This paper introduces the perioperative nursing of 20 cases of branchial cysts in newborn with cyst extraction. The nursing care focused on body position,respiratory care,diet management and wound care,which alleviated the patients' dyspnea,prevented respiratory aspiration and promoted wound healing. All the 20 newborn recovered well without recurrence in the four years after the operation.

0.05), indicating that the functional reserve of PRL, TSH and ACTH cells were normal in IGHD patients. Except the ratio of peak and basal level, all the other five indices of the LH response to LHRH were significantly lower in IGHD patients than in normals of puberty. The functional reserve of LH cell was low in about 2/3 IGHD patients. These results might explain the delayed or no puberty in adult IGHD patients.

Objective: To observe the effects of Astragalus injection, astragaloside IV and formononetin on proliferation and Akt phosphorylation of basal-like human breast carcinoma cell lines MDA-MB-468 and MDA-MB-231. Methods: The effects of different concentrations of Astragalus injection, astragaloside IV and formononetin on proliferation of breast cancer cell lines were assayed by methyl thiazolyl tetrazolium (MTT) assay, and their effects on phospho-Akt were assayed by in-cell Western blot method. Results: The results of the MTT assay showed that the best concentrations of Astragalus injection, astragaloside IV, formononetin and astragaloside IV plus formononetin were 1 g/mL, 80 mug/mL, 40 mug/mL and 10 mug/mL plus 40 mug/mL respectively. After 1- or 2-day culture, Astragalus injection, astragaloside IV, formononetin and astragaloside IV plus formononetin decreased the expressions of p-Akt (Thr 308) and p-Akt (Ser 473) in MDA-MB-468 cells. Formononetin and astragaloside IV plus formononetin down-regulated the expression of p-Akt (Thr 308) protein in MDA-MB-231 cells after 1- and 2-day culture, but had no effects on the expression of p-Akt (Ser 473) protein in MDA-MB-231 cells. Conclusion: Astragalus injection, astragaloside IV and formononetin can inhibit proliferation of breast cancer cell lines MDA-MB-468 and MDA-MB-231, and the antiproliferation effects vary according to their concentrations. And the antiproliferation mechanisms may be related to their down-regulation effects on Akt phosphorylation.

Acute liver failure (ALF) in children is severe syndrome with varied etiology and a rapid deterioration of liver function which results in coagulopathy abnormality and encephalopathy.ALF in children often carries a high morbidity and mortality.Laboratory tests is helpful for diagnosis and severity assessment of ALF in children and is useful for predicting survival or need for liver transplantation.The objective of this article is to introduce the values of laboratory tests in clinical diagnosis,prognosis and timing for transplantation of ALF in children.

The association between autoimmunity and lymphoma is bidirectional: patients with autoimmune disorders have an increased risk of developing malignant lymphoma, and autoimmune symptoms occur in the context of malignant lymphoma much more often. The epidemic features, clinical characteristics,and biologic mechanisms that underlie this association have been investigated in many studies, and this review is focused on recent progresses in this area.

With the development of medicine and health,the experts who have a good command of medicine and law are in great social need,so the major of medical law was introduced.This article,based on the experience and construction of medical law major in Kunming Medical College,put forward that the major of medical law must establish the cultivation goals curriculum system and projects of internship.It emphasizes the approaches to improving the students' knowledge of Arts and comprehensive abilities.

Eukaryotic cells maintain cellular homeostasis by regulating the process of protein degradation and organelle turnover.Autophagy is a ubiquitin-like degradation process,and plays an essential role in cellular development,differentiation,and elimination of damaged organelles and protein.Previous studies mostly focused autophagy on tumor and neurodegenerative diseases,whereas studies about autophagy and energy remain not clear.Since 2009,an increasing number of studies have showed light on the importance of autophagy in regulating lipid metabolism.The review focuses on the relationship between autophagy and differentiation of adipocytes,lipogenesis,and lipolysis.

Objective To study the correlations between diopter,axis length,cornea curvature and thickness in myopia patients. Design Prospective case series.Participant 300 myopic patients who were ready for LASIK.Method 300 myopic patients who were ready for LASIK were selected randomly.They were divided into four groups according to the diopter of myopia:low myopia group (≤-3.00D)41 cases,medium myopia group(＞-3.00D,≤-6.00D)130 cases,high myopia group(＞-6.00D,≤-9.00D)95 cases,and super myopia group(＞-9.00D)34 cases.The axis length,cornea thickness,cornea eurvture and diopter of myopia were detected. Through analysis of variance(ANOVA),Pearson correlation analysis and linear regression analysis,the correlations between axis length, cornea thickness,curvature and diopter of myopia were made out in four groups.Main Outcome Measure Diopter of myopia,cornea curvature,axis length of eye and central cornea thickness.Result The axis length of low myopia group,medium myopia group,high myopia group and super myopia group was(24.32?1.73)mm,(25.33?1.49)mm,(26.04?1.92)mm,(27.47?2.57)mm respectively. There were obvious differences of axis lengths between four groups(P=0.000).The cornea curvature in high myopia group was obviously different from those in low myopia group and medium myopia group.There were no significant differences of cornea thickness among four groups(P=0.409).The axis lengths of eyes respectively had correlations with diopters(r=0.734,P=0.000),vertical and horizontal cornea curvatures(r=-0.312,P=0.000;r=-0.328,P=0.000).Conclusion The main effective factor on the diopter of myopia is the axis length for most patients.For the patients with high myopia,the cornea curvature is another effective factor.With the increase of axis length,the cornea curvature decreases,and the cornea turns flatter.(Ophthalmol CHN,2006,15:321-323)

Objective To analyze the biological characteristics and morphologic features between the mouse models using MDA-MB-231 cells established by injecting tumor cell suspension or implanting tumor tissues. Methods Twenty BALB/c mice were randomly divided into two groups,with 10 in each group.The orthotopic models of breast cancer were established by injection of tumor cell suspension or implantation of tumor tissues in the fat pad of right second breast in the nude mice of the two groups,respectively.The time of tumor formation,success rate,tumor growth rate,shape,central tumor necrosis,blood vessel distribution and tumor ulceration were compared between the two groups of models.The histological features of the tumors were also observed. Results There were no significant difference in the success rate between the two methods.In the group of tumor tissues implantation,the tumors formed in an earlier time with various shape configurations,and they were hypovascular and vulnerable to central necrosis with the resultant superficial ulcerations.However,in the group with injection of tumor cell suspension,the tumors formed later with a regular shape,and the superficial ulceration was rare and not vulnerable to central tumoral necrosis since the tumors were abundant in blood vessels resulting in adequate nourishment.There were no significant difference in the pathological findings between the two groups. Conclusion The nude mouse models of breast cancer can be successfully established by both tumor tissues implantation and tumor cell suspension injection,with identical biological characteristics and fairly different morphological features.The investigators are well advised to choose the more appropriate one according to the purpose of the experiments.
