BACKGROUND:Deep venous thrombosis is one of the common and fatal complications of total joint arthroplasty.For our clinical practice,we require duplex ultrasound and venography to evaluate the presence of deep venous thrombosis,but the diagnostic tools have several disadvantages.OBJECTIVE:To explore the appropriate and non-invasive biomarkers in the early diagnosis of deep venous thrombosis.METHODS:With the key words of Thrombosis,DVT,Biomarker,Total Joint Arthroplasty,D-dimer,Factor VIII,Thrombin Generation,Fibrin Monomer,P-selectin,Inflammatory Cytokines,Microparticles,Leukocyte Count,Genetic factors,MicroRNAs,a computer-based search was performed for articles published in PubMed database from January 1995 to March 2015.After the initial screening,the reserved articles were further detailed,summarized and concluded.RESULTS AND CONCLUSION: Totaly 66 articles were colected.This brief review is used to analyze the mechanism of the biomarkers which are classified into three levels as folow: detection of blood coagulation,inflammation markers and molecular biology and genetics-based biomarkers.The review also showed a great need of economic and safer biomarkers for the clinic and provided the theoretical basis to diagnose and predict deep venous thrombosis in an early stage.

Objective To application of solution focused approach in the functional gastrointestinal disorders.Methods 64 hospitalized clients with functional gastrointestinal disorders were randomly divided into the observation group and the control group with 32 cases in each group.We applied the normal nursing intervention to the control group,while applied the solution focused approach to the observation group.The anxiety and depression score,score of coping way and gastrointestinal symptoms were evaluated using t test.Results The scores of anxiety and depression,coping way and gastrointestinal symptoms were better in the observation group than those in the control group.Conclusions Adoption of solution focused approach can relieve FGID sufferers'negative emotion,such as anxiety and depression,increase sufferers' coping capacity and symptoms,which demonstrate pivotal significance for rehabilitation of functional gastrointestinal disorders.

Objective To investigate the efficacy of warfarin combined with urokinase in the prevention of deep venous thrombosis after hip replacement. Methods 58 patients undergoing hip replacement in our hospital from October 2014 to October 2016 were randomly divided into the observation group and the control group, 29 cases in each group. The control group were treated with oral warfarin, the observation group was treated with warfarin combined with urokinase, two groups of patients were treated for 14d, the incidence of lower limb deep vein thrombosis, follow-up statistics of two groups of patients within three months after operation, the diameter and blood rheology changes before and after weeks of treatment of lower extremity. Results During the treatment and follow-up of 14d patients in the control group, the incidence of deep venous thrombosis was 20.67% significantly higher than the observation group 3.45% (P<0.05); after treatment, the two groups of patients with lower limb circumference difference was significantly reduced (P<0.05), and the patients in the observation group the thigh circumference, calf circumference difference was significantly less than the control group (P<0.05); after treatment, the two groups of patients with high blood viscosity, low blood viscosity, plasma viscosity and hematocrit were significantly lower than those before treatment (P<0.05), and the indicators of the observation group were significantly lower than the control group (P<0.05). Conclusion Warfarin combined with urokinase can effectively prevent the formation of deep vein thrombosis of lower extremity after hip replacement, improve the hypercoagulability of patients and reduce the circumference of the lower extremity, so it is worthy of clinical application.

Objective: To investigate the effect of prenatal tobacco and alcohol exposure on stature and neural development of offspring. Methods: Female mice were exposed to tobacco smoke and alcohol drink from D6 of pregnancy to parturition. The early physical development, neurobehavioral and antioxidative functions were measured in offspring mice. Results: Compared with control, offspring subjected to prenatal exposure showed significant reduced body and organ weights as well as reduced gestational body weight gain. It also resulted in remarkable prolonged neonatal reflexes and reduced motive, coordinative and locomotor activities. Step-down and Y-maze tests revealed marked destroyed memory and learning ability. Futhermore, MDA in offspring brain cytosol and mitochondria increased significantly and the activities of SOD, GSH-Px, CAT and GST were decreased. Conclusion: Prenatal tobacco and alcohol exposures interfere with the early physical and neural development in mice, probably related to decreased antioxidative functions.

Objective:To investigate the characters of ERP in undergraduates with different trait anxiety during exam stress. Methods: By the State Trait Anxiety Inventory, one group of 15 undergraduates with high trait anxiety and another group with low trait anxiety were chosen from 200 participants in Band 4 College English Test. Their change of P3 were observed through NeuroScan 32 Channel ERP System during pre- exam and post- exam. Results: The amplitude of P3 of the group with low trait anxiety was enhanced while another group with high trait anxiety had no significant difference after exam; The latency of P3 of the group with low trait anxiety were decreased while another group with high trait anxiety had no significant difference after exam; There weren’t significant differences in amplitude and latency of P3 between high trait anxiety group and low trait anxiety group before exam; There were significant enhance of amplitude of P3 and decrease of latency of P3 in low trait anxiety group after exam as compared with high trait anxiety group. Conclusion: The result suggests different trait anxiety groups have different cognitive functions. When confronting with the same stress.

AIM: To report a case of wet age-related macular degeneration (AMD) treat with multiple transpupillary themotherapy (TTT) and choroidal neovascularization (CNV) disappeared but retinal pigment epithelial(PRE) and choroidal atrophy occurred with a low vision at the end point.METHODS: Clinical data including fundus hotographs, fundus fluorescein angiography (FFA), indocyanine angiography (ICGA) and optical coherence tomography(OCT) was reviewed.RESULTS: A 72-year-old man complained about blurred vision of his left eye and FFA revealed polypoidal choroidal vasculopathy (PCV) in the macula. His left eye had stable vision of 0.1 for 6 years without any treatment of CNV. About 2 years later, his right eye presented a piece of CNV. During the period of 3 years, the lesion remained more (3×5 PD) and less (1×2PD) in size with remarkable exudates and bleeding, and 7 sessions of TTT were applied with 80-280mW, 2mm of spot, and 60 seconds exposure and with the interval of 3 months or more. The CNV lesion finally disappeared, but there left a white area in the macula and vision decreased from 0.3 to 0.04.CONCLUSION: Although CNV lesion can be eliminated by TTT, obvious atrophy of RPE cells and the choroids can happen and this may not be of help for patient vision. It suggests that the parameters of TTT will be lower than 120 mW/mm and limited less two sessions if applicable, especially for Asia people.

Objective To assess the clinical value of CT in the identification of the etiology of primary aldosteronism(PA).Methods Seventeen cases who underwent both adrenal vein sampling (AVS)and CT examination were retrospectively investigated.By using results of AVS as gold standard.we evaluated CT in the determination of the etiology of(PA).Results Seven cases showed no abnormalities on CT,and six eases exhibited unilateral or bilateral nodules.Enlarged configuration was found bilaterally in 2 cases and unilaterally in one case.and in another case with contralateral nodules.In 15 cases with bilateral adrenal hyperplasia(BAH)pwved by AVS,7 eases had normal CT ima6ng,5 cases showed CT findings consistent with AVS,and 3 cases showed intermediate findings.Conclusion CT imaging is unreliable in the identification of the etiology of PA,especially in the diagnosis of BAH.
