Objective To investigate the correlation between plasma homoeysteine (HCY) level and coronary-heart disease (CHD). Methods 117 patients with coronary heart disease (CHD group) and 50 healthy controls (control group) were involved in the investigation. Plasma total HCY level was measured with enzymatic cycling assay. According to the clinical types, CHD cases were divide dinto stable angina pectoris (SAP) group (n = 35), unstable angina pectoris (UAP) group (n = 39) and acute myocardial infarction (AMI) group (n=43). Based on coronary angiography, the CHD cases were further divided into single-vessel (n = 31 ), double-vessel (n = 40) and triple-vessel (n = 46) groups. Results 1 ) Plasma HCY level was significantly higher in CHD group than that in control group (P<0. 01). 2) Plasma HCY level was associated with clinical types, higherst in AMI group, followed by that of UAP group, SAP group, healthy control group. There was statistical difference of HCY level between SAP group and UAP group, SAP group and AMI group, UAP group and AMI group (P<0. 01). 3) Plasma HCY level was gradually elevated in single-vessel, double-vessel and tri- ple-vessel group. There was statistical difference of HCY level between single-vessel group or double- vessel group and triple-vessel group (P<0.01). There was significant difference between single-vessel group and double-vessel group (P>0.05). Conclusion Plasma HCY level is elevated in patients with CHD, and elevated HCY is associated with increased number of stenotic coronary arteries. As a risk factor for CHD, HCY is closely associated with the occurrence and development of CHD.

Objective To evaluate the expression of human kallikrein10 (KLK10) in different endometrioid tissues and analyse the relationship of KLK10 with ER and PR in endometrioid adenoearcinoma.Methods The expression of KLK10 protein in 12 normal endometria,19 endometrial hyperplasia and 34 endometrial carcinoma were detected by immunohistochemistry.The correlations of the expression of KLK10 protein,ER and PR were analyzed.Results The expression of KLK10 in stage Ⅰ,Ⅱ and Ⅲ were 64.3 ％(9/14),30.0 ％ (3/10),10.0 ％ (1/10),and the difference was statistically significant (P ＜ 0.05).The expression of KLK10 in endometrial carcinoma,normal endometria,endometrial hyperplasia were 66.7 ％ (8/12),33.3 ％(4/12),10.0 ％ (1/10),and the difference was statistically significant (P ＜ 0.05).The expression of KLK10 in G1,G2,G3 were 66.7 ％,33.3 ％,10.0 ％,and the difference was statistically significant (P ＜ 0.05).The positive rate of KLK10 expression was 38.2 ％ and the positive rates of ER and PR expression were 67.6 ％and 55.9 ％,respectively,in 34 endometrial carcinoma.The expression of KLK10 was positively correlated with ER and PR expression (x2 =0.448,P ＜ 0.01).Conclusion Absence or down-regulated expression of KLK10 may play an important role in the formation and development of endometrioid adenocarcinoma.The low expression of KLK10 is correlated with low expression of ER and PR in endometrioid adenocarcinoma.The positive expression of KLK00,ER and PR predicts a better prognosis.

AIM: Humanized-NOD/SCID(hu-NOD/SCID) mouse model was established and the level of immune reconstitution was assessed in this model. METHODS: Mononuclear cells (MNC) and CD34+ cells were isolated or sorted from cord blood(CB). Human CD45, CD19, CD3 markers on cells from NOD/SCID murine peripheral blood(PB), bone marrow(BM), thymus were detected by FCM from 4 to 10 weeks after hematopoietic stem cell transplantation. After 10 weeks, the gene expressions of the human ?2M and RAG2 were detected by RT-PCR in PB or bone marrow of mice model. RESULTS: Human CD45, CD19, CD3 cells populations in PB and BM were found by flow cytometry in mice model transplanted with CD34+ cells or CB MNC from 4 to 10 weeks. The highest positivity of human lymphocytes was at 8 week after transplantation. The levels of human cell engraftment in mice transplanted with CD34+ cells were higher than those in mice transplanted with CB MNC. The mRNA of human ?2M and RAG2 were found by RT-PCR in BM.CONCLUSION: The higher level of human lymphocyte engraftment is established in NOD/SCID mouse model transplanted with CD34+ compared with CB MNC. The maturation of T lymphocytes could be happened in bone marrow of mice model.

