Historical Evolution and Modern Research Progress of Processing of Notoginseng Radix et Rhizoma / 中国实验方剂学杂志

By reviewing the relevant literature of ancient herbal works and modern codices， this paper sorted out the historical evolution and developmental venation of processing of Notoginseng Radix et Rhizoma. On this basis， the modern research of processed products of Notoginseng Radix et Rhizoma was used as the breakthrough point to analyze the literature in terms of processing technology， chemical composition changes and changes in pharmacological effects before and after processing. According to the research status of processing of Notoginseng Radix et Rhizoma， some existing problems were analyzed in this paper， such as not many ancient processing methods used in modern time， lack of standardized research on processing technology. And saponins， polysaccharides， amino acids， flavonoids and other chemical components in Notoginseng Radix et Rhizoma may change to different degrees before and after processing， which was the main reason for the difference of efficacy before and after processing. However， the current research on the pharmacological effects of Notoginseng Radix et Rhizoma mainly focuses on raw products， resulting in a lack of in-depth research on the transformation mechanism of Notoginseng Radix et Rhizoma in processing difference， and the scientific connotation of "Shengxiao Shubu" has not been clearly elaborated， which is not conducive to the standardized clinical use of drugs. Therefore， it is necessary to further analyze the material basis of Notoginseng Radix et Rhizoma and its processed products， and to explore the change rule of chemical components before and after processing and its correlation with pharmacodynamic activity， so as to clarify the processing mechanism for providing scientific basis for its standardized processing， quality control and clinical rational use.

Analysis on the influencing factors for re-positive nucleic acid test result in discharged COVID-19 patients in Chengdu / 中国胸心血管外科临床杂志

@#Objective    To analyze the influencing factors for re-positive nucleic acid test in discharged corona-virus disease 2019 (COVID-19) patients in Chengdu, Sichuan Province, and to provide data support for the epidemics prevention and control. Methods    The clinical data of 660 discharged COVID-19 patients from January 23, 2020 to February 28, 2021 in our center were retrospectively analyzed. The patients were divided into two groups according to the reexamination of virus nucleic acid, including a negative group [549 patients, including 428 males and 121 females with a median age of 33.0 (28.0, 48.0) years] and a positive group [111 patients, including 76 males and 35 females with a median age of 39.0 (28.0, 51.0) years]. The clinical data of the two groups were compared. Results     The re-positive rate of the discharged patients was 16.82%. Univariate analysis showed that the re-positive rate of females was higher than that of males (χ2=4.608, P=0.032). The re-positive rate of confirmed patients was higher than that of asymptomatic infected patients (χ2=8.140, P=0.004). The re-positive rate of domestic patients was higher than that of imported patients (χ2=9.178, P=0.002). The counts of CD3+ (P=0.038), CD4+ (P=0.048) and CD8+ (P=0.040) T lymphocytes in the negative group were higher than those in the positive group. The binary logistic regression analysis showed that the clinical classification and CD8+ T lymphocyte count were independent risk factors affecting the recurrence of virility. Conclusion    The gender, origin, T lymphocyte subsets count and clinical type are the influencing factors for re-positive result, and clinical type and CD8+ T lymphocyte count are the independent influencing factors for re-positive result. Therefore, improving the immunity of infected patients, as well as early detection and timely treatment are effective means to reduce the re-positive occurrence.

The target of celastrol acting on HSP60 against pulmonary fibrosis / 药学学报

Celastrol, extracted from Tripterygium wilfordii, is a natural pentacyclic triterpene compound, which has an anti-pulmonary fibrosis effect. However, its effect, binding targets and regulatory mechanism in pulmonary fibroblasts remain unclear. In this study, we found that celastrol could prevent fibroblast-myofibroblast transformation (FMT) by significantly inhibiting transforming growth factor β1 (TGFβ1)-induced α-smooth muscle actin and type I collagen expression. Previous studies suggested that heat shock protein 60 (HSP60) may be the target of celastrol. This study confirmed the direct interaction between celastrol and HSP60 through cellular thermal shift assay and surface plasmon resonance experiment, and demonstrated that the KD value of celastrol binding to HSP60 was 8.59 μmol·L-1. Further studies showed that knockdown of HSP60 promoted TGFβ1-induced FMT, especially in the medium and low dose TGFβ1 treatment group, and that the anti-FMT effect of celastrol was significantly weakened after HSP60 knockdown. These results indicated that HSP60 was involved in maintaining the resting state of fibroblasts, and the anti-FMT effect of celastrol was dependent on HSP60. Furthermore, the autophagy promotion and antioxidant effects of celastrol were also weakened after HSP60 knockdown. In conclusion, celastrol inhibits FMT by targeting HSP60, thus exerting anti-pulmonary fibrosis function.

