1Locoregional radiotherapy in patients with distant metastases of nasopharyngeal carcinoma at diagnosis显示文摘Systemic chemotherapy is the basic palliative treatment for metastatic nasopharyngeal carcinoma(NPC); however, it is not known whether locoregional radiotherapy targeting the primary tumor and regional lymph nodes affects the survival of patients with metastatic NPC. Therefore, we aimed to retrospectively evaluate the benefits of locoregional radiotherapy. A total of 408 patients with metastatic NPC were included in this study. The mortality risks of the patients undergoing supportive treatment and those undergoing chemotherapy were compared with that of patients undergoing locoregional radiotherapy delivered alone or in combination with chemotherapy. Univariate and multivariate analyses were conducted. The contributions of independent factors were assessed after adjustment for covariates with significant prognostic associations (P<0.05). Both locoregional radiotherapy and systemic chemotherapy were identified as significant independent prognostic factors of overall survival(OS). The mortality risk was similar in the group undergoing locoregional radiotherapy alone and the group undergoing systemic chemotherapy alone [multi-adjusted hazard ratio(HR)=0.9, P=0.529]; this risk was 60% lower than that of the group undergoing supportive treatment(HR=0.4, P=0.004) and 130% higher than that of the group undergoing both systemic chemotherapy and locoregional radiotherapy(HR=2.3, P<0.001). In conclusion, locoregional radiotherapy, particularly when combined with systemic chemotherapy, is associated with improved survival of patients with metastatic NPC.Ming-Yuan Chen Rou Jiang Ling Guo Xiong Zou Qing Liu Rui Sun Fang Qiu Zhong-Jun Xia Hui-Qiang Huang Li Zhang Ming-Huang Hong Hai-Qiang Mai Chao-Nan Qian 2013Chinese Journal of Cancer2013,32,11:13
2Uptake of HIV Self-testing among Men Who have Sex with Men in Beijing, China: a Cross-sectional Study显示文摘Objective To examine HIV self-testing uptake and its determinates among men who have sex with men(MSM) in Beijing, China. Methods A cross-sectional online survey was conducted in Beijing, China in 2016. Participants were users of a popular Chinese gay networking application and had an unknown or negative HIV status. Univariate and multivariate logistic regression analyses were conducted to examine factors associated with HIV self-testing based on adjusted odds ratio(AOR) and 95% confidence interval(CI). Results Among the 5,996 MSM included in the study, 2,383(39.7%) reported to have used HIV self-testing kits. Willingness to use an HIV self-test kit in the future was expressed by 92% of the participants. High monthly income(AOR = 1.49; CI = 1.10-2.02; P = 0.010), large number of male sex partners(≥ 2: AOR = 1.24; CI = 1.09-1.43; P = 0.002), sexual activity with commercial male sex partners(≥ 2: AOR = 1.94; CI = 1.34-2.82; P = 0.001), long-term drug use(AOR = 1.42; CI = 1.23-1.62; P < 0.001), and long-term HIV voluntary counseling and testing(VCT) attendance(AOR = 3.62; CI = 3.11-4.22; P < 0.001) were all associated with increased odds of HIV self-testing uptake. Conclusion The nearly 40% rate of HIV self-testing uptake among MSM in our sample was high. In addition, an over 90% willingness to use kits in the future was encouraging. HIV self-testing could be an important solution to help China achieve the global target of having 90% of all people living with HIV diagnosed by 2020.REN Xian Long WU Zun You MI Guo Dong MCGOOGAN Jennifer ROU Ke Ming ZHAO Yan 2017Biomedical and Environmental Sciences2017,30,6:13
