Objective To investigate the changes of the hemostatie coagulation markers in pregnancy induced hypertension (PIH)and significance.Methods The blood samples were collected from 70 normal pregnant women (control group) and 66 pregnant women with PIH (PIH group).Platelet count (PC), mean platelet volume ( MPV ), prothrombin lime (PT), partial thromboplastin time (AFIT), fibrinogen (FIB),D-dimmer (D-D)were measured.Results Compared with the control group,the level of PC,PT, APTT in the PIH group were significantly decreased [(178.32±51.08) × 10~9/L vs (186.17±40.02) × 10~9/L, (10.54±0.34) s vs(11.07±0.49) s, (26.23±3.12) s vs(28.08±4.31) s](P<0.05 or <0.01), while those of FIB,MPV,D-D were significantly increased [(5.34±0.68) g/L vs (4.02±0.73) g/L, (11.10 ± 2.31 ) fl vs (8.95 ± 1.37) fl, (0.46 ± 0.27) mg/L vs (0.18 ± 0.19) mg/L](P < 0.01 ).The levels of FIB and D-D were significantly increased in severe preeclampsia (34 cases) than those in mild preeclampsia (32 cases) (P < 0.01 ).The level of PT was lower and FIB, D-D were increased in early onset preeclampsia ( 31 cases ) than those in late onset preeclampsia (35 cases) (P < 0.05 or < 0.01 ).Conclusions There is hypercoagulative state in pregnant women with PIH.The disorders of coagulation function may be more severe in early onset preeelampsia than those in late onset preeclampsia.

Objective To investigate of mental health level and coping style in emergency nurses. Methods Investigations were conducted in 78 emergency nurses who had been m the emergency department over one year from 4 general hospitals in Huizhou using general condition questionnaire, symptom checklist 90 (SCL-90) and simple coping style questionnaire, the results underwent analysis. Results The subfactor score of SCL- 90 was significantly higher than that of Chinese norm. Emergency nurses adopted positive coping style more then conunon adillt group. The positive coping style of nurses was negatively correlated with the total score of SCL-90, somatization, interpersonal relationship, depression and anxiety factor of SCL-90. The negative coping style was positively correlated with the total score, sornatization, depression and anxiety factor of SCL-90.Conchusions Emergency nurses have poor mental health. We must adopt effective means to improve theirs mental health level.

Objective To estimate the effect of tretinoin gel sheeting on early-stage hyperplastic scars in rabbit ears,and to evaluate the feasibility to prevent and treat hyperplastic scars with it.Methods The ears of 24 rabbits were used to establish a model of hyperplastic scar according to previously reported methods.Then,the rabbit ears were randomly divided into four groups:control group receiving no treatment,gel sheeting group treated with the vehicle of the tretinoin gel sheeting,0.05％ tretinoin group treated with 0.05％ tretinoin gel sheeting,0.1％ tretinoin group treated with 0.1％ tretinoin gel sheeting.All the gel sheetings were topically used twice daily for six consecutive weeks.During the treatment,the size,thickness,color and texture of scars were estimated.After six weeks of treatment,all the scar tissues were resected from the rabbit ears and subjected to hematoxylin and eosin (HE) staining and van Gieson (VG) staining.Statistical analysis was carried out by analysis of variance and rank sum test.Results The scars were deeply colored,thickened,hard and elevated with an uneven surface in the control group,but lightly colored,thinned and soft with the presence of small subcutaneous nodules in the other three groups.The surface of scars in the two tretinoin groups was similar to that of adjacent normal skin,and scaling was observed on the scar surface in the 0.1％ tretinoin group.HE and VG staining showed a disarrangement of collagen fibers with the formation of vortex-like structures in the control group.A significant decrease was noted in the number of fibroblasts and microvessels as well as amount of collagen deposition per unit cross-sectional area in the two tretinoin groups compared with the control group and gel sheeting group.Additionally,the collagen fibers were regularly arranged and parallel to the long axis of scars in the two tretinoin groups.The scar hyperplasia index (HI) was 3.173 ± 0.26,2.465 ± 0.19,1.906 ± 0.21 and 1.903 ± 0.23 in the control group,gel sheeting group,0.05％ tretinoin group and 0.1％ tretinoin group respectively,the fibroblast density (NA) was 5836.7 ± 527.03,4128.73 ± 387.66,3207.59 ± 439.17 and 3200.28 ± 421.48 respectively,and the area density of collagen fiber (AA) was 45.38 ± 5.83,36.57 ± 6.84,28.09 ± 3.82 and 28.07 ± 3.47 respectively.As far as HI,NA and AA were concerned,the control group differed significantly from the other three groups (all P ＜ 0.01),and the gel sheeting group from the two tretinoin groups (all P ＜ 0.01),but no significant difference was observed between the two tretinoin groups (all P ＞ 0.05).Conclusions Topical tretinoin gel sheeting can inhibit scar proliferation at early stage in rabbit ears,and may provide a new choice for the prevention and treatment of hyperplastic scars.

