RESUMEN
Currently, the most widely used screening methods for hyperuricemia (HUA) involves invasive laboratory tests, which are lacking in many rural hospitals in China. This study explored the use of non-invasive physical examinations to construct a simple prediction model for HUA, in order to reduce the economic burden and invasive operations such as blood sampling, and provide some help for the health management of people in poor areas with backward medical resources. Data of 9252 adults from April to June 2017 in the Affiliated Hospital of Guilin Medical College were collected and divided randomly into a training set (n = 6364) and a validation set (n = 2888) at a ratio of 7:3. In the training set, non-invasive physical examination indicators of age, gender, body mass index (BMI) and prevalence of hypertension were included for logistic regression analysis, and a nomogram model was established. The classification and regression tree (CART) algorithm of the decision tree model was used to build a classification tree model. Receiver operating characteristic (ROC) curve, calibration curve and decision curve analyses (DCA) were used to test the distinction, accuracy and clinical applicability of the two models. The results showed age, gender, BMI and prevalence of hypertension were all related to the occurrence of HUA. The area under the ROC curve (AUC) of the nomogram model was 0.806 and 0.791 in training set and validation set, respectively. The AUC of the classification tree model was 0.802 and 0.794 in the two sets, respectively, but were not statistically different. The calibration curves and DCAs of the two models performed well on accuracy and clinical practicality, which suggested these models may be suitable to predict HUA for rural setting.

A bottom-up approach was developed to prepare TEMPO radical decorated hollow aromatic frameworks (HPAF-TEMPO) by using TEMPO radical functionalized monomers and SiO2 nanospheres as templates. The accessible inner layer, high density of TEMPO sites, and hybrid micro-/mesopores of the HPAF-TEMPO enable the aerobic oxidation of a broad range of alcohols with high efficiency and excellent selectivity.
RESUMEN
OBJECTIVE: To study the clinical therapeutic effects and safety of Fufang Biejia Ruangan tablet (FBRt) in patients with chronic hepatitis B complicated with hepatic fibrosis. METHODS: Totally 420 patients were randomly divided into two groups, FBRt group (300 cases) were treated with Fufang Biejia Ruangan tablets and control group (120 cases) were treated with He Luo Shu Gan capsule, the patients in both groups were treated for 6 months. RESULTS: The cure rate and total effective rate of FBRt group were significantly higher than those of control group (55.67 percent and 81.67 percent vs. 15.8 percent and 60.00 percent, P less than 0.01). CONCLUSION: Fufang Biejia Ruangan tablet could alleviate clinical symptoms and hepatic fibrosis. Fufang Biejia Ruangan tablet is effective and safe in treatment of patients with chronic hepatitis B complicated with liver fibrosis.
