In Arab region, bloodletting therapy is called Al-Hijamah which is analogous to the bloodletting and cupping in traditional Chinese medicine. However, Al-Hijamah therapy has its own characteristics which are analyzed emphatically in this report, including strict operating procedure, prominent mental effect, emphasis on bloodletting time, extensive indications, definite contraindications and so forth.展开更多

Therefore, we conducted a prospective cohort study to evaluate the association be-tween occult HBV infection and CKD. Methods: A total of 4329 adults, aged 46.2 ± 13.7 years, without CKD at baseline were enrolled while undergoing physical examinations. Occult HBV infection was defined as seropositivity for antibody to HBV core antigen. CKD was defined as decreased estimated glomerular filtration rate (eGFR<60 ml$min?1$1.73 m?2) or presence of proteinuria ?1t, assessed using a repeated dipstick method. eGFR was computed using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Results: The prevalence of occult HBV infection was 8.1% (352/4329). During 5 years of follow-up, 165 patients (3.8%) developed CKD. Univariate Logistic regression analysis showed that occult HBV infection was positively associated with decreased eGFR, with an odds ratio (OR) of 2.15 (95%confidence interval (CI):1.05e4.11). In contrast, occult HBV infection was not associated with either proteinuria or CKD (P>0.05). After adjustment for potential confounders in the multivariate Logistic regression analysis, age, hypertension, diabetes, and the highest quartile of uric acid were associated with CKD, with ORs of 1.04 (95%CI:1.02e1.05), 2.1 (95%CI:1.46e3.01), 2.02 (95%CI:1.36e2.99), and 1.86 (95%CI:1.17e2.95), respectively. However, occult HBV infection was not associated with CKD, with an OR of 1.12 (95%CI:0.65e1.95). Conclusions: This study did not find an association between occult HBV infection and CKD. However, high-risk patients infected with HBV should still be targeted for monitoring for the development of CKD.展开更多
