Clinical observation of Qi deficiency syndrome in 72 patients with chronic obstructive pulmonary disease treated with Yiqi Mianyi Granule

Seventy-two patients of chronic obstructive pulmonary disease (COPD) of Qi deficiency syndrome with abnormal immune indices were treated with Yiqi Mianyi Granule (YQMYG) and the efficacy was compared with that of 30 cases treated with Zhenqi fuzheng Granule (ZQFZG) for control. Results showed that the markedly effective rate of symptomatic improvement of Qi deficiency in YQMYG group was 65.3%, the total effective rate 93.1%. 88.6% of the immune indices lower than normal were corrected and 43. 7% of them were normalized, while for indices that were higher than normal the rate were 78.2% and 52.9% respectively. These results suggested that YQMYG could improve symptom of Qi Deficiency markedly, strengthen cellular immunity and regulate immune dysfunction. Its therapeutic efficacy was obviously superior to ZQFZG (P<0.Q5).

Results of speech perception and speech production training for three prelingually deaf patients using a multiple-electrode cochlear implant.

Five studies were conducted to measure changes in the perception and production of selected speech targets, with training, in three prelingually deaf patients. The two adults and one adolescent were implanted with the Cochlear (Nucleus) multiple-electrode prosthesis. The studies were perception and production of nasal consonants; perception of syllable-final consonants; perception and production of alveolar consonants; auditory-visual perception of alveolar consonants; and perception and production of vowels. Perceptual data were collected in the audition (implant)-alone condition, except for the auditory-visual perception of alveolar consonants where the audition-alone, vision-alone, and auditory-visual conditions were used. Speech perception data in the audition-alone condition were also collected from four postlingually deaf adult implant patients, without training, to indicate differences between the two classes of patients. The three prelingually deaf patients generally showed some improvements in speech production. In perception, improvements were recorded only for individual patients in some studies. The performance of the adolescent was better than that of the two adults in all cases. The perceptual performance of the postlingually deaf patients was superior to that of the prelingually deaf patients in all cases.     

白细胞介素—2新的功能位点及其中枢镇痛作用

白细胞介素－２（ＩＬ－２）不仅是重要的免疫调节因子，而且还具有重要的中枢调节作用。本实验以钾离子透入引起大鼠甩尾反应为指标，发现侧脑室注射ＩＬ—２能显著提高动物痛阈，并能被纳洛酮所阻断，表示ＩＬ－２的中枢镇痛作用可能与阿片受体有关。利用基因定位突变技术获得的无免疫活性ＩＬ－２实查体仍具有中枢镇痛作用，表明ＩＬ—２分子上发挥镇痛和免疫调节作用的功能位点是相互独立的。纳洛酮能够阻断ＩＬ—２的中枢镇痛作用，而不能影响ＩＬ—２增殖ＣＴＬＬ－２细胞的作用，提示ＩＬ－２发挥镇痛和免疫调节作用可能通过不同的受体途径。ＩＬ－２分子中第４５位Ｔｙｒ残基突变为Ｖａｌ后，虽仍保留了免疫活性，但丧失了镇痛功能，表示４５位Ｔｙｒ残基是ＩＬ—２发挥中枢镇痛功能的关键残基之一。我们推测ＩＬ—２的镇痛功能位点可能在ＩＬ—２分子中第４５位Ｔｙｒ残基附近区域。     

延颈髓交界处髓内肿瘤的诊断与显微手术治疗

报道显微手术治疗10例延颈髓交界处髓内肿瘤(ITCJ),肿瘤全切除6例,次全切除4例,无手术死亡,70％病例术后好转。ITCJ可分为颈延型和延颈型两大类型。MRI是诊断本病的主要方法,并且具有指导手术的重要意义。结果也表明,显微手术方法和术后呼吸功能监护很有必要。

HCVRNA阳性的丙型肝炎诊断和治疗探讨

HCVRNA阳性的丙型肝炎46例，均经临床和／或组织学确诊。治疗组24例用IFNa－nl或a－2b3×106IU，隔日一次；对照组22例用一般护肝药物。HCVRNA12周转阴率治疗组为83．3％，对照组为9．0％（P＜0．001）。ALT和AST复常率治疗组也优于对照组（P＜0．05）。随访观察满48周者治疗组15例中HCVRNA持续转阴11例（73．3％）．对照组5例均持续阳性。治疗组中5例做了Ⅰ～Ⅲ型HCV基因分型，结果均为Ⅱ型。同时对急、慢性丙型肝炎的发病过程和病理诊断作了讨论。     

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.
