年龄与代谢综合征的关系及防治对策

目的了解中老年人群年龄与多种代谢异常的聚集状况,为心脑血管疾病的一级预防提供依据。方法对744例中老年人按不同年龄分为5组,分析代谢综合征(MS)各项指标的变化规律及特点。结果年龄与肥胖呈明显负相关(P<0.001),与高血糖、高血压及冠心病、脑卒中呈明显正相关(P<0.05或0.001);40～60岁组MS的患病率基本一致,约为30%,70岁以后明显增加,到80岁时可高达51%(P<0.05或0.01);MS与冠心病和脑卒中的患病率均明显相关(P<0.05),随着临床指标个数的增加,冠心病的患病率增加了6.8%,脑卒中的患病率增加了7.44%。结论中年人群超重或肥胖的患病率明显高于老年组,应引起足够重视;随着年龄增长,代谢异常指标数目增多,尤其是≥3项指标的人数明显增加;MS作为心血管危险因素直接导致冠心病、脑卒中发病率增加。针对中老年人群MS的特点,制定相应的干预措施十分重要。     

不稳定型心绞痛患者内皮素及血管性假血友病因子的改变

目的 观察不稳定型心绞痛 (Unstableanginapectoris,UAP)患者内皮素 (Endothelin,ET)及血管性假血友病因子 (vonWillebrandfactor,vWF)的变化。方法 不稳定型心绞痛患者34例、正常人21名分别在清晨采血测定ET及vWF值。 结果 不稳定型心绞痛患者ET(129.3±26.4) pg/ml及vWF(185.4±32.4) %值明显高于正常人(85.2±39.6)pg/ml及(142.1±42.0) % ,两者之间不具有显著相关性 (r=0.15,P>0.05)。结论 ET及vWF的改变可能参与了不稳定型心绞痛的病理生理过程。     

腮腺舍格伦综合征与非霍奇金淋巴瘤相关性分析

目的:了解腮腺非霍奇金淋巴瘤与舍格伦综合征的临床及发病机制的相关性，正确诊断和治疗舍格伦综合征，尽早明确有无恶性变。方法：对142例口腔颌面部的非霍奇金淋巴瘤中21例发生在腮腺的非霍奇金淋巴瘤，及3例从合格伦综合征演变成淋巴瘤的病例进行分析。结果：21例腮腺区非霍奇金淋巴瘤的局部表现主要为肿块、反复肿胀，与类肿瘤型舍格伦综合征的一般特征和腮腺表现有相关性，其中3例腮腺淋巴瘤患者有明确的舍格伦综合征病史。结论：舍格伦综合征与腮腺非霍奇金淋巴瘤的发生发展，以及临床表现有相关性，部分类肿瘤型舍格伦综合征可演变为淋巴瘤，临床表现和免疫学改变可早期判断舍格伦综合征有无恶性变。     

Wall-eyed bilateral internuclear ophthalmoplegia from lesions at different levels in the brainstem.

Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is a rarely reported syndrome. There is dispute about whether WEBINO is caused by a pontine or a midbrain lesion and whether the medial rectus subnuclei are implicated. In a study of the clinical and imaging features of four patients with WEBINO, we found that that three of four lesions involved the midbrain but not necessarily the medial rectus subnuclei.     

神经外科麻醉对体感诱发电位的影响

目的探讨神经外科手术麻醉对体感诱发电位（SEP）的影响,以期为麻醉和手术处理提供依据。方法随机抽取我科17例全麻手术病人,分成颅内疾病手术组（A组）与脊柱、脊髓疾病手术组（B组）,于术前、麻醉（诱导完成）、术始、术中、术毕和术后6个时程连续监测SEP的潜伏期、波幅及波形并记录。结果麻醉后SEP潜伏期延长5.96%,波幅下降24.00%,未出现波形消失的情况。结论麻醉抑制SEP,表现为潜伏期延长和波幅下降,但未出现波形消失的情况。     

Laparoscopic Local Resection Based on Sentinel Node Evaluation for Early Gastric Cancer: A Preliminary Report

We previously reported that lymphatic mapping using isosulfan blue can be used to identify sentinel nodes (SNs). This study was undertaken to evaluate the feasibility of using the SN technique in treating early gastric cancer and to explore its usefulness for minimal invasive surgery. Twenty-three patients with early gastric cancer who underwent SN biopsy were retrospectively evaluated. Based on SN evaluation, individualized surgery was performed in five patients with T1N0M0 gastric cancer. When pathological examination of frozen sections revealed metastasis in SNs, we performed a standard D2 gastrectomy. Laparoscopic local resection was applied when the SN biopsy was negative. Our results showed that the success rate with SN biopsy in early gastric cancer was 100%, as were the accuracy, sensitivity, and specificity. All five patients with early gastric cancer had SNs negative for metastases both by frozen section and by postoperative pathology. Thus, all these patients underwent laparoscopic local resection without extended lymphadenectomy. We conclude that SN biopsy is a useful tool to individualize the operative procedure, and laparoscopic local resection can be safely performed using SN guidance in selected patients with early gastric cancer.     

血清高水平甲状旁腺激素-非透析慢性肾脏疾病患者的隐形杀手

维持性血液透析患者血清甲状旁腺激素(Parathyroid hormone,PTH)水平显著增高,PTH与患者心功能下降、营养状态恶化以及死亡率的增加密切相关.然而,临床实践发现,部分慢性肾脏疾病(Chronic kidney disease,CKD)3-4期、甚至CKD1期的患者血清PTH水平也增高,PTH对此类患者的影响如何,目前报道较为少见.本文结合文献就FTH对非透析CKD患者的心血管系统、骨代谢、营养状况及预后的影响作一综述.     

The role of neck dissection in the eradication of salivary carcinomas]

From 1955 to 1984, radical neck dissection (RND) had been done in 300 salivary carcinoma patients, 114 of which had regional lymph node metastasis, with a 38% metastatic rate. Respective 3, 5, 10, 15, 20 year survival rates were 76, 64, 47, 35, 35% in a 3 to 20 years follow-up study in 283 patients (94.33%). The following four points are concluded: 1. The metastatic rate is determined not only on tumor staging, but more to its typing (pathologic behaviour). 2. Elective RND gave a better prognosis than therapeutic and negative metastasis has a better survival chance than positive where the low level metastasis is the worst. 3. According to pathologic typing, Elective RND is indicated for undifferentiated adenocarcinoma, high malignant mucoepidermoid carcinoma, squamous cell carcinoma, adenocarcinoma and papillary cystic adenocarcinoma, therapeutic RND for malignant pleomorphic adenoma, acinic cell carcinoma and mucoepidermoid carcinoma. 4. Unilateral RND is indicated for all but sublingual and buccal tumors.     

Successful balloon pulmonary valvuloplasty for congenital valvular pulmonary stenosis in an octogenarian.

While balloon valvuloplasty has been widely used for the treatment of congenital valvular pulmonary stenosis (PS) in children and adults, its use in elderly patients is less common. An 80-year-old woman with congenital valvular PS received valvuloplasty with double-balloon technique. Right ventricle systolic pressure and pulmonary valve systolic pressure gradient decreased from 95 to 44 mm Hg and from 75 to 35 mm Hg, respectively. Follow-up Doppler echocardiography 2 months later showed further decrease in the transvalvular systolic pressure gradient to 29 mm Hg. The patient had symptomatic relief, and no major complication was noted. Balloon pulmonary valvuloplasty can be an effective treatment for elderly patients with congenital valvular PS.
