ABSTRACT

OBJECTIVE@#To identify the key genes and explore mechanisms in the development of myelodysplastic syndrome (MDS) by bioinformatics analysis.@*METHODS@#Two cohorts profile datasets of MDS were downloaded from Gene Expression Omnibus (GEO) database. Differentially expressed gene (DEG) was screened by GEO2R, functional annotation of DEG was gained from GO database, gene ontology (GO) enrichment analysis was performed via Kyoto Encyclopedia of Genes and Genomes (KEGG) database, and key genes were screened by Matthews correlation coefficient (MCC) based on STRING database.@*RESULTS@#There were 112 DEGs identified, including 85 up-regulated genes and 27 down-regulated genes. GO enrichment analysis showed that biological processes were mainly enriched in immune response, etc, cellular component in cell membrane, etc, and molecular function in protein binding, etc. KEGG signaling pathway analysis showed that main gene enrichment pathways were primary immunodeficiency, hematopoietic cell lineage, B cell receptor signaling pathway, Hippo signaling pathway, and asthma. Three significant modules were screened by Cytoscape software MCODE plug-in, while 10 key node genes (CD19, CD79A, CD79B, EBF1, VPREB1, IRF4, BLNK, RAG1, POU2AF1, IRF8) in protein-protein interaction (PPI) network were screened based on STRING database.@*CONCLUSION@#These screened key genes and signaling pathways are helpful to better understand molecular mechanism of MDS, and provide theoretical basis for clinical targeted therapy.

ABSTRACT

Heat-sensitive moxibustion is the appropriate technique of the external treatment in traditional Chinese medicine and it is widely used in community because of its "easy learning, simple operation and clear curative effect". Pragmatic randomized controlled trial is a main intervention design in the real world study, which provides a high-level evidence for the effectiveness assessment of heat-sensitive moxibustion in community management. Focusing on the key links of randomization, e.g. block randomization, stratified randomization, cluster randomization, sample size allocation, allocation concealment and blinding, the paper elaborates the advantages, disadvantages and technical details of two-stage randomization with consideration of patient preference in pragmatic randomized controlled trials of heat-sensitive moxibustion in community. It facilitates improving the quality of evidence, reproducibility and methodological homogeneity among different trials.

ABSTRACT

OBJECTIVE@#To provide evidence on the efficacy and safety of Chinese herbal medicine (CHM) as interventions for systemic lupus erythematosus (SLE).@*METHODS@#Seven electronic databases, including the Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), Chinese Biomedical Literature Service System (SinoMed), Wanfang, Embase, and PubMed, were comprehensively searched, from their inception to August 16, 2020, for all randomized controlled trials (RCTs) that focused on CHM used alone or in combination with conventional medicine for SLE. Outcomes were SLE activity index (SLEDAI), traditional Chinese medicine symptom/syndrome score (TCMSS), dosage of glucocorticoids, main serological testing, and incidence of adverse events. Data were extracted and pooled using Review Manager 5.3 software.@*RESULTS@#A total of 13 RCTs enrolling 856 participants met our inclusion criteria. Meta-analyses showed that, compared to placebo, CHM had statistically significant effect on reducing SLEDAI score (MD=-1.74, 95% CI: -2.29 to -1.18), diminishing TCMSS (SMD=-0.89, 95% CI: -1.16 to -0.62), decreasing dosage of glucocorticoids (MD=-2.41 mg/d, 95% CI: -3.34 to -1.48), lowering erythrocyte sedimentation rate (MD=-4.78 mm/h, 95% CI: -8.86 to -0.71), and increasing serum complement C4 level (MD=0.03 mg/dL, 95% CI: 0.00 to 0.06). No significant difference was found between CHM and placebo on adverse events.@*CONCLUSIONS@#CHM provided significant beneficial effect on controlling disease activity and reducing dose of glucocorticoids used among SLE patients. Future advanced designed RCTs for CHM treating moderate to severe SLE with multicenter and longer follow-up are urgently needed.

