Objective To analyze the relationship between clinical and pathological features in children with Henoche-Sch?nelin purpura nephritis (HSPN). Methods Clinical and pathological data of 89 children with HSPN from April 2009 to April 2013 in our hospital were retrospectively analyzed. Results A majority of patients (94.83%) suffered nephritis within two month after purpura. Clinically, hematuria and proteinuria (41.6%), nephrotic syndrome (27.0%), and isolated protein-uria (21.3%) are the most common type in children with HSPN. The majority of pathological changes of these three types HSPN are gradeⅢ, which accounts for 67.6%, 70.8%, and 73.7%, respectively. The clinical manifestations are closely associated with pathologic classiifcation (H=26.88, P=0.000). IgA plus IgM deposit was the most common type (40.45%) in histological and immunopathologic changes.There was no statistical difference between the pathologic classification and immunopathologic types. Gastrointestinal bleeding was associated with pathologic classiifcation. Conclusions The pathological changes of HPSN patients are mainly of gradesⅡandⅢ, and the clinical manifestations, gastrointestinal bleeding in particular, are closely associated with pathological classiifcation.

Objective To investigate the expression of elongation of very long-chain fatty acids family member 6 (ELOVL6) in high-grade serous ovarian carcinoma (HSOC), and explore the correlation between its expression and clinical prognosis in these patients. Methods The expression of ELOVL6 at mRNA and protein levels were respectively detected by reverse transcription (RT)-PCR and immune histochemistry method in 12 cases with normal ovarian tissues and 172 cases with HSOC from primary tumor site, forty of which had paired peritoneal metastatic tissues. Results (1) The results tested by RT-PCR showed that ELOVL6 expression in normal ovarian tissue was 4.8±1.1, while 1.2±0.7 in primary tumors and 1.8 ± 0.9 peritoneal metastatic sites in HSOC. Compared with normal ovarian tissue, the level of ELOVL6 mRNA was significantly lower in HSOC (P<0.05). There was no significant difference between primary and peritoneal metastatic sites in HSOC (P=0.610). It was shown that ELOVL6 protein localized in cytoplasm of ovarian cancer cell by immunostaining assay. (2) ELOVL6 expression was observed in all normal ovarian tissue, 70.2%of G1-G2 and 48.8%of G3 HSOC (P<0.05). ELOVL6 expression in drug-resistant group were significantly lower than that in non-resistant group (39.1% vs 65.0%, P<0.01). The median disease-free survival was 41 months in the ELOVL6-positive group and 39 months in ELOVL6-negative group (P>0.05). The total median survival was 52 months in ELOVL6-positive group and 44 months in ELOVL6-negative group (P>0.05). Conclusion Low expression of ELOVL6 may correlate with the poor differentiation and drug resistance in HSOC.

Objectives To investigate the clinical effect of hemoperfusion in severe juvenile dermatomyositis. Meth-ods Two patients with severe juvenile dermatomyositis, who accepted hemoperfusion treatment, were retrospectively analyzed. Results In these 2 patients, the hemoperfusion process were smooth. The muscle pain was reduced and the muscle enzymes were decreased. After hemoperfusion, one patient refused to continue treatment and the disease recurrent. The other patient con-tinued to accept the immunosuppressive therapy and eventually improved. Conclusions For juvenile dermatomyositis, hemo-perfusion was a safe and effective auxiliary treatment. It could be applied when the general treatment was invalid.

