ABSTRACT
Background/Aims@#The accuracy of endosonographers in diagnosing gastric subepithelial lesions (SELs) using endoscopic ultrasonography (EUS) is influenced by experience and subjectivity. Artificial intelligence (AI) has achieved remarkable development in this field. This study aimed to develop an AI-based EUS diagnostic model for the diagnosis of SELs, and evaluated its efficacy with external validation. @*Methods@#We developed the EUS-AI model with ResNeSt50 using EUS images from two hospitals to predict the histopathology of the gastric SELs originating from muscularis propria. The diagnostic performance of the model was also validated using EUS images obtained from four other hospitals. @*Results@#A total of 2,057 images from 367 patients (375 SELs) were chosen to build the models, and 914 images from 106 patients (108 SELs) were chosen for external validation. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the model for differentiating gastrointestinal stromal tumors (GISTs) and non-GISTs in the external validation sets by images were 82.01%, 68.22%, 86.77%, 59.86%, and 78.12%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the external validation set by tumors were 83.75%, 71.43%, 89.33%, 60.61%, and 80.56%, respectively. The EUS-AI model showed better performance (especially specificity) than some endosonographers.The model helped improve the sensitivity, specificity, and accuracy of certain endosonographers. @*Conclusions@#We developed an EUS-AI model to classify gastric SELs originating from muscularis propria into GISTs and non-GISTs with good accuracy. The model may help improve the diagnostic performance of endosonographers. Further work is required to develop a multi-modal EUS-AI system.
ABSTRACT
Objective:To explore the effect of spontaneous breathing during induction of general anesthesia on atelectasis in patients undergoing laparoscopic resection of gastrointestinal tumors.Methods:A total of 60 patients aged 18-60 years scheduled for laparoscopic resection of gastrointestinal tumors under general anesthesia in the First Hospital of Shanxi Medical University from October 2021 to August 2022 were selected. The body mass index was 18.5-28.0 kg/m 2 and the American Society of Anesthesiology grade wasⅠ-Ⅱ. All patients were divided into the spontaneous breathing group (group S, 30 cases) and the controlled breathing group (group C, 30 cases) according to the random number table method. Patients in group S received 0.2-0.3 mg/kg etomidate (pumping at the speed of 200 ml/h) and 2 μg/kg remifentanil (slowly injected more than 30 s) for anesthesia induction; patients in group C received 0.2-0.3 mg/kg etomidate and 2 μg/kg remifentanil (slowly injected more than 30 s) and 0.2 mg/kg cisatracurium. After bispectral index (BIS) decreased to 80, the patients had no response to the language stimulation; and then the mask was used to closely fit the face and maintain spontaneous breathing in group S; patients in group C received manual positive pressure ventilation. Atelectasis scores were collected immediately after endotracheal intubation (T 1) and 15 min after transferring to the recovery room (T 3), and oxygenation index (OI) was collected 5 min after endotracheal intubation (T 2) and at T 3. The postoperative pulmonary complication (PPC) on the 3rd day after the operation was recorded. Results:A total of 56 patients were finally enrolled, 27 cases in group S and 29 cases in groups C. Compared with group C, the atelectasis score of group S at T 1 and T 3 decreased [T 1: (2.4±0.8) scores vs. (4.2±0.7) scores, t = -9.12, P < 0.001; T 3: (8.2±1.8) scores vs. (10.5±1.6) scores, t = -4.96, P < 0.001]. The OI increased at T 2 and T 3 in group S [T 2: (334±11) mmHg (1 mmHg = 0.133 kPa) vs. (323±13) mmHg, t = 3.45, P = 0.001; T 3: (362±23) mmHg vs. (347±25) mmHg, t = 2.31, P = 0.025]. The incidence of PPC was 20.7% (6/29) and 18.5% (5/27), respectively in group C and group S on the 3rd day after the operation, and the difference was statistically significant ( χ2 = 0.04, P = 0.838). Conclusions:Maintaining spontaneous breathing during induction of general anesthesia can reduce atelectasis caused by general anesthesia and improve oxygenation for patients undergoing laparoscopic resection of gastrointestinal tumors.
