OBJECTIVE:To discuss the clinical features and the general pattern of drug-induced hepatic lesions.METHO-DS:The clinical data of 170 drug-induced hepatic lesion cases collected from Jan.2002 to Apr.2006 in our hospital were analyzed retrospectively.RESULTS:Of the 170 cases,35.29% were induced by Chinese herbal medicines,13.53% by antipsychotic drugs,12.94% by anti-tuberculosis agent;51.18% were hepatocellular damage type,14.12% cholestatic damage type and 34.71% damage of mixed type damage.CONCLUSION:Hepatic lesions resemble viral hepatitis and were of no specificity in clinical features;various drugs can lead to hepatic lesions and to which clinic should attach great importance.

The morbidity and mortality of cardiovascular diseases(CVD)are still high in our country,they severely threaten peopleS health and quality of life.A dysregulated or reduced autophagy is associated with ischemic heart disease,cardiac hypertrophy,heart failure and arrhythmia.Autophagy is a key regulator in CVD development,and is essential for maintenance of heart function and improvement of prognosis.Thus,modulating autophagy represents an attractive future therapeutic target for treating cardiovascular disease.This article reviewed the research progression about effects of autophagy on ischemic heart disease,cardiac hypertrophy,heart failure and arrhythmia.

Objective To study the influence of different dosages of atorvastatin in acute coronary syndrome female patients on vascular endothelial growth factor(VEGF) and brain natriuretic peptide(BNP).Methods 60 female cases of ACS patients were divided into A and B group.30 patients in the A group were given atorvastatin 20mg per night,while the other 30 patients in the B group were taken 40mg per night.The patients were followed four weeks by evaluating serum VEGF and BNP concentration.Results After treatment for four weeks,the patients in the two groups showed significant reduction in VEGF and BNP,however,the therapeutic group showed significant difference between the two groups.Additionally,the B group further showed significant reduction in VEGF and BNP.Conclusion Using high-dose atorvastatin lowers VEGF and BNP significantly,which could reduce female cardiovascμlar events.

OBJECTIVE To give a general introduction to the infection in the hospital,and supervision to key departments in order to prevent nosocomial infection occurrence. METHODS A vertical analysis was made on the basis of the survey involving the following three periods: the first period covered the second half of the year 2000(from Jul to Dec 2000),the second period covered the second half of the year 2002(from Jul to Dec 2002),and the third period covered the second half of the year 2004(from Jul to Dec 2004). RESULTS The periodical supervision and the vertical analysis in the same period showed the following: the rates of the infected patients in the departments showing a tend to go on rising from 2000 to 2002,and showing a tend to decline from 2002 to 2004. CONCLUSIONS The control of using antibiotics must be emphasized and they should be applied in a scientific and reasonable way.The key points include the management of purchasing drugs,clinical indications and usages,supervise and news feedback,etc.All of these measures could prevent the occurrence of nosocomial infection effectively.

Objective To investigate the therapeutic effect of Danhong injection combined with metoprolol tartrate tablets on cardiac arrhythmia in climacteric women.Methods Retrospective a total of 115 patients with arrhythmia in The First People’s Hospital of Guiyang from May 2014 to May 2016 were divided into the western medicine treatment group and the traditional Chinese and western medicine treatment group.Western medicine treatment group were treated by metoprolol tartrate tablets, the traditional Chinese and western medicine treatment group were treated by Danhong injection combined with metoprolol tartrate tablets.The effect of two groups of patients after two months of treatment were observed,the heart rate variability,heart function index,sleep quality and the incidence of adverse reaction rate were compared between two groups of patients before and after treatment .Results After treatment,the effective rate of the traditional Chinese and western medicine treatment group was 98.33%, higher than the western medicine treatment group (P<0.05);the levels of SDNN,SDANN,RMSSD and PNN50 (%) were significantly higher in the the traditional Chinese and western medicine treatment group than those in the western medicine group (P<0.05);the levels of SV,LVPS and LVEF in the traditional Chinese and western medicine treatment group were higher than that in the western medicine treatment group ( P <0.05 );the sleep quality of the traditional Chinese and western medicine treatment group was significantly improved compared with the western medicine treatment group(P<0.05);the abdominal distension, nausea and vomiting,fatigue and cough incidence were no difference between the two groups.Conclusion Danhong injection combined with metoprolol tartrate tablets arrhythmia in menopausal women has a better therapeutic effect ,can obviously improve the patients with heart rate variability and cardiac function and adverse reactions occurred rate is low.

