Aim To investigate the role of triggering receptor expressed on myeloidcells 2(TREM2)in syn-aptic plasticity induced by cocaine addiction.Methods C57BL/6J mice and Trem2 knockout mice were uti-lized in this study to evaluate the alterations in postsyn-aptic density protein 95(PSD-95)and synapsin 1(SYN1)within the cortex and hippocampus of co-caine-addicted mice by using immunological tech-niques.Results HE staining and Nissl staining showed increased neuronal damage in the hippocampus and cortex of mice after cocaine addiction.The results of immunohistochemistry and fluorescence of PSD-95 and SYN1 were consistent with the expression trend of Western blot.In the wild type mouse model,the ex-pression level of PSD-95 in the hippocampus and cortex was lower than that in the saline group,and the ex-pression of SYN1 was higher than that in the saline group.In the knockout mouse model,the expression levels of PSD-95 and SYN1 in the hippocampus and cortex were significantly higher than those in the saline group after cocaine addiction.The expression levels of PSD-95 and SYN1 in the hippocampus and cortex of cocaine knockout mice were higher than those of co-caine wild type mice.Conclusion Cocaine addiction can change the synaptic plasticity,and TREM2 plays a regulatory role in the synaptic plasticity of hippocampus and cortex in mice with cocaine injury.TREM2 is ex-pected to be a new target for studying the mechanism of cocaine addiction.

Objective To analyze the changes of neutrophil-to-albumin ratio(NPAR),monocyte-to-lymphocyte ratio(MLR),neutrophil-to-lymphocyte ratio(NLR)and interleukin-17A(IL-17A)in patients with severe autoimmune encephalitis(AE)and the predictive value of their combined detection for prognosis.Methods A total of 105 patients with severe AE admitted from May 2021 to April 2025 were selected as the severe group.During the same period,35 patients with mild-to-moderate AE and 35 healthy controls were enrolled in a 3:1:1 ratio as the mild-to-moderate group and control group respectively.The levels of NPAR,MLR,NLR and IL-17A were compared among the three groups.Patients with severe AE were observed for one month.According to the prognosis of patients,they were divided into poor prognosis subgroup[modified Rankin scale(mRS)score≥3,n=31]and good prognosis subgroup(mRS score<3,n=74).The levels of NPAR,MLR,NLR and IL-17A in the two groups were compared,to analyze the correlation between NPAR,MLR,NLR and IL-17A levels and mRS score in patients with severe AE,and to evaluate the predictive value of combined detection of the four indicators for prognosis in these patients.Results The levels of NPAR,MLR,NLR and serum IL-17A in mild-to-moderate group and severe group were higher than those in control group,which were higher in the severe group than in the mild-to-moderate group(P<0.05).The course of disease in the poor prognosis group was longer than that in the good prognosis group,and the proportion of patients with γ-aminobutyric acid B receptor antibody and the levels of NPAR,MLR,NLR and serum IL-17A were higher than those in the good prognosis group(P<0.05).Higher levels of NPAR,MLR,NLR and serum IL-17A were all risk factors for poor prognosis of patients with severe AE(OR=2.445,4.319,2.502,1.791,P<0.05).The levels of NPAR,MLR,NLR and serum IL-17A were positively correlated with the mRS score of patients with severe AE(r=0.546,0.519,0.554,0.561,P<0.001).The area under the receiver operating characteristic(ROC)curve(AUC)of NPAR,MLR,NLR and IL-17A detected in combination in predicting the prognosis of patients with severe AE was higher than that of the four indicators detected alone(P<0.05).Conclusion The changes in NPAR,MLR,NLR and IL-17A levels in patients with AE were closely related to the severity and prognosis of the disease.In the meantime,higher levels of NPAR,MLR,NLR and serum IL-17A were risk factors for poor prognosis,and the combined detection of the four indicators could effectively improve the predictive value for prognosis in patients with severe AE.

OBJECTIVE: To evaluate the efficacy and safety of Wuda Granule (WDG) on recovery of gastrointestinal function after laparoscopic bowel resection in the setting of enhanced recovery after surgery (ERAS)-based perioperative care. METHODS: A total of 108 patients aged 18 years or older undergoing laparoscopic bowel resection with a surgical duration of 2 to 4.5 h were randomly assigned (1:1) to receive either WDG or placebo (10 g/bag) twice a day from postoperative days 1-3, combining with ERAS-based perioperative care. The primary outcome was time to first defecation. Secondary outcomes were time to first flatus, time to first tolerance of liquid or semi-liquid food, gastrointestinal-related symptoms and length of stay. Subgroup analysis of the primary outcome according to sex, age, tumor site, surgical time, histories of underlying disease or history of abdominal surgery was undertaken. Adverse events were observed and recorded. RESULTS: A total of 107 patients [53 in the WDG group and 54 in the placebo group; 61.7 ± 12.1 years; 50 males (46.7%)] were included in the intention-to-treat analysis. The patients in the WDG group had a significantly shorter time to first defecation and flatus [between-group difference -11.01 h (95% CI -20.75 to -1.28 h), P=0.012 for defecation; -5.41 h (-11.10 to 0.27 h), P=0.040 for flatus] than the placebo group. Moreover, the extent of improvement in postoperative gastrointestinal-related symptoms in the WDG group was significantly better than that in the placebo group (P<0.05). Subgroup analyses revealed that the benefits of WDG were significantly superior in patients who were male, or under 60 years old, or surgical time less than 3 h, or having no history of basic disease or no history of abdominal surgery. There were no serious adverse events. CONCLUSION The addition of WDG to an ERAS postoperative care may be a viable strategy to enhance gastrointestinal function recovery after laparoscopic bowel resection surgery.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

