Objective To investigate the indications and clinical efficacy of an exclusive right-thoracic approach in esophageal surgery.Methods The clinical data of 35 patients with esophageal disease who underwent an exclusive right-thoracic approach operation from June 2008 to June 2010 at the Affiliated Hospital of Qingdao University were retrospectively analyzed.Of the 35 patients,21 were with esophageal cancer,and their ages were above 70 years,the partial pressure of oxygen of arterial blood (PaO2),maximal voluntary ventilation and forced vital capacity of the first second were (70 ± 9) mm Hg (1 mm Hg =0.133 kPa),51％ ± 9％ and 57％ ± 11％,respectively.Fourteen patients were with benign esophageal disease or low grade malignancy,and their PaO2 maximal voluntary ventilation and forced vital capacity of the first second were (96 ± 13) mm Hg,83％ ± 11％ and 91％± 14％,respectively.Exclusive right-thoracic approach was selected for all the patients,and surgical procedure was selected according to the location of the lesions.Patients were followed up by out-patient examination or phone call till April 2012.Results All the operations were carried out successfully,21 patients with esophageal cancer underwent partial esophagus resection and stomach-esophagus intrathoracic anastomosis through a right-thoracic approach.Of the 14 patients with benign esophageal disease or low grade malignancy,2 patients were with esophageal leiomyoma,3 with esophageal stromal tumor and 1 with esophageal leiomyomatosis underwent partial esophagus resection + intrathoracic anastomosis ; 7 patients with esophageal leiomyoma and 1 with esophageal stromal tumor underwent tumor extirpation.The operation time and operative blood loss were (3.4 ± 1.8)hours and (160 ± 44)ml,respectively.The number of lymph node dissected of the 21 patients with esophageal tumor was 14 ± 5,including 1.1 ± 0.7 lymph nodes dissected near the left gastric artery.No anastomosis fistula and perioperative death were detected,and the duration of hospital stay was (10 ± 4)days.The postoperative PaO2,maximal voluntary ventilation and forced vital capacity of the first second were (66 ± 10)mm Hg,50％± 11％ and 51％ ± 13％ for patients with esophageal cancer,and (94 ± 13) mm Hg,80％ ± 13％ and 87％ ± 16％ for patients with benign esophageal disease or low grade malignancy.All the patients were followed up for 1-2 years,no eating obstruction was detected,and the postoperative 1-and 2-year survival rate were 82.9％(29/35) and 77.1％ (27/35),respectively.Of the 8 patients with esophageal cancer who died postoperatively,1 died of cardiovascular diseases and 7 died of tumor recurrence and metastasis.Conclusion Exclusive rightthoracic appraoch could be used for patients with benign esophageal disease,low-grade malignancy and old esophageal cancer patients with poor pulmonary function.

Objective:To study the efficacy comparison between the antibacterial catheter and common central venous catheter in ICU patients.Methods: The 110 ICU patients with central venous catheter were randomized into the control group (common central venous catheter)and the observation group (antibacterial catheter), 55 patients per group. The success rate of catheter, the averange catheter days, complications, and the incidence of catheter-related infection (CRI)and pathogen distribution in the two groups were observed and compared.Results: Compared with the control group, the success rate of catheter was significantly increased(100.0% vs 81.8%,x2=11.00,P<0.05), the averange catheter days were obviously reduced(12.5±3.0 vs 13.5±3.0,t=3.49,P<0.05)days, the incidences of complications (red and swelling in puncture site(3.6% vs 27.3%,x2=11.76,P<0.05), fluid in puncutre site (3.6% vs 21.8%,x2=8.18,P<0.05), catheter herniation(1.8% vs 20.0%,x2=9.35,P<0.05)were significantly decreased in the observation group with statistical difference (P<0.05). Conclusion: The antibacterial catheter can significantly reduce the incidence of CRI for ICU patients and improve the security of central venous catheter.

Objective To investigate the suppression effect of RNA interference(RNAi) on the expression of epidermal growth factor receptor(EGFR) of ovarian cancer SKOV3 cell line. Methods SKOV3 cells were transfected with synthetic EGFR sequence-specific dsRNA by lipofectamin 2000.The expression level of EGFR mRNA and protein were detected by RT-PCR and Western blotting,respectively.The proliferation of transfected SKOV3 cells was detected by WST-1 cell proliferation assay.The abilities of adhesion,migration and invasion were detected by cell adhesion assay,cell migration assay and Matrigel invasion assay,respectively. Results The suppression rates on EGFR mRNA and protein by sequence-specific dsRNA-EGFR were 73.65% and 58.94%,respectively.The cell proliferation was inhibited by 22.54%,35.76% and 31.07%,respectively at 24,48 and 72 h after transfection.The adhesion of sequence-specific dsRNA transfected SKOV3 cells for 30 min and 90 min were reduced by 12.11% and 18.66%,respectively.The migration and invasion of SKOV3 cells were decreased by 25.47% and 22.08%,respectively. Conclusion The down-regulation of EGFR expression of ovarian cancer by sequence-specific dsRNA can lead to the suppression of proliferation,adhesion,migration and invasion of ovarian cancer cells.

AIM:To study the changes of tear film and ocular surface after the coaxial incision 2.5mm and 3.0mm in the phacoemulsification.METHODS: Seventy patients (92 eyes) from February 2015 to February 2016 in our hospital were enrolled.The patients were randomly divided into two groups.Thirty-four patients (46 eyes) in Group A: coaxial 2.5mm incision phacoemulsification cataract extraction and intraocular lens(IOL) implantation.Thirty-six patients (46 eyes) in Group B: the conventional coaxial 3.0mm small incision phacoemulsification cataract extraction and IOL implantation.The break up time (BUT),Schirmer`s Ⅰ test (SⅠt) and lid-parallel conjunctival folds (LIPCOF) were assessed preoperatively and postoperatively.RESULTS: At 1wk,1 and 3mo postoperatively,the BUT in two groups decreased after operations,and the BUT of Group B was significantly lower than those of Group A,the differences were statistically significant (t=3.089,4.497,4.322;all P<0.05).The SⅠt in two groups increased after operations,the SⅠt of Group B was significantly higher than those of Group A and the differences were statistically significant (t=-6.286,-3.992,-3.278;all P<0.05).The LIPCOF score in two groups increased after operations,the LIPCOF score of Group B was significantly higher than those of Group A and the differences were statistically significant (t=-6.552,-5.131,-3.652;all P<0.05).At 6mo postoperatively,compared with the preoperative data,the BUT,SⅠt and LIPCOF score in Group A showed no statistically significant differences (t=0.646,0.551,0.165;P>0.05).The BUT,SⅠt and LIPCOF score in Group B showed statistically significant differences (t=-4.059,3.629,4.211;all P<0.05).CONCLUSION: Ocular surface has less damage and tear film has little influence at early stage after the coaxial 2.5mm incision phacoemulsmcation,compared with the conventional coaxial 3.0mm incision phacoemulsification surgery.

The goal of radiologic intervention in patients with membranous or segmental ob struction of inferior vena cava(Budd-Chiari Syndrome)is to relieve the major venous obstruction, control portal hypertension and prevent further hepatocellular damage until collateral hepatic venous outflow channels can develop.Percutaneous balloon angioplasty(PTA)was used to treat 15 patients with this syndrome who were followed up for an average of 30.57?13.57 months(range,8～48 months).In occlusion,PTA can be considered a safe and effective treatment at least patency of one hepatic vein.The therapy is not definitive,multiple treatment are required for the long-term care of the ptients who all hepatic vein are obliterated.
