ObjectiveTo explore the pharmacological mechanism involved in the treatment of allergic cough (AC) by Xiaoer Huatan Zhike granules (XEHT) based on proteomics and network pharmacology. MethodsAfter sensitization by intraperitoneal injection of 1 mL suspension containing 2 mg ovalbumin (OVA) and 100 mg aluminum hydroxide, a guinea pig model of allergic cough was constructed by nebulization with 1% OVA. The modeled guinea pigs were randomized into the model, low-, medium- and high-dose (1, 5, 20 g·kg-1, respectively) XEHT, and sodium montelukast (1 mg·kg-1) groups (n=6), and another 6 guinea pigs were selected as the blank group. The guinea pigs in drug administration groups were administrated with the corresponding drugs by gavage, and those in the blank and model groups received the same volume of normal saline by gavage, 1 time·d-1. After 10 consecutive days of drug administration, the guinea pigs were stimulated by 1% OVA nebulization, and the coughs were observed. The pathological changes in the lung tissue were observed by hematoxylin-eosin staining. The enzyme-linked immunosorbent assay was performed to measure the levels of C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD), and malondialdehyde (MDA) in the bronchoalveolar lavage fluid (BALF) and immunoglobulin G (IgG) and immunoglobulin A (IgA) in the serum. Immunohistochemistry (IHC) was employed to observe the expression of IL-6 and TNF-α in the lung tissue. Transmission electron microscopy was employed observe the alveolar type Ⅱ epithelial cell ultrastructure. Real-time PCR was employed to determine the mRNA levels of IL-6, interleukin-1β (IL-1β), and TNF-α in the lung tissue. Label-free proteomics was used to detect the differential proteins among groups. Network pharmacology was used to predict the targets of XEHT in treating AC. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was performed to search for the same pathways from the results of proteomics and network pharmacology. ResultsCompared with the blank group, the model group showed increased coughs (P<0.01), elevated levels of CRP, TNF-α, IL-6, and MDA and lowered level of SOD in the BALF (P<0.05, P<0.01), elevated levels of IgA and IgG in the serum (P<0.05, P<0.01), congestion of the lung tissue and infiltration of inflammatory cells, increased expression of IL-6 and TNF-α (P<0.01), large areas of low electron density edema in type Ⅱ epithelial cells, obvious swelling and vacuolization of the organelles, karyopyknosis or sparse and dissolved chromatin, and up-regulated mRNA levels of IL-6, IL-1β, and TNF-α (P<0.01). Compared with the model group, the drug administration groups showed reduced coughs (P<0.01), lowered levels of CRP, TNF-α, IL-6, and MDA and elevated level of SOD in the BALF (P<0.05, P<0.01), alleviated lung tissue congestion, inflammatory cell infiltration, and type Ⅱ epithelial cell injury, and decreased expression of IL-6 and TNF-α (P<0.01). In addition, the medium-dose XEHT group and the montelukast sodium group showcased lowered serum levels of IgA and IgG (P<0.05, P<0.01). The medium- and high-dose XEHT groups and the montelukast sodium showed down-regulated mRNA levels of IL-6, IL-1β, and TNF-α and the low-dose XEHT group showed down-regulated mRNA levels of IL-6 and TNF-α (P<0.05, P<0.01). Phospholipase D, mammalian target of rapamycin (mTOR), and epidermal growth factor receptor family of receptor tyrosine kinase (ErbB) signaling pathways were the common pathways predicted by both proteomics and network pharmacology. ConclusionProteomics combined with network pharmacology reveal that XEHT can ameliorate AC by regulating the phospholipase D, mTOR, and ErbB signaling pathways.

