MethodSixty female SLE patients who met the criteria in the First Affiliated Hospital of Anhui University of Chinese Medicine from May 2022 to May 2023 were selected and randomized into a control group and an observation group （30 cases in each group）. The control group was treated with prednisone acetate + hydroxychloroquine sulfate orally， and the observation group was additionally treated with Qihuang Jianpi Zishen granules. The treatment lasted for 8 weeks. The SLE disease activity （SLEDAI）， TCM syndrome score， erythrocyte sedimentation rate （ESR）， hypersensitive C-reactive protein （hs-CRP）， immune indexes ［immunoglobulin G （IgG）， C3， C4， CD4+， and CD8+］， interleukin （IL）-17， IL-23， interferon （IFN）-γ， 24 h urinary protein （24 h PRO）， serum creatinine （SCr）， and expression of proteins ［STAT3， phosphorylated （p）-STAT3， mTOR protein and STAT3，mTOR mRNA］ in the STAT3/mTOR signaling pathway were determined before and after treatment. In addition， the adverse reactions were recorded. ResultAfter 8 weeks of treatment， the total response rate in the observation group was 93.33% （28/30）， which was higher than that （70.00%， 21/30） in the control group （χ2=4.007， P<0.05）. After treatment， both groups showed declined SLEDAI， TCM syndrome score， ESR， hs-CRP， IgG， CD8+， IL-17， IL-23， IFN-γ， 24 h PRO， SCr， and expression of proteins in the STAT3/mTOR pathway （P<0.01） and elevated levels of C3， C4， and CD4+ （P<0.01）. Moreover， the observation group had lower SLEDAI， TCM syndrome score， ESR， hs-CRP， IgG， CD8+， IL-17， IL-23， IFN-γ， 24 h PRO， SCr， and expression of proteins in the STAT3/mTOR pathway （P<0.05， P<0.01） and higher levels of C3， C4， and CD4+ （P<0.05， P<0.01） than the control group after treatment. Neither group showed serious adverse reactions during the treatment period. ConclusionQihuang Jianpi Zishen Granules can ameliorate the inflammatory response， reduce the disease activity， and mitigate the kidney injury in SLE by inhibiting the STAT3/mTOR signaling pathway to regulate the immune function.
ABSTRACT
ObjectiveTo investigate the molecular mechanism by which Si Junzitang in intervening in the development of hepatocellular carcinoma （HCC） by regulating the O-linked β-N-acetylglucosamine modification （O-GlcNAcylation） of nuclear factor kappa-B （NF-κB） p65 in the paracancerous tissues. MethodThe orthotopic liver cancer mouse model was established. Twenty-four C57BL/6 mice were randomly divided into four groups： Normal group， model group， Si Junzitang low-dose group （10 g·kg-1）， and Si Junzitang high-dose group （25 g·kg-1）， with 6 mice in each group. The O-GlcNAcylation level and phosphorylation modification level of p65 in the paracancerous tissues were detected using Western blot. The O-GlcNAcylation of p65 was assessed using immunoprecipitation （IP）. The mRNA expression of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， transforming growth factor-β1 （TGF-β1）， vascular endothelial growth factor A （VEGFA）， matrix metalloproteinase-2 （MMP-2）， matrix metalloproteinase-9 （MMP-9） in the paracancerous tissues was detected using real-time quantitative polymerase chain reaction （Real-time PCR）. The tumor number， liver weight， locomotor activity， grip strength， and Qi status of the mice were observed and analyzed. ResultCompared with the normal group， the model group showed a significant decrease in O-GlcNAcylation in the paracancerous tissues （P<0.01）， a significant decrease in p65 O-GlcNAcylation （P<0.01）， a significant increase in p65 