急性白血病血清LPO水平、全血Cu·Zn-SOD含量和GSH-Px活性的研究

采用硫代巴比妥酸（ＴＢＡ）法、放射免疫法和ＤＴＮＢ直接法对４５例急性白血病（ＡＬ）病人和３９例健康人血清ＬＰＯ水平、全血Ｃｕ·Ｚｎ－ＳＯＤ含量和ＧＳＨ－Ｐｘ活性进行了检测。提示在ＡＬ状态下，脂质过氧化作用增强，自由基水平增高，内源性抗氧化酶系统活力降低，清除自由基能力下降。动态观测ＡＬ病人三项指标的变化，对评价病情、估计预后具有一定的意义。

Analyses of mutation and loss of heterozygosity of coding sequences of the entire transforming growth factor beta type II receptor gene in sporadic human gastric cancer

Mutations in the transforming growth factor beta type II receptor (TGFbetaRII) gene have been detected in several human cancer types exhibiting microsatellite instability. Using intron primers previously reported for examination of the entire coding region of the TGFbetaRII gene, 29 sporadic gastric cancers were screened with non-radioactive single strand conformation polymorphism and subsequent DNA sequencing analysis. Mutations of the TGFbetaRII gene were detected in three out of 29 tumors (10%). Two cases showed deletions in a polyadenine tract in both alleles and was positively associated with replication error. One case had an insertion of GA dinucleotide sequence in one allele. Mutations of the TGFbetaRII gene were restricted to exon 3 and other coding regions were not affected. Loss of heterozygosity was detected by analyzing a polymorphic site in intron 2. Three out of nine (33%) informative cases, which were all of intestinal type and advanced cases, showed loss of heterozygosity but neither TGFbetaRII mutation nor replication error was found in these cases. Immunoreactivity of TGFbetaRII in tumor tissues was reduced to a different extent in the gastric cancer with genetically abnormal transforming growth factor. Although the numbers studied are small, homozygous (A)10 deletion or loss of heterozygosity of TGFbetaRII is involved in tumorigenesis and progression of at least some part of sporadic gastric cancer.      

血清α—L—岩藻糖苷酶诊断原发性肝细胞癌

目的通过观察血清α-L-岩藻糖昔酶（AFU）活性水平在原发性肝细胞癌（HCC）患者与肝硬化、肝炎及其他恶性肿瘤患者中的变化，评价其在HCC诊断中的价值。方法对44例HCC、18例肝硬化、36例肝炎和30例其他恶性肿瘤患者测定血清AFU活性水平。部分HCC患者曾经接受经导管肝动脉化疗栓塞术（TAE）。结果对照组平均血清AFU活性水平为150．39±35．34nKat／L，HCC组280．11±148．15nKat／L，肝硬化组、肝炎组及其他肿瘤组分别为248．89±68．82、196．67±79.61、168.93±49．89nKat／L。HCC组与对照组及肝炎组、其他肿瘤组之间存在明显差别，但与肝硬化组有部分重叠。结论AFU可作为肿瘤标志物用于诊断HCC与AFP及超声等联合参照应用。

目的探讨凝血酶原基因3’端非翻译区20210 G/A多态性与中国汉族人群肺血栓栓塞症(PTE)发生的相关性。方法采用病例-对照研究,病例组为经放射性核素肺通气/灌注显像和(或)螺旋CT肺动脉造影(CTPA)检查,并结合临床资料确诊的PTE患者101例;对照组为与PTE患者来自相同地区,性别、年龄相匹配的健康对照101例。应用碘化钾-氯仿-异丙醇法提取基因组。应用聚合酶链反应(PCR)、HindⅢ限制性内切酶片段长度多态性分析(RFLP)及聚丙烯酰胺凝胶电泳(PAGE)等方法检测凝血酶原G20210多态性。结果健康对照人群GⅡ20210A位点的基因频率符合Hardy-Weinberg平衡定律,PTE病例组及对照组GⅡ20210A位点均为野生型(GG)纯合子,GA、AA基因型频率为0,A等位基因频率为0。结论凝血酶原G20210A基因多态性与中国汉族人群PTE发生可能无关。     

中国居民代谢综合征与脑卒中的相关性研究

目的探讨中国居民代谢综合征与脑卒中的关系。方法数据来源于2002年中国居民营养与健康状况调查,选择15岁以上人群48633例,其中男性23080例,女性25553例。代谢综合征的定义参考中华医学会糖尿病分会2004年建议的标准。结果单因素logistic回归分析表明,代谢综合征与脑卒中呈正相关,OR值为5.998(95%CI4.799~7.496),多因素分析调整年龄、性别、6类地区、教育程度、中重度体力活动时间、吸烟、饮酒后代谢综合征与脑卒中仍具有统计学相关性,OR值为3.114(95%CI2.432~3.987)。代谢综合征的所有组分中,高血压与脑卒中的相关性最强,且随着代谢综合征组分在个体聚集越多(趋势性检验P<0.0001),患脑卒中的可能性越大。结论中国居民代谢综合征与脑卒中的患病有关。

