[Distinguishing between Artemisia stolonifera and A. argyi by specific PCR of leaves and non-glandular trichomes].

Artemisia stolonifera is a relative of A. argyi. The two species are difficult to be distinguished due to the similarity in leaf shape and have even less distinctive features after processing. This study aims to establish a method to quickly distinguish between them. At the same time, we examined the reasonability and applicability of the specific polymerase chain reaction(PCR) method. The C/T single nucleotide polymorphism was detected at the position 202 of the sequence, based on which specific primers were designed to identify these two species. The PCR with the specific primer JNC-F and the universal primer ITS3R produced a specific band at 218 bp for A. argyi and no band for A. stolonifera, which can be used to detect at least 3% of A. argyi samples mixed in A. stolonifera samples. The PCR with the specific primer KY-F and the universal primer ITS3R produced a specific band at 218 bp for A. stolonifera and no band for A. argyi, which can be used to detect at least 5% of A. stolonifera samples mixed with A. argyi. The limit of detection of the established method was 5 ng DNA. The established PCR method can accurately distinguish between A. stolonifera and A. argyi, which provides an experimental basis for the quality control of A. stolonifera and determines whether the herbs are adulterated.

[Identification, biological characteristics, and screening of effective fungicides of Phoma rhei causing leaf spot on Polygonum cuspidatum].

Severe leaf spot on Polygonum cuspidatum was found in the planting base of P. cuspidatum in Fangxian county, Shiyan of Hubei province. To clarify the types of pathogens and their pathogenesis, the present study isolated and purified the pathogen of leaf spot disease of P. cuspidatum according to Koch's postulates, determined the pathogenicity of the pathogen, and investigated its biological characteristics. Meanwhile, the inhibitory effects of 11 types of fungicides on the bacteria were determined according to the mycelium growth rate, and suitable prevention and control drugs were selected. The results showed that the pathogen isolated from the diseased leaves of P. cuspidatum was Phoma rhei by morphological and molecular identification. The colony morphology and microscopic characteristics were the same as those of Ph. rhei. The homology of rDNA-ITS and TEF gene sequences with Ph. rhei reached 99.96% and 99.43%, respectively. The optimal growth temperature of Ph. rhei was 25 ℃, and the optimal pH was 7-10. Furthermore, Ph. rhei grew faster under dark or light conditions. In fungicides, 0.3% eugenol, 250 g·L~(-1) propiconazole, and 33.5% quinoline copper had significant inhibitory effects on the pathogen with EC_(50) values of 57.54, 59.58, 88.69 µg·mL~(-1), respectively. Eugenol is a botanical fungicide, which can be used as a green and environmentally friendly fungicide in the prevention and control of P. cuspidatum. This study reported for the first time that the pathogen of P. cuspidatum leaf spot was Ph. rhei. investigated the biological characteristics of the pathogen, and screened the indoor chemicals, which provided a theoretical basis for the prevention and control of P. cuspidatum leaf spot in production.

[Establishment of HPLC fingerprint and comparison of active ingredients between varieties of chrysanthemum in Hubei province].

In this paper,the fingerprint of different varieties of chrysanthemum were established with " Similarity Evaluation System for Chromatographic Fingerprint of Chinese Materia Medica" and the content of chlorogenic acid,galuteolin and 3,5-O-dicaffeoylquinic acid in 29 batches of different varieties of chrysanthemum in Futianhe town,Huangtugang town and Wuhan city were compared. At the same time,similarity evaluation and common peak clustering analysis were carried out. There were 11 common peaks in the fingerprints of 29 batches of different varieties of chrysanthemum,and the similarity ranged from 0. 802 to 0. 975.

Based on the contents of three active ingredients and the diversity of fingerprint peaks,the quality of the characteristic germplasm resource of local Fubaijuin Macheng is superior,and the protection of local characteristic germplasm resource should be strengthened in production.

[Effects of fresh-cut on drying rate and quality of Panax notoginseng].