3A curative-intent endoscopic surgery for postradiation nasopharyngeal necrosis in patients with nasopharyngeal carcinoma显示文摘Background:Postradiation nasopharyngeal necrosis(PRNN)is a severe complication after radiotherapy in patients with nasopharyngeal carcinoma(NPC),which can severely affect the quality of life and threaten the patient’s life.Only 13.4%-28.6%of patients can be cured by traditional repeated endoscopic debridement.Here,we introduced an innovative curative-intent endoscopic surgery for PRNN patients and evaluated its clinical efficacy.Methods:Clinical data of 72 PRNN patients who underwent radical endoscopic necrectomy,followed by reconstruc-tion using a posterior pedicle nasal septum and floor mucoperiosteum flap were analyzed to determine the efficacy of this surgery.The endpoints were complete re-epithelialization of the nasopharyngeal defect,relief of headache,and overall survival(OS).Results:All surgeries were successfully performed without any severe postoperative complications or death.The median value of numeric rating scales of pain decreased from 8 before surgery to 0 after surgery(P<0.001).Fifty-one patients(70.8%)achieved complete re-epithelialization of the nasopharyngeal defect.The number of cycles of radiotherapy(odds ratio[OR],7.254;95%confidence interval[CI]1.035-50.821;P=0.046),postoperative pathological result(OR,34.087;95%CI 3.168-366.746;P=0.004),and survival status of flap(OR,261.179;95%CI 17.176-3971.599;P<0.001)were independent risk factors of re-epithelialization of the nasopharyngeal defects.Postoperative patho-logical result(hazard ratio[HR],5.018;95%CI 1.970-12.782;P=0.001)was an independent prognostic factor for OS.The 2-year OS rate of the entire cohort was 77.9%.Conclusion:Curative-intent endoscopic necrectomy followed by construction using the posterior pedicle nasal septum and floor mucoperiosteum flap is a novel,safe,and effective treatment of PRNN in patients with NPC.Xiong Zou Shun-Lan Wang You-Ping Liu Yan-Ling Liu Ru-Hai Zou Yi-Nuan Zhang Rui You Qi Yang Yu-Long Xie Mei Lin Pei-Yu Huang Rou Jiang Meng-Xia Zhang Chao-Nan Qian Hai-Qiang Mai Ling Guo Ming-Huang Hong Ming-Yuan Chen 2018Cancer Communications2018,38,1:11
4Viral and Bacterial Etiology of Acute Febrile Respiratory Syndrome among Patients in Qinghai, China显示文摘Objective This study was conducted to investigate the viral and bacterial etiology and epidemiology of patients with acute febrile respiratory syndrome(AFRS) in Qinghai using a commercial routine multiplex-ligation-nucleic acid amplification test(NAT)-based assay. Methods A total of 445 nasopharyngeal swabs specimens from patients with AFRS were analyzed using the RespiFinderSmart22 kit(PathoFinder BV, Netherlands) and the LightCycler 480 real-time PCR system. Results Among the 225(225/445, 51%) positive specimens, 329 positive pathogens were detected, including 298(90.58%) viruses and 31(9%) bacteria. The most commonly detected pathogens were influenza virus(IFV;37.39%;123/329), adenovirus(AdV;17.02%;56/329), human coronaviruses(HCoVs;10.94%;36/329), rhinovirus/enterovirus(RV/EV;10.03%;33/329), parainfluenza viruses(PIVs;8.51%;28/329), and Mycoplasma pneumoniae(M. pneu;8.51%;28/329), respectively. Among the co-infected cases(17.53%;78/445), IFV/AdV and IFV/M. pneu were the most common co-infections. Most of the respiratory viruses were detected in summer and fall. Conclusion In our study, IFV-A was the most common respiratory pathogen among 22 detected pathogens, followed by AdV, HCoV, RV/EV, PIV, and M. pneu. Bacteria appeared less frequently than viruses, and co-infection was the most common phenomenon among viral pathogens. Pathogens were distributed among different age groups and respiratory viruses were generally active in July, September, and November. Enhanced surveillance and early detection can be useful in the diagnosis, treatment, and prevention of AFRS, as well as for guiding the development of appropriate public health strategies.LIU Gao Shan LI Hong ZHAO Sheng Cang LU Rou Jian NIU Pei Hua TAN Wen Jie 2019Biomedical and Environmental Sciences2019,32,6:8
