In addition, results of measurement in typical white fiber and red fiber indicated that overfeed fatty diet would increase number of white fiber and thickness of red fiber. It suggested that conversion of red fibers into white fibers could be induced.

并对骨骼肌的典型白肌和红肌进行肌湿重的测定及骨骼肌细胞横切面积的测定，发现高脂日粮的摄入可以通过某些特定的代谢途径增加白肌纤维的量，同时使红肌纤维增粗，简而言之即可以诱导红肌纤维的转化。

Clinical diagnostic considerations ranged from benign entities such as rhabdomyoma, intramuscular lipoma, fibromatosis, myositis ossificans, proliferative myositis, inflammatory myofibroblastic tumor, and inflammatory myopathy to malignant entities such as rhabdomyosarcoma, leiomyosarcoma, liposarcoma, and lymphoma.

这些病例的临床考虑多样，有良性的横纹肌瘤、肌内脂肪瘤、纤维瘤病、骨化性肌炎、增生性肌炎、炎性肌纤维母细胞瘤和炎性肌病，也有恶性的横纹肌肉瘤、平滑肌肉瘤、脂肪肉瘤和淋巴瘤。

Arterially perfused rabbit left ventricular preparations were used in the present study to simulate LQT2 by perfusing with d-sotalol. Transmembrane action potentials from epicardium and endocardium were recorded simultaneously, together with a trasmural ECG, in arterially perfused rabbit left ventricular preparations by use of 2 separate intracellular floating mocroelectrodes.

为探讨心室肌跨壁复极离散和心脏兴奋的恢复性质在长QT综合征室性心律失常发生过程中的作用，应用冠状小动脉灌流的兔左室肌楔形组织块标本，分模型组和对照组，采用浮置玻璃微电极法同步记录心室肌内、外膜心肌细胞动作电位和跨壁心电图。

The growth inhibiting rate of T24 cell lines were detected by MTT methods, apoptosis of cells were detected by flow cytometry, the mechanism of apoptosis was analyzed by detecting the protein expression of Bcl-2, Bax, Caspase-9, Caspase-3 and cytoplastic protein Cytochrome C. 4 We injected live T24 cells into the subcutaneous space of nude mice and successfully built up the animal model of bladder carcinoma. The effect of CS-PAA-EPI polymer magnetic microspheres targeting chemotherapy was investigated by HE staining, TUNEL ,tumor weight and volume inhibition rate. Results: 1 TEM revealed that the CS-PAA polymer magnetic microspheres were regular spherical shape,the average diameter was 80nm in dry condition. By controlling the pH value of the medium,polymers had positive or negative zeta potential. VSM showed the CS-PAA polymer magnetic microspheres had superparamagnetic. The diameter of CS-PAA-EPI polymer magnetic microspheres were 200nm in solution by DLS examining,the embedding ratio was 20%,the EPI loading rate was 15%, which was higer than reported in other articles. 2 Raw eye observation found that the rat"s bladder of treatment group was brown color,which meaned the aggregation of iron particles, compared with the control group, iron stain found iron particles were assembled in rat"s bladder of the treatment group, the amount of iron particles in liver and spleen were less obviously.

研究结果：1合成的CS-PAA磁性聚合物微球呈球形，大小均一，TEM测定其干态下粒径为80nm左右，磁化曲线证实具有超顺磁性，具有一定的PH敏感性，固载表柔比星后，水溶液性状稳定，无沉淀物，DLS测定直径约200nm左右，测定载药率为15％，较文献报道高，包封率为20％。2肉眼观察试验组大鼠膀胱表面呈褐色，可见大量的Fe粒子聚集，普鲁士兰染色法显示，试验组大鼠膀胱壁内有大量的Fe粒子，分布至膀胱壁全层，与对照组大鼠相比，试验组大鼠的肝、脾内的Fe粒子聚集量明显降低；HPLC测定结果与Fe染色相同；高剂量磁性CS-PAA-EPI生理盐水组及单纯EPI生理盐水组均在给药后14天出现血肌酐和尿素氮的升高，其他组大鼠血生化指标没有明显变化。3MTT法发现，高、中、低剂量磁性CS-PAA-EPI生理盐水组在外加磁场的协同作用下杀伤T24细胞效应明显高于单纯的EPI生理盐水组，FCM发现试验药物组可引起明显的肿瘤细胞凋亡，试验药物治疗组细胞胞浆内出现了由线粒体释放出的细胞色素C，试验组细胞Bcl-2蛋白减少，Bax蛋白变化不明显，Caspase-3、Caspase-9蛋白受到了激活活化。4高、中、低剂量磁性CS-PAA-EPI生理盐水组的瘤重抑制率和瘤体积抑制率均明显高于单纯的EPI生理盐水组(P＜0.01)，其中高剂量组的抑制率最高。

Results (1) In the controls and the dilated intestine segment of the HD,CAD-positive ganglionic cells were observed in myenteric and submucosal plexus.

结果 （1）在正常对照组与HD扩张段组肠壁肌间和黏膜下层可见CAD只对神经丛中神经节细胞阳性表达，对神经纤维与神经胶质细胞均不表达。S-100染色与CAD染色相反，神经纤维与神经胶质细胞均阳性表达，神经节细胞阴性表达，表现为阳性神经丛中细胞状&空白区&。

Myoblastic cells from patients with PM had a weaker ability of developing into the myotubules, thus they were unable to perform effective regeneration, which resulted in a progressive necrosis. The exogenous bFGF could promote the division and proliferation of the muscle cells in vitro . These results shield a light on bFGF's potential role in preventing and treating PM.

PM患者受损腓肠肌在体外有再生能力，但融合成肌管能力极弱，存在再生障碍，不能对变性、坏死的肌纤维形成有效再生，故呈进行性肌纤维耗竭；外源性bFGF可促进PM患者体外培养骨骼肌细胞增殖分裂，并可促进肌管成熟，对进展性肌病应具有防治作用。

The forced expression of myogenin could induce NIH3T3 fibroblast to differentiate into myogenesis, it was identified as a pair of bands on SDS-PAGE. The phosphorylated form implies a significant structural change in the myogenin protein, which is expected to affect its function at post-translational level.

强制性表达外源性生肌素可启动NIH3T3成纤维细胞分化，进入成肌过程。pCD1-myog转染后的蛋白印迹带型迁移率发生改变，说明磷酸化导致生肌素蛋白结构的明显变化，并可能在翻译后水平影响其功能。

Results Myoid/myofibroblastic differentiation occurred most commonly in fibrosarcomatous DFSP. It was recognized histologically as peripherally distributed or randomly scattered small eosinophilic nodules or short bundles, which were composed of bland spindle cells, closely resembling smooth muscle cells or myofibroblasts.

结果 肌样／肌纤维母细胞性分化多出现在纤维肉瘤型DFSP中，表现为肿瘤周边部或肿瘤内散在性分布的深嗜伊红色小结节或短条束，由梭形细胞组成，细胞多无异型性，核分裂象也罕见，形态上似平滑肌细胞或肌纤维母细胞。

Catecholamine requirements were significantlyless in the treated than in the nontreated patients.