To study the effects of fresh-cut drying methods on the appearance and internal components of Panax notoginseng, and explore the feasibility of fresh-cut drying methods of P. notoginseng, so as to provide more effective processing methods for the production of P. notoginseng slices and Chinese patent medicines. In this study, we have compared the effects of 6 different drying methods on drying time, drying rate, density, appearance and internal components of P. notoginseng roots. It takes about 453 h to dry by whole-root drying in the sun, with a long constant speed period and a slow drying rate, the time of whole-root drying at 50 ℃ was shortened by 61.6% compared with whole-root drying in the sun, which resulted in the decrease of density and poor appearance of the medicinal material with hollow and crack appeared in the xylem, while the drying time of fresh-cut drying method was reduced by 61.82% to 91.58% and the drying rate increased greatly, due to the relatively slow drying process in the sun or in the shade after fresh-cut, salting-out and whitening appeared on the surface, and the internal components were all decreased to some extent. The drying time of fresh-cut drying at 50 ℃ was 91.58% and 68.83% shorter than that of whole-root drying in the sun and at 50 ℃, respectively. When drying at 50 ℃ after fresh-cut, the appearance and content of internal components of the medicinal materials were better, the appearance was yellowish green, the cut sections were clear with uniform pore distribution, and the content of saponin components was increased by 7.24% compared with that of the whole-root drying at 50 ℃, When drying at 40 ℃, the surface of slices has salting-out and whitening spots, and the loss of dencichine and total sugar was large, but at 60 ℃, this high temperature made the rate of dehydration of slices was extremely fast, which led to severe cracking and fragmentation, and the loss of total sugar and alcohol extract was large. By vacuum freeze drying after fresh-cut, the structure of medicinal materials slices was loose, the density was greatly reduced, and the appearance was different from those recorded in traditional books. The contents of total saponin components and dencichine were increased by 16.51% and 22.54%, respectively, compared with traditional whole-root drying. The fresh-cut process method is feasible in the production of P. notoginseng slices. In production, it is recommended that drying at 50 ℃ after fresh-cut can make the medicinal materials better in appearance and content of internal components, which is convenient for the subsequent processing and industrial feeding extraction. For the purpose of internal contents, it is better to adopt freeze-drying after fresh-cut processing method.

Kruppel-like factor 2 inhibit the angiogenesis of cultured human liver sinusoidal endothelial cells through the ERK1/2 signaling pathway.

Kruppel-like factor 2 (KLF2) is a crucial anti-angiogenic factor. However, its precise role in hepatic angiogenesis induced by liver sinusoidal endothelial cells (LSECs) remain unclear. This study was aimed to evaluate the effect of KLF2 on angiogenesis of LSECs and to explore the corresponding mechanism. Cultured human LSECs were infected with different lentiviruses to overexpress or suppress KLF2 expression. The CCK-8 assay, transwell migration assay and tube formation test, were used to investigate the roles of KLF2 in the proliferation, migration and vessel tube formation of LSECs, respectively. The expression and phosphorylation of ERK1/2 were detected by western blot. We discovered that the up-regulation of KLF2 expression dramatically inhibited proliferation, migration and tube formation in treated LSECs. Correspondingly, down-regulation of KLF2 expression significantly promoted proliferation, migration and tube formation in treated LSECs. Additionally, KLF2 inhibited the phosphorylation of ERK1/2 pathway, followed by the function of KLF2 in the angiogenesis of LSECs disrupted. In conclusion, KLF2 suppressed the angiogenesis of LSECs through inhibition of cell proliferation, migration, and vessel tube formation. These functions of KLF2 may be mediated through the ERK1/2 signaling pathway.

The result also showed that the model using Raman spectroscopy and based on an improved siPLS can get a rapid determination for contents of 5 kinds of Traditional Chinese Medicine containing CaCO3.

HER2 mRNA status contributes to the discrepancy between gene amplification and protein overexpression in gastric cancer.

BACKGROUND: Human epidermal growth factor receptor 2 (HER2) is an important proto-oncogene of prognostic use in gastric cancer (GC). Fluorescence in-situ hybridization (FISH) and immunohistochemistry (IHC) are the main clinical methods of detection of HER2, but consistency between the methods is poor and the cause of the discrepancy is unclear. AIM: To investigate the involvement of HER2 mRNA status in the disparity between gene amplification and protein overexpression. METHODS: We investigated HER2 gene, mRNA, and protein profiles in gastric precancer and cancer tissues by use of the molecular approaches FISH, real-time polymerase chain reaction, and IHC. The relationships between HER2 and matrix metalloproteinase 9 (MMP9) and Smad7 expression were analyzed and the involvement of HER2 in the interaction between tumor cells and lymphocytes was investigated by coculturing GC cell lines with peripheral blood mononuclear cells (PBMCs). RESULTS: HER2 protein expression was significantly increased in cancer compared with precancer (P = 0.003), and the corresponding mRNA levels were significantly lower in precancer and cancer tissues than in normal tissues (κ = 0.290, P = 0.025). HER2 mRNA levels were significantly higher in tumor than in peritumor tissue (P = 0.028), and were positively correlated with MMP9 and Smad7 mRNA levels in tumor tissues. HER2 mRNA expression in GC cell lines was increased by coculture with PBMCs. CONCLUSIONS: Different HER2 mRNA profiles, possibly in relation to contact between tumor cells and lymphocytes, might help to explain the discrepancy between gene amplification and protein overexpression results.

The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.

