OBJECTIVE: To explore the clinical features and genetic variant in a child with Cerebral creatine deficiency syndrome (CCDS). METHODS: A child who had presented at the Affiliated Children's Hospital of Fudan University on March 5, 2021 was selected as the study subject. Whole exome sequencing (WES) was carried out for the child, and candidate variant was verified by Sanger sequencing. The level of creatine in the brain was determined by magnetic resonance spectroscopy. RESULTS: The patient, a 1-year-and-10-month male, had presented with developmental delay and epilepsy. Both his mother and grandmother had a history of convulsions. MRS showed reduced cerebral creatine in bilateral basal ganglia and thalamus. The child was found to harbor a hemizygous splicing variant of the SLC6A8 gene, namely c.1767+1_1767+2insA, which may lead to protein truncation. The variant was not found in the public databases. Both his mother and grandmother were heterozygous carriers for the same variant. CONCLUSION The hemizygous c.1767+1_1767+2insA variant of the SLC6A8 gene probably underlay the CCDS in this child. Discovery of the novel variant has also expanded the mutational spectrum of the SLC6A8 gene.

Objective To study the risk factors and prognosis of post-transplant diabetes mellitus (PTDM) in recipients with steatotic donor livers.Method The clinical data of 182 patients who underwent liver transplantation from donors with liver steatosis in Tianjin First Central Hospital from June 2002 to December 2010 were retrospectively analyzed.There were sixteen patients with PTDM and one hundred sixtysix without PTDM.The clinical data of these patients were compared and the risk factors were evaluated by COX regression analysis.The 1-,3-,5-year cumulative survival rates were analyzed after liver transplantation.Result The variables which included sex,pretransplant serum creatinine level,model for end-stage liver disease (MELD) score,intraoperative red blood cell transfusion,and post-transplant biliary complications were significantly different between the two groups.Multivariate Cox regression analysis showed that living-donor,pretransplant fasting blood glucose and post-transplant biliary complications could affect the survival time of patients in PTDM group.The 1-,3-and 5-year cumulative survival rates in the PTDM group were 81.3％,68.8％ and 62.5％,which were significantly lower than those in the non-PTDM group (95.2％,86.1％ and 80.7％ respectively,P ＜ 0.05).Conclusions Living-donation,pretransplant fasting blood glucose and post-transplant biliary complications had a worse prognosis in the PTDM group.A comparatively better long-term survival after liver transplantation can be achieved by reducing the risk factors and the occurrence of PTDM.

Objective To evaluate the effect of berberine on fatty liver ischemia-repeffusion (I/R) injury and the relationship with endoplasmic reticulum stress in liver tissues.Methods Thirty-two male Wistar rats,aged 4 weeks,weighing 100-150 g,were divided into 4 groups (n=8 each) using a random number table method:control group (group C),fatty liver group (group FL),I/R group and berberine group (group BBR).Rats were fed a normal fat diet for 12 weeks,normal saline 3.5 ml was given intragastrically for 4 weeks starting from 9th week,and rats only underwent simple laparotomy in group C.Rats were fed a high-fat diet (45％ energy originating from fat) for 12 weeks,and the other treatments were similar to those previously described in group C.Rats were fed a high-fat diet (45％ energy originating from fat) for 12 weeks,normal saline 3.5 ml was given intragastrically for 4 weeks starting from 9th week,and then the model of liver I/R injury was established in group I/R.Rats were fed a high-fat diet (45％ energy originating from fat) for 12 weeks,berberine solution (300 mg/kg) 3.5 ml was given intragastrically for 4 weeks starting from 9th week,and then the model of liver I/R injury was established in group BBR.Hepatic ischemia was induced by clamping the portal vein,hepatic artery,right gastric vein,and supra-and inferior-hepatic vena cava to perform cold perfusion with 4 ℃ lactated Ringer's solution lasting for 30 min,followed by reperfusion.The serum triglyceride (TG) concentrations were determined after 4,8 and 12 weeks of diet.Blood samples were collected at 6 h of reperfusion for measurement of serum aspartate transminase (AST) and alanine transaminase (ALT) concentrations.Livers were removed after blood sampling at 6 h of reperfusion and liver tissues were obtained and stained with oil red O and haematoxylin and eosin for examination of pathological changes and for determination of the expression of Bip,CCAAT/enhancer-binding protein homologous protein (CHOP),protein kinase RNA-like endoplasmic reticulum kinase (PERK) and phosphorylated PERK (p-PERK) (by Western blot).p-PERK/PERK ratio was calculated.Results Compared with group C,the serum TG,ALT and AST concentrations were significantly increased,the expression of Bip and CHOP was up-regulated,p-PERK/PERK ratio was increased (P＜0.05),lipid deposition was increased,and liver steatosis was found in group FL.Compared with group FL,the serum AST and ALT concentrations were significantly increased,the expression of Bip and CHOP was up-regulated,pPERK/PERK ratio was increased (P＜0.05),and the pathological changes of liver tissues were accentuated in group I/R.Compared with group I/R,the serum TG,ALT and AST concentrations were significantly decreased,the expression of Bip and CHOP was down-regulated,p-PERK/PERK ratio was decreased (P＜ 0.05),lipid deposition was reduced,and the pathological changes of liver tissues were significantly attenuated in group BBR.Conclusion Berberine can ameliorate fatty liver I/R injury,and the mechanism may be related to inhibiting endoplasmic reticulum stress in liver tissues of rats.