ABSTRACT
Objective:To explore the cost-effectiveness of alfacalcidol and cinacalcet for the treatment of secondary hyperparathyroidism in dialysis patients compared with parathyroidectomy.Methods:A total of 60 patients with secondary hyperparathyroidism treated at the Third People's Hospital of Chengdu from 2011 to 2020 were studied, patients were randomly divided into three groups: cinacalcet group, alfacalcidol group and parathyroidectomy group, with 20 cases in each group.Result:The improvement rate of bone pain and skin pruritis in parathyroidectomy group were higher than that in cinacalcet group and alfacalcidol group ( χ2=16.282, P<0.001; χ2=12.823, P=0.002). After 12 months of treatment, iPTH in the parathyroidectomy group and the cinacalcet group was significantly lower than that in the alfacalcidol group ( HR=1.36, 95% CI: 1.00-1.72, P<0.001; HR=1.27, 95% CI: 0.91-1.63, P<0.001); Serum calcium in the parathyroidectomy group was significantly lower than that of the other two groups ( HR=0.18, 95% CI: 0.12-0.24, P<0.001; HR=0.14, 95% CI: 0.08-0.20, P<0.001). The cost of complications management in the parathyroidectomy group was the lowest ( H=40.534, P<0.001), with bone pain being the most cost concern ( H=38.494, P<0.001). Patients with iPTH>2 800 pg/ml had the highest costs than with 800~1 800/ml and 1 800~2 800/ml ( H=43.798, 37.260, P<0.001). Conclusion:Surgical treatment should be the first choice for patients with secondary hyperparathyroidism, especially for patients with iPTH>2 800 pg/ml and bone pain.
ABSTRACT
Objective:To evaluate the effect of continuous positive airway pressure(CPAP) ventilation strategy during induction of general anesthesia on atelectasis after induction in obese patients.Methods:A total of 86 patients, aged 30-60 yr, with body mass index of 28-35 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱor Ⅲ, scheduled for elective cerebrovascular intervention under general anesthesia, were divided into 2 groups ( n=43 each) using a random number table method: CPAP group (group C) and routine group (group R). Group C received CPAP 5 cmH 2O-assisted ventilation after preoxygenation for spontaneous breathing and disappearance of spontaneous breathing. Chest CT scan and arterial blood gas analysis were performed after entering the operating room (T 1) and 5 min after endotracheal intubation (T 2) to calculate the percentage of atelectasis area and to record PaO 2. Dynamic lung compliance and plateau pressure were recorded at T 2. Mean minute ventilation under controlled breathing, P ETCO 2, and use of vasoactive drugs during induction were recorded. The occurrence of reflux and aspiration during mask ventilation was recorded. The development of pulmonary complications within 3 days after operation was recorded. Results:Compared with group R, the percentage of atelectasis area at T 2 was significantly decreased, PaO 2, dynamic lung compliance and plateau pressure were increased ( P<0.05), and no significant change was found in mean minute ventilation, P ETCO 2, requirement for vasoactive drugs and incidence of pulmonary complications in group C ( P>0.05). No reflux or aspiration was observed during mask ventilation. Conclusions:CPAP (5 cmH 2O) strategy during anesthesia induction can reduce the degree of atelectasis after induction in obese patients.
