Application and reflection on pilot study in acupuncture clinical research / 中国针灸

Pilot study is essential prerequisite for large-scale research. Acupuncture is a complex intervention measure. The factors of its clinical effect and effect mechanism are complicated. Hence, the resource waste is easily induced in research if the large-scale clinical research is rashly carried out before scientific verification. Currently, there is still a lack of high-quality evidence of clinical research, which affects the promotion and application of the curative effect of acupuncture. The pilot study of acupuncture can evaluate the feasibility and the process coordination of trial, optimize program and process and provide the basis of sample size calculation prior to launching a full-scale trial. Thereby, the methodological quality of acupuncture research and the reliability of trial results can be improved. In the paper, the arguments focus on the definition, design and report of pilot study so as to provide the approaches and references for the design and implementation of pilot study of clinical research of acupuncture.

Effects of SGLT2i on 24-hour ambulatory blood pressure in patients with type 2 diabetes complicating hypertension: a meta-analysis / 中华心血管病杂志

Objective: To analyze the effects of different types of sodium-glucose cotransporter 2 inhibitors (SGLT2i) on 24-hour ambulatory blood pressure in patients with type 2 diabetes mellitus and hypertension. Method: In this meta-analysis, we searched for randomized controlled trials on the effect of SGLT2i on 24-hour ambulatory blood pressure in patients with type 2 diabetes and hypertension. Three databases, namely PubMed, Web of Science and Cochrane Library, were searched. The search was organized on the concept of 3 conceptual groups: the first group contained terms used to describe SGLT2i, the second group contained terms related to blood pressure, and the third group contained terms used to describe randomized controlled trials. The search time was from the establishment of the database to December 2020. The inclusion and exclusion criteria were formulated in accordance with the requirements of the Cochrane systematic review. According to whether the heterogeneity of the study was significant or not, a random effect model or a fixed effect model were used to conduct the analysis on the impact of different types of SGLT2i on 24-hour ambulatory blood pressure and day and night blood pressure in patients with type 2 diabetes and hypertension. Further subgroup analysis was performed to define potential factors, which might lead to clinical heterogeneity. Results: Seven clinical trials were finally included. The result of the meta-analysis showed that compared with placebo group, SGLT2i could reduce the 24-hour dynamic systolic blood pressure of patients with type 2 diabetes and hypertension by 4.36 mmHg (1 mmHg=0.133 kPa). Reduction was 4.59, 3.74, 5.06, and 3.64 mmHg by canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin respectively; SGLT2i could reduce the 24-hour dynamic diastolic blood pressure of patients with type 2 diabetes and hypertension by 2.20 mmHg, and the reduction was 2.30, 1.22, 2.00, and 2.69 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin respectively. SGLT2i could reduce the daytime systolic blood pressure of patients with type 2 diabetes and hypertension by 5.25 mmHg, and reduction was 5.38, 4.87, 6.00, and 4.37 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin, respectively. Simultaneously, SGLT2i could reduce the diastolic blood pressure of patients with type 2 diabetes and hypertension by 2.62 mmHg, and the reduction was 2.56, 2.47, and 2.80 mmHg by canagliflozin, empagliflozin and ertugliflozin, respectively. SGLT2i could reduce the nighttime systolic blood pressure of patients with type 2 diabetes and hypertension by 3.62 mmHg, and the reduction was 2.09, 2.06, 3.92, and 2.45 mmHg by canagliflozin, dapagliflozin, empagliflozin and ertugliflozin, respectively. At the same time, SGLT2i could reduce the nighttime diastolic blood pressure of patients with type 2 diabetes and hypertension by 1.60 and 1.51 mmHg, the reduction was 1.53 and 2.58 mmHg by canagliflozin, empagliflozin and ertugliflozin, respectively. Conclusion: SGLT2i can reduce 24-hour ambulatory blood pressure in patients with type 2 diabetes and hypertension.

Study on tanshinones regulating root-associated microbiomes of Salvia miltiorrhiza / 中国中药杂志

The plant root-associated microbiomes include root microbiome and rhizosphere microbiome, which are closely related to plant life activities. Nearly 30% of photosynthesis products of plants are used to synthesize root compounds, there is evidence that root compounds regulate and significantly affect the root microbiome Tanshinones are the main hydrophobic components in Salvia miltiorrhiza. In order to study whether these compounds can regulate the root-associated microbiomes of S. miltiorrhiza, our study first identified a white root S. miltiorrhiza(BG) which contains little tanshinones. Retain of the fifth intron of tanshinones synthesis key enzyme gene SmCPS1 leading to the early termination of the SmCPS1 gene, and a stable white root phenotype. Further, wild type(WT) and BG were planted in greenhouse with nutrient soil(Pindstrup, Denmark) and Shandong soil(collected from the S. miltiorrhiza base in Weifang, Shandong), then high-throughput sequencing was used to analyze the root-associated microbiomes. The results showed that the tanshinones significantly affected the root-associated microbiomes of S. miltiorrhiza, and the impact on root microbiomes was more significant. There are significant differences between WT and BG root microbiomes in species richness, dominant strains and co-occurrence network. Tanshinones have a certain repelling effect on Bacilli which belongs to Gram-positive, while specifically attract some Gram-negative bacteria such as Betaproteobacteria and some specific genus of Alphaproteobacteria. This study determined the important role of tanshinones in regulating the structure of root-associated microbiomes from multiple angles, and shed a light for further improving the quality and yield of S. miltiorrhiza through microenvironment regulation.

