ABSTRACT
Objective:To investigate the relationship between blood pressure variability (BPV) and incidence of post-traumatic stress disorder (PTSD) in trauma patients.Methods:Patients admitted to the department of emergency medicine of the Affiliated Hospital of Xuzhou Medical University for acute trauma from January 2018 to December 2021 were enrolled. The clinical data and blood pressure at admission (T1), 10 minutes before anesthesia (T2), 60 minutes after surgery (T3), and 24 hours after surgery (T4) were collected. Coefficient of variation of blood pressure variation [CV-BP, including coefficient of variation of systolic blood pressure (CV-SBP), coefficient of variation of diastolic blood pressure (CV-DBP), coefficient of variation of mean arterial pressure (CV-MAP)] and its quartile were calculated. Patients were divided into Q1 group (CV-MAP ≤ 7.27), Q2 group (7.27 < CV-MAP ≤ 9.50), Q3 group (9.50 < CV-MAP ≤ 14.05) and Q4 group (CV-MAP > 14.05) according to CV-MAP quartile. The PTSD symptoms of the patients were evaluated using the PTSD scale (PCL-5) one month later, and the patients were divided into the PTSD group and the non-PTSD group according to whether PCL-5 score higher than 38. Then the differences of the above indicators were compared and analyzed. Spearman correlation analysis was used to analyze the relationship between each index and PCL-5 score; the risk factors of PTSD were analyzed by univariate binary Logistic regression. Variables with P < 0.05 were included in the multivariate binary Logistic regression model. The receiver operator characteristic curve (ROC curve) was drawn to analyze the predictive value of CV-MAP on the incidence of PTSD. Results:A total of 112 patients were enrolled, including 24 in PTSD group and 88 in non-PTSD group. Compared with non-PTSD group, the proportion of women, T1 shock index, proportion of intraoperative and postoperative blood transfusion in PTSD group was higher. Besides, PTSD group also had longer PT, more intraoperative and postoperative blood transfusion, and lower postoperative hemoglobin (Hb) level (all P < 0.05). The T1 SBP, DBP, MAP and T4 MAP of patients in PTSD group were significantly lower than those in non-PTSD group [T1 SBP (mmHg, 1 mmHg≈0.133 kPa): 105.0 (86.3, 121.3) vs. 122.0 (112.0, 132.8), T1 DBP (mmHg): 62.5 (50.0, 77.3) vs. 76.0 (68.5, 82.8), T1 MAP (mmHg): 77.8 (60.4, 91.3) vs. 93.3 (82.5, 99.0), T4 MAP (mmHg): 83.8±9.1 vs. 88.7±10.4, all P < 0.05], CV-SBP, CV-DBP and CV-MAP were higher than those in the non-PTSD group [CV-SBP: 12.80 (10.12, 19.16) vs. 9.30 (6.07, 12.95), CV-DBP: 16.62±6.47 vs. 12.40±5.61, CV-MAP: 14.10 (9.25, 18.85) vs. 8.90 (6.93, 13.29), all P < 0.05]. Spearman correlation analysis showed that there was a positive correlation between CV-MAP and PCL-5 scores in patients with acute trauma ( r = 0.429, P < 0.001); multivariate binary Logistic regression analysis showed that only CV-MAP [odds ratio ( OR) = 1.128, 95% confidence interval (95% CI) was 1.015-1.254, P = 0.025] and CV-DBP ( OR = 1.114, 95% confidence interval (95% CI) was 1.016-1.221, P = 0.022) was the risk factor for PTSD in acute trauma patients. Compared with Q1 group, Q4 group was significantly more likely to develop PTSD ( OR = 18.6, 95% CI was 1.9-179.1, P = 0.012). CV-SBP, CV-DBP and CV-MAP had certain predictive value on PTSD diagnosis in patients with acute trauma according to ROC curve analysis results [area under the ROC curve (AUC) was 0.713, 0.682 and 0.726, respectively], among which CV-MAP has the highest predictive value. When the cut-off value of CV-MAP was 12.158, the sensitivity was 75.0% and the specificity was 69.3%. Conclusion:Higher BPV after trauma is a risk factor for PTSD. Maintaining stable blood pressure in trauma patients is of great significance for prevention and treatment of PTSD.
