Enhancing Diagnostic Precision with Utilizing Combined CRP and IL-6 Testing for Deep Vein Thrombosis Detection Post-Endometrial Cancer Surgery.

Background: Deep vein thrombosis is a common complication after surgery, particularly in cancer patients, necessitating efficient diagnostic methods for timely intervention. Objective: This study aimed to investigate the potential of combining C-reactive protein (CRP) and interleukin-6 (IL-6) tests in diagnosing deep vein thrombosis (DVT) following endometrial cancer surgery. Methods: A cohort of 60 patients who developed DVT post-endometrial cancer surgery and were admitted to the First Hospital of Hebei Medical University between March 2018 and March 2022 constituted the DVT group. Additionally, 60 patients who underwent endometrial cancer surgery during the same period but did not develop DVT formed the non-DVT group. Serum levels of CRP and IL-6 were quantified and compared between the two groups using reliable laboratory techniques. Subsequently, the diagnostic accuracy of single-parameter testing (CRP or IL-6 alone) versus combined testing (CRP and IL-6) for postoperative DVT was assessed. Results: Analysis revealed significantly elevated levels of CRP and IL-6 in the serum of patients in the DVT group compared to those in the non-DVT group (P < .05). Furthermore, combined testing of CRP and IL-6 exhibited heightened sensitivity (0.85%), specificity (0.917%), and area under the curve (AUC) (0.952) compared to single-parameter testing alone, indicating its superiority in diagnosing postoperative DVT. Conclusions: The combination of CRP and IL-6 testing presents a promising diagnostic strategy for identifying postoperative DVT in endometrial cancer patients. Implementing this approach in clinical practice could facilitate early detection and prompt management of DVT, thereby potentially reducing associated morbidity and mortality.

[Network Meta-analysis of Qi-supplementing and Yin-nourishing Chinese patent medicines in treatment of early diabetic nephropathy].

This study aimed to evaluate the efficacy of Qi-supplementing and Yin-nourishing Chinese patent medicine in the treatment of early diabetic nephropathy(DN) by network Meta-analysis to explore the Chinese patent medicine with optimal efficacy and provide references for preventing renal deterioration and delaying the progression of early DN. Eight databases, including CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, and Web of Science, were searched for clinical randomized controlled trial(RCT) of Qi-supplementing and Yin-nourishing Chinese patent medicines in the treatment of early DN. After the literature mee-ting the inclusion criteria was screened, the quality of the literature was evaluated using the Cochrane risk-of-bias tool, and network Meta-analysis was performed using the BUGSnet package in R 4.2.1. Seventy-two research articles with a sample size of 6 344 cases were included, involving eight Chinese patent medicines and seven outcome indicators. The results of the network Meta-analysis showed that(1)in terms of improving urinary albumin excretion rate(UAER), Chinese patent medicines combined with conventional treatment were superior to conventional treatment, and Qiyao Xiaoke Capsules + conventional treatment was optimal.(2)In terms of reducing serum crea-tinine(Scr), Bailing Capsules + conventional treatment had superior efficacy.(3)In terms of reducing 24-hour urine total protein(24hUTP), Shenyan Kangfu Tablets + conventional treatment and Jinshuibao Capsules + conventional treatment had equivalent efficacy, and Shenyan Kangfu Tablets + conventional treatment was superior.(4)In terms of improving fasting blood glucose(FBG), Shenyan Kangfu Tablets + conventional treatment had superior efficacy.(5)In terms of improving total cholesterol(TC), Qiyao Xiaoke Capsules +conventional treatment had superior efficacy.(6)In terms of reducing triglyceride(TG), Bailing Capsules + conventional treatment had superior efficacy.(7)In terms of safety, the occurrence of adverse reactions was reported in seven interventions, but due to the large clinical heterogeneity, the quantitative analysis could not be performed. Overall, Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment were superior to conventional treatment alone in the treatment of early DN. The results showed that Qi-supplementing and Yin-nourishing Chinese patent medicines combined with conventional treatment had good clinical efficacy, and they could significantly reduce renal function indicators such as UAER, Scr, and 24hUTP, and reduce blood sugar and blood lipid, which can provide evidence-based support for the treatment of early DN. However, due to the differences in the quantity and quality of the included research articles, large-sample, multi-center, high-quality studies are still needed for further verification.

Mechanism of Yiqi Yangying Heluo Formula in the Treatment of IgA Nephropathy by Affecting Gd-IgA1 Based on BAFF Molecular Level and T Lymphocyte Immunity.

