Identification and expression analysis of flavonoid O-methyltransferases gene family in Artemisia argyi / 药学学报

italic>Artemisia argyi (A. argyi) is a Chinese herbal medicine in China. The main active components are volatile oils, flavonoids, and other compounds, which have various pharmacological activities. Methoxylated flavonoids are the main active ingredients in A. argyi. Flavonoid O-methyltransferase (FOMT) is a key enzyme in the O-methylation of flavonoids. In order to further understand the function and characteristics of FOMT proteins, this paper carried out the whole genome mining and identification of FOMT genes in A. argyi and performed phylogenetic, chromosomal localization, gene sequence characterization, subcellular localization prediction, protein structure, gene structure analysis, and expression pattern analysis. The results showed that a total of 83 FOMT genes were identified in the genome of A. argyi. The phylogenetic tree shows that FOMT genes are divided into two subgroups, CCoAOMT (caffeoyl CoA O-methyltransferase) subfamily (32 genes) and COMT (caffeic acid O-methyltransferase) subfamily (51 genes). Gene sequence analysis showed that the number of amino acids encoded by FOMT was 70-734 aa, the molecular weight was 25 296.55-34 241.3 Da, and the isoelectric point was 4.51-9.99. Compared with 32 members of the CCoAOMT subfamily, nearly 1/3 of the 51 members of the COMT subfamily were hydrophobic proteins and 2/3 were hydrophilic proteins. Subcellular localization prediction showed that more than 80% of CCoAOMT subfamily members were located in the cytoplasm, and 96% of COMT subfamily members were located in the chloroplast. COMT subfamily members have more motifs than CCoAOMT subfamily members. The N-terminal motifs of COMT subfamily proteins are relatively variable, while the C-terminal motifs are relatively conserved. Expression pattern analysis showed that CCoAOMT subfamily members were mainly expressed in roots, while COMT members were mainly expressed in leaves. Some FOMTs showed the tissue expression specificity by real-time quantitative PCR analysis, especially in leaves. In this study, we identified and analyzed the FOMT gene family in A. argyi, and provided a theoretical basis for further research on the function of FOMTs and the biosynthesis of methylated flavonoids in A. argyi.

Significance of high expression of C5orf46 in gastric cancer and potential intervention of tarditional Chinese medicine based on bioinformatics, molecular docking, and cell experiments / 中国中药杂志

This study aims to investigate the expression, prognosis, and clinical significance of C5orf46 in gastric cancer and to study the interaction between the active components of C5orf46 and tarditional Chinese medicine. The ggplot2 package was utilized for differential expression analysis of C5orf46 in gastric cancer tissues and normal tissues. The survival package was used for survival analysis, univariate regression analysis, and multivariate regression analysis. Nomogram analysis was used to assess the connection between C5orf46 expression in gastric cancer and overall survival. The abundance of tumor-infiltrating lymphocytes was calculated by GSVA package. Coremine database, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) database, and PubChem database were used to search the potential components corresponding to C5orf46 gene and tarditional Chinese medicine. Molecular docking was performed to explore the binding affinity of potential components to C5orf46. Cell experiments were performed to explore the expression of C5orf46 gene in cells of the blank group, model group, and drug administration groups. As compared with normal tissues, C5orf46 expression was higher in gastric cancer tissues, which had more significant predictive effects in the early stages(T2, N0, and M0). The more advanced the tumor node metastasis(TNM) stage, the higher the C5orf46 expression and the lower the probability of survival of patients with gastric cancer. The expression of C5orf46 positively correlated with the helper T cells1 in gastric cancer and the macrophage infiltration level in gastric cancer, and negatively correlated with B cells, central memory T cells, helper T cells 17, and follicular helper T cells. Seven potential components of C5orf46 were obtained, and three active components were obtained after the screening, which matched five tarditional Chinese medicines, namely, Sojae Semen Nigrum, Jujubae Fructus, Trichosanthis Fructus, Silybi Fructus, and Bambusae Concretio Silicea. Molecular docking revealed that sialic acid and adeno-sine monophosphate(AMP) had a good binding ability to C5orf46. The results of real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot showed that, as compared with the model group, the mRNA and protein expression levels of C5orf46 were significantly lower in the drug administration groups. The lowest expression level was found at the concentration of 40 μmol·L~(-1). The results of this study provide ideas for the clinical development of traditional Chinese medicine compounds for the treatment of gastric cancer as well as other cancers.

