Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

BACKGROUND: Lead is a persistent inorganic environmental pollutant with global implication for human health. Among the diseases associated with lead exposure, the damage to the central nervous system has received considerable attention. It has been reported that long-term lead exposure increases the risk of meningioma; however, the underlying mechanism remains poorly understood. Clinical studies have indicated that loss-of-function and mutations in the neurofibromin-2 (NF2) gene play a crucial role in promoting meningioma formation. METHODS: The effect of Pb on meningioma were tested in-vitro and in-vivo. Two human meningioma cell lines were used in this study, including NF2-wildtype IOMM-Lee cell and NF2-null CH157-MN cell. Cell viability, cell cycle and cell size were examined after Pb exposure. The expression of Merlin, mammalian sterile 20-like kinases 1 and 2 (MST1/2) and Yes-associated protein (YAP) from these two meningioma cells were analyzed by Western blot. A xenograft mouse model was constructed by subcutaneous injection of IOMM-Lee meningioma cells. RESULTS: This study demonstrated that treatment with lead induce dose-dependent proliferation in IOMM-Lee cell (with an EC₅₀ value of 19.6 µM). Moreover, IOMM-Lee cell exhibited augmented cell size in conjunction with elevated levels of phosphorylated histone H3, indicative of altered cell cycle progression resulting from lead exposure. However, no significant change was observed in the CH157-MN cell. Additionally, the Merlin-Hippo signaling pathway was inactivated with decreased Merlin and phosphorylation levels of MST1/2 and YAP, leading to increased YAP nuclear translocation in IOMM-Lee cells. However, there was no change in the Merlin-Hippo signaling pathway in CH157-MN cells after lead treatment. The administration of Pb resulted in an acceleration of the subcutaneous IOMM-Lee meningioma xenograft growth in mice. CONCLUSIONS Overall, the current study elucidates the potential mechanism by which lead exposure promotes the proliferation of meningioma with NF2 expression for the first time.

ObjectiveKaroshi, death from overwork, is a serious problem with unclear identification standards and mechanisms. This study aims to establish a karoshi rat model by integrating weight-bearing swimming and sleep deprivation. This model will enable us to investigate the adverse effects of acute physical and mental fatigue on cardiac functions and explore the response mechanisms to overwork using integrated omics approaches, specifically metabonomics and proteomics. MethodsThe experimental design involved healthy male sprague-dawley (SD) rats subjected to weight-bearing swimming and sleep deprivation for 7 d. The rats were monitored for changes in physiological function indexes, including electrocardiogram and respiration. Protein digestion, iTRAQ labeling, and quantitative data analyses were performed to determine differentially expressed proteins (DEPs). Additionally, GC-MS analysis was conducted to identify differential metabolites. The integration analysis of differential metabolites and proteins shared by the fatigue group and the overwork group was performed to construct a relevant metabolic pathway network and integrate the proteomics and metabolomics data. Statistical analysis was carried out using one-way ANOVA and Duncan’s multiple range t-tests. ResultsThe rats subjected to weight-bearing swimming and sleep deprivation showed various physical and behavioral changes associated with fatigue, including hair disorder, decreased muscle tension, reduced food intake, and weight loss. Analysis of cardiac functions revealed cardiac hypertrophy and heart failure in the fatigue and karoshi groups, as evidenced by changes in heart color, myocardial fiber structure, heart rate, respiratory rate, and cardiac ultrasound measurements. Metabolomics analysis using GC-MS identified several differential metabolites in response to overwork, including amino acids involved in various metabolic pathways. Proteomic analysis using iTRAQ technology identified DEPs in the fatigue and karoshi groups, with a subset of DEPs shared by both groups. The GO analysis revealed that the up-regulated DEPs were primarily associated with mitochondria and peroxisomes in the cellular component category. The Reactome analysis further highlighted the enrichment of DEPs in the transfer of ferriheme from methemoglobin to hemopexin pathway. Integration analysis of the DEPs and differential metabolites revealed the activation of autophagy, increased mitochondrial oxidative phosphorylation, enhanced branched-chain amino acid degradation, and altered peroxisomal β-oxidation. These findings suggested complex metabolic adaptations to meet the increased energy demands during overwork while also dealing with oxidative stress. Furthermore, the reprogramming of energy metabolism was observed, with upregulation of fatty acid β-oxidation enzymes and glycolysis-related enzymes in the fatigue group, indicating a shift towards glucose metabolism. In contrast, the karoshi group showed a decreased dependence on fatty acids as an energy source and increased utilization of glucose. The model proposed in this study highlights the interconnected metabolic changes involving mitochondria, peroxisomes, and lysosomes in response to overwork. The findings contribute to our understanding of the mechanisms involved in overwork-related pathologies and provide a basis for further research in the field of karoshi. ConclusionOverall, metabolic reprogramming might provide sufficient energy to the heart, alleviate oxidative stress and damage to cardiac cells in response to excessive exertion and fatigue. Our findings provide an insight into response mechanism to overwork death and lay a foundation for further research on overwork death.

