Compared with traditional therapies for chronic liver disease （CLD）， Bifidobacterium has the characteristics of multi-target intervention， high biosafety， and good host compatibility and provides new strategies for intervention of CLD progression in terms of microecological regulation. Various studies have shown that Bifidobacterium regulates liver homeostasis and exerts a therapeutic effect on CLD by regulating intestinal flora， maintaining antioxidation， promoting energy consumption， alleviating inflammation， improving glycolipid metabolism， and exerting an antitumor effect. This article systematically reviews the studies on Bifidobacterium in the treatment of CLD in China and globally， explores their different mechanisms， and elaborates on the interaction between related signaling pathways （such as the nuclear factor erythroid 2-related factor 2 signaling pathway and the adenosine monophosphate-activated protein kinase signaling pathway） and the liver， in order to provide a basis for probiotic intervention in liver pathology， as well as new ideas for the comprehensive treatment of CLD.

The paper introduces 5 books written by WANG Mengying, including Suixiju Chongding Huoluan Lun, Guiyan Lu, Wenre Jingwei, Wang Mengying Yi'an and Suixiju Yinshipu; and analyzes the ideas of diagnosis and treatment of cholera and the academic thoughts in treatment with acupuncture-moxibustion therapy. In pathogenesis, cholera is classified into cold and heat types. Cholera of heat type roots on qi and blood. If the pathogenic factors are mild and located shallowly, the sneezing method, followed by scraping method, is adopted to open meridians and collaterals, as well as the qi level, so as to eliminate pathogens. When the pathogens go deeply, the bloodletting technique is used to clean the toxic heat in blood level and reduce the reversed qi. For cholera of cold type, warm ironing moxibustion is delivered to promote qi circulation and disperse cold, and improve qi movement. If spasm and syncope occur in cholera, no matter of cold or heat identification, the emergent measure is operated with the external application of pungent, warm and salty herbal plaster at Yongquan (KI1). When the pathogens are almost eliminated, the herbal medicines are combined to treat the symptoms and remove the causative factors of the disease.

ObjectiveTo investigate the role and possible mechanism of action of rhubarb decoction （RD） retention enema in improving inflammatory damage of brain tissue in a rat model of mild hepatic encephalopathy （MHE）. MethodsA total of 60 male Sprague-Dawley rats were divided into blank group （CON group with 6 rats） and chronic liver cirrhosis modeling group with 54 rats using the complete randomization method. After 12 weeks， 40 rats with successful modeling which were confirmed to meet the requirements for MHE model by the Morris water maze test were randomly divided into model group （MOD group）， lactulose group （LT group）， low-dose RD group （RD1 group）， middle-dose RD group （RD2 group）， and high-dose RD group （RD3 group）， with 8 rats in each group. The rats in the CON group and the MOD group were given retention enema with 2 mL of normal saline once a day； the rats in the LT group were given retention enema with 2 mL of lactulose at a dose of 22.5% once a day； the rats in the RD1， RD2， and RD3 groups were given retention enema with 2 mL RD at a dose of 2.5， 5.0， and 7.5 g/kg， respectively， once a day. After 10 days of treatment， the Morris water maze test was performed to analyze the spatial learning and memory abilities of rats. The rats were analyzed from the following aspects： behavioral status； the serum levels of alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α） and the level of blood ammonia； pathological changes of liver tissue and brain tissue； the mRNA and protein expression levels of phosphatidylinositol 3-kinase （PI3K）， protein kinase B （AKT）， and mammalian target of rapamycin （mTOR） in brain tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the MOD group， the RD1， RD2， and RD3 groups had a significantly shorter escape latency （all P<0.01）， significant reductions in the levels of ALT， AST， IL-1β， IL-6， TNF-α， and blood ammonia （all P<0.05）， significant alleviation of the degeneration， necrosis， and inflammation of hepatocytes and brain cells， and significant reductions in the mRNA and protein expression levels of PI3K， AKT， and mTOR in brain tissue （all P<0.05）， and the RD3 group had a better treatment outcome than the RD1 and RD2 groups. ConclusionRetention enema with RD can improve cognitive function and inflammatory damage of brain tissue in MHE rats， possibly by regulating the PI3K/AKT/mTOR signaling pathway.

