| 1 | 2018 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 | 2018 | Science Bulletin2018,63,23: | 54 |
| 2 | Service-aware 6G:An intelligent and open network based on the convergence of communication,computing and caching显示文摘With the proliferation of the Internet of Things(IoT),various services are emerging with totally different features and requirements,which cannot be supported by the current fifth generation of mobile cellular networks(5G).The future sixth generation of mobile cellular networks(6G)is expected to have the capability to support new and unknown services with changing requirements.Hence,in addition to enhancing its capability by 10–100 times compared with 5G,6G should also be intelligent and open to adapt to the ever-changing services in the IoT,which requires a convergence of Communication,Computing and Caching(3C).Based on the analysis of the requirements of new services for 6G,this paper identifies key enabling technologies for an intelligent and open 6G network,all featured with 3C convergence.These technologies cover fundamental and emerging topics,including 3C-based spectrum management,radio channel construction,delay-aware transmission,wireless distributed computing,and network self-evolution.From the detailed analysis of these 3C-based technologies presented in this paper,we can see that although they are promising to enable an intelligent and open 6G,more efforts are needed to realize the expected 6G network. | Yiqing Zhou Ling Liu Lu Wang Ning Hui Xinyu Cui Jie Wu Yan Peng Yanli Qi Chengwen Xing | 2020 | Digital Communications and Networks2020,6,3: | 57 |
| 3 | Prevalence 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 | 2005 | Cell Research2005,15,11: | 34 |

| 11 | Effect of wide-narrow row arrangement in mechanical pot-seedling transplanting and plant density on yield formation and grain quality of japonica rice显示文摘Mechanical pot-seedling transplanting is an innovatively developed transplanting method that has the potential to replace mechanical carpet-seedling transplanting. However, the initial pot-seedling transplanting machine lacked optimized density spacing and limited yield potential for japonica rice. Therefore, ascertaining the optimized density by wide-narrow rows and the appropriate transplanting method for yield formation and grain quality of japonica rice is of great importance for high-quality rice production. Field experiments were conducted using two japonica rice cultivars Nanjing 9108 and Nanjing 5055 under three transplanting methods in 2016 and 2017: mechanical pot-seedling transplanting with wide-narrow row(K, average row spacing of 30 cm);equidistant row(D, 33 cm×12 cm);and mechanical carpet-seedling transplanting(T, 30 cm×12.4 cm). In addition, five different density treatments were set in K(K1–K5, from 18.62×10~4 to 28.49×10~4 hills ha^(–1)). The results showed that the highest yield was produced by a planting density of 26.88×104 hills ha^(–1) in mechanical pot-seedling transplanting with wide-narrow row with a greater number of total spikelets that resulted from significantly more panicles per area and slightly more grain number per panicle, as compared with equidistant row, and yield among density in wide-narrow row showed a parabolic trend. Compared with mechanical carpet-seedling transplanting, the treatment of the highest yield increased yield significantly, which was mainly attributed to the larger sink size with improved filled-grain percentage and grain weight, higher harvest index, and increased total dry matter accumulation, especially the larger amount accumulated from heading stage to maturity stage. With the density in wide-narrow row decreasing, processing quality, appearance quality, and nutrition quality were all improved, whereas amylose content and the taste value were decreased. Compared with mechanical carpet-seedling transplanting, mechanical pot-seedling transplanting improved processing quality and nutrition quality, but decreased amylose content and deteriorated appearance quality. These results suggested that mechanical pot-seedling transplanting with wide-narrow row coupling produced a suitable planting density of 26.88×10~4 hills ha^(–1) and may be an alternative approach to improving grain yield and quality for japonica rice. | HU Qun JIANG Wei-qin QIU Shi XING Zhi-peng HU Ya-jie GUO Bao-wei LIU Guo-dong GAO Hui ZHANG Hong-cheng WEI Hai-yan | 2020 | Journal of Integrative Agriculture2020,19,5: | 19 |
