Objective:To compare the application effects of electric impedance tomography (EIT)-guided positive end-expiratory pressure conventional PEEP and PEEP-fraction of inspired oxygen (FiO 2) table-guided PEEP in the mechanical ventilation of patients with traumatic brain injury (TBI) complicated with acute respiratory distress syndrome (ARDS). Methods:A retrospective cohort study was conducted on the clinical data of 80 TBI patients complicated with ARDS admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from July 2020 to December 2022, including 42 males and 38 females, aged 29-59 years [(42.4±7.8)years]. The Glasgow coma scale (GCS) scores were 3-12 points [(7.7±2.2)points]. According to ARDS classification, 33 were mild, 26 moderate and 21 severe. All the patients were treated with mechanical ventilation according to lung protective ventilation strategy, including 42 patients treated with EIT-guided PEEP (EIT group) and 38 treated with conventional PEEP-FiO 2 table-guided PEEP (conventional group). At 12 hours, 1, 3 and 5 days after ventilation, the optimal PEEP, respiratory mechanics [driving pressure (ΔP), static compliance (C St), mechanical power (MP)], pulmonary gas exchange [arterial blood pH value, arterial partial pressure of carbon dioxide (PaCO 2), oxygenation index (P/F)], ventilation distribution [heterogeneity index (GI), regions of interest (ROI)1-4], hemodynamics [heart rate (HR), central venous pressure (CVP), mean arterial pressure (MAP)], cerebral perfusion status [intracranial pressure (ICP), regional cerebral oxygen saturation (rScO 2) grading], and treatment outcomes (mechanical ventilation duration, incidence of ventilator-induced lung injury (VILI), length of ICU stay, 6-month survival rate) separately at their optimal PEEP were compared between the two groups. Results:All the patients were followed up for 6 months. The optimal PEEP of the EIT group was (7.4±1.0)cm, (8.2±1.2)cm, (9.8±0.8)cm and (8.4±0.7)cm respectively at 12 hours, 1, 3 and 5 days after mechanical ventilation, which were higher than (7.0±1.0)cm, (7.6±1.0)cm, (9.0±0.6)cm and (7.2±0.5)cm of the conventional group ( P<0.05 or 0.01). At their optimal PEEP separately, at 12 hours, 1, 3 and 5 days after treatment, the ΔP of the EIT group was (7.1±1.3)cmH 2O, (7.7±1.3)cmH 2O, (9.5±1.1)cmH 2O and (6.1±1.3)cmH 2O respectively, which were all lower than (8.9±1.3)cmH 2O, (10.5±1.3)cmH 2O, (11.2±1.2)cmH 2O and (8.7±1.2)cmH 2O of the conventional group respectively ( P<0.05 or 0.01); the C St of the EIT group was (51.5±4.2)ml/cmH 2O, (52.9±4.6)ml/cmH 2O, (55.1±4.3)ml/cmH 2O and (57.5±3.6)ml/cmH 2O, which were all higher than (46.8±3.9)ml/cmH 2O, (47.6±4.4)ml/cmH 2O, (49.9±4.3)ml/cmH 2O and (53.3±3.6)ml/cmH 2O of the conventional group respectively ( P<0.05); the MP of the EIT group was (7.9±1.8)J/min, (8.8±1.3)J/min, (10.6±1.3)J/min and (7.8±0.9)J/min, which were lower than (8.6±1.5)J/min, (9.5±1.0)J/min, (12.2±1.8)J/min and (8.6±0.9)J/min of the conventional group respectively ( P<0.05 or 0.01); the P/F of the EIT group was (207.1±7.1)mmHg, (213.1±6.9)mmHg, (239.3±13.1)mmHg and (255.5±11.8)mmHg, which were all higher than (179.6±7.2)mmHg, (187.8±9.6)mmHg, (212.8±9.6)mmHg and (228.1±12.3)mmHg of the conventional group respectively ( P<0.05 or 0.01); the GI of the EIT group were 0.381±0.013, 0.387±0.012, 0.392±0.010 and 0.395±0.010, lower than 0.403±0.005, 0.406±0.005, 0.409±0.005 and 0.411±0.004 of traditional group respectively ( P<0.01); there were no significant differences in the arterial blood pH value, PaCO 2, ROI1-4, HR, CVP, MAP, ICP, or rScO 2 grading between the two groups (P>0.05). The ventilation duration of the EIT group was (78.5±9.0)hours, which was shorter than (83.1±7.4)hours of the conventional group ( P<0.05). The incidence of VILI was 0.0% (0/42) in the EIT group, which was lower than 7.8% (3/38) in the conventional group ( P<0.05). There were no significant differences in the ICU stay or 6-month survival rate between the two groups ( P>0.05). Conclusions:In mechanical ventilation treatment of TBI complicated with ARDS, the optimal PEEP guided by EIT was higher than that guided by PEEP-FiO 2 table. At this optimal PEEP, the respiratory mechanics and oxygen supply of the patients can be improved more effectively, making regional lung ventilation more uniform, reducing the mechanical ventilation time and decreasing the incidence of VILI without affecting their hemodynamics and brain perfusion.

