ObjectiveTo evaluate the public health governance capacity in Jiangsu Province and provide an optimized pathway for the construction of a “strong, rich, beautiful, and high-quality” new Jiangsu. MethodsA total of 806 policy documents, 658 public information reports, and 148 research literatures related to public health governance capacity in Jiangsu Province from January 1995 to December 2023 were collected. The status of current public health goverance was assessed based on the evaluation criteria suitable for public health systems, and the strengths and the weaknesses of the system were identified. ResultsThe public health governance capability of Jiangsu Province was scored at 738.3 points, ranking 3rd nationally. Maternal health care and emergency response capacities achieved leading positions nationwide, both ranking 2nd. Jiangsu had exhibited a standardized guidance in the strategic level, a well-established management mechanism, an extensive coverage in information collection, and a scientifically established health targets setting. However, bottlenecks remained, including an unclear division of responsibilities across organizational departments, an insufficient public-health workforce, the absence of a stable growth mechanism for government funding investment, and difficulties in promptly identifying public needs. ConclusionJiangsu’s public-health system demonstrates leading nationally, yet several components remain underdeveloped. Future efforts should consolidate advantages while addressing weaknesses, further diversify content and forms, establish a stable funding increase mechanism, and clarify departmental functions, thereby providing solid health support for realizing the developmental goals of a “strong, rich, beautiful and high-quality” new Jiangsu.

ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Objective To investigate the temporal changes in pathological damage and macrophage polarization in liver and spleen tissues of mice infected with Angiostrongylus cantonensis, and to preliminarily unravel the peripheral immune responses during the early stage of A. cantonensis infection. Methods Forty female BALB/c mice at ages of 6 to 8 weeks were randomly divided into four groups, including the control group and 7-, 14-, and 21-day infection groups, with 10 mice in each group. Each mouse in the infection groups was inoculated with 30 third-stage (L3) larvae of A. cantonensis by oral gavage, and five mice were randomly selected from each infection group on days 7, 14, and 21 post-infection, while mice in the control group were given the same volume of physiological saline and five mice were randomly selected from the control group on the day of oral gavage. Mouse liver and spleen tissues were sampled. The histopathological changes of mouse liver and spleen tissues were observed using hematoxylin and eosin (HE) staining, and the percentage of positive staining area and the co-localization positive rates of the macrophage surface antigens F4/80, CD86, and CD206 were quantified in mouse liver and spleen tissues using immunohistochemical and immunofluorescence staining. In addition, five mice were collected from each infection group on days 7, 14, and 21 post-infection, and five mice were collected from the control group on the day of oral gavage. Mouse liver and spleen tissues were sampled for detection of macrophage markers CD86 and CD206 and macrophage phenotyping using flow cytometry, and the expression of M1 macrophage markers, including inducible nitric oxide synthase (Nos2), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and M2 markers, including arginase 1 (Arg1), mannose receptor C-type 1 (Mrc1) and chitinase-like protein 3 (Chil3) was quantified in mouse liver and spleen tissues using real-time quantitative PCR (RT-qPCR) assay. Results Proliferative lesions of the hepatocyte were observed in mouse liver tissues and the follicular structures of the mouse spleen white pulp were disrupted 21 days post-infection with A. cantonensis. Immunohistochemical staining showed that there were significant differences in the percentages of F4/80, CD86 and CD206 positive staining areas in the liver and spleen tissues among the four groups of mice (F = 242.40, 197.14, 183.19, 157.65, 242.35 and 146.24; all P values < 0.001), and the percentages of positive staining in the liver and spleen tissues of mice in the 14-day infection group [(4.45 ± 0.51)%, (3.74 ± 0.67)%, (8.32 ± 0.72)%, (16.56 ± 1.14)%, (11.62 ± 0.52)%, and (8.29 ± 0.72)%, respectively] and the 21-day infection group [(3.70 ± 0.11)%, (3.22 ± 0.43)%, (11.53 ± 1.03)%, (12.59 ± 1.05)%, (9.02 ± 0.83)%, and (11.67 ± 1.10)%, respectively] were higher than in the control group [(0.35 ± 0.16)%, (0.40 ± 0.02)%, (0.93 ± 0.05)%, (2.78 ± 0.26)%, (2.33 ± 0.20)%, and (1.85 ± 0.20)%, respectively] (all P values < 0.05). Immunofluorescence staining showed significant differences in the positive rates of F4/80 co-localization with CD86 and CD206 in mouse liver and spleen tissues among the four groups (F = 24.42, 25.28, 54.51 and 130.55; all P values < 0.001). Flow cytometry detected significant differences in the proportions of CD86⁺ and CD206⁺ macrophages in mouse liver and spleen tissues among the four groups (F = 67.98, 18.41, 29.77, 172.80; all P values < 0.001), and the proportions of CD206⁺ macrophages in the liver and spleen of the 21-day infection group were significantly higher than those in the control group [(9.25 ± 2.55)% vs (3.83 ± 0.72)%, and (4.22 ± 0.56)% vs (0.47 ± 0.18)%, respectively] (both P values < 0.05). In addition, RT-qPCR assay quantified significant differences in the relative mRNA expression of M1 macrophage markers (IL-1β, TNF-α and Nos2) and M2 macrophage markers (Arg1, Chil3 and Mrc1) in mouse liver and spleen tissues among the four groups (F = 41.30, 31.82, 199.33, 19.96, 62.01, 119.76, 23.67, 95.90, 72.27, 82.59, 123.41 and 29.75; all P values < 0.05). Conclusions A. cantonensis infection may cause progressive pathological damage in mouse liver and spleen tissues, accompanied by dynamic temporal changes in macrophage polarization. M1 macrophage polarization predominates at the early stage of A. cantonensis infection and shifts towards M2 polarization at the later stages, suggesting that M2 polarization may participate in immune regulation at late stages of A. cantonensis infection by suppressing excessive inflammatory responses and promoting tissue repair.

