Abstract
Background Diabetic neurogenic bladder (DNB) is one of the autonomic neuropathies of diabetes mellitus (DM), with an incidence rate reaching 40-60%. This study combined bladder function rehabilitation training and mecobalamin to treat a patient with DNB to provide reference for clinical work. Case Description A 67-year-old woman was admitted to our hospital on 5 December 2018, with a 3-year history of dysuria that had progressively worsened for 15 days. The patient was treated with pelvic floor myofascial manipulation combined with Kegel training and mecobalamin for 6 months. Pelvic organ prolapse (POP), pelvic floor surface electromyography (EMG), psychological status, and quality of life were evaluated before, during, and after treatment, and the changes in urodynamics were observed. After comprehensive rehabilitation treatment, the patient's POP, pelvic floor muscle strength, mental state, and quality of life were significantly improved. The results of the urodynamic examination showed that the patient's safe bladder capacity reached 500 mL after treatment, in contrast to the first safe bladder capacity measurement of 90 mL. The symptoms of ureteral reflux disappeared, the detrusor compliance increased from 2 to 20 mL/cmH2O, which roughly indicated a return to healthy function. However, there was no detrusor contraction in the bladder during urination. Conclusions This patient achieved good curative effect after the treatment of comprehensive pelvic floor rehabilitation combined with mecobalamin. However, the safe capacity of the patient reported in this case showed a small bladder safe capacity, and the patient's detrusor muscle did not contract during urination. Thus, urination in this patient may be accomplished by increasing abdominal pressure. When treating patients with atypical neurogenic bladder, the adverse effects caused by excessive abdominal pressure and abdominal wall relaxation need to be considered.

Abstract
Early diagnosis and treatment can reduce the symptoms of Attention Deficit/Hyperactivity Disorder (ADHD) in children, but medical diagnosis is usually delayed. Hence, it is important to increase the efficiency of early diagnosis. Previous studies used behavioral and neuronal data during GO/NOGO task to help detect ADHD and the accuracy differed considerably from 53% to 92%, depending on the employed methods and the number of electroencephalogram (EEG) channels. It remains unclear whether data from a few EEG channels can still lead to a good accuracy of detecting ADHD. Here, we hypothesize that introducing distractions into a VR-based GO/NOGO task can augment the detection of ADHD using 6-channel EEG because children with ADHD are easily distracted. Forty-nine ADHD children and 32 typically developing children were recruited. We use a clinically applicable system with EEG to record data. Statistical analysis and machine learning methods were employed to analyze the data. The behavioral results revealed significant differences in task performance when there are distractions. The presence of distractions leads to EEG changes in both groups, indicating immaturity in inhibitory control. Importantly, the distractions additionally enhanced the between-group differences in NOGO α and γ power, reflecting insufficient inhibition in different neural networks for distraction suppression in the ADHD group. Machine learning methods further confirmed that distractions enhance the detection of ADHD with an accuracy of 85.45%. In conclusion, this system can assist in fast screenings for ADHD and the findings of neuronal correlates of distractions can help design therapeutic strategies.

Abstract
Acute lung injury (ALI) is a spectrum of acute and life-threatening pulmonary inflammatory conditions. Treatment of ALI remains a clinical challenge. Recently, intermittent fasting (IF) has been shown to improve health and alleviate many diseases. In this study, we tested whether IF attenuated ALI and investigated the mechanism underlying this process. In vivo, the effects of IF on ALI were evaluated in a lipopolysaccharide (LPS)-induced murine ALI model. We found that two times of 24-h fasting in a week before ALI efficiently ameliorated LPS-induced lung injury in mice, characterized by alleviated lung lesions, wet-to-dry weight ratio, myeloperoxidase activity, malondialdehyde content, and lower levels of tumor necrosis factor-α, interleukin-6, and interleukin-1β. In vitro, functional assays were conducted to assess IF on the inflammatory response and macrophage polarization of bone marrow-derived macrophages (BMDMs) treated with LPS or IL-4. And PPARγ antagonist GW9662 and AMPK siRNA were used to test the role of PPARγ and AMPK in the IF-mediated improvement of ALI. The results showed that IF (serum deprivation) suppressed macrophage M1 activation and promoted M2 activation in LPS-treated BMDMs. While, IF also augmented macrophage M2 polarization in IL-4-treated BMDMs. Further mechanistic studies showed that the promotive effect of IF on M2 polarization was related to the activation of the PPARγ and AMPK pathways. In conclusion, this study suggests that IF enhances M2 polarization by activating the AMPK and PPARγ pathways, thus facilitating anti-inflammatory response and ameliorating ALI.

