ABSTRACT
Objective:To explore the effect of triglyceride glucose(TyG) index, single nucleotide polymorphism of Toll-like receptor 4(TLR4) and NOD-like receptor thermal protein domain associated protein 3(NLRP3) genes, and its interaction on the risk of gout.Methods:A total of 315 male patients with gout and 499 men for health checkup at the same period were selected. General data were collected through questionnaires, and peripheral venous blood was collected for biochemical test. Three single nucleotide polymorphisms(SNPs) of NLRP3 and TLR4 were detected with multiplex ligase assay reaction, and logistic regression analysis was applied to compare the correlation between NLRP3 and TLR4 alleles and gout risk. The interaction of SNP and TyG index with gout was analyzed by generalized multi-factor dimensionality reduction(GMDR) model and logistic regression.Results:After adjusting for smoking, drinking, and other factors, the risk of gout increased by 61.1% for each standard deviation increase in TyG index. CC genotypes of rs10754558, rs10759932, and rs7525979 were high risk genotypes of gout in Han ethnicity. GMDR results showed significant differences in the interaction models of rs10754558-TyG index, rs7525979-TyG index, and rs10759932-TyG index between control group and gout group( P<0.05), suggesting an interaction between the three genotypes of SNPs selected and TyG index. Stratified analysis of the three selected SNPs and TyG index showed that after adjusting for age, smoking, and other factors, the high TyG index patients carrying C/C or C/G genotype at rs10754558 displayed an increased risk of gout compared with those carrying GG genotype and low TyG index( OR=2.127, P<0.05). Conclusion:The CC genotypes of rs10754558, rs10759932, and rs7525979 are high risk genotypes for gout in Han ethnicity. The interaction between rs10754558 and TyG index may increase the risk of gout development.
ABSTRACT
Objective:To investigate the risk factors of gout and establish a columnar graph model to predict the risk of gout development.Methods:A total of 1 032 Han Chinese men attending the Affiliated Hospital of Traditional Chinese Medicine of Xinjiang Medical University, People′s Hospital of Xinjiang Uygur Autonomous Region, and the First Affiliated Hospital of Xinjiang Medical University from 2018 to 2020 were selected as study subjects and divided into training set(722 cases)and validation set(310 cases)by simple random sampling method in the ratio of 7∶3. General information and biochemical indices of the subjects were collected. The collected information was used to assess the risk of gout prevalence. LASSO regression analysis of R Studio software was used to screen the best predictors, and was introduced to construct a column line graph model for predicting gout risk using receiver operating characteristic(ROC)curves, and the Hosmer-Lemeshow test was used to assess the discrimination and calibration of the column line graph model. Finally, decision curve analysis(DCA)was performed using the rmda program package to assess the clinical utility of the model in validation data.Results:Age, uric acid, body mass index, total cholesterol, and waist-to-hip ratio were risk factors for gout( P<0.05). The column line graph prediction model based on the above five independent risk factors had good discrimination(AUC value: 0.923 for training set validation and 0.922 for validation set validation)and accuracy(Hosmer-Lemeshow test: P>0.05 for validation set validation); decision curve analysis showed that the prediction model curve had clinical practical value. Conclusion:The nomogram model established by combining age, uric acid, body mass index, total cholesterol, and waist-to-hip ratio indicators can predict the risk of gout more accurately.

