Objective: To systematically evaluate the efficacy of scraping therapy on knee osteoarthritis (KOA).

Methods: A computerized search was conducted in several databases, including PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure Database, China Science and Technology Journal Database, Wanfang, and Chinese BioMedical Literature Database, from the establishment date of these databases to April 9, 2023. Randomized controlled trials (RCTs) on scraping therapy for KOA were collected in accordance with the "Participants-Intervention-Control-Outcome-Study design" criteria. The methodological evaluation of the included studies was carried out using RoB 2.0, and Meta-analysis was conducted using RevMan. The Grades of Recommendations Assessment, Development and Evaluation (GRADE System) was applied to grade the quality of evidence.

Results: A total of 12 RCTs with 997 subjects were included in the Meta-analysis. Results indicated that compared with the control group, the scraping therapy treatment group exhibited increased Lysholm scores [mean difference (MD) = 4.96, 95% confidence intervals (CI) (3.18, 6.74), P < 0.000 01] and Hospital for Special Surgery scores [MD= 8.35, 95% CI(3.92, 12.78), P =0.0002] and decreased visual analog scale scores [MD = -2.11, 95% CI(-3.79, -0.44), P =0.01] and Western Ontario and McMaster University Osteoarthritis Index scores [MD= -6.77, 95% CI(-8.99, -4.56), P < 0.000 01)]. The quality of evidence obtained in this Meta-analysis was low according to the GRADE system.

Conclusion: The available evidence suggests that scraping therapy may have certain clinical efficacy in the treatment of KOA. However, further high-quality RCTs are needed to confirm the findings.

Objective: To reveal the potential underlying mechanism of the Shenqi Tiaoshen formula (, SQTS) in the treatment of chronic obstructive pulmonary disease (COPD) by utilizing network pharmacology, molecular docking, and experimental verification.

Methods: Multiple open-source databases and research related to Traditional Chinese Medicine or compounds were employed to screen active ingredients and corresponding potential targets of the SQTS. The protein-protein interaction network screened hub genes, the relevant molecular mechanism and gene regulation were initially identified through the Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) analysis, and molecular docking was used to confirm further the interaction of the main components bound to the core targets. In vivo experiments on the COPD combined Qi-deficiency syndrome rat model were performed to verify the intervention effects and predicted potential molecular mechanisms of the SQTS.

Results: This study selected 156 active compounds and 326 candidate targets for treating COPD. Quercetin, Nobiletin, Kaempferol, Luteolin, Ginsenoside Rh2 and Formononetin were probably the main active compounds of SQTS in COPD treatment as they affected the most COPD-related targets, and interleukin-1 (IL-6), signal transducing activator of transcription 3 (STAT3), matrix metalloproteinase-9 (MMP9), vascular endothelial growth factor A (VEGFA), protein kinase B (AKT1), hypoxia-inducible factor-1α (HIF-1α), and forkhead box O3 (FoxO3) were identified as the hub genes associated with its therapeutic effect. KEGG analysis was mainly enriched in the signaling pathways closely related to inflammation, immunity and oxidative stress, such as HIF-1, tumor necrosis factor (TNF), phosphatidylinositol 3 kinase (PI3K)-AKT, FoxO, apoptosis, IL-17, and toll-like receptor. Molecular docking confirmed that the main active components shared a good affinity with the hub genes. In vivo experiments, the SQTS was found to improve the body weight, exhaustive swimming time, tail-hanging immobility time and struggle times, airway inflammation, lung functions, and inflammatory factors in the rat model of COPD. The up-regulation of p-PI3K, p-AKT, HIF-1α, FoxO3α, toll like receptor 4, VEGFA, Caspase 3, TNF-α, and IL-17 in COPD rats were down-regulated by SQTS, consistent with the network pharmacology results.

Conclusions: This study provides evidence that the SQTS plays a critical role in anti-inflammation via suppressing immune inflammation and oxidative stress related pathways, indicating that the SQTS is a candidate herbal drug for further investigation in treating COPD.

Objective: To analyze the serum metabolic targets of the "Zhibian (BL54) through Shuidao (ST28)" acupuncture technique in cyclophosphamide (CTX)-induced premature ovarian insufficiency (POI) model rats and to elucidate the potential molecular mechanism of acupuncture in improving POI.

Methods: We used an intraperitoneal injection of CTX to establish the POI rat model (POI group) and compared serum hormone levels and ovarian histopathological changes to evaluate the effect of the Zhibian (BL54) through Shuidao (ST28) technique (ZS + POI group) on ovarian function. Then, nontargeted metabolomics was performed using rat serum by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS).

