Epistaxis is a common otorhinolaryngological emergency with complex etiological factors and varied clinical manifestations. The key to epistaxis treatment is accurate diagnosis and adequate hemostasis. Electrocoagulation is a reliable, safe and effective treatment for epistaxis. However, there are still several deficiencies in application of the commonly used electrocoagulation surgical products. This paper introduces a new type of radiofrequency head incorporating the dynamic circulatory functions of drip, irrigation, hemostasis and aspiration. We aim to achieve noninvasive, effective and accurate hemostasis in the treatment of epistaxis or nasal sinus surgery.

The statement on the depth of needle insertion is collected from Neiiing (nternal Classic) and Nanjing (Classic of Medical Problems) and the relationship of it is discussed with meridians, diseases, symptoms, location of sickness, qi and blood changes in human body, time, layers of needle insertion, reinforcing and reducing of acupuncture, etc. The factors are explored for the determination of the puncture depth, which provides the important guidance for the depth of insertion, needling sensation, reinforcing and reducing manipulations, acupuncture effect and the improvement of acupuncture efficacy. The complex and mystery of acupuncture technique focus on the control of insertion depth. In clinical practice, the increase of needle insertion depth may not induce the equal increase of efficacy. The depth of needle insertion is rather relevant with stimulation at the effective acupoint in the effective layer.

Objective To observe the clinical efficacy of acupuncture by selecting points from the Lung and Stomach Meridians based on the theory of accumulation in stomach and connection with lung in treating post-infectious cough.Method Ninety patients with post-infectious cough were randomized into treatment group 1, treatment group 2, and a control group. Treatment group 1 was intervened by acupuncture at points from the Lung and Stomach Meridians, treatment group 2 was by puncturing points from the Lung Meridian, and the control group was by oral administration of Compound Methoxyphenamine Capsule. Leicester Cough Questionnaire (LCQ) was adopted for observation before and after intervention, and the symptom and clinical efficacies were compared between the groups.Result The total effective rate was 90.0% in treatment group 1, versus 83.3% in treatment group 2, and 80.0% in the control group. The total effective rate of treatment group 1 was significantly different from that in treatment group 2 and the control group (P<0.05). Regarding cough during the daytime, the total effective rate was 93.3% in treatment group 1, versus 83.3% in treatment group 2 and 76.7% in the control group. The total effective rate in treatment group 1 for cough during the daytime was significantly different from that in treatment group 2 and the control group, and the total effective rate in treatment group 2 was significantly different from that in the control group (P<0.05). For cough at night, the total effective rate in treatment group 1 was 86.7%, versus 80.0% in treatment group 2 and 80.0% in the control group. The total effective rate in treatment group 1 for cough at night was significantly different from that in treatment group 2 and the control group (P<0.05). The LCQ score in treatment group 1 was markedly different from that in treatment group 2 and the control group (P<0.05).Conclusion Acupuncture based on lung-stomach theory is an effective approach in treating post-infectious cough, and this method has an advantage of general regulation.

Objective To observe the biological characteristics and analyse primary therapeutic response of acute erythroid leukemia.Methods The data of 28 patients primarily diagnosed as acute erythroid leukemia were analyzed.The patients were divided into with muhilineage dysplasia group and without muhilineage dysplasia group,and the morphology,immunology,cytogenetics and molecular biology characteristics and the complete remission rate of the first induction therapy were compared.Results There were 14 cases(50％)with muhilineage dysplasia,which involved in two lineage or trilineage.In 6 cases by flow cytometry,the myeloid blast immunophenotypes were common expressed.In 8 cases detected by karyotype analysis,5 cases were chromosomal abnormal,including 4 cases were complex chromosomal abnormal,1 case was trisomy 8.In 4 cases underwent WT1 detection,all of them were positive.The complete remission rate of the first induction therapy was 39.29％(11/28),the ratein the multilineage dysplasia group was 35.71％(5/14),and the ratein without multilineage dysplasia group was 42.86％(6/14),the difference had no statistical significance(P＞0.05).The complete remission rate of the complex chromosome group was 25.00％(1/4),the intermediate prognostic group was 50.00％(2/4).Conclusions Acute erythroid leukemia had special biological features different from other subtype AML:accompanyed with high frequency of multilineage dysplasia.The abnormality of karyotype were high,and it was often complex karyotype involved with chromosome 5 and/or chromosome 7,which had a low complete remission rate.The complete remission rate of chemotherapy was low,treatment effect was poor.

