Objective The empirical validity of the National Medical Licensing Examination (NMLE) has rarely been studied. This is one of the first studies comparing NMLE and annual assess-ment scores. This study provided the criterion-related validity evidence for the NMLE. The NMLE can be used to test the abilities and skills of physicians. Method We evaluated the test 163 residents in 12 medical school-affiliated hospitals who had finished their first year of tralning and had taken the NMLE and an annual skills assessment. We used Pearson correlations to estimate the relationship be-tween NMLE scores and annual assessment scores. Results A total of 163 residents met inclusion requirements. Correlations between NMLE scores and annual assessment scores ranged from 0.300 to 0.843. Conclusions The criterion-related validity of NMLE was high, so it can be use to evaluate the residents clinical competence indeed.

Objective To explore the ABO blood group and Rh blood group system antigen distribution in Huainan area.Methods To investigate the Huainan area of 24 035 voluntary blood donors of the ABO and Rh blood group system phenotype and gene frequency distribution by the population genetics of the blood type.Results In the Huainan area population,the gene frequency of ABO blood type distribution was r ＞ P ＞ q,the distribution of phenotype was O ＞ A ＞ B ＞ AB,the distribution of RhD(-)frequency was 0.36％,and this result was consistent with the RhD(-)frequency of 0.2％～0.5％ of the Han population in the country.Conclusion ABO blood group and Rh blood group were two separate systems,control their distributed rule in the Huainan region was very important to the clinical use of blood,establishment of a repository of rare blood group of RhD(-),alleviation the lack of state hospital transfusion,raising the level of clinical treatment and to the reducing the incidence of immunological transfusion reactions.

Objective To understand the incidence of abnormal glucose metabolism during pregnancy and the maternal and neonatal outcomes after standard management.Methods A retrospective study of maternal and neonatal outcomes was conducted in 1490 pregnant women who were diagnosed and treated for abnormal glucose metabolism and delivered in the Department of Obstetrics and Gynecology of First Hospital of Peking University from Jan 1995 to Dec 2004 by reviewing the medical records.The selected cases consisted of 79 women with diabetes mellitus(DM group),777 with gestational diabetes mellitus(GDM group),including 355 cases of A1,316 with A2 and 106 cases unclassified,and 634 with gestational impaired glucose test(GIGT group).Maternal and fetal outcomes were analysed in comparison with the controls of 19 013 pregnant women with normal glucose metabolism who delivered during the same period.Results(1)The total incidence of gestational abnormal glucose metabolism was 7.3% and increased gradually from 1995 to 2004.The first stage,from Jan 1995 to Dec 1999,saw a slow increase in the incidence [4.3%(376/8739)];the second stage,from Jan 2000 to Dec 2001,showed a fast increasing trend.The average incidence was 10.8%(445/4133).The incidence in the third stage kept stable at 8.9% (678/7640)from Jan 2002 to Dec 2004.(2)The incidence of macrosomia,preeclampsia and preterm birth were 12.1%(180/1490),9.5%(141/1490)and 9.4%(140/1490),which were significantly higher than those women with normal glucose metabolism(P0.05).(3)The perinatal mortality rate(PMR)of abnormal glucose metabolism group was 1.19%(18/1513)which was significantly higher in the DM group (4.93%)than GDM(1.14%)and GIGT groups(0.78%,P

OBJECTIVE:To investigate synergistic effect of carbapenems combined with fosfomycin(FOS)on carbapenems-re-sistant Pseudomonas aeruginosa isolates from urinary tract infections in vitro. METHODS:The minimum inhibitory concentration was detected using agar double dilution method. The fractional inhibitory concentration index was determined by checkerboard meth-od. The effect of carbapenems combined with FOS on biofilm of P. aeruginosa isolates was determined using 96 crystal violet stain-ing. RESULTS:12 strains of carbapenem-resistant P. aeruginosa isolates were highly sensitive to FOS and amikacin,and were com-pletely resistant to imipenem and meropenem. The combination of imipenem with FOS could induce a synergistic effect on 4 strains (33.3%);meropenem combined with FOS could induce a synergistic effect on 5 strains(41.7%);no antagonistic effect of carbap-enems combined with FOS appeared. FOS combined with carbapenems could inhibit the biofilm of carbapenems-resistant P. aerugi-nosa(P<0.05 or P<0.01). CONCLUSIONS:The combination of carbapenems with FOS possesses in vitro synergistic antibacteri-al effect on part of carbapenems-resistant P. aeruginosa isolates,the mechanism of which may be associated with inhibiting the bio-film.

Objective To study the biofilm formation ability and related gene distribution of Staphylococcus (S .) aureus iso‐lated from urinary tract infections to provide the theoretical basis for the prevention and treatment of clinical infection .Methods The minimal inhibitory concentration was detected using the agar double dilution method .The bacterial adhesion ability was deter‐mined by flat colony counting method .The biofilm formation ability was analyzed by the 96‐well crystal violet staining method .The biofilm‐associated genes were detected by PCR amplification .Results Eleven clinical strains of S .aureus were high resistant to pen‐icillin and erythromycin ,whereas were all sensitive to vancomycin and nitrofurantoin .All the isolates had a strong ability of adhe‐sion ,but the biofilm formation ability was weak .Among them ,the icaAD and icaBC genes were amplified in 10 S .aureus isolates . Conclusion The adhesion ability and biofilm formation ability of S .aureus isolated from urinary tract infections have the strain differences ,and ica is an important gene of S .aureus biofilm formation .

Objective To study the protective action of Semen Ziziphi Spiosaeand on acute myocardial ischemia and its effecte on infarcted area. Methods Left anterior descending(LAD) of coronary artery was ligated to cause the big rat's acute myocardial ischemia, and electrocardiogram (ECG) was used to appraise the effect of sour jujube kernel total soap on the myocardial infarcted area. Results Compared with control group, the experimental group treated with sour jujube kernel total soap glucosidal showed significantly smaller infarcted area; and ECG showed the heart rhythm, S-T piece and T wave value were significantly decreased in the experimental group. Conclusion Sour jujube kernel total soap glucosidal can reduce the myocardial infarcted area caused by ligature of LAD, so as to protect the cardiac muscle.

This study is to investigate the effect of hydroxyethylpuerarin on the expression of tumor necrosis factor-alpha (TNF-α) and activity of nuclear factor kappa B (NF-κB) after middle cerebral artery occlusion (MCAO) in rats. Rats were subjected to cerebral ischemia-reperfusion injury induced by MCAO. Hydroxyethylpuerarin (10, 20, 40 mg·kg-1, iv) was administered just 30 min before occlusion and immediately after reperfusion. After a 24 h reperfusion following 2 h of MCAO, the number of viable neurons in hippocampal CA1 region was counted by hematoxylin and eosin (HE) staining. TNF-α protein and its mRNA expression were examined with radioimmunoassay (RIA) and reverse transcriptase-polymerase chain reaction (RT-PCR) respectively. NF-κB activity was observed by electrophoretic mobility shift assay (EMSA), and inhibition of NF-κB α (IκBα) protein expression was evaluated by Western blotting analysis. Animals treated with hydroxyethylpuerarin had a significant increase in neuronal survival in comparison with vehicle-treated group. Hydroxyethylpuerarin significantly reduced the protein and mRNA expression of TNF-α following 2 h of ischemia with 24 h of reperfusion. NF-κB DNA binding activity and the degradation of IκBα in the cytoplasm also decreased by hydroxyethylpuerarin treatment. The protective effects of hydroxyethylpuerarin against ischemia-reperfusion injury may be mediated by decreasing the expression of TNF-α and the activity of NF-κB in rats.
