Objective Few studies are reported about the values of the levels of plasma lipoprotein related phospholipase A2 (LP-PLA2) and serum resistin in predicting the prognosis of atherosclerotic cerebral infarction (ACI).This article aims to evaluate the predictive values of LP-PLA2 and serum resistin in the prognosis of ACI.Methods This study included 136 cases of ACI diagnosed and treated in Huaihe Hosptial from September 2013 to September 2014.The patients were followed up for 2 years,during which 48 were found with adverse outcomes (the poor prognosis group) 76 without disease progression (the good prognosis group).We analyzed the influencing factors on prognosis using the Cox proportional hazard model and evaluated the sensitivity and specificity of these factors in predicting the prognostic risks of the patients by ROC curve analysis.Results The rate of poor prognosis was 38.71％ among the included patients.Analysis with the Cox proportional hazard model showed significant impacts of LP-PLA2 (OR =2.105,95％ CI:1.878-2.413) and serum resistin (OR=1.784,95％ CI:1.509-2.213) on the prognosis of the patients.Compared with the good prognosis group,the poor prognosis group exhibited markedly higher levels of LP-PLA2 ([128.78±76.22] vs [268.65±89.02] mg/L,P＜0.01)and serum resistin ([20.71±6.15] vs [24.36±4.87] mg/L,P＜0.01).The sensitivity and specificity of LP-PLA2 combined with serum resistin were 81.35％ and 78.26％,respectively.Conclusion The combination of LP-PLA2 with serum resistin has a good predictive value for the prognosis of atherosclerotic cerebral infarction and is expected to be widely applied as a routine index in clinical practice.

Background: Thymoma is an uncommon tumor without a widely accepted standard care to date. We aimed to investigate the clinicopathologic variables of patients with thymoma and identify possible predictors of survival and recurrence after initial resection. Methods: We retrospectively selected 307 patients with thymoma who underwent complete resection at the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (Beijing, China) between January 2003 and December 2014. The associations of patients' clinical characteristics with prognosis were estimated using Cox regression and Kaplan–Meier survival analyses. Results: During follow-up (median, 86 months; range, 24–160 months), the 5- and 10-year disease-free survival (DFS) rates were 84.0% and 73.0%, respectively, and the 5- and 10-year overall survival (OS) rates were 91.0% and 74.0%, respectively. Masaoka stage (P < 0.001), World Health Organization (WHO) histological classification (P < 0.001), and postoperative radiotherapy after initial resection (P = 0.006) were associated with recurrence (52/307, 16.9%). Multivariate analysis revealed that, after initial resection, WHO histological classification and Masaoka stage were independent predictors of DFS and OS. The pleura (25/52, 48.0%) were the most common site of recurrence, and locoregional recurrence (41/52, 79.0%) was the most common recurrence pattern. The recurrence pattern was an independent predictor of post-recurrence survival. Patients with recurrent thymoma who underwent repeated resec-tion had increased post-recurrence survival rates compared with those who underwent therapies other than surgery (P = 0.017). Conclusions: Masaoka stage and WHO histological classification were independent prognostic factors of thymoma after initial complete resection. The recurrence pattern was an independent predictor of post-recurrence survival. Locoregional recurrence and repeated resection of the recurrent tumor were associated with favorable prognosis.

Objective To delimit the natural infectious focus, including the distribution of wildlife,species, ecology of intermediate hosts and final host of Angiostrongylus cantonensis, as well as the routes of transmission and epidemiological characteristics and wildlife of human Angiostrongylus cantonensis, based on human diverging cases identified in Shenzhen, southern area of China. Methods Data including rate of infection and density of Angiostrongylus cantonensis among different hosts in 12 different areas in Shenzhen was collected, using microscope to inspect homogenate liquids of snails. Wild mice were captured with mouse cage to examine the adult Angiostrongylus cantonensis. Using larva isolated from wild-snails-infected rats to observe the life cycle of Angiostrongylus cantonensis. Results Wild life of Angiostrongylus cantonensis existed in the southwest part of Shenzhen with its majority intermediate hosts as Achatina fulica. The overall rate of infection was 31% in wildlife and final host was found to be Rattus andersoni, Achatina fulica which were extensively distributed in the shrub region of Shenzhen because of suitable climate,humidity and vegetation for generating the life cycle of Achatina fulica. Human infected Angiostrongylus cantonensis was mainly due to eating raw snails or vegetables contaminated by larva of Angiostrongylus cantonensis.The peak of infection was seen from April to November in Shenzhen area.Conclusion Wildlife of Angiostrongylus cantonensis existed in the southwest part of Shenzhen with major wildlife reservoir including fresh water snail and wild mouse. The existence of natural focus Angiostrongylus cantonensis was now recognized as an important source of human angiostrongliasis in Shenzhen area.

OBJECTIVEAn accurate clinical TNM staging of lung cancer is essential for the precise determination of the extent of the disease in order that an optimal therapeutic strategy can be planned. This is especially true in patients with marginally resectable tumors. Clinical over-staging of the disease may deny a patient the benefit of surgery, whereas under-staging may oblige a patient to accept a fruitless or even harmful surgery. We aimed to analyze preoperative clinical (c-TNM) and postoperative surgico-pathologic staging (p-TNM) of lung cancer patients in order to evaluate the accuracy of our clinical staging and its implications on the surgical strategy for lung cancer.

