Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

Abstract On September 26, 2024, a municipal hospital in Jiaxing City reported a maternal case of Listeria monocytogenes infection. In order to clarify the source of infection, the Jiaxing Center for Disease Control and Prevention immediately conducted the epidemiological investigation, laboratory testing and related disposal work. The case presented with fever (37.9 ℃), gradually intensifying paroxysmal abdominal pain without obvious cause, and went to hospital on the day of onset. Due to fetal intrauterine distress, a male infant was delivered by cesarean section on the same day. The epidemiological investigation identified that the case usually consumed fruits, often store fruits such as watermelon and grapes in the refrigerator alongside raw meat, and the refrigerator had never been cleaned or disinfected, posing a risk of cross contamination. Laboratory tests on amniotic fluid sample from the pregnant woman, infant blood sample showed positive results for Listeria monocytogenes infection. One strain of Listeria monocytogenes was detected in a smear sample from the inner wall of the refrigerator, and all the strains were ST2 type. Consuming fruits contaminated with Listeria monocytogenes may be the main source of infection. Food safety education for pregnant women and their family members should be strengthened to reduce the risk of infection.

ObjectiveTo evaluate the methodological quality and reporting quality of published guidelines/consensuses on traditional Chinese medicine （TCM）/integrated traditional Chinese and Western medicine diagnosis and treatment of nonalcoholic fatty liver disease （NAFLD）， and to provide a basis for formulating guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD in the future. MethodsDatabases including PubMed， Embase， Web of Science， CNKI， Wanfang Data， and CBM and the websites of China Association of Chinese Medicine and China Association of Integrative Medicine were searched for related articles published up to September 1， 2024. Two clinical researchers independently assessed the methodological quality and reporting quality of the guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD by using Appraisal of Guidelines for Research and Evaluation Ⅱ （AGREE Ⅱ） and Reporting Items for Practice Guidelines in Healthcare （RIGHT）. ResultsA total of nine guidelines/consensuses were included after literature screening， with four guidelines and five expert consensuses. The scores of different domains assessed by AGREE Ⅱ for the nine guidelines/consensuses were as follows： scope and purpose （47.1%）， stakeholder involvement （41.0%）， rigor of development （21.6%）， clarity of presentation （40.2%）， applicability （19.0%）， and editorial independence （19.6%）. The recommendation level of the articles was B level （recommended after revision） for four articles and C level （not recommended） for five articles. The RIGHT assessment showed high reporting rates for “Basic Information” and “Background”， while other areas needed to be improved. Currently， there was no international standard for the guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD， and the quality of these guidelines/consensuses needed to be enhanced to ensure comprehensiveness and credibility. ConclusionThere is still potential for improving the quality of guidelines/consensuses on TCM/integrated traditional Chinese and Western medicine diagnosis and treatment of NAFLD， and AGREE Ⅱ and RIGHT checklists should be strictly followed to ensure the fairness， scientific rigor， and transparency of these guidelines/consensuses.

T-cell acute lymphoblastic leukemia (T-ALL) is a highly aggressive hematologic malignancy with a poor prognosis, despite advancements in treatment. Many patients struggle with relapse or refractory disease. Investigating the role of the super-enhancer (SE) regulated gene ubiquitin-specific protease 20 (USP20) in T-ALL could enhance targeted therapies and improve clinical outcomes. Analysis of histone H3 lysine 27 acetylation (H3K27ac) chromatin immunoprecipitation sequencing (ChIP-seq) data from six T-ALL cell lines and seven pediatric samples identified USP20 as an SE-regulated driver gene. Utilizing the Cancer Cell Line Encyclopedia (CCLE) and BloodSpot databases, it was found that USP20 is specifically highly expressed in T-ALL. Knocking down USP20 with short hairpin RNA (shRNA) increased apoptosis and inhibited proliferation in T-ALL cells. In vivo studies showed that USP20 knockdown reduced tumor growth and improved survival. The USP20 inhibitor GSK2643943A demonstrated similar anti-tumor effects. Mass spectrometry, RNA-Seq, and immunoprecipitation revealed that USP20 interacted with hypoxia-inducible factor 1 subunit alpha (HIF1A) and stabilized it by deubiquitination. Cleavage under targets and tagmentation (CUT&Tag) results indicated that USP20 co-localized with HIF1A, jointly modulating target genes in T-ALL. This study identifies USP20 as a therapeutic target in T-ALL and suggests GSK2643943A as a potential treatment strategy.