研究脊柱结核的影像学诊断价值,并探讨各型脊柱结核的临床病理特点.对156例经临床及病理证实且影像学资料完整的脊柱结核进行回顾性分析,比较其X线(或CR)、CT及MRI的影像学特点及符合率.结果显示①X线(或CR)、CT及MRI对脊柱结核诊断符合率分别为90.5%、96.2%及99.5%.②X线(或CR)、CT及MRI对椎体骨质破坏、椎间隙狭窄的敏感性分别为74.5%、89.9%及96.87%.③对椎旁软组织肿块和腰大肌脓肿、附件破坏及骨性椎管受累的显示,CT优于X线(和CR)片;对早期病变的显示及脊髓受累情况,MRI优于X线(或CR)及CT,有显著差异性(P＜0.01).④对死骨及钙化的显示CT优于X线(或CR)及MRI.认为X线(或CR)检查为诊断脊柱结核的基本方法,但对早期病变的显示有限度;CT显示早期微小的骨质破坏、死骨、脓肿、钙化及脓肿对椎管脊髓压迫明显优于X线;MRI可清晰显示硬膜外脓肿及脊柱后突畸形对脊髓的压迫和脊髓变性情况,尤其是对早期病变的诊断,有较高的敏感性和特异性,但对死骨及钙化不敏感.     

联合激光周边虹膜切除术治疗原发性闭角型青光眼

目的：探讨联合激光周边虹膜切除术治疗原发性闭角型青光眼的临床疗效。

方法：收集2015-08/2017-10在我院就诊的原发性闭角型青光眼患者82例82眼,随机分为单纯激光组(33例,采用Nd：YAG激光周边虹膜切除术)和联合激光组(49例,采用532半导体激光联合Nd：YAG激光周边虹膜切除术)。记录两组患者眼压、激光能量、虹膜出血情况。

结果：单纯激光组患者术后眼压升高较联合激光组明显,术后1h,1d,1wk两组患者眼压差异明显(均P<0.01); 术后1mo两组患者眼压基本恢复至术前水平。单纯激光组患者术中1次透切成功率明显低于联合激光组(73% vs 100%,P<0.05),且术中使用Nd：YAG激光总能量明显高于联合激光组(40.16±13.43mJ vs 23.23±6.70mJ,P<0.05)。两组患者术中虹膜出血率无明显差异(33% vs 26%, P>0.05)。

结论：532半导体激光联合Nd：YAG激光行周边虹膜切除术1次透切率高,尤其对于无虹膜隐窝的患者,可明显降低激光操作难度,减少激光能量,减轻前房炎症反应。     

The disease characteristics of patients both with IgA nephropathy and diabetes mellitus

Objective To sum up and analyze the clinical and pathological characteristics in patients with both IgA nephropathy (IgAN) and diabetes mellitus. Methods A total of 500 patients were recruited, including 25 patients with both IgAN and diabetes mellitus, and 475 patients with IgAN only, who were diagnosed by renal-biopsy during Jan 2015 to Jan 2017 at the First Affiliated Hospital of Zhengzhou University. The clinical and pathological data were collected and analyzed using SPSS 22.0. Propensity Score Matching was used to match and select the patients in the both groups, and thereafter the depth of the basement membrane from the matched patients were compared using electron microscopy. The data of the patients whose follow-up time was ≥3 months were retrospectively collected, and Kaplan-Meier analysis was used to compare the difference of the prognosis. Results Compared to the patients with IgAN only, patients with both IgAN and diabetes mellitus were older [(46.36±13.49) years vs (34.00±13.80) years, P＜0.001], had higher level of serum triglyceride [2.06(1.52, 3.11) mmol/L vs 1.51(1.01, 2.25) mmol/L, P=0.012] and thicker basement membrane [(384.33±61.20) nm vs (346.72±52.65) nm, P=0.044]. The patients with both IgAN and diabetes mellitus were more prone to reach the composite endpoint [4/7(57.14%) vs 25/265(9.33%), P＜0.001] and had worse prognosis (Log-Rank test, P=0.004). Conclusions IgAN patients with diabetes mellitus have different clinical, pathological characteristics and prognosis from patients with IgAN alone. These patients need to be closely monitored and actively treated.
