Psyllium husk powder increases defecation frequency and faecal score, bulk and moisture in healthy cats.

OBJECTIVES: Constipation is the infrequent or difficult emission of hard, dry faeces and is a common digestive condition in cats. Psyllium is a low-fermentable fibre, with soluble and insoluble components and water-holding properties. It forms a mucilaginous gel with water and is used for the symptomatic treatment of constipation in various species. This study evaluated the effect of dietary psyllium on faecal characteristics in cats. METHODS: Healthy neutered adult cats (six female and three male, aged 3.3-4.4 years) were consecutively fed a dry extruded diet containing either 6% psyllium (test) or 6% cellulose (control) for 10 days each. During the last 3 days (the collection days) of both feeding periods, bowel movements and faecal scores were recorded, and faeces were collected to measure wet weight and moisture. The statistical analysis used linear mixed models with diet, day and their interaction as fixed effects and animal as a random term. RESULTS: The test diet was associated with significantly more bowel movements per day over 3 days (P = 0.0052) and on collection day 2 (P = 0.0229) than the control diet. The mean faecal score was higher (softer faeces) over all three collection days (P <0.0001) and on collection days 1, 2 and 3 (P = 0.0011, P = 0.0349, P = 0.0003, respectively) for the test diet vs the control diet; the total faecal wet weight (P = 0.0003) and faecal moisture (%) were also higher (P = 0.0426) for the test diet. Faeces associated with the test diet often had a dry shell and soft interior, which increased the faecal score. CONCLUSIONS AND RELEVANCE: Psyllium promoted more bowel movements and higher faecal moisture and faecal score in healthy cats, consistent with a previous uncontrolled clinical trial in constipated cats. Together, the studies support the use of dietary psyllium for managing cats with constipation.

Efficacy and safety of Xiaofeng powder in the treatment of chronic urticaria: A systematic review and meta-analysis.

BACKGROUND: Chronic urticaria is a group of skin diseases characterized by pruritus and/or vascular oedema and belongs to the category of "addictive rash" in Traditional Chinese Medicine, and its aetiology is closely related to wind evil. Antihistamines are often used in treatment. Although they have certain effects, they also easily cause disease recurrence. Xiaofeng powder treats this disease has a significant effect in improving the disease state and reducing the recurrence rate. However, there is a lack of evidencebased research. This study to systematically evaluate the clinical efficacy of modified Xiaofeng powder in the treatment of chronic urticaria (CU). METHODS: Computer searches of Chinese databases such as China National Knowledge Infrastructure, China Scientific Journal Database, China Biomedical Literature Database, and WanFang Date and foreign databases such as PubMed and the Web of Science were performed. We retrieved published clinical randomized controlled trials of Xiaofeng powder in the treatment of CU from the establishment of the databases to November 2023. The data were extracted from clinical trials that met the inclusion criteria of this study, and the quality was evaluated through the Cochrane Handbook of Systematic Reviews 5.1.0. Finally, a meta-analysis was performed using RevMan 5.3 statistical software. RESULTS: A total of 11 randomized controlled trials involving 1076 patients were included. The cure rate odds ratio (OR) and 95% confidence interval (CI; shown in brackets) were 2.11 [1.45, 3.07]; the total effective rate OR and CI were 2.42 [1.60, 3.68]; the recurrence rate OR and CI were 0.22 [0.15, 0.34]; the adverse reaction rate OR and CI were 0.23 [0.12, 0.45]; and the mean weighted mean difference (MD) and 95% CI (shown in brackets) of itching degree, wind mass size, wind mass number and wind mass duration in symptom and sign integrals were -0.70 [-0.73, 0.67], -0.64 [-0.96, 0.31], , -0.72 [-1.23, 0.22], and -0.68 [-1.13, 0.23], , respectively. CONCLUSION: The clinical efficacy of modified Xiaofeng powder in the treatment of CU is better than that of antihistamine drugs, with lower adverse reaction and recurrence rates and higher safety. However, the quality of clinical research included is relatively low, and findings need to be confirmed by high-quality research.

Synergy of de-walled Ganoderma Lucidum spore powder (GLSP) on targeted therapy in advanced non-squamous non-small cell lung cancer with epidermal growth factor receptor (EGFR) mutant: protocol for a randomized, double-blind, placebo-controlled study.

