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 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.

Objective To explore the therapeutic effect on the prevention of eccyesis by optimizing fallopian tube to be pregnant.Methods Three hundred and seventy-nine patients with infertility were divided into two groups:control group with 187 patients received the combined optimized treatment,and study group with 192 patients received the combined optimized treatment and optimizing fallopian tube to be pregnant.All patients received the hysterosalpingography uterosalpingography(HSU)whik the patients of the study group received the ultraphonic monitor for the.dominant follicle besides for 6 ovulatory cycle.Results There were intrauterine gestation 59 patients(31.55%,59/187),eccyesis 20 patients(10.70%,20/187)and infertility 108 patients(57.75%,108/187)in control group while there were intrauterine gestation 83 patients(43.23%,83/192),eccyesis 10 patients(5.21%,10/192)and infertility 99 patients (51.56%,99/192)in study group.The intrauterine gestation rate in study group was higher than that in control group(P<0.05),and the eccyesis rate was lower than that in control group(P<0.05).But there was no significant difference in the infertility rate between two groups(P>0.05).The eccyesis rate in fallopian tube unsmooth was higher than that in salpingemphraxis and fallopian tube canalization respectively[12.59%(18/143),2.63%(2/76),2.70%(2/74),P<0.05].Conclusion Selecting the optimizing fallopian tube by HSU and monitoring the dominant follicle by ultraphonic to guide pregnancy can let the dominant follicle grow and conceive in the optimizing fallopian tIlbe,and this treatment can raise the intrauterine gestation rate and decrease the cause of eccyesis.

Objective To explore the application of high frequency ultrasonography in the rapid diagnosis of irreducible radial head subluxation in children.Methods Twenty-three patients aged 1 to 5 with unilateral radial head subluxation in children were observed by high-frequency ultrasonography and radiography,and then compared the symptomatic to the contralateral side.Results No case of radial head subluxation was found by radiography.23 cases of radial head subluxation were found by high frequency ultrasonography,10 cases with articular cavity effusion.On the diagnosis of radial head subluxation in children,the sensitivity of high frequency ultrasonography was obviously higher than that of radiography.Conclusions The sensitivity of high frequency ultrasonography in the rapid diagnosis of the radial head subluxation in children is obviously higher than that of X ray film.High frequency ultrasonography through continuous scan can determine the continuity of anatomical structure and the relationship between some views to show the location of the specific structure relations.Specifically,it can be quickly and clearly diagnosed on anterior long-axis view and the lateral coronal view of radiohumeral joint.
