【Abstract】Objective To investigate the role of VEGF and its soluble VEGF receptor ( sVEGFR-1) in pathogenesis of acute lung injury ( ALI) induced by immersion in seawater after open chest trauma. Methods Sixteen hybridized adult dogs were randomly divided into control group and seawater group. The control group only suffered from open chest trauma, whereas the seawater group were exposed to seawater after open chest trauma. Blood samples were collected at the 0, 2, 4, 6, 8 h after trauma for measurement of white blood cell count, arterial blood gas, plasma osmotic pressure ( POP) , electrolyte concentration, IL-8, vWF, VEGF and sVEGFR-1 levels. The lungs tissue and BALF was collected at 8 h after trauma. Pathological changes of the lung was observed under light microscope by HE staining. Meanwhile VEGF and sVEGFR-1 levels were measured in BALF and lung tissue homogenate. Total protein concentrations in plasma and BALF were measured to calculate the pulmonary penetration index ( PPI) . Results The lung of the seawater group showed interstitial mononuclear cell and neutrophil infiltration, interstitial edema, and vascular congestion. VEGF and sVEGFR-1 were significantly increased in the plasma, while VEGF was significantly reduced in the lung tissues and BALF. The levels of IL-1β, IL-8 and vWF, just as the level of VEGF, were significantly increased in the plasma. Meanwhile, the POP and electrolyte concentration were significantly increased. In the plasma, the responses of VEGFs during the early onset of ALI induced by immersion in seawater after open chest trauma were consistent with the POP and PPI. Conclusions High plasma levels and low BALF/ lung tissue levels of VEGFs is a distinguishing characteristic during the early onset of ALI induced by immersion in seawater after open chest trauma. VEGF may be a novel biomarker which has an important role in the development of ALI.
ObjectiveTo analyze the related factors of cognitive impairment in patients with post-traumatic epilepsy. MethodsFrom January 2016 to January 2019, 45 patients with post-traumatic epilepsy (epilepsy group) and 48 patients with physical examination (control group) at the Department of Neurosurgery, the 904th Hospital of PLA were analyzed retrospectively. Cognitive assessment were evaluated by the following scales: Montreal cognitive assessment (MoCA), Mini-mental state examination (MMSE), Audio verbal memory test (AVMT), Rey-osterrieth complex figure test (CFT) and Trail making test (TMT). Then we analyzed the influences of gender, age, course of disease, cause, type, degree and location of injury, seizure frequency and Anti-seizure medications (ASMs) on cognitive impairment. ResultsThe results showed that there were significant differences between the epilepsy group and the control group in all scales (P<0.01). Analysis of influencing factors in epilepsy group showed: MoCA and MMSE scores: there were statistical significance in the comparison of seizure frequency and injury degree (P<0.05); AVMT, CFT and TMT scores: there were statistical significance in the comparison of seizure frequency, injury degree and location, ASMs within the group (P<0.05). ConclusionPost-traumatic epilepsy can cause cognitive impairment. The more frequent epileptic seizures and the more severe the degree of trauma, the more serious the cognitive impairment. Different injury sites affect the scope of cognitive impairment, temporal lobe injury is easy to cause memory function decline, frontal lobe injury is easy to cause spatial structure and executive ability decline, at the same time, the combined use of ASMs has an impact on cognitive function.
