Objective To explore the feasibility of blood oxygen level-dependent (BOLD) MRI to detect the chronic hepatitis b-induced early kidney injury. Methods Seventeen clinically diagnosed chronic hepatitis b patients with early kidney injury and 10 healthy volunteers were enrolled in this preliminary study. The 17 patients underwent dynamic nuclear renography and then subdivided into stage 1 kidney injury group (n=7) and stage 2 kidney injury group (n=10). All of the enrolled subjects underwent BOLD examination and T2* relaxation rates (R2*) of renal cortex and medulla of split kidney, and the ratio between them (R2*med/cor) were measured separately. One-way analysis of variance (ANOVA) were performed on the control group and chronic hepatitis b patients group (kidney injury stage 1 and stage 2 group) to compare the difference of renal cortical and medullary R2*values and R2*med/cor ratio. ROC curves were used to evaluate the efficacy of renal cortical and medullary R2* values and R2*med/cor ratio to diagnose the chronic hepatitis b-induced kidney injury. Results The cortical R2*values of control group, stage 1 kidney injury group and stage 2 kidney injury group were(16.87 ± 0.74)/s,(17.88 ± 0.73)/s,(20.29 ± 2.87)/s, respectively;the medullar R2*values of control group, stage 1 kidney injury group and stage 2 kidney injury group were (28.07±1.03)/s,(31.14±2.49)/s,(32.81±3.28)/s, respectively;R2*med/cor of the of control group, stage 1 kidney injury group and stage 2 kidney injury group were 1.67 ± 0.09, 1.75 ± 0.16, 1.63 ± 0.13, respectively, and the differences among the three groups were statistically significant (F values were 17.779, 19.170 and 3.439 , all P<0.05). Furthermore, the renal cortical and medullary R2* values of chronic hepatitis b patients were significantly higher than the control group, and the the renal cortical R2* value of the patients in stage 2 kidney injury group was also higher than the stage 1 kidney injury group. The area under curve (AUC) of ROC of the renal cortical and medullary R2*values and R2*med/cor to diagnose chronic HBV hepatitis-induced early kidney injury were 0.903, 0.949 and 0.526, respectively. Conclusion It's feasible and has great value to use renal BOLD MRI for the diagnosis of chronic hepatitis b-induced early kidney injury, and the renal cortex is more sensitive than the medulla to the kidney injury.

OBJECTIVE:To excavate and evaluate the security alert signals of linezolid after marketing,and to provide refer-ence for rational drug use in clinic. METHODS:The reporting odds ratio(ROR)method was used to excavate the security alert signals from the adverse drug events(ADE)data in the OpenFDA platform of FDA during second quarter of 2004-2016. The low-er limit of 95%CI >1 was regarded as suggestive of ADE alert signal. RESULTS:A total of 6828534 reports were extracted, among which there were 7224 reports mainly induced by linezolid. Top 10 ADE reports were thrombocytopenia,drug interac-tion,thrombocytopenia,nausea,anaemia,serotonin syndrome,diarrhoea,pyrexia,drug ineffective,vomiting. After the detec-tion of top 200 ADE reports by ROR method,120 signals related to 18 system organ class(SOC)were identified. Top 5 ADE sig-nals in turn by SOC were medical examination,nervous system disorders,blood and lymphatic system disorders,metabolism and nutrition disorders,cardiac disorders. The high risk signals with clinical reference value included 42 cases of optic neuropathy (ROR=56.33),350 cases of serotonin syndrome(ROR=52.86),162 cases of lactic acidosis(ROR=18.30),31 cases of endo-carditis (ROR=15.38),566 cases of thrombocytopenia (ROR=14.29),122 cases of bone marrow failure (ROR=14.20),261 cases of panhematopenia (ROR=11.92),86 cases of disseminated intravascular coagulation (ROR=10.91),58 cases of toxic epidermal necrolysis(ROR=9.06),etc. As for ADE reports,male was slightly higher than female,and the patients in age group of ≥45 reported evidently more compared to younger age group. CONCLUSIONS:By detecting and evaluating alert signals of li-nezolid through OpenFDA platform,we could effectively lay the foundation for further research of pharmacovigilance.

