Objective To explore the genetic mutation in neonates who failed to pass hearing screening.Methods A total of 111 cases of neonates who failed to pass hearing screening and were conifrmed sensorineural deafness by auditory brainstem evoked potential (ABR) were randomly selected. The heel blood was collected and DNA was extracted.GJB2, SLC26A4, and 11 mutation hotspots in mitochondria gene12SrRNA were tested. The relationship between degree of hearing loss and gene mutation was analyzed.Results In 111 neonates, mutation in deafness gene were found in 24 cases (21.6%) . Among them 14 cases (12.6%) hadGJB2 gene mutation including 5 cases of 235delC single heterozygous mutation, 5 cases of 235delC, and 1 case each of 299_300delAT compound heterozygous mutation, 235delC homozygous mutation, 299_300delAT single heterozygous mutation, 176_191del16 and 235delC compound heterozygous mutation, and 299_300delAT and 508_511dupAACG compound heterozygous mutation respectively. Ten cases (9.0%) hadSLC26A4 gene mutation including 2 cases of IVS7-2A>G single heterozygous mutation, 3 cases of 1226G>A single heterozygous mutation, 2 cases of 2168A>G single heterozygous mutation, and 3 cases of IVS7-2A>G and 2168A>G compound heterozygous mutation. Mitochondrial gene mutations were not detected. Conclusions Deafness gene mutation is detected in more than 1/5 neonates who failed to pass newborn hearing screening. GJB2 gene mutation is the most commons. The implementation of hotspots deafness gene detection can improve the diagnostic rate of deafness.

Objective To improve the diagnosis and treatment of eosinophilic lung disease.Methods Patients who were diagnosed with eosinophilic lung disease and hospitalized in the First Affiliated Hospital of Guangxi Medical University Hospital were retrospectively analyzed from January 2004 to August 2012.Data of etiology,clinical manifestation,imaging and pathological features,diagnosis and treatment were recorded.Results A total of 25 patients were diagnosed with eosinophilic lung disease including 9 chronic eosinophilic pneumonia,6 churg-strauss syndrome,and 10 cases of parasitic infection of which two patients were the simple pulmonary eosinophilia (L(o)ffler syndrome).Eosinophil counts in peripheral blood and bronchoalveolar lavage fluid (BALF) were increased.Arterial gas analysis showed varying degree of hypoxemia,which pulmonary function tests showed restrictive,obstructive,mixed ventilatory dysfunction.Chest CT showed bilateral flaky,streak or flake diffuse ground-glass infiltrates and reticular opacities.Results of pulmonary biopsy or skin biopsy identified diffuse eosinophil infiltration.Corticoidsteroid therapy alone or combined with immunosuppressive agents were both effective.Conclusion (1) Liver fluke and other food-borne parasites are the most common causes in eosinophilic lung disease; followed by unexplained chronic acidophilic granulocyte pneumonia; (2) In addition to histopathological evidence,the diagnosis of eosinophilic lung disease was made comprehensively based on clinical features,laboratory test,the BALF analysis,and imaging data.

Nitrous oxide/oxygen is one of the inhaled anesthetics that receives attention by scholars at home and abroad for its unique characteristics of excellence comparing with intravenous sedation analgesia which is more commonly used. In addition, the nurses who are the main body personnels of the pain management have certain differences in the implementation of the nitrous oxide/oxygen sedation analgesia both at home and abroad. In this paper, the nitrous oxide/oxygen analgesia and sedation and its nursing implications were reviewed from the physical and chemical properties, pharmacokinetic characteristics, excellent properties, mechanism of action and clinical application, then development directions of management in the future are put forwarded so as to provide theoretical evidences and practical guidelines for domestic medical staffs cooperating to implement the technology.

OBJECTIVETo study the clinical effect of combination of kurarinone (KR) and interferon a-lb (IFNalpha-1b) in treating chronic hepatitis B.

METHODSOne hundred and forty-six patients with chronic hepatitis B were randomized into four groups. Under the basic conventional treatment, additional KR combined IFNa-lb was given to Group A, IFNa-lb to Group B and KR to Group C while none was given to Group D. The therapeutic course for them was 6 months and succeeded with 6 months of follow-up. Changes in liver histology, expression of transforming growth factor beta (TGF-beta) in liver tissue, and serum levels of TGF-beta, hyaluronic acid (HA), laminin (LN), collagen type IV (IVC), precollagen III (PCIII), as well as the negative conversion rate of HBeAg and HBV DNA, and normalization rate of alanine transaminase (ALT) before and after treatment were observed by immuno chemical method, RIA and ELISA.

RESULTSAfter treatment, in Group A, the scores of liver fibrosis and all the above-mentioned indexes significantly lowered, as compared with those in Group B and C, the difference was significant (P<0.05 or P<0.01). The negative conversion rate of TGF-beta in liver tissue was in accordance with the dynamic change of liver fibrosis. Comparison between Group B and C in those aspects showed insignificant difference (P >0.05).

CONCLUSIONKR combined with IFNalpha-1b shows better effect in treating chronic hepatitis B than that of using either of the two alone.

Objective To investigate the predictive value of early prognosis of the 40 Hz auditory steady-state response (40 Hz ASSR) in patients with coma following cardiopulmonary resuscitation (CPR). Methods Thirty patients with coma following CPR admitted in the Neurological Intensive Care Unit (NICU) were examined with the 40 Hz ASSR and shortlatency somatosensory evoked potential (SLSEP), and both were graded. Using transferred out of NICU as the short-term outcome end point, the patients with coma following CPR were divided into a survival group (n =21) and a death group (n =9; including brain death). The correlation between the 40 Hz ASSR and SLSEP grading and prognosis was analyzed. Results The grades of the 40 Hz ASSR (r = 0. 722, P = 0.000) or SLSEP (r = 0. 430, P = 0.018) was significantly correlated with the short-term prognosis. The sensitivity, specificity and accuracy of the 40 Hz ASSR for predicting the short-term prognosis were 77. 8%, 100% and 93.3%, respectively; and those of SLSEP were 88. 9%, 61. 9% and 70. 0%, respectively. Conclusions The 40 Hz ASSR has a certain prognostic value in patients with coma following CPR. The higher the grade of the 40 Hz ASSR is, the greater the likelihood of the recent death.
