OBJECTIVE:
To compare the effectiveness of a zero-profile three-dimensiaonal (3D)-printed microporous titanium alloy Cage and a conventional titanium plate combined with a polyether-ether-ketone (PEEK)-Cage in the treatment of single-segment cervical spondylotic myelopathy (CSM) by anterior cervical discectomy and fusion (ACDF).
METHODS:
The clinical data of 83 patients with single-segment CSM treated with ACDF between January 2022 and January 2023 were retrospectively analyzed, and they were divided into 3D-ZP group (35 cases, using zero-profile 3D-printed microporous titanium alloy Cage) and CP group (48 cases, using titanium plate in combination with PEEK-Cage). There was no significant difference in gender, age, disease duration, surgical intervertebral space, and preoperative Japanese Orthopaedic Association (JOA) score, visual analogue scale (VAS) score, neck disability index (NDI), vertebral height at the fusion segment, Cobb angle, and other baseline data between the two groups (P>0.05). The operation time, intraoperative blood loss, hospital stay, complications, interbody fusion, and prosthesis subsidence were recorded and compared between the two groups. VAS score, NDI, and JOA score were used to evaluate the improvement of pain and function before operation, at 3 months after operation, and at last follow-up, and the vertebral height at the fusion segment and Cobb angle were measured by imaging. The degree of dysphagia was assessed by the Bazaz dysphagia scale at 1 week and at last follow-up.
RESULTS:
The operation was successfully completed in all the 83 patients. There was no significant difference in intraoperative blood loss and hospital stay between the two groups (P>0.05), but the operation time in the 3D-ZP group was significantly shorter than that in the CP group (P<0.05). Patients in both groups were followed up 24-35 months, with an average of 25.3 months, and there was no significant difference in the follow-up time between the two groups (P>0.05). The incidence and grade of dysphagia in CP group were significantly higher than those in 3D-ZP group at 1 week after operation and at last follow-up (P<0.05). There was no dysphagia in 3D-ZP group at last follow-up. There was no complication such as implant breakage or displacement in both groups. The intervertebral fusion rates of 3D-ZP group and CP group were 65.71% (23/35) and 60.42% (29/48) respectively at 3 months after operation, and there was no significant difference between the two groups [OR (95%CI)=1.256 (0.507, 3.109), P=0.622]. The JOA score, VAS score, and NDI significantly improved in the 3D-ZP group at 3 months and at last follow-up when compared with preoperative ones (P<0.05), but there was no significant difference between the two groups (P>0.05). There was no significant difference in the improvement rate of JOA between the two groups at last follow-up (P>0.05). At 3 months after operation and at last follow-up, the vertebral height at the fusion segment and Cobb angle significantly improved in both groups, and the two indexes in 3D-ZP group were significantly better than those in CP group (P<0.05). At last follow-up, the incidence of prosthesis subsidence in 3D-ZP group (8.57%) was significantly lower than that in CP group (29.16%) (P<0.05).
CONCLUSION
The application of zero-profile 3D-printed Cage and titanium plate combined with PEEK-Cage in single-segment ACDF can both reconstruct the stability of cervical spine and achieve good effectiveness. Compared with the latter, the application of the former in ACDF can shorten the operation time, reduce the incidence of prosthesis subsidence, and reduce the incidence of dysphagia.

OBJECTIVE:
To evaluate the effectiveness of the single-stage anterior eccentric kyphotic distraction reduction technique (EKD-RT) for treating lower cervical dislocation with locked facet joints, assessing its reduction success rate, neurological improvement, and safety.
METHODS:
A retrospective analysis was conducted on 67 patients with lower cervical dislocation and locked facet joints (21 unilateral, 46 bilateral) treated between January 2015 and January 2024. There were 39 males and 28 females, with an average age of 49.5 years (range, 22-75 years). The injured segments included C 3, 4 in 4 cases, C 4, 5 in 13 cases, C 5, 6 in 22 cases, and C 6, 7 in 28 cases. The interval between injury and admission ranged from 2 hours to 2 days (mean, 5.6 hours). Preoperative Frankel grading included grade A in 9 cases, grade B in 28 cases, grade C in 17 cases, grade D in 11 cases, and grade E in 2 cases. Japanese Orthopaedic Association (JOA) score was 7.0±1.4. All patients underwent single-stage anterior cervical discectomy and fusion. Following discectomy at the dislocated level, the EKD-RT was applied to unlock and reduce the locked facet joints, followed by internal fixation. Operation time, blood loss, reduction success rate, and complications were recorded. Interbody fusion status was evaluated using Bridwell criteria. Neurological status was assessed pre- and post-operatively using Frankel grading. Spinal cord function was scored using the 17-point JOA score, and the improvement rate was calculated.
