ABSTRACT

OBJECTIVE@#To explore the efficacy and safety of Zhuang medicine medicated thread moxibustion (ZMTM) on psoriasis vulgaris.@*METHODS@#A multicenter, randomized, parallel controlled clinical trial was designed. A total of 241 outpatients with psoriasis vulgaris were randomly divided into a control group (120 cases) and a treatment group (121 cases) using a central block randomization from June 2015 to May 2018. The control group was treated with Western medicines alone including pidotimod dispersible tablets, vitamin B compound tablets, and compound cod liver oil-zinc oxide ointment. The treatment group was treated with ZMTM every 2 days combined with Western medicines. The two groups received continuous intervention for 30 days. The primary outcome was Psoriasis Area and Severity Index (PASI), and the secondary outcomes included Itch Rating Scale, Dermatology Quality of Life Index (DLQI), Hamilton Anxiety Rating Scale (HAMA), as well as PASI response rate. Meanwhile, adverse events were evaluated during the whole clinical trial. Follow-up was carried out 30 days after treatment.@*RESULTS@#There were 5 cases of shedding in this trial. In intention-to-treat analysis, 236 cases were included and each group contained 118 cases. On the 30th and 60th days, PASI scores of patients in each group were significantly lower than that at baseline (P<0.01) and the PASI score reduction of the treatment group was greater than that of the control group (P<0.01). Itch Rating Scale, DLQI, and HAMA scale were decreased in both groups after treatment, and the treatment group showed a better therapeutic effect (P<0.01). The response rates of PASI 50 and 75 were significantly higher than those in the control group [81.4% (96/118), 43.2% (51/118) vs. 41.5% (49/118), 11.0% (13/118), respectively, P<0.05]. During follow-up, the improvements in scores of PASI, Itch Rating Scale, DLQI, and HAMA of the treatment group were significantly greater than those of the control group (P<0.01). The response rates of PASI 50 and 75 in the treatment group were significantly higher than those in the control group, respectively (both P<0.05). No obvious adverse reaction was found in either group.@*CONCLUSION@#ZMTM combined with Western medicines showed a better therapeutic effect in the treatment of psoriasis vulgaris without obvious adverse reaction. (Trial Registration No. ChiCTR-IOR-16008159).

ABSTRACT

OBJECTIVE@#To investigate the expression and clinical significance of miR-424 and miR-765 in patients with multiple myeloma (MM).@*METHODS@#The eighty-one MM patients admitted to Sanya Central Hospital from January 2017 to July 2020 were divided into phase Ⅰ (n=16), phase Ⅱ (n=25) and phase Ⅲ (n=40) according to the international staging system, while they were divided into IgG type (n=46), IgA type (n=19), light chain type (n=10) and non secretory type (n=6) according to the results of immunotyping. Another 50 healthy normal persons in the same period were selected as the control group. The levels of serum miR-424, miR-765 and Cystatin C (Cys-C) were measured in each group. The diagnostic value of serum miR-424, miR-765 and Cys-C in MM was estimated by ROC curve. Pearson correlation was used to analyze the correlation between serum levels of miR-424, miR-765 and Cys-C in MM patients.@*RESULTS@#The serum levels of miR-424 (2.74±1.30 vs 0.85±0.26), miR-765 (2.05±0.82 vs 0.63±0.17) and Cys-C [(2.18±0.86 vs 0.72±0.15) mg/L] in MM group were significantly higher than those in control group (P<0.001). The serum levels of miR-424 (5.08±2.36 vs 1.12±0.34, 2.24±0.93), miR-765 (3.50±1.52 vs 0.74±0.20, 1.78±0.65) and Cys-C [(3.81±1.30 vs 0.92±0.24, 1.68±0.55) mg/L] in MM patients at stage Ⅲ were significantly higher than those in patients at stage Ⅰ and Ⅱ (P<0.001). Also the serum levels of the three molecules in phase II were significantly higher than those in phase I (P<0.001). The serum levels of miR-424 and miR-765 in MM patients at IgG type were significantly higher than those at IgA, light chain and non secretory types (P<0.001). ROC curve analysis showed that the area under the curve (0.952,95%CI: 0.890-0.993) was greatest for the combination of miR-424, miR-765 and Cys-C for diagnosis of MM, and its sensitivity and specificity were 95.0% and 87.2%. The results of correlation analysis showed that the serum levels of miR-424 and miR-765 were positively correlated with Cys-C (r=0.795,r=0.760).@*CONCLUSION@#The serum levels of miR-424 and miR-765 in MM patients are significantly increased in the pattern increasing with the progression of MM stage. Combined with Cys-C, miR-424 and miR-765 have high value in the diagnosis of MM.

