RESUMO
Traditional Chinese medicine has been used to treat diabetic foot ulcer (DFU) for a long time. However, the underlying mechanism of Radix arnebiae seu lithospermi ointment (RAS-ointment) has not been revealed. Effects of RAS-ointment treatment were observed in DFU patients. The endogenous competitive RNA mechanism was constructed based on micro-array sequencing and bioinformatics analysis. RT-PCR was used to detected the expression of genes in DFU ulcerated skins and non-ulcerated skins. Dual luciferase and RT-PCR experiments were used to investigate the endogenous competitive RNA mechanism. Based on micro-array sequencing and bioinformatics analysis, we found that SNHG12/NFYC-AS1, hsa-miR-199a-5p and S100A8/S100A7/XDH might form an endogenous competitive RNA mechanism. RT-PCR assay shown that SNHG12, NFYC-AS1, S100A8, S100A7 and XDH were significantly up-regulated, while hsa-miR-199a-5p was significantly down-regulated in DFU ulcerated skins (N = 10) compared with non-ulcerated skins (N = 10). Dual luciferase and RT-PCR experiments showed that SNHG12 or NFYC-AS1 up-regulated the expression of S100A8, S100A7 and XDH by inhibiting hsa-miR-199a-5p in a direct binding way. After 35 days of RAS-ointment treatment, the wound healing of DFU patients was substantially improved and the expression of S100A7 and XDH were reduced expression in DFU patients. In addition, the monomer composition of RAS-ointment, 49070_FLUKA or auraptenol inhibited the expression of S100A7 and XDH in Te317.sk cells. In conclusion, RAS-ointment may be used as an adjunctive therapy for DFU patients.

The inconsistency of diagnostic criteria for malnutrition has confused clinicians since the 1980s. After the implementation of disease diagnosis related group payment (DRG) in China's public hospitals, the diagnosis of malnutrition and the correct documentation of nutrition-related diagnosis on the front sheet of medical records are related to the correct classification of the disease group and the medical insurance payment. Therefore, the reliable diagnostic criteria for malnutrition, especially disease-related malnutrition, is urgently needed in clinical practice. In September 2018, The global leadership Iinitiative on malnutrition (GLIM) diagnostic criteria consensus was launched. GLIM aimed to provide the explicit and unified diagnostic criteria for malnutrition in adult hospitalized patients. However, GLIM criteria was based on the voting by nutritional experts and was merely a consensus in nature. The clinical validity of GLIM criteria needs prospective verification, i.e., to demonstrate that patients with malnutrition as per GLIM criteria could have improved clinical outcomes with reasonable nutritional interventions. In November 2020, the article titled Nutritional support therapy after GLIM criteria may neglect the benefit of reducing infection complications compared with NRS 2002 was published on the journal Nutrition. It was the first study comparing nutritional risk screening 2002 (NRS 2002) and GLIM malnutrition diagnostic criteria among Chinese patients for the indication of nutritional support therapy. The clinical effectiveness of the two tools was retrospectively verified as well. Here we discussed the key points of this retrospective study, including the critical research methods, to inform the currently ongoing prospective validation of the GLIM malnutrition diagnostic criteria (the item of reduced muscle mass not included).
RESUMO
Acute respiratory infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had caused a global pandemic since 2019, and posed a serious threat to global health security. Traditional Chinese medicine (TCM) has played an indispensable role in the battle against the epidemic. Many components originated from TCMs were found to inhibit the production of SARS-CoV-2 3C-like protease (3CLpro) and papain-like protease (PLpro), which are two promising therapeutic targets to inhibit SARS-CoV-2. This study describes a systematic investigation of the roots and rhizomes of Sophora tonkinensis, which results in the characterization of 12 new flavonoids, including seven prenylated flavanones (1-7), one prenylated flavonol (8), two prenylated chalcones (9-10), one isoflavanone (11), and one isoflavan dimer (12), together with 43 known compounds (13-55). Their structures including the absolute configurations were elucidated by comprehensive analysis of MS, 1D and 2D NMR data, and time-dependent density functional theory electronic circular dichroism (TDDFT ECD) calculations. Compounds 12 and 51 exhibited inhibitory effects against SARS-CoV-2 3CLpro with IC50 values of 34.89 and 19.88 μmol·L-1, repectively while compounds 9, 43 and 47 exhibited inhibitory effects against PLpro with IC50 values of 32.67, 79.38, and 16.74 μmol·L-1, respectively.

