Sedentary bad habits and unhealthy diets in modern lifestyles have led to an upward trend in the incidence of obesity, and a series of diseases related to obesity have also gradually received attention. Multiple sclerosis is a chronic inflammatory disease of the central nervous system, and obesity has a common inflammatory component with most chronic diseases. Therefore, this paper reviews the research progress on the relationship between obesity and multiple sclerosis in order to better understand the role of obesity in the management of multiple sclerosis.

Objective To investigate the protective effect of recombinant Schistosoma japonicum cystatin(rSj-Cys)against acute liver injury induced by lipopolysaccharide(LPS)and D-GalN in mice.Methods Adult male C57BL/6J mice with or without LPS/D-GaIN-induced acute liver injury were given intraperitoneal injections of rSj-Cys or PBS 30 min after modeling(n=18),and serum and liver tissues samples were collected from 8 mice in each group 6 h after modeling.The survival of the remaining 10 mice in each group within 24 h was observed.Serum levels of ALT,AST,TNF-α and IL-6 of the mice were measured,and liver pathologies was observed with HE staining.The hepatic expressions of macrophage marker CD68,Bax,Bcl-2 and endoplasmic reticulum stress(ERS)-related proteins were detected using immunohistochemistry or immunoblotting,and TUNEL staining was used to detect hepatocyte apoptosis.Results The survival rates of PBS-and rSj-Cys-treated mouse models of acute liver injury were 30%and 80%at 12 h and were 10%and 60%at 24 h after modeling,respectively;no death occurred in the two control groups within 24 h.The mouse models showed significantly increased serum levels of AST,ALT,IL-6 and TNF-α and serious liver pathologies with increased hepatic expressions of CD68 and Bax,lowered expression of Bcl-2,increased hepatocyte apoptosis,and up-regulated expressions of ERS-related signaling pathway proteins GRP78,CHOP and NF-κB p-p65.Treatment of the mouse models significantly lowered the levels of AST,ALT,IL-6 and TNF-α,alleviated liver pathologies,reduced hepatic expressions of CD68,Bax,GRP78,CHOP and NF-κB p-p65,and enhanced the expression of Bcl-2.In the normal control mice,rSj-Cys injection did not produce any significant changes in these parameters compared with PBS.Conclusion rSj-Cys alleviates LPS/D-GalN-induced acute liver injury in mice by suppressing ERS,attenuating inflammation and inhibiting hepatocyte apoptosis.

Traditional medications used for treating autoimmune diseases often come with a wide range of adverse effects. Current treatments focus mainly on symptom management, resulting in significant health issues and financial burdens for patients. Recently, clinical research has demonstrated the potential of helminths and their derivatives as effective therapies for autoimmune disorders. Helminths, being a near-natural immunomodulator, exhibit milder effects than broad-spectrum immunosuppressants and corticosteroids, thereby presenting a promising alternative for the treatment of autoimmune diseases. However, different helminths' therapeutic efficacy and mechanisms and their derivatives in treating autoimmune diseases may vary. Therefore, we aim to review recent clinical advancements in the use of helminths and their derivatives for treating inflammatory bowel disease, multiple sclerosis, and autism spectrum disorder, with a view to offering novel clinical treatment approaches.

Objective:To analyze the effects of microvascular invasion (MVI) and anatomical hepatectomy on early recurrence and survival of patients with hepatocellular carcinoma (HCC).Methods:The data of 246 patients with HCC admitted to 215 Hospital of Shaanxi Nuclear Industry, Chinese PLA General Hospital and Beijing Tsinghua Chang Gung Hospital from July 2008 to June 2019 were retrospectively analyzed, including 208 males and 38 females, aged (53.8±9.6) years. According to the occurrence of MVI, 246 patients were divided into the MVI group ( n=83) and control group ( n=163, without MVI). Hepatitis B virus (HBV) infection, preoperative alpha-fetoprotein (AFP), maximum tumor diameter, intraoperative blood loss were compared between the two groups. The recurrence-free survival and cumulative survival were compared between the two groups before and after the inverse probability weighted correction for propensity score. Results:The propensity score was calculated by logistic regression model. After inverse probability weighted correction, the virtual sample size was 247 cases (82 cases in MVI group and 165 cases in control group). The proportion of HBV infection, with a serum level of AFP > 200 μg/L, the maximum diameter of tumor and the intraoperative blood loss were higher in MVI group (all P<0.05). The risk of early recurrence in patients undergoing anatomical hepatectomy ( n=107) was lower than that in patients undergoing non-anatomical hepatectomy ( n=139) (univariate Cox regression analysis of HR=1.60, 95% CI: 1.06 to 2.42, P=0.020), but the overall survival was comparable (univariate Cox regression analysis of HR=1.66, 95% CI: 0.80 to 3.42, P=0.200). The recurrence-free survival (RFS) of MVI group was lower than that of the control group, and the postoperative cumulative survival rate was also lower before the inverse probability weighted correction of the tendency score. The RFS in MVI group was lower than that in control group after the tendency score was adjusted by inverse probability weighting ( HR=2.62, 95% CI: 1.61 to 4.27, P<0.001). There was no significant difference in the cumulative survival between the MVI and control group ( HR=2.09, 95% CI: 0.89 to 4.93, P=0.050). Conclusion:MVI is associated with early postoperative recurrence in patients with HCC, and the early recurrence rate after anatomical hepatectomy is lower than that after non-anatomical hepatectomy.

