Distribution of peripheral dendritic cells in patients with HBV infection or spleen and kidney deficiency.

Distribution of peripheral dendritic cells in patients with HBV infection or spleen and kidney deficiency. J Med Virol. 2017 Nov 23;: Authors: Chen W, Wang L, Niu Y, Ji G, Xing L Abstract AIMS: Spleen and kidney deficiency syndrome (SKD), a Traditional Chinese Medicine (TCM) syndrome, is the fundamental mechanisms of TCM. We aim to investigate the distribution of peripheral dendritic cells (DCs) in HBV patients with SKD or non-SKD. METHODS: Peripheral venous blood from patients with HBV infection and healthy volunteers was collected to extract PBMC, and flow cytometry assay was used to measure the distribution of DCs subsets, including myeloid dendritic cells (mDCs) and plasmacytoid dendritic cells (pDCs). RESULTS: For the number of pDCs, it was higher in control group and non-SKD group, compared with HBV infection group and SKD group, respectively. For the number of mDCs, it was higher in control group and the non-SKD group compared to SKD group, while in control group it was higher than both HBeAg positive group and negative group. The number of pDCs in control group and chronic hepatitis B group were higher than HBVcarrier group, and it was higher in control group than both immune tolerance group and inactive group, while in immune clearance group it was higher than immune tolerance group and inactve group. The number of mDCs in control group and immune clearance group were higher than that of immune tolerance group. CONCLUSIONS: There was an obvious correlation between TCM syndromes and immune function in HBV infected patients, the number of pDCs and mDCs of the SKD group was lower than that in non-SKD group. These results provide a new insight into scientific evidence that TCM probably be based. This article is protected by copyright. All rights reserved.

A Strategy for Preparative Separation of 10 Lignans from Justicia procumbens L. by High-Speed Counter-Current Chromatography. Molecules. 2017 Nov 23;22(12): Authors: Jiang J, Dong H, Wang T, Zhao R, Mu Y, Geng Y, Zheng Z, Wang X Abstract Ten compounds, including three lignan glycosides and seven lignans, were purified from Justicia procumbens L. in 8 h using an efficient strategy based on high-speed counter-current chromatography (HSCCC). The two-phase solvent system composed of petroleum-ethyl acetate-methanol-H₂O (1:0.7:1:0.7, v/v) was firstly employed to separate the crude extract (320 mg), from which 19.3 mg of justicidin B (f), 10.8 mg of justicidin A (g), 13.9 mg of 6'-hydroxyjusticidin C (h), 7.7 mg of justicidin E (i), 6.3 mg of lignan J₁ (j) were obtained with 91.3 mg of enriched mixture of compounds a-e. The enriched mixture (91.3 mg) was further separated using the solvent system consisting of petroleum-ethyl acetate-methanol-H₂O (3:3.8:3:3.8, v/v), yielding 12.1 mg of procumbenoside E (a); 7.6 mg of diphyllin-1-O-β-d-apiofuranoside (b); 7.4 mg of diphyllin (c); 8.3 mg of 6'-hydroxy justicidin B (d); and 7.9 mg of diphyllin acetyl apioside (e). The purities of the 10 components were all above 94%, and their structures were identified by NMR and ESI-MS spectra. The results demonstrated that the strategy based on HSCCC for the separation of lignans and their glycosides was efficient and rapid. PMID: 29168751 [PubMed - in process]

Yangxin Tongmai formula ameliorates impaired glucose tolerance in children with Graves' disease through upregulation of the insulin receptor levels.

Yangxin Tongmai formula ameliorates impaired glucose tolerance in children with Graves' disease through upregulation of the insulin receptor levels. Acta Pharmacol Sin. 2017 Nov 23;: Authors: Luo YH, Zhu M, Wang DG, Yang YS, Tan T, Zhu H, He JF Abstract Graves' disease (GD) is the leading cause of hyperthyroidism, and the majority of GD patients eventually develop disorders of glucose handling, which further affects their quality of life. Yangxin Tongmai formula (YTF) is modified from a famous formula of traditional Chinese medicine for the treatment of cardiovascular diseases. In this study we investigated the potential effects of YTF in the treatment of pediatric GD patients with impaired glucose tolerance. Forty pediatric GD patients and 20 healthy children were recruited for this clinical study. Based on the glucose tolerance, the GD patients were divided into two groups: 20 patients displayed impaired glucose tolerance, while the other 20 patients displayed normal glucose tolerance. YTF was orally administered for 60 days. YTF administration significantly ameliorated the abnormal glucose tolerance and insulin sensitivity in the GD patients with impaired glucose tolerance. To determine the molecular mechanisms of this observation, the number of plasma insulin receptors was determined by ELISA. Before treatment, the fasting and postprandial levels of the insulin receptor were significantly lower in patients with impaired glucose tolerance compared with those in patients with normal glucose tolerance and healthy children. After YTF treatment, both the fasting and the postprandial circulating insulin receptor levels were upregulated, and close to those in healthy children. Therefore, YTF is a potential effective treatment to enhance glucose handling in GD children with impaired glucose tolerance. PMID: 29168473 [PubMed - as supplied by publisher]

A newly hybrid anchoring balloon for direct peroral cholangioscopy using an ultraslim upper endoscope.

