The spectrum of glomerulonephritis differs in different countries and areas all over the world,and changes with socioeconomic progression. Recent researches have shown that the difference and change of the spectrum of glomerulonephritis are correlated with Th1 and Th2 immune responses."Hygiene hypothesis" is also proposed.

OBJECTIVE:To study pharmacokinetics of cyclosporine in healthy volunteers, and to investigate the relationship of drug exposure with blood sampling time after treatment. METHODS: The data of trial at the first 12 blood sampling time points after medication were collected from bioequivalence test in 24 healthy volunteers (trial preparation vs. reference preparation). Multiple linear regression analysis was used to study the blood concentrations of cyclosporine at different sampling time points and the area under the blood concentration-time curve (AUC). RESULTS: The concentrations at two points were adopted to estimate AUC. The correlation coefficient of different cyclosporines could reach 0.9 with estimation deviations less than 15%. The AUC of cyclosporine of trial preparation could be estimated by C8 and C12, and that of reference preparation by C2.5 and C12. CONCLUSION: The AUC estimated by concentrations at two points can meet clinical demand. There is great difference in estimate point among different preparations.

Objective To explore the impact of chronic cough on children’s life quality, and to observe their life quality after drugs and psychological intervention. Methods One hundred 9 to 12 years old children with chronic cough were randomly selected. The drugs and psychological intervention were administrated. The children had been follow-up. The children’s quality of life was assessed by“Inventroy of Subjective Life Questionnaire”before and after treatment. Meanwhile 100 healthy children were randomly selected as a control group. Results With the prolonged treatment, the recovery rate and effective rate in children with chronic cough increased. Before the treatment, the scores of family life, peer interaction, self cognitive, experience of depression, experience of anxiety, cognitive and emotional component, and overall satisfaction were significantly lower in children with chronic cough than those in healthy children (P<0.05). After the treatment, the scores of family life, peer interaction, self cognitive, experience of depression, experience of anxiety, physical experience, cognitive and emotional component, and overall satisfaction were significantly improved in children with chronic cough (P<0.05), even the scores of physical experience and emotional component were significantly higher in children with chronic cough than those in healthy children (P<0.05). Conclusions The quality of life in children with chronic cough decline, however, drug and psychological intervention can improve their quality of life.

Objective To explore the role of σ1 receptor (σ1R) in the clinical prognosis of cervical cancer,and provide a theoretical basis for σ1R targeted molecular therapy through observing the inhibition of synthetic σ1R-specific ligand compounds on the growth of cervical cancer cells. Methods (1) Immunohistochemical or immunocytochemistry staining were respectively used to detect the expression and localization of σ1R protein.(2)The Cancer Genome Atlas (TCGA) data set was used to validate our results. (3)Two series of 4 novel σ1R ligand compounds were synthesized by altering the N-terminal substituents on the piperidine ring of the prezamicol analogue, named as 14a, 14e, 15c and 15f. Methyl thiazolyl-tetrazolium (MTT) assay was detect the anti-proliferative effect of the four compounds on HeLa and SiHa cells. Compound 14a with potent inhibitory activity and the highest specificity of σ1R was selected for further experiments. Scratch test was observed the migration effect of compound 14a on HeLa and SiHa cells. Flow cytometry was determined cell cycles and apoptosis. Results (1) Immunostaining of σ1R protein was located in the cytoplasm and nucleus of cervical epithelium. The expression of cervical squamous cell carcinoma (SCC) was significantly higher than those of high-grade squamous intraepithelial lesion (HSIL) or normal cervical tissues. There was no significant difference in the expression of σ1R between HSIL and normal cervical tissues. σ1R expression in cervical adenocarcinoma (AC) was higher than that in SCC (P=0.020). The nuclear expression rate of σ1R in AC (10/18) was higher than that of SCC (27.1%, 19/70; P=0.024). The median overall survival (MOS) of σ1R-positive SCC patients was lower than that of σ1R-negative patients [(45.8±3.1) vs (51.7±2.9) months, P=0.045]. MOS of the patients with σ1R nuclear positive SCC was lower than that of non-nuclear staining [(38.9±3.8) vs (48.7±2.1) months, P=0.022]. MOS of the patients with σ1R nuclear positive AC was lower than that of non-nuclear staining [(35.0± 6.3) vs (44.2±4.2) months, P=0.034]. (2) Analysis of TCGA data showed that σ1R expression of in SCC was correlated with age (P=0.005). σ1R expression in AC was significantly associated with advanced stage, lymphnode metastasis and vascular invasion (all P<0.05). MOS of AC patients with σ1R overexpression was significantly lower than that of the patients with low expression (P=0.034). There was no significant difference in the MOS of different expression of σ1R mRNA in SCC patients(P=0.930). (3) MTT assay showed that these four compounds could suppressed the growth of HeLa and SiHa cells in time- and dose-dependent manner. The growth inhibition rates of HeLa and SiHa cells at 48 hours treated by combination of different concentrations of nedaplatin (NDP) with compound 14a (6 μmol/L) were significantly higher than those treated by NDP alone. Compound 14a (30 μmol/L) significantly inhibited the migration (both P<0.01) and induced the apoptosis of HeLa or SiHa cells (both P<0.01). Conclusions σ1R is over-expressed in cervical cancer and HSIL. σ1R nuclear expression is an important marker of AC. σ1R over-expression, especially σ1R nuclear expression is associated with the poor prognosis of cervical cancer. Our study is mostly consistent with cervical cancer data of TCGA. These results suggest that the novel synthetic prezamicol analogues 14a for σ1R could inhibit the growth of cervical cancer cells and cell migration through inducing apoptosis and arresting cell cycle in G0/G1 period, enhance NDP-induced cytotoxicity.

