AIM: To investigate the effects and mechanisms of swainsonine-induced apoptosis on SGC-7901 cells. METHODES: After being treated with swainsonine, effective dose and median inhibition concentration (IC50) of swainsonine to SGC-7901 cells were examined by MTT assay. Cell cycle distribution and apoptotic rates were analyzed by flow cytometry. Expression of p53, c-myc and Bcl-2 were determined by immunocyto- chemical method, and the concentration of Ca2+ intra-cellular ([Ca2+]i ) was measured by the laser scanning confocal microscope (LSCM). RESULTS: Swainsonine inhibited cell growth of SGC-7901 in vitro, IC50 of 24 h was 0.84 μg·ml-l, and complete inhibition concentration of swainsonine was 6.2 μg·ml-l. Treated with swainsonine at the concentrations of 0.5, 1.5 and 4.5 μg·ml-l for 24 h, the expression of apoptosis inhibiting gene p53 and bcl-2 decreased, and apoptotic trigger gene c-myc increased (P<0.05), as well as [Ca2+]i overloading, SGC-7901 cell was induced to apoptosis in the end. The percentage of S phase were 38.8%, 39.7% and 29.6%, respectively (20.0% in control group and 23.2% in 5-Fu group), the percentage of G2/M phase were 4.5%, 1.7% and 5.3%, respectively (5.5% in control group and 9.0% in 5-Fu group), and the percentage of G1/M phase was not altered. SGC-7901 cells were treated by swainsonine at the concentrations of 0.5, 1.5 and 4.5 μg·ml-l for 24 h. Compared with the control group, the percentage of S phase were increased and that of G2/M cells were decreased significantly in treatment groups (P<0.01). CONCLUSION: Swainsonine can inhibit the cell proliferation and induce apoptosis of SGC-7901 cells, the mechanisms of swainsonine-induced apoptosis may related with [Ca2+]i overloading and expression of apoptosis-related genes.

Objective To investigate the relevance between protein expression and methylation of MG-MT and hMSH2 in glioma patimts.Methods Immunohistochemical and methylation specific PCR were adopted respectively to test on 275 cases of glioma patients for the protein expression and methylation situation of MGMT and hMSH2.Results The negative protein expression rate of MGMT and hMSH 2 in the tissue of brain golima were 47.2% and 62.5% respectively;the occurrence of methylation in gene promoter region were accordingly 41.8% and 22.4%.Statistical analysis revealed that MGMT promoter methylation in peripheral blood gene groups was related with the protein negative expression of tumor tissue (P<0.05),while there was no relationship between the protein expression of hMSH2 and its gene promoter methylation(P>0.05).Conclusion The meth-ylation of MGMT is a common molecular situation in the generation of brain glioma ,which may be connected with that of tumor.However,hMSH2 promoter methylation might not the main reason for inactivation of hMSH 2 pro-tein,there may be other important factors affecting its expression .

Objective To investigate the relationship between the single nucleotide polymorphism in exon 7(G894T) or the insert/deletion polymorphism of variable number of tandem repeat in intron 4(4b/a) of the endothelial constitutive nitric oxide synthase(ecNOS) gene and the coronary disease in patients with type 2 diabetes.Methods In 80 patients with type 2 diabetes(group DM),92 type 2 diabetic patients with coronary disease(group DH) and 119 healthy controls(group NC),the polymorphism G894T was determined by polymerase chain reaction-restriction fragment length polymorphism analysis, while the polymorphism 4b/a was determined by polymerase chain reaction-variable number of tandem repeat analysis.Results The frequencies of allele T or genotype containing with allele T(GT or TT) in group DH were significantly higher than those in group DM or group NC(all P

Objective:To study the anti-depression mechanism of Chaiyuwendan Decoction(CYWDD).Methods:Rat models were established by separation and chronic unpredictable mild stress(CUMS).Ethology of rats were detected by open-field test and sucrose consumption test,contents of monoamine neurotransmitters were detected by HPLC-ECD.Results:Compared with normal group,the weight,the frequency of crossing,rearing and the contents of consumption to sucrosum water in depressive disorder rats decreased significantly(P

