BACKGROUND: Atrial fibrillation (AF) is a common cardiac arrhythmia in the elderly. This study aimed to evaluate urban-rural disparities in its prevalence and management in elderly Chinese. METHODS: Consecutive participants aged ≥ 65 years attending outpatient clinics were enrolled for AF screening using handheld single-lead electrocardiogram (ECG) from April 2017 to December 2022. Each ECG rhythm strip was reviewed from the research team. AF or uninterpretable single-lead ECGs were referred for 12-lead ECG. Primary study outcome comparison was between rural and urban areas for the prevalence of AF. The Student's t-test was used to compare mean values of clinical characteristics between rural and urban participants, while the Pearson's chi-square test was used to compare between-group proportions. Multivariate stepwise logistic regression analysis was performed to estimate the association between AF and various patient characteristics. RESULTS: The 29,166 study participants included 13,253 men (45.4%) and had a mean age of 72.2 years. The 7073 rural participants differed significantly (P ≤ 0.02) from the 22,093 urban participants in several major characteristics, such as older age, greater body mass index, and so on. The overall prevalence of AF was 4.6% (n = 1347). AF was more prevalent in 7073 rural participants than 22,093 urban participants (5.6% vs. 4.3%, P < 0.01), before and after adjustment for age, body mass index, blood pressure, pulse rate, cigarette smoking, alcohol consumption and prior medical history. Multivariate logistic regression analysis identified overweight/obesity (OR = 1.35, 95% CI: 1.17-1.54) in urban areas and cigarette smoking (OR = 1.62, 95% CI: 1.20-2.17) and alcohol consumption (OR = 1.42, 95% CI: 1.04-1.93) in rural areas as specific risk factors for prevalent AF. In patients with known AF in urban areas (n = 781) and rural areas (n = 338), 60.6% and 45.9%, respectively, received AF treatment (P < 0.01), and only 22.4% and 17.2%, respectively, received anticoagulation therapy (P = 0.05). CONCLUSIONS In China, there are urban-rural disparities in AF in the elderly, with a higher prevalence and worse management in rural areas than urban areas. Our study findings provide insight for health policymakers to consider urban-rural disparity in the prevention and treatment of AF.

Objective To explore the current status of H.pylori infection in the natural population of Sanya City,analyze its influencing factors,and provide a reference basis for the prevention and control of H.pylori infection.Methods A total of 677 residents from four districts of Sanya City were selected by overall stratified random sampling method,and were subjected to urea 14C breath test and questionnaire survey to calculate the positive rate of H.pylori in the natural population and analyze the influencing factors of H.pylori infection.Results A total of 606 residents were included,and the number of H.pylori positive detections was 261,with a positive detection rate of 38.5％.Among them,different ethnicity,marital status,smoking,eating vegetables and fruits,and literacy level were associated with H.pylori infection(P＜0.05);gender,age,BMI,alcohol consumption,drinking water source,betel quid chewing,and the number of cohabitants were not significantly associated with H.pylori infection(P＞0.05).Family infection was an independent risk factor for H.pylori infection in the natural population of Sanya City,and Li ethnicity,frequent consumption of fruits and vegetables,and college and higher education level were independent protective factors for H.pylori infection in the natural population of Sanya City.Conclusion The rate of H.pylori infection in the natural population of Sanya City is lower than the national average.Consuming more fruits and vegetables and improving the awareness of hygiene protection are conducive to the prevention of H.pylori infection;and the promotion of the family and related members with the same examination and treatment is important to avoid aggregation of infection within the family.

Objective To explore the relevant risk factors of H.pylori infection,and provide reference for prevention and treatment of H.pylori in this area,and further provide theoretical basis for the prevention and treatment of gastric cancer.Methods A total of 1200 residents in four districts of Haikou city were investigated by questionnaire and urea 14 C breath test by holistic stratified random sampling to calculate the population infection rate and analyze the risk factors of infection.Results The total infection rate was 32.5％,which was lower than the national H.pylori infection rate.No consumption of fruits and vegetables,no habit of washing hands before meals,and people with gastrointestinal symptoms,are independent risk factors of H.pylori infection.No consumption of pickled products is of great significance to prevent H.pylori infection.Conclusion The prevalence of H.pylori infection in the population of Haikou is lower than the national average,and H.pylori infection is closely related to the poor living habits of residents.