Phylogenetic analysis of chloroplast genome of Tussilago farfara L / 药学学报

italic>Tussilago farfara L. is a perennial herb of Tussilago genus in the Compositae family. Its dried buds and leaves have good biological activities and have a long history of medicinal use in China and Europe. In this paper, we investigated the whole chloroplast genome characteristics, sequence duplication, structural variation and phylogeny of the Tussilago farfara L. After sequencing the Tussilago farfara L. chloroplast genome using Illumination technology, the complete Tussilago farfara L. chloroplast genome was further obtained by assembly and annotation, followed by a series of inverted repeat-large single copy/small single copy region contraction and expansion analysis, genome sequence variation, etc. The sequences of 13 homologous plants downloaded from NCBI were used to construct a neighbor-joining phylogenetic tree. The results showed that the total GC content of the chloroplast genome was 37.4% and the length was 150 300 bp; 125 genes were annotated, including 82 protein-coding genes, 35 tRNAs and 8 rRNAs; 148 (simple sequence repeats, SSR) loci were detected, and the relative synonymous codon usage showed that 31 codons out of 64 codons had a usage of >1. In the phylogenetic analysis, the chloroplast genomes of the seven species of Asteraceae, including the Yulin Tussilago farfara L., were highly conserved, and the sequence variation of the (large single-copy, LSC) and (small single-copy, SSC) regions was higher than that of the (inverted repeat, IR) region. This is in general agreement with the reported phylogeny of Yulin Tussilago farfara L. In this study, we obtained a high quality chloroplast genome and analyzed its genome characteristics, codon preference, SSR characteristics, SC/IR boundary, sequence variation and phylogeny, which can provide a basis for species identification, genetic diversity analysis and resource development of this medicinal plant.

Effect of electroacupuncture at different time points on the recovery of gastrointestinal function after surgery for gastrointestinal malignant neoplasms / 针灸推拿医学（英文版）

Objective: To observe the effect of electroacupuncture (EA) at different time points during the perioperative period on the recovery of gastrointestinal function after gastrointestinal malignant neoplasms surgery. Methods: Sixty-three patients who needed radical surgery for gastrointestinal tumors were randomized into a control group, treatment group 1 (postoperative EA group), and treatment group 2 (intraoperative and postoperative EA group). The control group received surgery and conventional Western medicine treatment, and treatment groups 1 and 2 received additional EA treatment at different time points. The initial flatus time after the surgery, visual analog scale (VAS) score at different time points after the surgery, the proportion of using patient-controlled analgesia (PCA) after the surgery, and the times of adding analgesics were observed in the three groups. Results: The initial flatus time after the surgery was earlier in treatment groups 1 and 2 than in the control group (P<0.05); the difference between treatment groups 1 and 2 was statistically insignificant (P>0.05). The VAS score was lower in treatment group 2 than in the control group at 6, 12, 24, and 72 h after the surgery (P<0.05); the VAS score was lower in treatment group 1 than in the control group only at 72 h after the surgery (P<0.05). There were no significant differences in the rate of using PCA among the three groups (P>0.05). Regarding the times of adding analgesics, it was less in treatment group 2 than in the control group at 12 h after the surgery (P<0.05). Conclusion: Either EA during and after the surgery or only after the surgery can hasten the initial flatus and boost the recovery of gastrointestinal function in patients after radical resection of gastrointestinal neoplasms. Successive EA during and after the surgery should be superior to postoperative EA regarding the analgesic effect after the surgery.

