ABSTRACT
Objective:To observe the correlation between the frontal P-wave axis and the severity of chronic obstructive pulmonary disease (COPD) and the prognosis evaluation system.Methods:Patients with COPD>45 years old who were followed up in the outpatient department of Hunan Chest Hospital from January to July 2022 were continuously selected as subjects. At the same time, the healthy people who examined in the health management center of our hospital were in the control group. Both groups of subjects completed electrocardiogram and pulmonary function tests. The level of frontal P-wave axis and the results of pulmonary function examination were recorded, and the differences of frontal P-wave axis between the COPD group and the control group were compared, so as to clarify the value of frontal P-wave axis in the diagnosis, disease severity and prognosis evaluation of COPD.Results:The level of forced expiratory volume in the first second/forced vital capacity(FEV1/FVC )in the COPD group was significantly lower than that in the control group, while the level of P-wave axis was significantly higher than that in the control group (all P<0.05). The receiver operating characteristic (ROC) curve of P-wave axis showed that the AUC of P-wave axis in predicting COPD was 0.96 ( P<0.001), the best cut-off value was 63.80, the sensitivity was 0.89, and the specificity was 0.93. There were significant difference in P-wave axis level, the forced expiratory volume in one second to forced vital capacity ratio (FEV 1%pred), body mass index (BMI) and BMI, airflow obstruction, dyspnea, and exercise capacity (BODE) index between groups according to the degree of airflow limitation (all P<0.05). Correlation analysis showed that P-wave axis level was positively correlated with BODE index ( r=0.77, P<0.001), and negatively correlated with pulmonary function FEV 1%pred ( r=-0.76, P<0.001). Conclusions:There is a good correlation between the level of frontal P-wave axis and the severity of COPD and the prognosis evaluation system, which has clinical application value.
ABSTRACT
The cardiovascular diseases, which have the increasing incidence and high mortality rate, have brought a great impact on people′s lives and health.Being lipid inclusions with 30~150 nm in diameter, exosomes can be secreted by most cells in the body, and proteins, lipids, nucleic acids and other substances derived from those cells are wrapped inside.Exosomes play a variety of biological roles in the communication between cells, such as mediating immune response, inflammatory response, cell migration and differentiation.Research on exosomes has made significant progress, and the roles of exosomes in cardiovascular diseases have consequently attracted more and more attention in recent years.The communication of exosomes between cardiomyocytes and between heart and peripheral tissues has provided new strategies for the diagnosis and treatment of cardiovascular diseases.Application of exosomes in the diagnosis and treatment of cardiovascular diseases such as heart failure, viral myocarditis, Kawasaki disease and dilated cardiomyopathy is summarized in this review.
ABSTRACT
Objective To explore the joint contact force, ligament tensile force and force transmission mode of foot internal structure in Down’s syndrome child (DSC) during standing. Methods The finite element models of foot were constructed based on CT image data from one DSC and one typically developing child (TDC). The models were validated by plantar pressure measurement during static standing. To simulate foot force during standing, the ground reaction force and the triceps surae force were applied as the loading condition. Contact pressure of the tibiotalar, talonavicular and calcaneocuboid joints, tensile force of the spring and plantar calcaneocuboid ligaments, and force transmission mode in transverse tarsal joints were calculated and analyzed. Results The finite element models of foot were validated to be reliable. Compared with the TDC, the DSC showed higher contact pressure at the tibiotalar joint and lower contact pressure at the talonavicular joint. The tensile force of spring and plantar calcaneocuboid ligaments of DSC was 10 times and 58 times of TDC, respectively. The forces transmitted through both mediate and lateral columns in DSC were lower than those in TDC. Conclusions Abnormal contact pressure of the tibiotalar joint, larger tensile force of midfoot ligaments and smaller force of the transverse tarsal joint were found in DSC during standing. The abnormal alteration of stress patterns in foot internal structure of DSC should be fully considered in clinical rehabilitation, so as to provide theoretical references for screening and making intervention plans for early rehabilitation, as well as designing individualized orthopedic insoles.
