Fu-Zheng Pei-Ben therapy, as a major therapeutic principle, has become the main guiding thought of cancer therapy currently. Through the traditional Chinese medicine (TCM) history, Fu-Zheng Pei-Ben thera-py is one of the most important therapies . As early as the Spring and Autumn Period , the importance of vital qi has been recorded in the Huang-Di Nei-Jing. After that, TCM doctors have enriched the connotation and extension of the Fu-Zhe ng therapy . Until modern times , Professor Liu Jiaxiang applied Fu-Zhe ng therapy to the treatment of cancer . This paper explained the sources of Fu-Zhe ng cancer therapy through the analy-sis of its history in order to provide a reference to deepen the theoretical studies in the diagnosis and treat-ment of cancer in the future .

Background and purpose:Epirubicin is one of the fi rst line chemotherapy drugs in the treatment of breast cancer, and liposome doxorubicin is a new antitumor drug that has been reported to have less cardiotoxicity and myelosuppression compared to free doxorubicin. Dentritic cells (DC) play important roles in tumor immunity. Our experiment investigated the impacts of epirubicin and liposome doxorubicin on different human breast cancer cell lines and dentritic cells, and evaluated their roles in the treatment of breast cancer. Methods:Human breast cancer cell lines, Bcap37 and MDA-MB-231, along with human dentritic cells isolated and induced into maturation, were cultured with epirubicin and liposome adriamycin at different concentrations (0, 0.25, 0.5, 1.0, 2.0, 4.0, 10.0 ?g/ml), respectively. The inhibitory effects were detected by MTT method after 24, 48, 72 h. Results:Epirubicin and liposome adriamycin could inhibit the proliferation of Bcap37 cells, MDA-MB-231 cells, and human dentritic cells. Liposome adriamycin exhibited a lighter inhibition on dentritic cells than on human breast cancer cell lines (Bcap37 and MDA- MB-231) (F=22.208, P

BackgroundLaser peripheral iridotomy(LPI) can break the pupillary block,and is an effective method of treating acute primary angle closure (APAC).However,a part of APAC eyes may gradually develop a formation and extension of peripheral anterior synechia(PAS) and increased intraocular pressure(IOP) after LPI.ObjectiveTo investigate the relationship between appositional angle closure and darkroom provocative test(DRPT) in the fellow eyes with APAC after LPI.Methods Fellow eyes of APAC without PAS after LPI were studied.Ultrasounic biomicroscopy(UBM) were performed in darkness to observe whether appositional angle closure occurred and compare the relationship between the quadrants with appositional angle closure and the results of DRPT.Results Fifty-four patients were included in the study.Appositional angle closure was observed in at least one quadrant in 20(37.0％ ) of the 54 fellow eyes with APAC after LPI.Fifty-one patients were given DRPT and positive result in 9 patients( 17.6％ ).According to the quadrants with appositional angle closure,there were 5 patients with DRPT positive results in 46 patients with appositional angle closure 0 to 2 quadrants,and 4 patients with DRPT positive results in 5 patients with appositional angle closure 3 to 4 quadrants ( P =0.003 ).Bivariate correlation analysis indicated a positive correlation between the value of the increased IOP in DRPT and the number of quadrants with appositional angle closure in darkness( r =0.397,P =0.004).ConclusionsA certain proportional fellow eyes of APAC appeared appositional angle closure in darkness and DRPT positive result after LPI.The more the quadrants of appositional angle closure after LPI,the greater the likelihood of a positive DRPT.It suggests that the APAC fellow eyes and attack eyes with the same anatomical configuration still have the possibility of angle closure after LPI,and need follow-up and treatment for a long time.

