        Role of Blood Pressure Management in Stroke Prevention: A Systematic Review and Network Meta-Analysis of 93 Randomized Controlled Trials

        Xiao-Ling Zhong,Yi Dong,Wei Xu,Yu-Yuan Huang,Hui-Fu Wang,Tian-Song Zhang,Li Sun,Lan Tan,Qiang Dong,Jin-Tai Yu 대한뇌졸중학회 2021 Journal of stroke Vol.23 No.1

        Background and Purpose: The present study aimed to compare the efficacy and tolerability of different blood pressure (BP)-lowering strategies. Methods: Randomized controlled trials that compared various antihypertensive treatments and stroke outcomes were included. Eligible trials were categorized into three scenarios: single or combination antihypertensive agents against placebos; single or combination agents against other agents; and different BP-lowering targets. The primary efficacy outcome was the risk reduction pertaining to strokes. The tolerability outcome was the withdrawal of drugs, owing to drug-related side effects (PROSPERO registration number CRD42018118454 [20/12/2018]). Results: The present study included 93 trials (average follow-up duration, 3.3 years). In the pairwise analysis, angiotensin-converting enzyme inhibitors (ACEis) and beta-blockers (BBs) were inferior to calcium channel blockers (CCBs) (odds ratio [OR], 1.123; 95% confidence interval [CI], 1.008 to 1.252) (OR, 1.261; 95% CI, 1.116 to 1.425) for stroke prevention, BB was inferior to angiotensin II receptor blockers (ARB) (OR, 1.361; 95% CI, 1.142 to 1.622), and diuretics were superior to ACEi (OR, 0.871; 95% CI, 0.771 to 0.984). The combination of ACEi+CCB was superior to ACEi+diuretic (OR, 0.892; 95% CI, 0.823 to 0.966). The network meta-analysis confirmed that diuretics were superior to BB (OR, 1.34; 95% CI, 1.11 to 1.58), ACEi+diuretic (OR, 1.47; 95% CI, 1.02 to 2.08), BB+CCB (OR, 2.05; 95% CI, 1.05 to 3.79), and renin inhibitors (OR, 1.87; 95% CI, 1.25 to 2.75) for stroke prevention. Regarding the tolerability profile, the pairwise analysis revealed that ACEi was inferior to CCB and less tolerable, compared to the other treatments. Conclusions: Monotherapy using diuretics, CCB, or ARB, and their combinations could be employed as first-line treatments for stroke prevention in terms of efficacy and tolerability.

        Pokemon Inhibits Transforming Growth Factor β-Smad4-Related Cell Proliferation Arrest in Breast Cancer through Specificity Protein 1

        Ling Chen,Jing Zhong,Jiang-Hua Liu,Duan-Fang Liao,Ying-Ying Shen,Xiao-Lin Zhong,Xiao Xiao,Wen-Jun Ding,Xiu-Da Peng,Wei Xiong,Xu-Yu Zu 한국유방암학회 2019 Journal of breast cancer Vol.22 No.1

        Purpose: Pokemon, also known as ZBTB7A, belongs to the POZ and Krüppel (POK) family of transcription repressors and is implicated in tumor progression as a key proto-oncogene. This present study aimed at determining the mechanism by which Pokemon inhibits transforming growth factor β (TGFβ)-Smad4 pathway-dependent proliferation arrest of breast cancer cells via specificity protein 1 (SP1). Methods: Over-expressing plasmid or small interfering RNA (siRNA) transfection was used to regulate Pokemon levels. The EdU incorporation assay, MTS assay, and clone formation were used to identify the inhibitory effect of Pokemon siRNA on cell proliferation. Quantitative real-time polymerase chain reaction assay confirmed that Pokemon deletion inhibited the expression of proliferation-associated genes. The dual-luciferase reporter assay, electrophoretic mobility shift assay, and co-immunoprecipitation assay were used to analyze binding between Pokemon, Smad4, and SP1. Results: Pokemon deletion induced proliferation arrest of breast cancer cells and inhibited the expression of proliferation-associated genes, especially Smad4. Pokemon bound with SP1 to interdict Smad4 promoter activity. Information on clinical samples was obtained from The Cancer Genome Atlas data, in which the Pokemon mRNA levels showed a negative correlation with Smad4 levels in different subtypes of breast cancer in two independent datasets. Conclusion: We demonstrated that Pokemon binds to SP1 to down-regulate Smad4 expression, thereby promoting proliferation of breast cancer cells. This suggests that Pokemon is a potential TGFβ-signaling participant in breast cancer progression.

