The mild-natured and bitter-flavored traditional Chinese medicines (MB-TCMs) are an important class of TCMs that have been widely used in clinical practice and recognized as safe long-term treatments for chronic diseases. However, as an important class of TCMs, the panorama of pharmacological effects and the mechanisms of MB-TCMs have not been systemically reviewed. Compelling studies have shown that gut microbiota can mediate the therapeutic activity of TCMs and help to elucidate the core principles of TCM medicinal theory. In this systematic review, we found that MB-TCMs commonly participated in the modulation of metabolic syndrome, intestinal inflammation, nervous system disease and cardiovascular system disease in association with promoting the growth of beneficial bacteria Bacteroides, Akkermansia, Lactobacillus, Bifidobacterium, Roseburia as well as inhibiting the proliferation of harmful bacteria Helicobacter, Enterococcus, Desulfovibrio and Escherichia-Shigella. These alterations, correspondingly, enhance the generation of protective metabolites, mainly including short-chain fatty acids (SCFAs), bile acid (BAs), 5-hydroxytryptamine (5-HT), indole and gamma-aminobutyric acid (GABA), and inhibit the generation of harmful metabolites, such as proinflammatory factors trimethylamine oxide (TAMO) and lipopolysaccharide (LPS), to further exert multiplicative effects for the maintenance of human health through several different signaling pathways. Altogether, this present review has attempted to comprehensively summarize the relationship between MB-TCMs and gut microbiota by establishing the TCMs-gut microbiota-metabolite-signaling pathway-diseases axis, which may provide new insight into the study of TCM medicinal theories and their clinical applications.

ObjectiveTo establish a polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for rapid distinguishing Periplocae Cortex from Acanthopanacis Cortex and Lycii Cortex, so as to avoid the influence of genetic confusion on drug safety. MethodThe DSS-tagged sequences of Periplocae Cortex were obtained from the Chloroplast Genome Information Resource (CGIR) and analyzed to find the enzymatic cleavage sites that were different from those of Acanthopanacis Cortex and Lycii Cortex. The specific enzymatic cleavage site, Cla I, of Periplocae Cortex was selected, on the basis of which the primers for PCR-RFLP were designed. Furthermore, the factors such as annealing temperature, number of cycles, Taq enzyme, PCR instruments, and enzymatic treatment time that may influence PCR-RFLP were studied. The established PCR-RFLP method was applied to the identification of Periplocae Cortex, Acanthopanacis Cortex, and Lycii Cortex samples produced in different regions. ResultThe PCR-RFLP at the annealing temperature of 59 ℃ and with 40 cycles showed clear bands of the samples. When the enzyme digestion time was 30 min. The reaction produced the target bands at about 140 bp and 290 bp for both Periplocae Cortex and its original plant and only a band at about 430 bp for Acanthopanacis Cortex, Lycii Cortex, and their original plants. The method can accurately distinguish Periplocae Cortex from its confounders Acanthopanacis Cortex and Lycii Cortex. ConclusionThe PCR-RFLP method for distinguishing Periplocae Cortex from Acanthopanacis Cortex and Lycii Cortex was established. It has high stability, sensitivity, and applicability, providing a reference for the quality control of Periplocae Cortex, Acanthopanacis Cortex, and Lycii Cortex.

Objective:
To explore the prevalence and related factors of overweight, obesity and hypertension comorbidities among children and adolescents in Ningxia, so as to provide a scientific basis for effective early health intervention in children and adolescents.
Methods:
From September 2021 to June 2022, a total of 4 577 students aged 9-16 were selected from Jinfeng District of Yinchuan City, Shapotou District of Zhongwei City, Yanchi County of Wuzhong City and Pingluo County of Shizuishan City in Ningxia by multi stage cluster random sampling method for questionnaire survey and physical measurement. The influencing factors of overweight, obesity and hypertension comorbidities in children and adolescents were investigated by Chi square test and multivariate unconditioned Logistic regression analysis with weighted complex sampling design.
Results:
The prevalence of overweight and obesity among primary and secondary school students in Ningxia was 22.87%, the prevalence of hypertension was 1.30%, and the comorbity rate of overweight, obesity and hypertension was 1.07%. Multivariate Logistic regression analysis showed that students aged 13-16 ( OR =15.66,95% CI =3.84-63.96, P <0.05) were more likely to suffer from overweight, obesity and hypertension than students aged 9-12. The students of insufficient sleep duration ( OR =5.47, 95% CI =1.73-17.33, P <0.05) had higher levels of overweight, obesity and hypertension comorbidities than those of adequate sleep duration. Students who had breakfast 1 to 7 times a week ( OR =0.08, 95% CI =0.02-0.37) had lower incidence than those who had breakfast once a week ( P <0.05).
Conclusions
Age, sleep time and breakfast frequency are all related factors of overweight, obesity and hypertension co morbidity among primary and secondary school students in Ningxia. Close attention should be paid to students aged 9-12 years with insufficient sleep time and fasting in the morning, and carry out scientific education and prevention and control interventions should be carried out.

