The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.

Objective:To retrospectively compare the clinical efficacy of two PDE3 inhibitors, oplinone and Milrinone, in order to evaluate which drug has better effects on the improvement of cardiac function, protection of renal function and adverse effects of arrhythmia.Methods:A total of 41 neonates with congenital heart disease after biventricular treatment under cardiopulmonary bypass in the Department of Cardiothoracic Surgery at Soochow University Children's Hospital during 2018-2022 were collected. The experimental group was divided into two groups: Oprilinone(25 cases) and Milinone(16 cases). A retrospective study was conducted on the incidence of renal function, cardiac function improvement and arrhythmia in the children.Results:On the first day after operation, EF in both groups decreased significantly compared with that before operation( P<0.01); On day 4 after surgery, EF in the oprilinone group was significantly higher than that on day 1 after surgery( P<0.01), Milrinone group was slightly higher than that on day 1 after surgery( P<0.05), and EF in oprilinone group was significantly higher than that in Milinone group during the same period( P<0.01); EF in Milinone group continued to increase on day 7 compared with day 4( P<0.01), but there was no significant difference between the two groups. Long-term follow-up showed that there was no significant difference in EF value in the oprilinone intervention group on day 7 after surgery( P<0.05), and the long-term EF in Milinone group was higher than that at 7 days after surgery( P<0.05). The creatinine level in the oprinone intervention group continued to decrease on the 4th and 7th day after surgery( P<0.01; P<0.05); The creatinine level of Milinone group on day 4 after surgery was significantly lower than that on day 1 after surgery( P<0.01), the decrease was not significant on the 7th day after surgery compared with the 4th day after surgery; The creatinine level in the oprilinone group was lower than that in the Milrinone group on day 7 after surgery( P<0.05). The rate of arrhythmia in children was slightly decreased in the intervention group of olplinone. There was no change in the Milinone group. Conclusion:Oplinone improved cardiac function better than Milrinone, and the recovery time to normal cardiac function was shorter. In terms of renal function protection, oplinone was stronger than Milrinone, and the protective effect of oplinone on kidney lasted longer. No significant abnormalities were found with respect to adverse reactions, such as the incidence of arrhythmia.

Objective To investigate the predictive value of central venous-to-arterial carbon dioxide difference (Pcv-aCO2) on the prognosis of elderly patients with sepsis.Methods 208 elderly patients who met the diagnostic criteria of the Sepsis-3 and with the age of more than 60 years old, and admitted to intensive care unit (ICU) of Guangdong General Hospital from January to December in 2017 were enrolled. According to the prognosis, the patients were divided into death group (n = 46) and survival group (n = 162). The Pcv-aCO2, central venous oxygen saturation (ScvO2), serum procalcitonin (PCT), C-reactive protein (CRP), sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluationⅡ (APACHEⅡ) were collected for all patients. The differences of each index between the two groups were compared. The correlations between Pcv-aCO2 and ScvO2, PCT, CRP, SOFA, APACHEⅡscores were analyzed respectively with Pearson correlation. The prognostic value of Pcv-aCO2 in elderly patients with sepsis was assessed by receiver operating characteristic curve (ROC).Results Compared with survival group, the Pcv-aCO2, PCT, CRP, SOFA and APACHEⅡscores in death group were significantly increased [Pcv-aCO2 (mmHg, 1 mmHg = 0.133 kPa): 6.13±3.33 vs. 4.40±2.65, PCT (μg/L): 31.41±12.83 vs. 3.01±2.69, CRP (mg/L): 130.51± 42.23 vs. 104.46±50.12, SOFA: 12.01±2.25 vs. 9.05±2.06, APACHEⅡ: 29.52±5.03 vs. 20.01±3.21, allP < 0.05], and ScvO2 in death group was significantly decreased (0.571±0.136 vs. 0.685±0.106,P < 0.01). Correlation analysis showed that the Pcv-aCO2 was negatively correlated with ScvO2 (r = -0.762,P = 0.001) and was positively correlated with PCT, CRP, SOFA and APACHEⅡscores (r value was 0.737, 0.625, 0.738, 0.713, respectively, allP < 0.05). ROC curve analysis showed that the area under the ROC curve (AUC) of Pcv-aCO2 prediction of death in patients with sepsis was 0.826, the cut-off was 6.62 mmHg, the sensitivity was 84.7％, the specificity was 77.5％, the positive likelihood ratio was 3.76, and the negative likelihood ratio was 0.19.Conclusion Pcv-aCO2 has a great value in evaluating the prognosis of elderly patients with sepsis and can accurately determine the prognosis of sepsis.

