ABSTRACT

ObjectiveMalignant tumor has become a serious public health problem, threatening human health. Chinese herbal medicine has become a research focus as it is "simple, convenient, inexpensive, and effective" and exerts anti-tumor effect through "multiple components, multiple targets, and multiple pathways". This paper reviews the anti-tumor effect of triterpenes, polysaccharides and other compounds in Poria, which is expected to serve as a reference for research on the anti-tumor effect of Poria. MethodBasic research, clinical observation, and reviews were retrieved from PubMed, Google Scholar, and China National Knowledge Infrastructure (CNKI) (1995—2022) with the keywords of Poria and malignant tumor. ResultThe main active components of Poria such as triterpenes represented by pachymic acid and polysaccharides represented by pachyman had extensive pharmacological effects in inhibiting the proliferation of malignant tumors, inducing apoptosis, suppressing invasion and metastasis, regulating the immune function, and improving the quality of life. In addition, the cultivation method, medicinal part, growth environment, and harvest cycle of the medicinal plant, and dosage form and processing method of Poria affected the content of different active components. ConclusionThe active components of pachymic acid and triterpenoids have great potential in antitumor, which, however, face the challenges in innovation and quality clinical trials. The lack of quality control standard of Poria may affect the anti-tumor effect, and efforts should be made to formulate specific standard for quality control. The antitumor of Poria is science-based and thus it has broad application prospect. Nevertheless, more efforts should be made before the practical application.

ABSTRACT

The present study developed an ultra-fast liquid chromatography coupled with triple quadrupole-linear ion trap composite mass spectrometry(UHPLC-QTRAP-MS) to simultaneously determine the content of potential active components in Scutellariae Barbatae Herba and also to provide a reference approach for screening out the differential quality control components among different batches of Scutellariae Barbatae Herba. Chromatographic separations were conducted on a Thermo Acclaim~(TM) RSLC 120 C_(18) column(3.0 mm×100 mm, 2.2 μm) in a gradient program. The mobile phase consisted of 0.1% aqueous formic acid and acetonitrile, and the column temperature was maintained at 40 ℃. The flow rate was 0.4 mL·min~(-1) and the injection volume was 2 μL. The targeted compounds were monitored in the multiple reaction monitoring(MRM) mode. The acquired data were processed by hierarchical cluster analysis(HCA) and partial least square discriminant analysis(PLS-DA). Sixteen compounds all showed good linear relationship within the corresponding linear ranges and the R~2 values were all higher than 0.993 2. The RSDs of precision, repeatability, and stability were less than or equal to 3.7%. Mean recovery rates were in the range of 95.67% and 104.8% with RSDs≤3.2%. According to HCA and PLS-DA, all samples were clustered into four categories. Scutellarin, acteoside, scutellarein, and scutebarbatine X(VIP>1) were considered as differential chemical markers in the four categories. In conclusion, the developed method can be used for the simulta-neous determination of the multiple components and quality control of Scutellariae Barbatae Herba.

