Objective To diagnose the first imported case of Plasmodium ovale infection by laboratory detection. Meth?ods The epidemiological data and blood samples of the case were collected,and the samples were detected by the microscopic examination,rapid diagnostic test(RDT)and nested PCR. Results The patient was a construction worker backing from Con?go,Africa. He experienced the symptoms of irregular fever and weakness one month after returning in Lingyang Town,Junxian County. The results of RDT only suggested no?Plasmodium falciparum infection. Under the microscope,it was seen that the in?fected RBC were obviously disfigured and in irregular shape,the ring forms were thick and big,and also thick granulas in big trophozoite stage and schizont stage were found. The results of PCR showed that the size of amplified product was about 800 bp, which was conformed to that of P. ovale. Conclusion Though microscopic examination is the golden standard for malaria diag?nosis,as P. ovale is difficult to be identified under microscope,the microscopic method combined with PCR test can be used for definite diagnosis.

Objective To investigate the variance levels of plasma soluble leukocyte differentiation antigens CD40 (sCD40) and soluble CD40 ligand (sCD40L) in preeclamptic patients with renal damage and its relationship. Methods A total of 63 pregnant women attended the Department of Obstetrics, Affiliated Hospital of Qingdao University Medical College between August 2008 and June 2010. In the present study included 28 pregnant women with mild preeclampsia and 35 patients with severe preeclampsia. Thirty matched normotensive pregnant women were enrolled in the study as the control group. Expression of sCD40 and sCD40L were determined by ELISA. At the same time, the blood routine, C reaction protein ( CRP),urine routine, 24 hours urine protein excretion, and serum uric acid (UA), creatinine (Cr), blood urea nitrogen (BUN) were measured. The correlation analysis was performed between the sCD40/sCD40L and the blood biochemical indexes in 3 groups. Results ( 1 ) The median levels of CRP in severe preeclampsia (10. 8 mg/L)and mild preeclampsia group(7. I mg/L)are significantly higher than that of control group (3. 3 mg/L,P < 0. 05 ); The level of CRP in severe preeclampsia group was also higher than that of mild preeclampsia group ( P < 0. 05 ). The median gestational age at delivery in severe preeclampsia ( 32. 5 weeks)was significantly less than that of mild preeclampsia group ( 37. 2 weeks) and normal group ( 38. 6 weeks,P < 0. 05). However no significant differences were observed between mild preeclampsia group and normal group ( P >0. 05 ). The platelet count in severe preeclampsia ( 132 × 109/L) was significantly less than those of mild preeclampsia group (212 × 109/L) and normal group ( 216 × 109/L, P < 0. 01 ), but no significant differences were observed in blood platelet amount between mild preeclampsia group and normal group ( P >0. 05 ). There was no significant difference in hemoglobin level and white blood cell in three groups ( P >0. 05). (2) The sCD40 plasma concentration in severe, mild preeclampsia and normal group was 133.6,126. 5 and 90. 7 ng/L, respectively. The sCD40 L plasma concentrations were 12. 5, 10. 4 and 4. 4 ng/L respectively in the 3 groups. 24 hours urinary protein quantitative was 4. 5 g/d,0. 8 g/d and 0 in the 3 groups respectively. And the UA level was 486 μ mol/L,289 μmol/L and 162 μmol/L. In the above three groups,the monitoring indicators were significantly higher in women with severe preeclampsia group compared with mild preeclampsia and control groups (P < 0. 01 ), and there were also higher in mild preeclampsia group than that in control groups ( P < 0. 01 ). The level of plasma Cr ( 89 μmol/L) and BUN ( 5. 32 mmol/L) in severe preeclampsia group were higher than those of mild preeclampsia group (66 μmol/L and 4. 49mmol/L) and control group ( 57 μmol/L and 3.32 mmol/L, P < 0. 05 ). There was no significant difference between mild preeclampsia group and normal group (P > 0. 05 ). (3) The correlation analysis indicated that the level of sCD40 has a positive correlation with 24 hours urinary protein quantitative( r = 0. 434, P < 0. 05 ),also significant positive correlation( r =0. 536,0. 528 ,P < 0. 01 ) between the level of sCD40 and UA or CRP in women with preeclampsia. There was no significant correlation between the level of sCD40 and systolic blood pressure, diastolic blood pressure, delivery gestational age, Cr, BUN, and platelet count(r =0. 135,0. 183, -0. 133,0. 190,0. 167, -0. 221 ,all P >0. 05 ). There were positive correlation between the level of sCD40L and 24 hours urine protein excretion, either UA or CRP( r =0. 591,0. 445,0. 539 ,all P <0. 01 ). No significant correlation was found between sCD40 L and systolic blood pressure, diastolic blood pressure,delivery gestational age, Cr, BUN, and platelet count( r =0. 178,0. 212, -0. 292,0. 144,0. 135, -0. 273,all P >0. 05). There was significant positive correlation between plasma sCD40 and sCD40L ( r =0. 707 ,P <0. 01 ). There was no relationship between the level of sCD40, sCD40L and the blood biochemical indexes in normotensive pregnant women ( P > 0. 05 ). Conclusions The plasma concentrations of sCD40 and sCD40 L are significantly higher in pregnant women with preeclampsia compared with the control, which may be involved in the development of preeclampsia and contribute to the kidney damage. The variance levels of sCD40 and sCD40L may be also related to the severity of preeclampsia.