Results: After acupuncture intervention, the serum hormone levels and ovarian pathological morphology of POI rats were effectively improved. Moreover, UPLC-Q-TOF/MS results showed that the ZS + POI group showed a significant reversal of the levels of 6 differential metabolites. Among them, the levels of four serum metabolic markers, divanillyltetrahydrofuran ferulate, trans-ferulic acid, tryptamine, and neuraminic acid, increased significantly. Further analysis of biological effects showed that all metabolites were involved in the regulation of reproductive hormone levels and antioxidant and antiapoptotic effects.

Conclusions: The "Zhibian (BL54) through Shuidao (ST28)" acupuncture method may improve the ovarian function of POI rats by regulating serum metabolite markers to exert antioxidant and antiapoptotic effects, which provides a theoretical basis for the clinical application of acupuncture in the treatment of POI.

Objective: To explore the four Qiof Pfaffia glomerata (PG) and endow this foreign folk herb with the properties of Chinese medicine, make it Chinese medicinal and localized, and could be used as a Chinese medicine.

Methods: The normal group, six cold herb groups, six hot herb groups, six cool herb groups, PG prescription group (PGPG), and Dangshen (Radix Codonopsis) prescription group (CPPG) were prepared with corresponding concentrations of water extracts, these herb extracts were administered by gavage to Sprague-Dawley rats, and the 12 h urine at night on the 29th day of the SD rats in each group were collected, Liquid Chromatograph Mass Spectrometer system was used to analyze them, the best discriminant models for the medicinal properties of cold-hot and cold-cool were set up, so as to the medicinal properties of PGPG, CPPG and PG were predicted. Based on the Progenesis QI, Human Metabolome Database, Kyoto Encyclopedia of Genes and Genomes, MetaboAnalyst 5.0 database, we enriched metabolic pathway and classification mechanism of medicinal properties of cold-cool Chinese herbs and the molecular mechanism of PG prescription.

Results: We established a best model of cold-hot herbal discrimination in the positive ion mode, then the probability that PGPG was predicted cold property was 88.9%. Furthermore, a model of cold-cool herbal discrimination was established, then the probability of PGPG containing the cool property was 77.8%. In addition, typical cold and cool herbs mainly affected nine biomarkers such as tyrosine-proline, (R)-3',7-Dihydroxy-2',4'-dimethoxyisoflavane in rats. The regulation trend of PGPG on markers was basically as same as the cool herbs and mainly involved in regulating the two pathways of cytochrome P450 and purine metabolism.

Conclusion: The results showed PGPG had a cool medicinal property as same as CPPG, and the regulation trend of PGPG on markers was consistent with cool herbs. Therefore, the medicine properties PG and CP should be consistent, and the Traditional Chinese Medicine property of PG was predicted to be neutral.

Objective: To explore the possible regulatory mechanism of microRNA (miRNA) in moxibustion treatment for decreased ovarian reserve (DOR).

Methods: The DOR model was constructed by intragastrical Tripterygium glycoside suspension administration, and moxibustion therapy was simultaneously given. The morphological ovarian changes were observed by hematoxylin and eosin staining. The miRNA expression profile was detected by RNA sequencing, and bioinformatics analysis was performed. Cytoscape software 3.6.1 was used to establish a regulatory network and differentially expressed miRNAs were verified by reverse transcription quantitative polymerase chain reaction (RT-qPCR).

Results: Decreased number of mature follicles, increased atresia follicles, and abnormal granulosa cell morphology were observed in the model group compared with the control group. The moxibustion group demonstrated increased mature follicles, decreased atretic follicles, and significantly decreased abnormal morphology of granulosa cells compared with the model group. Additionally, RNA sequencing results manifested significantly up-regulated miRNA expressions (miR-92b-3p, miR-26-5p_R + 1_1ss10TC, miR-206-3p, miR-9993b-3p_1ss6GA, miR-7857-3p_R-1, miR-219a-2-3p_1ss10GC, miR-3968-p5_1ss10AT, and PC-5p-6478_1795) and down-regulated miR-664-2-5p_R + 1 in the model group, compared with the control group, and the moxibustion group reversed abnormal disorder levels of these miRNAs. Moreover, these differentially expressed miRNAs were mainly involved in the phosphatidylinositol-3-kinase / protein kinase B signaling pathway and nuclear factor erythropoietin-2-related factor 2 / heme oxygenase 1 signaling pathway. Finally, network and RT-qPCR verification revealed miR-9993b-3p_1ss6GA as the most critical miRNA.

Conclusion: This experiment proved the effectiveness of moxibustion in improving the ovarian reserve of rats by regulating miRNA expression, especially miR-9993b-3p_1ss6GA.

Objective: To explore the differences in Traditional Chinese Medicine (TCM) diagnosis and treatment rules for coronavirus disease 2019 (COVID-19) between Northern and Southern China based on the real-world data from 982 COVID-19 patients.