5Effect of Yiqi Tongyang Decoction(益气通阳方) on Blood T Cell Subsets in Patients with Chronic Immune Thrombocytopenia显示文摘Objective: To measure the proportions of blood T cel subsets, Th1, Th2, Th17, Th22, and Treg cel s, and other parameters in patients with chronic immune thrombocytopenia(CITP) before and after treatment with Yiqi Tongyang Decoction(益气通阳方, YTD) to explore T cel status of patients with CITP, and to define the mechanism of action of YTD. Methods: The changes in peripheral blood T lymphocyte subsets, and those of Th1, Th2, Th17, Th22, and Treg cel s in 30 patients with CITP(22 females and 8 males) were analyzed using multiparametric flow cytometry before and after treatment with YTD for 6 months, and 26 healthy volunteers(14 males and 12 females) acted as a control. T-box expressed in T-cel s(T-bet) and GATA binding protein 3(GATA-3) m RNA levels in patients and controls were analyzed using real-time reverse transcription-polymerase chain reaction. Results: The proportions of Th1, Th17, Th22, Th1/Th2, and Th17/Treg cells increased in the peripheral blood of patients with CITP compared to those in controls before YTD therapy(P<0.05). Th1 cel numbers and the Th1/Th2 ratio fel in the treated patients with CITP to approximate the values of the control group(P>0.05). Th17 cel numbers and the Th17/Treg ratio also decreased in the treatment group(P<0.05), but not to the levels of the controls. The number of Treg cel s in the peripheral blood of patients with CITP before treatment was lower than that in the control group(P<0.05), but increased after YTD treatment(P<0.05), but not to the level of controls. T-bet and GATA-3 m RNA levels in peripheral blood were initially higher in patients before treatment than controls(P<0.05), but decreased after YTD therapy(P<0.05). Conclusions: Imbalances in T lymphocyte levels, particularly those of Th1/Th2 and Th17/Treg cel s, play important roles in the pathogenesis of CITP. YTD efficiently regulated the dynamics of Th1/Th2 and Th17/Treg equilibria.YANG Xiu-peng MA Rou YANG Xiao-hong ZHU Hui-lan XU Yong-gang 2017Chinese Journal of Integrative Medicine2017,23,9:8
6Risk factors and therapeutic results of early local recurrence after transcatheter arterial chemoembolization显示文摘AIM:To identify factors affecting early local recurrence after transcatheter arterial chemoembolization(TACE)and investigate treatments and outcomes for local recurrence.METHODS:Early local recurrence and no early local recurrence groups drawn from 134 patients who were initially diagnosed with hepatocellular carcinoma(HCC)and showed a complete response(CR)to TACE treatment between January 1,2006,and January 31,2012,were analyzed by univariate and multivariate analyses.Additionally,the subsequent treatment for patients with recurrence was analyzed,and in cases in which TACE had been performed,the cumulative recurrence rates were calculated using the Kaplan-Meier method and compared with those of the primary lesion.RESULTS:The 1-,2-,and 3-year survival rates were92.3%,60.2%,and 39.8%,respectively,in the earlylocal recurrence group,which were significantly lower than those in both the late local and no local recurrence groups(P<0.001).On multivariate analyses,non-compact lipiodol uptake,large tumor size,and an alpha-fetoprotein>20 ng/mL after achieving a CR were significant predictors.When TACE was performed for early and late locally recurrent lesions,a CR was observed in 15 patients(41.7%)and 11 patients(78.6%),and the cumulative recurrence rates at 6,12,and 24mo were 17.9%,43.3%,and 71.2%,respectively,which did not differ significantly from those after the first CR of 20.5%,44.0%,and 58.6%,respectively(P=0.639).CONCLUSION:Closer monitoring and active treatments must be provided to patients with risk factors for early local recurrence of HCC.Woo Sun Rou Byung Seok Lee Hee Seok Moon Eaum Seok Lee Seok Hyun Kim Heon Young Lee 2014World Journal of Gastroenterology2014,20,22:7
