Objective To study the gait of children with spastic cerebral palsy (SCP) using plantar pressure measurement (PPM).Methods Twenty SCP children and 84 healthy children were recruited,and PPM was used to compare their gait cycle time,cadence,and standardized gait cycle parameters.Results Compared with the control group,gait cycle times in the SCP group were obviously prolonged,and their cadence was significantly slower.The side support phase and swing time in the SCP group were shorter,while the double support phase was longer than that of children in the control group.Conclusion PPM can be used to assess the gait of SCP children efficiently.

This study examined the effects of arsenic trioxide on apoptosis and interleukin-4 release in T cells of asthmatic patients in vitro and investigated the role of Bcl-2 in the active mechanism. T cells were isolated from asthmatic patients (n = 21) and healthy controls (n = 20), and then treated with arsenic trioxide and dexamethasone. Cell apoptosis was measured using fluorescence microscopy, flow cytometry and a cytochrome c ELISA kit. Interleukin-4 levels in the serum and in supernatants from T cells were quantified by ELISA. Flow cytometric analysis and immunofluorescence studies were performed to determine Bcl-2 expression. T cells of the asthmatic patients (i. e. without treatment) exhibited decelerated spontaneous apoptosis after 24 h incubation in vitro when compared to T cells of the healthy controls. With dexamethasone treatment, an increase in apoptosis of T cells was not significantly different between both groups, irrespective of the method used. Arsenic trioxide treatment, however, significantly increased the apoptosis of T cells of the asthmatic group and showed a slight effect on the control group. In asthmatic patients, elevated levels of interleukin-4 and up-regulated Bcl-2 expression were detected. Moreover, in vitro, T cells of asthmatic patients spontaneously released more interleukin-4 and exhibited more Bcl-2 expression than T cells from the control group. Arsenic trioxide treatment significantly decreased interleukin-4 release and down-regulated Bcl-2 expression in asthmatic patients, while it only slightly affected healthy controls. Dexamethasone treatment decreased interleukin-4 release in both groups examined. It did not significantly influence Bcl-2 expression. These results suggest that arsenic trioxide induces T cell apoptosis and decreases interleukin-4 release in T cells of asthmatic patients in vitro and that down-regulation of Bcl-2 expression may be an important mechanism.

An increasing number of monopartite begomoviruses are being identified that a satellite molecule (DNAbeta) is required to induce typical symptoms in host plants. DNAbeta encodes a single gene (termed betaC1) encoded in the complementary-sense. We have produced transgenic Nicotiana benthamiana and N. tabacum plants expressing the betaC1 gene of a DNAbeta associated with Tomato yellow leaf curl China virus (TYLCCNV), under the control of the Cauliflower mosaic virus 35S promoter. Transgenic plants expressing betaC1 showed severe developmental abnormalities in both species. Microscopic analysis of sections of both transgenic and non-transgenic N. tabacum leaves showed abnormal outgrowths of transgenic N. tabacum to be due to disorganized cell division (hyperplasia) of spongy and palisade parenchyma. Immuno-gold labeling of sections with a polyclonal antibody against the betaC1 protein showed that the betaC1 protein accumulated in the nuclei of cells. The possible biological function of the betaC1 protein was discussed.

Objective To develop a better method for preparation of porcine model of acute myocardial infarction by permanent occlusion of the left circumflex coronary artery and minimally invasive surgery, evaluate its validity and stability, and explore its application in experimental studies of ischemic heart diseases.Methods 25 healthy female 3-month-old Bama minipigs, body weight 25±3 kg, were used in this study.The porcine model of myocardial infarction was established by minimally invasive surgery and the left circumflex artery ligation at the site of OM1 posterior position under general anesthesia.Heart function was assessed by echocardiography at 15 min before surgery, 1 hour and 4 weeks after surgery.Pathological examination was performed at 4 weeks after the left circumflex artery occlusion.The mortality and cause of death were statistically analyzed.Results The 1-hour and 4-week postoperative cardiac function was considerably decreased, showing a decreased ejection fraction from 64.2±4.6% to 48.2±5.3% (1hour after MI) and 49.7±6.1% (4 weeks after MI) (P<0.01).Pathological examination revealed that the ventricular wall was thinner and the amount of collagens was increased in the infracted area.The ventricular fibrillation rate at 1-hour after myocardial infarction was 17.3% and the infarction area was 19.2%.Conclusions A pig model of acute myocardial infarction can be prepared by our modified left circumflex coronary artery ligation at the obtuse marginal artery (OM1) and minimally invasive surgery.This model exhibits advantages such as minimal surgical trauma, high stability of the model, and low mortality, therefore, provides an ideal and economic animal model for experimental studies on acute ischemic heart diseases.

