OBJECTIVE:To establish an HPLC method for the content determination of oxaliplatin in Oxaliplatin liposome. METHODS:The separation was performed on Hypersil C18(250 mm?4.6 mm,5 ?m) column with methanol-water(5 ∶ 95,V/V) as mobile phase at flow rate of 1.0 mL?min-1. The detection wavelength was set at 250 nm and column temperature was 30 ℃. RESULTS:The linear range of oxaliplatin was 12.2~122.0 ?g.mL-1(n=5,r=0.999 9) with an average recovery of 98.58%(RSD=1.83%). The limit of detection(LOD) was 97.6 ng?mL-1. CONCLUSION:The method is simple,sensitive and accurate for the content determination of oxaliplatin in Oxaliplatin liposome.

Objective To introduce a method of dorsal augmentation rhinoplasty using autogenous septal cartilage. Methods Autogenous septal cartilage was obtained through a standard septoplasty approach. Graft was cut into single oval, or divided into two or three parts, then the cartilage was sutured by means of a mattress suture; or graft was made into an inverted V frame, depending on size and shape of dorsal depression, and finally graft was inserted for augmentation of dorsum. Results Since May 1989 to Dec. 2001, this technique was performed in 43 patients, 6 men and 37 women, with a range of 17-35 years and a mean age of 24 years. Follow-up ranged from 6 months to 5 years. The authors asserted the sustained satisfactory outcomes. Conclusion Autogenous septal graft is technically simple and relatively free of complication. Long-term evaluations show no absorption of grafts and preservation of desired shape.

Objective To introduce a new method of recombinative repair for the old malunion of the fracture of nasal bone. Methods Since 1996.5 to 2001.12, this technique was performed in 28 patients, 23 men and 5 women, with a range of 18~45 years, a mean age of 29 years. The nasal skin was protected with a rubber pad, and malformed nasal bones were beat out with a small hammer, so as to create a new refracture, then manual reduction was performed with finger and the septal periosted elevator. Results Follow-up ranged from 3 months to 5 years. Of all the patients, 23 cases were cured, 5 cases improved, and the overall effective rate was 100 %. Most of them were satisfied with the successful operation. Conclusion The operative procedure of recombinative repair is technically simple and easy, and the patients suffer little. It is an update and efficacious therapeutic method.

Objective To investigate the mRNA,protein expression and tyrosine phosphorylation of insulin receptor substrate.1(IRS-1)in endometrial carcinoma.Methods Sixty-three endometrial carcinoma(EC)patients,21 endometrial atypical hyperplasia(AHE)patients and 22 normal control(NE) entered this smdy.Their clinical information were colleeted Fasting serum C-peptide concentration was measured.Expression of IRS-1 in endometrium was examined by RT-PCR and western blol Immunoprecipitation was used to measure the tyrosine phosphorylation of IRS-1.Results C-peptide 0.007].There were no significant differences in IRS-l mRNA and protein expression among the three grouDs.Tyrosine phosphorylation of IRS-1 in EC group[(62±36)%]was higher than that in AHE and NE groups[(53 4-34)%and(35 4-33)%;P=0.048,0.002].IRS-1 activation in AHE group was also higher than nornlal control(P=0.045).IRs-1 activation in endometrioid carcinoma[(69 4-33)%]was higher than that in other histological types[(34±31)%;t=2.300,P=0.025].IRs-l tyrosine phosphorylation was significantly higher in patients with advanced stage,high grade,deep myometrial invasion and pelvic lymph node metastasis.IRS-l activation in endometrium was positively correlated with fasting sertlm C-peptide concentration(r=0.491,P=0.001).Conclusions There is excessive activation of IRS-1 in endometrial carcinoma and atypical hyperplasia.Activation of IRS-I in endometrial carcinoma is related with poor clinical-pathologic fleatures and may be a prognostic predictor for this tumor.Over-activationof IRS-1 may be an intermediate event linking the hyperinsulinemia and endometrial carcinoma.

BACKGROUND: It remains unclear whether proinflammatory factor, such as tumor necrosis factor-α (TNF-α), γ-interferon and anti-inflammatory cytokine, such as interleukin-10 (IL-10), interleukin-4 (IL-4) levels can change after laryngeal transplantation. OBJECTIVE: To explore the expression of TNF-α and IL-10 in different expressive tissue layers and its relationship during the acute rejection episodes, and to evaluate the role of TNF-α and IL-10 levels in serum for prediction of early acute rejection after laryngeal transplantation. METHODS: Laryngeal heterotopic transplantations were performed in Wistar and Sprague-Dawley rats. According to different dosages of immunodepressant, all recipients were divided into three groups: Group 0 mg, Group 5 mg, and Group 10 mg. Untreated Sprague-Dawley rats served as normal control group. RESULTS AND CONCLUSION: Changes in serum TNF-α and IL-10 levels at postoperation days 3, 7 and 11 were positively correlated with these expressions in the epithelium mucosa and submucosa at various time points after transplantation. These indicate that the high-antigenicity of graft mainly concentrates on the layers of mucosa and submucosa. TNF-α and IL-10 concentrations can serve as indexes for predicting acute rejection after laryngeal transplantation.

Objective To investigate the effect of physical training on plasma N-terminal pro-brain natri- uretic peptide(NT-proBNP)levels in patients with chronic heart failure(CHF).Methods Eighty NYHAⅡ-ⅢCHF patients were randomly divided into a training group(n=42)and a control group(n=38).A 6-minute walk- ing test was performed within 24 hours after the patients were admitted.The 6-minute walking distance and plasma NT-proBNP levels were determined before and after 8 weeks of programmed physical training.The patients of both groups were treated with routine drugs for heart failure.6-minute walk training was only performed in the training group twice a day for 8 weeks.Results Physical training could significantly reduce plasma NT-proBNP levels and improve performance on the 6-minute walking test.Conclusions Physical training could significantly reduce plas- ma NT-proBNP levels and improve the motor function of patients with CHF,and could be helpful in delaying the de- velopment of CHF.
