22018 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
3Traditional herbal medicine in preventing recurrence after resection of small hepatocellular carcinoma: a multicenter randomized controlled trial显示文摘BACKGROUND: Disease recurrence is a main challenge in treatment of hepatocellular carcinoma (HCC). There is no generally accepted method for preventing recurrence of HCC after resection. OBJECTIVE: To compare the efficacy of a traditional herbal medicine (THM) regimen and transarterial chemoembolization (TACE) in preventing recurrence in post-resection patients with small HCC. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a multicenter, open-label, randomized, controlled study, which was undertaken in five centers of China. A total of 379 patients who met the eligibility criteria and underwent randomization were enrolled in this trial. One hundred and eighty-eight patients were assigned to the THM group and received Cinobufacini injection and Jiedu Granule, and the other 191 patients were assigned to the TACE group and received one single course of TACE. MAIN OUTCOME MEASURES: Primary outcome measures were the annual recurrence rate and the time to recurrence. Incidence of adverse events was regarded as the secondary outcome measure. RESULTS: Among the 364 patients who were included in the intention-to-treat analysis, 67 patients of the THM group and 87 of the TACE group had recurrence, with a hazard ratio of 0.695 (P = 0.048). Median recurrence-free survival of the patients in the THM and TACE groups was 46.89 and 34.49 months, respectively. Recurrence rates at 1, 2 and 3 years were 17.7%, 33.0% and 43.5% for the THM group, and 28.8%, 42.5% and 54.0% for the TACE group, respectively (P = 0.026). Multivariate analysis indicated that the THM regimen had a big advantage for prolonging the recurrence-free survival. Adverse events were mild and abnormality of laboratory indices of the two groups were similar. CONCLUSION: In comparison with TACE therapy, the THM regimen was associated with diminished risk of recurrence of small-sized HCC after resection, with comparable adverse events. TRIAL REGISTRTION IDENTIFIER: This trial was registered in the Chinese Clinical Trial Registry with the identifier ChiCTR-TRC-07000033.Xiao-feng Zhai Zhe Chen Bai Li Feng Shen Jia Fan Wei-ping Zhou Yun-ke Yang Jing Xu Xiao Qin Le-qun Li Chang-quan Ling 2013Journal of Integrative Medicine2013,11,2:49

6Expenditure and financial burden for the diagnosis and treatment of colorectal cancer in China:a hospital.based,multicenter,cross-sectional survey显示文摘Background: The increasing prevalence of colorectal cancer(CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment. We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods: We conducted a multicenter, cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014. Each enrolled patient was interviewed using a structured questionnaire. All expenditure data were inflated to the 2014 Chinese Yuan(CNY; 1 CNY = 0.163 USD). We quantified the overall expenditure and financial burden and by subgroup(hospital type, age at diagnosis, sex, education, occupation, insurance type, household income, clinical stage, pathologic type, and therapeutic regimen). We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results: A total of 2356 patients with a mean age of 57.4 years were included, 57.1 % of whom were men; 13.9% of patients had stage I cancer; and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY, and the expenditures for stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ disease were 56,099 CNY, 59,952 CNY, 67,292 CNY, and 82,729 CNY, respectively. Non-medical expenditure accounted for 8.3%of the overall expenditure. The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY, which accounted for 59.9% of their previous-year household income and caused 75.0% of families to suffer an unmanageable financial burden. Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups(P < 0.05), except for sex. Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less(all P < 0.05).Conclusions: For patients in China, direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable. The financial burden varied among subgroups, especially among patients with different clinical stages of disease, which suggests that, in China, CRC screening might be cost-effective.Hui-Yao Huang Ju-Fang Shi Lan-Wei Guo Ya-Na Bai Xian-Zhen Liao Guo-iangLiu A-Yan Mao Jian-Song Ren Xiao-Jie Sun Xin-Yu Zhu Le Wang Bing-Bing Song Ling-Bin Du Lin Zhu Ji-Yong Gong Qi Zhou Yu-Qin Liu Rong Cao Ling Mai Li Lan Xiao-Hua Sun Ying Ren Jin-Yi Zhou Yuan-Zheng Wang Xiao Qi Pei-An Lou Dian Shi Ni Li Kai Zhang Jie He Min Dai 2017Chinese Journal of Cancer2017,36,8:25
7Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design.SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng 2012Biomedical and Environmental Sciences2012,25,2:23
8Guidance for the clinical evaluation of traditional Chinese medicine-induced liver injury Issued by China Food and Drug Administration显示文摘1.

