ABSTRACT
Objective To investigate the effects of nalbuphine combined with dexmedetomidine on postop-erative recovery quality and pain in patients who undergoing laparoscopic bariatric surgery.Methods A total of 169 patients who underwent laparoscopic bariatric surgery at our hospital were included and divided into control group(group C),nalbuphine group(group N),dexmedetomidine group(group D),and nalbuphine combined with dexme-detomidine group(group ND)using randomised numerical table method.Group C received intravenous injection of saline,group N and group ND received intravenous injection of nalbuphine before the end of the surgery,and group D and group ND received pumping of dexmedetomidine before anesthesia induction and during surgery.Compare the postoperative recovery quality score(QoR-40),hemodynamics at different time points,visual analogue scale score(VAS),sedation-agitation scale(SAS),first time out of bed activity and exhaust time,and incidence of nausea and vomiting among four groups.Results The postoperative QoR-40 scores of patients in group ND were better than those in group C and group N(P<0.05),and the QoR-40 scores in group D were better than those in group C(P<0.05).MAP and HR were more stable during the awakening period in group ND and group D(P<0.05).Compared with group C,patients in all three groups had lower VAS scores and SAS scores(P<0.05)and consumed less remedial analgesic medication(P<0.05).In terms of adverse reactions,the incidence of postoperative nausea,vomiting and coughing in the group ND was lower than that in the group C(P<0.05).Conclusion The combination of nalbuphine and dexmedetomidine could improve the quality of postoperative recovery and pain in patients under-going laparoscopic bariatric surgery,reduce hemodynamic fluctuations during the patients′ recovery period,reduce the incidence of nausea and vomiting,and improve the patients′ prognosis.
ABSTRACT
Objective:To study the position of computed tomography(CT)slice of marker points of radiotherapy,which was determined by control scan(CS)method,on the application effect of patients with head and neck tumors who received radiotherapy.Methods:Based on Control Scan(CS)method,a calculator program of mark-point slice position was made,which was an enterprise WeChat program that could be used in calculating position and CT position scan of patients with head and neck tumor(slice thickness was 3mm).A total of 60 patients with head and neck tumor were selected,and the patients who underwent CT positioning scan by using CS method were divided into observation group,and patients who underwent CT position scan by using conventional method were divided into control group,with 30 cases in each group.The number of cases with three metal marker points displayed at the same slice,and the number of slices containing the CT images of marker point between the located CT scan were compared.Results:The number of patients in the observation group and the control group who showed three markers at the same level at the same time were respectively 26 cases and 13 cases,and observation group increased by 13 cases(43.4%)than control group,and the difference was significant(x2=12.382,P<0.05).The number of CT images with only 1 slice of observation group and control group were respectively 4 cases and 0 cases,which increased by 4 cases(13.3%)than the control group,and the difference was significant(x2=2.411,P<0.05).Conclusions:The CT localization scan of radiotherapy,which uses CS to assist patients with head and neck tumor,can precisely calculate and obtain the primary position of target of CT localization scan.It can take the images of 3 mental marker points of patient who receives radiotherapy to occur at the same CT slice as soon as possible,which has better application effect.It can effectively improve the convenience and work effectiveness of radiotherapy.
