Objective: To analyze the association and dose response relationship between physical activity and inflammatory markers in college students, so as to provide a reference for promoting cardiometabolic health in college students. Methods: A cluster random sampling method was used to select 747 college students from two universities in Hefei, Anhui Province and Shangrao, Jiangxi Province from April to May 2019. Physical activity was assessed by using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), and peripheral blood was collected to detect plasma inflammatory factor levels [including hypersensitive C reactive protein (hsCRP), interleukin-10 (IL-10), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)]. The differences between the groups were compared by using the χ 2 test and the Kruskal-Wallis rank sum test, and the association between physical activity and inflammatory markers was analyzed by using the Generalized Linear Model. The dose response relationship between physical activity and inflammatory markers was analyzed using the Restricted Cubic Spline Model. Results: The proportions of low physical activity, moderate physical activity, and high physical activity groups of college students were 15.9%, 53.7% and 30.4%, respectively. The levels of hsCRP, IL-10, IL-1β, IL-6 and TNF-α in the high physical activity group were 0.38(0.21, 1.10)mg/L, 70.74(47.90, 116.43)pg/mL, 1.75(1.21, 2.64)pg/mL, 4.33(2.93, 6.82) pg/mL , 5.27(3.89, 7.30)pg/mL,the levels in the low physical activity group were 0.80(0.31, 1.30)mg/L, 73.88 (47.90, 124.24)pg/mL, 1.88(1.42, 2.81) pg/mL, 4.82 (3.64, 6.67) pg/mL, 5.63 (4.34, 7.62)pg/mL, the levels in the moderate physical activity group were 0.63(0.25, 1.30)mg/L, 89.78(58.21, 127.65)pg/mL, 2.21(1.59, 3.27)pg/mL, 5.15( 3.72 , 7.72)pg/mL, 5.87( 4.63 , 8.00)g/mL, and the differences were statistically significant ( H=10.66, 11.38, 27.79, 14.13, 9.44, P <0.05). After adjusting for variables such as gender, body mass index, smoking, alcohol consumption and health status, the results of Generalized Linear Model showed that compared with the high physical activity group, the low physical activity group ( OR=2.20, 95%CI = 1.46- 3.31) and the moderate physical activity group ( OR=1.65, 95%CI =1.22-2.25) were more likely to have high levels of hsCRP, and the moderate physical activity group was more likely to have high levels of IL-1β ( OR=1.85, 95%CI =1.36-2.51), IL-6 ( OR=1.44, 95%CI =1.06-1.96), and TNF-α ( OR=1.43, 95%CI =1.05-1.94) ( P <0.05). The Restricted Cubic Spline Model showed that there was no linear dose response relationship between the time of moderate to vigorous physical activity weekly and IL-10, IL-6, II-1β, and TNF-α ( P <0.05). Conclusion There is an association between physical activity and inflammation in college students, and moderate to high intensity per week could reduce inflammation levels to promote cardiometabolic health in college students.

ObjectiveTo investigate the main risk factors for liver cirrhosis in chronic hepatitis B （CHB） patients with high metabolic risk， to establish a noninvasive predictive model， and to compare the diagnostic efficiency of this model and other models including fibrosis-4 （FIB-4）， aspartate aminotransferase-to-platelet ratio index （APRI）， gamma-glutamyl transpeptidase-to-platelet ratio （GPR）， and Forns index. MethodsA total of 527 CHB patients with high metabolic risks who were admitted to The Second Affiliated Hospital of Guangxi Medical University from September 1， 2017 to October 31， 2022 were enrolled as subjects， and they were randomly divided into modeling group with 368 patients and validation group with 159 patients at a ratio of 7∶3. The LASSO regression analysis and the multivariate Logistic regression analysis were performed for the modeling group to identify independent risk factors， and a nomogram model was established. The receiver operating characteristic （ROC） curve， the calibration curve， and the decision curve analysis were used to validate the nomogram prediction model in the modeling group and the validation group and assess its discriminatory ability， calibration， and clinical practicability. The Delong test was used to compare the area under the ROC curve （AUC） of the nomogram prediction model and other models. ResultsThe multivariate Logistic regression analysis showed that prealbumin （odds ratio ［OR］ = 0.993， 95% confidence interval ［CI］： 0.988 — 0.999， P= 0.019）， thrombin time （OR=1.182， 95% CI： 1.006 — 1.385， P=0.047）， log₁₀ total bilirubin （TBil） （OR=1.710， 95%CI： 1.239 — 2.419， P=0.001）， and log₁₀ alpha-fetoprotein （AFP） （OR=1.327， 95%CI： 1.052 — 1.683， P=0.018） were independent influencing factors for liver cirrhosis in CHB patients with high metabolic risks. A nomogram model for risk prediction was established based on the multivariate analysis， which had an AUC of 0.837 （95%CI： 0.788 — 0.888）， a specificity of 73.5%， and a sensitivity of 84.7%， as well as a significantly higher diagnostic efficiency than the models of FIB-4 （0.739）， APRI （0.802）， GPR （0.800）， and Forns index （0.709） （Z=2.815， 2.271， 1.989， and 2.722， P=0.005， 0.017， 0.045， and 0.006）. ConclusionThe nomogram model established based on prealbumin， thrombin time， log₁₀ TBil， and log₁₀ AFP has a certain clinical application value.

