pylori detection. Results The prevalence of H. pylori infection was 46.5% (507/1090). The infection rate in men was 51.8%, which was significantly higher than that in women (42.5%; P less then 0.05). The H. pylori infection rate in illiterate people was significantly higher than that in literate persons (53.5% vs 44.8%, P less then 0.05). The total infection rate of H. pylori gradually increased with age and the difference was statistically significant (P less then 0.01). The H. pylori infection rate in smokers was significantly higher than that in non-smokers and those who had quit smoking (P less then 0.05). Conclusion The prevalence of H. pylori infection among elderly people is 46.5% and the infection rate gradually increases with age. Sex, education level, age, and smoking were determined to be H. pylori infection risk factors. The relationship of H. pylori infection with region, occupation, drinking, and diet structure needs to be further studied.Background With advancements in the treatment of chronic liver disease (CLD), including liver transplantation (LT), quality of life and satisfaction after LT have become an important issue for pediatric patients and their parents. More evidence-based information is needed to describe and assess the impact of pediatric CLD on parents and the satisfaction of parents with treatment to better understand their needs. Aim To assess the satisfaction of parents of pediatric LT patients and that of parents of pediatric CLD patients. Methods During this survey, data were collected from parents of pediatric patients who underwent LT between January 2010 and April 2017 (LT group; n = 91) and parents of pediatric patients with chronic liver disease (CLD group; n = 94). Group comparisons were made based on the pediatric health-related quality of life (PedsQL) health care parent satisfaction scale, impact on family scale (IFS) and demographic characteristics. The PedsQL was administered to parents during a phone interview al impact, familial-social impact, personal strain, and total impact were consistently higher for the LT group (P less then 0.001). There were statistically significant relationships between education level, monthly income, and place of residence according to the IFS results but not the PedsQL results. There were inverse relationships between the difficulties that parents experience because of their child's health and education levels, monthly income, and place of residence. However, no relationship was found between education level, monthly income, or place of residence and satisfaction with health care services provided in the hospital according to the PedsQL results. Conclusion Parents of children who underwent LT were very satisfied with the health care services provided to their children. However, they had more difficulties than parents of children with CLD.Background Vitamin D deficiency is common in patients with chronic pain and healthy people, but the difference between the two has not been reported; thus, whether there is a relationship between vitamin D deficiency and chronic pain remains to be confirmed. Osteoporosis is a common disease in chronic pain disorders. Understanding the relationship between vitamin D and osteoporosis will provide a basis for the rational supplementation of vitamin D to prevent osteoporosis, and to understand the risk factors of bone mass change to provide a new treatment plan for early prevention of osteoporosis. Aim To determine 25 hydroxy vitamin D (25OHD) level in patients with chronic pain to clarify its clinical significance. The relationship between vitamin D and bone mineral density (BMD) and the risk factors for bone mass change were also evaluated. Methods In this study, 184 patients with chronic pain were included in the study group, and 104 healthy individuals who underwent routine health checkups during the same pere above results were analyzed statistically and showed significant differences (P less then 0.05). There was a positive correlation between age and BMD in patients with chronic pain (R = 0.567, P less then 0.001). Age, PTH and Ca were risk factors for bone mass reduction, while age, ethnicity and altitude were risk factors for osteoporosis. Conclusion Vitamin D deficiency is a common phenomenon in patients with chronic pain, and severe vitamin D deficiency is not uncommon. Vitamin D level is not a risk factor for bone mass reduction and osteoporosis. Bone mass reduction is correlated with age, PTH and Ca, while osteoporosis is correlated with age, ethnicity and altitude.Background Hemodialysis is an advanced blood purification technique to manage kidney failure. However, for conventional hemodialysis, the high prevalence of dyslipidemia may cause cardiovascular diseases and an increase in mortality.  https://www.selleckchem.com/products/ABT-888.html  Moreover, toxins accumulating in the body over time may induce some complications. High flux hemodialysis can effectively improve disease indexes and clinical symptoms. Aim To investigate the efficacy of high flux hemodialysis in elderly patients with chronic kidney failure (CKF). Methods A total of 66 elderly patients with CKF who were admitted to our hospital from October 2017 to October 2018 were included in the study. According to the therapies they received, the patients were divided into a study group and a control group with 33 patients in each group. The study group received high flux hemodialysis and the control group received conventional dialysis treatment. Kidney function, toxin levels in serum, and complications were compared in the two groups. Results Before the treatment, there was no significant difference in kidney function, β2-microglobulin, or blood urea nitrogen between the two groups (P > 0.05). In contrast, kidney function was better in the study group than in the control group after the treatment (P less then 0.05). In addition, the study group had significantly lower parathyroid hormone and serum cystatin C than the control group (P less then 0.05). The incidence of complications was 8.57% in the study group, which was lower than that of the control group (20.00%; P less then 0.05). Conclusion High flux hemodialysis may improve kidney function and reduce toxin levels in serum and the incidence of complications in elderly patients with CKF.
