1Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears.Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG 2021Science China(Information Sciences)2021,64,1:122

32018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
4Massive individual orbital angular momentum channels for multiplexing enabled by Dammann gratings显示文摘Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.Orbital angular momentum(OAM)in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems,with OAM beams acting as information carriers for OAM division multiplexing(OAM-DM).We demonstrate independent collinear OAM channel generation,transmission and simultaneous detection using Dammann optical vortex gratings(DOVGs).We achieve 80/160 Tbit s^(-1) capacity with uniform power distributions along all channels,with 1600 individually modulated quadrature phase-shift keying(QPSK)/16-QAM data channels multiplexed by 10 OAM states,80 wavelengths and two polarizations.DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s^(-1) level.Ting Lei Meng Zhang Yuru Li Ping Jia Gordon Ning Liu Xiaogeng Xu Zhaohui Li Changjun Min Jiao Lin Changyuan Yu Hanben Niu Xiaocong Yuan 2015Light(Science & Applications)2015,4,1:47
5Ultrasonography guided percutaneous radiofrequency ablation for hepatic cavernous hemangioma显示文摘AIM: Hepatic cavernous hemangioma (HCH) is the mostcommon benign tumor of the liver and its management isstill controversial. Recent successin situ radiofrequencyablation of hepatic malignancies has led us to consider usingthis technique in patients with HCH. This study was to assessthe efficacy, safety, and complications of percutaneousradiofrequency ablation (PRFA) under ultrasonographyguidance in patients with HCH.METHODS: Twelve patients (four men and eight women,age ranged 33-56 years, mean age was 41.7 years) with 15hepatic cavernous hemangiomas (2.5 cm to 9.5 cm) weretreated using the RF-2000 generator and 10-needle LeVeenelectrode percutaneously guided by B-ultrasound. Lesionslarger than 3 cm were treated by multiple overlappingablations that encompass the entire lesion as well as a rimof normal liver tissue (approximately 0.5 cm).RESULTS: All the patients who received PRFA therapy hadno severe pain, bleeding or bile leakage during and afterthe procedures. Nine to 34 months′ follow-up (mean, 21months) by ultrasound and/or spiral CT scan demonstratedthat the ablated lesions in this group were shrunk remarkably,and the shrunken range was 38-79 % (mean, 67 % per 21months). The contrast enhancement was disappeared withinthe tumor or at its periphery in all cases on spiral CT scansobtained 3 to 6 months after treatment.CONCLUSION: The results of this study suggest that PRFAtherapy is a mini-invasive, simple, safe, and effective methodfor the treatment of selected patients with HCH.Yan Cui Li-Yan Zhou Man-Ku Dong Ping Wang Min Ji Xiao-Ou Li Chang-Wei Chen Zi-Pei Liu Yong-Jie Xu Hong-Wen Zhang Department of Hepatobiliary Surgery,Beijing 306 Hospital,Chaoyang District,Beijing 100101,China 2003World Journal of Gastroenterology2003,9,9:43
6Relationship between phenotypes of cell-function differentiation and pathobiological behavior of gastric carcinomas显示文摘AIM To reveal the correlation between thefunctional differentiation phenotypes of gastriccarcinoma cells and the invasion and metastasisby a new way of cell-function classification.METHODS Surgically resected specimens of361 gastric carcinomas (GC) were investigatedwith enzyme-, mucin-, and tumor-related markerimmunohistochemist ry. According to thedirection of cell-function differentiation,stomach carcinomas were divided into fivefunctionally differentiated types.iation type (AFDT): there were 82 (22.7%)patients including 76 (92.7%) aged 45 years.Sixty-nine (84.1%) cases belonged to theintestinal type. Thirty-eight (46.3%) expressedCD44v6 and 9 (13.6%) of 66 male patientsdeveloped liver metastasis. The 5-year survivalrate of patients in this group (58.5%) was higherMucin secreting function differentiation type(MSFDT): 54 (15%) cases. Fifty-three (98.1%)tumors had penetrated the serosa, 12 (22.2%)expressed ER and 