Background: Galactose-deficient IgA1 (Gd-IgA1) is a critical initiating factor in the pathogenesis of IgA nephropathy (IgAN), which plays an important role in the diagnosis and evaluation of this disease. Moreover, the whole pathogenesis process has an intimate association with the immune response of T and B lymphocytes and their inflammatory factors. There is no specific therapy for IgAN at present. Yiqi Yangyin Formula can significantly reduce urinary protein and hematuria in patients with IgAN. Yiqi Yangying Heluo Formula (YYHF) is optimized on the basis of the above prescription, but its specific mechanism remains to be further studied. Methods: The effect of YYHF on urinary protein and urinary red blood cell count in patients with IgAN was observed by a self-controlled clinical study before and after treatment. On this basis, flow cytometry was used to detect the proportion of T lymphocyte subsets in peripheral blood of patients with IgAN before and after treatment and healthy controls. Meanwhile, the levels of Gd-IgA1, B cell activation factor (BAFF), and their cytokines (IL-4, IL-6, and IL-17) in peripheral blood were detected by enzyme-linked immunosorbent assay. The changes in mechanism-related indicators of the two groups were observed and subject to correlation analysis. Results: (1) Compared with the levels before treatment, 24-hour urinary protein content decreased by 47.7% and urinary red blood cell number decreased by 67% in patients with IgAN intervened by YYHF after 48 weeks of follow-up. (2) Compared with the healthy control group, patients with IgAN showed a significantly increased proportion of Th1 cells, Th17 cells, Th1/Th2, Th1/Treg, Th2/Treg, and Th17/Treg, obviously reduced proportion of Th2 cells and Treg cells, and evidently elevated levels of Gd-IgA1, BAFF, and their cytokines (IL-4, IL-6, and IL-17) in the peripheral blood. (3) Following 48 weeks of follow-up after intervention treatment with YYHF, the levels of Gd-IgA1, BAFF, IL-6, and IL-17 were significantly lower, but the level of IL-4 was higher in peripheral blood of patients with IgAN than those before treatment and after 24 weeks of treatment; simultaneously, the proportion of Th1 cells, Th17 cells, Th1/Th2, Th1/Treg, Th2/Treg, and Th17/Treg decreased while that of Th2 cells and Treg cells increased after 48 weeks of follow-up compared with that before treatment in peripheral blood of patients with IgAN. (4) The results of correlation analysis revealed that the level of Gd-IgA1 in peripheral blood of patients with IgAN was positively correlated with the level of BAFF, as well as the proportion of Th1 cells, Th17 cells, Th1/Th2, IL-6, and IL-17 levels, and negatively correlated with the proportion of Treg cells. In addition, the level of Gd-IgA1 in peripheral blood was positively correlated with proteinuria, yet without correlation with hematuria. Conclusion: YYHF can reduce the quantitative level of 24 h urinary protein and urinary red blood cell count in patients with IgAN. Patients with IgAN have obvious T cell immune imbalance. YYHF can significantly reduce the level of Gd-IgA1 in patients with IgAN, and its mechanism may be explained by the reduced level of BAFF in peripheral blood and improved immune balance of T cells.

Magnesium Isoglycyrrhizinate Attenuates Anti-Tuberculosis Drug-Induced Liver Injury by Enhancing Intestinal Barrier Function and Inhibiting the LPS/TLRs/NF-κB Signaling Pathway in Mice.