OBJECTIVE:To investigate risk factors of multidrug-resistant organisms (MDROs) infection in elderly patients of ICU,and to provide reference for formulation and implementation of MDROs prevention and control measures.METHODS:A total of 146 elderly patients were selected from ICU of our hospital during Dec.2013-Jun.2016.Throat swab,sputum swab and anal swab specimens (1 copy,respectively) were collected to conduct active screening of MRSA and ESBLs-producing Enterobacteriaceae.Risk factors of MDROs infection,pathogen distribution and drug resistance were analyzed.RESULTS:Among samples of 146 patients,there were 34 MRSA positive samples in throat swab with positive rate of 23.3％;there were 30 MRSA positive samples in sputum swab with positive rate of 20.5％;there were 99 ESBLs-producing bacteria positive samples in anal swab (containing 50 ESBLs-producing Escherichia coli positive samples and 49 ESBLs-producing Klebsiella pneumoniae positive samples) with positive rate of 67.8％.The positive rate of throat swab MRSA screening was not correlated with patient's gender,age,tracheal intubation or mechanical ventilation (P＞0.05),but it was related with hospitalization time in ICU (P＜0.05).The positive rate of sputum swab MRSA screening was not correlated with patient' s gender,tracheal intubation or mechanical ventilation;the positive rate of anal swab ESBLs-producing bacteria screening were not related with patient's gender(P＞0.05).But they were related with age and hospitalization time in ICU (P＜0.05).Compared with negative patients,there was no statistical significance in the times of fiberoptic bronchoscopy in throat/sputum swab MRSA screening positive patients (P＞0.05).The times of enema,the times of bladder irrigation,the times of urethral catheterization and the duration of indwelling catheter in anal swab ESBLs-producing bacteria screening positive patients were significantly more or longer than negative patients,with statistical significance (P＜0.05).Binary Logistic regression analysis showed that hospitalization time in ICU was risk factor of positive active screening of throat swab in elderly patients of ICU[OR=1.119,95 ％ CI (1.071,1.385),P=0.021];age was risk factor of positive active screening of sputum swab[OR=1.893,95 ％ CI (1.232,4.042),P=0.032];age and hospitalization time in ICU were risk factors of positive active screening of anal swab [OR were 1.046,1.022,95％CI were (1.005,1.088) (1.006,3.283),P were 0.027,0.031].A total of 163 strains of MDROs were detected,among which there were 64 strains of MRSA,50 strains of ESBLs-producing E.coli and 49 strains of ESBLs-producing K.pneumoniae.They were generally highly resistant to compound preparation containing enzyme inhibitors.CONCLUSIONS:The results of MDROs active screening in elderly patients of ICU are related with age,hospitalization time in ICU,the times of enema,the times of bladder irrigation,the times of urethral catheterization and the duration of indwelling catheter.Age and hospitalization time in ICU were risk factors of MDROs infection.The pathogens are mainly ESBLs-producing Enterobacteriaceae,and drug resistance is severe.For elderly critical patients with MDROs infection,clinical prevention and intervention measures should be taken to prevent and control the prevalence and spread of MDROs in ICU.

OBJECTIVE:To observe the effects of Alprostadil dried emulsion for injection combined with Butylphthalide soft capsules on nerve function,inflammatory factor and coagulation function of patients with severe ischemic stroke. METHODS:A total of 66 patients with severe ischemic stroke selected from our hospital during Jun. 2015-Oct. 2017 were divided into control group and observation group according to random number table,with 33 cases in each group. On the basis of routine treatment, control group was additionally given Butyphthalide soft capsules 0.2 g/time,orally at fasting state,tid. On the basis of control group,observation group was additionally given Alprostadil dried emulsion for injection 10 μg added into 0.9% Sodium chloride injection 10 mL,via slow infusion or slow dripping with pipkin,qd. Both groups were treated for 14 days. NIHSS and Barthel index scores,the levels of serum inflammatory factors(CRP,PCT)and coagulation function indexes(D-D,TT,PT,APTT, FIB)were observed in 2 groups before and after treatment,and the occurrence of ADR was also recorded. RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups(P>0.05).After treatment,NIHSS scores,the levels of CRP,PCT,D-D and FIB in 2 groups were deceased significantly,while Barthel index scores were increased significantly,TT,PT,APTT were prolonged significantly;observation group was significantly better than control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Alprostadil dried emulsion for injection combined with Butylphthalide soft capsules can effectively improve nerve function and coagulation function of patients with severe ischemic stroke,and reduce the levels of inflammatory factor with good safety.