ABSTRACT
Five patients with mediastinal bronchogenic cyst (MBC) were treated with endoscopic submucosal tunnel dissection (ESTD) between January 2018 and October 2019 at the Department of Gastroenterology in Henan Provincial People′s Hospital. Lesions were located in the middle or lower esophageal level, with diameters≤3.5 cm. The tunnel establishment time was 13-18 min, and the tumor stripping time was 30-51 min. The number of titanium clips used for tunnel closure was 5-8. The tumors were completely resected. No major bleeding or hypoxemia occurred during the operation and no serious adverse reactions occurred after the operation. Postoperative pain scores were all ≤3. The hospital stay was 4-7 days. There was no tumor residue and recurrence during 4-23 months of follow-up.It is suggested that ESTD for MBC which derived from post mediastinum and located at the lower or middle level esophagus is safe and effective.
ABSTRACT
OBJECTIVE：To c ompare the effects o f intravenous anesthesia with remimazolam and propofol on perioperative cellular immune function in patients underwent radical mastectomy. METHODS ：Eighty patients underwent selective radical mastectomy were collected ，and then randomly divided into remimazolam group （group R ）and propofol group （group P ）. During anesthesia induction ，group R was intravenously injected with remimazolam 0.2 mg/kg+sufentanil 0.3 μg/kg+cisatracurium 0.2 mg/kg；group R was intravenously injected with propofol 2 mg/kg+sufentanil 0.3 μg/kg+cisatracurium 0.2 mg/kg. During anesthesia maintenance，group R was intravenously pumped with remimazolam 0.4-1.2 mg/（kg·h）+remifentanil 0.1-0.2 μg（/ kg·min）；group P was intravenously pumped with propofol 4-10 mg/（kg·h）+remifentanil 0.1-0.2 μg（/ kg·min）. Both groups were given intravenous injection of cisatracurium intermittently. The anesthesia depth was monitored during the operation and the pumping speed of remimazolam，propofol and remifentanil was adjusted accordingly. The intraoperative infusion volume ，blood loss ，operation time ， opioid dosage ，and visual analogue scale （VAS）scores at 24 and 72 hours after operation were recorded in 2 groups；at the same time，the levels of T lymphocyte CD 3+，CD4+，CD8+ and NK cells were measured 30 min before anesthesia induction ，24 h and 72 h after operation ；CD4+/CD8+ was also calculated. The incidence of ADR was recorded in 2 groups. RESULTS ：There was no statistical significance in intraoperative infusion volume ，blood loss ，operation time ，opioid dosage ，VAS score at 24，72 hours after operation and the incidence of ADR between 2 groups（P＞0.05）. Compared with 30 min before anesthesia induction ，the levels of CD 3+，CD4+，NK cells and CD 4+/CD8+ ratio in 2 groups at 24 hours after operation were significantly decreased （P＜ 0.05）；compared with group P ，the levels of CD 3+，CD4+ and NK cells as well as CD 4+/CD8+ ratio in group R increased significantly in group R （P＜0.05）. CONCLUSIONS ：For anesthesia maintenance ，the inhibitory effects of remimazolam on perioperative cellular immunity in patients underwent radical mastectomy are poorer than propofol.

