Objective To analyze the disease burden of chronic kidney diseases (CKD) attributed to high body mass index (BMI) in China from 1992 to 2021 and predict the disease burden for the next decade, and to provide evidence for the prevention and treatment of CKD. Methods Using the Global Burden of Disease (GBD) database and the Joinpoint model, the average annual percentage rate change (AAPC) of the mortality rate and disability-adjusted life year (DALY) rate was calculated to describe and analyze the CKD disease burden attributed to high BMI in China from 1992 to 2021. The ARIMA model was employed to predict and analyze the change trend of the CKD disease burden. Results From 1992 to 2021, the mortality rate and DALY rate attributed to high BMI-induced chronic kidney disease showed an upward trend. Compared to 1992, the attributed number of deaths increased by 324.38%, and DALYs increased by 268.56%; the mortality rate increased by 64.00%, and the DALY rate grew by 51.62%. From 1992 to 2021, the mortality rate and DALY rate for males were lower than those for females, but the growth rate for males exceeded that of females. From 1992 to 2021, the mortality rate and DALY rate of chronic kidney disease attributed to high BMI in China increased with age. The average annual change rate of chronic kidney disease attributed to high BMI in China from 1992 to 2021 (mortality rate: 1.40 per 100,000 (95% CI: 1.04–1.76), DALY rate: 1.43 per 100 000 (95% CI: 1.17–1.70)) was higher than thHuaiyin Normal University, Huai'anher social demographic index (SDI) regions. The ARIMA model predicted that the age-standardized mortality rate increased from 2.91 per 100 000 in 2022 to 3.05 per 100 000 in 2026, and the age-standardized DALY rate increased from 69.65 per 100 000 in 2022 to 73.58 per 100 000 in 2026. Conclusion Chronic kidney disease attributed to high BMI in China is on the rise, and it will continue to grow in the future. The focus of CKD prevention and control should be on males and the elderly, while active measures should be taken to reduce the occurrence and progression of chronic kidney disease.

Objective To explore the research hotspots and development trends in the field of cancer treatment in the past decade. Methods The CNKI and Web of Science Core Collection databases were searched for Chinese and English articles related to cancer treatment published over the last 10 years. Bibliometric research methods were employed, including keyword cluster analysis of published literature. Results A total of 45 455 Chinese articles and 866 958 English articles were retrieved. Combining the visualization analysis results and the current research dilemma of tumor treatment revealed that the current research hotspots of tumor treatment domestically and internationally can primarily focus on four key areas. In the realm of targeted therapy, efforts are directed towards the discovery of new drug targets, overcoming resistance to targeted therapy, and the development of monoclonal antibodies and antibody–drug conjugates. In the field of immunotherapy, the emphasis lies in enhancing the response rate to immune checkpoint inhibitors, determining the mechanisms behind resistance to immunotherapy, and improving the safety of treatment. The research in traditional Chinese medicine (TCM) covers evidence-based evaluation studies on TCM treatment, the identification of populations that can gain the most benefit from TCM, and strategies for improving the quality of life. In the area of novel drug development, cutting-edge technologies, such as organoid-based screening for anticancer drugs, synthetic biology, and artificial intelligence, are under investigation. Conclusion New targeted drugs, immune efficacy improvement, multidisciplinary integration, nano-delivery, and TCM innovation are the key research directions in the field of tumor therapy in the future.

