BACKGROUND: Stem cell transplantation has a significant neuroprotective effect on neurological diseases. Current transplantation methods such as arteriovenous transplantation and brain stereotactic transplantation are not suitable for clinical application in preterm infants. OBJECTIVE: To explore the feasibility of nasal transplantation of human umbilical cord mesenchymal stem cells and human neural stem cells for the treatment of white matter injury in premature rat infants. METHODS: Human umbilical cord mesenchymal stem cells were prepared from human umbilical cord tissue, and human neural stem cells were prepared from human embryonic brain tissue. In vitro migration of two kinds of cells was assessed by Transwell method. Forty 3-day-old Sprague-Dawley rats were randomly divided into sham operation group, model control group, human umbilical cord mesenchymal stem cell transplantation group and human neural stem cell transplantation group, with 10 rats in each group. Rats in all groups except the sham operation group were treated with right common carotid artery ligation and hypoxia for 90 minutes to establish a rat model of white matter injury in the preterm infant. Totally 1×106 cells were delivered intranasally in the transplantation group at 3 days after injury. Each nostril was infused with 5×105, and each nostril was infused once. On day 7 after injury, MBP immunofluorescence staining was used to detect the expression of myelin basic protein in the white matter of the brain to identify the damage of the white matter injury model. At 24 hours after transplantation, human umbilical cord mesenchymal stem cell migration was detected by anti-HuNu immunohistochemical method and human neural stem cell migration was detected by CM-Dil fluorescent labeling method. RESULTS AND CONCLUSION: (1) On day 7 after modeling, compared with the normal side, the positive area of MBP decreased in cingulate band, corpus callosum and external capsule of the affected side in the model of brain white matter injury in preterm infants (P < 0.05), indicating a successful modeling. (2) In vitro experiments showed that the migration rate of human neural stem cells was the same as that of human umbilical cord mesenchymal stem cells. (3) At 24 hours after the nasal transplantation, human umbilical cord mesenchymal stem cells migrated to the cortex, corpus callosum and hippocampus on the normal side and the damaged side, and human neural stem cells migrated to the damaged cortex, corpus callosum and hippocampus, and human umbilical cord mesenchymal stem cells migrated more than human neural stem cells. (4) Overall, these findings indicate that 24 hours after the nasal transplantation, human umbilical cord mesenchymal stem cells could survive and migrate to the normal side and the injury side, and human neural stem cells could survive and migrate to the injury side; and the migration of human umbilical cord mesenchymal stem cells was more extensive than that of human neural stem cells.

Carthamus tinctorius L. is a traditional Chinese medicine with the effect of promoting blood circulation and removing blood stasis. HSYA (hydroxysafflor yellow A) is the main effective component of Carthamus tinctorius L. In order to study the inhibitory effects of HSYA against PMN (polymorphonuclear) activation induced by LPS (lipopolysaccharide), rabbit PMN adhesion potency which was activated by LPS through colorimetry method was observed. Cellular free calcium concentration was determined by fluorescence spectrophotometry. RT-PCR was applied to study the effect of HSYA on PMN TNF-alpha and IL-6 mRNA expression; The inhibition of HSYA on NF-kappaB activation was monitored with immunofluorescence. The results showed that after treated with HSYA, the increase of adhesion potency (HSYA dose 1.01 x 10(-4) mol x L(-1)), free calcium concentration (HSYA dose 3.1 x 10(-5) mol x L(-1)), TNF-alpha and IL-6 mRNA expression elevation (HSYA dose 5.2 x 10(-1) mol x L(-1)) induced by LPS were inhibited. HSYA can inhibit NF-kappaB p65 subgroup nuclear translocation (HSYA dose 5.2 x 10(-5) mol x L(-1)). It is suggested that HSYA is effective in PMN activation induced by LPS.

Objective To determine the level of ieptin (LEP) and soluable leptin receptor (sLEP-R) in the peripheral blood of rheumatoid arthritis (RA). The change of LEP/sLEP-R in patients with RA and the relationship between LEP/sLEP-R with osteoporosis is also investigated. Methods Sixty-four patients with RA and 60 normal controls were involved. Levels of LEP and sLEP-R were measured by ELISA. Bone mineral density (BMD) of non-dominant forearm, lumbar vertebrae(L_(1～4)) and hip were measured by dual energy X-ray absorptiometry. Results ① Compared with normal controls, the level of LEP in RA increased significantly,but the level of sLEP-R in RA decreased significantly (P<0.01). ② BMD of all detected regions in RA were significantly reduced than those in the normal controls (P<0.01). There was a higher incidence of osteoporosis in patients with RA (35.9%) than in normal controls (15.0%)(P<0.01). ③ There was a positive lineary correlation between age and the level of LEP in the peripheral blood of RA (P<0.01). There was negative lineary correlations between BMD and level of LEP in the peripheral blood of RA (P<0.05). There was a negative lineary correlation between age and level of sLEP-R in the peripheral blood of RA (P<0.01). There was positive lineary correlation between BMD and level of sLEP-R in the peripheral blood of RA (P<0.05). There was no correlations between clinical or laboratory parameters and level of LEP/sLEP-R in the peripheral blood of RA. ④ Analysis of Logistic Regression showed that the level of sLEP-R in the peripheral blood of RA was an independent protective factor for the occurrence of osteoporosis in RA (OR=3.089, P=0.017, 95%CI: 0.017-7.108). Conclusion The level of LEP in RA increases significantly, while the level of sLEP-R decreases significantly. There is a closely correlation between bone metabolism status and the level of LEP or sLEP-R in RA. The level of sLEP-R in the peripheral blood of RA is an independent protective factor for the occurrence of osteoporosis in RA.
