3.Effect of astragalus injection on left ventricular remodeling and apoptotic gene caspase-3 in rats after myocardial infarction.
Chinese Journal of Integrated Traditional and Western Medicine 2005;25(7):646-649
OBJECTIVETo investigate the effect of Astragalus injection (AI) on left ventricular remodeling and the expression of apoptotic gene caspase-3 in rats after myocardial infarction (MI).
METHODSThe MI model was established. The experimental animals were divided into 4 groups, Group I (the sham-operated group), Group II (the sham-operated plus AI group), Group III (the model group), Group IV (the model plus AI group). Animals in the II and IV group were intraperitoneally injected with 2 ml AI once a day after operation, while animals in the I and III group were treated with normal saline of equal volume. After treated for 4 weeks successively, the structural change of left ventricle and the level of oxyproline in myocardium were observed, and expression of caspase-3 was determined by immunohistochemical method.
RESULTSAs compared with Group Ill, the ultrastructure of myocardium and indexes of left ventricular remodeling were improved, the myocardial content of oxyproline decreased (P < 0.05), the caspase-3 positive cells reduced and caspase-3 mRNA expression significantly down-regulated (P < 0.05).
CONCLUSIONAI can improve left ventricular remodeling, inhibit apoptosis by down-regulate the expression of apoptotic gene caspase-3 in rats after MI.

Objective: This study was designed to investigate the prognostic value of serum β2-micorglobulin(β2-MG) level in non-Hodgkin s lymphoma(NHL) patients and its correlation with Ann Arber staging system and the pathological type. Method: Serum β2-MG levels in 75 de novo NHL patients were measured by radioimmunoassay. Results: The β2-MG level in 75 NHL patients was higher than that in nomal control level in 52% of the patients and correlated with the Ann Arber stage. There was significant difference between two groups (P<0.01). The international prognostic index (IPI) and the response rate to chemotherapy were also correlated with the β2-MG level in serum. The response rate, the complete response, and partial response were 87.2%, 61.5%, and 25.6% in normal serum β2-MG group, while in the high β2-MG group they were only 75.0%, 50.0%, and 25.0%, respectively, which were significantly different between the two groups (P<0.05). The difference of 5-year survival between the two groups was significant (64.1% vs 27.8%, P<0.05) and favorable in normal β2-MG group. Conclusion: β2-MG level in serum is an independen prognostic factor in de novo NHL, and the patients with abnormal β2-MG level in serum have a unfavorable prognosis.

OBJECTIVETo investigate the clinical characteristics and prognosis of patients with different subtypes of breast cancer: basaloid, HER-2 and luminal types, and try to find the evidence of individualized treatment for the patients.
METHODS1280 histologically and immunohistochemically proven patients with resectable breast cancer were treated, and the clinical data including characteristics, relapse and survival of the patients with different subtypes of breast cancer were analyzed retrospectively.
RESULTSOf the 1280 breast cancer patients, basaloid, HER-2 and luminal types accounted for 20.9%, 23.2% and 55.9%, respectively. Basaloid type was more likely to be found in younger patients frequently with a family history of breast cancer. HER-2 type usually had a tumor of larger size with more advanced stage disease and more metastatic lymph nodes. Luminal type was likely to occur in aged patients with an earlier stage disease. The recurrence rates in basaloid, HER-2 and luminal types were 25.0%, 27.9% and 11.7%, respectively. Patients with basaloid or HER-2 type were found to have a significantly higher recurrence rate than the patients with luminal type breast cancer (P < 0.001), but no significant difference was observed between the basaloid and HER-2 types. However, patients with basaloid type breast cancer were more likely to develop lung metastasis than HER-2 type (13.4% vs. 7.1%, P = 0.017). Up to December 2006, the 5-year disease-free survival (DFS) rates for patients with basaloid, HER-2 and luminal types were 72.2%, 68.2% and 86.2% (P < 0.001), respectively. The overall 5-yr survival (OS) rates of the three groups were 88.6%, 83.8% and 95.8% (P < 0.001) , respectively. Of the patients with luminal type breast cancer, HER2-negative patients had a higher DFS (86.2% vs 57.0%, P < 0.001) and OS (95.8% vs 87.7%, P = 0.0001) compared with those with HER2-positive. The results of Multivariate Cox Regression showed that tumor size and lymph node state were the most important factors influencing the prognosis.
CONCLUSIONEach subtype of breast cancer has somewhat its own specific clinical features in terms of recurrence pattern and prognosis, therefore, individualized treatment regimen may be required.