ABSTRACT
Objective:To investigate the clinical characteristics and prognosis of Epstein-Barr virus-related diseases in adults.Methods:The clinical data of 59 patients with Epstein-Barr virus-related diseases in Huashan Hospital, Fudan University, Shanghai from January 2017 to August 2019 were analyzed retrospectively. The clinical manifestations of patients with infectious mononucleosis (IM), chronic active Epstein-Barr virus infection (CAEBV) and lymphoma in patients were compared. Patients were divided into acute course group (IM) and chronic course group (CAEBV+ lymphoma), and the results of labratory indications (blood rontine, liver function, imflammatory indications, Epstein-Barr virus DNA, Epstein-Barr virus antibody and T lymphocyte) were compared between two groups. Statistical analysis was performed by Mann-Whitney U test, chi-square test or Fisher exact probability test. Results:Among the 59 patients, 23 cases (39.0%) were diagnosed with IM, 23 cases (39.0%) were lymphoma and 13 cases (22.0%) were CAEBV. The clinical manifestations of patients with Epstein-Barr virus-related diseases were fever (57/59, 96.6%), lymphadenopathy (37/59, 62.7%) and splenomegaly (36/59, 61.0%). There were 17 patients in the chronic course group experienced hemophagocytic lymphohistiocytosis (HLH). The white blood cell counts, hemoglobin levels and platelet counts of patients in the chronic course group (4.07(1.94, 8.35)×10 9/L, 89.5(74.5, 108.0) g/L and 100(37, 161)×10 9/L, respectively) were all lower than those in the acute course group (9.91(6.75, 17.38)×10 9/L, 132.5(118.2, 152.0) g/L and 197(129, 233)×10 9/L, respectively), with statistically significant differences ( U=3.69, 5.22 and 3.61, respectively, all P<0.01). The levels of procalcitonin, C-reactive protein and serum ferritin in the chronic course group (0.45(0.15, 1.13) μg/L, 47.75(17.57, 84.67) mg/L and 2 000(682, 2 002) μg/L, respectively) were all higher than those in the acute course group (0.12(0.07, 0.28) μg/L, 6.39(3.13, 11.38) mg/L and 482(159, 1 271) μg/L, respectively), with statistically significant differences ( U=-2.95, -3.77 and -4.16, respectively, all P<0.01). The counts of CD4 + T lymphocytes, CD8 + T lymphocytes, CD19 + B lymphocytes and natural killer cells in the chronic course group (259.15(101.98, 509.26), 214.69(119.31, 529.47), 46.14(4.44, 135.87) and 81.09(41.53, 118.46)/μL, respectively) were all lower than those in the acute course group (738.88(592.20, 893.94), 1 609.17(920.88, 3 952.34), 144.52(83.65, 215.14) and 309.82(123.78, 590.68)/μL, respectively), with statistically significant differences ( U=3.66, 3.80, 2.90 and 3.40, respectively, all P<0.01), while the CD4 + /CD8 + T lymphocytes ratio in the chronic course group was higher (0.90(0.60, 1.70) vs 0.45(0.10, 1.28))( U=-2.29, P=0.02). Twenty-three patients with IM were all cured, while 10 patients with lymphoma died and 13 received chemotherapy. Seven patients with CAEBV died and six improved. Conclusions:The clinical characteristics of Epstein-Barr virus-related diseases in adults are fever, lymphadenectasis, splenomegaly.Chronic Epstein-Barr virus infection may be associated with HLH. The prognosis of adults with acute Epstein-Barr virus infection is good, while that of long-term chronic Epstein-Barr virus infection is poor.
ABSTRACT
Objective:To investigate the clinical characteristics and prognosis of cytomegalovirus (CMV) reactivation in patients with liver failure.Methods:A total of 75 patients diagnosed with liver failure and tested for serum CMV DNA between January 2016 and June 2019 in Huashan Hospital, Fudan University were retrospectively analyzed. According to the CMV DNA test results, the patients were divided into CMV DNA positive group and CMV DNA negative group. The classification of liver failure, the use of glucocorticoids, the proportions of T lymphocyte subsets of the two groups were compared and the prognosis was evaluated. Mann-Whitney U test and chi-square test were used to analyze the data. Results:Of the 75 patients with liver failure, 17 were CMV DNA positive and 58 were CMV DNA negative. Among the 17 CMV DNA positive patients, nine were acute (subacute) liver failure, and 13 were treated with glucocorticoids, which were all significantly higher than those in the CMV negative group (20.7%(12/58) and 20.7%(12/58), respectively). The differences were both statistically significant ( χ2=6.70 and 18.40, respectively, both P<0.05). The proportions of CD3 + T lymphocytes and CD8 + T lymphocytes in the CMV DNA positive group were both higher than those in the CMV DNA negative group, and the proportions of CD4 + T lymphocytes, the ratio of CD4 + /CD8 + T lymphocytes and the proportion of B lymphocytes were all lower than those in the CMV DNA negative group. The differences were all statistically significant ( U=274.50, 165.50, 273.00, 185.00 and 189.00, respectively, all P<0.05). Acute (subacute) liver failure (odds ratio ( OR)=4.3, 95% confidence interval ( CI) 1.3-12.6) and glucocorticoid use ( OR=12.5, 95% CI 3.4-38.3) were risk factors for CMV reactivation in patients with liver failure. The disease improvement rate in the CMV DNA negative group was 56.9% (33/58), and five out of 17 patients improved in the CMV DNA positive group, with a statistically significant difference ( χ2=1.99, P=0.04). Conclusions:The use of glucocorticoids increases the risk of CMV reactivation in patients with liver failure, and CMV reactivation in patients with liver failure presents immune disorders which seriously affect their prognosis. Therefore, it is important to pay attention to CMV DNA monitoring in patients with liver failure using glucocorticoids.
