0.05).The setting time of hydroxyaptite and glass ions cements with Co-F were longer but there was little effect on zinc phosphate cements. Conclusion The Co-F agent added to dental cement can not only improve the compressive strength but also contin- ually release fluoride.

Objectiye To optimize the depth of the microchannel and the time point for sperm collection,and improve the efficiency of sperm screening on a microfluidic device. Methods Microchannels with four different depths of 25, 50, 100 and 200 μm were tested. Mice sperm were added to the inlet of the microchannel. The relative quantity and motility of sperm in the outlet were recorded at different collection times, i.e. ,5, 15, 30 and 60 min. Statistical method one-way ANOVA and appropriate post-hoc testing were applied to analyze differences between different groups, and further to select the best-fit depth of the microchannel and the time point for collection. Results In microchannels with depths of 25, 50, 100 and 200 μm, the sperm motilities measured in each outlet were (85.4 ± 2.3)%, (85.8 ± 5.8)%,( 87. 2 ± 2. 8 ) %, (76. 5 ± 2. 8 ) % respectively with statistical significance ( F = 5.8, P ＜ 0. 05 ). No obvious differences were found among 25-100 μm channels, however the motility dramatically decreased in the 200 μm group. The relative sperm quantities were (5.2 ±2.0)%, (7.2 ±2.5)%,(12.3 ±2.0)%,(7. 7 ± 1.1 ) % respectively with statistical significance ( F = 6. 9, P ＜ 0. 05), which increased with channel depth from 25 to 100 μm,while it decreased in the 200 μm channel Taking 2 indexes into account, 100 μmwas the most fit channel depth for sperm motility screening. The sperm motility in the outlet gradually decreased with time. At the time points of 5, 15, 30 and 60 min after adding sperm, the sperm motilities were (99. 6 ±0. 7)%, (87.2 ±2. 8)%, (79. 3 ±2. 2)% and (62. 6 ±8.0)% respectively with statistical significance ( F = 37. 3, P ＜ 0. 01 ). Yet the relative quantities of sperm in the outlet increased almost three times in this process. At the time points mentioned above, the relative quantities of sperm were (5.8±1.1)%, (10.6 ± 0.9)%, (12.1 ± 1.7)%, (17.9 ± 3.4)% respectively with statistical significance ( F = 17.8, P ＜ 0. 01 ). Thus 15-30 min was the ideal screening time. Conclusion An effective microdevice for sperm screening with optimized depth and collection time period is developed,which may contribute significantly for the screening of healthy sperm on microfluidic chips.

Polysaccharide materials have no significant effect on the dissolution of the pills. Pills in vitro - in vivo correlation was significant.Conclusion Chinese medicine materials have the characteristics of medicine-assisted unity, which can control the dissolution and bioavailability of pills by adjusting the proportion of powder in the prescription. And the pills have good correlation in vitro - in vivo.

OBJECTIVETo study the effect of Bushen Wenyang Huayu Recipe (BSWYHYR) on nerve growth factor (NGF) and transient receptor potential vanilloid receptor I (TRPV1) in experimental endometriosis (EMT), and to explore its mechanism for treating EMT-induced pain.

METHODSTotally in-bred line BALB/c 75 female mice were divided into five groups, i.e., the sham-operation group, the model group, the high dose BSWYHYR group, the low dose BSWYHYR group, the gestrinone group, 15 in each group. Writhing response was observed in each group. Serum contents of NGF were detected using ELISA. Expression levels of NGF and TRPV1 in uterus and ectopic foci were detected using immunohistochemical staining SP and Western blot. mRNA expression levels of NGF and TRPV1 in uterus and ectopic foci were detected by Real-time PCR.

RESULTSThe serum NGF content in the model group was higher than that in the sham-operation group (P < 0.01), and there was positive correlation between NGF and the writhing frequency (r = 0.574, P < 0.01). Compared with the model group, serum levels of NGF significantly decreased in the 3 treatment groups (P < 0.05). Compared with the sham-operation group, mRNA and protein expression levels of NGF and TRPV1 increased significantly in the model group (P < 0.01). Protein expression levels of NGF and TRPV1 decreased significantly in the 3 treatment groups, when compared with the model group (P < 0.01). mRNA expression levels of NGF and TRPV1 decreased most in the high dose BSWYHYR group (P < 0.01). NGF in uterus and ectopic foci was positively correlated with protein and mRNA expression levels of TRPV1 (P < 0.01).

CONCLUSIONSNGF and TRPV1 participated in the occurrence of pain in EMS. BSWYHYR played an important role in inhibiting EMT-induced pain through reducing the up-regulation of NGF on TRPV1.

Objective Observing changes in thehaemostatic system to determinetheseverity and prognosis of HELLP syndrome. Methods 127 cases of HELLP syndrome diagnosed in Peking University Third Hospital were enrolled from August 2010 to August 2018. Maternal and fetaldemographic characters, postpartum complications,length of hospital stay,prothrombin time(PT),activated partial thromboplastin time (APTT), Fibrinogen(Fg) and D-Dimer(D-D) were collected. Results There was no statistical difference inparturient PT, APTT, D-D levels between maternals of HELLP syndrome with and without postpartum hemorrhage,which were [9.6 (9.0, 11.5)s vs 9.4 (8.9, 9.7)s, P=0.243], [30.2 (29.1, 38.3)s vs 29.8 (27.7, 31.8)s, P=0.151], and [0.80 (0.52, 4.52)μg/ml vs 0.91 (0.55, 2.48)μg/ml, P=0.923] respectively. There was a statistically significant difference obvious difference in parturient Fglevels between two groups [(2.94±1.48) g/L vs (3.61±1.00)g/L, P=0.022). The receiver operating characteristic curve(ROC) analysis showed that the AUC of fibrinogen level when estimating postpartum hemorrhage was 0.688(95％CI:0.600-0.767), cut-off value was 3.04 g/L, negative predictive value was 74.3％. There was a negative correlation between parturient Fg and days of hospital stay of HELLP syndrome maternal(r=-0.182, P=0.040). There was no statistical difference in parturient PT, APTT, Fg and D-D levels between the fetal survival group(n=93) and non-survival group (n=34), and between the distressed group (n=23) and he undistressed group(n=70) (P>0.05). Conclusions The low parturient Fg level may be a risk factor of maternal adverse clinical outcomes in HELLP syndrome. Maintaining the Fg at a stable level may reduce the incidence of HELLP syndrome adverse outcomes.
