Objective Using single direction dispersion breathless DWI, to analyze the value of DWI for vertebral bone marrow infiltration in patients with acute leukemia (AL). MethodsForty-two patients with AL and 15 healthy volunteers received vertebral sagittal DWI with single shot spin-echo echoplan imaging (SS-SE-EPI) sequence( b value ＝ 0,650 s/mm2) at a GE Signa Excite 1. 5 T scanner with 8 channels body coil. DWI for all patients were performed from three directions, including from superior to inferior (S/I), from anterior to posterior (A/P) and from right to left (R/L). The apparent diffusion coefficient (ADC) value was measured on ADC map from each direction using GE-Function tool DWI software. Forty two patients consisted of 13 onset with untreated patients and 29 treated patients (7 nonremission,8 complete remission and 14 consolidation therapy). The ADC values among the three diffusion directions were compared. Analysis of variance and t test were used to compare the ADC values in different AL stages, Pearson correlation analysis was used to analyze the correlation between ADC values and the percentage of bone marrow progenitor cells. Results The ADC values from S/I, A/P and R/L of 362 vertebras in the 57 subjects are (0. 758 ±0. 009) × 10-3 mm2/s, (0. 732 ±0. 009) × 10 -3 mm2/s and (0. 758 ±0. 009) × 10 -3 mm2/s, respectively. There is no statistical significance( F ＝ 2. 958, P ＞ 0. 05 ).The ADC values from S/I of 94 vertebras in 15 healthy volunteers is (0. 697 ± 0. 122) × 10 -3 mm2/s, of 85 vertebras in 13 untreated AL patients is (0. 592 ±0. 071 ) × 10-3mm2/s. There is statistical significance between them ( t ＝ 2. 568, P ＜ 0. 05 ) ; The ADC value of 183 vertebras in 29 treated AL patients [ ( 0. 796 ±0. 225 ) × 10-3mm2/s]is higher than that in untreated patients with statistical significance (t ＝ -1. 332,P ＜0. 05). One hundred and forty vertebras in patients with complete remission and consolidation therapy were [ (0. 786 ±0. 184) × 10-3 mm2/s],and 43 vertebras in patients with non-remission(NR) [ (0. 804 ±0. 327 ) × 10 - 3 mm2/s], there was not statistical significance between them ( t ＝ - 0. 160, P ＞ 0. 05 ). The ADC values from S/I direction of untreated patients showed significant negative correlation with the proportion of the blast cell in the bone marrow ( median value 26. 4％. Min 7.9％, Max 48. 2％ ) ( r ＝- 0. 524, P ＜ 0. 05 ). ConclusionsDWI of vertebral bone marrow is isotropy. ADC value is a non-invasive and quantitative index for evaluating the pathogenetic condition of AL.

Objective To investigate the clinical effect of ultrasound induction combined with acupunc-ture points and polyethylene glycol 4000 powder for treating constipation in elderly patients with hip fracture. Methods A randomized parallel controlled method was adopted.A total of 100 inpatients meeting the inclu-sion criteria were divided into the control group and treatment group.Fifty cases in the control group were given polyethylene glycol 4000 powder,10 g/d,taking at a draught in 1 h after lunch.Fifty cases in the treat-ment group adopted the ultrasound induction combined with Shenque acupoint and Guanyuan acupoint,which was implemented at 1 h after lunch every day,once a day,30 min each time,and the intensity was appropriate for the patients to tolerate.The two groups were continuously treated for 1 week.The clinical symptoms be-fore and after treatment in the two groups were observed.The constipation score,quality of life score,treat-ment efficacy and safety were compared between before and after treatment.Results There were 3 dropout cases in the control group and 47 cases were finally included.Among them,14 cases were excellently effective,20 cases were effective,13 cases were ineffective,and the total effective rate was 72.34％;there were 2 dropout cases in the treatment group and 48 cases were finally included.Among them,15 cases were excellently effec-tive,18 cases were effective,15 cases were ineffective,and the total effective rate was 68.75％;the total effec-tive rate had no statistical difference between the two groups (P>0.05).The effect onset time of the treat-ment group was earlier than that of the control group with statistical difference (P<0.05).The abdominal symptom dimension and total score in the constipation scores after treatment in the treatment group were lower than those in the control group,and the differences were statistically significant (P<0.05).After treat-ment,the physiological,satisfaction dimension scores and total score in life quality score in the treatment group were lower than those in the control group,and the differences were statistically significant (P<0.05). During the test process,2 cases in the control group had adverse drug reactions,which manifested by mild di-arrhea at the end of the treatment course,and no adverse reactions were found in the treatment group.Conclu-sion The ultrasound induction combined with acupuncture points for treating constipation in elderly patients with hip fracture has equivalence with polyethylene glycol 4000 powder,moreover which has the advantages in the aspects of effect onset time and improvement of abdominal symptoms.

Objective:To compare the test methods for aluminum content determination in vaccines by inductively coupled plasma-mass spectrometry(ICP-MS),inductively coupled plasma optical emission spectrometry(ICP-OES)and titration of the Chinese Pharmacopoeia 2020.Methods:The pre-treatment procedures,linearity,repeatability,accuracy,quantification limit,detection limit and sample determination results of the three methods were compared and analyzed by methodological verification and sample testing.Results:There was a good linear relationship of ICP-OES in the concentration range of 1-20μg·mL-1 aluminum content,r=0.9999.Aluminum content in 6 types of vaccines was in the range of 99％-104.6％,and RSDs were lower than 3％(n=9).There was a good linear relationship of ICP-MS in the concentration range of 2.5-80ng·mL-1(r=0.999).Aluminum content in 6 types of vaccines were in the range of 99.4％-108.9％,and RSDs were lower than 8％(n=9).There was no significant difference between the three methods in the determination of aluminum content in vaccines,and RSDs were lower than 10％.Conclusion:Both ICP-MS and ICP-OES methods can be used for the determination of alu-minum content in aluminum adjuvant vaccine.Both detection methods are simple,fast and accurate.ICP-OES has lower instrument costs and is easier to promote in the laboratory.

ObjectiveTo determine the prevalence of hepatitis C virus （HCV） infection and identify the underlying risk factors among drug users in Taizhou City of Zhejiang Province during 2009‒2020. MethodsA consecutive cross-sectional survey was conducted. A total of 400 drug users in correctional settings were randomly selected from April to August. The drug users were interviewed with a questionnaire to collect demographic characteristics， AIDS-related knowledge， detoxification service， drug use， and sexual behavior. Blood samples were then collected for anti-HCV antibody testing. Chi-square test and multivariate conditional logistic regression were used. ResultsA total of 5 042 drug users were included in this study. Seroprevalence of HCV was determined to be 22.7%. From 2009 to 2019， the seroprevalence showed a significant downward trend， from 34.9% to 8.8% （χ²=221.025， P<0.001）. However， in 2020， the seroprevalence was 12.7%. The multivariate logistic regression analysis showed that senior age （≥25 years old）， cohabitation， taking traditional or mixed drugs， injection drug use， and needle sharing were risk factors associated with HCV seroprevalence. ConclusionSince 2009， HCV seroprevalence among drug users in Taizhou City has shown a downward trend， however， it has increased slightly in 2020. It warrants strengthening prevention and treatment measures in response to risk factors related to HCV infection among drug users.
