Objective To analyze the predictive value of the serum amyloid A/C-reactive protein ratio(SAA/CRP),lactate dehydrogenase(LDH),and chitinase-40(YKL-40)combined with conventional influencing factors for the prognosis of children with refractory mycoplasmal pneumonia(RMPP).Methods A retrospective study was conducted on 180 children with RMPP admitted to the First People's Hospital of Nanyang from January to December 2023,serving as study group,and 90 children with general mycoplasmal pneumonia(GMPP)as control group.The clinical data of the two groups,including age,gender,and serum levels of SAA/CRP,LDH,and YKL-40,were compared.On the day of admission,the disease severity of the children in study group was assessed and divided into mild(n=102)and severe(n=78)groups.After treatment,they were further categorized into poor prognosis(n=52)and good prognosis(n=128)groups based on the occurrence of adverse events.The levels of serum SAA/CRP,LDH,and YKL-40 were compared between mild-case and severe-case children in study group,as well as between children with good and poor prognosis.A binary logistic regression model was used to analyze the influencing factors for poor prognosis in children with RMPP.Receiver operating characteristic(ROC)curve was used to evaluate the predictive value of serum SAA/CRP,LDH,and YKL-40 for the prognosis of children with RMPP.Conventional influencing factors[disease severity,oxygen therapy duration,pneumonia severity index(PSI)score,and acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score]were used as the conventional prediction scheme,and the conventional prediction scheme combined with the levels of serum SAA/CRP,LDH,and YKL-40 was used as the new prediction scheme.The predictive values of the two prediction schemes for the prognosis of children with RMPP were compared.Results The levels of serum SAA/CRP,LDH,and YKL-40 in study group were higher than those in control group(P＜0.05),and the levels of serum SAA/CRP,LDH,and YKL-40 in children with severe RMPP were higher than those in children with mild RMPP(P＜0.05).In study group,the proportion of children with pleural effusion,the proportion of severe-case disease severity,oxygen therapy duration,PSI score,APACHE Ⅱ score,and the levels of serum SAA/CRP,LDH,and YKL-40 in children with poor prognosis were higher than those in children with good prognosis(P＜0.05).Binary logistic regression analysis showed that disease severity,oxygen therapy duration,PSI score,APACHE Ⅱ score,and the levels of serum SAA/CRP,LDH,and YKL-40 were all factors affecting poor prognosis in children with RMPP(P＜0.05).The areas under the curves(AUCs)of serum SAA/CRP,LDH,and YKL-40 for predicting the prognosis of children with RMPP were 0.756,0.749,and 0.734,respectively.The AUC of the new prediction scheme was 0.945,which was significantly higher than that of the conventional prediction scheme(AUC=0.859),with a statistically significant difference(P=0.011).Conclusion Serum SAA/CRP,LDH,and YKL-40 levels combined with the conventional prediction scheme have a high predictive efficacy for the prognosis of children with RMPP.

Objective To analyze the efficacy and safety of ustekinumab(UST)in patients with moderate-to-severe Crohn's disease(CD),and to identify factors influencing clinical outcomes.Methods Data were retrospectively collected from patients with moderate-to-severe CD treated with UST in the First Affiliated Hospital of Zhejiang Chinese Medical University and Hangzhou Hospital of Traditional Chinese Medicine between November 2020 and May 2023.Patients were categorized into first-line(not treated with biologic agents,n=68)and second-line(treated with biologic agents,n=66)treatment groups based on prior use of biologic agents.Baseline characteristics,including age,sex,smoking status,disease duration,age at diagnosis,lesion site,disease behavior,perianal disease,history of intestinal surgery,and CD-related drug use,were compared between the two groups.Crohn's disease activity indices(CDAI)were recorded at baseline,week 14,and week 52 to assess the clinical efficacy at weeks 14 and 52.Endoscopic evaluations were performed at baseline and week 52 to evaluate endoscopic efficacy at week 52.The 52-week drug persistence rate and safety profile were also analyzed.Influencing factors related to clinical outcomes were evaluated using univariate and multivariate logistic regression.Results A total of 134 patients with moderate-to-severe CD treated with UST were included.At week 14,clinical response and remission rates were 75.4%(101/134)and 33.6%(45/134),respectively,with no significant difference in clinical efficacy between first-line and second-line groups(clinical response rate:77.9%vs.72.7%,P=0.484;clinical remission rate:38.2%vs.28.8%,P=0.247).At week 52,clinical response and remission rates were 79.9%(107/134)and 56.0%(75/134),respectively.The rates of endoscopic response and remission were 70.9%(95/134)and 38.8%(52/134),respectively.There were no significant differences in clinical efficacy(clinical response rate:80.9%vs.78.8%,P=0.763;clinical remission rate:60.3%vs.51.5%,P=0.306)and endoscopic efficacy(endoscopic response rate:76.5%vs.65.2%,P=0.149;endoscopic remission rate:42.6%vs.34.8%,P=0.354)between the two groups.The 52-week drug persistence rate was 85.8%(115/134),and the adverse reaction rate was 4.5%(6/134).Compared with first-line treatment group,biologic-experienced patients had a significantly higher proportion of dose-optimized therapy in second-line treatment group(45.5%vs.22.1%,P=0.004).Multivariate logistic regression showed that the 14-week clinical response was a significant predictor of 52-week clinical remission,while perianal disease and intestinal surgery history were significant factors associated with treatment failure(P<0.05).Conclusions UST demonstrates significant efficacy in improving clinical and endoscopic outcomes for moderate-to-severe CD patients,with a favorable safety profile.Clinical response at 14 weeks is strongly predictive of clinical remission at 52 weeks.Patients with perianal disease or a history of intestinal surgery were at higher risk of treatment failure.