Objective:To investigate the impact of nutrition supplementation (whey protein, fish oil and vitamin D) and physical exercise (resistance and aerobic exercise) on muscle mass and body fat metrics among community elderly with sarcopenia.Method:102 eligible sarcopenic participants per inclusion and exclusion criteria were randomized into the control group (routine consultation, n=34) or the groups receiving nutrition supplementation (Nutr, n=34) or nutrition supplementation combined with exercise (Nutr+Ex, n=34) for 12 weeks. Muscle and body fat related indicators were compared across groups pre- and post-intervention. Results:Analysis of covariance showed that all indicators were significantly different between groups (all P<0.05). Further pairwise comparisons showed that compared with controls, patients in Nutr group showed increased appendicular muscle mass (ASM) by 0.837 kg ( P=0.003, 95% CI: 0.301 to 1.372) and decreased fat mass by 2.876 kg ( P<0.01, 95% CI: -3.941 to -1.812), while patients in Nutr+Ex group showed increased ASM by 0.745 kg ( P=0.010, 95% CI: 0.180 to 1.311) and decreased fat mass by 2.928kg ( P<0.01, 95% CI: -4.408 to -1.808). Other muscle-related indicators also increased while fat-related indicators decreased in both Nutr and Nutr+Ex groups. However, there is no significant difference between Nutr and Nutr+Ex groups. Conclusions:Nutrition supplementation and physical exercise contribute to muscle mass and body fat improvement among sarcopenic elderly. Lifestyle intervention based on nutrition intervention is important for the community elderly with sarcopenia.
RESUMO
The waste recycling of lemon peel, as a functional feed additive in aquafeed was evaluated by estimating the effects of fermented lemon peel (FLP) supplementation in diet on growth performance, innate immune responses, and susceptibility to Photobacterium damselae of grouper, Epinephelus coioides. A basal diet was added FLP at 0%, 1%, 3%, and 5%. Four tested diets were each fed to juvenile grouper (initial weight: 15.89 ± 0.10 g, triplicate groups) in a recirculation rearing system for eight weeks. Fish fed diets with 0%-3% FLP exhibited higher (p < 0.05) final weight, weight gain, and feed efficiency than fish fed the 5% FLP-diet. After challenge test, fish fed the 3% FLP-diet appeared the lowest mortality, followed by fish fed the 1% FLP-diet, and lowest in fish fed 0% and 5% FLP-diets. Plasma lysozyme activities were higher in fish fed diets with FLP than in fish fed the FLP-free control diet before challenge test. After challenge, fish fed diets with 1% and 3% FLP showed highest lysozyme activities, followed by fish fed the diet with 5% FLP, and lowest in fish fed the control diet. Hepatic malondialdehyde content was higher in fish fed the control diet than in fish fed diets with 1%-3% FLP. Results found that diets supplemented with 1%-3% fermented lemon peel can enhance lysozyme activity and resistance to pathogen P. damselae of grouper.

Objective: This pilot study of acupuncture primary channel coupling examined the effect of anterior tibialis (AT) muscle activation (Stomach = ST channel distribution muscle) on ipsilateral anterior deltoid shoulder elevation strength (Large Intestine = LI channel distribution muscle). Design: Pilot study: prospective before and after trial, nonblinded. Materials and Methods: Twenty healthy adults ages 20-60 years without shoulder pathology were recruited from our institution. All subjects consented with the IRB-approved minimal risk protocol for this study. Average shoulder elevation break strength (kg) with arm elevated 90° from side was measured by dynamometer over 3 trials for each of 4 conditions: standing (baseline), standing with ipsilateral AT activation, seated with legs dangling ipsilateral AT activation, and seated with legs dangling ipsilateral gastrocsoleus (GS) activation. The main outcome measures were percentage decrement in shoulder elevation strength in AT and GS conditions compared with baseline. Paired t-test with a statistical significance alpha level of 0.05 was used for all statistical analyses. Results: A statistically and clinically significant 9.5%-12.5% (P < 0.001) decrease in shoulder elevation strength was found with ipsilateral AT activation whether in the standing or seated position. Reciprocal inhibition of the AT muscle through GS activation in the seated position produced markedly smaller 3%-4% decreases in shoulder elevation strength from baseline. Conclusions: This study provides quantitative physical examination evidence of LI-ST channel coupling, demonstrating a statistically (P < 0.001) and clinically significant decrement in shoulder elevation strength (9.5%-12.5%) with ipsilateral AT activation. These findings support the acupuncture concept of primary channel coupling, with results suggesting a neural basis for these results rather than from a fascial signaling mechanism.

