ObjectiveTo study the influence of EmbryoGlue on the implantation of embryo and pregnancy outcome in vitro fertilization (IVF)-embryo transfer (ET).Methods From August 2010 to January 2011,243 infertile patients in Reproductive Medical Center of Tianjin Medical University General Hospital who underwent IVF or intracytoplasmic sperm injection (ICSI) were divided into two groups,including 129 cases used EmbryoGlue as the embryo transfer medium in experimental group and 114 cases used G-2 as embryo transfer medium in control group.Pregnancy outcome were compared between two groups.Results (1) The female age,IVF/ICSI constituent ratio,previous failure cycles and infertile factors of patients did not show statistical difference between experimental group and control group (P ＞0.05 ).(2) The implantation rate of women in experimental group increased significantly compared with the control group [ 30.4％ ( 85/280 ) vs.18.8％ ( 48/255 ),P ＜ 0.05 ] ; Clinical pregnancy rate increased significantly compared with the control group [48.8％ (63/129) vs.34.2％ (39/114),P ＜0.05] ; Multiple pregnancy rate increased significantly compared with the control group [ 34.9％ (22/63) vs.20.5％(8/39),P ＜ 0.05 ] ; Ectopic pregnancy rate decreased significantly compared with the control group [ 4.8％(3/63) vs.17.9％ ( 7/39 ),P ＜ 0.05 ].ConclusionEmbryoGlue can facilitate embryo implantation in IVF-ET and reduce the occurrence of ectopic pregnancy.

ObjectiveTo investigate the effect of immunoglobulin G (IgG) extravasated from blood circulation on the expression of toll-like receptor 4 (TLR4) induced by peripheral lipopolysaccharide (LPS) in rat brain. Methods The rats were divided into four groups in random, 5 rats in each. Group one received LPS 100μg/kg by intraperitoneal administration, normal saline was given by intravenous injection 6 hours later; group two was injected with adrenalin (AD) 15μg/kg intravenously; group three was treated with LPS intraperitoneally, AD was injected 6 hours later; group four was injected normal saline intravenously as control. For all groups, the animals were sacrificed 30 min after the last injection, and the brains were taken for investigation of the TLR4 expressions by immunofluorescence staining and RT-PCR. Result Immunofluorescence staining showed that IgG immunoreactive product was patch-like, distributed in the brain parenchyma in all the animals that received AD. In the LPS+normal saline group, IgG was found merely around the blood vessels. Meanwhile, in LPS+AD animals, TLR4 immunoreactive product coexisted with microglia marker Iba-1 within the IgG extravasated area. The double-labeled cells dispersed in the brain parenchyma and near to the cerebral vessels. In the LPS+saline group, TLR4 positive cells were endothelial-like. RT-PCR results indicated that the expression level of TLR4 in the LPS+AD group were significantly higher than that in the LPS+saline group or AD group or the saline control (P<0.01). Conclusion Extravasated circulating IgG may enhance the TLR4 expression in the rat brain induced by peripheral LPS.

Objective To evaluate the correlations between CT features and histopathologic subtypes of lung adenocarcinomas presenting as pure ground-glass nodules (pGGN) of 1 cm or less in maximal diameter. Methods CT appearances, pathology and clinical data of 95 patients (97 lesions) who underwent curative resection of lung adenocarcinomas presenting as pGGN≤1 cm in diameter from March 2011 to February 2015 were retrospectively analyzed. Of the 97 lung adenocarcinomas, there were 19 atypical adenomatous hyperplasia (AAH) (19.6%), 31 adenocarcinoma in situ (AIS) (31.9%), 19 minimally invasive adenocarcinoma (MIA) (19.6%) and 28 invasive pulmonary adenocarcinoma (IPA) (28.9%). Fifty (51.5%) were preinvasive (AAH+AIS) and 47 (48.5%) were invasive (MIA+IPA). Lesion size and density were compared among pathologic subtypes using analysis of variance (ANOVA). Lesion size were compared between preinvasive and invasive lesions using 2?independent samples t?test. Lesion location, presence of bubble?like sign, air bronchogram, vessel changes, margin, and tumor?lung interface were compared among histopathologic subtypes using chi?square test. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the cut-off point of size in discriminating preinvasive lesions from invasive lesions. Results Of the 97 lesions, there were no statistically significant differences among histopathologic subtypes in terms of lesion density, presence of bubble?like sign, air?bronchogram, and margin (P>0.05). Mean size of AAH, AIS, MIA and IPA was (0.72 ± 0.19), (0.82 ± 0.14), (0.84 ± 0.11) and (0.85 ± 0.16) cm respectively. There were statistically significant differences among histopathologic subtypes in terms of lesion size (F=3.16, P=0.028). The vessel changes occurred in 2 of AAH, 11 of AIS, 10 of MIA and 17 of IPA. There were statistically significant differences among histopathologic subtypes in terms of vessel changes (χ2=13.22, P=0.004). Lesions with clear tumor?lung interface were in 10 of AAH, 24 of AIS, 17 of MIA, and 26 of IPA. There were statistically significant differences among histopathologic subtypes in terms of tumor?lung interface (χ2=12.67, P=0.005). The optimal cutoff value of lesion size for differentiating preinvasive lesions from invasive lesions was 0.82 cm (sensitivity, 61.7%;specificity, 62.0%). Conclusion Lesion size, vessel changes, and lung?tumor interface may indicate the invasiveness of lung adenocarcinoma presenting as pGGNs of≤1 cm in diameter.

