ABSTRACT

The aim of this paper was to observe the effect of Xinfeng Capsules(XFC)-containing serum on the apoptosis and inflammation of fibroblast-like synoviocytes(FLS) in rheumatoid arthritis(RA) induced by tumor necrosis factor-α(TNF-α), so as to investigate the mechanism of XFC in the treatment of RA. RA-FLS immortalized cell line was established, and XFC drug-containing serum was prepared. CCK-8, ELISA, RT-qPCR, immunofluorescence and TUNEL were used to observe the effect of XFC-containing serum on RA-FLS apoptosis and inflammatory indexes. CCK-8 results showed that the optimal concentration and time of TNF-α on RA-FLS were 10 ng·mL~(-1) and 48 h, respectively; and the optimal concentration and time of XFC on RA-FLS were 6.48 mg·g~(-1) and 72 h, respectively. The results of ELISA showed that compared with RA-FLS group, the expressions of TNF-α, IL-1β, IL-6, IL-8 in TNF-α+RA-FLS group were significantly increased, while the expressions of IL-4 and IL-10 were significantly decreased(P<0.01); after intervention with XFC-containing serum, the expressions of TNF-α, IL-1β, IL-6, IL-8 were significantly decreased, whereas the expressions of IL-4 and IL-10 were significantly increased(P<0.01). The results of RT-qPCR showed that compared with RA-FLS group, the mRNA expressions of Fas, FasL, caspase-3, caspase-8, Bax, Bcl-X1 in TNF-α+RA-FLS group were significantly decreased, while the mRNA expression of Bcl-2 was significantly increased(P<0.001); after intervention with XFC-containing serum, the mRNA expressions of Fas, FasL, caspase-3, caspase-8, Bax, Bcl-X1 were significantly increased, whereas the mRNA expression of Bcl-2 was significantly decreased(P<0.01). The results of immunofluorescence showed that compared with RA-FLS group, the protein expressions of caspase-3 and Bax in TNF-α+RA-FLS group was significantly lower than those in RA-FLS group(P<0.05); after intervention with XFC-containing serum, the protein expressions of caspase-3 and Bax were significantly increased, whereas the protein expression of Bcl-2 was significantly decreased(P<0.05). TUNEL results showed that compared with RA-FLS group, the apoptosis of TNF-α+RA-FLS group was decreased(P<0.05); after intervention with XFC-containing serum, the apoptosis was significantly increased(P<0.05). One of the mechanisms of XFC in the treatment of RA is to promote the apoptosis of RA-FLS and inhibit its inflammatory reaction.

ABSTRACT

OBJECTIVE@#To study the influencing factors for the clinical effect of bronchoalveolar lavage (BAL) in children with Mycoplasma pneumoniae pneumonia (MPP) and atelectasis.@*METHODS@#A total of 75 children with MPP and atelectasis were divided into a good response group with 51 children and a poor response group with 24 children according to the clinical effect of BAL treatment. LASSO logistic regression analysis was used to investigate the factors influencing the clinical effect of BAL treatment. The receiver operating characteristic (ROC) curve and restricted cubic spline model analysis were used to evaluate the value of the course of the disease at the time of BAL treatment in predicting the clinical effect of BAL treatment.@*RESULTS@#Compared with the good response group, the poor response group had a significantly lower percentage of lymphocytes in bronchoalveolar lavage fluid, a significantly higher proportion of children with atelectasis of two or more lung lobes or stenosis of the bronchial cavity or opening caused by inflammation, and a significantly longer course of the disease at the time of BAL treatment and azithromycin treatment (P<0.05). The LASSO logistic regression analysis showed that a prolonged course of the disease at the time of BAL treatment (OR=1.23), atelectasis of two or more lung lobes (OR=11.99), and stenosis of the bronchial cavity or opening caused by inflammation (OR=5.31) were independent risk factors for poor clinical effect of BAL treatment (P<0.05). The ROC curve analysis showed that the course of disease of ≥11.5 days at the time of BAL treatment suggested a poor clinical effect of BAL treatment, with a sensitivity of 91.7% and a specificity of 54.9%. The restricted cubic spline model analysis showed that there was a non-linear dose-response relationship between the course of disease at the time of BAL treatment and the clinical effect of BAL treatment (P<0.05).@*CONCLUSIONS@#Early BAL treatment may have a good clinical effect in children with MPP and atelectasis. Atelectasis of two or more lung lobes and inflammation-induced stenosis of the bronchial cavity or opening shown under bronchoscope may indicate a poor clinical effect of BAL treatment.

