The effect of bevacizumab combined with chemotherapy on the levels of MSH2,MLHI,MSH6 and PMS2 in patients with advanced colorectal cancer

:809-814
 
       目的   分析贝伐珠单抗与化疗对晚期结直肠癌患者4种错配修复蛋白(MSH2、MLHI、MSH6、PMS2)水平影响。方法   选择2022年1月—2024年1月江苏省宿迁市中医院肿瘤科102例晚期结直肠癌患者,按抽签法分成两组,即化疗组及联合组,各51例。化疗组应用FOLFOX(亚叶酸钙+奥沙利铂+氟尿嘧啶)方案进行化疗,联合组采取贝伐珠单抗联合FOLFOX方案治疗。对比其肿瘤控制效果、免疫功能及MSH2、MLHI、MSH6和PMS2水平变化,并对比组间不良反应发生率。结果   联合组客观缓解率、疾病控制率高于化疗组(P<0.05);治疗后联合组患者CD4+ 、CD3+ 、CD8+ 、和CD4+ /CD8+数值高于化疗组,且两组治疗后均低于治疗前(P<0.05);治疗后两组患者MSH2、MLHI、MSH6和PMS2缺失率对比无统计学意义(P>0.05),但其阳性、阴性表达情况对比差异有统计学意义,联合组MSH2、MLHI、MSH6和PMS2阳性率低于化疗组(P<0.05);两组不良反应发生率对比差异无统计学意义(P>0.05)。结论   对晚期结直肠癌在化疗基础上增加贝伐珠单抗抗肿瘤效果显著,改善其免疫功能,虽无法改善患者错配修复蛋白缺损,但可辅助降低其阳性率,且不影响安全性。
       Objective  To analyze the effects of bevacizumab and chemotherapy on the levels of four mismatch  repair proteins(MSH2,MLHI,MSH6,PMS2)in patients with advanced colorectal cancer.Methods  A total of 102 patients with advanced colorectal cancer from the Oncology Department of Suqian Traditional Chinese Medicine Hospital in  Jiangsu Province from January 2022 to January 2024 were selected,and were divided into two groups according to the drawing method,namely the chemotherapy group and the combination group,with 51 patients in each group.The chemotherapy group received FOLFOX(calcium folinate+oxaliplatin+fluorouracil)regimen for chemotherapy,while the combination group received bevacizumab combined with FOLFOX regimen for treatment.Tumor control effect,immune function,and changes in MSH2,MLHI,MSH6,and PMS2 levels,and its incidence of adverse reactions were compared.Results  The objective remission rate and disease control rate of the combined group were higher than those of the chemotherapy group(P<0.05).After treatment,the CD4+ ,CD3+ ,CD8+ and CD4+ /CD8+ values in the combination group were higher than those in the chemotherapy group,and those after treatment were lower than those before treatment in both groups(P<0.05).After treatment,there were no significant differences in the deletion  rates of MSH2,MLHI,MSH6,and PMS2 between the two groups of patients(P>0.05),but there was a significant difference in their positive and negative expression.The positive rates of MSH2,MLHI,MSH6,and PMS2 in the combination group were lower than those in the chemotherapy group(P<0.05).There was no significant difference in the incidence of adverse  reactions between the two groups(P>0.05).Conclusions  Adding bevacizumab on the basis of chemotherapy has a significant anti-tumor effect on advanced colorectal cancer,improving its immune function.Although it cannot improve the mismatch  repair protein defect in patients,it can assist in reducing its positivity rate and has high safety.

