| 1 | Field experiment on a robust hierarchical metropolitan quantum cryptography network显示文摘A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node backbone net with one node acting as the subnet gateway, a two-user subnet and a single-fiber access link, which is realized by the Faraday-Michelson interferometer set-ups. The techniques of the quantum router, optical switch and trusted relay are assembled here to guarantee the feasibility and expandability of the quantum cryptography network. Five nodes of the network are located in the government departments and the secure keys generated by the quantum key distribution network are utilized to encrypt the instant video, sound, text messages and confidential files transmitting between these bureaus. The whole implementation including the hierarchical quantum cryptographic communication network links and the corresponding application software shows a big step toward the practical user-oriented network with a high security level. | XU FangXing CHEN Wei WANG Shuang YIN ZhenQiang ZHANG Yang LIU Yun ZHOU Zheng ZHAO YiBo LI HongWei LIU Dong HAN ZhengFu GUO GuangCan | 2009 | Chinese Science Bulletin2009,54,17: | 40 |
| 2 | 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 |

| 10 | Inhibition of hepatitis B virus expression and replication by RNA interference in HepG2.2.15显示文摘AIM: To observe the inhibition of hepatitis B virus replication and expression by transfecting vector-based small interference RNA (siRNA) pGenesil-HBV X targeting HBV X gene region into HepG2.2.15 cells. METHODS: pGenesil-HBV X was constructed and trans- fected into HepG2.2.15 cells via lipofection. HBV antigen secretion was determined 24, 48, and 72 h after trans- fection by time-resolved immunofluorometric assays (TRFIA). HBV replication was examined by fluorescence quantitative PCR, and the expression of cytoplasmic viral proteins was determined by immunohistochemistry. RESULTS: The secretion of HBsAg and HBeAg into the supernatant was found to be inhibited by 28.5% and 32.2% (P < 0.01), and by 38.67% (P < 0.05) and 42.86% (P < 0.01) at 48 h and 72 h after pGenesil-HBV X transfection, respectively. Immunohistochemical stain- ing for cytoplasmic HBsAg showed a similar decline in HepG2.2.15 cells 48 h after transfection. The number of HBV genomes within culture supernatants was also sig- nifi cantly decreased 48 h and 72 h post-transfection as quantifi ed by fluorescence PCR (P < 0.05). CONCLUSION: In HepG2.2.15 cells, HBV replication and expression is inhibited by vector-based siRNA pGenesil- HBV X targeting the HBV X coding region. | Zhong-Fu Zhao Hui Yang De-Wu Han Long-Feng Zhao Guo-Ying Zhang Yun Zhang Ming-She Liu | 2006 | World Journal of Gastroenterology2006,12,37: | 14 |
| 11 | Colonoscopy evaluation after short-term anti-tuberculosis treatment in nonspecific ulcers on the ileocecal area显示文摘AIM: To evaluate the eff icacy of colonoscopy follow-up after short-term anti-tuberculosis treatment in patients with nonspecific ulcers on ileocecal areas being suspicious of tuberculous colitis. METHODS: We prospectively analyzed the colonoscopic fi ndings before and after short term anti- tuberculosis treatment in 18 patients with nonspecifi c ulcers on the ileocecal area and compared them with 7 patients of confi rmed tuberculous colitis by acid-fast bacilli or caseating granuloma on colonic biopsy. RESULTS: Mean duration for short-term follow- up was 107.3 d with combined chemotherapy containing isoniazid, rifampicin, ethambutol and pyrazinamide. Seven patients with tuberculous colitis showed complete healing of active ulcers after short- term medication. After short-term anti-tuberculosis treatment, follow-up colonoscopy findings devided 18 patients with nonspecific ulcers into two groups by ulcer state. One is the 'suspicious tuberculous colitis group' showing healing of ulcers and erosions and another is the 'suspicious inflammatory bowel disease group' showing active ulcers with or without aggravation of the lesion. Finally, all 9 of the 'suspicious tuberculous colitis group' were diagnosed as tuberculous colitis showing no recurrence of ulcers after termination of 9 mo of anti-tuberculosis medication. Patients of the 'suspicious inflammatorybowel disease group' were f inally diagnosed as Crohn's disease or nonspecifi c colonic ulcers during long-term follow up. CONCLUSION: Follow-up colonoscopy shows a healing stage ulcer or scarring change without an active ulcer with just 2 mo to 3 mo of medication in patients with tuberculous colitis. Colonoscopy follow-up after short term anti-tuberculosis trial in patients with nonspecif ic ulcers on the ileocecal area is valuable in making early differential diagnosis of tuberculous colitis. | Young Sook Park Dae Won Jun Seong Hwan Kim Han Hyo Lee Yun Ju Jo Moon Hee Song Nam In Kim Jun Seok Lee | 2008 | World Journal of Gastroenterology2008,14,32: | 14 |

