Objective:To investigate the key technical aspects of laparoscopic anti-reflux surgery (LARS) in complex gastroesophageal reflux disease (GERD) with hiatal hernia (HH) and evaluate the feasibility and efficacy of reoperation.Methods:A retrospective analysis was conducted on 28 patients with complex GERD treated at Zhejiang Provincial People's Hospital from Feb 2020 to May 2024. Preoperative examinations were recorded, and surgical videos were reviewed to reconstruct operative time, critical intraoperative steps, complications, and management techniques. Postoperative follow-up via telephone and outpatient visits assessed symptom relief, complications, and medication use.Results:All 28 patients (4 robotic-assisted and 24 conventional laparoscopic surgeries) successfully underwent LARS, with an operative duration of (152.6±10.3) minutes and a postoperative hospital stay of (4.0±1.9) days. Large HH 9 cases, intraoperative bleeding 6 cases, pleural rupture 3 case, and esophageal perforation 1 case, preoperative diagnoses included short esophagus 2 cases and 7 redo surgeries. The overall recurrence rate was 11%. Postoperative complications occurred in 14%. The redo surgeries group achieved 71% symptom resolution. At 1-12 months of follow-up, 82% of patients were asymptomatic, and 82% discontinued proton pump inhibitor therapy.Conclusions:Complex scenarios requiring specialized techniques in LARS increase surgical difficulty and risks. Standardized management of the hernia sac, hiatal repair, neurovascular protection, identification of anatomical landmarks in reoperations, selection of biological mesh, and adhesiolysis may reduce recurrence rates and complication risks.

BACKGROUND:Eupatilin,a flavonoid active component derived from Artemisia sinensis,has been reported to relieve inflammation and improve neurological scores in rats with subarachnoid hemorrhage,but its role and mechanism in learning and memory remain unclear.OBJECTIVE:To investigate the effects of eupatilin on learning and memory abilities and P38 mitogen activated protein kinase(p38 MAPK)/signal transducer and activator of transcription-3(STAT3)pathway proteins in rats with subarachnoid hemorrhage.METHODS:A total of 50 Sprague-Dawley rats were randomly divided into sham surgery group,model group,eupatilin group,hesperetin group,eupatilin+hesperetin group,with 10 rats in each group.Except for the sham surgery group,the rats in the other groups were used to construct a subarachnoid hemorrhage model through intravascular perforation.Two hours after successful modeling,the eupatilin group was injected with 10 mg/kg eupatilin via the tail vein,the hesperetin group was injected with 50 mg/kg hesperetin(p38 MAPK/STAT3 signaling pathway activator)via the tail vein,the eupatilin+hesperetin group was injected with 10 mg/kg eupatilin and 50 mg/kg hesperetin via the tail vein,and the sham surgery group and the model group were injected with 10 mL/kg saline via the tail vein.The drug treatment lasted for 24 hours.The neurologic deficit score and Morris water maze experiment were applied to detect the neurological function and learning and memory abilities of rats.Hematoxylin-eosin staining was performed to detect the histopathological changes of the hippocampus.TUNEL method was used to detect neuronal apoptosis.Immunohistochemical staining was conducted to detect the number of doublecortin-positive cells in hippocampal tissue.Western blot was applied to detect the expression of p38 MAPK/STAT3 protein in hippocampal tissue.RESULTS AND CONCLUSION:Compared with the sham surgery group,rats in the model group had lower neurological deficit scores,learning and memory abilities,and number of doublecortin-positive cells(P<0.05),and higher neuronal apoptosis rate and protein expression of p-p38 MAPK/p38 MAPK and p-STAT3/STAT3(P<0.05).Compared with the model group,rats in the eupatilin group showed higher neurological deficit scores,learning and memory abilities,and number of doublecortin-positive cells(P<0.05),and lower neuronal apoptosis rate and protein expression of p-p38 MAPK/p38 MAPK and p-STAT3/STAT3(P<0.05),while those in the nerolone group showed lower neurological deficit scores,learning and memory abilities,and number of doublecortin-positive cells(P<0.05),and higher neuronal apoptosis rate and protein expression of p-p38 MAPK/p38 MAPK and p-STAT3/STAT3(P<0.05).Compared with the eupatilin group,rats in the eupatilin+hesperetin group had lower neurological deficit scores,learning memory abilities,and number of doublecortin-positive cells(P<0.05),and higher neuronal apoptosis rate and protein expression of p-p38 MAPK/p38 MAPK and p-STAT3/STAT3(P<0.05).Hematoxylin-eosin staining showed that compared with the model group,the nerve cells were more neatly arranged in the eupatilin group,disorganized in the hesperetin group,and arranged in a similar way to the model group in the eupatilin+hesperetin group.To conclude,eupatilin may improve learning and memory abilities of rats with subarachnoid hemorrhage by inhibiting the p38 MAPK/STAT3 signaling pathway.

