ABSTRACT
Objective: To observe the effects of electroacupuncture (EA) of different frequencies on transmission function, electromyography, nitric oxide synthase (NOS) content and interstitial cells of Cajal (ICC) expression of colon in rat models with slow transit constipation (STC). Methods: Of the 50 healthy male Wistar rats, 10 were randomly selected as a normal group and fed with ordinary diet, and the remaining 40 rats were fed with the diet added with the compound diphenoxylate at a dose of 8 mg/(kg·bw) each day for continuous 120 d. The 40 successfully established STC rat models were randomly divided into a model group, a low-frequency EA group (2 Hz), a high-frequency EA group (100 Hz), and a variable-frequency EA group (2 Hz/100 Hz), with 10 rats in each group. Rats in the normal and the model groups were not given any treatment; the low-frequency EA and the high-frequency EA groups were given EA at Tianshu (ST 25), Zusanli (ST 36) and Zhigou (TE 6) with continuous wave at the designated frequency, and the variable-frequency EA group received sparse-dense wave (2 Hz/100 Hz) EA at the same acupoints, once a day for a total of 15 d. After treatment, the colonic transmission function, electromyography, NOS content and ICC expression (calculated by the difference in the area of the C-kit positive cells) of the rats in each group were measured. Results: For the colonic transmission function, compared with the normal group, the first black stool excretion durations of rats in the other groups were significantly prolonged (all P<0.05); compared with the model group, the first black stool excretion durations of rats in the three EA groups were significantly shortened (all P<0.05), which was significantly shorter in the variable-frequency EA group than in the low-frequency EA and high-frequency EA groups (both P<0.05). For the colonic electromyography, compared with the normal group, the amplitude was significantly increased and the frequency was accelerated in rats of the other groups (all P<0.05); compared with the model group, the amplitude was significantly reduced and the frequency was slowed down in the three EA groups (both P<0.05); compared with the low-frequency EA and the high-frequency EA groups, the amplitude was reduced and the frequency was significantly reduced in rats of the variable-frequency EA group (both P<0.05). Compared with the normal group, the colonic NOS contents were significantly increased in the other groups (all P<0.05); compared with the model group, the NOS contents were significantly reduced in the three EA groups (all P<0.05); compared with the low-frequency EA and the high-frequency EA groups, the content was significantly reduced in the variable-frequency EA group (all P<0.05). For the area of rat colonic C-kit-positive cells, compared with the normal group, the areas were significantly reduced in rats of other groups (all P<0.05); compared with the model group, the areas were increased significantly in the three EA groups (all P<0.05); compared with the low-frequency EA group, the area was increased significantly in the variable-frequency EA group (P<0.05). Conclusion: EA, especially EA at the 2 Hz/100 Hz variable-frequency, has a positive treatment effect on the STC model rats. It may improve rats' colonic function by regulating the electromyography, NOS content and ICC expression of colon.
ABSTRACT
In this study, the model of Propionibacterium acnes/lipopolysaccharide (P. acnes/LPS)-induced acute liver injury in mice was employed to investigate the protective effects of Fuzheng Yanggan Fomula (FYF) on acute liver injury. The effects of FYF on the contents of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and interleukin-1β (IL-1β) in the serum, and the levels of malondialdehyde (MDA), oxygen radical absorbance capacity (ORAC), and glutathione (GSH) were examined in the livers of mice treated with P. acnes/LPS; The protein expression levels of Nod-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), cysteinyl aspartate specific proteinase-1 (caspase-1), and IL-1β in liver tissues were detected by Western blot; Furthermore, hematoxylinendash-eosin (HE) staining, terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, and immunohistochemical assay were used to observe pathological changes, apoptosis index, and inflammation infiltration of the liver tissue sections. All animal welfare and experimental procedures were followed by the Animal Ethics Committee of Jinan University. We conclude that FYF could alleviate P. acnes/LPS induced pathological damage and inflammatory infiltration in the liver of mice. Meanwhile, FYF decreases the contents of ALT, AST, IL-1β, and MDA, increases the contents of ORAC and GSH, and downregulates the expression of caspase-1 and IL-1β proteins. Collectively, these findings suggested that FYF could alleviate P. acnes/LPS induced acute liver injury in mice by inhibiting the activation of NLRP3 inflammasome, which provides a theoretical basis and a new drug target for the prevention and treatment of liver injury.

The model of drug-induced liver injury (DILI) induced by acetaminophen (APAP) in mice was established to investigate the anti-oxidation and anti-ferroptosis mechanisms of Fuzheng Yanggan Mixture on DILI. C57BL/6 mice were randomly divided into five groups: control group, model group, positive group, and low and high-dose Fuzheng Yanggan Mixture groups (0.12, 0.24 g·kg⁻¹). Mice were intragastrically administration with Fuzheng Yanggan Mixture (0.12, 0.24 g·kg⁻¹) once per day for 21 consecutive days, and at the same time, mice were weighted every day. The mice were injected intraperitoneally with 600 mg·kg⁻¹ of APAP to establish a mouse model of acute DILI after 16 h from the last administration of Fuzheng Yanggan Mixture. After 6 h from APAP challenge, the experimental animals were weighted and sacrificed to collect blood and liver tissue samples. And then, the effect of Fuzheng Yanggan Mixture on liver weight and the liver weight ratio of mice were examined; the content of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the serum and the level of malondialdehyde (MDA), glutathione (GSH) and nicotinamide adenine dinucleotide phosphate (NADPH) in the liver tissue were measured. Prostaglandinendoperoxide synthase 2(ptgs2) mRNA level in liver tissues was detected by Q-PCR, and protein expression levels of SLC7A11 and GPX4 in liver tissues were detected by Western blot. Moreover, HE staining, immunohistochemical assay and TUNEL staining were used to observe pathological changes of the liver tissue sections. It is found that Fuzheng Yanggan Mixture could relieve APAP-induced liver enlargement and inhibit hepatic weight ratio increase. Compared with model group, the mice in Fuzheng Yanggan Mixture groups showed decreases in the content of ALT, AST and MDA, and increases in the content of GSH and NADPH. What is more, Fuzheng Yanggan Mixture could down-regulate ptgs2 mRNA level and up-regulate SLC7A11 and GPX4 protein levels. All of the results lead to a conclusion that Fuzheng Yanggan Mixture plays a protective effect on DILI in mice, which may be associated with the inhibition of ferroptosis.

ABSTRACT
Through computer-based technology and data mining method, with treatment in cases of bloodletting acupuncture therapy in collected literature as sample data, the association rule in data mining was applied. According to self-built database platform, the data was input, arranged and summarized, and eventually required data was acquired to perform the data mining of bleeding volume and method in blood-letting acupuncture therapy, which summarized its application rules and clinical values to provide better guide for clinical practice. There were 9 kinds of blood-letting tools in the literature, in which the frequency of three-edge needle was the highest, accounting for 84.4% (1239/1468). The bleeding volume was classified into six levels, in which less volume (less than 0.1 mL) had the highest frequency (401 times). According to the results of the data mining, blood-letting acupuncture therapy was widely applied in clinical practice of acupuncture, in which use of three-edge needle and less volume (less than 0.1 mL) of blood were the most common, however, there was no central tendency in general.
