Myocardial fibrosis is a serious cause of heart failure and even sudden cardiac death. However, the mechanisms underlying myocardial ischemia-induced cardiac fibrosis remain unclear. Here, we identified that the expression of sterile alpha and TIR motif containing 1 (SARM1), was increased significantly in the ischemic cardiomyopathy patients, dilated cardiomyopathy patients (GSE116250) and fibrotic heart tissues of mice. Additionally, inhibition or knockdown of SARM1 can improve myocardial fibrosis and cardiac function of myocardial infarction (MI) mice. Moreover, SARM1 fibroblasts-specific knock-in mice had increased deposition of extracellular matrix and impaired cardiac function. Mechanically, elevated expression of SARM1 promotes the deposition of extracellular matrix by directly modulating P4HA1. Notably, by using the Click-iT reaction, we identified that the increased expression of ZDHHC17 promotes the palmitoylation levels of SARM1, thereby accelerating the fibrosis process. Based on the fibrosis-promoting effect of SARM1, we screened several drugs with anti-myocardial fibrosis activity. In conclusion, we have unveiled that palmitoylated SARM1 targeting P4HA1 promotes collagen deposition and myocardial fibrosis. Inhibition of SARM1 is a potential strategy for the treatment of myocardial fibrosis. The sites where SARM1 interacts with P4HA1 and the palmitoylation modification sites of SARM1 may be the active targets for anti-fibrosis drugs.

This paper summarized Professor LI Yueqing's clinical experience in treating prostate cancer by stages from the perspective of deficiency and stasis. It is believed that the onset of prostate cancer is due to kidney deficiency， while blood stasis is the core pathogenesis， and dampness-heat， phlegm-turbid， and cancer toxins are the key pathological factors in the progression of the disease. The pathogenesis in the early stage of the disease is kidney qi depletion and dampness， heat and phlegm coagulation； in the middle stage， it is spleen and kidney depletion， phlegm coagulation and blood stasis； and in the late stage， the pathogenesis changes into yin deficiency and essence depletion， and stasis-turbid toxin obstruction. For treatment， the basic principle is to supplement and boost kidney qi， enrich and nourish the kidney yin. The main treatment methods are draining dampness， dissolving phlegm， dispelling stasis， clearing heat and resolving toxins， and the method of invigorating blood and dispelling stasis runs through the whole course of treatment. In the early stage， radical treatment is mainly used， and Longshe Yangquan Decoction （龙蛇羊泉汤） with modifications is supplemented to clear and drain dampness and heat. In the middle stage， androgen deprivation therapy is the basic treatment， and Bushen Tongqiao Decoction （补肾通窍汤） with modifications is used in combination to nourish the spleen and kidney， dissolve phlegm and dispel stasis. In the late stage， Dabuyin Pills and Liuwei Dihuang Pills （大补阴丸合六味地黄丸） with modifications is mainly used to enrich yin and supplement essence， resolve toxins and dissolve stasis， and prevent cancer recurrence.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective To determine the effects of treadmill training on the structure of hippocampal myelin and cognitive function in rats exposed to acute plateau hypoxia.Methods With 30 SPF-grade female SD rats (aged 6-8 weeks,weighing 200-220 g),6 of them were used for observation of myelin structure after injury,and the remaining 24 rats were randomly divided into control group,hypobaric hypoxia group and treadmill training group (n=8).The rats in above experimental groups were placed in a low-pressure oxygen chamber at an altitude of 6000 m for 7 consecutive days,and the rats of the control group were placed in the confined chamber for the same period without hypoxia.Then,the rats of the treadmill training group received a 4-week treadmill training scheme since the day after hypoxia.Finally,all the rats were tested for cognitive function with open field test (OFT)and Morris water maze (MWM).Transmission electron microscopy (TEM) was used to observe the changes of demyelination in the hippocampus. The expression of oligodendrocyte transcription factor 2 (Olig2)and myelin basic protein (MBP )in the hippocampal CA1 and CA3 regions was measured by immunofluorescence staining and Western blotting.Results Behavioral tests showed that the number into the central area,total distance,distance ratio in OFT and the number of platform crossings and distance to the target area in MWM were reduced in the hypobaric hypoxia group than the control group (P<0.05 ),while these indexes were increased in the treadmill training group than in the hypobaric hypoxia group (P<0.05).Immunofluorescence staining indicated that the number of Olig2 positive cells per unit area and the mean fluorescence intensity of MBP in the CA1 and CA3 regions were significantly lessen in the hypobaric hypoxia group than the control group (P<0.05 ),while these indicators were higher in the treadmill training group than the hypobaric hypoxia group (P<0.05 ).Western blotting displayed that the expression levels of Olig2 and MBP in the hippocampus were obviously lower in the hypobaric hypoxia group than the control group (P<0.01 ),while the levels were increased in the treadmill training group than the hypobaric hypoxia group (P<0.01 ).Conclusion Treadmill training promotes the number of the oligodendrocyte spectrum cells in CA1 and CA3 regions,enhances the expression of myelin-related proteins and improves myelin repair in hippocampus of hypobaric hypoxia rats,and thereby ameliorates hypoxia-induced anxiety-like behaviors and memory dysfunction.