ABSTRACT

ObjectiveTo observe the effect of Xianlian Jiedu prescription (XLJDP) on the proliferation, apoptosis, and migration of cancer-relative endothelial (CRE) cells, and to decipher the mechanism of XLJDP in regulating angiopoietin2 (Ang2) to maintain CRE cell homeostasis and inhibit tumor neovascularization. MethodHuman umbilical vein endothelial cell line (HUVEC-c) was induced into CRE cells in the human colorectal cancer HCT-116 cell-conditioned medium. The CRE cells were assigned into the blank group, conditioned medium group, and XLJDP groups (1, 2, 3 g·L-1) and treated for 48 h. The proliferation of CRE cells was detected by methyl thiazolyl tetrazolium (MTT) colorimetry. The morphological changes of CRE cells were observed via an inverted microscope. The apoptosis rate was detected by flow cytometry. Wound healing test and Transwell migration assay were employed to detect the 2D/3D migration ability of CRE cells. The protein levels of vimentin, N-cadherin, matrix metalloproteinase-9 (MMP-9), and Ang2 in CRE cells were measured by Western blot. ResultThe MTT results showed that the cell viability was higher in the conditioned medium group than in the blank group (P<0.05). Compared with the conditioned medium group, XLJDP decreased the cell proliferation rate (P<0.01) and changed the cell morphology. The total apoptosis rates of all the XLJDP groups were higher than that of the conditioned medium group (P<0.01). The 2D and 3D migration abilities of the conditioned medium group were higher than those of the blank group (P<0.05, P<0.01). Compared with the conditioned medium group, XLJDP at all the concentrations weakened the 2D migration ability (P<0.01) and medium- and high-concentration XLJDP weakened the 3D migration ability (P<0.01). The protein levels of N-cadherin, Vimentin, MMP-9, and Ang2 were up-regulated in the conditioned medium group compared with those in the blank group (P<0.05, P<0.01). Compared with the conditioned medium group, XLJDP at all the concentrations down-regulated the protein level of Ang2 (P<0.05, P<0.01), and medium- and high-concentration XLJDP down-regulated those of N-cadherin, vimentin, and MMP-9 protein (P<0.01). ConclusionXLJDP may inhibit the proliferation, migration, differentiation, and apoptosis of CRE cells by down-regulating the expression of Ang2, inhibiting tumor neovascularization, and maintaining the cell homeostasis.

ABSTRACT

ObjectiveTo study the effect of Xianlian Jiedu prescription (XLJDP) on the activation of nuclear transcription factor-κB (NF-κB) signaling pathway induced by bromodomain-containing protein 4 (Brd4) in hypoxic microenvironment and to explore its mechanism in inhibiting the proliferation of colorectal cancer HT-29 cells. MethodThe human colorectal cancer HT-29 cells were cultured in a hypoxic incubator or normoxia incubator and treated with XLJDP at 0.8,1,1.2,1.6,3.2,6.4,and 12.8 g·L-1 for 48 h, respectively. Following the detection of cell vitality using methyl thiazolyl tetrazolium (MTT) colorimetry, the effects of XLJDP (1.25,2.5,and 5 g·L-1) on the cell mitochondrial membrane potential were determined using a fluorescent probe (JC-1), and the apoptosis of colorectal cancer HT-29 cells was detected by flow cytometry. The cell colony formation assay and 5-ethynyl-2'-deoxyuridine (EDU) staining were conducted to test the proliferation of colorectal cancer HT-29 cells. The Western blot was carried out to measure the expression levels of Brd4 and its downstream relevant proteins such as c-Myc and hexamethylene bisacetamide-inducible protein 1 (HEXIM1), as well as the effects of XLJDP on related proteins in the NF-κB signaling pathway. ResultCompared with the blank control group, XLJDP at 0.8,1,1.2,1.6,3.2,6.4,and 12.8 g·L-1 inhibited the vitality of colorectal cancer HT-29 cells (P<0.05 , P<0.01), with the median inhibitory concentration (IC50) under the hypoxic condition higher than that under the normoxia condition. Compared with the blank control group, XLJDP at 1.25,2.5,and 5 g·L-1 significantly decreased the mitochondria membrane potential, enhanced the apoptosis (P<0.05,P<0.01), and lowered the number of cell colonies and also the EDU-positive cells (P<0.05, P<0.01). The results of Western blot showed that compared with the blank control group, XLJDP at 1.25,2.5,and 5 g·L-1 down-regulated Brd4, c-Myc, p-NF-κB p65, and p-IκBα protein expression to varying degrees and up-regulated the expression of HEXIM1 (P<0.05, P<0.01). ConclusionIn the hypoxic microenvironment, XLJDP inhibits the proliferation of colorectal cancer HT-29 cells regulated by Brd4, which may be related to its inhibition of the activation of NF-κB signaling pathway.

