OBJECTIVETo study the clinical characteristics of acute myocardial infarction (AMI) among younger adults and to explore the possible mechanisms of early myocardial infarction, combined with the newly discovered risk factors of coronary heart disease.
METHODSData on comparative analysis to the exposure rates of the risk factors and inducing factors of non-CAD patients with two groups of AMI patients including younger adults group (< or =40 years old) and aged adults group (> or =50 years old). Coronary angiography was applied.
RESULTSThere were differences noticed between the frequencies of risk factors of the two AMI groups. In younger adults group the exposure rates of smoking, hyperlipidemia, positive family history, C-reactive protein (CRP) and fibrinogen were markedly higher, while in elderly group the exposure rates of hypertension, smoking, hyperlipidemia, diabetes, CRP, fibrinogen and homocysteine (HCY) were markedly higher (P < 0.05). Although the clustering status of risk factors of the younger adult group was not higher than that of the elderly group. There were obvious inducing factors before the patients were attacked by AMI and the inducing factors inclined to cluster, which had obvious dose-reaction relationships with the occurrence of AMI in young people.
CONCLUSIONEarly AMI of younger adults might relate to the clustering status of inducing factors. The coexistence of several kinds of inducing factors was resulted in the occurrence of AMI of the atherosclerosis (As) and non-As patients by means of myocardial ischemia accumulation effect.

OBJECTIVE:
To investigate the effect of lateral prone position ventilation in patients with acute respiratory distress syndrome (ARDS).
METHODS:
A prospective control study was conducted. A total of 75 patients with moderate to severe ARDS admitted to the department of critical care medicine of Jingxian Hospital in Anhui province from January 2020 to December 2022 were selected as the research objects. According to the envelope method, the patients were divided into the lateral prone position ventilation group (38 cases) and the traditional prone position ventilation (PPV) group (37 cases), using lateral prone position ventilation and traditional PPV, respectively. The mechanical ventilation parameters were set according to the ARDS treatment guidelines and lung protective ventilation requirements in both groups, and the time of prone position for the first 3 times was not less than 16 hours per day. General data of patients were recorded, including heart rate (HR), mean arterial pressure (MAP), airway resistance and lung static compliance (Cst) before prone position (T0), 1 hour (T1), 4 hours (T2), 8 hours (T3), and before the end of prone position (T4), oxygenation index (PaO2/FiO2) before the first prone position (t0) and 12 hours (t1), 24 hours (t2), 48 hours (t3), and 72 hours (t4) after the intensive care unit (ICU) admission, as well as the incidence of pressure injury (PI) and vomiting, tracheal intubation time, and mechanical ventilation time. Repeated measures analysis of variance was used to compare the effects of different prone positions on patients before and after the prone position.
RESULTS:
There were no significant differences in age, gender, body mass index (BMI), acute physiology and chronic health evaluation II (APACHE II), underlying diseases, HR, MAP, pH value, PaO2/FiO2, blood lactic acid (Lac), arterial blood pressure of carbon dioxide (PaCO2) and other general information between the two groups. The HR (intergroup effect: F = 0.845, P = 0.361; time effect: F = 1.373, P = 0.247; interaction: F = 0.245, P = 0.894), MAP (intergroup effect: F = 1.519, P = 0.222; time effect: F = 0.169, P = 0.954; interaction: F = 0.449, P = 0.773) and airway resistance (intergroup effect: F = 0.252, P = 0.617; time effect: F = 0.578, P = 0.679; interaction: F = 1.467, P = 0.212) of T0-T4 between two groups showed no significant difference. The Cst of T0-T4 between the two groups showed no significant difference in the intergroup effect (F = 0.311, P = 0.579) and the interaction (F = 0.364, P = 0.834), while the difference in the time effect was statistically significant (F = 120.546, P < 0.001). The PaO2/FiO2 of t0-t4 between the two groups showed no significant difference in the intergroup effect (F = 0.104, P = 0.748) and the interaction (F = 0.147, P = 0.964), while the difference in the time effect was statistically significant (F = 17.638, P < 0.001). The group factors and time factors were tested separately, and there were no significant differences in the HR, MAP, airway resistance, Cst, PaO2/FiO2 between the two groups at different time points (all P > 0.05). The Cst at T1-T4 and PaO2/FiO2 at t1-t4 in the two groups were significantly higher than those at T0/t0 (all P < 0.05). There were no significant differences in the tracheal intubation time [days: 6.75 (5.78, 8.33) vs. 7.00 (6.30, 8.45)] and mechanical ventilation time [days: 8.30 (6.70, 9.20) vs. 7.40 (6.80, 8.75)] between the lateral prone position ventilation group and the traditional PPV group (both P > 0.05). However, the incidences of PI [7.9% (3/38) vs. 27.0% (10/37)] and vomiting [10.5% (4/38) vs. 29.7% (11/37)] in the lateral prone position ventilation group were significantly lower than those in the traditional PPV group (both P < 0.05).
