Objective: To explore the associations of physical activity and sleep quality with anxiety and depressive symptoms in college students, in order to provide empirical support and theoretical guidance for mental health intervention among college students. Methods: From March to April 2023, 2 099 college students from universities in 6 different provinces were selected by a convenient sampling method. Physical activity, sleep quality, anxiety and depressive symptoms were evaluated by the International Physical Activity Questionnaire Short Form (IPAQSF), the Pittsburgh Sleep Quality Index (PSQI), the Center for Epidemiologic Studies Depression Scale (CESD) and the Anxiety SelfRating Scale (SAS), respectively. Descriptive statistics and Logistic regression models were used to analyze the data. Results: The reporting rates of lowintensity, moderateintensity, and highintensity physical activity among college students were 30.3%, 45.3%, and 24.4%, respectively. Moreover, among the participants, anxiety was detected in 21.6% and depressive symptoms in 39.9%, while 62.3% experienced poor sleep quality. Compared with males, females exhibited a lower proportion of highintensity physical activity (22.3% vs 42.8%), while reported higher proportions of moderateintensity (48.1% vs 40.8%) and lowintensity physical activity (29.5% vs 16.4%). Additionally, the proportion of females reporting poor sleep quality (65.0%) was higher than that of males (58.0%) (χ2=110.15, 10.70, P<0.05). The proportion of girls (43.8%) with depressive sypmtoms was higher than that of boys (33.9%) (χ2=20.48, P<0.05). Logistic regression analysis showed that high physical activity was negatively correlated with anxiety and depression (OR=0.45, 0.33), poor sleep quality was positively correlated with anxiety and depressive symptoms (OR=3.89, 3.94) (P<0.01).The interaction effect between high physical activity and good sleep quality was associated with the reduction of anxiety and depression among college students (OR=0.14, 0.08, P<0.01). Conclusions Physical activity and sleep quality are associated with anxiety and depressive symptoms among college students. The interventions for mental health problems such as depression and anxiety among college students should aim to improve physical activity and sleep quality.

Objective:To investigate the iodine nutritional status of pregnant women in Jilin Province and its correlation with the distribution characteristics of water iodine in external environment, providing a basis for scientific iodine supplementation and prevention of iodine deficiency disorders.Methods:A retrospective analysis was conducted on the iodine survey data of drinking water for residents in Jilin Province in 2017 and the monitoring data of iodine deficiency disorders in 2021. The water iodine, salt iodine, and urinary iodine level of pregnant women were analyzed.Results:In 8 866 water samples from 873 townships (streets, hereinafter referred to as townships) of 60 counties (cities, districts) in 9 cities (autonomous prefectures) throughout the province, the median of water iodine was 4.60 μg/L, ranging from 0.00 to 81.30 μg/L. Among them, there were 758 townships with a median water iodine < 10 μg/L, accounting for 86.83% (758/873); 107 townships with a water iodine of 10 - < 40 μg/L, accounting for 12.26% (107/873). The median salt iodine was 23.50 mg/kg in 6 000 household consumption salt samples. The iodized salt coverage rate, iodized salt qualified rate, and qualified iodized salt consumption rate were 99.50% (5 970/6 000), 97.30% (5 809/5 970), and 96.82% (5 809/6 000), respectively. The iodized salt coverage rate in 9 cities (autonomous prefectures) were > 95%, the iodized salt qualified rate and qualified iodized salt consumption rate were > 90%. The median urinary iodine in 6 000 pregnant women's urine samples was 169.05 μg/L. Except for Bayshan City, which was iodine-deficient, the other 8 cities (autonomous prefectures) were iodine-suitable. The results of correlation analysis showed that there was no correlation between the urinary iodine level of pregnant women and the distribution of water iodine in the external environmental at the municipal (autonomous prefecture) level ( r = 0.60, P = 0.089). Conclusions:Most townships in Jilin Province are iodine-deficient in the external environment, and there are no water-borne high iodine area. The iodized salt coverage rate, iodized salt qualified rate, and qualified iodized salt consumption rate all meet the national standards. The iodine nutrition of pregnant women is generally at a suitable level, but there are still some areas where pregnant women are iodine-deficient, and there is no correlation with the distribution of water iodine.

