OBJECTIVE To evaluate the cost-effectiveness of iruplinalkib for ALK-positive non-small cell lung cancer （NSCLC） patients who had not previously received ALK-tyrosine kinase inhibitors （TKIs） from the perspective of the Chinese healthcare system. METHODS Based on the INSPIRE clinical trial， a three-health state partitioned survival model was developed to simulate the progression of disease， with model cycle of 3 weeks and a life-year time range of 15 years； the discount rate was 5%. For the treatment of ALK-positive advanced NSCLC， total cost， quality-adjusted life year （QALY）， and incremental cost- effectiveness ratio （ICER） were compared between iruplinalkib and crizotinib； using 1-3 times China’s per capita gross domestic product （GDP） （89 358-268 074 yuan） in 2023 as the willingness-to-pay （WTP） threshold， the cost-effectiveness of two regimens were compared. The sensitivity analysis and scenario analysis （altering the distribution of survival curves， utility values） were conducted to assess model robustness. RESULTS Compared with the crizotinib regimen， the ICER for the iruplinalkib regimen was 194 412.74 yuan/QALY， which was below the WTP threshold of three times China’s per capita GDP in 2023 yuan）. The results under the scenario of altering the survival curve distribution were consistent with the base case analysis. However， after increasing the utility value of the disease progression state， the ICER exceeded the WTP threshold， and iruplinalkib no longer had a cost-effective advantage. The results of the one-way sensitivity analysis indicated that the cost of iruplinalkib and the utility values of disease progression states had a significant impact on the ICER. The probabilistic sensitivity analysis confirmed the robustness of the base case analysis results. CONCLUSIONS From the perspective of China’s healthcare system， compared with crizotinib regimen， the therapy with iruplinalkib is cost-effective for ALK-positive NSCLC patients who have not previously received ALK-TKIs.

Objective·To compare the prognostic effects of radical resection of esophageal cancer,concurrent chemoradiotherapy and simple follow-up observation on the prognosis of patients with T1b invasion of superficial esophageal squamous cell carcinoma after endoscopic submucosal dissection(ESD).Methods·From May 2016 to May 2021,the clinical data of 67 patients with esophageal squamous cell carcinoma who were pathologically confirmed as pT1b after ESD and treated in Shanghai Chest Hospital were retrospectively analyzed.According to the additional treatment after ESD,the patients were divided into additional surgery group(S group),chemoradio-therapy group(CRT group)and observation group(O group).χ2 test was used to compare the clinical baseline data and pathological information of the three groups of patients.The Kaplan-Meier survival curve and log-rank test were used to compare the disease free survival(DFS)and recurrence free survival(RFS)of the three groups of patients,and the Cox proportional hazards regression model was used on DFS and RFS by univariate and multivariate analysis.Results·Among all 67 patients,there were 23 cases in the S group,19 cases in the CRT group,and 25 cases in the O group.There was no significant difference in age(P=0.080),gender(P=0.078),tumor length(P=0.485),tumor location(P=0.655),lesion circumferential ratio(P= 0.310),histological grading(P=0.084),depth of tumor invasion(P=0.066)and lymphovascular invasion(P=0.279)among the three groups.During(42.6±16.7)months of follow-up,tumor recurrence was observed in 10 cases(14.9%),including 6 patients(60%)with local recurrence,2 patients(20%)with regional lymph recurrence and 2 patients(20%)with distant metastasis.The median recurrence time of group S,group CRT,and group O was 40.1,36.6,and 22.1 months,and the 3-year DFSs were 100%,89.5%,and 74.5%(P-trend=0.040).Multivariate Cox analysis showed that additional esophagectomy was the key to improving independent protective factors of RFS(HR=0.097,95%CI 0.010?0.956,P=0.046).Conclusion·For patients with superficial esophageal squamous cell carcinoma confirmed as pT1b after ESD,additional surgery can significantly reduce the possibility of long-term recurrence.

