The receiver operating characteristic curve( ROC) was drew to predict dysglycemia,dyslipidemia and hyperurice?mia by body mass index( BMI) ,waist circumference( WC) ,waist?hip ratio( WHR) and BAI in different gender groups.Medcale soft was used to compare the area under the curve.Results According to the ROC analysis,in males the area under curve in the prediction of dysglycemia of BMI,WC,WHR and BAI was 0.553,0.556,0. 538,0.540(P<0.05),and 0.513,0.523,0.523,0.535 in females(P<0.05).The area under curve in the predic?tion of dyslipidemia of BMI,WC,WHR and BAI was 0.641,0.626,0.563,0.588(P<0.05) in males and 0.617, 0.613,0.597,0.587(P<0.05) in females.The area under curve in the prediction of hyperuricemia of BMI,WC, WHR and BAI was 0.685,0.665,0.609,0.577(P<0.05) in males and 0.730,0.708,0.656,0.649(P<0.05) in females,and BMI, WC of AUC were higher than BAI both in males and females(P<0.05).Conclusion BAI could be a predictor for the risk of metabolic disease,but less than BMI and WC.

Objective To explore the effect of cisapride combined with polyethylene glycol electrolytic solution on preoperative bowel preparation for patients receiving colorectal cancer operation. Methods One hundred and fifty-two patients received colorectal cancer opera-tion in our hospital from October 2010 to October 2014 were selected. Those who were treated with cisapride combined with polyethylene gly-col electrolytic solution for bowel preparation before operation were assigned to oberservation group(n=83),those who were treated with poly-ethylene glycol electrolytic solution for bowel preparation before operation were assigned to control group(n=69). The side effect after medi-cation, electrolyte concentration and incidence of incision infection between groups after operation were collected and compared. Results The incidence of nausea and vomiting was 7. 23% in observation group,which was significantly lower than 18. 84% in control group (χ2 =4. 64,P=0. 03). The difference of Na+,K+ and Cl- concentration between groups were not significant (t=1. 83,P=0. 07;t=0. 42,P=0. 68;t=1. 86,P=0. 07). The body temperature,leukocyte count and incidence of incision infection after operation in observation group were significantly lower than those in control group (t=2. 68,P<0. 01;t=3. 29,P<0. 01;χ2 =4. 90,P=0. 03). Conclusion Cisapride com-bined with polyethylene glycol electrolytic solution before operation can significantly decrease the incidence of gastrointestinal side effect after medicaiton and incision infection after operation and it is beneficial to recovery for patients with colorectal cancer operation.

Objectives To evaluate the effects of hypertonic-hyperoncotic solution (HHS) on cardiac function and extravascular lung water in children after open-heart surgery for congenital cardiac disease. Methods 50 children with congenital cardiac disease were randomly assigned to 2 groups. The HHS group received HHS (7.5% sodium chloride with 6% hydroxyethyl-stareh 200 kDa). The ISS group received isotonic saline solution (ISS 0.9% sodium chloride). Cardiac index (CI), extravascular lung water index (ELWI), stroke volume index (SVI), mean arterial pressure (MAP), and systemic vascular resistance index (SVRI) were measured. Immediately after sur-gery, patients were loaded either with HHS or with ISS (4 ml/kg). Sodium concentration, osmolality, thrombocyte count(TC), fibrinogen, and arterial blood gases were detected before operation, immediately after loading, 15 minutes, 1,4, 12, and 24 hours after the end of vol-ume loading. Hemodynamic parameters were recorded at the same time. The total amount of dobutamine required was documented. Results In HHS group, MAP, SVI and CI increased, and SVRI decreased significantly after the administration of HHS, compared with ISS group and before administration(P<0.01 or 0.05). Both CVP and HR were unchanged in both groups. In HHS group, ELWI decreased signifi-cantly, compared with before volume administration. But ELWI increased directly and remained elevated for 60 minutes after the administra-tion of ISS. Sodium concentration increased immediately after infusion of HHS. The postoperative need for infused dobutamine in the patients in HHS group was decreased, compared with ISS group (P<0.05). All patients left the hospital in a clinically sufficient state. Condu-sions A single infusion of HHS after cardiac surgery is safe. After cardiopuimonary bypass surgery, the administration of HHS increased CI by elevating SVI in combination with a decreased SVRI. ELWI significantly decreased, which suggest that HHS effectively counteracts, the capillary leakage.

