Objective:To evaluate the safety and efficacy of enhanced recovery after surgery(ERAS) in the perioperative period of congenital choledochal cysts in children.Methods:This is a multicenter prospective randomized controlled study. The clinical data of 273 pediatric congenital choledochal cysts(CCC) patients who underwent surgery at 14 medical centers with complete follow-up data were collected through the medical data analysis platform. Among them, 123 cases in ERAS group were managed perioperatively in strict accordance with ERAS mode, and 150 cases in conventional group were managed according to traditional mode. The length of hospital stay,time to first farting, time to complete feeding, the incidence of complications, cost and readmission rate within 30 days,stress indexes and liver function were compared between the two groups.Results:Compared with the conventional group, median time to start farting (2.0 d vs. 3.0 d, P<0.001), median time to complete feeding (5.0 d vs. 7.0 d, P<0.001), median postoperative hospitalization time (6.0 d vs. 9.0 d, P<0.001),the median total length of stay(13.0 d vs. 15.0 d, P<0.001) were shorter,the median hospitalization cost (37,000 yuan vs.43,000 yuan P<0.001) was lower, and stress indexes recovered quickly. The incidence of postoperative hospital stay and readimission rate within 30 d were not statistically different between the two groups. Conclusion:It is safe and feasible to implement ERAS for children with CCC in the perioperative period, which can reduce stress response, speed up recovery,and save medical costs.

Objective To explore the expression of mocro RNA(miR)-142-5p and suppressor of cytokine signaling 1(SOCS1)mRNA in peripheral blood mononuclear cells(PBMC)of mice and clinical patients with ankylosing spondylitis(AS)and their impact on immune function.Methods The mRNA levels of miR-142-5p and SOCS1 in PBMC of 30 patients with AS(Patient group)and 30 healthy controls(Health group)treated in the First People's Hospital of Shangqiu from January 2022 to March 2023 were measured by quantitative real time PCR(qRT-PCR).AS mice models were induced by bovine proteoglycan combined with complete Freund's adjuvant,and these mice were divided into control group,model group,NC group and antagomir group.Normal saline was injected into tail vein in control group and model group,and NC-antagomir and miR-142-5p-antagomir were injected into tail vein in NC group and antagomir group,respectively.After 2 weeks of treatment,the arthritis symptom scores of mice in each group were evaluated.The morphology of ankle joint was evaluated by hematoxylin eosin(HE)staining.The levels of Th1 cytokine interferon-γ(IFN-γ),Th2 cytokine interleukin-4(IL-4),Th17 cytokine interleukin-17(IL-17)and Treg cytokine forkhead box protein P3(FOXP3)in PBMC of mice were detected by ELISA method.The mRNA and protein expression of miR-142-5p,SOCS1,IFN-γ,IL-4,IL-17 and FOXP3 in PBMC and ankle joints were detected by qRT-PCR and Western blot.Results Compared with Health group,the level of miR-142-5p in PBMC of patient group was increased(1.00±0.21 vs 3.03±0.99,t=10.997,P＜0.001),while the level of SOCS1 mRNA was decreased(1.00±0.18 vs 0.41±0.09,t=15.956,P＜0.001).Compared with control group,miR-142-5p level(1.00±0.04 vs 4.00±0.52)and the mRNA and protein levels of IFN-γ and IL-17 in ankle joint tissue of model group were increased,while the mRNA and protein levels of SOCS1,IL-4 and FOXP3 were decreased,with significant differences(t=23.356,31.420,48.056,47.224,38.035,29.007,54.183,28.123,55.155,26.758,45.346,all P＜0.05).The arthritis symptom score was increased(7.83±0.94 vs 0.00±0.00,t=22.212,P＜0.05),and the ankle joint structure was damaged.Serum IFN-γ,IL-17 levels,IFN-γ/IL-4 ratio(0.81±0.08 vs 2.08±0.33)and IL-17/FOXP3 ratio(0.41±0.03 vs 1.27±0.10)were increased,and the differences were statistically significant(t=15.382,35.779,8.934,35.130,all P＜0.05).Compared with NC group,miR-142-5p level(3.89±0.33 vs 1.47±0.10),the mRNA and protein levels of IFN-γ and IL-17 in ankle joint tissue of antagomir group were decreased,while the mRNA and protein levels of SOCS1,IL-4 and FOXP3 were increased,and the differences were statistically significant(t=18.846,22.969,43.454,32.617,23.259,20.881,41.832,11.994,32.977,15.190,35.834,all P＜0.05).The arthritis symptom score was decreased(7.42±1.24 vs 2.75±0.75,t=13.233,P＜0.05),and the shape of the ankle joint of the rats was improved.Serum IFN-γ,IL-17 levels,IFN-γ/IL-4 ratio(1.22±0.11 vs 1.91±0.19)and IL-17/FOXP3 ratio(0.69±0.05 vs 1.23±0.12)were decreased,and the differences were statistically significant(t=8.688,22.972,3.785,22.007,all P＜0.05).Conclusion MiR-142-5p was highly expressed in AS.Down-regulation of miR-142-5p using antagonists may reduce Th1/Th2 ratio and Th17/Treg ratio through up-regulation of SOCS1,there by improving the immune balance of AS mice and inhibiting the progression of AS.