The cerebellum is heavily connected with other brain regions, sub-serving not only motor but also nonmotor functions. Genetic mutations leading to cerebellar dysfunction are associated with mental diseases, but cerebellar outputs have not been systematically studied in this context. Here, we present three dimensional distributions of 50,168 target neurons of cerebellar nuclei (CN) from wild-type mice and Nlgn3R451C mutant mice, a mouse model for autism. Our results derived from 36 target nuclei show that the projections from CN to thalamus, midbrain and brainstem are differentially affected by Nlgn3R451C mutation. Importantly, Nlgn3R451C mutation altered the innervation power of CN→zona incerta (ZI) pathway, and chemogenetic inhibition of a neuronal subpopulation in the ZI that receives inputs from the CN rescues social defects in Nlgn3R451C mice. Our study highlights potential role of cerebellar outputs in the pathogenesis of autism and provides potential new therapeutic strategy for this disease.

BACKGROUND: The relationship between quality of life at three months after lung cancer surgery and different surgical approaches is remains unclear. This study aimed to compare the quality of life of patients three months after uniportal and multiportal thoracoscopic lobectomy. METHODS: Data from patients who underwent lung surgery at the Department of Thoracic Surgery, Sichuan Cancer Hospital between April 2021 and October 2021 were collected. The European Organization for Research and Treatment of Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and Quality of Life Questionnaire-Lung Cancer 29 (EORTC QLQ-LC29) were used to collect quality of life data of the patients. Potential confounding factors in the baseline data were included in a multivariate regression model for adjustment, and the quality of life of the two groups three months postoperatively was compared with traditional clinical outcomes. RESULTS: A total of 130 lung cancer patients were included, with 57 males (43.8%) and 73 females (56.2%), and an average age of (57.1±9.5) yr. In the baseline data of the two groups, there was a statistical difference in the number of chest drainage tubes placed (P<0.001). After adjustment with the regression model, at three months postoperatively, there were no significant differences in all symptoms and functional status scores between the two groups (all P>0.05). The multiportal group had longer surgery time (120.0 min vs 85.0 min, P=0.001), postoperative hospital stay (6.0 d vs 4.0 d, P=0.020), and a higher incidence of early ≥ grade 2 complications (39.0% vs 10.1%, P=0.011) compared to the uniportal group. CONCLUSIONS Patients undergoing uniportal and multiportal thoracoscopic lobectomy have similar quality of life at three months postoperatively. The uniportal group may have certain advantages in terms of traditional clinical outcome indicators such as operation time, postoperative hospital stay, and early postoperative complications.

OBJECTIVE: To explore the feasibility and clinical effect of Stand-alone oblique lateral interbody fusion (OLIF) in the treatment of lumbar intervertebral disc degeneration with Modic changes and endplate sclerosis. METHODS: A retrospective analysis was performed on 16 cases with lumbar intervertebral disc degeneration with Modic changes and endplate sclerosis admitted to three medical centers from January 2015 to December 2018. There were 6 males and 10 females, the age ranged from 45 to 67 years old with an average of (55.48±8.07) years old, the medical history ranged from 36 to 240 months with an average of (82.40±47.68) months. The lesion sites included L_2,3 in 2 cases, L_3,4 in 5 cases, and L_4,5 in 9 cases. All patients presented with chronic low back pain with lower limb neurological symptoms in 3 cases. All patients were treated by Stand-alone oblique lateral lumbar interbody fusion. Clinical and radiological findings and complications were observed. RESULTS: There was no vascular injury, endplate injury and vertebral fracture during the operation. The mean incision length, operation time, and intraoperative blood loss were(4.06±0.42) cm, (45.12±5.43) min, (33.40±7.29) ml, respectively. The mean visual analogue scale (VAS) of the incision pain was (1.14±0.47) at 72 hours after operation. There was no incision skin necrosis, poor incision healing or infection in patients. Sympathetic chain injury occurred in 1 case, anterolateral pain and numbness of the left thigh in 2 cases, and weakness of the left iliopsoas muscle in 1 case, all of which were transient injuries with a complication rate of 25%(4/16). All 16 patients were followed up from 12 to 36 months with an average of (20.80±5.46) months. The intervertebral space height was significantly recovered after operation, with slight lost during the follow-up. Coronal and sagittal balance of the lumbar spine showed good improvement at the final follow-up. There was no obvious subsidence or displacement of the cage, and the interbody fusion was obtained. At the final follow-up, Japanese Orthopaedic Association(JOA) score and Oswestry disability index(ODI) were significantly improved. CONCLUSION As long as the selection of case is strict enough and the preoperative examination is sufficients, the use of Stand-alone OLIF in the treatment of lumbar intervertebral disc degeneration with Modic changes and endplate sclerosis has a good results, with obvious clinical advantages and is a better surgical choice.

