Diagnostic value of renal phospholipase A2 receptor and serum anti-phospholipase A2 receptor antibody in membranous nephropathy / 中南大学学报(医学版)

Objective:To examine the expression ofphospholipase A2 receptor (PLA2R) in renal tissues and the level of anti-PLA2R antibody in serum in patients with idiopathic membranous nephropathy (IMN) and secondary membranous nephropathy (SMN),and to evaluate their diagnostic value in IMN.Methods:A total of 73 patients,who were diagnosed between May,2014 and February,2015 in the Department of Nephrology of the Second Xiangya Hospital,Central South University,were divided into three groups:an IMN group (n=48),an SMN group (n=17) and a minimal change disease group (n=8) according to the renal biopsy.PLA2R expression in renal tissues and the level of antiPLA2R antibody in serum were detected by indirect immunofluorescence technique.Results:The positive rate and fluorescence intensity for PLA2R in the renal tissues in the IMN group were higher than those in the SMN group (91.7％ in the IMN group vs 29.4％ in the SMN group,P＜0.05),while the positive rate and serum level for anti-PLA2R antibody in the IMN group were higher than those in the SMN group (85.4％ in the IMN group vs 29.4％ in the SMN group,P＜0.05);the expression of PLA2R in renal tissues and the serum level for anti-PLA2R antibody were not detected in the minimal change disease group,The serum level of anti-PLA2R antibody was positively correlated with 24 h urine protein (r=0.432,P＜0.01) and negatively correlated with serum albumin (r=-0.307,P＜0.05).Conclusion:The expression of PLA2R in renal tissues and the serum level of anti-PLA2R antibody might be potential markers for diagnosis oflMN.

Comparison of cisplatin-resistant testicular cancer cell lines established by two methods / 南方医科大学学报

<p><b>OBJECTIVE</b>To compare the biological behaviors of two drug-resistant testicular cancer cell lines established by different methods.</p><p><b>METHODS</b>Drug-resistance was induced in testicular cancer cell lines exposure of the cells to increasing concentrations of or a high dose of cisplatin (I-10/DDPi and I-10/DDPh cell lines, respectively). The morphological characteristics of the two cell lines were observed microscopically. The resistance index of the cells was determined with MTT assay, and the cell growth curves were drawn. The cellular expression of resistance-associated proteins MDR1 and P-gp was detected by Western blotting. The cell invasion ability was assessed with Transwell assay.</p><p><b>RESULTS</b>Normal testicular cancer cell line I-10 and the two resistant cell lines all showed an adherent growth pattern. Compared with I-10 cells, I-10/DDP cells exhibited slightly heterogenous cell sizes, irregular shapes, the presence of microvilli tentacles on the cell surface, and a scattered arrangement. The cisplatin resistance index of I-10/DDPi and I-10/DDPh cells were 3.924 and 3.099, respectively. Compared with I-10, the drug-resistant cell lines showed extended doubling time with increased expressions of MDR1 and P-gp and increased cell invasiveness, which was especially obvious in I-10/DDPi cells.</p><p><b>CONCLUSION</b>Both increasing dose exposure and high-dose exposure to cisplatin can induce cisplatin resistance in testicular cancer cells, and the resistant cells established by the latter method better mimics clinical drug-resistant tumor cells.</p>

Meta analysis on the relationship between 5-hydroxytryptamine 2A receptor gene polymorphism T102C and schizophrenia / 中华行为医学与脑科学杂志