ABSTRACT
Objective:To evaluate the effect of continuous positive airway pressure (CPAP) ventilation during induction of anesthesia on perioperative atelectasis and oxygenation in elderly patients.Methods:Forty-six elderly patients of either sex, aged 65-80 yr, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, undergoing elective cerebrovascular intervention surgery under general anesthesia, were divided into 2 groups ( n=23 each) according to the random number table method: control group (group C) and CPAP ventilation group (group CPAP). During induction of anesthesia, CPAP was set at 5 cmH 2O during spontaneous breathing, and PEEP was set at 5 cmH 2O when spontaneous breathing disappeared, and the ventilation mode was changed to pressure-controlled ventilation (PCV) mode in group CPAP. CPAP was not set, and PEEP was set at 0 cmH 2O for PCV when spontaneous breathing disappeared in group C. During anesthesia maintenance, PCV-volume guaranteed mode was used in both groups, and PEEP was set at 5 cmH 2O. Whole lung CT scanning was performed immediately after radial artery catheterization (T 0), at 1 min after endotracheal intubation (T 1), and before tracheal extubation (T 2) at the end of operation to calculate the percentage of atelectasis area at 1 cm above the right diaphragm. At T 0, T 1, T 2 and 30 min after entering postanesthesia care unit (T 3), blood samples from the radial artery were taken to record PaO 2 and PaCO 2 and calculate the oxygenation index (OI). Results:Compared with the baseline at T 0, the percentage of atelectasis area was significantly increased at T 1 and T 2 in two groups ( P<0.05); PaO 2 was significantly increased at T 1 and T 2 and decreased to T 0 level at T 3, OI was decreased at T 1 and T 2 and increased to T 0 level at T 3 in two groups ( P<0.05). Compared with group C, the percentage of atelectasis area was significantly decreased and PaO 2 and OI were increased at T 1 and T 2 in group CPAP ( P<0.05). There was no significant difference in PaCO 2 at each time point between the two groups ( P>0.05). Conclusions:CPAP ventilation during induction of anesthesia can reduce the development of perioperative atelectasis and improve the oxygenation in elderly patients.

The numerical rating scale(NRS)scores were observed and recorded 1 day before surgery, 6, 12, 24, and 48 hours after surgery; the time of the first active straight leg raising after surgery, the time of landing; the range of motion(ROM)of the knee joint 3, 7, and 14 days after surgery; the American Hospital for Special Surgery Knee Score(HSS)at 14 days, 1, 3, and 6 months after surgery; serum substance P(SP)and interleukin-6(IL-6)concentrations 1 day before surgery and 48 hours after surgery, and adverse events were recorded.Results:Compared with the control group, the patients in the observation group had lower NRS scores at 6, 12, 24, and 48 hours after the operation( t=27.705, 27.532, 21.739, 25.780, all P<0.05); the first active straight leg raising time and the time of landing earlier after the operation, and the knee joint at 3, 7, and 14 days after the operation, the range of motion(ROM)was better( t=35.496, 43.716, 3.766, 5.216, 6.009, all P<0.05). And the American hospital for special surgery knee score(HSS)was higher at 14 days, 1 month, and 3 months after surgery( t=19.247, 32.337, 22.651, all P<0.05), but there was no significant difference at 6 months after surgery.Simultaneously, the serum SP and IL-6 concentrations in the observation group 48 h after the operation were (431.0±11.3)ng/L and(11.9±2.7)ng/L, respectively.Compared with the control group(442.5±15.6)ng/L, (14.4±2.9)ng/L( t=5.362, 4.144, both P<0.05). Compared with the control group, which were lower than those in the incidence of postoperative nausea and vomiting was lower, the length of hospital stay was shorter in the observation group( χ2=4.630, t=3.311, P=0.031, 0.002), and the other indicators had no statistical differences(all P>0.05). Conclusions:Multimodal low-opioid combined with saphenous nerve block analgesia can significantly reduce perioperative pain in elderly patients undergoing knee arthroplasty, improve early postoperative mobility, and speed up postoperative functional recovery.
