Elemene, derived from Curcuma wenyujin, one of the "8 famous genuine medicinal materials of Zhejiang province," exhibits remarkable antitumor activity. It has gained wide recognition in clinical practice for effectiveness on tumors. Dr. XIE Tian, introduced the innovative concept of "molecular compatibility theory" by combining Chinese medicine principles, specifically the "monarch, minister, assistant, and envoy" theory, with modern biomedical technology. This groundbreaking approach, along with a systematic analysis of Chinese medicine and modern biomedical knowledge, led to the development of elemene nanoliposome formulations. These novel formulations offer numerous advantages, including low toxicity, well-defined composition, synergistic effects on multiple targets, and excellent biocompatibility. Following the principles of the "molecular compatibility theory", further exploration of cancer treatment strategies and methods based on elemene was undertaken. This comprehensive review consolidates the current understanding of elemene's potential antitumor mechanisms, recent clinical investigations, advancements in drug delivery systems, and structural modifications. The ultimate goal of this review is to establish a solid theoretical foundation for researchers, empowering them to develop more effective antitumor drugs based on the principles of "molecular compatibility theory".

Objective:To understand the epidemiological characteristics of human respiratory syncytial virus (HRSV) among acute respiratory infection (ARI) cases in 16 provinces of China from 2009 to 2023.Methods:The data of this study were collected from the ARI surveillance data from 16 provinces in China from 2009 to 2023, with a total of 28 278 ARI cases included in the study. The clinical specimens from ARI cases were screened for HRSV nucleic acid from 2009 to 2023, and differences in virus detection rates among cases of different age groups, regions, and months were analyzed.Results:A total of 28 278 ARI cases were enrolled from January 2009 to September 2023. The age of the cases ranged from<1 month to 112 years, and the age M ( Q1, Q3) was 3 years (1 year, 9 years). Among them, 3 062 cases were positive for HRSV nucleic acid, with a total detection rate of 10.83%. From 2009 to 2019, the detection rate of HRSV was 9.33%, and the virus was mainly prevalent in winter and spring. During the Corona Virus Disease 2019 (COVID-19) pandemic, the detection rate of HRSV fluctuated between 6.32% and 18.67%. There was no traditional winter epidemic peak of HRSV from the end of 2022 to the beginning of 2023, and an anti-seasonal epidemic of HRSV occurred from April to May 2023. About 87.95% (2 693/3 062) of positive cases were children under 5 years old, and the difference in the detection rate of HRSV among different age groups was statistically significant ( P<0.001), showing a decreasing trend of HRSV detection rate with the increase of age ( P<0.001). Among them, the HRSV detection rate (25.69%) was highest in children under 6 months. Compared with 2009-2019, the ranking of HRSV detection rates in different age groups changed from high to low between 2020 and 2023, with the age M (Q1, Q3) of HRSV positive cases increasing from 1 year (6 months, 3 years) to 2 years (11 months, 3 years). Conclusion:Through 15 years of continuous HRSV surveillance analysis, children under 5 years old, especially infants under 6 months old, are the main high-risk population for HRSV infection. During the COVID-19 pandemic, the prevalence and patterns of HRSV in China have changed.

This study explored the protective effect of astragaloside Ⅳ(AS-Ⅳ) on oxygen-glucose deprivation(OGD)-induced autophagic injury in PC12 cells and its underlying mechanism. An OGD-induced autophagic injury model in vitro was established in PC12 cells. The cells were divided into a normal group, an OGD group, low-, medium-, and high-dose AS-Ⅳ groups, and a positive drug dexmedetomidine(DEX) group. Cell viability was measured using the MTT assay. Transmission electron microscopy was used to observe autophagosomes and autolysosomes, and the MDC staining method was used to assess the fluorescence intensity of autophagosomes. Western blot was conducted to determine the relative expression levels of functional proteins LC3-Ⅱ/LC3-Ⅰ, Beclin1, p-Akt/Akt, p-mTOR/mTOR, and HIF-1α. Compared with the normal group, the OGD group exhibited a significant decrease in cell viability(P<0.01), an increase in autophagosomes(P<0.01), enhanced fluorescence intensity of autophagosomes(P<0.01), up-regulated Beclin1, LC3-Ⅱ/LC3-Ⅰ, and HIF-1α(P<0.05 or P<0.01), and down-regulated p-Akt/Akt and p-mTOR/mTOR(P<0.05 or P<0.01). Compared with the OGD group, the low-and medium-dose AS-Ⅳ groups and the DEX group showed a significant increase in cell viability(P<0.01), decreased autophagosomes(P<0.01), weakened fluorescence intensity of autophagosomes(P<0.01), down-regulated Beclin1, LC3-Ⅱ/LC3-Ⅰ, and HIF-1α(P<0.05 or P<0.01), and up-regulated p-Akt/Akt and p-mTOR/mTOR(P<0.01). AS-Ⅳ at low and medium doses exerted a protective effect against OGD-induced autophagic injury in PC12 cells by activating the Akt/mTOR pathway, subsequently influencing HIF-1α. The high-dose AS-Ⅳ group did not show a statistically significant difference compared with the OGD group. This study provides a certain target reference for the prevention and treatment of OGD-induced cellular autophagic injury by AS-Ⅳ and accumulates laboratory data for the secondary development of Astragali Radix and AS-Ⅳ.