Extracting the tongue body accurately from a digital tongue image is a challenge for automated tongue diagnoses, as the blurred edge of the tongue body, interference of pathological details, and the huge difference in the size and shape of the tongue. In this study, an automated tongue image segmentation method using enhanced fully convolutional network with encoder-decoder structure was presented. In the frame of the proposed network, the deep residual network was adopted as an encoder to obtain dense feature maps, and a Receptive Field Block was assembled behind the encoder. Receptive Field Block can capture adequate global contextual prior because of its structure of the multibranch convolution layers with varying kernels. Moreover, the Feature Pyramid Network was used as a decoder to fuse multiscale feature maps for gathering sufficient positional information to recover the clear contour of the tongue body. The quantitative evaluation of the segmentation results of 300 tongue images from the SIPL-tongue dataset showed that the average Hausdorff Distance, average Symmetric Mean Absolute Surface Distance, average Dice Similarity Coefficient, average precision, average sensitivity, and average specificity were 11.2963, 3.4737, 97.26%, 95.66%, 98.97%, and 98.68%, respectively. The proposed method achieved the best performance compared with the other four deep-learning-based segmentation methods (including SegNet, FCN, PSPNet, and DeepLab v3+). There were also similar results on the HIT-tongue dataset. The experimental results demonstrated that the proposed method can achieve accurate tongue image segmentation and meet the practical requirements of automated tongue diagnoses.

RESUMO
Objective:This paper systematically reviews the application of telemedicine on glucose control and pregnancy outcome improvement among patients with GDM.Methods:We searched Cochrane Library databases, Scopus, Pubmed, Web of Science, CNKI, Wanfang Data database to collect English or Chinese randomized controlled trials (RCTs) related to the adoption of telemedicine interventions on glucose and clinical outcomes for GDM from January 2000 to June 2020. Literature screening, data extraction and evaluation of the risk of bias were done independently by two reviewers. RevMan 5.4 was conducted for meta-analysis.Results:16 RCTs were identified, with 1859 pregnancies. The meta-analysis found that telemedicine group had significantly reduced fasting blood glucose [MD=-0.41, 95% CI(-0.65, -0.17), P<0.001], 2-hour postprandial blood glucose (2hPBG) [MD=-1.08, 95% CI (-1.44, -0.73), P<0.001]、and HbA1c [MD=-0.73, 95% CI(-0.95, -0.50), P<0.001]. However there were no statistically significant differences in caesarean delivery rate [ OR=0.85,95% CI(0.55,1.31)], insulin adoption rate [ OR=0.94, 95% CI(0.46, 1.91)], macrosomia or large-for-age (LGA) rate [ OR=1.06, 95% CI (0.77, 1.46)], birth weight [MD=-14.10, 95% CI (-45.68, 73.87)], preelampsia or pregnancy-induced hypertension rate [ OR=1, 95% CI (0.51, 1.96)], neonatal hypoglycemia rate [ OR=0.81, 95% CI(0.42, 1.59)], or NICU admission rate [ OR=0.97, 95% CI (0.60, 1.57)] between telemedicine and traditional medicine model. Conclusion:Compared to traditional medicine model, telemedicine has its advantage in glucose control, but achieved similar ability in pregnancy outcome improvement.
