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.

We detected their carotid and femoral arteries using two dimensional and PW Doppler ultrasonography. The lesions degree were assessed according to U B 6 classification. Results: Higher incidence and more serious degree of arteries lesions occurred in diabetes mellitus than those in control group ( P 40 years old than in group ≤40 years old in diabetes mellitus ( P

BACKGROUND:Isoflurane cannot only induce a wide range of large neuronal apoptosis, but also inhibit hippocampal neurogenesis in neonatal rats, thereby resulting in hippocampus-dependent learning and memory defects.
OBJECTIVE:To investigate the isoflurane effect on proliferation and differentiation of the hippocampal neural stem cels.
METHODS:Twenty-six Sprague-Dawley rats were randomly divided into air group and isoflurane group (n=13 per group). Rats in the isoflurane group were subjected to 2.5% isoflurane inhalation for 3 minutes folowed by 1.5% isoflurane inhalation for 4 hours. Rats in the air group only breathed in air. After the intervention, blood glucose and arterial blood gas changes were detected in the two groups. Additionaly, rats in the two groups were given intraperitoneal injection of 5-bromodeoxyuridine before and after intervention. At 24 hours after the last injection of 5-bromodeoxyuridine, brain tissues were taken to make frozen sections for immunofluorescence staining.
RESULTS AND CONCLUSION:There were no significant difference in pH, PaO2, PaCO2, HCO3, BE and SaO2 levels between the two groups (P> 0.05). Compared with the air group, the number of BrdU+ cels was significantly less in the isoflurane group (P < 0.05), while the number of NeuroD+/BrdU+ cels was significantly higher in the isoflurane group (P < 0.05). The incidence of adverse reactions was 23% in the isoflurane group, which was significantly higher than that in the air group (7.7%;P < 0.05). These findings indicate that isoflurane can inhibit the proliferation of neural stem cels in the hippocampal dentate gyrus, and promote their differentiation into neurons.

Objective:It has been found that serum CXCL16 concentration in rheumatoid arthritis (RA) patients are significantly higher than those in osteoarthritis (OA) and normal subjects, and are positively correlated with disease activity and bone erosion.However, how is CXCL16 involved in the pathogenesis of RA is unclear.To evaluate the expression of CXCL16 and its receptor CXCR6 in fibroblast-like synoviocytes (FLS) of rheumatoid arthritis (RA) patients, and to explore the role of CXCL16 in the proliferation of RA-FLS.Methods: FLS were isolated from knee synovial tissues obtained from 8 patients of RA, 7 osteoarthritis (OA) and 3 normal controls.The diagnosis of RA was in line with the 1987 American Rheumatology Association (ACR) RA classification criteria, osteoarthritis met the 1996 ACR revised knee osteoarthritis classification criteria.Control synovium were obtained from trauma caused knee joint injury in healthy individuals who required surgery.Human knee FLS were cultured by tissue explants adherent method.FLS between passages 3 and 5 were used in the experiment.Expression of CXCL16 and its receptor CXCR6 were performed in Western blot analysis.FLS proliferation follo-wing stimulation with TNF-α and different concentrations of CXCL16 was examined by cell counting kit-8 (CCK-8).Expression of phosphorylated AKT (pAKT) in RA-FLS stimulated by CXCL16 was quantified by Western blot.Different concentrations of recombinant human CXCL16 were added to the culture medium of RA-FLS.After 48 h culture, supernantants were collected, and TNF-α, IL-6, RANKL and MMP3 in culture supernatants of RA-FLS were determined by enzyme-linked immunosorbent assays (ELISA) operated following the kit instructions.Results: Expression of CXCL16 and CXCR6 in RA-FLS was significantly higher than that of OA and controls (P<0.05), but no significant difference was found between OA-FLS and control FLS.Proliferation of RA-FLS was markedly up-regulated after stimulation of CXCL16 (P <0.05).In the case of the CXCL16 stimulated OA-FLS and control FLS, the FLS proliferation remained basically unchanged.Expression of phosphorylated AKT in RA-FLS increased remarkably in condition of CXCL16 (50,100, 200 μg/L) stimulation.The levels of IL-6 and RANKL in culture supernatants of RA-FLS were obviously increased under CXCL16 (200 μg/L) stimulation, while TNF-α and MMP-3 levels in the culture supernatants remained unchanged after CXCL16 (200 μg/L) stimulation.Conclusion: This study shows that the expression of CXCL16 and its receptor was highly elevated in RA-FLS.Recombinant CXCL16 promoted RA-FLS proliferation and activation in vitro.All these indicate that CXCL16 play an important role in the pathogenesis of RA, anti-CXCL16 treatment may help to relieve inflammation and bone damage of RA patients.However, due to the limitations of this study, the role of CXCL16 and its receptors in RA-FLS remains to be elucidated by further research.