ABSTRACT
Standardized cardiopulmonary resuscitation (CPR) of patients prior to the arrival of emergency medical services can significantly improve survival rate after out-of-hospital cardiac arrest (OHCA). According to statistics, about 40% to 85% of CPR led to chest fractures, making bystanders alarm, and reducing the willingness of rescuing by CPR. Therefore, there is an urgent need to develop a CPR protection device that is convenient for placing in public places outside the hospital and conforms to the operation habit of freehand CPR. In view of the above problems, medical students majored in emergency and rescue medicine and anesthesiology in Xuzhou Medical University, together with students majored in product design in Southeast University, designed a portable CPR protection device under the guidance of doctors working in department of emergency medicine of the Affiliated Hospital of Xuzhou Medical University, and obtained the national invention patent authorization of China (patent number: ZL 2021 1 0309001.4) and the national utility model patent authorization of China (patent number: ZL 2021 2 0591084.6). The device is composed of a foldable frame, support components, guide slide rails and compression body, which provides guidance and guarantee for the implementation of CPR, thus users can accurately grasp the implementation process, compression amplitude, strength and frequency, and effectively prevent accidental injuries such as rib fractures caused by CPR compression. The device is small, easy to store and move, with low manufacturing cost, making it suitable for social popularization.
ABSTRACT
Objective:To compare the value of difference between thromboelastogram (TEG), coagulation function and mean platelet volume (MPV)/platelet count (PLT) ratio in sepsis patients with short-term prognosis.Methods:A total of 271 patients with sepsis admitted to the Affiliated Hospital of Xuzhou Medical University from January 2020 to September 2021 were retrospectively analyzed. The clinical data of the patients were recorded, and the SOFA score and APACHE Ⅱ score were calculated. The patients were followed up within 28 days and were divided into the survival group and death group. The TEG, coagulation function and MPV/PLT ratio were compared between the two groups. The independent prognostic factors of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were confirmed by Logistic regression analysis. The combination of Angle + CI + AT-Ⅲ + D-Di +MPV/PLT ratio was established, and the ROC curve was drawn to evaluate the prognostic value of Angle, CI, AT-Ⅲ and D-Di combined with MPV/PLT ratio in patients with sepsis.Results:The mortality rate of patients with sepsis was 42.4%. The D-Di and MPV/PLT ratio of the death group were significantly higher than those of the survival group, and the differences were statistically significant. Angle, CI and AT-III in the death group were significantly lower than those in the survival group, and the differences were statistically significant. Logistic regression analysis showed that Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were independent predictors of the prognosis of patients with sepsis (all P < 0.05) . The area under the curve of the combined detection of Angle, CI, AT-Ⅲ, D-DI and MPV/PLT ratio to evaluate the prognosis of sepsis at 28 days was 0.931, which was larger than that of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio alone (0.755, 0.790, 0.776, 0.729 and 0.746). The sensitivity and specificity of the combination of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio were 83.5% and 91.0%, which were also higher than those of the single index . Conclusions:Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio are independent prognostic predictors of patients with sepsis. The combination of Angle, CI, AT-Ⅲ, D-Di and MPV/PLT ratio has high sensitivity and specificity in evaluating the prognosis of sepsis.