Abstract
Objective: To explore the feasibility and clinical value of sentinel lymph node (SLN) biopsy through cervix-uterine combined two-step injection with two tracers in patients with early stage endometrial cancer. Methods: From July 2019 to April 2021, a total of 73 patients, aged (54.2±3.3) year, who were preoperatively diagnosed as stage Ⅰ-Ⅱ endometrial cancer (including 56 low-risk patients and 17 medium-high risk patients) in Affiliated Hospital of Qingdao University were selected. According to the different sites of tracer injection, the patients were randomly divided into three groups: cervical injection group (25 cases): 1 ml of nano-carbon was used to inject at 3 and 9 o'clock in the cervix; uterine injection group (21 cases): the magnetic resonance imaging examination was performed to determine the location of the lesion, and 4 ml of methylene blue was injected into the uterine body at 2 sites where the lesion was located; combined injection group (27 cases): cervical injection of nano-carbon (1 ml) combined with uterine injection of methylene blue (4 ml). The SLN in all patients were identified under laparoscopy, removed, and followed by frozen pathological examination. Pathological ultra-staging was performed if the postoperative pathological outcome of SLN was negative. The total detection rate of SLN, bilateral pelvic SLN detection rate, sensitivity, negative predictive value, and location of SLN in each group were calculated and compared. Results: (1) In 73 patients with endometrial cancer, the overall detection rate of SLN was 88% (64/73), the detection rate of bilateral pelvic SLN was 67% (49/73), and the detection rate of para-aortic SLN was 49% (36/73). The overall detection rate of SLN (71%, 15/21) and bilateral pelvic SLN (43%, 9/21) in the intrauterine injection group were significantly lower than those in the cervical injection group [92% (23/25), 76% (19/25), respectively] and the combined injection group [96% (26/27), 78% (21/27), respectively; all P<0.05]; the detection rate of para-aortic SLN in the cervical injection group (28%, 7/25) was significantly lower than those in the intrauterine injection group and combined injection group [52% (11/21) and 67% (18/27), respectively; both P<0.05]. Among 73 cases with endometrial cancer, 9 had lymph node metastasis confirmed by postoperative pathological examination, 8 of them had lymph node metastasis detected by SLN and 1 had no lymph node metastasis detected by SLN, with a total sensitivity of 89% and a negative predictive value of 98%. The sensitivity and negative predictive value of cervical injection group and combined injection group were 100%, while the sensitivity and negative predictive value of intrauterine injection group were 67% and 95%. Among 56 low-risk patients, only one patient with lymph node metastasis was confirmed by postoperative pathology by SLN detection, and the metastasis rate was 2% (1/56), and the sensitivity and negative predictive value were 100%. Lymph node metastasis was confirmed in 8 of 17 patients (8/17) with a sensitivity of 88% and a negative predictive value of 90%. (2) A total of 459 SLN were detected in 73 endometrial cancer patients, with the highest proportion of external iliac (33.3%, 153/459).The obturator foramen was 25.3% (116/459), para-aortic 19.6% (90/459), iliac 12.0% (55/459), and presacral 9.8% (45/459). The proportion of para-aortic SLN in the cervical injection group was 12.4% (21/169), which were significantly lower than that in the intrauterine injection group and the combined injection group [27.4% (26/95) and 22.1% (43/195), respectively; both P<0.05]. (3) Pathological super-staging results: among 64 patients with negative SLN routine paraffin pathology, 4 cases of lymph node micro-metastases and 1 case of isolated tumor cell metastasis were detected, and the SLN micro-metastases rate was 8% (5/64), including 2 cases of low-risk patients and 3 cases of medium-high risk patients. Conclusions: SLN biopsy has high sensitivity and negative predictive value in patients with early endometrial cancer and could be used as an alternative to systematic lymph node dissection in low-risk patients. The SLN mapping through cervical-uterine combined injection could further improve the detection rate effectively and avoid the missed detection of positive para-aortic lymph node, especially for high-risk patients or patients with fundal tumor involvement.

