Objective: To investigate the clinical efficacy of liver transplantation in the treatment of acute liver in children with NBAS gene deficiency disease and their outcome. Methods: This retrospective study enrolled children with NBAS gene deficiency who were admitted to the Children's Hospital of Fudan University for liver transplantation from January 2013 to June 2022. The clinical data were collected and analyzed. Medical literature published before June 2022 was searched with the keywords of "NBAS" "neuroblastoma amplified sequence recurrent" "acute liver failure" "SOPH syndrome" "short stature with optic nerve atrophy" "Pelger-Huët anomaly" in PubMed, China National Knowledge Infrastructure and Wanfang database. Results: Liver transplantation was performed in 3 patients (2 males and 1 female) with NBAS deficiency. All patients presented with fever-triggered recurrent acute liver failure. The genetic detection found compound heterozygous NBAS gene pathogenic variants in them. The total episodes of acute liver failure before liver transplantation were 11, 2, and 4 respectively, and the age at liver transplantation was 3.5, 2.3, and 2.0 years respectively. During liver transplantation, patient 1 was in the convalescent phase of acute liver failure, patient 2 was in the acute phase, presenting with hepatic encephalopathy (grade V) and respiratory failure, and patient 3 was considered to be in the acute phase. After liver transplantation, patient 1 recovered normal liver function within 1 month and had no liver transplantation-related complications. Patient 2 had secondary epilepsy, intellectual disability, movement disorder, and transiently elevated transaminases. Patient 3 died of severe infection within 1 month. There was no literature in Chinese, 6 in English, 8 NBAS-deficient patients who were treated with liver transplantation. Total 11 patients presented with fever-triggered recurrent acute liver failure. Their age at liver transplantation ranged from 0.9 to 5.0 years. Postoperative complications occurred in 3 patients. Until the last visit, they were followed up for 0.7 to 14.0 years. Total 2 patients died and the 9 surviving patients did not develop acute liver failure. Conclusions: Liver transplantation is effective for the treatment of acute liver failure associated with NBAS gene disease. However, postoperative complications of liver transplantation may occur. The timing of liver transplantation still needs further research.

OBJECTIVES: To study the effect of breastfeeding on immune function in infants with human cytomegalovirus (HCMV) infection. METHODS: A retrospective analysis was performed on the medical data of 135 infants with HCMV infection who were admitted to Children's Hospital Affiliated to Zhengzhou University from January 2021 to May 2022, and all these infants received breastfeeding. According to the results of breast milk HCMV-DNA testing, the infants were divided into two groups: breast milk HCMV positive (n=78) and breast milk HCMV negative (n=57). According to the median breast milk HCMV-DNA load, the infants in the breast milk HCMV positive group were further divided into two subgroups: high viral load and low viral load (n=39 each). Related indicators were compared between the breast milk positive and negative HCMV groups and between the breast milk high viral load and low viral load subgroups, including the percentages of peripheral blood lymphocyte subsets (CD3⁺ T cells, CD3⁺CD4⁺ T cells, CD3⁺CD8⁺ T cells, and CD19⁺ B cells), CD4⁺/CD8⁺ ratio, IgG, IgM, IgA, and urine HCMV-DNA load. RESULTS: There were no significant differences in the percentages of CD3⁺ T cells, CD3⁺CD4⁺ T cells, CD3⁺CD8⁺ T cells, and CD19⁺ B cells, CD4⁺/CD8⁺ ratio, IgG, IgM, IgA, and urine HCMV-DNA load between the breast milk HCMV positive and HCMV negative groups, as well as between the breast milk high viral load and low viral load subgroups (P>0.05). CONCLUSIONS Breastfeeding with HCMV does not affect the immune function of infants with HCMV infection.

