In this paper， by referring to ancient and modern literature， the textual research of Inulae Flos has been conducted to clarify the name， origin， production area， quality evaluation， harvesting， processing and others， so as to provide reference and basis for the development and utilization of famous classical formulas containing this herb. After textual research， it could be verified that the medicinal use of Inulae Flos was first recorded in Shennong Bencaojing of the Han dynasty. In successive dynasties， Xuanfuhua has been taken as the official name， and it also has other alternative names such as Jinfeicao， Daogeng and Jinqianhua. The period before the Song and Yuan dynasties， the main origin of Inulae Flos was the Asteraceae plant Inula japonica， and from the Ming and Qing dynasties to the present， I. japonica and I. britannica are the primary source. In addition to the dominant basal species， there are also regional species such as I. linariifolia， I. helianthus-aquatili， and I. hupehensis. The earliest recorded production areas in ancient times were Henan， Hubei and other places， and the literature records that it has been distributed throughout the country since modern times. The medicinal part is its flower， the harvesting and processing method recorded in the past dynasties is mainly harvested in the fifth and ninth lunar months， and dried in the sun， and the modern harvesting is mostly harvested in summer and autumn when the flowers bloom， in order to remove impurities， dry in the shade or dry in the sun. In addition， the roots， whole herbs and aerial parts are used as medicinal materials. In ancient times， there were no records about the quality of Inulae Flos， and in modern times， it is generally believed that the quality of complete flower structure， small receptacles， large blooms， yellow petals， long filaments， many fluffs， no fragments， and no branches is better. Ancient processing methods primarily involved cleaning， steaming， and sun-drying， supplemented by techniques such as boiling， roasting， burning， simmering， stir-frying， and honey-processing. Modern processing focuses mainly on cleaning the stems and leaves before use. Regarding the medicinal properties， ancient texts describe it as salty and sweet in taste， slightly warm in nature， and mildly toxic. Modern studies characterize it as bitter， pungent， and salty in taste， with a slightly warm nature. Its therapeutic effects remain consistent across eras， including descending Qi， resolving phlegm， promoting diuresis， and stopping vomiting. Based on the research results， it is recommended that when developing famous classical formulas containing Inulae Flos， either I. japonica or I. britannica should be used as the medicinal source. Processing methods should follow formula requirements， where no processing instructions are specified， the raw products may be used after cleaning.

The transmembrane protein gene family(TMEM)refers to a group of genes that encode trans-membrane proteins.The TMEM family influences tumor angiogenesis by affecting key signaling pathways involved in angiogen-esis,modulating the interactions between tumor cells and endothelial cells and regulating the expression or function of VEGF and its receptor VEGFR.Thereby it may have impact on tumor blood vessel formation.Additionally,the TMEM family regulates mechanisms such as post-translational modifications of histone,which also play a role in tumor initiation and progression.Post-translational modifications of TMEM proteins including phosphorylation,gly-cosylation,acetylation and palmitoylation.TMEM family contributes to tumorigenesis and may identify some novo targets used in precise medical treatment.

Objective:To analyze the correlation between serum leptin (LEP), adiponectin (ADP) levels and bone metabolism indexes in pregnant GDM women complicated with osteoporosis.Methods:A total of 120 GDM patients admitted to our hospital from Dec. 2020 to Dec. 2023 were included as the observation group, and 30 healthy pregnant women were chosen as the control group. The levels of serum LEP, ADP, bone metabolism indexes [parathyroid hormone (PTH), alkaline phosphatase (ALP), 25-hydroxyvitamin D, amino terminal and middle osteocalcin (N-MID) ] were compared. The relationship between serum LEP, ADP and PTH, ALP, 25-hydroxyvitamin D and N-MID was analyzed by Pearson correlation, and receiver operating characteristic curve (ROC) was drawn to evaluate the diagnostic value of serum LEP and ADP levels in gestational diabetes mellitus complicated with osteoporosis.Results:The observation group had higher LEP level, but lower ADP, PTH, 25-hydroxyvitamin D and N-MID level ( t=10.08, 7.19, 12.70, 15.05, 20.54, P<0.05), and there was no significant difference in ALP between the two groups ( t=0.78, P>0.05) ; 25 had osteoporosis and 95 did not. LEP levels in the osteoporosis subgroup were significantly higher than those in the non-osteoporosis subgroup, and ADP, PTH, 25-hydroxyvitamin D and N-MID levels were significantly lower ( t=4.44, 3.06, 3.51, 3.18, 3.00, P<0.05). There was no significant difference in ALP level between the two groups ( t=0.38, P>0.05). Pearson correlation analysis showed that serum LEP and ADP were significantly correlated with PTH, 25-hydroxyvitamin D and N-MID in pregnant GDM women ( P<0.05). The area under the curve (AUC) of serum LEP, ADP and combined test in pregnant GDM women complicated with osteoporosis were 0.723, 0.650 and 0.755, respectively. Conclusion:Serum LEP level increases and ADP level decreases significantly in pregnant GDM women complicated with osteoporosis, which is closely related to bone metabolism indexes, and can assist in early diagnosis of gestational diabetes mellitus complicated with osteoporosis.