BACKGROUND:The combination of fiber post and resin core for restorations of mesial or distal defects of the maxil ary central incisor can restore the elastic modulus close to the nature dentin, and achieve good aesthetic effects. However, when a complete dentin col ar cannot be prepared due to a large number of dental tissue defects, the post and core are easy to be lost or fractured after defect repair using the combination of fiber post and resin core.
OBJECTIVE:To compare the stress distribution after nickel-chromium cast post and core, gold-pal adium cast post and core, and fiber post and resin core were used for restorations of mesial or distal defects of the maxil ary central incisors using three-dimensional finite element analysis.
METHODS:An intact adult maxil ary central incisor that meets the average dental anatomical value in China was selected and scanned using a dental cone-beam CT. Then, three-dimensional tooth-fiber post and core (nickel-chromium cast post and core or gold-pal adium cast post and core)-al-ceramic crown models of mesial or distal defects of the maxil ary central incisors and part loss of dentin col ar were established using ABAQUS analysis. After repair with nickel-chromium cast post and core, gold-pal adium cast post and core, and fiber post and resin core, stress distribution in the loaded state was compared using the ABAQUS three-dimensional finite element analysis.
RESULTS AND CONCLUSION:The stress peak at the adhesive and cast layers in the fiber post and resin core group was significantly lower than that in the nickel-chromium cast post and core or gold-pal adium cast post and core group. It indicated that the tooth root was easy to be fractured after mesial or distal defects of the maxil ary central incisors with partial loss of dentin col ar were restored with nickel-chromium cast post and core, gold-pal adium cast post and core. In addition, the stress peaks at the dentin layer were consistent for fiber post and core, nickel-chromium cast post and core, and gold-pal adium cast post and core. These findings indicate that the combination of fiber post and resin core is better for restorations of mesial or distal defects of the maxil ary central incisors.

BACKGROUND:Many researches on the development of cochlea have been made, but mainly depend on the pathological conditions and developmental deformity, while the researches on the development process of normal embryonic cochlea and expression of related factors are rare.
OBJECTIVE:To investigate the expression of transforming growth factorβ1 in rat embryonic cochlea.
METHODS:Fifty-six Sprague Dawley rats were selected and the rats were pregnancy, and the embryos were obtained from the rats, trimmed the inner ear specimens under the anatomical microscope, and then the specimens were treated with dehydration, decalcification, directly paraffin embedding and slicing processing. The morphology evolution of inner cochlea was observed under light microscope after hematoxylin-eosin staining. The expression of transforming growth factorβ1 in rat embryonic cochlea was observed by immunohistochemical streptavidin biotin-peroxidase complex method.
RESULTS AND CONCLUSION:The development of rat inner ear began in ectoderm thickening area of E8 phase, otocyst and the emergency of the mesenchymal could be seen in E9 phase, otocyst and ossicular chain began to develop in E9.5 phase, formation of cochlear duct anlage could be seen in E12.5 phase, cochlea tube development was completed in E18.5 phase and Corti’s formation could be seen in E16 phase. The structure and function of the inner ear could be ful y developed after birth. The expression of transforming growth factorβ1 could be seen in E12.5-E19 phases, and the expression was changed from weak to strong and then weakened further, and strongest in E14.5 phase. This suggested that transforming growth factorβ1 may be involved during the development of rat cochlear epithelium.
