Objective To discuss the effect of theme preview-case study on clinical training for nursing students in Cardiology Department. Methods A total of 56 clinical nursing interns of cardiology in January 2013 to December 2013 were selected as observation group, 54 clinical nursing interns of cardiology in January 2012 to December 2012 were selected as control group. The students of the control group underwent traditional infusion teaching method, while students of the observation group received theme preview-case study based on traditional method. We compared the comprehensive ability of nursing students, the satisfaction of clinical teachers to nursing students and the satisfaction of nursing students to clinical teachers after training. Results After training, (93. 4 ± 3. 5) scores had been acquired in the observation group, which was higher than (84. 8 ± 4. 6) in the control group (t= -3. 898,P<0. 05). The assessment of student′s ethics and labor discipline by clinical teachers were no statistically significant between two groups (P>0. 05), but had statistical significance at work attitude, learning enterprise, errors, work capacity and total assessment (P<0. 05); the nursing teaching method, occupational teaching contents, teaching attitudes and total scores had statistical significance (P < 0.05). Conclusions The theme preview-case study teaching method can improve the comprehensive ability and learning interesting of nursing students in Cardiology Department, and improve the interns′job satisfaction and the interns′satisfaction for teacher′s job.

Objective· To explore the frequency, nondetection rate, and clinical importance of incidental extracerebral findings (IECFs)on brain nonenhanced magnetic resonance imaging(MRI). Methods · The MRI data of 7 930 cases with suspected intracerebral lesionin were retrospectively analyzed. IECFs were categorized as E1 (clinically unimportant, e.g., sinus mucosal thickening), E2 (likely unimportant, e.g.,pharyngeal mucosal symmetrical thickening), and E3 (potentially important, e.g., pharyngeal mucosal asymmetrical thickening). The nondetection rate was determined by comparing the results of the structured approach with the initial MRI reports. The medical records were examined for patients with E3 IECFs to assess clinical importance and outcome of these lesions. Results · A total of 5 992 IECFs were found in 4 213 patients (53.13%, 4 213/7 930). IECFs with E1 was 82.2% (4 924/5 992), E2 was 16.6% (995/5 992) and E3 1.2% (73/5 992). Overall IECFs and E1 findings were occurred more commonly in male patients (P=0.000, P=0.024). And the statistically significant difference was also found among different age groups (P=0.000). The nondetection rate was 56.9% (3 409/5 992) for overall IECFs and 32.9% (24/73) for E3 IECFs. Of the 73 patients with E3 IECFs, 34 (46.6%) received final diagnosis and appropriate treatment during the study period. Conclusion · IECFs are prevalent in clinical patients on brain MRI with a nondetection rate of 32.9% for potentially important (E3) findings. The reporting of IECFs according to clinical importance is helpful for patients' management.

OBJECTIVETo investigate the impact of energy metabolism at the cellular level on the expression of the water channel protein aquaporin 1 (AQP1).

METHODSBalb/c mouse fibroblasts were incubated with iodoacetamide (IA) in vitro, and the changes in AQP1 expression were detected by immunoblotting and immunohistochemistry at 0, 4, and 6 h.

RESULTSIA induced the expression of AQP1 at 4 and 6 h accompanied with cell death. Reverse transcription PCR showed an increased expression of AQP1 mRNA in the cells. AQP1 expression was also upregulated by the inhibitor of microtubule and cytochrome C oxidase.

CONCLUSIONA pretranslational regulation occurs in IA-induced AQP1 expression in mouse fibroblasts, and the up-regulated AQP1 accumulation is characterized by mitochondria-related energy dependence.

