Objective To investigate expressions of vascular endothelial growth factor (VEGF) and nm23 proteins and microvessel density in HCC,simultaneously,their relation with metastasis was also studied.Methods The expression of VEGF and nm23 and CD34 protein in 56 HCCs were detected by immunohistochemical technique.Results Of 56 HCCs, the intensity of VEGF expression in HCCs with metastasis was significantly higher than that in HCCs without metastasis (P

The principle on the pitting electrochemical noise detected by using wavelet transform was described briefly and the signal of pitting electrochemical noise was analyzed for commercial pure aluminum in 3.5 % NaCl solution. The result showed that wavelet transform could not only obtain the waveform characteristic of pitting signaland system noise in the multi-scale space, but also detect the waveform of pitting electrochemical noise according to the transmitting characteristic of the maximum module of wavelet coefficients, which represented the waveform characteristic.

Objective To explore the application of ABCD3 score on stratifying the antithrombotic treatment strategy in patients with capsular warning syndrome (CWS).Methods The clinical features of 15 patients with CWS were analyzed retrospectively,and the risk of stroke were evaluated by ABCD3 score and to guide the treatment of Stratifying antithrombotic therapy.The status of patients hospitalized,discharged and discharged after 90 d were evaluated.Results The frequency of patients with CWS accounted for 2.51％ (15/ 597) of all patients with transient ischemic attack(TIA),and the mean age in patients with CWS was (70.27 ±8.29) years old.The duration of the first onset was (10-30) min,the mean time was (17.33±1.53) min,and ABCD2 score was 5.0-9.0 points,mean score was 7.00±0.26 points,and the total episodes of CWS were 51 times during 24 hours,the mean duration was (18.13 ± 15.36) minutes ((3.0-60.0) min).All 15 cases presented with limb hemiparesis.Of them,9 cases had dysarthria,5 case with ipsilateral facial palsy.All 15 cases CWS patients showed no signs of cortical deficit.The mean NIHSS score at onset was 1.0-6.0 points,mean scores was 3.20±0.31 points.Fourtheen patients were treated with clopidogrel plus aspirin,and 2 cases with administration of the loading dose 300 mg of clopidogrel,1 case was treated with clopidogrel plus aspirin orally followed by intravenous rt-PA thrombolysis.The average hospital periods of all 15 patients was (7.67±0.29) days.The NIHSS score were 0 point at discharge.There was no symptomatic intracranial hemorrhage or death within 90 days follow-up periods.Conclusion CWS is prone to develop a completed stroke.Stratified antithrombotic therapy guiding by ABCD3 score may decrease the risk of ischemic stroke.

Objective To explore the relationship of a polymorphism c.757T ＞ C in C-reactive protein gene (CRP) and carotid artery atherosclerosis in patients with ischemic cerebrovascular disease (ICVD).Methods A case-control study investigated 276 ICVD patients and 125 controls matched for age and sex.Genotypes of-757T/C in CRP were analyzed in patients with ICVD using polymerase chain reaction-restriction fragment length polymorphism.The level of serum C-reactive protein was detected by using immune scatter turbidimetry and the intima-media thickness of common carotid artery and internal carotid artery were measured by color Doppler ultrasonography.The relationship between the polymorphism -757T/C in CRP and carotid atherosclerosis was assessed.Results The genotypes of the polymorphism -757T/Cin CRP in the ICVD group (207/276(75.0％),65/276(23.6％),4/276(1.4％)) was significantly different from the control group (75/125 (60.0％),46/125 (36.8％),4/125 (3.2％) ; x2 =9.531,P =0.008),the frequence of T allele in patients with ICVD (479/552(86.8％)) was increased significantly compared to the control group (196/250 (78.4％)),the frequence of C allele in the ICVD group (73/552(13.2％)) was decreased significantly in contrast to the control group (54/250 (21.6％) ;x2 =9.056,P =0.004).Among the patients with ICVD,the level of serum C-reactive protein in patients with-757TC/CC genotype was elevated significantly than that with-757TC/CC ((4.2± 1.6) mg/L vs (2.7 ± 1.9) mg/L; t =5.900,P ＜ 0.01).Logistic regression analysis demonstrated that the-757C allele in CRP was related to the carotid artery atherosclerosis (OR =1.379,95％ CI 0.852-0.864,P =0.023).Conclusions The polymorphism-757T/C in CRP maybe related to the risk of developing ICVD.The frequency of the-757C allele can increase the level of serum C-reactive protein.And this polymorphism may be associated with carotid artery atheroselerosis in patients with ICVD.

Serum p-amyloid peptide(Aβ)40 and Ap42 levels in patients with type 2 diabetes mellitus (T2DM)and atherosclerosis(AS)were detected by ELISA.The results showed that serum Ap40 level in T2DM group was significantly higher than that in the control group[(274.70±159.51 vs 162.63±87.58)pg/ml,P<0.05],especially in the diabetic patients accompanied with AS[(616.95±195.13)pg/m],P<0.01].Serum Ap40 level in simple AS group was also higher than that in control group[(318.52± 188.65)pg/ml,P<0.05].These results suggest that Ap40 is a risk factor of T2DM complicated with AS.However,there was no difference in serum Ap42 levels among various groups.

