| 1 | Analysis of status and countermeasures of cancer incidence and mortality in China显示文摘Cancer is the leading cause of human deaths in the world and produces serious economic burdens. On September 12, 2018, the academic journal A Cancer Journal for Clinicians published an article about the latest statistics of cancers worldwide, which provided a status report on the global burden of 36 cancers in 185 countries worldwide. Cancer has also become a serious public health problem in China and caused more and more attention of the government and people in recent years. This review analyzes the incidence, mortality and prevalent trend of cancers in China, discusses the reasons behind this status, and reviews the potential countermeasures for cancer prevention and control in China. | Chunchun Wu Mengna Li Hanbing Meng Yukun Liu Weihong Niu Yao Zhou Ran Zhao Yumei Duan Zhaoyang Zeng Xiaoling Li Guiyuan Li Wei Xiong Ming Zhou | 2019 | Science China(Life Sciences)2019，62，5： | 175 |

| 3 | Rhizospheric microbial communities are driven by Panax ginseng at different growth stages and biocontrol bacteria alleviates replanting mortality显示文摘The cultivation of Panax plants is hindered by replanting problems, which may be caused by plantdriven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased,whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages. Few microbial community, such as Luteolibacter, Cytophagaceae, Luteibacter, Sphingomonas,Sphingomonadaceae, and Zygomycota, were observed; the relative abundance of microorganisms, namely,Brevundimonas, Enterobacteriaceae, Pandoraea, Cantharellales, Dendryphion, Fusarium, and Chytridiomycota,increased in the soils of adult ginseng plants compared with those in the soils of 2-year-old seedlings. Bacillus subtilis 50-1, a microbial antagonist against the pathogenic Fusarium oxysporum, was isolated through a dual culture technique. These bacteria acted with a biocontrol efficacy of 67.8%. The ginseng death rate and Fusarium abundance decreased by 63.3% and 46.1%, respectively, after inoculation with B. subtilis 50-1. Data revealed that microecological degradation could result from ginseng-driven changes in rhizospheric microbial communities;these changes are associated with the different ages and developmental stages of ginseng plants. Biocontrol using microbial antagonists alleviated the replanting problem. | Linlin Dong Jiang Xu Lianjuan Zhang Ruiyang Cheng Guangfei Wei He Su Juan Yang Jun Qian Ran Xu Shilin Chen | 2018 | Acta Pharmaceutica Sinica B2018，8，2： | 27 |
| 4 | Programmed death-1 expression is associated with the disease status in hepatitis B virus infection显示文摘AIM: To define the potential role of programmed death-1/programmed death-ligand (PD-1/PD-L) pathway in different hepatitis B virus (HBV) infection disease status; we examined the expression of PD-1 on antigen specific CD8+ T cells in peripheral blood of patients with chronic hepatitis B (CHB) and acute exacerbation of hepatitis B (AEHB) infection. METHODS: The PD-1 level on CD8+ T lymphocytes and the number of HBV specifi c CD8+ T lymphocytes in patients and healthy controls (HCs) were analyzed by staining with pentameric peptide-human leukocyte antigen2 (HLA2) complexes combined with flow cytometry. Real-time quantitative polymerase chain reaction (PCR) was used to measure the serum HBV-DNA levels. RESULTS: The level of PD-1 expression on total CD8+ T cells in CHB patients (13.86% ± 3.38%) was significantly higher than that in AEHB patients (6.80%± 2.19%, P < 0.01) and healthy individuals (4.63% ± 1.23%, P < 0.01). Compared to AEHB patients (0.81% ± 0.73%), lower frequency of HBV-specific CD8+ T cells was detected in chronic hepatitis B patients (0.37% ± 0.43%, P < 0.05). There was an inverse correlation between the strength of HBV-specific CD8+ T-cell response and the level of PD-1 expression. Besides, there was a significant positive correlation between HBV viral load and the percentage of PD-1 expression on CD8+ T cells in CHB and AEHB subjects (R = 0.541, P < 0.01). However, PD-1 expression was not associated with disease flare-ups as indicated by alanine aminotransferase (ALT) levels (R = 0.066, P > 0.05). CONCLUSION: Our results confirm previous reports that HBV specific CD8+ T-cell response in the peripheral blood is more intense in patients with AEHB than in chronic hepatitis B with persistent viral infection. Moreover, there is a negative correlation between the level of PD-1 and the intensity of virus specific CD8+T cell response. | Plan Ye Zhi-Hong Weng Shu-Ling Zhang Jian-Ao Zhang Lei Zhao Ji-Hua Dong Sheng-Hua Jie Ran Pang Rong-Hua Wei | 2008 | World Journal of Gastroenterology2008，14，28： | 25 |
