Objective To explore the clinical value of 3-dimensional digital subtraction angiography(3D-DSA)in the diagnosis and therapy of intracranial aneurysms.Methods 2-dimensional digital subtraction angiography (2D-DSA)and 3D-DSA was performed respectively on 1 53 patients,including 1 5 1 cases with spontaneous subarachnoid hemorrhage (SAH),1 case with headache and 1 case with cerebral infarction;Meanwhile,to compare the difference in diagnosis of intracranial aneurysms between 2D-DSA and 3D-DSA.Results 1 12 patients(125 pieces)with intracranial aneurysms were detected on 2D-DSA,its detecting rate was 73.2%(1 12/1 53 );136 patients(1 52 pieces)with intracranial aneurysms were detected on 3D-DSA,its detecting rate was 88.9%(136/1 53)(χ2 =12.254,P <0.05).The displaying rate of 3D-DSA for the relationship between carrying tumor artery and aneurysms and the necks of aneurysms was 100%(1 52/1 52),however,the displaying rate of 2D-DSA for that was 61.6%(77/125)(χ2 =63.993,P <0.05). Conclusion 3D-DSA can improved the diagnostic accurate rate of intracranial aneurysms,it is important in chosing the therapeutic regimen.

Objective To explore the promoting effects of bio-polymer composite film as a micro-skin auto-graft covering on wound healing. Methods The full thickness skin defect models were made on both sides of 30 experimental rabbits. Then, the rabbits were randomly divided into experimental group and control group. In the for-mer group, the side was covered with chitosan/glucomannan composite membrane and in the latter, the side cov-ered with acelluar porcine skin after micro-skin autograft. We obtained wound tissues at week 1 , 2, 3, 4 and 5 af-ter operation. The conditions of wound healing were observed, the rate of wound healing was calculated, HE stain-ing was made, and PCNA and CD31 were detected by immunohistochemistry. Results (1) During 2~4 weeks af-ter operation, the rate of wound healing in the experimental group was significantly higher than that of the control wound (P<0.01). (2) The amount of neutrophil in experimental group was less than that of the control after oper-ation. (3) During 1 ~ 2 weeks after operation, the expression of PCNA in the experimental group was higher than that of the control group (P < 0.01), but lower than the control wounds during 1 ~ 2 weeks after operation (P <0.01). (4) During 1 ~ 5 weeks after operation, the expression of CD31 in the experimental group was higher than that of the control group (P < 0.01). Conclusion Chitosan/glucan-mannan composite membrane as a micro-skin autograft covering may promote wound healing.

Stroke self-management model is still in the exploratory stage, lacking of systematic and well-informed intervention measures. The concept of stroke self-management, assessment tools, influencing factors and intervention measures and methods based on influencing factors were reviewed in this paper. The purpose of this study was to provide some reference for the formulation of stroke health management intervention program and the development of rigorous stroke health management practice research.

Total knee replacement surgery is commonly used in end-stage diseases of the knee. It is important for improving surgical efficacy and patient satisfaction by promoting early rehabilitation of patients and improving knee function.

Objective:Discuss and analyze the mechanisms of spine fine adjusting through the observation of the therapeutic effect in treating cervical spondylotic radiculopathy(CSR)and the conversion of cervical curvature.Methods: Randomly divide 106 CSR patients into two groups–manipulation therapy group and traction therapy group,53 for each.Judge the therapeutic effect by evaluation scales and measure the cervical curvature on X-ray photographs.Results:The symptoms and physical signs of the patients in both two groups have been improved(P

Objective: To systematically evaluate the effectiveness of epidermal growth factor (EGF) in treating patients with inhalation injury by meta analysis. Methods: Databases including PubMed, Cochrance Library, and Embase were searched using key words " inhalation injury, smoke inhalation injury, epidermal growth factor, and EGF" , and Chinese Journals Full-text Database, China Biology Medicine disc, VIP Database, and Wanfang Database were searched using key words in Chinese version "吸入性损伤,表皮生长因子" to obtain the randomized controlled trails about EGF published publicly in the treatment of patients with inhalation injury from the establishment of each database to December 2017. The measurement indexes included content of total protein and albumin, colloid osmotic pressure (COP), the number of total cells, percentages of neutrophils, lymphocytes, and fibroblasts in bronchoalveolar lavage fluid (BALF), the time of disappearance of pulmonary symptoms, the time of exfoliation of necrotic mucous membrane, the time of removal of tracheal tube, the amount of respiratory secretions, and the incidence of lung infection. Meta-analysis was conducted by RevMan 5.3 statistical software. Results: A total of 6 trials involving 375 patients were included, with 182 patients in group EGF who received EGF treatment and 173 patients in conventional treatment group who received conventional treatment. All of the 6 trails had unclear risk of bias. The content of total protein and albumin and COP in BALF of patients in group EGF were lower than those in conventional treatment group, with standardized mean differences (SMDs) respectively -9.37, -26.77 , and -8.13 [with 95% confidence intervals (CIs) respectively -14.11--4.63, -41.85--11.69, -9.54--6.73, P<0.001]. The number of total cells and percentages of neutrophils and lymphocytes in BALF of patients in group EGF were lower than those in conventional treatment group, while the percentage of fibroblasts in BALF of patients in group EGF was higher than that in conventional treatment group, with SMDs respectively -20.22, -13.08, -12.28, 2.99 (with 95% CIs respectively -22.27--17.66 , -14.76--11.40, -13.86--10.70, 2.48-3.50, P<0.001). The time of disappearance of pulmonary symptoms, the time of exfoliation of necrotic mucous membrane, and the time of removal of tracheal tube of patients in group EGF were shorter than those in conventional treatment group, with SMDs respectively -1.05, -1.22 , -1.11 (with 95% CIs respectively -1.36--0.74, -1.54--0.91, -1.39--0.82, P<0.001). The amount of respiratory secretions of patients in group EGF was lower than that in conventional treatment group, with SMD -1.44 (with 95% CI -1.90--0.98, P<0.001). The incidence rate of pulmonary infection of patients in group EGF was lower than that in conventional treatment group, with relative risk 0.46 (with 95% CI 0.24-0.89, P<0.05). There may be publication bias in the content of total protein, albumin, and COP in BALF (P<0.05), while the time of disappearance of pulmonary symptoms, the time of exfoliation of necrotic mucous membrane, and the time of removal of tracheal tube showed no significant publication bias (P>0.05). Conclusions Conventional treatment combined with EGF therapy can reduce respiratory inflammation of inhalation injury, promote restoration of respiratory epithelium, shorten the time of removal of tracheal tube, reduce the incidence of pulmonary infection of patients, and therefore has good effect on inhalation injury.