Background Choroidal hemangioma is a common benign intraocular tumor.Typical choroidal hemangioma is comparably easy to diagnose,but untypical one might be misdiagnosed as malignant tumor.Contrastenhanced ultrasound (CEUS) has been used to diagnose multiple neoplasm for the past few years.However,the application of CEUSin ophthalmology is less.Objective This study was to investigate the CEUS characteristics of choroidal hemangioma.Methods Fifty-eight eyes of 58 patients who were diagnosed as choroidal hemangioma were included in Beijing Tongren Hospital during July 2010 to December 2012.CEUS was performed on the patients to check the manifestations of choroidal hemangioma.A time-intensity analysis was employed to quantitatively analyzed and compared the maximum intensity (MI),rising time (RT),time to peak (TTP),and mean transit time (mTT) between the choroidal hemangioma and normal orbital tissue and the parameters were contrasted using Wilcoxon signed-rank test.Results CEUS showed that choroidal hemangioma was gradually enhanced by the contrast after intravenous injection of sulphur hexafluoride microbubbles with a high-reference signal in choroidal hemangioma,and the fading procedure was slower in choroidal hemangioma than that of normal orbital tissue.MI,RT,TTP,and mTT were294.20％ (217.35％,373.25％),21.30 (17.35,23.35) s,25.00 (21.68,27.48) s and 59.30 (51.08,78.35) s in the choroidal hemangioma,which were significantly higher than 100.00％ (100.00％,100.00％),17.75 (15.00,20.30) s,22.40 (18.35,24.63) s and 47.25 (40.90,57.23) s in the normal orbital tissue (Z =-6.608,-4.998,-4.650,-4.332,all at P＜0.001).Conclusions Choroidal hemangioma has its own CEUS manifestation characteristics.CEUS is helpful to the differential diagnosis of choroidal hemangioma.

Objective To investigate the requirement and the attitude of the mental health knowledge and some psychological factors indifferent developed regions. Methods The mental patients, their caregivers and normal people in total of 534 were surveyed with the Zung'sSelf-rating Depression Scale, the Questionnaire of Experience and Attitude of the Psychosis (self-edited), the Questionnaire of Requirementand Attitude on Mental Health Knowledge (self-edited), the Social Support Rating Scale and the Simplified Coping Style Questionnaire. Theresults were compared between the developed and the developing regions. Results Compared with those from developing, the requirementwas more and the attitude was more positive on mental health knowledge in all the people from the developed regions; the patients obtainedand applied more support, and took more positive coping style, less depressive emotion; the caregivers took more positive and negative copingstyles, and more depressive emotion; the healthy people applied more support, and took more positive coping style; the caregivers feltmore un-safety and wished the patients stay in hospital longer. Conclusion Development of the region plays a role in the mental health. Thecaregivers need more support and care.

ObjectiveTo investigate the negative emoion and the relative factors in the caregivers of the schizophrenia patients in community. Methods212 caregivers from 12 communities psychotic service stations in 12 prefectures in Guangdong were investigated with the Zung Self-rate of Depression, the experience and attitude of the psychosis, the requirement and attitude on mental health knowledge, the social support scale, the family burden scale and the simply coping style questionaire. ResultsThere were 112 caregivers with no depression (52.8%), 57 with mild depression (26.9%), 30 with middle depression (14.2%), 13 with severe depression (6.1%). More than 50% caregivers worry about unsafty, getting into trouble, worse reputation, genetics, felt scare, strained relationship with the patients. There were significant differences in the hopelessness, the strained relaionship, treatment in other cities, superstition, hospitalization longer between the depression and no depression group, as well as in the economy burden, the interference in the family living, the amusement of family, the family relaionship, the body health and the mental health of the other family members, but no significant in the factors of the requirement and attitude on mental healh knowledge. The caregivers with depression reported less social support than the caregivers with no depression, but there was no difference between these groups in utilization of support. ConclusionThe caregivers of the schizophrenia patients experience negative emotion in community, who need mental and material assistance and the education of the knowledge about diseases.

ObjectiveTo analyse the requirement and attitude to mental health knowledge and the influence factors among the psychosis patients, the caregivers and the healthy pepople.MethodsThe questionnaire survey conducted among the psychosis patients, the caregivers and the healthy pepople from 12 communities which served as the stations for the psychosis where 12 prefectures were organized uniformly by Guangdong Provincial Federation of Disabled Persons.Results1080 sheets of questionnaire were provided, and 986 replied to meet the requirements. The caregivers showed significant difference in requirment and attitude to mental health knowledge compared to the psychosis patients and the healthy pepople(P＜0.05-0.001). The main influence factors were cultural education, regional economic, the frequency of inpatient, the anxiety emotion of the caregivers, which were statistical significance(P＜0.05-0.001).ConclusionIt is lack in the requirement and cognition to mental health knowledge among the psychosis patients, the caregivers and the healthy pepople. Cultural education and economic development are the effective measures to improve the level of the mental health knowledge.

Objective To analyze the family burden of the caregivers of the psychosis patients in community, and the psychosocial factors which influence the family burden.Methods Conducted some questionnaires to survey the requirement and attitude on mental health knowledge,social support,family burden and coping style of the caregivers of the psychosis patients from the twelve communities which served as the stations for the psychosis of the twelve prefectures organized uniformly by Guangdong provincial disabled federation.Results 360 questionnaire was provided,and 308 replied to our questionnaire effectively.The mean score of each single item of the family burden questionnaire was beyond the moderate.The factor score of the economy burden was the highest among the factots of the economy burden(2.33±0.52),the daily activity of the family(2.17±0.53),the recreation activity of the family(2.00±0.58),the family relationship(2.10±0.54),the body health of the family members (2.03±0.65),and the mental health of the family members(2.09±0.68).The bad emotion and experience with the patients aggravated some factors of the family burden(P<0.05～0.01).According to correlation analysis and regression analysis,there were significant relation and impact between family burden with the requirement and attitude on mental health knowledge,subject support,coping style,age,economy,culture and so on(P<0.05～0.01). Conclusion Negative assumption to mental health will aggravate the family burden,transfering the positive message and changing passive coping style will help to reduce the family burden.
