Objective:To evaluate the advantages and short-term clinical effects of totally robotic Nissen 360° fundoplication compared with laparoscopic surgery.Methods:A retrospective analysis was conducted on data of 110 patients undergoing Nissen 360° fundoplication at the Second Department of General Surgery, Yan'an Hospital Affiliated to Kunming Medical University from Aug 2023 to Aug 2024. Among them, 50 cases underwent totally robotic fundoplication, and 60 cases underwent laparoscopic fundoplication. By comparing and analyzing the fatigue level of the primary surgeon during the operations, postoperative incisional pain in patients, swallowing function recovery and the time to resume a normal solid-food diet within 3 months post-surgery, the advantages of totally robotic surgery were evaluated. Additionally, by examining the postoperative recovery of reflux symptoms, postoperative patient comfort, and satisfaction levels in both groups, the short-term clinical outcomes of totally robotic surgery were assessed.Results:Both groups of patients successfully completed the surgeries without any intraoperative or postoperative complications occurring. The fatigue score of the primary surgeon in the totally robotic group was significantly better than that in the laparoscopic group[ (2.34±1.38) vs. (2.89±1.51), t=1.385, P<0.01]. The time taken to resume a normal solid-food diet postoperatively in the totally robotic group was significantly shorter than that in the laparoscopic group[ (27.90±6.77) d vs. (40.78±13.60) d, t =5.765, P<0.01]. Moreover, the postoperative pain comfort level was better in the robotic group than in the laparoscopic group [(1.65±0.72) points vs. (2.23±0.59) points, t=3.742, P<0.01]. Within 12 months postoperatively, the GERD-Q scores in the totally robotic group decreased significantly, and reflux symptoms disappeared, comparable to that in the laparoscopic group. Conclusions:The totally robotic Nissen 360° fundoplication leads to lower fatigue levels for the surgeon. Patients experience significant advantages in terms of postoperative pain perception and dietary recovery. Additionally, it demonstrates excellent postoperative anti-reflux efficacy, high patient comfort, and the surgery is safe and reliable.

As a mechanosensitive ion channel, Piezo1 is expressed in various immune cells and plays an important role in mediating immune response by calcium influx in response to mech-anical signals. Pancreatic parenchymal cells are highly sensitive to mechanical stress. Piezo1 can respond to mechanical stimuli during the initiation and development of pancreatitis. The authors summarize the latest research advancements on the role and molecular mechanisms of Piezo1 in various immune cells and pancreatitis in recent years and discuss the potential role of immune cell Piezo1 in acute and chronic pancreatitis, with an attempt to provide new insights for early inter-vention of pancreatitis.

Objective:To evaluate the safety and effectiveness for the treatment of totally robotic fundoplication.Methods:A retrospective analysis was conducted on the clinical data of 21 patients with gastroesophageal reflux disease (GERD) who underwent unassisted totally robotic fundoplication at the Second Department of General Surgery, Yan'an Hospital Affiliated to Kunming Medical University from Aug 2023 to Jan 2024. The postoperative outcomes were evaluated using SF-36, GERD-Q, and NRS scoring indicators.Results:All 21 patients successfully underwent the surgery. The robotic surgery time was (99±41) minutes, with precise intraoperative anatomy and insignificant blood loss of (1.7±1.4) ml. There were no intraoperative or postoperative complications, and no conversions to open surgery . Postoperative recovery of bowel function was rapid (11.71±3.33) hours, with minimal postoperative pain (NRS score of 1.67±0.48).The postoperative hospital stay was short (3.86±2.90) days, and patient satisfaction was high, SF-36 score of (80.90±1.14);The symptoms of reflux after surgery was significantly reduced.Postoperative GERD-Q score of (4.38±1.69) significantly lower than the preoperative score of (13.90±2.07).Conclusion:Totally robotic fundoplication provides clear view of intraoperative anatomical structures, rapid postoperative recovery, minimal pain, and effective anti-reflux outcomes.

Clinical data of 4 cases of infants with hemophilia complicated with hematorrhachis diagnosed in Guangzhou Women and Children′s Medical Center from January 2017 to December 2018 was retrospectively analyzed.The clinical manifestations of 4 children was atypical, only showing irritability and crying, poor spirit and weak head in the early stage, and torticollis and limb weakness in the late stage may easily contribute to a misdiagnosis.The spinal magnetic resonance imaging is an important diagnosis of hematorrhachis.The most common site of disease was cervicothoracic and thoracolumbar spinal epidural hemorrhage.Of the 4 patients in this article, 1 patient was treated with surgery combined with infusion factor Ⅷ replacement therapy.Three patients were treated with infusion factor Ⅷ replacement therapy alone to obtain clinical rehabilitation.The prognosis of early diagnosis was good, the time from onset to diagnosis in 3 cases was within 1 week, after treatment all had rehabilitation; 1 case within 2 weeks of diagnosis, partial rehabilitation.It is suggested that hemophilia complicated with hematorrhachis in infants is hidden, and it can only be irritable and crying in the early stage, and neurological symptoms appear in the late stage.Improving diagnostic awareness, early diagnosis and early infusion factor replacement therapy are critical for prognosis.

Objective To measure the expression of CD80 and CD86 in renal tissue of lupus nephritis (LN) and explore its mechanism in the development of LN.Methods Forty-nine patients with active LN and 9 patients with minor glomerular abnormalities tissues as controls were studied.The expression of CD80, and CD86 in renal tissues was detected by immunohistochemical methods.Results CD86 was expressed extensively in glomerulus, periglomerular area, tubular epithelial cells and peritubular interstitium, while CD80 was expressed only in tubular epithelial cells and peritubular interstitium.Moreover, the percentage of CD+80 and CD+86 cells in tubular epithelial cells and peritubular interstitium showed a tendency to increase with tubulointerstitial damage.The expression of CD80 and CD86 in renal tissue correlated with the systemic lupus erythematosus (SLE) disease activity index score, the degree of proteinuria, creatinine clearance and anti- dsDNA antibody.Conclusions This study shows that increased CD80 and CD86 expression with the progression of tubulointerstitial lesion might play an important role in the development of lupus nephropathy, and the tubulointerstitial expression of CD80 and CD86 could potentially serve as a surrogate marker of SLE disease activity.The co-stimulatory molecules CDg, and CD86 might play an important role in the pathogenesis of LN.
