Objective To investigate the factor that related to neoplasm from the clinicopathologic character of gallbladder polyps, and identify the reciprocal effectiveness of these factors. Method Three hundred and forty-seven patients who were underwent operation with gallbladder polypoid lesions were reviewed. Results Logistic regression analysis showed, only 5 parameters were significant for the prediction of neoplastic lesions, including age of the patient (P =0.015), the number of polyps (P=0.018), the maximal diameter (P=0.000), echo property (P=0.000), as well as the position of polyps (P=0.030),of which the maximal diameter was the best one to predict the neoplasm polyps. Further analysis with HOC curve showed that 0.925 cm, the diameter of polyps, was the critical point to calculate the polyp was neoplasm or not. Conclusions Age of the patient , the number of polyps , the maximaldiameter, the position of polyps, and echo property are independent factors in predicting gallbladder neoplastic lesions. The size of the polyps is the most significant one among the factors to predict gallbladder neoplasm with its critical point of 0.925 cm.

Objective To evaluate the use of keyhole dynamic magnetic resonance (MR) imaging in evaluation of pituitary microadenomas. Methods Fifty three patients with pituitary microadenomas proved by operation or clinical findings such as headache, amenorrhea, lactating, fat or acromegaly were retrospectively studied on dynamic MR, conventional contrast enhanced MR, and unenhanced MR. Then the image data were analyzed by two experienced doctors who didn′t know the details and three degrees were made as follows: grade 0, no evidence of the tumor; gradeⅠ, asymmetry signals in the pituitary; and gradeⅡ, nodulated or sheets signals in the pituitary. The grading data were compared with statistical methods. Results In dynamic MR grading system: grade 0 was revealed in 1 patient, gradeⅠ in 29 patients and gradeⅡ in 23 patients. In conventional enhanced MR: grade 0 in 26 patients, grade Ⅰ in 17 patients and gradeⅡin 10 patients. In conventional unenhanced MR: grade 0 in 39 patients, grade Ⅰin 10 patients and grade Ⅱ in 4 patients. The diagnostic rate of dynamic MR, conventional enhanced MR, and unenhanced MR was 98.1%, 51.9%, and 26.4%, respectively. ( P

Objective Through the investigation of nurses'situation of fatigue and perceived social support, to know about the status of nurses' fatigue and the degree of perceived social support, and influenc-ing factors for a preliminary regression analysis of nurses in order to further the prevention of the occurrence of chronic fatigue for reference. Methods By using fatigue assessment scale (FAI), fatigue scale (FS-14)and perceived social support scale (PSSS) to investigate 200 female nurses in Jining city, 191 valid questionnaires were got, the reclaimed efficiency was 95.5%. The results underwent analysis. Results Nurses who had accounted for 69.11 percent of fatigue, had more severe fatigue than nurses who had less fatigue, and they had tense response to rest or sleep. Nurses' physical fatigue and mental fatigue were significantly higher than the general healthy population. Nurses received higher scores of social support. Age and other factors and perceived social support went through regression analysis: the degree of job tension exacerbated the severity of fatigue, however, social support to some extent, mitigated or alleviated the situation of nurses in the total fatigue. Conclusions Nurses are high-risk population for fatigue. The degree of job stress is the main influencing factor. And social support and care for nurses, especially home care support, adequate rest, in-creasing the number of nurses, good working environment can effectively reduce fatigue.

Objective: To explore the value of CYP2C19 genotype polymorphisms for guiding the strategy of anti-platelet therapy in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI) with clinical prognosis.
Methods: A total of 326 CAD patients with PCI treatment received CYP2C19 genotype examination. According to CYP2C19 polymorphisms, the patients were divided into 3 groups. The patients with CYP2C19*1/*1, fast metabolism were defined as Routine group, who received clopidogrel 75 mg/day,n=128. The patients with CYP2C19*1/*2, CYP2C19*1/*3, CYP2C19*2/*3, CYP2C19*2/*2, CYP2C19*3/*3, medium and slow metabolism were further divided into 2 groups as High clopidogrel group, who received clopidogrel 150 mg/day,n=99 and Ticagrelor group, who received ticagrelor 90 mg/bid,n=99. The changes of platelet aggregation rate (PAgT) at before and 1, 3, 6 months after PCI were observed, the major adverse cardiac events (MACE) and bleeding condition were compared among different groups at 6 months after PCI.
Results: The PAgT was similar between High clopidogrel group and Routine group at 1, 3, 6 months after PCI, P>0.05;while compared with High clopidogrel group and Routine group, the PAgT decreased in Ticagrelor group at 1, 3, 6 months after PCI,P<0.05. The occurrence of MACE was similar between High clopidogrel group and Routine group at 6 months after PCI,P>0.05; while compared with High clopidogrel group and Routine group, Ticagrelor group had much less MACE occurrence,P<0.05. Ticagrelor group had no more major bleeding events than the other 2 groups,P>0.05.
Conclusion: High dose clopidogrel does not increase MACE occurrence in CAD patients with CYP2C19 medium and slow metabolism after PCI. Ticagrelor may decrease PAgT and MACE occurrence without elevating the major bleeding events.

