Objective To develop a new method to repair the defect after enlarged excision of dermatofibrosarcoma protuberans.Methods This study included 8 patients with dermatofibrosarcoma protuberans measuring 2.5 to 5.5 cm in diameter.All the patients underwent enlarged excision of the affected skin and subcutaneous tissue.The defect measured 12.5 to 17.5 cm in diameter.Sieve skin flaps secured with a vacuum-assisted closure device were used to repair the huge surface defects.Results All the patients experienced the survival of sieve skin flaps at stage Ⅰ after operation,with no infection,effusion or necrosis.No relapse was observed during the 3 to 40 months of follow up.A satisfactory recovery was achieved in skin appearance and function with the formation of a flat scar,and no obvious proliferation occurred.Conclusion The vacuum-assisted closure device offers a safe and simple method for securing skin grafts to the defect after enlarged excision of dermatofibrosarcoma protuberans.

OBJECTIVE:To investigate clinical efficacy of oxaliplatin+calcium folinate+5-fluorouracil(mFOLFOX6),oxalipl-atin+capecitabine(CapeOX),irinotecan+calcium folinate+5-fluorouracil(FOLFIRI)for metastatic colorectal cancer,and to conduct cost-effectiveness analysis. METHODS:48 patients with colorectal cancer were divided into mFOLFOX6 group(30 cases),Cape-OX group(8 cases)and FOLFIRI group(10 cases). Clinical efficacy and ADR of 3 groups were analyzed,and cost-effectiveness analysis was also conducted. RESULTS:Clinical effective rates of mFOLFOX6 group,CapeOX group and FOLFIRI group were 96.67%,87.50% and 80.00%,respectively,the mFOLFX6 group was significantly higher than the other 2 groups,with statistical significance(P<0.05). mFOLFOX6 group had high incidence of gastrointestinal side effects (70.00%). FOLFIRI group had high incidence of myelosuppression (70.00%). CapeOX and mFOLFOX6 group suffered from liver injury possibly,without statistical significance (P>0.05). The C/E of mFOLFOX6 group,CapeOX group and FOLFIRI group were 11 950,15 674 and 18 397 re-spectively,to which results of sensitivity analysis were same. CONCLUSIONS:The cost-effectiveness of mFOLFOX6 regimen is superior to CapeOX and FOLFIRI regimen in the treatment of metastatic colorectal cancer,but it has the high incidence of gastroin-testinal side effects.

OBJECTIVETo observe the clinical effect of Ziyin Huoxue Granule (ZHG) combined glucocorticoids and antibiotics in treatment of radiation pneumonitis.

METHODSTotally 70 radiation pneumonitis patients were assigned to the treatment group and the control group according to random digit table, 35 in each group. All patients received glucocorticoids and antibiotics. Patients in the treatment group additionally took ZHG, one dose per day for 4 successive weeks. Watters clinical-radiologic-physiologic (CRP) score, Karnofsky Performance Status Scale (KPS) , and acute radiation injury classification [set by Radiation Therapy Oncology Group (RTOG)] were observed in the two groups before and after treatment. The application time for antibiotics and glucocorticoids was compared between the two groups.

RESULTSAll patients completed this trial, and nobody dropped out or died. There was no statistical difference in Watters-CRP scores, KPS, or RTOG between the two groups before treatment (P > 0.05). Compared with before treatment in the same group, RTOG classification was obviously improved in the two groups (P < 0.05). Compared with the control group, Watters-CRP scores decreased, KPS increased, the application time for antibiotics and glucocorticoids was reduced (P < 0.05). The efficacy of RTOG classification was better in the treatment group than in the control group, but with no statistical difference between the two groups (P > 0.05).

CONCLUSIONZHG combined glucocorticoids and antibiotics was superior in treating radiation pneumonitis to using glucocorticoids or antibiotics alone in elevating Watters-CRP scores, shortening the application time for glucocorticoids and antibiotics, and improving patients' physical conditions.

