ObjectiveTo analyze the factors influencing meropenem-related liver injury （MRLI） and to explore their clinical predictive value. MethodsA retrospective case-control study was conducted， and the Chinese Hospital Pharmacovigilance System （CHPS） was used to establish a retrieval scheme. A total of 1 625 hospitalized cases using meropenem from January 2018 to December 2022 were collected. Patients were divided into case group （n=62） and control group （n=1 563） based on the presence or absence of liver injury. Clinical data and laboratory indicators from both groups were collected and analyzed. The t-test was used for comparison of normally distributed continuous data between the two groups， while the Mann-Whitney U test was used for comparison of continuous data not conforming to a normal distribution. The chi-square test was used for comparison of categorical data between the two groups. A multivariate Logistic regression analysis was performed to identify the influencing factors for MRLI. A Logistic regression equation was established， and the predictive value of these factors was assessed using the receiver operating characteristic （ROC） curve. ResultsThe results of univariate analysis indicated that the rates of male patients， hypoproteinemia， shock， intensive care unit （ICU） admissions， sepsis， and liver， gallbladder， and cardiovascular diseases， the levels of alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， gamma-glutamyl transpeptidase （GGT）， aspartate aminotransferase （AST）， creatinine （CREA）， and procalcitonin （PCT）， and the number of hospitalization days were significantly higher in the case group than in the control group （P<0.05）， and that the platelet levels in the case group were significantly lower than those in the control group （P<0.05）. The multivariate Logistic regression analysis showed that male sex （odds ratio ［OR］=2.080， 95% confidence interval ［CI］： 1.050 — 4.123， P=0.036）， admission to the ICU （OR=8.207， 95%CI： 4.094‍ ‍—‍ ‍16.453， P<0.001）， comorbidity with gallbladder disease （OR=8.240， 95%CI： 3.605‍ ‍—‍ ‍18.832， P<0.001）， ALP （OR=1.012， 95%CI： 1.004‍ ‍—‍ ‍1.019， P=0.004）， GGT （OR=1.010， 95%CI： 1.005‍ ‍—‍ ‍1.015， P<0.001）， and PLT （OR=0.997， 95%CI： 0.994‍ ‍—‍ ‍0.999， P=0.020） were the influential factors for MRLI. The areas under the ROC curve of ALP， GGT， and PLT were 0.589， 0.637， and 0.595， respectively， and the AUC of them combined was 0.837. ConclusionMale sex， ICU admission， comorbidity with gallbladder disease， increased ALP， increased GGT， and decreased PLT were influencing factors for MRLI， and a combination of factors has a better predictive value for the occurrence of MRLI.

Background:Acupuncture(AP)is widely used in hospitalized patients.However,high-quality evidence supporting its use in patients with sepsis-induced gastrointestinal dysfunction remains limited.Objective:This study aims to conduct a systematic review and meta-analysis to evaluate the effects of AP in patients with sepsis-induced gastrointestinal dysfunction.Methods:PubMed,Embase,Web of Science,SinoMed,VIP Database,Wanfang Data Knowledge Service Platform,China National Knowledge Infrastructure,and the Cochrane Library were searched from inception to March 10,2024.We included randomized controlled trials(RCTs)that focused on adult patients with sepsis receiving AP and compared them with a control group.The primary outcome was gastrointestinal indicators.Sensitivity analysis,subgroup analysis,and assessment of publication bias were conducted to explore the potential heterogeneity among the included studies.Results:A total of 23 RCTs involving 1603 patients were included.Overall,AP significantly improved gastrointestinal indicators,including intra-abdominal pressure(mean difference[MD]=-1.97cm H2O;95％confidence interval[CI]:-2.77,-1.16;P＜0.00001),bowel sounds(MD=0.91 per minute;95％CI:0.66,1.16;P＜0.00001),and gastric residual volume(MD=-46.94mL;95％CI:-83.45,-10.43;P=0.01).These findings were corroborated by subgroup and sensitivity analyses.AP also showed significant benefits in inflammation indicators(procalcitonin,tumor necrosis factor-α,and interleukin-6),gastrointestinal function indicators(D-lactate,diamine oxidase,intestinal fatty acid-binding protein,and motilin),disease severity scores(Acute Physiology and Chronic Health Evaluation Ⅱ score and gastrointestinal dysfunction score),clinical prognosis,and other critical clinical outcomes(total effective rate and time to achieve target enteral nutrition)(all P values＜0.05).Additionally,the mortality rate in the AP group was comparable to that of the control group.Conclusion:Our findings suggest that AP significantly improves gastrointestinal indicators and other clinical outcomes in patients with sepsis and gastrointestinal dysfunction,indicating its potential as a promising therapeutic option.However,due to the small sample sizes and substantial heterogeneity among the included studies,further high-quality,multicenter RCTs are needed to validate these results.

