加减化裁随证治之——何任治疗癌症学术经验探究(下)

癌症为深危重疾,对于绝大部分癌症患者,临床普遍采用手术、中医、化疗、放疗、生物等综合方法进行治疗。由于癌症的种类、所处阶段、先前采用的治疗方法以及病人体质等等的不同,求诊时病人的证     

50例正常生育力男子精液和血液激素的一年动态观察

作者对南京市50名正常男子,每月1次、连续12个月测定了精液常规、某些精液生化和血清激素水平。结果表明:精子密度每次之间波动范围较大,冬季数值比夏季显著为高(P<0.01)。其它指标包括正常形态精子、活动精子、前向运动级别、精液果糖、硷性磷酸酶、酸性磷酸酶及血清,FSH LH T 则变动不显著。精液常规中除精子密度和各参数关系不明显外,所有其它参数之间呈正相关;但精液常规、精液生化和血清激素三者互不相关。从本组研究结果,作者提出了南京市正常男子这些指标的参考正常值。     

鸡和大鼠小脑发育的比较观察

观察发育阶段不同的鸡和大鼠的小脑标本外形,并在光学显微镜和电子显微镜下观察了结构。鸡卵在孵育的第6天,小脑原基出现。第15天小脑皮质形成,普肯野氏细胞(普氏细胞)排成一层。新生鸡小脑皮质发育近成年状态,普氏细胞发育基本完成。大鼠在生后第5天小脑皮质形成,第20天发育成熟。在生后第5天普氏细胞排成一层,第20天接近成熟状态,此时在电子显微镜下显示为粗面内质网和多聚核蛋白体区域性集中分布。鸡小脑比大鼠小脑发育早,这是种属差异。     

可切除原发性十二指肠恶性肿瘤X线征象分析

目的 :对可切除的原发性十二指肠恶性肿瘤X线征象进行分析。方法 :对 2 6例原发性十二指肠恶性肿瘤胃肠道造影及CT征象进行了回顾性对比分析总结。结果 :全部病例均经手术病理证实 ,其中腺癌 2 2例 ,平滑肌肉瘤 3例 ,非何杰金氏淋巴瘤 1例。描述包括肿瘤的部位 ,造影X线表现 (黏膜破坏 ,充盈缺损及龛影 ,管腔不规则狭窄 ,肠腔外改变等 )及CT表现 (肠壁增厚肠腔狭窄 ,局部肿块 ,梗阻性改变及转移 )。不能手术切除的影像学征象为 :肿瘤直径大于 6cm ;腹腔、系膜淋巴结成团肿大 ;腔静脉、肠系膜动静脉等重要血管管径被包绕大于 2 / 3时。结论 :CT与X线造影对肿瘤的位置、大小、形态 ,肿瘤的继发征象的术前评价 ,能够提供能否手术切除的重要依据。     

A novel DRB1*09 allelic sequence in the Jing ethnic minority of China.

A new DRB1 allele, DRB1*0902, has been identified in an individual of the Jing ethnic minority. Its sequence was confirmed by sequencing of PCR products and clones. This allele differed by three nucleotides from DRB1*09012 at positions 157, 161 and 166, and resulted in amino acid motif substitution from VAES to DAEY.     

高效液相色谱法测定右旋儿茶素血浆浓度及药代动力学参数

本文建立了体液中右旋儿茶素的RP-HPLC测定方法。采用C_(18)键合相硅胶为填料的固相提取柱进行样品预处理,右旋儿茶素的提取回收率为79.8%.应用二极管阵列检测器对色谱峰纯度进行鉴定。该法精密度好,方法回收率近100%,日内、日间的变异系数为2.4～5.6%,血浓69.6～1160 ng/ml范围内呈线性关系,r=0.9993。家兔静注右旋儿茶素18mg/kg,其药代动力学过程符合二室模型,分布相半衰期为0.129 h,消除相半衰期为1.19h。     

The indication of surgical treatment of cerebellar hemorrhage]

61 patients with cerebellar hemorrhage were studied. The age at onset ranged from 15 to 84 years with a mean of 57.4 years. 49 cases were treated conservatively and 12 surgically and the mortality rates of the two groups were 32.5% and 25% respectively. Based on this study, it is suggested that the clinical and CT indications of surgical treatment of hematoma are as follows; Severe disturbance of consciousness; Bilateral eyeball fixation; Volume of hematoma over 10 ml; Size of hematoma over 4 cm in diameter; Marked acute obstructive hydrocephalus; Compression of cisterna ambieus and quadrigeminus.     

缺锌对大鼠力竭性游泳前后睾酮和锌水平变化的影响

本实验动态观察了缺锌和缺锌后补锌对大鼠力竭性游泳前后辜丸和血清睾酮、锌水平以及游泳能力的影响。结果显示：缺锌造成大鼠游泳能力大大降低，补锌后明显增加。不论安静时还是力竭性游泳后１２小时内，缺锌大鼠的血清和辜丸锌含量均显著低于对照和补锌大鼠。与对照和补锌大鼠相比，缺锌大鼠的血清和睾丸酮含量，安静时均较低，力竭性游泳后也呈现不同程度的降低。缺锌还造成大鼠辜丸重量的明显下降。结果表明，锌营养不良将损害运动能力。     

锰超氧化物岐化酶模型配合物的研究

为探索天然超氧化物岐化酶（ＳＯＤ）岐化超氧离子的机理，及用于临床的可能性，我们合成了乳酸、柠檬酸和酒石酸的锰（Ⅱ）配合物作为Ｍｎ－ＳＯＤ的模拟物，用光照法测定了它们的活性，得到了有意义的结果：锰配合物作为Ｍｎ－ＳＯＤ的模拟物，有肯定的活性，其中以乳酸锰配合物活性最高。     

Detection of subclinical ascorbate deficiency in early Parkinson''s disease

From mid-October 1989 to mid-July 1990 all newly admitted residents to Bury Local Authority Residential Homes were comprehensively medically screened. In a series of 100 residents eight had early Parkinson's disease (six of them hitherto undiagnosed). Seven showed evidence of Vitamin C deficiency. Of the seven showing evidence of deficiency, four suffered from early Parkinson's disease. Of the 93 without evidence of Vitamin C deficiency only four had Parkinson's disease. This indicates a significantly higher prevalence of Parkinson's disease in the group with Vitamin C deficiency (P less than 0.001 using Fisher's exact).
