Objective To investigate the effect of exercise rehabilitation on the rehabilitation of elderly patients with chronic heart failure.Methods One hundred elderly patients with chronic heart failure were randomly divided into study group and control group in equal number using random digits table.The patients in the two groups were given regular exercise and nursing and those of the study group rehabilitation training on the basis of conventional care.Results After 3 months care,the scores on LVESV,LVEDV, LVEF and NYHA in the study group were significantly improved compared to the control group (all P<0.05).After nursing,6 min walking distance of the study group was significantly longer than that of the control group (P<0.05).The rate of readimission in the study group was significantly lower than that of the control group (P<0.05).Conclusions For elderly patients with chronic heart failure, exercise rehabilitation is effective and safe,and can improve the cardiac function.The exercise performance and life quality also can shorten hospitalization time,decrease readmission rate and promote rehabilitation of patients.

Objective To study the influence of Chiamydia trachmatis (CT) and Ureaplasma ure-alyticum (UU) infection on pregnant outcome and neonates. Methods 562 pregnant women were ran-domly selected, their cervical secretion was collected and detected for CT and UU by culture method. Groups were divided according to the results. All of them were followed-up till delivery. Results The in-cidence of infection of group CT、group UU、group CT and UU were 22.1%、28.8% and 3.7%;Compared with negative group,the group with positive result of CT、UU、 CT and UU had significant higher incidence of preterm labor, premature rupture of membranes, low weight infant and neonates pneumonia. Conclusions The infection of CT、UU can result in adverse pregnant outcome, preterm labor, premature rupture of mem-branes, low weight infant and neonate pneumonia.

BACKGROUND: There are plenty of studies of estrogen effects on mammalian osteoblast, but the studies of estrogen effects on bird osteoblast cannot be found. There are many reports about the side effects of letrozole on bone metabolism, but there are no reports about the effect of letrozole on osteoblast.OBJECTIVE: The effects of estrogen and letrozole on the proliferation, cell cycle, estrogen receptor mRNA expression and alkaline phosphatase (ALP) activity of chicken osteoblast in vitro were studied in order to illustrate the mechanism of medullary bone osteogenesis.METHODS: The osteoblasts were harvested from the frontal bone of 15-day SPF chicken embryos by the enzyme digestion, and treated with various mass concentrations of estrogen (0, 5, 10, 20, 100. 200, 400,800, 2 000, 20 000 ng/L) and letrozole (0, 5.10, 25, 50, 100, 250, 500, 1 000, 5 000 μg/L). The proliferation rates of the osteoblast treated with estrogen or letrozole were measured through the MTT method, The ALP activities of osteoblast were measured by the pNPP method. The cell cycle was measured by flow cytometry. The expression of estrogen receptor mRNA was detected using real-time fluorescent quantitative polymerase chain reaction (PCR).RESULTS AND CONCLUSION: The estrogen could promote proliferation of osteoblast in concentration- and time-dependent fashion. Estrogen could increase the expression of estrogen receptor mRNA, impulse cell cycle, and elevate ALP activities.Letrozole could increase the cell population, impulse cell cycle, inhibit estrogen receptor mRNA expression, but letrozole has no effects on ALP synthesis and secretion.

The paper described the practice of contingency nursing management for ICU wards in case of power breakdown in the hospital The SICU wards have developed their power failure contingency plan in which the nurses on duty are divided into Group A,B and C according to their positions and qualifications.Respectively,they take charge of patient safety,coordination and command,and medical aid.We also established the procedure of emergency response for these duties.Training and examination familiarize the medical personnel with the procedure and their duties.Four practices proved that the implementation of the plan reduces risks exposure and improves the satisfaction.With the contingency plan,the nurses in ICU can now take care of critical incidents and avoid nursing risks in ICU efficiently.

Objective To investigate the effects of antioxidant on the fish oil cream and to enhance its stabil-ity.Methods The fish oil cream containing different antioxidant such as vitamin C,vitamin E,EDTA -2Na were prepared.The content of vitamin A with 6 months acceleration test and 12 months after long -term test were deter-mined by HPLC.Results Antioxidants had significant effect on the vitamin A content in fish oil cream,the sequence that antioxidants enhance the stability of the fish oil cream was as follows:VE +Na2 S2 O5 >VC +Na2 S2 O5 >VE +ED-TA -2Na >VC +EDTA -2Na >VE ﹥ Na2 S2 O5 >VC >EDTA -2Na.Conclusion The fish oil cream with antioxi-dant have favorable stability,composite antioxidant is better than single antioxidant.

To review the scientific evidence of system management for lung cancer patients with cancer- related fatigue by the method of literature review and evaluate researchers on authenticity, importance and applicability, in order to improve the nursing quality and the quality of life of them. Interventions of lung cancer patients with cancer- related fatigue mainly includes: non- drug intervention, drug intervention and self- management. The use of intervention measures should be combined with the situation of the patients. however, many of the effectiveness of the intervention measures not sure, need large sample randomized controlled trial verifies the results .

Objective To discuss the influence of motor imagery therapy on the recovery of the stroke patients with aphasia.Methods Sixty cases of stroke patients with aphasia were divided into the treatment group and the control group according to the odd and even of last number.The single number was set into the control group.The double number was given to the treatment group.There were thirty patients in each group.Both groups received the conventional drug treatment and routine care of the Department of Neurology.On this basis,from the second day in hospital,the treatment group received the speech rehabili tation training with motor imagery therapy.Aphasia assessment was done for the two groups on the first day in hospital with CRRCAE.On the first day and after receiving ten-day treatment with motor imagery therapy,the grade of the severity for aphasia of Boston Diagnostic Aphasia Examination (BDAE) was done to assess the severity of aphasia in two groups.The scores of the two groups were compared.Results Before the treatment,there was no significant difference between the two groups.After receiving ten times treatment,both the two groups were improved.Compared with the control group,the treatment group became better.There was statistically significant difference between the two groups.Conclusions For the stroke patients with aphasia,motor imagery therapy has significant effect on their recovery.

Objective: To denvolop HPLC an method for the determination of the content of three saponins in Zhixiao suppositories. Methods: Analysis carriedout was performed on a Kromasil C18 column (4.6 mm×250 mm., 5μm)at 23℃. The mobile phases were methanol and 0.2% phosphoricacid solution in a gradient elution. The flow rate was set at 1.0 mL·min-1 and the ultraviolet detector was operated at 203 nm. Results: The linear ranges of notoginsenoside R1, ginsenoside Rg1 and ginsenoside Rb1 were 0.368～2.76μg,0.676～5.07 μg and 0.812～6.09μg,respectively. The average recoveries of the three saponins were 98.53%, 99.20% and 99.35%, respectively. The RSD (n=5) were 2.11%, 1.88% and 2.38%, respectively. Conclusion: The separation is a good and the results are accurate and reproducible. It can be used for the quality control of Zhixiao suppositories.
