Objective:To study the clinical effects of modified surgical method with H-uvulopalatopharyngoplasty(H-UPPP)and traditional surgical method in the treatment of obstructive sleep apnea hypopnea syndrome(OSAHS)in children.Methods:The clini-cal data of 364 pediatric patients with OSAHS were retrospectively analyzed.The patients were divided into 2 groups and treated by low-temperature plasma knife radio frequency ablation for bilateral tonsil removal combined with H-UPPP(group A,n=204)and low-temperature plasma knife radio frequency ablation only(group B,n=160)respectively.The operative time,intraoperative bleed-ing,postoperative secondary bleeding,VAS of pain following operation,postoperative traumatic white film shedding time,OAH1,LSaO2,ESS scores and complications of the 2 groups were compared.Results:In group A the operative time,intraoperative bleed-ing,VAS,OAHI and ESS scores were lower than those in group B(P＜0.05),wile postoperative traumatic white film detachment time and LSaO2 were higher(P＜0.05).No statistically significant difference in terms of the number of cases of postoperative seconda-ry bleeding and complications was observed between the 2 groups(P＞0.05).Conclusion:The combination of low-temperature plas-ma radio frequency ablation and H-UPPP for the treatment of OSAHS may provide clear intraoperative view,and may improve the treatment effects.

Objective To investigate the clinical efficacy of comprehensive hyperbaric oxygen (HBO) in the treatment of the patients with sudden hearing loss .Methods Totally, 80 patients with sudden hearing loss who were admitted into our hospital for treatment from June 2015 to March 2017 were selected as research subjects, and were divided into the observation group (n =40) and the control group (n =40), in accordance with the sequence of admission.The control group was given volume expansion to improve hemorheology , vasodilator to improve microcirculation, glucocorticoids, neurotrophic drugs and ginkgo biloba extract dripping pills, while the observation group received HBO in addition to the treatment received by the control group .One course of treatment for all patients in the 2 groups was 10 days, and following 3 courses of treatment, changes in hearing and clinical efficacy before and after treatment for the patients of the 2 groups were compared between the 2 groups.Results Following treatment for 3 courses for the observation group , 4 cases were cured, 21 cases were markedly effective , 10 cases were effective and 5 cases were ineffective, with a total effective rate of 87.5％, while for the control group, no cases were cured, 5 cases were markedly effective, 22 cases were effective and 13 cases were ineffective, with a total effective rate of 67.5％.Statistical significance could be seen, when comparisons were made between the observation group and the control group (P <0.05).Before treatment, there was no significant differences in full frequency hearing loss for the patients of 2 groups (P >0.05).After 2 courses of treatment, the value of low frequency hearing for the observation group increased more significantly, as compared with that of the control group [(37.39 ±5.77) vs (23.91 ±4.08) dB,P <0.05], however, there were no statistical differences in the increased values of high frequency hearing , when comparisons were made between the 2 groups (P >0.05).After 3 courses of treatment, the increased values of both low frequency and high frequency hearing for the patients of the observation group were all significantly better than those of the control group [ low frequency: (45.99 ±5.98) vs (36.79 ±5.72) dB; high frequency:(19.63 ±3.94) vs (9.70 ±2.17)dB, P <0.05].Conclusions Comprehensive HBO treatment could effectively improve the hearing level of the patients with full frequency sudden hearing loss , which was worth further clinical popularization .

OBJECTIVE:To investigate the effect of preoperative use of high-dose simvastatin on the pulmonary artery pres-sure in congenital heart disease with left-to-right shunt. METHODS:86 patients with left-to-right shunt congenital heart disease who were planned to implement interventional occlusion therapy were randomly divided into control group(43 cases)and observa-tion group(43 cases). Patients in both groups were given digitalis,diuretics,anticoagulants and other basic treatments;On this basis, control group received Sildenafil citrate tablet,25 mg,3 times a day,orally given 1 h before a meal;observation group received Simvastatin tablet 80 mg,once every evening,orally. The treatment course for both groups was 7 d. Mean pulmonary hypertension (mPAP),N terminal prohormone brain natriuretic peptide (NT-proBNP),arterial oxygen saturation (SaO2),arterial oxygen ten-sion(PaO2),pulmonary blood circulation ratio(Qq/Qs),pulmonary pressure variation(Rp/Rs),pulmonary vascular resistance in-dex(PVRi)before and after treatment in 2 groups were observed,and related indicators of liver functions [alanine aminotransfer-ase (ALT),aspartate aminotransferase(AST)] and myocardial enzymes [lactate dehydrogenase (LDH),creatine kinase MB(CK-MB)] were detected. The incidence of adverse reactions were deteted. RESULTS:Before treatment,there were no significant differ-ences in mPAP,NT-proBNP,SaO2,PaO2,Qq/Qs,Rp/Rs,PVRi,ALT,AST,LDH and CKMB levels in 2 groups(P>0.05). Af-ter treatment,mPAP,NT-proBNP,Rp/Rs and PVRi levels were significantly lower than before,SaO2,PaO2,and Qq/Qs levels were significantly higher than before and Qq/Qs level in observation group was higher than these in control group.The difference was statistically significant(P<0.05). There was 1 patient showed severe liver injury in observation group and exited the test;the other 85 patients showed no obvious adverse reactions,with successful surgery and good prognosis. CONCLUSIONS:The preoper-ative use of high-dose simvastatin shows obvious effect on controlling mean pulmonary hypertension,reducing mPAP,NT-proB-NP,Rp/Rs and PVRi levels and increasing SaO2,PaO2,and Qq/Qs levels before operation,with good safety.
