Chongqing Medicine 2015;(22):3082-3083,3087
Objective To observe the effect of bronchial artery infusion chemotherapy in the treatment of central non-small cell lung cancer (central NSCLC)with obstructive pneumonia and its efficacy clinical factors.Methods Retrospective analysis method was applied to the 64 cases of central NSCLC with obstructive pneumonia.All patients were confirmed by pathology.We main contrasted the efficacy between intravenous infusion of antimicrobial agents and bronchial artery infusion chemotherapy (BAI).we focused on the efficacy between treatment group using standard systemic vein chemotherapy/radiotherapy and primary group with no chemotherapy/radiotherapy.Results In control group,the improvement rate was 43.33%.The improvement rate in treatment group was 70.59%.In treatment group,the curing rate was 50.00% for the patients who had ever taken standard sys-temic chemotherapy/radiotherapy.But the curing rate was 88.89% for the primary group.Conclusion For the patients who have the central NSCLC with obstructive pneumonia,intravenous infusion of antimicrobial agents and bronchial artery infusion chemo-therapy (BAI)can obviously increase the curing rate of obstructive pneumonia.
2.Multimodality therapy for adenocarcinoma of the esophagogastric junction.
Chinese Journal of Gastrointestinal Surgery 2012;15(9):877-880
The definition of esophagogastric junction (EGJ) adenocarcinoma and progress in multidisciplinary treatment for the tumor were revised in this review. Siewert classification is especially useful for the surgical approach of EGJ adenocarcinoma. Siewert I should be treated as esophageal cancer, and Ivor-Lewis esophagogastrectomy (right thoracotomy and laparotomy) is recommended as an extended two-field lymphadenectomy. For Siewert II or III tumors, left thoracophreno-laparotomy is preferred, especially in case of positive thoracic lymph nodes or positive resection margin. If there is any contraindication against thoracotomy, or a high operating risk, a transhiatal esophagectomy with lower mediastinal lymphadenectomy is an alternative. Preoperative chemoradiotherapy or perioperative chemotherapy improves overall survival and the rate of complete resection for patients with large tumor or lymph node metastasis. Neoadjuvant chemoradiotherapy is associated with high but acceptable postoperative complications. Adjuvant chemoradiotherapy remains a rational standard therapy for curatively resected EGJ cancer with T3 or greater lesion or positive nodes.

BackgroundThe effects of extremely low frequency electromagnetic fields (ELF-EMFs) on public health have attracted wide attentions.The association of the thermal effect of ELF-EMFs with cancer and ocular tissue damage has been of concern.However,the pathological changes of scleral tissue after exposure to ELF-EMFs as well as the relationship between these changes and myopia are still poorly understood.ObjectiveThe present study was to investigate the molecular pathological changes of human fetal scleral fibroblasts (HFSFs) after exposure to ELF-EMFs in vitro and to explore the possible mechanism in the occurrence and development of myopia.MethodsHFSFs were cultured and passaged and then exposed to 50 Hz electromagnetic fields,and HFSFs that did not receive the irradiation of ELF-EMFs were used as the control group.The expression of collagen type Ⅰ (COL1A1 ) mRNA and matrix metalloproteinase-2 (MMP-2) mRNA in cultured HFSFs were detected by real-time qualitative polymerase chain reaction (real-time PCR) under different magnetic field intensites (0,0.1,0.2,0.5,1.0 mT) and different exposure time (0,6,12,24,36,48 hours).Cell proliferation assay of HFSFs was detected by the cell counting kit 8 ( CCK8 ) assay.The expression levels of COL1 A1 and MMP-2 proteins in HFSFs were further confirmed by immunofluorescence staining.Results The expression of COL1A1 mRNA was significantly down-regulated under the exposure of 0.2 mT ELF-EMFs for 6 hours,in comparison with the control group;moreover,it decreased in parallel with the increased of flux density (0.099±0.008 vs.0.050±0.004) (P =0.009 ).The expression of MMP-2mRNA was up-regulated conspicuously after exposure to 0.1 mT ELF-EMFs for 24 hours,and it increased with exposure time in comparison with the control group ( 0.009 ±0.001 vs.0.018±0.003 ) ( P =0.038 ).Proliferation of HFSFs (A450) was inhibited following the exposure to 0.2 mT ELF-EMFs for 24 hours in comparison with the control group (P =0.009 ).The expression of COL1 A1 in the experimental group was decreased,compared with the control group,but the expression of MMP-2 was increased.ConclusionsELF-EMFs inhibit the proliferation of HFSFs and expression of COL1 A1 in HFSFs,which might be one of the reasons for the development of myopia.