This type of injury can cause acute liver failure and even death in severe cases5.Xiaohe Xiao Jianyuan Tang Yimin Mao Xiuhui Li Jiabo Wang Chenghai Liu Kewei Sun Yong’an Ye Zhengsheng Zou Cheng Peng Ling Yang Yuming Guo Zhaofang Bai Tingting He Jing Jing Fengyi Li Na An 2019Acta Pharmaceutica Sinica B2019,9,3:22
9Isolation and characterization of dengue virus serotype 2 from the large dengue outbreak in Guangdong, China in 2014显示文摘Dengue has been well recognized as a global public health threat,but only sporadic epidemics and imported cases were reported in recent decades in China.Since July 2014,an unexpected large dengue outbreak has occurred in Guangdong province,China,resulting in more than 40000 patients including six deaths.To clarify and characterize the causative agent of this outbreak,the acute phase serum from a patient diagnosed with severe dengue was subjected to virus isolation and high-throughput sequencing(HTS).Traditional real-time RT-PCR and HTS with Ion Torrent PGM detected the presence of dengue virus serotype 2(DENV-2).A clinical DENV-2 isolate GZ05/2014 was obtained by culturing the patient serum in mosquito C6/36 cells.The complete genome of GZ05/2014 was determined and deposited in Gen Bank under the access number KP012546.Phylogenetic analysis based on the complete envelope gene showed that the newly DENV-2 isolate belonged to Cosmopolitan genotype and clustered closely with other Guangdong strains isolated in the past decade.No amino acid mutations that are obviously known to increase virulence or replication were identified throughout the genome of GZ05/2014.The high homology of Guangdong DENV-2 strains indicated the possibility of establishment of local DENV-2 circulation in Guangdong,China.These results help clarify the origin of this epidemic and predict the future status of dengue in China.ZHAO Hui ZHAO Ling Zhai JIANG Tao LI Xiao Feng FAN Hang HONG Wen Xin ZHANG Yu ZHU Qin YE Qing TONG Yi Gang CAO Wu Chun ZHANG Fu Chun QIN Cheng Feng 2014Science China(Life Sciences)2014,57,12:21

12Comprehensive mutation screening for 10 genes in Chinese patients suffering very early onset inflammatory bowel disease显示文摘AIM: To perform sequencing analysis in patients with very early-onset inflammatory bowel disease(VEO-IBD) to determine the genetic basis for VEO-IBD in Chinese pediatric patients.METHODS: A total of 13 Chinese pediatric patients with VEO-IBD were diagnosed from May 2012 and August 2014. The relevant clinical characteristics of these patients were analyzed. Then DNA in the peripheral blood from patients was extracted. Next generation sequencing(NGS) based on an IlluminaMiseq platform was used to analyze the exons in the coding regions of 10 candidate genes: IL-10, IL-10 RA, IL-10 RB, NOD2, FUT2, IL23 R, GPR35, GPR65, TNFSF15, and ADAM30. The Sanger sequencing was used to verify the variations detected in NGS.RESULTS: Out of the 13 pediatric patients, ten were diagnosed with Crohn's disease, and three diagnosed with ulcerative colitis. Mutations in IL-10 RA and IL-10 RB were detected in five patients. There were four patients who had single nucleotide polymorphisms associated with IBD. Two patients had IL-10 RA andFUT2 polymorphisms, and two patients had IL-10 RB and FUT2 polymorphisms. Gene variations were not found in the rest four patients. Children with mutations had lower percentile body weight(1.0% vs 27.5%, P = 0.002) and hemoglobin(87.4 g/L vs 108.5 g/L, P = 0.040) when compared with children without mutations. Although the age of onset was earlier, height was shorter, and the response to treatment was poorer in the mutation group, there was no significant difference in these factors between groups.CONCLUSION: IL-10 RA and IL-10 RB mutations are common in Chinese children with VEO-IBD. Patients with mutations have an earlier disease onset, lower body weight and hemoglobin, and poorer prognosis.Yuan Xiao Xin-Qiong Wang Yi Yu Yan Guo Xu Xu Ling Gong Tong Zhou Xiao-Qin Li Chun-Di Xu 2016World Journal of Gastroenterology2016,22,24:20
