Chinese Journal of Dermatology 1995;0(01):-
Objective To study the relationship between HLA-DRB1alleles and the systematic lupus erythematosus of the Zhuang Nationality in Guangxi Province.Methods Allele polymerase chain reaction-sequence specific primers(PCR-SSP)were used to study the HLA-DRB1allele genes in52patients with SLE and70healthy controls of the Zhuang Nationality in Guangxi Province.Results The allele frequencies of HLA-DRB1*1401and HLA-DRB1*16were significantly less in SLE patients than those of the controls(RR=0.28,? 2 =5.00,P=0.02and RR=0.39,? 2 =3.95,P=0.05).HLA-DRB1*08,DRB1*11and DRB1*13alleles were not found in these two groups.Conclusion Our data suggest that the HLA-DRB1*1401and HLA-DRB1*16might be protecting genes for SLE in Guangxi Zhuang nationality.No susceptible gene is found in our study.

Objective To evaluate the potential effect of HLF (Hawthorn leave flavonoids, w/w, 80% flavonoids) against thrombus formation, effect of HLF on hypoxia-treated human umbilical vein endothelial cell (HUVECs) was studied. Method The levels of cytotoxicity and NO upon HUVECs were studied by flow cytometry. Moreover, the level of calcium ion in HUVECs was examined through laser scanning confocal microscopy. Result Data from this study showed that HLF at concentrations of 5 μg/ml and 10 μg/ml decreased the cytotoxicity of hypoxia to HUVECs (P<0.05, P<0.01). The intracellular levels of NO and calcium ion were downregulated by HLF at concentrations of 5 μg/ml (P<0.01; P<0.01) and 10 μg/ml (vs control, P<0.01; P<0.01) too. Conclusion Results observed suggest that HLF protect HUVECs from hypoxia partly through its regulative effect on NO and calcium ion levels.

Objective To study the effect of anticholinesterase agents on acantholysis in pemphigus vulgaris (PV) by using a mouse model.Methods Fifty-five neonatal BALB/c mice were divided into four groups:model group injected subcutaneously with the sera of patients with PV (n =15),pyridostigmine bromide group (n =15) and neostigmine methylsulfate group (n =15) subcutaneously injected with pyridostignine bromide and neostigmine methylsulfate respectively,in addition to the sera of PV patients,control group subcutaneously injected with sodium chloride physiological solution (n =10).The effect of anticholinesterase agents on acantholysis in PV was evaluated in terms of clinical presentation,histopathological manifestations and direct immunofluorescence findings.Results The injection of sera from PV patients induced characteristic changes of PV in neonatal BALB/c mice in the model group.The degree of acantholysis in the model group was higher than that in the pyridostigmine bromide group (H =21.584,P < 0.001) and neostigmine methylsulfate group (H =20.641,P < 0.001).No changes were observed in the control group.Conclusion Anticholinesterase agents can reduce the degree of acantholysis in the mouse model of PV.

Through the comparative study on the psychiatric specialist training system between China, Japan and Korea, we have found that the number of psychiatric specialist training base in Japan and Korea is more than that of our country. Japan has a higher requirement of the practice training experiences for trainees before training and emphasizes how well mastering general psychiatry and understanding of society as trainees. However, the training bases in South Korean have main hos-pitals and sub main hospitals as well and trainees are stipulated to participate in a certain number of academic conferences and publish academic papers as their characteristics, which can provide a refer-ence for our country's adding more additional psychiatric specialist training bases and reasonable arrangements for trainee rotation in the future.

ObjectiveTo explore the role of activation and expression of absent in melanoma 2 (AIM2) in pathogenesis of hepatitis B virus (HBV) associated glomerulonephritis (HBV-GN).MethodsFifty-four patients with HBV-GN were recruited into the investigational group,and 25 patients with chronic glomerulonephritis (CGN) and 6 patients with chronic hepatitis B (CHB) were included as negative control group and positive control group,respectively.Immunohistochemistry was used to detect AIM2,Caspase-1 and interleukin (IL)-1β expressions in both kidney tissues from the investigational group and negative control group and liver tissues from positive control group.The differences between groups were compared by chi-square test,and the correlation analysis was conducted by Spearman correlation test.ResultsThe positive expression rates of AIM2 in 54 patients of HBV-GN group and 25 of CGN group were 81.4 % and 4.0%,respectively (x2 =38.746,P< 0.01).AIM2 was found to be expressed in all 6 CHB patients.In HBV-GN group,the expression of AIM2 was positively correlated with Caspase-1 (rs =0.444,P<0.01),and the expression of IL-1β was also positively correlated with Caspase-1 (rs =0.515,P<0.01 ).In HBV-GN group,the expression of AIM2 in patients with HBV DNA≥1 ×105 copy/mL was significantly higher than that in those with HBV DNA<1 × 105 copy/mL (x2 =6.097,P<0.05).ConclusionThe activation of AIM2 may play a role in the pathogenesis of HBV-GN through Caspase-1 activation and inflammatory factor IL-1β release.

Objective To evaluate the safety and effectiveness of immunosuppression regimens,postoperative complications,dead causes and risk factors of lung transplantation (LTx).Methods The immunosuppression regimens and clinical data of 100 patients with end-stage lung diseases receiving LTx in our hospital were retrospectively analyzed between Sept.2002 to Dec.2010.There were 72 patients subject to single LTx and 28 patients to bilateral LTx,amongst them 61 patients received LTx under circulation support,including 5 cases of cardopulmonary bypass (CPB) support and 56 cases of extracorporeal membrane oxygenation (ECMO) support.The immunosuppression regimens including Cyclosporin,mycophemolate Mofeil and corticosteroids were utilized in 53 recipients before the year of 2007,and Cyclosporin was switched to Tacrolimus in 47 patients after 2007.All the patients received Daclizumab or Basiliximab as immunosuppression induction regimens.Results The 1-,2-,3-and 5-year survival rate after LTx was 73.3%,61.6%,53.5% and 40.7% respectively.The mean survival time post-transplant in the patients who received Cyclosporin-based regimens and Tacrolimus-based regimens were (36.57 ± 3.44) months and (35.00 ± 2.33) months,repectively,with no significant differences (P>0.05).The main causes of mortality included primary graft dysfunction (PGD),acute rejection (AR),bronchiolitis obliterans (BOS) and sepsis.The incidence of AR and BOS in Tacrolimus group was significantly lower than that in Cyclosporin grou (P <0.05),but the incidence of diabetes mellitus was significantly higher in Tacrolimus group.Analysis of Spearman rank correlation revealed that there was a direct correlation between the incidence of AR and BOS (r =0.340,P<0.01).The use of circulation support,diagnosis of IPF,postoperative complications such as AR,BOS and infection were associated with decreased survival time postoperatively,in both univariate and multivariate proportional hazards regression models (P<0.05).Conclusion Cyclosporin-and Tacrolimus-based regimens were both effective immunosuppression strategies postoperatively,Consummate follow-up surveillance and prompt treatment of complications were the key points in prolongation of survival time and improving quality of life after LTx.
