Objective To compare the effect of diversification rehabilitation team mode on function in patients with cerebral infarction. Methods Sixty-six patients with cerebral infarction were divided into diversification rehabilitation team mode group (diversification group) and routine rehabilitation mode (routine group) according to the rehabililation method with 33 cases each. All patients of 2 groups were treated for 2 weeks. Evaluations were made before and after treatment. The simplified Fugl-Meyer motor function rating scale was used to evaluate motor function, modified Barthel index was used to evaluate activities of daily living, and MOS 36-item short form health survey was used to evaluate quality of life;and 0-100 digital simulation assessment was used to evaluate patient satisfaction after treatment. Results The simplified Fugl-Meyer motor function rating scale score, modified Barthel index score, MOS 36-item short form health survey score and patient satisfaction rate after treatment in diversification group were significantly better than those in routine group: (76 ± 4) scores vs. (63 ± 3) scores, (65 ± 3) scores vs. (52 ± 4 ) scores, (57 ± 7) scores vs. (44 ± 6) scores, (92 ± 5) scores vs. (77 ± 3) scores, and there were statistical differences (P<0.05). Conclusions Both kinds of rehabilitation model can promote functional recovery in patients with cerebral infarction, but diversification rehabilitation team model is better than conventional model.

Objective To compare the changes of physiological parameters after cardiac arrest caused by asphyxia with that of cardiac arrest induced by ventricular fibrillation in rats and assess the values of the parameters on predicting ROSC and 24 h survival rate. Method Two groups of Sprague-Dwaley rats, which randomly (ramdom number) included 30 animals in each group, were investigated. Cardiac arrest were induced by asphyxia (AS group) or ventricular fibrillation(VF group). PETCO2, aortic pressure, left ventricular pressure and ECG of limb lead Ⅱ were recorded continuously, dP/dt4o was calculated with the windaq software. The parameters were compared between the two groups at baseline, precordial compression(PC) 10 s, PC 1 min, PC 3 min, ROSC 1 h and ROSC 2 h. The relations were explored between the parameters and ROSC/24 h survival rate. Results PETCO2,aortic pressure, left ventricular pressure and ECG have distinctive changes in the two groups. In group VF, PETCO2 of ROSC rats at BL, PC 1 min and PC 3 min were higher than those of Non-ROSC rats (P ＜ 0.05); PETCO2of 24 h survival rats at ROSC 1 h and ROSC 2 h were higher than those of 24 h death rats (P ＜ 0.05), which were not observed in the group AS. dP/dt40 and - dP/dt40 at ROSC 1 h and ROSC 2 h in group VF were higher than those in group AS (P ＜ 0.05). Conclusions Physiological parameters after cardiac arrest caused by asphyxia or that of cardiac arrest induced by ventricular fibrillation in rats have unique features respectively. PETCO2 in cardiac arrest caused by ventricular fibrillation may predict ROSC and 24 h survival rate. Researchers have to select the appropriate cardiac arrest model according their research purposes and clinical requirments.

This study aimed to explore the impact of depression caused by chronic unpredictable mild stress (CUMS) on in vivo activity of six kinds of CYP450 isoforms in rats. According to 'Katz' method, the model of CUMS was established. Tolbutamide, chlorzoxazone, theophylline, midazolam, omeprazole and dextromethorphan were chosen as probe substrates of CYP2C6, CYP2E1, CYP1A2, CYP3A2, CYP2D1 and CYP2D2 of rats. Plasma concentration of six kinds of CYP450 in control group and model group were determined by LC-MS/MS and computed pharmacokinetic parameters. Consequently, metabolism of theophylline and chlorzoxazone accelerated significantly (P < 0.01), but tolbutamide, dextromethorphan, omeprazole and midazolam had no significant difference. The present study proved that depression caused by CUMS had strong induction to CYP1A2 and medium induction to CYP2E1.

BACKGROUNDDiagnostic hysteroscopy and directed biopsy has been widely used to evaluate abnormal uterine bleeding. We aimed to explore the value of hysteroscopy and directed biopsy in the diagnosis of endometrial carcinoma.

METHODSTwo hundred and eighty-seven patients with endometrial carcinoma who were treated in Beijing University People's Hospital, Beijing, China were distributed into 2 groups: Group A (90 patients) was examined using hysteroscopy and directed biopsy, and Group B (197 patients) was examined using fractional dilatation and curettage (D&C). The diagnostic veracity of the two methods, the rate of positive peritoneal cytology and the prognosis of the 2 groups were compared.

RESULTSIn Group A, 97.8% (88/90) of patients were diagnosed pathologically before surgery; the rate was 88.8% (175/197) for Group B. The difference between the 2 groups was statistically significant (P < 0.05). The sensitivity, specificity, positive predictive value and negative predictive value for the two methods for detecting cervical involvement were 77.8%, 100%, 100% and 97.6% for Group A and 65.3%, 92.6%, 74.4% and 90.0% for Group B, respectively. The positive peritoneal cytology rate was 5.6% (5/90) in Group A and 6.09% (12/197) in Group B. The difference was not statistically significant (P > 0.05). The 3-year and 5-year overall survival rates were 91.4% (33/36) and 82.4% (14/17) for Group A and 95.6% (87/91) and 86.7% (39/45) for Group B. There were no statistically significant differences between the two groups' survival rates (P > 0.05).