Objective To explore the effect of berberine (BBR) on steatotic liver ischemia reperfusion injury and analyze the role of endoplasmic reticulum stress and autophagy .Methods Thirty-four Wistar rats were fed with a high-fat diet for 12 weeks and 2 rats were randomly selected after 8 weeks to observe pathological changes and confirm the model of steatotic liver successfully .Then before opening and closing abdominal cavity ,32 rats were divided into I/R group (normal saline was intragastrically 4 weeks before performing cold I/R treatment) ,BBR group (normal saline was replaced by BBR ,BBR was intragastrically at a dose of 300 mg·kg-1 ·d-1 weeks and others were the same as I/R group) and TG group (TG was intraperitoneally at a dose of 0 .2 mg·kg-124h pre-operation and others were the same as BBR group ) .Then the rats were sacrificed at 6h post-reperfusion .Blood samples were collected from inferior vena cava and hepatic tissues harvested .The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were detected ,histopathologic changes observed by Hematoxylin & Eosin (HE) staining ,oxidative stress and inflammation determined by ELISA kit and the expressions of p-PERK ,CHOP ,Bip ,LC3 ,Beclin-1 and p62 detected by Western blot .Results As compared with Sham group ,the serum levels of ALT and AST were significantly higher in I/R ,BBR and TG groups (P < 0 .05) .And hepatic histological changes were severe and oxidative stress increased in parallel with the enhancement of pro-inflammation (P< 0 .05) .In BBR group ,the level of hepatic enzymes declined ,liver injury was milder ,oxidative stress decreased and pro-inflammation was lesser compared with I/R and TG groups (P< 0 .05) .Additionally ,as compared with sham group ,the expressions of p-PERK ,CHOP ,Bip ,LC3 ,Beclin-1 and p62 were up-regulated in I/R and BBR groups (P < 0 .05) .TG group increased the levels of LC3 ,Beclin-1 and p62 (P< 0 .05) .Interestingly ,compared with I/R group ,BBR pretreatment down-regulated the expressions of p-PERK ,CHOP ,Bip ,LC3 ,Beclin-1 and p62 (P< 0 .05) .TG group had the higher expressions of LC3 ,Beclin-1 and p62 than those of BBR group (P< 0 .05) .Conclusions BBR pretreatment can protect steatotic liver ischemia reperfusion injury .And the mechanisms may be attributed to the inhibitions of endoplasmic reticulum stress and autophagy .