Objective:To explore the economic applicability and safetyof the novel uterovaginal pubic comb suspension(UPCS)surgery with Mersilene tape in the treatment of pelvic organ prolapse(POP).Methods:A ret-rospective analysis was conducted on the clinical data of patients who underwent UPCS surgery due to POP from January 1st,2021 to February 28,2023.They were divided to the UPCS surgery with Mersilene tape group(group A)and suspension surgery with Y-shaped mesh group(group B)respectively.The POP-Q indication points,sus-pension surgery duration,intraoperative bleeding volume,material expense,postoperative catheter retention time,anal exhaust time and hospitalization duration were recorded for both groupbefore and after surgery.Evaluate the severity of POP related symptoms in patients before and after surgery using the pelvic Floor Distress Invento-ry-short Form 20(PFDI-20)and Pelvic Organ Prolapsed/Urinary Incontinence Sexual Questionnaire-12(PISQ-12),and follow up and observe the patients and analyze the complications.Results:A total of 17 POP patients were included in the study.There were 12 patients in group A while 5 patients in group B.The suspension material expense of group A was considerably lower than that of group B(P＜0.05).There was no significant difference between the two groups in preoperative PFDI-20 score,preoperative PISQ-12 score,UPCS surgery duration,intr-aoperative bleeding volume,postoperative urinary catheter retention time,postoperative anal exhaust time and hospitalization duration.All patients showed stable vital signs during the surgery and no severe complications were reported.Compared with the preoperative status,the positions of the Aa,Ba,and C indicatorpoint in group A and group B were all increased significantly(P＜0.05).The PFDl-20 and PISQ-12 scores of the two groups at the last follow-up after surgery showed significant improvement compared to those before surgery(P＜0.05).No signifi-cant difference was found in the PFDI-20 and PISQ-12 scores between the two groups after surgery(P＞0.05).There were no significant differences in the postoperative complications between the two groups(P＞0.05).Con-clusions:Compared with suspension surgery with Y-shaped mesh,UPCS surgery with Mersilene tape is safe and effective in the treatment of POP.The UPCS surgery with Mersilene tape showed better cost-effectiveness in the treatment of POP,and the surgical steps are relatively simple.Therefore,UPCS surgery with Mersilene tape was worthy of promotion in clinical practice.

Objective:To investigate the clinical value of early gastroscopy for patients with hypopharyngeal cancer.Methods:A total of 231 cases of hypopharyngeal cancer diagnosed and treated in the First Affiliated Hospital of Xiamen University from January 2010 to December 2014 were included in the retrospective analysis. The 5-year survival rate of hypopharyngeal cancer and patients accompanied with synchronous esophageal cancer (including early and advanced esophageal cancer), as well as the detection rate of synchronous esophageal cancer by gastroscopy and systemic PET-CT examination were statistically analyzed.Results:The 5-year survival rate of hypopharyngeal cancer was 38.96% (90/231). The 5-year survival rates of 62 patients accompanied with synchronous esophageal cancer and 169 patients without were 27.42% (17/62) and 43.20% (73/169), respectively, with statistic difference ( χ2=4.747, P=0.029). The 5-year survival rate of 49 patients accompanied with synchronous early esophageal cancer was 30.69% (17/49). Among the 13 patients with synchronous progressive esophageal cancer, none had a survival period of 5 years, which was significantly different compared with the patients with synchronous early esophageal cancer ( P=0.013). The detection rates of synchronous esophageal carcinoma by gastroscopy and by systemic PET-CT were 26.84% (62/231) and 14.29% (33/231), respectively, with statistic difference ( χ2=11.14, P<0.01). The detection rates of synchronous early esophageal carcinoma by gastroscopy and by systemic PET-CT were 21.21% (49/231) and 8.66% (20/231), respectively, and the difference was also statistically significant ( χ2=14.328, P<0.01). Conclusion:Hypopharyngeal cancer accompanied with synchronous esophageal cancer is of high risk, which affects the survival rate of patients. Early gastroscopy in hypopharyngeal cancer patients can significantly improve the detection rate of synchronous esophageal cancer, which helps to design individualized regimen to improve the survival rate of patients.

