AIM To observe the effects of Huangdi Anxiao Capsules (Puerariae lobatae Radix,Eriobotryae Folium,Notoginseng Radix et Rhizoma,etc.) on blood glucose and insulin resistance in GK rats with type 2 diabetes mellitus (T2DM) and its possible mechanism of action.METHODS GK rats with T2DM included in the experiment were randomly divided into model group,rosiglitazone (1.44 mg/kg) group,Shenqi Jiangtang Granules (1.08 g/kg) group,Huangdi Anxiao Capsules high,medium and low (12,6,3 g/kg) group and normal control group of Wistar rats.After six weeks of consecutive administration,fasting blood glucose (FBG),serum insulin (FINS),fasting plasma glucose (FPG),and insulin resistance index (HOMA-IR) were measured in all groups.Serum biochemical indexes of (TG,TC,HDL-C,LDL-C),glycosylated hemoglobin (HbA1c),glucagon-like peptide (GLP-1) and insulin-like growth factor (IGF-1) were measured.The pancreatic tissue was obtained by routine paraffin embedding and HE staining to observe the pathological changes.RESULTS Compared with the normal group,FBG,FPG,FINS,HOMA-IR,TG,TC,HDL-C,LDL-C and HbA1c of the model group were significantly higher (P <0.01),and GLP-1 and IGF-1 expressions were markedly decreased (P < 0.01).Compared with the model group,the levels of FBG,FPG,FINS,HOMA-IR,TG,TC,HDL-C,LDL-C and HbA1 c in Huangdi Anxiao Capsules high-,medium-and low-dose group were significantly decreased (P < 0.05,P <0.01);GLP-1 and IGF-1 expressions were markedly increased (P <0.05,P <0.01),compared with the model group,the structure changes of pancreatic tissue in Huangdi Anxiao Capsules high-,medium-and low-dose groups largely reduced.CONCLUSION Huangdi Anxiao Capsules can reduce GK rats fasting blood glucose,insulin resistance,and its mechanism may be related to promoting the emergence and proliferation of pancreatic islet cells,improving the function of islet beta cells,and increasing insulin secretion.

Objective:To investigate the clinical efficacy of butylphthalide combined with hyperbaric oxygen therapy on post-stroke cognitive impairment in patients with acute ischemic stroke.Methods:A total of 90 patients with post-stroke cognitive impairment who were hospitalized within 72 hours of onset in Suining County People's Hospital from December 2019 to November 2020 were included in this study. They were randomly divided into a control group and an observation group ( n = 45/group). The control group was given conventional treatment and the observation group was given butylphthalide combined with hyperbaric oxygen therapy in addition to conventional treatment. The National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score were compared between the two groups before and after treatment. Results:Before treatment, there were no significant differences in the National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score between the two groups (all P > 0.05). At 14 days and 1 month after surgery, the National Institutes of Health Stroke Scale scores in the observation group were (4.02 ± 2.18) points and (3.21 ± 2.03) points, which were significantly lower than (5.21 ± 2.24) points and (4.62 ± 2.68) points in the control group ( t =2.55, 2.81, both P < 0.05). At 1 and 3 months after treatment, the Montreal Cognitive Assessment score in the observation group were (19.79 ± 5.67) points and (23.69 ± 2.67) points, which were significantly higher than (16.88 ± 5.12) points and (19.74 ± 2.29) points in the control group ( t = 2.56, 7.53, both P < 0.05). At 1 and 3 months after treatment, Activities of Daily Living scores in the observation group were (54.85 ± 5.69) points and (74.38 ± 4.98) points, which were significantly higher than (46.78 ± 6.24) points and (63.21 ± 5.24) points in the control group ( t = 6.41, 9.76, both P < 0.05). Conclusion:Butylphthalide combined with hyperbaric oxygen therapy for the treatment of post-stroke cognitive impairment in patients with acute ischemic stroke can alleviate neurologic deficits, and improve cognitive function and the ability of daily life.
