Wheezing in children is a common problem.Approximately 30 percent of infants will have at least one wheezing episode.Although asthma is the condition most commonly associated with wheezing,the high prevalence of wheezing as a common presenting complaint requires consideration of a broad and age-dependent differential diseases.A high index of suspicion of cardiovascular anatomic anomalies should be maintained in infants and children with recurrent wheezing and minimal improvement despite reasonable treatment.Compression of the pediatric airway is a relatively common and often unrecognized complication of a variety of cardiovascular diseases.The most common congenital anomalies associated with airway compression are the vascular rings.Vascular ring abnormalities are aortic arches abnormalities,aberrant left pulmonary artery (pulmonary sling) or aberrant i nnominate artery (innominate artery syndrome).Aortic arches abnormalities include double aortic arch,right/left sided aortic arch with ligamentum arteriosum and aberrant left subclavian artery or cervical aortic arch.Other rare reasons could cause the compression of airway are absent pulmonary valve,aneurysm,left atrial enlargement or massive cardiomegaly.Imaging techniques are usually required for diagnosis.First-tier evaluation of the child with recurrent wheeze should include a chest radiograph.Echocardiography,multi detector computed tomography (MDCT) or magnetic resonance imaging (MRI) are performed as the diagnostic pathway.Bronchoscopy is currently the techniques to assess the degree of bronchial malacia and narrowing in pre-operation.Treatment of these abnormalities usually is surgical.

BACKGROUND: Anchorage control is a critical part of orthodontic treatment, and physiologic anchorage loss consists of molar growth and drifting.OBJECTIVE: To detail the principles of physiologic anchorage spee-wire system through the growth and biologic force aspects.METHODS: A computer retrieval of PubMed and CNKI databeses was performed for relevant articles published from June 1976 to October 2016 using the keyword of physiologic anchorage control;anchorage loss; mandible growth in English and Chinese, respectively.RESULTS AND CONCLUSION: The physiologic anchorage spee-wire system cannot only avoid natural growth-induced physiological anchorage loss but also preserve molar anchorage,so as to achieve the request of maximum anchorage.

Methods:One hundred and sixty patients were randomly divided into two groups. 80 cases in the control group was treated by conventional acupuncture by filiform needles and 80 cases in the treatment group were treated by electroacupuncture. The therapeutic effects were evaluated after two courses of treatment.Results:After two courses of treatment,the therapeutic effect for edema on back of the hand and hand pain in digital flexion and the total effective rate were better in the treatment group than in the control group (P＜0.05). Conclusion:Electroacupuncture is of significant importance for relieving pain on back of hand,preventing the muscular atrophy of hand and promoting recovery from apoplexy.

Objective To investigate the effects of different degrees of white mustard stir-processing on patient skin after acupoint application. Methods The same production batch of raw white mustard were randomly allocated to groups A, B and C. Fifty asthma patients were received acupiont application. Raw white mustard was stir-processed into slight yellow in group A, deep yellow in group B and coke yellow in group C. the skin reaction was observed in the three groups of patients after acupoint application. Results Obvious skin burning heat and burning pain sensations, and skin redness accompanied by many blisters occurred at the place of application in group A. Skin warming sensation, no or a small amount of needle tip-like blisters and skin redness without edema occurred at the place of application in group B. No or slight skin redness and unobvious skin warming sensation occurred at the place of application in group C. Conclusion White mustard stir-processed into deep yellow can effectively reduce the excessive stimulation of medicine to the skin and not markedly affect the amount of medicamentous stimulation to the acupoint.

Objective To discuss the influence of high-quality rehabilitation model intervention on postoperative anxiety,depression and quality of life in patients with colorectal cancer.Methods 60 patients with colorectal cancer in our hospital were randomly divided into the observation group and the control group,30 cases in each group.The control group was given routine nursing measures.The observation group received high-quality rehabilitation model intervention on the basis of routine nursing measures.SAS and SDS were used to observe the psychological status of the patients,SF-36 was used to observe the quality of life of patients.Results Two weeks after operation,SAS,SDS scores of the observation group were (47.5 ± 5.2) points,(49.7 ± 5.7) points,which were significantly lower than (55.2 ± 6.3) points,(53.4 ± 5.8) points of the control group (t =5.163,2.492,all P ＜ 0.01).Two weeks after operation,the general health,physiological function,physical function,body pain,activity,social function,emotional function,mental health,quality of life score in the observation group were (79.06 ± 3.78)points,(79.57 ±3.96)points,(78.39 ± 3.71) points,(76.98 ± 3.52) points,(77.59 ± 4.16) points,(75.52 ± 4.85) points,(79.28 ±4.91) points,(78.31 ± 4.27) points,which were significantly higher than those of the control group (74.19 ±4.07)points,(75.24 ± 4.12) points,(71.92 ± 4.38) points,(73.25 ± 3.47) points,(74.06 ±4.13)points,(72.17 ±4.21) points,(74.65 ± 4.35) points,(73.87 ± 3.92) points(t =4.802,4.150,6.174,4.133,3.298,2.857,3.866,all P ＜ 0.01).Conclusion High-quality rehabilitation model can significantly improve the postoperative anxiety and depression,and improve the quality of life of patients with colorectal cancer.

