Objective To investigate the variations of intestinal flora of common carp in patients with hyperuricemia in Qingdao District.Methods The fecal flora was analyzed by gradient dilution method.The levels of uric acid in blood and feces were detected by enzyme colorimetry method and phosphortungstic acid method,respectively.Results E.coli (7.58 ± 0.34,P < 0.05),the total count of aerobian (7.76 ± 0.67,P < 0.05),and bacteroides (2.75 ± 0.31,P < 0.05) were significantly increased in hyperuricemia patients compared to controls.Bifidobacterium (5.38 ± 0.34,P < 0.05) and lactobacillus (2.69 ± 1.48,P < 0.05) were sig-nificantly decreased compared to controls.Concentrations of uric acid in blood and feces were both significantly higher in the patients relative to healthy controls.Decomposition capability was similar to healthy controls.Decomposition capability of uric acid revealed a close correlation with bifidobacterium and lactobacillus,respectively (r =0.565,0.328,P < 0.05).Conclusions Intestinal dysbacteriosis was found by the analysis of fecal flora in patient with hyperuricemia in Qingdao district.Dysbacteriosis might participate in the process of hyperuricemia onset.

Objective: To investigate a better method to correct the secondary nasal deformity of postoperative cleft lip, by using the expanded polytetrafluoroethylene (ePTFE) to reinforce the intensity of the nasal alar cartilage. Methods: ePTFE was used to reinforce the intensity of the cleft side of nasal alar cartilage and corrected 120 cases of the secondary nasal deformities of postoperative cleft lip. Results: All the 120 cases of patients with nasal alar tumbling showed significant improvements. In follow-up, 76 cases of patients' wound healed well. No rejection in all cases. Conclusion: The ePTFE is an ideal implant material to correct the secondary nasal deformities of postoperative cleft lip.

Objective To evaluate the relationship between neoadjuvant chemotherapy (combination of taxanes and anthracyclines ) induced-neutropenia and the efficacy of neoadjuvant chemotherapy and long-term survival in operable breast cancer patients. Methods Two hundred and eleven patients received 4 cycles of neoadjuvant chemotherapy (combination of taxanes and anthracyclines).Clinicopathological characteristics were compared between patients with neoadjuvant chemotherapy-induced neutropenia and patients without neutropenia. The efficacy of neoadjuvant chemotheray and long-term survival rate were analyzed. Results Among 211 patients there were 51 (24. 2% ) cases suffering from neutropenia and 160 (75.8%) cases were of no-neutropenia. The response to chemotherapy in patients with neutropenia were more effective than in no- neutropenia ones ( P < 0. 05 ). The 5-year disease-free survival (DFS) in patients with neutropenia was 82. 4%, while the 5-year disease-free survival ( DFS) with nonneutropenia was 60% ( P < 0. 01 ). Additionally, the 5-year overall survival ( OS ) in patients with neutropenia was 90. 2% and in patients with non-neutropenia patients was 67. 5% ( P < 0. 01 ).Conclusions Chemotherapy-induced neutropenia during neoadjuvant chemotherapy combination of taxanes and anthracyclines in patients with operable breast cancer has a better prognosis. The sensitivity of tumors given to chemotherapeutic drugs could be evaluated by chemotherapy-induced neutropenia.

Objective To investigate the effect and mechanism of transplantation of marrow multi- function stem ceils in treating femoral head necrosis.Methods Sixty japanese rabbits were divided into A,B and C groups randomly.After creation of the models of hormone induced necrosis of femoral head;A group was designated as the treatment,B as the control and C as the normal groups.The bone marrow of A group was extracted and isolated and then injected into the left femoral head and the right femoral head was decompressed by drilling only.The rabbits were killed at 8 weeks after the treatment and changes in various parameters were observed,including imaging data of molybdenum target films,CT and MRI;routine pathology with HE staining and ultrastructural alteration by election microscopy.Results Eight weeks after the treatment of transplantation of marrow multifunction stem cells,the X-ray showed only a little change but the typical appearances were revealed by CT and MRI.Pathohistologic manifestation demonstrated decrease of empty bone lacuna,increase of osteoblast and new bone formation.Election microscopy displayed abundant organelles in osteoblasts with few empty bone lacuna,in addition the tansplantation of marrow multifunction stem cells could obtain better reconstraction for the involved femoral head.Conclusions The treatment of transplantation of marrow muhifunction stem cells in femoral head necrosis could accelerate the process of repairing,worthy to be acknowledged as a good and valuable management in rabbits.(J Intervent Radial,2007,16:122-126)

Objective To explore the protective effcets of Schisandra chinensis extract (SCE) in paraquat (PQ)-induced pulmonary fibrosis in mice ,and its intrinsic molecular mechanisms thereof. Methods A total of 108 mice were randomly allocated into six groups (n=18):control group, model group, low concentration of SCE group (200 mg/kg), medium concentration of SCE group (400 mg/kg), high concentration of SCE group (800 mg/kg) and vitamin C group (100 mg/kg). Except control group, mice were given by intragastric administration with PQ (100 mg/kg) and administered with SCE and Vitamin C once per 24 h after PQ modeling. Mice were sacrificed at 7, 14 and 21 d after modeling. Six mice were executed at different time points. The degree of lung tissue inflammation and fibrosis were observed by HE staining and Masson staining. The mRNA and protein expression levels of transforming growth (TGF)-β1, interleukin (IL)-6 and IL-17 in lung tissue were determined by RT-PCR and ELISA respectively. Results (1) Compared with control group, the lung tissue of model group showed a large number of inflammatory cell infiltration, space congestion, and its inflammation scores increased at 7 and 14 days after modeling (P<0.05). At the same time, compared with model group and vitamin C group, inflammation scores were significantly decreased in medium concentration of SCE group and high concentration of SCE group (P<0.05). (2) Compared with control group, collagen fibers and the degree of fibrosis were significantly increased in model group ,while pulmonary fibrosis were decreased in medium concentration of SCE group and high concentration of SCE group at 14 and 21 days after modeling (P<0.05). (3) With the extension of modeling time, both mRNA and protein expressions of TGF-β1 were obviously elevated, IL-6 decreased and IL-17 reduced after the first increase in PQ group. Compared with PQ group, levels of three cytokines mRNA and protein expression in medium concentration of SCE group and high concentration of SCE group changed as follows:IL-6 level was markedly decreased at 7 and 14 days after modeling;TGF-β1 level was markedly increased at 14 and 21 days after modeling. However, IL-17 level was markedly decrease at three time points(P<0.05). Conclusion SCE can relieve PQ-induced lung inflammation and fibrosis by suppressing TGF-β1, IL-6, and IL-17 expressions.

Age - related macular degeneration ( AMD ) is the leading cause of irreversible visual loss in elderly people among white - dominated population. At percent, treatment for AMD includes anti - vascular endothelial growth factor antibody ( Anti- VEGF ) drug treatment, photodynamic therapy ( PDT ) , topical application of triamcinolone acetonide ( TA ) and laser therapy ( nanosecond laser) etc. Through comparative analysis of different treatment methods of AMD, we review the mechanism, clinical efficacy, adverse events and cost effectiveness to provide the basis for clinical treatment.
