Objective To investigate the feasibility of aortic and mitral valves replacement under video-assisted thoracoscope.Methods The subjects included 16 dogs(Experimental Group) and a clinical volunteer(Clinical Group).The procedure was performed under extracorporeal circulation with femoral artery and vein intubation.An incision 4~5 cm in length and two 1.5 cm ports were made in the right chest wall.The superior and inferior vena cava were cross-clamped by a self-made clamp and the myocardium was protected by cold cardioplegic coronary perfusion.Artificial mechanical aortic and mitral valves were intermittently sutured.Results In the Experimental Group: the time of extracorporeal circulation was 104~196 min(143.2?46.5 min) and the ascending aorta cross-clamped time was 58~128 min(82.4?26.1 min).Autopsy findings showed satisfactory valve suture fixation,without thread loosing or paravalvular rupture.In the Clinical Group: the time of extracorporeal circulation was 157 min,the ascending aorta cross-clamped time was 112 min,the time of mechanical ventilation was 10 h,and the drainage volume,150 ml.The patient was discharged from hospital on the 10 postoperative day.Follow-up observations for 9 months found no paravalvular leakage or other complications.Echocardiography showed normal prosthetic valve movement.Conclusions Video-assisted thoracoscopic aortic and mitral valves replacement is technically feasible.

Background Spectral-domain optical coherence tomography (SD-OCT) can quantitatively analyze some ocular parameters in vivo.Although human ocular parameters have been obtained by SD-OCT,few studies were performed in animal experiment.Objective This study was to investigate the anterior and posterior segment parameters of C57BL/6 mice and pigmented rabbits using SD-OCT in vivo.Methods Some anterior and posterior segment ocular parameters,including the central corneal thickness (CCT),anterior chamber depth (ACD),white-to-white (WTW),optic nerve head (ONH) depth/width and retinal thickness,were measured in 8 eyes of 4 health SPF C57BL/6 mice and 12 eyes of 6 health SPF pigmented rabbits using SD-OCT.Results For C57BL/6 mice,Cornea,iris,lens in pupil area were clearly exhibited by SD-OCT.Mean CCT,ACD and WTW were (96±9)μm,(460±8) μm and (2.86 ± 0.41) mm pre-mydriasis,respectively,the corresponding values of post-mydriasis were (96±8) μm,(356±20)μm and (2.87±0.62)mm.There were no statistical differences of CCT and WTW between pre-and post-mydriasis (t =0.478,P =0.647 ; t =-0.737,P =0.485).ACD of post-mydriasis was significantly shallower than that of baseline (t =-13.022,P＜0.001).For the pigmented rabbits,the thickness of corneal thinnest point,retinal thickness,ONH depth and width were (370 ± 10) μm,(175 ± 4) μm,(1.35 ± 0.51) mm and (4.52±0.82) mm,respectively.Conclusions As a non-contact and non-invasive technology,SD-OCT can provide not only high resolution cross-sectional ocular images,but also high precise quantitative parameters for both C57BL/6 mouse and pigmented rabbit in vivo.

Objective To evaluate the effect of clinic-pathological variables on prognosis and recurrence of the aged women suffered from borderline epithelial ovarian tumors. Methods The clinical and follow-up data of 102 cases were analyzed retrospectively. Univariate and multivariate logistic regression analysis were used to assess independent prognosis and recurrence factors.Results The postoperative accessory treatment, peritoneal implantation and lymph nodes metastasis could influence the 5-year survival rate(χ2=19.311, 11.054, 18. 559, all P＜0.01). The surgery procedure, peritoneal implantation, lymph nodes metastasis and microinvasion could influence the recurrence rate(χ2=23.606, 23.583, 25.774, 23.583, all P＜0.01). The logistic regression model showed that the postoperative accessory treatment and peritoneal implantation were the two independent prognosis factors (OR=0.060, 35.319, all P＜0.01). The surgery procedure,peritoneal implantation and microinvasion were the three independent factors affecting recurrence(OR =0.001, P＜0.05;OR=60.952, P＜0.05;OR=88.874, P＜0.01). Conclusions The early standard treatment on borderline epithelial ovarian tumors of the aged women have an excellent prognosis, the risk of recurrence remains in some patients. We emphasize that these patients with highrisk factors should be main surveillance population.

Objective To investigate the expression of T cell immunoglobulin domain and mucin domain (TIM)-3 and its ligand Galectin-9 in the peripheral blood of initial systemic lupus erythematosus (SLE)patients,and explore their effects on SLE.Methods The percentages of CD4+TIM-3+,CD8+TIM-3+cells from 33 SLE patients and 26 normal controls were detected by flow cytometry,and the Galectin-9 gene expression of PBMCs was determined by real-time PCR The SLE Disease Activity Index(SLEDAI),C3 level and lymphocyte count were evaluated.Mann-Whitney U test was used for independent samples analysis and Spearmen's test was used for correlation analysis.Results The percentages of CD4+TIM-3+ and CD8+TIM-3+ cells were markedly increased in SLE group than those of the control group(P<0.01).In particular,the CD4+TIM-3+,CD8+TIM-3+ level Was positively correlated with SLEDAI (r=0.517,P＜0.01;r=0.400,P＜0.05);but negatively correlated with C3(r=0.487,P＜0.05;r=0.395,P＜0.05).The Galectin-9 mRNA in SLE PBMCs was higher than that of the controls(P<0.05).Conclusion TIM-3-Galectin-9 pathway may be involved in T cell immune regulation of SLE,and is related to disease activity.

There are many methods for internal and external fixation of limbs fractures,such as plaster,splint,and traction.But the disadvantages such as destroyed local blood supply,unreliable fixation,inappropriate dynamic and static combination,postoperative nursing,delayed functional recovery and complications limit their application.Multifunctional external fixation apparatus has been used to treat limbs fractures.It avoids to dissect surrounding tissues and does not damage blood supply out of medullary cavity,which benefits wound treatment,early functional exercise,prevents joint adherence,improves cure rate,reduces complications and avoids second surgery.Moreover,this method is an effective fixation,saves treatment time and prevents adverse results due to treatment for other wounds.In addition.it can also be used to treat bone nonunion,infective fracture,bone defect and other fracture complications.

0.05).Conclusion There may be no significant difference in sensory block,motor block and prevalence of adverse effects between injection rates of 0.27 mL/s and 0.04 mL/s in spinal anesthesia with 20 mg isobaric ropivacaine.

ObjectiveTo study the effect of head acupuncture combined with rehabilitation techniques on movement function of upper limbs after stroke.Methods80 patients with stroke were divided randomly into four groups, group 1 for head acupuncture and rehabilitation techniques, group 2 for rehabilitation techniques, group 3 for head acupuncture and group 4 for control. Fugl Meyer Assessment(FMA) and Facility Assessment For Function of Upper Limbs were applied to assess movement function before and after treatment.ResultsThe scores of FMA and Facility Assessment For Function of Upper Limbs rised more significantly in group 1,2, and 3 than group 4 (P<0.01) and group 1 outgo group 2,3 yet(P<0.05).Conclusions Head acupuncture combined with rehabilitation techniques can improve the movement function of upper limbs of the stroke patients.
