The common marmoset (Callithrix jacchus) is a species of the genus Callithrix in the primate family Callitrichidae. Common marmosets are an important scientific research resource for the study of neuroscience, medicine, and pharmacy. The feeding and breeding of common marmosets provide important support for scientific research. At present, common marmoset resources in China are at a critical stage of development. This paper takes the Center for Excellence in Brain Science and Intelligence Technology of the Chinese Academy of Sciences (hereafter referred to as CEBSIT) as an example to discuss the experience of common marmoset feeding, breeding and genetic management. In terms of breeding environment and facilities, on the basis of the national standard, more stringent environmental parameter standards are implemented for environmental temperature, relative humidity, the number of air exchanges, and the average concentration of sedimentation bacteria. Two kinds of cages for common marmoset breeding and experimentation are designed. According to the differences in facility conditions and staffing, a cleaning and maintenance method combining "dry rearing" and "wet rearing" is introduced. In terms of feeding management, in order to meet the high nutritional needs of common marmosets, CEBSIT prepares special formulated diets, and introduces the transition method of common marmosets from diets mixed with formulated rations and pellets to exclusive commercial diets, and strictly regulates the operation procedures of formulated diets for common marmosets, and has accumulated a series of methods for preventing nutritional and metabolic diseases in common marmosets. In terms of animal health management, the health of common marmosets is ensured through measures such as regular quarantine, isolation and treatment, and epidemic prevention, and the health inspection process of common marmosets is described in detail, and hierarchical and classified management is carried out according to the physical condition of common marmosets. This paper also briefly describes the treatment of diarrhea and pneumonia that are common in common marmosets. In terms of breeding management, it covers the selection of breeding common marmosets, combining pairs of common marmosets into the same cage for breeding, group splitting and hand-rearing of infant common marmosets, and introduces the method of reintroducing hand-reared infant common marmosets to parental care from the perspective of animal welfare. In terms of genetic management, the common marmoset population in CEBSIT is maintained as a closed colony and follows a non-inbreeding method. CEBSIT has developed an inbreeding screening system to check pedigree information before pairing to avoid inbreeding. Under conditions without introducing new individuals from outside, CEBSIT has continuously bred the colony for 5 generations while maintaining genetic heterozygosity. This paper only discusses the feeding, breeding and genetic management of the common marmoset and aims to provide a useful reference for other institutions engaged in common marmoset breeding.

Objective:To explore the relationship between serum thymic stromal lymphopoietin (TSLP) levels and the occurrence of pruritus as well as interstitial lung diseases (ILD) in patients with dermatomyositis (DM) or clinically amyopathic dermatomyositis (CADM) .Methods:A retrospective analysis was conducted on the clinical data from 61 diagnosed DM/CADM patients at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine between February 2019 and March 2022. Thirty-five age- and sex-matched healthy individuals were included as controls. Serum TSLP and anti-melanoma differentiation-associated gene 5 (MDA5) antibody levels were measured using enzyme-linked immunosorbent assay (ELISA) . A multiplexed flow cytometry assay was performed to detect the serum levels of 12 cytokines, including interferon (IFN) -α2, IFN-γ, interleukin (IL) -4, IL-5, etc. Pruritus severity in DM/CADM patients was assessed using the visual analog scale (VAS) . Relationships of serum TSLP levels with skin lesions, inflammatory markers, and the severity of ILD were analyzed using GraphPad Prism 8.0.1 and R (version 4.3.2) software.Results:Among the 61 patients with DM/CADM, 18 were males (13 with DM and 5 with CADM) and 43 were females (30 with DM and 13 with CADM) , with ages of 53.08 ± 14.97 years and disease duration of 6.27 ± 4.27 months. No significant differences were observed in sex or age between the DM/CADM group and the healthy control group (both P > 0.05) . Of the 61 patients, 15 (24.59%) were positive for anti-MDA5 antibodies, and 31 (51.67%) had ILD, including 11 with acute/subacute interstitial pneumonia (A/SIP) . The pruritus VAS score ( M[ Q1, Q3]) among the 61 patients was 3 (0, 6) points; 20 patients (32.79%) reported no pruritus, while 11 (18.32%) , 17 (27.87%) , and 13 (21.31%) experienced mild, moderate, and severe pruritus, respectively. Serum TSLP levels were significantly higher in the DM/CADM patients than in the healthy controls (91.0 [34.6, 273.0] vs. 25.0 [0.0, 83.5] pg/ml, Z = 1 502.50, P < 0.001]. The TSLP levels were significantly positively correlated with serum levels of alanine aminotransferase (ALT) , lactate dehydrogenase, C-reactive protein, erythrocyte