ABSTRACT

ObjectiveTo explore the effect of Xianlian Jiedu prescription (XLJDP) on the proliferation and glycolysis of human colorectal cancer HCT-116 cells and the underlying mechanism. MethodHCT-116 cells were cultured with XLJDP and then the survival rate was examined by methyl thiazolyl tetrazolium (MTT) assay. The effect on the HCT116 cell proliferation was detected by colony formation assay and 5-ethynyl-2′-deoxyuridine (EDU) incorporation assay. The amount of glucose consumed by HCT-116 cells was measured by glucose test kit, and the amount of produced lactic acid was determined by lactic acid test kit 48 h after the treatment with XLJDP. The expression of glycolysis-related proteins mammalian target of rapamycin (mTOR), phosphorylated mTOR (p-mTOR), glucose transporter 1 (GLUT1), and lactate dehydrogenase (LDHA) was detected by Western blot. ResultThe half-maximal inhibitory concentration (IC50) of XLJDP against HCT-116 cells was 6.82 g·L-1. Compared with the blank group, XLJDP (1.625, 3.25, 6.50 g·L-1) inhibited the proliferation of HCT-116 cells (P<0.05, P<0.01). Moreover, compared with the blank group, XLJDP (1.625, 3.25, 6.50 g·L-1) suppressed glucose uptake and lactic acid production in a dose-dependent manner (P<0.05, P<0.01). The expression of p-mTOR/mTOR, LDHA, and GLUT1 was down-regulated by XLJDP (P<0.05, P<0.01). ConclusionXLJDP can significantly inhibit the proliferation and the Warburg effect of glycolysis in colorectal cancer cells by regulating the mTOR signaling pathway and the down-regulating the expression of LDHA, GLUT1, and other key proteins and enzymes in glycolysis.

ABSTRACT

ObjectiveTo analyze the transcriptome characteristics of Xianlian Jiedu prescription (XLJDP) in the intervention of colorectal carcinoma by high-throughput cDNA-sequencing (RNA-seq). MethodNinety male C57BL/6 mice were randomly divided into the control group, colorectal carcinoma due to dampness, heat, stasis, and toxin model group, and XLJDP group, with 30 mice in each group. Mice in the model group and XLJDP group were fed a high-fat diet and provided with azoxymethane and dextran sodium sulfate (AOM/DSS) for inducing colorectal carcinoma. Those in the XLJDP group were further treated with intragastric administration of 12.9 g·kg-1 XLJDP since the day of modeling for 112 days. The colorectal tissues were collected from each group 4 h after the last drug treatment and stained with hematoxylin-eosin (HE) and methylene blue for observing the pathological changes. The total RNA was extracted from colorectal tissues for RNA-Seq-based transcriptome profiling, followed by gene oncology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis and the screening and verification of differentially expressed genes. ResultCompared with the model group, XLJDP significantly relieved the colorectal congestion and edema and decreased tumor number and volume in mouse colorectal tissues. The methylene blue staining results indicated that XLJDP significantly suppressed the development of aberrant crypt foci (ACF,P<0.01). As revealed by HE staining, XLJDP significantly alleviated the injury and dysplasia of colorectal tissues. Transcriptome analysis identified 615 differentially expressed genes (446 up-regulated and 169 down-regulated) between the model group and the blank group and 54 differentially expressed genes (29 up-regulated and 25 down-regulated) between the XLJDP group and model group. XLJDP mainly affected the expression of NIMA-related protein kinase 7 gene (Nek7, P<0.01), Mucin 16 (Muc16, P<0.01), SiahE3 ubiquitin protein ligase family member 3 (Siah3, P<0.01), regenerating islet-derived protein 3-gamma (Reg3g, P<0.01), RNA polymerase Ⅱ elongation factor-associated factor 2 (Eaf2, P<0.01), transforming growth factor‐alfa gene (TGF-α, P<0.05), secretoglobin family 1A member 1 (Scgb1a1, P<0.05), family with sequence similarity 227 member B (Fam227B, P<0.05), cytochrome P450 family 2 subfamily c polypeptide 40 (Cyp2c40, P<0.01), and ankyrin repeat and EF-hand domain containing protein 1 (Ankef1, P<0.05). Enrichment analysis showed that intestinal epithelial cell proliferation, metabolism of xenobiotics by cytochrome P450, and arachidonic acid metabolism signaling pathway were significantly enriched. ConclusionXLJDP is able to interfere with colorectal tumorigenesis and development due to dampness, heat, stasis, and toxin in mice, which has been proved by transcriptome analysis to be related to the regulation of metabolism-related pathways.

