METHODS It was to count the bacteria and white blood cells in 422 urine specimens with UF-100 as well as to culture the specimens quantitatively.Then the sensitivity and specificity of UF-100 counts and the correspondence of the two methods were evaluated with Yerushalmy mode. RESULTS Compared with the culture results,UF-100 showed a sensitivity of 81.5%,specificity of 63.9%,positive predictive value of 29.1%,negative predictive value of 95.0%,false positive rate of 30.5%,false negative rate of 2.8% and an accuracy of 67.2%. CONCLUSIONS The UF-100 is excellent in analyzing urine specimens,and its bacteria counts can be a valuable indicator in screening hospital urinary tract infection.

Objective:To evaluate the effects of vitamin K 2 on sevoflurane-induced cognitive decline in aged mice. Methods:A total of 72 SPF healthy female C57BL/6J mice, aged 12 months, weighing 20-25 g, were divided into 4 groups ( n=18 each) using a random number table method: control+ corn oil group (group Con+ Oil), sevoflurane+ corn oil group (group Sevo+ Oil), control+ vitamin K 2 group (group Con+ K 2) and sevoflurane+ vitamin K 2 group (group Sevo+ K 2). The mice in Sevo+ Oil and Sevo+ K 2 groups were anesthetized with 2.5% sevoflurane+ 33% oxygen for 2 h. The mice in Con+ Oil and Con+ K 2 groups were treated with 33% oxygen only.The animals in Con+ Oil and Sevo+ Oil groups were intraperitoneally injected with corn oil 100 μl at 30 min before oxygen or sevoflurane inhalation.Vitamin K 2 (dissolved in corn oil, concentration 1 mg/ml) 100 mg/kg was injected intraperitoneally in Con+ K 2 and Sevo+ K 2 groups.At 24 h after sevoflurane inhalation, 8 mice from each group were randomly selected and sacrificed, and the hippocampal tissues were removed for determination of activity of ATPase, contents of interleukin-1beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) (by enzyme-linked immunosorbent assay) and the expression of AT8 and PHF1 (by Western blot). The remaining 10 mice in each group received standardized feeding, and the cognitive function was assessed using Y-maze at 1, 3, 5, 7 and 14 days after sevoflurane inhalation. Results:Compared with group Con+ Oil, the contents of IL-1β, IL-6 and TNF-α were significantly increased, expression of AT8 and PHF1 were up-regulated, activity of ATPase was decreased, and spontaneous alternation percentage was decreased at 1, 3, 5, 7 and 14 days after sevoflurane inhalation in group Sevo+ Oil ( P<0.05). Compared with group Sevo+ Oil, the contents of IL-1β, IL-6 and TNF-α were significantly decreased, expression of AT8 and PHF1 were down-regulated, activity of ATPase was increased, and spontaneous alternation percentage was increased at 1, 3, 5, 7 and 14 days in group Sevo+ K 2 ( P<0.05). There was no significant difference in the above indicators between group Con+ K 2 and group Sevo+ K 2 ( P>0.05). Conclusion:Vitamin K 2 can improve sevoflurane-induced cognitive decline in aged mice, the mechanism is related to increasing activity of ATPase and inhibiting the up-regulation of AT8 and PHF1 expression in hippocampus.

Background and purpose: Multidrug resistance of tumor cells is the main factor for the failure of chemotherapy. It is found that the apigenin has the anti-tumor effect, but its role in multidrug resistant cells was rarely reported. This study aimed to investigate the effect of apigenin on multidrug resistant breast cancer cell line MCF-7/ADR, and to explore the role of apigenin in reversing multidrug resistance. Methods: The MCF-7/ADR cells were cultured with different concentrations of apigenin, and the same cells were cultured with ADR in the control group. Thecell proliferation was detected by MTT, the cell cycle distribution was detected by PI, and the cell apoptosis was detect-ed by Annexin V/PI. The drug sensitivity in vitro was detected by the method of MTT, and the drug retention rate was detected by rhodamine 123 accumulation. The expression of P-gp protein was measured by Western blot, the RT-PCR method was used to detect the transcription of multidrug resistance gene MDR1. Results: The MCF-7/ADR cell prolif-eration was inhibited by the apigenin, the cell cycle progression was blocked by the apigenin, and the cell apoptosis was induced by the apigenin. There were significant differences between the apigenin group and the ADR group (P<0.05). The IC50 of ADR on MCF-7/ADR cell was (12.37±0.18) μg/mL with the apigenin effect, while the IC50 of ADR on MCF-7/ADR cell was (39.83±0.29) μg/mL without the apigenin effect (P<0.05). The reversal index was 3.22. The retention rate of rhodamine 123 in MCF-7/ADR cells in the apigenin group was higher than that in the ADR group. The MDR1 gene transcription level in MCF-7/ADR cells was higher than that in the MCF-7 cells, and the P-gp expression in MCF-7/ADR cells was higher than that in the MCF-7 cells. However, the level of MDR1 gene transcription and P-gp expression were down-regulated by the apigenin in the MCF-7/ADR cells. Conclusion: The apigenin had anti-MCF-7/ADR effect, and played the role of reversing multidrug resistance in the MCF-7/ADR cells. The mechanism may be related to down-regulation of the MDR1 gene transcription and the P-gp mediated drug e?ux function.

