ObjectiveTo explore the potential mechanism of Xiaoqinglong Decoction （小青龙汤， XD） in the treatment of allergic rhinitis. MethodsForty-five rats were randomly assigned to a control group， a model group， a loratadine group， low-， medium- and high-dose XD groups， and low-， medium- and high-dose Mahuang Decoction and Cang'erzi Powder （麻黄汤合苍耳子散， MDCP） groups. Except for the control group， rats were administered with ovalbumin （OVA） and aluminum hydroxide via intraperitoneal injection for 14 days to establish an allergic rhinitis model. After the 14th-day injection， nasal stimulation was continued with 20 μl of 10% OVA solution to maintain the model. Rats in the control group and the model group received 10 ml/（kg·d） of saline， whereas those in the loratadine group were administered with 0.9 mg/（kg·d） of loratadine. The low-， medium- and high-dose XD groups were administered XD at the dose of 2.7， 5.4， and 10.8 g/（kg·d）， respectively. The low-， medium- and high-dose MDCP groups were administered MDCP at the dose of 2.43， 4.86， and 9.72 g/（kg·d）， respectively. All treatments were administered by gavage once daily for 7 consecutive days. One hour after the final gavage， nasal symptom scores were recorded for all group of rats. The next day， serum levels of immunoglobulin E （IgE）， interleukin-4 （IL-4）， and interleukin-13 （IL-13） were measured. HE staining was used to observe the pathological morphology of the nasal mucosal tissue. Quantitative reverse transcription PCR （RT-qPCR） and Western Blot were performed to assess mRNA and protein expression of thymic stromal lymphopoietin （TSLP） and OX40 ligand （OX40L） in the nasal mucosa. ResultsCompared to the control group， total nasal symptom score in the model group significantly increased （P＜0.01）. HE staining revealed disrupted and adhered cilia， thickened basement membranes， and extensive inflammatory cell infiltration in the nasal mucosa. Serum levels of total IgE， IL-4， and IL-13， as well as TSLP and OX40L mRNA and protein expression in the nasal mucosa， were significantly elevated in the model group （P＜0.05 or P＜0.01）. Compared to the model group， the total nasal symptom scores in all drug intervention groups were significantly reduced； the serum total IgE levels in the loratadine group， the low- and medium-dose XD groups， and the low- and high-dose MDCP groups were significantly reduced； and the serum levels of IL-4 and IL-13 in the high-dose XD group and the high-dose MDCP group decreased （P＜0.05 or P＜0.01）. Nasal mucosal structure was improved. Except for the low-dose MDCP group， all other intervention groups showed a significant reduction in TSLP and OX40L mRNA expression in the nasal mucosa （P＜0.01）. All doses of XD and the medium- and high-dose MDCP groups significantly decreased the protein levels of TSLP and OX40L （P＜0.05）. The medium-dose XD group exhibited more improvement of nasal symptom scores and greater suppression of expression of TSLP and OX40L mRNA， and TSLP protein levels compared to the loratadine group （P＜0.05）. ConclusionXD may protect nasal mucosa of rats and alleviate allergic rhinitis by suppressing the TSLP/OX40L pathway， thereby attenuating Th2-mediated immune responses.