ABSTRACT

Traditional Chinese medicine(TCM) carries the experience and theoretical knowledge of the ancients, and the use of "toxic" Chinese medicines is a major feature and advantage of TCM. "Toxic" Chinese medicines have unique clinical value and certain medication risk under the guidance of TCM theories such as compatibility for detoxification and treatment based on syndrome differentiation. In recent years, the safety events of Chinese medicines have occurred frequently, which has made the safety of Chinese medicine a public concern in China and abroad. However, limited by conventional cognitive laws and technical methods, basic research on toxicity of Chinese medicines fails to be combined with the clinical application. As a result, it is difficult to identify the clinical characteristics of, predict toxic and side effects of, or form a universal precise medication regimen for "toxic" Chinese medicines, which restricts the clinical application of them. In view of the problem that the toxicity of "toxic" Chinese medicines is difficult to be predicted and restricts the clinical application, the evidence-based research concept will provide new ideas for safe applcation of them in clinical practice. The integrated development of multiple disciplines and techniques in the field of big data and artificial intelligence will also promote the renewal and development of the research models for "toxic" Chinese medicines. Our team tried to propose the academic concept of evidence-based Chinese medicine toxicology and establish the data-intelligence research mode for "toxic" Chinese medicines and the intelligent risk prediction method for medicinal combination in the early stage, which provided methodological supports for solving the above problem. Thus, on the basis of summarizing the research status and problems of the clinical medication regimen of "toxic" Chinese medicines, our team took the evidence-based toxicology of TCM as the core concept, and tried to construct the multiple-evidence integrated evaluation and prediction method for "toxic" Chinese medicine, so as to guide the establishment of the non-toxic medication regimen of "toxic" Chinese medicines. Specifically, through the analysis of multivariate data obtained from the basic research, the evidence-based toxicology database of Chinese medicines and the individualized "toxicity-effect" intelligent prediction platform were built based on the disease-syndrome virtual patients, so as to identify the clinical characteristics and risks of "toxic" Chinese medicines and develop individualized medication regime. This study is expected to provide a methodological reference for the establishment of medication regimen and risk prevention strategy for "toxic" Chinese medicines. The method established in this study will bridge clinical research and basic research, enhance the transformation of the scientific connotation of attenuated compatibility, promote the development of evidence-based Chinese medicine toxicology, and ensure the clinical safety of "toxic" Chinese medicines.

ABSTRACT

It was pointed out in Opinions on Promoting the Inheritance, Innovation and Development of Traditional Chinese Medicine issued by the State Council in 2019 that 100 varieties of traditional Chinese medicine(TCM) with unique curative effects should be screened out within about three years. Due to the multi-component and multi-target mechanisms of TCM varieties, it is difficult to directly and simply evaluate their multi-dimensional clinical value using methods applicable to chemical or biological agents. The heterogeneity of outcomes for similar TCM makes it difficult to determine the advantages of similar products. The fuzzy comprehensive evaluation method that is developed on the basis of core outcome set and fuzzy mathematics for clinical efficacy evaluation of TCM may solve these problems. This study developed a fuzzy comprehensive evaluation model for the clinical efficacy evaluation of Chinese patent me-dicines for coronary heart disease and angina pectoris, and selected the previous normative studies with complete or incomplete data for verifying the model application. The results showed that original studies with complete data failed to evaluate and compare the comprehensive efficacy of different interventions. The original research only mentioned the advantages and disadvantages of different interventions in different aspects. The comprehensive clinical efficacy of three different interventions obtained through fuzzy comprehensive evaluation was all graded as level Ⅱ. The original research with incomplete data drew the same conclusions as the fuzzy comprehensive evaluation, and the results of fuzzy comprehensive evaluation can provide more comprehensive information. Therefore, the fuzzy comprehensive evaluation shows the products with overall advantages of clinical efficacy, which may become a feasible method for the screening of TCM.

