Fire acupuncture for plaque psoriasis case series.

OBJECTIVE: To investigate the clinical efficacy of fire acupuncture (FA) on plaque psoriasis (PP), exploring its suitable syndrome types, in order to achieve better therapeutic effects, accelerate the possibility of psoriasis skin lesion recovery, and provide assistance for clinical treatment. METHODS: A total of 8 patients with PP aged between 18 and 60 years were recruited and treated with FA once a week, and the lesion area and severity index (PASI), visual analog scale and pruritus were measured before, 2, 4 and 8 weeks after treatment and at the follow-up period (week 12), respectively. Visual analog scale, and dermoscopy were used for assessment. RESULTS: All patients showed improvement in pruritus after 1 FA treatment, and lesions were reduced to varying degrees after 2 weeks. Except for patients 5 and 8, who only achieved effective results due to severe disease, all other patients with psoriasis achieved significant results at 8 weeks after treatment. CONCLUSION: FA can significantly control the development of lesions, reduce the symptoms of PP lesions and pruritus, and help prevent psoriasis recurrence.

Reactivation rates of hepatitis B or C or HIV in patients with psoriasis using biological therapies: a systematic review and meta-analysis.

Some biological therapies for psoriasis can cause the reactivation of viral infections. Although recent studies suggest no increased rate of reactivation with biological therapies, some life-threatening cases have been reported. Therefore, this meta-analysis examined the rate of virus reactivation in patients with psoriasis with biological therapies and concurrent hepatitis B virus (HBV), hepatitis C virus (HCV), or human immunodeficiency virus (HIV) infection. PubMed, Embase, and the Cochrane Library were searched for available papers from inception to December 2021. The outcome was the number of patients with virus reactivation after using biological therapies. The random-effect model was used in all analyses. Fourteen reports (1033 patients) were included. The pooled overall rate of virus reactivation was 0.04 (95%CI 0.01-0.09; I2 = 67.7%, P < 0.001). The pooled rates of HBV, HCV, and HIV reactivation were 0.04 (95%CI 0.00-0.10; I2 = 79.9%, P < 0.001), 0.07 (95%CI 0.02-0.14; I2 = 23.7%, P = 0.24), and 0.12 (95%CI 0.00-0.40), respectively. The pooled rates of HBV and HCV reactivation were 0.10 (95%CI 0.03-0.19) and 0.08 (95%CI 0.03-0.15) in Asia, but 0.00 (95%CI 0.00-0.01) and 0.04 (95%CI 0.00-0.21) in Europe. The publication type also influenced the results. The use of biological therapy in patients with psoriasis and HBV, HCV, or HIV infection might be associated with the rate of viral reactivation, but this meta-analysis had limitations, and the evidence might be weak. Nevertheless, it might suggest that at least a consultation with an infection specialist might be warranted in patients with psoriasis in whom biological therapies are considered.

Electroacupuncture remodels the extracellular matrix and promotes synaptic plasticity in a mouse model of depression.

Depression is a chronic and recurrent disease without satisfactory treatment strategies. The therapeutic effect of acupuncture is well known in Traditional Chinese medicine (TCM) due to its unique non-pharmacological nature. Electroacupuncture (EA) for antidepressant therapy has been widely recognized and used in clinic. In this study, the lipopolysaccharide (LPS)-induced depression mice model was used to evaluate the anti-depressant effects of EA treatment. Open Field Test (OFT), Force Swimming Test (FST), and Sucrose Preference Test (SPT) were utilized to detect the ethological alterations in mice. The transcriptology technique was used to evaluate the changes in the hippocampal transcriptome in different groups. We measured protein levels using Western blot and immunohistochemistry. Our data showed that LPS induced ethological alterations in mice and enhanced the gene expression related to gene ontology such as the banded collagen fibril, fibrillar collagen trimer, and collagen fibril organization, pathways such as collagen chain trimerization, collagen biosynthesis and modifying enzymes, and collagen formation. EA could reverse the ECM deposition by inhibiting collagen type Ⅳ trimer, extracellular matrix organization, and collagen formation. EA could enhance the MMP1 and MMP9 expression and promote synaptic plasticity. These data indicated that EA possesses an antidepressant effect, this may achieve by increasing MMPs expression and then remodeling the ECM surrounding the neurons, ultimately repairing neural circuits and promoting synaptic plasticity.

