Objective To investigate the relationship between serum miR-505,miR-15 and endoscopic activity of ulcerative colitis(UC).Methods 98 patients with UC from May 2020 to May 2022 were selected as the observation group,and 80 patients with irritable bowel syndrome(IBS)were selected as the control group during the same period.The modified Mayo score was used to evaluate the endoscopic activity in patients with UC,and the relationship among the changes of serum miR-505 and miR-15 levels and the endoscopic activity in patients with UC was analyzed.Results The level of serum miR-505 in observation group was lower than that in control group,while the level of miR-15 in observation group was higher than that in control group(P<0.05).The level of serum miR-505 in patients with active UC was lower than that in patients with the healing stage,while the level of serum miR-15 in patients with active UC was higher than that in patients with healing stage(P<0.05).The serum miR-505 level of E3 type was lower than that of E2 type and E1 type,and the serum miR-15 level of E3 type was higher than that of E2 type and E1 type(P<0.05).The Mayo score of type E3 was higher than that of type E2 and E1(P<0.05).Pearson correlation analysis showed that serum miR-505 was negatively correlated with Mayo score(r =-0.51,P<0.05),while serum miR-15 was positively correlated with Mayo score(r = 0.54,P<0.05).Receiver operator characteristic curve(ROC curve)results showed that the cut-off value of miR-505 was 0.93,and the area under the curve(AUC)for evaluating the endoscopic activity of patients with UC was 0.67(95%CI:0.659～0.785),and the sensitivity and specificity were 73.24%and 68.55%,respectively.The cut-off value of miR-15 was 0.85,and the AUC for evaluating the endoscopic activity of patients with UC was 0.69(95%CI:0.672～0.814),and the sensitivity and specificity were 76.38%and 69.72%,respectively.The AUC for the joint evaluation of UC by both was 0.82(95%CI:0.809～0.912),and the sensitivity and specificity were 84.56%and 68.49%,respectively.Conclusion Serum miR-505 levels decrease and serum miR-15 levels increase in UC patients than IBS,and the level is closely related to patients'pathological conditions and endoscopic activity.Combined detection of serum miR-505 and miR-15 has a good value in evaluating endoscopic activity in UC patients.

Objective:To investigate the inhibitory effect of lycium barbarum polysaccharide(LBP)on apoptosis of Schwann cells(SCs)and its related mechanisms.Methods:The autophagy model was prepared by starvation treatment of RSC96 cells for 12 h,and the expressions of autophagy related proteins LC3 and p62 were detected by Western Blot.Cell Counting Kit-8(CCK-8)kits were used to detect the optimal concentration of LBP.RSC96 cells were randomly divided into Control group,Starvation group and Starvation+LBP group.The expressions of autophagy associated pro-teins(LC3,p62)and myelin associated proteins(p75NTR,PMP22,S100β)were detected by Western Blot or immu-nofluorescence staining.Annexin V/PI fluorescence staining was used to detect apoptosis of the cells.The cell cycle was analyzed by flow cytometry.Western Blot analysis of phosphorylation levels of pathway proteins Erk1/2 and Akt.Results:CCK8 results showed that the viability of damaged RSC96 cells was the best when LBP was 300 μg/ml.Com-pared with Control group,LC3-Ⅱ/LC3-I levels in Starvation group were significantly increased(P＜0.05).Compared with Starvation group,the proportion of apoptotic and necrotic cells in Starvation+LBP group was significantly de-creased,and the proportion of cells in S and G2/M stages was increased.The expression levels of LC3-Ⅱ,p75NTR,PMP22 and S100β were increased,while the expression levels of autophagy substrate protein p62 were decreased.In-creased expression of pathway protein p-Erk1/2(P＜0.05),while the expression of p-Akt protein decreased slightly.Conclusion:LBP can inhibit the apoptosis of SCs and promote the expression of myelin-related proteins by enhancing autophagy,which is related to the activation of Erk1/2 and/or the inhibition of Akt.

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 investigate the clinical efficacy of anal dimple anorectoplasty on female infants with congenital anal atresia combined rectal vestibular fistula.Methods:Clinical data of 69 female infants with congenital anal atresia combined rectal vestibular fistula admitted to Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from July 2012 to July 2022 were retrospectively analyzed.They were divided into 2 groups according to the surgical methods: 34 cases of anal dimple anorectoplasty(group A) and 35 cases of anterior sagittal anorectoplasty(group B). The operation time, length of stay, short-term complications, long-term complications and bowel function (determined by the Rintala score at 6 months postoperatively) of the two groups were compared.The difference in the incidence of postoperative complications between groups was compared by Chi- square test, and the remaining differences between groups were compared by the paired t-test. Results:The operative time [(80.18±9.29) min vs.(103.85±8.26) min] and postoperative hospital stay[(6.10±1.52) d vs.(7.63±2.40) d] in group A were significantly shorter than those of group B ( t=11.40, 2.62; all P<0.05). The Rintala total score at 6 months postoperatively in group A was significantly higher than that of group B[(19.36±0.93) points vs.(18.76±0.44) points]( t=3.20, P<0.05). There were no significant differences in the incidences of short-term [(4/34, 11.8%) vs.(7/35, 20.0%)] and long-term complications [(2/34, 5.9%) vs.(4/35, 11.4%)]between group A and group B ( χ2=0.75, 0.75; all P>0.05). Conclusions:Anal dimple anorectoplasty for female infants with congenital anal atresia combined rectal vestibular fistula is safe and effective.

