不同高压氧治疗方案对急性一氧化碳中毒受损心肌的疗效分析

Objective To investigate the effects of different hyperbaric oxygen ( HBO) treatment profiles on damaged myocardium induced by acute carbon monoxide poisoning. Methods One hundred and fifty-five serious cases of acute carbon monoxide ( CO) poisoning admitted into the hospital for treatment from October 2006 to March 2010 were randomly divided into the routine HBO treatment group (the routine group,75 cases) and the improved HBO treatment group (the improved group,80 cases). The treatment profile of the routine HBO treatment group: the patients were compressed for 20 min to the treatment pressure of 0.25 Mpa. Following stabilization at the said pressure, the patients breathed oxygen twice for 30 min plus 10 min, once a day. The whole treatment course consisted of 12 sessions, with the patients receiving HBO treatments from 9 to 68 times. The treatment profile of the improved HBO treatment group: the patients were given routine HBO treatment in the first 5 days, then, received improved HBO treatment, with a treatment profile of lower pressure (0.20 Mpa) , shorter oxygen-breathing time, lengthening of oxygen-breathing intervals and intermittent oxygen breathing. Total oxygen-breathing time was 4 times, each for 10 min plus 3 times each for 5 min. Then, the patients were decompressed to the surface following 20-min oxygen-breathing decompression. The patients received treatment for a succession of 3 days, then, had 1-day interval, and the whole treatment course consisted of 10 sessions. Changes in ST-T and myocardial enzymes of both the routine HBO treatment group and the improved HBO treatment group were measured and analyzed. Results ST-T recovery rate of the improved HBO treatment group increased (56% ,28% ) obviously, when compared with that of the routine HBO treatment group(P ＜ 0. 05). ST-T worse rate decreased significantly following HBO treatment on the 3rd and 6th days (21% and 25% on the 3rd day, 16% and 27% on the 6th day) respectively (P＜0.01). Statistical differences could be seen in the myocardial recovery rate and worse rate, when a comparison was made between them (P＜0. 05, P＜0. 01). Conclusions The improved HBO treatment profile showed better therapeutic effect on damaged myocardium induced by CO poisoning. This treatment profile should be used instead of other treatment profiles.

Abstract：

Objective To study the effects of HBO at different pressures on apoptosis following spinal cord injury in rats and also to investigate ideal pressure value of hyperbaric oxygen(HBO) on spinal cord injury (SCI). Methods The SCI model was established with Allen's weight dropping by using 90 SD rats. Then, the animals were randomly divided into 5 groups following SCI: the control group ( group A); the HBO treatment group at 0. 15 Mpa (group B); the HBO treatment group at 0. 20MPa (group C); the HBO treatment group at 0. 22 Mpa ( group D); the HBO treatment group at 0.25 Mpa ( group E). Segments of injured spinal cord were collected from the animals of the 5 groups for studies on the 3rd, 7th, and 14th days after injury. The apoptosis cells were labeled with Tunel and the neurologic function of the spinal cord was assessed in the open field ( the BBB score ). Results The number of Tunel - positive cells decreased considerably and the BBB score improved significantly in all the animals of the HBO groups when compared with those of group A ( P ＜ 0. 05 ). Same results were found when the group C, group D and group E were compared with group B, with statistical significance( P ＜0. 05). The number of Tunel-positive cells were decreased considerably and the BBB score improved significantly on 3rd and 7th days in group E, when compared with those of group C( P ＜ 0. 05 ), with statistical significance( P ＜ 0. 05 ). However, no statistical significance could be noted on the 14th day (P ＜0.05). Conclusions HBO could inhibit apoptosis in rats following spinal cord injury, which might be correlated with the increase of pressure within a certain range.

Abstract：

Objective To observe the effects of HBO therapy on cerebral edema, blood-brain barrier and neural behavioral scores, induced by brain trauma injury in rabbits with magnetic resonance imaging ( MRI). Methods Twenty-four rabbits were randomly divided into three groups: the sham operation group (n =5), with a skull window of only 8 mm in diameter; the control group (n = 10) , sustained with shock injury (shock intensity of 0.2 Mpa) following skull fenestration; the HBO group(n=90), also sustained with shock injury following skull fenestration, but with HBO treatment. Following the development of the model, MRI scans were made at 6th, 24th, 72nd, and 120th hours to calculate the volume of cerebral edema, apparent diffusion coefficient ( ADC), and neurological behavioral scores. Results After HBO treatment, neurological behavioral scores of the HBO group improved significantly, when compared with that of the control group (P＜ 0. 05). MRI showed that abnormality was not noted in the sham operation group. Before treatment, significant cerebral edema and damage of blood-brain barrier could be seen in both the HBO group and the control group. However, following HBO treatment, cerebral edema and blood-brain barrier damage of the HBO group recovered more rapidly, when a comparison was made between the groups (P＜0. 01) and ADC value of the HBO group was lower than that of the control group (P＜0. 05). Conclusions HBO could hasten recovery of the blood-brain barrier damage induced by cerebral damage with hydraulic impetus, reduce cerebral edema, significantly decrease symptoms of brain injury, and reduce disability rate.