Objective To investigate the expression of XIAP and survivin and its significance in diffuse large B-cell lymphoma. Methods The expression of XIAP and survivin were detected by immunohistochemistry in 49 patients with diffuse large B-cell lymphomas. Results The positive rate of XIAP and survivin in cases of DLBCL were 40.8%(20/49) and 44.9%(22/49) respectively, which was higher than that of benign lymph node pathological changes (P ＜0.05). The expression of XIAP in DLBCL positively correlated with the expression of surviving (r =0.382, P =0.01). Moreover, the mean survival period in DLBCL expressing XIAP was shorter than the XIAP-negative group. Conclusion The up-regulation of expression of XIAP may play an important role in the development of DLBCL, and may cooperate with the expression of survivin in apoptosis pathway. Furthermore, the expression of XIAP might be a new unfavorable prognosis factor of DLBCL.

Objective To investigate the expression of NF-κB/p65 in nasal NK/T cell lymphomas. Methods Immunohistochemis-try and TUNEL were used to study the expression of NF-KB/p65 and cell apoptosis in 23 nasal NK/T cell lymphoma samples and 14 benign lymph node lesions. Results The NF-KB/p65 positive rates were 43.5% (10/23). The expression of NF-κB/p65 was negative correlated with apoptotic index among 23 nasal NK/T cell lymphomas(P <0. 05). The mean survival period in patients expressed NF-KB/p65 was sig-nificantly shorter than that in negative group(P <0. 05). Conclusions Apoptosis inhibited by overexpression of NF-κB/p65 might be in-volved in the development of nasal NK/T cell lymphoma. NF-κB/p65 expression may be an unfavorable prognostic factor of nasal NK/T cell lymphoma.

Objective To explore the effect of family visit and nursing intervention in promoting the re-habilitation of thoracolumbar fracture patients. Methods 115 patients with thoracohmbar fracture were divid-ed into the study greup(60 cases) and the control group(55 cases) by random hospitalization number. Patients in the study group were given regularly rehabilitation guidance initiatively at home by doctors and nurses for 6 months since discharge, the control group received conventional discharge guidance. Results After the inter-vention, the two groups showed significant difference in the functional rehabilitation, awareness rate of disease-related knowledge, mastering rate of relevant skills, incidence rate of complication, satisfaction degree with nursing. Conclusions Regular family visit and nursing intervention by the doctors and nurses can not only teach patients relative functional exercise methods, promote the physical rehabilitation of limbs, reduce inci-dence of complications and solve the problem of lack of care support after discharge from hospital effectively.

Objective To investigate the expression of IgG4 in liver tissues of patients with type Ⅰ autoimmune hepatitis (AIH) and to analyze the clinical manifestation,biochemical indexes,immunological genetic features,pathological characteristics and the effects of immunosuppressive therapy.Methods From March 2012 to July 2013,45 patients diagnosed as type Ⅰ AIH were enrolled.Immunostaining of CD38,IgG and IgG4 in liver tissue slices was performed,inflammation grade G and fibrosis stage S were determined.At the same time,serological indexes (alanine aminotransferase (ALT),aspartate transaminase (AST),alkaline phosphatase (ALP),IgG,antinuclear antibody (ANA) titer,antibodies to asialoglycoprotein receptor (ASGPRAb)) of the patients were collected,serum IgG4 was tested and the response to immunosuppressive therapy was observed.Wilcoxon rank sum test and t test were performed for quantitative data comparison.Spearman correlation coefficient was used for correlation analysis.Results Among 45 patients with type Ⅰ AIH,five patients (11.1％) were IgG4 associated AIH (IgG4-AIH group).There were no significant differences in age,gender,biochemical indexes (serum levels of ALT,AST,ALP),immunity indexes (serum levels of IgG,ANA titer,ASGPRAb) and degree of liver fibrosis between patients with IgG4-associated AIH and classical AIH (40 cases) (all P＞ 0.05).Compared with classical AIH group (18.3(6.7) mg/L).The serum level of IgG4 of IgG4 AIH group was 25.8(9.2) mg/L,which significantly increased (Z=-2.041,P＜0.05).However,there was no significant difference in serum level of IgG4 between the two groups (P＞0.05).There was no correlation between the number of infiltrated IgG4 positive plasma cells and the serum level of IgG4 (r=0.311,P=0.279).The inflammation in the liver tissues of IgG4-AIH group was more significant compared with that of classic AIH group (H=4.120,P＜0.05).The number of CD38' or IgG+ plasma cells was larger compared with that of classical AIH (CD38(39.3(13.5)/high power field (HPF) vs (21.3(8.8))/HPF,IgG(39.3 (14.0))/HPFvs (18.5(8.9))/HPF;Z ＝-3.561 and-3.584,both P＜0.01).The number of IgG4+ plasma cells in liver tissues was positively correlated with the number of CD38+ or IgG+ plasma cells (r=0.884 and 0.791,both P＜0.01).Conclusions Among patients with type Ⅰ AIH,the incidence of IgG4-associated AIH was not high.The serum level of IgG4 did not significantly increase in these patients.However,the histological inflammation activity was significant along with many CD38+ or IgG+ plasma cells infiltration.
