This paper explores the therapeutic approach for glaucoma based on the concept of "jueyin （厥阴） as the closing phase" from the perspectives of time and space. In traditional Chinese medicine， jueyin governs inward， converging aspect of qi， representing the crucial turning point between the end of yin and the emergence of yang， as well as the transformation between yin and yang. When the closing and descending function of jueyin operates smoothly， it promotes the inward convergence and smooth descent of qi， enabling the internal retention of blood， spirit， and emotions， which nourishes the internal organs and moistens the meridian-sinews. Conversely， dysfunction of this "closing" mechanism results in a disturbance of yin and yang， a mixture of cold and heat， and disharmony of qi and blood. It is proposed that "failure of jueyin to properly close and descend" is a core pathomechanism of glaucoma. From the perspective of spatiotemporal theory， clinical treatment should focus on "regulating the closing function of jueyin and harmonizing yin and yang". The modified Wumei Pill （乌梅丸） is recommended to adjust the ascending-descending and entering-exiting dynamics of jueyin qi transformation， thereby restoring its free flow， achieving yin and yang balance， and ensuring nourishment to the ocular system.

Autoimmune hepatitis （AIH） is a chronic inflammatory liver disease. The pathogenesis of AIH remains unclear， but it is mainly autoimmune injury caused by the breakdown of autoimmune tolerance due to the abnormal activation of the immune system， while the specific molecular mechanism remains unknown. Recent studies have shown that abnormal amino acid metabolism plays an important role in the development and progression of AIH. This article reviews the research advances in amino acid metabolic reprogramming in AIH， in order to provide a theoretical basis for amino acid metabolism as a new target for the clinical diagnosis and treatment of AIH.

OBJECTIVE From the perspective of China’s healthcare system， to evaluate the cost-effectiveness of tislelizumab in patients with locally advanced or metastatic squamous or non-squamous non-small cell lung cancer （NSCLC） whose disease progresses or is intolerable after receiving platinum-containing dual chemotherapy in the past. METHODS Rationale-303 research data were used to construct a partitioned survival model. The model period was set to be 21 days and simulated to 120 months. Using quality-adjusted life year （QALY） as a health output index， the incremental cost-effectiveness ratio （ICER） was calculated by discounting cost and health output with a discount rate of 5%. Single-factor sensitivity analysis and probability sensitivity analysis were performed to verify the robustness of the basic analysis results. RESULTS Cost-utility analysis results showed that the ICER of tislelizumab group was 65 653.52 yuan/QALY， compared with docetaxel group. This means that the regimen of tislelizumab was more cost-effective than the docetaxel regimen when the willingness-to-pay threshold （WTP） was 3 times China’s gross domestic product （GDP） per capita in 2023 （268 200 yuan/QALY）. The results of single-factor sensitivity analysis showed that the three parameters that had a greater impact on ICER were the prices of tislelizumab， docetaxel and pemetrexed. The results of the probabilistic sensitivity analysis showed that the probabilities of the above two treatment regimens being cost-effective were both 50% when the WTP threshold was approximately 65 000 yuan/QALY. The probability of tislelizumab regimen being cost- effective was 100% when the WTP threshold was ≥134 000 yuan/QALY. CONCLUSIONS From the perspective of China’s healthcare system， when taking 3 times China’s GDP per capita in 2023 as the WTP threshold， tislelizumab is cost-effective for patients with locally advanced or metastatic squamous or non-squamous NSCLC after receiving platinum-containing dual chemotherapy in the past， compared with docetaxel.