22 (40.7%) expressedCD44v6. The postoperative 5-year survival ratefunction differentiation type (AMPFDT): therewere 180 (49.9%) cases, including 31 (17.2%)aged yanger than 45 years. The tumor was morecommon in women (62, 34.4%,) and expressedmore frequently estrogen receptors (ER) ( 129,81.7%) than other types (P<0.01). Ovarymetastasis was found in 12 (19.4%) out of 62female subjects. The patients with this type GChad the lowest 5-year survival rate (24.7%)differentiation type (SFDT): 13 (3.6%) cases.Nine (69.2%) tumors of this type derived fromAPUD system, the other 4 (30.7%) were ofdifferent histological differentiation. Sixty percent of the patients survived at least five years.(8.9%) cases. Nineteen (59.4%) cases hadlymph node metastases but no one with liver orovary metastasis. The 5-year survival rate was28.1%.CONCLUSION This new cell-functionclassification of GC is helpful in indicating thecharacteristics of invasion and metastasis of GCwith different cell-function differentiationphenotypes. Further study is needed to disclosethe correlation between the cell-functionaldifferentiation phenotypes and the relevantgenotypes and the biological behavior of gastriccarcinoma.Yan Xin Xiao Ling Li Yan Ping Wang Su Min Zhang Hua Chuan Zheng Dong Ying Wu Yin Chang Zhang The Fourth Laboratory of Cancer Institute, China Medical University, Shenyang 110001, Liaoning Province, China 2001World Journal of Gastroenterology2001,7,1:38
7Prevalence and evolution of drug resistance HIV-1 variants in Henan, China显示文摘To understand the prevalence and evolution of drug resistant HIV strains in Henan China after the implementation of free antiretroviral therapy for AIDS patients. 45 drug nave AIDS patients, 118 AIDS patients who received three months antiretroviral therapy and 124 AIDS patients who received six months antiretroviral treatment were recruited in the southern part of Henan province. Information on general condition, antiretroviral medicines, adherence and clinical syndromes were collected by face to face interview. Meanwhile, 14ml EDTA anticoagulant blood was drawn. CD4/CD8 T cell count, viral load and genotypic drug resistance were tested. The rates of clinical improvement were 55.1% and 50.8% respectively three months and six months after antiretroviral therapy. The mean CD4 cell count after antiretroviral therapy was significantly higher than in drug nave patients. The prevalence rate of drug resistant HIV strains were 13. 9%, 45.4% and 62.7% in drug nave patients, three month treatment patients and six month treatment patients, respectively. The number of resistance mutation codons and the frequency of mutations increased significantly with continued antiretroviral therapy. The mutation sites were primarily at the 103, 106 and 215 codons in the three-month treatment group and they increased to 15 codon mutations in the six-month treatment group. From this result, the evolution of drug resistant strains was inferred to begin with the high level NNRTI resistant strain, and then develop low level resistant strains to NRTIs. The HIV strains with high level resistance to NVP and low level resistance to AZT and DDI were highly prevalent because of the AZT+DDI+NVP combination therapy. These HIV strains were also cross resistant to DLV, EFV, DDC and D4T. Poor adherence to therapy was believed to be the main reason for the emergence and prevalence of drug resistant HIV strains. The prevalence of drug resistant HIV strains was increased with the continu- ation of antiretroviral therapy in the southern part of Henan province. Measures, that could promote high level adherence, provide new drugs and change ART regimens in failing patients, should be implemented as soon as possible.Jing Yun LI Han Ping LI Lin LI Hong LI Zhe WANG Kun YANG Zuo Yi BAO Dao Min ZHUANG Si Yang LIU Yong Jian LIU Hui XING Yi Ming SHAO 2005Cell Research2005,15,11:34
