Nonalcoholic fatty liver disease（NAFLD） is the most common chronic liver disease in the world. Because of its complex pathogenesis， high clinical prevalence and large population， it poses a great threat and challenge to public health in the world. Therefore， active intervention measures are needed. Currently， western medicine is effective in reducing weight， reducing liver fat content， improving glucose-lipid metabolism and insulin resistance. However， for patients with NAFLD-related fibrosis and cirrhosis， there is still a lack of sufficient histological evidence to support its benefits， and randomized controlled trials are still needed to clarify. Lifestyle intervention is an important cornerstone for the treatment of NAFLD， but there are many problems such as poor implementation and low compliance of patients， and the clinical efficacy is not ideal. Traditional Chinese medicine（TCM） has the significant advantages of multiple pathways and multiple targets. Berberine， the active ingredient of TCM， can interfere with the production of NAFLD from multiple pathways， including increasing energy consumption， weight loss， improving glucose-lipid metabolism， improving insulin resistance， anti-inflammatory， anti-oxidation， regulating intestinal flora， restoring bile acid homeostasis， anti-fibrosis and so on， which can play a positive role in the treatment of NAFLD. At the same time， it was found that the combination of BBR with Chinese and western medicines had significant advantages in promoting drug absorption， improving oral bioavailability， increasing the highest biological distribution in the liver， enhancing the overall therapeutic effect of NAFLD， and reducing adverse drug reactions， which could provide reference for clinical medication.

Acute lung injury （ALI） is a common and highly lethal clinical syndrome characterized by acute progressive respiratory failure. Currently， the treatment of ALI primarily involves respiratory support therapy and symptomatic pharmacotherapy， yet there is still a lack of specific and effective pharmacological treatments. Qingwen Baidu decoction is a traditional Chinese medicine formula that has the effects of clearing heat， removing toxin， cooling blood， and purging fire. Its pharmacological effects include anti-inflammatory， antipyretic， antibacterial， antiviral， sedative， and so on. The flavonoids， phenols， terpenes， and other components contained in this formula have strong pharmacological activity， which can regulate the inflammatory response caused and oxidative stress in ALI and maintain the integrity of alveolar-capillary barrier （ACB） by anti-apoptosis， anti-pathogen infection， and anti-pulmonary fibrosis， thereby improving the pathological changes of lung tissue. Among them， flavonoids have been reported more， and their mechanism of action is complex and diverse. For example， quercetin， luteolin， and baicalin act on multiple important targets， such as signal transducer and activator of transcription 3 （STAT3）， mitogen-activated protein kinase 3 （MAPK3）， etc. and participate in the regulation of Toll-like receptor 4 （TLR4）/myeloid differentiation primary response 88 （MyD88）/nuclear factor kappa B （NF-κB）， nuclear factor erythroid 2-related factor 2（Nrf2）/Kelch-like ECH-associated protein 1 （Keap1）， and silent information regulator 1 （SIRT1）/forkhead box protein O1 （FoxO1） signaling pathways， thereby intervening in pathological events such as inflammation， oxidative stress， cell apoptosis， and fibrosis. This paper aims to review the research progress on Qingwen Baidu decoction and its active ingredients in the prevention and treatment of lung injury in the expectation of providing reference for its subsequent pharmacological mechanism research and theoretical support for its clinical application and drug development in the treatment of ALI.

Objective: To investigate the distribution characteristics of Kidd blood group antigens, phenotypes and genotypes in Xinjiang and their influence on the risk of coronary heart disease. Methods: Samples from 7 981 patients treated at People's Hospital of Xinjiang Uygur Autonomous Region from August 1, 2023 to May 31, 2024 were collected for Jk(a-b-) phenotype screening via urea hemolysis test, followed by the third-generation sequencing (TGS). Kidd blood group Jk and Jk antigens in 1 081 patients with coronary heart disease and 1 021 healthy people were detected, and their phenotype frequency distribution was analyzed and corresponding gene frequencies were calculated. Correlation analysis and logistic regression were used to evaluate the influence of Kidd blood group antigen expression on coronary heart disease risk. Results: Two Jk(a-b-) phenotype samples were detected, both resulting from novel gene mutation combinations. Comparative analysis of two groups revealed a higher proportion of the Jk(a-b+) phenotype in the case group (22.5%, 243/1 081) than in the control group (18.5%, 189/1 021). Moreover, Kidd blood group phenotype distribution varied significantly across all ethnic groups in the case group (P<0.05). In the control group, the Hui ethnic group exhibited the highest JK JK genotype frequency 64.15% (34/53). In the case group, the highest JK allele frequency was observed in Mongol ethnic group 56.31% (125/222), and the lowest in Han patients 45.71% (341/746). The expression of Jk antigen was negatively correlated with coronary heart disease (P<0.05). Conclusion: The distribution of Kidd blood group system varied across ethnic groups in Xinjiang. The expression of Jk antigen may have protective effect on coronary heart disease, which provides a basis for future clinical blood transfusion treatment and the mechanism study of the correlation between Kidd blood group and coronary heart disease.

