ABSTRACT
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.
ABSTRACT
Objective:To evaluate endoscopic retrograde appendicitis therapy in treatment of children with acute uncomplicated appendicitis.Methods:Sixty children patients were admitted at the Affiliated Hospital of Zhengzhou University from Oct 2019 to Jun 2021 and were divided into ERAT group ( n=30) and LA group ( n=30). 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.
ABSTRACT
Objective:To evaluate the effect of laparoscopic-assisted anorectoplasty in the treatment of children′s congenital anal atresia.Methods:In this study , 49 children undergoing laparoscopic-assisted anorectoplasty between Mar 2009 and Mar 2015 were compared in terms of outcomes with 42 children under going posterior sagittal anorectoplasty during this period.The post-operative complications, bowel functions and courses were evaluated.Results:The ratio of primary healing in laparoscopic-assisted anorectoplasty was higher than posterior sagittal anorectoplasty(22 % vs. 10%, χ 2=4.306, P=0.038), the age of sequential operation in the former was lower than control group [(9.9±6.5) d vs. (13.4±5.1) d, t=2.823, P=0.003]. The perioperative complications were lower than that in the control group(20% vs. 50%, χ 2=8.817, P=0.003), the bowel function was better than control group(χ 2=7.419, P=0.025). Conclusions:Perioperative complications in laparoscopic-assisted anorectoplasty is lower than posterior sagittal anorectoplasty, with better bowel function and higher primary healing rate.
ABSTRACT
Objective@#To explore the effect of nursing intervention on the biofeedback effect of functional constipation in children.@*Methods@#A total of 112 children (4-16 years old) who were diagnosed with functional constipation in the Department of Pediatric Surgery of the First Affiliated Hospital of Zhengzhou University were randomly divided into the experimental group (54 cases) and the control group (53 cases). Children in the experimental group were treated with biofeedback training and personalized nursing intervention for functional constipation in children. The control group used biofeedback combined with traditional nursing intervention to treat functional constipation in children. The WHO-5 (World Health Organization′s five physical and mental health) scales were used to compare the effects of the two groups and were followed up for 3-6 months.@*Results@#A total of 107 children completed the study, 54 in the experimental group and 53 in the control group. There were no significant differences in the scores of the WHO-5 scale and clinical symptoms between the two groups before the intervention (P>0.05). After intervention, the total score of WHO-5 in the experimental group was (21.69± 2.28), the total score of clinical symptoms was (6.56±1.16), the total score of WHO-5 in the control group was (17.85±3.189), and the total score of clinical symptoms was (9.04±2.121). The difference was significant (t=-7.146, t=7.491, P<0.01).@*Conclusion@#Personalized nursing intervention can enhance the effect of biofeedback training on children and adolescents with functional constipation and improve their quality of life.
ABSTRACT
Objective@#To explore the long-term efficacy of laparoscopic-assisted anorectoplasty and conventional anorectoplasty in the treatment of children with high and middle anal atresia.@*Methods@#A retrospective cohort study was used. Inclusion criteria: (1) children with high and middle anal atresia; (2) complicated with rectourethral or rectovesical fistula; (3) complete follow-up data. Exclusion criteria: (1) complicated with 21-trisomy; (2) cerebral palsy and other mentaldisabilities; (3) Currarino syndrome; (4) FG syndrome. Clinical data of 88 patients with middle and high anal atresia, who complicated with rectourethral fistula or rectovesical fistula, and underwent anoplasty at Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from January 2009 to June 2014 were enrolled in the study and analyzed. There were 24 cases with middle atresia and 64 cases with high atresia. All the cases were divided into 2 groups based on the operative method: laparoscopic group (laparoscopic-assisted anorectoplasty, 49 cases), pena group (posterior sagittal anorectoplasty, 39 cases). The demographic features of two groups were comparable. There were no statistically significant differences in gender, age, body mass, classification of anomaly types and sacral ratio (all P>0.05). Student t test and Chi square tests were used to compare the surgical conditions (operative time, postoperative hospital stay and complications), anal function (Kelly score), constipation (Krickenbeck constipation score) and anorectal pressure.@*Results@#Children of both groups all completed operation ssuccessfully. There were no statistically significant differences between laparoscopic group and pena group in the operative time [(120±31) minutes vs. (112±23) minutes, t=1.343, P=0.091] and postoperative hospital stay [(7.1±2.3) days vs. (10.7±3.3) days, t=6.021, P=1.000]. Complications were more common in the pena group [16.3% (8/49) vs. 35.9% (14/39), χ2=4.436, P=0.035]. The main complications in laparoscopic group were anal prolapse (8.2%, 4/49) and anal stenosis (6.2%, 3/49), while in pena group were anal stenosis (12.8%, 5/39) and perioperative perianal skin erosion (10.3%, 4/39). As for the anal function, the degree of feces, defecation control and sphincter contractility, the single scoring differences of Kelly scoring system were not statistically significant between the two groups, but the proportion of good function in the laparoscopic group was higher than that in the pena group [67.3% (8/49) vs. 38.5% (15/39), χ2=7.308, P=0.007]. Constipation occurred in 6 (12.2%) patients in the laparoscopic group, of whom 5 were improved by diet regulation and 1 required laxatives, while 9 (23.1%) patients developed constipation in the pena group, of whom 4 were improved by diet regulation and 5 required long-term laxatives. The difference of constipation ratio was not statistically significant (χ2=1.802, P=0.180). There were no cases of Krickenbeck constipation grade 3. Compared to the pena group, the laparoscopic group had higher anal resting pressure [(33.35±9.69) mmHg vs. (27.68±10.74) mmHg, t=2.599, P=0.011], higher dilating pressure [(9.00±5.61) mmHg vs.(6.51±3.24) mmHg, t=2.462, P=0.016], higher maximal squeeze pressure [(65.80±17.23) mmHg vs. (56.74±18.93) mmHg, t=2.389, P=0.019] and longer maximal contraction time [(21.16±5.02) seconds vs. (18.44±7.24) seconds, t=2.079, P=0.041]. The rectal resting pressure [(5.36±3.00) mmHg vs. (4.61±3.93) mmHg, t=1.015, P=0.312] was not statistically significantly different.@*Conclusions@#Compared with posterior sagittal anorectoplasty, laparoscopic-assisted anorectoplasty in the treatment of high and middle anal atresia has better long-term efficacy with less perioperative complications.

Objective To establish the expression profiles of microRNA (miRNA) in SMMC-7721 and CCC-HEL-1 cell lines in order to provide new clues to study the mechanism of miRNA function in hepatocellular carcinoma (HCC) and its treatment. Methods SMMC-7721 and CCC-HEL-1 cell lines were cultured in vitro. Total RNAs were extracted by TRIzol, followed by RNA quantification and quality control. The RNAs were used to detect the expression of miRNA in these two cell lines by miRNA array. The miRNA of interest was then verified by real-time PCR. Results In total,238 differentially expressed miRNAs were found, including 154 overexpressed and 84 underexpressed miRNAs. 64 miRNAs were upregulated more than 4 times and26 miRNAs were upregulated more than 10 times. 22 miRNAs were downregulated more than 4 times 10 miRNAs weredownregulated more than 5times, and 1 miRNA was downregulated more than 10 times. Real-time PCR validation suggested that has-miR-205 and has-let-7f in liver cancer increased by 2. 7 and 2. 3 times, respectively.Conclusion There are differences in the expression of miRNA between the SMMC-7721 and CCC-HEL-1 cell lines and the profiles of miRNA expression were established for both cell lines. It was found that has-miR-205 and has-let-7f were upregulated in liver cancer.
