RESUMEN
Two Gram-stain-positive, aerobic, oxidase- and catalase-negative, non-motile, and short rod-shaped actinomycetes, named SYSU T00b441T and SYSU T00b490, were isolated from tidal flat sediment located in Guangdong province, PR China. The 16S rRNA gene sequence similarity, average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between SYSU T00b441T and SYSU T00b490 were 99.3, 99.5 and 97.1â%, respectively. Strains SYSU T00b441T and SYSU T00b490 exhibited the highest 16S rRNA gene sequence similarities to Actinotalea ferrariae CF 5-4T (97.1â%/98.2â%), with ANI values of 74.01/73.88â% and dDDH values of 20.5/20.4â%. In the phylogenomic tree, the two isolates were affiliated with the genus Actinotalea. The genomes of strains SYSU T00b441T and SYSU T00b490 were 3.31 and 3.34 Mb, and both had DNA G+C contents of 72.8âmol%, coding 3077 and 3085 CDSs, three and three rRNA genes, and 53 and 51 tRNAs, respectively. Growth occurred at 15-40â°C (optimum, 28-30â°C), pH 4.0-10.0 (optimum, 7.0) and in the presence of 0-7â% (w/v) NaCl (optimum, 3â%). The major fatty acids (>10ââ%) of strains SYSU T00b441T and SYSU T00b490 were anteiso-C15â:â0 and C16â:â0. The major respiratory quinone was identified as MK-10(H4). The polar lipids of strains SYSU T00b441T and SYSU T00b490 were diphosphatidyl glycerol, phosphatidylglycerol, phosphoglycolipid, phosphatidyl ethanolamine, two phosphatidylinositol mannosides, two glycolipids and two phospholipids. Based on these data, the two strains (SYSU T00b441T and SYSU T00b490) represent a novel species of the genus Actinotalea, for which the name Actinotalea lenta sp. nov is proposed. The type strain is SYSU T00b441T (=GDMCC 1.3827T=KCTC 49943T).

Two novel bacterial strains, designated as SYSU D00823T and SYSU D00873T, were isolated from sandy soil of the Gurbantunggut Desert in Xinjiang, north-west China. SYSU D00823T and SYSU D00873T shared 99.0â% 16S rRNA gene sequence identity, and were both most closely related to Pedobacter xinjiangensis 12157T with 96.1â% and 96.0â% similarities, respectively. Phylogenetic and phylogenomic analyses revealed that the two isolates and P. xinjiangensis 12157T formed a separate distinct cluster in a stable subclade with the nearby species Pedobacter mongoliensis 1-32T, as well as the genera Pararcticibacter and Arcticibacter. Furthermore, P. mongoliensis 1-32T formed a separate deep-branching lineage and did not form a cluster with members of the genus Pedobacter. The average nucleotide identity and digital DNA-DNA hybridization values between SYSU D00823T and SYSU D00873T and related species were well below the thresholds for species delineation (<81.0â% and <24.0â%, respectively). The genomes of SYSU D00823T and SYSU D00873T were 6.19 and 6.43 Mbp in size with 40.4â% and 40.5â% DNA G+C contents, respectively. The predominant fatty acids (>10â%) of SYSU D00823T and SYSU D00873T were iso-C15â:â0, iso-C17â:â0 3-OH and summed feature 3 (C16â:â1 ω7c and/or C16â:â1 ω6c). Menaquinone-7 was the only respiratory quinone. The major polar lipids were phosphatidylethanolamine, glycosphingolipid, aminoglycolipid/glycolipid, aminophospholipid and three or four unidentified polar lipids. These data indicated that strains SYSU D00823T and SYSU D00873T should be assigned to two novel species of a new genus within the family Sphingobacteriaceae, for which the names Desertivirga arenae gen. nov., sp. nov. and Desertivirga brevis sp. nov. are proposed. The type strains are SYSU D00823T (=CGMCC 1.18630T=MCCC 1K04973T=KCTC 82278T) and SYSU D00873T (=CGMCC 1.18629T=MCCC 1K04974T=KCTC 82281T), respectively. Accordingly, the reclassification of P. xinjiangensis as Desertivirga xinjiangensis comb. nov., and P. mongoliensis as Paradesertivirga mongoliensis gen. nov., comb. nov. are also proposed.