| 5 | TD-AltBOC:A new COMPASS B2 modulation显示文摘AltBOC(15,10) is the baseline of COMPASS B2 signal modulation.It is a BOC-like signal having different PN codes in the lower and the upper main split lobes,which allow one signal service per lobe.The two lobes can be received and processed separately like two BPSK(10) signals,or coherently processed to achieve better performance.Interoperability among COMPASS B2,Galileo E5 and GPS L5 is also achievable using AltBOC modulation.However,Galileo's 4-code AltBOC has drawbacks such as low efficiency and great receiver complexity.This paper presents a new modulation type named TD-AltBOC (Time Division AltBOC).The signal generation scheme and receiving method are presented,and are compared with AltBOC in the areas of power spectrum,ranging accuracy,anti-multipath performance,anti-interference performance,processing flexibility and complexity.Analysis results show TD-AltBOC has similar spectrum characteristics,interoperability,flexibility and anti-interference performance with AltBOC.When the frontend bandwidth is more than 50 MHz,TD-AltBOC can achieve better ranging accuracy and anti-multipath performance.It also has such advantages as high efficiency and low receiver complexity.TD-AltBOC could be a good solution to COMPASS B2 navigation signal. | TANG ZuPing ZHOU HongWei WEI JiaoLong YAN Tao LIU YuQi RAN YiHang ZHOU YanLing | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，6： | 20 |

| 8 | Dendrobium sonia polysaccharide regulates immunity and restores the dysbiosis of the gut microbiota of the cyclophosphamide-induced immunosuppressed mice显示文摘To recognize the potential medicinal value of the Dendrobium sonia, polysaccharide(DSP) was extracted, purified, and investigated for its immunomodulatory activity. In vitro, DSP was shown to enhance the viability(MTT assay) and phagocytosis of macrophages. In cyclophosphamide-induced immunosuppressed mice, DSP increased serum levels of TNF-α, IL-6 and IFN-γ(enzyme-linked immunosorbent assay, ELISA), and ameliorated the imbalance of the community of gut microbiota as detected by 16 S ribosomal RNA gene sequencing. These results suggest that DSP might be beneficial for patients under immunosuppressed conditions. | LIU Wei YAN Ran ZHANG Liang | 2019 | Chinese Journal of Natural Medicines2019，17，8： | 13 |
| 9 | In situ observation of austenite grain growth behavior in the simulated coarse-grained heat-affected zone of Ti-microalloyed steels显示文摘The austenite grain growth behavior in a simulated coarse-grained heat-affected zone during thermal cycling was investigated via in situ observation. Austenite grains nucleated at ferrite grain boundaries and then grew in different directions through movement of grain boundaries into the ferrite phase. Subsequently, the adjacent austenite grains impinged against each other during the α→γ transformation. After the α→γ transformation, austenite grains coarsened via the coalescence of small grains and via boundary migration between grains. The growth process of austenite grains was a continuous process during heating, isothermal holding, and cooling in simulated thermal cycling. Abundant finely dispersed nanoscale TiN particles in a steel specimen containing 0.012wt% Ti effectively retarded the grain boundary migration, which resulted in refined austenite grains. When the Ti concentration in the steel was increased, the number of TiN particles decreased and their size coarsened. The big particles were not effective in pinning the austenite grain boundary movement and resulted in coarse austenite grains. | Xiang-liang Wan Kai-ming Wu Gang Huang Ran Wei Lin Cheng | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，9： | 13 |