Objective To study biological effect of recombinant human erythropoietin ( RhEPO) on the expression of oligodendrocyte in the neuron glia antigen 2 ( NG2 ) , Nogo receptor-interacting protein 1 (LINGO-1), myelin basic protein (MBP) and myelin associated glycoprotein (MAG), and to explore the protective mechanism of RhEPO for oligodendrocyte after cerebral infarction.Methods Experimental rats were randomly divided into the treatment group ( RhEPO at a dose of 3 000 U/kg) or saline control group.Both groups received intraperitoneal injection of RhEPO after cerebral ischemia in 30 min, 3 h, 6 h, 12 h and 24 h, which was administered daily for 7 days.The modified neurological severity score ( mNSS) and histology were analyzed, and immunohistochemistry was used to detect the protein expression of NG2, MAG, MBP and LINGO-1.Results The overall mNSS of RhEPO treatment group significantly decreased compared with the saline control group on the seventh day after cerebral infarction ( P<0.05 ).Such treatment effect was more obvious in the treatment group at 30 min and 3 h ( P<0.01).Compared with the saline control group, the numbers of NG2 positive cells increased in RhEPO treatment group.In contrast, the expression of LINGO-1 protein significantly decreased (P<0.05), with a dramatic decrease observed at 30 min and 3 h ( P<0.01).However, the expression of MBP protein decreased more significantly in saline control group, while the level of the MAG protein expression increased.The differences were statistically significant ( P<0.05), especially at 30 min (P<0.01).Conclusions After cerebral ischemia, RhEPO promotes the proliferation of NG2 positive cells, and inhibits the expression of LINGO-1 and MAG proteins.RhEPO improves the proliferation and differentiation of oligodendrocyte precursor cells, which in turn protects neuronal function, particularly at the early phase of ischemia.

Objective:To explore the clinical characteristics, diagnosis and treatment of cryptococcal infection after renal transplantation.Methods:The clinical data were analyzed retrospectively for 17 hospitalized cases of cryptococcal infection after kidney transplantation from January 2003 to December 2019. The relevant parameters included site of infection, clinical manifestations, complications, comorbidities, treatments and outcomes. The average time to infection after transplantation was (7.9±5.4) years, the median baseline level of creatinine was 137(75-741) μmol/L. Concurrent conditions included hypertension (n=15, 88.2%), diabetes (n=6, 35.3%) and chronic hepatitis (n=9, 52.9%). The most common site of infection was central nervous system (88.2%), followed by lungs (29.4%) and skin (17.6%).Results:The clinical manifestations were diverse. Most patients received amphotericin B liposome and/or fluconazole as an initial option. The outcomes were curing (n=17, 58.8%), death from cryptococcal infection (n=5, 29.4%), partial relief (n=1, 5.9%) and stable disease (n=1, 5.9%). Among 10 curative cases, 2 cases died from other causes and 4 cases returned to hemodialysis with graft loss.Conclusions:Cryptococcosis is typically a late-occurring infection in kidney transplant recipients. Many factors, such as complications, nonstandard antifungal treatment, immune dysbalance, have adverse prognoses. Strengthening follow-ups, dealing with complications, validating the diagnosis early, interdepartmental cooperations, standardizing antifungal therapy and balancing immune status may improve the outcomes of cryptococcosis after kidney transplantation.

