AIM: To investigate the clinical significance in determination of the P- selectin levels in subjects with prethrombotic state or thrombosis by flow cytometry (FCM). METHODS: The P- selectin expression on platelet membrane in 42 patients with diabetes mellitus, 33 with hyperlipidemia, 23 with cerebral infarction and 20 healthy individuals, were analyzed using fluorescently - labeled SZ - 51 by direct FCM comparing with indirect FCM and enzyme- linked immunosorbent assay (ELISA). RESULTS: The level of P- selectin on platelet membrane is higher in DM (23.92 % + 15.83 % ), in hyperlipidemia ( 18.34 % + 9.46 % ) and in cerebral infarction ( 19.32 % + 10.38 % ) than normal subjects (3.38 % + 1.11% ) ( P < 0.01 ). In addition, similar results on P - selectin were obtained by indirect FCM and ELISA in patients with DM and cerebral infarction. CONCLUSION: FITC - labeled SZ - 51 - IgG can be used in FCM, and it would be a new and sensitive method in detecting platelet activation.

Objective To evaluate HSP90 levels in the diagnosis and staging of gastrointestinal tumors.Method Patients with gastrointestinal tumors hospitalized from 2014 January to 2015 April were enrolled in this study.Serum level of HSP90 was detected.Results The serum HSP90 level of cancer group(112 ± 74)was significantly higher than the control groups,the area under the ROC curve of HSP90's was 0.875 and the cut-off point was 63.63 with sensitivity of 76.1％ and specificity of 92.6％.The HSP90 level in gastric cancer group(135 ±73)ng/ml was the highest,in colon cancer group was (105 ± 60) ng/ml and in rectum cancer group was(79 ± 42)ng/ml (all P ＜ 0.05).Serum HSP90 levels in moderate and low differentiated adenocarcinoma were higher than well differentiated adenocarcinoma group (P ＜ 0.05).Serum HSP90 level was higher in tumors with submucosa and serosa infiltration (P ＜ 0.05).Those with lymphatic metastasis tend to have a higher serum HSP90 level than those without.Conclusion Serum HSP90 level has a good predictive value on gastrointestinal tumor diagnosis,and it is correlated with tumor staging and infiltration status.

Objective To investigate the clinical value of high frequency ultrasound in discovering secondary pathological changes in infant with developmental dysplasia of the hip (DDH).Methods Thirtyfour infants with 36 dislocation hips were involved.Among them,32 were with unilateral dislocation of hip joint,2 were with bilateral dislocation of hip joint.High frequency ultrasound were used to observe the morphological changes of hip glenoid labrum,adipose hyperplasia in acetabulum,thickness variation of articular capsule,and development of the ossification center of the femoral head.Besides,the morphological changes of hip glenoid labrum and adipose hyperplasia in acetabul were compared with those from MRI.Results The sensitivity and specificity of ultrasound in diagnosing glenoid labral introversion were 82 ％ and 100％ respectively.The coincidence rate of diagnosing glenoid labral introversion and glenoid labral extroversion were both 83％.Adipose hyperplasias in acetabul were clearly seen in 31 hips using ultrasound.The thickness of articular capsule in the affected hip and in the healthy hip was (2.8 ± 0.6)mm versus (1.7 ± 0.4) mm,and the difference was obviously significant (P ＜0.01).The ossification center of the femoral head in the 34 infants were classified as the following four types:① which was smaller in the affected side than in the healthy side (22/34);②which was shown in the healthy side (7/34) but not in the affected side;③ which in both sides were not shown (4/34);④ which in both sides were small (1/34).Conclusions Ultrasound is a method of simple,rapid,non-invasive in diagnosing DDH,and it can be used to discover secondary pathological changes in infant with DDH,which provide important reference for clinical diagnosis and treatment.

Objective To evaluate a new enzyme-linked immunospot assay (TSPOT-TB) for the diagnosis of latent tuberculosis infection in patients with rheumatic diseases.Methods The rapid TSPOT-TB assay was applied to detect ESAT-6 and CFP-10 specific T cells in blood samples from 126 rheumatic disease patients.A PPD skin test was performed on all patients simultaneously.Results The positive rate of TSPOT assay was 23.8% and that of PPD skin test was 34.9%.The overall agreement between the 2 tests was 71.4%.Among PPD (-) patients (n=82),11 were TSPOT (+) ( 13.4% ).Among PPD (+) patients (n=44),25 were TSPOT(-) ( 56.8% ).The patients who got BCG vaccination showed a significantly higher rate of positive results of PPD skin test than those who did not(41% vs 19%,P＜0.05).While in TSPOT assay,the BCG vaccination did not show any influence on TSPOT results (22% vs 27%,P＞0.05).Conclusion BCG vaccina-tion affects the results of PPD test in patients with rheumatic diseases,but has no influence on TSPOT results.The infection rate of latent tuberculosis in patients with rheumatic diseases in our study is 23.8% detected by TSPOT.