Objective:To investigate the application value of 3D printed model in hemostasis training for laparoscopic sleeve gastrectomy.Methods:The retrospective and descriptive study was conducted. Data were collected from six surgeons who participated in hemostasis training for laparoscopic sleeve gastrectomy using 3D printed model at Zhejiang Provincial People′s Hospital in July 2023. All participants were male, aged (33.5±9.9)years. A 3D printed model simulating bleeding during laparoscopic sleeve gastrectomy was created using hydrogel. Videos were recorded to document the surgeons′ hemostasis techniques and outcomes during laparoscopic sleeve gastrectomy. Two external expert reviewers blindly assessed the training videos using the objective structured assess-ment of technical skills (OSATS) scoring system to evaluate mesentery mobilization, vessel exposure, vessel clipping and bleeding after vessel clipping. Observation indicators: (1) face validity and content validity of the 3D printed model; (2) validity verification of the 3D printed model. Measurement data with normal distribution were represented as Mean± SD. Comparison between groups was conducted using the t test. Results:(1) Face validity and content validity of the 3D printed model. The surgeons′ scores for overall impression, fidelity, texture, appearance, workspace and tactile similarity of the 3D printed model were 4.5±0.6, 4.0±0.6, 3.7±0.5, 4.2±0.8, 3.8±0.8 and 4.2±0.4, respectively. The surgeons′ scores for similarity to real scenarios, operation convenience, learning curve shortening and operation skills improving, patient risk reduction, trainee′s interest enhancing, confidence increasing and recommendation for promotion were 4.0±0.6, 4.2±0.8, 4.3±0.8, 4.3±0.5, 4.3±0.5, 4.0±0.6 and 4.8±0.4, respectively. (2) Validity verification of the 3D printed model. The OSATS scores and operation time to treat bleeding during laparoscopic sleeve gastrectomy for expert surgeons were 18.7±0.6 and (125±12)seconds, respectively, versus 13.7±1.5 and (212±51)seconds for junior doctors, showing significant differences between the two groups ( t=5.30, -2.89, P<0.05). Conclusion:The 3D printed model effectively simulates bleeding scenarios during laparoscopic sleeve gastrectomy and distinguishes between different technical levels of expertise.

Background: Currently available guidelines contain conflicting recommendations on the management of blood pressure (BP) in patients with diabetes mellitus (DM). Therefore, it is necessary to appraise the guidelines and summarize the agreements and differences among recommendations. Methods: Four databases and the websites of guideline organizations were searched for guidelines regarding BP targets and thresholds for pharmacologic therapy in DM patients, and the included guidelines were appraised with the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument. Results: In 6,498 records identified, 20 guidelines met our inclusion criteria with 64.0% AGREE II scores (interquartile range, 48.5% to 72.0%). The scores of the European and American guidelines were superior to those of the Asian guidelines (both adjusted P<0.001). Most of the guidelines advocated systolic BP targets <130 mm Hg (12 guidelines, 60%) and diastolic BP targets <80 mm Hg (14 guidelines, 70%) in DM patients. Approximately half of the guidelines supported systolic BP thresholds >140 mm Hg (10 guidelines, 50%) and diastolic BP thresholds >90 mm Hg (nine guidelines, 45%). The tiny minority of the guidelines provided the relevant recommendations regarding the lower limit of official BP targets and the ambulatory BP monitoring (ABPM)/home BP monitoring (HBPM) targets and thresholds in DM patients. Conclusion The lower official BP targets (<130/80 mm Hg) in patients with DM are advocated by most of the guidelines, but they contain conflicting recommendations on the official BP thresholds. Moreover, the gaps regarding the lower limit of official BP targets and the ABPM/HBPM targets and thresholds need to be considered by future study.

ObjectiveTo investigate the characteristics of left ventricular structural damage in patients with primary aldosteronism(PA).MethodsA total of 438 inpatients with hypertension from January 2007 to June 2010 were screened for PA,and diagnosis was made in 213 PA patients and 225 patients with essential hypertension (EH).The left ventricular structure of all subjects was evaluated according to the results of echocardiographic measurements.Results The duration of hypertension and plasma aldosterone level in patients with PA were significantly higher (P＜ 0.01 ),while the serum potassium and plasma renin activity were significantly lower (P＜0.01 ) than those in patients with EH.The interventricular septum thickness,left ventricular end-diastolic dimension,left ventricular mass index (LVMI),left ventricular end-diastolic volume,and stroke volume in patients with PA were significantly higher than those in EH patients( P＜0.01 ) after the duration of hypertension was corrected.In patients with PA,the prevalence of left ventricular hypertrophy (LVH) was higher than that in EH patients ( 53.1％ vs 33.8 ％,x2 =16.57,P ＜ 0.01 ). Normal left ventricular geometry ( NG ),concentric remodeling ( CCR ),concentric hypertrophy( CCH),and eccentric hypertrophy (ECH) were found respectively in 24.9％,22.1％,22.1％,and 30.9％ of patients with PA.Multiple stepwise regression analysis showed that the seated plasma aldosterone level (β=0.43,P ＜ 0.01 ) and systolic blood pressure (β =0.45,P ＜ 0.01 ) were the main factors that influenced LVMI.The course was the main parameter that influenced relative wall thickness(β=0.011,P＜0.05 ).Conclusion The prevalence of LVH is higher in patients with PA than that in EH patients.The eccentric hypertrophy is the most common left ventricular geometrical pattern in patients with PA.

The clinical data of 330 patients with primary aldosteronism (PA) from January 2006 to March 2010 were retrospectively analyzed. The prevalence of 1, 2, and 3 stage hypertension in these subjects was 3.64％,20. 91％, and 75.45 ％, respectively. Of all PA patients, 89.09％ were young adults and 81.82％ were overweight or obese. There was a marked preponderance of male patients in the overweight or obese group ( P＜0. 01 ). The incidence of hypokalemia was 32. 12％. The concentration of serum potassium was not associated with the disease course. Logistic regression showed that the concentration of plasma aldosterone was an independent risk factor of hypokalemia in PA patients( P＜0. 01 ). 79. 09％ PA patients presented the plasma aldosterone level over 12 ng/dl and the renin activity level of less than 1 ng · ml-1 · h-1. The aldosterone-to-rennin activity ratio was ＞20 in 94.24％ of the patients with PA.
