Objective To investigate the clinical value of bone scintigraphy for the diagnosis of synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome. Methods The characteristics of SAPHO syndrome on 99Tcm-MDP imaging of 8 cases were retrospectively analyzed. Results The 99TcmMDP bone scan was positive for all patients. Seven cases were found lesions in the costoclavicular region, 3cases involved with unilateral sacroiliac joint, 2 cases involved with spine and 1 patient with extremity. Four lesions were found without relevant clinical symptoms. Conclusion Bone scintigraphy is useful for the diagnosis of SAPHO syndrome, especially for those lesions with no clinical symptoms.

Objective To investigate the prevalence of clonorchiasis among residents of Huachuan Country,Heilongjiang Province and to provide a basis for development of control strategies.Methods From 2011 to 2012,cluster random sampling was performed to survey the incidence of clonorchiasis in Huachuan Country.Fecal specimens were collected and examined the clonorchis sinensis eggs by Kato-Katz method.A questionnaire survey was conducted to collect related information such as age,gender,occupation and eating habits.The infection characteristic was analyzed.Results Totally 884 patients with clonorchiasis were found among 2248 residents,and the infection rate was 39.32％.The infection rate in male[47.15％(611/1296)] was significantly higher than females [28.68％(273/952),x2 =34.55,P ＜ 0.01].The infection rate increased with age,which was higher in the 20-69 years old people,with the highest infection rate in the 50-59 years old groups[45.34％ (219/483)].Of the occupational distribution,farmers had the highest infection rate [47.24％ (420/889)],followed by cadres and staffs[38.38％(190/495)].Of residents with fresh fish eating history,the prevalence of clonorchiasis was 53.38％(150/281).Conclusions The prevalence of clonorchiasis is still high in Huachuan County.To reduce the prevalence of clonorchiasis,comprehensive prevention measures,health education and group chemotherapy should be carried out.

Objective To investigate the clinical value of 99Tcm-MIBI gated G-MPI in detecting the myocardial damage in sarcoglycanopathy.Methods 99 Tcm - MIBI G - MPI was performed in 8 patients (3 males,5 females,age ranged from 10 to 30 y) with sarcoglycanopathy confirmed by clinical results and molecular pathology and 4 healthy persons as control group.Quantitative gated SPECT (QGS) software was used for processing and interpretation.Myocardium of left ventricle was divided into 7 segments and 20 subsegments.A five-point scoring system was used to evaluate the myocardial damage.Results Seven patients showed positive results in G-MPI (7/8).Fifty-nine sub-segments of injured myocardium were detected in the 140 sub-segments of 7 abnormal patients.One abnormal segment was observed in 1 patient,two abnormal segments were detected in 2 patients,and ≥3 abnormal segments were observed in 4 patients.Enlarged left ventricles were detected in 5 patients (5/8),and the LVEF of 3 patients among them decreased to (43.1 ±2.8)％.Conclusion 99Tcm-MIBI G-MPI can detect myocardial damage in sarcoglycanopathy as a direct and non-invasive method,and can be used in the early diagnosis and long-term follow-up in sarcoglycanopathy.

Objective To explore the heterosexual intercourse characteristics and its influencing factors among MSM population. Methods Voluntary counseling/testing and questionnaire survey were carried out at the bathhouses where MSM usually assemble. Results Among 342 MSM surveyed,52. 05% were married. 76 people( 22. 22%) were completely homosexual,while 266 people(77. 78%)were bisexual. 24(31. 57%)MSM who answered″ totally gay″ in self-assessment of sex orientation were married,significantly lower than those answered bisexual(57. 89%)(p<0. 05). 197 of participants had sex with women ,and 123 MSM had sex with women during the last six months,49 MSM of which used condoms at each heterosexual activity. MSM who were married or bisexual were easy to have heterosexual intercourse. Among the MSM surveyed,the HIV and syphilis infection rates were 11. 40% and 16. 67% respectively. There was no significant difference between the use of condoms and infection( both p>0. 05). In the recent six months,there was no significant difference in the use of condoms between infected( 43. 34%)and non-infected persons( 43. 34%)( p >0. 05). Conclusion Among MSM population,the prevalence of heterosexual intercourse is high,while condom use rate is relatively low. It is necessary to strengthen the behavioral intervention and promote condom use.