OBJECTIVE: To evaluate the effectiveness and safety of Chinese medicine (CM) in the treatment of coronavirus disease 2019 (COVID-19) in China. METHODS: A multi-center retrospective cohort study was carried out, with cumulative CM treatment period of ⩾3 days during hospitalization as exposure. Data came from consecutive inpatients from December 19, 2019 to May 16, 2020 in 4 medical centers in Wuhan, China. After data extraction, verification and cleaning, confounding factors were adjusted by inverse probability of treatment weighting (IPTW), and the Cox proportional hazards regression model was used for statistical analysis. RESULTS: A total of 2,272 COVID-19 patients were included. There were 1,684 patients in the CM group and 588 patients in the control group. Compared with the control group, the hazard ratio (HR) for the deterioration rate in the CM group was 0.52 [95% confidence interval (CI): 0.41 to 0.64, P<0.001]. The results were consistent across patients of varying severity at admission, and the robustness of the results were confirmed by 3 sensitivity analyses. In addition, the HR for all-cause mortality in the CM group was 0.29 (95% CI: 0.19 to 0.44, P<0.001). Regarding of safety, the proportion of patients with abnormal liver function or renal function in the CM group was smaller. CONCLUSION: This real-world study indicates that the combination of a full-course CM therapy on the basic conventional treatment, may safely reduce the deterioration rate and all-cause mortality of COVID-19 patients. This result can provide the new evidence to support the current treatment of COVID-19. Additional prospective clinical trial is needed to evaluate the efficacy and safety of specific CM interventions. (Registration No. ChiCTR2200062917).
RESUMEN
This study aims to systematically review the efficacy and safety of Shufeng Jiedu Capsules in the treatment of influenza. The randomized controlled trial(RCT) of Shufeng Jiedu Capsules alone or in combination with conventional western medicine for treating influenza were retrieved from PubMed, EMbase, Cochrane Library, Web of Science, SinoMed, CNKI, VIP, Wanfang, and ClinicalTrails.gov. The data analysis was performed in RevMan 5.4.1. The Cochrane risk of bias assessment tool was used to evaluate the quality of the involved RCT, and GRADEpro GDT to assess the quality of the evidence. A total of 11 RCTs involving 1 836 patients were included in this study. Compared with conventional western medicine, Shufeng Jiedu Capsules/Shufeng Jiedu Capsules + conventional western medicine improved the response rate(RR=1.09, 95%CI[1.03, 1.15], P=0.002), shortened the time to relief of cough, and increased the 3-day sore throat relief rate, whereas there was no significant difference in the time to fever abatement, the time to relief of sore throat, 3-day cough relief rate, or 3-day runny nose relief rate. Subgroup-analysis showed that Shufeng Jiedu Capsules + conventional western medicine improved the response rate(RR=1.11, 95%CI[1.08, 1.15], P<0.000 01), shortened the time to relief of cough, and increased the 3-day relief rate of symptoms(cough, sore throat, and runny nose) compared with conventional western medicine alone, while there was no significant difference in the time to fever abatement or the time to relief of sore throat. Shufeng Jiedu Capsules alone could not improve the response rate(RR=0.97, 95%CI[0.93, 1.02], P=0.19). In addition, Shufeng Jiedu Capsules/Shufeng Jiedu Capsules + conventional western medicine vs conventional western medicine were no significant difference in adverse reactions(RR=0.98, 95%CI[0.57, 1.69], P=0.95). The available evidence suggests that Shufeng Jiedu Capsules is effective and safe in the treatment of influenza, and the combination of Shufeng Jiedu Capsules with conventional western medicine can accelerate the relief of symptoms. However, since the number and quality of the included studies were low, the above findings remained to be further verified by multicenter RCT with large sample sizes.

