AIM Analyze on characters of self-consistency and congruence of air force pilots and its in-fluential factors,so as to provide a background for counseling and psychotherapy.Methords Altogether 428 air force pilots were evaluated in our sanatorium using Self Consistency and Congruence Scale,Life Events Scale,Per-ceived Social Support Scale,Social Avoidance and Distress Scale,Trait Coping Styles Questionnaire,Eysenck Per-senality Questionnaire for Adults and Symptom Checklist 90.Results Self-inconsistent and incongruent and self stiffness of air force pilots were lower than that of army force (-13.10≤t≤-2.45,P<0.05) ;but self flexibil-ity was higher (5.11≤t≤11.98,P<0.01) ;the correlation between self-inconsistent and incongruent and the neuroticism of EPQ was good (0.406≤r≤0.529,P<0.001) ;the correlation between self-inconsistent and in-congruent and all the factors of perceived social support were goed(0.212≤r≤0.377,P<0.01) ;the correlation between it and negative family events was good (r=0.445,P<0.01) ;the correlation between self-inconsistent and incongruent as well as self stiffness and negative coping style was good (r=0.595,0.434,P<0.01);also and social distress was also good(r=0.456,P<0.01);then the result of the multiple factors analysis revealed that : the first reason that affect the self-inconsistent and incongruent of air pilots was negative life events β=0.53;and the second reason was mentality ill health β=0.40.Conclusion The self-consistency and congruence of air force pilots can be improved by replying the negative life events and enhancing mentality health.

Objective To investigate the effects among social mature,mental health and marriage quality of pilot's couples. Methods SCL-90,EPQ and ENRICH were conducted in 288 of pilot's couples. Correlation,regression were analyzed with SPSS 15.0 software. Results The marriage quality of pilot was significantly affected by the social mature and mental health of pilot himself(β=0.203,-0.274,P<0.001);meanwhile the marriage quality of pilot's wife was significantly affected by the mental health of pilot's couples(β=-0.276,-0.185,P<0.01). Conclusion The social mature and mental health of pilot's couples has a great influence in their marriage quality,so the social mature and mental health of pilot's couples should be taken into the system of the psychological counseling and therapy for pilots.

Objective Through the conversion of civil passenger cars, to develop mobile psychological counseling and treatment centre that can afford field operation for our pilot. Methods The internal structure of 28-Seat-MQ6798 type King Dragon bus was rebuilt by installation of equipment related to psychological intervention, the development of psychological intervention plans, the broad participation of military exercises, force of mental health and education, the actual of sudden catastrophic events, and according to the verification results, field psychological counseling and treatment vehicle and psychological intervention plans were verified. Results The field psychological counseling and treatment centre exclusively includes anterior cabin, hinder cabin, storage rooms and psychological testing and psychological intervention equipment, which can be constituted not only the exchange platform of psychological block aid and information exchange on wartime, popularizing mental health knowledge for officers and soldiers at ordinary times, but also the intervention platform of catastrophic events, anti-terrorism and appeasing confusion and violence. Conclusion The field ambulance is necessary for keeping the mentality health of pilots under the wartime in the future.

Objective To explore the pathway relationship among self consistency and congruence,life events and mental health,and to supply dependable data to psychotherapy and counseling about pilots.Methods Altogether 428 air force pilots were evaluated in air force Hangzhou sanatorium using self consistency and congruence scale (SCCS),life events scale(LES)and symptom checklist 90 (SCL-90).Spearman correlation analysis, one-sample t-test analysis and pathway analysis were used by soft package for social science version 15.0(SPSS 15.0)and AMOSv7.0.Results The results showed that there were significant relationships between all factors of self consistency and congruence and some factors of stressful life events(r=0.134～0.445);there were significant relationships between all factors of self consisteney and congruence and all factors of SCL-90(r=0.110～0.446); and negative life events of family,negative life events of work and negative life events of social communication were all had highly significant relationships with all factors of SCL-90(r=0.248～0.628).The pathway coefficient between life event and mental health Was B=0.39,P<0.01.The pathway coefficient among self consistency and congruence, life event and mental health were B=0.38,B=0.35,P<0.01,and the total adjust effects was 13.3%.Conclusion Self consistency and congruence is a important adjust variable between life events and mental health, can lighten the impact between life events and mental health.

