Objective To study the correlation between economic status and quality of life among patients with chronic ob -structive pulmonary diseases ( COPD) in Xinzhou region of Shanxi province .Methods One hundred forty -eight COPD patients in rural and urban area were randomly selected for the survey , and they filled out a questionnaire and we also accessed to medical records . The survey contains included economic burden on patients , medical expenses and mortality et al .Further to analyze the correlation be-tween economic status and quality of life in patients with COPD .Results For patients with COPD , economic burden in rural area was severe than those in urban area in economically backward areas in Xinzhou region ( P <0.05 ) , the investment on treatment in rural area was lower than in urban area ( P <0.05 ) , the quality of life in rural area was poorer than in urban area ( P <0.05 ) .Conclu-sions Backward economic situation severely restricts the treatment and quality of life in patients with COPD , and it increases the fi-nancial burden on the patient's family.It is necessary to increase the government investment , strengthen social management , and to carry out the supporting work for the patients with COPD in economically backward areas .

Objective To analyze half amount triptorelin in patients with endometriosis after application . Methods According to digifal table ,86 patients with endometriosis were randomly divided into the two groups:the observation group(43 cases)and the control group(43 cases).All patients were treated with laparoscopy .The patients in the observation group were treated through half amount triptorelin ,while the control group was treated through whole amount triptorelin .They were treated for six months .Serum carbohydrate antigen 125 ( CA125 ) and tumor necrosis factor-α( TNF-α) were measured before and after treatment .Results The groups of patients were successfully operated.The total effective rates in the control group were 97.7%in the control group and 95.3%in the observation group,there was no significant difference (χ2 =1.46,P>0.05).1-year follow-up after surgery,the control group had 5 cases of recurrence ,the recurrence rate was 11.6%,the observation group had 4 cases of recurrence ,the recurrence rate was 9.3%,there was no significant difference (χ2 =0.92,P>0.05).After treatment,serum CA125 and TNF-αwere significantly lowered,but levels of serum CA125 and TNF-αafter treatment had no significant difference (t=0.773,0.131,P>0.05).During treatment,the control group had 15 cases of adverse reactions ,the rate was 34.9%and the observation group had 5 cases of adverse reactions,the rate was 11.6%.The observation group should be significantly less than the control group (χ2 =6.78,P<0.05).Conclusion Half amount triptorelin had the quite effect with whole amout and fewer adverse reactions .

Vitamin A deficiency is a risk factor for asthma.Vitamin A plays important roles in maintaining airway epithelium phenotype,suppressing airway hyperresponsiveness,inducing immune tolerance and regulating airway inflammation,etc.The value of Vitamin A in asthma prevention and treatment has received wild attention but is still controverial.Vitamin A receptors are wildly expressed and the mechanisms are complex,more studies are needed to further clarify the relationship between Vitamin A and asthma.Besides,asthma is a polygenetic disease caused by environmental and genetic factors,and the current clinical studies of Vitamin A for prevention and treatment of asthma are not consistent.New epidemiologic studies about Vitamin A and asthma should take environmental and genetic factors into consideration.This article gives an overview about the research progress of the relationship between Vitamin A and asthma.

Procalcitonin (PCT)is a biomarker of early bacterial infection,and it can reflect severity of infection,and regarded as a prognostic factor.Community acquired pneumonia(CAP) is the main mortality and morbidity cause of children under 5 years old.The diagnosis of CAP mainly depends on clinical symptoms and chest radioactivity and regular blood test,and absent of specific indications,and mainly depends on clinicians experiences.The diagnosis and prognosis values in children CAP have been proved by many clinical trials.This paper reviews the clinical value of PCT on children CAP.

Objective To approach the clinical manifestations of childhood cough variant asthma, and summarize the dingnosis and treatment experience. Methods Retroepective analyzed the clinical data of 49 children with cough variant asthma. Results In 49 children patients,male 27 cases,female 22 cases;Age:1 ～3 years old( 11 cases) ,4 ～6 years old(25 cases) ,7 ～ 12 years old( 13 cases) ;Duration:1 ～24 months;Incidence season:wintry spring (31 cases) ,summer(7 cases) ,autumn(11 cases). Diagnoeis:CAV was 8 cases,and 24 cases were misdiagnoeed as bronchitis, 11 cases were misdiagnosed as upper respiratory tract infection,3 cases were misdiagnosed as chronic pharyngitis,2 cases were misdiagnosed as sinusitis,1 case was misdiagnosed as bronchial foreign body. In 49 children patients,32 cases were significantly effective, 15 cases effective and 2 cases noneffective. Conclusion The clinical manifestations of CAV was noepecific,and miscdiagnosis rate was high. Effect of treatment with expansion bronchical and anti-infection methods was good.

Melatonin has neuroprotective effect on hypoxic-ischemic brain damage(HIBD), which easily crosses the blood-brain barrier and plays neuroprotective role in reducing oxidative damage. Melatonin may be effective in preventing learing diabilities. It has been suggested that melatonin soporific effect is secondary to its ability to induce hypothermia. Neuroprotective effect of hypothmia has been proved. Howere, it is clear that hypothemia will not provide complete protection of HIBD and melatonin might augment protection of hypothemia in HIBD.

The innate immune system is critical to protect against microorganisms,but it is immature.Preterm newborn have to stay longer in NICU.They are vulnerable to infections.The common pathogen is coagulase-negative staphylococci which is the most cause of mortality for preterm newborn.So it is the key to understand the interaction between innate immune system of preterm newborn and pathogen.

Precocious puberty in children begins with the increased pulsatile secretion of the gonadotrophin-releasing hormone(GnRH)from hypothalamic.Recently,KISS1-GPR54 Was found to be a key factor to regulate the secretion of GnRH and the onset of puberty.Kisspeptin interacts with its receptor GPR54.which expressed on the hypothalamic GnRH neurons.and affects GnRH pulsatile release and the onset of puberty.GPR54 gene mutation causes the incidence of GnRH-dependent precocious puberty.

In recent years, ultrasonographic ultrasonographic ultrasonographic resolution level of gastrointestinal anatomy has been improved significantly due to perfection of ultrasonic instrument and development of ultrasound diagnostic technology. Currently, ultrasonographic ultrasonographic ultrasonography plays an effective role of evaluation of children's gastrointestinal obstruction diseases, especially congenital hypertrophic pyloric stenosis, gastroesophageal reflux, malrotation, midgut volvulus, superior mesenteric artery syndrome,duplication, intussusception, meconium peritonitis, meconium ileus, and congenital giant colon. The clinical manifestation and the ultrasonographic feature of all these diseases mentioned above are reviewed in this paper.

Objective To study the effect of evidence-based nursing care on medication compliance and rehabilitation effect of elderly patients with angina pectoris. Methods 89 cases of elderly people with angina pectoris were divided into the control group(43 cases )and the observation group(46 cases).The control group was treated with cardiology common nursing, the observation group received evidence-based nursing care of psychological nursing, life nursing and medication compliance. The medication compliance in each period of a year and rehabilitation effect after one year were analyzed and compared between the two groups. Results The medication compliance rate of the observation group was higher than the control group after 1, 2, 4weeks, 3, 6 months and 1 year, the total effective rate of rehabilitation was 91.3% in the observation group, also higher than the control group (62.8%)after 1 year. Conclusions Evidence-based nursing care can improve the medication compliance and the effect of rehabilitation of elderly patients with angina psctoris.
