Objective To explore the influence of type A character on early renal impairment in elderly patients with essential hypertension and the protective effect of benazepril. Methods According to the type A behavior measuring scale, 80 cases with type A character and 80 cases without type A character were screened out from the elderly patients with essential hypertension. The patients received benazepril intervention with incipient dose of 10 mg daily, which increased gradually to the largest does of 20 mg daily within 1 month, The treatment lasted 6 months in order to make the patients achieve the normal blood pressure (BP). The general data, plasma angiotensin Ⅱ (AngⅡ )> urinary albumin excretion rate (UAER) and urinary β2-microglobulin (β2-MG) were measured at pretherapy and post-treatment respectively. Results There were no statistically significant differences at pretherapy between the two groups in age, gender, body mass index (BMI), blood urea nitrogen (BUN), creatinine (Cr), systolic pressure and diastolic pressure (all P>0.05). Ang Ⅱ [(60.3±11.6)mg/Lvs (55.8±10.2)mg/L], UAER[(83.3±23.3)μg/min vs. (75.7±16.3)μg/min] and β2-MG [(75.6±24.5)mmol/L vs. (66.0±19.4)mmol/L] were significantly higher in type A character group than in non-type A character group (t=2.598, 2.603, 2.742; P= 0.016,0.012, 0.008). TypeA character value of the two groups showed a positive correlation with Ang Ⅱ (r= 0.361, P=0.002), UAER (r=0.198, P=0.015) and β2-MG (r=0.202, P = 0.021). Only Ang Ⅱ (β=0.291, t=2.793, P= 0.008) was correlated to type A character value independently by multiple stepwise regression analysis. Before treatment in both of the type A character group and the non-type-A character group, there was a positive correlation between Ang II and UAER, (β2-MG, and obvious correlation in type-A character group. The systolic pressure, diastolic pressure, Ang Ⅱ , UREA and β2-MG were all decreased obviously in two groups post treatment. And the variable value of AngⅡ was also positively correlated with UAER (r=0.373, P=0.005; r=0.282, P=0.032), fr-MG (r= 0.385, P=0.003; r= 0.279, P=0.039) before and after treatment. Conclusions Type A character can aggravate injury of early renal function by certain stress systems in the elderly patients with essential hypertension and benazepril has better protective effect for it.

Objective To construct and express human ScFv against keratin in E.coli,and identify its binding activity with antigens and antigenic specificity.Methods By genetic engineering technology,human anti-keratin ScFv was constructed from Fab fragment selected from established semi-synthetic phage antibody library.The binding activity with antigens and antigenic specificity of expressed products were i-dentified by ELISA.Results Results of DNA sequence analysis showed that nucleotide sequence of V?and VH of ScFv gene was similar to that of V?and VH of Fab gene,suggesting that there was no mutation in the construction of ScFv.The soluble anti-keratin ScFv was found to have a good antigenic specificity as well as excellent binding activity with target antigens by ELISA.However,the binding activity of ScFv with keratin was lower than that of Fab.Conclusions The successful expression and identification of human an-ti-keratin ScFv might lay a solid foundation for further observation of biological activities of anti-keratin au-toantibody,manufacture of genetic-engineering anti-keratin products,and promotion of clinical application of genetic-engineering anti-keratin antibodies.

Aim To observe the production of anti-idiotypic antibodies directed against AK auto Ab in the rabbit sera after long-term, high dose allogenic AK auto Ab injection. Methods Allogenic AK auto Ab (5mg/kg)was injected intramuscularly to rabbit once every other day for 90 days. Anti-idiotypic antibodies in rabbit sera were detected by ELISA. Results Rabbits injected with AK auto Ab generated anti-idiotypic antibodies that could react to F(ab′ )2 of AK auto Ab. The titers of anti-idiotypic antibodies reached the highest levels at 4 weeks after the administration of AK auto Ab and then gradually decreased. Conclusion Rabbits could be induced to form immune tolerance when high-does allogenic AK auto Ab is administrated for long-term.