        Synthesis and Electrochemical Properties of LiV3O8/PAn Composite as a Cathode Material for Lithium Secondary Batteries

        Ling-Ling Xie,Xiao-Yu Cao,Li-Xu Zhang,Zhong-Xu Dai,Ling-Bo Qu 대한금속·재료학회 2013 ELECTRONIC MATERIALS LETTERS Vol.9 No.2

        A LiV3O8/polyaniline (PAn) composite was prepared by the in-situ polymerization method assisted by sodium dodecyl sulfate and ammonium persulfate. The as-prepared powders were investigated by XRD, SEM, and galvanostatic discharge/charge analysis. It was found that the introduction of PAn to LiV3O8 can effectively buffer the mechanical stress and restrain the number of phase changes of composite material during the electrochemical cycling. Compared with pristine LiV3O8, LiV3O8/PAn composite maintains a reversible capacity of 212.1 mAh g−1 at the current density of 30 mA g−1 after 50 cycles, approximately 22.6%, much higher than the former.

        Differential Impacts on Bacterial Composition and Abundance in Rhizosphere Compartments between Al-Tolerant and Al-Sensitive Soybean Genotypes in Acidic Soil

        Wen Zhong-Ling,Yang Min-Kai,Fazal Aliya,Liao Yong-Hui,Cheng Lin-Run,Hua Xiao-Mei,Hu Dong-Qing,Shi Ji-Sen,Yang Rong-Wu,Lu Gui-Hua,Qi Jin-Liang,Zhi Hong,Qian Qiu-Ping,Yang Yong-Hua 한국미생물·생명공학회 2020 Journal of microbiology and biotechnology Vol.30 No.8

        In this study, two soybean genotypes, i.e., aluminum-tolerant Baxi 10 (BX10) and aluminumsensitive Bendi 2 (BD2), were used as plant materials and acidic red soil was used as growth medium. The soil layers from the inside to the outside of the root are: rhizospheric soil after washing (WRH), rhizospheric soil after brushing (BRH) and rhizospheric soil at two sides (SRH), respectively. The rhizosphere bacterial communities were analyzed by high-throughput sequencing of V4 hypervariable regions of 16S rRNA gene amplicons via Illumina MiSeq. The results of alpha diversity analysis showed that the BRH and SRH of BX10 were significantly lower in community richness than that of BD2, while the WRH exhibited no significant difference between BX10 and BD2. Among the three sampling compartments of the same soybean genotype, WRH had the lowest community richness and diversity while showing the highest coverage. Beta diversity analysis results displayed no significant difference for any compartment between the two genotypes, or among the three different sampling compartments for any same soybean genotype. However, the relative abundance of major bacterial taxa, specifically nitrogen-fixing and/or aluminum-tolerant bacteria, was significantly different in the compartments of the BRH and/or SRH at phylum and genus levels, indicating genotype-dependent variations in rhizosphere bacterial communities. Strikingly, as compared with BRH and SRH, the WRH within the same genotype (BX10 or BD2) always had an enrichment effect on rhizosphere bacteria associated with nitrogen fixation

      • Progress and Challenges in Chemotherapy for Loco-Regionally Advanced Nasopharyngeal Carcinoma

        Liang, Zhong-Guo,Chen, Ze-Tan,Li, Ling,Qu, Song,Zhu, Xiao-Dong Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.12

        Incidence rates of nasopharyngeal carcinoma are high in Indonesia, Singapore and South-Eastern China. Chemoradiotherapy has been the standard regimen for locally advanced nasopharyngeal carcinoma according to guidelines from the National Comprehensive Cancer Network. Recently, advances in the management of nasopharyngeal carcinoma have transferred into better treatment outcomes. Most phase III clinical trials support the addition of concurrent chemotherapy to radiotherapy for the initial treatment of these patients. Studies evaluating effects and toxicity of concurrent chemotherapy with different regimens have been reported. However, the status of adding adjuvant chemotherapy or induction chemotherapy remains controversial. Recent studies have shown that adjuvant chemotherapy with two or three cycles may improve survival for nasopharyngeal carcinoma with stage N2-3 disease or with persistently detectable plasma EBV DNA after radiotherapy. This review examines the pertinent issues and latest studies concerning the management of loco-regionally advanced NPC, regarding concurrent chemotherapy, adjuvant chemotherapy, and induction chemotherapy in decades.

