Objective To summarize the advance of bioenergetic metabolic mechanisms of cancer cell. Methods Literatures about the recent studies on the bioenergetic metabolic mechanisms of cancer cell were reviewed.Results Cancer cells required a steady source of metabolic energy in order to continue their uncontrolled growth and proliferation. Accelerated uptake of glucose and glycolysis was one of the biochemical characteristics of hypoxia cancer cells. Glucose transport and metabolism were essential for the survival of tumor cells, leading to poor prognosis. Conclusions The studies on relationships between hypoxia-inducible genes and cancer have come a new understanding of the bioenergetic metabolic mechanisms of cancer cell, become new and important supplementary means of diagnosis and treatment of cancer, and enhanced existing strategies so that the treatment could be more rationally applied and personalized for cancer patients.
Objective To review the latest comparative research of minimally invasive transforaminal lumbar interbody fusion (TLIF) and traditional open approach. Methods The domestic and foreign literature concerning the comparative research of minimally invasive TLIF and traditional open TLIF was reviewed, then intraoperative indicators, length of hospitalization, effectiveness, complication, fusion rate, and the effect on paraspinal muscles were analyzed respectively. Results Minimally invasive TLIF has less blood loss and shorter length of hospitalization, but with longer operation and fluoroscopic time. Minimally invasive surgery has the same high fusion rate as open surgery, however, its effectiveness is not superior to open surgery, and complication rate is relatively higher. In the aspect of the effect on paraspinal muscles, in creatine kinase, multifidus cross-sectional area, and atrophy grading, minimally invasive surgery has no significant reduced damage on paraspinal muscles. Conclusion Minimally invasive TLIF is not significantly superior to open TLIF, and it does not reduce the paraspinal muscles injury. But prospective double-blind randomized control trials are still needed for further study.
ObjectiveTo summarize the autophagy and its research progress in gastric cancer. MethodsIn combination with available literatures published in recent years involving the relationship between autophagy and gastric cancer, the characteristics of autophagy, molecular marker, control factors, and the significance and role in gastric cancer were reviewed. ResultsAutophagy not only promotes cell death, but also can prolong the survival of cancer cells during the tumor formation. Reagents (including traditional Chinese medicine) regulating autophagy have broad prospect of application in cancer therapy, but anti-tumor therapeutic effect based on the regulation of autophagy depends on the actual level of intracellular autophagy. ConclusionThe autophagy in the gastric cancer is still poorly understood, and to clarify the molecular mechanism of autophagy and kill cancer cells by reasonable regulation of autophagy still needs more further in-depth studies.