CONCLUSIONCompared with fractional D&C, hysteroscopy and directed biopsy offered improved pathological diagnostic accuracy before surgery and discovered cervical involvement more precisely in endometrial carcinoma patients, but it did not increase the positive peritoneal cytology rate or affect the prognosis of these patients.

This study was aimed to investigate the effect of RPMI 1640 and IMDM on the development of human peripheral blood monocyte-derived dendritic cells. Under the same cytokines and culture conditions, the different medium types were tested, and the morphology of mature and immature dendritic cells was observed by microscopy, the cell phenotype and endocytosis ability were detected by flow cytometry. Furthermore, the immunoregulatory function of various DC was analyzed by mixed lymphocyte reaction (MLR), the expression of cytokine in culture supernatant of MLR system was also analyzed by Bio-plex technology. The results showed that there were no difference in morphology, CD14, CD83 expression and endocytosis ability between IMDM-cultured DC and RPMI-1640 medium-cultured DC, but there was a lower expression of CD1a in IMDM-cultured DC. Moreover, DC cultured with IMDM displayed a significant reduction in stimulating T cell proliferation, and highly expressed IL-6, IL-8 and IL-10, but low expressed IL-12. It is concluded that the different cultural mediums can induce DC with different functions and DC cultured with IMDM may correlated with induction of immune tolerance. The results of this study will provide a new idea for DC clinical application.

In this study,RNA interference technique was employed to silence the expression of DNMT1 and/or DNMT3b in human bladder cancer T24 cells.The expression levels of their mRNA and protein were greatly decreased by up to 75% and 65% respectively after T24 cells were transfected with lipofectamine2000 for 72 h,indicating RNA interference is an effective tool in gene knockdown.Proliferation and apoptosis of T24 cells were detected by MTT,and annexin-V-FITC and propidium iodide staining flow cytometry,respectively.It was found that loss of the DNMT1 or DNMT3b expression could inhibit the cell growth and promote the cell apoptosis to some extent.However,combined treatment with shRNA targeting both DNMT1 and DNMT3b mRNA could ob-viously enhance the above effects.It was concluded that simultaneously silencing both genes could result in strong suppressing effect on tumor proliferation and promoting ceil apoptosis than separate use,suggesting combined use of DNMT1 and DNMT3b can achieve a synergistic effect in the CpG island methylation in human bladder tumorigenesis.

OBJECTIVEVentilator-associated pneumonia (VAP) is a common nosocomial infection and is responsible for a very high mortality in neonatal intensive care unit (NICU) patients. This study was designed to investigate the etiology and high risk factors of neonatal VAP.

METHODSThe clinical data of 106 critical neonates who were treated with mechanical ventilator between 2003 and 2005 were studied retrospectively.

RESULTSOf the 106 neonates, 84 received mechanical ventilation for > or = 48 hrs. Thirty-five (41.7%) out of the 84 patients developed VAP. Univariate analysis showed that gestational age, duration of mechanical ventilation, reintubation, birth weights, primary lung disease and gamma globulin administration were associated with the development of VAP (P < 0.05). Multivariate stepwise logistic regression analysis showed that primary lung disease (OR=3.671, 95% CI=1.0-13.45, P < 0.05), duration of mechanical ventilation (OR=4.945, CI=1.51-16.21, P < 0.01), reintubation (OR=7.721, 95% CI=2.31-25.85, P < 0.01) and high-dose gamma globulin administration (OR=5.520, 95%CI=2.08-16.26, P < 0.01) were predicted factors for the development of VAP. The detection rate of gram negative bacilli (76.9%) was the highest, followed by gram positive coccus (17.9%) in VAP patients.

CONCLUSIONSOpportunistic drug-resistant bacteria are common pathogens for neonatal VAP. The risk of VAP is multifactorial, including external medical environments and patients' internal agents.

OBJECTIVETo investigate the factors influencing the long-term survival of pancreatic carcinoma patients after radical resection.

METHODSThe data of 184 pancreatic carcinoma patients with radical resection were analyzed retrospectively. Analysis of the prognostic factors influencing the long-term survival was performed using Cox proportional hazard regression model.

RESULTSThe overall 1-, 3- and 5-year survival rates in this group were 61.7%, 29.0% and 14.3%, respectively. They were 78.0%, 38.4% and 25.7%, respectively, for the patients with a tumor < 3 cm in diameter, significantly better than those with a tumor >or= 3 cm (52.8%, 22.7% and 7.2%, respectively, P < 0.05). Moreover, the 1-, 3- and 5-year survival rates were 67.6%, 30.5% and 17.4%, respectively, in the patients without lymph node involvement, much longer than that in those with lymph node metastasis (37.1%, 20.6% and 0, respectively, P < 0.05). Multivariate analysis by Cox proportional hazard regression model revealed that the tumor size (P < 0.05) and lymph node metastasis (P < 0.01) significantly influenced the long-term survival of the patients.

CONCLUSIONTumor size and lymph node metastasis are significant factors influencing the long-term survival of pancreatic carcinoma patients with radical resection. Therefore, early diagnosis and radical resection are the key points to improve treatment outcome.
