Excessive and persistent inflammatory responses are a potential pathological condition that can lead to diseases of various systems, including nervous, respiratory, digestive, circulatory, and endocrine systems. Cannabinoid type 2 receptor(CB2R) belongs to the G protein-coupled receptor family and is widely distributed in immune cells, peripheral tissues, and the central nervous system. It plays a role in inflammatory responses under various pathological conditions. The down-regulation of CB2R activity is an important marker of inflammation and and CB2R modulators have been shown to have anti-inflammatory effects. This study explored the relationship between CB2R and inflammatory responses, delved into its regulatory mechanisms in inflammatory diseases, and summarized the research progress on CB2R modulators from plants other than cannabis, including plant extracts and monomeric compounds, in exerting anti-inflammatory effects. The aim is to provide new insights into the prevention and treatment of inflammatory diseases.

OBJECTIVES: To investigate the preadmission follow-up condition of neonates hospitalized due to severe hyperbilirubinemia after discharge from the department of obstetrics and the influencing factors for follow-up compliance. METHODS: A multicenter retrospective case-control study was performed for the cases from the multicenter clinical database of 12 units in the Quality Improvement Clinical Research Cooperative Group of Neonatal Severe Hyperbilirubinemia in Jiangsu Province of China from January 2019 to April 2021. According to whether the follow-up of neonatal jaundice was conducted on time after discharge from the department of obstetrics, the neonates were divided into two groups: good follow-up compliance and poor follow-up compliance. The multivariate logistic regression model was used to identify the influencing factors for follow-up compliance of the neonates before admission. RESULTS: A total of 545 neonates with severe hyperbilirubinemia were included in the study, with 156 neonates (28.6%) in the good follow-up compliance group and 389 (71.4%) in the poor follow-up compliance group. The multivariate logistic regression analysis showed that low gestational age at birth, ≥10% reduction in body weight on admission compared with birth weight, history of phototherapy of siblings, history of exchange transfusion of siblings, Rh(-) blood type of the mother, a higher educational level of the mother, the use of WeChat official account by medical staff to remind of follow-up before discharge from the department of obstetrics, and the method of telephone notification to remind of follow-up after discharge were associated with the increase in follow-up compliance (P<0.05). CONCLUSIONS Poor follow-up compliance is observed for the neonates with severe hyperbilirubinemia after discharge from the department of obstetrics, which suggests that it is necessary to further strengthen the education of jaundice to parents before discharge and improve the awareness of jaundice follow-up. It is recommended to remind parents to follow up on time by phone or WeChat official account.

OBJECTIVE: To evaluate the effect of photobiomodulation (PBM) on the drainage of brain interstitial fluid (ISF) and to investigate the possible mechanism of the positive effect of PBM on Alzheimer's disease (AD). METHODS: Twenty-four SD male rats were randomly divided into PBM group (n=12), sham PBM group (n=6), and negative control group (n=6). According to the injection site of tracer, the PBM group was further divided into PBM-ipsilateral traced group (n=6) and PBM-contralateral traced group (n=6). Rats in the PBM group and the sham PBM group were exposed to the dura minimally invasively on the skull corresponding to the frontal cortical area reached by ISF drainage from caudate nucleus region. The PBM group was irradiated by using 630 nm red light (5-6 mW/cm²), following an irradiation of 5 min with a 2 min pause, and a total of 5 times; the sham PBM group was kept in the same position for the same time using the light without power. The negative control group was kept without any measure. After PBM, tracer was injected into caudate nucleus of each group. The changes of ISF drainage in caudate nucleus were observed according to the diffusion and distribution of tracer molecule by tracer-based magnetic resonance imaging, and the structural changes of brain extracellular space (ECS) were analyzed by diffusion rate in ECS-mapping (D_ECS-mapping) technique. Finally, parameters reflecting the structure of brain ECS and the drainage of ISF were obtained: volume fraction (α), tortuo-sity (λ), half-life (T_1/2), and D_ECS. The differences of parameters among different groups were compared to analyze the effect of PBM on brain ECS and ISF. One-Way ANOVA post hoc tests and independent sample t test were used for statistical analysis. RESULTS: The parameters including T_1/2, D_ECS, and λ were significantly different among the PBM-ipsilateral traced group, the PBM-contralateral traced group, and the sham PBM group (F=79.286, P < 0.001; F=13.458, P < 0.001; F=10.948, P=0.001), while there was no difference in the parameter α of brain ECS among the three groups (F=1.217, P=0.324). Compared with the sham PBM group and the PBM-contralateral traced group, the PBM-ipsilateral traced group had a significant decrease in the parameter T_1/2 [(45.45±6.76) min vs. (76.01±3.44) min, P < 0.001; (45.45±6.76) min vs. (78.07±4.27) min, P < 0.001], representing a significant acceleration of ISF drainage; the PBM-ipsilateral traced group had a significant increase in the parameter D_ECS [(4.51±0.77)×10^-4 mm²/s vs. (3.15±0.44)×10^-4 mm²/s, P < 0.001; (4.51±0.77)×10^-4 mm²/s vs. (3.01±0.38)×10^-4 mm²/s, P < 0.001], representing a significantly increased molecular diffusion rate of in the brain ECS; the PBM-ipsilateral traced group had a significant decrease in the parameter λ (1.51±0.21 vs. 1.85±0.12, P=0.001; 1.51±0.21 vs. 1.89±0.11, P=0.001), representing a significant decrease in the degree of tortuosity in the brain ECS. CONCLUSION PBM can regulate the brain ISF drainage actively, which may be one of the potential mechanisms of the effect of PBM therapy on AD. This study provides a new method for enhancing the brain function via ECS pathway.

