Objective: To investigate the awareness of hepatitis C prevention and control knowledge and its influencing factors among female sex workers (FSWs) in Jiaxing City, Zhejiang Province. Methods: According to the HIV/AIDS Sentinel Surveillance Plan, FSWs at ages of 15 to 65 years monitored by the national AIDS surveillance sentinel in Jiaxing City were recruited, and demographic information, awareness of hepatitis C prevention and control knowledge and related behaviors were collected by questionnaire surveys. Factors affecting the awareness of hepatitis C prevention and control knowledge were identified by a multivariable logistic regression model. Results: A total of 430 questionnaires were allocated, and 412 were valid, with an effective rate of 95.81%. The respondents had a mean age of (28.58±4.93) years, and included 258 unmarried FSWs (62.62%), 344 with registered residence outside Zhejiang Province (83.50%), 212 with junior high school education or below (51.46%) and 243 from high-end entertainment places (58.98%). The overall awareness of hepatitis C prevention and control knowledge among FSWs was 20.39%, and the awareness of "Transfusion of blood containing hepatitis C virus may acquire hepatitis C" (38.83%) and the awareness of "tattooing, eyebrow tattooing and ear piercing in streets or small shops may infect hepatitis C" (38.11%) were relatively low. Multivariable logistic regression analysis identified marital status (divorced or widowed, OR=0.161, 95%CI: 0.054-0.482), educational level (high school or technical secondary school, OR=2.568, 95%CI: 1.446-4.560; junior college or above, OR=6.110, 95%CI: 2.658 -14.045) and grade of entertainment places (high-end entertainment places, OR=2.756, 95%CI: 1.525-4.982) as factors affecting the awareness of hepatitis C prevention and control knowledge among FSWs. Conclusion FSWs in Jiaxing City have a low awareness of hepatitis C prevention and control knowledge, especially lacking of knowledge about the transmission routes and prognosis of hepatitis C.

Objective To establish and assess the utility of 99Tcm-sulfur colloid (SC) salivary imaging in the routine evaluation of pulmonary aspiration in adult patients with respiratory tract diseases.Methods Eight patients (7 men,1 woman; age range 68 to 80 years,mean age (76 ± 4) years) with respiratory tract disease and history of aspiration by clinical assessment were evaluated prospectively by 99Tcm-SC salivary imaging from April to July 2012.A dose of 74.0 MBq 99Tcm-SC was added to 20 ml saline,mixed well,and administered orally to patients.Dynamic imaging was acquired with posterior projection for 30 min at a rate of 30 s per frame.Two experienced physicians assessed all examination results and reached consensus for final diagnosis.Radioactivity detected at either the bronchi or within the lung fields was reported as positive for aspiration.This study was approved by the institutional review board of Hospital Ethical Committee,and the written informed consent was obtained from patients or their guardians.Results All patients were positive for aspiration by 99Tcm-SC salivary imaging (8/8).Aspiration into bilateral main bronchus was seen in 2 cases,right main bronchus and branch in 4 cases,and left main bronchus and branch in 2 cases.Aspirated tracer could be visualized as early as 3 min,latest at 24 min,and the median was 19 min.Conclusion 99Tcm-SC salivary imaging is useful for the detection of aspiration in adult patients with respiratory tract diseases.

Objective To observe the resection of the scapholunate interosseous ligament (SLIL)and its subregions on the three-dimensional(3-D)movement of the scaphoid and lunate so as to discuss the role of SLIL in the 3D flexion-extension motion of the scaphoid and lunate.Methods Twelve upper extremities(six left extremities and six right extremities)from adult cadaver were used in this study and divided into five groups:normal group,proximal subregion resection group,proximal subregion plus dorsal subregion resection group,proximal subregion plus palmar subregion resection group and whole SLIL resection group.The 3-D laser scan and reconstruction technique were used for meusure ment of the 3-D flexion-extension motion of the scaphoid and lunate.Results In the normal group,the scaphoid and lunate flexed and the radial deviated at the same direction during wrist flexion-extension motion.At the same time,there was minimal scaphoid and lunate pronation-supination during wrist flexionextension.After resection of the proximal and palmar(or dorsal)subregions of the SLIL,some different movements were found compared with the normal specimen.Whole SLIL resection resulted in increase of the flexion motion of the scaphoid but decrease of the palmar flexion of the lunate.Conclusions 3-D laser scanning and image reconstruction techniques can accurately measure the 3D motion of the scaphoid and lunate.Partial or whole resection of SLIL may exert significant effect on the flexion-extension motion of the scaphoid and lunate.However,the proximal subregion of SLIL has no prominent effect on the motion of the scaphoid and lunate.

Objective To explore small size toe tissue flap for aesthetic reconstruction of the thumb and / or finger. Methods Six kinds of small size toe tissue transplants had been applied in repairing skin-bone-joint composite tissue defects of the thumb or finger in 74 cases. Results Among 83reconstructed flaps of the 74 patients, 81 flaps survived completely. Follow-up examination made three to forty-eight months postoperatively showed that the outward appearance were excellent in most cases. The function of the thumbs or fingers were good. The donor feet can walk normally with no pain. Conclusion A variable combinations of toe tissues including skin, soft tissue, bone and joint can be harvested to form a lot of small size transplants for refined aesthetic reconstruction of thumb and finger. The functional and aesthetic results are good and the treatment course is shortened.

Purpose To investigate the expression of programmed death ligand-1 (PD-L1) in breast cancer tumor cells and stromal tumor-infiltrating lymphocyte (sTIL),and to study the relationship between the expression of PD-L1 and the clinicopathological characteristics of the patients.Method The protein expression of PD-L1 was detected by immunohistochemistry of EliVision two-step method in 68 cases of non special type of invasive breast cancer,and the relationship between the expression of PD-L1 protein and the immunohistochemistry subtypes and clinical parameters was analyzed.Results The total expression rate of PD-L1 was 35.3％ in breast tumor tissue,specially in triple negative breast cancer (TNBC) which occupy the highest positive rate.The expression rates of PD-L1 in tumor tissue of the luminal subtype,HER-2 over-expression subtype and TNBC subtype were 16.1％,37.5％ and 61.9％ respectively,and the difference was statistically significant.The total expression rate of PD-L1 in sTIL was 51.5％,and the highest expression rate was 81.0％ in TNBC.There were significant differences of PD-L1 expression in sTIL of the luminal subtype,HER-2 over-expression subtype and TNBC subtype.Expression of PD-L1 in tumor tissue and sTIL had a significant positive correlation.Conclusion PD-L1 expressed in TNBC was significantly higher than other types of breast cancer,which suggest the blocking of signal pathway of PD-1/PD-L1 may expected to become a new immunotherapy for breast cancer,especially for TNBC subtype.
