Objective To investigate the feasibility of combined laparoscopic and thoracoscopic esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity.Methods We retrospectively analyzed the clinical data of 38 patients who underwent esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity from October 2011 to August 2012.To remove the stomach in laparoscopic and the esophagus in thoracoscopy.The main portion of a gastric conduit is created using three to four firings of a linear stapler(Ethicon Endo-surgery,Cincinati,OH) and jejunum stoma.Gastric conduit was pulled into the chest cavity and anastomosed to the esophagus.Results The average operative time was 280 minutes,the mean operative blood loss was 120 ml.No patient required laparotomy.No pulmonary complications or anastomotic leaks occurred.One had gastric retention,another one had chylous hydrothorax.All patients were cured,no one dead in hospital.Conclusion Combined laparoscopic and thoracoscopic esophagectomy for esophageal carcinoma and gastro-esophageal anastomosis in right thoracic cavity is technically feasible and safe,minimized trauma,less operative blood loss and quick recovery.

Objective To measure the costs of primary health services in the community for developing government compensation standard and prediction of budget in 201 5.Methods Literature review and panel discussions were used to build the index database.A two-round Delphi expert consultation determined the work to do and steps for community healthcare standards.60 community health centers were sampled by stratified random sampling for survey,and the work hours,workload and service volume of respective services in 2013 were measured according to the service standards of primary care.Results The community primary care consists of the categories of outpatient services,nursing care, laboratory tests and drug management,totaling 20 services and 88 working procedures.The total work hours of primary healthcare service at 60 community health centers were 2 557 187.9 hours,which is adjusted to 2 959 21 5.1 hours based on workload coefficients.Based on the income standards of employees at the community health centers investigated,and the human cost price which was recommended by the experts,the total costs of primary healthcare of the 60 centers were 245 million,248 million and 318 million respectively,and the average cost was 71.0 yuan,71.8 yuan and 92.1 yuan per visit respectively.By such standards,the government should subsidize 38.9 ~ 60.0 yuan per visit to the centers.The total expenditure of primary healthcare of all communities in Shenzhen in 201 5 was predicted to be 314 to 407 million,for which the government is expected to subsidize 1.68~2.58 billion.Conclusion The subsidies for community primary healthcare fall short as the cost per visit runs up in 2013 to 71.0 yuan per visit or more,far above the current subsidy of 32.1 yuan per person.The subsidy per visit should be made 50.0 yuan in 201 5.

Objective To study the indication,feasibility and short-term efficacy of combined thoracoscopic and laparoscopic radical esophagectomy for the treatment of esophageal cancer.Methods Retrospective medical records analysis was conducted for 139 esophageal cancer patients who underwent combined thoracoscopic and laparoscopic esophagectomy in our department from December 2009 to August 2011.The tumors were located in upper esophagus in 16 cases,middle esophagus in 107 cases,and lower esophagus in 16 cases.The surgery started with the thoracoscopic mobilization of thoracic esophagus and lymph nodes dissection,which were followed by the laparoscopic stomach mobilization and gastroesophageal anastomosis in left neck.Postoperative pathological staging identified stage Ⅰ esophageal cancer in 25 cases ( stage Ⅰ a:13 cases,stage Ⅰ b:12 cases),stage Ⅱ esophageal cancer in 71 cases,stage Ⅲ esophageal cancer in 31 cases ( stage Ⅲ a:16 cases,stage Ⅲ b:15 cases) and stage Ⅳ esophageal cancer in 12 cases.Results Except for open conversions in 4 cases (2.9％),all surgical operations were completed smoothly.Postoperative anastomotic leak was found in 6 cases(4.3％ ),chylothorax in 1 case(0.7％ ),arrhythmia in 4 cases(2.9％ ),and dumping syndrome in 1 case( 0.7％ ).All of these complicated cases fully recovered after conservative treatments.Postoperative lung infection was found 11 cases (7.9％),3 of whom required tracheotomy and assisted ventilation and 1 case died as a result of the infection (mortality rate:0.7％ ).Ten cases(7.2％ ) presented with hoarseness postoperatively.Out of the 139 cases,130 cases were successfully followed up with durations ranged from 1 to 20 months,during of time the esophageal cancer spread to liver in 2 cases,celiac lymph nodes in 4 cases,lung in 2 cases,and bone in 1 case.Ten cases died,and all remaining cases remained alive during the follow up.The one-year survival rate was 88.9％ for these cases.Conclusion Combined thoracoscopic and laparoscopic radical esophagectomy is a technically safe and feasible treatment for esophageal cancer.The short-term efficacy results are satisfactory.This technique is indicated not only for early and middle stage esophageal cancer,but also for some of the advanced esophageal cancer cases.

