ABSTRACT

ObjectiveTo systematically collect, analyze, and evaluate the randomized controlled trials (RCT) of Chinese patent medicine combined with western medicine in the treatment of hypertension, map the evidence, and provide reference for the future clinical research and formulation of guidelines and policies. MethodThe relevant articles were retrieved from China Biology Medicine disc, China National Knowledge Infrastructure (CNKI), VIP, Wanfang Data, PubMed, Embase, and Cochrane Library with the time interval from inception to December 31, 2022. The RCT of Chinese patent medicines combined with western medicine in the treatment of hypertension were included. The research characteristics and methodological quality were analyzed and evaluated. ResultA total of 330 RCTs of treating hypertension with Chinese patent medicines combined with Western medicine were included in this study, all of which were published in Chinese. These RCTs involved 88 Chinese patent medicines and 37 788 patients, and 46% of RCT had the sample size ≥100 patients. Eighty-seven percent of RCT showed the study period within 3 months. All the interventions in the RCTs were Chinese patent medicine + western medicine vs western medicine. Among the evaluation indicators, blood pressure, response rate, TCM syndrome score, endothelial cell function, and safety were mainly concerned. In terms of methodological quality, most articles did not mention the generation of random sequences, allocation concealment, or blinding method. The blinding evaluation of outcomes showed low risks of bias, and there was insufficient information to judge whether there was selective bias or other bias. ConclusionThere were many Chinese patent medicines used in combination with western medicine in the treatment of hypertension, and they were mainly taken orally. The existing RCT had problems such as small sample size, unclear clinical value positioning, imperfect design failing to reflect the value of Chinese patent medicines, unreasonable measurement indicators, and non-standard measurement methods. Future research should solve the above problems, improve the research quality, value, and authenticity, and enhance the reliability and extension of evidence.

ABSTRACT

ObjectiveTo evaluate the quality of research and evidence related to antihypertensive Chinese patent medicines combined with western medicines for the treatment of hypertension, synthesize and update the evidence, form expert consensus, and provide evidence for clinical decision-making. MethodThe databases of China National Knowledge Infrastructure (CNKI), WanFang Data Knowledge Service Platform (WanFang), Vip Chinese Science and Technology Journal Database (VIP), Chinese Biomedical Literature Service System (Sinomed), National Library of Medicine (PubMed), Cochrane Library, Web of Science, and US Clinical Trials Registry were searched for randomized controlled trials of antihypertensive Chinese medicine combined with western medicine for the treatment of hypertension from database construction to July 31, 2022. The quality of the literature was evaluated using the bias risk assessment tool in Cochrane Handbook 6.3. Evidence synthesis of main outcome indicators was performed using R software. The Grading of Recommendations Assessment, Development, and Evaluation profiler (GRADEprofiler) 3.6 was employed to evaluate the quality of evidence. Expert consensus was formed based on the Delphi method after two rounds of voting. Result64 pieces of literature were included, and the results of literature quality evaluation and risk of bias showed that 70.31% (45/64) of the studies indicated some risks, and 29.69% (19/64) indicated high risks. Compared with conventional western medicines, the combination of Chinese patent medicines with western medicines can significantly lower systolic pressure (SBP) and diastolic pressure (DBP), increase the effective rate of antihypertensive, reduce the incidence of adverse reactions, endothelin-1, and traditional Chinese medicine syndrome scores. Egger's test showed that Songling Xuemaikang capsules reduced SBP and DBP. Tianma Gouteng granules reduced SBP and DBP and increased the effective rate of antihypertensive, and Xinmaitong capsules reduced SBP and increased the effective rate of antihypertensive, without significant publication bias. Songling Xuemaikang capsules increased the effective rate of antihypertensive, and Xinmaitong capsules decreased DBP, with significant publication bias. The results of the GRADE evidence quality evaluation showed that most evidence was at grades B and C. Finally, four strong recommendations and 14 weak recommendations were formed. ConclusionCompared with conventional western medicines for the treatment of hypertension, antihypertensive Chinese patent medicines combined with western medicines have advantages in reducing blood pressure and improving drug use safety, but they are mostly weak recommendations in terms of efficacy, and more high-quality evidence is needed.