ObjectiveTo assess the direct economic burden and influencing factors of road traffic injuries in Shanghai， providing a basis for future prevention of road traffic injuries. MethodsInformation of inpatient cases caused by road traffic injuries was collected from 22 pilot hospitals in Shanghai that participated in the registration and reporting system of injury hospitalizations from 2017 to 2020. The main content of the collected information included basic demographic information， total hospitalization costs for injuries， mode of transportation， cause of injury， nature of injury， location of injury， and hospital level. Univariate analysis was used to analyze the average hospitalization costs and length of hospital stay between different years. Kruskal-Wallis test was used to analyze the median hospitalization costs and the median length of hospital stay between different years， and the median hospitalization costs of different groups. A full subset regression model in multivariate regression was used to explore the main influencing factors of hospitalization costs. ResultsA total of 4 655 patients were hospitalized with road traffic injuries， including 2 675 males （57.47%） and 1 980 females （42.53%）. The average age was （53.84±15.37） years old， with a minimum age of 4 years old and a maximum age of 97 years old. 1 907 patients （40.97%） had non-motor vehicle accidents， and 2 748 patients （59.03%） had motor vehicle accidents. The average hospitalization cost is 23 245.71 yuan， with a median of 9 793.94 yuan. The average length of stay was 13.61 days， with a median stay of 10.00 days. The main factors affecting hospitalization costs included year， nature of injury， location of injury， length of hospital stay， and hospital level. ConclusionRoad traffic injuries seriously affect the health of middle-aged and young people， especially vulnerable road user such as pedestrians and cyclists， causing serious injury and an increase of direct economic burden year by year. Therefore， road traffic injury prevention projects should be actively carried out to reduce the occurrence of injuries.

Objective To investigate the efficacy and safety of subretinal fluid extraction combined with intravitreal conbercept and gas injection in treating polypoidal choroidal vasculopathy(PCV)complicated with serous retinal pigment epithelium detachment(sPED).Methods From July 2019 to February 2021,13 patients(13 eyes)with PCV complicated with sPED who were treated with subretinal fluid extraction combined with intravitreal injection of conbercept and gas in the Weifang Eye Hospital were selected.All affected eyes received at least 3 times(once a month)of intravitreal anti-vas-cular endothelial growth factor(VEGF)(ranibizumab)injections before the surgery,and the treatment was ineffective.The changes in best corrected visual acuity(BCVA),central retinal thickness(CRT),macular foveal PED height and width before and 1 week,1 month,3 months and 6 months after the operation were observed,and the intraoperative and postop-erative complications were recorded.Results The BCVA of the affected eyes 1 week after operation was better than that before operation,and the difference was statistically significant(Z=-3.237,P=0.001).The CRT of the affected eyes at 1 week,1 month,3 months and 6 months after the operation were thinner than that before the operation,and the differ-ence was statistically significant(Z=-3.180,-3.180,-3.110 and-3.180,P=0.001,0.001,0.002 and 0.001).The height and width of PED at 1 week,1 month,3 months and 6 months after the operation were lower than those before the operation,and the differences were statistically significant(all P＜0.05).Thirteen eyes received an average of(4.15±1.40)intravitreal injections(ranibizumab)before the surgery,and the treatment duration was(5.92±3.95)months(equivalent to one injection every 6 weeks).During the 6-month follow-up,13 eyes received an average of(2.31±1.97)intravitreal injections(conbercept)(equivalent to once every 10 weeks).Partial correlation analysis showed a weak positive correla-tion between the increase in BCVA and the decrease in CRT 6 months after operation(r=0.416,P=0.203).There was no significant correlation between the increase in BCVA and the changes in PED height and width 6 months after operation(r=0.218,0.209,P=0.520,0.538).At 1 month after the operation,9 eyes had PED recurrence or different degrees of retinal nerve subepithelial effusion,and PED improved after repeated intravitreal injection of conbercept.At 6 months after opera-tion,subfoveal PED completely disappeared in 3 eyes,and the retina was completely reattached.There was still active exu-dation in the retina of 1 eye.No systemic or severe ocular complications occurred in 13 eyes during the follow-up period.Conclusion Subretinal fluid extraction combined with intravitreal injection of conbercept and gas in the treatment of PCV complicated with sPED can safely and effectively reduce CRT,improve PED,and reduce the damage to the retina caused by long-term PED,but it has no significant effect on the improvement of BCVA at 6 months after the operation.

