Acute pancreatitis(AP)is a frequently encountered acute abdominal syndrome in clinical settings,and the integrated model of traditional Chinese and Western medicine(TCM-WM)has demonstrated notable advantages in the diagnosis and treatment of AP.To systematize and standardize clinical practices related to develop clinical pathway for integrated TCM-WM diagnosis and treatment of AP,which enhances the efficiency and quality of patient care.This pathway focuses on AP,a common acute and life-threatening disease within the digestive system,and outlines that the central pathological mechanism involves pancreatic injury and localized inflammation resulting from the abnormal activation of pancreatic enzymes.It has the characteristics of rapid onset,multiple causes,and complex manifestations.Severe cases can be life-threatening.At present,conventional treatments encompass a diverse range of modalities.Moreover,traditional Chinese medicine(TCM)holds distinct advantages in alleviating relevant symptoms,and TCM-WM is gaining increasing prevalence.To enhance the standardization and consistency of diagnostic and therapeutic practices,this clinical pathway clearly delineates the target patient population,which includes individuals diagnosed with abdominal pain disorder according to TCM and with AP in accordance with WM criteria,as well as the corresponding inclusion standards.The diagnostic framework integrates both TCM and WM guidelines,and further incorporates disease staging,severity grading,and syndrome differentiation to support a comprehensive and integrated diagnostic strategy.The treatment integrates approaches from both TCM and WM.Within the WM framework,interventions consist of basic supportive care,infection control,nutritional support,and the management of complications.In the context of TCM,the protocol includes syndrome differentiation and corresponding therapeutic strategies(Distinct syndrome patterns are identified and managed during the acute and convalescent phases),such as acupuncture and retention enema.This clinical pathway addresses multiple key components,including preventive strategies,post-treatment follow-up,criteria for evaluating therapeutic efficacy,admission and discharge,admission examination protocols,discharge criteria,and the rationale for deviations or withdrawal from the pathway.It is designed to provide a systematic and standardized reference framework for relevant clinical practices.

Objective:To explore the expressions and significance of nucleotide binding oligomerization domain-like receptor protein 3 (NLRP3), cysteinyl aspartate specific proteinase-1 (Caspase-1) and interleukin-1β (IL-1β) in patients with hemorrhagic stroke.Methods:One hundred and three patients with hemorrhagic stroke who visited the Department of Neurosurgery of the Second Affiliated Hospital of Zhengzhou University from January 2022 to January 2024 were selected as the hemorrhage group.Another 90 healthy individuals who underwent physical examinations were selected as the control group.The differences in the levels of NLRP3, Caspase-1 and IL-1β in peripheral blood between the two groups were compared. The National Institutes of Health neurological deficiency score (NHISS) was used to evaluate the degree of neurological deficits of patients in the hemorrhage group. All patients were followed up for 3 months. The prognosis of patients was evaluated by modified Rankin scale (mRS). The statistical analysis was performed using SPSS 20.0 software. The relationship between peripheral blood indexes and blood loss, severity of neurological impairment was analyzed by Spearman correlation analysis. The predictive value of peripheral blood indexes for prognosis was evaluated by receiver operating characteristic (ROC) curves.Results:The expression levels of NLRP3 mRNA (2.67±0.42, 1.04±0.28), Caspase-1 mRNA (1.24±0.26, 0.75±0.14) and IL-1β protein ((24.92±4.97) pg/mL, (13.39±2.35) pg/mL) in the hemorrhage group were higher than those in the control group ( t=31.243, 15.967, 20.126, all P<0.05). When comparing the levels of NLRP3 mRNA, Caspase-1 mRNA and IL-1β in the peripheral blood of patients with different amounts of bleeding, those with massive bleeding were higher than those with moderate bleeding, and those with moderate bleeding were higher than those with mild bleeding (all P<0.05).The Spearman correlation analysis showed that the levels of NLRP3 mRNA, Caspase-1 mRNA and IL-1β in peripheral blood were positively correlated with the amount of bleeding in patients with hemorrhagic stroke ( r=0.646, 0.585, 0.604, all P<0.05). The levels of NLRP3 mRNA, Caspase-1 mRNA and IL-1β in patients with severe neurological deficits were higher than those in patients with moderate and mild neurological deficits, and those in patients with moderate neurological deficits were higher than those in patients with mild neurological deficits (all P<0.05). The results of Spearman correlation analysis showed that the levels of NLRP3 mRNA, Caspase-1 mRNA and IL-1β in peripheral blood were positively correlated with the degree of neurological deficits in patients with hemorrhagic stroke ( r=0.607, 0.522, 0.546, all P<0.05). The expression levels of NLRP3 mRNA, Caspase-1 mRNA and IL-1β in peripheral blood in the poor prognosis group were higher than those in the good prognosis group (all P<0.05). The prediction results indicated that bleeding into the cerebral ventricles, large amount of bleeding, and high expression of NLRP3, Caspase-1 and IL-1β in peripheral blood were independent risk factors for poor prognosis in patients with hemorrhagic stroke (all P<0.05). The area under the ROC curve for the combined assessment of poor prognosis in hemorrhagic stroke by the levels of NLRP3 mRNA, Caspase-1 mRNA and IL-1β was 0.856, which was larger than the areas under the curves of the three indicators detected separately (0.720, 0.703, 0.715, P<0.05). Conclusion:The expressions of peripheral blood NLRP3, Caspase-1 and IL-1β are up-regulated in patients with hemorrhagic stroke, and their high expressions are related to blood loss and the severity of neurological deficit, which also indicate poor prognosis of patients.

