ObjectiveTo provide evidence for strengthening tuberculosis control in Inner Mongolia by analyzing changes and influencing factors in public awareness of tuberculosis prevention and control information among residents between the early stage and 17 years after the implementation of the directly observed treatment， short-course （DOTS） strategy. MethodsBased on the "National Public Knowledge， Belief and Behavior Questionnaire on Tuberculosis Prevention and Control" designed by the Chinese Center for Disease Control and Prevention， a questionnaire survey was conducted among residents in Inner Mongolia using a multi-stage stratified random sampling method. Chi-square test was used for univariate analysis， and binary Logistic regression was employed to explore the influencing factors of public awareness of tuberculosis prevention and control information. ResultsThe overall awareness rate of core information on tuberculosis prevention and control among the public was 67.7% in 2006， and it decreased to 49.2% in 2023 （P<0.05）. Multivariate Logistic regression analysis showed， compared with the groups aged 15-29， illiterate and semi-illiterate， those with public medical care， and those with three or fewer family members， the awareness rate of the groups aged 60 and above （OR=0.689）， those with primary and junior high school education （OR=0.856）， and those with self-paid medical care （OR=0.468） was significantly lower in 2006. The awareness rate was relatively high in groups with more than 3 family members （OR=1.236） （P<0.05）. Compared with the groups aged 15-29， illiterate and semi-illiterate， married， Han ethnicity， employed， and those receiving public medical care， the awareness rate was higher among the groups aged 30-59 （OR=1.976）， 60 and above （OR=2.224）， those with high school education and above （OR=2.801）， and single （OR=2.244） in 2023. However， the awareness rates of ethnic minorities （OR=0.737）， the unemployed （OR=0.557）， and self-funded medical care （OR=0.497） groups were significantly lower （P<0.05）. ConclusionPublic awareness of TB prevention knowledge in Inner Mongolia remains suboptimal. Strengthening diversified health education campaigns， addressing social stigma， and improving healthcare access are critical to enhance regional TB control outcomes.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective: To explore the therapeutic mechanism of puerarin in treating rheumatoid arthritis (RA) rats based on the serine/tyrosine protein kinase B (AKT)-phosphorylated forkhead box protein O1 (FOXO1)-interleukin-9 (AKT-FOXO1-IL-9) signaling pathway. Methods : 36 rats were randomly divided into a blank group , a model group , a positive control group , and low , medium , and high dose groups of puerarin. Except for the blank group , the other groups were induced with type Ⅱ collagen to establish a RA rat model. After successful modeling , different doses of puerarin and methotrexate were given to treat the rats. The body mass and toe thickness of the rats were measured , and biochemical indicators of rat blood rheology were detected. X-ray was used to observe changes in rat joint morphology. Safranin green staining were used to observe the pathology of rat joint tissue. ELISA was used to detect the levels of IL-9 and rheumatoid factors in rat serum , and Western blot was used to detect changes in levels of AKT and FOXO1 . 36 rats were randomly divided into a blank group , a model group , a positive control group , and low , medium , and high dose groups of puerarin.

ELISA was used to detect the levels of IL-9 and rheumatoid factors in rat serum , and Western blot was used to detect changes in levels of AKT and FOXO1 . Results: Compared with the blank group , the model group had the lowest toe thickness , and X-ray images showed more obvious segmental stenosis and more severe marginal bone invasion ; scaly like changes appeared at the edges of joints stained with safranin green , accompanied by the exudation of inflammatory cells and increased proliferation and secretion of chondrocytes ; the expression levels of inflammatory factors IL-9 and rheumatoid factors were the highest , and the expression levels of AKT and FOXO1 proteins were the highest (P < 0. 05) . Compared with the model group , the toe thickness of rats treated with different doses of puerarin decreased ; X-ray images showed that the puerarin treatment group of rats showed improvement in plantar joint stenosis and marginal bone invasion ; the results of safranin green staining showed that after treatment with different doses of puerarin , the infiltration of inflammatory cells decreased , and the expression levels of inflammatory factor IL-9 , rheumatoid factors , AKT , and FOXO1 proteins decreased significantly ( P < 0. 05 ) , with the high-dose puerarin group showing the most significant difference. Compared with the high-dose puerarin group , the positive control group showed a significant decrease in the above results and statistical differences (P < 0. 05) . Conclusion Puerarin has a good therapeutic effect on rats with RA by inhibiting the AKT-FOXO1-IL-9 pathway. The high-dose puerarin group (60 mg/kg) has the best therapeutic effect and the results show a dose-response relationship.

