ABSTRACT
Objective To explore the intervention effects of lentinan on sodium arsenite (SA) induced hepatotoxicity in mice. Methods Healthy male C57BL/6 mice were used as experimental subjects and divided into 4 groups, namely control group, SA treatment group, lentinan intervention + SA exposure group, and lentinan intervention control group. The mice were given oral SA (10.0 mg/kg.bw, once every other day) for 14 days, and then the liver tissues and serum samples were collected. Hematoxylin-eosin (HE) was used to evaluate the characteristics of hepatic pathological damage. Enzyme-linked immunosorbent assay (ELISA), Flow Cytometry (FC) and Western-blotting (WB) were used to detect the levels of hepatic function, oxidative stress, CD4+ type 17 helper T cells (Th17), and inflammatory cytokines. Results Compared with the control group, the arsenic exposure group showed obvious hepatic pathological injury and increased levels of serum ALT (8.78±0.76 vs 5.47±0.49) and AST (12.42±1.87 vs 7.14±0.57), FC experiments showed that the Th17 content in liver tissues increased (67.70±4.94 vs 7.36±1.50), and ELISA showed that the antioxidant GSH content decreased (593.40±23.25 vs 730.94±30.81), and the levels of MDA (74.56±7.63 vs 49.90±6.42) and proinflammatory cytokines IL-17A (162.48±10.75 vs 118.53±7.92) and IL-1β (512.50±24.78 vs 462.48±22.15) increased in hepatic tissues (P < 0.05). Compared with the arsenic exposure group, the lentinan showed a significant antagonistic effect after intervention (P < 0.05). Compared to SA exposure group, WB analysis showed that compared with the arsenic exposure group, the expression levels of IL-17A (0.47±0.08 vs 0.89±0.11) and NLRP3 inflammasome (0.80±0.09 vs 1.09±0.16) in the liver tissues of the lentinan intervention group were significantly decreased (P < 0.05). Conclusion Lentinan alleviates SA-induced hepatic injury in mice, which may be mediated through the inhibition of Th17-IL-17A inflammatory signaling.
ABSTRACT
OBJECTIVE@#To establish a quantitative evaluation parameter system for basic acupuncture manipulations based on 3D motion tracking technology, and to further analyze the characteristics of acupuncture manipulation.@*METHODS@#The motion tracking system Simi Motion Ver.8.5 was used to collect parameters of acupuncture manipulations, so as to establish a quantitative evaluation system mainly in spatial control parameters, time control parameters and stability parameters. Based on the evaluation parameter system, data of acupuncture manipulations (even reinforcing-reducing manipulation using lifting-thrusting technique and twirling technique) were collected from 19 teachers majored in acupuncture-moxibustion, of which the characteristics were analyzed and were compared with the results tested by traditional ATP-Ⅱ acupuncture manipulation parameter determination apparatus (ATP-Ⅱ).@*RESULTS@#The evaluation parameter system could quantitatively analyze the basic acupuncture manipulations in 3 aspects, i.e. space, time and stability. Acupuncture manipulations were performed by shifting the needle body in a certain range along X, Y and Z axes. The amplitude and speed of thumb movement were greater than those of index finger. The time-history of lifting was similar to thrusting, while the time-history of twirling to left was similar to twirling to right in even reinforcing-reducing manipulation. The coordinate-time curve of finger movement of the evaluation system had consistent wave pattern compared with the voltage-time curve generated by ATP-Ⅱ.@*CONCLUSION@#The quantitative evaluation parameter system based on 3D motion tracking technology can objectively evaluate basic acupuncture manipulations, and show the characteristics of different manipulations and the movement details of finger joints.

