Since haemoplasmodium is not detected for screening in blood donor,morbidity of transfusion-associated malaria increased rapidly in China recently and became an important problem of public health.It is necessary to emphasize donor screening for malaria.Hematology analyzer with MAPSS is recommended to screen malaria.Flow cytometry and immunochromatography test(ICT)can also screen malaria effectively.For the suspicious samples with haemoplasmodium,it is necessary to be reexamined by standard microscopic examination or polymerase chain reaction(PCR).

Objective To evaluate the hematologic effects of linezolid in advanced aged patients with hospital onset of infection.Methods The clinical characteristics and complete blood routine examination results of 45 elderly patients aged(92.9±5.2)years treated with linezolid over 600 mg of lowest dose everyday for more than 72 hours were retrospectively analyzed.Results Among the 45patients,20 patients(44.4％)had substantially lower platelet,6 patients(13.3％)lower haemoglobin,1 patient(2.2％)lower absolute neutrophil,and the linezolid treatment in 19 patients were discontinued due to hematological system adverse reactions.The significant drop in platelet occurred at(10.2±3.3)days after treatment.The significant drop in hemoglobin occurred at(9.8±3.0)d after treatment.The lowest count of platelet and hemoglobin took place at(13.1±3.9)d and (10.5±3.5)d after treatment,respectively.The drops in platelet and hemoglobin of some patients took place after cease of treatment.Stepwise logistic regression analysis revealed that treatment duration(OR =1.407,P＜0.05)and creatinine clearance rate(OR=0.732,P＜0.05)were the risk factors for thrombocytopenia.Conclusions The elderly patients using linezolid more likely suffer from adverse reactions of hematological system,particularly thrombocytopeniawhich is significantly more common in patients with renal insufficiency and prolongation of treatment time.The blood routine examination should be monitored closely when elderly patients are treated with linezolid.

Objective To evaluate the clinical value of 99Tcm-MIBI SPECT for the differential diagnosis of parotid tumors before treatment.Methods 99Tcm-MIBI SPECT imaging of the parotid region was obtained in 32 patients with parotid tumors before surgery.Early and delayed 99Tcm-MIBI imaging were performed in all patients and the diagnosis was confirmed by pathological results after surgery.The ratio of radioactivity between the tumor and opposite side of normal parotid tissue (T/N) was measured.Fisher exact probability test and t test were used for statistical analysis.Results The sensitivity,specificity and accuracy of 99Tcm-MIBI SPECT imaging for the differential diagnosis of parotid tumor were 90.00％ (9/10),86.36％ (19/22) and 87.50％ (28/32),respectively.Among 22 patients who had benign tumors,19(86.36％) showed negative findings,and the other 3 ( 13.64％ ) patients showed false positive results.In 10 patients with malignant tumors,1 ( 10.00％ ) had false negative findings,and all the other 9 (90.00％)patients showed positive results.The difference between the benign and malignant groups was statistically significant (P =0.00018 ).In the early images,the T/N ratios of benign and malignant parotid tumors were 1.45 ±0.38 and 1.65 ±0.63 (t =20.4,P＜0.01),respectively; and in the delayed images,the ratios were 1.43 ± 0.56 and 1.77 ± 0.59 ( t =2.4,P ＜ 0.05 ),respectively.Conclusion 99Tcm-MIBI SPECT imaging might be useful for the differential diagnosis of parotid tumors before surgery.

Objective To study the effect of esomeprazole,clarithromycin,metronidazole triple therapy for helicobactor pylori(Hp) infection in children.Methods Ninty-eight cases of children,identified by ~ 13 C-urea breath test(~ 13 C-UBT) Hp infection,deparded into therapy group(66 cases) and control group(32 cases).Therapy group were given Esomeprazole[0.8 mg/(kg?d),1 time/d],clarithromycin[15 mg/(kg?d),2 times/d],metronidazole[30 mg/(kg?d),3 times/d]triple therapy.Control group were given the same treatment except ameprazole.The course was 1 week.They were followed up 4 weeks later after the course and re-tested by ~ 13 C-UBT.Results The recurrent abdominal pain of the two groups recovered in different degrees,and the efficacy rate was 100%.The eradication rate of Hp in therapy group and control group were separately 90.9%(60/66) and 87.5%(28/32).There was no significance difference of the eradication of Hp.Conclusions The trearment of esomeprazole,clarithromycin,metronidazole triple therapy on Hp infection in children is quite effective and safe.The side effect is moderate.
