Objective To observe the clinical efficacy of lansoprazole enteric-coated tablets combined with flupentixol-melitracen in treating anxiety patients with erosive gastritis. Methods 106 patients with erosive gastritis and anxiety in our hospital from January 2013 to January 2015 were divided into an observation group and a control group, with 53 patients in each group. The control group was given lansoprazole enteric-coated tablets alone, and the observation group was treated with lansoprazole enteric-coated tablets and flupentixol-melitracen. Clinical symptoms and mucosal erosion were compared between the two groups of patients before and after treatment. Gastric mucosa malondialdehyde (MDA) and prostration E2 (PGE2) contents, anxiety and depression status were also assessed. Results After treatment, the scores of abdominal pain, bloating, acid reflux, belching, and mucosal erosions were significantly lower in the observation group than in the control group (P< 0.05). PGE2and MDA contents in the gastric mucosa in the observation group were different from those in the control group(P< 0.05). HAMA and HAMD scores were lower in the observation group than in the control group (P< 0.05). There was no difference of adverse reaction rate between the control group and the observation group (P>0.05). Conclusion Lansoprazole enteric-coated tablets combined with flupentixol-melitracen has better clinical efficacy than lansoprazole enteric-coated tablets only in patients with erosive gastritis and anxiety in terms of the improvement of clinical symptoms and mucosal erosion and the relief of negative emotions.

目的 探讨纵隔髓外造血(EMH)的临床特点,从而为其诊断、治疗提供参考意见。方法 总结分析我科收治的1例双侧后纵隔骨髓外造血组织多发瘤样增生,并对近10年来国内相关文献报道的27例病例进行回顾性分析。结果 患者需行手术活检取得病理诊断,确诊髓外造血。结论 纵隔髓外造血瘤样增生是一种罕见特殊的良性病变, 预后良好。但因其临床表现和影像学均缺乏特异性,当临床中遇到发生在后纵隔脊柱旁的占位性病变,同时患有贫血的患者应考虑EMH 的可能性,给予经皮穿刺或者胸腔镜下活检来取得细胞学诊断,从而避免不必要的手术治疗。

Objective To probe into the clinical features of mediastinal extramedullary hematopoiesis (EMH), for providing a reference for clinical diagnosis and treatment. Methods The clinical data was studied in a case of mediastinal EMH from our department, and 27 case reports from domestic published literatures over the last decade were analyzed retrospectively. Results Of the 27 patients, 15 received surgical excision, while the other 12 underwent needle biopsy. In our patient, the diagnosis of EMH was made by mini thoracotomy and open biopsy. Conclusion Mediastinal EMH is a rare disease and its prognosis is well. Because there is no obvious specific clinical symptoms and imaging appearances, the possibility of EMH should be considered when a patient with a mediastinal tumor associated with anemia is encountered. Diagnosis can be achieved by needle biopsy or video-assisted thoracic surgery (VATS) in order to prevent unnecessary surgical procedures.

目的 分析乳腺癌细胞中Snail与MTDH基因的作用,明确Snail是否通过结合于MTDH的启动子区域促进乳腺癌转移。方法 克隆、转染Snail基因至乳腺癌细胞,观察过表达Snail的乳腺癌细胞中MTDHmRNA及蛋白表达的变化;再使用免疫共沉淀法检测Snail与MTDH基因的共作用。结果 转染Snail基因进入乳腺癌MDA-MB-435细胞后,转染组、空白组和对照组中MTDHmRNA的表达水平分别为1.61±0.22、1.02±0.18、0.99±0.20,转染组高于空白组和对照组,差异有统计学意义(P<0.05),而后两组表达无差异(P>0.05);Westren blot检测结果显示,Snail可促进MTDH蛋白的表达;免疫共沉淀显示,Snail与MTDH在细胞内存在相互结合作用。结论 Snail在乳腺癌细胞中可通过结合于MTDH基因的启动子区域,促进MTDHmRNA转录及相关蛋白的表达,从而导致乳腺癌转移。

Objective To investigate the function of Snail to MTDH gene in breast cancer cells. Methods We observed the changement of MTDHmRNA and protein expression in breast cancer cell line MDA-MB-435 after transfected with Snail gene. Then, we used co-immunoprecipitation to determine the domain of Snail and MTDH binding in vitro. Results After transfected with Snail gene into MDA-MB-435 cell, the expression levels of MTDHmRNA in transfection group, blank group and control group were 1.61±0.22,1.02±0.18,0.99±0.20. The level of transfection group was significantly higher than the other groups(P< 0.05). Western blot showed that the expression of MTDH protein can be promoted by Snail. Co-immunoprecipitation showed that Snail and MTDH are binding interactions in breast cancer cell line MDA-MB-43. Conclusion Snail can promote transcription and expression of MTDH in breast cancer cells by binding to the promoter region of the MTDH gene resulting in metastasis of breast cancer.

