Objective To explore influencing factors of postoperation fast-track recovery in patients with thoracoscopic lobectomy and provide support for the concept of fast track surgery in clinically application. Methods A total of 129 patients who underwent thoracoscopic lobectomy were selected and questionnaire were adopted for survey between January 2015 and September 2015. Univariate analysis and multivariable logistic regression analysis were used to screen influencing factors of postoperation fast-track recovery. Results Univariate analysis showed that the influnecing factors of postoperation fast-track recovery in patients with thoracoscopic lobectomy were closely related to the age, combined basic disease or not,smoking index,preoperative smoking cessation time,preoperative pulmonary function training or not,systematic health education or not,postoperative wound pain,early postoperative ambulation or not,postoperative chest exercises in time or not (t=2.880,χ2=0.219-33.224, P<0.01 or 0.05). Multivariable logistic regression analysis showed that systematic health education or not, postoperative wound pain,preoperative pulmonary function training or not,postoperative chest exercises in time or not,combined basic disease or not,smoking index,and quit smoking more than two weeks or not were the independent risk factors. Conclusions For the patients with thoracoscopic lobectomy, preoperative condition and postoperative condition in the early should be assessed in time. Controlling the pain effectively,giving reasonable guidance of preoperative pulmonary function exercise,strengthening the respiratory tract management,systematic health education,improving the ward environment,high quality of social support and other diversified services could accelerate the recovery of the postoperative patients.

Objective To investigate the esthetic effect of anterior ultra-thin veneers which were fabricated from heat pressed IPS e.max press ingots of high translucency.Methods The whole 62 anterior teeth of 12 patients,who wanted to receive aesthetic restorative treatment,were invloved in the study.Grooves with 0.5 mm depth were marked at the center of the labial face by the use of spherical diamond burs with 1 mm in diameter.At the cervix of the teeth,the design of 0.3 mm shallow concave shoulder was adopted.IPS e.max HT ingots of different color were chosen to be hotpressed; the straining technique was used on the marginal ridge and incisor ridge of the ultra thin veneers after they had been carefully trimmed.Subsequently,the restorations were bonded with Variolink Veneer resin cement.After a short-term follow-up for 3 years,a modified USPHS criterion was used to evaluate the esthetic effect.Results The thickness of the ultra-thin veneers fabricated by heat pressing was 0.3-0.5 mm,marginal integrity of the veneers was perfect and fitted well with the marginal finishing line of the abutment,and then the translucency of veneers was high.There was no edge discoloring after the veneers were used for 6 months to 3 years,and they might produce an excellent chameleon effect by mixing the color of adjacent teeth and gums,and appeared a surface morphology of natural enamel after carefully carved.In the short-term clinical observation,none of the 62 veneers fractured or fell off; there was no case of dentin hypersensitivity.Conclusions Ultra-thin veneers fabricated from IPS e.max Press ingots have the following advantages,a simple operating procedure,high mechanical strength,and satisfactory esthetic effect.

AIM: To evaluate the ability of spectral domain optic coherence tomography ( SD-OCT ) parameters to detect progressive structural damage in primary open angle glaucoma ( POAG) by contrasting with visual field. ·METHODS: Retrospectively we evaluated 48 subjects (48 eyes ) of POAG, followed up 14 to 62mo. The parameters of SD-OCT and visual field were obtained. The correlation between the change of visual field measurements and OCT measurements were analyzed. Visual field progression was defined as reproducible drop of at least 2dB of mean deviation (MD) from the baseline visit. ROC curve was made to evaluated the ability of OCT parameters in detect progression of POAG. ·RESULTS: The 25 eyes were classified in progression group and 23 eyes were in non-progression group. No significant correlation was seen between OCT parameters and visual field in non-progression group. In progression group, OCT parameters which were significantly correlated with MD reduce were rim volume ( r=-0. 5997, P=0. 0007), C/D vertical ratio (r=-0. 6309, P=0. 0003), RNFL(r= 0. 4201, P= 0. 0260), and GCC(r= 0. 7080,P<0. 01). ROC curves showed the GCC reflected the reduce of MD accurately (P=0. 013). ·CONCLUSION: Part parameters of SD-OCT can reflect the progression of POAG accurately and provided a new method to detect the damage of visual function of POAG.

Objective To investigate the clinical value of a new anvil inserting method for esophagogastrostomy or esophagojejunostomy during laparoscopic radical proximal gastrectomy or radical total gastrectomy for gastric cancer.Methods The clinical data of 21 patients with gastric cancer who received laparoscopic radical proximal gastrectomy or radical total gastrectomy at the Southwest Hospital from March 2010 to February 2011 were retrospectively analyzed.Five trocars were inserted through the abdominal wall of the patients.After perigastric lymphadenectomy and mobilization of esophagus,an incision was made on the esophagus above the tumor,and then the anvil with drawn wire attached was inserted into the esophagus.An endo-cutter was applied to cut the esophagus adjacent to the incision left the drawn wire untouched,and then the stem of the anvil was pulled out by the drawn wire for laparoscopic anastomosis. Results The operations were successfully accomplished under the laparoscope with no conversion to open surgery.Fifteen patients received laparoscopic radical total gastrectomy and 6 received laparoscopic radical proximal gastrectomy. The mean operation time,volume of blood loss,time to off-bed activity,passage of flatus and postoperative duration of hospital stay were (257 ± 38) minutes,( 119 ± 32) ml,(2.5 ± 0.5 ) days,( 3.7 ± 0.8 ) days and (7.5 ± 2.6) days,respectively.No perioperative mortality,anastomotic bleeding or anastomotic fistula was detected.One patient was complicated with pulmonary infection + pleural effusion and was cured by conservative treatment; 1 was complicated with anastomotic stenosis which was alleviated by gastroscopic balloon dilation; 1 was complicated by incisional infection and was cured by medical treatment after drainage.No cancer cells were detected at the anastomotic ring or resection margin of the specimen.There were 4 patients with well-differentiated adenoma,8 with moderate-differentiated adenoma and 9 with poor-differentiated mucinous adenoma.There were 5 patients in stage Ⅰ,10 in stage Ⅱ and 6 in stage Ⅲ (UICC staging).Twenty-one patients were followed up for a mean period of (11 ±4) months (range,6-17 months ),no tumor recurrence or metastasis was detected.