RESULTS:
Successful reduction of the locked facet joints achieved in all cases. The operation time was 41-85 minutes (range, 63.3 minutes), and intraoperative blood loss was 50-360 mL (range, 125.0 mL). Complications included cerebrospinal fluid leakage in 2 cases; no severe complications such as major vascular injury or recurrent laryngeal nerve injury occurred. All patients were followed up 12-24 months (mean, 17.9 months). At last follow-up, radiological examination confirmed interbody fusion in all patients, with no implant failure or migration. The Frankel grading included grade A in 3 cases, grade B in 9 cases, grade C in 13 cases, grade D in 16 cases, and grade E in 26 cases; the JOA score reached 13.7±2.3; all of which significantly improved compared to preoperative levels ( P<0.05). The improvement rate of JOA score was 66.1%±24.7%.
CONCLUSION
The EKD-RT is an effective surgical approach for lower cervical dislocation with locked facet joints. It enables safe and efficient reduction of the locked facet joints via a single incision, resulting in significant neurological improvement with a low complication rate.

Objective:To investigate the establishment method, coordination points and safe transport management strategy of vena-arterial extracorporeal membrane oxygenation (VA-ECMO) in patients with downtime difficulties during cardiopulmonary bypass (CPB).Methods:A observation study was conducted. The patients admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to October 2022 were enrolled. These patients could not be separated from CPB and received VA-ECMO-assisted CPB surgery. The clinical data of the patients were recorded, including the basic information of the patients, the data of VA-ECMO establishment and transport process, the clinical indicators before and after VA-ECMO installation, the operation data of VA-ECMO and clinical outcomes. The experience was summarized from the aspects of extracorporeal membrane oxygenation (ECMO) establishment, transport process, team cooperation, and adverse events during transport. The clinical indicators before and after ECMO operation were compared. According to whether ECMO was successfully weaned, the patients were divided into a successful weaning group and a failure weaning group, and the clinical data between the two groups were compared.Results:Eighteen patients who underwent VA-ECMO-assisted CPB were enrolled, including 10 males and 8 females. The average age was (56.7±12.3) years old. Preoperative left ventricular ejection fraction (LVEF) was 0.46±0.10, and the main reasons for switching to VA-ECMO assistance included right ventricular systolic weakness in 6 cases, total cardiac systolic weakness in 5 cases, left ventricular systolic weakness in 4 cases, high pulmonary arterial pressure in 2 cases, and intractable ventricular fibrillation in 1 case. Among the 18 patients transferred from CPB to VA-ECMO, 10 cases were successfully weaned and 8 cases failed. In ICU, 8 cases survived, 5 cases died, and 5 cases gave up treatment and discharged. The average time for successful CPB to VA-ECMO establishment was (24.6±7.4) minutes, initial blood flow was (3.3±0.4) L/min, and transit time was (8.4±1.5) minutes. ECMO-assisted duration averaged (82.0±69.3) hours. Adverse events occurred in 9 patients during ECMO establishment and transfer. Post-ECMO onboarding for 4 hours, significant improvements were noted in blood lactic acid (Lac), pH value, mean arterial pressure (MAP), central venous oxygen saturation (ScvO 2) as compared with pre-ECMO onboarding [Lac (mmol/L): 10.5±7.0 vs. 15.2±6.8, pH value: 7.38±0.92 vs. 7.26±0.87, MAP (mmHg, 1 mmHg≈0.133 kPa): 74.9±13.7 vs. 58.4±17.0, ScvO 2: 0.678±0.065 vs. 0.611±0.061, all P < 0.01], and vasoactive-inotropic score (VIS) was also decreased (39.8±29.8 vs. 68.9±64.4, P < 0.01). Compared with successful weaning group, the patients in the failed weaning group exhibited higher pre-machine Lac (mmol/L: 18.8±7.8 vs. 12.3±4.3, P < 0.05), longer CPB time [minutes: 238.0 (208.8, 351.2) vs. 200.0 (185.8, 217.0), P < 0.05], and shorter ECMO-assisted time [hours: 19.5 (11.0, 58.8) vs. 94.5 (65.8, 179.8), P < 0.01]. However, there was no statistically significant difference in pre-machine pH value, ScvO 2, MAP, VIS score, and initial blood flow and establishment time of ECMO between the two groups. Conclusions:VA-ECMO is an effective circulatory aid for CPB surgery that cannot be weaned after CPB. The establishment and transfer of CPB "bridge" to ECMO aid depends on multi-disciplinary treatment (MDT) cooperation. The success rate of ECMO weaning is related to the Lac and CPB duration. If it is not possible to detach from the CPB successfully, VA-ECMO should be initiated as early as possible.