ObjectiveTo observe the clinical efficacy of electroacupuncture in treatment of simple obesity patients and its effects on the metabolism-inflammation network. MethodsSeventy-two patients with simple obesity were randomly divided into a electroacupuncture group and a sham electroacupuncture group， with 36 patients in each group. In the electroacupuncture group， conventional acupuncture was applied at Zhongwan （CV 12）， bilateral Tianshu （ST 25）， bilateral Daheng （SP15）， Qihai （CV 6）， Guanyuan （CV 4）， bilateral Zusanli （ST 36） and Fenglong （ST 40）. The sham electroacupuncture group used placebo needle at same acupoints as the electroacupuncture group. Both groups were given sparse-dense waves with a frequency of 2/10 Hz， 30 minutes per session， 3 times a week， for a total of 8 weeks of treatment. The changes of human body parameters including body weight， body mass index （BMI）， waist circumference， and body fat percentage （BFP）， metabolic factors including serum fasting blood glucose （FBG）， triglyceride （TG）， total cholesterol （TC）， high density lipoprotein （HDL）， low density lipoprotein （LDL）， leptin， and ghrelin， and inflammatory factors including interleukin-6 （IL-6） and tumor necrosis factor α （TNF-α） were compared before and after treatment. Correlations between changes in leptin， ghrelin and inflammatory factors were further analyzed. ResultsWaist circumference was significantly reduced after treatment in both groups compared with baseline （P＜0.05）， and the post-treatment waist circumference was lower in the electroacupuncture group than in the sham electroacupuncture group （P＜0.05）； body weight， BMI and BFP decreased significantly after treatment compared to pretreatment levels in the electroacupuncture group （P＜0.05）. Serum leptin， IL-6 and TNF-α declined significantly after treatment in both groups versus baseline （P＜0.05）； the electroacupuncture group had lower post-treatment levels of leptin， IL-6 and TNF-α as well as larger pre-post changes than the sham group （P＜0.05）； ghrelin increased markedly after treatment in both groups （P＜0.05）， with higher post-treatment ghrelin and greater pre-post variation observed in the electroacupuncture group （P＜0.05）. In the electroacupuncture group， changes in ghrelin were negatively correlated with IL-6 and positively correlated with TNF-α （P＜0.01）； in the sham electroacupuncture group， ghrelin changes were negatively correlated with both IL-6 and TNF-α， whereas leptin changes were positively correlated with the two inflammatory markers （P＜0.01）. ConclusionElectroacupuncture can effectively improve clinical manifestations， as well as regulate serum metabolic and pro-inflammatory factors in patients with simple obesity， and discrepant correlation patterns of metabolism-inflammation are observed between the two groups.

Objective To investigate the effects of galectin-3(Gal3)on autophagy in high glucose-induced human telomerase reverse transcriptase-immortalized retinal pigment epithelial(hTERT-RPE)cells.Methods The hTERT-RPE cells cultured in vitro were randomly divided into a normal group(group C),a high glucose group(group HG),a high glu-cose+si-NC group(group HG+si-NC)and a high glucose+si-Gal3 group(group HG+si-Gal3).Reverse transcrip-tion polymerase chain reaction(RT-PCR)was used to detect the relative mRNA expression levels of Gal3,intercellular ad-hesion molecule(ICAM)-1,interleukin(IL)-6 and tumor necrosis factor(TNF)-α in hTERT-RPE cells of each group.The expression levels of IL-1 and IL-6 in the supernatant of hTERT-RPE cells were measured by enzyme-linked immunosorbent assay(ELISA).The expression level of reactive oxygen species(ROS),the activity of superoxide dismutase(SOD)and the content of malondialdehyde(MDA)in hTERT-RPE cells were analyzed by dichlorofluorescin diacetate(DCFH-DA)staining,the colorimetric method and the microplate method,respectively.The protein expression levels of Gal3,the ratio of microtubule associated protein 1 light chain 3(LC3)type Ⅱ to type Ⅰ(LC3 Ⅱ/LC3 Ⅰ),Beclin 1,and autophagy-associat-ed 5(ATG5)and 7(ATG7)in hTERT-RPE cells from each group were detected by Western blot analysis.After the hTERT-RPE cells in each group were transfected with double fluorescent mRFP-GFP-LC3 plasmids alone and with RFP-LAMP1 and GFP-LC3 plasmids jointly,the changes of autophagy flow in hTERT-RPE cells were detected by laser confocal microscopy.Results Compared with the group C,the group HG showed an increase in the expression of Gal3,IL-1,IL-6,TNF-α,ICAM-1,P62,ROS and MDA content(all P＜0.05).However,the expression of LC3 Ⅱ/LC3 Ⅰ,Beclin1,ATG7,ATG5,the SOD activity,and the number of red(autolysosomes)and yellow fluorescence spots(autophagosomes)of