Objective: To explore health resource allocation and optimization and evaluate the clinical departments efficiency in hospital. Methods: Taking a three level of first-class hospital in Beijing for example, the method of data envelopment analysis (DEA) was used for building a DEA model of clinical departments efficiency in hospital. Results: Based on the results of the DEA model, we drawn the technical efficiency and scale efficiency of the target clinical departments, obtained input redundancy rates and output deficiency rates of the non-effective decision-making units. Conclusion:By DEA evaluation results, the input redundancy and output deficiency of the target clinical departments are found. From the perspective of optimizing hospital resource allocation, measures to improve the hospital operational performance are proposed. There is important significance to improve the comprehensive competitiveness of the hospital.

anthracycline-induced cardiotoxicity in patients with lymphoma.Methods Thirty-two adult patients with nonHodgkin' s lymphoma who received chemotherapy including anthracyclin were studied.After anthracyclin reached the cumulative doses of 200 and 400 mg/m-2,the changes in plasma BNP and echocardiography indices were investigated.Results After the cumulative anthracyclin reached doses of 200 and 400 mg/m2,serum BNP were respectively (292±7) ng/ml and (387±4) ng/ml,and were significantly increased when compared to the untreated (134±6) ng/ml (P ＜ 0.05).The parameter of diastolic functions ratio of peak early to peak late low velocity (E/A ratio)were 1.14±0.37 and 0.90±0.06,both showing significant decreases compared to the control (1.33±0.27) (P ＜ 0.05).In contrast,systolic function parameters left ventricular ejection fraction (EF) and fractional shortening (FS) remained unchanged (P ＞ 0.05).After the cumulative anthracyclin reached 200 and 400 mg/m2,significant negative correlations were observed between the plasma BNP and the E/A ratio (r =-0.689,P=0.042; r=-0.557,P =0.006),but no associations between EF and FS were found (P ＞ 0.05).Conclusion Plasma BNP concentration appears to be a sensitive parameter for the early assessment of anthracycline-induced cardiotoxicity.

Objective To investigate the impact of cerebral microbleeds (CMBs) on cognitive function in ischemic stroke patients.Methods A total of 268 acute ischemic stroke patients recruited in the Ningbo First Hospital from January 2014 to June 2015 were divided into CMBs group (199 patients) and non-CMBs group (69 patients) according to whether complicated with CMBs by susceptibility-weighted imaging (SWI).According to the microbleed number, CMBs group patients were divided into 2 grades: grade 1 (1-5 CMBs) and grade 2 (≥6 CMBs). Montreal Cognitive Assessment (MoCA) was used to evaluate and compare the global cognitive function and cognitive domains of the patients. Results The total MoCA score and the scores of visuospatial/executive, attention domains in CMBs group were 20.95±4.53, 2.53±1.09, 3.83±0.97, while those in non-CMBs group were 26.82±1.25, 3.16±1.24 and 4.91±0.84. The total MoCA score and the scores of visuospatial/executive, attention domains were significantly lower in CMBs group than those in non-CMBs group (t=16.59, P<0.01;t=3.75, P<0.01;t=8.83, P<0.01). The total MoCA score and the score of attention domain in grade 1 CMBs group were 21.53±4.61 and 4.11±0.91 , which were significantly lower than those in non-CMBs group (t=14.09, P<0.01;t=14.23, P<0.01). Whereas the total MoCA score and the scores of visuospatial/executive, attention, orientation domains in grade 1 CMBs group were 21.53±4.61, 2.88±1.06, 4.11±0.91, 4.96±0.40, which were significantly higher than those in grade 2 CMBs group (18.58±3.08, 2.23±0.95, 3.63±1.01, 3.85±0.39, respectively;t=2.85, P<0.01;t=2.54, P<0.05;t=5.63, P<0.01;t=2.58, P<0.01). Multivariate regression analysis showed that independent risk factors of MoCA scores in ischemic stroke patients included CMBs (OR=3.15, 95% CI 1.28-5.12, P=0.005) and the number of CMBs (OR=1.73,95% CI 1.08-2.32,P=0.031). Conclusions CMBs and the number of CMBs were independently associated with cognitive impairment in ischemic stroke patients. And with the increasing of the microbleed number, the impairments of certain cognitive domains were more obviously.