ABSTRACT

Objective@#To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on the pregnancy outcomes of in vitro fertilization-embryo transfer (IVF-ET) based on the available clinical evidence.@*METHODS@#We searched PubMed, MEDLINE, EMBASE, Cochrane Library, CNKI, VIP, CBM and Wanfang Database up to February 2021 for published randomized controlled trials (RCT) relevant to TEAS for the improvement of the pregnancy outcomes of IVF-ET. We performed literature screening, data extraction and quality evaluation according to the inclusion and exclusion criteria, followed by a meta-analysis with the RevMan 5.3 software.@*RESULTS@#A total of 2 206 cases of IVF-ET from 9 RCTs were included, 1 018 in the TEAS group and 1 188 in the control. The clinical pregnancy rate was significantly higher in the TEAS than in the mock TEAS and non-TEAS control groups (RR = 1.85, 95% CI: 1.42-2.42, P < 0.001; RR = 1.23, 95% CI: 1.10-1.39, P = 0.0004), and so was it before and after oocyte retrieval (RR = 1.50, 95% CI: 1.03-2.17, P = 0.03; RR = 1.47, 95% CI: 1.12-1.92, P = 0.005). The TEAS group also showed dramatically improved embryo implantation rate (RR = 1.49, 95% CI: 1.24-1.79, P < 0.0001) and live birth rate (RR = 1.44, 95% CI: 1.04-1.98, P = 0.03) compared with the control.@*CONCLUSIONS@#As a safe and non-invasive treatment, TEAS can significantly improve the pregnancy outcomes of IVF-ET, with definite effectiveness. /.

ABSTRACT

In order to standardize the clinical diagnosis and treatment decision-making with traditional Chinese medicine for pa-tients of coronavirus disease 2019(COVID-19) and put the latest clinical study evidence into clinical practice, the international trust-worthy traditional Chinese medicine recommendations( TCM Recs) working group started the compilation of Living Evidence-based Guideline for Combination of Traditional Chinese and Western Medicine for Treatment of COVID-19 on the basis of the standards and re-quirements of WHO handbook, GRADE and RIGHT. This proposal mainly introduces the formulation methods and processes of the living guidelines in details, such as the composition of the working group, the collection and identification of clinical issues and out-comes, the production of the living systematic review and the consensus of recommendations. The guidelines will continue to monitor the clinical study evidences of TCM in the prevention and treatment of COVID-19, and conduct regular evidence updating, retrieval and screening. When there is new study evidence, the steering committee will evaluate the possibility of the evidence to change clinical practice or previous recommendations, so as to decide whether the recommendations for the guidelines shall be implemented or upda-ted. The main criteria considered in the guideline updating are as follows:(1) There are new high-quality randomized controlled trial(RCT) evidences for TCM uninvolved in the previous edition of the guidelines;(2) as for the TCM involved in the guidelines, living sys-tematic review shows that new evidence may change the direction or strength of the existing recommendations. The specific implementation of the living evidence-based guidelines will take this proposal as the study basis and framework, in order to ensure the standardization of the formulation process and methods. This will be the first exploration of the methodology for living guidelines in the field of TCM.

ABSTRACT

OBJECTIVE@#To describe and analyze the status quo of cardiovascular clinical practice guidelines or expert consensuses including both Chinese medicine (CM) and integrative medicine, through systematic literatures searching and quality assessment.@*METHODS@#Data bases including Chinese Biomedical Literature Database, the China National Knowledge Infrastructure, Wanfang Data, China Science and Technology Journal Database were searched for published CM or integrative cardiovascular clinical practice guidelines or expert consensuses. The website www. medlive.cn was also retrieved as supplementary. The clinical practice evaluation tool AGREE II was used to assess the quality of included guidelines or consensuses.@*RESULTS@#A total of 31 relevant clinical practice guidelines or expert consensuses were included, covering diagnosis, treatment, Chinese patent and patient fields. Common cardiovascular diseases like coronary heart diseases, heart failure and arrhythmia were also involved. Through analysis it was found that both the quantity and quality of included guidelines have been improved year by year. A total of 4 evidence-based clinical practice guideline has been found, one of which was a guideline project plan. Except that, the remaining 27 reports were all consensus-based guidelines. The scores of each field, from highest to lowest, were clarity of presentation (58%), scope and purpose (54%), stakeholder involvement (28%), rigor of development (21%), applicability (13%) and editorial independence (8%).@*CONCLUSIONS@#Although clinical practice guidelines in cardiovascular domain of Chinese have gained increasing concern, with both quantity and quality improved, there is still huge gap in methodology and reporting standards between CM guidelines and international ones. On the one hand, it is essential to improve and standardize the methodology of developing CM guidelines. On the other hands, the evaluation system of evidence and recommendation with CM characters should be developed urgently.

