Objective:To observe the influence of long-term exercise training on carotid intima-media thickness (IMT)in patients with mild-to-moderate hypertension.Methods:A total of 92 patients with mild-to-moderate es-sential hypertension (EH)were randomly and equally divided into exercise group and routine treatment group.Exer-cise group received exercise training based on routine treatment.All patients were followed up one year.Influence of long-term exercise training on carotid artery diameter and carotid IMT was observed in EH patients.Results:Af-ter one year,there were significant reductions in systolic blood pressure (SBP),diastolic blood pressure (DBP),ca-rotid artery diameter and carotid IMT in both groups,P<0.05 all;compared with routine treatment group,there were significant reductions in SBP [(145.72±11.31)mmHg vs.(130.89±13.01)mmHg],DBP [(88.49±7.32) mmHg vs.(81.71±8.45)mmHg],carotid artery diameter [(6.34±1.23)mm vs.(6.22±1.01)mm]and carotid IMT [(0.89±0.21)mm vs.(0.84±0.11)mm]in exercise group after treatment,P<0.05 all.Conclusion:Long-term exercise training can effectively reverse early arteriosclerosis lesion of carotid wall and effectively control blood pressure.

AlM:To investigate the visual function in myopia and hyperopia amblyopia whose corrected visual acuity have recovered to normal.METHODS: The visual function of children ( 50 cases ) with amblyopia eyes by binocular vision correction after treatment above 0. 9 was checked. The simultaneous perception, fusion range and distance stereopsis were measured. According to the refractive condition of the children who were divided into group A ( myopia, 20 cases ) and group B ( hyperopia, 30 cases ) . The statistically difference of simultaneous perception, fusion function and stereopsis in two groups was analyzed. RESULTS: Fifteen ( 75%) and twenty - six ( 87%) children got the simultaneous perception in group A and group B respectively, and the differences between two groups were not significant (χ2=0. 454,P>0. 05). Group A had six children ( 30%) and group B had only seven children (23%) with the normal aggregative fusion range, two groups did not show any difference (χ2 =0. 565, P>0. 05). Respectively sixteen (80%),and twenty children ( 67%) had the normal divided fusion range in group A and group B, the recovery rate did not show any significant difference (χ2=0. 740, P>0. 05). Fifteen (50%) and seven ( 35%) patients acquired the far stereoscopic vision in group B and group A respectively, the recovery rate also did not show any significant difference. Normal distance stereopsis of 50 cases had 22 cases ( 44%) , and normal near stereopsis of 50 cases had 13cases ( 26%) Seven (23%) and 6 (30%) children got the normal near stereoscopic vision in group B and group A respectively, and the recovery rate did not show any significant difference (χ2=0. 195, P>0. 05;χ2=0. 295, P>0. 05).CONCLUSlON:After amblyopia treatment, although the children got the normal visual acuity, the binocular vision still can not completely normal in the short term. Myopia and hyperopia factor will not produce significant effect on binocular vision development.

