[Adsorption Properties of Magnetic Phosphorous Camellia Oleifera Shells Biochar to Sulfamethoxazole in Water].

Magnetic phosphorous biochar （MPBC） was prepared from Camellia oleifera shells using phosphoric acid activation and iron co-deposition. The materials were characterized and analyzed through scanning electron microscopy （SEM）， X-ray diffractometry （XRD）， specific surface area and pore size analysis （BET）， Fourier infrared spectroscopy （FT-IR）， and X-ray photoelectron spectroscopy （XPS）. MPBC had a high surface area （1 139.28 m2·g-1） and abundant surface functional groups， and it could achieve fast solid-liquid separation under the action of an external magnetic field. The adsorption behavior and influencing factors of sulfamethoxazole （SMX） in water were investigated. The adsorbent showed excellent adsorption properties for SMX under acidic and neutral conditions， and alkaline conditions and the presence of CO32- had obvious inhibition on adsorption. The adsorption process conformed to the quasi-second-order kinetics and Langmuir model. The adsorption rate was fast， and the maximum adsorption capacity reached 356.49 mg·g-1. The adsorption process was a spontaneous exothermic reaction， and low temperature was beneficial to the adsorption. The adsorption mechanism was mainly the chemisorption of pyrophosphate surface functional groups （C-O-P bond） between the SMX molecule and MPBC and also included hydrogen bonding， π-π electron donor-acceptor （π-πEDA） interaction， and a pore filling effect. The development of MPBC adsorbent provides an effective way for resource utilization of waste Camellia oleifera shells and treatment of sulfamethoxazole wastewater.

A meta-analysis of the efficacy and safety of the traditional Chinese medicine formula Kaixinsan decoction for depression.

BACKGROUND: Kaixinsan (KXS) decoction is a traditional Chinese herbal formulation commonly used to treat depression. This study aimed to evaluate the efficacy and safety of KXS, which is widely used, alone and in combination with other therapies, for the treatment of depression. The main objective was to assess the efficacy and safety of KXS in the treatment of depression as a single agent or in combination with other methods. METHODS: Randomized controlled trials of KXS in the treatment of depression were systematically searched from several Chinese and English databases with no language restriction. Patients in these studies met the relevant diagnostic criteria for depression. Data on HAMD, SDS, practical situations, and occurrence of side effects in the studies were extracted. Finally, the methodological quality and risk of bias of the included studies were assessed using the Jadad scale and Cochrane bias evaluation tool. RESULTS: Twelve studies with 1034 patients were included after screening. The Jadad scale and Cochrane bias evaluation tool indicated that the quality of the studies ranged from fair to good, with 41.7% categorized as good and 58.3% as poor. Egger test and funnel plots showed that the publication bias remain low. CONCLUSION: The results showed that the frequency of side effects in the control group was higher than that in the treatment group, and there was a statistically significant difference. KXS was comparable or superior to antidepressants in treating depression and has fewer side effects. The data analysis showed that effectiveness and other indicators differed significantly by geographic area and dosage form, which has implications for future clinical work.

Noninvasive Diagnostic Technique for Nonalcoholic Fatty Liver Disease Based on Features of Tongue Images.

OBJECTIVE: To investigate a new noninvasive diagnostic model for nonalcoholic fatty liver disease (NAFLD) based on features of tongue images. METHODS: Healthy controls and volunteers confirmed to have NAFLD by liver ultrasound were recruited from China-Japan Friendship Hospital between September 2018 and May 2019, then the anthropometric indexes and sampled tongue images were measured. The tongue images were labeled by features, based on a brief protocol, without knowing any other clinical data, after a series of corrections and data cleaning. The algorithm was trained on images using labels and several anthropometric indexes for inputs, utilizing machine learning technology. Finally, a logistic regression algorithm and a decision tree model were constructed as 2 diagnostic models for NAFLD. RESULTS: A total of 720 subjects were enrolled in this study, including 432 patients with NAFLD and 288 healthy volunteers. Of them, 482 were randomly allocated into the training set and 238 into the validation set. The diagnostic model based on logistic regression exhibited excellent performance: in validation set, it achieved an accuracy of 86.98%, sensitivity of 91.43%, and specificity of 80.61%; with an area under the curve (AUC) of 0.93 [95% confidence interval (CI) 0.68-0.98]. The decision tree model achieved an accuracy of 81.09%, sensitivity of 91.43%, and specificity of 66.33%; with an AUC of 0.89 (95% CI 0.66-0.92) in validation set. CONCLUSIONS: The features of tongue images were associated with NAFLD. Both the 2 diagnostic models, which would be convenient, noninvasive, lightweight, rapid, and inexpensive technical references for early screening, can accurately distinguish NAFLD and are worth further study.

