Composite Sophora Colon-Soluble Capsule Ameliorates DSS-Induced Ulcerative Colitis in Mice via Gut Microbiota-Derived Butyric Acid and NCR+ ILC3.

OBJECTIVE: To investigate the effects of composite Sophora colon-soluble Capsule (CSCC) on gut microbiota-mediated short-chain fatty acids (SCFAs) production and downstream group 3 innate lymphoid cells (ILC3s) of dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) mice model. METHODS: The main components of CSCC were analyzed by hybrid ultra-high-performance liquid chromatography ion mobility spectromety quadrupole time-of-flight mass spectrometry (UHPLC-IM-QTOF/MS). Twenty-four male BALB/c mice were randomly divided into 4 groups (n=6) by using a computer algorithm-generated random digital, including control, DSS model, mesalazine, and CSCC groups. A DSS-induced colitis mice model was established to determine the effects of CSCC by recording colonic weight, colonic length, index of colonic weight, and histological colonic score. The variations in ILC3s were assessed by immunofluorescence and flow cytometry. The results of gut microbiota and SCFAs were acquired by 16s rDNA and gas chromatography-mass spectrometry (GC-MS) analysis. The expression levels of NCR+ ILC3-, CCR6+ Nkp46- (Lti) ILC3-, and ILCreg-specific markers were detected by enzyme-linked immunosorbent assay, and real-time quantitative polymerase chain reaction and Western blot, respectively. RESULTS: The main components of CSCC were matrine, ammothamnine, Sophora flavescens neoalcohol J, and Sophora oxytol U. After 7 days of treatment, CSCC significantly alleviated colitis by promoting the reproduction of intestinal probiotics manifested as upregulation of the abundance of Bacteroidetes species and specifically the Bacteroidales_S24-7 genus (P<0.05). Among the SCFAs, the content of butyric acid increased the most after CSCC treatment. Meanwhile, compared with the model group, Lti ILC3s and its biomarkers were significantly downregulated and NCR+ ILC3s were significantly elevated in the CSCC group (P<0.01). Further experiments revealed that ILC3s were differentiated from Lti ILC3s to NCR+ ILC3s, resulting in interleukin-22 production which regulates gut epithelial barrier function. CONCLUSION: CSCC may exert a therapeutic effect on UC by improving the gut microbiota, promoting metabolite butyric acid production, and managing the ratio between NCR+ ILC3s and Lti ILC3s.

[Research on anti-tumor natural product diosgenin].

Diosgenin is widely distributed in many plants, such as Polygonatum sibiricum, Paris polyphylla, Dioscorea oppositifolia, Trigonella foenum-graecum, Costus speciosus, Tacca chantrieri, which has good anti-tumor activity and preferable effects on preventing atherosclerosis, protecting the heart, treating diabetes, etc. This review combed through the anti-tumor mechanisms of diosgenin encompassing lung, breast, gallbladder, liver, oral cavity, stomach, bladder, bone marrow, etc. Besides, it was discovered that diosgenin mainly exerts its effect by inhibiting tumor cell migration, suppressing tumor cell proliferation and growth, and inducing cell apoptosis. However, problems like low yield and bioavailability frequently exist in natural diosgenin. This review introduced methods such as structural modification, dosage form optimization and combination medication to improve the yield and anti-tumor activity of diosgenin. Via the summary of this paper, it is expected to provide theoretical basis for the rational exploitation and utilization of diosgenin.

Efficacy of TCM therapy of tonifying lung-kidney's Qi-deficiency in a case of idiopathic pulmonary fibrosis: A case report.

RATIONALE: Idiopathic pulmonary fibrosis (IPF) is a special form of spontaneous, chronic, progressive interstitial fibrotic pneumonia of unknown cause, and treatments for IPF have shown a poor prognosis. This study reports a new treatment, traditional Chinese medicine (TCM) therapy, for tonifying Qi-deficiency of lung-kidney in a 64-year-old patient with IPF. PATIENT CONCERNS: A 64-year-old man, who complained of cough and asthma, was diagnosed as IPF with mild impairment in lung function by thoracic high-resolution computed tomography and pulmonary function test. He received an 18-month N-acetylcysteine monotherapy but had no improvement in lung function. DIAGNOSES: IPF with mild impairment in lung function was diagnosed. INTERVENTIONS: The Chinese herbal medicine composition was decocted in 300 ml water for oral administration with 150 ml decoction twice daily in June 2017. OUTCOMES: The pulmonary function test showed that diffusing capacity for carbon monoxide had increased to 81% of predicted back to normal after 2-month TCM monotherapy. And diffusing capacity for carbon monoxide had increased to 89% of predicted, and forced expiratory volume in 1 s/forced vital capacity ratio increased to 92% at 14-month follow-up. No adverse events occurred during the 14 months of therapy and observation. LESSONS: The treatment by TCM therapy of tonifying lung-kidney's Qi-deficiency for IPF can improve the pulmonary function and reverse disease progression; it may be considered as a complementary treatment for IPF with mild-to-moderate impairment. However, the insights provided in this case report require further exploration and verification.

