Objective To discuss the diagnosis and treatment of pulmonary contusion. Methods A retrospective study was carried out in 132 cases of severe pulmonary contusion (injury severity score ≥20) from February 1993 to December 2003. Results Of all, 107 cases (81.1%)survived and 25 (18.9%)died. Conclusions Chest X-ray and CT are reliable for the diagnosis of pulmonary contusion. The important methods include keeping airway clear, progressively treating shock and reasonably applying ventilation, steroids as well as antibiotics. The early diagnosis and the prompt treatment of the associated injuries are key to higher cure rate.

Objective To conduct an empirical analysis of constitutes and changes of type 2 diabetes patients′ hospitalization expenses and find out the differences and influencing factors so as to provide hospitals and related departments with the decision basis of controlling medical costs, arranging medical resources and optimizing systems.Methods Information of type 2 diabetes patients who had been admitted to a certain first-class grade one hospital in Ningxia from 2013 to 2016 were collected and categorized.Hospitalization costs and influencing factors of the patients were comprehensively analyzed through descriptive statistics, variance analysis and regression analysis.Results The medicine and examination costs as the constitutes of hospitalization expenses were too high.Gender, length of stay, age and diabetic complications were main contributory factors of type 2 diabetes patients′ hospitalization expenses.Conclusion The costs of hospitalization of patients with type 2 diabetes are unreasonable and need to optimize.Type 2 diabetes patients′ hospitalization expenses should be effectively controlled and medical resources should be reasonably used through standardizing treatment behavior, shortening length of stay, intensifying publicity and education, enhancing prevention and reinforcing follow-ups, expanding health insurance coverage and upgrading its level.

Objective To determine the changes of patients with severe pulmonary contusion and the relationship among the serum level of alpha-granular membrane protein (CD62p), the severity of injury and prognosis. Methods The serum level of CD62p, was measured in 45 patients with severe pulmonary contusion on hour 2, hour 12,day 1,3,7 after injured. Forty-five patients were divided into two groups: the survive group and the death group. The levels of CD62p between two groups were compared. Results The serum levels of CD62p in patients with severe pulmonary contusion on 12 hours, 1,3 days after injury were higher than those on 2 hours (P<0.05). The serum levels of CD62p in the survive group and death group on 2 h, 12 hours after injury were higher than those in the control group(P<0.05), and the serum levels of CD62p in the death group were higher than those in the survive group. Conclusion It was helpful in judging the severity of head in jury and prognosis to determine the serum levels of CD62p in patients with severe pulmonary contusion.

ObjectiveTo explore the effect of low frequency or high frequency repetitive transcranial magnetic stimulation (rTMS) on right Broca's homologue in stroke patients with nonfluent aphasia. MethodsFrom January, 2019 to August, 2022, 80 inpatients in Beijing Bo'ai Hospital were randomly divided into control group (n = 20), sham stimulation group (n = 20), low-frequency (1 Hz) rTMS (LF-rTMS) group (n = 20) and high-frequency (10 Hz) rTMS (HF-rTMS) group (n = 20). All the patients received routine language therapy. LF-rTMS group and HF-rTMS group received ten days of rTMS (1 Hz or 10 Hz), and the sham group received ten days of sham rTMS. The Western Aphasia Battery (WAB) was used to evaluate the language function before, after treatment, and two months after treatment. ResultsBefore treatment, there was no significant difference in the scores of WAB among four groups (P > 0.05). All the scores improved in the four groups immediately after treatment and two months after treatment (P < 0.05). Compared with immediately after treatment, all the scores of WAB improved in LF-rTMS group (P < 0.05), and the scores of recall, name and aphasia quotient (AQ) improved in HF-rTMS group (P < 0.05) two months after treatment. Immediately after treatment, the scores of content and fluency, auditory comprehension and AQ were higher in LF-rTMS group than in HF-rTMS group (P < 0.05). Two months after treatment, the scores of content and fluency were higher in LF-rTMS group than in HF-rTMS group (P < 0.05). ConclusionBoth 1 Hz and 10 Hz rTMS could improve the language function of stroke patients with nonfluent aphasia, especially 1 Hz.
