OBJECTIVETo study the effect of total flavanones of Sedum sarmentosum (SSTF) on the apoptosis of rat hepatic stellate cells (HSC-T6) and its mechanism.

METHODDifferent concentrations of SSTF and HSC-T6 cells were co-cultured for different period of time. The MTT assay was used to detect the inhibitory effect of SSTF on the proliferation of HSC-T6 cells. The flow cytometry Annexin-V/PI double staining method was adopted to detect SSTF's effect on HSC-T6 cell apoptosis. Western blotting and Real-time PCR methods were applied to observe the effect on the protein and mRNA expressions of apoptosis-related cytokines Bcl-2, Bax and Caspase-3.

RESULTSSTF significantly inhibited HSC-T6 cell proliferation and induced cell apoptosis in a dose and time dependent manner. According to Western blotting result, SSTF promoted apoptosis by inhibiting Bcl-2, Bax and promoting the protein expression of Caspase-3; according to a further Real-time PCR study, Bcl-2 mRNA levels can inhibit Bcl-2 and promote Bax and Caspase-3 expressions.

CONCLUSIONSSTF has the effect of promoting the apoptosis of HSC-T6 mainly by inhibiting Bcl-2 and promoting protein and mRNA expressions of Bax and caspase-3.

Objective To analyze the clinical features of rectal and perianal inflammatory myofibroblastic tumor and evaluate its diagnosis and treatment.Method Clinicopathological data of 3 cases diagnosed as inflammatory myofibroblastic tumor from January,2005 to June,2011 were retrospectively reviewed.Results Inflammatory myofibroblastic tumor presents as infiltrative growth mass with rich vascularization on CT or MRI,and is difficult to distinguish from hemangioma and other rectal tumors.Preoperative biopsy usually fails to ascertain the entity of mass,and pathological examination of the whole resected specimen with immunohistochemical staining is needed to make final diagnosis.All 3 cases underwent sphincter preserving surgery.One case received a second radical operation 16 months after primary resection because of local recurrence.All patients are followed up to now,with a survival time of 67 months,55 months,and 35 months respectively.Conclusions Rectal and perianal inflammatory myofibroblastic tumor is difficult to diagnose on preoperative imaging examinations or biopsy.Immunohistochemical staining is needed to make final diagnosis.Sphincter preserving surgery with complete tumor removal could achieve long term survival.

Objective To evaluate the endovascular treatment of diffuse aortoiliac occlusive diseases. Methods Thirty-two patients underwent endovascular treatment in which rest pain was found in 84.38%, foot local gangrene in 15.62%. Mean age was 69.7 years (range, 52 years to 81 years) and 71.9% was male. Trans Atlantic Inter-Society Consensus C and D disease was respectively in 40.6% and 59.4% patients. Mean length of vasculopathy was (14.6 ± 1.2) cm (range, 4.5 cm to 19.5 cm) All patients had prohibitive risk for open revascularization. With the approach from femoral artery or brachial artery, combined techniques, such as recanahzation, balloon dilation, stent placement and concomitant common femoral endarterectomy were used. Results Technical success was achieved in twenty-nine patients(90.63%). The complication rate was 3.45%. Clinical status was markedly improved in eight cases (27.59%) and moderately improved in twenty-one cases(72.41%). Mean postoperative ABI was 0.73 ± 0.12, mean preoperative ABI was 0.32 ± 0.09. Significant differences were seen between postoperative ABI and preoperative ABI(P<0.05). Mean time of follow-up was (13.9±6.2) months. At 6 months, primary patency was 81.82% and secondary patency was 89.09%. At 12 months, primary patency was 63.64% and secondary patency was 80.18%. Conclusion Combined multiple endovascular technique is a safe and effective method in the treatment of poor risk diffuse aortoiliac occlusive diseases.

BACKGROUND: There is a close relationship between innervations and bone formation and bone mass maintenance in the extraction sockets. OBJECTIVE:To study the possible effect of denervations on the regulation of new bone formation and bone mass maintenance in the extraction sockets. METHODS:The unilateral inferior nerve of dogs was sectioned to establish an animal denervation model. The normal side was used as control. After model establishment, the premolars of denervated side and normal side were extracted. Histological method was used to test new bone formation and bone mass maintenance in the extraction sockets at the 2nd, 4th, 8th and 12th weeks after tooth extraction. RESULTS AND CONCLUSION:The percentage of new bone areas in the extraction sockets was significantly lower in the experiment group than the control group at weeks 2, 4, 8 after tooth extraction (P < 0.01). The height difference between the buccal and lingual alveolar ridge was higher in the experimental group than the control group at weeks 2, 4, 8, 12 after tooth extraction (P < 0.05 or P < 0.01). These findings indicate that denervation is closely related with new bone formation and bone mass maintenance in the extraction sockets.

Objective To investigate the direct inhibitory effects of 153Sm- DTPA-c (Cys-Gly-Arg-Arg-Ala-Gly-Gly-Ser-Cys) NH2 ( 153 Sm-DTPA-c (CGRRAGGSC)) on human prostate cancer PC-3 cells. Methods 153Sm-DTPA-c(CGRRAGGSC) was synthesized by the reaction of 153SmCl3 with DTPA-c(CGRRAGGSC) using indirect synthesis method. PC-3 cells in vitro culture were divided into four study groups, groug A ( the control, with PBS only), group B with 1.5 mg/L c ( CGRRAGGSC), group C with 370 kBq 153 SmCl3 and group D with 370 kBq 153Sm-DTPA-c(CGRRAGGSC). PC-3 cell growth was assayed by 3-(4, 5-dimethylthiazol-2-yl ) -2, 5-diphenyltetrazolium bromide (MTT) method. Cell cycle and apoptosis were analyzed by flow cytometry. The expression changes of interleukin 11 (IL11 ) and IL11 receptor (IL1 1 R) in PC-3 cells were examined by Western Blot. One way analysis of variance (ANOVA) and paired-t test were applied for statistic analysis. Results The labeling yield of 153Sm-DTPA-c (CGRRAGGSC) was 85% and the radiochemical purity was 95.8%. The specific activity of 153Sm-DTPA-c(CGRRAGGSC) was 1.32 × 105 MBq/μmol. Significant inhibitory effects on the growth of PC-3 cells were found in both group C and D, with a time-dependent manner. However, no obvious inhibition was found either in group A or in group B. After 48 h,significant differences of sub-G1 peak area were found among groups, (0. 98 ± 0. 18)%, (0. 35 ±0. 10)%, (4.05 ±0.28)% and (13.38 ±0. 89)% for group A, B, C and D, respectively. Furthermore,sexpression of ILl 1R in group D was significantly lower than that in group B and C with absorbance values 0. 339 ~ 0.014, 0.338 ~ 0.019, 0.226 ~ 0. 015 for group B, C and D, respectively. Absorbance values in groups B and C were not significantly different after treatment, compared with those before treatment; however, there was difference between absorbance values after and before treatment in group D ( t = 0. 405,1. 163,135.989,P>0.05 >0.05, <0.05). Conchluion 153Sm-DTPA-c(CGRRAGGSC) can directly in hibit the cell growth and expression of human prostate cancer cells PC-3.