ABSTRACT

Objective:To retrospectively investigate the incidence of malnutrition in patients with gastric cancer in China, and to explore the applicability of Global Leadership Initiative on Malnutrition (GLIM) diagnostic criteria.Methods:Data were extracted from National Multi-center Investigation and Study on Dynamic Changes of Nutritional Status of Inpatients database led by Geriatric Nutrition Support Group of the Chinese Society of Parenteral and Enteral Nutrition. A retrospective analysis in patients with gastric cancer was conducted. Involuntary weight loss, low body mass index (BMI) and muscle mass loss were adopted as phenotypic indicators in GLIM criteria for malnutrition diagnosis and the application of GLIM criteria for malnutrition diagnosis in patients with gastric cancer was evaluated.Results:In a total of 563 gastric cancer patients, 203 cases were diagnosed with malnutrition per GLIM criteria and 193 cases without malnutrition were identified as control using 1:1 propensity score matching. There were significant differences in body weight, BMI, right calf circumference, right hand grip strength, total cholesterol, hemoglobin, albumin and total protein between malnutrition group and non-malnutrition group ( P < 0.05). After muscle mass loss was removed from the phenotype indicators in GLIM criteria, the hospitalization duration in patients with malnutrition was (16.15±7.04) days compared with (14.28±6.70) days in patients without malnutrition, demonstrating statistically significant difference ( χ2= 0.442, P = 0.007). Conclusions:Gastric cancer patients showed high incidence of malnutrition. The cut-off value of calf circumference reported in foreign populations may be unsuitable to apply in Chinese population. Further clinical researches are needed to determine the optimal cut-off calf circumference value for Chinese individuals.

ABSTRACT

Objective:To analyze the relationship between nutritional status and frailty among elderly inpatients from cardiology department.Methods:A cross-sectional study was conducted in a total of 519 patients aged 65-92 years old who were admitted to cardiology department between September 2018 and February 2019. Mini nutritional assessment short form (MNA-SF) was used to assess the nutritional status. Fried phenotype was used to assess frailty status. The nutritional status and frailty in patients with different diseases, age and body mass index were analyzed, as well as the nutritional status of patients in different frailty strata.Results:The mean age was 75.12 years (range: 65-92 years). The prevalence of malnutrition risk was 28.9% (150/519), malnutrition 3.3% (17/519) and frailty 23.5% (122/519). When stratified by disease, the subgroup with chronic heart failure showed the highest prevalence of malnutrition and frailty (63.6% and 50.0%, respectively). The prevalence of malnutrition risk (22.8%, 35.5%), malnutrition (3.0%, 3.6%) and frailty (15.3%, 32.3%) were higher in patients ≥ 75 years compared with those aged 65 years - 75 years. MNA-SF score was negatively correlated with age( r = -0.134, P = 0.002). Fried phenotype score was positively correlated with age ( r = 0.319, P < 0.01). As for stratification based on BMI, the majority (62.6%) patients were overweight or obese (BMI ≥ 24.0 kg/m 2) and the prevalence of malnutrition risk in this subgroup was 21.2% (69/325). The prevalence of malnutrition risk in patients with normal BMI was 38.7% (70/181). The subgroup with BMI<18.5 were either at malnutrition risk or with malnutrition. MNA-SF score was positively correlated with BMI ( r = 0.353, P < 0.01). There was no significant difference in the prevalence of pre-frailty and frailty among different BMI groups. The prevalence of malnutrition was the highest in the frailty group (8.2%), followed by the pre-frailty group (2.0%). Fried phenotype score was negatively correlated with MNA-SF score( r = -0.291, P < 0.01). Logistic regression analysis showed that frailty was an independent risk factor for malnutrition, and the risk of malnutrition in frailty patients was 4.818 (95% CI:1.701~13.644) times higher than that in non-frailty patients. Conclusions:The prevalence of malnutrition risk and frailty was high in the elderly inpatients from cardiology department. Frailty patients had a higher incidence of malnutrition and required more attention.

