The activation of oncogenes occured in most tumors,and is believed to play an important role in tumorigenesis. However,the activation of oncogenes could induce cellular senescence in wild type cells,known as oncogene-induced senescence (OIS). Thus,the activation of oncogenes has the dual role in inducing cellular senescence or tumorigenesis. DNA damage checkpoint response (DDR) is the molecular signal transduction pathway that delay or arrest cell cycle progression in response to DNA damage and is an important molecular mechanism that induce cellular senescence. Activation of oncogenes could produce DNA damage signals and initiate DDR,which subsequently induce cellular senescence. However,when DDR pathway is deficient,activation of oncogenes could induce unlimited DNA hyper-replication and cellular hyper-proliferation,which results in accumulation of genome instability,and tumorigenesis ultimately. Therefore,the dual role of activated oncogenes is regulated by the integrity of DDR pathway. The key role of DDR in regulating activated oncogenes indicates that maintain or restore the integrity of DDR pathway might provide a new strategy in cancer prevention and therapy.

Objective: To observe the clinical efficacy of electroacupuncture (EA) plus long-snake moxibustion for rheumatoid arthritis (RA) due to kidney deficiency and cold coagulation. Methods: A total of 60 patients in active stage of RA were randomly divided into an observation group and a control group, with 30 cases in each group. Patients in the control group took methotrexate tablets and nimesulide dispersible tablets orally for treatment, while those in the observation group received additional treatment of EA plus long-snake moxibustion. Both groups were treated for 12 weeks. The post-treatment changes in symptomatic grading and quantifying score, disease activity score with 28 joint counts (DAS28), and inflammatory indicators erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were observed, and the efficacy was evaluated. Results: The total effective rate in the observation group was 89.9％, versus 76.6％ in the control group, and there was a significant difference in the total effective rate between the two groups (P<0.05). After treatment, the symptomatic grading and quantifying score and DAS28 in both groups were significantly improved (all P<0.05), and the improvements in the observation group were more significant than those in the control group (both P<0.05). Besides, there were 11 cases with low disease activity index (DAI) and in remission in the observation group versus 5 cases in the control group, showing a statistically significant between-group difference (P<0.05). The ESR and CRP scores in both groups were significantly reduced after treatment (all P<0.05), also showing statistically significant between-group differences (both P<0.05). Conclusion: The efficacy of additional EA plus long-snake moxibustion based on oral medications for RA due to kidney deficiency and cold coagulation is better than that of the oral medications alone.

Nowadays, for gait instability phenomenon, many researches have been carried out at home and abroad. However, the relationship between plantar pressure and gait parameters in the process of balance adjustment is still unclear. This study describes the human body adaptive balance reaction during slip events on slippery level walk by plantar pressure and gait analysis. Ten healthy male subjects walked on a level path wearing shoes with two contrastive contaminants (dry, oil). The study collected and analyzed the change rule of spatiotemporal parameters, plantar pressure parameters, vertical ground reaction force (VGRF), etc. The results showed that the human body adaptive balance reaction during slip events on slippery level walk mainly included lighter touch at the heel strikes, tighter grip at the toe offs, a lower velocity, a shorter stride length and longer support time. These changes are used to maintain or recover body balance. These results would be able to explore new ideas and provide reference value for slip injury prevention, walking rehabilitation training design, research and development of walking assistive equipments, etc.

Human mammaglobin (hMAM) is a recently discovered breast tissue specific protein with a high sensitivity and specificity. The expression of hMAM in breast cancer and its relationship with breast cancer indicate that hMAM is a novel breast specific marker that can induce cytotoxic actions from immune system and therefore may have great potentials in breast cancer treatment.

Objective To compare the clinical efficacy and safety of continuous subcutaneous insulin infusion (CSII) and multiple subcutaneous insulin injection (MSII) in elderly patients with severe type 2 diabetes.Methods Thirty-seven elderly patients with severe type 2 diabetes in the hospital intensive care unit (ICU) were divided into observation group (19 cases) and control group (18 cases) by random number table method.The observation group was treated with continuous subcutaneous insulin recombinant human insulin lispro injection,and control group was treated with recombinant human insulin lispro injection before meals and at bedtime routine insulin glargine subcutaneous injection.Two groups of patients and their families were given diabetes education.Changes in blood glucose,insulin dosage,blood glucose control standard time,rate of hypoglycemia and hospitalization time between 2 groups before and after treatment were compared.Results After treatment,fasting blood glucose in observation group was (7.2 ± 1.2) mmol/L,2 hour postprandial blood glucose was (9.4 ± 1.2) mmol/L,bedtime blood glucose was (9.4 ± 1.3) mmol/L; which in control group was (8.5 ± 3.0),(10.0 ± 2.4),(10.2 ± 2.4)mmol/L respectively.Fasting blood glucose,2 hour postprandial blood glucose and bedtime blood glucose significantly decreased after treatment in two groups,but there was significant difference between 2 groups (P ＜ 0.05).Blood glucose control standard time in observation group was (5.4 ± 2.5) d,insulin dosage was (43 ± 9) U/d,in control group was (12.8 ± 3.8) d,(55 ± 10) U/d respectively,and there was significant difference (P ＜ 0.05).Observation group had no hypoglycemia.Conclusion CSII for elderly patients with severe type 2 diabetes has better curative effect and security than MSII,and is more conducive to the control of blood glucose and the improvement of the condition.

SIGIRR, a member of the interleukin 1 receptor superfamily, is also known as a single immunoglobulin (Ig)-related receptor, which is believed to play a key role in the development of inflammation and the regulation of anti-inflammatory effects. Some studies believe that the abnormal down-regulation of SIGIRR can lead to intestinal inflammation, pyelonephritis, systemic lupus erythematosus and other diseases, but it can promote tumor growth and potentially cause anti-tumor immune damage when its genes are overexpressed. Therefore, the role of SIGIRR in disease occurrence and development is considered a double-edged sword. At present, the detailed molecular mechanism of SIGIRR′s biological role is not fully understood. This article reviews the functions of SIGIRR in the occurrence and development of immune-related diseases and immune regulation, as well as related cell signaling pathways, which have been discovered and confirmed.