Objective: This study was designed to improve complete remission(CR) rate in the patients with advanced lymphoblastic lymphoma by using early extensive induction chemotherapy. Method:A total of 11 cases of untreated lymphoblastic lymphoma in Stage Ⅲ /Ⅳ were received CVDLP regimen, including cytoxan(CTX) 1000 mg/m2 d1, vincristine(VCR) 1.5 mg/m2 d1,d8,d15,d21, Adriamycin(ADR) 40 mg/m2 d1, d2, d21, L-asparaginase(L-ASP) 10000 U/m2 d15~24, Prednison 60 mg/m2 d1~28, gradually decreased dosage at d15. methotrexate+ Ara-C IT qw× 4. Efficacy were evaluated at d28~35. Simultaneously,retrospective analysis for 9 cases of untreated lymphoblastic lymphoma in Stage Ⅲ /Ⅳ treated with 2 cycles of CHOP were made. Efficacy were evaluated at d35. Results: CVDLP group: 10/11 cases of patients achieved CR, and 1/11 case had PR, rate of complete remission was 90.9% ;10/11 cases had Grade Ⅳ hematological toxicity,1/11 cases had Grade Ⅲ hematological toxicity(WHO). CHOP group:3/9 got CR;5/9 got PR;1/9 had MR,rate of complete remission was 33% . 3/9 had Grade Ⅲ hematology toxicity;6/9 had GradeⅡ hematological toxicity. Conclusion:CVDLP regimen can induce higher CR rate than CHOP regimen in untreated lymphoblastic lymphoma with Stage Ⅲ /Ⅳ , but hematology toxicity was also higher than CHOP regimen. However this induction regimen is safe and viable with strengthening supportive care.

OBJECTIVE To evaluate the effect of Guizhi Fuling Capsule active pharmaceutical ingredient (API) and its fractions on human breast cancer cells proliferation by high-throughput screening assay. METHODS The crude fractions were obtained from the extraction and elution of the API of Guizhi Fuling Capsule, and 929 standard fractions were obtained by the optimal separation conditions. Sulforhodamine B (SRB) method was used to evaluate the effects of the Guizhi Fuling capsule API and 929 kinds of fractions on the proliferation of human breast cancer cells MCF- 7 and MDA- MB- 231. RESULTS The Guizhi Fuling capsule API had a strong ability to inhibit the proliferation of MCF-7 cells at high concentration and the ability to inhibit MDA-MB-231 cells' proliferate at low concentration follow?ing 72 h treatment;some samples of 929 fractions (5 μg·mL-1) was found to have a breast cancer cell growth inhibition rate above 50%, without toxicity on HUVECs proliferation. CONCLUSION The API of Guizhi Fuling capsule had significant cytotoxicity effects on these two human breast cancer cells, with significant concentration- and time-dependent manner.

OBJECTIVETo confirm the therapeutic effect of dendritic cell (DC) vaccine on treatment for mice with lymphoma and the protective effect of DC vaccine loaded with different antigens on the tumor-bearing BAL B/c mice.
METHODSFirstly, a mouse tumor model was set up by s. c. inoculation of 1 x 10(6)/mouse A20 tumor cells. Then different DC vaccines were injected, respectively, and the tumor size and survival time were observed. Secondly, the immunized mice with DC vaccines were challenged with A20 tumor cells, and observed whether a new tumor occurred in the mice and the time of survival.
RESULTSThe tumor of mice immunized with Id-DC vaccines grew slower than the controls (mean time of survival was 40.4 days vs. 33.4 days), but statistically not significantly different. The tumor of mice injected with CPP-Id-DC vaccines grew slower than that injected with Id-DC vaccines and controls, and one of 5 mice got CR and the tumor in another one mouse became stable. The median survival time was 70.8 days during a 90-days observation period. The difference was significant (P<0.01). The mice injected with Id-DC vaccines were challenged with A20 tumor cells showed new tumor occurred at 7 - 12 days, and 1 of the 5 mice survived for 60 days. The mice injected with CPP-Id-DC vaccines had no tumor.
CONCLUSIONThe DC loaded with CPP-Id was better than that loaded with Id alone in treating B cell lymphoma, and It can enhance their antitumor responses and prolong the survival time of the A20 tumor animal models. The vaccine of DC loaded with CPP-Id can protect mice from A20 tumor cell challenge.

OBJECTIVETo investigate the therapeutic effect, long term survival and side effect on NSCLC patients treated with nadaplatin combined with paclitaxol and cisplatin combined with paclitaxol.
METHODSNSCLC patients with stage IIIB or IV were randomized into two groups in this prospective clinical study. TN group: nadaplatin 30 mg/m2 dl-3, paclitaxol 175 mg/m2 dl, repeated every 4 weeks. TP group: DDP 30 mg/m2 dl-3, paclitaxol 175 mg/m2 dl, repeated every 4 weeks.
RESULTSSixty patients were enrolled and 57 were evaluable with 30 in TN group and 27 in TP group. The overall response rate were 43.3% vs. 48.1% (P = 0.716), and the disease control rate were 86.7% vs. 88.8% in TN and TP group (P = 0.799), respectively. The median survival time was 14.3 vs. 13.0 months, and the 1- and 2-year survival rate was 62.5% vs. 59.1%, 0% vs. 5.8% in TN and TP group (P = 0.839), respectively. The rates of neutropenia and thrombocytopenia were similar in TN and TP groups whereas more patients in TP group than in TN group suffered from anemia (38.5% vs. 17.5%, P = 0.001), nausea and vomiting (82.6% vs. 35.6%, P = 0.000), fatigue (35.9% vs. 14.1%, P = 0.000) and peripheral neurotoxicity (50.0% vs. 21.9%, calculated by case, P = 0.023).
CONCLUSIONNadaplatin combined with paclitaxol is an effective treatment regimen for NSCLC patients. When compared with similar regimen with cisplatin, the response rate and survival were similar; however, nadaplatin regimen shows some superiority as regards some treatment side effect.