ABSTRACT

In 2013,China pharmaceutical regulatory department issued guiduance on postmarketing drug safety monitoring for industry. It aimed to encourage industry to carry out postmarketing drug safety monitoring including hospital-based intensive monitoring of postmarketing Chinese patent medicine. Subsequently,more and more such kind of studies have been performed all over China. However,in view of the current situation in this field,the development of hospital-based intensive monitoring of postmarketing Chinese patent medicine lacks standardization,such as unreasonable design,omission of reports about adverse drug reactions,inadequate process of quality control,non-standardized interpretation of adverse reactions,etc. Therefore,it is necessary to formulate relevant technical specifications to guide this area. The developing of this technical specification refered to the international post-marketing safety monitoring model and advanced design concepts and methods. We developed it under the guidance of relevant laws,regulations and technical documents in China. Meanwhile the characteristics of Chinese patent medicines and the real situation in this area were considered. The aim of this technical specification is to obtain the incidence,type,degree and clinical manifestation of adverse drug reactions of Chinese patent medicines,to find new risk signals of adverse reactions,to identify risk factors,and to provide a basis for the formulation of risk management and control plans. This specification has been approved by China association of Chinese medicine which is numbered T/CACM011-2016.

ABSTRACT

Diemailing~® Kudiezi Injection( DKI) is widely used in the treatment of cerebral infarction,coronary heart disease and angina pectoris. Long-term clinical application and related research evidence showed that DKI has a good effect in improving the clinical symptoms of cardiovascular and cerebrovascular diseases. However,this injection has not been included in any clinical practice guideline. It has been found that the use of DKI is in wrong way in clinical practice in recent years. Therefore,clinical experts from the field of cardiovascular and cerebrovascular diseases nationwide are invited to compile this expert consensus in order to guide clinicians.GRADE system is used to grade the quality of evidence according to different outcomes according to degrading factors. Then it forms the recommendation or consensus suggestion through the nominal group method. The formation of expert consensus mainly considers six factors: quality of evidence,economy,efficacy,adverse reactions,patient acceptability and others. Based on these six aspects,if the evidence is sufficient,a " recommendation" supported by evidence is formed,and GRADE grid voting rule is adopted. If the evidence is insufficient,a " consensus suggestions" will be formed,using the majority voting rule. In this consensus,the clinical indications,efficacy,safety evidences and related preliminary data of DKI were systematically and comprehensively summarized in a concise and clear format,which could provide valuable reference for the clinical use of DKI. This consensus has been approved by China association of Chinese medicine which is numbered GS/CACM 202-2019.

ABSTRACT

PURPOSE: To assess the effectiveness and safety of acupuncture for erectile dysfunction (ED). MATERIALS AND METHODS: We searched six major English and Chinese databases included randomized controlled trials (RCTs) testing acupuncture alone or in combination for ED. Dichotomous data were presented as risk ratio (RR) and continuous data were presented as mean difference (MD) both with 95% confidence interval (CI). The Revman (v.5.3) was used for data analyses. Quality of evidence across studies was assessed by the online GRADEpro tool. RESULTS: We identified 22 RCTs, fourteen of them involving psychogenic ED. Most of the included RCTs had high or unclear risk of bias. There was no difference between electro-acupuncture and sham acupuncture with electrical stimulation on the rate of satisfaction and self-assessment (RR, 1.50; 95% CI, 0.71–3.16; 1 trial). Acupuncture combined with tadalafil appeared to have better effect on increasing cure rate (RR, 1.31; 95% CI, 1.00–1.71; 2 trials), and International Index of Erectile Function-5 scores (MD, 5.38; 95% CI, 4.46–6.29; 2 trials). When acupuncture plus herbal medicine compared with herbal medicine alone, the combination therapy showed significant better improvement in erectile function (RR, 1.68; 95% CI, 1.31–2.15; 7 trials). Only two trials reported facial red and dizziness cases, and needle sticking and pruritus cases in acupuncture group. CONCLUSIONS: Low quality evidence shows beneficial effect of acupuncture as adjunctive treatment for people mainly with psychogenic ED. Safety of acupuncture was insufficiently reported. The findings should be confirmed in large, rigorously designed and well-reported trials.