OBJECTIVETo study the effects of arsenic trioxide on apoptosis of peripheral T-lymphocytes from asthmatic patients and normal subjects in vitro.

METHODSThe T-lymphocytes were isolated from the blood of 21 asthmatic patients and 20 healthy controls and treated with arsenic trioxide and dexamethasone. Cell apoptosis was observed by fluorescence microscope and measured with flow cytometry and Cytochrome C ELISA kit.

RESULTSThe T-lymphocytes from the asthmatic patients, when compared to those from of the healthy control, exhibited decelerated spontaneous apoptosis after a 24-hour incubation in vitro. Dexamethasone treatment significantly increased the percentage of apoptotic T-lymphocytes from both asthmatic patients and normal subjects in comparable magnitude. Arsenic trioxide treatment, in contrast, significantly increased the percentage of apoptotic T-lymphocytes from asthmatic patients, but slightly affected the cells from the control group.

CONCLUSIONSSpontaneous apoptosis of T-lymphocytes can be decelerated in asthmatic patients, whose T-lymphocytes are more sensitive to arsenic trioxide-induced apoptosis than those of normal subjects, but the T-lymphocytes from normal subjects and asthmatic patients are equally sensitive to dexamethasone.

OBJECTIVETo explore the effect of Chang'an No. I Recipe (CA) on 5-hydroxytryptamine signal system and mRNA expression levels of hippocampal brain derived neurotrophic factor (BDNF) in visceral hypersensitivity model rats with irritable bowel syndrome (IBS).

METHODSIBS visceral hypersensitivity rat models were established by combined chronic restraint stress and forced swimming. Successfully modeled rats were randomly divided into the model group, the Dicetelgroup (27 mg/kg) , the Fluoxetine group (3.6 mg/kg), the high dose CA group (22.6 mg/kg), the medium dose CA group (11.3 mg/kg), and the low dose CA group (5.7 mg/kg) according to body weight, 9 in each group. Besides, a normal control group with 10 rats was set up. Corresponding medication was administered to rats in each treatment group. Equal volume of physiological saline was administered to rats in the model group by gastrogavage. All medication was performed once per day for a total of 14 days. Pain threshold was determined by abdominal withdrawal reflex (AWR). Changes of colon 5-HT levels were determined by immunohistochemical assay. mRNA expression levels of hippocampal 5-hydroxytryptamine 1A receptor (5-HT1a) and BDNF were detected by immunofluorescent RT-PCR.

RESULTSCompared with the normal control group before treatment, pain threshold was obviously lowered in proctectasia rats of each group (P < 0.01). Compared with the normal control group after treatment, pain threshold was obviously lowered in rats of the model group; colon 5-HT levels, mRNA expression levels of hippocampal 5-HT1a and BDNF were obviously elevated (P < 0.01). Compared with the model group, pain threshold was obviously elevated in the Fluoxetine group and all CA groups; colon 5-HT levels were obviously reduced in the Dicetel group, high and medium dose CA groups (P < 0.05, P < 0.01); mRNA expression levels of hippocampal 5-HT1a and BDNF were obviously reduced in each CA group (P < 0.01); mRNA expression levels of hippocampal BDNF were obviously reduced in the Fluoxetine group (P < 0.01).

CONCLUSIONSThe target points of CA were involved in brain and gut. CA could reduce pain threshold of proctectasia rats, down-regulate colon mucosal 5-HT levels, and lower mRNA expression levels of BDNF and 5-HT1a in rat hippocampus.