Fasting venous blood was collected and serum was separated. The concentration of Hcy in serum was detected by enzyme linked immunosorbent assay(ELISA), and chemiluminescence immunoassay was used to detect the concentration of VitB12 and folic acid. Pearson linear correlation analysis was used to evaluate the correlation between Hcy and clinical parameters. Multivariate linear regression analysis was used to evaluate the main factors which affect Hcy level. Receiver operating characteristic(ROC)curve was designed to analyze the diagnostic value of serum Hcy, VitB12 and folic acid in DR.RESULTS: The concentration of serum Hcy in DR group was 16.52±3.54 μmol/L, which was significantly higher than that in DM group(10.86±3.47 μmol/L)and control group(6.84±1.39 μmol/L; all P<0.05); The concentration of VitB12 in the serum of the control group was 501.79±108.95 pmol/L, which was higher than that in DM group(478.57±57.85 pmol/L)and DR group(455.88±181.49 pmol/L), but the difference was not statistically significant(P=0.054); The concentration of folic acid in serum of control group was 10.31±2.43 nmol/L, which was higher than that of DM group(9.94±1.90 nmol/L)and DR group(7.27±2.79 nmol/L), and the difference between DR group and DM group was statistically significant(P<0.05); In DR group, Hcy expression was weakly positively correlated with triglyceride and low density lipoprotein(r=0.208, P=0.043; r=0.240, P=0.019). Multivariate linear regression showed that low density lipoprotein was an important factor which affect the expression of Hcy in DR patients. ROC curve shows that Hcy has important value in the diagnosis of DR.CONCLUSIONS: Hcy, VitB12 and folic acid are differentially expressed in DR group, DM group and normal control group. Hcy may be involved in the pathogenesis of DR, and it has important value in the diagnosis of DR. In addition, low density lipoprotein is also an important factor which affects the expression of Hcy.

Early effect of extracorporeal membrane oxygenation and factors related to early outcome in adult patients with fulminant myocarditis / 中华心血管病杂志

Objective: To evaluate the efficacy within the first 24 h post extracorporeal membrane pulmonary oxygenation (ECMO) and the impact of early efficacy on the prognosis of adult patients with fulminant myocarditis (FM). Methods: This retrospective case analysis study included hospitalized patients (age≥18 years) who were diagnosed with fulminant myocarditis from November 2016 to May 2021 in the First Affiliated Hospital of Zhengzhou University. Patients were divided into survival or non-survival groups according to treatment outcomes. The age, sex, treatments, drug use, ECMO use, clinical and laboratory data (before and 24 h after the use of ECMO) were analyzed. The change rate of clinical and laboratory data after 24 h use of ECMO was calculated to find differences between two groups. Multivariate logistic regression was used to analyze the related factors with in-hospital death and complication between the two groups. Results: A total of 38 FM patients treated with ECMO were included. There were 23 cases (60.5%) in the survival group, aged (39.6±13.7) years, and 17 (73.9%) cases were female. The total ECMO time was (134.4±71.3)h. There were 15 cases (39.5%) in non-survival group, aged (40.0±15.8) years, and there were 12(80.0%) female, the ECMO time was (120.1±72.4) h in this group. The proportion of tracheal intubation and continuous renal replacement therapy in the survivor group and dosage of norepinephrine within 24 h after ECMO implantation were significantly less than in non-survival group (all P<0.05). There was no significant difference in all efficacy related biochemical indexes between two groups before ECMO use. The levels of lactic acid, procalcitonin, creatinine, alanine aminotransferase, aspartate aminotransferase, creatine kinase-MB, cardiac troponin I and N-terminal B-type natriuretic peptide prosoma were significantly less in survival group than in non-survival group at 24 h after the use of ECMO (all P<0.05). Results of multivariate logistic regression analysis showed that the higher 24 h change rate of creatinine (OR=0.587, 95%CI 0.349-0.986, P=0.044) and creatine kinase-MB (OR=0.177, 95%CI 0.037-0.841, P=0.029) were positively correlated with reduced risk of in-hospital mortality. The central hemorrhage and acute kidney injury in survival group were less than in non-survivor group (P<0.05). Conclusions: After 24 h early use of ECMO in FM patients, the improvement of various efficacy related biochemical test indexes in the survival group was better than that in the non-survival group. Faster reduction of creatine kinase-MB and creatinine values within 24 h ECMO use is positively correlated with reduced risk of in-hospital mortality in adult patients with FM.

