Objective To investigate the relationship between the levels of serum glial fibrillary acidic protein (GFAP) ,ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) ,CT findings and outcome in patients with severe traumatic brain injury .Methods En-zyme linked immunosorbent assay (ELISA) was conducted to detect the serum level of GFAP and UCH-L1 in 62 patients with se-vere traumatic brain injury at the time of 12 h and 36 h after the trauma .CT scans of the brain were obtained within 12 h of injury . Outcome was assessed by glasgow outcome scale (GOS) at 6th month .The relationship between GFAP ,UCH-1 ,CT findings and outcome were analyzed .56 healthy persons were selected as control group .Results The concentrations of serum GFAP and UCH-L1 of patients were significantly higher than those of the control group (P< 0 .05) ;GFAP levels were higher in patients with mass lesions than in those with diffuse injury while UCH-L1 levels were higher in patients with diffuse injury (P< 0 .05) ;the levels of GFAP and UCH-L1 of patients with unfavourable outcome(GOS 1 - 3 scores) were significantly higher than those of patients with favourable outcome(GOS 4 - 5 scores) ,and the concentrations of biomarkers were significantly negatively correlated with outcome . Conclusion Serum levels of GFAP and UCH-L1 are good predictors for severity and outcome in severe traumatic brain injury (TBI) .The levels of GFAP and UCH-L1 could reflect different injury pathways which were different in patients with mass lesions and diffuse injury remarkbly .GFAP and UCH-L1 could provide better characterization of subjects for specific types of cellular dam -age than that obtained with CT alone .

Objective To investigate the expression of C/EBP homology protein (CHOP) in peripheral brain tissue of patients with severe traumatic brain injury (TBI) and its correlation with the injury severity.Methods The study included peripheral brain tissues of 41 TBI patients (TBI group).Another 16 autopsy specimens succumbed to other diseases (except for TBI or other central nervous system diseases) were selected as controls.The control group and TBI group were subdivided into immaturity group (≤18 years),adult group (18-59 years) and elderly group (＞59 years).According to Glasgow Coma Scale (GCS) on admission,TBI group was classified as severe TBI group (GCS of 6-8) and particularly-severe TBI group (GCS of 3-5).CHOP expression in peripheral tissues after TBI was compared in between different age,gender and GCS.Nerve cell apoptosis was detected by TUNEL technique and correlation between CHOP level and apoptotic number was analyzed.Results There were no age and gender differences regarding CHOP expression in control group (P ＜ 0.05).Compared with control group,expression of CHOP presented notable up-regulation in TBI group (P ＜ 0.05).Expression of CHOP presented no gender difference in TBI group (P ＞ 0.05),but its expression was lower in the aged than in adult or immaturity (P ＜ 0.05) as well as notably higher in particularly-severe TBI group than in severe TBI group (P ＜ 0.05).Nerve cell apoptosis in TBI group was far greater in number than that in control group (P ＜0.05).A positive correlation was observed between CHOP level and apoptotic index (r =0.72,P ＜ 0.05).Conclusion Expression level of CHOP after TBI is closely related to the injury severity and nerve cell apoptosis,but the apoptosis pathway induced by CHOP may not be a major factor in secondary brain injury after TBI in the aged patients.

Objective Aim to explore the effect of hyperglycemia on the expression of glucose transporter 1 (GLUT-1)in rats at the acute phase of traumatic brain injury.Methods Adult male SD rats were randomly divided into 3 groups: normal control group, traumatic brain injury group and insulin treated group.The blood glucose concentration of the rats was measured before and after injury.The expression of GLUT-1 gene and protein in the injured and uninjured cortex was detected by reverse transcription polymerase chain reaction (RT-PCR) and western-blot.The apoptosis in the injured and uninjured cortex were detected by TUNEL staining.Results The blood glucose concentration increased markedly in traumatic brain injury group.The expression of GLUT-1 gene and protein in the injured cortex decreased in both the traumatic brain injury group and the insulin treated group.In contrast, the expression of GLUT-1 gene and protein significantly increased at 12 h, 24 h, 48 h, 72 h after injury in the insulin treated group compared with control(P＜0.01).The number of apoptotic cells in the insulin treated group were significantly larger than that in the traumatic brain injury group at each time point(P＜0.01).However, The number of apoptotic cell death remained unchange in the uninjured cortex in each group(P＞0.05).Conclusions The hyperglycemia after traumatic brain injury may increase the apoptotic cells in the injured brain through decreasing the expression of GLUT-1.