BACKGROUND: Osimertinib is regarded as a promising third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) for advanced non-squamous non-small cell lung cancer (NSCLC) patients who developed T790M. However the adverse effects, primarily fatigue, remain an overwhelming deficiency of Osimertinib, hindering it from achieving adequate clinical efficacy for such NSCLC. Ganoderma lucidum has been used for thousands of years in China to combat fatigue, while Ganoderma Lucidum spores powder (GLSP) is the main active ingredient. The aim of this study is to investigate whether GLSP is sufficiently effective and safe in improving fatigue and synergizing with Osimertinib in non-squamous NSCLC patients with EGFR mutant. METHOD/DESIGN: A total of 140 participants will be randomly assigned to receive either de-walled GSLP or placebo for a duration of 56 days. The primary outcome measure is the fatigue score associated with EGFR-TKI adverse reactions at week 8, evaluated by the Chinese version of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire for Cancer Patients (QLQ-C30). Secondary outcomes include evaluation of treatment effectiveness, assessment of quality of life (QoL), and exploration of immune indicators and gut microbiota relationships. Following enrollment, visits are scheduled biweekly until week 12. TRIAL REGISTRATION: China Clinical Trial Registry ChiCTR2300072786. Registrated on June 25, 2023.

OBJECTIVES: To observe the clinical efficacy of heat-sensitive moxibustion combined with Xiangwu powder in treating erectile dysfunction with kidney deficiency and blood stasis. METHODS: A total of 80 patients with erectile dysfunction of kidney deficiency and blood stasis were randomly divided into a comprehensive group (40 cases, 1 case dropped out) and a Chinese herb group (40 cases, 2 cases dropped out). In the Chinese herb group, Xiangwu powder was applied orally, one dose per day. On the basis of the Chinese herb group, heat-sensitive moxibustion was applied after detecting the heat-sensitive points in the areas of Guanyuan (CV 4), Zhongji (CV 3), Qihai (CV 6) and bilateral Xuehai (SP 10), Sanyinjiao (SP 6) in the comprehensive group, once a day, 5 times a week. Both groups were treated for 4 weeks. The international index of erectile function-5 (IIEF-5) score, erectile hardness score (EHS), nocturnal penile tumescence and rigidity (NPTR) indexes (nocturnal penile erection frequency, total duration of penile erection, duration of penile head hardness ≥60%, duration of penile root hardness ≥60%, percentage change in penile head circumference, percentage change in penile root circumference), TCM syndrome score, and penile vascular function indexes (peak systolic velocity [PSV], end diastolic velocity [EDV], and resistance index [RI] of penile cavernosal artery) were compared in the patients of the two groups before and after treatment, and the clinical efficacy was evaluated. RESULTS: After treatment, the IIEF-5 scores, EHS, PSV, RI, and NPTR indexes were increased compared with those before treatment (P<0.01), while the TCM syndrome scores and EDV were decreased compared with those before treatment (P<0.01) in the two groups.The IIEF-5 score, EHS, PSV, RI, and NPTR indexes in the comprehensive group were ascended compared with those in the Chinese herb group (P<0.01), while the TCM syndrome score and EDV in the comprehensive group were lower than those in the traditional Chinese herb group (P<0.01). The total effective rate of the comprehensive group was 94.9% (37/39), which was higher than 78.9% (30/38, P<0.05) of the Chinese herb group. CONCLUSIONS: The combination of heat-sensitive moxibustion and Xiangwu powder can effectively treat erectile dysfunction of kidney deficiency and blood stasis, improve patients' erectile function, enhance their erection hardness, and improve their penile vascular function and clinical symptoms.

Zhisou powder suppresses airway inflammation in LPS and CS-induced post-infectious cough model mice via TRPA1/TRPV1 channels.