Overall, AP significantly improved gastrointestinal indicators, including intra-abdominal pressure (mean difference [MD] = -1.97 cm H O; 95% confidence interval [CI]: -2.77, -1.16; P < 0.00001), bowel sounds (MD = 0.91 per minute; 95% CI: 0.66, 1.16; P < 0.00001), and gastric residual volume (MD = -46.94 mL; 95% CI:-83.45, -10.43; P = 0.01). These findings were corroborated by subgroup and sensitivity analyses. AP also showed significant benefits in inflammation indicators (procalcitonin, tumor necrosis factor-α, and interleukin-6), gastrointestinal function indicators(D-lactate, diamine oxidase, intestinal fatty acid-binding protein, and motilin), disease severity scores (Acute Physiology and Chronic Health Evaluation II score and gastrointestinal dysfunction score), clinical prognosis, and other critical clinical outcomes (total effective rate and time to achieve target enteral nutrition) (all P values < 0.05).

Objective:To clarify the application effect of information-guided enteral nutrition-associated diarrhea (ENAD) management process in patients with chronic obstructive pulmonary disease (COPD) undergoing non-invasive assisted ventilation.Methods:A mixed cohort study of pre- and post-control was conducted. Thirty-nine patients with COPD who were admitted to the emergency intensive care unit (ICU) of Huzhou First People's Hospital from July 1, 2021 to July 31, 2022 were enrolled. Taking the completion of the software development of ENAD management software for critically ill patients on January 28, 2022 as the time node, 20 patients admitted from July 1, 2021 to January 28, 2022 were set as the control group, and 19 patients admitted from January 29 to July 31, 2022 were set as the observation group. The two groups of patients received the same enteral nutrition support treatment, and the control group implemented the conventional ENAD treatment process with enteral nutrition intolerance disposal process as the core. On the basis of the control group, the observation group implemented the information-guided ENAD treatment process, and the system software actively captured the information of ENAD patients and reminded the medical team to improve the patient's diarrhea-related examination and provide alternative treatment plans. The duration of antidiarrhea, feeding interruption rate, and energy and protein intake, blood biochemical indexes, incidence of abnormal blood electrolyte metabolism, daily continuous non-invasive assisted ventilation and endotracheal intubation after 7 days of targeted diarrhea intervention were compared between the two groups.Results:Except for the basal pulse rate, there were no significant differences in gender distribution, age, and vital signs, basic nutritional status, arterial blood gas analysis and blood biochemistry at admission between the two groups, indicating comparability between the two groups. When ENAD occurred, the patients in the observation group obtained earlier cessation of diarrhea than those in the control group [days: 3.00 (2.00, 3.25) vs. 4.00 (3.00, 5.00), P < 0.01], and the feeding interruption rate was significantly lower than that in the control group [10.53% (2/19) vs. 65.00% (13/20), P < 0.01]. After 7 days of diarrhea intervention, the energy intake of the observation group was significantly higher than that of the control group [kJ·kg -1·d -1: 66.28 (43.34, 70.36) vs. 47.88 (34.60, 52.32), P < 0.01], the levels of hemoglobin (Hb), albumin (Alb) and serum prealbumin (PAB) were significantly higher than those in the control group [Hb (g/L): 119.79±10.04 vs. 110.20±7.75, Alb (g/L): 36.00 (33.75, 37.25) vs. 31.00 (30.00, 33.00), PAB (mg/L): 155.79±25.78 vs. 140.95±14.97, all P < 0.05], the daily continuous non-invasive assisted ventilation duration was significantly shorter than that of the control group [hours: 14 (12, 16) vs. 16 (14, 18), P < 0.01], and the arterial partial pressure of carbon dioxide (PaCO 2) was significantly lower than that of the control group [mmHg (1 mmHg ≈ 0.133 kPa): 66.00 (62.00, 70.00) vs. 68.00 (67.50, 70.05), P < 0.05]. However, there were no significant differences in protein intake, incidence of abnormal electrolyte metabolism, and incidence of endotracheal intubation due to acute respiratory failure between the two groups. Conclusion:The information-guided ENAD treatment process can enable the COPD patients undergoing continuous non-invasive assisted ventilation who experience ENAD to receive earlier cessation of diarrhea, and improve the protein energy metabolism and respiratory function of the patients.

