Objective:To evaluate the efficiency of the four domestic language models,ERNIE Bot,ChatGLM2,Spark Desk and Qwen-14B-Chat,all with a massive user base and significant social attention,in response to consultations about PCa-related perio-perative nursing and health education.Methods:We designed a questionnaire that includes 15 questions commonly concerned by patients undergoing radical prostatectomy and 2 common nursing cases,and inputted the questions into each of the four language models for simulation consultation.Three nursing experts assessed the model responses based on a pre-designed Likert 5-point scale in terms of accuracy,comprehensiveness,understandability,humanistic care,and case analysis.We evaluated and compared the performance of the four models using visualization tools and statistical analyses.Results:All the models generated high-quality texts with no mis-leading information and exhibited satisfactory performance.Qwen-14B-Chat scored the highest in all aspects and showed relatively sta-ble outputs in multiple tests compared with ChatGLM2.Spark Desk performed well in terms of understandability but lacked comprehen-siveness and humanistic care.Both Qwen-14B-Chat and ChatGLM2 demonstrated excellent performance in case analysis.The overall performance of ERNIE Bot was slightly inferior.All things considered,Qwen-14B-Chat was superior to the other three models in con-sultations about PCa-related perioperative nursing and health education.Conclusion:In PCa-related perioperative nursing,large language models represented by Qwen-14B-Chat are expected to become powerful auxiliary tools to provide patients with more medical expertise and information support,so as to improve the patient compliance and the quality of clinical treatment and nursing.

Objective:To explore the effect of the"internet+health education system"in nursing care after stapler circumci-sion.Methods:A total of 260 patients underwent stapler circumcision in the Outpatient Department of our hospital from January 2022 to July 2022,of whom 130 received routine nursing after operation(the control group),and the other 130 internet+medical nursing service based on the internet+health education system(the experimental group).We followed up the patients on the 1st,3rd,7th and 30th day after surgery,recorded their Visual Analogue Scale(VAS)scores within 24 hours postoperatively,their satisfac-tion scores with surgery and nursing,the incidence of complications and falloff of the stapler nails,and compared them between the two groups.Results:The postoperative VAS scores of the patients and the incidences of postoperative edema,bleeding,infection and other complications were significantly lower(P<0.05),the falloff of the stapler nails markedly sooner,and the patients'satisfaction scores with surgery and nursing service remarkably higher(P<0.05)in the experimental than in the control group(P<0.05).Conclusion:The application of the internet+health education system in nursing care after stapler circumcision can impart relevant knowledge to the patients,enhance their self-care ability,effectively reduce postoperative complications,and improve the patients'sat-isfaction with surgery and nursing service.

Objective:To study the clinical manifestations and treatment of neonatal testicular torsion (NTT) and to summarize the experience of diagnosis and treatment.Methods:The clinical data of the patients with NTT admitted to the Department of Pediatric Urology in Guangzhou Women and Children's Medical Center from January 2015 to January 2021 were analyzed retrospectively. The data included demographic information, testicular torsion duration, clinical presentation, ultrasonography findings, surgical procedures, pathological results, follow-ups, and prognosis.Results:A total of 17 cases were enrolled in this study, and the median age was 5.2 d, ranging from 1 d to 17 d; the weight ranging from 2 800 g to 4 000 g. 11 cases of left testicular torsion and 6 cases of right testicular torsion. The median time from onset to medical attention was 3.8 d, ranging from 10 h to 15 d. The first manifestations being reported were scrotal swelling, color change, or painless mass. Emergency ultrasound revealed that the blood flow signal in the testis was significantly reduced or disappeared, and heterogeneous mass echoes were detected in the scrotum. Surgical exploration was performed in all 17 cases and confirmed to be testicular torsion. There were 15 cases of extravaginal torsion and 2 cases of intravaginal torsion. There were 6 cases of clockwise torsion and 11 cases of anticlockwise torsion. The average degree of twisted testis was 450.8°, ranging from 270° to 720°. The rate of orchiectomy was 88.2% (15/17). All patients were followed up for a minimum of 1 year postoperatively. None of the patients experienced postoperative bleeding or infection at the scrotal incision site. There were no instances of recurrent testicular torsion, and the contralateral testicles showed no abnormalities. In 2 cases where the affected testicle was preserved, ultrasound reevaluation at 6 months postoperatively revealed atrophy of the affected testicle.Conclusions:NTT is rare in clinics and lacks specificity, with a high rate of testis loss. When the newborns exhibit scrotal swelling, color change, or other abnormalities, testicular torsion cannot be ruled out, and early surgical exploration is required.

Objective: To estimate the incidence of HIV-1 infection in men who have sex with men (MSM) in key areas of China through HIV-1 limiting antigen avidity enzyme immunoassay (LAg-Avidity EIA), analyze the deviation from the actual results and identify influencing factors, and provided reference for improving the accuracy of estimation results. Methods: Based on the principle of the cohort randomized study design, 20 cities were selected in China based on population size and the number of HIV-positive MSM. The sample size was estimated to be 700 according to the HIV-1 infection rate in MSM. MSM mobile phone app. was used to establish a detection appointment and questionnaire system, and the baseline cross-sectional survey was conducted from April to November 2019. LAg-Avidity EIA was used to identify the recent infected samples. The incidence of HIV-1 infection was calculated and then adjusted based on the estimation formula designed by WHO. The influencing factors were identified by analyzing the sample collection and detection processes. Results: Among the 10 650 blood samples from the participants, 799 were HIV-positive in initial screening, in which 198 samples (24.78%) missed during confirmation test. Only 621 samples were received by the laboratory. After excluding misreported samples, 520 samples were qualified for testing. A total of 155 samples were eventually determined as recent infection through LAg-Avidity EIA; Based on the estimation formula , the incidence of HIV-1 infection in MSM in 20 cities was 4.06% (95%CI:3.27%-4.85%), it increased to 5.53% (95%CI: 4.45%-6.60%)after the adjusting for sample missing rate. When the sample missing rate and misreporting rate were both adjusted, the incidence of HIV-1 infection in the MSM increased to 5.66% (95%CI:4.67%-6.65%). The actual incidence of HIV-1 infection in MSM in the 20 cities might be between 4.06% and 5.66%. Conclusions: Sample missing and misreporting might cause the deviation of the estimation of HIV-1 infection incidence. It is important to ensure the sample source and the quality of sample collection and detection to reduce the deviation in the estimation of HIV-1 infection incidence.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

