1. The internal iliac artery was investigated in 100 cases. In 23 cases this arterywas divided into anterior and posterior trunks, while in the remaining 77 cases suchtrunks were absent. 2. The mode of origin of the superior, inferior gluteal arteries and the internalpudendal artery from the internal iliac artery, may be classified into five principal typesand four subtypes. Among them the second type is most frequent (54 cases), the firstand the third type are next in order, their occurrence are 24 cases and 17 cases respec-tively. The fifth type possesses 2 common trunks and occurs in 4 cases. 3. The obturator artery, according to its origin, is divided into three types. Thefirst type, arises from the internal iliac artery, comprises the largest number (81 cases).The second type, arises from the external iliac artery, is next in number (15 cases). Thethird type has two obturator arteries arising from the internal and external arteries (4cases) respectively. 4. The iliolumbar artery arises from the internal iliac artery (54 cases), some fromthe superior gluteal artery (12 cases). 5. The lateral sacral artery, mostly arises from the superior gluteal artery, occursfrom 1--3 branches. There are 2 branches in 43 cases, one branch in 32 and threebranches in 25 cases.

Objective:To observe the effects of double-stranded small interfering RNA (siRNA) of the silent mating-type infor-mation regulation 2 homolog 1 (SIRT1) on the cell proliferation, cell cycle progression, and expression levels of the cell cycle negative regulators. These regulators include P21, P27, and phosphorylated retinoblastoma (PRb) proteins present in prostate cancer PC3 cells. This work further aims to explore the possible underlying mechanism for such effects. Methods:PC3 cells were cultured in vitro and then randomly divided into the mock group, scramble siRNA transfected group, and SIRT1 siRNA-transfected group. SIRT1 siRNA ef-ficiency was examined through reverse transcription polymerase chain reaction and Western blot analysis. The inhibitory rate of PC3 cell growth was determined through a methyl thiazolyl tetrazolium assay, and the cell cycle was investigated with the use of flow cytom-etry. The P21 and P27 protein expression levels and PRb status were determined by Western blot assay. Results:Compared with those of the mock and scramble siRNA groups, the expression levels of SIRT1 mRNA and protein significantly decreased in SIRT1 siR-NA-transfected cells. In addition, the inhibitory rate of PC3 cell growth was markedly increased, and the cell cycle of the PC3 cells was arrested at the G1 stage. The expression levels of negative cell cycle regulators, including P21 and P27 protein levels increased, whereas Rb protein phosphorylation was inhibited in SIRT1 siRNA-transfected PC3 cells. Conclusion: SIRT1 RNA interference inhibits PC3 cell growth and arrests cell cycle progression through the upregulation of the P21 and P27 proteins and the inhibition of Rb protein phosphorylation.

ObjectiveTo seek an effective protocol fortreating spinal cord injury-induced limb dysfunction by comparing the therapeutic effects of electroacupuncture at Huatuo jiaji points plus Du meridian points versus conventional electroacupuncture. MethodForty patients with spinal cord injury-induced limb dysfunction were allocated, using a random number table, to treatment and control groups, 20 cases each. Both groups were treated with ganglioside and routine rehabilitation therapy. In addition,the treatment group received electroacupuncture at Huatuo jiaji points and Du meridian points and the control group, conventional acupuncture. Lower limb function was assessed using ASIA Motor Score, Sensory Score and the MBI in the two groups of patients before treatment and after one and two courses. The clinical therapeutic effects were evaluated.ResultThere was a statistically significant pre-/post-treatment difference in lower limb dysfunction in both treatment and control groups (P<0.05). The improving effect was better in the treatment group than in the control group (P<0.05,P<0.01).ConclusionElectroacupuncture at Huatuo jiaji points and Du meridian points has a definite therapeutic effect on spinal cord injury-induced limb dysfunction. It is superior to conventional electroacupuncture.