ABSTRACT
Objective:To investigate the application effect of discharge preparation service based on theory of goal attainment on patients with cervical spinal cord injury.Methods:A retrospective cohort study was conducted to analyze the clinic data of 60 patients with cervical spinal cord injury admitted to Zhengzhou Orthopedics Hospital from January 2017 to December 2022, including 49 males and 11 females, aged 23-79 years [(52.2±13.5)years]. Patients were all treated with cervical decompression fusion and internal fixation. Patients admitted from January 2017 to December 2019 were treated with conventional nursing intervention (conventional nursing group, n=30) and patients admitted from January 2020 to December 2022 were treated with discharge preparation service based on theory of goal attainment (discharge preparation service group, n=30). The readiness for hospital discharge of the two groups was compared using the Chinese version of Readiness for Hospital Discharge Scale (RHDS) at 4 hours before discharge. The degree of cervical spinal cord dysfunction of the two groups were compared using Japanese Orthopedic Association (JOA) score before intervention, at discharge and at 6 months after discharge. The complication and unplanned readmission rates of the two groups were compared at 6 months after discharge. Results:All the patients were followed up for 6 months. At 4 hours before discharge, the scores of the three parameters of RHDS containing personal status, adaptability and anticipatory support and the total score of the discharge preparation service group were (20.9±3.5)points, (35.9±2.2)points, (30.4±3.0)points and (87.1±7.8)points respectively, higher than those of the conventional nursing group [(16.2±1.7)points, (32.5±2.2)points, (26.3±2.1)points and (75.0±5.6)points respectively] ( P<0.01). There was no statistically significant difference in the JOA score of the two groups before intervention ( P>0.05). The JOA scores of the discharge preparation service group at discharge and at 6 months after discharge were (11.8±1.7)points and (13.8±1.5)points respectively, higher than those of the conventional nursing group [(10.3±1.8)points and (11.6±1.9)points respectively] ( P<0.01). At 6 months after discharge, the complication rate of the discharge preparation service group was 6.7% (2/30), lower than that of the conventional nursing group [36.7% (11/30)] ( P<0.05). The unplanned readmission rate of the discharge preparation service group was 3.3% (1/30), lower than that of the conventional nursing group [23.3% (7/30)] ( P<0.05). Conclusion:For patients with cervical spinal cord injury, discharge preparation service based on theory of goal attainment can improve the discharge readiness, promote spinal functional recovery and reduce the complication and unplanned readmission rates.
ABSTRACT
Objective:To investigate the effects of SINC, a novel secreted protein of Chlamydia psittaci, on the apoptosis of host cells and the regulatory role of mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) signaling pathway in it. Methods:HeLa cells were treated with recombinant SINC. The expression of Bax and Bcl-2 at protein level and the phosphorylation of ERK1/2 were analyzed by Western blot. Hoechst 33258 staining was used to detect the apoptosis of HeLa cells after SINC stimulation. Moreover, HeLa cells were pretreated with MEK1/2 inhibitor U0126 (50 μmol/L), and then stimulated with different concentrations of SINC for different time. Flow cytometry was used to detect the changes in cell apoptosis rates and Western blot was performed to detect the expression of Bax and Bcl-2 at protein level.Results:Treating HeLa cells with 10 μg/ml of SINC for 18 h resulted in down-regulated Bax and up-regulated Bcl-2 at protein level. Besides, the ratio of Bax/Bcl-2 was the lowest and a significant increase in the ratio of phosphorylated ERK1/2 (p-ERK1/2) to ERK1/2 was observed. Hoechst 33258 staining showed that the number of apoptotic bodies decreased significantly after stimulating HeLa cells with 5, 10 and 15 μg/ml of SINC. In the presence of MEK1/2 inhibitor U0126, the expression of Bcl-2 at protein level was down-regulated, while the expression of cleaved PARP was significantly up-regulated. Flow cytometry showed a significantly enhanced apoptosis of HeLa cells.Conclusions:SINC can inhibit the apoptosis of HeLa cells through activating the MAPK/ERK signaling pathway.

Generalization, the ability to apply learned knowledge or skills to different materials, individuals, or situations, is a challenge for children with autism. This difficulty in generalization hampers their development of independent living, learning, and working skills. Multiple exemplar training is a widely-used and effective teaching method in the field of autism education. This article provides an explanation of the different types of exemplars used in multiple exemplar training, the steps involved in teaching, and various areas of application. Practical recommendations are also offered based on this information, aiming to support skill learning and generalization research for children with autism in our country.
