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.

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.

Transcutaneous immunization (TCI) is a novel immunotherapy approach that induces systemic immune responses via topical application of antigens and adjuvants onto the skin.It is a safe and effective method,and is expected to serve as an attractive alternative to traditional vaccination.TCI induces immune responses in different directions,but the exact mechanism of skin immune tolerance is still unclear.Most studies on TCI are based on animal models.However,there are structural differences between animal skin and human skin,so more researches are needed to achieve the translation of TCI from bench to bedside.Not all vaccines are suitable for cutaneous inoculation,so vaccines for TCI should be evaluated for their safety and efficacy.Various reformed vaccine delivery systems are needed to be further explored in related diseases.

Atopic dermatitis (AD) is an inflammatory skin disease commonly complicated by atopic diseases such as asthma and allergic rhinitis,and occurs most frequently in children.Due to severe conditions and recurrent attacks,severe AD seriously affects the quality of life in patients and their families,and systemic treatments are needed.With further studies on immunosuppressants and expansion of their indications in recent years,immunosuppressants have become an important immunotherapy of AD.However,for special populations,especially children,the efficacy and safety of immunosuppressants are still needed to be evaluated for the treatment of AD through basic researches and randomized controlled clinical trials,so as to provide more information for clinical medication as well as better guidance for clinical treatment.

Guanylyl cyclase C( GCC)is a specific intestinal tissue polypeptide expressed in intestinal epithelial cells,and is also expressed in colorectal cancer cell line and primary and metastatic colorectal cancer. Studies have indicated that level of GCC mRNA in blood could contribute to the early detection of colorectal cancer metastasis and recurrence,and is beneficial to the formulation of therapeutic regimen and follow-up. This article reviewed the progress in research on GCC in diagnosis and treatment of colorectal cancer.

Antihistamines,a group of drugs most commonly used for the treatment of allergic diseases in dermatology,exert favorable efficacy and are well tolerated in most people.Due to their wide application,the safety of medication is particularly important.When they are used in some special populations with allergic diseases,such as children,pregnant and lactating women,the elderly and people with hepatic or renal insufficiency,their pharmacodynamics,metabolic characteristics and interactions with other drugs should be fully considered,and profits of medication and potential adverse effects should be well weighed before choosing relatively safe antihistamines.In addition,decreasing the routine dose or prolonging intervals between the administration of antihistamines may also be attempted to achieve maximum safety.

To compare the clinical efficacy and safety of atomization inhalation of epinephrine combined with budes-onide and dexamethasone in the treatment of children with acute laryngitis. Methods:Totally 68 cases of children with acute laryngitis were randomly divided into two groups. The two groups were given the conventional therapy, and 30 cases in the control group were giv-en dexamethasone inhalation additionally, and the treatment group was given epinephrine combined with budesonide inhalation addition-ally. The clinical effect in 12, 24 and 72h, clinical symptom disappearance time and adverse reactions in the two groups were ob-served. Results:The clinical effect of the treatment group in 12, 24 and 72h was better than that in the control group. 72h after the treatment, 17 cases in the control group were cured, and the curative rate was 56. 67%, while 27 cases in the treatment group were cured with the curative rate of 71. 05%. The disappearance time of dyspnea and stridor, barking cough, hoarseness and the other clini-cal symptoms in the treatment group was significantly shorter than that in the control group, and the difference was statistically signifi-cant (P<0. 05). The two groups had no obvious adverse reaction. Conclusion:The clinical effect of the combination of epinephrine and budesonide inhalation in the treatment of children with acute laryngitis is better than that of dexamethasone inhalation, and the combination is safe and effective, which is worthy of clinical application.

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.
