Objective To analyze the publication profile and research hotspots of studies at home and abroad on postoperative cognitive dysfunction by bibliometric methods. Methods Literatures related to postoperative cognitive dysfunction published in the China National Knowledge Infrastructure (CNKI) and Web of Science databases from 2013 to 2023 were included, and statistical analysis was conducted by CiteSpace software. Results A total of 2 705 Chinese literatures and 2 412 English core literatures were included. The number of literatures on postoperative cognitive dysfunction showed an annual increase from 2013 to 2023; China was the country with the highest number of publications internationally, with Capital Medical University ranking the top among Chinese institutions; domestically, postoperative cognitive dysfunction researches predominantly focused on clinical studies, while overseas researches emphasized pathological mechanisms and basic investigations. Research hotspot analysis revealed an enhanced interest in the inflammatory mechanisms and anesthetic aspects of postoperative cognitive dysfunction. Conclusion From 2013 to 2023, the overall research at home and abroad interest in postoperative cognitive dysfunction has shown an upward trend, yet its pathophysiological mechanisms need further exploration. The risk factors for postoperative cognitive impairment and their correlations with anesthesia and mortality are being actively explored, and new methods for prevention and treatment such as percutaneous electrical stimulation are gradually emerging.

Objective:To investigate the clinical effect of respiratory intervention training in feeding of preterm infants, so as to provide reference for feeding interventions in preterm infants.Methods:From March 2021 to October 2021, the 80 preterm infants hospitalized in the Neonatal Intensive Care Unit of Xuzhou Central Hospital were selected and divided into intervention group (40 cases) and control group (40 cases) according to the random table method in a prospective study. The common nursing was given in the control group, the respiratory intervention training was given on this basis in the intervention group, once a day for two weeks. The intervention effect was evaluated by the time of indwelling gastric tube, hospital stay, feeding reaction, feeding related complications and satisfaction rate of catch-up growth. The oral feeding ability of preterm infants was evaluated by the non-nutritive sucking (NNS) score and preterm infants oral feeding readiness assessment scale (PIOFRAS) score.Results:The time of indwelling gastric tube and hospital stay was (15.3 ± 8.7), (28.9 ± 9.8) d in the intervention group and (21.7 ± 9.8), (34.6 ± 12.2) d in the control group, the difference was significant ( t=3.12, 2.32, both P<0.05). After intervention, the differences of respiratory number, heart rate and pulse oxygen saturation were (6.5 ± 1.3) beats/min, (11.2 ± 1.5) beats/min, 0.048 ± 0.015 in the intervention group and (11.2 ± 1.2) beats/min, (16.5 ± 1.3) beats/min, 0.082 ± 0.018 in the control group, the differences were significant ( t=16.39, 16.40, 9.35, all P<0.05). The incidence of feeding-related complications was 25.0% (10/40) in the intervention group and 55.0% (22/40) in the control group, the difference was significant ( χ2=7.50, P<0.05). The satisfaction rate of catch-up growth was 77.5%(31/40) in the intervention group and 40.0%(16/40) in the control group, the difference was significant ( χ2=12.78, P<0.05). The scores of NNS and PIOFRAS at 7 d, 10 d and 14 d after intervention were (13.73 ± 2.24), (29.98 ± 6.67), (49.08 ± 16.37) points and (15.28 ± 1.41), (25.08 ± 3.10), (31.03 ± 3.00) points in the intervention group and (10.30 ± 2.18), (15.68 ± 2.42), (28.60 ± 3.61) points and (12.60 ± 1.22), (17.15 ± 1.51), (23.75 ± 3.87) points in the control group, the differences were significant ( t values were -14.53--6.94, all P<0.05). Conclusions:The respiratory intervention training can effectively shorten the transition time from tube feeding to complete oral feeding in preterm infants, reduce feeding reaction and the incidence of feeding-related complications, and promote the coordination of feeding behavior, so as to improve oral feeding ability and catch-up growth of preterm infants.