7Competitive sorption between 17α-ethinyl estradiol and bisphenol A/4-n-nonylphenol by soils显示文摘The sorption of 17α-ethinyl estradiol(EE2),bisphenol A(BPA),and 4-n-nonylphenol(NP) in single systems and the sorption of EE2 with different initial aqueous concentrations of BPA or NP were examined using three soils.Results showed that all sorption isotherms were nonlinear and fit the Freundlich model.The degree of nonlinearity was in the order BPA(0.537-0.686) > EE2(0.705-0.858) > NP(0.875-0.0.951) in single systems.The isotherm linearity index of EE2 sorption calculated by the Freundlich model for Loam,Silt Loam and Silt increased from 0.758,0.705 and 0.858,to 0.889,0.910 and 0.969,respectively,when BPA concentration increased from 0 to 1000 μg/L,but the effect of NP was comparably minimal.Additionally,EE2 significantly suppressed the sorption of BPA,but insignificantly suppressed that of NP.These findings can be attributed to the difference of sorption affinity of EE2,NP and BPA on the hard carbon(e.g.,black carbon) of soil organic matter that dominated the sorption in the low equilibrium aqueous concentration range of endocrine-disrupting chemicals(EDCs).Competitive sorption among EDCs presents new challenges for predicting the transport and fate of EDCs under the influence of co-solutes.Jianzhong Li Lu Jiang Xi Xiang Shuang Xu Rou Wen Xiang Liu 2013Journal of Environmental Sciences2013,25,6:7
8Effect of Qinghuang Powder(青黄散) Combined with Bupi Yishen Decoction(补脾益肾方) in Treating Patients with Refractory Cytopenia with Multilineage Dysplasia through Regulating DNA Methylation显示文摘Objective: To explore the effect of Qinghuang Powder(QHP, 青黄散) combined with Bupi Yishen Decoction(BPYS, 补脾益肾方)on myelodysplastic syndromes(MDS) patients with refractory cytopenia with multilineage dysplasia(RCMD) and determine the change of DNA methylation in MDS-RCMD patients after the treatment of Chinese medicine formula. Methods: All 308 MDS-RCMD patients were treated with QHP combined with BPYS for 2 months at least, absolute neutrophil count(ANC), hemoglobin(Hb), platelets(PLT), primitive bone marrow cells and chromosome karyotype were chosen as the main evaluation indexes to analyze the treatment effect according to criteria from the MDS International Working Group. Then 43 bone marrow samples from 15 MDS-RCMD patients and 28 healthy donors were obtained for the examination of DNA methylation.Gene Ontology(GO) and Pathway analysis were applied to analyze the methylation data. Results: The overall MDS response rate to QHP was 61.68%(190/360) including hematologic improvement-neutrophil(HI-N) or hematologic improvement-erythroid(HI-E) or hematologic improvement-platelet(HI-P). Patients with anemia had a better response rate than patients with neutropenia or thrombocypenia(55.88% vs 31.54% or 55.88%vs. 36.9%). The DNA methylation microarray analysis disclosed that 4,257 hypermethylated genes were demethylated upon the treatment with QHP and BPYS. GO analysis and Pathway analysis showed that these demethylated genes were involved in a lot of tumor-related pathways and functions. Conclusions: QHP combined with BPYS could effectively treat MDS-RCMD patients through hematologic improvement(HI-N, HI-P or HI-E)and PLT and RBC transfusion independence due to the demethylation, thereby providing another choice for the treatment of patients with MDS-RCMD.ZHOU Qing-bing YANG Xiao-hong WANG Hong-zhi WANG De-xiu XU Yong-gang HU Xiao-mei XU Feng-qin MA Rou 2019Chinese Journal of Integrative Medicine2019,0,5:7