METHODSWe did a retrospective comparison of c-TNM and p-TNM staging of 2007 patients with lung cancer surgically treated from January 1999 to May 2003. Preoperative evaluation and c-TNM staging of all patients were based on physical examination, laboratory studies, routine chest X-ray and CT scan of the chest and upper abdomen. Other examinations included sputum cytology, bronchoscopy, abdominal ultrasonography, bone scintiscan, brain CT/MRI, and mediastinoscopy whenever indicated.

RESULTSIn the present study the comparison of c-TNM and p-TNM staging of 2007 patients with lung cancer revealed an overall concurrence rate of only 39.0%. In the entire series the extent of disease was clinically underestimated in 45.2% and overestimated in 15.8% of the patients. Among all c-TNM stages the c-IA/B stage of 1105 patients gave the highest rate (55.2%) of underestimating the extent of disease. Clinical staging of T subsets was relatively easy with an overall accuracy rate of 72.9%, while that of N subsets was relatively more difficult with an overall accuracy rate of 53.5%. Analysis also showed that c-IV stage may not be an absolute contraindication to surgery, because in half of the patients, c-M1 turned out to be p-M0, providing the possibility of resectional surgery depending on the status of T and N.

CONCLUSIONFor reasons to be further determined, the present preoperative clinical TNM staging of lung cancer remains a crude evaluation. Further efforts to improve its accuracy are needed.

OBJECTIVETo compare the short-term outcomes of surgical treatment for non-small cell lung cancer (NSCLC) by video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT).

METHODSData of 737 consecutive NSCLC patients who underwent surgical treatment for non-small cell lung cancer by video-assisted thoracoscopic surgery and 630 patients who underwent pulmonary resection via open thoracotomy (as controls) in Cancer Institute & Hospital, Chinese Academy of Medical Sciences between January 2009 and August 2011 were retrospectively reviewed. The risk factors after lobectomy were also analyzed.

RESULTSIn the 506 NSCLC patients who received VATS lobectomy, postoperative complications occurred in 13 patients (2.6%) and one patient died of acute respiratory distress syndrome (0.2%). In the 521 patients who received open thoracotomy (OT) lobectomy, postoperative complications occurred in 21 patients (4.0%) and one patient died of pulmonary infection (0.2%). There was no significant difference in the morbidity rate (P > 0.05) and mortality rate (P > 0.05) between the VATS group and OT group. In the 190 patients who received VATS wedge resections, postoperative complications occurred in 3 patients (1.6%). One hundred and nine patients received OT wedge resections. Postoperative complications occurred in 4 patients (3.7%). There were no significant differences for morbidity rate (P = 0.262) between these two groups, and there was no perioperative death in these two groups. Univariate and multivariate analyses demonstrated that age (OR = 1.047, 95%CI: 1.004 - 1.091), history of smoking (OR = 6.374, 95%CI: 2.588 - 15.695) and operation time (OR = 1.418, 95%CI: 1.075 - 1.871) were independent risk factors of postoperative complications.

CONCLUSIONSTo compare with the NSCLC patients who should undergo lobectomy or wedge resection via open thoracotomy, a similar short-term outcome can be achieved via VATS approach.

Objective:To explore the mechanism of resveratrol （RSV） in the treatment of lung adenocarcinoma （LUAD） based on bioinformatics and molecular biology. Method:The targets of RSV were retrieved from DrugBank and then imported into STRING for constructing a protein-protein interaction （PPI） network.TCGA database was utilized to analyze the expression of target genes in tumor and normal tissues， followed by the prediction of their impacts on tumor occurrence and development and the screening of target genes using random forest and univariate Cox regression models.With the results of bioinformatics taken into consideration， the mechanism of RSV in inhibiting LUAD was further explored by molecular biology. Result:Ten Hub genes were screened out from the PPI network of RSV targets.Among them， solute carrier family 2 member 1 （SLC2A1）， arachidonate 5-lipoxygenase （ALOX5）， peroxisome proliferative activated receptor gamma （PPARG）， and arachidonate 15-lipoxygenase （ALOX15） differed significantly in their expression in tumor and normal tissues.As revealed by random forest and univariate COX regression analysis， SLC2A1 was of great significance to the survival and prognosis of patients with LUAD.The survival analysis through Kaplan-Meier （KM） plotter indicated that the SLC2A1 expression was closely related to the overall survival （OS）， first progression （FP）， and post-progression survival （PPS） of LUAD patients.The molecular biological experiments further proved that RSV inhibited the proliferation and migration of LUAD cells by reducing the expression of SLC2A1.As verified by immunohistochemical scoring， SLC2A1 protein expression in tumor tissue was significantly different from that in normal tissue. Conclusion:RSV inhibits the proliferation and migration of LUAD cells by reducing the expression of SLC2A1， which has far-reaching significance in the clinical treatment of LUAD.

Oral mucositis (OM) caused by cancer therapy is the most common adverse reaction in the radiotherapy of head and neck tumors. In severe cases, it can lead to the interruption of treatment, which affects the control of the disease and the quality of life. Shuanghua Baihe Tablet (SBT) is a traditional Chinese medicine (TCM) formula, which is administerd to treat OM in China. It has been clinically effective for more than 30 years, but the underlying mechanism is not completely understood. With the development of multiple omics, it is possible to explore the mechanism of Chinese herbal compound prescriptions. Based on transcriptomics and metabolomics, we explored the underlying mechanism of SBT in the treatment of OM. An OM model of rats was established by 5-FU induction, and SBT was orally administered at dosages of 0.75 and 3 g·kg
