Objective To investigate the expressions of Yes-associated protein-1 (YAP1) in gallbladder mucosal epithelium of normal persons,in patients with simple/calculous cholecystitis,and in patients with gallbladder carcinoma;and to study the mechanism of YAP1 in gallbladder carcinoma development.Methods Immunohistochemistry was used to detect the expression and distribution of YAP1 protein in 50 persons with normal gallbladder,101 patients with simple cholecystitis/calculous cholecystitis and 100 patients with gallbladder carcinoma.RT-PCR and western-blot were used to detect the mRNA and protein levels of YAP1 in normal and malignant gallbladder mucosal epithelium cells.siRNA was used to shut down the expression of YAP1 in SGC996 cells.MTT was used to test cell vitality.Flow cytometry was used to measure cell cycle.Results Immunohistochemistry revealed the expression rates of YAP1 in the gallbladder carcinoma group,the cholecystitis/gallstone group and the control group to be 87.0％ (87/100),56.4％ (57/101) and 5.0％ (1/20),respectively (P ＜ 0.01).The YAP1 protein levels were higher in gallbladder carcinoma tissues and cells when compared to normal tissues and cells.RT-PCR showed the mRNA levels of gallbladder carcinoma cells to be 12.5 ± 1.2 times of normal gallbladder mucosal epithelial cells (P ＜ 0.05).After using siRNA to shut down the YAP1 expression,EMT associated proteins were down-regulated,cell vitality was decreased,and cell cycle was arrested in the S-phase.Conclusions YAP1 is closely related to cell proliferation and metastasis of gallbladder carcinoma.It may promote tumor progression through epithelial-mesenchymal transition.transition;Tumor progress

Objective To establish a tree shrew mode of breast tumor.Method Forty-five 3 to 4 month-old female tree shrews were orally gavaged with 20 mg 7,12-dimethylbenz(a)anthracene (DMBA) or peanut oil per animal for three times.Following that, fifteen DMBA administrated tree shrews were implanted 90 day-release medroxyprogesterone acetate ( MPA) pellets.The tree shrews were palpated once weekly to detect mammary tumors for 45 weeks after first DMBA administration.Results DMBA were able to induce breast tumors (12.5%) in tree shrews, and MPA increased the tumor incidence (50%) while no breast tumors were observed in the control group.Three induced breast tumors were intraductal papillary carcinomas and one was IDC by H&E stain.Conclusion All induced tumors are similar with spontaneous tumors in structure and molecular markers.

0.1) were not significantly different.Conclusion The seropositivity of H.pylori,anti-CagA and anti-H.pylori-IgG are associated with the risk of gastric cancer.

AIM: To evaluate the accuracy of central conreal thickness ( CCT ) using EX500 Excimer Laser workstation (EX500) in laser in situ keratomileusis (LASIK) patients.METHODS:The CCT of 120 eyes (63 patients) who had LASIK between January 2013 and June 2013 were measured by A- scan and EX500. Three groups were classified: >550μm, 500 ~550μm, <500μm according the CCT value of A-scan. The CCT were measured again by corneal flap creating by moria SBK microkeratome. The thickness of the corneal bed stroma were measured by A-scan and EX500 after keratomileusis. All outcomes were analyzed with paired t test.
RESULTS: The average preoperative CCT value was 527. 9±34. 3μm measured by A-scan, 528. 5±34. 6μm measured by EX500. There was no significant difference between these two measurements (t=1. 736, P=0. 085). In group which CCT >550μm, the average preoperative CCT value was 571. 4±17. 3μm measured by A-scan, 572.7±15. 7μm measured by EX500. There was no significant difference between these two measurements (t=1. 857, P=0. 072). In group which CCT 500 ~ 550μm, the average preoperative CCT value was 523. 4±13. 1μm measured by A-scan, 524. 2±12. 4μm measured by EX500. There was no significant difference between these two measurements ( t=1. 934, P = 0. 058 ). In group which CCT <500μm, the average preoperative CCT value 484. 5±9.8μm measured by A-scan, 483. 7±8. 9μm measured by EX500. There was no significant difference between these two measurements (t=1. 395, P=0. 174). The average CCT value after corneal flap lifting was 401. 3 ± 34. 2μm measured by A-scan, 393. 4±38. 9μm measured by EX500. There was a significant difference between these two measurements ( t = 6. 669, P = 0. 000 ). The average thickness of the corneal bed stroma value after keratomileusis was 332. 6±38. 3μm measured by A-scan, 307. 3 ± 37. 1μm measured by EX500. There was a significant difference between these two measurements ( t=17. 165, P=0. 000).
CONCLUSION: There is no significant difference between preoperative CCT value measured by A-scan and EX500. After corneal flap lifting and keratomileusis, the CCT value measured by EX500 is smaller than measured by A-scan.

