Objective To evaluate the value of echocardiography in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Methods The eehoeardiographie results of five patients with isolated anomalous origin of right pulmonary artery from ascending aorta were reviewed retrospectively. Results Severe pulmonary hypertension occurred in all the patients,besides accompanied with patent duetus arterious, no other congenital malformations combined. Three patients underwent operation. Patent ductus arterious was missed in one patient's diagnosis. Another patient was missed isolated anomalous origin of right pulmonary artery from ascending aorta in several echoeardiographic examinations, once misdiagnosed as complete transposition of the great arteries. Conclusions There are many anatomic and hemodynamic similarities in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Grasping their common charaeters and exploring multi-position and multi-section are helpful to make correct diagnosis.

Objective To evaluate the clinical value of transesophageal echocardiography (TEE) on minimally invasive surgical closure of heart septal defects. Methods Thirty-four patients with atrial septal defect (ASD) and 38 patients with ventricular septal defect(VSD) were selected by transthoracic echocardiography (TTE) prepared for minimally invasive surgical closure. TEE was performed to choose appropriate occluder and guide occluder release during the procedure. The immediate closure effect also evaluated by using TEE. A week follow-up was done by using TTE. Results Successful occlusion was in 32 patients with ASD and 29 patients with VSD. On 1 week follow-up,neither displacement for the occluders nor residual shunt except minimal residual shunt in 3 patients. The ventrieular remodeling was improved, the valvular regurgitation and pulmonary arterial pressure decreased. Conclusions TEE is important in minimally invasive surgical closure of atrial, ventricular septal defects, especially in choosing the candidate for the procedure and occluder, guiding occluder released and evaluating the procedure.

Objective To investigate the effects of Xuebijing injectio (Chinese herb preparation) on intestinal function and inflammatory responses in severe burn patients. Method Thirty-two patients with comparable severity in burn injury were randomly divided into Xuebijing injectio treatment group (n = 16) and control group (n = 16). Patients in both groups received routine burn therapy, while those in Xuebijing treatment group additionally received Xuebijing injectio 100mL in intravenous drip twice a day for 7 days. Before the treatment and on the 3rd and the 7th day after the treatment, blood concentrations of diamine oxidase (DAO), lipopolysaccharide (LPS) ,tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) were determined in both groups. Analysis was made by SPSS 12.0 software. Results The plasma levels of DAO, LPS, TNF-α and IL-6 were decreased in both groups after the treatment. However, the plasma levels of DAO, LPS, TNF-α and IL-6 in the Xuebijing treatment group were significantly lower than those in control group on the 3rd and 7th day after the treatment (P＜ 0.05).Conclusions Xuebijing injectio could protect intestinal function, decrease the plasma level of endotoxin and lessen zhe inflammatory responses in severe burn patients.

【Objective】To explore the therapeutic effect of TCM syndrome differentiation and treatment for immunoglobulin A(IgA) nephropathy.【Methods】The selected 123 patients with IgA nephropathy were divided into two groups(in the proportion of 3∶1) by number randomization.Group A(n=86) was given Tripterygium Glycosides tablets and differential treatment according to syndrome patterns,and Group B(n=37) was given routine western medicine including anti-inflammation drugs,drugs for controlling blood pressure and glucocorticoid hormone.The two groups received a 3-month treatment course and received one more course according to individual cases.The total therapeutic effect,effect for TCM syndrome patterns,and toxic and side effects were observed.The changes of TCM syndrome scoring were compared before and after treatment.【Results】In group A,symptoms were completely relieved in 29,markedly relieved in 30,relieved in 15 and un-relieved in 12 patients,the total effective rate being 86.05%,while respectively in 4,5,10 and 18 of patients in group B,the total effective rate being 51.35%.The total effect was better in group A than that in group B(P0.05).The improvement on TCM syndrome scoring in group A was superior to that in group B(P

OBJECTIVE To discuss the available methods of preventing the mattress pollution in the wards of the(hospital), and to keep the mattresses clean and dry and eliminate the hidden danger of nosocomial infection.(METHODS) The mattress protective covering is used of a new type of textile materials,and then applied into clinic.Selected 100 pieces of mattresses in the wards,divided them equally into two groups at random,the(experimental) group and the control group.After cleaning and pasteurization(surface) sampling and bacterial culturing for every mattress were undertaken.For the experimental group,spread the protective(covering) before the sheet,and for the control group,used the sheet directly.The colony number of each group was compared in the 3rd,7th,and 14th days.RESULTS The mattresses of experimental group were clean,light polluted and with less colonies,and that of the control group were heavy polluted and with more colonies.The comparisons of the total colony number and the number of every sampling point in the 3rd,7th,and 14th days of the two groups showed that there was a(significant) difference(P

ObjectiveTo investigate the platelet inhibition ratio by thromboelastography (TEG) and its clinical impact in patients undergoing percutaneous coronary intervention (PCI). Methods118 PCI patients were divided into ischemic events group (22 cases) and nonischemic events group (96 cases) according to their clinical follow-up of 6 months. Platelet inhibition ratio was measured by TEG. ResultsADP-induced platelet inhibition ratio of ischemic events group decreased significantly compared with nonischemic events group (P<0.01). And there were no significant differences in AA-induced platelet inhibition ratio between two groups (P＞0.05). ConclusionThere may be some relationship between the ischemic events of PCI patients and their drug resistance to clopidogrel.