8Fermented soybean meal improves the growth performance, nutrient digestibility, and microbial flora in piglets显示文摘In order to increase nutritive values of soybean meal(SBM), 3 species of microbes were used to ferment SBM. Through a 3 x 3 orthogonal design and parameter measurements of soybean peptide and antinutritional factor contents in the fermented soybean meal(FSBM), it was estimated that the best microbial proportion of Bacillus subtilis, Hansenula anomala and Lactobacillus casei was 2:1:2 for SBM fermentation(P < 0.05). The further piglet feeding experiment showed that 10% FSBM substitute for SBM had no significant effect on growth performance of suckling piglets(d 7-28)(P> 0.05). However, newlyweaned piglets(d 28-38) fed 10% FSBM and different levels of plasma protein obtained higher average daily gain(ADG) and feed conversion ratio(FCR), compared with those without FSBM but with 6% plasma protein(P < 0.05). Piglets(d 38-68) fed diets supplemented with FSBM and soybean protein concentrate(SBPC) at 3.75% and 7.5% respectively increased nutrient digestibility,fecal enzyme activity and lactic acid bacteria counts, and decreased fecal Escherichia coli counts(P < 0.05), compared with the control. These data indicated that FSBM had positive effects on nutrient digestibility and fecal microflora for piglets.Lin Yuan Juan Chang Qingqiang Yin Min Lu Yuanran Di Ping Wang Zhixiang Wang Erzhu Wang Fushan Lu 2017Animal Nutrition2017,,1:31
9The abnormal expression of retinoic acid receptor-β,p53 and Ki67 protein,n normal,premalignant and malignant esophageal tissues显示文摘AIM: Esophageal cancer remains a significant healthiproblem worldwide. It is important to investigate alterationsin expression of retinoic acid receptor-β, p53 and Ki67proteins in esophageal carcinogenesis.METHODS: To find biomarkers for early identification ofesophageal cancer, we analyzed the retinoic acid receptor-j3,p53 protein and the proliferation marker Ki67 in surgicalspecimens of normal, mildly, and severely dysplastic andmalignant esophageal tissues by in situ hybridization ofRNA and immunohistochemistry.RESULTS: RAR-β was expressed in 94.3 %(33/35) of normalmucosae, 67.8 %(19/28) of the mild, 58.1% (18/31) of thesevere ieaions and 53.2 % (116/218) of tumor samples. RAR-β mRNA was expressed in 62.7 % (42/67), 55.1% (43/78) and29.2 % (7/24) of well, moderated and poorly differentiatedSSCs. The p53 and Ki67 proteins were 5.9 % (2/34) of thenormal mucosa. P53 and Ki67 stained positively in 10.7 % (3/28) and 21.4 % (6/28) of mild dysplasia, and 51.6 %(16/31)and 58. 1% (18/31) of severely dysplasia respectively.Samples from esophageal cancer showed no higher levers ofp53 and Ki67 expression than seen in severely dysplasticlesions. There was significant difference of RAR-β、 p53 andKi67 expression between normal mucosa and dysplatictissue or esophageal cancer.CONCLUSION: Loss of RAR-β expression and acctnulation ofp53 and Ki67 proteins may serve as biomarkers for earlyidentification of esophageal cancer in the high-riskpopulations.Min Xu Sheng-Zu Chen,Department of Nuclear Medcine,Cancer Hospital(Institute),Peking Union Medical College and Chinese Academy of Medical Sciences,Beijing 10002,1,China Yu-Lan Jin Jun Fu Hong Huang Ping Qu Hai-Mei Tian ZhaoYang Liu Wei Zhang,Central Laboratory for Tumor Biology,Cancer Hospital(Institute),Peking Union Medical College and Chinese Academy of Medical Sciences,Beijing 100021,China 2002World Journal of Gastroenterology2002,8,2:34
10Morphological study on colonic pathology in ulcerative colitis treated by moxibustion显示文摘AIM To observe the therapeutic effect ofmoxibustion on ulcerative colitis and itsinfluence on the colonic mucosal morphology.METHODS Forty-six patients with ulcerativecolitis were randomly divided into themoxibustion with herbal medicine underneathgroup and the western medicine group.Thirtypatients were treated with the abovemoxibustion and 16 patients with Salicylayefapyridine(SASP).The colonic mucosa of 13patients in the moxibustion group was observedby colonoscopy before and after the treatment.Mucin was also analyzed by H.E and AB-PASstaining.RESULTS Seventeen patients were clinicallycured,12 were improved and 1 unchanged in themoxibustion group.In the control group,5patients were clinically cured,7 improved and 