Objective To investigate the short and longterm effect of the treatment on acute coronary syndrome(ACS) with percutaneous coronary angioplasty and stenting.Methods 65 patients suffering from ACS were treated with angiography to illuminate the features of lesions and proceeded with percutaneous coronary angioplasty and stenting when the angina was not completed controlled with internal medicine.All patients were treated with a new anti-thrombotic regimen,including aspirin,ticlopidine or clopidogrel, and low-molecular-weight heparin.Results The rates of success for patients and lesions were 96.9% and 82.7% respectively.One patient died without myocardial infarction or emergency bypass surgery.56 patients had no symptom of angina after procedure,and 5 patients had non-typical chest pain which disappeared within 2~3 days.During the 3~54 month follow-up,one patient died,one patient developed myocardial infarction and 4 patients underwent target vessel revascularization(repeated angioplasty 2 and bypass surgery 2).Conclusions With the widespread use of aspirin-ticlopidine-low molecular heparin regimen,ACS patients can undergo PTCA and stenting with high success rate,excellent immediate efficacy and long-term efficacy.

Objective To investigate the serum of soluble CD40 ligand(sCD40L) in coronary heart disease and its relationship with serum lipid levels and the extent of coronary stenosis,whether upregulation of CD40L system is related to stability of atherosclerotic plaque in patients with acute coronary syndrome.Methods Enzyme-linked immunosorbent assay(ELISA) was used to measure the level of sCD40L in 64 patients with coronary heart disease(18 with acute myocardial infarction,19 with unstable angina pectoris and the other 27 with stable angina pectoris) and 20 matched healthy controls.Coronary stenosis of 29 patients were assessed by angiographic coronary stenosis morphology.Results sCD40L level was significantly higher in patients with acute coronary syndrome(ACS)((19.8?3.0)、(19.6?4.3)ng/mL in acute myocardial infarction and unstable angina pectoris group,respectively)than that of those with stable coronary heart disease and that of controls((8.3?3.2)ng/mL and(2.6?1.9)ng/mL,respectively P

Objective To evaluate the efficiency of transcatheter closure of PDA using domestic occluder device.Methods Thirteen two patients(male 11,female 21) with PDA were treated by transcatheter closure of PDA with domestic occluder device. The mean age of patients was 14.4?9.8 years (ranged from 1.8 to 39 years old). PDA were shown by transethroracic echocardiography (TTE) before interventions. Each case was treated with domestic occluder device through the percutaneous procedure under fluoroscopy and TTE. After the procedure,TTE were performed immediately to find whether there any residual shunt remained. Transthoracic echocardiography (TTE) and X-ray examination were done 24-hour, 1-month, 3-month and 6-month after the procedure to evaluate the efficiency.Results The success rate of placement of domestic occluder was 100%. Thoracic angiography showed that 18 patients had complete immediate closure and one had a small residual shunt after the operation. Residual shunt was found in four case after the operation. X-ray examination and TTE showed that both pulmonary vascularity and heart size were improved.Conclusions Transcatheter closure of PDA using domestic occluder device is an efficient nonsurgical method for patients of any age group. The operation is simple and safe with a high success rate of placement and a good occlusion effect. The long-term follow-up remains to be studied.

Objective To evaluate the diagnostic value of H-FABP、cTnI and CK-MB for early detection of acute myocardial infarction(AMI).Methods 20 New-Zealand rabbits were randomly divided into 2 groups:surgery group(MI group,n=12) and sham surgery group(control group,n=8).MI group was opened the chests and the anterior descending branches of the left coronary arteries(LAD) were ligated;in sham surgery group the sutures were passed under the LADs without ligation.Blood sampled before surgery and 1,2,3,4,6,8,10 and 24 h after surgery.H-FABP,cTnI and CK-MB were measured by ELISA respectively at the same time.Results The plasma concentrations of H-FABP 1 hour after surgery showed statistical difference between MI group and sham surgery group(P

