Guishenwan (GSW), originating from Jingyue Quanshu (Zhang Jingyue's Complete Works), is a classic traditional Chinese medicine (TCM) formula with a history of over 400 years. Designed for kidney essence deficiency syndrome, it is clinically applied to treat diseases associated with essence-blood deficiency, such as ovarian insufficiency diseases in women, oligospermia-induced infertility in men, and lumbar disc herniation. Numerous studies have confirmed its significant efficacy and advantages in managing ovarian insufficiency diseases, including diminished ovarian reserve (DOR), premature ovarian insufficiency (POI), and premature ovarian failure (POF). According to recent literature, the therapeutic mechanisms of GSW in treating ovarian insufficiency diseases involve regulating the hypothalamic-pituitary-ovarian axis (HPOA) function, ameliorating reproductive endocrine disorders, improving ovarian function, modulating relevant signaling pathways, and exerting immunoregulatory and anti-inflammatory effects. A review of GSW in clinical treatment revealed that clinical applications of GSW, particularly in combination with Western medicine, not only alleviate symptoms but also compensate for the limitations of hormone replacement therapy, thereby reducing recurrence, minimizing adverse reactions, and enhancing safety. This review aims to provide a scientific basis for the rational clinical use of GSW in ovarian insufficiency diseases, offer innovative TCM strategies for developing novel ovarian-protective drugs, promote the integration of TCM and Western medicine in reproductive medicine, and ultimately contribute a Chinese approach to global management of ovarian insufficiency diseases.

To systematically analyzed the reporting status of core elements in publicly available clinical practice guideline(hereafter referred to as "guideline") protocols published domestically and internationally over the past decade, identified existing problems, and provided evidence to inform the standardized writing and publication of future guideline protocols. A systematic search was conducted in Chinese and English databases for clinical practice guideline protocols published during the past ten years. The basic characteristics and reporting of core elements—including registration information, conflict of interest management, evidence grading, development process and timeline planning, as well as dissemination and implementation—were extracted and analyzed. Chi-square tests were performed to explore associations between protocol characteristics and the reporting of core elements. A total of 94 guideline protocols were included, of which 67 were in Chinese(71.28%) and 27 were in English(28.72%). Overall, 82.98% of the guideline protocols were registered, 92.55% reported management of conflicts of interest, 97.87% reported evidence searching, 88.30% reported evidence grading, and 89.36% described dissemination and implementation strategies. However, only 55.32% reported the guideline development process, and merely 23.40% reported timeline planning. Further analysis indicated that the reporting of registration, evidence searching, development process, and timeline planning was associated with year of publication. Differences were observed between domestic and international guidelines in reporting registration, conflict of interest management, development process, time planning, and dissemination and implementation. Guidelines intended for development exhibited higher reporting rates for registration, development process, and dissemination and implementation compared to those planned for updating or adaptation. Although current guideline protocols demonstrate relatively adequate reporting of methodological elements, deficiencies remain in development process and timeline planning. Future efforts should focus on promoting the publication and standardized reporting of guideline protocols, enhancing the international recognition of registration platforms, and strengthening the development process and timeline planning to advance the scientific rigor and transparency of guideline development.

Dry eye (DE) is a prevalent multifactorial disease of the ocular surface, clinically characterized by tear film homeostasis imbalance accompanied by related ocular surface symptoms. Specifically, the tear film is a thin liquid layer of tears covering the cornea and conjunctiva through blinking, while tear film homeostasis serves as the foundation for maintaining normal ocular surface structure and function. Insufficient tear secretion and excessive tear film evaporation lead to tear hyperosmolarity and the production of inflammatory mediators, disrupting tear film homeostasis and subsequently forming DE. Additionally, cascade reactions are triggered, resulting in a "vicious cycle of DE" that exacerbates the disease severity and prolongs its duration. Therefore, for DE treatment, it is crucial to restore tear film homeostasis and terminate this vicious cycle. Traditional Chinese medicine (TCM), which differentiates and treats DE based on systemic conditions, often achieves favorable therapeutic outcomes, offering additional treatment options for DE. Studies have demonstrated that TCM can alleviate DE by regulating tear film homeostasis and terminating the vicious cycle. This review systematically summarizes recent basic experimental research in China and abroad on TCM in alleviating DE by regulating tear film homeostasis, aiming to provide a theoretical basis for clinical treatment and an insight for research design.