Objective To investigate the application value of tenofovir alafenamide fumarate(TAF)in patients with first-time hepatitis B virus-related decompensated cirrhosis(HBV-DC)and its impact on renal function and lipid metabolism.Methods A total of 57 patients with first-time HBV-DC who were hospitalized and received TAF antiviral therapy in The Affiliated Hospital of Xuzhou Medical University from January 1,2020 to December 31,2022 were enrolled,and all of them received TAF antiviral therapy.Related data were collected at baseline and at weeks 12,24,and 48 of treatment,including virological and serological indicators,liver and renal function,serum phosphorus,and blood lipids.The paired t-test or single group repeated measures ANOVA were used for comparison of normally distributed continuous data,the Friedman test was used for comparison of non-normally distributed continuous data,and the chi-square test or the Fisher's exact test were used for categorical data.Results A total of 52 patients completed the 48 weeks of follow-up.After 12,24,and 48 weeks of treatment,the patients achieving HBV DNA seroconversion accounted for 38.5%,63.5%,and 84.6%,respectively;the alanine aminotransferase normalization rate were 71.2%,82.7%,and 82.7%,respectively;the proportion of the patients with Child-Pugh class A disease increased to 55.8%,73.1%,and 92.3%,respectively.Within the 48 weeks of treatment,there were significant increases in the levels of cystatin C(χ2=35.163,P＜0.001)and serum phosphorus(F=8.600,P＜0.001)and low-density lipoprotein cholesterol(χ2=10.064,P=0.018).The ratio of total cholesterol/high-density lipoprotein cholesterol decreased continuously from 3.61(2.61～5.84)to 3.27(2.70～4.36)(χ2=5.000,P=0.172).Conclusion TAF can rapidly inhibit HBV replication and significantly improve liver function in HBV-DC patients,with no significant impact on renal function.However,blood lipid should be closely monitored.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:To explore the role of arginine metabolism in the inflammatory response to influenza A virus (FluA) infection.Methods:Eighteen-month-old mice were infected with FluA via nasal drip, with samples collected on the 6th day post-infection. The concentration of cytokines was determined by the Luminex multifactor assay, while the metabolites in bronchoalveolar lavage fluid (BALF) were analyzed using targeted metabolomic method. Correlation analysis was employed to examine the correlation between cytokines and metabolites. Macrophages were infected with FluA at a multiplicity of infection (MOI) of 1 and cultured with different concentrations of arginine for 24 h. The mRNA and protein expression levels of interleukin (IL)-1β, IL-6, tumor necrosis factor α (TNF-α) and IL-10 were detected by real time fluorescence quantitative RT-PCR (qRT-PCR) and Cytometric Bead Array (CBA).Results:In comparison to the control group, the levels of surfactant protein D (SP-D), TNF-α, monocyte chemotactic protein-1 (MCP-1), IL-1α, IL-6, IL-10, recombinant S100 calcium binding protein (S100) A9, interferon inducible protein 10 (IP-10), macrophage inflammatory protein-1α (MIP-1α), matrix metalloprotein-9 (MMP-9), and Complement Factor D in BALF of FluA infection exhibited a significant elevation. The concentrations of arginine, aspartate, citrulline, glutamic acid, ornithine, proline, creatine, and sarcosine in arginine metabolism were up-regulated, which was correlated with most of elevated cytokine levels. The supplementation of arginine after FluA infection significantly decreased the levels of IL-1β, IL-6, and TNF-α, but increased the level of IL-10 in macrophages.Conclusions:Arginine reduces the inflammatory response induced by FluA infection in macrophages, suggesting that it may be a potential intervention target for severe pulmonary inflammation following FluA infection.