Berberine-Based Heterogeneous Linear Supramolecules Neutralized the Acute Nephrotoxicity of Aristolochic Acid by the Self-Assembly Strategy.

Aristolochic acid (AA) has been reported to cause a series of health problems, including aristolochic acid nephropathy and liver cancer. However, AA-containing herbs are highly safe in combination with berberine (Ber)-containing herbs in traditional medicine, suggesting the possible neutralizing effect of Ber on the toxicity of AA. In the present study, in vivo systematic toxicological experiments performed in zebrafish and mice showed that the supramolecule self-assembly formed by Ber and AA significantly reduced the toxicity of AA and attenuated AA-induced acute kidney injury. Ber and AA can self-assemble into linear heterogenous supramolecules (A-B) via electrostatic attraction and π-π stacking, with the hydrophobic groups outside and the hydrophilic groups inside during the drug combination practice. This self-assembly strategy may block the toxic site of AA and hinder its metabolism. Meanwhile, A-B linear supramolecules did not disrupt the homeostasis of gut microflora as AA did. RNA-sequence analysis, immunostaining, and western blot of the mice kidney also showed that A-B supramolecules almost abolished the acute nephrotoxicity of AA in the activation of the immune system and tumorigenesis-related pathways.

Hyperbaric Oxygen Therapy Versus Intratympanic Steroid for Salvage Treatment of Sudden Sensorineural Hearing Loss: A Systematic Review and Meta-analysis.

OBJECTIVE: The aim of this meta-analysis is to compare the efficacy of hyperbaric oxygen therapy (HBOT) and intratympanic steroids (ITS) as salvage treatment for patients with refractory sudden sensorineural hearing loss (SSNHL). DATA SOURCES: Electronic search was performed in the PubMed, Embase, Cochrane Library, CNKI, and Wan Fang databases to June 1, 2020. METHODS: For each outcome measure, a forest plot was generated and a pooled relative risk (RR) or mean difference (MD) was calculated. Potential publication bias in the meta-analysis was assessed using funnel plot. RESULTS: The numbers of cases with hearing improvements and pure tone averages (PTA) changes after salvage treatment were entered into the R software to calculate the pooled effect of HBOT compared with ITS. When pooling the results of the studies reporting the proportion of patients with hearing improvement, a fixed-effects model was used. We calculated the RR and found no significant difference when HBOT compared with ITS (RR = 1.09, 95% confidence interval [CI]: 0.83-1.42, p = 0.55). With respect to the PTA changes, a fixed-effects model was used. The improvement in the PTA (in dB) was calculated in MD and no significant difference was found between the two groups (MD = 0.55, 95% CI: -1.76-2.86, p = 0.64). CONCLUSION: Both HBOT and ITS offer some benefits for refractory SSNHL patients, and there were no significant differences in hearing outcomes between the two modalities. Future RCTs that include large samples are needed to demonstrate superiority of one of the treatments.

The protective effect of L-glutamine against acute Cantharidin-induced Cardiotoxicity in the mice.

BACKGROUND: Cantharidin (CTD) is a compound which have the potential to be exploited as an antitumor drug, and it has been demonstrated antitumor effects in a variety of cancers. However, the use is limited due to its severe toxicity. It has reported that it can induce fatal cardiac arrhythmias. Fortunately, we found that L-glutamine can alleviate cardiac toxicity caused by cantharidin in mice. METHODS: To investigate the protective effect of L-glutamine, we used a high dose of cantharidin in mice to create a model of cardiotoxicity. In the experimental mice, glutamine was given orally half an hour before they were administrated with cantharidin. The mice of control group were intraperitoneally injected with DMSO solution. The general state of all mice, cardiac mass index, electrocardiogram change and biological markers were determined. Hematoxylin-eosin staining (HE staining) of heart tissue was carried out in each group to reflect the protective effect of glutamine. To investigate the mechanisms underlying the injury and cardio-protection, multiple oxidative stress indexes were determined and succinate dehydrogenase activity was evaluated. RESULT: The results showed that L-glutamine (Gln) pretreatment reduced weight loss and mortality. It also decreased the biological markers (p < 0.05), improved electrocardiogram and histological changes that CTD induced cardiotoxicity in mice. Subsequently, the group pretreated with L-glutamine before CTD treatment increases in MDA but decreases in SOD and GSH, in comparison to the group treated with CTD alone. Besides, succinate dehydrogenase activity also was improved when L-glutamine was administrated before cantharidin compared to cantharidin. CONCLUSIONS: This study provided evidence that L-glutamine could protect cardiac cells against the acute cantharidin-induced cardiotoxicity and the protective mechanism of glutamine may be related to the myocardial cell membrane or the tricarboxylic acid cycle in the mitochondria.

