Objective To study clinical features of severe craniocerebral injuries complicated by upper cervical vertebral injuries so as to have a deeper understanding and higher vigilantness. Methods Twenty-nine cases of severe craniocerebral injuries complicated by upper cervical vertebral injuries were clinically analyzed. Results Injury causes included traffic accident in 26 cases, fall in one, rolling down in one and mine collapse in one. Treatment results showed that 16 cases survived and 13 died. As for Glasgow Outcome Scale (GOS) score, two cases were ranked at grade Ⅴ, seven at grade Ⅳ, six at grade Ⅲ, one at grade Ⅱ and 13 at grade Ⅰ. Conclusions The severe craniocerebral injuries complicated by upper cervical vertebral injuries are critical and complex mainly because the severe craniocerebral injuries can be paid more attention and diagnosed and treated early while the upper cervical vertebral injuries are easy to be neglected, as gives rise to missed injuries, lack of timely management and high mortality. Therefore, various severe complications are liable for deaths.

Objective To study on NGF positive cells changes by the action of Danshen and explore the correlation between time and amount of NGF after traumatic brain injury (TBI)in rat.Methods72 rats were randomly divided into 3 groups,including sham group,brain injury and Danshen therapy group.TBI rat models were made by fluid percussion.NGF was determined on the 3rd,7th and 14th day after TBI.ResultsNGF positive cells after traumatic brain injury in brain reached the maximum level at the 3rd day(1.29±0.61),and it decreased since the 7th day(2.03±0.42),and it decreased to the lowest level on the 14th day (0.87±0.23).NGF positive cells after traumatic brain injury treated by Danshen were more than those patients who were treated without Danshen(1.77±0.54,3.35±0.37,0.65±0.21 vs 0.75±0.31,1.58±0.52,0.49±0.36,P＜0.05～0.01).ConclusionsThe expression of NGF was significantly increased in brain damaged tissues.This may be served as a useful marker of diagnosis in time-course of brain leison.Danshen injection can be used to protect brain after traumatic brain injury.

Objective: To investigate the clinical characteristics and surgical results of patients with chronic subdural hematoma (CSDH) in different age groups. Methods: 150 CSDH patients admitted to our hospital from January 2014 to January 2019 were selected as the research objects, and their clinical data were reviewed and collected. According to different age , they were divided into three groups: the <55 year old group (n=46), the 55-70 year old group (n=62), and the >70 year old group (n=42). The imaging examination results and clinical manifestations of three groups of patients in different age groups were compared. Combined with patients' wishes and surgical indications, 150 patients were treated with traditional burr hole and drainage and modified operation. The results of different operation methods in three groups were compared. Results: The incidence of headache/dizziness in the 55-70 year old group was higher than that in >70 year old group (P<0.05). The incidence of language disorder in the 55-70 year old group and >70 year old group was higher than that in <55 year old group , with statistically significant difference (P<0.05). The incidence of limb paralysis in the 55-70 year old group and the >70 year old group was higher than that in <55 years old group, with statistically significant difference (P<0.05). The incidence of mental disorders in the >70 year old group was higher than that in 55-70 year old group and <55 year old group, with statistically significant difference (P<0.05). The incidence of fecal incontinence in the >70 year old group was higher than that in 55-70 year old group and <55 years old group, with statistically significant difference (P<0.05). The imaging examination results of the three groups showed significant differences (P<0.05). According to the estimation of the amount of hematoma by the Dutian (DOTA) formula, the amount of hematoma in the group of >70 years old was significantly higher than that in the group of <55 years old and 55-70 years old, with statistically significant difference (P<0.05). Among the three groups, the proportion of patients with good prognosis after modified operation was higher than that of traditional operation, and the recurrence rate was lower than that of traditional operation, with statistically significant difference (P<0.05). The proportion of good prognosis and recurrence rate in group >70 years old were lower than those in the group of <55 years old and 55-70 years old (P<0.05). Conclusions CSDH patients of different ages have different characteristics in imaging examination results and clinical manifestations. Traditional burr hole drainage and modified operation can achieve certain results, but modified operation is more effective and can reduce the incidence of postoperative complications, which is worth popularizing.
