ABSTRACT
Objective:To explore the application effect of the blended learning based on Rain Classroom in normal human morphology course.Methods:A total of 118 undergraduates majoring in medical laboratory technology of Batch 2017 and Batch 2018 from Xinjiang Medical University were included in this study, and they were divided into the observation group (Batch 2018) and the control group (Batch 2017), with 59 students in each group, adopting the traditional teaching method and blended learning method based on Rain Classroom respectively. The mid-term, final and comprehensive scores of the two groups were compared by t test and chi-square test through SPSS 23.0. And the evaluation of teaching satisfaction of the observation group was obtained by the questionnaire survey. Results:The mid-term results [(74.02±8.71) vs. (62.00±8.97), t=-6.073, P<0.001], the final results [(83.21±7.73) vs. (70.44±11.43), t=-6.250, P<0.001], and the comprehensive results [(82.26±9.53) vs. (70.52±11.09), t=-6.012, P<0.001] of the observation group were significantly superior than those of the control group ( P<0.05). The excellence rate of the final results (23.72% vs. 3.45%, χ2=10.412, P=0.001) and comprehensive results (18.64% vs. 5.08%, χ2=5.187, P=0.023) in the observation group were significantly higher than those in the control group ( P<0.05). The results of the questionnaire survey showed that the observation group generally had a good satisfaction with the blended learning. Conclusion:The blended learning could make up for the deficiency of the traditional teaching methods, have preferable teaching effects, and get wide recognition from students.
ABSTRACT
Objective To explore the relationship between genetic polymorphisms of sixtransmembrane protein of prostate 2 (STAMP2) and metabolic index,TNFα in Xinjiang Uygur population.Methods STAMP2 gene functional regions were sequenced in Uygur Xinjiang population diagnosed as metabolic syndrome.Patients were divided into the following three groups by their TNFα concentration:the high level group(TNFα≥7.95 μg/L,n =313),the moderate level group(TNFα ＞5.34-＜7.95 μg/L,n =268)and the low level group(≤5.34 μg/L,n =313).The selected representative variations were genotyped by TaqMan-PCR in 894 Uygur individuals.The association of the genetic variations of STAMP2 gene with metabolic index and TNFα was analyzed.Results Three representative variations were genotyped,including rs8122,rs1981529 and rs34741656.The genotype distribution and allele frequencies of rs8122and rs1981529 were statistically different among the three groups (P ＜ 0.05),while no difference was observed with rs34741656(P ＞0.05).By ANOVA analysis,statistical difference was showed between the rs1981529 polymorphism AA and AG in the concentration of TNFα(P ＜ 0.05).None of the polymorphisms was significantly associated with TC,HDL-C,LDL-C and TG (P ＞ 0.05).Conclusion Two STAMP2 gene polymorphisms,rs8122 and rs1981529 are associated with the concentration of TNFα in Xinjiang Uygur population.
ABSTRACT
Objective To assess the effectiveness of the quotient of serum sodium to urinary sodium divided by (serum potassium) 2 to urinary potassium (SUSPPUP) in screening for primary aldosteronism (PA).Methods Among 952 patients with hypertension who had renin activity,aldosterone measurements and concomitant serum and urinary biochemistry data,204 patients were diagnosed as cases of PA and 261 as cases of essential hypertension.Diagnosis of PA was made in accordance with established laboratory criteria including renin activity and aldosterone,plasma aldosterone concentration/plasma renin activity (ARR),and saline loading test.The SUSPPUP ratio with the ARR were compared in two groups.Results The area under the curve of SUSPPUP and ARR was 0.797 and 0.796 respectively according to receiver operating characteristic curve,optimal cutoff of SUSPPUP was 1.0,the sensitivity and specificity of SUSPPUP was 98.9％ and 81％ respectively.Conclusions The SUSPPUP ratio is an inexpensive and rapid tool to assess the extent of mineralocorticoid excess,therefore,SUSPPUP ratio can be applied to screen PA in hypertensive patients.
ABSTRACT
Objective To explore an effective mode for the prevention and control of hypertension in agricultural and pastoral areas in Xinjiang by comparing the effect of mode A with that of B in blood pressure-lowering treatment. Methods 1445 patients with hypertension in agricultural and pastoral areas were included in this study. They voluntarily received mode A or B blood pressure-lowering treatment. The changes in heart rate , blood pressure, lipid, and glucose, and the incidences of cardiovascular and cerebrovascular events and adverse events were noted;and the effect of modes A and B was compared. Results 87.07%of the patients chose mode A group, while 12.93%chose mode B. The rate of pressure control was 70.71%in mode A group and 68.75%in mode B group , with no significant statistical difference (P>0.05). In 12th month of treatment, the decreased level of systolic pressure was (19.09 ± 20.33)mmHg in the group with mode A and (14.14 ± 17.85) mmHg in the group with mode B, showing a significant statistical difference between the two groups (P=0.047); and the declined level of diastolic pressure was (11.17 ± 13.23)mmHg and (8.17 ± 11.17) mmHg, respectively, with no significant statistical difference. Conclusion Mode A blood pressure-lowering treatment can effectively control blood pressure in hypertensive patients living in agricultural and pastoral areas in Xinjiang.