OBJECTIVE To explore the effects of CD20 coding gene （MS4A1） polymorphism on the blood concentration and efficacy of rituximab in patients with non-Hodgkin’s lymphoma. METHODS A prospective observational study was conducted on 160 newly diagnosed non-Hodgkin’s lymphoma patients who received the R-CHOP regimen at the Sun Yat Sen University Cancer Center from January 2016 to December 2020， with a minimum follow-up period of approximately 5 years. The blood concentration of rituximab was detected by enzyme-linked immunosorbent assay. MS4A1 tagSNPs were selected by Haploview4.2 software， including rs1051461， rs17155034， rs4939364， and rs10501385. The genotype of MS4A1 was detected by Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. Univariate linear regression analysis was employed to examine the correlation between various factors（demographic， clinical， and genotypic variables） in patients and the steady-state trough concentration of rituximab during the first course of treatment， followed by multivariate linear regression analysis. Kaplan-Meier curves were drawn to evaluate progression-free survival （PFS） and overall survival （OS）. Using MS4A1 genotype and tumor stage as independent variables， Cox regression model was employed to evaluate the factors influencing patient prognosis. RESULTS The blood concentration of rituximab in MS4A1 rs10501385 CC carriers was 15.20 μg/mL，which was significantly lower than 21.95 μg/mL in AA+AC carriers （P＜0.05）. The multivariate linear regression model incorporating tumor stage and MS4A1 rs10501385 polymorphism explained 7.3% of the interindividual variability in rituximab concentrations. Compared with MS4A1 rs1051461 CC carriers， CT+TT carriers had significantly prolonged PFS and OS （P＜0.05）. The Cox proportional hazards regression model showed that the MS4A1 rs1051461 CC genotype （HR＝4.406， 95%CI：1.743-11.137， P＜0.05） and tumor Ⅲ&Ⅳ （HR＝3.233， 95%CI： 1.413-7.399， P＜0.05） were independent risk factors for PFS. CONCLUSIONS The tumor staging and MS4A1 rs10501385 polymorphism are key influencing factors for blood concentration of rituximab， and MS4A1 rs1051461 polymorphism significantly affects PFS in non-Hodgkin’s lymphoma patients.

To address the current issues of data imbalance and scarcity in photoplethysmography (PPG) data for type 2 diabetes mellitus (T2DM) prediction, this study proposes an improved conditional Wasserstein generative adversarial network with gradient penalty (CWGAN-GP). The algorithm integrated gated recurrent unit (GRU) networks and self-attention mechanisms to construct a generator, aiming to produce high-quality PPG signals. Various data augmentation methods, including the improved CWGAN-GP, were employed to expand the PPG dataset, and multiple classifiers were applied for T2DM prediction analysis. Experimental results showed that the model trained on data generated by the improved CWGAN-GP achieved the optimal prediction performance. The highest accuracy reached 0.895 0, and compared with other data enhancement methods, this approach exhibited significant advantages in terms of precision and F1-score. The generated data notably enhances the accuracy and generalization ability of T2DM prediction models, providing a more reliable technical basis for non-invasive early T2DM screening based on PPG signals.

Objective To compare the analgesic effect, duration and incidence of adverse reactions of liposome bupivacaine (LB) and bupivacaine hydrochloride after intercostal nerve block in single-port thoracoscopic lung surgery. Methods In Department of Thoracic Surgery of the First Affiliated Hospital of Xinxiang Medical University between September 2023 and March 2024, 228 patients who needed to undergo thoracoscopic lung surgery were selected and divided into two groups by random number table method: a group B with bupivacaine hydrochloride (n=118), and a group LB with LB (n=110). Intraoperative intercostal nerve block was performed under endoscopy, and the time of first use of analgesic drugs after surgery, cumulative use of opioids 72 h after surgery, incidence of postoperative nausea and vomiting, length of stay and other indicators were evaluated and recorded. Results Visual analogue scale (VAS) scores at 4 h, 8 h, 12 h, 24 h, 48 h and 72 h in the LB group were significantly lower than those in the group B (P<0.05). The total number of activities within 48 h after surgery in the group B was significantly lower than that in the LB group (P<0.05), and the postoperative hospitalization stay in the LB group was shorter than that in the group B, but the difference was not statistically significant. There was no statistical difference between the two groups in postoperative adverse reactions. Conclusion Intercostal nerve block with LB during single-port thoracoscopic lung surgery can significantly reduce postoperative pain, improve quality of life, and promote recovery of the patients. It is worthy of clinical application.