BACKGROUND:More recently, the focus has been on searching for a compound Chinese medicine for reinforcing kidney, which cannot only inhibit bone absorption, but also promote osteogenesis to protect against osteoporosis. OBJECTIVE:To explore effects of drug serum of Jianbuhuqian pil s on proliferation and function of osteoblast-like cel s in vitro. METHODS:Twenty-four adult female Sprague-Dawley rats were randomly divided into low-dose, medium-dose, high-dose and normal saline groups, and given intragastric administration of 1.5, 3.0, and 6 g/kg Jianbuhuqian pills and equal volume of normal saline, respectively twice daily for 1 week. At 1 hour after final gavage, rats were decapitated to prepare drug sera used for culturing osteoblast-like cells. At 24, 48 and 72 hours of culture, the cellular morphology was observed, as well as the cell proliferation and alkaline phosphatase activity was detected by MTT assay and alkaline phosphatase staining, respectively. RESULTS AND CONCLUSION:Compared with the normal saline group, the cel density began to increase significantly in three Jianbuhuqian groups at 24 hours after culture, mitotic figures were easy to be observed, cel s were in overlapping growth, much secretions and matrix accumulation appeared, especial y in the high-dose group. The obsorbance values in Jianbuhuqian groups were significantly higher than that in the normal saline group. After 24 hours of culture, the obsorbance values in the medium-dose and high-dose groups were significantly increased compared with the low-dose group, and the values showed significant differences among three Jianbuhuqian groups after 48 and 72-hour culture. In addition, the alkaline phosphatase activity presented overt increase in the Jianbuhuqian groups compared with the normal saline group, and significant differences could be found among Jianbuhuqian groups. To conclude, the drug serum of Jianbuhuqian pil s can promote the activity of osteoblast-like cel s in a time-and concentration-dependent manner.

Objective:To evaluate the safety and feasibility of endovascular recanalization for non-acute internal carotid artery occlusion (NA-ICAO), and to propose a new angiographic classification.Methods:From April 2015 to October 2019, 95 consecutive patients with symptomatic NA-ICAO who received endovascular recanalization were retrospectively analyzed in Beijing Tiantan Hospital, Capital Medical University. All the patients were divided into four groups according to DSA: type Ⅰ, petrous segments were distally reconstituted by collateral vessels; type Ⅱ, cavernous segments were distally reconstituted by collateral vessels; type Ⅲ, ophthalmic segments were distally reconstituted by collateral vessels; type Ⅳ, communicating segments were distally reconstituted by collateral vessels. Study data including clinical characteristics, surgical details, lesion classification, recanalization rate and perioperative complications. For the counting data, the χ 2 test was used to compare between groups. For the quantitative data, the ANOVA was used for the normal distribution data, otherwise the Kruskal-Wallis H test was used. The primary safety outcome was any stroke or death within 30 days. Results:Among the 95 patients, 67 (70.53%) had successful recanalization. The recanalization rates of type Ⅰ－Ⅳ were 92.31% (36/39), 81.82% (18/22), 47.83% (11/23) and 18.18% (2/11) respectively (χ2=29.557, P<0.001). And the complication rates of the four types were 5.13% (2/39), 13.64% (3/22), 21.74% (5/23) and 9.10% (1/11) respectively. The incidence of perioperative ischemic stroke was 2.11% (2/95). No other serious stroke and death occurred. Conclusions:Endovascular recanalization may be feasible and safe for carefully selected patients with NA-ICAO and therefore represents an alternative treatment. The patients with type Ⅰ and Ⅱ lesions had higher recanalization rates, while the patients with type Ⅳ lesions had significantly lower recalculation rate. The new angiographic classification is conducive to the selection of suitable patients and difficulty in grading.

