Objective To investigate the reverse effect and mechanism of the extracted solution of chinese medicine MBC on the drug-resistance of K562/ADM in vitro. Methods MTT assay was used to determine the IC50 of ADM on K562/ADM cell line and the reverse multiples of the drug-resistance before and after MBC treatment. Flow cytometry(FCM) was applied to assess the intracellular concentration of Rh123. Results 8?10 -1 ?g/ml MBC increased cytotoxic effect of ADM on 562/ADM cells, the reverse multiple was 6 28, and MBC could increase the intracellular concentration of Rh123. Conclusion MBC could increase killing effect of ADM on the drug-resistant K562/ADM cell and partly reverse the drug-resistance of K562/ADM cell.

Objective To assess if there are differences in clinical features and prognosis of intersti-tial lung disease(ILD) between polymyositis(PM) and dermatomyositis(DM). Methods Medical records of 114 patients with PM/DM(31 PM-ILD, 83 DM-ILD) were reviewed retrospectively to analyze the demograph-ics , clinical manifestations, laboratory findings, high-resolution computed tomography (HRCT), pulmonary function tests (PFTs), blood gas analysis, treatments and prognosis. The differences of measured data were detected by descriptive statisitical analysis, and rates were detected by four-fold table Chi-Square test and Fisher′s exact test. Results The incidence of PM/DM-ILD was 35.8%(114/318) in this study, and DM was more prone to have ILD (χ2=5.019, P=0.025). There were significant difference in sex ratio between PM-ILD and DM-ILD(χ2=4.929, P=0.026). Arthralgia/arthritis was more common in DM-ILD than PM-ILD(χ2=7.756, P=0.005). In PM-ILD, ILD was often present before the diagnosis of PM (χ2=15.555, P<0.01),while it was opposite in DM-ILD(χ2=7.002, P=0.008). The frequency of anti-Jo-1 antibody was higher in PM-ILD than in DM-ILD(χ2=11.395, P=0.001). On HRCT, ground-glass opacity(χ2=7.940, P=0.005) and pericardial effu-
sion (χ2=6.322, P=0.012) were more frequently observed in PM-ILD, while patchy shadows were more frequent in DM-ILD (χ2=5.105, P=0.024). There was no difference in PFTs and blood gas analysis between the two groups. With the similar therapeutic regimen, the prognosis of DM-ILD was significantly worse than in PM-ILD (χ2=7.595, P =0.006). Conclusion There are significant differences in sex ratio, clinical manifestations, HRCT imaging findings, and prognosis between PM-ILD and DM-ILD. We propose that the difference in the immunopathological processes of PM and DM leads to different clinical features of ILD between PM and DM.

Objective To improve the management of blunt pancreatic trauma, and to explore the strategy of preserving the pancreatic endocrine and exocrine function to the full extent. Methods 20 cases of blunt pancreatic trauma were reviewed and analyzed retrospectively. The methods of operative treatment were analysed. Results All patients were cured. Depending on the general condition, abnomial signs and main pancreatic duct(MPD) injuries at the time of admission, patients received immediate operation or nonoperative treatment. Because of severe peritonitis and demonstrated MPD injury, 10 patients underwent immediate operations, including simple drainage in 6 cases, distal pancreatectomy in 1 patient, external drainage of the injured pancreatic duct for the second operation in 3 cases. Without the demonstrated MPD injury or clinical deterioration, 10 patients received nonoperative treatment under strict observation initially. 3 patients completed the nonoperative course and 7 patients underwent delayed operations, including Roux-en-Y pancreatic cyst-jejunostomy in 3 cases, external drainage of pseudocyst in e cases, pancreaticoduodenectomy in 1 patient because of the expanded hematoma in pancreatic head. Conclusions Blunt pancreatic trauma could receive individual pancreas-preserving treatment, which could improve the operational safety, avoid the resection of pancreas and preserve the pancreatic endocrine and exocrine function to the full extent.
