AIM:To detect the changes of active status of bypass signaling pathways in EML4-ALK positive lung cancer cell line H3122 treated with alectinib, hepatocyte growth factor (HGF), epidermal growth factor (EGF) and transforming growth factor-α (TGF-α), and to explore the potential mechanisms.METHODS:EML4-ALK positive cell line H3122 was treated with increasing concentrations of alectinib or/and induced by HGF, EGF and TGF-α.The cell viability was measured by CCK-8 assay.The cell apoptosis was analyzed by flow cytometry.The protein levels and phosphorylation status of ALK, c-Met and EGFR, and the downstream molecules AKT, ERK, p-AKT and p-ERK were examined by Western blot.RESULTS:The viability of the H3122 cells was inhibited by alectinib in a dose-dependent manner after administrated for 72 h, and the IC50 value was 0.042 μmol/L.The concentration-growth curves of the H3122 cells shifted to the right after induced by HGF, EGF and TGF-α.After treatment with alectinib at 0.05 μmol/L for 48 h, the apoptotic rate of H3122 cells was (20.12±1.36)%, while the apoptotic rates of the cells in the groups of alectinib combined with HGF, EGF or TGF-α were (7.85±1.03)%, (5.60±0.79)% and (4.58±1.00)%, respectively.Those values were remarkably lower than those in alectinib single treatment group (P<0.05).Alectinib inhibited the protein levels of p-ALK and its downstream signaling pathway molecules, while HGF significantly up-regulated the protein levels of p-Met and its downstream p-AKT and p-ERK.Besides, EGF and TGF-α remarkablely up-regulated the protein levels of p-EGFR and its downstream p-AKT and p-ERK.Combined treatment with crizotinib and 17-DMAG successfully inhibited the viability of the H3122 cells even in the presence of the HGF and EGFR ligands, respectively.CONCLUSION:Bypass signaling pathways are activated by HGF, EGF and TGF-α in EML4-ALK positive lung cancer cell line H3122, which may be linked to alectinib resistance.

OBJECTIVETo investigate the changes in the structure and function of the carotid artery and their relationship with subclinical inflammation in patients with H-type hypertension.
METHODSSixty patients with H-type hypertension and 49 with non-H-type hypertension were enrolled in this study, with 20 healthy volunteers as the control group. All the subjects underwent color Doppler ultrasound examination of the carotid artery, and their blood levels of hyper-sensitive C-reactive protein (hs-CRP), fibrinogen (FIB), and tumor necrosis factor-α (TNF-α) were measured to investigate the correlation between the structural and functional changes of the carotid artery and the inflammatory factors.
RESULTSNo significant difference was found in the blood pressure level between the H-type and non-H-type hypertension groups (136.0∓10.1 vs 131.9∓7.0 mmHg for systolic blood pressure, P>0.05; 80.9∓8.9 vs 73.2∓7.9 mmHg for diastolic pressure, P>0.05). The intima-media thickness, distensibility of the common carotid artery, carotid artery stiffness, and blood homocysteine level all showed significant differences between patients with H-type and non-H-type hypertension (1.52∓0.08 vs 1.09∓0.06 mm, 0.23∓0.14 mmHg(-1)×100 vs 0.46∓0.14 mmHg(-1)×100, and 15.37∓5.89 vs 8.19∓4.53 µmol/L, respectively, P<0.05). The H-type hypertensive patients showed significantly higher hs-CRP, FIB, and TNF-α levels than the non-H-type hypertensive patients, and these inflammatory factors were positively correlated with the structural and functional changes of the carotid artery.
CONCLUSIONThe patients with H-type hypertension are more likely to have carotid artery structure and function impairments, which closely correlate with the subclinical inflammatory factors. These changes might be attributed to the synergism of subclinical inflammation and hyperhomocysteinemia, for which active intervention may prove beneficial.