Results:All operations were successfully performed . ERAT children started oral feeding earlier [(6.8±2.0) h vs. (12.3±2.0) h, t=-10.636, P<0.001], postoperative hospital stay was shorter [(3.2±1.3) d vs. (5.0±1.3) d, t=-5.360, P<0.001]. After 14 months follow up, the recurrence rate in the ERAT group was 6%. The complication rate of LA was 10%. Conclusion:ERAT is a safe and effective therapy in treating children with acute uncomplicated appendicitis with low,acceptable recurrence rate.

Objective:To analyze the characteristics and prognosis of hearing loss in children with bacterial meningitis.Methods:This was a single-center retrospective cohort study. Patients diagnosed with bacterial meningitis who were hospitalized in Beijing Children′s Hospital between 2010 and 2016 and older than 28 days and younger than 18 years at symptom onset were included in this study ( n=573). All clinical information including hearing assessment results during hospitalization were reviewed. All patients with hearing loss were followed up to repeat their hearing test and assess their hearing condition with parents′ evaluation of aural and (or) oral performance of children (PEACH). Patients were grouped according to their hearing assessment results, and Logistic regression analysis was used to analyze the risk factors for hearing loss in patients with bacterial meningitis. Results:Five hundred and seventy-three patients were enrolled in this study, including 347 males and 226 females. The onset age ranged from 29 days to 15.8 years. Two hundred and forty-six patients had identified causative pathogens, among whom 92 cases (37.4%) were pneumococcal meningitis cases. Hearing loss was found in 160 cases (27.9%) during hospitalization, involving 240 ears. Permanent hearing loss was found in 20 cases (16.9%), involving 32 ears. In the patients with permanent hearing loss, 87.5% (28/32) of ears were identified as severe or profound hearing loss during hospitalization. Logistic regression analysis showed that dystonia, the protein concentration level in cerebrospinal fluid>1 g/L, glucose concentration level lower than 1 mmol/L and subdural effusion were independent risk factors for hearing loss ( OR=2.426 (1.450-4.059), 1.865 (1.186-2.932), 1.544 (1.002-2.381) and 1.904 (1.291-2.809)). Conclusions:Hearing loss is a common sequela of bacterial meningitis in children. Most patients have transient hearing loss, but patients with severe or profound hearing impairment have a higher risk of developing permanent hearing loss.

Objective:To study the application value of health education based on self-efficacy theory in the management of patients with chronic obstructive pulmonary disease (COPD) outside the hospital.Methods:Using the convenient sampling method, a total of 66 COPD patients who were treated and discharged from the First Affiliated Hospital of Zhengzhou University from March to November 2018 were selected as the routine group, and 67 COPD patients who were treated and discharged from December 2018 to August 2019 were selected as the study group. The routine group adopted routine follow-up nursing, while the study group adopted health education based on self-efficacy theory on the basis of routine follow-up nursing. The rehabilitation compliance score and self-efficacy score of the two groups before the intervention, after the intervention and 6 months after the intervention were compared. The readmission rate from the beginning of the intervention to 6 months after the intervention were compared between the two groups.Results:After the intervention, the rehabilitation compliance score of the study group was (39.94±4.91) , which was higher than (33.29±4.60) of the routine group. At 6 months after intervention, the rehabilitation compliance score of the study group was (38.87±4.76) , which was higher than (31.75±4.10) of the conventional group. Repeated measurement analysis of variance showed that there was an interaction between the two groups in rehabilitation compliance score ( Ftime=84.532, Fgroups=10.241, Finteraction=9.785; P<0.05) . After intervention, the self-efficacy score of the study group was (141.36±20.76) , higher than (118.26±15.47) of the control group. On 6 months after the intervention, the self-efficacy score of the study group was (139.21±16.95) , which was higher than (108.51±15.01) of the routine group. Repeated measurement analysis of variance showed that there was an interaction between the two groups in self-efficacy scores ( Ftime=87.541, Fgroups=12.254, Finteraction=13.697; P<0.05) . At 6 months after intervention, the readmission rate of the study group was 16.42%, which was lower than 33.33% of the routine group, and the difference was statistically significant ( χ2=5.099, P=0.024) . Conclusions:The application of health education based on self-efficacy theory in the management of COPD patients outside the hospital can improve rehabilitation compliance and self-efficacy of patients and reduce the frequency of readmissions.

