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 By surface-enhanced laser desorption / ionization time-of-flight mass spectrometry(SELDI-TOF-MS), the serum pmteomic fingerprints related with the changing of malignant tumor patients' serum glucose after chemotherapy was selected and constructed as an predictive model. Methods By SELDI-TOF-MS, the serum of 182 malignant tumor patients who had received chemotherapy were tested, and the pmteomic fingerprints were received. After 2 years follow-up, all the patients were divided into 3 groups: the euglycemia group(136 people), the carbohydrate tolerance abnormality group(27 people), and the diabetes mellitus group (19 people). The proteomic fingerprints were analyzed by Biomarker Wizard Software and the idio-proteomic fingerprint of protective models were constructed by BPS (biomarker pattern software). Results The diagnosis model composed with 2 proteins (M/Z values were 5298 and 9608) could classify the carbohydrate tolerance abnormality group, and the diabetes mellitus group correctly. In the test model, the sensitivity and specificity were 81.48 %(22/27) and 100.00 %(17/17) respectively, the accuracy was 88.64 % (39/44). The diagnosis model composed with 3 proteins (M/Z values were 10324, 2761 and 4084) could classify the diabetes mellitus group and the euglycemia group correctly. In the test model, the sensitivity and specificity were 62.35 %(53/85) and 88.24 %(15/17) respectively, the accuracy was 66.67 %(68/102). The diagnosis model composed with 6 proteins (M/Z values were 5895,6010,6099,3930,5430 and 2495) could classify the diabetes mellitus group and the the carbohydrate tolerance abnormality group correctly. In the test model, the sensitivity and specificity were 77.65 %(66/85) and 96.30 %(26/27) respectively, the accuracy was 82.14 %(92/112). Conclusion SELDI-TOF-MS could be utilized to analyze protein profiling in screening serum glucose changing-related biomarkers and developing diagnostic and predictive patterns, and the developed patterns may be used to predict the changing of serum glucose after chemotherapy in malignant tumor patients.

Objective To investigate the indications and clinical efficacy of an exclusive right-thoracic approach in esophageal surgery.Methods The clinical data of 35 patients with esophageal disease who underwent an exclusive right-thoracic approach operation from June 2008 to June 2010 at the Affiliated Hospital of Qingdao University were retrospectively analyzed.Of the 35 patients,21 were with esophageal cancer,and their ages were above 70 years,the partial pressure of oxygen of arterial blood (PaO2),maximal voluntary ventilation and forced vital capacity of the first second were (70 ± 9) mm Hg (1 mm Hg =0.133 kPa),51％ ± 9％ and 57％ ± 11％,respectively.Fourteen patients were with benign esophageal disease or low grade malignancy,and their PaO2 maximal voluntary ventilation and forced vital capacity of the first second were (96 ± 13) mm Hg,83％ ± 11％ and 91％± 14％,respectively.Exclusive right-thoracic approach was selected for all the patients,and surgical procedure was selected according to the location of the lesions.Patients were followed up by out-patient examination or phone call till April 2012.Results All the operations were carried out successfully,21 patients with esophageal cancer underwent partial esophagus resection and stomach-esophagus intrathoracic anastomosis through a right-thoracic approach.Of the 14 patients with benign esophageal disease or low grade malignancy,2 patients were with esophageal leiomyoma,3 with esophageal stromal tumor and 1 with esophageal leiomyomatosis underwent partial esophagus resection + intrathoracic anastomosis ; 7 patients with esophageal leiomyoma and 1 with esophageal stromal tumor underwent tumor extirpation.The operation time and operative blood loss were (3.4 ± 1.8)hours and (160 ± 44)ml,respectively.The number of lymph node dissected of the 21 patients with esophageal tumor was 14 ± 5,including 1.1 ± 0.7 lymph nodes dissected near the left gastric artery.No anastomosis fistula and perioperative death were detected,and the duration of hospital stay was (10 ± 4)days.The postoperative PaO2,maximal voluntary ventilation and forced vital capacity of the first second were (66 ± 10)mm Hg,50％± 11％ and 51％ ± 13％ for patients with esophageal cancer,and (94 ± 13) mm Hg,80％ ± 13％ and 87％ ± 16％ for patients with benign esophageal disease or low grade malignancy.All the patients were followed up for 1-2 years,no eating obstruction was detected,and the postoperative 1-and 2-year survival rate were 82.9％(29/35) and 77.1％ (27/35),respectively.Of the 8 patients with esophageal cancer who died postoperatively,1 died of cardiovascular diseases and 7 died of tumor recurrence and metastasis.Conclusion Exclusive rightthoracic appraoch could be used for patients with benign esophageal disease,low-grade malignancy and old esophageal cancer patients with poor pulmonary function.
