Objective To investigate the effects of different fractions of inspired oxygen administered during general anesthesia on post-operative recovery in patients undergoing laparoscopic hernia repair and hysterectomy in a sub-plateau region.Methods Clinical data of 111 patients undergoing laparoscopic hernia repair and hysterectomy under general anesthesia were collected from the People's Hospital of Datong Hui and Tu Autonomous County between April 2022 and November 2023.Based on the concentration of inhaled oxygen during general anesthesia,patients were randomly divided into three groups:100%oxygen(n=36),80%oxygen(n=38),and 60%oxygen(n=37).Respiratory-related parameters,including arterial partial pressure of oxygen(PaO2),arterial partial pressure of carbon dioxide(PaCO2),and oxygenation index(OI),were compared among the three groups before anesthesia induction,30 min after pneumoperito-neum,and 1 d after surgery.Postoperative pulmonary complications,incision infections,first gastrointestinal exhaust time,and length of hospitalization were recorded.Postoperative delirium and cognitive function were also assessed.Results At 30 min after pneumoperi-toneum induction,the OI in the 60%oxygen group was higher than that in the 100%oxygen group(P=0.009),whereas there was no sta-tistical difference in OI between the 80%oxygen and 100%oxygen groups(P>0.05).PaO2 and OI were lower(P<0.05)and PaCO2 was higher(P<0.05)in all groups on the 1st day after surgery than before the induction of anesthesia.PaO2 and OI were higher in the 80%oxygen group than in the 100%oxygen group(all P<0.05).PaO2 and OI were higher in the 60%oxygen group than in the 100%oxygen and 80%oxygen groups(all P<0.05).PaCO2 was lower in the 60%oxygen group than in the 100%oxygen group(P<0.001).The first gastrointestinal exhaust time was shorter in the 60%oxygen group than in the 100%oxygen group(P=0.019).No postoperative incision infections were observed in any of the three groups,and there were no statistically significant differences in the incidence of postoperative pulmonary complications,length of hospitalization,incidence of postoperative delirium,and cognitive dysfunction among the three groups(all P>0.05).Conclusion During general anesthesia for patients undergoing laparoscopic hernia repair and hysterectomy in a sub-pla-teau region,appropriately reducing the concentration of inspired oxygen(60%)is beneficial for postoperative respiratory and gastrointes-tinal function recovery without increasing the incidence of incision infections,postoperative delirium,and cognitive dysfunction.

