing.Expression ratio of TNF-α mRNA was 0.315 ±0.007 in normal control group,0.984 ±0.211 in 10 Gy experiment group,1.140 ±0.088 in 20 Gy experiment group,and 0.471 ±0.030 in 30 Gy experiment group.Expression ratio of TGF-β mRNA was 0.402 ± 0.018 in normal control group,1.707 ± 0.147 in 10 Gy experiment group,1.933 ± 0.078 in 20 Gy experiment group,and 0.968 ± 0.084 in 30 Gy experiment group.Expressions of TNF-α and TGF-β mRNA were significantly increased in 20 Gy experiment group compared to normal control group (P ＜ 0.05).Expressions of CD 31 and Collagen Ⅰ protein were inhibited in 20 Gy experiment group compared to normal control group (P＜0.05).Epithelialization and granulation tissue regeneration in 20 Gy experiment group were impaired.Conclusion An irradiation wound model in Bama miniature pigs can be efficiently and effectively simulated using the 20 Gy X-ray irradiation combined with full-thickness skin defect,and can be used to study the pathophysiology and therapeutic intervention of radioactive wound-related diseases in vivo.
