ObjectiveTo research the protective mechanism of acupoint iontophoresis to the heart function.Methods46 SD rats were randomly divided into 5 groups. The methods of histology, transmission electron microscope and radioimmunoassay were used respectively to observe the influence of acupoint iontophoresis on rats' heart ultrastructure.ResultsAcupoint iontophoresis could prolong rats' exertion period, protect ultrastructure of heart and prevent it from abnormal accretion. Over training would cause unbalance secreting between endothelin (ET) and calcitoningene related peptide (CGRP), while acupoint iontophoresis could improve such situation.ConclusionThe rise of exercise induced fatigue is related to many factors; acupoint iontophoresis can protect cardiac muscle, improve heart function and prevent it from exercise induced fatigue via several ways.

The mechanism of chromium accumulation and microstructure transformation of the fused yeast were studied in this paper.The result showed that the process of Cr6+ reduction and adsorption was accom-panied by the H+ consumption.The main adsorptive groups on the strain surface included amino,hydroxyl,phosphate group and amide,among which phosphate group played vital role in the chromium accumulation.The removal rate of chromium and reduction rate of hexavalent chromium declined 70% and 46%,respec-tively,when phosphate group was masked.During the adsorption process the chromium ions complexed on the surface of fused yeast was transported into the cell wall and combined with inclusion to form steady spe-cies and this took 90 min to reach the equilibrium.The biosorption and reduction of Cr on the cell surface would alter microstructure of cell surface,reduce cell membrane potential and increase cell membrane per-meability.

At present, current situation of syndrome differentiation-based treatment in clinical acupuncture and moxibustion has brought about concern of scholars at home and abroad. Acu-moxibustion doctors on Japan point out that a great number of corrupt practice in clinical treatment, which should be paid to enough attention. Based on the question put forward by the Japanese doctor, this article points out the main existing problems and analyzes some opinions, for which people may hold different viewpoints. The "syndrome differentiation-based treatment" is embodied in the scientific and orderly application of "principles, methods, prescriptions, acupoints and techniques" in the clinical practice. To achieve the purpose of improving the therapeutic effect, the clinical techniques, action regularity, indications and influential factors, etc. should further be studied.

Vascular stent is an important medical appliance for angiocardiopathy. Its key deformation process is the expandable progress of stent in the vessel. The important deformation behaviour corresponds to two mechanics targets: deformation and stress. This paper is devoted to the research and development of vascular stent with proprietary intellectual property rights. The design of NiTinol self-expandable stent is optimized by means of finite element software. ANSYS is used to build the finite element simulation model of vascular stent; the molding material is NiTinol shape memory alloy. To cope with the factors that affect the structure of stent, the shape of grid and so on, the self-expanding process of Nitinol stent is simulated through computer. By making a comparison between two kinds of stents with similar grid structure, we present a new concept of "Optimized Grid" of stent.

Objective To explore the effect of electroacupuncture and transcutaneous electrical acupoint stimulation (TEAS) on somatosensory evoked potential (SEP) of the upper extremity in healthy subjects. Methods From October, 2015 to April, 2016, ten healthy young volunteers were selected. Each of the subjects was randomly treated with electroacupuncture and TEAS. Before and after treatment, the latency and amplitude of N20 and N9 of SEP were detected. Results After electroacupuncture, the latency of N20 prolonged in the stimulated side (Z=-2.620, P<0.01); the latency of N9 prolonged (Z=-2.454, P<0.05), and the amplitude of N9 decreased (Z=-2.330, P<0.05) in the non-stimulated side. After TEAS, the latencies of N9 both in the stimulated side and the non-stimulated side prolonged (Z>2.695, P<0.01). There was no significant difference in the D-value of latency and amplitude of N20 and N9 in both two sides between two treatments (Z<1.817, P>0.05). Conclusion Both electroacupuncture and TEAS could affect the latency and amplitude of N20 and N9, and no difference was found between two treatments.

BACKGROUNDPeroxisome proliferator activated receptor gamma (PPARgamma) is a ligand-activated transcription factor. Activation of PPARgamma has recently been demonstrated to inhibit various tumor cells growth, progression and metastasis. E-cadherin-mediated cell adhesion system is now considered to be an "invasion suppressor system" in cancer tissues. Matrix metalloproteinases-2 (MMP-2) is a prerequisite for metastasizing tumor cells. However their correlation is still unknown in gastric carcinoma. The aim of this study was to assess the expression of PPARgamma, E-cadherin, MMP-2 and their correlation in gastric carcinoma and metastases.

METHODSGastric carcinoma tissues and their corresponding lymph nodes with metastases and the adjacent non-tumor tissues were obtained from 54 patients with gastric cancer who underwent gastrectomy. Expression of PPARgamma, E-cadherin and MMP-2 was assessed by immunohistochemical staining.

RESULTSThe nuclear expression level of PPARgamma in neoplastic cells was significantly lower than that in the normal controls (P < 0.001), with the expression of PPARgamma being weaker in primary tumors compared with that in metastases. In all neoplastic cells, E-cadherin was expressed with abnormal patterns (cytoplasm pattern, cytoplasm and membrane pattern or absent), compared with normal cells where E-cadherin was expressed with a normal pattern (membrane pattern). Compared with the normal tissues, the expression level of E-cadherin decreased in primary tumors and further decreased in metastases (P < 0.001). Membrane staining of MMP-2 was detected in the foveolar epithelia of normal gastric mucosa, whereas predominant cytoplasm staining of MMP-2 was found in malignant tissues. The expression of MMP-2 was stronger in metastatic tissues than in primary tumors. In neoplastic foci the expression of PPARgamma was negatively correlated with MMP-2 expression (P < 0.05). However, there was no correlation between E-cadherin and PPARgamma or MMP-2 expression.

CONCLUSIONSDown-regulation of PPARgamma and E-cadherin and up-regulation of MMP-2 in neoplastic foci might be helpful to gastric carcinogenesis and metastases. An inverse relationship between PPARgamma and MMP-2 in human gastric carcinoma suggests that PPARgamma might modulate MMP-2 expression and affect gastric cancer metastases.