Liver injury caused by first-line anti-tuberculosis (anti-TB) drugs accounts for a high proportion of drug-induced liver injury (DILI), and gut microbiota and intestinal barrier integrity have been shown to be involved in the development of DILI. Magnesium isoglycyrrhizinate (MgIG) is the fourth-generation glycyrrhizic acid preparation, which is well documented to be effective against anti-TB DILI, but the underlying mechanism is largely unclear. In the present study, we established a BALB/c mice animal model of the HRZE regimen (39 mg/kg isoniazid (H), 77 mg/kg rifampicin (R), 195 mg/kg pyrazinamide (Z), and 156 mg/kg ethambutol (E))-induced liver injury to investigate the protective effect of MgIG against anti-TB DILI and underlying mechanisms. The results demonstrated that intraperitoneal injection of MgIG (40 mg/kg) significantly ameliorated HRZE-induced liver injury by reducing alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP), and malondialdehyde (MDA) levels and improved liver pathological changes. Species composition analysis of gut microbiota showed that Lactobacillus was the only probiotic that was down-regulated by HRZE and recovered by MgIG. In addition, MgIG attenuated HRZE-induced intestinal pathology, significantly decreased HRZE-induced intestinal permeability by increasing the protein expression of tight junction protein 1 (ZO-1) and occludin, decreased HRZE-induced high lipopolysaccharide (LPS) levels, and further markedly attenuated mRNA expression levels of TNF-α, IL-6, TLR2, TLR4, and NF-κB. Supplementation with Lactobacillus rhamnosus JYLR-005 (>109 CFU/day/mouse) alleviated HRZE-induced liver injury and inflammation in mice. In summary, MgIG effectively ameliorated HRZE-induced liver injury by restoring the abundance of Lactobacillus, enhancing intestinal barrier function, and further inhibiting the activation of the LPS/TLRs/NF-κB signaling pathway. Regulating gut microbiota and promoting the integrity of intestinal barrier function may become a new direction for the prevention and treatment of anti-TB DILI.

Electro-acupuncture for protracted amphetamine abstinence syndrome: study protocol for a pragmatic randomized controlled trial.

BACKGROUND: Protracted amphetamine abstinence syndrome is one of the primary causes of relapse for amphetamine-type drug abusers during withdrawal. However, the importance of the management of protracted amphetamine abstinence syndrome is underestimated. Electro-acupuncture may be a safe and effective alternative therapy for protracted amphetamine abstinence syndrome, but the evidence is limited. METHODS: The study is a prospective, two-center, randomized, waitlist controlled, open-label pragmatic trial. A total of 300 patients with protracted amphetamine abstinence syndrome will be recruited. All participants will be randomly assigned to an electro-acupuncture group or a waitlist group in a 1:1 ratio. Participants in the electro-acupuncture group will receive the electrical-acupuncture treatment. Waitlist group participants will not receive electro-acupuncture treatment but will be assessed at each visit. Treatments will be administered twice a week for a total of 4 consecutive weeks. The primary outcome in this study is the change in the ACSA between baseline (week 0) and the completion of treatment (week 4), and the secondary outcomes are changes in the Hamilton Depression Scale (HAMD), the visual analog scale (VAS), the Hamilton Anxiety Scale (HAMA), the Pittsburgh Sleep Quality Index (PSQI), the Montreal Cognitive Assessment (MoCA), and the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). DISCUSSION: This study will assess the effectiveness of acupuncture in PAAS in real-world settings to provide support for clinical decisions and a basis for subsequent trials comparing acupuncture with other positive regimens.

Comparative effectiveness of glycyrrhizic acid preparations aimed at preventing and treating anti-tuberculosis drug-induced liver injury: A network meta-analysis of 97 randomized controlled trials.

BACKGROUND AND OBJECTIVES: Clinical guidelines and expert consensus do not yet recommend glycyrrhizic acid (GA) preparations, such as compound glycyrrhizin, diammonium glycyrrhizin, magnesium isoglycyrrhizinate (MGIG), et al., for the prevention of anti-tuberculosis(anti-TB) drug-induced liver injury (DILI) due to insufficient evidence. Although these GA preparations are recommended for the treatment of anti-TB DILI, which one performs best is unclear. Previous conventional meta-analyses did not summarize the results of simultaneous comparisons of different glycyrrhizinate preparations. Therefore, we aimed to compare and rank different GA preparations on preventing and treating the anti-TB DILI by network meta-analysis (NMA). METHODS: A systematic search on PubMed, Web of Science, Embase, the Cochrane Library, China National Knowledge Infrastructure, SinoMed, Chongqing VIP and, the Wanfang Database was performed up to December 19, 2020. The literature was screened according to predefined inclusion and exclusion criteria to extract important information. The outcomes were the incidence of liver injury (prevention section) and treatment response rate (treatment section). The NMA was conducted with a random-effects model under the Bayesian framework to calculate risk ratios (RRs) with 95% credible intervals (95% CrIs) using R software (version 3.6.1). RESULTS: From 1,411 publications, we included 97 relevant randomized clinical trials (RCTs) (10,923 participants). In terms of preventing anti-TB DILI (33 RCTs, comprising 5,762 patients), CGC, DGC, DGEC, and DGI, but not CGI, significantly reduced the incidence of liver injury than control group (RRs ranged from 0.26 to 0.58); CGC and DGEC were superior to DGC (RRs = 0.50 and 0.58, respectively). In terms of treating anti-TB DILI (64 RCTs, comprising 5,161 patients), MGIG was most effective among all regimens (RRs ranged from 1.15 to 1.72) while DGC ranked last (RRs ranged from 0.58 to 0.83). CONCLUSIONS: All GA preparations except for CGI were effective in preventing the incidence of anti-TB DILI and CGC was superior to DGC. MGIG seems to be the best choice among all GA preparations for the treatment of anti-TB DILI. Future clinical practice guidelines should factor in these novel findings to improve patient outcomes; however, further high-quality trials are needed to validate these results.