Methods: All consecutive cases of COVID-19 admitted to the TCM department of designated COVID-19 hospitals in eight provinces and cities were retrospectively analyzed. Patients were divided into a Northern and a Southern group according to the location of the admitting hospital. The symptoms, syndrome elements, syndrome distribution and herbal treatments were analyzed. The core prescriptions were extracted using the multiscale backbone-based network comparison algorithm (msbNC).

Results: The distribution of syndrome elements showed that dampness was common in Northern and Southern China, wind and heat were more often present in the South, while fire toxin and spleen deficiency were more often encountered in the North. The distribution of syndromes showed that the South was dominated by heat dampness accumulating in the lung (55.69%), while the North was dominated by dampness-toxin stagnating in the lung (44.90%).The results of core prescription mining showed that dispelling dampness, dispersing wind, clearing heat and strengthening spleen were the common treatment methods in Northern and Southern China. For mild cases, Jinyinhua (Flos Lonicerae) and Lianqiao (Fructus Forsythiae Suspensae) were often used in the South to clear heat and relieve exterior symptoms, while Chaihu (Radix Bupleuri Chinensis) and Huangqin (Radix Scutellariae Baicalensis) were often used in the North to relieve muscles by expelling heat. For moderate cases, Chaihu (Radix Bupleuri Chinensis), Qinghao (Herba Artemisiae Annuae), and Shigao (Gypsum Fibrosum) were often used to clear heat of Tri-jiao Channel and stomach in the South, while Fuling (Poria), Chenpi (Pericarpium Citri Reticulatae), and Dangshen (Radix Codonopsis) were often used to invigorate spleen and remove dampness in the North. For severe cases, spleen invigoration and dampness removal as well as relaxing the bowels and discharging heat were often used in the North.

Conclusion: There were certain North-South differences in terms of symptoms, syndrome elements and syndrome distribution of COVID-19, as well as differences in core prescriptions during different periods of the disease. The regional differences in the rules of TCM diagnosis and treatment for COVID-19 should be further considered in the process of optimization and revision of relevant treatment guidance.

Objective: Exploring the effect of Optimized New Shengmai powder (, ONSMP) on myocardial fibrosis in heart failure (HF) based on rat sarcoma (RAS)/rapidly accelerated fibrosarcoma (RAF)/mitogen-activated protein kinase kinase (MEK)/extracellular regulated protein kinases (ERK) signaling pathway.

Methods: Randomized 70 Sprague-Dawley rats into sham (n = 10) and operation (n = 60) groups, then established the HF rat by ligating the left anterior descending branch of the coronary artery. We randomly divided the operation group rats into the model, ONSMP [including low (L), medium (M), and high (H) dose], and enalapril groups. After the 4-week drug intervention, echocardiography examines the cardiac function and calculates the ratios of the whole/left heart to the rat's body weight. Finally, we observed the degree of myocardial fibrosis by pathological sections, determined myocardium collagen (COL) I and COL Ⅲ content by enzyme-linked immunosorbent assay, detected the mRNA levels of COL I, COL Ⅲ, α-smooth muscle actin (α-SMA), and c-Fos proto-oncogene (c-Fos) by universal real-time, and detected the protein expression of p-RAS, p-RAF, p-MEK1/2, p-ERK1/2, p-ETS-like-1 transcription factor (p-ELK1), p-c-Fos, α-SMA, COL I, and COL Ⅲ by Western blot.

Results: ONSMP can effectively improve HF rat's cardiac function, decrease cardiac organ coefficient, COL volume fraction, and COL I/Ⅲ content, down-regulate the mRNA of COL I/Ⅲ, α-SMA and c-Fos, and the protein of p-RAS, p-RAF, p-MEK1/ 2, p-ERK1/2, p-ELK1, c-Fos, COL Ⅰ/Ⅲ, and α-SMA.

Conclusions: ONSMP can effectively reduce myocardial fibrosis in HF rats, and the mechanism may be related to the inhibition of the RAS/RAF/MEK/ERK signaling pathway.

Objective: To investigate the effects of Hippeastrum hybridum (HH) as a free radical scavenger, and an inhibitor of the two enzymes i-e Alpha-amylase (α-amylase) and acetylcholinesterase (AChE).

Methods: In this study, HH plant was preliminary analyzed for phytochemical screening and then tested for its antioxidant, anti-α-amylase, and anti-AChE efficiency via standard procedures.