ABSTRACT
Objective To analyze the epidemiological characteristics and spatial-temporal distribution of drug-resistant tuberculosis in Pudong New Area from 2016 to 2021 and to provide scientific basis for the prevention and control of drug-resistant tuberculosis. Methods The data of tuberculosis patients in Pudong New Area from 2016 to 2021 were collected through the Tuberculosis Information Management System of China Disease Prevention and Control Information System. The geographic information database was established by ArcGIS software and the vector map of Pudong New Area for trend surface analysis and spatial autocorrelation analysis . Results From 2016 to 2021, a total of 3916 patients with etiological positive tuberculosis were found to be drug resistant with the drug resistance rate of 13.13%. The drug resistance rate of each year showed a decreasing trend (χ2trend=14.917, P<0.001). The rates of drug resistance of male, retiree, age 50~<60 years old, 60~<70 years old and recurrent patient were higher. From 2016 to 2021, the incidence of drug-resistant TB showed no spatial aggregation.In the south - north direction, the north is higher than the south generally. In the east - west direction, the west is higher than the east generally. Conclusion Drug resistance screening should be strengthened for men, retirees, over 50 years old, and recurrent TB patients,. Prevention and control measures should be strengthened in street towns with dense population and large floating population.

ABSTRACT
ObjectiveTo investigate the difference of ultrasound characteristics between pure mucinous carcinoma （PMC） and fibroadenoma （FA） of the breast. MethodsUltrasound data of 50 continuous patients with breast PMC from January 2012 to January 2021 and 100 continuous patients with breast FA from June 2018 to January 2019 in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were retrospectively reviewed. The ultrasound characteristics of the two groups were evaluated according to the 2013 BI-RADS Ultrasound Atlas， and the differences in age， maximum diameter and ultrasound characteristics between the two groups were compared. ResultsThe median age of PMC patients was 47 years and that of FA patients was 33 years. The age of PMC patients was higher than that of the FA group， and the difference between the two groups of patients was statistically significant （P<0.001）. The median maximum diameter of PMC patients was 2.4 cm， which was greater than that of the FA group （1.8 cm）， and the difference was statistically significant （P=0.001）. Of the PMC， 70% （35/50） were irregular， 82% （41/50） were parallel to the skin， 92% （46/50） had no circumscribed margin， 72% （36/50） were hypoechoic， and 68% （34/50） had enhanced posterior echo. Of the FA， 69% （69/100） were oval or round， 98% （98/100） were parallel to the skin， 54% （54/100） had circumscribed margin， 98% （98/100） were hypoechoic， and 75% （75/100） had no posterior features. The differences in the above ultrasound characteristics between the PMC and FA groups were statistically significant （P<0.001， P=0.001， P<0.001， P<0.001， P<0.001）. There was no significant difference between calcifications and blood flow. ConclusionsCompared with the FA group， patients with PMC are older and the diameter of the lesions are larger. On ultrasound， the morphology and margin of most breast PMC still show the growth characteristics of invasive cancer. Meanwhile， the posterior echo of PMC is enhanced， which is a unique manifestation.
ABSTRACT
Magnesium-doped calcium silicate (CS) bioceramic scaffolds have unique advantages in mandibular defect repair; however, they lack antibacterial properties to cope with the complex oral microbiome. Herein, for the first time, the CS scaffold was functionally modified with a novel copper-containing polydopamine (PDA(Cu2+)) rapid deposition method, to construct internally modified (*P), externally modified (@PDA), and dually modified (*P@PDA) scaffolds. The morphology, degradation behavior, and mechanical properties of the obtained scaffolds were evaluated in vitro. The results showed that the CS*P@PDA had a unique micro-/nano-structural surface and appreciable mechanical resistance. During the prolonged immersion stage, the release of copper ions from the CS*P@PDA scaffolds was rapid in the early stage and exhibited long-term sustained release. The in vitro evaluation revealed that the release behavior of copper ions ascribed an excellent antibacterial effect to the CS*P@PDA, while the scaffolds retained good cytocompatibility with improved osteogenesis and angiogenesis effects. Finally, the PDA(Cu2+)-modified scaffolds showed effective early bone regeneration in a critical-size rabbit mandibular defect model. Overall, it was indicated that considerable antibacterial property along with the enhancement of alveolar bone regeneration can be imparted to the scaffold by the two-step PDA(Cu2+) modification, and the convenience and wide applicability of this technique make it a promising strategy to avoid bacterial infections on implants.