OBJECTIVE:To provide reference for developing zero-profit drug policy and compensation mechanism better in ur-ban public hospitals. METHODS:Taking a public hospital in a city as an example,effects of zero-profit drug policy on hospitals, patients,health insurance fund and single diseases with different drug proportions [cataract (2.94%) vs. chronic renal failure (38.77%)] were investigated by analyzing the canceled drug addition costs and adjusted medical service price data after developing zero-profit drug policy. RESULTS:After developing zero-profit drug policy,the overall compensation rate in the public hospital was 95.20%. The overall burden of urban patients was reduced,average burden cost was decreased 197.73 yuan every time;while the overall burden of urban and rural residents had increased,average burden cost was increased 17.39 yuan every time;and the overall burden of all patients had decreased. Health insurance fund had decreased,in which,the urban workers were decreased 151185500 yuan,and urban and rural residents were increased 4550400 yuan. In medical insurance for urban workers and health insurance for urban and rural residents,hospital increased by 7.00% and 8.99% in income in the treatment of cataract,the medical insurance fund increased by 12.07% and 13.67%,and patients'burden increased by 0.58% and 3.43%,respectively. For chronic renal failure,hospital income increased by 3.23% and 3.93%,medical insurance fund decreased by 3.19% and 3.96%,and pa-tients'burden decreased by 4.27% and 3.63%,respectively. CONCLUSIONS:Zero-profit drug policy is the ideal measure for get-ting rid of"drug-maintaining-medicine". When developing the policy,it should be combined with actual situation and different dis-eases to explore adjustment of medical service prices,reasonable financial compensation models and medical insurance payment mechanism.

Objective:To evaluate the role of signal transducer and activator of transcription 3 (STAT3)/nuclear receptor coactivator 4 (NCOA4)-mediated ferritinophagy in salidroside-induced attenuation of intestinal ischemia-reperfusion (I/R) injury in mice and the relationship with ferroptosis.Methods:Thirty-six SPF-grade healthy male C57BL mice, aged 6-8 weeks, weighing 20-25 g, were divided into 6 groups ( n=6 each) by a random number table method: sham operation group (S group), sham operation+ salidroside group (SS group), intestinal I/R group (IR group), intestinal I/R+ salidroside group (IS group), intestinal I/R+ salidroside+ autophagy activator rapamycin group (ISR group) and intestinal I/R+ salidroside+ STAT3 activator colivelin group (ISC group). The intestinal I/R injury model was established by clamping the superior mesenteric artery for 45 min followed by 30-min reperfusion in IR, IS, ISR and ISC groups, while the superior mesenteric artery was only isolated without clipping in S and SS groups. At 1 week before developing the model, salidroside 40 mg/kg was intraperitoneally injected once a day for 7 consecutive days in SS, IS, ISC and ISR groups, rapamycin 4 mg/kg was intraperitoneally injected once a day for 7 consecutive days in group ISR, colivelin 1 mg/kg was intraperitoneally injected once a day for 7 consecutive days in group ISC, while the equal volume of normal saline was given instead in the rest two groups. The mice were sacrificed at 30 min of reperfusion, and intestinal tissues were obtained for examination of the pathological changes after HE staining (with a optical microscope) which were scored according to Chiu and for determination of contents of malondialdehyde (MDA), Fe 2+, glutathione (GSH) and reactive oxygen species (ROS), activity of superoxide dismutase (SOD) and expression of p-STAT3, STAT3, glutathione peroxidase 4 (GPX4), NCOA4 and ferritin heavy chain 1 (FTH1) in intestinal tissues (by Western blot). Results:Compared with group S, the Chiu′s score and contents of MDA, Fe 2+ and ROS were significantly increased, the content of GSH was decreased, the activity of SOD was decreased, the expression of p-STAT3 and NCOA4 was up-regulated, the expression of GPX4 and FTH1 was down-regulated, the p-STAT3/STAT3 ratio was increased ( P<0.05), pathological injury was found in intestinal tissues, and no significant change was found in the aforementioned indexes in group IR( P>0.05). Compared with group IR, the Chiu′s score and contents of MDA, Fe 2+ and ROS were significantly decreased, GSH content was increased, SOD activity was increased, the expression of p-STAT3 and NCOA4 was down-regulated, the expression of GPX4 and FTH1 was up-regulated, p-STAT3/STAT3 ratio was decreased ( P<0.05), and the pathological injury was significantly alleviated in intestinal tissues in group IS. Compared with group IS, the Chiu′s score and contents of MDA, Fe 2+ and ROS were significantly increased, GSH content was decreased, SOD activity was decreased, the expression of p-STAT3 and NCOA4 was up-regulated, the expression of GPX4 and FTH1 was down-regulated, p-STAT3/STAT3 ratio was increased ( P<0.05), and the pathological injury was aggravated in intestinal tissues in ISR and ISC groups. There was no statistically significant difference in the expression of STAT3 among the five groups ( P>0.05). Conclusions:STAT3/NCOA4-mediated ferritinophagy is involved in the process of salidroside-induced reduction of intestinal I/R injury in mice, which may be related to inhibiting ferroptosis.
