Methods IMT, FFA and body mass index (BMI) were measured in 69 hypertensive patients with metabolic syndrome (MS group) ,57 hypertensive patients without metabolic syndrome ( Non-MS group) ,and 50 healthy controls ( NC group). Results In the MS group,The BMI, serum levels of triglyceride (TG), fasting blood glucose (FPG) and FFA were ( 26.0 ± 2.1 ) kg/m2, (24.0 ±0.81 ) mmol/L and (5.64 ± 0.82) mmol/L respectively, which were significantly higher than those in the Non-MS group ( (24.9 ± 2.3 ) kg/m2, ( 1.93 ± 0. 55 ) mmol/L and ( 5.10 ± 1.08 ) mmol/L respectively ) and the NC group ( (23.6 ± 1.6), ( 1.49 ± 0.36) mmol/L and (4.70 ± 0.90) mmol/L respectively) ( F = 20.06, 30.96 and 15.17,P ＜0.05 or 0.01 ). FFA in the MS group ((562.11 ± 55.12)μmol/L) were significantly higher than that in the Non-MS group (402.65 ± 49.53 ) μmol/L) and the NC group ( ( 356.23 ± 45.93 ) μmol/L) ( F = 277.28, P ＜0. 01 ). IMT in the MS group, Non-MS group and NC group were (1. 10 ± 0. 13 )mm, (0. 82 ± 0. 12 )mm and (0.70 ± 0.11 ) mm, respectively, with significantly difference ( P ＜ 0. 01 ). In addition, the incidence of thickening was 28.99% (20/69), 17.54% ( 10/57 ) and 2.00% ( 1/50 ), respectively, with significantly difference ( P ＜0.01 ). Conclusions Serum level of FFA is associated with IMT in hypertensive patients with metabolic syndrome.

Objective: To summarize our experience on laparoscopic radical prostatectomy via single incision in treatment of early localized prostate cancer. Methods: From June 2009 to August 2009, five patients with localized prostate cancer(T1c) received laparoscopic radical prostatectomy via single incision. A home-made multichannel port was inserted extraperitoneally through a 3 cm incision under the umbilicus. A 10 mm TROCAR and two 5 mm TROCAR were inserted. The prostate was isolated and excised, then the bladder urethral anastomosis was performed. Results The procedures were successful in all the five cases with no transversion to open or standard laparoscopic approach. The mean operating time, the mean operative time for prostate excision, and the mean time for urethrovesical anastomosis were (167±31. 5) min(ranging 135-210 min), (115±26) min (ranging 90-150 min), and (52±5. 7) min(ranging 45-60 min), respectively. The estimated blood loss averaged (90±62) ml (ranging 50-200 ml). Positive margin occurred in one case. Transient incontinence occurred in two cases after the catheter was removed one week later. All patients had a prostate-special antigen level < 0. 2 μg/L during a follow-up of 4-12 weeks. Conclusion: Laparoscopic radical prostatectomy via single incision is feasible and safety. Excellent instruments and skilled surgeon are the keys for the success of the operation.

Objectives To investigate clinic outcome of ticagrelor in treatment of patients with acute ST-segment elevation my ocardial infarction receiving primary percutaneous coronary intervention.Methods Sixty-two consecutive patients with ST segment elevation myocardial infarction (STEMI) receiving primary percutaneous coronary intervention (PCI) were included in this study.The clinic characteristics,thrombolysis in myocardial infarction (TIMI) refuse after PCI,clinical outcomes after 30 d of patients were compared between patients who were treated with ticagrelor (group A 30 cases) and clopidogrel (group B 32 cases).Results There was no difference in the age,proportion of women,hypertension,and diabetics (P ＞ 0.05).TIMI 3 refuse after PCI were significantly higher in group A than group B (96.7％ vs 87.5％,P ＜ 0.05).The 30 d re-angina pectoris was lower in group A than group B (3.3％ vs 12.5％,P ＜0.05).However,tiny bleeding of group A was higher than group B (13.3％ vs 3.1％,P ＜0.05).Conclusions Ticagrelortreatment can improve the prognosis of STEMI receiving primary PCI,but increase the risk of bleeding.