Structural modulation of gut microbiota during alleviation of experimental passive Heymann nephritis in rats by a traditional Chinese herbal formula.

BACKGROUND: Jianpi-Qushi-Heluo formula (JQHF) has been used to treat idiopathic membranous nephropathy (IMN) in hospitals for many years. PURPOSE: Elucidating the protective effect and exploring the potential mechanism of JQHF against IMN. METHODS: Passive Heymann nephritis (PHN) was induced in rats by a single tail vein injection of anti-Fx1A antiserum. Then, the animals were treated with JQHF at 16.2 g/kg or 32.4 g/kg, with benzepril (10 mg/kg) as a positive control. Renal function was evaluated by biochemical measurements and pathological testing. Fecal samples were collected before and after treatment to analyze the gut microbiota composition by shotgun whole metagenome sequencing. RESULTS: JQHF exhibited potent efficacy in ameliorating PHN at both doses, as revealed by decreasing the deposition of IgG and C5b-9, relieving podocyte injury, and reducing glomerular and tubular cell apoptosis. The lower dose was corresponding to the clinical dosage and showed better therapeutic effects than the higher dose. Metagenomic analysis showed that gavage with 16.2 g/kg of JQHF shifted the structure of the gut microbiota in PHN rats and significantly increased the relative abundances of Prevotella copri, Lactobacillus vaginalis and Subdoligranulum variabile. Particularly, S. variabile was strongly negatively correlated with serum levels of TC and TG, the deposition of IgG and C5b-9, and apoptosis of glomerular cells. CONCLUSIONS: The JQHF is an effective agent for the treatment of experimental PHN. The PHN-allevating effect of JQHF is associated with specific alternation of gut microbiota.

Comparison of Biological Characteristics of Different Paranasal Sinus Mucosa in Goats.

BACKGROUND/PURPOSE: Prosthetic implants are the primary treatment for patients with edentulism. This study aims to explore and compare the biological characteristics of mucosal thickness and tensile strength of the paranasal sinuses (maxillary and frontal sinuses) in goats, thereby providing a theoretical basis and guidance for mucosa-related problems involved in maxillary sinus lifting. MATERIALS AND METHODS: The paranasal sinus mucosa (maxillary sinus crest, maxillary sinus floor and frontal sinus mucosa) was obtained from the goats for use in maxillary sinus lifting. The mucosa was made into tissue section specimens and evaluated by a computer with built-in screenshot software and an optical microscope with a graduated eyepiece. A total of 3 readings were randomly selected and recorded. The mucosa was clamped with a laboratory-made clamp device. After connecting the push-pull meter, the mucosa exposed by the inner ring of the clamp device was pressed vertically and uniformly until it ruptured. The strength value was read and recorded. The left and right ends of the mucosa were connected with the clamp device; horizontal tension was applied evenly to the mucosa until the mucosa ruptured. The strength value was read and recorded. The normality test, analysis of variance, LSD pairwise comparison and linear regression were performed for each group of data. RESULTS: The thicknesses of the maxillary sinus crest mucosa, floor mucosa and frontal sinus mucosa in goats were 410.03 ± 65.97 um, 461.33 ± 91.37 um and 216.90 ± 46.47 um, respectively. There were significant differences between the maxillary sinus crest and frontal sinus and the maxillary sinus floor and frontal sinus (P < .05). The range of tensile strength of the maxillary sinus crest mucosa, floor mucosa and frontal sinus mucosa in goats was 0.48 ± 0.10 kg, 0.54 ± 0.11kg and 0.20 ± 0.05kg, respectively. There were significant differences between the maxillary sinus crest and frontal sinus and the maxillary sinus floor and frontal sinus (P < .05). Tensile strength was positively correlated with the thickness of the mucosa of the maxillary and frontal sinuses (P < .05). CONCLUSION: The mucosal thickness and tensile strength of the maxillary sinus crest and floor were greater than those of the frontal sinus mucosa. There was a positive correlation between the tensile strength and the thickness of the mucosa.