Objective:To investigate whether enamel matrix proteins (EMPs) has osteoinductive property. Methods: EMPs and propylene glycol alginate (PGA) in the size of 2 mm3 were placed into calf muscle of 8 SD rats on experiment side. PGA was placed on control side. The rats were sacrificed four weeks after operation. The calf samples were examined by histological observation.Result:Bone-like and/or cartilage-like tissues was not observed in all the operated calf muscles. Conclusion:EMPs are not osteoinductive.

Objective To determine the normal ranges of N-terminal pro-brain natriuretic peptide(NT-proBNP) in normal children and children with symptoms of heart failure(HF),and to study their clinical implications.Methods Concentrations of serum NT-proBNP were determined in 80 normal children and 70 children with clinical symptoms of HF.Venous blood was taken in each subject,and plasma NT-proBNP was determined by ELISA method.Eighty normal children included 40 boys and 40 girls.Their ages ranged from 1 to 16 years old.Seventy children with HF were divided into two groups.The first group(n=45,21 males,24 females) included children with symptoms of HF caused by dilated cardiomyopathy(DCM).Their ages ranged from 1 to 16 years,and they had a left ventricular ejection fraction(LVEF) of less than 50%.The second group(n=25,11 male,14 female) consisted of children with symptoms of HF due to ventricular septal defect(VSD).Their ages ranged from 1 to 16 years,and they had an LVEF of 51%-78%.The serum NT-pro BNP levels were determined by ELISA method and LVEF was measured by echocardiography and clinical symptom score of heart failure was defined by using Ross Score.Results Serum concentration of NT-proBNP was 223.05 fmol/mL in normal children from 1 to 16 years old.NT-proBNP levels did not show a significant age-related or sex-related differences.In children with HF,the plasma NT-proBNP levels were significantly elevated(mean:1353.3 fmol/mL) compared to normal children(t=8.964 P

Objective To evaluate the effect of sleep deprivation on cognitive function in the rats undergoing propofol anesthesia.Methods Sixty healthy male Sprague Dawley rats,aged 14-18 weeks,weighing 200-250 g,were randomly assigned into 3 groups (n=20 each) using a random number table:control group (group C),propofol anesthesia group (group P),and sleep deprivation + propofol anesthesia group (group SDP).Propofol was given as a bolus of 15 mg/kg followed by an infusion of 40 mg · kg-1 · h-1 for 2 h in group P.After the rats were subjected to rapid eye movement sleep deprivation for 24 h,the rats received propofol anesthesia in group SDP.Before sleep deprivation,after sleep deprivation,and at 1,3 and 7 days after anesthesia,Morris water maze test was used to assess the learning and memory function,and the escape latency and frequency of crossing the original platform were recorded.Ten rats randomly selected from each group at 1 and 7 days after anesthesia were sacrificed,and brains were removed to observe the morphology of nerve cells in the hippocampal CA1 region (by Nissl's staining) and to detect the expression of phosphorylated Tau at Thr231 (Tau-pThr231) in the hippocampal CA1 region (by immunohistochemisty).Results Compared with group C,the escape latency was significantly prolonged,the frequency of crossing the original platform was decreased,the expression of Tau-pThr231 in the hippocampal CA1 region was up-regulated at 1 day after anesthesia in P and SDP groups (P＜0.05),especially in group SDP (P＜0.05),and there was no significant difference between the groups at the other time points (P＞0.05).The pathological changes were aggravated at 1 day after anesthesia in group SDP compared with group P,and there was no significant difference at 3 and 7 days after anesthesia between group SDP and group P.Conclusion Sleep deprivation can aggravate the transient cognitive dysfunction after propofol anesthesia,and the mechanism is related to promotion of Tau phosphorylation in the rats.