ObjectiveTo investigate the clinical efficacy and mechanisms of Osteoking in the treatment of knee osteoarthritis (KOA) in real-world practice, so as to provide a basis for the rational clinical use of Osteoking. MethodFrom the Osteoking for knee osteoarthritis case registration system, 638 KOA cases treated with Osteoking were selected and analyzed in SPSS 26.0. The clinical data were collected from 20 hospitals in China from May 2020 to December 2021. Descriptive analyses of patient age, gender, body mass index, course of treatment and other parameters were performed. The Mann-Whitney U test was performed to compare the visual analogue scale (VAS) and Western Ontario and McMaster universities arthritis index (WOMAC) scores before and after treatment. The integrative pharmacology-based research platform of traditional Chinese medicine (TCMIP) v2.0 was used for network analysis of the core targets of Osteoking in treating knee osteoarthritis. Furthermore, 20 KOA patients treated with Osteoking in the Third Affiliated Hospital of Beijing University of Chinese Medicine from October to December in 2022 were enrolled in the treatment group, and 20 healthy volunteers in the control group. The enzyme-linked immunosorbent assay was employed to measure the serum levels of related indicators to verify the prediction results. ResultA total of 638 KOA patients were treated with Osteoking, including 429 (67.24%) receiving Osteoking alone and 209 (32.76%) receiving Osteoking combined with other therapies. The female patients (415, 65.05%) were more than the male patients (223, 34.95%). The patients showed the mean age of (63.48±13.51) years, mean body mass index of (24.09±2.98) kg·m-2, and mean course of treatment of (15.78±9.66) days. Most of the patients were rated as grades Ⅱ (46.24%) and Ⅲ (34.64%) in Kellgren-Lawrence (K-L) grading and in the relief stage (82.45%) in clinical staging. There was no significant correlation between clinical staging and K-L grading results. The cluster analysis identified three TCM syndromes: Qi stagnation and blood stasis, cold-dampness obstruction, and liver-kidney deficiency. The overall clinical efficacy evaluation showed that VAS score decreased from (6.01±0.85) scores before treatment to (2.54±1.73) scores after treatment (P<0.05), and the WOMAC score decreased from (93.25±25.91) scores before treatment to (50.73±25.14) scores after treatment (P<0.05). The network analysis predicted that Osteoking might regulate the transforming growth factor-beta (TGF-β), tumor necrosis factor-alpha (TNF-α), and nuclear factor-kappa B (NF-κB) signaling pathways to exert the therapeutic effect. The clinical trial showed elevated TGF-β1 level (P<0.01) and lowered NF-κB subunit RELA and tumor necrosis factor receptor superfamily, member 1A (TNFRSF1A) levels (P<0.05) after treatment. The synergistic effects of these changes provide a multidimensional and comprehensive therapeutic efficacy for KOA, alleviating the joint pain and limited mobility in patients. ConclusionOsteoking showed significant therapeutic efficacy in treating KOA. Osteoking may act on multiple pathways involved in cartilage metabolism and inflammation. The findings provide experimental evidence and theoretical support for elucidating the multi-target mechanism of Osteoking in treating KOA.