The purpose of this study was to explore the clinical efficacy and safety of Gynostemma pentaphyllum (G. pentaphyllum) in the treatment of hyperlipidemia, and to provide systematic evaluation basis for clinical application. CNKI, Wanfang Data, VIP, Web of science, PubMed, Embase and Cochrane Library were searched for randomized controlled trials (RCTs) about G. pentaphyllum in the treatment of hyperlipidemia. Review Manager 5.4 were used for statistical analysis. Through reading topics, abstracts, and full texts, 27 papers with 2311 cases involved that met the inclusion and exclusion criteria were finally included for the analysis. In terms of curative effect, the effect of G. pentaphyllum alone in increasing high density lipoprotein (HDL) index was better than that of conventional treatment, and the effect of reducing total cholesterol (TC), triglyceride (TG) and low density lipoprotein (LDL) was similar to that of conventional treatment. There was a synergistic effect between G. pentaphyllum and conventional drugs, and the combination of G. pentaphyllum and conventional drugs was superior to conventional treatment in reducing TG and increasing HDL. G. pentaphyllum can also decrease the levels of serum glutamic pyruvic transaminase and glutamic oxaloacetic transaminase in the treatment of hyperlipidemia, indicating a certain protective function of the liver. In terms of safety, there were fewer cases of adverse reactions in the G. pentaphyllum treatment group, and the adverse reaction events reported in the literature was mild. According to the results of meta-analysis, G. pentaphyllum was effective in the treatment of hyperlipidemia, and it has the potential to be combined with traditional drugs, has a certain liver protection function, and was superior to traditional drugs in the treatment of hyperlipidemia.

Cancer, also known as malignant tumor, is the second largest disease after heart disease, which is characterized by genomic instability and mutagenicity. Ataxia telangiectasia and RAD3-related kinase (ATR) are members of phosphatidylinositol 3-kinase (PIKK) family, belonging to serine/threonine kinase, one of the key kinases in DNA damage response (DDR) and DNA repair pathway. This paper reviews the latest progress in the ATR inhibitor field including mechanism of action (MOA), therapeutic applications, and the combination therapy from the perspective of medicinal chemistry. It also discusses the possible challenges and future directions of developing ATR inhibitor antitumor drugs, which could provide the scientists in this field the convenience for access the information and application guidance for clinical studies.

Objective: To investigate whether the contralateral normal external auditory canal (EAC) skin graft can maintain the ear canal health after EAC reconstruction in unilateral congenital aural atresia (CAA) cases. Methods: A Zelen design randomized controlled study was used to collect unilateral CAA patients for EAC reconstruction prospectively (clinical trial registration number: ChiCTR2000032103). The patients were randomly divided into the control group and the trial group. The trial group used the contralateral normal EAC skin graft group (transplant part of the contralateral normal EAC skin to repair the atresia side for unilateral CAA patients), the control group all used scalp blade thick skin. We observed the EAC health and hearing results of the two groups after EAC reconstruction. Results: A total of 13 cases were enrolled from July 2020 to August 2021. There were eight patients in the trial group, including six males and two females, with an average age of 22.3 years (14-36 years). There were two patients with CAA on the left and six patients on the right. The average follow-up time was 8.8 months (4-14 months). There were five patients in the control group, all cases were male with an average age of 16.2 years (12-20 years). There were four patients with CAA on the left and one patient on the right. The average follow-up time was 7.0 months (2-14 months). In the trial group, eight cases of reconstructed EAC epithelium were healthy, one patient had cicatricial stenosis of EAC opening and lateralization of the tympanic membrane. The other patient had cicatricial stenosis of reconstructed EAC, this case also had scar hyperplasia of the contralateral EAC opening but recovered after soft packing and triamcinolone acetonide injection treatment. The healthy side EAC of the rest trial group had no scarring stenosis or local bone hyperplasia during long-term follow-up. In the control group, one patient was lost to follow-up and the other four patients had dry ears of reconstructed EAC, but easily to form crusts and needed to be cleaned repeatedly, one patient had lateralization of the tympanic membrane, the EAC epithelium was not healthy for long-term follow-up. The incidence of complications related to EAC reconstruction was lower than previous studies (χ²=5.55, P=0.018), and the average postoperative Air-Bone Gap increased (18.8±10.0)dB. Conclusion: By optimizing the EAC reconstruction technology, the health of the reconstructed EAC is improved compared with the previous study. After active intervention and treatment, there should be no scarring stenosis or local bone hyperplasia on the contralateral side EAC.
