Objective To evaluate the application of “expert-guided network tracking system” in training community general practitioner for hypertension management.Methods Total 855 general practitioners (GPs) from 20 community health service centers in Hangzhou,Jiaxing and Shaoxing of Zhejiang province were divided into two groups: 430 GPs from 10 community health centers received training for hypertension management using “ expert-guided networking tracking system” (intervention group) in December 2008 and 425 GPs from another 10 health centers received conventional training (control group).Questionnaire surveys about the knowledge and skill of hypertension management were conducted before and 3 y after training.Results The awareness rates of knowledge about hypertension prevention and control,non-drug therapy and drug therapy increased from 37.0% (159/430),45.6% (196/430),42.8% (184/430) to 66.8% (284/425),81.4% (346/425),77.6% (330/425),respectively and the accuracy of case analysis increased from 38.4% (490/1290) to 73.3% (946/1290) (P <0.01) after training in intervention group.Meanwhile the knowledge and case management abilities in control group were also improved after conventional training,but the degree was significantly lower than that in the intervention group.Conclusions “Expert-guided networking tracking system” can significantly improve the knowledge and skills for hypertension management in community general practitioners.

Objective To evaluate the information of head injury caused by the major earthquake of Wenehuan and the diagnostic value of muhi-slice spiral CT(MSCT). Methods A total of 1557 earthquake victims were hospitalized, of which head CT scan was performed in 292 eases, and abnormalities were found in 225 of them. The composition, type of injury and MSCT findings of head injury were retrospectively analyzed. Results CT abnormalities were found in 225 victims, including 66 cases of skull fracture,50 eases of cerebral contusion and laceration, 55 eases of intracranial hematoma, 16 cases of subaraehnoid hemorrhage, 16 eases of subdural collection of fluid,20 eases of foreign substance of scalp,and 2 eases of traumatic cerebral infarction. Operation was performed in 22 of them. Conclusion The incidence of head injury in earthquake was high, and most of them were not severe. The examination of MSCT was rapid, MPR and 3D images can clearly show the lesion of craniocerebral trauma. MSCT can provide more valuable information for clinical therapy in craniecerebral trauma caused by earthquake.

Twenty-four compounds in the fruits of Forsythia suspensa were isolated and purified by column chromatography and preparative TLC. On the basis of comprehensive spectroscopic methods including IR, ESI-MS/MS, 1D and 2D NMR, these compounds were identified as ten ceremides (1-10), six triterpenes (11-16), one steroids (17), three flavonoids (18-20), two C6-C2 alcohols (21-22) and two lignans (23-24). Compounds 1-10 were reported from F. suspense for the first time, among which 1, 2, 4 and 5 were new ones.

OBJECTIVEFactor VIII( FVIII) gene knockout mouse model was established for further study on the treatment of hemophilia A.
METHODSExons 16-19 of the mouse FVIII gene were knocked out by ET clone, ES homologous recombination and tetraploid embryo compensation technology. PCR, reverse transcriptase-PCR(RT-PCR) and immunohistochemistry were used to detect the transcription and translation pattern of FVIII. The phenotype of the knockout mice was analyzed by examining the activated partial thromboplastin time (APTT) and FVIII activity (FVIII:C).
RESULTSPCR, RT-PCR and immunohistochemistry confirmed that FVIII was deficient in the FVIII gene knockout mouse. The APTT results showed that FVIII-deficient mouse plasma had a prolonged clotting time compared to normal mouse plasma. The FVIII:C in heterozygous, hemizygous and homozygous mice was 80%, 8% and 10% of that in normal mice, respectively.
CONCLUSIONThe phenotype of the FVIII gene knockout mouse appears grossly similar to that of human with hemophilia A. Establishment of this model may promote the development of new technologies of treatment to hemophilia A.