Cancer， one of the deadliest diseases caused by cells escaping homeostasis， abnormal proliferation， and abnormal differentiation， is fast becoming one of the most burdensome diseases of this century. With decades of human research and cognitive changes in cancer， cancer treatment is also developing rapidly， but there is still a lack of effective treatment and countermeasures. Especially， the search for safe， efficient， and non-toxic drugs has become a long-term goal in the field of cancer. Saponins extracted and separated from traditional Chinese medicine can improve cancer through various pathways and have almost no toxic side effects. Therefore， the research on the anti-cancer effect of saponins is heating up. It is found that saponins play anti-tumor roles by inhibiting proliferation， metastasis， and angiogenesis of cancer cells， promoting apoptosis of cancer cells， inducing autophagy of tumor cells， and regulating miRNA expression and immune functions. Chinese herbal medicine saponins can regulate secretory glycoprotein /β-catenin （Wnt/β-catenin）， adenylate activated protein kinase （AMPK）， nuclear transcription factor-κB （NF-κB）， mitogen-activated protein kinase （MAPK）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， Janus kinase/activator of signal transduction and transcription 3 （JAK/ STAT3）， hypoxia-inducible factor-1α （HIF-1α）， Toll-like receptor （TLR）， and other related signaling pathways to get involved in the proliferation， metastasis， angiogenesis， apoptosis， autophagy， and other processes of cancer cells， thus interfering with the progression of cancer. Therefore， the focus of this review is to update the discovery and evaluation of Chinese herbal medicine saponins with anti-cancer properties， clarify their mechanism of action， including the progress of related signaling pathways， and deepen the understanding of the anti-cancer function of Chinese herbal medicine saponins， so as to provide a new perspective and direction for the prevention and treatment of tumors by traditional Chinese medicine and better promote the development and utilization of resources.

Objective To investigate the risk factors associated with necrosis in interstitial oedematous pancreatitis(IOP)and to develop a nomogram model for the early prediction of necrosis in IOP.Methods A retrospective analysis was conducted on 306 patients diagnosed with IOP.Patients were stratified into necrosis and edema groups based on the presence or absence of pancreatic necrosis through follow-up CT-enhanced examinations.Logistic regression analysis was employed to identify independent predictive factors for necrosis in IOP.Subsequently,a nomogram model was developed,and its discriminative ability,accuracy,and practicality were assessed through receiver operating characteristic(ROC)curve,calibration curve,and decision curve analysis(DCA).Results Balthazar computed tomography severity index(CTSI),gender,lactate dehydrogenase(LDH),and triglyceride(TG)were finally identified as four independent predictors for constructing the nomogram model.The area under the curve(AUC)of the nomogram model was 0.800[95％confidence interval(CI)0.731-0.869].The calibration curve indicated good consistency between the predicted probabil-ity and the actual probability of necrosis in IOP(P=0.737).DCA suggested high practicality of the nomogram model within the threshold probability range of 3％to 66％and 75％to 96％.Conclusion The nomogram model based on Balthazar CTSI,gender,LDH,and TG demonstrates good efficacy in early prediction of necrosis in IOP.