OBJECTIVE To study the inhibitory effect and mechanism of curcumin and its derivatives A and B on TGF-β induced LX-2 cell fibrosis. METHODS Established the liver fibrosis model of LX-2 cells induced by TGF-β(10 ng·mL−1).The effects on cell proliferation were detected by CCK-8. The effects on cell apoptosis was detected by flow cytometry. The effects on fibrosis related factors(Collagen I, Collagen Ⅳ, Fibronectin, Vimentin, α-SMA, PDGFRβ, TGFβR1, TGFβR2, MMP2, MMP9, TIMP1 and TIMP2) protein expression and gene transcription levels were detected by Western blotting and q-PCR. RESULTS The curcumin and its derivative A and B had the inhibition effects on normal LX-2 cells, and the IC25 values were 15.7, 2.6, 10.2 μmol·L−1, respectively. Compared to the model group, the curcumin(15.7 μmol·L−1) and its derivative A(2.6 μmol·L−1) and B(10.2 μmol·L−1) had the significant inhibition effects on cell proliferation of the TGF-β induced LX-2 cells(P<0.05). The cell apoptosis rate of curcumin derivative B group was higher than the model group(P<0.05). Collagen I, Fibronectin, Vimentin, α-SMA, TGFβR1 and TIMP-1 protein expression levels in curcumin group were lower, while the protein expression level of MMP-9 was higher(P<0.05). The protein expression levels of Collagen I, Collagen IV, Fibronectin, Vimentin, α-SMA, TIMP-1 and TIMP-2 in curcumin derivative A group were lower, while the protein expression level of MMP-2 was higher(P<0.05). The protein expression levels of Collagen I, Collagen IV, Fibronectin, Vimentin, α-SMA, PDGFRβ, TGFβR1, TGFβR2, TIMP-1 and TIMP-2 in curcumin derivative B group were lower, while the protein expression level of MMP-2 was higher(P<0.05). The gene transcription levels of Collagen I, Fibronectin, α-SMA and TIMP-1 in curcumin group were lower(P<0.05). The gene transcription levels of Collagen I, Fibronectin and α-SMA in curcumin derivative A and B groups were lower(P<0.05). CONCLUSION Curcumin and its derivatives A and B inhibit the abnormal activation and proliferation of TGF-β-induced LX-2 cells, inhibit the excessive secretion and accumulation of its extracellular matrix components, and promote its degradation, thus playing an anti-fibrotic effect in vitro, especially the curcumin derivative B.

Objective To construct and identify a patient-derived organoid model,and to investigate the sensitivity of chemotherapy drugs using this model.Methods Pancreatic cancer cells were obtained from the surgical specimens of two female patients with a confirmed diagnosis of pancreatic cancer after tumor tissue digestion,and then the cells were inoculated into a culture dish using matrigel for three-dimensional culture.Paraffin sections were prepared for HE staining and immunohistochemical staining and were compared with the parent tumor tissue to determine whether the histopathological features of the tumor in vivo were preserved.The pancreatic cancer organoids were treated with seven chemotherapy drugs at different concentrations;Cell Titer-Glo?3D reagent was used to measure cell viability,and the results of drug sensitivity were analyzed.Results Two patient-derived pancreatic cancer organoids were successfully constructed,and HE staining and immunohistochemical staining showed that the pancreatic cancer organoids had consistent histopathological features with the tumors of the corresponding patient.Both pancreatic cancer organoids were more sensitive to gemcitabine monotherapy and the combination of oxaliplatin+SN38+fluorouracil,and patient 1 was more sensitive than patient 2.There were individual differences in the response to drugs between the organoids from different patients.Conclusion The pancreatic cancer organoid model successfully constructed in this study can reflect the histological classification of parent pancreatic tumors and can be used for in vitro chemotherapy drug sensitivity test,which is expected to provide a reference for clinical medication.

OBJECTIVE To construct a risk prediction model for non-compliance with inhaled medication in patients with chronic obstructive pulmonary disease （COPD）. METHODS A retrospective analysis was conducted on 365 COPD patients admitted to the cough and wheeze pharmaceutical care clinic of the First Hospital of Qinhuangdao from October 2021 to October 2023. The patients admitted from October 2021 to June 2023 were selected as the model group （n＝303）， and the patients admitted from July to October 2023 were selected as the validation group （n＝62）. The model group was divided into compliance subgroup （n＝126） and non-compliance subgroup （n＝177）. Univariate analysis combined with multivariate Logistic regression analysis were used to analyze the risk factors for non-compliance with inhaled formulations in patients； the risk prediction model was established through regression analysis， and the accuracy of the model prediction was evaluated based on the validation group of patients. RESULTS Multivariate Logistic regression analysis showed that simultaneous use of 2 inhaled formulations （OR＝3.730， 95%CI 1.996-6.971， P＜0.001）， the number of acute exacerbations within one year ≥2 （OR＝2.509， 95%CI 1.509-4.173， P＜0.001）， smoking （OR＝2.167， 95%CI 1.309-3.588， P＝0.003）， complicated with anxiety/depression （OR＝2.112， 95%CI 1.257-3.499， P＝0.004） and mMRC grading≥2 levels （OR＝1.701， 95%CI 1.014-2.853， P＝0.044） were risk factors for non-compliance with inhaled preparations. Based on this， a risk prediction model was established and the ROC curve was drawn. The areas under the curve of the model group and validation group were 0.836 and 0.928， and the overall accuracy of the model’s prediction was 88.71%. CONCLUSIONS The predictive model based on the simultaneous use of 2 inhaled formulations， the number of acute exacerbations within one year ≥2， smoking， complicated with anxiety/depression， mMRC grading ≥2 levels has certain predictive value for the risk of non-compliance with inhaled formulations for COPD patients.