CONCLUSIONS
Both lateral prone position ventilation and traditional PPV can improve Cst and oxygenation in patients with moderate to severe ARDS. The two types of prone position have little influence on HR, MAP and airway resistance of patients, and there is no difference in the influence on tracheal intubation time and mechanical ventilation time of patients. However, the lateral prone position ventilation mode can reduce the incidence of PI and vomiting, and is worthy of clinical promotion and application.

Objective:To observe the application effect of high-flow nasal canula oxygen therapy (HFNC) after extubation in patients with mechanical ventilation (MV) in the intensive care unit (ICU).Methods:A prospective study was conducted. From January 2018 to June 2020, 163 MV patients admitted to Yijishan Hospital of Wannan Medical College were enrolled, and they were divided into HFNC group (82 cases) and traditional oxygen therapy group (81 cases) according to the oxygen therapy model. The patients included in the study were given conventional treatment according to their condition. In the HFNC group, oxygen was inhaled by a nasal high-flow humidification therapy instrument. The gas flow was gradually increased from 35 L/min to 60 L/min according to the patient's tolerance, and the temperature was set at 34-37 ℃. The fraction of inspiration oxygen (FiO 2) was set according to the patient's pulse oxygen saturation (SpO 2) and SpO 2 was maintained at 0.95-0.98. A disposable oxygen mask or nasal cannula was used to inhale oxygen in the traditional oxygen therapy group, and the oxygen flow was 5-8 L/min, maintaining the patient's SpO 2 at 0.95-0.98. The differences in MV duration before extubation, total MV duration, intubation time, reintubation time, extubation failure rate, ICU mortality, ICU stay, and in-hospital stay were compared between the two groups, and weaning failure were analyzed. Results:There was no significant differences in MV duration before extubation (days: 4.33±3.83 vs. 4.15±3.03), tracheal intubation duration (days: 4.34±1.87 vs. 4.20±3.35), ICU mortality [4.9% (4/82) vs. 3.7% (3/81)] and in-hospital stay [days: 28.93 (15.00, 32.00) vs. 27.69 (15.00, 38.00)] between HFNC group and traditional oxygen therapy group (all P > 0.05). The total MV duration in the HFNC group (days: 4.48±2.43 vs. 5.67±3.84) and ICU stay [days: 6.57 (4.00, 7.00) vs. 7.74 (5.00, 9.00)] were significantly shorter than those in the traditional oxygen therapy group, the reintubation duration of the HFNC group was significantly longer than that of the traditional oxygen therapy group (hours: 35.75±10.15 vs. 19.92±13.12), and the weaning failure rate was significantly lower than that of the traditional oxygen therapy group [4.9% (4/82) vs. 16.0% (13/81), all P < 0.05]. Among the reasons for weaning failure traditional oxygen therapy group had lower ability of airway secretion clearance than that of the HFNC group [8.64% (7/81) vs. 0% (0/82), P < 0.05], there was no statistically differences in the morbidity of heart failure, respiratory muscle weakness, hypoxemia, and change of consciousness between the two groups. Conclusion:For MV patients in the ICU, the sequential application of HFNC after extubation can reduce the rate of weaning failure and the incidence of adverse events, shorten the length of ICU stay.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.