9Relation of Blood Arsenic Concentration with Effect and Safety of Arsenic-Containing Qinghuang Powder (青黄散) in Patients with Myelodysplastic Syndrome显示文摘Objective: To investigate the relation of blood arsenic concentration (BAC) with clinical effect and safety of arsenic-containing Qinghuang Powder (青黄散,QHP) in patients with myelodysplastic syndrome (MDS). Methods: Totally 163 patients with MDS were orally treated with QHP for 2 courses of treatment, 3 months as 1 course. The BACs of patients were detected by atomic fluoresce nee spectrophotometry at 1, 3, and 6 months during the treatment, and the effective rate, hematological improvement and safety in patients after treatment with QHP were analyzed. Results: After 2 courses of treatment, the total effective rate was 89.6%(146/163), with 31.3%(51/163) of hematological improvement and 58.3%(95/163) of stable disease. The hemoglobin increased from 73.48 ± 19.30 g/L to 80.39 ± 26.56 g/L (P<0.05), the absolute neutrophil count increased from 0.81 ±0.48 × 10^9/L to 1.08 ±0.62 × 1O^9/L (P<0.05), and no significant changes were observed in platelet counts (P>0.05). Among 46 patients previously depended on blood transfusion, 28.3%(13/46) completely got rid of blood transfusion and 21.7%(10/46) reduced the volume of blood transfusion by more than 50% after treatment. The BACs were significantly increased in patients treated for 1 month with 32.17 ± 18.04 jig/L (P<0.05), 3 months with 33.56 ±15.28 μg/L (P<0.05), and 6 months with 36.78 ±11.92 μg/L (P<0.05), respectively, as compared with those before treatment (4.08 ±2.11 ag/L). There were no significant differences of BACs among the patients treated for 1, 3 and 6 months (P>0.05). The adverse reactions of digestive tract during the treatment were mild abdominal pain and diarrhea in 14 cases (8.6%), and no patients discontinued the treatment. The BACs of patients with gastrointestinal adverse reactions were significantly lower than those without gastrointestinal adverse reactions (22.39 ±10.38 vs. 37.89 ± 11.84,μg/L, P<0.05). The BACs of patients with clinical effect were significantly higher than those failed to treatment (40.41 ± 11.69 vs. 23.84 ± 12.03,μg/L, P<0.05). Conclusion: QHP was effective and safe in the treatment of patients with MDS and the effect was associated with BACs of patients.DENG Zhong-yang ZHU Shi-rong WANG Ming-jing FANG Su ZHAO Pan ZHU Qian-zhe WANG Hong-zhi GUO Xiao-qing XU Yong-gang YI Bo-wen SHANG Xiao-hong MA Rou HU Xiao-mei 2019Chinese Journal of Integrative Medicine2019,25,7:7

11Role of miR-124 in the regulation of retinoic acid-induced Neuro-2A cell differentiation显示文摘Retinoic acid can cause many types of cells,including mouse neuroblastoma Neuro-2 A cells,to differentiate into neurons.However,it is still unknown whether microRNAs(miRNAs)play a role in this neuronal differentiation.To address this issue,real-time polymerase chain reaction assays were used to detect the expression of several differentiation-related miRNAs during the differentiation of retinoic acid-treated Neuro-2 A cells.The results revealed that miR-124 and miR-9 were upregulated,while miR-125 b was downregulated in retinoic acid-treated Neuro-2 A cells.To identify the miRNA that may play a key role,miR-124 expression was regulated by transfection of miRNA mimics or inhibitors.Morphological analysis results showed that inhibition of miR-124 expression reversed the effects of retinoic acid on neurite outgrowth.Moreover,miR-124 overexpression alone caused Neuro-2 A cells to differentiate into neurons,and its inhibitor could block this effect.These results suggest that miR-124 plays an important role in retinoic acid-induced differentiation of Neuro-2 A cells.Qun You Qiang Gong Yu-Qiao Han Rou Pi Yi-Jie Du Su-Zhen Dong 2020Neural Regeneration Research2020,15,6:4