ABSTRACT
Objective To evaluate the role and potential mechanism of interleukin (IL)-18/IL-18 binding protein (BP) in mediating the killing effect of natural killer (NK)-92MI cells upon endothelial cells from α-1, 3- galactosyltransferase gene-knockout (GTKO) porcine models. Methods NK-92MI cells were divided into the NK, NK+IL-18, NK+GTKO, IL-18+NK+GTKO and IL-18+IL-18BP+NK+GTKO groups. The messenger ribonucleic acid (mRNA) levels of inflammation-related genes in NK-92MI cells were detected by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). The killing effect of NK-92MI cells on endothelial cells from GTKO porcine models was evaluated by lactate dehydrogenase (LDH) assay. The apoptosis of endothelial cells from GTKO porcine models was assessed by terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. The expression levels of proteins with killing effect and apoptosis-related proteins were determined by Western blot. Results Compared with the NK, NK+IL-18 and NK+GTKO groups, the expression levels of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, IL-8, IL-3, IL-6 and granulocyte-macrophage colony stimulating factor (GM-CSF) mRNA were up-regulated in NK-92MI cells in the IL-18+NK+GTKO group, and the differences were statistically significant (all P < 0.05). Compared with the IL-18+NK+GTKO group, the expression levels of IFN-γ, TNF-α, IL-8, IL-3, IL-6 and GM-CSF mRNA were down-regulated in NK-92MI cells in the IL-18+IL-18BP+NK+GTKO group, and the differences were statistically significant (all P < 0.05). Compared with the NK+GTKO group, the expression levels of perforin, granzyme B and IFN-γ proteins in NK-92MI cells were up-regulated, the killing rate of NK-92MI cells against endothelial cells from GTKO porcine models was enhanced, the apoptosis rate of endothelial cells from GTKO porcine models was increased, and the ratios of B cell lymphoma-2 (Bcl-2)-associated X protein (Bax)/Bcl-2 and cleaved Caspase-3/Caspase-3 in endothelial cells from GTKO porcine models were elevated in the IL-18+NK+GTKO group, and the differences were statistically significant (all P < 0.05). Compared with the IL-18+NK+GTKO group, the expression levels of perforin, granzyme B and IFN-γ proteins were down-regulated, the killing rate of NK-92MI cells against endothelial cells from GTKO porcine models was decreased, the apoptosis rate of endothelial cells from GTKO porcine models was decreased, and the ratios of Bax/Bcl-2 and cleaved Caspase-3/Caspase-3 in endothelial cells from GTKO porcine models were declined in the IL-18+IL-18BP+NK+GTKO group, and the differences were statistically significant (all P < 0.05). Conclusions IL-18BP may block the expression of inflammation-related genes in NK-92MI cells induced by IL-18 and the killing effect of NK-92MI cells on endothelial cells from GTKO porcine models.

ABSTRACT
Objective:To report pediatric endoscopic retrograde cholangiopancreatography (ERCP) intubation techniques and to analyze the influencing factors of pediatric ERCP in China.Methods:Retrospective analysis was performed on 90 cases of pediatric and adult ERCP operations respectively at Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2016 to June 2020. The anatomic data, intubation time, and endoscopic intubation measures were reviewed. The anatomic differences in duodenal papilla between the children and adults were analyzed to find the factors affecting ERCP intubation time in children.Results:There were 88 cases of successful infantile intubation with the success rate of 97.8%, and 90 cases of successful adult intubation with the success rate of 100.0%. The intubation time in the pediatric group was 187±67 s, and that in the adult group was 247±86 s with significant difference ( t=5.220, P<0.001). The duodenal diameter of pediatric patients was 3.38±1.57 cm, and that of adult patients was 5.94±1.87 cm with significant difference ( t=9.832, P<0.001). The horizontal distance from the duodenal bulb to the papilla in pediatric patients was 2.44±1.15 cm, which was significantly shorter than 4.22±1.43 cm in adult patients ( t=9.077, P<0.001). Most duodenal papillae in children were hemispherical [flat 26.1% (23/88), hemispherical 51.1% (45/88), cylindrical 22.7% (20/88)], while most of those in the adult patients were cylindrical [flat 9.1% (8/88), hemispherical 23.9% (21/88), cylindrical 67.0% (59/88)]. The factors influencing the intubation time of ERCP in children by univariate analysis included the shape of duodenal papilla, duodenal papilla hardness, visual region, distance from junction of duodenal bulb and descending part to duodenal papilla, distance from duodenal papilla to endoscope, and degree of incising. Conclusion:Shorter and stiffer duodenal papillae in children with normal papilla orientation are associated with shorter intubation time. These indicators are favorable factors for intubation.
