Objective To explore the diagnostic value of plasma fetal DNA level in preeclampsia.Methods Thirty cases of pregnant women with preeclampsia(at 33 weeks and 3 days) and 30 cases of normal pregnant women(at 34 weeks and 3 days) were selected.All the pregnant women carried a male fetus by B-ultrasound,and were sampled at gestational 20 weeks,third trimester and at 1 hour,3 hours,6 hours after delivery.SRY levels in maternal blood were quantitated by polymerase chain reaction(QF-PCR).The endotheliotoxin(ET) level was measured with RIA.Results (1) Mean fetal DNA level of patients with preeclampsia at 20 weeks of gestation was(316?61)copy/ml.They were(266?79)copy/ml,(396?91)copy/ml,(165?43) copy/ml for light and severe preeclampsia women and normal pregnant women,respectively.Maternal blood fetal DNA levels in pregnant women with preeclampsia at 20-weeks of gestation were significantly higher than those normal pregnant women(P

Objective To explore the effect of non-invasive labor analgesia on postnatal depression among primipara. Methods Three hundred primipara of spontaneous labor in our hospital from February 2014 to April 2014 were assigned as control group and another 300 primiparas of spontaneous labor from May 2014 to August 2014 as experiment group. In the control group, one-to-one responsibility system was conducted for the delivery with an accompanying midwife and in the experiment group, non-invasive labor analgesia was done apart from one-to-one responsibility system. The two groups were compared in terms of analgesic effect at three stages of labor, postnatal depression scores and incidence of postnatal depression. Result The analgesic effect of the experiment group was better than that of the control group during the three stages of labor (all P<0.01), and postnatal depression scores and the incidence of postnatal depression in the experiment group were significantly lower than those in the control group (both P<0.05). Conclusion Non-invasive labor analgesia can relieve the labor pains and decrease the incidence of postnatal depression among primiparas.

Objective:To assess the potential of mouse immune-costimulating signal B7-2 in inducing immune effect.Methods:(1)The specific mB7-2cDNA fragment from LPS-stimulated mouse splenocytes was obtained by reverse transcription and polymerase chain reaction.The obtained fragment was inserted to pLXSN plasmid.Then the plasmid pLXSN-mB7-2 was packaged into PA317 cells;(2)The EL4/mB7-2 was obtained by infecting the EL4 by the concentrated virus particles produced by PA317/mB7-2;(3)In vitro,the secretion of IL-2 of EL4/mB7-2 stimulated-lymphocytes was detected by using mixed lymphocytes culture.Results:pLXSN-mB7-2 and transgenetic EL4/mB7-2 cells were obained successfully.IL-2 production in 24h in the supernatant stimulated by EL4/mB7-2 was much higher than wild EL4 cells.Conclusion:EL4/mB7-2 can activated T cell to produce IL-2.This research lay foundation for the research of the function of immune-costimulating signal in the tumor immunity and treatment,the mechanism of autoimmune disease and organ transplantation.

Objective To detect fat emboli in cardiac chamber of the patients undergoing total knee arthroplasty(TKA) by transesophageal echocardiography(TEE), and to discuss the relevant clinical value.Methods Eleven female patients with 12 osteoarthritis(OA) knees were underwent TKA. According to whether using tourniquet or not,12 knees were divided into 2 groups at random:tourniquet-related group (6 knees) and control group(6 knees). Echo intensity and ultrasonic characteristics of fat emboli in cardiac chamber were studied dynamically by multiplane TEE in various periods of the whole operation. Results All of the patients were implanted knee prostheses successfully. In different periods of TKA, fat emboli appeared as isoechoic or hyperechoic particles, which were found in right atrium, but nothing could be found in left heart. The imaging of the particles was flowing with duration time of 10～600s, like dots, lines, "moving star" or "shower". While femur expanding(0～3mins),the particles in right atrium and ventricle became more and more, and the echo intensity became significantly higher than those in other periods. After releasing tourniquet(0～5mins),most particles with highest echo intensity were observed in right heart,showing like "snowstorm" in tourniquet-related group, and more emboli were still detected at the end of monitoring (10 min after releasing tourniquet) by TEE,compared to the control group. No patient suffered from fat embolism syndrome(FES) with clinical manifestation. Conclusions Fat emboli in cardiac chamber can be observed sensitively by real-time TEE dynamically during TKA. It should be encouraged and promoted to analyze ultrasonic characteristics to facilitate the early detection, early diagnosis and early clinical intervention for the subclinical type of FES.