        Mean-value first-order saddlepoint approximation based collaborative optimization for multidisciplinary problems under aleatory uncertainty

        Debiao Meng,Hong-Zhong Huang,Zhonglai Wang,Ning-Cong Xiao,Xiao-Ling Zhang 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.10

        Reliability-based multidisciplinary design optimization (RBMDO) has received increasing attention in engineering design for achievinghigh reliability and safety in complex and coupling systems (e.g., multidisciplinary systems). Mean-value first-order saddlepoint approximation(MVFOSA) is introduced in this paper and is combined with the collaborative optimization (CO) method for reliabilityanalysis under aleatory uncertainty in RBMDO. Similar to the mean-value first-order second moment (MVFOSM) method, MVFOSAapproximated the performance function with the first-order Taylor expansion at the mean values of random variables. MVFOSA usessaddlepoint approximation rather than the first two moments of the random variables to estimate the probability density and cumulativedistribution functions. MVFOSA-based CO (MVFOSA-CO) is also formulated and proposed. Two examples are provided to show theaccuracy and efficiency of the MVFOSA-CO method.

      • Clinical Evaluation of Tumor Markers for Diagnosis in Patients with Non-small Cell Lung Cancer in China

        Ma, Li,Xie, Xiao-Wei,Wang, Hai-Yan,Ma, Ling-Yun,Wen, Zhong-Guang Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.12

        Background: To evaluate the value of combined detection of serum carcinoembryonic antigen (CEA), cytokeratin 19 fragment (CYFRA21-1), and carbohydrateantigen 125 (CA125) for the clinical diagnosis of nonsmall cell lung cancer (NSCLC). Materials and Methods: Serum CEA, CYFRA21-1 and CA125 were assessed in 140 patients with NSCLC, 90 patients with benign lung disease and 90 normal control subjects, and differences of expression were compared in each group, and joint effects of these tumor markers in the diagnosis of NSCLC were analyzed. Results: Serum CEA, CYFRA21-1 and CA125 in patients with NSCLC were significantly higher than those with benign lung disease and normal controls (P<0.05). The sensitivity of CEA, CYFRA21-1 and CA125 were 49.45%, 59.67%, and 44.87% respectively. As expected, combinations of these tumor markers improved their sensitivity for NSCLC. The combined detection of CEA + CYFRA21-1 was the most cost-effective combination which had higher sensitivity and specificity in NSCLC. Elevation of serum CEA and CYFRA21-1 was significantly associated with pathological types (P<0.05) and elevation of serum CEA, CYFRA21-1 and CA125 was significantly associated with TNM staging (P<0.05). Conclusions: Single measurement of CEA, CYFRA21-1 and CA125 is of diagnostic value in the diagnosis of lung cancer, and a joint detection of these three tumor markers, could greatly improve the sensitivity of diagnosis on NSCLC. Combined detection of CEA + CYFRA21-1 proved to be the most economic and practical strategy in diagnosis of NSCLC, which can be used to screen the high-risk group.

      • Tests and mechanics model for concrete-filled SHS stub columns, columns and beam-columns

        Lin-Hai Han,Xiao-Ling Zhao,Zhong Tao 국제구조공학회 2001 Steel and Composite Structures, An International J Vol.1 No.1

        A series of tests on concrete-filled SHS (Square Hollow Section) stub columns (twenty), columns (eight) and beam-columns (twenty one) were carried out. The main parameters varied in the tests are (1) Confinement factor (x ) from 1.08 to 5.64, (2) concrete compression strength from 10.7MPa to 36.6MPa, (3) tube width to thickness ratio from 20.5 to 36.5. (4) load eccentricity (e) from 15 mm to 80 mm and (5) column slenderness (l) from 45 to 75. A mechanics model is developed in this paper for concrete-filled SHS stub columns, columns and beam-columns. A unified theory is described where a confinement factor (x ) is introduced to describe the composite action between the steel tube and filled concrete. The predicted load versus axial strain relationship is in good agreement with stub column test results. Simplified models are derived for section capacities and modulus in different stages of the composite sections. The predicted beam-column strength is compared with that of 331 beam-column tests with a wide range of parameters. A good agreement is obtained. The predicted load versus midspan deflection relationship for beam-columns is in good agreement with test results. A simplified model is developed for calculating the member capacity of concrete-filled SHS columns. Comparisons are made with predicted columns strengths using the existing codes such as LRFD (AISC 1994), AIJ (1997), and EC4 (1996). Simplified interaction curves are derived for concrete-filled beam-columns.

        Reliability-based design optimization for box-booms considering strength degradation and random total working time

        Zhonglai Wang,Hong-Zhong Huang,Xiao-Ling Zhang,Yanfeng Li 대한기계학회 2012 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.26 No.7

        Box-booms are widely used in some cranes. The strength of box-booms would continuously deteriorate with the use of time. In this paper, gamma process is employed to describe strength degradation when dealing with the overall stability of the box-boom. Furthermore,the total working time is not deterministic but random because of the random arrivals of tasks and the random working time of every task. By accounting for strength degradation and the random total working time, a time-dependent reliability-based design optimization (RBDO) model for the box-boom is proposed. An engineering case is used to illustrate the proposed model.
