Two pediatric heart failure patients were treated with pulmonary artery banding(PAB)at Fuwai Hospital,from December 2021 to January 2022.In the first case,an 8-month-old patient presented with left ventricular non-compaction cardiomyopathy(LVNC),left ventricular systolic dysfunction,ventricular septal defect,and atrial septal defect.The second case was a 4-month-old patient with LVNC,left ventricular systolic dysfunction,and coarctation of the aorta.After PAB,the left ventricular function and shape of both patients were significantly improved,without serious surgery-related complications.In these individual cases of pediatric heart failure,pulmonary artery banding exhibited a more satisfactory efficacy and safety compared to pharmacological treatment,especially for those with unsatisfactory medication results.Future clinical data are needed to promote the rational and broader application of this therapeutic option for indicated patients.

Berberine is an antipyretic and detoxicating drug commonly used in clinical practice,and it is currently used for the routine treatment of gastrointestinal diseases such as bacterial gastroenteritis and diarrhea.However,several recent studies have shown that berberine can exert a therapeutic effect on the diseases such as autoimmune hepatitis,viral hepatitis,nonalcoholic fatty liver disease,and liver cancer by regulating the AMPK and TGF-β pathways and altering the composition of intestinal flora.This provides new drugs for the treatment of these diseases,expands the potential indications of berberine,and provides clues for the follow-up research and development of similar drugs.This article summarizes the therapeutic effect and mechanism of berberine on various liver diseases,in order to provide a reference for effective clinical application.

Objective:Migraine and tremor share some genetic mutation sites,and clinical studies have also confirmed their correlation.This study aims to explore the clinical and electrophysiological characteristics of migraine patients with concomitant tremor,and to analyze the relevant influential factors of tremor occurrence. Methods:We retrospectively analyzed the clinical data of 217 migraine patients who visited the Third Affiliated Hospital of Qiqihar Medical University from June 2022 to October 2023.The Clinical Rating Scale for Tremor(CRST),Numerical Rating Scale(NRS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9)were respectively used to assess the tremor symptoms,degree of headache,anxiety,and depression of patients.All patients underwent routine head MR scanning and electromyography examination,and were divided into a migraine with tremor group and a migraine without tremor group based on the electromyogram examination. Results:The migraine with tremor group and the migraine without tremor group were included 52 patients(23.96%)and 165 patients(76.04%),respectively.Compared with the migraine without tremor group,the migraine with tremor group had a longer course and duration of headache,higher frequency of headache attacks,higher NRS score,GAD-7 score,and PHQ-9 score,and fewer weekly physical exercises.The differences were statistically significant(all P<0.05).There were no statistically significant differences in the presence or absence of prodromal headache and white matter hyperintensities(WMHs)between the 2 groups(both P>0.05).The evaluation results of the CRST showed that out of 217 migraine patients,39 patients(17.97%)were accompanied by tremors.The electromyographic results showed that all 52 migraine patients with tremors had upper limb tremors,including 28 migraine patients with postural tremors and 24 migraine patients with static tremors.Compared with the migraine patients with static tremors,the migraine patients with postural tremors had lower average frequency,peak frequency,and headache onset frequency(all P<0.05).Multiple linear regression analysis showed that frequency of physical exercise,duration of illness,frequency of headache attacks,NRS score,GAD-7 score,and PHQ-9 score were risk factors for migraine patients with concomitant tremors(all P<0.05). Conclusion:Patients with migraine mainly experience upper limb postural tremors.Reduced physical exercise,long course of disease,long duration of headache,frequent headache attacks,severe headache,anxiety,and depression are risk factors for migraine patients with concomitant tremors.