Objective:To investigate the effect of dexmedetomidine-based anesthesia on gastrointestinal function in the patients undergoing laparoscopic radical resection for colorectal cancer.Methods:One hundred patients, aged 40-70 yr, with body mass index of 18-29 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ to Ⅲ, scheduled for elective laparoscopic radical resection for colorectal cancer, were divided into 2 groups ( n=50 each) using a random number table method: dexmedetomidine group (group D) and control group (group C). In group D, dexmedetomidine was intravenously infused as a bolus of 0.5 μg/kg at 10 min before anesthesia induction, followed by a continuous infusion of 0.5 μg·kg - 1·h - 1 until the end of surgery. In group C, the equal volume of normal saline was administered at the same time points. Patient-controlled intravenous analgesia was performed with hydromorphone, flurbiprofen, and metoclopramide after operation. Oxycodone was taken orally for rescue analgesia when visual analog scale score> 3. Serum intestinal fatty acid-binding protein concentrations were determined using an enzyme-linked immunosorbent assay at 10 min before anesthesia induction (T 1), 10 min after establishing pneumoperitoneum (T 2), immediately after tumor resection (T 3), 30 min before the end of surgery (T 4), and 1 h after the end of surgery (T 5). Gastrointestinal function was assessed using the I-FEED scoring system at 1-6 days after surgery.The intraoperative consumption of propofol and remifentanil, time to first flatus, first defecation and first oral intake and duration of hospital stay after surgery, and requirement for rescue analgesia within 3 days after surgery were recorded. Results:Compared with group C, the serum intestinal fatty acid-binding protein concentrations were significantly decreased at T 3-T 5, the I-FEED scores were decreased on postoperative days 3-5, the intraoperative consumption of propofol and remifentanil was decreased, and the time to first flatus, first defecation and first oral intake and duration of hospital stay were shortened ( P<0.05), and no significant difference was found in the rate of rescue analgesia in group D ( P>0.05). Conclusions:Dexmedetomidine-based anesthesia can promote the recovery of postoperative gastrointestinal function in the patients undergoing laparoscopic radical resection for colorectal cancer.

The prevalence of diabetes in China is increasing year by year, and has become a health issue of close concern to the whole society. Glucagon-like peptide-1 (GLP-1) receptor agonist (GLP-1RA), as a new class of glucose-lowering drugs, is now widely used in the treatment of type 2 diabetes mellitus (T2DM) because of its significant glucose-lowering efficacy and low risk of hypoglycemia. As the level of evidence for its effects on improving cardiovascular system and renal protection and reducing body mass continues to improve, its status in the treatment guidelines for T2DM is gradually increasing. Currently, nine GLP-1RA drugs have been approved for the clinical treatment of T2DM in China. Although all of these drugs exert hypoglycemic effects based on the activation of GLP-1 receptors in the body, the differences in their own structures and natural GLP-1 amino acid homology lead to large differences in pharmacokinetic parameters and clinical efficacy among different analogs. In order to enable clinicians and pharmacists to have a full understanding of the characteristics and clinical evidence of these analogs and to better perform their therapeutic effects, Liaoning Provincial Pharmaceutical Society organized clinical medicine and pharmacy experts to develop a medication guide for nine GLP-1RA drugs to provide a reference for clinical medication needs and promote rational and standardized use by compiling and summarizing the pharmacological characteristics, clinical applications, adverse reactions, interactions, the medications in special populations and medication management.

