The liver is closely associated with inflammation and the redox response， and inflammation is the body's innate defense system for clearing away harmful stimuli and participating in the liver's wound-healing response.Oxidative stress is associated with the activation of inflammatory pathways， and sustained inflammation and the corresponding regenerative wound healing response can induce fibrosis， cirrhosis， progression to end-stage liver disease or hepatocellular carcinoma， and ultimately death.Some "medicine and food homology" traditional Chinese medicine has been used in clinical effect， showing the ability to protect the liver.This paper reviewed the relationship between liver and oxidative stress response and inflammation response， and sorted out 110 "medicine and food same origin" traditional Chinese medicines based on the Chinese Pharmacopoeia（2020 edition） and the Chinese materia medica.The results showed that common floweringqince fruit， licorice root， cassia seed， emblic，seabuckthorn fruit，Chinese date， honeysuckle， ginger， cape jasmine fruit， platycodon root， lotus leaf， dandelion， reed root， honey， mountain honeysuckle， milkvetch root， glossy ganoderma， Gastrodia gastrodia and eucommia leaf were recorded to have liver protection effects.The liver protection mechanism is mainly anti-inflammatory， antioxidant and lipid peroxidation inhibition. Some Chinese herbs can also play a liver protection role by inhibiting the growth of hepatitis virus and liver cancer cells and regulating bile acid metabolism.In addition， the biological mechanism of its liver protection effect through antioxidant and anti-inflammatory effects in animal experiments was analyzed， and it was found that it plays a role through multiple pathways and multiple targets， providing new ideas for the role of "medicine and food homology" traditional Chinese medicine in the treatment strategy of liver diseases.

ObjectiveTo observe the effects of Hedysari Radix polysaccharide on the apoptosis of gastric sinus smooth muscle cells and explore the underlying mechanism via the insulin-like growth factor-1 （IGF-1）/phosphatidylinositol 3-kinase （PI3K）/serine-threonine kinase （Akt） pathway in the rat model of diabetic gastroparesis （DGP）. MethodSixty-two Wistar male rats were randomized into a blank group （n=12） and a modelling group （n=50）. The rat model of DGP was established by small-dose multiple intraperitoneal injections of streptozotocin combined with an irregular high-fat and high-sugar diet for 4 weeks. The modeled rats were randomized into model group， mosapride citrate （1.35 mg·kg^-1）， and high-， medium-， and low-dose （200， 100， and 50 mg·kg^-1， respectively） Hedysari Radix polysaccharide groups. The rats were administrated with corresponding drugs by gavage， and those in the blank and model groups with equal volumes of pure water by gavage once a day for 8 consecutive weeks. The random blood glucose and body mass were measured every 2 weeks， and gastric emptying rate was calculated. Hematoxylin-eosin （HE） staining was used to observe the pathological changes of smooth muscle in gastric antrum， and terminal deoxynucleoitidyl transferase-mediated nick-end labeling （TUNEL） was employed to detect the apoptosis of smooth muscle cells in the gastric antrum. The expression of IGF-1， phosphorylated （p）-PI3K， and p-Akt in the smooth muscle of gastric sinus tissue was detected by immunohistochemistry. Western blot was employed to determine the protein levels of IGF-1， p-PI3K/PI3K， p-Akt/Akt， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in the smooth muscle of the gastric antrum. ResultCompared with the blank group， the model group showed elevated random blood glucose at all time points （P<0.01）， decreased body mass and gastric emptying rate （P<0.01）， increased apoptotic index of smooth muscle cells in the gastric antrum （P<0.01）， down-regulated protein levels of IGF-1， p-PI3K/PI3K， p-Akt/Akt， and Bcl-2， and up-regulated