This study aims to explore the mechanism through which Yishen Jiangtang Decoction(YSJTD) regulates endoplasmic reticulum stress(ERS)-mediated NOD-like receptor thermal protein domain associated protein 3(NLRP3) inflammasome to improve diabetic nephropathy(DN) in db/db mice. Thirty db/db mice were randomly divided into the model group, YSJTD group, ERS inhibitor 4-phenylbutyric acid(4-PBA) group, with 10 mice in each group. Additionally, 10 db/m mice were selected as the control group. The YSJTD group was orally administered YSJTD at a dose of 0.01 mL·g~(-1), the 4-PBA group was orally administered 4-PBA at a dose of 0.5 mg·g~(-1), and the control and model groups were given an equal volume of carboxylmethyl cellulose sodium. The treatments were administered once daily for 8 weeks. Food intake, water consumption, and body weight were recorded every 2 weeks. After the intervention, fasting blood glucose(FBG), glycosylated hemoglobin(HbA1c), urine microalbumin(U-mALB), 24-hour urine volume, serum creatinine(Scr), and blood urea nitrogen(BUN) were measured. Inflammatory markers interleukin-1β(IL-1β) and interleukin-18(IL-18) were detected using the enzyme-linked immunosorbent assay(ELISA). Renal pathology was assessed through hematoxylin-eosin(HE), periodic acid-Schiff(PAS), and Masson staining, and transmission electron microscopy(TEM). Western blot was used to detect the expression levels of glucose-regulated protein 78(GRP78), C/EBP homologous protein(CHOP), NLRP3, apoptosis-associated speck-like protein containing CARD(ASC), cysteinyl aspartate-specific proteinase(caspase-1), and gasdermin D(GSDMD) in kidney tissues. The results showed that compared to the control group, the model group exhibited poor general condition, increased weight and food and water intake, and significantly higher levels of FBG, HbA1c, U-mALB, kidney index, 24-hour urine volume, IL-1β, and IL-18. Compared to the model group, the YSJTD and 4-PBA groups showed improved general condition, increased body weight, decreased food intake, and lower levels of FBG, U-mALB, kidney index, 24-hour urine volume, and IL-1β. Specifically, the YSJTD group showed a significant reduction in IL-18 levels compared to the model group, while the 4-PBA group exhibited decreased water intake and HbA1c levels compared to the model group. Although there was a decreasing trend in water intake and HbA1c in the YSJTD group, the differences were not statistically significant. No significant differences were observed in BUN, Scr, and kidney weight among the groups. Renal pathology revealed that the model group exhibited more severe renal damage compared to the control group. Kidney sections from the model group showed diffuse mesangial proliferation in the glomeruli, tubular edema, tubular dilation, significant inflammatory cell infiltration in the interstitium, and increased glycogen staining and blue collagen deposition in the basement membrane. In contrast, the YSJTD and 4-PBA groups showed varying degrees of improvement in renal damage, glycogen staining, and collagen deposition, with the YSJTD group showing more significant improvements. TEM analysis indicated that the model group had extensive cytoplasmic edema, homogeneous thickening of the basement membrane, fewer foot processes, and widening of fused foot processes. In the YSJTD and 4-PBA groups, cytoplasmic swelling of renal tissues was reduced, the basement membrane remained intact and uniform, and foot process fusion improved.Western blot results indicated that compared to the control group, the model group showed upregulation of GRP78, CHOP, GSDMD, NLRP3, ASC, and caspase-1 expression. In contrast, both the YSJTD and 4-PBA groups showed downregulation of these markers compared to the model group. These findings suggest that YSJTD exerts a protective effect against DN by alleviating NLRP3 inflammasome activation through the inhibition of ERS, thereby improving the inflammatory response in db/db DN mice.