Objective To compare the short and long term effect of knee osteoarthritis treatment with two therapeutic methods which are simple high cut of fibula and arthroscopic lavage debridement combined with fibular osteotomy.Methods Data of 45 consecutive patients with knee osteoarthritis were retrospectively observed and selected,and then they were divided into two groups according to the operation method.23 patients with simple high cut of fibula were selected as the control group,and 22 patients with arthroscopic lavage debridement combined with fibular osteotomy were selected as the observation group.Results The VAS and AKS scores of the control group at the time of 3m,6m,1 2m were (4.1 3 ±0.76)points,(1 07.04 ±21 .53)points;(2.70 ±0.64)points,(1 41 .1 7 ±1 2.57)points;(2.43 ±0.79)points,(1 48.26 ±5.81 )points;and the scores of the observation group were (3.45 ± 0.60)points,(1 26.64 ±1 4.24)points,(2.70 ±0.73)points,(1 46.45 ±7.26)points,(2.41 ±0.85)points and (1 48.26 ±5.81 )points.The differences between the two groups were statistically significant at the time of 3 months after surgery(t =3.32,-3.62,all P <0.05),the effect of observation group was better than the control group;but the other indices had no statistically significant differences (t =0.51 ,-1 .72,0.1 1 ,-0.20,all P >0.05 ). Conclusion The simple high cut of fibula with small trauma,less cost,less surgical difficulty,and long -term clini-cal curative effect is not less than the arthroscopic lavage and debridement combined with fibular osteotomy.There-fore,it should be carried out in the primary hospitals widely.

AIM: Construction of an eukaryote- E. coli shuttle expressing recombinant plasmid which expresses OmpL1 envelope protein of pathogenic Leptospira, serovar Lai strain 017. METHODS: The OmpL 1 gene was amplified by PCR from the leptospiral genome. Then it was cut with restriction enzymes and ligated to the plasmid pBK-CMV. The correct recombinant plasmid was screened out with analysis of restriction enzymes and PCR. After inducing the E. coli baring recombinant plasmid with IPTG,the complete protein of the bacteria was extracted for SDS-PAGE. At the same time, OD600 of the host bacteria was examined at different time after inducing or uninducing with IPTG. RESULTS: Five strains E. coli containing proper recombinant plasmids were screened out. Four strains E. coli expressed a new protein with a weight of 37 kD among them. With the expression of the heterogenous protein,the OD600 of the host bacteria decreased. CONCLUSION: The shuttle expressing plasmid of the OmpL 1 gene of strong virulent Leptospira strain 017 was successfully constructed. Furthermore,the recombinant plasmid expressed the expected OmpL 1 fusion protein in E. coli and the expression of the heterogenous protein had toxic effect on the host bacteria. This work was important for the future research of OmpL1 protein which relates to the diagnosis,new vaccine preparing and the pathogenic mechanism of leptospirosis.

Forty three patients with L5-S1 spondylolisthesis undergoing surgical treatment from April 2012 to November 2014 were included for analysis,including 20 cases received transforaminal lumbar interbody fusion (TLIF group) and 23 cased received posterior lumbar interbody fusion (PLIF group).The incision length,operative time were shorter and blood loss was less in TLIF group than those in PLIF group [(9.6±0.9) vs.(16.1±1.5) cm,(125.6±13.0) vs.(156.4±11.8) minand (218.7±22.5)ml vs.(326.5 ±20.1) ml,respectively,all P =0.000].There was no statistical difference in the S1 pedicle screw (S1PS) insertion point between two approaches[(29.4 ± 1.9) vs.(28.5 ± 1.0) mm,P =0.069],but the distance from the midline to the lateral edge of the screw (12.9 ±3.6) mm,S1PS angle (23.3 ±2.1) ° and length of S1PS length with the sacral body (40.9 ± 2.6) mm in the TLIF group were better than those in PLIF group (P =0.000).Our results demonstrate that the paraspinal muscle approach for the treatment of L5-S1 spondylolisthesis may be superior with less trauma,better functional recovery and stable screw placement.