Objective To observe differences between repeat and written response in speech recognition tests of short Mandarin monosyllable lists. Methods 12 normal-hearing subjects were tested by 6 short monosyllabic lists. The subjects should repeat and write down.the contents of the tests at the same time, the tester monitors au-rally and records the subjects' reactions. The speech recognition scoring error under different responses at different presentation levels could be obtained by comparing the records of the subjects with the tester. Results The speech recognition scoring of repeat and written response were highly correlated with each other (P<0.01). However, 19(26.4%) out of 72 pairs of test records were inconsistent. The error range of them was from -5% to 10%. When the presentation level was 5 dB HL, the difference among the speech recognition scoring was significant statistically, but not significant when the presentation level at 20, 15, 10 and 0 dB HL. Conclusion The test results of speech audiometry are impacted by different respond methods. In the open-set test, it's supposed that the subjects should make notes while repeating the contents of the tests, then compare with the aural monitoring records of the tester to keep the reliability of the test.

Objective To explore the function of fluorescent probe JC-1 in detecting the changes of mitochondrial membrane potential(△?m)in early apoptotic cells.Methods After 2-ME was used to induce MUTZ-1 cell apoptosis,cells were dyed with fluorescent probe JC-1,and then the changes of △?m in the early stage of apoptotic cells were analyzed by flow cytometry or detected under fluorescent microscope. Results The control cells with high △?m are those forming JC-1 aggregates in the inner membrane of mitochondria,thus showing orange-red fluorescence.2-ME caused decrease of △?m in MUTZ-1 cells,in which JC-1 maintains monomeric form,thus showing only green fluorescence.The decreases of △?m were in a time-dependent manner,which were significantly higher than those in control group(P

AIM:To construct adenovirus vector expressing mice B7-H1 gene, transfect dendritic cells ( DCs ) , and to study the therapeutic effect of modified DC on thyroid-associated ophthalmopathy ( TAO) in mice.
METHODS: We designed and constructed B7-H1 gene adenovirus expression vector, and transfected DCs from mouse bone marrow, tested the phenotype and function of modified DCs, identificated its negative regulation to immune responses. The modified DCs were infected the sicked mice. And then the immunotherapeutic effect of modified DCs to TAO were tested.
RESULTS: B7 - H1 gene adenovirus vector was constructed and transfected DCs from bone marrow. The titer of the recombinant adenovirus was 1. 8í109 PFU/mL. B7-H1 gene modified DCs characteristics of regulatory DCs, could inhibit positive immune responses. The inhibition proceeding of TAO into mice infected modified DCs, was obviously prior to the control mice. The gene modified DCs, maybe become the new immunotherapy biological agent to thy TAO.
CONCLUSION: We constructed the expression of mouse B7 - H1 gene adenovirus expressed vector successfully, transfected DCs, by vector have properties of regulatory DCs, inhibiting positive immune response and the occurrence and development of thyroid eye disease. Gene modified DCs, reveal potent to the treatment of thyroid eye disease.

OBJECTIVETo observe the effects of H. dulcis on relieving alcohol toxicity by animal experiments.

METHODMale kunming mice were ovraiectomized and randomly divided into 5 groups: control group, model group, and aqueous extracts of H. dulcis group at 0.5, 0.25, 0.125 g x mL(-1). The acute alcohlism animals induced by gastral administration with "Er Guo Tou" and the alchol concentrations in serum were detected after treated with the extracts within 0.5-3 h by biochemical enzymes.

RESULTThe alcohol concentration in blood was up to the maximum in 0.5-1.5 h. However, the alcohol concentrations in blood of aqueous extract from H. dulcis group were decreased in 0.5-3 h. The activity of ADH in the liver in aqueous extract of H. dulcis group was increased in 2-3 h, while it was significantly increased in 1-1.5 h (P <0.05).

CONCLUSIONThe aqueous extract of H. dulcis could reduce the alchol concentration in blood of animals and inrease the activity of ADH after given alcohol. It means the extract has the effect of relieving alcohol toxicity and preventing drunkenness through restraining the absorption of alcohol in the gastrointestinal tract and promoting the metabolism of alcohol in the liver.