Objective To explore the mental health and its relationship with mental quality of training logistic soldiers in field.Methods Symptom Checklist 90(SCL-90) and Mental Quality Questionnaire for armymen (MQQA) were employed to evaluate the mental health and mental quality of 230 training logistic soldiers in field,and then an analysis was carried out on the characteristics of the training logistic soldiers on mental health and its relationship with mental quality.Results ①The psychological problem's ratio of training soldiers was 21.3％,and the ratio of the male(22.8％) was significantly higher than that of the female(15.2％) (x2 =8.64,P=0.00).In SCL-90,the scores of somatization (1.46 ± 0.63),hostility (1.49 ± 0.75) and psychotism (1.43 ±0.68) were all higher in training soldiers than the army norm.The factor scores of somatization (1.49 ± 0.66)and psychotism(1.46 ± 0.72) in the male training soldiers were considerably higher than those of the male soldiers norm (P ＜ 0.05),but not in the female(P ＞ 0.05).②There existed a significantly negative correlation between the factor scores of the mental quality and that of SCL-90 (P ＜ 0.05,P ＜ 0.01).③The SCL-90 scores existed clear differences in obsessive-compulsive,interpersonal sensitivity,depression,hostility and paranoid ideation among different mental quality groups (P ＜ 0.05).Conclusion The mental health of training logistic soldiers is poor.The mental health is closely related to the mental quality.Therefore,the mental health education and mental quality training should be strengthened to the training logistic soldiers.

Objective To explore the effects of group psychological training on mental health of military students and field soldiers.Methods A total of 60 students and 48 soldiers received group psychological quality training and studied a textbook Mental Quality Training for armymen for 3 months.Mental Quality Questionnaire for Amymen (MQQA),Symptom CheckList 90 (SCL-90),Self-rating Anxiety Scale (SAS),Self-rating Depression Scale (SDS) and State-Trait Anxiety Inventory(STAI) were employed to evaluate mental health and psychological quality of subject before and after the training.All the data were analyzed by independent-samples t test.Results (1) The difference in MQQA score of field soldiers before and after training was significantly larger than that of military students in loyalty and general score,and lower in willpower((-16.58 ± 7.75) vs.(-1.75 ± 8.68),(-27.74 ± 28.74) vs.(-12.57 ± 30.96),P ＜ 0.05).(2) The SCL-90 difference of field soldiers between before and after training was significantly larger than that of military students in hostility and phobic anxiety((0.26 ±0.47) vs.(0.07 ± 0.24),(0.13 ± 0.40) vs.(0.02 ± 0.13),P ＜ 0.05).(3) The difference in emotion score of field soldiers between before and after training was significantly larger than that of military students in SAS,SDS,SAI,TAI and STAI (P ＜ 0.01).Conclusion The effects of group psychological quality training on field soldier group are better than that of military students,which is helpful to improve mental quality and mental health,as well as to relax anxiety and depression of soldiers.

Objective To compare the efficacy of the conventional PPD skin test and a new enzymelinked immunospot assay(TSPOT-TB)for diagnosing latent tuberculosis infection(LTBI)in patients with rheumatic diseases.Methods Two hundred and sixty rheumatic patients were enrolled,and all were screened for LTBI based on clinical history,chest X-ray,PPD skin test or TSPOT.Results The positive rate of TSPOT assay was 24.1%and that of PPD skin test was 39.4%.The overall concordance rate between the 2tests was 61.0%.Among PPD negative patients (n=149).29 were TSPOT(+)(19.5%).Among PPD(+)patients(n=98),69 were TSPOT(-)(70.0%).The patients who got BCG vaccination or had history of tuberculosis infection showed a significantly higher rate of positive result of PPD skin test than those who did not (P<0.05 or P<0.01).While in TSPOT assay,the BCG vaccination or history of tuberculosis infection did not show influence on TSPOT results(P>0.05).Of the 127 patients who received biological agents after screening for LTBI,9 patients were pretreated with isoniazide.Twenty-seven patients stopped biological agent treatment because of the positive results of PPD or TSPOT.Twenty three patients who had positive PPD but negative TSPOT results received biological agent treatment without isoniazide,and none of them developed active tubereulosis after 6 to 18 months of follow-up.Conclusion BCG vaccination affects the result of PPD test in rheumatic patients,but has no influence on TSPOT results.The infection rate of latent tuberculosis of rheumatic patients in our research is 23.8%detected by TSPOT.
