ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

The application of mechanics in clinical wound healing has a long history;however,the systematic underlying mechanisms remain unclear.With recent advancements in biomechanics and mechanobiology,the principles regarding how mechanical factors influence the formation,progression,and healing of wounds have gradually been elucidated.Herein,based on progress in theories,technologies,and clinical practices concerning the interplay between mechanics and wound healing,this study introduces the concept of wound-repairing mechanomedicine.Relevant research is systematically reviewed from the perspectives of biomechanics,mechanobiology,and mechanotherapy.Additionally,potential future development directions are prospectively analyzed to provide novel insights into wound care and strategies for preventing scar formation.

Objective:To compare the effectiveness of video laryngoscopy and traditional direct laryngoscopy in neonatal endotracheal intubation teaching.Methods:A total of 52 undergraduate clinical interns in the Department of Neonatology at the First Clinical School of Medicine of Zhengzhou University in June 2024 were selected.The participants were randomly divided into a video laryngoscopy group and a traditional direct laryngoscopy group.After the training，skill assessments were conducted.And a questionnaire was used to evaluate whether there were differences in terms of teaching arrangement, teaching methods, classroom interaction, and teachers' attitudes.Results:The skill assessment score of the video laryngoscope group was (72.85 ± 3.36) points, significantly higher than that of the direct laryngoscope group[(65.81 ± 2.80) points], with a statistically significant difference ( P<0.05). The glottis recognition rate in the video laryngoscope group (88.46%) was higher than that in the direct laryngoscope group (61.54%) ( P<0.05).The intubation success rate in the video laryngoscope group (69.23%) was also higher than that in the direct laryngoscope group (38.7%) ( P<0.05). The results of the teaching satisfaction survey questionnaire showed that the satisfaction ratio for teaching methods in the video laryngoscope group was higher than that in the direct laryngoscope group ( P<0.05), while there were no statistically significant differences between the two groups in terms of teaching arrangements, classroom interaction, assessment and evaluation methods, and teacher attitudes ( P>0.05). Conclusion:Using video laryngoscopy for teaching helps interns better master neonatal tracheal intubation skills and is worth promoting.

Objective:To explore the clinical efficacy of laparoscopic left hemi-fundoplica-tion for gastroesophageal reflux disease (GERD).Method:The retrospective and descriptive study was conducted. The clinical data of 45 patients with GERD who were admitted to Hebei Provincial Hospital of Traditional Chinese Medicine from July 2019 to July 2022 were collected. There were 26 males and 19 females, aged (46±12) years. All patients underwent laparoscopic left hemi-fundoplication. Observation indicators: (1) intraoperative and postoperative conditions; (2) follow-up. Measurement data with normal distribution were expressed as Mean± SD. Count data were expressed as absolute numbers. The paired samples t-test was used for comparison of indicators before and after surgery. Result:(1) Intraoperative and postoperative conditions. All 45 patients successfully underwent the operation, with no conversion to open surgery or intraoperative complications. The operation time was (86±8)minutes, volume of intraoperative blood loss was (12±3)mL, and time to postoperative first flatus was (2.2±0.8)days. Among the 45 patients after surgery, 4 cases had fever, 3 cases had retrosternal dull pain and discomfort, 4 cases had dysphagia, 3 cases had abdominal distension, and 5 cases had constipation. All these symptoms were cured or relieved spontaneously after sympto-matic treatment. The duration of postoperative hospital stay was (3.5±0.5)days. There was no patient with infection, delayed bleeding or perforation.(2) Follow-up. All 45 patients were followed up for 1 year after surgery, with no recurrence of GERD. Gastroscopy showed no esophageal mucosal damage such as erosion or ulcer, and no hiatal hernia occurred. Before surgery, the reflux symptom index score, GERD questionnaire score, reflux disease questionnaire score, lower esophageal sphincter resting pressure, and DeMeester score of 24-hour esophageal pH monitoring were 24.3±1.9, 12.5±2.1,20.1±4.5, (7.1±1.1)mmHg (1 mmHg=0.133 kPa), and 31.4±6.4, respectively. At 1 year after surgery, the above indicators were 2.2±0.7, 6.5±0.5, 4.0±2.6, (23.2±2.9)mmHg, and 6.0±1.4, respectively. There were significant differences before and after surgery ( t=80.75, 18.70,20.09, -33.45, 26.15, P<0.05). Conclusion:Laparoscopic left hemi-fundoplication is safe and feasible for GERD, which can improve the clinical symptoms of patients.

