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.

Objective:To explore the efficacy of linaclotide combined with compound polyethylene glycol (PEG) on bowel preparation, and compare it with traditional PEG 3 L and oral sulfate solution (OSS) 3 L methods.Methods:Patients aged 18-70 years who underwent colonoscopy at the Digestive Diseases Hospital, Heilongjiang Provincial Hospital from January to June 2023 were continuously enrolled in the randomized controlled trial and randomly divided into 3 groups using the random number table. Intestinal preparation was conducted according to the protocols of each group, Group A: 3 L PEG; Group B: 3 L OSS; Group C: 290 μg of linaclotide + 2 L PEG. The effects of bowel preparation, adverse reactions, satisfaction, and willingness for repeated bowel preparation were compared.Results:A total of 360 patients were included in the analysis, with 120 patients in each group. There were no statistically significant differences in the median Boston bowel preparation score for each intestinal segment or the total score among the 3 groups (left colon: 3 VS 2 VS 3, H=0.371, P=0.831; transverse colon: 3 VS 3 VS 3, H=0.487, P=0.784; right colon: 2 VS 2 VS 2, H=1.088, P=0.580; total score: 8 VS 8 VS 8, H=0.017, P=0.991). Among the adverse reactions, the incidence of nausea and vomiting in Group B [3.33% (4/120)] was lower than that in Group A [12.50% (15/120), χ2=8.042, P=0.018], and there were no statistically significant differences in other adverse reactions among the 3 groups ( P>0.05). There was no significant difference in the satisfaction level among the 3 groups ( χ2=11.840, P=0.158). The willingness to undergo bowel preparation again in Group C [95.83% (115/120)] and Group B [96.67% (116/120)] was higher than that in Group A [85.00% (102/120)] (Group C VS Group A: χ2=8.127, P=0.004; Group B VS Group A: χ2=9.808, P=0.002), and there was no significant difference between Group C and B ( χ2=0.000, P=1.000). Conclusion:Linaclotide combined with 2 L PEG offers comparable bowel preparation efficacy and safety to 3 L PEG or 3 L OSS, with improved patient compliance due to reduced water intake, suggesting its potential as an enhanced bowel preparation regimen.

Objective To investigate the clinical value of 18F-FDG PET/CT image in assisting CT-guided puncture of pancreatic tumor.Methods One hundred and thirteen patients with pancreatic tumors were selected and then divided into 18 F-FDG PET/CT image-assisted CT-guided group(abbreviation 18F-FDG PET/CT-assisted group)(n=54)and CT-guided group(n=59)according to the different guided puncture methods.The diagnostic efficacy and safety of the two guided puncture biopsy methods were analyzed and compared.Results All patients successfully completed the biopsy.The accuracy(the agreement rate between pathological diagnosis and final clinical diagnosis),sensitivity,and complication rate of the 18F-FDG PET/CT-assisted group were 96.30％(52/54),96.15％(50/52),and 3.70％(2/54);and those of the CT-guided group were 84.75％(50/59),83.64％(46/55),and 15.25％(9/59).Ultimately,it was found that the 18F-FDG PET/CT-assisted group performed better in terms of accuracy and complications than CT-guided group,and the differences were statistically significant(x2=4.280 9,P=0.038 5;x2=5.211 4,P=0.022 4).No serious complications such as hemorrhage,abdominal infection,pancreatic fistula,intestinal fistula and so on occurred in all patients.Conclusion 18F-FDG PET/CT image in assisting CT-guided pancreatic tumor puncture possesses more efficient,precise,and safe characteristics,which is the innovation and expansion of traditional CT image-guided puncture biopsy.However,there is still improvement room in terms of economy and feasibility.

Operation management is an important tool to promote the high-quality development of public hospitals in China.Since the founding of New China,based on China's economic and social development and medical and health system reform,the evolution of operation management of public hospitals in China can be divided into four stages,the system building stage(1949-1978),the liberalization and revitalization stage(1979-1996),the operation mechanism reform stage(1997-2020),and the new stage of high-quality development(2021 present).The development trend of public hospital operation management in future should deepen the public welfare-oriented public hospital operation management,explore the value-oriented medical operation management model based on high-quality development and the refined operation and management model of public hospitals,so as to promote the high-quality development of public hospitals in China.

