Chemotherapy is still the main treatment in advanced gastric cancer by now,but no standard approach has been adopted.Chemotherapy can prolong median overall survival and improve quality of life compared to the best supportive care alone.Recent years,with the appearance of various new agents,chemotherapy remains continuous improvement.As a result,response rate and overall survival of advanced gastric cancers were further improved.Meanwhile,with a greater understanding of the molecular biology of gastric cancer,molecular biological targeted therapies that target human epidermal growth factor receptor 2 (HER-2),endothelial growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) become the focus of the comprehensive treatment.Chemotherapy combined targeted therapy have shown great benefit and perspective in treatment of advanced gastric cancer,but their usage should be further modified and optimized in clinical trials and practices.

OBJECTIVE To investigate the distribution and drug resistance of pathogens in urinary system infection.METHODS Collected from patients urine specimens of our hospital during Jan 2004 Dec 2008 were cultured,detected and studied drug resistance.RESULTS Among these pathogens,Escherichia coli rated the top one(44%),followed by coagulase negative Staphylococcus,fungi,Enterococcus,Klebsiella pneumoniae,Proteus and Pseudomonas aeruginosa.The Enterobacteriaceae were sensitive to imipenem(100%) and the Enterococcues and Staphytlococcus were sensitive to vancomycin(100%).But they all showed higher drug resistance to other antibiotics.CONCLUSIONS E.coli from urinary tract infection is the most common pathogen.In the treatment of urinary tract infection the commonly used drugs such as gentamicin,ciprofloxacin,etc,have produced a higher resistance.Clinician should pay attention to the changes in their drug resistance and use correctly.

Objective To explore the clinical effect of combination of vascularized fibular head epiphysis and peroneal neurovascular reverse flap repair defects of bone and skin in lateral malleolus in children.Methods Eight children with defects of bone and skin in lateral malleolus were recruited from May,2009 to September,2014.The age of children was ranging from 4 to 12 years old.Four children were injured by wheel twist,2 children were injured by traffic accident,1 was injured by machinery,and 1 was crashed with heavy object.The size of soft-tissue defect was ranging from 3 cm × 5 cm to 7 cm × 9 cm.The flap and bone healing along with ankle joint function scoring were evaluated.Patients were reviewed every 4 to 6 weeks during one year after their surgery,and they were reviewed every 6 months one year later.Results Secondary repair were conducted in all children.The curative effect got well after follow up for 6 months to 2 years(mean,12 months).The flap and fibular head epiphysis were well developed.The ossification of fibular head epiphysis did not found.According to American Orthopaedic Foot and Ankle Society (AOFAS) ankle function evaluation criteria,the results were excellent in 5 cases,good in 2 cases and poor in 1 at 10 months after operation.The shape and function of ankle joint were good,with one exception.The average motion degree of ankle joint was (68±5.12)°.Conclusion Combination of vascularized fibular head epiphysis and peroneal neurovascular reverse flap repair defects of bone and skin in lateral malleolus in children is effective.

ObjectiveTo explore the clinical effect of omeprazole combined with octreotide in treatment of patients with non-variceal upper gastrointestinal hemorrhage.Methods96 patients with non-variceal upper gastrointestinal hemorrhage were randomly divided into two groups.All the cases were received basic treatment of fluid infusion,transfusion and nutritional support.The control group( n =48) was treated with omeprazole alone,and the treatment group(n =48) was treated with omeprazole and octreotide.The course of treatment was 3 days.The vital signs,24h urine output,the number of cases of rebleeding in 72 h and adverse drug reactions was observed and recorded.ResultsThe total effective rate in treatment group and control group was 91.7％ and 72.9％,respectively.The difference between the two groups was statistically significant( x2 =5.79,P ＜0.05 ).The time of hemostasis and blood transfusion volume in treatment group were significantly less than those in control group(t =7.69,9.91,all P ＜0.05).The rebleeding rates after 72 hours of hemostasis between the two groups(8.3％ vs 25.0％ ) was significantly different ( x2 =4.80,P ＜ 0.05 ).In the course of treatment,the side effects weren' t found in both groups.ConclusionOmeprazole combined with octreotide was more effective and safe than omeprazole alone in fast stopping bleeding and reducing rebleeding rate.
