Objective To investigate knowledge and attitudes of healthcare workers with respect to HIV/AIDS in Fugong County,Nujiang District and to highlight the difficulties facing local healthcare workers in HIV/AIDS health education in order to help them improve their skills and capability of health education through participatory learning.(note:the major inhabitants in NuJiang are the Lisu ethnic).Methods A survey with questionnaires was carried out before starting a HIV/AIDS health education training course for healthcare workers in Fugong County.Then an interactive and participative HIV/AIDS training was provided for these healthcare workers.A post-training survey was followed.Results Before the training course,the score of HIV/AIDS related knowledge was 56.71 on average.The average score increased to 83.93 after the participatory HIV/AIDS health education,(by SPSS analysis).Such an increase was obviously associated with their participation in the training course.The knowledge the participants learned during the training course was effectively used for conducting health education among local inhabitants.Conclusion We found that a participatory/interactive HIV health education training course is useful in raising the awareness and understanding of HIV/AIDS among healthcare workers in areas such as Fugong.We encourage more efforts to hold such courses in order to prevent the spread of HIV/AIDS.

Laryngopharyngeal reflux (LPR) is gaining extensive attention in recent years because of the high incidence. But because of the complex symptoms and signs, there exist no diagnostic consensus. In this paper, the available objective diagnostic methods so far are reviewed, in the purpose of discussing the approach of objective and accurate diagnosis of LPR.

Objective: To compare the difference of Vitamin B in serum in healthy adults and patiens with Crohn's disease.Methods: 24 healthy adults and 20 patients were measured for Vitamin B1,B6,B12 in serum.A HPLC-DAD method was developed to determine vitamin B extracted directly from human serum.Purospher RP-18 column was used for the gradient elution with mobile phase: 0.04 mol phosphate buffer: methanol(60∶40).Results: The results proved to be linear in measurements of VB1,VB6 and VB12 and the correlation coefficients were 0.999 827,0.985 097 and 0.999 994,respectively.The contents of Vitamin B(VB1,VB6,VB12) in Cronhn's patients were significantly lower than in healthy adults.Conclusion: The measurements of Vitamin B in human serum by HPLC-DAD method are clinically helpful to diagnosis and treatment for Crohn's disease.

To study the effects of the material of a buildup cap to the determined value of Output FactorSc．Material and MethodsUsing two buildup caps made of plastic A－150 and copper respectively．The ionizing values of ionization chamber were measured with Farmer 2570 electrometer in the fields of all kinds of sizes respectively and calibrated to reference field．Two groups of values of Sc were obtained and compared． Results The ionizing values measured with the buildup cap of copper is evidently larger than with the buildup cap of plastic A－150 and the maximum is 14％ but the difference between two groups of the values of Sc is not much evident and all is in the range of 1％． Conclusions Though the material of high density is not equivalent with airthe effects of that to the measured value of Sc is less．So using the buildup cap made of the material of high density for the measurement of Sc is also a quite good method specially in the fields of the small sizes．

Objective To investigate the relationship between the type of gliding contusion and its mechanism with site of force.Methods The site undergoing contusion and ways of force are respectively determined by skull anatomy location and details of these cases.Then,the 132 specimens of brain,which have been fixed by formalin,are sliced in coronal section and sagittal section and stained with HE,observed under microscope.ResultsGliding brain contusion could appeared at the top and bottom region of brain respectively.Top-injury type,were observed in 65 cases(49.24%),base-injury type,were found in 38 cases(28.78%).There were 29 cases(21.96%) in which contusion could be found at both top and base of brain,we called mixed type.We found that the injury area depend on the ways of force-act:the top-injury type mostly caused by the force on cupular part of pars zygomatica in acceleration,the base-injury type mainly caused by the force on occipitalia in deceleration and the mixed type caused by the force on the boundry of the calvaria and occipital in deceleration.Conclusion The type of gliding contusion is relevant with mechanism and site of force.

Objective To investigate factors influencing the quality of life (QOL) of cancer patients with bone metastases. Methods Eighty-two cancer patients with hone metastasis were investigated.A questionnaire designed according to European Organization for Treatment of Cancer quality of life questionnaire ( EORTC QLQ-C30),Monroe Dunaway Anderson symptom inventory-Chinese edition (MADSI-C) and hospital anxiety and depression scale (HADS) standards was used to collect the information. Results The average total standardized QOL score of these cancer patients was 53.28±19.20.Among the function subscales,social function got the lowest average score (47.54),while among the symptom subscales fatigue got the highest average score (56.65).According to the MDASI-C,the most serious symptom burdens were fatigue,distress and pain; working and walking experienced the most interference.The symptom burdens correlated significantly with the QOL results.Twenty-four of the patients (29.3％) had been diagnosed with anxiety,and 17 (20.7％) were diagnosed with depression.Anxiety and depression continued to be significantly associated with overall QOL and its various dimensions. Conclusions The results　show that the burden of fatigue and pain,as well as of anxiety and depression are significantly associated with impaired QOL among cancer patients with bone metastasis.Work (housework) and walking were the most severely affected activities.Psychological rehabilitation should be focused on the comprehensive treatment of patients with bone　metastasis along with other appropriate rehabilitation strategies to enhance their overall functioning,relieve their　symptoms and improve their QOL.

OBJECTIVE　To develop an asssay for the quantitative determination of phillyrin in Shuanghuanglian tablet.METHODS　TLCS method was selected to determine the content.RESULTS　The linearity was obtained over the range of 0.31～ 1.55 μg(r=0.9996).The average recovery was 96.9% with RSD=1.49%.CONCLUSION　The results showed that this method is sensitive,simple,specific and accurate for the determination of tetrahydropalmatine in Shuang Huanglian tablet.

Protease activated receptor-2(PAR-2)is a G-protein-coupled receptor.Recent studies indicate that PAR-2 is mainly expressed in leukocytes and activated by pancreatin and(or)tryptase,which subsequently induces inflammation through degranulation of leukocytes.Activation of PAR-2 in leukocytes is possibly involved in the pathogenesis of rheumatoid arthritis.

[ABSTRACT]OBJECTIVETo diagnose laryngopharyngeal reflux (LPR) by using two methods: 24h pH monitoring and RSI combined with RFS scales. To research the voice characteristics of patients with LPR and changes of voice parameters before and after PPIs therapy, and to use voice parameters to help diagnosing and evaluating treatment effect of LPR.METHODSThe patients visited department of Otolaryngology head & neck surgery of Peking University Third Hospital from August 2012 to August 2013 were included in this study. There were 26 LPR patients diagnosed by 24 hr pH-MII monitoring (pH group) and 26 LPR patients diagnosed by RSI combined with RFS (questionnaire group). Another 52 subjects without laryngeal or pharyngeal symptoms were as control group. All subjects underwent MDVP examination. The patients from pH group and questionnaire group took esomeprazole 20 mg bid for one month, afterwards MDVP was examined again. The voice related parameters were compared before and after medication therapy.RESULTSComparing data between LPR patients and normal subjects, Jitter, Shimmer, NHR had significant difference (P<0.05), and F0, MPT had no significant difference (P>0.05) before treatment. After PPIs therapy there was no significant difference between each group (P>0.05).CONCLUSIONAbnormal voice parameters were existed in LPR patients. After PPIs treatment, voice related parameters improved apparently.
