The body is at a hypo-coagulation status after the heart mechanic valve prosthesis replacement operation, and the incidence of anticoagulation complications is rather high because of that administration of warfarin may result in “anticoagulation vacuum” at an early stage. Moreover, the necessary application of other anticoagulation methods assisting the employment of warfarin have still not been scientifically normalized. Blood coagulation factor Ⅱ,Ⅶ, prothrombin fragment1+2 (F1+2 ), urine fibrimopeptide A (UFPA) , and International Normalized Ratio(INR), could exactly reflect the anticoagulation intensity 48-72 hours after the replacement operation,reasonable use of anticoagulant therapy as well as accurate and in-time monitoring methods is significant to reduce complications,elevate survival rate, and improve quality of life.
Abstract： Objective To analyze clinical outcomes of interventional therapy for common congenital heart diseases （CHD）. Methods We retrospectively analyzed the clinical records of 57 patients with CHD who underwent catheter interventional therapy in People’s Hospital of Deyang City between March 2009 and January 2012. There were 31 male patients and 26 female patients with their mean age of 29.4±3.5 years（ranging from 1.5 to 75.0 years）. There were 21 patients with patent ductus arteriosus （PDA）, 12 patients with ventricular septal defect （VSD）, and 20 patients with atrial septal defect（ASD）；and 2 patients with VSD plus ASD, 1 patient with VSD plus PDA, and 1 patient with ASD plus PDA. Occluder and supplying system made in China were used in the interventional therapy. For the patients with ASD plus PDA, PDA was blocked before ASD；for the patients with VSD plus PDA, PDA was blocked before VSD；and for the patients with VSD plus ASD, VSD was blocked before ASD. Results The duration of interventional therapy ranged from 30 to 90 minutes. The success rate of operation was 98.3%（56/57）. Operation was given up in an old female patient with ASD and chronic obstructive pulmonary disease because of pulmonary hypertension. The hospital stay was 3 -7 days. All the patients were followed up at the outpatient department for 1 month to 2 years by color Doppler echocardiogram, chest X-ray and electrocardiograph, and no complication occurred during follow-up. Conclusion With complete understanding of surgical indications and strict compliance with procedures, catheter interventional therapy is safe, minimal invasive, and effective in CHD treatment.
Objective To explore the effect of interfering RNA (shRNA) on biological activity of A549 cells and tumor growth in nude mice after knockdown of estrogen receptor α (ERα) gene. Methods The ERα gene in A549 cells was knocked down by shRNA. RT-PCR and Western blot were used to detect the gene expression and protein expression after knockdown; colony formation experiment was used to detect the proliferation of cells, and RT-PCR was used to detect the expression of Ki-67 and PCNA; flow cytometry was used to detect apoptosis rate; transwell assay was used to detect cell invasion ability; Western blot was used to detect the expression of epithelial cadherin (E-cad) and neuropathic cadherin (N-cad) protein. The control group and A549 cells transfected with ERα-shRNA1 were injected subcutaneously in nude mice to construct transplanted tumors. Immunohistochemistry was used to detect the expression of Ki-67 and N-cad in tumor tissues. Results Compared with the control group, after transfection of ERα-shRNA1 and ERα-shRNA2, the mRNA and protein expressions of ERα were reduced significantly (P<0.05), and shRNA1 with high interference efficiency was used for subsequent experiments. Compared with the control group, the A549 cells were transfected with ERα-shRNA1, the colony formation rate was down-regulated significantly (P<0.05), the apoptosis rate was increased significantly (P<0.05), the expression of Ki-67 and PCNA were down-regulated significantly (P<0.05), the number of invasive cells was reduced significantly, the expression of E-cad was increased, and the expression of N-cad was decreased (P<0.05). The results of tumor formation in nude mice showed that interfering with ERα expression can significantly inhibit tumor growth (P<0.05), and down-regulate the rate of Ki-67 and N-cad positive cells (P<0.05). Conclusion Knockdown of ERα inhibits the proliferation and migration ability of NSCLC cells and the occurrence and development of transplanted tumors in nude mice.
Objective To summarize the treatment and outcomes of patients with multiple injuries combined with thoracic trauma following the Wenchuan earthquake. Methods The wounded patients admitted from 12th to 31st May with multiple injuries combined with thoracic trauma after the earthquake were retrospectively analyzed. This includes baseline information, treatments, outcomes and deaths. Results Liver repair, spleen abscission, decompression and removed of intracranial hematoma ranked the first three of the main reasons for the emergency surgery death of multiple injuries. Heart-lung machine support, trachea cannula and closed drainage of thoracic cavity ranked the first three of the main reasons for the death of thoracic trauma. Moreover, ARDS, fracture of sternum and flail chest ranked the first three of the main reasons for the death of other multiple injuries. All the casualties had the worst situation with high ISS scores. The main death reasons were cerebral wound, peritoneum viscera injuries and the four limbs and pelvis injuries. Besides, the severe thoracic trauma accelerated their death. Conclusion Main death reasons for the inpatients with multiple injuries combined with thoracic trauma are hemorrhagic shock and severe cerebral wound. The thoracic trauma degree will increase the risk of their death. The more the injury positions, the higher ISS scores, and the more serious thoracic trauma, the higher mortality rate. Rapid examination and diagnosis, rapied triage and distribution of thoracic trauma can help to create more chances for the further treatment and increase the success rate of rescue.