ObjectiveTo explore the effectiveness of traditional Chinese medicine （TCM） chronic disease management programme in preventing postoperative recurrence of colorectal polyps. MethodsThe clinical data of 447 postoperative colorectal polyp patients were retrospectively collected， and the patients were divided into an exposure group and a control group taking the acceptance of TCM chronic disease management programme as exposure factor， and the polyp recurrence rate as the main outcome indicator， comparing the differences in baseline characteristics， outcome events， and safety assessment between the two groups， and conducting correlation analysis between the length of medication and polyp recurrence. Multifactorial logistic regression was used to analyse the effects of receiving the TCM chronic disease management programme （TCM treatment and life management for spleen deficiency and dampness stasis syndrome， dampness and stasis obstruction in collaterals syndrome， and intestinal dampness and heat syndrome）， gender， age， co-morbidities， TCM syndrome， and dietary and exercise factors on the outcome events. ResultsAmong 257 postoperative patients with colorectal polyps， there were 172 in the exposure group and 85 in control group. The recurrence rate of polyps in exposure group was 22.7% （39/172）， while the recurrence rate in control group was 57.6% （49/85）， and the difference between groups was statistically significant （P＜0.01）. The diameter of recurrent polyps in exposure group （median= 4.0 mm） was smaller than that in control group （median= 5.0 mm， P＜0.01）. The correlation analysis between the duration of medication taking and the recurrence of polyps in the spleen deficiency and dampness stasis syndrome group showed Phi value as -0.345 （P＜0.001）； the correlation analysis within the group of dampness and stasis obstruction in collaterals syndrome showed Phi value as -0.361 （P＜0.05）， indicating a negative correlation between the duration of medication taking and polyp recurrence. The results of multivariate logistic regression analysis indicated that the positive effect of accepting TCM chronic disease management programme on preventing polyp recurrence is statistically significant （OR=0.224， P＜0.01）. ConclusionAccepting TCM chronic disease management programme for colorectal polyps can help reducing the recurrence rate after polyp surgery， which is a protective factor for patients to the outcome event.

Five novel nor-eremophilane-type sesquiterpenoids, peniroqueforins E-H and J (1-4 and 7), two new eremophilane-type sesquiterpenoids, peniroqueforins I and K (5 and 8), and a new eudesmane-type sesquiterpenoid, peniroqueforin L (9), along with four known compounds (6 and 10-12), were isolated and characterized from fungus Penicillium roqueforti (P. roqueforti). The structures and absolute configurations of these compounds were determined through comprehensive spectroscopic analyses, electronic circular dichroism (ECD) data analyses, and single-crystal X-ray diffraction methods. The anti-multi-drug resistance (MDR) cancer activity of these compounds was evaluated using SW620/Ad300 cells. Notably, the half maximal inhibitory concentration (IC₅₀) value of paclitaxel (PTX) combined with 1 in SW620/Ad300 cells was 50.36 nmol·L^-1, which was 65-fold more potent than PTX alone (IC₅₀ 3.26 μmol·L^-1). Subsequent molecular docking studies revealed an affinity between compound 1 and P-glycoprotein (P-gp), suggesting that this nor-eremophilane-type sesquiterpenoid (1) could serve as a potential lead for MDR reversal in cancer cells through P-gp inhibition.