ABSTRACT

Clinical trial outcome reporting differs between studies integrating traditional Chinese medicine (TCM) and Western medicine, so that some clinical trials are not eligible for inclusion in a systematic review. The excluded studies are therefore less widely disseminated, and even valid studies are less likely to yield impact. This problem may be addressed by developing core outcome sets (COSs) for integrative medicine in specific healthcare areas. The first stage of development is to define the scope of the COS for integrative medicine, the second stage is to establish the need for such a COS, and the third stage is to develop a protocol and register the COS. The final stage involves three steps: (i) development of a comprehensive list of outcomes (including efficacy outcomes and safety outcomes and TCM syndromes) using systematic review, qualitative or cross-sectional research, and reviews of package inserts and medical records; (ii) merging and grouping of outcomes within domains; (iii) conducting two rounds of Delphi survey and consensus meetings with a range of stakeholders. The final COS will include a general COS and core TCM syndrome- set. Development of COSs for clinical trials of integrative medicine may help to standardize outcome reporting and reduce publication bias in the future.

ABSTRACT

BACKGROUND@#The therapeutic evidence collected from well-designed studies is needed to help manage the global pandemic of the coronavirus disease 2019 (COVID-19). Evaluating the quality of therapeutic data collected during this most recent pandemic is important for improving future clinical research under similar circumstances.@*OBJECTIVE@#To assess the methodological quality and variability in implementation of randomized controlled trials (RCTs) for treating COVID-19, and to analyze the support that should be provided to improve data collected during an urgent pandemic situation.@*SEARCH STRATEGY@#PubMed, Excerpta Medica Database, China National Knowledge Infrastructure, Wanfang, and Chongqing VIP, and the preprint repositories including Social Science Research Network and MedRxiv were systematically searched, up to September 30, 2020, using the keywords "coronavirus disease 2019 (COVID-19)," "2019 novel coronavirus (2019-nCoV)," "severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2)," "novel coronavirus pneumonia (NCP)," "randomized controlled trial (RCT)" and "random."@*INCLUSION CRITERIA@#RCTs studying the treatment of COVID-19 were eligible for inclusion.@*DATA EXTRACTION AND ANALYSIS@#Screening of published RCTs for inclusion and data extraction were each conducted by two researchers. Analysis of general information on COVID-19 RCTs was done using descriptive statistics. Methodological quality was assessed using the risk-of-bias tools in the Cochrane Handbook for Systematic Reviews of Interventions (Version 5.1.0). Variability in implementation was assessed by comparing consistency between RCT reports and registration information.@*RESULTS@#A total of 5886 COVID-19 RCTs were identified. Eighty-one RCTs were finally included, of which, 45 had registration information. Methodological quality of the RTCs was not optimal due to deficiencies in five main domains: allocation concealment, blinding of participants and personnel, blinding of outcome assessment, incomplete outcome data, and selective reporting. Comparisons of consistency between published protocols and registration information showed that the 45 RCTs with registration information had common deviations in seven items: inclusion and exclusion criteria, sample size, outcomes, research sites of recruitment, interventions, and blinding.@*CONCLUSION@#The methodological quality of COVID-19 RCTs conducted in early to mid 2020 was consistently low and variability in implementation was common. More support for implementing high-quality methodology is needed to obtain the quality of therapeutic evidence needed to provide positive guidance for clinical care. We make an urgent appeal for accelerating the construction of a collaborative sharing platform and preparing multidisciplinary talent and professional teams to conduct excellent clinical research when faced with epidemic diseases of the future. Further, variability in RCT implementation should be clearly reported and interpreted to improve the utility of data resulting from those trials.