Abstract
Objective: To construct a diagnostic and predictive model for chronic obstructive pulmonary disease complicated with pulmonary hypertension (COPD-PH) and evaluate its effect. Methods: A total of 1 514 COPD patients treated in 5 hospitals from January 1, 2014 to December 31, 2019 were retrospectively collected and divided into training cohort (1 072 cases) and validation cohort (442 cases) according to the ratio of 7∶3 according to the inclusion time. Data including demographic data, smoking status, history of disease, and clinical examination were collected through patient medical records and electronic medical record systems. Multivariate logistic regression models were used to explore the related factors of COPD-PH, and the nomogram model was constructed using the "rms" program package. The calibration curve was used to evaluate the consistency between the prediction probability of the model and the actual results. The C index and the area under the receiver operating characteristic curve (ROC) were used to evaluate the discrimination of the model. The decision curve analysis (DCA) was used to evaluate the clinical practicability of the model. Results: In the training cohort, 3.7%, 15.2% and 81.1% were aged 50-59, 60-69 and ≥70 years, respectively, which were significantly different from the age composition of the validation cohort (7.9%, 27.8% and 64.3%, respectively) (P=0.041). There was no significant difference between the training cohort (79.4%) and the validation cohort (84.6%) (P=0.243). Multivariate logistic regression analysis of the training cohort showed that age ≥70 years [OR (95%CI): 3.32 (1.49-7.36)] and smoking status [former (current) smoking, OR (95%CI)] were 3.67 (2.51-5.37) and 2.04 (1.44-2.90), respectively], NT-probNP≥1 400 ng/L[OR (95%CI): 9.88 (6.23-15.66)], right atrial diameter [OR (95%CI): 1.11 (1.07-1.15)] was COPD-related factors of PH, based on the above factors-PH nomogram COPD model was set up and develop for online tools (https://ph-666.shinyapps.io/zhonghua-PH/). The calibrated C index (95%CI) of the training cohort and the validation cohort were 0.82 (0.77-0.87) and 0.77 (0.68-0.86), respectively. The calibration curve was close to the diagonal in both the training cohort and the validation cohort. The AUC (95%CI) of the nomogram model was 0.82 (0.80-0.85) in the training cohort and 0.77 (0.73-0.82) in the validation cohort. ROC curve showed that the optimal threshold in the training cohort was 0.60, and the sensitivity and specificity under this value were 0.74 and 0.78, respectively; the optimal threshold for the validation cohort was 0.70, and the sensitivity and specificity under this value were 0.76 and 0.65, respectively. DCA analysis showed that the nomogram model provided better net benefits than the all-variable selection and no-variable selection strategies with threshold probabilities greater than 15.0% and 13.0% in the training and validation cohorts, respectively. Conclusions: The nomogram model for the diagnosis and prediction of COPD-PH is simple and accurate, which has a good clinical application prospect.

Abstract
Calibration-free laser-induced breakdown spectroscopy (CF-LIBS) is a very useful elemental analysis technique. However, it requires knowledge of transition probabilities of the analytical lines. To solve this problem, a variant one-point calibration (OPC) LIBS method was proposed. Quantitative elemental analysis on Cu-Zn-Ag-Au alloys was realized with this method capable of using zinc analytical lines with unknown transition probabilities. The relative error was demonstrated to be less than 3.3%. This variant OPC method will be helpful for quantitative elemental analysis of different samples using CF-LIBS, no matter whether the transition probabilities of the observed lines are known or unknown.

Abstract
Pulmonary arterial hypertension is a progressive pulmonary vascular disease, which can cause right heart failure and even death in severe cases. Treprostinil is a stable prostacyclin analogue and a powerful drug for dilating pulmonary vessels. It can be administered in different ways, with a long half-life, good stability and is suited for diverse types of PAH. It is approved for the treatment of Group 1 PAH, but some studies show that treprostinil is effective in patients with Group 3 or Group 4 PAH. Therefore, this article will review the progress of evidence-based medicine evidence of traprostanil in the treatment of type 1, 3 and 4 pulmonary hypertension.