Objective To assess the association of 5-hydroxytryptamine 2A (5-HT2A) receptor gene polymorphism with schizophrenia by Meta analysis.Methods Literatures on the relationship between 5-HT2A receptor gene polymorphism T102C and the Chinese schizophrenia in EMBASE,PubMed,CBM,CNKI and Wanfang Med Online were taken as research objects.Screening the relevant data according to the included and excluded standard,then,Software of RevMan 5.0 was employed to do Meta analysis.Meanwhile,we inspect the literatures publication bias.Results Twelve literatures were included,collecting 4 728 individuals,enrolling 2 135 for the schizophrenia group and 2 593 for the control group.The research conforms to Hardy Weinberg equilibrium (all P＞0.05).The Meta analysis results showed that there was no significant association between 5-HT2A receptor gene polymorphism and schizophrenia including the allele model,recessive model and codominant model genotypes (all P＞ 0.05).The results of Dominant genetic model I2 =45％ with moderate heterogeneity,but we used subgroup analysis to remove the author Ni's data,there were significant difference analysis (I2=9％,Z=2.01,P＜0.05).Conclusions 5-HT2A receptor gene T102C site C allele is recessive genes,CC may be a healing factor,there needs evidence-based study provides further evidence.

Application value of adjuvant inhalation of hyperbaric oxygen in viability and life quality of postoperative patients with malignant gliomas / 中华神经医学杂志

Objective To explore the influence of chemoradiotherapy combined with inhalation of hyperbaric oxygen in short-term therapeutic effectiveness,viability and quality of life of postoperative patients with malignant gliomas.Methods A total of 86 patients with malignant gliomas,admitted to our hospital from January 2009 to December 2013,were chosen in our study; according to the wishes of patients and their families,all patients were divided into two groups:chemoradiotherapy combined with inhalation of hyperbaric oxygen group (n=47) and chemoradiotherapy group (n=39).Chemotherapy regimens were given:temozolomide of 150 mg/m2 body surface area at the first period once daily for a consecutive five days and temozolomide of 200 mg/m2 body surface area since the second period once daily for consecutive five days.Hyperbaric oxygen therapy was given with duration of 60 min at pressure of 2.8 atm.Conventional radiotherapy (6000 cGy/30F) was given in both groups.WHO established solid tumor chemosensitivity criteria was used to evaluate the effective rate of total symptoms,and activity of daily living (ADL) scale and F-36 scale were employed to evaluate the viability and life quality before and three and six months after the intervention.Results The effective rate of total symptoms,ratio of ADL＞60 points in chemoradiotherapy combined with inhalation of hyperbaric oxygen group 3 and 6 months after treatment were 95.74 ％,53.2％ and 72.3％,which were significantly higher than those in the chemoradiotherapy group (58.97 ％,30.8％ and 48.7％,P＜0.05).The scores of all the items of SF-36 scale in chemoradiotherapy combined with inhalation of hyperbaric oxygen group 3 and 6 months after treatment were significantly higher than those in the chemoradiotherapy group (P＜0.05).Conclusion Inhalation of hyperbaric oxygen can significantly improve short-term therapeutic effectiveness,survival duration,viability and quality of life of postoperative patients with malignant gliomas,and obviously improve the prognosis of patients.

Effects of different postoperative drainages on preventing anastomotic leakage after Dixon operation in rectal carcinomas / 国际外科学杂志

Objective To investigate prospectively effects of different drainage methods on preventing anastomotie leakage after Dixon operation in rectal carcinomas.Methods During the period of January 2002 to January 2007,450 patients with rectal carcinomas received Dixon operation.They were divided into three groups ( group A,B,and C) in order of admission.Presacral drainage was done in Group A,presaeral drainage + drainage through anus with one tubes in Group B,and presacral drainage + drainage through anus with two tubes in Group C.The postoperative complications of three groups were observed.Results There was 7.33% (11/150) ,8.00% (12/150) and 6.67% (10/150) wound infection in group A,B and C respectively.8.67% (13/150),6.67% (10/150) and 1.33% (2/150) anastomotic leakage occurred in group A,B and C respectively.Three groups had a similar wound infection ineidence(P ＞0.05).The occurrence of anastomotic leakage in group C was statistically lower than that in group A and B ( P ＜ 0.05 ).Conclusion Presacral drainage + drainage through anus with two tubes can effectively prevent anastomotic leakage after Dixon operation in rectal carcinomas.
