In order to explore the possibility of Jerusalem artichoke stalk for bioenergy conversion, we analyzed the main composition of whole stalk, pitch, and core of the stalk. Meanwhile, these parts were pretreated with different NaOH concentrations at 121 degrees C. Afterwards, enzymatic hydrolysis was performed to evaluate the pretreatment efficiency. Jerusalem artichoke stalk was characterized by relatively high lignin content (32.0%) compared with traditional crop stalks. The total carbohydrate content was close to that of crop stalks, but with higher cellulose content (40.5%) and lower hemicellulose (19.6%) than those of traditional crop stalks. After pretreatment, the lignin content in the whole stalk, pitch, and core decreased by 13.1%-13.4%, 8.3%-13.5%, and 19.9%-27.2%, respectively, compared with the unpretreated substrates. The hemicellulose content in the whole stalk, pitch, and core decreased 87.8%-96.9%, 87.6%-95.0%, and 74.0%-90.2%, respectively. Correspondingly, the cellulose content in the pretreated whole stalk, pitch, and core increased by 56.5%-60.2%, 52.2%-55.4%, and 62.7%-73.2%, respectively. Moreover, increase of NaOH concentration for pretreatment could improve the enzymatic hydrolysis of the whole stalk and pitch by 2.3-2.6 folds and 10.3-18.5 folds, respectively. The hydrolysis of pretreated stalk core decreased significantly as 2.0 mol/L NaOH was employed, although the increased NaOH concentration can also improve its hydrolysis performance. Based on these results, hot-NaOH can be regarded as an option for Jerusalem artichoke stalk pretreatment. Increasing NaOH concentration was beneficial to hemicellulose and lignin removal, and consequently improved sugar conversion. However, the potential decrease of sugar conversion of the pretreated core by higher NaOH concentration suggested further optimization on the pretreatment conditions should be performed.

Objective:
To explore the effectiveness of healthy school canteen intervention on nutritional literacy, food consumption, as well as attitude towards school canteen.
Methods:
A primary school in Taizhou City was selected as the intervention school, and another comparable primary school was selected as the control one. A total of 320 students (163 in the intervention group and 157 in the control group) received a comprehensive intervention based on the construction of a healthy school canteen in the school,incluling healthy dining environment,food impravement,chef training,nutrition and health education, while the control group did not receive any intervention. Questionnaires survey was administered to both groups before and after the intervention.
Results:
Before the intervention, no significant differences were found in the total scores of skills and nutrition literacy, frequency of food intake, behaviors and attitudes related to canteen construction between the two groups( P >0.05). Daily intake of vegetables, dairy products, fish/poultry/eggs/lean meat increased by 19.63, 15.95 and 19.63 percentage point respectively ( χ 2=15.25,9.14,13.93, P <0.01). The proportion of students reporting have read related intervention materials in the intervention group(95.71%) was higher than the control group(84.71%) ( χ 2= 11.04, P < 0.01 ). The students in favor of low salt, low oil and low sugar dishes in the intervention group (74.85%) was higher than in the control group(48.41%) ( χ 2=23.73, P <0.01).
Conclusion
Based on the comprehensive intervention of nutrition and health canteens can improve students nutrition literacy and dietary structure. It is recommended to adopt the form of "home school linkage" to carry out the construction of large sample, multi regional and long term nutrition and health canteens.

Cardiovascular diseases are the most important diseases that endanger national health, and its development process is complex and diverse. Various cardiovascular diseases caused by obesity, such as hyperlipidemia, hyperglycemia and atherosclerosis, are interrelated and interacted each other. Diet, as the main means of prevention and treatment, plays an important role in the occurrence and development of cardiovascular disease. Mori Fructus is one of the first ingredients that are listed in medicinal and edible food. With a wide range of applications in daily life, it contains polysaccharides(polysaccharide, APS), anthocyanins(anthocyanin, LCRA), flavonoids and other bioactive ingredients. With a wide range of antioxidant, anti-aging, hypoglycemic and hypolipidemic activities, these materials exert effects in alleviating diabetes, hyperglycemia, hyperlipidemia and other cardiovascular diseases. In this paper, we retrieved such databases as PubMed, Web of science, CNKI, VTTMS, Wan Fang, and collected literatures about the effect of single administration of mulberry on cardiovascular diseases in the past 15 years, with "mulberry and cardiovascular disease" as the key word, and summarized the latest progress. The results of many experimental studies have showed that different forms of mulberry can significantly alleviate obesity, diabetes, atherosclerosis, hyperlipidemia and hypertension, suggesting that the scope of action of Mori Fructus covers different pathological stages of cardiovascular diseases. This paper systematically analyzes and summarizes the application forms, efficacy and the existing problems of these experiments, and provides study thinking and development direction for the utilization and new product design of Mori Fructus-related products in the treatment of cardiovascular diseases.

