Objective To explore the value of magnetic resonance perfusion imaging of 3D arterial spin labeling(3D-ASL)in the diagnosis of transient ischemic attack(TIA).Methods 78 of patients were diagnosed TIA on MR routine scan [T1 WI,T2 WI,T2-FLAIR,diffusion weighted imaging(DWI)],magnetic resonance angiography(MRA)and 3D arterial spin labeling(3D-ASL).The re-sult were analyzed by Chi-square test.Results In 78 patients,the abnormal routine scan was 0 case(0%);abnormal MRA 41 cases (52.6%);abnormal 3D-ASL 47 cases(60.2%);combination with each other were 60 cases(76.9%).29 cases with artery stenosis and abnormal ASL,12 case with artery stenosis and normal ASL,19 cases with normal vascular and abnormal ASL,18 cases with normal vascular and normal ASL.Conclusion 3D-ASL is better than routine magnetic resonance sequences in the diagnosis of TIA,which is convenient and should be a routine scanning sequence of TIA.3D-ASL,MRA and DWI have their own advantages and disadvantages, combination use can improve the diagnosis accuracy of TIA.

OBJECTIVETo observe the effect of traditional Chinese medicine storax on the concentration of combined western medicine sulpiride in brain and blood, discuss the effect of storax in inducing resuscitation and increasing the permeability of the gastrointestinal barrier (GB) and the blood-brain-barrier (BBB), and explore the interaction between storax and sulpiride.

METHODRats were orally administered with the drugs for one week, probes were implanted in their brains and necks by surgery. After balance for 60 min, brain microdialysis and blood microdialysis were adopted for collect dislysates from blood in right atrum and cerebral hippocampus at time periods of 30, 60, 90, 120, 150, 180 min. The concentration of sulpirde in the samples was detected by RP-HPLC. Statistical approaches were adopted to compare the contents of sulpirde in brain and blood of the two groups.

RESULTThe sulpiride combined with storax group showed a significant higher concentration of sulpiride than the pure sulpiride group. The pure sulpiride group showed a concentration ratio between sulpiride in brain and blood of 1:0.2; while the sulpiride combined with storax group increased the concentration ratio between sulpiride in brain and blood to 1:0.3. Compared with the pure sulpiride group, the sulpiride combined with storax group showed an increase of concentration by 39% in brain and 69% in blood.

CONCLUSIONStorax can notably increase the concentration of sulpiride in rat brain and blood, indicating that it can increase the permeation of sulpiride through gastrointestinal barrier and BBB. This study reveals the mechanism of storax in inducing resuscitation by promoting the permeation through gastrointestinal barrier and BBB.

After partial hepatectomy (PH) or liver injury, hepatocytes in a proliferating quiescent state are activated and begin to expand to repair the damaged liver. In recent years, studies have recognized that non-coding RNA (ncRNA) represented by microRNA (miRNA) and long non-coding RNA (lncRNA) can participate in liver regeneration by regulating the proliferation, apoptosis, autophagy, and proliferation and migration of hepatic progenitor cells (HPCs). This article reviews the relationship between miRNA, lncRNA, and liver regeneration, with a view to provide a new therapeutic strategies for liver disease and liver regeneration.

AIM: To investigate the radioprotective effect of adenine on irradiated lymphocytes and discover the possible mechanisms of protection. METHODS: Lymphocytes were pretreated for 12 h with adenine (0.001-0.1 μmol·L(-1)) and then exposed to 4 Gy radiation. Cell viability was observed by the MTS assay, apoptosis was detected by Annexin V-FITC/PI, DNA ladder, and caspase 3/7 activity. Caspase-9, Bax, and Bcl-2 gene expression was investigated by RT-PCR. RESULTS: Irradiation increased cell death and DNA fragmentation. Pretreatment with adenine significantly reversed this tendency. Furthermore, several anti-apoptotic characteristics of adenine were determined, including the ability to inhibit caspase 3/7, upregulate B-cell lymphoma (Bcl-2) and downregulate Bcl-2- associated X (Bax), capase-9 gene expression in 4 Gy-irradiated AHH-1 cells. CONCLUSION The results suggest that adenine had a radioprotective effect to inhibit apoptosis in a concentration dependent manner.