Objective To analyze the clinical application of donor specific antibodies (DSAs) detected by a single antigen Luminex virtual crossmatch,and to discuss the treatment of DSA and the impact of DSA on renal function.Methods Serum from living-relative renal recipients before and after transplantation was investigated using a Luminex single antigen assay.The relation between DSA and renal acute rejection as well as renal function was analyzed.Results A total of 30 patients and 173 serum samples were tested,including 47 serum samples before transplantation,and 126 after transplantation.DSA was positive in one patient before transplantation,and 8 patients after transplantation.Three of the patients positive for DSA were treated by Bortezomib,3 by addition of MMF,2 by addition of CNI,1 by addition of Sirolimus.The MFI of DSA in one of the patients treated by Bortezomib was decreased to below 1000,while that in the other two decreased by more than 50 ％.The renal eGFR at the time with and without DSA was (1.50 ± 0.59) and (1.23 ± 0.38)ml/s respectively (P＜0.05).Conclusion Dynamic monitoring of single bead antigen antibody DSA conduces to direct the adjustment of immunosuppressant.The appearance of DSA contributes to the declination of renal function.Application of Bortezomib decreased the MFI of DSA.

ObjectiveTo investigate the short- and long-term effects of radiofrequency ablation (RA) versus minimally invasive hepatectomy (MIH) in the treatment of small hepatocellular carcinoma (SHCC). MethodsPubMed, Web of Science, Embase, Cochrane Library, CBM, CNKI, Wanfang Data, and VIP were searched for Chinese and English articles on RA versus MIH in the treatment of sHCC published up to August 2019. Quality assessment was performed for the articles included, and RevMan 5.1 was used for analysis. ResultsA total of 7 studies with 737 patients were included after screening, and there were 393 patients in RA group and 344 patients in MIH group. Compared with the MIH group, the RA group had significantly shorter time of operation (mean difference ［MD］=-206.57, 95% confidence interval ［CI］: -387.28 to -25.86, P=0.03) and length of hospital stay (MD=-4.02, 95%CI: -4.94 to -3.10, P＜001), as well as a significantly lower overall incidence rate of postoperative complications (odds ratio ［OR］=0.31, 95%CI: 0.20-047, P＜0.01). Compared with the RA group, the MIH group had significantly higher 3-year overall survival rate (OR=0.55, 95%CI: 0.36-0.84, P＜0.01), 1-year disease-free survival rate (OR=0.63, 95%CI: 0.41-0.98, P=0.04), and 3-year disease-free survival rate (OR=0.51, 95%CI: 0.34-0.74, P＜0.01), as well as a significantly lower local recurrence rate after surgery (OR=187, 95%CI: 1.31-2.68, P＜0.01). ConclusionIn the treatment of sHCC, RA has good short-term effect, good safety, and poor long-term effect, while MIH has good long-term effect and poor short-term effect.

Abstract According to the Healthy China Action Plan, Wuhan gives full play to the role of preventing and controlling student myopia by promoting student health. The primary focus is placed on education in schools, and Wuhan has integrated educational resources to develop a multi-level myopia prevention and control system and service network for school students. The network contains educational adminstrative, schools, families, and professional technical service organizations. By integrating multiple disciplines, Wuhan has built a comprehensive vision health management service system for all students. The Internet and cloud intelligent monitoring facilitated the establishment of a smart vision health management platform for students, which thoroughly and efficiently implemented myopia prevention and control to safeguard students visual health by engaging in education, monitoring, and supervision. The prevention and control of student myopia is a breakthrough for comprehensive healthy development of students. A comparison of the standard myopia rate in Wuhan in 2019 and 2018 revealed that the standard myopia rate at different learning stages of primary school, junior high school, and high school dropped by 3.31, 2.50, and 2.26 percentage points, respectively, and the rate of myopia in primary school was significantly lower than the national level. Post-epidemic surveys showed that the compliance rate and the awareness rate of the visual environment and visual behaviors of primary and secondary school students in Wuhan reached more than 80%, and prevalence of newly onset myopia or decreased vision was 30%, which was lower than the national average. The "Wuhan Model" provides an important referential framework for public health services for school students.
