Objective To investigate the effect of surgical treatment combined with 131I in the treatment of thyroid papillary carcinoma.Methods45 cases of papillary thyroid cancer patients were selected from January 2008 to January 2012 in our hospital.All of the patients were treated with total thyroidectomy surgical,postoperative underwent thyroid hormone and 131I radionuclide therapy,The patients were followed up.ResultsAt 3 months or 6 months after operation,the levels of serum P53,Fas and TNF-a were significantly higher than immediate time after surgery (P<0.05) and cyclin E protein levels were significantly lower than immediate time after surgery (P<0.05).There were no difference of serum P53,Fas,TNF-and Cyclin E protein levels between at 3 months and 6 months after operation.During five years of follow-up, the 5-year recurrence rate of 4.4%,and the distant metastasis rate was 2.2%.ConclusionOperation combined with 131I radionuclide therapy has good clinical results,could be used as the first choice for clinical treatment.

Objective The present study was designed to investigate the efficiency of simvastatin therapy for experimental pul‐monary hypertension (PH) in rat ,and the effects on the number and function of circulating endothelial progenitor cells (EPC) . Methods Twenty four Sprague Dawley rats were divided into 3 groups randomly :model group ,treatment group and control group , 8 rats in each group .Rats were treated with a single subcutaneous injection of monocrotaline to induce PH (PBS used as control) . The rats in the experimental group were administrated with simvastatin 3 days following subcutaneous injection of monocrotaline .In the 21st day ,the number of circulating EPC ,the right ventricle systolic pressure of rat ,pulmonary vascular structural changes and the quantity of cultured EPC were measured .At the same time ,EPC in each group were cultured in vitro ,then the ability of prolif‐eration and function were analyzed and compared .Results The number of circulating EPC in model group was decreased signifi‐cantly compared to both control and model groups (P< 0 .01) .Compared with model group ,simvastatin treatment markedly de‐creased the RVSP and the ratio of media thickness to eternal diameter (P<0 .01) ,but the ratio of vessel area to total arterial area (VA/TAA) was definitively increased(P<0 .01) .After 7 days of culture in vitro ,both the output of EPC and the ability of prolif‐eration ,conglutination and migration of EPC in treatment group were up -regulated compared with those in model group (P<0 .01) .Conclusion This study confirmed that simvastatin effectively treat experimental PH through improving quantity and func‐tion of circulating EPC .

7.Sociocultural Factors Associated with Caregiver-Psychiatrist Relationship in Taiwan.
Psychiatry Investigation 2016;13(3):288-296
OBJECTIVE: Research on sociocultural factors associated caregiver-provider relationship is needed to enhance family involvement in psychiatric care. This study examines from the caregiver's perspective the associations of schizophrenia attributions, stigmatization, and caregiving experiences with caregiver-psychiatrist working relationship in Taiwan. METHODS: This cross-sectional study used a convenience sample of 152 Taiwanese family caregivers of persons diagnosed with schizophrenia, recruited from a grassroots organization, 4 community mental health rehabilitation centers and 2 psychiatric hospitals between July 2012 and March 2013. Multiple linear regression models were used for analysis. RESULTS: Biological attribution was positively associated with perceived family collaboration, and so was environmental attribution with perceived informational support. Internalized stigma was negatively associated with perceived family collaboration. Caregiving rewards were positively related to both perceived family collaboration and informational support, and so was experience of problems with services to perceived family collaboration. CONCLUSION: The examination of family perceptions informs Western psychiatric care providers of the importance of culturally sensitive practices in developing an effective working relationship with family caregivers, particularly in regards to caregivers' casual attributions, impact of stigma, and caregiving experiences.

Objective To observe the effects of electro-acupuncture ( EA ) on learning, memory and the morphology of hippocampal neural tissues in rats with a model of chronic cerebral ischemia.Methods One hundred and twenty male Sprague-Dawley rats were used. Chronic cerebral ischemia models were successfully established in 104 of them, and those rats were randomly divided into an EA group and a model group with 52 rats each. These were further subdivided into 1,2, 4 and 6 week subgroups with 13 rats in each. The EA group was given EA. The changes in spatial learning and memory ability were observed using a Morris water maze. The morphological changes in hippocampal nerve tissue were observed by HE staining.Results The escape latency in the EA group was significantly different from the model group at the 2nd, 4th and 6th week. The nerve cells in the dentate gyrus were more tightly and consistently lined-up and had rich layers, and the structures in the EA group were better than in the model group.Conclusions EA can improve spatial learning and memory and promote the repair of injury after cerebral ischemia.

Objective To discuss the value of moving darkroom and accompanying X-rays protective shield in endemic fluorosis areas.Methods Using moving and fixed darkrooms,the X-rays photos of the forearms and shanks of the 320 persons were developed in the endemic fluorosis areas,while the time for development and installing-uninstalling films was documented.The films develpoed in the darkroom were evaluated for the quality.Results Among the 320 films develpoed in the moving darkroom,the 268 had fingerprints,47 had scratches,298 were in good quality(93.13%),while in the fixed darkroom,the figure was correspondingly 735,384,227(70.93%);The moving darkroom increased excellent film rate significantly than fixed darkroom(χ2=53.43,P<0.01),The detectable rate of skelelal fluorosis and degree Ⅰ skelelal fluorosis were highter than that in the fixed darkroom did (χ2=10.34,χ2=9.56,P<0.01).Conclusions The films developed in moving darkroom have superior quality and higher diagnostic value,so it is important to use moving X-rays photographing in ecdemic fluorosis areas.

Objective To investigate the effects of in vivo electroporation on plasmid mediated reporter gene expression and immunogenicity of DNA vaccine. Methods Luciferase expression plasmid was administered intramuscularly to BALB/c mice at 8μg and 40μg dosage level through injection with or without eletroporation Luciferase expression level in murine muscle was detected by IVIS imaging system 24 h after injection. DNA vaccine plasmid p1.0-gp1455m carrying codon-optimized env gene of CN54 strain ( HIV-1 CRF07_BC) was administered to mice at dosages of 8μg and 40μg through the two approaches mentioned above. Mice were immunized at week 0,2 and 4. Env-specific immune responses were detected at two weeks post the second and the third vaccinations. Env-specific antibody immune responses were determined by ELISA. Euv-specific cellular immune responses were determined by IFN-γ ELISPOT. Results Luciferase expression level in murine muscle was significantly increased as much as 35 folds through in vivo eletroporation. Results of ELISA and ELISPOT revealed that in vivo eletroporation could significantly enhance both the humoral and cellular immune responses induced by DNA vaccination. The responses induced by electrodelivered p1.0-gp1455m at 8 μg dosage were better than those induced by simple intramuscular injection with 40 μg of plasmid DNA. On the other hand, 2 injections followed by electroporation elicited comparable level of humoral and cellular immune responses with those induced by 3 injections without electroporation. Conclusion In vivo electroporation was capable of enhancing both the plasmid-mediated gene expression and immunogenicity of DNA vaccine.
