Objective To observe the effect of intensive insulin therapy (ⅡT) on prognosis of severe chest trauma (SCT) pateints.Methods 42 consecutive patients were randomly assigned to 2 groups:ⅡT group (n =21) and the conventional insulin therapy group (CIT group,n =21).Blood glucose was maintained at the level of 4.4 -6.1mmol/L in ⅡT group,and 10.0 -11.1mmol/L in CIT group.The 2 groups were observed in terms of fatality rate during hospital stay,infection rate,the duration of mechanical ventilation,ICU stay length,pleural drainage day and count of neutrophils.Results No death or hypoglycemic reaction happened during hospitalization.Compared to CIT group,infenction rate,mechanical ventilation time,ICU stay length,and the time required for white blood cell to resume normal in ⅡT group were decreased significantly ( P ＜ 0.05 ).The difference had no statistical significance between the 2 groups in duration of pleural drainage and incidence of hypoglycemia (P ＞ 0.05).Conclusion ⅡT improves the short-term prognosis of SCT patients.

Objective To analyze the etiology and clinical characteristics of infectious mononucleosis-like syndrome (IMLS).Methods Eighty-seven children with IMLS in a hospital from January 2006 to September 2013 were per-formed pathogenic detection,then clinical features were summarized and analyzed.Results The top 5 pathogens in IMLS were Mycoplasma pneumoniae (MP,n=20 ),cytomegalovirus (CMV,n=13),simplex herpes virus(HSV, n=11),Chlamydia (CP,n=11),and parvovirus B19 (Hpv B19,n=9 ),clinical manifestations of all kinds of dis-eases were similar,but the occurrence rates were slightly different.MP infection were mainly fever,hepatospleno-megaly,and lymphadenopathy,and most were associated with respiratory complications(including laryngitis,bron-chitis,and pneumonia),CMV infection were also showed fever and hepatosplenomegaly,but the latter was more ob-vious;rubella patients didn’t appear skin rash,but the other symptoms were obvious.Conclusion Etiologies of in-fectious mononucleosis-like syndrome are varied,MP infection is most common,the next is CMV.Pathogens should be ascertained to provide theoretical basis of treatment.

Objective To observe the clinical efficacy of Ningmitai capsule combined with Tolterodine in the treatment of overactiver bladder after transurethral resection of the prostate(TURP).Methods 63 TURP patients with bladder disease (OAB) in our hospital from October 2012 to October 2012 were selected and randomly divided into a treatment group (n=32) and a control group (n=31). From the date of operation, the control group was treated with tolterodine 2 mg, 2 times a day, while the treatment group was additional treated with Ningmitai capsule 4mg, 3 times a day based on the control group. All patients stopped to take medicine 5 days after catheter removal. The pain frequency and duration of bladder spasm after TURP in catheterization period and the urine volume per time, the number of urgent incontinence, and the number of urgent micturition average day in automatic micturition period were scored by OABSS.Results The number of bladder spasm in the first postoperative day(3.5 ± 0.5vs.4.4 ± 0.8,t=2.650), the second day(1.5 ± 0.9vs.1.8 ± 0.2,t=2.350) and the third day (0.4 ± 1.6vs. 1.1 ± 1.8,t=2.210) of the treatment group were all less than the control group (P>0.05). The 24 h average frequency of urination after catheter removal (6.2 ± 1.3vs. 9.4 ± 1.8,t=2.710), the average number of nocturia (1.5 ± 0.4vs. 3.9 ± 1.0,t=2.580), the average number of 24h urinary urgency (1.1 ± 0.3vs. 3.2 ± 0.8,t=2.660), the average number of incontinence in 24 h (0.5 ± 0.2vs. 2.4 ± 0.6,t=2.700) and OABSS total score  (4.6 ± 1.2vs. 6.9 ± 2.1,t=2.470) of the treatment group were all better than the control group (P<0.05). Conclusion Ningmitai capsule combined with tolterodine in the treatment of overactiver bladder after TURP has significant clinical effect, helping patients recovery and improving quality of life.

