As a neglected tropical disease, schistosomiasis remains a major public health challenge in underdeveloped areas, notably Africa. Currently, the national schistosomiasis control programmes in Africa mainly depend on foreign aids; however, conventional international aid models have multiple limitations. To enhance the effectiveness and sustainability of global schistosomiasis control programmes, this article proposes a trinity collaboration model based on international rules, China’s experiences and local needs, which is explained with China aid project of schistosomiasis control in Zanzibar as an example. Based on the successful experiences from the national schistosomiasis control programme in China, this model emphasizes the compliance with World Health Organization guidelines and fully considers local actual needs to promote the effectiveness and sustainability of the schistosomiasis control programme through integrating international resources and promoting China’s experience to meet local needs. The successful practice of the China aid project of schistosomiasis control in Zanzibar provides strong evidence that the model is of great theoretical significance and practical value to improve the efficiency of multilateral collaboration and promote global health governance.

Our study aims at systematically summarizing and evaluating the applications of digital intelligence technologies in the field of rare disease medical care insurance now and in the future and at constructing a conceptual framework for the digital powered mechanism for the medical care insurance for rare diseases. By using Chinese keywords of " rare disease" " medical insurance"" artificial intelligence"" prediction model"" machine learning"" big data"" algorithm" and their English equivalents, we searched the databases of PubMed, Embase, Web of Science, CNKI, Wanfang, and VIP, collected relevant literature, and decided the criteria of inclusion and exclusion. The finding of our study shows that medical care insurance mechanism of rare disease in China faces significant challenges in drug accessbility and the funding sustainability. Meanwhile, our study shows that the digital intelligence technologies have broad potential in applications-in financing, accessbility, payment, and supervision. Specifically, dynamic simulation models and big data analysis can make precise prediction of the demand for funding of medical care insurance. The machine learning algorithms improve the dynamic evaluation of drug safety and cost-effectiveness. The personalized payment models enhance the efficiency in identifying the cohort with high expenditure so as to alleviate fund expenditure pressures. The intelligent monitoring technologies can accurately detect the abnormal behaviors in funds of medical care insurance. These technologies provide systematic and scientific solutions for improving the medical care mechanism for rare diseases. Even though further investigation is needed, the digital intelligence technologies have shown remarkable potential in enhancing the flexibility, efficiency, and sustainability of the medical care insurance system and a promising future in meeting the needs of patients with rare diseases.

Social working memory (SWM)-the ability to maintain and manipulate social information in the brain-plays a crucial role in social interactions. However, research on SWM is still in its infancy and is often treated as a unitary construct. In the present study, we propose that SWM can be conceptualized as having two relatively independent components: "externally oriented SWM" (e-SWM) and "internally oriented SWM" (i-SWM). To test this external-internal hypothesis, participants were tasked with memorizing and ranking either facial expressions (e-SWM) or personality traits (i-SWM) associated with images of faces. We then examined the neural correlates of these two SWM components and their functional roles in empathy. The results showed distinct activations as the e-SWM task activated the postcentral and precentral gyri while the i-SWM task activated the precuneus/posterior cingulate cortex and superior frontal gyrus. Distinct multivariate activation patterns were also found within the dorsal medial prefrontal cortex in the two tasks. Moreover, partial least squares analyses combining brain activation and individual differences in empathy showed that e-SWM and i-SWM brain activities were mainly correlated with affective empathy and cognitive empathy, respectively. These findings implicate distinct brain processes as well as functional roles of the two types of SWM, providing support for the internal-external hypothesis of SWM.

