As a distinctive resource of Chinese civilization， traditional Chinese medicine （TCM） technology transfer faces significant opportunities under the background of digital and intelligent transformation， while also being constrained by unique challenges such as the complexity of its theoretical system， lengthy industrial chains， and multidimensional policy restrictions， resulting in a "high-value-high-threshold" paradox. At present， TCM technology transfer is deeply trapped in a "threefold reluctance" dilemma， i.e.， unwillingness to transfer， inability to transfer， and lack of capacity to transfer. Specifically， the disconnection between scientific research evaluation systems and market demand leads to low conversion rates of research achievements， unclear ownership and compliance risks suppress innovation incentives， and the absence of professional services intensifies supply-demand mismatches. This article systematically analyzes the specific characteristics of TCM technology transfer and proposes a breakthrough pathway centered on full-chain digital and intelligent transformation. By integrating technologies such as intelligent sorting systems， blockchain-based traceability， and AI diagnostic models， the TCM ecosystem spanning "cultivation-production-service" can be reconstructed. In terms of standardization， promoting the progression from "experience-based data conversion" to "data standardization" and further to "intelligent standardization" is advocated to resolve quality control challenges. For example， a "three-no-one-full" certification system can strengthen quality trust. Policy coordination should focus on optimizing mechanisms for the transformation of scientific and technological achievements， while exploring intellectual property securitization and risk-sharing models to stimulate research momentum. In terms of internationalization， reliance on the Belt and Road Initiative platform to promote the export of geo-authentic medicinal material brands and standards is recommended to build a dual-driven model of "technology plus culture". Looking ahead， through the construction of national-level databases， the cultivation of interdisciplinary talent， and the mutual recognition of international standards， a new paradigm of "scientific intelligent manufacturing" can be formed， providing systematic solutions for the modernization of TCM and global health governance.

ObjectiveTo explore the effect of different drying conditions on the appearance and intrinsic quality indicators of Pinelliae Rhizoma for screening suitable drying conditions， so as to provide reference for its standardized production and quality evaluation. MethodsDifferent dried samples of Pinelliae Rhizoma were prepared by lime-assisted sweating method and intermittent drying method. Visual analysis was employed to measure the color brightness values（L^*） of the surface， cross-section and powder of the samples， texture analyzer was used to determine the hardness of the samples under different drying conditions. The total starch content was calculated by measuring the contents of amylose and amylopectin in the samples with ultraviolet-visible spectroscopy. High performance liquid chromatography（HPLC） was used to determine the contents of seven nucleoside components（uracil， hypoxanthine， uridine， inosine， guanosine， β-thymidine and adenosine） in the samples. Pearson correlation analysis was conducted to explore the correlation between the external characteristics and intrinsic indicators of the different dried samples. Principal component analysis（PCA） was used to comprehensively rank the data of various indicators， and partial least squares-discriminant analysis（PLS-DA） was used to screen differential components with variable importance in the projection（VIP） value>1. Furthermore， the difference between the optimal drying condition for Pinelliae Rhizoma and the traditional sun-drying method was explored by independent samples t-test. ResultsWith the increase of temperature， the color of the intermittently dried samples gradually deepened， while their hardness gradually decreased. Concurrently， the contents of extract， total starch， uridine and adenosine exhibited an upward trend， whereas the contents of uracil， hypoxanthine and inosine displayed a downward trajectory. Compared with the intermittent drying group， the content of extract in the samples subjected to lime-assisted sweating increased. With the increase of lime dose， the hardness and the total content of nucleoside components in the samples showed a downward trend， while the total starch content showed an upward trend. Correlation analysis showed that the comprehensive score of L^* was negatively correlated with the contents of uracil， hypoxanthine and inosine， and positively correlated with the contents of uridine， guanosine and adenosine. Hardness was negatively correlated with adenosine content， and positively correlated with the contents of inosine， uracil and hypoxanthine. Through comprehensive consideration and comprehensive score of principal components， the method of 5% lime-mixed sweating for 6 days emerged as the top-ranking approach. Except for the extract， the results of independent samples t-test showed that there was no significant difference between the 5% lime-mixed sweating for 6 days and the traditional sun-drying in terms of other content indicators. ConclusionThe whiteness and firmness of Pinelliae Rhizoma exhibit significant correlations with its chemical composition， while uridine， uracil， guanosine， adenosine and inosine are the key constituents responsible for the quality difference of Pinelliae Rhizoma under different drying conditions. The lime-assisted sweating method optimized in this study can be proposed as a viable alternative to the traditional sun-drying method. This method not only ensures the quality of the medicinal material but also effectively reduces the drying time and prevents mold contamination， which provides a valuable reference for the standardization of drying conditions and the establishment of quality evaluation criteria for Pinelliae Rhizoma.