ABSTRACT
Objective:To investigate the psychological stress and related factors of community medical staff in Shanghai during infectious public health emergencies.Methods:Random cluster sampling, questionnaires combining general demographic information, self-rating anxiety scale(SAS), self-rating depression scale(SDS)and yale-brown obsessive compulsive scale(YB)were administrated to investigate the psychological stress of medical staff from 20 community healthcare centers in 10 Shanghai districts.Results:A total of 696 valid questionnaires were collected. 17.36% of the staff had SAS scores exceeding the boundary value. Nurses, staff with per capita monthly family income<5 000 yuan, or with below-average family relations presented higher SAS scores. 28.19% of the staff had SDS scores exceeding the boundary value. Staff with 5-10 years seniority, nurses, with per capita monthly family income<5 000 yuan, and with poor family relations presented higher SDS scores. 6.68% of the staff had YB score≥16. Nurses presented a higher YB score.Conclusions:Some community healthcare center staff experienced psychological stress during public health emergencies.Factors associated with psychological stress, such as 5-10 years′ seniority, nurses, per capita monthly family income<5 000 yuan, below-average or poor family relations, deserve more attention in order to prevent from or alleviate harmful psychological stress.

ABSTRACT
Objective@#To evaluate the efficacy and safety of oseltamivir in the treatment of suspected influenza in children.@*Method@#A multicenter, randomized and open-label trial was conducted among 229 individuals with suspected influenza which were collected from the clinic of 5 hospitals in Guangdong province (Guangzhou Women and Children′s Medical Center, Shenzhen Baoan District Maternity and Child Care Service Center, the Second Affiliated Hospital of Shantou University Medical College, Dongguan Maternity and Child Care Service Centre, Yuexiu District Children′s Hospital of Guangzhou) from April to July 2015. They were randomized either to oseltamivir group (oseltamivir 30-75 mg, twice daily for 5 days) or control group who were given symptom relief medicines for 5 days.@*Result@#No significant difference was found between two groups in influenza symptoms of the patients before the treatment(P>0.05). Altogether 229 individuals (114 in oseltamivir group, 115 in control group) were analyzed for efficacy, in which 73 individuals (42 oseltamivir, 31 control), 31.9%, were identified as influenza-infected through laboratory test. No significant difference was found between the two groups in the duration of fever although shortened. In the 229 individuals , the cumulative alleviation proportion between oseltamivir and control group was not significantly different (P>0.05): the median duration of illness was 69.9 hours (95% CI 65.3-91.5) in oseltamivir group and 75.4 hours (95%CI 63.9-91. 7) in control group; the median duration of fever was 40.4 hours (95%CI 31.5-53.4) in oseltamivir group and 44.0 hours (95%CI 33.2-50.0) in control group. In the 73 individuals, the cumulative alleviation proportion between oseltamivir and control group was significantly different (P<0.05). The median duration of illness was 61.2 hours (95%CI 48.0-121. 0) in oseltamivir group, being significantly shorter than that of 116.0 hours (95%CI 91.5-175.0) in control group. But it was not significantly different that the median duration of fever was 32.8 hours (95%CI 24.0-47.0 ) in oseltamivir group and 55.8 hours (95%CI 43.6-78.3 ) in control group (P>0.05). And the median duration of fever in 60 individuals (38 oseltamivir, 22 control) was significantly different between two groups(P<0.05), who had finished a course of taking oseltamivir in the 73 individuals, 34.8 hours (95%CI 24.0-48.5 ) in oseltamivir group being significantly shorter than that of 53.3 hours (95%CI 43.6-104.0 ) in control group. There was certain difference in side effects rate between the two groups (oseltamivir 10%, control 2%, P<0.05). The main side-effects were gastrointestinal symptoms (stomachache, diarrhea, poor appetite, vomiting).@*Conclusion@#The duration of illness and fever in suspected influenza patients treated with oseltamivir was shorter than those in the patients treated with no oseltamivir, the difference was not statistically significant, when 31.9% was confirmed with positive result of virus test in suspected influenza in children. But in these patients with positive result of virus test, the duration of illness was significantly shortened with treatment with oseltamivir as compared with no treatment with oseltamivir, and it would be better if full oseltamivir course was completed for reducing the duration of fever. Oseltamivir treatment was safe with mild side effects.