13Whole-genome sequencing of 508 patients identifies key molecular features associated with poor prognosis in esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma(ESCC)is a poor-prognosis cancer type with limited understanding of its molecular etiology.Using 508 ESCC genomes,we identified five novel significantly mutated genes and uncovered mutational signature clusters associated with metastasis and patients’outcomes.Several functional assays implicated that NFE2L2 may act as a tumor suppressor in ESCC and that mutations in NFE2L2 probably impaired its tumor-suppressive function,or even conferred oncogenic activities.Additionally,we found that the NFE2L2 mutations were significantly associated with worse prognosis of ESCC.We also identified potential noncoding driver mutations including hotspot mutations in the promoter region of SLC35E2 that were correlated with worse survival.Approximately 5.9%and 15.2%of patients had high tumor mutation burden or actionable mutations,respectively,and may benefit from immunotherapy or targeted therapies.We found clinically relevant coding and noncoding genomic alterations and revealed three major subtypes that robustly predicted patients’outcomes.Collectively,we report the largest dataset of genomic profiling of ESCC useful for developing ESCC-specific biomarkers for diagnosis and treatment.Yongping Cui Hongyan Chen Ruibin Xi Heyang Cui Yahui Zhao Enwei Xu Ting Yan Xiaomei Lu Furong Huang Pengzhou Kong Yang Li Xiaolin Zhu Jiawei Wang Wenjie Zhu Jie Wang Yanchun Ma Yong Zhou Shiping Guo Ling Zhang Yiqian Liu Bin Wang Yanfeng Xi Ruifang Sun Xiao Yu Yuanfang Zhai Fang Wang Jian Yang Bin Yang Caixia Cheng Jing Liu Bin Song Hongyi Li Yi Wang Yingchun Zhang Xiaolong Cheng Qimin Zhan Yanhong Li Zhihua Liu-Show 2020Cell Research2020,30,10:19
14H_2S Protecting against Lung Injury following Limb Ischemia-reperfusion by Alleviating Inflammation and Water Transport Abnormality in Rats显示文摘Objective To investigate the effect of H2 S on lower limb ischemia-reperfusion(LIR) induced lung injury and explore the underlying mechanism. Methods Wistar rats were randomly divided into control group, IR group, IR+ Sodium Hydrosulphide(NaHS) group and IR+ DL-propargylglycine(PPG) group. IR group as lung injury model induced by LIR were given 4 h reperfusion following 4 h ischemia of bilateral hindlimbs with rubber bands. NaHS(0.78 mg/kg) as exogenous H2 S donor and PPG(60 mg/kg) which can suppress endogenous H2 S production were administrated before LIR, respectively. The lungs were removed for histologic analysis, the determination of wet-to-dry weight ratios and the measurement of mRNA and protein levels of aquaporin-1(AQP1), aquaporin-5(AQP5) as indexes of water transport abnormality, and mRNA and protein levels of Toll-like receptor 4(TLR4), myeloid differentiation primary-response gene 88(MyD88) and p-NF-κB as indexes of inflammation. Results LIR induced lung injury was accompanied with upregulation of TLR4-Myd88-NF-κB pathway and downregulation of AQP1/AQP5. NaHS pre-treatment reduced lung injury with increasing AQP1/AQP5 expression and inhibition of TLR4-Myd88-NF-κB pathway, but PPG adjusted AQP1/AQP5 and TLR4 pathway to the opposite side and exacerbated lung injury. Conclusion Endogenous H2 S, TLR4-Myd88-NF-κB pathway and AQP1/AQP5 were involved in LIR induced lung injury. Increased H2 S would alleviate lung injury and the effect is at least partially depend on the adjustment of TLR4-Myd88-NF-κB pathway and AQP1/AQP5 expression to reduce inflammatory reaction and lessen pulmonary edema.QI Ying Chun CHEN Wen LI Xiao Ling WANG Yu Wei XIE Xiao Hua 2014Biomedical and Environmental Sciences2014,27,6:17