Microplastics in take-out food: Are we over taking it?

Take-out food has become increasingly prevalent due to the fast pace of people's life. However, few study has been done on microplastics in take-out food. Contacting with disposable plastic containers, take-out food may be contaminated with microplastics. In the present study, abundance and characteristics of microplastics in total of 146 take-out food samples including solid food samples and beverage samples (bubble tea and coffee) were determined and identified. The mean abundance of microplastics in take-out food was 639 items kg-1, with the highest value in rice and the lowest value in coffee. Fragments shape, transparent color and sizes ≤ 500 µm were the main characteristics of microplastics in those food, and polyethylene was the main polymer type. Our results indicated that microplastics in take-out food was influenced by food categories and cooking methods, as well as food packaging materials. Approximately 170-638 items of microplastics may be consumed by people who order take-out food 1-2 times weekly.

[Randomized double-blind placebo-controlled trial of Jingfang Granules in treatment of common cold(wind-cold syndrome)].

Jingfang Granules have the effects of inducing sweating to releasing exterior, dispersing wind and dispelling dampness. Modern studies have demonstrated that it has antipyretic and antiviral activities. Therefore, this trial was conducted to evaluate the efficacy and safety of Jingfang Granules in the treatment of common cold(wind-cold syndrome). A total of 138 common cold(wind-cold syndrome) patients meeting the inclusion and exclusion criteria were randomly assigned into the experimental group(n=92) and the placebo group(n=46) at a ratio of 2∶1 and respectively received Jingfang Granules and Jingfang Granules simulation agent. The treatment lasted for 5 d, and the follow-up time was 8 d. Recovery time was employed as the main indicator of efficacy. The median reco-very time of the experimental group was 3.33 d, shorter than that 7.00 d of the placebo group. The efficacy of the experimental group was better than that of the placebo group(P<0.000 1). The major symptom severity score-time AUC of the experimental group was 489.90±206.95, which was smaller than that of the placebo group(763.50±339.53). The recovery rate and marked effective rate of the experimental group were higher than those of the placebo group, The above outcomes were statistically significant between the two groups(P<0.05). The disappearance time and rate of single symptoms including aversion to cold, nasal congestion, runny nose, cough, headache, pharyngeal itching/pain, white sputum, and somatalgia also had significant differences between the two groups(P<0.05), indicating that Jingfang Granules had good performance in alleviating the above symptoms. During the study period, one case of the experimental group had a slight increase in serum creatinine, which returned to the normal level after re-examination. The incidence of adverse reactions was 1.10%, and no serious adverse reaction was found. The two groups had no significant difference in the incidence of adverse reactions. In conclusion, Jingfang Granules can significantly shorten the course of common cold(wind-cold syndrome) and quickly alleviate the clinical symptoms, demonstrating good safety and clinical advantages.

[Stability research of Xiaoer Ganmaoning Oral Liquid based on chromatographic peak matching and image sensory evaluation].

The high performance liquid chromatography(HPLC) characteristic chromatogram of Xiaoer Ganmaoning Oral Liquid(oral liquid for short) was established. The medicinal materials corresponding to characteristic peaks, their index components and ranges of similarity with the reference chromatograms were clarified. The similarity between the characteristic chromatograms of 10 batches of the oral liquid and the reference chromatogram was higher than 0.994. Eighteen characteristic peaks were identified, which were derived from different medicinal materials including Scutellariae Radix, Arctii Fructus, Lonicerae Japonicae Flos, Gardeniae Fructus and Forsythiae Fructus. Further, 11 characteristic peaks were assigned by the comparison with reference substances as chlorogenic acid, neochlorogenic acid, cryptochlorogenic acid, isochlorogenic acid A, isochlorogenic acid C, baicalin, baicalein, wogonin, scutellarin, forsythiaside A and arctiin. Also, the characteristic chromatogram of precipitate in the oral liquid was established, and the similarity between characteristic chromatograms of 10 batches of the precipitate and the reference chromatogram was higher than 0.940. The 14 characteristic peaks originating from the precipitate and those from the oral liquid were consistent in retention time, and the content of all index components in the precipitate was lower than 5% of that in the oral liquid. Moreover, the stability of precipitate during the accelerated stability test was explored with filtration and Matlab-based image sensory evaluation. The precipitate mass and precipitation degree both increased over the stability test duration significantly. The stability of the oral liquid was used as a model system in this study to establish the integrated quality control system which related to medicinal materials, preparations and precipitate with HPLC characteristic chromatograms and image sensory evaluation, which lays a foundation for the exploration of the quantity value transfer of the oral liquid.

