ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

OBJECTIVE@#To compare the differences in the clinical effect on post-stroke hand spasm among the combined treatment of penetrating acupuncture and kinesiotherapy, the simple application of penetrating acupuncture and the simple application of kinesiotherapy.@*METHODS@#A total of 105 patients with post-stroke hand spasm were randomized into a penetrating acupuncture group, a kinesiotherapy group and a combined treatment group, 35 cases in each one, of which, 2 cases were dropped out in either the combined treatment group and the penetrating acupuncture group, and 1 case dropped out in the kinesiotherapy group. The routine rehabilitation training, e.g. occupational therapy and Bobath exercise and medication were adopted in all of the three groups. In the penetrating acupuncture group, the penetrating needling technique was exerted from Hegu (LI 4) to Houxi (SI 3) and from Waiguan (TE 5) to Sidu (TE 9) on the affected side. In the kinesiotherapy group, the persistent movement or passive movement was exerted on the wrist joint, the metacarpophalangeal joints and the interphalangeal joints. In the combined treatment group, the penetrating acupuncture (the same as the penetrating acupuncture group) was exerted combined with kinesiotherapy (the same as the kinesiotherapy group). In each group, the treatment was given once a day, 30 min in each time, 6 treatments a week in total, with the interval of 1 day between the courses. The treatment for 2 weeks was as one course and 2 courses were required totally. Before and after treatment, the scores of hand spasm index, hand-wrist motor function and the activity of daily living (ADL) were compared in each group.@*RESULTS@#After treatment, the scores of hand spasm index were reduced as compared with those before treatment in each group (0.05).@*CONCLUSION@#Compared with the simple application of either penetrating acupuncture or kinesiotherapy, the combined treatment of them achieves the significant improvements in hand spasm degree, hand wrist motor function and ADL in patients with stroke.

ABSTRACT

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.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of Echinococcus multilocularis on host liver cell proliferation in vivo using a BALB/c mouse alveolar hydatid infection model.</p><p><b>METHODS</b>Sixty-five 8-10-week-old female BALB/c mice were randomly divided into an experimental group (n = 40) and a control group (n = 25) and administered an abdominal injection into the left liver lobe of E. multilocularis protoscolices in saline solution or saline solution alone, respectively. At post-injection day 2, 8, 30, 60, and 90, liver samples were collected for analysis of lesions and lesion-adjacent tissue by hematoxylin-eosin staining and differential expression of proliferating cell nuclear antigen (PCNA), cyclin D1, cyclin A, and cyclin B1 by immunohistochemical staining. The significance of intergroup differences was assessed by Student's t-test.</p><p><b>RESULTS</b>The control group showed normal liver histology at all time points. The experimental group developed E. multilocularis lesions that showed increased severity of pathological features, such as inflammatory cell invasion, steatosis and fibrous connective tissue hyperplasia, over time. At post-injection days 2 and 8, enlarged, binuclear and apocyte hepatocytes were observed close to the lesions. At post-injection days 30, 60, and 90, the number of hepatocytes expressing PCNA progressively increased in the experimental group, and the numbers were significantly higher than in the control group (7.01 +/- 1.89 vs. 1.03 +/- 0.52, 8.41 +/- 2.80 vs. 0.93 +/- 0.31, and 13.4 +/- 4.43 vs. 1.07 +/- 0.94; all P < 0.05). The same progressively increasing trend was seen in the number of hepatocytes expressing CyclinD1, but was only significantly different from controls at post-injection days 30 and 60 (6.73 +/- 2.52 vs. 0.48 +/- 0.43 and 8.22 +/- 3.09 vs. 0.55 +/- 0.34; both P < 0.05). In contrast, the number of hepatocytes expressing cyclin A was significantly increased at post-injection day 30 and then showed a decreasing trend at days 60 and 90, although the numbers of expressing cells remained significantly higher than control levels at all time points (7.75 +/- 3.05 vs. 0.69 +/- 0.36, 3.42 +/- 1.80 vs. 1.14 +/- 0.42, and 3.03 +/- 1.50 vs. 0.69 +/- 0.31; all P < 0.05). The number of hepatocytes expressing CyclinB1 in the experimental group was less robust than the other cyclins (with a general temporal trend of increase followed by decrease), but the differential expression was not significantly different from the control levels at any time point.</p><p><b>CONCLUSION</b>E. multilocularis infection may promote the expression of host factors related to proliferation and anti-apoptosis in liver. This pathogen-mediated modulation of host cell-survival mechanisms may provide a rationale explanation for the clinical observations of hepatomegaly and the unexpected survival of alveolar echinococcosis patients following major hepatic resection.</p>