ETHNOPHARMACOLOGICAL RELEVANCE: Zhisou Powder (ZSP), a traditional Chinese medicine (TCM) prescription, has been widely used in the clinic for the treatment of post-infectious cough (PIC). However, the exact mechanism is not clear. AIM OF THE STUDY: The aim of this study was to investigate the ameliorative effect of ZSP on PIC in mice. The possible mechanisms of action were screened based on network pharmacology, and the potential mechanisms were explored through molecular docking and in vivo experimental validation. MATERIALS AND METHODS: Lipopolysaccharide (LPS) (80µg/50 µL) was used to induce PIC in mice, followed by daily exposure to cigarette smoke (CS) for 30 min for 30 d to establish PIC model. The effects of ZSP on PIC mice were observed by detecting the number of coughs and cough latency, peripheral blood and bronchoalveolar lavage fluid (BALF) inflammatory cell counts, enzyme-linked immunosorbent assay (ELISA), and histological analysis. The core targets and key pathways of ZSP on PIC were analyzed using network pharmacology, and TRPA1 and TRPV1 were validated using RT-qPCR and western blotting assays. RESULTS: ZSP effectively reduced the number of coughs and prolonged the cough latency in PIC mice. Airway inflammation was alleviated by reducing the expression levels of the inflammatory mediators TNF-α and IL-1ß. ZSP modulated the expression of Substance P, Calcitonin gene-related peptide (CGRP), and nerve growth factor (NGF) in BALF. Based on the results of network pharmacology, the mechanism of action of ZSP may exert anti-neurogenic airway-derived inflammation by regulating the expression of TRPA1 and TRPV1 through the natural active ingredients α-spinastero, shionone and didehydrotuberostemonine. CONCLUSION: ZSP exerts anti-airway inflammatory effects through inhibition of TRPA1/TRPV1 channels regulating neuropeptides to alleviate cough hypersensitivity and has a favorable therapeutic effect on PIC model mice. It provides theoretical evidence for the clinical application of ZSP.

Classical prescription Floris Sophorae Powder treat colorectal cancer by regulating KRAS/MEK-ERK signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Colorectal cancer (CRC) belongs to the category of intestinal wind, anal ulcer, abdominal mass and other diseases in traditional Chinese medicine (TCM). Floris Sophorae Powder (F.S), is a classical prescription is recorded in Puji Benshi Fang for the treatment of intestinal carbuncle. It has been incorporated into the prescriptions for the treatment of intestinal diseases and achieved remarkable results in modern medicine. However, the mechanism of F.S in the treatment of colorectal cancer remains unclear and requires further study. AIM OF THE STUDY: To investigate F.S in treating CRC and clarify the underlying mechanism. MATERIALS AND METHODS: This study was based on Dextran Sulfate Sodium Salt (DSS) combined with Azoxymethane (AOM) induced CRC mouse model to clarify the pharmacological effects of F.S. The serum metabolomics was used to study the mechanism of action, and the chemical composition of F.S was found by UPLC-Q-TOF-MS. The rationality of serm metabolomics results was verified through the clinical target database of network pharmacology, and the upstream and downstream targets of related pathways were found. The mechanism pathway was verified by Western blot to clarify its mechanism of action. RESULTS: In vivo pharmacological experiments showed that F.S inhibited tumor growth and improved hematochezia. The vital signs of mice in the high-dose F.S group approached to those in the control group. A total of 43 differential metabolites were found to be significantly changed by serum metabolomics. F.S could modulate and recover most of the differential metabolites, which proved to be closely related to the KRAS/MEK-ERK signaling pathway. A total of 46 compounds in F.S were identified, and the rationality of serm metabolic pathway was verified by network pharmacology. Western blot results also verified that the expression of KRAS, E2F1, p-MEK and p-ERK were significantly decreased after F.S treatment. CONCLUSION: Classical prescription Floris Sophorae Powder treat colorectal cancer by regulating KRAS/MEK-ERK signaling pathway.

Modified Danzhi Xiaoyao Powder (MDXP) improves the corneal damage in dry eye disease (DED) mice through phagocytosis.

ETHNOPHARMACOLOGICAL RELEVANCE: Modified Danzhi Xiaoyao Powder (MDXP) is a traditional Chinese medicine formula remedy for treating Dry Eye Disease (DED). It showed the function of dispersing stagnated liver Qi for relieving Qi stagnation and clearing heat, which can be effective in treating conditions such as Dry Eye Disease (DED) and irregular menstruation due to liver depression and fire transformation. AIM OF THE STUDY: This study investigated the mechanism of the effect of MDXP in mice with DED. MATERIALS AND METHODS: A DED model was induced in mice using chronic painful stimulation (tail clamping) in combination with Benzalkonium Chloride Solution drops administered in a dry box for 28 days. After modeling, the MDXP groups were given Chinese medicine with different dosages by gavage for 14 days. The following parameters were recorded in each group: body mass, anal temperature, tear secretion, tear film rupture time, and corneal fluorescein staining. Behavioral changes were evaluated by elevating cross-maze and open-field experiments. The levels of inflammatory factors serum tumor necrosis factor-α (TNF-α), interleukin 1ß (IL-1ß), fcγR-mediated phagocytosis pathway cell division control protein 42 homolog (CDC42), actin-related protein 2/3 complex subunit 2 (ARPC2), and actin-related protein 3 (ACTR3) were measured by using Enzyme-linked immunoassay (ELISA), immunohistochemical staining, and real-time fluorescent qualitative polymerase chain reaction (RT-qPCR). RESULTS: MDXP increased body mass and lowered body temperature, prolonged tear film break-up time, promoted tear secretion, repaired corneal damage, decreased horizontal and vertical scores, elevated percentage of open arm times and boom opening time percentage, and reduced the expression levels of inflammatory factors of TNF-α, IL-1ß and pathway-related proteins CDC42, ARPC2, and ACTR3 in mice. MDXP also reduced the expression levels of inflammatory factors of TNF-α and IL-1ß in human corneal endothelial cells (HCECs), mouse mononuclear macrophage cells (RAW264.7), and human myeloid leukemia mononuclear cells (THP-1). CONCLUSIONS: MDXP can relieve tension and anxiety, inhibit apoptosis, reduce phagocytosis, reduce the expression of pro-inflammatory factors, repair corneal damage, and improve the symptoms in DED mice. The mechanism of action may be through the fcγR-mediated phagocytosis pathway.

