CT和MRI在诊断鼻内型脑膜脑膨出中的作用

目的：评价CT和MRI在诊断鼻内型脑膜脑膨出中的价值。方法：回顾性分析7例经手术和病理证实鼻内型脑膜脑膨出患者的CT与MRI表现；4例均行CT和MRI扫描,2例仅行CT扫描，1例仅行MRI检查。结果：7例鼻内型脑膜脑膨出患者中有1例并发脑积水。冠状位CT扫描可见筛骨骨质缺损，MRI见鼻腔内囊状异常脑脊液信号，并向上与颅内蛛网膜下腔直接相通，其内有少量脑组织信号。结论：CT和MRI能正确诊断该型脑膜或脑膜脑膨出；CT显示颅底骨质缺损大小、部位优于MRI，MRI可清楚显示疝出物及其与脑底的关系。

The novel infra‐pectineal buttress plates used for internal fixation of elderly quadrilateral surface involved acetabular fractures

ObjectivesIn geriatric acetabular fractures, the quadrilateral surface (QLS) was frequently involved in acetabular fracture patterns and accompanied by medial displacement. It was important to buttress the medial displaced QLS and reconstruct the congruity of the affected acetabulum. To evaluate the clinical effectiveness of the novel infra‐pectineal quadrilateral surface buttress plates for the treatment of geriatric acetabular fractures.MethodsTwenty‐three geriatric patients who were treated for acetabular fractures involving QLS with the novel infra‐pectineal buttress plates (NIBP) through a single supra‐ilioinguinal approach between January 2015 and June 2019 were retrospectively analyzed; all patients received at least 1 year''s follow‐up. All patients were aged ≥60 years old and including 18 males and five females. Radiologic and clinical outcomes of patients involved in the study were collated and analyzed according to the Matta scoring system and the Merle D''Aubigné–Postel scoring system. The functional recovery scoring was compared using q‐test.ResultsAll 23 consecutive patients had relatively satisfactory clinical treatment effectiveness. Average ages, length of incision, operation time, and intraoperative blood loss were 69.8 ± 6.1 years, 12.1 ± 2.6 cm, 166.5 ± 43.5 min, and 500 (500,700) ml, respectively. According to the Matta scoring system, 14 cases of reduction were graded as excellent, five as good, and four as fair. At the last follow‐up, the clinical outcome evaluation was excellent in 13 cases, good in seven cases, and poor in three cases with the use of the Merle D''Aubigné–Postel scoring system. The difference of modified Merle D''Aubigne‐Postel score at 3 months, 6 months and last follow up was statistically significant (F = 21.56, p < 0.05). Postoperative lateral femoral cutaneous nerve injury occurred in three patients and heterotopic ossification occurred in one patient.ConclusionsFor the treatment of geriatric acetabular fractures, the NIBP could provide stable and effective fixation to the QLS involved acetabular fractures, and related satisfactory clinical results with few complications were noted.     

VEGFR3在不同临床分期舌癌癌周淋巴管中的表达

目的:研究血管内皮生长因子受体(VEGFR3)在舌癌淋巴转移中的作用,探索舌癌淋巴转移的机制。方法:采用免疫组化和RT-PCR技术,对90例不同分期的舌癌肿瘤进行VEGFR3的检测,与10例正常舌黏膜标本进行对照。采用SAS6.12软件进行单因素方差分析。结果:通过与正常组对照,Ⅰ、Ⅱ、Ⅲ期肿瘤中VEGFR3的表达无显著性差异(P>0.05),Ⅳ期肿瘤中VEGFR3的表达较正常对照组显著升高并具有显著性差异(P<0.05)。肿瘤各组间比较无显著性差异。转移组与非转移组之间也无显著性差异。结论:VEGFR3参与微淋巴管的生成,随着肿瘤的临床分期增高,其表达虽呈缓慢增高趋势,但尚不足以作为判定是否发生淋巴转移的客观指标。

活血解毒方对缺氧/复氧所致心肌细胞凋亡的影响＊

目的 研究活血解毒方对缺氧/复氧（H/R）所致的心肌细胞凋亡的影响。方法 体外培养H9C2心肌细胞并分成正常对照组（Control组）、缺氧复氧组（H/R组）、H/R + 活血解毒中药组、LY294002组和活血解毒中药 + LY294002组，其中正常对照组给予DMEM培养基培养，缺氧复氧组给予缺氧4 h、复氧6 h处理，缺氧复氧 + 活血解毒中药组、LY294002组和活血解毒中药 + LY294002组分别给予活血解毒中药、LY294002、活血解毒中药配合LY294002预处理24 h，然后均给予缺氧4 h、复氧6 h处理。采用CCK8检测各组心肌细胞的存活率，流式细胞术检测各组细胞凋亡水平，电镜观察各组心肌细胞中线粒体、自噬体的变化，Western Blot检测各组细胞凋亡蛋白半胱氨酸天冬氨酸蛋白酶3（Caspase3）、半胱氨酸天冬氨酸蛋白水解酶3（Cleaved caspase3）、β-连环蛋白（β-Catenin）、p-p65、B淋巴细胞瘤-2（B-cell lymphoma-2，Bcl-2）蛋白的表达。结果 活血解毒方预处理显著增加H/R诱导的H9C2心肌细胞凋亡，降低凋亡相关蛋白Cleaved caspase3、β-Catenin、p-p65表达，增加Bcl-2表达。结论 活血解毒方可通过抑制细胞凋亡，降低缺氧/复氧所致的心肌细胞损伤，其作用机制可能与PI3K信号通路相关。
