Thyroid fine needle aspiration biopsy, ultrasonographically guided thyroid fine needle puncture and the common cytologic pathological characterstics of various thyroid diseases are reviewed, and the clinical application is discussed.

The article reviews primary, secondary and tertiary prevention strategy of thyroid diseases and its possible effect.

Congenital central hypoventilation syndrome,also known as “Ondine′s curse”,is charac-terized by hypoventilation during sleep and impaired ventilatory responses to hypercapnia and hypoxemia. This disorder is associated with a malfunction of the nerves that control involuntary body functions and abnor-mal development of early embryonic cells that form the spinal cord. This review summarized the latest pro-gression in the pathogenesis,clinical symptoms,diagnosis,treatment and prognosis.

OBJECTIVE:To optimize the extraction of effective ingredients and purification for crude glycyrrhizic acid and liquiritin from Radix et Rhizoma Glycyrrhizae with different methods. METHODS:The contents and extraction percentages of glycyrrhizic acid and liquiritin were used as indexes to optimize the extraction solvent. Then the extraction process was optimized with orthogonal experiment taking the concentration of ammonium ethanol,the amount of solvent and the extracting times as indexes. Crude glycyrrhizic acid was purified with the method of recrystallization and crude liquiritin was purified with organic solvent method.RESULTS:The optimal extracting solvent was ammonium ethanol. The optimum extraction conditions were as follows:extracting the solvent 4 times(2 h/time) by adding 5 times volume of 60% ethanol(containing 0.3% ammonia water). The purity of glycyrrhizic acid was over 85% with total extraction rate at 43%,and content of liquiritin was above 15% with its total extraction rate at 67%. CONCLUSION:The method is simple and feasible and from which glycyrrhizic acid and liquiritin was been obtained,Radix et Rhizoma Glycyrrhizae can broaden the scope of the application.

Neonatal fungal infections include superficial skin infections and deep fungal infections.Fungal infection is more common during the neonatal period,which is related with newborns(especially premature children),low birth weight and immune dysfunction.In addition,long-term application of broad-spectrum antibiotics and adrenal corticosteroids also induce fungal infections.Severe or disseminated fungal infection can lead to serious illness and even death.Neonatal fungal infections usually show no special clinical manifestations,and can thus result in the delayed diagnosis and treatment.This article discussed the pathogenic species of fungal infection and the risk factors.

Objective To investigate the expression of serum interleukin-2(IL-2),tumor necrosis factor-α(TNF-α)in the pa-tients with pulmonary tuberculosis and diabetes,and prelininary explore its clinical significance.Methods Experiment were divided into control group(health check-up outpatient,n=10),pulmonary tuberculosis group(n=20),diabetes group(n=20),tuberculosis combine diabetes group(n=20),tuberculosis combine diabetes group was divided into improved group,diabetes group and deterio-rated group after 2 months with therapy according to disease outcome,ELISA assay was used to measured the level of serum IL-2 and TNF-α.Results Before treatment:serum IL-2 levels of pulmonary tuberculosis group,diabetes group and pulmonary tuberculo-sis combine diabetes group were reduced (P<0.05),and the pulmonary tuberculosis group was lower than the pulmonary tubercu-losis group and diabetes group (P<0.05);serum TNF-αlevels of pulmonary tuberculosis combine diabetes group,pulmonary tu-berculosis group and diabetes group increased (P<0.05),and that of pulmonary tuberculosis combine diabetes group was higher than that of diabetes group (P<0.05).After treatment:the level of serum IL-2 increased and TNF-αsignificantly decreased in pul-monary tuberculosis combine diabetes improved group (P<0.05),the deterioration group had no change(P>0.05).Conclusion IL-2 and TNF-αplay a role in the immune pathogenesis of tuberculosis combine diabetes,which dynamic changes can reflect the progression and outcome of pulmonary tuberculosis combine diabetes.

Presently, with the development of tissue engineering technology, medical workers have seen a more effective and safer therapy to repair and reconstruct tissue defects. Many domestic and abroad animal experiments have confirmed that it is feasible, effective and superior to use tissue-engineered bone and cartilage for repairing tissue defects. There have been achieved considerable results using tissue-engineered bone and cartilage to repair tissue defects and reconstruct tissue functions through the animal experiments and initial clinical studies. Compare with traditional operations, tissue engineering technology has a broader clinical application, especially in orthopedics, department of stomatology, cranio-facial surgery and ear, nose and throat, department. However, through the research, we recognize some deficiencies of tissue engineering, such as single tissue components, lack of biological activity, limited for scaffolds, tissue regeneration and productions.
