Objective: To investigate the prevalence and influencing factors of chronic diseases among adult residents in Hunan Province, so as to provide insights into management of chronic diseases. Methods: Permanent residents at ages of 18 years and older were sampled using a multi-stage random sampling method in Hunan Province from April to June, 2021, and participants' demographics, smoking, alcohol consumption, sleep quality and development of chronic diseases were collected using questionnaire surveys. The prevalence of chronic diseases was estimated and standardized by the seventh national population census data. In addition, the factors affecting the prevalence of chronic diseases were identified using a multivariable logistic regression model. Results: A total of qualified 9 469 adult residents were enrolled, including 4 678 men (49.40%) and 4 791 women (50.60%), with a mean age of (59.37±14.14) years. The overall prevalence and standardized prevalence rates of chronic diseases were 50.84% and 38.44%, respectively, and the prevalence and standardized prevalence rates of hypertension, protrusion of intervertebral disc and diabetes were 18.66% and 15.06%, 6.31% and 5.28%, and 4.44% and 4.18%, respectively. Multivariable logistic regression analysis revealed that women (OR=1.252, 95%CI: 1.131-1.386), age (45 years-, OR=3.699, 95%CI: 3.104-4.407; 60 years and older, OR=9.255, 95%CI: 7.743-11.064), unmarried/divorced/widowed (OR=1.170, 95%CI: 1.036-1.321), educational level (junior high school, OR=0.730, 95%CI: 0.653-0.816; high school/technical secondary school, OR=0.710, 95%CI: 0.609-0.827; diploma and above, OR=0.586, 95%CI: 0.454-0.758), monthly household income (3 000 yuan-, OR=0.846, 95%CI: 0.759-0.943; 6 000 yuan-, OR=0.819, 95%CI: 0.710-0.943; 10 000 yuan and higher, OR=0.790, 95%CI: 0.657-0.950), smoking (OR=1.528, 95%CI: 1.363-1.713), insomnia (OR=2.637, 95%CI: 2.271-3.063) statistically correlated with the development of chronic diseases. Conclusion The prevalence of chronic diseases was 50.84% among adult residents in Hunan Province in 2021, and hypertension was the predominant chronic disease. Women, the middle-aged and elderly residents, residents with a low educational level and residents with low incomes are at a high risk of developing chronic diseases.

Purpose: This study aimed to determine the level of health-related quality of life (HRQoL) of children and adolescents who received hematopoietic stem cell transplantation (HSCT) and to examine factors influencing HRQoL. Methods: This cross-sectional descriptive study involved 85 participants aged 10 to 19 years who received treatment from 3 months to 5 years after HSCT. Symptom experiences, stress and coping, self-esteem, social support, and HRQoL were measured. Descriptive analysis, the independent t-test, one-way analysis of variance, Pearson correlation analysis, and stepwise multiple regression were used for data analysis. Results: The mean HRQoL score was 72.26 points out of 100. HRQoL showed statistically significant correlations with symptom experiences, stress, self-esteem, social support, satisfaction with peer relationships, and perceived attentiveness of the medical team. The most influential predictors of HRQoL were symptom experiences (β=-.51, p<.001) and satisfaction with peer relationships (β=.32, p<.001). Conclusion The experiences of different symptoms by children and adolescents who receive HSCT must be considered. In addition, nursing interventions, such as self-help meetings with peer groups, should be provided to improve their HRQoL.

Using the isolated total RNA from osteosacoma cell line MG63, the cDNA encoding human OPG was amplified by RT-PCR. A recombinant adenoviral vector carrying cDNA of OPG was constructed and OPG expression in mouse myoblast C2C12 cells was confirmed by Western blot and ELISA. The secreted expression of OPG protein persisted more than 6 weeks in vitro, and the growth of C2C12 cells infected by recombinant adenoviral were in good state. Osteoclasts derived from mouse bone marrow cells infected with recombinant adenoviral made less number of TRAP positive cells and resorption pits formed on dentine slices.

