【摘要】 目的 研究改良Paine点侧脑室额角穿刺的解剖基础及临床应用。 方法 利用MRI模型的构建，模拟改良Paine点穿刺侧脑室额角。测量穿刺距离、角度及其对Broca语言功能区和尾状核的影响。改良Paine点（Pm点）比Paine点高1 cm，更加远离Broca语言功能区，穿刺时需要与轴面夹角20°向下，可以越过尾状核头从侧脑室额角上壁进入脑室；与矢状面夹角约70°向下、冠状面夹角约20°向后穿刺。从皮层计算进针4.0~5.5 cm可进入侧脑室额角。 结果 同期7例颅内动脉瘤患者术中应用Pm点穿刺成功，术后无语言功能障碍，复查头颅CT无穿刺道及尾状核头出血现象。 结论 Pm点法定位方法简便准确，能避免Broca语言功能区和尾状核头部的损伤，有一定临床应用推广价值。【Abstract】 Objective To analyze the anatomic characteristics and clinical application of modified Paine entry point (Pm) for lateral ventricular puncture through pterional approach. Methods We simulated the modified Paine entry point for lateral ventricular frontal horn puncture by reconstructing the model of MRI. Distance and angles of the puncture path were measured to evaluate the influence upon the language areas of Broca and the head of the caudate nucleus. The Pm point is 1 cm higher than the Paine point, so it is more far away from the Broca area. The direction of the puncture path should be 20° downward with the axial plane, 70° downward with the sagittal plane and 20° backward with the coronal plane. The catheter was inserted into the ventricle 4.0 to 5.5 cm deep to the cortex. Results Seven patients with intracranial aneurysms underwent ventricular puncture successfully through the Pm point in operation. None of them suffered language dysfunction or hemorrhage lesions in the caudate nucleus by the computed tomography. Conclusion The modified Paine entry point can be located accurately and has the clinical value for preventing damage of the Broca area and the caudate nucleus.
Objective To develop a novel methylene blue staining technique to localize small esophageal leiomyomas (<1.5 cm) and evaluate its feasibility. Methods Between January 2013 and October 2016, 9 patients with small esophageal leiomyomas (<1.5 cm) underwent thoracoscopic enucleation in Tongji Hospital. There were 5 males and 4 females with an average age of 51 years. We preoperatively injected 0.5–1.0 ml methylene blue in the submucosa adjacent to the tumors under the guidance of gastroscope. Then, we transferred the patients to the operating room. Results Staining was successful in 9 patients. The unstained tumor was exposed after the blue-stained mediastinal pleura and overlying muscle were incised longitudinally during video-assisted thoracoscopic surgery via one utility port. No abnormalities were detected in the esophageal mucosa. No major complications, such as esophageal leakage or esophageal diverticulum occurred. Conclusion Endoscopic methylene blue staining is safe and feasible for localizing small esophageal leiomyomas during video-assisted thoracoscopic surgery via one utility port. This method will enable enucleation precise and easy.
ObjectiveTo investigate the status of roxadustat in patients undergoing maintenance peritoneal dialysis and analyze the factors affecting drug compliance. MethodsPatients with renal anemia undergoing maintenance peritoneal dialysis in West China Hospital of Sichuan University from July 2020 to March 2021 were selected. All patients took roxadustat orally. According to the medication compliance, the patients were divided into good compliance group and poor compliance group. The general information questionnaire and Morisky Medication Adherence Scale-8 (MMAS-8) were used to investigate and analyze the included patients, and their clinical examination indexes were collected. ResultsA total of 100 patients were included, Including 39 cases (39%) in the good compliance group and 61 cases (61%) in the poor compliance group. The average score of medication compliance of roxadustat was 5.19±1.72. Logistic regression analysis showed that drug cognition [odds ratio (OR)=0.099, 95% confidence interval (CI) (0.027, 0.365), P=0.001], medication troubles/complex protocol [OR=5.330, 95%CI (1.567, 18.132), P=0.007], and adverse drug reactions [OR=5.453, 95%CI (1.619, 18.368), P=0.006] were factors affecting patient compliance. Hemoglobin in the good compliance group was lower than that in the poor compliance group (Z=−2.259, P=0.024); there was no significant difference in other clinical examination indexes (P>0.05). ConclusionsThe overall compliance of oral roxadustat in maintenance peritoneal dialysis patients is poor, and the corresponding follow-up management system should be improved. Nurses should provide comprehensive and systematic medication guidance to patients, encourage them to fully understand the clinical manifestations, treatment schemes and prognosis of renal anemia, clarify the time, dose, possible adverse reactions and mitigation methods of roxadustat, etc., and help them to treat the disease with correct cognition and attitude, so as to improve their drug compliance.
