Objective To explore the risk factors for intracranial hemorrhage caused by late vitamin K deficiency bleeding(VKDB),in order to prevent and reduce the incidence of intracranial hemorrhage caused by late VKDB.Methods A retrospective analysis of the risk factors of late VKDB and intracranial hemorrhage was applied to 2 groups of patients in PICU and department of neurology of Beijing children's Hospital from Jan.2002 to Dec.2007.In group Ⅰ,there were 90 patients suffering from intracranial hemorrhage caused by late VKDB;while in group Ⅱ,there were 23 patients of late VKDB without intracranial hemorrhage.Within 12 hours of hospitalization,the following 9 items were checked:the cranial CT,blood calcium concentration,liver function,serum sodium,blood glucose,prothrombin time,partial thromboplastin time,fibrinogen concentration,and platelet.Ten possible relevant risk factors of gender,age,birth situation,feeding patterns,recent diarrhea,cytomegalovirus(CMV)infection,hypocalcemia,dysglycemia,hyponatremia,and abnormal liver function were analyzed by the method of non-conditional Logistic regression analysis.Results Statistically significant difference had been found in the 3 factors of hypocalcaemia,recent diarrhea,abnormal liver function(Pa

ObjectiveTo explore the clinical and epidemiological value of semi-quantitative regional cerebral blood flow(rCBF)imaging in children with school phobia. Methods A total of 20 cases diagnosed with school phobia were examined with rCBF.Twelve were males and the other 8 were females.The mean age was(14.2?2.1)years(11-18 years).Semi-quantitative analysis methods were used to investigate the correlations among gender,age and rCBF. ResultsThere were significant differences in the rCBF of right fronto-parietal lobe,right occipital lobe,caput and putamen,left thalamus and hippocampus,and temporo-occipital lobe between males and females(P0.05).Only the PI of left temporo-parietal lobe of those ≥ 15 years old was significantly different from that of those

Objective To study the clinical characteristics and analyze the treatment of primary ocular adnexal lymphoma (POAL). Methods A retrospective review was performed based on the clinical records of 26 POAL cases, who were treated from June 1999 to June 2009. The clinical manifestations,imaging features, diagnosis approaches and treatment of them were analyzed. Results The main symptoms were a slowly growing painless mass, exophthalmia and red eyelid. Mostly, imaging finding shows casting like. 50 % of POAL was at the orbit. 22 patients w ere B-cell origin [13 patients were extranodal marginal zone B-cell lymphoma-mucosal-associated lymphoid tissue (MALT) lymphoma], 2 patients were NK/T cell lymphoma. 76.9 % patients were in stage Ⅰ -Ⅱ. Surgery, radiotherapy and chemotherapy were most common treatment modalities for POAL. Conclusion Most POAL were low-grade B-cell lymphoma, with MALT by far the most common type. POAL was easy to be misdiagnosed due to non specific clinical manifestations.Imaging finding was helpful to diagnosis, but could not reliably distinguish between benign and malignant. The invasive biopsy is the main diagnosis approach. Radiotherapy had been the standard treatment for low-grade POAL. High-grade or infiltrating peri-orbit need combine chemotherapy. lmmunotherapy and molecular targeted therapy were the direction of future research.

Objective To evaluate the efficacy and safety of fludarabine and pirarubicin (FT) regimen in the treatment of refractory or relapsed indolent non-Hodgkin lymphoma (NHL). Methods A total of 40 patients with relapsed or refractory indolent NHL were treated with FT regimen, one cycle for 28 days, total 6 cycles. The data of indolent NHL patients treated with fludarabine, noventrene and dexamethasone (FND) regimen were collected as control. Results 40 patients were given 228 cycles chemotherapy, overall response rate was 62.5 %, median progression-free survival was more than 20 months and 2 years overall survival rate was 70.0 %. The main toxicities was leucopenia (80.0 %), but the incidence of WHO Ⅲ-Ⅳ leucopenia and pneumonia was less than that of in the control group, the rate were 12.5 % vs 29.0 % and 2.5 % vs 23.0 % respectively (P <0.05). Conclusion The efficacy of FT regimen was as good as FND regimen, but the incidence of leucopenia and pneumonia by Ⅲ-Ⅳ was lower in FT group than in FND group. So the FT regimen was an effective and safe second-line salvage regimen for relapsed or refractory indolent non-Hodgkin lymphoma.

Objective To observe the therapeutic effects of Pegasys (pegylated interferon α-2a)in chronic hepatitis B (CHB) patients with low-level alanine transarninase (ALT) ＜ 2 × upper limit of normal (ULN).Methods One hundred and seven CHB patients were randomized enrolled including 52 with ALT ＜ 2 × ULN and liver tissues inflammation activity≥ G2 as observational group and 55 with ALT ＞ 2 × ULN as control group.All the enrolled patients received pegasys treatment for 48 weeks and the responses between two groups were compared.Measurement data were analyzed using t test and numeration data were analyzed using chi square test.Results The reductions of HBV DNA in observational group at different time points were all less than control group (all P ＜ 0.05).At the end of treatment,the HBV DNA negative rate,HBeAg seroconversion rate and HBsAg loss rate in the observational group were 51.9％,48.8％ and 1.9％,respectively,which were all lower than control group (67.3％,66.7％ and 7.3％,respectivley) (all P ＜ 0.05).The ALT normalization rates of two groups were 75％ and 76.4％ (P ＞ 0.05).Conclusion Pegasys is efficient for CHB patients with ALT ＜ 2 × ULN and liver tissues inflammation activity ≥ G2,while it is still inferior to those with ALT ＞ 2 × ULN.