Objective To evaluate the current situation of disease control in middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD) and analyze the relationship with disease cognition. Methods Among the 360 middle-aged and elderly COPD patients diagnosed and treated in our hospital from January 2022 to June 2024 were retrospectively selected as research subjects, and the COPD Assessment Test Questionnaire (CAT), COPD Patient Knowledge Questionnaire (BCKQ) and the hampion Health Belief Model Scale were used to evaluate disease control, disease cognition and health beliefs in COPD patients. The Pearson chi-square test was used to analyze the relationship between disease control level and disease cognition and health beliefs in older patients with COPD. Results A total of 360 middle-aged and elderly COPD patients, 112 were in the complete control group, 189 were in the partial control group, and 59 were in the uncontrolled group, the disease control rate was 83.61%. The differences in disease cognitive scores, severity cognition, susceptibility cognition, disorder cognition, benefit cognition, health motivation, self-efficacy score and total health belief scores in middle-aged and elderly COPD patients with different disease control conditions are statistically significant. The scores of the complete control group were higher than those of partial control group and uncontrolled group, and the scores of partial control group were higher than those of the uncontrolled group (P <0.05). The disease control level of middle-aged and elderly patients with COPD is positively correlated with disease cognitive level and health belief in all dimensions. The higher the disease control level, the higher the disease cognitive level and health belief in the patient . Conclusions Middle-aged and elderly COPD patients still have insufficient awareness of the disease, and the level of disease control needs to be improved. There is a significant correlation between disease cognition, health beliefs and the level of disease control, and the improved cognitive level may help to improve the disease management and control effect. For middle-aged and elderly COPD patients, the community can provide health education courses, personalized health guidance and self-management training to enhance their awareness of diseases, so as to improve the long-term management of COPD and the quality of life of patients.

Objective　To investigate the effects of capsaicin on gut microbiota and antimicrobial peptide expression of Anopheles stephensi, providing experimental references for the application of capsaicin in mosquito-borne disease prevention and control. Methods Anopheles stephensi were continuously fed with sugary water containing capsaicin or DMSO for the capsaicin-treated group and the control, respectively. The DNA of the female mosquito's midguts and gut bacteria was extracted. Bacterial 16S rDNA high-throughput sequencing and real-time fluorescence quantitative PCR were used to analyze and compare the bacteria diversity, gut flora composition, relative abundance, and total bacterial load in female mosquitoes’ midgut between the control and capsaicin treatment groups. Total RNA was extracted from the midguts of the two groups of Anopheles mosquitoes, and the transcriptional levels of important antimicrobial peptides were detected and compared by reverse transcription and real-time fluorescence quantitative PCR. Results A total of 10 phyla, 11 classes, 28 orders, 43 families, and 62 genera were identified in the two groups. The capsaicin-treated group had fewer taxa, with significantly reduced bacterial diversity, and different community composition and relative abundance of the flora compared to the control group. At the phylum level, Bacteroidota, Proteobacteria, and Firmicutes predominated in both two groups. At the order level, Flavobacteriales, Acetobacterales, Pseudomonadales, and Lactobacillales were the dominant bacteria, with reduced relative abundance of Pseudomonadales and Acetobacterales and increased relative abundance of Flavobacteriales and Lactobacillales in the capsaicin-treated group. At the genus level, Elizabethkingia was predominantly abundant in both samples, with higher relative abundance of Elizabethkingia, Leuconostoc, and Gluconobacter in the capsaicin-treated group, while Asaia and Acinetobacter had significantly lower relative abundance compared to the control group. In addition to these changes, the total bacterial load was increased and the transcriptional levels of attacin C, cecropin A, and defensin were significantly decreased by capsaicin treatment. Conclusions Capsaicin treatment significantly affects the composition of the gut flora in Anopheles stephensi and increases the total bacterial load while inhibiting the expression of antimicrobial peptides. Based on the analysis, it indicates that capsaicin might affect the fecundity and vector competence of Anopheles by changing the energy metabolism and immune-related bacteria.

OBJECTIVE: To observe the effect of acupuncture at "four pharyngeal points" on simple vocal tics with liver hyperactivity disturbed wind in children. METHODS: Sixty children with simple vocal tics of liver hyperactivity disturbed wind were randomly divided into an observation group (30 cases, 1 case dropped out) and a control group (30 cases). The control group was given Changma Xifeng tablets orally, 3 times a day, while the observation group was treated with acupuncture at "four pharyngeal points" on the basis of the treatment in the control group, 15-20 min a time, once daily for 7 days, with a 3-day break. Both groups were treated for 3 months. The TCM syndrome score and Yale global tic severity scale (YGTSS) score of the two groups were observed before treatment and after 1, 2, 3 months of treatment, the disappearance time of simple vocal tics was recorded, and the therapeutic efficacy was evaluated after treatment. RESULTS: After 1, 2, 3 months of treatment, the TCM syndrome scores and YGTSS scores of the two groups were decreased compared with those before treatment (P<0.01, P<0.05), and the scores of the observation group were lower than those in the control group (P<0.05, P<0.01). The disappearance time of simple vocal tics in the observation group was earlier than that in the control group (P<0.05). The effective rate of the observation group was 93.1% (27/29), which was higher than 73.3% (22/30) in the control group (P<0.05). CONCLUSION Acupuncture at "four pharyngeal points" could improve symptoms in children with simple vocal tics of liver hyperactivity disturbed wind, and shorten the disappearance time of simple vocal tics.

