Objective To assess hearing and efferent system functions of autistic children.Methods Tests were performed on 30 Autistic children and 15 normal children to evaluate hearing objectively by using otoacoustic emission (OAE) and auditory brainstem response (ABR).The efferent system functions were analyzed through contralateral suppression in OAE.Results The mean ABR Ⅰ-Ⅴ interpeak latencies (IPLs) in children with Autism were significantly reduced than that in the control group.The amplitudes of OAE at 1 kHz and 2 kHz in autistic children were significantly different in two groups.There were no significant differences in contralateral suppressions between the Autistic children and the control.Conclusion Hearing impairment may be more common in children with Autism than in normal children,while for a few Autistic children,their efferent system functions are affected.

Objective To investigate the association between β2-adrenergic receptor gene polymorphism and coronary atherosclerotic heart disease, and to provide reference for clinical disease prevention and treatment.MethodsThe clinical data of 200 patients with coronary atherosclerotic heart disease confirmed by coronary angiography were selected and included in the study group, and 200 healthy subjects without coronary atherosclerotic heart disease group.The polymorphism of β2 adrenergic receptor gene was detected and the frequency of each gene was analyzed.ResultsThe genotype frequencies of β2-adrenergic receptor gene were in accordance with Hardy-Weinberg equilibrium, the difference was not statistically significant.According to dominant genetic model, the frequency of AA+AG was 46.0% vs 58.0% lower than that of the control group, and had statistical significance, The genotype frequency of GG genotype in study group was significantly lower than that in control group 14.0% vs 26.0%, χ2=26.20, P=0.00.The frequency of GG genotype in study group was significantly higher than that in control group 54.0% vs 42.0%, χ2=5.76, P=0.01.The frequency of A gene was 38.0% compared with 44.0% in control group, χ2=1.48, P=0.22;the frequency of AA gene in study group was 30.0%, and the frequency of gene A was 38.0%, compared with 56.0% Compared with 32.0% in the control group, χ2=0.18, P=0.66.ConclusionThe A/G polymorphism of β2-adrenergic receptor gene is closely related to the clinical pathogenesis of coronary atherosclerotic heart disease, and the A allele may be a protective factor in patients with coronary atherosclerotic heart disease.

Objective　To study the relationship between apoE alleles and life-span. Methods　Apolipoprotein E genotypes were determined in 164 unrelated Uygurs including 35 persons aged 90 years or older, 71 men aged 20-35 and 54 men with myocardial infarction by using polymerase chain reaction-restriction fragment length polymorphism. Apolipoprotein E gene polymorphism was analyzed among three groups. Results　There was statistically significant difference in the ε4 allele frequencies among three groups. The ε4 allele frequency in olds was the lowest (0.057), while in patients suffering from myocardial infarction (MI) was the highest (0.213). In MI patients the average age of first attack in ε4 allele carriers was significantly younger than that of non-carries, 51.3 and 58.3 years, respectively (P<0.05). Conclusion　ApoE genotype may have some impact on human longevity.

OBJECTIVE: To compare the therapeutic effects of low-temperature plasm radiofrequency and high-intensity focused ultrasound in treatment of perennial allergic rhinitis (PAR) complicated with nasal septum deviation. METHOD: A total of 224 cases of identified PAR who treated in our hospital were randomly divided into 2 matched groups: low-temperature plasm radiofrequency group (n = 140) and high-intensity focused ultrasound group (n = 84). The therapeutic affection were evaluated by clinical symptoms controlled counting-scores. Inferior turbinate mucosa were collected and examined pathologically before and at 15 days and 6 months after the therapy. RESULT: The follow-up data indicated the effective rate in 15 days was 97.1% in high-intensity focused ultrasound group, and 90.4% in low-temperature plasm radiofrequency group, in 6 months was 90.7% and 85.4% respectively. CONCLUSION The treatment of high-intensity focused ultrasound in PAR is minimally invasive and safe with reliable efficacy.

Objective:To investigate the clinical application value of triamcinolone acetonide combined with hyaluronidase injection and shallow X-ray in the treatment of multiple keloids.Methods:From March 2018 to October 2019, 144 cases of multiple keloids in outpatient department were analyzed retrospectively. There were 89 males and 55 females, aged from 16 to 68, with an average age of 28 years. The average duration was 6 years(ranged from 1 to 20 years). Among them, 65 cases were treated with superficial X-ray radiotherapy combined with local injection (group A) and 79 cases were treated only with local injection (group B). The Vancouver Scar Scale (VSS), t-test and chi-square test were used to evaluate the validity of the two groups. The patients were followed up for 6-18 months. Results:In group A, the VSS was changed from 11.9±0.9 to 6.5±1.1. 51 cases were improved and 14 cases showed obviously effective. The significant effect rate was 21.54%(14/65). The main side effect of group A was transient pigmentation. In group B, the VSS was changed varied from 12.1±1.0 to 8.3±1.0. 74 cases were improved, 2 cases were markedly effective, but 3 cases were ineffective. The significant effective rate was 2.63%(2/76). The side effects include telangiectasia, skin atrophy, even arousing abnormal menstrual cycles and hair growth in several females. The comparability between the two groups was confirmed by the VSS scores before treatment( t=-1.114, P=0.267). Then, the difference of VSS scores became significant after treatment( t=-10.208, P<0.001), the same to apparent efficiency( χ2=12.450, P<0.001). Conclusions:Triamcinolone acetonide combined with hyaluronidase injection and shallow X-ray radiation therapy for multiple keloids has ideal curative effect and low incidence of adverse reactions, which is a prospected clinical method.

Polymyxin B, which is a last-line antibiotic for extensively drug-resistant Gram-negative bacterial infections, became available in China in Dec. 2017. As dose adjustments are based solely on clinical experience of risk toxicity, treatment failure, and emergence of resistance, there is an urgent clinical need to perform therapeutic drug monitoring (TDM) to optimize the use of polymyxin B. It is thus necessary to standardize operating procedures to ensure the accuracy of TDM and provide evidence for their rational use. We report a consensus on TDM guidelines for polymyxin B, as endorsed by the Infection and Chemotherapy Committee of the Shanghai Medical Association and the Therapeutic Drug Monitoring Committee of the Chinese Pharmacological Society. The consensus panel was composed of clinicians, pharmacists, and microbiologists from different provinces in China and Australia who made recommendations regarding target concentrations, sample collection, reporting, and explanation of TDM results. The guidelines provide the first-ever consensus on conducting TDM of polymyxin B, and are intended to guide optimal clinical use.