Objective To explore the causal relationship between rheumatoid arthritis(RA)and iron deficiency a-nemia(IDA)in European population by two-sample Mendelian randomization analysis.Methods The single nu-cleotide polymorphisms(SNPs)of RA and IDA were analyzed using public genome-wide association studies(GWAS).The inverse variance weighting method(IVW)was used as the main analysis method to evaluate the causal effect of RA on IDA.MR-Egger method,weighted median method(WM),weighted model method and simple model method were used as regression supplements to evaluate the robustness of sensitivity analysis results.The het-erogeneity function was used to calculate the P-value to test the heterogeneity,and the intercept term intercept was used to test the level pleiotropy.Results In the FINNGEN database at the genome-wide level,strong-related SNPs that removed linkage disequilibrium and met the P＜5.0 × 10-8 by Mendelian randomization analysis were select-ed.After integrating exposure and outcome data,31 SNPs were obtained as the final effective instrumental variables.IVW showed that RA was a risk factor for IDA(the risk of IDA in RA patients was 1.064 times higher than that in non-RA patients,OR=1.064,95％CI:1.028-1.103).The weighted median method and MR-Egger method re-sults supported the positive correlation between RA and IDA.The intercept value was close to 0,indicating that there was no horizontal pleiotropy between exposure and outcome.The heterogeneity function's P＜0.05 indicated that there was heterogeneity between exposure and outcome,but the random effect model test showed P＜0.05,indi-cating that even if there was heterogeneity in causality,the overall trend was stable.Conclusion RA is a risk factor for IDA,and there is a positive correlation between RA and IDA.

Objective To investigate the risk factors for unplanned readmission within 30 days after discharge in cirrhotic patients with esophagogastric variceal bleeding undergoing transjugular intrahepatic portosystemic shunt(TIPS),and to construct a nomogram predictive model.Methods A total of 241 cirrhotic patients who underwent TIPS due to esophagogastric variceal bleeding in Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2020 to June 2023 were enrolled as subjects,and unplanned readmission within 30 days was analyzed.According to the presence or absence of unplanned readmission,they were divided into readmission group with 36 patients and non-readmission group with 198 patients,and related clinical data were collected from all patients.The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data between two groups.A logistic regression analysis was used to identify independent risk factors for unplanned readmission.A nomogram prediction model was constructed,and the receiver operating characteristic(ROC)curve was plotted to assess its discriminatory ability for unplanned readmission;the calibration curve was plotted to evaluate the consistency of the nomogram model in predicting unplanned readmission;the ResourceSelection package of R language was used for the Hosmer-Lemeshow goodness-of-fit test to evaluate the degree of fitting of the mode;the decision curve analysis was used to investigate the practicality of the model.Results Age(odds ratio[OR]=2.664,95%confidence interval[CI]:1.139-6.233,P<0.05),CTP score(OR=1.655,95%CI:1.098-2.495,P<0.05),and blood ammonia(OR=1.032,95%CI:1.016-1.048,P<0.05)were independent risk factors for unplanned readmission within 30 days after discharge in the patients undergoing TIPS.The multivariate analysis showed that for the nomogram predictive model constructed in this study,repeated sampling for 1 000 times using the Bootstrap method was performed for internal validation,and the area under the ROC curve was 0.773,which was significantly higher than that of age(0.582),CTP score(0.675),and blood ammonia(0.641).The calibration curve showed good consistency between the probability of unplanned readmission predicted by the nomogram model and the actual probability,and the Hosmer-Lemeshow goodness-of-fit test showed good degree of fitting(c2=5.647 3,P=0.686 7).Conclusion Age,CTP score,and blood ammonia are independent risk factors for unplanned readmission within 30 days after TIPS,and the nomogram prediction model constructed based on these factors can help to predict the risk of unplanned readmission in TIPS patients and provide an accurate decision-making basis for early prevention.

Objective To investigate the causal relationship between rheumatoid arthritis (RA) and pulmonary hypertension (PH) by the Mendelian randomization design method.Methods The data on single nucleotide polymorphisms (SNPs) of exposure and outcome were obtained by using publicly available ge-nome-wide association studies and the summary analysis was conducted;the inverse variance-weighted (IVW) method as the primary analysis method was used to assess the causal effect of exposure factors (RA) on the outcomes (PH);the MR-Egger regression method,weighted median method (WM),weighted model and sim-ple model were used as supplementary regression explanations to conduct the sensitivity analysis for evalua-ting the robustness of results;the "heterogeneity" function was used to calculate the "P value" for testing the heterogeneity,and the "horizontal pleiotropy" function was used to calculate the "P value" to test the level pleiotropy.Results In the "FINNGEN data" included in the GWAS database,the SNPs had the strong corre-lation after removing the linkage imbalance by Mendelian random analysis and satisfying "P<5×10-8" were selected,the effective instrumental variables were obtained by integrating the exposure and outcome.The IVW results showed that RA was a risk factor for PH (OR=1.295,95％CI:1.053-1.593,P=0.014)."heteroge-neity" function test showed that the results had no heterogeneity (P=0.221);" horizontal pleiotropy" func-tion test showed that the results had no horizontal pleiotropy (P=0.877),and the total results were steady and reliable.Conclusion RA is a risk factor for PH,and RA is positively associated with PH.