Objective To explore the change of serum levels of neutrophil gelatinase-associated lipocalin (NGAL), tissue inhibitor of metalloproteinases-2 (TIMP-2), and insulin-like growth factor-binding protein 7 (IGFBP-7) in the early stage of multiple trauma, and their predictive efficacy for acute kidney injury (AKI). Methods The multiple trauma patients admitted between February 2020 and July 2021 were prospectively selected, and they were divided into AKI group and non-AKI group according to whether they developed AKI within 72 h after injury. The serum levels of NGAL, TIMP-2, and IGFBP-7 measured at admission and 12, 24, and 48 h after injury, the Acute Pathophysiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ) score, intensive care unit duration, rate of renal replacement therapy, and 28-day mortality rate were compared between the two groups. Results A total of 51 patients were included, including 20 in the AKI group and 31 in the non-AKI group. The APACHE Ⅱ at admission (20.60±3.57 vs. 11.61±3.44), intensive care unit duration [(16.75±2.71) vs. (11.13±3.41) d], rate of renal replacement therapy (35.0% vs. 0.0%), and 28-day mortality rate (25.0% vs. 3.2%) in the AKI group were higher than those in the non-AKI group (P<0.05). The serum levels of NGAL and IGFBP-7 at admission and 12, 24, and 48 h after injury in the AKI group were all higher than those in the non-AKI group (P<0.05). For the prediction of AKI, the areas under receiver operating characteristic curves and 95% confidence intervals of serum NGAL, TIMP-2 and IGFBP-7 12 h after injury were 0.98 (0.96, 1.00), 0.92 (0.83, 1.00), and 0.87 (0.78, 0.97), respectively. Conclusion Serum NGAL, TIMP-2, and IGFBP-7 have high predictive efficacy for AKI secondary to multiple trauma, and continuous monitoring of serum NGAL can be used for early prediction of AKI secondary to multiple trauma.
Objective To investigate the quality of life (QOL) of Beichuan cadres 1 year after Wenchuan earthquake, so as to provide references for promoting psychological intervention and improving QOL. Methods With the adoption of WHOQOL-BREF, questionnaire survey on basic conditions of cadre victims, and PCL-C scale, cross-section survey was conducted for 2 055 cadres of Beichuan public institutions in aspects of their QOL, social demographic characteristics and psychological trauma. Results a) Compared with domestic norm, although the Beichuan cadres had higher score in social relation domain (14.31 ± 2.59, Plt;0.01), their QOL scores in each dimensions (physical domain score: 14.16 ± 2.43; psychological domain score: 13.79 ± 2.59, environmental domain score: 11.20 ± 2.74) were lower with significant difference (Plt;0.01); b) The group with population under the age of 30 scored higher than other age groups in the psychological and environmental domains; men scored higher than women in the psychological domain; the widowed group scored lower than other groups in all domains; the Han nationality group scored higher than the Qiang nationality group in all domains; the primary education group scored lower than other groups in the social relation domain; the group with relatives, houses and physical loss or damage scored lower than the non-loss group in all domains; and the higher the score in PCL-C, the lower the scores in all domains (all Plt;0.05). Conclusion Beichuan cadres are severely affected in their physical, psychological and environmental domains even one year after Wenchuan earthquake, especially the female, the Qiang nationality, the old, the lost, and the psychological injured cadres are more badly affected with worse QOL, so those population should be concerned in particular with sustainable psychological service and other measures. The finding of social relation domain score being higher than general population suggests that it is important to promote the satisfaction with social relation through the timely effective support from both government and civil society, and the resettlement of sample housing area as well.

Objective To evaluate the mental status of survivors after Wenchuan earthquake, so as to provide relevant information for psychological and medical intervention. Methods Demographic data was recorded and the post-traumatic stress disorder (PTSD) Checklist-Civilian Version (PCL-C) was evaluated. The acute stress disorder (ASD) were assessed with the DSM-IV criteria in the survivors from the central earthquake area who are now living in two shelters in Chengdu. Results Among the 780 retrieved questionnaires, 729 baseline registration forms and 450 PCL-C were valid. In the 729 baseline registration forms, male to female ratio was 1:1.31 and the mean age was 36.73±20.82. 9.5% of subjects suffered from physical diseases, 9.7% needed assistance in daily activities, 70.7% were passive and didn’t participate in community activities, 9.1% suffered from severe psychological problems. In the present study, 30.9% of subjects were found to meet the DSM-IV criteria for ASD. 41.3%, 22.2% and 18.4% of subjects had a PCL-C score ≥ 38, ≥ 45 and ≥50, respectively. Consistency check showed there was no significant difference between the screening result of PCL-C score ≥45 and clinical diagnosis (Kappa=0.780, P=0.033). There was significant difference in the age of subjects between ASD and non-ASD groups (Plt;0.05). Conclusion The earthquake survivors suffered from psychological problems after the disaster in the early stage. Thus, in addition to life rescue, we should pay more attention to psychological intervention.