Fibronectin-Coated Metal-Phenolic Networks for Cooperative Tumor Chemo-/Chemodynamic/Immune Therapy via Enhanced Ferroptosis-Mediated Immunogenic Cell Death.

The development of nanomedicine formulations to overcome the disadvantages of traditional chemotherapeutic drugs and integrate cooperative theranostic modes still remains challenging. Herein, we report the facile construction of a multifunctional theranostic nanoplatform based on doxorubicin (DOX)-loaded tannic acid (TA)-iron (Fe) networks (for short, TAF) coated with fibronectin (FN) for combination tumor chemo-/chemodynamic/immune therapy under the guidance of magnetic resonance (MR) imaging. We show that the DOX-TAF@FN nanocomplexes created through in situ coordination of TA and Fe(III) and physical coating with FN have a mean particle size of 45.0 nm, are stable, and can release both DOX and Fe in a pH-dependent manner. Due to the coexistence of the TAF network and DOX, significant immunogenic cell death can be caused through enhanced ferroptosis of cancer cells via cooperative Fe-based chemodynamic therapy and DOX chemotherapy. Through further treatment with programmed cell death ligand 1 antibody for an immune checkpoint blockade, the tumor treatment efficacy and the associated immune response can be further enhanced. Meanwhile, with FN-mediated targeting, the DOX-TAF@FN platform can specifically target tumor cells with high expression of αvß3 integrin. Finally, the TAF network also enables the DOX-TAF@FN to have an r1 relaxivity of 6.1 mM-1 s-1 for T1-weighted MR imaging of tumors. The developed DOX-TAF@FN nanocomplexes may represent an updated multifunctional nanosystem with simple compositions for cooperative MR imaging-guided targeted chemo-/chemodynamic/immune therapy of tumors.

The Efficacy and Safety of Acupuncture for Treating Osteoporotic Vertebral Compression Fracture- (OVCF-) Induced Pain: A Systematic Review and Meta-Analysis of Randomized Clinical Trials.

BACKGROUND: Osteoporotic vertebral compression fractures (OVCFs) are common health issues in the elderly that cause chronic pain in over one-third of patients. This study was sought to evaluate the efficacy and safety of acupuncture for alleviating pain caused by OVCFs. METHODS: We performed a search of 8 electronic databases for publications from the inception to 30th March 2021. Eligible studies were randomized clinical trials (RCTs) that evaluated the effect of acupuncture for the treatment of OVCFs. Two investigators evaluated literature quality and extracted data independently. RevMan V.5.4.1 was used for data analyses, with pooled risk estimates presented as mean difference (MD) or relative risk (RR) along with corresponding 95% confidence intervals (CIs), as appropriate. RESULTS: Fourteen RCTs involving 1,130 patients were included in this meta-analysis. Compared with the control group, acupuncture showed a greater benefit on pain reduction caused by OVCFs (1 week: MD = -1.26, 95% CI: (-1.82,-0.70); 1 month: MD = -1.63, 95% CI: (-1.82,-1.43); 6 months: MD = -1.13, 95% CI: (-1.55, -0.70)). Acupuncture treatment was also associated with fewer adverse events, lower ODI index, and higher bone density than the control group (safety: (RR: 0.30, 95% CI: 0.12-0.75); ODI: MD = -3.19, 95% CI: (-5.20, -1.19); bone density: MD = 0.15, 95% CI: (0.05, 0.26)). The GRADE quality of these results was assessed as low or very low. CONCLUSIONS: Compared with the control treatment, acupuncture was more effective and safer in relieving the pain caused by OVCF and made a greater improvement on patient's ODI score and bone density. Given the low level of our study evidence, future high-quality studies are needed to verify our study findings.

