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.

Methods Resonant liposuction was employed in 136 cases, including local fat deposit in some part of the body. Operation's safety, mircotrauma, speediness, and effect after operation were observed. Results The follow-up for 6 to 24 months showed that the reconstructed body figure was very satisfactory. Conclusion Resonant liposuction is an ideal method to reconstruct the body figure owing to its safety, miniinvasion, easy performance and efficacy.

Objective To evaluate the efficiency of different wash methods for removing organophosphorus pesticide residues from cucumber. Methods The cucumber samples were soaked with tap water, washed rice water, salt solution and detergent solution respectively for 2 to 15 minutes then organophosphorus pesticide residues in the soak water samples were determined with ultrasonic extraction and gas chromatography. Results Soaked in tap water for 2 to 5 minutes was the most effective and convenient way to remove methamidophos and dimethoate with the highest removing rate (about 70%). Conclusion Soaked with tap water for 2 to 5 minutes is more efficient for removing organophosphorus pesticide residues from vegetable.

With the understanding of autoimmune encephalitis many novel types of autoimmune encephalitis and related antibodies have been identified. There are some cases of autoimmune encephalitis with autoantibody overlapping syndromes or phenotype overlapping syndromes, which bring challenges to diagnosis and treatment in practice. The relevant literature was reviewed and the clinical characteristics, pathological mechanism and treatment of overlapping syndromes associated with autoimmune encephalitis were summarized, in order to provide a reference for the management of autoimmune encephalitis with overlapping syndromes.

OBJECTIVE To study the frequencyof extracapsular spread (ECS) in neck metastasis and its impact on prognosis in supraglottic carcinoma. METHODS A total of 177 patients with radical or modified neck dissection between Jan. 1994 and Dec. 1997 for supraglottic carcinoma were summarized. Transparent lymph node detection and a series of sectioning method were applied on all neck dissection specimens. The SPSS software package (version 11.5) was used to make statistical analysis. Survival curves were calculated with the Kaplan-Meier model. Impact of extracapsular spread on prognosis was assessed for significance with the Log-Rank test. RESULTS Eighty one patients were pathologically positive in neck specimens and the neck metastatic rate was 45.8 %. ECS was found in 32 cases and the ECS frequency was 39.5 % (32/81). The ECS was related with pathological N stage and the number of positive nodes. Patients with ECS had a higher possibility of regional recurrence and contralateral metastasis. The 5-year survival rates of patients with neck metastasis ECS- and patients with ECS+ were 61.9 % and 22.2 % respectively. The differences had statistically significance. CONCLUSION ECS in neck metastasis affects the prognosis in patients with supraglottic carcinoma. If bilateral neck dissection was not selected simultaneously, close follow-up on contralateral neck should be selected in patients with ECS because of a higher incidence of contralateral neck metastasis.

Objective To studied the effects of administering a second rinse solution of low-potassium-dextran(LPD) before reperfusion on the donor lung of rat after long time,cold ischemic preservation.Methods Twenty-four rats were randomly divided into control group(n=12) and trial group(n=12).Donor lungs of control group were flushed with LPD solution.The levels of malonaldehyde(MDA),myeloperoxidase(MPO) and interleukin-8(IL-8) were tested in the tissue of right lung and the left lungs were reperfused with venous blood for 30 minutes.The partial pressure of oxygen(PaO_2),PaP and PawP were measured at every 10 minutes intervals during reperfusion.After reperfusion,the MDA,MPO activity and interlukin-8(IL-8) were determined in the lung tissue.Results The levels of MDA,MPO and IL-8 decreased significantly in right lung of trial group than those in control group(P

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.
