1.Advances in molecular targeted therapy and biochemotherapy in oncology
Chinese Journal of Cancer Biotherapy 1995;0(02):-
Biochemotherapy refers to the combination of biotherapy and chemotherapy,and it has been rapidly developed since its emergence.Biochemotherapy has brought both new therapies and new therapeutic ideas for the treatment of malignant tumors.In this article,we reviewed the recent advances in tumor biochemotherapies,including expansion of the indications,retaining of therapy even when tumor progressed(unique to biochemotherapy),and reversal of chemotherapy resistance by targeted therapy,the predicting response to tumor biochemotherapy,recent clinical trials of immunotherapy-based chemotherapy,and evaluation criteria for assessment of biochemotherapy response,and so on.

OBJECTIVE:To establish a method for simultaneous determination of notoginsenoside R1,ginsenoside Rg1 and gin-senoside Rb1 in Shenqi xinshu capsule. METHODS:HPLC was performed on the column of Zorbax SB-C18(150 × 4.6 mm,5 μm) with mobile phase of acetonitrile-water at a flow rate of 1.0 ml/min,detection wavelength was 203 nm,column temperature was 30℃,and the injection volume was 10 μl. RESULTS:The linear range was 0.199 8-3.996 0 μg for notoginsenoside R1,0.842 8-10.143 0 μg for ginsenoside Rg1 and 0.823 4-9.978 0 μg for ginsenoside Rb1;RSDs of precision,stability and reproducibility tests were low-er than 2%;recoveries were 95.17%-100.17%(RSD=1.81%,n=9),97.32%-101.18%(RSD=1.44%,n=9)and 95.22%-98.89%(RSD=1.22%,n=9). CONCLUSIONS:The method is simple,accurate and reproducible,and can be used for the simultaneous contents determination of notoginsenoside R1,ginsenoside Rg1 and ginsenoside Rb1 in Shenqi xinshu capsule.

Objective To observe and compare the anti-angiogenic effect of sorafenib, unfractionated heparin(UFH)and low molecular weight heparin (LMWH), singly used or in combination, with chick chorioallantoic membrane assay. Methods Sixty 8d-developed chick embryos were randomly divided into 6 groups (10 each): control group, sorafenib group, UFH group, LMWH group, sorafenib+UFH group, and sorafenib+LMWH group. Drugs were given respectively and incubation continued. The dosage of drugs for each embryo was 20 nmol of sorafenib, 5U of UFH and 5U of LMWH, respectively, and H-DMEM was applied to the embryo in control group in the same volume (2?l). After continuing incubation for another 72h, the anti-angiogenic effect in each group was observed and the vascular number in the chick chorioallantoic membrane was counted. Results Vascular number in single drug groups (sorafenib group: 8.9?1.9; UFH group: 7.6?2.3; LMWH group: 6.9?1.3) was significantly smaller than that in the control group (26.8?2.3, P

Objective To compare the therapeutic effects of early enteral nutrition and delayed enteral nutrition on severe acute pancreatitis. Methods Sixty-four patients of severe acute pancreatitis were enrolled into two groups: early enteral nutrition group was used as the treatment group and delayed enteral nutrition was used as the control group. Two weeks after the treatment, Variables of TP, ALB, CRP, APACHEⅡscore, hospital stay and recovery time of blood and urine amylase were compared between the two groups. Results The TP and ALB of the treatment group were significantly higher than those in the control group (P<0.05). The CRP and APACHEⅡscore of the treatment group were significantly lower than those in the control group (P<0.05). Compared with the control group, the recovery time of blood amylase, urine amylase and hospital stay were significantly shorter in the treatment group (P<0.05). Conclusion Using early enteral nutrition treatment in patients with severe acute pancreatitis is efficient, worthy of clinical use.

OBJECTIVE: To investigate the improvement effects of Qishenlian eczema cream on the atopic dermatitis (AD) model guinea pigs, and to investigate its possible mechanism. METHODS: Female guinea pigs were randomly divided into normal control group, model control group, matrix control group (Qishenlian eczema cream matrix, 1 g/kg), Qishenlian eczema cream low-dose, medium-dose and high-dose groups (0.5, 1, 2 g/kg) and Hydrocortisone butyrate cream group (0.5 g/kg), with 10 guinea pigs in each group. Using ovalbumin as antigen, the skin allergy of guinea pigs was stimulated to induce AD model. Forty-eight hours after the last excitation, guinea pigs were smeared with normal saline in normal control group and model control group, while those were smeared with Qishenlian eczema cream matrix in matrix control group, and administration groups were treated with relevant medicine, twice a day, for consecutive 14 d. The scores of erythema, edema and scratch before and after administration were recorded in each group. The morphological characteristics of skin were observed by HE staining. TUNEL method was used to detect the apoptosis of keratinocytes in skin tissue. The level of IFN-γ in skin lesions was detected by ELISA. RESULTS: Compared with normal control group, inflammatory cell infiltration, hyperkeratosis of epidermis and thickening of spinous layer were observed in skin tissue of guinea pigs in model control group and matrix control group; the scores of erythema, edema and scratch and their total score, the level of IFN-γ in skin tissue were increased significantly; the apoptosis number of keratinocytes was decreased significantly (P<0.01). Compared with model control group and matrix control group, above symptoms of medication groups were relieved to different extents; the scores of erythema, edema and scratch and their total score after medication in medication groups, the level of IFN-γ in skin tissue in Qishenlian eczema cream medium-dose and high-dose groups and Hydrocortisone butyrate cream group were decreased significantly, and above scores in medication groups were significantly lower than before medication (P<0.05 or P<0.01); the apoptosis number of keratinocytes was increased significantly in medication groups (P<0.05 or P<0.01). CONCLUSIONS: Qishenlian eczema cream has certain improvement effect on AD model guinea pigs, the mechanism of which may be associated with promoting the keratinocyte apoptosis, reducing the level of INF-γ in skin tissue.
