Objective:To detect serum levels of vitamin A (Vit A), vitamin D(Vit D)25-hydroxy vitamin D[25-(OH)D] and vitamin E(Vit E) in children aged 0-6 years in Tibetan Plateau of Garzi Prefecture, thus providing references for physical examinations and prevention of 4 key diseases (rickets, malnutrition anemia, pneumonia and diarrhea) in children in plateau areas by relevant government departments.Methods:A total of 2 122 children who participated in physical examination in 12 townships of Xiangcheng County and 14 townships of Daocheng County, Garzi Tibetan Autonomous Prefecture, Sichuan Province from April 2017 to April 2019 with 0-6 years old were recruited for surveying physical measurements and collection of venous blood.Serum Vit A and Vit E levels were detected by high performance liquid chromatography.Serum levels of 25-(OH)D were detected by high performance liquid chromatography tandem mass spectrometry.The relationship between Vit A, Vit E and 25-(OH)D levels with the gender, age, seasonal change and altitude was analyzed.Results:The serum Vit A level, subclinical Vit A deficiency rate and marginal vitamin A deficiency rate were(1.05±0.27) μmol/L, 8.15%(173/2 122 cases) and 45.99%(976/2 122 cases), respectively in 2 122 children with 0-6 years old.There were significant differences in the serum Vit A level, the subclinical Vit A deficiency rate and the marginal vitamin A deficiency rate in children with different ages, seasons and altitudes (all P<0.05). The serum level of 25-(OH)D and 25-(OH)D deficiency rate insufficient rate were (24.65±6.45) ng/L, 6.03%(128/2 122 cases) and 16.59%(352/2 122 cases), respectively.There were significant differences in the serum level of 25-(OH)D, 25-(OH)D deficiency rate and 25-(OH)D insufficient rate in children with different ages and seasons (all P<0.05). The mean serum Vit E level, Vit E deficiency rate and Vit E insufficient rate were (7.81±1.74) mg/L, 2.78%(59/2 122 cases) and 29.59%(628/2 122 cases), respectively.There were significant differences in serum Vit E level, Vit E deficiency rate and Vit E insufficient rate in children with different ages and seasons (all P<0.05). The mean serum levels of Vit A and Vit D remained the lowest before the age of 1 year, and their deficiencies at this age were the most significant.The mean serum level of Vit E remained the lowest in >1-2 years old, and its deficiency and insufficient at this age were the most significant.Vit A, D and E levels were significantly affected by seasonal changes, which were significantly higher in the summer than in the spring, autumn and winter.In addition, Vit A and 25-(OH)D were significantly affected by the altitude, which were the lowest above 4 km altitude. Conclusions:The overall serum levels of Vit A, 25-(OH) D and E in children with 0-6 years old in Tibetan Plateau areas of Ganzi Prefecture are lower than those in plain areas.Vit A, 25-(OH) D and Vit E levels significantly differed in the age, season and altitude, which are related to the lack of local resources, insufficient maternal nutrition during pregnancy and insufficient intake after birth, as well as temperature and light caused by changes in local seasons and altitude.Therefore, it is necessary to make reasonable supplements during pregnancy to prevent vitamin deficiency.

Objective To explore the relationships between inappropriate parenting styles,emotional regulation strategies and self-injury.Methods A total of 1 096 medical students anonymously completed adolescents self-harm scale,emotion regulation scale (ERS) and the rejection and over-protection subscales of parental bonding instrument (PBI).Results The scores of paternal rejection,maternal rejection,paternal over-protection,maternal over-protection,cognitive reappraisal,expression suppression and self-injury were (4.3±3.3),(3.9±3.0),(5.7±3.3),(6.1±3.5),(36.1±6.7),(25.7±7.4) and (1.0±2.9),respectively.The scores of self-injury were positively correlated with the scores of paternal rejection,maternal rejection,paternal over-protection,maternal over-protection and expression suppression (r =0.08-0.20,P＜ 0.01),meanwhile negatively correlated with the scores of cognitive reappraisal(r=-0.10,P＜0.01).Cognitive reappraisal mediated the relationship between parental rejection and self-injury,which accounted for 9.3％.Expression suppression mediated the relationship between parental rejection,parental over-protection and self-injury,which accounted for 14.5％ and 17.9％,respectively.Conclusion The emotion regulation strategy act as a mediator between the inappropriate parental styles and self-injury in medical students.In addition,different emotion regulation strategies (cognitive reappraisal and expression suppression) play different roles in such relationship.