They were randomly divided into group SD and group Dex according random number table ，with 40 cases in each group. At the same time ，40 patients with preoperative PSQI score ＜7 were selected as group C. Thirty min before anesthesia induction ，Dexmedetomidine hydrochloride injection 0.4 μg/kg was injected intravenously in group Dex. Etomidate emulsion injection ，Sufentanil citrate injection and Rocuronium bromide injection were used for anesthesia induction in 3 groups，and Ropofol medium/long chain fat emulsion injection + Remifentanil hydrochloride for injection was used to maintain anesthesia. The drug use ，operation time ，PACU stay time and postoperative hospital stay were recorded in 3 groups. The cognitive function was evaluated 2 h before operation and 1，3，5，7 days after operation. The occurrence of POD was observed. The plasma levels of IL- 6 and S 100β were measured 2 h before operation ，2 h after operation ，1，3，5 days after operation. The occurrence of ADR was recorded. RESULTS ：There was no statisti cal significance in intraoperativ e drug use and operation time among 3 groups （P＞0.05）. The PACU stay time ， the incidence of POD and the duration of POD in group SD an d lixxi18@126.com group Dex were significantly higher or longer than group C ， while the Dex group was significantly lower or shorter thangroup SD （P＜0.05）. The postoperative hospitalization stay ofgroup SD was significantly longer than group C and group Dex （P＜0.05），and there was no statistical significance between group Dex and group C （P＞0.05）. Before operation ，there was no statistical significance in MMSE scores or plasma levels of IL- 6 and S100β among 3 groups（P＞0.05）. MMSE scores of group C 1，3 days after operation ，those of group SD and group Dex 1，3，5 and 7 days after operation were significantly lower than those before operation. MMSE scores of group SD and group Dex 1，3，5 and 7 days after operation were significantly lower than group C at corresponding period ；the group Dex was significantly higher than the group SD at corresponding period （P＜0.05）. The plasma levels of IL- 6 and S 100 β at different time points were significantly higher than before operation ，and the group SD and group Dex were significantly higher than the group C ，and the group Dex was significantly lower than group SD at corresponding period （P＜0.05）. There was no statistical significance in the total incidence of ADR among 3 groups（P＞0.05）. CONCLUSIONS ：SD can promote the occurrence of POD in liver tumor resection elderly patients. Dexmetomidine can reduce the incidence of POD in elderly patients with preoperative SD ，the mechanism of which may be associated with the inhibition of IL- 6 and S 100β expression and the alleviation of brain injury with good safety.
ABSTRACT
Objective:To observe and compare the changes of pulmonary function in patients with pulmonary tuberculosis regular treatment for 3 months.Methods:From April 2018 to June 2019, 500 tuberculosis patients who received regular anti tuberculosis treatment in our hospital were selected.The pulmonary function of patients with pulmonary tuberculosis was measured before treatment and at the end of three months; the results of pulmonary ventilation function, lung volume, diffusing capacity, and the value of forced vital capacity (FVC), maximum expiratory volume in 1 second (FEV 1), maximum expiratory volume in 1 second/forced vital capacity (FEV 1/FVC), total lung volume (TLC), residual volume (RV), carbon monoxide diffusing capacity (D LCO) were compared. Results:252 patients with pulmonary tuberculosis were included. Before treatment and at the end of three months, the abnormal pulmonary function results were 204 cases (80.95%) and 193 cases (76.59%), respectively, and the difference was not statistically significant ( P>0.05). Among them, abnormal pulmonary ventilation function is the most common, especially with obstructive, followed by abnormal diffusing capacity. At the end of three months, the proportions of patients with normal pulmonary ventilation function and normal lung volume were higher than that before treatment ( P<0.05), but there was no significant difference in the proportion of normal diffusing capacity before and after treatment ( P>0.05). The values of FVC, FEV 1, TLC and D LCO at the end of three months were higher than those before treatment, and the difference was statistically significant ( t=-6.414, -6.754, -3.863, -3.311, all P<0.01). Conclusions:Most patients with pulmonary tuberculosis have abnormal pulmonary function. At the end of the three months treatment, the normal rates of the pulmonary ventilation function and lung volume as well as the values of FVC, FEV 1, TLC and D LCO in patients with pulmonary tuberculosis were significantly improved compared with those before treatment.