ABSTRACT
Objective:To explore the risk factors involved in gastritis, gastric intraepithelial neoplasia (GIN) and gastric cancer in Shihezi area.Methods:A total of 7 110 Han nationality patients who underwent gastroscopy at the First Affiliated Hospital of Shihezi University School of Medicine from January 2012 to December 2016 were selected as the research subjects. The data of patients were obtained through medical records and questionnaires. After excluding diseases related to esophagus and duodenum, a total of 4 429 cases were included in the retrospective analysis. Of which, 4 249 were gastritis, 93 were GIN, and 87 were gastric cancer. χ2 test, rank-sum test or Fisher exact probability method were used to analyze the differences of various factors in gastritis, GIN and gastric cancer. Univariate and multivariate logistic regression analysis were used to screen the risk factors for gastritis progression to GIN and gastric cancer. Results:χ2 test and rank sum test showed that there were statistically significant differences in gender, age, history of digestive diseases and distribution of Helicobacter pylori ( HP) infection among the groups of gastritis, GIN and gastric cancer ( P<0.05). The proportion of HP infection decreased gradually with the disease severity. Multivariate logistic regression analysis showed that male ( P<0.001, OR=2.251, 95% CI: 1.461-3.470), elderly ( P<0.001, OR=4.829, 95% CI: 2.241-10.409), a family history of gastric cancer ( P=0.002, OR=3.227, 95% CI: 1.537-6.774) and a history of digestive diseases ( P=0.034, OR=1.644, 95% CI: 1.037-2.607) were independent risk factors for gastritis progression to GIN. Male ( P<0.001, OR=3.254, 95% CI: 2.026-5.225), middle-aged ( P=0.022, OR=2.688, 95% CI: 1.153-6.265) and elderly ( P=0.002, OR=4.734, 95% CI: 1.750-12.807) were independent risk factors for gastritis progression to gastric cancer. In stratified analysis to exclude age and gender, smoking ( P=0.028, OR=4.060, 95% CI: 1.160-14.202) was found to be a risk factor for gastritis progression to GIN in young adults, and obesity ( P=0.032, OR=3.869, 95% CI: 1.121-13.356) was found to be a risk factor for gastritis progression to gastric cancer in women. Conclusion:The degree of HP infection in gastric tissues is negatively correlated with the severity of gastric diseases, suggesting that HP infection may be an early event inducing gastric cancer. Male, the elderly, people with a family history of gastric cancer and a history of digestive diseases, and young smokers in Shihezi are more likely to develop GIN, and male, middle-aged, elderly, and obese women are at increased risk of gastric cancer.

ABSTRACT
BACKGROUND@#Primary lung squamous carcinoma that produces alpha-fetoprotein (AFP) is rare and only four related cases have been reported so far. The specific reasons for elevated serum level of AFP and effective treatment regimens for AFP-producing lung squamous carcinoma are not clear. This paper reports the diagnosis and treatment of AFP-producing lung squamous carcinoma so as to provide some references for similar cases in clinical practice.@*METHODS@#The diagnosis and treatment of an AFP-producing lung squamous carcinoma patient admitted to the Shandong Cancer Hospital on October 23, 2020 was retrospectively analyzed, and literatures were reviewed.@*RESULTS@#A 52-year-old male patient was diagnosed as T4N3M0 stage, IIIc right upper lobe lung squamous cell carcinoma with mediastinal lymph node metastasis and multiple metastases in the lung. The main tumor marker was abnormally increased serum AFP. After the rapid progression of two lines chemotherapy, the patient was given anlotinib combined with carrizumab as third-line treatment. The efficacy evaluation reached to partial response (PR) and stable disease (SD) after 2 and 4 cycles of treatment, respectively. The treatment regimen was replaced with albumin paclitaxel plus carrizumab due to gastrointestinal bleeding after the fifth cycle. The patient's condition was under continuous control.@*CONCLUSIONS@#The AFP-producing lung squamous carcinoma patient had a good response to anlotinib and immunotherapy in the case report, which may provide some guidances for the clinical practice and the research on AFP-producing lung squamous carcinoma.