ABSTRACT

Objective:To investigate the protective effect of overexpressed tripartite motif containing (TRIM27) on severe acute pancreatitis (SAP) in mice and its possible mechanism.Methods:Twenty-four mice were randomly divided into the sham operation + control virus group (AAV-GFP group), sham operation + overexpression of TRIM27 group (AAV-TRIM27 group), SAP + control virus group (SAP+AAV-GFP group), SAP + overexpression of TRIM27 group (SAP + AAV-TRIM27 group), with 6 mice in each group. SAP model of mice was established by intraperitoneal injection of L-arginine (4 mg/kg). The sham operation group was injected with equal volume of normal saline, and the virus group was injected with control or TRIM27 overexpression adeno-associated virus (2×10 11 μg/ per mice). The serum and pancreatic tissue samples were collected 72 h after modeling. The levels of serum amylase, lipase, tumor necrosis factor α (TNF-α), interleukin-1b (IL-1b), IL-6, macrophage chemoattractant protein-1 (MCP-1) and the expression of malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) in pancreatic tissue were detected by enzyme-linked immunosorbent assay. Hematoxylin eosin staining was used to observe the pathological damage of pancreatic tissue. The expressions of myeloperoxidase (MPO) and Ly6g positive inflammatory cells in mouse pancreas were observed by immunohistochemistry. The expression of p-p65, p65, p-ASK1, ASK1, p-JNK, JNK, p-p38 and p38 in pancreatic tissue were detected by Western blot. Results:The expression of TRIM27 in pancreatic of mice was significantly down regulated after SAP ( P<0.05); after overexpression of TRIM27 by adeno-associated virus, the expression of TRIM27 in mouse pancreas was significantly up-regulated ( P<0.05). There was no significant difference in the indexes of mice between the AAV-GFP group and AAV-TRIM27 group ( P>0.05). Compared with the SAP + AAV-GFP group, the levels of serum amylase, lipase, TNF-α, IL-1b, IL-6 and MCP-1 in mice of the SAP + AAV-TRIM27 group were significantly decreased, MDA in pancreatic tissue was decreased, SOD and GSH were increased, MPO and Ly6g inflammatory cells were significantly decreased, and p-p65, p-ASK1, p-JNK, and p-p38 protein expression were down regulated. Conclusions:Overexpression of TRIM27 alleviates SAP in mice by inhibiting inflammatory response and oxidative stress, and its mechanism may be through inhibiting NFκB/MAPK signaling pathway.