This study was aimed to investigate the quantity and subtypes of dendritic cells (DC) in patients with immune related pancytopenia (IRP) and to explore the role of DC in pathogenesis of IRP. The quantity of plasmacytoid dendritic cells (pDC, Lin(-)HLA-DR(+) CD123(+) cells) and myeloid dendritic cells (mDC, Lin(-)HLA-DR(+) CD11c(+)cells) in peripheral blood of 65 patients with IRP (37 new diagnosed and 28 remitted) and 17 healthy controls were analyzed by flow cytometry. The results indicated that the ratio of pDC in peripheral blood mononuclear cells (PBMNC) was (0.91 ± 064)% in new diagnosed group, which was significantly higher than that in remission group (0.39 ± 0.11)% and control group (0.29 ± 0.13)% (P < 0.01), while this ratio of pDC in remission group was higher than that in control group (P < 0.05). The ratio of mDC in PBMNC was (0.21 ± 0.20)% in new diagnosed group and (0.34 ± 0.21)% in remission group respectively, there was no statistical difference as compared with control group (0.29 ± 0.09)% (P > 0.05). The ratio of pDC to mDC in new diagnosed group was 6.75 ± 7.11, which was significantly higher than that in remission group (1.55 ± 0.93) and control group (1.07 ± 0.43, P < 0.01), there was no statistical difference between the ratio of remission group and control group (P > 0.05). The ratio of pDC in PBMNC of IRP group negatively correlated to ratio of Th1/Th2 (r = -0.347, P < 0.05), and positively correlated to the ratio of auto-antibody on membrane of BMMNC (r = 0.606, P < 0.05) and to the quantity of CD5(+)B cells (r = 0.709, P < 0.05), while it negatively correlated to the levels of hemoglobin (r = -0.381, P < 0.01) and platelets (r = -0.343, P < 0.01). The ratio of mDC in PBMNC positively correlated to the ratio of Th1/Th2 (r = 0.595, P < 0.05) and the level of hemoglobin (r = 0.292, P < 0.05). The ratio of pDC/mDC negatively correlated to ratio of Th1/Th2 (r = -0.395, P < 0.05), it positively correlated to the level of antibody on membrane of BMMNC (r = 0.421, P < 0.05) and the quantity of CD5(+)B cells (r = 0.423, P < 0.05), while it negatively correlated to the levels of hemoglobin (r = -0.304, P < 0.05) and platelets (r = -0.287, P < 0.05). It is concluded that the quantity of pDC in peripheral blood of IRP patients increases, which may be related to the immunopathogenesis of IRP.

Non-human primates (NHPs) are confirmed as reservoirs of Cryptosporidium spp., Giardia intestinalis, and Enterocytozoon bieneusi. In this study, 197 fresh fecal samples from 8 NHP species in Qinling Mountains, northwestern China, were collected and examined using multilocus sequence typing (MLST) method. The results showed that 35 (17.8%) samples were positive for tested parasites, including Cryptosporidium spp. (3.0%), G. intestinalis (2.0%), and E. bieneusi (12.7%). Cryptosporidium spp. were detected in 6 fecal samples of Macaca mulatta, and were identified as C. parvum (n=1) and C. andersoni (n=5). Subtyping analysis showed Cryptosporidium spp. belonged to the C. andersoni MLST subtype (A4, A4, A4, and A1) and C. parvum 60 kDa glycoprotein (gp60) subtype IId A15G2R1. G. intestinalis assemblage E was detected in 3 M. mulatta and 1 Saimiri sciureus. Intra-variations were observed at the triose phosphate isomerase (tpi), beta giardin (bg), and glutamate dehydrogenase (gdh) loci, with 3, 1, and 2 new subtypes found in respective locus. E. bieneusi was found in Cercopithecus neglectus (25.0%), Papio hamadrayas (16.7%), M. mulatta (16.3%), S. sciureus (10%), and Rhinopithecus roxellana (9.5%), with 5 ribosomal internal transcribed spacer (ITS) genotypes: 2 known genotypes (D and BEB6) and 3 novel genotypes (MH, XH, and BSH). These findings indicated the presence of zoonotic potential of Cryptosporidium spp. and E. bieneusi in NHPs in Qinling Mountains. This is the first report of C. andersoni in NHPs. The present study provided basic information for control of cryptosporidiosis, giardiasis, and microsporidiosis in human and animals in this area.