Objective:To investigate the role and mechanism of retinal Sigma-1 receptor antagonist N, N-diethyl-2-[4-methoxy-3-(2-phenylethoxy)phenyl]ethanaminehydrochloride (NE-100) in the formation of form deprivation myopia (FDM) in guinea pigs.Methods:Eighty-five 21-day-old guinea pigs were selected, and 36 of them were randomly divided into normal control group, occluded 14-day group and occluded 11-day group, with 12 in each group.The right eyes of guinea pigs in the occluded 14-day group were covered with translucent eye shield for consecutive 14 days, and guinea pigs in the occluded 11-day group were treated in the same way for consecutive 11 days plus 3 days without cover, and guinea pigs in the normal control group were not covered.The other 49 guinea pigs were randomly divided into FDM group ( n=10), FDM+ NE-100 6 μg group ( n=12), FDM+ NE-100 60 μg group ( n=10), FDM+ NE-100 600 μg group ( n=9), and FDM+ saline group ( n=8). The right eyes in each group received 100 μl peribulbar injection of NE-100 6 μg, 60 μg and 600 μg or saline once a day according to grouping.Ocular refraction and axial dimensions were measured using eccentric infrared photorefractor and A-scan ultrasonography, respectively.Corneal curvature was measured with keratometer.Immunohistochemical staining and Western blot were used to detect the expression levels of Sigma-1 receptor protein, and retinal dopamine content was evaluated by high-performance liquid chromatography with electrochemical detection.This study was approved by an Ethics Committee of the Department of Laboratory Animal Science of Central South University (No.2020sydw0084). The use and care of experimental animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals in China. Results:There were statistical significant differences in diopter and axial length among the normal control group, occluded 14-day group and occluded 11-day group ( F=147.81, 160.10; both at P<0.01). Compared with the normal control group, the relative myopia was the deepest and the axial length was the longest in the occluded 14-day group, then the occluded 11-day group, showing significant differences between them (all at P<0.05). In the normal control group, Sigma-1 protein was mainly expressed in retinal ganglion cells (RGCs), photoreceptor inner segment and the inner nuclear layer.In the occluded 14-day group, Sigma-1 protein staining was enhanced in RGCs and photoreceptor inner segment.Sigma-1 staining positive cells in the inner nuclear layer were increased significantly and were also seen in the inner and outer plexiform layers, especially in Müller cells, in which the expression levels of Sigma-1 receptor protein were significantly increased.Compared with the occluded 14-day group, the Sigma-1 receptor protein expression levels in the retina of the occluded 11-day group was significantly decreased ( P<0.01). The diopters of guinea pigs in the FDM+ NE-100 6 μg, 60 μg and 600 μg groups were lower than those in the FDM group, and the diopters of FDM+ NE-100 60 μg and 600 μg guinea pigs were lower than those in the FDM+ NE-100 6 μg group, and the differences were statistically significant (all at P<0.05). The dopamine content in the retina of the FDM+ NE-100 60 μg group was (0.74±0.09) ng/mg, which was significantly higher than (0.57±0.10) ng/mg in the FDM group, with a significant difference between them ( t=15.18, P<0.01). Conclusions:Sigma-1 receptor antagonist inhibits FDM formation, which may be associated with the elevation of dopamine content in retina.

The patients were divided into sJIA-MAS and JSLE-MAS group，and the clinical manifestations，laboratory indicators and treatment of the two groups were compared.Results:Among the 48 children（14 males and 34 females）with MAS，the average age of onset was 9.5（3.0，11.8）years. There were 28 cases（11males and 17 females）of sJIA-MAS and 20 cases（3 males and 17 females）of JSLE- MAS. All the 48 children with MAS had fever and hyperferinemia，and the fever with sJIA-MAS was mostly continued fever or remittent fever. Respiratory tract infection was the most common trigger in sJIA-MAS［15 cases（53.6%）］，and disease activity was the most common trigger in JSLE-MAS［13 cases（65.0%）］.Additionally，viral infections（EB virus and cytomegalovirus）were also one of the triggers in MAS［sJIA：7 cases（25%），JSLE：4 cases（20%）］.Compared with JSLE-MAS，the number of days with fever［15.0（12.0，21.0）days vs. 6.0（4.0，9.5）days， Z=-3.812， P=0.001］and the length of hospital stay［29.0（26.3，39.8）days vs.26.0（19.3，30.8）days， Z=-1.958， P=0.049］were longer in sJIA. Compared with JSLE-MAS，ALT［（685.32±561.67）U/L vs.（139.61±124.44）U/L， t=4.973， P=0.001］，AST［784.00（235.25，1 251.25）U/L vs.189.50（53.25，374.08）U/L， Z=-3.283， P=0.001］，CRP［11.48（3.56，28.89）mg/L vs.1.91（0.53，8.98）mg/L， Z=-3.200， P=0.001］，ferritin［32 167.0（12 384.8，65 963.8）μg/L vs.2 003.5（922.5，11 430.0）μg/L， Z=-4.130， P=0.001］，ferritin max/ESR min［1 353.35（355.75，4 342.53）vs.91.92（34.94，291.53）， Z=-4.120， P=0.001］were higher in sJIA.The decrease of CRP was greater in sJIA［80.04（45.64，143.71）mg/L vs.10.20（6.27，25.64）mg/L， Z=-4.433， P=0.001］.Compared with sJIA-MAS，peripheral white blood cell counting［4.05（2.90，7.73）×10 9/L vs.1.56（1.15，3.47）×10 9/L， Z=-3.577， P=0.001］and platelet counting［（162.68±92.19）×10 9/L vs.（110.10±72.99）×10 9/L， t=2.118， P=0.040］were lower in JSLE-MAS. Kidney involvement was more common in JSLE-MAS［10 cases（50%）vs.0 cases（0%）， χ 2=17.684， P=0.001］.There was no significant difference in the incidence of sJIA-MAS and JSLE-MAS meeting the criteria of hemophagocytic lymphohistiocytosis［6 cases（21.4%）vs.5 cases（25.0%）， χ 2=0.084， P=0.772］. Conclusion:Compared with JSLE-MAS，sJIA-MAS is more dangerous and difficult to control，while JSLE-MAS involves more organs，among which the blood system and kidney are more common.
