Improvement of chronic non-bacterial prostatitis by Jiedu Huoxue decoction through inhibiting TGF-ß/SMAD signaling pathway.

BACKGROUND: Chronic non-bacterial prostatitis (CNBP) accounts for more than 90 % of clinical prostatitis cases, and there is no specific and effective treatment for CNBP. The regulatory role of Jiedu Huoxue decoction (JDHXD)in CNBP remains unclear. We investigated if JDHXD could improve CNBP METHODS: The animal model of CNBP was established by carrageenan injection with 1 % carrageenan (50 µL). The prostate index, epithelial thickness, lumen area, and pain response time were investigated. The apoptosis levels were measured with TUNEL staining and flow cytometry, respectively. Inflammatory factors in the serum were measured with ELISA method. RESULTS: Treatment with JDHXD significantly improve prostate tissues injury in CNBP rats. Some parameters, such as prostate index, and pain response time, reflecting the prostate function were improved by JDHXD. Inhibition of apoptosis, reactive oxygen species (ROS), and inflammatory response were achieved by JDHXD in vivo. JDHXD markedly suppressed the TGF-ß/SMAD signaling pathway, and activation of TGF-ß/SMAD signaling pathway could reverse the improvement of CNBP injury by JDHXD. The anti-inflammatory, anti-oxidative and anti-apoptotic effects of JDHXD were proved. CONCLUSION: JDHXD might improve CNBP injury through suppressing inflammation response, ROS, and apoptosis by targeting TGF-ß/SMAD signaling pathway. This research might provide a new thought for the prevention and treatment of CNBP through inhibiting TGF-ß/SMAD signaling pathway.

[Jiedu Huoxue Decoction improves mitochondrial damage of the prostate in rats with chronic nonbacterial prostatitis].

OBJECTIVE: To explore the possible pathogenesis of chronic nonbacterial prostatitis (CNP) in rats from the perspective of mitochondria, and the interventional effect of Jiedu Huoxue Decoction (JHD) on CNP. METHODS: Forty clean-grade SD male rats were randomly divided into 4 groups of an equal number, sham control, CNP model control, Qianliekang Tablets intervention (QLK) and JHD intervention, those in the former two groups treated intragastrically with normal saline, and those in the latter two with QLK and JHD, respectively, at 2g/kg qd for 30 successive days. Then serum and prostate tissue samples were collected from the rats for calculation of the organ coefficients, HE staining, extraction of mitochondria in the prostate tissue, measurement of the levels of superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-PX) and Na+-K+-ATPase by colorimetric assay, and observation of the ultrastructural changes of the prostatic epithelial cells under the transmission electron microscope (TEM). RESULTS: The organ coefficient of the prostate was significantly higher in the CNP model controls (ï¼»1.95 ± 0.39ï¼½%) than in the sham control (ï¼»1.50 ± 0.42ï¼½%, P < 0.05), QLK (ï¼»1.54 ± 0.32ï¼½%, P < 0.05) and JHD groups (ï¼»1.47 ± 0.53ï¼½%, P < 0.05). TEM showed significant hyperplasia of the interstitial fibrous tissue, glandular structural disorder and inflammatory cell immersion in the CNP model controls, decreased inflammatory cells and reduced hyperplasia of epithelial cells in the acinar and interstitial fibrous tissues in the QLK and JHD groups, but no significant changes in the sham controls. The CNP model controls, compared with the QLK and JHD groups, exhibited remarkably lower levels of SOD (ï¼»17.42 ± 2.91ï¼½ vs ï¼»23.47 ± 5.79ï¼½ and ï¼»22.52 ± 3.88ï¼½ U/mg prot, P < 0.05), GSH-PX (ï¼»38.35 ± 6.98ï¼½ vs ï¼»47.68 ± 10.37ï¼½ and ï¼»89.95 ± 7.65ï¼½ U/mg prot, P < 0.05 or P < 0.01), and Na+-K+-ATPase in the prostatic mitochondria (ï¼»0.98 ± 0.40ï¼½ vs ï¼»1.37 ± 0.29ï¼½ and ï¼»1.85 ± 0.32ï¼½ µmol Pi/mg prot/h, P < 0.05 or P < 0.01), but a higher level of MDA (ï¼»1.70 ± 0.22ï¼½ vs ï¼»0.54 ± 0.14ï¼½ and ï¼»0.59 ± 0.17ï¼½ nmol/mg prot, P < 0.01). Significant mitochondrial damage was observed in the prostate tissue of the CNP model controls, and markedly enhanced mitochondrial autophagy was seen in the JHD group. CONCLUSIONS: Chronic nonbacterial prostatitis induces mitochondrial dysfunction in the prostate of rats, and Jiedu Huoxue Decoction can promote the recovery of mitochondrial function, which may be related to mitochondrial autophagy.