Mining data from traditional Chinese medicine(TCM) prescriptions is one of the important methods for inheriting the experience of famous doctors and developing new drugs. However, current research work has problems such as to be optimized research plans and non-standard statistics. The main problems and corresponding solutions summarized by the research mainly include four aspects.(1)The research plan design needs to consider the efficacy and quality of individual cases.(2)The significance of the difference in confidence order of association rules needs to be further considered, and the lift should not be ignored.(3)The clustering analysis steps are complex. The selection of clustering variables should comprehensively consider factors such as the frequency of TCM, network topology parameters, and practical application significance. The selection of distance calculation and clustering methods should be improved based on the characteristics of TCM clinical data. Jaccard distance and its improvement plan should be given attention in the future. A single, unexplained clustering result should not be presented, but the final clustering plan should be selected based on a comprehensive consideration of TCM clinical characteristics and objective evaluation indicators for clustering.(4)When calculating correlation coefficients, algorithms that are only suitable for continuous variables should not be applied to binary variables. This article explained the connotations of the above problems based on the characteristics of TCM clinical research and statistical principles and proposed corresponding suggestions to provide important references for future data mining research work.

BACKGROUND: Thrombosis is a serious condition in children and neonates. However, the risk factors for thrombosis have not been conclusively determined. This study aimed to identify the risk factors for thrombosis in children and neonates in Intensive Care Unit (ICU) through a meta-analysis to better guide clinical treatment. METHODS: A systematic search of electronic databases (PubMed, Embase, Cochrane Library, WOS, CNKI, Wanfang, VIP) was conducted to retrieve studies from creation on 23 May 2022. Data on the year of publication, study design, country of origin, number of patients/controls, ethnicity, and type of thrombus were extracted. The publication bias and heterogeneity between studies were assessed, and pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed or random effects models. RESULTS: A total of 18 studies met the inclusion criteria. The incidence of thrombosis in children was 2% per year (95% CI 1%-2%, P < 0.01). Infection and sepsis (OR = 1.95, P < 0.01), CVC (OR = 3.66, [95%CL 1.78-7.51], P < 0.01), mechanical ventilation (OR = 2.1, [95%CL1.47-3.01], P < 0.01), surgery (OR = 2.25, [95%CL1.2-4.22], P < 0.01), respiratory distress (OR = 1.39, [95%CL0.42-4.63], P < 0.01), ethnicities (OR = 0.88, [95%CL 0.79-0.98], P = 0.78), gestational age (OR = 1.5, [95%CL1.34-1.68], P = 0.65)were identified as risk factors for thrombosis. CONCLUSIONS: This meta-analysis suggests that CVC, Surgery, mechanical ventilation, Infection/sepsis, gestational age, Respiratory distress, and different ethnicities are risk factors for thrombosis in children and neonates in ICU. These findings may help clinicians to identify high-risk patients and develop appropriate prevention strategies. TRIAL REGISTRATION: PROSPERO (CRD 42022333449).

In observational studies, herbal prescriptions are usually studied in the form of "similar prescriptions". At present, the classification of prescriptions is mainly based on clinical experience judgment, but there are some problems in manual judgment, such as lack of unified criteria, labor consumption, and difficulty in verification. In the construction of a database of integrated traditional Chinese and western medicine for the treatment of coronavirus disease 2019(COVID-19), our research group tried to classify real-world herbal prescriptions using a similarity matching algorithm. The main steps include 78 target prescriptions are determined in advance; four levels of importance labeling shall be carried out for the drugs of each target prescription; the combination, format conversion, and standardization of drug names of the prescriptions to be identified in the herbal medicine database; calculate the similarity between the prescriptions to be identified and each target prescription one by one; prescription discrimination is performed based on the preset criteria; remove the name of the prescriptions with "large prescriptions cover the small". Through the similarity matching algorithm, 87.49% of the real prescriptions in the herbal medicine database of this study can be identified, which preliminarily proves that this method can complete the classification of herbal prescriptions. However, this method does not consider the influence of herbal dosage on the results, and there is no recognized standard for the weight of drug importance and criteria, so there are some limitations, which need to be further explored and improved in future research.