Objective: To evaluate the safety and efficacy of preoperative autologous blood donation (PABD) under anesthesia monitoring in elective surgical procedures, and to provide scientific data for promoting its clinical application. Methods: 1) A total of 1 164 patients scheduled for elective surgery and met the criteria for stored autologous blood transfusion in our hospital from March 2022 to September 2023 were enrolled. Prior to surgery, stored autotransfusion was performed under anesthesia monitoring. During the operation, blood pressure (BP), heart rate (HR), blood oxygen saturation (SpO ) and other basic life indicators before and after blood collection were recorded and analyzed. Adverse reactions during blood collection were documented, and potential influencing factors were analyzed. 2) The autologous transfusion group (experimental group, patients receiving intraoperative autologous blood reinfusion) was compared with the allogeneic transfusion group (control group, patients without PABD during the same period) using propensity score matching. The length of hospital stay, transfusion-related costs, perioperative hemoglobin (Hb), hematocrit (Hct), platelet count (Plt) and coagulation function were compared between the two groups after matching. Results: 1) Three patients (0.26%) had adverse reactions during blood collection. Autologous blood transfusion was performed in 443 patients (38.1%) during or after operation, with no adverse reaction during blood transfusion. 2) The systolic blood pressure (SBP) and diastolic blood pressure (DBP) of patients after blood collection were lower than before blood collection, and the SpO was higher than before blood collection, with statistically significant differences (P<0.05); There was no significant difference in heart rate before and after blood collection (P>0.05); Our analysis found that age, gender, blood collection volume, department, or mild-to-moderate circulatory system complications didn’t significantly affect BP, HR and SpO fluctuations (P>0.05). 3) The experimental group had shorter hospital stays and lower transfusion costs than the control group (P<0.05). 4) No significant differences were observed in Hb, Hct, Plt levels or coagulation function (PT, APTT) between the two groups after operation (P>0.05). The hospitalization duration and transfusion related expenses in the experimental group were lower than those in the control group (P<0.05). Conclusion: PABD under anesthesia monitoring is safe and feasible in elective surgeries across diverse patient groups and surgical fields. It reduces the costs and conserves blood resources, which is worthy of further promotion.

ObjectiveThe study aims to investigate the intervention effect of modified Xiangsha Liujunzitang （M-XSLJZ） on intestinal-derived lipopolysaccharide （LPS）-activated Kupffer cell inflammation in rats with hyperlipidemia spleen deficiency syndrome. MethodsSeventy male SD rats were randomly divided into seven groups （n=10）： blank control （CON）， high-fat diet without spleen deficiency （HFD）， high-fat diet with spleen deficiency （SD-HFD）， M-XSLJZ low-， medium-， and high-dose groups （XS-L， XS-M， XS-H）， and western medicine control （R）. Spleen deficiency was induced in SD-HFD， XS-L， XS-M， XS-H， and R groups via irregular diet combined with exhaustive swimming for 15 days. The CON group received a standard diet， while other groups were fed a high-fat diet for 10 weeks to establish the hyperlipidemia model. After successful modeling， rats were treated for 8 weeks： M-XSLJZ was administered at 3.51， 7.02， 14.04 g·kg^-1 in XS-L， XS-M， and XS-H groups， respectively. The R group received 9×10^-4 g·kg^-1 of a reference drug. D-xylose excretion rate was measured by the phloroglucinol method. Blood lipids were assessed using an automated biochemical analyzer. Hematoxylin-eosin （HE） staining was used to evaluate the pathological conditions of the liver， and oil red O staining was used to observe the lipid deposition in the liver. The levels of LPS， portal vein serum LPS， LPS-binding protein （LBP）， serum interleukin-6 （IL-6）， IL-1β， and tumor necrosis factor-α （TNF-α） were detected by enzyme-linked immunosorbent assay （ELISA）. Immunofluorescence was used to evaluate CD86 expression and CD68/TLR4 co-localization in the liver. Protein levels of TLR4， MyD88， NF-κB p65， and p-NF-κB p65 in Kupffer cells were analyzed via Western blot automated protein analysis. Hepatic IL-6， TNF-α， and IL-1β mRNA and protein levels were measured using Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot. ResultsCompared with the CON group， the SD-HFD group showed a decrease in D-xylose excretion （P<0.01）. TC， TG， HDL-C， and LDL-C increased （P<0.05， P<0.01）. A large number of hepatic lipid vacuoles and orange-red lipid droplet deposition appeared in the liver. Ileal LPS， portal LPS， and LBP increased （P<0.05， P<0.01）. The levels of serum IL-6， TNF-α， and IL-1β increased （P<0.01）. The expression of CD86 was upregulated （P<0.01）， and the co-expression of CD68 and TLR4 was enhanced. The protein levels of TLR4， MyD88， and p-p65 in Kupffer cells increased （P<0.01）. The mRNA and protein levels of IL-6， TNF-α， and IL-1β increased （P<0.05， P<0.01）. Compared with the HFD group， the SD-HFD group exhibited decreased D-xylose excretion （P<0.01）， higher HDL-C， LDL-C （P<0.05）， increased portal LBP and LPS （P<0.05）， increased serum IL-6 and TNF-α （P<0.01）， upregulated CD86 （P<0.01）， enhanced CD68/TLR4 co-expression， and higher TNF-α mRNA/protein （P<0.05）. Compared with the SD-HFD group， all M-XSLJZ treatment groups showed reduced TC， TG， and LDL-C （P<0.05， P<0.01）. XS-H and R groups displayed improved hepatic lipid deposition. XS-H and R groups had lower ileal LPS， portal LPS， and LBP levels （P<0.05， P<0.01）. All M-XSLJZ treatment groups exhibited reduced serum IL-6， IL-1β， and TNF-α （P<0.01）. The XS-H group showed downregulated CD86 （P<0.01） and weakened CD68/TLR4 co-expression. The XS-H group had reduced TLR4， MyD88， and p-NF-κB p65 in Kupffer cells （P<0.01）. XS-H and R groups showed lower IL-6， TNF-α， and IL-1β mRNA/protein （P<0.05， P<0.01）. ConclusionM-XSLJZ may exert its lipid-lowering effects by inhibiting intestinal-derived LPS and alleviating Kupffer cell inflammation in the liver.

