Study of hot spring bathing and chronic disease prevalence among residents between 30 and 65 in typical hot spring areas of Guizhou Province / 上海预防医学

Objective To investigate hot spring bathing behavior and chronic disease prevalence of residents aged 30 to 65 in typical hot spring areas of Guizhou Province. Methods Totally 3 708 individuals between 30 and 65 in five typical hot spring areas of Guizhou Province were included in this study. Their hot spring bathing behavior and chronic disease prevalence were recorded. Unconditional logistic regression was used to analyze the association between hot spring bathing and the incidence of chronic diseases. Results 71.3% of the residents in the hot spring areas had bathed in hot springs, with the proportion higher in males than females(χ2=92.856, P < 0.001). 76.3% of people took hot spring baths fewer than or equal to 6 times per year, 30.8% of residents often chose to take hot spring baths in the evening, and 37.6% of the residents took hot spring baths for 21-40 minutes. Bathing was more common in winter. 11.5% and 17.9% of the residents added other substances and used hot spring facilities, and most of them added traditional Chinese medicine and used the sauna. 46.6% and 41.6 % of the residents took hot spring baths to relax and relieve fatigue. The self-reported prevalence rate of chronic diseases was 522.1‰, and the top five single diseases were lumbar intervertebral disc disease(119.7‰), hypertension(118.1‰), urinary calculus(77.7‰), cervical intervertebral disc disease(53.7‰)and osteogenesis(44.5‰). Compared with those who never bathed in hot springs, taking hot spring baths 7-11 times a year was negatively correlated with chronic diseases.(OR=0.551, 95%CI: 0.345-0.879). Conclusion Hot spring bathing is popular in typical hot spring areas of Guizhou Province, but its frequency is not high. The overall prevalence of chronic diseases is relatively high, and the order of most prevalent chronic diseases is different from that in other areas. Proper hot spring bathing is negatively correlated with chronic diseases.

Association between hot spring bathing and quality of life of smokers in typical hot spring areas of Guizhou Province / 上海预防医学

Objective To analyze the association between hot spring bathing and the quality of life of smokers living in typical hot spring areas of Guizhou to make suggestions on improving their quality of life. Methods The study is a cross-sectional study whose data was collected by questionnaires. The WHO Quality of Life Scale(WHO QOL-BREEF)was used to measure quality of life. Results The quality of life in the psychological domain(14.09±1.83 vs 13.79±1.82, P < 0.05)and the environmental domain(12.70±1.84 vs 12.37±1.67, P < 0.05)among smokers who took hot spring baths was significantly higher than that among those who did not. After adopting ordinary logistic regression model to adjust for other factors, for the physical domain, the odd of scoring"good"in the WHO scale in group of smokers who took hot spring baths less that once a month was 0.70 lower than that in those who took baths at least once a month(OR=0.70, 95%CI: 0.54-0.91). In psychological domain, the odd of the group of smokers who did not take hot spring baths was 0.65 lower than that in those who took baths at least once a month(OR=0.65, 95%CI: 0.47-0.90). And the odd of the group of smokers who bathed less than once in a month was 0.71 lower than those who bathed at least once a month(OR=0.71, 95%CI: 0.54-0.92). Conclusion There is a positive relationship between hot spring bathing and quality of life, which prompts that people who smoke take hot spring baths to improve their quality of life.

Association between hot spring bathing behavior and hypertension and the mediating effect of sleep quality problems in typical hot spring areas of Guizhou Province / 上海预防医学

Objective To investigate the association between hot spring bathing behavior and hypertension and understand the mediation effect of sleep quality problems on the association. Methods A cross-sectional survey was conducted among adults aged 30 to 65 living and working around five hot springs in Guizhou Province, employing a self-designed questionnaire on the health status and hot spring bathing, and 3 708 qualified questionnaires were collected. Participants were divided into three groups according to their frequency of hot spring bathing: never, occasionally, and frequently. Stratified via sex and sleep quality, the binary logistic regression model was used to analyze the association between different hot spring bathing frequencies and self-reported hypertension. Results Significant difference was detected in the self-reported hypertension between groups who never bathe(13.7%), who occasional bathe(9.4%)and who frequently bathe(8.5%)among female participants(χ2=10.460, P=0.005). However, no significant difference was found among different bathing groups in males. Furthermore, multivariate analysis showed that compared with no bathing, occasional(OR=0.692)and frequent (OR=0.594)hot spring bathing were associated with lower hypertension prevalence among female population, and female groups of occasional and frequent bathing with sleep quality problems had smaller OR(OR=0.571 and 0.406, respectively). After sleep quality problems were included, hot spring bathing was still associated with lower hypertension risk, and the OR values of occasional bathing and frequent bathing groups were 0.723 and 0.611, respectively. The sleep quality problems of female population played a partial mediating role in the association between hot spring bathing and hypertension, and the relative mediating effects of occasional bathing and frequent bathing with hypertension were both statistically significant(Zm=-2.022 and -1.995, P < 0.05), which accounted for 34.34% and 30.15% of the total effects, respectively. Conclusion Regular hot spring bathing may play an auxiliary role in the prevention of hypertension, and it may provide a stronger protection for women, and especially those with sleep quality problems. Sleep quality problems may explain part of the association between hot spring bathing and hypertension in female population.