ABSTRACT

OBJECTIVE@#To investigate the use of antibiotics in children with community-acquired pneumonia (CAP) in multiple regions of China, and to provide a reference for CAP standard treatment and rational antibiotic use in children.@*METHODS@#The medical data of 1 383 children with CAP who were hospitalized in the department of pediatrics in 10 grade A tertiary hospitals from 9 cities between April 14, 2014 and January 1, 2016 were reviewed, to analyze the status of antibiotic use in hospitalized children in North China, Northeast China, East China, and South China.@*RESULTS@#The overall rate of antibiotic use in children with CAP was 89.08%, with 88.7% in North China, 95.5% in Northeast China, 83.3% in East China, and 86.6% in South China. The main types of antibiotics used were cephalosporins, macrolides, compound preparations of β-lactam antibiotics, polyphosphoric broad-spectrum antibiotics and other β-lactam antibiotics. The selection of antibiotics was generally rational, but antibiotics were still used in some patients with viral infection alone or a combined use of ≥2 kinds of antibiotics were noted in some patients with infection caused by one kind of pathogen. Irrational antibiotic use was observed in 131 children (10.63%).@*CONCLUSIONS@#There are high rates of antibiotic use and irrational use of antibiotics among children with CAP. Standard management of antibiotic use in children with CAP should be strengthened.

ABSTRACT

OBJECTIVE@#To assess the effect and safety of Huannao Yicong Formula (, HYF) in the treatment of patients with mild-to-moderate Alzheimer's disease (AD).@*METHODS@#Sixty patients with mild-tomoderate AD were evenly randomized into HYF group and donepezil group with the random number method. Patients in the HYF group took 5 g of HYF granules twice daily and 5 mg placebo of donepezil once daily. Patients in the donepezil group took 5 mg donepezil once daily and 5 g placebo of HYF granules twice daily. The intervention lasted for 6 months. Clinical researchers, participants and statisticians were blinded to the treatment assignment throughout the study. The primary outcomes were scores of Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog) and Chinese Medicine Symptom Scale (CM-SS). The secondary outcomes were scores of Montreal Cognitive Assessment (MoCA) test and Mini-Mental State Exam (MMSE). The serum levels of acetylcholinesterase (AchE) and amyloid-β protein 42 (Aβ) were detected with enzymelinked immunosorbent assay kits. The scale assessments were conducted at baseline, the 3rd and 6th months of treatment, respectively. Biochemistry tests were conducted at baseline and the 6th month of treatment.@*RESULTS@#A total of 52 patients completed the trial, 28 in HYF group and 24 in donepezil group. Compared with the baseline, HYF and donepezil signifificantly decreased the total scores of ADAS-Cog and CM-SS, and signifificantly increased the scores of MoCA and MMSE after 6-month treatment (all P<0.01). Both treatments remarkably reduced the serum levels of AchE and Aβ (both P<0.05). The CM-SS total effective rate of HYF was signifificantly higher than donepezil [75.00% (21/28) vs. 54.17% (13/24), P<0.05]. No severe adverse events were observed in both groups.@*CONCLUSION@#HYF is effective and safe for improving the cognitive function in mildto-moderate AD patients.

ABSTRACT

To provide the basis for the future research on the nephrotoxicity of Chinese herbal medicine through systematic and comprehensive summary of all the Chinese herbal medicines which may lead to nephrotoxicity. Foreign resources included PubMed and Cochrane library, and domestic research resources was China Food and Drug Administration(CDFA) Adverse Drug Reaction Monitoring Center database. The databases were searched from establishment to January 1, 2017. There was no limitation on research type. 28 English studies were found, including 97 Chinese herbs or prescriptions with the risk of nephrotoxicity. The following six Chinese herbal medicines with the risk of nephrotoxicity had a large number of studies: aristolochic acid(5 studies), Tripterygium wilfordii(4 studies), Erycibe obtusifolia(2 studies), Rheum palmatum(2 studies), Ephedra sinica(2 studies), and Atractylodes lances(2 studies). The remaining 91 Chinese medicines were reported with risk of nephrotoxicity in only 1 study respectively. CDFA reported 16 Chinese herbal medicines with the risk of nephrotoxicity, including Ganmaoqing Pian(capsule), Zhenju Jiangya Pian, T. wilfordii preparation, Vc-Yinqiao Pian, Chuanhuning injection, Shuanghuanglian injection, Qingkailing injection, Lianbizhi injection, herbal decoction containing Aristolochiae Radix, Guanxin Suhe Wan, Shugan Liqi Wan, Ershiwuwei Songshi Wan, herbal decoction containing Aristolochia Fangchi, herbal granules containing root of Kaempfer Dutchmanspipe, Ganmaotong(tablets), and Longdan Xiegan Wan. Currently, in addition to aristolochic acids, the most reported Chinese herbal medicine with the risk of nephrotoxicity is T. wilfordii preparation.