Evaluation of combination effects of Astragalus polysaccharides and florfenicol against acute hepatopancreatic necrosis disease-causing strain of Vibrio parahaemolyticus in Litopenaeus vannamei.

The effects of oral administration of Astragalus polysaccharides (APS) and florfenicol (FFC), singly or in combination, on the survival performance, disease resistance, and immunity of Litopenaeus vannamei were investigated. After challenge with an AHPND-causing strain of Vibrio parahaemolyticus (VPAHPND), shrimp were immediately fed a drug-free diet, diets containing only APS (200 mg·kg-1) or FFC (15 mg·kg-1), or diets containing low-dose (7.5 mg·kg-1 FFC + 100 mg·kg-1 APS), medium-dose (15 mg·kg-1 FFC + 200 mg·kg-1 APS), and high-dose (30 mg·kg-1 FFC+400 mg·kg-1 APS) drug combinations for 5 days. The cumulative shrimp mortality over 5 days after injection of VPAHPND in the APS + FFC combination groups was significantly lower than that in the APS or FFC alone groups (p < 0.05). Immune parameters, including the total hemocyte counts (THCs), hemocyanin (HEM) concentration, antibacterial activity, activity levels of lysozyme (LZM), and levels of acid phosphatase (ACP), alkaline phosphatase (AKP), and phenoloxidase (PO) in cell-free hemolymph, and the expression levels of the immune-related genes anti-lipopolysaccharide factor (ALF), cathepsin B (catB), crustin, lectin (Lec), lysozyme (LZM), and Toll-like receptor (TLR) in hemocytes and hepatopancreas were determined in the shrimp. The values for these immune parameters in the drug combination groups were higher than those in the APS or FFC group (p < 0.05). Finally, in the histological examinations, the histological structural alignment and integrity of the hepatopancreatic tubules in the drug combination groups was better than that in the APS and FFC groups. Under the experimental conditions, dietary APS and FFC had a synergistic effect on immunity and disease resistance among shrimp after VPAHPND infection.

Raman spectrum reveals the cell cycle arrest of Triptolide-induced leukemic T-lymphocytes apoptosis.

Triptolide (TPL), a traditional Chinese medicine extract, possesses anti-inflammatory and anti-tumor properties. Though some research results have implicated that Triptolide (TPL) can be utilized in the treatment of leukemia, it remains controversial about the mechanism of TPL-induced leukemic T-lymphocytes apoptosis. In this study, combining Raman spectroscopic data, principal component analysis (PCA) and atomic force microscopy (AFM) imaging, both the biochemical changes and morphological changes during TPL-induced cell apoptosis were presented. In contrast, the corresponding data during Daunorubicin (DNR)-induced cell apoptosis was also exhibited. The obtained results showed that Raman spectral changes during TPL-induced cell apoptosis were greatly different from DNR-induced cell apoptosis in the early stage of apoptosis but revealed the high similarity in the late stage of apoptosis. Moreover, above Raman spectral changes were respectively consistent with the morphological changes of different stages during TPL-induced apoptosis or DNR-induced apoptosis, including membrane shrinkage and blebbing, chromatin condensation and the formation of apoptotic bodies. Importantly, it was found that Raman spectral changes with TPL-induced apoptosis or DNR-induced apoptosis were respectively related with the cell cycle G1 phase arrest or G1 and S phase arrest.

Effects of postharvest curing treatment on flesh colour and phenolic metabolism in fresh-cut potato products.

The flesh colour and phenolic metabolism in potato tuber during curing and after cut were investigated. Result indicated that postharvest curing not only changed phenolic metabolism during curing, but also improved fresh-cut colour for 12 days after fresh cut. Significantly lower PAL and higher phenolic content and PPO activities during curing treatment and fresh-cut potatoes were detected compared to the control, which lead to the lower browning in the slices from curing treated potatoes. HPLC analysis revealed that amounts of total phenolics, chlorogenic acid, gallic acid and protocatechuic acid were induced by curing and highly accumulated in the curing treated potatoes. Our results demonstrated that phenolic metabolism played an important role in the control of browning of fresh cut potato after curing.