4unchanged.Thirteen patients with active UCwere taken as the subjects for histopathologicanalysis in this study.The colonic mucosallesions were remarkably improved and thecharacteristic of the mucin also changed.Inmost sections,the chronic inflammation ofmucosa was geatly ameliorated(P<0.01).Theinflammatory cell infiltratation much decreased and neutrophils,disapeared in most sections(P<0.001).The goblet cells significantlyincreased(P<0.001);crypt paracrypt abscessor mucosal ulceration was seen(P<0.001).CONCLUSION The rate of cure of ulcerative colitis by moxibustion with herbal medicine beneath is superior to that by SASP. This sort of moxibustion can effectively improve the colonic mucosal lesions and restore the proportion of mucoprotein to near normal.Huan Gan Wu Li Bin Zhou Da Ren Shi Shi Min Liu Hui Rong Liu Bi Meng Zhang Han Ping Chen Lin Shan Zhang 2000World Journal of Gastroenterology2000,6,6:28
11Effect of probiotic treatment on cirrhotic patients with minimal hepatic encephalopathy: A meta-analysis显示文摘Background: Minimal hepatic encephalopathy(MHE) is an early and reversible form of hepatic encephalopathy. The documentations on the treatment with probiotics are inconsistent. The present meta-analysis was to verify the role of probiotics in the treatment of cirrhotic patients with MHE.Data sources: Seven electronic databases were searched for relevant randomized controlled trials(RCTs)published until July 2015. The effects of probiotics on serum ammonia, endotoxin, and MHE were evaluated.Results: A total of 14 RCTs(combined n = 1132) were included in the meta-analysis. When probiotics were compared to placebo or no treatment, probiotics were more likely to reduce values in the number connection test(NCT; week 4: MD =-30.25, 95% CI:-49.85 to-10.66), improve MHE(week 4: OR = 0.18,95% CI: 0.07 to 0.47; week 12: OR = 0.15, 95% CI: 0.07 to 0.32), and prevent overt HE progression(week4: OR = 0.22, 95% CI: 0.07 to 0.67) in patients with liver cirrhosis. When probiotics was compared to lactulose, probiotics tended to reduce serum ammonia levels(week 4: MD =-0.33 μmol/L, 95% CI:-5.39 to 4.74; week 8: MD = 6.22 μmol/L, 95% CI:-24.04 to 36.48), decrease NCT(week 8: MD = 3.93, 95% CI:-0.72 to 8.58), improve MHE(week 4: OR = 0.93, 95% CI: 0.45 to 1.91; week 12: OR = 0.73, 95% CI: 0.35 to 1.51) and prevent the development of overt HE(week 4: OR = 0.96, 95% CI: 0.17 to 5.44; week 12:OR = 2.7, 95% CI: 0.50 to 14.64) in patients with liver cirrhosis. However, lactulose appears to be more effective in reducing NCT values as compared to probiotics(week 4: MD = 6.7, 95% CI: 0.58 to 12.82).Conclusion: Probiotics can decrease serum ammonia and endotoxin levels, improve MHE, and prevent overt HE development in patients with liver cirrhosis.Qing Cao Cheng-Bo Yu Shi-Gui Yang Hong-Cui Cao Ping Chen Min Deng Lan-Juan Li 2018Hepatobiliary & Pancreatic Diseases International2018,17,1:25
12Comparison of the Δ^(12) fatty acid desaturase gene between high-oleic and normal-oleic peanut genotypes显示文摘Δ12 fatty acid desaturase gene has been targeted as a logical candidate controlling the high oleate trait in peanut seeds.By RT-PCR method,the full-length cDNAs of Δ12 fatty acid desaturase gene were isolated from peanut(Arachis hypogaea L.) genotypes with normal and high ratio of oleic to linoleic acid,which were designated AhFAD2B and AhFAD2B',respectively.Sequence alignment of their coding regions revealed that an extra A was inserted at the position +442 bp of AhFAD2B' sequence of high oleic acid genotypes,which resulted in the shift of open reading frame and a truncated protein AhFAD2B',with the loss of one histidine box involved in metal ion complex required for the reduction of oxygen.Analysis of transcript level showed that the expression of Δ12 fatty acid desaturase gene in high oleic acid genotype was slightly lower than that in normal genotype.The enzyme activity experiment of yeast(Saccharomyces cerevisiae) cell transformed with AhFAD2B or AhFAD2B' proved that only AhFAD2B gene product showed significant Δ12 fatty acid desaturase activity,but AhFAD2B' gene product did not.These results suggested that the change of AhFAD2B' gene sequence resulted in lower activity or deactivation of Δ12 fatty acid desaturase in high oleic acid genotype.ShanlinYu Lijuan Pan Qingli Yang Ping Min Zengkai Ren Hongsheng Zhang 2008Journal of Genetics and Genomics2008,35,11:23
