Objective:To explore the clinical phenotype and genetic characteristics of a pediatric child with RELA-associated autoinflammatory disease (RAID) caused by a RELA gene variant, and to review the reported cases in the literature. Methods:A pediatric child with RAID who presented with recurrent fever, vomiting, and oral ulcers for over 5 years was selected as the study subject. The child visited the Women and Children′s Hospital of Ningbo University in August 2023. Clinical data were collected, and peripheral blood samples were obtained from the child and his family members for whole exome sequencing (WES) and Sanger sequencing to identify and validate candidate variants. The pathogenicity of the variants was analyzed accordingly. Using the keywords " RELA" " NF-κB" " autoinflammatory disease" " tofacitinib" " sulfasalazine" a literature search was conducted in the China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, and PubMed from January 1, 2000 to December 13, 2023. This study was approved by the Medical Ethics Committee of the Women and Children′s Hospital of Ningbo University (Ethics No. EC2020-048).Results:① The child primarily manifested with recurrent fever, vomiting, and oral ulcers. ② WES identified a heterozygous nonsense variant c. 985C>T (p.Arg329Ter) in the RELA gene, which was inherited from the mother. According to the American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants and the Clinical Genome Resource (ClinGen) recommendations for PVS1, this variant was classified as pathogenic (PVS1+ PM2_Supporting+ PP4). ③ Despite treatment with adalimumab and tocilizumab, the child′s symptoms persisted. Switching to tofacitinib improved oral ulcers, but fever and vomiting continued. The addition of thalidomide significantly alleviated fever and vomiting, and the patient′s growth and development remained normal. ④ A literature review identified 14 unrelated RAID families, including a total of 35 cases (including the present child). The main clinical features were recurrent oral ulcers, genital ulcers, skin problems, fever, diarrhea, abdominal pain, and vomiting. Conclusion:The nonsense variant c. 985C>T (p.Arg329Ter) in the RELA gene is likely the genetic cause of the child′s recurrent fever, vomiting, and oral ulcers. WES is valuable for timely diagnosis of RAID and provides a basis for clinical treatment strategies.

Objective: To examine the causal relationship between inflammatory factors and breast cancer using two-sample Mendelian randomization (MR) approach, so as to provide the basis for the prevention and treatment of breast cancer. Methods: Data of 91 inflammatory cytokines (n=14 824) and 5 subtypes of breast cancer (n=247 173) were collected from genome-wide association studies (GWAS). Single nucleotide polymorphism (SNP) associated with 91 inflammatory factors were selected as instrumental variables. MR analyses were performed using the inverse-variance weighted (IVW) method with inflammatory factors as exposure factors and breast cancer as outcome variables. The risk of type I error and the effect of multiple testing were reduced using the FDR correction method. The stability and reliability of the results were verified using Steiger test of directionality, MR-Egger regression, MR-PRESSO test and leave-one out method. Results: Twenty-three inflammatory factors, including β nerve growth factor, interleukin-5, cystatin D and C-X-C chemokine ligand 1 were statistically associated with breast cancer (all P<0.05). After FDR adjustment, only evaluated abundance of oncostatin-M was found to be statistically associated with an increased risk of Basal-like (triple-negative) breast cancer (OR=1.186, 95%CI: 1.081-1.302, P=0.001, q=0.029), and the other 22 inflammatory factors had a high risk of type I error (all q>0.1). The sensitivity analysis indicated that the results were robust. No instrumental variables were found to have a significant impact on the results, which could exclude the influence of heterogeneity, horizontal pleiotropy, and reverse causality on the outcome. Conclusion The increased abundance of oncostatin-M may increase the risk of Basal-like (triple-negative) breast cancer.

