Objective:To observe the effect of theophylline intravenous drip combined with high flow respiratory humidifier on serum pro Calcitonin (PCT) and lactate clearance rate (LCR) in elderly patients with chronic obstructive pulmonary disease (COPD) secondary to type II respiratory failure.Methods:We prospectively selected 120 elderly patients with COPD secondary to type II respiratory failure who were admitted to the Affiliated Hospital of Jining Medical University from March 2020 to March 2022. They were randomly divided into the control group ( n=60) and the observation group ( n=60). The control group was treated with non-invasive positive pressure ventilation combined with theophylline intravenous drip, and the observation group was treated with high flow respiratory humidification therapy apparatus combined with theophylline intravenous drip. The sputum viscosity of the two groups was counted, and the pulmonary function [forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1), FEV 1/FVC], blood gas analysis, respiratory mechanics, oxygen metabolism, and serum index levels, as well as the difference between acute physiology and chronic health assessment Ⅱ (APACHE Ⅱ) scores after treatment were compared between the two groups. Results:The overall sputum viscosity of the observation group was better than that of the control group ( P<0.05). Before treatment, there was no statistically significant difference in lung function and blood gas analysis indicators between the two groups (all P>0.05); After treatment, the lung function indicators, arterial partial pressure of oxygen (PaO 2), and oxygenation index (PaO 2/FiO 2) of both groups were significantly increased compared to before treatment (all P<0.05), while arterial partial pressure of carbon dioxide (PaCO 2) was significantly decreased compared to before treatment (all P<0.05), and the values of each indicator in the observation group after increasing or decreasing were significantly better than those in the control group (all P<0.05). Before treatment, there was no statistically significant difference in respiratory mechanics and oxygen metabolism indicators between the two groups (all P>0.05); After treatment, the arterial blood oxygen content (CaO 2) in the two groups was significantly higher than that before treatment (all P<0.05), while the oxygen uptake rate (ERO 2) in the two groups and the VO 2 max (VO 2Max), airway peak value, and respiratory resistance in the observation group were significantly lower than those before treatment (all P<0.05), and the values of each index in the observation group after rising or falling were significantly better than those in the control group (all P<0.05). Before treatment, there was no statistically significant difference in serum indicators and APACHE Ⅱ scores between the two groups (all P>0.05); After treatment, LCR and C-reactive protein (CRP) in the observation group were significantly higher than those before treatment ( P<0.05), while the scores of PCT, Interleukin 6 (IL-6), CRP and APACHE Ⅱ were significantly lower than those before treatment (all P<0.05), and the values of each index in the observation group after increase or decrease were significantly better than those in the control group (all P<0.05). Conclusions:Theophylline intravenous drip combined with high flow respiratory humidifier can improve respiratory mechanics, oxygen metabolism, reduce inflammatory reaction, and reduce the impact of disease on life in elderly patients with COPD secondary to type II Respiratory failure.

Objective:To investigate the value of multi-slice spiral CT (MSCT) combined with three myocardial markers in the diagnosis of acute chest pain etiology.Methods:A retrospective study was conducted on 120 patients with acute chest pain admitted to the Affiliated Hospital of Jining Medical University from January 2020 to December 2020. All patients underwent MSCT imaging examination upon admission, and serum creatine kinase isoenzyme MB (CK-MB), troponin I (cTnI), and myoglobin (MYO) levels were also tested. The final clinical diagnosis was used as the judgment standard to draw a 2×2 four-square table, and calculate the value of MSCT, CK-MB, cTnI, and MYO in the diagnosis of acute chest pain etiology.Resultsl:Among the 120 acute chest pain patients included, 75 were diagnosed with acute coronary syndrome (62.50%), 16 with aortic dissection (13.33%), and 29 with pulmonary embolism (24.17%). The coincidence rate of MSCT diagnosis of coronary heart disease was 86.67%(65/75), the diagnosis of aortic dissection coincidence rate was 12/16, and the diagnosis of pulmonary embolism coincidence rate was 75.86%(22/29). The serum CK-MB, cTnI, and MYO levels in the coronary heart disease group were significantly higher than those in the aortic dissection group and pulmonary embolism group, and the differences were statistically significant (all P<0.05). There was no significant difference in serum CK-MB, cTnI, and MYO levels between the aortic dissection group and pulmonary embolism group (all P>0.05). The sensitivity of CK-MB, cTnI, and MYO in the differential diagnosis of acute chest pain patients with coronary heart disease and non-coronary heart disease were 93.33%, 85.33%, and 89.33%, respectively, and the specificity were 73.33%, 80.00%, and 77.78%, respectively. The areas under the receiver operating characteristic (ROC) curve were 0.833, 0.826, and 0.836, respectively. Conclusions:MSCT can better identify coronary heart disease, aortic dissection, and pulmonary embolism in patients with acute chest pain, while the three myocardial markers can better distinguish patients with coronary heart disease and non-coronary heart disease. Therefore, MSCT combined with myocardial markers should be used for the diagnosis of acute chest pain patients in clinical practice to facilitate early clinical diagnosis.