Traditional Chinese Medicine in Treating IgA Nephropathy: From Basic Science to Clinical Research.

IgA nephropathy (IgAN) is a major cause of chronic kidney disease (CKD) and end-stage renal disease worldwide. Currently, clinical interventions for IgAN are limited, and many patients seek out alternative therapies such as traditional Chinese medicine (TCM). In the last several years, TCM has accumulated ample application experiences and achieved favorable clinical effects. This article summarizes high-quality research from basic science to clinical applications aimed to provide more evidence-based medicine proof for the clinical treatment of IgAN. In summary, qi and yin deficiency accounted for the largest proportion in IgAN patients, and the treatment of IgAN should be based on supplementing qi and nourishing yin. Further, for patients with severe IgAN, the treatment combination of Chinese and Western medicines is better than pure Chinese medicine or hormone therapy. In addition, the pharmacological mechanism of Chinese herbal medicines is mostly based on restoring the immune function, relieving the inflammation damage, and inhibiting proliferation of the glomerular mesangial cells.

Jianpi Qushi Heluo Formula alleviates renal damages in Passive Hemann nephritis in rats by upregulating Parkin-mediated mitochondrial autophagy.

Jianpi Qushi Heluo Formula (JQHF) is an empirical traditional Chinese medicine prescription for treating Membranous Nephropathy (MN) clinically in China. The therapeutic effect of JQHF has been reported in our previous studies. However, the exact mechanism is still unknown. In this study, by establishing an experimental rat model of MN induced by Sheep anti-rat Fx1A serum, we evaluated the effects of JQHF and Tetrandrine (TET), and Benazepril was used as a positive control. As an autophagy agonist, TET is one of the most active components in JQHF. After 4 weeks, significant kidney damage was observed in the rats in the Model group; comparatively, JQHF markedly decreased 24 h urinary protein, Total Cholesterol (TC), and increased serum total Albumin (ALB). Histology showed that JQHF caused significant improvements in glomerular hyperplasia, renal tubular damage, IgG immune complex deposition, and the ultrastructure of mitochondria in MN rats. Flow cytometry analysis showed that treatment with JQHF reduced the level of reactive oxygen species and apoptosis rate, and upregulated mitochondrial membrane potential. Western blot analysis demonstrated that JQHF could protect against mitochondrial dysfunction and apoptosis by upregulating the expression of PINK1, Mitochondrial Parkin, and LC3-II/I, downregulating the expression of Cytoplasmic Parkin, P62, Cytochrome c, and Caspase-3 in the kidneys of MN rats. From images of co-immunofluorescence, it is observed significantly increase in the co-localization of PINK1 and Parkin, as well as LC3 and mitochondria. Similarly, TET treatment significantly upregulated the mitochondrial autophagy and reduced apoptosis in rats after 4 weeks compared with the model group. Comparatively, the ability of JQHF to alleviate renal damage was significantly higher than those of Benazepril and TET. It was demonstrated that JQHF could delay pathology damage to the kidney and hold back from the progression of MN by inhibiting apoptosis and upregulating the mitochondrial autophagy by PINK1/Parkin pathways.

Rhodiola crenulata extract decreases fatty acid oxidation and autophagy to ameliorate pulmonary arterial hypertension by targeting inhibiton of acylcarnitine in rats.

Pulmonary arterial hypertension (PAH) is a devastating pulmonary circulation disease lacking high-efficiency therapeutics. The present study aims to decipher the therapeutic mechanism of Rhodiola crenulata, a well-known traditional chinese medicine with cardiopulmonary protection capacity, on PAH by exploiting functional lipidomics. The rat model with PAH was successfully established for first, following Rhodiola crenulata water extract (RCE) treatment, then analysis of chemical constituents of RCE was performed, additional morphologic, hemodynamic, echocardiographic measurements were examined, further targeted lipidomics assay was performed to identify differential lipidomes, at last accordingly mechanism assay was done by combining qRT-PCR, Western blot and ELISA. Differential lipidomes were identified and characterized to differentiate the rats with PAH from healthy controls, mostly assigned to acylcarnitines, phosphatidylcholines, sphingomyelin associated with the PAH development. Excitingly, RCE administration reversed high level of decadienyl-L-carnitine by the modulation of metabolic enzyme CPT1A in mRNA and protein level in serum and lung in the rats with PAH. Furthermore, RCE was observed to reduce autophagy, confirmed by significantly inhibited PPARγ, LC3B, ATG7 and upregulated p62, and inactivated LKB1-AMPK signal pathway. Notably, we accurately identified the constituents in RCE, and delineated the therapeutic mechansim that RCE ameliorated PAH through inhibition of fatty acid oxidation and autophagy. Altogether, RCE might be a potential therapeutic medicine with multi-targets characteristics to prevent the progression of PAH. This novel findings pave a critical foundation for the use of RCE in the treatment of PAH.