Objective To explore the mechanism by which CD137 signal regulates the aging of vas-cular smooth muscle cells(VSMCs).Methods Thirty 8-week-old male C57BL/6J mice were ran-domly divided into a young group(8 weeks old)and an aged group(80 weeks old),with 30 mice in each group.After corresponding periods of feeding,the mice were euthanized,and the plasma and aortic blood vessels were isolated.In the cell experiments,normal VSMCs were divided into a control group,bleomycin(BLM)group,combined agonist group,and combined inhibitor group.The cellular senescence level of VSMCs was assessed using a cellular senescence β-galactosidase staining kit.Western blotting and PCR were employed to examine the expression of senescence-related proteins in tissues and cells,while ELISA was utilized to measure the expression of senes-cence-related inflammatory factors.Results The expression of CD137 and γ-H2AX in the aorta was significantly higher,while that of PCNA was obviously lower in the aged group than the young group(P＜0.05).The plasma level of CD137 was notably higher in the aged group than the young group(154.0±4.1 pg/ml vs 98.0±2.3 pg/ml,P＜0.05).Compared with the normal control group,there were significantly more aged VSMCs in the BLM group(P＜0.05).While,treatment of combined agonist resulted in larger amount of aged VSMCs when compared with the BLM group(P＜0.05),which was reversed by combined inhibitor treatment(P＜0.05).The levels of TNF-α,IL-6 and IL-1β were significantly elevated in the BLM group than the normal control group(P＜0.05).The combined agonist group had even higher levels of TNF-α,IL-6,and IL-1βthan the BLM group(P＜0.05),but the levels were decreased in the combined inhibitor group(P＜0.05).Compared with the normal control group,the expression of Bcl-2,γ-H2AX,P53,and P21 were significantly increased in the BLM group,combined agonist group,and combined inhibi-tor group,while that of PCNA was significantly decreased(P＜0.05).Compared with the BLM group,the expression of P53 and P21 in the combined agonist group showed an increase(P＜0.05),and the expression of P53 was significantly decreased in the combined inhibitor group(P＜0.05).Conclusion CD137 signal regulates the P53/P21 pathway to promote VSMC aging.

Objective:To investigate the role of group 3 innate lymphoid cells (ILC3) in skin wound healing, and to explore the underlying mechanisms.Methods:Twenty-four 5-week-old male C57BL/6 mice were randomly and equally allocated into 3 groups: the skin wound + ILC3 inhibitor group (referred to as ILC3 inhibitor group), the skin wound group, and the control group, with 8 mice in each group. Four days before the establishment of the wound model, mice in the ILC3 inhibitor group were intraperitoneally injected with 1 μg of ILC3 inhibitor every 2 days for a total of 2 doses, mice in the skin wound group were injected with an equal volume of physiological saline solution, and mice in the control group were fed normally. To establish a mouse skin wound model, a full-thickness circular incision with a diameter of 0.6 cm was made around the midpoint of the dorsal midline using a biopsy punch after the intraperitoneal injection of anesthetics, which was histologically confirmed to be a full-thickness injury. The size of the wounds was observed and recorded, photographs of the wounds were taken on days 0, 1, 3, 5, 7, and 9 after wounding, and corresponding wound healing rates were calculated. On day 9 after wounding, tissue samples were collected from the wound edges, and subjected to flow cytometry analysis to quantify ILC3 infiltrating around the skin wound, and hematoxylin and eosin (HE) staining was performed to assess the healing status of the skin wounds. Real-time quantitative polymerase chain reaction (qRT-PCR) was conducted to determine the mRNA expression of vitamin D receptor (VDR), Notch1, tumor necrosis factor-alpha (TNF-α), interleukin (IL) -17A, IL-17F, and IL-22 in the wound-edge tissues, and Western blot analysis to determine their protein expression. Statistical analysis was carried out by using one-way analysis of variance and t test. Results:On day 9 after wounding, the skin wound group showed an increased number of ILC3 in the wound-edge tissues (5.31% ± 1.47% vs. 3.10% ± 0.54%, P < 0.01), increased mRNA and protein expression of TNF-α, IL-22, IL-17A, and IL-17F (all P < 0.05), but decreased mRNA and protein expression of VDR (both P < 0.05) compared with the control group; the protein expression of Notch1 was significantly higher in the skin wound group than in the control group ( P < 0.05), but there was no significant difference in its mRNA expression between the two groups ( P > 0.05). On days 1, 3 and 5, the wound healing rates were significantly higher in the ILC3 inhibitor group (45.17% ± 9.90%, 61.58% ± 11.61%, 75.61% ± 9.12%, respectively) than in the skin wound group (25.87% ± 10.96%, 47.78% ± 13.81%, 64.55% ± 10.29%, respectively, all P < 0.05). On day 9, the ILC3 inhibitor group showed a decreased number of ILC3 around the wound (2.69% ± 0.95%, P < 0.01), decreased mRNA and protein expression of TNF-α, IL-22, IL-17A, and IL-17F in the wound-edge tissues (all P < 0.05), but increased mRNA and protein expression of Notch1 and VDR in the wound-edge tissues (all P < 0.05) compared with the skin wound group. On day 9 after wounding, histopathological examination with HE staining revealed continuous and intact epithelial structure, as well as dense and neatly arranged collagen fibers in the ILC3 inhibitor group, and the structures of hair follicles, blood vessels, and sebaceous glands were similar to those in the control group. Conclusions:Skin ILC3 infiltrated local wounds and were involved in the skin wound healing process through inflammatory factors such as TNF-α, IL-17A, IL-17F, and IL-22. Downregulating the number of ILC3 may promote skin wound healing by activating VDR and Notch1, as well as inhibiting the TNF-α signaling pathway and the expression of downstream inflammatory factors.

