OBJECTIVE The short-term efficacy of endoscopic adenoid hypothermic plasma ablation and its effect on Eustachian tube function. METHODS 75 patients with obstructive sleep apnea hypopnea syndrome who were treated in our hospital from March 2013 to March 2015 were divided into two groups according to the different operative methods: nasal power cutting group(30 cases) and low temperature plasma ablation group(45 cases), comparison of the two groups of patients with surgery time, intraoperative blood loss and follow-up after 6 months of clinical efficacy and Eustachian tube function. RESULTS The time of resection, operation time and intraoperative blood loss were significantly better in the low-temperature plasma ablation group than that in the rhinectomy group, the difference was statistically significant(P<0.05); The incidence of complications in the low-temperature plasma ablation group was significantly higher than that in the rhinectomy group, and the difference was significant(P<0.05); there was no significant difference between the two groups in the total effective rate and the postoperative disease-specific quality of life questionnaire(OSA-18) and there was no significant difference in the quality of life between the two groups(P>0.05). CONCLUSION The clinical efficacy of low-temperature plasma ablation is close to nasal dynamic cutting, but low-temperature plasma ablation surgery in the amount of bleeding was significantly less than the nasal excision. This surgical approach is minimally invasive and safe, but its postoperative secondary infection and secondary bleeding is high, so this need for further study.

Multicolor imaging (MCI) based on confocal scanning laser ophthalmoscopy can gather more diagnostic information than traditional fundus photographs through utilizing three wavelengths of laser to scan posterior retina, which gain different layer reflected signal since the depth of penetration into retina is different for each wavelength. Currently, it provides important information and reference value for diagnose of different layer diseases on retina or choroid combining MCI with OCT, FAF, FFA and so on. However, there are still misunderstandings in the diagnosis of retinal diseases with MCI. Careful observation of retinal details in MCI, CFP and other imaging methods is more conducive to the correct diagnosis of fundus ophthalmopathy.

Objective:To investigate association between genetic polymorphism in the grainyhead-like 2 gene (GRHL2)and noise-induced hearing loss (NIHL)in the Chinese population.Methods:A matched case-control association study was employed,In which,3 790 workers exposed to continuous and steady-state occupational noise in a steel factory participated.The questionnaires were adopted to col-lect individual features and audiometry tests performed.In the sstudy,286 subjects were diagnosed as ca-ses,Which were each designated on the basis of the matched criterion,and 286 paired samples were se-lected finally.Noise intensity was measured according to the standards given in ‘Measurement of Noise in the Workplace’(Occupational Health Standard of the People’s Republic of China,GBZ /T1 89.8 -2007).Cumulative noise exposure (CNE)was calculated,according to monitoring data on A-weighed sound pressure level and employment time.Genomic DNA was obtained from peripheral blood samples using 2 mL DNA extraction Kit following the manufacturer’s protocol.Five single nucleotide polymor-phisms (SNPs)of GRHL2 were genotyped by multiplex SNP genotyping kit.The continuous variables and categorical variables were analyzed by t-test and chi-square test respectively.Multivariate Logistic re-gression was used to test the association between genetic frequency and disease status,with adjustments for the possible confounding variables.The haplotypes were established and their frequencies in the two groups were assessed by haploview and phase softwares.Results:All the five SNPs (rs373571 3, rs3824090,rs373571 4,rs373571 5 and rs61 1 41 9)were in Hardy-Weinberg equilibrium (HWE)(P >0.05).The subjects carrying rs373571 5 GG genotype had a higher NIHL risk than those carrying the GA genotype under the co-dominant model (OR =0.644,95% CI:0.442 -0.939,P =0.022)after ad-justment for height,blood pressure,drinking status and smoking status.After being stratified by CNE,in the CNE ≥ 98 dB (A)group,rs373571 5 polymorphism was associated with the NIHL under the co-dominant model (OR =0.509,95% CI:0.281 -0.923,P =0.026)after adjustment for height,blood pressure,drinking status and smoking status as well.However,no statistical significant difference was found in variant genotypes of the other SNPs between the case and control subjects.Four-locus (rs373571 3,rs3824090,rs373571 4 and rs373571 5)haplotypes were constructed,and no risk or protec-tive haplotypes was identified.Conclusion:It is suggested that GRHL2 polymorphisms may be associated with development of NIHL.

Objective To compare the simple cases of hand-foot-mouth disease(HFMD) with HFMD patients complicated with encephalitis and HFMD cases complicated with pulmonary edema (PE). To explore predictor factors of disease progression and unfavorable prognosis. Methods Forty-one EV71-infected children admitted to the Fuyang First People's Hospital in Anhui Province from March to May in 2008 were investigated in the research, who were classified as encephalitis-complicated cases ( encephalitis group, n = 15 ), PE-complicated cases ( PE group, n = 15 ) and simple cases (simple group, n= 11 ). Their clinical manifestation, laboratory findings, and immunophenotypes of peripheral blood lymphocyte were analyzed to find predictors associated with disease progression and unfavorable outcomes. Results The mortality rate in PE group was 66.7%, which was significantly higher than that in encephalitis group. Ninty-three point three percent cases in PE group and encephalitis group were younger than 3 years old, with statistic difference compared to simple group. Patients in PE group had higher total blood white cell (WBC) counts and higher absolute neutrophil counts and tended to have higher breathing rate, heart i'ate and glucose level than encephalitis group. The percentages of T cells and natural killer (NK) cells were significantly lower among patients complicated with encephalitis than simple HFMD patients.Conclusions PE is one predictor for poor prognosis. Factors correlated with unfavorable outcome include high WBC, high absolute neutrophil counts; elevated breathing rate, heart rate and glucose level. The immunophenotypes of peripheral blood lymphocytes can also predict the disease progression.

This study was aimed to investigate the antitussive, expectorant and antiasthmatic effects of aqueous extracts and the chemical split fractions ofMori Cortex. Cough mice models induced by ammonia water were used to observe the effect on arresting cough. The phenol red expectoration method in mice was used to observe the effect on expelling phlegm. Histamine and acetylcholine mixture induced asthma model was used to observe the effect on relieving asthma. Isolated trachea model was used to observe the effect on relieving spasm. Compared with the control group, the low, medium and high doses of aqueous extracts ofM. Cortex can obviously decrease the frequency of cough, increase phenol red output of trachea in mice, prolong the latent period of asthma in guinea pigs, and increase the antispasmodic rate. The medium dose had the best effect. The comparison between different chemical split fractions ofM. Cortex and the control group showed that the 30% and 50% ethanol fraction ofM. Cortex can obviously decrease the frequency of cough and prolong the latent period of cough induced by ammonia water in mice, increase phenol red output of trachea in mice (P<0.05 orP<0.01); and 30% ethanol fraction and fatty oil fraction can prolong the latent period of asthma in guinea pigs (P< 0.05 orP<0.01). In addition, 30% ethanol fraction can obviously reduce the degree of tracheal contraction. It had certain effect of relieving spasm. It was concluded that aqueous extracts ofM. Cortex had better effects on relieving cough, expectorant and antiasthma. The effective part was the 30% ethanol fraction, which was the dose equivalent of 1/3 of the medium dose. It had significant effect on relieving cough, expectorant and antiasthma. The effect was equivalent to the medium dose of aqueous extracts of M. Cortex.
