Objective To investigate the usefulness of 99Tcm-MDP whole body bone scintigraphy (WBBS) in patients with synovitis,acne,pustulosis,hyperostosis,osteitis (SAPHO) syndrome.Methods 99Tcm- MDP WBBS was performed in 25 patients (6 males,19 females,mean age =(55.1 ±9.8) years)with SAPHO syndrome.Bone lesions were classified into five categories:anterior chest wall,spine,mandible,sacroiliac joint,and limbs.The typical scintigraphic manifestations of SAPHO syndrome were summarized and compared to other radiological imaging data.Results Among 25 patients,32％ of cases (8/25)were associated with skin lesion; 48％ ( 12/25 ) were pathologically diagnosed with chronic nonspecific bone inflammation by bone biopsy.On 99Tcm-MDP WBBS,abnormal metabolic foci at anterior chest wall were found in all cases,most of which located in the sternocostoclavicular region (96％,24/25 ),including sternoclavicular joints (60％,15/25),first costosternal junctions (48％,12/25),and manubriosternal junctions (44％,11/25 ).Only 20％ of the patients (5/25) demonstrated the typical scintigraphic characteristic:“bull's head” sign.The second most frequent part was spine (44％,11/25).Appendicular skeleton was affected in 16％ (4/25) patients.WBBS also demonstrated additional skeletal lesions in 68％ (17/25 ) of the patients,mainly in first costosternal junctions (7 patients),sternoclavicular joints (6 patients),manubriosternal junctions (5 patients) and spine (4 patients).Conclusions Abnormal metabolic foci in sternocostoclavicular region and other imaging manifestations on 99Tcm- MDP WBBS can be used to diagnose,differentiate,and localize the insidious lesion and evaluate the lesion activity in patients with SAPHO syndrome.

Objective To evaluating the effectiveness of comprehensive measures to control the plague in epidemic areas in Longlin county Guangxi from 2001 to 2010.Methods Original epidemic places was deratised,indicative animals were investigated,and epidemic clues were searched.Cage trapping method was used to capture rat and rat body fleas were collected in the plague epidemic areas.The flea-carrying rates and flea index of rodents were calculated based on the number of fleas collected from caged rodents.The animals were then subjected to etiological and serological tests to determine the plague infection rate.Results A total of 1008 rats were captured and 571 fleas were collected from 2001 to 2010,of which Rattus Flavipestus accounted tor 81.65％(823/1008) and Xenopsylla Cheopis for 64.10％(366/571).The annual average rodents infected with flea and the index of flea were 23.02％ (177/769) and 0.74,respectively.The annual average density of rodents decreased from 3.99％ (859/21 508,before deratised) to 0.96％ (149/15 600,after deratised).The deratization rate was 75.94％.Conclusion The risk of a plague epidemic in Longlin county is reduced after continued comprehensive measures be taken to deal with the disease.

Objective To summarize the ultrasonographic features and differential diagnosis of uterine cornual pregnancy.Methods Trans-abdominal and trans-vaginal ultrasound were performed in 93 uterine cornual pregnancy patients before surgery,ultrasonographic findings of uterine cornual pregnancy through different two approaches were analyzed and compared with surgical and pathologic findings.ResultsIn contrast with surgical and pathological diagnosis,66 cases(82.5%,66/80) of uterine cornual pregnancy were accurately diagnosed by ultrasonography before surgery,these cases were divided into gestational sac pattern (55 cases) and mixed mass pattern(11 cases); 11 cases were misdiagnosed as interstitial tubal pregnancy,2 cases were misdiagnosed as pregnancy in rudimentary horn,1 case was misdiagnosed as choriocarcinoma,misdiagnosed rate were 17.5%(14/80); uterine cornual pregnancy presented as adnexal mass in ultrasound in 13 cases,while ruptured uterine cornual mass were found in surgery,in which location and type of the masses couldn't be accurately diagnosed by ultrasound.Ultrasonographic features of uterine cornual pregnancy presented as a gestational sac located in extended cornual of uterus,surrounded by thin myometrium,and connected with endometrium.The misdiagnosed causes were: (1) Uterine cornual mass was not connected with endometrium or surrounded by thin myometrium,which were misdiagnosed as interstitial tubal pregnancy.(2) Uterine cornual pregnancy with thick lateral myometrium were misdiagnosed as pregnancy in rudimentary horn.(3)Uterine cornual pregnancy presented as cornual mass with abundant blood flow was misdiagnosed as choriocarcinoma.Conclusions Uterine cornual pregnancy can be accurately diagnosed by trans-abdominal and trans-vaginal ultrasound.Ultrasonographic features are helpful in differential diagnosis of uterine cornual pregnancy.

