Compared with open surgery, laparoscopic surgery (LS) provides distinct advantages. However, LS is limited because of the lack of flexibility and tactile feedback. These drawbacks may result in prolonged learning curve and increase in difficulty of sur-gery, particularly for reconstructive LS. This study aimed to determine more efficient methods and resolve several limitations, such as surgical education, LS, surgical procedures (suturing and knotting), iconography, and biotechnology in LS. This review provides a broad overview of studies related to this field.

0.05).But there were significant difference in operation time,blood loss,time of resumption of food,time of intestinal function recovery,length of hospital stay and complications between OC group and LC group(P

Background and purpose: miR-210 was closely related to the occurrence and development of gastric cancer, but its mechanism and clinical significance were still not clear. The purpose of this study was to explore the expression of miR-210 in gastric cancer tissues and its clinical significance. Methods: The expression of miR-210 was detected in gastric cancer tissues and the corresponding adjacent tissues. The relationship between the expression of miR-210 and clinical pathological factors and prognosis was analyzed. Results: Real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) showed that the expression of miR-210 in gastric cancer was higher than that in adjacent tissues, and there was a significant difference between the two groups (P<0.05). The expression of miR-210 was closely related to tumor size, lymph node metastasis and TNM stage, but was not related to age, gender, tumor dif-ferentiation and depth of invasion. The 5-year survival rate of patients with low miR-210 expression was 48.2%, where-as the 5-year survival rate of patients with high miR-210 expression was 30.4% (χ2=4.216, P=0.040). Conclusion: The expression of miR-210 in gastric cancer was higher than that in adjacent tissues, and maybe related to the development and prognosis of gastric cancer. miR-210 is expected to be a new diagnostic marker and therapeutic target for gastric cancer.

Objective To explore the relationship of attentional function,coping style and depressive symptoms in depression disorders.Methods Sixty-eight depression disorder and seventy-one normal healthy people were assessed by Hamilton depression scale(HAMD),coping style questionnaire and digit span forward.Independent samples t test and hierarchical multiple linear regression analysis were used to analyze all data.Resuits Compared with the control group,depressed patients had higher blaming(0.57 ± 0.29 vs 0.29 ± 0.25,P ＜0.01),wishful thinking(0.55 ± 0.22 vs 0.42 ± 0.26,P ＜ 0.01) and avoidant (0.63 ± 0.18 vs 0.46 ± 0.21,P ＜0.0l),lower problem solving (0.67 ± 0.23 vs 0.80 ± 0.18,P ＜ 0.01),rationalization (0.51 ± 0.20 vs 0.59 ±0.06,P＜0.01) and poorer attentional function(6.90 ± 1.65 vs 7.54 ±0.98,P＜0.01) ;but there was no significant differences in support seeking score.Hierarchical multiple linear regression analysis revealed that,even when controlling for age,sex,low score of support seeking were independently predicted attentional function impairment (β =-0.25,P＜0.05).In addition,the use of support seeking was found to mediate the relationship between digit span forward and retardation completely.Conclusion Retardation indirectly influence the attention function by the mediating of support seeking.

Objective:To assess the role of EGFR mutations on pemetrexed response in patients with advanced lung adenocarcino-ma. Method: Forty pulmonary adenocarcinoma patients with evaluable lesions were retrospectively screened .They had been treated with pemetrexed-included chemotherapy and had EGFR gene test results. The evaluation endpoints were overall response rate,disease control rate and progression free survival. Result:No significant statistical difference was seen in overall response rate(ORR) (44.4%VS 31.8%, respectively) and disease control rate(DCR) (88.9%VS 81.8%, respectively ) between EGFR wild group and EGFR muta-tion group, but patients in EGFR wild group had longer progression free survival(PFS) ( 8.9 months VS 5.3 months;P=0.046). Conclu-sion:EGFR mutation status can influence the efficacy of pemetrexed.