The changes of expression and function of MDM2 and P53 by MDM2 specific antisense oligonucleotides were investigated in HL60 cells. Cells were divided into control group, AS group (MDM2 specific antisense oligonucleotides group), cisplatin group, and combined treatment group. FCM analysis and Western blot and RT-PCR were used to estimate apoptosis and the expression of MDM2 and P53. Our results showed that the transfection of MDM2 specific antisense oligonucleotides obviously inhibited MDM2 expression (P < 0.01) and increased the expression of P53 (P < 0.05). Apoptosis rate were reduced by MDM2 specific antisense oligonucletides and cisplatin (P < 0.01). It is concluded that MDM2 specific antisense oligonucletides can inhibit the expression of MDM2, induce the expression of P53 and increase the apoptosis of leukemia cells after chemotherapy.

Objective To investigate the effect of perfusion index of the injection flow rate of contrast medium on magnetic resonance image dynamic contrast-enhanced (DCE-MRI) of prostate cancer with different pathological grades. Methods Seventy patients with PCa、cardiac, normal renal function is and BMI≤25 kg/m2 were enrolled. The 2.5 mL/s, 5.0 mL/s dynamic enhanced injection velocity contrast agent was used for 35 patients and the reast 35 patients, respectively. All data was transferred to GE Advanced Workstation 4.3, and the indexes of the peripheral prostate cancerous zone were calculated by Functool2 of signal intensity time (SI-T), The time to minimum (Tmax), the whole enhancement degree (SImax%) and the maximum slope (Rmax) were calculated. The effect of different injection velocity on the dynamic enhanced perfusion index was analyzed. Results Tmax of pa-tients received 2.5 mL/s, 5.0 mL/s contrast agent injection velocity in the low risk group (Gleason score 2 to 6)、medium risk group (7 Gleason score) and high risk group (Gleason score 8 to 10) were (19.89 ± 2.76) s and (15.42 ± 1.68) s, (16.91 ± 2.34) s and (12.88 ± 1.73) s, (14.13 ± 1.81) s and (10.2 ± 1.42) s, with signifi-cant differences (t = 4.61, 3.1, 3.25, P < 0.01). The average SImax% of PCa in the two groups were (1.45 ± 0.17)%and (1.51 ± 0.27)%, (1.62 ± 0.12)%and (1.84 ± 0.18)%, (1.86 ± 0.16)% and (2.11 ± 0.28)%, Two groups of SImax% were statistically significant difference (t = -2.44, -4.55, -5.16, P < 0.05), respectively. The average Rmax of PCa of the two groups were (6.29 ± 2.62)% and (7.64 ± 4.09)%,(8.92 ± 4.21)% and (10.24 ± 9.09)%, (10.85 ± 2.89)% and (12.43 ± 3.51)%, with significant difference (t = -4.07,-3.85, -8.68, P <0.01). Tmax was shorter, SImax% and Rmax were higher of prostate cancer patients received 5.0 mL/s contrast agent injection velocity than those received 2.5 mL/s contrast agent injection velocity. Conclusion The dynamic enhancement perfusion index of prostate cancer patients received 5.0 mL/s contrast agent injection velocity is more sensitive than that of patients received 2.5 mL/s contrast agent injection velocity , which can improve the diagnosis of prostate cancer.