| 14 | MiR-182 is up-regulated and targeting Cebpa in hepatocellular carcinoma显示文摘MicroRNAs(miRNAs) are endogenous small non-coding RNAs that repress their targets at post transcriptional level.Existing studies have shown that miRNAs are important regulatory genes in hepatocellular carcinoma(HCC),as either tumor suppressors or oncogenes.MiR-122 is normally downregulated in HCC and regarded as a tumor suppressor.Recently miR-122 has been reported to be regulated by CEBPA,which is then involved in a novel pathway to influence proliferation of tumor cells.However it is unknown whether CEBPA is regulated by miRNAs in HCC.In this study,we find that miR-182 is upregulated in HCC model rat,and represses CEBPA in both rat and human.This further improves the current CEBPA/miR-122 pathway that controls the proliferation of tumor cells.These results suggest that miR-182 is a potential oncogene in HCC and could be used as a diagnostic marker and drug target of HCC. | Chenggang Wang Ren Ren Haolin Hu Changjun Tan Miao Han Xiaolin Wang Yun Zheng | 2014 | Chinese Journal of Cancer Research2014,26,1: | 13 |
| 15 | Chinese Medicine Sequential Therapy Improves Pregnancy Outcomes after Surgery for Endometriosis-Associated Infertility: A Multicenter Randomized Double-blind Placebo Parallel Controlled Clinical Trial显示文摘Objective:To evaluate the efficacy and safety of Chinese medicine(CM)improving pregnancy outcomes after surgery for endometriosis-associated infertility.Methods:A multicenter,randomized,doubleblind placebo parallel controlled clinical trial was designed.A total of 202 patients who had laparoscopy for endometriosis-associated infertility with qi stagnation and blood stasis syndrome were included and randomly divided into the CM treatment group and placebo control group at a ratio of 1:1 using a central block randomization from May 2014 to September 2017,101 patients in each group.The two groups received continuous intervention at 1–5 days after surgery,for 6 menstrual cycles.Before ovulation,the CM group was treated Huoxue Xiaoyi Granule(活血消异颗粒);after ovulation,Bushen Zhuyun Granule(补肾助孕颗粒)was involved.The control group was treated with placebo.Transvaginal ultrasonography was performed every menstrual cycle during the treatment,and female hormone levels in the follicular and luteal phases were measured during the 1 st,3 rd and 6 th menstrual cycles.The analysis was continued until pregnancy.The primary outcomes were clinical pregnancy rate and pregnancy outcome,and the secondary outcomes were follicular development and endometrial receptivity.Safety evaluations were performed before and after treatment.Results:(1)Clinical pregnancy and live birth rates:the clinical pregnancy and live birth rates of the CM group were significantly higher than those of the placebo group[44.6%(45/101)vs.29.7%(30/101),34.7%(35/101)vs.20.8%(21/101),both P<0.05].(2)Follicle development:the incidence of dominant follicles,rate of cumulative cycle ovulation,and rate of cumulative cycle mature follicle ovulation were significantly higher in the CM group than those in the placebo group[93.8%(350/373)vs.89.5%(341/381),80.4%(275/342)vs.69.1%(253/366),65.8%(181/275)vs 56.1%(142/253),P<0.05 or P<0.01]).The incidence of cumulative cycle luteinized unruptured follicle syndrome was significantly lower in the CM group than in the placebo group[11.7%(40/342)vs.17.8%(65/366),P<0.05).(3)Endometrial receptivity:after treatment,both endometrial types and endometrial blood flow types in the CM group were mainly types A and B,while those in the placebo group were mainly types B and C,with a significant difference between the two groups(both P<0.05).(4)Adverse events:the incidence of adverse events between the two groups was not significantly different(P>0.05).Conclusion:Strategies for activating blood circulation-regulating Gan(Liver)-tonifying Shen(Kidney)sequential therapy can effectively improve the clinical pregnancy rate and live birth rate of endometriosis-associated infertility with qi stagnation and blood stasis after laparoscopy,improve follicular development,promote ovulation,improve endometrial receptivity,while being a safe treatment option.(Trial registration No.NCT02676713). | ZHAO Rui-hua LIU Yong LU Dan WU Ying WANG Xiao-yun LI Wei-li ZENG Cheng MENG Qing-wei LIAN Feng-mei ZHOU Jun SHI Yun SUN Wei-wei HAN Qian TANG Yi SHI Guang | 2020 | Chinese Journal of Integrative Medicine2020,26,2: | 13 |