AbstractBACKGROUND: Fas and P53 are important regulator and control gene which can promote apoptosis. They belong to the receptor family part of tumor necrotic factor/nerve growth factor. Their expression products have effects on apoptosis signal transmission, and can regulate and control cell apoptosis in cerebral ischemia-reperfusion injury. And puerarin can alleviate the level of cell apoptosis.OBJECTIVE: To observe the effect of puerarin on Fas and P53, the apoptosis-related gene of nerve cell in hippocampns CA1 region of rats af ter cerebral resuscitation.DESIGN: Randomized controlled trial. SETTING: Department of Emergency, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. MATERIALS: The experiment was carried out at Emergency Department, Tongji Hospital, Tongji Medical College, Huazhong University ofScience and Technology from September 2001 to Februray 2002. Totally 45 of 3 months old Wistar rats of clean grade were selected, and randomly divided into 3 groups: sham operation group, model control group and puerarin treatment group with 15 rats in each group.METHODS: Acute global brain ischemia-reperfusion models were established in rats of puerarin treatment group and model control group. In rats of sham operation group, stigmata of both flanks of the first cervical vertebrae were isolated, but bilateral vertebral arteries were not electric coagulated, and biolateral common carotid arteries were only isolatedwithout clamping close. Rats in puerarin treatment group were given puerarin injection 100 mg/kg, 1 hour before ischemia, and model control group were given normal saline in equivalence while rats in sham operation group were not given medicine. Death of rats in each group was performed separately in the 3rd, 6th, 12th, 24th and 48th hours after cerebral ischemia-reperfusion with 3 rats per group in each time. Hippocampus tissues of rats were isolated, and tissue slices were preparated. And the changes of- the protein expression levels and the number of apoptosis cells of rats in each group at different time point after cerebral ischemia-reperfusion were detected in immuno-histochemical method and end labelling in situ method. MAIN OUTCOME MEASURES: ① The number of positive cells inprotein expression of Fas and P53 in hippocampus CA1 region of rats in each group at different time point after cerebral ischemia-reperfusion was studied. ② Comparison of the number of apoptosis cells in hippocampus CA1 region of rats between groups at different time point after cerebral ischemia-reperfusion were studied, too.RESULTS: All the 45 rats enrolled in research were entered the stage of result analysis: ① The number of positive cells in protein expression of Fas in hippocampus CA1 region of rats in each group at different time point after cerebral ischemia-reperfusion: Obvious gene expression of Fas was not found in sham operation group. In contrast with model control group, obvious decrease was found at all time points after cerebral ischemi a-reperfusion in puerarin treatment group, and in the 6th, 12th, 24th and 48th hour the differences were significant [(15.0±4.3), (13.5±4.9); (40.7±3.4), (27.2±3.1); (37.0±4.8), (22.0±2.1); (24.7±4.1), (18.9±5.3)/mm; P < 0.05,P < 0.01]. ② The number of positive cells in protein expression of P53 in hippocanpus CA1 region of rats in each group at different time point after cerebral ischemia-reperfusion: Obvious gene expression of P53 was not found in sham operation group. In contrast with model control group, obvious decrease was found in the 24th and 48th hour after cerebral ischemiareperfusion in puerarin treatment group [(25.3±4.4), (12.8±2.7); (24.3±3.6), (10.9±3.0)/mm; P < 0.01]. ③ Comparison of the number of apoptosis cells in hippocampus CA1 region of rats between groups at different time point after cerebral ischemia-reperfusion :In contrast with model control group,obvious decrease was found in the 12th, 24th and 48th hour after cerebral is chemia-reperfusion in puerarin treatment group [(34.0±3.7), (21.0±3.7); (41.0±4.2), (33.0±4.8); (71.0±5.5), (41.0±3.4)/mm; P < 0.01].CONCLUSION: In rats which were given puerarin treatment, the expression of Fas decrease obviously in 6 to 48 hours after cerebral ischemiareperfusion, and the expression of P53 decreased obviously in the 24th to 48th hour after cerebral ischemia-reperfusion, and a descent tendency could be found in the number of apoptosis cells. These can further prove the cerebral protective effect of puerarin, and indicate that the inhibition of puerarin to cell apotosis after cerebral resuscitation is related to its effect on the decrease in protein expression of apoptosis-promoting gene, Fas and P53.Puerarin has a protective effect on cerebral ischemia-reperfusion injury of rats. In comparison with model control group, the expression of Fas in puerarin treatment group has an obvious decrease inthe 6th to 48th hour after cerebral ischemia-reperfusion, the expression of P53 has an obvious decrease in the 24th to 48th hour after cerebral ischemia-reperfusion, and the number of apoptosis cells decrease obviously, too, which further improves the cerebral protective effect of puerarin and indicates that the inhibition of puerarin to cell apoptosis after cerebral resuscitation is related to its effect on the decrease in protein expression of apoptosis-promoting gene Fas and P53.

