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.

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 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.

Objective To study CT findings of sacral tuberculosis.Methods CT findings of sacral tuberculosis confirmed pathologically in 13 cases were analysed combined with literature review.Results The S 1～2 tuberculosis was most common.The types of sacrum destruction were osteolytic and bone destruction along the sacral foramen.The cold abscess were distributed at the presacral,unilateral iliac fossa and/or the gluteal region.Three patients(23.1%) were associated with sacroiliac joint tuberculosis(right 2,left 1).Conclusion In the patients with sacral tuberculosis the patterns of sacrum destruction,region of cold abscess and its relationship with the neighboring structures can be well showed by CT,and it can help surgeons to choose the appropriate surgical approach.

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.

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 explore the relationship between diabetic retinopathy (DR) and intima-media thickness in newly diagnosed type 2 diabetic patients. Methods A total of 1236 diabetic subjects who were diagnosed within 1 year, including 218 older patients, were enrolled in the study. Intima-media thickness of the right common carotid artery and femoral artery were determined using B mode ultrasonography. All subjects were ophthalmologically examined. Results The intima-media thickness values of the carotid artery and femoral artery[(0.83 ± 0.11)mm, (0. 80 ±0.11)mm] in elderly DR group were higher than those [(0. 78±0.12)mm, (0.75±0.13)mm] in elderly non-DR group(P＜0.05). The prevalences of DR in IMT≥0.8 mm group[20.6%: carotid artery, 18.6%: femoral artery] were higher than those in IMT＜ 0.8mm group [13.0%: carotid artery, 13.6%: femoral artery] (P＜0. 05). Logistic regression analysis also showed DR was associated with IMT. Conclusions DR is associated with IMT in newly diagnosed type 2 diabetic patients, and early changes of retinopathy are associated with increased IMT.
