Objective To summarize the experiences in clinical diagnosis and surgical treatment of chest cancers invading the superior vena cava (SVC). Method Retrospective study of 12 cases with chest cancers invading the SVC, SVC and innominate vein were reconstructed with prosthesis in 3 cases, the side wall of the SVC was excised and repaired in 9 cases. Results Complete resection was performed in 10cases,2 cases had incomplete resection. There was no death associated with operation in these patients. All patients were followed up for 1 - 7 years after operation,and 3 cases were lost to follow up,5 of remaining 9cases were dead because of relapse and metastasis, their median survival time was 8 months,other 4 cases lived, their median survival time was 42 months. Conclusions Patients with chest cancers invading the SVC should have surgical treatment of not only tumor resection but also the vessel reconstruction,the prognosis would be better than without surgical treatment. These patients have a high quality of life and live with long-term survival.

BACKGROUND:Human leukocyte antigen (HLA), the major histocompatibility complex of human, plays an important function in the transplant rejection. Decreasing the expression of HLA wil prolong the survival time of transplants.
OBJECTIVE:To design smal interfering RNA (siRNA) of HLA-A2 and to detect the effect of siRNA-HLA-A2 on the expression of HLA-A2.
METHODS:Four kinds of siRNA-HLA-A2 domains were designed, and recombinant lentivirus expression vector were formed. The 293T cells, highly expressing HLA-A2, were infected in vitro. Then the knockout efficacy of four domains was detected to select the highly efficient siRNA-HLA-A2 target sequences. The human embryo lung fibroblasts were cultured in vitro and infected with the lentivirus carrying the target sequence. The infecting efficiency of LV-siRNA-HLA-A2 was observed under the fluorescence microscope and the silence function of this siRNA in human embryo lung fibroblasts was detected by western blot analysis.
RESULTS AND CONCLUSION:According to the mRNA sequence of HLA-A2 in Genbank, three siRNAs were designed and synthesized. In vitro, the over expression of HLA-A2 in 293K cells was successful y silenced. The HLA-A2 expression in human embryo lung fibroblasts was also efficiently silenced after the human embryo lung fibroblasts were infected by the highly efficient siRNA of HLA-A2. The efficacy was up to 80%.

Objective To observe the anti-atherosclerosis effects of Guizhi Fuling Capsule. Methods 50 healthy SD male rats were randomly divided into 2 groups: normal group (n=12) and AS model group(n=38). The model of experimental AS rats was established by feeding high cholesterol diet and intraperitoneal injecting VitD3. The normal control group was fed by ordinary diet. AS model group was further divided into 3 groups randomly: AS group(n=12), control group (n= 12), and therapy group(n= 12). The therapy group was given Guizhi Fuling Capsule by intragastric administration.The control group was given simvastatin and captopril by intragastric administration. 0.9% NaCl was given to the AS group instead of Guizhi Fuling Capsule. The rats were killed at the 16th weekend, and their aorta arch and breast aorta were observed.Blood fat and serum levels of Endothelin-1 (ET-1), Nitric oxide (NO), high-sensitivity C-reactive protein (hs-CRP) were detected respectively. Immunohistochemistry technology was used for observing the expression of intercellular adhesion molecule- 1 (ICAM- 1 ) in breast aorta. Results The values of ET- 1, NO, hs-CRP and the amount of ICAM- 1 were (142.61 ±25.67)ng/ml, (66.05 ± 8.63) μmol/L, (2.86±0.40)mg/L, (0.29±0.05) in the normal group; (182.38±22.96)ng/ml, (28.70±4.49)μmol/L, (5.60±0.49)mg/L, (0.58±0.06)in the AS group; (154.37±21.11)ng/ml, (45.88±11.36)μmol/L, (3.66±0.34)mg/L, (0.37±0.04)in the control group and (152.13±23.23)ng/ml, (57.67±8.96)μmol/L, (3.70±0.40)mg/L, (0.36±0.04) in the therapy group respectively. The levels of ET-1, NO, hs-CRP and the amount of ICAM-1 have significant difference between the AS group and the normal group(P=2.47E-4, 6.02E-19, 1.11E-12, 2.51E-18). There was also significant difference between the control group and the AS group(P=0.005, 1.59E-14, 1.87E-5, 3.87E-14). The level of NO in the therapy group was higher than that in the control group (P=0.002). The levels of ET-1, hs-CRP and the amount of ICAM-1 did not have significant difference between the therapy group and the control group(P=0.81, 0.81, 0.48) Conclusion Guizhi Fuling Capsule has effects of Anti-atherosclerosis on rats with AS.

Objective To study the effect of recombinant human edostatin on peritoneal angiogenesis in uremic peritoneal dialysis(PD) rats. Methods Forty male SD rats were randomly divided into 5 groups: normal control rats (group 1), renal failure without PD rats (group 2), rats dialyzed with 4.25% PD solution (group 3), rats dialyzed with 4.25% PD solution and received subcutaneous injection of recombinant human endostatin 10 mg/kg (group 4), rats dialyzed with 4.25% PD solution and received subcutaneous injection of recombinant human endostatin 40 mg/kg (group 5). Recombinant human endostatin was given every other day during peritoneal dialysis period, total 14 times. After regular PD for 28 days, tissue immunohistochemical staining and RT-PCR were used to detect the mRNA and protein expressions of VEGF and bFGF in peritoneal tissues of each group rats. Microvessel density (MVD) of peritoneum was detected and quantified with anti-CD34 immunohistochemical staining. Results The mRNA and protein of VEGF and bFGF were expressed in each group. Compared to group 1, the mRNA and protein expression of VEGF and bFGF were significantly up-regulated in group 2 and group 3 (all P＜0.05). Compared with group 3, the mRNA and protein expression of VEGF and bFGF were significantly downregulated in group 4 and group 5 (all P＜0.05). Compared with group 4, the mRNA and protein expression of VEGF and bFGF were significantly down-regulated in group 5 (all P＜0.05). The new microvascular vessels in group 1 showed little or none. Compared with group 1, MVD was significantly increased in group 2 and group 3 (P＜0.05). Compared with group 3, MVD was significantly decreased in group 4 and group 5 (all P＜0.05). Conclusions Recombinant human endostatin can effectively inhibit rat peritoneal neoangiogensis. Down-regulated expression of VEGF and bFGF in peritoneum may be one of the mechanisms of recombinant human endostatin inhibiting peritoneal angiogenesis.