ABSTRACT
Objective:To analyze the level and related factors of burden of care,quality of life in family members of patients with schizophrenia.Methods:Totally 312 family members of patients with schizophrenia in 5 blocks of Jing'an District,Shanghai,who consented the investigation,were investigated.Burden of care were evaluated with the Zarit Caregiver Burden Interview (ZBI),and quality of life of the relatives by World Health Organization Quality of Life BREF (WHOQOL-BREF) and Chinese Residents SWB abridged (SWBS-CC20).ZBI score equal or higher than 39 indicated a heavy burden of care,while the score less than 39 indicated a low burden of care.Results:Totally 199 cases (63.8％) were in a heavy burden,whose ZBI score was (52.1 ± 10.8),and 113 cases (36.2％) were in a low burden with a mean score of (23.1 ± 10.4).Their WHOQOL-BREF score and SWBS-CC20 score were lower than normal model (Ps ＜ 0.001).The burden was heavy to those whose spouse was involved (β =-7.76).Patient's age was negatively correlated with quality of life (β3 =-0.18).Relationship with the patient,education level and monthly family income were positively correlated with quality of life (β =1.65,1.68,1.66).Conclusion:Those families of patients with schizophrenia,who are aged,low educated,low paid,or whose spouse have been diagnosed with schizophrenia,may have a heavy burden of care,and low quality of life.
ABSTRACT
Objective To study the correlation between the mental health of family members of patients with schizophrenia and their coping style. Methods From December, 2014 to January, 2015, a total of 312 family members of patients with schizophrenia in 5 blocks were included. They were surveyed with self-made questionnaire, Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS) and Simplified Coping Style Questionnaire. The results were compared with the national normal model, and the correlation between SDS, SAS and the coping style was also analyzed. Results Compared with the normal model, the SDS (t=34.39, P<0.001), SAS (t=73.09, P<0.001) scores were higher in schizophrenia families, and they used positive coping style (n=128, 41%) less (t=-16.70, P<0.001), and more often used negative coping style (n=184, 59%) (t=-66.24, P<0.001). The SDS (r=-0.14, P<0.05), SAS (r=-0.15, P=0.01) scores were negatively correlated with positive coping style, the SAS score was positively correlated with negative coping style (r=0.27, P<0.001). Multivariate Lo-gistic regression analysis showed that women were prone to be anxiety and depressed compared with men (P<0.05); the divorcees were prone to be depressed compared with thoses not divorced. Education level and average monthly household income were factors influencing their coping style (P<0.05). Conclusion The mental health of family members of patients with schizophrenia is not optimistic, the female family members are more likely to be depressed and anxious than males. People with low education level and poor economic conditions more often use negative coping style, which need to be focused on, and to take appropriate and effective intervention.
ABSTRACT
Objective To investigate the prevalence of nonalcoholic fatty liver disease (NAFLD) and understand the relationship between NAFLD and metabolic risk factors in middle-aged and elderly adults.Methods This cross-sectional study recruited 2 935 subjects in Guangzhou,Guangdong province.Face-to-face interviews and laboratory analyses were conducted to collect general information and other covariates.Analysis of covariance and logistic regression analysis were performed to investigate the relationship between metabolic factors and the prevalence of NAFLD.NAFLD was diagnosed based on standard criteria recommend by the Fatty Liver Disease and Alcoholic Liver Disease Branch of Chinese Hepatology Society,and the degree of steatosis was assessed (mild,moderate or severe).Results Compared with normal subjects,those with NAFLD had higher levels of WC,BMI,FPG,TG,SBP,DBP and greater prevalence of metabolic syndrome,but lower levels of physical activity and HDL-C.After adjusted for covariates,the OR for each standard deviation change was 2.70(95％CI:2.45-2.98) for WC,1.47(95％ CI:1.35-1.59) for SBP,1.48 (95％CI:1.37-1.60) for DBP,1.88 (95％CI:1.66-2.12) for TG,1.25 (95％ CI:1.15-1.36) for FPG and 0.51 (95％CI:0.47-0.56) for HDL-C (all P＜0.001).Higher levels of WC,BMI,TG,SBP,DBP and FPG were significantly related with the increase in degree of NAFLD (P-trend＜0.001).Conclusion There is a relatively high prevalence of NAFLD in middle-aged and elderly adults in China.NAFLD is closely related with the different forms of metabolic syndrome,and WC is the leading risk factor for NAFLD.
