Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs)and anti-angio-genic drugs have individually demonstrated clinical benefit in the treatment of patients with advanced non-small cell lung cancer (NSCLC).Recent studies demonstrate that the combination of anti-EGFR and anti-angiogene-sis can more significantly enhance clinical benefit,and even can remit EGFR-TKIs resistance in the treatment of advanced NSCLC.According to the different kinds of anti-angiogenesis drugs,recent clinical studies mainly include the combination of anti-vascular endothelial growth factor monoclonal antibody bevacizumab plus EGFR-TKIs and multi-targeted receptor anti-angiogenic tyrosine kinase inhibitor plus EGFR-TKIs,and the for-mer results show a more significant improvement in terms of safety and efficacy in the treatment of advanced NSCLC.Therefore,the combination of bevacizumab plus EGFR-TKIs can be used as a new treatment standard in the treatment of some patients with NSCLC.

Objective　To explore the significance of the dynamic changes of pro-and anti-inflammatory cytokines in the onset and development of acute panreatitis (AP). Methods　Pro-inflammatory cytokines TNFα, IL-1β, IL-6, and IL-8 and anti-inflammatory cytokines IL-10 and IL-1ra in the plasma of 48 patients with AP and 20 healthy individuals were determined with ELISA. Results　The levels of all pro-and anti-inflammatory cytokines in plasma was significantly higher in AP patients than in control group (P<0.05) in early stage of the disease, and then all levels were decreased gradually, consistent with the alterations of clinical symptoms of the AP patients. Conclusion　The dynamic changes of pro-and anti-inflammatory cytokines might play important role in the onset and development of AP.

Objective To investigate the prevalence of urine abnormalities for school children in Lanzhou and evaluate the signiifcance of urine screening. Methods During 2012-2013, urine from 10795 students were collected, and screened by urine reagent paper. Two weeks later, repeated screening was conducted in those who had abnormal result in the ifrst screening. Children with both results being abnormal were submitted to urine routine tests in local hospitals. Results In the ifrst screening of school children, 1653 (15.31%) children were urinary occult blood positive, 516 (4.78%) had urinary protein, 112 (1.04%) had occult blood with proteinuri and 743 (6.88%) had white cells in urine. In the second urine screening, the positive rate of occult blood was 7.55%(815 ), urinary protein was 2.13%(230), occult blood with proteinuria was 0.69%(74) and white cells in urine was 2.51%(271). Four hundred and iffty-ifve students in 1359 were submitted to urine routine tests. Thirty-two children had pyuria, 147 had hematuria, 23 had proteinuria and 13 had occult blood with proteinuria. Thirteen cases of chronic kidney disease were found in the follow-up. The incidence of urine abnormalities was signiifcantly higher in junior middle school than in primary school. Conclusions Urine screening is an effective way to ifnd asymptomatic kidney disease and urinary tract infection. Follow-up should be strengthened.

Achalasia is an esophageal motility disorder involving the smooth muscle layer of the esophagus and the lower esophageal sphincter. It is characterized by difficulty swallowing, regurgitation, and sometimes chest pain. Peroral endoscopic myotomy (POEM) was developed by Inoue to provide a less invasive permanent treatment for esophageal achalasia. We applied this method to cure successfully a 47-year-old female with achalasia. The procedure was as follows: after creating submucosal tunnel, endoscopic myotomy of circular muscle bundles was carried out at approximately 16 cm in total length ( 15 cm in distal esophagus and 1 cm in cardia). Smooth passing of endoscope through gastroesophageal junction was confirmed at the end of the procedure. The third day after POEM, the barium meal examination revealed the barium smoothly passed though the cardia. The short-term outcome of POEM for achalasia was excellent, and further studies on long-term efficacy and on comparison of POEM with other interventional therapies are awaited.