Objective To investigate the effect of miR-107 on the function of human non-small cell lung cancer cell line A549 and its possible target genes.Methods The experiment was divided into the liposome+miR-107 mimics overexpression group(OV-miR-107 group),liposome+miR-107 inhibiting mimics downregulation group(KD-miR-107 group)and liposome+ negative control mimics group(NC group).The cell transfections of siRNA were siRNA-1,siRNA-2 and siRNA-3 respectively.The cellular prolifer-ation capacity was detected by MTT assay.The cellular cycle was detected by flow cytometry.The dual luciferase reporter gene as-say was performed to detect the downstream target gene of miR-107.The real time quantitative reverse transcription PCR and Western blot were respectively employed to examine mRNA and protein expression levels of downstream target gene.Results miR-107 inhibited the proliferation of A549 cells in a time-and dose-dependent manner(P<0.05).miR-107 arrested more A549 cells at the G0G1phase,and the proportions of S phase and G2M phase were decreased(P<0.05).miR-107 combinded with the 246 bp-253 bp of CCNE1 3′-untranslated region,and decreased mRNA and protein expression of CCNE1(P<0.05);after down-regulating CC-NE1 in A549 cells,siRNA-2 inhibited cellular proliferation(P<0.05)and blocked the cells to stay at G0G1phase(P<0.05).Con-clusion miR-107 inhibits the proliferation of human non-small cell lung cancer cell line A549 and regulates the cellular cycle by tar-geting CCNE1.

Objective: To summarize the clinical characteristics, virological and histopathological features, clinical outcome of Epstein-Barr virus-positive lymphoproliferative disease (EBV⁺LPD) in children. Methods: The clinical and follow-up data of 13 children histopathologically diagnosed as EBV⁺LPD in the Department of Infectious Disease of Beijing Children's Hospital between January 2011 and December 2016 were summarized. Results: Of the 13 patients, 5 were males and 8 females. The median age of disease onset was 6.0 years (range 1.3 to 15.0 years). The median duration between disease onset and diagnosis was 3 months (range 1 to 24 months). All the 13 patients had fever, 9 cases had hepatosplenomegaly and lymphoadenopathy, 4 cases had only lymphoadenopathy, 7 cases had reduced peripheral blood cells, 7 cases had lung involvement, 3 cases had central nervous system involvement, 3 cases had cardiac involvement, 3 cases had intestinal involvement, 2 cases had skin involvement and 1 case had abdominal mass. All the 13 patients underwent whole blood EBV-DNA PCR examination and the copies ranged from 1×10⁸/L to 1×10¹¹/L. Pathology of lymph node confirmed 6 cases, skin pathology confirmed 2 cases, lung pathology, ileum mucosa pathology, liver pathology, abdominal mass pathology and bone marrow pathology confirmed 1 case each. Among 13 patients, 9 cases presented with EBV-positive T cell lymphoproliferative disease(EBV⁺ T-LPD), 2 cases with hydroa vacciniforme (HV) and 2 cases with EBV-positive diffuse large B-cell lymphoma (EBV⁺ DLBCL) . All the patients were followed up for 2 days to 65 months after discharge. Among 9 cases of EBV⁺T-LPD, 1 case died in a short time, 1 case died after evolved to T-cell lymphoma, 2 cases recovered after hematopoietic stem cell transplantation, 1 case recovered after the chemotherapy of hemophagocytic lymphohistiocytosis(HLH) 2004 protocol and 4 cases were stable now. Of 2 cases of HV patients, 1 case died after evolved to HV like lymphoma and the other still have symptoms. Among 2 cases of EBV⁺ DLBCL, 1 case died shortly after discharge and the other was still stable after chemotherapy. Conclusions Chronic recurrent fever, lymphadenopathy and hepatosplenomegaly are the most common clinical manifestations in children with EBV⁺LPD. Involvement of lung, central nervous system, intestinal tract, skin and other organs are also involved frequently. For children with chronic fever of unknown cause and accompanied by lymphadenopathy and (or) hepatosplenomegaly, EBV ⁺ LPD should be considered highly when the whole blood EBV-DNA load continues to increase significantly, early biopsy of the proliferative lesion should be performed to make a definite diagnosis. The prognosis of EBV ⁺ LPD is poor, and some evolve to lymphoma, hematopoietic stem cell transplantation is an effective way to treat this disease.
