Objective To investigate the role of PAK1 in the development of pancreatic cancer.Methods 33 cases of pancreatic cancer in Renmin Hospital of XianTao were selected in this study. 33cases of pericancerous normal tissues were collected as control group.Immunohistochemical staining were performed to detect the expression of PAK1 in 33 cases of pancreatic cancer and pericancerous normal specimens.Results By Immunohistochemical staining PAK1 were mainly expressed in the cytoplasm. The positive rate of PAK1 expression in pancreatic cancer were 69.7 ％(23 / 33),which was significantly higher than that of control group[27.3 ％(9 / 33),x2=11.89,P =0.001].In addition,overexpression of PAK1 was more frequently in Ⅲ+Ⅳ stage pancreatic cancer tissue[93.3 ％(14/15)],compared with Ⅰ + Ⅱ stage [50.0 ％( 9 / 18 ),x2=5.367,P=0.021]. Conclusion The PAK1 protein may be associated with the occurrence and development of pancreatic cancer.

Science of Meridians and Acupoints of the new version has been obviously improved in terms of bookbinding and printing quality and the concrete textbook content as compared with the textbook of the old version. However, some questions had been discovered during actual usage in the past semester. The writer makes the discussion from 4 aspects, named content arrangement, content statement, content correction and phonetic notation of rare words. The writer puts forward his own opinions on a part of acupoints essentially and points out some mistakes in the textbook.

Objective To analyze the clinical features and risk factors of migraine patients with white matter le-sions (WMLs). Methods One hundred ten clinically diagnosed migraine patients who underwent magnetic resonance im-aging (MRI) scans from October, 2010 to August, 2013 were enrolled in Shandong Provincial Hospital. One hundred ten migraine patients were divided into two groups:WMLs group and non-WMLs group based on the presence or absence of WMLs in MRI scans. The clinical features of the patients and location and number of WMLs were investigated. Noncondi-tional multivariate stepwise logistic regression after univariate analysis was used to analyze the data. Odds ratio (0R) and 95 confidence interval after adjustment for possible confounding variables were calculated. Results①There were 36 patients with WMLs among the 110 migraine patients. The incidence of WMLs in migraine patients was 32.7%. The WMLs in migraine patients were predominantly present in the frontal and parietal lobes (59.1%). ② Compared with non-WMLs group, there were significant increases in disease duration (5.3±3.7 vs. 7.6±4.9, P﹤0.01), frequency of head-ache attack (3.5 ± 2.3 vs. 4.6 ± 2.2, P﹤0.05), aura (18.9%vs. 36.1%, P﹤0.05) and family history of migraine (12.2%vs. 44.4%, P﹤0.01) in WMLs group.③The independent risk factors of WMLs in migraine patients were family history of mi-graine (OR=5.995), aura (OR=3.067) and long disease duration (OR=1.165). Conclusions Family history of migraine, au-ra and disease duration are the predictive risk factors of WMLs in migraineurs.

Objective To study the experience of laparoscopic repair in gastric and duodenum perforation. Methods 35 patients with gastric and duodenum perforation were performed laparoscopic repair.Results 34 pati- ets with gastric and duodenum perforation were safely operated.1 case with perforation of gastric carcinoma was con- verted to open for radial gastrectomy.The mean time of hospitalization was 7.5 days.There was no intraoperative and postoperative complications.Pathological examination showed 4 patients with perforation of gastric ulcer and one with perforation of gastric carcinoma.Conclusion Laparoseopic repair was one of the safe,quick recovery and little suffering treatment for duodenum perforation.

Objective To investigate the effects of children's mentality on mental symptoms during recovery period of ketamine anesthesia. Methods According to the mentality, forty-five children undergoing smalminor surgery were assigned into active group, stable group and fretful group with 15 cases each. Child was anaesthetized by ketamine alone. RP, BP, HR and SpO_2 were recorded at the end of operation, 5,10 and 30 min after operation. Meanwhile the expression, feeling, behavior, talking and activity were observed. Results RR, BP, HR in active group and fretful group were significantly higher than those in stable group. There was a significant difference in the expression, feeling, behavior, talking and activity among three groups. Conclusion Children's mentality has a significant effect on mental symptoms and hemodynamics during recovery period of ketamine anesthesia.