Curing processes for carbon-fiber-reinforced polymer composites via microwave heating are promising alternatives to conventional thermal curing because this technology results in nonhomogeneous temperature distributions, which hinder its further development in industries. This paper proposes a novel method for improving heating homogeneities by employing three-dimensional motion with respect to the prepreg laminate used in the microwave field by using a recently developed microwave system. The maximum temperature deviation on the surface of the laminate can be controlled within 8.7 °C during the entire curing process, and it produces an average heating rate of 1.42 °C/min. The FT-IR analyses indicate that microwave heating would slightly influence hydroxyl and methylene contents in the cured laminate. The DMA measurements demonstrate that the glass transition temperatures can be improved by applying proper microwave-curing processes. Optical microscopy and mechanical tests reveal that curing the prepreg laminate by using a multistep curing process that initially cures the laminate at the resin's lowest viscosity for 10 min followed by curing the laminate at a high temperature for a short period of time would be favorable for yielding a sample with low void contents and the desired mechanical properties. All these analyses are supposed to prove the feasibility of controlling the temperature difference during microwave-curing processes within a reasonable range and provide a cured laminate with improved properties compared with conventional thermally cured products.
RESUMEN
OBJECTIVE: The aim for this trial was to preliminarily evaluate the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) for bone loss in patients with immobilization after surgical fixation of ankle and foot fractures. METHODS: A total of 80 patients with immobilization after surgical fixation of ankle and foot fractures were randomly divided into an intervention group (n=40) or control group (n=40). The intervention group was given TEAS treatment combined with routine orthopedic treatment, and the control group was given only routine orthopedic treatment. The CT attenuation values, bone turnover markers (ALP, PINP, BGP, CTX, Ca/Cr), bone mineral density (BMD), blood phosphorus, and blood calcium were observed and compared between the two groups at 8 weeks. This was a prospective study. The protocol was registered in the Chinese clinical trial registry (No. ChiCTR2000039944). RESULTS: The CT attenuation values of the intervention group decreased more than those of the control group (P<0.05), however the between group differences in ALP, BGP, Ca/Cr, CTX and BMD (all P>0.05) were not statistically significant. Three mild adverse events were recorded. CONCLUSION: TEAS treatment may confer additional benefits for bone loss in patients with immobilization after surgical fixation of ankle and foot fractures. Since this was a pilot study, the efficacy of TEAS requires further evaluation through full-scale randomized controlled trials.
RESUMEN
This study aims to explore the efficacy and safety of Lianhua Qingwen preparations combined with Oseltamivir in the treatment of influenza patients. PubMed, Cochrane Library, EMbase, SinoMed, CNKI, Wanfang, and VIP were searched for the randomized controlled trials(RCTs) involving the comparison between the influenza patients treated with Lianhua Qingwen preparations combined with Oseltamivir and those treated with Oseltamivir alone. Fever clearance time was taken as the primary outcome indicator. Clinical effective rate(markedly effective and effective), time to muscle pain relief, time to sore throat relief, time to cough relief, time to nasal congestion and runny nose relief, time to negative result of viral nucleic acid test, and adverse reactions were taken as the secondary outcome indicators. The data were extracted based on the outcome indicators and then combined. The Cochrane collaboration's tool for assessing risk of bias was used to evaluate the quality of a single RCT, and the grading of recommendations assessment, development and evaluations(GRADE) system to assess the quality of a single outcome indicator. RevMan 5.3 was employed to analyze data and test heterogeneity. Finally, 16 RCTs involving 1 629 patients were included for analysis. The Meta-analysis showed that Lianhua Qingwen preparations combined with Oseltamivir was superior to Oseltamivir alone in the treatment of influenza in terms of clinical effective rate(RR=1.16, 95%CI [1.12, 1.20], P<0.000 01), fever clearance time(SMD=-2.02, 95%CI [-2.62,-1.41], P<0.000 01), time to muscle pain relief(SMD=-2.50, 95%CI [-3.84,-1.16], P=0.000 2), time to sore throat relief(SMD=-1.40, 95%CI [-1.93,-0.85], P<0.000 01), time to cough relief(SMD=-1.81, 95%CI [-2.44,-1.19], P<0.000 01), time to nasal congestion and runny nose(SMD=-2.31, 95%CI [-3.61,-1.01], P=0.000 5), and time to negative result of viral nucleic acid test(SMD=-0.68, 95%CI [-1.19,-0.16], P=0.01). However, due to the low quality of the trials, the above conclusions need to be proved by more high-quality clinical studies. In addition, we still need to attach importance to the adverse reactions of the integrated application of Chinese and western medicines.