ABSTRACT
Objective:To investigate the predicting value of high sensitivity C-reactive protein (hs-CRP) and albumin (Alb) ratio on prognosis of patients with in-hospital cardiac arrest (IHCA).Methods:A total of 107 patients with IHCA and spontaneous circulation recovery (ROSC) after cardiopulmonary resuscitation (CPR) in the Affiliated Hospital of Xuzhou Medical University during January 1, 2017 and September 30, 2020 were selected as the subjects and divided into the survival group and death group according to the survival condition on day 14 after IHCA. The correlation between ratio of high sensitivity C-reactive protein/albumin (hs-CRP/Alb) and the prognosis of patients was analyzed.Results:No statistical significant differences were found between the survival and death groups in sex, age, medical history, ECG monitoring, recovery ventilation mode, percentage of first monitoring of heart rate and pre-resuscitation Alb (all P > 0.05). However, there were significant differences in the percentage of non-cardiogenic CA and adrenaline dose > 5 mg, time of CPR, concentrations of blood lactic acid, Alb, hs-CRP, and ratio of hs-CRP/Alb (all P < 0.05). Logistic regression analysis showed that percentage of adrenaline dose > 5 mg, concentration of blood lactic acid, time of CPR, and ratio of hs-CRP/Alb were independent risk factors for predicting death. ROC curve analysis showed that hs-CRP/Alb ratio, and concentration of hs-CRP and Alb had predictive value on the death of patients with IHCA; the areas under the curves of hs-CRP/Alb ratio, hs-CRP and Alb concentration were 0.876, 0.864 and 0.745, respectively. The predictive efficiency of hs-CRP/Alb ratio was better than that of hs-CRP concentration or Alb concentration. Conclusions:hs-CRP/Alb ratio has predictive value for the prognosis of patients with IHCA and the predictive value is superior to that of hs-CRP and Alb concentration.
ABSTRACT
Objective:To investigate the relationship between the changes in inflammatory markers levels and the onset of post-traumatic stress disorder (PTSD) in the early stage of acute trauma..Methods:From January 2018 to June 2020, patients with acute trauma who were admitted to the Affiliated Hospital of Xuzhou Medical University were selected as subjects. Peripheral venous blood was collected on admission, on the 3rd and 7th day after trauma for routine blood test, C-reactive protein (CRP) and procalcitonin (PCT). The neutrophil to lymphocyte ratio (NLR) was calculated. The PCL-5 scale was used to evaluate PTSD symptoms one month later. The patients were divided into the PTSD group and non-PTSD group with the score of 38 as the boundary. The change rule of NLR in the PTSD group and the non-PTSD group were analyzed.Results:Ninety-one trauma patients were enrolled, including 23 patients in the PTSD group and 68 patients in the non-PTSD group. Compared with the healthy control group, the NLR of 91 trauma patients on admission, on the 3rd and 7th day were significantly higher (all P< 0.01). The NLR of the PTSD group was increased on the 7th day after trauma, which was significantly higher than that of the non-PTSD group ( P= 0.025). The non-PTSD group showed a decreasing trend, of which NLR on the 7th day was significantly lower than that on admission ( P= 0.001). In addition, high level of NLR on the 7th day after trauma (β= 0.206, P= 0.01) was a risk factor for PTSD onset. Conclusions:Dynamic monitoring of the changes in NLR after acute trauma would be of great clinical value to early warning of PTSD.
ABSTRACT
Objective:To explore the influence of intensive analgesia on the incidence of post-traumatic stress disorder (PTSD) in acute trauma patients, and to develop new ideas for the prevention and treatment of PTSD.Methods:From January 2018 to November 2019, a prospective study was conducted on trauma patients who visited the Emergency Center of Affiliated Hospital of Xuzhou Medical University and met the enrollment criteria. The patients were divided into the intensive analgesia group (< 4) and non-intensive analgesia group (≥ 4) according to the mean pain score in 30 days. The epidemiological data, trauma-related parameters, analgesic schemes, VAS score, PCL-5 score, HADS score and incidence of PTSD of enrolled patients were collected. Appropriate statistical methods were used to analyze differences among the indicators between the two groups.Results:Eighty-four acute trauma cases were included in the study, 39 cases in the intensive analgesia group and 45 in the non-intensive analgesia group. There was no significant difference in baseline data between the two groups (all P>0.05). The incidence rate of PTSD and PCL-5 score of patients in the intensive analgesia group were all significantly lower than those in the non-intensive analgesia group in 1 month after the trauma (all P< 0.05). The HADS anxiety and depression scores of patients in the intensive analgesic group were significantly lower than those in the non-intensive analgesic group (all P< 0.05). All the analgesics were converted into the dosage of dezocine for comparison. The total dosage of analgesics (dezocine) used in patients of the intensive analgesia group was significantly higher than that in the non-intensive analgesia group within 30 days after injury ( P< 0.05). Conclusion:In the acute trauma patients, intensive analgesia after trauma can significantly reduce the incidence of PTSD as well as improve anxiety and depression symptoms.