Objective To analyze the outcome of surveillance results on plague and to provide the evidences for the policy making in Longlin county Guangxi. Methods The epidemic data and the surveillance results of plague were analyzed and assessed with epidemiology methods in Longlin county Guangxi from 2000 to 2009, and the density of rodents, the rodents infected with flea, flea index and other indicators were calculated. Regional composition of the rats and fleas were analyzed. Results A totally of 4829 rats were captured and 4737 fleas were collected in the past 10 years, Rattus Flavipestus(81.92%,3956/4829) and Xenopsylla Cheopis (79.04%,3744/4737) were dominant species. The annual average density of rodents, the rodents infected with flea, index of flea were 3.30%(4829/146 206), 27.99%(1351/4827) and 0.98(4737/4827), respectively. A totally of 4792 rats were examined and 10 strains Yersinia Pestis were isolated. Indirect hemorrhagic assessed(IHA) was used to test the F1 antibody against plague in the blood serum of the rats and indicator animals, and 3 positive rats and 24 positive animals were found, respectively. Twenty seven natural villages in 3 towns had been involved in the plague. Conclusions The plague foci exists in Longlin county of Guangxi province. The plague foci in the areas have the same feature with the plague foci of Rattus Flavipectus. There is a potential risk for plague in this region, we should improve the quality of surveillance, increase indicator animals of the plague, and try to apply new surveillance method.

OBJECTIVETo explore the effects of lead on the thyroid function of occupationally exposed workers.

METHOD157 workers occupationally exposed to lead in a smelting factory were investigated. The concentration of lead in air at workshop was measured by flame atomic absorption spectrophotometry (FAAS) and the levels of blood lead (PbB) by atomic absorption spectrophotometry (AAS), zinc protoporphyrin (ZPP) by ZnPP meter, as well as the indexes of thyroid function, thyroid-stimulating hormone (TSH), triiodothyronine (T(3)), thyroxin (T(4)), free T(3) (FT(3)), and free T(4) (FT(4)) in serum by radioimmunoassay.

RESULTSThe workers with higher level of blood lead (> 2.88 micro mol/L) showed lower levels of T(3) [(1.54 +/- 0.39) nmol/L] and FT(3) [(5.50 +/- 1.26) pmol/L] than those with lower blood lead level [PbB: (1.92 approximately 2.88) micro mol/L group, T(3): (1.71 +/- 0.45) nmol/L, FT(3): (6.12 +/- 1.64) pmol/L, P < 0.05]. There was no obvious effect of length of service on thyroid hormone of exposed workers.

CONCLUSIONHigher level of blood lead may cause certain damage to thyroid function by inhibiting deiodination of T(4). No obvious relation between length of service and thyroid function was found.

Serum samples from endometrial cancer (EC) patients and healthy females were analyzed using surface-enhanced laser desorption-ionization time-of-flight mass spectrometry (SELDI-TOF-MS) to discover the potential diagnostic biomarker for detection of EC. A preliminary training set of spectra derived from 40 EC patients and 30 healthy women were used to develop a proteomic model that effectively discriminated cancer patients from healthy women. The training set had a specificity of 100% and sensitivity of 92.5% in the EC detection. A blind test set, including 20 new cancer cases and 10 healthy women, was used to validate the sensitivity and specificity of this multivariate model, which had a corresponding results of 60% in specificity and 75% in sensitivity, respectively. The combination of SELDI-TOF-MS with bioinformatics tools could help find new biomarkers and establish the detection of EC with high sensitivity and specificity.