A newly hybrid anchoring balloon for direct peroral cholangioscopy using an ultraslim upper endoscope. Dig Endosc. 2017 Nov 23;: Authors: Li J, Guo SJ, Zhang JC, Wang HY, Li K, Niu SH Abstract OBJECTIVES: Large impacted or residual invisible common bile duct (CBD) stones after mechanical lithotripsy are challenging. We aimed to evaluate the feasibility and success rate of a new hybrid anchoring balloon-guided direct peroral cholangioscopy (POC) for these conditions, using an ultraslim endoscope. METHODS: Sixty-five patients with large or residual invisible CBD stones for direct POC from July 2012 to July 2016 were identified, including 6 cases in whom an additional interventional procedure was required. There were altogether 55 cases undergoing a procedure with our new device, with a 0.021-inch guidewire tied to a balloon catheter at its distal end in this single-center retrospective study. Technical success, the procedure time, diagnostic and therapeutic efficacy of direct POC, and procedure-related complications were studied. RESULTS: The hybrid anchoring balloon-guided direct POC was successful in 51/55 (92.7%) procedures, including 18 cases in whom the conventional wire-guided method was failed in 25 minutes. The mean time for technical success by our method was 12.4 ± 3.4 minutes. In total, of the 43 cases with previous removal of CBD stones, 7 (16.3%) were found to have residual stones ≥4 mm, excluding 3 cases in whom the direct POC was failed. In other 25 cases for difficult stones, 24 lithotripsies were performed, resulting in 23 complete fragmentation. No significant procedure-related complications were observed. CONCLUSIONS: The new hybrid anchoring balloon device performs well in facilitating direct POC using an ultraslim endoscope for evaluation and extraction of residual or large impacted CBD stones.

Prognostic analysis of different morphology of the necrotic-viable interface in osteonecrosis of the femoral head.

Prognostic analysis of different morphology of the necrotic-viable interface in osteonecrosis of the femoral head. Int Orthop. 2017 Nov 22;: Authors: Wu W, He W, Wei QS, Chen ZQ, Gao DW, Chen P, Zhang QW, Fang B, Chen LL, Li BL Abstract PURPOSE: The purpose of this study was to investigate the collapse progression in different morphologies of the necrotic-viable interface in osteonecrosis of the femoral head (ONFH). METHODS: A total of 168 patients (202 hips) with Association Research Circulation Osseous (ARCO) stage II ONFH were included. Ending with the collapse of the femoral head, all patients received conservative treatment but without surgical intervention and were followed for three to 91 months. Bilateral hip-joint radiographs and magnetic resonance imaging (MRI) were examined, and the largest layer of necrosis within the coronal section of MRI images was selected together with its anteroposterior radiograph to observe the morphology of the necrotic-viable interface. The morphology was divided into four types: I, type transverse; II, type "V"; III, type zigzag; IV, type closed. The collapse rate and the time to collapse in different morphologies were assessed. RESULTS: A total of 120 hips collapsed in two years or less, 61 were type-I, 51 were type-II, and 8 were type-III. Non-collapse occurred in all 17 hips with type-IV ONFH during long-term follow-up. In 202 hips with ARCO stage-II ONFH, the collapse rate in type-I ONFH was significantly higher than that of type-II and type-III ONFH (P < 0.01 for both). The time to collapse was markedly shortened. CONCLUSIONS: The risk of ONFH-induced collapse is influenced by the morphology of the necrotic-viable interface. Effective mechanical support for preventing the collapse of the femoral head is necessary when the morphology of the necrotic-viable interface is type transverse.

Balancing Herbal Medicine and Functional Food for Prevention and Treatment of Cardiometabolic Diseases through Modulating Gut Microbiota.