Effects of Ultrashort Wave on Inflammatory of Acute Lung Injury and Related Signaling Pathway in Rats / 中国康复理论与实践

Objective:To observe the effects of ultrashort wave (USW) on lipopolysaccharide (LPS) induced acute lung injury (ALI) and nucleotide-binding oligomerization domain like receptor protein 3 (NLRP3) signaling pathway in rats. Methods:Twenty-four three-month-old male Sprague-Dawley rats were randomly divided into control group (n = 8), ALI group (n = 8) and USW group (n = 8). The ALI and USW groups were instilled with LPS to induce ALI, and the USW group was treated with ultrashort wave 0, four and eight hours after instillation, 15 minutes a time. Twenty-four hours after instillation, the lung tissue of the rats was measured the wet/dry mass ratio (W/D), and observed under HE staining. Serum levels of interleukin (IL)-1β and IL-18 were detected with ELISA. The mRNA and protein expression of NLRP3, caspase-1 and IL-1β in the lung tissue were detected with reverse transcription polymerase chain reaction and Western blotting, respectively. Results:W/D increased in ALI group compared with that of the control group (P < 0.05), and it decreased in USW group without significance compared with that of ALI group (P > 0.05). Lung injury score increased in ALI group compared with that of the control group (P < 0.05), and it decreased in USW group compared with that of ALI group (P < 0.05); as well as the serum IL-1β and IL-18, and mRNA and protein expression of NLRP3, caspase-1 and IL-1β. Conclusion:USW can alleviate the inflammatory of acute lung injury, which may associate with inhibiting of NLRP3 signaling pathway.

Objective To observe the effects of hyperbaric oxygen in the treatment of the rats with optic nerve crush. Methods In this study, 24 rats with traumatic optic nerve injury were recruited. The rats'left eyes were injured in the optic nerve and the right eyes as the controls were applied with sham-operation. The rats were divided into the treatment group and the control group in accordance with the random number table. The experimental group was treated with two-course hyperbaric oxygen one hour a day, 10 days a course. The control group breathed fresh air under standard atmospheric pressure. F-VEP was detected on day 3, 10, 20 during the experiment. Results In the control group, latency of F-VEP delayed (P＜0.05) and the amplitude of P100 decreased (P＜0.05) in the injured eye compared to the normal eye. In the experimental group, no obvious difference was found in the latency of F-VEP and the amplitude of P100 in the injured eye compared to the normal eye (P＞ 0.05) . The comparison of F-VEP data of the injured eyes showed that incubation period was in advance (P＜ 0.05) and amplitude increased (P＜0.05) in the experimental group. The comparison of F-VEP data tested at different time points was statistical significant. Conclusion The rat model of optic nerve injury was successful. Hyperbaric oxygen therapy showed no interference with the F-VEP data of the injured eye by causing no damage to the normal eye and was proved effective. Longer treatment provided better results.

Effects of CO2 pretreatment on the volatile compounds of dried Chinese jujube (Zizyphus jujuba Miller)

Abstract The aim of this study was to investigate whether anaerobic metabolites could induce volatile compounds and improve aroma of dried jujube (Ziziphus jujuba Miller). Jujube fruits were incubated in a polyvinyl chloride bag containing 5% CO2 and 95% N2 for up to 168 h at 25 °C and 3 samples were randomly removed every 6 h and oven dried to a moisture content of ≅ 20%. The volatile compounds of control and 5% CO2-pretreated Chinese jujube fruits were extracted by simultaneous distillation extraction and identified by gas chromatography-mass spectrometry(GC-MS). The acetaldehyde and ethanol contents were determined by gas chromatography (GC). The results indicated that a large accumulation of acetaldehyde and ethanol caused changes in aroma composition of dried jujube products and 5% CO2 pretreatment led to an increase in the levels of some compounds, particularly esters, acetaldehydes, and ethanol, whereas the amount of acids were decreased significantly. Principal component analysis showed that integrative scores of 5% CO2 pretreatment at 120 h were the highest, and aroma quality was better than that of the control. Relatively low concentrations of anaerobic respiration metabolites are good for jujube fruit aroma composition.

Impact of parameter fluctuations on the performance of ethanol precipitation in production of Re Du Ning Injections, based on HPLC fingerprints and principal component analysis / 中国天然药物

The present study was designed to determine the relationships between the performance of ethanol precipitation and seven process parameters in the ethanol precipitation process of Re Du Ning Injections, including concentrate density, concentrate temperature, ethanol content, flow rate and stir rate in the addition of ethanol, precipitation time, and precipitation temperature. Under the experimental and simulated production conditions, a series of precipitated resultants were prepared by changing these variables one by one, and then examined by HPLC fingerprint analyses. Different from the traditional evaluation model based on single or a few constituents, the fingerprint data of every parameter fluctuation test was processed with Principal Component Analysis (PCA) to comprehensively assess the performance of ethanol precipitation. Our results showed that concentrate density, ethanol content, and precipitation time were the most important parameters that influence the recovery of active compounds in precipitation resultants. The present study would provide some reference for pharmaceutical scientists engaged in research on pharmaceutical process optimization and help pharmaceutical enterprises adapt a scientific and reasonable cost-effective approach to ensure the batch-to-batch quality consistency of the final products.