Role of complement system in the pathogenesis of uveitis / 国际眼科杂志(Guoji Yanke Zazhi)

Uveitis is a group of inflammation diseases involving the iris, ciliary body, choroid, vitreous body, retina and retinal vessels, which can lead to visual deterioration and even visual loss. The pathogenesis of uveitis is complex and diverse, including infection, autoimmunity, trauma, physical and chemical injury, immune genetic mechanism and so on. Recent studies have shown that the activation of complement system is one of the pathogenesis of uveitis. Various complement proteins, including CFH, CFB, CFI, MAC, CD59 and so on, regulate host tissue damage through a rigorous mechanism mediated by the complement system. And studies have found that those complement proteins are involved in the occurrence and development of uveitis at the gene level and biological function. In addition, complement components like C2, C3, C4 and C5 can affect the pathogenesis of uveitis in terms of copy number variation, gene polymorphism and the regulation of T-cell-mediated autoimmune response. Therefore, complement inhibition therapy and related gene therapy provide new ideas and targets for the treatment of uveitis.

The texture analysis of MRI diffusion-weighted imaging for predicting prognosis of neonatal hypoglycemic encephalopathy / 中华全科医师杂志

Objective:To investigate the prognostic value of texture analysis of MRI diffusion weighted imaging (DWI) for neonatal hypoglycemic encephalopathy (HE).Methods:The clinical data and MRI data of 119 patients with neonatal HE admitted to Children′s Hospital of Nanjing Medical University from July 2013 to September 2020 were retrospectively analyzed. The children were followed up to 7—8 months and scored by Bayley scales of infant and toddler development. According to the overall development index, the children were divided into three groups: normal group (≥85, group A, n=42), mild developmental retardation group (70－84, group B, n=46) and developmental retardation group (≤69, group C, n= 31). The whole brain region (except sulcus and cisterna) was delineated as region of interest (ROI) by LIFEx 3.4 software in MRI apparent diffusion coefficient images. A total of 37 parameters were calculated automatically by the software, The clinical data, including gender, gestational age, age at MRI scan, birth weight, mode of delivery, history of asphyxia at birth, maternal preeclampsia or diabetes, minimum blood glucose, duration of hypoglycemia, neonatal behavioral neurological assessment (NBNA), presence or absence of polycythemia); the texture parameters, including histogram, volume, gray level co-occurrence matrix (GLCM), gray level run length matrix (GLRLM), neighborhood gray tone difference matrix (NGTDM), gray level size zone matrix (GLSZM), in the three groups were analyzed; and the diagnostic efficacy of clinical parameters and texture parameters was analyzed. Multivariate Logistic regression was used to analyze statistically significant clinical parameters and texture parameters, and receiver operating characteristic curve (ROC) was used to evaluate the prognostic efficacy of these parameter for neonatal HE. Results:There were no significant differences in gender, gestational age, age at MRI scan, delivery mode and blood glucose minimum among the three groups ( P>0.05). There were significant differences in birth weight [(3 150±130)g, (3 020±220)g, (2 880±140)g, F=-0.31, P=0.015], history of suffocation (10 cases, 18 cases, 20 cases, P=0.001), history of maternal diabetes or preeclampsia (14 cases, 29 cases, 21 cases, P=0.002), blood glucose duration [(5.0±0.2)d, (8.0±0.4)d, (14.0±1.7)d, F=-3.09, P=0.030] and NBNA scores (32.0±3.2, 28.0±2.6, 22.0±1.9, F=-4.21, P=0.010) among three groups. There were significant differences in kurtosis and entropy of histogram (2.57±1.12, 3.66±0.98, 4.23±0.37, F=3.54, P=0.010;5.89±1.09, 7.67±2.12, 8.92±1.62, F=-4.42, P=0.020); energy, contrast and dissimilarity of GLCM (0.48±0.01, 0.36±0.02, 0.23±0.01, F=-3.12, P=0.001;2 419±21, 3 354±31, 4 313±26, F=-4.16, P=0.020;126±14, 153±23, 344±43, F=-3.50, P<0.001); long run emphasis of GLRLM (0.78±0.15, 1.12±0.12, 1.76±0.31, F=-4.13, P=0.006), run length non-uniformity and run percentage (71.7±13.9, 96.6±10.7, 104.1±13.5, F=-0.98, P=0.001;0.91±0.05, 0.84±0.21, 0.72±0.17, F=2.97, P=0.010); coarseness and busyness of NGTDM [0.09±0.01, 0.13±0.03, 0.26±0.07, F=-1.95, P=0.003;0.16(0.04, 4.14), 0.32(0.05, 9.84), 0.45(0.15, 10.14), H=-3.24, P=0.030], short-zone emphasis and short-zone high gray length emphasis of GLSZM (4.74±0.45, 3.44±1.03, 1.88±0.67, F=-3.14, P=0.040; 278 963±239, 164 607±544, 111 653±618, F=-3.84, P=0.001) among three groups. Multivariate Logistic regression showed that duration of hypoglycemia, NBNA score, energy, kurtosis, run percentage and short zone effect were independent risk factors for poor prognosis of neonatal HE ( OR=7.43, 4.09, 1.10, 2.11, 1.36, 1.68, P=0.002, 0.027, 0.001, 0.006, 0.007, 0.010, respectively). ROC curve showed that for combined hypoglycemic duration, NBNA and texture parameters, the area under the curve (AUC) was the highest (AUC=0.94, P<0.001). Conclusion:Texture analysis of the MRI diffusion weighted imaging can predict the prognosis of neonatal hypoglycemic encephalopathy at an early stage, which has better prediction efficiency when combined with clinical features.