ABSTRACT

Child Compound Endothelium Corneum(CCEC)has the effects in invigorating the spleen and appetizing the appetite, and dissolving the accumulation of food. The recent studies have proved that it could improve gastrointestinal motility, restore physiological gastrointestinal peristalsis, increase gastrointestinal digestive motility, and enhance appetite. This trial aimed to evaluate its clinical efficacy and safety in the treatment of children's anorexia(spleen-stomach disharmony). A total of 240 children with anorexia in line with the inclusion and exclusion criteria were selected and randomly divided into experimental group and control group, with 120 in each group. Patients in the experimental group took CCEC and Erpixing Granules simulant. Patients in the control group took Erpi-xing Granules and CCEC simulant. After 21 days of treatment, there was no statistical difference in the recovery rate of anorexia, reduced food intake, eating time, weight change, traditional Chinese medicine syndrome effect, single symptom effect, and trace element Zn recovery rate between the two groups. Based on the non-inferiority test, the experimental group was not inferior to the control group in efficacy. How-ever, the effect of CCEC in reducing appetite in children with anorexia was better than that of control drugs(P<0.05). There was no statistical difference in the incidence of adverse events and adverse reactions between the two groups during the trial. This experiment confirmed the efficacy and safety of CCEC in the treatment of children's anorexia(spleen-stomach disharmony), with a safety and re-liability in clinical application. In addition, it was a better choice for children with anorexia who were mainly manifested by reduced appetite. Meanwhile, compared with granule, chewable tablets were more convenient to take in clinic. Therefore, the efficacy and safety of CCEC for the treatment of children's anorexia(spleen-stomach disharmony) were not inferior to those of Erpixing Granules, with a safety and reliability in clnic. However, due to the small sample size of this trial, the efficacy results only show a trend. It is suggested to further carry out a large-sample-size clinical study to define the clinical advantages of CCEC.

ABSTRACT

Objective:The aim of the present study was to observe the effects of liralutide on body composition and muscle function in adult obese patients with type 2 diabetes.Method:A total of 63 adult obese type 2 diabetic patients who were (52.6±9.7) years of age and with body mass index (BMI) of ≥28 kg/m 2 were enrolled. The patients were randomly assigned into two groups. On the basis of maintaining the original hypoglycemic regimen, patients in the control group ( n=24) were given dietary guidance only, and those in the treatment group ( n=39) were injected with liraglutide. All patients were followed up for a period of 12 weeks. Blood glucose, glycosylated hemoglobin(HbA1c) and insulin levels, liver and kidney function, body composition assessed with electrical impedance methods, and grip strength measured by a grip meter for muscle function were detected at the baseline and the end of the study. Results:Compared with those in the control group, the reductions in HbA1c [(-1.54±2.10) % vs.(-0.53±0.84) %], body weight [(-3.46±4.2) kg vs.(-0.34±3.66) kg], body fat mass [(-1.97±2.98) kg vs.(-0.01±2.16) kg] and visceral fat area [(-0.01±2.16) cm 2 vs.(0.34±6.39) cm 2] were more pronouced in liraglutide treated group (all P<0.05). However, no changes could be observed in muscle mass and grip strength after liraglutide treatment. Conclusions:In addition to reducing blood glucose, body weight and fat mass, treatment with lilaluptide had no impact on muscle mass and muscle function. Therefore, liralutide is suitable for obese patients with type 2 diabetes, especially for weight management patients who are at risk of muscle loss.

ABSTRACT

Objective:To analyze the prevalence of malnutrition in stable-phase elderly patients with chronic obstructive pulmonary disease (COPD) using the Global Leadership Initiative on Malnutrition (GLIM) criteria.Methods:Using cross-sectional survey, 60 elderly patients with COPD in stable phase were investigated, with 72 elderly patients without COPD in the same age group selected as controls. Differences in basic characteristics, anthropometric indicators, hematology indicators and body composition were compared between the two groups. According to the GLIM diagnostic criteria for malnutrition, the first step is nutritional risk screening, the second step is to diagnose malnutrition, and the third step is to determine severe malnutrition. The prevalence of malnutrition and severe malnutrition were investigated.Results:The levels of total protein, albumin, creatinine, and lymphocyte percentage in the elderly stable COPD group were significantly lower than those in the control group. The nutritional risk and the prevalence of malnutrition in elderly COPD patients were significantly higher than those in the control group, and the prevalence of severe malnutrition was higher .Conclusions:Elderly stable COPD patients of different age groups have a higher nutritional risk. The onset age of malnutrition is younger than that of non-COPD patients and early intervention is required.