Historical Review About 60 Years' Clinical Practice of Acupuncture Anesthesia / 针刺研究

Acupuncture anesthesia (AA) is an anesthetic method created by medical workers and researchers in China during medical practice in 1950s. As a paragon of integrated traditional Chinese and Western medicine, AA clinical practice and basic theoretic research have gained continuous improvement and progress, and obtained a series of outstanding achievements in the past 60 years. Consequently, the theory of traditional Chinese medicine was enriched, and the acupuncture therapy was pushed forward to the world. The present paper reviews the course of formation and development of clinical application of AA from the late years of 1950s up to now, including the initial stage (1958-1966), rapid propulsion stage (1967-1979), consolidation period (1980-2004) and newly developing period (2005-now). The AA has experienced flexural pathway from simple acupuncture analgesia, to acupuncture-drug compound anesthesia (or acupuncture-assisted anesthesia), and to the application of whole perioperative period. Nowadays, it keeps unceasing development and innovation from simple analgesia and sedation to organ protection during perioperative period and reduction of post-operative complications. The AA possesses unique prosperous vitality, and also has a plenty room for improvement, being worthy of further popularization and research.

Research progress on antidepressant effects of Sini San based on three progressive levels of "single herb, herb-pair, and complicated Chinese herbal formula" / 中国中药杂志

Depression is a kind of mental illness accompanied by complex etiology and pathogenesis in clinic. With the quickening pace of circadian rhythm and increase of life pressure in modern society, the incidence of depression is increasing year by year. Nowadays, some typical antidepressant Western medicines, such as selective serotonin re-uptake inhibitors (SSRI) and tricyclic antidepressants (TCA), have been used as the main therapeutic drugs in clinic. Unfortunately, administration of these drugs will result in severe adverse reactions, slow treatments, and low cure rates, thus obviously they can not be used for a long term. Sini San, which originated from written by Zhang zhongjing, is a prescription widely applied in clinic for curing mental illness and also a basic Chinese herbal formula for modern treatment of depression. This article would review the research progress on antidepressant effects of Sini San based on single herbs of Bupleuri Radix and Paeoniae Radix Alba, herb-pair of Bupleuri Radix-Paeoniae Radix Alba, and formula of Sini San, providing directions and ideas for future research on complicated Chinese herbal formulae.

Modification of 6 Hz corneal kindled mouse model for drug-resistant epilepsy and its treatment by three traditional Chinese medicine prescriptions / 药学学报

Drug-resistance is a challenge in the treatment of epilepsy, and traditional Chinese medicine (TCM) prescription may have a potential in therapy of the epilepsy. Here we established a modified 6 Hz corneal kindled mouse model of epilepsy, and verified its drug-resistance to four commonly used western medicines. We evaluated the efficacy of three classical TCM prescriptions in this drug-resistant epilepsy model. The results showed that:① most C57BL/6J mice with stimulation current intensity at 44 mA (8 out of 10) were fully kindled, while none ICR mice with stimulation current intensity at 44 mA or C57BL/6J mice with stimulation current intensity at 24 mA were fully kindled. Fully kindled mice exhibited epileptic electroencephalograms after 44 mA and 6 Hz corneal kindling stimulation and increased activation of astrocytes in the hippocampus (by staining the glial fibrillary acidic protein); ② 50 mg·kg-1 phenytoin sodium, 100 mg·kg-1 valproic acid sodium and 15 mg·kg-1 lamotrigine had no significant effects on the drug-resistant seizures in 6 Hz corneal kindled C57BL/6J mice, while 100 mg·kg-1 levetiracetam significantly reduced the seizure stage (P P -1) and Tian-Ma Gou-Teng decoction (14.82 or 44.46 g·kg-1), had no significant effects on the drug-resistant seizures in 6 Hz corneal kindled C57BL/6J mice, while TCM prescription Feng-Yin decoction (19.11 g·kg-1) significantly reduced both the seizure stage (P P < 0.05) in it. Thus, the modified 6 Hz corneal kindled C57BL/6J mouse model is an excellent drug-resistant epilepsy model, Feng-Yin decoction have antiepileptic effects on it, suggesting Feng-Yin decoction may be an effective TCM prescription for clinical treatment of drug-resistant epilepsy.