ABSTRACT

BACKGROUND@#The association of lipids and cancer has varied greatly among different cancer types, lipid components and study populations. This study is aimed to investigate the association of serum lipids and the risk of malignant lesions in esophageal squamous epithelium.@*METHODS@#In the "Endoscopic Screening for Esophageal Cancer in China" (ESECC) trial, serum samples were collected and tested for total cholesterol (TC), triglycerides, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol at the time of subject enrollment. Cases were defined as malignant esophageal lesions identified by baseline endoscopic examination or by follow-up to May 31, 2018. Controls were randomly selected using incidence density sampling in the same cohort. Conditional logistic models were applied to identify the association of serum lipids and the risk of malignant esophageal lesions. Effect modification was evaluated by testing interaction terms of the factor under assessment and these serum lipid indicators.@*RESULTS@#No consistent association between serum lipid levels and esophageal malignant lesions were found in a pooled analysis of 211 cases and 2101 controls. For individuals with a family history of esophageal cancer (EC), high TC, and LDL-C were associated with a significantly increased risk of having malignant lesions (odds ratio [OR]High vs. Low TC = 2.22, 95% confidence interval [CI]: 1.14-4.35; ORHigh vs. Low LDL-C = 1.93, 95% CI: 1.01-3.65). However, a negative association was observed in participants without an EC family history (ORHigh vs. Low TC = 0.69, 95% CI: 0.48-0.98, Pinteraction = 0.002; ORHigh vs. Low LDL-C = 0.50, 95% CI: 0.34-0.76, Pinteraction < 0.001).@*CONCLUSIONS@#In this study, we found that the association of serum lipids and malignant esophageal lesions might be modified by EC family history. The stratified analysis would be crucial for population-based studies investigating the association of serum lipids and cancer. The mechanism by which a family history of EC modifies this association warrants further investigation.

ABSTRACT

Objective:To investigate the difference of heart rate variability in cardioinhibitory type vasovagal syncope(VVS-CI) children with different body mass index(BMI).Methods:Clinical data of thirty-four children with syncope or pre-syncope were retrospectively analyzed, who visited specialist clinic for syncope and diagnosed as VVS-CI at the Second Xiangya Hospital of Central South University from January 2012 to December 2019.BMI was calculated based on height and weight, and divided into lean group(BMI≤18.4 kg/m 2, n=19) and normal group(BMI 18.5-23.9 kg/m 2, n=15). Heart rate variability(HRV) of 24 h dynamic electrocardiogram was analyzed using linear analysis method.Time domain index included SDNN, SDANN, rMSSD and pNN50.Frequency domain index included total power(TP), ultra low frequency power(ULF), very low frequency power(VLF), low frequency power(LF), high frequency power(HF) and LF/HF. Results:There was no significant difference in SDNN, SDANN and rMSSD between lean and normal group( P>0.05), but pNN50 increased in lean group( P<0.05). No significant differences were found in TP, ULF, LF, HF and LF/HF between two groups( P>0.05), while VLF was lower in lean group than that in normal group( P<0.05). There was no statistical difference in time domain index and frequency domain index between different gender between lean and normal group( P>0.05). SDNN, SDANN and LF were higher in<12 years old than those in≥12 years old in lean group( P<0.05). There was no statistical difference in rMSSD, pNN50, TP, ULF, VLF, HF and LF/HF( P>0.05). ULF increased and LF decreased in<12 years old compared to ≥12 years old in normal group( P<0.05). No statistical differences were found in SDNN, SDANN, rMSSD, pNN50, TP, VLF, HF and LF/HF( P>0.05). Conclusion:The autonomic nervous regulation function of VVS-CI children with low BMI and normal BMI is different, resulting in HRV difference.There were also differences in HRV between<12 years old and ≥12 years old with the same BMI.

ABSTRACT

Objective:To study the diagnostic efficacy and prognostic evaluation value of QT interval dispersion (QTd) in children and adolescents with cardioinhibitory vasovagal syncope (VVS-CI).Methods:From July 2010 to January 2020, 80 children and adolescents who received their first visit or admission to the Pediatric Syncope Clinic of The Second Xiangya Hospital of Central South University and definite diagnosed of VVS-CI due to syncope or presyncope were selected as the VVS-CI group, meanwhile, 80 children and adolescents who had physical examination in the hospital were selected as the control group.QT interval were measured by 12-lead electrocardiogram at the baseline.Results:(1) Comparison between the two groups: Compared with the control group, the VVS-CI group had a significantly lower heart rate ( P<0.05) and significantly longer QT interval, such as the maximum QT interval (QTmax), minimum QT interval (QTmin), QTd, corrected maximum QT interval (QTcmax) and corrected QT interval dispersion (QTcd) ( P<0.05). After follow-up 84 (45, 127) days, compared with the responsive group, the non-responsive group had a significantly longer QT interval, such as QTmax, QTd, QTcmax, corrected minimum QT interval (QTcmin)and QTcd ( P<0.05). (2) Diagnostic efficiency: QTmax, QTmin, QTd, QTcmax and QTcd had a certain diagnostic value in children and adolescents with VVS-CI ( P<0.001). QTd had the largest area under the curve (AUC) (0.914), and had a sensitivity of 86.30% and a specificity of 84.95% at the optimal cut-off value of 28.50 ms for VVS-CI diagnosis.(3) Prognostic evaluation value: QTmax, QTd, QTcmax, QTcmin, QTcd had an estimated value for the prognosis of VVS-CI in children and adolescents ( P<0.05 or 0.01). QTd had the largest AUC (0.906) and the best cut-off value was 34.50 ms, the sensitivity to predict response to VVS-CI intervention was 90.00%, and the specificity was 82.35%. Conclusion:QTd of electrocardiogram has a good estimation value in the diagnosis and prognosis of VVS-CI in children and adolescents.