13Charlson comorbidity index helps predict the risk of mortality for patients with type 2 diabetic nephropathy显示文摘研究目的:探讨Charlson合并症指数(CCI)对2型糖尿病肾病死亡率的预测作用。研究方法:建立2型糖尿病肾病研究队列,根据CCI评分将患者合并症的严重程度分为三度:轻度(CCI1–2分)、中度(CCI 3–4分)、重度(CCI≥5分)。将影响死亡率的因素及按CCI分层后的组间差异指标进行Logistic回归分析及方差分析(ANOVA)。Kaplan-Meier生存曲线分析CCI指数对生存时间及死亡率的影响。重要结论:533例2型糖尿病肾病患者纳入研究。所有患者的CCI评分均大于1,44.7%(238/533)的患者死亡。患者的死亡率随CCI评分增加而增加,CCI 1–2分患者的死亡率为21.0%(50/238),CCI 3–4分患者的死亡率为56.7%(135/238),CCI≥5分患者的死亡率为22.3%(53/238)。Logistic回归分析显示CCI评分、血红蛋白和血浆白蛋白水平是患者死亡率的预测因子(P<0.05)。方差分析结果显示,与CCI评分相对较低的患者相比,CCI评分越高的患者其血红蛋白水平较低,而血清肌酐较高,死亡率也更高。Kaplan-Meier生存曲线显示CCI评分越高的患者生存时间越短。CCI评分是一种简单易行且实用的评估疾病合并症的方法,可用于预测2型糖尿病肾病患者的死亡率。关注2型糖尿病肾病患者的合并症将有利于早期、有效治疗及改善预后。You-qun HUANG Rong GOU Yong-shu DIAO Qing-hua YIN Wen-xing FAN Ya-ping LIANG Yi CHEN Min WU Li ZANG Ling LI Jing ZANG Lu CHENG Ping FU Fang LIU 2014Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2014,15,1:23
14Association between Vitamin D Insufficiency and the Risk for Gestational Diabetes Mellitus in Pregnant Chinese Women显示文摘Objective To investigate the association between vitamin D deficiency and risk of gestational diabetes mellitus(GDM) in pregnant Chinese women.Methods A nested case-control study was conducted.Clinical and biochemical data were analyzed for 200 subjects with GDM and 200 subjects with normal glucose tolerance(NGT).Results The median(interquartile range) serum 25-hydroxyvitamin D(25OHD) levels were 22.39(17.67,29.38) and 25.86(19.09,34.88) nmol/L in the GDM and NGT groups,respectively.Rates of 25OHD deficiency or insufficiency were significantly higher in the GDM group than in the NGT group.Subjects with 25OHD levels <25 nmol/L had a 1.8-fold higher risk of GDM compared with subjects with higher vitamin D levels.In the GDM group,serum 25OHD was independently associated with HbA1c and insulin resistance after adjusting for confounding factors.In the NGT group,serum 25OHD was independently associated with fasting plasma glucose and systolic blood pressure after adjusting for maternal age and other confounding factors.Conclusion 25OHD insufficiency is very common in Chinese women.Low 25OHD status may be associated with insulin resistance and act as a risk factor for GDM.WANG Ou NIE Min HU Ying Ying ZHANG Kui LI Wei PING Fan LIU Jun Tao CHEN Li Meng XING Xiao Ping 2012Biomedical and Environmental Sciences2012,25,4:21

16Anti-inflammatory and anti-thrombogenic effects of atorvastatin in acute ischemic stroke显示文摘Atorvastatin decreases inflammation and thrombogenesis in patients with carotid artery plaque. Atorvastatin is administered to lower lipid levels, but its anti-inflammatory and anti-thrombogenic effects remain unclear. Eighty-nine patients from northeastern China with acute ischemic stroke caused by large-artery atherosclerosis were randomly divided into the study and control groups. All patients received routine treatment, including antiplatelet therapy, circulatory support, and symp-tomatic treatment. The study group (n=43) also received daily atorvastatin 20 mg/d, and the control group (n=46) received daily placebo pills containing glucose. After 4 weeks, the levels of C-reactive protein, fibrinogen, and D-dimer were significantly lower in the study group than in the control group. Decreases in the levels of C-reactive protein, fibrinogen, and D-dimer were not associated with de-creases in the levels of triacylglycerol and low-density lipoprotein cholesterol. These results suggest that atorvastatin reduces inflammation and thrombogenesis independent of its lipid-lowering effects in patients with acute ischemic stroke caused by large-artery atherosclerosis.Lianqiu Min Shuai Shao Xiaoning Wu Lin Cong Ping Liu Haiping Zhao Yumin Luo 2013Neural Regeneration Research2013,8,23:19

