To improve the CT diagnosis of cerebral angioreticuloma, 3 cases of pathologically proven cerebral angioreticuloma were reviewed. The results showed that the image of CT of the first case revealed an irregular, parenchymatous mass located in the right temporallobe and middle cranial fossa.In the second patient,the image showed a annular mass with cystic consistency,surrounded by an area of edema, situated in the right frontal lobe,while in the third patient there was an irregular high density mass with an area of edema lying in the left frontal lobe and along the middle line. Pathological diagnosis of the first patient was mixed angioreticuloma and glioblastoma, and that of the others were angioreticulomas. the results suggested that if the mass in the cerebrum was obviously enhanced in CT, the diagnosis of angioreticuloma should be considered.

In October 2003, a new bacterial disease with symptoms similar to those caused by Xanthomonas axonopodis pv. poinsettiicola was observed on poinsettia leaves at a flower nursery in Zhejiang Province of China. Three Xanthomonas strains were isolated from infected plants and classified as X. axonopodis. They were differentiated from the pathotype strain LMG849 of X. axonopodis pv. poinsettiicola causing bacterial leaf spot of poinsettia by comparison of pathogenicity, substrate utilization and BOX-PCR genomic fingerprints.

OBJECTIVETo compare the efficacy difference of analgesia and detumescence on ankle sprain among acupuncture at Xiaojie point combined with tendon regulation manipulation, acupuncture at Xiaojie point and tendon regulation manipulation.

METHODSSixty cases of ankle sprain were randomized into a combined therapy group, a Xiaojie point group and a tendon-regulation manipulation group, 20 cases in each one. The combined therapy of acupuncture at Xiaojie point and tendon regulation manipulation, the acupuncture at Xiaojie point and the simple application of tendon-regulation manipulation were applied respectively in the three groups, once a day, 3 treatments were required. The symptom score such as pain, ecchymosis, swelling and motor dysfunction and the total score were observed before and after treatment in the three groups. The different values of pain and swelling scores were compared before and after treatment in the three groups. The efficacy was compared among the groups.

RESULTSThe total effective rate was 100.0% (20/20) in each group. But the curative rate was 85.0% (17/20) in the combined group, 65.0% (13/20) in the Xiaojie point tion manipulation group. After treatment, the symptom scores of pain, ecchymosis, swelling and motor dysfunction and the total score were all improved as compared with those before treatment in the three groups (P < 0.01, P < 0.05). The pain score in either the combined therapy group or Xiaojie point group was lower than that in the tendon-regulation manipulation group after treatment (0.20 -/+ 0.41, 0.15 +/- 0.37 vs 0.60 +/- 0.50, both P < 0.05). Swelling score in the Xiaojie point group was different significantly from that in the tendon-regulation manipulation 0.49 vs 06.4 vs. 20+0.41, P < 0.05). The different value of pain score in either the combined therapy group or Xiaojie point group was higher than that in the tendon-regulation manipulation group before group after treatment (0.65 bined therapy group or Xiaojie point group was higher than that in the tendon-regulation manipulation group before and after treatment (2.35 +/- 0.59, 2.45 +/- 0.51 vs 2.00 +/- 0.46, both P < 0.05). The different value of swelling score in the tendon-regulation manipulation group was higher than that in the Xiaojie point group before and after treatment (2.30 +/- 0.57 vs 1.60 +/- 0.60, P < 0.05).

CONCLUSIONAcupuncture at Xiaojie point combined with tendon-regulation manipulation achieve an apparent effect of analgesia and detumescence on ankle sprain.

Objective To study the change and significance of osteoprotegerin(OPG)/receptor activator of NF κB ligand(RANKL)during the process of rat arterial smooth muscle cells (SMC) to differentiate subgroups:7 d (early) subgroup and 14 d (late) subgroup.into osteoblast-like cells.Methods The rat arterial SMCs were divided randomly into the SMC group,atorvastatin group,and osteoblast-like group.Each group was also divided into 2.The osteoblast-like group was given β-glycerophosphate and vitamin C in culture medium,the atorvastatin group was given both β-glycerophosphate,vitamin C and atorvastatin.Von Kossa staining,Ca2+ content assay,ALP activity assay and osteocalcin assayed with Western blot were used to check the level of calcification.Real-time PCR was used to check the mRNA expressions of OPG and RANKL.Results There was high expression of OPG (early 2.71 ±0.08,late 2.69 ±0.02) but no RANKL in the SMC group all the time.The expressions of OPG were increased in the early subgroup and decreased in late subgroup in the atorvastatin group (early 3.52±0.05,late 2.50±0.03) and osteoblast-like group (early 4.18±0.10,late 2.30 ± 0.11).And the expressions of RANKL were both increased in the atorvastatin group and osteoblast-like group dnring the calcification process (from 1.01 ± 0.19 to 2.40 ± 0.10,and from 1.70±0.07 to 3.22±0.11,respectively).Among the three groups,the ratio of OPG/RANKL was decreased with the increasing calcification level (F =52.93,2.33,both P＜0.05).And compared with the early subgroups,the ratio of OPG/RANKL in the late subgroups was also decreased along with the increase of calcification level in each group(F=38.71,1.74,both P＜0.05).Conclusions The ratio of OPG/RANKL has a negative correlation with the level of the osteoblast-like cells differentiation,and atorvastatin could inhibit the calcification.

