Objective:To summarize the perioperative nutrition management,improve the successful rate in liver transplantation patients and reduce the complications after operation.Methods:A retrospective analysis of the perioperative nutrition treatment was made in 71 cases with liver transplantation.The principle of enteral nutrition before operation was appropriate energy,protein and rich vitamin,and the branched-chain amino acid(BCAA) and glutamine(Gln) were supplied.Intravenous nutrition,early enteral nutrition and total enteral nutrition support were applied during the postoperation period.Results: Except 5 cases that died from respiratory failure and 2 died from hemorrhagic shock respectively,other 64 cases recovered gradually in liver function,and their nutrition indices were enhanced significantly.Conclusion:The perioperative nutrition management is very necessary for liver transplantation patients,and the appropriate nutrition support is helpful to rehabilitate the function of graft organ and the nutritional status of the recipients as possible as early.

Objective:To explore the regulatory mechanism of α-synuclein in the degradation of autophagy-lysosome pathway(ALP) in Parkinson disease(PD) model cells after interference or overexpression of dynein heavy chain(Dynhc) gene.Methods:SH-SY5Y cells were divided into control group, PD group, Dynhc interference group, Dynhc overexpression group, and Dynhc interference+ rapamycin group according to experimental requirements.Using Western blot to detect Dynhc, α-synuclein, microtubule-associated protein l light chain 3 (LC3), lysosome-associated membrane protein 2 (LAMP2), tubulin, dynein activator protein p150, and kinesin KIF5B.Flow cytometry was used to detect the level of cell apoptosis.Immunoconfocal microscopy was used to observe the structure of tubulin and the co-localization of LC3 and LAMP.SPSS 23.0 software was used for statistical analysis.One-way ANOVA was used for inter group comparisons, and further pairwise comparisons were conducted by LSD- t test. Results:There were statistically significant differences in the expression of α-synuclein, autophagy-related proteins, microtubules, and microtubule-related proteins among cells in the 5 groups(all P<0.001). The protein expression levels of Dynhc, α-synuclein, LC3, LAMP2, p150, and KIF5B in the PD group were higher than those in the control group (all P<0.05). The protein levels of Dynhc, LAMP2, tubulin and p150 in the Dynhc interference group were lower than those in the PD group (all P<0.05), while the protein levels of α-synuclein, LC3 and KIF5B were higher than those in the PD group (all P<0.05). The protein levels of α-synuclein, LC3, and KIF5B in the Dynhc overexpression group were lower than those in the PD group (all P<0.05), while the protein levels of Dynhc, LAMP2 and p150 were higher than those in the PD group (all P<0.05). The protein level of LC3 in the Dynhc interference+ rapamycin group was higher than that in the Dynhc interference group ( P<0.05). There were no statistically significant differences in the protein levels of Dynhc, α-synuclein, LAMP2, microtubule protein, p150 and KIF5B compared to the Dynhc interference group (all P>0.05). Compared with the control group, the cell apoptosis rate in PD group increased((12.77±1.66)%, (7.64±1.45)%), the microtubule morphology remained unchanged, and autophagosomes fused more with lysosomes. Compared with the PD group, the cell apoptosis rate of Dynhc overexpression group decreased, and there was no significant change in microtubule structure, and there was more fusion between autophagosomes and lysosomes.Compared with the PD group, the cell apoptosis rat of Dynhc interference group increased((18.45±1.91)%), and the microtubule morphology was sparse, and there was less fusion between autophagosomes and lysosomes. Compared with the PD group, the Dynhc overexpression group showed a decrease in cell apoptosis rate ((9.95±1.56)%), no significant changes in microtubule structure, and more fusion between autophagosomes and lysosomes.Compared with the Dynhc interference group, the Dynhc interference+ rapamycin group showed no significant changes in cell apoptosis rate ((19.05±2.46)%), microtubule morphology, and fusion of autophagosomes and lysosomes. Conclusion:Dynhc can reduce cell apoptosis by enhancing cell ALP function, increasing the degradation of α-synuclein and maintaining of microtubule structure integrity.

OBJECTIVE: To summarize the genetic characteristics of 671 Chinese pedigrees affected with Duchenne/Becker muscular dystrophy (DMD/BMD). METHODS: Clinical data of the pedigrees were collected. Multiplex PCR, multiple ligation dependent probe amplification (MLPA), next generation sequencing (NGS), Sanger sequencing and long read sequencing were used to detect the variant of DMD gene in the probands and their mothers, and prenatal diagnosis was provided for high risk pregnant women. RESULTS: Among 178 pedigrees analyzed by multiplex PCR, 44 variants of the DMD gene were detected, with the genetic diagnosis attained in 110 pedigrees. Among 493 pedigrees analyzed by MLPA in combination with NGS or Sanger sequencing, 294 pathogenic/possible pathogenic variants were identified, among which 45 were unreported previously, and the genetic diagnosis attained in 484 pedigrees. Structural variants of the DMD gene were identified in two pedigrees by long-read sequencing. Among 444 probands, 341 have inherited the DMD gene variant from their mothers (76.8%). Among 390 women with a high-risk, 339 have opted to have natural pregnancy and 51 chose preimplantation genetic testing for monogenetic disease (PGT-M). The detection rate of neonatal patients and carriers following natural pregnancy was significantly higher than that for PGT-M. CONCLUSION Combined application of MLPA, NGS, Sanger sequencing and long-read sequencing is an effective strategy to detect DMD/BMD. PGT-M can effectively reduce the risk of fetuses. Above finding has expanded the spectrum of DMD gene variants and provided a basis for reproductive intervention for pregnancies with a high risk for DMD/BMD.