Objective To detect the expressions of nerve growth factor (NGF) and its receptors tyrosine kinase A (TrkA) as well as p75 neurotrophin receptor (p75NTR) in the lesions of lichen planus.Methods Biopsy specimens were collected from the lesions of 32 patients with lichen planus and normal skin of 12 healthy human controls and subjected to paraffin embedding.Immunohistochemical avidin-biotin complex (ABC) method was used to detect the expressions of NGF,TrkA and p75NTR.Results NGF and TrkA,which were located in the cytoplasm of keratinocytes,were strongly or moderately expressed in the lesional skin specimens,but absent or weakly expressed in the normal skin specimens (both P ＜ 0.01).No significant differences were observed in the expression of p75NTR between the lesional and normal skin specimens,or in the expressions of NGF,TrkA or p75NTR among specimens from patients in different age groups,patients of different gender or lesions at different sites (all P ＞ 0.05).There was a positive correlation between the expression of NGF and TrkA in the lesions of lichen planus (R2 =0.535,P ＜ 0.01).Conclusion NGF may play a certain role in the development of lichen planus via its highaffinity receptor TrkA.

Objective To summarize our experience in surgical treatment of cervical intramedullary spinal cord tumors and to identify the prognostic factors associated with postoperative-neurological status. Methods The clinical data of 65 consecutive patients with cervical intramedullary spinal cord tumors undergoing operation between Jan. 2009 and Dec. 2013 were retrospectively reviewed. McCormick Scale was applied to evaluate the preoperative and postoperative neurological functions. Multivariate logistic regression analysis was used to determine the independent prognostic factors of postoperative neurological status. Results Laminectomy was performed in 61 patients and unilateral multilevel interlaminar fenestration (UMIF) was applied in 4 patients. Of all the 65 patients, 48 received total resection, 4 received subtotal resection and 13 received partial resection. The follow-up time was from 4 months to15 years. The median follow-up time was 68 months. The clinical symptoms were relieved in 42 patients after operation, maintained unchanged in 14 and aggravated in 9. The pain remission rate of the patients was the highest (82. 4%), followed by the sphincter dysfunction remission rate (68. 8%), and the sensory disturbance remission rate of the patients was the lowest (39. 6%). Based on McCormick Scale, the postoperative neurological functions was improved in 18 patients (27. 7%) and maintained unchanged in 39 (60%) , while eight patients (12. 3%) developed neurological deterioration. Multivariate logistic regression analysis revealed that good preoperative neurological function (OR=19. 87, 95% CI; 4. 10-96. 23, 7 = 0. 000)and total resection (OR=7. 40, 95% CI; 1. 34-40. 95, 7 = 0. 022) were the independent protective factors for postoperative neurological status. Conclusion Microsurgical resection is the first-line treatment for cervical intramedullary spinal cord tumors , which can achieve a satisfying outcome in most cases. Preoperative neurological status and surgical extent are significantly associated with the postoperative functional outcome of patients.