Objective To investigate the clinical efficacy of tiotropium bromide in the treatment of patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)complicated with acute respiratory failure.Methods A total of 106 patients with AECOPD complicated with acute respiratory failure admitted to the First People's Hospital of Huzhou from March 2019 to March 2022 were selected and divided into observation group and control group according to random number table method,with 53 cases in each group.Both groups were given routine treatment.The control group was treated with noninvasive biphasic positive airway pressure ventilation.The observation group was treated with tiotropium bromide on the basis of control group.Both groups were treated for 14 days.The clinical efficacy,lung function,blood gas index,inflammatory factors and adverse reactions were compared between two groups.Results The total effective rate of observation group was significantly higher than that of control group(94.34%vs.79.25%,χ2=5.267,P=0.023).After treatment,forced expiratory volume in one second(FEV1),FEV1/forced vital capacity,peak expiratory flow,pH,percutaneous arterial oxygen saturation and arterial partial pressure of oxygen in observation group were significantly higher than those in control group(P<0.05),while arterial partial pressure of carbon dioxide,interleukin-6,interleukin-8,tumor necrosis factor-α and hypersensitive C-reaction protein were lower than those in control group(P<0.05).There were no significant differences in the incidence of adverse drug reactions and ventilator adverse reactions between two groups(P>0.05).Conclusion Titropium bromide in the treatment of AECOPD complicated with acute respiratory failure can significantly improve the curative effect,improve pulmonary function and arterial blood gas,but attention should be paid to the timely treatment of adverse reactions of dry mouth.

To examine the molecular epidemiology of carbapenem-resistant Klebsiella pneumoniae (CRKP) and investigate the horizontal transmission of blaKPC and blaNDM genes for the prevention and treatment of CRKP. A total of 49 clinically isolated CRKP strains were retrospectively analyzed from January to December 2022 at The First Hospital of Hunan University of Chinese Medicine. Phenotypic screening was performed using modified carbapenem inactivation assay (mCIM) and EDTA-carbapenem inactivation assay (eCIM). Polymerase chain reaction (PCR) was utilized to identify carbapenem resistance genes, β-lactamase resistance genes, and virulence genes, while multi-locus sequence analysis (MLST) was employed to assess the homology of CRKP strains. Conjugation experiments were conducted to infer the horizontal transmission mechanism of blaKPC and blaNDM genes. The results showed that the study included 49 CRKP strains, with 44 carrying blaKPC and 8 carrying blaNDM, Three strains were identified as blaKPC+ blaNDM-CRKP. In this study, 28 out of 49 CRKP strains (57.2%) were found to carry virulence genes. Additionally, one CRKP strain tested positive in the string test and was found to carry both Aerobactin and rmpA virulence genes. MLST results revealed a total of 5 ST types, with ST11 being predominant (41/49, 83.7%). Successful conjugation was observed in all 3 blaKPC-CRKP strains, while only 1 out of 3 blaNDM-CRKP strains showed successful conjugation. The transconjugant exhibited significantly reduced susceptibility to imipenem and cephalosporin antibiotics. In conclusion, the resistance mechanism of CRKP in this study is primarily attributed to the production of KPC enzymes, along with the presence of multiple β-lactamase resistance genes. Additionally, there is a local prevalence of hv-CRKP and blaKPC+ blaNDM-CRKP. blaKPC and blaNDM can be horizontally transmitted through plasmids, with varying efficiency among different strains.