Volatile Oils from Chinese Medicine in Prevention and Treatment of Breast Cancer： A Review / 中国实验方剂学杂志

Breast cancer is a systemic malignant tumor caused by multiple pathogenic factors， and its pathological mechanism is complex and has not been clarified so far. It has gradually become the largest killer threatening women's life. The common method for the treatment of breast cancer is lesion resection combined with radiation and chemical therapy， endocrine therapy， or targeted therapy. However， due to the limitations of western medicine therapies， there are still considerable breast cancer patients with poor disease control and high tumor recurrence rate in clinical practice. At the same time， the side effects and complications produced by these therapies affect the quality of life of patients. Therefore， it is urgent to develop new drugs or find safe and effective alternative therapies against breast cancer. Volatile oil （VO）， as a unique volatile component of Chinese herbal medicines， has anti-inflammatory， antiviral， and anti-tumor activities. It has been applied in the treatment of breast cancer and has demonstrated good efficacy by exerting the unique effects of strengthening healthy Qi， eliminating pathogenic factors， moving Qi， resolving stasis， warming Yang， soothing liver， and relieving depression. The recent studies have confirmed that VO and its chemical components can prevent and treat breast cancer via multiple mechanisms， while there is a lack of systematic review. The relevant literature published in recent years has demonstrated that VO can inhibit the occurrence and development of breast cancer by regulating the level of estrogen， inhibiting the proliferation and inducing the apoptosis of cancer cells， enhancing immunity， resisting inflammation， and regulating emotions.

ObjectiveTo explore the effect of Jinshui Xiangsheng prescription on the five-year clinical survival outcome of patients with advanced prostate cancer. MethodFrom May 1, 2014 to May 1, 2016, patients with advanced prostate cancer from Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine and the Urology Department of the Second Affiliated Hospital of Nanjing University of Chinese Medicine were collected and treated with Jinshui Xiangsheng prescription (155 cases in the observation group). According to age and Gleason score, the patients without Jinshui Xiangsheng prescription were matched in a ratio of 1∶1 (155 cases in the control group). The androgen resistance rate, survival rate, median survival time, and median progress free survival time in 1, 3, 5 years were observed. The prognostic factors of advanced prostate cancer were analyzed and screened out by Chi-square test, t test, Kaplan-Meier and Cox survival analysis. ResultThe androgen resistance rates in the observation group in 1， 3， 5 years were 9.0% （14/155）， 72.3% （112/155）， and 92.9% （144/155）， respectively， and those in the control group were 20.6% （32/155）， 87.7% （136/155）， and 97.4% （151/155）. The 1-year （χ2=8.271，P<0.01）and 3-year （χ2=11.613，P<0.01） androgen resistance rates in the observation group were significantly lower than those in the control group. The median survival time and median progress free survival time in the observation group were （26.35±9.01） months and （11.02±4.40） months， respectively， and in the control group were （22.31±9.21） months and （9.87±5.12） months， respectively. The median survival time and median progress free survival time in the observation group were significantly longer than those in the control group （P<0.05， P<0.01）. The cumulative survival rates in 1， 3， 5 years in the observation group were 96.1% （149/155）， 80.6% （125/155）， and 39.4% （61/155）， respectively， and those in the control group were 94.2% （146/155）， 60.0% （93/155）， and 22.6% （35/155）， respectively. The 3-year （χ2=15.828，P<0.01） and 5-year （χ2=10.201，P<0.01） cumulative survival rates in the observation group were significantly higher than those in the control group. The monofactor analysis showed that the prognostic factors involved in Gleason score， initial prostate specific antigen （PSA）， tumor location， tumor stage， castration regimen， radiotherapy， chemotherapy， complete androgen blockade （CAB）， and Jinshui Xiangsheng prescription （P<0.05， P<0.01）. The multivariate analysis showed that initial PSA， tumor location， and tumor stage were the risk factors affecting the survival time of patients with advanced prostate cancer， whereas Jinshui Xiangsheng prescription， castration regimen， chemotherapy， radiotherapy， and CAB were the independent protective factors affecting the prognosis of advanced prostate cancer. ConclusionJinshui Xiangsheng prescription has a protective effect on the survival of patients with advanced prostate cancer， which reduces the androgen resistance rate and death risk of advanced prostate cancer， thus benefiting the survival of patients. Therefore， it deserves further promotion.

