Through the literature combing the interest groups of hospital information disclosure in the United States, the demand and practice of the main interest groups are analyzed. This paper uses policy maker4. 0 software to further analyze the interests of various interest groups, power and the degree of influence by the policy of hospital information disclosure. The results showed that interest groups involved in hospital information disclosure in the Unit-ed States can be mainly divided into five categories:consumers, employers, health insurance companies, hospitals, and decision makers ( government) . In order to balance the cost-effectiveness of various insurance schemes, health insurance companies choose high-quality service providers to restrict poor-service providers and insurers, and hospi-tals need to use public information to manage and improve health care. In order to monitor and improve the quality of medical services, employers need to weigh various insurance plans, health insurance companies have to measure the service quality of themselves and competitors, and hospitals need to manage and improve the medical quality and in-crease market share. As the largest stake in the hospital information disclosure, the results show that the consumer's position on the hospital information disclosure is low support. From the consumer as a main, although the hospital in-formation disclosure practices but the right to speak and other small powers have a limited participation. Analyzing the of the interest groups of hospital information disclosure in the United States, they all push forward the hospital infor-mation disclosure work to provide evidence to support.

Objective: To establish a rapid approach to the detection and identification of Mycobacteria from lesions of patients with suspected Mycobacterial infections. Methods: Specimens were obtained from five patients suspected to have Mycobacterial infections. DNA extracted from clinical samples was amplified by nested PCR. The PCR products were digested with Hha Ⅰ, MboⅠ, and BstUⅠ restriction enzymes and applied to PAGE. The species of Mycobacteria were determined by restriction fragment length polymorphism (RFLP) analysis. Identification of Mycobacteria culture was also performed in 3 patients. Results: M. marinum was found in two patients diagnosed as swimming pool granuloma. M. tuberculosis was found in one patient diagnosed as infectious skin granuloma. All these 3 Mycobacteria were confirmed by Mycobacteria culture. A strain of M. tuberculosis and a strain of M. fortuitum were detected in remain two patients. Conclusion: The results above indicate that PCR-RFLP analysis is rapid and reliable in detection and identification of different Mycobacteria species from skin tissues. Application of this method will be helpful for early diagnosis and treatment of Mycobacteria skin infections.

Objective To explore the efficacy and safety of different doses of budesonide mixed suspension atomization inhalation in children with post infectious cough,and provide reference for the rational use of budesonide.Methods One hundred and twenty children with post infectious cough aged 2-14 years old were selected and divided into three groups by random digits table method (40 cases in each group).Control group was treated with 4 mg once montelukast sodium chewable tablets for 2-5 years old children,or 5 mg once for 6-14 years old children.Low-dose group was treated 2 times/d with a dose of 0.5 mg budesonide mixed suspension diluted in normal saline to 4 ml based on control group and high-dose group was treated 2 times/d with a dose of 1.0 mg budesonide mixed suspension diluted in normal saline to 4 ml based on control group.The outcome of curative effects were recorded and analyzed after 7 days of treatment.Results The total efficacy rate was 70.0％(28/40),52.5％(21/40),35.0％(14/40) in high-dose group,low-dose group and control group after 3 days of treatment,and there was significant difference between high-dose group and control group (P＜ 0.01).The total efficacy rate was 92.5％(37/40),90.0％(36/40),72.5％ (29/40) in high-dose group,low-dose group and control group after 7 days of treatment,and there was no significant difference(P ＞ 0.025).Few adverse events associated with inhaled corticosteroids,such as thrush,sore throat,hoarseness were observed in three groups.Conclusions Budesonide mixed suspension atomization inhalation alleviates symptom of post infectious cough significantly with no obvious side effects,even in high-dose group which has a more outstanding efficacy.Therefore,this therapy is valuable in clinical application.

Objective To investigate the relationship of thyroid hormones and serum lipid profile during Pregnancy. Methods 30 cases of healthy pregnant women were recruited in the study. The thyrotropin (TSH), free triiodothyronine (FT3), free thyroxine (FT4) and serum lipid profile were examined at 9 ~ 12, 14 ~ 17, 23 ~ 26 and 37 ~ 40 weeks of gestation and the correlations between them were analyzed. Results Positive correlation could be found between serum TSH and total cholesterol (CHOL), triglyceride (TRIG), low density lipoprotein cholesterol (LDL-C), ApolipoproteinA-I (APOA-I), ApolipoproteinB (APOB). Negative correlations could be found between serum FT3, FT4 and total cholesterol (CHOL), triglyceride (TRIG), low density lipoprotein cholesterol (LDL-C), ApolipoproteinA-I (APOA-I), ApolipoproteinB (APOB). And no correlation was found between serum thyroid hormones and high density lipoprotein cholesterol (HDL-C). Conclusion The thyroid hormones were closely related to serum lipid profile except of HDL-C.

