Objective To preliminarily investigate the safety and efficacy of donor pancreas needle biopsy in simultaneous pancreas-kidney transplantation. Methods Clinical data of 7 cases undergoing donor pancreas biopsy were collected retrospectively. All cases underwent donor pancreas biopsy before or during simultaneous pancreas-kidney transplantation. Frozen section or paraffin sectioning techniques were used for tissue preparation, and hematoxylin-eosin and Masson staining were performed to histologically evaluate the donor pancreas. The quality of donor pancreas was comprehensively assessed by combining histological findings with the donor's clinical data. Postoperative follow-up data of 5 simultaneous pancreas-kidney transplant recipients were collected to summarize the safety of donor pancreas biopsy and the prognosis of transplant recipients. Results The 7 pancreas donors were aged 28 to 62 years, with a body mass index ranging from 20.76 to 27.68 kg/m². Liver ultrasound indicated fatty liver in 3 cases, while pancreatic ultrasound did not reveal any significant abnormalities. Among them, biopsy was performed on 2 donors after completion of pancreatic procurement and processing, and the frozen section histology showed moderate acute pancreatitis changes (edema of acinar cells, necrosis and inflammatory cell infiltration). Combined with a serum amylase level elevated more than 3 times the upper limit of normal value, these two donor pancreases were finally discarded. The remaining 5 cases underwent biopsy immediately after pancreatic vascular anastomosis during simultaneous pancreas-kidney transplantation, and histological evaluation was performed on paraffin-embedded sections. No biopsy-related complications (such as bleeding, pancreatic fistula, etc.) occurred after transplantation. One recipient died of severe infection 2 months after transplantation, while the other 4 recipients were followed up for more than 5 years, with well-functioning transplant kidneys and pancreases. Conclusions Donor pancreas biopsy is relatively safe, and the risk of biopsy-related complications after transplantation is controllable. Comprehensive assessment of donor pancreas quality by combining histological evaluation with the donor's clinical indicators is conducive to improving the accuracy of donor pancreas selection and organ utilization.

With the continuous deepening of medical insurance payment reform, the implementation of the ambulatory patient groups(APG) based point system for payment has posed new challenges to the quality management of outpatient electronic medical record writing, as well as the supervision and operation management of outpatient costs in hospitals. A certain hospital began information technology construction in July 2021. By introducing diagnostic grouping functions into the outpatient electronic medical record system, the hospital strengthened the standardization of medical record writing. It also established an intelligent audit system for medical insurance costs to conduct full-process supervision of outpatient medical expenses and developed an intelligent operation analysis system for outpatient APG to provide a basis for hospital operation management decisions and performance distribution. These measures effectively improved the quality of outpatient medical record, reduced outpatient medical costs, and optimized their structure. The application of the intelligent medical insurance audit system also effectively prevented certain non-compliant issues in medical insurance payments, which can provide a reference for other medical institutions.

Objective To explore the identification method,pathogenesis,clinical characteristics and individualized pharmacotherapy of asymptomatic hyperuricemia after renal transplantation.Methods The pharmacist was on duty at the organ transplant outpatient clinic.During this time,they analyzed and sorted out the medications,identified and differentiated a case of asymptomatic hyperuricemia related to spironolactone in a patient who had undergone a renal transplant,and provided comprehensive care throughout the entire process.Results The asymptomatic hyperuricemia in this patient might be associated with spironolactone,and the adverse reactions of the patient were alleviated by pharmacists through optimizing clinical treatment.Up to now,no hyperuricemia occurred.Conclusions Pharmacists are required to collaborate closely with clinicians to establish medication profiles for patients under long-term follow-up and to closely monitor and evaluate drug-related adverse reactions.Additionally,they should assess the renal function and immune status of transplant recipients promptly and formulate individualized treatment plans in order to enhance the long-term survival of both the transplanted kidneys and the recipients.