protein level of Bax （P<0.01）. Compared with the model group， the 8 weeks of drug administration lowered the random blood glucose， increased the body mass and gastric emptying rate （P<0.05， P<0.01）， decreased the apoptotic index of smooth muscle cells in the gastric antrum （P<0.05， P<0.01）， up-regulated the protein levels of IGF-1， p-PI3K/PI3K， p-Akt/Akt， and Bcl-2， and down-regulated the protein level of Bax （P<0.05， P<0.01）. Compared with the mosapride citrate group，the administration of low-dose Hedysari Radix polysaccharide for 6 and 8 weeks lowered the random blood glucose and decreased the body mass （P<0.05， P<0.01），low and medium-dose Hedysari Radix polysaccharide decreased the gastric emptying rate and the apoptotic index of smooth muscle cells in the astragaloside low-dose group decreased （P<0.05）. The protein levels of IGF-1，p-PI3K/PI3K，p-Akt/Akt and Bcl-2（low dose）were down-regulated and the protein level of Bax was up-regulated by low doses of Hedysari Radix polysaccharide （P<0.05， P<0.01）. Compared with high-dose Hedysari Radix polysaccharide， low-dose Hedysari Radix polysaccharide elevated random blood glucose and reduced body mass after 6 and 8 weeks of administration （P<0.05， P<0.01）， and the low and medium doses decreased the gastric emptying rate， increased the apoptotic index of smooth muscle cells in the gastric antrum （P<0.05， P<0.01）， down-regulated the protein levels of IGF-1， p-PI3K/PI3K， p-Akt/Akt， and Bcl-2， and up-regulated the protein level of Bax （P<0.05， P<0.01）. Compared with the medium-dose group，the low-dose group of Hedysari Radix polysaccharide had lower body mass，lower gastric emptying rate in rats，higher apoptotic index of smooth muscle cells in gastric sinus tissue after 6 and 8 weeks of administration （P<0.05， P<0.01）， and lower protein expression of IGF-1，p-PI3K/PI3K，p-Akt/Akt. ConclusionHedysari Radix polysaccharide protects the smooth muscle cells in gastric antrum against apoptotic injury and promotes gastric motility by activating the IGF-1/PI3K/Akt signaling pathway， as manifested by the up-regulated expression of IGF-1， p-PI3K， p-Akt， and Bcl-2 and down-regulated expression of Bax.

Saponins are widely found in various Chinese medicines such as Ginseng Radix et Rhizoma， Notoginseng Radix et Rhizoma， and Bupleuri Radix. They possess multiple biological activities， including anti-inflammatory， antioxidant， antitumor， hepatoprotective， lipid-lowering， and hypoglycemic effects. They play an important role in the prevention and treatment of diseases such as acute lung injury， hyperlipidemia， and diabetic cardiovascular complications， and hold significant research potential and value. Metabolism-related fatty liver disease is a prevalent chronic liver disease characterized by excessive lipid accumulation in hepatocytes. According to the "multiple hit" theory， its occurrence is the result of systemic homeostasis disorder， influenced by abnormal lipid metabolism， oxidative stress， inflammation， insulin resistance， mitochondrial dysfunction， and intestinal microbiota. However， there is currently no effective treatment available in clinical practice. Recent studies have found that Chinese herbal saponins can alleviate metabolism-related fatty liver disease through various pathways， including regulating abnormal lipid metabolism， inhibiting inflammatory responses， alleviating oxidative stress， reducing insulin resistance， improving mitochondrial dysfunction， modulating intestinal flora， inhibiting hepatocyte programmed death， regulating liver autophagy， and correcting immune imbalances. Therefore， this review summarized the pharmacological effects and related mechanisms of Chinese herbal saponins in improving metabolism-related fatty liver disease in recent years， aiming to provide a theoretical reference for the clinical application and experimental research of Chinese herbal saponins in the prevention and treatment of metabolism-related fatty liver disease.

