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 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 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 .

ITS2 sequence was used as a barcode to identify Viticis Fructus and its adulterants. The study collected 46 samples include Viticis Fructus and its adulterants. The sequences were obtained by extracting DNA, amplification, sequencing bi-direstionlly, and then assembling with CodonCode Aligner. To identify Viticis Fructus and its adulterants, the study used the methods of computing the genetic distances by Kimura 2-Parameter (K2P) model and constructing the Neighbor-joining (NJ) phylogenetic trees using MEGA5.0. The results showed that the maximum inter-specific K2P distance of Viticis Fructus was less than the minimum inter-specific K2P distance of Viticis Fructus and its adulterants and the NJ tree indicated that the Viticis Fructus and its adulterants could be distinguished clearly. Therefore, using ITS2 barcode can distinguished Viticis Fructus and its adulterants accurately.

Epidemiological surveys show that folic acid can prevent prostate cancer, but fortified folic acid may increase the risk of the malignancy. The physician data queries from the National Cancer Institute of the USA describe folate as protective against prostate cancer, whereas its synthetic analog, folic acid, is considered to increase prostate cancer risk when taken at levels easily achievable by eating fortified food or taking over-the-counter supplements. We review the current literature to examine the effects of folate and folic acid on prostate cancer, help interpret previous epidemiologic data, and provide a clarification regarding the apparently opposing roles of folate for patients with prostate cancer. A literature search was conducted in Medline to identify studies investigating the effect of nutrition and specifically folate and folic acid on prostate carcinogenesis and progression. In addition, the National Health and Nutrition Examination Survey database was analyzed for the trends in serum folate levels before and after mandatory fortification. Folate likely plays a dual role in prostate carcinogenesis. There remains some conflicting epidemiologic evidence regarding folate and prostate cancer risk. However, there is growing experimental evidence that higher circulating folate levels can contribute to prostate cancer progression. Further research is needed to clarify these complex relationships.

Basal rate verification is the process to find and verify the basal rate of continuous subcutaneous insulin infusion (CSⅡ) required for basal glucose metabolism.In the present study,five cases of brittle diabetes were treated by CSⅡ with Insulin Lispro.After doses were adjusted to reach steady blood glucose levels,basal rate verifying tests were carried out.The results showed that the overall level and stability of blood glucose were improved markedly after CSⅡ.Before and after the verification of the basal rate,there was no significant difference in CSⅡ total doses.Basal rates decreased from 50％ of total to 30％ (P＜0.05),and boluses increased to 70％ (P＜0.05).The basal rates during lunch and supper time were reduced by half (P＜0.05),the boluses of lunch and supper were increased 1.5 times (P＜0.05),and square waves were needed to control postprandial blood glucose.These results suggest that the CSⅡ could smoothly control blood glucose level in brittle diabetes without basal rate verification.However,the implementation of the verification could better determine the basal rates for basal glucose metabolism,and thus help to identify diet-related boluses.

This paper presents a case of post-pancreatitis diabetes mellitus with seriously damaged islet function. The blood glucose level was successfully controlled by continuous subcutaneous insulin infusion ( CSII )therapy both in short and long terms.