ABSTRACT

Abstract  Hematopoietic stem cells (HSCs), as a kind of adult stem cell, is first used in clinical practice. It has been widely used in hematopoietic stem cell transplantation and has broad application prospects in the field of gene therapy. However, the shortage of HSC is still the main bottleneck restricting the clinical application of HSC transplantation, especially cord blood HSC transplantation. With the continuous improvement of the concept of HSC and the in-depth study of the molecular mechanism regulating HSC self-renewal and differentiation, it have been explored that a variety of strategies for ex vivo expansion of HSC, such as adding small molecule compounds in vitro culture system, simulating bone marrow microenvironment, regulating HSC metabolism and biomaterial-based amplification methods. In this review, recent advances in research of ex vivo expansion strategy of HSC are summarized and discussed.

ABSTRACT

There are many different opinions on dose conversion of famous classical formulas from Treatise on Febrile Diseases or Synopsis of the Golden Chamber, which has become a difficult point in research and development of famous classical formulas. At present, the clinical application dose of Banxia Houpotang is similar to the viewpoint that 1 Liang is equivalent to 3 g, in order to provide scientific basis for this conversion method, this paper systematically evaluated the effectiveness of Banxia Houpotang in intervening globus hystericus. Randomized controlled trials (RCTs) of Banxia Houpotang in intervening globus hystericus from CNKI, VIP, Wanfang Data, China Biology Medicine (CBM), Web of Science and PubMed databases were collected online, the retrieval time was from inception to April 1, 2019. Two reviewers independently screened the literature, extracted the data and assessed the risk of bias of the included studies. Then, Meta analysis was performed by RevMan 5.3 software. A total of 17 RCTs involving 1 575 patients were included. The effective rate [relative risk (RR)=1.24, 95%confidence interval (CI) (1.18, 1.30), P<0.000 01] and the curative rate [RR=1.76, 95%CI (1.45, 2.15), P<0.000 01] of Banxia Houpotang in intervening globus hystericus were all better than the control group. Current evidence shows that Banxia Houpotang under the conversion of 3 g in 1 Liang has a significant effect on intervention of globus hystericus. Due to the limitations of quantity and quality of the included studies, the above conclusions need to be verified by more high-quality studies, but the author suggests that such dose conversion should be considered in the research and development of famous classical formulas.