[摘 要] 目的：探究2'-岩藻糖基乳糖（2'-FL）对小鼠免疫检查点抑制剂（ICI）相关结肠炎（ICIC）的作用及其机制。方法：用随机数字表法将BALB/c小鼠随机分为对照组、葡聚糖硫酸钠（DSS）组、ICIC组、ICIC + 2'-FL组。DSS组连续7 d自由摄取含3.5% DSS的饮用水诱导结肠炎；ICIC组在摄取含3.5% DSS的饮用水的同时在实验第0天和第4天通过腹腔注射细胞毒性T淋巴细胞相关抗原4抗体（CTLA⁃4抗体，剂量为150 µg/只）构建ICIC模型；ICIC + 2'-FL组在ICIC造模同时从实验开始每日灌胃给予2'-FL[150 mg/(kg·d）]。统计分析小鼠体质量和疾病活动性评分（DAI）变化。第7天处死小鼠，测量结肠长度，用H-E染色法观察各组结肠组织学形态变化，用免疫组织化学（IHC）法检测CD3+ T细胞和CD19+B细胞在结肠组织中的浸润情况，用转录组学方法对结肠组织进行RNA测序，统计分析各组结肠组织中的差异表达基因（DEG）并进行基因本体论（GO）功能注释和京都基因与基因组百科全书（KEGG）富集分析。结果：与对照组和DSS组比较，ICIC组小鼠体质量明显下降、DAI评分上升、结肠长度更短（均P < 0.05），结肠黏膜完整性受损，呈现典型的溃疡性病变；与ICIC组比较，ICIC + 2'-FL组小鼠体质量下降显著缓解、DAI评分降低，结肠长度恢复（均P < 0.05)。转录组学检测结果显示，与ICIC组相比，2'-FL处理组有51个DEG，GO功能注释和KEGG富集分析提示，2'-FL缓解ICIC样症状与B细胞受体、B细胞增殖调控、炎症反应和修复相关通路的上调有关。结论：人乳寡糖2'-FL可显著缓解ICIC的病理进程，其可能通过B细胞受体相关信号通路及与炎症反应和修复相关通路减轻ICIC小鼠结肠组织的损伤。

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective:To carry out carrier screening among people of childbearing age, detect the pathogenic genes of monogenic genetic diseases and analyze the carrier status of pathogenic variants, so as to provide fertility guidance and intervention measures for high-risk families.Methods:From August 2022 to August 2023, 1 533 families of childbearing age who met the criteria were recruited in the Chinese PLA General Hospital, including a total of 3 044 subjects. According to the standard enrollment procedure, 223 genes (197 autosomal recessive genes and 26 X-linked genes) of the subjects were tested. According to the screening results, genetic counseling and fertility guidance were provided to the subjects. Invasive prenatal diagnosis was performed for high-risk couples (both couples being carriers of the same autosomal recessive disease gene or the woman was a carrier of X-linked disease gene), and their pregnancy pattern, outcome and offspring phenotype were followed up.Results:(1) A total of 3 044 cases from 1 511 couples and women of childbearing age from 22 families were included for carrier screening. Totally 1 503 families chose simultaneous screening and 30 families chose sequential screening out of the 1 533 families. Among the 3 044 subjects, 1 603 individuals carried at least one pathogenic or likely pathogenic variant, and the overall carrier rate was 52.66% (1 603/3 044). A total of 2 292 pathogenic or likely pathogenic variants were detected, and 0.75 variants (2 292/3 044) were detected per capita. (2) The three genes with the highest carrier rates were GJB2 (8.67%, 264/3 044), CYP21A2 (3.19%, 97/3 044) and PAH (3.09%, 94/3 044). There were 32 genes with a carrier rate ≥1/200, 17 genes with a carrier rate ≥1/100, and 7 genes with a carrier rate ≥1/50. (3) Thirty-eight high-risk families were identified. After excluding G6PD gene mutation, there were 33 high-risk families, of which 25 couples were carriers of the same autosomal recessive gene, 9 women were carriers of X-linked gene, and 1 family was double high-risk couple with both autosomal recessive and X-linked gene. After further excluding the GJB2 c.109G>A mutation, 21 high-risk families were identified. Preimplantation genetic testing for monogenic disease was performed in 12 families after genetic counseling. Prenatal diagnosis was completed in 4 out of 5 high-risk families who conceived naturally. Two fetuses carried the parental variants and terminated the pregnancy, one fetus did not carry the parental variants but was induced due to trisomy 21 syndrome, and one fetus was a carrier of congenital disorders of glycosylation type 1a.Conclusions:Carrier screening effectively identifies high-risk genetic disease families and provides reproductive guidance to prevent the birth of affected children. However, establishing multidisciplinary team is essential for managing complex cases. Implementation should prioritize prenatal institutions with genetic counseling or diagnostic expertise for monogenic disorders or established referral networks.

