Objective To analyze the blood pressure,heart rate,the US national institutes of health stroke scale(NIHSS) score,Glasgow coma scale(GCS) score for cerebral infarction patients with cerebral hemorrhage after recombinant human tissue-type plasminogen activator (rt-PA) therapy.Methods From April 2011 to April 2013,48 cases with cerebral infarction after intravenous rt-PA thrombolysis were collected.These cases were divided into two groups:the first group (32 cases):without cerebral hemorrhage after thrombolysis; the second group (16 cases):with cerebral hemorrhage after thrombolysis.The systolic blood pressure,diastolic blood pressure,heart rote,NIHSS score and GCS score were compared between the two groups before and after thrombolysis.Results After thrombolysis,the systolic and diastolic blood pressure were significantly increased in cerebral hemorrhage cases compared with before thrombolysis and patients without cerebral hemorrhage.After thrombolysis,the NIHSS score was significantly reduced in the cases without cerebral hemorrhage compared with that before thrombolysis,while the NIHSS score was significantly higher in the cases with cerebral hemorrhage compared with that before thrombolysis.After thrombolysis,the heart rate and GCS score showed no significant difference between the patients with and without cerebral hemorrhage.Conclusions The rising of systolic blood pressure,diastolic blood pressure and NIHSS score helps us determine the early cerebral hemorrhage after thrombolysis in cerebral infarction patients.

Objective To investigate the expressions of human papillomavirus (HPV) 16E6 and E-cadherin in different cervical tissues.Methods Immunohistochemistry expressions of HPV16E6 and E-cadherin were analyzed in 30 normal cervical tissues,34 cervical intraepithelial neoplasias (CIN),and 60 squamous cervical cell carcinomas.Results The differences in positive expression rates of HPV16E6 and E-cadherin were statistically significant among normal cervical tissues,CIN Ⅰ,CIN Ⅱ-Ⅲ,cervical squamous cell carcinomas (x2 =40.166,P =0.000;x2 =31.295,P =0.000),respectively.The abnormal expressions of HPV16E6 and E-cadherin expression were significantly related to clinical pathological stage,tumor size,histological grade,invasion depth of squamous cervical cancers (P ＜ 0.05),but not correlated with age (P ＞0.05).The expressions between HPV16E6 and E-cadherin protein were negatively correlated (rs =-0.647,P =0.000).Conclusions There may be relationship between HPV16E6 and E-cadherin,and the abnormal expressions of two proteins may be associated with poor prognosis of cervical carcinomas.

[ Abstract]Objective To investigate the effect of two-tage skin grafting with artificial dermis for perianal hidradenitis suppurativa. Methods A total of 20 cases diagnosed as perianal hidradenitis suppu-rativa in our hospital were selected from 2011 to 2013. In the first-stage operation,all diseased skin inclu-ding the superficial subcutaneous fatty tissue was excised,and normal deep subcutaneous fatty tissue was preserved. Then,artificial dermis was grafted to the preserved fatty tissue. After two weeks,split-hickness skin grafts were used for the skin defects as the second-tage operation. Graft success,recurrence and post-operative appearance were evaluated in these patients who were followed up for 9 to 28 months. Results Skin grafts of all 19 patients were successfully survived. The recurrence of hidradenitis suppurativa oc-curred in only one patient. This patient was treated with reoperation and the postoperative appearance was welly recovered. Conclusion Two-tage skin grafting with artificial dermis appears to be a good treatment option for perianal hidradenitis suppurativa.

