Objective To develop stress vulnerability prediction scale for soldiers.Methods 148 items were determined by reviewing items in relating literatures and scales,interview,panel discussion and expert consultation.Then 431 and 351 soldiers in two times were picked out randomly as samples from Army Northwest District.Item analysis,exploratory factor analysis,reliability analysis and confirmatory factor analysis were used to analyse the data.Results Stress vulnerability prediction scale comprised five subscales:traumatic events,positive affect,negative trait,negative coping and interpersonal support.The scale was comprised of 59 items,and the factor loading of the items ranged from 0.503 to 0.839.Cronbach's α coefficient of the five subscales were 0.777,0.903,0.923,0.882,0.908,and the Cronbach's α coefficient of the scale was 0.895.Confirmatory factor analysis showed a higher goodness of fit(RESEA =0.058,NFI =0.89,NNFI =0.93,CFI =0.94,IFI =0.98).Conclusion Stress vulnerability prediction scale in soldiers has good psychometric properties,and can be used as a prediction measurement tool for measuring the stress disorder for soldiers.

Aim ToinvestigatewhethertheJAK2/STAT3 signaling pathway regulates prohibitin expres-sion to protect cardiomyocytes against hypoxia/reoxy-genation injury in hydrogen sulfide postconditioning. Methods Primaryculturedcardiomyocytesfromneo-natal rats were divided into 6 groups: control group ( Normal) , hypoxia/reoxygenation group ( H/R ) , hy-drogen sulfide postconditioning group ( NP) , hydrogen sulfide with AG490 group ( N + A ) , AG490 group ( AG) , DMSO group ( DMSO) . The survival percent-age of cardiomyocytes and the release of LDH were tested at pre-hypoxia and reoxygenation 2h. After reox-ygenation, cell apoptosis was detected by flow cytome-try. The expression of t-STAT3, p-SATAT3 and PHB were determined with Western blot analysis. Results No obvious changes were observed among the groups before hypoxia (P <0. 05). After reoxygenation 2h, compared with H/R group, NP group significantly im-proved the survival rate of cardiomyocytes ( P <0. 05 ) , inhibited the release of LDH and the myocardi-al apoptosis ( P <0. 05 ) , meanwhile up-regulated the p-STAT3 and PHB expression. However, AG490 abol-ished the cardioprotection offered by hydrogen sulfide postconditioning and the increase in p-STAT3 and PHB expression.Conclusion Hydrogensulfidepostcondi-tioning may protect cardiomyocytes against hypoxia/reoxygenation injury through the JAK2/STAT3 pathway upregulating the expression of prohibitin.

Objective To study the expressions of CA19-9 and CA125 and their clinicopathologic significances in gallbladder adenocarcinoma, pericancerous tissues and chronic cholecystitis. Methods EnVisionTM immunohistochemistry was used for assaying the expressive levels of CA19-9 and CA125 in the routinely paraffin-embedded sections of specimens from gallbladder adenocarcinoma (n=108), pericancerous tissues (n=46), and chronic cholecystitis (n=35). Results The positive rates of CA19-9 and CA125 were significantly higher in gallbladder adenocarcinoma (49.1%, 51.9%) than those in pericancerous tissues (26.1%, 15.2%) and chronic cholecystitis (14.3%, 5.7%), respectively (P