Methods 80 cervical cancer patients after total hysterectomy were divided into the treatment group and the control group with 40 cases in each group stochastically. The treatment group was given systemic nursing( psychological nursing,pelvis bottom muscles exercising,urination discontinuance exercising,abdominal muscle exercising,Valsalva maneuver exercising, Crede press exercising,open the urethral catheter timely and individually,cheiropractic with hot roller), the control group received conventional nursing and some simple training of urinary bladder function. The time of indwelling urethral catheter after the hysterectomy was compared. Results The time of indwelling urethral catheter in the treatment group and in the control group were (9.65±49)days and (15.88±03)days respectively. The incidence rate of residual urine,urine retention and infection of urinary system after surgery in the treatment group was lower than that of the control group. Conclusions Early systemic nursing intervention can shorten the time of indwelling urethral catheter after hysterectomy, reduce the occurrence of urinary bladder dysfunction .improve the surgery effect for the cervical cancer patients and ameliorate their quality of life.

Objective To analyze the clinicopathological characteristics and prognosis of different subtypes of breast cancer patients with bone metastasis.Methods For this study, we recruited 300 primary breast cancer patients with bone metastasis treated at the Department of Oncology, the First Affiliated Hospital of Xi`an Jiaotong University, between September 1, 2007 and September 1, 2011.We also retrospectively analyzed their clinical and follow-up data.Results The percentage of Luminal A, Luminal B, human epidermal growth factor receptor-2 (HER-2) overexpression and triple negative subtypes in all the bone metastatic breast cancer patients was 59.0％, 16.0％, 13.7％ and 11.3％, respectively.Age, tumor size and histologic grade significantly differed among the four subtypes (P<0.05).However, there were no significant differences in menopausal status, lymph node metastasis, histological type or lymphovascular invasion among different subtypes (P>0.05).The median survival time of Luminal A breast cancer patients with bone metastasis was 28.6 months, longer than Luminal B (26.9 months), HER-2 overexpression (20.9 months) and triple negative breast cancer patients (12.0 months) with bone metastasis.The overall survival significantly differed among the patients with four subtypes of breast cancer.Conclusion Different subtypes of breast cancer patients with bone metastasis have different clinical characteristics and prognosis.Luminal A breast cancer patients with bone metastasis have better prognosis whereas triple negative subtype has poorer prognosis.

OBJECTIVETo investigate the protect effects of sodium ferulate (SF) on the daunormbicin(DNR-induced cardiotoxicity in juvenile rats.

METHODSForty male juvenile SD rats were randomly divided into control group (Control), daunorubicin group (DNR), sodium ferudate treatment group (DNR + SF), sodium ferudate group (SF) (n = 10) . Juvenile rats were intraperitoneally treated with DNR (2.5 mg/kg every week for a cumulative dose of 10 mg/kg) preparation immature myocardial injury model in presence with SF (60 mg/kg) oral treat- ment for 25 days. The left ventricular pressure and its response to isoproterenol were measured using left ventricular catheter. Rat myocardium myocardial pathology specimens and ultrastructure changes were also observed. The expression of cardiac Troponin I (cTNI) was detected by Western blot and RT-PCR. Results: SF treatment could inhibit the decreasing of heart rates induced by DNR damage (P < 0.05); it could increase the left ventrivular end diastolic pressure(LVEDP), heart rate, the maximal left ventrivular systolic speed(LVP + dp/dtmax) and the maximal left ventrivular diastolic speed (LVP-dp/dtmax) responding to isoproterenol stimulation(P < 0.01); SF also could improve the myocardial ultrastructure injuries and inhibit the decreasing of cTNI expression caused by DNR damages (P < 0.05).

CONCLUSIONSF treatment could alleviate the decreasing of cardiac reservation induced by DNR damages in juvenile rats, which might be related to its reversing the effects on the cardiac systolic and diastolic function injuries and its inhibiting effects on the decreasing of cTNI expression caused by DNR. The mechanism of SF preventing daunorubicin-induced cardiotoxicity in juvenile rats is relevant to inhabited cardiac Troponin I expression.

Objective To clarify the role of the virtual reality (VR)in the training of trans-femoral cerebral angiography for novices without any experience of intravascular manipulation. Methods Twenty-four novices without experiences of intravascular manipulation were divided into 2 groups (VR group or control group)with random pair method concerning the age,gender and subjects. The par-ticipants in control group were trained in routine manners while those in VR group practiced on a simulator and subsequently participated in real angiography once as assistants. Real angiography tests were performed for all participants after the training session and additional angiography tests were per-formed for VR group just after the stimulation session on the simulator. Real angiography tests were supervised and scored according to a modified rating scale by neuroradiological experts who were blinded to the novices' training procedures. Difference between the real test performance of the two groups were compared by pared-samples t test,while the correlation between the performance of the real tests and simulator tests of VR group was proved by Pearson correlation analysis. P<0.05 was con-sidered statistically significant. Results The mean scores of VR group were (27.6±3.6)and (26.4± 3.8)in the tests on simulator and real angiography tests respectively,while score of control group was (21.2±3.4)in the real angiography tests. A positive correlation was revealed in VR group between performance on the simulator and that on real patients (r=0.825,P=0.001). Real performance of the VR group was significantly better than that of control group (P=0.010). Conclusions Virtual reality could ensure transfer of acquired endovascular skills from simulators to patients so as to become a valid tool for novices to improve the interventional techniques in tranfemoral cerebral angiography.