FoxP3 inhibits proliferation and induces apoptosis of gastric cancer cells by activating the apoptotic signaling pathway.

Forkhead Box Protein 3 (FoxP3) was identified as a key transcription factor to the occurring and function of the regulatory T cells (Tregs). However, limited evidence indicated its function in tumor cells. To elucidate the precise roles and underlying molecular mechanism of FoxP3 in gastric cancer (GC), we examined the expression of FoxP3 and the consequences of interfering with FoxP3 gene in human GC cell lines, AGS and MKN45, by multiple cellular and molecular approaches, such as immunofluorescence, gene transfection, CCK-8 assay, clone formation assay, TUNEL assay, Flow cytometry, immunoassay and quantities polymerase chain reaction (PCR). As a result, FoxP3 was expressed both in nucleus and cytoplasm of GC cells. Up-regulation of FoxP3 inhibited cell proliferation and promoted cell apoptosis. Overexpression of FoxP3 increased the protein and mRNA levels of proapoptotic molecules, such as poly ADP-ribose polymerase1 (PARP), caspase-3 and caspase-9, and repressed the expression of antiapoptotic molecules, such as cellular inhibitor of apoptosis-1 (c-IAP1) and the long isoform of B cell leukemia/lymphoma-2 (Bcl-2). Furthermore, silencing of FoxP3 by siRNA in GC cells reduced the expression of proapoptotic genes, such as PARP, caspase-3 and caspase-9. Collectively, our findings identify the novel roles of FoxP3 in inhibiting proliferation and inducing apoptosis in GC cells by regulating apoptotic signaling, which could be a promising therapeutic approach for gastric cancer.

IL-17A/p38 Signaling Pathway Induces Alveolar Epithelial Cell Pyroptosis and Hyperpermeability in Sepsis-Induced Acute Lung Injury by Activating NLRP3 Inflammasome.

Sepsis is a syndrome with poor prognosis. Nucleotide-binding domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasome and T helper 17 (Th17) cells are involved in the pathogenesis of inflammatory diseases. This study aims to explore their roles and underlying mechanisms in sepsis. The blood and bronchoalveolar lavage fluid are collected from sepsis patients and healthy donors. A sepsis mice model is established by cecal ligation puncture (CLP). The contents of cytokines are detected by ELISA. The amounts of Th17 cells, IL-17A, IL-1ß, IL-18, and lipopolysaccharide is significantly elevated in sepsis patients. The increased differentiation of Th17 cells can promote lung cell pyroptosis and induce hyperpermeability via activating NLRP3 inflammasome and p38 pathway. The inhibitors targeting Th17 cells, NLRP3 inflammasome, and p38 pathway can significantly alleviate lung injury in sepsis mice. Th17 cells can secrete IL-17A to activate NLRP3 inflammasome via p38 signaling pathway, which contributes to the development of sepsis-induced acute lung injury.

The immunomodulation role of Th17 and Treg in renal transplantation.

Kidney transplantation (KT) is an ultimate treatment of end-stage chronic kidney disease, which can meet a lot of complications induced by immune system. With under-controlled immunosuppression, the patient will obtain a good prognosis. Otherwise, allograft disfunction will cause severe organ failure and even immune collapse. Acute or chronic allograft dysfunction after KT is related to Th17, Treg, and Th17/Treg to a certain extent. Elevated Th17 levels may lead to acute rejection or chronic allograft dysfunction. Treg mainly plays a protective role on allografts by regulating immune response. The imbalance of the two may further aggravate the balance of immune response and damage the allograft. Controlling Th17 level, improving Treg function and level, and adjusting Th17/Treg ratio may have positive effects on longer allograft survival and better prognosis of receptors.

Decreased expression of retinoblastoma protein-interacting zinc-finger gene 1 in human esophageal squamous cell cancer by DNA methylation.