Objective:To investigate the prognostic factors for all-cause mortality in patients with muscle-invasive bladder cancer(MIBC)with intermediate-to-high-risk primary prostate cancer.Methods:From January 2012 to October 2023,the clinical data of the patients with MIBC with intermediate-to-high-risk primary prostate cancer in Peking University Third Hospital were retrospectively analyzed.All the patients were monitored and the occurrence of all-cause death was documented as the outcome event in the prognostic study.Univariate and multivariate Cox proportional risk regression analysis models were implemented to search for independent influences on the prognosis of patients.For significant influencing factors(pathological T stage,M stage and perineural invasion of bladder cancer),survival curves were plotted before and after multifactorial Cox regression adjusting for confounding factors.Results:A total of 32 patients were included in this study.The mean age was(72.5±6.6)years;the median preoperative total prostate specific antigen(tPSA)was 6.68(2.47,6.84)μg/L;the mean preoperative creatinine was(95±36)μmol/L,and the median survival time was 65 months.The majority of the patients(87.5％)had high-grade bladder cancer,53.1％had lymphatic invasion,and 31.3％had perineural invasion.Prostate involvement was observed in 25.0％of the cases,and the positive rate of soft-tissue surgical margin was 37.5％.Multivariate Cox analysis revealed that preoperative creatinine level(HR=1.02,95％CI:1.01-1.04),pathological stage of bladder cancer T3(HR=11.58,95％CI:1.38-97.36)and T4(HR=19.53,95％CI:4.26-89.52)metastasis of bladder cancer(HR=9.44,95％CI:1.26-70.49)and perineural invasion of bladder cancer(HR=6.26,95％CI:1.39-28.27)were independent prognostic factors(P＜0.05).Survival curves with Log-rank test after adjusting for confounding factors demonstrated that bladder cancer pathology T3,T4,M1,and perineural invasion were unfavorable factors affecting the patients'survival prognosis(P＜0.05).Conclusion:Patients with MIBC with intermediate-to-high risk primary prostate cancer generally portends a poor prognosis.High preoperative serum creatinine,T3 or T4 pathological stage of bladder cancer,metastasis of bladder cancer and bladder cancer perineural invasion are poor prognostic factors for patients with MIBC with intermediate-to-high risk primary prostate cancer.

Vesicular glutamate transporter 2(VGlut2)is expressed in the PVN of the hypothalamic paraventricular nucleus(PVNVG1ut2)as an excitatory neurotransmitter,which regulates food intake and energy metabolism and plays an important role in maintaining homeostasis.However,it is not clear that the upstream and downstream projection network of PVNVGut2 neurons hinders the anal-ysis of glutamatergic neuron circuit function.Anterograde and retrograde tracer viruses were injec-ted into the PVN of VGlut2 mice by stereotactic brain injection technique to find the input and output nuclei of PVNVGlut2 neurons.Anterograde tracing results showed that PVNVGlut2 neurons pro-jected to the downstream medial amygdala(MeAD)and arcuate nucleus(ARC).Retrograde trac-ing results showed that PVNVGlut2 received input from the prefrontal nucleus(Pr),the reticular tegmental nucleus(RtTg),and the hypoglossal nucleus(12N).In addition,VGlut2 was found to be co-expressed with neuronal nitric oxide synthase(nNOS)neurons in the PVN.The anatomical net-work of PVNVG1ut2 neurons was analyzed by virus tracking tool,which laid the anatomical founda-tion for further study on the functional regulation of PVNVGlut2.

Bone organoids can simulate the complex structure and function of the bone tissues, which makes them a frontier technology in organoid researches. Bone organoids show a tremendous potential of applications in bone disease modeling, bone injury repair, and medicine screening. Although advancements have been made so far in constructing bone organoids with functional structures like mineralization, bone marrow, trabecular bone, callus, woven bone, etc, the researches in this field are confronted with numerous challenges such as lack of standardized construction strategies and unified evaluation criteria, which limits their further promotion and application. To standardize researches in bone organoids, the Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, the Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, the Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and the Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine organized related experts to formulate Expert consensus on the construction, evaluation, and application of bone organoids ( version 2024) based on an evidence-based approach. A total of 17 recommendations were put forth, aiming to standardize researches and clinical applications of bone organoids and enhance their value in scientific research and clinical practice.

Diabetic retinopathy （DR） is one of the most common chronic microvascular complications of diabetes mellitus. It has a high rate of blindness， and the age of onset is gradually getting younger， which seriously affects the physical and mental health and quality of life of patients. The disease is retinal damage induced by diabetes mellitus， which is a kind of fundus disease with the main manifestations of fundus hemorrhage， hard exudation， microhemangioma， cotton-wool spots， neovascularization， etc. In traditional Chinese medicine （TCM）， it is classified into the category of "diabetic cataracts" and other diseases. At present， there is no effective method to prevent the progress of the disease in modern medicine， so it is particularly important to choose a reasonable and effective intervention to prevent and treat DR. Studies have confirmed that TCM has unique advantages in the treatment of DR. It can use its advantages of multiple bioactive components， multiple targets， and multiple pathways to intervene in the development process of DR from various aspects. By searching for the relevant literature on the progress of the intervention of DR with TCM monomers and compounds， this paper mainly reviews the relevant research results of the treatment of DR with multiple signaling pathways such as phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）， nuclear factor kappa-B（NF-κB）， p38 mitogen-activated protein kinase （p38 MAPK）， nuclear factor erythroid 2-related factor （Nrf2）/hemeoxygenase-1 （HO-1）， Hippo， advanced glycation end products （AGEs）/receptor for advanced glycation end products （RAGE）， and Akt/glycogen synthase kinase-3β （GSK-3β）， so as to provide more ideas and directions for the clinical prevention and treatment of DR.
