Objective To explore the clinical characteristics and effects of thrombolytic and anti coagulation treatment in over 70 year old patients with pulmonary thromb embolism(PTE). Methods The clinical findings, diagnostic techniques, effects of thrombolytic therapy and anti coagulation in 58 over 70 year old patients with PTE were analyzed retrospectively. Results Deep venous thrombosis (DVT) in lower limbs (74 1%) was the most common thrombolism prone factors in our study. Limitation of movement and long term stay in bed due to a variety of causes were in the next place. The clinical findings were atypical, associated with a false diagnostic ratio of 46 5% in elderly patients with PTE. Undefined causal and different degree of dyspnea along with sudden and persistent hypoxemia were the main characteristics. Spiral CT and radioactive nuclear ventilation perfusion scan were important methods for diagnosis of PTE with positive finding of 95 7% and 62 5%, respectively. The effective and cure rate of thrombolytic therapy combined with anti coagulation, anti coagulation and anti platelet therapy was 91 3%, 75 8%, 0 and 47 8%, 17 2%, 0, respectively. Conclusions The most common risk factors of PTE in the elderly was DVT and the long term stay in bed or stay without active moving. The clinical symptoms were not only atypical but also variable. Thrombolytic with anti coagulation therapy is safe and effective, but anti platelet coagulation alone is not benefit.

Methods Mice of spontaneous abortion(CBA/J?DBA/2) were divided into two groups: immune group and non-immune group.Trophoblast membrane antigen-2(TMA2)or ovum albumin(OVA) was administered orally to the mice in the immune group.Mice of normal pregnancy(CBA/J?BALB/c) were served as controls.The number of CD80/CD86 M of spleen and mesenteric lymph node(MLN) were determined by double-label FCM method. Results In the MLN,CD80 M of non-immune group was increased significantly as compared with that of the control group(P

Objective 22q11 microdeletion is featured with hemotological dysfunction,among others:hypocalcemia,thrombocytopenia and megathrombocyte.This study was trying to work out the platelet characteristics of 22q1 1 microdeletion patients and its potential clinical application.Methods A total of 80 cases who had undergone open-heart surgery were selected and confirmed with fluorescence in situ hybridization (FISH) to have 22q1 1 microdeletion among 40 cases while the others were negative.The relevant data in full blood routine of all the 80 cases in hospital information system (HIS) then were collected and analyzed with suitable statistical methods.Results The mean platelet volume in microdeletion group was statistically higher than that in the control group [(11.20 ± 1.94)fL vs (8.95 ± 1.58) fL,P ＜0.01].The area under the receiver operating characteristic (ROC) curve was 0.82,meaning significant predictive values.The corresponding sensitivity and specificity for mean platelet volume (MPV) =10 fL were 70.0 ％ and 80.0 ％,respectively.Conclusions MPV in congenital heart defect patients with 22q11 is significantly higher than those without 22q11.It is an effective method for preliminary screening 22q11.Being obtained from full blood routine data,it is economic and quick.MPV =10 fL can be used as a cutoff for guidance for irradiated blood transfusion postoperatively.

BACKGROUND: It is very important to explore an optimal loading force that can both allow effective intrusion and cause no damage to the teeth.OBJECTIVE: To investigate the optimal loading conditions, including loading force values and directions, in the intruding mechanics of maxillary anterior teeth.METHODS: A three-dimensional finite element model (3D FEM) of the maxillary anterior teeth was constructed to include the periodontal ligament (PDL), alveolar bone, and appliance (brackets and wire). The initial stress distribution and force of the maxillary anterior teeth were analyzed when the 3D FEM was loaded with different intruding force values and directions. RESULTS AND CONCLUSION: The optimal value of the intruding force for 6 anterior teeth fell within the range from 0.5 N to 1.0 N. The maximum stress was detected at the distal cervical level of the lateral incisor, and a relatively even distribution of initial stress was observed at 20° palatal deviation to the Y axis. The results suggest that using mini-screw implants at the labial region between the canine and lateral incisor and a combined 0.5-1.0 N intruding force with a distal force could be an optimal intrusion force system by which patients with normal occlusion could obtain a pure intrusion of anterior teeth.

Objective:To explore the effects of compound Danshen dripping pills (CDDP) and CDDP combined with transplantation of human umbilical cord blood cells (HUMNCs) on the inlfammatory response, oxidative stress, myocardial cell apoptosis and cardiac function, and also to investigate the possible mechanisms of the combined therapy in the acute myocardial infarction (AMI).
Methods:Rabbit model of AMI successfully established by ligation of the letf anterior coronary artery (LAD). Forty rabbits were randomly divided into 4 groups (n=10 per group):a control group, injected with 0.5 mL of saline in 24 h atfer AMI and then gavaged with 5 mL of saline daily;a CDDP group, injected with saline 0.5 mL atfer AMI and then gavaged with CDDP (270 mg/d) daily;a transplantation group, injected with 0.5 mL of saline contained 3 × 107 HUCBMCs [labeled with green fluorescent protein (GFP)] and then gavaged with 5 mL of saline daily;a combined group, injected with 0.5 mL of saline contained 3 × 107 HUCBMCs (labeled with GFP) and then gavaged with CDDP (270 mg/d) daily. Cardiac function index such as left ventricular fractional shorting (LVFS) and ejection fraction(LVEF) were measured by echocardiography;the pathological changes were observed by HE staining and the white blood cells in the myocardium were determined by light microscopy. hTe superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in myocardium were detected by nitrotetrazolium blue chloride (NBT) and thiobarbituric acid colorimetric measurement respectively. hTe number of transplanted cells in the myocardium was examined by GFP positive cells counted with lfuorescence microscopy.
Results:1) Compared with the control group (at 1 or 4 week), LVEF and LVFS were signiifcant improved in the CDDP group, the transplantation group and the combined groups (all P<0.05), the improvement degree of cardiac function in the combined group was the most significance. There was no significant difference between the CDDP group and the transplantation group. 2) Compared with the control group (at 1 or 4 week), the number of white blood cell, myocardial cell apoptosis ratio were decreased signiifcantly in the CDDP group, the transplantation group and the combined groups (all P<0.05), this decrease in the combined group was the most signiifcance, and there was no significant difference between the CDDP group and the transplantation group. 3) Compared with control (at 4 week), the SOD activity was increased signiifcantly, and MDA content in myocardium was decreased in the CDDP group, this change in the combined group was the most signiifcance. 4) GFP-positive cells were found to be present in the peri-myocardial infarction area in the transplantation group and the combined group at 1, 4 weeks post-transplantation. hTe number of the GFP positive cells in the combined group was more than that in the transplantation group (P<0.05).
Conclusion:The intravenous transplantation of HUMNCs combined with the CDDP in the treatment of rabbits with AMI could increase the survival rate of transplanted cells and inhibit the myocardial cell apoptosis, therefore improve the heart function. hTe possible mechanism of the combined treatment may be involved in the inhibition of the inlfammatory response and oxidative stress in the myocardium following AMI.