| 12 | Growth-inhibiting effects of taxol on human liver cancer in vitro and in nude mice显示文摘AIM To investigate the effects of taxol onSMMC-7721 human hepatoma and itsmechanisms.METHODS In vitro cell growth was assessedby trypan blue exclusion method.Experimentalhepatoma model was established by seedingSMMC-7721 cells subcutaneously into Balb/c(nu/nu)nude mice.In vivo tumor growth wasdetermined by measurement of tumor diameterwith Vernier calipers.The syntheses of DNA,RNA and protein were analyzed by incorporationof ~3H-thymidine,~3H-uridine and ~3H-leucinerespectively.Using light and electronmicroscopes to observe the morphologicalchanges of cells including mitosis andapoptosis.RESULTS Taxol was effective against SMMC-7721 human hepatoma cell growth in the rangesof 2.5 nmol/L-10 nmol/L with mitotic arrestand apoptosis in vitro.DNA,RNA and proteinsyntheses in cells were also obviouslysuppressed by in vitro treatment of taxol for72 h.Taxol at 2.5 nmol/L reduced ~3H-thymidineuptake to about 34% of the control value(P<0.05).Increasing the dose of taxol to20 nmol/L resulted in a greater decrease in ~3H-thymidine incorporation to 60% of the controlvalue(P<0.01).At a concentration of 20 nmol/L,the ~3H-uridine and ~3H-leucine uptakeswere reduced to 52%(P<0.05)and 63%(P<0.01),respectively.In vivo,taxolsignificantly inhibited SMMC-7721 tumor growthat 10 mg/kg,i.p.,once daily for 10 d.A morethan 90% decrease in tumor volume wasobserved by day 11(P<0.01)similarly withmitotic arrest and cell apoptosis.CONCLUSION Taxol has a marked anticanceractivity in SMMC-7721 human hepatoma both invitro and in nude mice.Its mechanisms might beassociated with mitotic arrest,subsequently,apoptosis of the hepatoma cells.No obvioustoxicity was observed with in vivoadministration of taxoi. | Jin Hui Yuan Ru Ping Zhang Ru Gang Zhang Li Xia Guo Xing Wang Wang Dan Luo Yong Xie Hong Xie | 2000 | World Journal of Gastroenterology2000,6,2: | 18 |
| 13 | Pretreatment HIV drug resistance in adults initiating antiretroviral therapy in China,2017显示文摘Background:After the scale-up of antiretroviral therapy(ART)for HIV infected people,increasing numbers of patients have pretreatment drug resistance(PDR).In this study,the prevalence of PDR was evaluated in adults initiating antiretroviral therapy in China.Methods:Blood samples were obtained from 1943 patients who initiated antiretroviral therapy(ART)in 2017 from 13 provinces or cities in China.Pol sequences were used to analyze drug resistance and construct transmission networks.Logistic regression model was used to estimate the potential factors associated with PDR.Results:In total,1711 eligible patients(76.0%male;87.8%aged≥25 years)were included,of which 117(6.8%)had PDR.The highest rates of PDR were 12.2%in Liangshan Prefecture of Sichuan and 9.3 and 8.9%in Dehong and Lincang Prefecture of Yunnan.A multivariate logistic regression analysis revealed that PDR was significantly higher among intravenous drug users(adjusted Odds Ratio(aOR)=2.64,95%CI:1.57–4.44)and individuals from Liangshan,Dehong,and Lincang(aOR=2.04,95%CI:1.26–3.30).In total,754 sequences were used to generate 164 transmission networks.Five transmission networks had two or three sequences containing the same mutations,two networks contained subjects from Liangshan,and one network contained subjects from Dehong.Conclusions:Overall,the PDR prevalence was moderate,with a particularly high prevalence in areas with severe HIV epidemics.These results indicate the importance of continuous PDR monitoring in patients initiating antiretroviral therapy. | Rui-Hua Kang Shu-Jia Liang Yan-Ling Ma Shu Liang Lin Xiao Xin-Hui Zhang Hong-Yan Lu Xiao-Qin Xu Shui-Bin Luo Xiao-Guang Sun Lin Chen Jian-Mei He Guo-Hui Wu Ling-Jie Liao Hui Xing Yi-Ming Shao Yu-Hua Ruan | 2020 | Infectious Diseases of Poverty2020,9,3: | 17 |