Objective:To seek indicators or models for predicting the risk of deep vein thrombosis (DVT) after traumatic lower extremity fractures.Methods:A nested case-control study was conducted on 424 patients with traumatic lower extremity fractures in Beijing Jishuitan Hospital from May 2019 to December 2019. Patients with traumatic lower extremity fractures of the hip, femoral shaft, distal femoral, patella, tibial plateau, tibiofibular shaft, ankle or foot were 18 or older. Trauma patients were examined by venogram before surgery. 56 of 424 patients with traumatic lower limb fractures were diagnosed with preoperative DVT. Then, those with no evidence of DVT were paired by age, gender and fracture sites to those with DVT. Laboratory parameters included conventional coagulation tests and thrombotic biomarkers, such as D-dimer, plasmin-ɑ2-plasmin inhibitor complex (PIC), tissue plasminogen activator-plasminogen activator inhibitor complex (tPAIC), and Caprini score was calculated. Univariate analysis was used to distinguish statistically significant variables between trauma patients with and without DVT. Then logistic regression analysis was applied to identify independent risk factors for post-traumatic DVT. The receiver-operating characteristic (ROC) curve analysis was employed to assess the efficacy of indicators in predicting the risk of DVT after traumatic lower extremity fractures.Results:The levels of tPAIC and Caprini score in patients with DVT after traumatic lower limb fractures were significantly higher than those in non-DVT patients ( P values of 0.036 and 0.016, respectively). D-dimer, PIC, and Caprini score were independent risk factors for preoperative DVT after traumatic lower limb fractures. Thus, we defined the Predicting Index as 0.098×D-dimer (mg/L FEU)+(-0.564) ×PIC (μg/ml)+0.233×Caprini score, and found that the area under the ROC curve for the Predicting Index was 0.721. Conclusions:Predicting Index, calculated by D-dimer, PIC and Caprini score, can comprehensively encompass the changes of risk factors between patients with and without DVT after traumatic lower limb fractures, and can well predict the risk of DVT after traumatic lower extremity fractures.
ABSTRACT
Objective:To investigate the relationships between severe, diffuse decrease in global brain 18F-fluorodeoxxglucose(FDG)uptake, whole-body total lesion glycolysis(TLG)and short-term death in elderly patients with newly diagnosed stage Ⅳ cancer. Methods:Clinical and 18FFDG PET/CT data of 24 elderly patients newly diagnosed stage Ⅳ cancer showing marked diffuse decrease in global brain FDG uptake(the decreased brain uptake group)were retrospectively enrolled.Sixteen elderly patients with newly diagnosed stage Ⅳ cancer but without decreased global brain FDG uptake(the no decreased brain uptake group)and 25 healthy subjects were enrolled as the control groups.Correlations between brain FDG uptake and whole-body TLG were analyzed.We followed up the final outcomes of all patients and analyzed the short-term prognostic value of these manifestations. Results:The decreased brain uptake group included 17 patients with stage Ⅳ lymphoma and 7 patients with stage Ⅳ malignant tumor of other types[15 males, age: (73±9)years], while the no decreased brain uptake group included 8 patients with stage Ⅳ lymphoma and 8 patients with stage Ⅳ malignant tumor of other types[12 males, age: (65±5)years]and the healthy control group included 25 subjects[13 males, age: (65±6)years]. Patients were older in the decreased brain uptake group than in the no decreased brain uptake group( t=3.8, P=0.001). The global brain SUV means of the decreased brain uptake group and the no decreased brain uptake group were 4.9±1.8 and 10.9±2.0, respectively( t=-9.8, P=0.000). The global brain total glycolysis(TG)values of the two groups were 1786.5±1162.5 and 2868.4±1424.5, respectively( t=-2.6, P=0.012). The whole-body TLG values of the two groups were 6825.5±4776.9 and 2919.5±2031.7, respectively( t=3.6, P=0.001). Pearson correlation analysis showed that brain FDG uptake was adversely correlated with whole-body TLG.We followed up the survival outcomes of the two groups.The median follow-up lengths of the two groups were 6 months and 10 months, respectively( χ2=3.7, P=0.054). Fourteen(14/24)patients died in the decreased brain uptake group while 9(9/16)died in the no decreased brain uptake group( χ2=0.017, P=0.896). However, 8 cases died within 1 month post PET/CT scan in the decreased brain uptake group while none died in the no decreased brain uptake group( χ2=4.7, P=0.029). Conclusions:Severe, diffuse decrease in 18F-FDG PET/CT uptake in the whole cerebral cortex is more common in elderly patients with newly diagnosed stage Ⅳ cancer, whose total tumor load is significantly higher than that of cancer patients without decrease in whole cerebral cortex FDG uptake.This uptake reduction may indicate poor short-term outcome and the probability of short-term death may be high.
