Clinical analysis of two diagnosis methods for herb-induced liver injury / 中国中药杂志

To compare the consistency and difference of herb-induced liver injury between two methods in guidelines for clinical diagnosis and treatment of liver injury related to Chinese herbal medicine in China (2016) and guidelines for the diagnosis and treatment of drug-induced liver injury in China(2015). This retrospective analysis included 390 patients with herb-induced liver injury who had a history of suspicious Chinese herbal medicines or patent medicines; the patients with integrative Chinese and western medicines were excluded from this study. The results indicated that there were 14(4%) extremely probable patients (>8 points), 185(47%) highly probable patients (6-8 points) and 191(49%) probable patients(3-5 points) in 390 cases with guidelines for diagnosis and treatment of drug-induced liver injury of China (2015). While when guidelines for clinical diagnosis and treatment of liver injury related to Chinese herbal medicine in China (2016) was used for 390 patients, the results indicated that there were 5 (1%) cases with proven diagnosis, 163(42%) cases with clinical diagnosis, and 222(57%) cases with suspected diagnosis. Statistics showed that two methods had a consistency of 43% and difference of 14%. The research results showed that Guidelines for clinical diagnosis and treatment of liver injury related to Chinese herbal medicine in China(2016) was more suitable for the diagnosis of herb-induced liver injury. Due to the limitations of retrospective case study, further more prospective studies would be needed.

Clinical Analysis of Drug-induced Liver Injury Caused by Polygonum multiflorum and its Preparations / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To analyze hepatotoxicity of Polygonum multiflorum and clinical character- istics of drug-induced liver injury (DILI) caused by Polygonum multiflorum and its preparations.</p><p><b>METHODS</b>A retrospective study was performed in 158 patients treated at 302 Military Hospital between January 2009 and January 2014. All of them had used Polygonum multiflorum and its preparations before the onset of DILI, and their clinical characteristics and prognoses were analyzed.</p><p><b>RESULTS</b>Of the 158 DILI patients who used Polygonum multiflorum or its preparations, 92 (58.2%) combined with Western medicine or Chinese herbal preparations without Polygonum multiflorum; 66 patients (41.8%) used Polygonum mult florum and its preparations alone. In 66 DILI patients induced by Polygonum multiflorum or its preparations alone, 51 cases (77.3%) were induced by Polygonum multiflorum compounds and 22.7% by single Po- lygonum multiflorum; 4 cases (6.1%) were caused by crude Polygonum multiflorum and 62 (93.9%) by processed Polygonum multiflorum and its preparations. Clinical injury patterns were hepatocellular 92.4% (61 cases), cholestatic 1.5% (1 case), and mixed 6.1% (4 cases). Pathological examination was per- formed by liver biopsy in 32 cases (48.15%), manifested as hepatocellular degeneration and necrosis, fibroplasia, Kupffer cells with pigment granule, and a large number of eosinophil infiltration, were ob- served. Four patients were developed into liver failure, 4 into cirrhosis, and 1 died.</p><p><b>CONCLUSION</b>Polygo- num multiflorum and its preparations could induce DILI, but clinical diagnosis of Polygonum multiflorum induced hepatotoxicity should be cautious.</p>

Causes, Features, and Outcomes of Drug-Induced Liver Injury in 69 Children from China

BACKGROUND/AIMS: Drug-induced liver injury (DILI) is a frequent cause of pediatric liver disease; however, the data on DILI are remarkably limited. METHODS: All 69 children hospitalized with DILI between January 2009 and December 2011 were retrospectively studied. RESULTS: A total of 37.7% of the children had medical histories of respiratory infection. The clinical injury patterns were as follows: hepatocellular 89.9%, cholestatic 2.9%, and mixed 7.2%. Liver biopsies from 55 children most frequently demonstrated chronic (47.3%) and acute (27.3%) hepatitis. Hypersensitivity features, namely, fever (31.9%), rash (21.7%), and eosinophilia (1.4%), were found. Twenty-four children (34.8%) developed chronic DILI. Antibiotics (26.1%) were the most common Western medicines (WMs) causing DILI, and the major implicated herbs were Ephedra sinica and Polygonum multiflorum. Compared with WM, the children whose injuries were caused by Chinese herbal medicine (CHM) showed a higher level of total bilirubin (1.4 mg/dL vs 16.6 mg/dL, p=0.004) and a longer prothrombin time (11.8 seconds vs 17.3 seconds, p=0.012), but they exhibited less chronic DILI (2/15 vs 18/39, p=0.031). CONCLUSIONS: Most cases of DILI in children are caused by antibiotics or CHM used to treat respiratory infection and present with hepatocellular injury. Compared with WM, CHM is more likely to cause severe liver injury, but liver injury caused by CHM is curable.

Effects of Extremely Low Frequency Electromagnetic Fields on Lipid Peroxidation of Myocardium in Rats / 环境与健康杂志

ve To study the effects of extremely low frequency electromagnetic fields (ELF EMFs) on lipid peroxidation of myocardium in rats. Methods The activities of superoxide dismutase (SOD) and the contents of malonaldehyde (MDA) of the myocardium tissue of rats under the different conditions such as healthy state, my-ocardiac ischemic state and lead-exposure state before and after ELF EMFs exposure were determined respectively. Results ELF EMFs exposure didn't induce significant changes of SOD activities and MDA contents in myocardium of healthy rats, but caused the SOD activities of myocardium of lead-exposure rats to decrease from (31.24?1.08)U/mg prot before exposure to ELF EMFs to (29.20?1.14) U/mg prot after exposure to ELF EMFs (P
