ObjectiveTo investigate the therapeutic effect of rhubarb decoction （RD） retention enema on a rat model of minimal hepatic encephalopathy （MHE） and its mechanism of action based on bile acid （BA） metabolomics. MethodsA total of 55 male Sprague－Dawley rats were randomly divided into blank group （NC group with 10 rats）， hepatic encephalopathy group （HE group with 15 rats）， MHE group with 15 rats， and MHE+rhubarb decoction treatment group （MHEY group with 15 rats）. Intraperitoneal injection of carbon tetrachloride （CCl4） and thioacetamide （TAA） was performed to establish a rat model of MHE or HE， and the rats were sacrificed after 2 weeks of administration. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， total bilirubin （TBil）， and total bile acid （TBA） and the concentration of blood ammonia were measured； the colonic contents were collected to measure pH value； liver and brain tissue samples were collected， and HE staining was used to observe the histopathological changes of the liver； the bile was collected， and liquid chromatography－mass spectrometry was used to perform BA－targeted metabolomics analysis. Continuous data were expressed as mean±standard deviation； a one－way analysis of variance was used for comparison between multiple groups， and the least significant difference t－test was used for further comparison between two groups. ResultsCompared with the NC group， the HE group and the MHE group had a significant increase in searching platform latency （after modelling and after administration） and a significant reduction in the number of platform crossings （all P<0.05）； compared with the MHE group， the MHEY group had a significant reduction in searching platform latency （after administration） and a significant increase in the number of platform crossings， and the HE group had a significant increase in searching platform latency and a significant reduction in the number of platform crossings （all P<0.05）. Compared with the NC group， the HE group and the MHE group had significant increases in AST， ALT， ALP， TBil， TBA， blood ammonia， and colon pH value （all P<0.05）； compared with the MHE group， the MHEY group had significant reductions in AST， ALT， ALP， TBil， TBA， blood ammonia， and colon pH value （all P<0.05）， and the HE group had significant increases in AST， ALT， ALP， TBil， TBA， blood ammonia， and colon pH value （all P<0.05）. The MHE group had significantly lower TBA， primary BA， and secondary BA than the NC group （all P<0.05）； compared with the MHE group， the HE group had significantly lower TBA and primary BA （all P<0.05）， and the MHEY group had significantly higher TBA and primary BA （all P<0.05）. Compared with the NC group， the MHE group had significant reductions in GCDCA， GUDCA， GHDCA， TCDCA， TUDCA， GLCA， and TLCA （all P<0.05） and significant increases in γ－MCA， THCA， 7－KDCA， AlloLCA， and α－MCA （all P<0.05）， and compared with the MHE group， the MHEY group had significant increases in THDCA， TMCA， TCDCA， TUDCA， and TLCA （all P<0.05）. ConclusionRD retention enema can improve liver injury and cognitive function in a rat model of MHE induced by CCl4 and TAA by regulating the enterohepatic circulation of BA， possibly by increasing the synthesis of taurine－binding BA.

Analysis of the status and risk factors of in stent restenosis in patients with acute myocardial infarction and diabetes mellitus one year after percutaneous coronary intervention / 中国医师杂志