ABSTRACT

To evaluate the effect of traditional Chinese medicine(TCM) invigorating spleen unit therapy on inflammatory markers of osteoarthritis(OA) patients by random walk model. The patient information was collected by the data processing system of medical records of the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine. In-patient information of the department of rheumatology of the hospital between June 2012 and December 2016 was collected and summarized. Based on the use of traditional Chinese medicine decoction and hospital-prepared compound Qiyi Capsules(Xinfeng Capsules),the patients were divided into the unit therapy group and the simple endotherapy group. The random walk model was used to evaluate the effect of traditional Chinese medicine invigorating spleen unit therapy on TCM spleen therapy unit(ESR) and high sensitive C reactive protein(hs-CRP). A total of 3 517 cases of OA patients met the study requirements. The simple endotherapy group had 1 771 cases(50. 36%),while the unit therapy group had 1 746 cases(49. 64%). The baseline data analysis showed that the general information of the cases,the TCM oral intake frequency and the core prescription information had no statistically significant difference,with comparability. The unit therapy group showed the maximum ESR stochastic volatility at 924,walking step number of 1 771,forward walking growth rate at 0. 264 5,ratio at3. 78,random fluctuation power law at 0. 306 5± 0. 076 8,positive increase rate of comprehensive evaluation index at 0. 264 5,and comprehensive evaluation index record number of 1 771; whereas the simple endotherapy group showed the maximum ESR random fluctuation value at 478,walking step number of 1 399,forward walking growth rate at 0. 152 4,ratio at 6. 56,random fluctuation power law at 0. 347 4±0. 101 7,positive increase rate of comprehensive evaluation index at 0. 152 4,and comprehensive evaluation index record number of 1 399. The unit therapy group showed the maximum hs-CRP random fluctuation value at 391,walking step number of1 081,forward walking growth rate at 0. 178 1,ratio at 5. 62,random fluctuation power law at 0. 343 6±0. 094 7,positive increase rate of comprehensive evaluation index at 0. 178 1,and comprehensive evaluation index record number of 1 081; while the simple endotherapy groups showed the maximum hs-CRP random fluctuation value at 210,walking step number of 797,forward walking growth rate at0. 113 2,ratio at 8. 83,random fluctuation power law at 0. 382 6±0. 109,positive increase rate of comprehensive evaluation index at0. 113 2,and comprehensive evaluation index record number of 797. According to our department of rheumatism,there was a longrange correlation between the two groups in the comprehensive evaluation index and the intervention measures. TCM spleen strengthening unit therapy has a better effect in alleviating the inflammatory index of OA than traditional Chinese medicine.

ABSTRACT

The effect of triptolide( TP) on VEGFA,SDF-1,CXCR4 pathway were investigated in vitro to explore the mechanism in improving platelet activation in patients with ankylosing spondylitis( AS). Peripheral blood mononuclear cells( PBMC) were used for the experiment and divided into 4 groups: normal group( NC),model group( MC),triptolide group( TP),and AMD3100 group. The optimal concentration of TP was measured by the MTT method. The expressions of TNF-α,IL-1β,IL-4,IL-10,VEGFA and VEGFR were detected by ELISA. The expressions of SDF-1,CXCR4 and VEGFA were detected by real-time quantitative PCR( RT-qPCR).The expressions of SDF-1,CXCR4,VEGFA and VEGFR were detected by Western blot. The expression levels of CD62 p,CD40 L and PDGFA were detected by immunofluorescence. MTT results showed that medium-dose TP had the strongest inhibitory effect on cells at24 h. The results of ELISA and PCR showed that TP inhibited mRNA expressions of IL-1β,TNF-α,VEGFA,VEGFR and SDF-1,CXCR4 and VEGFA. The results of Western blot indicated that TP inhibited SDF-1,CXCR4 and VEGFA,VEGFR protein expressions; immunofluorescence results indicate that TP can inhibit the expressions of CD62 p,CD40 L,PDGFA. TP may regulate platelet activation by down-regulating SDF-1,CXCR4,VEGFA and VEGFR mRNA expressions,thereby down-regulating IL-1β and TNF-αexpressions,and up-regulating the expressions of IL-4 and IL-10 cytokines.

