In the original published version of this article, the reference to the article by the author group, which shares common data with this article, was not included. The newly added reference no. 42 now acknowledges this previous work, and the authors have indicated the overlaps between the two articles. The authors have also replaced Fig 1.D as due to error the vertical axis contained incorrect additional text and the horizontal axis is found to be missing units.
The original section 2.1 can be found below:
“2.1 Mice experiments
The db/db mice (male, 2 months old, among 40.00 g) and m/m mice (among 20.00 g) were bought from Changzhou Cavens Experimental Animal Co., Ltd. All animals raised under SPF conditions. After one week of acclimatization, they were assigned to model (DM), berberine (n = 7), and normal control (NC, n = 10) groups. The dose of berberine (Yuanye Bio-Technology Co., Ltd) administered was 0.2 g/kg⋅BW. The model and control groups given equal volume clean water. Treatments continued for 6 weeks.”
The authors have updated section 2.1 to include an additional reference numbered [42] acknowledging their previous work and indicating overlaps. The correct version of the section should be as below:
“2.1 Mice experiments
2.1 Mice experiments
The experimental design was similar to that described in our previously published study [42], with data for the normal control group (NC) and the diabetes model group (DM) being shared between both studies. This study is part of a larger project aimed at evaluating and screening the hypoglycemic effects of six compounds, including Polygonatum sibiricum polysaccharide [42] and others (not yet published). The NC and DM groups received no special treatment other than water, serving as controls for normal and naturally occurring diabetes conditions. Since the data for the NC and DM groups are shared between this study and our previous publication [42], there are overlaps in Table 1, and Figures 1, 2, 3, 4, and 5.
Briefly, the db/db mice (male, 2 months old, among 40.00 g) and m/m mice (among 20.00 g) were bought from Changzhou Cavens Experimental Animal Co., Ltd. All animals raised under SPF conditions. After one week of acclimatization, the db/db mice were assigned to DM (n = 7), and berberine (n = 7) groups, and the m/m mice were assigned to normal control NC (n = 10) group. The dose of berberine (Yuanye Bio-Technology Co., Ltd) administered was 0.2 g/kg·BW. The model and control groups given equal volume clean water. Treatments continued for 6 weeks.
The original Fig 1.D is as below.
Fig. 1. Impact of berberine on diabetes. A, Glucose in blood; B, Glucose in serum; C, Glucose in urine; D, Oral glucose tolerance; E, Area under curve; F, glycated serum protein; G, insulin; H, Leptin; I, nonesterified fatty acid, ∗p < 0.05.
The authors have replaced the incorrect text on the vertical axis to read ‘Blood glucose (mmol/L) and corrected the missing units on the horizontal axis adding ‘Time (min). The correct version of Fig. 1D can be found below.
