ABSTRACT
Objective@#Despite the remarkable progress in efforts to control disease spread, the nationwide elimination of hepatitis B in China is still hindered by the persistently high rate of hepatitis B virus (HBV) infection in Western China. This study aimed to evaluate the strategy of hepatitis B prevention and control in Western China and identify potential areas and strategies for improvement.@*Methods@#Susceptible population vaccination, health education, professional training of doctors, and other prevention and control measures have been implemented in Wuwei city since 2010. Data were obtained from three representative cross-sectional serosurveys conducted in 2010, 2013, and 2015. The serum samples were subjected to enzyme-linked immunosorbent assays to detect the following seromarkers: HBV surface antigen (HBsAg), antibody against hepatitis B surface antigen (anti-HBs), and antibody against hepatitis B core antigen (anti-HBc). Estimates of variance were determined using Taylor series linearization methods.@*Results@#The three serosurveys revealed decreases in the prevalence of HBsAg (7.19% in 2010 @*Conclusion@#Although vaccine-based prevention and control measures reduced the rate of HBV infection in Wuwei City over time, the hepatitis B infection rate in children younger than 10 years was still higher than the national average level. Therefore, the prevention and control of mother-to-child transmission and the management of the infected should be the focus of future prevention and control work.

<p><b>OBJECTIVE</b>To evaluate the quality of life and influencing factors on patients with multiple myeloma (MM).</p><p><b>METHODS</b>227 MM cases were selected at 5 hospitals in Xi'an from August, 2010 to March, 2013. QLQ-C30 was used to evaluate the quality of life of MM patients, and their norms were as control. Factors which influencing the quality of life were investigated and analyzed with SPSS 17.0 software.</p><p><b>RESULTS</b>The total score of quality of life in MM patients was 49.0±21.7 which was lower than the norms (60.7±23.4). The scores on fatigue, nausea, vomiting, pain, short of breath, disturbance on sleeping, losing appetite, constipation, other symptoms and financial difficulty were significantly higher than data of the norms (P < 0.05). Factors as being elderly (especially those older than 70), under higher proportion of medical costs on their own expense or financial difficulty etc., had major influences on the quality of life (P < 0.05) of MM patients who in particular having worse quality of life when in worsening clinical ISS stage (P < 0.05). Low level of hemoglobin, high level of serum calcium and globulin all significantly reduced the quality of life of the MM patients (P < 0.05).</p><p><b>CONCLUSION</b>The quality of life of MM patients was significantly lower than the normal people or patients with other tumors. Fatigue, pain, and financial difficulty were main influencing factors on the quality of life of MM patients. The assessment on the effects of treatment should relate to the improvement of hemoglobin, serum calcium and globulin, which could all improve the quality of life of MM patients.</p>