Objective To compare the postoperative enhanced recovery outcomes of lobectomy performed under non-intubated video-assisted thoracic surgery (NIVATS) versus intubated video-assisted thoracic surgery (IVATS). Methods Computerized searches were performed in the following databases: China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Information, China Biomedical Literature Database (CBMdisc), Web of Science, Clinicaltrials.gov, The Cochrane Library, EMbase, and PubMed. We collected randomized controlled trials (RCTs) and observational studies comparing NIVATS and IVATS. The search period extended from the inception of each database to April 1, 2023. Two independent researchers screened the literature and assessed study quality. Results A total of 14 studies were included, comprising 4 RCTs, 7 retrospective cohort studies, and 3 propensity score matching studies, involving 1 840 patients. Meta-analysis results indicated that, compared to IVATS, NIVATS was associated with significantly shorter operative time [MD=–13.39, 95%CI (–20.16, –6.62), P<0.001], shorter length of hospital stay [MD=–0.81, 95%CI (–1.39, –0.22), P=0.005], shorter chest tube duration [MD=–0.73, 95%CI (–1.36, –0.10), P=0.02], shorter postoperative anesthesia recovery time [MD=–20.34, 95%CI (–26.83, –13.84), P<0.001], and shorter time to oral intake after surgery [MD=–5.68, 95%CI (–7.63, –3.73), P<0.001]. Furthermore, NIVATS showed a lower incidence of postoperative airway complications [OR=0.49, 95%CI (0.34, 0.71), P<0.001] and less total chest tube drainage volume [MD=–251.11, 95%CI (–398.25, –103.98), P<0.001], all contributing to significantly accelerated postoperative enhanced recovery for patients. Conclusion NIVATS is a safe and technically feasible anesthesia method in thoracoscopic lobectomy, which can to some extent replace IVATS.

OBJECTIVE To investigate the effects of the peroxisome proliferator-activated receptors δ （PPARδ） agonist GW501516 on the injury of pulmonary artery endothelial cells （PAECs） induced by hypoxia and its mechanism. METHODS The cytotoxic effects of GW501516 were observed by detecting the relative survival rate of PAECs； the protein expression of PPARδ was determined by Western blot assay. The cellular model of PAECs injury was established under hypoxic conditions； using antioxidant N-acetylcysteine （NAC） as positive control， the effects of GW501516 on cell injury and reactive oxygen species （ROS） production were investigated by detecting cell apoptotic rate， cell viability， lactate dehydrogenase （LDH） activity and ROS levels. Using nuclear factor erythroid 2-related factor 2（Nrf2） activator dimethyl fumarate （DMF） as positive control， PAECs were incubated with GW501516 and/or Nrf2 inhibitor ML385 under hypoxic conditions； the mechanism of GW501516 on PAECs injury induced by hypoxia was investigated by detecting cell injury （cell apoptosis， cell viability， LDH activity）， the levels of superoxide dismutase （SOD）， glutathione peroxidase （GPx）， catalase （CAT）， malondialdehyde （MDA） and ROS， the expressions of Nrf2， heme oxygenase-1 （HO-1） and cleaved-caspase-3 （C-caspase-3） protein. RESULTS The results demonstrated that hypoxia inhibited the protein expression of PPARδ （P＜0.05）， while GW501516 promoted the protein expression of PPARδ in hypoxia- exposed PAECs without obvious cytotoxic effects. GW501516 inhibited the apoptosis of PAECs， improved cell viability， and reduced LDH activity and ROS levels. GW501516 could up-regulate the protein expression of HO-1 in PAECs and the levels of SOD， GPx and CAT， while down-regulated the levels of MDA and ROS by activating the Nrf2 pathway （P＜0.05）； but Nrf2 inhibitor ML385 could reverse the above effects of GW501516 （P＜0.05）. GW501516 exerted similar effects to Nrf2 activator DMF in down-regulating the expression of C-caspase-3 and inhibiting the injury of PAECs under conditions of hypoxia （P＜0.05）. Moreover， Nrf2 inhibitor ML385 reversed the 163.com inhibition effects of GW501516 on PAECs injury （P＜0.05）. CONCLUSIONS GW501516 can relieve the hypoxia-induced injury of PAECs via the inhibition of oxidative stress， the mechanism of which may be associated with activating Nrf2.