Aim To investigate the up-regulation of miR-22 through Wnt pathway inhibits the proliferation,migration and invasion in human gastric MGC803 cells induced by diallyl disulfide(DADS).Methods The effects of proliferation,migration,and invasion of gastric cancer cells were evaluated by MTT,wound-healing and invasion assays.Online prediction software was applied to search the target gene of miR-22.Luciferase report gene assay was used to assess the target genes Wnt-1 of miR-22.The expressions of Wnt-1,β-catenin and TCF-4 were tested by qRT-PCR and Western blot,respectively.Results MTT showed that DADS and miR-22 notably decreased the proliferation compared with control group(P<0.05).Wound-healing assay showed that DADS and miR-22 could significantly inhibit the migration of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Invasion assay showed that DADS and miR-22 could markedly inhibit the invasion of MGC803 cells compared with the control group, especially in miR-22+DADS(P<0.05). Online prediction software to search the target gene exhibited that Wnt-1 may be a target gene of miR-22. Luciferase report gene assay disclosed that Wnt-1 was identified as a direct target of miR-22. Qrt-PCR showed that the expression of Wnt-1 Mrna was respectively down-regulated by DADS and miR-22 compared withcontrol group, especially in miR-22+DADS(P<0.05). Western blot exhibited that DADS and miR-22 obviously suppressed the expressions of Wnt-1, β-catenin and TCF-4 proteins, especially in miR-22+DADS(P<0.05).Conclusion Up-regulation of miR-22 through Wnt pathway can remarkably suppress the proliferation, migration and invasion in MGC803 cells by DADS.

Objiective To evaluate the effect of pearventricular device closure of non-muscular ventricular defercts(VSDs) in infants.Methods From April 2007 to February 2008,39 patients with non-muscular VSDs were received off pump surgical treatment,perventricular device closure were for all the patients.There were 16 males and 23 females with mean age of(14.5±7.8) months(12 to 36 months and mean weight of(12.4±2.3)kg(8.5 to 18.0 kg).There were 34 perimembranous and 5 subateria VSD.The diameter of defects were 3.0 to 11 mm[mean(6.1±2.0)mm].Results Thirty-seven(94.9%)VSDs ere successfully closed,while two were repaired under cardiopulmonary bypass(CPB)instead of device closure because of the complication of moderat aortic reurgitation.The diameter of occluders were 4 to 12mm[mean(8.2±2.0)mm].The tricuspid regurgitations decareasded after operation in 3 patients with perimenmbranous VSDs,while the closure caused new mild or trace tricuspid regurgitations in 8 patients.Six patients with perimembranours VSDs acquired the incomplete right bundle branch blocks affter device closure.The length of hospital stay was 3 to 5 days[mean(3.4±0.4)]after operation and no petient had blood transfusion.Conclustion Perventricular device closure is probably an effective and safe treatment for non-muscular VSDs in unfants.

Objective To evaluate the efficacy of intraopèrative ultrasonography (IOUS) on primary and repeated hepatectomies for hepatocellular carcinoma (HCC).Methods 430 patients underwent 555 operations for HCC.New tumors detected by IOUS at the primary and repeated hepatectomies were retrospectively analyzed.The long-term outcomes were also studied.Results IOUS had the highest sensitivity in the routinely used imaging examinations.The detection rate by each imaging modality decreased slightly but uniformly at the second hepatectomy.IOUS detected 56 new tumors in 30 patients (7.1％) at the primary hepatectomy and 13 new tumors in 8 (7.3％) at the second.The average size of tumor detected was 8.7±3.8 and 9.0±5.2 mm at the primary and second resections,respectively.The preoperative surgical plan was changed due to the IOUS findings alone in 24 patients (5.6％) at the primary hepatectomy,and in 7 (6.4％) at the second.Although recurrence was frequent in patients with new tumors detected at the primary hepatectomy,long-term survival after appropriate treatment for recurrence was similar to those patients without new tumors detected.Conlusions Despite recent progress in imaging modalities,IOUS is still the most sensitive examination.The same degree of precaution is necessary to detect new tumors using IOUS in repeated hepatectomy.Patients with new tumors detected by IOUS are at high risk for recurrence so that regular check-up is important to improve patient survival.
