BACKGROUND:The androgen response to resistance exercise is one of hot topics in sports science research. At present, the androgen responses to resistance exercise show different results. There are different androgen changing trends under different resistance exercise interventions.
OBJECTIVE:To have a deep insight into the influence of resistance exercise on the response of human body androgen, clarify research progress in androgen response to resistance exercise, and provide the basic theory for monitoring resistance training.
METHODS:Literatures and paper reports about androgen response to resistance exercise are electronical y retrieved from the American Biological Medical Literature Database PubMed from 1986 and 2013. Final y 46 literatures addressing the research progress is analyzed about androgen responses to resistance exercise were included.
RESULTS AND CONCLUSION:Studies have shown that, weight lifting (power snatch and power clean), squating, and deadlifting produced higher testosterone levels than the smal muscle groups. Under the same load, eccentric and concentric contractions produced the same hormone response. Adequate training amount and intensity may change the circulating testosterone levels. Short sports intermittent time led to a higher testosterone response than the long intermittent time. The free testosterone levels in youth group were significantly increased compared with the older group before and after exercise. Nutrition intervention affected acute testosterone responses to resistance exercise. Changes in exercise intensity and amount wil alter quiet testosterone levels, once returned to normal training, testosterone levels wil return to baseline values. Resistance exercise can increase androgen receptor content in human skeletal muscles.

BACKGROUND: Effect of exercise training on ultrastructure of skeletal muscle is a focus of quantified cytobiology in sports medicine. OBJECTIVE: To explore the changes of transportation function of calcium ion in sarcoplasmic reticulum of muscle in the model of reduced training after endurance training. DESIGN, TIME AND SETTING: The randomized animal trial was performed at Xi'an Sports Institute from April to July 2006, and the biochemical test was performed at the Animal Experimental Center of Xi'an Jiaotong University in July 2006. MATERIALS: Thirty-nine healthy 2-month-old male SD weighing (220?20) g were selected. METHODS: Five rats were used in the preliminary experiment, and the others were randomly divided to normal control group (n=8), endurance training group (n=8) and reduced training group (n=18). The increasing training period of endurance training group and reduced training group lasted for 6 weeks, and then reduced training group was randomly divided to 3 groups according to reduced training cycle: 2, 4 and 6 weeks group. The rats did increasing endurance loading exercise on a treadmill, while reduced intensity was used in reduced training group. MAIN OUTCOME MEASURES: Enzyme coupling method and fluorescence probe technology were used to detect sarcoplasmic reticulum Ca2+-ATPase (adenosine triphosphatase) and maximum Ca2+ uptake and release of gastrocnemius muscle. RESULTS: The activity of Ca2+-ATPase in endurance training group was significantly increased compared with normal control group (P 0.05); reduced training 4 and 6 weeks groups were significantly reduced compared with endurance training group (P 0.05); while the maximum uptake and release of Ca2+ in sarcoplasmic reticulum of reduced training 4 and 6 weeks group was significantly reduced (P

Chronic obstructive pulmonary disease(COPD) is a common condition among the old,which remains a main cause of death due to its high fatality.Airway remodeling is one of its pathological features.This article reviews the pathological changes and imageological assessment of COPD airway remodeling,its correlation with microbes and its pathogenesis and therapies.

AlM: To investigate the risk factors of diabetic retinopathy ( DR) in type 2 diabetes patients.METHODS:A total of 380 cases of type 2 diabetes were selected from January 2014 to June 2014, divided into DR group (126 cases) and non-diabetic retinopathy ( NDR) as control group (254 cases), all patients were underwent medical history, physical examinations, laboratory and assistance examinations. The prevalence and single factor and multiple factors of DR were analysed by the logistic regression model.RESULTS: The univariate logistic regression analysis showed that DR was associated with diabetes duration, systolic blood pressure, triglyceride, total cholesterol, low - density lipoprotein, urine protein, intraocular pressure, carotid intima - media thickness, peripheral neuropathy disease was the related risk factors for DR. ln multiple logistic regression analysis, only duration was the related risk factors for DR.CONCLUSlON:The occurrence of DR is the outcome of combined action of multiple factors, duration is an independent risk factor for occurrence of DR.

Objective To explore the role of IL-3,IL-5 and IL-8 in the genesis and development of nasal polypus(NP) by testing IL-3 ,IL-5 and IL-8 Value in Nasal polypus issue. Methods 50 cases of nasal polyps and 30 casesof normal middle turbinate mucosa were involved in this study. Concentrations of IL-3, IL-5 and IL-8 were determined by enzyme linked immunosorbent assay(ELISA). Results The levels of IL-3 ,IL-5 and IL-8 in Nasal polypus issue were significantly higher than that in control group( P ＜ 0.05 ). Conclusion The levels of IL-3, IL-5 and IL-8 in Nasal polypus issue rised,They likely played a certain role in the genesis and development of NP.

The incidence of thyroid cancer has increased sharply year by year. Thyroid cancer ranked from the 14th in 2003 to the 4th in 2012 most common cancers in female in Beijing. Surgery is still main solution for thyroid cancer, there are two operative procedure for thyroid cancer: total thyroidectomy, lateral lobectomy and isthmus resection. The surgeon must pay attention to intraoperative recurrent laryngeal nerve and parathyroid injury, with particular emphasis on the prevention of total thyroidectomy complications. Precise dissection of thyroid capsule, intraoperative recurrent laryngeal nerve monitoring and application of lymphatic mapping to recognize and protect negative stained parathyroid by using carbon nanoparticles tracer is prone to reduce the incidence of recurrent laryngeal nerve and parathyroid injury in the total thyroidectomy.

Objective To discuss the discovery of the neurbehavioral examination to premature infants in early abnormal neurobehavior and evaluate the influence of the hospital and family intervention pattern on the growth and development of the premature infants,so as to provide reference to the abnormal test of the premature infants and discuss the feasibility of developing neurobehavioral examination widely.Methods 152 cases of the intervention group were given neurobehavioral measurement after correction age,when the score ＜37 points,intervention and treatment were suggested in regular hospital (including exercise therapy and physical therapy,electrical nerve stmulation with treatment instrument,etc.).When the score ≥ 37points,personalized training plans were provided at home,which was adjusted in the follow-up.138 cases of the control group were given development assessment and neurobehavioral examination 3 months after correcting of age.Results The abnormal detection rate of the nervous system in the control group was higher than that of the intervention group,the scores of development in the control group were lower than that of the intervention group.Conclusions NBNA check is simple,safe and strong,it can reduce the occurrence of abnormal nervous system,and improve the level of intellectual and motor development.

Hepatic echinococcosis(HE)is a zoonosis seriously affecting the population in west China.Computed tomography(CT),magnetic resonance angiography,ultrasound angiography can be used for detection of HE with the advantages of multiple angles and high definition.CT perfusion imaging,magnetic resonance perfusion imaging,diffusion weighted imaging and magnetic resonance spectrum may provide molecular imaging to visualize HE in vitro.Total cystectomy is a radical method for the treatment of hepatic cystic echinococcosis (HCE),but has the drawbacks of HE recurrence and bile leakage;subradical cystectomy not only eliminate residual cavity of HAE,but also effectively avoids the risks which might be caused by total cystectomy.Radical hepatectomy is the first choice for the treatment of hepatic alveolar echinococcosis(HAE),while for patients with end-stage HCE,liver transplantation is the final choice of treatment.