Objective:To explore whether transjugular intrahepatic portosystemic shunt (TIPS) can improve the prognosis of esophagogastric variceal bleeding (EGVB) combined with sarcopenia in cirrhotic patients.Methods:A retrospective cohort study was performed. A total of 464 cases with cirrhotic EGVB who received standard or TIPS treatment between January 2017 and December 2019 were selected. Regular follow-up was performed for the long-term after treatment. The primary outcome was transplantation-free survival. The secondary endpoints were rebleeding and overt hepatic encephalopathy (OHE). The obtained data were statistically analyzed. The t-test and Wilcoxon rank-sum test were used to compare continuous variables between groups. The χ2 test, or Fisher's exact probability test, was used to compare categorical variables between groups. Results:The age of the included patients was 55.27±13.86 years, and 286 cases were male. There were 203 cases of combined sarcopenia and 261 cases of non-combined sarcopenia. The median follow-up period was 43 months. The two groups had no statistically significant difference in follow-up time. There was no statistically significant difference in transplant-free survival between the TIPS group and the standard treatment group in the overall cohort ( HR=1.31, 95% CI: 0.97-1.78, P=0.08). The TIPS patient group with cirrhosis combined with sarcopenia had longer transplant-free survival (median survival: 47.76 vs. 52.45, χ2=4.09; HR=1.55, 95 CI: 1.01~2.38, P=0.04). There was no statistically significant difference in transplant-free survival between the two kinds of treatments for patients without sarcopenia ( HR=1.22, 95% CI: 0.78~1.88, P=0.39). Rebleeding time was prolonged in TIPS patients with or without sarcopenia combination (patients without combined sarcopenia: median rebleeding time: 39.48 vs. 53.61, χ2=18.68; R=2.47, 95 CI: 1.67~3.65, P<0.01; patients with sarcopenia: median rebleeding time: 39.91 vs. 50.68, χ2=12.36; HR=2.20, 95 CI: 1.42~3.40, P<0.01). TIPS patients had an increased 1-year OHE incidence rate compared to the standard treatment group (sarcopenia patients: 6.93% vs. 16.67%, χ2=3.87, P=0.049; patients without sarcopenia combination: 2.19% vs. 9.68%, χ2=8.85, P=0.01). There was no statistically significant difference in the long-term OHE incidence rate between the two kinds of treatment groups ( P>0.05). Conclusion:TIPS can significantly prolong transplant-free survival compared to standard treatment as a secondary prevention of EGVB concomitant with sarcopenia in patients with cirrhosis. However, its advantage is not prominent for patients with cirrhosis in EGVB without sarcopenia.

Objective:To summarize the clinical manifestations and diagnostic methods of adult neuronal intranuclear inclusion disease (NIID), improve understanding of the disease, and avoid misdiagnosis.Methods:Clinical data of 8 adult NIID patients in the Hunan region were collected, and their clinical manifestations, cranial imaging, genetic testing, skin biopsy, and other characteristics were analyzed.Results:Among the 8 patients, 4 were males and 4 were females; The initial symptoms of 2 patients were dizziness, 2 were mental abnormalities, 2 were stroke like attacks, 1 was urinary incontinence, and 1 was limb tremor; Six patients experienced slow progression of the disease, while two patients experienced sudden progression after several years of slow progression; The GGC repeat amplification mutation in the 5′untranslated region of the NOTCH2NLC gene, as well as the lace like sign in the brain cortex medullary junction on diffusion-weighted imaging (DWI) and the presence of eosinophilic transparent inclusion bodies in the nucleus on skin biopsy, were helpful in diagnosing NIID.Conclusions:The clinical manifestations of NIID are highly heterogeneous, and some patients have rare initial clinical symptoms, which are prone to misdiagnosis and missed diagnosis. It is necessary to combine imaging, genetic testing, and skin biopsy to confirm the diagnosis; Some patients may experience sudden progression and poor prognosis after years of slow progression.