ABSTRACT

ObjectiveTo evaluate the effect of antihypertensive and lipid-regulating Chinese patent medicine combined with conventional Western medicine in the treatment of hypertension with dyslipidemia. To carry out the evidence synthesis of clinical research and provide evidence-based evidence support for clinical decision-making. MethodThe databases including China National Knowledge Infrastructure (CNKI),Wanfang Data Knowledge Service Platform (WF),VIP,SinoMed,Embase,PubMed,Web of Science (WOS),and the Cochrane Library were searched for randomized controlled trials (RCT) of all listed Chinese patent medicines in the treatment of hypertension with dyslipidemia from the establishment of the databases to April 15,2023. The literature was screened and extracted,and the risk of bias tool 2.0 (RoB2) was used to assess the quality and risk of bias of the methodology. Revman 5.4.1 software was used to analyze the outcome indicators. Grading of Recommendations Assessment,Development and Evaluation (GRADE) was applied to assess the quality of evidence formed by clinical research data. The inclusion and recommendation of Chinese patent medicines in the National Drug Catalogue for Basic Medical Insurance,Work-related Injury Insurance and Maternity Insurance (2022) and domestic guidelines and consensus were searched to form a bubble chart. ResultA total of 15 studies were included. The evaluation of the methodological quality of each study showed that the risk of bias stemmed from the lack of blinding and allocation concealment,and low sample size. The comprehensive analysis of clinical studies showed that Dengzhan Shengmai capsules combined with rosuvastatin and amlodipine besylate,Yindan Xinnaotong capsules combined with simvastatin and levamlodipine tablets,Xiaoshuan Tongluo capsules combined with nifedipine controlled release tablets and pravastatin sodium tablets,Xinshubao capsules combined with atorvastatin calcium tablets and irbesartan,Wenyading capsules combined with enalapril,and Jiangzhining tablets combined with conventional Western medicines were all superior to conventional Western medicines used in the control group in improving systolic blood pressure (SBP),diastolic blood pressure (DBP),cholesterol (TC),triglyceride (TG),low density lipoprotein cholesterol (LDL-C),and high density lipoprotein cholesterol (HDL-C). There was no significant difference in the incidence of adverse reactions between the two groups. The GRADE evaluation of the main outcome indicators showed that the evidence quality of SBP and incidence of adverse reactions was graded as B,that of DBP as C,and that of total TC,TG,LDL-C,and HDL-C as D. The evaluation of Chinese patent medicines covered by medical insurance and recommended by guidelines and consensus showed that Yindan Xinnaotong soft capsules,Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules belonged to class B drugs of medical insurance,and were recommended for 7,6 and 3 times in the guidelines and consensus,respectively. ConclusionCompared with simple medicine treatment,Chinese patent medicine combined with conventional Western medicine has more advantages in improving blood pressure and blood lipid,and shows higher safety. Among them,Yindan Xinnaotong soft capsules,Dengzhan Shengmai capsules and Xiaoshuan Tongluo capsules have stronger clinical applicability and economy. All the trials included in this article adhered to the principle of randomization and reported the outcome measures. However,the quality of evidence in related clinical studies was low. In terms of trial design,large-sample,multi-center,blinded randomized controlled trials based on the consolidated standards of reporting trials (CONSORT) statement are still needed for comprehensive trial designs and reporting,to further improve the GRADE quality evaluation and guideline formulation under the guidance of evidence-based medicine,so as to provide higher quality evidence-based research evidence for clinical decision-making.

