Superior Mesenteric Artery (SMA) syndrome is a well-known but rare complication following corrective surgery for scoliosis. It can be easily missed if not thought of in patients presenting with abdominal pain and vomiting post-scoliosis surgery. SMA syndrome is most commonly associated with conditions resulting in significant weight loss but can also occur as a result of biomechanical changes following scoliosis surgery. We present a case of a 13 year-old girl who developed SMA syndrome following scoliosis surgery. A high index of suspicion and early surgical referral are paramount for the successful management of SMA syndrome.

Cerebral infarction is not only a focal damage,but also causes secondary damage in areas remote from the ischemic territory,which will retard the recovery of neurological function.Ephrin receptor B2 (EphB2) plays an important role in the development and repair mechanism of central nervous system.Blocking the effect of EphB2 in brain by using a specific inhibitor may enhance proliferation and migration of endogeneous neuronal stem cells after experimental cerebral infarc- tion,improve neurological function and influence angiogenesis and neuroplasticity in remote sites.It is expected to become a new approach for decreasing damages in areas remote from the cerebral infarction and promoting the recovery of neurological function.

Interleukin-24 (IL-24) is a member of IL-10 family, which was cloned from human melanoma cells by the method of subtractive hybridization. IL-24 can inhibit the growth of tumor cells and angiogenesis and enhance radiation sensitivity and immune adjustment with non-toxic effects on normal cells.As a kind of cytokine with multiple anti-tumor functions, IL-24 will become a new weapon of gene therapy against cancer. The application and mechanism of IL-24 in the treatment of cancer will be discussed in this paper.

Objective:To investigate the clinical, pathological, and prognostic characteristics of luminal B breast cancer patients with diabetes. Methods:A total of 479 luminal B breast cancer patients with diabetes and 3 392 luminal B breast cancer patients without diabetes who were treated between January 2002 and December 2006 were enrolled in this study. The luminal B breast cancer patients were further divided into the luminal B (high ki67) and luminal B (Her-2/neu+) subgroups. Each subgroup was further grouped into metformin-treated, non-metformin-treated, and non-diabetic groups. The indicators included cancer-specific mortality, clinical, pathological stage, lymph node status, chemotherapy, and endocrine therapy. The survival analysis of each group was performed using the Kaplan-Meier method, and the significance was determined using the logrank test. Cox proportional hazard model was used to examine the correlation between each factor and the prognosis. Results:The Kaplan-Meier analysis results revealed that the breast cancer mortality rates in the metformin-treated, non-metformin-treated, and non-diabetic groups were significantly different in both luminal B (high ki67) and luminal B (Her-2/neu+) subgroups (logrank test:P<0.001, P=0.035), and the respective five-year survival rates were 93.5%, 81%, and 89%for the luminal B (high ki67) subgroup and 84%, 77%, and 83%for the luminal B (Her-2/neu+) subgroup. The Cox multifactorial regression analysis results showed that compared with the metformin-treated group, the non-metformin-treated group was associated with a significantly increased risk of mortality (P<0.001, P=0.044) in the two subgroups. Meanwhile, the non-diabetic group was associated with an increased risk of mortality (P=0.038) in the luminal B (high ki67) subgroup only. The percentage of elderly (P<0.001), menopausal (P<0.001), obese (P<0.001), and patients with cardio-cerebrovascular complications (P<0.001) tended to be higher in the metformin-treated and non-metformin-treated groups than in the diabetic group. Moreover, the metformin-and non-metformin-treated groups in the luminal B (high ki67) subgroup were associated with high percentages of T3/4 pathological stage (P<0.001), lymph node metastasis (P=0.001). The non-metformin-treated group was associated with a lower percentage of invasive ductal carcinoma (P=0.001) compared with the other two groups. Conclusion:The non-metformin-treated group resulted in worse clinical outcomes in both subgroups compared with the metformin-treated group. Meanwhile, the non-diabetic group resulted in the worst prognosis among the three groups in the luminal B (high ki67) subgroup. These findings suggest that the choice of different anti-diabetic drugs may influence the prognosis of luminal B breast cancer patients with diabetes.

Objective To establish the subcutaneous transplantation tumor models with Lewis lung adenocarcinoma in C57BL/6 mice, and to observe the influence of oHSV2, DDP and drug combination on tumor volume, median survival time and weight of tumor-burdened mice.Methods Subcutaneous transplantation tumor models were established with Lewis lung adenocarcinoma in tumor-burdened mice.Tumor-burdened mice were randomly divided into the control group, oHSV2 group, DDP group, oHSV2/DDP sequential group, DDP/oHSV2 sequential group and oHSV2+DDP combination group with 12 rats in each group using the random number table method.The tumor size and weight of mice were measured every 3 days.Results On the 21st day, the tumor size of tumor-burdened mice in every group was as follows: control group (1.82±0.06)cm3, oHSV2 group (0.63±0.05)cm3, DDP group (0.58±0.03)cm3, oHSV2/DDP sequential group (0.49±0.05)cm3, DDP/oHSV2 sequential group (0.42±0.04)cm3, and the difference was statistically significant (F=1 359.01, P=0.000).The data in oHSV2+DDP group were put away because of premature death in mice.The differences were statistically significant between control group and oHSV2 group (P=0.000), control group and DDP group (P=0.000), control group and oHSV2/DDP sequential group (P=0.000), control group and DDP/oHSV2 sequential group (P=0.000), oHSV2 group and DDP group (P=0.017), DDP group and DDP/oHSV2 sequential group (P=0.000), oHSV2/DDP sequential group and DDP/oHSV2 sequential group (P=0.001).The weight of tumor-burdened mice in every group was listed as follows: control group (21.64±0.40)g, oHSV2 group (21.34±0.37)g, DDP group (15.96±0.43)g, oHSV2/DDP sequential group (19.04±0.31)g, DDP/oHSV2 sequential group (16.34±0.30)g, and the difference was statistically significant (F=588.67, P=0.000).The difference was not statistically significant between control group and oHSV2 group (P=0.076).However, the differences were statistically significant between control group and DDP group (P=0.000), control group and oHSV2/DDP sequential group (P=0.000), control group and DDP/oHSV2 sequential group (P=0.000), oHSV2 group and DDP group (P=0.000), oHSV2 group and oHSV2/DDP sequential group (P=0.000), DDP group and DDP/oHSV2 group (P=0.013), oHSV2/DDP sequential group and DDP/oHSV2 sequential group (P=0.000).The median survival time of tumor-burdened mice in every group was displayed as follows: control group 23 d , oHSV2 group 32 d, DDP group 30 d, oHSV2/DDP sequential group 37 d, DDP/oHSV2 sequential group 39 d, oHSV2+DDP combination group 16 d, and the difference was statistically significant (χ2=120.81, P=0.000).The differences were statistically significant between control group and oHSV2 group (χ2=10.88, P=0.001), control group and DDP group (χ2=10.69, P=0.001), oHSV2 group and DDP/oHSV2 sequential group (χ2=10.09, P=0.001), DDP group and DDP/oHSV2 sequential group (χ2=9.67, P=0.002).However, the differences were not statistically significant between oHSV2 group and DDP group (χ2=0.00, P=0.996), oHSV2/DDP sequential group and DDP/oHSV2 sequential group (χ2=2.70, P=0.100).Conclusion On the premise of that the weight of mice is no affected, oHSV2 can inhibit the tumor size and prolong the median survival time of tumor-burdened mice effectively, and the effect of DDP/oHSV2 sequential group is the most significant.This article provides an experimental basis for exploring therapeutic methods of lung adenocarcinoma.