phosphorylation （P<0.01）， significantly elevated mRNA levels of cytokines IL-6， TNF-α， TGF-β1， VEGFA， MMP-2， and MMP-9 （P<0.01）， significantly increased liver weight （P<0.01）， significantly declined grip strength， number of grid crossings， and number of vertical stand-ups （P<0.01）， and significantly dwindled Qi status （P<0.01）. Compared with model group， the Si Junzitang low-dose and high-dose groups showed significantly increased levels of O-GlcNAcylation in the paracancerous tissues （P<0.05， P<0.01）， significantly upregulated p65 O-GlcNAcylation levels （P<0.05， P<0.01）， and significantly decreased p65 phosphorylation levels （P<0.01）. In the Si Junzitang low-dose group， the mRNA levels of IL-6， TGF-β1， and VEGFA significantly decreased （P<0.05， P<0.01）. In the Si Junzitang high-dose group， the mRNA levels of IL-6， TNF-α， TGF-β1， VEGFA， MMP-2， and MMP-9 significantly decreased （P<0.01）， the number of tumors larger than 3 mm in diameter significantly decreased （P<0.01）， and liver weight significantly decreased （P<0.05）. Additionally， grip strength， number of grid crossings， and number of vertical stand-ups significantly increased （P<0.05， P<0.01）， along with a significant increase in qi status （P<0.01）. ConclusionSi Junzitang can inhibit the progression of orthotopic HCC in mice， which may be achieved by increasing the O-GlcNAcylation level in the paracancerous tissues， enhancing the O-GlcNAcylation of p65， inhibiting the phosphorylation modification of p65， and ultimately suppressing the expression of downstream IL-6， TNF-α， TGF-β1， VEGFA， MMP-2， and MMP-9.
ABSTRACT
Yigongsan is derived from Xiaoer Yaozheng Zhijue written by QIAN Yi in the Northern Song dynasty， which is the No. 3 formula in the Catalogue of Ancient Famous Classical Formulas（The Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine（TCM） in September 2022， and it can be developed as a class 3.1 new TCM drug. By referring to ancient medical books and modern literature， this study conducted herbal textual research on Yigongsan from five aspects， including historical evolution， origin and processing， dosage conversion， usage and preparation methods， and functional application， then formed the key information table of this formula， in order to provide reference for the development of reference samples and preparations of Yigongsan. Based on the results of the study， it is recommended that Panax ginseng should be removed the basal part of stem（rhizoma）， Poria cocos should be removed the peel， Citrus reticulata should be cut into shreds and Glycyrrhiza uralensis should be used. According to 4.13 g/Qian（钱）， 1 g/slice for ginger， 3 g for each jujube and 300 mL/Zhan（盏）， the doses of Ginseng Radix， Poria， Atractylodis Macrocephalae Rhizoma， Glycyrrhizae Radix et Rhizoma， Citri Reticulatae Pericarpium， Zingiberis Rhizoma Recens， Jujubae Fructus were 1.652， 1.652， 1.652， 1.652， 1.652， 5， 6 g， and the total amount was 19.26 g. The decocting method was to crush the medicinal materials into fine powder with 50-80 mesh， add 300 mL of water and decoct to 210 mL for each dose， then remove the dregs and take it warmly. This formula was recorded in ancient books as the main treatment for the cold-deficiency of spleen and stomach， and Qi stagnation in children with vomiting and diarrhea and lack of appetite. It has been flexibly applied by later generations of physicians， and is often used to treat anorexia， inflammation of the digestive tract， diarrhea and other diseases in children.
