Objective: To evaluate the clinical value of echocardiography in aortic valvuloplasty (AVP) in the low-age pediatric patients with congenital aortic valve stenosis. Methods: We retrospectively studied 39 low-age (at median of 23 months) patients with congenital aortic valve stenosis who received aortic valve repair in our hospital for their echocardiography information, and statistically analyzed the main indicator changes by 4 time points as pre-operation and 1 week, 1-3 months, 6-12 months after the operation respectively. Results: In our study, the bicuspid to tricuspid valve ratio was approximately at 5.5/1 and 2 patients died during peri-operative period. Compared with pre-operative time point, Doppler aortic valve peak velocity (Vmax ) and the mean aortic transvalvular pressure gradient (MPG) were reduced accordingly, for Vmax: (4.30 ± 0.73) m/s vs (2.65 ± 0.78) m/s, (2.93 ± 0.63) m/s, (3.01 ± 0.83) m/s,P<0.01, for MPG: (45.78 ± 15.19) mmHg vs (18.24 ± 10.08) mmHg, (21.01 ± 10.08) mmHg, (22.31 ± 13.41) mmHg. Compared with pre-operative time point, left ventricular ejection fractions (LVEF) were similar in 3 post-operative time points. Compared with 1 week post operative time point, left ventricular end-diastolic anteroposterior diameter (LVEDD) was increased at 6-12 months post-operative time point, the relative wall thickness (RWT) was decreased, bothP<0.05, and aorta valve regurgitation (AR) was increasedP<0.01. Pearson correlation analysis showed that aortic annulus (AA) inner diameter was positively related to LVEDD (r= 0.648,P<0.01), negatively related to Vmax (r= -0.205,P<0.05) and RWT was positively related to Vmax (r= 0.196,P<0.05). There were 6 patients with pre-operatively decreased LVEF, 1 of them died and the rest 5 with elevated LVEF at 6-12 months post-operative period,P<0.05. Conclusion: Echocardiograghy could be used as the ifrst choice of imaging method for diagnosing congenital aortic valve stenosis, it has the important role for in-operative monitoring and post-operative evaluation of AVP in relevant patients.

Various kinds of schiff base metal complexes have been proven to induce apoptosis of tumor cells. However, it remains largely unknown whether schiff base zinc complexes induce apoptosis in human cancer cells. Here, we synthesized a novel schiff base zinc coordination compound (SBZCC) and investigated its effects on the growth, proliferation and apoptosis of human osteosarcoma MG-63 cells. A novel SBZCC was synthesized by chemical processes and used to treat MG-63 cells. The cell viability was determined by CCK-8 assay. The cell cycle progression, mitochondrial membrane potential and apoptotic cells were analyzed by flow cytometry. The apoptosis-related proteins levels were determined by immunoblotting. Treatment of MG-63 cells with SBZCC resulted in inhibition of cell proliferation and cell cycle arrest at G1 phase. Moreover, SBZCC significantly reduced the mitochondrial membrane potential and induced apoptosis, accompanied with increased Bax/Bcl-2 and FlasL/Fas expression as well as caspase-3/8/9 cleavage. Our results demonstrated that the synthesized novel SBZCC could inhibit the proliferation and induce apoptosis of MG-63 cells via activating both the mitochondrial and cell death receptor apoptosis pathways, suggesting that SBZCC is a promising agent for the development as anticancer drugs.

