Objective To explore the relationship between peripheral blood T lymphocyte subsets and prognosis of patients with advanced non-small cell lung cancer (NSCLC) who received treatment with camrelizumab. Methods We retrospectively collected data from 88 patients with advanced NSCLC who underwent camrelizumab treatment. Peripheral blood lymphocyte subsets were collected from patients before and two months after treatment. Kaplan-Meier curves and Cox regression analysis were employed to investigate the relationship between peripheral blood T lymphocyte subsets and PFS and OS. Results Compared with non-responder group, the baseline peripheral blood CD4+/CD8+ ratio was higher (P=0.038), while the CD8+T lymphocyte percentage was lower (P=0.036) in the responder group. Kaplan-Meier curves showed that a high baseline CD4+/CD8+ ratio was associated with long PFS and OS (P=0.001, P=0.023). Multivariate Cox analysis revealed that the baseline CD4+/CD8+ ratio was a significant predictor for PFS and OS. Additionally, a high post-treatment CD4+/CD8+ ratio and high CD4+T lymphocyte percentage were associated with long PFS (P=0.005, P=0.015), whereas a low post-treatment CD8+T lymphocyte percentage was associated with long PFS and OS (P=0.001, P=0.016). Conclusion The peripheral blood CD4+/CD8+ ratio can serve as a predictive factor for survival of patients with NSCLC treated with camrelizumab.

Objective To study the effectiveness of pro-abdominal exercise in improving the quality of gastroscopy,and provide patients with a better preoperative preparation for gastroscopy.Methods 307 patients who underwent painless gastroscopy from March to July 2023 were selected and divided into three groups according to the random number table method.There were 106 cases in the abdominal massage group,103 cases in the bed turning group and 98 cases in the control group.On the basis of routine medication,different preoperative activity guidance was used to compare and analyze the preoperative preparation time,examination time and gastric mucosal visual field clarity score in each group.Results The gastroscopy time in the abdominal massage group and the bed-turning group was significantly shorter than that in the control group,and the clarity score of the gastric mucosal visual field was significantly lower than that of the control group,with statistically significant differences(P<0.05).However,there were no statistically significant differences in the gastroscopy time or visual field clarity score for gastric body,gastric fundus,and gastric antrum between the abdominal massage group and the bed-turning group(P>0.05).The satisfaction rate of endoscopists in the abdominal massage group and the bed turning group was higher than that in the control group,and the differences were statistically significant.Conclusion Abdominal massage and turning over in bed as preoperative preparation methods for gastroscopy can improve the quality of gastroscopy,while abdominal massage can shorten the preparation time before gastroscopy,which is helpful for the efficient operation of digestive endoscopy center and is worthy of clinical application.

The TEA domain (TEAD) family proteins (TEAD1‒4) are essential transcription factors that control cell differentiation and organ size in the Hippo pathway. Although the sequences and structures of TEAD family proteins are highly conserved, each TEAD isoform has unique physiological and pathological functions. Therefore, the development and discovery of subtype selective inhibitors for TEAD protein will provide important chemical probes for the TEAD-related function studies in development and diseases. Here, we identified a novel TEAD1/3 covalent inhibitor (DC-TEADin1072) with biochemical IC

PURPOSE: Although the effect of lysosome-associated protein transmembrane 4 beta (LAPTM4B) on the proliferation, migration, and invasion of breast cancer (BC) cells has already been studied, its specific role in BC progression is still elusive. Here, we evaluated the effect of different levels of LAPTM4B expression on the proliferation, invasion, adhesion, and tumor formation abilities of BC cells in vitro, as well as on breast tumor progression in vivo. METHODS: We investigated the influence of LAPTM4B expression on MCF-7 cell proliferation, invasion, adhesion, and tube formation abilities in vitro through its overexpression or knockdown and on breast tumor progression in vivo. RESULTS: Cell growth curves and colony formation assays showed that LAPTM4B promoted the proliferation of breast tumor cells. Cell cycle analysis results revealed that LAPTM4B promoted the entry of cells from the G1 into the S phase. Transwell invasion and cell extracellular matrix adhesion assays showed that LAPTM4B overexpression increased the invasion and adhesion capabilities of MCF-7 cells. More branches were observed in MCF-7 cells overexpressing LAPTM4B under an electron microscope. In comparison with LAPTM4B overexpression, LAPTM4B knockdown decreased the expression of vascular endothelial growth factor-A and significantly inhibited the vasculogenic tube formation ability of tumors. These results were also verified with western blot analysis. CONCLUSION: LAPTM4B promoted the proliferation of MCF-7 cells through the downregulation of p21 (WAF1/CIP1) and caspase-3, and induced cell invasion, adhesion, and angiogenesis through the upregulation of hypoxia-inducible factor 1 alpha, matrix metalloproteinase 2 (MMP2), and MMP9 expression. This specific role deems LAPTM4B as a potential therapeutic target for BC treatment.