【Objective】 To explore the effect of physical fitness training on social adaptive behavior of children with global developmental delay (GDD), in order to provide treatment experience for GDD children. 【Methods】 From November 2021 to December 2022, a total of 60 children with GDD diagnosed and treated in the Third Affiliated Hospital of Jiamusi University were enrolled in this study, and were randomly divided into control group (n=30) and test group (n=30).The control group received routine rehabilitation treatment, and the test group received physical fitness training additionally.The intervention lasted for 12 weeks, with the frequency of 3times/week, 30min/time.All subjects were tested for physical fitness and children′s social adaptive behavior before and after training. 【Results】 Before treatment, the difference between the results of physical fitness test and social adaptive behavior scores of the GDD children in two groups was not statistically significant (P>0.05).After 3 months of treatment, the physical fitness test scores, except body mass index (BMI), and social adaptive behavior scores of the GDD children in two groups were significantly different from those before treatment (P<0.05), and the physical fitness test scores (except for height, weight and BMI) and the social adaptive behavior of the test group were better than those of the control group (t=2.363,4.020,3.331,3.338,P<0.05). 【Conclusion】 Physical fitness training can significantly improve the adaptive behavior, independent function, cognitive function and social/self-control ability of GDD children.

ObjectiveTo systematically evaluate the effect of action observation therapy (AOT) on upper limb function in children with cerebral palsy. MethodsRelevant literatures about the effect of AOT on upper limb function in children with cerebral palsy were retrieved from the databases of PubMed, Embase, Cochrane Library, Web of Science and CNKI, from the establishment to July 9, 2022. ResultsEleven articles involving 497 patients were included, which were mainly published in the past ten years. The studies included hospital-based studies with therapist supervision and home-based studies without therapist supervision, mainly related to the improvement of upper limb function of AOT in children with cerebral palsy. Experimental group performed actions related to activities of daily living, while control group mainly watched video clips excluding actions, 15 to 120 minutes a time, three to five times a week, with most of the intervention periods of three to four weeks. AOT improved the upper limb function of children with cerebral palsy in terms of body structure and function, and activity and participation, specifically grip strength, muscle tension, and hand dexterity and function. ConclusionHospital-based AOT with therapist supervision can improve upper limb function in children with cerebral palsy, while the effect of home-based AOT without therapist supervision and the long-term effect of AOT need to be further studied.

Objective: To explore the possible mechanism of moxibustion in myocardial protection of rats undergoing long-term fatigue exercise based on observing the classical pyroptosis pathway mediated by nuclear factor kappa-B (NF-κB)/nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3)/cysteinyl aspartate specific proteinase 1 (Caspase-1).Methods: A total of 50 specific-pathogen-free male Sprague-Dawley rats were bought. Ten unqualified rats were excluded, and the remaining 40 rats were divided into a normal group, a normal + Shenque (CV8) group, a model group, a model + non-meridian non-point group, and a model + Shenque (CV8) group according to the random number table method, with 8 rats in each group. Except for rats in the normal group and the normal + Shenque (CV8) group, rats in the other three groups were trained with an incline running table exercise protocol to create a long-term fatigue exercise model, 1 h/time, once a day for 5 d with 2 d off, for a total of 8 weeks. Rats in the normal group received no modeling or intervention. Rats in the normal + Shenque (CV8) group were not modeled but received mild moxibustion at Shenque (CV8); those in the model group were modeled only without intervention; those in the model + non-meridian non-point group received moxibustion at non-meridian and non-point spots after the modeling; those in the model + Shenque (CV8) group received moxibustion at Shenque (CV8) after modeling. The above moxibustion interventions were performed for 15 min/time once daily, for 5 d with 2 d off per week and a total of 8 weeks. Blood was collected from the femoral artery 4 h after the last exercise, and the serum interleukin (IL)-1β and IL-18 levels were measured. The NF-κB, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), Caspase-1, and gasdermin D (GSDMD) expression levels were detected by Western blotting. Myocardial morphology and pyroptosis were observed by hematoxylin-eosin (HE) staining and electron microscopy. Results: The HE staining results showed that the myocardial cells in the model group and the model + non-meridian non-point group were disorganized with blurred transverse lines, widened interstitial spaces, interstitial edema, and inflammatory cell infiltration. The structure of myocardial cells in the model + Shenque (CV8) group was clearly visible, with slightly widened interstitial spaces and occasional infiltration of inflammatory cells in the interstitium. Compared with the normal group, the serum IL-1β and IL-18 levels were increased, and myocardial NF-κB, NLRP3, ASC, Caspase-1, and GSDMD expression levels were elevated in the model group and the model + non-meridian non-point group (P<0.01). Compared with the model group, the above indicators did not change significantly in the model + non-meridian non-point group, while all the above indicators were decreased in the model + Shenque (CV8) group (P<0.01). Compared with the model + non-meridian non-point group, all the above biochemical indicators were decreased in the model + Shenque (CV8) group (P<0.01). Transmission electron microscopy showed that the mitochondria number was increased in the model group and the model + non-meridian non-point group, some of the mitochondrial lumen was irregularly enlarged, the cell membrane structure was unclear, and chromatin was aggregated. The mitochondria number was increased, the swelling was reduced, and the nuclear membrane structure was more intact in the model + Shenque (CV8) group. Conclusion: Moxibustion at Shenque (CV8) regulates the NF-κB/NLRP3/Caspase-1 pathway and reduces the pyroptosisin the myocardium of rats with long-term fatigue exercise, thus reducing the myocardial injury caused by long-term fatigue exercise.