This study was designed to investigate the different involvements of prostatic stromal cells from the normal transitional zone (TZ) or peripheral zone (PZ) in the carcinogenesis of prostate cancer (PCa) epithelial cells (PC-3) in vitro and in vivo co-culture models. Ultra-structures and gene expression profiles of primary cultures of human prostatic stromal cells from the normal TZ or PZ were analyzed by electron microscopy and microarray analysis. In vitro and in vivo co-culture models composed of normal TZ or PZ stromal cells and human PCa PC-3 cells were established. We assessed tumor growth and weight in the in vivo nude mice model. There are morphological and ultra-structural differences in stromal cells from TZ and PZ of the normal prostate. In all, 514 differentially expressed genes were selected by microarray analysis; 483 genes were more highly expressed in stromal cells from TZ and 31 were more highly expressed in those from PZ. Co-culture with PZ stromal cells and transforming growth factor-beta1 (TGF-beta1) increased the tumor growth of PC-3 cells in vitro and in vivo, as well as Bcl-2 expression. On the other hand, stromal cells of TZ suppressed PC-3 cell tumor growth in the mouse model. We conclude that ultra-structures and gene expression differ between the stromal cells from TZ or PZ of the normal prostate, and stroma-epithelium interactions from TZ or PZ might be responsible for the distinct zonal localization of prostate tumor formation.

OBJECTIVETo explore the influence of methylprednisolone (MP) on cellular component in donor graft and on H-2 haploidentical hematopoietic stem cell transplantation (HSCT) in mice.

METHODSA murine model of H-2 haploidentical HSCT was established by using of c57BL/6J male mouse as donor and (c57BL/6J x LB/C) F1 female mouse as recipient. The donor mouse received peripheral-blood (PB) progenitor cells mobilization regimens consisted of recombinant human granulocyte colony-stimulating factor (rhGCSF) alone (control group) or combined with MP in dose of 2 mg/kg daily [small-dose (SD) group], 10 mg/kg daily [middle-dose (MD) group], and 50 mg/kg daily [large-dose (LD) group] respectively. Percentage of T cell subsets, DC1 (HLA-DR+CD11c+) and CD34+ cell in the grafts were detected by flow cytometry. Transplant rejection,severity of GVHD and survival time were observed.

RESULTSThe percentages of CD3+ T cell in donor grafts in the three groups were significantly lower than that in control group (P < 0.05). The percentage of CD3+ CD4+ T cells decreased more significantly than that of CD3+ CD8+ T cells, and CD4/CD8 ratios decreased significantly. The percentage of CD4+ CD25+ T cells increased significantly, the percentage of DC1( HLA-DR+CD11c+) decreased and the percentage of CD34+ cells increased in all the three groups than in control group. There were significant differences in the percentage of CD3+ T cells, CD3+ CD4+ T cells and CD34+ cells in donor grafts among SD group, MD group and LD group (P < 0.05). The engraftment rates in control, SD, MD and LD groups were 90%, 100%, 100% and 80% respectively. Severity of aGVHD in each study group decreased significantly compared with that in control group (P < 0.05). There were statistical differences among different dosage groups (P < 0.05). Survival time after transplantation in all study groups were significantly longer than that in control group (P < 0.05), and in MD group was significantly longer than in SD group and LD groups (P < 0.05).

CONCLUSIONSAddition of methylprednisolone to routine donor mice HSC mobilization regimen has a definite effect in alleviating aGVHD and prolonging survival time of mouse after H-2 haploidentical HSCT. With a suitable dosage addition of methylprednisolone to donor mice HSC mobilization regimen could avoid the increasing risk of graft rejection.

BACKGROUND AND OBJECTIVES: Hearing outcomes and prognostic factors of idiopathic sudden sensorineural hearing loss (SSNHL) were investigated in patients who underwent combined intratympanic and systemic steroid therapy. SUBJECTS AND METHOD: This study was performed by retrospective chart review. Clinical outcomes and prognostic factors were evaluated in 147 patients who received intratympanic steroid plus systemic steroid therapy. RESULTS: Complete hearing recovery was achieved in 36.7% (n=54) of the patients, partial recovery in 12.9% (n=19), slight recovery in 12.3% (n=18), and total recovery in 61.9% (n=91). Age was identified as an independent, negative prognostic factor for hearing recovery. The recovery rates of the down sloping and profound types were poorer than those of the up sloping type as determined by audiography. CONCLUSION: The results of this study suggest that the combined treatment of intratympanic and systemic steroids for idiopathic SSNHL results in high hearing recovery rates, and that the down-sloping and profound types of audiogram patterns and age are negative prognostic factors.
