Objective     To compare the short-term efficacy and long-term survival of patients with non-small cell lung cancer (NSCLC) treated by uniportal or three portal thoracoscopic radical resection. Methods     A total of 388 patients who underwent uniportal or three portal thoracoscopic radical resection of lung cancer in the Department of Thoracic Surgery of Anhui Chest Hospital from 2015 to 2016 were analyzed retrospectively. The patients were divided into two groups including an uniportal group and a three portal group according to the procedure. The clinicopathological features, perioperative data and long-term survival of the two groups were compared. Results     Finally, we included 205 patients with 105 males and 100 females at an average age of 58.73±10.93 years. There were 102 patients in the uniportal group and 103 patients in the three portal group. There was no statistical difference in clinicopathological features between the two groups (P>0.05). But compared with the three portal group, the uniportal group had less postoperative drainage, shorter postoperative catheterization time and postoperative hospital stay (P<0.05). There was no statistical difference in the number of lymph node dissection stations between the two groups (P=0.058). The pain score at 24 hours after operation in the uniportal group was significantly lower than that in the three portal group (P<0.001). There was no  statistical difference in the total incidence of complications and the incidence of pulmonary complications between the two groups (P=0.161 and P=0.275). The median survival period and the 1st, 3rd, and 5th year survival rate in the uniportal group was 63.0 months and 95.0%, 75.2%, 51.5%, respectively. The median survival period and the 1st, 3rd, and 5th year survival rate in the three portal group was 61.0 months and 89.3%, 70.9%, 50.5%, respectively. There was no satistical difference in the survival results between the two groups (P=0.440). Conclusion     Uniportal thoracoscopic radical resection of lung cancer is more minimally invasive and safe and effective in the treatment of NSCLC. It can make patients recover faster after operation.

Objective:The risk factors for hepatocellular carcinoma (HCC) in hepatitis B virus (HBV)-positive cirrhosis patients were screened based on commonly used laboratory indexes for the purpose of establishing a predictive model and the prediction efficacy of established model was validated in a validation patient cohort.Methods:The clinical data of 661 male patients with HBV-positive cirrhosis (cirrhosis group) and 694 male patients with HBV-positive HCC admitted to the First Hospital of China Medical University from 2010 to 2020 were retrospectively analyzed, age and complete blood count,liver function index (aspartate transaminase/alanine transaminase,glutamine transpeptidase,total protein, prealbumin, total bile acid, total bilirubin,direct bilirubin,cholinesterase), HBV markers, alpha-fetoprotein (AFP), fibrinogen,calcium were compared between the two groups. Multivariate Logistic regression was used to analyze the independent risk factors of HCC. The prediction model of high risk HCC ( P<0.05) was constructed and validated by receiver operating characteristic (ROC) curve and calibration curve. Results:There was significant difference in complete blood count, liver function index, HBV core antibody, HBV core antibody IgM, alpha-fetoprotein, fibrinogen, calcium between the two groups ( P<0.05). Multivariate analysis showed that calcium ( OR=35.770,95% CI 13.39-99.304),HBV core antibody ( OR=0.878,95% CI 0.816-0.944), AFP ( OR=1.002, 95% CI 1.001-1.003), fibrinogen ( OR=1.369, 95% CI 1.202-1.564) were the independent risk factors for HCC ( P<0.05), and were used for the nomogram. The AUC of the nomogram was 0.750 (95% CI 0.720-0.781) and the AUC of the validation group was 0.752 (95% CI 0.705-0.798). Conclusions:Based on calcium, hepatitis B virus core antibody, AFP, fibrinogen, a nomogram of the HCC is established and verified by ROC curve, which could be used to predict the risk of HBV-positive HCC.

Objective:The aim of our study was to compare the short-term and long-term outcomes between minimally invaisive Ivor-Lewis esophagectomy(MIILE)and minimally invasive McKeown esophagectomy(MIME) for squamous cell carcinoma of middle and lower esophagus.Methods:The data of 268 patients diagnosed with middle and lower esophageal spuamous cell carcinoma who had received MIILE or MIME between August 2010 and March 2014 at department of thoracic surgery, The First Affiliated Hospital of University of Science and Technology of China(Anhui Provincial Hospital), was analyzed retrospectively. We divided the subjects into two groups according to the mode of the operation, each group was identified 81 patients after propensity score matching. We were using t test, χ2 test, Kaplan- Meier curve and Log- rank test to compare preoperative data and overall survival of the two groups. Results:Compared with MIME, MIILE had lower complication in pulmonary infection and anastomotic fistula, also had less operating time, whereas MIME had an advantage in the number of lymph nodes dissection adjacent to recurrent laryngeal nerve( P<0.05). The 1-year、3-year、5-year survival rate of MIILE were 87.7%、59.2%、45.9%, and the 1-year、3-year、5-year survival rate of MIME were 86.4%、58.7%、42.8%.There were no significant difference between two groups in 5-year survival rate. Conclusion:For squamous cell carcinoma of middle and lower esophagus, minimally invasive Ivor-Lewis esophagectomy and minimally invasive McKeown have no significant difference in long-term survival, but minimally invasive Ivor-Lewis esophagectomy has advantages in reduce the operating time, decrease pulmonary infection and anastomotic fistula during perioperative period.Nevertheless minimally invasive McKeown has an advantage in dissection of the lymph nodes adjacent to recurrent laryngeal nerve.

