Objective To compare the effects of vasopressin and adrenaline on cerebral resuscitation in rats. Method Sixty male SD rats were used to set the animal model of cardiac arrest and were randomly (random number) divided into 4 groups (n = 15/group): sham operation group (sham-gro), negative control group (neg-gro), vasopressin group (vas-gro) and adrenaline group (adr-gro). Blood pressure was recorded, and brain tissue samples were obtained. Results There was no significant difference in the recovery rate between vas-gro and adr-gro 30 min after resuscitation (P ＜0.05). The mean blood pressure in vasgro was higher than that in adr-gro within 30 min (1,2, 5, 10, 20, 30 min) after restoration of spontaneous circulation. The measured MDA, SOD and GSH were significantly different (P ＜ 0.05) between each two groups among vas-gro, sham-gro and adr-gro. Conclusions The recovery rate was similar between vasopressin group and adrenaline group during cardiopulmonary resuscitation in rats. However, vasopressin can to maintain the mean arterial pressure at a higher level after resuscitation, which can the increase the cerebral perfusion and reduce brain cell damage.

BACKGROUND: Studies have shown that Maca can enhance immune cel function, improve mitochondrial respiratory chain enzymes, and play a role in anti-oxidation and anti-aging.
OBJECTIVE: To observe Maca effects on kidney mitochondrial respiratory function and anti-aging capabilities in elderly rats after exhausted exercise.
METHODS: 10-month-old elderly rats were intragastrical y administrated Maca powder 5 g/kg, once a day, and did treadmil exercise, 5 days in a week. Rats were randomly divided into control group, Maca group and training group and Maca+training group. At 6 weeks after training, rats in each group did exhausted exercise (35 m/min), and immediately received intraperitoneal injection of 2% sodium pentobarbital. The kidney was obtained, and mitochondria were extracted by differential centrifugation. A spectrophotometer was used to measure mitochondrial respiratory chain activity.
RESULTS AND CONCLUSION: (1) Mitochondrial respiratory chain enzyme and antioxidant enzyme activity: mitochondrial respiratory chain enzyme I-III, superoxide dismutase and glutathione peroxidase activities were higher in the Maca+training group than in the control group, Maca group and training group (P < 0.05 or P < 0.01), but malondialdehyde content was lower (P < 0.05 or P < 0.01). (2) Results suggested that the combination of supplement Maca and incremental exercise can improve mitochondrial respiratory function and delay aging in the kidney of aged rats after exhausted exercise. Moreover, supplemented Maca and incremental exercise have a synergistic effect.

Reviewing the theory of chaos in the field of nonlinear dynamics, this paper summarized theory of chaos and its applications in medical signal processing including electroencephalogram(EEG) signal?electrocardiogram(ECG) signal?electromyogram(EMG) signal, etc. The foreground is reviewed to advance the study and application of nonlinear dynamics theory in biomedical engineering.

Objective To explore the effects of estrogen,sport walking with weight and estrogen plus sport walk on serum lipid,bone metabolism and bone mineral density(BMD) in postmenopausal women.Methods 52 postmenopausal women were divided into the hormone replacement therapy(HRT) group(n=12),sport walking with weight group(Sp group,n=14),HRT + Sp group(n=12) and control group(n=14).HRT group took compound nylestriol,Sp group took sport walking with 5 kg weight and exercise intensity was from 60% to 80% VO2max,HRT+Sp group received two treatments as HRT group and Sp group.The experimental duration consisted of six months.Results The total cholesterol(TC),TC/high density lipoprotein cholesterol(HDL-C),alkaline phosphatase(APL) and urine calcium(Ca)/creatinine(Cr) were markedly lower in three experimental groups than the control group and before experiment(P<0.05 or P<0.01),HDL-C in Sp and HRT+Sp groups were markedly higher than the control group and before experiment(P<0.05),BMD of spine(L2～L4) and left trochanter in three experimental groups were markedly higher than the control group(P<0.01) and before experiment(P<0.0).Conclusion Both estrogen replacement therapy and sport walking with weight effectively improve serum lipid,prevent and reverse osteoporosis induced by menopause in women.

Medical students′ humanistic quality and ability are the key practice elements beyond professional skills. In the perspective of humanization, the cultivation of humanistic ability should guide medical students to es-tablish the human-centered service concept, and break through the narrow limitation of technological view with re-garding disease as the center, and. To integrate the humanism and medicine, the medical humane education should broaden the practical teaching channel and enrich the contents of teaching, based on clarifying the multi-demands.

The paper conducts a case study in Beijing Hospital, introduces the influence of the multi-level publicity platform on hospital visits in 2014 from perspectives of the relationship between patients'gender, age, level of education and the multi-level publicity platform on the basis of needs from patients.It is noted that purposeful and planned publicity is of great significance to the brand influence of hospital.

Objective To discuss the comparability and bias evaluation on the results of serum creatine kinase (CK ) ,aspartate aminotransferase (AST) ,lactate dehydrogenase (LDH) inspection results between the two different kinds of biochemical analysis system .Methods The control quality materials with two concentration were detected respectively for degree of precision ,and the assessment standard was from manufacturer introductions and laboratory setting .Then in accordance with American Clinical and Laboratory Standard Institute(CLSI) document EP9‐A2 ,100 patients serum CK、AST、LDH were detected .Afterwards the relative bias(SE% ) was calculated ,and the comparative analysis bias evaluation was judged according to the half of CLIA′88 allowed total error .Results The variable coefficients mainly conformed to the requirements ,and the experimental results were reliable .The oth‐ers mainly lower than the acceptable limit besides SE% for LDH higher than it .Conclusion It is necessary to execute comparative analysis and bias evaluation to ensure the accuracy and comparability if the same item is detected in two analysis system .

Sepsis is a systemic inflammatory response syndrome caused by infection, which is characterized by multiple inflammatory cytokines and massive reactive oxygen species released.The release of inflammatory cytokines and reactive oxygen species would damage the mitochondrial membrane proteins, mtDNA, etc,which will lead to mitochondrial dysfunction and activate mitochondrial death pathway and even result in multiple organ dysfunction.Exploring the mechanisms of mitochondrial dysfunction in sepsis may provide more effective ways for the treatment of sepsis.

Transducer of ErbB-2.1 (TOB1),as a member of TOB/BTG anti-proliferative proteins family,has the ability of inhibiting cell proliferation and plays an important role in some biological processes,such as cellular proliferation,cycle,growth,apoptosis,metabolism and development via involving in regulating various signaling pathways.Studies have shown that TOB1 is also closely related to tumorigenesis by participating in regulating multiple signaling pathways as to suppress malignant transformation and process.This review will focus on the research development of TOB1 related signaling pathways.
