Objective To investigate the difference of lung and target volume and dosimetry characteristics features of deep inhalation breathing holding-active breathing control (ABC) and the four dimensional CT (4D-CT) free breathing in stereotactic body radiation therapy (SBRT) technology for patients with lung cancer.Methods 10 patients with pulmonary malignant tumor who were proposed SBRT treatment were selected,and received CT under free breath (FB-CT),4D-CT scan under quiet respiration (4D-CT) and active breathing control CT scan (ABC-CT),respectively.With SBRT technology under the same condition designed four corresponding plans,FB-CT,ABC-CT,4D-CT and 4D-CT0 which was the end inspiratory phase of 4D-CT respectively.The lung volume(V),PTV,V5,V20,mean lung dose(MLD) and normal tissue complication probability(NTCP) of four treatment programs were counted and compared.Results Compared with FB-CT,V,PTV,V5,V20,MLD and NTCP of ABC-CT were 51.48％,-65.34％,-42.64％,-56.62％,-40.22％ and-98.53％ (t=-7.14 to6.16,P＜0.05);PTV,V5,V20,MLD and NTCP of 4D-CT were-40.14％,-16.90％,-37.16％,-17.85％ and-90.96％ (t =0.54 to 3.22,P＜0.05);PTV,V5,V20,MLD and NTCP of 4D-CT0 were-68.98％,-30.21％,-48.49％,-37.45％ and-95.82％ (t=1.32 to 5.46,P＜0.05),respectively.Compared with FB-CT,the lung volume of 4D-CT and 4D-CT0 had no statistical difference (P ＞ 0.05).Conclusions ABC-CT methods have ideal clinical characteristics,with larger double lung volume,smaller artifacts of image,and higher target matching precision.ABC-CT methods reduce the dose of normal lung tissues significantly.

OBJECTIVE: To investigate the expression and clinical significance of BUB1 protein in laryngeal squa mous cell carcinoma (LSCC) tissues. METHOD: The expression of BUB1 protein was measured by immunohistochemistry (EliVision two steps) in 55 cases of LSCC tissues,30 cases of adjacent normal laryngeal mucosa tissues, the relationship of BUB1 expression with clinical pathologic factors in LSCC was also analyzed. RESULT: The positive rate of BUB1 protein in LSCC tissues (50.9%, 28/55) was significantly lower than that in adjacent normal laryngeal mucosa tissues (83.3%, 25/30), P < 0.01. The positive rate of BUB1 protein was correlated with differentiation grading and lymph node metastasis of LSCC (P < 0.05, respectively), but not with patient's sex, age, smoking, tumor site, T-stage and clinical stage(P > 0.05, respectively). CONCLUSION The low expresssion of BUB1 protein is closely related to the tumorigenesis and development of LSCC, and can be a molecular marker for prognosticating metastasis and prognosis of LSCC.

Gallbladder carcinoma (GBC) is often obscured by some benign diseases in clinical practice and thus unsuspected GBC tends to occur.As for etiology,long-term stimulation by gallstones,gallbladder polyps larger than 1 cm,gallbladder adenoma,and adenomyomatosis of the gallbladder are closely associated with GBC.In the aspect of molecular biology,long non-coding RNA,microRNA,surface growth factor receptor,and some membrane proteins are involved in the development and progression of GBC,which may provide a reference for clinical practice.It is of great importance to perform intraoperative and postoperative surgical management of GBC,which is related to patients'survival.Patients with highly suspected or proven GBC should be converted to open surgery after disease assessment,in order to avoid reoperation.Reoperation should be performed for patients with unsuspected GBC found by postoperative pathological examination,in order to avoid tumor progression and metastasis.