Objective:To analyze the status of in stent restenosis (ISR) in patients with acute myocardial infarction (AMI) and diabetes mellitus (DM) one year after percutaneous coronary intervention (PCI), and explore the risk factors.Methods:From December 2019 to December 2020, 158 patients with AMI and DM who were treated by PCI in Qionghai Hospital of Traditional Chinese Medicine and the First Affiliated Hospital of Hainan Medical College were selected. They were followed up for one year after surgery to calculate the incidence of ISR. The patients were divided into ISR group and non ISR group according to whether ISR occurred. The difference of clinical data between the two groups was compared. Logistic regression was used to analyze the risk factors for the occurrence of ISR in AMI patients with DM 1 year after PCI.Results:55 patients were followed up for 1 year, and the incidence of ISR was 34.81% (55/158). There were significant difference between ISR group and non ISR group in hypertension history, old myocardial infarction history, smoking, exercise ratio, preoperative low density lipoprotein cholesterol (LDL-C), total bilirubin (TBIL), blood uric acid (UA), plasma fibrinogen (FIB), glycosylated hemoglobin (HbA 1c) levels, coronary artery lesion number, stenosis degree, stent length, stent diameter (all P<0.05). Multivariate logistic regression analysis showed that hypertension history, smoking, LDL-C, FIB, HbA 1c and stent length were independent risk factors for ISR in AMI patients with DM after PCI, and exercise and appropriate increase of stent diameter were protective factors (all P<0.05). Conclusions:The incidence of ISR in AMI patients with DM at 1 year after PCI is relatively high, and its occurrence is related to many factors. In order to reduce the risk of ISR after PCI, we should encourage smoking cessation, exercise, strengthen the monitoring of biochemical indicators, and appropriately increase the diameter of stent during PCI.

The commonly used food combination of children with spleen deficiency and accumulation of stagnation was "lentil bean-yam-japonica rice" and "millet-yam".Conclusions:Traditional Chinese medicine diet prescription for the treatment of children's accumulation of stagnation pay attention to harmony and regulation, sweet and slow tonifying, emphasizing the adjustment of the spleen and stomach, taking into account the regulation of lung, following the "eliminating and supplementing both, according to the cause of treatment" rule, advocate syndrome differentiation of food.

Mining intrinsic information of convalescent patients after suffering coronavirus disease 2019 in Wuhan.

OBJECTIVE: To summarize the potential characteristics of convalescent patients with coronavirus disease 2019 (COVID-19) in China based on emerging clinical tongue data and guide the treatment and recovery of COVID-19 patients from the perspective of Traditional Chinese Medicine tongue diagnosis. METHODS: In this study, we developed and validated radiomics-based and lab-based methods as a novel approach to provide individualized pretreatment evaluation by analyzing different features to mine the orderliness behind tongue data of convalescent patients. In addition, this study analyzed the tongue features of convalescent patients from clinical tongue qualitative values, including thick and thin, fur, peeling, fat and lean, tooth marks and cracked, and greasy and putrid fur. RESULTS: We included 2164 tongue images in total (34% from day 0, 35.4% from day 14 and 30.6% from day 28) from convalescent patients. The significance results are shown as follows. Firstly, as the recovery time prolongs, the L average values of tongue and coat decrease from 60.21 to 57.18 and from 60.06 to 57.03 respectively. Secondly, the decrease of abnormality rate of tongue coat, included greasy tongue fur, putrid fur, teeth-mark, thick-thin fur, are of significant statistical difference ( < 0.05). Thirdly, the average value of gray-level co-occurrence matrices increases from 0.173 to 0.194, the average value of entropy increases from 0.606 to 0.665, the average value of inverse difference normalized decrease from 0.981 to 0.979, and the average value of dissimilarity decrease from 0.1576 to 0.1828. The details of other radiomics features are describe in results section. CONCLUSIONS: Our experiment shows that patients in different recovery periods have a relationship with quantitative values of tongue images, including L color space of the tongue and coat radiomics features analysis. This relationship can help clinical doctors master the recovery and health of patients as soon as possible and improve their understanding of the potential mechanisms underlying the dynamic changes and mechanisms underlying COVID-19.

Bie Jia Jian pill enhances the amelioration of bone mesenchymal stem cells on hepatocellular carcinoma progression.