ABSTRACT
Objective:To investigate the effect of post-traumatic pain on post-traumatic stress disorder (PTSD).Methods:A prospective trial was conducted with the recruitment of patients referred to the Emergency Center of Affiliated Hospital of Xuzhou Medical University for acute trauma from January 2018 to June 2019, with the exclusion criteria: age < 18 years, severe eye injury, severe craniocerebral injury and other critical conditions. The clinical data and written informed consent were collected at admission, the post-traumatic pain was assessed by VAS scores and the trauma severity was assessed by ISS score. APACHEⅡ score were evaluated within 24 h after admission. One month after trauma, patients with history of mental illness, or history of major psychogenic trauma within one year or drug addiction were further excluded. Accordingly, 64 eligible patients were evaluated by VAS, and the PCL-5 scale was used to evaluated their PTSD symptoms. The patients were divided into the PTSD group and non-PTSD group according to PCL-5 score≥ 38, and the difference between the two groups in post-traumatic VAS scores was compared. Logistic regression analysis was used to analyze the risk factors of PTSD. Spearman correlation analysis was adopted to establish the correlation between VAS score at admission and PCL-5 score at one month after trauma. The receiver operator characteristic (ROC) curve was used to analyze the predictive value of traumatic pain intensity for PTSD onset.Results:Sixty-four patients were selected and defined as the PTSD group ( n=19) and non-PTSD group ( n=45). The VAS score at admission was significantly higher in the PTSD group than that in the non-PTSD group ( P=0.006). There was no significant difference in VAS scores and VAS variations at 1 month, and in ISS scores at admission and APACHEⅡ scores within 24 h after admission between the two groups. Traumatic pain was an independent risk factor for PTSD ( P=0.043). VAS score at admission was positively correlated with PCL-5 score at 1 month post-traumatically ( r=0.355, P=0.004). In addition, ROC curve analysis showed that VAS score > 8 at admission had predictive value for PTSD (sensitivity=100%, specificity=33%, P=0.000 2). Conclusions:Post-traumatic severe pain is an independent risk factor for PTSD, which requires prompt medical intervention.
ABSTRACT
Objective To investigate the therapeutic effect of oxiracetam combined with dexamethasone for treatment of patients with severe acute carbon monoxide poisoning (ACOP).Methods Eighty-seven patients with severe ACOP admitted to Affiliated Hospital of Xuzhou Medical University from January 2013 to July 2016 were enrolled, and they were divided into observation group (47 cases) and control group (30 cases) according to random number table method. The two groups were given conventional nerve nutrition, hyperbaric oxygen and symptomatic treatment, while in the observationgroup, on the basis of conventional treatment the patients received intravenous drip of dexamethasone 5 mg (with addition of normal saline 100 mL), once a day for consecutive 3 days, and intravenous drip of oxiracetam 3.0 g plus 100 mL normal saline, once a day for consecutive 7 days. The changes of mini-mental state examination (MMSE), Barthel index and Glasgow coma scale (GCS) were observed after discharge for 30 days, and the differences of the incidence of delayed encephalopathy after acute carbon monoxide poisoning (DEACMP) and hospitalization time between the two groups were compared.Results After treatment the MMSE and GCS scores of the two groups were higher than those before treatment, and the Barthel score was lower than that before onset. After discharge for 30 days, MMSE score (26.93±2.92 vs. 24.20±6.82), GCS (14.41±1.32 vs. 13.98±2.13), Barthel (94.78±12.62 vs. 85.25±19.57) of the observation group were significantly higher than those of control group, and the incidence of DEACMP was obviously lower than that in the control group [8.5% (4/47) to 17.5% (7/40)], the differences between the two groups being statistically significant (allP 0.05).Conclusion Early combined application of oxiracetam and dexamethasone can significantly improve the cognition and self-care abilities and reduce the incidence of DEACMP in patients with severe ACOP after discharge for 30 days.
