OBJECTIVETo study the effect of eight specifications of Cervi Cornu Pantotrichum on the osteoporosis of ovariectomized rats and grade the eight different specifications of Cervi Cornu Pantotrichum.

METHODTotally 100 SD female rats were divided randomly into 10 groups, namely the normal group, the model group and eight Cervi Cornu Pantotrichum groups of different specifications. Their bilateral ovaries were excised to reproduce the osteoporosis model. Meanwhile, the rats were given the eight different specifications of Cervi Cornu Pantotrichum for consecutively 12 weeks. Subsequently, the effects of the different specifications of Cervi Cornu Pantotrichum on bone mineral density and serum biochemical indicators of rats were observed. A clustering analysis was made for the eight specifications of Cervi Cornu Pantotrichum, with the serum content of ALP, BMP-2 and BGP as influencing factors.

RESULTAfter 12 weeks, the eight different specifications of Cervi Cornu Pantotrichum could significantly improve ALP, BMP-2, BGP in serum and bone mineral density of ovariectomized rats. And the cluster analysis showed similar results to the quality classification of traditional commercial herbs Cervi Cornu Pantotrichum.

CONCLUSIONDifferent specifications of Cervi Cornu Pantotrichum can antagonize the osteoporosis of ovariectomized rats, and their effects are related to the quality of commercial herbs.

OBJECTIVE To sudy drug resistance related gene of carbopenem resistant Pseudomonas aeruginosa and type 1 integrating enzyme gene.METHODS With PCR method to detect and analyze carbopenem resistant P.aeruginosa pertinent metal ?-lactamase IMP,VIM,SPM,GIM genes and cell membrane protein oprD2 gene and six main drug resistance genes of type Ⅰ integrating enzyme gene and five others.RESULTS Fifty one strains of imipenem and meropenem resistant P.aeruginosa SPM,GIM metal enzyme genes were detected to be negative,16 strains of IMP and 5 strains of VIM type metal enzyme were all positive,14 strains of carbopenem resistant P.aeruginosa oprD2 gene were positive,other 37 strains of P.aeruginosa oprD2 gene were negative,7 strains produced metal enzyme and cell membrane protein oprD2 gene were deleted at the same time,49 strains with type Ⅰ integrating enzyme gene intⅠ1 were positive.CONCLUSIONS It is indicated the gene deletion of P.aeruginosa outer membrane protein OprD2 is important mechanism of carbopenem resistant P.aeruginosa,the second is metal enzyme,type Ⅰ integrating enzyme exists largely in P.aeruginosa.This hints the monitoring that drug resistance gene spreads and propagates in bacterium strain must be reinforced.

Objective To evaluate the outcomes of pregnancy of unknown location (PUL) with serial of serum β-human chorionic gonadotropin (β-hCG) and transvaginal sonography.Methods A retrospective study was performed to analyze the relationship between serial serum β-hCG and transvaginal sonography among 315 women who were diagnosed with nonvisible intrauterine pregnancy during Jan 2015 to Dec 2015.Results The pregnancy outcomes of 315 women included 254 intrauterine pregnancies,43 ectopic pregnancies,and 18 spontaneously resolving miscarriages or spontaneously resolving ectopic pregnancies.The serial serum β-hCG curve was classified as rising hCG levels,declining or plateauing hCG levels.Different pregnancy outcomes could exhibit as rising or declining hCG curves.Conclusions It is critical to perform two or more serial serum β-hCG examinations followed by transvaginal sonography to establish the correct diagnosis for PUL.

A summary will be made in this article concerning foreign seniors’ probation of Cardiology. These points as follows are vital to the successful teaching: making sufficient preparations before practice; analyzing the emphasis and difficulties, encouraging students to become the subject of class by making inquiry, doing physical examination by themselves and discussing the cases, paying great attention to the education of medical morality nurturance and correcting the students’ case records seriously.

At present, the level of diagnosis and treatment of early gastrointestinal cancer has a larger gap between China and developed countries. In recent years, the advent of new endoscopic imaging techniques has improved the detection rate of early gastrointestinal cancer. Along with this, endoscopic submucosal dissection(ESD) enables radical resection for early cancer. In this article, we discuss how to improve the level of endoscopic diagnosis and treatment of early gastrointestinal cancer.