Objective: To investigate the relationship between hemoglobin levels and prognosis of cerebral infarction in elderly patients aged 75 years and over. Methods: A retrospective analysis of 238 elderly patients (≥75 years old) with cerebral infarction admitted into our hospital from January 2016 to June 2018 was performed. The age, gender, serum creatinine and risk factors for stroke (hypertension, diabetes, dyslipidemia, homocysteine, atrial fibrillation, smoking, drinking), coronary heart disease, previous stroke history, tumor history, National Institutes of Health Stroke Scale (NIHSS) score, hemoglobin, hematocrit and other basic data were recorded. The patients were divided into the group with good prognosis (mRS score ≤ 2) and the group with poor prognosis (mRS score > 2). The relationship between hemoglobin levels and the prognosis of cerebral infarction in elderly patients were analyzed. Results: After 6 months of follow-up, 124 (52.1%, 124/238) stroke patients had a good prognosis, and 114 (47.9%, 114/238) patients had a poor prognosis, including 21 deaths. Anemia at admission (OR=2.433, 95%CI: 1.213-4.591, P=0.011), new-onset anemia after hospitalization (OR=2.615, 95%CI: 1.333-6.521, P=0.043) and the low level of minimum hemoglobin during hospitalization (OR=0.847, 95%CI: 0.671-0.971, P=0.038) were independent risk factors for poor prognosis in elderly stroke patients aged ≥75 years. New-onset anemia after hospitalization (OR=1.015, 95%CI: 1.002-1.027, P=0.022), the low level of minimum hemoglobin during hospitalization (OR=0.801, 95%CI: 0.654-0.981, P=0.027), the decrement of hemoglobin ≥20 g/L (OR=1.342, 95%CI: 1.011-1.763, P=0.000) at reexamination were independent risk factors for the mortality in elderly patients with cerebral infarction. Conclusions Anemia at admission, new-onset anemia after hospitalization, and the low level of minimum hemoglobin during hospitalization are independent predictors for poor prognosis in cerebral infarction patients aged ≥75 years. The decrement of hemoglobin ≥20 g/L after admission is an independent predictor for high mortality in elderly patients with cerebral infarction.

Objective:To analyze the risk factors of fatal outcome in patients with severe COVID-19.Methods:The clinical characteristics of 107 patients with severe COVID-19 admitted in Renmin Hospital of Wuhan University from February 12 to March 12, 2020 were retrospectively analyzed. During the hospitalization 49 patients died (fatal group) and 58 patients survived (survival group). The clinical characteristics, baseline laboratory findings were analyzed using R and Python statistical software. The risk factors of fatal outcome in patients with severe COVID-19 were analyzed with multivariate logistic regression.Results:Univariate analysis showed that the two groups had statistically significant differences in age, clinical classification, dry cough, dyspnea and laboratory test indicators ( P<0.05 or <0.01). The random forest model was used to rank the significance of the statistically significant variables in the univariate analysis, and the selected variables were included in the binary logistic regression model. After stepwise regression analysis, the patient’s clinical type, age, neutrophil count, and the proportion of CD3 cells are independent risk factors for death in severe COVID-19 patients. Dry cough is an independent protective factor for the death of severe COVID-19 patients. Conclusion:COVID-19 patients with fatal outcome are more likely to have suppressed immune function, secondary infection and inflammatory factor storm. These factors may work together in severe patients, leading to intractable hypoxemia and multiple organ dysfunction and resulting in fatal outcome of patients. The study indicates that timely intervention and treatment measures against above factors may be effective to save the lives of patients with severe COVID-19.