Objective To study the risk factors of intracranial hemorrhage after endovascular therapy of cere-bral arteriovenous malformations embolization.Methods the clinical records and images of 230 patients with cAVMs were retrospectively reviewed.Patients with intracranial hemorrhage after endovascular therapy in 3 days were recorded and the risk factors of hemorrthage by using multivariate logistic regression for guiding the treatment strategy were studied.Results There were 15 patients occurred intracerebral hemorrhages.After treatment the area of cAVMs was significantly smaller than that before treatment[(2.18 ±0.91)cm vs (6.67 ±1.56)cm],the difference lvas a statis-tically significant (t =9.627,P <0.05).A partial AVM reduction of ≥36.5%(P =0.031)and hypertension(P =0.025)were considered as risk factors for hemorrhage after endovascular therapy of cAVWs.Conclusion Patients receives a partial AVMreduction of ≥36.5% or with hypertension history have a tendancy of increasing hemorrhage after endovascular therapy of cAVMs.It's helpful for preventing intracerebral hemorrhage if the arterial blood pressure maintains after endovascular therapy.

PURPOSE: In the present study, we investigated the incidence of cardiotoxicity within 5 years of trastuzumab treatment and evaluated potential risk factors in clinical practice. METHODS: The study cohort included 415 patients diagnosed with early breast cancer (EBC). Cardiotoxicity incidence was evaluated in patients receiving trastuzumab and those who did not. Multivariate Cox proportional hazards regression models were used to estimate hazard ratios and 95% confidence intervals of potential risk factors for trastuzumab-related cardiotoxicity after appropriate adjustments. RESULTS: Incidence of cardiotoxicity in patients treated with trastuzumab was significantly higher than that in controls (23.7% vs. 10.8%, p<0.001). This result was adjusted for factors that might increase the risk of cardiotoxicity, such as history of coronary artery diseases or the use of anthracyclines for more than four cycles. CONCLUSION: Our findings indicated that treatment with trastuzumab was strongly associated with cardiotoxicity in EBC patients.

Objective:To assess the influence of age on the safety of propofol mono-sedation for adult patients undergoing painless gastroscopy.Methods:A retrospective study was conducted on data of 321 patients scheduled for painless gastroscopy with propofol mono-sedation. According to the age, patients were divided into youth group (116 cases, 18-44 years), middle-aged group (103 cases, 45-59 years) and elderly group (102 cases, 60-80 years). The procedure time, the total dosage of propofol, the occurrence of airway obstruction or hypoxemia, the use of airway interventions including airway opening maneuvers and facemask ventilation, lowest SpO 2, adverse cardiovascular events (including hypertension, hypotension, tachycardia, and bradycardia), and the use of ephedrine during painless gastroscopy were observed. Results:There was significant difference regarding the total dosage of propofol among youth group (173.2±47.0 mg), middle-aged group (158.8±41.3 mg) and elderly group (137.8±26.3 mg) ( F=21.761, P<0.001). The total dosage of propofol was significantly lower in the elderly group compared with the middle-aged group ( P<0.017) and youth group ( P<0.017), and that in the middle-aged group was significantly lower than that in the youth group ( P<0.017). The incidence of hypoxemia was 12.9% (15/116) in the youth group, 15.5% (16/103) in the middle-aged group and 25.5% (26/102) in the elderly group, with significant difference among three groups ( χ2=5.711, P=0.017). Moreover, the incidence of hypoxemia was significantly higher in the elderly group compared with the middle-aged group ( P<0.017) and youth group ( P<0.017). The incidences of hypotension, bradycardia and total adverse cardiovascular events were 5.2% (6/116), 4.9% (5/103) and 11.8% (12/102), 1.7% (2/116), 2.9% (3/103) and 7.8% (8/102), and 11.2% (13/116), 10.7% (11/103) and 20.6% (21/102) respectively in youth, the middle-aged and the elderly group. There were no significant differences in the above indicators among the three groups ( P>0.05). However, compared with those of the young and the middle-aged patients, the occurrence of hypotension, bradycardia and total adverse cardiovascular events in the elderly patients were on the rise. There were no significant differences among the three groups in other indices( P>0.05). Conclusion:Total dosage of propofol may need to be decreased gradually with the increase of age of patients undergoing gastroscopy with propofol mono-sedation. Compared with young and middle-aged patients, elderly patients have a significantly higher incidence of hypoxemia, with a tendancy of total adverse cardiovascular events increase, so the safety of painless gastroscopy is reduced for these patients.