The application of artificial intelligence （AI） in the medical field has significantly improved medical efficiency， yet it has also posed numerous ethical challenges. From the perspective of traditional Confucianism， this paper explored ethical challenges faced in the application of medical AI and the responses of Confucianism， elaborating on the importance of Confucianism in achieving value alignment. This paper analyzed the ethical dilemmas faced by medical AI in practical applications from four aspects， including the doctor-patient trust crisis， patient safety issues， fairness and conflict of interest， and challenges of responsibility attribution. It also explored the application of Confucianism in the ethical governance of medical AI， focusing on the analysis of how “benevolence，”“righteousness，” and role ethics deal with issues such as doctor-patient trust， patient safety， fairness， market profit-seeking， and responsibility allocation. By emphasizing the guiding role of ethical principles in technological development through the principle of “governing technology with ethics，” the achievement of the value alignment goal in medical AI can be promoted. Confucianism provides an important ethical foundation for the value alignment of medical AI. Its core concepts run through the deep integration of technology and ethics， offering unique cultural wisdom and practical solutions for AI governance on a global scale.

OBJECTIVE To construct an evaluation index system for the core competencies of ethics committee members of drug clinical trial institution， providing a basis for optimizing the training system for committee members， improving the quality of ethical review， and fully safeguarding the safety and rights of subjects. METHODS Using methods such as literature research and expert consultation， a preliminary core competency evaluation index system was constructed. The Delphi method was employed to revise and validate it， ultimately forming an evaluation index system for the core competencies of ethics committee members. Based on this system， a questionnaire survey was conducted among 90 ethics committee members from 29 drug clinical trial institutions nationwide， comparing their importance rating and self-assessment scores of the core competency indexes. RESULTS The evaluation system constructed included 4 primary indicators （ethics and professional knowledge， ethics review ability， communication and expression ability， moral integrity and work style） and 39 secondary indicators （familiarity with the content of clinical trial-related laws and regulations， ability to complete project ethics review and identify ethical defects in research protocols within a short period of time， ability to judge the scientific value of clinical research， etc.）. The results of questionnaire survey showed that the interviewed ethics committee members had significant capability gaps in dimensions such as regulatory knowledge， ethical norms， review efficiency， risk judgment， and problem analysis. The differences between the importance rating scores of corresponding secondary indicators and the self-assessment scores were all no less than 0.38. CONCLUSIONS This study has developed a quantifiable and stratified core competency assessment tool for ethics committee members. It can provide a scientific framework for committee member training， qualification certification， and standardized management of ethics committees.