Objective:The tumorigenesis, progression, and metastasis of lung cancer are mostly governed by the immunosuppres-sive profile. This study aimed to explore the levels of various immunosuppressive inhibitory molecules in lung-cancer patients subject-ed to different chemotherapy cycles. Methods:Thirty-three patients with advanced lung cancer (ALC;stages III-IV) without receiving prior chemotherapy and 23 healthy subjects were enrolled in our study. Peripheral blood samples were collected from the patients be-fore each chemotherapy cycle. The inhibitory markers expressed in T cells such as TIM3, PD-1, and CTLA4 were analyzed by flow cy-tometry. Results:The percentages of CD4+TIM3+, CD8+TIM3+, CD4+PD-1+, CD8+PD-1+, CD4+CTLA-4+, and CD8+CTLA-4+T cells in the peripheral blood of the ALC patients were significantly higher compared to the controls. The percentage of CD4+TIM3+, CD8+TIM3+, CD4+PD-1+, and CD8+PD-1+T lymphocytes in the peripheral blood of patients (n=19) who achieved PR or SD significantly de-creased after five cycles of chemotherapy (P<0.05). Similarly, the percentages of CD4+CTLA-4+and CD8+CTLA-4+T cells in the pa-tients also decreased after five cycles of treatment. Conclusion:The immune status of ALC patients was evidently suppressed. Effec-tive chemotherapy successfully potentiated effective immune responses by downregulating inhibitory molecules in T cells.

OBJECTIVETo investigate the reliability of magnetic-activated cell sorting (MACS) combined with multiplex ligation-dependent probe amplification (MLPA) in the detection of the molecular cytogenetic abnormalities in multiple myeloma.

METHODSThe bone marrow cells were collected from 29 patients with multiple myeloma. The immuno magnetically sorted and unsorted cells were detected for TP53 and RB1 expressions using MLPA probes and the results were compared with fluorescent in situ hybridization (FISH).

RESULTSThe detection success rate was 100% for MLPA, which yielded results with an concordance rate of 99.1% with the FISH results. The positivity rates of MLPA and FISH were both increased after immunomagnetic sorting of the bone marrow cells.

CONCLUSIONMLPA can well suit the clinical needs for detecting molecular cytogenetic abnormalities in multiple myeloma, and the samples should be immuno magnetically sorted before the assay.

BACKGROUND: Present therapeutic tool cannot supplement infarct myocardium. Studies have shown that stem cell transplantation can promote regeneration of myocardium and vessels and improve heart function and prognosis.OBJECTIVE: To observe changes in morphology and hemodynamics in myocardium following embryonic stem cell transplantation in and surrounding the acute myocardial infarct site.DESIGN, TIME AND SETTING: The randomized, controlled, animal study was performed at the Laboratory of Neurobiology,Department of Human Anatomy and Neurobiology, Xiangya Medical College, Central South University from March 2007 to October 2008.MATERIALS: A total of 40 SPF grade Wistar rats were equally randomized into 4 groups, normal control, infarct model,central transplantation and peripheral transplantation groups. Embryonic stem cells-D3 (ES-D3) and Buffalo rat hepatocytas were supplied by Shanghai Cell Institute, Chinese Academy of Sciences.METHODS: Following resuscitation, ES-D3 cells at (2.0-5.0)×107/L were incubated in a flask, and induced to in vitro differentiate in conditioned medium containing Buffalo rat hepatocytes. Except normal control group, rat models of acute myocardial infarction were established by ligating left anterior descending coronary artery in the infarct model, central transplantation and peripheral transplantation groups. At 1 week following model induction, ES-D3 cells were labeled by BrdU for 1 day, and implanted at 1×109/L. Three sites were selected in the infarct site in the central transplantation group. 10 μ L cell suspension (104 cells) was implanted in the ventricular wall through each site. In the peripheral transplantation group, an equal volume of cell suspension was separately implanted in three peripheral infarct sites by the same method.MAIN OUTCOME MEASURES: Results of immunohistochemistry and hemodynamics were measured.RESULTS: ES-D3 cells in buffalo rat hepatocyte conditioned medium presented regular colony-shaped. At 8 days following differentiation, some embryo proper had spontaneous rhythmic contraction, showed positive reaction of cardiac troponin T after immunostaining. Under the electron microscope, myotube and muscle fiber appeared, which verified the differentiation of cardiomyocytes. Cells were positive for BrdU in the peripheral transplantation group, but negative in the central transplantation group. Cells were also positive for cardiac troponin T. 4 weeks following transplantation, left ventricular systolic pressure,minimum/maximum rate of ventricular pressure (±dp/dtmax) were significantly reduced (P ＜ 0.01), but left ventricular end diastolic pressure was significantly increased (P ＜ 0.01), left ventricular mass and left ventricular mass index were significantly increased (P ＜ 0.01 ) in the infarct model group compared with the normal control group. Compared with the infarct model group, no significant changes in hemodynamics indices were found in the central transplantation group (P ＞ 0.05); left ventricular systolic pressure, ±dp/dtmax were significantly increased (P ＜ 0.01), left ventricular end diastolic pressure was significantly decreased (P ＜ 0.01 ), left ventricular mass, left ventricular mass index and infarct area were significantly reduced(P ＜ 0.01) in the peripheral transplantation group.