This study aimed to comprehensively analyze and compare the differences of different clinical study types currently published in the safety evaluation of Xuebijing Injection. Six databases, namely the Cochrane Library, PubMed, EMbase, CNKI, VIP and Wanfang database, were electronically retrieved to collect all types of studies on the safety of Xuebijing Injection, including randomized controlled trials, case-controlled studies, cohort studies, systematic reviews, and centralized monitoring studies of clinical safety(hospital), in order to comprehensively and objectively evaluate the safety of Xuebijing Injection, and analyze the differences of different research results. A total of 211 literatures were included, involving a total of 46 384 patients treated with Xuebijing Injection, and 423 adverse reactions(ADRs) occurred. They included 191 randomized controlled trials, 3 cohort studies, 15 systematic reviews, and 2 centralized monitoring studies of clinical safety(hospital), and the incidence of adverse reactions was 2.54%(common), 2.31%(common), 0.95%(occasionally), and 0.50%(occasionally). More than half of the 423 cases of ADRs occurred in skin and adnexal system(151 cases) and gastrointestinal system(65 cases), including such manifestations as rash, skin itching, nausea and vomiting, diarrhea. The degree of ADRs was mild. Randomized controlled trials showed that the incidence of ADR was the highest when Xuebijing Injection was used for malignant tumor and multiple organ failure. And the systematic evaluation showed that the incidence of ADR was the highest when Xuebijing Injection was used for spontaneous peritonitis of liver cirrhosis. In conclusion, different study types could lead to significant differences in the results of drug safety evaluation. Sample size, study type, and quality control are the main factors for biased results. Due to large sample size and high-quality, centralized monitoring studies become the better clinical safety evaluation model of drugs at present, and full life cycle management could more objectively reflect drug safety and guide clinical rational drug use.

To evaluate the efficacy and safety of Compound Danshen Injection combined with Western medicine in the treatment of vascular dementia. Databases of Cochrane Library, PubMed, EMbase, CNKI, SinoMed, VIP, Wanfang Data were electronically retrieved for collecting randomized controlled trial(RCT)about vascular dementia treated with Western medicine alone or combined with Compound Danshen Injection from the year of database establishment to January 2020. Two researchers independently screened out li-teratures, extracted data, and evaluated the risk of bias for inclusion in the study. Meta-analysis was conducted using RevMan 5.3 software. A total of 5 RCTs were included, involving 588 patients, with 299 in treatment group and 289 in control group. Meta-analysis results showed that compared with Western medicine alone, Compound Danshen Injection combined with Western medicine was better in the effective rate(RR=1.23,95%CI[1.14,1.33],P<0.000 01), MMSE score(MD=3.54,95%CI[3.01,4.06],P<0.000 01), ADL score(MD=11.49,95%CI[8.05,14.93],P<0.000 01), the level of CRP(MD=-0.72,95%CI[-1.25,-0.20],P=0.007) and the level of IL-6(MD=-7.64,95%CI[-9.65,-5.63],P<0.000 01). Adverse reactions mainly included rash and skin prick, which did not affect the treatment effect. Based on the findings, the combination of Compound Danshen Injection in the treatment of vascular dementia could improve the effective rates, relieve the mental state damage and improve the daily living ability, with mild adverse reactions and a low incidence. However, due to the low quality of the included literatures, high-quality and large-scale randomized controlled trials are needed for further verification.

OBJECTIVEThis study was to investigate the mRNA expression of T-bet, GATA-3, ROR γt and Foxp3 mRNA in peripheral blood of patients with chronic lymphocytic leukemia (CLL) in different stages and explore their potential role in the pathogenesis and clinical diagnosis.
METHODSA total of 46 newly diagnosed and untreated patients with CLL was chosen as patient group, including 16 patients in the stage of Binet A, 15 in the stage of Binet B, and 15 in the stage of Binet C; 20 healthy persons were selected as controls. The quantitative fluorescence PCR was adopted to detect the mRNA expression of T-bet, GATA-3, RORγt and Foxp3 in peripheral blood mononuclear cell (PBMNC).
RESULTS(1) The expression of T-bet mRNA in patient group was lower than that in normal controls (P < 0.05), while the mRNA expression of GATA-3 mRNA, ROR γt, Foxp3 in CLL patients group were higher than that in normal controls (P < 0.05), and the ratio of T-bet/GATA-3 and RORγt/Foxp3 in CLL in patient group were lower than that in normal controls(P < 0.05); (2) The later the stage, the higher the mRNA expression of GATA-3 and Foxp3. The mRNA expression of GATA-3 in stage Binet B and stage Binet C of CLL patients were higher than that in stage Binet A (P < 0.05),and the mRNA expression of Foxp3 in stage Binet C was higher than that in stage of Binet A and Binet B (P < 0.05); the later the stage, the lower the ratio of T-bet/GATA-3 and RORγt/Foxp3. The ratio of T-bet/GATA-3 in stage of Binet A CLL patients was higher than that in stage Binet C (P < 0.05) and the ratio of RORγt/Foxp3 in stage of Binet A and stage of Binet B were higher than that in stage Binet C (P < 0.05).
CONCLUSIONThis study found in the level of transcription factors in CLL patients that with the process of disease, the balance shifts from Th1/Th2 and Th17/Treg to Th17 and Treg, and Treg cell may play a critical immunosuppressive role in the development of CLL.

