Objective To investigate the pregnancy outcome of patients with preeclampsia (PE). Methods The data of 26 206 pregnant and lying-in women were retrospective analyzed who gave birth in Daping Hospital of the Army Medical University from Jan. 1, 2013 to Apr. 30, 2019, diagnosed with the 8th and 9th version of gynecology and obstetrics textbook. Excluding 62 cases of diabetes combined pregnancy, 445 cases of hypothyroidism combined pregnancy, 180 cases of polyhydramnios, 1592 cases of macrosomia (≥4 kg), 89 cases of chronic hypertension with PE, and 629 cases of multifetation. The remaining 23 209 cases, according to the final diagnosis, were divided into PE group (532 cases) which was divided again into mild-PE group (134 cases) and severe-PE groups (398 cases), and the 22 677 remainders acted as the control group. The age, gestational weeks, number of births, mode of delivery, pregnancy complications and neonatal status in the three groups were compared, and the thyroid function among the groups was analyzed in detail. Results The proportion of elderly parturients was higher in both mild-PE group (29.2%) and severe-PE groups (20.6%) than that in control group (12.4%). The rates of premature delivery and cesarean section were higher in both mild-PE group (19.7% and 55.0%) and severe-PE groups (70.1% and 94.2%) than those in control group (10.0% and 48.2%). The incidences of hypothyroidism during pregnancy, intrahepatic cholestasis of pregnancy (ICP) and infants younger than gestational age were higher in both mild-PE group (26.9%, 10.5% and 7.5%) and severe-PE groups (23.9%, 9.3% and 22.1%) than those in control group (17.5%, 3.5% and 2.9%); The incidences of placental abruption and stillborn foetus were obviously higher in severe-PE group (3.8% and 7.3%) than those in control group (0.6% and 0.7%). The incidence of gestational diabetes was significantly higher in mild-PE group (41.8%) than that in control group (30.0%), and of umbilical cord around neck was significantly lower in severe-PE group (17.6%) than that in control group (25.1%). Conclusions The incidences of complications and therapeutic premature delivery in PE patients is increased. Hypothyroidism during pregnancy is a potential risk factor and should be strenuously supervised.

Objective To evaluate the inhibitory effect of 2-(8-hydroxy-6-methoxy-1-oxo-1-H-2-benzopyran-3-Y1) propionic acid (NM-3) on lymphangiogenesis in gastric cancer using orthotopic implantated tumor models of BALB/C nude mice. Methods A BALB/C nude mouse model of transplanted in situ human gastric cancer was established. Twenty-eight nude mice were divided into four groups with 7 each: control group, NM-3 treated group, carboplatin (10 mg/kg) treated group,and NM-3 combiantion group injected with normal saline, 5 mg/kg of NM-3, 10 mg/kg of carboplatin or 5 mg/kg of NM-3, + 10 mg/kg carboplatin, respectively, twice a week for 8 weeks. At the end of the 8th week, all mice were sacrificed for detection of lymphatic microvessel density (LMVD),lymphatic vessel endothelial hyaluranic acid receptor 1 (LYVE-1), podoplanin and Prox-1 byimmunohistochemistry with staining. Results In comparison with control group, the LYVE-1 level in other three groups was decreased with no significant difference (P＞ 0.05). The concentrations of podoplanin and Prox-1 in NM-3 group and combination group decreased significantly than those in control group and carboplatin group (P ＜ 0.05). The number of LMVD in NM-3 group and combination group was 4.72±0.50 and 4.78± 0.38, respectively, which was significantly lower than that in control group (7.35±0.55)and carboplatin group (6.98i0.35, P＜0.05). Conclusion The NM-3 can inhibit the growth of gastric cancer by interfering lymphangiogenesis of gastric cancer.

This study is to establish the methods for determination of iridoid glycosides and triterpenic acids in Corni Fructus and provide technical support for the quality control of Corni Fructus. Morroniside, loganin and sweroside were determined by HPLC-UV method with acetonitrile and 0.1% formic acid as the mobile phase, and the detective wavelength was set at 240 nm. Oleanolic acid and ursolic acid were determined by HPLC-ELSD method with methanol-0.5% ammonium acetate (87:13) as the mobile phase. The results showed that the linear ranges of morroniside, loganin and sweroside were 5.335-213.4 mg · L(-1) (r = 0.9999), 5.515-220.6 mg · L(-1) (r = 1.0000), 1.992-79.68 mg · L(-1) (r = 1.0000), respectively. The average recoveries of the above three iridoid glycosides were 98.49%-99.28% with RSDs of recoveries being less than 2%. The linear ranges of oleanolic acid and ursolic acid were 7.74-154.8 mg · L(-1) (r = 0.9964), 10.82-216.4 mg · L(-1) (r = 0.9996), respectively. The average recoveries of the above two triterpenic acids were 98.11%-99.27% with RSDs of recoveries being less than 3%. The method established in this research is simple, rapid and reliable, and can be used for quality control of Corni Fructus. Furthermore, the research provided experimental data for the improvement of present quality standard of Corni Fructus, which has important significance to guarantee its quality and clinical curative effect.