ObjectiveTo investigate the psychological tendency characteristics of vocational selection for college students with disabilities. MethodsA total of 155 college students with disabilities in four colleges and universities were investigated using Psychological Tendencies of Vocational Selection for College Students with Disabilities (PTVS). ResultsA total of 151 questionnaires returned finally. The principal component analysis extracted four factors, namely profession, capability, parental occupation and parental education, with a cumulative contribution rate of 74.98%. Clustering analysis clustered three categories, namely vocational capability and parental education dominated, profession and capability dominated, and profession dominated, which accounted for 20.5%, 31.1% and 48.3%, respectively. There were significant differences among the three categories in the dimensions of personal cognition, employment tendency, employment affect and employment will of PTVS (F > 7.021, P < 0.01). ConclusionThere are four dimensions of PTVS, i.e., the dimension of profession, the dimension of capability, the dimension of parental occupation and the dimension of parental education; while the PTVS could be divided into three categories, i.e., vocational capability and parental education dominated, profession and capability dominated, and profession dominated. For college students with disabilities, accurate career counseling and guidance should be provided according to the psychological structure of vocational selection and PTVS.

Objective:To explore the non-target metabonomics of serum in worker's pneumoconiosis (CWP) patients with latent tuberculosis and the biomarkers of latent tuberculosis infection of pneumoconiosis.Methods:In December 2018, 39 CWP inpatients from a hospital in Beijing were taken as subjects. The subjects were screened for latent tuberculosis using the in vitro release test of mycobacterium tuberculosis-interferon (IGRAs) test. According to the screening results, 21 positive patients with latent tuberculosis infection were selected as the latent tuberculosis group of pneumoconiosis. While 18 negative patients with CWP alone were selected as the pneumoconiosis group. Polarity components of metabolites were analyzed by UPLC-QTOF/MS. The data was processed with Progenesis QI software for multidimensional statistical analysis. Identification of structure of differential metabolites were matched through accurate mass and secondary mass spectrum. Searching the Human Metabolome Database (HMDB) , differential metabolites were imported into MetaboAnalyst 4.0 to analyze the metabolic pathways.Results:All 42 differential metabolites were screened out. Excepted for exogenous metabolites, 14 endogenous differential metabolites were identified. Compared with the pneumoconiosis group, 6 metabolites including PC [18∶4 (6Z, 9Z, 12Z, 15Z) /P-18∶1 (11Z) ], 3-Oxododecanoyl-CoA in the latent tuberculosis group were up-regulated, while 8 metabolites including the Stearoyl-CoA, (2S) -Pristanoyl-CoA were down-regulated. These results might be related to lipid, fatty acid and arachidonic acid metabolism pathways.Conclusion:There are significant differences in serum metabonomics between the patients with latent tuberculosis of pneumoconiosis and the patients with ordinary pneumoconiosis, which provide a reference for the study of biomarkers for the diagnosis of latent tuberculosis infection of pneumoconiosis.