Etiology and Pathogenesis of Hepatolenticular Degeneration Caused by Latent Toxin Blocking Collaterals / 中国实验方剂学杂志

Hepatolenticular degeneration（HLD），also known as Wilson disease （WD）， is a genetic disorder characterized by copper metabolism disorder caused by ATP7B gene mutation. Specifically， due to the ceruloplasmin synthesis disorder induced by gene mutation，copper cannot be excreted through bile，which results in pathological deposition of copper in various organs and damage to organs such as the brain and the liver. The incidence of WD in Chinese is significantly higher than that in the world. Copper chelating agents， such as D-penicillamine and dimercaptosuccinic acid， are used as the main therapeutic agents in western medicine. However， many clinical adverse events limit the application of these drugs. Traditional Chinese medicine （TCM） has its characteristics in the treatment of WD. As confirmed by long-term research on TCM clinical diagnosis and treatment，MD has become TCM dominant disease. In spite of many views about the etiology and pathogenesis of WD，a consensus has not been reached so far. Based on the theory of latent pathogen in TCM and the pathological mechanism of excessive deposition of copper ions in the body，this study proposed that latent toxin is the key etiology of WD，and further elaborated that the latent toxin of WD was inherited from parents and occurred in children and adolescents，which was hidden in the liver and the kidney and damaged the brain. The latent toxin， Yang in nature and dispersing in property， is prone to transform into dampness-heat to block Qi movement and produce phlegm leading to stasis. Furthermore， this study determined latent toxin blocking collaterals as the basic pathogenesis of WD and revealed the complex clinical manifestations of latent toxin blocking collaterals such as liver collaterals，brain collaterals，kidney collaterals，spleen collaterals，stomach collaterals，lung collaterals，heart collaterals， and uterus collaterals. Treatment should follow the basic therapeutic principles of resolving pathogens，removing toxins， and dredging collaterals. This study is expected to provide a theoretical basis for syndrome differentiation and treatment of WD in TCM.

ObjectiveTo observe the clinical efficacy of Gandou Fumu granules （GDFM） in the treatment of Wilson disease （WD） with liver-kidney deficiency and phlegm-blood stasis. MethodNinety WD patients in The First Affiliated Hospital of Anhui University of Chinese Medicine were randomly divided into a control group （45 cases） and a treatment group （45 cases）. All patients were treated with sodium 2，3-dimercaptopropane-1-sulfonate （DMPS）， while those in the treatment group received additional GDFM. All patients were treated for four courses （32 days）. The traditional Chinese medicine （TCM） syndrome scores，clinical effective rate，24 h urinary copper，ceruloplasmin （CER），tumor necrosis factor-α（TNF-α），interleukin-1β（IL-1β），interleukin-6 （IL-6），superoxide dismutase （SOD），glutathione peroxidase （GSH-Px） and malondialdehyde （MDA） levels of the two groups before and after treatment were observed. ResultAfter treatment， the TCM syndrome scores of the two groups decreased （P<0.01），and the score of TCM syndrome in the treatment group was lower than that of the control group （P<0.01）. The total effective rate of the treatment group was 82.22% （37/45）， higher than 57.78% （26/45） of the control group （χ2=6.402，P<0.05）. There was no significant difference in CER before and after treatment in both groups. The post-treatment 24 hour urinary copper increased （P<0.01）， which was higher in the treatment group than that in the control group （P<0.05）. The TNF-α，IL-1β， and IL-6 levels were significantly reduced in both groups after treatment（P<0.01），and the above indicators in the treatment group were significantly lower than those in the control group （P<0.01）. After treatment，the SOD level increased and the MDA level decreased in the control group （P<0.01）， while no significant difference in GSH-Px level was observed. The SOD and GSH-Px levels increased and the MDA level decreased in the treatment group （P<0.01）. After treatment， SOD and GSH-Px levels of the treatment group were higher than those in the control group， while the MDA level was lower than that in the control group（P<0.05，P<0.01）. ConclusionGDFM can improve the TCM syndrome score and clinical efficacy，enhance the copper removing effect，and inhibit the inflammatory response and antioxidative stress in the treatment of WD with liver and kidney deficiency and phlegm-blood stasis.

