Both porto-sinusoidal vascular disorder and hepatic sinusoidal obstruction syndrome belong to hepatic vascular diseases， and they have differences in etiology， clinical manifestations， treatment， and prognosis. However， recent research evidence has gradually shown that the association between porto-sinusoidal vascular disorder and hepatic sinusoidal obstruction syndrome has not been fully understood， suggesting that they may be two different manifestations of the same disease. This article reviews the association between these two diseases and related research evidence.

Cavernous transformation of the portal vein （CTPV） is a significant challenge in clinical practice. In recent years， transjugular intrahepatic portosystemic shunt has gradually been applied in the treatment of CTPV patients， but it had a technical success rate and a relatively high surgical risk. The scholars have adopted various modified techniques of portosystemic shunt to improve success rate and safety. However， for CTPV patients with extensive occlusion of the main portal vein， this surgery remains difficult， and individualized strategies for portosystemic shunt should be formulated. This article reports a case of CTPV treated by transjugular extrahepatic portosystemic shunt assisted by endoscopic ultrasound-guided portal vein localization， in order to explore a new pathway for the clinical management of patients with CTPV.

Objective:To clarify the changes in incidence and mortality of various cancers based on analysis on registration data of malignant tumor incidence and mortality from Dehui City and Yanji City in Jilin Province.Methods:The incidence and mortality data of malignant tumors from 2009 to 2016 in Dehui City and Yanji City in Jilin Province,were collected from the Chinese Cancer Registry Annual Report published by the National Cancer Center.The number of cases,deaths,crude incidence rate,crude mortality rate,age-standardized incidence rate(ASIR),age-standardized mortality rate(ASMR),and annual percentage change(APC)of the malignant tumors were analyzed by cancer sites and genders.Results:From 2009 to 2016,the CIR of malignant tumors in Dehui City(APC=1.2%,P=0.019)and Yanji City(APC=3.6%,P=0.058)showed an increasing trend.After standard population age adjustment,the ASIR in males in Dehui City showed a significant decline(APC=-5.7%,P=0.021),while the ASIR in females exhibited an overall downward trend,but the difference was not significant(APC=-2.2%,P=0.111).In Yanji City,the ASIR in males(APC=-1.4%,P=0.535)and females(APC=0.0%,P=0.988)showed no significant changes.The CMR of malignant tumors in Dehui City(APC=1.9%,P=0.001)and Yanji City(APC=5.9%,P=0.001)showed a continuous upward trend.After age-standardization,the ASMR in males(APC=-3.1%,P=0.100)and females(APC=-4.2%,P=0.053)in Dehui City,as well as in males(APC=-1.3%,P=0.438)in Yanji City,showed a slight downward trend.Although the ASMR in females in Yanji City showed a slight increase,the difference was not statistically significant(APC=0.5%,P=0.838).In 2016,the most common malignant tumor in terms of both incidence and mortality in Dehui City was lung cancer,with a CIR of 60.76/100 000 and a CMR of 46.96/100 000.In Yanji City,the most common malignant tumor was liver cancer,with a CIR of 49.04/100 000 and a CMR of 51.09/100 000.Conclusion:Lung cancer,liver cancer,and gastric cancer are the major malignant tumors threatening residents in Dehui City,Yanji City,and even the entire Jilin Province,and should be prioritized in cancer prevention and control efforts.Early diagnosis and treatment should be strengthened.

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.

ObjectiveTo investigate the risk factors for survival after transjugular intrahepatic portosystemic shunt （TIPS） in patients with liver cirrhosis and esophagogastric variceal bleeding （EGVB）， and to establish a predictive model for survival after TIPS. MethodsClinical data were collected from 352 patients with liver cirrhosis and EGVB who underwent TIPS in Department of Gastroenterology， Affiliated Drum Tower Hospital of Nanjing University Medical School， from January 2015 to December 2018， and the patients were randomly divided into training group （n=248） and validation group （n=104） at a ratio of 7∶3. The Cox regression analysis was used to identify the independent risk factors for survival after TIPS， and a nomogram predictive model was established. The index of concordance （C-index） and the receiver operating characteristic （ROC） curve were used to assess the discriminatory ability of the model， and the calibration curve was used to assess the predictive value of the model. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum 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. The Kaplan-Meier analysis was used to calculate cumulative survival rate. ResultsFor the patients in the training group， the 1-，3-， and 5-year cumulative survival rates were 91.1%，79.5%， and 77.0%， respectively. The multivariate Cox regression analysis showed that age （hazard ratio ［HR］=1.047， 95% confidence interval ［CI］：1.032‍ ‍—‍ ‍1.092，P<0.001）， MELD score （HR=1.127，95%CI：1.003‍ ‍—‍ ‍1.268，P=0.045）， and serum sodium （Na） （HR=0.928，95%CI：0.878‍ ‍—‍ ‍0.981，P=0.008） were independent influencing factors for survival， and a predictive model and a nomogram were established based on these factors. The predictive model had a C-index of 0.760 in the training group and 0.757 in the validation group. In the training group， the nomogram had an area under the ROC curve of 0.807，0.788， and 0.787， respectively， in predicting 1-，3-， and 5-year cumulative survival rates. The calibration curve showed relatively high consistency between the results predicted by the nomogram and the actual results. ConclusionA nomogram model is established based on age， MELD score， and Na for predicting survival after TIPS in patients with liver cirrhosis and EGVB， and this model has good discriminatory ability and accuracy.

Objective:To investigate the curative effect and possible mechanism of rifaximin treatment on monocrotaline-induced hepatic sinusoidal obstruction syndrome (HSOS) in mice.Methods:Twenty-four male C57BL/6J mice were divided into three groups and treated with solvent control, monocrotaline, and rifaximin, respectively. The histopathological changes of the liver and intestine were observed by hematoxylin-eosin staining. The differences were compared in liver parameters, serum liver enzymes, inflammatory factors, apoptotic factors, gut microbiota, and gut tight junction proteins among three groups of mice. The inter-group comparison was conducted using a t-test and one-way analysis of variance.Results:The rifaximin-treated group had significantly improved liver histopathology. The serological levels of alanine aminotransferase and aspartate aminotransferase were (559.04±89.42) U/L and (676.90±106.25) U/L, respectively, which were significantly lower than those in the PA-HSOS model group [(846.05±148.46) U/L and (953.87±58.10) U/L, P<0.05], and were accompanied by lower levels of apoptotic cells and inflammatory factors. Additionally, the rifaximin-treated mice group gut microbiota had higher diversity compared with the PA-HSOS group ( P<0.05), and the Shannon index was 7.77±0.10 and 7.16±0.07, respectively, indicating apparent differences in microbiota among different groups. The abundance of Firmicutes in the rifaximin group was 39.58%±0.56%, which was significantly higher than that in the model group (24.25%±0.64%, P<0.05), while the abundance of Bacteroidetes was 54.7%±0.41%, which was significantly lower than that in the model group (70.92%±0.49%, P<0.05). Simultaneously, the expressions of gut tight junction proteins ZO-1 and Occludin showed an upward trend and validated transcription levels compared to the model group following rifaximin intervention ( P<0.05). Conclusion:Rifaximin can alleviate monocrotaline-induced hepatic sinusoidal obstruction syndrome in mice, and its mechanism may be via gut microbiota regulation, which in turn plays a role in improving intestinal barrier function.