OBJECTIVE: To compare the effects of cetrorelix and ganirelix in gonadotropin-releasing hormone antagonist (GnRH-ant) cycles for preventing premature luteinizing hormone (LH) surges and on clinical outcomes of IVF-ET cycles. METHODS: We retrospectively analyzed 2572 GnRH-ant cycles of fertilization and embryo transfer from January, 2013 to December, 2016, including 1368 cycles with cetrorelix treatment and 1204 cycles with ganirelix treatment. The baseline characteristics of the patients and the clinical outcomes of the two groups were compared. RESULTS: Compared with those receiving ganirelix treatment, the patients with cetrorelix treatment had a significantly younger age (33.10 33.89 years, < 0.001) and a lower body mass index (21.57 21.84 kg/m, =0.024). After adjustment for age and body mass index of the patients, no significant differences were found between the two groups in the levels of follicle-stimulating hormone (FSH), LH, estradiol (E), progesterone (P) levels either at the baseline or on the day of hCG triggering, or in the number of oocytes retrieved ( > 0.05). The two groups also had comparable percentages of patients with LH > 10 U/L on the day of hCG triggering (3.7% 3.2%) and similar spontaneous ovulation rate (0.6% 0.5%), clinical pregnancy rate (47.7% 45.9%) and live birth rate (37.5% 33.6%) following fresh embryo transfer ( > 0.05). The incidence of moderate to severe ovarian hyperstimulation syndrome, however, was significantly higher in ganirelix group than in cetrorelix group (0.7% 0.1%, =0.006). CONCLUSIONS Cetrorelix and ganirelix can achieve comparable effects for preventing premature LH surges and can achieve similar clinical outcomes of GnRH-ant cycles, but ganirelix is associated with a significantly higher incidence of moderate to severe ovarian hyperstimulation syndrome.