Objective:To compare the clinical efficacy of anatomical reconstruction of coracoclavicular ligament at the original insertion point and clavicular hook plate fixation in the treatment of acromioclavicular joint dislocation.Methods:Retrospective analysis was made on the data of 67 patients with acromioclavicular joint dislocation who received surgical treatment in the Department of Orthopaedics of the First Affiliated Hospital of Nanjing Medical University from June 2015 to January 2021. According to the surgical method, they were divided into reconstruction group (using the technique of anatomical reconstruction of coracoclavicular ligament at the original insertion point) and hook plate group (using the clavicular hook plate). There were 37 cases in the reconstruction group, including 26 males and 11 females, aged 47.2±9.6 years (range, 18-65 years), 13 cases on the left and 24 cases on the right. Among the 37 patients, 8 were sports injuries, 14 were falls, 11 were traffic accidents, and 4 were external force injuries. The average time from injury to surgery was 8.3±2.3 days. There were 30 cases in the hook plate group, including 24 males and 6 females, aged 47.4±9.7 years (range, 18-67 years), 12 cases on the left and 18 cases on the right. Among the 30 patients, 7 were sports injuries, 11 were falls, 9 were traffic accidents, and 3 were external force injuries. The average time from injury to surgery was 7.9±2.6 days. The surgical time, incision length, intraoperative bleeding, hospital stay, postoperative coracoclavicular separation ratio, and postoperative complications were compared between the two groups. Constant-Murley score and visual analog scale (VAS) were used to assess the shoulder joint function and pain degree of patients.Results:Both groups of patients were followed up, with a follow-up time of 12.3±0.4 months for the reconstruction group and 12.2±0.5 months for the hook plate group. The operation time (105.8±10.0 min), incision length [12.0 (11.0, 13.0) cm] and hospitalization time (6.8±2.1 d) in the reconstruction group were longer than those in the hook plate group [48.3±4.9 min, 10.0 (10.0, 11.0) cm, and 5.5±2.7 d], while the intraoperative blood loss (75.1±3.9 ml) was less than that in the hook plate group (90.3±6.3 ml), the differences were statistically significant ( P<0.05). The VAS [4.0 (3.0, 5.0), 3.0 (3.0, 3.0), 2.0 (1.0, 2.0) points] and Constant-Murley score (65.4±4.5, 84.9±2.5, 90.1±2.5 points) of the reconstruction group at 3 days, 3 months, and 12 months after surgery were better than those of the hook plate group [5.0 (4.0, 5.0), 4.0 (4.0, 4.0), 3.0 (3.0, 4.0) and 56.9±3.5, 79.6±4.0, 86.8±2.4 points], the difference was statistically significant ( P<0.05). At the last follow-up, there was a statistically significant difference in the separation ratio of coracoclavicular distance between the reconstruction group (0.12±0.08) and the hook plate group 0.22±0.15 ( t=3.25, P=0.002). There was no significant difference ( Z=-0.52, P=0.605) in the separation ratio of acromioclavicular distance [0.16 (0.05, 0.25) and 0.16 (0.04, 0.40)]. In the hook plate group, 6 cases had shoulder joint foreign body sensation and 2 cases had acromioclavicular joint redislocation (both Rockwood type III). Because the shoulder joint function did not affect their daily life, neither patient underwent secondary surgery. And no case of acromioclavicular joint redislocation occurred in the reconstruction group. Conclusion:Compared with the clavicular hook plate fixation, anatomic reconstruction of coracoclavicular ligament at the original insertion point in the treatment of acromioclavicular joint dislocation can reduce the pain of the shoulder joint earlier, which has the characteristics of small trauma, good effect, and reduces the steps of internal fixation removal, and has good clinical curative effect.

Abstract Cognitive behavior therapy (CBT) is one of the main psychotherapeutic methods used to treat anxiety disorders in children and adolescents. Art therapy, based on psychotherapy theory and methods, is rising in popularity abroad. At present, foreign scholars have started to apply cognitive behavioral art therapy (CBAT) for patients with anxiety disorders. Based on the current findings, children and adolescents with developing cognitive functions may also benefit from this therapy. This article summarizes the application status of CBAT in the treatment of anxiety disorder in patients at home and abroad, and innovatively explores its therapeutic potential for anxiety disorders in children and adolescents in China, thus providing a novel perspective that can address the shortcomings of CBT.

Both cholinergic dysfunction and protein citrullination are the hallmarks of rheumatoid arthritis (RA), but the relationship between the two phenomena remains unclear. We explored whether and how cholinergic dysfunction accelerates protein citrullination and consequently drives the development of RA. Cholinergic function and protein citrullination levels in patients with RA and collagen-induced arthritis (CIA) mice were collected. In both neuron-macrophage coculture system and CIA mice, the effect of cholinergic dysfunction on protein citrullination and expression of peptidylarginine deiminases (PADs) was assessed by immunofluorescence. The key transcription factors for PAD4 expression were predicted and validated. Cholinergic dysfunction in the patients with RA and CIA mice negatively correlated with the degree of protein citrullination in synovial tissues. The cholinergic or alpha7 nicotinic acetylcholine receptor (α7nAChR) deactivation and activation resulted in the promotion and reduction of protein citrullination in vitro and in vivo, respectively. Especially, the activation deficiency of α7nAChR induced the earlier onset and aggravation of CIA. Furthermore, deactivation of α7nAChR increased the expression of PAD4 and specificity protein-3 (SP3) in vitro and in vivo. Our results suggest that cholinergic dysfunction-induced deficient α7nAChR activation, which induces the expression of SP3 and its downstream molecule PAD4, accelerating protein citrullination and the development of RA.