This article reported the genetic analysis of a case diagnosed with fetal micrognathia and cleft palate by mid-trimester ultrasound in two consecutive pregnancies. In the first pregnancy, the pregnant woman delivered a full-term boy transvaginally, who died two weeks after birth and was diagnosed with Pierre Robin sequence (PRS). Chromosome karyotype and genomic copy number variation. In the second pregnancy, the woman underwent amniocentesis due to suspected PRS presenting by fetal cleft palate, micrognathism, and additional ultrasound anomalies. No abnormalities were detected in fetal karyotype or genomic copy number variation. Whole-exome sequencing, bioinformatics analysis, and Sanger sequencing suggested that both the fetus and the firstborn boy inherited a possible pathogenic variant of c.79delG p.E27Sfs*24 in the BMP2 gene from the mother. The pregnancy was terminated after the genetic consultation. Fetal phenotypes in the two fetuses were similar, indicating that short stature, facial dysmorphism, and skeletal anomalies with or without cardiac anomaly in the pedigree were caused by the heterozygous variant of c.79delG p.E27Sfs*24 in the BMP2 gene.

Gallstone disease is a common and frequently seen disease of digestive system, and is a common cause of inflammation of gallbladder and bile duct, biliary tract tumor and obstructive jaundice, however, its pathogenesis is not yet fully understood. Recent studies have revealed that intestinal flora and immunity play important roles in the formation of gallstones. This paper reviewed the relationship between the abundance and composition of intestinal flora, immuno - globulins, mucins and immune cells, as well as the interactions between intestinal flora and biliary immunity and gallstone formation for providing new ideas and methods for gallstone prevention and treatment.

Objective:To examine whether the mixed infection rate in pertussis infants is significantly higher than that in non-pertussis infants with respiratory tract infection, to explore the mixed infection pathogen distribution in pertussis infants, and to provide reference for clinical diagnosis and treatment.Methods:A case-control study was conducted on 118 nasopharyngeal swabs collected from infants who applied for clinical pertussis etiological testing (culture and specific nucleic acid detection of Bordetella pertussis) in Beijing Children′s Hospital, Jiaxing Maternity and Child Health Care Hospital and Wuhu No.1 People′s Hospital from August 2018 to January 2021.According to the pertussis etiological testing results, the patients were divided into the pertussis group (65 cases) and non-pertussis group (53 cases). Thirty-three pairs of cases were matched according to age, onset season and city.All nasopharyngeal swabs were tested for infections of other pathogens using FilmArray RP2, which can detect 21 respiratory infection pathogens.The mixed infection rate was compared between groups by Chi- square test. Results:According to the FilmArray RP2 test results, 56.9%(37/65) cases in pertussis group and 15.1%(8/53) cases in the non-pertussis group were positive for multiple pathogens, and the difference was statistically significant ( χ2=21.651, P<0.001). The top 5 mixed infection pathogens in pertussis infants were human rhinovirus/enterovirus (HRV/EV) (38.5%, 25/65), parainfluenza virus (PIV) (18.5%, 12/65), respiratory syncytial virus (RSV) (10.8%, 7/65), coronavirus (Cov) (10.8%, 7/65), and adenovirus (ADV) (7.7%, 5/65). The mixed infection rates of the pertussis group in spring, summer, autumn and winter were 46.2% (6/13), 58.3%(14/24), 55.6%(5/9), and 63.2%(12/19), respectively.Comparison of matched and unmatched cases achieved similar results. Conclusions:Among clinical suspected pertussis infant specimens, the mixed infection rate in confirmed cases is tremendously higher than that in non-pertussis infants.The main mixed infection pathogens in pertussis infants are HRV/EV, PIV, RSV, Cov, and ADV.Mixed infection in pertussis children commonly occurs in four seasons, with the highest incidence in winter.

OBJECTIVE: To assess the value of copy number variations (CNVs) and chromosomal karyotyping analysis for patients with intellectual disability/developmental delay (ID/DD). METHODS: Chromosomal karyotype analysis was applied to 530 children diagnosed with ID/DD. Single nucleotide polymorphism array (SNP-array) was further applied for 120 children with unknown etiology. RESULTS: Among the 530 children with ID/DD, 104 (19.62%) were detected with chromosomal abnormalities. For the 120 children analyzed by SNP-array, 44 (36.67%) were detected with CNVs, among which 20 were predicted as pathogenic, 6 as likely pathogenic, 10 as variants of unknown significance, 7 as likely benign,and 1 as loss of heterozygosity. CONCLUSION SNP-array can facilitate delineation of the etiology of patients with ID/DD, which may provide a basis for their prognosis, consultation and clinical intervention.