ABSTRACT

This paper aims to investigate the effect of oral administration of Tripterygium Glycosides Tablets combined with traditional Chinese medicine on immune inflammatory index in patients with rheumatoid arthritis,in order to explore the compatibility mode of traditional Chinese medicine in the treatment of rheumatoid arthritis. Medical records of hospitalized patients with rheumatology at the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from June 2012 to December 2017 were collected. The combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine was adopted for the experimental group,while the simply administration of Tripterygium Glycosides Tablets were adopted for the control group. SPSS 21. 0 was used to analyze the changes of general conditions and immune inflammatory metabolic indexes in the two groups of RA patients. The association rules were analyzed by SPSS Clementine 14. 2 software Apriori module,and the random walk model was evaluated by ORACLE 10 g tool. The results showed that a total of 1 220 patients with rheumatoid arthritis met the requirements of this study,including 322 in the experimental group and 898 in the control group. Before treatment,there was no significant difference in age and duration between the two groups. The difference value of Ig A,Ig G,RF,CCP-AB,hs-CRP and ESR in the two groups of RA patients decreased before and after treatment,and the experimental group was superior to the control group in reduction of Ig A,Ig G,RF,CCP-AB,hs-CRP and ESR.The control group was superior to the experimental group in reduction of Ig M( P<0. 01 or P<0. 05). Compared with before treatment,ALT,AST,ALP,GGT,CREA,BUN,b-MG,MA,TRU and Ig U all increased,with statistically significant differences( P<0. 01).The UA of the two groups of RA patients decreased after treatment,with statistically significant differences( P<0. 01). The experimental group was superior to the control group in reduction of UA,with statistically significant differences( P < 0. 05 or P < 0. 01). The herbs adopted in the prescriptions of 1 220 patients were mainly classified into four categories,namely spleen-sweating herbs,blood-activating and stasis-relieving herbs,phlegm and phlegm-relieving herbs,and heat-clearing and antidote herbs. The results of association rule analysis indicated a significant correlation between the single-flavored Tripterygium Glycosides Tablets,oral Chinese medicine and immune inflammation,and improvement of liver and kidney function indexes. The results of the random walk model analysis indicated that the experimental group's Ig M and hs-CRP were superior to those of the control group in terms of random fluctuation maximum,walking positive growth rate,comprehensive evaluation index increasing rate,comprehensive improvement rate,comprehensive evaluation index recording times,and expected improvement value. The results of this study showed that the single administration of Tripterygium Glycosides Tablets can effectively improve the immune inflammatory metabolic index of patients with rheumatoid arthritis,and the combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine could alleviate the immune inflammatory index of RA patients and reduce liver and kidney dysfunction compared with simple oral administration. The comprehensive evaluation Ig M and hs-CRP in the group of combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine were better than those in the group of the Tripterygium Glycosides Tablets. There was a long-term correlation between the comprehensive evaluation index and the intervention measures of the two groups of patients.

ABSTRACT

Aim To discuss the neuroprotection of an-tioxidant α-phenyl-N-tert-butyl nitrone ( PBN) in Par-kinson's disease ( PD) model. Methods The neuro-protective effects of PBN was explored on 1-methyl-4-phenylpyridinium/1-methyl-4-phenyl-1,2,3,6-tetrahy-dropyridine ( MPP+/MPTP ) induced PD models through a chemical releasing of free radicals in neurons and in vivo. Results PBN significantly scavenged chemical derived free radicals, reduced MPP+induced SH-SY5Y injury and enhanced neurons' viability. In MPTP induced PD model, PBN significantly enhanced the number of tyrosine hydroxylase ( TH)-positive do-pamine ( DA) neurons in the substantia nigra, restored the expression of Nrf2 and HO-1, and raised striatal contents of DA and its metabolites. Conclusion PBN has a potent neuroprotective effect against MPP+/MPTP induced PD models.