Objective To study the expressive levels of galectin-3 (gal-3) and sambucus nigra agglutinin(SNA) and to detect their clinicopathological significances in benign and malignant lesions of the gallbladder. Methods EnVisonTM Immunohistochemistry for assaying gal-3 expressive levels and ABC cytochemistry for determining SNA expressive levels were used in conventional paraffin-embedded sections from the specimens of adenocarcinoma (n = 108) , peritumoral tissues (n=46) . Adenomatous polyp (n=15), and chronic cholecystitis (n = 35). Results The positive rates of gal-3 and SNA were significantly higher in adenocarcinoma (62. 0%, 66. 7%) than in peritumoral tissues (39. 1%,45.6%), adenomatous polyp (26.7%, 33.3%) and chronic cholecystitis (11.4%, 11.4%)(P<0. 05 or P<0. 01). The positive gal-3 and SNA in benign cases showed atypical hyperplasia of the epthelium. The positive rates of gal-3 and SNA expression were significantly lower in well-differentiated adenocarcioma, mass with a maximal diameter of <2 cm, absence of lymph node metastasis,and absence of invasion to adjacent tissues than in poor-differentiated adenocarcinoma, mass with a maximal diameter of ≥2 cm, lymph node metastasis and invasion to adjacent tissues. (P<0. 05 or P<0. 01). There was a significant correlation between the expressive levels of gal-3 and SNA in gallbladder adenocarcinoma (x2=9. 51, P<0. 01). Conclusions The expressive levels of gal-3 and SNA lectins had important effects on carcinogenesis, progression and biologic behaviors of gallbladder cancer. Patients with positive gal-3 and /or SNA expressions had poor prognosis.

Background Congenital cataract is a major cause for blindness of childhood.Genetic gene mutation accounts for almost 1/3 of congenital cataract patients.The most common inheritance type is autosomal dominant congenital cataract (ADCC).Over 100 mutations in 26 genes have been found to be associated with ADCC.Objective This study was to identify the disease-causing gene mutation in a family with ADCC.Methods This study was approved by Ethic Committee of Beijing Tongren Hospital and followed Declaration of Helsinki.A northern Chinese family with autosomal dominant congenital nuclear cataract was entrolled in Beijing Tongren Hospital in January 2011.Ocular examinations were performed and periphery blood specimens were collected from each family member under the informed consent.Genomic DNA was extracted.Twenty-one microsatellite markers around 17 ADCC genes were selected for linkage analysis,and two-point LOD score was calculated.CRYGC gene and CRYGD gene were amplified and screened for mutations using direct sequencing.ProtScale software was used to analyze the changes of hydrophobicity of the mutated protein.Co-segregation of the observed change with the disease phenotype was further detected by restriction fragment length polymorphism (RFLP).Results This family included 20 members of 4 generations,and 9 patients were examined in serial 4 passages,which conformed to autosomal dominant inheritance pattern.Clinical examination revealed binocular congenital nuclear cataract in the 9 patients.Maximum two-point LOD score was 4.68 at marker D2S325 (θ=0).A known T→C change at position 127 of cDNA sequence was found by mutations screening of CRYGD gene.ProtScale programs showed an obvious increase of the local hydrophobicity in the mutant protein.RFLP results indicated that this missense mutation co-segregated with affected members of the family,but was absent in unaffected members and 100 unrelated controls.Conclusions c.T127C mutation of CRYGD gene appears to be the molecular pathogenesis of this ADCC family.Aberrant structure of mutant CRYGD protein caused by hydrophobicity change may lead to opacification of lens.

Objective To assess the characteristic of normal tension glaucoma (NTG) patients with mild cogni?tive impairment (MCI). Methods This study included twenty-six cases of normal tension glaucoma patients who were diagnosed at ophthalmology department of Peking University Third Hospital. All the participants were examined by us?ing the scales of Montreal Cognitive Assessment (MoCA), mini-mental state examination(MMSE), clinical dementia rat?ing (CDR), activities of daily living (ADL), Hamilton anxiety scale (HAMA), Hamilton depression scale (HAMD), Pitts?burgh Sleep Quality Index (PSQI) and polysomnography (PSG). The patients were then divided into Group with MCI (16 cases) and Group without MCI (19 cases). Results There was no difference between the two groups in gender, age, edu?cation, depression, anxiety and body mass index (BMI) (P>0.05), but significant difference in MoCA scores (P<0.05). The incidence rate of sleep disorder of PSQI in was 28.6%(10/35 patients) of total NTG patients, 43.8%(7/16 patients) in Group with MCI, and 15.8% (3/19 patients) in Group without MCI, respectively. The PSQI score was higher in Group with MCI than in Group without MCI (P<0.05). Sleep efficiency was higher in Group without MCI than in Group with MCI (P<0.05), but no difference was found between the two groups in six other indexes of PSQI (P>0.05). The in?cidence rate of sleep structure disorder of PSG in all the NTG patients was 85.7%(30/35 patients), 87.5%(14/16 pa?tients) in Group with MCI, and 84.2%(16/19 patients) in Group without MCI. Sleep time of NREM-N3 was significant?ly shorter in Group with MCI than in Group without MCI (P<0.05), but no difference was found between those groups in total sleep time, sleep efficiency, sleep latency and REM time (P>0.05). Conclusion NTG patients with mild cogni?tive impairment are more prone to sleep disorders, especially sleep structure disturbance and short NREM-N3 time may affect cognitive function.