| 16 | Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders. | XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu | 2015 | Science China(Life Sciences)2015,58,9: | 12 |

| 18 | Flow separation control on swept wing with nanosecond pulse driven DBD plasma actuators显示文摘A 15° swept wing with dielectric barrier discharge plasma actuator is designed.Experimental study of flow separation control with nanosecond pulsed plasma actuation is performed at flow velocity up to 40 m/s. The effects of the actuation frequency and voltage on the aerodynamic performance of the swept wing are evaluated by the balanced force and pressure measurements in the wind tunnel. At last, the performances on separation flow control of the three types of actuators with plane and saw-toothed exposed electrodes are compared. The optimal actuation frequency for the flow separation control on the swept wing is detected, namely the reduced frequency is 0.775, which is different from 2-D airfoil separation control. There exists a threshold voltage for the low swept wing flow control. Before the threshold voltage, as the actuation voltage increases, the control effects become better. The maximum lift is increased by 23.1% with the drag decreased by 22.4% at 14°, compared with the base line. However, the best effects are obtained on actuator with plane exposed electrode in the low-speed experiment and the abilities of saw-toothed actuators are expected to be verified under high-speed conditions. | Zhao Guangyin Li Yinghong Liang Hua Han Menghu Wu Yun | 2015 | Chinese Journal of Aeronautics2015,28,2: | 10 |
| 19 | Very high baseline HIV viremia impairs efficacy of non-nucleoside reverse transcriptase inhibitor-based ART:a longterm observation in treatment-naïve patients显示文摘Background:It is not completely clear whether a very high pre-therapy viral load(≥500000 copies/ml)can impair the virological response.The aim of this study was to examine the influence of very high baseline HIV-RNA levels on long-term virological responses under one type of regimen.Methods:A retrospective study was performed based on data from two multicenter cohorts in China from January to November 2009,and from May 2013 to December 2015.Untreated HIV infected adults between 18 and 65 years old were recruited before receiving non-nucleoside reverse transcriptase inhibitor-based regimen.All patients had baseline HIV-RNA levels over 500 copies/ml,good adherence,and were followed for at least 24 weeks.Virological suppression was defined as the first HIV-RNA<50 copies/ml.Virological failure was defined as any of incomplete viral suppression(HIV-RNA≥200 copies/ml without virological suppression within 24 weeks of treatment)and viral rebound(confirmed HIV-RNA level≥50 copies/ml after virological suppression).Chi-square test,Kaplan–Meier analysis,Cox proportional hazards model and Logistic regression were used to compare virological response between each pretreated viral load stratum.Results:A total of 758 treatment-naïve HIV patients in China were enlisted.Median follow-up time(IQR)was 144(108–276)weeks.By week 48,rates of virological suppression in three groups(<100000,100000–500000 and≥500000 copies/ml)were 94.1,85.0,and 63.8%,respectively(P<0.001).Very high baseline HIV viremia over 500000 copies/ml were found to be associated with delayed virological suppression(≥500000 vs<100000,adjusted relative hazard=0.455,95%CI:0.32–0.65;P<0.001)as well as incomplete viral suppression(≥500000 vs<100000,adjusted odds ratio[aOR]=6.084,95%CI:2.761–13.407;P<0.001)and viral rebound(≥50000 vs<100000,aOR=3.671,95%CI:1.009–13.355,P=0.048).Conclusions:Very high levels of pre-treatment HIV-RNA were related with delayed efficacy of NNRTI-based ART and increased risk of treatment failure.More potent initial regimens should be considered for those with this clinical character. | Shuai Chen Yang Han Xiao-Jing Song Yan-ling Li Ting Zhu Hong-Zhou Lu Xiao-Ping Tang Tong Zhang Min Zhao Yun He Sheng-Hua He Min Wang Yong-Zhen Li Shao-Biao Huang Yong Li Jing Liu Wei Cao Tai-Sheng Li | 2020 | Infectious Diseases of Poverty2020,9,3: | 10 |