BACKGROUND: To study the expression of the RIZ1 (Retinoblastoma protein-interacting zinc-finger gene 1) gene and investigate the promoter region methylation status of RIZ1 gene in the human esophageal squamous cell carcinoma (ESCC) cell lines of KYSE150, KYSE510, TE13, EC9706, CaEsl7, and EC109. To investigate the influence of DNMT (DNA methyltransferase) 5-aza-CdR(5-aza-2'-deoxycytidine) on the transcription of the RIZ1 gene in one cell line whose RIZ1 gene promoter region methylation was detected, and to investigate its influence on the cell proliferation. METHODS: Real-time PCR (Real-time quantitative PCR) and an immunohistochemistry technique was used to get the expression of RIZ1 in specimens from 6 human ESCC cell lines and 28 ESCC patients (tumor tissues and adjacent non-cancerous tissues). MSP (Methylation-specific PCR) was used to investigate the promoter region methylation status of the RIZ1 gene in the 6 ESCC cell lines. One cell line, whose RIZ1 gene promoter region methylation was detected, was chosen for the next studies in which it was treated it by with 5-aza-CdR. Real-time PCR was used to investigate its influence on the transcription of RIZ1 gene and MTT (methyl thiazolyl tetrazolium) was used to detect if 5-aza-CdR inhibits the proliferation of the cell line. RESULTS: In the 28 ESCC patient samples, RIZ1 expression was significantly lower in the tumor tissues than that in their adjacent non-cancerous tissues (p < 0.05). Consistently, immunohistochemistry analyses of RIZ1 protein expression showed that in the ESCC tissues RIZ1 protein expression was also significantly lower than in the adjacent tissues. In the human ESCC tissues the rate of expression accounts for 0% (0/12), and in the adjacent noncancerous tissues the rate of expression was 66.7% (8/12), the correlation was highly significant (chi2 = 12.000, p < 0.05). Promoter methylation of the RIZ1 gene was detected in TE13, CaEsl7, EC109. The cell line TE13 was chosen for the next studies. The expression of RIZ1 mRNA in TE-13 was up-regulated after having been treated with 5-aza-CdR. 5-aza-CdR inhibited cell proliferation of TE-13 in a time and concentration-dependent manner. CONCLUSIONS: Promoter methylation may play an important role in the epigenetic silencing of RIZ1 gene expression. Methylation of the RIZ1 promoter and loss of RIZ1 expression in human ESCC are independent biomarkers. Their determination may offer guidance for selecting appropriate diagnoses and treatments. RIZ1 may be a potential tumor suppressor in human ESCC.

METHODS: A total of 60 children with salivation in cerebral palsy were randomized into an observation group and a control group, 30 cases in each group. The observation group was treated with intradermal needling (kept for 24 hours each time at Jiache [ST 6], Dicang [ST 4], tongue three needles, etc. ) and oral motor therapy, while the control group was only given oral motor therapy. The intradermal needling was performed 3 times a week, and oral motor therapy was performed 5 times a week, 4 weeks as a course, totally 3 courses of treatment were required. The classification of teacher drooling scale (TDS), drooling severity and Kubota water swallow test, dysphagia disorders survey (DDS) score were compared before treatment and after 4, 8 and 12 weeks of treatment in both groups, and the clinical efficacy was evaluated. RESULTS: After 8 weeks of treatment in the observation group and after 12 weeks of treatment in the two groups, the classification of TDS and drooling severity were improved (P<0.05), and the observation group was better than the control group after 12 weeks of treatment (P<0.05). After 8 and 12 weeks of treatment, the DDS scores of oral period in the observation group were lower than those before treatment (P<0.05). The total effective rate in the observation group was 83.3% (25/30), which was higher than 53.3% (16/30) in the control group (P<0.05). CONCLUSION: The combination of intradermal needling with oral motor therapy can improve salivation symptoms and swallowing function in children with cerebral palsy, the effect is better than oral motor therapy alone, and the effect is earlier.

Effectiveness of parent-training program on children with autism spectrum disorder in China.

Objective: This study intends to explore the effect of parent-training program on the rehabilitation intervention in children with autism spectrum disorder (ASD) in Chinese-speaking areas of China by offering parent skill training and psychology counseling. Methods: From January 2018 to June 2019, a total of 80 children diagnosed with ASD from the Department of Children Healthcare of Wuxi Children's Hospital were randomly grouped into the parent training groups and control groups. Parents in the training group received 12 weeks of skill training, including 8 group and 2 individual training sessions, as well as psychology counseling. This enabled them to give their children >2 h of intervention training daily in a natural environment. Children in the control group were placed on a rehabilitation waiting list or received general community training. Before grouping and after the intervention, all children underwent neuropsychological evaluations with Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), and Gesell Developmental Schedule (GDS). GDS covers five sectors, namely adaptive behavior, gross motor, fine motor, language, and personal-social behavior. Results: Statistically significant differences were not detected between the two groups in ABC, CARS, and GDS scoring at baseline evaluation. And significant differences were detected between the two groups in ABC, CARS, adaptive behavior, and personal-social behavior scoring at endpoint evaluation. Furthermore, the re-evaluation results of ABC scoring and CARS scoring of the children in the parent training group decreased significantly from the preliminary evaluation results when compared before and after the intervention. Moreover, the intragroup comparison of adaptive behavior scoring, language scoring, and personal-social behavior scoring of the experiment group increased significantly from the preliminary evaluation results, while the difference of the same of the children in the control group between re-evaluation and preliminary evaluation did not differ significantly. Conclusions: In China, the parent-training program enables parents to train ASD children in a natural environment, which would markedly improve behavioral problems, core symptoms, adaptability, language competence, and social development capability.