19Breast non-mass-like lesions on contrast-enhanced ultrasonography: Feature analysis, breast image reporting and data system classification assessment显示文摘BACKGROUND Breast non-mass-like lesions(NMLs)account for 9.2%of all breast lesions.The specificity of the ultrasound diagnosis of NMLs is low,and it cannot be objectively classified according to the 5th Edition of the Breast Imaging Reporting and Data System(BI-RADS).Contrast-enhanced ultrasound(CEUS)can help to differentiate and classify breast lesions but there are few studies on NMLs alone.AIM To analyze the features of benign and malignant breast NMLs in grayscale ultrasonography(US),color Doppler flow imaging(CDFI)and CEUS,and to explore the efficacy of the combined diagnosis of NMLs and the effect of CEUS on the BI-RADS classification of NMLs.METHODS A total of 51 breast NMLs verified by pathology were analyzed in our hospital from January 2017 to April 2019.All lesions were examined by US,CDFI and CEUS,and their features from those examinations were analyzed.With pathology as the gold standard,binary logic regression was used to analyze the independent risk factors for malignant breast NMLs,and a regression equation was established to calculate the efficiency of combined diagnosis.Based on the regression equation,the combined diagnostic efficiency of US combined with CEUS(US+CEUS)was determined.The initial BI-RADS-US classification of NMLs was adjusted according to the independent risk factors identified by CEUS,and the diagnostic efficiency of CEUS combined with BI-RADS(CEUS+BI-RADS)was calculated based on the results.ROC curves were drawn to compare the diagnostic values of the three methods,including US,US+CEUS,and CEUS+BI-RADS,for benign and malignant NMLs.RESULTS Microcalcification,enhancement time,enhancement intensity,lesion scope,and peripheral blood vessels were significantly different between benign and malignant NMLs.Among these features,microcalcification,higher enhancement,and lesion scope were identified as independent risk factors for malignant breast NMLs.When US,US+CEUS,and CEUS+BI-RADS were used to identify the benign and malignant breast NMLs,their sensitivity rates were 82.6%,91.3%,and 87.0%,respectively;their specificity rates were 71.4%,89.2%,and 92.9%,respectively;their positive predictive values were 70.4%,87.5%,and 90.9%,respectively;their negative predictive values were 83.3%,92.6%,and 89.7%,respectively;their accuracy rates were 76.5%,90.2%,and 90.2%,respectively;and their corresponding areas under ROC curves were 0.752,0.877 and 0.903,respectively.Z tests showed that the area under the ROC curve of US was statistically smaller than that of US+CEUS and CEUS+BI-RADS,and there was no statistical difference between US+CEUS and CEUS+BI-RADS.CONCLUSION US combined with CEUS can improve diagnostic efficiency for NMLs.The adjustment of the BI-RADS classification according to the features of contrastenhanced US of NMLs enables the diagnostic results to be simple and intuitive,facilitates the management of NMLs,and effectively reduces the incidence of unnecessary biopsy.Ping Xu Min Yang Yong Liu Yan-Ping Li Hong Zhang Guang-Rui Shao 2020World Journal of Clinical Cases2020,8,4:18
20ABO sequence analysis in an AB type with anti-B patient显示文摘ABO blood group system is the first to be discovered and the most clinically important in transfusion medicine.1The ABO gene encodes a glycosyltransferase which synthesize the oligosaccharide epitopes.The difference between the consensus A gene (A101 allele) usually used as the reference and the consensus B gene (B101 allele) are 7 in-frame single nucleotide polymorphisms (SNPs),among which only 4 alleles cause amino acid mutations in the enzyme.When A allele was inherited from one parent and B allele was inherited from the other which produced the AB blood group,this is known as trans-AB.Cis-AB is characterized as mutant ABO alleles encoding a glycosyltransferase capable of synthesizing both A and B antigens which is very rare.Chen Qing Xiao Jianyu Wang Shuya Li Jiahuang Du Leilei Lu Le Huang Chengyin Li Min Li Ping 2014Chinese Medical Journal2014,,5:17