ABSTRACT
Objective:To investigate the clinical value of dynamic detection of lymphocyte subsets and blood cell counts in management of patients with lupus nephritis (LN).Methods:The clinical data of 65 patients with primary LN admitted in Affiliated Hospital of Qingdao University from January 2015 to April 2021 were retrospectively analyzed. According to the stage of disease progression and medications used,LN patients were classified into primary active phase,post-induction therapy phase,and maintenance therapy phase. The changes in lymphocyte subsets were monitored,and the relationship of lymphocyte subsets and blood cell count ratios with lupus activity and infection events was evaluated.Results:The decrease of CD4 +T lymphocyte and NK cell counts were negatively correlated with the activity of systemic lupus erythematosus (SLE)( r=-0.67,-0.33, P<0.01),while CD8 +T lymphocyte,B cell counts,neutrophil/lymphocyte ratio (NLR),platelet/lymphocyte ratio (PLR),and monocyte/lymphocyte ratio (MLR) were positively correlated with the SLE activity( r=0.38,0.26,0.34,0.26,0.29, P<0.05). The area under ROC curve (AUC) of CD4 +T lymphocyte count in predicting the occurrence of infection in LN patients was the highest (0.89); taking 247.50 cell/μl as cutoff value,the sensitivity and specificity were 81.25% and 87.50%,respectively. The combination of CD4 +T lymphocyte with CRP increased the predicting value for the occurrence of infection. Conclusion:Dynamic detection of blood lymphocyte subsets and blood cell counts can reflect SLE activity and the occurrence of infection in LN patients. Among these indicators the CD4 +T lymphocyte has the highest predictive value for the occurrence of infection,and the combination of the CD4 +T lymphocyte count with CRP level can further improve the predicting value.
ABSTRACT
Objective:To investigate the risk factors of non-valvular paroxysmal atrial fibrillation (NVPAF) with cerebral ischemic stroke(CIS) and analyze NVPAF by using left atrial automatic imaging (AFILA). Logistic regression model was established for left atrial(LA) function parameters.Methods:A total of 205 patients with NVPAF were included in the study and divided into the NVPAF group without ischemic stroke (154 patients) and the CIS group (51 patients). The clinical baseline data, blood biochemical results and AFILA ultrasound data of all patients were collected. Univariate analysis was performed to compare the above data between the two groups of patients. The independent risk factors were obtained by multivariate logistic regression analysis. Logistic regression model was compared with CHA2DS2-VASc scoring system in terms of area under ROC curve, sensitivity and specificity.Results:There were significant differences in age, CHA2DS2-VASc score, taking anticoagulant drugs, history of hypertension, diabetes and coronary heart disease, LAEF, S_R, S_CT, WBC, NEUT, HCY, UREA, NDD, NT-proBNP, Fibrinogen(Fib), Cardiac troponin I(cTnI) and NLR between the two groups (all P<0.05). The results of multifactor analysis showed that: age, hypertension, S_ CT, UREA, NLR, Fib and cTnI were independent risk factors associated with CIS in patients with paroxysmal atrial fibrillation[ OR value: 1.608 ( P=0.003), 3.821 ( P=0.019), 1.259 ( P=0.001), 1.326( P=0.001), 1.352 ( P=0.011), 1.502 ( P=0.042), 7.651( P=0.001)]. After adjusting for the age, sex and history of hypertension included in CHA2DS2-VASc score, S_CT significantly led to NVPAF complicated with stroke[ OR value 1.259 (1.095-1.447), P=0.001]. The diagnostic efficacy of Logistic regression model is better than that of CHA2DS2-VASc scoring (AUC of 0.931 vs 0.717, 95% CI: 0.896-0.967 vs 0.634-0.799, sensitivity of 0.883 vs 0.755, specificity of 0.849 vs 0.713, all P<0.001). Conclusions:Age, hypertension, S_CT, UREA, NLR, fibrinogen, cTnI are independently associated risk factors for patients with combined CIS; The diagnostic efficacy of Logistic regression model is better than that of CHA2DS2-VASc scoring model.And the sensitivity and specificity are high.