To study pharmacokinetics of injection of iodine-131 labelling MEI-TUO-XI monoclonal antibody (hepatoma monoclonal antibody HAb18 F(ab')2) in vivo. 24 cases of primary hepatocelluar carcinoma (PHC) were equally divided into the low dose group, middle dose group and high dose group. After the relevant injection was administrated into the hepatic artery of each case, intravenous blood and urine samples were separately collected at different time for determination of the radioactive count ratio (min(-1)). The proportion of 131I-HAb18 F(ab')2 in serum of each blood sample was determined, and the radioactive count ratio (min(-1)) of druggery for each blood sample was revised according to the proportion. The pharmacokinetic parameters were calculated using DAS ver 1.0 (Drug And Statistics for Windows) program. The component of urine radiomaterial was determined and the percentages of urine radioactivity in administration dosage were calculated. The catabolism of the injection with time accorded with dynamics two-compartment model. The catabolism product was mainly free-131I and was excreted via kidney; the urine radioactivity was 47.70%-51.16% of administration dosage during 120 h after administration of drug. Therefore, the pharmacokinetics of the injection can satisfy the clinical demands. The drug dose recommended for clinical use was 27.75 MBq of the injection for each kg of human body.

Objective: To investigate the clinical outcomes and radiological results of arthroscopic autologous scapular spine bone graft transplant to treat shoulder recurrent instability. Methods: Data of 27 patients diagnosed as shoulder recurrent instability with the bone defect of 10%-15% from July 2016 to August 2018 who were treated by arthroscopic autologous scapular spine bone graft transplant were retrospectively analyzed. There were 20 males and 7 females with an average age of 30.8 years old (range, 19-50). The bone loss of the glenoid was 10%-15%. The time between the first dislocation and the surgery was 24.1±15.8 months. The patients were treated with arthroscopic autologous scapular spine bone graft transplant. Postoperatively the affected shoulder was immobilized by the abduction brace for 6 weeks, after that the passive motion was applied. Strengthening exercise began at 10-12 weeks and sports was allowed after 6 months. Constant-Murley score and the Disabilities of Arm, Shoulder and Hand (DASH) score were used to evaluate the shoulder function, and visual analogue score (VAS) score was used to evaluate the degree of pain. Computed tomography scans were obtained one week post-operation and at the latest follow-up, from which the length, width, height and volume of the bone graft were measured and the absorption rate of the bone graft was calculated. The subjective satisfaction degree of patients at the latest follow-up was also recorded. Results: All 27 patients were followed up for 19.8 months (range, 13-39 months). No infection or neurovascular injury was identified. At the latest follow-up, the Constant-Murley score was 85.15±5.62 (range, 76-94), the DASH score 13.39±5.51 (range, 3.19-21.95) and the VAS score 1.29±0.45 (range, 1-2), thus all of those were improved significantly compared to those of pre-operation. At the latest follow-up, the anterior flexion was 153°±24°, lateral rotation by side 38°±21°, internal rotation 70°±21°, and abduction was 139°±18°. At the latest follow-up, the absorption rate of the bone graft was 46.1%±20.6% (range, 24.0%-71.7%). Among all the 27 patients, 19 patients considered the outcome as very good, and 6 patients considered as good, 2 patients fair. Conclusion Arthroscopic autologous scapular spine bone graft transplant could successfully treat shoulder recurrent instability with glenoid bone loss at 10%-15%. This technique could achieve satisfactory clinical results, improve glenohumeral stability, decrease the re-dislocation rate.