Anti γ-aminobutyric acid B receptor encephalitis is a type of autoimmune encephalitis characterized by the production of self specific antibodies in cerebrospinal fluid and/or serum, with seizures, memory loss, and consciousness disorders as the main clinical manifestations. This type of encephalitis caused by autoantibodies has the same pathological characteristics as other peripheral encephalitis. There are many different etiologies and pathophysiological processes that lead to the occurrence of limbic encephalitis, and it is necessary to understand their heterogeneity in order to find effective treatment methods. This article will systematically review the epidemiology, pathogenesis, clinical characteristics, diagnosis, treatment, and prognosis of anti γ-aminobutyric acid B receptor encephalitis, aiming to enhance clinical doctors' understanding of this disease and provide reference for clinical decision-making.

Objective To investigate whether lidocaine can reverse Kupffer cell dysfunction in diabetic mice, as well as the mechanism of lidocaine in affecting liver abscess formation by improving the phagocytic function of Kupffer cells. Methods C57BLKS/J db/db mice were divided into diabetes control group and diabetes+lidocaine group, and C57BLKS/J db/m mice were divided into non-diabetes control group and non-diabetes+lidocaine group, with 5 mice in each group. All mice were fed with the suspension of Klebsiella pneumoniae . Kupffer cells were collected from each group and were cultured in vitro; an electron microscope was used to measure the change in ultrastructure, and Kupffer c ells were measured in terms of the levels of inflammatory mediators, the expression level of intercellular adhesion molecule-1 (ICAM-1), the chemotactic function of neutrophils, and phagocytic function; liver abscess formation was also observed. The Kruskal-Wallis H test was used for comparison of continuous data between multiple groups, and the Mann-Whitney U test was used for further comparison between two groups; the chi-square test was used for comparison of categorical data between groups. Results Compared with the non-diabetic mice, the diabetic mice had significant reductions in mitochondria and rough endoplasmic reticulum, endoplasmic reticulum dilation, mitochondrial swelling, and an increase in lipid droplets in Kupffer cells. Compared with the non-diabetes control group, the diabetes control group had significant increases in the levels of nitric oxide (NO) (4.95±0.06 μmol/L vs 1.34±0.13 μmol/L, P < 0.05), interleukin-6 (IL-6) (740.04±8.58 pg/mL vs 515.77±4.62 pg/mL, P < 0.05), tumor necrosis factor-α (TNFα) (774.23±7.98 pg/mL vs 461.51±1.76 pg/mL, P < 0.05), interferon gamma (IFNγ) (842.33±14.79 pg/mL vs 542.47±6.75 pg/mL, P < 0.05), and ICAM-1 (2.40±0.02 vs 1.33±0.01, P < 0.05) in Kupffer cells, a significant increase in neutrophil chemotaxis (100.80±10.18 vs 13.80±3.70, P < 0.05), and a significant reduction in phagocytic capacity (9.86±1.82 vs 60.00±3.54, P < 0.05), with no effect on liver abscess formation (40% vs 0, P > 0.05). Compared with the diabetes control group, the diabetes+lidocaine group had significant reductions in the levels of NO (3.35±0.28 μmol/L vs 4.95±0.06 μmol/L, P < 0.05), IL-6 (688.42±36.34 pg/mL vs 740.04±8.58 pg/mL, P < 0.05), TNFα (631.15±4.30 pg/mL vs 774.23±7.98 pg/mL, P < 0.05), IFNγ (704.56±3.64 pg/mL vs 842.33±14.79 pg/mL, P < 0.05), and ICAM-1 (1.50±0.02 vs 2.40±0.02, P < 0.05) in Kupffer cells, a significant reduction in neutrophil chemotaxis (33.40±5.60 vs 100.80±10.18, P < 0.05), and a significant increase in phagocytic capacity (49.20±2.59 vs 9.86±1.82, P < 0.05), with no effect on liver abscess formation (0 vs 40%, P > 0.05). Conclusion Lidocaine can inhibit Kupffer cell inflammatory response and improve the phagocytic function of Kupffer cells in diabetic mice, thereby exerting a protective effect on Kupffer cells, but it had no effect on liver abscess formation.