Objective:To explore the safety and efficacy of EAC [etoposide+ cytarabine+ cyclophosphamide (CTX)] mobilization scheme for mobilizing stem cells in patients with lymphoma undergoing autologous hematopoietic stem cell transplantation (ASCT).Methods:A total of 36 patients with lymphoma who had collected peripheral blood stem cells through EAC or CTX+ granulocyte colony stimulating factor (G-CSF) mobilization scheme in Cancer Hospital & Shenzhen Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College from June 2018 to March 2020 were retrospectively analyzed. Among them, 16 patients used EAC mobilization (EAC group), and 20 patients used CTX (CTX group). When white blood cells≤1.0×10 9/L, G-CSF (10 μg/kg per day) was given subcutaneously in two doses. The changes of hematology indexes, the number of collected cells, adverse reactions during mobilization collection and hematopoietic reconstitution after ASCT were observed. Results:The peripheral blood stem cells were collected on 5 d (3-8 d) after EAC+ G-CSF mobilization and 7 d (4-12 d) after CTX+ G-CSF mobilization. The success rates of collection in the EAC group and CTX group were 100% (16/16) and 75.0% (15/20) respectively, the high-quality collection rates were 87.5% (14/16) and 25.0% (5/20) respectively, and there were statistically significant differences ( P=0.041; P<0.001). The median of CD34 + cells of the two groups was 13.67×10 6/kg and 3.45×10 6/kg respectively, the median of mononuclear cells was 7.16×10 8/kg and 5.09×10 8/kg respectively, the median of CD34 + cells/mononuclear cells was 1.44% and 0.67% respectively, and there were statistically significant differences ( Z=-4.219, P<0.001; Z=-2.118, P=0.034; Z=-3.104, P=0.002). In the EAC group and CTX group, the incidences of grade 3 and above granulocytopenia were 100% (16/16) and 90.0% (18/20) respectively, the incidences of grade 3 and above hemoglobin reduction were 43.8% (7/16) and 25.0% (5/20) respectively, the incidences of grade 3 and above thrombocytopenia were 87.5% (14/16) and 65.0% (13/20) respectively, and there were no statistically significant differences ( P=0.492; P=0.298; P=0.245). There were no significant differences in the incidences of infection, adverse reactions of digestive system or other adverse reactions between the two groups (all P>0.05). All patients accepted improved Bucy scheme before ASCT. The median implantation time of neutrophils and platelets was 9.0 d and 10.5 d in the EAC group, which was 12.0 d and 13.5 d in the CTX group, and there were statistically significant differences ( Z=-4.698, P<0.001; Z=-3.757, P<0.001). Conclusion:EAC mobilization scheme can significantly increase the number of hematopoietic stem cell. This scheme has a high success rate of high-quality collection and the adverse reactions are within the controllable range. It provides a high-quality mobilization scheme for hematopoietic stem cell mobilization and collection, which is worthy of clinical promotion and application.

Objective: To investigate the value of ultrasound in the localization of peripherally inserted central catheter (PICC) in neonates. Methods: A retrospective analysis of the PICC catheterization was conducted at Department of Neonatology, Beijing Chaoyang District Maternal and Child Healthcare Hospital from June 2017 to December 2018.The ultrasound monitoring was performed immediately after PICC catheterization.The probe was placed into the midline position of the lower xiphoid or the subclavian parasternal line for scanning, and it would be the PICC if a high-echo " equal sign" was observed by ultrasound.It was believed that the PICC was successfully placed when ultrasound detected that the PICC tip was located in the junction of inferior vena cava or superior vena cava in the right atrium. Results: (1)Among 112 infants with PICC catheterization, 103 cases (92.0%) were accurately placed, 9 cases (8.0%) were not placed in the ideal site, among them, 2 cases were too deep, 4 cases were too shallow and 3 cases were catheter heterotopia.The tip position was accurate after the readjustment under ultrasound monitoring in those patients whose the first ultrasound showed the tip position was not ideal.(2)The PICC indwelling time was as short as 2 days (removed due to severe arrhythmia) and as long as 56 days with an average of (15.1±10.7) days.(3)The catheter-related complications occurred in 3 cases with an incidence of 2.7%. Conclusions Using ultrasound to determine the PICC tips position is accurate and reliable, which is worthy of extensive application in the neonatal wards.