by lfow cytometry. According to CAG morphology, the plaques included 3 types as Type I, Type II and TypeⅢ. The patients also received coronary CT angiography (CTA), upon CTA value, the plaques were classiifed by soft plaque, ifbrous plaque and calciifed plaque. Expressions of platelet surface EMMPRIN and GPVI among different groups were compared.
Results:①Compared with Control group, ACS and SAP groups had increased expressions of EMMPRIN (5.82 ± 0.81 and 3.45 ± 0.48) vs (1.35 ± 0.15) and GPVI (16.22 ± 5.27 and 8.20 ± 2.87) vs (4.14 ±1.17); the expressions in ACS group were higher than those in SAP group, allP<0.05.②In ACS group, compared with Type I plaque, the patients with Type II and TypeⅢ plaques had elevated levels of EMMPRIN (6.35 ± 1.05 and 4.09 ± 0.67) vs (2.45 ± 0.27) and GPVI (19.50 ± 4.55 and 10.81 ± 2.33) vs (5.89 ± 1.28); the expressions in patients with Type II plaque was higher than those with Type III plaque, allP<0.05.③In ACS group, compared with calciifed plaque, the patients with soft and ifbrous plaques had the higher levels of EMMPRIN (6.18 ± 1.01 and 3.87 ± 0.56) vs (2.43 ± 0.25) and GPVI (19.14 ± 4.27 and 11.08 ± 1.94) vs (5.96 ± 0.99); the expressions in patients with soft plaque was higher than those with ifbrous plaque, allP<0.05.④In CAD patients, EMMPRIN expression was negatively related to plaque type (95% CI: -0.359 to -0.206, β: -0.211) and positively related to clinical type (95% CI: 0.893-1.034, β: 0.893); GPVI expression was negatively related to plaque type (95% CI: -1.222 to -0.586, β: -0.181) and positively related to clinical type (95% CI: 3.576-4.164, β: 0.960).
Conclusion: Expression levels of platelet surface EMMPRIN and GPVI were closely related to the stability of coronary plaque, both of them were the risk factors for severe coronary lesions. EMMPRIN and GPVI may have certain predictive value for early diagnosis of arteriosclerosis in ACS patients.

Objective To evaluate the changes of the waveform of the photopic negative response in flash-electroretinogram, visual acuity and central retinal thickness in the treatment of intravitreal injections of bevacizumub. Design Retrospective self-comparative case series. Partidpants 8 subjects (9 eyes) with exudative age-related macular degeneration and 3 subjects (3eyes) with proliferative diabetic retinopathy. Method Evaluation protocol included examinations of the Early Treatment Diabetic Retinopathy study visual acu-ity, visual field, intraocular pressure, fundus fluorescein angiography, optical coherence tomography and flash-electroretinogram. Intravit-real injections of bevacizumab, 1.25 mg (0.05ml), were given under an operating microscope and aseptic conditions. All the subjects were followed-up one month later. Main outcome Measure The amplitudes of PhNR, visual acuity and central retinal thickness. Re-sult At 1 months, the mean amplitudes of PhNR and mean visual acuity in all cases had no obvious change (n=12, P>0.05).The central retinal thickness reduced obviously (n=12, P<0.05), but it was neither significantly correlated with PhNR (r=0.294, P=0.145) nor with visual acuity(r=-0.358, P=0.073). Conclusion The single intravitreal injection of bevacizumab is showed promising in absorption of in-traretinal edema and subretinal fluid in patients with exudative age-related macular degeneration and proliferative diabetic retinopathy, but the changes of visual function (including PhNR) might need further investigation.