Aim To investigate the regulatory effect of morphine postconditioning in the LSG on remodeling after myocardial infarction. Methods SD rats were randomly divided into four groups: sham operation group (Sham), myocardial infarction group (MI), myocardial infarction + saline group (Control) and myocardial infarction + morphine postconditioning group (MI + Morphine) . The rat MI model was constructed by ligating the left anterior descending coronary artery, and then morphine was given to the LSG by percutaneous posterior approach. After four weeks, the changes of cardiac function in rats were detected by ultrasound. Masson staining was used to detect fibrosis changes; the expression of Collagen I and Collagen III protein was detected by Western blot. The mRNA expression of ANP and BNP was detected by RT-qPCR. The expression of JJLOR in LSG was detected by immunofluorescence. The concentration of catecholamine in plasma and myocardial tissue was detected by ELISA. Results Compared with the sham group, the cardiac function of the MI group was significantly impaired, the myocardial tissue showed significant fibrosis changes, and the concentration of catecholamine in plasma and myocardial tissue significantly increased. Compared with the control group, the MI + Morphine group reduced myocardial fibrosis collagen deposition in rats after MI, inhibited the expression of ANP and BNP in myocardial tissue, reduced the concentration of catecholamine, and improved the cardiac function of MI rats. Immunofluorescence results showed that JJLOR was expressed in LSG after MI and increased after morphine postconditioning. Conclusions This study shows that morphine postconditioning in the LSG has a protective effect on myocardial remodeling after myocardial infarction. The mechanism may be related to the activation of JJLOR in the LSG by morphine and the reduction of catecholamine release from sympathetic nerve endings.

Objective:To compare the trueness of incisal guidance of implant-supported single crowns designed by patient-specific motion(PSM)with that designed by average-value virtual articulator(AVA).Methods:The study had recruited 12 participants with complete dentition and stable incisal guidance.An intraoral scanner was used to scan digital casts and record two types of patient-specific mo-tion(data only including protrusive movement,and data including protrusive movement and lateral pro-trusive movement).The lingual surfaces of the maxillary incisors which guided the protrusive movement was selected and elevated to create a reference cast.A maxillary central incisor of original casts was vir-tually extracted and implanted to generate a working cast.The Dental system software program was used to design implant-supported single crowns with the anatomical coping design method.The incisal guidance was designed by different methods.The incisal guidance in control group was designed by the average-value virtual articulator.The incisal guidance in experiment groups was designed by the patient-specific motion only including protrusive movement(PSM1)and with the patient-specific motion including protru-sive movement and lateral protrusive movement(PSM2).The incisal guidance of prosthesis designed by these 3 methods were compared with the original incisal guidance in Geomagic Control 2015(3DSystem,America).The measurements included:Average of positive values,ratio of positive area and maximum value reflecting supra-occlusion;average of negative values,ratio of negative area and minimum value re-flecting over-correction;and root mean square reflecting overall deviation.Results:Statistical data were collected using the median(interquartile range)method.The average of positive values,ratio of positive area and average of negative values of the PSM2 group were smaller than those of the control group[8.0(18.8)μm vs.37.5(47.5)μm;0vs.7.2％(38.1％);-109.0(63.8)μm vs.-66.5(64.5)μm],and the ratio of negative area of PSM2 group was larger than those of the control group[52.9％(47.8％)vs.17.3％(45.3％)],with significant differences(P all＜0.05).The ratio of positive area[0.1％(7.0％)]and average of negative values[-97.0(61.5)μm]of PSM1 group,were smaller than those of the control group,and the ratio of negative area[40.7％(39.2％)]of the PSM1 group was larger than that of the control group,with significant differences(P＜0.05).The average of positive values[20.0(42.0)μm]and ratio of positive area of PSM1 group was larger than that of the PSM2 group with significant differences(P＜0.05).Conclusion:To establish the incisor guidance of implant-supported single crowns,compared with the average-value virtual articulator and the patient-specific motion only including protrusive movement,the patient-specific motion including protrusive movement and lateral protrusive movement is more conducive to reducing the protrusive interference of prosthesis and improving the occlusal fit.