Objective To investigate the effects of dihydropteridine reductase (QDPR) on regulating apoptosis induced by plamitic acid(PA). Methods The transfection of HEK293T cells experiment was divided into 3 groups. A group was the control vector group. B group was the control vector group induced by PA. C group was the recombinant plasmid QDPR group induced by PA. First, control vector and recombinant plasmid QDPR was respectively transfected into HEK293T cells. After 24 h, PA with concentration of 0. 5 mmol/L was added into the medium of above cells. The cells of control vector group, the cells of control vector group induced by PA and the cells of recombinant plasmid QDPR group induced by PA were cultured for another 24 hours. At last, cells were harvested to detect tetrahydrobiopterin (BH4) and reactive oxygen species(ROS) generation, Beclin 1, Caspase 3 and Beclin 2 expression. Results ① After transfection, the recombinant plasmid QDPR was successfully constructed and expressed in cells.② There was no significant difference between A group and B group in BH4 generation. Compared with B group, BH4 generation increased in C group (P < 0. 05).③ ROS generation was increased in B group compared with A group, and decreased ROS generation in C group compared with B group (P < 0. 05).④ Western blot analysis revealed that Beclin 1 and Caspase 3 increased (P < 0. 05 ) while Beclin 2 decreased in B group compared with A group (P < 0. 05). Compared to B group, Beclin 1 and Caspase 3 decreased while Beclin 2 increased in C group (P < 0. 05 ). Conclusion QDPR may regulate apoptosis induced by fatty acids by decreasing the generation of ROS and increasing the level of BH4 and the expression of Beclin 2 associated with anti-apoptosis.

Objective To investigate the effect of anti-human immunoglobulin M (IgM) on proliferation,apoptosis,cell cycle and tumor formation in human nasopharyngeal carcinoma HNE-1 cell line in vitro and in vivo.Methods After treatment with anti-human IgM antibody,proliferation of HNE-1 cells was observed by cell proliferation inhibition assay,apoptosis and cell cycle of HNE-1 cells were detected by flow cytometry,and apoptotic cells were detected by TUNEL staining.Nude mouse models were constructed,and were injected intraperitoneally with anti-human IgM antibodies (once every 3 days).The growth of transplanted tumor was observed once every 4 days.After the fifth injection,the expression levels of IgM and gp96 protein in transplanted tumor were observed by immunohistochemical method (streptavidin-peroxidase conjugated method,SP).Results MTS assay showed that anti-human IgM antibody can significantly inhibit the proliferation of HNE-1 cells in concentration-and time-dependent manner (P＜0.05).Flow cytometry showed that the anti-human IgM antibody promoted a significant decrease in percentage of cells in G1 phase,a significant increase in percentage of cells in S phase,and a significant increase in apoptotic rate of HNE-1 cells (P＜0.05).TUNEL staining showed that the anti-human IgM antibody promoted apoptosis of HNE-1 cells (P＜0.01).Transplantation tumor experiment showed that anti-human IgM antibody can significantly inhibit the volume and weight of transplanted tumor (P＜0.05).The immunohistochemistry showed that the expression levels of IgM and gp96 proteins in mouse transplanted tumors after intraperitoneal injection with anti-human IgM antibodies were significantly lower than those of the control group (P＜0.05).Conclusion The anti-human IgM anti-body could effectively inhibit the proliferation of HNE-1 cells,promote apoptosis,and arrest cell cycle.Anti-human IgM antibody could also inhibit the growth of transplanted tumor in nude mouse,which might be related to inhibition of the expressions of IgM and gp96 proteins.

Objective To investigate the value of tissue motion mitral annular displacement (TMAD) in assessment of left ventricular systolic synchrony in patients with dilated cardiomyopathy (DCM).Methods Thirty-eight DCM patients and 30 healthy subjects were enrolled in this study.The left ventricular end diastolic volume (LVEDV),left ventricular end systolic volume (LVESV),and left ventricular ejection fraction (LVEF) in two groups were investigated using conventional echocardiographyexamination.The time of systolic mitral annular peak displacement (TP) in two groups were measured by the technique of TMAD at six sites (anteroseptal,posteroseptal,anterior,lateral,posterior and inferior).The standard deviation of TP (TP-SD) and the maximal difference of TP (TP-DIF) were calculated.And the correlation between TP-SD and LVEF as well as TP-DIF and LVEF in the DCM group were analyzed.The standard deviation and maximal difference of the time to point with minimal systolic volume of 16 segments (Tmsv16-SD,Tmsv16-DIF) of the DCM group were measured by the technique of real-time three-dimensional echocardiography (RT-3D).And the correlation between Tmsv-16SD and TP-SD as well as Tmsv16-DIF and TP-DIF were analyzed.Results Compared with the healthy subjects,LVESV and LVEDV increased (t=14.023,16.643,P ＜ 0.01) and the LVEF decreased significantly (t=26.112,P ＜ 0.01) in the DCM group.TP,TP-SD and TP-DIF in the DCM group obviously increased (t=7.628,6.869,7.507,6.616,5.631,4.738,7.368,5.777,6.781,P ＜ 0.01).TP-SD and TP-DIF were negatively correlated with LVEF (r=-0.645,-0.513,P ＜ 0.05),while TP-SD and Tmsv1 6-SD,TP-Dif and Tmsv1 6-Dif were positively correlated(r=0.643,P ＜ 0.01;r=0.563,P ＜ 0.05).Conclusions In this study,the TMAD technique was used to measure the time of peak displacement of mitral annulus to evaluate the synchrony of left ventricle movement.It is expected to be a new method in evaluation of the synchrony of left ventricle,which is simple,feasible approach without angle dependence.
