Objective To investigate the correlation between serum uric acid (SUA) level and early-phase insulin secretion in subjects with normal glucose regulation (NGR).Methods Totally 367 community NGR residents confirmed by a 75g oral glucose tolerance test were enrolled.The insulin resistance index (HOMA-IR) and the early-phase insulin secretion index after a glucose load (ΔI30/ΔG30) were used to estimate the insulin sensitivity and the early-phase insulin secretion, respectively.The subjects were divided into 4 groups according to the SUA level quartiles.Differences in early-phase insulin levels, ΔI30/ΔG30, and HOMA-IR were compared among the 4 groups.Results Age, BMI, waist circumference, systolic blood pressure, diastolic blood pressure, fasting insulin (FINS), 30 minutes postprandial insulin (30 minINS), 2 hours postprandial insulin(2hlNS), HOMA-IR and TG levels increased across the rising categories of SUA levels, while the HDL-C was decreased across the SUA groups (P ＜ 0.01).The SUA level was positively correlated with age (r =0.157, P ＜ 0.01), BMI (r =0.262, P ＜ 0.01), waist circumference(r =0.372, P ＜ 0.01), systolic blood pressure (r =0.200, P ＜ 0.01), diastolic blood pressure(r =0.254,P ＜ 0.01) , 30 minutes postprandial plasma glucose(r =0.118 ,P =0.023), FINS(r =0.249, P ＜ 0.01), 30minlNS (r =0.189, P ＜ 0.01) ,2hlNS (r =0.206, P ＜ 0.01), glycosylated hemoglobin (HbAlc, r=0.106,P =0.042), HOMA-IR(r =0.244,P ＜0.01), TG(r =0.350,P ＜0.01), ΔI30/ΔG30 (r =0.144, P ＜ 0.01), and negatively correlated with HDL-C level (r =-0.321, P ＜ 0.01).Multiple stepwise regression analysis showed that SUA (β =0.292, P ＜ 0.01) and HOMA-IR (β3 =29.821, P ＜ 0.01)were positively associated with ΔI30/ΔG30.Conclusion SUA level is closely related with the early-phase insulin secretion in NGR subjects.

OBJECTIVETo discuss the application and clinical effect of damage control concept in the treatment of severe limbs fractures combining with multiple trauma.

METHODSFrom July 2009 to July 2012, 30 patients with severe limbs fractures combining with multiple trauma were treated with the damage control concept, included 20 males and 10 females with an average age of (34.03 ± 12.81) years old ranging from 20 to 60 years old; the ISS averaged (35.00 ± 12.81) points (ranged from 26 to 54 points). And the control group also contained 30 patients with severe limbs fractures combining with multiple trauma treated by the traditional operation from June 2006 to June 2009, there were 23 males and 7 females with an average age of (34.23 ± 11.04) years old ranging from 18 to 65 years old. The ISS averaged (35.56 ± 11.04) points (ranged from 26 to 51 points). The age, gender, ISS, Gustilo classification, operation time, intraoperative blood loss, blood transfusion,postoperative complications and mortality rate were observed and compared.

RESULTSIn the damage control concept group,there were 28 cases surviving and 2 cases (6.7%) death; 6 cases of postoperative complication included 2 cases of adult respiratory distress syndrome, 1 case of multiple organ failure, 1 case of disseminated intravascular coagulation and 2 cases of wound infection. In the control group, there were 22 cases surviving and 8 cases death(26.7%); 13 cases of postoperative complication included 4 cases of adult respiratory distress syndrome,2 cases of multiple organ failure, 2 cases of disseminated intravascular coagulation and 3 cases of wound infection. There were no statistically significant differences between two groups in age, gender, ISS, Gustilo classfication and complication (P > 0.05), however there were statistically significant differences in mortality rate, operation time, blodd loss, blodd transfusion between two groups (P < 0.05).

CONCLUSIONDamage control concept is used to treat severe limbs fractures combining with multiple trauma which has the rapid and effective therapy, can improve survival rate and reduce complication.