ABSTRACT

Objective:To discuss the relationship between heart rate (HR) and heart rate differences (HRD) at different time points in head-up tilt test (HUTT) and the occurrence of postural tachycardia syndrome(POTS) in children and adolescents.Methods:A total of 217 children and adolescents diagnosed as POTS, who complained of syncope or presyncope, were chosen as POTS group (aged 6 to 16 years). During the same period, 73 healthy children and adolescents with matching gender and age were selected as control group.All subjects underwent HUTT from October 2000 to November 2019.Get HR (HR0, HR5, HR10) in baseline, HUTT 5 min and 10 min, HRD (HRD5, HRD10) of HR in HUTT 5 min and 10 min minus HR in baseline.Results:(1) HR5, HR10, HRD5, and HRD10 were higher in the POTS group than those in the control group( P<0.05). (2) Univariate Logistic regression: There was a correlation between HR5, HR10, HRD5, HRD10 and the risk of POTS( P<0.01). (3) Multivariable Logistic regression: For each additional unit of HRD5 and HRD10, the risk of POTS increased by 27% ( OR=1.27, 95% CI1.16 to 1.36) and 28% ( OR=1.28, 95% CI1.20 to 1.38). Conclusion:HR and HRD are related with the occurrence of POTS in children and adolescents, but HR and HRD at different time points of HUTT play the little role on the effect size of the occurrence of POTS.

ABSTRACT

Objective:To investigate the circadian rhythm of blood pressure and morning blood pressure surge (MBPS) in children with neurally mediated syncope (NMS).Methods:From July 2018 to June 2019, 135 cases [aged 3-16 years old (10.12±2.53) years old, with 74 males and 61 females] with unexplained syncope, presyncope, and symptoms such as headache, dizziness, chest pain, and chest tightness were collected in the Second Xiangya Hospital, Central South University for the first time.The 24 hour ambulatory blood pressure monitoring (24 h ABPM) was completed on the same day of the head-up tilt test (HUTT). Patients were divided into HUTT negative and positive groups, and dippers and non-dippers groups. MBPS (sleep-trough surge) was calculated and compared respectively.Results:(1) There were 51 patients in the HUTT positive group, including 27 patients with vasovagal syncope, 23 patients with postural orthostatic tachycardia syndrome, and 1 patient with orthostatic hypotension. In HUTT positive group, there were 22 cases (43.14%) of dippers and 29 cases of non-dippers.There were 84 patients in the HUTT negative group, there were 32 cases (38.10%) of dippers and 52 cases of non-dippers. There were no statistical significances in the dipper proportion between HUTT positive and negative group ( χ2=1.305, P>0.05). (2) Sleep-trough systolic blood pressure (SBP) surge was 1-45 mmHg [(15.97±8.03) mmHg](1 mmHg=0.133 kPa), and sleep-trough diastolic blood pressure (DBP) surge was -6-43 mmHg[(14.05±7.97) mmHg]. There were no statistical significances in sleep-trough surge between the HUTT negative and positive group (all P>0.05). (3) The age in the dipper group was higher than that in the non-dipper group [(10.72±2.20) years old vs. (9.72±2.66) years old, t=2.288, P<0.05]. The daytime average SBP [(110.20±8.33) mmHg vs.(105.54±7.51) mmHg, t=3.381, P<0.01], and morning peak SBP [(109.99±10.19) mmHg vs.(106.63±8.71) mmHg, t=2.045, P<0.05] of the dipper group were higher than those of the non-dipper group.The nighttime average SBP[(95.41±7.50) mmHg vs.(98.59±6.88) mmHg, t=2.540, P<0.01], nighttime average DBP[(48.61±4.52) mmHg vs.(52.28±4.65) mmHg, t=4.547, P<0.01], nocturnal minimum SBP[(89.62±8.18) mmHg vs.(93.60±7.38) mmHg, t=2.940, P<0.01], and nocturnal minimum DBP[(44.99±5.32) mmHg vs.(49.01±5.54) mmHg, t=4.205, P<0.01] of the dipper group were lower than that of the non-dipper group.Nocturnal SBP reduction rate [(13.42±2.68)% vs.(6.48±2.49)%, t=15.384, P<0.01], nocturnal DBP reduction rate[(19.98±4.92)% vs.(12.46±5.05)%, t=8.561, P<0.01], sleep-trough SBP surge[(20.37±8.30) mmHg vs.(13.03±6.36) mmHg, t=5.800, P<0.01], and sleep-trough DBP surge[(16.91±8.06) mmHg vs.(12.13±7.36) mmHg, t=3.554, P<0.01] of the dipper group were higher than those of the non-dipper group.

