ABSTRACT
Objective:To evaluate the diagnostic efficacy of prostate imaging recurrence reporting (PI-RR) system for detecting local recurrence after radical prostatectomy (RP) in prostate cancer (PCa) and to assess the consistency of the PI-RR scores assigned by different seniority radiologists.Methods:This study was a cross-sectional study. A total of 176 PCa patients who underwent multi-parametric MRI (mpMRI) for biochemical recurrence (BCR) after RP from July 2015 to October 2021 at the First Affiliated Hospital of Soochow University were retrospectively collected. The mpMRI images were reviewed and the PI-RR scores of the main lesions were assigned independently by six different seniority radiologists (2 junior, 2 senior and 2 expert radiologists). Following the reference standard determined by biopsy pathologic results, follow-up imaging, or prostate specific antigen levels, the patients were divided into two groups: 54 patients with local recurrence and 122 patients without local recurrence. The intraclass correlation coefficient ( ICC) and Kappa test were used to evaluate the consistency of the PI-RR scores by different seniority radiologists. The receiver operating characteristic (ROC) curve analysis was employed to evaluate the diagnostic efficacy of the PI-RR scores assessed by different seniority radiologists for detecting local recurrence of PCa after RP. The DeLong test was utilized to compare the areas under the ROC curve (AUC) of different seniority radiologist PI-RR scores and a false discovery rate (FDR) was applied to correct results using the Benjamini and Hochberg method. Sensitivity and specificity were calculated according to the cutoff value of PI-RR score≥3 or 4. Results:The ICC (95% CI) of all different seniority radiologists was 0.70 (0.64-0.76). The Kappa value was 0.528, 0.325 and 0.370 respectively between expert and senior radiologists, expert and junior radiologists, senior and junior radiologists. The AUC (95% CI) of junior, senior, and expert radiologists were separately 0.73 (0.65-0.81), 0.81 (0.74-0.88), and 0.86 (0.80-0.93). The AUC of the expert radiologist PI-RR score was higher than those of senior and junior radiologist PI-RR scores ( Z=2.22, 3.21, FDR P=0.039, 0.003). The PI-RR score of senior radiologist had higher AUC than that of junior radiologist ( Z=2.22, FDR P=0.026). With the PI-RR score of 3 or greater as a cutoff value, the sensitivity of junior, senior and expert radiologists were respectively 0.59, 0.65, and 0.78 and the specificity were 0.82, 0.93, and 0.95. With the PI-RR score of 4 or greater as a cutoff value, the sensitivity of junior, senior and expert radiologists were respectively 0.50, 0.54, and 0.69 and the specificity were 0.88, 0.96 and 0.97. Conclusion:PI-RR score can accurately diagnose local recurrence of PCa after RP. PI-RR score has a moderate inter-reader consistency across different seniority radiologists. And the diagnostic performance is influenced by the experience of radiologists.
ABSTRACT
Background@#Irritable bowel syndrome (IBS) is a functional bowel disorder (FBD). @*Objectives@#To assess the therapeutic effects of paeoniflorin (PF) on IBS in rats.Method: Sixty male Sprague–Dawley rats were randomly divided into normal, model, positive drug, low-dose PF, medium-dose PF and high-dose PF groups (n = 10). After gavage for 2 consecutive weeks, the effect of PF on abdominal pain symptoms was assessed based on the abdominal withdrawal reflex (AWR) score, fecal water content and pathological changes in colon tissues. D-lactate, interleukin-1β (IL-1β), transforming growth factor-β (TGF-β) and tumor necrosis factor-α (TNF-α) were detected by enzyme-linked immunosorbent assay, and phosphorylated nuclear factor kappa B (p-NF-κB) p65 was detected by Western blotting. The abundance and diversity changes of intestinal flora were explored using 16S ribosomal RNA sequencing.Result: In PF groups, the mucosal morphology of colon tissues was intact, and the glands were arranged neatly and structured clearly, without obvious inflammatory cell infiltration.Compared with the model group, PF groups had significantly elevated pain threshold, and mRNA and protein levels of zonula occludens-1 (ZO-1) and occludin, decreased AWR score at 20 mmHg pressure, fecal water content, mRNA levels of IL-1β, TGF-β, and TNF-α, protein level of p-NF-κB p65 and level of serum D-lactate, and reduced levels of serum IL-1β, TGF-β, and TNF-α (p < 0.05, p < 0.01). PF groups had higher abundance of Lactobacillus, Akkermansia, Alistipes, and Bacteroides, but lower abundance of Desulfovibrio, Parasutterella, and Enterococcus than those of the model group. @*Conclusions@#PF exerts therapeutic effects on IBS in rats probably by regulating the intestinal flora, and then up-regulating the expressions of ZO-1 and occludin in colon tissue while down-regulating the levels of IL-1β, TGF-β, TNF-α, D-lactate and p-NF-κB p65.