the double fluo-rescent mRFP-GFP-LC3 plasmid were all lower in the group HG than those in the group C(all P＜0.05).There was no sig-nificant difference in the number of yellow fluorescent spots(autolysosomes)co-located by RFP-LAMP1 and GFP-LC3 plas-mids between groups C and HG(P＞0.05).There were no significant differences in the expression levels of the above-mentioned indexes in hTERT-RPE cells between groups HG and HG+si-NC(all P＞0.05).The expression levels of Gal3,IL-1,IL-6,TNF-α,ICAM-1,P62,ROS and MDA content in hTERT-RPE cells of the group HG+si-Gal3 were lower than those of the group HG+si-NC(all P＜0.05).Compared with those in the group HG+si-NC,the expression levels of LC3 Ⅱ/LC3 Ⅰ,Beclin1,ATG7,ATG5,SOD activity,and the number of red and yellow fluorescent spots of the double fluo-rescent mRFP-GFP-LC3 plasmid were increased in the group HG+si-Gal3(all P＜0.05).There was no significant differ-ence in the number of yellow fluorescent spots co-located by RFP-LAMP1 and GFP-LC3 plasmids between groups HG+si-GaL3 and HG+si-NC(P＞0.05).Conclusion Gal3 is significantly elevated in hTERT-RPE cells induced by high glu-cose,resulting in impaired autophagy flow.It produces a direct regulatory effect on the formation of autophagosomes,and plays a highly active role in oxidative damage and expression of inflammatory factors in hTERT-RPE cells induced by high glucose.

Objective:To analysis the possible behavior of coders in the reform of Diagnosis Related Groups(DRG)payment mode.Methods:To collect through questionnaires the possible coders'behaviors,and extract the common factors of possible behaviors according to factor analysis,and cluster the coders by the K-means clustering method.Results:Classify the possible coders'behaviors into positive behaviors such as following coding norms and standards,and negative behaviors such as directly coding without detailed reading of medical records.Less than 25 years old were more inclined to adopt negative behaviors,and associate senior titles and higher cognitive level of DRG were more inclined to adopt positive behaviors.The coders are divided into"positive group"who tend to take positive behaviors and"negative group"who take negative behaviors.Conclusion:Coders are more likely to adopt positive behavior,and we should be pay attention to the impact of different demographic characteristics on coders.To adopt different management strategies for different categories of coders,and strengthen training through hierarchical classification,and enhance coders'cognitive of DRG are more conducive to the selection of positive behaviors.

OBJECTIVE: To explore the clinical phenotype and genetic etiology of a neonate with X-linked alpha-thalassemia mental retardation syndrome (ATR-X) caused by ATRX gene variant, and review related literature on children with ATR-X caused by ATRX gene variants. METHODS: A case of ATR-X neonate who was transferred to the First Affiliated Hospital of Zhengzhou University on February 11, 2022 for poor effect of treatment in the neonatology department of the hospital where he was born for 4 days due to "postnatal slow response, groaning, and cyanosis of the skin for 30 min" was selected as the study subject. 3 mL of peripheral blood was collected from the child and their parents, and genomic DNA was extracted for whole exome sequencing (WES). Sanger sequencing was used to verify the pathogenic gene variations in the child's family. The pathogenicity of genetic variant sites was assessed based on the Standards and Guidelines for the Interpretation of Sequence Variants by American College of Medical Genetics and Genomics (ACMG). The amino acid sequence conservation analysis of relevant variant proteins was conducted by the Universal Protein Resource Database (UniProt) and visual analysis of these variant proteins was performed by Swiss online protein three-dimensional modeling database (SWISS-MODEL). Using keywords such as "ATRX gene" and " X-linked alpha-thalassemia mental retardation syndrome" both in Chinese and English, relevant literature on ATR-X children caused by ATRX gene variants was retrieved from the CNKI, Wanfang Data Knowledge Service Platform, and PubMed databases, and the clinical phenotypes of ATR-X patients reported in the retrieved literature were analyzed. The literature retrieval time was set from the establishment of each database to December 31st, 2023. This study followed the research procedures approved by the Ethics Committee of the First Affiliated Hospital of Zhengzhou University (Ethics No. 2023-KY-1360-002), and informed consent of clinical study was signed by the guardian of the child. RESULTS: The child in this study