Circulating tumor cells(CTCs)are essential for establishing metastasis and recurrence in non-small cell lung cancer(NSCLC). With the development of detection technique,results from recent studies suggest that CTC level could be a supplement for TNM staging system and a prediction marker of prognosis and therapeutic efficacy,and even could be applied for risk assessment of early NSCLC. Furthermore,as a non-invasiveliquid biopsy,detection of CTC can reflect the molecular biology and genetics characteristics of the primary tumor,and subsequently assist in selecting an optimal individualized treatment.

OBJECTIVETo investigate the role of autophagy in acute lung injury (ALI) caused by multiple trauma in rats via pretreat with 3-methyladenine (3-MA).

METHODSForty-five Sprague-Dawley male rats, with age of 4 months and body weight of 250-300 g,were randomly divided into three groups. In the sham group, the rats received sphenotresia only;in the control group, the rats were made model of femur shaft fracture combined with brain injury, and treated with physiological saline by abdominal cavity at 1 hour before making model; in the 3-MA group, the rats were made model of femur shaft fracture combined with brain injury,and treated with 3-MA of 10 mg/kg by abdominal cavity at 1 hour before making model. Histologic changes and the concentration of related inflammatory factors in the damaged lung tissue were examined at 48 h after opteration, at the same time, the effect of 3-MA on the expression of LC-3 II and Beclin-1 was examined through reverse transcriptase polymerase chain reaction technique (RT-PCR).

RESULTSCompared with sham group, LC-3 II and Beclin-1 level in control group at 48 h after operation were obviously increased (P < 0.01). Compared with control group, LC-3 II and Beclin-1 level in 3-MA group at 48 h after operation were obviously decreased (P < 0.01). Compared with sham group, the level of proinflammatory cytokines (TNF-α and IL-6) in control group obviously enhanced (P < 0.01). Compared with control group, above items in 3-MA group was obviously lower (P < 0.01). Compared with control group,the histopathological damage of lung in 3-MA group obviously reduced (P < 0.01).

CONCLUSIONAutophagy can aggravate the acute lung injury caused by fracture of shaft of femur combined with brain injuries,but 3-MA can reduce tissue damage by inhibiting the autophagy and inflammatory response.

Objective To evaluate the function and synchronization of left atrial in patients with chronic heart failure(CHF) by real-time three dimensional echocardiography (RT-3DE).MethodsThirty healthy controls and thirty-two patients with CHF were studied.The CHF were divided into group CHF1 with the normal of left ventricular filling pressure and group CHF2 with the elevated of that.From the volume-time curve of RT-3DE workstation,the maximum volume (LAVmax),the minimum volume (LAVmin),the volume before contraction (LAVp) of left atrial were acquired.Accordingly,the total,passive and active ejection fraction could be calculated.The synchronization parameters derived from RT3DE were the dispersion and maximum difference of time to minimum volume for left atrial segments (Tmsv- 16-SD,Tmsv 12-SD,Tmsv-6-SD,Tmsv- 16-Dif,Tmsv 12-Dif,Tmsv-6 Dif).The index of volume and time were corrected by the body surface area and interval of R-R,respectively.The correlation were analysed in them.Results ① All the index of volume before and after correction were gradually increasing from control to CHF2 group,but the LATEF,LAPEF and LAAEF were just the reverse,with all parameters had significant difference among total groups( P ＜0.01 ).②The synchronization parameters were significantly higher from control to CHF2 group( P ＜0.01 ).Comparing between two groups,no significant difference of the synchronization parameters were found between CHF1 group and CHF2 group ( P ＞ 0.05),except Tmsv-16-SD％ and Tmsv-16-Dif％ ( P ＜0.01 ).③The Tmsv-16-SD％ and Tmsv-16-Dif％ had a positive correlation with the index of volume and a negative correlation with the ejection fraction.The most significantly correlation parameters was LAVmaxI,with r =0.75 and P ＜0.01.ConclusionsThe function of left atrium are reduced in patients of CHF,there are dyssynchronization.The higher of the filling pressure of left ventricle,the lager of the dyssynchronization of left atrium.RT-3DE may paly important roles in the evaluation of function and synchronization of left atrium.

