With the social transformation， single women’s reproductive rights have appeared more and more frequently in the public sphere. However， the relevant legal norms have not yet clarified reproductive rights. This paper demonstrated the nature and subjects of reproductive rights， as well as clarified that reproductive rights are human rights owned equally by all natural persons. Judicially， it also analyzed the phenomenon of differential treatment of single women and single widowed women in the realization of their reproductive rights from the judicial practice， explored the main factors for widowed single women to realize their reproductive rights， and compared the possibilities of realizing single reproduction. Conceptually， the main ethical objections against single women’s realization of their reproductive rights were discussed to eliminate the obstacles to single women’s reproductive rights. From the perspective of social reality， the transformation of social factors such as fertility concepts and child-rearing structures were analyzed， to demonstrate the legitimacy and reality of the realization of single women’s reproductive rights.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Hepatocellular carcinoma(HCC),commonly known as primary liver cancer,is a major cause of malignant tumors and cancer-related deaths in China,accounting for approximately 85％of all cancer cases in the country.Several guidelines have been used to diagnose and treat liver cancer.However,these guidelines provide a broad definition for classifying advanced liver cancer,with an emphasis on a singular approach,without considering treatment options for individual patients.Therefore,it is necessary to establish a comprehensive and practical expert consensus,specifically for China,to enhance the diagnosis and treatment of HCC using the Delphi method.The classification criteria were refined for Chinese patients with HCC,and the corresponding optimal treatment regimen recommendations were developed.These recommendations took into account various factors,including tumor characteristics,vascular tumor thrombus grade,distant metastasis,liver function status,portal hypertension,and the hepatitis B virus replication status of patients with primary HCC,along with treatment prognosis.The findings and rec-ommendations provide detailed,scientific,and reasonable individualized diagnosis and treatment strategies for clinicians.

Primary liver cancer (PLC) has the features of insidious onset and difficulties in early diagnosis, with limited and ineffective therapeutic options. Chimeric antigen receptor (CAR) T-cell therapy is a genetically modified T-cell therapy that recognizes tumor-specific antigens and activates T cells to exert a tumor-killing effect. CAR T-cell therapy has made great progress in the treatment of hematological tumors and has achieved a good clinical effect in the field of solid tumors in recent years, and although CAR T-cell therapy has developed from the first to the fifth generation, there are still many challenges in the field of solid tumors. This article comprehensively reviews the mechanisms of CAR T-cell therapy for PLC and related research advances, including the main targets such as GPC3, AFP, MUC1, and NKG2D in CAR T-cell therapy for PLC, CAR T-cell therapy for PLC and oncolytic virus, and combined treatment with immune checkpoint inhibitors, as well as the advances in the biological, preclinical, and clinical studies on these targets and treatment modalities and the challenges and solutions for CAR T-cell therapy in the treatment of PLC, so as to provide a reference for the future clinical development of CAR T-cell therapy in liver cancer.

Hepatocellular carcinoma (HCC) is a type of tumor with a high incidence rate, a low rate of early diagnosis, and poor prognosis, and its development and progression involve many factors. As an important organelle in cells, mitochondria is the "energy factory" of cells and is one of the main sites for the production of reactive oxygen species in vivo, and it also participates in the regulation of cell apoptosis. There are varying degrees of changes in mitochondrial membrane, oxidation respiratory chain, mitochondrial dynamics, mitochondrial DNA, and mitochondrial calcium homeostasis during the development and progression of HCC, and such changes may affect the progression of HCC. This article systematically elaborates on the association between mitochondria and HCC, so as to provide a new direction for the diagnosis and treatment of HCC.

Sodium taurocholate cotransporting polypeptide (NTCP) is not only an important transporter for bile acid absorption into the liver, but also a functional receptor for HBV and HDV, and extensive studies have been performed for its structure, function, gene characteristics, and expression and regulation mechanisms. NTCP is also associated with chronic viral hepatitis, nonalcoholic fatty liver disease, liver fibrosis, primary biliary cholangitis, and hepatocellular carcinoma. This article elaborates on the role of NTCP in various hepatobiliary diseases, so as to provide new direction for the diagnosis and treatment of related diseases.

ObjectiveTo investigate the association of high-density lipoprotein cholesterol (HDL-C) with the prognosis of patients with alcohol-related hepatocellular carcinoma (HCC) after radical treatment. MethodsA retrospective analysis was performed for the clinical data of 43 patients with alcohol-related HCC who were admitted to The Fifth Medical Center of Chinese PLA General Hospital and underwent radical treatment from January 2008 to July 2015, and according to HDL-C level, the patients were divided into normal group with 26 patients and abnormal group with 17 patients. The two groups were compared in terms of basic information, laboratory markers, imaging indices, Barcelona Clinic Liver Cancer tumor stage, and Child-Pugh class of liver function. The t-test 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. The Kaplan-Meier method was used to plot survival curves and the log-rank test was used for comparison between groups. Univariate and multivariate Cox proportional hazards models were used to analyze independent risk factors for prognosis. ResultsThere was a significant difference in prealbumin between the two groups (162.38±60.86 mg/L vs 120.06±64.08 mg/L, t=2.184, P=0.035). Number of tumors (hazard ratio ［HR］=2.839, 95%confidence interval ［CI］: 1.120~7.200,P=0.028), tumor size (HR=2.634, 95%CI: 1.062~6.529,P=0037), and HDL-C level (HR=2.400, 95%CI: 1.040~5.537,P=0.040) were independent risk factors for the overall survival of patients with alcohol-related HCC. There were significant differences in 1-, 3-, and 5-year cumulative survival rates between the normal group and the abnormal group (88.5%/72.4%/55.7% vs 70.6%/43.7%/17.5%, χ2=5.881, P=0.015). ConclusionThe reduction in HDL-C level might indicate poor prognosis of patients with alcohol-related HCC.

Bile acid metabolism, gut microbiota, and bile acid receptors are involved in the development and progression of hepatocellular carcinoma (HCC). There are substantial increases in the levels of some bile acids, such as glycocholic acid, taurocholic acid, and taurochenodeoxycholic acid, in the liver tissue of HCC mice and the serum and feces of HCC patients. Bile acid metabolism due to the imbalance of the abundance of bacteria producing bile salt hydrolases and Clostridium in the intestine and the change in immune microenvironment may also promote the development of HCC. Moreover, some bile acid receptors, such as farnesoid X receptor, G protein-coupled bile acid receptor 1, pregnane X receptor, constitutive androstane receptor, and sphingosine-1-phosphate receptor 2, have been shown to participate in the development and progression of HCC through various pathways. Each link of bile acid metabolism plays a different role in the progression of HCC, and a systematic elaboration of the interaction between these links may help to deepen the understanding of the pathogenesis of HCC and develop the biological targets for early diagnosis, prognosis prediction, and precise treatment.
