Cornelia de Lange syndrome is a rare congenital malformation disease,and its typical features include growth restriction,mental retardation,craniofacial abnormality and hirsutism.This study reported 2 cases of CdLS patients,summarized their clinical manifestations and gene mutation characteristics,and the relevant literatures were reviewed.Patient 1,a 5-year-old girl,was admitted to the hospital due to growth retardation.Physical examination revealed hirsutism,monobrow,small and sparse teeth,hemangiomas(approximately 2 cm×2 cm)on the chest and back,delayed language development,and intellectual disability.The height was 98 cm[≤-2 standard deviation(SD)],the weight was 15 kg(-2SD--1SD),the head circumference was 46 cm(-3SD--2SD).Brain magnetic resonance imaging(MRI)plain scan showed slightly enlarged left lateral ventricle and bilateral lateral ventricle triangles,slightly thickened bilateral maxillary sinus and ethmoid sinus mucosa.Echocardiography revealed mild regurgitation of the mitral and tricuspid valves.Patient 2,a 1-month-old girl,was admitted to the hospital due to postpartum shortness of breath.The physical examination highlighted hirsutism,short nose,soft cleft palate,dysphagia,positive three-concave sign,audible throat sound,small hands,palm penetration in the left hand,short fifth finger of the right hand,limited right hip abduction,foot varus,and a white spot at the bottom of the right eye.Ultrasonography at 1 month showed mild regurgitation of the tricuspid valve and an open foramen ovale.Brain MRI at 2 d showed a few patchy low-signal shadows in the longitudinal fissure cistern and tentorium,a small amount of subarachnoid hemorrhage,and a small amount of fluid in the bilateral maxillary sinus,ethmoid sinus,and middle ear mastoid.No obvious structural or numerical abnormalities were observed in the chromosome karyotypes.Whole-exome sequencing detected a heterozygous variation of c.6653_6655del in the NIPBL gene in patient 1 and a heterozygous variation of c.337C＞T in the NIPBL gene in patient 2.These variations were not found in their parents.The study revealed that NIPBL gene variation could be the genetic cause of the two patients with CdLS.The identification of the variation c.337C＞T may expand the variation spectrum of the NIPBL gene,providing valuable insights into the pathogenic genetic basis of CdLS.