Objective To systematically evaluate the safety of high dose atorvastatin (80 mg daily) in Chinese patients. Methods Randomized controlled trials (RCTs) investigating 80 mg/ d atorvastatin vs. low-dose atorvastatin or placebo or blank were electionically retrieved in date bases of EMbase, PubMed, the Cochrane Library, WanFang, CNKI and WeiPu. Meta-analysis was performed using RevMan 5. 2 and Stata 11. 0 software. Results A total of 20 RCTs involving 2282 cases were included. The results of meta-analysis showed no significant differences betweent the 80 mg/ d atorvastatin group and the control group in the incidence of gastrointestinal adverse events (RR 1. 53, 95% CI 0. 85-2. 76, P = 0. 16), hepatic adverse events (RR 1. 53, 95% CI 0. 99 - 2. 36, P = 0. 05), muscular adverse events (RR 1. 51, 95% CI 0. 92 -2. 49, P = 0. 10), serious hepatic injuries ( RR 2. 33,95% CI 0. 88 - 6. 20, P = 0. 09) and serious muscular myopathies (RR 1. 40, 95% CI 0. 46 - 4. 30, P = 0. 56). Subgroup analysis by type of cotrast media used and durations of taking 80 mg/ d atorvastatin showed there were higher risks of gastrointestinal adverse events in the 80 mg/ d group when compared to blank control ( RR 4. 22, 95% CI 1. 11 - 16. 04, P = 0. 03). Conclusions The current evidence shows that 80 mg / d atorvastatin may be relatively safe in terms of adverse events in gastrointestinal tract, liver and muscular system, and relatively has risk in causing severe liver injuries and myopathies. With limited quantity and quality from the RCTs available, more high quality RCTs are needed to verify the above conclusion.

Objective To analyze the adverse reactions of hysterosalpingography and prevention measures. Methods Totally 6 352 patients who underwent hysterosalpingography in our hospital between January 2006 and December 2013 were analyzed. Results Totally 836 cases had adverse reactions of different degrees including 312 cases of drug reactions and 626 cases of non?drug reactions. The adverse drug reactions were mainly hy?pogastralgia,laryngopharyngeal malaise,irritating cough,nausea,vomiting,shortness of breath,flush of the face,and pruritus. The non?drug reac?tions were mainly hypogastralgia,nausea,vomiting,pallor,speeding up of heart?beat,decreased blood pressure,dizziness,and blur version. Con?clusion Among patients who were negative for iodine anaphylactic test,there were still some who had adverse reactions of different degrees during HSG. Targeting at different conditions of reactions,corresponding prevention measures should be adopted to ensure the smooth progress of hysterosal?pingography.

Objective To analyze the risk factors of hospital acquired pneumonia (HAP) caused by nonfermentative bacteria in ICU.Methods Using binary logistic regression analysis,we reviewed the related risk factors of hospital acquired pneumonia caused by nonfermentative bacteria from January,2002 to May,2006 in ICU of our hospital.Results Univariate regression ana- lysis identified 22 variables associated with HAP,including age,diabetes mellitus,malignant tumor,chronic obstructive pul- monary disease (COPD),smoking,Glasgow Coma Scale (GCS) score,Acute Physiology and Chronic Healthy EvaluationⅡ(APACHEⅡ) score.Multivariate regression analysis confirmed 6 high risk factors:aspiration,COPD,use of antacids,seda- tive agents,mechanical ventilation and tracheal intubation or tracheostomy.Conclusions Aspiration,COPD,use of antacids, sedative agents,mechanical ventilation,tracheal intubation or tracheostomy are high risk factors associated with HAP.

OBJECTIVETo investigate the correlation of the deleted azoospermia (DAZ) gene copy related to gr/gr and b2/b3 deletions in the AZFc region with male spermatogenic impairment.

