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 investigate the current status of self-efficacy and care ability among stroke patients′ family caregivers and explore the correlation between them. Method A total of 79 stroke patients and family caregivers were engaged in the investigation by demographical data questionnaires, general self-efficacy scale and questionnaire for assessing the comprehensive care-giving ability of stroke caregivers. Results The score on self-efficacy of the family caregiver was (27.16 ± 5.64) and the total score on care ability was (90.01 ± 16.57). There was a positive correlation between self-efficacy and care ability of family caregivers(P<0.05). Conclusions The self-efficacy and care ability of stroke patient′s family caregivers are at middle level. Their self-efficacy is positively correlated with their care ability. The nurses can improve the ability of daily caring of family caregivers by enhancing their self-efficacy.

Objective To investigate the outcomes of patients undergoing off-pump coronary artery bypass grafting (OPCABG) under morphine-fentanyl combined anesthesia. MethodsSeventy-two patients aged 41-64 yr undergoing OPCABG were randomly divided into 2 groups (n = 36 each): Ⅰ group morphine + fentanyl (group MF) and Ⅱ group fentanyl (group F). Anesthesia was induced with midazolam, etomidate, and vecuronium.Fentanyl 10-20 μg/kg was given iv when needed. The patients were mechanically ventilated after tracheal intubation. Anesthesia was maintsined with inhalation of 0.5%-2.0% isoflurane and intermittent iv boluses of vecuronium in both groups. Morphine 0.15 mg·kg-1·h-1 + fentanyl 8 μg·kg-1·h-1 were infused during operation in group MF, while in group F fentanyl 10 μg·kg-1·h-1 was infused. Morphine 0.75 mg/h was infused in group MF or fentanyl 10 μg/h in group F for postoperative analgesia after extubation. Recovery from anesthesia was assessed using a nine point (QoR) questionnaire. Pain was measured with VAS score and sedation with Ramsay sedation score ( 1 = fully awake, 6 = asleep, no response to verbal stimulus). The postoperative complications were recorded. ResultsQoR scores were significantly higher in group MF and in group F. The incidence of postoperative febrile reaction was significantly reduced in group MF. There was no significant difference in Ramsay sedation score and other postoperative complications between the 2 groups. ConclusionMorphine-fentanyl combined anesthesia is more beneficial for the prognosis in patients undergoing OPCABG compared with fentanyl combined anesthesia.

Aim To investigate the myocardial hypertrophy,the expression of transforming growth factor ?1(TGF-?1),Smad3 and Smad7 proteins in spontaneous hypertensive rats(SHR)and the effects of benazepril and candesartan.Methods SHRs of 12 weeks old were given benazepril and candesartan for 12 weeks.The tail arterial pressure was measured every two weeks.At 12 th weekend,cardiac configuration,heart mass index,area of cadiocytes,concertrations of AngⅡin plasma and myocardium,expressions of TGF-?1、Smad3 and Smad7 proteins were measured respectively.Results The arterial pressure,wall thickness,heart mass index,area of cardiocytes and the expressions of TGF-?1,Smad3 proteins increased in SHRs but were attenuated after the treatment of benazepril or candesartan.After the combined treatment,the synergistic effect could be observed.The levels of cardiac tissue and plasma AngⅡwere reduced.The expressions of Smad 7 were up-regulated after the treatment of benazepril or candesartan,while they were stable after the combined use.Conclusion There is a synergistic effect of attenuating myocardial hypertrophy in SHRs by combined use of benazepril and candesartan.It may be related to the regulation of Ang Ⅱ,decreasing the expressions of TGF-?1 and Smad3.

Objective To investigate the effects of different thickness of cell culture dishes on fluorescent image with confocal microscope.Methods The fluorescent staining experiments of live cells and fixed cells were used to determine the differences among three dishes with different thickness coverslips of 0.085～0.13 mm,0.13～0.16 mm and 0.16～0.19 mm,while the cell appearance,fluorescence lightness and mean of fluorescence intensity were studied with confocal microscope.Results Demonstrated by the results of cytoskeleton staining experiments,the dish with 0.13～0.16 mm thickness coverslip was the best choice for confocal microscope,the dish with 0.16～0.19 mm thickness coverslip was the second one,the dish with 0.16～0.19 mmthickness coverslip was the last one.ConclusionThe dish with 0.13～0.16 mm thickness coverslip is the best choice for confocal microscope.On this type of dish,the cytoskeleton is unfolding and clear after staining.The intensity of fluorescence is the strongest,and the imaging effect is the best.

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 determine the roles of thymic stromal lymphopoietin receptor (TSLPR) and its antibody in airway inflammatory response in asthmatic mice, and to promote maturation and activation of dendritic cells (DCs) in mouse airway. Methods BALB/c mice were randomly divided into group A, B and C. The mice in group B and C were intraperitoneally injected with OVA for allergization while the mice in group A were intraperitoneally injected with PBS as the normal control. The mice in group B and C were treated by inhalation of non-specific IgG and TSLPR IgG respectively, before provocation of asthma using OVA. The bronchoalveolar lavage fluid (BALF) of the mice in different groups were collected for cell differential counts and quantitative detection of IL-4, IL-5, IFN-γand IL-10 levels by ELISA. Moreover, the pulmonary tissue specimens of the mice were collected for pathological examination, and the numbers and phenotypes of DCs from the local lymph nodes and pulmonary tissue were determined by flow cytometry. Results The levels of all the tested cytokines in the BALF from mice in group B and C were remarkably higher compared to those from mice in group A (P<0.01). However, both the IL-4 and IL-5 levels in the BALF from group C mice that pre-blocked with TSLPR IgG were lower than those from group B (P<0.05, P<0.01), whereas both the IFN-γ and IL-10 levels in the BALF from group C mice were higher than those from group B (P<0.05, P<0.01). Furthermore, the numbers of total cells, eosinophils and lymphocytes in the BALF from group C mice were also lower than those from group B (P<0.01). A large number of inflammatory cell infiltration around the bronchus, beaker cell proliferation and mucous secretion reinforcement could be found in the samples from group B mice, while slight inflammatory cell infiltration and beaker cell proliferation in the samples from group C mice. The numbers of DCs in mediastinal lymph node and the levels of I-Ad, CD40, CD80 and CD86 expression of pulmonary DCs from group B mice were higher than those from group C mice (P<0.05). Conclusion TSLP/TSLPR have an effect on promoting asthma, which is closely relative to its regulation of DCs activation. And the interference of TSLPR antibody can decrease the effect of TSLP/TSLPR which indicating a potential of the antibody as a novel anti-asthma drug.

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 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.
