Objective To mine the adverse drug events(ADE)signal of avatrombopag,an effective drug for thrombocytopenia treatment,based on real world data in order to provide reference for its clinical safety application.Methods The OpenVigil2.1 pharmacovigilance platform was used to obtain the ADE report data of avatrombopag from May 2018 to March 2023 in the database of FDA adverse event reporting system(FAERS).The ADE signals were classified and described by the system organ class(SOC)and preferred term(PT)of the ADE terminology set in the Medical Dictionary for Regulatory Activities(MedDRA),and reporting odds ratio(ROR)and UK Medicines and Healthcare Products Regulatory Agency(MHRA)comprehensive standard were used to detect the positive ADE signals.Results A total of 1 879 ADE reports related to avatrombopag were obtained,24 SOCs were involved,and 28 positive ADE signals were detected at PT level.Among these signals,the strongest ones were renal vein thrombosis,portal vein thrombosis and graft versus host disease,while the reports accounting for the largest numbers were headache,fatigue and asthenia.There were 8 ADE signals discovered newly,that is,seasonal allergy,back disorder,musculoskeletal discomfort,flatulence,hypersomnia,rash macular,emotional disorder,and rhinorrhoea.Conclusion For clinical use of avatrombopag,clinicians should not only concern the risk of thrombosis,but also pay close attention to ADE signals such as seasonal allergy,back disorder,musculoskeletal discomfort,flatulence,hypersomnia,rash macular,emotional disorder,and rhinorrhoea that are not documented in the instructions.

Objective To analyze the mortality and its changing trend, and composition and order of causes of death of residents in Mengzi City, and to provide a basis for further disease prevention and control. Methods The death causes surveillance data from 2018 to 2021 were derived from the all-cause-of-death surveillance system in Mengzi City. A retrospective analysis was performed on the mortality rate, life expectancy, life expectancy eliminating causes of death, and life loss. The annual percentage change (APC) was analyzed by the Joinpoint regression model to describe changes in mortality trends. Results The overall crude mortality rate was 633.88/100,000. The age-adjusted mortality was 866.87/100,000. There was a significant downward trend in the crude and standardized mortality (APC=-1.73% , APC=-5.96% , P<0.05). Deaths due to chronic non-communicable diseases (NCDs) accounted for 76.44% of the total deaths. The top 5 causes of death of the residents were cerebrovascular diseases (140.38/100 000), heart diseases (104.24/100 000), malignant neoplasms (92.75/100 000), injuries (79.37/100 000), and respiratory diseases (63.17/100 000) in order, accounting for 75.71% of all causes of death. Life expectancy was 75.67 years, 72.32 years and 79.49 years in the whole-population, males and females, respectively. The potential life expectancy loss due to injury, malignant tumor and cerebrovascular disease accounted for 65.45% of all causes of death. Conclusion Chronic non-communicable diseases are the focus of prevention and control work in Mengzi City. Particular attention should be paid to the damage to health and loss of life caused by injuries, malignancies and cerebrovascular diseases.

Objective:To analyze the status of neonatal respiratory distress syndrome (RDS) management in 10 hospitals in Northwest China over the past five years and to investigate the strategies for improving the prevention and treatment of RDS.Methods:This retrospective study involved premature infants with RDS who were admitted to the neonatal intensive care units (NICU) of 10 hospitals (six in Shaanxi Province, three in Gansu Province, and one in Xinjiang Uygur Autonomous Region) of the Northwest China Neonatal Collaborative Group within 3 d after birth from January 1 to December 31, 2016, and from January 1 to December 31, 2021.

Pulmonary blast injury has become the main type of trauma in modern warfare, characterized by externally mild injuries but internally severe injuries, rapid disease progression, and a high rate of early death. The injury is complicated in clinical practice, often with multiple and compound injuries. Currently, there is a lack of effective protective materials, accurate injury detection instrument and portable monitoring and transportation equipment, standardized clinical treatment guidelines in various medical centers, and evidence-based guidelines at home and abroad, resulting in a high mortality in clinlcal practice. Therefore, the Trauma Branch of Chinese Medical Association and the Editorial Committee of Chinese Journal of Trauma organized military and civilian experts in related fields such as thoracic surgery and traumatic surgery to jointly develop the Clinical treatment guideline for pulmonary blast injury ( version 2023) by combining evidence for effectiveness and clinical first-line treatment experience. This guideline provided 16 recommended opinions surrounding definition, characteristics, pre-hospital diagnosis and treatment, and in-hospital treatment of pulmonary blast injury, hoping to provide a basis for the clinical treatment in hospitals at different levels.

The vagina contains at least a billion microbial cells,dominated by lactobacilli.Here we perform metagenomic shotgun sequencing on cervical and fecal samples from a cohort of 516 Chinese women of reproductive age,as well as cervical,fecal,and salivary samples from a second cohort of 632 women.Factors such as pregnancy history,delivery history,cesarean section,and breastfeeding were all more important than menstrual cycle in shaping the microbiome,and such information would be necessary before trying to interpret differences between vagino-cervical micro-biome data.Greater proportion of Bifidobacterium breve was seen with older age at sexual debut.The relative abundance of lactobacilli especially Lactobacillus crispatus was negatively associated with pregnancy history.Potential markers for lack of menstrual regularity,heavy flow,dysmenor-rhea,and contraceptives were also identified.Lactobacilli were rare during breastfeeding or post-menopause.Other features such as mood fluctuations and facial speckles could potentially be predicted from the vagino-cervical microbiome.Gut and salivary microbiomes,plasma vitamins,metals,amino acids,and hormones showed associations with the vagino-cervical microbiome.Our results offer an unprecedented glimpse into the microbiota of the female reproductive tract and call for international collaborations to better understand its long-term health impact other than in the settings of infection or pre-term birth.

TBX20 gene, a member of the T-box gene family, plays an important role during heart development and is required for maintaining adult heart function.TBX20 can act as both transcriptional activator and transcriptional suppressor during the development of the heart, and shows complex spatiotemporal regulation.TBX20 is an important candidate transcription factor for the pathogenesis of congenital heart disease(CHD), and its mutation or expression change can lead to the occurrence of CHD.In this paper, the latest research progress of TBX20 gene in the field of heart development is reviewed from the relationship between TBX20 and CHD, the signaling pathway involved in heart development and its interactions with other cardiac transcription factors.

Vascular cognitive impairment (VCI) is a clinical syndrome with impairment of at least one cognitive domain caused by vascular risk factors or cerebrovascular diseases, and its pathogenesis is not completely clear so far. Microglia are innate immune cells in the brain. They participate in many processes such as neuroinflammation, synaptic pruning, myelin regeneration, neurogenesis and connection. They are associated with the occurrence and development of various neurological diseases such as cerebral infarction, Alzheimer's disease, Parkinson's disease, and autism. Recent studies have shown that microglia play an important role in the development of VCI. This article reviews the role of microglia in VCI.

OBJECTIVE: To diagnose a fetus with Phelan-McDermid syndrome (PMS) using various techniques. METHODS: Single nucleotide polymorphism array (SNP Array), multiplex ligation-dependent probe amplification (MLPA), fluorescence in situ hybridization (FISH) were applied in conjunction for the prenatal diagnosis of the fetus. RESULTS: SNP Array detected a 4.03 Mb microdeletion at 22q13.31q13.33 in the fetus, which was confirmed by FISH and MLPA. FISH analysis of the parents suggested that the 22q13.31q13.33 deletion has a de novo origin. CONCLUSION Combined use of various techniques can enable accurate prenatal diagnosis and genetic counseling.