Objective To investigate the expression of CD14/CD16 by monocytes and the anti-inflammatory effects of hypertonic saline plus dextran (HSD) in adult blunt trauma patients in hemonhagic shock. Method A total of 30 adult patients were eligible for inclusion in the study if they sustained blunt trauma from March to October 2007 and had at least one recorded episode of hypotension (systolic blood pressure ≤ 90 mm Hg) with clear evidence of blood loss (external or internal including the thorax, abdomen or retroperitoneum). Patients were excluded if they refused to participate, were admitted ≥ 6 hours after injury, were pregnant, or had chronic disease. The enrolled patients were randomly divided in a double-blinded manner into an HSD group which was administered 7.5% Nad plus 6% dextran - 70, and a control group which was administered 0.9% NaCl. A single 250 ml dose of either HSD or NaO was immediately administered to the patients in each of the two groups while they were in the emergency room. The primary outcomes were to measure the changes in CD4/CD16 expression by monocytes and the levels of anti-inflammatory cytokines, including tumor necrosis factor-alpha (TNF-α), interleukin (IL)-lra and IL-10. Patient demographics, fluid requirements, organ dysfunction, infection and death were recorded. Results A total of 28 patients were enrolled with no significant differences in their clinical measurements. Hyperosmolarity was modest and transient. HSD altered the shock-induced monocyte redistribution pattern by reducing the drop in the "classic" CD14 ++ subset and remarkably affecting the expansion of the "pro-inflammatory" CD14+CD16+ subsets. In parallel, HSD significamly reduced pro-inflammatory TNF-α production while increasing anti-inflammatory IL-lra and IL-10 production. Conclusions This human trial demonstrates that HSD has anti-inflammatory and immunologic properties for trauma patients in hemorrhagic shock. HSD exerts profound immunomodulatory effects, promoting more balanced pro-/anti-inflammatory responses and reducing post-traumatic complications. Therefore, it could be useful in attenuating post-trauma multiorgan dysfunction (MOD).

Objective To systematic evaluation the antiepileptic drug valproic acid and topiramate effects on body weight and plasma leptin levels.Methods By searching the Cochrane Library,PubMed,EMBASE,CNKI,VIP Chinese Scientific Journals Database and Articles Database (from building a database to August 1,2014),qualified RCT was chosen from those articles according to inclusion and exclusion criterias and evaluated their quality.Then the meta-analysis was performed by Rev Man 5.3.Results (1) A total of 70 documents retrieved for the evaluation,12 of the literatures could be incorporated into the Meta-analysis,including a total of 634 participants,9 literatures using valproate to treat epilepsy,4 literatures used topiramate.(2)Meta-analysis:compared with other drugs,valproic acid treatment increased body mass index and leptin level in patients with epilepsy,BMI combined MD=0.88(95％ CI:0.45-1.31),leptin level in the combined MD=0.58(95％ CI:0.07-1.09);compared with other drugs,topiramate affect body mass index and leptin level in patients with epilepsy had no statical difference,BMI combined MD=-0.02 (95％ CI:-0.62-0.58),leptin levels in the combined MD =-0.05(95％ CI:-0.31-0.20).Conclusion Antiepileptic drug valproic acid may increase patients' BMI and serum leptin levels,yet topiramate in do not have influence in patients BMI and serum leptin levels;more basic and clinical researches are needed to explore serum leptin levels and the exact therapy mechanisms of antiepileptic drugs for clinicians to select antiepileptic drugs.

Objective To investigate the difference of two models of respiratory failure in preterm infants with nasal continuous positive airway pressure(nCPAP)and nasal biphasic positive airway pressure (nBiPAP).Methods Comparative analysis of 81cases of premature infants with respiratory failure requi-ring respiratory support was needed.They were applied nCPAP and nBiPAP ventilation mode treatment.The use of breathing machine and total oxygen inhalation time,the number of treatment failures,the PEEP param-eters of the ventilator,the total number of recent complications and secondary infections were compared.Re-sults In the nBiPAP treatment group,the average time of noninvasive ventilation was(96.34±31.5)h,the total time of oxygen inhalation was(10.11 ±9.39)d,3cases of treatment failure,the incidence of severe complications was 5.56%(2/36),PEEP (4.08±0.73)cmH2O (1cmH2O =0.098kPa ).In the nCPAP group,the average time of noninvasive ventilation was(114.14±41.69)h,the total time of oxygen inhalation was(17.53±15.96)d,15cases were failed,the incidence of severe complications was 15.56%(7/45), PEEP(5.11±1.01)cmH2O.There were significant differences between the two groups(P﹤0.05).But there were no significant differences in infection control and patent ductus arteriosus (P ﹥0.05).Conclusion nBiPAP as one of the first choice treatment for premature infants with respiratory failure significantly better than nCPAP,as soon as the proper use can avoid invasive ventilation.
