In the present study ~3H-Leucine or WGA-HRP was injected into the superior colliculus of one side in the rat.The terminal areas of the efferent projection fibers from the superior colliculus were examined. The efferent fibers of the superfical layer of the superior colliculus descended ipsilaterally to terminate in the parabigeminal nucleus(predominantly the dorsal and ventral part of the same side)and dorso-lateral part of the ipsilateral pontine nucleus.Ascending projections terminated to the medial geniculate nucleus,the posterior pretectal nucleus and latero-posterior nucleus of the thalamus(all bila- terally,but with ipsilateral predominance),the ipsilateral medial and lateral optic nuclei,and the dorsal and ventral lateral geniculate nucleus.In addition,labeled granules were also found in bilateral optic tracts and the optic chiasma. The efferent fibers of the middle and deep layers terminated to the ipsilateral central gray,the nucleus of Darkschewitsch,the interstitial nucleus of Cajal,the cuneiform nucleus and the contralateral superior colliculus.Ascending fibers ter- minated to the medial geniculate nucleus,the suprageniculate nucleus,the anterior- pretectal nucleus,the postero-lateral nucleus of the thalamus(all bilaterally,but more on the ipsilateral side),the parafascicular nucleus,the zona incerta,the ventral nucleus of the thalamus(all ipsilaterally).Descending fibers terminated to ipsilateral parabigeminal area and the parabigeminal nucleus,the dorso-lateral part of the pontine nucleus,the lateral part of the inferior colliculus,the reticular formation of the medulla oblongata and pons,and the lateral part of the inferior olive.The fibers terminated also to contralateral nuclei such as the parabigeminal nucleus,the medial part of the reticular formation of the medulla oblongata and ports,the medial accessory nucleus of the inferior olive,the anterior horn of the cervical spinal cord.

BACKGROUND: Total glucosides of paeony, effective component extracted from peony, has good inflammatory and analgesic effect. OBJECTIVE: To investigate the curative effect and side effect of total glucosides of paeony combined with methotrexate and sulfasalazine in the treatment of ankylosing spondylitis. DESIGN: Randomized and controlled observation SETTING: Department of Rheumatology , Guangdong Hospital of Traditional Chinese Medicine PARTICIPANTS: Totally 80 inpatients with ankylosing spondylitis hospitalized in the Clinic of Department of Rheumatology, Guangdong Hospital of Traditional Chinese Medicine from June 2003 to April 2004 were involved. The patients were randomly divided into 2 groups with 40 patients in each group. Informed consent was obtained. METHODS: Experimental group: 2 capsules of total glucosides of peony was taken orally, three times per day; methotrexate 10 mg/time, once per week; sulfasalazine 0.5 g/time, three times per day. Control group:methotrexate and sulfasalazine were taken orally and the dosage and method were the same as those in the experimental group. Two groups all used the same NSAID (Nimesulide) , 0.1 g/time, twice per day. The period of the treatment was 3 months. Evaluation of spinal column function and laboratory examination was performed before treatment and 4, 8 and 12 weeks after treatment. MAIN OUTCOME MEASURES: Primary outcomes: Bath ankylosing spondylitis activity index, Bath ankylosing spondylitis function index [1-2],duration of morning stiffness, systemic pain and spinal pain on a four point Likert scale, overall assessment of patient and physician on a four point scale. Secondary outcomes: ①erythrocyte sedimentation, C-reaction protein,Schober test, chest expansion, Occiput to wall distance and finger to floor distance.② Adverse events and side effects. RESULTS: The observation of 38 patients in the experiemtnal group and 37 patients in the control group was completed. ①Result of Bath ankylosing spondylitis activity index, Bath ankylosing spondylitis function index,duration of morning stiffness, pain and spinal pain on a four point Likert scale, overall assessment of patient and physician on a four point scale:The indices at week 4, 8 and 12 werevmore significantly decreased than those before treatment in each group (P ＜ 0.05); the Bath ankylosing spondylitis activity index, pain and spinal pain on a four point Likert scale,overall assessment of patient and physician on a four point scale at week 4and all the indices at week 8 and 12 were more significantly decreased than those in the control group (P ＜ 0.05). ② Evaluation result of Erythrocyte sedimentation rate (ESR) and C reaction protein, Schober test, chest expansion , occiput to wall distance and finger to floor distance: Each index at week 4, 8 and 12 in the experimental group were significantly decreased than those before treatment (P ＜ 0.05), those at week 8 and 12 in the control group were more significantly decreased than those before treatment (P ＜ 0.05). ESR , C reactive protein (CRP) , chest expansion and finger to floor distance at week 12 in the control group were more significantly decreased . ③ Adverse events and side effects: All adverse reactions occurred transiently during the course of disease in the two groups. Undisposed or after having taken live-protective medicine, all patients recovered.Drug was not withdrawn in any case.The incidence of adverse reaction in the experimental group was lower than that in the control group [10％ (3/30),57％(17/30) ,P ＜ 0.05]. CONCLUSION: Combination of total glucosides of paeony, methotrexate and sulfasalazine has an enhanced effect and better safety without special adverse reaction in the treatment of ankylosing spondylitis.

