Journal of Chongqing Medical University 2007;0(11):-
Objective:To observe the inhibitory effect of disodium cantharidinate on human hepatoma cell line HepG2 and investi-gate its possible mechanisms. Methods:HepG2 cells were treated with different concentration of disodium cantharidinate,The in- hibiton of cell proliferation,cell cycle distribution,expression of Survivin and activity of Caspase-3 were respectively evaluated by MTT assay,flow cytometry,immunocytochemistry,and chromatometry. Results:Disodium cantharidinate could inhibit the proliferation of HepG2 cells. The IC50 at 24,48,72 h after intervention were 2.41?0.48,0.72?0.08,and 0.39?0.04 ug/ml,The cells of G2/M phase and activity of Caspase-3 were increased.the expression respectively of Survivin were inhibited after the intervention of disodium cantharidinate. Conclusion:The inhibitory effect of disodium cantharidinate on HepG2 cells may be mediated by the block of cellcycle,enhancement of Caspase-3,and inhibition of Survivin.

Chinese Journal of Medical Education Research 2016;15(7):684-690
Objective To explore the feasibility and effect of the multivariate integration teaching in clinical nursing teaching, improve the shortcomings of the traditional single teaching, and enhance the quality of clinical teaching and nursing students' satisfaction. Methods 117 clinical nursing students of the Department of Rheumatoid Immune Kidney of the Nanjing Hospital Affiliated to Nanjing Medical Uni-versity were chosen as the subjects and were divided into two groups, and 57 nursing students who practiced in the Department of Rheumatoid Immune Kidney from 2013 to 2014 were recruited to the experimental group to receive multivariate integration teaching method, with another 60 students who practiced in the Department of Rheumatoid Immune Kidney from 2012 to 2013 as control group to receive the traditional single model teaching method. Two groups of nursing students were given the unified theory test and clinical skills exam-ination as well as the evaluation of comprehensive quality and satisfaction survey. SPSS 20.0 software was used to give the general statistical description of the theoretical results, operating results, comprehensive quality, satisfaction and other measurement data. Examination results were expressed by x±s. t test, rank sum test was used for statistical analysis and the test level was α=0.05. Results Theoretical result of the experimental group was (96.283±2.330), operating result was (93.883±3.173), the compre-hensive quality evaluation result was (46.133±2.111), and satisfaction degree was (45.033 ± 5.966). Theo-retical result of the control group was (87.850 ± 4.953), operating result was (84.333±5.011), the com-prehensive quality evaluation result was (35.650 ±3.804), and satisfaction degree was (33.683 ±7.101). Conclusion Multi-variate integration teaching method is conducive to the cultivation of nursing students' clinical thinking and comprehensive quality, and can improve their ability to communicate with patients and enhance their self-confidence. Therefore it is an effective teaching method, worthy of popularization and application in all departments.
6.Effect of caveolin-1 on renal injury and the expression of tight junction protein in MRL/lpr mice kidney
Chinese Journal of Rheumatology 2016;20(6):364-367
Objective To study the effect of caveolin-1 on renal injury and the expression of tight junction proteins in MRL/lpr mice kidney.Methods The mice were divided into 4 groups:5 mice in the normal control group (BALB/c mice);the MRL/lpr lupus mice (n=18) were randomly divided into the MRL/lpr group in which 6 mice were included;the negative control group in which 6 mice were included;the caveolin1 transfection group in which 6 mice were included.The changes of urine protein,the levels of urea (BUN) and creatinine (Cr) were detected.The expressions of claudin-5,occludin,ZO-1 and caveolin-1 protein were determined by western bloting.Analysis of variance was used to determine statistical significant differences between the two groups.A significance level of 0.05 was considered as signigicant.Results Compared with the control group,24 h urine protein [(2 894±437) mg,(412±72) mg],BUN [(8.7±1.5) mmol/L,(6.9±0.4) mmol/L],Cr [(106±22) μmol/L,(85±4) μmol/L] were significantly increased,level of caveolin-1 protein increased (265±17,61±6),the level of occludin (114±12,190±12),claudin-5 (60±5,80±6) and ZO-1 (98±11,206±15) protein decreased in the MRL/lpr group (P<0.05).After caveolin-1 transfection,the levels of urinary protein [(1 253±249) mg,(2 894±437) mg],BUN [(6.5±1.3) mmol/L,(8.7±1.5) mmol/L],Cr [(78±17) μmol/L,(106±22)μmol/L] were significantly decreased,and the levels of occludin (218±16,114±12),claudin-5 (87±6,60±5)ZO-1 (313±17,98±11) were increased (P<0.05).Conclusion The expression of caveolin-1 protein in the renal tissues of lupus nephritis increases.Caveolin-1 can reduce the expression of tight junction proteins and contribute to progres-sion of lupus nephritis.