Abstract
Investigate theclinical practice of seizure prophylaxis after aneurysmal subarachnoid hemorrhage in Chinese neurosurgeons.Aquestionnaire for this theme was designed and was sent to respondents through the internet.From July 2021 to October 2021, atotal of forty-three eligible questionnaires were collected. All responders come from affiliated hospitals of medical schools in China. Each of these hospitals admitted more than one hundred patients with aneurysmal subarachnoid hemorrhage per year. Only 9.3% (4/43) of responders disagree with the prophylactic use of anticonvulsants. 86.04% (37/43) of responders perform seizure prophylaxis in clinical practice. Sodium valproate is the most commonly used regimen; 94.59% (35/37) of responders who perform prophylaxis chose this drug. The medication period differs sharply fromlessthan 3 daystolongerthan 14 daysamong different hospitals. The use of EEG was insufficient in Chinese patients. A low seizure rate was reported according to the feedback from Chinese neurosurgeons.In China, seizure prophylaxis after subarachnoid hemorrhage was not yet standardized. Clinicians' mastery of relevant knowledge is still not enough. Carrying out high-quality clinical research can help justify the use of anticonvulsants, which could also positively impact rational drug use.

Abstract
Chronic thrombotic pulmonary hypertension (CTEPH) is a rare progressive pulmonary vascular disease, which is classified as World Health Organization (WHO) functional class Ⅳ pulmonary arterial hypertension (PAH). The diagnosis was based on mean pulmonary arterial pressure ≥25 mmHg(1 mmHg=0.133 kPa) and pulmonary arterial wedge pressure ≤15 mmHg measured by right heart catheterization, with the under-utilization of radionuclide ventilation/perfusion scan and regular anticoagulation therapy for at least three months. The incidence of CTEPH is low, at 4 cases per million population per year. Despite the in-depth research on CTEPH in recent years, the strengthening of clinical diagnostic awareness, and the emergence of treatment methods such as pulmonary endarterectomy (PEA) and balloon pulmonary angioplasty (BPA), the prognosis of CTEPH patients has been dramatically improved. However, the pathogenesis of CTEPH is unclear, and the lack of effective early diagnostic methods has become a bottleneck limiting the improvement of clinical diagnosis and treatment. In this paper, we reviewed the current research progress on the pathogenesis of CTEPH to increase the understanding of CTPTH disease.

Abstract
Objective: To clarify the impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant on the performance of existing molecular diagnostic assays, and investigate the detection ability of clinical laboratories across China. Methods: The first nationwide external quality assessment (EQA) for molecular detection of Delta variant was carried out based on the non-infectious phage virus-like particles samples, which were prepared by genetic engineering methods and distributed to 8 488 laboratories nationwide. The EQA panel was composed of three Delta variant samples (7.5×102, 1.5×103 and 6.0×103 copies/ml), one non-variant weak positive sample and one negative sample. The percentage of agreement (PA) of Delta variant samples with different concentration, the PA of Delta variant and non-variant samples with 7.5×102 copies/ml, the PA of assays used by more than 100 laboratories for Delta variant samples with different concentration and the PA of Delta variant and non-variant samples with 7.5×102 copies/ml were calculated and analyzed. Results: The data from 8 127 laboratories were available for evaluation. The testing capability of 98.77% (8 027/8 127) of the participating laboratories was found to be competent in reporting correct results for all samples. The overall percentage of agreement (OPA), negative percentage of agreement (NPA) and positive percentage of agreement (PPA) of the samples were 99.64% (40 490/40 635), 99.73% (8 105/8 127), 99.62% (32 385/32 508), respectively. With the decrease of the concentration of the samples, the PPA of Delta variant samples decreased. The PPAs were 99.41% and 99.51% for Delta variant and non-variant samples with 7.5×102 copies/ml, respectively, with no statistical difference (P=0.392). The OPA, NPA and PPA of the assays used by more than 100 laboratories were all greater than 98%, and no statistical difference of the PPAs was identified between Delta variant and non-variant samples with 7.5×102 copies/ml (P>0.05). Conclusions: Delta variant fails to impair the performance of current molecular diagnostic assays in China. The clinical laboratories have the same detection capabilities for Delta variant and non-variant samples. However, in certain laboratories, further improvement is required to ensure the accurate detection of weak positive samples.

Abstract
We investigated a case of cutaneous infection in an immunocompromised patient in China that was caused by a novel species within the Mycobacterium gordonae complex. Results of whole-genome sequencing indicated that some strains considered to be M. gordonae complex are actually polyphyletic and should be designated as closely related species.

