ObjectiveTo investigate the effects of three traditional Chinese medicine formulas for nourishing kidney Yin on the occurrence of breast cancer, including Zuoguiwan(ZGW), Liuwei Dihuangwan(LWDHW) and Erzhiwan(EZW), and to explore their preventive mechanisms from the phagocytic function of macrophages. MethodsTen-month-old post-breeding female mice were randomly divided into the blank group, soy isoflavone group(0.13 g·kg-1·d-1, mixed with feed), ZGW group(2.34 g·kg-1·d-1), LWDHW group(0.56 g·kg-1·d-1), and EZW group(4.68 g·kg-1·d-1). The mice were palpated every 3 d until the age of 18 months, and those with detected lumps were confirmed for tumor development through hematoxylin-eosin(HE) staining, and the incidence of breast cancer in mice was calculated. A total of 40 SPF-grade female SD rats were randomly divided into the blank serum group(physiological saline), ZGW drug-containing serum group(16.20 g·kg-1·d-1of ZGW), LWDHW drug-containing serum group(3.89 g·kg-1·d-1 of LWDHW) and EZW drug-containing serum group(32.40 g·kg-1·d-1 of EZW), each group was orally administered 3 times a day for 5 consecutive days. On the 5th day, blood was collected from the abdominal aorta 1 h after the last gavage to prepare drug-containing serum. The effect of drug-containing serum with different concentrations on the viability of RAW264.7 cells was assessed by cell counting kit-8(CCK-8). Taking 20% of drug-containing serum concentration as the research object, its effect on the expression levels of major histocompatibility complex-Ⅱ(MHC-Ⅱ), CD80 and CD86 on the surface of RAW264.7 cells was detected by immunofluorescence(IF), the phagocytic function of RAW264.7 cells was examined by flow cytometry, and the levels of interleukin-6(IL-6) and nitric oxide(NO) in RAW264.7 cells in the conditioned medium(CM) co culture system of 4T1 cells were detected by enzyme-linked immunosorbent assay(ELISA) and Griess assay. ResultsAfter prophylactic administration, the tumor incidence rates in the soy isoflavone group(4%), ZGW group(4%), LWDHW group(4%), and EZW group(6%) were lower than that in the blank group(8%). Compared with the blank serum group, the drug-containing serum of the three nourishing kidney Yin formulas could enhance the expression levels of MHC-Ⅱ, CD80 and CD86 on the surface of RAW264.7 cells, enhance phagocytic ability towards tumor cells, and reduce the content of IL-6 and increase the level of NO(P<0.05, P<0.01). ConclusionThe three nourishing kidney Yin formulas can reduce the incidence of tumor in mice, the mechanism may be related to activating RAW264.7 cells, increasing their phagocytosis to breast cancer cells, and regulating the secretion of IL-6 and NO.

Premature ejaculation refers to a sexual dysfunction in which men experience a short intravaginal ejaculation latency and a lack of control over ejaculation during sexual activity. The onset of this condition is often accompanied by anxiety and depression, which can seriously affect the quality of the patient′s sexual life and the relationship between partners. Based on the "integration of body and spirit" theory in traditional Chinese medicine, our team believes that this condition is a comorbidity of physical and spiritual factors. We propose that the core pathogenesis of this disease lies in the "loss of form and essence, impairment of spirit, and depression of the mind, "while the primary treatment principle involves "nourishing form and regulating spirit." As a result, a new diagnosis and treatment approach of "four-dimensional integration" is summarized in this study. The disease is treated through the four dimensions of shape, body, spirit, and emotion. Traditional Chinese medicine is used to adjust the shape in cases where the physical form is damaged. For individuals with depression of heart and liver qi, the treatment focuses on soothing the heart and smoothing liver qi, and the modified Wangyou Powder and Xuanzhi Decoction is used. In cases where the heart and kidney function are compromised, the treatment involves nourishing both the heart and kidney while restoring interaction between the heart and the kidney, and modified Jihuo Yansi Elixir is used. To reduce the sensitivity of the glans penis, the patient′s body is washed with a traditional Chinese medicine formula, and a delicate fumigation formula is decocted for external washing. For those who are not in tune with their god, psychological counseling can be used to regulate their spirit and advocate "self-partner" and psychotherapy. If there are issues with intimacy, partners should focus on cooperating during foreplay, sexual intercourse, and post-coital interactions. Overall, the treatment aims to harmonize the body and spirit, addressing both physical and psychological factors through a comprehensive, multi-dimensional approach. This method provides new perspectives and ideas for the clinical diagnosis and treatment of this condition.