Objective:
To analyze the infection characteristics of newly reported HIV/AIDS cases in Hangzhou City, so as to provide the reference for effective AIDS intervention.
Methods:
Newly reported HIV/AIDS cases in Hangzhou City in 2022 were recruited. Demographic information, HIV testing status, infection routes and sexual behaviors were collected using questionnaire surveys. Blood samples were collected before antiviral treatment, and HIV-1 pol gene sequences were detected to construct molecular transmission networks. The characteristics of HIV/AIDS cases, including infection routes, time, and location were analyzed. Factors affecting infection time and location among HIV/AIDS cases were analyzed using a multivariable logistic regression model.
Results:
A total of 1 007 HIV/AIDS cases were reported in Hangzhou City in 2022, with 907 cases (90.07%) completing questionnaire surveys. Among them, 833 were males (91.84%), and 532 had out-of-province household registrations (58.65%). Ninety-one molecular transmission networks were established, and 276 cases were involved, with homosexual contact as the main infection route (199 cases, 72.10%). There were 311 recently infected cases (35.34%) and 569 previously infected cases (64.66%) among 880 cases whose infection time could be determined. There were 531 locally infected. cases (70.24%) and 225 imported cases (29.76%) among 756 cases whose infection location could be determined. Multivariable logistic regression analysis showed that the HIV/AIDS cases who were identified through voluntary counseling and testing (OR=1.826, 95%CI: 1.055-3.175) and sought sexual partners through homosexual dating apps (OR=2.461, 95%CI: 1.193-5.234) were more likely to be recently infected; the cases who lived in Hangzhou City for more than one year (>1 to 5 years, OR=2.853, 95%CI: 1.552-5.358; >5 years, OR=3.534, 95%CI: 1.382-9.804), sought sexual partners through entertainment venues (OR=3.449, 95%CI: 1.390-8.935), online/social apps (OR=2.416, 95%CI: 1.084-5.488) and homosexual dating apps (OR=3.734, 95%CI: 1.677-8.493) were more likely to be locally infected; student cases were more likely to be infected outside Hangzhou City (OR=0.115, 95%CI: 0.019-0.525).
Conclusions
The newly reported HIV/AIDS cases in Hangzhou City in 2022 were primarily infected through homosexual contact, previously and locally. Seeking sexual partners through homosexual dating apps is an important influencing factor for recent and local infections, highlighting the need for strengthening traceback investigations of related cases.

Breast cancer is one of the most common cancers in the world, and its incidence rate is also rising in China and tends to happen in younger age groups. The classical Wnt/β-catenin signaling pathway is an important target in the treatment of breast cancer, playing a key role in the whole process of breast cancer development by regulating the expression of related signal proteins and genes. Traditional Chinese medicine has a profound history and practical experience in the treatment of malignant tumors, and the development of modern technology further highlights the therapeutic advantages of traditional Chinese medicine, which has multiple targets and components. Research shows that Chinese medicine can effectively slow down the proliferation of breast cancer cells by regulating the Wnt/β-catenin signaling pathway, and has a significant inhibitory effect on the development of breast cancer. Based on this, this paper summarized domestic and foreign relevant studies on the regulation of the Wnt/β-catenin signaling pathway with traditional Chinese medicine in the treatment of breast cancer, analyzed the mechanism of traditional Chinese medicine treating breast cancer by intervening in this signaling pathway, and summarized 44 different types of traditional Chinese medicine monomers, including terpenes (triptolide, andrographolide, etc.), flavonoids (scutellarin, sinensetin, etc.), polysaccharides (Angelica sinensis polysaccharides, etc.), phenols (curcumin, polydatin, etc.), and alkaloids (lycorine, etc.). In addition, there are 3 traditional Chinese medicines (Ganoderma lucidum, Radix actinidia chinensis, and Antrodia camphorata), 1 group of medicine pairs (Trionycis Carapax-Zedoary Turmeric), and 8 traditional Chinese medicine formulas (Compound Tubeimu, Huangqi Jiedu Tang, Xihuang Wan, Liuwei Dihuang Wan, Jiazhu Tang, Aiduqing Fang, Sini San, and compound Kushen injection). By regulating the Wnt/β-catenin signaling pathway and its key molecules, these single herbs, monomers, and compound herbs can reverse the epithelial mesenchymal transformation process, reduce the activity of stem cells, and inhibit the growth and metastasis of cancer cells. Besides, it can also enhance the sensitivity of drugs and radiotherapy and combat breast cancer, providing a new perspective for drug development and treatment strategies for breast cancer.

