Risk factors for poor prognosis in patients with extracorporeal cardiopulmonary resuscitation / 中华急诊医学杂志

Objective:To analyze the clinical characteristics of patients undergoing extracorporeal cardiopulmonary resuscitation (ECPR), and to explore the risk factors leading to poor prognosis.Methods:The clinical data of 95 patients with ECPR admitted to the First Affiliated Hospital of Zhengzhou University from January 2020 to May 2023 were retrospectively analyzed. According to the survival status at the time of discharge, the patients were divided into the survival group and death group. The difference of clinical data between the two groups was compared to explore the risk factors related to death and poor prognosis. Risk factors associated with death were identified by Binary Logistic regression analysis. Results:A total of 95 patients with ECPR were included in this study, 62 (65.3%) died and 33 (34.7%) survived at discharge. Patients in the death group had longer low blood flow time [40 (30, 52.5) min vs. 30 (24.5, 40) min ] and total cardiac arrest time[40 (30, 52.5) min vs. 30(24.5, 40) min], shorter total hospital stay [3 (2, 7.25) d vs. 19 (13.5, 31) d] and extracorporeal membrane oxygenation (ECMO) assisted time [26.5 (17, 50) h vs. 62 (44, 80.5) h], and more IHCA patients (56.5% vs. 33.3%) and less had spontaneous rhythm recovery before ECMO (37.1% vs. 84.8%). Initial lactate value [(14.008 ± 5.188) mmol/L vs.(11.23 ± 4.718) mmol/L], APACHEⅡ score [(30.10 ± 7.45) vs. (25.88 ± 7.68)] and SOFA score [12 (10.75, 16) vs. 10 (9.5, 13)] were higher ( P< 0.05). Conclusions:No spontaneous rhythm recovery before ECMO, high initial lactic acid and high SOFA score are independent risk factors for poor prognosis in ECPR patients.

Surgical technique and effectiveness of titanium elastic nail assisted retrograde channel screw implantation in superior pubic branch / 中国修复重建外科杂志

OBJECTIVE@#To investigate the surgical technique and effectiveness of titanium elastic nail (TEN) assisted retrograde channel screw implantation of superior pubic branch.@*METHODS@#The clinical data of 31 patients with pelvic or acetabular fractures treated with retrograde channel screw implantation in superior pubic branch between January 2021 and April 2022 were retrospectively analyzed. Among them, 16 cases were implanted with assistance of TEN (study group) and 15 cases were implanted under the guidance of C-arm X-ray machine (control group). There was no significant difference in gender, age, cause of injury, Tile classification of pelvic fracture, Judet-Letournal classification of acetabular fracture, and time from injury to operation between the two groups ( P>0.05). The operation time, fluoroscopy times, and intraoperative blood loss of each superior pubic branch retrograde channel screw were recorded during operation. X-ray films and three-dimensional CT were reexamined after operation, the quality of fracture reduction was evaluated by Matta score standard, and the position of channel screw was evaluated by screw position classification standard. The fracture healing time was recorded during the follow-up, and the postoperative functional recovery was evaluated by Merle D'Aubigne Postel score system at last follow-up.@*RESULTS@#Nineteen and 20 retrograde channel screws of superior pubic branch were implanted in the study group and the control group, respectively. The operation time, fluoroscopy times, and intraoperative blood loss of each screw in the study group were significantly less than those in the control group ( P<0.05). According to the postoperative X-ray films and three-dimensional CT, none of the 19 screws in the study group penetrated out of the cortical bone or into the joint, and the excellent and good rate was 100% (19/19); in the control group, there were 4 screws of cortical bone penetration, and the excellent and good rate was 80% (16/20); the difference between the two groups was significant ( P<0.05). Matta score standard was used to evaluate the quality of fracture reduction, there was no patient in the two groups with poor reduction results, and the difference was not significant between the two groups ( P>0.05). The incisions of the two groups healed by first intention, and there was no complication such as incision infection, skin margin necrosis, and deep infection. All patients were followed up 8-22 months, with an average of 14.7 months. There was no significant difference in healing time between the two groups ( P>0.05). At last follow-up, the difference in functional recovery evaluated by the Merle D'Aubigne Postel scoring system between the two groups was not significant ( P>0.05).@*CONCLUSION@#TEN assisted implantation technique can significantly shorten the operation time of retrograde channel screw implantation of superior pubic branch, reduce the times of fluoroscopy, and have less intraoperative blood loss and accurate screw implantation, which provides a new safe and reliable method for minimally invasive treatment of pelvic and acetabular fractures.