Background: Epimedii Folium, first recorded in the Shennong’s Classic of Materia Medica (Shen Nong Ben Cao Jing), is a traditional Chinese medicine (TCM) known for its effects of “benefiting Qi and strengthening the heart.” Icariside II (ICS II) is one of the main active components of Epimedii Folium, possessing cardiovascular protective and anti-inflammatory properties. However, the potential mechanisms of ICS II on myocardial ischemia (MI) remain unclear. Objective: The aim of the study was to investigate the effects and preliminary molecular mechanisms of ICS II in treating isoproterenolinduced MI in rats. Methods: A rat model of MI was established by subcutaneous injection of isoproterenol. Electrocardiography, echocardiography, myocardial enzymes analysis, heart weight index, triphenyltetrazolium chloride staining, histopathology, TUNEL staining, RT-qPCR, and Western blot were employed to evaluate the effects and preliminary molecular mechanisms of ICS II on MI rats. Results: Pharmacodynamic studies suggested that ICS II inhibited ST-segment elevation in electrocardiograms, improved cardiac function, reduced heart weight index and myocardial enzyme levels, decreased myocardial infarct size, alleviated cardiac histological damage, and inhibited apoptosis, thereby exerting cardioprotective effects in MI rats. Further studies revealed that ICS II may partially inhibit the expression of NLRP3/Caspase-1 axis-related targets at both protein and mRNA levels. Conclusions: Our findings indicate that ICS II exerts anti-MI effects, and its preliminary molecular mechanisms may be related to inhibiting the activation of the NLRP3/Caspase-1 axis to alleviate inflammatory responses.

Non-alcoholic fatty liver disease(NAFLD)is a metabolic disease characterized by abnormal deposition of lipid in hepatocytes.If not intervened in time,NAFLD may develop into liver fibrosis or liver cancer,and ultimately threatening life.NAFLD has complicated etiology and pathogenesis,and there are no effective therapeutic means and specific drugs.Currently,insulin sensitizers,lipid-lowering agents and hep-atoprotective agents are often used for clinical intervention,but these drugs have obvious side effects,and their effectiveness and safety need to be further confirmed.Adenosine monophosphate(AMP)-activated protein kinase(AMPK)plays a central role in maintaining energy homeostasis.Activated AMPK can enhance lipid degradation,alleviate insulin resistance(IR),suppress oxidative stress and inflammatory response,and regulate autophagy,thereby alleviating NAFLD.Natural herbal medicines have received extensive attention recently because of their regulatory effects on AMPK and low side effects.In this article,we reviewed the biologically active natural herbal medicines(such as natural herbal medicine formulas,extracts,polysaccharides,and monomers)that reported in recent years to treat NAFLD via regulating AMPK,which can serve as a foundation for subsequent development of candidate drugs for NAFLD.