Intervention of Gandou Fumu Decoction on Liver Fibrosis in Mice with Wilson's Disease Through JNK Signaling Pathway / 中国实验方剂学杂志

ObjectiveTo identify the protective effect and possible mechanism of Gandou Fumu decoction （GDFMD） on liver fibrosis in mice with Wilson's disease. MethodA total of 50 homozygous TXJ mice were randomly divided into five groups， with 10 mice in each group. Ten wild-type mice were selected as a normal group. The GDFMD high， medium， and low-dose groups were given 13.92， 6.96， 3.48 g·kg-1 of GDFMD， respectively. The penicillamine group were given 0.1 g·kg-1 of penicillamine. The model group and the normal group were given the same volume of 0.9% sodium chloride solution once a day for 4 consecutive weeks. The enzyme-linked immunosorbent assay （ELISA） method was performed to detect serum superoxide dismutase （SOD） activity and malondialdehyde （MDA） content. Corresponding kits were used to detect the mitochondrial adenine triphosphate （ATP） content and Na+-K+-ATPase activity in liver tissues. Hematoxylin-eosin （HE） and Masson staining were used to observe the pathological morphology of liver tissue， and transmission electron microscope was used to observe ultrastructural changes of liver tissues in mice. Western blot was used to detect the c-Jun N-terminal kinase， the phosphorylated protein， and the expressions of Caspase-3， B cell lymphoma-2 （Bcl-2）， and Bcl-2 associated X protein （Bax） in c-Jun N-terminal kinase （JNK） signaling pathway. ResultCompared with the normal group， MDA content increased and SOD activity decreased in the model group （P<0.05）. Compared with the model group， SOD activities in the GDFMD high-， medium-， and low-dose groups and the penicillamine group significantly increased （P<0.01）， and MDA content significantly decreased （P<0.05， P<0.01）. Compared with the normal group， ATP content and Na+-K+-ATPase activity significantly decrease in the model group （P<0.05）. Compared with the model group， ATP content and Na+-K+-ATPase activity in the GDFMD medium and high-dose groups and the penicillamine group significantly increased （P<0.05， P<0.01）. The results of the pathological morphology of liver tissue showed that a large number of liver cells degeneration and necrosis， inflammatory cell infiltration， unclear liver lobule structure， and collagen fiber deposition were observed in the model group. Transmission electron microscopy showed that the number of mitochondria in liver tissues significantly reduced， the mitochondria were locally damaged， and the cristae of mitochondria were broken even disappear in the model group. The pathological morphology of liver tissue and mitochondrial structure recovered to varying degrees after medicinal intervention. The results of Western blot suggested that， compared with the normal group， the expression levels of phosphorylation-JNK （p-JNK）， p-JNK/JNK， Caspase-3， and Bax in the liver tissues were up-regulated， while the expression of Bcl-2 was down-regulated in the model group （P<0.05）. The expression levels of p-JNK， p-JNK/JNK， Caspase-3 and Bax were down-regulated and the expression of Bcl-2 was up-regulated in the GDFMD high and medium-dose groups and the penicillamine group （P<0.01）. ConclusionGDFMD can alleviate oxidative stress damage and recover mitochondrial function of TXJ mice with liver fibrosis. The mechanism of GDFMD may be related to regulating the JNK signaling pathway and downstream factors and inhibiting cell apoptosis.

