Objective:To explore the relation of fear of success to self-esteem,academic self-handicapping, and defensive pessimism in college students.Methods:Totally 291 college students were surveyed with the Self-Es-teem Scale (SES ),Academic Self-handicapping Questionnaire (ASHQ ),Defensive Pessimism Questionnaire (DPQ)and Fear of Success Questionnaire for Undergraduates (FOSQ).The structural equation modeling (SEM) and mediation analysis were used to test the hypotheses.Results:Self-esteem negatively predicted quality of life (β=-0.16),working pressure (β=-0.17)and interpersonal relationship (β=-0.14).In the 95% level of confi-dence,the lower range output of Bootstrapping in the path model of self-esteem through self-handicapping,defen-sive pessimism to a fear of success respectively was -0.29 and -0.14.The upper range output of those respec-tively was -0.14 and -0.01.Conclusion:Academic self-handicapping and defensive pessimism may play a medi-ating role in the relationship between self-esteem and fear of success.

To generate recombinant adenovirus expression vector of human Sema4C gene and observe its expression in mouse myoblasts cell line C2C12 for ensuring easy access to investigate the role of Sema4C gene during myogenesis. The recombinant plasmid was packaged and amplified after being transfected in HEK293 cells through Lipofectamine. After infecting C2C12 myoblasts with recombinant adenovirus vector, the adenoviral infection efficiency was determined by confocal microscope which showed that the expression of green fluorescence could be detected at 12h and then reached peak at 24h after recombinant adenovirus infection. The infection efficiency was almost 100% confirmed by FACS examination. Detection of WB indicated that the expression of Sema4C in C2C12 of recombinant adenoviral infection group was significantly higher than that of the control group (P

To explore the utility of apparent diffusion coefficient(ADC)histogram analysis for differentiating genetic subtypes of diffuse lower-grade gliomas. A total of 55 patients with WHO grade Ⅱ/Ⅲ diffuse lower-grade gliomas who underwent preoperative routine brain magnetic resonance imaging and diffusion weighted imaging in our center were retrospectively evaluated.Among whom there were 14 patients with isocitrate dehydrogenase(IDH)wild-type gliomas(IDH group),19 patients with IDH-mutant 1p19q intact gliomas(IDH 1p19q group),and 22 patients with IDH-mutant 1p19q co-deleted gliomas(IDH 1p19q group).The whole-lesion ADC values derived from histogram analysis(including ADC,ADC,ADC5%,ADC10%,ADC25%,ADC50%,ADC75%,ADC90%,ADC95%,ADC,mode,range,skewness,kurtosis,standard deviation,inhomogeneity,and entrophy)were measured for each patient.All parameters between the different genetic subtypes were compared by using the Student's test or Mann-Whitney test.Receiver operating curve(ROC)analysis was used to assess the diagnostic performance of ADC histogram in distinguishing the different genetic subtypes. Compared with IDH group,the ADC75%(=0.021),ADC90%(=0.015),ADC95%(=0.014),ADC (=0.035),range(=0.009),standard deviation(=0.001)and inhomogeneity(=0.001)were significantly lower in IDH group;in contrast,the ADC (=0.031)and kurtosis(=0.020)of IDH group were significantly higher than those in IDH group.The ADC(=0.010),ADC5%(=0.016),ADC10%(=0.012),ADC25%(=0.007),ADC50%(=0.005),ADC75%(=0.015),and mode(=0.002)were significantly higher in IDH 1p19q group than in IDH 1p19q group.Inhomogeneity achieved the highest area under ROC(AUC)(0.811)in differentiating IDH gliomas and IDH gliomas,with a cutoff value of 0.229;the sensitivity and specificity were 85.7% and 73.2%.The mode achieved the highest AUC(0.744)in differentiating IDH 1p19q gliomas and IDH 1p19q gliomas,with a cutoff value was 1448.75×10 mm /s;the sensitivity and specificity were 57.9% and 90.9%. ADC histograms analysis may be helpful to differentiate genetic subtypes in lower-grade gliomas.

