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.

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.

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.

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.

OBJECTIVETo compare the therapeutic effect and side effect of the treatments on hyperthyroid exophthalmos with the combination of acupuncture and medication and with medication only.

METHODSFifty-two cases were randomly divided into an acupuncture and medication group (27 cases) and a medication group (25 cases). Acupuncture in combination of oral taking of Thiamazole and Euthyrox were adopted for the acupuncture and medication group. And acupoints such as Jingming (BL 1), Chengqi (ST 1) and Sizhukong (TE 23) etc. were selected. Western medication for oral taking was applied as the only treatment for the medication group. Objective eye syndrome marks, side effects and accidents were compared between two groups before and after treatment.

RESULTSThe improvement of the objective marks of eye syndrome in the acupuncture and medication group was better than that in the medication group (P < 0.01). There were 4 cases with hypoleucocytosis, 3 cases with rash and 3 cases with aggravated symptom of exophthalmos in the medication group during the treatment, while no case with side effects was observed in the acupuncture and medication group. However, 8 cases were found with hemorrhage and 8 with hematoma in the acupuncture and medication group.

CONCLUSIONTreatment with the combination of acupuncture and medication may not only enhance the therapeutic effect, but also reduce the side effects.

OBJECTIVETo explore the feasibility and safety of enteral nutrition in preoperative bowel preparation for rectal cancer patients undergoing radical operation.

METHODSSixty rectal cancer patients undergoing selective low anterior resection were randomized into the trial group(n=30) and the control group(n=30). Patients in the trial group received clean liquid integral protein diet for 3 days before operation without mechanical bowel preparation. Patients in the control group received traditional diet and mechanical bowel preparation. The intraoperative and postoperative clinical data, the quality of bowel preparation, postoperative complications, and nutritional parameters were compared between the two groups.

RESULTSThere were no significant differences in clinicopathological characteristics between the two groups before operation. The operative time, blood loss, quality of bowel preparation as well as postoperative hospital stay were not significantly different(all P>0.05). While the time to first flatus [(2.53±0.91) d vs. (3.03±0.68) d] and semi-liquid diet intake[(3.95±0.83) d vs. (4.52±1.14) d] were significantly shorter in the trial group as compared with the control group(all P<0.05). There were no death and no significant difference in postoperative complications [16.7%(5/30) vs. 20.0%(6/30), P>0.05]. The levels of postoperative total protein, albumin, and prealbumin decreased significantly. Meanwhile, the levels of postoperative albumin[(36.2±2.5) g/L vs. (33.5±2.6) g/L, P<0.01] and prealbumin [(325.4±28.2) mg/L vs. (302.5±34.2) mg/L, P<0.01] in the trial group were significantly higher than those in the control group.

CONCLUSIONSPreoperative enteral nutrition can replace the mechanical bowel preparation with better efficacy, and improve the postoperative nutritional status without increasing surgical risk in rectal cancer patients undergoing radical operation.