OBJECTIVE: To explore the causes of oocyte vitrification and its application in assisted reproduction. METHODS: We retrospectively analyzed the data of 26 patients with 27 cycles of oocyte vitrification cryopreservation undergoing intracytoplasmic sperm injection (ICSI) and embryo transfer between January, 2008 and October, 2018. The causes of oocyte vitrification and the outcomes of ICSI and clinical pregnancy were analyzed. RESULTS: The causes of oocytes vitrification included mainly azoospermia or severe spermatogenesis disorder of the husband, failure to obtain sperms from the husband, failure of the husband to be present on the day of oocyte retrieval and acute diseases of the husband to not allow sperm collection. A total of 274 oocytes were frozen in 27 oocyte retrieval cycles, and 217 eggs were thawed in 19 cycles with a survival rate of 81.11% (176/217). The normal fertilization rate, cleavage rate and high-quality embryo rate was 74.81% (98/131), 89.80% (88/98) and 36.73% (36/98), respectively. Fifteen patients underwent embryo transfer, and the clinical pregnancy rate and live birth rate was 53.33% (8/15) and 33.33% (5/15), respectively. Compared with patients below 35 years of age, the patients aged above 35 years had significantly lower oocyte survival rate after thawing (82.76% 74.42%, =0.211), clinical pregnancy rate (77.78% 16.67%, =0.041) and live birth rate (55.56% 0, =0.044). CONCLUSIONS Oocytes vitrification can be used as a remedy for infertile couples who fail to provide sperms due to male factors on the day of oocyte retrieval. Vitrification of the oocytes does not significantly affect the fertilization rate or the clinical pregnancy rate. The survival rate of the thawed oocytes is related to the age of the wife, and an age younger than 35 years can be optimal for achieving favorable clinical pregnancy outcomes after oocyte vitrification.

Objective To analyze the clinical characteristics in children with digestive tract poison-ing in emergency department and discuss the measures of prevention and treatment. Methods Four hundred and seventy-three cases with digestive tract poisoning who visited the emergency department of Zhengzhou Children′s Hospital were retrospectively analyzed from January 2015 to December 2017. The ages,toxic poi-soning causes,types,clinical features, laboratory examinations, hospitalization expenses and outcomes were analyzed. They were divided into drug poisoning and non-drug poisoning group to compare. Results There were 317 (67. 0%) cases aged 6 days to 3 years old,133 (28. 1%) cases aged 3 to 6 years old,23 cases (4. 9%) >6 years old. The incidence rate was similar in each season but slightly lower in winter. There were 462 (97. 7%) cases of accidental poisoning,of which 377 (79. 7%) cases were mistreated and 85 (18. 0%) cases were mistakenly fed by parents,other 11 (2. 3%) cases were non-accidental poisoning. Three hundreds and thirty-six (71. 0%) cases were drug poisoning,and 137 (29. 0%) cases were non-drug poisoning. Drug poisonings were higher in urban children than in rural children, the difference was statistically significant (χ2 ＝7. 037,P＝0. 008). The percentage of digestive symptoms and blood system symptoms in non-drug poi-soning group were higher than those in drug poisoning group,and the differences were statistically significant (54. 0% vs. 8. 3%,χ2 ＝120. 067,P<0. 001;7. 3% vs. 3. 0%,χ2 ＝4. 491,P ＝0. 034). The percentage of cardiovascular system symptoms and respiratory symptoms in the non-drug poisoning group were lower than that in the drug poisoning group,and the differences were statistically significant (1. 5% vs. 14. 9%, χ2 ＝17. 915,P<0. 001;2. 9% vs. 11. 0%,χ2 ＝8. 050,P＝0. 005). Except for liver function and myocardial en-zyme,the percentage of abnormal laboratory indicators(white blood cells,platelets,blood glucose,lactic acid, electrolyte,coagulation) in non-drug poisoning group were higher than those in the drug poisoning group,and the differences were all statistically significant(all P<0. 05). The hospitalization cost of the non-drug poison-ing group was greater than that of the drug poisoning group,and the difference was statistically significant (Z＝ －12. 444,P<0. 001). Both in the drug-poisoning group and non-drug poisoning group,the cure or im-provement rate of the <6 h treating group were higher than that of the >6h treating group,and the difference was all statistically significant(all P<0. 05). Conclusion Children with acute gastrointestinal poisoning are mostly infants and preschoolers,mainly accidental poisoning,and often taken by mistake. Drug poisonings are mostly found in cities and non-drug poisonings in rural areas. Non-drug poisoning children have more serious damages and higher hospitalization costs than drug poisoning children. Early treatment after poisoning is an important factor to improve cure rate.
