ObjectiveTo investigate the chemical constituents of Chuanxiong Rhizoma-Paeoniae Radix Rubra(CRPRR) that cross the blood-brain barrier in rats with ischemic stroke, their brain-protective effects, and their impact on inflammatory factors including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-18 (IL-18) based on ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) and pharmacodynamic experiments. MethodsA focal cerebral ischemia-reperfusion injury model was established in rats via the middle cerebral artery occlusion/reperfusion (MCAO/R) method using intraluminal suture. Neurological function was evaluated using behavioral scoring. UPLC-Q-TOF-MS was employed to identify the chemical constituents of CRPRR that crossed the blood-brain barrier and entered the cerebrospinal fluid in MCAO/R model rats. Male Sprague-Dawley rats were randomly divided into six groups: sham operation group, model group, low-, medium-, and high-dose CRPRR groups (1.35, 2.7, 5.4 g·kg-1, respectively), and an edaravone group (5 mg·kg-1), with 12 rats in each group. The sham and model groups received normal saline, while the treatment groups received the respective doses of CRPRR once daily by gavage for three consecutive weeks. The brain-protective effects of CRPRR were assessed using the Longa five-point scoring method, open field test, Morris water maze, 2,3,5-triphenyltetrazolium chloride (TTC) staining, hematoxylin and eosin (HE) staining, and transmission electron microscopy. ResultsNine chemical constituents were identified in the cerebrospinal fluid containing CRPRR, namely paeoniflorin, senkyunolide F, senkyunolide G, paeonimetabolin Ⅰ, paeoniflorin derivative, senkyunolide H, benzoylpaeoniflorin, senkyunolide A, and ligustilide. Animal experiment results showed that compared with the sham operation group, the model group exhibited disordered neuronal arrangement, severe vacuolation, nuclear pyknosis, and evident mitochondrial swelling. Chromatin aggregation and peripheralization were also observed. Neurological scores and the number of crossings in the central region were significantly increased (P<0.01), while platform crossings were significantly decreased (P<0.01), and clear infarct areas were present (P<0.01). Serum levels and protein expression of TNF-α, IL-1β, and IL-18 were significantly elevated (P<0.01). Compared with the model group, all dose groups of CRPRR showed marked improvement in neuronal morphology which was close to the normal level, with mitochondrial swelling alleviated and chromatin distribution more uniform. The medium- and high-dose groups significantly reduced neurological scores (P<0.01), while the low-, medium-, and high-dose groups significantly reduced the number of central crossings (P<0.01) and infarct volume (P<0.01), and decreased TNF-α, IL-1β, and IL-18 levels (P<0.05, P<0.01) compared with the model group. Furthermore, the medium- and high-dose groups significantly reduced TNF-α protein expression (P<0.05,P<0.01), and the high-dose group significantly reduced IL-1β and IL-18 protein expression (P<0.01). ConclusionThis study confirmed that CRPRR improves neurological function and alleviates brain tissue damage in MCAO/R rats. Its mechanism may be associated with the downregulation of inflammatory factors TNF-α, IL-1β, and IL-18, as well as the presence of nine active chemical constituents in cerebrospinal fluid, namely paeoniflorin, senkyunolide F, senkyunolide G, paeonimetabolin Ⅰ, paeoniflorin derivative, senkyunolide H, benzoylpaeoniflorin, senkyunolide A, and ligustilide, which are closely related to their brain-protective effects.

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.

Synthetic biology is a crucial tool for the development of the bio-industry and bio-economy, representing a significant aspect of new quality productive forces. As a core course for graduate students in bioengineering, Synthetic Biology plays a vital role in ensuring the supply of essential talents for the development of the bio-industry in the new era. To better serve regional economic development and provide high-level talents for China's progress in the bio-industry, we analyzed typical issues encountered in the past teaching activities, set up a multi-disciplinary teaching team, optimized the course contents, adjusted the teaching mode, and mobilized students' learning interest. With the application of scientific research project as the starting point, we guided students to think and discuss deeply through the simulation of application writing and project defense, which improved students' critical thinking and innovative thinking. With industrialization as a focus, we explored a new training model combining production, education, and research through the joint practice base of the university and enterprises introduced typical cases of biomanufacturing to encourage students to engage in scientific research. The teaching reform significantly enhances the comprehensive abilities and national sentiments of graduate students. This paper hopes to serve as a reference for colleagues engaged in teaching in this field.

