ObjectiveTo observe the effects of Hei Xiaoyaosan on the learning and memory abilities of Alzheimer's disease model mice （APP/PS1 mice）， and to explore its mechanism through the inflammatory cascade mediated by nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 （NLRP3）/cysteine aspartate-specific protease （Caspase-1）/gasdermin D （GSDMD） signaling pathway. MethodsSPF-grade 4-month-old APP/PS1 mice were randomly divided into the model group， MCC950 group， and Hei Xiaoyaosan high-， medium-， and low-dose groups. C57BL/6J mice were used as the blank group. After 7 days of adaptive feeding， mice in each group were intervened. The Hei Xiaoyaosan high-， medium-， and low-dose groups were given corresponding doses by gavage （25.79， 12.90， 6.45 g·kg^-1·d^-1）， the MCC950 group was intraperitoneally injected with 10 mg·kg^-1·2 d^-1， and the blank group received the same volume of physiological saline by gavage. After 90 days of intervention， the learning and memory abilities were assessed using the Y maze and Morris water maze tests. The structural changes of hippocampal neurons were observed by hematoxylin-eosin （HE） staining. The expression of amyloid precursor protein （APP） in the hippocampal CA3 region was detected by immunohistochemistry. Enzyme-linked immunosorbent assay （ELISA） was used to measure the levels of interleukin （IL）-10， IL-18， and IL-1β in the hippocampus. Western blot was applied to detect the protein expression of NLRP3， Caspase-1， GSDMD， and GSDMD-N in the hippocampus. Immunofluorescence was used to detect the co-localization of GSDMD-N and ionized calcium-binding adapter molecule-1 （Iba-1） in the hippocampus. Results① In the Y maze test， compared with the blank group， the spontaneous alternation rate of the model group was significantly reduced （P<0.01）. Compared with the model group， the spontaneous alternation rate in the Hei Xiaoyaosan high- and low-dose groups was significantly increased （P<0.01）. ② In the Morris water maze test， during the 1-4 days of the location navigation test， the escape latency time of mice decreased with the extension of training time. On day 4， compared with the blank group， the model group showed a significantly increased escape latency （P<0.05）. Compared with the model group， the MCC950 group and the Hei Xiaoyaosan low-dose group showed significantly reduced escape latency （P<0.05）. In the spatial exploration experiment， compared with the blank group， the number of platform crossings in the model group was significantly reduced （P<0.01）. Compared with the model group， the Hei Xiaoyaosan low-dose group showed significantly increased platform crossings （P<0.05）. ③ HE staining showed that， compared with the blank group， the hippocampal CA3 cells of the model group were damaged， arranged loosely and irregularly， swollen， with unclear boundaries， and the nuclei were pyknotic and deeply stained. MCC950 and all doses of Hei Xiaoyaosan improved the hippocampal CA3 cell damage in APP/PS1 mice to varying degrees. ④ Immunohistochemical results indicated that， compared with the blank group， the expression of APP in the hippocampal CA3 region was significantly increased in the model group （P<0.01）. MCC950 and all doses of Hei Xiaoyaosan could reduce the expression of APP in the hippocampal CA3 region of APP/PS1 mice （P<0.01）. ⑤ ELISA results showed that the levels of IL-18 and IL-1β in the hippocampus of mice in the model group were significantly increased， and IL-10 levels were significantly reduced （P<0.01）. Compared with the model group， the IL-18 levels in the MCC950 group and the Hei Xiaoyaosan medium- and low-dose groups were significantly reduced （P<0.01）. IL-1β levels in the hippocampus of the MCC950 group and Hei Xiaoyaosan high-， medium-， and low-dose groups were significantly decreased （P<0.01）. The IL-10 levels in the hippocampus of the MCC950 group and the Hei Xiaoyaosan medium- and low-dose groups were increased （P<0.05， P<0.01）. ⑥ Western blot results showed that compared with the blank group， the protein levels of NLRP3， Caspase-1， GSDMD， and GSDMD-N in the hippocampus of the model group were significantly elevated （P<0.01）. Compared with the model group， the content of NLRP3 and Caspase-1 in the hippocampus of the treated groups was decreased （P<0.05， P<0.01）. The content of GSDMD in the hippocampus of the Hei Xiaoyaosan high-， medium-， and low-dose groups was reduced （P<0.05， P<0.01）， and the content of GSDMD-N in the hippocampus of the Hei Xiaoyaosan medium- and low-dose groups was decreased （P<0.05， P<0.01）. ⑦ Immunofluorescence results showed that， compared with the blank group， the co-expression of GSDMD-N and Iba-1 in the hippocampus of the model group was significantly increased （P<0.01）. Compared with the model group， the co-expression of GSDMD-N and Iba-1 in the treated groups was significantly reduced （P<0.01）. ConclusionHei Xiaoyaosan may regulate the NLRP3/Caspase-1/GSDMD signaling pathway to affect the release of inflammatory factors， alleviate neuroinflammation，improve hippocampal histopathological changes，and improve learning and memory deficits，thus providing potential therapeutic benefits for Alzheimer's disease.

