Medicine is a comprehensive discipline.Under the new situation,medical students are required to have integral knowledge and whole view.This article aims at evaluating the necessity of diagnosis and discusses the defects,causes and strategy in this respect.

Turner syndrome (TS) is the result of complete or partial deletion of an X chromosome. It is often associated with endocrine dysfunction such as thyroid dysfunction, growth and developmental disorders, glucose and lipid metabolism disor-ders, and so on. Long-term follow-up of children with TS should regularly monitor thyroid autoantibodies, thyroid function, blood glucose and blood lipids for early detection and intervention of the complications, in order to further improve the life quality of children with TS.

Objective To observe and analyze the four changes of plasma D- dimer and coagulation in pregnant women at different stages of pregnancy, and to explore the value of the test. Methods The subjects of this study were 120 pregnant women who underwent routine physical examination in our hospital, according to different stages of pregnancy (early pregnancy, middle pregnancy, late pregnancy, and before delivery) Four D- dimer and four blood coagulation tests were performed in pregnant women, and the results were observed and compared. Results During the pregnancy, D- dimer has increase trend (P<0.05); early in pregnancy, pregnancy and late pregnancy, PT has shortened(P<0.05); pregnancy, APTT has shortened (P<0.05), at the end of pregnancy and parturient period, showing a significant shortening (P<0.05); phenomenon in early pregnancy to mid pregnancy stage, FIB increased significantly (P<0.05), and at the end of pregnancy to perinatal period, with a sharp increase (P<0.05). Conclusion It is of great significance to perform dynamic monitoring of of plasma D- dimer and coagulation four indices in pregnant women during pregnancy.

ObjectiveTo investigate the risk factors for recurrent ischemic stroke in patients with atrial fibrillation.MethodsThe ischemic stroke patients with atrial fibrillation were enrolled retrospectively.Their demographic and clinical data were collected.The relative risk factors for strokes were compared in the first-ever stroke group and the recurrent stroke group.Multivariate logistic regression analysis was used to determine the independent risk factors for recurrent ischemic stroke in patients with atrial fibrillation.ResultsA total of 504 ischemic stroke patients with atrial fibrillation were enrolled, including 245 males (48.6%).and 259 females (51.4%).The average age was 76.67±8.26 years.There were 314 patients (62.3%) in the first-ever stroke group and 190 (37.7%) in the recurrent stroke group.The proportions of hypertension (78.9% vs.69.4%;χ2=5.446, P=0.020), diabetes mellitus (38.9% vs.26.8%;χ2=8.181, P=0.004), and age >75 years (68.9% vs.60.2%;χ2=3.915, P=0.048), as well as the baseline systolic blood pressure (153.30±26.02 mmHg vs.148.13±26.40 mmHg, 1 mmHg=0.133 kPa;t=-2.141, P=0.033) in the recurrent stroke were significantly higher than those in the first-ever stroke group.Multivariable logistic regression analysis showed that hypertension (odds ratio [OR] 1.734, 95% confidence interval [CI] 1.121-2.682;P=0.013), diabetes (OR 1.757, 95% CI 1.188-2.597;P=0.005), and age >75 years (OR 1.680, 95% CI 1.132-2.494;P=0.010) were the independent risk factors for recurrent ischemic stroke in patients with atrial fibrillation.ConclusionHypertension, diabetes, and age >75 years were the independent risk factors for recurrent ischemic stroke in patients with atrial fibrillation.

Bruton tyrosine kinase (Btk) is a member of the non-receptor protein tyrosine kinases of Tec family.It plays an important role in growth,proliferation,differentiation and signal transduction of B lymphocyte.After activation of B-cell receptor (BCR) by diverse stimuli,Btk is activated through tyrosine phosphorylation.Activated Btk can stimulate several downstream signaling proteins.Btk and BCR signaling pathways play important roles in initiation and maintenance of B cell malignancies.This review focuses on the recent findings in association of Btk and B cell malignancies.

Objective To investigate the diagnostic value of growth hormone(GH) stimulating test in dwarfism of children and related influencing factors .Methods Arginine and L‐dopa were applied to perform GH stimulating test in 642 children with dwarf‐ism .GH levels were detected at 30 ,60 ,90 ,120 ,150 ,180 min after stimulation .All children were divided into GH deficiency (GHD) group ,with peak value of GH less than 10 ng/mL ,and non‐GHD group ,with peak value of GH at least 10 ng/mL .Physical and la‐boratory data of the two groups were compared .Results The proportion of children with GHD and without GHD were 68 .69%and 31 .31% ,respectively ,and with statistical difference(χ2 =6 .19 ,P<0 .05) .The GH peak value ,with a delay ,mainly appeared at 30 and 150 min after stimulation ,accounting for 22 .42% and 34 .27% .Levels of age ,body height standard deviation ,body mass in‐dex ,alanine aminotransferase ,aspartate aminotransferase ,insulin growth factor‐1 and 25‐hydroxyl vitamin D were statistically dif‐ferent between the two groups(P<0 .05) .Conclusion Arginine and L‐dopa combined stimulating test could be used for the diagno‐sis of GHD in children with dwarfism .GH level might be correlated with various physical and laboratory parameters ,which should be considered for the diagnosis of GHD .
