Osteoarthritis (OA) and stroke are common clinical diseases that reduce patients' quality of life and place a burden on families and society. Ruyi Zhenbaowan, a classic prescription in Tibetan medicine, have the functions of clearing heat, awakening the brain and opening orifices, relaxing tendons and promoting meridian circulation, and eliminating yellow water. Clinically, they are used to treat osteoarthritis, post-stroke sequelae, neuropathic pain, and other related conditions. Modern pharmacological studies have demonstrated their anti-inflammatory, analgesic, and nerve-repairing effects. However, current research remains insufficient regarding the appropriate indications, timing, and efficacy of this medicine in treating relevant diseases. To enhance clinicians' understanding of this medicine and promote its standardized and rational clinical use, a panel of national experts, including clinical specialists, Tibetan medicine practitioners, pharmacologists, and methodologists, formulated this consensus based on clinical experience and evidence-based practice. The Cochrane systematic review framework, the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system, and the nominal group method were employed to generate seven graded recommendations and 19 consensus-based suggestions. These recommendations clearly define the key points in the clinical application of Ruyi Zhenbaowan, including therapeutic indications, dosage and administration, treatment duration, and medication safety. The consensus specifically addresses the clinical efficacy, appropriate timing of administration, dosage strategies, treatment cycles, and combination medication strategies for treating osteoarthritis and stroke and provides an overview of safety considerations. The aim is to provide standardized guidance for hospitals and healthcare institutions nationwide to ensure the rational application of Ruyi Zhenbaowan in the treatment of osteoarthritis and stroke, reduce medication-related risks, and further leverage its clinical advantages. This consensus has been approved and issued by the China Association of Chinese Medicine, with the standard number GS/CACM 369-2024.

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 investigate the effect of tritiated water on the immune system of zebrafish and its potential molecular mechanism. Methods Zebrafish embryos (2.5 to 3 hours post-fertilization [hpf]) were exposed to 3.7 × 104 Bq/mL tritiated water (tritiated water group), and those exposed to E3 culture medium were used as the control group. The mortality rate, hatching rate, deformity rate, heart rate, body length, yolk sac area, neutrophil count in the tail, immune-related gene expression, and immune-related protein expression of zebrafish in the two groups were determined. Then transcriptome technology was used to further analyze the possible mechanism of tritiated water affecting the immune system of zebrafish. Results Compared with the control group, zebrafish at 72 hpf in the tritiated water group had no significant changes in the mortality rate, hatching rate, deformity rate, body length, and yolk sac area((t = 0.9045, 0.5000, 1.0000, 0.7238, 0.0337, P = 0.4169, 0.6433, 0.3739, 0.4785, 0.9735), but had significantly increased heart rate(t = 4.575,P = 0.002). At 4 days post-fertilization (dpf), the neutrophil count in the tail of zebrafish in the tritiated water group was significantly increased(t = 2.563,P = 0.0196), the mRNA expression of TNF-α was significantly decreased(t = 2.891, P = 0.045), the protein expression of nuclear factor-kappa B (NF-κB) was significantly increased(t = 3.848, P = 0.018), and the protein expression of NLRP3 was significantly decreased(t = 14.98, P = 0.001). At 7 dpf, the neutrophil count in the tail and the protein expression levels of NF-κB, NLRP3, and interleukin-1β were significantly decreased(t = 3.772, 7.048, 15.620, 4.423, P = 0.014, 0.002, 0.0001, 0.012). Transcriptome sequencing revealed that differentially expressed genes were mainly enriched in the “neutrophil activation” and “platelet activation pathways” at 4 dpf and in the “neutrophil apoptosis”, “ferroptosis”, and “necroptosis” pathways at 7 dpf. Conclusion Tritiated water exposure induces a temporally dynamic immune response in zebrafish, potentially affecting immune homeostasis by regulating neutrophil activation and apoptosis, as well as the expression of NF-κB and NLRP3.

Thermal analysis technology has emerged as a pivotal tool for the identification and quality control of traditional Chinese medicine (TCM) owing to its advantages of high sensitivity and capability for simultaneous multi-parameter detection. The application progress on thermogravimetric analysis (TGA), differential thermal analysis (DTA), and differential scanning calorimetry (DSC) in four key areas: authenticity identification of herbal medicines, optimization of processing techniques, evaluation of extract thermal stability, and construction of quality evaluation systems were summarized. Thermal analysis technology enables rapid authentication of medicinal materials by establishing a thermal fingerprint. When integrated with hyphenated techniques (e.g., FTIR and GC-MS), it facilitates in-depth analysis of compositional differences in complex matrices. In Future, the development of thermal analysis databases and multi-technology integration will be expected to further promote the standardization of TCM quality control.

