The present study identified chemical constituents of Honghua Xiaoyao Tablet (HXT) and explored its biological connotation and characteristics on the premenstrual syndrome (PMS) treatment from the "disease-syndrome-symptom" association network. UHPLC-Q Exactive Orbitrap HRMS technology was applied to analyze the chemical constituents in HXT. According to the composition principles, the compatible herbs of HXT were divided into the Shugan Jieyu group, Huoxue Tiaojing group and Yiqi Jianpi group. The candidate targets of the corresponding prescriptions of HXT efficacy groups were collected from the Pharmmapper database and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0. The gene set related to the clinical symptoms included in Traditional Chinese and Western Medicine diagnosis and treatment standards were obtained from SoFDA, GeneCards, DisGeNET, MalaCards and literature published. The "HXT candidate targets-PMS (liver depression, Qi stagnation, and blood stasis syndrome) genes" network was constructed based on the gene interaction information, and further, the core network targets were screened out by topological characteristics of calculating network, and the functional exploration was carried out based on Kyoto Encyclopedia of Genes and Genomes (KEGG) for exploring the therapeutic advantages in PMS treatment of HXT efficacy groups, which were further verified experimentally in vitro. A total of 109 components from HXT were identified, including 20 components from Shugan Jieyu group enriched in the neurological system, estrogen regulation, and "immune-inflammation" related pathways, 77 components from Huoxue Tiaojing group enriched in the blood-circulation system, "immune-inflammation" and estrogen regulation related pathways and 30 components from Yiqi Jianpi group regulating immune inflammation, digestive system, and hormone levels. The biochemical indicator detection demonstrated that both the levels of 5-HT and DA in the hypothalamus tissues and the levels of E₂, NO, VEGF and RLN in the uterine tissues of PMS model rats were lower than those in controls, which the levels of OT, PROG, IL-6, IL-1β and TNF-α in the uterine tissues were increased in PMS group, which were all reversed by the administration of HXT, indicating that this prescription may regulate the synthesis and secretion of estrogen, intervene in neurotransmitter synthesis and signal transduction, reverse the imbalance of "immune-inflammation", and regulate digestive system function through various biological pathways, exerting the liver-smoothing, Qi-regulating, blood-activating and spleen-tonifying comprehensive effects, leading to alleviating the "neuroendocrine-endocrine-immune" system and blood-circulation disorders. The relevant results may provide a reference for clarifying the advantages and efficacy of HXT in treating PMS with liver stagnation, Qi stagnation, and blood stasis syndrome, and exploring its therapeutic advantages. The animal experiment of this study was approved by the Ethics Committee of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences (approval number: 2023B248).

Background: Cryptococcal meningitis is a severe infectious disease associated with high morbidity and mortality.Rapidity and accuracy of diagnosis contribute to better prognosis,but readily available tools,such as microscopy,culture,and antigens do not perform well all the time.Our study attempted to diagnose and genotype cryptococcus in the cerebrospinal fluid(CSF)samples from patients with cryptococcal meningitis using the approach of metataxonomics of Internal Transcribed Spacer(ITS)amplicons.Methods: The CSF samples were collected from 11 clinically suspected cryptococcal meningitis patients and four non-infectious controls.Samples were recruited from the First Affiliated Hospital of Fujian Medical University Hospital,Fuzhou Fourth Hospital and the 476th Hospital of Chinese People's Liberation Army from December 2017 to December 2018.ITS1 ribosomal deoxyribonucleic acid(rDNA)genes of 15 whole samples were amplified by universal forward primer ITS1(CTTGGTCATITA-GAGGAAGTAA)and reverse primer ITS2(GCTGCGTTCTTCATCGATGC),sequenced by Illumina MiSeq Benchtop Sequencer.The results were confirmed by sanger sequencing of ITS1 region and partial CAP59 gene of microbial isolates from 11 meningitic samples.Pair-wise comparison between infectious group and control group was conducted through permutational multivariate analysis(PERMANOV A)in R software.Results: The 30,000 to 340,000 high-quality clean reads were obtained from each of the positively stained or cultured CSF samples and 8 to 60 reads from each control.The samples from 11 infected patients yielded detectable cryptococcal-specific ITS1 DNA with top abundance(from 95.90％to 99.97％),followed by many other fungal groups(each ＜1.41％).ITS genotype was 4efined in 11 CSF samples,corresponding to ITS type 1,and confirmed by Sanger sequencing.A statistically significant difference(r2=0.65869,P = 0.0014)between infectious group and control group was observed.Conclusions: The metataxonomics of ITS amplicons facilitates the diagnosis and genotype of cryptococcus in CSF samples,which may provide a better diagnostic approach of cryptococcal infection.

Objective: This study aimed to determine the effect of radiotherapy (RT) on the risk of herpes zoster (HZ) in patients with gynecological cancers via a nationwide population-based study. Methods: Based on patient data obtained from the National Health Insurance Research Database, 1928 gynecological cancer patients were identified with 1:1 matching for RT and non-RT cohorts by age, index date, and cancer type. Another cohort consisting of 964 noncancer individuals matched was used as normal control. The incidence of HZ was compared between cancer patients with and without RT. Age, comorbidities, cancer-related surgery and chemotherapy (CT), and cancer type were adjusted as confounders. Results: The risk of HZ in cancer patients was higher than that of non-cancer individuals (14.23 versus 8.34 per 1,000 person-years [PY], the adjusted hazard ratio [aHR]=1.38, p=0.044). In the cancer population, the incidence of HZ for the RT and non-RT cohorts was 20.55 versus 10.23 per 1,000 PY, respectively (aHR=1.68, p=0.009). Age >50 years was an independent factor for developing HZ. The 5-year actuarial incidence for patients receiving neither RT nor CT, RT alone, CT alone, and combined modalities was 5.4%, 6.9%, 3.7%, and 9.9%, respectively (p<0.001). In the RT cohort, the risk rose rapidly in the first year, becoming steady thereafter. Conclusion This population-based study showed that gynecological cancer patients receiving RT combined with CT had the highest cumulative risk of HZ. Health care professionals should be aware of the potential toxicities.