ABSTRACT
Objective:To analyze the demands of contracted family doctor service among uncontracted young and middle-aged people in Shanghai Baoshan.Methods:An online questionnaire survey on demands of contracted family doctor service was conducted in June 2021 among 702 uncontracted residents aged 18-60 years from Shanghai Baoshan district selected by stratified random sampling method. The demands of contracted family doctor service, including digital health file, routine laboratory tests and imaging investigation;health promotion;service convenience; home service were surveyed, and the factors related the demands were analyzed with regression analysis.Results:The survey showed that the demands of service convenience (3.8(3.0, 5.0)) and home service (4.0(3.0, 5.0)) were higher, while those of digital health file (3.0(2.0, 5.0)) and health promotion (3.0(2.0, 5.0)) were relatively lower. There were significant differences in the demands of all five contracted services among residents with different gender, age, education level, household register and family income (all P<0.05); while for young residents with different types of medical insurance there was significant difference in demands of all contracted services except digital health file (all P<0.05). Logistic regression analysis indicated that female( OR=1.83, P<0.001), high educational level( OR=4.81, P=0.019), household registered in Shanghai( OR=1.80, P=0.004)had higher demand for service convenience; female gender( OR=1.68, P=0.001), high educational level( OR=4.56, P=0.023)had higher demand for home service demands. Conclusion:The demands for contracted family doctor services are different among the uncontracted young and middle-aged people in Baoshan district, while the service convenience is generally most demanded. The study indicates that the contracted family doctor service should be provided accordingly.
ABSTRACT
The clinical data of 50 children with tracheal bronchus, 35 males and 15 females with a mean age of 1.3 months (9 days to 10 years), diagnosed by bronchoscopy in the First Affiliated Hospital of Xiamen University from July 2017 to September 2021 were collected, including gender, age, symptoms, signs, bronchoscopy manifestations, imaging manifestations, associated diseases, and outcomes. There were 26 cases (52%) of severe pneumonia, 14 cases (28%) of recurrent wheezing, 8 cases (16%) of recurrent cough, and 2 cases (4%) of foreign bodies. The clinical symptoms were cough in 45 cases (90%), phlegm in 37 cases (74%), asthma in 28 cases (56%), and fever in 25 cases (50%). The physical signs were wet rale in 33 cases (66%), dry rale in 24 cases (48%), shortness of breath in 23 cases (46%), and triple concave sign in 21 cases (42%). The site of occurrence of tracheal bronchi was the right wall of the lower segment of the trachea. All 50 patients underwent complete pulmonary imaging examinations, but the presence of tracheal bronchus was reported in only 3 cases (6%). There were 24 cases (48%) with other types of tracheal malformations, including 9 cases (18%) of single malacia, 6 cases (12%) of single tracheal stenosis, 1 case (2%) of external tracheal compression, and 8 cases (16%) of multiple tracheal malformations. There were other underlying diseases in 27 cases (54%), congenital heart disease was the most common (17 cases, 34%), followed by premature infants (9 cases, 18%). In addition, there were 3 cases (6%) of chromosomal diseases, esophageal atresia, tracheoesophageal fistula, and polydactyly. All children were discharged after anti-infection and bronchoscopy alveolar lavage. It is suggested that tracheobronchial malformation can cause infection, as well as other tracheal deformities such as tracheal softening and stenosis.
