Objective:To investigate the role of thoracic echocardiography in diagnosis and differential diagnosis of the right ventricular outflow tract into the right aorta with right ventricular aneurysm rupture.Methods:A total of 19 patients with sinus rupture caused by ventricular septal defect in the right ventricular outflow road were reviewed.These patients were diagnosed as aortic right coronary sinus by preoperative transthoracic echocardiography from February 2010 to September 2016 in Xiangya Second Hospital and Xiangya Medical College Affiliated Haikou Hospital.The clinical symptoms,echocardiography and intraoperative lesions were compared and analyzed among the patients.Results:The intraoperative lesions were consistent with the preoperative echocardiographic diagnosis in 16 patients.Among them,11 cases could be heard the continuous sound of the machine with systolic murmur and no tremor in left sternal rib 2-3 auscultation.The color Doppler imaging of right ventricular systolic indicated the based continuous Doppler spectrum.The preoperative echocardiography and intraoperative lesions testified the ventricular septal defect size and the right ventricular outflow tract into the right aorta with right ventricular aneurysm rupture.Among them,3 cases were complicated with other heart diseases.Other 3 cases were not accorded with the preoperative diagnosis.There were auscultation smell and noise but no tremor.The preoperative echocardiography and lesions indicated the right ruptured aneurysm of the sinus of big and long mouth,1 case with aortic valve stenosis and regurgitation,congenital aortic valve two valve malformation,1 case with aortic valve-severe reflux,1 case with pulmonary infection,and 3 cases with no intraoperative lesions in the ventricular septal defect.Conclusion:Preoperative transthoracic echocardiography is the preferred preoperative,quick and noninvasive method for ruptured aneurysm.Each stage of observation procedure and method can observe the ruptured aneurysm of aortic sinus,the location,size and adjacent ofventricular septal defect.Meanwhile,the flow spectrum characteristics of the ventricular septal defect in the right outflow tract of the right sinus aneurysm can be found by Doppler ultrasound imaging.

Objective To investigate the correlation between the olasma concentrations of angiotesin Ⅱ,aldosterone and the parameters that reflected the reconstruction of left ventricular in chronic heart failur(CHF)patients.Methods 61 CHF pmiems and 20 normal control subjects were enrolled.plasma concentration of angiotesin Ⅱ,aldosterone were measured by specific radioimmunoassays.Two dimensional,M-mode and Doppler ultrasound recording were obtalned to determine left vantricular mass index(LVMI),left ventricular ejection fraction(LVEF)and maximal early transmitral flow velocity in diastole(VE)and maximal late transmittal flow velocity(VA).Results Baseline plasma concemrations of angiotesin Ⅱ,aldostemne were increased significantly in CHF patients as compared with normal thme of control group and were paralleled to the increase of NYHA cardiac functional classification of CHF(P＜0.01).Plasma concentrations of angiotesin Ⅱ,aldostemne were positively correlated with LVMI but negatively correlated with VE/VA(P＜0.01).Conclusion Plasma concentrations of angiotesin Ⅱ,aldosterone were increased signifcantly in CHF patients and might be involved in and regulated the reconstruction of left ventricular in CHF patients.

3-Hydroxy-3-methylglutaryl-coenzyme A reductase (HMGR) is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate (MVA) pathway. The specific primers were designed according to the transcript sequence of AsHMGR2 from the Aquilaria sinensis (Lour.) Gilg transcriptome database. The full-length cDNA of AsHMGR2 was cloned by RT-PCR and rapid amplification of cDNA ends (RACE) technology, and was analyzed at bioinformatics levels; AsHMGR2 expression profiles in different tissues and in responds to different treatments were analyzed by real-time PCR. The length of AsHMGR2 Open Reading Frame (ORF) was 1 749 bp, encoding 582 amino acids. The GenBank accession number is KC140287. Tissue expression analysis indicated that AsHMGR2 was mainly expressed in root and shoot tips, followed by stem, and was lowest in leaves. Inducible-experiments showed that the genes were induced by mechanical wound as well as chemical liquid induction, and reached the highest expression level at 6 h and 8 h, separately. The full-length cDNA of AsHMGR2 and its expression patterns will provide a foundation for further research on its function in agarwood sesquiterpene biosynthesis.

Objective:To study the inhibition of astragaloside on the proliferation of human keloid fibroblasts. Methods: Com-pared with that of normal skin, the expression of transforming growth factor-β( TGF-β) and its transduction factors Smad in the human keloid fibroblasts was detected. The optimal concentration was screened by MTT after HFF-1 human skin fibroblast was infected with astragaloside at different concentrations. The mRNA expression of Smad2, Smad3, Smad4 and Smad7 in the fibroblasts was studied by using real-time. The protein expression of TGF-βRⅡ, Smad2, Smad3, Smad4 and Smad7 in the fibroblasts was detected by using Western blot. Results: Compared with that of normal skin tissue, the expression of Smad protein was significantly increased ( P <0. 05) in the human keloid fibroblasts, and there was no significant difference in the TGF-βRⅡ expression (P>0. 05). The optimal concentration of astragaloside was 0. 5μg·ml-1 . The expression level of Smad2 protein in the two groups was significantly increased, and the level of Smad3 expression was significantly decreased (P<0. 05). Conclusion:Astragaloside can inhibit the formation of fi-broblast possibly through Smad2 over-expression and Smad3 inhibition in the TGF-β/Smad signal transduction pathway.