Results: Phytochemical analysis shows the existence of different compounds; while Coumarins and quinones were absent. The total phenolic, flavonoid, and tannins content were found to be (78.52 ± 0.69) mg GAE/g, (2.01 ± 0.04) mg RUE/g, and (58.12 ± 0.23) mg TAE/g of plant extract respectively. 28.02% ± 0.02% alkaloid and 2.02% ± 0.05% saponins were present in the HH extract. The HH extract showed the anti-oxidant property with IC50 (50% inhibition) of (151.01 ± 0.13) (HH), (79.01 ± 0.04) (Ascorbic acid) for ferric reducing, (91.48 ± 0.13) (HH), (48.02 ± 0.11) (Ascorbic acid) against Ammonium molybdenum, (156.02 ± 0.31) (HH), (52.38 ± 0.21) (Ascorbic acid) against DPPH, 136.01 ± 0.21 (HH), 52.02± 0.31 (Ascorbic acid) against H₂O₂, and 154.12 ± 0.03 (HH), (40.05 ± 0.15) (Ascorbic acid) μg/mL against ABTS respectively. Statistical analysis indicated that HH caused a competitive type of inhibition of α-amylase (V_max remained constant and Km increases from 10.65 to 84.37%) while Glucophage caused the un-competitive type of inhibition i-e both Km and V_max decreased from 40.49 to 69.15% and 38.86 to 69.61% respectively. The K_i, (inhibition constant); K_I, (dissociation constant), K_m, (Michaelis-Menten constant), and IC50 were found to be 62, 364, 68.1, and 38.08 ± 0.22 for HH and 12, 101.05, 195, 34.01 ± 0.21 for Glucophage. Similarly, HH causes an anon-competitive type of inhibition of AChE i-e Km remains constant while V_max decreases from 60.5% to 74.1%. The calculated K_i, K_I, K_m, and IC50 were found to be 32, 36.2, 0.05, and 18.117 ± 0.018.

Conclusion: From the current results, it is concluded that HH extract contains bioactive compounds, and could be a good alternative to controlling oxidants, Alzheimer's and Type-II diabetic diseases.

OBJECTIVE：To elucidate the mechanism by which Huoxue Jiedu Huayu recipe (, HJHR) regulates angiogenesis in the contralateral kidney of unilateral ureteral obstruction (UUO) rats and the mechanism by which it reduces of renal fibrosis.

Methods: Male Wistar rats were randomly divided into 4 groups: the sham group, UUO group (180 d of left ureter ligation), UUO plus eplerenone (EPL) group, and UUO plus HJHR group. After 180 d of oral drug administration, blood and contralateral kidneys were collected for analysis. Angiogenesis- and fibrosis-related indexes were detected.

Results: HJHR and EPL improved structural damage and renal interstitial fibrosis in the contralateral kidney and reduced the protein expression levels of α-smooth muscle actin (α-SMA), vimentin and collagen I. Moreover, these treatments could reduce the expression of vascular endothelial growth factor-A (VEGFA) by inhibiting the infiltration of macrophages. Furthermore, HJHR and EPL significantly reduced the expression of CD34 and CD105 by downregulating VEGFA production, which inhibited angiogenesis. Finally, the coexpressions of CD34, CD105 and α-SMA were decreased in the HJHR and EPL groups, indicating that endothelial-to-mesenchymal transition was inhibited.

Conclusions: These findings confirm that HJHR alleviates contralateral renal fibrosis by inhibiting VEGFA-induced angiogenesis, encourage the use of HJHR against renal interstitial fibrosis and provide a theoretical basis for the clinical management of patients with CKD.

Objective: To evaluate the quality of Moyao (Myrrh) in the identification of the geographical origin and processing of the products.

Methods: Raw Moyao (Myrrh) and two kinds of Moyao (Myrrh) processed with vinegar from three countries were identified using near-infrared (NIR) spectroscopy combined with chemometric techniques. Principal component analysis (PCA) was used to reduce the dimensionality of the data and visualize the clustering of samples from different categories. A classical chemometric algorithm (PLS-DA) and two machine learning algorithms [K-nearest neighbor (KNN) and support vector machine] were used to conduct a classification analysis of the near-infrared spectra of the Moyao (Myrrh) samples, and their discriminative performance was evaluated.

Results: Based on the accuracy, precision, recall rate, and F1 value in each model, the results showed that the classical chemometric algorithm and the machine learning algorithm obtained positive results. In all of the chemometric analyses, the NIR spectrum of Moyao (Myrrh) preprocessed by standard normal variation or Multivariate scattering correction combined with KNN achieved the highest accuracy in identifying the geographical origins, and the accuracy of identifying the processing technology established by the KNN method after first-order derivative pretreatment was the best. The best accuracy of geographical origin discrimination and processing technology discrimination were 0.9853 and 0.9706 respectively.

Conclusions: NIR spectroscopy combined with chemometric technology can be an important tool for tracking the origin and processing technology of Moyao (Myrrh) and can also provide a reference for evaluations of its quality and the clinical use.
