ABSTRACT
BACKGROUND: At present, common therapies of obstructive sleep apnea syndrome (OSAS) are uvulo-palato-pharyngoplasty and nasal continuous positive airway pressure (N-CPAP). The effective rate of surgical treatment was 50% and the prostecdtive efficacy is decreased gradually. As to treatment with breathing machine, some of the patients can not adapt to it.OBJECTIVE: To investigate the effects of auricular acupoint pressing therapy on clinical indexes of patients with OSAS and its clinical effect,and analyze the possible mechanism.DESIGN: Randomized control observation.SETTING: Department of Acupuncture and Department of Respiration,Second Hospital of Hebei Medical University.PARTICIPANTS: Forty-five outpatients with OSAS between April 2001 and April 2004, who were diagnosed as OSAS in the room of sleep-monitoring of Department of Respiration, were selected from the Clinic of Respiration, Second Hospital of Hebei Medical University, including 44 males and one female. All subjects were randomly divided into treatment group (n=30) and control group (n=15).METHODS: ①Patients in the treatment group were treated by auricular acupoint pressing therapy, acupoint-locating: shenmen, sympathesis, subcortex, heart, lung, spleen, kidney, anterior ear lobe. Each acupoint was pressed about 10-20 times with 3-5 times every day and 10 days as onecourse. Patients in the control group were treated with placebo and orally took 100 mg of Vitamin C three times a day. Patients in both groups were detected by 7hour nocturnal polysomnography before treatment and 10 days after the treatment, and the curative effects were evaluated.②Criteria of the curative effects on clinical symptoms: Effective: clinical symptoms such as dizzy,somnolence, oppressed chest and obstructing etc. were significantly ameliorated with nocturnal times decreased from 4-5 times to once or none and awake times decreased from 4-5 to once or none. Valid: clinical symptoms were improved. Invalid: no amelioration was found in clinicalsymptoms.MAIN OUTCOME MEASURES: Changes of clinical symptoms before and after the treatment and hypopnea index (HI), apnea index (AI), apnea hypopnea index (AHI), minimum blood oxygen saturation as well as the longest apnea time detected by polysomnography were observed.RESULTS: A total of 45 patients with OSAS were involved in the analysis of results, and no one withdrew from the study.①The clinical symptoms in auricular acupoint treatment group were significantly ameliorated than control group. In the treatment group, 17 patients were effective (56.7%), 12 patients were valid and one patient was invalid. The clinical symptoms in the control group were not improved before and after the treatment, and there were significant differences between the treatment group and control group (P ＜ 0.05). ②Comparison in each inspecting indexes by polysomnogram: those in the auricular pressing therapy group were remarkably different from those in the control group after treatment (P ＜ 0.001). There was no significant difference in all indexes of the control group between and after the treatment (P ＞ 0.05).③The differences in AI, HI, AHI, minimum blood oxygen saturation as well as the longest apnea time of the auricular pressing treatment group after the treatment were markedly different from those before treatment [(65.25±7.44), (53.69±10.80) times/hour; (72.40±7.92), (59.22±10.55) times/hour; (9.46±2.6), (6.5±2.9) times/hour; (73.3±4.8)%,(77.67±3.78)%; (90.16±33), (45.33±24.69) s,P ＜ 0.001]. Among them, the maximum decrease of AI was 19.3 times/hour, the maximum decrease of AHI was 17.8 times/hour, the maximum decrease of HI was 12.9 times/hour and the maximum increase of blood oxygen saturation was 7% CONCLUSION: Auricular acupoint pressing therapy, in the treatment of OSAS, can significantly ameliorate the AI, HI; AHI, minimum blood oxygen saturation as well as the longest apnea time with better curative effects.
ABSTRACT
Objective To investigate changes of platelet activation in the elderly patients with obstructive sleep apnea-hypopnea syndrome(OSAHS)before and after the application of nasal continuous positive airway pressure(nCPAP). Methods Ninety patients diagnosed as OSAHS by polysomnography(PSG)were selected as trial group,30 non-OSAHS by PSG were as control group, and 16 severe OSAHS patients were treated by nCPAP and taken as nCPAP therapy group. GMP-140 and GPⅡb/Ⅲa were measured by ELISA and compared in these groups. Results Plasma levels of GMP-140 and GPⅡb/Ⅲa of patients with moderate and severe OSAHS were (16.6?2.3)?g/L vs (18.9?3.1)?g/L, and 38 468?952/ 49 673?1037 vs 39 867?1264/50 899?2476 respectively; and those of control group were (14.8?2.1) ?g/L, 37 672?769/ 48 469?1672 respectively.Plasma levels of GMP-140 and GPⅡb/Ⅲa were significantly higher in patients with moderate to severe OSAHS than those in control group(P
ABSTRACT
AIM:To look for a better method to deal with interstitial lung disease,interferon-gamma(IFN-?)combined with methylprednisolone(M-pred)to influence human embryonic lung fibroblast on proliferation,collagen synthesis and the expression of transforming growth factor-?1(TGF-?1)protein and mRNA were investigated.METHODS:Exponentially growing cells were preincubated for 48 h before harvested.The microculture tetrazolium(MTT)assay was used to measure the inhibition ratios of M-pred combined with different concentrations of IFN-?.The expression of proliferation cell nuclear antigen(PCNA)was detected by immunocytochemical analysis.Hydroxyproline kit was adopted to detect collagen synthesis.The expressions of TGF-?1 mRNA and protein were detected respectively by RT-PCR and Western blotting.RESULTS:Methylprednisolone,IFN-? as well as the combination of methylprednisolone and IFN-? inhibited the proliferation of HELF and the expression of PCNA in comparison with control group(P
