Sudden cardiac arrest is one of the critical clinical syndromes in emergency situations. A cardiopulmonary resuscitation (CPR) is a necessary curing means for those patients with sudden cardiac arrest. In order to simulate effectively the hemodynamic effects of human under AEI-CPR, which is active compression-decompression CPR coupled with enhanced external counter-pulsation and inspiratory impedance threshold valve, and research physiological parameters of each part of lower limbs in more detail, a CPR simulation model established by Babbs was refined. The part of lower limbs was divided into iliac, thigh and calf, which had 15 physiological parameters. Then, these 15 physiological parameters based on genetic algorithm were optimized, and ideal simulation results were obtained finally.

· Mesenchymal stem cells ( MSCs ) are a population of multipotent stem cells with various neurotrophins from bone marrow which are widely used in tissue, cell repair and alternative research.Recently, some researches have shown that MSCs could enhance the viability of neurons under a pathological circumstance by secreting some neurotrophins. So the neuroprotection of MSCs can provide a new method of the treatment on retinopathy that it possible to promote cells survial and functional recovery.Here we make a brief review on the secretory function of neurotrophin and neuroprotective effects of MSCs on retinal cells and its application in the treatment of retinal disease.

Objective To evaluate the use of magnifying endoscopy combined with narrow band im-aging (NBI) system in diagnosis of early gastric cancer. Methods From March 2008 to December in 2008, a total of 56 patients with suspected gastric mucosal lesions were enrolled in the study. The lesions were ob-served with magnifying endoscopy combined with NBI and indigo-earmine-chromoendoscopy, and the results were compared with pathologic diagnosis from targeted biopsies. Results Out of 56 patients, 16 were diag-nosed as early gastric cancer pathologically. The accordance rate with the pathological diagnosis, sensibility, specificity, false positive rate and false negative rate of the magnifying endoscopy combined with NBI system were 94.6% (53/56), 93. 8% (15/16), 95.0% (38/40), 5.0% (2/40) and 6. 3% (1/16), respec-tively; while those of chromoendoscopy were 91.1% (51/56), 87. 5% (14/16), 92. 5% (37/40), 7. 5% (3/40) and 12. 5% (2/16), respectively (P >0.05). There was no difference between NBI and chro-moendoscopy in regarding of observing pit pattern, however, NBI was superior in displaying intrapapillary capillary loop. Conclusion Combination of magnifying endoscopy and NBI provides clear images of gas-tric mucosa and intrapapillary capillary, which is useful in diagnosis of early gastric cancer and can improve accuracy of biopsy. When combined with chromoendoscopy, it can further improve the yield of diagnosis.

OBJECTIVETo evaluate the clinical efficacy of warming-needle moxibustion on cervical headache.

METHODSSixty-one patients of cervical headache were randomly divided into a warming-needle moxibustion group (30 cases) and an acupuncture group (31 cases). Tianzhu (BL 10), Fengchi (GB 20), Wangu (GB 12), Tianyou (TE 16), Hegu (LI 4), Taichong (LR 3) and Zulinqi (GB 41) were selected in the two groups. Patients in the acupuncture group were treated with acupuncture; patients in the warming-needle moxibustion group were treated with warming-needle moxibustion at Tianzhu (BL 10), Fengchi (GB 20) and Wangu (GB 12) and acupuncture at the remaining acupoints. The treatment was given once every other day, 3 times a week, and totally 4-week treatment was given. The duration and frequency of headache, numerical rating scale (NRS) of headache and cervical range of motion (ROM) were compared before and after treatment in the two groups; also the efficacy of the two groups was evaluated.

RESULTSAfter treatment, the duration and frequency of headache, headache NRS.and cervical ROM score were improved in both groups (all P < 0.05), which were more significant in the warming-needle moxibustion group (all P < 0.05). The total effective rate was 84.3% (25/30) in the warming-needle moxibustion group, which was significantly superior to 61.3% (19/31) in the acupuncture group (P < 0.05).

CONCLUSIONThe warming-needle moxibustion presents significant efficacy on cervical headache, which can obviously improve headache symptoms and cervical ROM.

Objective To explore the influence of follow-up by telephone on adherence and quality of life for breast cancer patients with hormonal therapy.Methods Totally 78 breast cancer patients with hormonal therapy were divided into the intervention group (40 cases) and the control group (38 cases).The control group were carried on routine guidance treatment and enjoined regular subsequent visit.The patients in intervention group were carried on the above-mentioned treatment and also receive regular follow-up by telephone.Through the follow-up by telephone we provided guidance for present and will present problems.Adherence for breast cancer patients with hormonal therapy and cancer rehabilitation evaluation system-short form(CARES-SF) were used to investigate the patients' adherence and quality of life six month after the intervention.Then we compared the adherence and quality of life before,six month of the intervention.The changes of adherence and quality of life scores were analyzed by repeated-measure ANOVA.Results The score of quality of life in the intervention group after 6 month of intervention was (25.43 ± 6.04),while in the control group was (40.61 ± 7.73),the difference was significant between the two groups,P＜0.05.The score of medication adherence in the intervention group after 6 month of intervention was (8.57 ± 6.20),while in the control group was (14.12 ± 6.63),the difference was significant between the two groups,P＜0.05.Conclusion Follow-up by telephone can improve adherence and quality of life for breast cancer patients with hormonal therapy.

With the development of the thoracic surgery, clinicians are paying more and more attention to acute lung injury (ALI) following thoracic surgical procedures. Many factors may cause ALI during the operation. This review updates recent researches on the pathogenesis and treatment strategies of the ALI in thoracic surgical procedures.

The traditional Najiafa (day-prescription of acupoints) can be classified into two schools of YAN Ming-guang and XU Feng. The author studied the YAN Ming-guang and XU Feng Najia fa from the aspects of the academic source, selection of points, existing researches and current application. When compared between the two schools, it is held that Najia fa of YAN Ming-guang school more accords with the law of point selection according to Ziwu Liuzhu Zhenfa (acupuncture based on the midnight-noon and ebb-flow doctrine) in following the original doctrine, selection of points on the base of day-prescription, and time-meridian relation of Sanjiao (triple energizer) and Pericardium meridians. Therefore, it is concluded that the YAN's Najia fa should not be neglected and forgotten. Its inheritage and further study should be carried out so as to enrich the ways of study as well as the prevention and treating methods in clinic.

Memory T cells play an important role in the pathogenesis of tumors as a result of the long term of tumor immunity and the heterogeneity of T cells. Great progress in the studies on the generation, classification, mechanism of maintenance and function of memory T cells in tumor immunity have been made in recent years, which may facilitate our understanding of immunological memory and the clinical therapy of tumor.
