ObjectiveTo evaluate the one-year follow-up of the therapeutic efficacy of human umbilical cord derived-mesenchymal stem cell (UC-MSC) transplantations in decompensated liver cirrhosis patients with ascites.MethodsFifty-four liver cirrhosis patients with ascites in Research Center for Biological Therapy in 302 Military Hospital were divided into treatment group (n=38) and control group (n=16) in a prospective controlled single-blinded trial.UC-MSC (0.5-1.0) × 106/kg and saline were intravenously transplanted into patients monthly for 3 times in treatment group and control group,respectively.The liver function,hepatitis B virus (HBV) DNA level,ascites and the model for end-stage liver disease(MELD)scores at different time points were compared between two groups.The comparison between groups was done by Mann-Whitney U test,and the data before and after transplantations were compared by Wilcoxon signed rank sum test.ResultsThere were no significant differences of alanine transaminase (ALT),total bilirubin (TBil),cholinesterase (CHE),HBV DNA positive rate and MELD scores at different time points between two groups (P>0.05).However, the albumin ( A1b)level was significantly increased after 36 weeks of UC-MSC transplantation in treatment group, which were (28.47±4.45)g/L at week 0 and ( 34.82±4.50)g/L at week 48 (P=0.046). Meanwhile, the ascites reduced markedly in treatment group with (46.6 ±30.6) mm at week 0 and (6.6±13.6) mm at week 48,which were significantly different from control group at the end of follow-up (P =0.037). Conclusion UC-MSC transplantations may help to increase A1b level and reduce ascites in patients with decompensated liver cirrhosis.

OBJECTIVE:
To explore the genetic basis for a child with infantile liver failure syndrome type 2 (ILFS type 2).
METHODS:
Clinical features of the child were analyzed. Next generation sequencing was also carried out for him.
RESULTS:
The child was found to harbor compound heterozygous variants of the NBAS gene, which included a novel nonsense c.2746A>T (p.R916X, 1456) variant in exon 24 and a missense c.3596G>A (p.C1199Y) mutation in exon 31, which has been associated with ILFS type 2. The two variants were respectively inherited from his father and mother.
CONCLUSION
The compound heterozygous variants of c.3596G>A and c.2746A>T of the NBAS gene probably underlay the ILFS type 2 in this child.

Objective:To investigate the etiology, prognosis and prognostic factors of pediatric acute liver failure(PALF), in order to provide the basis for clinical treatment of PALF.Methods:The clinical data of children with PALF hospitalized at Hunan Children′s Hospital from May 2008 to May 2018 were collected, and the causes and prognosis were analyzed.According to the prognosis, the patients were divided into the death group and the survival group, whose biochemical indexes were then compared.After that, the statistical analysis of different data were carried out by using t-test, Wilcoxon test and χ2 test separately. Results:In 120 PALF cases, there were 68 males and 52 females, and there were 36 infants, 34 toddlers, 22 preschoolers and 28 school-age children.Twenty cases (16.7%) were caused by sepsis, 19 cases (15.8%) by genetic metabolic diseases, 18 cases (15.0%) by poisoning, 12 cases (10.0%) by viral infection, 6 cases (5.0%) by drugs, 1 case (0.8%) by bile polyp, and 1 case (0.8%) by tumor disease.Besides, the etiology of 43 cases (35.9%) was unknown.Among the cases with known etiologies, genetic metabolic and infectious diseases were the main cause of disease in infants, toddler patients were mostly caused by infectious diseases and drug/toxicants, and drug/toxicants and hereditary metabolic diseases were the dominant cause of disease in school-age children and preschoolers.Mortality rate of children with PALF was 50.0%.Among them, the mortality of Epstein-Barr virus-associated hemophagocytic syndrome, sepsis, Citrin deficiency and Tyrosinemia was higher than that of other diseases.Compared with the survival group, the total bilirubin (TB)[159.00(73.05, 274.00) μmol/L vs.62.75(2.65, 221.75)μmol/L], direct bilirubin(DB)[83.00(41.43, 160.00) μmol/L vs.38.74(10.98, 128.75) μmol/L], prothrombin time (PT)[39.60(24.93, 62.60) s vs.24.65(21.43, 29.83) s], international standardized ratio (INR)[3.40(2.30, 6.74) vs.2.09(1.85, 2.84)], and blood ammonia (NH 3) levels [109.50(85.25, 149.75) μmol/L vs.80.00(60.25, 102.75) μmol/L] in the death group were significantly increased, and the diffe-rences were statistically significant(all P<0.05); while the levels of albumin[(28.72±5.88) g/L vs.(33.69±4.96) g/L], alanine aminotransferase (ALT) [586.50(223.25, 1 082.00) U/L vs.1 434.00(615.00, 3 334.50) U/L]and aspartate aminotransferase (AST) [827.50(545.00, 2 024.00) U/L vs.1 663.50(821.00, 4 886.75) U/L]in the death group were significantly decreased, and the differences were statistically significant(all P<0.05). However, the blood glucose and cholesterol levels in both groups had no statistically significant difference. Conclusion:The mortality of children with PALF is high, and different age groups have different etiologies.The increase of TB, DB, PT, INR, NH3 and the ratio of hepatic encephalopathy, and the decrease of albumin, AST and ALT suggest poor prognosis.