ObjectiveTo investigate the effects of oxidized low density lipoprotein (oxLDL) on autophagy and its effect on Akt/mTOR/p70S6K signaling pathway in human umbilical vein endothelial cells (HUVECs).MethodsThe cultured HUVECs were divided into either an oxLDL or a control group, and treated with 100 μg/ml oxLDL and equal volume phosphate buffer solution respectively.The cells were collected after 6 h and 12 h.Transmission electron microscopy was used to observe the autophagosome.Real-time fluorescence quantitative polymerase chain reaction was used to detect expression levels of microtubule associated protein 1 light chain 3 (LC3) and p62 mRNA.Western blot was used to detect the expression levels of LC3, p62, P-Akt/Akt, P-mTOR/mTOR, and p-p70S6K/p70S6K.Results Compared with the control group, the number of intracellular autophagosome increased obviously (P<0.05), LC3 mRNA and protein expression levels increased significantly (all P<0.05), and p62 mRNA and protein expression levels decreased significantly (all P<0.05) in the oxLDL group.In addition, the phosphorylated protein expression levels of Akt, mTOR and p70S6K in the oxLDL group were significantly decreased than those in the control group (all P<0.01).However, total protein levels of Akt, mTOR, and p70S6K were not significantly different between the oxLDL group and the control group.Conclusion oxLDL may induce the autophagy of HUVECs via inhibiting the Akt/mTOR/p70S6K signaling pathway.

Objective To investigate the treatment outcome of patients with localized soft tissue sarcoma (STS) and related prognostic factors,with a focus of the role of postoperative radiotherapy in the treatment of STS.Methods A retrospective analysis was performed for the clinical data of 203 STS patients who underwent organ preservation surgery in Fudan University Shanghai Cancer Center from July 2000 to July 2010.Of all the patients,76(37.4％) received adjuvant radiotherapy,which was delivered via anterior-posterior parallel opposed fields at a dose of 45-70 Gy.The Kaplan-Meier method was used to calculate survival rates,the log-rank test was used for survival difference analysis,and the Cox proportional hazards model was used for multivariate analysis.Results The follow-up rate was 100％.The 5-year overall survival (OS) rate,local failure-free survival rate,and distant metastasis-free survival rate were 69.1％,69.2％,and 68.0％,respectively.The multivariate analysis showed that pathological subtype,tumor size,resection margin status,and postoperative radiotherapy were influencing factors for OS.Among these factors,postoperative radiotherapy was associated with a significantly reduced risk of local recurrence in STS patients (HR=0.327,95％ CI 0.177-0.605,P=0.000) and a significantly increased OS rate (HR=0.489,95％ CI 0.266-0.897,P=0.021).Conclusions Postoperative radiotherapy can reduce local recurrence and improve OS in patients with localized STS,and further studies are needed to clarify its role.

OBJECTIVE To prep are Legumain enzyme and mitochondrial double-stage targeted harmine （HM） liposome （KA@HM-LPS）and preliminary evaluate its pharmaceutical properties ，in vitro antitumor effect and biocompatibility. METHODS Firstly，the preparation and homogenization methods of KA@HM-LPS was screened ，and prepared liposomes were characterized. Secondly，the serum stability ，in vitro release rate ，hemolysis percentage of KA@HM-LPS and cell survival rate under KA@BLPS were determines respectively. Finally ，the cell surivival rate ，mitochondrial targeting and inhibitory effects on cell migration and invasion of KA@HM-LPS were determined. RESULTS KA@HM-LPS was prepared by the thin-film dispersion method ，with encapsulation efficiency of （90.50 ± 0.62）％ . The extrusion moulding method was selected as homogenization method of KA@HM-LPS. The particle size ，polydispersity index ，and Zeta potential of KA@HM-LPS were （211.40±11.67）nm，0.316± 0.014 and（－14.20±0.49）mV，respectively. In 37 ℃，10％ FBS，the particle size of KA@HM-LPS kept stable after 12 h. In vitro release curve of KA@HM-LPS in 20％ plasma conformed to Weibull distribution and had the property of sustained release. When HM concentration was 160 μg/mL，the hemolysis percentage of KA@HM-LPS was （4.23±0.19）％，which was much lower than that of free HM ，with safety. When the mass concentration of KA@BLPS reaches 400 μg/mL，the survival rate of LO 2 cells was （94.40 ± 6.12）％ ，and the biocompatibility was good. Cell test results in vitro showed that ，inhibitory effect of KA@HM-LPS on liver cancer cells with overexpression of Legumain enzyme （LGMN -SK-Hep-1） was significantly higher than that of normal liver cancer cells SK-Hep- 1； compared with SK-Hep-1，LGMN +-SK-Hep-1 cells had a higher uptake efficiency of the liposome ；KA@HM-LPS could significantly inhibit the migration and invasion of LGMN +- SK-Hep-1 cells. CONCLUSIONS KA@HM-LPS is prepared successfully ，which can effectively inhibit the migration and invasion of liver cancer cells with Legumain enzyme overexpression ，and improve the blood compatibility of HM.