ABSTRACT
Objective To explore the short term treatment effectiveness and the side-effect of radiotherapy combined with two kinds of chemotherapy scheme on nasopharyngeal carcinoma patients with stage Ⅲ and Ⅳa.Methods One hundred and fifty nasopharyngeal carcinoma cases with stage Ⅲ/Ⅳa were randomly divided into A and B group.Patients in A group (75 cases) were received radiotherapy combined with 2 courses ((21-28) d/course) paclitaxel (135 mg/m2) + cis-platinum complexes (DDP) 80 mg/m2 chemotherapy concurrently,while patients in B group (75 cases) were received radiotherapy combined with 6 courses DDP 30 mg/m2 per week chemotherapy concurently.The short term treatment effectiveness and the sideeffect of radiotherapy combined with two kinds of chemotherapy scheme were observed.Result After the treatment,the primary lesion complete remission(CR) rate in A group and B group were 68％ (51/75),52％ (39/75).The CR rate of lymph node of neck in A and B group was 64.0％ (48/75),48.0％ (36/75) and 45.3％ (34/75),20.0％ (15/75) of primary lesion and lymph node of neck.The differences were significant(x2=4.25,3.90,10.94 ;P ＜0.05).After 3 months of treatment,there was no significant difference between A and B group in terms of CR rate of the primary lesion,lymph node of neck and primary lesion and lymph node of neck (P ＞0.05).During the treatment,the rate of bone marrow depression at grade Ⅲ in A group and B group were 38.67％ (29/75) and 21.33％ (16/75),21.33％ (16/75) and 6.67％ (5/75) in terms of the rate of grade gastrointestinal reaction at stage Ⅲ,46.66％ (35/75) and 21.33％ (16/75) regarding of oral cavity mucomembranous injury at stage Ⅲ,21.33％ (16/75) and 9.34％ (7/75) in terms of the rate of radioactivity skin destruction at stage Ⅲ.All differences were significant (P ＜ 0.05).During the short-term follow up (1-3 years),both the rate of local recurrence and the rate of metastasis in A group was as same as that in B group(P ＞0.05).Conclusion During the treatment,the side-effect of approach of paclitaxel (135 mg/m2) + DDP 80 mg/m2 in stage Ⅲ/Ⅳa nasopharyngeal carcinoma patients is more severity than that of DDP 30 mg/m2 per week chemotherapy.However,there is no significant difference in terms of the short term treatment effectiveness.The prospective efficacy needs to be further investigation.

The relationship between the serum TM level ,dose-volume factors with ARP was analyzed .Results 20 cases (37% ) had ARP .12 cases got grade 2 ARP and 8 cases had grade 3 .The occurrence rates of ARP in the minimal lethal dose (MLD) Gy 10 groups ,V5 < 50% and ≥ 50% groups ,V10 < 40% and ≥ 40% groups ,V20 < 25% and ≥ 25% groups ,V30 < 13% and ≥ 13%groups ,TM decrease group and TM increase group after 30 Gy radiation were 8% vs .62% ,7% vs .69% ,21% vs .75% ,28% vs . 56% ,15% vs .57% and 50% vs .13% respectively ,the differences had statistical significance (χ2 = 16 .83 ,22 .29 ,14 .05 ,3 .97 , 10 .08 ,6 .46 ,P<0 .05);in the ARP group and non-ARP group ,MLD ,V5 ,V10 ,V20 and V30 were (12 ± 2) vs .(9 ± 2) ,(58 ± 10) vs .(43 ± 10) ,(42 ± 8) vs .(30 ± 8) ,(23 ± 3) vs .(19 ± 6) ,(15 ± 4) vs .(11 ± 4) respectively ,the differences had statistical signifi-cance (t= -4 .96 ,-5 .27 ,-5 .70 ,-3 .37 ,-3 .61 ,P<0 .05) .Conclusion Multiple dose-volume parameters are associated with the occurrence rate of ARP .The patients with decreased serum TM level after radiotherapy are liable to develop ARP .