Objective To study the effect of Bifidobacterium spent culture supernatant (SCS) on adhesion of Pseudomonas aeruginosa to intestinal epithelial cells. Methods The intestinal epithelial cells were cultured,then divided into three groups: control,Pseudomonas aeruginosa adhesion group,SCS and Pseudomonas aeruginosa adhesion group. The effects of SCS on cell viability,the number of adhering and invasive bacteria were evaluated with MTT assay and lysis-counting assay in 1,3,6 h. Results At 3 h after SCS treatment,the amount of Pseudomonas aeruginosa decreased significantly,and the number of adhering and invasive bacteria decreased by 71% and 87% respectively. Conclusion SCS could protect the intestinal epithelial cells by inhibiting the adhesion and invasion of Pseudomonas aeruginosa.

Objective To assess the evolution of gastric epithelial dysplasia (GED). Methods We reviewed the history of 239 of patients with gastric dysplasia diagnosed by endoscopic biopsy, and 195 were followed up for 61. 37 months. Results Among 239 cases of dysplasia (261 lesions) , there were 119, with mild dysplasia, 77 with moderate dysplasia, and 43 with severe dysplasia. The gastric dysplasia lesions are mainly in lesser curvature, and its endoscopic appearance mostly is localized erosion. In the follow - up group, regression of dysplasia was demonstrated in 86. 36% , 81. 25% , and 47. 62% of mild, moderate and severe dysplasia respectively. Progression to gastric cancer was detected in 8. 18% , 15. 63% , and 72. 09% of mild, moderate, and severe dysplasia, respectively. The relative risk (RR) of mild, moderate, severe dysplasia was 1. 96, 3. 74, and 17. 25 respectively. Conclusion Carcinomatous evolution of GED increases proportionally with its histological grade. Gastroscopy biopsy follow-up should be held up for all grades of GED, especially, in high grade GED, gastroscopy and biopsy should be taken as soon as possible.

Objective To observe the features of cognitive function impairment in different locus of cerebral stroke and study the correlation between locus of cerebral stroke and cognitive function impairment.Methods Cognitive function was evaluated by Montreal cognitive assessment(MOCA) in 100 patients with stroke(63 cases of cerebral infarction,37 cases of cerebral hemorrhage).The locus of cerebral stroke in the 100 patients were including frontal lobe 15 cases,parietal lobe 15 cases,temporal lobe 12 cases,occipital lobe 8 cases,thalamus 14 cases,basal ganglia 20,cerebellum 8 cases and pons 8 cases.Correlation between the locus of cerebral stroke located by CT/MRI,and cognitive impairment was analyzed with 7 items(ORI,EF,NAM,MEM,ATT,LANG,ABS) of MOCA.Results(1) Stroke locus in frontal lobe,temporal lobe,parietal lobe,occipital lobe,thalamus and basal ganglia had correlation with obvious cognitive function impairment(all P

?AIM:To investigate the causes and characteristics of retinal detachment after vitrectomy.?METHODS: Retrospective analysis of patients in our hospital in recent 4a who underwent primary, standard, three -port pars plana vitrectomy ( PPV ) . Retinal detachment occurred in 24 eyes ( 23 cases ) , 24-67 years old, average 49.0±12.0 years old.There were male in 17 cases, female in 6 cases, 6 right eyes, 18 left eyes.?RESULTS:Eighteen (75%) eyes without any symptoms were found during a routine check, 6 eyes ( 25%) with decreased visual acuity or in front of shadow.It took 1-223d from PPV to retinal detachment, average 40.7 ± 54.2d, of which retinal detachment occurred in 10 (42%) eyes within 1wk, 14 (58%) eyes within 1mo.The direct cause of retinal detachment was new retinal break ( a total of 27 holes ) in 19 eyes, proliferative vitreoretinopathy ( PVR) in 4 eyes, 1 eyes with primary hole not closed.All retinal detachment were ultimately completely reset.?CONCLUSION: The occurrence of new retinal breaks is the main cause of retinal detachment after vitrectomy, attention should be paid to the early postoperative peripheral retinal examination;after a timely surgery, the retina can be reset.