Effect of Medicago sativa seed powder (Plus vitamin E vs. vitamin E alone) on semen analysis in men with idiopathic infertility: A double blind randomized clinical trial.

ETHNOPHARMACOLOGICAL RELEVANCE: Different parts of the alfalfa plant (Medicago sativa L.), especially its seeds, have been introduced as a semen quality enhancer in the folk medicine of different regions of Iran as well as in the traditional Persian medicine (PM) books. The seeds of this plant are also used in many combined medicines to treat male infertility in PM. AIM OF THE STUDY: This study was designed to investigate the effect of M. sativa seed powder plus vitamin E vs. vitamin E alone on semen analysis of men with idiopathic infertility. MATERIALS AND METHODS: In this randomized clinical trial, 60 participants were randomly divided into two groups and then received M. sativa seed powder (6 g daily) or placebo for three months, as add-on to vitamin E (100 U). Results of semen analysis (sperm total count, motility, and morphology as well as semen volume) of these two groups and their changes were compared before and after treatment as the primary outcome. The number of pregnancies after one month and probable side effects were also assessed. RESULTS: After 12 weeks, sperm total count changed from 36.2 ± 21.8 × 106/ml to 48.5 ± 19.1 × 106/ml in M. sativa and from 39.5 ± 23.5 × 106/ml to 41.2 ± 20.9 × 106/ml in placebo, percentage of normal morphology changed from 1.8 ± 0.8% to 2.6 ± 1.2 % in M. sativa and from 2.0 ± 0.9% to 2.6 ± 1.2% in placebo and percentage of motile sperm changed from 36.5 ± 11.8 % to 39.7 ± 12.0% in M. sativa and from 39.3 ± 10.1 % to 38.1 ± 12.1% in placebo. The improvements in M. sativa group are significantly better than placebo group (P = 0.00, 0.01 and 0.04, respectively). However, semen volume decreased in both groups, but its changes were not significant. The number of pregnancies was four in the intervention and zero in placebo group. One case with abdominal bloating and one with respiratory allergy withdrew from the intervention group. No other adverse effect was reported. CONCLUSIONS: In this study, significant improvement was detected in sperm parameters (except semen volume) of men with idiopathic infertility in M. sativa plus vitamin E group in compare to vitamin E alone after 12 weeks. These findings suggest that the M. sativa, as a complementary therapy, may have a beneficial effect on semen quality. More clinical trials with larger sample size are needed.

Bear bile powder alleviates Parkinson's disease-like behavior in mice by inhibiting astrocyte-mediated neuroinflammation.

