Objective To investigate effects of mini-invasive treatment for patients with vascular malformations in oral and maxillofacial region . Methods 8 cases with vascular malformations in oral and maxillofacial deep or special region were injected pingyangmycin into vein lake by color ultrasound-guided needle aspiration. Results All cases were cured and no facial nerve was damaged. Follow-up ranged from 6 months to 1 year, and no recurrence was found. The vascular malformations of 4 cases in maxillofacial deep region were disappeared or instead of fiber tissue with MRI detection 6 months after treatment. Conclusions Injecting pingyangmycin by color ultrasound guided-needle aspiration for patients with vascular malformations in oral and maxillofacial deep or special region is effective, safe and mini-invasive treatment.

Objective to observe the effect of lung and spleen mixture on lung spleen deficiency AECOPD with Ⅱ respiratory failure of TCM symptoms integral,nutrition,blood gas and related indicators.Methods in accordance with AECOPD with Ⅱ type of respiratory failure need to use the noninvasive or have a respirator assisted ventilation,and conform to the type of TCM for patients with spleen-deficiency type,40 cases were divided into two groups,control group to the conventional western medicine therapy and Chinese medicine group on the basis of western medicine treatment for reasons of Yifeijianpi mixture,oral or tube feeding,a week for a period of treatment,observation of patients before and after treatment of TCM symptoms and physical signs integral,APACHE Ⅱ score,serum albumin,pre-albumin,neutrophil percentage,CRP and blood gas analysis and related indicators was conducted.Results The results show that the TCM group can improve the patients' TCM symptoms and physical signs integral,there was significant difference between the two groups after treatment (P＜ 0.05);compare the serum albumin,pre-albumin,transferrin,neutrophil percentage,CRP and arterial blood gas between two groups of patients after treatment,Chinese medicine group is superior to the control group,with statistical significance (P＜ 0.05);And compared with control group,the APACHE Ⅱ improvement situation of Chinese medicine group were superior to control group after the treatment after a week,with statistical significance (P＜ 0.05).Conclusion on the basis of using conventional western medicine treatment,treatment based on the theory of ridging raw gold formulae of Yifeijianpi mixture has good effect in the treatment of AECOPD combined type Ⅱ respiratory failure,and can improve the nutritional status of patients and the indicators of arterial blood gas analysis.

ObjectiveTo explore the morbidity rate of deviation of nasal septum about personnels who take part in physical examination in the enterprise and facilities of Qinhuangdao,and clinic symptom.MethodsTransverse questionnaire investigation and normal physical examination were adopted.2604 personnels who take part in physical examination were choiced.ResultsMorbidity rate of deviation of nasal septum was 17.6％.The rate of men' s exceeds that of women' s.ConclusionMorbidity rate of deviation of nasal septum was rather high,clinic symptom of snuffle was primary.

Zebrafish was selected as model animal, and glucocorticoid dexamethasone was used as a model compound to establish a rapid and high efficient osteopenia model. Zebrafish larvae at 4 days post fertilization (dpf) were exposed to a serial concentrations of dexamethasone solutions, and 0.5% DMSO was selected as the vehicle control group. All groups were incubated in 24-well plates (28.5 degrees C) until 9 dpf. In addition, effects of 10 micromol x L(-1) dexamethasone on preventing against osteopenia induced by etidronate disodium were also investigated. Zebrafish bones at 9 dpf were stained with alizarin red. Quantitative analysis of the stained area was performed by microscopic inspection and digital imaging methods to reflect the amount of bone mineralization. Results showed that dexamethasone group at 2.5, 10 and 25 micromol x L(-1) can decrease the staining area and the staining optical density values of zebrafish head bones when compared with the vehicle control group (0.5% DMSO), which suggested that dexamethasone can significantly reduce the zebrafish mineralized bone and the bone mineral density. Results also showed that 15 and 30 microg x mL(-1) etidronate disodium can increase the mineralized matrix of zebrafish head bone and prevent against osteopenia induced by dexamethasone. In conclusion, the study indicated that zebrafish can be an idea osteopenia model induced by dexamethasone.

Objective To investigate the effect of different bone cement volume injected after vertebroplasty on stress distribution of the upper and lower endplates of the injured vertebra in the flexion and extension positions by finite element analysis.Methods Two patients with osteoporotic compression fractures of L2 vertebral body were chosen.Bone cement volumes of 25％ and 50％ were respectively injected into the fractured vertebral body bilaterally.Pre-and post-operative finite element models of fractured and adjacent vertebral bodies were developed after extracting the CT data.Stress changes at L2 superior-and inferior-vertebral endplates were observed in the vertical,flexion,and extension loading.Results Stress at the upper and lower endplates of the fractured vertebra increased after bone cement injection and more increase was observed in 50％ bone cement group than in 25％ bone cement group.In the neutral position,the stress mainly concentrated at posterior vertebral body,with stress of the upper endplate improving from 0.91 × 106 N · mm to 0.93 × 106 N · mm and stress of the lower endplate from 0.98 × 106 N ·mm to 1.03 × 106 N · mm.In the anterior flexion,the stress mainly concentrated at anterior vertebral body,with stress of the upper endplate improving from 4.44 × 106 N · mm to 5.55 × 106 N · mm.In the posterior extension,the stress mainly concentrated at medial vertebral body,with stress of the upper endplate improving from 21.95 × 106 N · mm to 22.10 × 106 N · mm and stress of the lower endplate from 30.60 ×106 N · mm to 30.88 × 106 N · mm.The finite element model revealed stress at the upper and lower endplates was higher in the anterior flexion and posterior extension than in the neutral position,while in the anterior flexion the stress was comparatively higher.Conclusions A small amount of implanted bone cement act no evident effect on stress distribution of the upper and lower vertebral endplates.However,the stress changes are significant as cement volume reached up to 50％,especially in the flexion position,as may suggest an enhanced risk of adjacent intervertebral disc degeneration and adjacent vertebral body fractures.

Objective To investigate the changes and clinical significance of calcitonin gene related peptide (CGRP) and interleu-kin 1α(IL-1α) before and after warm acupuncture therapy in the patients with lumbar disc herniation (LDH ) .Methods Serum CGRP and IL-1αcontents were detected before and after the warm acupuncture therapy in 60 cases of lumbar disc herniation and 15 healthy control cases by ELISA method for conducting the statistical analysis .The changes of the McGill pain scores and serum CGRP and IL-1αconcentrations before and after the warm acupuncture therapy were observed .Results The McGill pain scores af-ter the warm acupuncture therapy in the LDH patients were significantly decreased ,the difference was statistically significant (P<0 .01) ,and serum CGRP and IL-1α concentrations were significantly decreased ,the difference was statistically significant (P<0 .01) .Conclusion CGRP and IL-1αcan be used as the observation index of the effects for the warm acupuncture therapy in trea-ting LDH ,which can provide the basis for the conservative treatment of LDH .