Laparoscopic limited anatomical hepatectomy for hepatocellular carcinoma within the right anterior section: a propensity score matched study / 中华肝胆外科杂志

Objective:To study the efficacy of laparoscopic limited anatomical hepatectomy (LLAH) for hepatocellular carcinoma (HCC) within the right anterior section.Methods:The clinical data of 144 patients with HCC confined in the right anterior section undergoing hepatectomy at the First Affiliated Hospital of Army Medical University from January 2015 to December 2022 were retrospectively analyzed, including 122 males and 22 females, aged (54.5±9.7) years. Patients were divided into LLAH ( n=27), laparoscopic anatomical hepatectomy (LAH, n=69), and laparoscopic non-anatomical hepatectomy (LNAH, n=48). Propensity score matching was used to compare the operative time, postoperative hospital stay, postoperative complications, serum total bilirubin and albumin, and the prognostic indicators such as tumor-free survival (DFS) rate and cumulative survival rate between the groups. Results:After propensity score matching, there were 26 cases each in LLAH and LNAH group. There was no significant difference in operative time, intraoperative blood loss and postoperative hospital stay between LLAH group and LNAH group (all P<0.05). The total bilirubin and albumin in LLAH on the third day after operation were [ M( Q1, Q3)] 24.1(20.9, 29.1) μmol/L and (35.8±2.9) g/L, better than those in LNAH group 39.3(33.2, 57.0) μmol/L and (33.9±2.5) g/L, respectively. The 1- and 3-year DFS rates in LLAH group were 92.3% and 57.7%, higher than those in LNAH group (80.8% and 19.2%) (all P<0.05). After propensity score matching, there were 25 patients each in LLAH and LAH group. The operative time, postoperative hospital stay and postoperative complications of LLAH group were lower than those of LAH group, and the liver function parameters of LLAH group was also better than those of LAH group (all P<0.05). There was no significant difference in DSF rate between the two groups LLAH group and LAH group ( χ2=0.10, P=0.800). Conclusions:The perioperative outcome of LLAH for HCC within the right anterior section are similar to that of LNAH and better than that of LAH. The DFS of LLAH were better than that of LNAH and similar to that of LAH.

Tumor-targeting intravenous lipid emulsion of paclitaxel:Characteristics,stability,toxicity,and toxicokinetics / 药物分析学报

Lipid nanoemulsions are promising nanodrug delivery carriers that can improve the efficacy and safety of paclitaxel(PTX).However,no intravenous lipid emulsion of PTX has been approved for clinical treatment,and systemic safety profiles have not yet been reported.Here we outline the development of a PTX-loaded tumor-targeting intravenous lipid emulsion(PTX Emul)and describe its characteristics,colloidal stability,and systemic safety profiles in terms of acute toxicity,long-term toxicity,and tox-icokinetics.We also compare PTX Emul with conventional PTX injection.Results showed that PTX Emul exhibited an ideal average particle size(approximately 160 nm)with narrow size distribution and robust colloidal stability under different conditions.Hypersensitivity reaction and hemolysis tests revealed that PTX Emul did not induce hypersensitivity reactions and had no hemolytic potential.In addition,where the alleviated systemic toxicity of PTX Emul may be attributed to the altered toxicokinetic characteristics in beagle dogs,including the decreased AUC and increased plasma clearance and volume of distribution,PTX Emul alleviated acute and long-term toxicity as evidenced by the enhanced the median lethal dose and approximate lethal dose,moderate body weight change,decreased bone marrow suppression and organ toxicity compared with those under PTX injection at the same dose.A fundamental understanding of the systemic safety profiles,high tumor-targeting efficiency,and superior antitumor activity in vivo of PTX Emul can provide powerful evidence of its therapeutic potential as a future treatment for breast cancer.

Prospective study on the relationship between CCL22, a cord blood chemokine, and risk of atopic diseases / 临床儿科杂志

Objective To investigate the risk of atopic disease in infants with a atopic mothers. Methods The level of CCL22 and total IgE in the cord blood were measured using ELISA for 33 newborns with atopic mothers and for 44 newborns with non-atopic mothers. Correlation between the two factors was examined. Periodic follow-ups were conducted on the newborns to observe the risk of atopic diseases. Results The atopic group showed a higher level of CCL22 than that in non-atopic group, and the difference was statistically significant (Z=5.20, P=0.000). When 0.9 kU/L was taken as the threshold of an elevated IgE level in cord blood, the positive rates of the atopic group (11/33) was much higher than that of the non-atopic group (4/44) (χ2=7.07, P=0.008). Furthermore, the level of CCL22 and the level of IgE were significantly positively correlated (r=0.808, P=0.000; r=0.348, P=0.021) in the atopic group and the non-atopic group, respectively. During the 12 months of follow-up, the number of atopic diseases occurred in the infants in the atopic group (24/33) was much higher than that in the non-atopic group (10/44) (χ2=19.12, P<0.001).Significant correlation exists between levels CCL22 and total IgE in cord blood and infant atopic diseases (Z=5.36, P=0.000; Z=4.44, P=0.000). Conclusions At birth, the infants with an atopic mother are already in a sensitization state and have a tendency to develop potential atopic diseases. There is a correlation between the history of atopic diseases in the mothers and the elevated level of CCL22 in the cord blood of the newborns, and the probability of developing atopic diseases for the newborns is significantly higher when the level of CCL22 is elevated. The combined detection of CCL22 and IgE levels impact significantly on the prediction of the risk of atopic diseases clinically.