ABSTRACT
Objective:To evaluate the effect of driving pressure-guided individualized positive end-expiratory pressure (PEEP) titration on atelectasis in elderly patients undergoing robot-assisted radical prostatectomy.Methods:Fifty elderly patients, aged 65-80 yr, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, with body mass index of 19-28 kg/m 2, undergoing elective robot-assisted radical prostatectomy under general anesthesia, were divided into 2 groups ( n=25 each) according to the random number table method: traditional lung-protective ventilation group (group C) and driving pressure-guided individualized PEEP group (group D). The method for setting PEEP was as follows: PEEP 5 cmH 2O was used throughout operation in group C. In group D, the optimal PEEP was titrated after intubation and mechanical ventilation and Trendelenburg position-pneumoperitoneum construction, the initial value was the lowest PEEP allowed by the anesthesia machine, the PEEP was increased by 1 cmH 2O (PEEP≤12 cmH 2O) every 4 min, the plateau pressure and PEEP were simultaneously recorded to calculate the driving pressure, and the corresponding PEEP was considered as the optimal PEEP for the individual when the driving pressure reached the minimum.Ultrasound examination was performed after catheterization of radial artery (T 0), after anesthesia induction (T 1), 4 min after developing optimal PEEP ventilation (T 2, 4 min after developing ventilation in group C), after restoration of body position (T 3), before extubation (T 4), and at 2 h after admission to postanesthesia care unit (T 5). Atelectatic aeration loss scores were recorded at T 0, T 1, T 4 and T 5.Bilateral optic nerve sheath diameter was measured at T 0-4.Arterial blood gas analysis was performed at T 0, T 2, T 3 and T 5, PaO 2 and PaCO 2 were recorded, and oxygenation index was calculated.The postoperative pulmonary complications within 3 days after operation were recorded. Results:Compared with group C, atelectasis aeration loss scores at T 4, 5 and PaCO 2 at T 2, 3 were significantly decreased, and PaO 2 and oxygenation index were increased at T 2, 3, 5 in group D ( P<0.05). There were no significant differences in the bilateral optic nerve sheath diameter and incidence of postoperative pulmonary complications between the two groups ( P>0.05). Conclusion:Driving pressure-guided individualized PEEP can increase intraoperative oxygenation and decrease the development of atelectasis in elderly patients undergoing robot-assisted radical prostatectomy.
