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.

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.

OBJECTIVETo evaluate the clinical efficacy of warming-needle moxibustion on cervical headache.

METHODSSixty-one patients of cervical headache were randomly divided into a warming-needle moxibustion group (30 cases) and an acupuncture group (31 cases). Tianzhu (BL 10), Fengchi (GB 20), Wangu (GB 12), Tianyou (TE 16), Hegu (LI 4), Taichong (LR 3) and Zulinqi (GB 41) were selected in the two groups. Patients in the acupuncture group were treated with acupuncture; patients in the warming-needle moxibustion group were treated with warming-needle moxibustion at Tianzhu (BL 10), Fengchi (GB 20) and Wangu (GB 12) and acupuncture at the remaining acupoints. The treatment was given once every other day, 3 times a week, and totally 4-week treatment was given. The duration and frequency of headache, numerical rating scale (NRS) of headache and cervical range of motion (ROM) were compared before and after treatment in the two groups; also the efficacy of the two groups was evaluated.

RESULTSAfter treatment, the duration and frequency of headache, headache NRS.and cervical ROM score were improved in both groups (all P < 0.05), which were more significant in the warming-needle moxibustion group (all P < 0.05). The total effective rate was 84.3% (25/30) in the warming-needle moxibustion group, which was significantly superior to 61.3% (19/31) in the acupuncture group (P < 0.05).

CONCLUSIONThe warming-needle moxibustion presents significant efficacy on cervical headache, which can obviously improve headache symptoms and cervical ROM.

AIM: To investigate the effect of sodium nitrite (SN) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) and its underlying mechanism in mice. METHODS: All male Institute of Cancer Research (ICR) mice were randomly divided into five groups: Control group;LPS group;and SN 4.8 nmol/L, SN 48 nmol/L, SN 480 nmol/L (ip) groups. Lung wet weight/dry weight (W/D) ratio and permeability were detected. Neutrophil infiltration in bronchoalveolar lavage fluid (BALF) was measured by cel1 counting and morphological changes in lung tissues were assayed by hematoxylin-eosin staining. The 1evels of interleukin-10 (IL-10) and tumor necrosis factor-α (TNF-α) in lung were detected. Nitric oxide (NO) level and nitric oxide synthase (NOS) activity in lung were measured according to the specification. RESULTS: Compared to lung in LPS-induced ALI mice, at doses of 4.8 nmol/L and 48 nmol/L, not 480 nmol/L, SN markedly decreased the lung W/D ratio, total leukocyte number and neutrophil percentage in the BALF, lung permeability, and TNF-α/IL-10 ratio, in lung. SN at dose of 480 nmol/L markedly increased the lung NO level compared to control group. In addition, SN decreased the total NOS and inducible NOS (iNOS) activities compared to LPS-induced ALI mice. CONCLUSION: These results indicate that the protective effect of SN against LPS-induced ALI in mice is associated with the low dose SN-induced NO, as well as the subsequent decrease in iNOS activity and TNF-α/IL-10 ratio.

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.

Retinal neuronal cells are crucial in the formation of vision.Injury or death of these cells may lead to irreversible damage to visual function due to their low regenerative capacity.The P2X7 receptor is a trimeric adenosine triphosphate (ATP)-gated cation channel.Recent studies have shown that P2X7 receptor plays a role in retinal neuronal death.In a series of animal models,when exposed to conditions of hypoxia or ischemia,elevated ocular pressure,trauma and exogenous agonists,P2X7 receptor activated by extracellular ATP can cause death of retinal neuronal cells such as retinal ganglion cells and photoreceptor cells through direct or indirect pathways.Blocking the expression and function of P2X7 receptor by its specific antagonist and gene knocking-out,the loss of retinal neuronal cells is significantly attenuated.P2X7 receptor may become a potential novel neuroprotective target for diseases related to the loss of retinal neurons.