| 15 | Surgical treatment for both-column acetabular fractures using pre-operative virtual simulation and three-dimensional printing techniques显示文摘Background:Surgical treatment of both-column acetabular fractures is challenging because of the complex acetabular fracture patterns and the curved surface of the acetabulum.Seldom study has compared the application of three-dimensional(3D)printing technology and traditional methods of contouring plates intra-operatively for the surgical treatment of both-column acetabular fractures.We presented the use of both 3D printing technology and a virtual simulation in pre-operative planning for both-column acetabular fractures.We hypothesized that 3D printing technology will assist orthopedic surgeons in shortening the surgical time and improving the clinical outcomes.Methods:Forty patients with both-column acetabular fractures were recruited in the randomized prospective case-control study from September 2013 to September 2017 for this prospective study(No.ChiCTR1900028230).We allocated the patients to two groups using block randomization(3D printing group,n=20;conventional method group,n=20).For the 3D printing group,1:1 scaled pelvic models were created using 3D printing,and the plates were pre-contoured according to the pelvic models.The plates for the conventional method group were contoured during the operation without 3D printed pelvic models.The operation time,instrumentation time,time of intra-operative fluoroscopy,blood loss,number of times the approach was performed,blood transfusion,post-operative fracture reduction quality,hip joint function,and complications were recorded and compared between the two groups.Results:The operation and instrumentation times in the 3D printing group were significantly shorter(130.8±29.2 min,t=-7.5,P<0.001 and 32.1±9.5 min,t=-6.5,P<0.001,respectively)than those in the conventional method group.The amount of blood loss and blood transfusion in the 3D printing group were significantly lower(500[400,800]mL,Mann-Whitney U=74.5,P<0.001 and 0[0,400]mL,Mann-Whitney U=59.5,P<0.001,respectively)than those in the conventional method group.The number of the approach performed in the 3D printing group was significantly smaller than that in the conventional method group(pararectus+Kocher-Langenbeck[K-L]approach rate:35%vs.85%;x2=10.4,P<0.05).The time of intra-operative fluoroscopy in the 3D printing group was significantly shorter than that in the conventional method group(4.2±1.8 vs.7.7±2.6 s;t=-5.0,P<0.001).The post-operative fracture reduction quality in the 3D printing group was significantly better than that in the conventional method group(good reduction rate:80%vs.30%;x2=10.1,P<0.05).The hip joint function(based on the Harris score 1 year after the operation)in the 3D printing group was significantly better than that in the conventional method group(excellent/good rate:75%vs.30%;χ^2=8.1,P<0.05).The complication was similar in both groups(5.0%vs.25%;χ^2=3.1,P=0.182).Conclusions:The use of a pre-operative virtual simulation and 3D printing technology is a more effective method for treating bothcolumn acetabular fractures.This method can shorten the operation and instrumentation times,reduce blood loss,blood transfusion and the time of intra-operative fluoroscopy,and improve the post-operative fracture reduction quality. | Ji-Hui Huang Hui Liao Xin-Yu Tan Wei-Rong Xing Qi Zhou Yu-Shi Zheng Hong-Yu Cao Can-Jun Zeng | 2020 | Chinese Medical Journal2020,,4: | 15 |
| 16 | Changing Proportions of HIV-1 Subtypes and Transmitted Drug Resistance Among Newly Diagnosed HIV/AIDS Individuals—China,2015 and 2018显示文摘Introduction:With the expansion of human immunodeficiency virus(HIV)antiretroviral therapy(ART),HIV drug resistance is becoming more and more serious.This study describes the changing prevalence of HIV-1 subtypes and transmitted drug resistance(TDR)among newly diagnosed individuals in China,2015 and 2018.Methods:A total of 8,980 individuals in 2015 and 2018 from 31 provincial-level administrative divisions(PLADs)were enrolled in this study.Viral RNAs were amplified and sequenced using an in-house polymerase chain reaction(PCR)protocol.The Stanford HIV Drug Resistance Database(HIVdb)was used to predict susceptibility to 12 antiretroviral drugs.Results:The prevalence of TDR was not significantly increased over time.The prevalence of TDR was 