Diabetic kidney disease（DKD） is a chronic kidney structural and functional disorder caused by diabetes. With the global prevalence of diabetes continuing to rise， DKD has gradually become a major cause of chronic kidney disease and end-stage renal disease（ESRD）， posing a serious threat to patients' quality of life and long-term health outcomes. Studies have shown that apoptosis plays a pivotal role in the development and progression of DKD， with its mechanisms involving abnormal activation of multiple signaling pathways such as Toll-like receptor 4（TLR4）/nuclear transcription factor-κB（NF-κB）/B-cell lymphoma-2（Bcl-2）/cysteinyl aspartate-specific proteinase（Caspase）-3， protein kinase R-like endoplasmic reticulum kinase（PERK）/eukaryotic initiation factor 2α（eIF2α）/activating transcript factor 4（ATF4）/CCAAT enhancer-binding protein homologous protein（CHOP）， phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt）/glycogen synthase kinase-3β（GSK-3β）， Janus kinase 2（JAK2）/signal transducer and activator of transcription 3（STAT3）， adenosine monophosphate-activated protein kinase（AMPK）/mammalian target of rapamycin（mTOR） and silent information regulator 1（SIRT1）/tumor suppressor protein 53（p53）， thereby accelerating renal pathological damage in DKD. Extensive evidence-based medical studies have confirmed that traditional Chinese medicine（TCM）， leveraging its unique therapeutic advantages of multi-target， multi-component and multi-pathway approaches， has demonstrated remarkable efficacy and favorable safety profiles in treating DKD. Recent studies have demonstrated that active components of TCM can specifically target and modulate key effectors in apoptotic signaling pathways. Meanwhile， traditional compound formulations exert synergistic effects through multiple approaches such as replenishing deficiency and activating blood circulation， detoxifying and dredging collaterals， tonifying kidney essence， and removing stasis and purging turbidity， thereby comprehensively regulating critical pathological processes including endoplasmic reticulum stress and mitochondrial apoptosis pathways. This combined therapeutic approach of molecular targeting and holistic regulation provides novel strategies for delaying the progression of DKD. Based on this， this paper provides an in-depth analysis of key apoptotic signaling pathways and their regulatory mechanisms， while systematically summarizing recent research advances regarding the therapeutic effects of TCM active components， compound formulations， and proprietary Chinese medicines on DKD through modulation of these pathways， with particular emphasis on their underlying molecular mechanisms. These findings not only elucidate the modern scientific connotation and theoretical basis of TCM in treating DKD but also establish a solid theoretical and practical foundation for promoting the wider clinical application and further research of TCM in the field of DKD treatment.

Objective:To explore the clinical symptoms, imaging characteristics, cerebrospinal fluid (CSF) features, as well as the treatment and prognosis of autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy.Methods:Sixty-one patients with anti-GFAP astrocyte antibody (GFAP-IgG) single-positive autoimmune encephalitis who were treated at the Third Affiliated Hospital, Sun Yat-sen University between January 2017 and September 2023 were retrospectively collected. The demographic characteristics (age at onset, sex), clinical symptoms (core symptoms, neurological deficits, psychiatric behavioral abnormalities, and autonomic dysfunction), imaging features [brain/spinal cord/optic nerve magnetic resonance imaging (MRI) lesion distribution and enhancement patterns], and CSF parameters were analyzed. Acute-phase treatments, including methylprednisolone pulse therapy, intravenous immunoglobulin (IVIG), etc, along with the follow-up outcomes [modified Rankin Scale (mRS) score] were recorded.Results:The onset age was 40 (30, 55) years, and 68.9% (42/61) of the patients were male. The most common clinical manifestations were fever (65.6%, 40/61), headache (60.7%, 37/61), and urinary/defecatory abnormalities (45.9%, 28/61). Brain MRI revealed lesions predominantly in the cerebral cortex and subcortical white matter (57.4%, 35/61), periventricular white matter (50.8%, 31/61), and basal ganglia (36.1%, 22/61). Periventricular linear-radiating enhancement was the predominant MRI enhancement pattern (55.7%, 34/61). Spinal MRI showed lesions mainly in the cervical (42.6%, 26/61) and thoracic spinal cord (32.8%, 30/61), with leptomeningeal enhancement (31.1%, 19/61) and scattered punctate/patchy enhancements (21.3%, 13/61). Optic neuropathy was observed in 6 cases (9.8%). CSF analysis demonstrated a pressure of 180 (133, 240) mmH 2O (1 mmH 2O=0.009 8 kPa), white blood cell count of 29 (4, 156)×10?/L, and protein level of 0.72 (0.40, 1.44) g/L. Nineteen patients (31.1%) experienced rapid progression of meningoencephalitis or myelitis within 3 days of admission. All patients received methylprednisolone pulse therapy, with 47.5% (29/61) additionally treated with IVIG. At a follow-up of 12 (3, 28) months, 12 cases (19.7%) relapsed, and 75.4% (46/61) had favorable outcomes (mRS score 0-2). Poor prognosis (mRS score>2) was observed in 4 cases, including 3 with cervical spinal cord involvement and status epilepticus, 1 elderly patient with lung cancer. Conclusions:GFAP astrocytopathy predominantly affects young adults, with a male predominance. Spinal cord involvement is common, manifesting as myelitis and myelopathy. Rapid progression of meningoencephalitis or myelitis may occur early in the disease course. Periventricular linear-radiating enhancement on brain MRI is a key diagnostic clue. Leukocyte and protein levels in the cerebrospinal fluid are generally mildly to moderately elevated. Most patients respond well to corticosteroids and immunotherapy, with favorable outcomes. However, advanced age and cervical spinal cord involvement are associated with poor prognosis.