Coronary arteriography under acupuncture anesthesia:a case report / 针灸推拿医学（英文版）

Acupuncture anesthesia is a technique by partially or completely replacing anesthetics with acupuncture in surgery based on the traditional acupuncture analgesia mechanism.It emerged in the 1950s,went viral in the 1970s and then gradually fell into decline.In the recent years,this technique has regained attention and further research.Acupuncture anesthesia can be classified as either pure acupuncture anesthesia or acupuncture-medication combined anesthesia.To expand the application of this technique,a patient with non-ST elevation acute coronary syndrome in urgent need of percutaneous coronary intervention (PCI) received pure acupuncture anesthesia because of an allergy to lidocaine,and the operation went successfully.This is the first time that pure acupuncture anesthesia and coronary arteriography were combined,which is of great significance in further study and development of acupuncture anesthesia.

The safety and efficacy of transarterial chemoembolization combined with sorafenib and sorafenib mono-therapy in patients with BCLC stage B/C hepatocellular carcinoma.

BACKGROUND: Sorafenib and transarterial chemoembolization (TACE) are recommended therapies for advanced hepatocellular carcinoma (HCC), but their combined efficacy remains unclear. METHODS: Between August 2004 and November 2014, 104 patients with BCLC stage B/C HCC were enrolled at the Affiliated Tumor Hospital of Guangxi Medical University, China. Forty-eight patients were treated with sorafenib alone (sorafenib group) and 56 with TACE plus sorafenib (TACE + sorafenib group). Baseline demographic/clinical data were collected. The primary outcomes were median overall survival (OS) and progression-free survival (PFS). Secondary outcomes were overall response rate (ORR) and sorafenib-related adverse events (AEs). Baseline characteristics associated with disease prognosis were identified using multivariate Cox hazards regression. RESULTS: The mean age of the 104 patients (94 males; 90.38%) was 49.02 ± 12.29 years. Of the baseline data, only albumin level (P = 0.028) and Child-Pugh class (P = 0.017) differed significantly between groups. Median OS did not differ significantly between the sorafenib and TACE + sorafenib groups (18.0 vs. 22.0 months, P = 0.223). Median PFS was significantly shorter in the sorafenib group than that in the TACE + sorafenib group (6.0 vs. 8.0 months, P = 0.004). Six months after treatments, the ORRs were similar between the sorafenib and TACE + sorafenib groups (12.50% vs. 18.75%, P = 0.425). The rates of grade III-IV adverse events in sorafenib and TACE + sorafenib groups were 29.2% vs. 23.2%, respectively. TACE plus sorafenib treatment (HR = 0.498, 95% CI = 0.278-0.892), no vascular invasion (HR = 0.354, 95% CI = 0.183-0.685) and Child-Pugh class A (HR = 0.308, 95% CI = 0.141-0.674) were significantly associated with better OS, while a larger tumor number was predictive of poorer OS (HR = 1.286, 95% CI = 1.031-1.604). TACE plus sorafenib treatment (HR = 0.461, 95% CI = 0.273-0.780) and no vascular invasion (HR = 0.557, 95% CI = 0.314-0.988) were significantly associated with better PFS. CONCLUSIONS: Compared with sorafenib alone, combining TACE with sorafenib might prolong survival and delay disease progression in patients with advanced HCC.

Effects of Zn, macronutrients, and their interactions through foliar applications on winter wheat grain nutritional quality.

Although application of Zn combined with macronutrients (K, P, and N) can be used to fortify wheat grain with Zn, little is known about their interactions when foliar application is employed or the influences of common soil fertility management practices (e.g. N and straw management) on their efficiency. Therefore, the effects of foliar-applied Zn and N, P, or K on grain nutritional quality (especially Zn) were investigated in wheat grown under different soil N rates at two sites with (Sanyuan) or without (Yangling) employing straw return. A 4-year-long field experiment was also conducted to evaluate the environmental stability of the foliar formulations. Across 6 site-years, foliar Zn application alone or combined with N, P, or K fertilizers resulted in 95.7%, 101%, 67.9% and 121% increases in grain Zn concentration, respectively. In terms of increasing grain Zn concentration, foliar-applied Zn positively interacted with N (at Sanyuan) and K (at Yangling), but negatively interacted with P at any condition tested, suggesting depressive effects of foliarly-applied P on physiological availability of Zn. Although these interaction effects were the major factor that governing the efficiency of foliar-applied Zn combined with N, P, or K on grain Zn concentration, the magnitude of the increase/decrease in grain Zn (-3.96~5.71 mg kg-1) due to these interactions was much less than the average increases following Zn+K (31.3), Zn+P (18.7), and Zn+N (26.5 mg kg-1) treatments relative to that observed in foliar Zn-only treatment. The combined foliar application of Zn with N, P, or K did not cause any adverse impact on grain yield and other nutritional quality and in some cases slightly increased grain yield and macronutrient concentrations. Grain phytic acid:Zn molar ratios were respectively 52.0%, 53.1%, 43.4% and 63.5% lower in the foliar Zn, Zn+N, Zn+P and Zn+K treatments than in the control treatment. These effects were consistent over four years and across three soil N rates. Overall, combined foliar application of Zn with N, P, or K can successfully fortify wheat grain with Zn (above 40 mg kg-1), and including Zn in foliar N or K application are preferred for practically increasing dietary Zn intake.

