International Journal of Traditional Chinese Medicine 2008;30(5):365-366
Objective To observe the effects of termination of pregnancy with Guizlfi Fuling Capsule plus Mifepristone.Methods 75 early pregnant women were randomly recruited into a treatment group and a control group.Women in the control group were applied with Mifepristone plus Misoprostoi.Form the 3rd day,women in the treatmcnt group were applied wilh Guizhi Fuling Capsule(3 times daily,and 3 granules for each time)for successive 7 days oil the basis of medicines used in the control group.Compared and analyzed the therapeutic effects of both groups.Results The average time for ovum evacuation in the control group and the tretment group was(6±1.8)h and(3±2.6)h separately.Besides both bleeding volume and bleeding time in the Izeatment group were lower than the eonlxol group.Conelusion Guizhi Fuling Capsule plus Mifeoristolle therapy will shorten ovum evacuation time and decrease bleeding volume.
2.Application of Medial Collateral Ligament Release Technique in Knee Arthroscopic Surgery for Medial Tibiofemoral Compartment Tightness
Chinese Journal of Minimally Invasive Surgery 2016;16(2):177-180
Because of the factors such as degeneration or congenital dysplasia which leads to medial tibiofemoral compartment tightness, the arthroscopic surgery of this part might have limited vision and narrow operating space, which causes missed diagnosis and iatrogenic injury.Medial collateral ligament ( MCL) release technique is a simple, effective and safe procedure.By releasing part of the ligament fiber, this operation can effectively expand the visual field and operation space.avoiding the risk of iatrogenic injury of cartilage and missed diagnosis.MCL release technique is an effective method to solve the arthroscopic examination and endoscopic operation for medial compartment tightness of the knee joint.This article reviewed the technique of MCL release.

The study of glomerular mesangial cells of normal rats showed that angiotensin Ⅱ (ATⅡ) down-regulated the expression of MMP-2 mRNA, did not have significant effect on TIMP-2 mRNA. And in consequence, ATⅡ down-regulated the ratio of MMP-2 mRNA to TIMP-2 mRNA.

Objective To study the effects of hypoxic preconditioning on the Fos and Jun expression and apoptosis in cultured rat hippocampal neurons after anoxia\|reoxygenation. Methods The hippocampal neurons cultured for 12d from control and hypoxic\|preconditioning groups were exposed to anoxia environment (0\^90?l/L N\-2+0\^10?l/L CO\-2) for 4h and than reoxygenated for 24h and 72h.The expression of Fos and Jun were revealed immunocytochemically using the antiserum against Fos and Jun.The apoptosis was examied using the terminal deoxynucleotidyl transferese\|mediated biotinylated deoxyuridine triphosphate nickel and labeling(TUNEL) method and flow cytometric analysis. Results The increased of percentage of Fos and Jun positive neurons and apoptosis neurons in cultured hippocampal neurons after anoxia\|reoxygenation than those in befor anoxia.The precentage of Fos and Jun positive neurons and apoptosis neurons were less in the hypoxic\|preconditioning group than that in control aftre anoxia\|reoxygenation.Conclusion\ Hypoxic\|preconditioning increases tolerance of hippocampal neurons to anoxia and decreases the precentage in Fos and Jun expressing neurons and apoptosis neurons in hippocampus aftre anoxia\|reoxygenation in vitro. \;[

Ultrasound diffraction tomography (UDT) possesses the characteristics of high resolution, sensitive to dense tissue, and has high application value in clinics. To suppress the artifact and improve the quality of reconstructed image, classical interpolation method needs to be improved by increasing the number of projections and channels, which will increase the scanning time and the complexity of the imaging system. In this study, we tried to accurately reconstruct the object from limited projection based on compressed sensing. Firstly, we illuminated the object from random angles with limited number of projections. Then we obtained spatial frequency samples through Fourier diffraction theory. Secondly, we formulated the inverse problem of UDT by exploring the sparsity of the object. Thirdly, we solved the inverse problem by conjugate gradient method to reconstruct the object. We accurately reconstructed the object using the proposed method. Not only can the proposed method save scanning time to reduce the distortion by respiratory movement, but also can reduce cost and complexity of the system. Compared to the interpolation method, our method can reduce the reconstruction error and improve the structural similarity.

Objective To investigate the influence of intraoperative posture intervention on drainage in patients after gynecological laparoscopic surgery. Methods A total of 1250 patients who were scheduled for gynecological laparoscopic surgery including laparoscopic-assisted salpingoplasty,oophorocystectomy,ectopic pregnancy,vaginal hysterectomy,myomectomy and appendectomy were randomly divided into two groups. The patients' posture was changed from Trendelenburg position to level lithotomic position during suction by the circulating nurses in the experimental group,while after surgery in the control group. The volume and time of drainage,and the length of stay after surgery were compared between the two groups. Results The volume and time of drainage,as well as the length of stay after surgery had significant differences between the two groups (P<0.05). Conclusions Intraoperative posture intervention is helpful for the treatment effect of drainage after gynecological laparoscopic surgery.