OBJECTIVES: To study the clinical characteristics, efficacy, and prognosis of pediatric Langerhans cell histiocytosis (LCH). METHODS: A retrospective analysis was conducted on 72 children with newly diagnosed LCH. RESULTS: The median age of the 72 children was 5 years (range: 0-14 years), with skull involvement being the most common (56 cases, 77.8%). The BRAF-V600E mutation was not associated with clinical characteristics, efficacy, or prognosis (P>0.05). The 5-year overall survival rate was 91.6%±4.2%, and the 5-year event-free survival (EFS) rate was 67.5%±5.8%. The 6-week chemotherapy response rate and 5-year EFS rate were lower in the risk organ involvement group compared to the no risk organ involvement group (P<0.05). The five-year overall survival rates for the group with multi-system involvement and the group with platelet count ≥450×10⁹/L were respectively lower than those for the single-system involvement group and the group with platelet count <450×10⁹/L (P<0.05). Risk organ involvement is an independent risk factor for 5-year EFS (P<0.05). CONCLUSIONS Skull is the most commonly affected site in pediatric LCH. The BRAF-V600E mutation is not related to clinical characteristics, efficacy, or prognosis. Elevated platelet count, risk organ involvement, and multisystem involvement are associated with poor prognosis, with risk organ involvement being an independent risk factor for 5-year EFS.

OBJECTIVE: To investigate the anti-tumor effects of cinobufacini (CINO) on hepatocellular carcinoma (HCC) induced by des-gamma-carboxy-prothrombin (DCP) and to uncover the underlying mechanisms. METHODS: The inhibitory effect of CINO on HCC cell proliferation was evaluated using the cell counting kit-8 method, and the apoptosis rate was quantified using flow cytometry. Immunofluorescence and Western blot analyses were used to investigate the differential expression of proteins associated with cell growth, apoptosis, migration, and invasion pathways after CINO treatment. The therapeutic potential of CINO for HCC was confirmed, and the possibility of combining cinobufacini with c-Met inhibitor for the treatment of primary HCC was further validated by in vivo experiments. RESULTS: Under the induction of DCP, CINO inhibited the activity of HCC cells, induced apoptosis, and inhibited migration and invasion. Upon the induction of DCP, CINO regulated c-Met activation and the activation of the phosphatidylinositol-3 kinase/protein kinase B (PI3K/AKT) and mitogen-activated protein kinase kinase/extracellular signal-regulated kinase (MEK/ERK) pathways. In a mouse model of HCC, CINO exhibited significant antitumor effects by inhibiting the phosphorylation of c-Met and the downstream PI3K/AKT and MEK/ERK pathways in tumor tissues. CONCLUSIONS CINO inhibited HCC cell growth, promoted apoptosis, and suppressed HCC cell invasion and migration by targeting c-Met and PI3K/AKT and MEK/ERK signaling pathways under DCP induction.

Objective To compare the role and importance of fibular fixation in tibiofibular fractures by Meta-analysis.Methods The literature related to the comparison of the efficacy of fixation of the fibula with or without fixation on the treatment of tibiofibular fractures was searched through the databases of China Knowledge Network,Wipu,Wanfang,The Cochrane Li-brary,Web of science and Pubmed,and statistical analysis was performed using RevMan 5.3 software.The rates of malrotation,rotational deformity,internal/external deformity,anterior/posterior deformity,non-union,infection,secondary surgery and op-erative time were compared between the fibula fixation and non-fixation groups.Results A total of 11 publications were includ-ed,six randomised controlled trials and five case-control trials,eight of which were of high quality.A total of 813 cases were in-cluded,of which 383 were treated with fibula fixation and 430 with unfixed fibulae.Meta-analysis results showed that fixation of the fibulae in the treatment of tibiofibular fractures reduced the rates of postoperative rotational deformity[RR=0.22,95％CI(0.10,0.45),P＜0.000 1]and internal/external deformity[RR=0.34,95％CI(0.14,0.84),P=0.02]and promoted fracture heal-ing[RR=0.76,95％CI(0.58,0.99),P=0.04].In contrast,the rates of poor reduction[RR=0.48,95％CI(0.10,2.33),P=0.36],anterior/posterior deformity[RR=1.50,95％CI(0.76,2.96),P=0.24],infection[RR=1.43,95％CI(0.76,2.72),P=0.27],sec-ondary surgery[RR=1.32,95％CI(0.82,2.11),P=0.25],and operative time[MD=10.21,95％CI(-17.79,38.21),P=0.47]were not statistically significant(P＞0.05)for comparison.Conclusion Simultaneous fixation of the tibia and fibula is clinically more effective in the treatment of tibiofibular fractures.