Background Diabetic retinopathy (DR) is one of the most important microvascular complications of diabetes,which has become one of the leading causes of blindness.Neovascularization is the main pathological manifestations of DR,but its mechanism is unknown.There is a clear need to investigate its pathogenesis which can offer potential therapeutic targets.Objective The aim of this study was to investigate the expression and distribution of visfatin and vascular endothelial growth factor (VEGF) in diabetic model rats.Methods This study was approved by Animal Ethic Committee of Inner Mongolia Medical University.Sixty SPF 8-week-old male SpragueDawley rats were randomized into the diabetic group and control group.The rats were housed under a condition that alternated between 12 hours of light and darkness,with free access to rat food and water.Diabetes was induced by intraperitoneal injection of 60 mg/kg (0.60 ml/100 g) of streptozotocin (STZ) and control rats received equivalent volume of buffer.The models were regarded as successful when blood glucose was ≥ 16.7 mmol/L.Rats were sacrificed 12 weeks after the injection of STZ and retinal specimens were prepared to detect the expression of visfatin and VEGF.Total retinal protein was isolated from the retinas of experimental and control eyes,and the expression of visfatin and VEGF was assessed by Western blot.Frozen cross sections of retinas of 5 μm thickness were used to perform double immunofluorescence staining with anti-visfatin and anti-VEGF antibodies.Results Mean body weight of the diabetic rats was (189.02±11.34) g and that of the control rats was (489.57 ± 14.48) g at 12 weeks post-injection,showing a significant difference between them (t =5.236,P =0.003).Mean blood glucose level was (29.25±3.86) mmol/L in the diabetic group and (5.32±1.01) mmol/L in the control group,demonstrating a significant difference (t =11.778,P =0.000).Double immunofluorescence staining showed reduced expression of visfatin and VEGF in the retinal nerve fibrous layer and glial cells in the control rats.A stronger staining for visfatin and VEGF was found in the various layers of the retina in the diabetic rats,with an expression level of visfatin (A value) of 346.26±41.23,which was considerably higher than that of the control group (102.07±65.01) (t =8.291,P =0.000) in 12 weeks after injection.Furthermore,the expression of VEGF in the retina was elevated in the diabetic group compared with the control group (A value) (415.88±92.15 vs.113.06±32.06) (t=10.067,P=0.000).Conclusions Visfatin might contribute to the pathologic progression of diabetic retinal,neovascularization and it might play a synergistic role with VEGF in the pathophysiology of DR.

Background:The incidence of ulcerative colitis (UC)in developed countries is higher than that in developing countries,which may be related with westernized lifestyle,especially high animal protein and low complex carbohydrate diet. With the increased high fat and meat intake,synthesis and secretion of bile acid in liver is also increased,which may have an impact on the occurrence of UC. Aims:To investigate the expressions of farnesoid X receptor (FXR)and G protein-coupled bile acid receptor 5 (TGR5)in patients with UC. Methods:Thirty patients with active UC from January 2013 to June 2016 at the Affiliated Jiangning Hospital of Nanjing Medical University were enrolled,and 30 healthy subjects were served as controls. Expressions of FXR and TGR5 were determined by immunohistochemistry. Results:Compared with control group,expression of FXR was significantly decreased in UC patients (4. 63 ± 2. 07 vs. 6. 91 ± 2. 62,P =0. 00),however,no significant difference in expression of TGR5 was found between the two groups (6. 70 ± 2. 90 vs. 6. 11 ± 2. 44,P = 0. 40). Expression of FXR was significantly increased in right hemicolon colitis than in left hemicolon colitis (P < 0. 05). Conclusions:There is a significant decrease in FXR in active UC patients,indicating that FXR may have some role in the pathogenesis of UC,however,TGR5 may have no obvious effect in the pathogenesis of UC.

Objective To investigate the relationship between satisfaction of nursing service and nurses' personality and mental state.Methods 368 nurses ,288 patients and 234 dependents involved the investigation.Minnesota Multiphasic Personality Inventory(MMPI)was used to analyze nurses' personality.Symptom Checklist-90(SCL-90),Self-rating Depression Scale(SDS) and Self-rating Anxiety Scale(SAS)were used to analyze nurses' mental states.A self-made questionnaire on satisfaction was used to investigate the satisfaction degree of patients and dependents with nursing service.The data were analyzed by descriptive statistics and multiple regression analysis.Results The average score on satisfaction with the nurses' service was(8.29±0.98)and the average score on satisfaction with nurses' attitude was(8.19±1.21).The satisfaction with nurses' service was negatively correlated with the MMPI factors of manifest anxiety and dependency and positively with dominance of MMPI(both P<0.05).Satisfaction with nurses' attitude was negatively correlated with total score of SAS,dependency of MMPI,compulsion,anxiety,hostility and paranoid ideation of SCL-90(all P<0.05).Satisfaction with the service attitude was positively correlated with social responsibility of MMPI(P<0.05). Conclusion Satisfaction degree of patients and their dependents is related to nurses' personality and mental states.It's helpful to establish good relationship between nurses and patients and improve the clinical nursing service to perfect nurse's personality and relieve psychological stress on nurses.