OBJECTIVE: To perform a systematic review to assess the effectiveness and safety of Reduning Injection versus neuraminidase inhibitors in treatment of influenza. METHODS: The MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), Chinese Bio-medical Literature and Retrieval System (Sinomed), China National Knowledge Infrastructure Database (CNKI), China Science and Technology Journal Database (VIP), Wanfang Data Knowledge Service Platform and ClinicalTrails.gov were systematically searched from inception dates to May 2021 for randomized controlled trials (RCTs) exploring Reduning Injection alone or in combination with neuraminidase inhibitors in patients with influenza. Statistical analysis was performed using RevMan 5.4 and Stata 15.1. The qualities of the involved studies were assessed by the risk of bias according to the Cochrane handbook. The evidence quality of each outcome was evaluated by GRADEpro GDT. RESULTS: Twelve trials with 1,460 patients were included. The included studies had a certain unclear or high risk of bias. Reduning Injection appeared to be more effective in shortening the fever clearance time (MD: -16.20 h, 95% CI: -19.40 to -12.99, 7 trials, 814 patients, I2=94%, very low certainty), fever alleviation time (MD: -4.09 h, 95% CI: -4.22 to -3.96, 3 trials, 366 patients, I2=0%, low certainty), cough alleviation time (MD: -21.34 h, 95% CI: -41.56 to -1.11, 2 trials, 228 patients, I2=89%, very low certainty), fatigue alleviation time (MD: -31.83 h, 95% CI: -36.88 to -26.77, 2 trials, 270 patients, I2=0%, low certainty), sore throat alleviation time (MD: -28.66 h, 95% CI: -32.23 to -25.10, 1 trial, 150 patients, low certainty), and improving the total effective rate (RR: 1.15, 95% CI: 1.06 to 1.25, 10 trials, 1,074 patients, I2=76%, very low certainty). Besides, Reduning Injection seemed generally safe. CONCLUSIONS: This study provided low or very low evidence indicating Reduning Injection may be effective in the treatment of influenza and might be safe. Further rigorously designed studies are needed to confirm the effectiveness and safety of Reduning Injection and support it as a recommendation for influenza.