Objective:To compare the clinical effectiveness between arthroscopic hollow screws combined with a suture anchor, hollow screws and proximal humerus internal locking system (PHILOS) in the treatment of split-type fractures of humeral greater tuberosity.Methods:A retrospective study was conducted to analyze the 54 patients with split-type fracture of humeral greater tuberosity who had been admitted to Department of Joint Surgery, Hospital of Traditional Chinese Medicine, Affiliated to Southwest Medical University from May 2015 to August 2020. There were 17 males and 37 females with an age of (58.4±12.1) years. According to different treatment methods, they were divided into 3 groups. Group A of 18 cases was treated with arthroscopic hollow screws combined with a suture anchor, group B of 18 cases with hollow screws, and group C of 18 cases with PHILOS. The length of surgical incision, and range of shoulder motion, visual analogue scale (VAS), and American Shoulder and Elbow Surgeons (ASES) score at the last follow-up were recorded and compared between the 3 groups.Results:There was no statistically significant difference in the preoperative general information between the 3 groups, indicating the 3 groups were comparable ( P>0.05). The surgical incision in group A [(0.7±0.1) cm] was the shortest, followed by (5.0±1.4) cm in group B, and (12.8±2.1) cm in group C, showing statistically significant differences in pairwise comparison ( P<0.05). In the 3 groups at the last follow-up, respectively, the shoulder forward flexion was 159.7°±13.4°, 154.9°±16.2°, and 160.5°±12.9°, and the shoulder abduction 149.6°±11.3°, 142.4°±12.0°, and 145.1°±10.4°, showing no statistically significant difference among the 3 groups ( P>0.05); the external rotation was 41.1°±8.1°, 38.1°±7.8° and 43.7°±6.2°, showing a statistically significant difference between groups B and C ( P<0.05); the dorsal extension was T 12 (L 5 to T 6), T 12 (L 5 to T 7), and T 12 (L 3 to T 6), showing no statistically significant difference among the 3 groups ( P>0.05). There was no statistically significant difference among the 3 groups in the VAS score or ASES score at the last follow-up ( P>0.05). Respectively, there were 2, 6, and 4 patients in groups A, B and C who developed complications, showing statistically significant differences between the 3 groups ( P<0.05). Conclusions:In the treatment of split fractures of humeral greater tuberosity, arthroscopic hollow screws combined with a suture anchor, hollow screws and PHILOS can all relieve pain and restore joint function of the shoulder. However, arthroscopic hollow screws combined with a suture anchor are the most recommendable due to their advantages in minimally invasiveness and reduction in complications.

