Objective To investigate the changes of coagulatory functions in patients with fragmental femoral fractures before operation.Methods Twenty adults patients undergoing fragmental femoral fractures, ASA class Ⅰ , hospitalized on the injury day, were selected as test group (group Ⅰ) . Fifteen healthy adults were selected as control (group Ⅱ). The fasting venous blood samples were taken on the morning of 2nd and 6th day after femoral fracture for measurement of the parameters of thromboelastography (TEG) [including R-time, K-time, alpha angle, maximum amplitude (MA) and elastic shear modulus (G)], D-dimer concentration (D-Di), platelet count (PLC) and platelet aggregation rate (PAgR) .Results The values of TEG parameters, D-Di, PLC and PAgR were in normal ranges in group Ⅱ. Compared with those in group Ⅱ, in group Ⅰ the K time was shortened and alpha angle, MA, G, D-Di increased significantly on the 2nd day after femoral fracture(P

Objective:To investigate the dysfunctional attitudes of hypertension patients with depression.Methods: After evaluating 1088 patients with essential hypertension by HAD,patients with HAD positive result were evaluated with HAMD and HAMA.The subjects with positive results(n=262)were compared with the normal group(n=306).They were assessed with the dysfunctional attitudes scales(DAS).Results:①The sequence of dysfunctional attitudes of hypertension patients with depression were cognition philosophy,seeking applause,and compulsion.②Significant gender differences were found in dysfunctional attitudes.③Most of the subscales of DAS were significantly positively correlated with depression symptoms(P

The concentration of glycosylated serum protein (GSP) in 125 normal subjects and 105 diabetic patients was measured. The result showed that the mean value of GSP in diabetic patients increased as compared with that of normal subjects, and the mean , concentration of GSP correlated significantly with that of fasting blood glucose in diabetic patients as well as that the mean value of fasting blood glucose which was determined 1-3 weeks before. The level of GSP may be a sensitive indicator for recent control of diabetes

Objective To retrospectively analyze the importance of preoperative ultrasound and D-dimer determination for patients with traumatic fractures so as to evaluate the value of vascular color Doppler ultrasound in diagnosing of vein thrombosis and the correlation between D-dimer level and lower extremity vein thrombosis. Methods The study involved 1000 in-patients with multiple traumatic fractures, femoral fractures, tibial fractures or tibiofibular fractures admitted from March 2008 to April 2009 who were prepared for open reduction surgery. There were 568 males and 432 females, at age range of 20-90 years ( average 54.8 years). Vein D-dimer was examined in the morning on the second day after admission. Vascular color Doppler ultrasound was performed on the lower extremity one day before operation (after the swelling faded away, about 4-10 days after fracture). Results The vascular color Doppler ultrasound on the lower extremity showed vein thrombosis of the lower extremity in 64 patients (6.4%) including 26 patients with iliac- femoral vein thrombosis, 10 with popliteal-tibial vein thrombosis and 28 with gastrocnemius or soleus muscle vein thrombosis. On the second day after operation, out of 736 patients (73.6%) with D-dimer above normal (324 μg/L), 56 patients (7.6%) developed thrombosis afterwards;of 264 patients (26.4%) with normal D-dimer, eight patients (3.03%) developed thrombsis. Incidence of thrombosis in patients with D-dimer above 650 μg/L was higher than that in patients with D-dimer below 650 μg/L (P＜0. 01). Conclusions Preoperative lower extremity vein Doppler ultrasound in traumatic fracture patients can lower the risk of fatal lung thrombosis caused by existing deep vein thrombosis.D-dimer above normal level indicates tendency of thorombosis. However, normal D-dimer still have the possibility to develop thrombosis, which deserves attention.

OBJECTIVETo explore significance of preoperative color Doppler flow imaging (CDFI) for screening deep vein thrombosis in upper limbs fracture.

METHODSFrom January 2009 to December 2011, 1200 patients with upper limb fracture caused by trauma were respectively analyzed. There were 833 males and 367 females,ranging from 20 to 78 (mean 41.94 +/- 15.41) years. All patients had swelling and pain in injured limbs when enrolled. CDFI was used to examine upper limbs vein at 3 to 10 d after improvement of swelling, 1 day before reduction. Relationship among occurrence of thrombosis, gender, age and fracture sites were analyzed. Patients with DVT were analyzed with respective study to decide whether combined with diabetes, hypertension and hyperlipidemia.

RESULTSAll patients were checked by CDFI,which confirmed 9 cases with DVT. The rate of thrombosis was 0.75%, women than men (P < 0.01). The risk of blood clots occurred over 30 years, and the occurrence of thrombosis in humerus fracture was higher than radius ulnar fracture. One of 9 patients combined with hypertension and hyperlipidemia, 1 case combined with diabetes, and 7 cases with no complication.

CONCLUSIONUpper trauma fracture may occur deep vein thrombosis; CDFI should be used to check DVT in qualified hospital,which can maintain medical safety,decrease occurrence of medical disputes, and ganrantee patient's safety.

Objective To investigate the expression of oncogene survivin,p53 in breast cancer and its ~prognostic significance. Methods The expression of survivin,p53 in breast cancer tissues of 80 cases were detected by immunohistochemistry S-P method, and its correlation with axillary lymph node metastasis and ~5-year disease free survival (DFS) was analysed.Results In breast cancer tissues,survivin gene positive ~expression rate was 68.75%(55/80), p53 gene positive expression rate was 46.25%(37/80), and both had a positive correlation with axillary lymph node metastasis but negative correlation to 5 years DFS(P0.05);survivin and p53 genes expression have positive corrlation(P

OBJECTIVETo observe features of Icariin in promoting osteogenic differentiation of SD rat bone marrow mesenchymal stem cells (BMSCs) in vitro.

METHODS(1) SD rats' BMSCs were isolated and purified by mechanically isolated and cultured by whole bone marrow adherent method. Effects of various concentrations Icariin on serum activities of alkaline phosphatase (ALP) were detected using amino antipyrine phenol determination method at day 3, 6, 9, 12, 15, 18, and 21. Calcium nodes of each groups were detected using alizarin red staining. Roles of various concentrations Icariin in promoting osteogenic differentiation of BMSCs were observed. (2) BMSCs were divided into the blank control group, the osteogenic induced group, and the Icariin group (0.5 microg/mL). ALP activities were detected at day 7, 14, and 21 of culture. Meanwhile, ALP positive staining rate and calcium nodes were detected at day 14 and 21 respectively. Additionally, mRNA expressions of Runt-related transcription factor-2 (Runx2) and Osteocalcin were detected at day 7, 14, and 21 by real-time fluorescent quantitative PCR.

RESULTS(1) 0.05-5.0 microg/mL Icariin could significantly elevate serum ALP activities. Of them, 0.2-2.0 microg/mL Icariin significantly increased calcium nodes numbers (P < 0.01). (2) When Icariin promoted osteogenic differentiation of BMSCs, Runx2 mRNA expression levels and ALP activities increased earlier and then decreased, while osteocalcin mRNA expression levels continued to increase (P < 0.01). Compared with the osteogenic induced group, ALP activities and ALP positive staining rate were both elevated after 14 days of Icariin treatment in the Icariin group (P < 0.05, P < 0.01).

CONCLUSIONSIcariin could promote the differentiation of BMSCs to osteoblasts by up-regulating Runx2 mRNA expression levels. It also could promote the mineralization by increasing ALP secretion and Osteocalcin mRNA expression levels, thereby promoting mature of newly generated osteoblasts.