ObjectiveTo elucidate the underlying mechanism through which Zhuluan decoction suppresses excessive autophagy in human ovarian granulosa cells (KGN) and ameliorates premature ovarian insufficiency (POI) via the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. MethodsThe optimal concentration of cyclophosphamide for inducing a POI model in KGN cells was identified via the cell counting kit-8 (CCK-8) assay. Subsequently, the impacts of varying concentrations of Zhuluan decoction-containing serum on the viability of the KGN cell model were assessed. After the optimal drug concentration was determined, KGN cells were categorized into the following groups: blank control (20% blank serum), model (20% blank serum + 5 μmol·L-1 cyclophosphamide), Zhuluan decoction-containing serum (20% Zhuluan decoction-containing serum + 5 μmol·L-1 cyclophosphamide), autophagy inhibitor (20% blank serum + 5 μmol·L-1 cyclophosphamide + 20 μmol·L-1 chloroquine phosphate), autophagy inhibitor + Zhuluan decoction-containing serum (20% Zhuluan decoction-containing serum + 5 μmol·L-1 cyclophosphamide + 20 μmol·L-1 chloroquine phosphate), and estradiol valerate (20% estradiol valerate-containing serum + 5 μmol·L-1 cyclophosphamide). Following 48 hours of incubation, flow cytometry was utilized to measure the apoptosis rate of KGN cells in each group. Western blotting was employed to quantify the protein levels of PI3K, phosphorylated (p)-Akt, Akt, p-mTOR, and mTOR, along with the expression levels of autophagy-related proteins such as Beclin1, autophagy-related 5 homolog (ATG5), and microtubule-associated protein 1 light chain 3 (LC3), in each group. Additionally, monodansylcadaverine (MDC) staining was performed to evaluate the extent of autophagy in each group. ResultsIncubation of KGN cells with 5 μmol·L-1 cyclophosphamide for 48 h successfully established a POI model, marked by a significant inhibition of KGN cell proliferation. Notably, the inhibitory effect of cyclophosphamide on KGN cell proliferation exhibited a positive correlation with its concentration. Zhuluan decoction-containing serum at 20% and 30% promoted cell proliferation and mitigated the inhibitory effect of cyclophosphamide on KGN cell proliferation, with comparable therapeutic efficacy observed at both concentrations. Compared with the blank control group, the model group displayed an elevated apoptosis rate (P<0.01), reduced protein levels of PI3K, p-Akt, and p-mTOR (P<0.01), increased protein levels of Beclin1, LC3, and ATG5 (P<0.01), no significant alterations in the protein levels of Akt and mTOR, and an enhanced MDC autophagy fluorescence intensity (P<0.01). In comparison to that the model group, the apoptosis rates in the blank control group, model group, Zhuluan decoction-containing serum group, autophagy inhibitor group, autophagy inhibitor + Zhuluan decoction-containing serum group, and estradiol valerate group all reduced (P<0.05, P<0.01), with the most pronounced reduction observed in the autophagy inhibitor + Zhuluan decoction-containing serum group. The protein levels of PI3K, p-Akt, and p-mTOR were higher in other groups than in the model group (P<0.05, P<0.01), being the highest in the autophagy inhibitor + Zhuluan decoctio-containing serum group (P<0.01). The protein levels of Beclin1 and ATG5 were lower in other groups than in the model group (P<0.05, P<0.01). The expression level of LC3 declined in the Zhuluan decoction-containing serum group and the estradiol valerate group (P<0.05, P<0.01), while it decreased without statistical significance in the autophagy inhibitor group and the autophagy inhibitor + Zhuluan decoction-containing serum group. ConclusionZhuluan decoction may activate the PI3K/Akt/mTOR pathway to inhibit excessive autophagy and counteract the detrimental effects of cyclophosphamide on the KGN cell model, thus managing POI.

Objective To explore an artificial intelligence (AI)-based method for automated hand hygiene monitoring and to compare the effectiveness of three algorithms (UniFormerV2, TDN, C3D) in recognizing hand hygiene steps in surgical settings, thereby aiding hospital infection control. Methods From April to October 2024, we non-invasively collected 641 video recordings of healthcare staff performing hand hygiene at four-bay scrub sinks in two tertiary hospitals using overhead HD cameras. The dataset was annotated by five trained experts for model training and validation. Results Following training on 385 samples, internal validation (n=119) showed the C3D model achieved 81% accuracy, 87% recall, and an 83% F1-score. The TDN model achieved 93%, 91%, and 92% for the same metrics. The UniFormerV2 model outperformed both, with an accuracy, recall, and F1-score of 93%—an improvement of over 10 percentage points compared to traditional CNNs (TDN, C3D). It also achieved an 84% accuracy in external validation, demonstrating strong generalization. Conclusion The UniFormerV2 model is more accurate than CNN-based models for hand hygiene step recognition and shows robust performance in external validation. It presents a viable tool for healthcare facilities to enhance hand hygiene management, ultimately improving medical quality and patient safety.