Objective To heterologously express and purify the small ubiquitin-like modifier(SUMO)tag fused organo-phosphorus hydrolase mutant H257Y/L303T(YT),namely SUMO-YT,and evaluate its hydrolytic capacity against ethyl paraoxon and soman.Methods The SUMO tag encoding gene was constructed at the N-terminus of the YT encoding gene with a linker sequence via enzyme digestion and ligation before SUMO-YT was expressed in Escherichia coli.SUMO-YT and YT were purified through ammonium sulfate precipitation and affinity chromatography to obtain high-purity target proteins.The activity and kinetic parameters of the recombinant enzymes were examined using ethyl paraoxon and soman as substrates.Results The system for expression and purification of recombinant enzymes was established,yielding SUMO-YT and YT,and the former exhibited more significantly enhanced hydrolytic efficiency than the latter,with catalytic rates 11-fold higher for paraoxon and 4.4-fold higher for soman.At 37 ℃ and pH 7.2,SUMO-YT reduced the inhibition rate of acetylcholinesterase(AChE)by soman from 100％to 45.7％within 3 minutes,whereas YT reduced it to no more than 80％.Conclusion The high-activity recombinant SUMO-YT is prepared.SUMO tag fusion can significantly enhance the hydrolytic capacity of YT against ethyl paraoxon and soman.

Objective To investigate the nutritional status and dietary structure of tuberculosis patients among dif-ferent populations, analyze the factors influencing the nutritional status of tuberculosis patients, and provide theo-retical basis for improving clinical nutrition and related issues in tuberculosis patients.Methods Tuberculosis pa-tients, non-tuberculosis patients, and healthy individuals were randomly selected for a questionnaire survey.De-scriptive analysis was conducted using SPSS 20.0 software.Statistical description was performed using rates and composition ratios, and qualitative data were described using relative numbers.Chi-square test was used to compare overall rates and composition ratios among different health conditions groups, with a significance level of α=0.05.Independent factors analysis of nutritional status body mass index (BMI) was conducted using multiple Logistic re-gression analysis for variables with statistically significant differences in the univariate analysis.Results There were differences in the nutritional status (x2 =62.184, P<0.05) and dietary diversity score (x2 =64.049, P<0.05) among tuberculosis patients, non-tuberculosis patients, and healthy individuals.Univariate analysis of nutri-tional status BMI showed statistically significant differences in gender, smoking, meat-based diet, vegetable-based diet, moderate diet diversity score, and 6 other variables for tuberculosis patients (P <0.05) , and in gender, age, ethnicity, marital status, occupation, education level, smoking, drinking white wine, drinking beer, meat-based diet, moderate diet, and 11 other variables for healthy individuals (P<0.05) .The variables with statisti-cally significant differences in the univariate analysis were included in the multiple ordinal logistic regression analy-sis model for both tuberculosis patients and healthy individuals.The results showed that the level of education, veg-etable intake, moderate food diversity score (DDS) of 4-6 were independent influencing factors of nutritional sta-tus BMI among tuberculosis patients (P<0.05);marital status was an independent influencing factor of nutritional status BMI among non-tuberculosis patients (P<0.05);while gender and occupation were independent influencing factors of nutritional status BMI among healthy individuals (P<0.05).Conclusion The dietary nutritional status of the three population groups varied.Targeted health education should be conducted, especially for tuberculosis patients, to address the issue of uneven dietary intake and promote good dietary habits among local tuberculosis pa-tients.

Objective:To investigate the characteristics of anorectal dynamics in elderly patients with functional defecation disorders(FDD), and to provide a basis for their diagnosis, treatment and prevention.Methods:In this retrospective study, 226 patients with FDD receiving 3D high-resolution anorectal manometry were divided into an elderly group(93 cases)and a non-elderly group(133 cases). Results from anorectal manometry parameters were compared and analysis of patterns of anorectal pressure changes in elderly participants based on sex, the Bristol stool classification and clinical symptoms was conducted.Results:The resting anal pressure, rectal pressure and anal relaxation rate were lower( t=-3.407, -2.051, Z=2.548, P=0.001, 0.040, 0.011)and the volume of first sensation was higher( t=1.998, P=0.047)in the elderly group than in the non-elderly group.The maximum anal squeezing pressure, residual anal pressure and maximum tolerated volume were higher( t=4.589, 4.730, 2.025, all P<0.05), whereas the anal relaxation rate and anorectal pressure gradient were lower in elderly men than in elderly women( Z=4.059, t=-3.714, P<0.001 for both). Regarding the types of FDD, both the elderly group and the non-elderly group were dominated with type Ⅱ defecation disorder, with more men than women having type Ⅱ defecation disorder in the elderly group( χ2=10.343, P=0.001). In cases of paradoxical sphincter contraction during simulated defecation, the incidence in the elderly group was 80.65%(75/93), which was higher than 68.42%(91/133)in the non-elderly group( χ2=4.194, P=0.041). The volume of first sensation, volume of first defecation sensation, and maximum tolerated volume of patients in the elderly group without the urge to defecate were(59.86±23.84)ml, (96.76±34.61)ml, and(144.32±30.57)ml, respectively, higher than those of patients with the urge to defecate(46.79±17.20)ml, (75.26±28.75)ml, and(120.00±40.28)ml( t=-2.241, -2.493, -2.891, P=0.027, 0.014, 0.005). The rectal pressure(26.52±16.08)mmHg of patients with defecation dyssynergia was lower than that of patients without defecation dyssynergia(39.91±8.82)mmHg(1 mmHg=0.133 kPa)( t=-3.128, P=0.002), while the resting anal pressure of patients with defecation dyssynergia(90.60±28.44)mmHg was higher than that of patients without defecation dyssynergia(73.65±27.10)mmHg( t=-2.201, P=0.030). The resting anal pressure and maximum anal squeezing pressure in patients with anal blockage sensation[(87.11±24.64)mmHg, (149.28±48.29)mmHg]were higher than those in patients without anal blockage sensation[(72.43±20.02)mmHg, (121.76±26.35)mmHg]( t=2.954、3.066, P=0.004、0.003). There was no significant difference in values from parameters of anorectal dynamics between patients with different Bristol stool types, with and without incomplete defecation or with different degrees of abdominal distension(all P>0.05). Conclusions:Anorectal dynamics in patients with FDD are characterized by paradoxical anal sphincter movements, but older patients with FDD are mainly characterized by inadequate rectal propulsion, pelvic floor muscle dysfunction and reduced rectal sensitivity.

