The establishment of core indicators for assessment plays an important role in carrying out the lifecycle value assessment of Chinese patent medicine, which are developed based on the concepts such as clinical value oriented, paying attention to the human use experience, and whole process quality control. To this end, the Specialty Committee of Data Monitoring and Decision Making of the World Federation of Chinese Medicine Societies organized experts to draft the Expert Consensus on Core Indicators for Lifecycle Value Assessment of Chinese Patent Medicine based on the research including Chinese Medicine Registration Review Evidence System in Combination of Traditional Chinese Medicine Theory, Human Use Experience, and Clinical Trials(GZY-FJS-2022-206) by National Administration of Traditional Chinese Medicine. This consensus proposed 92 core indicators from four stages, including new drug R&D project approval, pre-clinical research, new drug marketing authorization, and post-marketing, combining the assessment purposes and needs of different stakeholders from different dimensions such as clinical needs, clinical positioning, human use experience, effectiveness, safety, quality control, innovation, accessibility, and suitability. This consensus also interpreted the indicators to clearly elucidate the core elements of the value assessment of Chinese patent medicine in different R&D stages and guided the stakeholders to identify, analyze, and assess the value of Chinese patent medicine in the R&D and use process based on the core indicators in a scientific, objective, and standardized approach. This consensus is expected to play an important role in the high-quality new drug development, drug pricing and compensation of Chinese patent medicine, the development of clinical pathways, and rational clinical application.

Background and Objectives: Chronic inflammation of bone tissue often results in bone defects and hazards to tissue repair and regeneration. Cannabidiol (CBD) is a natural cannabinoid with multiple biological activities, including anti-inflammatory and osteogenic potential. This study aimed to investigate the efficacy and mechanisms of CBD in the promotion of bone marrow mesenchymal stem cells (BMSCs) osteogenic differentiation in the inflammatory microenvironment. Methods: and Results: BMSCs isolated from C57BL/6 mice, expressed stem cell characteristic surface markers and pre-sented multidirectional differentiation potential. The CCK-8 assay was applied to evaluate the effects of CBD on BMSCs’ vitality, and demonstrating the safety of CBD on BMSCs. Then, BMSCs were stimulated with lipopolysaccharide (LPS) to induce inflammatory microenvironment. We found that CBD intervention down-regulated mRNA expression levels of inflammatory cytokines and promoted cells proliferation in LPS-treated BMSCs, also reversed the protein and mRNA levels downregulation of osteogenic markers caused by LPS treatment. Moreover, CBD intervention activated the cannabinoid receptor 2 (CB2) and the p38 mitogen-activated protein kinase (MAPK) signaling pathway. While AM630, a selective CB2 inhibitor, reduced phosphorylated (p)-p38 levels. In addition, AM630 and SB530689, a selective p38 MAPK inhibitor, attenuated the enhancement of osteogenic markers expression levels by CBD in inflammatory microenvironment, respectively. Conclusions CBD promoted osteogenic differentiation of BMSCs via the CB2/p38 MAPK signaling pathway in the inflammatory microenvironment.

Although there is guidance from different regulatory agencies, there are opportunities to bring greater consistency and stronger applicability to address the practical issues of establishing and operating a data monitoring committee (DMC) for clinical studies of Chinese medicine. We names it as a Chinese Medicine Data Monitoring Committee (CMDMC). A panel composed of clinical and statistical experts shared their experience and thoughts on the important aspects of CMDMCs. Subsequently, a community standard on CMDMCs (T/CACM 1323-2019) was issued by the China Association of Chinese Medicine on September 12, 2019. This paper summarizes the key content of this standard to help the sponsors of clinical studies establish and operate CMDMCs, which will further develop the scientific integrity and quality of clinical studies.

International Regulatory Cooperation for Herbal Medicines (IRCH) was established in 2006, and became an official agency of WHO in 2017. The development history after IRCH founded, organization framework, term of reference, workflow and requirements for joining IRCH, and current priorities of IRCH were systematically introduced. At the same time, combining to the work priorities of IRCH, China should actively participate in the relevant works of IRCH from the following aspects, such as the establishment of international herbal medicine standards, compilation of WHO herbal pharmacopoeia, evidence-based research on herbal medicine, and data information collection of herbal drugs. The participation on IRCH work could contribute to the development of traditional Chinese medicine in the global market.

OBJECTIVE: To investigate the expression of autophagy-related protein Beclin-1 and microtubule-associated protein 2 light chain 3 (LC3Ⅱ) in periodontal ligament cells in orthodontic tooth pressure areas. METHODS: Sixty male SD rats were randomly divided into a blank control group and nine experimental groups. In the experimental groups, 0.392 N orthodontic force was used to move the first right upper molars for 15 min, 30 min, 1 h, 2 h, 4 h, 12 h, 1 d, 3 d, or 7 d. The blank control group did not receive any treatment. The rats were euthanized. Changes in the morphology of the periodontal membrane in the pressure areas were observed through hematoxylin and eosin (HE) staining. The expression levels of Beclin-1 and LC3Ⅱ were detected by immunohistochemical staining, and tartrate-resistant acid phosphatase (TRAP) staining was performed for the counting of osteoclasts. RESULTS: The HE stains showed that the hyalinization of the periodontal ligament appeared in the pressure areas after 1 day of exertion and was gradually aggravated. The immunohistochemical stains showed that the expression levels of Beclin-1 and LC3Ⅱ in the experimental groups gradually increased, peaked after 1 h, and then gradually decreased. The expression levels peaked again after 1 d, then decreased to baseline levels at 7 d of exertion. Beclin-1 and LC3Ⅱ were expressed in the osteoclasts. The TRAP stains indicated that the number of osteoclasts started to increase after 1 day. CONCLUSIONS Autophagy may participate in the process of periodontal ligament reconstruction in orthodontic tooth pressure areas by mediating the hyalinization of periodontal ligament and affecting the biological effects of osteoclasts.

