Research progress and prospects for the use of plant metabolomics in quality evaluation of traditional Chinese medicinal materials / 药学学报

The quality of traditional Chinese medicine has a direct impact on the effectiveness and safety of its use, and is the premise necessary to ensure the healthy development of the traditional Chinese medicine industry. Comprehensive and accurate control and evaluation of the quality of medicinal materials is of great significance to the traditional Chinese medicine industry, but the complexity and dynamics of the chemical composition of medicinal materials makes their quality evaluation a challenge. Plant metabolomics provides an integrated and comprehensive analysis that is consistent with the holistic approach of traditional Chinese medicine. Chemical information therein promotes the establishment of a traceable system and provides new ideas and methods for the quality evaluation of medicinal materials. Plant metabolomics in the quality evaluation of medicinal materials is gradually increasing, and the core is the screening and identification of differential metabolites or specific marker compounds by means of stoichiometry. This study focused on the main factors that affect the quality of medicinal materials, such as origin, environmental adversity, varieties, harvest time, commercial specification and TCM processing. We describe the research progress in plant metabolomics combined with chemometrics analysis for the quality control and evaluation of medicinal materials, summarize existing problems, identify trends, and propose future research directions. Metabolomics plays an increasingly important role in the quality evaluation of medicinal materials, but the absolute qualitative and quantitative information of metabolomics needs to be further developed, and a single 'omics' technique is not sufficient for an in-depth analysis of medicinal value. In the future, standardization of plant metabolomics methods and a more complete database should be actively promoted, and plant metabolomics should be integrated into quality marker exploration. Plant metabolomics will need to be integrated with other 'omics' methods to improve the quality and evaluation system of medicinal materials.

A new anisotane-type sesquiterpene from Anisodus tanguticus / 药学学报

To investigate the chemical constituents of Anisodus tanguticus, silica gel column chromatography, Sephadex LH-20 column chromatography, preparative thin layer chromatography, and semi-preparative HPLC were used to separate and purify the chemical constituents from the extract of A. tanguticus. The planar structure of the isolated compound was identified by HRMS, IR, and 2D NMR experiments. The absolute configuration of the isolated compound was determined by a combination of NOESY, coupling constant, circular dichroism (CD), and transition metal chelate reagent dimolybdenum tetraacetate [Mo2(OAc)4]-induced circular dichroism (ICD) data analysis. A new compound of the anisotane-type sesquiterpene (1) was isolated, which was determined to be (1R,2S,3R,4R,6R,7R,9R)-anisotane-11(13)-ene-3,4,9-triol and named anisotanol F. This is the second report of anisotane-type sesquiterpene, which has previously been reported as a novel sesquiterpenoid skeleton by our research group. Furthermore, the cytotoxicity against HUVECs and inhibitory effect on NO release in LPS-induced RAW264.7 cells of compound 1 were investigated. However, the results showed that it was inactive. Compound 1 is a new compound isolated from A. tanguticus. It belongs to the unusual anisotane-type sesquiterpene. This result enriches the chemical composition of A. tanguticus.

Objective:To observe the clinical efficacy of the modified Buzhong Yiqitang combined with Erxian decoction in treating stress urinary incontinence （SUI） of perimenopausal women due to spleen and kidney Qi deficiency. Method:One hundred and six patients were randomly divided into a control group （52 cases） and an observation group（54 cases）. Patients in both groups received lifestyle intervention and pelvic floor muscle training （PFMT）. On this basis， patients in the observation group were further treated with the modified Buzhong Yiqitang combined with Erxian decoction， 1 bag/day， while those in the control group were provided with Suoquan pills， 6 g/time， 2 times/day， for eight weeks. Following the international consultation on incontinence questionnaire-short form （ICIQ-SF） scoring before and after treatment， the urodynamic parameters such as maximum urinary flow rate （Q_max）， maximum urethral closure pressure （MUCP）， residual urine volume （RUV）， abdominal pressure leakage point pressure （ALPP）， and bladder capacity （BC） were measured. The number of incontinence episodes per 24 h， the degree of urinary incontinence， the amount of 1 h urine leakage， and the spleen and kidney Qi deficiency syndrome score were recorded before and after treatment. The levels of estradiol （E₂）， follicle stimulating hormone （FSH）， pituitary adenylate cyclase activating peptide （PACAP）， and vasoactive intestinal peptide （VIP） were measured before and after treatment. Result:The ICIQ-SF sub-scores of the urinary incontinence frequency， severity， and impact on quality of life as well as the total score in the observation group were all lower than those in the control group （<italic>P</italic><0.01）. Q_max， MUCP， ALPP and BC in the observation group were elevated in contrast to those in control group （<italic>P</italic><0.01）， while the RUV declined （<italic>P</italic><0.01）. Compared with the control group， the observation group exhibited a decreased number of incontinence episodes per 24 h， milder degree of urinary incontinence， reduced amount of 1 h urine leakage， and lower spleen and kidney Qi deficiency syndrome score （<italic>P</italic><0.01）. The E₂， PACAP， and VIP in the observation group were up-regulated as compared with those in the control group （<italic>P</italic><0.01）， whereas the FSH was down-regulated （<italic>P</italic><0.01）. The cure and effective rates of the observation group were （29/50） 58.00% and （47/50）94.00%， respectively， significantly better than （18/48）37.50% and （38/48）79.17% of the control group （<italic>χ</italic>²=4.124， <italic>χ</italic>²=4.683， <italic>P</italic><0.05）. Conclusion:On the basis of the lifestyle intervention and PFMT， the modified Buzhong Yiqitang combined with Erxian decoction obviously alleviates urinary incontinence， adjusts sex hormones， PACAP and VIP， ameliorates urodynamic parameters， and enhances the quality of life of patients with SUI due to spleen and kidney Qi deficiency. The resulting cure and effective rates are superior to those of the positive control.