Objective Artificial mineral water pills were made by loading many kinds of trace elements into the ceramic carrier.Pure water could be mineralized after dipping the pills into the water.To assess the possible hazardous effects on the human health induced by the pills,a series of hygienic and toxicological experiments on the pills were carried out.Methods Acute oral toxicity test,micronucleus test of mice bone marrow cells,sperm abnormality test in mice and Ames test were con-ducted.Contents of trace elements,heavy metals and radioactivity in the mineralized water were determined according to the examination methods in Standard Examination Methods for Drinking Water and Examination Methods for Drinking Natural Min-eral Water.Results The contents of trace elements,heavy metals and radioactivity in mineralized water met the requirements of GB5749-1985Sanitary Standard for Drinking Water and GB8537-1995Sanitary Standard for Drinking Natural Mineral Wa-ter.Mineral pills were classified as actually non-toxic and the results of micronucleus test of mice bone marrow cells,sperm ab-normality test in mice and Ames test were negative.Conclusion Mineralized drinking water treated by artificial mineral pills were safe.

Objective To explore the variation of serum galectin-3 and its correlation with ventricular remodeling in children with chronic cardiac failure (CHF). Methods Forty-ifve children with CHF were included and divided into cardiac function II group (n=10 ), III group (n=18 ), and IV group (n=17 ) according to the severity of CHF. The subjects were also divided into endocardial fibroelastosis (EFE) group (n=21 ) and dilated cardiomyopathy (DCM) group (n=24 ) according to primary disease. Thirty health children were included as control group. The level of serum galectin-3 was detected by ELISA. The level of serum NT-pro BNP was measured by radio immunoassay. The index of ventricular remodeling was detected by ultrasonic cardiogram. The correlation of the level of serum galectin-3 with ventricular remodeling and the level of serum NT-pro BNP were analyzed. Results In 45 children ( 19 males and 26 females) with CHF, the mean age was 3 . 42 ± 1 . 89 years. The levels of serum galectin-3 and NT-pro BNP were higher in cardiac function II group, III group, and IV group than those in control group (all P?0 . 05 ). Spearman rank correlation analysis showed that the level of serum galectin-3 was positively correlated with the left ventricular end diastolic diameter, the left ventricular mass, the left ventricular mass fraction, and the level of serum NT-pro BNP (all P?

Objective To investigate the clinical effect of ulinastatin in preventing pancreatitis after endoscopic retrograde cholangiopancre-atography (ERCP).Methods The Cochrane Library,PubMed,EMBASE,CNKI,VIP,and Wanfang Data were searched for randomized controlled trials (RCTs)on ulinastatin for the prevention of post -ERCP pancreatitis published from 1970 to June 2016.Two researchers se-lected RCTs,extracted data,and evaluated methodological quality independently,and RevMan 5.3 software was used for the meta -analy-sis.The chi -square test was used for the heterogeneity analysis of RCTs included,and the funnel plots were used to evaluate publication bi-as.Results A total of six RCTs with 923 patients were included in this analysis.Compared with the placebo,ulinastatin had significantly better effects in preventing post -ERCP pancreatitis (OR =0.26,95%CI:0.13 -0.53,P =0.000 2),hyperamylasemia (OR =0.47, 95%CI:0.33 -0.67,P <0.001),and abdominal pain (OR =0.56,95%CI:0.34 -0.91,P =0.020).Compared with gabexate,uli-nastatin had similar effects in preventing post -ERCP pancreatitis,hyperamylasemia,and abdominal pain (P =0.52,0.13,and 0.79);low -dose ulinastatin also had similar effects as gabexate in preventing post -ERCP pancreatitis and hyperamylasemia (P =0.49 and 0.25).The funnel plots based on the effect of ulinastatin in preventing post -ERCP pancreatitis were slightly asymmetric,which suggested the presence of publication bias.Conclusion Ulinastatin (≥15 ×104 U)can effectively prevent post -ERCP pancreatitis,hyperlipi-demia,and abdominal pain in the general population and it is recommended to start using this drug before surgery.