Objective:To summarize the experience of the precise prevention and control strategy of novel coronavirus infection in the pediatric intensive care unit(PICU)during the epidemic of the Omicron variant.Methods:A retrospective analysis was performed on the strategies and management experience of precise prevention and control of novel coronavirus infection in PICU at Pediatric Hospital of Fudan University from March 1 to May 10, 2022.Results:According to the national and Shanghai novel coronavirus infection prevention and control standards, the PICU in our hospital, in accordance with the specialty characteristics of PICU, cooperated with the hospital′s department of infection and medical department to jointly construct a precise ward management strategy for the outbreak of the omicron mutants infection.Precise prevention and control management strategies were formulated from four aspects: the admission process of critically ill children, the division of PICU ward areas and nosocomial infection protection, the reception management system for children′s family members, and the " bubble management" system for PICU staff, and run them for 3 months.During the epidemic, there was no nosocomial infection of novel coronavirus infection in children or medical staff.During the period, a total of 140 critically ill children were admitted, including 87 cases transferred from the general ward in the hospital, 48 cases from the emergency department(non-febrile, 3 cases transferred by the transfer team), four cases from fever clinic, and one case from control ward.Four of the critically ill children had no emergency nucleic acid test report when they were admitted to the PICU.Among the 140 critically ill children, 54 patients received mechanical ventilation, 18 patients received blood purification, and two patients were monitored after liver transplantation.Seventy-eight (55.7%) children had underlying diseases.Conclusion:During the current round of novel coronavirus epidemic in Shanghai, PICU in our hospital formulated the admission and ward management procedures for critically ill children, which ensured the prevention and control of nosocomial infection of novel coronavirus, and at the same time ensured the treatment of critically ill children to the greatest extent.

Methods: The young and middle-aged patients with T2DM from September 2019 to September 2020 in Hangzhou First People's Hospital, affiliated to the Medical School of Zhejiang University, were selected as the subjects, the general information questionnaire, Perceived Social Support Scale ( PSSS ) , Conner-Davidson Resilience Scale ( CD-RISC ), Diabetes Distress Scale (DDS) and Diabetes Management Self-efficacy Scale ( DMSES ) were used to investigate, the multivariate linear regression model was used to analyze the influencing factors for resilience in young and middle-aged patients with T2DM. Results: A total of 250 questionnaires were distributed and 238 valid questionnaires were recovered. The effective recovery rate was 95.20%. Among 238 patients, 142 cases ( 59.66% ) were males and 96 cases ( 40.34% ) were females; 168 cases ( 70.59% ) were 45-59 years old. The CD-RISC score was 70.49±12.81, PSSS score was 63.70±10.90, DDS score was 2.14±0.87, and DMSES score was 130.22±38.49. The results of multivariate regression analysis indicated that educational level, average monthly family income, fasting blood glucose, self-efficacy, social support and diabetes distress were the influencing factors for resilience of young and middle-aged patients with T2DM ( P<0.05 ). Conclusion The level of mental resilience in young and middle-aged patients with T2DM is mainly related to the level of education, monthly family income, blood glucose control, diabetes distress, self-efficacy and social support.

Objective To compare the clinical effects of interscalene brachial plexus block and superior trunk block in arthroscopic shoulder surgery with 0.25% ropivacaine. Methods 46 patients undergoing shoulder arthroscopy surgery were included and randomly divided into group ISB (n=23) and group ST (n=23). Patients in group ISB received 10 ml 0.25% ropivacaine on the lateral side of C5 and C6. Patients in group ST were treated with 5 ml 0.25% ropivacaine on both sides of the superior trunk of brachial plexus. The diaphragmatic excursion, Numerical Rating Scale(NRS), duration of the block, handgrip strength were recorded at different time. Results No statistical difference was detected between the two groups in the reduction of diaphragmatic excursion within 30 min after block (P>0.05). Compared with ISB patients, ST patients had significantly less diaphragmatic excursion at 3 h after block（P<0.05). 30 minutes after block, 8.7% patients in ISB group reached complete HDP and 52.2% patients reached partial HDP. At the same time, no complete HDP and 26.1% partial HDP were detected in ST group. 3 hours after block, patients in ST group had lower complete HDP rate (0.0% vs 17.4%) and lower partial HDP rate (39.1% vs 65.2%) than patients in ISB group. At 30 minutes and 3 h after block, the reduction of grip strength in ST group was significantly lower than that in ISB group (P<0.001). ST group had lower NRS than ISB group (P<0.05). The average block time in ISB group (8.3±1.97 )h was significantly lower than that in ST group (10.9±1.26)h (P<0.01). Conclusion Superior trunk block with 10 ml 0.25% ropivacaine is superior compared to interscalene brachial plexus block in occurrence of HDP, decrease of grip strength, postoperative pain and block duration.