Objective To observe the clinical efficacy of Fangxiang Wentong Powder(composed of Salviae Miltiorrhizae Radix et Rhizoma,Chuanxiong Rhizoma,Alpiniae Officinarum Rhizoma,Piper Longum,and Corydalis Rhizoma)acupoint application combined with Kuanxiong Aerosol in treating female patients with coronary slow flow(CSF)associated angina.Methods After sample size estimation,119 female inpatients diagnosed as CSF associated angina and differentiated as chest-qi obstruction with yang deficiency and cold accumulation syndrome of traditional Chinese medicine(TCM)were collected from the cardiovascular departments of the Third People's Hospital of Fujian University of Traditional Chinese Medicine,the Second Affiliated Hospital of Guangzhou University of Chinese Medicine(Guangdong Provincial Hospital of Chinese Medicine),Zhanjiang First Traditional Chinese Medicine Hospital,and Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from November 2023 to March 2024.Using a table of random numbers,the patients were divided into a treatment group(84 cases)and a control group(35 cases)in a ratio of 5∶2.The control group was treated with Isosorbide Monomitrate Sustained-Release Capsules,while the treatment group was treated with application of Fangxiang Wentong Powder on acupoints of Danzhong(CV17),Gaohuang(BL43),and Xinshu(BL15),together with sublingual administration of Kuanxiong Aerosol.The treatment course for both groups covered 7 days.Before and after treatment,the changes in the simplified Seattle Angina Questionnaire(SAQ-7)scores,Chinese Quality of Life Questionnaire for Cardiovascular Patients(CQQC)scores,6-minute walking distance(6MWD),serum C-reactive protein(CRP)level,and white blood cell-to-mean platelet volume ratio(WMR)were observed.The TCM symptom efficacy was compared between the two groups,and adverse reactions were monitored.Results(1)There were 8 patients withdrew in the treatment group for failing in completing the questionnaires,and 2 patients withdrew in the control group for suffering headaches after taking nitrates.Eventually,109 patients completed the trial,including 76 in the treatment group and 33 in the control group.(2)After 7 days of treatment,the total effective rate for TCM symptom efficacy in the treatment group was 86.84%(66/76),and that in the control group was 72.73%(24/33).The intergroup comparison(tested by the chi-square test)showed that the TCM symptom efficacy in the treatment group was significantly superior to that in the control group.(3)After treatment,both groups showed improvements in the scores of activity limitation and angina frequency items of SAQ-7,and the treatment group also showed improvements in the scores of subjective satisfaction item of SAQ-7(P＜0.05).The treatment group's improvements in the scores of activity limitation,angina frequency,and subjective satisfaction items of SAQ-7 were significantly superior to those of the control group(P＜0.05).(4)After treatment,the CQQC scores in the treatment group was significantly improved(P＜0.05),while no significant improvement was observed in the control group(P＞0.05).The improvement of CQQC scores in the treatment group was significantly superior to that in the control group(P＜0.05).(5)After treatment,both groups showed improvements in 6MWD(P＜0.05),and the improvement in the treatment group was significantly superior to that in the control group(P＜0.05).(6)After treatment,the serum levels of inflammatory indicators of CRP and WMR in the treatment group were significantly improved(P＜0.05),while no significant improvements were presented in the control group(P＞0.05).The improvements in serum CRP level and WMR value in the treatment group were significantly superior to those in the control group(P＜0.05).(7)No adverse reactions were found in the treatment group,indicating high safety.Conclusion Fangxiang Wentong Powder acupoint application combined with Kuanxiong Aerosol is more effective than Isosorbide Monomitrate Sustained-Release Capsules,improving exercise tolerance,decreasing inflammatory factor levels,and improving the quality of life to some extent during the treatment of female patients with CSF.

Objective To observe the clinical efficacy and safety of external application of Piyan Formula in treating epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKIs)-related rashes.Methods Sixty cases of EGFR-TKIs-related rash patients were randomly allocated into either a treatment group or a control group.The treatment group received external application of Piyan Formula to the rash area twice daily for 14 days.The control group received external application of fucidic acid cream to the rash area twice daily for 14 days.Changes in rash grading,itching grading,quality of life scores and adverse event were observed and recorded in both groups.At the same time,levels of hypersensitive C-reactive protein,interleukin(IL)-6,and IL-1β were measured before treatment and 24 hours after treatment.Results After treatment,the rash severity,itching severity,and quality of life scores were notably lower in the treatment group compared to the control group(P<0.05).The levels of hypersensitive C-reactive protein,IL-6,and IL-1β exhibited a significant decrease compared to their pre-treatment values.(P<0.05).Compared with the control group,the levels of hypersensitive C-reactive protein,IL-6,and IL-1β decreased in the treatment group,with statistically significant differences(P<0.05).No adverse events related to Piyan Formula or fucidic acid cream occurred during the treatment process.Conclusion External application of Piyan Formula in treating EGFR-TKIs-related rashes shows significant clinical efficacy,can effectively reduce the levels of inflammatory factors,and has high safety,thus warranting clinical promotion.