Bladder cancer （BCa） is the most common malignant tumor of the urinary system， and its incidence is increasing year by year. At present， for all patients with resectable non-metastatic muscle-invasive BCa， radical cystectomy + bilateral pelvic lymph node dissection is strongly recommended， but they still face the risk of recurrence， metastasis and death. In recent years， the proportion of patients with advanced and metastatic BCa is increasing among patients with newly diagnosed BCa. Although current treatment models are diverse， they often struggle to achieve significant efficacy due to their low effectiveness and adverse effects， resulting in low survival rates for patients with advanced and metastatic BCa. Therefore， the treatment of BCa still faces great challenges， and there is an urgent need to discover an effective new antitumor drug. With the improvement of medical standards， traditional Chinese medicine has shown great advantages in the treatment of BCa. Traditional Chinese medicine is mild and easy to accept， and can inhibit tumor progression through a multi-pathway， multi-way and multi-target manner， so as to exert its anticancer effect. Taraxaci Herba is a medicinal and food homologous plant， which has many biological activities， such as antibacterial， anti-inflammatory， anti-oxidation， anti-tumor， protecting liver and gallbladder， reducing blood sugar and enhancing immunity， and it has shown a clear anticancer effect in breast cancer， liver cancer， gastric cancer， tongue cancer and lung cancer. By reviewing previous studies worldwide， this article summarizes the mechanism of Taraxaci Herba extract in inducing autophagy and apoptosis， inhibiting cell migration and invasion， regulating cell cycle and proliferation， regulating cell metabolism， inhibiting tumor angiogenesis， combining the effects of chemotherapeutic drugs， and regulating the transduction of related signal pathways. On this basis， this study systematically elaborates on the potential mechanism of Taraxaci Herba against BCa， in order to provide a theoretical basis for the research and treatment of BCa.

ObjectiveTo evaluate the efficacy and safety of Lianhua Qingke tablets in the treatment of acute bronchitis in children with the syndrome of phlegm-heat obstructing lung. MethodA randomized， open， parallel controlled， and multi-center clinical study was conduted. Children with acute bronchitis （syndrome of phlegm-heat obstructing lung） were randomly assigned to an observation group and a control group. The control group received routine basic treatment， and the observation group was treated with Lianhua Qingke Tablets on the basis of routine basic treatment. After 7 days of treatment， the clinical efficacy， TCM efficacy， time to symptom disappearance， time to cough disappearance， and clinical safety were compared between the two groups. ResultA total of 248 children were included （124 in the observation group and 124 in the control group）. After 7 days of treatment， the total response rate in terms of clinical efficacy in the observation group was 96.8% （120/124）， which was higher than that （90.3%， 112/124） in the control group （Z=-5.034， P<0.01）. The total response rate in terms of TCM syndrome in the observation group was 97.6% （121/124）， which was higher than that （93.5%， 116/124） in the control group （χ²=-5.326， P<0.01）. The scores of physical signs and TCM symptoms in the observation group were lower than those in the control group at the time of taking medicine for 3 days and 7 days （P<0.01）. The time to symptom disappearance and the time to cough disappearance in the observation group were shorter than those in the control group （P<0.01）. Drug-related adverse reactions occurred in neither group. ConclusionLianhua Qingke tablets demonstrate a definite effect on acute bronchitis in children with the syndrome of phlegm-heat blocking lung. The tablets can significantly shorten the course of disease and relieve cough and TCM symptoms， with high safety， which is worthy of clinical application and promotion.

