Aim To establish a resistant human osteosarcoma cell line(Saos-2/ADM1and Saos-2/ADM4)from the Saos-2 cell line and study its resistant mechanisms.Methods Saos-2 cells were pulse exposed in gradually increased dose of ADM culturemedium.The sensitivity of the resistance drug from the Saos-2、Saos-2/ADM1 and Saos-2/ADM4 cell lines to ADM、DDP、EPI、MTX、THP and PTX was measured by MTT assay.The morphology and ultramicro structure of the cell lines were observed by optical microscopy and transmission electronic microscopy.The expression level of MDR1 mRNA、MRP mRNA and their proteins P-gp、MRP was examined by reverse transcription polymerase chain reaction and immunohistochemistry.Results Resistance cell lines were established after 167 days.The resistance index to methotrexate of the Saos-2/ADM1and Saos-2/ADM4 cell lines to ADM was 49.8 and 74.6 times than that of Saos-2 respectively.The two cell lines had resistance to MTX、IFO、EPI、THP and PTX(P0.05).Disordered structure of the Saos-2/ADM1and Saos-2/ADM4 cells was observed through microscopy.The cells appeared in coenocytic.The decrease of cell villus and the increase of nucleoli were observed through transmission electronic microscopy.The proliferation ability of Saos-2/ADM1and Saos-2/ADM4 cells decreased significantly.MDR1 mRNA、MRP mRNA、P-gp and MRP showed positive staining in resistance cell lines.Conclusion The genes of MDR1 mRNA、MRP mRNA and their corresponding proteins participated in the formation of multidrug resistance in resistant adriamycin cell line.These newly-described resistant osteosarcoma cell lines were useful models for further characterization of drug resistance in osteosarcoma and for the development of treatment protocol.
4.Changes of S-100B Protein in Umbilical Cord Blood of Asphyxial Neonates with Hypoxic-Ischemic Encephalopathy and Its Clinical Significance
Journal of Applied Clinical Pediatrics 2006;0(14):-
Objective To study clinical significance of S-100B protein in umbilical cord blood of asphyxial neonates with hypoxic-ischemic encephalopathy(HIE).Methods Forty-three cases of healthy infants were regarded as control group(group 1).Sixty cases of asphyxial neonates were divided into two groups(44 cases without HIE as group 2;another 16 cases with HIE as group 3).S-100B protein levels in umbilical cord blood of three groups were measured with enzyme-linked immunosorbent assay retrospectively. Results Levels of S-100B protein in group 1,group 2 and group 3 were(1.055?0.356) ?g/L,(1.572?0.533) ?g/L and(2.394?(0.943) ?g/L,) respectively.S-100B protein levels in umbilical cord blood of group 2 and group 3 were significantly higher than that of group 1(t=2.306,7.991 P

Through study on Bianque Shenying Zhenjiu Yulong Jing (Bianque's Classic of Effective Acupuncture Prescriptions), acupuncture experiences and ideology of WANG Guo-rui, an acupuncture physician of the Yuan Dynasty (1271-1368), is discussed in this article. Inherited and carried forward DOU's acupuncture theory, WANG Guo-rui encouraged to use experiential points and to expand extra points. Penetrating needling method was created, and the application of acupoints according to needling opportunities and seasonal factors were enriched by him. Great importance was also attached on treatment according to differentiation of syndromes, which including the simultaneous acupuncture and moxibustion, simultaneous reinforcing and reducing, reducing after reinforcing, reinforcing after reducing, predomination of reducing and predomination of reinforcing. The flexible treating methods are still extensively adopted in clinic nowadays. WANG Guo-rui is a master of clinical acupuncture who made great contribution to the development of acupuncture and moxibustion.

Aim To investigate the alteration of Wnt/β-catenin signaling pathway in early diabetic rat myo-cardium and clarify its role in development of diabetic cardiomyopathy. Methods The diabetes mellitus ( DM) model was prepared by intraperitoneal injection of streptozotocin ( STZ, 60 μg · g-1 ) . The alteration of Wnt/β-catenin signaling pathway was determined by Western blot and immunohistochemistry. HE staining was used to analyze the change of myocardial pathologi-cal structure. Results Cardiac histological analyses revealed that DM induced cardiomyocyte degeneration and necrosis. Myocardial Wnt2, β-catenin and c-Myc were enhanced in 2 wk DM compared with control group while DKK1 showed no significant alteration. Conclusion Wnt/β-catenin signaling pathway is acti-vated in early diabetic myocardial injury. Further re-searches on its role in DM myocardium may find a new therapeutic target for diabetic cardiomyopathy.

Objective To develop an electronic infusion alarm system with low cost and high safety and reliability.Methods The system was composed of modules of sensor, control, alarm and DC power supply. The integrated operational amplifier was used to amplify the voltage signals from the cantilever sensor, and NE555 timer controlled the system give out alarm when 10% liquid remained in the bottle.Results The system could alarm when 10% liquid remained in the bottle, and three gears were designed for the common infusion bottles in the market.Conclusion The system is easy to operate and maintain, and thus can be popularized in all hospitals and clinics.

Objective To evaluate the efficacy and safety of conventional 2940 nm Er∶YAG laser and pixel laser combination therapy.Methods From Jan.2010 to Jun.2013,32 cases of different types of superficial scars had been treated with this combination therapy.All patients were treated with the low-power 2940 nm Er∶YAG laser,and then immediately with pixel laser at higher power.The morphological changes of the scar before and after treatment,and adverse reaction were recorded.The satisfaction of patients was collected.Results Based on imaging data,significant efficacy was achieved in 14 cases (43.8%),effective in 12 cases (37.5%),relatively effective in 5 cases (15.6%) and ineffective in 1 case (3.1 %).The total efficacy rate of combined therapy reached 95.3 %.Very satisfaction to the treatment was 13 cases (40.6%),satisfaction in 10 cases (31.2%),relative satisfaction in 7 cases (21.9%) and no satisfaction in 2 cases (6.3%).The total satisfactory rate reached 93.8%.The only observed side effect was the erythema reaction at irradiated area.Conclusions The combined therapy of conventional 2940 nm Er∶YAG laser and pixel laser is an uncomplicated and safe way to treat superficial scars with little reverse reaction.