Objective To study the effects of ginkgo biloba extract(GBE)on c-reactive protein(CRP) and tumor necrosis factor-α(TNF-α)in serum and alveolar lavage fluid(BALF)from rats with chronic obstructive pulmonary disease(COPD). Methods 90 rats were randomly divided into groups A,B,C,D,E and F. There were 15 rats in each group. The rat model of COPD were established in groups B,C,D,E and F. Groups C and D were given intraperitoneal injections with GBE from day l to day l4 and day 29 to day 42. Groups E and F weregiven intraperitoneal injections with erythromycin from day l to day l4 and day 29 to day 42. After the end of experi-ment ,the contents of CRP and TNF-α in serum and BALF were detected in all groups. Results The contents of CRP and TNF-α in the serum and the BALF were markedly lower in groups C,D,E and F than in group B (P<0.05);and the contents of CRP in the serum and the BALF and TNF-αin the BALF were lower in groups C, E and F than in group D(P<0.05). Conclusions GBE can inhibit the airway and systemic inflammatory response in COPD rats. Early intervention is more effective.

AIM: To study the exciting effects of ethanol extract of capitate phrynium (Phrynium Capitatum Willd) stem and leaf on the uterine smooth muscle of rat,mice,guinea pig and rabbit pretreated by diethylstilbestrol. METHODS: Conventional method was adopted to prepare animal uterine specimens both in vivo and in vitro. Different doses of the extract were given to the specimens and recorded their tensility, frequency and activity of contraction with the help of BL-420 biological experimental system. IC_(50) of the extract was calculated, with oxytocin as standard comparison. RESULTS: 95% ethanol extract and 50% ethanol extract of capitate phrynium and leaf had obviously stimulating action on the uterine smooth muscle of rat, mice, guinea pig and rabbit in a dose-dependent manner in vitro, whichinclude accelerating contraction frequency, raising tension (P<0.05, P<0.01). In addition, 50% ethanol extract also had a significant stimulating action on uterine smooth muscle of rabbit in vivo(P< 0.01). CONCLUSION: Ethanol extracts of capitate phrynium have an effect on rodent uterine. Smooth muscle indicates that clinical application of Chinese practitioner used to treat the dysfunctional uterine bleeding proves to be effective.

Objective To compare the difficult degree,differences in gastric pouch volume,the complications,and postoperative weight loss effect of two gastric pouch practices in laparoscopic gastric bypass for bariatrics.Methods We retrospectively analyzed laparoscopic gastric bypass surgery in 76 bariatrics cases from May 2010 to May 2012.Two methods were used to create gastric pouch,among which 39 cases were operated with the dissection landmark method (called dissection),and 37 cases with bougie airbags 30 ml (called the bougie).Parameters were compared between the 2 groups including operation time for gastric pouch,the amount of staple cartridges,intraoperative complications,blood loss,and postoperative excess weight loss percentage (EWL ％),the postoperative bleeding,obstruction,fistula and other complications.Results All patients were followed up for more than one month.The dissection group used longer time in creating gastric pouch than that in the bougie group [(58 ± 27) min,(42 ±21) min,P ＜ 0.01].The number of staple cartridges used were significantly different between the two groups [(6.2 ±3.0),(4.3 ± 2.0),P ＜ 0.01].There were 10 cases of complications in the dissection group (26％),and 3 cases in the bougie group (8％) (P ＜0.05).One month after the surgery,one each patient had transient hematochezia.There was no gastric pouch-related complications in the two groups postoperation.There was no difference in excess weight loss (P ＞ 0.05).Conclusions The two methods can achieve the same effect on excess weight loss.The bougie method used less time in creating the gastric pouch,less consumable materials,and less complications occurred in creating gastric pouch.

Objective To analyze the CT findings of heterotopic pancreas and the correlation with pathologic changes.Methods CT findings in 1 9 patients with heterotopic pancreas proven by surgery were reviewed retrospectively,14 of whom were scanned with enhanced CT.The correlation of CT findings and pathologic results were also analyzed.Results All patients had a single lesion with sized range from 0.8 to 4.7 cm and mean diameter of (2.2±0.6)cm.All lesions with homogeneous density were showed on plain scans including 7 lesions in stomach,8 in duodenum,2 in jejunum,1 in ileum and 1 beside the cardiac lymph nodes.The border of the lesions in 5 was unclear with exudative changes,mimicking acute pancreatitis.A sign of central umbilical concave was found in 2.Pathological results confirmed 14 lesions in submucosa,3 in muscular layer,1 in serosal layer and 1 in abdominal cavity.Hetero-topic pancreas presented early obvious enhancement in 9,mimicking normal pancreas,which was composed chiefly of pancreatic aci-ni.The enhanced degree of 4 lesions was lower than normal pancreas,which were composed of pancreas ductal epithelium and few pancreatic acini.No significantly enhancement was seen in 1,mimicing liomyoma,which was composed chiefly of pancreas ductal epithelium and smooth muscle hyperplasia.Conclusion Heterotopic pancreas in most cases presents characteristic submucosal disea-ses-like pattern,and different enhanced patterns of heterotopic pancreas are related with the pathologic changes.