7.Chronic periodontitis with Takayasu arteritis:a case report
Journal of Peking University(Health Sciences) 2015;(5):875-877
SUMMARY This case report concerns a 23-year-old woman with chronic periodontitis who had been pre-viously diagnosed with Takayasu arteritis ( TA ) .Her erythrocyte sedimentation rate ( ESR ) and C-reactive protein ( CRP) level were decreased before and 3 months after non-surgical periodontal therapy with no change in her prescribed medications (ESR from 31.00 mm/h to 23.0 mm/h, CRP from 21.40 mg/L to 18.46 mm/h).Through the occasional findings , we raised a hypothetical analysis about the po-tential relationship between periodontitis and TA with respect to inflammatory factors , bacteria and medi-cation.Further studies of large samples are needed to verify the findings .
8.Recent advances on treatment of primary central nervous system lymphoma
Journal of Leukemia & Lymphoma 2012;21(5):312-314
Primary CNS lymphoma (PCNSL) is a rare malignancy with peculiar clinical and biologic features,aggressive course,and unsatisfactory outcome.the particular microenvironment of this malignancy,and sanctuary sites where tumor cells grow undisturbed, strongly affects treatment efficacy. The execution of prospective trials is also difficult because of the rarity of the tumor and the impaired general condition and poor performance status of patients. Chemotherapy is indispensable for the treatment of PCNSL. High-dose methotrexate is the most effctive drug.PCNSL is sensitive to irradiation,but responses to radiotherapy alone are short-lived. MTX-based chemotherapy followed by whole-brain radiotherapy prolonged survival but is associated with delayed neurotoxicity especially in patients older than 60 years. A new approach is attempted to treat PCNSL with chemotherapy alone with defered radiotherapy in old patients with similar survival rencenfly. High-dose chemotherapy with autologous stem cell transplantation HDC/ASCT yielded promising results for recurent PCNSL.Clinical investigation with Temozolomide or rituximab have been reported.Further studies with these new drugs are needed.

Chinese Journal of Rheumatology 2014;18(11):773-776
Objective To study the effect of hydroxychloroquine (HCQ) on the suppressors of cytokine signaling (SOCS) in the kidney of MRL/lpr mice and evaluate the protection of HCQ on lupus nephritis.Methods Twenty-six rats were randomly divided into 3 groups:the control group which was consisted of 6 mice; the MRL/lpr group which was consisted of 10 mice; and the HCQ group which was consisted of 10.24-hour urinary protein level and anti dsDNA levels were tested.The expressions of SOCS-1 and SOCS-3 protein were determined by western blot.Analysis of variance was used to determine statistically significant differences between the two groups.A P value less than 0.05 was considered to be statistically significant.Results Compared with the control group,the levels of 24-hour urinary protein [(2 356.6±509.3) mg vs (440.3±90.1)mg] and anti ds-DNA (128.7±32.3 vs 14.9±1.4) were significantly increased in the MRL/lpr group,the expression levels of SOCS-1 and SOCS-3 protein were increased.After treated with HCQ,the levels of 24-hour urinary protein [(70.8±11.1) mg vs (2 356.6±509.3) mg] and anti-dsDNA (111.8±330.1 vs 128.7±32.3)were significantly decreased,the expression level of SOCS-1 and SOCS-3 protein decreased significantly (P< 0.05).Conclusion HCQ can inhibit SOCS expression in the kidney of lupus mice,reduce proteinuria and delay progression of immune disorders and lupus nephritis.