16Report on Childhood Obesity in China (10): Association of Sleep Duration with Obesity显示文摘Objectives To explore the association of sleep duration with obesity among children in urban areas of China.Methods A total of 6 576 children(3 293 boys and 3 283 girls) aged 7-11 years were randomly selected from 36 primary schools in 6 metropolitan cities in China.A 7-day Physical Activity Recall was used to assess the sleep duration and physical activity level.The height,weight,waist circumference(WC) and percentage of body fat(%BF,as determined by bioelectrical impedance analysis technique) were measured by following the standardized operation procedures.The information on demography,lifestyle and eating habits was collected with a self-administered questionnaire from participants and their parents.Results The average sleep duration per night in the children was 9.7 h with the decreasing trends along with the increase of age(P<0.05).The sleep duration was negatively associated with body mass index(BMI) and WC in both boys and girls after adjustment for confounders(β value-0.23 and-0.82 for boys,-0.24 and-0.91 for girls,respectively,P<0.01).However,no significant association of sleep duration with %BF was found.Children who slept less than 9.0 h per night had a higher risk for overweight and obesity(OR=1.29,95% CI:1.01,1.64) and abdominal obesity(OR=1.38,95% CI:1.04,1.83) as compared with those who slept for 10.0-10.9 h.Conclusions Short sleep duration is associated with obesity.It is important to ensure adequate sleep duration of children and foster their healthy lifestyle at an early stage of life.MENG Li Ping LIUAi Ling HU Xiao Qi ZHANG Qian DU Song Ming FANG Hong Yun MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin MA Guan Sheng 2012Biomedical and Environmental Sciences2012,25,2:16
17OB glue paste technique for establishing nude mouse human gastric cancer orthotopic transplantation models显示文摘AIM: To establish nude mouse human gastric cancer orthotopic transplantation models using OB glue paste technique. METHODS: Using OB glue paste technique, orthtopic transplantation models were established by implanting SGC-7901 and MKN-45 human gastric cancer cell strains into the gastric wall of nude mice. Biological features, growth of the implanted tumors, the success rate of transplantation and the rate of auto-metastasis of the two models were observed. RESULTS: The success rates of orthotopic transplan- tation of the two models were 94.20% and 96%. The rates of hepatic metastasis, pulmonary metastasis, peritoneal metastasis, lymphocytic metastasis and splenic metastasis were 42.13% and 94.20%, 48.43% and 57.97%, 30.83% and 36.96%, 67.30% and 84.06%, and 59.75% and 10.53%, respectively. The occurrence of ascites was 47.80% and 36.96%. CONCLUSION: OB glue paste technique is easy to follow. The biological behaviors of the nude mouse human gastric cancer orthotopic transplantation models established with this technique are similar to the natural processes of growth and metastasis of human gastric cancer, and, therefore, can be used as an ideal model for experimental research of proliferative metastasis of tumors.Jun Shi Pin-Kang Wei Shen Zhang Zhi-Feng Qin Jun Li Da-Zhi Sun Yan Xiao Zhi-Hong Yu Hui-Ming Lin Guo-Jing Zheng Xiao-Mei Su Ya-Lin Chen Yan-Fang Liu Ling Xu 2008World Journal of Gastroenterology2008,14,30:15