Balancing Herbal Medicine and Functional Food for Prevention and Treatment of Cardiometabolic Diseases through Modulating Gut Microbiota. Front Microbiol. 2017;8:2146 Authors: Lyu M, Wang YF, Fan GW, Wang XY, Xu SY, Zhu Y Abstract It has become apparent that gut microbiota is closely associated with cardiometabolic diseases (CMDs), and alteration in microbiome compositions is also linked to the host environment. Next generation sequencing (NGS) has facilitated in-depth studies on the effects of herbal medicine and functional food on gut microbiota. Both herbal medicine and functional food contain fiber, polyphenols and polysaccharides, exerting prebiotics-like activities in the prevention and treatment of CMDs. The administrations of herbal medicine and functional food lead to increased the abundance of phylum Bacteroidetes, and genus Akkermansia, Bifidobacteria, Lactobacillus, Bacteroides and Prevotella, while reducing phylum Firmicutes and Firmicutes/Bacteroidetes ratio in gut. Both herbal medicine and functional food interact with gut microbiome and alter the microbial metabolites including short-chain fatty acids (SCFAs), bile acids (BAs) and lipopolysaccharides (LPS), which are now correlated with metabolic diseases such as type 2 diabetes (T2D), obesity and non-alcoholic fatty liver disease (NAFLD). In addition, trimethylamine (TMA)-N-oxide (TMAO) is recently linked to atherosclerosis (AS) and cardiovascular disease (CVD) risks. Moreover, gut-organs axes may serve as the potential strategy for treating CMDs with the intervention of herbal medicine and functional food. In summary, a balance between herbal medicine and functional food rich in fiber, polyphenols and polysaccharides plays a vital role in modulating gut microbiota (phylum Bacteroidetes, Firmicutes and Firmicutes/Bacteroidetes ratio, and genus Akkermansia, Bifidobacteria, Lactobacillus, Bacteroides and Prevotella) through SCFAs, BAs, LPS and TMAO signaling regarding CMDs. Targeting gut-organs axes may serve as a new therapeutic strategy for CMDs by herbal medicine and functional food in the future. This review aims to summarize the balance between herbal medicine and functional food utilized for the prevention and treatment of CMDs through modulating gut microbiota. PMID: 29167659 [PubMed]

Exenatide Inhibits the KCa3.1 Channels of Aortic Vascular Smooth Muscle in Diabetic Rats.

Exenatide Inhibits the KCa3.1 Channels of Aortic Vascular Smooth Muscle in Diabetic Rats. Acta Cardiol Sin. 2017 Nov;33(6):648-655 Authors: Dong P, Liu M, Liu C Abstract Background: KCa3.1 ion channels play an important role during atherosclerosis. We aimed to investigate the effect of exenatide on KCa3.1 expression in aortic vascular smooth muscle cells (VSMCs) of diabetic rats. Methods: Sprague-Dawley rats were randomly divided into normal control (NC), diabetes model (DM), and exenatide treatment (ET) groups. Hematoxylin and eosin and α-actin immunohistochemical staining were used to detect changes in rat aortic vascular smooth muscle. Quantitative RT-PCR and Western blot analysis were used to detect changes in KCa3.1 mRNA and protein levels, respectively. Results: Aortic tissue staining in the DM group revealed an absence of smooth or integrated endothelium, increased smooth muscle cell proliferation in the media, smooth muscle hyperplasia, disorganized smooth muscle cells, and an increased number of collagen fibers, relative to the NC and ET groups. KCa3.1 mRNA expression was higher in the DM group than in the NC and ET groups. Similarly, the KCa3.1 protein level was higher in the DM group than in the NC and ET groups. The KCa3.1 protein level did not significantly differ between the ET and NC groups. Conclusions: Exenatide could inhibit the expression of the KCa3.1 channel in VSMCs of diabetic rats.

Taxonomy and Identification of the Genus Scolopendra in China Using Integrated Methods of External Morphology and Molecular Phylogenetics.

Taxonomy and Identification of the Genus Scolopendra in China Using Integrated Methods of External Morphology and Molecular Phylogenetics. Sci Rep. 2017 Nov 22;7(1):16032 Authors: Kang S, Liu Y, Zeng X, Deng H, Luo Y, Chen K, Chen S Abstract The centipede Scolopendra has important medicinal value and high toxicity, making it to be an interesting subject for evolutionary studies. However, species identification in China is difficult because of limited resource exploration and lack of recent taxonomic revision. To improve the identification and taxonomy of the genus Scolopendra in China, an in-depth investigation was conducted, and an integrated method that combined morphological characteristics with molecular data was applied. The identification key was revised to show the main difference among species. Our results indicated that morphologically-delimited species were consistent with the molecular analysis inferred from the COI sequences with genetic distances and phylogenetic trees. Additional morphometrics of four characteristics provided criteria for shape variation. These results suggested that the members of the genus Scolopendra in China could be delineated as 14 separate species. A new species from Lufeng county, Yunnan province, was proposed according to its characteristics, which was named as S. lufengia sp. nov. Our results comprehensively ascertained the taxonomic status of Scolopendra species in China, explored their phylogenetic relationships, showed a high success in the identification of medicinal centipedes.

Second-Look Arthroscopic Evaluation and Clinical Outcomes of Anatomic Anterior Cruciate Ligament Reconstruction with Autograft and Hybrid Graft: A Retrospective Study.