Objective:To analyze the clinicopathological characteristics, treatment responses and kidney outcomes of patients with atypical membranous nephropathy (MN), and to provide information for the clinical practice.Methods:The clinical data of patients with atypical MN and synchronous primary MN who were diagnosed, treated and followed up in Peking University First Hospital from January 2008 to June 2020 were retrospectively collected and analyzed. Clinicopathological features, treatment responses and kidney prognosis were compared between the two groups. The expression of phospholipase A2 receptor (PLA2R) in kidney tissues was detected by immunofluorescence. Serum anti-PLA2R antibody was detected by enzyme-linked immunosorbent assay. Clinicopathological indexes were compared between PLA2R-related MN group and non-PLA2R-related MN group. Kaplan-Meier (Log-rank test) survival curve and multivariate Cox regression analysis methods were used to analyze the influencing factors of kidney prognosis in patients with atypical MN. The primary endpoint of renal adverse outcome was renal insufficiency, defined as end-stage renal disease or estimated glomerular filtration rate (eGFR) decline>30% baseline and<60 ml·min -1·(1.73 m 2) -1. Results:A total of 65 atypical MN patients were enrolled in this study. Compared with primary MN ( n=324), patients with atypical MN had younger age ( Z=-4.229, P<0.001), higher proportion of hematuria ( χ2=5.555, P=0.018), higher level of urinary protein ( Z=2.228, P=0.026) and lower level of eGFR ( t=-5.108, P<0.001); the proportion of IgG4 deposition in kidneys was lower ( χ2=8.081, P=0.004), and the proportions of IgA ( χ2=16.969, P<0.001) and IgM ( χ2=9.281, P=0.002) deposition were higher. There was no significant difference on gender, serum albumin, positive proportion of anti-PLA2R antibody, anti-PLA2R antibody level and kidney C3/C1q deposition between the two groups (all P>0.05). The proportions of atypical MN patients receiving renin-angiotensin aldosterone system inhibitors (49.3% vs 57.1%), calcineurin inhibitors (27.7% vs 19.1%) and cyclophosphamide (21.5% vs 23.8%) were comparable to those of primary MN patients (all P>0.05). The rates of clinical remission (80.0% vs 77.2%), partial remission (44.6% vs 44.1%), complete remission (35.4% vs 33.1%), spontaneous remission (36.9% vs 42.6%), response to cyclophosphamide (85.7% vs 81.8%), response to calcineurin inhibitor (88.9% vs 79.0%), and relapse (30.8% vs 26.8%) in atypical MN patients were comparable to those in primary MN patients (all P>0.05). During the follow-up 30.0(21.5, 61.5) months, 15 atypical MN patients (23.1%) had eGFR reduction>30%, among whom 7 patients (10.8%) had eGFR reduction>50% and 3 patients (4.6%) had end-stage kidney disease. There was no significant difference on poor kidney prognosis between the two groups (all P>0.05). Kaplan-Meier survival curve showed that patients with age>39 years old ( χ2=10.092, P=0.001), eGFR≤100 ml·min -1·(1.73 m 2) -1( χ2=5.491, P=0.019), tubular interstitial lesion ( χ2=6.999, P=0.008) and no nephropathy remission ( χ2=22.952, P<0.001) had earlier poor renal prognosis. Multivariate Cox regression analysis showed that no nephropathy remission ( HR=12.604, 95% CI 2.691-59.037, P=0.001) was an independent influencing factor for poor renal prognosis in atypical MN patients. Conclusion:No significant difference is found between atypical MN and primary MN on treatment responses and kidney prognosis, which implies that clinical practice of atypical MN can be performed by referring to the guidelines and experience of primary MN.