3.8%and 4.4%in 2015 and 2018,respectively(P=0.13).The prevalence of CRF55_01B increased from 2.3%in 2015 to 3.9%in 2018(P<0.001).The drug resistance prevalence of nonnucleoside reverse transcriptase inhibitors(NNRTI)increased from 2.4%in 2015 to 3.3%in 2018(P<0.01).The prevalence of E138(P<0.001),H221(P=0.03),and V179(P<0.001)mutations increased from 0.30%,0.09%,and 0.70%in 2015 to 1.10%,0.30%,and 1.70%in 2018,respectively.Conclusions:HIV drug resistance affects the effect of antiretroviral treatment,so the monitoring of HIV TDR should be strengthened to control the transmission of HIV drug resistance. | Jingjing Hao Shan Zheng Mengze Gan Aobo Dong Ruihua Kang Miaomiao Li Shuai Zhao Jing Hu Chang Song Lingjie Liao Yi Feng Yiming Shao Yuhua Ruan Hui Xing | 2021 | China CDC weekly2021,3,53: | 13 |
| 17 | Increase of TNFα-stimulated Osteoarthritic Chondrocytes Apoptosis and Decrease of Matrix Metalloproteinases 9 by NF-κB Inhibition显示文摘Objective To investigate the in vitro effect of caffeic acid phenethyl ester(CAPE),a NF-κB inhibitor,on the apoptosis of osteoarthritic(OA)chondrocytes and on the regulation of the gelatinases matrix metalloproteinase 2(MMP-2)and matrix metalloproteinase 9(MMP-9).Methods Annexin V-FITC/propidium iodide(PI)labeling and western blotting were used to observe and determine the apoptosis in TNFα-stimulated primary cultured osteoarthritic chondrocytes.Also,gelatin zymography was applied to examine MMP-2 and MMP-9 activities in supernatants.Results It was confirmed by both flow cytometry and western blotting that chondrocytes from OA patients have an apoptotic background.Use of CAPE in combination with 10 ng/mL of TNFα for 24 h facilitated the apoptosis.MMP-9 in the supernatant could be autoactivated(from proMMP-9 to active MMP-9),and the physiologic calcium concentration(2.5 mmol/L)could delay the autoactivation of MMP-9.The activities of MMP-2 and MMP-9 in the fresh supernatant increased significantly in response to stimulation by 10 ng/mL of TNFα for 24 h.The stimulatory effect of TNFα just on proMMP-9 was counteracted significantly by CAPE.Conclusion NF-κB could prevent chondrocytes apoptosis though its activation was attributed to the increase of proMMP-9 activity induced by TNFα(a pro-apoptotic factor).Therefore,therapeutic NF-κB inhibitor was a 'double-edged swords' to the apoptosis of chondrocytes and the secretion of MMP-9. | WANG Yan LI De Ling ZHANG Xin Bo DUAN Yuan Hui WU Zhi Hong HAO Dong Sheng CHEN Bao Sheng QIU Gui Xing | 2013 | Biomedical and Environmental Sciences2013,26,4: | 13 |
| 18 | Topographic differentiations of biological soil crusts and hydraulic properties in fixed sand dunes, Tengger Desert显示文摘Biological soil crusts(BSCs) play an important role in surface soil hydrology. Soils dominated with moss BSCs may have higher infiltration rates than those dominated with cyanobacteria or algal BSCs. However, it is unnown whether improved infiltration in moss BSCs is accompanied by an increase in soil hydraulic conductivity or water retention capacity. We investigated this question in the Tengger Desert, where a 43-year-old revegetation program has promoted the formation of two distinct types of BSCs along topographic positions, i.e. the moss-dominated BSCs on the interdune land and windward slopes of the fixed sand dunes, and the algal-dominated BSCs on the crest and leeward slopes. Soil water retention capacity and hydraulic conductivity were measured using an indoor evaporation method and a field infiltration method. And the results were fitted to the van Genuchten–Mualem model. Unsaturated hydraulic conductivities under greater water pressure(<–0.01 MPa) and water retention capacities in the entire pressure head range were higher for both crust types than for bare sand. However, saturated and unsaturated hydraulic conductivities in the near-saturation range(>–0.01 MPa) showed decreasing trends from bare sand to moss crusts and to algal crusts. Our data suggested that topographic differentiation of BSCs significantly affected not only soil water retention and hydraulic conductivities, but also the overall hydrology of the fixed sand dunes at a landscape scale, as seen in the reduction and spatial variability in deep soil water storage. | Zhi Shan ZHANG Yong Le CHEN Bin Xing XU Lei HUANG Hui Juan TAN Xue Jun DONG | 2015 | Journal of Arid Land2015,7,2: | 13 |