BACKGROUND: The therapeutic efficiency of Traditional Chinese Medicine (TCM) in suppressing the recurrence and metastasis of hepatocellular carcinoma (HCC) has been well proved. OBJECTIVE: The aim of this study is to investigate the role of Bie Jia Jian pill (BJJP) combined with bone mesenchymal stem cells (BMSCs) in HCC progression. METHODS: Flow cytometry was used to identify BMSCs isolated from BALB/c mice. The expressions of biomarkers and apoptosis rate of cancer stem cells (CSCs) enriched from Huh7 cells were also measured. The osteogenic differentiation and adipogenic differentiation ability of isolated BMSCs was determined by oil red O staining and Alizarin Red Staining. CSCs were used to establish the orthotopic HCC model. Histological changes in the liver tissues were examined by hematoxylin-eosin (H&E) staining and Van Gieson (VG) staining. The cell apoptotic rate in the cancer tissues was detected by TUNEL staining. The cell proliferation antigen Ki67 in the cancer tissues were detected by immunofluorescence assay and PCR, respectively. The levels of CSCs cellular surface markers (CD24, CD133 and EpCAM) and Wnt/ß-catenin signal pathway related proteins were detected by PCR and western blot. RESULTS: Treatment of BJJP or BMSCs both improved the morphology induced by HCC and suppressed the differentiation ability of CSCs, as evidenced by down-regulated expressions of CD24, CD133, EpCAM and Ki67. The protective effect of BJJP or BMSCs in cancer tissues can be enhanced by the combination of BJJP and BMSCs. In addition to that, BJJP or BMSCs alone was found to increase the expression of miR-140 and promote cell apoptosis in CSCs, while down-regulation of miR-140 partially reversed the protective effect of BMSCs or BJJP + BMSCs on cancer tissues. BJJP + BMSCs treatment together also can down-regulate the expressions of Wnt3a and ß-catenin. CONCLUSIONS: These results proved the inhibitory role of BJJP + BMSCs in HCC development through regulating miR-140 and Wnt/ß-catenin signal pathway.

Bie Jia Jian Pill Combined with Bone Mesenchymal Stem Cells Regulates microRNA-140 to Suppress Hepatocellular Carcinoma Stem Cells.

BACKGROUND AND OBJECTIVES: Cancer stem cells (CSCs) with tumorigenic potential are reported as the crucial factors of hepatocellular carcinoma (HCC) recurrence and therapy resistance. Bone mesenchymal stem cells (BMSCs) are documented to play an important role in the protection of hepatocytes. Bie Jia Jian pill (BJJP), a Traditional Chinese Medicine, has been used to treat liver fibrosis and liver cancer. This study aimed to explore the potential role of combined use of BJJP with BMSCs in HCC cell lines. METHODS AND RESULTS: Flow cytometry was used to identify BMSCs isolated from BALB/c mice and CSCs enriched from Huh7 cells by measuring CD24, CD133, CD44, CD73, CD105, CD166, CD29, CD14 and CD34. Differentiation potential of BMSCs was also determined. Cell viability and proliferation ability of CSCs were determined by CCK-8 assay and clone formation assay. The expressions of CSCs biomarkers and Wnt/ß-catenin signal pathway related proteins were determined by PCR and western blot. TOP-Flash/FOP-Flash luciferase assay was applied to measure the activity of ß-catenin/TCF. Compared with untreated CSCs, BJJP or BMSCs treatment alone on CSCs lead to increased miR-140 expression and cell apoptosis, as well as decreased expressions of CD24, CD133, EpCAM and cell viability. Downregualted expressions of Wnt/ß-catenin signal pathway related proteins, Wnt3a and ß-catenin were found in response to BJJP or BMSCs treatment alone. The combination of BJJP＋BMSCs treatment on CSCs could further enhance the suppressive effect on CSCs. Down-regulation of miR-140 in CSCs partially blocked the effects of BMSCs or BMSCs＋BJJP on the expressions of Wnt3a and ß-catenin as well as the cell viability and apoptosis of CSCs. Reversed expression pattern was found in CSCs transfected with miR-140 overexpression. CONCLUSIONS: Taken together, we demonstrate that BJJP＋BMSCs together could further enhance the suppressive effect on CSCs through regulating miR-140 and suppressing Wnt/ß-catenin signal pathway. This study demonstrated the potential of BJJP＋BMSCs in therapeutic treatment of HCC.