ObjectiveMicrotube associated protein-2 (MAP-2), alpha-tubulin (α-tubulin), and synaptophysin (SYP) are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein (α-Syn) and its oligomers, MAP-2, α-tubulin, and SYP of patients with liver and kidney deficiency of Parkinson's disease (PD), analyzed their correlation, and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group (30 cases) and a control group (30 cases). Both groups were treated on the basis of PD medicine, and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score, TCM syndrome score, and expression of serum α-Syn and its oligomers, MAP-2, α-tubulin, and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment, the TCM syndrome score, UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ score of the treatment group were significantly decreased (P<0.05, P<0.01). The UPDRS score, UPDRS-Ⅱ score, and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment (P<0.05). After treatment, the total effective rate of the control group was 63.3% (19/30), and that of the treatment group was 86.7% (26/30). The clinical effect of the observation group was better than the control group (Z=-2.03, P<0.05). The total effective rate of the observation group was better than that of the control group, and the difference was statistically significant (χ2=5.136, P<0.05). After treatment, the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased (P<0.05, P<0.01). The levels of serum α-Syn and its oligomers, as well as α-tubulin in the treatment group, were significantly decreased compared with those in the control group after treatment (P<0.05, P<0.01). Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD (P<0.05, P<0.01) but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin (P<0.05, P<0.01) but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 (P<0.05). ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

ObjectiveA qualitative analysis method was established for the composition of Astragali Radix(AR) before and after rice stir-frying. On the basis of systematic characterization of the chemical compositions in AR and stir-fried AR with rice(ARR), the structures of their major compounds were deduced and identified, and the differential compositions between them were analyzed. MethodsUltra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) was used to detect the samples of AR and ARR in positive and negative ion modes, respectively. The compounds were analyzed and identified through self-constructed databases, literature, and reference standards, etc. And the data were analyzed by chemometrics, in order to screen for the differential components between AR and ARR. ResultsA total of 123 compounds were identified in AR and ARR, including 41 flavonoids, 19 terpenoids, 26 organic acids, 8 amino acids, 5 nucleotides, 5 carbohydrates and 19 other compounds. Among them, there were 95 common components in both, 18 unique components in AR, and 10 unique components in ARR. Principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) results both showed that there were significant differences in the chemical constituents of AR before and after rice stir-frying, and a total of 26 constituents with differences in the content were screened out, including L-canavanine, L-pyroglutamic acid, L-phenylalanine, cis-caffeic acid, and malonylastragaloside Ⅰ. Among them, 19 constituents of ARR were down-regulated and 7 constituents were up-regulated by comparing with AR. ConclusionThis study clarifies that the chemical composition of AR and ARR is mainly composed of flavonoids, terpenoids, and organic acids, and analyzes the components with significant differences in content between the two in combination with chemometrics, and the differential components are dominated by amino acids, organic acids and terpenoids, which can provide reference for the subsequent quality control and material basis research.

Objective To study the seasonal distribution characteristics of polycyclic aromatic hydrocarbons (PAHs) in PM2.5 in Lianyungang City, and analyze the sources of PAHs pollution, and to evaluate the health risks of PAHs in different seasons. Methods PM2.5 samples were collected regularly from January 2019 to December 2023, and 16 types of PAHs were determined by HPLC. Kruskal-Wallis H test was used to compare the concentrations of PM2.5 and PAHs in different years and seasons. The source of PAHs was analyzed by characteristic ratio and principal component analysis (PCA). Health risks were assessed using the BaP equivalent method and the incremental lifetime cancer risk (ILCR) model. Results The annual exceedance rates of PM2.5 and BaP in Lianyungang showed a decreasing trend from 2019 to 2023. PM2.5, total PAHs and PAHs monomers (except Ace, Flu and Acy) all showed significant seasonal differences, with the highest concentration in winter (P<0.001). The average proportion of 4-ring PAHs was the highest and the average proportion of 2-ring PAHs was the lowest. The proportion of 5-6 ring PAHs was relatively high in winter and spring. PM2.5and PAHs were negatively correlated with temperature, relative humidity and precipitation, and were positively correlated with atmospheric pressure. PM2.5 was negatively correlated with wind speed, while some PAHs monomers were positively correlated with wind speed. The characteristic ratio and PCA results showed that the main sources of PAHs in Lianyungang City were mixed sources of road dust and vehicle emissions, oil pollution sources and biomass combustion sources. The results of ILCR showed that the highest risk was found in adults, with males slightly higher than females. In Lianyungang, the maximum value of ILCR in winter was more than 10-6 in people over 9 years old. Conclusion The main sources of PAHs in PM2.5 in Lianyungang City are mixed sources of road dust and vehicle emissions, oil pollution sources, and biomass combustion sources. Under the current exposure level of PAHs in PM2.5, residents have a certain potential carcinogenic risk.
