Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.

Microfibrino-associated protein (MFAP) 2 is an extracellular matrix glycoprotein and a member of the MFAP family. It participates in the assembly of extracellular elastic microfibers.Upregulation of MFAP2 can promote the occurrence and development of various tumors and regulate multiple cancer-related signaling pathways and is related to their prognosis, making it a potential target for tumor treatment. This article summarizes the research progress on the pathogenesis, targeted therapy and prognosis of MFAP2 in malignant tumors.

Objective To evaluate the efficacy,safety and patient compliance of a quadruple therapy containing minocycline compared with the traditional quadruple therapy in the treatment of Helicobacter(H.)pylori.Methods This study included 200 H.pylori positive patients,with 100 assigned to the minocycline-containing bismuth quadruple therapy group(LBMC group)and the other 100 to the amoxicillin-containing bismuth quadruple therapy group(LBAC group).After matching the two groups of patients using the propensity score matching(PSM)method,there were 86 cases in each group.Telephone follow-up was conducted on the 14th day after the start of treatment to record patient medication compliance and adverse drug reactions.A 13C urea breath test was performed for re-examination at least one month after completing the treatment plan and discontinuing medication.The intention-to-treat(ITT)and per-protocol(PP)analyses were used to compare the H.pylori eradication rates between the two groups,and Chi-square test and t-test were used for intergroup comparison.Results In the ITT analysis,the eradication rates of the LBMC group and the LBAC group were 89.5%(77/86,95%CI:82.9%～96.1%)and 82.6%(71/86,95%CI:74.4%～90.7%),respectively.In the PP analysis,the eradication rates were 92.6%(75/81,95%CI:86.8%～98.4%)and 88.8%(71/80,95%CI:81.7%～95.8%),respectively.The adverse reaction rate of the LBMC group was 27.9%(24/86),and that of the LBAC group 31.4%(27/86),showing no statistically significant difference(P>0.05).In terms of compliance,the LBMC group was 94.2%(81/86),and the LBAC group 93.0%(80/86),revealing no statistically significant difference(P>0.05).Conclusion As a first-line treatment for eradicating H.pylori,regimens containing minocycline demonstrate equivalent eradication rates to those containing amoxicillin,with similar safety and compliance.They can be used as an alternative treatment for patients allergic to penicillin.

Objective:To evaluate the safety and effectiveness of rubber band-assisted endoscopic submucosal excavation (RB-ESE) for gastric submucosal tumors (SMT).Methods:A retrospective study was conducted on data of gastric SMT patients who underwent ESE in Affiliated Hospital of Yangzhou University from January 2017 to August 2022. A total of 48 patients were selected and divided into two groups: RB-ESE group ( n=20) and the conventional ESE (C-ESE) group ( n=28). The operation time, bleeding rate and perforation rate during operation, the retention rate of the mucosal cap, the number of clips, postoperative complications, and the hospitalization time were analyzed. Additionally, correlations between complications and tumor size/location and between bleeding and perforation were evaluated. Results:No significant difference was found in the general conditions between the two groups ( P>0.05). The operation time of RB-ESE group (14.82±2.31 min) was significantly shorter than that of C-ESE group (23.70±3.67 min) ( t=-9.539, P<0.001). The intraoperative bleeding rates were 20.0% (4/20) and 42.9% (12/28) in the RB-ESE group and C-ESE group respectively ( χ2=2.743, P=0.098), while the intraoperative perforation rates were 25.0% (5/20) and 46.4% (13/28) respectively ( χ2=2.286, P=0.131). Furthermore, the mucosal cap preservation rate was notably higher in the RB-ESE group at 60.0% (12/20) compared with 7.1% (2/28) in the C-ESE group ( χ2=15.777, P<0.001). The number of clips applied to close the wound was 8.05±1.40 and 10.43±1.96 in the RB-ESE group and C-ESE group respectively ( t=4.925, P<0.001). The postoperative hospital stays were 4.35±0.75 days and 5.00±0.86 days respectively in two groups ( t=2.724, P=0.009). No postoperative bleeding or perforation occurred in either group. The results showed that the occurrence of perforation and bleeding were associated with tumor diameter. Patients with tumor size ≥2 cm showed increased proportions of intraoperative bleeding [68.4% (13/19), P<0.001] and perforation [78.9% (15/19), P<0.001]. There was a correlation between intraoperative bleeding and perforation ( P<0.001). Conclusion:RB-ESE proves to be an effective and safe approach for managing gastric SMT, offering advantages such as reduced operation time and hospital stays, improved retention of the mucosal cap post-operation, and less clips use. The results suggest that RB-ESE could be widely adopted for treating SMT.

Objective To explore the efficacy and safety of endoscopic retrograde appendicitis therapy (ERAT) for pediatric acute appendicitis. Methods Thirty-five pediatric patients with acute simple appendicitis admitted between June 2021 and November 2023 were selected as study subjects. Relevant perioperative data including clinical manifestations, diagnostic and therapeutic processes, as well as treatment and follow-up outcomes were collected. Results All 35 patients successfully underwent ERAT with an operation time ranging from 24 to 75 min. Intubation of the appendiceal lumen was successful in all patients, with pus flushed out or stones removed. After contrast administration and flushing, 16 patients were found to have pus only in the appendiceal lumen with no appendicoliths, while 19 patients had both pus and visible appendicoliths with diameters ranging from 2 to 5 mm. Of 19 patients, 17 appendicoliths were loose and 2 were well-formed. Abdominal pain symptoms were alleviated within a short period, with the average VAS score decreasing from 6.6 preoperatively to 1.7 at 3 hours postoperatively and to 0.2 at 24 hours postoperatively. There was a statistically significant difference in Visual Analogue Scale(VAS) scores before and after surgery (P < 0.05). During follow-up ranging from 3 to 11 months postoperatively, appendicitis recurred in one patient one week after ERAT, while no surgery-related complications occurred in the other patients during follow-up. Conclusion ERAT is a safe and effective endoscopic treatment for pediatric acute appendicitis, with advantages including reduced trauma and shorter recovery time. It is particularly suitable for pediatric patients with acute simple appendicitis complicated by appendicoliths, appendiceal lumen stenosis, or intra-appendiceal abscesses.