The comparison between traditional Chinese medicine Jinzhen oral liquid (JZOL) and Western medicine in treating children with acute bronchitis (AB) showed encouraging outcomes. This trial evaluated the efficacy and safety of the JZOL for improving cough and expectoration in children with AB. 480 children were randomly assigned to take JZOL or ambroxol hydrochloride and clenbuterol hydrochloride oral solution for 7 days. The primary outcome was time-to-cough resolution. The median time-to-cough resolution in both groups was 5.0 days and the antitussive onset median time was only 1 day. This randomized controlled trial showed that JZOL was not inferior to cough suppressant and phlegm resolving western medicine in treating cough and sputum and could comprehensively treat respiratory and systemic discomfort symptoms. Combined with clinical trials, the mechanism of JZOL against AB was uncovered by network target analysis, it was found that the pathways in TRP channels like IL-1β/IL1R/TRPV1/TRPA1, NGF/TrkA/TRPV1/TRPA1, and PGE2/EP/PKA/TRPV1/TRPA1 might play important roles. Animal experiments further confirmed that inflammation and the immune regulatory effect of JZOL in the treatment of AB were of vital importance and TRP channels were the key mechanism of action.

Objective: To investigate whether tanshinone ⅡA can protect the apoptosis of mice cochlear pericytes induced by high glucose and its specific protective mechanism, so as to provide experimental evidence for the prevention and treatment of diabetic hearing loss. Methods: C57BL/6J male mice were used to prepare type 2 diabetes model, which were divided into normal (NG) group, diabetic (DM) group, diabetic+tanshinone ⅡA (HG+tanshinone ⅡA) group and tanshinone ⅡA group. Each group had 10 animals. Primary cochlear pericytes were divided into NG group, HG group (high glucose 35 mmol/L), HG+tanshinone ⅡA (1, 3, 5 μmol/L) group, HG+Tanshinone ⅡA+LY294002 (PI3K/AKT pathway inhibitor) group, LY294002 group, tanshinone ⅡA group and DMSO group. Auditory brainstem response (ABR) was used to measure hearing threshold. Evans blue was used to detect the permeability of blood labyrinth barrier in each group. TBA methods were used to detect oxidative stress levels in various organs of mice. Morphological changes of stria vascularis were observed by hematoxylin-eosin staining (HE). Evans blue was used to detect the vascular labyrinth barrier permeability in cochlea. The expression of apoptosis protein in stria vascularis pericytes was observed by immunofluorescence. Pericytes apoptosis rate was observed by flow cytometry. DCFH-DA was combined with flow cytometry to detect intracellular ROS content, and Western blot was used to detect the expression of apoptotic proteins (Cleaved-caspase3, Bax), anti-apoptotic proteins (BCL-2) and pathway proteins (PI3K, p-PI3K, AKT, p-AKT). SPSS software was used for statistical analysis. Independent sample t test was performed, and P<0.05 was considered statistically significant. Results: Animal experiments: Tanshinone ⅡA decreased the hearing threshold of DM group [(35.0±3.5) dB SPL vs. (55.3±8.1) dB SPL] (t=4.899, P<0.01), decreased the oxidative stress level in cochlea (t=4.384, P<0.05), improved the structure disorder, atrophy of cochlea vascular lines, vacuole increased phenomenon. Tanshinone ⅡA alleviated the increased permeability of the blood labyrinth barrier [Evans blue leakage (6.84±0.27) AU vs. (8.59±0.85) AU] in the cochlea of DM mice (t=2.770, P<0.05), reversed the apoptotic protein: Caspase3 (t=4.956, P<0.01) and Bax (t=4.388, P<0.05) in cochlear vascularis. Cell experiments: Tanshinone ⅡA decreased intracellular ROS content in a concentration-dependent way (t=3.569, P<0.05; t=4.772, P<0.01; t=7.494, P<0.01); Tanshinone ⅡA decreased apoptosis rate and apoptotic protein, and increased the expression of anti-apoptotic protein, p-PI3K/PI3K and p-AKT/AKT in concentration-dependent manner (all P values<0.05); LY294002 reversed the protective effect of tanshinone ⅡA on pericytes apoptosis (all P values<0.05). Conclusion: Tanshinone ⅡA can inhibit the apoptosis of cochlear pericytes induced by high glucose by reducing oxidative stress level and activating PI3K/AKT signaling pathway under high glucose environment, thus playing a protective role in diabetic hearing loss.