ABSTRACT
We aimed to evaluate the effectiveness and safety of single-course initial regimens in patients with low-risk gestational trophoblastic neoplasia (GTN). In this trial (NCT01823315), 276 patients were analyzed. Patients were allocated to three initiated regimens: single-course methotrexate (MTX), single-course MTX + dactinomycin (ACTD), and multi-course MTX (control arm). The primary endpoint was the complete remission (CR) rate by initial drug(s). The primary CR rate was 64.4% with multi-course MTX in the control arm. For the single-course MTX arm, the CR rate was 35.8% by one course; it increased to 59.3% after subsequent multi-course MTX, with non-inferiority to the control (difference -5.1%,95% confidence interval (CI) -19.4% to 9.2%, P = 0.014). After further treatment with multi-course ACTD, the CR rate (93.3%) was similar to that of the control (95.2%, P = 0.577). For the single-course MTX + ACTD arm, the CR rate was 46.7% by one course, which increased to 89.1% after subsequent multi-course, with non-inferiority (difference 24.7%, 95% CI 12.8%-36.6%, P < 0.001) to the control. It was similar to the CR rate by MTX and further ACTD in the control arm (89.1% vs. 95.2%, P =0.135). Four patients experienced recurrence, with no death, during the 2-year follow-up. We demonstrated that chemotherapy initiation with single-course MTX may be an alternative regimen for patients with low-risk GTN.

Objective:To compare the clinical value of video laryngoscopy and conventional laryngoscopy for tracheal intubation in neonatal resuscitation.Methods:From July 2018, 100 cases of premature or asphyxia infants born in our hospital requiring tracheal intubation were enrolled. The infants were randomly assigned into video laryngoscopy group and conventional laryngoscopy group with 50 cases in each group. The time needed for intubation, the first time success rate and complications associated with intubation were compared between the two groups.Results:The time needed for intubation (21.7±2.7)s vs.(23.7±1.8)s and the first time success rate [98.0% (49/50) vs. 86.0% (43/50)] were significantly better in the video laryngoscopy group than the conventional laryngoscopy group ( P<0.05). The incidence of intubation complications showed no significant difference between the two groups ( P>0.05). Conclusions:Using video laryngoscopy, the time needed for tracheal intubation is shorter and the first time success rate is higher, without more complications. Video laryngoscopy can be safely used in tracheal intubation of neonatal resuscitation.

ABSTRACT
Objective:To investigate the effects of nedaplatin combined with docetaxel on serum tumor markers and T lymphocyte subsets in patients with epithelial ovarian cancer.Methods:Ninety-two patients with epithelial ovarian cancer who received treatment from March 2016 to December 2017 were included in this study. They were randomly assigned to undergo nedaplatin combined with docetaxel (observation group, n = 46) or cisplatin combined with paclitaxel (control group, n = 46). Both groups received two 21-day courses of treatment. Serum tumor marker level, T lymphocyte subset level, clinical efficacy, incidence of adverse reactions, and 2-year survival rate were compared between the two groups. Results:After treatment, serum cancer antigen 125 (CA125), cancer antigen 199 (CA199), and carcinoembryonic antigen (CEA) levels were (45.84 ± 22.46) U/mL, (35.13 ± 15.03) U/mL, (16.21 ± 3.20) U/mL, respectively in the control group and they were (28.33 ± 20.11) U/mL, (14.82 ± 10.11) U/mL, (5.16 ± 1.33) U/mL, respectively in the observation group. After treatment, CA125, CA199, and CEA levels in each group were significantly decreased compared with before treatment. After treatment, CA125, CA199, and CEA levels were significantly lower in the observation group than in the control group ( t = 3.94, 7.61, 21.63, all P < 0.05). After treatment, the numbers of CD3 +, CD4 +, CD8 + cells in the control group were (16.22 ± 3.12)%, (15.20 ± 1.46)%, (29.21 ± 5.17)%, respectively, and they were (31.22 ± 4.11)%, (24.99 ± 1.71)%, (24.25 ± 4.45)% respectively in the observation group. After treatment, the numbers of CD3 + and CD4 + cells in the observation group were significantly higher than those in the control group ( t = 19.72, 29.53, both P < 0.05). After treatment, the number of CD8 + cells in the observation group was significantly lower than that in the control group ( t = 4.93, P < 0.05). Total response rate was significantly higher in the observation group than in the control group [78.26% (36/46) vs. 58.70% (27/46), χ2 = 4.08, P < 0.05]. The incidence of adverse reactions was significantly lower in the observation group than in the control group [23.91% (11/46) vs. 45.65% (21/46), χ2 = 4.79, P < 0.05]. The 2-year survival rate was significantly higher in the observation group than in the control group [43.48% (20/46) vs. 23.91% (11/46), χ2 = 3.94, P < 0.05]. Conclusion:Nedaplatin combined with docetaxel is highly effective on epithelial ovarian cancer. The combined therapy can greatly reduce serum CA125, CA199, and CEA levels but has no great effects on T lymphocyte subsets. It can increase the survival rate but has no serious adverse reactions.