:644-649
 
       目的   探讨NXT629改善肝胆结石形成的相关机制。方法   对C57BL/6J小鼠分别采用常规饮食或成石饮食(LD)喂养,并在LD组小鼠注射PPAR-α拮抗剂NXT629。通过苏木精-伊红染色法染色分析肝脂肪病变,油红O染色检测肝脏脂质的积累,分光光度法检测胆汁或血清中总胆固醇、甘油三酯、磷脂、总胆汁酸、胆固醇饱和指数、低密度脂蛋白胆固醇、高密度脂蛋白胆固醇指标;qPCR法检测小鼠肝组织中ABCG5/8、CYP7A1、CYP7B1、PPAR-α和ABCB11 mRNA的表达情况。结果  NXT629通过靶向PPAR-α降低LD组小鼠肝脏中的ABCG5、ABCG8、ABCB11 mRNA水平以及增加CYP7A1、CYP7B1 mRNA水平,进而减少LD诱导的肝胆结石形成并改善脂质代谢紊乱。结论  NXT629可能通过影响脂代谢相关基因表达改善肝胆结石。

CD28 和 PD-1 在自发性脑出血预后中的研究进展

Research progress of CD28 and PD-1 in the prognosis of spontaneous intracerebral hemorrhage

:446-451
 
       自发性脑出血(SICH)是脑卒中的一种常见形式,其预后通常较差,因此早期评估和调节患者出血后的免疫状态至关重要。免疫检查点是评估T淋巴细胞活跃性和增殖状态的关键指标,监测这些检查点有助于预测脑出血患者的预后。程序性死亡蛋白1(PD-1)和细胞分化抗原28(CD28)作为两个典型的免疫检查点,它们在脑出血预后评估中的应用正逐渐成为研究的热点。该文综述了脑出血后机体免疫状态的变化,以及PD-1和CD28在脑出血后评估和治疗中的研究进展。
       Spontaneous intracerebral hemorrhage(SICH)is a common cause of stroke,with  specific outcomes often being poor.Therefore,early assessment and modulation of the immune status after hemorrhage are of critical importance.Immune checkpoints serve as key indicators for assessing the activation and proliferation of T cells,and monitoring these checkpoints can help to predict the outcomes of patients with intracerebral hemorrhage.PD-1(programmed death 1)and CD28(Cluster of Differentiation 28)are two representative immune checkpoints,and their use in prognostic assessment after intracerebral hemorrhage is becoming a focus of research.This article reviews the changes in the immune state of the body after intracerebral hemorrhage,as well as the research progress on the use of PD-1 and CD28 in the evaluation and treatment following intracerebral hemorrhage.

2 型糖尿病合并骨质疏松的药物治疗进展

Advances in the pharmacologic treatment of type 2 diabetes mellitus combined with osteoporosis

:316-322
 
       随着糖尿病发病率不断攀升,人们逐渐聚焦于糖尿病合并骨质疏松。围绕此疾病,国内外学者开展了广泛而深入的研究,临床实践聚焦于两点:糖尿病的精准治疗和骨质疏松的有效干预。在确保血糖稳定的基础上,致力于抑制骨吸收、促进骨形成。在此治疗理念指导下,临床医生应当更加全面了解血糖管理与抗骨质疏松药物的作用机制并合理应用,更大程度改善患者的临床症状及预后。然而,药物作用机制复杂,联合应用存在潜在药物相互作用问题。未来研究方向包括探索更安全有效的联合治疗方案,更加精确化地治疗以提高临床疗效。文章分析了降糖药物及抗骨质疏松药物对疾病的疗效,并展望未来的研究方向,旨在为临床实践提供更为深刻与全面的指导。
    As the incidence of diabetes mellitus continues to rise,people are also gradually focusing on diabetes mellitus combined with osteoporosis,which puts patients at a higher risk of fragility fracture.Scholars at home and abroad have conducted extensive and in-depth research around this condition,and clinical practice has focused on two points:first,the precise treatment of diabetes,and second,the effective intervention of osteoporosis.On the basis of ensuring blood glucose stabilization,we are committed to inhibiting bone resorption and promoting bone formation.Under the guidance of this therapeutic concept,we should have a more comprehensive understanding of the mechanism of action of blood glucose management and anti-osteoporosis drugs and apply them rationally,aiming to improve the clinical symptoms and prognosis of patients to a greater extent through dual intervention.However,the mechanism of action of different drugs is complex,and there are potential drug-drug interactions and safety issues associated with their combined use.Future research directions should include exploring  safer and more effective combination therapies,developing novel drugs,and more precise and individualized treatments to improve clinical efficacy.This article analyzes the efficacy of glucose-lowering drugs and anti-osteoporosis drugs on the disease and looks forward to future research directions,aiming to provide more profound and comprehensive guidance for clinical practice.

