Objective To explore the expression of naturally occurring plasma anti-? amyloid (A?) antibody in children and youngsters .Methods According to each 10 years, 28 healthy cases aged from 1~30 years old were diviedd to 3 groups.In the 3 groups,the plasma anti-A? antibody was detacted by immunostained with paraffin sections from Tg2576 mice brain to make a specific tissue amyloid plaque immunoreactivity (TAPIR) and immunoprecipitation analysis. Results The total occurrence rate of anti-A? antibody was 27.8%. There was no significant difference of TAPIR positive rate in each age group. They had the similar immunospecialties to middle-aged and elderly healthy controls. Conclusion Plasma anti-A? antibody can be occured before amyloid deposits and senile plaques in brain.

AIM: To examine whether calcitonin gene-related peptide (CGRP) enhances nitric oxide (NO) level in pulmonary circulation blood and observe the influence of CGRP on mean pulmonary artery pressure (mPAP) in rabbits with acute lung injury (ALI) caused by oleic acid. METHODS: The level of NO was assessed by measuring the presence of nitrite in cervical artery blood by the Griess reaction, mPAP was measured with right ventricular catheter. RESULTS: The level of nitrite in cervical artery blood was significantly increased and the mPAP was markedly reduced after administration of CGRP intravenousely.CONCLUSION: CGRP enhanced the NO level of pulmonary circulation blood and reduces the mPAP significantly in rabbits with ALI.

Objective To investigate the effect of Gangliosides on brain protection after cerebral ischemia reperfusion injury in rats. Methods The middle cerebral artery (MCA) focal cerebral ischemia /reperfusion rat models were used by thread occlusion method. The cerebral infarct volume, neurologic function deficits and neurons apoptosis in cerebral ischemic region were observed following focal cerebral ischemia 90 min (IR 0 h) and ischemia 90 min / reperfusion 24 h (IR 24 h) by injecting Gangliosides and normal saline intraperitoneally, respectively. Results A significant reduction of infarct volume was found in the Gangliosides-treated group compared with the control group. Furthermore, Gangliosides induced significant amelioration of the number of neuron apoptosis and neurologic dysfunction following focal cerebral ischemia and reperfusion in rats (all P

Objective To investigate the clinical value of heart-type fatty acid-binding protein ( H-FABP) and N terminal probrain natriuretic peptide (NT-proBNP) in sepsis patients with myocardium injury. Methods 118 sepsis patients were included as survivor group (68 cases) and death group (50 cases) according to their prognosis outcome. 50 healthy people were selected as control group. Creatase, H-FABP, NT-proBNP, APACHEⅡscore and 28 day morbidity of control group and sepsis patients were assessed at 1 h, 6 h after admission by physical examination . Results At 1 h after admission , APACHEⅡscore , H-FABP and NT-proBNP level in sepsis patients were significantly higher than control group (P < 0.05); APACHEⅡscore, H-FABP, NT-proBNP and cTnI level at 6 h after admission were higher than that at 1 h (P < 0.05); APACHEⅡscore, H-FABP and NT-proBNP level in death group were higher than survivor group at 1, 6 h after admission (P < 0.05), cTnI level at 6 h after admission was higher in death group (P < 0.05). Futhermore, H-FABP, NT-proBNP and cTnI at 6 h after admission were positively correlated with each other (both P < 0.05). At 6 h after admission , H-FABP showed a better predictive value of 28-day mortality than NT-proBNP and APACHEⅡscore (P < 0.05). Conclusion H-FABP and NT-proBNP may suggest important significance in early diagnosis and prognosis prediction of sepsis patients with myocardium injury.

Objective To discuss the application of C-arm CT scanning technology in performing transcatheter arterial chemoembolization for hepatic cancer.Methods Seventy-seven patients of hepatic cancer were treated with selective transcatheter arterial chemoembolization(TACE),which was followed by C-arm CT scanning to observe the embolization effect.C-arm CT scanning was also performed before TACE in 13 cases.Three-dimension reconstruction of the images was carried out on Integris 3D-RA workstation.The therapeutic results were evaluated.Results The embolization state of both the peripheral margin and the body of the tumor could be clearly displayed on CT scans in all 77 patients.Some tiny liver lesions were also detected in 3cases.Conclusion C-arm CT scanning technology is a newly-developed high-tech examination.This examination is very helpful for making the proper operation scheme and for evaluating the curative effect of intravascular intervention.Compared to the traditional CT scanning,C-arm CT scanning can provide more accurate information and stereoscopic image of the lesions,therefore,the whole course of the interventional procedure can be entirely under the operator's control and the curative effect can be evaluated at any time during the operation.C-arm CT scanning can be effectively employed in interventional therapy for multisystemic disorders.

