1.Current status and progress of fully covered self-expandable metal stents in the treatment of benign biliary and pancreatic ductal strictures
Chinese Journal of Digestive Surgery 2014;13(6):493-496
Though the primary data on fully covered self-expandable metal stents (FCSEMS) in the treatment of benign biliary strictures caused by chronic pancreatitis and anastomotic stricture following orthotopic liver transplantation is encouraging,the risks including stent translocation,biliary infection,pancreatitis and inability to remove stents should be considered before replacing plastic stents with FCSEMS for the first-line treatment of benign biliary strictures in routine practice.FCSEMS is effective in treating benign pancreatic ductal strictures,but it is also associated with a high rate of stent translocation.To overcome this problem,FCSEMS with better conformability and flared ends need to be designed.There is a theorectial risk of pancreatic ductal infection caused by the blockage of side branches of the pancreas by covering membrane of the stents.However,no such complication was reported.Given the uncertain long-term efficacy and safety of FCSEMS for benign pancreatic ductal strictures,their use may be reserved for the management of retractory,symptomatic benign strictures only in selected groups of patients.

Journal of Medical Research 2009;38(8):60-61
Objective To investigate the occurence of glomus tumor and investigate its diagnosis and treatment. Methods 13 cases of glomus tumors were analyzed retrospectively. There were 9 females and 4 males. All 13 cases were surgically treated under megaloscpe. Results All the cases were testified as glomua tumors by pathology. There was no recurrence during the follow up of 6 months to 1 year. All the patients were symptom free. Conclusion Glomus tumor has specific features on clinical presentation. Mierosurgieal excision under megaloscpe is fill elective method.
3.Research advances in monitoring platelet function in patients with coronary artery disease
Chinese Journal of Laboratory Medicine 2013;(6):489-493
Antiplatelet therapy and stent implantation have been the dominant treatment to reduce the mortality of patients with coronary artery disease.Recently,studies have showed that adverse cardiac events still occur in part of patients with coronary artery disease after the antiplatelet treatment with aspirin and/or clopidogrel.Thus,resistance to aspirin and clopidogrel has attracted increasing attention.It will be great benefit to these patients who were identified resistance and made tailoring antiplatelet therapy So far many platelet function tests has been used in clinical to monitor the reaction of the antiplatelet drugs for prevention and treatment of thrombosis in patients with coronary artery disease.These monitoring tests may be chosen based on different antiplatelet drugs including aspirin,clopidogrel and GP Ⅱ b/Ⅲ a antagonist.The results of antiplatelet drug resistance may be different due to different platelet function methods,thus the related clinical adverse events needs further verification.
4.Suture anchors for the repair of deltoid ligament injury:restore the stability of ankle joint
Chinese Journal of Tissue Engineering Research 2015;(22):3565-3570
BACKGROUND:Ankle fractures combined with deltoid ligament injury are not uncommon in clinical practice, prone to misdiagnosis and missed diagnosis, resulting in ankle instability, chronic pain and traumatic arthritis. In recent years, because of the research and development of anatomy and biomechanical characteristics of deltoid ligament, the treatment and surgical methods of ankle fracture combined with deltoid ligament injury have progress and development, but it remains controversial. OBJECTIVE:To evaluate the clinical effect of suture anchor repair in the treatment of ankle fracture combined with deltoid ligament injury. METHODS: Twenty-seven patients with ankle fracture combined with deltoid ligament injury were selected between January 2010 and January 2013. The lateral maleolus and posterior maleolus fracture patients were treated with open reduction and internal fixation, and al the deltoid ligament injury patients were treated with anchor repair. The tibiofibular syndesmosis isolated patients received internal fixation with a cancelous bone screw. RESULTS AND CONCLUSION:Al 27 patients were folowed-up for 11-35 months, averagely 23 months. The evaluation according to the American Orthopaedic Foot and Ankle Society score system showed that the excelent and good rate was 74.1%. The results indicate that anchor could perfectly restore the stability of ankle joint.

Objective To investigate the clinical features of young female patients with acute myocardial infarction (AMI) who were referred to Peking Union Medical College Hospital. Methods A total of 24 consecutive AMI female patients (age≤44 years) who underwent coronary angiography were retrospectively retrieved from the database, and 70 AMI patients whose age ≥ 65 years and who also underwent coronary angiography were enrolled as a control (elderly) group. Clinical features were compared between the two groups. Results Of the 24 young female AMI patients, MI from non-atherosclerosis was identiifed in 9 patients (non-ATS group). Compared to the remaining 15 young female AMI patients (ATS-group), non-ATS group was younger (P<0.05), with lower BMI (P<0.05) and less traditional risk factors of coronary heart disease (P<0.05). Coronary angiography showed more normal artery (P<0.05) and lesions on left main (P<0.05). However, when compared to the elderly group, the young female ATS-group was associated with less hypertension (P<0.01), smoking (P<0.05), traditional risk factors (P<0.01) and lower level of blood pressure (P<0.05), fasting glucose (P<0.05), serum creatine (P<0.01), TC (P<0.05), and LDL-C (P<0.01) at admission. Coronary angiography showed single vessel disease was the most common lesion. Conclusions Acute myocardial infarction in young female might be caused by non-atherosclerosis. Those due to atherosclerosis differ in coronary risk factors and angiographic features from the elderly female AMI patients.

In plant genetic engineering, selectable marker is needed to distinguish transformant. As the commercialization of transgenic plants, people are more and more paying close attention to their safety, among which mainly refers to the safety of selectable marker. In order to increase the safety of transgenic plants, biologists began to search for biosafe selectable marker.Current research progress of taking key enzyme in metabolic pathways were overviewed,which include glycometabolism, amino acid metabolism, hormone metabolism ,nucleotide metabolism and protein metabolism et cetera, as selectable marker in transgenic plants.

Obejective To explore the correlation of Orexin A and respiratory drive in chronic obstructive pulmo-nary disease (COPD) patients. Methods Pulmonary function was tested in 30 stable COPD patients and 20 normal healthy adults. Plasma orexin A level was measured with a radioimmunoassay kit. The correlation of Orexin A with BMI, age, BDI, FEV1, FVC, FEV1/FVC, MEP, MIP, P0.1 in COPD patients was analyzed. Results Plasma Orexin A levels in patients with COPD group(1.87±0.43)ng/L was higher than those in the control group(1.49±0.19)ng/L, P<0.01. Plasma Orexin A lev-els in patients with COPD correlated negatively with FEV1(r=-0.389,P < 0.05),and correlated positively with P0.1(r=0.728,P<0.01). Conclusion Plasma orexin A in COPD patients increased which may be caused by smoking and hyper-capnia. Orexin A may play a crucial role in regulating respiratory drive in COPD patients.

Objective To evaluate the function of p27 gene on the neointimal formation after balloon injury in rabbit carotid artery. Methods The cultured vascular smooth muscle cells (VSMCs) were infected with Adp27. Using MTT assay we measured the proliferation of VSMCs. Balloon injured rabbit carotid arteries were also infected with Adp27, and then we evaluated the ratio of intima to media. Results MTT assay of rabbit VSMCs proliferation demonstrated an obvious inhibition in Adp27 treated group. And p27 overexpression had an effect on the cell cycle. It could induce cell cycle arrest in G1 phase and reduce the cells in S phase. Overexpression of p27 could also reduce the neointimal hyperplasia by 27.43%. Conclusion The p27 gene can reduce the neointimal formation after balloon injury in rabbit carotid artery effectively.
