Objective To obtain the molecular epidemiology of human Parechovirus (HPeV)infections m children with central nervous system (CNS)-related disease and sepsis,as well as understand the pathogenic properties of HPeV infections by detecting HPeV in cerebrospinal fluid (CSF) and blood samples.Methods From January to December in the year of 2009,a total of 359enterovirus-negative specimens including 210 CSF and 149 blood samples were collected from 328children <14 years of age who were hospitalized for CNS-related disease and sepsis at Children's Hospital,Fudan University,Shanghai,China.HPeV was detected by nested reverse transcription polymerase chain reaction (RT-PCR),and then directly genotyped by sequencing nested RT-PCR product of VP3/VP1 region.Ninty-nine blood samples from healthy children were collected as controls during the same period.Results Twenty-seven children (8.2%) were HPeV positive in 328 children.HPeV infections were found in all age groups of children and the highest frequency was seen in children <3 months old (18.2%,12/66).HPeV was detected in several months,with the peak in December (18.8%,9/48).Of all the positive samples,20 were genotyped successfully and identified to be HPeV1.No HPeV infections were found in blood of healthy controls.ConclusionsHPeV is the pathogen of CNS infections and sepsis in children.HPeV screening should be enrolled in the routine virus testing in specimens obtained from children.HPeV1 is the prevalent type in children in the year of 2009 in Shanghai.

Objective To detect the expression of long non-coding RNA (lncRNA) CCAT1 in human papillary thyroid cancer, and to observe the effect of CCAT1 down-regulation on the invasion and migration of human papillary thyroid cancer.Methods The expression of CCAT1 was detected in human normal thyroid Nthy-ori 3-1 cells and human papillary thyroid cancer TPC-1 cells.CCAT1 siRNA plasmid was transfected into TPC-1 cells.The effect of CCAT1 down-regulation on cell invasion and migration was observed by Transwell chamber assay and scratch test, and the expressions of BRAF, MUC15 and RKIP proteins were detected by Western blot.Results The level of CCAT1 in human papillary thyroid cancer TPC-1 cells was significantly higher than that in human normal thyroid Nthy-ori 3-1 cells.CCAT1 down-regulation significantly inhibited the invasion and migration of TPC-1 cells.The Transwell invasion assay revealed that the number of migrated TPC-1 cells in the CCAT1 down-regulation group was significantly lower than that in the control group.The scratch test showed an increased distance between cells in the CCAT1 down-regulation group compared to the control group, suggesting a reduced cell motility.The expressions of BRAF and MUC15 proteins were decreased in the CCAT1 down-regulation group, while that of RKIP protein was increased.Conclusions The expression of CCAT1 in papillary thyroid cancer cells is significantly higher than that in normal human thyroid cells.Down-regulation of CCAT1 in papillary thyroid cancer cells may inhibit the cell invasion and migration by regulating the expression of BRAF, MUC15 and RKIP proteins.

Objective To study the clinical characteristics of Behcet's disease (BD) complicated with leukemia and analyze the relationshp between the two diseases. Methods Five cases in the medical literature were retrieved and their data were analyzed. Results The clinical characteristics were : oral ulcersand fever (5 cases), skin lesions (3 cases), vulva ulcers (3 cases), eye lesions (3 cases), arthralgia (4 cases), diges-tive tract ulcerations and hemorrhage (1 cases). All cases coexisted with leukemia were shown to have various degrees of peripheral blood changes and history of immunosuppressive therapy. Among these, 3 cases were coexisted with acute granulocytic leukemia, 1 case with acute monocytic leukemia, 1 case with plasma cell leukemia respectively. All patients died within one year. Conclusion Close relationship can be observed between BD and leukemia from the point of view of the provocating factors, clinical features and drug use.

Objective To explore the changes in fractional anisotropy (FA) among cerebral infarction pa-tients using MR diffusion tensor imaging (DTI), and to verify the relationship between any FA changes and functional recovery. Methods Thirty-eight cerebral infarction patients were divided into two groups according to their recovery level using Brunnstrom's criteria. All the patients accepted routine MR and DTI examination, and FA values were measured during the acute, subacute and chronic stages of their recovery. Results Average FA values in the lesion area were significantly lower than in the corresponding contralateral area, and were highest daring the acute stage.There was no significant difference between the subacute and chronic stages. Conclusions The FA values of cere-bral infarction patients change during the different stages of recovery with a certain regularity. This may be valuable for clinical treatment and prognosis.

Objective To explore the sleep characteristics in first-episode schizophrenics and the effects of olanzapine on body weight and sleep-breathing disorder.Methods 36 first-episode schizophrenics (patient group) and 33 normal controls (control group) were tested with polysomnography(PSG),and compared the difference of PSG,sleep-breathing index and body mass index(BMI) before and after treatment in patient group.Results Before treatment,compared with control group,the patient group had significantly prolonged sleep latency((83.64± 10.62) min vs (29.41 ± 10.05) min),shortened total sleep time ((286.43 ± 17.04) min vs (343.66 ± 16.38)min),decreased sleep efficiency((65.73 ±11.47) vs (86.13 ± 8.15)),increased awake time and arousal number((65.70 ± 10.33) min vs (25.93 ± 9.60) min ; (38.26 ± 6.88) vs (14.40 ± 2.72)) in sleep continuity ; and increased N1 stage ((87.43 ± 11.35) min vs (36.55 ± 6.40) min),decreased N2,N3 stage ((100.53 ± 10.42)minvs (143.35±13.52)min;(49.83±7.51)minvs (87.52±9.74)min) in sleep structure (P < 0.05).After treatment,sleep continuity and sleep structure in patient group were improved,compared with control group,only BMI,arousal index and hypopnea index had statistic difference (P < 0.05).Conclusion The first-episode schizophrenics have both sleep continuity and sleep structure deficits.Although olanzapine treatment can improve sleep quality,long-term use of it may cause overweight and sleep-breathing disorder.
