ABSTRACT
Objective To investigate the curative effects of old age severe chronic obstructive pulmonary disease (COPD) patients inhaled Glucocorticoids with the special devices (Turbuhaler).Methods Seventy-six cases of elderly patients with severe acute exacerbation of COPD patients (53 males,23 females) were divided into experimental group(n =38) and control group(n =38),respectively,according to the random number table.In 10 days of therapy,patients of experimental group inhaled budesonide powder of inhalation 0.2 mg twice daily;Control group inhaled oxygen atomization budesonide suspension 1mg twice daily.The changes of panting symptom were observed.Three months followed-up,the test team inhaled budesonide powder of inhalation 1 mg twice daily,control group stopped inhaling drugs,all patients of panting symptom were observed,also were six-minutes walking distance,the frequency of acute exacerbation and adverse reaction.Intent and compliance program data analysis were performed of the experimental data.Results At the end of the stage of therapy,panting symptom of two group patients were all improved (F =8.746,7.952 respectively,P ＜ 0.05) ; Wheezing score between the two groups 1,5,10 days of treatment differences were not statistically significant(P ＞ 0.05).But the incidence rate of adverse reaction in experimental group was significantly lower than that of control group(x2 =11.372,P ＜0.01),and the treatment costs of test team was significantly lower than that of control group(t =4.573,P ＜ 0.01).At the start of the follow-up period (week 0),two groups of acute exacerbation frequency,wheezing,peak expiratory flow and 6 minutes walking distance had no significant difference(P ＞ 0.05).When follow-up period was at tne end of 12 weeks.The test group of patients with acute exacerbation frequency was significantly lower than the control group(aF within grouP =9.343,aF between groups =16.343,the aF interaction =20.017 ; P ＜ 0.05),wheezing in the control group was significantly mitigate (bF within group =8.537,b F between groups =11.453,bF interaction =13.071 ; P ＜ 0.05),and peak expiratory flow rate than the control group improved significantly (cF within group =9.015,cF between groups =12.426,cF interaction =14.852 ;P ＜ 0.05),6 min walking distance increased significantly compared with the control group (d F within group =12.263,d F between groups =21.371,d F interactive =24.651 ; P ＜ 0.05),the differences were statistically significant.Conclusion Elderly patients with moderate to severe COPD inhaled Glucocorticoids,with the special devices(Turbuhaler),not only in acute exacerbation stage the panting symptom was controlled; but also in stable phase the frequency of acute exacerbation was decreased,and the exercise tolerance was improved.Curative effect is obvious withsafety and well-tolerated.
ABSTRACT
Objective To explore the curative effect of inhaled tiotropium upon patients of stable chronic obstructive pulmonary disease (COPD) complicated with pulmonary hypertension.Methods A total of 76 patients (Male/Female =51/25) of stable COPD complicated with pulmonary hypertension were recruited from January 2010 to June 2011.According to table of random digit,they were divided into test group (n =38,M/F =26/12) and control group (n =38,M/F =25/13).Patients of control group inhaled formoterol powder 4.5 μg bid,took oral theophylline sustained-release tablets 0.1 g hid.According to the demand of patient's condition,anti-infective agents and sticky phlegm lyticagent were used.Patients of test group inhaled tiotropium dry powder (18 μg,qd) in addition to the above regimen.All changes in six-minute walk test (SMWT),pulmonary arterial systolic pressure and panting symptom score were recorded at the end of 16 weeks and compared with the baseline.The primary endpoint was the changes in exercise capacity as assessed by SMWT and pulmonary arterial systolic pressure.Safety and tolerance were also investigated.Intent-to-treat and per-protocol analyses were performed.Results After a follow-up period of 16 weeks,both pulmonary arterial systolic pressure and panting symptom score decreased and SMWT walking distance increased (45 ± 16) m in the test group.Compared with the control group,the difference had statistical significance (P ＜ 0.05) and obvious adverse reaction did not occur.Conclusions For patients of stable COPD complicated with pulmonary hypertension,inhaled tiotropium dry powder decreases pulmonary pressure to various extents and improves exercise tolerance and panting symptom.And tolerance is satisfactory.
ABSTRACT
The present paper deals with the effect of impulse noise, which is produced by launching of miniature tactical missiles, on hearing of guinea pigs situated in the control room of the missile launching vehicle. 20 normal hearing guinea pigs are placed in the control room in which impulse noise level is 160-170dB (sound pressure level) and duration is longer than Is. 48h after sound exposure, the mean threshold shift is 2 dB, and threshold shift of 2/40 ears is greater than 10dB. Histological observation reveals that cochlear hair cells are undamaged in 15 ears. Howeves, staining on bloc shows hydrops of cochlear partition in 5 ears.
ABSTRACT
Objective To investigate the possible role of leukocytes, a important cellular component of the blood, in the induction of microcirculatory disturbances in noise-exposed cochleae. Methods Guinea pigs were exposed to a 4 kHz narrow band noise at 115 dB SPL for 4 hours, and the exposed cochleae were collected at 2 or 4 days after the noise exposure. Several techniques (cell viability assay, fluorescent labeling for blood plasma and for hair cell nuclei) were used to examine morphological changes in microvessels in the spiral lamina and in the stria vascularis as well as the hair cell nuclei. Results In noise-exposed cochleae, aggregatad leukocytes were found in the vessels of the spiral lamina. In the up-stream of the vessels with aggregated leukocytes, red blood cells were tightly packed, causing an increase in vessel diameters. Most leukocytes were located within the lumen of vessels, but some of them infiltrated the spiral lamina, usually alongside the vessels. Cell viability, assessed by trypan blue staining, showed that these plugged leukocytes lost their viability. In contrast, no leukocytes aggregated in the vessels of the stria vascularis, nor did leukocytes lose their viability. Conclusion In the cochleae exposed to intense noise, leukocytes were trapped in the vessels of the spiral lamina, leading to disturbance of blood flow. The involvement of leukocytes in local damaging processes and the fate of leukocytes need further studies.