Objective To investigate the role of p300 in lipid metabolism disorders.Methods Bioinformatics analysis was performed to analyze the expression patterns of p300 in lipid metabolism disorder-related diseases and its correlation with SREBP-1c and downstream lipid metabolic enzymes.Immunofluorescence assay was used to detect the expression of p300 in the liver tissues of the patients with varying disease severity of non-alcoholic fatty liver disease(NAFLD).A mouse model of lipid metabolism disorder was established in male C57BL/6J mice by feeding high-fat diet(HFD)for 12 weeks.Western blotting was employed to assess p300 expression level in the liver tissues of HFD-fed mice.A cell model of lipid metabolism disorder was established in HepG2/AML-12 cells induced with free fatty acid(FFA).The effects of siRNA-mediated knockdown of p300 was observed to measure the levels of intracellular total cholesterol(TC)and triglyceride(TG),lipid deposition,and production of reactive oxygen species(ROS).Results Clinically,p300 was highly expressed in lipid metabolism disorders,and its level was positively correlated with NAFLD severity(P<0.05).Gene Set Enrichment Analysis(GSEA)revealed that p300 expression was significantly associated with fatty acid metabolism,cholesterol homeostasis,lipogenesis,PPAR signaling pathway,and peroxisome pathway.In vivo,p300 was significantly up-regulated in the livers of HFD-fed mice(P<0.01).In vitro,FFA stimulation markedly increased p300 expression in both HepG2 and AML-12 cells(P<0.01),whereas p300 knockdown significantly reduced intracellular TG and TC levels(P<0.01),attenuated lipid droplet accumulation,and reversed FFA-induced ROS elevation(P<0.01).Furthermore,p300 expression was positively correlated with the expression of SREBP-1c and its downstream key lipid synthesis enzymes.Conclusion p300 may promote hepatic lipid accumulation by acetylating and activating SREBP-1c and regulating downstream lipid metabolic enzymes,thereby affecting lipid synthesis and oxidative stress.These findings suggest that p300 may be a potential therapeutic target for lipid metabolism disorder-related diseases.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

OBJECTIVE: High-altitude hypoxia exposure often damages hippocampus-dependent learning and memory. Nogo-A is an important axonal growth inhibitory factor. However, its function in high-altitude hypoxia and its mechanism of action remain unclear. METHODS: In an in vivo study, a low-pressure oxygen chamber was used to simulate high-altitude hypoxia, and genetic or pharmacological intervention was used to block the Nogo-A/NgR1 signaling pathway. Contextual fear conditioning and Morris water maze behavioral tests were used to assess learning and memory in rats, and synaptic damage in the hippocampus and changes in oxidative stress levels were observed. In vitro, SH-SY5Y cells were used to assess oxidative stress and mitochondrial function with or without Nogo-A knockdown in Oxygen Glucose-Deprivation/Reperfusion (OGD/R) models. RESULTS: Exposure to acute high-altitude hypoxia for 3 or 7 days impaired learning and memory in rats, triggered oxidative stress in the hippocampal tissue, and reduced the dendritic spine density of hippocampal neurons. Blocking the Nogo-A/NgR1 pathway ameliorated oxidative stress, synaptic damage, and the learning and memory impairment induced by high-altitude exposure. CONCLUSION: Our results demonstrate the detrimental role of Nogo-A protein in mediating learning and memory impairment under high-altitude hypoxia and suggest the potential of the Nogo-A/NgR1 signaling pathway as a crucial therapeutic target for alleviating learning and memory dysfunction induced by high-altitude exposure.

PURPOSE: To investigate the incidence and influencing factors of bone loss in patients with spinal cord injury (SCI). METHODS: A retrospective case-control study was conducted. Patients with SCI in our hospital from January 2019 to March 2023 were collected. According to the correlation between bone mineral density (BMD) at different sites, the patients were divided into the lumbar spine group and the hip joint group. According to the BMD value, the patients were divided into the normal bone mass group (t > -1.0 standard deviation) and the osteopenia group (t ≤ -1.0 standard deviation). The influencing factors accumulated as follows: gender, age, height, weight, cause of injury, injury segment, injury degree, time after injury, start time of rehabilitation, motor score, sensory score, spasticity, serum value of alkaline phosphatase, calcium, and phosphorus. The trend chart was drawn and the influencing factors were analyzed. SPSS 26.0 was used for statistical analysis. Correlation analysis was used to test the correlation between the BMD values of the lumbar spine and bilateral hips. Binary logistic regression analysis was used to explore the influencing factors of osteoporosis after SCI. p < 0.05 was considered statistically significant. RESULTS: The incidence of bone loss in patients with SCI was 66.3%. There was a low concordance between bone loss in the lumbar spine and the hip, and the hip was particularly susceptible to bone loss after SCI, with an upward trend in incidence (36% - 82%). In this study, patients with SCI were divided into the lumbar spine group (n = 100) and the hip group (n = 185) according to the BMD values of different sites. Then, the lumbar spine group was divided into the normal bone mass group (n = 53) and the osteopenia group (n = 47); the hip joint group was divided into the normal bone mass group (n = 83) and the osteopenia group (n = 102). Of these, lumbar bone loss after SCI is correlated with gender and weight (p = 0.032 and < 0.001, respectively), and hip bone loss is correlated with gender, height, weight, and time since injury (p < 0.001, p = 0.015, 0.009, and 0.012, respectively). CONCLUSIONS The incidence of bone loss after SCI was high, especially in the hip. The incidence and influencing factors of bone loss in the lumbar spine and hip were different. Patients with SCI who are male, low height, lightweight, and long time after injury were more likely to have bone loss.