ABSTRACT

Tianma(the tuber of Gastrodia eleta) is a widely used and pricy Chinese herb. Its counterfeits are often found in herbal markets, which are the plant materials with similar macroscopic characteristics of Tianma. Moreover, the prices of Winter Tianma(cultivated Tianma) and Spring Tianma(mostly wild Tianma) have significant difference. However, it is difficult to identify the true or false, good or bad quality of Tianma samples. Thus, a total of 48 Tianma samples with different characteristics(including Winter Tianma, Spring Tianma, slice, powder, etc.) and 9 plant species 10 samples of Tianma counterfeits were collected and analyzed by HPLC-DAD-MS techniques. After optimizing the procedure of sample preparation, chromatographic and mass-spectral conditions, the HPLC chromatograms of all those samples were collected and compared. The similarities and Fisher discriminant analysis were further conducted between the HPLC chromatograms of Tianma and counterfeit, Winter Tianma and Spring Tianma. The results showed the HPLC chromatograms of 48 Tianma samples were similar at the correlation coefficient more than 0.848(n=48). Their mean chromatogram was simulated and used as Tianma HPLC fingerprint. There were 11 common peaks on the HPLC chromatograms of Tianma, in which 6 main peaks were chosen as characteristic peaks and identified as gastrodin, p-hydroxybenzyl alcohol, parishin A, parishin B, parishin C, parishin E, respectively by comparison of the retention time, UV and MS data with those of standard chemical compounds. All the six chemical compounds are bioactive in Tianma. However, the HPLC chromatograms of the 10 counterfeit samples were significantly different from Tianma fingerprint. The correlation coefficients between HPLC fingerprints of Tianma with the HPLC chromatograms of counterfeits were less than 0.042 and the characteristic peaks were not observed on the HPLC chromatograms of these counterfeit samples. It indicated the true or false Tianma can be identified by either the similarity or characteristic peaks on HPLC fingerprint. Comparing the Winter Tianma with Spring Tianma showed that the HPLC chromatograms of 15 winter Tianma samples and 11 spring Tianma samples were similar at the mean correlation coefficient of 0.908. But the intensity of the characteristic peaks were different between the two groups of Tianma samples, i.e. the intensity of gastrodin, paishin A and C in winter Tianma was lower than those in spring Tianma. The Winter Tianma and Spring Tianma could be discriminated by either the Fisher unstandardized discrimination function or Linear discriminant function, based on the peak areas of 11 common peaks on HPLC chromatograms as variate.

ABSTRACT

Objective To observe the effect of nicorandil on slow-flow phenomenon in percutaneous coronary intervention (PCI) in patients with acute non-ST segment elevated myocardial infarction (NSTEMI). Methods A total of 159 NSTEMI patients were enrolled. Based on the TIMI flow of target lesion blood vessels after PCI, patients were divided into two groups. There were 31 cases in no flow/slow flow group (TIMI≤2), and 128 cases in normal group (TIMI=3). The general clinical data, immediate TIMI flow grade of infarct-related artery (IRA) after PCI treatment, post-operative corrected TIMI frame count (CTFC), TIMI myocardial perfusion grade (TMPG), thrombolysis in myocardial infarction signs of a blood clot, number of diseased vessels and major adverse cardiac events were compared between the two groups. The patients in no flow/slow flow group were given nicorandil, and changes of blood flow before and after treatment were observed. The influence factors of no flow/slow flow were analyzed by multifactor Logistic regression. Results The proportions of patients with history of smoking, the proportion of patients with diabetes history, the proportion of patients with hyperlipidemia, the proportion of patients with low blood pressure in operation, and the number of implanted stents, the proportions of patients took tirofiban in operation, post-operative CTFC, the proportions of patients with thrombosis signs were significantly higher in no flow/slow flow group than those in the normal group (P<0.05). There were no significant differences in heart rates in operation, IRA distribution and the number of lesion vessels between the two groups. There were also no significant differences in the incidence of MACE and left ventricular ejection fraction between the two groups. After the application of nicorandil, the proportion of patients with TIMI blood flow 3 and proportions of cTFC and TMPG were significantly higher than before treatment (P<0.05). Results showed that smoking history, history of diabetes, multiple stents (more than 3), hypotension in PCI, and signs of blood clot were factors influencing the slow flow of coronary arteries. Conclusion Nicorandil can significantly improve the no flow/slow flow in PCI in patients with NSTEMI.