Total mesorectal excision (TME) has become the basic principle of surgical treat-ment for middle and low rectal cancer. Some of patients with ultra-low rectal cancer require under-going intersphincteric resection (ISR). Due to the limitation of the narrow pelvis, TME and ISR put forward higher requirements for the precise separation of the anatomical level and the protection of neurological function during the operation. At present, evaluation of the difficulty of surgery for middle and low rectal cancer is mainly based on the subjective judgment of chief surgeon, and there is no unified and objective scoring system or prediction model that can classify the difficulty of surgery for middle and low rectal cancer before surgery. The authors review relevant literatures and summarize the existing studies related to pelvic measurement for predicting the difficulty of surgery for middle and low rectal cancer, in order to provide significant guidance for the selection of surgical approach for patients with middle and low rectal cancer.

Objective:To investigate the clinical efficacy of high-frequency repetitive transcranial magnetic stimulation combined with electrical stimulation in patients with dysphagia after stroke.Methods:Seventy-two stroke patients with dysphagia who received treatment in The First Hospital of Jiaxing from February 2019 to February 2020 were included in this study. They were randomly assigned to receive either electrical stimulation (control group, n = 36) or high-frequency repetitive transcranial magnetic stimulation combined with electrical stimulation (observation group, n = 36) for 2 weeks. Changes in serum brain-derived neurotrophic factor, neuron-specific enolase, and vascular endothelial growth factor levels after treatment relative to before treatment were observed in each group. Scores of the swallowing function assessment scale, neurological deficit, and quality of life were compared between the control and observation groups. Results:After treatment, serum levels of brain-derived neurotrophic factor and vascular endothelial growth factor in the observation group were (7.98 ± 1.14) μg/L, (168.78 ± 10.28) ng/L, respectively, which were significantly higher than those in the control group [(5.80 ± 1.10) μg/L, (110.34 ± 10.47) ng/L, t = 8.26, 23.90, both P < 0.01]. Serum neuron-specific enolase level was significantly lower in the observation group than in the control group [(7.57 ± 1.17) μg/L vs. (10.66 ± 1.30) μg/L, t = 10.60, P < 0.001). The scores of swallowing function assessment scale and neurological deficits in the observation group were (2.47 ± 1.16) points and (7.03 ± 1.14) points, respectively, which were significantly lower than those in the control group [(5.75 ± 1.10) points, (9.66 ± 1.20) points, t = 12.31, 9.53, both P < 0.001]. Total effective rate [97.22% (35/36) vs. 77.78% (28/36)] and the score of swallowing quality of life questionnaire [(160.40 ± 8.32) points vs. (146.74 ± 8.10) points] were significantly higher in the observation group than in the control group ( χ2 = 4.57, P = 0.03, t = 7.25, P < 0.001). Conclusion:High-frequency repetitive transcranial magnetic stimulation combined with electrical stimulation can greatly improve neurological function and swallowing function of stroke patients with dysphagia. The combined therapy is of certain clinical value and innovation.

A fluorescent microsphere-based immunochromatographic strip test (FICT) was developed for the rapid, sensitive, and quantitative detection of porcine reproductive and respiratory syndrome virus (PRRSV) antibodies at the pen-side. The assay was based on the formation of a sandwich immune-complex (anti-pig IgG-PRRSV antibodies-NSP7/N), which was validated by a comparison with IDEXX-ELISA using 3325 clinical specimens. The diagnostic specificity, sensitivity, and accuracy of FICT were 97.28, 93.41, and 94.95%, respectively. FICT showed a good correlation with the virus neutralization assay. Overall, a promising pen-side diagnostic tool was developed for the rapid and quantitative detection of PRRSV antibodies within 15 min.