Objective To investigate the characteristics of cognitive dysfunction in patients with depression,and identify the correlation between cognitive dysfunction and serum brain-derived neurotrophic factor (BDNF) level.Methods All participants including 73 depressed patients and 71 healthy controls were received clinical and cognitive assessments at admission,the depression group was divided into two groups by the score of Beijing version of the Montreal Cognitive Assessment (MoCA-BJ),one was depression with cognitive dysfunction group which had 36 cases,the other was depression without cognitive dysfunction group which had 37 cases.Concentration of BDNF was measured by the ELISA method.Results Cognitive impairments were found in numerous cognitive domains of depressed patients,including visuospatial and executive abilities,attention,delayed recall and orientation(P ＜ 0.05).The incidence of cognitive dysfunction in depression was 49.3％.There was not significant difference between two depressive groups (depression with cognitive disorder(12.08 ± 7.08)ng/ml,depression without cognitive disorder (12.22 ± 7.93)ng/ml,P ＞ 0.05),and the levels were significantly lower than that in healthy people ((16.55 ± 7.47) ng/ml,P＜ 0.01),and serum BDNF level had no positively relevant with different cognitive functions (P ＞ 0.05).Conclusion Depression patients have cognitive dysfunction in numerous cognitive domains,including visuospatial and executive abilities,attention,delayed recall and orientation.Serum BDNF level is closely related with depression,while,it has no obvious relationship with cognition function in depression.

Objective To explore the relationship between polymorphisms of brain-derived neurotrophic factor(BDNF) gene (rs6265 and rs12273539) and cognitive impairment in depressive disorder.Methods All participants including 73 depressed patients and 71 healthy controls were received clinical and cognitive assessments at admission,and then the depression group was divided into two groups by the score of Beijing version of the Montreal Cognitive Assessment (MoCA-BJ).One was depression with cognitive dysfunction group,and the other was depression without cognitive dysfunction group,with 36 and 37 cases respectively.The polymorphisms of BDNF gene was identified by PCR-RFLP.Results No significant difference for rs6265 gene types(x2=5.18,P=0.27),A allele carries (x2 =4.28,P=0.12) and G allele carries (x2 =1.95,P=0.38) among the three groups.There was no significant difference for rs12273539 gene types,allele carries between patients without cognitive dysfunction and controls groups(P＞0.05).There was much more C-allele carries (x2=5.40,P=0.02)and less T-allele(x2=6.06,P=0.01) in patients with cognitive disorder than those in health and it was different in rs12273539 gene types between the two groups(x2=8.38,P=0.02).CC/CT/CT gene type performed different on attention function (P＜0.01).Conclusion BDNF rsl2273539(T/C) gene type has relationship with the onset of cognitive disorder in depressed patients,and there are more C-allele carries in depressive patients.The depression patients with CC gene type are worse on the attention function impairement.

AIM:To observe the effects of neuroglobin ( NGB) overexpression on the apoptosis induced by Aβin the brains of double transgenic AD ( APPswe/PS1dE9) mice and to explore its potential mechanisms .METHODS:Twenty-four 13-month-old double transgenic AD mice were randomly divided into 3 groups:intracerebroventricular injection with normal saline (NS) group, intracerebroventricular injection with pcDNA3.1 and NS group, and intracerebroventricular injection with pcDNA3.1 and pNGB group.Immunohistochemistry was used to detect the expression of Aβ1-42 in the brains. TUNEL staining was used for analyzing the apoptosis , and the protein levels of cleaved caspase-3, caspase-9, PI3K, Akt and p-Akt were determined by Western blot .RESULTS: After intracerebroventricular injection with pNGB , the areas of Aβ1-42 in the hippocampus and cortex were decreased compared with NS group and pcDNA 3.1+NS group (P<0.01).The TUNEL-positive staining cells in the pNGB group were less than those in NS group and pcDNA 3.1 group ( P<0.01 ) . NGB overexpression attenuated the protein levels of cleaved caspase-3 and caspase-9 (P<0.01), but induced the produc-tion of PI3K and p-Akt (P<0.01).CONCLUSION:Overexpression of pNGB significantly inhibits the generation of Aβand attenuates the apoptosis induced by Aβ, indicating that NGB overexpression activates PI 3K/Akt pathway and inhibits the production of cleaved caspase-3 and caspase-9, which were tightly related with apoptosis .