Background::In vitro fertilization (IVF) has emerged as a transformative solution for infertility. However, achieving favorable live-birth outcomes remains challenging. Current clinical IVF practices in IVF involve the collection of heterogeneous embryo data through diverse methods, including static images and temporal videos. However, traditional embryo selection methods, primarily reliant on visual inspection of morphology, exhibit variability and are contingent on the experience of practitioners. Therefore, an automated system that can evaluate heterogeneous embryo data to predict the final outcomes of live births is highly desirable. Methods::We employed artificial intelligence (AI) for embryo morphological grading, blastocyst embryo selection, aneuploidy prediction, and final live-birth outcome prediction. We developed and validated the AI models using multitask learning for embryo morphological assessment, including pronucleus type on day 1 and the number of blastomeres, asymmetry, and fragmentation of blastomeres on day 3, using 19,201 embryo photographs from 8271 patients. A neural network was trained on embryo and clinical metadata to identify good-quality embryos for implantation on day 3 or day 5, and predict live-birth outcomes. Additionally, a 3D convolutional neural network was trained on 418 time-lapse videos of preimplantation genetic testing (PGT)-based ploidy outcomes for the prediction of aneuploidy and consequent live-birth outcomes.Results::These two approaches enabled us to automatically assess the implantation potential. By combining embryo and maternal metrics in an ensemble AI model, we evaluated live-birth outcomes in a prospective cohort that achieved higher accuracy than experienced embryologists (46.1% vs. 30.7% on day 3, 55.0% vs. 40.7% on day 5). Our results demonstrate the potential for AI-based selection of embryos based on characteristics beyond the observational abilities of human clinicians (area under the curve: 0.769, 95% confidence interval: 0.709–0.820). These findings could potentially provide a noninvasive, high-throughput, and low-cost screening tool to facilitate embryo selection and achieve better outcomes. Conclusions::Our study underscores the AI model’s ability to provide interpretable evidence for clinicians in assisted reproduction, highlighting its potential as a noninvasive, efficient, and cost-effective tool for improved embryo selection and enhanced IVF outcomes. The convergence of cutting-edge technology and reproductive medicine has opened new avenues for addressing infertility challenges and optimizing IVF success rates.

