Objective To observe the effect of scalp-acupuncture combined with physical therapy on spastic cerebral palsy.Methods 80 children with spastic cerebral palsy were randomly divided into observation group and a control group,40 cases in each group.The observation group was treated with scalp-acupuncture combined with physical therapy,and the control group with physical therapy only.They were assessed with the Functional Independence Measure for children(WeeFIM) and the Gross Motor Function Measure(GMFM) before and 3 months after treatment.Results No side-effect was observed during the treatment.The scores of WeeFIM and GMFM of the observation group were significantly superior to the control group(P<0.05).Conclusion The scalp-acupuncture can improve the efficiency of physical therapy on motor function in the children with spastic cerebral palsy.

Pathological pain, normally referring to tissue injury-induced inflammatory pain and nerve injury-induced neuropathic pain, is an expression of neural plasticity. Injuries and intense noxious stimuli result in pain hypersensitivity,which is contributed by peripheral sensitization (increased sensitivity of primary sensory nociceptors) and central sensitization (increased sensitivity of spinal dorsal horn and other CNS neurons). Activation of several protein kinases causes both forms of sensitization via posttranslational regulation, such as phosphorylation of key membrane receptors and channels. In particular, activation of multiple signal cascades converge on the activation of MAPK (mitogen-activated protein kinase).Activation of MAPK family members of ERK and p38 by nociceptive activity, growth factors, and inflammatory mediators in primary sensory and secondary order neurons, not only results in posttranslational modification, but also increases the expression of numerous genes via transcriptional and non-transcriptional regulation. Eventually this activation contributes to the development and maintenance of heightened pain sensitivity following injury.

The pain experience includes a sensory-discriminative and an emotional-affective component. The sensory dimension describes the quality, intensity, and spatio-temporal characteristics of the sensation. The affective dimension refers to the unpleasantness or aversion of sensation. The great progress at the genic, molecular, cellular, and systemic level on the study of the sensory dimension of pain has been made over past four decades. However, to consider only the sensory features of pain, and ignore its motivational and affective properties, is to look at only part of the problem. A line of clinic observations indicate that the patients with chronic pain suffer from much more affective disturbance than pain itself. Obviously, physiological arousal and hypervigilance to pain cause negative affect, such as fear, anxiety, angry, worry, aversion, even tendency of suicide, these negative affective states in turn enhance pain sensation. Therefore, the mechanisms underlying the affective dimension of pain have recently received more attention. In order to deepen and expand our understanding of the nature of pain, this review summarizes the main findings regarding affective component of pain in neuroanatomy, neurophysiology, and cell biochemistry

OBJECTIVETo observe the effect of Qianliean Pill (QP) on inflammatory factors such as IL-1β, IL-10, and tumor necrosis factor α (TNF-α) in chronic nonbacterial prostatitis (CNP) model rats, and to explore its therapeutic mechanism.

METHODSCNP rat model was established by castration and estradiol benzoate injection. Totally 50 rats were randomly divided into 5 groups, i.e., the model group, the positive medicine group, the high dose QP group, the medium dose QP group, and the low dose QP group, 10 in each group. Besides, 10 normal rats were recruited as a normal control group. Since the 8th day of castration, Pulean Tablet (PT) at 10. 80 g/kg was administered to rats in the positive medicine group by gastrogavage. QP at 11.00, 5.50, and 2.75 g/kg was administered to rats in high, medium, and low dose QP groups by gastrogavage. Distilled water at 2 mL/100 g was administered to rats in the model group and the normal control group by gastrogavage, once daily for 30 successive days. After 30 days of medication all rats were sacrificed and their prostate tissues were extracted. The prostatic index was calculated. Pathological changes of rat prostate were observed under light microscope. Meanwhile, levels of IL-1β, IL-10, and TNF-α were detected using enzyme linked immunosorbent assay.

RESULTSCompared with the normal control group, the prostate index obviously decreased, levels of IL-1β, TNF-α, and IL-10 in the prostate tissue significantly increased in the model group (P < 0.01). Compared with the model group, the prostate index obviously decreased in high and medium dose QP groups, and the positive medicine group (P < 0.01); levels of IL-1β, TNF-α, and IL-10 obviously decreased in each QP group and the positive medicine group (P < 0.01). Compared with the positive medicine group, the TNF-α level decreased more obviously in the high dose QP group (P < 0.05). Compared with the normal control group, inflammatory reactions occurred obviously in rats' prostate of the model group. Compared with the model group, inflammatory reactions were milder in rats' prostate of each QP group and the positive medicine group, and their degrees were improved to some extent.

CONCLUSIONQP could treat CNP, which might be achieved by regulating local immune state of the prostate, relieving inflammatory reactions of the prostate, and lowering levels of IL-β, TNF-α, and IL-10 in the prostate tissue.

OBJECTIVETo investigate the effect of baicalein on the gap junction intercellular communication (GJIC) in the TM4 Sertoli cells of the mouse testis and its related mechanism.

METHODSWe measured the cytotoxicity of different concentrations of baicalein on the TM4 Sertoli cells in the mouse testis by MTT, detected the fluorescence transfer of the TM4 Sertoli cells by parachute assay, and determined the expression of the protein connexin 43 ( Cx43) in the baicalein-treated cells by Western blot and immunofluorescence assay.

RESULTSBaicalein produced no obvious cytotoxicity on the TM4 Sertoli cells at the concentration below 60 µmol/L but significantly increased their GJIC at 0-20 µmol/L (P < 0.01). Western blot and immunofluorescence assay showed that 0-20 µmol/L baicalein remarkably elevated the expression of Cx43 in the TM4 cells (P < 0.01) and on the membrane of the TM4 cells.

CONCLUSIONBaicalein at the concentration of 0-20 µmol/L can significantly enhance GJIC in mouse TM4 Sertoli cells by increasing the expression of the Cx43 protein.