Objective:
To explore whether infected granulation tissue in tooth extraction sockets and maxillary sinus pus share a common microbial profile at the subspecies-strain level in patients with odontogenic maxillary sinusitis (OMS), providing evidence for infection origin tracing and precise antimicrobial therapy in OMS.
Methods:
This study was reviewed and approved by the institutional ethics committee. Nine consecutive OMS patients who underwent synchronous endoscopic sinus surgery and tooth extraction from October 2020 to August 2022 were prospectively enrolled. Under general anesthesia, paired specimens were collected from infected extraction-socket granulation tissue and maxillary sinus pus. Bacterial DNA was extracted, and the full-length 16S rRNA gene was sequenced on the Illumina MiSeq platform. Amplicon sequence variants (ASVs) were generated using the DADA2 algorithm and taxonomically annotated to the subspecies level against the Human Oral Microbiome Database. The detection rate of shared ASVs between the two sites and their relative abundance in sinus pus were compared. Functional profiles were predicted using Phylogenetic Investigation of Communities by Reconstruction of Unobserved States 2 (PICRUSt2).
Results:
Shared ASVs were identified in seven of the nine patients. Fusobacterium, Parvimonas, Porphyromonas, and Prevotella were the most prevalent genera. Porphyromonas gingivalis and Fusobacterium nucleatum were co-detected in multiple patients, with relative abundances exceeding 5% in sinus pus of several cases. Identical ASVs of F. nucleatum or Porphyromonas spp. were detected in six patients; the ASVs corresponding to F. nucleatum subsp. nucleatum and Porphyromonas endodontalis were significantly more abundant in sinus pus than in extraction-socket granulation tissue. PICRUSt2 functional profiling revealed that the proportion of socket-derived microbes in sinus pus was strongly correlated with 10 pathways, including ferroptosis, adipocytokine signaling, and apoptosis, et al. Except for biotin metabolism, the remaining pathways showed weak correlation with the proportion of extraction socket-derived ASVs in the extraction-socket granulation tissue and maxillary sinus pus. Removing F. nucleatum ASVs markedly attenuated these associations
Conclusion
At the subspecies-strain level, this study confirmed the presence of a shared microbial profile between infected extraction-socket granulation tissue and maxillary sinus pus in patients with odontogenic maxillary sinusitis. The co-detected subspecies-strains with high relative abundance in maxillary sinus pus included Fusobacterium nucleatum subsp. nucleatum and Porphyromonas endodontalis, thus providing strain-level microbiological evidence for infection source tracing in OMS.

Objective:To investigate the neural regulatory mechanism of parvalbumin-positive interneurons(PV-INs)in the dentate gyrus(DG)involved in the impairment of spatial recognition memory by exercise-induced chronic fatigue.Methods:Male Sprague-Dawley(SD)rats were divided into control group and fatigue group by random num-ber method.A three-level incremental load treadmill training program was selected to establish a chronic exhaustion exercise fatigue model.The spatial recognition memory ability of rats was tested by novel object recognition test.The ac-tivation levels and quantitative changes of astrocytes(AS)and PV-INs in the DG region was observed and quantified through immunofluorescence staining and immunohistochemical staining.The phosphorylation level of calcium/calmodu-lin-dependent protein kinase Ⅱ(CaMK Ⅱ)in the hippocampus was detected by Western blot.Results:In the test of novel object recognition,the exploration time of novel object was reduced in the fatigue group,and the discrimination index was significantly lower than that in the control group(P<0.01).Immunohistochemical staining showed that PV-INs in the DG region of fatigue rats were lighter and fewer than those in the control group,the fibers were short and sparse,and the positive cell density and average optical density of cells were significantly lower than those in the control group(P<0.01).Immunofluorescence staining showed that AS was significantly activated,glial fibrillary acidic pro-tein(GFAP)was stained deeply,and the cell processes were dense and elongated in the DG region of fatigue rats.The positive cell density and mean fluorescence intensity were significantly higher than those of the control group(P<0.01).The results of Western blot showed that the phosphorylation level of CaMK Ⅱ protein in the hippocampus of the fatigue group was significantly reduced than that of the control group(P<0.01).Conclusion:Exercise-induced chro-nic fatigue inhibited PV-INs in the rat hippocampal DG region.The excessive activation of AS following exercise fatigue may be a major contributor to this PV-INs suppression.Concurrently,reduced phosphorylation levels of CaMK Ⅱ protein were observed in hippocampal tissue.These alterations ultimately impaired spatial recognition memory in the rats.
