RESUMO
Objective To detect the levels of serum fatty factor complement C1q tumor necrosis factor-related protein (CTRP) 3 and CTRP9 in pre-eclampsia (PE) pregnant women,and to analyze their correlations with the levels of glucose metabolism and lipid metabolism indexes.Methods From January 2016 to March 2018,96 pregnant women with mild pre-eclampsia and 90 pregnant women with severe preeclampsia were selected,another 100 healthy pregnant women were selected as control group.The levels of serum CTRP3 and CTRP9 were detected by enzyme linked immunosorbent assay (ELISA);the levels of triglyceride (TG),cholesterol (TC),low density lipoprotein cholesterol (LDL),high density lipoprotein cholesterol (HDL),free fatty acid (FFA),and fasting blood glucose (FPG) were measured by automatic biochemical analyzer;fasting insulin level (FINS) was measured by automatic chemiluminescence instrument.The insulin resistance index (HOMA-IR) was calculated and the differences among the three groups were compared.Pearson was used to analyze the correlation between the levels of CTRP3 and CTRP9 and the indexes of glycolipid metabolism.Results The serum CTRP3 and CTRP9 levels of PE patients in severe group and mild group were significantly lower than those in control group (P ＜ 0.05),and serum CTRP3 and CTRP9 levels in severe PE patients were significantly lower than those in mild PE patients (P ＜ 0.05);the serum lipid metabolism indexes levels of FFA,TG,TC,and LDL of PE patients in severe group and mild group were significantly higher than those in control group (P ＜ 0.05),and HDL level was significantly lower than that of the control group (P ＜ 0.05);the levels of serum lipid metabolism indexes FFA,TG,TC,and LDL of PE patients in severe group were significantly higher than those in mild group (P ＜ 0.05),and the level of HDL was significantly lower than that in mild group (P ＜ 0.05).The levels of serum glucose metabolism indexes FPG,FINS,and HOMA-IR of PE patients in severe group and mild group were significantly higher than those in control group (P ＜ 0.05);the levels of FPG,FINS,and HOMA-IR in severe PE patients were significantly higher than those in mild PE patients (P ＜ 0.05).Pearson test showed that serum CTRP3 and CTRP9 levels in PE patients were negatively correlated with FFA,TG,TC,FPG,FINS,and HOMA-IR levels (P ＜ 0.05),and positively correlated with HDL level (P ＜ 0.05).Conclusions The levels of serum CTRP3 and CTRP9 are decreased in PE patients,which is negatively correlated with FFA,TG,TC,FPG,FINS,and HOMA-IR levels,and positively correlated with HDL level.They may be indirectly involved in the pathogenesis and progression of PE by affecting the glycolipid metabolism in pregnant women.
RESUMO
Objective To explore the value of Color Doppler Flow Imaging in diagnosis of superfi-cial substantial tumors.Methods Retrospective analysis of 742 cases of superficial substantial masses ( all confirmed by operation and pathology) of Patients'ultrasonography , and summarized its features of benign and malignant, and made a comparison.Results Of the 742 patients, ultrasound detection rate of 100%, including 12 cases of malignant lesions, ultrasound diagnosis of 12 malignant cases, the accuracy rate of 100%;730 cases of benign lesions, ultrasound diagnosis of 711 cases of benign, qualitative accuracy rate 97.4%.Conclusions Color Doppler Flow Imaging has an important value in the diagnosis of benign and malignant of superficial substantial tumors.
RESUMO
Objective To visualize the pelvic floor structures by translabial three‐dimensional(3D) ultrasonography performed during labor and immediately after delivery, and to observe the morphological changes of levator hiatus in intrapartum women. Methods Totally 62 nulliparous women with singleton pregnancy and cephalic presentation in labor ward underwent intrapartum translabial 3D ultrasound examination before cervical dilatation, at 10 cm dilatation and immediately after delivery. Volume datasets were obtained at rest, biometric measurements and observation of the morphological changes of levator hiatus in different stages were determined in the axial plane. Comparative analyses of parameters in three stages were carried out. Results Translabial 3D ultrasound demonstrated the pelvic floor structures of intrapartum women well. All biometric measurements of the hiatus before cervical dilatation were the smallest and became the largest at 10 cm dilatation, showed statistically significant differences. The measurements after delivery got smaller immediately but still significantly larger than those before cervical dilatation ( P <0 0.01). Conclusions Translabial 3D ultrasound examination of the pelvic floor during labor and within the first 2h after delivery is feasible. It seems to be an effective tool to visualize pelvic floor structures in intrapartum women. Hiatal enlargement may be a common consequence of vaginal childbirth.
RESUMO
Objective To evaluate the effect of free NgR-modified bone marrow stromal cell (BMSC) transplantation on axon regeneration in rats after spinal cord injury. Methods Genes encoding free NgR protein were cloned and transduced into BMSCs at passage 3 using a lentivirus vector.Indirect immunofluorescence was used to detect the expression of free NgR protein.Meanwhile a spinal cord contusion model was established in 36 adult Sprague-Dawley rats at the T10 segment.The rats were then divided randomly into an experimental group and a control group.NgR + BMSCs were transplanted into the injured site 1 week post-trauma in the experimental group.BMSCs were also transplanted at the same time into the control group.Expression of free NgR at the injury site was detected by immunohistochemical staining at 1 week post-transplantation.The functional recovery of both groups was evaluated at 4 and 6 weeks post-transplantation.Longitudinal sections of the spinal cord were studied for axon regeneration using horseradish peroxidase staining. Results Expression of free NgR was found in the cell plasma of BMSCs by indirect immunofluorescence post-transfection.Positive immunohistochemical staining for NgR was found at the transplant site in the experimental group 1 week post-transplantation.Better axon plasticity could be observed in the experimental group.The Basso-Beattie-Bresnahan scoring of the experimental group was significantly higher than that of the controls at both observation times. Conclusions Free NgR-modified BMSCs can prompt injured axons to regenerate and thus to promote the recovery of neurological function.This might provide a new strategy to treat spinal cord injury.
RESUMO
Polysaccharides from Dendrobium huoshanense possess immunostimulating activity, antioxidant activity and anticataract activity. In order to produce the active polysaccharides from Dendrobium huoshanense through cell culture, we investigated the effects of salicylic acid on cell growth, accumulation of polysaccharides and utilization of carbon source in suspension cultures of protocorm-like bodies from Dendrobium huoshanense. Although salicylic acid slightly inhibited the cell growth, it was beneficial to the utilization of carbon source, thus leading to significant increase in the contents of polysaccharides. The highest polysaccharide production occurred on the medium supplied with 100 micromoI/L salicylic acid. After 18 days of culture the production of polysaccharides reached 3.129 g/L, which was 1.63 times that of the control. Further, we established the kinetic models describing cell growth, polysaccharide production and carbon source utilization based on Logistic equation, Luedeking-Piret equation and Luedeking-Piret-Like equation. The calculated values from the kinetic models showed a good fit to the experimental values, suggesting that salicylic acid could be an effective compound to enhance the production of active polysaccharides from protcorm-like bodies from Dendrobium huoshanense.

METHODS: The appearance, major structure and application of the revolving distribution stand for external remedy was introduced. RESULTS: The revolving distribution stand for external remedy was applicable for the distribution of the viscous liquid preparation, due to which, the work intensity of pharmacists could be reduced and the angle of stand can be adjusted to achieve the best distribution effect. CONCLUSION: The revolving distribution stand for external remedy can be widely used in small-sized hospital preparation room.