The Medical Cases of WU Jutong (《吴鞠通医案》) proposes the principle of "treating all Bi (痹) diseases through taiyin", which forms the basis for analyzing WU Jutong's understanding of the causes, mechanisms, and treatments of Bi (痹) diseases, providing a reference for clinical diagnosis and treatment. Through an interpretation of the phrase "treating all Bi (痹) diseases through taiyin", it is suggested that Bi (痹) diseases is primarily caused by dampness, necessitating a focus on spleen and lung in treatment. WU emphasized four main causes of Bi (痹) diseases (wind, cold, dampness, and heat), with dampness being the predominant factor. The disease location is initially in lung, for which external dampness invades lung first, and internal dampness obstructs the source of water metabolism, impeding lung qi and qi failing to disperse, then dampness further accumulates in the joints, leading to Bi (痹) diseases. WU Jutong proposed the modified Mufangji Decoction (木防己汤) as the foundational prescription for treating Bi (痹) diseases. By comparing the similarities and differences between the modified and original Mufangji Decoction, and analyzing the adjustments in herbal prescriptions, the clinical characteristic of "treating all Bi (痹) diseases through taiyin" is further substantiated.

Objective To track and evaluate the implementation and application of the occupational health standard Radiation shielding requirements for radiotherapy room—Part 4: Radiotherapy room of 252Cf neutron afterloading (GBZ/T 201.4-2015) by radiation health technical service agencies, medical institutions, health supervision agencies, and radiotherapy facility design units, and to provide a scientific basis for the further revision and implementation of this standard. Methods Following the Guideline for health standards tracking evaluation (WS/T 536-2017) and the project implementation plan, relevant practitioners were randomly selected for a questionnaire survey. The survey primarily focused on their awareness, standard training, application, and revision suggestions of GBZ/T 201.4-2015. The results were summarized and analyzed. Results A total of 168 evaluation questionnaires were collected from relevant practitioners in 28 provinces. Only 31.6% of the respondents reported being “well familiar” or “ familiar” with the standard, 27.4% of the respondents believed that the standard was widely used, and 45.2% of the respondents believed that the standard could meet the needs of their work. Only 14.9% of the respondents had received relevant training on the standard, more than half of the respondents had not applied the standard within the past 10 years, and 45.2% of the respondents believed that the standard "needs to be revised". Conclusion Due to the small number of californium-252 neutron afterloading radiotherapy devices in operation on the market, the overall awareness of the standard is low, suggesting that relevant authorities need to strengthen training and publicity of the standard, and that certain sections of the standard need to be revised or merged.

Breast milk is the optimal natural food for newborns. However, some newborns cannot receive maternal breast milk due to reasons such as mother-infant separation or insufficient lactation. The establishment of human milk banks (HMB) can effectively address these issues, thereby increasing the breastfeeding rate among hospitalized newborns and improving their quality of survival. However, HMB in China is still in the development and improvement stage. Its implementation involves a series of ethical issues, such as informed consent, privacy protection, economic incentives, quality and safety, and fair resource distribution, which hinder HMB’s widespread promotion. Therefore, discussing the ethical dilemmas faced by the widespread establishment of HMB in China’s hospitals and analyzing coping strategies are crucial for improving the breastfeeding rate of newborns. This paper deeply analyzed and sorted out the ethical issues and challenges currently faced by HMB in China, and proposed corresponding strategies, including “ensuring informed consent and voluntary participation of both donors and recipients,” “protecting the privacy of donors and recipients,” “establishing an ethics-based moral incentive and social support system,” “strictly controlling quality and safety issues”, and “developing fair and rational policies,” aiming to provide a reference solution for addressing ethical concerns in the establishment and operation of HMB.