The exploration and pilot studies of applying blockchain to drug supply chain show great potential in promoting information sharing, collaboration competence among the actors, regulatory efficiency, and etc. In the future, with the help of blockchain, the optimization of the entire supply chain for orphan drugs is expected to be realized. However, there is no such exploration in China at present. This paper systematically sorts out the whole process of supply chain for orphan drugs and the existing problems of the chain. The article concludes that at present, blockchain is mainly used in the " circulation" and " use" of the drug supply chain. It helps to improve the traceability of drugs, to cope with the problem of counterfeit drugs, to enable actors of the drug supply chain to form a collaborative network in optimizing resource allocation, and to improve the operation and supervision efficiency of the supply chain. In the future, the application faces challenges such as high costs in system conversion, lack of personnel awareness, and incomplete supporting systems. Based on the three dimensions of technology, practice, and research, this paper also looks into the future and suggests for the future use of blockchain in the supply chain of orphan drugs by constructing a practice model, the so called DI-GIVE (Digital, Intelligence, Government′s supervision, Innovation, Views of variety, Evaluation-based) hoping to innovate the supply chain of orphan drugs and to ensure the drug use for the patients with rare diseases in China.

OBJECTIVE To summarize the implementation experiences of the China Hospital Association’s Clinical Pharmacist Instructor Training Program Reform， and to evaluate the effectiveness of the reform， thus continuously enhancing the quality and standards of clinical pharmacist instructor training. METHODS The study drew on project evaluation methodologies to summarize the main characteristics of the comprehensive system and new model for clinical pharmacist instructor training established through the reform by literature review. The “learning assessment” and “reaction assessment” were conducted by using Kirkpatrick’s four-level model of evaluation in order to evaluate the effectiveness of the clinical pharmacist instructor training reform through statistically processing and analyzing the performance data and teaching evaluation data of the instructor participants. Based on problem and trend analysis， the future development directions were anticipated for the reform of clinical pharmacist instructor training. RESULTS & CONCLUSIONS The latest round of clinical pharmacist instructor training reform initiated by the Chinese Hospital Association had initially established a four-pronged training system encompassing “recruitment， training， assessment， and management”. It had also forged a training 。 model “oriented towards enhancing clinical teaching competency， with practical learning and skill-based assessment conducted on clinical teaching sites as its core”. Following a period of over three years of gradual reform， the new training system and model became increasingly mature. In both 2023 and 2024， the participants achieved relatively high average total scores in their initial completion assessments [with scores of （84.05± 5.83） and （85.82±4.35） points， respectively]. They also reported a strong sense of gain from the training reform [with self- perceived gain scores of （4.80±0.44） and （4.85±0.39） points， respectively]. The operation and implementation effects of the reform were generally satisfactory. In the future， clinical pharmacist instructor training reforms should continue to address the issues remaining from the current phase， while aligning with global trends in pharmacy education and industry development. Additionally， sustained exploration and practice will be carried out around the core objective of “enhancing clinical teaching competence”.