Objective:This study aims to systematically compare the differences in severity, clinical manifestations, and treatment processes between patients with foodborne and iatrogenic botulism, thereby providing evidence-based support for clinical diagnosis and management.Methods:A retrospective analysis was conducted on botulism patients admitted to the Second Hospital of Hebei Medical University between January 2010 and July 2024. The foodborne group was diagnosed according to the WS/T 83-1996 standard. The iatrogenic group required a documented history of type A botulinum toxin injection and typical clinical manifestations. Individuals with comorbid neurological disorders or incomplete clinical data were excluded. The severity of poisoning was classified into three groups: mild, moderate, and severe, according to the "Diagnosis and Treatment Protocol for Botulism". SPSS 26.0 software was used to statistically analyze the distribution of poisoning severity between groups and to compare clinical symptoms and course indicators across severity grades.Results:A total of 220 botulism patients were included in this study, comprising 86 cases of foodborne poisoning (39.1%) and 134 cases of iatrogenic poisoning (60.9%). There was a significant difference in the distribution of poisoning severity between the two groups ( P=0.001), the proportion of severe poisoning was significantly higher in the foodborne group. Analysis of clinical symptoms indicated that, among patients with mild poisoning, the incidence of nausea and vomiting was significantly higher in the foodborne group, compared to that in the iatrogenic group (44.0% vs. 16.4%, P=0.006). In patients with moderate poisoning, the iatrogenic group exhibited a significantly higher prevalence of hoarseness (60.5% vs. 35.7%, P=0.041) and neck weakness (53.5% vs. 17.9%, P=0.003) compared to the foodborne group. Conversely, the foodborne cohort experienced a notably longer interval before seeking medical attention when compared to their iatrogenic counterparts (2.25 d vs. 1.50 d, P=0.003). Among severe poisoning patients, the foodborne group exhibited a higher likelihood of experiencing fever (51.5% vs. 25.0%, P=0.044) and abdominal distension accompanied by constipation (69.7% vs. 41.7%, P=0.034) when compared to the iatrogenic group. Furthermore, the foodborne cohort demonstrated a significantly shorter incubation period (1.00 d vs. 2.45 d, P<0.001), an extended length of hospitalization (22.0 d vs. 16.00 d, P=0.001), and a prolonged duration of antitoxin therapy (14.00 d vs. 9.50 d, P<0.001), alongside a markedly higher total dosage administered (315 900 U vs. 163 300 U, P<0.001) compared to their iatrogenic counterparts. Conclusions:Statistically significant differences exist between food-borne and iatrogenic botulism. Food-borne botulism is characterized by acute onset, greater severity, and a prolonged course, predominantly featuring systemic symptoms and gastrointestinal dysfunction. In contrast, iatrogenic botulism primarily manifests with ocular and oropharyngeal muscle symptoms and is generally less severe.

Hepatic encephalopathy is a difficult and critical disease with rapid progression and limited treatment methods in the field of liver disease， and it is urgently needed to make breakthroughs in its pathogenesis. Selection of appropriate prevention and treatment strategies is of great importance in delaying disease progression and reducing the incidence and mortality rates. This article reviews the theory of “turbid toxin pathogenesis” and related prevention and treatment strategies for hepatic encephalopathy in traditional Chinese medicine/Zhuang medicine， proposes a new theory of “turbid toxin pathogenesis”， analyzes the scientific connotations of “turbid”， “toxin”， and the theory of “turbid toxin pathogenesis”， and constructs the “four-step” prevention and treatment strategies for hepatic encephalopathy， thereby establishing the new clinical prevention and treatment regimen for hepatic encephalopathy represented by “four prescriptions and two techniques” and clarifying the effect mechanism and biological basis of core prescriptions and techniques in the prevention and treatment of hepatic encephalopathy， in order to provide a reference for the prevention and treatment of hepatic encephalopathy.

