ObjectivesTo evaluate the effects of physical exercises on the vision of students in China.MethodsTrials of the effects of physical exercises on students' vision were retrieved in databases of CNKI, WanFang Data, VIP, Web of Science, EBSCO, PubMed and The Cochrane Library from inception to September 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was carried out with RevMan 5.3 and Stata 13.0 software.ResultsA total of 8 studies including 681 students in the experimental group and 679 in the control group were included. The results of meta-analysis showed that physical exercises were beneficial to improving students' vision (SMD=1.02, 95%CI 0.90 to 1.13, P<0.000 01). The results of subgroup analysis showed that physical exercises in the elementary school students group (SMD=1.361, 95%CI 0.873 to 1.850, P<0.000 01), long period (>24 weeks) (SMD=1.502, 95%CI 0.984 to 2.019, P<0.000 01), medium frequency (3 times/week) (SMD=1.631, 95%CI 1.022 to 2.240, P<0.000 01), and short time (<90 min) (SMD=1.410, 95%CI 0.758 to 2.062, P<0.000 01) had superior results.ConclusionsPhysical exercises have beneficial effects on improving vision. Limited by quantity and quality of subjects, the above conclusions requires verification by more high-quality studies.
Objective To explore the risk factors for new-onset atrial fibrillation (POAF) after off-pump coronary artery bypass grafting (OPCAB) alone. Methods A retrospective analysis was conducted on the clinical data of patients who underwent OPCAB in the Department of Cardiac Surgery Ward No.1 of Zhengzhou Seventh People’s Hospital from January 2020 to January 2024. Patients were categorized into POAF and non-POAF groups based on the occurrence of POAF. The clinical data of both groups were analyzed. Parameters underwent single-factor analysis, and variables with P≤0.05 in single-factor analysis were further analyzed through binary logistic regression to identify independent risk factors. Results A total of 496 patients were included. There were 312 males and 184 females, with age ranging from 50 to 78 years. There were 148 patients in the POAF group and 348 patients in the non-POAF group. The incidence of POAF after isolated OPCAB surgery was 29.8%. Results of univariate analysis showed that there was statistical difference in the incidence of diabetes (P=0.012), >75% stenosis of the left circumflex artery (LCX) (P=0.036), shock (P<0.001), graded left ventricular diastolic function (P<0.001), left ventricular ejection fraction (P<0.001), age (P<0.001), preoperative resting heart rate (P<0.001), left atrial diameter (P<0.001), E/A ratio (P<0.001), postoperative K+ concentration (P<0.001), and postoperative Mg2+ concentration (P<0.001). Binary logistic regression multifactor analysis revealed that age (OR=1.436, 95%CI 1.094 to 1.884, P=0.009), diabetes (OR=2.032, 95%CI 1.094 to 1.884, P=0.043), preoperative resting heart rate (OR=1.008, 95%CI 1.001 to 0.018, P=0.018), left atrial diameter (OR=4.409, 95%CI 1.711 to 11.359, P=0.002), E/A ratio (OR=1.713, 95%CI 1.115 to 2.633, P=0.014). The occurrence of POAF significantly prolonged mechanical ventilation time and ICU stay (both P＜0.001). Conclusion Age, diabetes, left atrial diameter, EA ratio, and preoperative resting heart rate are potential independent risk factors for POAF following OPCAB surgery. Additionally, the occurrence of POAF post-surgery can lead to prolonged mechanical ventilation and extended stay in the intensive care unit.
Objective To summarize the updates of diagnosis and differential diagnosis for hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) for providing evidences for early diagnosis and treatment of PVTT patients. Methods The related literatures on diagnosis and differential diagnosis for HCC with PVTT in recent years were collected and reviewed. Results The serious complications and tumor metastasis are attributed to the PVTT, then it is necessary to make diagnosis accurately according to clinical symptoms, hematological and imaging examinations. The differential diagnosis of PVTT and portal vein thrombosis, portal sponge degeneration and hepatic arteriovenous shunt diseases should be carried out. Conclusions The diagnosis and differential diagnosis of PVTT cannot rely on a single method, and it requires a comprehensive judgment of various diagnostic methods. More accurate and specific diagnostic methods are needed.
ObjectiveTo evaluate the value of real-time indocyanine green fluorescence imaging navigation (ICG-FIN) in laparoscopic rectal cancer surgery. MethodsThe patients who adopted ICG-FIN during laparoscopic rectal cancer surgery in the Department of Anorectal Surgery of Xuzhou Central Hospital from April 2022 to June 2023 according to the inclusion and exclusion criteria (ICG-FIN group) were collected, meanwhile matching (1∶1) of patients who did not adopt ICG-FIN during laparoscopic surgery from January 2021 to May 2022 (control group). The general data, surgical conditions, intraoperative and postoperative outcomes between the two groups were compared. ResultsThere were 62 patients in the ICG-FIN group and 62 patients in the control group. There were no statistical differences in the gender, age, body mass index, comorbidities, and so on between the two groups (P>0.05). The tumor localization, lymph node tracing, fluorescence imaging of the intended resection of intestinal tract and anastomotic site were observed in the ICG-FIN group. Seven patients (11.3%) had changed in the intended resection of intestinal anastomotic line during surgery, while there were no changes of the surgical plan in the control group. There were no statistical differences (P>0.05) in terms of surgical method, operative time, intraoperative bleeding, proportion of ileostomy, time of the first postoperative exhaust, postoperative hospital stay, and incidence of short-term complications between the two groups. Compared with the control group, the incidence of anastomotic leakage was lower (P=0.012), and the number of lymph nodes cleaned was more (P=0.016) in the ICG-FIN group. However, there was no statistical difference in the number of positive lymph nodes detected between the two groups (P=0.343). ConclusionsAccording to the results of this study, ICG-FIN is a reliable and effective method during laparoscopic rectal cancer surgery, which can accurately localize tumor, trace and guide lymph node dissection. Real-time evaluation of intestinal blood flow perfusion is of great practical value in reducing anastomotic leakage.