Objective To explore an effective micro-traumatechnic with small incision for hallux valgus. Methods From August 2002 to June 2004, 136 cases (263 feet) with hallux valgus were treated with micro-trauma technic with small incision and postoperative external elastic fixation. Of all the cases, 7 were males and 129 werefemales. Their ages ranged from 19 to 84 years. According to Coughlin classification, there were 24 gentle cases, 63 medium cases, and 49 severe cases. All the feet were with some degree of pain and flatfoot. Symptom, sign and theresults of X-ray were evaluated.

Hallux valgus of the 263 feet were completely healed, feet pain disappeared, and no nonunion or osteonecrosis was observed. Xray examination indicated that 105 feet’s hallux valgus angle was less than 12°, inter metatarsal angle less than 9°, and remedy subluxation of the tibial sesamoid less than 50%. Evaluation on the result indicated that there were 84 cases of excellent result, 48 cases of good result, 3 cases of fair result, and 1 case of poor result. The rate of excellent and good was 97%. Conclusion With less injury, less pain, complete restoration, and fewer possibility of relapse, microtrauma technic with small incision is effective in treating hallux valgus.
Objective To evaluate the psychological trauma incurred by the hospitalization survivor of Zhouqu district after the Zhouqu debris flow so as to provide relevant information for psychological and medical interventions. Methods The psychological state of 67 hospitalized survivors of the disaster and other 47 inpatients with similar complaints but not coming from the disaster area was investigated through a mental health self-assessment questionnaire, self-rating anxiety scale (SAS), self-rating depression scale (SDS) and PTSD-SS scale. Results The post-disaster survivors had different levels of psychological problems and post-traumatic stress disorder, and there were significant differences compared to the control group (Plt;0.01, Plt;0.01). The SDS score and the SAS score of the survivor were 48.44+15.648 and 52.92+11.672, respectively, which were all much higher than those of the control group (Plt;0.01, Plt;0.05). Conclusion The debris flow disaster bring serious psychological trauma to the victims. It is necessary to pertinently carry out post-disaster psychological relief including psychological intervention and regulation for the hospitalized survivors, so as to alleviate and reduce their psychological suffering.
Objective To analyze the value of serum levels of miR-141-3p, miR-130a, miR-29a-3p, and miR-210 in predicting early neurological deterioration (END) in non-traumatic intracerebral hemorrhage. Methods The patients with non-traumatic cerebral hemorrhage who met the selection criteria and were admitted to Chengde Central Hospital between February 2021 and October 2022 were prospectively selected by convenience sampling method. The serum miR-141-3p, miR-130a, miR-29a-3p, and miR-210 levels upon admission and the occurrence of neurological deterioration within 24 h were collected, and the patients were divided into a deterioration group and a non-deterioration group according to whether neurological deterioration occurred. The correlation of serum miR-141-3p, miR-130a, miR-29a-3p, and miR-210 levels with the END of non-traumatic intracerebral hemorrhage and their predictive value to the END of non-traumatic intracerebral hemorrhage were analyzed. Results A total of 235 patient were enrolled. Of the 235 patients, 45 (19.1%) showed neurological deterioration and 190 (80.9%) showed no neurological deterioration. The levels of miR-141-3p and miR-29a-3p in the deteriorating group were significantly lower than those in the non-deteriorating group [(1.11±0.32) vs. (1.76±0.51) ng/mL, P<0.001; (1.19±0.31) vs. (1.71±0.51) ng/mL, P<0.001], and the levels of miR-130a and miR-210 were significantly higher than those