Objective To observe the regulation of Panx1 on ATP/IP3 signaling pathway and its mechanism during cisplatin-induced apoptosis of lung adenocarcinoma cells. Methods Human lung adenocarcinoma cell line A549 was used as the research object and carbenoxolone (CBX) was used as a drug interference tool. A549 cells were divided into normal control group, the CBX group, the cisplatin (DDP) group and the CBX+DDP group. MTT assay and Annexin V/PI assay were used to detect the survival and apoptosis rates of A549 cells. The relative concentrations of extracellular adenosine triphosphate (ATP) and intracellular inositol triphosphate (IP3) were measured by Chemiluminescence and ELISA. Results Compared with DDP group, the cell survival rate of CBX+DDP group increased, while the early and late apoptotic rates and the release concentration of extracellular ATP and intracellular IP3 decreased (all P < 0.01). Conclusion Panx1 can increase the sensitivity of lung adenocarcinoma cells to cisplatin by regulating the ATP/IP3 signaling pathway.

Objective To investigate the ratio of transfer cesarean section after trial of labor and maternal-fetal outcomes based on Robson classifications.Methods The delivery data by cesarean section in Third Affiliated Hospital of Guangzhou Medical University from January 1st,2009 to December 31st,2015 (gestational age ＞28 weeks and newborn birth weight ＞1 000 g) were retrospectively collected.The ratio of transfer cesarean section after trial of labor and maternal-fetal adverse outcomes were analyzed by weighted adverse outcome score in different Robson classifications.Results (1) The highest ratio of transfer cesarean section after trial of labor was classification 9 (all abnormal lies,including previous cesarean section and breech were excluded) reached 47.31％ (431/911),followed by classification 2 (nulliparous women with a single cephalic pregnancy,＞37 weeks gestation who had labour induced) accounted for 44.90％(409/911).(2)The tops of weighted adverse outcome score of transfer cesarean section after trial of labor were classification 10 (single cephalic pregnancy at ＜37 weeks gestation,including women with previous cesarean delivery) 24.55,classification 5 (single cephalic pregnancy multiparous women,with at least one previous cesarean delivery,＞37weeks gestation) 3.64.Conclusion Carefully evaluating the delivery mode and emphasizing the intrapartum management in nulliparous women with a single cephalic pregnancy,at ＞ 37 weeks gestation who had labour induced and trial of labor after cesarean section is essential to reduce the risk of adverse outcomes in transfer cesarean section after trial of labor.

Metastasis is the leading cause of human cancer deaths. Unfortunately, no approved drugs are available for anti-metastatic treatment. In our study, high-throughput sequencing-based high-throughput screening (HTS) and a breast cancer lung metastasis (BCLM)-associated gene signature were combined to discover anti-metastatic drugs. After screening of thousands of compounds, we identified Ponatinib as a BCLM inhibitor. Ponatinib significantly inhibited the migration and mammosphere formation of breast cancer cells in vitro and blocked BCLM in multiple mouse models. Mechanistically, Ponatinib represses the expression of BCLM-associated genes mainly through the ERK/c-Jun signaling pathway by inhibiting the transcription of JUN and accelerating the degradation of c-Jun protein. Notably, JUN expression levels were positively correlated with BCLM-associated gene expression and lung metastases in breast cancer patients. Collectively, we established a novel approach for the discovery of anti-metastatic drugs, identified Ponatinib as a new drug to inhibit BCLM and revealed c-Jun as a crucial factor and potential drug target for BCLM. Our study may facilitate the therapeutic treatment of BCLM as well as other metastases.