ABSTRACT
ObjectiveTo establish and evaluate a mouse model of heart failure with Qi deficiency syndrome. MethodForty-four KM mice were randomly divided into sham operation group， model group， and modified Si Junzitang group （12.89 g·kg-1）. The model group and the modified Si Junzitang group underwent thoracic aortic constriction （TAC）， while the sham operation group only underwent suture without constriction. Echocardiography and pathological examination were used to assess the heart failure model and evaluate the pharmacological effects. Macroscopic characterization， microscopic biology， and formula identification were conducted to collect general signs， body weight， open-field behavior， grip strength， mitochondrial ultrastructure， and other macroscopic and microscopic characteristics of mice. Mitochondrial fission and fusion protein expression were measured to determine the syndrome type. ResultEight weeks after TAC， compared with the sham operation group， the model group showed a significant decrease in left ventricular ejection fraction （LVEF） （P<0.01）， and modified Si Junzitang improved LVEF in mice （P<0.05）. Hematoxylin-eosin （HE） staining of the heart showed inflammatory cell infiltration and thickening of blood vessel walls in the model group， which was significantly improved by modified Si Junzitang. After 6-8 weeks， compared with the sham operation group and the modified Si Junzitang group， the model group exhibited significant hair loss， hair yellowing， decreased activity， and depression. Moreover， compared with the sham operation group， the model group had a significantly lower increase in body weight （P<0.05）， while the modified Si Junzitang group showed a significant increase in body weight （P<0.05） compared with the model group. After 6-8 weeks， compared with the sham operation group， the model group showed a significant decrease in open-field distance and speed （P<0.05）， while the modified Si Junzitang group exhibited significantly improved open-field distance and speed in the 8th week （P<0.05）. After 6-8 weeks， compared with the sham operation group， the model group exhibited a significant decrease in maximum grip strength （P<0.05）， while the modified Si Junzitang group showed a significant increase in maximum grip strength 8 weeks after TAC （P<0.05）. Transmission electron microscopy of the gastrocnemius muscle showed uneven muscle tissue matrix， mitochondrial swelling， increased volume， matrix dissolution， ridge loss， and vacuolization in the model group， while modified Si Junzitang improved mitochondrial swelling， ridge fracture， and matrix vacuolization. Western blot analysis showed that the expression of the kinetic associated protein 1 （DRP1） in the gastrocnemius muscle of the model group significantly increased （P<0.01）， and the expression of mitochondrial fusion hormone 1 （MFN1） significantly decreased （P<0.05） as compared with those in the sham operation group. Furthermore， compared with the model group， the modified Si Junzitang group exhibited a significant decrease in the expression of DRP1 （P<0.05） and a significant increase in MFN1 expression （P<0.01）. ConclusionMice exhibited significant manifestations of qi deficiency syndrome 6-8 weeks after TAC， accompanied by abnormal mitochondrial morphology and function in the gastrocnemius muscle， which were significantly improved by modified Si Junzitang.
ABSTRACT
ObjectiveTo explore the mechanism of Si Junzitang in regulating the expression of NKG2A to affect the anti-colon cancer function of natural killer （NK） cells. MethodNK cells isolated from healthy honors were cultured and used to construct the three incubation models of NK cells， human colon cancer HCT116 cells， and NK cells + HCT116 cells （co-incubation）. real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was conducted to determine the mRNA levels of natural killer group 2 member A （NKG2A） and interleukin （IL）-15 in NK cells， as well as the mRNA level of histocompatibility leucocyte antigen E （HLA-E） in HCT116 cells. The secretion of IL-15 was detected by enzyme-linked immunosorbent assay （ELISA）. Methyl thiazolyl tetrazolium （MTT） assay was employed to determine the applicable concentration of IL-15 and test the effects of Si Junzitang and IL-15 on the activities of NK cells and the HCT116 cells in the co-incubation model. The effects of Si Junzitang and IL-15 on the mRNA levels of NKG2A in NK cells and HLA-E in HCT116 cells were detected by Real-time PCR. Monalizumab （M， anti-NKG2A mab） was used to block the NKG2A-HLA-E pathway in co-incubation model， and then the proliferation of HCT116 cells was detected by MTT assay. ResultThe interaction of NK cells and HCT116 cells up-regulated the mRNA levels of NKG2A in NK cells and HLA-E in HCT116 cells （P<0.05）， as well as the expression level and secretion of IL-15 （P<0.05）. Compared with the blank group， Si Junzitang and Si Junzitang + IL-15 promoted the proliferation and improved the anti-colon cancer function of NK cells （P<0.01）. Furthermore， they down-regulated the mRNA levels of NKG2A in NK cells and HLA-E in the HCT116 cells co-incubated with NK cells （P<0.01）. M and IL-15 + M inhibited the proliferation of HCT116 cells compared with the groups without M （P<0.01）. ConclusionThe interaction of NK cells and HCT116 cells can induce activation of NKG2A-HLA-E pathway to impair NK cell function. Si Junzitang can inhibit the activation of NKG2A-HLA-E pathway to restore the anti-colon cancer function of NK cells.