The peripheral pulmonary lesions are located far from the central airway and close to the pleura, so it is a challenge for clinical diagnosis of their nature through biopsy. Therefore, the Ion robot-assisted bronchoscopy system which has started its commercialization in China is proposed to diagnose and treat peripheral pulmonary lesions. The Ion system can be used for navigation, registration, biopsy and treatment. In this paper, the structural principle of the Ion system is expounded, and its technical advantages such as shape perception, slender catheter and flexible operation are summarized. It represents the latest development direction of the diagnosis and treatment of peripheral pulmonary lesions. Then, the clinical application and development status of the Ion system are analyzed and discussed in detail. Finally, the development trend of the robot-assisted bronchoscopy system is prospected, which provides new ideas for realizing the "integrated and one-stop" diagnosis and treatment services for peripheral pulmonary lesions based on this system.

Acute respiratory distress syndrome (ARDS) is the leading cause of respiratory failure with high morbidity and mortality. Pulmonary surfactant (PS)-based complementary therapies have exhibited potential for ARDS healing and applied as an adjunctive therapy strategy. Coacervate (Coac) has the characteristics of softness, deformability and excellent molecular enrichment properties, and has attracted extensive attention in the biomedical field. Here PS and coacervate were combined for the potential ARDS treatment. The Coac, fabricated from polyallylamine hydrochloride (PAH) and adenosine triphosphate (ATP) by simple mixing, exhibited soft droplet property and high enrichment for dexamethasone sodium phosphate (DSP). To avoid the fusion effect of membraneless coacervate and endow it with biological functions of PS, liposomes with PS-biomimetic lipid components (PS-lipo) were further introduced to construct PS-biomimetic membranized coacervate (DSP@PS-Coac). The DSP@PS-Coac demonstrated high lung targeting effect and significant penetration efficiency after intravenous injection. Furthermore, PS-lipo replenished the endogenous PS pool and facilitated the distribution of DSP in inflammatory cells in the lung. In the ARDS mouse model, PS-Coac and DSP exerted synergetic anti-inflammatory functions, via reducing the recruitment of inflammatory neutrophils and modulating macrophages into anti-inflammatory phenotype. The overall results confirmed that DSP@PS-Coac may provide a promising delivery option for the treatment of ARDS.

Congenital orofacial cleft, the most common birth defect in the maxillofacial region, exhibits a wide range of prognosis depending on the severity of deformity and underlying etiology. Non-syndromic congenital orofacial clefts typically present with milder deformities and more favorable treatment outcomes, whereas syndromic congenital orofacial clefts often manifest with concomitant organ abnormalities, which pose greater challenges for treatment and result in poorer prognosis. This consensus provides an elaborate classification system for varying degrees of orofacial clefts along with corresponding diagnostic and therapeutic guidelines. Results serve as a crucial resource for families to navigate prenatal screening results or make informed decisions regarding treatment options while also contributing significantly to preventing serious birth defects within the development of population.

Objective:To study on anti-osteoporosis effect of different extracts of Polygoni Multiflori Radix Praeparata on zebrafish.Methods:Three kinds extracts of Polygoni Multiflori Radix Praeparata, anthraquinone and stilbene glycosides and the removal of anthraquinone and stilbene glycosides were prepared. Prednisolone was used to construct the osteoporosis model of young zebrafish. Normal control group, model group, disodium etidronate group and low-, medium- and high-dosage groups of different extracts of Polygoni Multiflori Radix Praeparata were set up. Alizarin red staining was used to investigate the mineralized skull area and bone density of juvenile zebrafish in each group. Alkaline phosphatase (AKP) and tartrate-resistant acid phosphatase (TRACP) kits were used to detect the activity of osteoblast and osteoclast enzymes in zebra larvae. The qRT PCR method was used to detect the mRNA expressions of osteoporosis related genes Runx2b, col1a2, sparc, and vdrb in each group of zebrafish.Results:Compared with model group, the skull mineralized area and bone mineral density in different extracts of Polygoni Multiflori Radix Praeparata significantly increased ( P<0.01). Polygoni Multiflori Radix Praeparata, anthraquinone and stilbene glycosides and the removal of anthraquinone and stilbene glycosides (medium- and high-dosage) could significantly increase the AKP activity of zebrafish ( P<0.01), and lower the TRAP activity of zebrafish ( P<0.01); the mRNA expression levels of Runx2b, col1a2, sparc and vdrb in juvenile zebrafish osteoporosis model were significantly up-regulated by different extracts of Polygoni Multiflori Radix Praeparata. ( P<0.01). Conclusion:Polygoni Multiflori Radix Praeparata, Anthraquinone and stilbene glycosides and the removal of anthraquinone and stilbene glycosides show better anti-osteoporosis effects. The comparison of the efficacy of three extracts from Polygonum multiflorum shows that in addition to anthraquinone and stilbene glycosides, other chemical components of Polygonum multiflorum have anti-osteoporosis effects.

