BACKGROUND:Chitosan is wel known as good biocompatibility and biodegradability;however, its extensive use in biomedical applications is restricted due to its poor transfection efficiency. OBJECTIVE:To prepare the polyethyleneimine-chitosan/DNA nanoparticles loading enhanced green fluorescent protein gene, and to detect their physicochemical properties and gene transfection efficiency towards chondrocytes in vitro.
METHODS:Low molecular weight polyethyleneimine was covalently linked to chitosan backbone to construct chitosan-graft-polyethyleneimine;then the chitosan-graft-polyethyleneimine was mixed with DNA nanoparticles, which loaded enhanced green fluorescent protein gene, by a complex coacervation method. The nanoparticle morphology was observed under a scanning electron microscopy. The sizes and zeta-potentials of the
nanoparticles were measured by a Marven-nano laser diffractometer. The binding capacity of plasmid DNA was evaluated by agarose gel electrophoresis analysis. The gene transfection experiments in vitro were performed towards rabbit’s chondrocytes. The gene transfection efficiency was measured with flow cytometry and under fluorescence microscope. How marked DNA entered into the nucleus of chondrocytes mediated by the nanoparticles was detected by laser scanning confocal microscopy.
RESULTS AND CONCLUSION:The prepared nanoparticles were mainly spherical, with an average size of (154.6±18.6) nm, and zeta-potential of (24.68±6.82) mV. The agarose gel electrophoresis analysis confirmed that the nanoparticles could effectively protect plasmid DNA from DNase Ⅰ-induced degradation. Gene transfection in vitro proved that the nanoparticles were efficient in transfecting rabbit’s chondrocytes and the expression of green fluorescent proteins was observed under fluorescent microscope, with a transfection efficiency of (23.80±1.74)%that was significantly higher than that of the naked plasmid DNA and chitosan/DNA nanoparticles (P<0.05). But no significant differences were observed between polyethyleneimine-chitosan/DNA nanoparticles and LipofectamineTM 2000. These findings indicate that the polyethyleneimine-chitosan/DNA nanoparticles can effectively protect plasmid DNA from nuclease degradation, and exhibit the favorable transfection ability towards articular chondrocytes.

Objective To compare the efficacy of suprainguinal approach and pubic tubercle approach to obturator nerve block (ONB) in patients undergoing transurethral resection of bladder tumor.Methods Sixty ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 41-80 yr,with body mass index of 17.5-31.0 kg/m2,scheduled for elective transurethral resection of bladder tumor,were randomly divided into 2 groups (n =30 each) using a random number table:pubic tubercle approach group (group P) and suprainguinal approach group (group S).Nerve blocks were performed using a 100-mm insulated needle for ONB (21-gauge) under the guidance of a nerve stimulator.In group P,the insertion point of the needle was 1.5 cm lateral and 1.5 cm inferior to the pubic tubercle.In S group,the insertion point of the needle was at the midpoint of the line drawn in the inguinal crease between the femoral artery and the inner border of the adductor longus tendon and the needle was advanced 3 cm cephalad in the major axis of thigh.The number of puncture eliciting contraction of adductor muscle,time taken to elicit contraction of adductor muscle starting from onset of puncture,depth of puncture,and highest visual analog scale (VAS) pain scores during application of the block were recorded.The myodynamia of adductor muscle was evaluated.The development of complications was also recorded.Results Compared with group P,the number of puncture,highest VAS scores,and myodynamia of adductor muscle at 4 and 6 min of blockade were significantly decreased,the time taken to elicit contraction of adductor muscle was shortened,and the success rate of puncture at first attempt was increased in group S (P ＜ 0.05 or 0.01).There was no significant difference in the incidence of puncture point bleedings between the two groups (P ＞ 0.05).Conclusion The suprainguinal approach for ONB offers more accurate location,faster onset,lighter degree of noxious stimulation and better safety than the pubic tubercle approach in patients undergoing transurethral resection of bladder tumor.

Objective To evaluate the safety and efficacy of percutaneous endobiliary radiofrequency ablation combined with biliary stenting in treating malignant obstructive jaundice. Methods Percutaneous endobiliary radiofrequency ablation combined with biliary stenting was carried out in 2 patients with malignant obstructive jaundice after they received percutaneous transhepatic biliary drainage. The curative effect, complications and stent patency at 50 days after the treatment were recorded. The results were analyzed. Results Successful endobiliary radiofrequency ablation and intraluminal stent implantation was accomplished in both patients, with a technical success rate of 100%. Segmental radiofrequency ablation procedure was employed. After the treatment the serum total bilirubin level was significantly decreased. No bile duct bleeding, perforation of bile duct, bile leakage or other serious complications occurred. The stent remained unobstructed during the follow - up period of 50 days. Conclusion As a new treatment for malignant obstructive jaundice, percutaneous endobiliary radiofrequency ablation combined with biliary stenting is clinically safe and effective, although its long - term efficacy needs to be further proved with randomized controlled trials.