Objective:To evaluate the post-marketing safety and immunogenicity of a 23-valent pneumococcal polysaccharide vaccine (PPV23).Methods:From September 2020 to June 2021, a clinical trial of single-dose PPV23 was conducted in people ≥3 years old in Centers for Disease Control and Prevention of Guizhou, Hunan and Fujian provinces. Blood samples were collects from the subjects before and 30 d after vaccination. ELISA was used to quantitatively detect IgG antibodies against capsular polysaccharides of 23 Streptococcus pneumoniae serotypes in serum samples. The adverse events (AEs) were monitored within 7 d after vaccination. Results:A total of 409 subjects were enrolled and included in safety analysis. Except for one with antibody level inversion, the other 408 participants were included in immunogenicity analysis. The levels of antibodies against the 23 Streptococcus pneumoniae serotypes were all increased after vaccination by an average of 4.24 folds. The two-fold growth rates of the antibodies ranged from 51.72% to 96.81% with a total two-fold growth rate of 78.59%. The overall rate of AEs was 27.14% (111/409). Local AEs were mainly pain, induration, redness and swollen. No serious adverse events related to vaccination occurred. Conclusions:This study preliminarily demonstrated the good immunogenicity and safety of PPV23 vaccine.
ABSTRACT
Objective:To investigate the effect of multiple medications on the risk of small intestinal bacterial overgrowth(SIBO)in the elderly.Methods:Clinical data of 85 inpatients in the Department of Geriatrics, the First Hospital of Lanzhou University undergone HMBT from August 2017 to April 2021 were retrospectively analyzed.According to the HMBT results, they were divided into a SIBO(+ )group and a SIBO(-)group.Polypharmacy was defined as ≥ 5 types of medications.We analyzed the difference in the rate of polypharmacy between the two groups.Results:A total of 85 hospitalized elderly patients were included in the study.Of these patients, 38(44.71%)tested positive for SIBO.Polypharmacy occurred in 41 patients(48.24%). There were significant differences in types of drugs and polypharmacy between the SIBO(+ )group and the SIBO(-)group( t=3.01 and χ2=14.33, P<0.05 for both). Moreover, polypharmacy was a risk factor for SIBO( P=0.017, OR=10.85, 95% CI: 1.52-77.29). Among 14 commonly used drugs, gastrointestinal motility drugs were closely related to SIBO.There was a positive correlation between polypharmacy and the change in hydrogen levels at 90 min( P=0.040, r=0.22, 95% CI: 0.01-0.42). Conclusions:Polypharmacy is correlated with SIBO in the elderly, is a risk factor for SIBO and is helpful in clinical practice to assess the risk of SIBO and decide further examinations, contributing to early diagnosis and early treatment.
ABSTRACT
Objective: To evaluate the therapeutic and prognostic outcomes of transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OSCC). Methods: A retrospective study of 99 OSCC patients treated with TORS in Department of Head and Neck Surgery, Sun Yat-sen University Cancer Center between April 2017 and May 2021 was conducted. There were 84 males and 15 females, with an age range of 35-85 years. Patients' clinical characteristics, including clinical staging, HPV infection status, perioperative management and postoperative adjuvant treatment, were recorded. The overall survival (OS) and progression-free survival (PFS) were analyzed. The survival outcomes were analyzed with Kaplan-Meier method and Log-rank test. Results: The hospital stay of OSCC patients with TORS was (5.3±2.9) days and the average time of postoperative nasal feeding tube indwelling was (15.2±10.8) days. Among the 99 patients, 21 (21.2%) received tracheotomy and the average time of tracheotomy tube indwelling was (11.9±11.4) days. The two-year OS and PFS in patients with follow-up over two years were 94.0% and 87.7%, respectively and the three-year OS and PFS of patients with follow-up over three years were 94.0% and 78.9%, respectively. The two-year OS and PFS were respectively 97.4% and 88.9%, for patients with stages I-II and 86.8% and 88.9% for patients with stages III-IV. HPV-negative and HPV-positive patients had respectively two-year OS (100.0% vs. 91.5%) and PFS (88.9% vs. 87.2%). There was no significantly statistical difference in survival between patients with and without adjuvant radiotherapy after TORS (82.6% vs. 90.5%, HR=0.52, 95%CI: 0.12-2.23, P=0.400). Conclusions: TORS is more suitable for the treatment of patients with early (Ⅰ-Ⅱ) or HPV-positive oropharyngeal squamous cell carcinoma, and the recovery after TORS treatment is good.

This paper reviews the domestic and foreign studies published in 2020 on the application of influenza vaccine in populations at high risk. The importance of influenza vaccination in population at high risk has been proved by larger sample, multicentre, high-quality evidence-based studies. Influenza vaccination is the most cost-effective measure to prevent influenza. However, the coverage rate of influenza vaccine is very low in China, it is necessary to strengthen the health education to promote influenza vaccination in different populations. It is recommended to give influenza vaccination to the population in whom influenza vaccination has been proven safe and effective before influenza season. Research of the safety, efficiency and cost-effectiveness of influenza vaccine should be accelerated for the populations in whom such data are lacking or insufficient.

