Objective To explore the effects of early adminstering various doses of atorvastatin on serum sCD40L level and prognosis in patients with acute coronary syndrome (ACS). Methods One hundred and sixty-eight patients with ACS were randomly divided into three groups, which were administered atorvastatin at the dose of 10mg/d (low-dose group, n=56), 40mg/d (middle-dose group, n=55) and 80mg/d (high-dose group, n=57), respectively. Levels of serum sCD40L and lipid before and after treatment were measured. The major adverse cardiovascular events (MACE) were followed up for mean 7.6?3.2 months. Results The levels of serum sCD40L had no significant changes before and after treatment in low-dose group, but significantly reduced 52.4% and 52.2% in high-dose group and middle-dose group after treatment (P

Objective To discuss color Doppler uhrasonographic (CDU) grading of varicocele (VC) in predicting the changes of the fertility index (FI) after varicocelectomy.Methods One hundred and fifty-one patients with VC were diagnosed and graded by CDU.All patients were grouped by the regurgitant volume and the maximum diameter of pampiniform plexus veins(PPV).The relation between the regurgitant volume and the maximum diameter of PPV and the changes of the FI after varicocelectomy was analyzed.Results The pathological regurgitation could be detected when the PPV diameter > 1.5 mm.The positive correlation was observed between the regurgitant volume and the diameter of PPV (r = 0.89, P <0.01).The pre- and postoperative FIs were extremely significant difference in regurgitation grade Ⅱ and regurgitation grade Ⅲ (P < 0.01) but not significant difference in regurgitation grade Ⅰ (P>0.05).The pre- and postoperative FIs were no significant difference in the group with the PPV diameter ≤ 2.0 mm (P > 0.05), but statistically significant difference in the groups with the diameters 2.1-2.5 mm and 2.6-3.0 mm (0.01 < P <0.05).FIs in the group with the diameter > 3.0 mm exhibited extremely significant difference after varicocelectomy (P < 0.01).Conclusions CDU grading of VC could be used to predict the changes of seminal quality after varicocelectomy.Varicocelectomy isn't necessary to the patients with VC that the PPV diameter ≤ 2.0 mm or pathological regurgitation being detected only on Valsalva maneuver.

One of the causes of the high cost of pharmaceuticals and the major obstacles to rapidly assessing the bioavailability and risk of a chemical is the lack of experimental model systems. A new pre-treatment technology, in vitro bionic digestion was designed for metal analysis in Lianhua Qingwen capsule. The capsule was digested on 37 degrees C under the acidity of the stomach or intestine, and with the inorganic and organic compounds (including digestive enzymes) found in the stomach or intestine, and then the chyme was obtained. Being similar to the biomembrane between the gastrointestinal tract and blood vessels, monolayer liposome was used as biomembrane model Affinity-monolayer liposome metals (AMLMs) and water-soluble metals were used for metal speciation analysis in the capsule. Based on the concentration of AMLMs, the main absorption site of trace metals was proposed. The metal total contents or the concentration of AMLMs in the capsule were compared to the nutritional requirements, daily permissible dose and heavy metal total contents from the "import and export of medicinal plants and preparation of green industry state standards". The metal concentrations in the capsule were within the safety baseline levels for human consumption. After in vitro bionic digestion, most of trace metals were absorbed mainly in intestine. The concentration of As, Cd, Pb was 0.38, 0.07, 1.60 mg x kg(-1), respectively, far less than the permissible dose from the "import and export of medicinal plants and preparation of green industry state standards".

Objective The study analyse the multi-drug resistance and epidemiological investigation in Acinetobacter baumannii.Methodes Using,multi-drug resistance gene test,three-dimension test,membranes active efflux test studied multi-drug resistance and epidemiological investigation.The genetype were analyzed by Amplified Fragment Length Polymorphism(AFLP).The strains' homology were researched by multi-gene cluster analysis methods.Results Cluster analysis show that the result of drugsensitive test,multi-drug resistance gene test and AFLP are accordant.The study find at least 3 clones by multi-gene cluster analysis methods.AFLP show that all of the multi-drug-resistance of A.baumannii evolutes from a clone.Conclusions The study combined with clinical practice find that ICU in Ningbo No.2 Hospital now is the core of the arises,evolution,transmission of A.baumannii.Strengthening management of ICU is very important to pretect the prevalence of Acinetobacter baumannii in nosocomial infection.