Efficacy and safety of Xiyanping injection in the treatment of COVID-19: A multicenter, prospective, open-label and randomized controlled trial.

Xiyanping (XYP) is a Chinese herbal medicine used in the clinic to treat respiratory infection and pneumonia. Recent evidence identified XYP as a potential inhibitor of severe acute respiratory syndrome coronavirus 2, implying XYP as a possible treatment for the coronavirus disease 2019 (COVID-19). Here, we conducted a prospective, multicenter, open-label and randomized controlled trial to evaluate the safety and effectiveness of XYP injection in patients with mild to moderate COVID-19. We consecutively recruited 130 COVID-19 patients with mild to moderate symptoms from five study sites, and randomized them in 1:1 ratio to receive XYP injection in combination with standard therapy or receive standard supportive therapy alone. We found that XYP injection significantly reduced the time to cough relief, fever resolution and virus clearance. Less patients receiving XYP injection experienced disease progression to the severe stage during the treatment process. No severe adverse events were reported during the study. Taken together, XYP injection is safe and effective in improving the recovery of patients with mild to moderate COVID-19. However, further studies are warranted to evaluate the efficacy of XYP in an expanded cohort comprising COVID-19 patients at different disease stages.

Jinfukang inhibits lung cancer metastasis by upregulating CX3CL1 to recruit NK cells to kill CTCs.

ETHNOPHARMACOLOGICAL RELEVANCE: Circulating tumor cells (CTCs) play an important role in tumor metastasis and may be a target for metastasis prevention. The traditional Chinese medicine Jinfukang functions to improve immunity, prevent metastasis, and prolong lung cancer patient survival periods. Yet, whether Jinfukang prevents metastasis by regulating immune cells to clearance CTCs is still unknown. AIM OF THE STUDY: To explore the anti-metastasis mechanism of Jinfukang from the perspective of regulating NK cells to clear CTCs. MATERIALS AND METHODS: CTC-TJH-01 cell was treated with Jinfukang. Cytokine chip was used to detect cytokines in cell culture supernatant. Lymphocyte recruitment assay was detected by Transwell and flow cytometry. Protein expression was analysis by Western blot. LDH kit was used to detect cytotoxicity. NOD-SCID mice used for tail vein injection to study lung metastasis. RESULTS: Jinfukang could promote the expression and secretion of the chemokine CX3CL1 by CTCs. In addition, Jinfukang could promote the recruitment of natural killer (NK) cells by CTCs and significantly increase the cytotoxic effect of NK cells on CTCs. Moreover, Jinfukang could upregulate the expression of FasL and promote the secretion of TNF-α by NK cells and that NK cells could induce the apoptosis of CTCs through the Fas/FasL signaling pathway. Finally, we confirmed that Jinfukang could promote NK cells to kill CTCs and then inhibit lung cancer metastasis in vivo. The above effects of Jinfukang could be partially reversed by an anti-CX3CL1 mAb. CONCLUSIONS: These results suggest that Jinfukang may prevent lung cancer metastasis by enhancing the clearance of CTCs in the peripheral blood by NK cells, providing evidence for the anti-metastasis effect of Jinfukang.

Can Acupuncture Improve Chronic Spinal Pain? A Systematic Review and Meta-Analysis.

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: To investigate the effect and safety of acupuncture for the treatment of chronic spinal pain. METHODS: MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, the WHO Clinical Trial Registry, and the US National Library of Medicine clinical trial registry were searched from January 1, 2000, to November 1, 2019. Randomized controlled trials (RCTs) involving patients with chronic spinal pain treated by acupuncture versus sham acupuncture, no treatment, or another treatment were included. RESULTS: Data was extracted from 22 RCTs including 2588 patients. Pooled analysis revealed that acupuncture can reduce chronic spinal pain compared to sham acupuncture (weighted mean difference [WMD] -12.05, 95% confidence interval [CI] -15.86 to -8.24), mediation control (WMD -18.27, 95% CI -28.18 to -8.37), usual care control (WMD -9.57, 95% CI -13.48 to -9.44), and no treatment control (WMD -17.10, 95% CI -24.83 to -9.37). In terms of functional disability, acupuncture can improve physical function at immediate-term follow-up (standardized mean difference [SMD] -1.74, 95% CI -2.04 to -1.44), short-term follow-up (SMD -0.89, 95% CI -1.15 to -0.62), and long-term follow-up (SMD -1.25, 95% CI -1.48 to -1.03). CONCLUSION: In summary, compared to no treatment, sham acupuncture, or conventional therapy such as medication, massage, and physical exercise, acupuncture has a significantly superior effect on the reduction in chronic spinal pain and function improvement. Acupuncture might be an effective treatment for patients with chronic spinal pain and it is a safe therapy.

