Determination of antigen-dependent activity of human lung cancer transfer factor by H3-leucine leucine leukocyte adherence inhibition assay]

This report is to demonstrate the antigen-dependent activity of human lung cancer transfer factor (Sp-TF). Sp-TFM was prepared from spleen of mice immunized with the human lung cancer cell line A549. [3H]-leu leukocyte adherence inhibition assay ([3H]-leu-LAI) was modified to identify activity of Sp-TFM. Leukocytes obtained from non-immunized mice were divided into eight groups as follows: 1. Control without TF or antigen; 2. Sp-TFM and antigen of cell line A549 (A549 Ag); 3. Sp-TFM alone; 4. Sp-TFM and ascitic tumor cell H22 antigen of mice (H22Ag); 5. Sp-TFM and antigen of human gastric cancer cell (HGCCAg); 6. Sp-TFM and antigen of human normal lung tissue (NLTAg); 7. Nor special TF of mice (N-TFM) and A549Ag; 8. A549Ag alone. When normal leukocytes were incubated with Sp-TFM and A549 antigen, the leukocytes adherence inhibition index (LAII) was significantly higher than those of the other groups. The different LAII of Sp-TFM to A549Ag and other experimental groups were highly significant (P less than 0.001). The results demonstrated that Sp-TFM could transfer specific cell mediated immunity to non-immune leukocytes. The TF prepared from spleen of goat immunized with antigen from lung cancer of patients (Sp-TFG) showed antigen specific activity as well as Sp-TFM.     

人脑胶质瘤逃避免疫监视机制的研究

为研究胶质瘤逃避免疫监视的机制，检测了胶质瘤体外细胞系培养上清（SN）抗PHA－P刺激正常人及胶质瘤患者外周血淋巴细胞增殖的作用。证实了胶质瘤可自分泌免疫抑制因子。经抗TGFβ2单抗中和SN试验，TGFβ2免疫组化染色及Northern杂交进一步表明该因子主要成分为TGFβ2并对胶质瘤患者血浆皮质醇，生长激素及儿茶酚胺含量及细胞免疫功能进行检测，发现血浆去甲肾上腺素显著降低，其水平与CD8亚群％呈负相关，与CD4／CD8比值及淋巴细胞增殖率呈正相关。初步提示存在胶质瘤的情况下，神经－免疫调控紊乱，可能起着抑制性调节作用。     

Ancillary Community Pharmacy Services Provided to Older People in A Largely Rural and Ethnically Diverse Region: A Survey of Consumers in West Texas

Little is known about the quality of pharmacy services provided to the rural elderly population. This exploratory study examines rural/urban and ethnic differences in perceived access to ancillary pharmacy services among elderly people. Two telephone surveys were conducted using directory listings in West Texas to generate a longitudinal sample. Persons aged 65 years and older who were not cognitively impaired were asked to complete the survey. The number of participants in both rounds of the survey was 3,689. Seven ancillary pharmacy services were examined: delivery of medications, medication counseling, written medication information, blood pressure monitoring, blood glucose monitoring, osteoporosis screening, and immunization. The sample was stratified by county of residence (urban, rural, or frontier) and racial/ethnic background. Chi-square tests were performed to detect rural/urban and racial/ethnic differences in access to the seven ancillary services. The association between proficiency in English and access to the services was also examined. Rural residents were more likely than urban residents to report that their pharmacies provide delivery of medications, medication counseling, and immunization services, but they were less likely than their urban counterparts to report that their pharmacies provide blood pressure monitoring. Access to ancillary pharmacy services was reported as poorer by older Hispanic people compared with non-Hispanics. Deficiency in English was significantly related to inequality in reported access to ancillary pharmacy services. It is essential to consider the special needs of rural and Hispanic elderly people to ensure equitable access to ancillary pharmacy services.     

Smooth muscle relaxant effect of dehydroindicolactone

Dehydroindicolactone, a novel linear furanocoumarin with an 8-substituted side chain carrying a 5-member ring lactone, showed spasmolytic activity in a number of smooth muscle preparations. The spasmolytic activity seems to lie in its ability to block the dihydropyridine-sensitive calcium channel.     

动态监测胃黏膜内pH值对胆源性胰腺炎外科治疗的价值

目的探讨胃黏膜内pH值对胆源性胰腺炎病情预后评估及在决定手术冶疗中应用的价值。方法对确诊的146例胆源性胰腺炎患者经鼻插入胃黏膜二氧化碳张力计（TRIP-NGS导管）测定胃黏膜内pH值，每隔12小时测定一次，并进行APACHEⅡ评分，将2组数据与外科治疗进行相关分析。结果①pH值变化反映胆源性胰腺炎病情发展变化，与器官衰竭数呈负相关；②外科干预治疗与内科治疗比较差异有统计学意义（P〈0．05）；③pHI〉7．25与pH〈7．25患者开腹手术病死率和细菌培养阳性率比较差异有统计学意义（P〈0．05）。结论pH值对胆源性胰腺炎外科治疗有指导意义。外科处理原则是：①胆道无梗阻，以内科保守治疗为主；②伴胆道梗阻，先行经内镜十二指肠乳头括约肌切开术、经内镜鼻胆管引流术、B超导引引流、腹腔灌洗等，如胆道引流不畅或pH值持续下降，则开腹手术。

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     

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.
