ABSTRACT
Objective To investigate the effects of abdominal breathing training on sleep disorders in elderly patients with chronic heart failure. Methods Total of 100 patients with chronic heart failure complain of sleeping disorders and Pittsburgh Sleep Quality Index (PSQI)>7 points were assigned into two groups by random digits table method, 50 cases in each group. The observation group and the control group were nursed in the same way except that abdominal breathing was adapted to the observation group. Sleep status, heart rate, blood pressure, SpO2 and brain natriuretic peptide (BNP) were evaluated before training, one week and eight weeks after training respectively. Statistics was used to analyze the differences between two groups. Results After training one week, the sleep status of the observation group was ameliorated, but without significant difference compared to the control group (P>0.05). And after training eight weeks, the PSQI, BNP and heart rate were (9.21 ± 6.38) points, (193.78 ± 152.16) μg/L, (63.5 ± 10.8) times/min in the observation group, and (12.92 ± 0.33) points, (417.55 ± 262.47) μg/L, (70.7 ± 8.5) times/min in the control group, and there was significant differences between 2 groups (t=3.627, 2.041, 2.767, all P 0.05). Conclusions Abdominal breathing training could ameliorate sleep status in elderly patients with chronic heart failure.
ABSTRACT
Cystic echinococcosis is one of the most widespread and severe zoonotic helminthic diseases .To understand the phylogeny and genetic polymorphism Echinococcus granulosus (E .granulosus) prevailed in south region of Qinghai Prov-ince ,partial fragment of cytochrome oxidase Ⅰ (COX Ⅰ ) gene sequences were used to infer the phylogenetic relationship of 59 collected samples of E .granulosus in Qinghai Province .Total 72 sequences (13 sequences from GenBank) were aligned using CLUSTAL X ,and then ,Bayesian analyses were performed in Mrbayes-3 .1 .2 .The results revealed that Echinococcus spp .isolates did not form a monophyletic group .The most samples clustered with E . granulosus strain (G1) (AB297617) , but showed high genetic polymorphism .Another three samples clustered with E .multilocularis (AB018440) ,while they showed complex phylogenetic relationships among them ,further indicating that Echinococcus spp .isolates from Qinghai Prov-ince may has a more complex evolutionary history than expected .
ABSTRACT
One of the focuses in bone and cartilage tissue engineering research is to find suitable seed cells. Embryonic stem cells derived from the inner cell mass of blastocysts possess unique characteristics such as unlimit- ed capacity of proliferation and the potential to differentiate into diverse cell types (pluripotentiality), which make them a promising cell source for tissue engineering. In this paper, the progress in the study on embryonic stem cell differentiating directly into osteoblasts and chondrocytes is introduced. The prospects and difficulties of using em- bryonic stem cells as seed cells for tissue engineering are also discussed.
ABSTRACT
The teaching model of Problem-Based Learning(PBL)is quite effective in developing the students’learning capacity, analytical and problem resolution skill and their ability to think independently and logically. The article summed up the instructional design, implementation of training and teaching effectiveness of PBL teaching model in medical microbiology.