Objective To investigate the expression level and clinical application value of G-protein coupled receptor 15 ligand (GPR15L) in patients with systemic lupus erythematosus (SLE). Methods In a retrospective cohort, real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression levels of G-protein coupled receptor 15 (GPR15) mRNA and GPR15L mRNA in peripheral blood from 63 SLE patients (SLE group) and 57 healthy controls (control group). Enzyme-linked immunosorbent assay was employed to measure the serum GPR15L protein expression levels in the SLE group, control group, and 50 rheumatoid arthritis (RA) patients (disease control group). The relationship between serum GPR15L and laboratory indicators as well as therapeutic efficacy in SLE patients was analyzed. Receiver operating characteristic (ROC) curves were used to assess the diagnostic efficacy of serum GPR15 alone and combination with common autoantibody indicators for SLE. Multivariate Logistic regression analysis was conducted to explore the independent risk factors for SLE onset. Results Compared with the control group, the SLE group exhibited increased levels of GPR15 mRNA and GPR15L mRNA in peripheral blood (P=0.016 4, P < 0.000 1, respectively). The serum GPR15L expression in the SLE group was higher than that in the disease control group (P < 0.000 1). The serum GPR15L protein expression level in SLE patients was positively correlated with GPR15L mRNA and disease activity (r=0.301 3, P=0.016 4; r=0.361 7, P=0.003 6) and negatively correlated with complement C3 and C4 levels (r=-0.341 2, P=0.006 2; r=-0.338 4, P=0.006 7). The ROC curves showed that the area under the curve (AUC) for serum GPR15L in distinguishing the SLE group from the control group was 0.870 8, and the AUC for distinguishing the SLE group from the control group was 0.765 5. The diagnostic efficacy of serum GPR15L combined with anti-SSA for SLE was significantly improved, with an AUC of 0.895 2. Multivariate Logistic regression analysis revealed that elevated GPR15L protein and GPR15L mRNA were independent risk factors for SLE onset (P < 0.05). Conclusion The significant increase in serum GPR15L protein levels in SLE patients is closely related to SLE disease activity, and abnormal expression of GPR15L may play an important role in the pathogenesis of SLE.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective:To investigate the clinical significance of genetic and molecular changes in primary myeloid sarcoma(MS).Methods:Fourteen patients with primary MS were selected in Jiading District Central Hospital Affiliated Shanghai University of Medicine & Health Sciences,The First People's Hospital of Lianyungang from September 2010 to December 2021.AML1-ETO fusion,PML-RARα fusion and CBFβ breakage were detected by fluorescence in situ hybridization(FISH),and the mutations of NPM1,CEBPA,FLT3,RUNX1,ASXL1,KIT and TP53 genes were detected by new generation sequencing(NGS).Results:Among 14 patients,the MS occurred in bone,breast,epididymis,lung,chest wall,cervix,small intestine,ovary,lymph nodes and central nervous system.The tumor cells expressed MPO(13 cases),CD34(7 cases),CD43(8 cases),CD68(7 cases),CD99(8 cases)and CD117(6 cases).Cytogenetic abnormalities were observed in 4 cases,including 3 cases of AML1-ETO fusion and 1 case of CBF β breakage,while no PML-RAR α fusion was detected.There were no significant differences in overall survival(OS)and leukemia-free survival(LFS)between patients with and without AML1-ETO fusion/CBFβ breakage(both P＞0.05).Among the 14 patients,the number of NPM1,CEBPA,FLT3-ITD,RUNX1,ASXL1,KIT and TP53 gene mutations was 5,3,5,3,2,2,1.respectively,of which 7 cases had at least one mutation in FLT3-ITD,RUNX1,ASXL1 and TP53 gene.The OS and LFS of patients with FLT3-ITD,RUNX1,ASXL1 or TP53 mutation were shorter than those without mutations(both P＜0.01).Conclusion:The genetic and molecular abnormalities of primary MS can be detected by FISH and NGS techniques.FLT3-ITD,RUNX1,ASXL1 or TP53 mutation indicates a worse prognosis,but further clinical studies are needed to confirm it.

