ABSTRACT
The case was a 70-year-old female. Atrioventricular septal defect was diagnosed in her childhood, however, surgical treatment had not been performed. The patient had suffered from heart failure at the age of 69, and she was referred to our hospital for treatment. Her diagnosis was intermediate type atrioventricular septal defect, moderate left atrioventricular valve regurgitation, membranous ventricular septal aneurysm and atrial flutter. An autologous pericardial patch was used to close the ostium primum type atrial septal defect associated with simultaneous covering of membranous ventricular septal aneurysmal wall. Concomitant left and right atrioventricular valvuloplasty and arrhythmia surgery were performed. Her postoperative course was uneventful and the patient was discharged from our department on the 16th postoperative day. To our knowledge, there are few reports of surgery for incomplete type atrioventricular septal defect in the elderly and no report for intermediate type atrioventricular septal defect in Japan. In incomplete type atrioventricular septal defect, symptoms such as supraventricular arrhythmia and heart failure develop according to aging. Reported surgical results in the elderly are quite good, and improvement of excise tolerance is expected. Precise evaluation and proper indication of surgical treatment is mandatory even in older patients.
ABSTRACT
Objective To analyze the genotype distribution characteristics in the patients with α-thalassemia and the relationship between hematological phenotype and genotype .Methods 209 cases of α-thalassemia in our hospital from August to October 2016 were selected and divided into the silence type group (58 cases) ,standard type group(138 cases) ,intermediate type group(4 cases) and non-deletion type group(9 cases) .Contemporaneous 25 subjects undergoing healthy physical examination were selected as the normal control group .The automatic capillary electrophoreses was adopted to detect HbA 2 .The hematological indicators of MCV , MCH and MCHC were detected by using the automatic blood cells analyzer .Results Among 209 cases ofα-thalassemia ,8 mutation genotypes were detected ,in which - - SEA/αα deletion type accounted for 66 .03% ,- α3 .7/αα deletion type accounted for 22 .97% .The levels of MCV ,MCH and MCHC in the silence type group ,intermediate type group ,standard type group and non-de-letion type group was significantly lower than that in the normal control group ,the difference was statistically significant ( P<0 .05) ,the HBA2 level in the intermediate type group was lower than that in the normal control group ,the difference was statisti-cally significant (P<0 .05) ,but the HbA2 level had no statisticval difference between the silence type group ,standard type group and non-deletion type group with the normal control group(P>0 .05) .Conclusion The gene mutation in the patients with α-thalas-semia in Luohu District of Shenzhenis City is dominated by the deletion type of - -SEA/αα.The hematological indicators such as MCV ,MCH and MCHC can serve as the combined screening indexes of α-thalassemia ,but for the patients with -α3 .7/ααgenotypeα-thalassemia ,there is the possibility of missed diagnosis .
ABSTRACT
Asteraceae family shows a great diversity in Cuba and presents threatened taxons in high number. Pinar del Río has 19 threatened species belonging to this family and three of them are characteristic of a sandy (quartzitic) soil at the Reserva Florística Manejada San Ubaldo-Sabanalamar (Floristic Reserve San Ubaldo-Sabanalamar). The arbuscular mycorrhizal status and colonization rate in Aster grisebachii, Erigeron bellidiastroides, Erigeron cuneifolius, Pectis juniperina and Sachsia polycephala (Asteraceae) from this Reserve was determined in October 2009 and April 2010, during hydrologic rainy and dry period, respectively. All species were mycotrophic in both periods with a high percentage of colonization rates, between 66 and 100% in rainy period and between 84 and 100% in dry period. Vesicles, arbuscules, spores, hyphal and arbuscular coils of arbuscular mycorrhizae were observed. Paris -type and Arum -type morphologies (both) were observed indistinctly in all the species, and Intermediate type was observed only in Aster grisebachii and Erigeron bellidiastroides, which could be a hint that these species are colonized by more than one fungal species, and therefore enhancing the relevance of fungal identity as a considerable character in the morphology association. Also, septate hyphae and microsclerotium of dark septate endophytes were identifyed inside the roots of all the species.
La familia Asteraceae muestra una gran diversidad en Cuba y presenta un elevado número de taxones amenazados. Pinar del Río cuenta con 19 especies amenazadas pertenecientes a esta familia, de las cuales tres son características de los suelos arenosos cuarcíticos de la Reserva Florística Manejada San Ubaldo-Sabanalamar. Se determinó el estatus micorrízico arbuscular y la tasa de colonización de Aster grisebachii, Erigeron bellidiastroides, Erigeron cuneifolius, Pectis juniperina y Sachsia polycephala (Asteraceae) presentes en esta Reserva, en octubre del 2009 y abril del 2010, durante los períodos hidrológicos húmedo y seco, respectivamente. Todas las especies estaban micorrizadas en ambos períodos con elevados porcentaje de colonización micorrízica, entre 66 y 100% en el período lluvioso y entre 84 y 100% en el período seco. Se identificaron vesículas, arbúsculos, esporas, enrollados hifales y arbusculares característicos de las micorrizas arbusculares. Los tipos morfológicos Paris y Arum (ambos) fueron observados indistintamente en todas las especies, y el tipo Intermedio solo se observó en Aster grisebachii y Erigeron bellidiastroides, lo cual sugiere la colonización de estas especies por más de una especie fúngica y con ello la importancia de la identidad fúngica en la determinación de la morfología de la asociación. Se identificaron además, hifas septadas y microesclerosios de endófitos oscuros septados en el interior de las raíces de todas las especies estudiadas.