Objective The aim of this study was to investigate the effect of microinjection ibudilast on the appendix pain threshold in nucleus accumbens(NAC)of morphine-addicted rats. Methods Normal rats and morphine-addicted rats were injec-ted with ibudilast(5 μg/2 μL)or saline(2 μL)into NAC through glass microelectrode. The tail-flick period(TFL)was used as an in-dicator to observe the thermal pain threshold before and after ibuilast injection. Results After injected ibudilast 5 μg into the NAC of normal rats and morphine-added rats,the TFL was prolonged compared with that before injection,and the TFL prolongation of mor-phine-addicted rats was more significant than that of normal rats. There was no significant change in TFL after 2 μL of saline was in-jected into the NAC of normal rats and morphine-addicted rats. Conclusion Microinjection of ibudilast into NAC of normal rats and morphine-added rats can cause analgesic effect,and the analgesic effect of morphine-addicted rats is more significant.

BACKGROUND: Recently, the detectable rate of ground-glass opacity (GGO ) was significantly increased, a appropriate diagnosis before clinic treatment tends to be important for patients with GGO lesions. The aim of this study is to validate the ability of the mean computed tomography (m-CT) value to predict tumor invasiveness, and compared with other measurements such as Max CT value, GGO size, solid size of GGO and C/T ratio (consolid/tumor ratio, C/T) to find out the best measurement to predict tumor invasiveness. METHODS: A retrospective study was conducted of 129 patients who recieved lobectomy and were pathological confirmed as atypical adenomatous pyperplasia (AAH) or clinical stage Ia lung cance in our center between January 2012 and December 2013. Of those 129 patients, the number of patients of AAH, AIS, AIS and invasive adenocarcinoma were 43, 26, 17 and 43, respectively. We defined AAH and AIS as noninvasive cancer (NC), MIA and invasive adenocarcinoma were categorized as invasive cancer(IC). We used receiver operating characteristic (ROC) curve analysis to compare the ability to predict tumor invasiveness between m-CT value, consolidation/tumor ratio, tumor size and solid size of tumor. Multiple logistic regression analyses were performed to determine the independent variables for prediction of pathologic more invasive lung cancer. RESULTS: 129 patients were enrolled in our study (59 male and 70 female), the patients were a median age of (62.0±8.6) years (range, 44 to 82 years). The two groups were similar in terms of age, sex, differentiation (P>0.05). ROC curve analysis was performed to determine the appropriate cutoff value and area under the cure (AUC). The cutoff value of solid tumor size, tumor size, C/T ratio, m-CT value and Max CT value were 9.4 mm, 15.3 mm, 47.5%, -469.0 HU and -35.0 HU, respectively. The AUC of those variate were 0.89, 0.79, 0.82, 0.90, 0.85, respectively. When compared the clinical and radiologic data between two groups, we found the IC group was strongly associated with a high m-CT value, high Max CT value, high C/T ratio and large tumor size. Gender, solid tumor size, tumor size, C/T ratio, m-CT value and MaxCT value were selected factor for multivariate analysis, when using the preoperatively determined variables to predict the tumor invasiveness, revealed that tumor size, C/T ratio, m-CT value and Max CT value were independent predictive factors of IC. CONCLUSIONS The musurements of Max CT value, GGO size, solid size of GGO and C/T ratio were significantly correlated with tumor invasiveness, and the evaluation of m-CT value is most useful musurement in predicting more invasive lung cancer.

BACKGROUND: Through the comparative analysis of the acute and chronic pain postoperative between the single port and triple port video-assisted thoracic surgery to seek the better method which can reduce the incidence of acute and chronic pain in patients with lung cancer. METHODS: Data of 232 patients who underwent single port -VATS (n=131) or triple port VATS (n=101) for non-small cell lung cancer (NSCLC) on January 1, 2016 to June 30, 2017 in our hospital were analyzed. The clinical and operative data were assessed, numeric rating scale (NRS) was used to evaluate the mean pain score on the 1th, 2th, 3th, 7th, 14th days, 3th months and 6th months postoperative. RESULTS: Both groups were similar in clinical characteristics, there were no perioperative death in two groups. In the 1th, 2th, 7th, 14th days and 3th, 6th months postoperative, the NRS score of the single port group was superior, and the difference was significant compared with the triple port (P<0.05). There was no statistically significant difference between the two groups in operative time, blood loss, postoperative hospitalization time, duration of chest tube, the NRS scores in the 3 d (P>0.05). Univariate and multivariate analysis of the occurrence on the chronic pain showed that the operation time, surgical procedure and the 14th NRS score were risk factors for chronic pain (P<0.05). CONCLUSIONS The single port thoracoscopic surgery has an advantage in the incidence of acute and chronic pain in patients with non-small cell lung cancer. Shorter operative time can reduce the occurrence of chronic pain. The 14th day NRS score is a risk factor for chronic pain postoperative.