Objective To investigate the cognition of colorectal cancer-related knowledge and influencing factors of patients with middle- and advanced-stage colorectal cancer in ethnic minority areas of Inner Mongolia. Methods According to the national population and the prevalence of colorectal cancer, 277 patients with colorectal cancer were selected by stratified and random sampling in Inner Mongolia. The patients were surveyed in Baotou, Chifeng, Bayannaoer, and other hospitals. The questionnaire included patients' basic information, cognition of colorectal cancer risk factors and screening knowledge, screening information, etc. Results Before suffering from the disease, the patients' knowledge of colorectal cancer (risk factors, early screening knowledge, treatment methods) was low. About 54.9% of patients were unaware of high risk factors for colorectal cancer, 75.8% of patients did not understand the knowledge of early screening of colorectal cancer, and 37.5% of patients did not underst and the treatment of colorectal cancer. The main influencing factors of colorectal cancer cognition were education level and occupation. Patients who work in institutions and enterprises and with higher education level had better cognition. Conclusion Patients with middle- and advanced-stage colorectal cancer in Inner Mongolia have poor knowledge and awareness of risk factors and screening of colorectal cancer before diagnosis. Education level and occupation are factors influencing colorectal cancer cognition, therefore, people with low knowledge rate of colorectal cancer and low education level as well as unemployed laid-off people should be given priority intervention.

Objective To understand and evaluate the knowledge, attitude and practice of female human papillomavirus and HPV vaccine in Chinese mainland. Methods We searched the relevant studies about the knowledge, attitude and behavior factors of HPV infection and HPV vaccine published in PubMed, MEDLINE, CNKI and Wanfang databases about Chinese mainland women from January 1, 1995 to January 31, 2021.Two researchers independently screened the literatures, extracted data and the literatures with quality score≥5 points.Chi square test was used to evaluate its heterogeneity.Begg' s test was used to evaluate publication bias. Results A total of 33 literatures were included, with a total number of 46013 people.The results showed that the total awareness rate of HPV in the population was 65.9%, the lowest rates were 16.0%, 41.2% and 14.4% in Northeast, rural areas and middle school students, respectively; while the highest rates of HPV were 77.4%, 56.3% and 71.0% in Central China, cities and towns and college students, respectively.The main source of HPV knowledge was the network/WeChat official account number (38.9%), and the lowest was family/friend (4.5%).The population's awareness rate of HPV vaccine related knowledge was 41.4%, the highest rates were 51.8% and 69.7% in East China and medical staff, respectively, while the lowest were 23.6% and 12.7% in Southwest and middle school students. Conclusion In order to achieve the total elimination of cervical cancer in China by 2030 as soon as possible, people should strengthen their awareness of HPV and HPV vaccine related knowledge.

Objective: To understand the epidemic status and influencing factors of Mongolian children with ASD in central and eastern Inner Mongolia, so as to provide data support for formulating prevention and intervention strategies and improving the overall epidemiological investigation of ASD in Inner Mongolia. Methods: Sixteen kindergartens and primary schools were selected from Chifeng City, Ulanqab City, Tongliao City, Hulunbuir City and Xilingol League cities in Inner Mongolia by means of random cluster sampling. Firstly, 7 108 children aged 3-14 were initially screened with the Kirschner Autism Behavior Scale(CABS), and then the children with ASD positive were given the autism behavior test scale (ABC). According to the diagnostic criteria, the professionals, including chief physicians and associate chief physicians from the major of child psychiatry, diagnosed ASD with the total score of ABC scale ≥62. Univariate and Logistic regression multivariate analysis were carried out among Mongolian children to find out the influencing factors related to the occurrence of Mongolian ASD in Inner Mongolia. Results: The prevalence of Mongolian children was 0.37%. Mongolian ASD group and Mongolian normal children series in the household register, habitual twitch, hyperactivity, bite lips, families have extreme introverts, mothers age, father s cultural level, cultural degree of mother, father mother mild character, irritable, neonatal diseases, fetal gestational age distribution had statistical significance( χ 2/Z= 12.58 , 16.68, 14.93, 64.43, -3.76, -2.86, 4.57, 11.12, 12.33, 16.66, P <0.05). Conclusion Measures such as shaping a healthy growth environment, adjusting parental style, paying attention to the level of early childhood language development, and preventing neonatal diseases might lower the risk of ASD in children.