ABSTRACT
BACKGROUND@#Programmed cell death 1 or programmed cell death ligand 1 inhibitor (PD-1/PD-L1 inhibitor) and docetaxel, as the standard second-line treatments of advanced non-small cell lung cancer (NSCLC) patients, have limited effects. There are few studies on whether docetaxel combined with PD-1/PD-L1 inhibitor can increase the efficacy and make patients better benefit. The aim of this study is to evaluate the efficacy and safety of docetaxel combined with PD-1/PD-L1 inhibitor for the second-line treatment of stage IV NSCLC patients.@*METHODS@#Stage IV NSCLC patients (n=118) who received treatment at Shandong Cancer Hospital between October 1, 2018, and December 31, 2020, were retrospectively analyzed. They were divided into observation group (n=69) and control group (n=49) according to different treatment plan. Observation group was given docetaxel plus PD-1/PD-L1 inhibitor, while control group was given PD-1/PD-L1 inhibitor. The clinical curative effect and the incidence of adverse reactions of grade 3 and above were compared between the two groups.@*RESULTS@#The disease control rate (DCR) was higher in the observation group (89.9%) than that in the control group (73.5%) (P=0.019), and the objective response rate (ORR) showed no significant difference between observation group (24.6%) and control group (16.3%) (P=0.276). Till June 22, 2021, the 1-year PFS rate showed no difference between observation group (16.5%) and control group (7.7%) (P=0.205). During the treatment period, the adverse reactions of the two groups were mostly grade 1 to 2, and could be tolerated. The incidence of bone marrow suppression in observation group was higher than that in the control group (P<0.05), and the remaining adverse reactions were not statistically different from control group. Cox regression analysis showed that performance status (PS) (P=0.020) and age (P=0.049) were independent prognostic factors for the effect of docetaxel combined with PD-1/PD-L1 inhibitor.@*CONCLUSIONS@#The second-line treatment with docetaxel plus PD-1/PD-L1 inhibitor in patients with stage IV NSCLC can improve the DCR and prolong the PFS, and the adverse reactions are tolerable.
ABSTRACT
Objective:To study the relationship between gastric fundus size and postoperative gastroparesis and to find effective ways to prevent postoperative gastroparesis in high-risk patients.Methods:We retrospectively reviewed the clinical data of 276 gastric cancer patients undergoing radical gastrectomy from 2015 to 2016. The gastric fundus volume/total gastric volume (FV/TV) ratio was measured by computed tomography (CT) and comparative study between the gastroparesis group and the non-gastroparesis group was carried out in terms of postoperative gastroparesis. Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive performance. Single-factor and multiple-factor analyses were performed to filter clinically significant predictive factors of gastroparesis. Then, we increased the sample size to 304 patients whose FV/TV ratio was >19.4%. The different surgical methods and perioperative management of these patients were analysed. The chi-square test and logistic regression analysis were performed to identify effective independent factors for preventing gastroparesis.Results:The FV/TV ratio in the gastroparesis group was significantly higher than that in the non-gastroparesis group ( P<0.05). A cut-off value of 19.4% was selected by ROC curve analysis, at which the FV/TV ratio had a sensitivity of 76.2% and a specificity of 53.7%. In 304 patients in the second retrospective study, the incidence of gastroparesis was 9.2%. Gastroparesis was significantly reduced in patients with residual gastric size <1/3 ( P<0.05) and early postoperative gastrointestinal decompression ( P<0.05). Conclusions:The FV/TV ratio can effectively predict the risk of postoperative gastroparesis preoperatively. Small residual stomach and early postoperative gastrointestinal decompression are effective measures to prevent gastroparesis in high-risk patients.
ABSTRACT
OBJECTIVE@#To detect pathogenic variants in a pedigree affected with propionic acidemia (PA).@*METHODS@#The proband was subjected to high-throughput next-generation sequencing. Suspected variants were validated by Sanger sequencing of his family members. mRNA was extracted from peripheral blood lymphocytes from the proband's father in order to verify the impact of the splicing variant by RT-PCR combined with Sanger sequencing. The pathogenicity of the missense variant was predicted by using PolyPhen-2, Mutation Taster, SIFT, COBALT and HOPE software.@*RESULTS@#The proband was found to harbor compound heterozygous variants of the PCCB gene, namely c.184-2A>G and c.733G>A (p.G245S), which were respectively inherited from his father and mother. RT-PCR combined with Sanger sequencing confirmed skipping of exon 2 during transcription. Bioinformatic analysis indicated the c.733G>A (p.G245S) variant to be damaging.@*CONCLUSION@#The two variants of the PCCB gene probably underlay the disease in this patient. Above findings have enriched the spectrum of PCCB gene variants.