Anal Chim Acta 2021; 1179:338839. [PMID: 34535247 DOI: 10.1016/j.aca.2021.338839] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2021] [Revised: 06/18/2021] [Accepted: 07/04/2021] [Indexed: 10/20/2022]
Abstract
N-acylethanolamides (NAEs) are a class of naturally occurring lipid molecules with pleiotropic activities ranging from energy homeostasis to analgesic functioning. However, the comprehensive quantitation of endogenous NAEs is challenged by the sub-trace level (nM) in complex biological samples and the limited availability of stable isotope labeled internal standards (SIL-IS). Herein, a sensitive method was developed to accurately determine 20 NAEs in biological samples by chemical isotope labeling strategy coupled with liquid chromatography - tandem mass spectrometry (LC-MS/MS). A pair of efficient derivatization reagents, acetyl chloride-d0 (ACC-d0) and acetyl chloride-d3 (ACC-d3), were used to label NAEs in biological samples and NAE standard mixture, respectively. The heavily labeled NAE derivatives of the standard substances were used as one-to-one internal standards to minimize the matrix effects and potential ion suppression in MS analysis. Although no chemical moiety with high ionization capability was introduced, the detection sensitivity of the derivatized NAEs were substantially enhanced, as evidenced by 6- to 170-fold increase in LOQs, compared to non-derivatized NAEs. The derivatized NAEs provided the stable and abundant specific product ions in MS/MS spectrum, which were used as the quantitation ions for multiple reaction monitoring (MRM) analysis. The validated LC-MS/MS method was also successfully applied to determine NAEs in serum samples and liver tissues from control and alcohol-fed mice, which shown its practicability in the analysis of endogenous NAE in biological samples. Collectively, the proposed method offers a sensitive and accurate quantification of endogenous NAEs, which may facilitate the understanding of NAE metabolisms and their functions in the physiological and pathological processes.

Abstract
The 17α-hydroxylase/17, 20-lyase deficiency (17-OHD) is a rare disease. The clinical characteristics and gene mutation of 2 late-diagnosed 17-OHD patients with testicular tumor admitted to our hospital from March 2018 to February 2019 were analyzed retrospectively. The two 17-OHD patients were female (46, XY). Laparoscopic abdominal exploration found undeveloped testicles in grey-yellow or grey-red in the groin and iliac fossa. The testicles were removed and showed malignancy in pathology study. Sequencing of the CYP17A1 gene identified c.1247G>A/c.1427T>C and c.985_987delTACinsAA/c.1306G>A complex heterozygous mutations. Taking together, the possibility of 17-OHD should be considered in patients with hypertension, hypokalemia, adrenal adenomatoid hyperplasia together with 46, XY gonadal dysplasia, so as to make early diagnosis and treatment, and avoid dysplastic testicular turning to malignancy.

Abstract
Objective: To investigate the distribution of noise exposure between non-steady state noise and steady-state noise for metal processing workers, which will provide scientific basis for the prevention and treatment of noise hazards in metal processing industry. Methods: The cross-section method was used to investigate the noise exposure of 737 workers from three metal processing industries in Zhejiang Province from October to December 2017. The general demographic information and occupational history were collected by questionnaire. The noise was recorded by individual noise meters, and the noise exposure intensity (equivalent continuous A-weighted noise exposure level normalized to an 8 h-working-day, L(Aeq, 8 h)) and kurtosis were calculated. Results: Workers exposed to noise in the metal processing industry were mainly 18-40 years old (527 workers, 71.51%) , men (570 workers, 77.34%) , and junior high school education background (416 workers, 56.45%) . There were 572 workers (77.61%) with noise exposure intensity (L(Aeq, 8 h)) greater than 85 dB (A) , 558 workers (75.71%) exposed to non-steady state noise (kurtosis ≥4) , and 634 workers (86.02%) with exposure duration less than 8 years. Among the 30 work types investigated, the work types with noise intensity reaching 100% were the stamping, welding and others from a children's car manufacturing factory in Ningbo, operating, chamfering, tapping, and thread rolling from an automobile parts manufacturing factory in Ningbo; The work types with a rate of 100% exposed to non-steady state noise were the grinding from a children's car manufacturing factory in Ningbo, assembling, assembly operating and others from an automobile brake manufacturing factory in Wenzhou, and polishing from an automobile parts manufacturing factory in Ningbo. Conclusion: Metal processing workers have a high rate of over-standard exposed to high noise intensity and a high proportion exposed to non-steady state noise. It is necessary to take sound insulation and noise reduction engineering control, and strengthen personal protection and occupational health management measures to prevent and control the noise hazards.