Large-scale converting waste coffee grounds into functional carbon materials as high-efficient adsorbent for organic dyes.

Functional carbon materials have been fabricated through simple and effective catalytic carbonization with waste coffee grounds (CGs) as carbon precursor and FeCl3 as catalyst. The effect of FeCl3 loading and carbonization temperature on carbon yield was investigated. The morphology and structure of as-synthesized carbons was characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD), Raman spectroscopy, X-ray photoelectron spectroscopy (XPS) and nitrogen isothermal adsorption/desorption measurement, respectively. Furthermore, the carbon materials showed high efficiency for the removal of methylene blue (MB, 653.6 mg g-1), methyl orange (MO, 465.8 mg g-1) and rhodamine B (RB, 366.1 mg g-1). More importantly, the carbon was magnetic, so it can be easily separated by a magnet and reused multiple times. This work not only exploited a low-cost and large-scale preparation method to synthesize functional carbon materials from bioresources, but also provided an eco-friendly and effective adsorbent in water purification applications.

Efficacy of Chinese herbal medicine in a case of geriatric urinary tract infections with pain of episiotomy scar inflammation.

RATIONALE: Urinary tract infections (UTIs) are common infectious diseases in women. The management of patients with UTI after menopause is commonly combined with antibiotics and external application of estrogen, which could also cause drug resistance and result in poor curative effect. This study reports a case of UTI with pain of episiotomy scar inflammation for 10 years, which was successfully cured under traditional Chinese medicine (TCM) and showed no recurrence for 5 years. PATIENT CONCERNS: A female patient, aged 71 years, experienced UTIs with pain of episiotomy scar inflammation for 10 years. Under antibiotics and external application of estrogen therapy, the patient still had no significant curative effect. Therefore, he was admitted to treatment with TCM for complementary therapy. DIAGNOSIS: UTIs with pain of episiotomy scar inflammation. INTERVENTIONS: This patient was treated with Chinese herbal medicine (CHM) treatment 2 times a day for 1 year. After 1 month of CHM treatment, the patient could tolerate pain of episiotomy scar inflammation. OUTCOMES: After 2 months of CHM treatment, the follow-up urinalysis leukocyte, red blood cell, and pH showed great improvements in examination. Late follow-up was continued to November 2017, and the patient recovered stable condition without recurrence. LESSONS: In this case, successful treatment by only applying the prescription of CHM is achieved in 1 elderly woman with UTI and pain of episiotomy scar inflammation in 1 year. It is suggested that the CHM formula has a potential effect on UTI and pain from episiotomy scar inflammation when usage of antibiotics and hormones meets with poor response.

[Species diversity and temporal niche of entomopathogenic fungi in the extensively managed tea plantation soil].

The species diversity and temporal niche of entomopathogenic fungi community in the rhizosphere soil collected from the extensively managed Huangshan fuzz tip tea plantation were investigated. A total of 140 soil samples were collected at the location of Tangkou Town, Huangshan of Anhui Province during August, 2012 to June, 2013, and totally 1041 fungal isolates were obtained on selective medium with soil dilution plating. The results showed that the entomopathogenic fungi community in the tea plantation soil was diverse with 13 species in 6 genera. Purpureocillium lilacinum (309 strains), Beauveria bassiana (255 strains), and Metarhizium anisopliae (101 strains) were the dominant species accounting for 29.7%, 24.5% and 9.7% of the relative frequency, respectively. P. lilacinum had the widest temporal niche breadth among these dominant entomopathogenic fungi from the tea plantation soil, while B. bassiana had the narrowest. Among the entomopathogenic fungi, B. bassiana and B. brongniartii had the biggest temporal niche overlap of 1.965, while Isaria javanicus and B. bassiana had the smallest of 0.374.

[Traditional Chinese medicine constitution types in 127 elderly patients with insomnia: an investigation in communities of Yangpu District, Shanghai].

OBJECTIVE: To analyze the distribution of traditional Chinese medicine constitution types in elderly patients with insomnia. METHODS: The epidemiological data were collected from communities in the Yangpu District, Shanghai via a cross-sectional field survey. The elderly participants were enrolled by using the Pittsburgh Sleep Quality Index (PSQI) scale and the TCM Constitution Questionnaire. RESULTS: (1)The distribution of imbalanced constitutions between the elderly with insomnia and normal subjects showed statistical difference (P<0.01) and the elderly with insomnia tend to be of imbalanced constitutions. Among these unbalanced constitutions, deficient constitutions were more frequent than others in the elderly with insomnia, and yang-deficiency and qi-deficiency occurred mostly in unbalanced and simple constitutions. (2) Blood-stasis and qi-stagnation constitutions were more frequent in females than in males among the elderly with insomnia. Frequency of deficiency constitutions in the elderly increased as the age increases. (3) The frequency of composite constitutions was higher than that of simple constitutions in elderly patients with insomnia (74.8%), among which qi-deficiency was more likely to be composite with other constitutions. CONCLUSION: Identification and classification of traditional Chinese medicine constitution types will provide further information for devising projects with systematic intervention for insomnia management.