Objective: To describe the association of different sleep characteristics and cardiometabolic risk among college students, so as to provide reference for health promotion of college students. Methods: By random cluster sampling method, a questionnaire survey and physical examination including blood pressure, waist circumference and blood lipid indicators, which were conducted in April and May of 2019 among a total of 1 179 college students from the first grade in two universities in Hefei City of Anhui Province and Shangrao City of Jiangxi Province. A total of 729 college students with valid questionnaires were included into analysis. The Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were used to investigate sleep behavior, and the Morning And Evening Questionnaire-5 (MEQ-5) was used to investigate sleep characteristics. The cardiometabolic risk score was derived using the sum of the standardized sex specific Z scores of waist circumference, mean arterial pressure, HDL cholesterol (multiplied by -1), triglycerides, and insulin resistance index. The rank sum tests were used to compare differences in cardiometabolic risk scores across demographic characteristics. Generalized linear models were used to compare the association of different sleep characteristics with cardiometabolic risk scores among college students. Results: The average cardiovascular metabolic risk score of college students was -0.32(-2.03, 1.58). There were statistically significant differences in cardiovascular metabolic risk scores among college students in variables such as smoking, health status, and physical activity levels ( t/F=-3.41, 12.88, 51.07, P <0.01). The results of the generalized linear model showed that nighttime preference ( B=1.89, 95%CI =1.02-3.49), insomnia symptoms ( B=3.25, 95%CI =1.79-5.90), and short or long sleep duration ( B=1.92, 95%CI =1.21-3.05) were positively correlated with the cardiovascular metabolic risk score of college students ( P <0.05). Conclusions Poor sleep patterns among college students are positively correlated with the risk of cardiovascular metabolism. The sleep behavior of college students should be actively changed to reduce the risk of cardiovascular disease.

AIM: To investigate the effects of 0.01% atropine eye drops on macular blood flow density and retinal thickness in children with different degrees of myopia. METHODS: This was a prospective case-control study. Sixty-four patients (112 eyes) diagnosed with myopia for the first time with 0.01% atropine eye drops before and 6 months after medication were investigated with the uncorrected distance visual acuity (UCVA), axial length (AL), spherical equivalent (SE), macular ganglion cell-inner plexiform layer thicknes (mGCIPL) using slit lamp examination and optical coherence tomography (OCT), vascular density in the macular area and the area of the avascular in the fovea using optical coherence tomography angiography (OCTA) . Changes in various indicators before and after medication were compared. RESULTS: Compared with before medication, the AL of the three groups of myopia patients increased significantly (P<0.01), the difference in low to moderate myopia group was significantly smaller than that in high myopia group. Compared with before medication, SE increased in all three groups of myopia patients, yet there was no statistically significant difference in the low - grade myopia group (P>0.05). The difference was statistically significant between the moderate myopia group and the high myopia group (P< 0.01). Compared with before medication, there was no change in intraocular pressure (IOP) among the three groups of myopic patients (P>0.05). After 6 months of medication, the central circle macular vessel density (cCVD) increased in the low myopia group and moderate myopia group (P<0.01), there was no statistically significant difference in the high myopia group (P>0.05). Before and after medication, there was no significant difference in outer circle macular vessel density (oCVD), inner circle macular vessel density (iCVD), and whole circle macular vessel density (wCVD) among the three myopia groups (P>0.05). The increase in mGCIPL was statistically significant in the low myopia group (P<0.01), but there was no statistically significant difference in the moderate myopia and high myopia groups (P>0.05). There was no significant difference in foveal avascular zone (FAZ) among the three myopia groups before and after medication (P>0.05). There was no correlation between CVD, AL, and SE in the three myopia groups (P>0.01). There was a low correlation between CVD and mGCIPL in the low myopia group (r=0.442, P<0.05), there was no correlation between CVD and mGCIPL in the moderate myopia and high myopia groups (P >0.01). CONCLUSION: 0.01% atropine can significantly reduce the rate of axial and refractive growth in children with low to moderate myopia, increase the density of central macular vessels, and increase the thickness of mGCIPL in children with low to moderate myopia.