Prevalence of osteoarthrosis and its association with hot spring bathing among local adults in typical hot spring areas of Guizhou Province / 上海预防医学

Objective To investigate the prevalence of osteoarthrosis and the association between hot spring bathing and osteoarthrosis among local adults in typical hot spring areas of Guizhou Province. Methods A face-to-face questionnaire survey was conducted among residents aged from 30 to 65 in five typical hot spring areas, including Xifeng(Xifeng County, Guiyang), Jianhe(Jianhe County, Qiandongnan), Fodingshan(Shiqian County, Tongren), Guiyu(Wudang District, Guiyang)and Huishangu(Suiyang County, Zunyi). Residents' basic information, bone and joint diseases prevalence, hot spring bathing, and other health-related behaviors were investigated in this study. The prevalence of local bone and joint diseases was analyzed, and binary logistic regression was used to calculate OR(95%CI)to analyze the association between hot spring bathing and bone and joint diseases. Results A total of 3 708 adults(1 648 males and 2 060 females)were included as the statistical analysis survey subjects, and 794 people reported bone and joint diseases, accounting for a prevalence rate of 21.41%, 95% CI: 0.201-0.227. The prevalence of females(24.56%)was higher than that of males(17.48%)(P < 0.001). The prevalence rates of diseases increased with age(χtrend2=130.265, P < 0.001). There were also statistically significant differences in the prevalence rate of bone and joint diseases among different genders, age groups, occupations, education levels, and smoking behaviors(P < 0.05). After gender, age, occupation, education and smoking were adjusted for, compared with the group who never took hot spring baths, participants who took hot spring baths occasionally(OR=0.793, 95%CI: 0.631-0.996)and frequently(OR=0.713, 95%CI: 0.536-0.948)were associated with a lower risk of bone and joint diseases. Conclusion The prevalence of osteoarthrosis is 21.41% in the typical hot spring areas of Guizhou Province. Older or females have a higher risk of prevalence of bone and joint diseases. Hot spring bathing may be associated with a lower risk of bone and joint diseases.

Current status and influencing factors of osteoporosis risk among residents in typical hot spring areas in Guizhou Province / 上海预防医学

Objective To understand the current status of osteoporosis risk and influencing factors for residents from 30 to 65 years old in typical hot spring areas in Guizhou province, and to provide a theoretical basis for reducing the risk of osteoporosis and the prevention of osteoporosis in the population. Methods A health questionnaire for residents in typical hot spring areas in Guizhou, osteoporosis risk test questions, Pittsburgh sleep quality index(PSQI), etc were used. A face-to-face survey of 3 708 residents was conducted, and logistic regression was used to analyze the influencing factors of osteoporosis risk in hot spring areas. Results 2 403(64.81%)residents of 3 708 people surveyed were at risk of osteoporosis, of whom 1 434(87.4%)males and 969 females(47.1%)had a higher risk of osteoporosis (χ2=652.4, P < 0.001). As age increased, more residents were at risk of osteoporosis(χ2=273.4, P < 0.001), and numbers of residents of 30-39 years old, 40-59 years old, and above 60 years of age at risk of osteoporosis were 319(49.2%), 1 572(62.9%), and 512(93.6%). Male osteoporosis risk was negatively correlated with an education level of undergraduate and above(OR=0.37, 95%CI: 0.19-0.73). Age 40-59(OR=1.54, 95%CI: 1.07-2.22), 60 and above(OR=6.39, 95%CI: 2.76-14.79), and sleep disorders(OR=1.59, 95%CI: 1.08-2.35)may increase the risk of osteoporosis in male residents in hot spring areas. Less oil in daily diet may increase the risk of osteoporosis in women(OR=1.70, 95%CI: 1.23-2.36). Age 40-59(OR=1.54, 95%CI: 1.17-2.03), over 60 and above(OR=16.24, 95%CI: 10.10-26.12), and sleep disorders(OR=1.84, 95%CI: 1.48-2.28)were positively correlated with risk of osteoporosis in women. Women with junior high school degree(OR=0.61, 95%CI: 0.47-0.80), high school degree(OR=0.57, 95%CI: 0.37-0.89)and undergraduate degree and above(OR=0.59, 95%CI: 0.39-0.98)had a lower risk of osteoporosis than women who were illiterate or semi-illiterate. The osteoporosis risk test questions showed that smoking, heavy drinking, and erectile dysfunction and reduced sexual desire were the main sources of osteoporosis risk in men. Menopause before the age of 60, ≤45 years old, no milk and no calcium supplements, parents with osteoporosis or bone fractures were the major risk sources of osteoporosis in women. Conclusion The risk of osteoporosis among male residents from 30 to 65 years old in typical hot spring areas in Guizhou province is higher than that among women. Education of osteoporosis prevention should be strengthened among local residents to promote healthy behaviors and lifestyles.