ELISA was used to detect the serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β(IL-1β) and immunohistochemistry was used to detect the levels of amyloid β-protein (Aβ), glial fibrillary acidic protein(GFAP) and NF-κB in hippocampal tissue.Western blot was used to detect the expression levels of TLR4, myeloid differentiation primary response gene 88(MyD88), and phosphorylated NF-κB(p-NF-κB) proteins in hippocampal tissue.The SPSS 20.0 software was used for data analysis. Multiple group comparisons were conducted by repeated measure ANOVA or one-way ANOVA.Results:The results of repeated measure ANOVA showed that as for the escape latency of the 6 groups of mice, the interaction effect between time and group was significant ( Finteraction=117.219, P<0.001). The escape latencies of mice in the 6 groups on the 5th day were all lower than those on the 1st day (all P<0.05). The escape latencies of mice in the ibuprofen group and the medium-dose and high-dose groups of Liuwei Dihuang Wan were lower than that in the model group from 1st day to 5th day(all P<0.05). On the 3rd to 5th day, the escape latencies of mice in the medium-dose and high-dose groups of Liuwei Dihuang Wan were lower than those in the low-dose group of Liuwei Dihuang Wan (all P<0.05). There were statistically significant differences in the percentage of residence time in the platform quadrant and the numbers of crossing platform among the 6 groups of mice ( F=5.451, 4.824, both P<0.05). The percentage of residence time in the platform quadrant (50.77±5.49)%, (54.39±5.71)%, (51.98±6.12)%), and the numbers of crossing platform((5.9±1.1) times, (6.0±1.3) times, (5.1±0.8) times) in the high-dose and medium-dose groups of Liuwei Dihuang Wan and the ibuprofen group were all higher than those in the model group ((27.32±3.22)%, (2.2±1.0) times )(all P<0.05). The immunohistochemical results showed that there were statistically significant differences in the integrated optical density values of Aβ, GFAP and NF-κB in the hippocampal tissues of 6 groups of mice ( F=57.52, 45.37, 79.10, all P<0.05). The integrated optical density values of Aβ, GFAP and NF-κB in the high-dose and medium-dose groups of Liuwei Dihuang Wan and the ibuprofen group were all lower than those in the model group (all P<0.05). And the integrated optical density values of Aβ, GFAP, and NF-κB in the high-dose and medium-dose groups of Liuwei Dihuang Wan were all lower than those in the low-dose group of Liuwei Dihuang Wan (all P<0.05). There were statistically significant differences in the levels of serum TNF-α and IL-1β detected by ELISA ( F=3.996, 6.395, both P<0.05) and the proteins levels of TLR4, MyD88, and p-NF-κB in hippocampal tissue detected by Western blot among the 6 groups( F=15.710, 3.522, 4.119, all P<0.05). The serum TNF-α and IL-1β levels in the high-dose and medium-dose groups of Liuwei Dihuang Wan and ibuprofen group were all lower than those in the model group (all P<0.05). The serum TNF-α ((18.90±2.33) ng/L, (21.56±2.49) ng/L) and IL-1β ((5.88±0.80) ng/L, (6.75±0.83) ng/L) levels in the high-dose and medium-dose groups of Liuwei Dihuang Wan were lower than those in the low-dose group ((30.77±2.89) ng/L, (9.11±1.27) ng/L) (all P<0.05). The protein expression levels of TLR4, MyD88, and p-NF-κB in the hippocampus of the high-dose and medium-dose groups of Liuwei Dihuang Wan and ibuprofen group were lower than those of the model group (all P<0.05). The protein expression levels of TLR4 ((0.254±0.091), (0.318±0.122)), MyD88 ((0.229±0.077), (0.386±0.119)), and p-NF-κB ((0.412±0.188), (0.358±0.119)) in the hippocampus of the high-dose and medium-dose groups of Liuwei Dihuang Wan were lower than those of the low-dose group ((0.617±0.172), (0.672±0.166), (0.799±0.227)) (all P<0.05). Conclusion:Liuwei Dihuang Wan can significantly alleviate learning and memory impairment in Alzheimer's disease model mice, possibly by inhibiting TLR4/NF-κB signal pathway, reducing TNF-α and IL-1β expression, thereby alleviate central immune inflammatory response and exert anti Alzheimer's disease effects.