Comprehensive treatments for hepatocellular carcinoma with tumor thrombus in major portal vein.

AIM: To evaluate the efficacy of transcatheter arterial chemoembolisation (TACE) compared with surgical intervention and sorafenib for treatment of hepatocellular carcinoma (HCC) in patients with tumor thrombus extending to the main portal vein. METHODS: From 2009 to 2013, a total of 418 HCC patients with tumor thrombus extending to the main portal vein were enrolled in this study and divided into four groups. These groups underwent different treatments as follows: TACE (n = 307), surgical intervention (n = 54), sorafenib (n = 15) and palliative treatment (n = 42). Overall survival rates were determined by Kaplan-Meier method, and differences between the groups were identified through log-rank analysis. Cox's proportional hazard model was used to identify the risk factors for survival. RESULTS: The mean survival periods for patients in the TACE, surgical intervention, sorafenib and palliative treatment groups were 10.39, 4.13, 5.54 and 2.82 mo, respectively. For the TACE group, the 3-, 6-, 12- and 24-mo survival rates were 94.1%, 85.9%, 51.5% and 0.0%, respectively. The corresponding rates were 60.3%, 22.2%, 0.0% and 0.0% for the surgical intervention group and 50.9%, 29.5%, 0.0% and 0.0% for the sorafenib group. Evidently, the results in the TACE group were significantly higher than those in the other groups (P < 0.0001). Furthermore, no significant difference among survival rates was observed between TACE with/without sorafenib (10.22 mo vs 10.52 mo, P = 0.615). No significant difference in survival rates was also found among the surgical intervention, sorafenib and palliative treatment groups (P > 0.05). These values significantly increased after TACE with/without sorafenib compared with other treatments (P < 0.05). CONCLUSION: For HCC patients with tumor thrombus extending to the main portal vein, TACE can yield a higher survival rate than surgical intervention or sorafenib treatment.

[Effects of straw returning combined with medium and microelements application on soil organic carbon sequestration in cropland.] / ç§¸ç§†è¿˜ç”°é æ–½ä¸­å¾®é‡å ƒç´ å¯¹å†œç”°åœŸå£¤æœ‰æœºç¢³å›ºæŒçš„å½±å“.

A 52-day incubation experiment was conducted to investigate the effects of maize straw decomposition with combined medium element (S) and microelements (Fe and Zn) application on arable soil organic carbon sequestration. During the straw decomposition, the soil microbial biomass carbon (MBC) content and CO2-C mineralization rate increased with the addition of S, Fe and Zn, respectively. Also, the cumulative CO2-C efflux after 52-day laboratory incubation significantly increased in the treatments with S, or Fe, or Zn addition, while there was no significant reduction of soil organic carbon content in the treatments. In addition, Fe or Zn application increased the inert C pools and their proportion, and apparent balance of soil organic carbon, indicating a promoting effect of Fe or Zn addition on soil organic carbon sequestration. In contrast, S addition decreased the proportion of inert C pools and apparent balance of soil organic carbon, indicating an adverse effect of S addition on soil organic carbon sequestration. The results suggested that when nitrogen and phosphorus fertilizers were applied, inclusion of S, or Fe, or Zn in straw incorporation could promote soil organic carbon mineralization process, while organic carbon sequestration was favored by Fe or Zn addition, but not by S addition.