ABSTRACT
Objective To explore the lipid metabolism in patients with hypertension and obstructive sleep apnea-hypopnea syndrome.Methods A total of 896 patients (655 cases of male; 241 cases of female) was recruited who were hospitalized in our department,and were classified into four groups based on the finding of polysomnography (PSG):hypertensive without obstructive sleep apnea-hypopnea syndrome (OSAS) (n =243),hypertensive with mild OSAS (n =245),hypertensive with moderate OSAS (n =195),and hypertensive with severe OSAS (n =213).Multiple indices including apnea-hypopnea index (AHI),lowest arterial oxygen saturation(lowest SaO2),body mass index (BMI),blood pressure,total cholesterol (TC),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDLC),triglycerides (TG),fasting blood glucose(FBG),uric acid (UA),and high-sensitivity C-reactive protein(hs-CRP) were assessed,and the relevant risk factors of lipid metabolism were analyzed.Results (1)Male patients had more opportunities to suffer OSAS than female (P ＜0.01).Compared with the group without hypertensive,patients in severe OSAS group had higher levels of AGE (48.09 ± 9.48,BMI (29.46 ±3.83),AHI[45.90(37.55,63.65)],MSpO2 (89.08 ±4.93),LSpO2 (67.36 ± 12.60),TC (4.68 ±1.00),TG[2.03(1.54,2.88)],UA (371.85 ±99.29),and hs-CRP[1.43(0.82,3.056)] (P ＜0.05),and had lower levels of HDL-C (1.09 ± 0.28).(2) Two and more than two lipids abnormal metabolic indices increased prevalence with the increase of the severity of OSAS.(3)The prevalence of high TG,high TC in AHI ≥ 15/h was significantly higher than AHI ＜ 15 group.(4) After adjustment for BMI,gender,age and other common risk factors,it confirmed that AHI was still related to lipid metabolism.AHI was an independent risk factor for abnormal lipid metabolism.Conclusions AHI was an independent risk factor for abnormal lipid metabolism.With increasing severity of OSAS,the levels TC,TG,and the category of abnormal lipid metabolism were also increased.
ABSTRACT
One hundred and fifty-six patients with primary aldosteronism(PA)and 189 patients with essential hypertension (EH) were included in this study.The value of estimate glomerular filtration rate (eGFR) was calculated by MDRD equation.The plasma levels of aldosterone,triglycerides,creatinine and fasting glucose were measured.The plasma creatine,24 hour urine albumin excretion in PA patients were higher and eGFR and plasma aldosterone were lower than those in EH patients ( all P ＜ 0.01 ).Multiple regression analysis revealed that the plasma concentrations of aldosterone ( P =0.003 ) and creatinine ( P =0.001 ) were independent predictors of eGFR.
ABSTRACT
ObjectiveTo investigate the characteristics of left ventricular structural damage in patients with primary aldosteronism(PA).MethodsA total of 438 inpatients with hypertension from January 2007 to June 2010 were screened for PA,and diagnosis was made in 213 PA patients and 225 patients with essential hypertension (EH).The left ventricular structure of all subjects was evaluated according to the results of echocardiographic measurements.Results The duration of hypertension and plasma aldosterone level in patients with PA were significantly higher (P＜ 0.01 ),while the serum potassium and plasma renin activity were significantly lower (P＜0.01 ) than those in patients with EH.The interventricular septum thickness,left ventricular end-diastolic dimension,left ventricular mass index (LVMI),left ventricular end-diastolic volume,and stroke volume in patients with PA were significantly higher than those in EH patients( P＜0.01 ) after the duration of hypertension was corrected.In patients with PA,the prevalence of left ventricular hypertrophy (LVH) was higher than that in EH patients ( 53.1％ vs 33.8 ％,x2 =16.57,P ＜ 0.01 ). Normal left ventricular geometry ( NG ),concentric remodeling ( CCR ),concentric hypertrophy( CCH),and eccentric hypertrophy (ECH) were found respectively in 24.9％,22.1％,22.1％,and 30.9％ of patients with PA.Multiple stepwise regression analysis showed that the seated plasma aldosterone level (β=0.43,P ＜ 0.01 ) and systolic blood pressure (β =0.45,P ＜ 0.01 ) were the main factors that influenced LVMI.The course was the main parameter that influenced relative wall thickness(β=0.011,P＜0.05 ).Conclusion The prevalence of LVH is higher in patients with PA than that in EH patients.The eccentric hypertrophy is the most common left ventricular geometrical pattern in patients with PA.
