ObjectiveTo investigate the effect of Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma on ferroptosis in the rat model of myocardial infarction and further elucidate its role in myocardial remodeling. MethodsThe rat model of myocardial infarction was established by ligation of the left anterior descending coronary artery. The 50 successfully modeled rats were randomly divided into model group， ferroptosis inhibitor group （2 mg·kg^-1）， enalapril group （2.1 mg·kg^-1）， and low- and high-dose （4 g·kg^-1 and 8 g·kg^-1， respectively） Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma， with 10 rats in each group. The rat model of myocardial infarction was established by ligation of the left anterior descending coronary artery. After 4 weeks of treatment， echocardiography was used to assess the cardiac structure and function. Hematoxylin-eosin （HE） staining and Masson staining were employed to observe pathological morphology and fibrosis of the myocardial tissue. Serum levels of N-terminal pro-B-type natriuretic peptide （NT-proBNP）， transforming growth factor-β （TGF-β）， and myosin heavy chain-β （MHC-β） were measured by enzyme-linked immunosorbent assay （ELISA）. Prussian blue staining was performed to detect myocardial iron deposition. The myocardial mitochondrial structure was observed by transmission electron microscopy. Levels of malondialdehyde （MDA） and glutathione （GSH） in the myocardial tissue were determined by lipid peroxidation assay kits. Immunofluorescence assay was conducted to observe the fluorescence intensity of nuclear factor E₂-related factor 2 （Nrf2） in the myocardial tissue. Western blot analysis was performed to evaluate the expression levels of proteins in the Nrf2/solute carrier family 7 member 11 （SLC7A11）/glutathione peroxidase 4 （GPX4） pathway. ResultsCompared with the sham group， the model group showed increased left ventricular end-diastolic diameter （LVEDD）， left ventricular end-systolic diameter （LVESD）， and serum levels of NT-proBNP， TGF-β， and MHC-β （P<0.01）， decreased left ventricular ejection fraction （LVEF） and left ventricular fractional shortening （LVFS） （P<0.01）， disarrangement of myocardial cells， inflammatory cell infiltration， severe myocardial fibrosis， increased myocardial iron deposition， and irregular mitochondrial morphology with vacuolation. Furthermore， the modeling led to increased MDA （P<0.01）， decreased GSH （P<0.01）， diminished Nrf2 fluorescence intensity in the myocardial tissue， and downregulated expression levels of Nrf2， SLC7A11， and GPX4 （P<0.01）. Compared with the model group， Gardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma reduced the LVEDD， LVESD， and serum levels of NT-proBNP， TGF-β， and MHC-β （P<0.05， P<0.01）， increased the LVEF and LVFS （P<0.05， P<0.01）， alleviated pathological changes such as myocardial cell disarrangement， inflammatory cell infiltration， myocardial fibrosis， and iron deposition， lowered the level of MDA （P<0.05， P<0.01）， raised the level of GSH （P<0.05， P<0.01）， improved the mitochondrial morphology and reduced vacuolation in the myocardial tissue， enhanced Nrf2 fluorescence intensity， and upregulated the expression levels of Nrf2， SLC7A11， and GPX4 （P<0.05， P<0.01） in the rat model of myocardial infarction. ConclusionGardeniae Fructus-Salviae Miltiorrhizae Radix et Rhizoma alleviates pathological damage and myocardial remodeling in the rat model of myocardial infarction by inhibiting ferroptosis， the mechanism of which is related to the activation of Nrf2/SLC7A11/GPX4 signaling pathway.

Objective: To analyze the changes in classroom lighting environment of schools in Suzhou and their impact on refractive progression among primary and secondary school students, so as to provide the basis for accurate provention and control of myopia. Methods: A baseline investigation was conducted in October 2022 by using a stratified cluster random sampling method to recruit primary and secondary school students from Suzhou. A follow up visit was performed in October 2023. A total of 12 302 students and 360 classrooms that participated in both surveys were included analysis. The visual acuity progression over one year and classroom lighting conditions were assessed. Group comparisons were performed by using the Wilcoxon or Kruskal-Wallis rank-sum, and Chi-square tests. Multivariate Logistic regression was employed to identify the major factors influencing refractive changes. Results: The compliance rate of average illuminance on classroom blackboard surface increased from 72.22% to 75.28%, while the compliance rate of average illuminance on desks decreased from 89.44% to 87.22%, the overall myopia rate among students rose from 59.63% to 66.99% from 2022 to 2023. The average annual progression of equivalent spherical power(SE) in the right eye of students was -0.25(-0.75,0.06)D. Significant statistical differences were observed in the annual mean changes across different school levels, regions, baseline refractive statuses, and classroom lighting environment change groups ( Z/H =316.59, -8.27, 38.80 , 51.01, all P <0.05). Multivariate Logistic regression analysis showed that pre myopia, low myopia, junior high school, senior high school, vocational high school, and improved classroom lighting environment were protective factors of reducing the risk of rapid progression in refractive error ( OR =0.58, 0.69, 0.81, 0.50, 0.28, 0.82, all P <0.05). Conversely, female students and rural students had higher risks of rapid myopia progression ( OR =1.09, 1.42, both P <0.05). Conclusions Over one year follow up, the complance rate of classroom lighting indicators in Suzhou remaines stable, while students refractive status shows a trend toward myopia. Improving classroom lighting environment can reduce the risk of rapid myopia progression.

