Objective To investigate personality characteristics and its correlation with academic performance of vocational nursing students.Methods 153 nursing students were asked to filled out the questionnaire of Chinese College Student Personality Scale(CCSPS).The results were analyzed by 13.0 SPSS.Results Nursing students concentrated in the middle-up level in all the seven dimensions of the T-norm.The mean of directness,sensation and amiability were higer than the T-norm; The mean of tenaciousness and altruian were lower than the T-norm; There were different levels of correlation between academic performance and the four dimensions including directness,tenaciousness,rigorousness and amiability(P＜0.05).Finally only the dimension of rigorousness entered into the regression equation of academic performance.Conclusion Vocational nursing students tend to have ordinary personalities.The dimension of rigorousness is the major factor influencing vocational nursing students' academic performance.So it should be targeted to promote vocational nursing students' personality perfection.

OBJECTIVE To analyze the incidence of anatomic variations of the temporal bone to provide valuable reference for clinical otology. METHODS Sev-enty six healthy adults (152 ears) and 66 patients(96 ears) with chronic suppurative otitis media confirmed by clinical examination underwent axial and coronal High-resolution Computed Tomography(HRCT) scan. The incidence of high jugular bulb, dehiscent jugu-lar bulb, anterior location of sigmoid sinus, low-lying middle cranial fossa, dehiscent tegmen tympani, mas-toid antrum dysplasia, aberrant internal carotid artery, and large sinus tympani were recorded. RESULTS In normal, abnormal, well and poorly pneumatized groups, the incidence of highly positioned jugular bulb on the right was higher than that on the left. The total inci-dence of high jugular bulb on the left and right was 26.2 % and 46.0 % respectively. The incidence of ante-rior location of sigmoid sinus in the abnormal group (32.3 %) was higher than that in normal group(15.8 %), which was higher in poorly pneumatized group(43.5 %) than that in well pneumatized group(11.3 %). The inci-dence of dehiscent tegmen tympani in well pneuma-tized group(18.0 %) was higher than that in poor pneu-matized group(8.7 %). There was no significant differ-ence in dehiscent jugular bulb, low-lying middle cranial fossa, mastoid antrum dysplasia, aberrant internal ca-rotid artery, and large sinus tympani between the left and right within and among groups. The incidence of these varia-tions was 2.0 %,21.8 %,1.2 %,0.4 %,0.8 %respectively. CONCLUSION HRCT can show ana-tomic variances of temporal bone clearly before opera-tion and has great clinical value for reducing the inci-dence of complications caused by middle ear operation.

Objective To explore the role of plasminogen activator inhibitor-1(PAI-1)in development of progressive fibrosis via the inhibition of extracellular matrix degradation,and to reveal the contributive role of PAI-1 in muscular dystrophy(MD).Methods Expression and cellular localization of PAI-1 protein were examined in frozen muscle specimens obtained via biopsy from 5 patients with duchenne muscular dystrophy(DMD),3 patients with becker muscular dystrophy(BMD),9 patients with congenital muscular dystrophy(CMD) and 4 cases with normal muscle by immunohistochemistry,double immunofluorescence and Western-blot analysis.Results PAI-1 was positive only in vascular endothelial cells of normal muscle.Both immunohistochemistry and Western-blot analysis showed that PAI-1 expression distinctly increased in most dystrophic muscles of MD than that in normal muscles.Double immunolabeling revealed that PAI-1 strongly expressed in cytoplasm and nuclei of regenerating muscle fibers,macrophages,macrophage infiltrating necrotic fibers.Some activated fibroblasts in endomysium and perimysium of DMD and CMD muscles were positive for PAI-1.Conclusions The functional consequence of overexpression of PAI-1 in dystrophic muscles is unknown but the elevated local expression of PAI-1 in diseased muscles of MD and their distinct distribution pattern provide evidence that PAI-1 participate in pathogenesis of MD.

With the Meta-analysis method, the clinical efficacy of acupuncture and other regular methods for aphasia was evaluated, and the acupoints selection for aphasia was explored. The acupuncture literature of clinical randomized control trials for aphasia published in CNKI, WANFANG, VIP and CBM database was searched; the statistical analysis of clinical efficacy of acupuncture and other regular methods for aphasia was performed by using software Revman 5. 2 provided by Cochrane library. A file of Microsoft Excel was established to perform the analysis of acupoints selection based on frequency analysis method, so as to summarize the characteristics and rules. Totally 385 articles were searched, and 37 articles those met the inclusive criteria was included, involving 1,260 patients in the acupuncture group and 1 238 patients in the control group. The Meta-analysis results showed OR = 3.82, 95% Cl [3.01, 4.85]; rhombus was located on the right side and the funnel plot was nearly symmetry, indicating the treatment effect of the acupuncture group for aphasia was superior to the control group (Z = 11.04, P < 0.000 01). The frequency-analysis results showed that the frequency of acupoints from top to bottom was Lian-quan (CV 23), Tongli (HT 5), Yamen (GV 15), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20), Yuyan II, Yuyan I and Yuyan III. The frequency of meridians from top to bottom was the governor vessel, extra channels, conception vessel, heart meridian and large intestine meridian. It is concluded that the clinical efficacy of acupuncture combined with speech rehabilitation training and medication treatment for aphasia is superior to that of speech rehabilitation training and medication treatment alone. The clinical treatment for aphasia focuses on its local effect; the main acupoints are in the head and face, and the meridians are governor vessel, extra channels and conception vessel.