Parkinson's disease (PD) is a common neurodegenerative disease in middle-aged and elderly people. In particular, increasing evidence has showed that astrocyte-mediated neuroinflammation is involved in the pathogenesis of PD. As a precious traditional Chinese medicine, bear bile powder (BBP) has a long history of use in clinical practice. It has numerous activities, such as clearing heat, calming the liver wind and anti-inflammation, and also exhibits good therapeutic effect on convulsive epilepsy. However, whether BBP can prevent the development of PD has not been elucidated. Hence, this study was designed to explore the effect and mechanism of BBP on suppressing astrocyte-mediated neuroinflammation in a mouse model of PD. PD-like behavior was induced in the mice by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) (30 mg·kg-1) for five days, followed by BBP (50, 100, and 200 mg·kg-1) treatment daily for ten days. LPS stimulated rat C6 astrocytic cells were used as a cell model of neuroinflammation. THe results indicated that BBP treatment significantly ameliorated dyskinesia, increased the levels of tyrosine hydroxylase (TH) and inhibited astrocyte hyperactivation in the substantia nigra (SN) of PD mice. Furthermore, BBP decreased the protein levels of glial fibrillary acidic protein (GFAP), cyclooxygenase 2 (COX2) and inducible nitric oxide synthase (iNOS), and up-regulated the protein levels of takeda G protein-coupled receptor 5 (TGR5) in the SN. Moreover, BBP significantly activated TGR5 in a dose-dependent manner, and decreased the protein levels of GFAP, iNOS and COX2, as well as the mRNA levels of GFAP, iNOS, COX2, interleukin (IL) -1ß, IL-6 and tumor necrosis factor-α (TNF-α) in LPS-stimulated C6 cells. Notably, BBP suppressed the phosphorylation of protein kinase B (AKT), inhibitor of NF-κB (IκBα) and nuclear factor-κB (NF-κB) proteins in vivo and in vitro. We also observed that TGR5 inhibitor triamterene attenuated the anti-neuroinflammatory effect of BBP on LPS-stimulated C6 cells. Taken together, BBP alleviates the progression of PD mice by suppressing astrocyte-mediated inflammation via TGR5.

Cod (Gadus) skin collagen peptide powder reduces inflammation, restores mucosal barrier function, and inhibits fibrosis in dextran sodium sulfate-induced colitis in mice.

ETHNOPHARMACOLOGICAL RELEVANCE: Ulcerative colitis (UC) is a chronic inflammatory bowel disease of unknown etiology. Cod (Gadus), a kind of herb from the Chinese herb. Traditionally, it has used to treat trauma, reduce swelling and relieve pain in order to exert its anti-inflammatory activity. Recent reports based on its hydrolyzed or enzymatic extracts have shown its anti-inflammatory, mucosal barrier protecting properties. However, its mechanism of improvement in ulcerative colitis is not clear. AIM OF THE STUDY: This study aimed to explore the preventive and protective effect of cod skin collagen peptide powder (CP) on mice with UC and to explore the underlying mechanism. MATERIALS AND METHODS: Mice with dextran sodium sulfate (DSS)-induced UC were treated with CP by gavage, and the anti-inflammatory effects of CP were assessed using general physical, pro-inflammatory cytokine, histopathological, immunohistochemical, macrophage flow cytometry, and inflammatory signaling pathway assays. RESULTS: CP ameliorates inflammation by upregulating mitogen-activated protein kinase phosphatase-1 (MKP-1) and thereby decreasing the phosphorylation levels of P38 and JNK. It also polarizes macrophages in the colon towards the M2 phenotype, which helps to reduce tissue damage and promotes colon repair. At the same time, CP also inhibits the development of fibrosis, one of the complications of UC, by upregulating ZO-1, Occludin, and downregulating α-SMA, Vimentin, Snail, and Slug. CONCLUSION: In this study, we found CP reduced inflammation in mice with UC by inducing MKP-1 expression, which caused dephosphorylation of mitogen-activated protein kinase (MAPK). CP also restored mucosal barrier function and inhibited the development of fibrosis complicating UC in these mice. Taken together, these results suggested that CP improved the pathological manifestations of UC in mice, suggesting that it can play a biological role as a nutritional supplement for preventing and treating UC.

The Efficacy and Safety of Bionic Tiger Bone Powder for the Treatment of Knee Osteoarthritis in Early Stage: A Randomized, Double-Blind, Placebo-Controlled, Multicenter Clinical Trial.

Objective: This study evaluated the efficacy and safety of bionic tiger bone powder (Jintiange) in comparison to placebo in treating knee osteoarthritis osteoporosis. Methods: A total of 248 patients were randomly allocated to a Jintiange group or a placebo group, undergoing 48 weeks of double-blind treatment. The Lequesne index, clinical symptoms, safety index (adverse events), and Patient's Global Impression of Change score were recorded at pre-determined time intervals. All P values ≤ .05 were deemed statistically significant. Results: Both groups showed a decreasing trend in the Lequesne index, with the Jintiange group's reduction significantly larger from the 12th week (P ≤ .01). Similarly, the effective rate of Lequesne score in the Jintiange group was significantly higher (P < .001). After 48 weeks, clinical symptom score differences between the Jintiange group (2.46 ± 1.74) and the placebo group (1.51 ± 1.73) were statistically significant (P < .05), as were differences in the Patient's Global Impression of Change score (P < .05). Adverse drug reactions were minimal with no significant difference between the groups (P > .05). Conclusion: Jintiange demonstrated superior efficacy over placebo in treating knee osteoporosis, with comparable safety profiles. Findings warrant further comprehensive real-world studies.

