In this review, we outline the major neural plasticity mechanisms that have been identiifed in the adult central nervous system (CNS), and offer a perspective on how they regulate CNS function. In particular we examine how myelin plasticity can operate alongside neurogenesis and synaptic plasticity to inlfuence information processing and transfer in the mature CNS.

BACKGROUND:Subjective discomforts in a preclinical range are often due to imbalanced autonomic nervous system activity, which is a focus of craniosacral therapy. OBJECTIVE:The aim of this work was to determine any changes in heart rate variability (HRV) in a study on craniosacral therapy. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a quasi-experimental (controlled) study with cross-over design. In a private practice, measurements were performed on 31 patients with subjective discomforts before and after a control and an intervention period. HRV was determined using a device that requires a measuring time of 140 s and electrode contact only with the ifngertips. Main PRIMARY OUTCOME MEASURES: HRV change under the inlfuence of a deifned one-time intervention (test intervention) with craniosacral therapy versus control (deifned rest period). RESULTS:Standard deviation of all RR-intervals (ms) and total power of RR-interval variability in the frequency range (ms2) were together interpreted as an indicator of test subjects’ autonomic nervous activity and as a measure of their ability to cope with demands on their health. Neither of these parameters increased during the control period (P>0.05), whereas during the test intervention period there was an increase in both (P<0.05, P<0.01). Nevertheless, interactions between treatment and the increase were statistically not signiifcant (P>0.05). No changes were observed in the low frequency/high frequency ratio (sympathetic-vagal balance) in the course of the control or the test intervention period (P>0.05). CONCLUSION: Craniosacral treatment had a favourable effect on autonomic nervous activity. This in itself is an interesting result, but further research will be needed to distinguish speciifc effects of craniosacral therapy technique from less speciifc therapist-client interaction effects.

A case report of a24-year-old male with a large hemorrhagic pericardiai effusion

Although bloody pericardial effusion often suggests neoplasia,such an event is not rare in tuberculosis (TB),especially in those countries with a high TB disease burden.Meanwhile,TB accounts for 50％ and greater than 90％ of large pericardial effusions in human immunodeficiency virus (HIV)-negative and HIV-positive patients,respectively.Here we report a case of a 24-year-old HIV-negative male who presented with fever and hemorrhagic pericardial effusion.The patient was given presumptive anti-TB treatment before diagnosis was established.Eventually the patient responded well to the anti-TB treatment at the last follow-up and the diagnosis was confirmed by aspirated pericardial fluid culture on LowensteinJensen (LJ) medium.

运用综合心理疗法治疗一例成人考试焦虑症的探讨

Objective:This is a case study in which a 30-year-old male suffering from Examination Anxiety Disorder was treated by Eclectic Psychotherapy. Methods: Using Eclectic Psychotherapy, an approach that combines principles of Client Centeed Therapy, Cognitive Therapy, Rational Emotion Therapy (RET),and Behavior Therapy, the patient was treated for a total of 22 sessions.Results: The study showed obvious therapeutic effect for Eclectic Psychotherapy. The patient reported complete relief of his examination anxiety symptoms at conclusion of treatment. Follow-up by telephone at 1 month and 6 months after treatment showed that the patient remained stable and well.Conclusion: Eclectic Psychotherapy is an efficient way for treating symptoms of severe Examination Anxiety Disorder, both in terms of permanent cure and temporary relief.

Objective: To investigate the changes of the markers of pulmonary vascular endothelial cells (PVECs) after acute lung injury (ALI) induced by bone marrow extract (BME)injection in rabbits.Methods: Thirty-one rabbits were randomized into control (CG, n ＝ 10) and experimental groups (EG, n ＝21). The rabbits in EG were injected with homogeneous bone marrow extract (0.35 ml/kg, 2 ml/h) at a slow and continuous rate through the jugular vein to establish the model of ALI. At 6 h after the injection, the number of circulating endothelial cells (CECs) in the blood, contents of granule membrane protein-140 (GMP-140), angiotensin converting enzyme (ACE) and endothelin-1 (ET-1) in the plasma and the content of GMP-140 in the pulmonary tissue were determined at various time intervals. Then the animals were killed and routine pathological examination and electron microscopy were performed to observe the changes in the pulmonary tissue.Results: The levels of plasma GMP-140, ACE, ET-1and CECs were significantly increased in the early stage (0.5 h) and remained higher for 6 h. The marked increase of plasma GMP-140 (3.25 times) in the early stage was negatively correlated to PaO2, but positively to other parameters. IHC-staining showed that the GMP-140 on the surface of PVECs became weak.Conclusions: BME injection at slow and continuous rate can establish an acceptable model of ALI. Determination of plasma GMP-140 might be an important measure for the early surveillance and the evaluation of prognosis of ALI in clinical management of serious traffic accidents.

A case of a 53-year-old man with adult T-lymphoblastic lymphoma (T-LBL) in mediastinum who survived more than 33 months in our hospital was reported. LBL was more common in school-age and teenage boys than adults. The reported patient manifested progressive dyspnea. Chest CT scanning showed a huge irregular soft tissue shadow in anterior mediastinum which extended into posterior mediastinum and left chest wall. The tumor was 20 cm×15 cm×15 cm in size in left upper mediastinum and its boundaries with pericardium and left lower lung were unclear. The diagnosis of T-lymphoblastic lymphoma was confirmed by immunohistochemical staining. After surgery, he received five chemotherapy courses including Gem, CTX and VCR and biological therapies with IL-2 and IFN-α2b. About 16 months later, he complained of diplopia in the left eye without any evidence of recurrence. Blood examination which showed leukemoid reaction twice returned to normal after dehydration, hormone and thalidomide treatments. Finally, his condition became worse and died of pulmonary infection 33 months after ifrst medical service. In summary, T-LBL is a rare disease which may result in poor prognosis even if the patient has received immediate chemotherapy. Hormone and thalidomide can be applied to treat adult T-LBL.