BACKGROUND: Poly adenosine-diphosphate-ribose polymerase (PARP) inhibitors (PARPi) have been approved to act as first-line maintenance (FL-M) therapy and as platinum-sensitive recurrent maintenance (PSR-M) therapy for ovarian cancer in China for >5 years. Herein, we have analyzed the clinical-application characteristics of olaparib and niraparib in ovarian cancer-maintenance therapy in a real-world setting to strengthen our understanding and promote their rational usage. METHODS: A retrospective chart review identified patients with newly diagnosed or platinum-sensitive recurrent ovarian cancer, who received olaparib or niraparib as maintenance therapy at Sichuan Cancer Hospital between August 1, 2018, and December 31, 2021. Patient medical records were reviewed. We grouped and analyzed patients based on the type of PARPi they used (the olaparib group and the niraparib group) and the line of PARPi maintenance therapy (the FL-M setting and the PSR-M setting). The primary endpoint was the 24-month progression-free survival (PFS) rate. RESULTS: In total, 131 patients (olaparib: n = 67, 51.1%; niraparib: n = 64, 48.9%) were enrolled. Breast cancer susceptibility genes ( BRCA ) mutations ( BRCA m) were significantly less common in the niraparib group than in the olaparib group [9.4% (6/64) vs . 62.7% (42/67), P <0.001], especially in the FL-M setting [10.4% (5/48) vs . 91.4% (32/35), P <0.001]. The 24-month progression-free survival (PFS) rates in the FL-M and PSR-M settings were 60.4% and 45.7%, respectively. In patients with BRCA m, the 24-month PFS rates in the FL-M and PSR-M settings were 62.2% and 72.7%, respectively. CONCLUSIONS Olaparib and niraparib were effective in patients with ovarian cancer without any new safety signals except for skin pigmentation. In patients with BRCA m, the 24-month PFS of the PARPi used in the PSR-M setting was even higher than that used in the FL-M setting.

This study identified 8 members including NjBIN2 of the GSK3 family in Nardostachys jatamansi by bioinformatics analysis. Moreover, the phylogenetic tree revealed that the GKS3 family members of N. jatamansi had a close relationship with those of Arabidopsis. RT-qPCR results showed that NjBIN2 presented a tissue-specific expression pattern with the highest expression in roots, suggesting that NjBIN2 played a role in root growth and development. In addition, the application of epibrassinolide or the brassinosteroid(BR) synthesis inhibitor(brassinazole) altered the expression pattern of NjBIN2 and influenced the photomorphogenesis(cotyledon opening) and root development of N. jatamansi, which provided direct evidence about the functions of NjBIN2. In conclusion, this study highlights the roles of BIN2 in regulating the growth and development of N. jatamansi by analyzing the expression pattern and biological function of NjBIN2. It not only enriches the understanding about the regulatory mechanism of the growth and development of N. jatamansi but also provides a theoretical basis and potential gene targets for molecular breeding of N. jatamansi with improved quality in the future.

Researchers commonly use cyclization recombination enzyme/locus of X-over P1 (Cre/loxP) technology-based conditional gene knockouts of model mice to investigate the functional roles of genes of interest in Sertoli and Leydig cells within the testis. However, the shortcomings of these genetic tools include high costs, lengthy experimental periods, and limited accessibility for researchers. Therefore, exploring alternative gene silencing techniques is of great practical value. In this study, we employed adeno-associated virus (AAV) as a vector for gene silencing in Sertoli and Leydig cells. Our findings demonstrated that AAV serotypes 1, 8, and 9 exhibited high infection efficiency in both types of testis cells. Importantly, we discovered that all three AAV serotypes exhibited exquisite specificity in targeting Sertoli cells via tubular injection while demonstrating remarkable selectivity in targeting Leydig cells via interstitial injection. We achieved cell-specific knockouts of the steroidogenic acute regulatory ( Star ) and luteinizing hormone/human chorionic gonadotropin receptor (Lhcgr) genes in Leydig cells, but not in Sertoli cells, using AAV9-single guide RNA (sgRNA)-mediated gene editing in Rosa26-LSL-Cas9 mice. Knockdown of androgen receptor ( Ar ) gene expression in Sertoli cells of wild-type mice was achieved via tubular injection of AAV9-short hairpin RNA (shRNA)-mediated targeting. Our findings offer technical approaches for investigating gene function in Sertoli and Leydig cells through AAV9-mediated gene silencing.
