Objective To study the rhythmic changes of 24 h ambulatory blood pressure in pre-eclampsia(PE)patients and come up with coping strategies. Method The levels and circadian variations of blood pressures in 240 pre-eclampsia patients were monitored and observed with 24 h ambulatory blood pressure monitoring. Results Among the 240 PE cases,121 were diagnosed as mild PE and 119 as severe PE.There were significant differences in the average of 24 h circadian variation,the average of date time variation,decreased blood pressure at night time between the two groups(all P<0.05). Conclusion Through ambulatory blood pressure monitoring,nurses can monitor the rhythmic changes of 24 h ambulatory blood pressure,make reasonable arrangements for the treatment and care operations,reduce the factors that induce eclampsia and ensure the safety of mother and baby .

Objective To determine the expression of indole-2,3 dioxygenase (IDO) in human acute leukemia,and to investigate its correlations with clinicopathological parameters and prognosis in acute leukemia.Methods The expression of IDO in protein and RNA levels was detected by immunohistochemistry and real-time quantitative RT-PCR,respectively,and the correlations of IDO with clinicopathologic features and prognosis of acute myeloid leukemia (AML)-M5 were analyzed.Results The positive rate of IDO protein was 63.3 ％ (38/60) in human acute leukemia,while it in AML (34/49,69.4 ％),especially in AML-M5 patients (29/35,82.9 ％),was significantly higher than that of acute lymphoblastic leukemia (4/11,36.4 ％).The expression of IDO protein in healthy human peripheral blood mononuclear cells was negative.The RNA expression level of IDO in AML-M5 or non AML-M5 patients were significantly higher than that of healthy people (P ＜ 0.001),and AML-M5 patients had significantly higher IDO RNA level than that in non AML-M5 patients (P ＜ 0.05).The IDO gene expression was not correlated with sex,age and drug sensitivity,while it was closely related with these factors in the patients without complication of pulmonary infection.IDO could not act as an independent prognostic marker.Conclusion The expression of IDO in AML-M5 patients is significantly higher than that in non AML-M5 patients and healthy people.The positive expression of IDO is associated with poor prognosis of AML-M5 patients,but it is not an independent poor prognostic indicator.

Objective To obtain reasonable treatment by urodynamic detection and analysis in patients with diabetic cystopathy (DCP) complicated with benign prostatic hyperplasia (BPH).Methods Sixty patients with DCP complicated with BPH were selected,among the total 32 patients (duration of diabetes ＞ 12 years,blood glucose control was not ideal) were recognized as experimental group,and 28 patients (duration of diabetes ≤ 8 years,blood glucose control was stable) were recognized as control group.Using the Laborie UDS-120XLT urodynamic detection instrument,the urodynamic was detected and the international prostate symptom score (IPSS) was evaluate,and the results were compared between the 2 groups.Results There was no statistical difference in residual urine volume between experimental group and control group [(146 ±71) ml vs.(160 ±64) ml,P ＞0.05].The maximum urinary flow-rate in experimental group was significantly lower than that in control group [(5.4 ± 2.0) ml/s vs.(8.0 ± 3.2) ml/s],the symptom total score of IPSS was significantly higher than that in control group [(25.8 ± 4.1) scores vs.(22.6 ±5.0) scores],there were statistical differences (P ＜0.01).The maximum bladder capacity,compliance,incipient micturition desire volume in experimental group were significantly lower than those in control group,there were statistical differences (P ＜ 0.01).Conclusions The influence of DCP on the function of the bladder in BPH patients is significant.Urodynamic detection can provide objective basis for the selection of therapeutic methods,suitable to be operated and forecast the postoperative effect.It has an important reference value in DCP complicated with BPH patients.

Objective To investigate the expression of suppressor of cytokine signaling genes (SOCSs) and JAKs mRNA in the acute myloid leukemia(AML) patients. Methods The expression of SOCSs and JAKs mRNA as well as TYK2 in AML patients and healthy adults as normal contrals (NC) was measured with RT-PCR. Results The expression of SOCS 1,4,5 and 7 in AML patients was lower than those in normal control and AML with remis-sion (P<0.01),but the expression of SOCS 3 and 6 was higher than those in normal control and remission AML(P<0.01),however there was no significant difference in SOC2 between groups. The expressions of JAK2 ,JAK3 and TYK2 in AML were significantly higher than those in patients with remission and normal control(P<0.05). The ex-pression of JAK1 mRNA in relapsed AML was higher than that in normal control group(P<0.05),but the latter has no statistical significance between beginning treatment and normal group(P>0.05). Conclusion The deletion and degradion of SOCS 1,4,5 and 7 present in AML patients and JAKs expression is significantly increased, suggesting that both of them may co-participate in the pathogenesis of AML.

OBJECTIVETo investigate the synergistic antitumor effects of combined use of p14ARF gene and 5-fluorouracil (5-Fu) in pancreatic cancer.

METHODSA human pancreatic cancer cell line PC-3 was transfected with lipofectin-mediated recombinant p14ARF gene, and was then administered with 5-Fu. Cell growth, morphological changes, cell cycle, apoptosis, and molecular changes were measured using the MTT assay, flow cytometry, RT-PCR, Western blotting, and immunocytochemical assays.

RESULTSAfter transfection of p14ARF, cell growth was obviously inhibited, resulting in an accumulation of cells in the G(1) phase. The proportion of cells in the G(1) phase was significantly increased from 58.51% to 75.92%, and in the S and G(2)/M phases decreased significantly from 20.05% to 12.60%, and from 21.44% to 11.48%, respectively, as compared with those of the control groups. PC-3/p14ARF cells that underwent 5-Fu treatment had significantly greater G(2)/M phase accumulation, from 11.48% to 53.47%. The apoptopic index was increased in PC-3/p14ARF cells from 3.64% to 19.62%. The MTT assay showed p14ARF-expressing cells were significantly more sensitive to 5-Fu (0.01 - 10 mg/L) than those devoid of p14ARF expression (P < 0.01). Western blotting showed p14ARF upregulates p53 expression.

CONCLUSIONCombined use of p14ARF gene and 5-Fu acts synergistically to inhibit pancreatic cancer cell proliferation, suggesting a new anticancer strategy.
