Objective To observe the influence of GT-4A Pulse Acting Working station on clinical intrapar-tum pain,and its influence on the stages of labor,the way of delivery,the volume of postpartum hemorrhage and the complications of neonates. Methods 400 primiparous women were randomly divided into two groups. The test group had 200 women who received analgesia from GT-4A Pulse Acting Working Station; while the control group had the other 200 women who received no means of analgesia. The degree of pain,duration of labor, way of delivery ,the volume of two hours after delivery and the adverse effect on fetus were observed. Results The degree of pain was significantly reduced by GT-4A Intrapartum Analgesia Working Station(P <0.01). The active stage,the first stage of labor and the second stage of labor in test group were decreased compared with control group ( P < 0.05). The ratio of cesarean section were significantly higher than that in test group. The influence of postpartum hemorrhage and complications of neonates were not different between the two groups. Conclusion The GT-4A Pulse Acting Working Station could be used as a non-drug analgesic method during labor,itis easy operation,significant effect of analgesia,shorten the stages and ratio of cesarean section and no adverse influence to either mother or neonate.

Background:The ability of tumor cells to evade destruction by immune system is known as tumor immune escape. Regulatory T cells( Treg cells)and myeloid-derived suppressor cells( MDSCs)are considered to be the most critical cell subsets participating in tumor immune escape. Aims:To determine the percentages of Treg cells and MDSCs in peripheral blood of patients with gastric cancer for investigating the effects of these two cell subsets on development and progression of gastric cancer. Methods:Peripheral blood specimens from 77 patients with gastric cancer and 20 healthy controls were collected for measurements of CD4+CD25+Foxp3+ Treg cells and MDSCs by flow cytometry. Correlations between Treg cells,MDSCs and clinicopathological characteristics of gastric cancer were analyzed. Results:Percentage of CD4+CD25+Foxp3 + Treg cells in peripheral blood CD4+ T cells and percentage of MDSCs in peripheral blood mononuclear cells were both significantly higher in gastric cancer patients than in healthy controls( Treg cells:4. 72% ± 1. 01% vs. 1. 57% ± 0. 99%,P<0. 01;MDSCs:21. 72% ± 10. 12% vs. 2. 90% ± 1. 80%,P<0. 01). Percentage of Treg cells in peripheral blood was correlated with the clinical stage,depth of invasion and lymph node metastasis of gastric cancer(P<0. 05), while percentage of MDSCs was correlated with the clinical stage of gastric cancer(P<0. 05). Furthermore,a significant positive correlation was observed between percentages of Treg cells and MDSCs in peripheral blood of gastric cancer patients ( rs =0. 681,P<0. 01). Conclusions:Gastric cancer patients are characterized by high expressions of immunosuppressive cells in peripheral blood,such as Treg cells and MDSCs,which might be related with the development and progression of gastric cancer via tumor immune escape.

[Objective]To explore the clinical experience of Professor Chen on treating Meniere Disease by acupuncture and Chinese medicine.[Method] By col ecting clinical cases and combining with the record of Professor Chen ’s clinical experience, sorting and analyzing the theory and method of Professor Chen Huade’s clinical treatment on Meniere Disease.[Result] Professor Chen emphasizes acupoints selection treatment on the basis of syndrome differentia-tion, applies body acupuncture, scalp acupuncture and ear acupuncture, moreover focuses on the combination of traditional Chinese medicine in his diagnosis and treatment on Meniere Disease, which is based on the Chinese medicine theory “treating disease from the root”.[Conclusion] Professor Chen has his own insights on treating Meniere’s disease by combining acupuncture with traditional Chinese medicine treatment on Meniere Disease.“This”method has signifi-cant effect in clinic, it worths spreading.

The infection rate of human cytomegalovirus (CMV) in the general population in our country is very high.The latent virus often becomes activated when patients' immune status turned to immunocompromised,which will cause serious clinical consequences.Because the manifestations of cytomegalovirus infection are nonspecific,the diagnosis of cytomegalovirus infection mainly depends on the laboratory tests.This article will review laboratory diagnostic methods and clinical significance of CMV infection in immunosuppression patients.

With the advent of continuous development of radiofrequency ablation(RFA), this technique has been increasingly used in the treatment of renal cell carcinomas during recent years, with a significant therapeutic effect clinically. RFA is characteristic with the advantages of safety, convenience, minimal invasion, less complications and suffering. The improvement of the electrode needle, the radiofrequency techniques and the combination of other treatments are the key of the development of RFA in the near future. And more reasonable criteria for evaluating the therapeutic effects including imaging techniques are also needed to be set up.

The rather serious compliation of vertebroplasty is caused by bone cement leakage into adjacent structure but recent research suggests that even without cement leakage during vertebroplasty,patients could also experience with cardiovascular changes sometimes. Cytotoxicity of bone cement,nervous reflex,fat embolism and alteration of intravertebral pressure may be responsible for these changes. (J Intervent Radiol,2006,15: 377-381)

Quality assurance(QA) and Quality Control(QC) of MRI has become very realistic and imperative,which can ensure safety and availability of MRI and improve diagnosis quality.From the practice of the daily grind of MR,the connotation and main content of MR QA and QC are discussed.It is illuminated that MR QA and QC not only should be standardized and systemized,but also needs leaders' recognition and everyone's participation.The responsibility of medical engineers includes emergency maintenance,preventive maintenance,optimization of sequences and parameters,development and application of new techniques Clinical engineers play an irreplaceable and important role in the whole process of MR QA/QC.

The effect and value that are assurance of standard operation in quality control and administration of digital im- ages were discussed. The putting forward concept and aim of standard operation were classified into four grades: best, good, checkout and below standard according to evaluating factors and conditions of standard operation. In order to guarantee the implementation of quality control, medical staff should renew ideas and enhance the consciousness of quality control. The standard operation can be guided and supervised by the director in machine and the system of rewards and penalties can be established. The standard operation has important significance and values, which carry out quality control and quality ad- ministration in medical imaging effectively.