Objective:To validate five-year risk prediction models for atherosclerotic cardiovascular di-sease (ASCVD) in a contemporary rural Northern Chinese population.Methods: Totally 6 489 rural adults aged 40 to 79 years without clinical ASCVD were enrolled at baseline between June and August 2010, and followed up through January 2017.Expected prediction risk using the China-PAR (prediction for ASCVD risk in China) model was compared with the pooled cohort equations (PCE) reported in the American College of Cardiology / American Heart Association guideline.Kaplan-Meier analysis was used to obtain the observed ASCVD event (including nonfatal myocardial infarction, coronary heart disease death, nonfatal or fatal stroke) rate at 5 years, and the expected-observed ratios were calculated to eva-luate overestimation or underestimation in the cohort.The participants in the cohort were divided into 4 categories (<5.0%, 5.0%-7.4%, 7.5%-9.9%, and ≥10.0%) for comparisons based on ASCVD prediction risk.The models were assessed by discrimination C statistic, calibration χ2, and calibration charts and plots for illustration as well.Results: Over an average 5.82 years of follow-up in this validation cohort with 6 489 rural Chinese participants, 955 subjects developed a first ASCVD event.Recalibrated China-PAR model overestimated ASCVD events by 22.2% in men and 33.1% in women, while the overestimations were much higher for recalibrated PCE as 67.3% in men and 53.1% in women.Gender-specific China-PAR model had C statistics of 0.696 (95%CI, 0.669-0.723) for men and 0.709 (95%CI, 0.690-0.728) for women, which were similar to those of 0.702 (95%CI, 0.675-0.730) for men and 0.714 (95%CI, 0.695-0.733) for women in the PCE.Calibration χ2 values in China-PAR were 17.2 and 54.2 for men and women, respectively;however, the PCE showed poorer ca-libration (χ2=192.0 for men and χ2=181.2 for women).In addition, the calibration charts and plots illustrated good agreement between the observations and the predictions only in the China-PAR model, especially for men.Conclusion: In this validation cohort of rural Northern Chinese adults, the China-PAR model had better performance of five-year ASCVD risk prediction than the PCE, indicating that recalibrated China-PAR model might be an appropriate tool for risk assessment and primary prevention of ASCVD in China.

BACKGROUNDTo study the correlation among the number of tumor-infiltrating dendritic cells (TIDC) in cancer tissues and biological behavior and prognosis in lung cancer patients.

METHODSS-100 protein expression level was determined in 39 patients with lung cancer by immunohistochemistry technique. The number of S-100 + TIDC and DNA ploidy were measured by means of flow cytometry.

RESULTSThe rate of positive S-100 protein expression was 100% in 39 patients, S-100 + cells showed typical morphology of dendritic cells. The percentage of S-100 +TIDC in patients with heteroploid (21.81%±8.18%) was significantly higher than those with diploid (16.03%±4.75%) (P=0.006). There was no statistical difference between lymph node metastasis group (20.43%±7.74%) and no lymph node metastasis group ( 19.41% ±7.76%), between tumor size greater than 3cm group ( 20.90% ±8.65%) and less than 3cm group ( 19.70% ±7.61%), between non-small cell lung cancer group (19.48%±7.98%) and small cell lung cancer group (21.74%±6.17%). No correlation was found between survival time ( 1 year , 1-3 years, greater than 3 years, respectively) and percentage of S-100 +TIDC (21.96%±8.05%, 19.47%±6.18%, 19.14%±8.76%, respectively).

CONCLUSIONSThe number of TIDC should not be chosen as an independent prognostic criterion in human lung cancer.
