[Objective] To evaluate the clinical efficacy of treatment of humeral shaft fracture with revolving intramedullary nails.[Method]Sixty-two cases with fracture of hume ral shaft were treated by revolving intramedullary nails between January 2000 and February 2006.Their were 38 male cases and 24 female cases.Their average age was 36.9(ranged 20～58).Fifty-fous cases were closed fractures,and eight cases were opened.Sixty-two cases with fracture of humeral shaft according to AO classification,41 cases were type A,15 cases were type B,6 cases were type C.Sixty-two patients with the humeral shaft fracture were treated with limited open reduction and minimally invasive internal fixation with revolving intramedullary nails.Scientific and rational rehabilitative treatment was carried out in each case after the operation.All patients were follow-up between 14 months and 30 months.The average follow-up period was 24 months.[Result]The fracture union occurred in sixty-two patients.The average healing time was 15 weeks.According to Rodriquez-Merchang shoulder functional score system,the excellent result was achieved in 36 patients,good in 20 and fair in 6.The excellent and good rate was 90.3%.All cases got good function recovery.The effects were satisfactory.There were no complications in all cases,such as infection,iatrogenic fracture,shortening,break of nail,fat embolism syndrome and peripheral nerve injury.[Conclusion]Revolving intramedullary nails for treatment of humeral shaft fracture is effective with litter interference with the blood supply of the bone fracture and with stable immobilization.Due to the abutment of the longitudinal bars along the entire length of the medullary canal wall,highly resistant to the rotational strength was achieved.The advances of revolving intramedullary nails are convenient in operative procedure with little invasive of operation,early function exercise,high raito of fracture healing and safety compared with the normal operative therapy.The operation indication and timing should be controlled strictly.The manipulation should be familiar.This kind of treatment is worth to be recommended.

Object To study the causes for the occurrence of red skin and dark green skin of Panax quinquefolius L. during processing and its mechanism. Methods To observe the phenomena and analyze the result which simulated the processing condition of P. quinquefolius based on its components. Results The cross section of P. quinquefolius began to appear light red at 40 ℃, lasting 72 h. Whereas the time of browning was shortened with the temperature rising. The cross section of P. quinquefolius turned green while dipping in solution of Fe 3+ ion of 0 01 mol/L for 25 min. The time of turning green was shortened with the increasing concentration of Fe 2+ , Fe 3+ solution. Conclusion The results show that red skin of P. quinquefolius was caused by the Maillard reaction while drying at the excessive higher temperature. Whereas the complex reaction between phenolic substances in P. quinquefolius and metal ions during processing might result in dark green skin of P. quinquefolius. This expounds the mechanism of red skin and dark green skin turning during the P. quinquefolius processing in the theory.

Objective To explore the damage effect of sonoporation on the prostate of rabbit,while opening up the blood-prostate barrier by microbubble mediated sonoporation.Methods Fifteen male New Zealand white rabbits were randomly divided into 3 groups:ultrasound (US) group,microbubble (MB) group,ultrasound and microbubble (US+MB) group.Ultrasound was insonated directly on the prostate.Optical microscope,electron microscope and apoptosis index (AI) with TUNEL method were applied to trace the changes of the prostate of rabbit under different conditions.Results There was no significant change in prostatic tissues of group US and MB under the optical microscope.Cytoplasm and nucleoli were stained equally,cells of glandular epithelium were intact and formed orderly.Glandular cavities in these two groups were change very slightly.Glandular epithelium cells of Group US+MB were organized optical under the optical microscope,and there was a mass of eosinophilic liquid in the glandular cavities.Vascular endothelial cell were intact and formed orderly and swollen mitochondria were observed under the electron microscope in MB group and US group.Swollen mitochondria,tight junctions among gland cells were opened,and infiltrated erythrocyte could be found under the eletron microscope in US+MB.AI of group US+MB was markedly higher than that of group US and group MB (P<0.01),and AI of group US was higher than that of group MB (P<0.01).Conclusions Microbubble mediated sonoporation causes damage in the prostate tissue of rabbit,while opening up the blood-prostate barrier with an increased permeability of the prostate.

AIM: To evaluate the efficacy of vitrectomy and pan-retinal photocoagulation followed with Ahmed implantation in management of neovascular glaucoma ( NVG) retrospectively.
METHODS: Vitrectomy combined with pan retinal photocoagulation and Ahmed implantation was performed on 15 cases ( 15 eyes ) with NVG. All patients were followed up for 12 ~ 36mo. The change of intraocular pressure (IOP), visual acuity, neovascularization of iris, complications were observed.
RESULTS: The visual acuity of 10 eyes was improved postoperative. IOP of postoperative 1, 6 and 12mo were decreased significantly compared with preoperative ( P<0.01 ) . Neovascularization of iris was reduced dramatically. No serious complications occurred.
CONCLUSION: Vitrectomy combined with pan retinal photocoagulation followed Ahmed implantation can manage NVG effectively.

ObjectiveTo investigate the effect of intrathecal injection of TRPV3-siRNA lentivirus on bone cancer pain(BCP) behaviors in rats.Methods40 female SD rats successfully received intrathecal catheter implantation and without motor dysfunction were randomly divided into 4 groups (n=10 in each group):Sham group (S),BCP group (B),negative control lentivirus group (C) and TRPV3-siRNA lentivirus group (T).Group B,C and T were induced bone cancer pain by intra-right-femur inoculation of Wallker 256 cells,while rats in group S were injected of inactivated cell.Rats in group T were intrathecally treated with 5 μl TRPV3-siRNA lentivirus while rats in group C received 5 μl negative lentivirus on 1~6 d after surgery.All the rats received pain behaviors including paw withdrawal thermal latency(PWTL) and paw withdrawal mechanical threshold (PWMT) at 1 d before BCP and 1,3,6,9,12,15,18 and 21 d after BCP.L4~L6 spinal cords were reserved for RT-PCR and Western Blot.ResultsCompared with group S,PWTL and PWMT of group B were decreased (P<0.05).On the 9th day,PWTL of group T was higher than that of group C((17.52±2.15)s vs (14.36±1.67)s,P<0.05).However,there was no significant difference in PWMT between group T and group C((16.89±1.54)g vs (15.53±1.36)g,P>0.05).The results of RT-PCR and Western blot demonstrated that the expression of TPPV3 in group T was decreased compared with that in group C(P<0.05).ConclusionIntrathecal injection of TRPV3-siRNA lentivirus can inhibit the expression of TRPV3 and thus alleviate symptom of PWTL,but not PWMT.

The course of fundamental operations in surgery is an important part of surgical teaching.It helps students to adapt to surgical practice quickly.During the teaching,there are some ways to improve teaching efficiency and quality,such as to know the new Chinese-English teaching material,the teaching purpose,the training of basic skills and aseptic principles of operation,the examination reform and regular teaching summery.