ABSTRACT

<p><b>BACKGROUND</b>Cystic echinococcosis due to Echinococcus granulosus (E. granulosus) is one of the most important chronic helminthic diseases, especially in sheep/cattle-raising regions. The larval stage of the parasite forms a cyst that grows in the liver, lung, or other organs of the host. To ensure a long life in the host tissues, the parasite establishes complex inter-cellular communication systems between its host to allow its differentiation toward each larval stage. Recent studies have reported that this communication is associated with the extracellular signal-regulated kinase (ERK) mitogen-activated protein kinase cascade in helminth parasites, and in particular that these protein kinases might serve as effective targets for a novel chemotherapy for cystic echinococcosis. The aim of the present study investigated the biological function of a novel ERK ortholog from E. granulosus, EgERK.</p><p><b>METHODS</b>DNA encoding EgERK was isolated from protoscolices of E. granulosus and analyzed using the LA Taq polymerase chain reaction (PCR) approach and bioinformatics. Reverse transcription PCR (RT-PCR) was used to determine the transcription level of the gene at two different larval tissues. Western blotting was used to detect levels of EgERK protein. The expression profile of EgERK in protoscolices was examined by immunofluorescence.</p><p><b>RESULTS</b>We cloned the entire Egerk genomic locus from E. granulosus. In addition, two alternatively spliced transcripts of Egerk, Egerk-A, and Egerk-B were identified. Egerk-A was found to constitutively expressed at the transcriptional and protein levels in two different larval tissues (cyst membranes and protoscolices). Egerk-A was expressed in the tegumental structures, hooklets, and suckers and in the tissue surrounding the rostellum of E. granulosus protoscolices.</p><p><b>CONCLUSIONS</b>We have cloned the genomic DNA of a novel ERK ortholog from E. granulosus, EgERK (GenBank ID HQ585923), and found that it is constitutively expressed in cyst membrane and protoscolex. These findings will be useful in further study of the biological functions of the gene in the growth and development of Echinococcus and will contribute to research on novel anti-echinococcosis drug targets.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect on the motor function of stroke patients by combination of needling at Back-shu point and trunk exercise.</p><p><b>METHODS</b>Ninety stroke hemiplegic patients were randomly assigned to the conventional treatment group (as the convention group), the Back-shu point needling group, and the combination of Back-shu point needling and the trunk exercise group, 30 patients in each group. They were treated with the conventional treatment, needling at Back-shu point, and the combination of needling at Back-shu point and trunk exercise. The Fugl-Meyer score (FMA) and modified Barthel index (MBI) score were assessed before treatment and two months after treatment.</p><p><b>RESULTS</b>The three rehabilitation treatment methods were all effective in improving the motor function of stroke hemiplegic patients (P<0.05). The effects in the Back-shu point needling group and the combination of Back-shu point needling and the trunk exercise group were respectively superior to that in the conventional treatment group (P<0.05). The effect in the combination of Back-shu point needling and the trunk exercise group was superior to that in the Back-shu point needling group (P<0.05).</p><p><b>CONCLUSION</b>The combination of Back-shu point needling and the trunk exercise could improve the motor function of stroke hemiplegic patients, and its effect was better than needling at Back-shu point alone.</p>