Objective :
To explore the effect of esketamine on anxiety-depressive-like behavior in mice and its rela- tionship with inflammation.
Methods :
SPF grade healthy adult male C57BL/6J mice,weighing 20 -24 g,were used in the exprement.The random number table method was used to divide into 5 groups (n = 8) : control group ( Con group) ,esketamine group (ESK group) ,model group ( LPS group) ,model + esketamine prevention group (LPS + ESK1 group) and model + esketamine treatment group ( LPS + ESK2 group) .An inflammation-induced anxiety-depression model was prepared by intraperitoneal injection of LPS 0. 83 mg / kg.The ESK group was injec- ted with esketamine 10 mg / kg ; LPS group was injected with LPS 0. 83 mg / kg ; LPS + ESK1 group was injected with LPS 0. 83 mg / kg before 24 hours intraperitoneal injection of esketamine 10 mg / kg ; and the LPS + ESK2 group was injected with LPS 0. 83 mg / kg and 30 minutes later with esketamine 10 mg / kg.24 h after intraperitoneal injec- tion of LPS,the anxiety-depression-like behaviors of mice were measured using behavioral experiments.At the end of behavioral experiments,the spleen was taken immediately ; hippocampal tissues were taken and enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of interleukin-1 β (IL-1 β) ,tumor necrosis factor al- pha (TNF-α) and interleukin 6 (IL-6) and neuronal pathological changes in hippocampal tissues were observed by HE staining.
Results :
Compared with the Con group,mice in the LPS group showed increased anxiety and depres- sion-like behavior (P<0. 05) ,increased spleen weight / body weight (P <0. 05 ) ,increased hippocampal tissue concentrations of IL-1 β , TNF-α and IL-6 (P<0. 05) ,and increased neuronal degeneration necrosis,there was no statistically significant difference in these indicators in the ESK group compared with the Con group.Compared with the LPS group,mice in the LPS + ESK1 and LPS + ESK2 groups showed reduced anxiety-depression-like behavior (P<0. 05) ,decreased splenic weight / body weight (P <0. 05) ,hippocampal tissue IL-1 β , TNF-α , IL- 6 con- centrations were reduced (P<0. 05) ,and neuronal degeneration necrosis was reduced.Compared with the LPS + ESK1 group,the LPS + ESK2 group showed an increase in the distance travelled in the central area of the open field experiment and the distance into the open arm of the elevated cross maze experiment (P<0. 05) ,a decrease in IL-6 and TNF-α concentrations (P<0. 05) ,and a reduction in the degree of neuronal damage.
Conclusion
Esketamine ameliorates LPS-induced anxiety-depression-like behavior and neuronal damage in mice by a mechanism that may be related to reduced inflammation.

Acta Universitatis Medicinalis Anhui 2023;58(10):1719-1723,1730
Objective :
To study the protective effect and mechanism of remimazolam on cognitive function in septic mice.
Results :
In the LPS group,the number of platform crossing times,the percentage of staying time in the first quadrant,GSH level and SOD activity significantly decreased,and TNF-α, IL-1 β and MDA levels significantly increased.In addition,the arrangement of neurons in CA1 area of hippocampus was disturbed ; cytoplasmic staining was deepened ; and the nucleus was solidly stained.Comparing RM10 ,RM15 and RM20 groups with the LPS group,the number of platform crossing times,the sta- ying time in the first quadrant,GSH level and SOD activity increased,and the levels of TNF-α, IL-1 β and MDA decreased.And the results of hippocampal staining showed a decrease in degenerated neuronal cells.When it came to the comparision in the groups with different doses of remimazolam injection,septic mice in the RM20 group showed less improvement in cognitive dysfunction and inflammatory oxidative stress than the RM10 and RM15 groups.
Conclusion
Remimazolam has a protective effect on cognitive dysfunction in septic mice,and its mechanism may be related to its binding of translocator protein ( TSPO) to inhibit macrophage polarization and thus reduce neuroinflammation and oxidative stress damage.It also reflects that dose of 10 mg / kg and 15 mg / kg has more significant protective effect than that of 20 mg / kg.
