Objective To assess the effect of thoracoscopic surgery under laryngeal mask anesthesia and explore the nursing strategies. Methods Thirty-five patients from April to December in 2014 undergoing video-assisted thoracoscopic surgery (VATS) were given intubation anesthesia and another thirty-five ones undergoing the same surgery in 2015 received laryngeal mask anesthesia. The two groups were compared in terms of surgery conditions, surgery complication and ambulation time. Results No significant differences were found in surgery time or blood loss between two groups (P>0.05). The postoperative waking time in the mask anesthesia group was significantly shorter than that of the intubation anesthesia group (P<0.05), and ambulation time was significantly shortened (P<0.05). The rates of throat discomfort, hoarseness and gastrointestinal reactions were significantly lower. Conclusions Laryngeal mask anesthesia used in small thoracoscopic surgery for airway management is safe and feasible. Combined with training in respiration and limb function, better analgesia and nursing, it can keep away complications related to intubation anesthesia, shorten hospital stay and accelerate postoperative rehabilitation.

Objective To investigate the impact of surgical resection on patients with Ⅱ-Ⅲ A stage small cell lung carcinoma (SCLC). Method Data of 61 in-patients who diagnosed as Ⅱ-ⅢA stage SCLC from Jan 1st 2009 to Feb 1st 2014 were analyzed. 23 patients underwent surgical resections were enrolled as the treatment group, while 38 patients without surgical resection were enrolled as the control group. Disease progression was confirmed by monthly examination. The grouping is balanced by propensity score match. The progression-free survival (PFS) time and overall survival(OS) were analyzed with Kaplan-Meier survival method and Cox regression is applied to analyze the covariates. Fisher's exact test was applied to compare one-year survival rate and two-year survival rate. Results The PFS and OS of the treatment group is longer than that of the control group (P < 0.05). Both one-year and two-year survival rates of the treatment group outnumber those of the control group (P < 0.05). Cox regression indicates that surgical resection is an independent prognostic factor (P < 0.05). Conclusion Surgical resection on tolerable patients with stage Ⅱ-Ⅲ A small-cell lung carcinoma is effective on improving the progression-free survival time,one-year and two-year survival rates,and also shows a propensity of a higher overall survival time.

Objective To investigate the consistency in 18F-deoxyglucose positron emission tomography (18F-FDG PET-CT) examination and histopathological analyses in the diagnoses of resectable lung tumors. Methods Retrospective reviews over the clinical data of lung tumor patients by preoperative PET-CT diagnosis and postoperative histopathological diagnosis were conducted to investigate the effects of the two diagnostic methods in terms of lung tumor properties , mediastinal lymph node metastasis , and pulmonary hilar lymph node metastasis. Results The diagnoses by preoperative PET-CT was consistent in differentiation of non-malignancy and malignancy of pathologic lung tumors by 87.3%, at a medium level (κ = 0.401, P < 0.001). McNemar test showed P = 0.508, indicating the two diagnostic methods were insignificantly different in the diagnosis of pulmonary tumors. The preoperative PET-CT was consistent in the diagnosis of the metastasis of pathologic mediastinal lymph node by 85.9%, at a medium level (κ = 0.697, P < 0.001). McNemar test showed P =0.754, indicating no significant difference between the diagnostic methods. The preoperative PET-CT was consistent with postoperative pathological examinations in the differentiations of the metastasis of pulmonary and hilar lymph node by 77.4%, at a medium level (κ=0.523, P < 0.001). McNemar test showed P = 0.454, indicating the two diagnostic methods were no significantly different. Conclusion Preoperative PET-CT and histopathologic examinations may be consistent in lung tumor diagnosis , which provides a basis for a certain significance in the surgical options.