Gout is a metabolic disease closely associated with hyperuricemia and urate deposition. Because of the complex pathogenesis， high morbidity， multiple complications， and increasingly young patients， gout has received worldwide attention. Currently， western medicine mainly treats gout by lowering the uric acid level and reducing inflammation， which， however， causes serious adverse reactions and has contraindications. Phellodendri Chinensis Cortex （PCC） is the dried bark of Phellodendron chinense， with the effects of clearing heat， drying dampness， purging fire， detoxifying， and treating sores. Studies have shown that PCC and its active components have anti-inflammatory， pain-relieving， uric acid-lowering， and anti-gout activities， with extensive sources and high safety. PCC and its active components could prevent and treat gout through multi-targets and multi-pathways， whereas the systematic review remains to be carried out. Therefore， this paper summarized the pharmacological activities and mechanisms of PCC and its active components in the treatment of gout. The available studies have shown that PCC and its active components exert the anti-gout effect by lowering the uric acid level， reducing inflammation， alleviating oxidative stress， and regulationg intestinal flora， and protecting the kidneys. Particularly， the active components represented by alkaloids contribute obviously to the therapeutic effect of of PCC. Herein， we analyzed the problems and future development of the research on PCC， aiming to provide theoretical support and a scientific basis for the research and development of new drugs against gout.

Objective:To study the changes of intestinal flora before and after dietary intervention in pregnant women with gestational diabetes mellitus (GDM) and explore its correlation with the results of oral glucose tolerance test (OGTT), using third generation high-throughput sequencing of full-length 16S rDNA.Methods:Thirty pregnant women who received regular antenatal care in the First Affiliated Hospital of Xinjiang Medical University between July 2022 and March 2023 were selected. Demographic data and laboratory examination results of these pregnant women were collected. The pregnant women with GDM (the GDM group) were given individualized dietary intervention, while the control group were given routine dietary guidance, for a total of 2 weeks. The stool was collected before and after the intervention in both groups, and a total of 60 stool samples were collected. Through the PacBio Sequencing platform, the third generation sequencing of full-length 16S rDNA was utilized to investigate the intestinal microbiome diversity. The composition, abundance and diversity of intestinal flora were compared between groups, both before and after the intervention.Results:There were 74 species showing significant differences in abundance between the two groups of pregnant women, 54 of which were enriched in the GDM group. The correlation analysis of blood glucose levels tested by OGTT as an environmental factor showed that Lachnospirales ( P=0.002) and unclassified Bacteria ( P=0.035) were positively correlated with OGTT-0h blood glucose ( P<0.05), while Christensenellales ( P=0.018)and Oscillospirales ( P=0.045) negatively. Lachnospirales ( P=0.027)and unclassified Bacteria ( P=0.028) were positively correlated with OGTT-1 h blood glucose ( P<0.05), while Oscillospirales ( P=0.025) negatively. There was a positive correlation between Lachnospirales ( P=0.027) and OGTT-2h blood glucose ( P<0.05). Conclusions:After the individualized diet intervention, the dominant bacteria of the intestinal flora changed and the fasting blood glucose of declined in pregnant women with GDM. It's a reasonable presumption that individualized diet intervention can contribute to the regulation of the disordered intestinal flora in pregnant women with GDM, which implies a role of dietary intervention in the treatment of GDM.