We determined a component-target-disease network for Carthamus tinctorius L. and the key compounds, identified by topological analysis, were related to vasculitis, coronary heart and cerebrovascular disease. Based on these compounds, the chromatographic fingerprint of Carthamus tinctorius L. was established. Firstly, 132 compounds were obtained from TCMID and TCMSP databases. Their targets were predicted in the PharmMapp and HemMapper databases. CardioGenBase, Therapeutic Target Database and DisGeNET databases were used to collect targets of vasculitis, coronary heart disease and cerebrovascular disease. The corresponding relationships between component and target protein were established by mapping. Finally, the "component-target-disease" network was built with Cytoscape software. The core network and key nodes were analyzed with the Cytohubba plug-in. The results showed that the 24 key compounds were alpha-tocopherol, adenosine, quinone chalcone pigments such as hydroxysafflor yellow A, safflower yellow, quercetin, kaempferol and other flavonoids, organic acids such as stearic acid, linolenic acid, coumaric acid and cinnamic acid. This resulting chromatographic fingerprint of Carthamus tinctorius L. showed good consistency, and the core chemical compounds obtained by topological analysis of the network of "component-target-disease", could be used as quality control markers. Our research provides a new approach for the identification of quality control indicators in Chinese medicinal materials.

BACKGROUND: Estrogen can promote the osteogenic differentiation of human periodontal ligament stem cells (hPDLSCs), but the molecular mechanism is unclear. OBJECTIVE:To study the regulatory effect of estrogen on the osteogenic differentiation of hPDLSCs via Wnt/β-catenin signaling pathway. METHODS: The hPDLSCs were isolated and purified by digestion method combined with limited dilution clone method. Three experimental groups were set as follows: osteogenic induction only (control group); 1×10-7mol/L estrogen with osteogenic induction (estrogen group); and 100 μg/L Wnt3a protein with osteogenic induction (Wnt3a group). Alkaline phosphatase activity was detected at 1, 3, 5, 7 days of osteogenic induction. Western blot was used to detect the expression of Wnt/β-catenin signaling pathway related proteins β-catenin, P-GSK-3β, GSK-3β, CyclinD1 and osteoblast-related proteins Runx2 and OCN after 7 days of osteogenic induction. RESULTS AND CONCLUSION: The activity of ALP in all groups increased with time. The expression level of ALP in the estrogen group and Wnt3a group was higher than that in the control group at 1, 3, 5 and 7 days of induction (P < 0.05), while there was no significant difference between the former two groups (P > 0.05). The western blot results showed that the expression levels of β-catenin, P-GSK-3β, CyclinD1, Runx2 and OCN in the estrogen group and Wnt3a group were higher than those in the control group (P < 0.05), while the expression of GSK-3β was lower than that in the control group (P < 0.05). But there were no differences in the expression of Wnt/β-catenin signaling pathway related proteins and mid-late osteogenic markers between estrogen group and Wnt3a group (P > 0.05). To conclude, estrogen can enhance the osteogenic differentiation of hPDLSCs, and the underlying mechanism is likely to activate the Wnt/β-catenin signaling pathway in activated hPDLSCs exposed to estrogen.

Objective To provide new ideas for establishment of prevention and control strategy for non-communicable chronic disease (NCD) that are suitable for Chinese people.

OBJECTIVETo assess the association between 2 single nucleotide polymorphisms (SNPs) of ETS1 gene and susceptibility to systemic lupus erythematosus (SLE) in a northern Chinese Han population.

METHODSTwo SNPs within the ETS1 gene mapped to 11q23 were selected based on HapMap data. Genotyping was conducted with Taqman method in 231 patients with SLE and 474 healthy controls from Qilu Hospital, Shandong and analyzed with PLINK1.07 software. Haplotypes were analyzed with SHEsis software.

RESULTSA statistically significant difference was detected in the distribution of rs1128334 and rs4937333 genotypes between the two groups (all P< 0.01). For rs1128334, the frequency of the minor allele was 0.291 and 0.428 in controls and cases, respectively. For rs4937333, the minor allele frequency was 0.381 and 0.476 in controls and cases respectively. An A-C haplotype was found to be strongly associated with increased risk for SLE, while another haplotype G-C may reduce this risk.

CONCLUSIONOur study has suggested that rs1128334 and rs4937333 are strongly associated with the risk for SLE in northern Chinese Han population.