OBJECTIVE: To identify the pathogenic variant for a husband with osteogenesis imperfecta and provide preimplantation genetic testing (PGT) for the couple. METHODS: High-throughput sequencing and Sanger sequencing were carried out to identify the pathologic variant in the husband patients. PGT of embryos was performed through direct detection of the mutation site. Meanwhile, chromosome aneuploidy of the blastocysts was screened. Following transplantation, cytogenetic and genetic testing of fetal amniotic fluid sample was carried out during mid-pregnancy. Chromosome copy number variant (CNV) was detected at multiple sites of the placenta after delivery. RESULTS: The husband was found to harbor heterozygous c.544-2A>G variant of the COL1A1 gene. The same variant was not detected in either of his parents. PGT revealed that out of three embryos of the couple, one was wild-type for the c.544-2A site but mosaicism for duplication of 16p13.3.11.2. The other two embryos were both heterozygous for the c.544-2A>G variant. Following adequate genetic counseling, the wild-type embryo was transplanted. Amniotic fluid testing confirmed that the fetus had normal chromosomes and did not carry the c.544-2A>G variant. The copy number of chromosomes at different parts of placenta was normal after birth. CONCLUSION For couples affected with monogenic disorders, e.g., osteogenesis imperfecta, direct detection of the mutation site may be used for PGT after identifying the pathogenic variant. After adequate genetic counseling, prenatal diagnosis must be carried out to ensure the result.

【Objective】 To evaluate the association between prophylactic plasma transfusion and postoperative bleeding rate in critically ill patients undergoing different invasive procedures. 【Methods】 The information of ICU patients who received different invasive procedures from January 2019 to December 2019 in 6 tertiary hospitals in China were retrospectively investigated. The inclusion criteria of patients were as follows: age ≥ 18 years; received invasive procedures; INR ≥ 1.5 within 72 hours before surgery. Exclusion criteria were patients with incomplete case records. The patients finally included in the study were divided into prophylactic plasma transfusion group and non-prophylactic plasma transfusion group according to their plasma transfusion status. The outcome variable was the incidence of invasive procedure-related bleeding within 48 hours after different invasive procedures. 【Results】 A total of 407 patients underwent invasive procedures, and 362 patients were finally included in this study after excluding 45 patients with incomplete case records. The proportions of prophylactic plasma transfusion in different types of invasive procedures were central venous catheterization (46/146, 31.5%), thoracentesis (13/37, 35.1%), bronchoscopy (8/31, 25.8%), tracheal intubation (9/38, 23.7%), arterial catheterization (9/50, 18.0%) and others (13/60, 21.7%). The bleeding rates showed that different invasive procedures presented no statistical difference between the groups received plasma transfusion or not. In the prophylactic plasma transfusion group, the bleeding rate of arterial catheterization (4/9, 44.4%) was the highest, but all were potential bleeding, followed by tracheal intubation (4/10, 40.0%) and central venous intubation (16/46, 34.8%), with a higher rate of significant bleeding. 【Conclusion】 Prophylactic infusion of plasma did not reduce the bleeding rate after different invasive procedures, but prospective studies are needed to further confirm the conclusion; this study also provides a certain data basis for later prospective studies.