OBJECTIVE To provide reference for optimizing or formulating unified evaluation methods for evidence and recommendation in expert consensus on off-label use of drugs. METHODS Retrieved from CNKI, Wanfang data, VIP, CBM, PubMed and Web of Science, Chinese expert consensuses on off-label use of drugs involving evaluation methods for evidence and recommendations were collected from the inception to August 1, 2024. After screening the literature and extracting relevant data, descriptive statistical analysis was conducted. RESULTS & CONCLUSIONS Among the 32 articles included, 14 articles (43.8%) used Micromedex’s Thomson grading system, only 7 articles (21.9%) considered economic factors when forming recommendations, 10 articles (31.3%) reported the conflicts of interest; only 2 articles (6.3%) involved experts in the field of evidence-based medicine methodology. There were differences in the sources of evidence, factors considered in forming recommendations, and the grading standards for evidence and recommendations among different expert consensus evidence evaluation methods. There were also differences in evidence levels and recommendation strength of the same drug off-label use in different expert consensus. It is recommended that in future consensus-building processes, greater attention should be paid to potential conflicts of interest among participants, collaboration with methodological experts should be enhanced, and efforts should be expedited to establish unified standards for evaluating evidence and recommendation methodologies.

Prostate cancer is a malignant tumor that primarily arises from the epithelial tissue of the prostate in men. With the aggravation of population aging in China, the incidence rate of this disease has been continuously rising. Although the exact cause of prostate cancer remains unclear, it has been proven to be closely related to various factors, including individual genetic susceptibility, genetic mutations, dietary habits, and lifestyle. Research has shown that abnormal activation of the Wnt/β-catenin signaling pathway also plays an important role in the occurrence and development of prostate cancer. Multiple experimental results have revealed that traditional Chinese medicine (TCM), with its multi-target and multi-stage mechanisms of action, exerts significant regulatory effects on key biological processes such as proliferation, migration, invasion, angiogenesis, and epithelial-mesenchymal transition (EMT) of prostate cancer cells. TCM has shown excellent potential in preventing prostate cancer progression and improving patient prognosis and has become a research focus in prostate cancer treatment in recent years. Based on this, this study reviewed the research on the regulation of the Wnt/β-catenin signaling pathway by TCM in the treatment of prostate cancer at home and abroad. It analyzed the mechanisms by which TCM intervention exerts anti-prostate cancer effects via this signaling pathway, identifying 29 different types of active ingredients in TCM, including alkaloids (e.g., capsaicin, berberine), flavonoids (e.g., icariin and hyperoside), polyphenols (e.g., gastrodin and honokiol), terpenes (e.g., oridonin), quinones (e.g., aloe-emodin), coumarins (e.g., agrimonolide), and saponins (e.g., saikosaponin-d). Additionally, one TCM medicinal substance (arsenic), one drug pair (Danggui - Qieyi combination), and two TCM formulae (Yishen Tonglong Tang and Guben Qingyuan Formula) were included. The study aims to deepen the understanding of the pathological mechanism of prostate cancer and to explore possible therapeutic targets, thereby providing new perspectives and approaches for clinical research and new drug development, and ultimately promoting the advancement and innovation of prostate cancer treatment strategies.

Objective: To elucidate the expression level and transcript structure of the CD36 gene in megakaryocytes cultured in vitro. Methods: Using umbilical cord blood CD34
hematopoietic stem cells as the starting point, megakaryocytic lineage cells were directionally cultured in vitro using different combinations of cytokines. Total cell RNA was extracted from cultures at 0 d, 7 d, and 12 d, and megakaryocyte RNA was extracted from CD41a-sorted cells after 14 d and 18 d of culture. RNA-NGS sequencing technology was used to analyze the RNA gene expression profiles across the five culture periods and further investigate CD36 gene expression. Results: The number of megakaryocytes generated in the TPO (100 ng/mL) group [(2.2±0.02)×10
/mL] was significantly higher than that in the other five groups. A total of 22 066 expressed genes were detected in the RNA of the five culture periods, and gene expression levels at each time point were correlated with the culture timeline. CD36 gene expression increased with culture time, with FPKM values for CD36 expression in the megakaryocytic lineage at 14 d and 18 d being 18.35 and 101.85, respectively, which were much lower than those for ITGA2B and ITGB3 genes but slightly higher than that for CD109 gene in the megakaryocytic lineage. The longest transcript of CD36 in the 18 d megakaryocytic lineage was 3.8 kb, encompassing all sequence of exons E3 to E14 and a partial sequence of E15. Conclusion: This is the first report on the expression level and transcript structure of the CD36 gene in megakaryocytes cultured in vitro, providing fundamental data for research on the expression and regulation of the CD36 gene in the megakaryocytic lineage.
