To explore the impact of acceleration load on the temporomandibularjoint in aviators and its clinical significance.617 aviators flying aircraft of different types without previous history of temporomandibularjoint disease were studied. Abnormal manifestations of the temporomandibularjointswere analysed. The incidence of temporomandibular joint symptoms was markedly higher in the fighter plane pilots than that in the transportation planegroup. Load induced by acceleration could be one of the main causative factors of temporomandibularjoint disorder.

BACKGROUND: Xiongbitong capsule (capsule) increases blood flow in myocardial ischemic area in patients with coronary heart disease, lessens the size of myocardial infarction and improves ischemic S-T alternation in electrocardiogram (ECG).OBJECTIVE: To observe the effect of the capsule on NO metabolism on arterial wall in rabbits and explore the improvement of such drug on myocardial blood flow and protection on myocardium.DESIGN: Randomized group division and control experiment were designed.SETTING: Department of First Internal Medicine, Hospital of Traditional Chinese Medicine, Weifang, Shandong.MATERIALS: The experiment was performed in Teaching-Research Room of Physiology of Weifang Medical College from April 2003 to February 2004. Totally 30 healthy adult rabbits were employed, of either sex and randomized into 3 groups, named normal control, model group and treatment group, 3 rabbits in each one.METHODS: ① Preparation of hyperlipemia (HP) model: In normal control, common granular forage was used. In model group, modeling forage was applied (common granular forage + 3% pig oil + 1% cholesterol powder). In treatment group, besides modeling forage, at the end of the 6th week, the capsule [composed of taizishen (Radix Pseudstellariae), yunling (Poria), gualou (Frnctus Trichosanthis), qingxia (Rhizoma Pinelliae), juhong (Exocarpium Citri Grandis), shichangpu (Rhizoma Acori Graminei), yujin (Radix Curcumaea), zhifuhua (Flos Inulae), jiangxiang (Lignum Dalbergiae Odoriferae), danggui (Radix Angelicae Sinensis), maidong (Radix Liriopis Platyphyllae) and wuweizi (Frnctus Schisandrae).] was administrated every day for gastric perfusion at 1 pill/kg with 10 mL physiological saline for 3 weeks. The intervention was applied totally for 8 weeks. ② Nitrieoxide synthase (NOS) and NO metabolic product kits were provided from Radiation Medical Institute of Military Academy of Medical Sciences. The operation was based on the instrnction. NOS activity was calculated and expressed by NO amount (nmol) produced in one-gram tissue per minutes.Spectrophotometer was used to measure the optic density of sample at 545nm. Sodium nitrite solution was used to prepare standard curve. The concentration of serum NO metabolic products, NO2- and NO3- was expressed with μmol/L. ③ T test was applied for difference comparison among measurement data.MAIN OUTCOME MEASURES: Comparison of NOS activity and concentration of serum NO metabolic products in vessel-wall tissue in eachgroup.RESULTS: Totally 30 rabbits all entered result analysis. For NOS activity and concentration of serum NO metabolic products in arterial-wall tissue,the results in model group and treatment group were lower remarkably than the control (P ＜ 0.05-0.01) and the results in treatment group were higher remarkably than model group (P ＜ 0.05).CONCLUSION: ① NO system of arterial wall is damaged in HP rabbits and NO metabolic level is decreased in serum. ② Xiongbitong capsule improves the above situation and brings the resistance of myocardial ischemia and protection of myocardium into play.

Objective To investigate the effects of pyrrolidine dithiocarbamate (PDTC) on plasma concentrations of proinflammatory cytokines and myocardial energy metabolism induced by cardiopulmonary bypass (CPB) .Methods Twelve healthy mongrel dogs of both sexes weighing 13.5-17.5 kg were randomly divided into 2 groups (n = 6 in each group) : PDTC group and control group. The animals were anesthetized with intraperitoneal 2.5% pentobarbital sodium 25 mg?kg-1, intubated and mechanically ventilated. In PDTC group PDTC 30 mg?kg-1 was given i.v. after tracheal intubation while in control group normal saline was given instead of PDTC. Aorta was clamped for 60 min and then undamped for 60 min reperfusion during CPB. Blood samples were taken before (baseline), 30 and 60 min after aortic clamping and 30 and 60 min after aortic unclamping for determination of plasma concentrations of TNF-? and IL-1?. Myocardial tissue was obtained before and 60 min after aortic clamping and 60 min after aortic unclamping for determination of myocardial content of adenine nucleotide (ATP, ADP, AMP, TAN, EC) and expression of ICAM-1 protein.Results Plasma TNF-? concentration was increased after aortic cross-clamping as compared to the baseline value before clamping in both groups but the TNF-? concentration was significantly lower in PDTC group than in control group (P

AIM:To investigate the effects of antioxidant N-acetylcysteine(NAC)on the lipopolysaccharide(LPS)-induced MAPK phosphorylation in mouse liver.METHODS:54 male mice were divided into three groups:control(n=6),0.9% sodium chloride 0.2 mL ip;LPS group(n=24):LPS 5 mg ip;NAC+LPS group(n=24):NAC 150 mg?kg-1?d-1 ip,for 3 d;LPS 5 mg ip after 1 h of NAC administration at 3rd day.The liver was excised with carbrital anesthesia after LPS or 0.9 % sodium chloride injection at 0.5 h,1 h,2 h and 6 h for GSH and MDA assays.The protein extracted from liver was assayed for the phosphorylation of MEK1/2,ERK1/2,p38 MAPK by Western blotting.TNF-? in liver was assayed by radioimmunoassay.RESULTS:MDA in the liver was decreased remarkably and the GSH in the liver was increased significantly by NAC pretreatment.The phosphorylation of MEK1/2,ERK1/2 and p38 MAPK in liver were inhibited significantly by NAC pretreatment after LPS challenge.Meanwhile,TNF-? in liver was decreased markedly.CONCLUSION:Reactive oxygen species plays a critical role in MAPK signaling during the LPS induced acute liver injury.NAC partially inhibits LPS-induced MAPK signaling by antioxidant effect and decreases TNF-? production.

Objective To clarify the distribution characteristics of serum pepsinogen (PG ) and gastric cancer related tumor markers in the healthy population ,and analyse their value in health examination .Methods The levels of serum tumor markers ,pep‐sinogenⅠ(PGⅠ ) and pepsinogenⅡ(PGⅡ) were detected in 958 subjects who underwent physical examination by using the Lumi‐nex 200 instrument ,and the ratio of PGⅠ /PGⅡ(PGR) was calculated .Meanwhile ,the C13 breath test was carried out ,and relation‐ships among these clinical indicators were analysed .Results In this population ,The serum level of PGⅠ in male subjects was high‐er than that in female subjects ,there was statistically significant difference(P<0 .05) .The levels of serum PGⅠ ,PGⅡ ,carcinoem‐bryonic antigen(CEA) ,carbohydrate antigen 199(CA199) and carbohydrate antigen 242(CA242) were gradually increased with age ,while the PGR was slowly decreased with age .The positive rate of C13 breath test in male subjects was higher than that in fe‐male subjects ,there was statistically significant difference(P<0 .05) .Compared with subjects whose C13 breath test results were negative ,the serum levels of PGⅠ and PGⅡ were higher ,while the PGR was lower in subjects whose C13 breath test results were positive(P<0 .05) .Conclusion The distribution of serum PG might be correlated with age ,gender and the infection of Helicobact‐er pylori in healthy population .It is shown that the effects of tumor markers on gastric cancer screening are limited .