Objective To develop models of epileptic discharge by activating group Ⅰ metabotropic glutamate receptors (mGluR) or by blocking gamma-aminobutyric acid (GABA) receptors on rat hippocampal slices. Methods Rat hippocampal slices were exposed to mGluR group Ⅰ specific agonist dihydroxyphenylglycine (DHPG) or to GABAA receptor antagonists bicuculline methiodide(BMI), and single pyramidal cell in the CA3 region of the slice was recorded by whole cell patch clamp technique. Results Exposure to DHPG or BMI resulted in the induction of spontaneously occurring epileptic discharge in the CA3 region of rat hippocampal slice, and there was no significant difference in the frequency of discharge between them(P>0.05). Conclusion Epileptic discharge can be generated in vitro in response to a loss of balance between excitatory and inhibitory influences.

BACKGROUND: Plenty of materials have been used as stent in total auricular reconstruction with varying advantages and disadvantages. The in vitro prepared tissue engineered complex cartilage stent has been not applied in clinic.OBJECTIVE: To observe the ultrastructure changes of surrounding tissues following total auricular reconstruction with nickel-titanium (NiTi) shape memory alloy stent in vivo.DESIGN, TIME AND SETTING: The randomized, controlled, animal experiment was performed in the Central Laboratory of EENT Hospital of Fudan University, Anhui Provincial Hospital and Department of Nuclear Medicine, Huashan Hospital of Fudan University from April 2004 to October 2005.MATERIALS: A total of 12 New Zealand rabbits were randomized divided into the skin-expanded and unexpanded groups, with 6 animals in each group.METHODS: Each animal underwent subcutaneous implantation with a NiTi alloy stent like human auricle. In the skin-expanded group, the stent was implanted after skin expansion, while no treatment in the unexpanded group.MAIN OUTCOME MEASURES: The ultrastructure changes of surrounding tissues were detected by scanning electron microscope at months 6 and 12 after implantation.RESULTS: Structure of nickel-titanium alloy implant stent make fibrovascular ingrowth more easily. The surface of nickel-titanium alloy stent was smooth without corrosion. There was no evidence of infection in the host tissue. Microstructure of Ni-Ti stent wires showed no morphologic and functional changes after subcutaneously implanted in vivo, and the difference between 2 groups had no significance.CONCLUSION: NiTi shape memory alloy stent can smoothly pass the process of fibrovascularization with less complication.According to the examination by SEM, the nickel-titanium stent showed good biocompatibility.

Objective To study the effect of comprehensive care on the level of high-sensitivity Creactive protein and matrix metaloproteinase-9 in patients with hemorrhagic infarction.Methods 48 patients with hemorrhagic infarction were divided into the control group and the observation group with 24cases in each group.The control group was given conventional care,the observation group was given comprehensive care.Serum hsCRP and MMP-9 level of all patients were measured on day 1,day 3,day 7,day 14.Results The level of serum hsCRP and MMP-9 in the observation group on day 7 was significantly decreased compared with on day 1.The level of serum hsCRP and MMP-9 in the observation group on day 7 was lower than the control group.On day 14,the level of serum hsCRP and MMP-9 returned to normal in the observation group,which was lower than the control group.Conluusions The implementation of comprehensive care for HI patients can effectively reduce the hsCRP and MMP-9 level in serum,shorten hospitalization time,and is conducive to the prognosis of patients.

Objective To elucidate the relationship between liver mitochondria calcium content and respi- ratory function in obstructive jaundice and biliary drainage.Methods The model of obstructive jaundice and bil- iary drainage was produced in dogs by common bile duct ligation and choledochoduodenostomy.The liver mitochon- dria were isolated and the calcium content and respiratory control rate were monitored.Results Mitochondria res- piratory control rate and calcium content significantly decreased and elevated respectively after bile duct ligation and there were varying degrees of recovery after biliary drainage,and the degree of recovery was evidently correlated with the duration of obstruction before drainage and the time after drainage.There was a strong negative correlation between the mitochondria calcium content and change of respiratory function.Conclusion The mitochondria cal- cium overload may be one of important factors for suppressed mitochondrial respiration in obstructive jaundice and early relief of the obstruction could favour the recovery of damaged liver mitochondria.
