Study on rat intestinal absorption characteristics of total flavonoids from Coreopsis tinctoria / 中国中药杂志

The rat everted intestinal sac model was adopted to investigate the absorption of total flavonoids from Coreopsis tinctoria in different intestinal segments. Cyaniding-3-O-β-D-glucoside, chlorogenic acid, flavanomarein, quercetagetin-7-O-β-D-glucoside, iso-okanin, marein and 3,5-dicaffeoylquinic acid which as the major chemical components of total flavonoids from C. tinctoria were selec-ted as the study objects to evaluate the absorption characteristics of each component in different intestinal segments. The results showed that the absorption of seven components of total flavonoids at different intestinal segments was in consistent with zero order absorption rate. The K_a of chlorogenic acid, flavanomarein, quercetagetin-7-O-β-D-glucoside, isookanin and 3,5-dicaffeoylquinic acid increased with increasing of concentration of total flavonoids(P<0.05), indicating that the intestinal absorption of these five components was passive transport. The K_a of cyaniding-3-O-β-D-glucoside and marein showed a weak concentration dependence, suggesting that the absorption of them may be an positive and passive co-existing mode. The result of absorption in different intestinal segments showed that cyaniding-3-O-β-D-glucoside, chlorogenic acid, flavanomarein, quercetagetin-7-O-β-D-glucoside, marein and 3,5-dicaffeoylquinic acid were mainly absorbed in ileum, while isookanin was mainly absorbed in jejunum. The total flavonoids of C. tinctoria are selectively absorbed in intestinal tract, the rat everted intestinal sac model can be used to evaluate the multi-component intestinal absorption characteristics of total flavonoids from C. tinctoria.

Long-term positive severe acute respiratory syndrome coronavirus 2 ribonucleic acid and therapeutic effect of antivirals in patients with coronavirus disease: Case reports

Abstract Coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been declared a pandemic. We herein report four COVID-19 cases with long-term positive viral ribonucleic acid (RNA) for about 61 days. Despite treatment with recombinant human interferon, convalescent plasma from COVID-19 patients, arbidol, etc., nucleic acid results were still positive for SARS-CoV-2. After treatment with ritonavir-boosted danoprevir (DNVr, 100/100 mg, once daily), all four patients showed two to three consecutive negative SARS-CoV-2 RNA and were thus discharged from hospital. Therefore, DNVr may be a potentially effective antiviral for COVID-19 patients with long-term positive SARS-CoV-2 RNA.

Recurrent Hyperammonemia After Abernethy Malformation Type 2 Closure: a Case Report

ABSTRACT The Abernethy malformation is a rare congenital malformation defined by the presence of an extrahepatic portosystemic shunt. Although most patients are asymptomatic, clinical encephalopathy is present in 15% of cases. We present a patient with type 2 Abernethy malformation, hyperammonemia, and encephalopathy. Shunt closure was performed successfully using interventional angiography; however, hyperammonemia recurred 3 months later. The diagnosis of Abernethy malformation can be made easily, but the ideal patient management strategy has not yet been established. This is the first reported patient with recurrence of hyperammonemia after interventional treatment; we discuss the therapeutic options for Abernethy malformation.(AU)

Thickness measurement of frequency domain OCT on photoreceptor cell layer in diabetic retinopathy / 国际眼科杂志(Guoji Yanke Zazhi)

·AIM:To compare the outer nuclear layer ( ONL) , inner and outer segments (IS/OS), photoreceptor cell layer in healthy people and diabetic retinopathy by frequency-domain optical coherence tomography ( OCT) .·METHODS: Totally 100 eyes of 50 healthy people were selected as control group. According to conventional mydriasis for examination of fundus and fundus fluorescein angiography ( FFA ) examination, all diabetic cases were divided into 3 groups: normal retina group ( NDR ) , non - proliferative diabetic retinopathy group (NPDR), proliferative diabetic retinopathy group (PDR). Using OCT measure the thickness of ONL, IS/OS and photoreceptor cell layer of fovea and parafovea ( nasal side and temporal side) in the four groups.·RESULTS: Compared with the control group, the ONL and photoreceptor cell layer's thickness of macular fovea and temporal parafovea in NPDR group and PDR group were statistically significant(all P<0. 05). The differences between ONL and photoreceptor cell layer's thickness of macular fovea and temporal parafovea in NDR group and PDR group were not statistically significant(P>0. 05). The IS/OS of macular fovea and temporal parafovea was not significantly different among those groups (P>0. 05). The thickness of different layers of nasal parafovea were not different (P>0. 05).·CONCLUSION: The thickness of macular fovea and temporal parafovea has relation with degree of DR; the change of photoreceptor cell layer's thickness occurs mainly in ONL, but IS/OS no change; the change in temporal parafovea more obvious than in nasal parafovea. Frequency-domain OCT can quantitatively and qualitatively observe the subtle diabetic macular changes in diabetic patients with macular disease, and provides a reliable detection for the early diagnosis and treatment.