A preliminary pharmacophylogenetic study of Solanaceae medicinal plants containing tropane alkaloids / 中国中药杂志

The Solanaceae plants distributed in China belong to 105 species and 35 varietas of 24 genera. Some medicinal plants of Solanaceae are rich in tropane alkaloids(TAs), which have significant pharmacological activities. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, pharmacological activities, and biosynthetic pathways of TAs in Solanaceous plants were summarized. Besides, the phylogeny of medicinal plants belonging to Solanaceae was visualized by network diagram. Fourteen genera of Solanaceae plants in China contain TAs and have medical records. TAs mainly exist in Datura, Anisodus, Atropa, Physochlaina, and Hyoscyamus. The TAs-containing species were mainly concentrated in Southwest China, and the content of TAs was closely related to plant distribution area and altitude. The Solanaceae plants containing TAs mainly have antispasmodic, analgesic, antiasthmatic, and antitussive effects. Modern pharmacological studies have proved the central sedative, pupil dilating, glandular secretion-inhibiting, and anti-asthma activities of TAs. These pharmacological activities provide a reasonable explanation for the traditional therapeutic efficacy of tropane drugs. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, and modern pharmacological activities of TAs-containing species in Solanaceae were analyzed for the first time. Based on these data, the genetic relationship of TAs-containing Solanaceae species was preliminarily discussed, which provided a scientific basis for the basic research on TAs-containing solanaceous species and was of great significance for the development of natural medicinal plant resources containing TAs.

Assessment on the Effects of Hepatitis B Prevention and Control Measures in Western China: A Comparison of Three Population-based Serosurveys / 生物医学与环境科学（英文）

Objective@#Despite the remarkable progress in efforts to control disease spread, the nationwide elimination of hepatitis B in China is still hindered by the persistently high rate of hepatitis B virus (HBV) infection in Western China. This study aimed to evaluate the strategy of hepatitis B prevention and control in Western China and identify potential areas and strategies for improvement.@*Methods@#Susceptible population vaccination, health education, professional training of doctors, and other prevention and control measures have been implemented in Wuwei city since 2010. Data were obtained from three representative cross-sectional serosurveys conducted in 2010, 2013, and 2015. The serum samples were subjected to enzyme-linked immunosorbent assays to detect the following seromarkers: HBV surface antigen (HBsAg), antibody against hepatitis B surface antigen (anti-HBs), and antibody against hepatitis B core antigen (anti-HBc). Estimates of variance were determined using Taylor series linearization methods.@*Results@#The three serosurveys revealed decreases in the prevalence of HBsAg (7.19% in 2010 @*Conclusion@#Although vaccine-based prevention and control measures reduced the rate of HBV infection in Wuwei City over time, the hepatitis B infection rate in children younger than 10 years was still higher than the national average level. Therefore, the prevention and control of mother-to-child transmission and the management of the infected should be the focus of future prevention and control work.

Association between KIAA0319 SNPs and risk of dyslexia: a meta-analysis

The aetiology of developmental dyslexia (DD) is complex; although candidate genes have been suggested, the molecular mechanism and risk factors remain unknown. The KIAA0319 gene is functionally related to neuronal migration and axon growth, and several studies have examined associations between KIAA0319 polymorphisms with DD, but the results remain inconsistent. The sample size affects the results of meta-analysis. The aim of this meta-analysis was to clarify the effect of KIAA0319 polymorphisms on dyslexia susceptibility according to the available evidence. All eligible case–control and transmission/disequilibrium test (TDT) studies published until March 2018 were identified by searchingMedline, PubMed, Embase, Web of Science and Chinese Biomedical Database, limited to Chinese and English language papers. Pooled odds ratios and 95% confidence intervals were calculated using STATS package v12.0. A total of 11 related studies, including 3130 cases of dyslexia and 3460 healthy control subjects, as well as four TDT studies with 842 families were included in our meta-analysis. The results indicated that the polymorphisms rs4504469, rs2038137, rs2179515, rs3212236, rs6935076, rs9461045, rs2143340 and rs761100 have no association between the polymorphisms and dyslexia risk. Three subgroup meta-analyseswere performed according to the study design, country and population. The stratified analysis revealed that the KIAA0319 rs4504469 minor allele was a risk allele t in the TDT subgroup, rs3212236 minor allele was a risk allele t in the UK subgroup and rs6935076 minor allele was a risk allele t in the Canada subgroup. Further studies with larger sample sizes that assess gene–gene and gene–environment interactions are required. The sample size of our study is larger than that of the previous studies, and the results are different from those of the previous studies.We have synthesized all the current studies on KIAA0319 and obtained reliable results.

