Objective To evaluate the diagnostic value of power Doppler ultrasonography through vagina in malignant trophoblastic tumor(MTT).Methods The features of power Doppler flow imaging of 43 cases with MTT were studied retrospectively.The imaging differences in normal group,benign gestational trophoblastic tumors and malignant gestational tropho-blastic tumors were compared,and the relationship between imaging character and benign or malignant gestational trophoblastic tumors was analyzed.At the same time,the change of blood flow in uterine intramuscular layer was obeserved before and after chemotherapy combined with β-hCG.Results The blood folw character of uterine intramuscular layer in normal group was punctate and scattered blood flow signal,flow shape was regular;The blood folw character of uterine intramuscular layer in benign gestational trophoblastic tumors group was short pole blood flow signal,flow shape was less regular;The blood folw character of uterine intramuscular layer in malignant gestational trophoblastic tumors group was very rich blood flow signal,flow shape was anomalistic; After chemotherapy,the extent and diameter of the blood folw of uterine intramuscular layer was decreased seriously,while the β-hCG reduced.Conclusion PDI had diagnostic value in MTT and could be seemed as a guide for observing the chemotherapeutic effect and prognosis of MTT.

Objective To study the effects of manganese on the expression of caspase-3 and cytochrome-c in the spermatogenic cells of rats. Methods Forty-eight male SD rats were randomly divided into the high dose,low dose exposure groups and the control groups,16 in each,were given manganese(MnCl2?4H2O) at 15,30 mg/kg and normal saline,I.P. once a day, 5 times a week,for 6 consecutive weeks. In the 4th and 6th weekend,the testis were collected,the expression of caspase-3 and cytochrome-c in the testis was determined by immunohistochemical methods (SABC). Results The caspase-3-positive-cell rate in the spermatogenic cells of rats in the high dose and low dose exposure groups increased significantly (P

WANG Ji's opinion on moxibustion therapy in Questions and answers of acupuncture and moxibustion (Zhenjiu Wendui) was explored and analyzed. With his two contraindications of moxibustion as breakthrough points, the arrangement and discussion was performed. The results showed that based on summary of moxibustion treatment theory before Ming dynasty, WANG Ji could provide characteristic idea, which is of great reference value and guide significance to the inheritance and development of moxibustion.

With deep acupuncture at Baliao points (eight sacral foramina) as the core, Professor WANG Ling-ling has treated diseases of urinary, digestive and reproductive systems with superior therapeutic effect. The key for efficacy of Baliao points is deep acupuncture. Only deeply insert into acupoints with long needles and directly stimulate at sacral nerves, could Baliao points play a superior role in treatment effect. Searching acupoints is the basis of deep acupuncture, and superficial anatomy should be combined to summarize the methods of searching Baliao points. The premise of deep acupuncture is needling manipulation. The angles of needles must be adjusted according to morphological features of posterior sacral foramina, or it is hard to practice deep acupuncture into Baliao points. The description of location and manipulation on Baliao points in ancient and modern literature was vague, which restricts clinical application of Baliao points. A lot of research on location, manipulation and clinical application of Baliao points has performed by Professor WANG Ling-ling, and its manipulation and clinical cases are introduced to make a positive effect on its application and popularization.

Objective To evaluate autologous buccal mucosal patch grafting for correcting penile deformity in the surgical treatment of Peyronie's disease. Methods 14 patients with symptoms of Peyronie's disease for more than three months suffered from persistent pain ,severe curvature of the penile shaft and resistant to conservative treatment underwent plaque incision and autologous buccal mucosa patch grafting. Results Postoperative follow up has been 0.5 to 2years.The penile shaft became straight with no narrowing or indentation in 12 patients (86%) . In 14% of cases (2/14) some curvature of the penile shaft persisted and there was pain on erection.In all the patients there was no change in penile length. 86% of patients had overall satisfaction after surgery with improvement in psychological and social well-being. Conclusions The autologous buccal mucosal patch graft provides an anatomical and functional tunied substitute resulting in correction of the penile deformity in Peyronie's disease.

OBJECTIVETo study the effect of Ti-TiO2 nanotubes with different diameters on the adhesion of fibroblast and osteoblast, and to find which diameter was more favorable for cells' respective adhesion.

METHODSPure titanium sheets were polished and then anodized at different potentials for 1 h with Ti as anode and Pt as cathode. TiO2 nanotubes formed at 1, 5, 10 and 20 V potentials served as experimental groups and polished pure titanium served as control group. Field emission scanning electron microscopy (Fe-SEM) was used to analyze the surface topography. Stained nucleus with Hoechst33342 were used to measure the cell adhesion. The cell shape on the sample surface were analyzed with Fe-SEM.

RESULTSTiO2 nanotube array of different inner diameters from 15 nm to 100 nm were grown on titanium sheets by anodization at potentials from 1 to 20 V. At 30, 60 and 120 min, fibroblast adhesion at nanotubes anodized at 5 V was (141 ± 9), (388 ± 14) and (489 ± 15) respectively, significantly less than any other nanotube surface at the same time (P < 0.01). Nanotubes anodized at 20 V had the least inhibitory effect for fibroblast adhesion with a number of (579 ± 14) at 120 min, and the cell shape was also inhibited. At 30, 60 and 120 min, osteoblast had a significant better adhesion on nanotubes formed at 5 V than it did on any other surface at the same time (P < 0.01), except the control group at 30 min, with the adhesion number of (198 ± 10), (431 ± 10) and (501 ± 10) respectively, and osteoblast had a abundant spread on nanotubes formed at 5 V; while osteoblast adhesion on nanotubes anodized at 20 V was (152 ± 11), (403 ± 9) and (465 ± 12) respectively, less than on any other nanotube surface within the same time (P < 0.05), and the cell shape on the surface changed to be more elongate.

CONCLUSIONSFibroblast adhesion is inhabited more or less on Ti-TiO2 nanotubes of different diameters. Nanotubes formed at 5 V have the most osteoblast adhesion, and inhibit fibroblast adhesion.

Objective To evaluate the multi-slice spiral CT scan of liver dynamic dual-phase three-dimensional vascular imaging portal phase clinical value. Methods 80 cases in clinic, who were patients with liver function and imaging diagno- sis of liver and portal hypertension in liver cirrhosis, and 20 cases of healthy persons were carried out multi-slice spiral CT dual-phase scanning. The workstation used volume rendering techniques (VR) and maximum density multi-planar recon- struction technique for reconstruction. Results The hepatic arterial phase VR image and MIP MPR images can clearly show the celiac trunk, splenic artery, hepatic artery or artery and its branches, including 2-3 grade tumor blood supply variation of blood vessels and blood vessels, the portal venous phase, VR images and MIP MPR images clearly show the 1-6 level structure and the portal vein and hepatic vein branches of 1-3, with strong three-dimensional sense of space. Conclusion The multi-slice spiral CT three-dimensional reconstruction of portal vein imaging is a fast and effective non-invasive an- giography techniques, contributing to the clinical choice of reasonable efficacy of treatment programs and follow-up.