Objective:To investigate the efficacy of phenolamine in the treatment of sepsis-induced myocardial dysfunction and its effect on cardiac function, myocardial injury index, and hemodynamics in patients.Methods:The clinical data of 79 patients with sepsis-induced myocardial dysfunction who received treatment in Huangshi Central Hospital, Edong Healthcare Group from February 2017 to February 2020 were retrospectively analyzed. These patients were divided into a control group (without phenolamine treatment, n = 41) and an observation group (with phenolamine treatment, n = 38) according to whether they received phenolamine treatment or not. Clinical efficacy, cardiac function, myocardial injury index, and hemodynamic index pre- and post-treatment were compared between the two groups. Results:There was no significant difference in 28-day mortality rate between the two groups ( P > 0.05). Intensive care unit length of stay and mechanical ventilation duration in the observation group were (9.33 ± 3.52) days and 83.00 (28.50, 138.00) hours, which were significantly shorter than (12.17 ± 4.15) days and 111.00 (47.50, 169.00) hours in the control group ( t = 3.26, Z = -2.27, both P < 0.05). The response rate in the observation group was significantly higher than that in the control group [81.58% (31/38) vs. 60.98% (25/41), χ2 = 4.05, P < 0.05]. After 7 days of treatment, the left ventricular ejection fraction in each group was significantly increased, and the left ventricular end-diastolic diameter and left ventricular end-systolic diameter in each group were significantly decreased compared with before treatment (all P < 0.05). After 7 days of treatment, the left ventricular ejection fraction in the observation group was significantly higher than that in the control group ( t = 3.29, P < 0.05), and left ventricular end-diastolic diameter and left ventricular end-systolic diameter were significantly lower than those in the control group ( t = 5.94, 11.21, both P < 0.05). N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in each group were significantly decreased with time (both P < 0.05). At 24 and 72 hours and 7 days after treatment, N-terminal pro-brain natriuretic peptide and cardiac troponin I levels in the observation group were significantly lower than those in the control group (both P < 0.05). After 7 days of treatment, heart rate in each group decreased significantly compared with that before treatment (both P < 0.05), mean arterial pressure, cardiac index, and stroke output index in each group increased significantly compared with those before treatment (all P < 0.05). After 7 days of treatment, heart rate in the observation group was significantly lower than that in the control group ( t = 4.90, P < 0.05), and mean arterial pressure, cardiac index, and stroke output index in the observation group were significantly higher than those in the control group ( t = 4.37, 3.23, 6.01, all P < 0.05). Conclusion:Phentolamine can improve hemodynamics, reduce myocardial injury and improve cardiac function in patients with sepsis-induced myocardial dysfunction.

Objective:To analyze blood transfusion and prognostic factors of extracorporeal membrane pulmonary oxygenation (ECMO) for the treatment of respiratory and circulatory failure.Methods:The clinical data of 80 patients with respiratory and circulatory failure who received treatment in Huangshi Central Hospital from March 2016 to July 2021 were retrospectively analyzed. According to 28-day prognosis, these patients were divided into death group ( n = 44) and survival group ( n = 36). The general data, blood transfusion during the process of ECMO, vital signs, laboratory indicators, ventilation time, and length of hospital stay were compared between the two groups. The factors affecting death during the process of ECMO were analyzed. Results:There were no significant differences in sex, age, body mass index, complications, the cause of respiratory and circulatory failure, and the mode of ECMO between the two groups (all P > 0.05). Preoperative Acute Physiology and Chronic Health Evaluation II score, creatinine, procalcitonin and lactic acid levels in the survival group were (22.36 ± 3.71) points, (79.17 ± 9.29) μmol/L, (2.77 ± 0.79) ng/L, (2.74 ± 0.36) mmol/L, respectively, which were significantly lower than (34.27 ± 4.98) points, (94.16 ± 10.23) μmol/L, (3.69 ± 1.10) ng/L, (5.18 ± 0.42) mmol/L, respectively in the death group ( t = -11.89, -6.79, -5.62, -27.53, all P < 0.001). There were no significant differences in preoperative respiratory frequency, diastolic pressure, systolic pressure, heart rate, oxygenation index (PaO 2/FiO 2) and C-reactive protein between the two groups (all P > 0.05). The volume of blood transfused on the day of undergoing ECMO, the volume of blood transfused on the day of withdrawing ECMO, the volume of blood transfused during the whole process of ECMO, duration of ventilation, and the incidence of complications related to ECMO were(98.74 ± 16.28) mL, (37.23 ± 10.36) mL, (398.79 ± 67.81) mL, (210.39 ± 20.21) hours, 38.89% (14/36), respectively, which were significantly lower than (160.17 ± 23.14) mL, (48.26 ± 12.25) mL, (600.23 ± 70.12) mL, (320.14 ± 18.21) hours, 79.55% (35/44), respectively in the death group ( t = -13.43, -4.29, 4.94, 25.25, χ2 = 13.79, all P < 0.001). The length of hospital stay in the survival group was longer than that in the death group [(20.14 ± 5.36) days vs. (14.17 ± 4.23) days, t = 5.56, P < 0.001). Acute Physiology and Chronic Health Evaluation II score, procalcition level, the volume of blood transfused on the day of ECMO, duration of ventilation, and the volume of blood transfused during the whole process of ECMO are risk factors for death after ECMO, while length of hospital stay is a protective factor for ECMO. Conclusion:Preoperative evaluation of Acute Physiology and Chronic Health Evaluation II score, continuous blood transfusion during the whole process of ECMO, grasping the opportunity of ventilation and preventing against complications of ECMO are the keys to increasing the survival rate of patients with respiratory and circulatory failure.