Objective:To investigate the application effect of population/patient, intervention/exposure, comparison/control, and outcome (PICO) principles based on evidence-based medicine in case reports of residents in operative dentistry and endodontics.Methods:A total of 56 residents in Department of Conservative Dentistry and Endodontics in Hospital of Stomatology, Sun Yat-sen University, were selected and randomly divided into experimental group and control group, with 28 residents in each group. The residents in the experimental group were guided by the teachers to apply PICO principles in preparing case reports, and those in the control group were guided by the teachers to prepare traditional case reports. The two groups were compared in terms of the language expression of case reports, the completeness of case records, the rationality and advancement of the diagnosis and treatment regimen, and the logicality and scientificity of discussion, and a questionnaire survey was performed for both groups. SPSS 24.0 software was used to perform the descriptive statistical analysis, the t-test, and the chi-square test. Results:The experimental group had a significantly higher mean score of case report than the control group in department examination [(89.25±3.24) vs. (86.32±3.55), t=3.23, P=0.002], especially the score of the logicality and scientificity of discussion [(27.25±0.16) vs. (23.78±0.36), t=8.77, P<0.001]. The questionnaire survey showed that the experimental group had a significant increase in the frequency of participating in case reports ( P=0.035). Conclusions:The application of PICO principles can enhance the overall quality of case reports by residents and improve their enthusiasm in participating in case reports in department of operative dentistry and endodontics.

Cancer is a major global health issue. Effective therapeutic strategies can prolong patients’ survival and reduce the costs of treatment. Drug repurposing, which identifies new therapeutic uses for approved drugs, is a promising approach with the advantages of reducing research costs, shortening development time, and increasing efficiency and safety. Disulfiram (DSF), a Food and Drug Administration (FDA)-approved drug used to treat chronic alcoholism, has a great potential as an anticancer drug by targeting diverse human malignancies. Several studies show the antitumor effects of DSF, particularly the combination of DSF and copper (DSF/Cu), on a wide range of cancers such as glioblastoma (GBM), breast cancer, liver cancer, pancreatic cancer, and melanoma. In this review, we summarize the antitumor mechanisms of DSF/Cu, including induction of intracellular reactive oxygen species (ROS) and various cell death signaling pathways, and inhibition of proteasome activity, as well as inhibition of nuclear factor-kappa B (NF-κB) signaling. Furthermore, we highlight the ability of DSF/Cu to target cancer stem cells (CSCs), which provides a new approach to prevent tumor recurrence and metastasis. Strikingly, DSF/Cu inhibits several molecular targets associated with drug resistance, and therefore it is becoming a novel option to increase the sensitivity of chemo-resistant and radio-resistant patients. Studies of DSF/Cu may shed light on its improved application to clinical tumor treatment.

Vascular calcification is a highly regulated process of ectopic calcification in cardiovascular system while no effective intervention can be clinically performed up to date.As vascular calcification undergoes a common regulatory mechanism within bone formation,bone morphogenetic protein 7(BMP-7)main-tains contractile phenotype of vascular smooth muscle cells and further inhibits vascular calcification via promoting the process of osteoblast differentiation,reducing ectopic calcification pressure by increasing bone formation and reducing bone resorption.This work systematically reviews the role of BMP-7 in vascular calcifi-cation and the possible mechanism,and their current clinical application as well.The current proceedings may help develope early diagnostic strategy and therapeutic treatment with BMP-7 as a new molecular marker and potential drug target.The expec-tation could achieve early prevention and intervention of vascular calcification and improve poor prognosis on patients.

Aim To investigate the intracellular up-take and target protein binding characteristics of two Bruton's tyrosine kinase inhibitors(BTKi)with differ-ent selectivities to provide further insights into the mechanisms of drug off-target-related bleeding risk.Methods Ibrutinib(non-selective BTKi)and za-nubrutinib(selective BTKi)were used as study drugs.After incubation of MEC-1 cells and human platelets with drugs,the cellular thermal shift assay(CETSA)was combined with Western blot to obtain the melting curve and isothermal curve to analyze the binding char-acteristics of the two drugs with the target protein BTK.After incubation of MEC-1 cells and human platelets with drugs,the concentrations of the two drugs were detected by liquid chromatography-tandem mass spectrometry(LC-MS/MS)to analyze the intracellular uptake of the two drugs.Results CETSA analysis confirmed that zanubrutinib was more selective for the target protein BTK compared to ibrutinib.LC-MS/MS analysis showed that both drugs were uptaken intracel-lularly by MEC-1 cells and platelets in a concentration-dependent manner.Conclusions While BTKi targe-ting BTK to B lymphocytes exerts therapeutic effects,off-target effects on platelets due to differences in their intracellular uptake,and target-binding characteristics may be one of the reasons for the differences in bleed-ing risk across selective BTKi.