Objective To determine whether thalidomide can maintain remission after discontinuing the treatment of etanercept in ankylosing spondylitis (AS). Methods One hundred and five patients with active AS treated with etanercept 50 rag/week for 12 weeks and attained an ASAS20 response at week 12. They were randomly assigned to receive thalidomide 150mg/night, sulfasalazine (SASP) 2.0 g/d, or non-steroidal anti-inflammatory durgs (NSAIDs) only. All patients were followed monthly for BASDAI, BASFI, PGA and spinal pain VAS. A Kaplan-Meier survival analysis was used to calculate the probability of a relapse. Results One hundred patients completed the follow-up. Thirty patients were treated with thalidomide, 33 patients with SASP and 37 patients with NSAIDs only. The mean follow-up time was 5.1 months and the longest time was 12 months. At the end of the follow-up, the percentage of patients who maintained remission in the thalidomide group was 40%, much higher than SASP group (15%) and NSAIDs group 11% (P=0.0265 and 0.0053 respectively). No difference was found between the remission rate of SASP and NSAIDs only group (P=0.5881). Conclusion Thalidomide can successfully maintain remission of AS after discontinue etanercept treatment.

ObjectiveTo evaluate the efficacy of etanercept in the treatment of active ankylosing spondylitis ( AS) with enthesitis and explore an easy and accurate scoring method.MethodsWe designed this 12-week double-blind,placebo-controlled,randomized clinical study in active AS patients.The first part was a 6-week placebo-controlled period that patients received etanercept or placebo,followed by a 6-week open-label period that all patients received etanercept. At week 0,2,4,6,8,10,12,the scores of enthesitis were recorded.The primary efficacy endpoint was the Mander Index in the two groups. We compared the Maastricht AS Enthesis Score ( MASFS) index,Spondyloarthritis Research Consortium of Canada ( SPARCC) index,Berlin index and San Francisco index with the Mander Index. Results A total of 127 patients were included with 92 in the etanercept group and 35 in the placebo group.In etanercept group there were 25,41,47 patients without enthesitis at week 2,4,6 separately. At week 12,more than 70% patients' enthesitis in two groups turned negative.The primary endpoint,as the Mander Index at week 6,was achieved by 0(0,2) score in the etanercept group compared with 1 (0,3) score in the placebo group (P =0.0286). Among the four Indexes.the San Francisco Index was the one most COrrelated with the Mander Index.Conclusion Etanercept can improve the symptoms of enthesitis fast and significantly. In clinics,the San Francisco Index is easier to operate and more accurate for assessment.

Objective To investigate changes in the expression of apurinic/apyrimidinic endonuclease (APE) and the oxidative DNA damage marker 8 OHdG in distant hippocampus regions of the rat brain after focal cerebral ischemia of the middle cerebral artery.Methods SD rats were divided into the sham surgery group and the pMCAO group (induced by middle cerebral artery occlusion).Pathological changes in brain tissues were examined at 2 h,6 h,12 h,24 h,48 h and 72 h.The expression of APE and 8-OHdG was measured by immunohistochemical staining methods.TUNEL staining was performed to detect apoptosis.Results Reduction of APE expression in the CA1 region of the hippocampus on the ischemia side appeared at 2 h in the pMCAO group and continued as ischemia persisted (F=11.91,P<0.05).The expression of 8OHdG and TUNEL immunoreactivity in the CA1 region of the hippocampus on the ischemia side were first observed at 6h in the pMCAO group and intensified during the remainder of induced ischemia (F=9.23 and 10.46 respectively,P<0.05 for both).Compared with the sham group,8-OHdG expression and TUNEL immunoreactivity in the pMCAO group were at nearly the same levels from 24 h to 72h.Conclusions Oxidative DNA damage occurs in hippocampus regions of the rat brain after experimentally induced focal cerebral ischemia of the middle cerebral artery.APE expression declines in regions distant from focal cerebral ischemia.Development and accumulation of oxidative DNA damage can induce apoptosis in certain brain regions.
