Objective The aim of this study is to summarize primarily the application range and the clinical effect of the minimally invasive direct cardiac surgery (MIDCS).Methods From April 2010 to August 2011,108 operations had been performed in our centre using MIDCS,among of which 44 males and 64 females,mean age (44.3 ± 16.4 ) years old,mean weight (60.0 ± 12.0 ) kg.These operations included 29 MVR operations (replacement with mechanical valve 19,with tissue valve 10),17 AVR operations( replacement with mechanical valve 11,with tissue valve 6 ),5 MVP operations,6 MVR + AVR operations (replacement with mechanical valve 5,with tissue valve 1 ),12 VSD repair operations and 23 ASD repair operations,9 MIDCAB operations,1 MVR + CABG oparation,2 PECD correction,1 repair of ruptruec chordae tendineae of tricuspid septum and 1 Ebstein deformity correction operation.Concomitant procedures included 19 TVP operations and 11 radiofrequency ablation operations.Except MIDCAB operations,other operations are performed with closed type extracorporeal circulation.Conversion to median sternotomy was necessary in only two patients ( 1.9％ ).Results Mean cardiopulnonary bypass time and aortic eross-clamp time were ( 104.4 ± 59.3 ) minutes and ( 66.7 ± 52.8 ) minutes respectively,74 patients ( 92.5 ％ ) recover to beat automatically after heart ceased operation.Median mechanical ventilation time was ( 14.5 ± 11.9 ) hours,Median intensive care unit stay was ( 18.8 ± 15.3 ) hours,median hospital stay post operative was (6.9 ± 2.9) days.Median incision length was (5.3 ± 1.2 )cm.Median draining volume was( 337.6 ± 240.9 )ml in the first day after operation,No transfusion occurred in 72 patients(66.7％ ).Hospital mortality was 0.No re-exploration for bleeding and sternal wound infection.When leaving hospital,94 being of heart functional class Ⅰ,8 of class Ⅱ,6 of class Ⅲ.Conclusion MIDCS was associated with good operative effect in the near future,superior safety and broad application range.Furthermore MIDCS has minimally invasive,less postoperative bleeding,fewer blood transfusions,good cosmesis,as well as the absence of sternal wound infection.It may be safely performed on selected patients with low postoperative mortality and morbidity.

Cyclin-dependent kinase 10 (CDK10) function as a tumor suppressor gene through regulating cell cycle interacting with transcription factor Ets2.Studies demonstrate that the downregulation of CDK10 expression occurs in multiple cancer types,indicating a potential application of CDK10 as a molecular diagnostic marker as well as therapeutic target.

Objective To discuss the clinical value of transesophageal echocardiography used in extracorporeal circulationcardiac valve replacement. Methods 89 patients received extracorporeal circulation cardiac valve replacement in our hospital from January 2012 to December 2014 were included in the study. Transesophageal echocardiography were performed preoperatively, intraoperation and postoperatively and the findings were compared to the result of preoperation transthoracic echocardiography exam. The measurement of aortic annulus diameter and detection rates of calcification obtained by transthoracic and transesophaged echocardiography were compared. Changes in heart function parameters before and after operation were compared. The alternations in surgery plan made after pre-operative transesophageal echocardiography exam and any relevant treatment or procedure performed according to intra-operation transesophageal echo findings were recorded. All the patients were followed up for 6 months - 40 months. Results Before extracorporeal circulation cardiac valve replacement, the aortic annulus diameter measured and detection rates of calcification by transthoracic echocardiography were smaller and lower than actual surgical pathology results ( P < 0. 05 ) . No differences in the results from transesophageal echocardiography of two-dimensional and three-dimensional examination when compared to pathological findings ( P > 0. 05 ) . Conclusions For patients receiving extracorporeal circulation cardiac valve replacement, transesophagus echocardiography examination is helpful to guide the selection of valve stent and operation methods.

0.999 3), the recovery rate was 96.9%-104.0%,RSD was 1.54%-2.03%. Conclusion The method is simple and rapid, with good sensitivity and selectivity, and it is applicable to the determination of trace cadmium in drinking water or food.

In an attempt to overcome the limitations of titanium in dental and orthopaedic clinical applications, a new method has been developed to prepare calcium carbonate coatings on sandblasted and acid-etched (SA) titanium implants. The purpose of this study was to investigate the effect of calcium carbonate-SA (CC-SA) implants on osseointegration in vivo. The surfaces of SA and CC-SA implants were characterised for surface morphology and surface chemistry. Subsequently, these two kinds of implants were implanted in the femoral condyles of rabbits. The implants were retrieved and prepared for histological and histomorphometric evaluation 1, 2, 4, 8 and 12 weeks after implantation. Significantly higher values of bone-to-implant contact of the entire implant except the gap area (BIC_ALL) and the bone-to-implant contact of the gap area (BIC_GAP) were found in animals with the CC-SA implants than in those with the SA implants at 4 weeks. Higher values of total gap bone were found in those with the CC-SA implants than in those with the SA implants at 1, 2 and 4 weeks. In conclusion, the current findings demonstrate that the calcium carbonate coating can improve and accelerate the early ingrowth of bone and osseointegration at the early healing phase. This may reduce clinical healing times and thus improve implant success rates.

The fermentation conditions of high 1.3 -propanediol-producing strain E. aero-N-56 were determined in this Paper. The optimum conditions of producing 1.3-PD were: initial pH 7.0, temperature 30℃, culture time 48 h, inoculum size 9% . Under the optimum conditions: the 1.3-PD productivity reached up to 23.68 g/L?d; the 1,3-PD yield of E. aero-N-56 up to 47.36 g/L in 30 L fermentor.
