Objective To explore the clinical features,diagnosis and treatment of serious pyogenic infection in deep neck.Methods The retrospective analysis was taken on clinical data of 49 cases.They were all with the deep neck space infections.Among them,19 cases were revealed with diabetes,and only 7cases had the treatment history of diabetes before.Results After systemic anti-inflammatory and local symptomatic treatment,the mean course of treatment in patients without diabetes was 10.1 days,and in patients with diabetes was 18.1 days.Conclusion For diabetic patients with more severe neck space infection,in the control of blood glucose under the premise of local treatments and systemic therapy were equally important.

Objective: To observe left and right ventricular mechanical sequence in systole and diastole by dual Doppler Echocardiography in healthy subjects. Methods: Dual Doppler echocardiography was performed in 100 normal subjects with dual-outflow-tract-view and apical four chamber view to simultaneously record the spectrum of left/right ventricular outlfow tract (LVOT)/(RVOT) and left/right ventricular inlfow tract (LVIT)/(RVIT) at the same cardiac cycle. The time cycles of blood lfow spectrum from the peak of QRS complex to aorta, pulmonary artery, mitral valve (MV) and tricuspid valve (TV) were measured, the starting time differences for blood lfow spectrum of aorta and pulmonary artery, MV and TV were calculated to assess the mechanical sequence of left and right ventricle in systole and diastole respectively. Results: There were 48/100 (48%) subjects having LV ejection preceded than RV (95% CI 0.38-0.58), 46 (46%) having RV ejection preceded than LV (95% CI 0.36-0.56) and 6 (6%) having LV, RV simultaneous ejection (95% CI 0.01-0.11). There were 96/100 (96%) subjects having RV iflling prior to LV (95% CI 0.90-0.99), 3 (3%) having LV iflling prior to RV (95% CI 0.01-0.08) and 1 (1%) having LV, RV simultaneous iflling (95% CI 0.00-0.05). Conclusion: There is a regular pattern for mechanical sequence of LV and RV in systole and diastole in healthy subject; in systole, the sequence of LV varies from person to person, while in diastole, RV is always preceded. Based on normal ventricular mechanical sequence, optimizing programming parameter of pace maker and choosing cardiac sequence in diastole might be the ifnal criteria for cardiac resynchronization therapy in the future.

Objective To observe the effects of secreted protein,acidic and rich in cysteine (SPARC) on the expression of TGF-β1 and collagen type Ⅰ in cultured human keloid fibroblasts by real-time fluorescence quantitative RT-PCR.Methods In vitro keloid fibroblasts were stimulated by different concentrations of recombinant human SPARC,and with the control group for comparison,real-time fluorescence quantitative RT-PCR to detect expression of TGFβ1 and collagen type Ⅰ.Results Compared with the control group,the expression of TGF-β1 and collagen type Ⅰ was significantly increased in the experimental group.Conclusions SPARC could enhance the expression of TGF-β1 and collagen type Ⅰ in keloid fibroblasts significantly.

Clinical literature of bronchial asthma treated with acupoints application from January 2000 to March 2014 in modern periodicals databases was retrieved through computer. With cluster analysis and frequency analysis methods of data mining, acupoints selecting and medication rules of bronchial asthma treated with acupoints application were analyzed. Total 38 articles were included eventually, including 25 acupoints and 42 medicines. The results indicate that on acupoints selecting, Feishu (BL 13) is used as the main acupoint and 3 groups of bladder meridian and conception vessel acupoints are applied alternately and on medicines, Baijiezi (Brassica alba Boiss), Xixin (Radix et Rhizoma Asari), Gansui (Radix Kansui), Yanhusuo (Corydalis) and Mahuang (Radix et Rhizonma Ephedrae) are primarily adopted, epispastic medicines being the main medicines; medicines mostly belong to lung meridian, main medicines being unchanged mostly with Shengjiang as guiding drug.

To make a systematic study on acupoints selection and medication rules for allergic rhinitis treated with acupoint application, literature regarding clinical researches on acupoint application for allergic rhinitis since 2000 has been retrieved; medication and acupoints involved were preprocessed and cluster analysis technique was applied to classify the data. As a result, a total of 37 pieces of literature were included, involving 27 types of herbs and 33 acupoints. The results showed Baijiezi (Brassica alba Boiss), Xixin (Radix et Rhizoma Asari), Gansui (Radix Kansui), Yanhusuo (Corydalis), Jiangzhi (Ginger juice) and Baizhi (Radix angelicae) constituted the main herb prescription, and the layer was increased along with frequency of use. Feishu (BL 13), Dazhui (GV 14), Shenshu (BL 23), Pishu (BL 20), Gaohuang (BL 43), Fengmen (BL 12) constituted the main acupoint prescription, which were clustered into 4 classes; Feishu (BL 13) and Dazhui (GV 14) constituted the first class; Pishu (BL 20) and Shenshu (BL 23) constituted the second class; the first and second class merged into the third class, Including Feishu (BL 13), Dazhui (GV 14), Shenshu (BL 23) and Pishu (BL 20); Gaohuang (BL 43) and Fengmen (BL 12) constituted the fourth class; the fourth class and the third class constituted the whole acupoint prescription. It was showed that for the allergic rhinitis treated with acupoint application, the medication was mainly epispastic herbs with pungent nature that belonged to the lung, spleen and kidney meridian, which presented the principle of simultaneous treatment of principal and subordinate symptoms; also the medication can be selected from core layer to supporting layer based on clinical needs; for the selection of acupoints, acupoints in lung and bladder meridian were mainly selected to assist exterior and resist the pathogenic qi, which could treat allergic rhinitis fundamentally by joint use with acupoints in soleen and kidney meridian.

Objective To explore the effect of pulling cervical sympathetic ganglia on blood pressure of experimental rabbit. Methods Anesthetized experimental rabbit were dominated the change of blood pressure with intubation via femoral artery. The electrocardiogram was recorded with standard lead II of electrocardiography, the cervical sympathetic ganglia was separated and the ganglion was ligated, with 20 g quality to the ventral top force, then the blood pressure was recorded and analyzed. Results Before pulling, the blood pressure maintained at 110/80 mmHg, and during the process of separating the neck nerve, the blood pressure increased temporarily. During pulling cervical sympathetic ganglia, it decreased about 20 s and then increased gradually and maintained at 125/90 mmHg until the end of pulling. Conclusion Pulling cervical sympathetic ganglia could significantly increase the blood pressure of experimental rabbit.