12A nanocleaner specifically penetrates the blood-brain barrier at lesions to clean toxic proteins and regulate inflammation in Alzheimer's disease显示文摘Insurmountable blood-brain barrier(BBB) and complex pathological features are the key factors affecting the treatment of Alzheimer's disease(AD).Poor accumulation of drugs in lesion sites and undesired effectiveness of simply reducing Aβ deposition or TAU protein need to be resolved urgently.Herein,a nanocleaner is designed with a rapamycin-loaded ROS-responsive PLGA core and surface modification with KLVFF peptide and acid-cleavable DAG peptide [R@(ox-PLGA)-KcD].DAG can enhance the targeting and internalization effect of nanocleaner towards neurovascular unit endothelial cells in AD lesions,and subsequently detach from nanocleaner in response to acidic microenvironment of endosomes to promote the transcytosis of nanocleaner from endothelial cells into brain parenchyma.Then exposed KLVFF can capture and carry Aβ to microglia,attenuating Aβ-induced neurotoxicity.Strikingly,rapamycin,an autophagy promoter,is rapidly liberated from nanocleaner in the high ROS level of lesions to improve Aβ degradation and normalize inflammatory condition.This design altogether accelerates Aβ degradation and alleviates oxidative stress and excessive inflammatory response.Collectively,our finding offers a strategy to target the AD lesions precisely and multi-pronged therapies for clearing the toxic proteins and modulating lesion microenvironment,to achieve efficient AD therapy.Ting Lei Zhihang Yang Xue Xia Yuxiu Chen Xiaotong Yang Rou Xie Fan Tong Xiaolin Wang Huile Gao 2021Acta Pharmaceutica Sinica B2021,11,12:4
13Overview of bile acid signaling in the cardiovascular system显示文摘Bile acids(BAs)are classically known to play a vital role in the metabolism of lipids and in absorption.It is now well established that BAs act as signaling molecules,activating different receptors(such as farnesoid X receptor,vitamin D receptor,Takeda G-protein-coupled receptor 5,sphingosine-1-phosphate,muscarinic receptors,and big potassium channels)and participating in the regulation of energy homeostasis and lipid and glucose metabolism.In addition,increased BAs can impair cardiovascular function in liver cirrhosis.Approximately 50%of patients with cirrhosis develop cirrhotic cardiomyopathy.Exposure to high concentrations of hydrophobic BAs has been shown to be related to adverse effects with respect to vascular tension,endothelial function,arrhythmias,coronary atherosclerotic heart disease,and heart failure.The BAs in the serum BA pool have relevant through their hydrophobicity,and the lipophilic BAs are more harmful to the heart.Interestingly,ursodeoxycholic acid is a hydrophilic BA,and it is used as a therapeutic drug to reverse and protect the harmful cardiac effects caused by hydrophobic elevated BAs.In order to elucidate the mechanism of BAs and cardiovascular function,abundant experiments have been conducted in vitro and in vivo.The aim of this review was to explore the mechanism of BAs in the cardiovascular system.Rou Zhang Wen-Qi Ma Meng-Jun Fu Juan Li Chun-Hua Hu Yi Chen Mi-Mi Zhou Zhi-Jie Gao Ying-Li He 2021World Journal of Clinical Cases2021,9,2:4