OBJECTIVE: To explore the mechanism of catgut embedding at back- points on nonalcoholic steatohepatitis (NASH) in rats based on IKK/IKB/NF-κB signaling pathway and downstream inflammatory factors. METHODS: Eighty SPF SD rats were selected, among them 10 rats were selected divided into a normal group (group A), and the remaining 70 rats were fed with high-fat diet to establish NASH model. At the end of 12 weeks, 10 rats were randomly selected to verify whether the model establishment was successful. Then the remaining 60 rats were randomly divided into a model group (group B), a catgut embedding at back- points group (group C), a catgut embedding at abdominal points group (group D), an acupuncture at back- points group (group E), a sham catgut embedding group (group F) and a western medication group (group G), 10 rats in each group. The rats in the group C were treated with catgut embedding at "Ganshu" (BL 18), "Pishu" (BL 20), "Weishu" (BL 21) and "Shenshu" (BL 23); the rats in the group D were treated with catgut embedding at "Daheng" (SP 15), "Fujie" (SP 14), "Huaroumen" (ST 24) and "Tianshu" (ST 25); the rats in the group E were treated with acupuncture at the same acupoints as the group C; the rats in the group F were treated with catgut embedding at back- points but the needle did not enter subcutaneous tissue gamma; the rats in the group G were treated with intragastric administration of vitamin E capsule. All the treatment was given for 4 weeks. The rats in the group A were fed with normal diet until the end of 16 weeks without any intervention. The rats in the group B continued to be fed with high-fat diet until the end of 16 weeks. After the intervention, the liver index was calculated; the liver histomorphology was observed by HE staining; the liver function [alanine aminotransferase (ALT), gamma glutamyl transferase (γ-GGT), alkaline phosphatase (ALP)] and blood lipid [serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL)] were measured by serum biochemistry. The serum levels of TNF-α, IL-6 and IL-1βwere detected by ELISA, and the expressions of IKK-α, NF-κBp65, IL-6, IL-1β and TNF-α proteins in liver tissue were detected by Western blot. The temperature of the conception vessel and the governor vessel was measured by infrared thermography. RESULTS: Compared with the group A, the obvious steatosis and inflammatory cell infiltration were observed in the group B, and the body weight, liver wet-weight and liver index were all increased (<0.01). Compared with the group B, the liver tissue morphology in the group C, the group D, the group E and the group G was improved in varying degrees, and the liver index was decreased (<0.05), which was the most significant in the group C (<0.05). Compared with the group A, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β were all increased in the group B (<0.01); compared with the group B, the ALT, γ-GGT, ALP, TG, TC, LDL, TNF-α, IL-6 and IL-1β in all intervention groups were all decreased in varying degrees (<0.01, <0.05), which was the most significant in the group C (<0.01). Compare with the group A, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in the group B were all increased (<0.01); compared with the group B, the expressions of IKK-α, NF-κBp65, TNF-α, IL-6 and IL-1βproteins in all intervention groups were decreased in varying degrees (<0.05), which was the most significant in the group C (<0.01). Compared with the group A, the temperature of the conception vessel and governor vessel was decreased in the group B (<0.01). Compared with the group B, the temperature of the conception vessel and governor vessel was all increased in the group C, the group D and the group E (<0.01); the temperature of the conception vessel in the group C was similar to that in the group D (>0.05), while the temperature of the governor vessel in the group C was superior to that in the group D (<0.05). CONCLUSION The catgut embedding at back- points might inhibit the activation of IKK/IKB/NF-κB signaling pathway to interrupt the inflammatory cascade, and reduce the "second hit" of inflammatory factors on liver, which could slow down NASH progress and prevent and treat NASH.

Objective:To investigate the risk factors of dysplasia in patients with ulcerative colitis (UC) in China.Methods:From March 1st, 2012 to December 30th, 2013, a total of 154 UC patients were prospectively enrolled from the following 11 hospitals, Xijing Hospital of Digestive Diseases, Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Peking Union Medical College Hospital, Renji Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Nanfang Hospital affiliated to Southern Medical University, China-Japan Friendship Hospital, The Second Hospital of Hebei Medical University, West China Hospital affiliated to Sichuan University, The Seventh Medical Center of PLA General Hospital, Zhongshan Hospital affiliated to Xiamen University, and the First Affiliated Hospital of Anhui Medical University. The patients were followed up till December 1st, 2017. All the UC patients underwent colon endoscopy and histopathological evaluation. T test and Chi-square test were used for statistical analysis. Cox proportional risk model was used for identifying the risk factors of dysplasia in UC patients. Results:Finally, 133 UC patients were enrolled, the age was (50.0±11.9) years, the diagnosis age was (35.5±11.6) years, the course of disease was (14.5±6.7) years, and the number of endoscopic examinations was (3.4±1.6) times. A total of 21 patients were detected with dysplasia. No patients were detected with colorectal cancer. The results of univariate analysis revealed that the diagnosis age (hazard ratio ( HR)=1.05, 95% confidence interval ( CI) 1.01 to 1.10, P=0.009) and extensive colitis ( HR=2.92, 95% CI 0.97 to 8.79, P=0.057) were factors with statistically significant difference. The results of multivariate analysis revealed that the old age at diagnosis ( HR=1.06, 95% CI 1.02 to 1.11, P=0.003) and extensive colitis ( HR=3.68, 95% CI 1.21 to 11.19, P=0.022) were independent risk factors of dysplasia in UC patients. The cumulative incidence of dysplasia of UC patients with extensive colitis was higher than that of patients with left-sided colitis (24.3%, 17/70 vs. 6.3%, 4/63), and the difference was statistically significant ( χ2=8.023, P=0.005). Conclusions:Extensive colitis and older age at diagnosis are two independent risk factors of dysplasia in UC patients of our country. The cancer monitoring should be strengthened in UC patients with long course of disease and extensive colitis.
