Diabetic nephropathy（DN） is a common and severe microvascular complication of diabetes. In recent years， the classical herbal formula Shenqi dihuang decoction has demonstrated unique advantages in the clinical treatment of DN. This article conducts a systematic review of the mechanisms of action and clinical applications of Shenqi dihuang decoction in the treatment of DN. It reveals that the mechanism by which this formula improves DN involves multi-target synergistic regulation. For instance, Shenqi dihuang decoction exerts multiple pharmacological effects by regulating signaling pathways including phosphatidy linostiol 3-kinase/protein kinase B， AMP-activated protein kinase/silent information regulator 1/forkhead box O1， and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 pathways.These effects include regulating glucose and lipid metabolism， inhibiting oxidative stress， reducing inflammation， improving insulin resistance， modulating cell death （apoptosis/autophagy/ferroptosis/pyroptosis）， and preventing renal fibrosis. Existing clinical studies indicate that Shenqi dihuang decoction and its modified formulas， alone or in combination with other therapeutic methods， can significantly improve glucose and lipid metabolism， reduce proteinuria， and delay renal function decline in patients with DN. These effects are superior to those of Western medicines such as irbesartan， valsartan， and empagliflozin， and the treatment demonstrates good safety. Future research should leverage systems biology and artificial intelligence technologies to further elucidate the integrated mechanisms in the treatment of DN by Shenqi dihuang decoction， thereby advancing the precision and standardization of its clinical application.

A unified consensus statement on medication-related osteonecrosis of the jaw (MRONJ) has not yet been established among the Asian member countries or regions of the Asian Federation of Osteoporosis Societies (AFOS). This study aimed to develop a consensus on MRONJ in patients with osteoporosis across these countries and regions. In this study, the term “Asia-Pacific” refers specifically to the Asian member countries and regions of AFOS. A structured survey consisting of nine MRONJ-related questions was distributed across 10 countries and regions to assess the level of agreement and summarize regional perspectives. In addition, a manual literature review and voting were conducted to evaluate the current evidence on MRONJ. The key aspects of MRONJ, including definition, staging, diagnosis, pathogenesis, risk factors, management, and prevention, were generally consistent among the AFOS countries and regions. The annual incidence and incidence rate of MRONJ associated with low-dose antiresorptive therapy in patients with osteoporosis ranged from 0.025% to 0.136% and 21 to 283 cases per 100,000 person-years, respectively. However, evidence regarding the benefits of drug discontinuation before dental surgery, such as tooth extraction, remains insufficient. Large-scale, multinational studies across AFOS countries and regions are warranted to determine the incidence of MRONJ better and evaluate the impact of antiresorptive drug discontinuation before dental procedures. These findings may contribute to the devel opment of effective evidence-based strategies for preventing MRONJ in patients with osteoporosis.

Objective To establish a forensic age inference method based on age-related changes in maxillofacial CBCT imaging of Han population in North China.Methods CBCT imaging data of Han people aged 7～50 years were collected from September 2021 to September 2023.Mimics 17.0 software was used to perform 3D reconstruction on 480 cases that met the inclusion criteria(420 cases in the experimental group,60 cases in the blind test group,with a 50%male-to-female ratio)and obtain measured values for 16 indicators.The data were then statistically analyzed using SPSS 27.0 to identify age-related significant indicators and establish regression equations.Results Regression equations based on age-related significant indicators were established for different genders and age intervals.The accuracy of the equations decreased as the age interval increased.The blind test accuracy rates of regression equations for males across different age groups ranged between 62.6%and 80.6%,while for females,they ranged between 55.3%and 76.6%.Conclusion This study enriches maxillofacial skeletal data for Chinese population and establishes multivariate age inference regression equations based on significant indicators of age-related changes in maxillofacial CBCT,providing a new reference basis and inference method for forensic age assessment.

Gastric ulcer(GU)is one of the common,frequently-occurring and intractable diseases of the digestive system.Spleen-stomach deficiency cold type is the most common and hard-to-cure syndrome pattern of GU,and is both a focus and a challenge in medical research.Therefore,constructing a scientific,reasonable,and clinically practical animal model of GU with spleen-stomach deficiency cold type and formulating objective and effective evaluation criteria are of great significance for in-depth research on the pathogenesis and treatment of GU.In this paper,the methods for constructing GU animal models of spleen-stomach deficiency cold type are comprehensively introduced by systematically reviewing the relevant literature.Firstly,the construction methods of pathological models of GU in Western medicine are introduced,including pyloric ligation method,water immersion-restraint stress method,ethanol-induced method,acetic acid-induced method,etc.This paper expounds the establishment methods for spleen-stomach deficiency cold syndrome type model in traditional Chinese medicine(TCM),including diet disorder method,bitter cold diarrhea method,excessive fatigue method,Qi consumption and Qi impairment method,and overeating sour-flavor method.This paper focuses on the construction methods for disease-syndrome combination GU models of spleen-stomach deficiency cold type,including two-factor modeling method and three-factor modeling method.Meanwhile,the evaluation indices of GU animal models of spleen-stomach deficiency cold type were summarized from various aspects,including animal physical signs(appearance symptoms,animal behavior,and metabolic indices),as well as tissue morphology and molecular biology-related indicators(gastric function,oxidative stress,inflammatory factors,other cytokines,four coagulation parameters,intestinal flora detection),for constructing a comprehensive evaluation system.From the perspective of prescription-based verification,this paper further analyzes the drug composition and pharmacological effects to infer the syndrome type of the treated animal model,so as to verify whether the target animal model is successfully constructed.This review aims to provide a valuable reference for establishing a syndrome-specific GU animal model that closely aligns with clinical reality and embodies the principles of Chinese medicine.This will further advance research on TCM-pattern GU syndromes and deepen the exploration of herbal medicine-based treatments for GU,ultimately promoting the clinical integration and advancement of Chinese medicine in GU therapy.