Background The scarring of conjunctival filtering blebs after glaucomatous surgery is a leading cause of operation failure.Exploring the balance between matrix metalloproteinase-2 (MMP-2) and tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) in conjunctival filtering bleb is very important for the study on pathogenesis of postoperative scarring.Objective This study was to evaluate the role of MMP-2 and TIMP-2 in wounding healing of subconjunctival tissue after filtering surgery in rats.Methods Sixty-three clean male SD rats were divided into normal control group and postoperative 1-day,3-day,5-day,7-day,14-day and 28-day group.The drainage tube was monocularly implanted into the anterior chamber of the rats to establish the filtering surgery models,and the operative response of the eyes was examined under the slit lamp microscope.The animals were sacrificed in corresponding time points,and the frozen sections of eyeballs were prepared,and the expressions of MMP-2 and TIMP-2 in conjunctival and subconjunctival tissues were detected using immunofluorescence technique.Western blot was employed to assay the dynamic expressions of MMP-2 and TIMP-2 proteins in conjunctival and subconjunctival tissues in different groups.The use and care of the rats complied with the Instruction Notions with Respect to Care for Laboratory by State Ministry of Science and Technology.Results Filtering blebs were formed in all the operated eyes 1 day after surgery and remained for 7-17 days,with the average survival time of 12 days.Western blot assay revealed that the expression levels of MMP-2 protein in the filtering blebs of the normal control group were 121.67 ±4.37,and the expressions were gradually elevated from the postoperative 3-day group (183.67±5.61) until the postoperative 7-day group (230.50±8.48) and then gradually declined till the postoperative 28-day group (172.33 ± 8.43),showing a significant difference among the groups (F=280.18,P＜0.05).In addition,the expression levels of TIMP-2 protein in filtering blebs of the normal control group were 102.50 ±6.25.The expression levels were gradually raised in postoperative 3-day group (162.67±7.00) and peaked in the postoperative 5-day group (232.00± 11.03),and then the levels gradually reduced till the postoperative 28-day group (150.50±6.41),with a significant difference among the groups (F =145.34,P ＜ 0.05).Immunofluorescent staining showed that MMP-2 and TIMP-2 were weakly expressed in the conjunctival epithelium of the normal rats,while in the operated rats,strong fluorescence for MMP-2 and TIMP-2 was seen in both conjunctival epithelium and subconjunctival tissues of filtering blebs.Conclusions The expression trends of MMP-2 and TIMP-2 in the filtering blebs are consistent to the fibrosis process of conjunctival tissue,indicating that MMP-2 and TIMP-2 participate in the scar formation of conjunctival filtering bleb after glaucoma filtering surgery.

Background Human retinal pigment epithelial (RPE) cell transplantation treating retinal degenerative diseases is a researching topic,and the source of human RPE cells is a key problem.Many biological carriers can be used for the preparation of RPE cell layer.However,some advantages,such as cytotoxicity,lack of stability and immunologic reaction etc.are still existed.To study an ideal biological carrier is very important.Objective This experimental was to determine the effects of amniotic membrane on the proliferation and differentiation of human RPE cells and the possibility as a scaffold for RPE cell transplantation.Methods ARPE19 cell line cells were cultured and passaged in DMEM/F12 medium with 10％ fetal bovine serum,and 8-12generation of cells were used.The cells were divided into two groups.One group of cells were incubated on the denuded amniotic membrane,and the other group of cells were cultured in the medium (control group).MTT was performed to detect the A492 value of RPE cells for the evaluation of cell proliferation ability 24,48,72,96 hours after culture.Cell morphology was compared by histopathological examination 3 weeks after culture.The mRNA expression of pigment epithelium-derived factor (PEDF),N-cadherin,β-catenin and cell connection related proteins in the cells of both groups were assayed using reverse transcription polymerase chain reaction (RT-PCR).Ultrastructure of the cells was observed under the transmission and scan electronic microscope 3 weeks after culture.Results The number of ARPE-19 cells cultured on denuded amniotic membrane was decreased significantly in comparison with the normal culture plate(F=41.760,P =0.000).Histopatholy also showed that the cell density on amniotic membrane was lower than of normal cells on plate surface.Moreover,the expression level of claudin 1 mRNA,N-cadherin mRNA and PEDF mRNA were significantly up-regulated in denuded amniotic membrane group in comparison with control group (t=15.828,P=0.000 ;t=6.839,P=0.002 ;t=14.667,P=0.000),but the expression of Connexin 43 mRNA was down-regulated in denuded amniotic membrane group compared with control group(t=3.358,P=0.024).Ultrastructural examination revealed that ARPE-19 cells cultured on amniotic membrane exhibited a polygonal epithelial phenotype with cilium on the apical side,however,the cells cultured on normal culture plate displayed fusiform shape and uneven thickness.Conclusions Amniotic membrane plays a promoting effect on the differentiation of ARPE-19 cells and a inhibitory effect on the proliferation of ARPE-19 cells,suggesting that amniotic membrane might be an useful scaffold for the preparation of functionally mature RPE cells for clinical transplantation.