Objective:To investigate the curative effect of different restorations for deciduous teeth defect of children.Methods:67 children with teeth defecting seriously and being unable to fill restore were enrolled from January 2011 to January 2015 and randomly divided into three groups,one group of patients accepted metal crown restoration (Group A,n=22),one group adopted ceramic inlay restoration (Group B,n=22),and the last one accepted silver amalgam filling (Group C,n=23),the curative effect and incidence of adverse reactions among three groups in the period follow-up were compared.Results:In the period of 18-month follow-up,6 patients of toothache,5 patients of food impaction and crevices between restorations and teeth,3 cases of gingival congestion,2 cases of secondary caries were observed in group C;3 cases of toothache,1 case of food impaction,gingival congestion,crevices between restorations and teeth and secondary caries were observed in group B;2 cases of toothache and food impaction,1 case of gingival congestion were observed in group A.The incidence of adverse reactions in group A and group B was lower than those in group C (P＜0.05),which was lower in group A than that in group B,but no significant difference was found between group A and group B (P＞0.05).Conclusion:The restoration of metal crown and ceramic inlay deserved popularization had better curative effect and safety for deciduous teeth defect of children than silver amalgam filling.

Feeding adult male rats with gossypol acetic acid at a dose of 15 nig/kg/day for 50 days led to infertility. Spermatogenesis and sperm motility were impaired ( table 1 ) . However, testosterone, K+ and Na+ concentsrations in serum and RTF were found to be unchanged (table 2, 3 ) . It suggests that at low antifertility doses gossypol disrupts spermatogenesis in the seminiferous epithelium without affecting testosterone, K+ and Na+ secretion and translation in testis.

BACKGROUND:Hereditary factor occupies a certain position in suicidal behavior of depression. The researches in the past are focused on the hereditary effect on bipolar depression suicide.How do hereditary patterns and effects work in suicidal behavior in unipolar depression?OBJECTIVE: To probe into hereditary patterns and effects on suicidal behavior in unipolar depression.DESIGN:Retrospective investigation.SETTING:A municipal psychiatric hygienic centerPARTICIPANTS:Unipolar depression group included 115 outpatients and inpatients diagnosed in Wuxi Psychiatric Hygienic Center from June 1st 1983 to May 31st 2002.The diagnosis tallied with Standards on Depression Onset in Categories and Diagnostic Standards on Psychiatric Disturbance in China of 3rd Edition and with Standards on Severe Depression Onset in Manual of Diagnosis and Statistics of Psychiatric Disturbance in America of 4th Edition.The attack frequency of all the cases ≥ 3 times or the cases had been relieved ≥8 years after a couple of attacks.METHODS:The patients who tallied with the standards on unipolar depression received the investigation in every family tree under the instruction of 2 physicians-in-charge and more than 2 physicians and filled up the self-made investigation form of psychiatric family tree,including mainly the data of social demography of patients and their first grade relatives,characters of disease onset,frequency of attack,history of treatment and suicide. After re-diagnosed by 2 physicians-incharge and more than 2 physicians and checked by one physician-incharge,the cases were collected in patient group. The interview was carried on for the patients with suicidal behavior among all of the survived patients (107 cases) and first grade relatives (14 cases).The interview (337 cases) and investigation with letter (380 cases) were carried on for the first grade relatives without suicidal behavior. The investigation forms of 13 dead cases (8 cases of patients, 5 cases of first-grade relatives) were provided and filled-up by one or two first grade relatives. Two researchers interviewed the cases in the control,inquired the first grade relatives and filled up the investigation form of family tree.Single factor analysis was used for all the data and Falconer pattern of polygenetic threshold-value theory was used to estimate hereditary rate and standard error in suicidal behavior.Separation analysis in medical hereditary mathematic method and polygenetic threshold-value theory were applied to discuss the hereditary patterns.MAIN OUTCOME MEASURES:Hereditary effects and patterns of suicidal behavior in unipolar depressed patients.RESULTS:Suicidal risk of unipolar depressed patients(51.30%,59/115)was higher than their first grade relatives (2.58%,19/736) (x2=283.16,P ＜ 0.01).Suicidal risk of the first grade relatives (2.58%,19/736) of unipolar depressed patients was higher than the control (0.12%,3/2469)(x2=50.36,P ＜ 0.01).Suicidal risk of the first grade relatives of the patients with suicidal behavior (3.8%,14/372) was higher than that of the first grade relatives of the patients without suicidal behavior (1.4%,5/363)(x2=4.14,P＜ 0.05).The weighted average hereditary rate and standard error was (70.16±0.79)% for suicidal behavior in unipolar depression.The predictive morbidity of suicidal behavior in the first grade relatives was 3.1% and the real morbidity was 2.6%,which did not indicate significant difference (u =0.766, P ＞ 0.05).CONCLUSION:Suicidal behavior of unipolar depression presents obvious hereditary effects and its hereditary patterns tally with polygenetic inheritance.

