OBJECTIVE:To study the possible mechanism of Bushenshengsui I(BSSS I),a kind of compound Chinese herbs,in treatment of aplastic anaemiaMETHODS:The animal model of mice with aplastic anaemia was established by 60Co irradiationThe therapeutic effects of BSSS I on aplastic anaemia were observed with the changes of peripheral blood cell count,bone marrow GM-CFU-c and activities of blood IL-1,IL-2 and IL-6RESULTS:After treatment with BSSS I,the peripheral blood cell count,amount of bone marrow karyocyte and GM-CFU-c of bone marrow of the aplastic anaemia mice elevated markedly,and the blood IL-1 and IL-6 activities increased obviouslyThe levels of IL-6 increased to the level of normal and showed positive relationship with IL-1(r=0904)The levels of IL-2 of the treatment group showed a decrease but with no significant differencesCONCLUSION:The results showed that BSSS I may improve the function of hematopoiesis by elevating the peripheral blood cells and the amount of bone marrow karyocytes,accelerating GM-CFU-c of bone marrow,and through moderating the activities of IL-1,IL-2,IL-6

Objective To study the characteristics, therapies and prognosis of the patients with epithelial ovarian cancer (EOC) that are initially categorized as extra abdominal adenocarcinoma of unknown primary Methods Twenty five patients with EOC, who were treated in the Cancer Hospital of Fudan University from Jan 1986 to Dec 1997, and manifesting as extra peritoneal or liver parenchyma metastases at the time of presentation, without detectable ovarian tumors, were retrospectively studied Results Supraclavicular and inguinal lymph node metastases were common in this group of patients, with 6 and 5 cases respectively, and 6 patients with more than two sites metastases simultaneously 16 patients (64%) were optimally surgical debulked 20 patients with stage Ⅳ EOC initially presenting as extra abdominal metastases experienced a better prognosis, with an estimated median survival of 24 months. Of whom the median survival was 30 months in patients presenting with pleural effusion or supraclavicular lymph node metastases Vs 19 months in those with other sites spread ( P =0 026 4) Conclusions The prognosis of such cases, particularly for those with supraclavicular lymphadenopathy or malignant pleural effusion, is a lot better than other stage Ⅳ EOC patients, probably because of most of the patients initially presenting with distant metastases being generally in a good condition competent for aggressive surgery or multi cycle chemotherapy

6) of platinum based intravenous chemotherapy prolonged the survival of patients with suboptimal cytoreduction Intraperitoneal chemotherapy was one of the dominant long term survival determinants, and mainly on those with size of residual disease less than 1 cm

1cm, there was a significant statistical difference in median survival of 61 and 12 months, respectively (? 2 =16.60, P =0.0001). The median survival for patients with and without peritoneal chemotherapy were 27 and 12 months, respectively (? 2 =3.45, P =0.0633). Residual disease, FIGO stage, recurrent ascites, uterus muscle involvement were independent prognostic determinants of survival identified by Cox's stepwise regression analysis. Conclusions Aggressive surgical cytoreduction should be performed in elderly AEOC patients as well as in younger patients, but multi-course platinum-based chemotherapy should be used in accordance with the performance status of elder women.

Serum vitamin E was determined using bathopllenanthroline by microspe-ctrophotometric method. The average recovery rate was 93.8 (92.2-98.0) per cent and the coefficients of variation were 2.5 and 7 per cent in high and low levels respectively. This method seems to be quite reliable and sensitive. Of the total 117 serum samples, 30 pairs matched blood for mother and cord, 27 cord blood, and 30 normal adults as control were studied. The mean level of vitamin E in the cord blood was 2.8 ug/ml (?0.9SD), which was about one third of that in the adult. The level of vitamin E in post-partum mother was 12 ?g/ml (?2.5 SD), which was significantly higher than that of nonpregnant women (p

OBJECTIVETo study the concentration change of chemotherapeutic agents in plasma and tissue after intraarterial and intravenous injection.

METHODSTen mature female New Zealand rabbits were divided randomly into two groups. Fluorouracil, etopiside, and cisplatin were injected into the rabbits through the ear vein in one group and through the internal iliac artery in the other group. Blood samples and the uterus tissue specimens were collected at various time points after injection. Drug concentration in plasma and tissue was determined by high performance liquid chromatography (HPLC) method. The data were analyzed by the pharmacokinetic program 3P97.

RESULTSRegular concentration change of the three drugs in plasma and tissue was observed after the intravenous and intraarterial injection, which met the two - compartment model. The pharmacokinetic parameters of the three drugs after intravenous and intraarterial injection were different. The peak concentration in plasma after intraarterial injection was lower than that after intravenous injection and the peak concentration and area under curve (AUC) value in tissue after intraarterial injections were higher than those after intravenous injection.

CONCLUSIONIntraarterial chemotherapy has advantages to intravenous chemotherapy in fluorouracil, etopiside and cisplatin. These advantages depend on the drug pharmacological properties.

OBJECTIVETo study the role of secondary cytoreductive surgery (SCR) in patients with recurrent advanced epithelial ovarian cancer.

METHODSFrom Jan. 1986 to Dec. 1997, 60 women with recurrent advanced epithelial ovarian cancer treated with SCR were retrospectively reviewed. Survival curves were computed using the Kaplan-Meier method with differences in survival estimated by log-rank test. Independent prognostic factors were identified by Cox's stepwise regression, and the affecting factors of SCR evaluated by Logistic stepwise regression.

RESULTSOf the 60 patients, 23 (38.3%) were cytoreduced to small macroscopic residual (

CONCLUSIONSecondary cytoreductive surgery is definitely effective in the treatment of recurrent advanced epithelial ovarian carcinoma, particularly in those who have received primary optimal cytoreduction with a progression-free interval > 12 months and without refractory ascites.

Objective To establish the methods of three-dimensional eonformal(3DCRT) and intensity-modulated radiotherapy(IMRT) for whole pelvic irradiation in post-hysterectomy cervical carcinoma, And to optimize the methods for clinical practice. Methods Between 2004 and 2005,10 patients with cervical carcinoma who underwent hysterectomy with high risk of recurrence were selected for this study. The following observations and measurements were used for the study: Set-up errors with supine or prone position were measured to determine appropriate immobilization position. Influence of full and empty bladder on irradiated normal tissue volume was measured. Treatment errors were detected and CTV/PTV were then delineated. 3DCRT and IMRT planning and comparison were applied. Results The set-up error was within 5 mm of three dimensions in prone position and more than 5 mm in supine position, the difference of which was statistically significant. The percentage of irradiated volume of the bladder and bowel was smaller when the bladder was full comparing with empty bladder. In prone position and with full bladder,portal films showed the movement of isocenter in three directions. The total uncertainty was [7.4±1.6]mm. For 95% confidence interval,the margin from CTV to PTV was 1 cm. CIPTV for 3,4,5,and 6 fields 3DCRT was 0.46,O. 67, O. 68, and O. 68, respectively. When beyond 4 fields, the advantage of adding fields was not significant.Four fields planning was feasible for clinical practice. CI for 5,7,9,11 ,and 13 fidds IMRT was 0.75,0.83, 0.84,0.85 ,and 0.85 ,respectively. When beyond 9 fields,the advantage of adding fields was not significant. Nine fields planning was feasible for clinical practice. Conclusions For whole pelvic radiotherapy for post-hysterectomy cervical carcinoma,prone position was better than supine position for immobilization due to smaller set-up errors. The full bladder is recommended during radiotherapy, planning,For clinical practice,4 fields planning is feasible in 3DCRT while 9 fields planning is feasible in IMRT.