in the non-deteriorating group [(5.13±1.11) vs. (3.82±1.03) ng/mL, P<0.001; (3.96±0.76) vs. (2.78±0.50) ng/mL, P<0.001]. Multivariate logistic regression analysis showed that serum miR-141-3p and miR-29a-3p levels were protective factors for the occurrence of END in non-traumatic intracerebral hemorrhage patients [odds ratio (OR)=0.513, 95% confidence interval (CI) (0.330, 0.798), P=0.003; OR=0.582, 95%CI (0.380, 0.893), P=0.013], and serum miR-130a and miR-210 levels were independent risk factors for that [OR=2.046, 95%CI (1.222, 3.426), P=0.007; OR=2.377, 95%CI (1.219, 4.638), P=0.011]. The area under the receiver operating characteristic curve was 0.857 [95%CI (0.760, 0.954)] in predicting the END of non-traumatic intracerebral hemorrhage by the combined probability of the serum miR-141-3p, miR-130a, miR-29a-3p, and miR-210 levels obtained by logistic regression, and the sensitivity was 86.7%, the specificity was 94.7%, the positive predictive value was 79.6%, and the negative predictive value was 96.8% according to the cut-off value of the prediction probability of the combined test. Conclusion The combined detection of serum miR-141-3p, miR-130a, miR-29a-3p, and miR-210 has a high predictive value in the occurrence of END in non-traumatic intracerebral hemorrhage patients.
Objective To investigate the effectiveness of calcaneal V-shaped osteotomy combined with subtalar arthrodesis in the treatment of Stephens Ⅱand Ⅲ calcaneal fracture malunion. MethodsThe clinical data of 24 patients with severe calcaneal fracture malunion treated by calcaneal V-shaped osteotomy combined with subtalar arthrodesis between January 2017 and December 2021 were retrospectively analyzed. There were 20 males and 4 females with an average age of 42.8 years (range, 33-60 years). Conservative treatment of calcaneal fracture failed in 19 cases and operation failed in 5 cases. Stephens classification of calcaneal fracture malunion was type Ⅱ in 14 cases, and type Ⅲ in 10 cases. Preoperative Böhler angle of calcaneus was 4.0°-13.5° (mean, 8.6°), Gissane angle was 100°-152° (mean, 119.3°). The time from injury to operation was 6-14 months (mean, 9.7 months). American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analogue scale (VAS) score were used to evaluate the effectiveness before operation and at last follow-up. Bone healing was observed and the healing time was recorded. The talocalcaneal height, talus inclination angle, Pitch angle, calcaneal width, and hindfoot alignment angle were measured. Results Necrosis of the cuticle edge of the incision occurred in 3 cases, which were cured by dressing change and oral administration of antibiotic therapy. The other incisions healed by first intention. All the 24 patients were followed up 12-23 months, with an average of 17.1 months. The foot shape of the patients recovered well, the shoes were restored to the size before injury, and there was no anterior ankle impingement. Bone union was achieved in all patients, and the healing time ranged from 12 to 18 weeks, with an average of 14.1 weeks. At last follow-up, no adjacent joint degeneration occurred in all patients; 5 patients had mild foot pain during walking, which had no significant impact on daily life and work; no patient needed revision surgery. The AOFAS ankle and hindfoot score was significantly higher than that before operation (P<0.001), the results were excellent in 16 cases, good in 4 cases, and poor in 4 cases, and the excellent and good rate was 83.3%. The VAS score, talocalcaneal height, talus inclination angle, Pitch angle, calcaneal width, and hindfoot alignment angle were significantly improved after operation (P<0.001). ConclusionCalcaneal V-shaped osteotomy combined with subtalar arthrodesis can effectively relieve hindfoot pain, correct talocalcaneal height, restore talus inclination angle, and reduce the risk of nonunion after subtalar arthrodesis.
