Objective To investigate the clinical significance of peripheral blood parameters including immature reticulocyte fraction (IRF) in monitoring the hematopoietic recovery of patients with acute myeloid leukemia aftcr receiving consolidation chemotherapy with high dose cytarabine (HDAC).Methods The peripheral blood parameters,including absolute neutrophil (ANC) and platelet (Plt) counts as well as IRF,were measured by Sysmex XE-2100 automated hematology analyzer before and after consolidation chemotherapy with HDAC in 30 patients with acute myeloid leukemia.These peripheral blood parameters were further statistically analyzed and compared.Results Following consolidation chemotherapy,the median time to recovery for ANC,Plt and IRF was (9.2±2.5) days,(11.3±3.7) days and (5.0±2.6) days,respectively.In comparison with ANC and Plt recovery,IRF showed significantly early recovery (P ＜ 0.05).Additionally,ANC raised preceding Plt recovery (P ＜ 0.05).However,the median recovery time of ANC,Plt and IRF showed little difference among these patients further subgrouped according to FAB and risk based classification (P ＞ 0.05).Conclusion IRF is an early indicator for the hematopoietic recovery of patients with acute myeloid leukemia following consolidation chemotherapy with HDAC,which could provide important clinical information to evaluate therapeutic efficacy.

Objective To explore the levels of neuron-specific enolase(NSE)in serum and cerebrospinal fluid(CSF) of children with convulsion,and its significance to the diagnosis of neuronal damage was evaluated.Methods Sixty patients were enrolled,and they were divided into 4 groups:non-nervous system disease group,peripheral nervous system disease group,brief convulsion group,and prolonged/status convulsion group.The levels of NSE in serum and CSF were detected in 4 groups,and the electroencephalography(EEG) and computed tomography/magnetic resonance imaging(CT/MRI) examinations were taken to observe the changes in patients with convulsion.Results The levels of NSE in serum and CSF of children with convulsion increased significant,especially in the prolonged/status convulsion group.Changes of NSE levels in serum and CSF were similar.Meanwhile,significant changes were found in EEG between the brief convulsion group and prolonged/status convulsion group;but no significantly changes were found in CT/MRI between the 2 groups.Conclusions NSE detection might be valuable to the diagnosis for neuronal damage in early time.The changes of NSE levels are similar to those in EEG,which are more sensitive than the changes in CT/MRI.It is very important to combine the NSE detection in serum or CSF and EEG examination in early time after convulsion for judgement to the neuronal damage and prognosis.

Objective To evaluate the efficacy and safety of early anticoagulation therapy using low-molecular-weight heparin sodium against venous thromboembolism (VTE) in traumatic patients.Methods A total of 120 severely traumatized patients were assigned to convention group (n =60) and anticoagulation group (n =60) according to the random number table.Patients in convention group were given physical therapy against VTE,while in anticoagulation group were given add-on low-molecularweight heparin sodium against VTE once the stopping of blood bleeding was achieved.Safety parameters were recorded including VTE incidence,blood loss indexes,hemorrhage-related complications,incidence of heparin-induced thrombopenia (HIT) and blood coagulation function indicators.Results Thirteen patients presented with VTE,with 10 patients (17％) in convention group versus 3 patients 5％) in anticoagulation group (P ＜ 0.05).Blood loss index in convention group was 1.252 ± 1.033 versus 1.447 ± 1.196 in anticoagulation group;two patients (3％) developed gastrointestinal bleeding in convention group versus five patients (8％) in anticoagulation group;five patients (8％) had wound bleeding in convention group versus eight patients (13％) in anticoagulation group (all P ＞ 0.05).HIT was not noted in anticoagulation group.At the endpoint of evaluation,no significant differences were noted between the two groups with regard to changes in prothrombin time (PT),activated partial thromboplastin time (APTT) and D-dimers (P ＞ 0.05);however,convention group versus anticoagulation group showed significant differences in international normalized ratio (INR) (0.97 ± 0.10 vs.1.03 ±0.17),fibrin (Fib) [(4.85-± 1.37) g/L vs.(4.01 ± 1.16) g/L] and platelet (PLT) [(317.68 ±141.71) ×109/Lvs.(422.20±178.16) ×109/L] (P＜0.05).Conclusion Inthe earlystage of trauma,low-molecular-weight heparin anticoagulation therapy can significantly reduce the incidence of VTE without increasing the risk of bleeding.

Objective To develop the specific module of quality of life instrument for patients with esophageal cancer. Methods with the structured group ( nominal group and focus group) methods and the qualitative and quantitative theory and methodology in developing rating scales, items were preliminary screened, evaluated and modified. And the data measuring from 28 cases of esophageal cancer patients and 25 doctors/nurses were analyzed by 4 statistical procedures: method of coefficient of variation, correlation analysis, patients'importance rating procedure and doctors' importance rating procedure. Results By above statistical procedures and advises of doctors, thus 19 - items specific module was formed finally. Conclusions The specific module developed on the strict procedures has good content representativeness and validity.