BACKGROUNDTo study to immunogenicity of recombinant HEV ORF2 protein expressed in pichia pastoris.

METHODSBALB/c mice were immunized with the recombinant HEV ORF2 protein. The ability of antiserum to bind HEV was tested using affinity-capture reverse transcription polymerase chain reaction (RT-PCR). Moreover, the recombinant protein was used to immunize BALB/c mice by different routes with different adjuvants. Serum conversion rate of anti-HEV antibody and the ELISA titer were detected.

RESULTSThe antiserum could capture native HEV for RT-PCR. As to the immunization effect, the immune response by intramuscular route was better than that of the intraperitoneal route. The protein with alum and CpG adjuvant could elicits more significant immune responses than using the alum adjuvant alone. The best way was to immunize with the protein with alum and CpG adjuvant by intramuscular route with a boosted injection on the 4th week after the first immunization. The ED50 was 0.023 microgram. This is the first report that the antibody elicited by recombinant HEV ORF2 protein expressed in pichia pastoris recognizes native HEV. High immunogenicity of this kind of ORF2 was also demonstrated by inducing strong immune response in mice with good ED50 result.

CONCLUSIONSThe high immunogenicity of this kind of HEV ORF2 may make a foundation for the development of new type of hepatitis E vaccine.

Objective Combination of nanoparticle with p53 and Rb gene therapy by gene targeting was applied to investigate its curative effect and safety evaluation on colorectal rabbit hepatic VX2 metastasis for tumor eradication and survival enhancement. Methods Recombinant expressing plasmids harboring wild type p53 and Rb were cotransferred or transferred separately to the rabbit hepatic VX2 metastasis by the emulsion of PLL-nHAP nanoplex and lipodiol through the hepatic artery in a tumor target manner. Subsequent co-expressions of p53 and Rb protein within the treated tumors were detected by Western blot and in situ analysis of confocal laser scanning microscope. The therapeutic effect was evaluated by the tumor growth velocity and the survival time of animals. Eventually, investigations of liver function were applied to evaluate the safety of the process. Results With safe procedure for the rabbits liver function, both p53 and Rb local nano-therapy showed favorable anti-tumor effects and increased animal survival time. p53+Rb local nano-therapy could significantly inhibit hepatic VX2 metastasis and enhance the animal survival time compared with p53 local nano-therapy or Rb local nano-therapy. Local nano-therapy showed no significant influence to animal liver function. Conclusions Rb can work synergistically with p53 in the combined therapy mediated by PLL-nHAP nanoplex to augment the anti-tumor effect. The local nano-therapy with p53 and Rb is likely to be an effective and safe anti-tumor therapy for hepatic colorectal metastasis.

Objective: To explore the relationship between pre-operative severe cyanosis (SC) and the early post-operative recovery in pediatric patients with corrective operation of Tetralogy of Fallot (TOF) Methods: A retrospective cohort study was conducted in 271 pediatric TOF patients who received corrective operation in our hospital from 2010-03-01 to 2013-03-01. Based on pre-operative hemoglobin≥180g/L, the patients were divided into 2 groups: SC group,n=48 and Non-SC group,n=223. Univariate analysis was performed to compare the differences between 2 groups; binary Logistic regression analysis was carried out to identify significant changes which was defined byP<0.01 in univariate analysis. Results: Univariate analysis indicated that compared with Non-SC group, the patients in SC group had the higher incidence of post-operative complications,P<0.001, longer time to reach negative fluid balance,P=0.006 and prolonged mechanical ventilation time,P=0.001; while the post-operative kidney injury was similar between 2 groups,P=0.036. Binary Logistic analysis presented that the patients in SC group needed prolonged mechanical ventilation time (OR=3.432, 95% CI 1.014-5.978,P=0.015), longer time to reach negative fluid balance (OR=4.823, 95% CI 2.586-8.941,P=0.002), the higher incidence of post-operative complications (OR=14.322, 95% CI 7.114-26.251,P<0.001). Conclusion: Pediatric TOF patients with pre-operative SC had the higher incidence of early post-operative complications, prolonged mechanical ventilation time and longer time to reach negative fluid balance those resulting delayed post-operative recovery.
