Purpose: To evaluate the efficacy, safety and survival of low molecular weight heparin ( LMWH) plus chemotherapy in patients with advanced non-small cell lung cancer. Methods: 46 patients with NSCLC were randomized into chemotherapy plus LMWH. (study group) and chemotherapy only( control group). Both groups received two cycles of MVP regimen (MMC 6 mg/m2, YDS 3 mg/m2 x 2, DDP 90 mg/m2). Patients in the study group were treated with LMWH 5000u twice daily from the third day before chemtherapy up to 7 days. Results: The response rate was 56. 5% (13/23) for the study group and 39. l%(9/23) for the control group. Median survival time( MST) and 1-year survival rate were 12, 1 months(95%CI:8.52~14.64) and 52.2% for the study group compare 8.4 months(95%CI:6.15 ~ 10. 85) and 34. 8% for the control group. There were significant differences for MST( 12. 1 vs 8. 4) and 1 year survival rate(52. 2% vs 34. 8%) in the study group as compared to the control group. No difference in response rate and toxicities were found between the two groups. Conclusions: Chemotherapy( MVP regimen) plus LMWH is effective and safe. Prolonged survival was observed in patients who received MVP regimen plus LMWH.

Objective: To optimize the formulation parameters of solid lipid nanoparticles (SLN) of Silymarin by Box-Behnken experimental design. Methods: A three-factor and three-level Box-Behnken experimental design was employed using emulsion evaporation-low temperature solidification technique to prepare SLN with Silymarin as model drug. Response surface methodology was used to investigate the factors affecting entrapment efficiency (EE), drug loading (DL), and particle size. Binomial mathematical model-optimized formulation was established with EE, DL, and particle size as response values. Results: The optimal formulation was as follows: the amount of glycerol monostearate was 5.05%, the concentration of Poloxamer 188 was 7.25%, and the amount of drug was 15%. Conclusion: The Box-Behnken experimental design could be used to optimize the SLN of silymarin.

Objective To study the clinicopathological features,diagnosis and treatment of carcinoid tumors of the urinary bladder. Methods The clinical,histopathologic data of 4 carcinoid tumors of the urinary bladder were retrospectively analysed.The bladder carcinoid was diagnosed in 3 male patients and 1 female patient with age from 54 to 79 years.All patients were presented with gross hematuria,but with no clinical manifestations of the carcinoid syndrome such as flush,tachycardia,diarrhea.Cystoscopies showed 5 mm?5 mm to 25 mm?30 mm sessile polypoid masses. Results One patient received radical cystectomy followed by radiotherapy,3 patients received partial cystectomy.Two patients died of the tumor metastasis at survival interval 5 years and 3 months,respectively;other 2 patients were still alive 19 years and 8 months following the surgical treatment.Two cases were stage Ⅱ,and other 2 cases were stage Ⅲ.Histologically,tumor cells exhibited strong argyrophilia and electron microscopy revealed characteristic dense-core granules. Immunohistochemical testing showed the cancer cell was positive for chromogranin A and keratin. Conclusions Carcinoid of the urinary bladder is uncommon,the diagnosis depends on histopathological and immunohistochemical tests.Based on the degree of infiltration,size,location,lymph node metastasis,different surgical intervention can be choosed.

Purpose:To identify clinical predictors of stage ⅢA-N2 in patients with non-small cell lung cancer. Methods:From March 1995 to February 1998, 118 patients with pathological stage ⅢA-N2 non-small cell lung cancer who underwent a resection by Shanghai Chest Hospital were analysed. Prognostic factors were estimated from the date of operation using the Kaplan-Meier and log-rank analysis. The Cox regression model evaluated the influence of factors on the survival. Results:The overall of 3-year and 5-year survivals of the 118 patients were 40.5% and 18.4%. Margin, the number of N2 lymph nodes and stations, the cycles of adjuvant chemotherapy were associated with survival. In a multivariate analysis, the number of N2 lymph nodes and the cycles of adjuvant chemotherapy significantly influenced survival. Conclusions:The number of N2 lymph nodes and the cycles of adjuvant chemotherapy were important prognostic factors of stage ⅢA-N2 non-small cell lung cancer.

Objective To observe the influence of technetium [99Tc] methylenedipho-honate (99Tc-MDP) on osteoclastogenesis induced by receptor activator of NF-κB ligand (RANKL) and macrophage-colony stimulating factor (M-CSF)in peripheral blood mononuclear cells in patients with rheumatoid arthritis, and to study the mechanism of 99Tc-MDP in osteoclast differentiation. Methods The monocytes/macrophages were isolated from peripheral blood in patients with rheumatoid arthri-tis, incubated in RPMI-1640 with receptor activator of NF-κB ligand (RANKL, 25 μg/L), macro-phage-colony stimulating factor (M-CSF, 25μg/L ) and different concentrations of 99Tc-MDP (5, 10, 20,and 50 mg/L) for 4,12, and 20 days. Tartrate resistant acid phosphatase staining was used to observe the formation of osteoclasts. Results After 12 or 16 days culture of peripheral blood mononuclear cells, plenty of large nultinuclear cells could be found on the coverslips. 99Tc-MDP markedly inhibited those changes and the inhibitory effects were increased as the concentration of 99Tc-MDP increased (P<0.05). Conclusion 99Tc-MDP probably has some protective effect on rheumatoid arthritis by inhibiting osteoclast formation.
