Pancreatic cancer is a common disease with a poor prognosis. Despite recent advance in the field of diagnos-tic technique, surgical resection and adjuvant therapy for pan-creatic cancer, the overall 5-year survival rate is still less than 5%. This is due to its aggressive growth behavior, early local invasion and metastasis, and resistance to chemotherapy and radiation therapy. Surgical treatment is still regard as the only chance for curing pancreatic cancer. Many new strategies in the surgical treatment of pancreatic cancer, including extended lymphadeneetomy, vascular resection, the use of laparoscopy, surgery for metastastic or recurrent disease, and neoadjuvant therapy, are currently under debate. In this review, we discuss the current status of surgical treatment for pancreatic cancer, and highlight the controversies and focus.

Objective To investigate the effects of lipopolysaccharide(LPS) on the expression of hypoxia inducible factor-1?(HIF-1?) and its target gene glucose transpoter-1(GLUT-1)in human monocyte lines THP-1. Methods THP-1 cells were stimulated with 1 ?g/mL LPS for 0,2,4,6 or 8 h.The expression of HIF-1? protein of THP-1 cells was detected by Western blotting,and RT-PCR was employed to detect the expression of HIF-1? mRNA and GLUT-1 mRNA.THP-1 cells were exposed to different concentrations of LPS(0,0.01,0.1 and 1 ?g/mL) for 6 h,and the expression of HIF-1? protein of THP-1 cells was detected by Western blotting. Results The expression of HIF-1? protein of THP-1 cells began to increase 2 h after being treated with 1?g/mL LPS,significantly increased after exposure for 4 h(P

Objective To screen melanocortin 4 receptor (Mc4R) gene mutation by direct DNA sequencing in order to explore the mutation situation of Mc4R gene in simple obese children in Nanjing.Methods One hundred and five simple obese children(obesity group) and 127 healthy children(healthy control group) were examined for mutations of Mc4R gene.Body mass index(BMI)cutoff points for overweight and obesity adopted Chinese children and adolescents,recommended by China Working Group of Obesity,and all children had no other hereditary and metabolic abnormality.Touch-down PCR was performed to amplify the full length Mc4R gene,then direct DNA sequencing was used to analyze the Mc4R gene.The differences of biochemical index levels between obesity group and healthy control group were analyzed ,including alanine transaminase,aspartate transaminas,total protein,albumin,globulin,albumin/globulin,triglyceride,cholesterol,high density lipoprotein,cortisol,insulin and C peptide.Results There were significant differences of biochemical index levels between obesity group and healthy control group,including triglyceride,insulin level after dining 2 h,C peptide and BMI(Pa

Objective To summarize the clinical and pathological features of exaggerated placental site (EPS),explore its pathogenesis regularity,diagnosis and treatment strategies.Methods The clinical data related to 34 patients with EPS were analyzed retrospectively.Results In 34 patients,11 patients performed full-term cesarean section,2 patients performed normal vaginal delivery,the other 21 patients had abortion.Thirty-one patients had pregnancy history.Fifteen patients performed hysterectomy,13 patients performed dilatation and curettage,6 patients performed exploratory hysteroscopy and lesions resection.All the patients survived after treatment.Conclusions The patients can not be diagnosed in the antepartum and intrapartum,but can be diagnosed relying on the pathological diagnosis.When it is ineffective to stop bleeding after delivery or abortion by conventional treatment,we should consider the possibility of EPS.Timely perform hysterectomy is theeffective method to stop bleeding,can save the life of patients.If bleeding is not much,curettage or exploratory hysteroscopy can get a significant effective treatment and avoid hysterectomy.

Objective To discuss the value of medium resolution typing method for HLA-B antigens of Northern Chinese by DNA chip technique.Methods The chip was made with specific medium distinguish typing probes designed according to gene frequency of HLA-B alleles from Northern Chinese.Unsymmetrical PCR was used to amplify HLA-B exon 2 and 3, then labeled PCR products and hybridize with probes on the chip.Certified the typing of HLA-B by analysed and scanned the signals of hybridize through a set of computer software.Results HLA-B alleles were successfully typed in 30 clinical samples. This medium distinguish probes were able to discern 42 HLA-B alleles from the scope of HLA-B 7~83. Using it we can distinguish B14,73 and 82 three new alleles contrast to PCR-SSP methods.Conclusions DNA typing of HLA-B by chip was proven to be a high-resolution and high-specificity method. It is able to check out the multitudinous samples in one DNA chip and it is more suitable for clinical application.

Objective To make a systematic evaluation of the efficacy and safety of Eszopiclon and Alprazolam in the treatment of insomnia.Methods By searching the PubMed,Cochrance Library,CNKI, WANFANG,and VIP database,we studied the literature published between 2005 to 2016 on the efficacy and safety of Eszopiclon and Alprazolam in the treatment of insomnia.We collected the randomized controlled trials (RCTs), evaluated the quality of methods and then analyzed the data using RevMan5.3 software.Results A total of 18 RCTs were included,involving 2088 patients.According to Meta-analysis,Eszopiclon group had a significantly higher total efficacy rate [RR=1.07,95% CI (1.02,1.11),P=0.003],lower severity of adverse reactions [MD=-0.43,95% CI(-0.75,-0.12),P=0.008]and incidence of adverse reactions [RR=0.46,95% CI(0.32, 0.66),P<0.0001]than Alprazolam group.However,the two groups did not significantly differ in sleep quality scores after 4-week teatment [MD=-0.05,95% CI(-0.22,0.12),P=0.54].Conclusion Eszopiclon is more effective on insomnia than Alprazolam,with better safety,and it deserves wide clinical use.