ABSTRACT
Objective:To evaluate the role of hippocampal REV-ERBα in postoperative cognitive dysfunction in rats.Methods:Thirty-two SPF healthy male Sprague-Dawley rats, aged 12-14 weeks, weighing 360-380 g, were divided into 4 groups ( n=8 each) using a random number table method: control group (group C), surgery group (group S), surgery + dimethyl sulfoxide (DMSO) group (group SD), and surgery + SR9009 group (group SS). Exploratory laparotomy was performed under sevoflurane anesthesia in S, SD and SS groups.Normal saline containing 0.1% DMSO was injected into hippocampal CA1 area at 1 h before laparotomy, with 2 μl on each side in group SD, and REV-ERBα agonist SR9009 (in normal saline containing 0.1% DMSO) was injected into hippocampal CA1 area at 1 h before laparotomy, with 2 μl on each side in group S+ SR9009.Morris water maze test was performed at 1 and 3 days after operation.Rats were sacrificed at 1 h after the end of Morris water maze test on day 3 after surgery, and the hippocampal tissues were obtained for determination of the expression of REV-ERBα, Brain and Muscle ARNT-Like 1 (BMAL1) protein, synaptophysin (SYN), postsynaptic density (PSD)-95 protein and N-methyl-D-aspartate receptor 2B subunit (GRIN2B) (by Western blot) and microscopic examination of the morphology of hippocampal neurons and Nissl bodies (by Nissl staining), and the viable neurons were counted. Results:Compared with group C, the percentage of time of staying at the target quadrant was significantly decreased, and the number of crossing platform was reduced on days 1 and 3 after exploratory laparotomy, the expression of REV-ERBα, BMAL1, PSD95, SYN and GRIN2B was down-regulated, and the number of viable neurons was decreased in group S and group SD ( P<0.05). Compared with group S and group SD, the percentage of time of staying at the target quadrant and the number of crossing platform were significantly increased on days 1 and 3 after exploratory laparotomy, the expression of REV-ERBα and PSD95 was up-regulated, the number of viable neurons was increased ( P<0.05), and no significant change was found in the expression of BMAL1, SYN and GRIN2B in group SS ( P>0.05). There was no significant difference in the indexes mentioned above between group S and group SD ( P>0.05). Conclusions:Activation of REV-ERBα can improve postoperative cognitive dysfunction, and the mechanism may be related to up-regulation of PSD95 expression in hippocampus and reduction of neuronal damage in rats.
ABSTRACT
Objective:To investigate the academic burnout level of nursing interns, and to analyze the influence path of nursing professional self-concept and professional values on the academic burnout of nursing interns.Methods:From September to December 2021, 204 nursing students who practiced for 6 months in the First Affiliated Hospital of Anhui Medical University were surveyed using the College Student Learning Burnout Scale, the Nursing Professional Self-Concept Scale and the Nursing Professional Values Scale. Structural equation modeling using AMOS 23.0.Results:The total score of academic burnout was (52.37 ± 11.60), which was in the middle level. The results of correlation analysis showed that the nurses' professional values were negatively correlated with depression, misbehavior, and low sense of achievement ( r=-0.253, -0.256, -0.406), and the differences were statistically significant ( P<0.01). Nursing professional self-concept was negatively correlated with depression, misbehavior, and low sense of achievement ( r=-0.466, -0.414, -0.525), and the differences were statistically significant ( P<0.01). Intern nursing students' nursing occupational self-concept had a partial mediating effect on their professional values and academic burnout, and the mediating effect accounted for 48.57% of the total effect. Conclusions:Professional values of nursing students can directly affect academic burnout, and also indirectly affect them through nursing professional self-concept.
