Objective To evaluate the short?term efficacy and safety of endoscopic photodynamic therapy ( PDT ) for esophageal squamous cell carcinoma ( ESCC ) and precancerous lesion. Methods Retrospective analysis was performed on 30 patients with early ESCC or precancerous lesions who received PDT between September 2013 and April 2015 in Endoscopy Center, Henan Tumor Hospital,and its indications were summarized. The main outcomes including histological complete response rate ( CR ) , recurrence rate and adverse events after treatment of one year were analyzed. Results Three patients with middle grade dysplasia( MGD) , 18 with high grade dysplasia( HGD) and 4 with squamous cell carcinoma in situ, all negative lymph node metastasis, received PDT. CRs were 72?0%(18/25) and 88?0%(22/25)after one PDT session in 3 months and 12 months, respectively. One?year follow?up showed 3 recurrences ( 12?0%) ,4 ( 16?0%) severe strictures, and no perforation. Five patients with advanced squamous cell carcinoma received palliative PDT. Partial remission rate was 60?0%( 3/5) after one PDT session in 3 months, and 40?0% ( 2/5) after 12 months. Two died of tumor metastasis, one died of gastrointestinal bleeding one year after PDT. No perforation occurred. Conclusion Endoscopic photodynamic therapy for esophageal squamous cell carcinoma and precancerous lesions is safe and feasible, with remarkable short?term effect. As for the patients with advanced squamous cell carcinoma, it is equally safe and effective in the short term.

Purpose To explore the independent predictors of malignant solitary pulmonary nodule (SPN) manifesting as ground-glass nodule (GGN),and to establish a prediction model.Materials and Methods The clinical data and CT images of 362 patients (group A) with pathological-confirmed SPN appearing as GGN in Shanghai Chest Hospital Shanghai Jiaotong University from January 2014 to December 2015 were retrospectively analyzed.The independent predictors of malignant SPN were identified,and the clinical prediction model was established.Another 119 SPN patients in Affiliated Zhoushan Hospital of Wenzhou Medical University were selected as group B to verify the diagnostic efficiency of the prediction model.Results Using multivariate Logistic regression analysis,clear border (OR=6.274,P<0.01),smooth edge (OR=0.391,P<0.01),lobulation (OR=3.387,P<0.01),pleural retraction sign (OR=2.430,P<0.01),and vocule sign (OR=3.076,P<0.01)were identified as independent predictors of malignant SPN.The area of the model under the ROC curve was 0.859 with 95% CI (0.804-0.903).The diagnostic accuracy rate,sensitivity,specificity,positive predictive value and negative predictive value were 85.92%,91.03%,81.97%,92.03% and 73.53%,respectively.Conclusion In this study,the independent predictors of malignant SPN appearing as GGN were identified,and the prediction model was established.The model can accurately identify SPN and provide effective help for early diagnosis of SPN.

Objective:To analyze any changes in the functional connectivity between the seed points of the dorsolateral prefrontal cortex (DLPFC) and the whole brain, as well as any fluctuations in the low-frequency amplitude among persons with post-stroke depression (PSD). The aim was to develop correlations among functional imaging results, clinical scales, and inflammation indicators including high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), interleukin 2 (IL-2), interleukin 10 (IL-10), interleukin 17a (IL-17a) and interferon-γ (IFN-γ).Methods:Between 2016 and 2020, 55 ischemic stroke survivors were tested. The 28 scoring 7 or more on the Hamilton Depression Scale (HAMD-17) formed the PSD group, while the 27 others formed the control group. Functional magnetic resonance images were collected, and serum inflammation indicators were determined.Results:When seed points in the left DLPFC were used, in the PSD group the frontal cortex (FC) decreased in one cluster, with a voxel of 129mm3 and the MNI coordinates (x=9, y=30, z=33) indicating that the anatomical automatic labeling (AAL) brain regions were the Cingulum_Ant_L, Cingulum_Mid_R and the frontal_Sup_Medial_L. When the right DLPFC was used as the seed point the FC again decreased in one cluster, with voxels of 44mm 3 and the MNI coordinates (x=-27, y=12, z=47) referring to the AAL brain region of the frontal_Mid_L. In the PSD group, the FC value of abnormal brain areas with the R-DLPFC as the seed point was positively correlated with time since stroke. In the control group, the FC value of abnormal brain areas with L-DLPFC as the seed point was negatively correlated with MoCA, while with R-DLPFC as the seed point it was positively correlated with IFN-γ. The FC values of abnormal areas of the brain showed no significant correlation with other clinical scales, inflammation indicators or lesion volume. Conclusion:Abnormal functional connections within the executive control network and between the salience networks may participate in the mechanism of PSD, and may be related to the time since stroke, cognitive functioning, and IFN-γ levels.

OBJECTIVETo investigate the feasibility of no nasogastric intubation and early oral feeding at will after thoracolaparoscopic esophagectomy for patients with esophageal cancer.
METHODSBetween January 2013 and January 2014, the feasibility of no nasogastric intubation and early oral feeding at postoperative day(POD) 1 after thoracolaparoscopic esophagectomy was prospectively investigated in 156 patients (trial group) with esophageal cancer in the Henan Cancer Hospital. One hundred and sixty patients previously managed in the same unit who were treated routinely after thoracolaparoscopic esophagectomy were served as control group.
RESULTSOf 156 patients of trial group, 6(3.8%) patients could not take food early as planned because of postoperative complications. The overall complication rate in trial group was 19.2%(30/156), which was 25.0%(30/160) in control group (P=0.217). The anastomotic leakage in trial group and control group was 2.6%(4/156) and 4.3%(7/160) respectively (P=0.380). Compared with control group, time to first flatus [(2.1±0.9) d vs. (3.3±1.1) d, P<0.001], bowel movement [(4.4±1.3) d vs. (6.6±1.0) d, P<0.001] and postoperative hospital stay [(8.3±3.2) d vs. (10.4±3.6) d, P<0.001] were significantly shorter in trial group.
CONCLUSIONSNo nasogastric intubation and early oral feeding postoperatively in patients with thoracolaparoscopic esophagectomy is feasible and safe. This management can shorten postoperative hospital stay and fasten postoperative bowel function recovery.

Objective To describe the effects of surgical intervention on the prognosis in non-small-cell lung cancer patients with pleural carcinomatosis detected at thoracotomy.Methods Retrospectively analyzed clinical data from 54 patients who have unexpected malignant pleural nodules and/or malignant pleural effusions first detected at thoracotomy from January 2009 and December 2013.The effects of surgical intervention on the prognosis were also discussed.Results Sixteen cases had only biopsy,whereas 38 (70.4%) cases had primary tumor resection.The median survival time of 54 patients with pleural carcinomatosis were 23 months.The overall 1 and 5-year survival rates were 64% and 18%,respectively.Primary tumor resection had significantly better outcome compared with biopsy(MST:respectively,24 vs 15 months,5-year survival rate 39% vs 6%,P <0.05).Univariate analysis showed that primary tumor resection,no smoking history,lower T and N stage has favorable survival(P < 0.05).Multivariate analysis showed that the best N stage(P =0.002) and adenocarcinoma(P =0.035) were favorable prognostic factors in these patients.Conclusion For patients with pleural careinomatosis first detected at thoracotomy,limited primary tumor resection may have survival benefits,lower T and N stage for them was associated with better survival.