RESUMO
BACKGROUND@#Spinal cord injury (SCI) is a worldwide medical concern. This study aimed to elucidate the mechanism underlying the protective effect of hyperbaric oxygen (HBO) against SCI-induced neurologic defects in rats via exploring the stromal cell-derived factor-1 (SDF-1)/CXC chemokine receptor 4 (CXCR4) axis and expression of brain-derived neurotrophic factor (BDNF).@*METHODS@#An acute SCI rat model was established in Sprague-Dawley rats using the Allen method. Sixty rats were divided into four groups (n = 15 in each group): sham-operated, SCI, SCI treated with HBO (SCI + HBO), and SCI treated with both HBO and AMD3100 (an antagonist of CXCR4; SCI + HBO + AMD) groups. The rats were treated with HBO twice a day for 3 days and thereafter once a day after the surgery for up to 28 days. Following the surgery, neurologic assessments were performed with the Basso-Bettie-Bresnahan (BBB) scoring system on postoperative day (POD) 7, 14, 21, and 28. Spinal cord tissues were harvested to assess the expression of SDF-1, CXCR4, and BDNF at mRNA and protein levels, using quantitative real-time polymerase chain reaction, Western blot analysis, and histopathologic analysis.@*RESULTS@#HBO treatment recovered SCI-induced descent of BBB scores on POD 14, (1.25 ± 0.75 vs. 1.03 ± 0.66, P < 0.05), 21 (5.27 ± 0.89 vs. 2.56 ± 1.24, P < 0.05), and 28 (11.35 ± 0.56 vs. 4.23 ± 1.20, P < 0.05) compared with the SCI group. Significant differences were found in the mRNA levels of SDF-1 (mRNA: day 21, SCI + HBO vs. SCI + HBO + AMD, 2.89 ± 1.60 vs. 1.56 ± 0.98, P < 0.05), CXCR4 (mRNA: day 7, SCI + HBO vs. SCI, 2.99 ± 1.60 vs.1.31 ± 0.98, P < 0.05; day 14, SCI + HBO vs. SCI + HBO + AMD, 4.18 ± 1.60 vs. 0.80 ± 0.34, P < 0.05; day 21, SCI + HBO vs. SCI, 2.10 ± 1.01 vs.1.15 ± 0.03, P < 0.05), and BDNF (mRNA: day 7, SCI + HBO vs. SCI, 3.04 ± 0.41 vs. 2.75 ± 0.31, P < 0.05; day 14, SCI + HBO vs. SCI, 3.88 ± 1.59 vs. 1.11 ± 0.40, P < 0.05), indicating the involvement of SDF-1/CXCR4 axis in the protective effect of HBO.@*CONCLUSIONS@#HBO might promote the recovery of neurologic function after SCI in rats via activating the SDF-1/CXCR4 axis and promoting BDNF expression.

RESUMO
BACKGROUND: Recurrent and persistent secondary hyperparathyroidism (SHPT) nodules have an incidence of 10-70% after surgery. The treatment of recurrent and persistent SHPT nodules is a challenge, and surgical resection of difficult-to-reach or post-operative adhesions often fails. PURPOSE: The aim of this research was to study the safety and effectiveness of microwave ablation (MWA) for recurrent and persistent SHPT. MATERIALS AND METHODS: This was a retrospective study of 11 patients enrolled with a total of 16 nodules, and MWA was employed to manage SHPT. The laboratory test results, including the intact parathyroid hormone (iPTH), serum calcium, phosphorus and alkaline phosphatase (ALP) levels, improvement of SHPT-related symptoms after ablation, and complications during and after MWA were recorded and analysed. RESULTS: After ablation the value of iPTH was markedly decreased from 1570 ± 1765 pg/mL to 287 ± 239 pg/mL 1 day after MWA (p < 0.05). The levels of serum calcium and phosphorus decreased from 2.51 ± 0.23 mmol/L to 2.06 ± 0.27 mmol/L (p < 0.001) and 1.80 ± 0.43 mmol/L to 1.48 ± 0.32 mmol/L (p < 0.05), respectively, 1 day after MWA. There was no significant difference in the ALP value before and after MWA (p > 0.05). The clinical symptoms, including ostalgia, pruritus, disability, and restless legs, improved after MWA. Minor complications and side effects encountered during or after MWA include haematoma (1/11, 9%), transient hoarseness (2/11, 18.2%), hypocalcemia (6/11, 54.5%). No major complication occurred. CONCLUSION: MWA may be safe and effective to manage recurrent and persistent SHPT nodules; a definite conclusion needs to expand the sample size with a longer follow-up time.