ObjectiveTo investigate the improvement of the efficacy of Osteoking in patients with knee osteoarthritis in the onset and remission stage and to systematically explore its potential intervention mechanism, so as to provide a certain reference for improving the clinical application value of Osteoking and guiding its clinical rational drug use. MethodThrough the real-world study of the treatment of knee osteoarthritis with Osteoking, the data was obtained and entered into the "Osteoking for the treatment of knee osteoarthritis case registration system", and 105 patients with episodic and remission knee osteoarthritis from the outpatient or inpatient orthopedic department of 20 medical institutions, including the Third Affiliated Hospital of Beijing University of Chinese Medicine, Peking Union Medical College Hospital, Wangjing Hospital of the Chinese Academy of Chinese Medical Sciences and Hunan Aerospace Hospital, from May 1, 2020 to December 31, 2021, were selected in the system. It included 60 patients treated with Osteoking and joint injection, and 45 patients treated with joint injection alone. The WOMAC osteoarthritis index score, visual analogue (VAS) pain score, individual types of pain symptoms (cold pain, hot pain, tingling, dull pain, soreness) and other TCM symptoms were observed and compared between the two groups, and statistically analyzed. In order to further elucidate the potential molecular mechanism of Osteoking combined with joint injection in the treatment of knee osteoarthritis in the treatment of onset and remission, this study used the "Bone Injury Cross Database (

ObjectiveTo explore the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis based on real-world data and provide a basis for clinical medication. MethodFrom May 2020 to December 2021, the data of a total of 1 002 patients with knee osteoarthritis who did not undergo knee joint replacement surgery was collected through the registration method. 952 patients were ultimately included, including 133 cases orally taking Osteoking combined with non-steroidal anti-inflammatory drugs as the observation group and 73 cases orally taking non-steroidal anti-inflammatory drugs alone as the control group. Statistical analysis was conducted on the baseline data, VAS scores, WOMAC scores, and other items. The visit point is the 4th and 8th weeks after registration. In order to further elucidate the clinical efficacy of Osteoking combined with non-steroidal anti-inflammatory drugs in the treatment of knee osteoarthritis, the effective components of Osteoking and the relevant gene sets of non-steroidal anti-inflammatory drugs and knee osteoarthritis were obtained through network pharmacology methods and retrieval in bone injury cross database, TCMSP, and other databases. Venn analysis was performed on the relevant gene sets, and a PPI network diagram was constructed. Then key core targets were screened out, and enrichment GO and KEGG enrichment analyses were conducted. ResultThe VAS score of the observation group decreases by an average of (-2.79±1.206) scores in the 4th week, which is better than the control group [(-2.73±1.575) scores, P<0.05]. The VAS score of the observation group decreases by an average of (-3.97±1.308) scores in the 8th week, which is better than the control group [(-3.89±1.822) scores, P<0.05]. The total WOMAC score of the observation group decreases by an average of (-52.07±21.677) scores points in the 8th week, which is significantly better than the control group [(-46.75±25.368) scores, P<0.05]. The observation group has an average decrease of (-10.99±4.229) scores in WOMAC (pain) score in the 8th week, which is better than the control group [(-10.03±5.535) scores, P<0.05]. The observation group has an average decrease of (-1.49±2.901) in WOMAC (stiffness) score in the 4th week, which is better than the control group [(-0.92±1.998) scores, P<0.05], and the observation group has an average decrease of (-1.90±3.200) scores in WOMAC (stiffness) score in the 8th week, which is better than the control group [(-1.26±2.230) scores, P<0.05]. The observation group shows an average decrease of (-39.17±16.562) scores in WOMAC (joint function) score in the 8th week, which is significantly better than the control group [(-35.47±20.098) scores, P<0.05]. According to network pharmacology analysis, the core network target of Osteoking in treating knee osteoarthritis is manifested as regulating signal pathways such as signal transduction transcription activator 3(STAT3), vascular endothelial growth factor A(VEGFA), tumor necrosis factor (TNF) to regulate cell signaling, angiogenesis, chondrocyte proliferation and migration, and inflammatory cells, thereby inhibiting inflammatory reactions, reducing damage, and delaying the development of the disease. ConclusionAfter a 4-week and 8-week course of treatment for knee osteoarthritis with Osteoking combined with non-steroidal anti-inflammatory drugs, there is a significant therapeutic effect on relieving pain and joint stiffness and improving joint function. In network pharmacology, Osteoking is involved in regulating inflammatory factors, metabolic response-related biological processes, the proliferation and apoptosis of chondrocytes, etc. in the treatment of knee osteoarthritis, resulting in anti-inflammatory and analgesic effects and improving joint mobility and joint stiffness. Therefore, it is worthy of clinical promotion and application.
