Chinese Journal of Radiation Oncology 2001;10(2):115-118
Objective To define the rational extent of radiation portal in adult patients with early-stage Hodgkin's disease (HD).Methods From Jan 1984 to Dec 1997,206 adult(≥15 year-old) HD patients with stage Ⅰ~Ⅱ lesions were admitted into the cancer hospital of Chimese Academy of Medical Sciences. 130 cases received radiotherapy alone (RT group). 76 cases radiotherapy combined with chemotherapy (R+C group). Involved-field (IF) was used in 7 patients (3.4%),mantle-field(MF) in 34 (16.5%) patients,subtotal nodal irradiation (STNI) in 140 (68.0%) and total nodal irradiation (TNI) in 25 (12.1%) patients. Kaplan-Meier method was used in survival analysis and log rank test for comparson.Results ①The overall 5-,10-year accumulated survival rates (ASR) were 85.1% and 73.2%. The 5-,10-year disease free survival rates (DFSR) were 68.0% and 63.6%, respectively.② The 5-year ASRs in the MF,STNI and TNI groups were 69.2%,93.3% and 94.4%,respectively (P<0.05);the 5-year DFSRs in these respective groups were 54.2%,79.2% and 79.9% (P<0.05).③ In R+C patients ,the 5-ASRs in the IF/MF and STNI/TNI groups were 75.7% and 90.6%(P<0.05); 5-year DFSRs were 43.1% and 73.3%(P<0.05).Conclusions The stage ⅠA patients with favouable prognostic factors can be cured by using mentle-field only,but patients in the other early-stages should be given subtotal nodal irradiatiion when radiotherapy is given alone. It is suggested that patients with unfavorable prognostic factors should receive radiotherapy combined with chemotherapy.

Objective To assess the value of transcatheter superselective arterial embolization in treatment of renal traumatic hemorrhage. Methods 20 patients underwent digital subtraction angiography with definite diagnosis before embolization. Embolization materials used in the study were gelfoam sponge chips and steel coils including 14 cases of segmental arteries with their branches through superselective renal arterial embolization. 6 cases were treated by selective renal arterial embolization. Results After renal artery embolization, macroscopic hematurin disappeared on 3th to 5th day after the procedure. With an average of 29 months of follow-up, there was no recurrent hemorrhage associated with normal renal function and blood pressure. Conclusions Superselective renal arterial embolization has advantages of less aggression, less complications, and good hemostatic efficacy, with maximal preservation of renal tissue and function for treatment of mild and moderate renal injuries.

Purpose: To analyze the treatment results and detect the prognostic factors for primary gastrointestinal non-Hodgkin'slymphoma (PG-NHL) treated by various treatments. Materials and Methods: 54 PG-NHL patients (19 stage Ⅰ,23 stage Ⅱ, 6 stage Ⅲ and 6 stage Ⅳ patients) were treated from 1983 through 1992. After exploratory,45 patients had gastrotomy and 7, laparotomy. 43 patients were treated by postoperative radiotherapy or chemotherapy or both. Results: The 5-year survival rates ofⅠ~Ⅳ stage were: 94.7%?13.5% ,79.1%?12%, 80%?25.3% and 16.7%? 15.2%. The prognostic factors in PG-NHL were clinical pathologic stages, the volume of the primary tumor and single or multiple foci. Conclusion: Adequate initial surgery combined with postoperation adjunctive R in the upper abdomen for early stage Ⅰ and total abdomen for late stage Ⅰ and Ⅱ, which could be combination C+R following the incomplite resection or unresectable lesions , the tumor dose were 40~45Gy/5~6 wks and the CHOP- BLM program 4~ 6 cyles are benefit for PG-NHL.