ABSTRACT

Objective:To investigate the relationship between body mass index (BMI) and response time of cardioinhibitory type vasovagal syncope (VVS-CI) in children.Methods:The clinical data of 56 children with syncope or pre-syncope were retrospectively analyzed and they visited specialist clinic for syncope and were diagnosed as VVS-CI in the Second Xiangya Hospital, Central South University from December 2012 to September 2019.Based on height and weight, BMI was calculated, and divided into low BMI group (35 cases) and normal BMI group (21 cases). Between the 2 groups, baseline heart rate, head-up tilt test (HUTT) positive response heart rate, baseline head-up tilt test (BHUT) positive response time, and sublingual nitroglycerin-provocated HUTT (SNHUT) positive response time were compared.The correlation between BMI and positive response time was analyzed.SPSS 22.0 software was applied for statistical analysis.Results:There were no significant differences in age, sex, duration of disease and number of syncope between the 2 groups (all P>0.05). No significant differences were found in baseline heart rate and positive response heart rate between the 2 groups [(78.5±15.3) times/min vs.(72.8±8.7) times/min, t=1.223, P=0.230; (44.0±13.9) times/min vs.(47.0±10.0) times/min, t=-0.664, P=0.511]. Compared with normal BMI group, BHUT positive patients/SNHUT positive patients were higher in low BMI group (27/8 cases vs.9/12 cases, χ2=4.839, P=0.027), and the positive response time of BHUT was shorter [(13.1±4.6) min vs.(23.7±9.5) min, t=-2.691, P=0.023]. There were no significant differences in SNHUT positive response time between the 2 groups ( P>0.05). Low BMI was correlated with BHUT positive response time ( r=0.750, P=0.005). Normal BMI was not associated with BHUT positive response time ( r=0.316, P=0.217). There was no correlation between low BMI and normal BMI and SNHUT positive response time ( r=0.177, P=0.431; r=0.021, P=0.940). Conclusions:Low BMI is positively correlated with BHUT positive response time of children with VVS-CI.The time it takes for syncope occurrence was shorter in children with low BMI than that in normal BMI.

ABSTRACT

Objective:To explore the effect of costunolide on sensitivity of chronic myeloid leukemia cell line K562/ADR to doxorubicin and its mechanism.Methods:K562/ADR cells in the logarithmic phase were used, and the cells were treated with different concentrations of costunolide, doxorubicin or costunolide combined with doxorubicin for 72 h. The cell proliferation was detected by CCK-8 method, the cell proliferation rate was calculated, and the half inhibitory concentration (IC 50) of the two drugs was obtained. The cells were treated with 10 μmol/L costunolide, 10 μmol/L doxorubicin or costunolide combined with doxorubicin for 48 h, the apoptotic rate was detected by flow cytometry, and the expression level of p38-MAPK pathway related proteins was detected by Western blot. Results:The cell proliferation rate in the costunolide combined with doxorubicin group was lower than that in the corresponding concentration of the two drugs alone groups, and the differences were statistically significant both ( P < 0.05). The IC 50 of doxorubicin for K562/ADR cells was (13.50±0.86) μmol/L, and costunolide was (7.30±0.55) μmol/L ( t = 7.044, P = 0.002). The results of flow cytometry showed that the apoptosis rate of K562/ADR cells in the 10 μmol/L costunolide combined with 10 μmol/L doxorubicin group was higher than that of the blank control group, costunolide alone group and doxorubicin alone group, and the differences were statistically significant [(19.68±3.21)% vs. (2.96±0.87)%, (9.34±2.89)%, (9.18±2.13)%, all P<0.01]. Compared with the 10 μmol/L costunolide alone group and the 10 μmol/L doxorubicin alone group, the expression of the apoptosis inhibitor protein bcl-2 in the two-drug combination group was down-regulated, and the expressions of bad, p-p38, cleaved-caspase-3 and cleaved-PARP proteins were up-regulated. Conclusion:Costunolide can enhance the inhibitory effect of doxorubicin on the proliferation of K562/ADR cells and promote doxorubicin-induced apoptosis, which may reverse the drug resistance of K562/ADR cells by regulating the p38-MAPK pathway.