Objective:To evaluate the effectiveness and safety of belumosudil for the treatment of chronic graft-versus-host disease (cGVHD) .Methods:We retrospectively collected data on patients with cGVHD who received belumosudil at Ruijin Hospital Affiliated to Shanghai Jiaotong University School of Medicine from May 2023 to March 2024. The study endpoints were overall response rate (ORR), organ-specific response rates, time to response (TTR), changes in Lee Symptom Scale (LSS) scores, tapering or discontinuation of corticosteroid treatment, failure-free survival (FFS), and adverse events.Results:The study included 20 patients with cGVHD who received belumosudil, of whom 15 were men and 5 women. The median age was 34.5 (12-67) years, and three patients were under 18 years old. The median follow-up duration was 5.0 (1.4 - 9.8) months. All patients had severe cGVHD, and 18 (90.0%) showed involvement of at least four organs. The median number of prior treatment lines was 4, and 15 patients (75%) had previously received ruxolitinib. All patients received 200 mg of belumosudil once daily in combination with other cGVHD systemic therapies. The ORR was 90.0% (95% CI: 68.3%-98.8%), and all responses were partial responses. The median TTR was 1.6 (0.9 - 8.4) months. The LSS scores improved in a clinically meaningful way in 80.0% (16/20) of the patients within 3 months. The corticosteroid dose was reduced in 42.6% (6/14) of the patients. The 3-month FFS was 79.6% (95% CI: 61.4%-100.0%). Most adverse events were grade 1 or grade 2, and two patients (10.0%) experienced grade 3 or higher-grade adverse events. Conclusions:In the real-world setting, belumosudil demonstrated good effectiveness and safety in patients with cGVHD with a history of severe disease and multiorgan involvement.

Objective Tetanus is a serious infectious diseases with high mortality,which is an important global public health issue.This study aims to analyze the epidemiological burden and changing trends of tetanus in China from 1990 to 2021,providing a basis for disease prevention and control.Methods Epidemiological indicators and global socio-demographic index(SDI)related to tetanus in China were retrieved and collected from the 2021 Global Burden of Disease database(GBD 2021).The trend analysis of the incidence rate,mortality rate and disability-ad-justed life years(DALYs)rate of tetanus in China from 1990 to 2021 was conducted by Joinpoint 5.3 software.Results From 1990 to 2021,the age-standardized incidence rate(ASIR),age-standardized mortality rate(ASMR),and age-standardized disability-adjusted life years(DALYs)rate of tetanus in China decreased significantly(average annual percent change[AAPC]＜0,P＜0.001),with males being significantly higher than females.The crude incidence rate,crude mortality rate,and crude DALYs rate for all age groups showed overall declining trends,with the lar-gest decline in the 0-14 years age group.In 2021,the crude incidence rate,crude mortality rate,and crude DALYs rate of tetanus in the population aged 70-years were higher than those in the population aged 0-14,15-49,and 50-69 years groups.The ASIR,ASMR,and age-standardized DALYs rate of tetanus in China in 2021 were lower than the global level,only higher than those in the high SDI regions.Conclusion From 1990 to 2021,the disease burden of tetanus in China varied with gender and age,with an overall declining trend over time.It is necessary to strengthen tetanus health education for males and the ≥70 years population,and to improve the overall level of pri-mary prevention measures for tetanus.