Different Chinese patent medicine therapies for migraine: A protocol for systematic review and network meta-analysis.

BACKGROUND: Migraine is a clinically high incidence rate of neurovascular disease. It is a recurrent headache. It is characterized by nausea, vomiting, fear of voice, and photophobia. Nowadays, a large number of randomized controlled clinical studies have shown that Chinese patent medicine has the advantages of good curative effect and high safety in the treatment of migraine. However, due to the variety of proprietary Chinese medicines, their relative effectiveness and safety have not yet been verified. Therefore, this study will use the network meta-analysis method to verify the effectiveness and safety of different kinds of Chinese patent medicines in the treatment of migraine. METHODS: All randomized controlled trials of Toutongning capsule, Yangxue Qingnao granule, naoxintong capsules, Tianmagouteng granules in the treatment of migraine were searched from PubMed, Cochrane Library, web of science, EMBASE, sinomed, CNKI, Wanfang database, VIP. The retrieval time is from the establishment of the database to November 18, 2020. In order to avoid omission, we will manually retrieve relevant references and conference papers. According to the inclusion and exclusion criteria, we evaluated the quality and risk of all the retrieved literatures. Methodological quality assessment and bias risk will be assessed using the Cochrane bias risk tool. Revman 5.3, WinBUGS 1.4.3, and stata14.2 software will be used for all data analysis. RESULTS: This study will directly or indirectly compare the effectiveness of different interventions on migraine outcome indicators, and rank the effectiveness. The main outcome measures included total effective rate (total effective rate = rocovery + obvious effective + effective/total number of cases × 100%), visual analogue scale (VAS) score, and secondary outcome indicators included analgesic effect evaluation index and quality of life scale. CONCLUSION: To provide evidence for evidence-based medicine and clinical researchers to choose more effective Chinese patent medicines to treat migraine.

Oxidative stress and antioxidant defense in detoxification systems of snake venom-induced toxicity.

BACKGROUND: Snakebites remain a major life-threatening event worldwide. It is still difficult to make a positive identification of snake species by clinicians in both Western medicine and Chinese medicine. The main reason for this is a shortage of diagnostic biomarkers and lack of knowledge about pathways of venom-induced toxicity. In traditional Chinese medicine, snakebites are considered to be treated with wind, fire, and wind-fire toxin, but additional studies are required. METHODS: Cases of snakebite seen at the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine were grouped as follows: fire toxin - including four cases of bites by Agkistrodon acutus and three bites by Trimeresurus stejnegeri - and wind-fire toxin - four cases of bites by vipers and three bites by cobras. Serum protein quantification was performed using LC-MS/MS. Differential abundance proteins (DAPs) were identified from comparison of snakebites of each snake species and healthy controls. The protein interaction network was constructed using STITCH database. RESULTS: Principal component analysis and hierarchical clustering of 474 unique proteins exhibited protein expression profiles of wind-fire toxins that are distinct from that of fire toxins. Ninety-three DAPs were identified in each snakebite subgroup as compared with healthy control, of which 38 proteins were found to have significantly different expression levels and 55 proteins displayed no expression in one subgroup, by subgroup comparison. GO analysis revealed that the DAPs participated in bicarbonate/oxygen transport and hydrogen peroxide catabolic process, and affected carbon-oxygen lyase activity and heme binding. Thirty DAPs directly or indirectly acted on hydrogen peroxide in the interaction network of proteins and drug compounds. The network was clustered into four groups: lipid metabolism and transport; IGF-mediated growth; oxygen transport; and innate immunity. CONCLUSIONS: Our results show that the pathways of snake venom-induced toxicity may form a protein network of antioxidant defense by regulating oxidative stress through interaction with hydrogen peroxide.