Second-Look Arthroscopic Evaluation and Clinical Outcomes of Anatomic Anterior Cruciate Ligament Reconstruction with Autograft and Hybrid Graft: A Retrospective Study. Med Sci Monit. 2017 Nov 23;23:5564-5573 Authors: Xu H, Dong J, Xin D, Zhang J, Kang K, Gao S Abstract BACKGROUND Graft choice is very controversial. This study compared the second-look evaluation and clinical outcomes of anatomic ACL-R using a thin autograft versus a thick hybrid graft. MATERIAL AND METHODS Sixty-eight patients who had received ACL-R with hamstring autograft or autograft-allograft hybrid graft accepted second-look arthroscopy were grouped (autograft: n=31, age: 32.8±8.9, Male/Female: 16/15, and hybrid graft: n=37, age: 33.9±8.4, Male/Female: 27/10). Patients were evaluated with the functional score and KT-1000 test before reconstruction. The re-examination and second-look evaluation were performed at 2-year follow-up. Results were compared and further comparisons were made for grafts size >8.5 mm. RESULTS The hybrid group showed thicker graft size and bigger graft occupancy (9.0±0.5 mm vs. 8.5±0.7 mm, P=.003; 80.1±7.0% vs. 69.9±6.9%, P8.5 mm were selected and compared (autograft, n=16; hybrid, n=29). Graft tension and Synovial coverage showed a significant difference (P=.036 and P=.029). The Lysholm, IKDC, and KT-1000 test were significantly superior for the autograft than the hybrid graft (P=.036, P=.004, and P=.003, respectively). CONCLUSIONS A pure autograft is superior to a hybrid graft with same diameter in ACL-R because the augmenting allografts may be null and void. Therefore, a homogenous graft is recommended.

Method for quantitative detection of FAM19A4 by flow cytometry using latex beads as solid carrier.

Method for quantitative detection of FAM19A4 by flow cytometry using latex beads as solid carrier. J Biosci Bioeng. 2017 Nov 19;: Authors: Li T, Wang W, Cheng Y, Han W Abstract FAM19A4 (family with sequence similarity 19 member A4; also TAFA4) is a classical secretory protein expressed mainly in the central nervous system and upregulated significantly in lipopolysaccharide (LPS)-stimulated monocytes and macrophages. It is a novel cytokine ligand of formyl peptide receptor 1 (FPR1), showing chemotactic activities on macrophages and promoting the phagocytosis capacity and the release of reactive oxygen species (ROS) by macrophages upon zymosan stimulation. Based on the same detection principle as ELISA, we developed a sandwich immunoassay for quantitative detection of FAM19A4 in biological fluids by flow cytometry, with latex beads as solid carrier. The method showed good performance in a wide range of 39-10,000 pg/mL and possessed excellent specificity, good precision, and favorable recovery in several different matrices. Native FAM19A4 secreted by phorblo 12-myristate 13-acetate (PMA) and LPS stimulated THP-1 cells could also be detected by this method. This method will be much helpful to FAM19A4 studies.

The efficacy of RGD modified liposomes loaded with vinorelbine plus tetrandrine in treating resistant brain glioma.

The efficacy of RGD modified liposomes loaded with vinorelbine plus tetrandrine in treating resistant brain glioma. J Liposome Res. 2017 Nov 22;:1-31 Authors: Li XT, Tang W, Xie HJ, Liu S, Song XL, Xiao Y, Wang X, Cheng L, Chen GR Abstract Brain glioma is one of the most common and devastating intracranial malignancies with a high mortality. Chemotherapy for brain glioma is not ideal due to blood brain barrier (BBB) and multidrug resistance (MDR). The objectives of the present study were to develop a kind of RGD (Arg-Gly-Asp) tripeptide modified vinorelbine plus tetrandrine liposomes to achieve BBB transportation, MDR reversion and glioma cell targeting simultaneously. The studies were performed on glioma cells, resistant glioma cells and glioma-bearing mice. Results showed that the constructed liposomes with suitable physicochemical properties could significantly enhance the transport across BBB, obviously accumulate in glioma cells, and exhibit evident capabilities in diminishing brain glioma in mice. Action mechanism studies indicated that the enhanced anticancer efficacy could be attribute to the follows: prolonged elimination half-life (7.093 ± 1.311 h); increased AUC0-24 h (28.92 ± 2.66 mg/L*h); transporting across BBB; enhanced cellular uptake; down-regulation on P-gp (0.49 ± 0.06 fold); inducing apoptosis via activating caspase 8, 9 and 3 (2.40 ± 0.22, 3.57 ± 0.29 and 4.33 ± 0.30 folds, respectively). In conclusion, the RGD modified vinorelbine plus tetrandrine liposomes may offer a promising therapeutic strategy for treatment of brain glioma. PMID: 29166813 [PubMed - as supplied by publisher]