ABSTRACT
Objective To explore the curative effect of the operation of double wedge osteotomy of the first metatarsal for correction of severe hallux valgus.Methods The data of 62 patients (87 feet) with severe hallux valgus caused by enlarged distal metatarsal articular angle (DMAA) who were followed up after receiving the treatment of double wedge osteotomy of the first metatarsal from January 2008 to December 2011 were analyzed retrospectively.There are 9 males (14 feet),and 53 females (73 feet),with an average age of 56 years (range,28-70 years).Preoperative radiographs showed hallux valgus angle (HVA) was 48.6° in average,intermetatarsal angle (IMA) was 19.8° in average,and DMAA was 22.1° in avcragc.Thc opcration plan was made based on the preoperative deformity,and the osteotomy site,the angle,the capacity of osteotomy was all based on preoperative measurement.Compare the changes of HVA,IMA,DMAA before and after operation.The changes were also compared before and after the internal fixation extraction.The curative effect was observation based on American Orthopaedic Foot and Ankle Society (AOFAS) propodium score standard.Results Sixty-two patients (87 feet) were followed up for 10 to 57 months,with an average of 21 months.HVA (14.6°±1.2°),IMA (7.9°±0.7°),DMAA (7.7°±0.9°) were all satisfied 6 months after the operation.Stiff occurred in 2 patients after the operation.Cutaneous nerve injury occurred in 2 patients,and metastatic metatarsalgia occurred in 1 patient.No sever recurrence of deformity,bone nonunion and bone necrosis was found in all the patients.AOFAS score reached 91.8±1.8 one year after the operation,which was 28.4±9.1 preoperatively.Among them,49 feet were rated as excellent,31 as good,and 7 as fair.The excellent and good rate was 92％ (80/87).Conclusion The first metatarsal double osteotomy can effectively correct the severe hallux valgus deformity with enlarged DMAA with few complications.It achieves good effect.Patients can bear part of the loading in the early stage of recovery after operation.
ABSTRACT
ObjectiveTo investigate the association of BANK1 single nucleotide polymorphisms (SNPs) with rheumatoid arthritis(RA) in Chinese Han. MethodsTwo hundreds and twenty-one RA patients and 310 healthy controls who were Chinses Han population from Huashan Hopital and Changzheng Hospital in Shanghai,China were included.DNAs were extracted from peripheral whole blood for study.Samples were genotyped for three variants rs10516487,rs17266594 and rs3733197 in BANK1 by unlabelled probe high resolution melting (HRM) assay.The genotype frequencies of the detected polymorphisms were analyzed in relation to RA and the production of autoantibodies in RA patients.ResultsThe Tr genotype frequency was much higher in RA patients than in healthy controls(X2=6.241,P=0.044).The frequencies of rs10516487 G allele,rs17266594 T allele and rs3733197 G allele were increased among RA patients compared with healthy controls,although they didn't reach statistical significance.The rs10516487 and rs17266594 were found in strong linkage disequilibrium(D'=0.993,r2=0.985).And also the major TGG haplotype of 3-SNP was significantly associated with RA patients[P=0.037,OR =1.345,95％CI (1.018-1.776)].ConclusionBANK1 rs17266594 polymorphism is susceptible to RA,while rs10516487 and rs17266594 are linked in Chinese Han population.BANK1 SNPs TGG haplotype may contribute to RA susceptibility,too.
ABSTRACT
ObjectiveTo establish a simple and sensitive method to detect MPL515 mutations in peripheral blood of ET and PMF patients,and investigate the frequencies of the MPL515 and JAK2V617F mutations in Chinese patients.MethodsTotallv 261 patients of ET and 25 PMF cases were collected from Huashan Hospital of Fudan University and DNA samples were isolated from peripheral blood of these cases.SYBR GreenⅠreal-time PCR was used to detect JAK2V617F mutation.Taqman probe was designed to be specific for the three types of mutations ( MPl515wt,MPLW515L and MPIW515K).Real-time PCR was used to detect MPL515 mutations.Tbe results were confirmed by sequencing after T-A cloning.Results Among 261 ET patients,119 cases (45.6％ ) were identified as JAK2V617F mutation carriers and 7 cases (2.7％ ) were detected to be MPl515 mutation carriers,including 5 cases with MPLW515L,1 case with MPLW515K and 1 ease with MPLW515L + K.Additionally 10 cases with JAK2V617F(40.0％ ) and 3 cases with MPL515 ( 12.0％ ) were screened out in 25 PMF patients,including 1 case with MPLW515L and 2 cases with MPLW515L + K.One ET patient was found to harbor concurrent JAK2V617F and MPL515 mutations.ConclusionJAK2V617F mutation is the major molecular marker of ET and PMF,meanwhile MPL515 mutation is important and useful complement.