Ultrastable Near-Infrared Nonlinear Organic Chromophore Nanoparticles with Intramolecular Charge Transfer for Dually Photoinduced Tumor Ablation.

Near-infrared (NIR) light-responsive nanoparticles (NPs) of organic photosensitizers (PS) hold great promise as phototherapeutic agents for precision photoinduced cancer therapy. However, highly photostable PS nanoparticles with extraordinary photoconversion capacities are urgently desired to fully realize potent phototherapy. Here, NIR nonlinear organic chromophore nanoparticles (NOC-NPs) are shown as single-component PS for dually cooperative phototherapy. Upon 785 nm irradiation, excited NOC-NPs pass through intrinsic intramolecular charge transfer (ICT) channel to generate both abundant singlet oxygen and local hyperthermia, affording synergistic photodynamic therapy (PDT) and photothermal therapy (PTT) for tumor ablation. Furthermore, NOC-NPs exhibit dramatic photostability, enhanced cellular uptake, effective cytoplasmic translocation, as well as preferable tumor accumulation, further ensuring favorable in vivo singlet oxygen generation and hyperthermia for photoinduced tumor ablation. Thus, NOC-NPs may represent novel high-performance PS for synergistic photoinduced cancer therapy, providing new insights into the development of potent PS for clinical translation.

The effect of Jiedu Huoxue decoction on rat model of experimental nonbacterial prostatitis via regulation of miRNAs.

CONTEXT: The underlying mechanisms of Jiedu Huoxue decoction (JDHXD) in treating chronic prostatitis have not been fully explored. OBJECTIVE: This study investigates the miRNAs as potential biomarkers and the effect of JDHXD on the rat model of experimental nonbacterial prostatitis. MATERIALS AND METHODS: Fifty-four Sprague-Dawley male rats were randomly divided into normal control, model, JDHXD low dose (0.5 g/kg/day), medium dose (1 g/kg/day), high dose (2 g/kg/day) and western medicine (cernilton 0.094 g/kg/day) groups, and intragastrically administered once daily for 30 days. The control and model (upon successful establishment) groups received distilled water. Differential expression of miRNAs was analysed with high-throughput miRNA sequencing and validated with qRT-PCR and Northern blot. Prediction of specific target genes and functional enrichment analysis were performed with bioinformatics. RESULTS: LD50 test showed no sign of toxicity with maximum feasible dose 4 g/kg JDHXD. Compared with control, 495 miRNAs showed expression changes in CAP/CPPS rats, of which 211 were significantly different and 37 were prostatic-related. There were 181 differentially expressed miRNAs between the model and high dose JDHXD groups, of which 23 were identical with the control and model groups. Compared with control, miR-146a, miR-423 and miR-205 expression increased significantly in the model group, decreased dose-dependently in the JDHXD groups (p < 0.05), and vice-versa for miR-96 (p < 0.05). The effect of low dose JDHXD was comparable to cernilton (p > 0.05). DISCUSSION AND CONCLUSIONS: Future studies may explore the contributions of the active components in JDHXD. The study design is generalisable. The effect can be repeatedly verified in clinical trials.

Jiedu Huoxue decoction improves inflammation in rat type III prostatitis: The importance of the NF-κB signalling pathway.