This study aimed to evaluate the efficacy of Qi-supplementing and Yin-nourishing Chinese patent medicine in the treatment of early diabetic nephropathy(DN) by network Meta-analysis to explore the Chinese patent medicine with optimal efficacy and provide references for preventing renal deterioration and delaying the progression of early DN. Eight databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, were searched for clinical randomized controlled trial(RCT) of Qi-supplementing and Yin-nourishing Chinese patent medicines in the treatment of early DN. After the literature mee-ting the inclusion criteria was screened, the quality of the literature was evaluated using the Cochrane risk-of-bias tool, and network Meta-analysis was performed using the BUGSnet package in R 4.2.1. Seventy-two research articles with a sample size of 6 344 cases were included, involving eight Chinese patent medicines and seven outcome indicators. The results of the network Meta-analysis showed that(1)in terms of improving urinary albumin excretion rate(UAER), Chinese patent medicines combined with conventional treatment were superior to conventional treatment, and Qiyao Xiaoke Capsules + conventional treatment was optimal.(2)In terms of reducing serum crea-tinine(Scr), Bailing Capsules + conventional treatment had superior efficacy.(3)In terms of reducing 24-hour urine total protein(24hUTP), Shenyan Kangfu Tablets + conventional treatment and Jinshuibao Capsules + conventional treatment had equivalent efficacy, and Shenyan Kangfu Tablets + conventional treatment was superior.(4)In terms of improving fasting blood glucose(FBG), Shenyan Kangfu Tablets + conventional treatment had superior efficacy.(5)In terms of improving total cholesterol(TC), Qiyao Xiaoke Capsules +conventional treatment had superior efficacy.(6)In terms of reducing triglyceride(TG), Bailing Capsules + conventional treatment had superior efficacy.(7)In terms of safety, the occurrence of adverse reactions was reported in seven interventions, but due to the large clinical heterogeneity, the quantitative analysis could not be performed. Overall, Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment were superior to conventional treatment alone in the treatment of early DN. The results showed that Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment had good clinical efficacy, and they could significantly reduce renal function indicators such as UAER, Scr, and 24hUTP, and reduce blood sugar and blood lipid, which can provide evidence-based support for the treatment of early DN. However, due to the differences in the quantity and quality of the included research articles, large-sample, multi-center, high-quality studies are still needed for further verification.

OBJECTIVE To study the possible effects and mechanism of Jinxin oral liquid and its main ingredient baicalin on Re-spiratory syncytial virus(RSV)-induced abnormal cardiolipin metabolism.METHODS BALB/c mice were randomly divided into control group,RSV group and Jinxin oral liquid treatment group.Mice were nasally administrated of RSV suspension to establish RSV infection model at the first 3 days.Then Jinxin oral liquid 27.6 g·kg-1·d-1 was administrated intragastrically for the next 3 days from the afternoon of the third day.Raw264.7 cells were infected by RSV to establish an in vitro infection model and baicalin(100 mg·kg-1·d-1)was given for intervention.The changes of cardiolipin metabolism profiles in mice lung tissue and Raw264.7 cells were detected by chromatography-mass spectrometry.Transcriptional mRNA levels of RSV surface proteins RSV-F and RSV-G,inflammatory cytokines IL-6,IL-1β and Tnf-α,cardiolipin metabolic enzymes Tafazzin(TAZ),Cardiolipin Synthase 1(Crls1),Phospholipid Scramblase 3(PLSCR3)and autophagy-related protein p62 were detected by qPCR.The protein level of p62 was detec-ted by Western blot.Molecular docking was used to detect the binding ability of p62 to CL14 ∶ 0-16 ∶ 1-16 ∶ 1-18 ∶ 2.RESULTS The expression of IL-6,IL-1β,and Tnf-α mRNA increased in RSV-infected mice and cell models(P<0.05,P<0.01,P<0.001).Jinxin oral liquid and baicalin plays a certain restoration effect.The cardiolipin metabolism profile changes after RSV infec-tion,and Jinxin oral liquid and baicalin can play a certain regulatory role.The expression of Crls1 and TAZ mRNA in the lung tissue of mice in the model group was significantly up-regulated(P<0.01),after administration of Jinxin oral liquid,the expression of Crls1 and TAZ mRNA was significantly reduced(P<0.01);the expression of Crls1 mRNA in the cell model group was significantly in-creased(P<0.001),and after baicalin intervention,the expression of Crls1 mRNA was significantly reduced(P<0.000 1).The ex-pression of p62 protein in the lung tissue of RSV-infected mice was significantly reduced(P<0.001),and the expression of p62 pro-tein was significantly increased after administration of Jinxin oral liquid(P<0.01).The p62 protein expression in the Raw264.7 cell model group increased significantly(P<0.05),and the p62 protein level further increased significantly after administration of baicalin(P<0.000 1).Molecular docking results showed that cardiolipin CL14 ∶ 0-16 ∶ 1-16 ∶ 1-18 ∶ 2 can threshold-bind with the UBA structure of p62.CONCLUSION Jinxin oral liquid and baicalin can improve RSV-induced cardiolipin metabolism disorder,regulate mitochondrial function,and thus exert anti-RSV infection effects.