老年慢性心力衰竭患者血清 SCD-1 和 sVEGFR-2 表达水平及其与预后的评估价值研究

Expression levels of serum SCD-1 and sVEGFR-2 in elderly patients with chronic heart failure and their prognostic value

:241-246
 
       目的   探究血清多配体蛋白聚糖-1(SCD-1)与可溶性血管内皮生长因子受体-2(sVEGFR-2)表达水平在老年慢性心力衰竭患者预后评估的判定价值。方法   选取2023年1月—2024年3月珠海市第五人民医院检验科收治的110例老年慢性心力衰竭患者,检测其血清SCD-1和sVEGFR-2水平,对患者进行随访调查,了解其再次由于心力衰竭住院、心源性死亡的情况。运用多因素Logistic回归分析,探究老年慢性心力衰竭患者预后影响因素。结果  Logistic回归分析显示,心功能分级(OR=3.433,95%CI:0.934~6.431)、B型脑钠肽升高(OR=2.462,95%CI:0.861~4.765)、血清SCD-1升高OR=3.795,95%CI:0.972~6.894)、血清sVEGFR-2升高(OR=3.842,95%CI:0.942~6.912)为影响老年慢性心力衰竭患者预后不良的重要因素(P<0.05);联合血清SCD-1和sVEGFR-2曲线下面积0.962与B型脑肽钠曲线下面积0.844,相较于单一SCD-1曲线下面积0.658、sVEGFR-2曲线下面积0.712明显偏高(P<0.05)。结论   经研究证实,老年慢性心力衰竭患者预后效果不理想,其血清SCD-1和sVEGFR-2监测水平异常升高,和老年慢性心力衰竭预后不佳存在关联性,可视为老年慢性心力衰竭患者判定预后效果的主要标志物。
      Objective  To investigate the prognostic value of serum syndecan-1(SCD-1)and soluble vascular endothelial growth factor receptor-2(sVEGFR-2)expression levels in elderly patients with chronic heart failure.Methods  A total of 110 elderly patients with chronic heart failure admitted to our hospital were selected,with a time interval of January 2023 to March 2024.Serum SCD-1 and sVEGFR-2 levels were detected and follow-up investigations were conducted to understand their re hospitalization and cardiogenic death due to heart failure.Multiple logistic  regression analysis was used to explore the prognostic factors affecting elderly patients with chronic heart failure.Results  According to logistic retrospective analysis,heart function grading(OR=3.433,95%CI:0.934-6.431),elevated B-type brain natriuretic peptide(OR=2.462,95%CI:0.861-4.765),elevated serum SCD-1(OR=3.795,95%CI:0.972-6.894),and elevated serum sVEGFR-2(OR=3.842,95%CI:0.942-6.912)were important factors affecting the poor prognosis of elderly patients with chronic heart failure,with differences P<0.05.The area under the curve of combined serum SCD-1 and sVEGFR-2 was 0.962,and the area under the curve of B-type brain peptide sodium was 0.844,which was significantly higher than that of a single SCD-1 curve of 0.658 and sVEGFR-2 curve of 0.712,with a difference of P<0.05.Conclusions  Research has confirmed that the prognosis of elderly patients with chronic heart failure is not satisfied,and their serum SCD-1 and sVEGFR-2 monitoring levels are abnormally elevated,which is related to the poor prognosis of elderly patients with chronic heart failure.It can be regarded as the main biomarker for defining the prognosis of elderly patients with chronic heart failure.