Objective:To observe the changes of nutrition impact symptoms (NIS) and fat-free mass and analyze the relationship between them in patients with head and neck cancer (HNC) during radiotherapy.Methods:A convenient sampling method was adopted to select HNC patients who received radiotherapy in the outpatient clinic of department of radiotherapy for head and neck cancer in a cancer hospital in Beijing from March 2017 to January 2020. The nutrition impact symptoms (NIS) were assessed by a nutrition impact symptoms checklist and the fat free mass was assessed by bioelectrical impedance analysis at three time points: before radiotherapy (T1), during radiotherapy (T2) and at the end of radiotherapy (T3). The Generalized Estimating Equations (GEE) was used to analyze the relationship between them.Results:A total of 542 HNC patients were included in the analysis. During radiotherapy, the patients' NIS number and score presented an increasing trend, reaching the highest level and peaked at the end of radiotherapy. The change of fat-free mass showed a decreasing trend and reached the minimum at the end of radiotherapy. Patients with higher NIS scores had more percentage loss of fat-free mass.Conclusions:During radiotherapy, patients with HNC showed an increase in NIS score and lost fat-free mass. Patients with higher NIS score lost more percentage of fat-free mass, which suggested that clinical medical staff should pay attention to NIS management and take comprehensive intervention measures in time to reduce the loss of fat-free mass.

Obesity has become a major public health problem that threatens human health.Abdominal obesity, especially the increase in visceral adipose tissue(VAT), can in some cases lead to insulin resistance and other metabolism-related diseases such as diabetes, cardiovascular disease, thrombosis, and pro-inflammatory metabolic abnormalities.Metabolic syndrome is a group of clinical syndromes characterized by the co-occurrence of various metabolic diseases, including insulin resistance and inflammatory response.In a large extent, the occurrence and development of the metabolic syndrome are related to fat aging and visceral obesity related.Visceral obesity is an independent risk factor for cardiovascular events, and can be changed, so by setting realistic goals, by insisting on reasonable exercise and diet control can achieve control of visceral fat, prevention and control of the metabolic syndrome.This review reviews the concept and pathophysiology of metabolic syndrome and the relationship between visceral obesity and metabolic syndrome.

Objective:To study the efficacy of dental floss traction-assisted endoscopic submucosal dissection (ESD) for gastric angle mucosal lesions.Methods:Data of 127 patients with gastric angle mucosal lesions admitted to the endoscopic center of the First Affiliated Hospital of Xiamen University from January 2015 to December 2018 were retrospectively analyzed. According to the surgical methods, patients were divided into the dental floss traction-assisted ESD group (the traction group, n=51) and the traditional ESD group (the traditional group, n=76). The 41 fibrosis cases were further divided into the traction group (n=23) and the traditional group (n=18). The operation time, en block resection rate, curative resection rate and the incidence of adverse events such as bleeding, muscle layer injury and perforation were compared between the two groups.Results:There was no significant difference in age, sex, lesion size or morphology between the traction group and the traditional group ( P > 0.05). The operation time of the traction group was significantly shorter than that of the traditional group (65.4±36.5 min VS 103.5±43.2 min, P=0.012). The en block resection rate was higher in the traction group [100.00% (51/51) VS 90.79% (69/76), P=0.026], and the curative resection rate was higher too [94.12% (48/51) VS 81.58% (62/76), P=0.042]. The incidences of muscular layer damage [5.88% (3/51) VS 25.00% (19/76), P=0.010] and intraoperative bleeding [47.06% (24/51)VS 82.89% (63/76), P=0.010] were lower in the traction group. Perforation occurred in two patients (2.63%) of fibrosis in the traditional group; no perforation occurred in the traction group. There was no significant difference in the perforation incidence ( P=0.243). In the cases of fibrosis, the operation time of the traction group was significantly shorter compared with that of the traditional group (81.4±29.3 min VS 119.3±37.6 min, P=0.010). The en block resection rate and curative resection rate were also higher in the traction group [100.00% (23/23) VS 72.22% (13/18), P=0.007; 95.65% (22/23) VS 72.22% (13/18), P=0.035]. The incidences of muscular layer damage [8.70% (2/23) VS 72.22% (13/18), P=0.001] and intraoperative bleeding [78.26% (18/23) VS 100.00% (18/18), P=0.035] were lower in the traction group. Conclusion:The dental floss traction-assisted ESD is safe and effective for gastric angle mucosal lesions and fibrotic lesions, with shorter operation time, higher curative resection rate and lower incidence of adverse events.