Objective: To evaluate the indications, safety, feasibility, and surgical technique for patients with head and neck cancers undergoing transoral robotic retropharyngeal lymph node (RPLN) dissection. Methods: The current study enrolled 12 consecutive head and neck cancer patients (seven males and four females) who underwent transoral robotic RPLN dissection with the da Vinci surgical robotic system at the Sun Yat-sen University Cancer Center from May 2019 to July 2020. Seven patients were diagnosed as nasopharyngeal carcinoma with RPLN metastasis after initial treatments, 4 patients were diagnosed as thyroid carcinoma with RPLN metastasis after initial treatments, and one patient was diagnosed as oropharyngeal carcinoma with RPLN metastasis before initial treatments. The operation procedure and duration time, intraoperative blood loss volume and complications, nasogastric feeding tube dependence, tracheostomy dependence, postoperative complications, and hospitalization time were recorded and analyzed. Results: All patients were successfully treated by transoral robotic dissection of the metastatic RPLNs, none of which was converted to open surgery. RPLNs were completely resected in 10 patients, and partly resected in 2 patients (both were nasopharyngeal carcinoma patients). The mean number of RPLN dissected was 1.7. The operation duration time and intraoperative blood loss volume were (191.3±101.1) min and (150.0±86.6) ml, respectively. There was no severe intraoperative complication such as massive haemorrhage or adjacent organ injury during surgery. Nasogastric tube use was required in all patients with (17.1±10.6) days of dependence, while tracheotomy was performed in 8 patients with (11.6±10.7) days of dependence. The postoperative hospitalization stay was (8.5±5.7) days. Postoperative complications occurred in 4 patients, including 2 of retropharyngeal incision and 2 of dysphagia. During a follow-up of (6.5±5.1) months, disease-free progression was observed in all patients, 10 patients were disease-free survival and other 2 patients were survival with tumor burden. Conclusions: The transoral robotic RPLN dissection is safety and feasible. Compared with the traditional open surgical approach, it is less traumatic and safer, has fewer complications and good clinical application potentiality. The indications for transoral robotic RPLN dissection include thyroid carcinoma, oropharyngeal carcinoma, and some selected nasopharyngeal carcinoma and other head and neck cancers. Metastatic RPLNs from some nasopharyngeal carcinoma with incomplete capsule, unclear border and adhesion to the surrounding vessels are not suitable for transoral robotic RPLN dissection.