ABSTRACT

Objective:To determine the change in the number of family planning technical services in Pudong New Area of Shanghai from 2011 through 2018, and provide scientific evidence for improving reproductive health care for women of childbearing age. Methods:Trend analysis was performed according to the data of family planning technical service and obstetric service records by all medical and health care facilities in Pudong New Area from 2011 through 2018. Results:Top four family planning operations were vacuum aspiration, intrauterine device (IUD) removal, IUD insertion and medical abortion. The average annual number of family planning operations was 77 320, which declined over years with an average reduction rate of 3.32%. The average reduction rate of contraceptive and induced abortion was 5.87% and 1.6%, respectively. The reduction rate of IUD insertion was higher than that of IUD removal. Vacuum aspiration was the leading method of induced abortion, accounting for 77.9%, in which 79.27% was performed with intravenous anesthesia. Among the women receiving induced abortion, majority of them were married and non-local residents. The ratio of induced abortion to the live birth decreased over years from 2011 through 2018. Conclusion:Number of family planning technical services in Pudong New Area of Shanghai decreases from 2011 through 2018. Vacuum aspiration and IUD removal are the main operations in family planning surgery. With the decrease of long-term medically controlled contraceptive and birth control measures, it is necessary to strengthen the correct and effective use of self-controlled contraceptive measures for women of childbearing age, especially for those non-local married women, so as to reduce unwanted pregnancies and repeated induced abortions.

ABSTRACT

To systemically evaluate the effect of Qishen Yiqi Dripping Pills combined with Western medicine on adverse cardiovascular events and quality of life after percutaneous coronary intervention(PCI). A total of 7 Chinese and English databases including CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library and Web of Science were searched by computer to collect the randomized controlled trials(RCTs) on Qishen Yiqi Dripping Pills combined with Western medicine in the treatment of patients with coronary heart disease after PCI with the retrieval time from the database establishment to April 1, 2020. Two researchers independently conducted li-terature screening, data extraction and bias risk assessment. Then, Meta-analysis was performed by using RevMan 5.3 software. A total of 31 RCTs were included, involving 3 537 patients. The results of Meta-analysis showed that in terms of major adverse cardiovascular events(MACE) after PCI, the combination of Qishen Yiqi Dripping Pills could significantly reduce the recurrence of angina pectoris, incidence of arrhythmia, heart failure and re-revascularization, and the effect was better than that of Western medicine treatment alone. However, there was no significant difference between the two groups in the improvement of non-fatal myocardial infarction, cardiac death, stent restenosis, stroke and other adverse cardiovascular events. In terms of improving left ventricular ejection fraction(LVEF), 6 min walking test(6 MWT), high-sensitivity C-reactive protein(hs-CRP) and Seattle angina pectoris scale(SAQ), the combination of Qishen Yiqi Dripping Pills and Western medicine treatment had obvious advantages over Western medicine treatment alone in increasing LVEF, 6 MWT and SAQ, and reducing the level of hs-CRP, with statistically significant differences. There were few adverse reactions in both groups, and there was no significant difference between the two groups. The main manifestations were gastrointestinal reactions, rash, gingiva and other small bleeding, and no serious adverse reactions occurred. The above reactions could disappear after drug withdrawal or symptomatic treatment. The application of Qishen Yiqi Dripping Pills combined with Western medicine in the treatment of patients after PCI could reduce the occurrence of MACE, improve the clinical efficacy, quality of life and prognosis in a safe and reliable manner. However, due to the quantity and quality limitations of included studies, more standardized, rigo-rous and high-quality clinical studies are still needed to further verify the above conclusions.