Objective:To analyze the relationship between the high sensitivity C-reactive protein (hs-CRP) and anxiety levels in patients hospitalized with cardiovascular-related diseases and hypertension.Methods:A total of 221 patients hospitalized with cardiovascular-related diseases in the Fuwai Hospital were selected by a voluntary sampling method from September to December 2021. Participants were divided into hypertensive and non-hypertensive groups ( n=119 and n=102) based on the diagnosis of hypertension in their inpatient medical records. Anxiety levels were assessed using the Zung Self-Rating Anxiety Scale, and the levels of serum hs-CRP were estimated by automatic immunoanalyzer. Multivariate logistic regression was used to analyze the relationship between hs-CRP and anxiety. Results:In the hypertensive group, the risk of anxiety in patients with abnormal hs-CRP (>3 mg/L) was 4.239 times (95% CI: 1.569-11.748, P=0.005) higher than those in normal hs-CRP (≤3 mg/L). In turn, compared with patients without anxiety, those with anxiety had 3.878 times greater probability of experiencing abnormal hs-CRP (95% CI: 1.495-10.062, P=0.005), while those with mild anxiety and moderate to severe anxiety had 4.525 times (95% CI: 1.392-14.714, P=0.012) and 3.286 times (95% CI: 0.911-11.357, P=0.070) greater odds of experiencing abnormal hs-CRP, respectively. No similar significant association was seen in the non-hypertensive group. Conclusion:There is an interrelationship between elevated hs-CRP and anxiety in hospitalized patients with cardiovascular-related diseases and hypertension.

Self-sampling is a method by which the subject collects the own specimens for disease detection. It has the advantages of strong privacy, convenient and simple operation, free time and place, etc. It can improve the compliance of people in remote areas, affected by traditional concepts, limited by working hours and underdeveloped transportation and medical treatment to participate in disease detection and screening. With the development of "Internet+health care" and "Internet+nursing service", home-based self-sampling testing will become a developing situation for disease detection and screening. Human immunodeficiency virus and Human papillomavirus infection bring a heavy burden to individuals and society. In the absence of effective and widespread primary prevention, secondary prevention, namely "early detection, early diagnosis and early treatment" is an effective measure to control the adverse consequences. At present, there are many researches on HPV and HIV self-sampling test, whose test results are highly reliable and highly accepted in the population, and is of great significance for improving the coverage rate of cervical cancer screening and the diagnosis rate of HIV carriers.

ObjectiveTo evaluate the safety and comfort of hepatic artery infusion chemotherapy （HAIC） via distal transradial access （dTRA） in patients with liver cancer. MethodsPatients with advanced liver cancer who received HAIC via dTRA or transfemoral access （TFA） at the Department of Interventional Radiology， the First Affiliated Hospital of Sun Yat-sen University， were enrolled. The patients underwent dTRA or TFA for onetime and crossed-over subsequently. The patients received HAIC using FOLFOX4 regimen. Postcatheterization questionaire was used to compare the effects of the two vessel accesses on patients’ quality of life. Procedure-related adverse events were also recorded. ResultsAmong the 18 cases enrolled for HAIC， 9 underwent crossover from dTRA to TFA and the the remaining 9 from TFA to dTRA. During HAIC via dTRA， we only found grade 1 or grade 2 procedure-related adverse events such as 2 access site hematoma， 3 persistent pain at access site and 1 left palm numbness. No grade 3 or grade 4 procedure-related adverse event was found. Post dTRA ultrasound revealed no proximal radial artery occlusion. Significant difference in catheterization time between dTRA and TFA accesses was found （4 min vs. 3 min， P < 0.05）. All comfort scores were higher with dTRA as compared to TFA and patients preferred dTRA （7.89 vs. 2.72， P < 0.001）. The compression time for dTRA access was significantly shorter than TFA access （2 h vs. 7 h， P < 0.05）. ConclusionsdTRA approach is safe and tolerable， which is beneficial to improve the quality of life and comfort of patients with liver cancer when undergoing HAIC.
