Objective To explore the effect of preoperative chemotherapy for children with malignant extragonadial germinoma. Methods Twenty patients with malignant extrogonadal germinoma had been treated with preoperative chemotherapy from Mar.2003 to Mar.2007.Protocol 1 of chemotherapy was to improve PEB:(cisplatin plus etoposide plus bleomycin A5);Protocol 2 was VAC(vincristine plus actinomycin D plus cyclophosphamide) the average time span of the chemotherapy was 16 weeks.Upon completion of chemotherapy,tumor resection was performed.The content of alpha fetoprotein(AFP) was determined before operation and compared with the content before chemotherapy.Re-gular follow-up procedure was taken after operation. Results All 20 patients received chemotherapy and underwent operation.The removal rate of resection operation was 100%,the process of operation was smooth.The volume of tumors in 14 patients decreased over 50% compared with those before chemotherapy.The response rate was 70%.The content of AFP decreased significantly in 15 patients(75%).Fifteen patients had been living without tumor for up to 2 years,for 5 cases the survival time went beyond 5 years. Conclusions Malignant extrogonadal ger-minoma in children grow infiltratively,bring detrimental effects to neighboring organs,and bring obstacles to resection operation.Chemotherapy for children with malignant extragonadal germinoma before operation can reduce volume of tumor and bleeding during operation,raise the resectability rate and lower the content of AFP.It will enhance the effectiveness of operation and improve prognosis.Therefore,it can be used as a conventional clinical method.

OBJECTIVETo study and compare the effect of neutrophil elastase inhibitors (GW311616A and sivelestat) on the proliferation and apoptosis of U937 cells.

METHODSInhibitory effects of GW311616A and sivelestat on the proliferation of U937 cells were assayed by MTT assay. The morphologic changes of U937 cells were detected by transmission electron microscope, and apoptosis was observed by AnnexinV-FITC/PI staining. The changes of cell cycle and apoptosis were detected by flow cytometry. The expression of NE in U937 cells was observed by indirect immunofluorescence, the variations of content and activity of NE in U937 cells were measured through ELISA assay and colorimetric method.

RESULTSMTT showed that both NE inhibitors could inhibit the proliferation of U937 cells in a dose dependent manner. The IC50 of GW311616A and sivelestat were 150 and 214 μmol/L respectively. The inhibition effect of GW311616A was significantly higher than of sivelestat (P<0.01). Typical apoptosis morphological changes of U937 cells was observed through electron microscope. AnnexinV-FITC/PI staining showed that U937 cells could be induced to undergo apoptosis by the two inhibitors, the apoptosis ratio of 150μmol/L GW311616A group (13.60%) was significantly higher than that of 150μmol/L sivelestat group (3.69%)(P<0.01). The result of flow cytometry indicated that the apoptosis ratio of 150 μmol/L GW311616A group was 14.61%, U937 cell cycle was mainly blocked in G2/M phase; meanwhile 150 μmol/L sivelestat group as 4.25% with cell cycle in S phase. The fluorescence intensity of GW311616A group obviously decreased than of sivelestat group. And the two inhibitors could reduce the content and activity of NE in U937 cells, but the effect of GW311616A was significantly higher than of sivelestat (P<0.01).

CONCLUSIONGW311616A and sivelestat could inhibit the proliferation and cause apoptosis of U937 cells. Furthermore, GW311616A was more effective and harmful to cells than sivelestat.

OBJECTIVETo observe clinical efficacy of plum-blossom needle for follicular maldevelopment (FM).

METHODSFifty cases of FM were randomly divided into a plum-blossom needle group and a medication group, 25 cases in each one. In the plum-blossom needle group, the plum-blossom needle was applied along Thoroughfare, Conception, Governor and Belt Vessel as well as at Pishu (BL 20), Weishu (BL 21), Shenshu (BL 23), Luanchao (Extra), Zigong (EX-CA 1) during the follicular growth phase, once every other day. In the medication group, clomifene (CC) was prescribed for oral administration and human choriogonadotropin (HCG) was given by intramuscular injection, once each day. For both groups, one menstrual cycle constituted one course. After two courses of treatment, follicular development condition, the changes of endometrial thickness and morphology, ovarian resistent index (RI) and pulsatility index (PI), rate of ovulation and pregnancy were compared between the two groups.

RESULTSAfter the treatment, the average diameters of the biggest follicle increased in both groups, while the endometrial thickness and morphology in the plum-blossom needle group were superior to those in the medication group (all P < 0.05). Ovarian RI and PI during mature follicular phase in the plum-blossom needle group were inferior to those in the medication group (both P < 0.05). The differences in ovulation and pregnancy rate were not significant statistically between the two groups (both P > 0.05).

CONCLUSIONThe plum-blossom needle therapy based on regulating Thoroughfare, Conception, Governor and Belt Vessel could improve the ovarian blood perfusion, promote the follicular growth, increase the ovulation rate of mature follicle and avoid the out-of-sync between growth of follicle and endometrium during the treatment of western medication.
