BACKGROUND: The application of biological response modifiers (BRMs) has become the fourth cancer treatment following surgery, chemotherapy and radiotherapy. Polysaccharide-peptide (PSP) is a biological response modifier substance playing a special role in cancer treatment, which has been used in the treatment of gastric cancer, lung cancer, esophagual can cer, etc. With good results. OBJECTIVE: To observe the effect of PSP on the immune function and quality of life (QOL) in patients receiving chemotherapy for gynecological malignancies. DESIGN: A comparative observation. SETTING: Department of Obstetrics and Gynecology, Shanghai Jiaotong University Affiliated First People's Hospital. PARTICIPANTS: Forty patients who had been operated on for gyneco logical malignancies were selected from the Department of Obstetrics and Gynecology, Shanghai Jiaotong University Affiliated First People's Hospital from June 1999 to December 2002, including 36 cases of ovarian cancer with an average age of 52 years and 4 cases of endometrial cancer with an average age of 54 years. Patients with ovarian or endometrial cancer suffered from no contraindication in chemotherapy postoperatively were enrolled, otherwise were excluded.METHODS: The 40 patients were divided into study group (n=20) and control group (n=20) by matching according to stage and age. In the study group, the patients were treated with PSP capsules in addition to chemotherapy, whereas those in the control group were treated with chemotherapy only. PAC (phenacetin, spirin, caffeine) and MFP (melphalan, 5-fluorouracil, medroxyprogesterone acetate) regimens were adopted for the ovarian cancers and endometrial cancer respectively. The experiment lasted for two months from the beginning of the second course of chemotherapy to the beginning of the fourth one.MAIN OUTCOME MEASURES: The indexes of blood immune function and QOL were observed before and after treatment.RESULTS: All the 40 patients were involved in the analysis of results. ①The average Karnofkky's scores before and after treatment were (84±9.6)and (90±8.6) in the study group (P ＜ 0.05), and (83±9.2), (80±12.8) in the control group (P ＞ 0.05). The average Karnofkky's score was 10 credits higher in the study group than in the control group (P ＜ 0.05). ② The CD4+,CD4+/CD8+ and natural killer cells after treatment in the study group were all obviously higher than those in the control group (28.14±4.10, 0.96±0.17,23.80±4.90; 23.12±3.97, 0.75±0.21, 5.32±3.90) (P ＜ 0.05, 0.01).CONCLUSION: PSP can improve the cellular immunity and QOL of patients with ovarian or endometrial cancers.

[Objective] To examine the specific gene and protein expression of primary and passaged chondrocytes in normal oxygen tension and hypoxia.[Methods]Articular chondrocytes were isolated from limb joint cartilage of C57BL/6 mice(3~5 days).Primary chondrocytes(P0)and passaled chondrocytes(P1,P2)were cultured in normal oxygen tension and hypoxia respectively for two days.The mRNA levels of collagen II,aggrecan,sox9,Indian hedgehog(ihh),parathyroid hormone-related protein(PTHrP),bone morphogenetic protein(BMP)-4 and wnt5a were examined with RT-PCR,and protein levels of collagen II,aggrecan were examined with immunohistochemistry and toluidine blue staining.[Results]During the culture of primary chondrocyte,the expression of collagen II and aggrecan increased under hypoxia,mRNA levels of collagen II,wnt5a increased and ihh decreased at the same time.The mRNA levels of special genes and differentiation related genes of passaged chondrocytes were not altered under hypoxia.[Conclusion]Protein and mRNA level of Collagen II of primary chondrocyte under hypoxia increased.It may be regulated by chondrocyte differentiation gene ihh,and wnt5a.The chondrocyte phenotype could not be resumed under hypoxia through short-term monolayer culture in vitro.