ABSTRACT
Objective:To develop and test the reliability and validity of the assessment scale for patients with persistent vegetative state (PVS) or minimally conscious state (MCS) discharge from the anesthesia recovery room after operation.Methods:From September 2018 to October 2020, three dimensions and 17 item pools were determined through literature review and discussion among the project members. Two rounds of expert consultation were conducted to determine the respiratory (R), circulatory (C), oxygenation (O), bispectral index (B) and neuromuscular monitoring (N) scale (RCOBN scale), the reliability and validity were tested. 87 patients with PVS or MCS after operation Affiliated Sichuan Bayi Rehabilitation Center of Chengdu University of Traditional Chinese Medicine were selected to verify the effectiveness.Results:In the first round, 23 questionnaires were distributed. The total score of experts was 50 ± 3, F=9.24, CV were 0.00-0.43. The Cronbach α coefficient of each dimension was 0.782-0.846, and the Cronbach α coefficient of the total scale was 0.813. In the second round, 10 questionnaires were distributed. The item-level content validity index was 0.7-1.0, the probability of random consistency ( Pc) was 0.001-0.117, the adjusted kappa value ( k*) was 0.567-1.000, and the sum of the index scores corresponding to k* > 0.74 was 8. The scale-level content validity index of the overall consistency was 0.87. The ratio of patients transferred out of PACU by two rounds of evaluation method was 100 : 96.55, and the difference was not statistically significant ( χ2=3.05, P>0.05). The time of the first round of assessment was significantly longer than that of the second round, which were (197 ± 52) s and (58 ± 14) s respectively.

ABSTRACT
Objective:To investigate the effect of prospective intervention on emergence agitation and postoperative recovery in patients with chronic sinusitis during preoperative visits.Methods:A total of 80 patients with chronic sinusitis who underwent general anesthesia in Dayi County People′s Hospital of Chengdu City from December 2019 to October 2020 were selected and randomly divided into group D and group G, with 40 patients in each group. Group D received preoperative visit with conventional methods and group G received preoperative visit with prospective intervention methods. The hemodynamic changes of patients in the two groups at 30 min before the operation (T 1) and 1 (T 2), 5 (T 3), 10 (T 4) and 30 min (T 5) after tracheal tube extraction were recorded. The anxiety and depression scores of patients before the intervention and 1 d after the operation were compared between the two groups. The incidence of emergence agitation after the operation and complications during anesthesia awakening period were observed in the two groups, sino-nasal outcome test-20 (SNOT-20) was used to assess the postoperative recovery. Results:The incidence of emergence agitation in group G was lower than that in group D: 7.5%(3/40) vs. 25.0%(10/40), the difference was statistically significant ( χ2 = 4.50, P<0.05). There was no significant difference in systolic blood pressure, diastolic blood pressure and heart rate between the two groups at T 1 and T 5 ( P>0.05), but the level of above indicators in group G at T 2, T 3 and T 4 were significantly higher than those in group D ( P<0.05). The scores of State-Trait Anxiety Inventory(S-AI) and Self-Rating Depression Scale (SDS) in group G at the first day after the operation were significantly lower than those in group D: (35.45 ± 5.32) scores vs. (39.35 ± 4.91) scores, (35.42 ± 7.82) scores vs. (38.76 ± 5.21) scores, the differences were statistically significant ( P<0.05). The incidence of complications during anesthesia awakening period in group G was slightly lower than that in group D ( P>0.05). After the operation, the scores of sinusitis symptoms and nasal symptoms in the two groups were significantly decreased compared with those before the operation, and the scores of group G were significantly lower than those in group D ( P<0.05). Conclusions:Prospective intervention before anesthesia in patients with chronic sinusitis surgery can reduce stress response, improve bad mood, reduce the incidence of emergence agitation, and promote the postoperative recovery.