The control strategy of rehabilitation robots should not only adapt to patients with different levels of motor function but also encourage patients to participate voluntarily in rehabilitation training.However,existing control strategies usually consider only one of these aspects.This study proposes a voluntary and adaptive control strategy that solves both questions.Firstly,the controller switched to the corresponding working modes(including challenge,free,assistant,and robot-dominant modes)based on the trajectory tracking error of human-robot cooperative movement.To encourage patient participation,a musculoskeletal model was used to estimate the patient's active torque.The robot's output torque was designed as the product of the active torque and a coefficient,with the coefficient adaptively changing according to the working mode.Experiments were conducted on two healthy subjects and four hemiplegic patients using an ankle rehabilitation robot.The results showed that this controller not only provided adaptive the robot's output torque based on the movement performance of patients but also encouraged patients to complete movement tasks themselves.Therefore,the control strategy has high application value in the field of rehabilitation.

Objective To compare the cost-effectiveness of non-intubated general anesthesia with conventional general anesthesia for thoracoscopic bulla resection. Methods Sixty patients scheduled for elective thoracoscopic bulla resection, were divided into two groups (30 each) using a random number table: the conventional general anesthesia group (T group) and the non-intubated general anesthesia group (NT group). Patients in group T were induced with conventional general anesthetic, single-lung ventilated after intubation with double-lumen bronchial catheters. Patients in group NT were induced with general anesthesia combined nerve block, and spontaneous breathings were retained. The results of blood gas analysis, anesthesia time, operation time, intraoperative blood loss, time for orientation recovery and modified Aldrete score ≥ 9 minutes were recorded. The intraoperative and postoperative complications, postoperative hospital stay time, VAS and PC A scores 48 h after operation were recorded. Calculate the cost of anesthesia and the total cost of hospitalization. Results Compared with T group, NT group had lower pH value and higher PCO2 at 30 min before and after the thoracic closure, oxygenation index in the NT group increased at 30 min after the thoracic closure (P < 0.05). Compared with T group, anesthesia time, time for orientation recovery and modified Aldrete score ≥ 9 minutes, incidence of postoperative sore throat, postoperative hospital stay time, VAS scores at 6, 12 h and PC A at 48 h after the operation, anesthesia costs, and total hospitalization costs in the NT group were all reduced (P < 0.05). Conclusions Fully considering the safety, compared with the traditional tracheal intubation general anesthesia, non-intubation general anesthesia can not only promote postoperative outcomes but also improve the cost-effectiveness in the patients undergoing thoracoscopic bulla resection.

Objective To explore the influence of family-integrated transition care on the daily living ability of discharged patients with stroke.Methods Seventy-eight patients with stroke who were admitted to Renmin Hospital of Wuhan University from May 2016 to October 2017 were selected by convenience sampling and were divided into a control group and a family-integrated transition care group (hereinafter referred to as transition care group).The patients in the control group received routine neurological health education,while those in the transition care group received a family-integrated transition care intervention in addition to routine neurological health education.The family-integrated transition care included team building,skills training for family members,family-integrated guidance for discharged patients,and regular visits.The scores of the modified Barthel index were compared between the two groups of patients at discharge,three months after intervention,and six months after intervention.Results Among the 71 patients that were finally included,35 cases were included in the control group,of which 17 cases were men (49％),18 cases were women (51％),and their mean age was (70.1±3.7) years;the transition care group comprised 36 cases,of which 18 cases were men (50％),18 cases were women (50％),and their mean age was (69.8±4.5) years.The baseline scores of the control group and transition care group on the day of discharge were (49.1 ± 7.5) and (49.7 ± 7.9),respectively,with no significant difference (P＞0.05).In terms of time effects,the scores of the patients in the two groups had statistically significantly improved at six months after discharge (P＜0.05).In the group comparison,the scores of the patients in the transition care group after the intervention were significantly higher compared to the scores of those in the control group (P＜0.05).In terms of time and inter-group effects,there was an interaction (P＜0.05),and therefore,the influence of time effects was excluded and the same timepoint was compared between the two groups.The scores at three months (63.9±8.8) and six months (76.9± 10.1) in the transition care group were higher than those in the control group (58.1 ±8.1 and 66.0 ±9.3,respectively).The difference was statistically significant (P ＜ 0.05).Conclusion Family-integrated transition care can effectively improve daily living ability and isworthy of promoting.