Objective:To study the metabolism of high density lipoprotein cholesterol ( HDL-C ) and apolipoprotein A-Ⅰ( ApoA-Ⅰ) in different thyroid function status during pregnancy. Methods:This study re-cruited thirty cases of euthyroid, with nineteen cases of subclinical hypothyroid and eight cases of subclini-cal hyperthyroid pregnancy. The concentrations of fasting serum HDL-C and ApoA-Ⅰwere detected and ana-lyzed from 9-12, 14-17, 23-26, and 37-40 gestational weeks. Friedman repeated measures ANOVA on ranks was adopted to analyze the changes of serum HDL-C and ApoA-Ⅰat different stages. General line-ar model ( GLM) was adopted to analyze the differences of serum HDL-C and ApoA-Ⅰin different thyroid function status during pregnancy. Results:There were no significant differences of maternal serum HDL-C among different stages (χ2 =5. 428,P=0. 143,χ2 =2. 027,P=0. 567,χ2 =2. 885,P=0. 410). There were significant differences of serum ApoA-Ⅰduring euthyroid and subclinical hypothyroid pregnancies (χ2 =46. 343, P<0. 001,χ2 =35. 984, P<0. 001), and no significant difference during subclinical hyperthy-roid pregnancy (χ2 =6. 750, P=0. 080). There were significant differences of serum HDL-C and ApoA-Ⅰbetween euthyroid and subclinical hyperthyroid pregnancies (P=0. 025,P=0. 027), and no significant differences between euthyroid and subclinical hypothyroid pregnancies (P=0. 378,P=0. 549). Conclu-sion:Subclinical hyperthyroidism affected the metabolism of maternal serum HDL-C and ApoA-Ⅰ, which could affect the fetal growth and development. Subclinical hypothyroidism ( after treatment with drugs) had no obvious effect on the metabolism of maternal serum HDL-C and ApoA-Ⅰ.

Congenital hypertrophic pyloric stenosis(CHPS)is a common gastrointestinal congenital mal-formation in neonate and small infants.Pyloromyotomy is an effective method for treatment of CHPS,including several methods.Traditional open pyloromyotomy for the patient's body injury is serious,such as accident of an-esthesia,postoperative infection,skin scar;laparoscopic pyloromyotomy can cause the pylorus muscle incision uncomplete,invasive operation damage,etc.Endoscopic pyloromyotomy for neonatal has some advantages:a lit-tle injury,no scars,simple operation,less complications,quicker recovery of feeding.Endoscopic mucosal pyloro-myotomy may be a new method of treatment,needing further exploration and research.

BACKGROUND:Overtraining is a series of functional disorder or pathological state induced by continuous fatigue accumulation because exercise load and body function are incommensurate to each other. At present, commonly used methods for establishing rat models of overtraining included treadmil , swimming and climbing rod, but treadmil is comparatively accepted in the world.
OBJECTIVE:To establish the standard of overtraining rat model and to implement objective of model establishment by dynamical y monitoring biochemical indexes and observing behavioral changes.
METHODS:A total of 16 Sprague-Dawley rats were randomly assigned to model and blank control groups. The model group received movement training according to the plan. After adaptable feeding, training was performed, 6 days every week, with a rest of 1 day. Increasing intensity on treadmil was used. From the first week of training, the speed, gradient and running time were gradual y increased. However, the blank control group was conventional y fed, without any training.
RESULTS AND CONCLUSION:Behavior changes of the training rats were arisen after five weeks. Serum creatine kinase levels increased continuously in training process, and higher than basic levels at 5 weeks (P<0.01). Serum urea nitrogen levels persistently increased, and higher than basic levels at 3 weeks (P<0.05). Hemoglobin and serum testosterone levels increased and then decreased, and significantly lower than basic levels at 8 weeks (P<0.05). Behavioral y, overtraining appeared. Simultaneously, hemoglobin and serum testosterone levels were significantly lower than basic levels. Serum creatine kinase and serum urea nitrogen levels were significantly higher than basic levels. These results indicated that the body was in overtraining state. The standard of overtraining rat model was established in this study. The overtraining rat model was established according to the training program when the training was lasted for 8 weeks, the training speed was 30 m/min;every training time was 110 minutes, and the gradient was 15°.

Objective To study the effect of transmembrane tumor necrosis factor-alpha (TM-TNF-αt) on human cervical carcinoma HeLa cells,and explore the correlations with silencer of death domain (SODD).Methods The expression of proliferating cell nuclear antigen (PCNA) was detected by immunocytochemistry.The expression of SODD in human cervical carcinoma HeLa cells undisposed and after disposed with TM-TNF-α was detected by reverse transcription-polymerase chain reaction,and the influence of TM-TNF-α on human cervical carcinoma HeLa cells was analyzed.Results The positive rate of PCNA in undisposed human cervical carcinoma HeLa cells was 80.3％ (155/193),in human cervical carcinoma HeLa cells disposed with TM-TNF-α was 46.7％ (85/182),there was statistical difference (P ＜ 0.05).The cycle index of polymerase chain reaction in human cervical carcinoma HeLa cells was 28 times,the amplification product was disposed by 2％ agarose gel electrophoresis,the gray scale disposed by TM-TNF-α and undisposed human cervical carcinoma HeLa cells were 1.377 ± 0.170 and 0.815 ± 0.040,there was statistical difference (P ＜ 0.05).Conclusion TM-TNF-α has obvious cytotoxic effect on human cervical carcinoma HeLa cells in vitro which may due to its up-regulating the expression of SODD.