Tou Nong powder obstructs ulcerative colitis through the regulation of NF-κB/NLRP3/Caspase-1/GSDMD inflammasome pyroptotic pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Tou Nong Powder (TNP), a classical Chinese medicinal formula originated from the Chinese Ming Dynasty, has been applied to treat skin ulcers in patients with deficient constitutions. According to theory of traditional Chinese medicine, colonic ulcers share similar pathological conditions with skin ulcers, and consequently, TNP has been applied to ulcerative colitis (UC) safely and effectively. AIM OF STUDY: To investigate whether TNP obstructs 2,4,6-trinitrobenzene sulfonic acid (TNBS) induced enteric inflammation through regulation of NLRP3 inflammasome and attenuating enteric pyroptosis. MATERIALS AND METHODS: Network pharmacology and UPLC-Q-TOF/MS were operated to identify compounds and pharmacological potential targets. The therapeutic effects of TNP were assessed on TNBS induced colitis via general symptoms (disease activity index, colonic weight and length) and histopathological observation. The NF-κB/NLRP3/Caspase-1/GSDMD signaling pathway regulation was investigated by Western blot and real time reverse transcription polymerase chain reaction (RT-qPCR). RESULTS: TNP ameliorates the disease activity index, reverses the increase of colonic weight increase, alleviates colonic shortening and colonic histopathological injury. A decrease in tumor necrosis factor α (TNF-α), diamine oxidase (DAO), intercellular adhesion molecule-1 (ICAM-1), and endo-toxin (ET) were investigated in peripheral circulation. Moreover, TNP significantly obstructed the NF-κB/NLRP3/Caspase-1/GSDMD signaling pathway. CONCLUSION: TNP displays a promising therapeutic effect on UC via suppressing NF-κB/NLRP3/Caspase-1/GSDMD signaling pathway and reducing the expression of IL-1ß and IL-18.

Effect of green-lipped mussel (Perna canaliculus) supplementation on faecal microbiota, body composition and iron status markers in overweight and obese postmenopausal women: a randomised, double-blind, placebo-controlled trial.

The present study aimed to determine the effect of whole meat GSM powder on gut microbiota abundance, body composition and iron status markers in healthy overweight or obese postmenopausal women. This was a 3-months trial involving forty-nine healthy postmenopausal women with body mass index (BMI) between 25 and 35 kg/m2 who were randomly assigned to receive 3 g/d of either GSM powder (n 25) or placebo (n 24). The gut microbe abundance, serum iron status markers and body composition were measured at the baseline and the end of the study. The between-group comparison at the baseline showed a lower abundance of Bacteroides and Clostridium XIVa in the GSM group compared with the placebo (P = 0⋅04). At the baseline, the body fat (BF)% and gynoid fat% were higher in the GSM group compared with the placebo (P < 0⋅05). No significant changes were found in any of the outcome measures, except for ferritin levels that showed a significant reduction over time (time effect P = 0⋅01). Some trend was observed in bacteria including Bacteroides and Bifidobacterium which tended to increase in the GSM group while their abundance decreased or remained at their baseline level in the control group. Supplementation with GSM powder did not result in any significant changes in gut microbe abundance, body composition and iron markers compared with placebo. However, some commensal bacteria such as Bacteroides and Bifidobacteria tended to increase following supplementation with GSM powder. Overall, these findings can expand the knowledge surrounding the effects of whole GSM powder on these outcome measures in healthy postmenopausal women.

Comparing Arsenic-Containing Qinghuang Powder and Low-Intensity Chemotherapy in Elderly Patients with Acute Myeloid Leukemia.