OBJECTIVE@#To investigate the distribution of pathogens and drug resistance in bile and the association between the pregnane X receptor (PXR) gene polymorphisms, traditional Chinese medicine (TCM) syndromes and the risk of cholesterol gallstone disease (CGD).@*METHODS@#A total of 392 samples were enrolled in this study from January 2014 to February 2015, among which 192 patients were with CGD, and 200 samples were healthy. Strains were isolated and susceptibility testing was the disk diffusion method susceptibility testing. The patients were divided into hepatochlic hygropyrexia, stagnation of liver-qi, and the accumulation of damp. The PXR gene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism. The association between the PXR gene polymorphisms and the risk of CGD was examined by logistic regression analysis.@*RESULTS@#A total of 192 cases were detected in 230 of bile culture pathogens, including Gram-negative bacteria 133 (57.83%), Gram-positive bacteria 76 (33.04%), and fungi 21 (9.13%). The top five pathogens were Escherichia coli, Klebsiella pneumoniae, Enterococcus faecalis, Candida albicans, and Enterococcus feces, of which 110 cases was of single infection, 48 cases of mixed infection of two strains, eight cases of mixed infection of three bacteria. Among 59 Escherichia coli, the yield extended-spectrum beta-lactamases had 40 (67.80%). The hepatochlic hygropyrexia was the most TCM syndrome, followed by stagnation of liver-qi, and the accumulation of damp was least. Different pathogens and the rs6785049 genotypes distributed differently in cholelithiasis patients with different TCM syndromes (P < 0.05). In hepatochlic hygropyrexia patients the Gram-negative bacteria was most. There was significant differences between CGD group and control group in rs6785049 (P < 0.001). Comparison with wild-type portable GG, GA genotype increased the risk of the occurrence of gallstones (OR = 0.40, 95%CI: 0.16-0.79); likewise, carrying the GA+AA genotype also increased the risk (OR = 0.38, 95%CI: 0.19-0.81).

RESUMO
Objective: To investigate the distribution of pathogens and drug resistance in bile and the association between the pregnane X receptor (PXR) gene polymorphisms, traditional Chinese medicine (TCM) syndromes and the risk of cholesterol gallstone disease (CGD). Methods: A total of 392 samples were enrolled in this study from January 2014 to February 2015, among which 192 patients were with CGD, and 200 samples were healthy. Strains were isolated and susceptibility testing was the disk diffusion method susceptibility testing. The patients were divided into hepatochlic hygropyrexia, stagnation of liver-qi, and the accumulation of damp. The PXR gene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism. The association between the PXR gene polymorphisms and the risk of CGD was examined by logistic regression analysis. Results: A total of 192 cases were detected in 230 of bile culture pathogens, including Gram-negative bacteria 133 (57.83%), Gram-positive bacteria 76 (33.04%), and fungi 21 (9.13%). The top five pathogens were Escherichia coli, Klebsiella pneumoniae, Enterococcus faecalis, Candida albicans, and Enterococcus feces, of which 110 cases was of single infection, 48 cases of mixed infection of two strains, eight cases of mixed infection of three bacteria. Among 59 Escherichia coli, the yield extended-spectrum beta-lactamases had 40 (67.80%). The hepatochlic hygropyrexia was the most TCM syndrome, followed by stagnation of liver-qi, and the accumulation of damp was least. Different pathogens and the rs6785049 genotypes distributed differently in cholelithiasis patients with different TCM syndromes (P < 0.05). In hepatochlic hygropyrexia patients the Gram-negative bacteria was most. There was significant differences between CGD group and control group in rs6785049 (P < 0.001). Comparison with wild-type portable GG, GA genotype increased the risk of the occurrence of gallstones (OR = 0.40, 95%CI: 0.16-0.79); likewise, carrying the GA+AA genotype also increased the risk (OR = 0.38, 95%CI: 0.19-0.81). There was no significant differences in rs2276707, rs3814055 site polymorphic loci alleles in CGD group and control group. Conclusions: In the treatment of cholelithiasis, bile samples should be collected for bacterial culture and sensitivity test, and drugs should be strictly chosen based on the results. The rs6785049 polymorphisms in PXR gene may increase the risk of gallstones ontogeny, and gallstones can be early detected and prevented by detecting genotypes. rs6785049 polymorphisms in PXR gene may has relationship with TCM syndromes.