METHODSThis study included 121 infertile men with different de- grees of spermatogenic impairment and 95 healthy donors from the sperm bank. Using PCR, PCR-RFLP, and Y chromosome specific sequence tagged sites (STS) , we analyzed the association of DAZ gene copy deletions related to gr/gr and b2/b3 deletions in the AZFc region with spermatogenic impairment.

RESULTSThere were 15 cases of gr/gr deletion (12. 40% ) and 6 cases of b2/b3 deletion (4.96%) in the infertility group as compared with 13 cases of gr/gr deletion (13.68%) and 1 case of b2/b3 deletion (1.05%) in the control. Analysis of the DAZ-specific single nucleotide variant (SNV) loci revealed 11 gr/gr-DAZI/DAZ2 deletions (9.09%), 4 gr/gr-DAZ3/DAZ4 deletions (3.31%), and 6 b2/b3-DAZ1/DAZ2 deletions (4.96%) in the infertile men in comparison with 3 gr/ gr-DAZ1/DAZ2 deletions (3.16%), 10 gr/gr-DAZ3/DAZ4 deletions (10.53%), and 1 b2/b3- DAZ3/DAZ4 deletion (1.05%) in the control.

CONCLUSIONPartial deletions of gr/gr and b2/b3 exist in both healthy men and male patients with different degrees of spermatogenic impairment and cannot be considered as a risk factor for spermatogenesis impairment. However, deletions of different DAZ duplicons in gr/gr and b2/b3 deletions have different effects on spermatogenesis. DAZ1/DAZ2 instead of DAZ3/DAZ4 deletions might be associated with spermatogenesis impairment.

Aim: Clone and characterize of the 5′- flanking region of the nitrate reductase (NR) gene derived from Dunaliella salina(D. salina). Methods : The genomic DNA from D. salina was respectively digested with BamHI, EcoRI, HindIII, Pst I, Sal I and Xba I. A genomic walking cassette was ligated to the ends of the digested DNA fragments, and then genomic walking libraries comprising BL, EL, HL, PL, SL and XL were constsucted. The 5′- flanking region of the NR gene from genomic walking libraries of D. salina was amplified by LA-PCR. The DNA sequences were analyzed with the software - Promoter Predictions. Isolated 5′-flanking regions fused to the GUS gene were tested for transient expression in the alga. Results: A single specific PCR product of about 1200bp in length from the HL library was generated. Also, several conserved motifs, such as CAAT-box, GAGA-box were found, which are related to regulation of transcription, and the putative binding sites of transcriptional factors such as EBP, EFII, NF-E1 and LV. BLAST showed that the DNA sequences shared high homology with 5′-upstream region of the NR gene from Dunaliella viridis. The isolated 5′-flanking regions were able to strongly drive GUS reporter gene expression, suggesting that it contains the promoter elements necessary for the transcription of the NR gene. The expression pattern of the GUS gene and the NR gene were similar, both ware induced by nitrate and repressed by ammonium. Conclusion: The cloned 5′- flanking sequences of NR gene derived from D. salina might be a specific promoter with the ability to“switch on or off” an expression of the heterologous gene in transgenic D. salina.

In order to prepare the recombinant vasoactive intestinal peptide (VIP) using intein mediated rapid purification system,the cDNA encoding the recombinant VIP was designed and synthesized according to the preference of E.coli,and then was cloned into the expression vector PTWIN. The recombinant plasmid PTWIN-VIP was transformed into expression host E.coli strain ER2566.The fusion protein consisting of the recombinant VIP,intein and chitin binding domain was expressed and purified by chitin affinity chromatography. The target peptide was released from the fusion protein by changing the temperature and the pH of the cleavage buffer. The molecular weight of the recombinant VIP was determined by the mass spectrometry and the results was conformity with the theoretical value. The preliminary bioactivity assay indicated that the recombinant VIP decreased the serum resistin levels significantly in LPS-induced acute inflammation. The preparation and the characterization of anti-inflammatory effects of the recombinant VIP layed the foundation for its further application.
