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 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.

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 investigate the clinical significance of neutrophil parameters Neut‐X and Neut‐Y in the diagnosis of blood stream infection(BSI) .Methods The data in106 patients with blood stream infection and 51 cases in the healthy control group were retrospectively analyzed .The results of WBC ,neutrophil percentage ,Neut‐X ,Neut‐Y and procaclitonin (PCT ) were compared .Results Neut‐X and Neut‐Y in the BSI group were 1 393 .5 ± 33 .4 and 416 .2 ± 30 .0 respectively ,which were signifi‐cantly higher than 1 371 .9 ± 32 .7 and 391 .7 ± 23 .7 in bacterial culture negative group and 1 347 .2 ± 26 .2 and 371 .9 ± 21 .5 in the healthy control group ,the differences were statistically significant (P<0 .05) .Neut‐X and Neut‐Y had good correlation with PCT . Neut‐X and Neut‐Y levels in the Gram‐negative bacterial group were higher than those in the Gram‐positive bacterial group .Conclu‐sion Neut‐X and Neut‐Y parameters in the patients with BSI are significantly increased and can be used as the assistant diagnosis parameters of blood stream infection .

Objective To assess the value of the dynamic enhanced MR (DE-MRI)morphological features in diagnosis of non lac-tation mastitis.Methods We retrospectively studied the breast DE-MRI image data of 1 5 patients with non lactation mastitis con-firmed by pathology were retrospectively studies and the lesion morphological features and distribution were analyzed.Results Amonge 1 5 patients with non lactation mastitis,6 cases were the plasma cell mastitis,5 cases were granulomatous mastitis,2 cases were abscess,and 2 cases were cyst associated with inflammation.The typical features of non lactation mastitis on DE-MRI were fast wash-in,centrifugal enhancement sign,blur boundaries between lesions and normal breast tissue,increasing unilateral vessel sign in diseased breast.Conclusion Breast DE-MRI can show typical morphological features of non lactation mastitis.When dynam-ic information is obtained inconveniently,these are helpful in diagnosing and differential diagnosing non lactation mastitis.

AIM: To investigate the effect of mfn2 on mitochondrial function in steatosis hepatocytes. METHODS: Plasmid pEGFP-mfn2 was transfected into hepatocyte strain L02 by Lipofectamine 2000 in vitro, then the steatosis model of hepatocytes was establish by oleic acid induction. RT-PCR was used to evaluate mRNA expression and Western blotting was use to detect the protein expression. ATP level was determined by firefly luciferase bioluminescent. ROS production was measured by fluorescence probe DCFH-DA. Chondrosome transmembrane potential of L02 was observed by labeling of JC-1 and FCM. RESULTS: The stable expression of ectogenesis mitofusin2 in L02 cells was confirmed by RT-PCR and Western blotting. In the model of oleic acids induced lipid formation, Mfn2 obviously inhibited the descent of chondrosome transmembrane potential and ATP level, and increased ROS production in L02 cells. CONCLUSION: Up-regulated expression of mfn2 attenuates mitochondria dysfunction caused by oleic acids induced lipid formation.