Short-term intermittent fasting (IF) is beneficial to weight control in patients with nonalcoholic fatty liver disease, but the impact of long-term IF is not clear. In this study, healthy C57BL/6N mice with 4-month alternate day fasting (ADF) were used to study the effects of long-term IF on systemic and liver lipid metabolism. The results showed that, compared with the Ad Libitum group, the weight and food conversion rate of mice in the ADF group were markedly decreased and increased respectively, and the liver index and the liver content of triglyceride were significantly increased by pathological examination. qRT-PCR analysis revealed that the mRNA expression of the lipogenesis gene Pparγ and lipolysis gene Atgl was up-regulated in the ADF group (P < 0.05). Western blot analysis showed that the ratio of microtubule associated protein LC3-II/LC3-I was increased, while the abundance of autophagy adaptor protein p62 was decreased in the ADF group. In addition, autophagy signal positive regulation key factor AMPK phosphorylation was increased (P < 0.05), and negative regulation factor mTOR phosphorylation was decreased (P < 0.05) in the ADF group, indicating that hepatocyte autophagy activity was elevated. Taken together, ADF for 4 months results in an excessive liver triglyceride accumulation, accompanied by a marked decrease in liver mTOR phosphorylation and a significant increase in hepatic autophagy.

Objective: To compare the detection rate of advanced neoplasia and the number of people needing endoscopy in colorectal cancer screening giving at different starting age in population at high risk. Methods: Based on the screening project of early diagnosis and treatment of colorectal cancer in Jiashan county, Zhejiang province, two rounds of colorectal cancer screening were conducted between January 2007 and December 2020. After excluding participants who were not at high risk or had incomplete information, 27 130 participants and 31 205 participants were finally enrolled in round one and in round two, respectively. The spline analysis based on the generalized additive model was used to describe the trend of detection rate of advanced neoplasia with age. The detection rate and number of people needing endoscopy for the groups with starting age at 50, 45 and 40 years were calculated, and the differences in the detection rate were tested by χ² goodness of fit test. Results: A total of 21 077 (77.69%) participants in round one and 25 249 (80.91%) participants in round two received endoscopy, in whom 1 097 (detection rate=52.05‰) and 1 151 (detection rate=45.59‰) had advanced neoplasia (cancers and advanced adenomas), respectively. The detection rate increased significantly with age, and the detection rate in round one were significantly higher than that in round two (P<0.05). The overall detection rates of advanced neoplasia for the groups with starting age at 50, 45 and 40 years were 61.11‰, 56.14‰ and 52.05‰ in round one, and 49.10‰, 46.75‰ and 45.59‰ in round two, respectively. The rates were significantly higher for the group with starting age at 50 years than that with starting age at 40 years in both round one and round two (P<0.05). The numbers of people needing endoscopy of advanced neoplasia for the groups with starting age at 50, 45 and 40 years were 17, 18, and 20 in round one, and 21, 22 and 22 in round two. Conclusions: The detection rate of advanced neoplasia increased with age. Starting screening at lower age might contribute to decreased detection rate and increased number of people needing endoscopy. However, the difference was limited.