ABSTRACT
Objective:To investigate the clinical effects of Ilizarov external fixation combined with bone surface roughening technique in the treatment of tibial dystrophic nonunion.Methods:The data were retrospectively studied of the 11 patients with tibial dystrophic nonunion who had been treated at Department of Orthopedics, 920 Hospital of the Joint Logistic Support Force of PLA from April 2018 to January 2021. They were 7 males and 4 females, aged from 32 to 61 years (average, 44.6 years). Their last surgical fixation before admission was Hoffman Ⅱ external fixation in 6 cases and locking plate internal fixation in 5 cases. The time from their last operation to the present operation ranged from 9 to 26 months (average, 14.2 months). After treatment by Ilizarov external fixation combined with bone surface roughening technique, the 11 patients started weight-bearing walking with double crutches from the second day after operation, gradually progressed to walking with a single crutch 2 months after operation, and resumed normal weight-bearing walking without any crutch 3 months after operation.Results:All the 11 patients were followed up for 12 to 30 months (average, 20.0 months). The time for bearing Ilizarov external fixation ranged from 6 to 10 months (average, 8.6 months). Mild pin track infection occurred in 4 cases but was healed by pin track rinse with normal saline; moderate pin track infection happened in another 2 cases but responded to oral amoxicillin capsules for one week in addition to pin track rinse with normal saline. All the bone dystrophic nonunion was cured after 6 to 10 months (average, 8.6 months). By the bone criteria of Association for Study and Application of Method of Ilizarov (ASAMI), the efficacy was excellent in 8 cases, good in 2 and fair in one at the last follow-up; by the limb function criteria of ASAMI, the efficacy was excellent in 9 cases and good in 2 at the last follow-up.Conclusion:Ilizarov external fixation combined with bone surface roughening technique is an effective treatment of tibial dystrophic nonunion.
ABSTRACT
Objective:To evaluate the efficay of different doses of remimazolam for anesthesia induction during reoperation in asthenic patients with tracheotomy.Methods:One hundred and twenty patients of both sexes, aged 19-64 yr, with a modified frailty index score ≥3, of American Society of Anesthesiologists physical status Ⅳ, scheduled for reoperation after tracheotomy, were divided into 4 groups ( n=30 each)using a random number table method: propofol group (group C) and different doses of remimazolam groups (R 1, R 2 and R 3 groups).

The onset time of anesthesia and adverse reactions such as hypotension, bradycardia and bucking during replacement of the tube, and requirement for rescue sedation were recorded. Results:Compared with group C, mean arterial pressure was significantly increased at T 1, 2 in group R 1 and group R 2, the onset time of anesthesia was significantly prolonged, the incidence of hypotension and bradycardia was decreased in R 1, R 2 and R 3 groups, and the requirement for rescue sedation in group R 1 and incidence of bucking in group R 1 and group R 2 were increased ( P<0.05 or 0.01). Compared with group R 1, heart rate at T 2 was significantly decreased, the onset time of anesthesia was shortened, and the requirement for rescue sedation and incidence of bucking were decreased in C, R 2 and R 3 groups, and the incidence of hypotension was significantly increased in group R 3 ( P<0.05 or 0.01). Compared with group R 2, the onset time of anesthesia was significantly shortened in group R 3 ( P<0.05). Conclusions:Remimazolam 0.2 mg/kg provides good efficacy when used for anesthesia induction with fewer side effects during reoperation in asthenic patients with tracheotomy.