Objective:To explore the clinical characteristics and risk factors of pediatric kidney transplantation (KT).Methods:From January 1, 2010 to September 30, 2022, retrospective analysis was performed for the relevant clinical data of 81 pediatric recipients of primary KT at Organ Transplant Center of Shanghai Changzheng Hospital. The occurrences of acute rejection (AR) ,delayed graft function (DGF), infection, myelosuppression, tumor and other complications were observed within 1 year post-KT. They were grouped according to whether or not AR/DGF occurred. Univariate analysis speculated the effect of AR and DGF on renal function at 1 year after transplantation. Binary Logistic regression was employed for examining the risk factors related to AR/DGF.Results:During follow-ups, transplanted kidney was removed due to an embolization of renal vessels and dialysis resumed (n= 5). One child had failed graft due to the recurrence of original disease and dialysis resumed. The remaining 75 children had an excellent recovery of graft function. At the end of follow-ups, survival for transplant recipients and transplanted kidneys was 100% (81/81 ) and 92.6% (75/81) respectively. 23 patients (28.4%) developed DGF, including 20 child recipients of C-I donors. Among DGF recipients, 21 (91.3%) were immune induced with anti-CD25 humanized monoclonal antibody and 2 (8.7 %) with porcine antihuman lymphocyte immunoglobulin (pALG). Within the first year post-KT, 13 patients (16.1%) developed AR, including 11 child recipients of C-I donors. Induction was made with anti-CD25 humanized monoclonal antibody (n=8), pALG (n=4) and anti-human T lymphocyte rabbit immunoglobulin (n=1). And 12 cases were reversed with MP (methylprednisolone) shock therapy while another ineffective case was rescued by an intravenous infusion of rATG (rabbit anti-human thymocyte immunoglobulin). During postoperative follow-ups, 14 (17.3 %) KT recipients had an onset of pulmonary infection (n=7), upper respiratory tract infection (n=3), urinary tract infection (n=5), gastrointestinal infection (n=2) and abdominal cavity infection (n=1). The causative pathogens were bacteria (n=14) and viruses (n=4). Among 7 cases (8.6%) of myelosuppression, there were leukopenia (n=6) and thrombocytopenia (n=1 ). During 1-year follow-ups, no malignancy occurred. At the last follow-up, blood creatinine was (72.79±21.07) μmol/L in non-AR/DGF recipients. For AR/DGF recipients, blood creatinine levels were (68.83±10.78) and (74.20±18.70) μmol/L. There was no significant inter-group difference ( F=0.14, P=0.87). In groups with and without DGF, the incidence of bone marrow suppression in the children with DGF was significantly higher (21. 74 %) than that in the untreated group (3.45%), with a statistically significant difference ( P=0.02). However, there was no statistically significant difference in the age, sex, donor source, infection, and types of immune-induced drugs in AR, DGF occurrence and no occurrence group. logistic Regression analysis showed that immunoinduction therapy with lymphocyte inhibitor ( OR=0.074, 95 %CI: 0.009-0.0643, P=0.018) and bone marrow suppression ( OR=0.045, 95%CI: 0.004-0.515, P=0.013) were risk factors for DGF. Conclusion:KT in children may obtain decent outcomes. Immunoinduction therapy with lymphocyte inhibitors and occurrence of myelosuppression are risk factors for postoperative DGF. The occurrence of AR/DGF in early postoperative period does not affect the level of kidney function in children at 1 year post-KT. It is recommended to closely follow up and accumulate experiences for optimizing long-term outcomes.

Objective To measure the reliability and validity of the Chinese version of the compre-hensive assessment of ACT processes(CompACT)in financial staffs. Methods A total of 3 735 valid ques-tionnaires were obtained from financial staffs.The valid questionnaires were randomly allocated into two groups,of which one subset(n=1 873)was used for exploratory factor analysis(EPA),and the other(n=1 845)for confirmatory factor analysis(CFA).Criterion and convergent validity were tested by Pearson corre-lation respectively.Incremental validity was tested by hierarchical regression analysis. Results The EFA suggested theoretically-coherent three-factor structure for a 15-itemed version of the CompACT.The three fac-tors named as acceptance and cognitive defusion,mindfulness and self as context,value and committed ac-tion,and explained 73.75% of the total variance and factor loadings ranged from 0.67 to 0.90.The CFA con-firmed the hypothesized three-factor mode(χ2/df=5.91,CFI=0.98,TLI=0.98,RMSEA=0.05). Conclu-sion The research suggests that the Chinese version of the CompACT has acceptable psychometric in prop-erties,so it can be applied in the assessment of the psychological flexibility and mental health in China.