Objective:To investigate the efficacy and prognosis of different surgical approaches in sporadic medullary thyroid carcinoma.Methods:A retrospective analysis was conducted on 101 patients with sporadic medullary thyroid carcinoma (MTC) who underwent surgical treatment at the Department of Thyroid Surgery, China-Japan Union Hospital of Jilin University, from Feb. 2009 to Nov. 2023. The patients included 36 males and 75 females, with a male-to-female ratio of 1:2.1. The median age of the patients was 47 years old, with an age range of 21 to 72 years old. The study divided participants into two groups based on their surgical methods: an observation group (78 cases) and a control group (23 cases). The observation group received surgical methods in accordance with expert consensus, while the control group did not. The study compared the efficacy and prognosis of the two groups.Results:Statistical differences were found between the two groups in terms of stage II and III in TNM staging, intraoperative frozen pathological findings, number of lymph node resections in the central group, number of lymph node metastases in the central group, number of lymph node resections in the lateral cervical region, postoperative follow-up time, and five-year postoperative serum procalcitonin (Ctn) levels ( P<0.05) .Both groups of patients obtained a significant decrease in Ctn after surgical treatment. In the observation group, Ctn was at the remission level in 57 cases (73.1%), at the stable level in 13 cases (16.7%), and at the progression level in 8 cases (10.2%), while in the control group, Ctn was at the remission level in 20 cases (86.9%), at the progression level in 3 cases (13.1%), and there were no patients at the stable level after the operation.One patient (1.3 per cent) in the observation group had a recurrence after surgery; Two patients (8.7 per cent) in the control group had a recurrence. Conclusions:Standardised and thorough surgery can maximise the clearance of metastatic lymph nodes, effectively reduce the recurrence rate, achieve better efficacy, and improve the long-term prognosis of patients without increasing the risk of surgery and postoperative complications.

Objective To explore the possible mechanism of Xiebaisan in protecting against allergic asthma in rats from the perspective of host intestinal flora metabolism.Methods SPF SD rats were divided into normal group(NC group),model group(M group),and Xiebaisan group.The allergic asthma rat model was established by ovalbumin.Changes in lung histopathology were observed by HE staining.Colon contents were harvested for 16S rDNA high-throughput sequencing to assess changes in the intestinal flora structure and function.Serum and lung tissue samples were collected for non-targeted metabolomics by Ultra-high performance liquid-time-of-flight mass spectrometer.Results HE staining showed some improvement of lung histomorphology in asthmatic rats in the Xiebaisan group compared with that in the M group.16S rDNA high-throughput sequencing showed that the diversity of intestinal flora was decreased in the M group and increased in the Xiebaisan group compared with the M group,the microecosystem of intestinal was improved.Non-targeted metabolomics of serum showed regulation of amino acid metabolism and the mTOR pathway in the Xiebaisan group,and partially reversed differential metabolite expression in the M group.Non-targeted metabonomics of lung tissue samples showed regulation of carbon metabolism,vascular smooth muscle and cAMP signaling pathways in the Xiebaisan group,and partially reversed differential metabolite expression in the M group.Conclusions The protective effects of Xiebaisan on allergic asthma in rats may be related to improvement of the morphological structure of lung tissue,the diversity of intestinal flora,and regulation of mTOR,vascular smooth muscle contraction,and cAMP pathways,which affect amino acid and carbon metabolism.