Normalization of magnesium deficiency attenuated mechanical allodynia, depressive-like behaviors, and memory deficits associated with cyclophosphamide-induced cystitis by inhibiting TNF-α/NF-κB signaling in female rats.

BACKGROUND: Bladder-related pain symptoms in patients with bladder pain syndrome/interstitial cystitis (BPS/IC) are often accompanied by depression and memory deficits. Magnesium deficiency contributes to neuroinflammation and is associated with pain, depression, and memory deficits. Neuroinflammation is involved in the mechanical allodynia of cyclophosphamide (CYP)-induced cystitis. Magnesium-L-Threonate (L-TAMS) supplementation can attenuate neuroinflammation. This study aimed to determine whether and how L-TAMS influences mechanical allodynia and accompanying depressive symptoms and memory deficits in CYP-induced cystitis. METHODS: Injection of CYP (50 mg/kg, intraperitoneally, every 3 days for 3 doses) was used to establish a rat model of BPS/IC. L-TAMS was administered in drinking water (604 mg·kg-1·day-1). Mechanical allodynia in the lower abdomen was assessed with von Frey filaments using the up-down method. Forced swim test (FST) and sucrose preference test (SPT) were used to measure depressive-like behaviors. Novel object recognition test (NORT) was used to detect short-term memory function. Concentrations of Mg2+ in serum and cerebrospinal fluid (CSF) were measured by calmagite chronometry. Western blot and immunofluorescence staining measured the expression of tumor necrosis factor-α/nuclear factor-κB (TNF-α/NF-κB), interleukin-1ß (IL-1ß), and N-methyl-D-aspartate receptor type 2B subunit (NR2B) of the N-methyl-D-aspartate receptor in the L6-S1 spinal dorsal horn (SDH) and hippocampus. RESULTS: Free Mg2+ was reduced in the serum and CSF of the CYP-induced cystitis rats on days 8, 12, and 20 after the first CYP injection. Magnesium deficiency in the serum and CSF correlated with the mechanical withdrawal threshold, depressive-like behaviors, and short-term memory deficits (STMD). Oral application of L-TAMS prevented magnesium deficiency and attenuated mechanical allodynia (n = 14) and normalized depressive-like behaviors (n = 10) and STMD (n = 10). The upregulation of TNF-α/NF-κB signaling and IL-1ß in the L6-S1 SDH or hippocampus was reversed by L-TAMS. The change in NR2B expression in the SDH and hippocampus in the cystitis model was normalized by L-TAMS. CONCLUSIONS: Normalization of magnesium deficiency by L-TAMS attenuated mechanical allodynia, depressive-like behaviors, and STMD in the CYP-induced cystitis model via inhibition of TNF-α/NF-κВ signaling and normalization of NR2B expression. Our study provides evidence that L-TAMS may have therapeutic value for treating pain and comorbid depression or memory deficits in BPS/IC patients.

Zhujie Hewei Granules Ameliorated Reflux Esophagitis in Rats.