Antibacterial and anti-inflammatory ultrahigh molecular weight polyethylene/tea polyphenol blends for artificial joint applications.

Periprosthetic joint infection (PJI) is one of the main causes for the failure of joint arthroplasty. In view of the limited clinical effect of oral/injectable antibiotics and the drug resistance problem, there is a pressing need to develop antibacterial implants with therapeutic antimicrobial properties. In this work, we prepared a highly antibacterial ultrahigh molecular weight polyethylene (UHMWPE) implant by incorporating tea polyphenols. The presence of tea polyphenols not only improved the oxidation stability of irradiated UHMWPE, but also gave it the desirable antibacterial property. The potent antibacterial activity was attributed to the tea polyphenols that produced excess intracellular reactive oxygen species and destroyed the bacterial membrane structure. The tea polyphenol-blended UHMWPE had no biological toxicity to human adipose-derived stem cells and effectively reduced bacteria-induced inflammation in vivo. These results indicate that tea polyphenol-blended UHMWPE is promising for joint replacement prostheses with multifunctionality to meet patient satisfaction.

Effects of Jian Pi Qu Shi Formula on intestinal bacterial flora in patients with idiopathic membranous nephropathy: A prospective randomized controlled trial.

BACKGROUND: The incidence of idiopathic membranous nephropathy (IMN) has recently increased remarkably. Immune dysfunction caused by disordered intestinal flora might be an important factor affecting IMN. The Jian Pi Qu Shi Formula (JPQSF) shows promise in treating IMN. Here, we sequenced 16S rRNA genes to compare intestinal flora between patients with IMN and healthy persons. We also conducted a randomized controlled clinical trial to further compare the intestinal flora of patients with IMN treated with traditional Chinese medicine (TCM) and western medicine (WM). METHODS: Among 40 patients with IMN treated at Department of Nephrology in Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine between July 2016 and December 2018, we compared 30 of them with 10 healthy persons (controls). The IMN group was randomly assigned to receive JPQSF (TCM) or immunosuppressant WM therapy in (n = 15 per group) for 6 months. Intestinal microbiota diversity was analyzed using alpha diversity and beta diversity. Intestinal flora that significantly differed between the groups was analyzed using MetaStat. The effects and safety of the therapies were determined based on the values for plasma albumin, 24-h urine protein excretion, serum creatinine, urea nitrogen, estimate glomerular filtration rate (eGFR), complete blood count, and liver enzymes. All data were statistically analyzed using Statistical Package for the Social Sciences (SPSS) 20.0 statistical software. RESULTS: Baseline characteristics did not significantly differ between the IMN and healthy groups, or the TCM and WM groups. After six months of treatment, 24-h urinary protein significantly declined in the TCM and WM groups (before and after treatment: 3.24 ± 1.74 vs. 1.73 ± 1.85 g, P < 0.05 and 3.94 ± 1.05 vs. 1.91 ± 1.18 g, P < 0.05, respectively). Plasma albumin was significantly increased in the TCM group (before vs. after treatment: 32.44 ± 9.04 vs. 39.99 ± 7.03 g/L, P < 0.05), but did not significantly change in the WM group (31.55 ± 4.23 vs. 34.83 ± 9.14 g/L, P > 0.05). Values for urea nitrogen, serum creatinine, and eGFR did not significantly change in either group. The alpha diversity index for intestinal flora differed between the IMN and healthy groups, and the TCM and WM groups. Comparisons of multiple samples (beta diversity) revealed differences in intestinal flora between the IMN and healthy groups, and the TCM and WM groups. The Metastat analysis findings showed that the main genera that differed between the IMN group before treatment and the healthy group were Christensenellaceae_R-7_group, Bifidobacterium (77), Dorea, Escherichia-Shigella, Parabacteroides, Bifidobacterium, and Coprococcus_3. After TCM therapy, the main differential genera were Butyricimonas, Bacteroides, Alistipes, and Lachnospira, and after WM therapy, these were Ruminococcus_2, Lachnospiraceae_ND3007_group, Lachnospira, Bifidobacterium, Alistipes, and [Eubacterium]_ventriosum_group. CONCLUSION: Patients with IMN might have disordered intestinal flora, and JPQSF can regulate intestinal flora in patients with IMN.