AIM: To analyze the correlation of changes in non-contact intraocular pressure(IOPNCT)and the surgical parameters after femtosecond laser small incision lenticule extraction(SMILE)for high myopia.MOTHODS:A retrospective analysis, the clinical data of 98 patients(196 eyes)with high myopia were operated SMILE in the optometric center of Gansu Provincial Hospital from January 2018 to July 2019 were analyzed. The change of IOPNCT before and after operation was observed, and recorded the optical zone(OZ), lenticule thickness(LT), cap thickness(CT)and residual stromal thickness(RST)and the correlation with the change value of IOPNCT(△IOPNCT, △IOPNCT=IOPpreoperative-IOP postoperative at 6mo).RESULTS:After operation at 1d, 1wk, 1,3 and 6mo, the group of patients with IOPNCT(10.84±2.14,11.00±2.19,10.65±2.43,10.45±2.04,10.61±1.39mmHg)and the preoperative(16.79±1.65mmHg)comparison have a difference(P<0.001).The optical zone and lenticule thickness were positively correlated with △IOPNCT respectively(r=0.1537, 0.8161, all P<0.05). The cap thickness and residual stromal thickness were negatively correlated with △IOPNCT respectively(r=-0.8362, -0.3351, all P<0.0001). Introduce the above related factors into a multiple linear regression analysis model. The regression coefficients of variables are statistical significane. The regression equation was Y=16.189+0.227X1+0.032X2-0.083X3-0.007X4(Y=△IOPNCT, X1=OZ, X2=LT, X3=CT, X4=RST). The equation was statistically significant(F=195.704, P<0.001), and the regression model coefficient of determination R2=0.901.CONCLUSION:The intraocular pressure changes after SMILE with high myopic were correlated with optical zone, lenticule thickness, cap thickness and residual stromal thickness. The regression equation would provide reference to evaluation the real intraocular pressure after SMILE in clinic.
ABSTRACT
Objective:To evaluate the difference in safety and immunogenicity of live rotavirus vaccine (oral) and measles, mumps and rubella (MMR) vaccine immunized alone or in combination.Methods:This study recruited 1 752 children aged 8-9 months who had not been vaccinated with live rotavirus vaccine (oral) or MMR vaccine after birth. The subjects were divided into three groups: study group (652 subjects, immunized with live rotavirus vaccine and MMR vaccine), control group 1 (723 subjects, immunized with live rotavirus vaccine) and control group 2 (377 subjects, immunized with MMR vaccine). Local and systemic adverse reactions within 30 d after vaccination were recorded. Serum samples were collected before and 35-42 d after immunization for analyzing the changes in antibodies.Results:Immunization alone or in combination with live rotavirus vaccine (oral) and MMR vaccine achieved similar results in the positive rates and concentrations of antibodies against rotavirus, measles and rubella viruses ( P>0.05). Moreover, the positive rates and the concentrations of the three antibodies were increased after vaccination. Compared with the control group 2, the concentration of antibody against mumps virus in the study group was increased ( P<0.05), but no significant difference in the positive rate of antibody against mumps virus was found between the two groups ( P>0.05). The positive rate and the concentration of antibody against mumps virus were increased after combined immunization or immunization with MMR vaccine alone. The overall incidence of fever and diarrhea was 1.54% (27/1 752) and 0.63% (11/1 752). No other abnormal reactions, incidental reactions or adverse reactions of any clinical significance were observed. Conclusions:Live rotavirus vaccine (oral) and MMR vaccine immunized alone or in combination showed good immunogenicity and safety.
ABSTRACT
Objective: To explore the clinical effects of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns. Methods: A retrospective observational study was conducted. From May 2018 to April 2021, 12 male patients with thumb destructive defects caused by electrical burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, aged 27 to 58 years, including 10 cases with degree Ⅲ thumb defect and 2 cases with degree Ⅳ thumb defect after thorough debridement. The thumb was reconstructed with free hallux-nail flap combined with composite tissue flap of the second phalangeal bone, joint, and tendon with skin island. The donor site of hallux-nail flap was covered with artificial dermis in the first stage and performed with continuous vacuum sealing drainage, and covered with medium-thickness skin graft from the groin site in the second stage. The donor site in the second toe was filled and fixed with iliac bone strips. The survival of reconstructed thumb was observed 1 week after the reconstruction surgery, the survival of skin graft in the donor site of hallux-nail flap was observed 2 weeks after skin grafting, and the callus formation of the reconstructed thumb phalanx and the second toe of the donor foot was observed by X-ray 6 weeks after the reconstruction surgery. During the follow-up, the shape of reconstructed thumb was observed and the sensory function was evaluated; the function of reconstructed thumb was evaluated with trial standard for the evaluation of the functions of the upper limbs of the Hand Surgery Society of the Chinese Medical Association; whether the interphalangeal joints of the hallux and the second toe were stiff, the scar hyperplasia of the foot donor site, and whether the walking and standing functions of the donor feet were limited were observed. Results: One week after the reconstruction surgery, all the reconstructed thumbs of the patients survived. Two weeks after skin grafting, the skin grafts in the donor site of hallux-nail flap of 11 patients survived, while the skin graft in the donor site of hallux-nail flap of 1 patient was partially necrotic, which was healed completely after 10 days' dressing change. Six weeks after the reconstruction surgery, callus formation was observed in the reconstructed thumb and the second toe of the donor foot of 10 patients, the Kirschner wires were removed; while callus formation of the reconstructed thumb was poor in 2 patients, and the Kirschner wires were removed after 2 weeks of delay. During the follow-up of 6 to 24 months, the shape of reconstructed thumb was similar to that of the healthy thumb, the discrimination distance between the two points of the reconstructed thumb was 7 to 11 mm, and the functional evaluation results were excellent in 4 cases, good in 6 cases, and fair in 2 cases. The interphalangeal joints of the hallux and the second toe of the donor foot were stiff, mild scar hyperplasia was left in the donor site of foot, and the standing and walking functions of the donor foot were not significantly limited. Conclusions: The application of free hallux-nail flap combined with the second toe composite tissue flap in the reconstruction of damaged thumb after electrical burns adopts the concept of reconstruction instead of repair to close the wound. It can restore the shape and function of the damaged thumb without causing great damage to the donor foot.