ObjectiveTo explore the effect of endovascular treatment for closed limb artery trauma. MethodsFrom March 2006 to December 2011,the clinical data of 12 cases treated for closed limb artery trauma were analyzed retrospectively.Catheters sheath were placed by antegrade or retrograde puncture.Catheters was send to the proximal end of the lesion.Intraoperatively through angiography the location and extent of arterial lesions were determined.Catheter with the help of guidewire were sent through the lesion to establish treatment “ pathway,at the lesion site suitable stents were placed to repair damaged arteries. ResultsThe procedure was all successful in 12 patients,there was no mortality nor sever compalications.Postoperatively 2 cases suffered from acute renal failure,and were managed and cured by continuous veno-venous hemofiltration (CWH).Osteofascial compartment incision decompression was carried out in 3 cases due to osteofascial compartment syndrome.One case of them suffered from amputation due to sever muscle necrosis and lost of limb function.Eleven patients were followed-up for 1year.All the arteries were patent.There were no stent break,deformation or stenosis.ConclusionsEndovascular techniques for the treatment of closed limb arterial trauma is safe and effective.

BACKGROUND: Percutaneous vertebroplasty (PVP) is usually used for osteoporotic thoracolumbar fractures,which has various advantages such as easy to operate, short operation time, less trauma, rapid recovery,analgesic effect and so on. But its application is restricted due to nerve compression symptoms and pulmonary embolism caused by bone cement leakage. Thereafter, how to reduce the leakage of bone cement is an issue of concern.OBJECTIVE: To investigate the relationship between the lumbar quantitative computed tomography (QCT) values and contrast agent dispersion in osteoporotic thoracolumbar fractures. METHODS: Sixty cases of osteoporotic thoracolumbar fractures undergoing PVP were enrolled, and received QCT examination before surgery, and contrast agent was injected intraoperatively. X-ray examination was conducted to detect the bone mineral density, contrast agent dispersion and leakage of bone cement, and the relationship between the lumbar QCT values and contrast agent dispersion as well as leakage of bone cement.RESULTS AND CONCLUSION: (1) There were 110 vertebral fractures, and 74 vertebrae with contrast agent diffusing more than vertebral midline, accounting for 67.3%. There was significant difference in the contrast agent dispersion among groups (P < 0.05). (2) The bone cement leakage showed no significant difference among groups after injected with bone cement by unilateral or bilateral approach (P > 0.05). (3) These results suggest that contrast agent dispersion in osteoporotic thoracolumbar fractures has a certain relationship with the lumbar QCT values, and lumbar QCT values with more contrast agent dispersion, but the lumbar QCT values have no correlation with bone cement leakage. Therefore, choosing a appropriate approach based on the QCT values and contrast agent dispersion can reduce leakage and improve the safety of PVP.

Objective To investigate the safety and feasibility of robot assisted laparoscopic precise enucleation for complex central located renal hilum tumors.Methods From July 2017 to October 2018,a single surgeon completed seven robot assisted laparoscopic precise enucleations for complex central located renal hilum tumors.There were five males and two females with an average age of 56.5 years (45-68 years),an average body mass index of 25.1 kg/m2 (19.8-29.2 kg/m2),four cases on the left side and three cases on the right side.The average tumor diameter was 3.5 cm,ranging(2.2-4.5 cm).The R.E.N.A.L.score was 9.7 (9-11).The average preoperative GFR was 44.5 ml/min (36.5-51.7 ml/min).The surgery was completed step by step as follow:the renal hilum was fully dissociated.The arteries,veins and collective system were completely freed.After blocking the renal artery,the renal hilum was completely dissected again.The tumor was enucleated precisely,and the wound was given a point-to-point suture.Results All operation were completed safely and successfully without conversion to nephrectomy and open surgery.The average operative duration was 175.0 min (133-224 min).The average warm ischemia time was 27.3 min (22-38 min) and the intraoperative blood loss was 155.7 ml (50-250 ml).One patient had gross hematuria after surgery.Postoperative pathology showed clear cell carcinoma and the margins were negative.After three months,the average GFR was 29.3 ml/min (23.9-33.2 ml/min).There was no tumor recurrence and metastasis.Conclusions Robot assisted laparoscopic precise enucleation is a safe and feasible surgery for complex central located renal hilum tumors,and it is worth further promotion.
