Objective To investigate the refraction change and nursing character in myopic amblyopia during the perceptual learning treatment. Methods Refraction of 54 children (98 eyes) with myopic amblyopes were selected,which were selected from the amblyopia clinic between 2007 and 2009, the spherical diopter, astigmatism and spherical equivalent were collected before and after perceptual learning,the refractive dynamic was compared according to the degree of amblyopia. Results The spherical average annual growth of myopic amblyopia during treatment was 0.52D, the growth of astigmatism was 0.03D;the spherical equivalent average annual growth was less than 0.50D accounted for 57.14%. The dynamic changes of spherical or SE of mild, moderate and severe amblyopia had significant difference, but the cylinder had not significant difference in change. Conclusions The treatment of perceptual learning in patients has little effect on the growth of refraction in myopic amblyopia, however, it is still necessary to pay close attention to refraction changes of in myopic amblyopia in the course of treatment.

Object To observe the protective effect of Shexiang Antithrombosis Pill (SATP) on experimental cerebral ischemia in rats. Methods In cerebral ischemia model induced by bilateral common carotid artery clamping and controlled hemorrhage to a mean arterial pressure of 6.7 kPa (50 mmHg), cerebral water content, SOD activity, MDA, Ca 2+ , and LA contents were measured and the ischemic tissue pathology was observed. Results SATP can decrease cerebral water content, lessen pathological change, increase SOD activity and decrease MDA, Ca 2+ , and LA contents. Effect of water pill is better than that of honey pill. Conclusion SATP can protect the cerebral tissue from ischemia injury by suppressing lipid peroxidation. This effect may be related to increasing antioxidase activity and decreasing acidosis of LA and overload of calcium in cell.

The manifestations of current poor doctor -patient communication are: doctors have insufficient communication beforehand , randomness is big , communication is not detailed or in -depth , the patients also have certain shortcomings .The causes of this situation are: interests driven factors , lack of education supervision and management , service responsibility consciousness weakening .Therefore , should strengthen the propaganda and ed-ucation, raise awareness, constantly enhance the consciousness of doctor -patient communication; to strengthen the construction of medical ethics , to reconstruct the doctor -patient integrity , play up the solid foundation of doc-tor-patient communication;Strengthen supervision and management , establish and improve the system , to insure the good doctor-patient communication , orderly and transparent;reinforcement learning training , pay attention to the accumulation of human skills to develop and enhance the effectiveness of doctor -patient communication .

Objective To analyse the high-dose dexamethasone suppression test(HDDST)-related differences in the clinical and biochemical features of the patients with Cushing's disease Methods Cases were drawn from 60 consecutive patients with Cushing's disease,who were then divided into two groups according to the response to the HDDST.The clinical and biochemical features between two groups were compared.Results(1) Of the 60 patients with Cushing's disease,23.3%(14/60)of patients(group A)did not yield results of suppression with the HDDST,and the others(group B)did.No difference was found in the age[(33.8?10.4 vs 36.2?11.2)years]and duration of illness[(2.1?1.6 vs 3.9?3.1)years]between two groups.(2)In clinical features,the patients in group A were more likely to have edema of lower limbs(64.3% vs 32.6%),hypokalemia (71.4% vs 28.3%),secondary diabetes(57.1% vs 26.1%)and purple striae(85.7% vs 54.3%,all P

Objective:To investigate the routine ultrasonographic findings of fibrinous breast disease lesions , and to provide the basis for the differential diagnosis of fibrocystic breast disease lesions and breast cancer.Methods:The two-dimensional ultrasonography , color doppler flow and elastography of 166 lesions in 144 patients with fibrocystic breast disease confirmed by pathology in Peking University Shenzhen Hospital from January 2015 to February 2021 were retrospectively analyzed.Results:The ultrasonographic characteristics of fibrocystic breast disease lesions were as follows: 74.1%(123/166) lesions were hypoechoic, 57.2%(95/166)lesions were irregular, 49.4%(82/166) lesions were incomplete, 90.4%(150/166) lesions were parallel, 25.9%(43/166) lesions showed small cysts, 24.1%(40/166) lesions showed coarse calcification or fine calcification, 65.1%(108/166) lesions showed no change in posterior echo, 90.4%(150/166) blood flow was poor. The elastography score of 98.2%(162/166) lesions was 2-3 points.Conclusions:The ultrasonographic features of fibrocystic breast tumor are hypoechoic, irregular shape, incomplete edge, with fine or coarse calcification, which are easy to be misdiagnosed as breast malignant tumor. However, the former is characterized by parallel growth, small cyst in the interior, no change in posterior echo, lack of blood supply and soft texture, which provide important basis for clinical differential diagnosis.

Objective To study the effect of lithium chloride on the gap junction in the myocardium under chronic hypoxia.Methods Twenty-five C57BL/6J mice were randomly divided into normoxia group,hypoxia group,normoxic control group,hypoxia + saline group and hypoxia + lithium chloride group.Hypoxia group was treated with 10％ oxygen concentration for 4 weeks.Hypoxia + saline group and hypoxia + lithium chloride group were intraperitoneal injection of saline and lithium chloride.Electrophysiology and cardiac catheterization were used to assess arrhythmias,heart rate and ejection fraction.The expression of Cx43,phosphorylated glycogen synthase kinase 3β(p-GSK-3β) and glycogen synthase kinase 3β (GSK-3β) were detected by Western blot.Results Compared with the normoxia group,the hypoxia group had a faster heart rate [(448 ± 18) bpm vs.(401 ± 13) bpm,P＜0.05),and the ejection fraction was decreased [(56±5)％ vs.73±4)％,P＜0.05],arrhythmia score increased [(3.4±0.5)％ vs.(0.6±0.5)％,P＜0.05],Cx43 expression was decreased.Compared to hypoxia + normal saline group,the heart rate decreased[(412±11)bpm vs.(454±18)bpm,P＜0.05],ejection fraction increased[(69±3)％ vs.(55±4)％,P＜0.05],the score of arrhythmia decreased [(1.8±0.4) ％ vs.(3.0±0.7)％,P＜0.05] in hypoxia + lithium chloride group,the expression of Cx43 and the rate of p-GSK-3β to GSK-3β were increased.Conclusion During the chronic hypoxia,lithium chloride can sustain the gap junction through inhibition of GSK-3β signaling way,which can also reduce the rate of arrhythmia.