Objective:To explore the effects of hinokiol on the cell cyle and apoptosis of CNE1 nasopharyngeal carcinoma cells and the relevant molecular mechanism.Methods:The CNE1 cells were cultured in vitro and incubated with different concentrations of honokiol, and the cells were divided into blank control group, 10 μmol/L, 20 μmol/L and 40 μmol/L hinokiol treatment groups, and 10 μg/ml cisplatin group. Cell viability was determined by methylthiazolyldiphenyl- tetrazolium bromide (MTT) method, the cell cycle distribution was detected by flow cytometry, mitochondrial membrane potential was detected by mitochondrial membrane potential test kit, apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP nick end labeling (TUNEL) method, and the proteins expression of proliferating cell nuclear antigen (PCNA) and G 1/S specific cyclin D1 (cyclin D1) were detected by immunoblotting. RNA-Seq was conducted in the hinokiol-treated cells. The mRNA expression of yes-associated protein delta (YAP) was detected by quantitative reverse transcription polymerase chain reaction (RT-qPCR). The proteins expression of phosphor-YAP (p-YAP) and nuclear YAP were detected by immunoblotting, the nuclear distribution of YAP protein was detected by immunofluorescence in the cells with or without treated with the mammalian STE20-like kinase 1/2 (MST1/2) inhibitor (XMU-MP-1), hinokiol, and XMU-MP-1+hinokiol. Statistical analysis of the data was conducted using GraphPad Prism 8.0 software. Resluts Compared with the control group, the cell viablity of CNE1 cells, the levels of mitochondrial membrane potential, the proteins expression of PCNA and cyclin D1 in hinokiol treatment groups were markedly decreased (all P values<0.05), while the proportion of G 0/G 1 phase cells and the ratio of TUNEL-positive cells were significantly increased (both P values<0.05). Transcriptome analysis showed that differential genes were mainly enriched in Wnt signaling pathway, tumor necrosis factor pathway, and Hippo signaling pathway. The mRNA level of YAP and the protein expression of YAP in the nucleus were decreased and the level of p-YAP protein was increased in cells treated with hinokiol, which were significantly different from control group (all P values<0.05). Compared with the hinokiol group, XMU-MP-1+hinokiol groups showed the decrease of p-YAP protein expression (1.157±0.076 vs 0.479±0.038, t=37.120, P<0.05), the increase of YAP protein expression in the nucleus (0.143±0.012 vs 0.425±0.031, t=29.181, P<0.05), the reduced proportion of cells in G 0/G 1 phase [(72.494±3.309)% vs (58.747±2.865)%, t=17.265, P<0.05], and the decrease of apoptosis ratio [(53.158±3.376)% vs (29.621±2.713)%, t=28.584, P<0.05]. Conclusion:Hinokiol can arrest the cell cycle and induce the cell apoptosis of CNE1 cells via Hippo/YAP signaling pathway.

In recent years， the potential anti-tumor effects of metformin have attracted widespread attention in the field of cancer treatment. This article summarizes the research progress of metformin in the treatment of malignant tumors，finding its potential application in the treatment of malignant tumors in the digestive system （biliary tract cancer，gastric cancer，esophagus cancer，colorectal cancer，pancreatic cancer，liver cancer） and reproductive system （prostate cancer，ovarian cancer，breast cancer， cervical cancer），non-small cell lung cancer，renal cell carcinoma，and melanoma. Metformin can inhibit the proliferation of tumor cells and extend the overall survival of patients. Its mechanisms of action include，but are not limited to，inhibiting the activity of mitochondrial complex Ⅰ，activating adenosine monophosphate-activated protein kinase/p53 signaling pathway，and blocking the cell cycle. Additionally，the combined use of metformin with chemotherapy drugs has shown potential for reducing toxicity and enhancing efficacy. It can enhance the sensitivity of biliary tract cancer，ovarian cancer，and melanoma cells to chemotherapy drugs， improve the drug resistance of gastric and colorectal cancer cells to chemotherapy，and reduce the toxic reactions of breast cancer patients during chemotherapy. Metformin is also used as an immunomodulator，applied in the immunotherapy of patients with esophagus cancer，colorectal cancer，cervical cancer，non-small cell lung cancer，and melanoma.