Objective:To explore the key genes related to the development, progression and prognosis of acute myeloid leukemia (AML) based on bioinformatics, and to analyze their functions.Methods:The chip expression profile GSE84881 data set of AML patients including 19 AML samples and 4 normal tissue samples was downloaded from the gene expression omnibus (GEO) database. GEO online tool GEO2R was used to screen the differentially expressed genes (DEG). The DAVID online database was used to make gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) enrichment analysis of DEG. The STRING online database was used to analyze the protein interaction (PPI) network of DEG, and the key genes were screened by using the Cytoscape software. The weighted gene co-expression network analysis (WGCNA) was used to build co-expressed network and obtain the central genes.LC-Bio online platform was used to construct Venn diagram and the key genes and central genes in PPI were crossed to finally obtain the true key genes. RNA-seq datasets GSE2191 and GSE90062 of human tissues were downloaded from GEO database to verify the screened key genes. Kaplan-Meier method was used to analyze the effects of key genes on the overall survival (OS) of AML based on the data of GEPIA database.Results:A total of 247 DEG were identified in GSE84881 data set, including 112 up-regulated genes and 135 down-regulated genes. According to the results of GO enrichment analysis, 247 DEG were mainly enriched in the regulation of signal transduction and cell proliferation in the biological process (BP); the cell composition (CC) revealed that these genes were mainly involved in the cytoplasm and exosomes; the molecular function (MF) analysis showed that these genes were mainly enriched in protein binding and calcium binding. Further KEGG pathway enrichment analysis showed that these 247 DEG were mainly involved in NOD-like receptor signal pathway and interleukin 17 (IL-17) signal pathway. And then the 12 key genes were obtained from PPI. WGCNA software was used to screen 13 central genes from GSE84881 dataset and finally 1 real key gene EGF was obtained after taking intersection. Kaplan-Meier method showed that OS time of AML patients in EGF high expression group was decreased than that in EGF low expression group, and the difference was statistically significant( P = 0.044). Conclusions:EGF may be an important diagnosis and treatment target of AML and may become a potential biomarker for clinical treatment and prognosis prediction of AML.

The clinical data of a child with chemical pneumonia caused by kerosene in Hainan Maternal and Children′s Medical Center in June 2019 were retrospectively analyzed.The patient was a 2 years and 1 month old boy with a history of kerosene inhalation and fever.The clinical features included low breath sounds in the left lung and dry and wet rales in both lungs.The white blood cells (WBC) level, C-reactive protein (CRP) level, and erythrocyte se-dimentation rate (ESR) were significantly increased.Chest CT showed inhalation pneumonia.Chest ultrasound suggested medium pleural effusion on the left side.The patient was given antibiotics, nebulization and other treatment.On the 12 th day of the course of the disease, his temperature returned to normal, and breath sounds on the left side were stronger than before.The WBC level, CRP level and ESR were improved according to the re-check results, but pulmonary ventilation was still obstructed mildly to moderately.Fourteen days after hospital discharge, the patient coughed less.Reexamination of chest CT prompted the lesions were further absorbed, but the mild to moderate obstructive lesions were still observed.With the reduction of kerosene use in daily life, kerosene-induced chemical pneumonia is rare, but due to its diverse and complex clinical manifestations and slow absorption of pulmonary inflammation, attention should be paid to its progression into chronic cough.

OBJECTIVE To compare the costeffectiveness of two surgical approaches:endoscopic silicone tube intubation(ESTI) and conventional blind silicone tube intubation(CBSTI),in the management of chronic dacryocystitis(CDC).METHODS There were 46 cases of CDC from the Third Affiliated Hospital of Sun Yat-sen University from 2014 to 2015.Randomly,22 CDC patients were included in ESTI,24 patients were performed CBSTI.We analyzed both the final success rate,operating time,intraoperative visual analogue scale(VAS) and the rate of post-operative complications,as well as the final therapeutic effect.RESULTS In ESTI group,17 cases were cured,5 cases were improved and 3 cases were invalid.The success rate was 88.00％.Correspondingly for CBSTI group,14 cases were cured,6 eases were improved and 5 cases were invalid,and the success rate was 80.00％.ESTI was better,but there was no significant in success rate between the two groups (x2=0.881,P=0.644).Besides,the operating time and intraoperative VAS score in ESTI group was (10.32±2.30)min and 2.02±0.86,and they were(25.32 ± 4.87)min and 4.11 ± 1.44 in CBSTI group.So ESTI was better than CBSTI(t=-13.918,P=0.000;t=-6.012,P=0.000).ESTI had fewer complications(x2=4.878,P=0.027).CONCLUSION Compared to CBSTI,ESTI is a minimally invasive and highly effective technique for the treatment of CDC.The visualization of nasal endoscopy is the optimization of CBSTI,and this method need to be popularization and application.
