Objective To observe the influence of parturients hemodynamics and curative effect of preventing hypotension syndrome by using hypotension syndrome prevention bracket in cesarean section with spinal anesthesia.Methods One hundred parturients of cesarean section,ASA grade Ⅰ-Ⅱ,were divided into two groups according to whether the use of hypotension syndrome prevention bracket with 50 cases each:observation group and control group.Control group in anesthesia after the success of the surgery made bed left tilt 15°,and observation group in anesthesia after the success immediate used hypotension syndrome prevention bracket.In the two groups,the change of systolic blood pressure (SBP),diastolic blood pressure (DBP),heart rate (HR),mean arterial pressure (MAP),the incidences of hypotension syndrome and nausea and vomiting during and after operation,and anesthesia to uterine incision time and anesthesia time were observed.Results There was no significant difference in anesthesia to uterine incision time,anesthesia time,intraoperative infusion quantity,amount of bleeding between the two groups (P ＞ 0.05).The incidences of hypotension syndrome and nausea and vomiting in observation group were 8.00％ (4/50) and 4.00％ (2/50),in control group were 42.00％ (21/50) and 24.00％ (12/50),there were significant differences between the two groups (P ＜ 0.05).The observation group at 5 min after anesthesia SBP,DBP,MAP were (106.12 ± 12.91),(57.26 ± 11.43),(73.57 ± 11.03) mm Hg (1 mm Hg =0.133 kPa),and the control group were (95.44 ± 19.53),(50.15 ± 15.53),(66.36 ± 15.64) mm Hg,there were significant differences between the two groups (P ＜ 0.05).The observation group at 10 min after anesthesia SBP,DBP,MAP were (104.35 ± 11.86),(55.92 ± 10.81),(72.54 ± 10.37) mm Hg,the control group were (102.31 ± 15.48),(55.12 ± 11.89),(70.72 ± 11.33) mm Hg,there were significant differences between the two groups (P＜ 0.05).The observation group at 3 min after the delivery of fetus and the end of operation DBP,MAP were (54.13 ± 9.14) and (62.63 ± 8.61) mm Hg,(68.13 ± 10.40) and (80.88 ± 9.05) mm Hg,the control group were (49.24 ± 11.55) and (58.04 ± 11.67) mm Hg,(70.57 ± 8.58) and (75.35 ± 10.41) mm Hg,there were significant differences between the two groups (P ＜ 0.05).Conclusion Cesarean section parturients using hypotension syndrome prevention bracket can reduce the occurrence of hypotension syndrome,which can help to maintain the stability of parturients hemodynamics,it is worth of clinical promotion.

ObjectiveTo find the mechanism of Heshouwuyin(HSWY) in anti-aging, so as to provide theoretical and experiment evidence for the application of HSWY. Methods50 eight-week female SD rats ( SPF degree)were used in this study. The rats were randomly divided into 5 groups:normal control group, 10 rats; model group,10 rats; HSWY anti-aging group, including low, middle and high dose group,10 rats in each group. The sub-acutely aging rats were made by ip injection of D-galactose for 60 days continually. The rats in HSWY groups were administered with various doses of intragastric HSWYduring D-galactose injection. The parameters of ovary levels of SOD,GSH-PX, TAOC were detected. ResultsThe MDA in ovaries of model rats was significantly higher than that of negative control group;while the SOD, GSH-PX, TAOC of model rats were significantly lower than negative control group.The MDA content in ovaries after taking HSWY was significantly lower than that of model rats; while the SOD, GSHPX,TAOC of the taking HSWY rats was significantly higher than that of model rats. ConclusionThe HSWY could increase antioxida tive activity of rat ovaries to stay D-galactose induced consenescence.