Objective To evaluate the survival and prognostic factors of esophageal cancer treated with definitive ( chemo ) radiotherapy by applying novel radiation techniques including three-dimensional conformal radiotherapy (3DCRT) or intensity-modulated radiotherapy (IMRT). Methods Clinical data of 2762 patients with non-operated esophageal squamous cell carcinoma who underwent definitive ( chemo ) radiotherapy from 2002 to 2016 in 10 hospitals were retrospectively analyzed.The prognostic factors were also identified and analyzed. Results The median follow-up time was 60. 8 months. The 1-, 2-, 3-and 5-year overall survival (OS) of all patients was 71. 4%,48. 9%,39. 3%,and 30. 9%,respectively.The 1-,2-,3-and 5-year progression-free survival (PFS) was 59.5%,41.5%,35.2%,and 30%,respectively.The median survival was 23 months.The median time to progression was 17. 2 months.Multivariate analysis demonstrated that age, primary tumor location, clinical stage, tumor target volume, EQD2 and treatment mode were the independent prognostic factors for OS.Primary tumor location,clinical stage,tumor target volume and EQD2 were the independent prognostic factors for PFS. Conclusions In this first large-scale multi-center retrospective analysis of definitive ( chemo) radiotherapy for esophageal squamous cell carcinoma in China, the 5-year OS of patients with esophageal squamous cell carcinoma is significantly improved by 3DCRT, IMRT combined with chemotherapy drugs. However, the findings remain to be validated by prospective clinical trials with high-level medical evidence.

To systemically evaluate the efficacy and safety of Gingko Ketone Ester Dropping Pills in treating angina pectoris and co-ronary heart disease. CNKI, Wanfang, SinoMed, PubMed, Cochrane Library and EMbase databases were retrieved on computer, and the randomized clinical trial(RCT) on Gingko Ketone Ester Dropping Pills in treating angina pectoris and coronary heart disease, which were published from the database establishment to December 31, 2019, were comprehensively collected. Literature screening, data extraction and quality evaluation were conducted independently by two researchers according to inclusion and exclusion criteria. Literature methodology quality evaluation was conducted with use of the Cochrane Handbook 5.3.0(bias risk assessment tool). Meta-analysis was performed with RevMan 5.3.0 software. A total of 10 RCTs were included. The results of the Meta-analysis showed that as compared with conventional Western medicine alone, the application of Gingko Ketone Ester Dropping Pills combined with conventional Western medicine treatment further improved the total effective rate and electrocardiogram effect(RR=1.43,95%CI[1.20,1.71],P<0.000 1). There were statistically significant differences in the number of angina attacks, the duration of angina and the amount of nitroglycerin used. In terms of safety indicators, four studies reported adverse reactions in the experimental group, including facial flu-shing, tachycardia, dizziness, dyspnea, nausea and other symptoms. Based on the existing findings, in the treatment of angina pectoris and coronary heart disease, Gingko Ketone Ester Dropping Pills combined with conventional Western medicine can improve the clinical total effective rate, electrocardiogram effect, number of angina attacks, duration of angina and the amount of nitroglycerin used. However, in the included studies, due to some methodological quality problems which would impact the reliability of literature results more high-quality randomized controlled trials are still needed for further verification.