[Summary] Four patients with hyperthyroid-associated exophthalmos, myxedema, acropachy ( EMA ) syndrome, including three male patients and one female patient were diagnosed with Graves′diseases and treated by 131 I therapy. Complaints of thyrotoxicosis were presented at the onset. Tibia myxedema and acropathy appeared, and eye symptoms aggravated in two patients after anti-thyroid drug therapy and 131 I therapy. Four cases were all given clobetasol propionate, miconazole nitrate, neomycin sulfate and urea cream alone or in combination with compound betamethasone local injection treatment, and three cases were given low-dose oral prednisone treatment. Complaints of tibia myxedema and eye symptoms were significantly improved after the treatment. Therefore, we should be wary of the occurrence of hyperthyroid-associated EMA syndrome after 131 I therapy. Corticosteroid might be the effective therapy for myxedema and eye symptoms of EMA syndrome.

Objective:To evaluate the early side effects and influencing factors in patients undergoing intensity-modulated radiation therapy after cervical cancer surgery.Methods:A retrospective analysis of 106 patients with cervical cancer who underwent postoperative intensity-modulated radiation therapy in our hospital from January 2014 to December 2017 was conducted. The occurrence of toxic and side effects were summarized, and the related clinical indicators were analyzed using univariate and multivariate analyses.Results:The 3-year overall survival rate was 88.1%, and the 3-year progression-free survival rate was 84.8%. The incidence of acute hematologic toxicity greater than grade 3 was 33%. The incidence of early intestinal reactions was 35%, of which only 1.8% was greater than grade 3. Univariate analysis demonstrated that severe acute hematologic side effects were statistically significant ( χ2=1.789-17.895, P<0.05) with the level of hemoglobin before radiotherapy, radiation in the abdominal aortic lymphatic drainage area or not, an increase of local radiotherapy dose in the target area, and chemotherapy or not. Multivariate analysis showed that concurrent chemotherapy significantly increased the incidence of severe acute hematologic toxicity ( χ2=3.929, P<0.05). Conclusions:In patients with cervical cancer undergoing postoperative intensity-modulated radiation therapy, grade 3 and greater toxic side effects are mainly related to hematological toxicity, and the incidence of severe bowel toxicity in the early stage is low.

Objective:To analyze and screen the key genes of sepsis secondary to pulmonary infection by bioinformatics, and to provide theoretical basis for the basic research of the disease and find an ideal animal model program.Methods:Experiment 1 (bioinformatics analysis): gene expression data sets of pulmonary infection secondary sepsis patients and multiple sepsis animal models were screened by Gene Expression Omnibus (GEO) Database, and gene differences were analyzed by R software. Differential genes were analyzed by gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Correlation analysis was conducted between differential genes and clinical symptoms in the data set of pulmonary infection secondary sepsis, and the correlation heat map between differential genes and clinical symptoms was drawn. Key genes were screened by weighted gene co-expression network analysis (WGCNA) and protein-protein interaction network analysis (PPIN) clustering. Experiment 2 (sepsis animal model preparation): male mice weighing 21-25 g were randomly divided into the key genes group and the control (Sham) group. And cecal ligation and puncture (CLP) was used to establish mouse sepsis model, while the mice in sham group were performed by exposure of cecum. And all the mice were scarified 24 hours after surgery to extract the total RNA from lung tissue, real time fluorescent quantitative polymerase chain reaction (RT-qPCR) was used to detect mRNA expression of key genes.Results:Experiment 1 (bioinformatics analysis): 319 differential genes were showed by GSE 134364 and GSE 65682 data set analysis of pulmonary infection secondary sepsis. And there was no genetic difference between community acquired pneumonia (CAP) and hospital acquired pneumonia (HAP) in patients with pulmonary infection secondary to sepsis. Obvious differences existed between differential genes in animal models, and there was no common differential gene. Differential genes in patients and animal models were similarly enriched in GO function, mainly in cell differentiation, regulation of cell process, and regulation of cellular response to stimuli, there were significant differences in pathway enrichment, among which, CLP animal models showed higher consistency with patients. The key genes obtained by WGCNA and PPIN analysis were MAPK14, NLRC4 and LCN2. Experiment 2 (sepsis animal model preparation): animal experiment results showed that the mRNA expressions of MAPK14, NLRC4 and LCN2 in lung tissue of CLP model mice were significantly up-regulated compared with the sham group.Conclusions:MAPK14, NLRC4 and LCN2 are key genes involved in the regulation of biological processes of pulmonary sepsis secondary to infection, and are potential research directions of this disease. What's more, CLP animal model can better reflect the biological characteristics of patients with pulmonary infection secondary sepsis, and is one of the ideal animal model schemes for pulmonary infection secondary sepsis.