ABSTRACT

Objective:To investigate the predictive value of dynamic platelet and hemagglutination-related parameters in patients with acute pancreatitis (AP).Methods:The patients admitted to the Department of Emergency Surgery in the First Affiliated Hospital of Zhengzhou University from January 2020 to December 2020 were analyzed. According to the inclusion criteria and exclusion criteria, patients with AP were retrospectively enrolled. According to the Chinese Guidelines for the Diagnosis and Treatment of Acute Pancreatitis (Shenyang, 2019), the patients were divided into two groups: severe acute pancreatitis (SAP group) and non-severe acute pancreatitis (non-SAP group) [including mild acute pancreatitis (MAP) and moderate severe acute pancreatitis (MSAP)]. A normal distribution of the maximum and mean aggregation rates of dynamic platelets (arachiidonic acid), plateletcrit (PCT) and bedside index for severity in acute pancreatitis (BISAP) scores and other measurement data were tested by t test, while measurement data of prothrombin time (PT), fibrinogen (FIB) and D-dimer that did not conform to normal distribution were tested by Mann-Whitney U test. χ 2 test was used for the counting data such as sex, age and etiology of patients in the two groups. The prognostic value of statistically significant indicators for non-SAP group and SAP group was further analyzed by receiver operating characteristic (ROC) curve. Results:A total of 146 patients with AP were enrolled, including 50 patients in SAP group and 96 in non-SAP group. The maximum and average aggregation rates of dynamic platelet (aracidonic acid) in the SAP group were (71.76±17.62) % and (67.91±18.10) %, PT (12.02±1.33) s, FIB (4.76±2.08) g/L, D-dimer (3.75±6.04) μg/L, PCT (0.23±0.08) %, and BISAP scores (1.42±1.18), which were all significantly higher than those in the non-SAP group [the maximum and average aggregation rates of dynamic platelet (arachiidonic acid) (46.65±20.11) % and (42.50±20.71) %, PT (11.50±1.51) s and FIB (3.91±1.48) g/L, D-dimer (1.00±1.37) μg/L, PCT (0.19±0.06) %, BISAP scores (0.45±0.66)] (all P<0.05). According to area under the ROC curve, the maximum and average aggregation rates of dynamic platelets (arachiidonic acid) in serum of patients with SAP were 0.83 and 0.82, respectively, and the sensitivities were 0.56 and 0.68, respectively. The specificity was 0.99 and 0.81, respectively, which was better than PT, FIB, D-dimer, PCT and BISAP scores in predicting the severity of AP. Conclusions:The maximum and average aggregation rates of dynamic platelets (arachidonic acid), PT, FIB, D-dimer, PCT and BISAP scores can be used as predictors of the severity of acute pancreatitis. The maximum and average aggregation rates of dynamic platelets (arachiidonic acid) were the best in predicting the severity of AP.

Similarity evaluation system of traditional Chinese medicine fingerprint (2012 edition) was used to establish the fingerprint and generate the control fingerprint. The chemical constituents of Baoyuantang substance benchmark were identified by comparison of standard substances and UPLC-electrospray ionization tandem mass spectrometry (UPLC-ESI-MS/MS) with full information tandem mass spectrometry (MS<sup>E</sup>) and scanning range of <italic>m</italic>/<italic>z</italic> 50-1 200. Result:The similarities of 15 batches of Baoyuantang substance benchmark were above 0.90 by comparing with the control fingerprint. There were 37 common peaks, 22 of which were identified through UPLC-ESI-MS/MS, including liquiritin, violanthin, ginsenoside Rg<sub>1</sub>, ginsenoside Rb<sub>1</sub>, ginsenoside Re and so on. These components were all from Astragali Radix, Ginseng Radix et Rhizoma, Zingiberis Rhizoma Recens and Glycyrrhizae Radix et Rhizoma. Conclusion:This method is accurate, stable and reliable, which will basically reflect the overall chemical composition characteristics of Baoyuantang, and it provides experimental basis for development of the granules of this famous classical formulas.