AIM To explore the clinical effects of enema of Cayratia japonica(Thunb.)Gagnep.on patients with distal ulcerative colitis.METHODS Sixty patients were randomly assigned into control group(30 cases)for 8-week intervention of Mesalazin Enteric-coated Tablets,and observation group(30 cases)for 8-week intervention of both enema of C.japonica and Mesalazin Enteric-coated Tablets.The changes in clinical effects,life quality scores,DAI score,Mayo activity index,intestinal mucosal barrier function indices(DAO,ET,D-lactic acid),intestinal flora(Bifidobacterium,Lactobacillus,Escherichia coli,Enterococcus),inflammatory factors(IL-10,IL-6,TNF-α)and safety indices were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the observation group displayed increased life quality scores,IL-10(P＜0.05),decreased DAI score,Mayo activity index,intestinal mucosal barrier function indices,IL-6,TNF-α(P＜0.05),enhanced Bifidobacterium,Lactobacillus(P＜0.05),and reduced Escherichia coli,Enterococcus(P＜0.05),which were more obvious than those in the control group(except for Enterococcus)(P＜0.05).No obvious adverse reactions were observable in the two groups.CONCLUSION For the patients with distal ulcerative colitis,enema of C.japonica can safely and effectively improve DAI score and Mayo activity index,which may contribute to the regulation of bacterial homeostasis,repairment of intestinal mucosal barrier and inhibition of inflammatory factor release.

Objective:To analyze the etiology of chronic spontaneous urticaria (CSU) in children and associated factors affecting the disease severity.Methods:A single-center cross-sectional study was conducted. Children aged ≤ 17 years with CSU were prospectively enrolled at the Department of Dermatology, Children′s Hospital of Chongqing Medical University from November 2021 to November 2022. Clinical data were collected, serum total IgE and allergen-specific IgE (sIgE) were detected, and basophil activation test (BAT) and autologous serum skin test (ASST) were performed. According to the ASST and BAT results, the children were divided into the chronic autoimmune urticaria (CAU) group (positive for both ASST and BAT), non-CAU group (negative for both ASST and BAT), and partial CAU group (positive for either ASST or BAT). Differences in the etiology and clinical characteristics were analyzed between the CAU group and the non-CAU group. Based on the weekly urticaria activity score (UAS7), the children with CSU were divided into the mild group (UAS7 < 16 points) and moderate to severe group (UAS7 ≥ 16 points). Factors associated with the severity of CSU in children were analyzed using logistic regression. Non-normally distributed quantitative data were expressed as M ( Q1, Q3), and the non-parametric rank sum test (Kruskal-Wallis test) was used to compare quantitative data among multiple groups. Results:This study enrolled a total of 93 children with CSU, including 50 males (53.8%) and 43 females (46.2%), with the age being 5.9 (2.9, 9.2) years, and the disease duration being 4 (2, 8) months; 32 patients (34.4%) were complicated by angioedema, 28 (30.1%) had a family history of chronic urticaria, 49 (52.7%) had a family history of atopic diseases, 14 (15.1%) had a family history of autoimmune diseases, and 26 (28.0%) had at least one atopic comorbidity. Etiologic analysis showed that 32 cases (32/69, 46.4%) were positive for ASST and 28 (28/70, 40.0%) were positive for BAT. Both ASST and BAT were performed in 57 cases, and they were divided into the CAU group (18 cases), non-CAU group (24 cases), and partial CAU group (15 cases) according to the test results. There were no significant differences in the age, disease duration, gender ratio, proportion of patients with atopic comorbidity, or proportion of patients having a family history of atopic diseases among the 3 groups (all P > 0.05), while the proportion of patients with moderate to severe CSU (UAS7 ≥ 16 points) was higher in the CAU group (16/18) than in the non-CAU group (11/24, P < 0.05). Triggering factors were identified in 19 cases (20.4%), including 18 (19.3%) cases of food allergy and 1 case (1.0%) of antibiotic allergy. The serum total IgE level was elevated in 22 cases (22/89, 24.7%), and 40 (40/81, 49.4%) showed elevated levels of at least 1 sIgE. The UAS7 of the children with CSU was 16 (15, 21) points, and there were 31 (33.3%) children with mild CSU and 62 (66.7%) with moderate to severe CSU. Univariate logistic regression analysis showed that BAT positivity was associated with disease severity ( OR = 7.566, 95% CI: 2.238 - 25.572, P < 0.05). After adjustment for age and gender, multivariate logistic regression analysis showed that BAT positivity was associated with moderate to severe CSU ( OR = 6.725, 95% CI: 1.361 - 33.227, P < 0.05) . Conclusions:Autoimmunity may be the main cause of CSU in children, followed by allergic factors. ASST could be used as a primary screening test for the diagnosis of CAU in children, and BAT may help identify CAU and predict disease severity.
