Objective To investigate whether the geometry of the left heart and the diastolic function of left ventricle change in patients with essential hypertension but without left ventricular remodeling. Methods Echocardiography was performed in consecutive male patients above 35 years old and without valvular heart disease, myocardial infarction, cardiomyopathy or other diseases that may have effect on the heart structure. The thickness of intra-ventricular septum(IVST) and left ventricular posterior wall (LVPWT), the end-diastolic diameter of the left ventricle(LVEDD), left atrial anterior-posterior(LAAPD), long (LALD) and cross-sectional diameters(LACD) and area(LAA), early diastolic peak velocity(EPV) and atrial contraction peak velocity(APV) of the mitral valve flow were measured. EPV/APV ratio, left ventricular mass index(LVMI), relative wall thickness(RWT) were calculated. Patients with LVMI≥131g/m 2 and/or RWT≥0 44 were excluded from this study. The remaining patients were divided into 2 groups: the patients with essential hypertension were included in the no-remodeling group(group NR), while the patients without essential hypertention entered the normal control group (group NC). Student test was used to compare the variables between the two groups. Results There were 146 cases in group NC and 156 in group NR. IVST,LVPWT,LVEDD,LVMI,LAAPD,LALD,LACD and LAA of group NR were larger than those of group NC(P

Objective:To investigate the efficacy of alveolar lavage combined with montelukast in the treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and its effect on oxidative stress and inflammatory factors in patients.Methods:A prospective study was conducted involving 90 patients with AECOPD who were admitted to the Intensive Care Unit of Shan County Central Hospital from December 2021 to December 2022. The patients were randomly divided into a control group and an observation group, with 45 patients in each group, using the random number table method. The control group received conventional treatment, while the observation group was additionally treated with alveolar lavage combined with montelukast. Symptom score, Acute Physiology and Chronic Health Evaluation II score, overall response rate, serum levels of oxidative stress markers (malondialdehyde, 4-hydroxynonenal, and superoxide dismutase), and serum levels of inflammatory factors (C-reactive protein, tumor necrosis factor-α, interleukin-6, and procalcitonin) were compared between the two groups before and after treatment.Results:After treatment, the symptom scores for both groups decreased significantly compared with their respective scores before treatment ( t = 6.68, 11.32, both P < 0.05). After treatment, the symptom score in the observation group was significantly lower than that in the control group [(8.69 ± 0.84) points vs. (15.39 ± 1.18) points, t = 8.75, P < 0.05]. After treatment, the Acute Physiology and Chronic Health Evaluation II score in the observation group was significantly lower than that in the control group ( t = 9.19, P < 0.05). The overall response rate in the observation group was significantly higher than that in the control group [93.33% (42/45) vs. 75.56% (34/45), t = 4.56, P < 0.05]. After treatment, serum levels of 4-hydroxynonenal and malondialdehyde in the observation group were significantly lower than those in the control group ( t = 4.20, 5.15, both P < 0.05), while serum level of superoxide dismutase in the observation group was significantly higher than that in the control group ( t = 5.23, P < 0.05). After treatment, serum levels of C-reactive protein, tumor necrosis factor-α, interleukin-6, and procalcitonin in the observation group were significantly lower than those in the control group ( t = 6.86, 5.60, 8.75, 4.89, all P < 0.05). Conclusion:Alveolar lavage combined with montelukast can reduce clinical symptoms in patients with AECOPD, promote recovery, enhances clinical efficacy, decreases oxidative stress responses, increases the body's antioxidant capacity, lowers the expression of inflammatory factors, and reduces inflammatory responses.