OBJECTIVE: To explore the feasibility and efficacy of laparoscopic transcystic drainage and common bile duct exploration in the treatment of patients with difficult biliary stones. METHODS: Between April 2020 and December 2021, eighteen patients with difficult biliary stones received laparoscopic transcystic drainage (C-tube technique) and common bile duct exploration. The clinical characteristics and outcomes were retrospectively collected. The safety and effectiveness of laparoscopic transcystic drainage and common bile duct exploration were analyzed. RESULTS: Among the eighteen patients with difficult biliary stones, thirteen patients received traditional laparoscopic transcystic drainage, and the remaining five received modified laparoscopic transcystic drainage. The mean surgical duration were (161±59) min (82-279 min), no bile duct stenosis or residual stone was observed in the patients receiving postoperative cholangiography via C-tube. The maximum volume of C-tube drainage was (500±163) mL/d (180-820 mL/d). Excluding three patients with early dislodgement of C-tube, among the fifteen patients with C-tube maintained, the median time of C-tube removal was 8 d (5-12 d). The duration of hospital stay was (12±3) d (7-21 d) for the 18 patients. Five C-tube related adverse events were observed, all of which occurred in the patients with traditional laparoscopic transcystic drainage, including two abnormal position of the C-tube, and three early dislocation of the C-tube. All the 5 adverse events caused no complications. Only one grade one complication occurred, which was in a patient with modified laparoscopic transcystic drainage. The patient demonstrated transient fever after C-tube removal, but there was no bile in the drainage tube and the subsequent CT examination confirmed no bile leakage. The fever spontaneously relieved with conservative observation, and the patient recovered uneventfully with discharge the next day. All the 18 patients were followed up for 1-20 months (median: 9 months). Normal liver function and no recurrence of stone were detected with ultrasonography or magnetic resonance cholangiopancreatography (MRCP). CONCLUSION Laparoscopic transcystic drainage combined with common bile duct exploration is safe and feasible in the treatment of patients with difficult biliary stones. The short-term effect is good. Modified laparoscopic transcystic drainage approach may reduce the incidence of C-tube dislocation and bile leak.

Objective: To systematically examine the effectiveness and tolerability of psilocybin for treating end-of-life anxiety symptoms. Methods: The Medline, Embase, CENTRAL, and PsycINFO databases were searched up to November 25, 2020. We enrolled clinical trials investigating psilocybin for treating end-of-life anxiety symptoms. Meta-analysis was conducted using random-effects model. Results: Overall, five studies were included, revealing that psilocybin was superior to the placebo in treating state anxiety at 1 day (Hedges’ g, -0.70; 95% confidence interval, -1.01 to -0.39) and 2 weeks (-1.03; -1.47 to -0.60) after treatment. Psilocybin was more effective than placebo in treating trait anxiety at 1 day (-0.71; -1.15 to -0.26), 2 weeks (-1.08; -1.80 to -0.36), and 6 months (-0.84; -1.37 to -0.30) after treatment. Psilocybin was associated with transient elevation in systolic (19.00; 13.58–24.41 mm Hg) and diastolic (8.66; 5.18–12.15 mm Hg) blood pressure compared with placebo. The differences between psilocybin and placebo groups with regard to allcause discontinuation, serious adverse events, and heart rates were nonsignificant. Conclusion Psilocybin-assisted therapy could ameliorate end-of-life anxiety symptoms without serious adverse events. Because of the small sample sizes of the included studies and high heterogeneity on long-term outcomes, future randomized controlled trials with large sample sizes are needed.

Objective:To investigate the effects of electroacupuncture at Baihui (DU20) and Shenting (DU24) on brain function of APP/PS1 mice. Methods:Sixteen 4-month-old APP/PS1 mice in the same litter were randomly divided into model group (n = 8) and electroacupuncture group (n = 8). Eight transgenic negative mice in the same litter were as control group. The electroacupuncture group accepted electroacupuncture at Baihui and Shenting for 16 weeks. They were assessed with Object Recognition Test before and after intervention, and observed under small animal functional magnetic resonance imaging with regional homogeneity (ReHo) analysis. Results:Compared with the control group, the discrimination ratio decreased in the model group after intervention (P < 0.05), while it increased in the electroacupuncture group compared with that in the model group (P < 0.05). Compared with the control group, ReHo of right basal forebrain and left hippocampus decreased in the model group before intervention. Compared with the control group, ReHo decreased in bilateral hippocampus group and increased in retrosplenial cortex in the model group after intervention; while it increased in bilateral hippocampus and motor cortex and decreased in anterior cingulate gyrus in the electroacupuncture group compared with that in the model group. Conclusion:Electroacupuncture at Baihui and Shenting may delay the decline of learning and memory ability in Alzheimer's disease model mice, which may relate to the regulation of functional activities in hippocampus.