Objective:To investigate and analysis of the occurrence and influencing factors of sarcopenia in elderly critically ill patients in the intensive care unit (ICU).Methods:A prospective cohort study was conducted. Elderly patients (aged ≥ 60 years) admitted to the ICU of Tianjin Medical University General Hospital from November 2023 to June 2024 were enrolled. Clinical records were collected, and conduct muscle mass and strength measurements, as well as upper arm circumference and calf circumference were measured. Appendicular skeletal muscle index (ASMI) of less than 7.0 kg/m 2 for males and less than 5.7 kg/m 2 for females was defined as reduced muscle mass, grip strength of less than 28 kg for males and less than 18 kg for females was defined as decreased muscle strength, patients meeting both low muscle mass and low muscle strength criteria were diagnosed with sarcopenia. According to the diagnostic criteria for sarcopenia, patients were divided into sarcopenia group and non-sarcopenia group. Multivariate Logistic regression analysis was applied to identify risk factors for sarcopenia in the elderly and to develop a predictive model for the occurrence of sarcopenia. The predictive value of various risk factors for sarcopenia in elderly critically ill patients were evaluated by receiver operator characteristic curve (ROC curve). The Kaplan-Meier curve for the length of ICU stay of two groups patients were drawn. Results:Finally, 540 elderly critically ill patients were included, including 43 patients with sarcopenia, and the incidence of sarcopenia was 8.0%. Univariate analysis showed that there were significantly differences in body mass index (BMI), number of hospitalizations in the past year, the length of ICU stay, ventilation mode, duration of mechanical ventilation, pre-admission exercise habits, nutritional support methods, upper arm circumference, calf circumference, and albumin infusion between the sarcopenia group and the non-sarcopenia group. Multivariate Logistic regression analysis showed that BMI [odds ratio ( OR) = 0.79, 95% confidence interval (95% CI) was 0.67-0.93, P = 0.004], calf circumference ( OR = 0.64, 95% CI was 0.54-0.76, P < 0.001), and duration of mechanical ventilation ( OR = 1.06, 95% CI was 1.01-1.12, P = 0.034) were associated with an increased risk of sarcopenia in elderly critically ill patients. The ROC curve results showed that the area under the curve (AUC) and 95% CI of BMI, calf circumference, and duration of mechanical ventilation for predicting sarcopenia in elderly critically ill patients were 0.828 (0.767-0.888), 0.889 (0.844-0.933), and 0.397 (0.299-0.496), respectively, with cut-off values of 22.95 kg/m 2, 28.25 cm, and 50.50 days, respectively. The Kaplan-Meier curve showed that the cumulative survival rate of patients with sarcopenia was significantly lower than that of the non-sarcopenia group (Log-Rank test: χ 2 = 5.619, P = 0.018). Conclusion:Lower BMI, smaller calf circumference, and longer duration of mechanical ventilation are associated with an increased risk of sarcopenia in critically ill elderly patients.

We report a case of spinocerebellar ataxia type 8(SCA8)presenting with multisystem atrophic phenotype.The patient was a 57-year-old male with a 4-year course of illness with dizziness and ataxia as the first symptoms,followed by autonomic dysfunction and rapid eye movement sleep disorder.Neurological examination reveals autonomic dysfunction,nystagmus,dysarthria,ataxia,brain stem and cerebellar symmetrical atrophy and"hot cross bun"sign on MRI.The diagnosis of SCA8 was confirmed by the genetic testing which showed an abnormally high number of CTA/CTG repeats in the two alleles of the ATXN8OS.The patient responded well to symptomatic treatment such as ataxia and autonomic dysfunction.SCA8 is a rare movement disorder with high clinical heterogeneity.This report suggests that SCA8 can also present with autonomic dysfunction,ataxia,pontine"hot cross bun"sign and other characteristics similar to multisystem atrophy phenotype.Thus,it is necessary for clinicians to avoid misdiagnosis or missing the diagnosis of SCA8 presenting with multiple system atrophy cerebral type in clinical work.

Neuropathic pain is a chronic disease that severely afflicts the life and emotional status of patients, but currently available treatments are often ineffective. Novel therapeutic targets for the alleviation of neuropathic pain are urgently needed. Rhodojaponin VI, a grayanotoxin from Rhododendron molle, showed remarkable antinociceptive efficacy in models of neuropathic pain, but its biotargets and mechanisms are unknown. Given the reversible action of rhodojaponin VI and the narrow range over which its structure can be modified, we perforwmed thermal proteome profiling of the rat dorsal root ganglion to determine the protein target of rhodojaponin VI. N-Ethylmaleimide-sensitive fusion (NSF) was confirmed as the key target of rhodojaponin VI through biological and biophysical experiments. Functional validation showed for the first time that NSF facilitated trafficking of the Cav2.2 channel to induce an increase in Ca²⁺ current intensity, whereas rhodojaponin VI reversed the effects of NSF. In conclusion, rhodojaponin VI represents a unique class of analgesic natural products targeting Cav2.2 channels via NSF.