Objective:To analyze the plasma levels of soluble immune checkpoint molecules in patients with primary liver cancer and their prognostic significance.Methods:The levels of sCD28, sCD80, sCD137, sCD27, sGITR, sTIM3, sCTLA4, sHVEM, IDO, sLAG3, sBTLA, sPD1, sPDL1 and sPDL2 in plasma samples of 58 patients with primary liver cancer and 30 healthy controls were detected by liquid chip technology and compared between different groups. The relationship between the plasma levels of soluble immune checkpoint molecules and tumor recurrence was analyzed.Results:The levels of sCD28 and sCD80 were higher in patients in Barcelona Clinic Liver Cancer (BCLC) stage 0/A and B than in healthy controls and patients in BCLC-C stage ( P<0.05). However, the levels of sCD27 and sHVEM in BCLC-C patients were significantly lower than those in BCLC-0/A and BCLC-B patients, and even lower than healthy control group. The levels of sCD137, IDO and sPD1 in BCLC-0/A and BCLC-B patients were higher than those in healthy controls. The levels of sPDL1 and sPDL2 in different BCLC stages were all higher than those in healthy controls, and maintained at high level in the three stages, but there was no significant difference between different stages. After 24 months of interventional treatment, the preoperative sCD28 level was lower in patients with recurrent tumor recurrence than in patients without recurrence ( t=2.843, P=0.007). The optimal cut-off value of sCD28 based on the receiver operating characteristic (ROC) curve for predicting tumor recurrence was 101.42 pg/ml and the area under the ROC curve was 0.771 (95%CI: 0.611-0.931) with a sensitivity of 0.889 and a specificity of 0.666. The cumulative recurrence rate in patients with high sCD28 level (≥101.41 pg/ml) was 57.9% at 24 months after surgery, which was lower than the rate (95.5%) in patients with low sCD28 level (<101.41 pg/ml). The difference in the cumulative recurrence rate between the two groups was statistically significant (χ 2=15.777, P=0.000). Conclusions:The expression patterns of soluble immune checkpoint molecules varied in patients at different stages of primary liver cancer, suggesting that there were differences in their immune status and sCD28 could be used as a prognostic marker for postoperative recurrence of liver cancer.

Objective:To investigate the effect of intraoperative blood transfusion on postoperative deep vein thrombosis in patients with orthopedic trauma.Methods:A retrospective analysis was conducted of the 502 patients who had been treated operatively at Department of Orthopaedics and Trauma, Xi＇an Honghui Hospital from January 2015 to September 2018. They were divided into 2 groups according to the use of intraoperative blood transfusion. In the observation group of 203 cases who had received intraoperative blood transfusion, there were 98 males and 105 females with an age of (61.0±20.7) years; in the control group of 299 cases who had not received intraoperative blood transfusion, there were 166 males and 133 females with an age of (57.7±19.0) years. Blood coagulation series such as D-dimer and fibrinogen were measured at admission, 1 day pre-operation, 1 day and 3 days postoperation. After operation, venous ultrasound examination of both lower limbs was performed to observe postoperative DVT in the patients. The 2 groups were compared in changes in coagulation series and occurrence of postoperative DVT.Results:There was no statistically significant difference in the preoperative general data between the 2 groups ( P>0.05), showing they were comparable. There was no significant difference between the observation group and the control group in the D-dimer level at admission or 1 day pre-operation ( P>0.05), but the D-dimer levels at 1 day and 3 days postoperation in the observation group [4.18 (2.35, 7.08) mg/L and (6.20±3.77) mg/L] were significantly higher than those in the control group [3.41 (1.91, 5.63) mg/L and (4.05±2.62) mg/L] ( P<0.05). There was no statistically significant difference in fibrinogen between the 2 groups at different time points ( P>0.05). The incidence of DVT in the observation group was 43.3% (88/203), significantly higher than that in the control group (32.8%, 98/299) ( P<0.05). Conclusion:As intraoperative blood transfusion can increase the level of D-dimer and thus the incidence of postoperative venous thrombosis in patients with orthopaedic trauma, we should pay more attention to the risk of postoperative DVT in patients receiving intraoperative blood transfusion.

Objective:To explore the clinical efficacy of proximal femoral anatomical locking plate and autogenous iliac graft for failed primary internal fixation in treatment of femoral intertrochanteric fracture.Methods:A retrospective analysis was conducted of the 29 patients with femoral intertrochanteric fracture who had been treated after failed primary internal fixation at Department of Orthopaedics and Trauma, Xi'an Honghui Hospital between January 2014 and March 2017. They were 17 men and 12 women, aged from 35 to 83 years (mean, 68.7 years). Their primary internal fixation involved dynamic hip screw in 12 cases, proximal femoral locking plate in 13 cases, and intramedullary nail in 4 cases. The causes for their internal fixation failure included head cutting in 8 cases, fracture nonunion in 10 cases, plate or screw breakage in 6 cases, intramedullary nail breakage in 3 cases, and hip varus in 2 cases. Their revision surgery was performed with anatomical proximal femoral locking plate and autogenous iliac bone graft. Their fracture union time, and visual analogue scale (VAS), hip Harris score, SF-36 health survey scale and complications at the final follow-ups were recorded.Results:All the 29 patients were followed up for 12 to 24 months (18 months on average). Bony union was eventually achieved in all the 29 patients after an average time of 4.5 months (from 3 to 7 months). There were no such complications as nonunion, re-fracture or internal fixation failure. The VAS pain score at the final follow-up(4.6±1.6) was significantly lower than that before surgery(7.1±2.1), and the Harris hip score(85.2±8.2) and SF-36 score(75.9±15.5) at the final follow-up were significantly higher than those before surgery (48.0±12.7 and 48.7±18.8) (all P<0.05). According to their hip Harris scores at the final follow-ups, the therapeutic efficacy was rated as excellent in 9 cases, as good in 15 cases and as poor in one, yielding an excellent and good rate of 82.8%. Conclusion:For patients with femoral intertrochanteric fracture whose primary internal fixation has failed, especially those with fine femoral head and neck and hip joint, proximal femoral anatomic locking plate and autogenous iliac bone graft can result in satisfactory clinical efficacy.
