ObjectiveTo investigate the personal or clinical characters of those traumatic brain injury (TBI) patients who accept rehabilitative therapy in the past decade.Methods280 inpatients were observed and evaluated at admission. Database was then established. ResultsThe average age was (33.1±11.4), and the ratio of male to female was 4.28:1. 34.6% of them were office-bearer, and 71.1% of all could gain the socialized medicine. Of the cause, 66.4% were traffic accidents. The time between date of onset and date of admission ranged from 10 days to 6 years, with average 288 days, and only 25.0% patients was admitted less than 3 months after onset. Of them all, 15.7% were diagnosed as posttraumatic seizure and 18.9% as dropsy of brain.ConclusionThe main TBI patients in our hospital were male citizens who had socialized medicine. Too less patients can accept rehabilitative therapy during acute or subacute periods after onset.

Objective To observe the protective effects of natural antioxidant tea polyphenols(TP) on myocardial free radical metabolic disorder in mice induced by inhalation of hypobaric pure oxygen under 5500 m hypobaric condition. Method Fourty-two male Kunming mice were randomly divided into three groups(n=14 each):group A, normal control; group B, inhalation of pure oxygen(>96%) at simulated altitude of 5500 m in an animal altitude chamber;group C(TP protection group), same as group B but 100 mg/kg of TP was given orally before the exposure. The exposure time was 2 h/d,3 d/wk for a total of 8 wk, and distilled water was given to groups A and B before exposure. After experiment, the mice were decapitated on the next day and the heart was quickly removed. Malondialdehyde(MDA) concentration, superoxide dismutase(SOD) activity and nitric oxide(NO) content were measured. In addition, Cu,Zn-SOD and inducible NO synthase(iNOS) enzymatic contents in myocardial tissue were qualitatively examined by immunohistochemical assaying. Result Compared with the control, MDA concentration, SOD activity and Cu,Zn-SOD enzymatic content in group B were significantly increased(P<0.05).But in TP protection group, myocardial MDA formation was significantly decreased(P<0.01) and SOD activity and Cu,Zn-SOD expression restored to normal. On the contrary, myocardial NO generation and iNOS expression were significantly reduced after repeated inhalation of hypobaric oxygen at 5500 m.NO metabolism regained to normal after repeated administration of TP. Conclusion Natural antioxidant TP had protective effects on myocardial free radical metabolic disorder induced by inhalation of hypobaric pure oxygen under 5500 m hypobaric condition.

Objective To study and observe the effect of astragalus membranaceus on serum free amino acids and chemokines in patients with rheumatoid arthritis. Methods 60 patients with rheumatoid arthritis in Lishui Hospital of traditional Chinese medicine from October 2014 to May 2016 were selected as the research object,and 60 patients were divided into control group and observation group with 30 cases in each group,according to the method of random number table,the control group were treated with conventional treatment of rheumatoid arthritis,the observation group were treated with astragalus mongholicus on the basic of control group,then the serum free amino acids and chemokines of two groups before the treatment and at 10th,20th,40th and 60th day after the treatment were respectively detected and compared. Results The serum free amino acids and chemokines of two groups before the treatment were compared, while the serum chemokines of observation group at 10th,20th,40th and 60th day after the treatment were all lower than those of control group,the serum free amino acids glutamic acid,asparagic acid and phenylalanine were all lower than those of control group,leucine,γ-aminobutyric acid, glycine and taurine were all higher than those of control group,the difference was statistically significant (P<0.05). Conclusion The influence of astragalus mongholicus for the serum free amino acids and chemokines of patients with rheumatoid arthritis is better,so its application in the patients with rheumatoid arthritis is higher.

Objective To investigate the effects of amyloid-β (Aβ)25-35 on endoplasmic reticulum (ER) stress and apoptosis in cultured rat cardiomocytes,and to elucidate the role of ER stress in the injury of cardiomocytes induced by Aβ25-35.Methods The isolated rat myocardial cells were cultured in vitro.Following stimulation of Aβ25-35 with different dose,the survival ratio was observed with methyl thiazolyl tetrazolium (MTT) method.Hoechst33258 staining was used to observe the morphology of apoptotic changes.The percentage of apoptotic cardiomyocytes was quantified with flow cytometry.The expressions of ER stree proteins,including X box-binding protein-1 (XBP-1),glucose-regulated protein 78 (GRP78),and CCAAT/enhancer-binding protein homologous protein (CHOP) were measured with Western blot.The cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase (PARP) were measured with Western blot.Results Aβ25-35 decreased the survival ratio and induced the apoptosis of cultured rat cardiomocytes in dose-dependent mode.Meanwhile,Aβ25-35 increased the expressions of ER stree proteins,including XBP-1,GRP78,and CHOP.Aβ25-35 increased the expressions of cleaved caspase-3 and cleaved PARP.Conclusions Aβ25-35 could induce the apoptosis of rat cardiomyocytes,which were involved in ER stress possibly.This study might provide a new strategy for clinical treatment of Alzheimer's disease (AD)-associated myocardial injury.

Objective To evaluate the results of endovascular intervention for infrapopliteal arterial occlusion in 40 patients. Methods There were 41 affected limbs in these 40 patients receiving 44 times of endovascular intervention for infrapopliteal arterial occlusion during Nov. 2006 and Dec. 2007. The average age was 76±6. The ABI(ankle brachial index)before intervention was 0.39±0.20 in anterior tibial artery and 0.39±0.23 in posterior tibial artery. CLI (critical limb ischemia) was 80.49% (33/41). Results The after intervention ABI increased by 0.43±0.22 (P<0.01) in anterior tibial artery and 0.43±0.25(P<0.01)in posterior tibial artery. 35 patients (36 limbs) were followed-up for (6±3) months. The limbs of Fontaine Ⅰ and Fontaine Ⅱ A were 28 (77.78%), CLI decreased to 19.44% (7/36) (P<0.01). At follow-up the ABI in anterior tibial artery was 0.63±0.22 and 0.56±0.22 in posterior tibial artery. The difference were all significant when compared with that before intervention and after intervention. The perioperative amputation rate was 0. The perioperative mortality rate was 2.5%. The total mortality rate was 15%. The limb salvage rate were 100%. Conclusion The effect of endovascular intervention for infrapopliteal arterial occlusion is satisfactory.

Monoamine oxidase(MAO) is a kind of mitochondrial outer membrane enzyme that degrades biogenic amines,such as catecholamine and serotonin.It has a variety of biological functions,and can be found in various human tissues,including nervous system.Two MAO enzymes,MAO-A and MAO-B have been identified.MAO gene has polymorphisms,and some of which have a close relationship with certain psychic diseases,such as major depression,alcoholism,antisocial personality disorder and so on.MAO gene can acts as a new forensic individual identification and parentage testing genetic marker or legal psychiatry testing referential genetic marker.

ObjectiveTo investigate long-term outcome after severe traumatic brain injury (TBI) with or without posttraumatic seizure (PTS). Methods225 inpatients of severe TBI were analyzed retrospectively, with parts of them followed up for 2~5 years after injury.Results31 cases (13.8%) were diagnosed as PTS. All the PTS patients and 66 TBI patients without PTS were followed up. There were lower scores of quality of life index (QLI) in PTS patients (5.23±2.25) than those without PTS (7.05±2.28).ConclusionThere was a worse long-term outcome in TBI patients with PTS.