ABSTRACT
The clinical data of 330 patients with primary aldosteronism (PA) from January 2006 to March 2010 were retrospectively analyzed. The prevalence of 1, 2, and 3 stage hypertension in these subjects was 3.64％,20. 91％, and 75.45 ％, respectively. Of all PA patients, 89.09％ were young adults and 81.82％ were overweight or obese. There was a marked preponderance of male patients in the overweight or obese group ( P＜0. 01 ). The incidence of hypokalemia was 32. 12％. The concentration of serum potassium was not associated with the disease course. Logistic regression showed that the concentration of plasma aldosterone was an independent risk factor of hypokalemia in PA patients( P＜0. 01 ). 79. 09％ PA patients presented the plasma aldosterone level over 12 ng/dl and the renin activity level of less than 1 ng · ml-1 · h-1. The aldosterone-to-rennin activity ratio was ＞20 in 94.24％ of the patients with PA.
ABSTRACT
Objective To investigate the association between the obstructive sleep apnea-hypopnea syndrome(OSAHS) in hypertension and insulin.Methods A total of 521 patients were divided into 4 groups according to apnea-hypopnea index and OSAHS degrees.The control group ( group Ⅰ ),mild OSAHS group ( group Ⅱ ),moderate OSAHS group ( group Ⅲ ) and severe OSAHS group ( group Ⅳ ) had 89 patients,194 patients,118 patients and 120 patients respectively.Results The BMI[( 30.4 ± 3.8 )kg/m2],apnea-hypopnea index ( AHI,3.8 ± 0.1 ),Fasting insulin (FIns)[(3.08 ± 0.26 ) mU/L]and insulin resistance ( 2.43 ± 0.27 ) of patients in severe OSAHS group were significantly higher than that of in the control,mild OSAHS group and moderate OSAHS group ( P ＜ 0.01 ).The levels of saturation of minimum oxygen from skin of patients in severe OSAHS group was significantly lower ( MSpO2 ) than in that of the control,mild OSAHS group and moderate OSAHS group.Multiple linear regression analysis showed that fasting plasma insulin and insulin resistance was positive correlation with apnea-hypopnea index,while they also negatively associated with saturation of minimum oxygen.Conclusions FIns and insulin resistance strongly associate with AHI and levels of saturation of minimum oxygen from skin.Hypertensive patients with OSAHS have more chances to suffer with insulin resistance.
ABSTRACT
Objective To study the linguistic manifestations and locations of brain lesions of Uyghur aphasia patients,and the differences between Uyghurs and other Chinese aphasics.Methods Forty-five aphasic Uyghurs and forty-five other Chinese aphasies were studied.All had suffered a stroke.Aphasia examinations were performed using a Chinese aphasia battery(ABC).CT and MRI images were taken of all patients.Results There was no obvious difference in linguistic manifestations between the Uyghur and other aphasics.The brain lesions of 24 Uyghur cases(53.33％)and 36 of the others(80％)were located in the classic language centers,a highly significant difference.The incidence of crossed aphasia in the Uyghur group was higher than among the others.Conclusion Various types of aphasia have their own unique linguistic characteristics,but the same type of aphasia has the same linguistic characteristics among Uyghurs and other Chinese.Chinese aphasia is more coincident with the pattern of classic language centers than aphasia among Uyghurs.

ABSTRACT
Objectives To investigate the relationship between obstructive sleep apnea hypoventilation syndrome (OSAHS), insulin resistance (IR) and metabolic syndrome (MS), as well as to explore the possible mechanism of MS caused by OSAHS. Methods We recruited 186 hospitalized patients with hypertensions, who were divided into four groups based on their nocturnal polygraphs recordings, 35 as controls (group Ⅰ), 61 with mild (group Ⅱ), 52 with moderate (group Ⅲ) and 38 with severe OSAHS (group Ⅳ). They all underwent measurements including body height, body weight, waist circumference (WC), systolic and diastolic blood pressure (SBP and DBP), serum uric acid, creatinine, fasting plasma glucose, fasting plasma insulin, serum total cholesterol, high-density lipoprotein-cholesterul, low-density lipoprotein-cholesterol and triglyceride. Results One hundred and two patients with OSAHS (67.6 percent) also suffered of MS, 33 (86.8 percent) of them with severe OSAHS. There was no significant difference in age, gender, fasting plasma glucose, total cholesterol, high-density lipoprutein-cholesterul, low-density lipoprotein-cholesterol and triglyceride among the four groups (P>0.05). Body mass index (BMI), WC, ratio of serum uric acid to creatinine and DBP were all significantly higher in patients with severe OSAHS than those in patients with mild and moderate OSAHS and controls (P<0.01). SBP was significantly higher in patients with severe OSAHS than that in those with mild and moderate OSAHS (P<0.01). Insulin resistance was significantly severer in patients with severe OSAHS than that in those with mild OSAHS and controls (P<0.01). Results of multivariate linear regression analysis showed that insulin resistance was correlated with BMI and reversely correlated with minimal blood oxygen saturation, and minimal blood oxygen saturation reversely correlated with WC and ratio of uric acid to creatinine. Condusions Hypoxemia and obesity may promote development of insulin resistance. Patients of hypertension complicated with OSAHS tend to develop MS, particularly in those with severe OSAHS.