| 19 | Effect of Quercetin on Atherosclerosis Based on Expressions of ABCA1, LXR-α and PCSK9 in ApoE-/- Mice显示文摘Objective:To investigate the effect of quercetin on ATP binding cassette transporter A1(ABCA1),liver X receptor(LXR),and proprotein convertase subtilisin/kexin type 9(PCSK9)expressions in apoE-knockout(ApoE-/-)mice.Methods:The high-fat diet-induced atherosclerosis(AS)in ApoE-/-mice was established.Thirtysix mice were divided into 3 groups using random number table method:model group(n=12),quercetin group(n=12),and atorvastatin group(n=12),with C57BL/6J mice of the same strain and age as the control group(n=12).Quercetin group and atorvastatin group were administrated with quercetin and atorvastatin by oral gavage,with doses of 12.5 and 4 mg/(kg・d),respectively.Animals in the control and model groups were given an equal volume of distilled water by oral gavage once per day for a total of 12 weeks.Western blot and immunohistochemical methods were employed to determine the aortic ABCA1,LXR-a and PCSK9 protein expressi on.En zyme linked imm uno sorbent assay method was used to detect the expressi on of serum total cholesterol(TC),triglyceride(TG),high density lipoprotein-cholesterol(HDL-C),low density lipoproteincholesterol(LDL-C),tumor necrosis factor-a(TNF-a),interleukin-6(IL-6),and IL-10,combined with tissue pathological exami nation.Results:ApoE-/-mice fed with a high-fat diet had no table atherosclerosis lesions,with reduced ABCA1,LXR-a and IL-10 levels(all P<0.01),elevated PCSK9,TNF-a and IL-6 expression,and increased TC and LDL-C con tents(all P<0.01).After querceti n in terventi on,the areas of AS plaques and the expressions of PCSK9,TNF-a and IL-6 were significantly reduced(all P<0.01),while the expressions of ABCA1 and LXR-a were increased significantly(all P<0.01).Conclusion:Quercetin effectively interfered with AS development by regulating the expressions of ABCA1,LXR-a and PCSK9 in ApoE,mice. | LI Shan-shan CAO Hui SHEN Ding-zhu CHEN Chuan XING San-li DOU Fang-fang JIA Qing-ling | 2020 | Chinese Journal of Integrative Medicine2020,26,2: | 13 |
| 20 | A 12-year cohort study on the efficacy of plasmaderived hepatitis B vaccine in rural newborns显示文摘AIM To understand the anti-HBs persistenceand the long-term preventive efficacy in ruralnewborns after vaccination with plasma-derivedhepatitis B vaccine.METHODS In the time of expanded program onimmunization(EPI),the newborns werevaccinated with 10μg×3 doses of hepatitis Bvaccine and 762 newborns who were HBsAgnegative after primary immunization wereselected for cohort observation from 1986 to1998.Their serum samples were detectedqualitatively and quantitatively for hepatitis Binfecting markers,including HBsAg,anti-HBsand anti-HBc by SPRIA Kits.The annual HBsAgpositive conversion rate was counted by life-table method.RESULTS①The anti-HBs positive rate was94.44% for the babies born to HBsAg negativemothers and 84.21% for those born to HBsAgpositive mothers in the 1st year afterimmunization,and dropped to 51.31% and52.50% in the 12th year respectively.GMT valuewas dropped from 31.62 to 3.13 and 23.99 to 3.65in the 2nd to the 12th year respectively.Therewas a marked drop in GMT at the 3rd to the 5thyear,and in anti-HBs positive rate at the 9th tothe 10th year.②In the period of 12 yearsobservation,the person-year HBsAg positive conversion rates were 0.12%(5/4150.0)innewborns born to HBsAg negative mothers and0.20%(1/508.0)in those born to HBsAgpositive mothers,and none of the HBsAgpositive converted children became HBsAgchronic carriers.Compared with the baselinebefore immunization,the protective rates were97.19% and 95.32% respectively.CONCLUSION The protective efficacy ofplasma-derived hepatitis B vaccine persisted atleast 12 years,and a booster dose seems notnecessary within at least 12 years after theprimary three-doses immunization to newbornsborn to HBsAg negative mothers. | Hong Bin Liu Zong Da Meng Jing Chen Ma Chang Quan Han Ying Lin Zhang Zhan Chun Xing Yu Wei Zhang Yu Zhong Liu Hui Lin Cao | 2000 | World Journal of Gastroenterology2000,6,3: | 11 |
