OBJECTIVE To evaluate the cost-effectiveness of sintilimab combined with chemotherapy than single-use chemotherapy in the first-line treatment of advanced， recurrent or metastatic esophageal squamous cell carcinoma （ESCC） from the perspective of health system of our country， and provide reference for rational use of drug in clinic. METHODS Based on ORIENT-15 study data， TreeAge Pro 2011 software was used to establish a three-state Markov model of non-progressive survival （PFS）， disease progression and death for cost-utility analysis. The model period was 3 weeks， the research time limit was 10 years， and the discount rate was 5%. The main outputs of the model were total cost， quality-adjusted life year （QALY） and incremental cost-effectiveness ratio （ICER）. The 1-3 times of China’s GDP per capita in 2021 was taken as the threshold of willing- ness to pay （WTP）. The uncertainty of the parameters was analyzed by single factor sensitivity analysis and probability sensitivity analysis， and the cost-effectiveness of the two schemes was discussed under three situations： different discount rates， comparison with other similar treatment schemes and charitable drug donation schemes. RESULTS The results of basic analysis showed that compared with chemotherapy plan alone， the ICER of sintilimab combined with chemotherapy was 64 208.75 yuan/QALY， which was less than WTP threshold. The results of single factor sensitivity analysis show that PFS state utility value， cycle cost of sintilimab and discount rate had relatively great influence on the results. Probability sensitivity analysis showed that when WTP≥120 000 yuan， the economic probability of sintilimab combined with chemotherapy plan was 100%. The results of situational analysis showed that sintilimab combined chemotherapy was more cost- effective than single-use chemotherapy. CONCLUSIONS Sintilimab combined with chemotherapy is more cost-effective than single-use chemotherapy in the first-line treatment of advanced， recurrent or metastatic ESCC.

By organizing and studying on the original works of LI Wenrong， this paper aimed to explore his theories and methods for treating liver diseases. LI Wenrong believes that the liver is easily prone to physiological disturbances， difficult to pacify， and can be compared to a “chariot” that moves horizontally and vertically， acting as a “general” for both civil and military affairs. Pathologically， liver diseases tend to spread to other organs， resulting in ever-changing pathological changes， often affecting emotional health. In terms of therapeutic methods， LI Wenrong proposes ten methods including draining fire to calm the liver， nourishing water to moisten wood， clearing metal to calm the liver， calming gallbladder and harmonizing liver， subduing yang with shell-drug， treating liver diseases by supplementing spleen， soothing the liver with sweetness， astringing the liver with sourness， relieving the liver with spiciness， and draining the liver with excess-fire. These methods have great guidance and reference value for contemporary clinical practice in traditional Chinese medicine.

ObjectiveTo investigate the mechanism of Biejiajian Wan in the intervention of primary liver cancer based on long non-coding RNA SNHG5 （lncRNA SNHG5）/micro RNA-26a-5p （miRNA-26a-5p）/glycogen synthase kinase-3β （GSK-3β） signal axis. MethodDouble luciferase reporting assay was used to verify the targeted interaction between lncRNA SNHG5 and miRNA-26a-5p， miRNA-26a-5p， and GSK-3β in HepG2 cells. Nude-mouse transplanted tumor model of human HepG2 were established and randomly divided into model group， Biejiajian Wan low-dose group （0.5 g·kg^-1）， medium-dose group （1.0 g·kg^-1）， and high-dose group （2.0 g·kg^-1）， and sorafenib group （100 mg·kg^-1）， with 10 mice in each group. The mice were given intragastric administration of normal saline or drug for 28 days， and the tumor volume was measured at different time. Hematoxylin-eosin （HE） staining was used to observe the histological changes of tumors. The nucleic acid levels of lncRNA SNHG5， miRNA-26a-5p， GSK-3β， and β-catenin mPNA in tumor tissue were detected by real-time quantitative polymerase chain reaction （Real-time PCR）. The protein expression levels of GSK-3β and β-catenin in tumor tissue were detected by western blot. ResultCompared with the SNHG5-WT （wild type） + miRNA NC （negative control） group， the relative luciferase activities of the SNHG5-WT + miRNA-26a-5p mimic group were decreased （P<0.05）. Compared with the GSK-3β-WT + miRNA NC group， the relative luciferase activity of the GSK-3β-WT + miRNA-26a-5p mimic group was decreased （P<0.05）. Compared with the model group， the tumor volume of Biejiajian Wan low-dose， medium-dose， and high-dose groups was significantly decreased （P<0.05， P<0.01）. Compared with the model group， the cells in the tumor tissue of nude mice in each dose group of Biejiajian Wan were sparsely arranged with necrocytosis， which showed concentration-dependent changes. Compared with the model group， the expression levels of lncRNA SNHG5， GSK-3β， and β-catenin were decreased （P<0.05， P<0.01）， while the expression of miRNA-26a-5p was increased in each dose group of Biejiajian Wan （P<0.05， P<0.01）. Compared with the model group， the protein expression levels of GSK-3β and β-catenin were decreased in each dose group of Biejiajian Wan （P<0.05， P<0.01）. ConclusionBiejiajian Wan may affect the necrosis of liver cancer cells through lncRNA SNHG5/miRNA-26a-5p/GSK-3β signal axis and thus play an anti-tumor role. This research will provide more theoretical basis for the clinical application of Biejiajian Wan.

The amount of data generated by the human experience in medical cases of classic formulas is large and the research value is high， but how to extract valuable information from these massive data is an important problem of researches on classical formulas. It is concluded that there are many problems in the current study of human experience in classical formulas， such as large amount of data， uneven quality， weak extrapolation and clinical application， which seriously affected the evidence strength of human experience in classical formulas and the contribution to experience accumulation and theoretical support. Therefore， from the structural perspective of the research questions， this paper proposed the research ideas of human experience in medical cases of classic formulas： firstly， according to the characteristics of traditional Chinese medicine （TCM） cases， based on the PICO model， which refers parti-cipants （P）， intervention （I）， comparisons （C）， and outcomes （O）， a TCM medical record evaluation tool in line with the evidence-based concept was constructed to evaluate the quality of medical cases； secondly， constructing a standardized database of human experience in classical formulas and using data mining algorithms to explore the deep relationship hidden in human experience； finally， the clinical value evaluation is carried out to verify the effectiveness of the diagnosis and treatment rules of classical formulas to achieve clinical transformation.