OBJECTIVE:
To investigate the incidence and risk factors of hypothermia in patients with acute renal injury (AKI) receiving continuous renal replacement therapy (CRRT), and to compare the effects of different heating methods on the incidence of hypothermia in patients with CRRT.
METHODS:
A prospective study was conducted. AKI patients with CRRT who were admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to December 2022 were enrolled as the study subjects. Patients were divided into dialysate heating group and reverse-piped heating group according to randomized numerical table method. Both groups were provided with reasonable treatment mode and parameter setting by the bedside physician according to the patient's specific condition. The dialysis heating group used the AsahiKASEI dialysis machine heating panel to heat the dialysis solution at 37 centigrade. The reverse-piped heating group used the Barkey blood heater from the Prismaflex CRRT system to heat the dialysis solution, and the heating line temperature was set at 41 centigrade. The patient's temperature was then continuously monitored. Hypothermia was defined as a temperature lower than 36 centigrade or a drop of more than 1 centigrade from the basal body temperature. The incidence and duration of hypothermia were compared between the two groups. Binary multivariate Logistic regression analysis was used to explore the influencing factors of hypothermia during CRRT in AKI patients.
RESULTS:
A total of 73 patients with AKI treated with CRRT were eventually enrolled, including 37 in the dialysate heating group and 36 in the reverse-piped heating group. The incidence of hypothermia in the dialysis heating group was significantly lower than that in the reverse-piped heating group [40.5% (15/37) vs. 69.4% (25/36), P < 0.05], and the hypothermia occurred later than that in the reverse-piped heating group (hours: 5.40±0.92 vs. 3.35±0.92, P < 0.01). Patients were divided into hypothermic and non-hypothermic groups based on the presence or absence of hypothermia, and a univariate analysis of all indicators showed a significant decrease in mean arterial pressure (MAP) in hypothermic patients (n = 40) compared with the non-hypothermic patients [n = 33; mmHg (1 mmHg ≈ 0.133 kPa): 77.45±12.47 vs. 94.42±14.51, P < 0.01], shock, administration of medium and high doses of vasoactive drug (medium dose: 0.2-0.5 μg×kg-1×min-1, high dose: > 0.5 μg×kg-1×min-1) and CRRT treatment were significantly increased [shock: 45.0% (18/40) vs. 6.1% (2/33), administration of medium and high doses of vasoactive drugs: 82.5% (33/40) vs. 18.2% (6/33), administration of CRRT (mL×kg-1×h-1): 51.50±9.38 vs. 38.42±10.97, all P < 0.05], there were also significant differences in CRRT heating types between the two groups [in the hypothermia group, the main heating method was the infusion line heating, which was 62.5% (25/40), while in the non-hypothermia group, the main heating method was the dialysate heating, which was 66.7% (22/33), P < 0.05]. Including the above indicators in a binary multivariate Logistic regression analysis, it was found that shock [odds ratio (OR) = 17.633, 95% confidence interval (95%CI) was 1.487-209.064], mid-to-high-dose vasoactive drug (OR = 24.320, 95%CI was 3.076-192.294), CRRT heating type (reverse-piped heating; OR = 13.316, 95%CI was 1.485-119.377), and CRRT treatment dose (OR = 1.130, 95%CI was 1.020-1.251) were risk factors for hypothermia during CRRT in AKI patients (all P < 0.05), while MAP was protective factor (OR = 0.922, 95%CI was 0.861-0.987, P < 0.05).
CONCLUSIONS
AKI patients have a high incidence of hypothermia during CRRT treatment, and the incidence of hypothermia can be effectively reduced by heating CRRT treatment fluids. Shock, use of medium and high doses of vasoactive drug, CRRT heating type, and CRRT treatment dose are risk factors for hypothermia during CRRT in AKI patients, with MAP is a protective factor.