Osthole attenuates pulmonary arterial hypertension by the regulation of sphingosine 1-phosphate in rats.

Osthole is observed to have the capacity to treat pulmonary arterial hypertension (PAH) in rats, but molecular mechanism is still unknown. The present study aims to discover therapeutic targets and explore therapeutic mechanism of osthole against PAH from metabolic perspective. A rat model with PAH was successfully established with MCT, following osthole administration, then untargeted metabolomics assay was performed using UPLC-Q-TOF-MS to identify differential metabolites and associated metabolic pathways, at last mechanism investigation was done by qRT-PCR, Western blot and ELISA. Differential metabolites characterized in rats with PAH were mostly assigned to sphingolipid metabolism, synthesis of unsaturated fatty acids, glycolysis, nucleotide metabolism, steroid hormone biosynthesis. Furthermore, osthole reversed high level of S1P by modulating metabolic enzyme Sphk1 in rats with PAH. In addition, osthole inhibited the expression of Sphk1 by downregulating microRNA-21, phosphorylation of Akt, phosphorylation of mTOR in vivo and in vitro. These results demonstrated that metabolomics is a promising approach to discover potential drug target for PAH treatment. Importantly, our findings further elucidated therapeutic mechanism of osthole, a natural product, having a role of metabolic regulator to potentially treat PAH by targeting inhibition of Sphk1/S1P via microRNA-21-PI3K/Akt/mTOR signal pathway. Altogether, this discovery paves a critical foundation for enabling osthole to be a candidate compound to treat PAH.

Shengxuening versus Oral Iron Supplementation for the Treatment of Renal Anemia: A Systematic Review.

Shengxuening (SXN), as an effective supplement to heme-like iron, has been widely used in China to treat renal anemia. However, proof of its use for improving inflammation is scarce in the past decades. This work aimed to evaluate the effectiveness of SXN with inflammatory factors as primary endpoints. By searching PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), China Biology Medicine disc (CBM), VIP Information/ China Science and Technology Journal Database, and WANFANG Database, we identified previous studies that met the inclusion criteria and included them in the systematic review. Analyses were performed using STATA. Nine randomized controlled trials were included in this systematic review. The results revealed that, when compared with oral iron supplementation, SXN can reduce the level of inflammatory factors, including hs-CRP (WMD -1.93 mg/L; 95% CI -2.14 to -1.72), IL-6 (P< 0.05), and TNF-α (P< 0.05), and significantly enhance the level of Hb (WMD 13.40 g/L; 95% CI 12.95 to 13.84), TSAT (WMD 6.88%; 95% CI 6.50 to 7.26), and SF (WMD 38.46 µg/L; 95% CI 23.26 to 53.67). Moreover, SXN exhibits a superior security than oral iron supplementation with less gastrointestinal adverse reactions (RR 0.14; 95% CI 0.06 to 0.32). In patients with renal anemia, SXN is more efective and safer than oral iron supplementation, especially in reducing the level of inflammation.

[Research status and prospects on adenosine receptor mechanism of acupuncture for myocardial ischemia].

The relationship between adenosine receptor (AdoR) and myocardial ischemia (MI), effect of acupuncture for MI and action mechanism of acupuncture improving MI by regulating AdoR are summarized. The existing researches have preliminarily reflected that the improvement of MI treated with acupuncture may be achieved by influencing the expression of AdoR. However, there are still some limitations, e.g. most of the research regimens are single-acupoint, the research results are not entirely consistent and the interaction of AdoRs are ignored, all these need to be further verified and supplemented.

Effects of Niaoduqing Particles () on Delaying Progression of Renal Dysfunction: A Post-trial, Open-Label, Follow-up Study.

OBJECTIVE: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) µmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min-1•1.73 m-2, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) µmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min-1•1.73 m-2, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min-1•1.73 m-2 per year. CONCLUSION: Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).