ObjectiveTo investigate the effects of Gandou decoction （GDD） on the mitophagy of hippocampal neurons in toxic milk （TX） mouse model of Wilson disease and explore the protective mechanism of GDD against neuron injury through the PTEN induced kinase 1 （Pink1） /E3 ubiquitin ligase （Parkin） pathway. MethodSixty mice were randomly divided into a blank group， a model group， a penicillamine group （0.09 g·kg-1）， and low- （5.5 g·kg-1）， medium- （11 g·kg-1）， and high-dose （22 g·kg-1） GDD groups， and treated correspondingly by gavage for 8 weeks. Morris water maze， traction test， and pole test were used for the evaluation of animal behaviors. Hematoxylin-eosin （HE） staining and transmission electron microscopy were used to observe cell apoptosis， ultrastructure， autophagy， and mitochondrial structure. The levels of superoxide dismutase （SOD）， reactive oxygen species （ROS）， and malondialdehyde （MDA） were detected by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of Pink1， Parkin， autophagy-associated protein Beclin-1， microtubule-associated protein 1 light chain 3Ⅱ （LC3Ⅱ）， and p62. Western blot was conducted to detect the protein expression of Pink1， Parkin， Beclin-1， LC3Ⅱ/Ⅰ， and p62. ResultCompared with the blank group， the model group showed prolonged escape latency， decreased times of platform crossing， lower score in the traction test， and longer pole climbing time （P<0.01）. Compared with the model group， the medium- and high-dose GDD groups and the penicillamine group showed shortened escape latencies， increased times of platform crossing， higher scores in the traction test， and shortened pole climbing time （P<0.01）. Compared with the blank group， the model group displayed severely damaged neurons and increased autophagosomes. Compared with the model group， the medium- and high-dose GDD groups and the penicillamine group showed improved neuron damage and reduced autophagosomes. The levels of ROS and MDA were higher and SOD was lower in the model group than those in the blank group （P<0.01）， while the levels of the above indicators were reversed by GDD intervention as compared with the model group （P<0.01）. Compared with the blank group， the model group exhibited up-regulated mRNA and protein expression of Pink1， Parkin， LC3Ⅱ， and Beclin-1 and down-regulated p62 （P<0.05）. Compared with the model group， the medium- and high-dose GDD groups showed reduced mRNA and protein expression of Pink1， Parkin， LC3Ⅱ， and Beclin-1 and increased p62 （P<0.05， P<0.01）. ConclusionGDD can significantly inhibit the excessive mitophagy in neurons of TX mice and protect neurons from damage. The mechanism may be related to the regulation of the Pink1/Parkin pathway.

Chemical Components and Pharmacological Activities of Smallanthus sonchifolius （Yacon）：A Review / 中国实验方剂学杂志

Smallanthus sonchifolius， a plant resource with both medicinal and edible values， has been taken as fruit for a long history. Studies have proved that phenolic acids， flavonoids， sesquiterpene lactones， and fructooligosaccharides are the major compounds in S. sonchifolius. The extract of S. sonchifolius demonstrates noticeable antioxidant， anti-inflammatory， antimicrobial， and anti-cancer effects， as well as the activities of lowering blood glucose level， regulating intestinal function and so on. The rhizomes and leaves of S. sonchifolius contain abundant phenolic acids， mainly caffeic acid and its derivatives， which endow S. sonchifolius with remarkable antioxidant effect. Moreover， these substances can reduce blood glucose by improving insulin sensitivity. Fructooligosaccharides are abundant in the tuber of this plant， which can improve intestinal function by regulating intestinal flora. The sesquiterpene lactones in glandular trichomes on the leaf surface can inhibit the proliferation of cancer cells， among which uvedafolin and enhydrofolin have particularly strong activities. Furthermore， the sesquiterpene lactones have obvious inhibitory effect on Gram-positive bacteria. In terms of structure， the number of epoxy groups is linked to the strength of anticancer and antimicrobial effects. In addition， S. sonchifolius contains other compounds such as volatile oils， fatty acids， sterols， diterpenes， p-hydroxyacetophenone derivatives， and octulosonic acid derivatives， thereby exhibiting the pharmacological effects of treating Alzheimer's disease， protecting kidney， and lowering blood lipids. However， the isolation and identification of the main compounds in S. sonchifolius need further exploration， and the mechanism of action remains to be studied. Here we summarized the principal chemical components and pharmacological activities of S. sonchifolius， aiming to give a clue for the comprehensive development and utilization of this plant.