Objective To investigate the effect of neutrophil activation on pathogenesis of preeclampsia. Methods In 22 pregnant women with preeclampsia and 21 normal pregnant women at third trimester, neutrophil activation was examined by flow cytometry to assess the CD11b expression,and the levels of plasma endothelin 1(ET 1) and serum NO - 2 were also measured with no equilibrium radio immunoassay and with Griess assay respectively. Results The expression of neutrophil CD11b was significantly elevated in women with preeclampsia compared with that of normal pregnant women at third trimester [the mean fluorescence index of CD11b were 439 1? 169 1 and 321 2?166 3 respectively, P0 05). Conclusions The neutrophil CD11b expression is significantly elevated in preeclampsia. The increased neutrophil activation may cause the damage of vascular endothelium and result in compensatory increase of NO release in endothelial cells. It suggests that the neutrophil activation may play a key role in pathogenesis of preeclampsia.

Objective To investigate the disease causing gene of Stargardt disease. Method Fifteen patients with Stargardt disease were analyzed with 11 primers of the 11 exons of ABCR gene by using PCR SSCP and DNA direct sequencing techniques. Results Three newly detected disease causing mutations were found. Among those mutations, one is a frameshift mutation and others are single base transition. Conclusion This research confirmed that ABCR gene is associated with Stargardt disease, and 3 new mutations of ABCR gene were found.

Objective To study the effect of anti anxiety treatment in residual dizziness after successful canalith repositioning procedure in benign paroxysmal positional vertigo.Methods 68 cases of benign paroxysmal position vertigo patients with residual dizziness after successful canalith repositioning procedure were collected,who visit department of Neurology..They were randomly assigned to anti anxiety group and the control group according to randomized controlled method.Deanxit (0.5mg/10mg,1times/day)combined with betahistine mesilate tablets (6mg, 3 times/day)were taken by patients in the anti anxiety group;take betahistine mesilate tablets (6mg,3 times/day) were taken in the control group.Follow up 3 months,the duration of residual dizziness and the changes of symptoms between the two groups were compared.The symptoms of all patients were evaluated before and after treatment by dizziness handicap inventory.Results The duration of residual dizziness in the control group was (16.38 ±8.83)days, and that in the anti anxiety group was (10.13 ±5.10)days.The duration of residual dizziness in the anti anxiety group was significantly shorter than that in the control group (t =3.440,P <0.05).In the control group,the scores of first week,s econd week and third week were (26.60 ±13.54)points,(20.80 ±10.97)points and (6.27 ±5.88)points.In the anti anxiety group,the scores of first week,second week and third week were (23.10 ±11.02)points,(13.33 ± 5.83)points and (0.67 ±2.50)points.There was not significant difference between the two groups (t =1.122,P >0.05)in the treatment of first week.In second week and third week,the scores of the anti anxiety group were lower than those of the control group,the differences were statistically significant (t =3.378,4.935,all P <0.05).After 3 weeks of treatment,the scores of the anti anxiety group were significantly decreased in the functional,emotional and physical scores (t =5.297,4.537,4.451,all P <0.01 ).Conclusion Deanxit can shorten residual dizziness duration of benign paroxysmal position vertigo patients after successful canalith repositioning procedure,and can reduce the degree of residual dizziness.

Objective To investigate plasma homocystein (Hcy) level in cardiac transplant patients.Methods Fourteen cases of heart transplant patients were recruited in this study. Plasma Hcy levels were measured by using high-performance liquid chromatography with fluorescence detection and flow-mediated dilatation in brachial arteries detected with high-resolution ultrasound in all patients, while coronary artery angiography were performed in 7 patients.Results In 2 cases of heart transplant who had single coronary artery stenosis, the plasma Hcy levels were above 12 ?mol/L. The average plasma Hcy levels in heart transplant patients were higher than in health volunteers [( 13.47? 2.78) ?mol/L vs (9.26? 3.57) ?mol/L], and flow-mediated dilatation in brachial arteries of heart transplant patients was lower than that of health volunteers [( 8.2? 3.7) % vs ( 12.5? 1.6) %]. There was a linear correlation between levels of plasma Hcy and flow-mediated dilatation (r= -0.804). Conclusion Endothelial dysfunction in the heart transplant patents might be contributed to hyperhomocysteinemia which may be potential cause of transplant coronary artery disease.