OBJECTIVE: To compare the clinical effect of arsenic-containing Qinghuang Powder (QHP) and low-intensity chemotherapy (LIC) in treatment of elderly acute myeloid leukemia (eAML) patients. METHODS: Clinical data of 80 eAML patients treated at Xiyuan Hospital of China Academy of Chinese Medical Sciences from January 2015 to December 2020 were retrospectively analyzed. The treatment scheme was designed by real world study according to patients' preference, and patients were divided into a QHP group (35 cases) and a LIC group (45 cases). The median overall survival (mOS), 1-, 2-, and 3-year OS rates, and incidence of adverse events were compared between the two groups. RESULTS: The mOS of 80 patients was 11 months, and the 1-, 2-, and 3-year OS rates were 45.51%, 17.96%, and 11.05%, respectively. The QHP and LIC groups demonstrated no significant difference in mOS (12 months vs. 10 months), 1- (48.57% vs. 39.65%), 2- (11.43% vs. 20.04%), and 3-year OS rates (5.71% vs. 13.27%, all P>0.05). Moreover, the related factors of mOS demonstrated no significant difference in patients with age>75 years (11 months vs. 8 months), secondary AML (11 months vs. 8 months), poor genetic prognosis (9 months vs. 7 months), Eastern Cooperative Oncology Group performance status score ⩾ 3 (10 months vs. 7 months) and hematopoietic stem cell transplant comorbidity index ⩾ 4 (11 months vs. 7 months) between the QHP and LIC groups (all P>0.05). However, the incidence of myelosuppression was significantly lower in the QHP group than that in the LIC group (28.57% vs. 73.33%, P<0.01). CONCLUSIONS: QHP and LIC had similar survival rates in eAML patients, but QHP had a lower myelosuppression incidence. Hence, QHP can be an alternative for eAML patients who do not tolerate LIC.

Sativa with quadruple therapy or 2 g/day placebo plus quadruple therapy for 8 weeks. The serum level of ghrelin was assessed before and after the intervention. Appetite was evaluated at the onset and at the end of the intervention. RESULTS: At the end of the study, the appetite of the treatment group improved significantly compared with the placebo group (P = 0.02). Statistically, the difference in serum ghrelin levels between the study's groups was insignificant (P > 0.05). CONCLUSION: Supplementation with N. Sativa powder may be a beneficial adjunctive therapy in H. pylori-infected patients. TRIAL REGISTRATION: This study was registered in the Iranian Registry of Clinical Trials (IRCT20170916036204N7) on 08/08/2018.

Effectiveness and safety analysis of Danggui Shaoyao Powder for the treatment of non-alcoholic fatty liver disease: study protocol for a randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND: The incidence of non-alcoholic fatty liver disease (NAFLD) has been on the rise in recent years, and there are no effective drugs to treat NAFLD; therefore, effective prevention and treatment of NAFLD have become a new challenge. Danggui Shaoyao Powder (DGSY) is a classic prescription commonly used in clinical practice and has been shown to reduce hepatic steatosis in patients with NAFLD. In addition, previous studies have shown that DGSY can alleviate hepatic steatosis and inflammation in NAFLD mice. Although clinical practice and basic studies have shown that DGSY is effective in NAFLD, high levels of clinical evidence are lacking. Therefore, a standardized RCT study protocol is required to evaluate its clinical efficacy and safety. METHODS AND ANALYSIS: This study will be a randomized, double-blind, placebo-controlled, and single-center trial. According to the random number table, NAFLD participants will be randomly divided into the DGSY or placebo group for 24 weeks. The follow-up period will be 6 weeks after drug withdrawal. The primary outcome is the relative change in MRI-proton density fat fraction (MRI-PDFF) from baseline to 24 weeks. Absolute changes in serum alanine aminotransferase (ALT), liver stiffness measurement (LSM), body mass index (BMI), blood lipid, blood glucose, and insulin resistance index will be selected as secondary outcomes to comprehensively evaluate the clinical efficacy of DGSY in the treatment of NAFLD. The safety of DGSY will be evaluated by renal function, routine blood and urine tests, and electrocardiogram. DISCUSSION: This study will provide evidence-based medical corroboration for the clinical application of DGSY and promote the development and application of this classic prescription.

OBJECTIVES: Unani physicians have suggested a wide range of anti-dermatophytic remedies, although the scientific evidence is scarce. Thus, the efficacy and safety of Terminalia chebula Retz. fruit powder mixed with vinegar was compared with terbinafine hydrochloride 1% cream in the treatment of tinea corporis in order to establish the non-inferiority of test drugs. METHODS: The primary outcome measures were change in the presence or absence of hyphae on KOH mount test, change in pruritus severity assessed on 100 mm VAS and change in physician's global assessment. Secondary outcome measure was change in the dermatology life quality index (DLQI). Hemograms, serum creatinine, serum bilirubin, and random blood sugar levels were measured at the baseline and after treatment to ensure the safety of the interventions. RESULTS: A per-protocol analysis was done on 40 participants (21 in the test group and 19 in the control group). The observed differences in the primary and secondary outcomes between the test and control groups were greater than the non-inferiority margin, signifying that the test drugs were not inferior. CONCLUSIONS: It may be inferred that the trial drug Terminalia chebula Retz. fruit powder mixed with vinegar is not inferior to terbinafine hydrochloride cream in the treatment of tinea corporis.