ABSTRACT

To evaluate the quality of randomized controlled trials(RCT) on nephrotoxicity of Tripterygium wilfordii preparations according to the CONSORT HARMs statement. The report quality of each included study was evaluated according to the CONSORT HARMs statement, and the number of entries that comply with CONSORT HARMs statement was calculated in each study to evaluate the report quality on nephrotoxicity-related adverse reactions of T. wilfordii preparations and summarize the problems in domestic studies on nephrotoxicity-related adverse reactions. A total of 16 RCTs were included, with an average of 7 entries complying with CONSORT HARMs statement per study. The report of the nephrotoxic-associated RCT of T. wilfordii preparations was of poor quality and the most non-repeating entries included the following ones: using validated tools to report adverse effects, standards for coding of the adverse reactions, describing how and when to collect data on adverse reactions in Method, describing how adverse reactions are attributed to T. wilfordii, clearly stating who has reported the adverse reactions, describing the analysis method of adverse reactions, describing the method of collecting recurrent adverse reaction data, describing any subgroup analysis and exploratory analysis associated with the hazard. We suggest that the studies on adverse reactions of traditional Chinese medicine should strictly report the entries according to the CONSORT HARMs statement, and take the characteristics of traditional Chinese medicine into account to report the details of the Chinese medicine like compositions, dose, taking time, combined medication and the dialectical typology of research objects.

ABSTRACT

To investigate the feasibility of applying the evidence-based rapid review in studying the nephrotoxicity of Tripterygium wilfordii preparation. We used four methods in relevant studies on the nephrotoxicity of T. wilfordii preparation. The first method had no limitation on any search terms, which was a traditional approach to retrieve systematic reviews. The second method limited the relevant search terms of T. wilfordii preparation to "all of CHMs containing T. wilfordii preparation approved by CFDA". The third method was to limit the relevant retrieval terms of nephrotoxicity as the "most frequently reported terms related to nephrotoxicity found in the study literature screening process in the early stage of systematic review". The fourth method was to limit the search terms relating to both T. wilfordii preparation and nephrotoxicity. Finally, the results of the last three search methods were compared with those of the first search method, and the feasibility of the rapid review method in the study for the nephrotoxicity of CHM was discussed. For the total number of literatures searched, the fourth method had the smallest number of literatures. For the number of articles in line with the inclusion criteria, the second method had the largest number of eligible literatures. For the type of literatures included, the forth method had a higher coincidence degree. The forth method was the best one, because it was not only consistent with the results, but also could minimize the workload. Rapid review is feasible in the study of nephrotoxicity of T. wilfordii.

ABSTRACT

Chinese patent medicine is widely used in clinical practice, but improper use will not only weaken the efficacy of drugs, but even cause adverse consequences. Evidence-based medicine provides guidance for clinical practice based on the best available evidence, experience of experts and needs of patients. However, considering the situation of "insufficient evidence" or "very low quality" in Chinese medicine research, experts consensus is the main basis for clinical decision-making, but expert opinions on which the consensus depends are susceptible to various subjective biases. Therefore, a reliable and scientific consensus-making process is needed to maximally avoid bias on consensus. Unlike the clinical practice guidelines, there is no unified formulating process for consensus in the world today. This article learns from a set of formulating processes from some international consensus formulating institutions/associations, combined with the characteristics and current situation of traditional Chinese medicine, and draws up a set of standard process that is suitable for the clinical experts consensus on Chinese patent medicine, with the expect of providing evidence and reference for consensus makers, and then bringing evidence-based assistance for the clinical standardized application of Chinese patent medicines.

