Objective To study the electrophysiologic characteristics of atrial-ventricular reentrant tachycardia(AVRT)characterized by paroxysmal occurrence that slow atrioventricular accessory pathway participatesin.Methods Twenty-one cases were chosen from patients receiring radiofrequency ablation therapy in Peking University People's Hospital from July in 1999 to January of 2005.The patients with slow atrioventricular accessory pathways diagnosed correctly were divided into two groups with paroxysmal tachycardia and permanent tachycardia in terms of the occurrent frequence of AVRT.The electrophysiologic features of AVRT of two groups were contrastively analyzed.Results Compared with the group of permanent AVRT,it was found that antidromic refractory period of slow atrioventricular accessory pathways was longer[(359?46)ms vs (318?31)ms,P

Objective To evaluate the safety and efficacy of distal protection device(GuardWire PlusTM) during high risk PCI in patients with acute myocardial infarction(AMI).Methods Seventy-two patients with AMI admitted from September 2004 to May 2006 who received PCI were categotized into the GuardWire PlusTM group(GW group,n=38) and the conventional guidewire group(NGW group,n=34) according to the device used.The basic clinical characteristics,angiographic results,degree ST of resolution and changes in serum CK-MB and cTnI levels were compared.LVEF was measured by echocardiography at discharge and again at 3 months after PCI.Results All the distal protection deveices were applied successfully in the GW group.A greater percentage of patients in the GW group had post procedural ST-segment resolution ≥50% compared with the NGW group(68.4% vs 41.2%,P

OBJECTIVE: To study the regular pattern and characteristics of adverse drug reactions(ADR) in our hospital.METHDOS: 93 ADR cases collected from Jan.1,2006 to Dec.31,2006 in our hospital were analyzed statistically in respect of drug categories,Sex and age distribution,routes of administration,organs and systems involved and clinical manifestations etc.RESULTS: Of the 93 ADR cases,the patients aged above 60 showed the highest proportion(47.3%);31.2% were induced by anti-infective drugs;69.9% were induced through intravenous way;and damages of skin and its appendants were the most common manifestations(35.5%).CONCLUSION: Anti-infective drugs should be used rationally to avoid or reduce the occurrence of ADR.

Objective To study changes of neuroendocrine in patients with ST segment elevation acute myocardial infarction (STEMI) after using distal protection device (GuardWire PlusTM). Method Seventy patients with STEMI received percutaneous coronary intervention (PCI) in Municipal Hospital Qingdao, during September 2004 to December 2006. They were randomdy (random numbs) enrolled in this prospective and control study. All the patients were divided into 2 groups: the distal protection device group (GW) and the non-distal protection device group (NGW).The inclusion criteria were:onset within 6 hours, chest pain more than 30 minutes without response to nitroglycerin, two or more adjacent ST segnents elevated over 0.2 mv,the proximal or middle diameter of infarction artery over 3 mm, and the increased plasma creatine kinase. The exclusion criteria were fluctuation in hemodynamics, severe heart failure, arteriopathy of left main coronary artery, mechanical complications of acute myocardial infarction and multi-vessel disease scheduled for coronary artery bypass. The plasma levels of endothelin(ET) , plasma renin activity (PRA),aldosterone (ALD),angiotensin Ⅱ (Ang Ⅱ), norepinephrine (NE) and epinephrine (E) were measured on the day of operation and on the 1st,2nd,3rd and 5th day after operation, respectively. The t-test was used to compare those neuroendocrine elements between two groups. Results There were no differences in plasma levels of all the neuroendocrine elements between two groups before operation. Compared with the NGW group, the levels of neuroendocrine elements in the plasma rapidly decreased in the GW group at 1 d after the operation ( P ＜ 0.05). Conclusions In patients with ST segment elevation acute myocardial infarction, the distal protection device can decrease the changes in neuroendocrine.

The paper reviewed clinical reports on the treatment of hypermenorrhea, menostaxis, and uterine bleeding with Ancong Decoction and modified Ancong Decoction. Although there were few reports concerned with clinical usage, Ancong Decoction has sound therapeutic effects, with more than 90% effective rate.

BACKGROUND:Peripheral nerve defect due to limb dysfunction has always been the difficulty faced by the medical profession. Ideal materials and processing technology for constructing a tissue engineering scaffold targeting peripheral nerve repair are stil in research stage. OBJECTIVE:To review the research progress in peripheral nerve repair using col agen/silk fibroin nerve conduits. METHODS:In this paper, the first author retrieved the PubMed and CNKI from 2003 to 2016 to search articles regarding methods of constructing artificial nerve scaffolds and selection of raw materials. Data from these articles were col ected, summarized and analyzed. RESULTS AND CONCLUSION:Forty-six articles were included for final analysis. Col agen and its degradation products trigger no inflammatory response in the host because of high biocompatibility and biodegradability. However, its use is largely limited by its rapid degradation and poor physical performance. Silk fibroin has a high flexibility and biocompatibility, and exhibits a slow degradation in vivo. As a rapid prototyping technique, three-dimensional printing can print various forms of scaffolds within a short time, characterized as high-quality pore structure and large-scale production. Given these, the col agen/silk fibroin nerve conduit prepared using the three-dimensional printing technology can maintain the biocompatibility and even improve the mechanical properties of the raw materials. Until now, more investigations on nerve repair using col agen or silk fibroin have been done, and we have never stopped improving the production process of these scaffolds. Therefore, the col agen/silk fibroin scaffold prepared using the three-dimensional printing technology is expected to become the main candidate for the repair of peripheral nerve defects.

Objective To investigate the clinical efficacy of Yang’s pricking-cupping bloodletting in treating cervical spondylotic radiculopathy and its effect on trapezius tension.Methods Seventy-eight patients with cervical spondylotic radiculopathy were randomly allocated to treatment and control groups, 39 cases each. The treatment group received pricking-cupping bloodletting and the control group, conventional acupuncture plus cupping. The nerve function was scored, the visual analogue scale (VAS) score was recorded and trapezius tension was measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There were statistically significant pre-/post-treatment differences in the nerve function score, the VAS score and trapezius tension in the two groups (P<0.01). There were statistically significant post-treatment differences in the VAS score and trapezius tension between the treatment and control groups (P<0.05). The total efficacy rate was 94.9% in the treatment group and 89.7% in the control group. There was a statistically significant difference in theclinical therapeutic effect between the two groups (P>0.05).Conclusions Yang’s pricking-cupping bloodletting can effectively improve pain symptoms and trapezius tension in patients with cervical spondylotic radiculopathy.

Objective To optimize extraction technology of flavonesingredients from Herba Epimedii by uniform design. Methods Ultraviolet spectrophotometry was adopted to determine the content of total flavonoids. Content of epimedin A, epimedin B,epimedin C,icariin and baohuosideⅠ were determined by HPLC. U10?( 108 ) uniform design was used to conduct the multiple comprehensive evaluation of six ingredients and comprehensively analyze the influence of the concentration and amount of ethanol, extracting time on extraction of flavonesin gredients from Herba Epimedii. Results The uniform design experiment showed that 15-fold weight of 60% ethanol,extracting 2 times and each time with 165 min were the optimum extraction condition. Conclusion The method is easy and reasonable to handle,has stable and reliable results,and good repeatability and feasibility.It can be applied in industrial production.