This paper summarized Professor YE Jianzhou's experience in treating atopic dermatitis (AD) in children with the method of regulating the heart and treating the spirit. According to the clinical manifestations of itching-sleep psychological disorders in children with AD, and the physiological characteristics of "heart qi is prone to hyperactivity" and "liver qi is prone to hyperactivity" in children, it is believed that heart and spirit disharmony is an important pathogenesis of AD in children.From the concept of holism in traditional Chinese medicine, the principle of regulating the heart and treating the spirit has been proposed for treatment of AD in children, which is based on the theory of "the five zang (脏) organs store the spirit". In the acute stage, it is recommended to clear the heart, drain fire and calm the spirit with self-made Qingxin Ningshen Decoction (清心宁神汤) in modifications. In the chronic stage, the method of nourishing the heart, unblocking the meridians and calming the spirit is recommended, by using self-made Yangxin Anshen Decoction (养心安神汤) with modifications. The method to tranquilize the heart, subdue yang and contain the spirit should be implemented throughout the entire treatment, and yang-subduing and spirit-containing medicinals such as Duanlonggu (Os Draconis Praeparatum), Duanmuli (Concha Ostreae Praeparatum) and Zhenzhumu (Concha Margaritiferae Usta) are usually used to treat the body and the spirit simultaneously. All these are offered to provide new ideas for the individualized treatment of children with AD.

OBJECTIVE To investigate the current situation of pharmaceutical clinic service in medical institutions in China and provide experience and suggestions for promoting the development of pharmaceutical clinics. METHODS Questionnaire survey was used to investigate the development of pharmaceutical clinics in medical institutions of 31 provinces (autonomous regions and municipalities directly under the central government) in March to April 2023, and the descriptive analysis was conducted. The regression analysis was carried out for the influential factors of pharmaceutical clinic service. RESULTS A total of 1 368 questionnaires were distributed in this survey and 1 304 valid questionnaires were collected with the effective response rate of 95.32%. A total of 463 medical institutions carried out pharmaceutical clinic service, the rate of which was 35.51% (463/1 304); the rates of pharmaceutical clinics in tertiary, secondary, primary and other medical institutions were 52.80%, 17.18% and 5.88%, respectively. The frequency of opening pharmaceutical clinics was 3.17 days per week on average, with an average of 5.99 visiting pharmacists in each medical institution. Among the visiting pharmacists, clinical pharmacists accounted for the vast majority (88.68%, 2 459/2 773). There were various categories of pharmaceutical clinics, including joint clinics and pharmacist-independent clinics; among pharmacist-independent clinics, pharmaceutical specialty/specialty disease clinics were the main ones, accounting for 89.72% of the total number of pharmaceutical clinics. The value of pharmacists in pharmaceutical clinics was manifested in various forms, among which the proportion of medical institutions charging pharmaceutical clinics was 10.80%. The main experiences in developing pharmaceutical clinics were to attach importance to discipline construction and personnel training. The main difficulties in developing pharmaceutical clinics were low compensation levels and a shortage of talent.The number of clinical pharmacists, the number of visiting pharmacists in pharmaceutical clinics and additional compensation were positively correlated with the amount of pharmaceutical clinic services(P<0.05). CONCLUSIONS In recent years, pharmaceutical clinics have made significant progress; in the future, it is still necessary to further strengthen discipline construction and talent cultivation, pay attention to the value embodiment of pharmacists, to promote the healthy development of pharmaceutical clinics.

OBJECTIVE To explore the independent risk factors of voriconazole (VCZ)-related liver injury in elderly patients with hypoproteinemia. METHODS Elderly patients with invasive fungal infection and hypoproteinemia who were hospitalized in the respiratory intensive care unit of our hospital and treated with VCZ from August 2020 to July 2023 were selected. They were divided into group A (liver injury group) and group B (non-liver injury group) based on whether the liver injury occurred after using VCZ. Pearson correlation analysis was used to analyze the correlation between minimum concentration (cmin) of VCZ and inflammatory factor[C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6)], as well as liver function [alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), gamma-glutamyl transpeptidase (GGT), total bilirubin (TBIL)]; univariate analysis was performed by using χ 2 test; Logistic regression analysis was used to analyze the independent risk factors affecting the occurrence of liver injury. RESULTS A total of 320 patients were included in the study, of whom 56 developed liver injury, with an incidence of 17.50%. The VCZ cmin in group A was significantly higher than group B (P= 0.021). CRP, PCT, IL-6, and TBIL were correlated with VCZ cmin (P<0.05). CRP, PCT, IL-6, and TBIL had a significant impact on VCZ cmin (P<0.05). VCZ cmin, PCT, and TBIL were independent risk factors for liver injury (P<0.05). The patients with VCZ cmin≥3.76 mg/L had a significantly increased risk of liver injury. CONCLUSIONS VCZ cmin, PCT, and TBIL are independent risk factors for the occurrence of liver injury in elderly patients with hypoproteinemia. For patients with high PCT and TBIL, VCZ cmin and liver function should be closely monitored during VCZ treatment to reduce the risk of liver injury.
