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.

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.

Objective To explore the feasibility of the deep convolutional neural network (DCNN) judging the indications and prognosis of the total knee arthroplasty based on the trained DCNN computer learning system.Methods C1FAR-10 DCNN model based on TensorFlow (an open source system,Google,USA) optimized by Alex Krizhevsky were constructed.There were 400 cases with knee osteoarthritis from different databases used for analysis.Three hundred patients underwent total knee arthroplasty,while 100 did not.X-ray of 200 preoperative cases from the 400 cases and their enlarged image (50 times) were applied for training DCNN,while the enlarged images from other 200 cases were used to test the DCNN.The correlation and the regression between judgment of the DCNN and clinical truth were analyzed.The clinical truths were rechecked three times and were confirmed by treatment results.Pearson correlation and linear regression analysis were used.The relation test of the software was only used as a reference.Results There was no significant difference between the baseline of cases for learning and test.After learning 200 cases,the DCNN judged the 10 000 cases enlarged from remaining 200 cases.The correlation between the DCNN judgment and the clinical truth was not significant (r=0.000,F=0.001,P=0.970).False positive was observed in 1 681 cases,false negative in 3 296.After enlarged to 10 000 images,the correlation between the two judgments was significant (F=11 228.735,P=0.000,r=0.727 and R2=0.529).The software detection precision was 0.860.Conclusion DCNN can be applied in judging the indications of the total knee arthroplasty.Large sample size can improve the accuracy of the judgment significantly.

OBJECTIVE To explore the role of the establishment of the trans-regional review system on rational drug use in second-grade general hospital ，and to promote the rational drug use. METHODS With the administrative support of Jiuquan Health Commission，5 second-grade general hospitals in Jiuquan Medical Association jointly established Jiuquan Rational Drug Use Review Training Center . A trans-regional review system was established to carry out cross-review of prescriptions and medical orders among 5 second-grade general hospitals. Totally 1 500 prescriptions and 900 medical records were collected from 5 second-grade general hospitals before （April to June ，2020）and after （July to September ，2020）the implementation of the project. The changes of rational drug use indicators ，the results of prescriptions and medical order review were investigated before and after the implementation of the project. RESULTS After the implementation of the project ，except for one hospital ，the proportion of drugs in other hospitals decreased to varying degrees with the highest decline rate of 22.56％ . Compared with before the implementation of the project ，reasonable rate of outpatient and emergency prescription review increased by 5.72％ averagely and the reasonable rate of medical order review increased by 10.10％（P＜0.05）. The average utilization rate of antibiotics in outpatients decreased by 14.45％，the average utilization rate of antibiotics in inpatients decreased by 7.98％，and the average use intensity of antibiotics decreased by 25.19％. CONCLUSIONS Through the establishment of trans-regional review system ，medical institutions can be forced to pay more attention to prescription review ，effectively improve the prescription review of pharmacists in medical institutions，and promote the rational use of drugs in medical institutions in the region. However ，there are still some problems ， such as incomplete system coverage ，insufficient work experience ，lagging of informatization ，uneven pharmacist level ，and insufficient assessment and supervision of administrative functional departments.