ObjectiveTo study on the correlation between the apparent color， near-infrared spectroscopy and dynamic changes of index constituent content of samples during the processing of steamed Notoginseng Radix et Rhizoma， and to provide reference for the processing process optimization and quality control of this decoction piece. MethodSamples were dried and crushed by setting three steaming temperature gradients of 100-105， 114-118， 130-136 ℃， and sampled at steaming times of 1， 2， 4， 8， 12， 24 h， respectively. The effects of different steaming temperatures and times on the color and absorption of steamed Notoginseng Radix et Rhizoma at different infrared wavelengths were observed， and principal component analysis and cluster analysis were performed on the obtained data by R 4.1.0 and SPSS 21.0 software to observe the changes in color and infrared absorption characteristics of samples. High performance liquid chromatography （HPLC） was employed to determine the content changes of notoginsenoside R1， ginsenoside Rg1， ginsenoside Rb1， ginsenoside Re， 20（S）-ginsenoside Rg3 and 20（R）-ginsenoside Rg3 before and after steaming of Notoginseng Radix et Rhizoma， mobile phase was acetonitrile （A）-water （B） for gradient elution （0-30 min， 19%A； 30-60 min， 19%-44%A； 60-78 min， 44%-74%A； 78-80 min， 74%-100%A； 80-86 min， 100%A； 86-87 min， 100%-19%A； 87-95 min， 19%A） with the detection wavelength of 203 nm. ResultDuring the steaming process of Notoginseng Radix et Rhizoma， with the increase of steaming temperature and time， the b* （yellow-blue value）， L* （brightness）， △E* （comprehensive color difference value） of sample powder showed a decreasing trend， while the a* （red-green value） showed an increasing trend， and the color gradually deepened from gray to brown and dark black. There was no significant difference in the infrared absorption between raw and steamed Notoginseng Radix et Rhizoma sample powder in the low and medium wavelength bands， but significant difference in the infrared absorption of high band， especially in the band of 9 600-10 000 cm-1. HPLC showed that the contents of the original components （notoginsenoside R1， ginsenoside Rg1， Re and Rb1） decreased and 20（S）-ginsenoside Rg3 and 20（R）-ginsenoside Rg3 were newly produced after steaming of Notoginseng Radix et Rhizoma. The content proportion of these six index components reached the best when the steaming temperature at 130-136 ℃ and the steaming time of 1 h. ConclusionThe color and infrared absorption of samples are affected by the dynamic changes of chemical composition during the steaming process， and the composition change is the result of the joint influence of steaming temperature and time. In this paper， through multi-dimensional analysis of the apparent color indexes， the change pattern of near-infrared absorption characteristics and the index components of the samples， the different process parameters of steamed Notoginseng Radix et Rhizoma were evaluated holistically， and the quality transfer pattern of its processing process was initially revealed， which can provide scientific basis for processing optimization and quality evaluation of steamed Notoginseng Radix et Rhizoma.

ObjectiveTo screen the appropriate reference genes for real-time fluorescence-based quantitative polymerase chain reaction（Real-time PCR）analysis of the Andrographis paniculata under methyl jasmonate（MeJA）and various abiotic stresses. MethodThe actin 1（ACT1），actin 2（ACT2），elongation factor（EF-1α），glyceraldehyde-3-phosphate dehydrogenase（GAPDH），tubulin（TUB），polyubiquitin（UBQ）， and 18S rRNA（18S）gene were selected as candidate reference genes based on the RNA-seq data of high temperature，drought， UV， and MeJA. The expression of seven candidate reference genes in the A. paniculata leaves was assessed by Real-time PCR，and the stability was analyzed by geNorm，NormFinder，BestKeeper， and Refinder. ResultThe results of stability evaluated by geNorm，NormFinder， and BestKeeper were not the same due to different indicators. As analyzed by Refinder， for the stability of the expression， the genes were ranked as UBQ>18S>EF-1α>ACT2>ACT1>GAPDH>TUB under high temperature stress， ACT1>UBQ>EF-1α>18S>ACT2>GAPDH>TUB under drought stress， EF-1α>TUB>ACT2>UBQ>18S>GAPDH>ACT1 under UV stress， and ACT1>EF-1α>UBQ>ACT2>18S>TUB>GAPDH under MeJA stress. Among them，18S gene was not suitable as an internal reference gene duo to its high expressive abundance. This study also verified the relative expression level of andrographolide synthesis-related gene hydroxy-methylglutaryl-CoA synthase （HMGS） in the four stresses on the basis of transcriptome data，and found that the Real-time PCR results of appropriate internal reference genes were accurate and reliable. ConclusionUBQ-ACT1-UBQ，EF-1α-TUB，and ACT1-EF-1α were the suitable combinations under stresses of high temperature，drought，UV， and MeJA. This study is expected to provide references for the research on function regulation and expression of genes in A. paniculata under high temperature，drought，UV， and MeJA stresses.