ABSTRACT

The promulgation of standardized documents on traditional Chinese medicine has promoted the formulation of industrial standards of traditional Chinese medicine, including clinical practice guidelines and clinical expert consensus. In order to adapt to the current research situation of "insufficient evidence" or "very low quality" when developing clinical practice guideline in the field of traditional Chinese medicine, the author has made a retrospective study on the development of guidelines and consensus, and found that the consensus is more suitable for the current research status of Chinese patent medicine, as the stage of lack of high-quality clinical evidence will remain for a long time. However, unlike clinical practice guidelines, domestic scholars and consensus makers have insufficient understanding of the clinical experts consensus. This article will introduce the origin and status of the clinical experts consensus, the differences between clinical experts consensus and the clinical practice guidelines, and the basic principles that should be followed in the formulation of the clinical experts consensus of Chinese patent medicine, expecting to provide theory basis and reference for the normative formulation of clinical experts consensus.

ABSTRACT

Due to its own characteristics and research status, traditional Chinese medicine research often faces the reality of "insufficient evidence" or "very low quality" when making clinical practice guidelines. Therefore, in many cases, clinical decision-making of traditional Chinese medicine should rely mainly on expert consensus to achieve. A clear and detailed list of expert consensus report specifications will provide a good reporting tool for Chinese clinical expert consensus makers, which is very important for promoting the quality of consensus production and the promotion and application of consensus results. The author consulted the internationally published authoritative expert consensus, summarized the main points of the reports, combined with the formulation process of the clinical experts consensus of Chinese medicine, and the demonstration of clinical experts and methodologists, and then formulated the list of items for clinical expert consensus reports adapt to the field of Chinese medicine. This article introduces the entire list of items and elaborates on the key parts. It is expected to provide reference for the standardization of future clinical expert consensus reports.

ABSTRACT

Acupuncture clinical trials are designed to provide reliable evidence of clinical efficacy, and SCI papers is one of the high-quality clinical efficacy of acupuncture research. To analyze these papers published in high impact factor journals on acupuncture clinical trials, we can study clinical trials from design to implementation, the efficacy of prevention and cure, combined with international standard practices to evaluate the effectiveness and safety of acupuncture. That is the core of acupuncture clinical trials, as well as a prerequisite for outstanding academic output. A scientific and complete acupuncture clinical trial should be topically novel, designed innovative, logically clear, linguistically refining, and the most important point lies in a great discovery and solving the pragmatic problem. All of these are critical points of papers to be published in high impact factor journal, and directly affect international evaluation and promotion of acupuncture.

ABSTRACT

The aim of the present study was to investigate the effect of precursor brain-derived neurotrophic factor (proBDNF) on survival and neurite outgrowth of cultured rat spiral ganglion neurons (SGNs). Spiral ganglions (SG) were collected from postnatal day 5 Sprague Dawley (SD) rats, then enzymatically digested and suspended. Dissociated SGNs were plated on poly-D-lysine/laminin coated eight-well chamber plates and maintained at 37 °C for 4 h to promote the attachment of the neurons. Cultured SGNs were randomly divided into five groups: control group, BDNF group (BDNF 10 ng/mL), C10 group (proBDNF 10 ng/mL), C50 group (proBDNF 50 ng/mL), and C100 group (proBDNF 100 ng/mL). All groups were incubated in a serum-free medium. 48 h after incubation, SGNs were fixed and stained for βIII tubulin. Immunostaining of the cultured SGNs showed that, compared with the control group, the cellular survival of C50 group and C100 group were significantly reduced (P < 0.001). Furthermore, surviving numbers of the three proBDNF-treated groups were all lower than the BDNF group. In order to assess the effect of proBDNF on cell morphology, SGNs were divided into two categories: SGNs with or without neurites. The results demonstrated that proBDNF significantly increased the proportions of SGNs without neurites in C10, C50 and C100 groups compared with that in control group (P < 0.001). In addition, c-Jun N-terminal kinase (JNK) inhibitor, SP600125 (20 μmol/L) significantly increased the surviving number of SGNs in C50 group. These results suggest that proBDNF reduces the survival rate of cultured SGNs and inhibits the sprouting of neurites. Furthermore, the inhibition of JNK signaling attenuates the effect of proBDNF on SGNs survival.
