ABSTRACT
Ferroptosis is a novel type of cell death which induced by iron-dependent lipid peroxidation accumulation. This type of cell death is significantly different from other cell death in terms of morphology, genetics and biochemistry. It has been reported that ferroptosis is involved in a variety of human diseases, particularly in liver diseases. Therefore, screening and studying of inhibitors or activators of ferroptosis may provide novel strategies for prevention and treatment of liver diseases. This review provides the biological characteristics and regulatory signaling pathways of ferroptosis, as well as the relationship between ferroptosis and liver diseases, which will contribute to new insight into the pathogenesis of liver diseases.
ABSTRACT
Objective To analyze the impact of comprehensive care on living conditions of hemophiliac patients in China.Methods Based on the managerial experience of the World Federation of Hemophilia(WFH) and China's national condition,we carried out comprehensive care on patients with hemophilia (PWH) in our center.Questionnaire surveys on living condition were conducted before and after intervention (in 2004 and 2016,respectively) to Beijing's permanent hemophiliacs.The results of questionnaires conducted in 2004 were settled as baseline data,and a comparative analysis was done between the baseline data and the results of surveys conducted in 2016 in the PWH who had received comprehensive care for at least 2 years.Results Totally 109 cases received baseline survey whereas 136 cases received questionnaires after intervention.Thirty-nine(28.7％) and 70(51.5％) patients conducted prophy-laxis or home treatment after receiving comprehensive care,respectively.There was significant difference (P＜0.01)in terms of treatment timeliness.Similar results were found (P＜0.01)in terms of times of bleeding per year,and there was significant improvement (P＜0.01) on joint disorder after comprehensive care.Conclusion After receiving comprehensive care,PWH are more willing to accept and conduct prophylaxis and home treatment.The bleeding can be controlled more effectively,and the treatment can be given more timely.Meanwhile,PWH can receive more improvements in joint and walking function.

ABSTRACT
In this study, we sought to determine the association between environmental factors and nonsyndromic cleft of the lip and/or palate (NSCLP) to understand the etiology of the disease. A total of 200 NSCLP cases and 327 controls were recruited at the Maternal and Child Health Hospital of Xuzhou City. We conducted face-to-face interviews with the mothers of both cases and controls. The factors increasing the risk of NSCLP were a positive family history [odds ratio (OR)=56.74], pesticide exposure (OR=8.90), and indoor decoration pollution (OR=4.32). On the other hand, the factors decreasing the risk of NSCLP were a high education level (OR=0.22) and supplementation of folic acid (OR=0.23) and multivitamins (OR=0.16). Positive family history, pesticide exposure, and indoor decoration pollution are associated with the risk of NSCLP. In contrast, high education level and folic acid and multivitamin supplementation are protective factors against NSCLP.

A qualitative analytical method of liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry (HPLC-Q-TOF-MS) was developed for identification of multi-constituents and an analytical method was developed for simultaneously determining 4 major compounds (rutin, isoquercitrin, kaempferol-3-0-rutinoside, and astragalin) in Tetrastigma hemsleyanum Diels et Gilg. The HPLC-Q-TOF-MS assay was performed on a Welch Ultimate XB-C18 column (4.6 mm x 150 mm, 5 microm) with the mobile phase consisting of acetonitrile (A) and water containing 0.1% Formic acid (B) in gradient mode at a flow rate of 0.8 mL x min(-1). The column temperature was at 30 degrees C, and negative ion mode was used for TOF-MS. The UPLC-QqQ-MS assay was performed on a Waters CORTECS C18 (2.1 mm x 100 mm, 1.6 microm) with the mobile phase consisting of acetonitrile (A) and water containing 0.1% formic acid (B) in gradient mode at a flow rate of 0.25 mL x min(-1). The column temperature was at 45 degrees C, and MRM mode was used for QqQ-MS. Based on the retention time and MS spectra, 24 compounds were identified or tentatively characterized by comparing with reference substances or literatures. For quantitative the linear range of 4 detected compounds were good (r > 0.9966), and the overall recoveries ranged from 98.27% to 101.58%, with the RSD ranging from 3.15% to 5.88%. The results indicated that new approach conbined HPLC-Q-TOF-MS and UPLC-QqQ-MS was applicable in qualitative and quantitative quality control of Tetrastigma hemsleyanum.

In this study, a rapid and sensitive analytical method was developed for the determination of 10 major compounds (procyanidin B1, catechin, procyanidin B2, rutin, isoquercitrin, kaempferol-3-O-rutinoside, astragalin, quercitrin, quercetin, and kaempferol) in Tetrastigma hemsleyanum by using ultra-performance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry (UPLC-MS/MS) in multiple-reaction monitoring (MRM) mode. UPLC-MS/MS assay with negative ion mode was performed on a Waters CORTECS C18 (2.1 mm x 100 mm, 1.6 μm) with the mobile phase consisting of acetonitrile (A) and 0.1% aqueous formic acid (B) in gradient elution at a flow rate of 0.25 mL · min(-1) and the column temperature was set at 45 °C. Under the optimized chromatographic conditions, good separation for 10 target compounds were obtained including chiral isomer procyanidins B1 and B2 were completely separated within 8.5 min. Satisfactory linearity was achieved with wide linear range and fine determination coefficient (r > 0.996 6), the overall recoveries were ranged from 95.44%-110.40% with the RSD ranging from 2.37%-8.69%. It is the first report about simultaneous analysis of 10 major flavonoids components in Tetrastigma hemsleyanum by using UPLC-MS/MS method, which affords highly sensitive, specific, speedy and efficient method for quality control of Tetrastigma hemsleyanum
