Objective To explore cardiovascular risk factors in patients of hypertension (HTN) complicated with non-alcoholic fatty liver but normal aminotransferase. Methods Forty-four cases (control group) of uncomplicated hypertension and 56 cases (study group) of hypertension complicated with nonalcoholic fatty liver but normal aminotransferase were screened from those who visited physical examination center of the hospital for regular checks-up during October 2009 to June 2010. Blood pressure ( BP), body mass index ( BMI), fasting plasma glucose (FPG), total serum cholesterol (TC) , triglyceride (TG), highdensity lipoprotein-cholesterol ( HDL-C ), low-density lipoprotein-cholesterol ( LDL-C ), gammaglutamyltransferase ( GGT ), uric acid ( UA ) , highly-sensitive C-reactive protein ( hs-CRP) and homocysteine (Hey) of the two groups were compared. Results Comparing with the control group, the study group had higher diastolic blood pressure ( DBP) (t = 1898. 5, P < 0. 05) , BMI (t = - 5. 036, P < 0.01), FPG (t= -2.026, P<0.05), TG (t = 1923. 5, P<0.05), GGT (t = 1789, P <0.01), UA 0 = 1715, P<0.01), hs-CRP (t = 1832.5, P < 0.01) and lower level of HDL-C (t =2357.0, P< 0. 01). Serum activity of GGT correlated positively with BMI (rs = 0. 349, P = 0. 000), TG ( rs = 0.413,P =0.000), UA (rs =0.446, P= 0.000) and hs-CRP (rs =0.350, P = 0.000), respectively.Conclusions When patients of hypertension complicated with non-alcoholic fatty liver but normal aminotransferase, their cardiovascular risk factors clustered further, with serum activity of GGT obviously increased which correlated positively with various risk factors, indicating increase in cardiovascular risks.

Objective To explore the feature and the optimal treatment of kidney stones in children associ-ated with infant formula which had been aduherated with melamine.Method Total of 47 cases of urinary stone and 31 cases of acute renal failure caused by urinary multiple obstruction in children associated with infant formula which had been adulterated with mlelamine in Beijing Children's Hospital University of Medical Science,form Jan-uary to November,2008 were retrospectively analyzed.Results Infant formula which had been adultemted with melamine may lead to kindey stones in 15 days.The mean age was 11-month and the ratio of male to female was 2.6:1.The kindey stones were usually multiple and mostly located either in the ureteropelvic junction or all through the ureter.In the view of the renal function resuming duration,there was no statistic difference among the acute renal failure group,operation group and the conservative group(P=0.683～0.846).In children with uri-nary obstruction and acute renal failure,hemedialysis or peritoneal dialysis was performed.83.9%were relieved by posting catheter through panedoseope and blood purification.100% of the patients resumed normal renal func-tion.81.3% of the patients without acute renal failure had recovered after conservative therapies such as infusion.Conclusions The patients associated with infant formula which had been adulterated with melamine were Usually little infants.Male were more vulnerable than female.Most of them had recovered smoothly and the renal function resumed normal after effcient therapies.

Objective To investigate the effect of the down regulation of matriptase expression on invasion of human pancreatic cancers cells SW1990.Methods Small interfering RNA targeting at matriptase (Ma-siRNA) was transfected into human pancreatic cancers SW1990 cells,and nonsense siRNA (NC-siRNA) group was used as control.Real time PCR assay and Western blot were used to detect the expression of matriptase mRNA and protein.Transwell assay was used to examine the invasion ability of cancer cells.The enzymatic activity of matriptase and MMP-9 was determined by gelatin zymography assay.Results The expression level of matriptase mRNA in NC-siRNA group,12.5,25,50 nmol/L Ma-siRNA group were 1.000,0.417 ± 0.006,0.233 ± 0.068,0.221 ± 0.092;and the protein expression of matriptase were 0.736 ± 0.066,0.498 ± 0.036,0.341 ± 0.118,0.239 ± 0.050,respectively.The matriptase mRNA and protein expression in Ma-siRNA groups was significantly lower than those in NC-siRNA group,and the difference between the two groups was statistically significant (P ＜ 0.05).The enzymatic activity of matriptase were 1.501 ±0.165,1.211 ±0.265,0.645 ±0.165,0.620 ±0.003,and the enzymatic activity of MMP-9 were 0.929 ± 0.260,0.484 ± 0.364,0.352 ± 0.113,0.346 ± 0.121,and the enzymatic activity of matriptase and MMP-9 in 25,50 nmol/L Ma-siRNA groups was significantly lower than that in NC-siRNA group,and the difference was statistically significant (P ＜ 0.05 or ＜ 0.01).The number of transmembrane cell was (256 ± 1)/per 200 power field,and it was (109 ± 3)/per 200 power field in 25 nmol/L Ma-siRNA group,and the invasion ability of the cells in 25 nmol/L Ma-siRNA group was decreased by (57.4 ± 5.4) ％ when compared with that of control group.Conclusions Down-regulation of matriptase inhibits invasion ability of pancreatic cancer SW1990 cells,and this result may be due to the down regulated enzymatic activity of matriptase and MMP-9.