Objective To investigate the impact of SARS-CoV-2 infection on male semen quality through meta-analysis and retrospec-tive study.Methods Literature retrieval was conducted in PubMed,CNKI,Wanfang Database and CBM database.Meta-analysis was performed using Stata 15.0.The male patients meeting the inclusion criteria from our hospital were enrolled as study subjects.General demographic data and semen parameters were collected.Single factor analysis of variance and graphing of semen parameters were con-ducted using GraphPad Prism 9.5.1.The test level was set at 0.05.Results A total of 9 studies involving 267 patients were included in the meta-analysis.There were no significant differences in sperm concentration and survival rate before and after SARS-CoV-2 infec-tion(P＞0.05).Semen volume and percentage of normal morphology significantly increased during 1-3 months after infection(P=0.005,P=0.010),with semen volume recovering to pre-infection level＞3 months later(P＞0.05).Sperm motility and progressive mo-tility increased＞3 months after infection(P=0.046,P=0.045),recovering to pre-infection levels(P=0.099,P=0.098).Sperm DNA fragmentation index may be temporarily elevated within 3 months after infection but gradually decreased＞3 months later.In the retrospective study of 8 cases,there were no statistical differences in semen parameters at different stages compared with pre-infection(P＞0.05),but semen parameters showed a negative trend during＜1 month after infection and recovered to pre-infection levels＞3 months later.Conclusion The results of this laboratory study are basically consistent with the meta-analysis.SARS-CoV-2 infection in males only caused short-term negative effects on sperm morphology,vitality and DNA integrity,but generally recovered to pre-infection levels＞3 months after infection.Due to the limitations of study subjects and sample size,the impact of SARS-CoV-2 infection on male semen quality needs to be further confirmed by long-term large-scale prospective studies.

BACKGROUND:Early identification of patients requiring ventilator support will be beneficial for the outcomes of botulism.The present study aimed to establish a new scoring system to predict mechanical ventilation(MV)for botulism patients. METHODS:A single-center retrospective study was conducted to identify risk factors associated with MV in botulism patients from 2007 to 2022.Univariate analysis and multivariate logistic regression analysis were used to screen out risk factors for constructing a prognostic scoring system.The area under the receiver operating characteristic(ROC)curve was calculated. RESULTS:A total of 153 patients with botulism(66 males and 87 females,with an average age of 43 years)were included.Of these,49 patients(32.0%)required MV,including 21(13.7%)with invasive ventilation and 28(18.3%)with non-invasive ventilation.Multivariate analysis revealed that botulinum toxin type,pneumonia,incubation period,degree of hypoxia,and severity of muscle involvement were independent risk factors for MV.These risk factors were incorporated into a multivariate logistic regression analysis to establish a prognostic scoring system.Each risk factor was scored by allocating a weight based on its regression coefficient and rounded to whole numbers for practical utilization([botulinum toxin type A:1],[pneumonia:2],[incubation period≤1 day:2],[hypoxia<90%:2],[severity of muscle involvement:grade II,3;grade III,7;grade IV,11]).The scoring system achieved an area under the ROC curve of 0.82(95%CI 0.75-0.89,P<0.001).At the optimal threshold of 9,the scoring system achieved a sensitivity of 83.7%and a specificity of 70.2%. CONCLUSION:Our study identified botulinum toxin type,pneumonia,incubation period,degree of hypoxia,and severity of muscle involvement as independent risk factors for MV in botulism patients.A score≥9 in our scoring system is associated with a higher likelihood of requiring MV in botulism patients.This scoring system needs to be validated externally before it can be applied in clinical settings.

End-stage liver diseases,such as cirrhosis and liver cancer caused by hepatitis B,are often combined with hepatic encephalopathy(HE);ammonia poisoning is posited as one of its main pathogenesis mechanisms.Ammonia is closely related to autophagy,but the molecular mechanism of ammonia's regulatory effect on autophagy in HE remains unclear.Sialylation is an essential form of glycosylation.In the nervous system,abnormal sialylation affects various physiological processes,such as neural development and synapse formation.ST3 β-galactoside α2,3-sialyltransferase 6(ST3GAL6)is one of the significant glycosyltransferases responsible for adding α2,3-linked sialic acid to substrates and generating glycan structures.We found that the expression of ST3GAL6 was upregulated in the brains of mice with HE and in astrocytes after ammonia induction,and the expression levels of α2,3-sialylated glycans and autophagy-related proteins microtubule-associated protein light chain 3(LC3)and Beclin-1 were upregulated in ammonia-induced astrocytes.These findings suggest that ST3GAL6 is related to autophagy in HE.Therefore,we aimed to determine the regulatory relationship between ST3GAL6 and autophagy.We found that silencing ST3GAL6 and blocking or degrading α2,3-sialylated glycans by way of Maackia amurensis lectin-Ⅱ(MAL-Ⅱ)and neuraminidase can inhibit autophagy.In addition,silencing the expression of ST3GAL6 can downregulate the expression of heat shock protein β8(HSPB8)and Bcl2-associated athanogene 3(BAG3).Notably,the overexpression of HSPB8 partially restored the reduced autophagy levels caused by silencing ST3GAL6 expression.Our results indicate that ST3GAL6 regulates autophagy through the HSPB8-BAG3 complex.