Objective:To compare the mid-term clinical effects of AngioJet rheolytic thrombectomy assisted catheter-directed thrombolysis (ART+CDT) with catheter-directed thrombolysis (CDT) in the treatment of acute deep venous thrombosis of lower extremities.Methods:Ninety-one patients admitted to the Department from Jan 2016 to Dec 2017 were placed with inferior vena cava filters and divided into ART+CDT group (30 cases)and CDT group (61 cases). Total urokinase dosge, thrombolytic time, operative cost, length of hospital stay, detumescence rate, thrombus clearance rate, cumulative patency rate of lower limb veins, Villalta score at 2 years and 5 years, thrombosis recurrence rate and chronic venous insufficiency quality of life questionnaire were compared between the two groups.Results:The success rate of surgery was 100% in both groups, there was no mortality. There were significant differences in the short-term postoperative outcomes between the two groups in terms of total dosage of urokinase, thrombolysis time, total cost of surgery, length of hospital stay, detumescence rate, venous patency scores before and after treatment, and venous patency rate (all P<0.05). For the mid- and long-term postoperative outcomes of 2 and 5 years, there were no significant differences in the incidence of PTS, recurrence rate of thrombus, chronic venous function scale, and cumulative patency rate at 2 years (all P>0.05). Conclusions:ART+CDT has a significant advantage over CDT alone in terms of early efficacy and early reopening of blood flow in patients. Both ART+CDT and CDT have a low incidence of PTS and a low recurrence rate of thrombus in the mid-term follow-up, and both have satisfactory performance in the mid- and long-term efficacy of interventional treatment of deep venous thrombosis of lower limbs.

OBJECTIVE To explore the effects of ADRB1 Arg389Gly polymorphisms on the efficacy of bisoprolol， thus providing some information for individualized drug therapy. METHODS A systematic search was conducted in PubMed， Embase， Cochrane Library， CBM， CNKI， and Wanfang Data to retrieve and find out all relevant literature about bisoprolol and ADRB1 Arg389Gly polymorphism from the inception to May 2023. The retrieved literature was screened and selected according to the inclusive and exclusive criteria， thereafter quality assessment was conducted. RevMan 5.4 software was utilized to perform the meta- analysis for the outcome index. RESULTS Overall 7 literature with 1 339 cases were included. Among them， 4 studies provided the changes in systolic blood pressure （SBP）， diastolic blood pressure （DBP） （ΔSBP and ΔDBP）； 4 involving the change （ΔLVEF） of left ventricular ejection fraction （LVEF）. Results of the study showed that there was no statistical significance in the improvement of blood pressure between wild-type group （AA） and mutation group （AG+GG） of ADRB1 Arg389Gly treated with bisoprolol {ΔSBP [SMD＝0.17，95%CI （－0.97，1.31）， P＝0.77]， ΔDBP [SMD＝－0.01，95%CI （－0.65，0.62）， P＝0.97]}； there was no statistical significance in the improvement of ΔLVEF [SMD＝－0.61， 95%CI （－2.74，1.53）， P＝0.58] between 2 groups. CONCLUSIONS ADRB1 Arg389Gly gene polymorphism has no significant influence on the improvement of SBP， DBP， and LVEF in cardiovascular patients who use bisoprolol.

Objective: To describe the prevalence and the association of sleep quality trajectory, social jetlag and comorbid symptoms of anxiety and depression among college students, in order to provide a theoretical basis for improving the comorbid symptoms of anxiety and depression in college students. Methods: A questionnaire survey was conducted among 1 135 college students from two universities in Shangrao, Jiangxi Province and Hefei, Anhui Province from April to May 2019, and were followed up once every one year for a total of three times, with a valid sample size of 1 034 individuals after matching with the baseline survey. A selfassessment questionnaire was used to investigate the social jetlag of college students, the Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire 9 (PHQ-9) were used to evaluate anxiety and depression symptoms, respectively, while the Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. College students with GAD-7 score ≥5 and PHQ-9 score ≥5 were defined as having comorbid anxiety and depression symptoms. Latent class growth model (LCGM) was employed to analyze the sleep quality trajectory of college students, and binary Logistic regression was used to analyze the relationship between social jetlag, sleep quality trajectory and comorbid symptoms of anxiety and depression. Results: The detection rate of comorbid symptoms of anxiety and depression among college students was 16.9%, and the detection rate of social jetlag ≥2 h was 13.8%. The sleep quality showed an overall improvement trend, and the two trajectories were good sleep quality (81.6%) and poor sleep quality (18.4%). Binary Logistic regression model showed that poor sleep quality and social jetlag ≥2 h were positively correlated with comorbid symptoms of anxiety and depression (OR=5.94, 1.84, P<0.05). Conclusions Poor sleep quality and social jetlag ≥2 h in college students increase the risk of comorbid symptoms of anxiety and depression. Early screening and intervention of sleep quality and reduction of social jetlag are crucial for enhancing the mental health of college students.
