Objective:To evaluate the diagnosis of fat embolism syndrome(FES)imagings in the chest with Spiral CT.Methods:To analyze 5 cases FES which had been proved by clinical diagnosis,all had received Spiral CT scanning,among which 3 cases had X-ray chest plain films done.Results:Chest CT imagings showed bilateral multiple patchy and ground-glass opacity imagings in 3 cases,diffuse 2 cases,pleural effusion in 2cases.X-ray chest plain films showed the lung markings increased in 2 cases,normal in 1 case.Conclusion:Bilateral pulmonary diffuse multiple-patchy or "snowstorm" changes in the chest were the typical CT imagings after the multiple-bone fractures complicated by FES.It can provide evidence directly for FES with Spiral CT,earlier diagnosis of FES in the chest scanning can help clinical therapy and evaluate prognosis.

Objective:To evaluate the imaging findings and differential diagnosis of pancreatic stones(PS).Methods:18 patients hospitalized undergoing surgical therapy during 1991-2001 were studied retrospectively,and their imaging findings analyzed.Results:(1)PS were along with pancreatic duct in company with pancreatic duct high dilatation and the maximum PS were in pancreatic head.(2)PS was seen 100% on CT.CT can find PS combined with other complications.(3)PS are different from pancreatic calcinosis.Conclusions:(1)Ultrasonography was the first choice for cxamination.It is valuablc to usc CT to cstablish diagnosis and display complications for designing preoperation strategy.(2)Patient with definite diagnosis of PS should undergo early operation.

Objective: To explore the effects of Qingshi Cream, a compound traditional Chinese herbal medicine, on chronic dermatitis-eczema in mice induced by 2,4-dinitrochlorobenzene (DNCB). Methods: Thirty BALB/C mice were randomly divided into vaseline group, 0.1% mometasone furoate cream group and Qingshi Cream group. Right ears of BALB/C mice were repeatedly challenged with 0.1% DNCB every three days for five times and previously sensitized with 7% DNCB to induce chronic dermatitis-eczema. Mice in different groups were applied Qingshi Cream, 0.1% mometasone furoate cream and vaseline respectively after each challenge. Weight difference of two ears, pathological change of right ear and dermal inflammatory cell number were used to assess the effects of the drugs. Results: After the 5th challenge, weight differences of two ears in the 0.1% mometasone furoate cream group and the Qingshi Cream group were significantly decreased as compared with that in the vaseline group. Changes such as ear swelling thickening and cellular infiltration in dermis were observed, and these features seemed to be more significant in the vaseline group as compared with the 0.1% mometasone furoate cream group and the Qingshi Cream group. Conclusion: Qingshi Cream has an obvious effect in treatment of chronic dermatitis-eczema in mice.

Objective To analyze the screening and confirmation test results of human immunodeficiency virus (HIV) antibody during 2009-2015 to provide the basis for the recruiting strategies in recruiting blood donors among the low risk population and blood donor′s returning to the team .Methods The blood samples of voluntary blood donors were detected the HIV antibody by the ELISA method ,with the reagents provided by 2 different manufacturers .The samples of HIV antibody positive or suspected sam‐ples were submitted to the Shenzhen Municipal Center for Disease Control and Prevention CDC for conducting the Western blot confirmation .The confirmation results of blood samples during 2009 -2015 were statistically analyzed .Results There were 197 766 blood samples from 2009 to 2015 .The overall infection rates of HIV were 1 .3 ,4 .7 ,5 .6 ,5 .4 ,5 .3 ,4 .6 ,7 .3/one hundred thousand respectively ,the average infection rate was 0 .004 9% (4 .9/one hundred thousand) ,the average confirmed positive rate was 22 .1% ,the false positive rate was 77 .9% .Among the blood donors of confirmed positive HIV antibody ,the donors aged 18-30 years old accounted for 67 .7% .Conclusion It is important for the recruitment work before the blood donation .Aiming at the blood donors of workers from outside and relative low cultural level ,especially the blood donors of high risk behavior ,the small card mode could be adopted to guide them to the disease control center to conduct the professional consultation and detection ,which can increase the blood transfusion safety coefficient and also prevents the spread of HIV/AIDS .Aiming at the false positive blood do‐nors ,the works of follow up ,tracking monitoring and return to the blood donation team should be done well for reducing the run a‐way of blood donors .Selecting more sensitive reagents and more sensitive method for the amplification of virus nucleic acid can shorten the infection risk of the window period as far as possible for ensuring the safety of blood transfusion .

