Neoplastic stem cells (NSCs)are the source of tumor occurrence and development,and its special microenvironment is involved in tumor drug resistance,recurrence and metastasis by regulating NSCs or changing itself. Eradicating NSCs and interfering the special microenvironment may be the new therapeutic strategies for cancer.

Objective To evaluate the safety and efficacy of OUR Rotating Gamma System in neurosurgical clinical application. Methods Based on the results of animal experiments, 2381 patients with intracranial disease were treated using OUR Rotating Gamma System in Aohai Gamma Knife Center of Navy General Hospital of PLA betwean December 1996 and November 2002. There were 1288 males and 1093 females and their age ranged from 3 to 84 years (mean 45.8 years). 1020 patients had benign intracranial tumors, and of them 446 suffered from pituitary tumors, 254 meningioma, 148 craniopharyngioma and 103 vestibular schwannomas. Malignant tumors were diagnosed in 796 patients, among them glioma was found in 360 and metastasis in 360. 374 patients had cerebral arteriovenous malformations (AVMs) and 191 functional neurological disorders. Treatment technique of Gamma Knife Stereotactic Radiosurgery, dose prescription and precise orientation performed in intracranial tumor or foci were analyzed, and the preliminary outcome of treatment was evaluated in this study. In addition, the management of the possible complication and adverse reaction was studied. Results Gamma Knife Stereotactic Radiosurgery alone, or combined with other treatment procedures, could cure some of selected patients with benign brain lesions including pituitary neoplasms, meningioma, vestibular schwannomas, AVMs, and craniopharyngioma etc. And this treatment was also beneficial to some patients with malignant tumors. The incidence of radiation edema was 0.75%. Conclusions The clinical results suggest that Gamma Knife Stereotactic Radiosurgery is a very effective, accurate and relatively safe neurosurgical tool used either as a primary or adjuvant procedure for treatment of intracranical pathologic processes. However, it might lead to some severe or fatal complications if used inappropriately. Thus, optimal result would not be obtained unless a careful and precise Gamma treatment based on the operative rules and the effective management for postoperative complications are well planned.

Objective To explore the effects of oxidative stress in the pathogenesis of lung injury and observe the influence of N-acetylcysteine (NAC). Methods The lung histopathology was observed by light microscope. The level of 8-iso-prostaglandin F2?lpha (8-iso-PGF2?) in blood plasm were measured by ELISA. The difference of 8-iso-PGF2? in blood plasm in air group, different dose NAC groups between hyperoxia-model and the air group was compared. Results In hyperoxia-model group, the inequality of size of lung alveoli, hemorrhage and inflammatory cell infiltration in lung alveoli were observed on the 3rd and 7th day. The alveolar septum was thick in the hyperoxic-damaged lungs on the 14th and the 21st day. In hyperoxia+high-dose NAC group, very small amounts of red blood cells leaked out into alveoli on the 3rd and 7th day and alveolar septum had no thickening obviously on the 14th day and the 21st day. The level of 8-iso-PGF2? in blood plasm in hyperoxia-model group [(28.33?5.57) pg/ml, (51.21?15.01) pg/ml, (84.54?14.85) pg/ml and (43.14?11.37) pg/ml at every time points] was higher than that of the air group and hyperoxia+high-dose NAC group(P

Evidence based medicine is medicine based on evidence and the application of evidence based medicine to laboratory medicine is evidence based laboratory medicine. The major enforcement strategies of evidence based laboratory medicine include: discovering problems and bringing them forward; seeking valuable evidence from the laboratory or relevant literature; making experimental or methodological assessments; application in the practice of clinical laboratory; and evaluating the results of the practice. Evidence based medicine and evidence based laboratory medicine are of great significance to the advancement of laboratory medicine and clinical work.

Objective To study the Ile796Val polymorphism in human SCAP gene in Hubei area, and analyze its correlation with coronary heart disease (CHP) and hypertension and the relationship between polymorphism and lipid metabolism. Methods Using PCR RFLP, we detected genotypes of Ile796Val polymorphism in human SCAP gene. Results The allele A frequencies of Ile796Val in human SCAP gene for controls, CHD patients and the hypertension patients were 0.32, 0.45 and 0.42 respectively. The allele G frequencies were 0 68, 0.55 and 0.58 respectively. There were significant differences in frequencies of genotype and alleles between controls and hypertension group. And there was significant difference in the level of TC, LDL C and ApoB. In CHD group, there was significant difference in the TC level between different genotypes. In hypertension patients, although a difference was noted in genotype, there was no significant difference in allele frequencies and lipid level exceps a significant difference in the levels of TC, LDL C and ApoB in hypertension patients. Conclusion Ile796Val polymorphism in human SCAP gene may be a great agent to cause disorder in the lipid level of blood and lipid metabolism of tissue. It is of great significance in disorder in lipid metabolism of inter cellular and genetic investigation of hyperlipidemia.

Objective To study the relation between Jiegeng loading drug up in Tianwang Buxin Wan and brain,heart and lung.Method 32 Wister rats were randomly divided into four groups(8 rats in each group),namely,control group,Jiegeng group,Tianwang Buxin Wan group,Tianwang Buxin Wan lacked Jiegeng group.The levels of cyclic nucleotide in the brain,heart and lung were assayed by radioimmunoassay.Result The levels of cAMP in the lung in every drug group were significantly increased compared with that of control group.It was significant on the level of cAMP in the lung between Tianwang Buxin Wan group and Tianwang Buxin Wan lacked Jiegeng group.Conclusion It was the lung that linked the effect of Jiegeng loading drug up in Tianwang Buxin Wan.

Sepsis is a high-risk factor for the death of critical patients. High density lipoprotein (HDL) are the major protective serum proteins, and the serum levels of HDL are closely related to the severity of sepsis. The anti-inflammatory and anti-oxidation properties of HDL, may be able to play an important role in the innate immune response. Thereby it may reduce the damage of septic shock and multiple organ dysfunction syndrome (MODS) in animals or human beings, and improve the prognosis. In order to unveil the metabolism of HDL in septic patients and its effects on both progression and prognosis of sepsis, this review not only focuses on the composition and structure of HDL, but also analyzes its pivotal role in inflammatory immune response and anti-oxidation.