Objective:
To observe the effect of curcumin on myocardial mitochondrial related gene (mtATP6), high mobility group box 1(HMGB1) mRNA expression and plasma HMGB1 level in rats with sepsis, and to explore a new strategy for protection of myocardial injury in sepsis.
Methods:
A rat sepsis model was established by cecal ligation and puncture (CLP). Thirty male Sprague-Dawley rats were randomly (random number) divided into the sham operation group (sham group), sepsis group (CLP group), and curcumin intervention group (Cur group), with 10 rats in each group. Rats in the Cur group were treated with curcumin by intraperitoneal injection at 100 mg/kg, and normal saline was injected into rats in the sham and CLP groups. Five rats were randomly (random number) sacrificed at 6 h and 24 h after modeling. The pathological changes of myocardial tissue were observed under light microscope. The levels of CK and CK-MB in serum were detected. The HMGB1 level in plasma was detected by ELISA. Real-time PCR was used to detect the expression of HMGB1 mRNA and mtATP6 in myocardial tissue. One-way ANOVA were performed in multigroup mean comparison, LSD-

OBJECTIVE: To explore the mechanism of ubiquitin-proteasome pathway(UPP) in the degradation of hyperphosphorylated tau protein in aluminum-induced mouse neuroblastoma N2 a cells. METHODS: N2 a cells in logarithmic growth period were randomly divided into control group and MG132 group. Cells in control group were exposed to concentrations of 0 or 1 mmol/L aluminum chloride for 24 hours. Cells in MG132 group were pretreated with MG132 at a concentration of 5 μmol/L for 6 hours, then exposed to concentrations of 0 or 1 mmol/L aluminum chloride for 24 hours. After exposure, the cells were collected. Western blotting was used to detect the relative expression of tau-5, P-tau181, P-tau231, P-tau262, P-tau396, heat shock protein 70(Hsp70) and carboxyl terminus of the Hsp70-interacting protein(CHIP). The ubiquitin relative expression was detected by enzyme-linked immunosorbent assay. RESULTS: The results of factorial analysis showed that the relative expression of tau-5, P-tau231, P-tau262, P-tau396, CHIP, Hsp70 and ubiquitin in N2 a cells were statistically significant in the main effect and interaction effect of aluminum chloride and MG132 treatment(P<0.05). Both in the control group and MG132 group, the relative expression of tau-5, P-tau231, P-tau262, P-tau396, CHIP, Hsp70 and ubiquitin in N2 a cells exposed to 1 mmol/L aluminum chloride increased(P<0.05) when compared with the N2 a cells without exposed to aluminum chloride. No matter aluminum chloride exposed or not, the relative expression of tau-5, P-tau231, P-tau262, P-tau396, CHIP, Hsp70 and ubiquitin in N2 a cells of MG132 group was higher than that of control group(P<0.05). CONCLUSION: UPP is involved in the regulation of hyperphosphorylated tau protein by proteasome degradation in aluminum-induced N2 a cells. UPP mainly regulates P-tau231, P-tau262, and P-tau396 sites. CHIP and Hsp70 played an important role in the UPP pathway.