Objective:To investigate the correlation between serum uric acid level and non-alcoholic liver disease (NAFLD).Methods:A medical examination cohort of our hospital′s staff was constructed. From February 1, 2012 to January 29, 2013, a total of 3, 479 staff without NAFLD were selected as research subjects, and baseline data were collected through a questionnaire survey, physical examination, abdominal ultrasound examination, blood lipid, blood glucose, liver and kidney function, and other laboratory tests. From February 1, 2013 to December 31, 2018, the patients were followed up during the annual physical examination for six years. The serum uric acid level was used as the observation index and divided into four groups from A to D according to the quartile. With the occurrence of NAFLD as the outcome indicator; the four groups of uric acid as the observation indicator; and age, body mass index, hyperlipidemia, hyperglycemia, hypertension, creatinine, and alanine aminotrans ferase as confounding factors; four Cox regression analysis models were constructed to explore the relationship between groups of different blood uric acid levels and NAFLD. Stratified by gender, three Cox regression analysis models were constructed to investigate the relationship between blood uric acid level grouping and NAFLD between different genders.Results:The six-year cumulative incidence of NAFLD in groups A, B, C, and D was 1.2%, 3.1%, 4.9%, and 12%, respectively (χ 2=114.710, P<0.05). Among the female workers, the six-year cumulative incidence rates in groups A, B, C, and D were 1.0%, 2.9%, 4.1% and 10.9%, respectively (χ 2=71.241, P<0.05). The incidence risk of NAFLD in groups B, C, and D was 2.04 (1.01-4.11), 2.24 (1.13-4.44), and 3.89 (1.94-7.80) times that of group A, P<0.05, respectively. The incidence risk of NAFLD in groups B, C, and D was 2.21 (1.02-4.77), 2.39 (1.10-5.19), and 4.49 (1.99-10.15) times that of group A, all P<0.05, respectively. Conclusion:The risk of NAFLD increased with the increase of serum uric acid level, and this trend was mainly manifested in female employees.

Objective: To investigate the sexual function, urinary function and quality of life in patients of ulcerative colitis(UC) and familial adenomatous polyposis(FAP) after total proctocolectomy and ileal pouch anal anastomosis (IPAA). Methods: The clinical data of patients with UC and FAP undergoing IPAA at Zhongnan Hospital of Wuhan University from Jan 2006 to Sep 2018 were reviewed , postoperative sexual function, urinary function, and long-term quality of life were assessed. Results: There were 45 patients with median age of 35 years , median follow-up time of 31 months. 18 were UC, 27 were FAP, 5 did 1-stage surgery, 37 did 2-stage surgery, 3 for 3-stage surgery, 13 underwent open surgery, and 32 underwent laparoscopic surgery. 7 patients suffered sexual dysfunction after IPAA, and there was no statistical difference between male and female (P=0.992), UC and FAP (P=0.153), 1-stage , 2-stage , and 3-stage surgery (P=0.363) , with statistically significant difference between the open group and the laparoscopic group (P=0.025). 6 patients complicated with urinary dysfunction after IPAA , and there was no statistical difference between male and female (P=0.562), UC and FAP (P=0.325), 1-stage, 2-stage, and 3-stage surgery (P=0.286) , with statistically significant difference between the open group and the laparoscopic group (P=0.007). The Cleveland Global Quality of Life (CGQL) score after IPAA was 0.696±0.085. There were no statistical difference on CGQL scores in males and females (P=0.635), UC and FAP (P=0.664), 1-stage, 2-stage, and 3-stage (P>0.05), open group and laparoscopic group (P=0.205), postoperative long-term QOL was significantly associated only with age at the time of surgery (P=0.001). Conclusions Compared with open surgery, laparoscopic TPC-IPAA patients had better postoperative sexual function and urination function.

PurposeTo investigate whole-body magnetic resonance imaging in diagnosis of idiopathic inflammatory myopathy (IIM), and to guide clinical treatment.Materials and Methods Twenty-six patients clinically diagnosed IIM including 19 dermatomyositis and 7 polymyositis were analyzed retrospectively. Whole-body MRI was performed in all patients including whole-body coronal scan and axial scan of both sides of thigh. Short tau inversion recovery (STIR) sequences were used in the coronal scan and T1WI and fat-suppressed T2WI were performed in the axial scan. Ten healthy volunteers were recruited as control group. MRI findings were compared between the two groups.Results Whole body MRI showed that muscles were homogeneously low signal intensity in the control group. Imaging findings of the patients with IIM included muscle inflammation, fascitis, subcutaneous tissue edema, muscle atrophy and fatty infiltration. The most common distribution site of muscle inflammation of dermatomyositis patients was thigh (n=18), followed by gluteus (n=14), great psoas muscle (n=13), shoulder muscles (n=11), leg muscle (n=11), erector spinae (n=10) and neck muscles (n=9). Findings out of muscles included cavities in the both lungs, infarction in femurs and tibias, avascular necrosis of femoral head, adrenal mass and thyroid nodules. The most common distribution site of muscle inflammation of polymyositis was thigh (n=5), followed by gluteus (n=3), great psoas muscle (n=3), shoulder muscles (n=2), leg muscles (n=2), erector spinae (n=1) and neck muscles (n=1). Findings out of muscles included 1 case of infarction in femurs and tibias.Conclusion Whole-body MRI can not only comprehensively evaluate the activity of IIM but also detect complications such as bone infarction. It's a powerful tool for diagnosis, guiding treatment and monitoring of IIM.

