Objective To investigate the effect of partial body-weight supported treadmill training ( PBW- STT) on function of lower limbs, walk function, ADL performance and quality of life of hemiplegic patient induced by cerebral infarction. Methods A total of 132 cerebral infarction patients were divided into a control group (n = 69) and a training group( n = 63) randomly. Both groups accepted routine rehabilitation therapy, and the training group accepted PBWSTT at the same time in addition. Both groups were evaluated with regard to their walking ability, func- tion of lower limbs, ADL performance and their quality of life by using Functional Ambulation Category (FAC) , Fugl-Meyer assessment (FMA) , Barthel index (BI) and SF-36 before and after rehabilitation treatment. Results The function of lower limb, walking ability, ADL performance and the quality of life of both groups were improved significantly after treatment, and those in the training group were improved to a significantly greater extent than those in the control group ( P

Objective:To investigate the feasibility of targeted imaging and therapy of prostate cancer using nanocomposite probes composed of fluorescent magnetic nanoparticles(FMCNPs) and single chain Fv(ScFv) antibody specific for gama-seminoprotein.Methods:The nanocomposite probes(FMCNPs-ScFv) were prepared by conjugating fluorescent magnetic nanoparticles with singlegama-chain Fv antibody specific gama-seminoprotein,and were characterized by high resolution transmission electron microscopy,fluorescent spectrum and magnetic spectrum.Nanocomposite probes were incubated with prostate cancer LNCaP cells,and the targeting results of nanocomposite probes were observed by fluorescent microscopy.The cytotoxicity effect of the nanocomposite probes was measured by MTT.Nude mice models of prostate cancer were established and identified by immunohistochemistry method.The nanocomposite probes were injected into nude mice via tail vein.The distribution of nanocomposite probes in the nude mice was observed by Micro-animal imaging system,targeted imaging of the prostate cancer was observed by MR instrument.The nude mice with prostate cancer were irradiated with 100 W magnetic field for 30 min,and the changes of tumor sizes were observed.Results:The FMCNPs-ScFv nanocomposite probes were successfully prepared.Nanocomposite probes entered into the cytoplasm of cancer cells and exhibited low cytotoxicity effect.Nude mice model with prostate cancer were successfully fabricated;the nanocomposite probes distributed quickly in the main organs of mice,and gradually concentrated on the tumor tissues within 24 h.MR images showed that the tumor images were gradually enhanced from 6 h to 24 h after injection of the nanocomposite probe.Four days after magnetic irradiation,the tumors in the nude mice grew slower compared with the control nude mice(P

OBJECTIVETo evaluate the relationship of vitamin D level with the development of necrotizing enterocolitis (NEC) in preterm infants.

METHODSA total of 429 preterm infants with a gestational age of <36 weeks, who were admitted to the department of neonatology within 2 hours after birth between January and December, 2016, were enrolled in the study. According to whether these infants developed NEC, the 429 subjects were divided into NEC group (n=22) and non-NEC group (n=407). Peripheral venous blood was collected from these preterm infants and their mothers at admission to measure the level of 25-hydroxyvitamin D (25-OHD). The two groups were compared in terms of the serum 25-OHD levels of preterm infants and their mothers. Pearson correlation analysis was used to investigate the correlation between the serum 25-OHD levels of preterm infants and their mothers. The distribution of vitamin D levels in preterm infants was compared between the two groups. The univariate logistic regression analysis was used to determine the risk factors for NEC in preterm infants.

RESULTSThe serum 25-OHD levels of preterm infants and their mothers in the NEC group were significantly lower than in the non-NEC group (P<0.001). In both groups, the serum 25-OHD levels of mothers and preterm infants were positively correlated with each other (P<0.001). The distribution of vitamin D levels (normal vitamin D level, low vitamin D level, vitamin D deficiency, and severe vitamin D deficiency) was significantly different between the NEC and non-NEC groups (P<0.001). The univariate logistic regression analysis showed that gestational age, birth weight, 25-OHD levels of preterm infants and their mothers, the duration of mechanical ventilation, the duration of oxygen inhalation, and the length of hospital stay were associated with the development of NEC (P<0.05).

CONCLUSIONSThe serum 25-OHD levels of preterm infants and their mothers may be related to the development of NEC in preterm infants, suggesting that vitamin D supplementation during pregnancy is important for preventing the development of NEC in preterm infants.