OBJECTIVETo explore the molecule mechanism of Salidroside inducing directional differentiation of mouse mesenchymal stem cells (MSCs) into neuronal cells.

METHODSThe mouse multipotent mesenchymal precursor cell line (D1) was taken as the objective. Cultured MSCs were divided into the negative control group (complete culture solution), the positive control group (containing 1 mmol/L β-mercaptoethanol), the Salidroside induced group (20 mg/L Salidroside), and the blocked group (20 ng/ ml DKK1, a special inhibitor of Wnt/β-catenin signal pathway). All cells were inoculated in a 6-well plate (1 x 10(4) cells/cm2) and grouped for 24 h. The expression of p-catenin was detected by fluorescence Immunochemistry in the negative control group, the positive control group, and the Salidroside induced group. The expression of neuron-specific enolase (NSE), beta 3 class III tubulin (β-tubulin III), nuclear receptor related factor 1 (Nurr1), glial fibrillary acidic protein (GFAP) mRNA, Wnt3a, β-catenin, low-density lipoprotein receptor-related protein6 (LRP6), Axin mRNA were detected using reverse transcrip- tion PCR (RT-PCR). The expression of β-catenin and NSE protein were analyzed by Western blot in the negative control group, the positive control group, and the Salidroside induced group. Ca2+ chelating agents (EGTA), L-type Ca2+ channel blocker (Nifedpine), and IP3Ks special inhibitor (LY294002) were used to block Ca2+ signal pathway respectively. The expression of Wnt3a, LRP-6, Axin, glycogen syn- thase kinase (GSK-3), and β-catenin mRNA were detected by RT-PCR. The β-catenin protein expression was analyzed using Western blot.

RESULTSCompared with the positive control group, β-catenin protein was strong positively expressed; the expression of Wnt3a, β-catenin, LRP6, Axin, NSE, β-tubulin III, Nurr1 mRNA, and NSE protein were obviously up-regulated in the Salidroside induced group (P < 0.01). Compared with the positive control group and the Salidroside induced group, β-catenin, NSE, Nurr1, and β-tubulin III mRNA expression decreased; β-catenin and NSE protein expression were also down-regulated in the blocked group (P < 0.01). Compared with the Salidroside induced group, the expression of Wnt3a, LRP-6, β-catenin, and Axin mRNA were down-regulated in the Ca2+ signal blocked group and the salidroside induced group (P < 0.01, P < 0.05).

CONCLUSIONSalidroside affected directional differentia- tion of MSCs into neuronal cells through Wnt/β-catenin and Ca2+ signal pathway.

Objective To investigate the risk factors of recurrent ischemic stroke, and evaluate the severity and short-term outcome. Methods From March, 2014 to March, 2015, 238 patients with recurrent ischemic stroke and 378 patients with initial ischemic stroke matched with gender and age were enrolled. The clinical data of two groups were compared and the non-conditional Logistic regression model was made to analysis the risk factors of recurrent ischemic stroke. The National Institute of Health Stroke Scale (NIHSS) score as ad-mission and discharge, and the neural function improvement rate of two groups were compared. Results The incidences of leukoarailsis (χ2=8.666), hypertension (χ2=8.189), smoking (χ2=6.973) and alcohol consumption (χ2=4.722) were higher in the recurrent group than in the pri-mary group (P<0.05). Logistic regression analysis showed that leukoarailsis (OR=1.690, 95%CI:1.198~2.384, P=0.003), hypertension (OR=1.715, 95%CI:1.135~2.592, P=0.010) and smoking (OR=1.896, 95%CI:1.233~2.915, P=0.004) were the independent risk factors of recur-rent ischemic stroke. The NIHSS scores as admission and discharge were significantly higher (t=-3.645, t=-4.675, P<0.001), and the neural function improvement rate was lower (t=2.643, P<0.01) in the recurrent group than in the primary group. Conclusion Hypertension, leuko-arailsis and smoking are independent risk factors for recurrent ischemic stroke. Recurrent ischemic stroke is more serious than initial isch-emic stroke, and the short-term neural function recovers more slowly.