ObjectiveUsing large sample clinical study to reevaluate the safety and efficacy of recombinant human growth hormone(ANSOMONE) in treating pediatric growth hormone deficiency(GHD).Methods1012 cases were administered with ANSOMONE at a dose of 0.1 IU · kg-1 · d -1 in bedtime for 6 months.The alteration of mean height,growth rate,height standard deviation scores,bone age,and anti-GH antibody and occurrence of adverse effects were observed.ResultsThe growth rate was promoted from ( 2.50 ± 0.85 ) cm/year to ( 13.44 ± 4.27 ) cm/year,the net growth rate was( 10.94 ±3.69)cm/year.There was significant difference between the pre-treatment and post-treatment patients ( P ＜ 0.01 ).The post-treatment anti-GH antibody positive rate was 13.34％,which had no obvious effect on the efficacy.Few patients exert transient inflammation reactions,which disappeared with any treatment.ConclusionANSOMONE had significant efficacy,and could promote the height increase obviously.It had good safety without any obvious side effect and early-maturing effect.

Objective To observe the clinical efficacy of percutaneous vertebroplasty (PVP) with percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture(OVCF) by systematic review. Methods From September 2005 to March 2009,46 cases of fresh OVCF were treated. Patients were divided into 2 groups (A, B), according to Jikei grade, Genant semiquantitative method, injury vertebra number. Twenty-five cases(group A)were treated by PVP,8 males and 17 females with the age of 52 - 78 years (average 69). Vertebra segment of fracture was within T6 - L5 (14 in case thoracical vertebrae and 11 lumbar vertebrae). Twenty-one cases(group B)were treated by PKP,There were 6 males and 15 females with the age of 54 - 82 years (average 71). Vertebra segment of fracture was within T6 - L4 (12 in case thoracical vertebrae and 9 lumbar vertebrae). The clinical efficacy, incidence rate of complication, the anterior height of vertebrae body,visual analogue pain scale(VAS) ,ease of pain were measured preoperatively and at 6 weeks, 3 and 6 months and 1 year postoperatively between the two groups. Results All the patients were followed up for 12 -45 months with an average of 23.5 months. The average recovery of anterior height of vertebrae body was respectively(85.95 ± 4.31) % in group A and (93.64 ± 3.35) % in group B,which statistically difference in vertebral height between two groups (P ＜ 0.05). No statistical significant difference was seen in VAS, analgesic durg (AID) and ease of pain complication between two groups (P ＞0. 05). Statistical significant difference was noted in pre-postoperatively between intra-two groups (P ＜0. 05). Conclusions PVP and PKP can quickly relieve pain and enhance vertebral stability in treating thoracolumbar OVCF according to evaluation parameter, and have the similar therapeutic efficacy in treatment of OVCF with minimal invasion. However, PKP is superior in the recovery of vertebral height.

Objective To evaluate thoracic endovascular aortic repair for type B aortic dissection.Methods Chnical data were reviewed on 126 cases with type B aortic dissection undergoing endovascular aortic repair in our hospital from January 2006 to April 2011.There were 86 male patients and 40 female patients,age from 32 to 82 years.The stent- grafts were introduced via femoral arteriotomy.Stent-grafts were implanted to blockade tears of aortic dissection under the guidance of DSA.Postoperatively patients were followed-up by angiography and imiging for endoleak,stent migration,and fracture of stent-graft.Results In all cases,the aortic dissection tears were closed,true lumens were opened,and organ function was restored.There were not complications such as internal hemorrhage due to trauma or stent displacement on CTA from 3 to 63 months after endovascular therapy.Procedure was successful in all 126 cases,157 stents were released,2 cases died in the perioperative period,1 case died during the followed-up.A breach was found at the end of the stent in 12 cases,endovascular aortic repair redone successfully with a retrograde type A dissection found during follow-up.Conclusions Endovascular aortic repair is safe and effective for patients with Stanford type B aortic dissection with a favorable outcomes.