Objective To improve the recognization of hip joint lesion in ankylosing spondylitis and it's related factors.Methods Pelvis computed radiography(CR) and HLA-B27 were examined in 100 cases of ankylosing spondylitis proved by clinical.Results 58% cases appeared differed degree of narrowing of the interticular space,osteoporosis on head of femur and acctabulum,cystis under the surface of acctabulum and joint inosculated.This probability was higner at thoe patients that had diaease at youthful or HLA-B27(+).Conclusion Hip joint lesions of ankylosing spondylitis appear characteristic signs in CR.It relates with the age that the disease come on and HLA-B27.

[Objective] To observe the cure effect of photodynamic therapy(PDT) combined with TCM on verruca acuminata. [Method] Select 80 cases of verruca acuminata, divide them into control group and treatment group, n=40 for each; the control one only took LE D-IB PDT therapeutic apparatus, the treatment one added with TCM on the base of control one; Observe their cure effects and side effects. [Result] The effective rate was 97.5% for treatment group, and 88.5% for control one, the treatment one was better than other one; there ’re 2 cases in each group respectively who had slight red and swol en skin of the il umination part, without side effects of erosion, ulcer, infection or scar;the recurrence rates were respectively 2.5% and 12.5% for both groups, the difference had statistical meaning. [Conclusion] PDT combined with TCM treating verruca acuminata had high cure rate, low recurrence rate, little side effects and high safety, without influencing patients ’life quality, with good compliance, worth clinical broad popularization.

Objective To explore the clinical value of oral ultrasonic contrast agent ultrasonography (OUCAUS) combined with serum monocyte chemoattractant protein-1 (MCP-1) and cell adhesion molecule-1 (CAM-1) measurement in preoperative staging of stomach carcinoma.Methods 800 gastric cancer patients were diagnosed by electric gastroscopy and OUCAUS.The preoperative staging was measured by OUCAUS and compared with pathologic staging,and serum levels of MCP-1 and CAM-1 were measured with ELISA.Results The total accuracy rate of OUCAUS was 79.9％ in estimating invasive depth of stomach neoplasm,82.9％ in estimating lymphatic metastasis and 88.6％ in estimating distant metastasis respectively.The expression levels of MCP-1 and CAM-1 in serum were closely correlated with invasive degree,lymphatic metastasis,distant metastasis and pathologic staging (all P ＜ 0.05).The total accuracy rate of combining OUCAUS and MCP-1,CAM-1 was 93.0 ％ in estimating invasive depth,93.9％ in estimating lymphatic metastasis and 98.6％ in estimating distant metastasis respectively.The total accuracy rate of combining OUCAUS and MCP-1,CAM-1 in estimating invasive depth,lymphatic metastasis and distant metastasis was significantly higher than that of by OUCAUS alone.Conclusions MCP-1 and CAM-1 serum levels are closely correlated to pathologic staging of gastric cancer.Combining OUCAUS and MCP-1,CAM-1 can increase the accuracy rate determining invasion and metastasis in gastric cancer.

Objective To detect the plasma plasminogen activator inhibitor-1(PAI-1)and urokinase-type plasminogen activator(uPA)levels in PCOS and control of different BMI.Methods This experiment is divided into PCOS group and control group,PCOS group also divided into obesity and without obesity.To assay plasma PAI-1 and serum uPA of PCOS with or without obesity by enzyme-linked immunosurbent assay(ELISA),and to meassure body mass index(BMI),waist hip ratio(WHR),blood glucose,fasting insulin and IRT.To evaluate insulin resistance with Homa Model and to measure insulin area under curve(AUC).Results LH/FSH,T,blood glucose,HOMA-IR,AUC and the plasma level of PAI-1 were significantly increased in PCOS as compared with normal control,and HOMA-IR,AUC and the plasma level of PAI-1 were also increased in obesity as compared with non-obesity of PCOS(P