BACKGROUND: To assess the effectiveness and safety of moxibustion for post-stroke depression (PSD). METHODS: A search was conducted in the following English and Chinese databases: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature (CBM), VIP and Wanfang. The outcomes included Hamilton Depression Rating Scale (HAMD), effective rate, and Modified Edinburgh-Scandinavian Stroke Scale (MESSS) scale. The formulation of search strategy, data extraction, and quality evaluation of involved studies was performed according to Cochrane handbook guidelines. The software RevMan 5.4 and Stata 16 were used for data analysis. The evidence quality of each outcome was evaluated by GRADEpro guideline development tool (GDT). RESULTS: A total of 14 trials with 863 participants were included. A certain risk of bias of unclear or high was detected in the included studies. Compared with the control group, adding moxibustion could change the value of HAMD [standardized mean difference (SMD) =-1.17; 95% confidence interval (CI): -1.55 to -0.79; I2=85.5%; P<0.01] and the effective rate [risk ratio (RR) =1.22; 95% CI: 1.13 to 1.32; I2=0.0%; P=0.56], and the differences in the MESSS scale (SMD =-0.72; 95% CI: -1.06 to -0.38; I2=0.0%; P=0.80) had statistical differences. The certainty was low in effective rate, and very low in HAMD and MESSS. Besides, moxibustion was shown to be generally safe. DISCUSSION: This review found that moxibustion may be an effective intervention for PSD. However, the results of this study have a certain limitation. The benefits of moxibustion for PSD need to be confirmed in the future by more high-quality randomized controlled trials (RCTs).

Since narrative medicine was introduced in China, it has been widely used in medical education and clinical practice. The research on narrative medicine in China is especially characterized by its combination with traditional Chinese medicine(TCM). At present, the research on narrative medicine in China is still in the stage of small-scale practicing and theory advocating. Besides, there is also a lack of guidance on experimental design methodology for clinical application, which leads to few high-quality studies in this field. The present study reviewed the current high-quality research on narrative medicine to discuss the value and prospects of mixed methods research in narrative medicine. In addition, the common design, application procedures, and notes of mixed methods research were explained to provide references for the extensive applications of narrative medicine in the medical field, especially TCM clinical practice, education, and scientific research.

INTRODUCTION: Fracture is a disease with a high incidence worldwide. Foot and ankle fractures are common among fractures of the lower extremities. Foot and ankle fractures usually require surgical fixation and a period of fixed treatment, which can lead to decreased bone density. Although transcutaneous electrical acupoint stimulation (TEAS) is widely used for movement system diseases, there is minimal evidence to show the effectiveness of TEAS on patients after surgical fixation of ankle and foot fractures. This trial aims to evaluate whether TEAS can reduce bone loss in patients with immobilisation after ankle and foot fractures. METHODS AND ANALYSIS: A randomised controlled trial will be conducted in which 60 patients will be randomly divided into two groups: (a) the control group will be treated according to the routine procedures of basic orthopaedics treatment; (b) in the treatment group, bilateral SP36, BL23 and ST36 will be performed on the basis of the control group, and the test will be performed for 30 min every other day for a total of 8 weeks. Bone turnover markers will be used as primary outcome. Secondary outcomes are composed of blood phosphorus, blood calcium and bone mineral density. Treatment safety will be monitored and recorded. ETHICS AND DISSEMINATION: This trial is approved by the Ethics Committee of Beijing University of Chinese Medicine (2020BZYLL0611) and the Ethics Committee of Beijing Luhe Hospital (2020-LHKY-055-02), and inpatients who meet the following diagnostic and inclusion criteria are eligible to participate in this study.

BACKGROUND: There are limited data on the clinical benefits of adding surgical resection in patients with recurrent or metastatic gastrointestinal stromal tumors (GISTs). This protocol outlines the planned scope and methods for a systematic review and meta-analysis update that will compare the clinical outcomes of surgical resection combined with tyrosine kinase inhibitor (TKI) with TKI treatment alone in patients with recurrent or metastatic GISTs. METHODS: This review will update a previously published systematic review by our team. This protocol is presented in accordance with the PRISMA-P guideline. PubMed, Embase, and Cochrane Central Register of Controlled Trials will be systematically searched and supplemented by a secondary screening of the references of all included studies. We will include randomized controlled trials (RCTs) and non-randomized studies (NRS) in this review update. The outcomes evaluated will be overall survival and progression-free survival. Two reviewers will independently screen and select studies, extract data from the included studies, and assess the risk of bias of the included studies. Data extracted from RCTs and NRS will be analysed and reported separately. Preplanned subgroup analyses and sensitivity analyses are detailed within this protocol. The strength of the body of evidence will be assessed using GRADE. DISCUSSION: This systematic review and meta-analysis update will provide a current assessment of the evidence for the role of surgery in patients with recurrent or metastatic advanced GISTs. These findings will be used by the Chinese Society of Clinical Oncology (CSCO) GIST guideline recommendations on surgical treatment for recurrent or metastatic advanced GIST patients in China. SYSTEMATIC REVIEW REGISTRATION: This protocol was prospectively registered in the Open Science Framework Registry ( https://osf.io/xus7m ).