OBJECTIVETo observe blood uric acid levels and Goldstein grading, as well as their correlation in Wilson's disease (WD) patients with different Chinese medical syndrome types.

METHODSTotally 906 WD patients in line with inclusive criteria were assigned to 6 groups, i.e., the heart spirit confused by phlegm group (HSCP, 26 cases), the phlegm-fire disturbing heart group (PFDH, 90 cases), the retention of damp-heat group (RDH, 113 cases), deficiency of qi and blood group (DQB, 168 cases), the deficiency of Gan-yin and Shen-yin group (DGYSY, 327 cases), the deficiency of Gan and Shen group (DGS, 182 cases) due to different Chinese medical syndrome types. Recruited were another 160 healthy subjects having similar ages and diet structures, who came for medical examinations, as the healthy control group. Venous blood was collected from the medial cubital vein of each-patient on an empty stomach in early mornings to detect blood uric acid levels. Results Blood uric acid levels were lower in each syndrome type group than in the healthy control group (146.08 +/- 67.24 micromol/L in the HSCP group; 157.08 +/- 69.77 micromol/L in the PFDH group; 162.58 +/- 97.72 micromol/L in the RDH group; 156.20 +/- 62.63 micromol/L in the DQB group; 161.83 +/- 111.23 micromol/L in the DGYSY group; 194.41 +/- 90.01 micromol/L in the DGS group; 242.39 +/- 87.55 micromol/L in the healthy control group, P < 0.01). Blood uric acid levels were higher in the DGYSY group than in the other 5 syndrome groups (P < 0.01). Correlation analyses between Goldstein grading and blood uric acid showed that, along with increased Goldstein grade (that was aggravating disease conditions), WD patients' blood uric acid levels decreased (P < 0.01).

CONCLUSIONSWD patient's blood uric acid levels decreased more. Blood uric acid levels and Goldstein grading were different in various Chinese medical syndrome types. Blood uric acid levels had certain value in assessing the severity of WD.

ObjectiveTo evaluate the curative effect difference between Tong's anterior mesh suspension and modified tension-free vaginal tape-obturator (TVT-O). Methods75 SUI cases were random divided into two groups: Group A (35 cases) were accepted Tong's anterior mesh suspension and group B (40cases) were accepted modified tension-free vaginal tape- obturator. Curative effects, operation safety,and complications and so on, were recorded and compared. ResultsThere had no statistical differences between these two groups on operation time, bleeding lose, operation injury, immediate postoperative urinary retention andcure rates, but the operation expense of group A was cheaper than group B [ (980. 74 ±212.45)yuan vs (2879.06 ±467. 13)yuan , P ＜0.05). ConclusionThe curative effect between two methods were similar. It's a little complicated and fit to be popularized in large hospital to modified tensionfree vaginal tape-obturator. Tong's anterior mesh suspension was performed under completely direct vision,not through pelvic cavity, and it was an economic, convenient and easy way, which not only fit to be popularized in basic hospital, but also a surgical remedial measure to the failures who accepted these operations,such as TVT, SPARC, IVS, MONARC, TOT, TVT-O, etc.

OBJECTIVETo investigate the relationship between Arg778Leu/Gln gene mutation spot in ATP7B and TCM Syndrome type in Chinese patients with Wilson disease (WD).

METHODSExon 8 of ATP7B of 90 WD patients and 30 healthy controls were amplified by PCR and analysed by restriction enzyme Msp I, the TCM Syndrome type of the patients was differentiated at the same time.

RESULTSIn the 90 WD patients, 34 with Arg778Leu/Gln of exon 8 were detected, among them 20 cases belonged to the TCM Syndrome type of endogenous Liver-Wind agitation.

CONCLUSIONOnset age of WD patients with Arg778Leu/Gln mutation is later than that without this mutation. Arg778Leu/Gln mutation might be related to the TCM Syndrome type of endogenous Liver-Wind agitation.