ABSTRACT
Objective o investigate the prophylactic and therapeutic effects of montelukast,a cysteinyl leukotriene receptor-1 (CysLT1R) antagonist,on the delayed neuropsychological sequelae (DNS) in rat model of carbon monoxide (CO) poisoning and to explore the possible underlying mechanism.Methods A total of 90 rats were acclimated for one week prior to screening rat by Morris water maze test.Ten rats were randomly assigned to control group (Con group),and the remaining 80 rats were subjected to modified method of intraperitoneal injection of CO gas to establish animal model of acute CO poisoning,Thereafter,the survival rats randomized into CO poisoning group (Mod group),low-dose montelukast group (ML group),medium-dose montelukast group (MM group),high-dose montelukast group (MH group) (n =10 each).Montelukast was accordingly administered via intragastric tube at different intervals (30 min,4 h and 12 h) after CO poisoning,and then montelukast was administered every 12 hours for 7 consecutive days.The rats of control group and Mod group received equal volume of normal saline instead at given intervals.Twenty-one days after CO exposure,the average escape latency was measured by Morris water maze test to screen DNS rats followed by H-E staining to observe the pathological changes of cortex and hippocampal CA1 region and TUNEL was used to assess the apoptosis of neurons in cortex and hippocampal CA1 region after rats sacrificed.Results All CO-exposed rats exhibited cognition function lowered,and the escape latency (seconds) in Mod group (43.3 ± 15.5),ML group (31.5 ± 13.2) and MH groups (30.1 ± 12.2) was significantly prolonged compared with Con group (12.1 ± 3.0) (P ＜ 0.05),whereas the difference between MM group (15.0 ± 6.6) and Con group was statistically insignificant (P ＞ 0.05).Compared with Mod group,the escape latency in montelukast treatment groups was shortened,whereas the significant difference in escape latency only found between Mod group and MM group (P ＜ 0.05).Except for Con group,DNS was evident in CO-exposed groups,and the numbers of DNS rats in Mod,ML,MM and MH groups were 8,5,1,4,respectively,which made statistically significant differences to Con group (P ＜ 0.05) except MM group.The DNS incidence in MM group was lower than that in Mod group (P ＜ 0.05).Mod group exhibited severe histopathological injury to the brain,with evident apoptosis of neural cells,whereas in the groups with montelukast treatment,histopathological damage to the brain was mitigated and the number of apoptotic neuronal cells was diminished noticeably in MM group.Conclusion Montelukast can ameliorate the cognitive function of rats,decrease the incidence of DNS and reduce the apoptosis of neural cells as well as attenuate neuronal cell injury,thus exerting neuroprotection against DNS in rats with CO poisoning.
ABSTRACT
OBJECTIVE:To explore therapeutic efficacy and safety of Puerarin injection for elderly female patients with osteo-porosis and unstable angina pectoris,and its effects on serum inflammatory factors. METHODS:Totally 107 elderly women with osteoporosis and unstable angina were analyzed retrospectively and divided into control group(53 cases)and observation group(54 cases) according to drug use. Control group was given routine treatment as Caltrate D,Alendronate sodium tablet,Glyceryl trini-trate tablet ,Metoprolol tartrate tablet,Atorvastatin calcium tablet,Trimetazidine hydrochloride tablet. On the basis of control group, observation group was additionally given Puerarin injection 4 mL added into 5% Glucose injection 500 mL intravenously,once a day. Treatment course of 2 groups lasted for 2 weeks. Therapeutic efficacies of 2 groups were observed as well as the levels of se-rum inflammatory factors(hs-CRP,TNF-α,MMP-9,sCD40L),and the occurrence of ADR. RESULTS:The total response rates of angina pectoris and osteoporosis pain in observation group were significantly higher than control group,with statistical signifi-cance (P0.05). After treatment,the levels of hs-CRP,TNF-α,MMP-9 and sCD40L in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical sig-nificance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Based on routine treatment,Pu-erarin injection shows significant therapeutic efficacy for senile female osteoporosis patients with unstable angina and can significant-ly reduce the levels of serum inflammatory factors with good safety.
