Objective To explore the imaging features and clinical significance of solitary costal hot spots on bone scintigraphy (BS). Methods Eighty-four patients with single costal hot spots were enrolled in the study. The sites of lesions were classified into four types: junction betweenaor rib. The shapes of hot spots were classified into three forms: Punctiform, clumping and strip. The above data were respectively analyzed. Results Single hot spots were mainly showed in the punctiform and strip shapes, and the distribution of punctiform spots were mainly in the sites of junction between costal cartilage and rib and frontal ribs, also mainly due to costal fractures (42/61, 68.85%). The majority of spots in strip shape were costal metastases(18/19, 94.74%). Hot spots in posterior ribs were also mainly costal metastases (24/29,82.76%). Conclusion Useful imaging features can be obtained from BS with al diagnosis of benign and malignant lesions.

Objective To explore the curative effect of local oxygen therapy in combination with external application of Houfengsan and vitamin AD mixture in the treatment of red breech. Methods 100children with red breech were divided randomly into the treatment group and the control group with 50 cases in each group. The treatment group was treated with direct local oxygen blowing for 10～15 minutes and applying mixture of Houfengsan and vitamin AD, the control group was treated with 3% zinc oxide unguent.The treatment effect and cure time were compared between the two groups. Results The total efficient rate of the treatment group was 100% ,which was higher than that of the control group. The cure time of the treatment group was (3.92±0.98) days ,and (6.66t1.46) days in the control group, and the difference was significant between the two groups. Conclusions Local oxygen blowing with external application of mixture of Houfengsan and vitamin AD is easy to accept by children, safe, economical and simple to operate. It is an effective method to treat red breech.

BACKGROUND: Metabotropic glutamate receptor(mGluR) is G-protein coupled membrane receptors, which participate in various physiology or pathology process in brain, but how it induce brain ischemic tolerance(BIT)is unclear.OBJECTIVE: To study roles of mGluR2/3 and mGluR1/5 in the BIT induction.DESIGN: Randomized controlled study based on experimental animals.SETTING: Neurological department of provincial hospital and pathophysiological department of basic institute in a university.MATERIALS: The study was conducted at the Pathophysiological Department, Institute of Basic Medicine, Hebei Medical University from May 2002 to May 2003. Totally 64 healthy male SD rats were selected from the Experimental Animal Center of Hebei Medical University. Glial fibrillary acidic protein (GFAP) antibody, MTPG and(s)-4C3HPG were got from Sigma Company.INTERVENTIONS: 4 vessel occlusion(4VO) brain ischemic models in rats stained with thionine staining and GFAP immunohistochemistry staining. were used. Sixty-four rats, of which bilateral vertebral arteries were occluded permanently by electrocautery, were divided into the following 8groups: sham operation group, cerebral ischemic preconditioning(CIP)group, ischemic insult group; BIT group; MTPG + sham operation group;MTPG+BIT group; MTPG+ischemia group and(s) -4C3HPG+BIT coup. All the rats were killed 7 days after the operation or the final ischemic treatment. Cerebral sections were selected and stained with thionine staining and GFAP immunohistochemistry staining.MAIN OUTCOME MEASURE: The changes of the morphologic hippocampal pyramidal cell and GFAP expression of astrocyte.RESULTS: ① The 8 minutes ischemic insult increased the histological grade(HG) in CA1 area, decreased the pyramidal neuronal density(ND)and increased the expression of GFAP significantly( P ＜ 0.05) . ② The above changes were not observed in the BIT group, indicating that the CIP could protect pyramidal neurons against the 8-minute ischemic insult. ③The protective effects of the CIP were blocked by MTPG or(s)-4C3HPG, as manifested by significant increases in HG and decreases in ND in the groups of MTPG + BIT, MTPG + ischemia and(s)-4C3HPG + BIT( P ＜ 0.05).CONCLUSION: MTPG or (s) -4C3HPG could block the induction of BIT induced by CIP, but mGluR2/3 or mGluR1/5 could participate in the induction of BIT by which protect effect of mGluR is further induced.

Objective To carry out bacteriological analysis between re-used and disposable oxygen humidification devices. Methods Reused oxygen equipment and disposable oxygen moisture bottles from 6 randomly selected elderly wards were collected, patients who used oxygen will be randomized into 3 groups, group A used cold water as the oxygen humidification liquid, group B used distilled water as humidification liquid, group C used AQUAPAK disposable oxygen humidification devices, sample taking in group A and group B happened on every Monday and Thursday before the replacement of sample moisture bottles, sample was taken in group C after the use of disposable oxygen humidification devices, according to "hospital disinfection health standards" (GB5982-1995)sampling method of disinfection liquid sample was taken and sent to test in the disinfectant laboratory. Results Of 61 samples in group A bacteria cartier rate was 81.97%, bacteria carrier rate of 71 samples in group B was 47.89%, of 52 samples in group C the carrier rate was 0. The comparing of bacterial contamination rate of three kinds of oxygen moisture bottles after using was statistically significant. Take group A, B for comparison, the average severity level of bacteria in group A is higher than group B. In group A, the level of the Gram-negative bacteria as well as Gram-positive bacteria colonization was higher than group B. Conclusions Whether use of cold water or distilled water, oxygen humidification liquids have different degrees of pollution. Currently there is no general criteria and norms in the context of sterilization of oxygen humidification, for patients on long-term oxygen using, to choose disposable oxygen humidification device to reduce the incidence of hospital infections is recommended.

AIM: To explore the role of NO in the induction of brain ischemic tolerance (BIT) by observing changes of NOS activity and NO_2-/NO_3- content following a transient cerebral ischemia. METHODS: The rat 4-vessel occluding brain ischemic model was used. 140 male Wistar rats were divided into sham, cerebral ischemic preconditioning (CIP), ischemic insult and CIP+ischemic insult groups. An occlusion of the 4 vessels for 3 min was normally used as CIP, and a relative long one for 10 min was used as ischemic insult. When CIP was followed by ischemic insult, the interval between them was 3 d. The CA1 region of the hippocampus of rats was dissected out at 0 h, 2 h, 16 h, 24 h, 36 h, 72 h and 7 d after the last time of ischemia to assay its NOS activity and NO_2-/NO_3- content. RESULTS: The NOS activity and NO_2-/NO_3- content began to increase at 16 h, peaked at 24 h and decreased to basal level at 36 h of reperfusion after CIP. The duration of the up-regulation of NOS activity and NO_2-/NO_3- content was much shorter than that of BIT, which usually takes place 1-7 d after CIP. The pattern of upregulation of the NOS activity and NO_2-/NO_3- content was similar to the CIP group, but the maximum (24 h) was much more than that in CIP group (P
