Objective:To observe the effects of transcutaneous electrical point stimulation(TEPS)on awakening,cognition,and immune function in patients undergoing laparoscopic cholecystectomy(LC)under general anesthesia.Methods:Ninety patients undergoing LC under general anesthesia were selected as the study subjects and were divided into a control group and an observation group according to the random number table method,with 45 cases in each group.The control group was operated with conventional general anesthesia.The observation group was treated with the same anesthesia as the control group,and TEPS was performed at Hegu(LI4),Zusanli(ST36),and Neiguan(PC6)before the induction of anesthesia until the completion of the operation.The quality of postoperative awakening,hemodynamic indicators,cognitive function,and immune function of patients in the two groups were compared,and the occurrence of adverse reactions was recorded.Results:The time of recovery of spontaneous breathing and extubation time of the observation group were shorter than those of the control group(P<0.05);there was no statistically significant difference in the heart rate(HR)and mean arterial pressure(MAP)between the two groups at the moment before the induction of anesthesia(T1)(P>0.05);at the moment of extubation(T2)and 5 min after extubation(T3),the HR and MAP of patients in both groups were higher than those at T1(P<0.05),and those of the observation group were lower than those of the control group(P<0.05).Preoperatively,there was no statistically significant difference in the Montreal cognitive assessment scale(MoCA)score between the two groups(P>0.05);3 d postoperatively,the MoCA score of the two groups decreased and was higher in the observation group than in the control group(P<0.05).Preoperatively,there was no statistical difference in the comparison of CD4+,CD8+,and CD4+/CD8+between the two groups(P>0.05);3 d postoperatively,the above indicators decreased in both groups(P<0.05)and were higher in the observation group than in the control group(P<0.05).There was no statistical difference in the total incidence of adverse reactions between the two groups(P>0.05).Conclusion:The application of TEPS at Hegu(LI4),Zusanli(ST36),and Neiguan(PC6)with general anesthesia can improve the quality of postoperative awakening,promote hemodynamic stabilization,and improve cognitive function and immune function in LC patients,with good safety.

Objective To observe the value of ultrasound combined with hematologic tests for diagnosing acute complicated appendicitis.Methods Data of 225 patients with acute appendicitis confirmed by surgery and postoperative pathology were retrospectively analyzed.The patients were divided into acute complicated appendicitis group(complicated group,n=33)and acute uncomplicated appendicitis group(uncomplicated group,n=192)based on operational and post operation pathological findings.Clinical data,hematologic test results and ultrasound findings before operation were compared between groups.Multivariate logistic regression was used to construct a combination model for diagnosing acute complicated appendicitis.Receiver operating characteristic(ROC)curve and area under the curve(AUC)were used to evaluate the diagnostic value of predictive factor alone and their combination for diagnosing acute complicated appendicitis,which were then compared with DeLong test.Results Compared with uncomplicated group,patients in complicated group were older,with higher proportion of fever and vomiting,higher level of C reactive protein(CRP)and of neutrophil-to-lymphocyte ratio(NLR),larger external diameters of appendix,also higher proportion of appendiceal intracavitary fecalith and periappendiceal abscess(all P＜0.05).Multivariate logistic regression analysis showed that elevated serum CRP and NLR,increased external diameter of appendix and periappendiceal abscess were all predictive factors of acute complicated appendicitis(all P＜0.05).The diagnostic efficiency of logistic regression model constructed based on the above factors(AUC=0.854)was higher than that of each single predictive factor alone(Z=2.548-4.527,all P＜0.05).Conclusion Ultrasound combined with hematologic tests had high value for diagnosing acute complicated appendicitis.

Objective:To explore the feasibility, safety, and effectiveness of a novel suture instrument for closure of full thickness defects of the gastric wall under gastroscopy.Methods:Ten pigs were used as experimental animals. Perforation model (30 mm in long diameter) was created in the stomach of each pig. The perforations were then closed by the novel suture instrument under gastroscopy. The completion time and efficacy of each perforation repair were recorded. The pigs were euthanized 14 days after the procedure. The healing condition was observed under gastroscopy. A postmortem examination was performed to observe the abdominal infection and healing condition of perforation. Ascites sample was taken for bacterial culture.The stomach biopsy were taken for histopathologic examination.Results:All gastric perforation models in the 10 pigs were established successfully. Endoscopic closure for the stomach perforation was technically successful in all 10 pigs. The procedure time was 34.10±10.32 minutes. All animals survived. Gastroscopy and necropsy showed that the perforation healed well with local adhesion. One pig developed abdominal infection. Ascites culture were negative in 9 cases, 1 bacterial infection was caused by Arcanobacterium pyogenes and Escherichiacoli. The pathology results showed that the muscular layer of the gastric wall defect in the entire group was well repaired. Conclusion:The novel suture instrument is safe and effective in repairing full-thickness gastric wall defects under ordinary single clamp gastroscopy, providing an experimental basis for further clinical research.

Objective:To investigate the current status of medication literacy in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) and its influencing factors.Methods:A cross-sectional study was conducted. According to a stratified random sampling strategy, 105 patients undergoing allo-HSCT were recruited from Fujian Medical University Union Hospital between January and August 2024. General information questionnaire and medication literacy scale were used to collect the demographic characteristics and clinical information of patients. The influencing factors of medication literacy score were analyzed. Univariate analysis was performed by using the Mann-Whitney U test and the Kruskal-Wallis rank sum test; medication literacy scores were compared among subgroups and multivariate analysis was performed by using multiple linear regression model. Results:A total of 105 questionnaires were distributed and returned, yielding 100 valid questionnaires (95.2% valid response rate). Among 100 patients, 54 were male and 46 were female. The medication literacy median score [ M ( Q1, Q3)] was 5 (3, 7) points, indicating a moderate level. Univariate analysis revealed that the medication literacy total score of patients aged <55 years was higher than that of those aged ≥ 55 years ( P = 0.05). The medication literacy score of patients with college education and above was higher than that of those with secondary school or high school, junior high school and below education. Patients with a monthly per capita household income of 4 001-6 000 yuan and >6000 yuan had a higher medication literacy total score compared with those with income of ≤ 2 000 yuan and 2 001-4 000 yuan, and the differences were statistically significant (all P < 0.05). Multivariate analysis showed that aged (< 55 years vs. ≥ 55 years, B = 1.160, 95% CI: 0.488-1.832, P = 0.001), education level (secondary school or high school vs. junior high school and below education, B = 1.888, 95% CI: 1.284-2.492, P < 0.001; college education and above vs. junior high school and below education, B = 3.020, 95% CI: 2.482-3.558, P < 0.001), a monthly per capita household income (4 001-6 000 yuan vs. ≤ 2 000 yuan, B = 0.672, 95% CI: 0.058-1.287, P = 0.032; >6000 yuan vs. ≤2 000 yuan, B = 0.692, 95% CI: 0.020-1.363, P = 0.044) were independent influencing factors of medication literacy total score of patients undergoing allo-HSCT. Conclusions:The medication literacy of patients undergoing allo-HSCT is at middle level and it needs improvement. It is necessary to formulate stratified intervention strategies targeting older patients, those with lower education level and lower income, to optimize to medication information delivery and to strengthen the connection of post-discharge care.