Objective: To explore the therapeutic effects of transoral robotic surgery (TORS) and traditional surgical modes in oropharyngeal squamous cell carcinoma (OPSCC). Methods: The clinicopathological data of patients with oropharyngeal squamous cell carcinoma treated at Sun Yat-sen University Cancer Center from 2010 to 2018 were retrospectively analyzed. 135 cases were treated with traditional surgery (non-TORS group), while 52 cases were treated with TORS (TORS group). The prognosis of the two groups of patients were analyzed by Kaplan-Meier method and Log rank test, the influencing factors were analyzed by Cox regression model. Results: The 2-year overall survival (OS, 94.2%) and 2-year progression-free survival (PFS, 93.8%) of patients in the TORS group were better than those in the non-TORS group (71.4% and 71.4%, respectively, P<0.05). The 2-year OS (93.3%) and 2-year PFS (92.8%) of TORS group patients in T1-2 stage were better than those of non-TORS group (73.1% and 72.8%, respectively, P<0.05). The 2-year OS (95.8%) and 2-year PFS (95.2%) of patients with stage Ⅰ to Ⅱ in the TORS group were not significantly different from those in the non-TORS group (84.1% and 83.9%, respectively, P>0.05). The 2-year OS (92.9%) and 2-year PFS rate (92.7%) of patients with stage Ⅲ to Ⅳ in the TORS group were better than those in the non-TORS group (64.7% and 63.9%, respectively, P<0.05). The 2-year OS (94.4%) of HPV-positive patients in the TORS group was not significantly different from that in the non-TORS group (83.3%, P=0.222). The 2-year OS of HPV-negative patients in the TORS group (94.1%) was significantly different from that in the non-TORS group (43.7%, P<0.001). HPV status was an independent prognostic factor (P=0.008). Conclusions: TORS has a better prognosis in the treatment of oropharyngeal squamous cell carcinoma compared with the traditional treatment methods. The patients with T1-T2 can achieve better survival benefits after TORS treatment. The HPV-positive OPSCC patients has a better prognosis than that of HPV-negative OPSCC patients, and regardless of HPV status, OPSCC patients in the TORS group could obtain a better survival prognosis.

The rapid development of terahertz technology promotes the realization of various terahertz imaging systems. Terahertz technology features terahertz waves as good non-invasive illumination sources due to their high spectral resolution, penetration and safety. The terahertz imaging technique (TIT) has gradually been extended from the biomedical field to the field of Chinese medicine (CM), and it has become a powerful tool for seeking scientific evidence for CM theories with the use of modern science and technology. This paper reviews the current application of TITs in the field of CM research, and most importantly offers novel proposals for the application of TITs in CM research from the perspective of CM syndrome objectification and acupuncture research and cites existing reports as reference to the feasibility of these new proposals.

OBJECTIVE@#To identify the pathogenic variants from a patient with suspected congenital contractural arachnodactyly, and to explore the possible molecular genetic pathogenesis, so as to provide evidence for clinical diagnosis.@*METHODS@#Whole exome sequencing was performed for the patient. The splicing site variation of candidate pathogenic genes was verified by Sanger sequencing, and the new transcript sequence was determined by RT-PCR and TA-cloning sequencing.@*RESULTS@#The patient carried a heterozygous c.533-1G>C variant of FBN2 gene, which was not reported. The sequencing of mRNA showed that the variant leaded to the disappearance of the canonical splice acceptor site of FBN2 gene and the activation of a cryptic splice acceptor site at c.533-71, resulting in the insertion of 70 bp sequence in the new transcript. It was speculated that the polypeptide encoded by the new transcript changed from valine (Val) to serine (Ser) at amino acid 179, and prematurely terminated after 26 aminoacids. According to the guidelines of American College of Medical Genetics and Genomics, the variant of FBN2 gene c. 533-1G>C was determined as pathogenic (PVS1+PM2+PP3 ).@*CONCLUSION@#A novel splicing variant of FBN2 gene (c.533-1G>C) was identified, which can lead to congenital contractural arachnodactyly.

Objective:To evaluate the effect of three teaching methods of case-based learning (CBL), problem-based learning (PBL) and blended learning (CBL+PBL) on the teaching of clinical clerkship of cardiovascular internal medicine among medical students.Methods:A total of 175 third-year medical students were divided into three groups (CBL, PBL and CBL+PBL). They entered the clinical clerkship in batches, and then received written examination and questionnaire survey after the teaching. The data were processed by SPSS 19.0 and were compared by one-way ANOVA or chi-square test (R × C) among groups.Results:The total average scores of students in CBL, PBL and CBL+PBL groups were 15.34±2.88, 14.67±2.98 and 17.13±2.82, respectively ( P<0.05), and the proportion of students with "excellent" scores were 27.4%(17/62), 14.5%(9/62) and 58.1%(36/162), respectively. Most students in CBL group did not agree that CBL helped to train literature access skills [70.7%(41/58)] or teamwork ability [82.8%(48/58)], compared with which 70.9%(39/55) in PBL group thought it helped to train literature access skills but only 7.3%(4/55) well accepted PBL. In addition, majority of students in CBL+PBL group believed it was helpful to gain learning interest [64.3%(36/56)] and train team cooperation ability [62.5%(35/56)], and [53.6%(30/56)] favored this teaching method. Conclusion:Compared with traditional CBL, PBL fails to attract students or improve teaching performance; while blended learning is benefited for the students and can improve teaching quality.
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.

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.