ObjectiveThis study aims to explore the potential mechanism of Danggui Niantongtang in treating knee osteoarthritis （KOA） by regulating the intestinal flora through 16S rDNA analysis. MethodThirty-six C57BL/6J mice were subjected to anterior cruciate ligament transection （ACLT） to establish a KOA model and were randomly divided into the sham surgery group， model group， low-dose Danggui Niantongtang group （0.819 g·kg^-1）， medium-dose Danggui Niantongtang group （1.638 g·kg^-1）， high-dose Danggui Niantongtang group （3.276 g·kg^-1）， and Meloxicam group （0.975 mg·kg^-1）， with 6 mice in each group. Except for the treatment groups， the sham surgery group and model group were given normal saline by gavage. After 4 weeks of continuous intervention， feces and intact knee joints of the mice were collected. Hematoxylin-eosin （HE） staining and Safranin O-Fast Green staining were performed to observe the pathological changes in knee joint tissue morphology. The 16S rDNA sequencing was used to analyze changes in the abundance and diversity of intestinal microorganisms before and after treatment， along with corresponding functional predictions. ResultHigh-dose Danggui Niantongtang and Meloxicam significantly relieved pain symptoms in KOA mice， improved the disorder of joint structure， maintained the integrity of knee articular cartilage， increased the expression of type Ⅱ collagen alpha 1 （Col2a1） in articular cartilage， and decreased the expression of matrix metalloproteinase-13 （MMP-13）. The results of 16S rDNA sequencing showed that high-dose Danggui Niantongtang could adjust the abundance and structure of intestinal microbial species. Compared with the sham surgery group， the abundance of Proteobacteria， Actinobacteria， Ruminococcus， and Bacteroides was significantly increased in the model group （P<0.05）， while in the Danggui Niantongtang group， the abundance of these four flora was significantly reduced compared with the model group. Compared with the sham surgery group， the abundance of Verrucomicrobia， Oscillospira， and Akkermansia was significantly decreased in the model group （P<0.05）， while in the Danggui Niantongtang groups， the abundance of these three flora was significantly increased compared with the model group （P<0.05）. Functional pathway prediction of differential genera revealed that species differences among groups mainly involved metabolic pathways with high abundance associated with biosynthesis and precursors， as well as energy production， including amino acid biosynthesis， nucleotide and nucleoside biosynthesis， cofactors， prosthetic groups， electron carriers， and vitamin biosynthesis. ConclusionDanggui Niantongtang can effectively protect articular cartilage and delay the progression of KOA， possibly by regulating the structure of the intestinal flora， promoting probiotics， and inhibiting the growth of harmful pathogenic bacteria.

Objective:To construct pancreatic cancer cell lines expressing luciferase and mesothelin (MSLN), and evaluate the feasibility of using them as target cells in analyzing the cytotoxicity activity of immune cells.Methods:Lentiviral vectors expressing luciferase and MSLN genes were constructed, and pancreatic cancer cell lines were infected after lentivirus packaging. Single-cell clones were obtained by limited dilution following antibiotic screening, and the stable expression of the target genes were verified. These cells were used as target cells to detect the cytotoxicity of immune cells by real-time cell analysis (RTCA) and luciferase activity. Besides, these luciferase-expressing cells were transplanted into B-NDG mice to establish the animal models of pancreatic cancer, and in vivo optical imaging technology was used to detect the expression of luciferase and monitor the tumor growth in mice. The cytotoxicity of chimeric antigen receptor T (CAR-T) cells was verified in these animal models. Results:Three pancreatic cancer cell lines, panc-1-luc, panc-1-luc-MSLN and capan-2-luc, that could stably express luciferase and MSLN genes were successfully constructed. The expression of the reporter gene in these cells were high, and positively correlated with the number of cells. There were 95.6% of panc-1-luc-MSLN cells expressing MSLN. MSLN-CAR-T cells had specific killing effect on MSLN-positive panc-1-luc-MSLN cells and capan-2-luc cells, with the minimum killing rates of (70.00±18.19)% and (57.00±5.29)%, respectively. But they had no cytotoxicity to MSLN-negative panc-1-luc cells. RTCA results showed that MSLN-CAR-T cells were able to lyse all three pancreatic cancer cell lines, and the minimum killing rates were (56.33±7.64)%, (93.00±2.65)% and (26.33±28.15)%, respectively. The killing of target cells by NK-92MI cells was not depended on MSLN expression. The cytotoxicity in the mice models of pancreatic cancer was consistent with the results in vitro. The in vivo and in vitro test results suggested that the expression of luciferase by target cells could reflect the cytotoxicity of immune cells. Conclusions:This study establishes three pancreatic cancer cell lines stably expressing luciferase, which can be used to evaluate the cytotoxicity of immunotherapy products targeting tumor cells in vitro and in vivo.