| 10 | Integrated metabolomic and transcriptomic analyses revealed the distribution of saponins in Panax notoginseng显示文摘Panax notoginseng is famous for its important therapeutic effects. Saponins are bioactive compounds found in different parts and developmental stages of P. notoginseng plants. Thus, it is urgently to study saponins distribution in different parts and growth ages of P. notoginseng plants. In this study,potential biomarkers were found, and their chemical characteristic differences were revealed through metabolomic analysis. High-performance liquid chromatography data indicated the higher content of saponins(i.e., Rg1, Re, Rd, and Rb1) in the underground parts than that in the aerial parts. 20(S)-Protopanaxadiol saponins were mainly distributed in the aerial parts. Additionally, the total saponin content in the 3-year-old P. notoginseng plant(188.0 mg/g) was 1.4-fold higher than that in 2-year-old plant(130.5 mg/g). The transcriptomic analysis indicated the tissue-specific transcription expression of genes, namely, PnFPS, PnSS, PnSE1, PnSE2, and PnDS, which encoded critical synthases in saponin biosyntheses. These genes showed similar expression patterns among the parts of P. notoginseng plants.The expression levels of these genes in the flowers and leaves were 5.2 fold higher than that in the roots and fibrils. These results suggested that saponins might be actively synthesized in the aerial parts and transformed to the underground parts. This study provides insights into the chemical and genetic characteristics of P. notoginseng to facilitate the synthesis of its secondary metabolites and a scientific basis for appropriate collection and rational use of this plant. | Guangfei Wei Linlin Dong Juan Yang Lianjuan Zhang Jiang Xu Feng Yang Ruiyang Cheng Ran Xu Shilin Chen | 2018 | Acta Pharmaceutica Sinica B2018，8，3： | 13 |

| 12 | Annual 30-m land use/land cover maps of China for 1980–2015 from the integration of AVHRR, MODIS and Landsat data using the BFAST algorithm显示文摘Annual land use land cover(LULC)change information at medium spatial resolution(i.e.at 30 m)is required in numerous subjects,such as biophysical modelling,land management and global change studies.Annual LULC information,however,is usually not available at continental or national scale due to reasons such as insufficient remote sensing data coverage or lack of computational capabilities.Here we integrate high temporal resolution and coarse spatial resolution satellite images(i.e.,Moderate Resolution Imaging Spectroradiometer(MODIS)and Global Inventory Modelling and Mapping Studies(GIMMS)normalized difference vegetation index(NDVI))with high spatial resolution datasets(China’s Land-Use/cover Datasets(CLUDs)derived from 30-meter Landsat TM/ETM+/OLI)to generate reliable annual nominal 30 m LULC maps for the whole of China between 1980 and 2015.We also test the performance of a statistical based change detection algorithm(Breaks for Additive Seasonal and Trend),originally designed for tracking forest change,in classifying all-type LULC change.As a result,a nominal 30 m annual land use/land cover datasets(CLUD-A)from 1980 to 2015 was developed for the whole China.The mapping results were assessed with a change sample dataset,a regional annual validation sample set and a three-year China sample set.Of the detected change years,75.61%matched the exact time of conversion within±1 year.Annual mapping results provided a detail process of urbanization,deforestation,afforestation,water and cropland dynamics over the past 36 years.The consistent characterization of land change dynamics for China can be further used in scientific research and to support land management for policy-makers. | Yidi XU Le YU Dailiang PENG Jiyao ZHAO Yuqi CHENG Xiaoxuan LIU Wei LI Ran MENG Xinliang XU Peng GONG | 2020 | Science China Earth Sciences2020，63，9： | 12 |
| 13 | Humoral immune response to circulating SARS-CoV-2 variants elicited by inactivated and RBD-subunit vaccines显示文摘SARS-CoV-2 variants could induce immune escape by mutations on the receptor-binding domain(RBD)and N-terminal domain(NTD).Here we report the humoral immune response to circulating SARS-CoV-2 variants,such as 501Y.V2(B.1.351),of the plasma and neutralizing antibodies(NAbs)elicited by CoronaVac(inactivated vaccine),ZF2001(RBD-subunit vaccine)and natural infection.Among 86 potent NAbs identified by high-throughput single-cell VDJ sequencing of peripheral blood mononuclear cells from vaccinees and convalescents,near half anti-RBD NAbs showed major neutralization reductions against the K417N/E484K/N501Y mutation combination,with E484K being the dominant cause.VH3-53/VH3-66 recurrent antibodies respond differently to RBD variants,and K417N compromises the majority of neutralizing activity through reduced polar contacts with