OBJECTIVETo investigate the biological difference of clonal cells between myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML).

METHODBone marrow (BM) clonal cells (which had cytogenetic markers detected by FISH assay) and blasts were quantitatively analysed in 51 MDS and 11 AML patients. The clonal cell percentage in orthochromatic normoblasts, granulocytes and megakaryocytes were assayed. The biological functions for phagocytosis and oxidation of MDS peripheral blood (PB) neutrophils were compared with that of normal controls.

RESULTSAlmost all MDS patients BM had a higher clonal cell percentage (mean 48.2%) than blasts percentage (mean 6.7%) (P < 0.01), but with the subtype of MDS advancing this percentage gap was closing up, and in 11 AML patients no such gap was observed. This gap in MDS patients with + 8 abnormality was smaller than in those with 5q -. In MDS BM, clonal cells were detected in segmented granulocytes (mean 45.9%), orthochromatic normoblasts (mean 46.0%) and mature megakaryocytes (mean 38.0%). In Addition, an approximate amount of clonal cells with the same karyotype abnormality in BM were detected in MDS PB (mean 37.3% in blood vs 48.6% in marrow). Functional analysis showed that the neutrophils in MDS PB could exert nearly normal physiological functions (P > 0.05), but those from AML could not as compared to healthy donors (P < 0.01).

CONCLUSIONThere is a significant difference in the biological features between MDS and AML clonal cells.

Objective To analyze the choice of implant materials,key points of operative proce- dures,prevention and management of postoperative complications in patients treated with cranioplasty. Methods Two hundred and twenty six patients with craniocerebral trauma underwent cranioplasty with different implant materials.Attention should be paid for the purpose of not tearing or injuring the dura ma- ter during operation.To take the dura mater up to the implant material and the edge of the bone flap,and put drainage under the scalp flap before closure of the incision.Results The clinical symptoms and neural function were improved in 146(64.6%)patients postoperatively.Postoperative complications mainly were infection,fluid collection and hematoma in the operative region.Follow-up showed the occur- rence of displacement or collapse of the implant materials in some patients.Conclusion Timely cra- nioplasty can not only resolve cosmetic problems but also improve clinical symptoms and neural function. The causes of postoperative complications are mainly related with the operative procedures and the materi- als used.

Objective: To analyze the association between different sleep behaviors and overweight and obesity of junior high school students in Yangzhou City, and to provide a basis for policies and interventions related to adolescent health management. Methods: A total of 1 589 students in grades 7-9 from two middle schools in Yangzhou City were selected using the cluster sampling method and were administered with sleep time, bedtime, social jetlag difference, and sleep habits. Results: Totally 64.38% were sleep deprived during the school days, 86.78% went to bed too late, 46.51% had a social jetlag of ≥1 h, and 37.44% took a nap every day(Incluldes holidays and school days). Social jetlag length was statistically different between grades( F =6.97, P < 0.01 ). Girls[(0.95±0.65)h] shown significantly higher social jetlag than the boys[(0.76±0.59)h]( t=6.19, P <0.01). Later bedtime on weekends, later wake up time on weekends and poor sleep behavior were risk factors for overweight and obesity in junior high school students( OR=1.20, 1.14, 1.04, P <0.05). Conclusion Junior high school students had less sleep and later bedtimes with the increase of grade, and weekend bedtimes,wake up times and poor sleep behavior were independently associated with the risk of overweight and obesity in junior high school students. Parents and schools should be instructed to pay attention to their sleep health and carry out adolescent sleep health guidance.

OBJECTIVETo investigate and analyze the variation trends in the pathological composition of thyroid cancer patients treated in Tianjin Cancer Hospital from 1954 to 2009.

METHODSTo retrospectively analyze the incidence and clinical features of different pathological types of thyroid cancers in 4342 patients between different time periods from 1954 to 2009.

RESULTSIn the four main pathological types of thyroid cancers, the component ratio of papillary thyroid cancer in every period was 68.1%, 78.3%, 81.3%, 82.1%, 85.8%, respectively, while the morbidity of patients with papillary thyroid carcinoma concurrent with Hashimoto's thyroiditis was increased, so was the proportion of tumors in diameter < or = 2 cm. The proportion of follicular thyroid carcinoma and anaplastic thyroid carcinoma was decreasing accordingly; however, the proportion of medullary thyroid carcinoma did not change significantly.

CONCLUSIONSThe pathological classification of the thyroid carcinoma patients has significant changes in the 4342 cases treated in our Hospital from 1954 to 2009. The proportion of papillary carcinoma is increased, while that of follicular carcinoma and anaplastic carcinoma is decreased. The reasons might attribute to the improved level of consultations and iodized diet or other factors.
