ObjectiveTo observe the clinical efficacy and safety of Yishen Jiangtang decoction combined with conventional Western medicine treatment in managing stage G3A3 diabetic kidney disease (DKD) in the patients with the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis, and to explore its mechanism of inhibiting the endoplasmic reticulum stress (ERS)-apoptosis axis and delaying renal fibrosis (RF). MethodsA single-center, randomized, parallel-controlled clinical trial was conducted. A total of 78 patients diagnosed with stage G3A3 DKD and traditional Chinese medicine (TCM) pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis and treated in the Department of Nephrology and the Department of Endocrinology of the People's Hospital Affiliated to Fujian University of Traditional Chinese Medicine from March 2025 to February 2026 were enrolled. They were randomly assigned at a 1∶1 ratio into a control group (conventional Western medicine treatment) and an experimental group (Yishen Jiangtang decoction combined with conventional Western medicine treatment), with 39 patients in each group. The treatment lasted for 12 weeks. Basic demographic data and medical history were collected before and after treatment. The two groups before and after treatment were compared in terms of the following parameters: Blood urea nitrogen (BUN), serum creatinine (SCr), estimated glomerular filtration rate (eGFR), urinary albumin-to-creatinine ratio (UACR), fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C). Enzyme-linked immunosorbent assay (ELISA) kits were used to measure serum glucose-regulated protein 78 (GRP78), serum cysteinyl aspartate-specific protease-3 (Caspase-3), and serum and urinary transforming growth factor-β1 (TGF-β1) levels before and after treatment. TCM symptom scores, TCM syndrome efficacy, and overall clinical efficacy were evaluated before and after treatment. Spearman correlation analysis was performed to explore the correlations of serum levels of GRP78 and Caspase-3, as well as serum and urinary levels of TGF-β1, with renal function, proteinuria, and glucose and lipid metabolism indicators in patients with DKD. In addition, safety indicators were also monitored. ResultsA total of 75 patients completed the study (38 in the control group and 37 in the experimental group). ① Baseline data: The two groups were comparable in terms of sex and age, with no statistically significant difference. ② Efficacy outcomes: Compared with baseline levels, both groups showed reductions in BUN, SCr, UACR, FBG, TG, TC, LDL-C, and TCM symptom scores (P<0.01) and increases in eGFR level (P<0.01). Moreover, the experimental group outperformed the control group in altering the indicators above (P<0.05). Regarding TCM syndrome efficacy, the total response rate in the experimental group was 83.78%, which was higher than that (57.89%) in the control group (P<0.05). Regarding overall clinical efficacy, the total response rate in the experimental group was 78.38%, which was higher than that (50.00%) in the control group (P<0.05). ③ Mechanism outcomes: Compared with baseline levels, both groups showed declined serum levels of GRP78, Caspase-3, and TGF-β1 and urinary level of TGF-β1 after treatment (P<0.01). Moreover, the experimental group showed greater declines than the control group (P<0.05). The serum levels of GRP78, Caspase-3,and TGF-β1 and the urinary level of TGF-β1 in DKD patients showed positive correlations with BUN, SCr, UACR, and FBG and negative correlations with eGFR (P<0.05). ④ Safety outcomes: Neither group showed drug-related adverse reactions, and laboratory safety parameters remained within normal ranges. ConclusionYishen Jiangtang decoction combined with conventional Western medicine treatment may safely and effectively alleviate clinical symptoms, correct glucose and lipid metabolism disorders, and protect the renal function in patients with stage G3A3 DKD and the pattern of Qi-Yin deficiency combined with dampness-heat and blood stasis. The mechanism may be associated with inhibition of the ERS-apoptosis axis and delay of the RF process.

OBJECTIVE:
This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study.
METHODS:
A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants.
RESULTS:
Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m 2) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m 2) and obesity (≥ 28.0 kg/m 2) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m 2 ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses.
CONCLUSION
This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Lung cancer poses a serious threat to global public health security.Chemotherapy,as the main strategy for cancer treatment,faces challenges such as high toxicity and drug resistance.Anticancer peptides have the potential of being developed into new anticancer drugs due to their advantages of broad-spectrum anticancer activity,rapid action,and difficulty in generating drug resistance,but they also face shortcomings such as weak activity and strong toxic side effects.The weakly acidic microenvironment of tumors(pH 6.5-6.8)provides a good idea for the design of anticancer peptides of high-efficiency and low-toxicity.Previously,we designed the acid-sensitive antibacterial peptide pHly-1 using the wolf spider(Lycosa singoriensis)toxin Lycosin-Ⅰ as a template.In this study,we found that pHly-1 also had acid-sensitive anticancer activity.Further alanine scanning analysis of pHly-1 was carried out,and we ob-tained a mutant pHTP-2 with better acid sensitivity,whose IC50(half maximal inhibitory concentration)against A549 cells was 15.68 μmol/L at pH 6.6 and was greater than 100 μmol/L at pH 7.4.At pH 6.6,pHTP-2 could act on various lung cancer cell lines and induce the death of A549 cells by rapid ly-sis;at pH 7.4,500 μmol/L pHTP-2 had weak toxicity to red blood cells(the hemolysis rate was ap-proximately 38%)and primary myocardial cells(the inhibition rate was 49.7%,with P<0.05).Analy-sis of its charge,particle size,morphology,and secondary structure showed that at pH 6.6,the histidine in the sequence of pHTP-2 was protonated,increasing the positive charge(P<0.01),decreasing the hy-drated particle size(P<0.05)and forming an α-helical structure to induce membrane lysis of A549 cells.At pH 7.4,it was deprotonated,the positive charge decreases,a β-sheet structure was formed and self-aggregation occurred,limiting its effect on the A549 cell membrane and showing weak activity.In summary,pHTP-2 could respond to the weakly acidic microenvironment of tumors to exert selective cyto-toxic activity,effectively overcoming the shortcomings of anticancer peptides such as low efficiency and high toxicity.Our findings suggest that it is a high-quality lead molecule for anticancer drugs.

The Lambl's excrescences(LEs)are elongated valvular fronds with excessive mobility,commonly found at the closure lines of heart valves.These filiform projections are thin and long,exhibiting undulating independent motion.LEs predominantly occur on the ventricular side of the aortic valve and on the atrial side of the mitral valve,although there have been documented cases involving tricuspid,pulmonic,and prosthetic valves.To detect LEs,transesophageal echocardiography is often recommended.The high stress experienced by left-sided valves during closure can lead to tears or lesions in the endocardium that initiate LEs pathogenesis.In this particular case study,we present a patient who presented with acute non-ST-segment elevation myocardial infarction alongside LEs located on the non-coronary cusp of the aortic valve.This specific anatomical location posed significant challenges during percutaneous coronary intervention(PCI),as it required direct contact between the guiding catheter and the aortic valve,thereby increasing the risk of dislodging the LEs.Fortunately,our team successfully performed PCI without encountering any notable complications or embolic events.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.