Objective To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) in peripheral blood for the outcomes in patients with acute intracerebral hemorrhage.Methods Consecutive inpatients with intracerebral hemorrhage diagnosed with the head CT were entolled.The modified Rankin Scale (mRS) was used to evaluate the functional outcomes at 90 d,0-2 wvas defined as good outcome,3-6 were defined as poor outcome,and 6 was defined as death.Univariate analysis was used to compare the demographic characteristics,baseline data,imaging,and laboratory findings between the groups.Multivariate logistic regression analysis was used to determine the independent correlation between NLR and the outcomes,and receiver operating characteristics (ROC) analysis was performed to assess the predictive value of NLR for the outcomes.Results A total of 205 patients with acute intracerebral hemorrhage were enrolled in the study,107 (52.2%) had poor outcome and 57 (27.8%) died.There were significant differences in age (P=0.038),Glasgow Coma Scale (GCS) scores (P=0.001),National Institutes of Health Stroke Scale (NIHSS) scores (P =0.001),neutrophil count (P =0.005),lymphocyte count (P =0.002),NLR (P =0.001),fasting blood glucose (P =0.012),hypersensitivity C-reactive protein (P=0.002),hematoma volume (P =0.005),and proportion of bleeding into the ventricles (P =0.002) between the poor outcome group and the good outcome group.There were significant differences in age (P =0.002),previous stroke (P =0.018),GCS scores (P =0.001),NIHSS scores (P =0.001),neutrophil count (P=0.008),lymphocyte count (P=0.001),NLR (P=0.001),fasting blood glucose (P=0.016),hematoma volume (P=0.001),and proportion of bleeding into ventricle (P=0.002) between the death group and the survival group.Multivariate logistic regression analysis showed that NLR was an independent predictive factor for poor outcome (odds ratio [OR] 2.405,95% confidence interval [CI] 1.613-3.587;P=0.001) and death (OR 2.268,95% CI 1.532-3.358;P =0.001) after adjusting for confounders.The ROC curve analysis showed that NLR had a higher predictive value for poor outcome at 90 d (area under the ROC curve 0.703,95% CI 0.632-0.774;P < 0.001).When the cutoff value was 2.3,the sensitivity and specificity were 61.7% and 72.4%,respectively.NLR also had a predictive value for death within 90 d (area under the ROC curve 0.706,95% CI 0.629-0.786;P =0.003).When the cutoff value was 2.2,the sensitivity and specificity were 63.2% and 72.6%,respectively.Conclusion NLR may have certain predict value for outcomes in patients with acute intracerebral hemorrhage.

Objective To investigate the efficacy and safety of endovascular recanalization 6-24 h after onset in patients with acute basilar artery occlusion,and explore the related factors for their prognoses.Methods Clinical data of 37 patients with acute basilar artery occlusion,received endovascular recanalization in our hospital from January 2016 to July 2019,were retrospectively collected;23 patients were into group of onset-to-puncture time (OPT)>6 h (6-24 h),and 14 patients were into group of OPT ≤ 6 h (0-6 h).Statistical methods were used to compare the postoperative symptomatic intracranial hemorrhage rate,good prognosis rate (modified Rankin scale [mRS] scores ≤ 3) and mortality 3 months after onset between the two groups;clinical data between the subgroups with good and poor prognoses in patients of group of OPT>6 h were compared.Results The postoperative symptomatic intracranial hemorrhage rate,and good prognosis rate and mortality of patients from group of OPT>6 h were 30.4%,47.8% and 43.5%,respectively;and there were no statistically significant differences as compared with those in patients from group of OPT≤6 h (35.7%,35.7%,and 42.9%,P>0.05).Scores of scales based on preoperative CTA images (posterior circulation-Alberta stroke program early CT scale [pc-ASPECTS],scale of posterior circulation on CTA [pc-CTA],and scale of basilar artery on CTA [BATMAN]) showed significant differences between the good prognosis subgroup and poor prognosis subgroup in patients fiom group of OPT>6 h (P<0.05).Conclusion Endovascular recanalization 6-24 h after onset is effective in patients with acute basilar artery occlusion,and the safety does not obviously decrease;scores of pc-ASPECTS,pc-CTA and BATMAN may be related to the clinical prognoses.