BACKGROUND: Gastroesophageal reflux disease (GERDs) is a common chronic digestive system disease, in which the symptoms of reflux esophagitis (RE) seriously affect the quality of life. AIMS: We aimed to study the therapeutic effect of Zhujie Hewei granules (ZHG) on reflux esophagitis in model rats. MATERIALS AND METHODS: A rat model of RE was established with the steps of half pylorus ligation, cardiotomy, and hydrochloric acid perfusion. The rats in treatment groups were orally administered with 1.30, 2.60, or 5.20 g/kg ZHG once daily for 28 days. Histopathological changes of the esophagus were observed with hematoxylin-eosin staining. The content of total bilirubin and pH in gastric juice was determined. Esophageal mucosal injury was assessed by macroscopic observation scores, mucosal injury index scores, and esophageal inflammation scores. The levels of gastrin (GAS), motilin (MTL), and vasoactive intestinal peptide (VIP) in serum were evaluated by using ELISA kits. RESULTS: After treatment with ZHG, the body weight of RE rats tended to increase drastically, the macroscopic observation scores of the esophagus mucous membrane decreased (P < 0.05), the mucosal injury index scores decreased (P < 0.05), the gastric pH values increased (P < 0.05), and the levels of serum MTL and VIP decreased (P < 0.05). In addition, the high dose of the ZHG-treated group showed lower serum GAS (P < 0.05), while the high and middle doses of the ZHG-treated groups showed lower esophageal inflammation scores (P < 0.05). CONCLUSIONS: ZHG was effective in treating RE in rats due using mechanisms including improving the pH value of gastric contents, decreasing the gastrointestinal hormones (including GAS, MTL, and VIP), and improving the inflammatory damage.

[Strategies of preserving urinary continence in transurethral plasmakinetic enucleation of the prostate for benign prostate hyperplasia].

OBJECTIVE: To explore the strategies of preserving urinary continence in transurethral plasmakinetic enucleation of the prostate (PKEP) for benign prostate hyperplasia (BPH). METHODS: We treated 65 BPH patients by PKEP with preservation of urinary continence (UC-PKEP), which involved protection of the external urethral sphincter in the beginning of surgery, proper preservation of the anterior lobe of the prostate to protect the internal urethral sphincter in the middle, and preservation of the integrity of the bladder neck towards the end. We compared the postoperative status of urinary continence of the patients with that of the 54 BPH cases treated by complete plasmakinetic enucleation of the prostate (Com-PKEP). RESULTS: All the operations were performed successfully with the urinary catheters removed at 5 days after surgery. In comparison with Com-PKEP, UC-PKEP achieved evidently lower incidence rates of urinary incontinence at 24 hours (31.49% vs 13.85%, P <0.05), 1 week (18.52% vs 4.62%, P <0.05), 2 weeks (14.81% vs 3.08%, P <0.05), 1 month (3.70% vs 1.54%, P >0.05), and 3 months (3.70% vs 0%, P >0.05) after catheter removal. Compared with the baseline, the maximum urinary flow rate (Qmax) was significantly improved postoperatively in both the Com-PKEP (ï¼»7.43 ± 3.26ï¼½ vs ï¼»20.58 ± 3.22ï¼½ ml, P <0.05) and the UC-PKEP group (ï¼»8.04 ± 2.28ï¼½ vs ï¼»20.66 ± 3.08ï¼½ ml, P <0.05). CONCLUSIONS: Transurethral PKEP is a safe and effective method for the management of BPH, during which the strategies of avoiding blunt or sharp damage to the external urethral sphincter in the beginning, properly preserving the anterior lobe of the prostate in the middle and preserving the integrity of the bladder neck towards the end may help to achieve rapid recovery of urinary continence.

Δ3,2-Hydroxybakuchiol Attenuates Depression in Multiple Rodent Models Possibly by Inhibition of Monoamine Transporters in Brain.

Δ3,2-Hydroxybakuchiol is isolated from Psoralea corylifolia (L.), which has therapeutic applications in traditional Chinese medicine. Our previous studies have showed that Δ3,2-hydroxybakuchiol inhibited the decreased activity of reserpinized mice, suggestive of its antidepressive potential. In this study, we explored the antidepressant profile of Δ3,2-hydroxybakuchiol in various rodent models and its possible monoamine-modulating mechanism. Δ3,2-Hydroxybakuchiol significantly reduced immobility time of mice in forced swim test and tail suspension test. Δ3,2-Hydroxybakuchiol also significantly increased sucrose consumption in chronic unpredictable mild stress (CUMS) rat model. Furthermore, isotope uptake study showed that Δ3,2-hydroxybakuchiol inhibited the activity of human dopamine transporter (DAT) and norepinephrine transporter (NET) in transporter-overexpressing pheochromocytoma (PC12) cells with IC50 values similar to the potency of bupropion. Microdialysis showed that Δ3,2-hydroxybakuchiol increased dopamine and norepinephrine concentration in rat striatum. In summary, Δ3,2-hydroxybakuchiol exerts antidepressant effects on various types of depression models through a possible mechanism of monoamine transporter inhibition.
