ObjectiveTo analyze and evaluate the responsiveness and feasibility of the quality of life instrument for patients with systemic lupus erythematos(SLE).Methods143 cases of SLE patients were measured by QLICD-SLE before and after treatment and the data were analyzed with the traditional hypothesis test and combining the effect size,standardized response mean,the relative efficiency,the standard effect size and the feasibility analysis methods.Results(1)Paired t test before and after treatment indicated that there were significant differences between after treatment and before treatment in physical(t=2.39,P<0.05) and specific module domain(t=2.22,P<0.05),while there were no significant promotion in the scores of psychological function,social function and total score after treatment.There were no significant changes of SES,SRM and CR after treatment.(2)Most patients could understand the meaning of the instrument well and spent 15-20 minutes to finish it.The rate of recovery and completed were 98.0% and 97.8% respectively.ConclusionsThe QLICD-SLE can detect clinical change of treatment with good responsiveness and feasibility.

Objective To detect the expressions of angiotensin-receptor-1 (AT1R) and hypoxia-inducible factor (HIF)-1αin glomeruli and juxtaglomerular apparatus of different types of lupus nephritis (LN) patients, and analyze the correlation between them with systemic lupus erythematosus disease activity index (SLEDAI) complement 3, serum creatinine and 24-hour proteinuria in order to explore the role of the two factors in the pathogenesis of lupus nephritis (LN). Methods Between May 2010 and April 2016, a total of 90 patients with LN and 8 healthy controls were selected from Department of Rheumatology, Qujing Affiliated Hospital of Kunming Medical University and the First Affiliated Hospital of Kunming Medical University. The expressions of AT1R and HIF-1αin renal biopsy specimens were measured by streptavidin-perosidase (SP) of immunohistochemical stains. Pathological graphic analysis system was used for semi-quantitative estimate. Levels of SLEDAI, C3, serum creatinin and 24-hour proteinuria were also detected. Finally the relationshipbetween the two factors with clinical data was analyzed. The ANOVA test was used for intergroup comparison, and SNK-q test was used for the two groups comparison. Pearson's analysis was used for correlation analysis. Results The AT1R [(10.55 ±0.31)% vs (7.04 ±0.11)%] and HIF-1α [(10.51 ±0.52)% vs (8.96 ±0.31)%] in the glomeruli of typeⅠLN was significantly higher than healthy controls(all P<0.05). In the early phase of LN, RAS was activated and tissues were ischemic and hypoxic. The highest expression of AT1R (18.22 ± 2.11)% and HIF-1α (19.48 ±0.61)% in glomeruli was found in type Ⅳ LN, especially in juxtaglomerular apparatus, AT1R (19.98 ±0.21)% and HIF-1α(24.90 ±0.70)%. AT1R was positively correlated with HIF-1αin the glomer-ulus (r=0.949, P<0.01) and juxtaglomerular apparatus (r=0.762, P<0.05). AT1R and HIF-1αin juxtaglomerular apparatus was positively correlated with 24-hour proteinuria (r=0.756, P<0.05 and r=0.802, P<0.05). Conclusion High expressions of AT1R and HIF-1α have been shown in active LN biopsies. It proves that RAS is activated by ischemia and hypoxia, then it up-regulates HIF-1α expression. Our results suggest that the two factors may be associated with disease activity of LN.

Objective:To explore the epidemiologic characteristics of long-lived population and influencing factors in Shanglin county of Guangxi and provide scientific basis for the study of health and longevity in Guangxi.Methods:We collected and analyzed the general demographic cross-sectional data of the long-lived individuals (≥90 years old) in 11 villages and towns by multi-source registration and face-to-face interview. The age group control design was adopted to conduct a comparison among the longevity group (90-100 years old), centenarian group (≥100 years old), the longevity plus centenarian group and control group (local population aged 40-85 years), and identify the factors related to longevity.Results:Among the 496 007 people registered in Shanglin, 1 533 were aged ≥90 years, including 1 453 in the longevity group, with an average age of (92.84±2.46) years, and 80 in the centenarian group, with an average age of (102.67±2.60) years. The spatial distribution of long-lived individuals and centenarians was mainly in the north and central areas, and sparse in southwest area. Analysis on factors related to health and longevity indicated that old people with Zhuang ethnic ( OR=1.551,95% CI:1.308-1.838), married ( OR=55.507,95% CI:36.087-85.377) and moderately high waist-to-hip ratio ( OR=258.056,95% CI:27.775-2 397.569), and SBP ( OR=1.019,95% CI:1.013-1.026) tended to live longer. Conclusions:We found that the rate of longevity in Shanglin was higher than the average level in Guangxi and China. Longevity in Shanglin country had unique spatial and population distribution characterics of female longevity more than male longevity, mainly Zhuang ethnic and so on. Being women, married, family history of longevity, appropriate high waist-to-hip ratio, SBP and blood sugar level might be positive factors for longevity in Shanglin, but the impacts of other factors on longevity need further study.

Objective:To investigate the epidemiological characteristics and relevant factors among individuals characterized by their longevity in multiple regions of Guangxi Zhuang Autonomous Region, and provide a valuable scientific perspective for the research in health and longevity of the elderly in Guangxi.Methods:Registration and face-to-face questionnaire on a door-to-door basis were adopted to collect the demographic characteristics of the long-lived individuals (≥90 years old) in Bama of Hechi city, Yongfu of Guilin city, Dongxing of Fangchenggang city, Guangxi. Then, among the local general population, individuals within the age group between 40 and 85 years old were selected randomly as controls. Correlations were then analyzed between the relative health and longevity of the subjects and their gender, ethnicity, family history, disease history, marital status, the number of family generations, the number of children, smoking, drinking, outdoor activities, sleep and other health-related factors, then the result was subject to further analysis by comparing the long-lived population and the control population respectively.Results:Among 691 500 of the permanent residents of Bama, Yongfu and Dongxing city, 1 005 cases were 90 years old and over with a ratio of 145.34 out of 100 000 persons; within the 1 005 cases, 944 were aged between 90 and 100 (longevity rate: 136.51/100 000) with an average age of (93.28±2.57); 61 cases were aged 100 or over, arriving at a centenarian rate of 8.82/100 000 with an average age of (102.00±3.05) years. Significant differences were found just among three particular factors — regional distribution ( P=0.014), history of disease ( P=0.002), four generations of family ( P=0.008) between nonagenarians and centenarians ( P<0.05), while the other 15 indicators did not show anything noteworthy. The result indicated that longevity and centenarians might be the same group and then we combined both groups into one. By cross-comparison between the longevity-plus- centenarians and the control group in the region, factors listed below exhibited significant correlation with health and longevity: marital status ( OR=26.469, 95% CI: 13.208-53.045), number of generations within the family ( OR=5.419, 95% CI: 3.418-8.592), number of male offspring ( OR=2.013, 95% CI: 1.555-2.607), number of female offspring ( OR=1.380, 95% CI: 1.122-1.696), and the frequency of outdoor activities ( OR=10.226, 95% CI: 3.164-33.045). Conclusions:The longevity rate is higher in the general natural population in Bama, Yongfu and Dongxing of Guangxi. The phenomenon may owe to favorable family structure, atmosphere within or out of the family or other elements related with social surrounding. Among them all, mentality, inclination to physical exercise and regular rhythm of life may all exert tremendous contributory influence here.