To investigate the temporal trend of antibiotic use among children in Shanghai from 2017 to 2020. The stratified cluster sampling method was used to establish a dynamic cohort of healthy children based on primary schools in Changning District, Shanghai. In the cohort, there were 282 children from 2017, 287 children from 2018, 294 from 2019 and 301 from 2020. A total of 700 children aged 7-11 years were included in the study. The basic information and antibiotic use of children were investigated by questionnaire every year, and their height and weight were measured at the same time. Chi-square test was used to analyze the difference of antibiotic use rate in each year and generalized estimation equation was used to analyze the temporal trend of antibiotic use. The results showed that the use rates of all antibiotics, cephalosporins, azithromycin and other antibiotics (including penicillin, lincomycin, quinolones, etc.) of children between 2017 and 2020 were 15.6%, 10.5%, 2.7%, and 2.4%, respectively. In 2017, 2018, 2019, and 2020, there were significant differences for the use rates of total antibiotics and other antibiotics in children ( P=0.033, P=0.040), and there were no significant differences for the use rates of cephalosporins and azithromycin ( P=0.274, P=0.455). After adjusting for children′s basic characteristics, the generalized estimation equation showed that the annual use rate of all antibiotics, cephalosporins, and other antibiotics decreased over time.

Purpose: This study compared the diagnostic performance of the Ovarian-Adnexal Reporting and Data System (O-RADS), the Risk of Malignancy Index 4 (RMI4), the International Ovarian of Tumor Analysis Logistic Regression Model 2 (IOTA LR2), and the IOTA Simple Rules (IOTA SR) in predicting the malignancy of adnexal masses (AMs). Methods: This retrospective study included 575 women with AMs between 2017 and 2020. All clinical messages, ultrasound images, and pathological findings were collected. Two senior doctors (group I) and two junior doctors (group II) used the four systems to classify AMs. The postoperative pathological diagnosis was used as the gold standard to evaluate the diagnostic efficiency. A receiver operating characteristic curve was used to test the diagnostic performance. The interrater agreement between the two groups was tested using kappa values. Results: Of all 592 AMs, 447 (75.5%) were benign, 123 (20.8%) were malignant, and 22 (3.7%) were borderline. The intergroup consistency test yielded kappa values of 0.71, 0.92, 0.68, and 0.77 for the O-RADS, RMI4, IOTA LR2, and IOTA SR, respectively. To predict malignant lesions, the areas under the curve of the O-RADS, RMI4, IOTA LR2, and IOTA SR systems were 0.90, 0.89, 0.90, and 0.86 for group I and 0.89, 0.87, 0.88, and 0.84 for group II, respectively. The O-RADS had the highest sensitivity (91.0% in group I and 84.8% in group II). Conclusion The four diagnostic systems could compensate for junior doctors’ inexperience in predicting malignant adnexal lesions. The O-RADS performed best and showed the highest sensitivity.

Objective:To explore the effect of the discharge preparation plan based on community linkage in the out-of-hospital continuous nursing of chronic obstructive pulmonary disease (COPD) patients.Methods:From March 2019 to March 2020, convenience sampling was used to select 206 COPD patients hospitalized in the Respiratory Department of Henan Provincial People's Hospital. The patients were randomly divided into the observation group and the control group, with 103 cases in each group. The control group received routine management of COPD, and the observation group implemented a community-linked discharge preparation plan on the basis of the control group, and carried out a six-month intervention. The COPD Assessment Test (CAT) score, Patient Assessment of Chronic Illness Care (PACIC) score, body mass index, degree of airflow obstruction, dyspnea and exercise capacity (BODE) index, and the patient readmission rate during the intervention period were compared between the two groups before and after the intervention.Results:After the intervention, the item scores and total scores of the CAT of the observation group were lower than those of the control group. Except for cough and sputum, the differences in the other items and total scores were statistically significant ( P<0.05) . The item scores and total scores of the CAT of the observation group after intervention were lower than those before intervention, and the differences were statistically significant ( P<0.05) . The dimension scores and total score of the PACIC of the observation group after the intervention were higher than those before the intervention, and were higher than those of the control group after the intervention, and the difference was statistically significant ( P<0.05) . The BODE index score of the observation group after intervention was lower than that of the control group, and the difference between the two groups was statistically significant ( P<0.05) . The readmission rate in the observation group within six months was 13.59% (14/103) , which was lower than 31.07% (32/103) in the control group, and the difference between the two groups was statistically significant (χ 2=9.068, P=0.003) . Conclusions:The discharge preparation plan based on community linkage can improve the quality of life and lung function of COPD patients, increase the patient's recognition of chronic disease management, reduce the rate of hospital readmission, and achieve the overall quality improvement in continuous nursing of patients.
