    Acupuncture can induce changes in the brain. However, the majority of studies to date have focused on a single acupoint at a time. In the present study, we observed activity changes in the brains of healthy volunteers before and after acupuncture atTaichong (LR3) andTaixi (KI3) using resting-state functional magnetic resonance imaging. Fifteen healthy volunteers underwent resting-state functional magnetic resonance imaging of the brain 15 minutes before acupuncture, then received acupuncture atTaichong andTaixi using the nail-pressing needle insertion method, after which the needle was retained in place for 30 minutes. Fifteen minutes after withdrawal of the needle, the volunteers underwent a further session of resting-state functional magnetic res-onance imaging, which revealed that the amplitude of low-frequency lfuctuation, a measure of spontaneous neuronal activity, increased mainly in the cerebral occipital lobe and middle occipital gyrus (Brodmann area 18/19), inferior occipital gyrus (Brodmann area 18) and cuneus (Brodmann area 18), but decreased mainly in the gyrus rectus of the frontal lobe (Brodmann area 11), inferi-or frontal gyrus (Brodmann area 44) and the center of the posterior lobe of the cerebellum. The present ifndings indicate that acupuncture atTaichong andTaixi speciifcally promote blood lfow and activation in the brain areas related to vision, emotion and cognition, and inhibit brain areas related to emotion, attention, phonological and semantic processing, and memory.

    Objective: hTe results of a previous study showed that a clear dysregulation was evident in the global gene expression of the BCL11A-suppressed B-lymphoma cells. In this study, the bone morphogenetic protein receptor, type II (BMPR2), E1A binding protein p300 (EP300), transforming growth factor-β2 (TGFβ2), and tumor necrosis factor, and alpha-induced protein 3 (TNFAIP3) gene expression patterns in B-cell malignancies were studied.
    Methods:The relative expression levels ofBMPR2,EP300,TGFβ2, andTNFAIP3 mRNA in B-lymphoma cell lines, myeloid cell lines, as well as in cells from healthy volunteers, were determined by real-time quantitative reverse transcript-polymerase chain reaction (qRT-PCR) with SYBR Green Dye. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was used as reference.
    Results:hTe expression level ofTGFβ2 mRNA in B-lymphoma cell lines was signiifcantly higher than those in the cells from the healthy control (P<0.05). However, the expression level ofTNFAIP3 mRNA in B-malignant cells was signiifcantly lower than that of the healthy control (P<0.05). hTe expression levels ofBMPR2 andEP300 mRNA showed no signiifcant difference between B-malignant cell lines and the healthy group (P>0.05). In B-lymphoma cell lines, correlation analyses revealed that the expression ofBMPR2 andTNFAIP3 (r=0.882,P=0.04) had signiifcant positive relation. hTe expression levels ofBMPR2,EP300, andTNFAIP3 mRNA in cell lines from myeloid leukemia were significantly lower than those in the cells from the healthy control (P<0.05). hTe expression levels ofTGFβ2 mRNA showed no signiifcant difference between myeloid leukemia cell lines and the healthy control or B-malignant cell lines (P>0.05). hTe expression levels of BMPR2,EP300, andTNFAIP3 mRNA in B-lymphoma cells were signiifcantly higher than those of the myeloid leukemia cells (P<0.05).
    Conclusion:Different expression patterns ofBMPR2,EP300,TGFβ2, andTNFAIP3 genes in B-lymphoma cells exist.

  • 帕金森患者平衡障碍的定量评定(论著摘要)

    作者:

    Background: Patients with Parkinson' s desease(PD) often suffered from postural and balance dysfunction. To explore the level of postural and balance dysfunction of PD patients, postural and balance fuction were also evaluated quantitiatively in 100 PD patients.Objective: To study objectively and quantitatively the static postural control of healthy volunteers and patients with Parkinson, s disease (PD).Design: To test volunteers and patients with PD with computerized balance assessment instrument, analyzed and compared the static posturography.Unit(Adress): Department of Neurology, Beijing Hospital, Beijing 100730,china Subject: There were one hundred patients with PD, 44 females and 56 males,aged between 50 ~ 80 years(mean age 65 + 6years), one hundred volunteers, 48 females and 52 males, aged between 50 ~ 78 years (mean age 66 + 7years).

  • 泊沙康唑新型固体口服制剂:研究健康受试者中单剂和多剂剂量递增给药的药动学特性和安全性的随机临床试验

    作者:胡佳丽(摘译);张菁(审校)

    目的:泊沙康唑是一种有效治疗和预防真菌感染的三唑类广谱抗真菌药物。市售的口服混悬液需与食物同服以使药物达到大吸收。现已研发出一种生物利用度高且不需同时进食的新型固体口服片剂。本研究旨在评价健康受试者中该新制剂单剂和多剂剂量递增给药后的药动学特性、安全性以及耐受性。

    Objective: To study the changes and clinical significance of arginine vasopressin (AVP) and angiotensin II (AT-II) in patients with acute moderate and severe cerebral injury.   Methods: The early plasma concentration was checked by radioimmunoassay in 47 cases of acute moderate and severe cerebral injury, 30 cases of non-cerebral injury and 30 healthy volunteers.   Results: The early plasma concentrations of AVP (50.23 ng/L±15.31 ng/L) and AT-II (248.18 ng/L±82.47 ng/L) in cerebral injury group were higher than those in non-cerebral injury group (AVP for 30.91 ng/L±11.48 ng/L and AT-II for 120.67 ng/L±42.49 ng/L, P<0.01). The early plasma concentrations of AVP and AT-II in cerebral injury group were also obviously higher than those of the volunteers (AVP for 5.16 ng/L±4.23 ng/L and AT-II for 43.11 ng/L±16.39 ng/L, P<0.001). At the same time, the early plasma level of AVP (58.90 ng/L±18.12 ng/L) and AT-II (292.13 ng/L±101.17 ng/L) was higher in severe cerebral injured patients than moderate cerebral injured ones (AVP for 36.68 ng/L±12.16 ng/L and AT-II for 201.42 ng/L±66.10 ng/L, P<0.01). The early level of AVP and AT-II was negatively related to the GCS scales in acute cerebral injury. The early plasma concentrations of AVP (45.98 ng/L±13.48 ng/L) and AT-II (263.28 ng/L±80.23 ng/L) were lower in epidural hematoma group than those of subdural hematoma and cerebral injury group (AVP for 64.12 ng/L±15.56 ng/L and AT-II for 319.82 ng/L±108.11 ng/L, P<0.01).   Conclusions:  AVP and AT-II may play an important role in pathophysiologic process in the secondary cerebral injury. The more severe the cerebral injury is, the higher the early level of AVP and AT-II will be. The early plasma level of AVP and AT-II may be one of the severity indexes of cerebral injury.