@#Objective To investigate the expression of long non－coding ＲNA SFTA1P in non small cell lung cancer ( NSCLC) and its biological function in NSCLC cell lines． Methods Quantitative real time polymerase chain reaction( qＲT－PCＲ) was used to detect the expression of SFTA1P in 18 pairs of NSCLC tissues and adjacent normal tissues． The expression of SFTA1P was detected by qＲT－PCＲ in five different NSCLC cell lines ( A549，SPCA1，H460，H1975 and H1299) and one normal lung epithelial cell line ( HBE) ． The overexpression vector of SFTA1P was designed and constructed． The overex- pressed cell line was constructed by transfection，the effects of overexpression of SFTA1P on proliferation， invasion and migration of NSCLC cells were detected by CCK－8 assay and transwell assay． Ｒesults The expression of SFTA1P in NSCLC tissues was lower than that of adjacent normal tissues ( t = 2. 158，P = 0. 043) ． SFTA1P expression was detected in 5 strains of NSCLC cell lines and normal lung epithelial cell line． The expression of SFTA1P was the lowest in A549 and H460 cell lines ( t = 5. 769，P = 0. 004; t = 5. 772，P= 0. 004) ，and the highest in H1299 and H1975 cell lines ( t = 22. 248，P＜0. 001; t = 11. 814，P ＜0. 001) ． SFTA1P overexpression cell models were successfully constructed using A549 and H460 cell lines( all P＜0．05) ． The overexpression of SFTA1P could inhibit proliferation，invasion and migration of H460 and A549 cells ( ( all P ＜ 0． 05) ． Conclusions SFTA1P can affect the biological functions of NSCLC cells by inhibiting the proliferation，migration and invasion． SFTA1P may play a role as a tumor suppressor gene in tumorigenesis and development．

A study on epidemic model of hepatitis B virus in migrant workes in Guizhou minority areas / 中华疾病控制杂志

Objective To research the prevalence model of hepatitis B virus in the minority areas of Guizhou and to provide reference for the prevention and control virus of hepatitis B virus. Methods Using multi-stage cluster simple random sampling, four villages were selected from Leishan and Libo counties in minority areas of Guizhou. Questionnaires were investigated by trained investigators and serum hepatitis B virus five-item test results were collected from the subjects. Results A total of 1 629 participants were surveyed, the outcome showed that migrant workers’ infection rate of hepatitis B was 44.8%, and the carrying rate of HBsAg was 8.4%. The positive rates of anti-HBs and anti-HBc were 28.0% and 25.6% respectively. The infection model rate of migrant workers was 19.8%, which was lower than that of non-migrant workers (23.2%) (P>0.05).The detection rate of susceptible model in migrant workers (52.2%) was higher than that in non-migrant workers (43.4%), while the detection rate of immune mode migrant workers (28.0%) was lower than that in non-migrant workers (33.4%),which the difference was statistically significant (all P<0.05). After adjusted related factors by multivariate Logistic regression analysis model, migrant workers were still the influencing factors of vulnerability model (OR=1.568, 95% CI:1.206-2.039) compared with non-migrant workers. Conclusion There was a high susceptibility to hepatitis B virus among migrant workers in minority areas of Guizhou, In order to reduce the infection and prevalence of hepatitis B virus, we should strengthen the immunization of hepatitis B vaccine to migrant workers and to improve their specific immunity.

Correlation of 1-year vision outcomes with baseline factors in polypoidal choroidal vasculopathy patients after anti-VEGF treatment / 眼科新进展