Objective To compare the effects of dexmedetomidine and midazolam on intraoperative blood pressure and postoperative 90-day outcome of endovascular treatment(EVT)in patients with acute anterior circulation large vessel occlusive stroke.Methods Retrospective consecutive patients with acute anterior circulation large vessel occlusion stroke who received EVT within 24 hours of onset,admitted to the Department of Neurology at the Second People's Hospital of Hefei from January 2024 to February 2025 were included.Patients were divided into the dexmedetomidine group and the midazolam group based on the choice of sedative in EVT.Baseline and clinical data were collected from patients,including sex,age,medical history(hypertension,diabetes,atrial fibrillation,stroke history),smoking history,blood pressure at admission(systolic,diastolic,mean arterial pressure),National Institutes of Health stroke scale(NIHSS)score at admission,trial of Org 10172 in acute stroke treatment(TOAST)classification,and site of vascular occlusion(internal carotid artery,M1 segment of the middle cerebral artery).Procedure related parameters,including intravenous thrombolysis before EVT,intraoperative use of tirofiban,modified thrombolysis in cerebral infarction(mTICI)grade,thrombectomy techniques(stent-retriever thrombectomy,aspiration thrombectomy,combined stent-retriever and aspiration thrombectomy,and other salvage measures),number of thrombectomy,time from onset to revascularization,time from puncture to revascularization,blood pressure during EVT(minimum systolic,minimum diastolic,and minimum mean arterial pressure),and blood pressure at the end of EVT(systolic,diastolic,and mean arterial pressure).The primary outcome was good prognosis at 90 days after EVT(modified Rankin scale score of 0-2 at 90 days),while secondary outcome was＞20％decrease in mean arterial pressure during EVT,early neurological improvement(ENI;a decrease on NIHSS score no less than 8 or a reduction of NIHSS score to 0-1 at 24 hours after EVT),and early neurological deterioration(END;an increase of more than 2 points on the NIHSS at 24 hours after procedure).Safety outcomes included any intracranial hemorrhage within 48 hours after EVT,symptomatic intracranial hemorrhage within 48 hours after EVT(sICH;intracranial hemorrhage confirmed by head CT leading to neurological deterioration,with an increase in NIHSS score of at least 4 points,or the presence of potentially fatal intracranial hemorrhage on head CT),pneumonia within 2 weeks after EVT,and the 90-day mortality after EVT.The baseline and clinical data,EVT conditions,primary outcome,secondary outcome,and safety indicators were compared between the two groups.Univariate Logistic regression analysis was used to screen the variables associated with a decrease in mean arterial pressure＞20％during EVT in patients with acute anterior circulation large vessel occlusive stroke.Variables with P＜0.15 and those considered potentially influential based on clinical experience were included in multivariate Logistic regression analysis to identify predictors of a＞20％decrease in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke.Results A total of 93 patients with acute anterior circulation large vessel occlusive stroke who underwent EVT were included,comprising 51 males and 42 females,aged 34 to 99 years,with an average of(71±13)years old.Among them,63 patients were in the dexmedetomidine group,and 30 patients were in the midazolam group.33 patients showed＞20％decreases in mean arterial pressure during EVT,while 60 patients had ≤20％decreases.(1)Compare with the midazolam group,the proportion of female patients in the dexmedetomidine group was lower(36.5％[23/63]vs.63.3％[19/30],P=0.015),and the age was younger([69±13]years vs.[77±13]years,P=0.005).There were no statistically significant differences in other baseline and clinical data(all P＞0.05).(2)In comparison with the midazolam group,the dexmedetomidine group had a higher proportion of patients with more thrombectomy procedures(1.00[1.00,2.00]times vs.1.00[1.00,1.25]times,P=0.011),END(27.0％[17/63]vs.6.7％[2/30],P=0.023),sICH within 48 hours(19.0％[12/63]vs.3.3％[1/30],P=0.041),and a decrease in mean arterial pressure＞20％during EVT(42.9％[27/63]vs.20.0％[6/30],P=0.031).There were no statistically significant differences in the remaining EVT conditions,primary outcome,secondary outcome,and safety indicators(all P＞0.05).(3)The results of univariate Logistic regression analysis showed that diastolic blood pressure at admission(P=0.002),mean arterial pressure at admission(P=0.009),and dexmedetomidine sedation(P=0.036)were the influencing factors of a decrease＞20％in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusion stroke.(4)The results of multivariate Logistic regression analysis showed that dexmedetomidine sedation(OR,3.271,95％CI 1.057-10.126,P=0.040)and higher diastolic blood pressure on admission(OR,1.105,95％CI 1.006-1.213,P=0.037)were independent predictors of a decrease over 20％in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke.Conclusions Dexmedetomidine is an independent predictor of an over 20％decrease in mean arterial pressure during EVT in patients with acute anterior circulation large vessel occlusive stroke,but there is no statistically significant differences in the rate of good neurological function at 90 days and 90-day mortality postoperatively between the two groups.Further prospective randomized controlled studies are needed.

