Multiple risk factors lead to occurrence of cardiovascular diseases in common.Besides confirmed tradition-al risk factors,such as diabetes mellitus,dyslipidemia,smoking and hypertension etc.,some new risk factors have been found in recent years.The confirmed risk factors need further research,while the new risk factors need en-hanced study.

Objective:To explore the application of fetal multi-organ hemodynamics in the detection and evaluation of oxygen supply and blood supply for fetus in the third trimester of pregnancy. Methods: 42 pregnant women with gestational diabetes mellitus and 42 healthy pregnant women were divided into observation group and control group, respectively. All of the fetuses of pregnant women received Doppler ultrasound examination, and the pulsatility index(PI), resistance index(RI) and systolic/diastolic(S/D) ratio of umbilical artery (UA)and middle cerebral artery (MCA) of every fetus in the two groups were observed. Besides, the number of fetal distress was recorded and the relationship between fetal distress rate and gestational diabetes mellitus were calculated.Results:The PI, RI and S/D of MCA of fetuses of pregnant women with gestational diabetes mellitus was significantly higher than that of healthy pregnant women (t=7.52,t=6.04, t=8.69,P<0.05). And the PI, RI and S/D of UA of fetuses of pregnant women with gestational diabetes mellitus also was significantly higher than that of health pregnant women (t=11.95,t=9.78,t=8.95, P<0.05). Besides, the fetal distress rate of observation group was significantly higher than that of control group (x2=19.56,P<0.05).Conclusion: The fetal blood flow information which obtained from Doppler ultrasound has very importantly value in the diagnosis of gestational diabetes mellitus, and it verifies the relationship between fetal distress rate and gestational diabetes mellitus. It provides beneficial basis for the prevention and treatment of the gestational diabetes mellitus in the clinical practice.

The ability to feed on vertebrate blood has evolved many times in various arthropod clades. Consequently, saliva of blood-feeding arthropods has proven to be a rich source of antihemostatic molecules. A variety of platelet aggregation inhibitors antagonize platelet responses to wound-generated signals, including ADP, thrombin, and collagen. Anticoagulants disrupt elements of both the intrinsic and extrinsic pathways. Vasodilators include nitrophorins (nitric oxide storage and transport heme proteins), a variety of peptides that mimic endogenous vasodilatory neuropeptides, and proteins that catabolize or sequester endogenous vasoconstrictors. Multiple salivary proteins may be directed against each component of hemostasis, resulting in both redundancy and in some cases cooperative interactions between antihemostatic proteins. The complexity and redundancy of saliva ensures an efficient blood meal for the arthropod, but it also provides a diverse array of novel antihemostatic molecules for the pharmacologist.

Considering the fact that the critical medical education was relatively backward, and the basic medical education was out of touch with clinical practice, this study, combined with the complexity, uncertainty and comprehensiveness of critical care medicine , puts forward the concept of critical care medicine holistic medicine in clinical practice. We try a patient-oriented approach in clinical practice, focusing on the whole, focusing on the interaction relationship among patient and disease and its pathologi-cal and physiology processes, development, complication and prognosis of disease, instead of paying atten-tion only to disease or single organ itself. The purpose of patient-based learning is trying to train medical students and junior residents to form good clinical thinking ability and decision-making ability.

Conclusion: The rehabilitation education plays an important role in the rehabilitation of t he aged cardiovascular patients,and it is very practical and feasible.

Objective To analyze the actions of transforming growth factor ? 1 (TGF-? 1) and tumor necrosis factor ?(TNF-?) in the liver fibrosis formation in chronic viral hepatitis patients and liver cirrhosis patients.Methods Serum levels of TGF-? 1 and TNF-? were measured by ELISA in 107 patients with chronic liver diseases,liver biopsy was performed in 23 patients in order to identify pathological stages under optic microscope.Results The serum levels of TGF-? 1(?g/L) in mild,middle and severe groups of chronic viral hepatitis and liver cirrhosis group were 14 2?5 9,20 1?7 0,30 2?6 7 and 32 6?7 5 respectively.The serum levels of TNF-? (pg/L) were 6 1?3 2,29 8?18 6,57 3?22 5 and 96 7?38 2 respectively.The serum levels of above two markers increased with hepatitis progression.The results of liver biopsy revealed that the changes in these two markers were related to liver cirrhosis degree.Conclusions TGF-? 1 and TNF-? are related to liver cirrhosis formation.

With advances in arthroscopic surgery, arthroscopic repair for rotator cuff tears is often used by surgeons. Surgi?cal methods have already developed from simple single?row fixation and double?row fixation to complicated suture?bridge fixation. Although arthroscopic suture?bridge rotator cuff repair has been proposed to be advantageous over single?row and double?row fixa?tion in biomechanical constructs, the failure of rotator cuff repair is still higher. Different suture methods of medical row anchor in arthroscopic suture?bridge technique may change the suture?tendon loading and decrease the retear of suture?tendon. And differ?ent fixation methods of lateral row anchor in arthroscopic suture?bridge technique may decrease the anchor pull?out. These will be useful to decrease the failure of arthroscopic suture?bridge technique. There will be a good outcome if optical suture and fixation approach can be chosen according to the quality and retraction of rotator cuff, suture tension and the bone quality of the greater tu?berosity in arthroscopic suture?bridge technique.

Crohn's disease is a relapsing systemic inflammatory disease mainly affecting the gastrointestinal tract.Recently,the incidence and prevalence of Crohn's disease is increasing dramatically in Asia,and colorectal cancer is one of the most fatal complications of Crohn's disease.A thorough understanding of the carcinogenesis of Crohn' s disease and enhance the surveillance of colorectal cancer among Crohn's disease is therefore of significant importance to reduce the mortality.In this review,the tendency and molecular mechanism of carcinogenesis of Crohn's disease were discussed,and the present research on the prevention against colorectal cancer in patients with Crohn's disease was introduced.

ObjectiveTo explore the application value of high freuency two-dimensional and color Doppler ultrasonography in the detection of lower limb deep venous thrombosis.MethodsEighty-nine patients with suspicious lower limb deep venous thrombosis were enrolled and received high frequency two-dimensional and color Doppler ultrasonography examination.Vessel diameter,thrombus position,size and echo and blood flow in vessel were observed.ResultsIn 89 patients,42 cases (47.2％) had femoral-iliac vein thrombus;27 cases(30.3％ ) had vein thrombus in intramuscular of cnemis; 13 cases (14.6％) had deep venous thrombosis of the whole lower limbs; 5 cases (5.6％) had intramuscular haematoma;2 cases (2.2％)had subcutaneous soft tissue edema of cnemis.Eighty-four cases were detected having vein thrombus,2 cases (2.4％) were in both lower limbs; 57 cases (67.9％) were in single left lower limb and 25 cases(29.8％)were in single right lower limb.The ratio between thrombus in single left lower limb and in single right lower limb was 2.28:1.The diameter of popliteal vein and femoral vein in affected side limb was respectively (8.8±1.2) mm and (12.9±2.7) mm,which was significantly larger than those in normal side limb[ (5.9 ±1.5) mm and (9.2±2.1 ) mm](P＜ 0.05).ConclusionHigh frequency two-dimensional and color Doppler ultrasonography has high precision in the diagnosis of lower limb deep venous thrombosis and with certain sensibility and specificity.