OBJECTIVE: To evaluate the efficacy and safety of Pai-Neng-Da Capsule (, panaxadiol saponins component, PNDC) in combination with the cyclosporine and androgen for patients with chronic aplastic anemia (CAA). METHODS: A total of 79 CAA patients was randomly divided into 2 groups by a random number table, including PCA group [43 cases, orally PNDC 320 mg/d plus cyclosporine 5 mg/(kg·d) plus andriol 80 mg/d] and CA group [36 cases, orally cyclosporine 5 mg/(kg·d) plus andriol 160 mg/d]. All patients were treated and followed-up for 6 treatment courses over 24 weeks. The complete blood counts, score of Chinese medical (CM) symptoms were assessed and urine routine, electrocardiogram, hepatic and renal function were observed for safety evaluation. Female masculinization rating scale was established according to the actual clinical manifestations to evaluate the accurate degree of masculinization in female CAA patients treated by andriol. RESULTS: The effective rates were 88.1% (37/42) in the PCA group and 77.8% (28/36) in the CA group based on the standard for the therapeutic efficacy evaluation of hematopathy. There was no significant difference in the white blood cell (WBC) counts, platelet counts and hemoglobin concentration of peripheral blood between two groups after 6 months treatment. The masculinization score of female patient in the PCA group was significantly lower than the CA group (P<0.05). The mild abdominal distention was observed in 1 cases in the PCA group. In CA group, the abnormalities in the hepatic function developed in 2 cases and the renal disfunction was found in 1 case. CONCLUSION The PNDC possesses certain curative effects in the treatment of CAA without obvious side-effects and can partially replace andriol thereby to reduce the degree of masculinization [Registried at Chinese Clinical Trial Registry (ChicTR1900028153)].

Objective:To investigate the incidence, clinical characteristics and risk factors of growth retardation in pediatric onset IBD patients.Methods:A cross-sectional study was conducted. IBD patients with the age at diagnosis younger than 18 years old were recruited and screened in the Wechat group of patients in 8 IBD medical centers across the country. Demographic, clinical and growth-related data were collected through questionnaire survey, and the incidences of growth retardation at the time of diagnosis and investigation were calculated. According to whether there was growth retardation at the time of investigation, the patients were divided into growth retardation group and non-growth retardation group. The influencing factors of growth retardation were analyzed by the univariate analysis and multivariate Logistic regression analysis.Results:A total of 97 patients were involved including 8 ulcerative colitis (UC) and 89 Crohn′s disease (CD). There was no growth retardation in UC patients. Among 89 patients with CD, there were 48 males and 41 females, and the age was 15.5 (1.0, 21.0) years old. At the time of investigation, 14 patients (15.7%) with growth retardation were set as the growth retardation group, and 75 without growth retardation were set as the non-growth retardation group. The incidence of growth retardation was 19.0% (16/84) at the time of diagnosis. Univariate analysis results showed that compared with non-growth retardation group, patients in growth retardation group had lower diagnostic age [5.0 (1.0, 13.8) years old vs. 14.0 (12.0, 16.0) years old, P = 0.003], severer disease activity ( P = 0.006), higher proportion of acute gastrointestinal perforation [28.6% (4/14) vs. 2.7% (2/75), P = 0.005], higher proportion of patients in using glucocorticoids [64.3% (9/14) vs. 33.3% (25/75), P = 0.029), and longer time of using glucocorticoids [1.5 (0, 6.5) months vs. 0 (0, 3.0) months, P = 0.040], while the proportion of patients using biological agents was lower [42.9% (6/14) vs. 80.0% (60/75), P = 0.010], and the time of using biological agents was shorter [0 (0, 6.3) months vs. 7.0 (1.0, 12.0) months, P = 0.006]. Logistic regression analysis revealed that the age at diagnosis of CD was still a risk factor for growth retardation after correcting other factors ( OR = 6.909, 95% CI: 1.250-38.195, P = 0.027) . Conclusion:The pediatric onset IBD patients with low diagnostic age are prone to growth retardation, which should be paid attention to.

The differences of the active ingredients in Dendrobium huoshanense of different growth years and their protective effects on acute liver injury were studied to provide evidence for optimizing harvest time. The contents of polysaccharides, total flavonoids and total alkaloids in D. huoshanense of different growth years were determined by UV spectrophotometry, and the contents of gigantol in D. huoshanense were determined by HPLC. C57 BL/6 mice were randomly divided into blank control group(saline), modeling group(saline), high-dose(7.5 g·kg~(-1)) and low-dose(1.25 g·kg~(-1)) groups of D. huoshanense of different growth years. Each group was intragastrically administered every day for 2 weeks. 500 mg·kg~(-1) paracetamol was injected intraperitoneally 2 h after last treatment except the control group. After 12 hours, the serum and liver tissues were collected to detect the activities of ALT and AST, and the levels of SOD and MDA. The hepatic histopathological examination was performed. The results showed that the chemical constituents of D. huo-shanense of different growth years were significantly different(P<0.05). The contents of polysaccharide and gigantol of D. huoshanense of 2 growth years were the highest. The contents of flavonoids and alkaloids of D. huoshanense of 3 growth years were the hig-hest, followed by the D. huoshanense of 2 growth years, and the lowest were that of 1 growth year. Compared with the modeling group, D. huoshanense of different growth years could decrease the activities of ALT and AST in serum. Meanwhile, the levels of MDA reduced significantly, while those of SOD increased markedly. Histopathological results suggested that all D. huoshanense samples were effective in the reduction of the necrosis of hepatocytes in different degrees. The results of the multi-component SPSS paired tests showed that polysaccharide and gigantol probably played a leading role in the liver protection effects, while D. huoshanense of 2 growth years showed the best efficacy. The optimal harvesting time of D. huoshanense is 2 growth years.
