偏心圆剥离法在隆乳术中的应用

以往以乳头为圆心的同心圆剥离法常形成假体的移位，使假体的体表轮廓与前方的自然乳房分离，产生“双重乳房”现象。在研究了女性不同体位下不同的乳房形态及总结了以前的经验后，提出了偏心圆剥离的概念。偏心圆手术设计方法：以乳头为圆心，按其内侧、下侧为直径３／５的比例，以外侧、上侧为直径２／５的比例，形成一偏心圆的剥离范围。偏心圆的直径因考虑到假体的不同形态、大小及底面直径，以经中心假体纵截面的周长的１／２再放大２ｃｍ，作为剥离范围的直径。自１９９１年１０月以来已应用了１７６例，无一术后移位现象，也没有固较多地剥离胸大肌内、下侧止点纤维而影响上肢活动。自然乳房并不是静态的圆锥形或半球形，它具有伸缩的组织学特点，又有随体位变动而变化的特点。用偏心圆法剥离，可使置入的假体与前方的自然乳房融为一体，消除“双重乳房”现象，而成为“真实”的乳房。同时也应积极寻找一种与身体组织相容性好的，弹性、比重与女性乳腺较为一致的，假体容量相对恒定的生物性材料。这样隆乳术才可以更广泛地开展。     

EPF单克隆抗体杂交瘤细胞株的建立

本文用纯化的早孕因子免疫ＢＡＬＢ／Ｃ小鼠，通过鼠－鼠杂交瘤技术，成功地建立了２株分泌ＥＰＦ单克隆抗体的杂交瘤细胞。经检测，它们所分泌的抗体亚类均为ＩｇＧ１，毁交瘤染色体数目１００－１０６条，ＥＩＳＡ检测诱生腹水抗体效价为１：１．２８＊１０＾５，连续培养生物学性状稳定。抗ＥＰＦ抗原的单克隆抗体的建立，为深入研究ＥＰＦ的生物学性质、特征提供了有力的工具。     

Acute pericarditis as the initial manifestation in Still's disease in an adult

Almost 90% of primary acute pericarditis are idiopathic. Between specifics forms, a very low percentage of cases are due to chronic rheumatic diseases. A case of adult Still's disease (juvenile chronic rheumatoid arthritis) with acute pericarditis being the first clinical manifestation (besides fever and general syndrome) is presented. Therapy with oral prednisone was rapidly effective, and pericardial effusion resolved after 3 weeks of treatment, as echocardiography showed.     

血管紧张素Ⅱ受体—1在清醒大鼠血压波动性调节中的作用

目的：探讨血管紧张素Ⅱ受体－１（ＡＴ１受体）在清醒ＷＫＹ大鼠和自发性高血压大鼠（ＳＨＲ）血压波动性（ＢＰＶ）调节的作用。方法：应用计算机化清醒自由活动大鼠血流动力学监测技术，分别观察了：（１）静注新型非肽类ＡＴ１受体拮抗剂Ｌｏｓａｒｔａｎ（Ｌｏｓ）；９２）静注神经节阻断剂氯异朵铵；（３）静注Ｃｈｌｏｒ和Ｌｏｓ；（４）静滴血管紧张素Ⅱ（ＡＮＧⅡ）及静注Ｃｈｌｏｒ后静滴ＡＮＧⅡ对ＷＫＹ大鼠和ＳＨＲ血压     

Prognostic significance of cytochemical analysis of leukemic M2 blasts

Cytochemical analysis of leukemic blasts from 46 patients with acute myeloblastic M2 leukemia (according to the FAB classification) was performed before and after cytostatic therapy, and compared with findings obtained in 20 age- and sex-matched control subjects. Cytochemical findings for myeloperoxidase (MPO), Sudan black B, acid phosphatase and alpha-naphthyl-acetate esterase (ANAE) were related to the achievement of the first complete remission (CR),i.e. data were compared after the patients had been divided into CR and non-CR groups. The analysis clearly showed that a high proportion of myeloperoxidase- and, to a lesser extent, Sudan black B-positive blasts before treatment may have constituted a significantly unfavourable prognostic factor.     

