Mendelian randomization suggests a potential causal effect of eosinophil count on influenza vaccination responsiveness

Currently, the clinical factors affecting immune responses to influenza vaccines have not been systematically explored. The mechanism of low responsiveness to influenza vaccination (LRIV) is complicated and not thoroughly elucidated. Thus, we integrate our in-house genome-wide association studies (GWAS) analysis result of LRIV (N = 111, Ncase [Low Responders] = 34, Ncontrol [Responders] = 77) with the GWAS summary of 10 blood-based biomarkers (sample size ranging from 62 076−108 794) deposited in BioBank Japan (BBJ) to comprehensively explore the shared genetics between LRIV and blood-based biomarkers to investigate the causal relationships between blood-based biomarkers and LRIV by Mendelian randomization (MR). The applications of four MR approaches (inverse-variance-weighted [IVW], weighted median, weighted mode, and generalized summary-data-based MR [GSMR]) suggested that the genetically instrumented LRIV was associated with decreased eosinophil count (β = −5.517 to −4.422, p = 0.004−0.039). Finally, we conclude that the low level of eosinophil count is a suggestive risk factor for LRIV.

当归补血汤对细胞免疫调节作用及超微结构的影响

本实验采用环磷酰胺(CY)制造免疫功能低下小鼠的动物模型,研究当归补血汤组成药物的不同比例配伍,对机体免疫功能调节作用的影响。实验过程中将当归、黄芪分别配制成1∶1(A方)、1∶5(B方)、5∶1(C方)的不同比例中药方剂,对小鼠施以灌胃,并设对照组,以WBC总数、T淋巴细胞转化率及胸腺细胞超微结构变化作为检测指标。结果表明:三组不同比例配伍的方剂,对小鼠机体免疫功能均有调节作用。三组之间比较,提高WBC总数以A方效果最明显;三个方剂均有促进淋巴细胞转化的作用,但转化率三者之间无明显差异;保护胸腺细胞作用以B方效果最好。应用:当归补血汤对机体免疫功能有明显调节作用,但不同比例配伍,对机体免疫功能调节作用各有所侧重     

Cohort study of the total leukocyte count and periodontal disease among company employees

There have been few epidemiological studies of the relationship between the leukocyte count and dental disease. In the present study, therefore, we investigated the relationship between oral health indicated by the Community Periodontal Index of Treatment Needs (CPITN) and the total leukocyte count in the cohort study. The 1,035 subjects were male factory workers employed at a chemical factory in Osaka, Japan. Their oral conditions were recorded as the CPITN score. The relationship between the total leukocyte count and the oral condition of the subjects classified according to their smoking habits was investigated over a 5-year period. Among the current smokers, the total leukocyte count was highest each year for the group with CPITN level 4, followed by those with CPITN levels 3 and 2 in descending order, showing that the total leukocyte count was reduced as the periodontal diseases ameliorated. Among the nonsmokers, the total leukocyte count was high every year in the group with CPITN levels 4 or 3 compared to that of the group with CPITN level 2. The fluctuations of the total leukocyte count in current smokers and nonsmokers whose CPITN score increase or decreased in five years was investigated. There were no significant differences among the all groups.     

ITP患者脾动脉栓塞前后血小板的检测及其临床意义

应用自动血细胞计数仪检测ＩＴＰ患者脾动脉栓塞前后不同时期血小板的变化。结果栓塞后患者血小板计数（ＰＬＴ）和平均血小板体积（ＭＰＶ）的变化呈负相关,但ＰＬＴ恢复正常后,ＭＰＶ仍高于正常。提示脾动脉栓塞后血小板计数增高的机理不同于激素治疗。

槲皮素对培养人视网膜色素上皮细胞增生及DNA合成的影响

目的研究槲皮素(quercetin, QUE)对培养人视网膜色素上皮(retinal pigment epithelium, RPE)细胞增生和DNA合成以及对表皮生长因子(epidermal growth factor, EGF)促RPE细胞增生和DNA合成作用的影响。方法用细胞计数和3H-胸腺嘧啶核苷(3H-thymidine, 3H-TdR)掺入方法,观察不同浓度(200、100、50、1μmol/L)的QUE和最大浓度的QUE(200μmol/L)在不同作用时间（24-168小时）,分别单独或与EGF共同作用时,对RPE细胞增生及DNA合成的影响,排除着色的死细胞,用活细胞计数法判断药物的细胞毒性作用。结果QUE 200μmol/L具有最强的抑制效应,48小时时抑制效应已明显出现,96小时时抑制达到高峰。与QUE单独作用相比,QUE对EGF的促RPE细胞增生效应能产生更强的抑制。QUE无细胞毒性作用,各实验组细胞活力均在85.00%以上。结论QUE以剂量依赖和时间依赖的方式抑制RPE细胞的增生,尤其是由EGF刺激的增生,并且对培养的RPE细胞无细胞毒作用。(中华眼底病杂志,1999,15:27-29)     

Early splenectomy and polychemotherapy versus polychemotherapy alone in chronic myeloid leukemia

The effect of early splenectomy and of polychemotherapy with hydroxyurea, busulfan, and alternate bimonthly courses of arabinosyl cytosine and vincristine plus prednisone, was evaluated in 139 previously untreated patients with chronic myeloid leukemia (CML), consecutively admitted to 18 hospitals from March 1973 to October 1974. Fifty-six patients were splenectomized and 83 patients were not splenectomized. Splenectomy did not influence the duration of chronic and blastic phase, and did not prolong survival. The prognosis of high risk patients was not improved. During the chronic phase, high platelet counts were more frequent in splenectomy group, and five patients developed thrombotic or thromboembolic complications, 5 to 19 months after the operation. The median survival of the whole group was 50 months, with 32 of 139 patients (actuarial proportion 30%) remaining alive 72 months after diagnosis, but the slope of the survival curve was similar to that of historical controls. The results of this trial suggests that new strategies should be developed for the therapy of CML.
