In the present paper,the authors review progresses of researches on the protective effect of acupuncture in resisting acute myocardial ischemia-reperfusion injury in patients and animals from 1) resisting injury of oxygen-derived free radicals,2) reducing intracellular Ca2+ overload,3) relieving dysfunction of vascular endothelial cells of the myocardium,4) regulating immune functional activity and reducing inflammatory injury,5) reducing cardiocyte apoptosis,6) upregulating the expression of heat shock protein(HSP 70) in the myocardium,and 7) regulating activities of multiple cardiovascular protection factors and intracellular signaling pathways.The abovementioned results are mainly obtained from experimental animal studies.For this reason,the authors hold that the coming researches on acupuncture therapy for cardiovascular disorders should pay more attention to its clinical application,for example,controlled blood-pressure decline induced lower perfusion of the coronary artery,cardiac surgery(percutaneous tranluminal coronary angioplasty,intracardiac operation underdirect vision) etc.

Objective To investigate the efficacy and safety of long guidewire exchange technique in performing cerebral angiography via radial artery approach.Methods The clinical data of 257 patients,who received cerebral angiography during the period from June 2014 to May 2016 at Daxing Hospital of Capital Medical University,Beijing,China,were retrospectively analyzed.Among the 257 patients,186 had type Ⅱ or type Ⅲ aortic arch.According to the different looping technologies for Simmons-2 catheter used in the performance of cerebral angiography,these 186 patients were divided into the study group (n=90) and the routine group (n=96).The success rate of radial artery puncturing,the success rate of Simmons-2 catheter looping formation,the success rate of supra-arch arterial catheterization,the time spent for angiography,the radiation exposure time,complications,etc.were recorded.Results The success rate of radial artery puncturing was 100％ in both groups.The success rate of Simmons-2 catheter looping formation in the study group was 97.8％,which was significantly higher than 72.9％ in the routine group (P＜0.05).The success rates of catheterization for the left subclavian artery,left common carotid artery and right carotid artery in the study group were 97.8％,97.8％ and 97.8％ respectively,which were remarkably higher than 72.9％,72.9％ and 72.9％ respectively in the routine group (P＜0.05).No statistically significant difference in the success rates of catheterization for right subclavian artery and for right vertebral artery existed between the two groups (P＞ 0.05).The time spent for angiography in the study group and the routine group was (22.5±9.4) min and (28.3±8.3) min respectively.The radiation exposure time in the study group was (8.9±4.5) min,which was obviously lower than (12.6±6.5) min in the routine group (P=0.017 and P=0.035,respectively).The incidences of complications in the study group and the routine group were 4.4％ and 5.2％ respectively,the difference was not statistically significant (P＞0.05).No severe complications,such as intracranial arterial embolie events,puncture bleeding,arterial occlusion,etc.,occurred in all patients of both groups.Conclusion The use of long guidewire exchange technology can improve the success rate of Simmon-2 catheter looping formation and the success rate of supra-arch arterial catheterization,it can also shorten the time for angiography procedure and reduce the radiation exposure time.This technique is very effective with higher safety.Therefore,this long guidewire exchange technique should be used as a common method for cerebral angiopraphy via radial artery approach in patients with type Ⅱ or type Ⅲ aortic arch.

Objective To assess the value of laparoscopy in the diagnosis and treatment of abdominal emergency during pregnancy.Methods Clinical data of 40 cases of abdominal emergency at 7~17 gestational weeks(mean,13.2 weeks) from June 1997 to October 2004 were retrospectively reviewed.There were 16 cases of uterine with ectopic pregnancy,3 cases of twisted ovary,5 cases of pedicel torsion of ovarian cyst,5 cases of acute cholecystitis,and 11 cases of acute appendicitis.The diagnosis and treatment were conducted under laparoscope. Results The confirmative diagnosis was clarified under laparoscope in all the cases.Except 1 case of conversion to open surgery,the operation was accomplished laparoscopically in all cases. The operation time was 25~70 min(mean,38.2 min).Surgical complications occurred in 1 case.During postoperative follow-up observations,there were 3 cases of threatened abortion,3 cases of inevitable abortion,and 1 case of premature delivery. Conclusions Laparoscopic operation is safe and effective for acute abdominal emergency during early-to-middle pregnancy.

Objective To investigate the clinical effect of caffeine citrate combined with continuous positive airway pressure( CPAP) in the treatment of primary apnea of prematurity.Methods 80 premature infants with primary apnea who received therapy from January 2014 to August 2015 were selected as research subjects.According to ran-dom number table,the infants were divided into two groups equally.Besides conventional treatments,the control group received treatment of caffeine citrate,while the observation group received CPAP and caffeine citrate.Then,the cura-tive efficacy,situation of apnea and adverse reactions were compared.Results The total effective rate between the observation group and the control group had statically significant difference(95.0%vs.77.5%,P<0.05) .Compared with the control group,the observation group had statistically less seizure frequency,shorter duration of seizure and disappearance time of symptoms(all P<0.05).During the treatment,incidence rates of tachycardia,dysphoria and electrolyte disturbance in the observation group were statistically lower than those in the control group (all P<0.05), while the incidence of feeding intolerance in the two groups had no statistically significant difference ( P >0 .0 5 ) . Conclusion Caffeine citrate in combination with CPAP is effective for primary apnea of prematurity,which can sig-nificantly increase curative efficacy,lessen seizure frequency of apnea,shorten duration of seizure and disappearance time of symptoms with less adverse reactions.

Objective To investigate the single nucleotide polymorphism of 5,10-methylenetetrahy-drofolate reduetase gene and its association with the treatment of methotrexate in rheumatoid arthritis (RA).Methods A total of 184 patients with RA were divided into methotrexate (MTX) treatment group, MTX+other DMARDs treatment group, and treatment with other DMARDs but not MTX group. The clinical and laboratory data were evaluated before treatment and 24 weeks later. Efficacy and toxieities of each medication were also analyzed. Real-time fluorescent quantitative PCR was conducted to test gene mutations in RA patients and 100 healthy controls. Results There was no significant difference in the frenqueney of 677CC,CT, "IT and 1298AA, AC, CC between RA patients and the healthy controls. There was significant difference in the frenqueney of 677CC, CT, Tr between RA patients with cardiovascular eomplieations and the healthy controls. In the MTX treatment group, there was significant difference in the frenqueney of 1298AC, CC between the group in which MTX was effective and the other groups in which MTX was not effective, the occurrence rate of side effects of MTX in the patients with 677TT was higher than those without mutation(CC).In MTX+other DMARDs group, the occurrence rate of side effects of MTX in the patients with 677TT and CT was higher than that without mutation (CC). Conclusion There is no relationship between the pathogenesis of RA and the 677C/T, 1298A/C mutation of MTHFR gene. MTHFR gene 677C/T mutation is probably one of the genetic risk factors for cardiovascular complications of RA patients and the side effects of MTX. MTHFR gene 1298A/C allel is associated with the efficacy of MTX.