Objective:To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test.Methods:This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ2 test. A kappa test was used to compare the consistency between groups. Results:After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea ( Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences ( P < 0.001). Conclusion:The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Objective:To investigate the effects of respiratory mechanics-guided sedation strategy on diaphragm function in chronic obstructive pulmonary disease (COPD) patients treated with mechanical ventilation (MV).Methods:A prospective study was conducted. Patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) received invasive MV who were admitted to the Affiliated Huxi Hospital of Jining Medical University from May 2020 to May 2021 were enrolled. The patients were divided into observational group and control group by random number table method. All patients were intubated for MV, and received bronchodilators, glucocorticoid, anti-infectives, expectorant, nutritional support, analgesia and sedation. The sedatives were dexmedetomidine combined with propofol, and the analgesics were sufentanil in both groups. Respiratory mechanics monitoring was performed every 6 hours in the observational group, and the depth of sedation was adjusted according to the parameters of respiratory mechanics: when airway resistance (Raw) > 20 cmH 2O·L -1·s -1, deep sedation was given to maintain Richmond agitation-sedation scale (RASS) ≤ -3; when the Raw was 10-20 cmH 2O·L -1·s -1, the initial depth of sedation maintained to reach the RASS score of -2-0; when Raw < 10 cmH 2O·L -1·s -1, withdrawn the sedation, or given light sedation, and maintained the RASS score of -2-0. While the control group received light sedation. The patients' diaphragmatic excursions (DE) was measured by bedside ultrasound, tidal volume (VT) and respiratory rate (RR) were recorded, and the diaphragmatic rapid shallow breathing index (D-RSBI, D-RSBI = RR/DE) and diaphragmatic excursion efficiency (DEE, DEE = VT/DE) were calculated. The differences in DE, D-RSBI, and DEE before and 3 days and 5 days of treatment between the two groups were compared. The difference in the RASS score within 3 days of sedation between the two groups was compared. The differences in the duration of MV and 28-day mortality between the two groups were compared. Results:A total of 96 patients were selected. Six patients were excluded due to delirium or the duration of MV shorter than 3 days. Finally, 90 patients were enrolled, with 46 in the observational group, and 44 in the control group. There were no statistically significant differences in DE, D-RSBI or DEE before treatment between the two groups. After treatment, D-RSBI in both groups was gradually decreased, and DEE was gradually increased with time. The D-RSBI at 3 days and 5 days of treatment in the observational group were significantly lower than those in the control group (times·min -1·mm -1: 1.73±0.48 vs. 1.96±0.35 at 3 days, 1.45±0.64 vs. 1.72±0.40 at 5 days, both P < 0.05), and DEE were significantly higher than those in the control group (mL/mm: 19.7±4.3 vs. 17.1±3.9 at 3 days, 25.8±5.6 vs. 22.9±5.4 at 5 days, both P < 0.05). There was no significant difference in DE at all time points between the two groups. The RASS scores within 2 hours of sedation in the observational group were significantly lower than those in the control group (1 day: -3.78±0.92 vs. -2.34±0.68, 2 days: -2.87±1.04 vs. -2.43±0.79, both P < 0.05), while no statistical difference at 3 days was found between the two groups. The duration of MV in the observational group was significantly shorter than that in the control group (days: 5.78±2.01 vs. 6.84±2.27, P < 0.05). One patient died in each of the control group and the observational group, and there was no significant difference in the 28-day mortality between the two groups (2.3% vs. 2.2%, P > 0.05). Conclusion:For AECOPD patients undergoing MV, respiratory mechanics-guided sedation strategy can reduce D-RSBI, increase DEE, shorten the duration of MV, and have a certain protective effect on the diaphragm.

Objective: To analyze the clinical characteristics of cases of novel coronavirus pneumonia and a preliminary study to explore the relationship between different clinical classification and liver damage. Methods: Consecutively confirmed novel coronavirus infection cases admitted to seven designated hospitals during January 23, 2020 to February 8, 2020 were included. Clinical classification (mild, moderate, severe, and critical) was carried out according to the diagnosis and treatment program of novel coronavirus pneumonia (Trial Fifth Edition) issued by the National Health Commission. The research data were analyzed using SPSS19.0 statistical software. Quantitative data were expressed as median (interquartile range), and qualitative data were expressed as frequency and rate. Results: 32 confirmed cases that met the inclusion criteria were included. 28 cases were of mild or moderate type (87.50%), and four cases (12.50%) of severe or critical type. Four cases (12.5%) were combined with one underlying disease (bronchial asthma, coronary heart disease, malignant tumor, chronic kidney disease), and one case (3.13%) was simultaneously combined with high blood pressure and malignant tumor. The results of laboratory examination showed that the alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (ALB), and total bilirubin (TBil) for entire cohort were 26.98 (16.88 ~ 46.09) U/L and 24.75 (18.71 ~ 31.79) U/L, 39.00 (36.20 ~ 44.20) g/L and 16.40 (11.34- ~ 21.15) mmol/L, respectively. ALT, AST, ALB and TBil of the mild or moderate subgroups were 22.75 (16.31- ~ 37.25) U/L, 23.63 (18.71 ~ 26.50) U/L, 39.70 (36.50 ~ 46.10) g/L, and 15.95 (11.34 ~ 20.83) mmol/L, respectively. ALT, AST, ALB and TBil of the severe or critical subgroups were 60.25 (40.88 ~ 68.90) U/L, 37.00 (20.88 ~ 64.45) U/L, 35.75 (28.68 ~ 42.00) g/L, and 20.50 (11.28 ~ 25.00) mmol/L, respectively. Conclusion The results of this multicenter retrospective study suggests that novel coronavirus pneumonia combined with liver damage is more likely to be caused by adverse drug reactions and systemic inflammation in severe patients receiving medical treatment. Therefore, liver function monitoring and evaluation should be strengthened during the treatment of such patients.

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.

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.
