Objective: To observe the therapeutic effect of nicorandil on microvascular angina pectoris (MAP). Methods: A total of 60 MAP patients were randomly divided into nicorandil group (n=30) and routine treatment group (n=30), and they were treated for 12 weeks. Onset times and duration of angina pectoris, changes of related parameters of ECG treadmill exercise test before and after treatment, and total effective rate were compared between two groups. Results: Compared with before treatment, there were significant reductions in onset times and duration of angina pectoris and maximum depression extent of ST segment (P<0.05 or <0.01) and significant increase in total exercise time (P<0.01) after treatment in both groups; compared with routine treatment group, there were significant reductions in onset times of angina pectoris [(10.3±1.6) times/week vs. (9.6±1.7) times/week] and maximum depression of ST segment [(0.8±0.3)mm vs. (0.6±0.2)mm], and significant increase in total exercise time [(7.8±1.4) min vs. (9.4±1.6) min] and total effective rate (73.3% vs. 93.3%) in nicorandil group, P<0.05 or <0.01. Conclusion: Nicorandil possesses significant therapeutic effect on microvascular angina pectoris, and it is worth further study.

The severity of coronary artery diseases is assessed based on morphological and functional stenosis.The study Oil detection of coronary artery diseases based on morphological lesions has unveiled its short comings for evaluation of the seriousness of the disease.Therefore,many research groups diagnose the coronary artery diseases by functional stenosis.From functional aspect,studies of x-ray angiography algorithms for blood flow and velocity measurement are potentially clinically important and are an actively researched subject,which Can accurately diagnose the coronary diseases from functional stenosis aspect.Based on the angiographic images,the article describes formulation and characteristics of existing coronary blood flow and velocity techniques such as tracking and computational methods.Tracking methods can be divided into four classes:bolus transport time algorithms,continuous velocity determination from two-dimensional(time-distance)parametric images,contrast traversal distance algorithms,and droplet tracking algorithms.Computational methods can be divided into six classes:indicator-dilution or Stewart-Hamilton method,first-pass distribution analysis,inverted continuity equation algorithms,inverse mass transport problem approach,optical flow type algorithms,and the fluid continuity method.

Objective To investigate the safety and efficacy of transvaginal hydrolaparoscopic pelvic adhesiolysis (THLPA) treatment in the infertile women.Methods From May 2007 to Sep.2008,30 infertile patients underwent THLPA.The dye-test,hysteroscopy,and dye-test using catheterization of tubal ostium by hysteroscopy were performed at the same time.Pelvic adhesions were scored according to the revised American Fertility Society classification of endometriosis (1985).The adhesions were graded as mild (score 1-9),moderate (10-19),and severe (≥20).Twenty-four cases were in mild adhesions,5 moderate adhesions,and 1 severe adhesion.The duration of the operation and discharge,pelvic adhesions score,tubal patency,complications,and pregnancy rate were investigated.Results (1) THPLA:the majority of pelvic adhesions in all patients were successfully performed adhesiolysis.Only a little filmy adhesions of proximal peritube of 7 tubes and proper ligament of 5 ovaries and cohesive adhesions of 4 ovaries did not underwent surgical lysis.(2) Tubal patency:35 tubes were of proximal occlusion by dye-test,of which 21 (60%,21/35) were unobstructed and 4 (11%,4/35) were partly unobstructed after the dye-test using catheterization of the tubal ostium by hysteroscopy.(3) The duration of operation:the overall operative time were (32±6) minutes in mild adhesion,(52± 6) minutes in moderate adhesion,and 83 minutes in severe adhesion.Of which the time of THLPA were (11±5) minutes in mild adhesion,(35±7)minutes in moderate adhesion,and 62 minutes in severe adhesion,respectively.(4)The duration of discharge:the postoperative discharge time was 120-175 minutes.No complications occurred.(5)The rate of pregnancy:in the (15.8±4.3) months' follow-up,the rate of pregnancy was 45% (13/29),which one patient lost follow-up.Conclusions THLPA is safe,efficacious and not being hospitalized management.When compared with laparoscopy,it is simpler,more economic,and less minimally invasive approach.The appropriate indication of THLPA is to treat filmy,especially mild pelvic adhesions.It could partly avoid transabdominal operative laparoscopy for the infertile women.

Objective To investigate the positive influence of telephone follow-up on primiparas′exclusive breastfeeding during puerperal period. Methods By using convenience sampling method, 90 primiparas were selected who had given birth in the integration ward of our hospital from October to December 2015 as the control group, and 60 primiparas were selected who had given birth in the integration ward of our hospital from December 2015 to January 2016 as the experimental group. For the experimental group, every 2 weeks, a telephone follow-up was executed according to primiparas′parturition time after leaving hospital. For the control group, telephone follow-up was not executed. The influence of periodic telephone follow-up on primiparas′ exclusive breastfeeding was observed. Results The exclusive breastfeeding rate of primiparas in the experimental group was increased as the telephone follow-up was executed. It was up to 91.7%(55/60) 6 weeks since parturition. The exclusive breastfeeding rate of primiparas in the control group was 71.1% (64/90). The difference was significant (χ2=9.28, P<0.01). Conclusions Periodic telephone follow- up according to necessity provides breastfeeding publicity and guidance after parturition, maintaining the continuous education and caring for the primiparas after leaving hospital which efficiently increased the pure breastfeeding rate of primiparas during puerperal period.