Objective To establish the UPLC fingerprint of Shuanghuanglian powder-injection. Methods Acquity UPLCTM BEH C18 Column (2.1 mm × 50 mm, 1.7 μm) was established;mobile phase was acetonitrile and 0.1%formic acid with gradient elution;the flow rate was 0.3 mL/min;the column temperature was 40 ℃. Characteristic spectrum cluster of 13 batches of Shuanghuanglian powder-injection were analyzed, and Chinese Medicine Chromatographic Fingerprint Evaluation System (2004 A) was used to evaluate their quality. Results UPLC fingerprint common mode of 13 batches of Shuanghuanglian powder-injection was established. There were total 16 common spectrum peaks in the reference for comparison, and three main peaks were identified with better separation. The 13 batchs had good consistency, and the process was stable. Conclusion The method is rapid, efficient and can be used for full control of the quality of Shuanghuanglian powder-injection.

OBJECTIVE:To study the improvement effect of Celosia cristata n-butanol extracts on dysfunctional uterine bleed-ing of rats,and explore its mechanism. METHODS:60 pregnant SD rats were randomly divided into blank group,model group, Gongxuening capsule group (positive control,0.07 g/kg) and C. cristata n-butanol extracts high-dose,medium-dose,low-dose groups(4.32,2.16,1.08 g/kg),10 in each group. Except for the blank group,rats in other groups were intragastrically given mife-pristone and misoprostol on 7th of pregnancy for resulting incomplete abortion to induce models of dysfunctional uterine bleeding. Then rats in administration groups were intragastrically given relevant medicines,rats in blank group and model group were intra-gastrically given normal saline once every morning and evening,for 7 d. On 8th d of pregnancy,uterine bleeding amount,and thromboxane (TXA2),prostacyclin (PGI2) and tumor necrosis factor α(TNF-α) contents in serum were determined. RESULTS:Compared with blank group,uterine bleeding amount in model group was significantly increased(P<0.01),TXA2 content in se-rum was significantly reduced,PGI2 and TNF-α contents were significantly increased(P<0.01). Compared with model group,uter-ine bleeding amounts in administration groups were significantly reduced,TXA2 content in serum was significantly increased(P<0.01);PGI2 and TNF-α contents in serum in Gongxuening capsule group and C. cristata n-butanol extracts high-dose group and TNF-α content in serum in C. cristata n-butanol extracts medium-dose group were significantly reduced (P<0.01). CONCLU-SIONS:C. cristata n-butanol extracts show obvious improvement effect on incomplete drug abortion-induced dysfunctional uterine bleeding of rats,and the mechanism may be related to the regulation of TXA2/PGI2 dynamic balance and inhibition of TNF-α tran-sient secretion.

OBJECTIVETo investigate the prognostic value of the size of primary tumor (T staging) and international prognostic index (IPI) for patients with non-Hodgkin's lymphoma (NHL) of the tonsil, and to recommend the treatment strategy for early stage patients.
METHODS306 patients with untreated NHL of the tonsil were reviewed. According to Ann Arbor staging classification, 35 patients had stage I, 178 stage II, 49 stage III and 44 stage IV disease. According to 1997' AJCC staging system, 29 patients had T1, 142 T2, 117 T3 and 18 T4 disease. Twelve stage I patients were given radiotherapy alone and 23 stage II patients were given combined modality therapy (CMT). For patients with stage II lesion, 57 were given radiotherapy alone, 2 chemotherapy alone and 119 CMT. Chemotherapy was the main treatment in patients with stage III or IV lesions.
RESULTSThe 5-year cancer specific survival (CSS) was 74% for patients with T(1), 59% for T(2), 56% for T(3) and 26% for T(4), respectively (P = 0.000). The 5-year CSS was 70% for patients with 0 risk factor, 49% for 1 risk factor, 25% for 2 or 3 risk factor, respectively (P = 0.000). CMT significantly improved disease free survival (DFS) from 46% (radiotherapy alone) to 60% (CMT) for stage II patients (P = 0.046). Multivariate analysis showed that performance status, Ann Arbor staging, T staging, B symptom, and IPI were independent prognostic factors.
CONCLUSIONThe T staging of the primary tumor and IPI are the important prognostic factors of patients with NHL of the tonsil. Combined modality therapy significantly improves the disease free survival of stage II patients.