19Outcomes of preoperative chemoradiotherapy followed by surgery in patients with unresectable locally advanced sigmoid colon cancer显示文摘Background: Complete resection of locally advanced sigmoid colon cancer(LASCC) is sometimes difficult. Patients with LASCC have a dismal prognosis and poor quality of life, which has encouraged the evaluation of alternative multimodality treatments. This prospective study aimed to assess the feasibility and efficacy of neoadjuvant chemora?diotherapy(neo CRT) followed by surgery as treatment of selected patients with unresectable LASCC.Methods: We studied the patients with unresectable LASCC who received neo CRT followed by surgery between October 2010 and December 2012. The neoadjuvant regimen consisted of external?beam radiotherapy to 50 Gy and capecitabine?based chemotherapy every 3 weeks. Surgery was scheduled 6–8 weeks after radiotherapy.Results: Twenty?one patients were included in this study. The median follow?up was 42 months(range, 17–57 months). All patients completed neo CRT and surgery. Resection with microscopically negative margins(R0 resection) was achieved in 20 patients(95.2%). Pathologic complete response was observed in 8 patients(38.1%). Multivisceral resection was necessary in only 7 patients(33.3%). Two patients(9.5%) experienced grade 2 postopera?tive complications. No patients died within 30 days after surgery. For 18 patients with pathologic M0(yp M0) disease, the cumulative probability of 3?year local recurrence?free survival, disease?free survival and overall survival was 100.0%, 88.9% and 100.0%, respectively. For all 21 patients, the cumulative probability of 3?year overall survival was 95.2% and bladder function was well preserved.Conclusion: For patients with unresectable LASCC, preoperative chemoradiotherapy and surgery can be performed safely and may result in an increased survival rate.Bo Qiu Pei-Rong Ding Ling Cai Wei-Wei Xiao Zhi-Fan Zeng Gong Chen Zhen-Hai Lu Li-Ren Li Xiao-Jun Wu Rene-Olivier Mirimanoff Zhi-Zhong Pan Rui-Hua Xu Yuan-Hong Gao 2016Chinese Journal of Cancer2016,35,10:14
20The Predictive Value of Baseline HBs Ag Level and Early Response for HBs Ag Loss in Patients with HBe Ag-positive Chronic Hepatitis B during Pegylated Interferon Alpha-2a Treatment显示文摘Objective To explore the predictive value of baseline HBsAg level and early response for HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment. Methods A total of 121 patients with HBeAg-positive chronic hepatitis B who achieved HBsAg loss were enrolled; all patients were treated with PEG-IFNα-2a 180 μg/week. Serum HBV DNA and serological indicators(HBsAg, anti-HBs, HBeAg, and anti-HBe) were determined before and every 3 months during treatment. Results The median treatment time for HBsAg loss was 84 weeks(7-273 weeks), and 74.38%(90 cases) of the patients needed extended treatment(> 48 weeks). The correlation between baseline HBsAg levels and the treatment time of HBsAg loss was significant(B = 14.465, t = 2.342, P = 0.021). Baseline HBsAg levels together with the decline range of HBsAg at 24 weeks significantly correlated with the treatment time of HBsAg loss(B = 29.862, t = 4.890, P = 0.000 and B = 27.993, t = 27.993, P = 0.005). Conclusion Baseline HBsAg levels and extended therapy are critical steps toward HBsAg loss. Baseline HBsAg levels together with early response determined the treatment time of HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment.LI Ming Hui ZHANG Lu QU Xiao Jing LU Yao SHEN Ge LI Zhen Zhen WU Shu Ling LIU Ru Yu CHANG Min HU Lei Ping HUA Wen Hao SONG Shu Jing WAN Gang XIE Yao 2017Biomedical and Environmental Sciences2017,30,3:14
