Clinical medical postgraduate education is an important part of higher education in China.We analyzed the current status,major problems existed,direction of the reform and the prospect in the training system.Unifying cultivation criterion,diversifying form of academic degree system,making selection standard strict for advisors and decreasing the proportion of research work for doctors were considered as the effective measures to address these issues.

Hemorrhoid refers to soft vein mass formed by varicosity of submucosal veins around the end of the rectum and subcutanceous veins of the anal canal. It is the most common anorectal disease. This article summarized the regular patterns, features and advantages of Professor Yu Hai-Bo's acupuncture-moxibustion therapy for hemorrhoids, in order to guide the acupuncture treatment for hemorrhoids.

ObjectiveTo evaluate the efficacy and safety of Sirolimus (SRL) in immunosuppression following liver transplantation. Methods SRL was applied in 21 patients totally.Indication for adoption was Tac-related nephrotoxicity (4/21), suspiciously Tac-related hepatoxicity (8/21), Tac overdose (3/21), renal insufficiency pre-operation (2/21), or cancer (4/21). Median follow-up was 25. 4 months. Results SRL provided an adequate prophylaxis against rejection in all study patients, with one case of acute rejection. Sirolimus was Withdrawn in 2 cases due to its sideeffect. Tat-induced hepatoxicity in 6 cases and nephrotoxicity in 3 cases were relieved significantly.Conclusions SRL given alone appears to be an effective primary immunosuppressant regimen fororthotopic liver transplantation patients. Early conversion contributes to significant improvement of Tac-related hepatoxicity and nephrotoxicity.

OBJECTIVETo observe the acupoint distribution and clinical efficacy of lumbar disc herniationi (LDH) with different sensitive types.

METHODSEighty patients with LDH were randomly divided into a heat-sensitive moxibustion group (group A), a heat-sensitive acupuncture group (group B), a force-sensitive acupuncture group (group C) and a force-sensitive moxibustion group (group D), 20 cases in each one. In the group A and the group B, moxibustion and acupuncture were applied at two or three heat-sensitive acupoints separately. In the group C and the group D,acupuncture and moxibustion were used at two or three force-sensitive acupoints respectively. The treatment was given once a day, totally 10 times. The distribution law of the heat-sensitive acupoints and the force-sensitive acupoints and the change of M-JOA before and after treatment were recorded in the four groups.

RESULTSThe frequent heat-sensitive acupoints areas of LDH were at Yaoyangguan (GV 3), Dachangshu (BL 25), Zhiyang(GV 9), Guanyuanshu(BL 26) and Weizhong(BL 40). The major force-sensitive acupoints areas were at Shenshu (BL 23), Dachangshu (BL 25), Tianshu (ST 25), Guilai (ST 29) and Weizhong (BL 40). After treatment, the heat-sensitive acupoints in the group A and the group B were all reduced than those before treatment and the force-sensitive acupoints in the group C and the group D were declined as well (P < 0.01, P < 0.05). The M-JOA scores were obviously lower than those before treatment in the four groups (all P < 0.01). The score in the group A was reduced more apparently than that in the group B (P < 0.05). The score in the group C was declined more markedly than that in the group D (P < 0.05).

CONCLUSIONThere are diverse acupoints for LDH patients due to different sensitive types. All forms of stimulation can change the functional state of acupoints. Moxibustion is more suitable for heat-sensitive acupoints and acupuncture is optimal for force-sensitive acupoints.

Objective:To investigate the effects of dendritic cells(DCs)in pathogenesis of aplastic anemia,especially its roles in T cell abnormal activation.Methods:Direct immunofluorescence assays and flow cytometry(FCM)were used to determined proportion and kinds of DCs in bone marrow sample of patients with AA.The DCs were got from standard method by culturing mononuclear cells isolated from peripheral blood of normal person in medium with recombinant human granulocyte macrophage colony stimulating factor(rhGM-CSF)and interleukin 4(IL-4)in vitro.The phenotype of DCs were determined by FCM.After pulsed with purified cord blood CD34+ cells and stimulated with recombinant human CD40 ligand(rhCD40L),the ability of those cultured CDs to activate and promote auto T lymphocytes to proliferation was tested.The changes of TCR V? gene repertorie of those T cells were also investigated by real time quantitative PCR(RQ-PCR).Results:The CD1a+CD11c+ and CD11c+CD83+ double positive cells increased in bone marrow of patients of AA,especially the proportion of CD11c+CD83+ cells increased significantly in those patients.After primed with CD34+ cells,DCs induced from peripheral monocytes could activate T lymphocytes and promote T cells to proliferation.The restricted usage of TCR V? genes was confirmed by RQ-PCR in those activated T cells by DC as those in AA patients.Conclusion:DCs,especially with phenotype of CD11c+CD83+,may have great impact on oligoclonal expansion of lymphocytes in patients AA,but the antigen which recognized by auto T cells and stimulated it to proliferation are still needed to further investigation.

Objective To evaluate the relationship between apoE gene polymorphisms and gallstone. Methods We included all the published studies on the association between apoE gene polymorphisms and gall-stone. A meta-analysis was employed to summarize all these studies, calculate the pooled OR and its 95% confidence interval (95% CI) , and test the overall effects. The Egger's publication bias analysis and sensitivity analysis were carried out to evaluate the reliability and stability of the meta-analysis. Results Eleven association studies between the apoE gene polymorphisms and gallstone fulfilled our inclusion criteria. There were 1248 patients with gallstones and 1660 controls. Remarkable heterogeneities were discovered in the allele ε4 and genotype E3/E4 of apoE between gallstone and control subjects in these studies (P<0. 05). Their ORs and 95%CIs were 1.32 (1.01, 1. 71), 1. 60 (1. 04, 2. 46), respectively (P<0. 05). The results of sensitivity analysis and publication bias analysis showed the reliability and stability of this meta-analysis. Conclusion apoE gene polymorphisms are associated with gallstone. Those with the alleleε4 or genotype E3 /E4 had a higher risk of suffering from gallstone.

Objective To investigate the effect of calcipotriol on melanin synthesis by human melanocytes and its possible action mechanism.Methods Primary melanocytes were cultured with various concentrations(10~(-5),10~(-6),10~(-7),10~(-8),10~(-9),10~(-10) mol/L)of calcipotriol for 24 or 48 hours.Subsequently,MTT assay,NaoH assay.Dopa-oxidase assay,Western blot and semiquantitative RT-PCR were used to measure the cell proliferation of,melanin synthesis by.tyrosinase activity,protein and mRNA expression levels in the melanocytes.respectively.Those untreated melanocytes served as the control.Results The calcipotriol between 10~(-9) and 10~(-5) mol/L had no significant effect on the proliferation of cultured melanocytes(P＞0.05).while that of 10~(-9) and 10~(-8) mol/L increased tyrosinase activity by 137%and 123%,and enhanced melanin synthesis by 40.63%and 18.75%,respectively,compamd with untreated melanocytes(both P＜0.05).Moreover,the tyrosinase protein level increased by 270.4%(P＜0.05)in melanocytes treated with calcipotriol at 10~(-9) mol/L for 24 hours.The strongest tyrosinase activity and melanin synthesis was observed in melanocytes treated with calcipotriol of 10~(-9) moI/L.Conclusions The proliferation of melanocytes is unaffected by calcipotriol at 10~(-9) to 10~(-5) mol/L,but it can elevate the expression of tyrosinase protein,enhance tyrosinase activity,and promote melanin synthesis in melanocytes.