complementarity determining regions.In contrast,the 242–244 deletion(242–244Δ)would abolish most neutralization activity of anti-NTD NAbs by interrupting the conformation of NTD antigenic supersite,indicating a much less diversity of anti-NTD NAbs than anti-RBD NAbs.Plasma of convalescents and CoronaVac vaccinees displayed comparable neutralization reductions against pseudo-and authentic 501Y.V2 variants,mainly caused by E484K/N501Y and 242–244Δ,with the effects being additive.Importantly,RBD-subunit vaccinees exhibit markedly higher tolerance to 501Y.V2 than convalescents,since the elicited anti-RBD NAbs display a high diversity and are unaffected by NTD mutations.Moreover,an extended gap between the third and second doses of ZF2001 leads to better neutralizing activity and tolerance to 501Y.V2 than the standard three-dose administration.Together,these results suggest that the deployment of RBD-vaccines,through a third-dose boost,may be ideal for combating SARS-CoV-2 variants when necessary,especially for those carrying mutations that disrupt the NTD supersite. | Yunlong Cao Ayijiang Yisimayi Yali Bai Weijin Huang Xiaofeng Li Zhiying Zhang Tianjiao Yuan Ran An Jing Wang Tianhe Xiao Shuo Du Wenping Ma Liyang Song Yongzheng Li Xiang Li Weiliang Song Jiajing Wu Shuo Liu Xuemei Li Yonghong Zhang Bin Su Xianghua Guo Yangyang Wei Chuanping Gao Nana Zhang Yifei Zhang Yang Dou Xiaoyu Xu Rui Shi Bai Lu Ronghua Jin Yingmin Ma Chengfeng Qin Youchun Wang Yingmei Feng Junyu Xiao Xiaoliang Sunney Xie | 2021 | Cell Research2021，31，7： | 12 |
| 14 | Laparoscopic vs open total gastrectomy for gastric cancer:A meta-analysis显示文摘AIM:To conduct a meta-analysis comparing laparoscopic total gastrectomy(LTG)with open total gastrectomy(OTG)for the treatment of gastric cancer.METHODS:Major databases such as Medline(PubMed),Embase,Academic Search Premier(EBSCO),Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials(CENTRAL)in The Cochrane Library were searched for studies comparing LTG and OTG from January 1994 to May 2013.Evaluated endpoints were operative,postoperative and oncological outcomes.Operative outcomes included operative time and intraoperative blood loss.Postoperative recovery included time to first fatus,time to first oral intake,hospital stay and analgesics use.Postoperative complications comprised morbidity,anastomotic leakage,anastomotic stenosis,ileus,bleeding,abdominal abscess,wound problems and mortality.Oncological outcomes included positive resection margins,number of retrieved lymph nodes,and proximal and distal resection margins.The pooled effect was calculated using either a fixed effects or a random effects model.RESULTS:Fifteen non-randomized comparative studies with 2022 patients were included(LTG-811,OTG-1211).Both groups had similar short-term oncological outcomes,analgesic use(WMD-0.09;95%CI:-2.39-2.20;P=0.94)and mortality(OR=0.74;95%CI:0.24-2.31;P=0.61).However,LTG was associated with a lower intraoperative blood loss(WMD-201.19 mL;95%CI:-296.50--105.87 mL;P<0.0001)and overall complication rate(OR=0.73;95%CI:0.57-0.92;P=0.009);fewer wound-related complications(OR=0.39;95%CI:0.21-0.72;P=0.002);a quicker recovery of gastrointestinal motility with shorter time to frst fatus(WMD-0.82;95%CI:-1.18--0.45;P<0.0001)and oral intake(WMD-1.30;95%CI:-1.84--0.75;P<0.00001);and a shorter hospital stay(WMD-3.55;95%CI:-5.13--1.96;P<0.0001),albeit with a longer operation time(WMD 48.25 min;95%CI:31.15-65.35;P<0.00001),as compared with OTG.CONCLUSION:LTG is safe and effective,and may offer some advantages over OTG in the treatment of gastric cancer. | Jun-Jie Xiong Quentin M Nunes Wei Huang Chun-Lu Tan Neng-Wen Ke Si-Ming Xie Xun Ran Hao Zhang Yong-Hua Chen Xu-Bao Liu | 2013 | World Journal of Gastroenterology2013，19，44： | 11 |