Objective:The obesity rate among middle-aged and young adults in China is increasing annually,and the incidence of cardiovascular diseases is becoming more prevalent in younger populations.However,it has not yet been reported whether obesity is associated with early vascular aging(EVA).This study aims to explore the correlation between obesity and EVA in middle-aged and young adult health check-up populations,providing a reference for the prevention of cardiovascular diseases. Methods:A total of 15 464 middle-aged and young adults aged 18-59 who completed brachial-ankle pulse wave velocity(baPWV)test in the Third Xiangya Hospital of Central South University from January to December 2020 were included.Among them,1 965 individuals with normal blood pressure and no cardiovascular risk factors were selected as the healthy population.The baPWV thresholds for determining EVA in each age group for males and females were calculated based on the baPWV values of the healthy population.The number and percentage of individuals meeting the EVA criteria in the middle-aged and young adult health check-up populations were statistically analyzed by age and gender.The differences in obesity indicators[visceral adiposity index(VAI),body mass index(BMI),waist circumference(WC)]between the EVA and non-EVA groups for males and females were compared.Using EVA as the dependent variable,VAI,BMI,and WC were included as independent variables in a Logistic model to analyze the correlation between each obesity indicator and EVA before and after adjusting for other influencing factors.Furthermore,the correlation between each obesity indicator and EVA in each age group was analyzed. Results:In the health check-up populations,the detection rate of EVA in different age groups was 1.65%-10.92%for males,and 1.16%-10.50%for females,the detection rate of EVA increased with age in both males and females.Except for the 40-<50 age group,the EVA detection rate was higher in males than in females in all other age groups.Regardless of gender,obesity indicators VAI,BMI,and WC were significantly higher in the EVA group than in the non-EVA group(all P<0.01).Before and after adjusting for other influencing factors,VAI and WC were both correlated with EVA(both P<0.05).BMI was a risk factor for EVA before adjusting for other influencing factors(P<0.01),but after adjustment,the correlation between BMI and EVA was not statistically significant(P=0.05).After adjusting for other influencing factors,the correlation between VAI and EVA was statistically significant in the 18-<40 and 50-<60 age groups(both P<0.05),while the correlation between BMI and WC with EVA was not statistically significant(both P>0.05).In the 40-<50 age group,the correlation between VAI and BMI with EVA was not statistically significant(both P>0.05),but the correlation between WC and EVA was statistically significant(P<0.01). Conclusion:VAI is closely related to the occurrence of EVA in middle-aged and young adults aged 18-<40 and 50-<60 years,while WC is closely related to the occurrence of EVA in those aged 40-<50 years.

Objective:To investigate the effects of intravascular hypothermia combined with early post-pyloric feeding on the neurological function and prognosis in patients with severe ischemic stroke, and to provide a theoretical basis for clinical decision-making on the optimal nutritional support strategy for patients with severe ischemic stroke during intravascular hypothermia treatment.Methods:This was a retrospective, non-randomized, controlled study. A total of 78 patients with first severe ischemic stroke who were admitted to the ICU of Neurology Department, Xuanwu Hospital, Capital Medical University from January 2018 to December 2021 were selected. General information and clinical data of the patients were collected and grouped according to intrvascular hypothermia combined with nutritional support. Patients were divided into early post-pyloric feeding group of 52 cases and early parenteral nutrition group of 26 cases. The neurological prognosis, disease prognosis, nutritional status and complications related to nutritional support of the two groups were retrospectively analyzed.Results:The Glasgow score at 30th day after intravascular hypothermia in the early postpyloric feeding group was (11.25 ± 4.92) points, which was higher than that in the early parenteral nutrition group (8.40 ± 5.53), and the difference was statistically significant ( t=-2.45, P<0.05). After treatment, the serum total protein and hemoglobin of early postpyloric feeding group were (59.56 ± 5.09) g/L and (131.06 ± 19.58) g/L, respectively, which were higher than those of early parenteral nutrition group (56.52 ± 7.94) g/L and (122.07 ± 17.72) g/L. The difference was statistically significant ( t=-2.03, -1.91, P<0.05). The clinical pulmonary infection score of the early postpyloric feeding group was (7.33 ± 0.96) points, which was lower than that of the early parenteral nutrition group (9.42 ± 2.11). The mechanical ventilation time and ICU stay time were (17.46 ± 10.47) days and (28.89 ± 12.59) days, respectively. Compared with the early parenteral nutrition group (25.77 ± 15.20) days and (37.07 ± 17.15) days, the differences were statistically significant ( t=3.28, 2.83, 2.52, all P<0.05). There were no significant differences in catheter-associated bloodstream infection and ICU hospitalization mortality between the two groups (both P>0.05). Conclusions:Intravascular hypothermia combined with early post-pyloric feeding can improve the nutritional status of patients with severe ischemic stroke, effectively control pulmonary infection, shorten mechanical ventilation and hospital stay, and promote neurological repair.
