ObjectiveTo develop the military acute stress scale and examine the reliability and validity of this scale.MethodsBased upon the previous acute stress researches and the rule of psychometrics,the military acute stress scale was compiled according to open-ended inventory survey.A total of 630 personnel were chosen by random cluster sampling,and tested with this scale,50 of them were tested by Chinese Military psychosomatic health Scale simultaneously,and 50 of them were retested after two week.The reliability and validity were examined by exploratory factor analysis,confirmatory factor analysis and correlation analysis.ResultsThe military acute stress scale was comprised of 9 factors and one lie sub-scale ; Main fit indexes of model were the following CMIN =1219.476,DF =593,P =0.000,CMIN/DF =2.056,IFI =0.927,TLI =0.902,CFI =0.924,RMSEA =0.059; The conrelation coefficients between subscales and subscales were 0.284-0.572.The correlation coefficients between subscales and total scale were 0.700 ～ 0.846 (P ＜ 0.05 or 0.01 ) ; The correlation coefficients was significant between this scale and Chinese military psychosomatic health scale.The correlation coefficients were 0.338-0.962 (P ＜ 0.01 ).The test-retest correlation coefficients of total scale and subscales were 0.379-0.909 (P ＜ 0.01 ).The Cronbaeh's α coefficients were 0.606-0.926 ; and the split-half correlation coefficients were 0.466-0.855.ConclusionThe military acute stress scale has acceptable psychometrics properties on reliability and validity.

Objective:To study the surface enhanced Raman scattering ( SERS) of safflower and identify safflower injections by SERS quickly and effectively. Methods:Through comparative analysis of the Raman spectroscopy of safflower injections and the corre-sponding control herbs, the rapid identification of safflower injections was realized. Results:The results showed that several character-istic peaks of safflower were enhanced obviously in SERS, which could be used to identify safflower injections. Conclusion:The meth-od is reliable, rapid, accurate and specific, which can be applied as a method to identify safflower and its injections.

Venous thrombotic disease is a serious disease,which impact on health and life-threatening.Pulmonary embolism and deep-vein thrombosis are the two components of a single disease called venous thromboembolism in obstetrics and gynecology.but it can be difficult to diagnose because clinical symptoms and signs are non-specific or absent in early venous thrombus embolism (VTE).It has great value that how to use the most economic,simple,efficient method for screened high-risk groups,timely and accurate laboratory diagnosis of VTE.

Objective To observe the effect and safety of different doses of sufentanil plus subarachnoid block during labor. Methods One hundred parturients (single birth) were divided into 5groups by random digits table with 20 cases in each, which sufentanil 3,4,5,6,7 μ g in group A, B, C, D, E plus ropivacaine 3 mg were injected respectively into subarachnoid space. The onset and duration of subarachnoid analgesia were observed; visual analogue scale (VAS) were recorded respectively before injection and 5,15,30,60 min after injection; the vital sign,labor stage,labor type,adverse reactions of parturients,fetal heart rate (FHR) and the Apgar score at 1,5 min of neonate were recorded respectively.Results The onset of subarachnoid analgesia in group A was higher than that in group B,C, D,E;the duration of subarachnoid analgesia in group A,B was shorter than that in group C,D,E.VAS declined gradually 5,15,30,60 min after injection compared with before injection in 5 groups (P ＜ 0.01 );VAS in group B, C, D, E was lower than that in group A at 5 min after injection (P ＜ 0.05 ), and VAS in group C, D, E was lower than that in group A,B at 60 min after injection (P＜ 0.05). There was no significant difference in vital sign,labor stage,labor type,FHR and the Apgar score of neonate among 5 groups (P ＞0.05). The occurrence of itch of skin and nausea in group D,E [25%(5/20), 15%(3/20) in group D,and 40%(8/20),20%(4/20) in group E] was higher than that in group A, B, C [5%(1/20), 0 in group A, 10%(2/20), 0 in group B, 10% (2/20), 0 in group C] (P ＜ 0.05 ). Conclusion Subarachnoid block (sufentanil 4-6 μ g +ropivacaine 3 mg) can offer safety and efficacy of labor analgesia; sufentanil 5 μg is the best dose with subarachnoid block during labor at present.