Objective:To analyze the short-and long-term outcomes of elderly patients after esophagectomy by comparing preopera-tive comorbidities, postoperative complications, and survival rates among different age groups. Methods:We retrospectively reviewed the data of 253 patients who underwent esophagectomy from January to December 2010 in The First Affiliated Hospital of University of Science and Technology of China. Eighty-eight (34.8％) patients were aged<60 years (group A), 145 (57.3％) were aged 60-75 years (group B), and 20 (7.9％) were aged≥75 years (group C). The short-and long-term outcomes of the patients were analyzed. Results:There were significant differences in three group of patients with hypertension before operation (P<0.05). There were statistically sig-nificant differences among all complications, major complications, pulmonary infection, arrhythmia, and respiratory insufficiency (P<0.05), except for anastomotic leakage and other complications (P>0.05). The mean follow-up was 50.7 months. The median overall sur-vival and 1-, 3-, and 5-year overall survival rates were 68 months and 98.9％, 86.8％, and 69％, respectively, for group A;61 months and 93.1％, 76.1％, and 51％, respectively, for group B;and 32 months and 63.3％, 46％, and 28.8％, respectively, for group C (P<0.001). The median progression-free survival (PFS) and 1-, 3-, and 5-year PFS rates were 60 months and 98.86％, 85.2％, and 45.5％, respectively, for group A;43 months and 87.6％, 53.1％, and 26.9％, respectively, for group B;and 11 months and 30％, 20％, and 10％, respectively, for group C (P<0.001). The differences in survival rates between groups A and B, A and C, and B and C were statistically significant (P<0.001). The multivariate analysis showed that age and TNM stage IV were independent risk factors for overall survival and PFS (P<0.05). Conclusions:The long-term survival rate decreases significantly in elderly patients with esophageal cancer. In addition, age and advanced pathological stage of tumor are independent risk factors for long-term outcomes.

BACKGROUND: Currently, there are many reports on the advantages of three portal video-assisted thoracic surgery (VATS) in the treatment of lung cancer, but there are few reports on the comparison between uniportal and three portal video-assisted thoracic surgery. In this study, we aimed to evaluate the recent curative effect of the postoperative short-term quality of life between uniportal and three portal video-assisted thoracic surgery for non-small cell lung cancer. METHODS: We retrospectively evaluated 266 patients with NSCLC who underwent intended VATS lobectomy by a single surgical team in our ward between January 2016 and August 2017. The general clinical date, perioperative data and short-term life quality were individually compared and analyzed between the two groups. RESULTS: The two groups were similar in terms of clinicopathological features, total number of dissected lymph nodes and nodal stations, postoperative complications and pulmonary complications (P>0.05). Compared with three portal VATS, the intraoperative blood loss, chest tube duration, postoperative thoracic drainage, length of stay and NRS score were significantly decreased in uniportal VATS, with significant differences (P<0.05). CONCLUSIONS As a more minimally invasive surgery, uniportal VATS can be safely and effectively performed for resectable lung cancer, which would achieve even better operation curative effect than three portal VATS.

BACKGROUND: Previous studies have shown that the neutrophil-to-lymphocyte ratio (NLR) has a significant impact on the prognosis of many malignant tumors such as gastric cancer, colorectal cancer and pancreatic cancer, but the study on the prognosis of patients with resectable lung adenocarcinoma is less. The aim of this study is to investigate the correlation between the NLR and the clinicopathologic features of adenocarcinoma of lung patients who underwent radical pneumonectomy. Furthermore, this study aimed to clarify the predictive and prognostic significance of NLR in patients who underwent pneumonectomy for lung adenocarcinoma. METHODS: This study reviewed the medical records of 163 patients with lung adenocarcinoma who underwent pneumonectomy. The receiver operating characteristic (ROC) curve and Youden index were used to determine the cut-off value of the NLR. Survival curves were described by Kaplan-Meier method and compared by Log-rank test. The univariate and multivariate analyses were performed with the Cox proportional hazard model to identify the prognostic factors. RESULTS: When the NLR value was 2.96, the Youden index was maximal, with a sensitivity of 77.5% and a specificity of 75.9%. The 5-year survival rate in the low NLR group was higher than that in the high NLR group (P<0.05). The univariate and multivariate analyses showed that TNM staging and NLR were independent factors in predicting survival rate. CONCLUSIONS The NLR value was a simple and useful tool to predict the prognosis of lung adenocarcinoma after radical pneumonectomy.