Objective:To evaluate the effects of nutrition supplemented with glutamine on immune function and systemic inflammatory response in patients with severe craniocerebral trauma.Methods: Forty postoperative patients with severe craniocerebral trauma were randomized into experiment group(n=20) and control group(n=20).All patients received similar nitrogen and calorie for one week.Patients in experiment group were additionally supplemented with glutamine at dose of 0.50 g/(kg?d).Blood samples were obtained for measurement of IgM,IgG,IgA,CD3,CD4,CD8,CD4/CD8 before and after nutrition support the systemic inflammatory response syndrome(SIRS)was observed daily,and the serum albumin,transferin,hemoglobin and GCS were detected before and after nutrition support.Results: IgG,IgA,CD4,CD4/CD8,GCS and transferin in experiment group increased significantly after nutrition than in control group.Conclusion: Nutrition supplemented with glutamine may improve immune function,GCS and transferin in patients with severe cranial trauma.

BACKGROUND: The neurons in the medial septum (MS), vertical and horizontal limbs of diagonal band of Broca (vDB and hDB) in the basal forebrain contain rich androgen receptors (ARs) and estrogen receptors (ERs) by which androgen and estrogen can act dramatically on the neurons in the basal forebrain, subsequently affecting learning and memory processes.OBJECTIVE: To qualitatively and quantitatively investigate the effects of androgen replacement therapy on the nitric oxide synthase (NOS)-positive and nestin-positive neurons in the MS, vDB and hDB of castrated adult male rats.DESIGN: A randomly controlled study on experimental animals.SETTING: Department of Anatomy and Brain Research Laboratory of Zhngshan Medical College of Sun Yat-sen University.MATERIALS: The experiment was performed at Department of Anatomy and Brain Research Laboratory of Zhongshan Medical College of Sun Yatsen University from June 2001 to June 2002. Totally twenty-eight adult male Sprague-Dawley rats were randomly divided into four groups with seven rats in each group: androgen replacement therapy for 4 weeks following 24 hours of castration (ART1), androgen replacement therapy for 2 weeks following 2 weeks of castration (ART2), vehicle replacement therapy for 4weeks following 24 hours of castration (VRT), sham-operated group (Sham).INTERVENTIONS: ① ART1 group: The castrated rats received subcutaneous injection of testosterone proprionate (25 mg/kg) dissolved in 100 μL of sterile sesame oil every other day from 10:30 am to 11:00 am for 14 times (4 weeks). ② ART2 group: The castrated rats received subcutaneous injection of testosterone proprionate with the same dosage and method as ART1 group for 7 times (2 weeks). ③ The rats in VRT group received subcutaneous injection of 100μL of sterile sesame oil for 14 times (4 weeks) by the same regime as described above. ④ Rats in Sham group only received sham-operated treatments, and testes were intact and lived for 4 weeks.MAIN OUTCOME MEASURES: Morphology and counts of NOS-positive and nestin-positive neurons were observed in the MS, vDB and hDB with immunohistochemical method at various time points.RESULTS: Data of totally 28 rats were involved in the final analyses. ①Morphological features of both NOS-positive and nestin-positive neurons in the MS, vDB and hDB were not significantly changed among four groups. ② The number of NOS-positive and nestin-positive neurons in the MS and vDB of VRT group were significantly higher than those of Sham group (P＜ 0.05 or 0.01), whereas the numbers of the NOS-positive and nestin-posi-tive neurons in the MS and vDB of ART1 and ART2 groups was significantly lower than those of VRT group (P ＜ 0.05 or 0.01), which nearly reached the levels of sham group (P ＞ 0.05).CONCLUSION: Androgen replacement therapy produces no significant effects on the morphological features of NOS-positive and nestin-positive neurons, but the therapy can selectively decrease the numbers of NOS-positive and nestin-positive neurons in different subregions of the basal forebrain, which may be closely related to androgen downregulation of expressions of NOS and nestin by ARs-mediated mechanisms, thereby producing complex effects on learning and memory processes.

Our laboratory isolated three defensin molecules from the circulating neutrophils of healthydonors.The three molecule mixture was conjugated with BSA and immunized New Zealand rab-bit.ELISA showed that the rabbit antisera was of a very high titters,which were specific for hu-man defensins.Immunoperoxidase staining with this rabbit antisera indicated that normal humanneutrophils,acute myeloid leukemia cell lines KG1 and HL-60 were highly positive.In con-trast,normal mononuclear leukocytes,erythrocytes,erythroleukemia cell line K562 were all neg-ative,even rabbit and guinea pig neutrophils had no response to this rabbit anti-human de-fensins antisera.Our preliminary experiments suggested that the rabbit antisera was highly spe-cific for human defensins.Probably,defensin is a differentiation antigen of granunocyte lineage,and antibody against human defensins would be a candidate immunological reagent specific for a-cute myeloid leukemia.Further work for this should be done.