Objective To compare the effects of propofol versus midazolam on serum hydrocortisone in the aged traumatic brain injury. Methods 64 patients (aged 65-72 years) with traumatic brain injury during mechanical ventilation were divided into propofol group (n=32) and midazolam group(n=32).The hemodynamics data,intracranial pressure(ICP) and the calculated cerebral perfusion pressure(CPP) were recorded.The serum hydrocortisone of patients was detectedby enzyme linked immunosorbent assay (ELISA) at 24 h,72 h and 4 weeks in intensive care unit(ICU). Results There was no differences in partial pressure of carbon dioxide,heart rate,meanartery pressure,pulse biood oxygen saturation (SpO2 ),armpit temperature,endexpiratory gas(PEr CO2),intraeranial pressure (ICP) and cerebral pertusion pressure (CPP) between the two groups (P＞0.05).The serum hydrocortisone in propofol group at 24 h and 72 h [(269.7±43.2) nmol/L and (235.0±67.0) nmol/L] were lower than in midazolam group [(278.0±75.5) nmol/L and (243.2±42.4) nmol/L] (t=5.312 and 5.919,both P=0.000).The serum hydrocortisone in propofol and midazolam group at 4 weeks were (209.1±73.9) nmol/L and (210.8±66.6) nmol/L,respectively,no significant difference was found(t=0.075,P =0.938). Conclusions There is a significant difference in the effects of propofol and midazolam on the early level of hydrocortisone in the aged patients with traumatic brain injury.

BACKGROUND: Choriocarcinoma is a kind of trophoblastic neoplasm with highly aggressive phenotypes. Forkhead box D3 (FoxD3) is an embryonic and trophoblastic stem cel transcription factor. It plays important roles in different physical and pathological situations such as embryogenesis, carcinogenesis and tumor progression.
OBJECTIVE:To investigate the role of FoxD3 in choriocarcinoma malignancy and the possible mechanism.
METHODS:The human choriocarcinoma JAR cel line was employed in this study. The mRNA and protein expressions of genes were measured by quantitative RT-PCR (qRT-PCR) and western blot, respectively. The FoxD3 specific short hair RNA was applied to down-regulate gene expression. The cel proliferation was evaluatedin vitro by cel counting assay andin vivo by tumor growth. The migration/invasion was determined by transwel assay. The profile of FoxD3 targeted genes was investigated with an Agilent microarray and verified by qRT-PCR.
RESULTS AND CONCLUSION: The FoxD3 mRNA and protein expressions in JAR cells were significantly higher than those in primarily cultured normal trophoblastic cells. Knockdown of FoxD3 by short hair RNA in JAR cells could inhibit cell proliferation and migration/invasionin vitro, and suppress thetumor growth with decreased β-human chorionic gonadotropin secretionin vivo. A profile of seven focal adhesion molecules (ITGA5, ITGB6, THBS4, COL6A3, VTN, NRXN3 and NLGN1) was verified to be targeted by FoxD3. Furthermore, knockdown of FoxD3 by short hair RNA could decrease the activation of focal adhesion kinase. All these findings suggest the overexpression of FoxD3 can contribute to the aggressive phenotype of choriocarcinoma JAR cells by regulating the profile of focal adhesion molecules and focal adhesion kinase.
