大肠癌组织中VEGF、MIF的表达及临床意义

目的：探讨大肠癌组织中血管内皮生长因子（VEGF）及人巨噬细胞游走抑制因子（MIF）的表达及临床意义。方法选取80份经手术切除并经病理证实为大肠癌的组织蜡块（观察组）及80份距癌肿边缘5cm以上经病理证实无癌细胞残存的正常大肠组织（对照组）,SP法检测VEGF、MIF在大肠癌及正常大肠组织中的表达。结果VEGF,MIF在观察组中阳性率为77．50％、82．50％,在对照组阳性率为22．50％、27．50％,观察组阳性率明显高于对照组,差异有统计学意义（P＜0．05）。VEGF、MIF在大肠癌组织中的表达与肿瘤的浸润深度、淋巴结转移、临床分期相关,与性别、年龄、组织学分化无关。结论VEGF、MIF在大肠癌组织中高表达。     

冠心病人心房收缩时间间期测定及其意义

以心阻抗图法对52例冠心病人进行心房收缩时间间期(ASTI)的测量,并与100例同龄组正常人对比,结果表明:冠心病人心房射血前时间缩短(P<0.01),心房射血时间延长(P<0.01),二者比值下降(P<0.01)。ASTI 对于无创性评定冠心病人心室舒张期顺应性改变是一种简单有效的新方法。

房室间隔缺损的二维超声心动图临床及X线分析

本文报告运用二维超声心动图技术,结合临床和X线检查,诊断房室间隔缺损54例,手术证实15例。结果表明:二维超声心动图对诊断房室间隔缺损具有重要价值。在进行这项检查时,如结合做超声造影、临床和X线表现,对较小的房室间隔缺损也能得到明确诊断。     

Giant cervical goiter in Hashimoto’s thyroiditis: A case report

A giant cervical goiter, defined as a thyroid mass larger than 8 cm in diameter, is usually a nodular or adenomatous goiter. A giant cervical goiter can also be caused by hyperthyroidism (i.e., Hashimoto’s thyroiditis). The surgical indications for patients with Hashimoto’s disease include suspected malignant tumors, persistent symptoms related to the disease, or persistent enlargement of the goiter. We herein describe a woman who developed symptoms of compression from a thyroid tumor, the volume of which was almost the largest reported in the relevant literature to date. The bilateral lobes of the giant thyroid tumor were removed by total en bloc excision. We protected the bilateral recurrent laryngeal nerve and preserved the bilateral upper and lower parathyroid glands in situ. The excised left lobe tumor was 16 × 9 × 5.5 cm, whereas the right lobe tumor was 12 × 8 × 4 cm. The pathological diagnosis was Hashimoto’s thyroiditis. Although surgical excision is difficult, it is still the main treatment modality for giant goiters in patients with Hashimoto’s thyroiditis and can help to reduce the occurrence of complications.     

联合应用取栓术及动脉溶栓治疗158例急性下肢动脉栓塞

[背景]探讨球囊导管取栓术及动脉置管溶栓联合应用治疗下肢动脉栓塞的效果.[病例报告]利用球囊导管给158例急性下肢动脉栓塞患者进行下肢动脉取栓术,术后在动脉内留置导管,持续滴入溶栓药物,连续2～4d.治疗成功者为128例(81.0%),好转为20例(12.7%),有效率为93.7%(148/158);截肢者为7例(4.2%);所有患者术后踝臂指数提高为0.75～0.90,平均为0.83;未见穿刺部位明显血肿及球囊扩张导致夹层形成等并发症发生.[讨论]下肢动脉取栓术及置管溶栓联合应用对下肢动脉栓塞治疗有明显的效果.     

胆石症胆道感染并发心包积脓7例分析

本院26年中胆石症、胆道感染并发心包积脓7例。其中6例死亡,作者指出,凡胆石症并感染的患者出现心肺症状和体征,应警惕本并发症的发生。A型超声和X线检查对诊断有重要帮助。一旦确诊应及时行心包穿刺抽脓或心包造口引流;及时有效地处理胆道原发病灶是预防和减少本并发症的根本措施。     

Arthroscopic Intra‐Articular Repair of the Torn Subscapularis Tendon with Single Anterior Portal,Single Suture Anchor,and X‐Shaped Fixation Technique

Subscapular tendon plays an important role in shoulder joint function. With the advance of magnetic resonance imaging technology and the popularization of arthroscopic shoulder surgery, subscapularis tears have been increasingly detected. However, reduction and fixation of subscapular tendon tears appears to be technically challenging. This study aims to describe an arthroscopic intra‐articular X‐shaped fixation technique: a procedure of subscapularis tendon repair performed with the aid of a suture passer using only a single anterior portal and a single suture anchor. By incorporating the advantages of a single anterior working portal for anchor placement and tear repair, this technique provides an easier way to use suture lasso and make knots in a limited working space, and the whole procedure is minimally invasive with a short learning curve. This technique has been applied in patients with subscapularis tears involving no intraoperative or postoperative complications. Our technology offers a valuable new treatment option for subscapularis tears.     

Effects of Kangdaxin on myocardial fibrosis in heart failure with preserved ejection fraction rats

BackgroundThis study aimed to explore the effects of Kangdaxin oral liquid on myocardial fibrosis in heart failure with preserved ejection fraction (HFpEF) rats.MethodsA total of 30 Sprague Dawley (SD) rats were randomly divided into 3 groups Sham operation group (Sham), HFpEF group (HFpEF), and HFpEF with drug intervention group (HFpEF + I). Rats in HFpEF + I group were given Kangdaxin oral liquid at a dose of 2.7 mL/(kg·d). After modeling or treatment, the value of E/A and E/e'' in each group of rats were measured by echocardiography. The N-terminal pro b-type natriuretic peptide (NT-proBNP) level was determined by enzyme-linked immunosorbent assay (ELISA). Heart weight/body mass index (Hw/W) and left ventricular weight/body mass index (LVw/W) were calculated after the rats were sacrificed; the transforming growth factor-β1 (TGF-β1) protein expression level in cardiac tissue was detected by western blot.ResultsCompared with sham group, the values of diastolic function item (E/A) and mitral annular early diastolic velocity (E/e'') in HFpEF group were significantly decreased, and the level of NT-proBNP was significantly increased (P<0.05). Compared with HFpEF group, the value of E/A and E/e'' in HF + I group were significantly increased, and the level of NT-proBNP was significantly decreased (P<0.05). Compared with sham group, the expression of TGF-β1 protein in heart tissue of HFpEF group were significantly increased (P<0.05). Compared with HFpEF group, the expression of TGF-β1 protein in HFpEF + I group were significantly decreased (P<0.05).ConclusionsKangdaxin oral liquid has protective effect on heart in HFpEF rats, which can reduce the protein expression of TGF-β1 in the heart tissue of HFpEF rats. This may be a possible mechanism to inhibit myocardial fibrosis and improve cardiac diastolic function.
