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.

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.

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 investigate the relationship between interleukin 1β( IL?1β) , interleukin?33 ( IL?33) , neutrophil?to?lymphocyte ratio ( NLR ) and atrial fibrillation. Methods Eighty?two patients with nonvalvular atrial fibrillation treated in the department of cardiology in the Fourth People′s Hospital of Jinan from October 2015 to October 2016 were enrolled in the study,including 43 patients with persistent atrial fibrillation and 39 patients with paroxysmal atrial fibrillation. 50 healthy subjects were selected as the control group. Enzyme linked immunosorbent assay (ELISA) was used to determine the concentration of IL?1βand IL?33,and the left atrial diameter ( LAD) was measured by echocardiography. Results ( 1) The concentrations of IL?1β,NLR and LAD in the paroxysmal atrial fibrillation group were (24. 44±4. 89) ng/L,(2. 51±1. 22) %,(36. 16± 6. 12) mm,the concentrations of IL?1β,NLR and LAD in the persistent atrial fibrillation group were (26. 95±5. 86) ng/L,(5. 7±1. 8) %,(39. 36±4. 78) mm and the values in the control group were (19. 53±4. 51) ng/L,(1. 82 ± 0. 41 ) %, ( 33. 31 ± 2. 89 ) mm, respectively. The differences among the three groups were statistically significant ( F=16. 74,11. 82,14. 85,P<0. 01) . The indexes of paroxysmal atrial fibrillation group and persistent atrial fibrillation group were higher than those of the control group ( P<0. 01 ) . ( 2 ) In the persistent atrial fibrillation group, NLR and LAD were ( 5. 7 ± 1. 8 )% , and ( 39. 36 ± 4. 78 ) mm, higher than those of the paroxysmal atrial fibrillation group ( (2. 51±1. 22)%,(36. 16±6. 12) mm),the differences were statistically significant ( P<0. 01) . However,the level of IL?1βin the persistent atrial fibrillation group was not significantly different from that in the paroxysmal atrial fibrillation group ( (26. 95±5. 86) ng/L vs. (24. 44±4. 89) ng/L,P>0. 05). (3) The concentrations of IL?33 in the paroxysmal atrial fibrillation group,atrial fibrillation group, control group were ( 48. 31 ± 4. 72 ) ng/L, ( 50. 03 ± 2. 18 ) ng/L, ( 56. 87 ± 5. 12 ) ng/L, respectively. The difference among the three groups has no statistical significance ( F=2. 52, P>0. 05 ) . ( 4 ) NLR level was positively correlated with LAD ( r=0. 32,P=0. 002) . There was no significant correlation among IL?1β,IL?33 and LAD ( r=0. 16, P=0. 11, r=0. 02, P=0. 37 ) . Conclusion The levels of IL?1β, NLR and LAD in peripheral blood of patients with atrial fibrillation were significantly higher than those in patients with sinus rhythm,and there was a positive correlation between NLR and LAD.

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.

Objective To explore the regulating mechanism of inducible nitric oxide synthase(iNOS) in hepatic injury of obstructive jaundice (OJ) in vivo and in vitro experiments. Methods (1) Rat hepatocytes were isolated by in situ collagenase perfusion and primary culture. Hepatocytes were pretreated with various concentrations of iNOS inhibitor SMT for 20 min. After pretreatment, 50?M GCDC was added for an additional 24hr. Cells were next detected by FCM and TUNEL.(2) Experimental obstructive jaundice (BDL) was induced by double ligation of the bile duct in rats. After BDL for 3d、7d、14d、and 21d, the apoptotic status in liver of all rats were determined with TUNEL, and iNOS protein in liver of OJ was ditermined with immunohistochemistry method. Results (1) SMT decreased GCDC-induced apoptosis in a concentration-dependent manner. (2) The apoptotic rate of liver was related to length of time of OJ. Apoptosis index (AI) was highest from rats with 14d bile duct ligation. The stronger the iNOS expression, the higher was the number of apoptotic cells that was found in OJ. Conclusions iNOS is involved in the regulation and the occurrence and progression of hepatic injury of obstructive jaundice.