ABSTRACT
Objectives To investigate the changes of erythropoietin(EPO)expression in rats after focal cerebral ischemia/reperfusion injury.Methods Male Sprague-Dawley rats were randomly divided into normal,sham,cerebral ischemic/reperfusion(CIR)groups.Middle cerebral artery occlusion(MACO)model was established by Longa's method,and reperfusion was followed 2 hours after occlusion in CIR group.The rats' brain neurological deficit scores were evaluated at 24 h,48 h,72 h and 96 h after reperfusion.The protein expression of EPO was determined by immunohistochemistry staining and Western blotting in each time points.Results The rats' brain neurological deficit scores at 48 h,72 h and 96 h were significantly increased(3.40±0.32,3.60±0.17,3.70±0.21,all P<0.05)compared with those at 24 h(3.00±0.22)after reperfusion in CIR group.The results of immunohistochemistry staining and Western blotting showed that the positive expression of EPO proteins in rats started at 24 h(0.36±0.05,140.20±0.30)after cerebral ischemic/reperfusion injury,increased significantly at 48 h(1.09±0.10,145.40±0.16),reached the peak at 72 h(1.29±0.09,156.23±0.12),began to decline at 96 h(0.98±0.04,141.56±0.36).Conclusions Cerebral ischemia and reperfusion injury can induce increased expression of EPO protein,which suggests that EPO may have protective effect on nerve cells under the condition of ischemia and reperfusion.
ABSTRACT
Objective To evaluate the effects of age factors on hypothermia-induced reduction of ischemia-reperfusion(I/R)injury in isolated rat hearts.Methods Pathogen-free healthy aged male Sprague-Dawley rats,aged 18-20 months,weighing 400-600 g,and young rats,aged 4-6 months,weighing 280-350 g,were used in the study.After the animals were anesthetized with intraperitoneal chloral hydrate and heparinized,their hearts were excised and perfused with K-H solution in a Langendorff apparatus.Twenty-four isolated hearts of aged rats were assigned into 2 groups(n=12 each)using a random number table:I/R group(group AI/R)and hypothermia group(group AH).Twenty-four isolated hearts of young rats were assigned into 2 groups(n=12 each)using a random number table:I/R group(group YI/R)and hypothermia group(group YH).Perfusion was suspended for 30 min followed by 120 min reperfusion to establish the model of I/R.The temperature was maintained at 37 ℃ during the whole process in AI/R and YI/R groups.The hearts were perfused with 34 ℃ K-H solution until 120 min of reperfusion starting from onset of reperfusion in AH and YH groups.At 30 min of equilibration(T0)and 15,30,60 and 120 min of reperfusion(T1-4),heart rate(HR),left ventricular developed pressure(LVDP),the maximum rate of increase in left ventricular pressure(+dp/dtmax),and the minimum rate of increase in left ventricular pressure(+dp/dtmin)were recorded.Six hearts from each group were randomly selected at T4,and myocardial specimens were obtained for determination of ATP,superoxide dismutase(SOD)and malondialdehyde(MDA)levels and myocardial infarct size(IS).Results Compared with group YI/R,HR was significantly decreased at T1-4,ATP and SOD levels were increased,and the MDA content and myocardial IS were decreased in group YH,and the HR,LVDP,+dp/dtmax and +dp/dtmin at T0 and ATP and SOD levels at T4 were significantly decreased,and the MDA content and myocardial IS were increased in group AI/R(P<0.05).Compared with group YH,HR,LVDP,+dp/dtmax and +dp/dtmin at T0 and ATP and SOD levels at T4 were significantly decreased,and the MDA content and myocardial IS were increased in group AH(P<0.05).Compared with group AH,the levels of ATP and SOD were significantly decreased,and the MDA content and myocardial IS were increased in group AI/R(P<0.05).Conclusion Age factors affect the efficacy of hypothermia in reducing I/R injury in isolated rat hearts,and hypothermia provides better cardioprotection for young rats than for aged rats.