【Objective】 To investigate the risk factors of vasovagal reactions(VVR) related to plasma donation, so as to put forward clinical suggestions for early identification and accurate intervention of high-risk groups to ensure the safety of plasma donation. 【Methods】 The demographic characteristics(i.e. gender, age, weight) and records of plasma donors(donation history, pulse before plasma donation, duration of collection, etc.) were collected from July to December 2019 in a region of Sichuan. Based on logistic regression analysis, the correlation between these factors and the risk of VVR was explored. 【Results】 The information of 69 172 donors was collected, and the incidence of VVR was 7.04‰. The risk of VVR was reduced by 99% in the group with plasma collection duration less than 30 minutes compared with the group with plasma collection duration more than 50 minutes(OR, 0.01; 95% CI, 0.00~0.01; P<0.001). The risk of male group was 94 % lower than that of female group(OR, 0.06; 95% CI, 0.04~0.10; P<0.001). Compared with the 45~50 kg group, the risk of weight greater than 80 kg group decreased by 80%(OR, 0.20; 95% CI, 0.09~0.42; P<0.001). The risk of repeated donation group was 34 % lower than that of the first time donation group(OR, 0.66; 95% CI, 0.47~0.91; P<0.001). The risk of VVR in the group with pulse greater than 90 bpm before plasma donation was 2.43 times that in the 60~69 bmp group(OR, 2.43; 95% CI, 1.75~3.36; P<0.001). 【Conclusion】 Duration of plasma collection, gender, weight, frequency of plasma donation, pulse before plasma donation and donor status are independent risk factors for plasma donation-related VVR. Among them, plasma collection duration, gender and weight were the main independent risk factors for plasma donation-related VVR. For donors with plasma collection duration more than 50 minutes, female and low weight, higher risk of VVR was presented and more preventive intervention should be given.

OBJECTIVE: To carry out genetic testing for an abortus suspected with Cornelia de Lange syndrome (CdLS). METHODS: History of gestation and the family was taken. Combined with prenatal ultrasonography and the phenotype of the abortus, a diagnosis was made for the proband. Fetal tissue and peripheral blood samples of its parents were collected for the extraction of genomic DNA. Whole exome sequencing was carried out to detect mutations related to the phenotype. Suspected mutations were verified in the parents through Sanger sequencing. RESULTS: Prenatal ultrasound found that the forearms and hands of the fetus were anomalous, in addition with poorly formed vermis cerebellum, slight micrognathia, and increased echo of bilateral renal parenchyma. Examination of the abortus has noted upper limb and facial malformations. Whole exome sequencing revealed that the fetus carried a heterozygous c.2118delG (p.Lys706fs) frameshift mutation of the NIPBL gene. The same mutation was not found in either parent. CONCLUSION The heterozygous c.2118delG (p.Lys706fs) frameshift mutation of the NIPBL gene probably underlies the CdLS in the fetus. Above finding has provided a basis for the genetic counseling for the family.

OBJECTIVE: To apply nanopore third-generation sequencing for the detection of chromosomal aneuploidy samples, and explore its performance and application prospects. METHODS: DNA extracted from two human cell lines with X chromosome monosomy and 22.5 Mb deletion in 7q11.23-q21.3 region was sequenced with a MinION sequencer, and the results were analyzed. RESULTS: Respectively, 555 872 and 2 679 882 reads were obtained from the two samples within 24 hours, with genome coverage being 53.75% and 88.63%. With a sequencing depth of 0.81× and 2.40× , respectively, the abnormal chromosomal regions could be detected by comparative analysis using Minimap2. CONCLUSION With low-depth whole genome sequencing, the use of nanopore third-generation sequencing is expected to complete the detection and analysis of chromosomal aneuploidy samples within 24 hours, but its further application and promotion needs to overcome the cost constraints.

Since the establishment of the voluntary blood donation system, the rate of voluntary blood donation in China has increased significantly. But in recent years, blood donation has entered a period of slow growth, while the demand for clinical blood continues to increase, resulting in a seasonal and periodic shortage of blood. Various incentives have been used to promote blood donation in order to ensure the supply of blood for clinical use. However, the actual effectiveness of incentives to promote blood donation is unclear. This article aims to analyze the advances in incentives of voluntary blood donation, and discuss the existing problems, in order to lay a foundation for further research on more economical and effective promotion measures to establish a more perfect promotion measures management system.