sedimentation rate and ferritin, and significantly negatively correlated with pruritus VAS scores, eosinophil percentages, and eosinophil counts (all P < 0.05) . Serum TSLP levels were significantly higher in the anti-MDA5 antibody-positive patients than in the anti-MDA5 antibody-negative patients (273.0 [103.8, 2 576.0] pg/ml vs. 67.4 [16.9, 218.7] pg/ml, P = 0.002) , as well as in the patients with A/SIP than in those without A/SIP (390.0 [168.2, 2 869.6] vs. 67.5 [21.8, 235.9] pg/ml, P < 0.001) . ROC analysis showed that the combined detection of serum TSLP levels and anti-MDA5 antibodies had a higher predictive value for A/SIP in DM/CADM patients (AUC = 0.922) than either the detection of anti-MDA5 antibodies (AUC = 0.831) or TSLP (AUC = 0.824) alone did. Conclusions:Serum TSLP levels were significantly higher in patients with DM/CADM than in healthy controls, with particularly higher levels observed in anti-MDA5 antibody-positive patients and patients with coexisting A/SIP, and were correlated with several indicators of disease activity. The combination of serum TSLP levels and anti-MDA5 antibodies provided greater predictive value for A/SIP than either of them alone did.

Objective:To screen key genes that co-regulate immune and mitochondrial energy metabolism through bioinformatics methods and to investigate the relationship between the key genes and immune infiltration.Methods:A total of 671 glioma samples (the tumor group) and 5 non-tumor brain tissue samples (the control group) were collected from the Cancer Genome Atlas (TCGA) database on November 13, 2023. Through a comprehensive search of the GeneCards database and immune-related genes (IRG) and mitochondrial energy metabolism-related genes (MEMRG) in previous published literatures, 76 IRG and MEMRG (IR & MEMRG) were obtained by taking the intersection of IRG and MEMRG after merging and deduplicating. The limma package in R software was used to screen the differentially expressed genes (DEG) between the tumor group and the control group. Then, immune-related & mitochondrial energy metabolism-related differentially expressed genes (IR&MEMRDEG) were obtained by intersecting with IR & MEMRG. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were conducted on the IR&MEMRDEG through the clusterProfiler package in R software. The STRINGv12.0 online database (https://cn.string-db.org/) was employed to construct a protein interaction network based on IR&MEMRDEG and to identify the top 5 key core genes. Single-sample gene-set enrichment analysis (ssGSEA) was used to determine the relative abundance of immune cell infiltration in all samples, and the immune cell infiltration matrices for both the tumor and the control groups were acquired. The expression differences in infiltration abundance of the immune cells in the tumor group and the control group were analyzing by using the ggplot2 package in R software. The heat map was drawn by utilizing the R software pheatmap package to show self-correlation of immune cells. The correlation between the top 5 key genes in the protein interaction network and immune cells was calculated by using the Spearman algorithm and the R software ggplot2 package.Results:A total of 3 623 DEGs were identified from the TCGA database in both groups, including 1 711 up-regulated genes and 1 912 down-regulated genes. After taking the intersection of DEG and IR&MEMRG, 11 IR&MEMRDEG were obtained including EIF4EBP1, TP53, IDH1, PRCKZ, CD200, GPI, PGM2, PKLR, AK2, ATP4A, and ALDH3B1. GO enrichment analysis results showed that 11 IR&MEMRDEG were mainly enriched in ADP metabolic process, ATP metabolic process, purine nucleoside diphosphate metabolic process, purine ribonucleoside diphosphate metabolic process, and ribonucleoside diphosphate metabolic process at the biological level; in the fibronectin-1 rich granule, secretory granule lumen, cytoplasmic vesiclelumen, vesiclelumen, and nuclear matrix at the cellular component level; in magnesium ion binding, potassium ion binding, and alkali metal ion binding at the molecular functional level. The KEGG enrichment analysis results showed that 11 IR&MEMRDEGs were mainly enriched in glycolysis/gluconeogenesis, carbon metabolism, insulin signaling pathway, pentose phosphate pathway, starch and sucrose metabolism signaling pathways. The protein interaction network analysis from the STRING database revealed that 5 highest scoring core proteins were identified, namely EIF4EBP1, TP53, IDH1, PRKCZ, and AK2.The immune infiltration abundances of 28 immune cells were calculated by using the ssGSEA algorithm. The infiltration abundance of 15 immune cells in the tumor group was higher than that in the control group, and the differences were statistically significant (all P < 0.05). The findings from the immune infiltration analysis indicated a positive correlation among 15 types of immune cells, in which there was a strongest correlation between effector memory CD8 + T cell and myeloid derived suppressor cells. EIF4EBP1, TP53, IDH1, and AK2 exhibited a positive correlation with a large number of immune cells (all P < 0.05), whereas PRKCZ demonstrated a negative correlation with more immune cells (all P < 0.05). Conclusions:PRKCZ, AK2, and EIF4EBP1 have the potential to be the new targets of immunotherapy for gliomas.