Objective To investigate the effects of early mobilization therapy on gastrointestinal function and respiratory mechanics in mechanical ventilation patients with chronic obstructive pulmonary disease (COPD). Methods A prospective randomized controlled study was used. Eighty-five patients with COPD who had stable hemodynamics and required invasive mechanical ventilation from January to December 2017 were enrolled. The patients were divided into treatment group with 43 cases and control group with 42 cases according to the random number table method. The patients in both groups received conventional basic treatment, but the treatment group received early mobilization therapy. The conditions of acute gastrointestinal injury (AGI), incidence of ventilator-associated pneumonia (VAP), duration of mechanical ventilation, 28-day mortality and respiratory mechanics indexes before and after treatment including airway resistance (Raw), lung dynamic compliance (Cd), lung static compliance (Cs), intrinsic positive end expiratory pressure (PEEPi) were compared between 2 groups. Results There were no statistical difference in Raw, Cd, Cs and PEEPi before treatment between 2 groups (P＞0.05). The PEEPi and Raw after treatment in treatment group were significantly lower than those in control group:(6.51 ± 1.46) cmH2O (1 cmH2O=0.098 kPa) vs. (7.30 ± 1.61) cmH2O and (19.23 ± 2.62) cmH2O/(L·s) vs. (20.54 ± 2.50) cmH2O/(L·s), the Cs and Cd were significantly higher than those in control group:(53.14 ± 5.07) ml/cmH2O vs. (49.16 ± 5.10) ml/cmH2O and (26.63 ± 3.28) ml/cmH2O vs. (24.54 ± 1.97) ml/cmH2O, and there were statistical differences (P＜0.05 or＜0.01). The incidences of AGI, duration of AGI, duration of mechanical ventilation and incidence of VAP in treatment group were significantly lower than those in control group: 44.2% (19/43) vs. 66.7% (28/42), (3.56 ± 1.22) d vs. (4.26 ± 1.62) d, (6.79 ± 1.92) d vs. (7.64 ± 1.89) d and 2.3% (1/43) vs. 14.3% (6/42), the severity of AGI was significantly lower than that in control group (patients of gradeⅠ,Ⅱ,ⅢandⅣin treatment group were 11, 6, 1 and 1 case respectively, and patients of grade Ⅰ, Ⅱ, Ⅲ and Ⅳ in control group were 7, 12, 8 and 1 case respectively), and there were statistical differences (P＜0.05). There was statistical difference in 28-day mortality between 2 groups (P＞0.05). Conclusions The incidence of AGI in mechanical ventilation patients with COPD is high. Early mobilization therapy can reduce the incidence and duration of AGI in mechanically ventilated patients with COPD, and reduce airway resistance, increase Cd and Cs, reduce PEEPi, improve respiratory function, shorten mechanical ventilation time, and reduce the incidence of VAP, which is worthy of clinical promotion.

Objective To investigate the effect of high-flow nasal cannula oxygen therapy (HFNC) on the clinical efficacy and diaphragm function of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods The patients with mild to moderate AECOPD (clinical classification Ⅰ-Ⅱ) admitted to Huxi Hospital Affiliated to Jining Medical College from January to October in 2018 were enrolled. The patients were divided into HFNC treatment group and routine oxygen therapy control group (each n = 37) by randomly number table method. The two groups were given bronchiectasis drugs, corticosteroids, expectorant, anti-infection treatment, at the same time, the HFNC treatment group was given HFNC with the initial flow rate of 40 L/min. The routine oxygen therapy control group was given low flow oxygen, and the initial flow rate was 3 L/min. General data such as gender, age, clinical grade, acute physiology and chronic health evaluationⅡ (APACHEⅡ) score were recorded. Bedside ultrasound was used to measure the diaphragmatic excursions during quiet breathing (DEq), diaphragmatic excursions during deep breathing (DEd), and diaphragmatic shallow fast breathing index (D-RSBI) before and 2, 24 and 48 hours after treatment in both groups and compared, meanwhile, arterial blood gas analysis was performed, and arterial partial pressure of oxygen (PaO2) and arterial partial pressure of carbon dioxide (PaCO2) were recorded. Results Two patients in the HFNC treatment group withdrew from the study because they could not tolerate HFNC, while other patients were enrolled in the analysis. There was no statistically significant difference in gender, age, proportion of AECOPDⅡ grade or APACHEⅡscore between the two groups, indicating that the general data of the two groups were comparable and balanced. There was no statistically significant difference in DEq, DEd, D-RSBI, PaO2 or PaCO2 before treatment between the two groups. After treatment, DEp in both groups was decreased gradually with time, it was decreased earlier in the HFNC treatment group, and it showed significant difference as compared with that before treatment at 2 hours after treatment (mm: 18.3±3.1 vs. 20.1±4.2, P < 0.01), and it was significantly lower than that in the routine oxygen therapy control group (mm: 18.3±3.1 vs. 20.3±3.7, P < 0.05); DEd was gradually increased in both groups, it was significantly increased in the HFNC treatment group, and it was significantly higher than that in the routine oxygen therapy control group at 24 hours and 48 hours after treatment (mm: 55.2±7.6 vs. 50.8±9.2 at 24 hours, 59.4±7.7 vs. 53.6±9.1 at 48 hours, both P < 0.05); D-RSBI was decreased gradually in both groups, it was decreased earlier and more significant in the HFNC treatment group, and it was significantly lower than that in routine oxygen therapy control group at 24 hours and 48 hours after treatment (times·min-1·mm-1: 0.41±0.13 vs. 0.51±0.20 at 24 hours, 0.31±0.12 vs. 0.43±0.17 at 48 hours, both P < 0.05). After treatment, there was no statistically significant difference in PaO2 or PaCO2 between the two groups. Conclusion HFNC can effectively relieve diaphragm fatigue in patients with mild to moderate AECOPD, but it had no effect on carbon dioxide retention.