15Arsenic concentration in peripheral blood is correlated with efficacy of a Traditional Chinese Medicine regimen containing realgar for the treatment of myelodysplastic syndromes显示文摘OBJECTIVE:To explore the relationship between the efficacy of realgar for the treatment of myelodysplastic syndromes with multilineage dysplasia(MDS-MLD)and arsenic concentration in the peripheral blood of patients.METHODS:In this prospective study,a total of 50 MDS-MLD patients were treated with traditional Chinese drugs containing realgar for 3 months in Xiyuan Hospital from March 2018 to January 2019.Routine blood examination as well as liver and kidney function were monitored before and after treatment.The concentration of arsenic in the peripheral blood was measured using an atomic fluorescence spectrometer after treatment.The correlation between clinical effect and arsenic concentration was analyzed by Spearman’s method.RESULTS:The treatment response rate was 54%.Two patients(4%)achieved complete remission,50%(25 of 50)showed hematologic improvement,and 23 patients had stable disease(23%).No disease progression was observed.Arsenic concentration in the peripheral blood ranged from 14.60 to 85.96μg/L.Clinical efficacy was positively correlated with arsenic concentration(P<0.05).The incidence of mild adverse reactions was 16%.CONCLUSION:A relatively high concentration of arsenic in the peripheral blood may improve the clinical efficacy of realgar in MDS-MLD patients.WANG Dexiu XU Yonggang DU Yu WANG Hongzhi LI Liu HU Xiaomei YANG Xiupeng MA Rou ZHOU Qingbing 2021Journal of Traditional Chinese Medicine2021,41,4:3
16Infectious Disease Surveillance in China显示文摘A national system of infectious disease surveillance was established in 1959 in China.Now it consists of three subunits, namely, national disease reporting system (NDRS), nationwide disease surveillance points (DSPs), and surveillance network for specific infectious diseases. There are 35 notifiable infectious diseases, which are divided into Classes A, B, and C. The functions of the surveillance include explaining the natural history of infectious diseases, describing the distribution of case occurrence, triggering disease-control effort, monitoring epidemic of infectious diseases during natural disasters, predicting and controlling epidemics and providing the base of policy adjustment.ZENG GUANG ZHANG JING-KUN ROU KE-MING, XU CHANG CHENG YING-KAI AND QI GUO-MING(The Institute of Epidemiology and Microbiology, Chinese Academy ofPreventive Medicine, Beijing 100050, China) 1998Biomedical and Environmental Sciences1998,11,1:3
17Antithymocyte globulin/antilymphocyte globulin plus kidney-nourishing Chinese Medicinal:effect on severe aplastic anemia显示文摘OBJECTIVE:To explore the effect of antithymocyte globulin(ATG)/antilymphocyte globulin(ALG) plus kidney-nourishing Chinese medicinal(KNCM) on severe aplastic anemia(SAA).METHODS:Twenty-five subjects of severe aplastic anemia were treated with ATG/ALD plus KNCM between 1992 and 2009,and the clinical data before and after treatment were collected and analyzed.RESULTS:Of the 25 patients,9 were nearly cured,6 were improved,5 were in remission,and 5 failed.The overall effective rate was 80.0%.The 3-year,5-year,10-year,15-year survival rate were respectively 98.6%,97.3%,97.3%,67.5%,and median survival time was 180 months.Compared to the conditions before administering the medication of ATG/ALG plus KNCM,after 2 weeks,reticulocyte was first improved(P=0.001);one month later,followed by palette(P=0.037);two months later,by neutrophil cell in peripheral blood(P=0.001);three months later,then by the hemoglobin(P=0.012).By conducting 1-year follow-up,1 case of complication-paroxysmal nocturnal hemoglobinuria(PNH) was identified and the patient still alive today.CONCLUSION:ATG/ALG plus KNCM had better effect on SAA and could improve patients' survival rate.Xudong Tang Feng Liu Liu Li Chi Liu Shanshan Zhang Haiyan Xiao Chunmei Zheng Shu Xu Rou Ma 2012Journal of Traditional Chinese Medicine2012,32,4:3