Hypoglycemic Effect of Trichosanthes pericarpium to Type 2 Model Diabetic Mice via Intestinal Bacteria Transplantation.

BACKGROUND: The treatment of diabetes with plant ingredients such as in Traditional Chinese Medicine (TCM) is an alternative to classical chemotherapy. OBJECTIVE: This study aims to explore the hypoglycemic effect of Trichosanthes pericarpium powder (TP) and intestinal bacteria transplantation in type 2 diabetic mice. The relationship between intestinal bacteria transplantation and improvement in insulin resistance was also investigated. METHODS: The polyphenols and terpenoids in the TP were identified by LC-MS/MS. Streptozotocin was used to induce a mouse model of type 2 diabetes. Diabetic mice were treated with different doses of TP and the intestinal bacteria obtained from the high-dose TP group for four weeks. RESULTS: As a result, FBG levels were found to be significantly reduced in diabetic mice, weight gain and organ enlargement were alleviated, and insulin resistance was significantly improved. TP administration also improved the disorder in intestinal bacteria in diabetic mice. Besides, TP can increase the liver AMPK, SIRT1, GLUT1, and GLUT4 gene expression, while down-regulated PEPCK and G6Pase gene expression suggest a potential mechanism for hypoglycemia in diabetic mice. CONCLUSION: Oral administration of Trichosanthes pericarpium powder in the treatment of diabetes may be achieved by restoring hepatic function, improving insulin resistance, and the dynamic balance of intestinal bacteria.

Compound shougong powder inhibits the malignant phenotype of hepatocellular carcinoma cells by targeting the DNA damage repair pathway.

OBJECTIVES: Compound Shougong Powder (SGS), a traditional Chinese medicine formulation, has been used to treat cancer for many years with remarkable efficacy. However, the mechanisms underlying the therapeutic effect of SGS in Hepatocellular carcinoma (HCC) are not completely clear. METHODS: The survival and metastasis of HCC cells were examined by CCK-8 assay, EdU assay, Wound-healing and Transwell assay. The anti-tumour effect of SGS was studied using hoechst 33258 staining and flow cytometry. RNA sequencing was applied to detect the underlying mechanism. Comet DNA, qRT-PCR and WB experiments were performed for validation. In addition, HCC nude mouse model was constructed to detect SGS effect in vivo. KEY FINDINGS: SGS inhibited the proliferation, migration and invasion of HCC cells and induced apoptosis in vitro. In addition, SGS also suppressed tumour growth in a nude mouse model of HCC in a dose-dependent manner. RNA sequencing of the suitably treated HCC cells revealed significant changes in the expression levels of genes involved in the DNA damage repair pathway. The sequencing results were verified by Comet DNA, qRT-PCR, WB assays and molecular docking. CONCLUSIONS: Taken together, SGS inhibits the malignant phenotype of HCC cells by down-regulating DNA repair genes and consequently inducing DNA damage.

Effect of sumac powder on clinical symptoms, hyperandrogenism, inflammation, blood glucose, lipid profiles in women with polycystic ovary syndrome: A double-blind randomized clinical trial.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders associated with a high risk of diabetes, atherosclerosis, and cardiovascular disease. The purpose of this study was to determine the effect of sumac powder on clinical symptoms and laboratory parameters in women with PCOS. The double-blind randomized controlled clinical trial was conducted on 88 women with PCOS randomly assigned to the intervention and control groups. The intervention group received three capsules each containing 1 g of sumac powder for 12 weeks. All data and serum levels of sex hormone, hs-CRP, glucose, and lipid profiles were measured at the baseline and at the end of the study. Data were analyzed using SPSS version 25 software. The ANCOVA test results showed that hs-CRP level was significantly reduced in the intervention group (p = .008). Blood glucose and lipid profiles in the intervention group were significantly reduced compared to the placebo group (p < .05). Insulin sensitivity and HDL levels were increased significantly in the Sumac group after the intervention (p < .05). Sumac powder can reduce the inflammatory effects, and glycemic status and lipid profile of polycystic ovaries in affected women, but has no significant effect on anthropometric parameters and sex hormones.