Objective:To evaluate the relationship between B-cell lymphoma/adenovirus E1B19 kDa-interacting protein 3-like protein (BNIP3L)/adenovirus E1B-interacting protein and mitochondrial dysfunction in the hippocampus of mice with sepsis-associated encephalopathy (SAE).Methods:One hundred and eighty C57BL/6J mice, aged 6-8 weeks, weighing 20-25 g, were divided into 4 groups ( n=45 each) using a random number table method: control group (C group), sham operation group (Sham group), SAE group, and SAE+ BNIP3L agonist carfilzomib group (SC group). The sepsis model was developed by cecal ligation and puncture (CLP) in anesthetized animals. In SC group, carfilzomib 2 mg/kg was intraperitoneally injected at 2 h after CLP. Twenty mice in each group were selected, and the survival at 7 days after operation was recorded. Eight surviving mice in each group were selected at 1 week after CLP for Morris water maze test. The remaining mice were sacrificed at 24 h after surgery, and the hippocampal tissues were harvested for determination of the expression of BNIP3L (by immunofluorescence) and BNIP3L in mitochondrial protein (by Western blot) and for microscopic examination of the morphological structure of mitochondria. The mitochondrial ATP content was measured by fluorescein-fluorescence enzyme luminescence method, and the mitochondrial membrane potential (MMP) was measured by fluorescence spectrophotometry. Results:Compared with C and Sham groups, the survival rate was significantly decreased, the escape latency was prolonged, the time of staying at the original platform quadrant was shortened, and the number of crossing the original platform region was decreased, the expression of BNIP3L in the hippocampal mitochondria was down-regulated, the MMP and content of mitochondrial ATP were decreased ( P<0.05), the intensity of fluorescence of BNIP3L in the hippocampus was decreased, and the damage to mitochondrial ultrastructure was marked in SAE group. Compared with SAE group, the survival rate was significantly increased, the escape latency was shortened, the time of staying at the original platform quadrant was prolonged, and the number of crossing the original platform region was increased, the expression of BNIP3L in the hippocampal mitochondria was up-regulated, the MMP and content of mitochondrial ATP were increased ( P<0.05), the intensity of fluorescence of BNIP3L in the hippocampus was decreased, and the damage to mitochondrial ultrastructure was attenuated in SC group. Conclusions:BNIP3L-mediated mitochondrial dysfunction may be involved in the mechanism of SAE developed in mice.

Objective:To identify the differentially expressed long-chain non-coding RNA(lncRNA) and mRNA using ribonucleic acid sequencing(RNA-seq), and construct a competing endogenous RNA(ceRNA) regulatory network in mice with sepsis-associated encephalopathy.Methods:Ten clean-grade healthy male C57BL/6 mice, aged 6-8 weeks, weighing 20-25 g, were divided into 2 groups( n=5 each) using a random number table method: sham operation group(group Sham) and sepsis group(group Sepsis). Sepsis was induced by cecal ligation and puncture(CLP) in group Sepsis, while group Sham only underwent laparotomy without CLP. Morris water maze test and contextual fear conditioning test were performed to detect the cognitive function on 1 day before CLP and 3 days after CLP. Three mice were randomly sacrificed in group Sham, and 3 mice with the worst results in the cognitive function test were sacrificed in group Sepsis. The hippocampal tissues were obtained for RNA-seq via the BGISEQ-500 platform, and the differentially expressed mRNA and lncRNA were identified. The differentially expressed mRNAs and lncRNAs were visualized and analyzed by Dr. Tom platform provided by Shenzhen BGI Technology Service Co., Ltd., and the ceRNA regulatory network was constructed using the online visualization tool Cytoscape software. Results:Compared with group Sham, the escape latency was significantly prolonged, and the percentage of time of staying at the target quadrants and percentage of time spent freezing were decreased in group Sepsis( P<0.05). A total of 62 differentially expressed lncRNAs were obtained from RNA-seq, of which the expression of 45 lncRNAs was up-regulated and the expression of 17 lncRNAs was down-regulated.There were 282 differentially expressed mRNAs identified from RNA-seq, of which the expression of 173 mRNAs was up-regulated, and the expression of 109 mRNAs was down-regulated.Gene Ontology enrichment analysis revealed that the differentially expressed mRNAs were involved in biological processes such as memory, learning or memory, inflammatory responses, regulation of aging-related behavioral decline, and regulation of synaptic plasticity. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that differentially expressed mRNAs were enriched in IL-17 signaling pathway, TNF signaling pathway, NF-κB signaling pathway and etc. KDA analysis was performed on the differentially expressed mRNAs to identify the key driver genes, and the results showed that Ch25h, Il6ra, Lcn2, Sgk1, Nr4a3, Osm, Saa3, Ccl7, Sqle, Dhcr24 were the key SAE genes.A competing endogenous RNA regulatory network was successfully constructed based on 9 lncRNAs, 28 mRNAs and 134 miRNAs in the hippocampus of mice with SAE. Conclusions:The results of RNA-seq find that 10 mRNAs including Ch25h, Il6ra, Lcn2, Sgk1, Nr4a3, Osm, Saa3, Ccl7, Sqle, Dhcr24 and lncRNAs such as Rian, Gm35874 and Gm34347 are key genes regulating SAE in mice. Meanwhile, a ceRNA regulatory network based on lncRNA-miRNA-mRNA is successfully constructed in the hippocampus of mice with SAE.