BACKGROUND: Traditional Chinese medicine (TCM) may improve the prognosis management of cholelithiasis patients after gallbladder-preserving lithotripsy. To explore the evidence for this view, we systematically reviewed the efficacy and safety of TCM for improving the prognosis of cholelithiasis after gallbladder-preserving lithotripsy and performed functional pathway enrichment analysis of TCM target genes. METHODS: In this systematic review (SRs), we searched six Chinese or international databases to collect randomized controlled clinical trials (RCTs) of TCM in preventing the recurrence of cholelithiasis after gallbladder-preserving lithotripsy. The literature was independently screened by 2 reviewers, who then extracted the data. The Cochrane risk-of-bias and Grading of Recommendations, Assessment, Development and Evaluations (GRADE) tools were used to assess the included studies' risk of bias and quality of evidence, respectively. And, the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses would be conducted on the TCM prescriptions in the included literature to find the effective component and mechanism of TCM in the prognosis management of gallbladder-preserving lithotripsy. Analysis in this research would be conducted by R 3.5.2 software. RESULTS: A total of 1,024 articles were retrieved, and 9 RCTs involving 926 participants were included after the step-by-step screening. The risk of bias for each important outcome in all the studies was "uncertain". The meta-analysis showed that compared with blank control, TCM prevented cholelithiasis by decreasing the recurrence rate, complications incidence, gallbladder wall thickness, and gallbladder contraction degree. But, there were no significant differences in the rate of the adverse reaction. The result of the GO and KEGG analysis revealed that the mechanism of prevention of TCM in gallstone recurrence may be related to the cholesterol metabolic pathway and that naringin from Glycyrrhiza may be the effective component in the prevention of recurrence. CONCLUSIONS: Existing evidence suggests that the use of TCM may reduce the recurrence rate after gallbladder-preserving lithotripsy and this effect may be related to the flavonoid glycoside naringin from Glycyrrhiza uralensis, but more RCTs with high quality in this area may be needed to have a robust conclusion.

OBJECTIVE: To describe and record the evolution of EBM in China. STUDY DESIGN AND SETTING: We conducted the study following the general methodology of oral history. The interviews were done at Lanzhou University, between 18th and 22nd April 2019 using pre-defined questions. All interviews were videorecorded. Two investigators extracted and analyzed the information from the interviews independently. RESULTS: One international expert and ten Chinese experts participated in the interviews. After the introduction of EBM in China in the mid-1990s, more than 20 EBM centres have been established. According to the interviewees, Gordon Guyatt, David Sackett and Iain Chalmers are the international experts who played the most important role in the development of EBM in China. China has contributed to EBM on the international level by conducting systematic reviews, developing reporting checklists, and introducing the principles of EBM into Traditional Medicine. The Chinese Cochrane Centre and the EBM Centre of Lanzhou University were ranked the top two EBM Centres in China by the interviewees. CONCLUSION: EBM has been developing in China for nearly a quarter of a century. Many achievements have been reached, however, EBM is still facing many challenges in China, including shortages of funding support and personnel, as well as limited local high-quality evidence.