BACKGROUND: The effective therapy of artificial liver for severe hepatitis needs an absorbing material which possesses strong adsorptive property, high adsorption rate and good blood compatibility.OBJECTIVE: To study the adsorptive property of eight novel adsorbents for plasma bilirubin and cytokines in severe hepatitis patients. DESIGN: A controlled observation.SETTINGS: Graduate School of Tianjin Medical University, Tianjin Haihe Hospital, Tianjin Third Central Hospital and the Institute of Polymer Chemistry in Nankai University.PARTICIPANTS: All plasma was collected from 30 severe hepatitis patients hospitalized in Tianjin Third Central Hospital from November 2004 to November 2005. Informed consent was obtained from each patients. This experiment was approved by the hospital ethical committee. All the patients were divided into two groups at random: group 1 (n=10) and group 2 (n=20). The level of total bilirubin (TBiL) before therapy in two groups was (377.3±147.5) μmol/L and (327.6±140.1) μmol/L, respectively.METHODS: ①Adsorbents: Chitosan (Qingdao Lizhong Chitosan Factory, Shandong) with relative molecular weight 97 000 and de-acetyl grade 85%; Adsorbents No.1-3 were prepared by using 1%, 3%, 5% polyethyleneglycol (relative molecular weight 600) as porogenic agent. Adsorbent No.4 was aminated crosslinked chitosan microspheres; Adsorbent No.5 was divinyl-benzene crosslinked macroporous polystyrene microspheres; Adsorbent No.6 was post-crosslinked macroporous divinyl-benzene styrene copolymer microspheres; Adsorbents No.7 and 8 were chitosan wrapped adsorbent No.5 and 6.②Detection: Step 1: 3 mL plasma collected from each severe hepatitis patient in group 1 was absorbed with 1 mL of 8 kinds of adsorbents. Levels of plasma TBiL, direct bilirubin (DBiL) and indirect bilirubin (IBiL) before and after adsorption were determined by using the vanadate oxidation method to analyze the average adsorption capacity so as to screen the adsorbents with the better adsorptive properties. Step 2: 3 mL plasma collected from each severe hepatitis patient in group 2 was absorbed with 1 mL of two adsorbents selected from the step 1. The levels of bilirubin, interleukin-6 and tumor necrosis factor-α before and after the adsorption were analyzed by ELISA method.MAIN OUTCOME MEASURES: The levels of bilirubin and cytokines before and after the adsorption were determined.RESULTS: ①The data in the first step experiment showed that after No.4 and No.5 adsorbents were used, the level of plasma TBiL, DBiL and IBiL were significantly decreased (P < 0.01); no differences were found for other six kinds of adsorbents (P > 0.05).②The data in the second step experiment showed that the average levels of plasma TBiL, DBiL, IBiL, interleukin-6 and tumor necrosis factor-α were remarkably reduced after using adsorbents No.4 and No.5 (P < 0.01). Compared with adsorbent No.5, there were significant decrements for adsorbents No.4 (P < 0.01).CONCLUSION: Aminated chitosan microsphere has significant effects on adsorbing bilirubin and cytokines in plasma of severe hepatitis patients in vitro.

Objective To study the immune regulation of antisense peptide in rats by observing immune function of activity fragments of thyrotropin receptor (TSHR) and their corresponding antisense peptides. Methods TSHR peptides TR1, TR2, TR3 and their antisense peptides RT1, RT2, RT3, and three pairs of complementary peptides were injected into rats of different groups respectively, and the serum levels of TT_3, TT_4, TSHR antibody (TRAb), thyroid stimmulating antibody, thyroid blocking antibody and TSH antibody (TSHAb) and pathological changes in thyroid tissue were investigated. Results Serum TRAb could be induced when each of three fragments of TSHR was injected into rats; TRAb and TSHAb were induced by RT1 or RT2; epithelial hyperplasia and lymphocytic infiltration observed in thyroid tissue of rats injected with TR2 could be abated by injecting RT2 subsequently. Conclusion The results suggest that all 3 TSHR fragments are shown to be immunogenic and are capable to induce TRAb; both RT1 and RT2 show their effect on immune regulation and are idiotypic of TSHR peptides; On the other hand, the humoural and cell immunities are ameliarated by injection of antisense peptides. Therefore, it is possible that antisense peptides may be involved in immune regulation via immune network.
