ObjectiveTo validate the alleviating effect of Gegen Qinliantang (GGQLT) on insulin resistance in db/db diabetic mice by regulating the silent information regulator 1 (SIRT1)/forkhead transcription factor O1 (FoxO1) autophagy pathway. MethodSeventy-five SPF-grade spontaneous type 2 diabetic db/db mice and 15 control db/m mice were selected and maintained on regular feed for one week before measuring blood glucose. They were randomly divided into six groups, with 15 mice in each group. The groups included a normal group (physiological saline, 0.2 g·kg-1), a metformin group (0.2 g·kg-1), high-, medium-, and low-dose GGQLT groups (31.9, 19.1, 6.9 g·kg-1), and a model group (physiological saline, 0.2 g·kg-1). They were orally treated with corresponding drugs for eight weeks, once daily. Fasting blood glucose (FBG) was measured using a Roche glucometer. Serum levels of high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and total cholesterol (TC) were measured using an automated biochemical analyzer. Fasting serum insulin (INS) levels were determined using enzyme-linked immunosorbent assay (ELISA), and the homeostasis model assessment of insulin resistance (HOMA-IR) was calculated. Western blot was used to detect the expression of Beclin-1, microtubule-associated protein 1 light chain 3 (LC3), and SIRT1/FoxO1 autophagy pathway-related proteins in liver tissues. Immunohistochemistry was performed to assess the expression of SIRT1, FoxO1, Beclin-1, and LC3B proteins in liver tissues. Transmission electron microscopy was used to observe the formation of autophagosomes in the liver. ResultCompared with the normal group, the model group showed significant increases in FBG, FINS, HOMA-IR, TC, TG, LDL-C, and HDL-C levels (P<0.01), and significant increases in the expression of SIRT1, Beclin-1, LC3, and FoxO1 proteins in liver tissues (P<0.01). Transmission electron microscopy revealed the highest number of autophagosomes in the model group. Compared with the model group, the metformin group and the low-, medium-, and high-dose GGQLT groups showed significant decreases in serum FBG, FINS, HOMA-IR, TC, TG, LDL-C, and HDL-C levels (P<0.05, P<0.01), significant decreases in the expression of SIRT1, Beclin-1, LC3 (P<0.05, P<0.01), and up-regulated FoxO1 protein (P<0.01). Transmission electron microscopy showed a reduction in the degree of autophagy in the treatment groups. Compared with the metformin group, the medium- and high-dose GGQLT groups showed significant decreases in FBG, FINS, and TG levels (P<0.01), significant decreases in the expression of SIRT1, Beclin-1, and LC3 in liver tissues (P<0.05, P<0.01), and reduced FoxO1 protein (P<0.01). The high-dose GGQLT group showed reduced HOMA-IR, TC, LDL-C, and HDL-C levels (P<0.05, P<0.01). Transmission electron microscopy revealed a significant reduction in autophagosomes in the medium- and high-dose GGQLT groups. ConclusionGGQLT can significantly improve glucose and lipid metabolism disorders, alleviate insulin resistance in db/db mice, and prevent and treat type 2 diabetes by activating the SIRT1/FoxO1 autophagy pathway.

Dysglycemia is independently associated with the mortality of critically ill patients. Therefore, the management of blood glucose plays an important role in comprehensive therapy. It is suggested that the same target value of blood glucose (7.8-10.0 mmol/L) should not be set for all critically ill patients. Instead, it should be individually set based on the causes of the patient's admission and the status of blood glucose before admission. For this reason, there is an urgent need for a convenient protocol and method to regulate the dosage of insulin. The first hospital of Jiaxing, collaborating with information engineers, developed a modified eProtocol-insulin for domestic population with mathematical modeling and developed an Application Software (APP), which is convenient for clinical use. This is the first eProtocol-insulin and smart device APP for critically ill patients in China.

Objective To explore the changes of corticotropin releasing factor (CRF) levels secreted by hypothalamus neuron in children with acute brain injury. Methods Fifty-one intracranial-infection children with brain injury and 11 intracranial-noninfection children with brain injury were chosen from pediatric intensive care unit of our hospital. Severities of their brain damage were evaluated by Glasgow score,and CRF level in cerebrospinal fluid (CSF) and serum TNF-α and IL-6 levels were measured by radioimmunoassay. Results There was no significant difference of Glasgow scores between the intracranial infection group and intracranial-noninfection group ( P = 0. 302 6 ), CSF CRF level of intracranial infection group was significantly lower than that of intracranial-noninfection group ( P < 0. 01 ), serum TNF-α and IL-6 levels of intracranial infection group were significantly higher than those of intracranial-noninfection group ( P < 0. 01,P <0. 001 ). As comparing to the children with Glasgow score of 6 ~ 7, the levels of CSF CRF and serum TNF-α and IL-6 in children with Glasgow score of 4 ~ 5 were significantly increased ( P < 0. 05, P < 0. 001 ).Conclusion CSF CRF level of the children with acute brain injury is changing, which may be concerned with the secretion of hypothalamus CRF neuron stimulated by TNF-α, IL-6 and hypoxia stress in children with brain injury.
