To clarify the occurrence and distribution of broad bean wilt virus 2(BBWV2) on Rehmannia glutinosa, this study collected 87 R. glutinosa samples with typical symptoms of viral disease such as chlorosis and crumple from Wenxian county and Wuzhi county in Jiaozuo city, Henan province and Qiaocheng district in Bozhou city, Anhui province. The BBWV2 CP target band was amplified from 37 R. glutinosa samples by RT-PCR technology. The total detection rate reached 42.5%, among which 43.0% was detected in samples from Henan province. The detection rate in samples from Anhui province was 37.5%. 37 BBWV2 CP sequences were obtained by cloning and sequencing of BBWV2 positive samples(data has been submitted to GenBank, accession numbers: PP407959-PP407995), and the sequence analysis of these CP sequences with 91 other BBWV2 isolates in GenBank showed a high genetic diversity with a consistency rate of 70.8%-100%. Meanwhile, phylogenetic analysis showed that BBWV2 could be divided into three groups according to CP sequences, among which the BBWV2 in R. glutinosa isolates obtained in this study were all located in group 3. This study identified the differences in the occurrence, distribution, and genetic diversity of BBWV2 in R. glutinosa from Henan province and Anhui province and provided a theoretical basis for the prevention and control of BBWV2.

Acute myocardial infarction and acute upper gastrointestinal bleeding are both critical internal medicine conditions. The incidence of acute upper gastrointestinal bleeding in patients with acute myocardial infarction ranges from 5.31% to 8.90%, with a mortality rate as high as 20.50% to 35.70%. The pathogenesis may be related to the use of antiplatelet and anticoagulant drugs, as well as stress-induced injury. In treatment, the contradiction between antiplatelet/anticoagulation therapy and bleeding has made this disease a significant challenge in modern medicine. Therefore, re-exploring the etiology, pathogenesis, treatment principles, and methods of traditional Chinese medicine(TCM) for acute myocardial infarction and acute upper gastrointestinal bleeding is of great clinical importance. The research team has been working year-round in the coronary care unit(CCU), managing a large number of such severe patients. By revisiting classic texts and delving into the foundational theories of TCM and historical medical literature, it has been found that this disease falls under the category of "distant blood" in the Synopsis of the Golden Chamber. In terms of etiology, it is primarily associated with weakness of healthy Qi and damage caused by drug toxicity. In terms of pathogenesis, in the acute stage, it mainly manifests as insufficient spleen Yang, deficiency of spleen Qi, and failure of the spleen to control blood. In the remission stage, it is characterized by deficiency of both heart Qi and spleen blood. For treatment, during the acute stage, Huangtu Decoction is used to warm Yang and restrain blood, while in the remission stage, Guipi Decoction is administered to tonify Qi and nourish blood. During the treatment process, for patients with acute myocardial infarction complicated with acute upper gastrointestinal bleeding, it is crucial to flexibly apply the treatment principles of "Nil per os" in western medicine and "where there is stomach Qi, there is life; where there is no stomach Qi, there is death" in TCM. Early intervention with Huangtu Decoction can also prevent bleeding, with large doses being key to achieving hemostasis. It is important to address the pathogenesis of heat syndrome in addition to the core pathogenesis of Yang deficiency bleeding and to emphasize the follow-up treatment with Guipi Decoction for a successful outcome.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.

This study aims to identify the active components and the mechanism of Jingqi Yukui Capsules(JQYK) in the treatment of gastric ulcer based on network pharmacology, and verify some key targets and signaling pathways through animal experiment. To be specific, first, the active components and targets of JQYK were retrieved from a Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine(BATMAN-TCM) and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the targets of gastric ulcer from GeneCards and Online Mendelian Inheritance in Man(OMIM) with the search term "gastric ulcer". The common targets of the two were the potential targets of the prescription for the treatment of the di-sease. Then, protein-protein interaction(PPI) network of key targets were constructed based on STRING and Cytoscape 3.7.2, followed by Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment by matescape database and pathway visualization by Omicshare. For the animal experiment, the improved method of Okabe was used to induce gastric ulcer in rats, and the model rats were classified into the model group, JQYK high-dose(JQYK-H), medium-dose(JQYK-M), and low-dose(JQYK-L) groups, Anweiyang Capsules(WYA) group, and Rabeprazole Sodium Enteric Capsules(RBPZ) group. Normal rats were included in the blank group. Rats in the blank group and model group were given distilled water and those in the administration groups received corresponding drugs. Then gastric ulcer healing in rats was observed. The changes of the gastric histomorphology in rats were evaluated based on hematoxylin-eosin(HE) staining, and the content of inducible nitric oxide synthase(iNOS) in rat gastric tissue was detected with Coomassie brilliant blue method. The mRNA and protein levels of some proteins in rat gastric tissue were determined by real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot(WB) to further validate some key targets and signaling pathways. A total of 206 active components and 535 targets of JQYK, 1 305 targets of gastric ulcer, and 166 common targets of the disease and the drug were yielded. According to PPI analysis and KEGG pathway enrichment analysis, multiple key targets, such as interleukin-6(IL-6), tumor necrosis factor(TNF), mitogen-activated protein kinase 1(MAPK1), MAPK3, and MAPK14, as well as nuclear factor kappa-B(NF-κB) signaling pathway, IL-17 signaling pathway, and leukocyte transendothelial migration in the top 20 key signaling pathways were closely related to inflammation. The key protein p38 MAPK and NF-κB signaling pathway were selected for further verification by animal experiment. The gastric ulcer in the JQYK-H group recovered nearly to the level in the blank group, with significant decrease in the content of iNOS in rat gastric tissue and significant reduction in the mRNA and phosphorylation levels of p38 MAPK and the mRNA and protein levels of NF-κB p65 in rat gastric tissue. The results indicated that JQYK can inhibit the phosphorylation of the key protein p38 MAPK and the expression of NF-κB p65 in the NF-κB signaling pathway, thereby exerting the anti-inflammatory effect and effectively improving the quality of gastric ulcer healing in rats. Thus, the animal experiment result verifies some predictions of network pharmacology.