ABSTRACT
Objective:To evaluate the efficacy of remimazolam combined with low-dose propofol for sedation during induction of anesthesia.Methods:A total of 228 patients of both sexes, aged 18-64 yr, with body mass index of 19-35 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic cholecystectomy, were divided into 2 groups ( n=114 each) by a random number table method: remimazolam combined with low-dose propofol group (group R) and propofol group (group P). Anesthesia was induced with intravenous injection of sufentanil 0.3 μg/kg, remimazolam 0.3 mg/kg, propofol 0.5 mg/kg and micuronium 0.2 mg/kg in group R, and sufentanil 0.3 μg/kg, propofol 2 mg/kg and micuronium 0.2 mg/kg in group P. Endotracheal intubation was performed when bispectral index value ≤ 50.Before induction (T 0), immediately before intubation (T 1), at 1 min (T 2) and 3 min (T 3) after intubation, mean arterial pressure (MAP) and heart rate (HR) were recorded.The anesthesia induction time and the incidence of hypotension and bradycardia were recorded in the two groups. Results:There was no significant difference in MAP and HR at T 0 between the two groups ( P>0.05). Compared with the value at T 0, MAP in two groups and HR were significantly decreased at T 1-3 in group P ( P<0.01). Compared with group P, the anesthesia induction time was significantly prolonged, and hypotension and bradycardia was decreased in group R ( P<0.05). Conclusion:The combination of remimazolam and low-dose propofol exerts better efficacy for sedation during induction of anesthesia than propofol alone.
ABSTRACT
Objective To explore the clinical application of our self-designed controllable and portable double-pin traction device on calf in the treatment of tibiofibular fractures.Methods Our controllable and portable double-pin traction device on calf was designed to fulfill the purpose of traction and address current problems in traction for tibiofibular fractures.This device is composed of double-hole connectors,nuts of various specifications,traction pin sleeves,2 transfixion pins and 2 threaded rods for traction.The transfixion pins are fixed at conventional traction positions.The threaded rods for traction are paralleled to the long axis of lower limb and located on both sides of the calf.Bone ends can be distracted by adjusting the nut of M8 width and the speed of pulling can be controlled.This device can be used not only for rapid traction during surgery but also for slow traction preoperatively.It was applied in the 30 patients with tibiofibular fracture who had been treated at Department of Orthopaedic Surgery,920th Hospital of Joint Logistic Support Force from January to December 2017.Their radiographs were taken before traction and at 3 and 6 days after traction to observe the changes in overlapped fracture ends and fracture gap.The lengths of distraction were measured.After limited open reduction,fracture gaps and tensions of surrounding soft-tissues were observed.Results Their radiographs before and after traction demonstrated that their overlapped and displaced fracture ends were distracted more or less.The length of distraction ranged from 7.2 mm to 45.8 mm (mean,23.1 mm);it was < 15 mm in 6 cases,between 15 mm and 30 mm in 18,between 31 mm and 45 mm in 5,and > 45 mm in one.Their radiographs showed that regular traction for 6 days was more obvious than that for 3 days.The limited open reduction revealed that the gap between fracture ends was expanded,the soft-tissue tension effectively relaxed,the overlapping of fracture ends diminished,and the dissection of surrounding soft-tissue and periosteum decreased,leading to less difficulty in reduction.In fractures near the joint or involving the articular surface,the joint space was expanded.The 30 patients were followed up for one to 16 months (mean,5.8 months).No such complications as pin site infection,traction fracture or osteomyelitis was observed.Conclusion Our self-designed controllable and portable double-pin traction device on calf is effective and advantageous,because it is simple,easy,light in weight,and controllable for traction speed.