ABSTRACT

Atopic dermatitis (AD) is closely related to many systemic diseases, such as other allergic diseases, autoimmune diseases, infectious diseases, cardiovascular diseases and mental disorders, and the underlying mechanism is very complex. AD is considered to be a starting point of the allergy march, and affects the occurrence of various allergic diseases such as food allergies, allergic rhinitis and allergic asthma. AD is associated with the occurrence of many autoimmune diseases, decreased incidence of some malignant tumors and low serum levels of vitamin D. AD is not only a potential risk factor for multiple organ infections and osteoporosis, but also increases the risk of cardiovascular diseases, nephrotic syndrome, and skin dryness. In addition, mental disorders such as anxiety and depression are also common complications of AD. To recognize and investigate into the associations between AD and systemic diseases is of great significance for improving the prognosis and quality of life of AD patients.

ABSTRACT

Objective:To investigate the role of macrophage migration inhibitory factor (MIF) in severe acute pancreatitis (SAP) associated lung injury in mice.Methods:Totally 32 mice were randomly divided into 4 groups ( n=8/per group): wild type control group (WT+CON group), wild type SAP group (WT+SAP group), MIF gene knockout control group (KO+CON group), and MIF gene knockout SAP group (KO+SAP group). SAP model was established by intraperitoneal injection of L-arginine (4 mg/g). The expression of serum amylase, IL-6, TNF-α and MIF were detected by ELISA. The pathological changes of pancreatic and lung tissues were observed by HE staining. The expression of IL-6 and TNF-α in lung tissue was detected by immunohistochemistry. The expression of NF-κB in lung tissue was detected by Western blot. For measurement data, t test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups. Results:Compared with the WT+CON group, pathological score of pancreatic and lung injury, serum amylase, TNF-α and IL-6 expression in serum and lung tissues were significantly increased in the WT+SAP group ( P<0.05), while the above indexes were significantly decreased in the KO+SAP group ( P<0.05). In addition, the expression of NF-κB protein in KO+SAP group was significantly lower than that in the WT+SAP group ( P<0.05). Conclusions:MIF gene knockout can alleviate severe acute pancreatitis associated acute lung injury in mice, and its mechanism may be related to NF-κB.

ABSTRACT

Objective:To analyze the internal transcribed spacer(ITS)2 and psbA-trnH sequences of Ziziphora bungeana in 18 different geographic populations,in order to provide reference about evaluation of germplasm resources and analysis of genetic diversity of medicinal plants. Method:Genomic DNAs of the Z. bungeana were extracted by kit method. Polymerase chain reaction(PCR)was used to amplify ITS2 and psbA-trnH interstitial region sequences,bidirectional sequencing,splicing,and constructing Neighbor-joining(NJ) based on Kimura 2-parameter(K2P) model. Result:All of sequences of ITS2 and psbA-trnH of Z. bungeana in different geographic populations showed intraspecific variations. The average ITS2 sequence length of Z. bungeana was 236 bp,9 haplotypes were detected,and the genetic distance was 0-0.022. Z. bungeana of different geographical groups gathered into two branches,10 geographic populations,including XTH3,XTH6 and XTH9,were considered as one branch,while 8 geographic populations, including XTH4,XTH5 and XTH10,were the other branch. In addition to XTH6 that lacked 6 in bp psbA-trnH sequence,all of the other geographic populations had a 355 bp sequence of psbA-trnH,4 haplotypes were detected,and the genetic distance was 0-0.023. 12 geographic populations,such as XTH1,XTH3,XTH4,gathered into one branch,while XTH14,XTH17 and XTH18 gathered into the other branch. NJ tree based on ITS2+psbA-trnH combination sequence showed that Z. bungeana of different geographical populations could be divided into two branches,with 12 geographical populations,like XTH11,XTH12,XTH16 as one branch, and XTH14,XTH17 and XTH18 as the other branch. Conclusion:Near or similar geographical locations of different geographical populations implies relatively short genetic distance and relatively close genetic relationship,which indicates that genetic relationship and genetic diversity of Z. bungeana in different geographical populations are related to geographical locations.