Objective:To observe the effect of metformin on intestinal metabolites and its protective effect on lung injury in an elderly sepsis rat.Methods:SD rats were fed at the Animal Laboratory Center of Zhengzhou University, fourteen elderly SD rats were randomly divided into three groups: sham surgery (age-Sham, AgS group, n=4), cecal ligation and perforation induced sepsis (age-Cecal ligation and puncture, AgCLP group, n=5), and oral administration of metformin (100 mg/kg) after 1 h of CLP treatment (age-Metformin, AgMET group, n=5). Collected rat feces 24 h after modeling, and analyzed the composition and inter group differences of metabolites in the feces using liquid chromatography tandem mass spectrometry non targeted metabolomics. Collected rat lung tissues and detected the expression levels of inflammation related genes and pathological changes in the tissue. The visualization of metabolic changes between groups were presented using orthogonal partial least squares discriminant analysis, heatmaps, and unsupervised principal component analysis, respectively. MetaboAnalyst 3.0 was used to evaluate the Pathway analysis of metabolites, and this software was based on the KEGG database and the human metabolome database. Results:The expressions of CCL4 ( F=203.00, P<0.001), CXCL1( F=65.69, P<0.001), IL-6 ( F=38.94, P<0.002), TNF-α ( F=14.85, P=0.005) between two groups of rats were significantly different (all P<0.05). However, there was no significant difference in CCL2 expression between AgCLP group and AgMET group. Furthermore, compared with the AgS group, the relative intensities of 17 metabolites such as 7-methylxanthine, N-Arachidonylglycine and Manolide in AgCLP group were significantly increased, whereas the 9 metabolites such as Phenazone, Gly-Phe and Valyproline were significantly decreased, and metformin treatment could reverse these changes of the above metabolites. Correlation analysis showed that the IL-6 and TNF-α levels were positively correlated with the relative strength of 7-Methylxanthine, N-Arachidonylglycine and other metabolites, but negatively correlated with the Phenazone and Gly-Phe. CCL4 and CXCL1 were positively correlated with Manolide, but negatively correlated with Valyproline. Conclusion:The results of this study showed that metformin improved sepsis induced acute lung injury and regulates the host intestinal metabolites, which might provide a potential and effective treatment for elderly sepsis induced acute lung injury.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Zhishi Xiebai Guizhitang is a classical prescription for the treatment of chest impediment with the method of warming Yang. It is included in the Catalogue of Ancient Classical Prescriptions issued by the National Administration of Traditional Chinese Medicine （First Batch）， with the effect of activating Yang， dissipating mass， moving Qi and resolving phlegm. Its main symptoms include chest fullness and pain， or even chest pain radiating to the back， wheezing， coughing， shortness of breath， and Qi reversal from the hypochondrium. In modern traditional Chinese medicine， Zhishi Xiebai Guizhitang is clinically used in the treatment of cardiovascular system， digestive system， respiratory system and other diseases， among which coronary heart disease， unstable angina pectoris， myocardial infarction， sinus bradycardia and other cardiovascular diseases have particularly significant effects. This paper reviewed the pharmacological studies of Zhishi Xiebai Guizhitang in the past 10 years. The results showed that each single medicine and the whole prescription alleviated the above cardiovascular diseases to a certain extent， with the pharmacological effects of improving intravascular environment， myocardial ischemia， myocardial ischemia-reperfusion injury， and myocardial hypoxia， anti-inflammation， plaque stabilisation， etc.， and the pharmacological mechanism involved the regulation of relevant active substances in vivo as well as related signaling pathways and ion channels， mainly including thromboxane B₂ （TXB₂）， prostacyclin I₂（PGI₂） and phosphatidylinositol 3-kinases/protein kinase B/endothelial nitric oxide synthase （PI3K/Akt/eNOS） signaling pathways， and ATP-sensitive potassium channels. In addition， the relationship between the pharmacological effects of some single medicines and transient receptor potential ankyrin 1 （TRPA1） has been reported that TRPA1 is a key to understanding the mechanism of Zhishi Xiebai Guizhitang in treating cardiovascular diseases， which is worth of further study.

Objective:To investigate the efficacy and safety of Treprostinil in the treatment of children with early decompensation after the Fontan procedure.Methods:A retrospectively analysis was performed on the clinical data of 16 children with early decompensation after the Fontan procedure treated with Treprostinil injection from December 2017 to June 2020 at Fuwai Central China Cardiovascular Hospital.A total of 16 patients were included, including 5 boys (31.2%) and 11 girls (68.8%). The age was (4.6 ±1.2) years, the weight was (16.0±2.1) kg.The changes of central venous pressure (CVP), heart rate (HR), systolic blood pressure (SBP), central venous oxygen saturation (ScvO 2), lactic acid (Lac), oxygenation index and B-type natriuretic peptide (BNP) were recorded at the infusion of Treprostinil and 3 hours, 24 hours, 48 hours and 72 hours after the infusion.The short-term efficacy of Treprostinil was observed[mortality, mechanical ventilation time, and length of intensive care unit (ICU) stay]; paired t-test was used to analyze the above indexes at different time points.The adverse reactions during the administration were also recorded. Results:Of the 16 children, the median mechanical ventilation time was 9 (5, 22) h, and the median ICU stay time was 2 (1, 12)days.After 72 hours of drug administration, CVP, Lac, BNP and HR decreased: CVP decreased from(16±5) mmHg (1 mmHg=0.133 kPa) to (11±2) mmHg ( P<0.001), Lac decreased from(6.8±3.2) mmol/L to (3.2±1.2) mmol/L ( P=0.002), BNP decreased from(980±223) ng/L to (250±120) ng/L( P<0.001), HR decreased from(150±20) times/min to (125±16) times/min( P=0.002); SBP, ScvO 2 and oxygenation index increased: SBP increased from(83±10) mmHg to (98±12) mmHg( P<0.001), ScvO 2 increased from 0.53±0.13 to 0.65±0.11 ( P=0.003), oxygenation index increased from (200±72) mmHg to (298±13) mmHg ( P<0.001), and the differences were statistically significant(all P< 0.05). One case died (6.3%), 2 cases (12.5%) had transient blood pressure drop and 1 case (6.3%) had nausea and vomiting.Besides, no other treatment-related complications were observed. Conclusions:As for children with early decompensation after the Fontan procedure, the intravenous application of Treprostinil can reduce pulmonary artery pressure rapidly, effectively improve circulatory status and oxygenation and ultimately improve the prognosis.