北京、广州、上海城市居民营养知识、态度、行为的调查

对北京、广州和上海三大城市随机抽取的９６５名年龄在２０～５０岁的城市居民进行有关营养知识、态度和行为（Ｋ－Ａ－Ｐ）的调查。结果显示，三地区调查对象的营养知识水平不高。营养知识的得分与其自身受教育程度有相关性（ｒ＝０．３０１１，Ｐ＜０．０１）。年龄在３５岁以上的对象，营养知识的得分高于年轻人；三地区调查对象对营养知识的获取，合理的膳食模式，卫生的饮食习惯均持有积极、肯定的态度。食物消费频度调查结果表明，米／面、肉／禽、蔬菜、水果、奶及奶制品的消费量较高。此外，８９．５％，７８．８％和４７．８％的调查对象分别选择报纸、电视、广播作为其主要营养信息来源。本次调查为将来的营养宣教的内容和方法提供依据。     

Coronary permeability and left ventricular function following thrombolytic therapy

We study 40 patients, 55 +/- 7 years old with acute myocardial infarction treated early by thrombolytic therapy (20 STK and 20 rt-PA). All patients were angiographically studied in the following conditions: 1) baseline, before initiating therapy. 2) Three hours after treatment. 3) Twenty four hours later. 4) Before discharge. The infarct related artery was patent 24 hours after treatment in 31 patients (78%); five of them were patent before treatment, and we observed an early reperfusion in 20 patients (57%) and late reperfusion in 6 patients (17%). The number of patients with angiographic evidence of intraluminal thrombus decreased progressively through conditions while the grade TIMI of coronary perfusion increased in the absence of reocclusion. Final regional wall motion of infarct related myocardial zones and their degree of recovery were significantly higher in recanalized patients, as compared with non-reperfused patients. Similarly, left ventricular functional recovery was higher in patients with antegrade of collateral flow to the infarct area, as compared with totally occluded patients.     

Treatment of singultus following craniocerebral injury★ Intranasal cavity drip infusion versus intramuscular injection of aminazine

BACKGROUND: Craniocerebral injury always accompanies with singultus, while frequent singultus may cause increased intracranial pressure. Simultaneously, respiratory alkalosis and cerebral hypoxia induced by respiratory disorder may aggravate craniocerebral injury. OBJECTIVE: To observe the therapeutic effects of intranasal cavity drip infusion of aminazine and intramuscular injection on singultus following craniocerebral injury. DESIGN: Contrast observation. SETTING: Department of Neurosurgery, Xi'an Aerospace General Hospital. PARTICIPANTS: A total of 102 patients with singultus following craniocerebral injury were selected from the Department of Neurosurgery, Xi'an Aerospace General Hospital from June 2001 to June 2006. Patients with craniocerebral injury were diagnosed with CT examination and randomly divided into nasal cavity medication group (n =62) and intramuscular injection group (n =40). There were 44 males and 18 females in the nasal cavity medication group and their mean age was (33±4) years; while, there were 26 males and 14 females in the intramuscular injection group and their mean age was (29±4) years. All patients and their relatives provided the confirmed consent. METHODS: Patients in the nasal cavity medication group were slowly dripped aminazine solution into bilateral nasal cavity with the dosage of 12.5 mg (0.5 mL). Patients who had no obvious effect or had mild improvement received the treatment once every 6 hours. The treatment was stopped if symptoms were also observed after the fifth medication. In addition, patients in the intramuscular injection group received intramuscular injection of 50 mg aminazine. Patients who had no obvious effect or had mild improvement received the treatment once every 6 hours. The treatment was changed if symptoms were also observed after the fifth medication. MAIN OUTCOME MEASURES: Therapeutic effects of different medications in the two groups. RESULTS: All 102 patients were involved in the final analysis. Effective rate in the nasal cavity medication group was higher than that in the intramuscular injection group, and there was significant difference (χ2= 11.882, P < 0.01). At 6 hours after onset of singultus, effective rate in the nasal cavity medication group was higher than that in the intramuscular injection group, and there was significant difference (χ2 =8.188, P < 0.01). CONCLUSION: Therapeutic effects of intranasal cavity drip infusion of aminazine on singultus following craniocerebral injury are superior to those of intramuscular injection.