With the advancement of China's healthcare reform,enhancing the capacity of primary healthcare services has become a pivotal task.Colorectal cancer,one of the most prevalent malignancies in China,highlights the critical importance of early screening and diagnosis to improve patient survival rates.This study,guided by the principles of Party building and Xi Jinping Thought on Socialism with Chinese Characteristics,examines the implementation and outcomes of a rural outreach program focused on colorectal cancer screening and diagnostic technologies.By promoting the dissemination of colorectal cancer screening initiatives,the paper aims to provide empirical evidence to support the deepening of primary-care services,foster high-quality ad-vancement of grassroots health services,and align with the national Healthy China Initiative,thereby more effectively safeguarding population health.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

OBJECTIVE To investigate ameliorative effects and mechanisms of two probiotics(Bacillus subtilis,Lactobacillus acidophilus)combined with Aurantii Fructus Immaturus(AFI)on functional dyspepsia(FD)in rats.METHODS Rats were randomly divided into blank group,model group,positive control group(domperidone group,2.7 mg/kg),AFI group(9 g/kg),L.acidophilus group(5×107 cfu/kg),B.subtilis group(5×107 cfu/kg),L.acidophilus+AFI group(L.acidophilus 5×107 cfu/kg+AFI 9 g/kg),and B.subtilis+AFI group(B.subtilis 5×107 cfu/kg+AFI 9 g/kg),with 8 rats in each group.Except for the blank group,FD model was established by tail-clamping stimulation+hunger and satiety disorder+swimming exhaustion in other groups.After modeling,each group was given the corresponding drug/probiotic suspensions/physiological saline intragastrically,once a day,for 14 consecutive days.After the last medication,gastric emptying rate and the rate of propulsion of the small intestine in rats were measured;the levels of brain-gut peptide-related indicators[gastrin(GAS),substance P(SP),vasoactive intestinal peptide(VIP),somatostatin(SS)and cholecystokinin(CCK)]in the serum of rats were measured.The pathological morphology of the gastric antrum tissue and duodenal tissue was observed.Cecal contents from the rats were collected for gut microbiota sequencing analysis.The protein expression levels of tyrosine kinase receptor c-Kit and stem cell factor(SCF)in the gastric antrum tissue,as well as Toll-like receptor 4(TLR4),myeloid differentiation factor 88(MyD88),and nuclear factor κB(NF-κB)in the duodenal tissue of the rats were detected.RESULTS Compared with the blank group,model group showed significantly lower gastric emptying rate,small intestinal propulsion rate,serum levels of GAS and SP,relative abundance of Firmicutes,Ace,Chao and Sobs indexes of the gut microbiota,and protein levels of SCF and c-Kit in gastric antrum(P＜0.05),while serum levels of VIP,SS and CCK,relative abundance of Bacteroidetes,as well as protein expressions of TLR4,MyD88,and NF-κB,were significantly higher(P＜0.05).The histological structure of the gastric antrum tissue appeared basically normal;however,abnormalities were observed in the duodenal structure,with a significant infiltration of inflammatory cells visible.Compared with the model group,all treatment groups significantly modulated most of the above indexes(P＜0.05).The histological structure of the gastric antrum tissue was normal.Except for the B.subtilis group and the B.subtilis+AFI group,the pathological states of the duodenum in the remaining rats gradually recovered.Compared with each single drug group,most of above indexes in rats from each combination group showed further improvement(P＜0.05).CONCLUSIONS The combination of AFI with two probiotics can improve gastrointestinal motility in FD rats,and the effect is superior to that of using the drugs alone.The specific underlying mechanisms may be related to the activation of the SCF/c-Kit signaling pathway and the inhibition of the TLR4/MyD88/NF-κB signaling pathway.

