Chinese Journal of Pathophysiology 1986;0(01):-
AIM: To observe the pathological role of 3-nitrotynosine (3-NT) on Escherichia coli LPS-induced vascular hyporeactivity in rats and the therapeutic effect of antioxidants. METHODS: Forty male SD rats weighting from 200 g to 250 g were randomly divided into four groups: the control group (n=10); LPS shock group (n=10); uric acid-treated group (n=10); melatonin-treated group (n=10). 6 h after LPS shock, phenylephrine (0.5-2.5 ?g?kg -1) was applied intravenously to all groups and the percentage increase in MAP was detected, respectively. The concentration-response curve of aorta rings from all groups rats were obtained by cumulative addition of phenylephrine (PE), and PE E_ max, EC_ 50 were calculated. The concentrations of plasma malondialdehyde (MDA), nitrate/nitrite and 3-NT were assayed in all groups 6 h after LPS shock. RESULTS: The MAP level induced by PE significantly decreased to 54.60% in LPS shock rats compared with the control (P

International Journal of Biomedical Engineering 2014;37(2):115-118
Objective To summarize and classify the CT manifestations of chest wall tuberculosis and to investigate the relationship between CT classification and clinical operation method.Methods CT data of 142cases was collected from patients that were confirmed by surgical pathology of chest wall tuberculosis.Bone algorithm reconstruction and volume rendring three-dimensional reconstruction were applied to observe ribs.Results Four types were classified according to the CT manifestations.Type Ⅰ:27 cases pleural tuberculoma,and all of which were conducted simple removal of lesions.Type Ⅱ:18 cases sternum or ribs tuberculosis,which were conducted surgical removal of the invaded frame and the surrounding lesions in caseous necrosis and all the tuberculous granuloma.Type Ⅲ:21 cases rib outboard tuberculosis,of which 12 cases were conducted simple removal of lesions and 9 cases removal of lesions and small segment of ribs.Type Ⅳ:76 cases hybrid,of which abscess excision plus rib resection in 65 cases and resection with chest wall abscess (muscle) between ribs and rib resection with padded muscle flap surgery in 11 cases.Conclusions CT can clearly show the location,size,scope of involvement of the chest wall tuberculosis,and selecting the preoperative surgical strategy based on CT classification can provide guidance for operation.
5.Comprehensive geriatric assessment and its clinical impact in oncology
Journal of International Oncology 2014;41(5):332-334
With the aging of the population,management of cancer in the elderly aged people represents a priority for health care.However,fewer evidence-based data are available to promote the treatment of these patients.Comprehensive geriatric assessment (CGA) is developed recently as a multi-disciplinary in-depth evaluation to assess life expectancy and risk of morbidity from cancer in elderly patients,which is helpful for physicians to develop a coordinated plan for cancer treatment and to provide appropriate interventions to decrease the risk of morbidity and mortality.
6.Microtubule-destabilizing protein stathmin—a new target for gene therapy of cancer
China Oncology 1998;0(01):-
Stathmin is a novel member of microtubule-destabilizing proteins that play a critical role in the regulation of the dynamic equilibrium of microtubules during different phases of the cell cycle.The overexpression of stathmin was found in different type of cancer.Inhibition of stathmin expression in malignant cells may interfere with their orderly progression through the cell cycle.Overexpression of stathmin can affect the action of antimicrotuble drugs by markedly decreasing binding of paclitaxel,and increasing binding of Vinca alkaloids.In addition,stathmin provides an attractive molecular target for cancer therapy.It may be possible to combine adenovirus-mediated anti-stathmin ribozyme therapy with a chemotherapeutic agent such as taxol to obtain a more potent antiproliferative and antitumor effect.

Journal of Xi'an Jiaotong University(Medical Sciences) 2003;0(06):-
Objective To study the clinical and THR?gene mutation of two cases of pituitary thyroid hormone resistance. Methods The clinical data and peripheral blood samples of the patients and their family members were collected, and then DNA was isolated. PCR and direct sequencing techniques were performed to determine if there were mutations in their THR?gene. Results No mutation was found in exon 1-10. Conclusion Pathogenesis of sporadic pituitary resistance to thyroid hormone usually has no relation with mutation of THR?gene.
8.Effects of antioxidant on the gene expression of ?_1-adrenergic receptors during endotoxic shock in rats
Chinese Journal of Anesthesiology 1995;0(02):-
Objective To investigate the effects of antioxidant on the gene expression of ?1-adrenergic receptors (AR) during endotoxic shock. Methods Forty male SD rats weighing 200-250 g were anesthetized with intraperitoneal (i.p.) pentobarbital. The animals kept spontaneous breathing. Femoral artery and vein were cannulated for BP monitoring and drug administration. The animals were randomly divided into 5 groups ( n = 8 each) : (1) control group; (2) LPS group received IPS 15 mg?kg-1 i.v. ; (3) LPS + propofol group received at 1h after LPS a bolus of propofol 10mg?kg-1 i.v. followed by continuous infusion of propofol at 10 mg?kg-1?h-1; (4) LPS + uric acid (UA) group received uric acid 200 mg i.p. 1 h after LPS and (5) LPS + melatonin (MLT) group received MLT 10 mg?kg-1 i.p. 1h after LPS. The animals were killed at 6 h after LPS. Total RNA was extracted from the heart, aorta, vein, lung, liver and kidney. ?1A-,?1B-,?1D- AR mRNA and ?-actin mRNA were measured using reverse transcription polymerase chain reaction (RT-PCR) .Results The expression of ?1A-AR and ?1B-AR mRNA in all the organs and the ?1D-AR mRNA expression in aorta, liver, lung and kidney were strongly down-regulated in LPS group. In group 3 (LPS + propofol) the expression of ?1A-AR mRNA in the lung and kidney, the ?1B-AR mRNA expression in all of the organs and ?1D-AR mRNA expression in aorta, liver, lung and kidney were significantly increased as compared with LPS group. There was no significant difference in ?1-AR mRNA expression between LPS group and LPS + MLT group. The expression of ?1A-AR mRNA in kidney, the ?1B-AR mRNA expression in all of the organs except the lung and the ?1D-AR mRNA expression in aorta, liver, lung and kidney were significantly higher in LPS + UA group than in LPS group. Conclusion Circulatory failure induced by endotoxic shock is related to the down-regulation of ?1-AR gene expression. The therapeutic effects of antioxidant on the endotoxic shock is partly due to up-regulation of ?1-AR gene expression.