Aim To explore the role of AMPK/ PGC-1α pathway in cardioprotection of hydrogen sulfide ( H2 S ) against ischemia/reperfusion ( I/R ) injury. Methods Langendorff perfusion apparatus was used to build an isolated rat myocardial I/R model. Seventy-two male SD rats were randomly divided into 6 groups (n=12):control group (Control), ischemia/reperfu-sion group ( I/R ) , DMSO group ( DMSO ) , inhibitor Compound C group ( CC) , H2 S postconditioning group ( NP) , and H2 S with Compound C group ( N +C ) . The heart rate ( HR ) , the left ventricular developed pressure ( LVDP ) , the maximum rate of increase or decrease of left ventricular pressure ( ± dp/dtmax ) and the left ventricular diastolic pressure ( LVEDP ) were registered at 20 min of baseline and 60 min of reperfu-sion separately. Triphenyl tetrazolium chloride ( TTC) staining and HE staining were used to determine the myocardial infarct size and the myocardial tissue mor-phological change of each group was observed respec-tively. Immunohistochemistry was used to determine the expression of PGC-1α. The expressions of total AMPK ( tAMPKα ) , phosphorylated AMPK ( pAMPKα) and PGC-1α were detected with Western blot anaylsis. Results There were no differences in e-quilibrium hemodyamics observed between the experi-mental groups(P>0. 05). At the end of reperfusion, compared with I/R group, NP group had obviously a-meliorated functional recovery and significantly de-creased myocardial infarct size [ ( 23. 9 ± 3. 4 )% vs (60. 9 ± 3. 8 )%, ( P <0. 05 ) ] . HE staining showed that in NP group, the myocardial injury was reduced. Meanwhile, the expression of pAMPKα and PGC-1αincreased significantly. However, Compound C re-versed the cardioprotection effects provided by hydro-gen sulfide postconditioning and reduced the expression of pAMPKαand PGC-1α. Conclusion AMPK/ PGC-1α pathway is involved in the role of hydrogen sulfide against ischemia/reperfusion injury.

Objective To explore the roles of p53 in ionizing radiation induced MCF-7 cell cycle uncoupling. Methods The p53 knock-down models was established in MCF-7 with retrovirus packaged particles from 293T cells through calcium acid phosphate co-precipitation, then Western blot was used to detect the protein expression. Flow cytometry(FCM) was used to analyze the cell cycle uncoupling and polyploid after irradiation. Results Compared with p53+/+ group, the percentages of G0/G1 cells in p53 -/- group decreased, while those of S and G2+M increased (P < 0.01). In polyploidy analysis 2N cells decreased, whereas both 4N and 8N cells =increased (P<0.01). Compared with sham-irradiation, 4 Gy X-ray led to the decrease of G0/G1, S cells, and the increase of G2+M cells. The increase of 2N cells and decrease of 4N and 8N cells were observed in both p53+/+ and p53-/- cells. Compared with p53+/+ +IR group, the decrease of G0/G1 and S cells and the increase of C2 + M cells were significant (P < 0.01) in p53-/-+ IR groups. 2N cells decreased, 4N cells increased, but no changes in 8 N cells occurred. Conclusion Radiation might induce G2 arrest and cycle uncoupling, p53 plays a role in the regulation of G2 arrest, but no role in cycle uncoupling.
