ObjectiveTo observe the clinical efficacy and safety of Guben Quyu Jiedu prescription in treating nocturnal hypoxemia of chronic obstructive pulmonary disease （COPD） combined with Obstructive sleep apnea hypopnea syndrome （ OSAHS ） （deficiency of lung， spleen and kidney with blood stasis and toxicity）. MethodsThe paper used a forward-looking， random double-blind， placebo-controlled design method to select 96 patients with COPD combined with OSAHS， and their traditional Chinese medicines （TCM） syndrome differentiation was deficiency of lung， spleen and kidney with blood stasis and toxicity. These patients were randomly divided into the observation group and the control group， with 48 cases in each group. Based on conventional Western medicine treatment， the observation group was treated with Guben Quyu Jiedu prescription and the control group was treated with traditional Chinese medicine placebo. Both courses of treatment were 90 days. Then the paper compared the changes in minimum pulse oxygen saturation （SpO₂） during the night， apnea index （AHI）， OSAHS efficacy evaluation， TCM syndrome efficacy evaluation， and TCM symptom score before and after treatment between the two groups. ResultsThere were 5 withdrawals in the observation group and 8 withdrawals in the control group， so 43 cases in the observation group and 40 cases in the control group completed the trial. Compared with the condition before treatment， the minimum SpO₂ during the night and AHI in the observation group were significantly improved at night （P<0.01） and were better than those in the control group （P<0.01）. OSAHS efficacy in the observation group was better than in the control group （χ²=7.085， P<0.05）. In terms of TCM syndrome efficacy， the total effective rate was 81.40% （35/43） in the observation group， significantly higher than that in the control group， which was 15.00% （6/40） （χ²=36.78， P<0.01）. The TCM symptom scores of the two groups were improved compared with the condition before treatment， and the effect of the two groups was similar in the four main symptoms of snoring， choking， lethargy， and cough. However， the observation group was better than the control group in 10 details such as dizziness， headache， chest tightness， chest pain， wheezing， dry mouth， and thirst （P<0.05）. ConclusionUsing Guben Quyu Jiedu prescription combined with conventional Western medicine can treat COPD combined with OSAHS hypoxemia at night （deficiency of lung， spleen and kidney with blood stasis and toxicity）. In this way， the minimum pulse oxygen saturation （SpO₂） of patients， the level of disease control， and the quality of life of patients can be improved， and the clinical symptoms can be relieved.

Objective : To investigate the brain microvascular tissue block culture method for extracting primary rat brain microvascular endothelial cells and identify its effect. Methods : Brain tissue from 4-week-old Sprague Dawley rats was screened, pre-digested and solidified to obtain brain microvascular segments. These segments were subsequently placed in a CO2incubator for primary culture. The target cells were identified by cell morphology and immunocytochemical staining for factor Ⅷ-related antigen. Results : After a 48-hour culture periodin vitro, the short spindle cells crawled out from around the brain microvascular segments. After 72 hours, island-like cell culsters formed. After 96 hours the clusters fused and the cells formed a typical monolayer, cobble stone-like, and mosaic arrangement. Factor Ⅷ-related antigen immunocytochemical staining showed that the cytoplasm of the cells appeared brown-red, indicating positive expression; DAB stained the nucleus, showing blue-dark. Conclusion The brain microvascular tissue block culture method can isolate and culture primary rat brain microvascular endothelial cells.

Hepatitis B cirrhosis is the most significant component of liver cirrhosis in China， and there is a significant increase in the mortality rate of patients after progression from hepatitis to liver cirrhosis. A large number of studies have shown that gut microbiota may influence the progression of hepatitis B cirrhosis， including the impact on the regulation of inflammatory response and intestinal immunity， the inhibition of HBV， and the production of ammonia-like substances. This article reviews the research advances in the changes in gut microbiota in hepatitis B cirrhosis patients and explores new ideas for the treatment of hepatitis B cirrhosis by intervening in gut microbiota.

Lignans are a powerful weapon for plants to resist stresses and have diverse bioactive functions to protect human health. Elucidating the mechanisms of stereoselective biosynthesis and response to stresses of lignans is important for the guidance of plant improvement. Here, we identified the complete pathway to stereoselectively synthesize antiviral (-)-lariciresinol glucosides in Isatis indigotica roots, which consists of three-step sequential stereoselective enzymes DIR1/2, PLR, and UGT71B2. DIR1 was further identified as the key gene in respoJanuary 2024nse to stresses and was able to trigger stress defenses by mediating the elevation in lignan content. Mechanistically, the phytohormone-responsive ERF transcription factor LTF1 colocalized with DIR1 in the cell periphery of the vascular regions in mature roots and helped resist biotic and abiotic stresses by directly regulating the expression of DIR1. These systematic results suggest that DIR1 as the first common step of the lignan pathway cooperates with PLR and UGT71B2 to stereoselectively synthesize (-)-lariciresinol derived antiviral lignans in I. indigotica roots and is also a part of the LTF1-mediated regulatory network to resist stresses. In conclusion, the LTF1-DIR1 module is an ideal engineering target to improve plant Defenses while increasing the content of valuable lignans in plants.