Objective To explore the therapeutic effect of erythropoietin (EPO)combined oral iron in patients with chronic congestive heart failure( CHF)accompanied by anemia. MethodsNinety six patients with CHF accompanied by anemia, whom were consecutively hospitalized from January 2007 to December 2009, were enrolled into this study. They were randomly divided into treatment group accepted routine anti-heart failure therapy combined EPO and oral iron, and control group solely accepted routine anti-heart failure therapy. After 6 months follow up, the changes of hemoglobin ( Hb ), cardiac function classification, left ventricular ejection fraction(LVEF) ,6-minute walking distance,readmission rate of CHF and cardiac death were compared between two groups. ResultsCompared with those before therapy, we found significant improvements of hemoglobin level ( [ 120. 12 ± 10. 42 ] g/L vs [ 86.40 ± 14. 30 ] g/L, P ＜ 0. 01 ), cardiac function classification ( 2. 65 ± 0. 67 vs 3. 13 ±0. 61, P ＜ 0. 01 ), LVEF ( [ 37.21 ± 4. 96 ]％ vs [ 33. 92 ± 7. 28 ]％, P ＜ 0. 01 ), 6-minute walking distance ( [ 443.52 ± 97. 39 ] mvs [ 379. 15 ± 59. 34 ] m, P ＜ 0. 01 ) in treatment group after EPO combined oral iron administration. After 6 months follow up, we also found significant improvements of Hb level ( [ 120. 12 ±10. 42 ] g/L vs [ 86. 40 ± 14. 30 ] g/L, P ＜ 0. 01 ), cardiac function classification ( 2.65 ± 0. 67 vs 2. 98 ± 0. 81,P＜0.01),LVEF([37.21 ± 4.96]％ vs [34.67 ±4.10]％,P ＜ 0. 01),6-minute walking distance ( [443.52 ±97. 39 ] mvs [ 379. 15 ± 59. 34 ] m, P ＜ 0. 01 ) in the comparison between treatment and control group. The readmission rate of CHF fell significantly in treatment group compared to control (20. 83％ vs 39. 58％ ,P ＜ 0. 05 ). However, we found no significant difference in cardiac death rate ( 0％ vs 4. 17％, P ＞0. 05). ConclusionTreatment of EPO combined oral iron could significantly improve the cardiac function,increase exercise tolerance,lower the readmission rate of CHF in patients with chronic congestive heart failure (CHF)accompanied by anemia.

Objective To compare the efficacy of total pelvic floor reconstruction with mesh patch and vaginal hysterectomy with anterior and posterior vaginal wall repair for presby-pelvic floor dysfunction patients.Methods We randomly chose 92 pelvic floor dysfunction inpatients of our hospital from September 2007 to February 2009 and divided them into 2 groups:total pelvic floor reconstruction group(n=70) underwent total pelvic floor reconstruction with mesh patch[12 patients of this group complicated with stress incontinence,4 patients received tension free vaginal tape-obturator(TVT-O) simultaneously];control group(n=22) received vaginal hysterectomy with anterior and posterior vaginal wall repair(3 patients of this group complicated with stress incontinence).A follow-up for 3 to 18 months after the surgery were taken in all the patients.Results In total pelvic floor reconstruction group,no recidivate case was found and the FOP scores and cure rate were 0 and 100% respectively.In control group,there were 7 recidivate cases,all of who were primary vagina anterior wall bulge patients.The cure rate of control group was 68%;For the patients complicated with stress incontinence,they were all cured by TVT-0 or by ascending the front patch in total pelvic floor reconstruction group,but 1 case was as before operation and 2 cases were even worse in control group.Conclusion Total pelvic floor reconstruction with vicarious materials had a definite efficacy for presby-pelvic floor dysfunction.