presented with symptoms such as delayed response, feeding difficulties accompanied by vomiting, low body temperature, hypotonia in all extremities, apnea, abnormal hearing screening, and a Neonatal Behavioral Neurological Assessment (NBNA) score of 19 (lower than the normal range).Hemoglobin (Hb) electrophoresis suggested the presence of α-thalassemia. The results of WES and Sanger sequencing revealed a hemizygous missense variant c.668G>A (p.C223Y) in exon 9 of the ATRX gene in the child of the study, neither of the parents of the child carried this variant, indicating that it is a de novo variant. Based on the Standards and Guidelines for the Interpretation of Sequence Variants released by ACMG, this gene variant was assessed as pathogenic (PS2+PM2_Supporting+PP3_Strong+PP4_Strong). The results of amino acid sequence analysis revealed that the pathogenic variant site normally encodes cysteine, which is highly conserved among various animal species. This pathogenic variant can lead to alterations in the hydrogen bonding structure of ATRX protein, thereby affecting its structural stability. Based on the clinical manifestations and genetic testing results of the child in this study, a diagnosis of ATR-X syndrome was established Based on the literature retrieval strategy established in this study, 13 relevant articles concerning ATR-X syndrome in children caused by ATRX gene variants were retrieved, including 5 Chinese articles and 8 English articles, involving a total of 311 ATR-X children. Including the child in this study, the total number of ATR-X children reaches 312. All 312 children were male and presented with mental retardation. Among them, 45.8% (143/312) had coexisting α-thalassemia, 45.2% (141/312) had abnormal genital appearance, 44.2% (138/312) had facial malformations, and 30.8% (96/312) had hypotonia. Other phenotypes included microcephaly, skeletal dysplasia, among others. CONCLUSION The ATR-X child in this study exhibit a range of clinical phenotypes, including delayed growth and development, facial malformation, abnormal genital appearance, apnea, vomiting symptoms, among others. The de novo variant of ATRX gene c.668G>A (p.C223Y) was identified as the genetic etiology. This study contributes to the expansion of the clinical phenotype spectrum and genetic variation spectrum of ATR-X children.

OBJECTIVE: To investigate the clinical phenotypes and genetic variant characteristics in children with epilepsy. METHODS: A total of 91 children with epilepsy admitted to the Women's and Children's Hospital Affiliated to Ningbo University from July 2021 to October 2022 were selected as the study subjects. Peripheral blood samples were collected from the children for whole exome sequencing. Candidate genetic variants were validated by Sanger sequencing and copy number variation sequencing (CNV-seq). The clinical phenotypes and treatment outcomes of the children with epilepsy were followed up, and an analysis of the relationship between genotype and phenotype was conducted. This study was approved by the Women's and Children's Hospital Affiliated to Ningbo University (Ethics No.: EC2020-048). RESULTS: Among the 91 children with epilepsy, 21 cases (23.08%, 21/91) were found to carry pathogenic or likely pathogenic variants. Of these, 18 cases had involved single base variant or insertional deletion, while 3 cases involved copy number variations. The gene with the highest detection rate was PRRT2 (38.10%, 8/21). Among the children with genetic variants, 47.62% (10/21) had onset during infancy, with 8 diagnosed with Benign familial infantile epilepsy (BFIE), 8 with Developmental epileptic encephalopathy (DEE), and 3 with Epileptic encephalopathy (EE). One case of Dravet syndrome (DS) and one case of Infantile spasms (IS) were also noted. The clinical manifestations of children were diverse and primarily included generalized tonic-clonic seizures and focal seizures. Among them, 52.38% (11/21) had exhibited cluster seizures, 23.81% (5/21) showed fever sensitivity, and 14.29% (3/21) experienced status epilepticus. After pharmacological treatment, 42.86% (9/21) of children had achieved complete seizure control, while 61.90% (13/21) had intellectual disability and 19.05% (4/21) had co-morbid autism spectrum disorder. CONCLUSION Pathogenic or likely pathogenic variants were identified in 23.08% of the pediatric epilepsy cases, with the PRRT2 gene being the most frequently involved. Among children carrying genetic variants, 47.62% had seizure onset during infancy. Genetic factors are an important cause of epilepsy, and early genetic testing may facilitate precise diagnosis, treatment, and prognostic evaluation.