Objective To detect the effects of chemotherapy on the immune function of patients with ovarian cancer.Methods Thirty-four patients with ovarian cancer(ovarian cancer group)who accepted chemotherapy were collected.Thirty healthy women were used as control group.The lymphocyte sub-cluster CD3+,CD4+,CD8+ and CD25+of peripheral blood were detected by flow cytometry.Results The peripheral blood CD3+,CD4+ and CD4+/CD8+ in ovarian cancer group were lower than those in control group(0.5524±0.1121 vs.0.6685±0.0869,0.3183±0.0864 vs.0.4139±0.0524,1.06±0.29 vs.1.43±0.21),CD4+ CD25+was higher than that in control group(0.1026±0.0418 vs.0.0287±0.0132),there was significant difference between two groups(P<0.05).There was no significant changes observed 1 week after chemotherapy(P>0.05).Three weeks after chemotherapy,the CD3+,CD4+ and CD4+/CD8+ in ovarian cancer group were higher and CD4+ CD25+ was lower,there were significant difference between two groups(P<0.05).Conclusions The ratio of lymphocyte sub-cluster is imbalance in the patients with ovarian cancer.Chemotherapy can improve the immunosuppression condition and recovery the ratio of lymphocyte sub-cluster in the patients with ovarian cancer.

Diffusion-weighted whole-body imaging with background body signal suppression(DWIBS) is a new magnetic resonance imaging technology.At present,it has not only been applied to screen and stage malignant tumors,but also to monitor therapeutic response and differentiate benign from malignant tumors.However,it still has certain disadvantages.This review described the current progresses in the potential applications of the DWIBS in malignant tumors.

Based on the analysis of the medical students' humanities quality and current college English teaching,this paper explored four strategies including pre-class lead-in activity,making full use of current teaching materials,reforming present college English teaching method and developing extracur-ricular practical activities in order to foster humanities quality in college English teaching and to improve medical students' humanities quality.

Necrotizing enterocolitis(NEC) is a common and devastating gastrointestinal disease that occurs predominantly in premature infants.Despite various advances in management,the mortality of this disease remains high.During the last decade,studies have shown that heparin-binding epidermal growth factor-like growth factor (HB-EGF),can protect intestinal epithelial cells from various forms of injury in vitro.Furthermore,studies using both an intestinal ischemia-reperfusion injury model in adult rats and neonatal rat model of NEC,have shown that HB-EGF can protect the intestines from injury.Present studies provide a new research direction in the prevention and treatment.

Objective:To observe the effect of intrapulpal injection in the pulpectomy of primary molars.Methods:22 petients with 44 diseased primary molars were divided into 2 groups(n =22 teeth).The intrapulpal injection with a computer-controlled local anesthetic delivery system STATM was performed in the experimental Group,and traditional infiltration anesthesia technique was conducted in the control group.Results:During the anesthesia process,the VAS value of the experimental group was lower than the control group(P ＜ 0.05).The pain control in the experimental group was better during pulp removal within 1 min.There was no occurrence of postoperative soft tissue numbness and factitial ulcer in the experinental group.Conclusion:The intrapulpal injection,administered with STATM,is more effective than traditional infiltration anesthesia in pulpectomy of primary molar teeth.

Objective To investigate the self-efficacy and other factors of the internship and discuss the effect of the self-efficacy in medical education.Methods Using the Face Scale,Trait Coping Style Questionnaire,General Self-efficacy Scale to measure the level of self-efficacy and other factors.Results Correlation was found between self-efficacy and other factors such as subjective well-being,positive coping style and professional stress.Conclusion The self-efficacy and other factors impact each other and reduce the professional satisfaction.