Objectives To explore the relevant factors of liver X receptor (LXR) and lipid metabolism in school-age chil-dren with obesity. Methods A total of 80 obese children were selected by indexes of physical growth from pupils in Grades 1-6, aged 7-14 years from June 2011 to October 2011. Fifty-one age and sex matched children with normal BMI were chosen as nor-mal controls. The metabolic indexes including aspartate transaminase (AST), alanine aminotransferase (ALT), glutamyl transpep-tidase (GGT), total cholesterol (CHOL), triacylglycerol (TG), high density lipoprotein cholesterol (HDL-C), low density lipopro-tein cholesterol (LDL-C) and expression of LXR were detected in fasting blood. Results The expression level of LXR in obese children (9.14 ± 1.15) was higher than that in control children (2.84 ± 3.68) with significant difference (t=4.55,P=0.000). Eighty percent (80%) of obese children were LXR>1 (64/80) which was higher than that of control children (23/51, 45.1%), and signifi-cant difference was found between the two groups (χ2=17.01, P=0.000). Compared to controls, the levels of AST, ALT, GGT, CHOL, TG and LDL-C were higher while the level of HDL-C was lower in obese children (P<0.05). The correlation analysis found that AST, ALT, CHOL, LDL-C and BMI were positively correlated with LXR (r=0.18~0.26,P<0.05). Logistic regression ana-lysis showed that AST≥40IU/L (OR=1.076), ALT≥40IU/L (OR=1.036), CHOL≥5.20 mmol/L (OR=2.038), LDL-C≥3.36 mmol/L (OR=2.176) and BMI≥18.9 kg/m2 (OR=1.131) were risk factors for LXR>1 (P<0.05). Conclusions Obesity in school-age chil-dren can up-regulate the expression of liver X receptor and cause liver damage and abnormal lipids metabolism.

Objective To evaluate the efifcacy and safety of Xiyanping in the treatment of hand-foot and mouth disease. Methods Based on the principles and methods of Cochrane systematic reviews, Cochrane Library, PubMed, Medline, Chinese Bio-medicine Database (CBM), China Journal Full-text Database (CNKI), VIP database and Wanfang database were searched. All of the randomized controlled trials (RCT) of Xiyanping versus ribavirin were included. The data were extracted and evalu-ated by two reviewers independently. Risk assessment tool was used to assess the risk of bias and software Revman5.0 was used for meta-analysis. Results Twenty-four RCT and 3314 patients were included. Comparing to ribavirin, Xiyanping showed better therapeutic outcomes regarding to total effective rate, durations of fever and rash elimination (RR=1.17, 95%CI:1.12~1.23;MD=-1.56, 95%CI:-2.10~-1.02;MD=-1.41, 95%CI:-1.90~-0.93). Side effects were rare in both groups and could be recovered after drug withdrawal. Conclusions The current evidence suggests that Xiyanping is superior to ribavirin in the treatment of hand-foot and mouth disease.

Objective To evaluate the influence of cytochrome P450 (CYP2C9 and CYP4F2) polymorphisms on anticoagulant intensity of warfarin after cardiac valve replacement.Methods A total of 136 patients tak ing warfarin after cardiac valve replacement were identified and classified into 4 groups:CYP2C9 wild type group (CYP2C9*1*1),CYP2C9 mutated type group (CYP2C9*3),CYP4F2 rs2108622 wild type group (CC) and CYP4F2 rs2108622 mutated type group (CT or TT).The patients' baseline data,initial dose of warfarin and base INR measurement resuhs were recorded and then the follow-up was conducted.The initial administration of warfarin to INR standard time for the first time,total amount of warfarin and the average daily amount were recorded.Results Patients carrying CYP2C9* 1* 1 had increased time to reach INR target value for the first time (P ＜ 0.05);and the total warfarin doses and average daily dose when INR reached target value were higher than those carrying CYP2C9*3 (P ＜ 0.05).When compared with those in two wild type groups,patients carrying CYP2C9 and CYP4F2 rs2108622 mutated type needed the shortest time when INR reached target value for the first time,and the total warfarin doses and average daily dose when INR first reached target value was the lowest,which showed significant difference (P ＜ 0.05).And when compared with CYP2C9 mutated type group,the INR average time to reach the first target was shortened and the total warfarin dose of patients carrying CYP2C9 and CYP4F2 rs2108622 mutated type was lower (P ＜ 0.05).Conclusion The gene polymorphisms of CYP2C9 and CYP4F2 are significant hereditary factors influencing warfarin dose.Detection of CYP2C9 and CYP4F2 genotypes prior to medication and predicating warfarin dosage may result in lower incidence of over-anticoagulation and reduce the dosage-adjusting time of warfarin.
