In order to explore the cellular mechanism of antishock effect of anisodamine (654-2), the changes of intramitochondrial magnesium during late hemorrhagic shock were observed. Results showed that there exists a negative correlation between the blood plasma magnesium concentration and arterial blood pressure in shocked animals and at the same time the magneium content of liver mitochondria reduced significantly; 654-2 prevented the decrease of mitochondria magnesium and the increase of blood plasma magnesium, and improved the prognosis of the shocked animals. These results indicate that 654-2 may protect the liver mitochondria of shocked animals at a cellular and subcellular levels.

Tension-free hernioptasty is a major method for treating inguinal hernia, characterizing by less wound, tension-free incision, sample processing, less dissection and separation, mild pain, rapid recovery, and short length of stay. In particular, transabdominal preperitoneal inguinal hernioplasty is considered as the most ideal method at physiologicoanatomical level. However, the effect of patch materials on postoperative recovery is generally ignored for a long time. Recent studies demonstrate that patch weight and mesh diameter are important factors for abdominal wall repairing and reconstruction. Polypropylene patch, characterizing by strong stability, high intensity, great unreactiveness, and sample processing, has become a major material for hernioptasty. However, there are still some problems of clinical application, including that polypropylene patch may induce intensive foreign body reaction and chronic inflammation as well as compliance decreasing of abdominal wall. Therefore, polypropylene patch should be chosen according to patient requirement, i.e., light, soft, and wide-aperture patch, so as to reduce onset of complication. Nerve and ligament tissues could be clearly observed from light and soft patch, and this might and prevent hurt by mistake, improve repairing operability, enhance correct putting of patch, and decrease incidence of pain. Furthermore, the structure was beneficial for in-growth of fiber tissue, longitudinal and transversal movement induced by body position alternation and muscle contraction, and reduction of discomfortableness.

With the development of modem tumor diagnostic techniques and therapies, the survival rate of malignant tumor has been remarkably increased. With the increase in survival rate of cancer-beating patients, the chance of tumor metastasis is elevated. Minimally invasive treatment provides a new strategy to the therapy of spinal metastatic carcinoma. Its benefits include smaller surgical wound,, higher efficacy and fewer complications, and thus have a broad application prospects in the field of spinal metastatic tumors. In this article, a general re-view is given on minimally invasive treatments of spinal metastatic carcinoma, as well as the latest progress in the field. It was proposed that the united application of the treatment might be a promising hot spot of tumor therapy.