Objective To study clinical efficacy of leuprorelin acetate in treatment of uterine adenomyosis with infertility.Methods From January 1,2011 to March 31,2012,166 cycles in 166 infertile patients combined with uterine adenomyosis undergoing in vitro fertilization embryo transplant (IVF-ET) with long protocol ovum induction by leuprorelin acetate in centre of medical reproduction,ningbo women and children's hospital were studied retrospectively.In the mean time,200 cycles in 200 infertile patients with tubal factors were enrolled as control group.The volume of uterus and outcome of IVF-ET were compared and studied between two groups.Results (1) Volume of uterus:in adenomyosis group,after 2-6 cycles of injecting leuprorelin acetate (3.75 mg/28 days),the mean uterine volume was shrinked from (180 ±73) cm3 to (86 ± 67) cm3 (P ＜ 0.05).(2) Outcome of IVF-ET:the rate of embryo implantation was 39.1％ in adenomyosis group and 35.8％ in control group.The rate of clinical pregnancy was 54.2％ in adenomyosis group and 53.7％ in control group.The rate of abortion was 4.7％ in adenomyosis group and 4.2％ in control group.They all did not show statistical differences (P ＞0.05).(3) In adenomyosis group,the rate of fertilization,two pronuclear (2PN) and superior embryo were 67.2％ (319/475),60.8％(289/475) and 52.9％ (162/306) in patients with failed pregnancy and 74.2％ (423/570),67.7％(386/570) and 62.1％ (256/412) in patients with successful pregnancy after IVF-ET,which reached significant difference (P ＜ 0.05).Conclusion Leuprorelin acetate could improve volume of uterine adenomyosis and outcome of pregnancy in patients undergoing IVF-ET.

Objective To explore human cytomegalovirus UL97 mutations related to ganciclovir resistance in hematopoietic stem cell transplant (HSCT) recipients.Methods A total of 43 patients,including 24 males and 19 females,with an average age of 21 years old,who had HCMV DNAemia for more than two weeks after HSCT between 2008 and 2010 in Peking University People's Hospital,were included in this prospective study.UL97 GCV resistance mutations were investigated in 49 plasma specimens collected from those patients.GCV resistance mutations such as UL97 M460V/I,H520Q,A591V,A594V,L595S/F,and C603W,were analyzed by modified PCR-RFLP methods.UL97 mutations related to GCV resistance were assayed by the method of PCR-direct sequencing (PCR-DS).An amplified refractory mutation system real-time PCR (ARMS RT-PCR) was developed for the detection of UL97 A594V mutation.Results Eight known UL97 ganciclovir resistance mutations were not detected by PCR-RFLP and PCR-DS.Four new UL97 mutations like UL97 R494P,T502A,N558D,and G561S,were detected by PCR-DS.The ARMS RT-PCR for detecting of UL97 A594V was established successfully.The lower limit of detection of the method was at least 7.5 × 102 copies/ml combined with the use of nucleic acid extraction reagent.UL97 A594V resistance mutation was identified by the method of ARMS RT-PCR in two HSCT recipients.The rate of UL97 A594V mutation was 4.7％ (2/43) in HSCT recipients.Conclusion The ARMS RT-PCR assay represented a sensitive method for the identification of UL97 A594V mutation.