Objective To summarize the clinical features of non-classic infantile glycogen storage disease type Ⅱ for early diagnosis.Methods The clinical data including the clinical manifestations and investigation of the 3 nonclassic infantile glycogen storage disease type Ⅱ were retrospectively reviewed from Jun.to Jul.2011.All the 3 cases were diagnosed by measuring acid α-glucosidase (GAA) activity in blood sample.Results All the 3 patients presented development delay,limb muscle weakness without hepatomegaly.Two cases of them presented weakness of respiratory muscle.The serum creatine kinase,aspartate aminotransferase and alanine aminotransferase were high in all the 3 patients.Electromyography studies indicated that one of the patients with susceptible myopathy,one patient with neurogenic damage and one patient with mixed damage of the neuromascular.Echographic evidence of hypertrophic cardiomyopathy was detected in 2 patients.GAA activity of the 3 patients in blood sample had diagnostic value.Conclusions Nonclassic infantile glycogen storage disease type Ⅱ is easy to be missed due to its non-significant clinical manifestations.The results suggested that GAA activity in blood sample should be screened for the patients with motor development delay,decreased muscle weakness/exercise tolerance and increased of serum creatine kinase.

OBJECTIVETo establish and characterize imatinib-resistant gastrointestinal stromal tumor (GIST) xenografts. Further provided an ideal experimental platform through the imatinib-resistant GIST xenografts to investigate the mechanism of resistance to imatinib.

METHODSImatinib-resistant GIST cells were injected under the skin of athymic nude mice to establish animal models of human imatinib-resistant GIST. The molecular and histopathologic features of GIST xenografts were also analysed and compared with their counterpart of cell lines.

RESULTSThe xenograft tumor models had been established by subcutaneously injection of GIST cells into nude mice. Immunohistochemistry results showed CD117 expression was positive in GIST-PR2 xenograft tumor, but negative in GIST-R. In GIST-PR1, tumor areas showing rhabdomyoblastic differentiation were presented next to areas with classic GIST morphology. The rhabdomyoblastic component demonstrated consistently positivity for desmin and myogenin, whereas CD117 was completely negative. The mutation profiles of these xenograft tumors were the same as their counterpart of cell lines.

CONCLUSIONSHuman GIST xenografts with mutation in c-kit have been established from imatinib-resistant GIST lines. Those models will enable further studies on mechanisms of resistance, combination therapies and allow testing of novel targeted therapies.

OBJECTIVETo investigate whether hypertension, abnormal lipometabolism, obesity, cigarette smoking and alcohol drinking affect the intracerebral hemorrhagic volumes (IHV) in patients with spontaneous intracerebral hemorrhage (SIHP), and to explore the roles of these factors in spontaneous intracerebral hemorrhage (SIH).

METHODSFive hundred patients with acute SIH and 200 healthy adult volunteers (HAV) were enrolled in a study of independently randomized controlled design, in which the levels of systolic pressure (SP) and diastolic pressure (DP), and total cholesterol (TCH), triacylglycerols (triglycerides, TG), high density lipoprotein cholesterol (HDL-CH), low density lipoprotein cholesterol (LDL-CH) in serum as well as the level of erythrocytic membrane cholesterol (EM-CH) were measured, and the body mass index (BMI), daily cigarette smoking consumption (DCSC) and daily pure alcohol consumption (DPAC) were calculated.

RESULTSCompared with the average parameters in the HAV group, those of SP, DP, TG, LDL-CH and BMI in the SIHP group were significantly increased (P < 0.0001), while those of HDL-CH and EM-CH were significantly decreased (P < 0.0001). The linear regression and correlation analysis showed that with increased SP, DP, LDL-CH, BMI, DCSC, DPAC and aging as well as decreased HDL-CH and EM-CH, the IHV levels in SIHP were increased gradually (P < 0.0001-0.01). The linear stepwise regression analysis suggested that there existed a close correlation among the values of SP, DP, TCH, TG, HDL-CH, LDL-CH, EM-CH, BMI, DCSC, DPAC, age and IHV of the SIH patients, and that Y = -12.4583 + 0.1127SP -1.1977EM-CH + 0.9788LDL-CH + 0.2477BMI + 0.0382DCSC + 0.0248DP, P < 0.0001 approximately 0.05.

CONCLUSIONSThe findings in the present study suggest that significantly increased systolic and diastolic pressure, low density lipoprotein cholesterol, body mass index and daily cigarette smoking consumption, and significantly decreased erythrocytic membrane cholesterol may be likely the main factors affecting intracerebral hemorrhagic volumes in patients with acute spontaneous intracerebral hemorrhage.