AIM:To investigate whether rebamipide repairs the small intestinal epithelial barrier in aspirin-induced small intestinal injury (SII) in mice and its mechanism.METHODS:Small intestinal injury was induced by aspirin (200 mg · kg-1 · d-1 for 5 d) in BALB/c mice.Based on the treatment with aspirin and/or rebamipide (320 mg ·kg-1 · d-1),the mice were divided into 4 groups (n =18 in each group).The living mice in each group (n =6) were sacrificed via cervical dislocation method at day 0,day 5,and day 10.The structure and function of intestinal barrier and the levels of the signaling pathway factors were measured by transmission electron microscopy,immunohistochemistry,qPCR,and Western blot.RESULTS:Tight junctions between intestinal epithelial cells improved significantly after rebamipide treatment.The expression of ZO-1 and occludin in the injured small intestine showed a gradually increasing trend after rebamipide administration (P < 0.05).There was a decreased trend of D-lactate level in rebamipide-treated SII mice (P < 0.05).The expression of cyolooxygenase-2 (COX-2),β-catenin,and c-Myc,and prostaglandin E2 concentration in small intestinal tissues were significantly increased in rebamipide treatment group (P < 0.05).However,down-regulated COX-1 expression in the SII mice was sustained at a low level after rebamipide administration.CONCLUSION:Rebamipide repairs the injury of small intestinal mucosa and improves the structure and function of small intestinal barrier in aspirininduced SII mice by up-regulating the expression of COX-2.

ABSTRACT

Objective To identify clinical and dosimetric parameters from dose-volume histogram(DVH) relating with incidence of severe acute radiation-induced esophagitis(RE)in patients with non-small cell lung can-cer(NSCLC)underwent tomotherapy with concurrent or sequential chemotherapy. Methods Records about clini-cal information and treatment plan parameters from DVH of 62 NSCLC patients treated with tomotherapy were pro-spectively collected to assess the correlation to severe acute RE from January 2012 to December 2016. Results There were 24.2%patients developed grade 3 RE,grade 4 or 5 in 0%patients. Multivariate analysis indicated that concurrent chemotherapy,esophagus median dose and esophagus V25 and V55 were the influencing factors of RE. The incidence of low frequencies RE was correlated with sequential chemotherapy ,esophagus median dose < 49 Gy,esophagus V25 < 64% ,V55 < 33% and V60 < 15%. Conclusions For NSCLC patients treated with tomo-therapy and chemotherapy,the occurrence of acute RE was similar to that of other techniques. It is recommended to balance such parameters for optimizing treatment planning.

ABSTRACT

Objective To systematically evaluate the effectiveness and safety of Elemene combined with radiotherapy for intervention in brain metastasis from pulmonary neoplasms. Methods Articles of clinical randomized controlled trials about Elemene combined with radiotherapy for intervention in brain metastasis from pulmonary neoplasms from the establishment of the databases to October of 2016 from CNKI, CBM, Chongqing Weipu, Wanfang database, Cochrane Library, PubMed and Embase were retrieved by computers. Bias risk assessment tools in Cochrane systematic evaluation handbook 5.1.0 was used to conduct quality evaluation for included articles. RevMan5.3 software was used to carry out Meta-analysis. Results Totally 12 articles and 839 patients were included. Results of Meta-analysis showed that Elemene combined with radiotherapy had more obvious curative effect on narrowing the neoplasm compared with pure radiotherapy [OR=2.73, 95%CI (1.97, 3.77), P<0.000 01], and improve patients' life quality at the same time [OR=3.85, 95%CI (2.23, 6.65), P<0.000 01], and relieve adverse reactions [OR=4.16, 95%CI (2.40, 7.22), P<0.000 01]. Conclusion Elemene combined with radiotherapy for intervention in brain metastasis from pulmonary neoplasms shows confirmed efficacy, and is relatively safe. But whether the program should be widely used in clinic, more large sample, multi-center, and high-quality clinical randomized controlled trials are still needed.
