Objective: To explore the etiology and pregnancy outcome of fetal intrauterine growth restriction(FGR). Methods: 120 cases of FGR pregnant women were selected as the research subjects(FGR group). And 120 healthy pregnant women who were successfully delivered during the same period were selected as the control group.The medical records and pregnancy outcomes in the two groups were analyzed and compared. Results: There was no statistically significant difference in age between the FGR group and the control group (t=1.0978, P>0.05). In the FGR group, the proportions of pregnant women who came from the countryside, without prenatal examination and the choice of cesarean section were significantly higher than those in the control group, and the differences between the two groups were statistically significant(χ²=8.832, 4.842, 7.466, 4.843, all P<0.05). The proportions of pregnancy induced hypertension, heart lung disease, premature rupture of membranes, anemia, oligohydramnios, abnormal umbilical cord, placental abnormalities intrauterine distress and meconium infection and twin pregnant women in the FGR group were significantly higher than those in the control group(χ²=12.810, 4.655, 6.666, 12.860, 16.335, 6.587, 4.629, 6.696, 7.924, 8.038, all P<0.05), these factors were the causative factors of FGR.The neonatal quality and gestational age in the FGR group were (2 134.32±322.17)g and (35.74±2.12)weeks, respectively, which were significantly lower than those in the control group[(2 793.83±427.64)g, (38.23±2.75)weeks](t=13.493, 7.855, all P<0.05). The incidence rates of neonatal morbidity, neonatal asphyxia and neonatal death in the FGR group were 15.00%, 3.33% and 4.17%, respectively, which were significantly higher than 3.33%, 1.67%, 0.00% in the control group(χ²=9.808, 4.668, 5.106, all P<0.05). Conclusion The incidence of FGR is associated with pregnancy induced hypertension, heart lung disease, premature rupture of membranes, anemia, oligohydramnios, abnormal umbilical cord, placental abnormalities intrauterine distress, meconium infection and twins.FGR should be promptly diagnosed and treated in the clinical, can terminate pregnancy when necessary, as soon as possible to improve the adverse pregnancy outcome.Improving the adverse pregnancy outcomes as much as possible can achieve the purpose of eugenics.

The color of Rubus chingii was characterized by digital method, and the content of water extract, alcohol extract, total flavonoids, total polysaccharides, total polyphenols, ellagic acid, linden glycoside, kaophenol-3-O-rutin were determined. Correlation regression was used to analyze the correlation between color and composition. The results showed that L~* was positively correlated with total polyphenols, kaophenol-3-O-rutin and tilide, and moderately positively correlated with total flavones, ellagic acid and aqueous extracts. The a~* value was negatively correlated with total polyphenols, kaophenol-3-O-rutin, and linden glycosides, while was moderately correlated with total flavones, aqueous extracts, and ellagic acid. The b~* value was negatively correlated with the water extract, and moderately correlated with the content of total polyphenols, total polysaccharides, alcohol extract and kaophenol-3-O-rutin, which showed that R. chingii mature color had a significant correlation with material composition in the process of dynamic change. According to the law of dynamic change in the color and quality indexes, it is determined that the appropriate harvest time is in late April to May 1, while the fruit is not turn yellow. The agronomic traits related to fruit was(12.49±0.56) mm in diameter,(14.25±1.19)mm in height,(1.20±0.14) g in weight, the chroma L~* value was 52.87±3.14,a~* value was 2.01±1.58, b~* values was 28.31±3.88. The results lay a foundation for establishing an objective quantitative evaluation model of R. chingii color from experience.

OBJECTIVETo assess the clinical efficacy of acupuncture pretreatment for the prevention of stroke based on promoting the circulation of the Governor Vessel and regulating mentality, and explore its effect mechanism.

METHODSSeventy cases of transient ischemic attack (TIA) were randomized into an acupuncture group (35 cases) and a western medicine group (35 cases). In the acupuncture group, acupuncture therapy of promoting the circulation of the Governor Vessel and regulating mentality was applied at Yaoyangguan (GV 3), Mingmen (GV 4), Zhiyang (GV 9), Shenzhu (GV 12), Dazhui (GV 14), Yamen (GV 15), Fengfu (GV 16), Baihui (GV 20) and Neck-Jiaji (EX-B 2). Acupuncture was given 6 times a week, at the interval of one day between two weeks. Totally, 21 days of treatment were taken as a session. In the western medicine group, aspirin enteric coated tablets were prescribed, 25 mg/tablet, 100 mg/day, once a night for oral administration, and 21 days of medication were taken as 1 session. There were 3 days at the interval between two sessions in each group and totally 2 sessions were required. Transcranial Doppler (TCD) was adopted before treatment and in two sessions of treatment to observe, mean flow velocity (Vm) of middle cerebral artery (MCA), vertebral artery (VA), basilar arte ry (BA) and pulsatility index (PI). The standard of the efficacy assessment of stroke aura was taken as the main efficacy index in the assessment of theraputic effect, the adverse reaction was observed.

RESULTS1In TIA, MCA blood flow was accelerated in internal carotid system, and BA blood flow was accelerated in vertebral-basilar artery system. The treatments in the two groups enabled the blood flow in the responsible blood vessels slow down and the results in the acupuncture group L(60. 54+/-11.76)cm/s, (36. 17+/-8. 65)cm/s] were better than those in the western medicine group [(72. 34+/-9. 15)cm/s,(65. 23 +/-8. 99)cm/s] (P0. 05).

CONCLUSIONAcupuncture intervention based on promoting the circulation of the Governor Vessel and regulating mentality achieves the superior efficacy on TIA and less adverse reactions as compared with aspirin. The effect mechanism is related potentially to the improvement of cerebral vascular hemodynamic.

Objective To study the influence of curcumin on chemosensitivity of nephroblastoma cells. Methods Human nephroblastoma cells line SK-NEP-1 was transplanted to the nude mice subcutaneously to establish the implantation tumor model of human nephroblastoma cells. A total of 30 tumor-bearing mice were divided into three groups of ten randomly. The routine chemotherapy group was given vincristine (0.05 mg/mL·0.2 mL/d) and actinomycin D (15 ng/mL·0.2 mL/d) combined chemotherapy regime. The curcumin chemotherapy group was given the same combined chemotherapy regimens and curcumin (30 mg/kg/d) by intraperitoneal injection. The control group was given normal saline (NS) of the same volume by intraperitoneal injection. Continuous administration would be kept for 4 weeks and 3 days a week. The volumetric changes of every group were recorded. The serum of every group in different time was collected and the VEGF content was detected by ELISA. All mice were cercrificed and the tumor tissues were stripped and weighed after 4 week's treatment. The tumor inhibition rate was calculated. The cell proliferation activity and apoptosis rate were detected by MTT and flow cytometry method. All data were statistically analyzed by SPSS 19.0. Results The tumor volume, serum VEGF content, tumor inhibition rate, cell proliferation activity and apoptosis rate of routine chemotherapy group and curcumin chemotherapy group had significant differences comparing with the control group (P < 0.05) after 4-week's treatment. The cancer growth of curcumin chemotherapy group was obviously decreased and even tended to shrink comparing with routine chemotherapy group (χ