Objective To explore the relationship between the serum neuropeptide Y (NPY) levels and the pathogenesis,therapeutic intervention of schizophrenia. Methods One hundard twenty-five patients with schizophrenia (case group) with no medication for at least 4-week and 136 healthy controls (control group) were evaluated by Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and Positive and Negative Syndrome Scala (PANSS). Simultaneously blood tests were performed to detect serum NPY levels. In the case group, PANSS was evaluated and blood collected again after 4 weeks of treatment with olanzapine. Result At the baseline,the serum NPY concentration was significantly lower in the case group than in control group (t=-5.79, P<0.01). The scores of RBANS and its factors were significantly lower in the case group than in control group (all P<0.01). The concentration was positively correlated with the score of the attention factor for RBANS scale (r=0.20, P=0.04). After treatment with olanzapine for 4 weeks,the serum NPY level in the case group was significantly increased (t=-2.23,P=0.03).The scores of PANSS total scale and subscale were significantly decreased(all P<0.01).There was no significant correlation between alterations of the serum level of NPY and PANSS total or subscale scores from baseline to 4-week (all P>0.05). Conclusion The present study has revealed a significant decrease in serum NPY levels in patients with schizophrenia which can be attenuated by treatment of Olanzapine.The action of Olanzapine may be related to the mechanism of action of Olanzapine.However,there is no correlation between alterations of the serum level of NPY and the improvement in the patientˊs clinical symptoms.

Objective To investigate the molecular mechanism of colistin resistance mediated by mcr-1and pmrAB genes in clinical Escherichia coli ( E. coli) isolates. Methods A total of 1988 clinical E. coli isolates were collected from the First People′s Hospital of Shangqiu from 2010 to 2017 and screened for colistin-resistant isolates using agar dilution method. The minimum inhibitory concentrations ( MICs) of nine common clinical antibiotics were determined using broth microdilution method. PCR and sequencing analysis were performed to detect the colistin resistance genes of mcr-1 and pmrAB. Conjugation experiments were used to test the transferability of the plasmid carrying mcr-1 gene. S1-PFGE and Southern blot were used to locate the plasmid carrying mcr-1. All colistin-resistant E. coli isolates were typed by multilocus se-quence typing ( MLST) . Results Six colistin-resistant E. coli isolates were obtained by agar dilution meth-od. The results of susceptibility testing showed that all of the six isolates were multidrug resistant. PCR and sequencing analysis revealed that four out of the six strains carried mcr-1 gene, and the other two isolates both had an amino acid substitution (L167P) caused by pmrB gene mutation. The results of conjugation ex-periments, S1-PFGE and Southern hybridization analysis showed that the plasmids of four mcr-1 gene-posi-tive E. coli strains were located on a conjugative plasmid about 60 kb in length. MLST analysis classified the six isolates into six distinct sequence types ( STs) . Conclusion This study suggested that mcr-1 gene and mutations in pmrAB gene were the main mechanisms mediating the resistance of E. coli to colistin. In clinical practice, the occurrence and spread of colistin-resistant E. coli should be further monitored, and the rational use of antibiotics should be promoted to prevent the spread of colistin-resistant strains.

Objective To determine the frequency of depression in patients with Parkinson' s disease(PD) and healthy controls over 50 years of age and to analyze the characteristics and influencing factors of PD with depression(PDD) in Nanjing.Methods One hundred and twenty-six PD patients were diagnosed and assessed using Self-rating Depression Scale (SDS) and Hamilton Depression Scale (HAMD).The frequency,characteristics and influencing factors of depression were statistically analyzed,and the factor analysis of HAMD was carried out.Also,one hundred and twenty-four healthy subjects over the age of 50 were selected as the control group.Ressults The incidence of depression in PD group was 48.4％ ( 61/126):15.1％ (19/126) for mild depression,27.8％ (35/126) for moderate depression,5.6％ (7/126) for severe depression.The incidence of depression in the control group was 9.7％ (12/124):5.7％ (7/124) for mild depression,2.4％ (3/124) for moderate depression,1.6％ (2/124) for severe depression.There was a significant difference between these two groups( x2 =45.36,P ＜ 0.01 ).Univariate and Logistic regression analysis revealed that a high frequency of depression occurred in patients with long PD duration,high H-Y stage and UPDRS Ⅲ.According to each factor analysis of HAMD,the scores of cognitive impairment,tardiness,anxiety and sleep disturbances of the PD patients with depressive syndromes were higher than that of the control group.Conclusion Depression is a relatively common complication of PD in Nanjing which is associated with long PD duration,severity of motor disturbances and increasing H-Y stage.