Objective To assess the anti-arrhythmic activity and cardioprotective effects of Wenxin Granula, a traditional Chinese formula (consisting of Salviae Miltiorrhizae Radix, Polygonati Rhizoma, Notoginseng Radix et Rhizoma, Nardostachyos Radix et Rhizoma, Angelicae Sinensis Radix, and Succinum), on heart in ischemic-induced myocardial infarction (MI) rats and compare with those of Amiodarone which have been demonstrated in clinic. Methods Rats were randomly divided into Sham-operated (control), Ml + Amiodarone [5 mg/(kg·d)] (MI), and MI + Wenxin Granula [10 mg/(kg·d)] groups and left anterior descending coronary artery was occluded in each group. After left anterior descending for 12 h, standard lead Ⅱ of administration electrocardiogram was recorded in order to analyze the occurrence of arrhythmia. After one month, the size of the infarct area of heart was evaluated by TTC staining method and haemodynamic function was assessed to detect the heart function. Laser scanning confocal microscope and the technique of patch clamp were used to detect the intracellular Ca2+ ([Ca2+]j) and L-type calcium current (ICa-L), respectively. Results Both Wenxin Granula [10 mg/(kg·d)] and Amiodarone [5 mg/(kg·d)] could markedly decrease the incidence of arrhythmia in heart of rats which were subjected to ischemic injury. After one month, Wenxin Granula could significantly decrease mortality to 22.22% and reduce the infarct area (P < 0.05), but Amiodarone did not. The mechanism may involve that Wenxin Granula attenuated [Ca2+]j decreasing in MI rats. Additionally, Wenxin Granula could obviously ameliorate the impaired heart function of MI rats by decreasing the elevated left ventricular end-diastolic pressure and increasing the attenuated maximum change velocity of left ventricular pressure in the isovolumic contraction or relaxation period. On the other hand, electrophysiological experiment results revealed that Wenxin Granula administration one month later also increased the reduced ICa-L density in rat ventricular myocytes in MI rats. The results of LSCM showed that Wenxin Granula could recover the amplitude of [Ca2+]j decreased by heart failure during long term. Conclusion Wenxin Granula could not only inhibit the incidence of arrhythmia but also decrease the mortality, which was accompanied by recovering the amplitude of [Ca2+]j. This protective effect of Wenxin Granula may partially be mediated through changing ICa-L.as well as increasing [Ca2+]j.

OBJECTIVETo compare the complications associated with mechanical and manual cervical esophagogastric anastomosis following esophagectomy for esophageal cancer.

METHODSFrom September, 2004 to June, 2007, 227 patients with middle and upper thoracic esophageal cancer underwent cervical esophagogastric anastomosis after esophagectomy. The patients were randomized into two groups and cervical esophagogastric anastomosis was performed using a stapler (n=102) or manually (n=125). The incidence of postoperative complications and operative time were compared between the two groups.

RESULTSIn manual anastomosis group, anastomotic leak and anastomotic stricture occurred in 14.4% (18/125) and 8.8.% (11/125) of the patients, significantly higher than the incidences of 2.9% (3/102) and 3.9% (4/102) in the mechanical anastomosis group (P<0.01). Manual anastomosis required a significantly longer operative time than mechanical anastomosis (52∓12 vs 25∓5 min, P<0.01).

CONCLUSIONThe use of circular mechanical stapler in cervical esophagogastric anastomosis is associated with a lower rate of anastomotic leak and a shorter operative time, and is easy to learn and standardize to reduce the complications of the anastomosis.

Background and objective Platinum plus a third-generation agent doublet chemotherapy is the stan-dard regimen and ifrst-line chemotherapy for the treatment of advanced non-small cell lung cancer (NSCLC). hTe aim of this study is to evaluate the effcacy and safety of docetaxel plus platinum (DP) compared with vinorelbine plus platinum (VP) regimens in patients with advanced NSCLC. Methods We searched the PubMed, EMBASE, Cochrane Library, CNKI, CBM, VIP, and WanFang databases for randomized controlled trials (RCTs), in which DP regimen was compared with VP regimen. A quality assessment of qualiifed RCTs was performed according to Cochrane Handbook 5.1.0, and Stata 12.0 was used to per-form meta-analysis. Results Seven RCTs involving 2,318 patients were included. Meta-analysis results indicated that the DP regimen increased the two-year survival rate (HR=0.887, 95%CI:0.810-0.972, P=0.010), response rate (RR=1.276, 95%CI:1.107-1.450, P=0.001), and diarrhea rate (RR=3.134, 95%CI:1.918-5.121, P<0.001) compared with the VP regimen. Anemia rate was also reduced (RR=0.386, 95%CI:0.311-0.478, P<0.001). No statistical differences were observed between DP and VP regimens in terms of one-year survival rate, leukopenia, neutropenia, thrombocytopenia, anorexia, nausea, and vomiting. Conclusion DP regimen reduced the rate of anemia and increased the rate of diarrhea, two-year survival rate, and response rate. hTerefore, DP regimen may be a more effective option as a ifrst-line treatment for advanced NSCLC compared with VP regimen.