Based on the peak value of power spectral density (PPSD) and corresponding frequency (CF), an approach that performs electroencephalogram (EEG) feature extraction during imaginary right and left hand movements was proposed. The data were gained from brain computer interface competition in 2003 provided by Graz University of Technology. The EEG signals between 8-16 Hz were decomposed by db3 wavelet packet at three levels. The PPSD and CF of electrodes C3 and C4 were defined as the EEG feature vectors and calculated respectively. The left and right hand motor imaginary tasks were distinguished by the time-variable linear classifier. The proposed method was applied to the test data for 140 trials. The satisfactory results were obtained with the highest classification accuracy 89.29%. The maximum mutual information was 0.622 8 bit, and the signal-to-noise ratio (SNR) was 1.371 3. The PPSD and its CF on electrodes C3 and C4 between 8 and 16 Hz were coincident with event-related desynchronization (ERD) and event-related synchronization (ERS). This method is simple, quick, and promising for on-line brain computer interface system.

Objective To observe the effect of comfort care on psychological status and life quality of patients undergoing interventional treatment of coronary heart disease. Methods 86 cases patients with coronary heart disease were randomly classified into the observation group and the control group with 43 cases in each group. The observation group was treated with comfort care and the control group was treated with normal nursing. The psychological status and life quality between the two groups were compared. Results Compared with pre-nursing, not only physiological function, independence, spiritual beliefs, social relations and quality of life but also SAS and SDS in the observation group were significantly improved after nursing. However, there were no significant differences in the control group. Moreover, the scores of life quality and anxiety and depression were significantly better than those in the control group. Conclusions Comfort care on patients with coronary heart disease can improve anxiety and depression status, servicing satisfaction and life quality of patients.

Objective To observe the effect of nursing intervention on anxiety and depression status and life quality of patients with chronic heart failure (CHF). Methods 124 cases patients with CHF were randomly classified into the observation group and the control group with 62 cases in each group.The observation group was treated with nursing intervention,the control group was treated with routine nursing.The anxiety and depression status and life quality between the two groups were compared. Results Compared with pre-nursing,not only SAS and SDS score but also physical function,role function,emotional function,social function and quality of life in the observation group were significantly improved after nursing.However,there were no significant differences in the control group.Moreover,the scores of anxiety and depression and life quality were significantly better than those in the control group. Conclusions Nursing intervention for patients with CHF can improve anxiety and depression status and life quality of patients.

Objective To explore the status quo of knowledge,belief,and practice of anticoagulationrelated self-management in rehabilitation period for patients with haeat valves replacement.Methods Van Manen's hermeneutic phenomenology was used as qualitative research method.Twenty patients who had undergone heart valves replacement operation were selected and interviewed.The results of interview were analyzed with category analysis.Results After repeated self-examination,comparison,and summery,four themes were refined,including patients lack anticoagulation-related knowledge and skills in rehabilitation period,the levels of patients' attitudes and beliefs varied greatly,patients' compliance of self-management behavior and taking medicine was low,there were limited channels to get anticoagulation-related information in rehabilitation period.Conclusions More attention should be paid to patients for anticoagulation management after valve replacement operation,especially to those of low literacy,older age,and rural area.Nurses should implement the specific health education about anticoagulation management to patients during discharge guide and following-up period to minimize complications,promote the survival rate,and improve their quality of life.

Objective To investigate postpartum blood lose of cesarean section (CS) within 24 hrs in Nanjing area Methods Stratified samples were collected from hospitals of different levels and located at different districts The amount of postpartum blood loss was precisely measured by methods of weight, volume and area Results There were 1 125 CS in a total of 4 171 deliveries The main indications for CS were cephalo pelvic disproportion, fetal distress, breech presentation, and there was 10 4% of CS without definite causes The average amount of blood loss was 520 ml in CS, which was far more than that in vaginal delivery ( n = 3 046) If postpartum hemorrhage (PPH) is defined as blood lose of 500ml or more, the incidence of PPH was 53 7%; if it is defined as 700 ml, the incidence was 19 8% Conclusions Cesarean section is an important cause of PPH, and CS without proper indication should be avoided It seems reasonable to defined the criteria of PPH in CS as 700 ml or more