OBJECTIVE:To provide reference for rational use of antipsychotic drugs in schizophrenia patients. METHODS:The general information and antipsychotic treatment information,which were extracted from the database of prior drug investigation in Mental Health Center of Hebei Province in 2002,2006 and investigation data in 2012 of 5014 schizophrenia patients,were ana-lyzed. RESULTS:Over time,the frequency of the first generation antipsychotic drugs decreased(P<0.05),while that of the sec-ond generation antipsychotic drugs increased (P<0.01). The frequency of long-acting antipsychotic drugs were generally low among outpatients and inpatients in 2002,2006,2012,with statistical significance(P<0.01). There were no significant difference in the proportion of outpatients receiving antipsychotic drugs combination treatment and monotherapy (P>0.05). Over time,the proportion of inpatients receiving monotherapy decreased,while that of inpatients receiving combination treatment increased (χ2=18.682,P<0.01). CONCLUSIONS:The second generation antipsychotic drugs have gradually replaced the first generation antipsy-chotic drugs,and have became the leading drugs in the treatment of schizophrenia in Hebei province. The proportion of inpatients receiving combination treatment has increased,which is different from the domestic and foreign prevention and treatment guide-lines.

Objective: To investigate the dynamic electrocardiogram (ECG) changes of head-up tilt test in patients with suspected vasovagal syncope. Methods: A total of 502 outpatients of our hospital with suspicious vasovagal syncope from 2015-08 to 2016-12 were enrolled. All patients received head-up tilt test with synchronization of 12 lead ECG. Based on head-up tilt test result, the patients were divided into 2 groups: Positive group,n=244 and Negative group,n=258. The P wave duration, corrective QT (QTc) duration and P wave axis in ECG were compared between 2 groups. Results: Compared with Negative group, Positive group had the longer P wave duration (95.65±38.50) ms vs (88.61±17.09) ms,P<0.05; P wave axis was right shifted before syncope (69.87±18.18)° vs (66.82±16.51)° , while left shifted during syncope (62.87±25.39)° vs (68.47±15.30)° and after syncope (56.87±22.45)° vs (68.49±16.35)°, allP<0.05; the shorter QTc duration before syncope (418.69±92.35) ms vs (435.76±59.29) ms,P<0.05. Conclusion: The patients with vasovagal syncope had some speciifc ECG features during head-up tilt test including P wave duration, P wave axis and QTc duration, those may play certain forewarning function for vasovagal syncope onset.

Objective To evaluate the comprehensive medical goal appraisal system on hand hygiene compliance rate of health care workers(HCWs).Methods Comprehensive medical goal appraisal system was adopted to inter-vene hand hygiene compliance rate of HCWs in a comprehensive hospital ,hand hygiene compliance rates of HCWs and consumption of instant hand sanitizer per bed-day before (December 2012)and after intervention (January 2013-June 2014)were compared.Results Hand hygiene compliance rate after intervention was higher than before interven-tion (85.17% [18 208/21 379]vs 39.92%[853/2 137]),hand hygiene compliance rate enhanced by 113.35%(χ2 =2 590. 81,P <0.001).Hand hygiene compliance rates of HCWs of different departments,different occupations and different hand hygiene moments were all higher than before intervention (all P <0.001);after intervention ,hand hygiene compliance rate revealed a increased tendency,and has maintained high since October 2013 (>90%),consumption of instant hand sanitizer before and after intervention was 7.24 mL/bed-day(4 200 L/579 841 bed-day)and 10.54 mL/bed-day(9 323.5L/884 489 bed-day)respectively,the consumption after intervention increased by 45.58% compared with that before intervention. Conclusion Comprehensive medical goal appraisal can effectively enhance hand hygiene compliance rate ,and maintains at a high level;the measure can affect hand hygiene behavior of HCWs by hawthorne effect,and is an effective and long-term measure to improve hand hygiene compliance of HCWs.