Objective To investigate feasibility of bowel preparation for colonoscopy in endoscopic ambulatory surgery ward. Methods A total of 352 patients at endoscopic ambulatory surgery ward receiving colonoscopy at Zhongshan Hospital, Fudan University from May 25, 2018 to July 13, 2018 were surveyed by questionnaires. Data of 344 patients, including patient demographics, bowel preparation information and Boston bowel preparation scores and subjective perception of patients were analyzed. Data of 8 others were excluded because they did not complete colonoscopy for the first time due to failure of bowel preparation. Chi-square test and logistic regression analysis were conducted to analyze the quality of bowel preparation and its influencing factors. Results A total of 18. 0％( 62/344) of bowel preparations were inadequate. Morning colonoscopy ( P = 0. 005, OR = 2. 505, 95％CI:1. 312-4. 781 ) and yellow residual last stool before colonoscopy (P=0. 045,OR=0. 475,95％CI:0. 230-0. 982) were independent risk factors for inadequate bowel preparation. Patients' tolerance was 88. 1％(303/344), satisfaction was 77. 9％(268/344), and 54. 9％(189/344) were willing to be hospitalized in ambulatory surgery ward again if necessary. Conclusion Bowel preparation before colonoscopy in endoscopic ambulatory surgery ward is feasible but not optimal.

Objective To investigate the expression and significance of FBXW7 and ENO1 in ovarian serous adenocarcinoma of different grades. Methods Immunohistochemistry was used to study the expression of FBXW7 and ENO1 in 60 cases of ovarian serous adenocarcinoma. The relationship between FBXW7 and ENO1 proteins and the prognosis of ovarian serous adenocarcinoma was analyzed. Results The positive rate of FBXW7 expression was 22. 5％ ( 9/40) in 40 cases of ovarian high grade adenocarcinoma and 10 cases in 15 cases of normal oviduct. The positive rate of FBXW7 expression was 66. 7％ ( 10/15) ,and the difference was statistically significant ( P=0. 003) . The expression of FBXW7 in 20 cases of low grade adenocarcinoma was 5 cases,and the positive rate was 25. 0％( 5/20) . In 15 cases of normal ovarian tissue,9 cases were positive,and the positive rate was 60. 0％( 9/15) . The difference was statistically significant ( P=0. 04) . The expression of ENO1 protein was 27 in 40 cases of high grade adenocarcinoma,and the positive rate of expression was 67. 5％( 27/40) . 5 cases were positive in 15 normal fallopian tubes, and the positive rate was 33. 3％( 5/15 ) . The difference was statistically significant ( P = 0. 024 ) . The expression of ENO1 protein was 15 in 20 cases of low grade adenocarcinoma,and the positive rate of expression was 75. 0％( 15/20) . In 15 cases of normal ovarian tissue,4 cases were positive, and the positive rate was 26. 7％( 4/15 ) . The difference was statistically significant ( P=0. 006) . There was no correlation between the low expression of FBXW7 and the high expression of ENO1 in high grade ovarian adenocarcinoma ( P= 0. 199 ) , but there was a significant correlation between the low expression of FBXW7 and the high expression of ENO1 in low grade ovarian adenocarcinoma ( P<0. 05) . In low grade serous adenocarcinoma,the 5-year survival rates were 44. 4％ and 32. 1％ respectively,with no significant difference ( P = 0. 052 ) . In ovarian high-grade serous adenocarcinoma, the 5-year survival rates of high-expression group and low-expression group were 20. 0％ and 7. 7％, respectively, with no significant difference ( P=0. 097) . In low grade ovarian serous adenocarcinoma,the 5-year survival rate was 7. 4％ in high expression group and 50. 0％ in low expression group ( P=0. 023) . The 5-year survival rates of ENO1 in high-grade serous adenocarcinoma were 0％ and 40. 0％ in high-expression group and low-expression group respectively ( P=0. 001) . Conclusion The low expression of FBXW7 in ovarian adenocarcinoma suggests that FBXW7 may be a tumor suppressor gene in ovarian serous adenocarcinoma, and ENO1 may be an oncogene in ovarian adenocarcinoma. The high expression of FBXW7 in serous adenocarcinoma indicates that ENO1 may be an oncogene,and the survival rate of FBXW7 in serous adenocarcinoma is higher than that in low expression group. The survival rate of the high-expression group was lower than that of the low-expression group. Therefore, they may become a new diagnostic index and therapeutic target for ovarian serous adenocarcinoma.