Correlation between diabetic distress and coping styles among patients with type 2 diabetes / 现代临床护理

Objective To investigate the correlation between diabetic distress and coping styles among patients with type 2 diabetes. Method One hundred inpatients with type 2 diabetes were engaged in the investigation of their diabetes distress and coping styles by the diabetes distress scale (DDS) and medical coping modes questionnaire (MCMQ) and the correlation between them. Results The average score of diabetic distress was (2.17 ± 0.71), which was at mild level. 57%of them were at the higher level of diabetic distress. Confrontation and avoidance dimensions were lower than the norm in coping styles, and the acceptance dimension was higher than the norm (all P<0.01). The average scores of diabetic distress, regimen-related distress and physician-related distress subscales were negatively correlated with confrontation (all P<0.05). The average score on diabetic distress and the subscales were positively correlated with avoidance and acceptance dimension (all P<0.01). Conclusions Diabetic distress is prevalent in type 2 diabetic patients and the degree of positive coping is still not insufficient. The diabetic distress is negatively correlated to the confrontation, and positively correlated to the avoidance and the acceptance dimension. The medical staff should instruct the patients to adopt positive coping styles, and avoid negative coping styles to reduce diabetic distress. It will be conductive to the physical and mental rehabilitation of the patients as well.

Correlation of perceived social support and job burnout with general well-being among caregivers in nursing homes / 现代临床护理

Objective To explore the correlations of perceived social support and burnout with general well-being among caregivers in nursing homes. Methods One hundred nursing workers were selected from three nursing homes in Guangzhou. Perceived social support scale ( PSSS ) , Maslach burnout inventory ( MBI ) and general well-being schedule ( GWBS ) were used to investigate the status of their support, burnout and general well-being and analyze the correlations between them. Results The scores on perceived social support, job burnout and general well-being were (59.00 ± 9.00), (2.49 ± 0.88), (77.19 ±9 .90), respectively, all at moderate level. The scores on emotional exhaustion and depersonalization were significantly higher than the norms (both P<0.001). Job burnout together with its three dimensions was negatively correlated with general well-being (all P<0.01), while perceived social support was positively correlated with general well-being ( P < 0 . 01 ) . The exogenous family support , emotional exhaustion and personal accomplishment influenced caregiver′s general well-being (all P<0.01). Conclusions Perceived social support, job burnout and general well-being are all at moderate level in caregivers of nursing homes. The higher the perceived social support, the lower the job burnout, the higher the passion and the general well-being in care workers. The general well-being of caregivers of the nursing homes was not high. The managers should pay more attention to them and measures should be taken to promote their physical and mental health.

Effects of vacuum sealing drainage on oxygen partial pressure and wound healing in rabbits / 中华急诊医学杂志

ObjectiveTo investigate the effect of vacuum sealing drainage (VSD) with different negative pressures on variation of oxygen partial pressure (PtO2 ) and wound healing in the rabbits.MethodsTwelve rabbit wound models were made and randomly (random number) divided into two groups, namely vacuum group ( n =6 )in which rabbits were treated with VSD by different negative pressures ( - 75 mmHg,- 125 mmHg,- 225 mmHg and - 350 mmHg) for 7 days, and routine treatment group ( n =6). At each interval of measurement, variation of PtO2 was measured by oxygen partial pressure admeasuring device, and area of VSD dressing and surface of wound were measured by vernier caliper, and growth of anaerobic bacteria was detected by bacterial culture, and morphological change and the course of wound healing were observed under by light microscope after HE tissue staining. Meanwhile anther two groups (n =6, in each) were set for comparing, including normal group, sham operation group. ResultsAverage PtO2 value of vacuum group was in the range of ( 1.87 +0. 19) kPa to ( 1.54 ±0. 21 ) kPa which was decreased gradually in 7 days under different negative pressures. Average PtO2 value of routine treatment group and normal group were ( 2. 82 ± 0. 37 ) kPa and ( 5.79 + 0. 50 ) kPa, respectively which weresignificant higher than that in vacuum group ( P ＜ 0. 01 ). PtO2 was fell to 80. 94％ of its original value after VSD for 5 seconds, and continued the downward trend with the increasing of negative pressure at the same interval of measuring. Area of VSD dressing significantly decreased to 65. 36％ of its original area after VDS for5 minutes (P＜0.01). Surface of wound was minimized to 62. 82％ of its original area after VSD for 7 days ( P ＜ 0. 01 ), and variations of those in - 350 mmHg group were significant greater than those in other groups ( P ＜ 0. 01 ). There was no evidence of anaerobic bacteria growth in vacuum group during this experiment. ConclusionsPtO2 could be down-regulated by VSD significantly without growth of anaerobic bacteria, and minimization of VSD dressing at - 350 mmHg was significantly helpful to reduce the area of wound for promoting the healing.