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 evaluate the effectiveness and safety of zoledronic acid in patients with Paget′s disease of bone based on clinical data from a single medical center.Methods:This retrospective study included 24 patients diagnosed with Paget′s disease of bone and treated with zoledronic acid at Peking Union Medical College Hospital between January 2009 and June 2020. Demographic data, clinical symptoms, treatment efficacy, and safety outcomes were collected. The primary efficacy measure was serum alkaline phosphatase(ALP) levels. Treatment was considered effective if ALP levels returned to normal or decreased by more than 75% from baseline in the difference between the ALP level and its normal median value.Results:Among the 24 patients with Paget′s bone disease, the most commonly affected site was the skull(in 17 cases). All patients received a single 5 mg intravenous infusion of zoledronic acid. Serum ALP levels significantly decreased after treatment. Among the 15 patients who completed at least 3 months of follow-up, all achieved treatment success. The median time for serum ALP levels to reach the target was 13.1(9.4, 26.1) weeks. In 12 patients, ALP levels normalized within a medium of 16.9(11.5, 37.3) weeks, and remained stable over a medium follow-up of 4.56(2.42, 5.71) years. The most common side effects were hypocalcemia(21 cases, 87.5%) and flu-like symptoms(17 cases, 70.8%). Seven patients had severe hypocalcemia(serum calcium<1.75 mmol/L), and they had higher baseline levels of ALP, calcium, and phosphorus compared to those with mild hypocalcemia.Conclusions:Zoledronic acid 5 mg intravenous infusion effectively controlled disease activity in patients with Paget′s disease of bone. Generally, Most patients achieved treatment goals within 3-4 months, with sustained remission for a median of 4 years. Hypocalcemia was the most frequent side effect, underscoring the importance of timely calcium and vitamin D supplementation.

The implementation of new medical technology projects is a key way for hospitals to improve their medical technology level and core competitiveness. Standardizing medical technology management has become an important part of the construction of the medical quality system in public hospitals of China. In May 2022, a tertiary comprehensive hospital established a " 243" cross departmental collaborative management system, organically integrating multiple information systems within the hospital, and building a medical new technology whole-process information management platform covering the basic system layer, business platform layer, and system function layer. It was officially launched in November 2022, realizing the full process closed-loop management of medical new technology projects from application, approval, project initiation, tracking to completion, improving management quality and efficiency. As of March 2024, the platform had accepted 203 applications for new technologies, of which 139 had been approved and achieved good results, providing references for other hospitals to standardize the management of medical new technologies and reduce medical risks.

Objective To explore the influencing factors of early postpartum pelvic organ prolapse(POP)after vaginal delivery in advanced maternal age primipara.Methods Clinical data of 153 postpartum women were collected from Beijing Tongren Hospital Mentougou Campus,Capital Medical University,from June 2015 to May 2024.According to whether pelvic organ prolapse occurred during the 6-week postpartum reexamination of the primiparas,the parturients were divided into two groups:non-POP group(91 cases)and POP group(62 cases).Univariate and multivariate Logistic regression analyses were conducted to identify the independent factors influencing early postpartum POP.Subgroup analysis was also performed to assess the relationship between family history of POP and early postpartum POP after adjusting for confounding factors.Results Multivariate Logistic regression analysis revealed that neonatal birth weight,maternal pre-pregnancy body mass index(BMI),use of delivery balls,and family history of POP were independent factors associated with early postpartum POP occurrence(P＜0.05).Among the parturients who did not use of delivery balls,before and after using Logistic regression to adjust for birth weight,pre-pregnancy BMI and perineal laceration,the impact of family history of POP on the occurrence of POP was statistically significant(P＜0.05).However,among the parturients who used the delivery balls,regardless of whether the adjustment was made or not,the impact of family history of POP on the occurrence of POP was not statistically significant(P＞0.05).Conclusion Neonatal birth weight,maternal pre-pregnancy BMI,and family history of POP are risk factors for early postpartum POP,while the use of delivery balls is a protective factor.Women with a family history of POP are advised to use delivery balls to reduce the risk of early postpartum POP.