Purpose To investigate the clinicopathlogical characteristics, diagnosis and differential diagnosis of ovarian small cell car-cinoma hypercalcemic type ( OSCCHT) associated with acute renal dysfunction. Methods A case of OSCCHT associated with acute renal dysfunction was reported. The clinical and pathologic data, treatment and pathological examinations were analyzed and the related literatures were reviewed. Results A 29-year-olds women was presented to hospital with inappetence and significant weight loss for 2 months. The laboratory examination showed abnormal renal function, and pelvic cavity mass, possibly coming from adnexa of the uterus was seen by radiography. Serum levels showed significantly increased serum calcium with acute renal dysfunction. An emergency opera-tion was performed just after renal function partially recovered by 2 times hemodialysis. During surgery, right ovary tumor with a size of 12 cm × 10 cm × 10 cm was inspected. Microscopically, the tumor cells were arranged in a diffuse solid pattern, mutiple nodules were separated by fibrous tissue. some small folliculars and pseudoglandular cavities with acidophilia secretion within nodules could been ob-served. Tumor cells were medium to large with eosinophilic cytoplasm, round or oval vesicular nucleus, increased karyoplasmic ratio and pathologic mitosis. Immunohistochemistry revealed that the tumor cells expressed EMA, CKpan, C-erbB-2 ( +) , CA125 ( focal+) and Ki-67 proliferation index was about 60%, while ER, PR, Syn, CgA, PTH, Inhibin, CD99, AFP, PLAP, CD30 and CD20 were not expressed. Conclusion Ovarian small cell carcinoma hypercalcemic type with acute renal dysfunction is a very rare with a rapidly progressive and highly malignant tumor. The final diagnosis mainly lies on clinical information ( hypercalcaemia) , morphology and immunohistochemistry, combined with electron microscopy and molecular biological detection when necessary.

Objective To study the significance and value of imaging typing by analyzing the correlation between contrast-enhanced ultrasound perfusion imaging typing and vascularization in patients with primary hepatocellular cancer.Methods The early enhanced arterial phase reflecting angioarchitecture,and the size and edge of enhanced tumor closely related to microvessel distribution, position and density, were observed and analyzed in 89 patients (113 lesions).All the cases were pathologically proved, and some received immunohistochemisty staining and the microvessel density were recorded.Results The perfusion imagings were classified into 4 types according to changes on contrast-enhanced ultrasound,dendritic,mixed,circular and net-like type.Atypia vessels were commonly seen in dendritic type,and Ⅲ and Ⅳ accounted for 79.1%.The microvessel density was higher than the other types.The circular type was relatively regular and Ⅲ and Ⅳ accounted for 12.5%.The microvessel density was lower than the other types.Combined with the contrast-enhanced ultrasound perfusion imaging and compared with pathological grading,growing methods and microvessel density, the dendritic type was characterized by infiltrative growth, and had strong invasion tendency.The circular type was characterized by expansive growth.And the other two types were characterized by transitional type.Conclusions Contrast-enhanced ultrasound can reflect the angioarchiteeture, the microvessel density and the position,and it is related to the pathological grading and growing methods.