Background:Non-variceal vascular originated gastrointestinal bleeding has been attracted more and more attention in clinical practice. Because of the poor efficacy of conventional drug therapy and the high rebleeding rate,endoscopic therapy or interventional therapy have become the first choice. Aims:To investigate the therapeutic value of endoscopic therapy and interventional therapy in non-variceal vascular originated gastrointestinal bleeding. Methods:Retrospective analysis was performed in 77 patients with non-variceal vascular originated gastrointestinal bleeding who underwent endoscopic therapy or interventional therapy from January 2010 to May 2016 at Daping Hospital of the Third Military Medical University. The therapeutic efficacy of the two therapies was compared. Results:In 77 patients,48 patients received endoscopic therapy and 29 patients received interventional therapy. Compared with interventional therapy group, hemoglobin was significantly higher (P = 0. 007)and Blatchford score was significantly lower in endoscopic therapy group (P = 0. 021). Stomach lesion was found in 22 patients,25 in duodenum,18 in small intestine,9 in colon and 3 in rectum. Angiodysplasia lesion was found in 35 patients,ulcer combined with angiodysplasia in 26 patients,arterial rupture in 13 patients,and angiotelectasis in 3 patients. Rebleeding occurred in 7 patients underwent endoscopic therapy within 72 hours. No rebleeding was found in patients underwent interventional therapy,however,1 patients died from pulmonary embolism. Conclusions:Most patients with upper gastrointestinal angiodysplasia can benefit from endoscopic therapy. Surgery may be a better choice for those with more severe mucosal damage and rebleeding within 72 hours after treatment. Interventional treatment may be a first choice for those who have bleeding from small intestinal angiodysplasia,lower hemoglobin and a higher Blatchford score.

Objective To explore the clinical characters,treatment and prognosis of gastrointestinal Dieulafoy lesion in China.Methods Dieulafoy was used as search term,the literatures about Chinese patients with Dieulafoy lesions from January 1998 to October 2016 were retrieved in the Chinese literature library including China National Knowledge Infrastructure,VIP network,Wanfang database and China Biology Medicine disc,and a total of 515 literatures,5 145 patients were enrolled and analyzed.The gender,age,geographical distribution,location of the lesion,treatment and prognosis of the disease were summarized.Results Among the 5 145 patients (male 3 959,female 1 186) with Dieulafoy disease,the ratio of male to female was 3.34∶1.00.The age was from 3 to 95 years,and mean age was 51 years.The lesion location was mainly in stomach (88.82％,4 570/5 145) and second was small intestine (8.28％,426/5 145).In stomach,the lesions were mainly located in gastric corpus,fundus and cardia.The small intestinal Dieulafoy lesions were mainly located in duodenum.The main manifests were sudden hematemesis,melena,and hematochezia.The treatments mainly was endoscopic treatment (72.56％,3 733/5 145),and second was surgery (25.27％,1 300/5 145).Among the5 145 patients withDieulafoy disease,5 099 patients (99.11％) were cured and 46 patients (0.89％) died.The proportions of endoscopic treatment,interventional therapy and first endoscopic treatment within 24 hours in tertiary hospitals were all higher than those of nontertiary (all P＜0.01).The cure rate of tertiary hospitals (99.22％,3 674/3 793) was significantly higher than that of nontertiary hosptials (98.54％,1 421/1 442) (x2 =0.89,P＜0.05) and the mortality was significantly lower than that of nontertiary hospitals (P＜ 0.05).Conclusions The male is more susceptible to Dieulafoy lesion which occurred at any age than the female in China.The predilection sites of Dieulafoy lesion were stomach and duodenum.The primary treatments were endoscopic treatment and surgery,and the disease usually had a good prognosis.

Objective: To analyze the clinical features of perianal condyloma acuminatum in HIV infected men who have sex with men (MSM) and assess the effects of combined treatment of microwave and photodynamic therapy. Methods: Clinical and laboratory data of 260 male patients with perianal condyloma acuminatum were collected and microwave combined with photodynamic therapy was applied on them. Results: The majority of the patients with perianal condyloma acuminatum were young people (243/260). Warts were mainly located in the anus or from the outside to inside of the anus (245/260). Among them, the proportion of warts position of extraanal in HIV-infected group (8/220) was lower than that of non-HIV-infected group (7/40). HPV types 11 (70/118), 6 (44/118) and 16 (40/118) were the most common types of HPV infection. People with HIV infection were more likely to develop high-risk, mixed types HPV infection and multiple HPV infection than those without HIV infection. More than half of the patients (146/260) needed only 1-3 sessions of photodynamic treatments. There was no significant difference in the times of photodynamic treatments and the numbers of photosensitizers required between the HIV-infected and non-HIV-infected groups. The recurrence rate of HIV-infected group (13.6%, 30/220) was also similar to that of non-HIV-infected group (15.0%, 6/40), but far lower than those who underwent microwave therapy alone (45%, 18/40). Conclusions The combination therapy significantly reduced the recurrence rate of perianal condyloma acuminatum in HIV infected MSM.

