Diabetic nephropathy is one of the major complications of T2DM. In the current study, we examined the potential protective effects of LX and TC on experimentally induced diabetic nephropathy in T2DM rats and their possible molecular mechanisms. To examine this possibility, rats were fed a high-fat diet (HFD) for 12 weeks, followed by a single injection of 35 mg/kg streptozotocin (STZ) to induce T2DM. 10 μg/kg LX and 25 mg/kg TC were given alone or in combination to T2DM rats for 4 weeks. The kidney examination of T2DM rats showed clear deterioration. T2DM rats exhibited significantly higher body weight, blood glucose, hemostatic model assessment for insulin resistance (HOMA-IR), blood urea nitrogen (BUN), serum creatinine, kidney reactive oxygen species (ROS), nuclear factor-κ B (NF-κ B), and transforming growth factor-β (TGF-β ), and significantly lower serum insulin, urine creatinine, creatinine clearance (CRCL), kidney superoxide dismutase (SOD), glutathione reduced (GSH), nuclear factor erythroid 2 (NrF₂ ), heme oxygenase-1 (HO-1), and endothelial nitric oxide synthase (eNOS) when compared to control rats. Single treatment with LX or TC showed obvious ameliorative effects on kidney complications in T2DM rats, with more ameliorative effects with the combined administration of both drugs.

We present the findings of a retrospective study conducted at the International University of Health and Welfare Narita Hospital (referred to as \"our hospital\") that aimed to identify risk factors linked to the occurrence of irAEs. The study focused on analyzing various factors, including therapeutic and lifestyle backgrounds, as well as laboratory values of patients who received ICI treatment and were subsequently diagnosed with irAE. The study included patients who met the eligibility criteria for ICIs (both single agent and combination therapy) as well as ICI in combination with anticancer drugs. The inclusion period for the study encompassed April 2020 to May 2022 at our hospital. The fifty patients were divided into two groups based on the severity of irAEs: the first group consisted of patients with irAE Grade 2 or lower (referred to as irAE Grade under 2), while the second group included patients with irAE Grade 3 or higher (referred to as irAE Grade over 3). Statistical analysis revealed significant differences in age (p=0.027) and CRP (C-reactive protein) levels (p=0.008) among the background factors when comparing the two groups. Additionally, statistically significant differences were observed among different ICI treatment groups in the occurrence of irAEs (p=0.035). however, it was indicated to be a relatively weak correlation. Moving forward, we shifted our focus to examine the frequency of irAEs in relation to exposure. However, we did not observe any significant correlation between exposure and irAE grade. Additionally, even when exposure was doubled through the use of ipilimumab in combination with ICIs (referred to as \"Mod exposure\"), no correlation was found. Exposure was further categorized into three groups: the PD-1 group, PD-L1 group, and PD-1 + CTLA-4 group. However, no significant correlation was observed between exposure in any of these groups and the grade of irAEs. Similarly, no significant correlation was observed between the dosage of ICI in the fixed-dose group and the weight-based dosage group with exposure and irAE Grade.

The flavonoid glycoside baicalin has been described in the literature to be metabolised by the intestinal microbiota. The aim of this work was to investigate how the biotransformation of baicalin to baicalein is related to the intestinal microbiota. For this purpose, stool samples from healthy volunteers with different dietary habits were used. From the pre-cultured stool samples, different standard microbiota were obtained which were used for the subsequent metabolism studies in the <i>in vitro</i> model MimiCol. MimiCol represents the ascending section of the colon, the <i>colon ascendens</i>, in terms of available volume, pH-value, redox potential and bacterial abundance. While during the experiments with added standard microbiota a metabolism of baicalin to baicalein could be detected, this was not the case in a series of experiments without added microbiota. This confirmed the hypothesis that the metabolism of baicalin relies on the bacterial species that are present in the colon. The data collected in the MimiCol therefore support the use of baicalin as a potential marker for the determination of the colon arrival. This can be explained by the fact that baicalin in its native form is poorly absorbed from the gastrointestinal tract. Enzymes of the colonic microbiota, namely β-glucuronidases, hydrolyze baicalin to the aglycone baicalein. The resulting aglycone can be absorbed through the intestinal mucosa and detected in blood plasma.