Method:Seventy-four SD male rats were randomly divided into normal group （12 rats） and model group （62 rats）. <italic>N</italic>-methyl-<italic>N'</italic>-nitro-<italic>N</italic>-nitrosoguanidine（MNNG）-ammonia compound method was used to establish GPL rat models， and at the 9<sup>th</sup> week， the model rats were randomly divided into model group， folic acid group（2.7 mg·kg<sup>-1</sup>）， modified Si Junzitang high， medium and low dose groups（12.6， 6.3， 3.15 g·kg<sup>-1</sup>）， with 12 rats in each group. After intragastric administration for 12 weeks， the general conditions of the rats were observed. Hematoxylin-eosin（HE）staining was used to observe the histopathological changes of gastric mucosa in rats， chemical colorimetry was used to detect the content of lactic acid in gastric mucosa； immunohistochemistry and real-time polymerase chain reaction（Real-time PCR）were used to detect MCT1， MCT4， CD147 protein and mRNA expression in gastric mucosal tissues. Result:Modified Si Junzitang significantly improved the pathological manifestations in GPL rats such as gastric mucosal epithelial gland structure， disorder of arrangement and cell atypia. Compared with the normal group， the lactic acid content of the gastric mucosa tissue in the model group increased significantly（<italic>P</italic><0.01）， and the protein and mRNA expressions of MCT1， MCT4， CD147 significantly increased（<italic>P</italic><0.05， <italic>P</italic><0.01）. Compared with the model group， the lactic acid content in each dose group of modified Si Junzitang was significantly reduced（<italic>P</italic><0.05， <italic>P</italic><0.01）， and the protein expression levels of MCT4 and CD147 were also significantly reduced in each dose group of modified Si Junzitang（<italic>P</italic><0.05， <italic>P</italic><0.01）. The mRNA expression of MCT4 was significantly reduced in the middle and high dose groups（<italic>P</italic><0.05， <italic>P</italic><0.01）， and the mRNA expression of CD147 was significantly reduced in the high dose group（<italic>P</italic><0.05）. Modified Si Junzitang showed no significant regulatory effect on MCT1. Conclusion:Modified Si Junzitang can significantly improve the abnormal histopathology of gastric mucosal epithelium in GPL model rats. Its mechanism may be related to down-regulating the overexpression of MCT4 and CD147， inhibiting lactic acid outflow， and improving the acidic microenvironment of gastric mucosal epithelium.

Hematoxylin-eosin (HE) staining and immunohistochemistry (IHC) were used to detect the distribution of blood vessels and the expression of vascular endothelial markers (CD31) in tumor-bearing mice. Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the mRNA expression levels of vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor 2 (VEGFR2) and tumor necrosis factor-α (TNF-α) in tumor tissue. Result:The inhibition rates of modified Sijunzi Tang in low-dose group (ig, 11.83 mg·kg-1·d-1), middle-dose group (ig, 23.66 mg·kg-1·d-1) and high-dose group (ig, 47.32 mg·kg-1·d-1) were 29.97%, 59.80%and 82.34%, respectively. Compared with the model group, the average tumor weight was lower in middle and high-dose groups, with statistically significant differences (PPPα in middle and high-dose modified Si Junzitang groups were lower than those in the model group (PConclusion:Modified Si Junzitang can inhibit the tumor growth of H22 tumor-bearing mice and the angiogenesis of transplanted tumors, which may be related to the reduction of TNF-α, VEGF and VEGFR2 expression levels.