To sort out the key points in "PICOS" design of clinical trial scheme for influenza, and optimize the clinical trial scheme of Chinese patent medicine in the treatment of influenza by strictly following the principle of evidence-based medicine, focusing on the clinical practice of the disease, and highlighting the characteristics of traditional Chinese medicine. "The design of a randomized, double-blind, positive parallel control study of a certain herbal preparation for the treatment of non-severe influenza" was taken as an example in this study, and the key points in the clinical trial design of Chinese patent medicine for the treatment of influenza were specifically discussed from six aspects, including the type of study, object of study, intervention measures, control measures, outcome indicators and frequently asked questions in test design. From methodological suggestions, in the design scheme of clinical trial on efficacy and safety of Chinese patent medicine in the treatment of influenza, the randomized controlled study should be the first choice for type of study; the inclusion criteria should define both the diagnostic criteria of Western medicine and the syndromes of traditional Chinese medicine(TCM); the exclusion criteria should include a comprehensive list of confounding factors and special circumstances lea-ding to bias in the study results; the interventions should be based on a well-defined dosing programme; internationally recognized positive drugs or guidelines should be used as control measures, with median antipyretic time as the main outcome indicator. For the evalua-tion of curative effect, disease symptom scale can be set, and the TCM syndrome scoring scale was carefully used in this study, with time nodes set for the efficacy evaluation standard. The full name of the drugs should be written in the regulations on combined drug use and prohibited drug use.

Maternal food restriction (MFR) during pregnancy leads to pulmonary dysplasia in the newborn period and increases susceptibility to diseases, such as asthma and chronic lung disease, later in life. Previous studies have shown that maternal electro-acupuncture (EA) applied to "Zusanli" (ST 36) could prevent the abnormal expression of key lung developmental signaling pathways and improve the lung morphology and function in perinatal nicotine exposed offspring. There is a significant overlap in lung developmental signaling pathways affected by perinatal nicotine exposure and MFR during pregnancy; however, whether maternal EA at ST 36 also blocks the MFR-induced lung phenotype is unknown. Here, we examined the effects of EA applied to maternal ST 36 on lung morphology and function and the expression of key lung developmental signaling pathways, and the hypercorticoid state associated with MFR during pregnancy. These effects were compared with those of metyrapone, an intervention known to block MFR-induced offspring hypercorticoid state and the resultant pulmonary pathology. Like metyrapone, maternal EA at ST 36 blocked the MFR-induced changes in key developmental signaling pathways and protected the MFR-induced changes in lung morphology and function. These results offer a novel and safe, nonpharmacologic approach to prevent MFR-induced pulmonary dysplasia in offspring.

Antiviral Oral Liquid is modified on the basis of Baihu Decoction in Treatise on Febrility Diseases by ZHANG Zhongjing and Qingwen Baidu Yin in Qing Dynasty, with effects in clearing toxic heat, repelling dampness and cooling blood. It is widely used in clinical treatment of common colds, influenza and upper respiratory tract infection, mumps, viral conjunctivitis and hand-foot-mouth disease, with a good clinical efficacy and safety. Based on a questionnaire survey of clinicians and a systematic review of study literatures on Antiviral Oral Liquid, the international clinical practice guidelines development method was adopted to analyze the optimal available evidences and expert experiences in the "evidence-based, consensus-based and experience-based" principles. The consensus was jointly reached by more than 30 multidisciplinary experts nationwide, including clinical experts of traditional Chinese and Western medicine in the field of respiratory diseases and infectious diseases, and methodological experts. In the study, literatures were retrieved based on clinical problems in the clinical survey as well as PICO clinical problems. The GRADE system was used for the classification and evaluation of evidence, and fully combined with clinical expert experience, so as to reach expert consensus by the nominal grouping method. This expert consensus recommended or suggested indications, usage and dosage, course of treatment, intervention time for treatment, and the safety and precautions of Antiviral Oral Liquid for treatment of influenza, and can provide reference for the rational use of this drug in clinical practice.
