OBJECTIVETo improve the diagnosis and treatment of testicular teratoma in children by analysis of clinical data.

METHODSWe retrospectively analyzed the clinical data about 64 cases of testicular teratoma treated in the Children's Hospital of Chongqing Medical University from 1995 to 2014.

RESULTSSixty-one of the cases presented painless scrotal mass with a sense of bearing down and the other 3 cases were confirmed because of empty scrotum diagnosed as cryptorchidism. The level of serum alpha fetal protein ( AFP) was obviously increased in 46 cases but normal in the other 18 preoperatively. Ultrasonography manifested abnormal inhomogeneous echo zones with calcification or necrosis. X-ray examination presented patchy or curvilinear high-density shadows in 28 cases. Forty-one of the patients underwent testis-sparing surgery (TSS) , 20 received high inguinal orchiectomy, and 3 refused surgical treatment. Pathological examination revealed 3 mature germinal layers in the 49 cases of mature teratoma and immature germinal tissue, including the original neural tube, and 11 cases of immature teratoma. The mature cases were exempted from chemotherapy, while the immature cases received the combination of cisplatin, etoposide, and bleomycin (PEB). The patients were followed up for 2 years postoperatively, which revealed no recurrence or metastasis.

CONCLUSIONMost children with testicular teratoma presented painless scrotal mass with a sense of bearing down and with abnormal serum AFP in most cases. Ultrasonography and plain radiography of the scrotum contribute to the diagnosis of the tumor. TSS is the main treatment option and intraoperative frozen-section can help the surgeons decide on the surgical mode. Postoperative chemotherapy is necessitated for immature teratoma but not for mature cases.

OBJECTIVE: To determine whether the introducer curving technique is useful in decreasing the degree of tilting of transfemoral Tulip filters. MATERIALS AND METHODS: The study sample group consisted of 108 patients with deep vein thrombosis who were enrolled and planned to undergo thrombolysis, and who accepted transfemoral Tulip filter insertion procedure. The patients were randomly divided into Group C and Group T. The introducer curving technique was Adopted in Group T. The post-implantation filter tilting angle (ACF) was measured in an anteroposterior projection. The retrieval hook adhering to the vascular wall was measured via tangential cavogram during retrieval. RESULTS: The overall average ACF was 5.8 +/- 4.14 degrees. In Group C, the average ACF was 7.1 +/- 4.52 degrees. In Group T, the average ACF was 4.4 +/- 3.20 degrees. The groups displayed a statistically significant difference (t = 3.573, p = 0.001) in ACF. Additionally, the difference of ACF between the left and right approaches turned out to be statistically significant (7.1 +/- 4.59 vs. 5.1 +/- 3.82, t = 2.301, p = 0.023). The proportion of severe tilt (ACF > or = 10degrees) in Group T was significantly lower than that in Group C (9.3% vs. 24.1%, chi2 = 4.267, p = 0.039). Between the groups, the difference in the rate of the retrieval hook adhering to the vascular wall was also statistically significant (2.9% vs. 24.2%, chi2 = 5.030, p = 0.025). CONCLUSION: The introducer curving technique appears to minimize the incidence and extent of transfemoral Tulip filter tilting.

AIMTo investigate the molecular mechanisms of saponins from the rhizome of Anemarrhena asphodeloides Bunge.

METHODSOligonucleotide microarrays consisting of 87 probes representing 87 human cardiovascular disease-related genes were constructed. Effects of saponins on gene expression in human umbilical vein endothelial cells were analyzed by comparing hybridization of Cy 5-labeled cDNAs from saponins-treated human umbilical vein endothelial cells and Cy 3-labeled cDNAs from untreated human umbilical vein endothelial cells.

RESULTSThe results indicate that angiotensinogen gene, alpha 2A-adrenoceptor gene and endothelin-converting enzyme 1 gene were downregulated 2.8, 1.9 and 3.1 folds respectively after human umbilical vein endothelial cells were incubated in medium containing 80 mg.L-1 saponins.

CONCLUSIONThese results suggest that saponins may have beneficial effect on cardiovascular diseases by modulating the function of vein endothial cells and microarray can be used to investigate the biological action of extracts from traditional Chinese medicine.