Objective:To investigate the application value of laparoscopic-assisted total liver transplantation.Methods:The retrospective and descriptive study was conducted. The clinical data of 9 pairs of donors and recipients who underwent laparoscopic-assisted total liver transplanta-tion in People′s Hospital of Guangxi Zhuang Autonomous Region from January to April 2024 were collected. Of the donors, there were 8 males and 1 female, aged (39±18)years and with body mass index (BMI) of (20±4)kg/m 2. Of the recipients, there were 7 males and 2 females, aged (41±13)years and with BMI of (24±4)kg/m 2. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers. Results:(1) Surgical conditions. Of the 9 recipients, 7 recipients underwent laparoscopic-assisted total liver transplantation successfully, 1 recipient with severe portal hypertension converted to open surgery with reverse L-shaped incision due to the hemorrhage during the dissection of the first hepatic portal after completing liver mobilization under laparoscopy, and 1 recipient underwent trans-umbilical extension incision through the middle of the epigastric region due to the limited space for operation in the implantation of the donor liver. The total operation time for 7 recipients who successfully underwent laparoscopic-assisted total liver transplantation was (648±31)minutes, with a time of anhepatic phase of (57±5)minutes, the volume of intraoperative blood loss of (1 322±627)mL, the donor liver mass of (1 195±232)g, and the ratio of donor liver mass to recipient body mass of 1.86%±0.42%. The operation time for laparoscopic liver dissection and porta hepatis dissection in 8 recipients during surgery was (212±35)minutes. (2) Postoperative conditions. All 9 recipients recovered smoothly after surgery, without any vascular or biliary related complications, and the surgical incision recovered well. The duration of postoperative hospital stay of 7 recipients who successfully underwent laparoscopic-assisted total liver transplantation was (14.2±2.0)days. (3) Follow-up. All 9 recipients were followed up for 3 months after surgery. During the follow-up period, there was no vascular or bile duct related complication.Conclusion:Laparoscopic-assisted total liver transplantation can be applied to recipients who meet surgical conditions and achieve good short-term clinical efficacy.

Background: Mechanical ventilation, particularly one-lung ventilation (OLV), can cause pulmonary dysfunction. This meta-analysis assessed the effects of dexmedetomidine on the pulmonary function of patients receiving OLV. Methods: The Embase, PubMed, MEDLINE, Cochrane Library, ClinicalTrials.gov, and Chinese Clinical Trial Registry databases were systematically searched. The primary outcome was oxygenation index (OI). Other outcomes including the incidence of postoperative complications were assessed. Results: Fourteen randomized controlled trials involving 845 patients were included in this meta-analysis. Dexmedetomidine improved the OI at 30 (mean difference [MD]: 40.49, 95% CI [10.21, 70.78]), 60 (MD: 60.86, 95% CI [35.81, 85.92]), and 90 min (MD: 55, 95% CI [34.89, 75.11]) after OLV and after surgery (MD: 28.98, 95% CI [17.94, 40.0]) and improved lung compliance 90 min after OLV (MD: 3.62, 95% CI [1.7, 5.53]). Additionally, dexmedetomidine reduced the incidence of postoperative pulmonary complications (odds ratio: 0.44, 95% CI [0.24, 0.82]) and length of hospital stay (MD: −0.99, 95% CI [−1.25, −0.73]); decreased tumor necrosis factor-α, interleukin (IL)-6, IL-8, and malondialdehyde levels; and increased superoxide dismutase levels. However, only the results for the OI and IL-6 levels were confirmed by the sensitivity and trial sequential analyses. Conclusions Dexmedetomidine improves oxygenation in patients receiving OLV and may additionally decrease the incidence of postoperative pulmonary complications and shorten the length of hospital stay, which may be related to associated improvements in lung compliance, anti-inflammatory effects, and regulation of oxidative stress reactions. However, robust evidence is required to confirm these conclusions.