This study aimed to investigate the mechanism of Jiedu Huoxue decoction (JDHXD) in type III prostatitis based on the NF-κB signalling pathway. Twenty-six Sprague-Dawley male rats were divided into blank control, model, positive (Prostate Plus), low-dose JDHXD, medium-dose JDHXD and high-dose JDHXD groups. Type III prostatitis rat model was established and confirmed with HE staining. NF-кB P50 and NF-κB P65 expression was detected with immunohistochemistry. NF-κB mRNA expression was detected with qRT-PCR. Protein expression of NF-κB and its inhibitor Iκ-Bα was detected with Western blot. Compared to the model group, a decrease in glandular hyperplasia and inflammation, and in NF-кB P50 and NF-κB P65 expression in the medium- and high-dose JDHXD groups was observed. NF-κB mRNA expression was significantly increased in the model group compared to control (p < 0.05), and significantly decreased in the JDHXD treatment groups compared to model group (p < 0.05). Protein expression of NF-κB was significantly increased in the model and low-dose JDHXD groups compared to control(p < 0.05), and significantly decreased in the medium- and high-dose JDHXD groups compared to model group (p < 0.05). Protein expression of Iκ-Bα was vice versa. JDHXD could be a potential treatment for type III prostatitis via its regulation of NF-κB and Iκ-Bα expression.

MicroRNA-146a and miR-99a are potential biomarkers for disease activity and clinical efficacy assessment in psoriasis patients treated with traditional Chinese medicine.

ETHNOPHARMACOLOGICAL RELEVANCE: Psoriasis is a common chronic inflammatory skin disease. A number of clinical investigations have indicated that traditional Chinese medicine (TCM) is an effective and safe treatment for psoriasis. Zhuhuang Granule (ZG) is a modified formulation of Zhuhuang Decoction, which is used traditionally in China for the treatment of psoriasis in clinical practice. AIM OF THE STUDY: Recent studies have found that microRNAs (miRNAs) play important roles in the pathogenesis of some skin diseases. The objective of our study was to investigate the effect of ZG on the expression of miRNAs in peripheral blood mononuclear cells (PBMCs) from psoriasis patients and to identify specific miRNA biomarkers for psoriasis disease activity and assessment of clinical efficacy. MATERIALS AND METHODS: Twenty-five psoriasis patients and 15 healthy control subjects were recruited to participate in this study from October 2013 to October 2014. Microarray and quantitative real-time PCR (qRT-PCR) were used to measure the global miRNA expression in PBMCs from psoriasis patients and healthy control subjects. We also measured the changes in the Psoriasis Area and Severity Index (PASI) score and miRNA expression of patients before and after treatment with ZG. RESULTS: The microarray results showed that 26 miRNAs were upregulated and 13 miRNAs were decreased in psoriasis patients. qRT-PCR validated 3 upregulated miRNAs (miR-146a, miR-31, miR-192-5p) and 2 downregulated miRNAs (miR-99a, miR-200c) in PBMCs from psoriasis patients compared with healthy controls (p<0.01). Moreover, after 8 weeks of ZG treatment, patients achieved a significant reduction in PASI scores. QRT-PCR analysis indicated that the expression of miR-146a and miR-99a is closely correlated with psoriasis severity (R2=0.772, p<0.01; R2=0.672, p<0.01). CONCLUSION: We suggest that both miR-146a and miR-99a may serve as potential biomarkers for disease activity and clinical efficacy in psoriasis patients treated with ZG.

[Acupoints heat-sensitive moxibustion in the application of traditional Chinese surgery].

Under the guidance of meridian theory, the acupoints heat-sensitive moxibustion is a treatment method which applies moxa stick to perform mild moxibustion at heat-sensitive acupoints, which can arouse the meridian sensation transmission and promote the movement of meridian qi; consequently, the qi can be extended to the diseases. For its many advantages, such as no direct contact on skin, no injuries, no pains, fewer side effects, easy operating and moderate cost, the acupoints heat-sensitive moxibustion is widely accepted in dermatology, male urology disease, rectum and anus diseases and breast diseases. The application and research status of the acupoints heat-sensitive moxibustion in traditional Chinese surgery in recent years is reviewed, and several problems and suggestions in its clinical application and research are proposed, aiming to provide clinical basis for its further development and clinical application in traditional Chinese surgery.