OBJECTIVE To analyze the existence state of drug-resistant gene,integron and Tn21/Tn501 transposon and the relationship of Acinetobacter baumannii in Ningbo No.2 Hospital by genetic mark.METHODS Twenty seven strains of A.baumannii were clinically isolated.Drug-resistant gene,integron,and Tn21/Tn501 transposon were analyzed using polymerase chain reaction(PCR).The relationship was analyzed with cluster analysis methods.RESULTS The positive rates of blaTEM,blaOXA-23 cluster,blaADC,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sulⅠ,and intⅠ1 were 81.5%,44.4%,85.2%,85.2%,66.7%,81.5%,85.2%,and 85.2%,respectively.The others were negative.The result of multi-gene cluster analysis showed that the clone transmission existed.CONCLUSIONS The clone transmission of A.baumannii exists in Ningbo No.2 Hospital.The outbreak of A.baumannii may be possible because there are more than 3 clone transmission strains.

Objective To study the effects of new triple therapy with clarithromycin plus amoxicillin and omeperazole combined into 3 therapeutic therapies, and 3 therapeutic courses to treat children with helicobacter pyloric(Hp) infection.Methods Two hundred and four patients who were diagnosed by gastroscopy as Hp-related gastroentestinal diseases and divided into 3 groups,randomly.Group A was treated with amoxicillin 50 mg/(kg?d)+bismuth citrate 7-8 mg/(kg?d)+metronidzole 15-20 mg/(kg?d) for six weeks;group B took the same drugs but for two weeks;group C was treated with clarithromycin 15 mg/(kg?d)+omeperazole 0.8 mg/(kg?d)+amoxicillin 50 mg/(kg?d) for 2 weeks.Results The rates of eradicate of Hp:group A 73.4%,group B 75%,group C 92%.The differences between group B and group C were very significant.Conclusion Triple therapy is more effective, less duration,well tolerated, less resistant,with higher rate of eradication.

OBJECTIVE To analyze the relationship of Acinetobacter baumannii in Ningbo No.2 Hospital by pulsed field gel electrophoresis(PFGE) and amplified fragment length polymorphism(AFLP).METHODS The sensitivity of 13 kinds antibacterials were analyzed according to American National Committee for Clinical Labotatory 2004′s Standard.The genotypes were analyzed by PFGE and AFLP.The relationship was analyzed with cluster analysis methods.RESULTS Twenty seven strains of A.baumannii were divided into two groups by AFLP method or into four groups by PFGE method.Cluster analysis showed the concordance.CONCLUSIONS Amplified fragment length polymorphism has more clinical practice.

OBJECTIVE To compare the three methods on relatedness analysis of Acinetobacter baumannii strains in hospital infection.METHODS Twenty-seven A.baumannii strains caused hospital infection were analyzed by pulsed field gel electrophoresis(PFGE),amplified fragment length polymorphism(AFLP) and multiple gene cluster analysis.RESULTS PFGE analysis showed 19 strains isolated from clinic were with identical clone;AFLP analysis showed 19 strains isolated from clinic were with identical clone;but multiple gene cluster analysis showed 3 clones including 11 strains carried with 8 positive genes(TEM,OXA-23group,ADC,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1),6 strains with 7 positive genes(TEM,ADC,aac(3)-Ⅰ,aac(6′)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1) and 4 strains with 6 positive genes(TEM,ADC,aac(3)-Ⅰ,ant(3″)-Ⅰ,qacE△1-sul1 and intⅠ1).CONCLUSIONS The resolving ability of multiple gene cluster analysis is higher than that of PFGE and AFLP in relatedness analysis of A.baumannii strains from hospital infection.