| 15 | Effect of Inoculation with Arbuscular Mycorrhizal Fungus on Nitrogen and Phosphorus Utilization in Upland Rice-Mungbean Intercropping System显示文摘The effect of arbuscular mycorrhiza fungi (AMF) on plant growth and nutrition utilization in upland rice and mungbean intercropping system was studied. A pot experiment was conducted in the greenhouse and AMF colonization rates of rice and mungbean roots, plant nutrient contents, the ability of nitrogen fixation, and nutrient contents changed in the soil were analyzed. The results were obtained as follows: the rates of AMF colonization of rice and mungbean roots were reached to 14.47 and 92.2% in intercopping system, and increased by 4.11 and 11.95% compared with that of in monocropping; the nirtrogen contents of mungbean and rice were increased by 83.72 and 64.83% in shoots, and 53.76 and 41.29% in roots, respectively, while the contents of iron in shoot and root of mungbean were increased by 223.08 and 60.19%, respectively. In the intercropping system with inoculation of AMF, the biomass of mungbean increased by 288.8%. However, the biomass of rice was not significantly changed among all treatments with or without inoculation of AMF recorded. The number and dry weight of nodules were significantly increased either when mungbean was intercropped with rice or inoculated with AMF. When compared with that of monocropping without AMF inoculation, the contents of nitrogen, phosphorus and iron in nodules of intercropping mungbean with inoculation increased by 80.14, 69.54 and 39.62%, respectively. Additionally, intercropping with AMF inoculation significantly increased soil nitrogen content, but reduced soil phosphorus content. We concluded that upland rice-mungbean intercropping system and inoculation with AMF improved the nutrient uptake, the ability of nitrogen fixation and the growth of mungbean. | XIAO Tong-jian YANG Qing-song RAN Wei XU Guo-hua SHEN Qi-rong | 2010 | Agricultural Sciences in China2010，9，4： | 11 |
| 16 | Laboratory-based flight performance of the fall armyworm,Spodoptera frugiperda显示文摘In late 2018,the fall armyworm(FAW)Spodoptera frugiperda Smith(Lepidoptera:Noctuidae)made its arrival in China and its populations have since proliferated across most of eastern Asia.While S.frugiperda exhibits a considerable dispersal capacity and engages in long-distance migration,there’s only scant information on the species’flight capability.Here,we empirically assessed S.frugiperda flight activity under varying climatic conditions using a flight mill.More specifically,under laboratory conditions,FAW exhibited superior flight performance at 20-25℃ and 60-90%relative humidity(RH).When quantifying flight performance over five consecutive nights(i.e.,10 h/night),all flight parameters initially increased and then gradually dropped and FAW adults attained a total flight distance,duration and velocity equal to 63.73 km(48.42-94.12 km)(median,quartile range),24.12 h(20.87-27.73 h)and 2.73 km h^(-1)(2.13-3.33 km h^(-1)),respectively.Our work constitutes a first comprehensive assessment of S.frugiperda flight performance and provides baseline information for future efforts to forecast spatiotemporal changes in its geographical distribution,movement patterns and invasion trajectories.Such can ultimately permit a timely and targeted deployment of area-wide pest management measures against this newly-invasive pest in China and across eastern Asia. | GE Shi-shuai HE Li-mei HE Wei YAN Ran Kris AGWYCKHUYS WU Kong-ming | 2021 | Journal of Integrative Agriculture2021，20，3： | 10 |
| 17 | Development of synthetic volatile attractant for male Ectropis obliqua moths显示文摘The tea geometrid Ectropis obliqua is one of the most serious leaf-feeding insect pests in tea(Camellia sinensis) in East Asia. Although several volatile chemicals emitted from tea plants have been reported to be attractive to E. obliqua moths, no synthetic attractants for E. obliqua moths have been developed. By measuring the behavioral responses of the moth to a series of chemicals in the lab, we found that a blend containing a ternary mixture containing(Z)-3-hexenal,(Z)-3-hexenyl hexanoate and benzyl alcohol clearly attracted to E. obliqua moths of both sex and that(Z)-3-hexenyl acetate could enhance the attractiveness of the ternary blend. Moreover, we found that the volatiles emitted from the plant-E. obliqua larva complex have the same attractiveness as: 1) the blend of volatiles containing the ternary mixture and 2) the blend containing(Z)-3-hexenyl acetate plus the ternary mixture to both male and female moths. In a field bioassay, more male moths were observed on traps that were baited with the blend containing(Z)-3-hexenyl acetate plus the ternary mixture than on control traps. Our study raises the tantalizing possibility that synthetic blends could be deployed as attractants for pests in the field. | SUN Xiao-ling LI Xi-wang XIN Zhao-jun HAN Juan-juan RAN Wei LEI Shu | 2016 | Journal of Integrative Agriculture2016，15，7： | 10 |