Abstract
Background Genome-wide association studies (GWASs) have identified some immune-related single-nucleotide polymorphisms (SNPs) to be associated with leprosy. Methods This study investigated the association of 17 SNPs based on previously published GWAS studies with susceptibility to leprosy, different polar forms and immune states of leprosy in a case–control study from southwestern China, including 1344 leprosy patients and 2732 household contacts (HHCs) (1908 relatives and 824 genetically unrelated contact individuals). The differences of allele distributions were analyzed using chi-squared analysis and logistic regression. Results After adjusting covariate factors, rs780668 and rs3764147 polymorphisms influenced susceptibilities to genetically related or unrelated leprosy contact individuals. rs142179458 was associated with onset early cases, rs73058713 A allele and rs3764147 A allele increased the risk of reversal reaction, while rs3764147 G allele had higher risk to present lepromatous leprosy and erythema nodosum leprosum. Conclusion Our results demonstrated that genetic variants in the LACC1, HIF1A, SLC29A3 and CDH18 genes were positively correlated with the occurrence of leprosy and leprosy clinical phenotypes, providing new insights into the immunogenetics of the disease.

Abstract
Objective: To investigate the impact of perioperative anesthesia management with enhanced recovery after surgery (ERAS) strategy on postoperative recovery in patients undergoing laparoscopic surgery for gynecologic malignancy. Methods: Ninety patients undergoing laparoscopic surgery for gynecologic malignancies from April 2018 to April 2019,aged 18-65 years,with American Society of Anesthesiologists (ASA) physical status Ⅰ or Ⅱ, were recruited and randomly divided into two groups (n=45) using a random number table:ERAS group (group E) and control group (group C). Patients in group E received general anesthesia combined with transverses abdominis plane block and a series of interventions to optimize anesthetic and perioperative management, while patients in group C were treated with routine anesthesia management. Quality of Recovery-40 questionnaire (QoR-40) was administered to assess the early postoperative quality of recovery on 1 day before surgery, and at 24 and 48h after surgery. C-reactive protein (CRP) before and after the operation were evaluated. The incidence of nausea, vomiting and shivering, the time of first exhaust, ambulation, resumption of normal diet, postoperative hospital stay and complications were recorded. Results: The scores of QoR-40 [M(Q1, Q3)] in Group E were 175(171, 179) and 185(183, 189) at 24 h and 48 h after operation, which were higher than those in group C [162(160, 167) and 180(179, 183)] (both P<0.01). The levels of CRP in both group E and group C increased at 24 h and 72 h after operation. Moreover, the extent of increasing level of CRP in group C was much higher than that in group E [(39.8±18.0) mg/L vs (13.4±6.3) mg/L, (16.6±8.6) mg/L vs (6.7±2.5) mg/L] at 24 h and 48 h after operation (both P<0.01). Compared with group C, the numerical rating scale (NRS) for nausea decreased significantly in group E [0(0, 2) vs 3 (0, 5), P<0.01]. Meanwhile, the incidence of vomiting and shivering in group E was lower than that in group C [8.9% (4/45) vs 26.7% (12/45); 11.1% (5/45) vs 31.1% (14/45); both P<0.05]. The time of first exhaust, ambulation and resumption of normal diet in group E was (14±6) h, 6(6, 13) h and 1(1, 2) d, respectively, which was markedly shorter than that in group C [(25±10) h, 21(19, 27) h and 3(2, 3) d] (all P<0.01). Overall, the postoperative length of hospital stay reduced significantly for patients who followed the ERAS protocol [7(5, 11) d vs 10(7, 14) d, P<0.01]. The incidence of postoperative complications was 17.8% (8/45) and 37.8% (17/45) in group E and group C, respectively, with a significant difference (P<0.05). Conclusion: Implementation of ERAS anesthesia management in gynecologic oncology patients undergoing minimally invasive surgery alleviates perioperative discomfort, decreases surgical stress response, and improves the early postoperative quality of recovery.
