BACKGROUND:Stem cel s can be induced to differentiate into dopaminergic neurons in vivo and in vitro, which provides a theoretical basis for stem cel transplantation in the treatment of Parkinson’s disease
OBJECTIVE:To explore the feasibility and mechanism of intracerebral transplantation of umbilical cord blood mesenchymal stem cel s for treatment of Parkinson’s disease rats.
METHODS:Intracerebral injection of 6-hydroxydopamine was used to make Parkinson’s disease models in SD rats. Twenty-two model rats were randomized into cel transplantation group (n=12) and control group (n=10) and respectively injected intracerebral y with umbilical cord blood mesenchymal stem cel suspension and PBS. At 1-8 weeks after cel transplantation, intra-abdominal injection of apomorphine was performed every week to observe the rotation behaviors of rats;at the 2nd and 8th weeks, rat’s striatum and substantia nigra were taken for immunohistochemistry staining.
RESULTS AND CONCLUSION:The rotation behaviors were gradual y decreased with time in the cel transplantation, but had no changes in the control group. At 3-8 weeks after transplantation, there were significant differences in the rotation behaviors between the two groups (P<0.05). At 2 weeks after transplantation, tyrosine hydroxylase-positive cel s were found within and around the striatum of the cel transplantation group;but there were no exogenous cel s in the control group. At 8 weeks after transplantation, there were stil active cel s and tyrosine hydroxylase-positive cel s in the striatum of cel transplantation group, and there was no tyrosine hydroxylase expression in the striatum of the control group. These findings suggest that transplanted umbilical cord blood mesenchymal stem cel s can survive in the brain that are positive for tyrosine hydroxylase, which can improve the behavior abnormalities of Parkinson’s disease rats.

Objective An analysis was carried out for the reports of traditional Chinese medical syndrome patterns of psoriatic arthritis (PsA) patients in related reports issued in the recent 35 years, thus to explore the characteristics of syndrome patterns of PsA patients and to supply evidence for the syndrome classification. Methods Electronic retrieval was performed in the reports of PsA syndrome analysis issued in the Chinese medical journals from the year of 1979 to 2013. Traditional Chinese medical syndrome information of PsA patients was extracted from the reports, and then was standardized and classified. SPSS 17.0 software was applied for the analysis of occurrence frequency of syndromes, syndrome elements, tongue and pulse states. Results A total of 84 reports were obtained, and 26 reports met the inclusion criteria. In the 26 included reports, 10 kinds of tongue texture, 15 kinds of tongue fur and 22 kinds of pulse states were present. After the standardization of the syndromes, a total of 39 syndrome patterns were obtained. After combination of the similar syndromes, 14 syndromes were included into the analysis. In the 14 included syndrome patterns, the leading 5 patterns were wind-damp heat arthralgia, wind-heat with blood dryness, excessive heat toxin, wind-cold damp arthralgia, and liver-kidney deficiency. Fourteen syndrome elements were extracted from the syndromes, and 9 were included into the analysis after combination of the similar syndrome elements. The top syndrome elements were heat, phlegm-dampness, wind, dryness, deficiency, and blood stasis. Conclusion The syndrome patterns of PsA patients are various, and the syndrome elements of cold, heat, phlegm-dampness, wind, dryness, and blood stasis play an important role in the pathogenesis of PsA.

Objective To evaluate the effect of dexmedetomidine on autophagy in the hippocampal neurons of rats with traumatic brain injury (TBI).Methods Adult male Sprague-Dawley rats,aged 12-16 weeks,weighing 340-370 g,were randomly divided into 3 groups (n=80 each) using a random number table:sham operation group (group S),traumatic brain injury group (group TBI) and dexmedetomidine group (group Dex).The rats were subjected to a diffuse cortical impact injury caused by a modified weight-drop device to induce TBI.Dexmedetomidine 15 μg/kg was injected intravenously immediately after TBI in Dex group.At 24 and 48 h after TBI,neurological deficit score (NDS) was assessed,Morris water maze test was performed,and brains were removed for detection of brain water content in the brain tissue.At 6,12,24 and 48 h after TBI,the expression of hippocampal LC3]Ⅱ was determined using Western blot analysis.Results Compared with group S,brain water content and NDS were significantly increased at 24 and 48 h after TBI,the escape latency was prolonged,and the expression of hippocampal LC3 Ⅱ was upregulated at 6,12,24 and 48 h after TBI in TBI group.Compared with TBI group,brain water content and NDS were significantly decreased at 24 and 48 h after TBI,the escape latency was shortened,and the expression of hippocampal LC3 Ⅱ was down-regulated at 6,12,24 and 48 h after TBI in Dex group.Conclusion The mechanism by which dexmedetomidine reduces TBI is related to inhibition of autophagy in the hippocampal neurons of rats.