ABSTRACT
Objective To investigate the role and potential mechanism of interleukin-17A (IL-17A) in the inflammatory response to traumatic brain injury (TBI) in rats.Methods The adult male Wistar rats were randomly (random number) divided into seven groups:control group (n =6),sham operation group (n =6),TBI group (n =24),sham operation + normal saline group (n =6),sham operation + Y320 (an immunomodulator acts as an inhibitor of IL-17A) group (n =6),TBI + normal saline group (n =6) and TBI + Y320 group (n =6).The TBI model of rat was established by using free-falling-body impact device.The levels of IL-17A and nuclear transcription factor kappa B p65 (NF-κB p65) in the cerebral cortex were assayed by using Western Blot.The capability of leaming and memory of rats was assessed by Morris water maze.The beam balance test was employed to evaluating the neurological motor performance and the capability of balance.Results Compared with the sham operation group,the levels of IL-17A and NF-κB p65 in the cerebral cortex of TBI,TBI + saline and TBI + Y320 groups increased significantly (P ＜0.05) and peaked at the 3rd day after TBI.Compared with TBI + normal saline group,the level of NF-κB p65 was significantly down regulated by Y-320 (P ＜ 0.05) at the 3rd day after TBI in TBI + Y320 group.The lengths of latency time required for rats to escape to the platform area in TBI + normal saline group were (57.72±3.29) s,(55.63±3.85) s,and (55.02±3.92) sat the3rd,5th and7th days after TBI,respectively;while those in TBI + Y320 group were (35.45 ± 3.04) s,(30.98 ± 2.92) s,and (23.90 ±2.51) s at the 3rd,5th and 7th days after TBI,respectively.Thus,the capability of learning and memory of rats in TBI + Y320 group was improved significantly 3d,5d and 7 days after TBI (all P ＜ 0.01).Conclusions This study shows IL-17A is involved in the process of secondary brain injury after TBI,and associated with inflammation by activating the NF-κB p65 signaling pathway.
ABSTRACT
<p><b>BACKGROUND</b>Neutrophil/lymphocyte ratio (NLR) has been proposed as a novel marker of systemic inflammation and oxidative stress. The objective of this study was to ascertain the relationship between levels of NLR and recurrence of lone atrial fibrillation (AF) after catheter ablation.</p><p><b>METHODS</b>A total of 379 lone AF patients who underwent catheter ablation were enrolled in the study. The NLR before and after catheter ablation was determined. Cox regression analyses were used to estimate the relationship between NLR and the recurrence of lone AF.</p><p><b>RESULTS</b>After a mean follow-up of (30.5 ± 5.3) months, 124 (32.7%) patients had AF recurrences. The patients who developed AF recurrence had a higher postablation NLR (post-NLR) than patients with no recurrence (5.74 ± 1.55 vs. 4.66 ± 1.27, P < 0.001). Multivariate Cox regression analysis revealed that post-NLR (hazard ratio (HR) 1.514, 95% confidence interval (CI) 1.364-1.680, P < 0.001), left atrium diameter (HR 1.035, 95% CI 1.001-1.071, P = 0.04) and body mass index (HR 1.028, 95% CI 1.002-1.054, P = 0.03) were independent predictors of AF recurrence. Using a cut-off level of 5.15, post-NLR predicted AF recurrence with a sensitivity of 73% and specificity of 67%.</p><p><b>CONCLUSIONS</b>Our results indicate that an elevated post-NLR is associated with a high rate of lone AF recurrence. A simple measurement of NLR may help us to identify high-risk patients who need pharmacologic intervention to prevent recurrence.</p>