Objective: To investigate the effect of early mobilization on gastrointestinal function and delirium in patients with mechanical ventilation of chronic obstructive pulmonary disease(COPD). Methods: A total of 87 mechanically ventilated patients with COPD who met the inclusion criteria were selected as subjects from April 2017 to March 2018 in intensive care unit(ICU) of Huxi Hospital Affiliated to Jining Medical College.The patients were divided into treatment group (44 cases) and control group (43 cases) by the random number table method.On the basis of the same conventional treatment, the treatment group received early mobilization.The incidence of acute gastrointestinal injury(AGI), duration of AGI, incidence of delirium, duration of delirium, days of mechanical ventilation and 28-day mortality were compared between the two groups. Results: The incidence rate of AGI in the treatment group was lower than that in the control group[40.9%(18/44) vs. 62.7%(27/43)], and the duration in the treatment group was shortened[(3.95±1.62)d vs. (5.23±2.03)d], and the incidence rate of delirium in the treatment group was lower[54.5%(24/44) vs. 76.7%(33/43)], the duration of delirium in the treatment group was shortened[(2.36±0.9)d vs. (3.25±1.27)d], the mechanical ventilation time in the treatment group was decreased[(6.39±1.76)d vs. (7.56± 1.49)d], the differences were statistically significant(χ²=4.17, t=-2.280, χ²=4.744, t=-2.919, -3.358, all P<0.05). There was no statistically significant difference in the rate of 28-day mortality between the two groups[2.3%(1/43) vs. 9.3%(4/43), χ²=-1.984, P>0.05]. Conclusion Early mobilization can reduce the incidence and duration of AGI and delirium in COPD patients with mechanical ventilation, reduce the severity of AGI, and shorten the time of mechanical ventilation.

ObjectiveTo understand the health information needs of chronic disease inpatients and the current utilization of community health resources， and to analyze the influencing factors， so as to provide basis for personalized and high-quality health education for chronic disease inpatients and to guide them to make full use of community health resources. MethodsFrom November 2020 to February 2021， we conducted a face-to-face multi-center clinical epidemiological survey with paper questionnaire in three general hospitals of Shanghai. The study included 404 inpatients with diabetes， hypertension， coronary heart disease， chronic respiratory diseases， cancer and other chronic diseases. Results94.01% of the 404 respondents had different needs for disease or health related information， and there was no significant difference between patients of different ages， genders and educational backgrounds in their needs for health knowledge. Among these patients， only 39.11% of them participated in the establishment of a card for chronic disease management in the community or signed for a family doctor. The participation rate of male patients was lower than that of female patients （P<0.05）. ConclusionPatients with chronic diseases have a high demand for health related information， and we need to provide health information in multiple ways. We should increase investment in community health resources， improve service quality， and guide residents with chronic diseases to make full use of community health resources.