        胃食管反流病是一种以烧心和反流为主要症状的胃食管动力障碍性疾病，现有的常规治疗存在药物依赖，手术风险高且易复发等局限性，而经皮电刺激作为一种新兴疗法，在治疗动力障碍性疾病时具有非侵入性、可逆性及调节生理功能的优势。因此本研究为了探讨经皮电刺激治疗胃食管反流病的进展，现从胃食管反流病的神经调控生理、不同经皮电刺激对治疗胃食管反流病的研究以及应用效果等方面进行综述，以期为胃食管反流病提供新的诊断思路和方法。

       目的   探讨谷氨酸对HT22细胞线粒体自噬和细胞凋亡的影响，并评估虾青素预处理的保护作用及其分子机制。方法   用谷氨酸及虾青素处理HT22细胞，通过蛋白印迹及聚合酶联反应等评估其对线粒体自噬的影响。结果   谷氨酸处理显著抑制线粒体初级自噬（PINK1、Parkin、pULK1^ser555和LC3Ⅱ）和次级自噬（LAMP1和Rab7），上调cleaved Caspase-3的表达（P＜0.05）。虾青素预处理减少细胞凋亡，恢复了线粒体自噬，PINK1、Parkin、pULK1^ser555和LC3Ⅱ的表达水平上升（分别为2.3倍、2.6倍、83.3%及81.1%）（P＜0.05），该作用被自噬抑制剂BafA1阻断。此外，谷氨酸抑制Nrf2核内转移和NLRX1表达，而预处理显著促进Nrf2的核内转移并上调NLRX1，分别上调25.8%、33.2%。生物信息学分析显示NLRX1启动子区域含有3个Nrf2结合位点，提示Nrf2通过调控NLRX1转录活性发挥作用。结论   文章揭示虾青素通过Nrf2/NLRX1通路激活线粒体自噬，展现神经保护作用。

       目的   探讨与分析实时图像引导系统对乳腺癌保乳术后放射治疗（放疗）摆位误差的影响。方法   选取安阳市肿瘤医院2021年9月—2023年12月收治的乳腺癌保乳术后108例患者为研究对象，按照随机信封抽签法把108例患者分为实时组54例与对照组54例。两组的放疗观察时间均为3个月，对照组给予热塑体模定位，实时组给予实时图像引导系统定位，记录两组的摆位误差与放疗不良反应发生情况。结果   实时组X轴、Y轴、Z轴方向的配准结果误差发生率分别为1.85%、7.41%、1.85%，均低于对照组的14.81%、22.22%、16.67%（χ ² =5.939，P=0.015；χ ² =4.696，P=0.030；χ ² =7.053，P=0.008）。实时组摆位纠正前X轴、Y轴、Z轴误差大于对照组（t分别为38.888、28.106、50.102，P＜0.05），摆位纠正后两组摆位误差对比差异无统计学意义（P＞0.05）。实时组放疗3个月期间的心脏平均受量、肺脏平均受量均少于对照组（t分别为49.942、13.996，P＜0.001）。实时组放疗3个月期间的急性放射性皮肤反应发生率为3.70%，对照组为16.67%，实时组低于对照组（χ ² =4.960，P＜0.05）。结论   实时图像引导系统在乳腺癌保乳术后放疗的应用可减少摆位误差，也能减少患者的心脏平均受量、肺脏平均受量，降低急性放射性皮肤反应发生率。

       Objective  To investigate and analysis the effects of image-guided radiation therapy on the positioning error of radiotherapy after breast conserving surgery for breast cancer．Methods  from September 2021 to December 2023，108 patients with breast cancer after breast conserving surgery in Anyang Cancer Hospital were selected as the study subjects．According to the principle of random envelope drawing，108 patients were divided into the real-time group of 54 patients and the control group of 54 patients．The observation time for radiotherapy in both groups was 3 months．The control group was given thermoplastic phantom positioning，while the real-time group was given image-guided radiation therapy positioning．The positioning errors and incidence of radiotherapy adverse reactions were recorded in both groups．Results  The error rates of registration results in the X-axis，Y-axis，and Z-axis directions of the real-time group were 1.85%，7.41% and 1.85%，respectively，which were significantly lower than the control group（14.81%，22.22% and 16.67%；χ ² =5.939，P=0.015；χ ² =4.696，P=0.030；χ ² =7.053，P=0.008）．The errors in the X-axis，Y-axis and Z-axis before the pendulum correction were greater than that in the control group（t=38.888，28.106，50.102，P＜0.05），and there were no statistically significant difference in positioning errors compared between the two groups after positioning correction（P＞0.05）．The average cardiac and lung uptake during the 3-month period of real-time radiotherapy in the group were significantly lower than those in the control group（t=49.942，13.996，P＜0.001）．The incidence of acute radiation-induced skin reactions during the 3-month period of real-time group radiotherapy was 3.70%，compared to 16.67% in the control group，the real-time group showed a significant decrease（χ ² =4.960，P=0.026＜0.05）．Conclusions  The application of image-guided  radiation therapy in radiotherapy after breast conserving surgery for breast cancer can reduce the positioning error，the average cardiac and pulmonary dose，and the incidence of acute radiation skin reaction．