Objective To analyze the correlation between baseline factors and the best corrected visual acuity (BCVA) after 3 monthly anti-vescular endothelial growth factor (VEGF) therapy in naive polypoidal choroidal vasculopathy (PCV).Methods This was a retrospective cohort study in 44 naive PCV patients (44 eyes) treated in our hospital between July 2015 and December 2016,and BCVA,optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) + indocyanine green angiography (ICGA) examinations were performed at first.All patients were treated with monthly antiVEGF (including ranibizumab and conbercept) injections for 3 consecutive months,followed by the needed retreatment,and BCVA at the 12th month during follow-up after the first anti-VEGF treatment was recorded,following the comparison with baseline BCVA,and then the patients were divided into improved and unimproved groups according to BCVA changes.Finally,univariate and logistic regression analysis were used to analyze the correlation between the baseline factors and BCVA.Results The univariate analysis showed that the improved group had shorter onset time,smaller greatest linear dimension (P =0.045 and 0.037,respectively).Logistic regression showed the difference in choroidal vascular hyperpermeability and greatest linear dimension was statistically significant,suggesting that they were the independent predictors of visual outcome (regression coefficient =0.963 and 0.001,P =0.010 and 0.012,odds ratios =0.083 and 1.002,95％ confidence interval =0.013-0.549 and 1.001-1.004,respectively).Conclusion Choroidal vascular hyperpermeability may be a predictor for poor visual acuity prognosis in PCV patients after anti-VEGF,and greatest linear dimension and the time of onset are also related to postoperative visual acuity in PCV patients after anti-VEGF.

Awareness of Age-related Macular Degeneration and Its Risk Factors among Beijing Residents in China / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Age-related macular degeneration (AMD) is a major cause of irreversible blindness, and awareness of this disease is important in the prevention of blindness. However, lack of public awareness of AMD was shown in previous studies, and there was no report of AMD awareness in the Mainland of China. Therefore, the aim of our study was to assess the awareness of AMD and its risk factors among Beijing residents in China.</p><p><b>METHODS</b>A cross-sectional, computer-assisted, telephone investigation was conducted to measure the awareness of AMD among Beijing residents. All the contacts of potential respondents were randomly generated by computer. Only those above 18 years of age and willing to participate in the study were included. The questionnaire for the study was modified from the AMD Alliance International Global Report. Pearson's Chi-square test and binary logistic regression analysis were used to identify the factors that affected the knowledge of AMD.</p><p><b>RESULTS</b>Among 385 Beijing residents who agreed to participate, the awareness of AMD was 6.8%, far below than that of cataract and glaucoma. Participants who were above 30 years of age (odds ratio [OR] 6.17, confidence interval [CI] 1.44-26.57), with experience of health-related work (OR 8.11, CI 3.25-20.27), and whose relatives/friends or themselves suffering from AMD (OR 32.18, CI 11.29-91.68) had better AMD awareness. Among those familiar with AMD, only 35% of them identified smoking as a risk factor, and only 23.1% of the residents believed that smoking could lead to blindness.</p><p><b>CONCLUSIONS</b>The sample of Chinese population had limited knowledge of AMD. Educational programs need to be carried out to raise public awareness of AMD.</p>

Evaluation of effects of self-treatment on patients with Keshan disease by echocardiography / 中国地方病学杂志

Objective To observe the change in cardiac shape and heart function and evaluate the effect of self-treatment on patients with Keshan disease by echocardiography. Methods To check the 31 patients with Keshan disease before the self-treatment, and follow them up in the 3rd and 6th months after self-treatment by echocardiography. The left atrium diameter(LAd), left ventricular end-diastolic diameter(LVEDd), the thickness of interventricular septum in end-diastolic(IVSTd), the thickness of LV posterior wall in end-diastolic (LVPWTd), left ventricular mass(LVM), left ventricular mass index(LVMI), left ventricular ejection fraction(LVEF) and mitral valve flow E/A ratio(E/A) were measured. Results The LAd[(35.8±5.1)ram] and LVPWTd[(9.3±1.0)mm] obviously decreased in the 3rd month after serf-treatment compared with prior self-treatment [ (37.0±5.0), (9.9± 1.2)mm](P<0.05). The LAd[(34.5±5.0)mini, IVSTd[(9.5±1.3)mm], LVEDd[(50.2±7.7)mm], LVPWTd [(8.7±1.1)mm], LVM[(196.1±87.2)g] and LVMl[(126.5±56.4)g/m2] obviously decreased in the 6th month after self-treatment compared with prior self-treatment [(37.0±5.0), (10.2±1.5), (51.3±8.1), (9.9±1.2)mm, (230.4±95.5)g, (144.0±54.6)g/m2] and in the 3rd month after self-treatment [(35.8±5.1)mm, (10.2±1.4) ram, (51.1±8.1)nun, (9.3±1.0)mm, (219.4±82.5)g, (136.8±50.0)g/m2] (P<0.05). The results of the mitral valve flow E/A ratio and LVEF in the 3nt month after self-treatment [1.0±0.5, (59.4±13.3)%] were increased compared with the prior self-treatment[0.9±0.5, (58.1±15.6)%], and the results in the 6th month after self-treat- ment[ 1.0±0.4, (60.7±13.6)%] were further inereased compared with before, but there was no signifieant differ- ence(P0.05). Conclusions Self-treatment of Keshan disease patients can improve the heart function by pre- venting left ventrieular remodeling and reversing. Echocardiography can be used as an essential technique to evalu- ate the effect of self-treatment on Keshan disease patients.
