Objective Among the various components of metabolic syndrome(MS),this investigation attempt to find the most important one.Furthermore,to verify the feasibility of using waist circumference(WC)for assessing the diagnostic criteria for MS proposed by the CDS in 2004.Methods Among 163 cases recruited,80 patients met the criteria of MS and 83 cases were diagnosed as non-metabolic syndrome group(non-MS).Age,WC,body mass index(BMI),fasting plasma glucose,lipid profile,blood pressure were compared between patients of MS and non-MS.Logistic regression analysis and area under curve(AUC)of receiver-operating characteristic(ROC)were used to study the predictive value of WC.Results Patients with CDS-defined MS showed a significantly higher age,WC,SBP,DBP,fasting plasma glucose,triglycerides(TG),1/HDL-C when compared with non-MS group.After adjusting for age,the family history of diabetes and hypertension,smoke,multiple logistic regression analysis revealed WC was the most important predictive factor for MS group.ROC analysis showed that the AUC of WC was 0.92 in the males,the cut-off value is 89.5 cm,the sensitivity was 0.84,the specificity was 0.93;the AUC of WC was 0.93 in the females,the sensitivity was 0.97,the specificity was 0.81 when cut-off value is 80.8 cm.This investigation has shown that smoking was also a component of MS.The relative risk of MS in current smokers and sustained smoker was higher than that of abstinence(6.88 vs 1.00 and 3.96 vs 1.00).Conclusion Central obesity is the riskest indicator for the diagnostic criteria for MS proposed by the CDS,WC is verified to be the accuracy and satisfactory predictive indicators for MS.Smoking may be a novel component of MS.

The distribution and prevalence of low pathogenic avian influenza virus in major live poultry wholesale markets around the Dongting Lake region ,China were investigated in our study to propose prevention and control measures on low pathogenic avian flu in the area of live poultry wholesale market .The samples were injected to SPF chicken embryos by allanto-ic cavity ,and then the allantoic fluid were harvested and used for hemagglutination (HA) .If it was positive by HA ,subtypes of the virus would be determined by hemagglutination inhibition (HI) and RT-PCT .We isolated 627 low pathogenic avian in-fluenza viruses in major live poultry wholesale market around Dongting Lake region systematically in winter and spring during 2009-2011 ,and the total separation rate was 22 .2% .The duck swab separation rate of low pathogenic avian influenza was the highest ,which was 24 .6% ,and the following was chicken swab that reached 21 .5% ,and the goose swab separation rate was 11% .We isolated 6 HA subtypes including H3 ,H4 ,H6 ,H9 ,H10 ,and H11 in every live poultry wholesale market ,and the separation rate of H9 ,H6 and H4 subtypes was relatively high ,which could reach 11% ,6 .3% and 3 .4% ,respectively . Those results indicated that recessive infection of low pathogenic avian influenza virus was serious in live poultry wholesale mar-ket around the Dongting Lake area ,and it was a great threat to the occurrence of avian flu .

Objective:To explore the influences of times of venous thromboembolism (VTE) drug prophylaxis in formation of deep vein thrombosis (DVT) in patients with severe craniocerebral injury after surgical treatment.Methods:Ninety patients with severe craniocerebral injury, admitted to our hospital from February 2021 to December 2021, were chosen in our study; they were divided into early group ( n=47, less than 48 h from the time of admission) and late group ( n=43, more than 48 h from the time of admission) according to the times of initiation for VTE drug prophylaxis (low molecular weight heparin calcium injection [LMWH] 100 IU/Kg was injected subcutaneously once a d). One week after injection, the DVT formation in the lower limbs, intracranial rebleeding, gastrointestinal bleeding and death were compared in the two groups. Results:The times of initiation for drug prophylaxis in the early group and late group were (28.91±4.50) h and (71.56±8.89) h. The DVT formation in the early group was significantly lower than that in the late group (12.8% vs. 34.9%, P<0.05). There was no difference in the incidence of intracranial rebleeding, mortality or gastrointestinal bleeding between the two groups ( P>0.05). Conclusion:Early initiation of VTE drug prophylaxis can significantly reduce the incidence of DVT in patients with severe craniocerebral injury after surgical treatment, enjoying high safety.