Pyrexia and hemoptysis for eight days in a school-age child / 中国当代儿科杂志

A girl was diagnosed with intravenous immunoglobulin (IVIG)-resistant Kawasaki disease (KD) due to pyrexia and hemoptysis for eight days. The girl was a school-age child with major clinical manifestations of pyrexia, skin rash, enlargement of bilateral cervical lymph nodes, conjunctival hyperaemia, red and cracked lips and strawberry-like tongue, followed by swelling of both hands and feet. Laboratory examination showed significant increases in white blood cell count, platelet count, C-reactive protein, erythrocyte sedimentation rate and liver enzymes, a significant reduction in albumin, and the presence of aseptic pyuria. After the first course of IVIG treatment, the girl still had recurrent pyrexia, with hemoptysis on day 2 after admission, and lung CT showed uneven luminance and patchy shadow. The symptoms were quickly alleviated after the second course of IVIG treatment combined with methylprednisolone and aspirin treatment. KD is a febrile disease characterized by multiple systemic vasculitis in childhood and can involve various organ systems such as the heart, lungs, kidneys and the nervous system. Therefore, it is necessary to carefully monitor and recognize the rare symptoms of KD, and early recognition of pulmonary complications of KD can avoid delay in diagnosis, prevent the development of more serious complications, and help with early treatment and disease recovery.

Short-term effectiveness of single-level lsobar TTL dynamic internal fixation in the treatment of lumbar degenerative diseases / 中国组织工程研究

BACKGROUND: The short-term effects of dynamic internal fixation and whether dynamic internal fixation system can prevent or delay the process of adjacent level degeneration after lumbar surgery remain in controversy.OBJECTIVE: To investigate the short-term clinical effectiveness of single-level Isobar TTL dynamic internal fixation in the treatment of degenerative lumbar diseases. METHODS: Data of 20 patients who suffered from lumbar degenerative diseases and underwent posterior decompression combined with single-level Isobar TTL dynamic internal fixation, including 11 male patients and 9 female patients, were retrospectively analyzed; the average age of these patients was 47.4 (35-62) years old. Visual analog scale, Japanese Orthopaedic Association scores and Oswestry disability index were used to assess clinical outcomes. Disc height, range of motion, and University of California at Los Angeles Grading Scale were measured on X-ray films to evaluate the status of disc degeneration on both dynamic fixed segment (index segment) and superior adjacent segment. RESULTS AND CONCLUSION: All follow-up patients successfully completed the operation. The average follow-up time was 14.4 (12-27) months. No blood vessels, nerve injury, loose internal fixation or rupture occurred. At the last follow-up, Visual Analog Scale, Japanese Orthopaedic Association scores and Oswestry Disability Index were significantly improved (P < 0.05); range of motion of dynamic fixation segment reduced (P < 0.05) as compared with that before surgery. Intervertebral height of dynamic fixation segments and University of California at Los Angeles Grading Scale classification were not significantly different between follow-up and before surgery (P > 0.05). Intervertebral height of superior adjacent segment, intervertebral range of motion and University of California at Los Angeles Grading Scale classification were not significantly different (P > 0.05). These results indicate that single-level Isobar TTL dynamic internal fixation proved to have satisfactory clinical outcomes in the treatment of lumbar degenerative diseases. During follow-up, disc degeneration on either index segment or superior adjacent segment is not accelerated.

Aim To establish a rapid method to efficiently iso-late mononuclear cells from central nervous system ( CNS) tis-sues of mice that can be effectively utilized for identification of various immune cell populations in a single sample by flow cy-tometry. Methods For defining the feasibility and practicality of the method, wild-type C57BL/6 mice and two mouse models of CNS disease including EAE mice and APP/PS1 mice were used in this study. After the collection and homogenization of the brain and spinal cord tissues respectively, the mononuclear cells were isolated by spinning the 70% -30% Percoll gradients. Cell activities were detected by trypan blue staining, and the im-mune population that infiltrated CNS was identified by flow cy-tometry. Results The results of trypan blue staining showed that the survival rate of the isolated cells was above 90% in all groups. Flow cytometry analysis showed that the relative num- bers of lymphocytes infiltrating CNS of EAE and AD mice in-creased significantly compared with wild-type C57BL/6 mice. In addition, the relative numbers of Th1 and Th17 cell subsets me-diating the inflammatory response also increased significantly, while the decreased regulatory T cells frequency was observed in the two mouse models of CNS disease. Conclusions The cells isolated by the 70% ~30% Percoll gradients centrifugation can be effectively utilized for the identification of various immune cell populations in a single sample by flow cytometry. The meth-od described in this article is simple and rapid in operation and with high survival rate and activity of the cells, which can be ap-plied to the study of the mononuclear cells in CNS.
