Liver failure is a familiar severe disease, with no good clinical early diagnostic indicators and treatment methods. Studies have shown that non-encoding RNA (ncRNA) characterized by microRNA (miRNA) and long non-coding RNA (lncRNA) can be used not only as an early diagnostic indicator of liver failure, but also play a key regulatory role in an inflammatory response to liver failure, hepatocyte death and hepatocyte regeneration. Simultaneously, the epigenetic regulation of ncRNA also participates in the initiation and progression of liver failure. This article reviews the relationship between miRNA, lncRNA, and liver failure to find new targets for the diagnosis and treatment of liver failure.

【Objective】 To explore a transfusion therapeutic plan for hemolytic disease of the newborn(HDN) caused by anti-c antibodies in mother of Asian-type DEL. 【Methods】 The ABO blood type and Rh phenotype of the mother and child were determined using the saline tube method. The mother′s RhD negativity was confirmed through classical anti-human globulin testing and RhD adsorption-elution test. The mother′s unexpected antibodies were screened and their titers were measured using classical anti-human globulin testing, antibody card test and polyamine method. Cross-matching was conducted. The three hemolysis tests were performed by antibody card test. The mother′s RHD gene typing was conducted using a commercially available RHD negative identification gene detection kit (PCR-SSP method). 【Results】 The mother exhibited a CCee Rh serological phenotype, and the DEL gene test confirmed the presence of RHD*1227A, indicating the production of anti-c antibodies. The infant displayed a DCcEe Rh serological phenotype, positive for direct antiglobulin test and red cell elution. Based on the mother′s obstetric history, clinical manifestations of the infant and blood examination results, the diagnosis was HDN caused by anti-c antibodies. 【Conclusion】 For infants with HDN caused by anti-c antibodies in mother of Asian-type DEL, DCCee Rh phenotype red blood cell transfusion is recommended, while CCee Rh phenotype deglycerolized red blood cell transfusion is recommended for the mother.

ObjectiveTo investigate the effect of human umbilical cord mesenchymal stem cells (hUCMSCs) in the treatment of mice with liver fibrosis and its mechanism. MethodsA total of 18 specific pathogen-free C57BL/6 mice, aged 6 weeks, were selected and divided into control group (n=6), carbon tetrachloride (CCl4) model group (CCl4 group, n=6), and hUCMSCs treatment group (MSC group, n=6) using a random number table. The mice in the CCl4 group and the MSC group were given intraperitoneal injection of CCl4 solution to establish a mouse model of liver fibrosis, while those in the control group were injected with the same dose of corn oil, and the mice in the MSC group were injected with hUCMSCs via the caudal vein during the injection of CCl4. At the end of week 8, mouse serum was collected, and the mice were sacrificed to collect and fix the liver. Enzyme-linked immunosorbent assay was used to measure the levels of inflammatory factors; an automatic biochemical detector was used to measure liver function parameters; HE staining, Masson staining, Sirius Red staining, and α-SMA immunofluorescence assay were used to evaluate liver fibrosis. Hepatic stellate cells (HSCs) stimulated by TGF-β were co-cultured with hUCMSCs in the medium with or without chitinase-3 like-protein-1 (CHI3L1), and Western blot was used to measure the expression levels of proteins. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the Dunnett’s t-test was used for further comparison between two groups. ResultsMasson staining and Sirius Red staining showed that the CCl4 group had a significantly higher degree of fibrosis than the control group (both P<0.05), and the MSC group had significant alleviation of fibrosis compared with the CCl4 group (both P<0.05). Compared with the control group, the CCl4 group had significant increases in the levels of interleukin-1β, interleukin-6 (IL-6), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) (all P<0.05), and compared with the CCl4 group, the MSC group had significant reductions in the levels of IL-6, AST, ALT, and ALP (all P<0.05). The CCl4 group had significantly higher expression levels of CHI3L1 and α-SMA than the control group and the MSC group (all P<0.05). The cell culture experiment showed that the MSC+HSC group had a significantly higher expression level of Bax than the HSC group and the MSC+CHI3L1 group (both P<0.05), suggesting that CHI3L1 reversed the pro-apoptotic effect of MSC on activated HSCs. ConclusionThis study shows that hUCMSCs can improve liver fibrosis in mice, possibly by inhibiting CHI3L1 to promote the apoptosis of HSCs.

Radiation induced lung injury (RILI) is a serious complication in patients received thoracic radiotherapy. The main clinical symptom of RILI includes short of breath, low fever and cough, seriously affect the survival of patients. How to better prevent and treat RILI is an urgent problem. Target theory, cytokine theory, free radical theory, and vascular endothelial cell damage theory are the main mechanisms of RILI. Among them, reactive oxygen species (ROS) produced during radiotherapy can induce tissue damage throughout the course of RILI, and have a direct effect on both radiation pneumonitis and radiation-induced lung fibrosis. Anti-oxygen therapy including thiol compounds, antioxidant enzymes, and plant antioxidants have been applied in the prevention and treatment of RILI. This article reviews the research and application of antioxidant therapy in RILI.

Head and neck tumors often have complex anatomical structures and are adjacent to important organs. Radiation injury caused by conventional radiotherapy technology is the main dose-limiting factor. Carbon ion beam has become the most ideal radiation to replace photon due to its excellent relative biological effect and Bragg peak. By 2019, 32 000 people worldwide have received carbon ion radiotherapy (CIRT). Despite the efficient tumor killing ability of this technology, radiation injury cannot be avoided. This article reviews the types and incidence of moderate to severe radiation injury caused by CIRT in head and neck cancer to provide a comprehensive understanding of the potential risks in CIRT.

OBJECTIVETo investigate the effects of losartan on mRNA expression of myocardial sarcoplasmic reticulum calcium handling proteins (SERCA2, RyR2 and PLB) and the role of which in prevention of chronic heart failure in rabbit.
METHODSAfter chronic heart failure was induced by ligation of the left anterior descending artery in rabbits, the animals were treated with losartan. At 8 weeks after ligation, left ventricular function, hemodynamic parameters, and SERCA2, RyR2, PLB mRNA expressions were observed.
RESULTSCompared with the control group (group C), LVEDP in the infarcted group (group I) increased (P < 0.01), while +dp/dt(max) and -dp/dt(max) decreased significantly (P < 0.01). LVEDP was lower but +dp/dt(max) and -dp/dt(max) significantly higher in the losartan treated group (group L) than those in group I (P < 0.05). SERCA2, RyR2, and PLB mRNA expressions in group I were remarkably lower than those in group L (P < 0.01) and group C (P < 0.01), respectively.
CONCLUSIONLosartan can improve cardiac function, probably owing to its upregulating mRNA expressions of myocardial sarcoplasmic reticulum Ca(2+) handling proteins (RyR2, SERCA2 and PLB) in the prevention of heart failure.