Total-body PET/CT, with its long axial field of view and high sensitivity detector, has shown potential for reducing the dose of radiopharmaceuticals. However, pediatric patients are significantly more sensitive to radiation and have a higher long-term cancer risk than adults, posing fundamental challenges for dose management in PET/CT examinations for these patients. In this article, the technical characteristics of total-body PET/CT and its radiation exposure status in children were systematically analyzed. The radiation exposure could be controlled by the following optimization strategies: adjusting the CT exposure parameters, optimizing the scanning mode, adding reconstruction algorithm, and reducing the injected dose of radioactive tracer. By addressing both external and internal radiation during the PET/CT scanning process, the overall radiation dose received by pediatric patients can be reduced within a certain range. In addition, this article also discusses the technical differences between “total-body” and “whole-body” concepts, and emphasizes that the future optimization of radiation dose in pediatric PET/CT should be realized by integration of personalized scanning protocols. Through reasonable management of scanning protocols and processes, low-dose and high-quality PET/CT imaging can be achieved in clinical environments, thus maximizing protection of pediatric patient health while minimizing the risks associated with ionizing radiation exposure.

Objective: To explore the correlation between traditional Chinese medicine (TCM) constitution and depressive symptom among school aged children and adolescents, so as to provide evidences for informing constitution based regulation and prevention of depressive symptom. Methods: From June to December 2024, a total of 4 729 students aged 6-14 were recruited by cluster random sampling from 10 primary schools in Baoding (Hebei Province), Heze and Liaocheng (Shandong Province). General information, TCM constitution and depressive symptom were collected. Restricted cubic spline (RCS) models were used to analyze related factors and threshold effects of depressive symptom. Binary Logistic regression was applied to examine the association between depressive symptom and TCM constitution, with subgroup analyses conducted. Results: The detection rate of depressive symptom among the included children and adolescents was 25.82%. RCS analyses indicated non linear associations between depressive symptom and age (inflection point at 10 years old), bedtime (inflection point at 22:00), and wake up time (inflection point at 6:30 ) (all P non linearity <0.01). Linear associations were observed with body mass index (BMI) and sleep duration (all P non linearity > 0.05 ). After adjusting for covariates such as age, BMI and sleep status, binary Logistic regression analyses showed that Yin deficient constitution ( OR =1.26, 95% CI =1.09-1.45) and Phlegm-dampness constitution ( OR =1.42, 95% CI =1.11-1.82) were significantly associated with depressive symptom among children and adolescents (all P <0.05). Conclusions Depressive symptom among school aged children and adolescents is primarily associated with Yin deficiency and Phlegm dampness constitutions in TCM constitution. Active attention should be paid to susceptible TCM constitution among children and adolescents. Targeted health guidance and interventions should be implemented to improve TCM constitution health status for preventing the occurrence of depressive symptom.

Objective:To investigate the predictive value of anti-Müllerian hormone (AMH) on the outcome of microscopic testicular sperm extraction (micro-TESE) in patients with non-mosaic Klinefelter syndrome (KS) of the clinical data and to identify effective predictors for successful micro-TESE.Methods:A retrospective case-control study was conducted on the clinical data of 118 non-mosaic KS patients treated at the Center for Reproductive Medicine of the First Affiliated Hospital of Zhengzhou University between May 2018 and September 2023. Patients were divided into two groups based on whether sperm were successfully retrieved via micro-TESE: the sperm retrieved group ( n=45) and the no sperm retrieved group ( n=73). Differences between the two groups were compared, and multivariate logistic regression analysis was used to identify factors influencing sperm retrieval. Changes in testicular volume and sex hormone levels before and after surgery were also assessed. Results:The sperm retrieval rate was 38.1% (45/118). Patients in the sperm retrieved group were significantly younger [(26.93±3.80) years] than those in the no sperm retrieved group [(28.27±3.92) years, P=0.029], and the AMH level was significantly higher [0.44 (0.18, 1.13) μg/L] than that in the no sperm retrieved group [0.10 (0.03, 0.22) μg/L, P<0.001]. AMH was identified as an independent predictor of micro-TESE outcome in non-mosaic KS patients ( OR=7.867, 95% CI: 2.727-27.242, P=0.001). The area under the receiver operating characteristic curve was 0.802 (95% CI: 0.722-0.883), and the optimal reference threshold for AMH was ≥0.265 μg/L. Postoperatively, testosterone levels decreased significantly by a median of 0.27 μg/L ( P=0.019), while luteinizing hormone levels increased by a median of 2.08 U/L ( P=0.049), with a more significant decline in testosterone levels observed in the no sperm retrieved group by a median of 0.29 μg/L ( P=0.022). Conclusion:AMH can predict successful micro-TESE in non-mosaic KS patients, with higher AMH levels indicating a higher likelihood of success.