Abstract：

Objective To investigate changes in the expression of Fas and caspase-3 in the brain of rats with acute CO poisoning and also to provide new evidence for pathogenic mechanism of delayed neuropathological sequelae (DNS) after CO exposure.Methods Fifty SD male rats were randomly assigned to the control group, the 1, 3, and 7 d CO exposure groups and the 7 d HBO treatment group, each consisting of 10 rats. HE, immunohistochemical staining and Western blot were performed to study the expression of Fas and caspase-3 in the brain tissue, following intoxication at various time points.Results The expression of both Fas and caspase-3 were very low in the control group. One day after CO exposure, the expression of both Fas and caspase-3 increased quickly and reached peak 3 days after exposure. No significant differences in both Fas and caspase-3 expressions could be noted between the 3 d and the 7 d exposure groups. For the HBO treatment group, the expression of both Fas and caspase-3 decreased more significantly (P<0.01) as compared with that of the 7 d exposure group, but was still higher than that of the control group(P<0.05). Changes in the expression of Fas and caspase-3 were closely correlated with the severity of brain injury.Conclusions The expression of Fas and apoptosis might be involved in the mechanism of DNS following CO poisoning. HBO seemed to play an important role in the alleviation of brain damage via decreasing the expression of Fas and inhibiting the apoptosis of cells.

目的 探讨高压氧对家兔随意皮瓣毛细血管增殖作用的机制.方法 建立家兔背部随意皮瓣模型,予高压氧治疗,观察3 d和7 d时对照组和高压氧组皮瓣的成活情况,皮瓣中毛细血管密度及血管内皮细胞生长因子(VEGF)、缺氧诱导因子(HIF-1)含量的变化情况.结果 3 d和7 d时,高压氧组皮瓣的成活面积明显高于对照组(P＜0.01);皮瓣毛细血管密度明显高于对照组(3 d时P＜0.05,7 d时P＜0.01);3 d和7 d时,高压氧组皮瓣VEGF表达明显高于对照组(P＜0.01),HIF-1、表达明显低于对照组(P＜0.05).结论 高压氧治疗提高随意皮瓣成活率的机制之一可能是通过增加皮瓣组织中VEGF的表达而促进新生毛细血管形成,高压氧治疗可下调皮瓣组织中HIF-1的表达.     

高压氧联合甲钴胺治疗糖尿病周围神经病变的疗效

目的 评价高压氧联合甲钴胺对糖尿病周围神经病变的疗效,探讨治疗糖尿病周围神经病变的有效方法.方法 378例糖尿病周围神经病变患者分为2组.治疗组198例,予高压氧联合甲钴胺治疗,高压氧疗法采用大型空气加压舱,治疗压力为0.2 Mpa(2.0 ATA),每日1次;甲钴胺500 μg,肌肉注射,每日1次.对照组180例,单独使用甲钴胺500 μg,肌肉注射,每日1次.2组患者疗程均为4周.结果 治疗组显效率、总有效率分别为40.9%和100%,明显高于对照组的17.3%及53.3%,2组间差异有统计学意义(P＜0.01);治疗组神经传导速度及血流动力学改善均明显高于对照组(P＜0.01).结论 高压氧联合甲钴胺对糖尿病周围神经病变的治疗效果显著,总有效率为100%,可作为糖尿病周围神经病变的常规治疗方法.     

早期高压氧治疗对急性颅脑外伤患者失语症的疗效观察

目的 研究早期高压氧(HBO)治疗对急性颅脑外伤患者失语症的疗效.方法 将2004年1月至2007年8月在我院住院的62例急性颅脑外伤患者分为HBO治疔组和常规治疗组,常规治疗组采用临床常规治疗,HBO治疗组在常规治疗的基础上,实施24～48次HBO治疗,并且在治疗结束后1年内每3个月进行1次随访.在治疗前、后分别采用西方失语成套测试法(western aphasia,WAB)检测并进行CT检查,对他们的语言功能和恢复情况进行评价和比较.结果 HBO治疗组显效率(83.8%)显著高于常规治疗组(54.8%),经x2检验P＜0.05;CT检查证实患者病变部位阻塞的血管已经恢复冉通或已获得重建.结论 早期HBO治疗有利于促进或恢复患者的语言功能.