| 18 | Impact of hepatitis C virus genotype 3 on liver disease progression in a Chinese national cohort显示文摘Background:Hepatitis C virus(HCV)genotype 3,particularly subtype 3b,is increasing in prevalence and distribution in China.This study evaluated the prevalence,regional distribution,clinical characteristics,host factors,treatment outcomes,and disease progression of patients with HCV genotype 3 in China.Methods:A 5-year follow-up was preceded by a cross-sectional study.Treatment choices were at the discretion of treating physicians.Estimated infection time to overall-disease-progression(defined by≥1 of:newly diagnosed cirrhosis;cirrhosis at baseline,Child-Turcotte-Pugh score increased 2 points or more;progression from compensated cirrhosis to decompensated cirrhosis;hepatocellular carcinoma;liver transplantation;or death)was calculated using the Kaplan-Meier method.Cox regression analyses were conducted to evaluate the risk factors for disease progression.Results:The cross-sectional study enrolled 997 patients,including 91 with HCV genotype 3 infection.Among them,subtype 3b(57.1%)was more dominant than subtype 3a(38.5%).Five hundred and twelve patients were included into the follow-up phase.Among patients analyzed for estimated infection time to overall-disease-progression,52/304(17.1%)patients with HCV genotype 1 and 4/41(9.8%)with HCV genotype 3(4/26 with genotype 3b,0/13 with genotype 3a,and 0/2 with undefined subtype of genotype 3)experienced overall-disease-progression.Patients with HCV genotype 3 were younger than those with genotype 1(mean age:39.5±8.7 vs.46.9±13.6 years)and demonstrated more rapid disease progression(mean estimated infection time to overall-disease-progression 27.1 vs.35.6 years).Conclusions:HCV genotype 3,specifically subtype 3b,is associated with more rapid progression of liver disease.Further analysis to compare HCV subtype 3a and 3b is needed in high prevalence regions. | Nan Wu Hui-Ying Rao Wei-Bo Yang Zhi-Liang Gao Rui-Feng Yang Ran Fei Ying-Hui Gao Qian Jin Lai Wei | 2020 | Chinese Medical Journal2020，，3： | 10 |
| 19 | Geochemistry and Sr-Nd isotope characteristics of tonalites in Zêtang,Tibet:New evidence for intra-Tethyan subduction显示文摘Tonalites from the island arc rock assemblage in the Zêtang segment of the Yarlung Zangbo suture zone were analyzed for major,trace elements (including REE) and Sr-Nd isotope. The experimental data demonstrate that the tonalites have the adakite-like characteristics,including high SiO2 (58%―63%),Al2O3 (18.4%―22.4%),Sr (810×10 6―940×10 6),Sr/Y (77―106),low HREE (Y=9×10 6―11×10 6,Yb= 1×10 6―1.3×10 6),with LREE enrichment and faint Eu positive anomaly. ISr (0.70421―0.70487) is rela-tively low whereas 143Nd/144Nd (0.512896―0.512929) and εNd(t) values (+6.7―+7.3) are high. These fea-tures suggest that Zêtang tonalites were formed by the partial melting of subducted oceanic crust,with involvement of a small amount of oceanic sediments. The identification of Zêtang adakites,derived from slab melting,presents new evidence for the intra-Tethyan subduction and the previous sugges-tion about the existence of intra-oceanic island arc within Tethys. | WEI DongLiang XIA Bin ZHOU GuoQing YAN Jun WANG Ran ZHONG LiFeng | 2007 | Science China Earth Sciences2007，50，6： | 9 |
| 20 | Treatment of Herpes Zoster with Electroacupuncture plus Collateral-pricking and Cupping Therapy显示文摘Objective:To observe the clinical effect of electroacupuncture(EA)plus collateral-pricking and cupping therapy for herpes zoster.Methods:Fifty-three cases with herpes zoster were randomly divided into two groups.Thirty-one cases in the treatment group were treated with EA at Jiaji(EX-B 2)points plus local collateral-pricking and cupping therapy.Twenty-two cases in the control group were treated with oral administration of Valaciclovir Hydrochloride and Indomethacin.Results:The curative and remarkable effective rate was 93.5%in the treatment group and 72.7%in the control group.The difference between the two groups was statistically significant(P<0.01),indicating that EA plus collateral-pricking and cupping therapy is better than Western medications in the clinical effects for herpes zoster.Conclusion:The EA plus collateral-pricking and cupping method is an effective therapy for herpes zoster. | Liu Yin-ni Zhang Hong-xing Huang Guo-fu Zou Ran Wei Wei Huang Guo-qi | 2013 | Journal of Acupuncture and Tuina Science2013，11，5： | 9 |