ABSTRACT

Peptides from Pilose antler aqueous extract (PAAE) have been shown to stimulate the proliferation and differentiation of bone marrow mesenchymal stem cells (BMSCs). However, the underlying molecular mechanisms are not well understood. Here, PAAE was isolated and purified to explore the molecular mechanisms underlying PAAE's effects on BMSCs as well as its osteoprotective effects in ovariectomized rats. Our results showed that PAAE promoted proliferation and differentiation of BMSCs to become osteoblasts by enhancing ALP activity and increasing extracellular matrix mineralization. The trabecular microarchitecture of ovariectomized rats was also found to be protected by PAAE. Quantitative reverse transcription-polymerase chain reaction (Quantitative RT-PCR) results suggest that PAAE also increased the expression of osteogenic markers including, alkaline phosphatase (ALP), runt-related transcription factor 2 (Runx2), osteocalcin (OCN), bone morphogenetic protein-2 (BMP-2), and collagen I (COL-I). Immunoblotting results indicated that PAAE upregulated the levels of BMP-2 and Runx2 and was associated with Smad1/5 phosphorylation. PAAE A at the concentration of 200 μg·mL showed the strongest effect on proliferation and osteogenic differentiation of BMSCs after 48 h. Using matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS), we identified the molecular weight of PAAE A and found that it is less than 3000 Da and showed several significant peaks. In conclusion, PAAE activates the BMP-2/Smad1, 5/Runx2 pathway to induce osteoblastic differentiation and mineralization in BMSCs and can inhibit OVX-induced bone loss. These mechanisms are likely responsible for its therapeutic effect on postmenopausal osteoporosis.

ABSTRACT

<p><b>OBJECTIVE</b>Low-intensity pulsed ultrasound (LIPUS) has been reported to enhance proliferation and to alter protein production in various kinds of cells. In the present study, we measured the neurites length after LIPUS treatment to define the effectiveness of LIPUS stimulation on neurons, and then we examined the acticity of GSK-3beta to study the intracellular mechanism of neurite's outgrowth.</p><p><b>METHODS</b>LIPUS was applied to cultured primary rat cortical neurons for 5 minutes every day with spatial- and temporal average intensities (SATA) of 10 mW/cm(2), a pulse width of 200 microseconds, a repetition rate of 1.5 KHz, and an operation frequency of 1 MHz. Neurons were photographed on the third day after LIPUS treatment and harvested at third, seventh, and tenth days for immunoblot and semi-quantitative RT-PCR analysis.</p><p><b>RESULTS</b>Morphology change showed that neurite extension was enhanced by LIPUS. There was also a remarkable decrease of proteins, including p-Akt, p-GSK-3beta, and p-CRMP-2, observed on the seventh and tenth days, and of GSK-3beta mRNA expression, observed on the seventh day, in neurons treated with LIPUS.</p><p><b>CONCLUSION</b>LIPUS can enhance elongation of neurites and it is possible through the decreased expression of GSK-3beta.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the influences of Mycobacterium tuberculosis on the levels of human acute monocytic leukemia cell line THP-1 apoptosis and death.</p><p><b>METHODS</b>Human acute monocytic leukemia cell line THP-1 were infected with Mycobacterium tuberculosis strains H37Ra, H37Rv, or Beijing genotype (BJTB), respectively, to construct the infection models. Cell apoptosis was detected using flow cytometry. The distribution of the apoptotic proteins was detected using immunofluorescent staining assays. The cells late apoptosis was detected using terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling staining assays. The change of cell death was determined by Tyrpan blue staining assays.</p><p><b>RESULTS</b>THP-1 apoptosis was induced by Mycobacterium tuberculosis strains H37Ra, H37Rv, and BJTB. H37Ra strongly induced THP-1 apoptosis, H37Rv weakly induced THP-1 apoptosis, and BJTB induced THP-1 apoptosis at the lowest level among these three Mycobacterium tuberculosis strains. On the contrary, BJTB strongly induced THP-1 death, H37Rv weakly induced THP-1 death, and H37Ra induced THP-1 death at the lowest level.</p><p><b>CONCLUSIONS</b>Mycobacterial strains with different virulence induce different levels of apoptosis and death of THP-1 cells. Compared with highly virulent strains, attenuated strains induce more apoptosis and less death.</p>