OBJECTIVETo summarize our experience with video-assisted thoracoscopic (VATS) removal of esophageal leiomyoma located with endoscopy during operation.

METHODSBetween January 2006 and December 2010, 55 patients with esophageal leiomyoma underwent VATS enucleation. The surgical procedure was similar to that of open thoracotomy with intraoperative endoscopic location of the tumor and examination of the mucosal integrity especially for tumors less than 1 cm in diameter.

RESULTSOf the 55 patients undergoing VATS tumor removal, 54 patients completed the procedures smoothly, and 1 patient experienced ventricular fibrillation during the operation to require an open thoracotomy. Endoscopy was used in 38 patients during the operation. VATS enucleation differed significantly from open thoracotomy in the volume of bleeding, postoperative fasting days and postoperative hospital stay (P<0.05). The symptoms were completely relieved after the operation without postoperative complications. The patients were followed up for 8 to 59 months (mean 23.0 months) and no recurrence was found.

CONCLUSIONVATS removal of esophageal leiomyomas is minimally invasive, safe and effective and can serve as the primary option for surgical removal of esophageal leiomyomas.

ObjectiveTo investigate the impacts of portal vein arterializations (PVA) on the liver regeneration in rats with liver cirrhosis.MethodsFifty rats with liver cirrhosis model were randomly divided into PVA group (n=40) and control group (n=10) according to the random number table method. Rats in PVA group underwent PVA+portocaval shunt. Rats in control group received no treatments. The ratio of hepatic wet weight to body weight, the hepatocyte percentage of positive proliferating cell nuclear antigen (PCNA) and hepatocyte percentage in DNA synthesis phase (S phase) in each group were measured at the time of 1 week (T1), 2 weeks (T2), 4 weeks (T3) and 8 weeks (T4) after operation or enrolling in the group. Parameters of every time points inside the group were compared by one-way analysis of variance and pairwise comparison was conducted by LSD-t test. Comparison between groups was conducted byt test.Results The ratio of hepatic wet weight to body weight at T1,T2,T3,T4 in PVA group [(3.72±0.26)%, (3.81±0.27)%, (3.83±0.31)%, (3.78±0.31)%] were signiifcantly increased compared with that in control group [(2.84±0.37)%] (t=6.11,6.64,6.49,6.17;P<0.05). The hepatocyte percentage of positive PCNA at T1, T2, T3, T4 in PVA group [(76±6)%, (69±8)%, (20±5)%, (15±4)% ] were signiifcantly increased compared with that in control group [(11±2)%] (t=34.48, 22.87,5.69,2.93;P<0.05). The hepatocyte percentage of positive PCNA at different time points inside the PVA group decreased gradually as time extended, where signiifcant difference was observed (F=316.20,P<0.05). The hepatocyte percentage in S phase at T1, T2, T3, T4 in PVA group [(27.0±1.2)%, (20.5±1.4)%, (16.2±1.3)%, (13.5±1.3)%] were signiifcantly increased compared with that in control group [(11.6±1.9)%] (t=21.97, 12.15, 6.30, 2.68;P<0.05). The hepatocyte percentage in S phase at different time points inside the PVA group decreased gradually as time extended, where signiifcant difference was observed (F=208.00,P<0.05).ConclusionsPVA can effectively promote liver regeneration in rats with liver cirrhosis and the effect declines as time extends.
