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.

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.

Objective To investigate the clinical efficacy of CRRT in the treatment of severe pancreatitis.Methods 120 patients with severe pancreatitis were divided into two groups according to the treatment.All the patients were given basic treatment in all groups.The Pa arterial oxygen pressure (PaO2),oxygenation index (PaO2/FiO2),and C-reactive protein (CRP) in the two groups after 72 hours of treatment were observed.The levels of blood lactate (Lac),APACHEII,tumor necrosis factor α(TNF-α),interleukin-6 (IL-6) and interleukin-1β (IL-1β) were measured before and after treatment 72 hours.A comparison of mortality and hospitalization time was observed in 28 days of treatment.Results After treatment,Lac [the control group (3.32±0.85)mmol/L,the observation group (2.55±0.65)mmol/L],APACHEII score [the control group (13.30±2.80)points,the observation group (12.01±2.60)points],CRP [the control group (24.30±2.80)mg/L,the observation group (12.33±1.60)mg/L] were significantly lower than before treatment [Lac:the control group (4.85±1.05)mmol/L,the observation group (4.90±1.02)mmol/L;APACHEII score:the control group (16.62±2.95)points,the observation group (16.90±3.01)points;CRP:the control group (40.32±3.10)mg/L,the observation group (40.40±3.51)mg/L;the control group:tLac=1.67,P=0.004,tAPACHEII=6.32,P=0.000,tCRP=29.71,P=0.000;the observation group:tLac=15.05,P=0.005,tAPACHEII=9.52,P=0.000,tCRP=56.36,P=0.000].PaO2 [the control group (75.30±4.80)mmHg,the observation group (84.31±4.60)mmHg], PaO2/FiO2 [the control group (225.30±14.83)mmHg,the observation group (256.31±14.65)mmHg] were significantly higher than before treatment [PaO2:the control group (60.32±4.15)mmHg,the observation group (60.40±4.01)mmHg;PaO2/FiO2:the control group (130.39±11.15)mmHg,the observation group (130.90±11.01)mmHg;the control group:tPaO2=18.29,P=0.000,tPaO2/FiO2=39.62,P=0.000;the observation group:tPaO2=30.35,P=0.000,tPaO2/FiO2=53.01,P=0.000].Those in the observation group were significantly improved than the control group (tLac=5.574,P=0.00,tAPACHEII score=2.615,P=0.005,tPaO2=3.646,P=0.0002,tPaO2/FiO2=11.523,P=0.00,tCRP=28.751,P=0.000).After treatment,the TNF-α,IL-6 and IL-1β levels in the two groups [the control group:IL-1β (70.32±6.85)ng/mL,IL-6 (103.30±8.80)ng/mL,TNF-α (89.30±8.80) ng/mL;the observation group:IL-1β(48.55±6.62)ng/mL,IL-6(92.01±8.60)ng/mL,TNF-α(57.31±7.60)ng/mL] were significantly improved than before treatment [the control group:IL-1β(82.85±7.05)ng/mL,IL-6(173.62±9.95)ng/mL,TNF-α (105.32±9.15)ng/mL;the observation group:IL-1β(83.90±7.32)ng/mL,IL-6 (175.90±10.01)ng/mL,TNF-α (106.40±9.01)ng/mL;the control group:tIL-1β=9.66,P=0.000,tIL-6=41.01,P=0.000,tTNF-α=9.77,P=0.000;the observation group:tIL-1β=27.74,P=0.000,tIL-6=49.23,P=0.000,tTNF-α=32.26,P=0.000].And those of the observation group improved more significantly than the control group (tIL-1β=17.702,P=0.00,tIL-6=7.107,P=0.00,tTNF-α=21.311,P=0.000).The mortality rate and hospitalization time of the observation group were 18.33% and (10.97±2.92)days,which were significantly lower than those of the control group [36.67%,(13.63±3.26)days;χ2=5.058,P=0.025;t=4.708,P=0.000).Conclusion The use of CRRT in the treatment of severe pancreatitis can improve the vital signs,reduce the inflammation index,improve the serum levels of inflammatory factors and lactic acid,reduce the mortality and hospital stay.

Lifestyle intervention is basic and background treatment for people with type 2 diabetes.Effective lifestyle intervention contributes to better glucose control and delay of diabetic complications.Dietary and exercise interventions as well as lifestyle advice are major components of lifestyle intervention.Dietary intervention focuses on restriction of total caloric intake and balanced nutritional composition,while exercise intervention focuses on exercise mode,frequency,intensity,timing,and duration.This review introduced several lifestyle intervention measures including exercise and dietary interventions as well as lifestyle advice,and discussed their effects on glucose control in people with type 2 diabetes.

Objective:To establish a system for quantitatively measuring alveolar bone density and to test its precision and validity. Methods: With the aid of computer technique, the system measured the average gray level intensity of regions of interest (ROIs) on standardized exposed direct digital periapical radiograph. To correct the variation resulting from exposure condition, an aluminum stepwedge was exposed simultaneously. By referring the image of aluminum stepwedge on each radiograph the equivalent aluminum thickness(EAT)and corrected gray level intensity(CGL)of the ROIs could be calculated as indicators of alveolar bone density. Nineteen specimens containing different amounts of hydroxy-phosphorite were radiographed. The precision of the system was tested by repeatedly measuring 2 of the specimens. The set of specimens was exposed under two different exposure time in order to test the system's validity to correct the gray level difference caused by different exposure time. Results: After repeated measurement of specimens, we found the Relative Standard Deviation(RSD) of EAT and CGL was between 0.83%-2.15%; At the level of 95%, if the difference of EAT between the two ROIs was larger than 0.05 mm or the difference of CGL was larger than 3, the content of hydroxy-phosphorite in them was different; The two sets of data during different exposure time were processed with Wilcoxon Signed Ranks Test, and the result showed effective correction of the variation caused by different exposure time. Conclusion:The precision and validity of the quantitative alveolar bone density measuring system are acceptable. The system can be used to compare alveolar bone density longitudinally and cross-sectionally.