Aspiration is the entry of oropharyngeal or gastric contents into the lower respiratory tract through the glottis, a common and important cause of death in elderly patients due to lung infections.However, a lack of accurate and rapid clinical methods for the diagnosis of aspiration leads to misdiagnosis, missed diagnosis or delayed diagnosis of aspiration, especially aspiration pneumonia.In recent years, with further research into the mechanisms of aspiration syndromes, multiple aspiration biomarkers with potential and clinical translational value have been found, and may help early detection of aspiration and have important and practical significance for elderly health.Therefore, this article reviews aspiration biomarkers such as pepsin, α-amylase, bile acid and other potential biomarkers as well as current relevant research, detection methods, their clinical value and prospects concerning challenges and directions of innovation in future research.

Objective: To investigate the role of PI3K/Akt signaling pathway in ischemic rats underwent cardiac shock therapy. Methods: Adult male Sprague Dawley (SD) rats weighing 220-250 g were used to establish a heart failure model by ligation of the left anterior descending coronary artery. Rat models were defined by echocardiographic assessment at 4 weeks post operation and heart failure rats were randomly divided into 4 groups,namely heart failure group (HF group, 9 cases),heart failure+cardiac shock waves therapy group (HF+CSWT group, 9 cases),heart failure+inhibitor(HF+LY294002 group, 9 cases),heart failure+cardiac shock waves therapy group+inhibitor (HF+CSWT+LY294002 group, 9 cases),and another 9 sham-operated SD rats served as control group (sham group, 9 cases). At 8 weeks postoperation, echocardiography was used to evaluate cardiac function in each group,myocardial infarct size was measured by TTC staining,the apoptotic index of rats cardiomyocytes were detected by TUNEL method,the myocardial mRNA expression of apoptosis-related factor was detected by real-time quantitative PCR, the protein expression levels of PI3K/Akt signaling pathway and apoptosis-related pathways were detected by Western blot. Results: (1) Eight weeks after operation, left ventricular end diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) were significantly lower in HF+CSWT group than in HF group (all P<0.05), left ventricular ejection fraction (LVEF) and left ventricular shortening rate (LVFS) were significantly higher in HF+CSWT group than in HF group (all P<0.05),LVEF was significantly lower in the HF+ CSWT+ LY294002 group than in HF+ CSWT group (P<0.05). (2) Myocardial infarct size was significantly lower in the HF+ CSWT group than in HF group ((5.57 ± 0.51)% vs. (25.56 ± 0.56)%, P<0.05), which was significantly higher in the HF+CSWT+LY294002 group than in HF+CSWT group ((12.90±2.34)% vs. (5.57±0.51)%,P<0.05). (3) The cardiomyocyte apoptotic index was significantly lower in the HF+CSWT group than in the HF group ((30.25±6.12)% vs. (53.85±9.89)%,P<0.05), which was significantly higher in the HF+CSWT+LY294002 group than in the HF+CSWT group ((46.12±3.42)% vs.(30.25±6.12)%,P<0.05). (4) The myocardial mRNA expression of Bcl-2 was significantly higher, while myocardial mRNA Bax and Caspase-3 expression were significantly lower in HF+CSWT group than in HF group and HF+CSWT+LY294002 group (all P<0.05). (5) The expression levels of p-Akt, Bcl-2 and pro-Caspase-3 in myocardial tissue were significantly higher in the HF+CSWT group than in the HF group and HF+CSWT+LY294002 group (all P<0.05), which were significantly lower in the HF+LY294002 group than in the HF and HF+CSWT+LY294002 groups (all P<0.05). Myocardial Bax protein expression was significantly lower in the HF+CSWT group than in the HF group and the HF+CSWT+LY294002 group (all P<0.05), which was significantly higher in the HF+LY294002 group than in the HF group (P<0.05). Conclusion CSWT improves cardiac function and inhibits cardiomyocyte apoptosis through PI3K/Akt signaling pathways in this rat HF model.

Non-exosomal non-coding RNAs (non-exo-ncRNAs) and exosomal ncRNAs (exo-ncRNAs) have been associated with the pathological development of myocardial infarction (MI). Accordingly, this analytical review provides an overview of current MI studies on the role of plasma non-exo/exo-ncRNAs. We summarize the features and crucial roles of ncRNAs and reveal their novel biological correlations via bioinformatics analysis. The following contributions are made: (1) we comprehensively describe the expression profile, competing endogenous RNA (ceRNA) network, and "pre-necrotic" biomarkers of non-exo/exo-ncRNAs for MI; (2) functional enrichment analysis indicates that the target genes of ncRNAs are enriched in the regulation of apoptotic signaling pathway and cellular response to chemical stress, etc.; (3) we propose an updated and comprehensive view on the mechanisms, pathophysiology, and biomarker roles of non-exo/exo-ncRNAs in MI, thereby providing a theoretical basis for the clinical management of MI.