Aim To explore the effects of nuciferine on cognitive behavior and the underlying mechanisms,white matter injury(WMI),neuroinflammation,and ferroptosis in mice with chronic ischemic WMI.Meth-ods Sixty C57BL/6 mice were divided into a control group,a bilateral common carotid artery stenosis(BCAS)model group,and low/high-dose nuciferine groups(20/40 mg·kg-1).A chronic ischemic WMI model was established using BCAS surgery.Following eight weeks of treatment,cognitive behavior(Y-maze,novel object recognition,Morris water maze),white matter integrity(LFB/MBP staining),microglial acti-vation(Iba-1 immunofluorescence),inflammatory cy-tokines(ELISA for TNF-α,IL-1β,IL-6),ferroptosis markers(Fe2+,ROS,MDA,GSH),mitochondrial ultrastructure(electron microscopy),and protein ex-pression of the PI3K/Akt and NRF2/xCT/GPX4 signa-ling pathways(Western blot)were evaluated.Results Compared with the control group,the BCAS group showed significant cognitive decline(P＜0.05),re-duced myelin density,elevated inflammatory cytokines and ferroptosis markers(Fe2+,ROS,MDA),shrunk-en mitochondria,and downregulated PI3K/Akt and NRF2/xCT/GPX4 pathway proteins(P＜0.05).Nu-ciferine intervention significantly ameliorated these in-juries in BCAS mice,with the high-dose group exhibi-ting superior effects(P＜0.05).Conclusions Nu-ciferine exerts protective effects against chronic ische-mic WMI and cognitive impairment by activating the PI3K/Akt and NRF2/xCT/GPX4 signaling pathways,thereby suppressing neuroinflammation and ferroptosis.

Objective To investigate the application effect of cold snare endoscopic mucosal resection(CS-EMR)in the treatment of 6 to 9 mm colorectal small polyps.Methods A total of 82 patients with small colonic polyps in our hospital from March 2022 to August 2023 were collected and divided into the observation group(45 cases received CS-EMR)and the control group[37 cases received hot snare endoscopic mucosal resection(HS-EMR)]according to different surgical methods.The clinical efficacy,polyp resection status,complete polyp resection rate,perioperative indicators and occurrence of complications were compared between the two groups.Results Follow-up for 1 month after operation,the effective rate of treatment in the observation group was higher than that in the control group(P<0.05).There was no statistically significant difference in the polyp resection status or perioperative indicators between the two groups(P>0.05).There was no statistically significant difference in the complete polyp resection rates of patients with different pathological types or total complete resection rate between the two groups(P>0.05).The incidence of delayed bleeding and endoscopic hemostasis rate in the observation group were lower than those in the control group(P<0.05).Conclusion The complete resection rate of 6～9 mm colorectal polyps through CS-EMR was comparable to that of HS-EMR,and CS-EMR has a better efficacy and lower risk of perioperative bleeding,along with higher safety.

Aim To explore the possible regulatory effect of leptin on acyl-CoA synthetase long chain fami-ly member ACSL5 and their effect on migration and in-vasion of breast cancer cell,and to explore the underly-ing mechanism.Methods The expression of leptin receptor was detected by immunofluorescence assay.The migration and invasion ability of MCF-7 cells were detected by wound healing assay and Transwell assay respectively.The downstream target gene of leptin was analyzed by PCR microarray data.The expression of ACSL5 in breast cancer and its correlation with the staging and prognosis of breast cancer patients were as-sessed uing bioinformatics methods.The expression of ACSL5 in MCF-7 cells treated with different concentra-tions of leptin was detected using real time fluorescence quantitative polymerase chain reaction(RT-qPCR).Overexpressing ACSL5 was constructed by lentiviral transfection;the expressions of EMT related proteins,AMPK-α and p-AMPK-α were detected by Western blot.Results Leptin promoted breast cancer cell mi-gration and invasion and EMT.ACSL5 was significant-ly low expressed in breast cancer and related to progno-sis.Leptin downregulated the expression of ACSL5 through OBR.Leptin activated AMPK pathway to downregulate ACSL5 and promote migration,invasion and EMT of breast cancer cells.Conclusions Leptin may promote the migration,invasion and EMT of breast cancer by downregulating ACSL5 through activating AMPK pathway.