Objective To investigate the distribution features and antibiotic drug resistance of infection pathogens isolated from elderly patients with malignancies complicated with infection following treatment in an open hematology ward.Methods From January 2010 to June 2012,specimens from hospitalized elderly patients with concurrent infection were cultured to isolate infection pathogens through routine methods.Antimicrobial susceptibility tests were performed by the microdilution method.Results A total of 302 strains of infection pathogens were isolated from all detected samples,among which isolated strains of Gram-positive bacteria,Gram-negative bacteria and fungi were 91,194 and 17 strains,respectively.Isolated fungi were mostly susceptible to antifungal drugs.Gram-negative bacteria were highly susceptible to carbapenem,while Gram-positive bacteria were most sensitive to vancomycin and teicoplanin.Conclnsion The nosocomial infection pathogens of elderly patients with malignancies in hematology ward are most likely Gram-negative bacteria.Before specimens culture results and susceptibility are known,all these patients should be empirically treated with broad spectrum antibiotics,which have the most activity against Gram-negative bacteria as well as Gram-positive bacteria coverage.

Objective To compare the caesarean scar pregnancy abdominal ultrasound,transvaginal ultra-sound and abdominal combined transvaginal ultrasound ultrasonic imaging features and diagnostic results,to explore the diagnosis value of different methods.Methods All 22 case with cesarean scar pregnancy ultrasound through three ways were selected,and the ultrasonic features and diagnostic rate of different methods were compared.Results Abdominal ultrasound diagnosis rate was 40.91%,transvaginal ultrasound diagnosis rate was 81.82%,combining ultrasound diagnosis rate was 95.45%,and the three methods of inspection diagnosis rate differences were statistically significant(χ2 =17.88,P <0.05).Conclusion Transvaginal ultrasound in the diagnosis of cesarean scar pregnancy has important value,combining ultrasound examination can further improve the diagnosis rate.

Objective To explore the application of self-made guided wire operating-tray,which is designed for percutaneous tranluminal coronary angioplasty (PTCA),in performing coronary intervention (PCI).Methods A total of 40 patients who were planned to receive PCI were randomly divided into the study group (n=20,using guided wire operating-tray) and the control group (n=20,using traditional method to operate guide wire).Under local anesthesia PCI was carried out in all patients of both groups.The frequency of guide wire winding,the degree of surgical sheet contamination within the operation area,and the comfort and convenience of operating guide wire were assessed,the results were compared between the two groups.Results The frequency of guide wire winding and the degree of surgical sheet contamination within operation area in the study group were remarkably lower than those in the control group (P＜0.05).The comfort and convenience of operating guide wire in the study group was better than that in the control group (P＜0.05).Conclusion In performing PCI,the use of self-made guided wire operating-tray can effectively avoid guide wire winding and reduce the degree of surgical sheet contamination within the operation area.

Objective The sensitivity and specificity of 18 FDG PET/CT are poor in the diagnosis of gastric cancer .Gastric signet ring cell carcinoma and Mucinous gastric carcinoma is known to have low fluorodeoxyglucose (18FDG) uptake,but not known for poorly differentiated gastric adenocarcinoma .This study was to investigate the value of 18 FDG PET/CT in the diagnosis of poorly differ-entiated gastric adenocarcinoma . Methods We retrospectively analyzed the results of 18 FDG PET/CT of 34 cases of histologically confirmed poorly differentiated gastric adenocarcinoma .We recorded the volume , location , and gastric wall invasion depth , and maxi-mum standardized uptake value ( SUVmax) of the tumors and analyzed the relationship of 18 FDG uptake with the clinicopathologic pa-rameters. Results By 18 FDG-PET/CT, poorly differentiated gastric adenocarcinoma was diagnosed in only 67.6% of the patients (23/34).SUVmax was found to be significantly correlated with age , gastric wall invasion, and tumor size (P<0.05), but not with gender , tumor location , tumor pathologic subtype , lymph node metastasis , and distant metastasis ( P>0 .05 ) .Logistic regression a-nalysis showed the tumor size to be the sole factor influencing the 18 FDG uptake of poorly differentiated gastric adenocarcinoma ( OR=0.37, 95%CI 0.154-0.920, P=0.03). Conclusion The di-agnostic value of 18 FDG-PET/CT is but limited for poorly differentia-ted gastric adenocarcinoma , and attention should be paid to its false-negative results .

Small for gestational age ( SGA ),one of the major adverse pregnancy outcomes, significantly increases the risk of perinatal death and metabolic diseases in adulthood. It is of great significance to strengthen early surveillance and intervention for SGA prevention. Dyslipidemia during pregnancy, as a common metabolic disorder, has been considered to correlate with the increased risk of SGA; however, the epidemiological evidence is still controversial. We have systematically reviewed the recent studies related to the association between serum lipid level during pregnancy and the risk of SGA, so as to provide reference for prevention and intervention of SGA.
