Objective To investigate the effects of azithromycin on hyperoxia induced lung injury in neonatal rats.Methods Ninety 2-day-old neonatal rats were randomly divided into 3 groups (30 cases in each group):air control group,hyperoxia model group,azithromycin treated group.The rats in air control group were exposed to indoor air,and the rats in hyperoxia model group and azithromycin group were exposed to 900 mL?L-1 O2 for 14 days.From 2-days-after birth,rats in treated group received intraperitoneal injection of azithromycin (200 mg?kg-1)per day,rats in air control group and hyperoxia model group received intraperitoneal injection of normal saline.Ten rats in each group were executed and their lung tissues were taken out and were observed under a optical microscope on the 3rd,7th,14th days from the start.The expression of interferon gamma(IFN-?),connective tissue growth factor(CTGF) and matrix metalloproteinase-9 (MMP-9) in the lung tissues were detected by immunohistochemistry.Results There was no expression of IFN-? positive cells in air control group,but the expressional intensity level was gradually enhanced as the time of inhaling hyperoxia prolonged in hyperoxia model group,it reached the peak on the 7th day,and then obviously declined on the 14th day,but still higher than that of air control group.The expressional intensity level of IFN-? in azithromycin treated group was lower than that of hyperoxia model group in each time segment,there were significant differences among them(Pa

Objective To discuss the valuable influence of the total-body massage on the facilitation of the rehabilitation for the women in puerperium.Methods Both Chinese traditional medical total-body massage and the biological information theories and its methodology were employed in dealing with 50 cases of puerperants without contraindications,who had labored naturally 12 hours before and who had received cesarean sections 48 hours before. The results were compared with the control group in which conventional preventive health care for puerperants was adopted.Results Notable differences exist in the aspect of lochia,defecation,lactation and emotions between the two groups.Conclusion Significant benefits can be obtained from the massage to facilitate the rehabilitation of the women in puerperium while promoting their quality of lives and broadening the coverage of services of the preventive health care for the puerperants.

ObjectiveTo observe effect of head and body acupuncture and moxibustion on stroke.Methods183 stroke patients were randomly divided into 3 groups, head acupuncture and moxibustion, body acupuncture and moxibustion, and head body acupuncture and moxibustion. After two months treatment, effects of 3 groups were evaluated.ResultsThere were no differences between head group and body group, body group and head body group, but there was significantly difference between head body group and head group (P<0.05).ConclusionThe head body acupuncture and moxibustion can gain the best clinical effect on stroke patients compared with simply head or body acupuncture and moxibustion.

Objective To investigate nursing students and nurses' knowledge, attitude and behaviors of standardized treatment of medical waste, so as to develop more constructive advices in future. Methods The survey was conducted in 80 nursing students and 85 nurses in one of the Beijing' s third level 1 class hospitals.The data was analyzed with SPSS 17.0 software. Results Nursing students' scores of knowledge, attitude and behavior were significantly lower than nurses' ( t =- 6.986, - 5.336, - 3.862 ; P ＜ 0. 05 ) ; Nursing students with higher education levels showed significantly higher scores of knowledge ( F =9. 992, P ＜ 0. 05 ), but there' s no significant difference with scores of attitude or behavior( F =1. 279,1. 595 ; P ＞ 0. 05 ) ; Nurses with different education levels, length of service and professional titles showed no significant difference with scores of knowledge, attitude and behavior(P ＞ 0. 05). Scores of nursing students and nurses in behavior were low, and needs to be raised. Conclusions Adequate knowledge is foundation and good attitude is propulsion, they two will be helpful to increase the quality of treatment of medical waste with systematic management and training of the hospital.

OBJECTIVE: To explore the effect of masking therapy for the early stage of the patients with noise-induced tinnitus,and imply the treatment for patients with noise-induced tinnitus. METHOD: Sixty-eight cases with tinnitus were studied. All the patients took the audiological examinations and tinnitus tests firstly, and accepted the masking therapy for 6 months. The therapeutic effiency was evaluated according to tinnitus handicap inventory (THI) and subjective visual-analogue scale (VAS). The minimum masking intensity was also evaluated. RESULT: The majority of the patients with noise-induced tinnitus (59 cases, 86. 8%) had tinnitus frequency of 4 kHz,and most of them (44 cases, 64. 7%) had positive residual inhibition tests. Tinnitus completely disappeared in 3 cases after masking therapy, and the efficiency of this treatment is 83. 8%. There was significant difference in the scores of THI and VAS before and after therapy(P<0. 01), and there was also significant difference in the minimum masking intensity (P<0. 01). CONCLUSION Masking therapy is the most important treatment for the patients in the early stage of noise-induced tinnitus. The therapeutic effiency is significant and should be promoted.

OBJECTIVE: To analyze and summarize nystagmus of patients with posterior canal benign paroxysmal positional vertigo (BPPV) in positioning test,and to improve the diagnosis and treatment of posterior canal BPPV (PSC-BPPV). METHOD: The present study was conducted on 175 patients who had unilateral BPPV of the posterior semicircular canal (PSC). Their positional nystagmus recorded by videnonystagmography in Dix-Hallpike test,roll test and roll over test were analyzed to summarize the characteristics of nystagmus on nystagmograph of PSC-BP-PV. RESULT: Of the 175 patients, lesion was located in the left PSC in 69 (39.4%) patients,the right PSC in 106 (60. 6%)patients. The nystagmus of patients with PSC-canalithiasis showed upward on the vertical phase of nystagmograph and orientated the different side on horizontal phase in the head hangging position. The horizontal phase pointed to the contralateral side in 47(26. 9%) patients, the ipsilateral contralateral side in 100(57. 1%) patients,no significant reverse ingredients in 28(16.0%) patients. When these patients returned to sit,139(79.4%) patients showed down beating positioning nystagmus, whereas 36 (20. 6%) patients with no nystagmus only had a short vertigo or dizziness. The horizontal phase of the 139 patients pointed to the contralateral side in 40(22. 9%) patients,the ipsilateral contralateral side in 68(38. 9%) patients,no significant reverse ingredients in 31(17. 7%) patients. In roll test,12 patients of the right PSC-BPPV presented an up-beating rotatory nystagmus when the head turned to right,and 5 patients of the left PSC-BPPV presented a down-beating rotatory nystagmus when the head turned to left. When the patients changed body from the left lateral position to the right lateral position in the roll over test, 74(42. 3%) patientsshowed vertical positioning nystagmus. In 30 patients who presented an up-beating nystagmus, there were 25(83. 3%) patientscame from the right PSC-BPPV. In 44 patients who presented a down-beating nystagmus, there were 36(81. 8%) patientscame from the left PSC-BPPV. The direction of the vertical nystagmus was highly correlated with the judgment about the side of the PSC-BPPV in roll over test (P<0. 01). CONCLUSION The patient with PSC-canalithiasis showed an uncertain direction in torsional nystagmus in Dix-Hallpike test,the diagnosis was mainly concern with the vertical nystagmus. When we found a rotatory nystagmus with much more up-beating nystagmus in roll test, it might be PSC-BPPV. We also can use the roll over test to diagnose the location of the otolith in which side of the PSC-BPPV.