BACKGROUND:Recent studies found that some factors play important role in the process of denervated muscle atrophy, especial y the feak-headbox transcription factor, is the key element to regulate the denervated muscle atrophy.
OBJECTIVE:To investigate the effect of RNA interference on inhibiting feak-headbox 3a gene expression in vitro.
METHODS:The myoblast cel line L6 were cultured in the 6-wel cel culture plates, then pEGFP-N1 and smal
interfering RNA recombinant plasmid with the same ratio was transfected under the Lipofectamine2000 mediation to optimize the transfection efficiency of the detection system;2μg smal interfering RNA recombinant plasmid of feak-headbox 3a gene were transfected with myoblast cel line L6 for 48 and 72 hours.
RESULTS AND CONCLUSION:At 48 hours after pEGFP-N1 and siRNA recombinant plasmid transfection, a large number of bright green fluorescent displayed under fluorescence microscope with higher transfection efficiency. Real-time quantitative PCR analysis showed that there were significant differences in the sequences of feak-headbox 3a-Ⅰ, feak-headbox 3a-Ⅱ, feak-headbox 3a-Ⅲ, feak-headbox 3a-Ⅳ on feak-headbox 3a mRNA when compared with the control group at 48 and 72 hours after trasfection (P<0.05), and the inhibition effect was more significant at 72
hours after transfection when compared with that at 48 hours after transfection. Western Blot gray analysis showed that there were significant differences in sequences of feak-headbox 3a-Ⅰ, feak-headbox 3a-Ⅱ, feak-headbox 3a-Ⅲ,
feak-headbox 3a-Ⅳ on feak-headbox 3a mRNA when compared with the control group at 48 and 72 hours after
trasfection (P<0.05), and the inhibition effect was more significant at 72 hours after transfection when compared with that at 48 hours after transfection, which was same with the effect on mRNA level. RNA interference in vitro can
significantly inhibit the fork-head transcription factor feak-headbox 3a gene expression, and the inhibition effect of feak-headbox 3a gene smal interfering RNA recombinant plasmid transfected with the sequence on the mRNA and protein level of feak-headbox 3a is not clear, which can provide new idea for the gene therapy of RNA mediated denervated skeletal muscle atrophy.

Objective To evaluate the effect of hydrogen-rich saline on inflammatory responses during transient cerebral ischemia-reperfusion (I/R) in rats.Methods Forty-five male Sprague-Dawley rats,aged 5-6 yr,weighing 180-250 g,were randomly divided into 3 groups (n =15 each) using a random number table:sham operation group (group S),group I/R and hydrogen-rich saline group (group H).The rats were anesthetized with intraperitoneal 10％ chloral hydrate 0.3 ml/100 g.Transient cerebral ischemia was induced by bilateral common carotid artery occlusion with hypotension for 15 min,followed by reperfusion.Five rats were randomly chosen from each group,and Morris water maze was used to assess the cognitive function starting from 5 days before establishment of the model.Place navigation test lasted for 5 consecutive days.The escape latency,swimming speed and swimming distance were recorded.Spatial probe test was carried out on 1 and 3 days after establishment of the model.The time of staying at the target platform quadrant,frequency of crossing the original platform and swimming speed were recorded.The rats were sacrificed after the end of spatial probe test on 3 days after the model was established,and hippocampi were removed to examine the morphology of neurons in hippocampal CA1 region with light microscope.Five rats randomly chosen from each group were sacrificed on 1 day after the model was established,and hippocampi were removed to detect the contents of tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β).The rest 5 rats in each group were sacrificed,and hippocampi were removed for determination of nuclear factor kappa B (NF-κB) activity (by immuno-histochemistry).Results In place navigation test before the model was established,the escape latency and swimming distance were gradually shortened with the prolonging training time,and no significant change was found in the swimming speed with the prolonging training time in the three groups.Compared with group S,the time of staying at the target platform quadrant was significantly shortened,and the frequency of crossing the original platform was reduced on 1 and 3 days after establishment of the model,and the contents of TNF-α and IL-1β and NF-κB activity were increased on 1 day after establishment of the model in group I/R.Compared with group I/R,the time of staying at the target platform quadrant was significantly prolonged,and the frequency of crossing the original platform was increased on 1 and 3 days after establishment of the model,and the contents of TNF-α and IL-1β and NF-κB activity were decreased on 1 day after establishment of the model in group H.There was no significant change in the swimming speed during spatial probe test on 1 and 3 days after establishment of the model.Conclusion The mechanism by which hydrogen-rich saline reduces transient cerebral I/R injury may be related to inhibition of inflammatory responses in rats.