ABSTRACT

<p><b>BACKGROUND</b>Mycoplasma pneumoniae (M. pneumoniae) is a frequent cause of respiratory tract infections. However, there is deficient knowledge about the clinical manifestations of M. pneumoniae infection. We described the clinical and laboratory findings of M. pneumoniae pneumonia in hospitalized children who were all diagnosed by a ≥ fourfold increase in antibody titer.</p><p><b>METHODS</b>M. pneumoniae antibodies were routinely detected in children admitted with acute respiratory infection during a one-year period. The medical history was re-collected from children whose M. pneumoniae antibody titer increased ≥ fourfold at the bedside by a single person, and their frozen paired serum samples were measured again for the M. pneumoniae antibody titer.</p><p><b>RESULTS</b>Of the 635 children whose sera were detected for the M. pneumoniae antibody, paired sera were obtained from 82 and 29.3% (24/82) showed a ≥ fourfold increase in antibody titer. There were 24 cases, nine boys and 15 girls, aged from two to 14 years, whose second serum samples were taken on day 9 at the earliest after symptom onset; the shortest interval was three days. All children presented with a high fever (≥ 38.5°C) and coughing. Twenty-one had no nasal obstruction or a runny nose, and five had mild headaches which all were associated with the high fever. The disease was comparatively severe if the peak temperature was > 39.5°C. All were diagnosed as having pneumonia through chest X-rays. Four had bilateral or multilobar involvement and their peak temperatures were all ≤ 39.5°C. None of the children had difficulty in breathing and all showed no signs of wheezing.</p><p><b>CONCLUSIONS</b>The second serum sample could be taken on day 9 at the earliest after symptom onset meant that paired sera could be used for the clinical diagnosis of M. pneumoniae pneumonia in children at the acute stage. M. pneumoniae is a lower respiratory tract pathogen. Extrapulmonary complications were rare and minor in our study. High peak temperature (> 39.5°C) is correlated with the severity of M. pneumoniae pneumonia in children.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the value of percutaneous radiofrequency ablation (PRFA) combined with transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the management of recurrent small hepatocellular carcinoma.</p><p><b>METHODS</b>Between March 2001 and March 2005, 52 patients with recurrent hepatocellular carcinoma (tumor size< or =5 cm) underwent PRFA, and 14 of the patients (tumor size 3-5 cm) also received TACE and PEI, and their clinical data were analyzed retrospectively.</p><p><b>RESULTS</b>MRI or CT after PRFA revealed complete coagulative necrosis of the tumor in 38 cases (tumor size <3 cm). In the 14 patients (tumor size 3-5 cm) with also TACE and PEI, complete necrosis occurred in 11 cases (78.6%). In the patients involved in this study, the 1-, 2-, 3- and 4-year survival rates were 96.2%, 69.4%, 45.5% and 30.0%, respectively.</p><p><b>CONCLUSIONS</b>PRFA is an effective modality for local treatment of recurrent small hepatocellular carcinoma, capable of total elimination of tumors <3 cm. For tumors of 3-5 cm, combination with TACE and PEI may help increase the tumor necrosis rate following the ablation and raise the patients' survival rate.</p>

ABSTRACT

Methods for studying the population diversity of microorganism in activated sludge usually require enrichment of bacterial genome.The efficient information on microbial species composition provided and shifted in diversity revealed are dependent on the effective DNA recovery technique.The method was based on washing by alkaline phosphate buffer and digestion with extended heating of the activated sludge suspension in the presence of lysozyme and freeze-thawing in high-salt-SDS buffer.The extraction was tested for four activated sludge differing in places and dates.The DNA fragment from all sludge was integrity.DNA yields ranged from 105 to 823 ?g/g sludge and were of sufficient purity for PCR-based 16S ribosomal DNA analysis and restriction digested.In general,all methods produced DNA pure were not enough for PCR amplification and libraries construction.As basis of experimental goals,the study provides an appropriate extraction method of microbial DNA in sludge.
