Objective:To evaluate the clinical efficacy and safety of Danhong injections in the adjuvant therapy for angina pecto-ris. Methods:According to a random number table,totally 120 cases of patients with angina pectoris were randomly divided into the observation group and the control group. The control group was treated with the conventional therapy,such as oxygen uptake,anti-in-flammation,expectoration and relieving asthma,and the observation group was treated with Danhong injections(30ml added in 250ml glucose infusions,ivd,qd)additionally. The treatment course was 2 weeks. The hemorheology and blood lipid changes before and af-ter the treatment were recorded,the ECG was analyzed and the clinical symptom improvement was evaluated in the two groups. Re-sults:After the treatment,the hemorheological indices of the two groups were significantly reduced(P<0. 01),and the improvement of the observation group was much better than that of the control group(P<0. 01). After the treatment,the TC,TG and LDL were significantly lower and the HDL was notably higher than those before the treatment in the two groups(P<0. 01),and the improvement of the observation group was significantly better than that in the control group(P<0. 01). The total efficiency of ECG and clinical symptom improvement in the observation group was significantly higher than that in the control group(P<0. 05). Conclusion:Dan-hong injections in the treatment of angina pectoris can significantly improve the hemorheology and blood lipid to enhance the clinical ef-ficacy,which are worthy of promoted application.

Objective To observe the method of mechanical ventilation in the chest compressions during cardiopulmonary resuscitation (CPR),and to explore the influence of the flow pattern selection of square-wave and decelerating-wave on airway pressure of patients. Methods A prospective self-pairing study was conducted. Forty patients undergoing CPR admitted to Department of Emergency of Lishui City Central Hospital from January 2011 to February 2013 were enrolled. Using Respironics Eisprit ventilator,the working mode and parameters of ventilator were set reasonably according to previous research,while the chest compressions was performed in a stable state by the same doctor,. Each patient received different flow,waves,including square-wave and decelerating-wave,and the highest peak airway pressure was recorded as a pair of data when the time-pressure and time-flow waveform were frozen. Two pairs of data by different doctors were collected in each patient. Eighty pairs of data from 40 patients were collected for statistical analysis by paired t test. Results The highest peak airway pressure of decelerating-wave was (38.15± 5.99)cmH2O (1 cmH2O=0.098 kPa),which was (5.71±1.98)cmH2O lower than that of square wave 〔(43.86± 6.68)cmH2O〕with significantly statistical difference(t=22.010,P=0.000). 73.75%patients undergoing square wave with peak airway pressure over 40 cmH2O were found,but only 45.00% patients were found in decelerating-wave. Conclusion Because decelerating-wave used in mechanical ventilation during CPR can obviously reduce the peak airway pressure,the occurrence of barotrauma,and the probability of triggering high pressure ventilator alarm,and improve the compliance of ventilator,so decelerating-wave is more reasonable than square-wave.

Large amount of data including chemical composition and size information of individual particles would be generated in the measurement of aerosol particles using atmospheric aerosol time-of-flight mass spectrometry ( ATOFMS ) . Our home-made ATOFMS was used to measure the indoor individual aerosol particles in real-time for 24 h, and the obtained mass spectrometric data were clustering analysis by self-organizing map ( SOM ) because of its ability of vector quantization and data dimensionality reduction. 20 classification results were got which includedCalcium-Containing,Salt+Secondary particles,Secondary particles,Organic Amines,K+-Rich Organics andSoil particles, etc. Compared with previous mass spectrometric methods, SOM is a natural visualization tool, more classification results can be obtained. This classification information would be useful to assess the response and toxicity of atmospheric aerosol particles and identify the origin of atmospheric aerosol particles.

Objective To study the clinical application of laparoscope combined with gastroscope surgery in patients with gastric stromal tumor. Methods The clinical data of 50 patients with gastric stromal tumor were retrospectively analyzed. Among them 20 cases were treated with traditional laparotomy (laparotomy group), and 30 cases were treated with laparoscope combined with gastroscope surgery (combination group). The intraoperative bleeding, operation time, postoperative recovery time, postoperative hospitalization time and complications were compared between 2 groups. Results One case in combination group received open surgery (3.33%, 1/30), mainly because of obesity, and tumor rupture occurred in 1 case during operation. All specimens of the 2 groups had no tumor residue. There were no statistical differences in tumor diameter and operation time between 2 groups (P>0.05); the intraoperative bleeding, postoperative recovery time and postoperative hospitalization time in combination group were significantly lower than those in laparotomy group:(26.33 ± 14.21) ml vs. (42.57 ± 15.67) ml, (37.96 ± 8.80) h vs. (60.14 ± 13.41) h and (6.42 ± 2.80) d vs. (12.04 ± 4.69) d, and there were statistical differences (P<0.05). The 2 groups had no death, stomach bleeding, anastomotic stenosis and anastomotic leakage. The laparotomy group had postoperative incision fat liquefaction in 3 cases and incision infection in 2 cases, and the combination group had pulmonary infection in 1 case. All were cured after symptomatic treatment. Conclusions Laparoscope combined with gastroscope surgery in the treatment of gastric stromal tumors has a short operation time, less blood loss, faster postoperative gastrointestinal function recovery, shorter hospitalization time, and no major complications. It is a more ideal and minimally invasive surgery.

OBJECTIVE:To observe the efficacy and safety of amiodarone combined with valsartan in the treatment of paroxys-mal atrial fibrillation in elderly patients. METHODS:130 elderly patients with paroxysmal atrial fibrillation were randomly divided into observation and control group. Control group was orally given Amiodarone tablet 0.6 g in the first week,3 times a day,0.4 g in the second week,twice a day,0.2 g in the third week,twice a day;observation group was additionally given valsartan capsule 0.4 g in the first 1-3 day(s),once a day,the dose was increased to 0.8 g if patients showed no hypotension,once a day,and then decreased to 0.4 g if the pressure was lower than 100/60 mm Hg,once a day. The treatment course for both groups was 12 weeks. Clinical efficacy,and left atrium(LA),left ventricular end-diastolic volume(LVEDV),left ventricular systolic volume(LVESV), left ventricular ejection fraction (LVEF),heart rate,cardiothoracic ratio,systolic blood pressure,diastolic blood pressure before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:Total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,LA, LVEDV and LVESV,heart rate,cardiothoracic ratio,systolic blood pressure,diastolic blood pressure in 2 groups were significant-ly lower than before,and observation group was lower than control group,LVEF was significantly higher than before,and observa-tion group was higher than control group,the differences were statistically significant(P<0.05). There was no significant differ-ence in the incidence of adverse reactions(P>0.05). CONCLUSIONS:The efficacy of amiodarone combined with valsartan is more obvious than only amiodarone in the treatment of paroxysmal atrial fibrillation in elderly patients,with similar safety.