Objective:To assess the effectiveness of kinetic parameters of 18F-prostate specific membrane antigen (PSMA)-1007 PET/MR in distinguishing tumor recurrence (TR) from radiation necrosis (RN) in glioma patients. Methods:From January 2023 to June 2023, imaging data of 10 patients (6 males, 4 females; media age of 39.5 years) with gliomas who were suspected of recurrence and were referred for 18F-PSMA-1007 PET/MR scans at Sun Yat-Sen University Cancer Center were retrospectively analyzed. Static parameters from 18F-PSMA-1007 PET scans, including SUV max, SUV mean, metabolic tumor volume (MTV), and total lesion′s PSMA (TLP), as well as dynamic parameters including K 1, k 2, k 3, k 4, net influx rate (K i), and volume of distribution ( Vt) were obtained by using compartmental and multigraphical models. Additionally, parameters from dynamic contrast-enhanced MRI (DCE-MRI) were collected. Mann-Whitney U test was used to compare parameter differences between TR and RN groups. Spearman rank correlation analysis was used to explore the correlation between K i and DCE-MRI parameters. Results:Finally, 8 cases were diagnosed as TR and 2 cases were diagnosed as RN. The kinetic compartmental model-based evaluation determined that irreversible 2-tissue model (2T3K) provided the best-fitting results. The differences in SUV mean (median: 2.48 vs 0.89; Z=-2.09, P=0.044), SUV max (median: 4.04 vs 1.40; Z=-2.09, P=0.044), and K i (median: 1.33×10 -2vs 3.87×10 -3;Z=-2.10, P=0.044) between TR and RN groups were statistically significant. Some parameters of DCE-MRI also showed differences between the two groups ( Z=-2.09, P=0.044 for all). The K i yielded moderate correlation with DCE-MRI parameter Ve ( rs=0.650, P=0.042), while correlations between K i and other DCE-MRI parameters were not significant ( rs values: from -0.207 to 0.632, all P>0.05). Conclusion:Dynamic and multi-parametric 18F-PSMA-1007 PET/MR system holds promise for accurately distinguishing TR from RN in treated glioma patients.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the short-term efficacy and safety of robot-assisted laparoscopic partial nephrectomy（RAPN）for non-metastatic pathological stage T 3a renal cell carcinoma. Methods:The clinical and pathological data of 45 patients with pathologically confirmed non-metastatic T 3a renal cell carcinoma who underwent RAPN at Sun Yat-sen University Cancer Center between January 2016 and December 2023 were retrospectively reviewed. There were 30 males and 15 females. The average age of the cohort was（54.3±10.7）years，and the average clinical tumor diameter was（4.9±1.8）cm. Of all the patients，35（77.8%）were asymptomatic，7（15.6%）presented with hematuria，and 3（6.7%）presented with lumbar pain. Preoperative imaging assessed 34 patients（75.6%）as having clinical stage T 3a，all suspected of involving the collecting system or perirenal fat invasion；the remaining 11 patients（24.4%）were assessed as having stage T 1-2 disease. The median R.E.N.A.L. nephrectomy score was 8.0（7.0，10.0）. A history of hypertension，diabetes，or chronic kidney disease was present in 18 patients（40.0%）. The primary endpoint was progression-free survival，and the secondary endpoints included postoperative complications and short-term renal function outcomes. Survival curve was estimated using the Kaplan-Meier method，and renal function comparisons were made using the paired t-test. Results:The RAPN was performed through a transabdominal approach in 32 patients（71.1%），with a median estimated blood loss of 150.0（50.0，300.0）ml. Seven（15.6%）patients required intraoperative blood transfusion. The median length of postoperative hospital stay was 4.0（4.0，6.0）days. Postoperative complications occurred in 6 patients（13.3%），including 5（11.1%）with mild complications and 1（2.2%）with a severe complication. Renal function returned to baseline in 24 of 39 evaluable patients（61.5%），while 3 patients（7.7%）developed surgery-related chronic kidney disease 3 to 12 months postoperatively，but none required dialysis. The median follow-up time was 31.8（22.7，50.9）months，12（26.7%）patients received programmed cell death protein 1 inhibitor adjuvant therapy postoperatively. During follow-up，3 patients experienced tumor recurrence，the 3-year progression-free survival rate of the entire cohort was 95.4%.Conclusions:For some carefully selected patients with T 3a renal cell carcinoma，RAPN performed by experienced surgeons is a feasible and safe option，providing excellent short-term oncological outcomes，complication control，and renal function recovery. The long-term efficacy remains to be seen.