RESUMO
Prostate cancer (PCa) is a common illness for aging males. Lycopene has been identified as an antioxidant agent with potential anticancer properties. Studies investigating the relation between lycopene and PCa risk have produced inconsistent results. This study aims to determine dietary lycopene consumption/circulating concentration and any potential dose-response associations with the risk of PCa. Eligible studies published in English up to April 10, 2014, were searched and identified from Pubmed, Sciencedirect Online, Wiley online library databases and hand searching. The STATA (version 12.0) was applied to process the dose-response meta-analysis. Random effects models were used to calculate pooled relative risks (RRs) and 95% confidence intervals (CIs) and to incorporate variation between studies. The linear and nonlinear dose-response relations were evaluated with data from categories of lycopene consumption/circulating concentrations. Twenty-six studies were included with 17,517 cases of PCa reported from 563,299 participants. Although inverse association between lycopene consumption and PCa risk was not found in all studies, there was a trend that with higher lycopene intake, there was reduced incidence of PCa (Pâ=â0.078). Removal of one Chinese study in sensitivity analysis, or recalculation using data from only high-quality studies for subgroup analysis, indicated that higher lycopene consumption significantly lowered PCa risk. Furthermore, our dose-response meta-analysis demonstrated that higher lycopene consumption was linearly associated with a reduced risk of PCa with a threshold between 9 and 21âmg/day. Consistently, higher circulating lycopene levels significantly reduced the risk of PCa. Interestingly, the concentration of circulating lycopene between 2.17 and 85âµg/dL was linearly inversed with PCa risk whereas there was no linear association >85âµg/dL. In addition, greater efficacy for the circulating lycopene concentration on preventing PCa was found for studies with high quality, follow-up >10 years and where results were adjusted by the age or the body mass index. In conclusion, our novel data demonstrates that higher lycopene consumption/circulating concentration is associated with a lower risk of PCa. However, further studies are required to determine the mechanism by which lycopene reduces the risk of PCa and if there are other factors in tomato products that might potentially decrease PCa risk and progression.

Objective To investigate the therapeutic effects and the possible mechanism of fecal transplantation on rats with Clostridium difficile-associated pseudomembranous colitis. Methods A total of 40 Sprague-Dawley rats were divided into four groups including the healthy control group, model group, fecal transplant treatment group and vancomycin treatment group. Rats in three experimental groups were subcuta-neously injected with clindamycin phosphate (10 mg), followed by treatment with toxin producing Clostridi-um difficile (ACTT43255) enema 24 hours later. The rats in fecal transplant treatment group and vancomy-cin treatment group were respectively treated with fecal suspension and vancomycin one day after modeling. The rats were fasted for one day after the last administration and then executed. The levels of potassium ion ( K) , sodium ion ( Na) , albumin ( ALB) , white blood cells ( WBC) , C-reaction protein ( CRP) , interleu-kin-1β ( IL-1β) , interleukin-10 ( IL-10 ) , interleukin-12 ( IL-12 ) and interleukin-17 ( IL-17 ) as well as the percentage of neutrophils ( N%) in serum samples were detected. The colon tissue samples were collect-ed for pathology examination. Results The rat model of pseudomembranous colitis was successfully estab-lished by subcutaneous injection of clindamycin in combination with toxin-producing Clostridium difficile (ACTT43255) enema. The signs of intestinal inflammation including serious weight loss, remarkably short-ened colon length and significantly increased colon wet weight index were observed in rats from the model group (P<0. 05). Compared with the rats from model group, the rats received fecal transplant showed sig-nificantly increased levels of K, ALB, IL-10 and IL-10/IL-12 in serum and decreased levels of WBC, N%, CRP, IL-1β and IL-17 (P<0. 05). Conclusion Fecal transplantation was proved to be an effective ap-proach for the treatment of pseudomembranous colitis. The therapeutic mechanism might due to its impacts on serum inflammatory factors.
RESUMO
<p><b>OBJECTIVE</b>To explore the pro-inflammatory toxicity of Pinellia pedatiecta, as well as the alum processing method on its pro-inflammatory effect.</p><p><b>METHOD</b>Raphide and agglutinin (PPA) proteins were isolated from fresh P. pedatiecta. The overall animal and cellular level models were applied to investigate the pro-inflammatory effect of raphide and PPA in P. pedatiecta, as well as the impact of the alum processing method on the pro-inflammatory effect, with inflammatory mediators as the index.</p><p><b>RESULT</b>Intraperitoneal injection with P. pedatiecta raphide suspension could significantly increase the content of inflammatory mediators PGE2 and NO. After the alum processing method was adopted, fresh P. pedatiecta and raphide-induced PGE2 and NO release significantly reduced. The stimulation of mice macrophages with P. pedatiecta agglutinin protein could cause the content of dose-dependent inflammatory mediators TNF-alpha and IL-6. After the alum processing method was adopted, PGE2 content in P. pedatiecta agglutinin protein-induced mice peritoneal exudate notably decreased.</p><p><b>CONCLUSION</b>The irritation and toxicity of P. pedatiecta were inflammatory responses in organisms. Its raphide and agglutinin proteins were toxic components, both could cause significant the release of inflammatory medium. The alum processing method could help significantly reduce the pro-inflammatory toxicity of P. pedatiecta.</p>