Objective:To research whether ectopic over-expression of Pim-2 could cause chang-liver cell (LO2) malignant transformation,to explore the relationship between Pim-2 protein and hepatocellular carcinoma.Methods:Three groups of cells were arranged including human chang liver cell line LO2 (group C),LO2 cells transfected with empty-vector (group B) and LO2 cells transfected with Pim-2 gene (group A).Pim-2 expression levels were detected.The morphology,proliferation level,apoptosis rate and migration ability of the cells were detected respectively.The cells were subcutaneously inoculated into athymic mice and the microstructures of the neoplasm were observed by optical and electron microscopy.Results:Compared with group B,Pim-2 expression levels were significantly higher in group A (P＜0.05),and their morphology had obvious malignant changes.They also showed a significantly increased proliferation rate (P＜0.05) and migration capacity (P＜0.05),as well as a significantly decreased apoptosis rate (P＜0.05).Only the athymic mice inoculated with group A could generate neoplasm,and the morphology of the neoplasm coincided with that of the hepatoma.Conclusion:Both the morphological and biological changes of LO2/Pim-2 cells indicate the trend of malignant transformation,which could generate hepatoma in athymic mice.Pim-2 could induce malignant transformation of human liver.

Methods AD tree shrew model was established by intracerebroventricular injection with amyloid-βpeptide (Aβ) . Since the eighth day after injection, the tree shrews were treated with gastrodin for thirty days. The expression of BDNF in tree threw hippocampus was detected by reverse transcription polymerase chain reaction (RT-PCR) . Results The expression of BDNF mRNA in the treatment group was higher than that in the model group ( <0.05) . Conclusion Gastrodin can increase some degree of the expression of BDNF.

Objective To explore the effect of clinical nursing path (CNP) on stroke patients. Methods 80 stroke patients were divided into control group and experimental group with 40 cases in each group. The control group received functional nursing, while the experimental group received care in accordance with the design of CNP map. Results The mastery rate of health knowledge and the satisfaction rate were higher, and the hospitalization time was shorter in the experimental group than in the control group (P<0.05). Conclusion The implementation of CNP could increase the mastery degree of health knowledge, improve the satisfaction rate of patients for nursing service, and shorten the hospitalization time.

OBJECTIVETo explore the impacts on the fine movement of upper extremity with flaccid paralysis in stroke treated with acupuncture and motor imagery.

METHODSSixty-two cases of flaccid paralysis of upper extremity in stroke were randomized into an observation group (30 cases) and a control group (32 cases). In the control group, the conventional western medication and the passive movement of the extremity were applied. Additionally, the penetrating needling technique was used at the head points [penetrating needling from Baihui (GV 20) to Taiyang (EX-HN 5)] and the local affected extremity [penetrating needling from Jianyu (LI 15) to Binao (LI1 14), from Quchi (LI 11) to Shaohai (HT 3), from Waiguan (TE 5) to Neiguan (PC 6), etc]. The needles were retained for 30 min. In the observation group, on the basic treatment as the control group, during the needle retaining, the motor imagery therapy was supplemented. The treatment was given once a day, 5 treatments a week, for 4 weeks totally in the either group. The scores in the action research arm test (ARAT) and the modified Fugl-Meyer assessment (FMA) were recorded at the moment of enrollment, in 2 and 4 weeks of treatment, in the 6th and 8th weeks, as well as after 90 days separately.

RESULTS(1) ARAT score: since the 2nd week, ARAT scores in the observation group were all improved significantly as compared with those in the control group at the each time points (all P<0. 05). In the observation group, the scores were improved significantly in the pair comparison at the time points (all P<0. 05). In the control group, the score in the 2nd week was not different significantly as compared with that before treatment (P>0. 05), but the scores at the rest time points were improved significantly in the pair comparison (all P<0. 05); (2) FMA score: in the 2nd week and on the 90th day, FMA score in the observation group was higher significantly than those in the control group (both P < 0. 05). In the observation group, the scores were all improved significantly in the pair comparison at the time points (all P<0. 05). In the control group, except that in comparison between the 90th day and the 8th week (P>0. 05), the results were all P<0. 05 at the rest time points.

CONCLUSIONThe early intervention of the combined therapy of acupuncture and motor imagery effectively promotes the recovery of the coordination function and the fine movement of upper extremity, especially the improvements of the fine movement in stroke at flaccid paralysis stage. The efficacy is better than the single acupuncture treatment.
