BACKGROUNDTo analyze the perioperative respiratory and circulatory features of overweighted patients with lung cancer.

METHODSThe perioperative respiratory and circulatory features of 221 overweighted lung cancer patients were compared with those of 715 normal-weighted patients, by means of Chi-square analysis and t analysis.

RESULTSThe abnormal incidence of MBB, Raw, SGaw, PEF, FEV₁, V₇₅ , and EEG, blood presure, serum cholesterol and glucose, was significantly higher in overweighted group than that in the normal weighted group ( P < 0.05), and FRC was significantly lower than that of the normal weighted group (3.46±0.87 vs 3.63±1.17, P < 0.01). There was no difference in D LCO, MMEF, V₅₀ , V₂₅ between the two groups. The odds of postoperative complication in respiratory or circulatory system was significantly increased in overweighted group than that in the normal weighted group.

CONCLUSIONSThe obstruction of main airway, partial alveolar collapse and impotency of respiratory muscle may result in respiratory complication in overweighted patients, and increased cardiac burden and some pre-existing diseases in overweighted patients might be the cause of increased incidence of circulatory complication.

BACKGROUNDTo investigate the diagnosis and treatment of pulmonary sclerosing hemangioma (PSH).

METHODSThe clinical features, radiographic manifestations and treatment of 21 patients with PSH were reviewed.

RESULTSNone of the 21 patients was diagnosed as PSH preoperatively. There were 18 females and 3 males, and the average age was 48.0 years in this group. Twelve patients were symptom free. The plain chest roentgenograms showed a well defined, homogeneous, round or oval nodulous shadow in most cases. All patients received operation. There was no postoperative morbidity and mortality. Postoperative follow-up showed a good prognosis.

CONCLUSIONSPreoperative diagnosis of PSH is quite difficult. PSH should be suspected in middle to old aged female patients who show a well defined, homogeneous, round or oval shadow in plain chest roentgenograms. PSH has a good prognosis if it is treated surgically.

BACKGROUNDTo investigate the role of curative and palliative surgical treatment of lung cancer with video-assisted thoracoscopic surgery (VATS).

METHODSForty-three patients with lung cancer were prescribed operations with VATS, which included 5 cases of stage IA, 14 cases of IB, 1 case of IIA, 4 cases of IIB, 7 cases of IIIA, 6 cases of T4-IIIB and 6 cases of IV. The 7 patients of stage IIIA were previously staged as N0 before operation, but reevaluated as N2-IIIA after operation. There were 3 cases of malignant pleural effusion and 3 cases of pleural implantation in stage IIIB cases. There were 2 cases of cardiac tamponade, 1 case of solitary brain metastasis, and 3 cases of ipsilateral or contralateral solitary lung metastasis in cases of stage IV. The main methods of operation performed included lobectomy in 36 cases, wedge resection in 5 cases, and pericardial opening in 2 cases. Systemly mediastinal lymph node dissections were performed in 36 cases. Concurrent contralateral pulmonary wedge resections were performed in 2 cases of contralateral solitary lung metastasis. Malignant pleural effusions were prescribed resection of implantation nodules, electrocautery and pleurodesis.

RESULTSThere was no perioperative death or bronchial leak. Five cases suffered lung infection, and 2 cases occurred with incision infection. Malignant pleural effusion in the 3 cases was controlled satisfactorily. Two cases of pericardial opening died in 4 months and 8 months after operation respectively. The other patients were alive till present. Postoperative hospital stay was 5-15 days with average of 7.4 days, except of two cases of pericardial opening.

CONCLUSIONSVATS is an alternative way for complete resection of early stage lung cancer. It is technically feasible to dissect mediastinal lymph node for accidental N2 lung cancer. VATS has significant advantage in concurrent bilateral pulmonary resection. The palliative operation of malignant pleural effusion and cardiac tamponade by VATS can markedly improve the quality of life of patients.

OBJECTIVE: To investigate the structural abnormalities of brain in patients with antisocial personality disorder (ASPD) but without alcoholism and drug abuse. METHODS: Volunteers from Hunan Reformatory (n=36) and the matched healthy subjects (n=26) were examined by high-spatial resolution magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI). Voxel-based morphometry and fractional anisotropy (FA) maps were generated for each subject to reveal structural abnormalities in patients with ASPD. RESULTS: Compared with the healthy controls, ASPD patients showed significantly higher gray matter volumes in the inferior parietal lobule (P≤0.001, uncorrected), white matter volumes in the precuneus (P≤0.001, uncorrected), FA in the left lingual gyrus, bilateral precuneus, right superior frontal gyrus and right middle temporal gyrus (P≤0.01, uncorrected). CONCLUSION Our results revealed the abnormal neuroanatomical features in ASPD patients, which might be related to the external behavioral traits in ASPD patients.

Objective: To investigate the effects CXCL1 derived from TAMs on the progression of HCC by CXCL1 in tumor microenvironment (TME) ． Methods : PMA induced human monocyte (THP-1) to obtain undifferentiated macrophages (M0) and then co-cultured with Huh 7 HCC cells．The biomarkers of macrophage phenotype and mRNA level of HCC were analysed by qRT-PCR. Colony formation assay，cell viability assay and transwell assay were performed to evaluate the biological alteration of HCC cells in TME．Epithelial-mesenchymal transition (EMT) molecular genetics were detected using western blot．The levels of CXCL1 in TME were measured by ELISA assay. Results : High CXCL1 expression in HCC patients predicted poor prognosis．Abundant macrophages were found in CXCL1 high expression HCC tissues．In macrophages and HCC co-cultured model，significantly increasing CXCL1 expression was detected in both two cells and the biomarkers of M2 macrophages，CD163 and CD206 were elevated．The growth and migration of HCC cells were promoted． Conclusion Co-culture of macrophages with HCC cells induces macrophages pro-tumor phenotype and CXCL1 secretion which promotes the progression of HCC.