AIM: To predict the core targets and related signaling pathways of Yi-xin-yin oral liquid for the treatment of arrhythmia, heart failure and myocarditis based on UHPLC-Q-TOF/MS, network pharmacology, molecular docking methods, cell experiments, according to the“homotherapy for heteropathy”theory in traditional Chinese medicine. METHODS: UHPLC-Q-TOF / MS was used to analyze and identify the chemical composition of Yi-xin-yin oral liquid Extract and the blood-absorbing components of rats oral administrated with Yi-xin-yin oral liquid extract, which compounds were applied in the databases searching for the potential targets (TCMSP, SwissTargetPrediction) and disease targets (OMIM, Genecard). Venn diagram was used for target intersection, and the subsequent protein-protein interaction network obtained core targets by STRING11.5 database, and then construct a "disease-component-target" network by cytoscape3.9.0. Finally, DAVID database was used to analysis GO function and KEGG enrichment analysis of core targets, and molecular docking validation was performed using Autodock vina software. And, validated with H9c2 cells for potential active ingredients and targets. RESULTS: A total of 156 compounds were identified from Yi - xin-yin Oral Liquid extract; 34 compounds were identified from rat serum, including 6-gin-gerol, isoliquiritigenin, glycyrrhizic acid and other compounds, and 139 intersecting targets were obtained. The KEGG pathway enrichment analysis mainly involved the TNF signaling pathway, IL-17 signaling pathway, MAPK signaling pathway, PI3K-Akt signaling pathway and so on. The TNF and IL-6 targets were selected for molecular docking with the main compounds, and the docking results were good (less than -5 kcal/mol). In vitro cellular experiments have shown that Yi-xin-yin oral liquid can exert therapeutic effects by regulating TNF and IL-6. CONCLUSION: The main potential active ingredients of Yi-xin-yin oral liquid may be isoliquiritigenin, glycyrrhetinic acid, calycosin-7-glucoside, salvianolic acid B, and 6-gingerol, which mainly act on TNF, IL-6 and other targets to regulate specific signaling pathways and exert therapeutic effects.

Background::Previous studies have reported associations of specific maternal and paternal lifestyle factors with offspring’s cognitive development during early childhood. This study aimed to investigate the prospective associations between overall parental lifestyle and offspring’s cognitive performance during adolescence and young adulthood in China.Methods::We included 2531 adolescents aged 10-15 years at baseline in 2010 from the China Family Panel Studies. A healthy parental lifestyle score (ranged 0-5) was constructed based on the following five modifiable lifestyle factors: Smoking, drinking, exercise, sleep, and diet. Generalized estimating equation models were used to examine the association between baseline parental healthy lifestyle scores and offspring’s fluid and crystallized intelligence in subsequent years (2012, 2014, 2016, and 2018).Results::Offspring in the top tertile of parental healthy lifestyle scores performed better in overall fluid intelligence (multivariable-adjusted β = 0.53, 95% confidence interval [CI]: 0.29-0.77) and overall crystallized intelligence (multivariable-adjusted β = 0.35, 95% CI: 0.16-0.54) than those in the bottom tertile of parental healthy lifestyle scores. The results were similar after further adjustment for the offspring’s healthy lifestyle scores and persisted across the subgroups of parental socioeconomic status. Additionally, maternal and paternal healthy lifestyle scores were independently associated with better offspring’s cognitive performance, with significant contribution observed for paternal never-smoking, weekly exercise, and diversified diet. When both parents and offspring adhered to a healthier lifestyle, we observed the highest level of the offspring’s overall crystallized intelligence. Conclusions::Our study indicates that parental adherence to a healthier lifestyle is associated with significantly better offspring’s cognitive performance during adolescence and early adulthood, regardless of socioeconomic status. These findings highlight the potential cognitive benefits of promoting healthy lifestyles among parents of adolescents.

Objective:To investigate the effect of transorally inserted anvil (OrVil TM) in patients with relapsed or denovo carcinoma at the esophagogastric junction. Methods:The clinical data of 60 patients who underwent radical intent resection for locally relapsed or denovo esophagogastric junction adenocarcinoma at Zhengzhou University Cancer Hospital from Jan 2011 to Jun 2021 were retrospectively analyzed. The patients were divided into two groups according to whether transorally inserted anvil was used. Twenty-six patients who had used the system were assigned to the experimental group. Thirty-four patients without transorally inserted anvil were set to control group.Results:The incisor distance of the experimental group was shorter than that of the control group [36(34-40)cm vs. 39(36-41)cm, Z=-4.948, P<0.05]. Operation time in experimental group was 177 (145-260) min, compared to control group of 172 (140-225) min ( Z=-0.735, P=0.463). Intraoperative blood loss was 200 (100-900) ml in the experimental group and 300 (100-800) ml in the control group ( Z=-1.244, P=0.213). Postoperative upper margin distance of the experimental group was (3.6±1.7) cm compared to control group of (1.8±1.1) cm ( t=-0.735, P<0.01). The positive rate of margin in the experimental group was 4% vs. 15% in the control group ( χ2=1.931, P=0.165). The length of postoperative hospital stay in the experimental group was (18.6±5.2) d vs. (20.5±4.7) d ( t=-1.455, P=0.151). Surgery-related complications developed in 19% in the experimental group vs. 27% in the control group ( P>0.05). Conclusion:The application of the transorally inserted anvil in the operation of patients with locally relapsed or denovo esophagogastric junction cancer after initial operation reduces the difficulty of operation and decreases the positive rate of margin.
