Objective In this study,the potential profile characteristics of exercise self-efficacy of patients with inflammatory bowel disease(IBD)were explored,and the influencing factors of different types of patients were an-alyzed,so as to provide a reference for nurses to formulate standardized management measures.Methods From June 2023 to May 2024,a total of 342 hospitalized patients with IBD in tertiary A hospital in Wuxi were recruited as research subjects by a convenience sampling method.The General Information Questionnaire,Exercise Self-effica-cy Scale,Exercise Behavioral Stage Distribution Scale and the Social Support Rating Scale were used for investiga-tion.The latent profile analysis was conducted to classify exercise self-efficacy levels,while multiple Logistic regres-sion analysis was utilized to evaluate the influencing factors.Results A total of 320 valid questionnaires were col-lected,and the effective questionnaire recovery rate was 93.57％.The total score of exercise self-efficacy for IBD pa-tients was(64.61±14.83)points.The exercise self-efficacy was classified into 3 latent categories:low efficacy-somatic emotion group(n=64,20.00％),medium efficacy-work conflict group(n=158,49.38％),and high efficacy-social interfer-ence group(n=98,30.62％).Occupation,recurrence times,comorbid chronic diseases,self-assessed economic pressure,and social support level were found to be influencing factors of the latent profile classification of exercise self-effi-cacy in IBD patients(P＜0.05).Conclusion The levels of exercise self-efficacy of patients with IBD are significant-ly heterogeneous,and there are several important influencing factors.Nursing staff should formulate targeted inter-vention strategies based on the characteristics of exercise self-efficacy in such patients,so as to improve patients' exercise self-efficacy and the effectiveness of disease rehabilitation.

Objective:To explore the efficacy and prognosis of preoperative treatment based on arterial infusion chemotherapy (PTAC) in patients with advanced gastric cancer.Methods:Clinical and follow-up data of 821 patients with advanced gastric cancer who received PTAC treatment at the General Hospital of the Eastern Theater Command of the People's Liberation Army from January 2001 to January 2021 were collected. According to the treatment regimen, patients were divided into the FLEEOX group (89 cases), the XEEOX group (196 cases), the SEEOX group (406 cases), and the SEEOX+PD-1 group (130 cases). The primary endpoint was the 3-year progression-free survival rate. Secondary endpoints included the 3-year overall survival rate, objective response rate, radical resection rate, major pathological response rate, and incidence of treatment associated adverse events.Results:After PTAC treatment, the objective response rate was 74.9% (615/821). A total of 671 patients underwent radical surgery, with a radical resection rate of 81.7% and an R0 resection rate of 70.2% (576/821). The pathological complete response rate was 16.7% (112/671), and the major pathological response rate was 32.2% (216/671). With an average follow-up of 27.7 months, the 3-year progression-free survival rate was 52.2%, and the 3-year overall survival rate was 55.8%. The 3-year progression-free survival rate of patients in the SEEOX+PD-1 group was 66.9%, the objective response rate was 83.8% (109/130), the major pathological response rate was 45.3% (53/117), and the radical resection rate was 90.0% (117/130), all of which were better than those in the XEEOX and SEEOX groups (all P＜0.05). However, during the treatment period, three patients in the SEEOX+PD-1 group died from immune-related adverse events. Conclusion:PTAC treatment is an effective preoperative treatment method for advanced gastric cancer, and is expected to further improve the treatment effect when combined with immunotherapy such as PD-1 monoclonal antibodies.

The clinical phenotype heterogeneity of epilepsy patients with ADGRV1 gene mutation is significant, ranging from self limiting febrile seizures to developmental epileptic encephalopathy, even causing sudden epileptic death. A case of infantile epileptic spasms syndrome with a novel heterozygous variant of the ADGRV1 gene c.4100C>A (p.Thr1367Lys) was reported in this article. The site of this variant had not been reported yet, and the clinical manifestations of the child mainly included epileptic spasms (first onset at 4 months old), mild growth and development delay, highly irregular video electroencephalogram, and effective treatment with adrenocorticotropic hormone.

In order to establish a method for the detection of serum antibodies to donkey-derived e-quine coronavirus(ECoV),recombinant ECoV N protein was expressed in E.coli system,purified by nickel column affinity chromatography and identified by Western blot.After optimizing the re-action conditions,the indirect ELISA(iELISA)detection method was established using the puri-fied recombinant protein as coating antigen and used to detect 143 clinical serum samples.The re-sults showed that the recombinant N protein,which has good reaction activity with serum antibod-y,was successfully expressed.The optimum conditions of the established iELISA method were as follows:the amount of antigen coated was 0.2 μg/well and overnight at 4 ℃,10％skimmed milk powder solution was sealed at 37℃ for 1.5 h,the dilution concentration of serum was 1∶200,and the enzyme-labeled secondary antibody diluted at 1∶10 000.The sensitivity test results showed that the positive serum could be diluted to 1∶6 400.The specificity test results showed that all an-tibodies to several donkey pathogens were negative.The repetitive test results showed that the in-tra-and inter-batch coefficients of variation were 2.90％-6.12％and 2.29％-7.88％respectively.The positive rate of clinical donkey serum was 57.3％.The iELISA established in this study pro-vides a technical support for epidemiological investigation and antibody surveillance.

Objective:To determine appropriate cutoff values for evaluating hypoxemia severity in patients with obstructive sleep apnea (OSA).Methods:This cross-sectional study selected data from 1, 781 young patients with obstructive sleep apnea (OSA) who underwent polysomnography in the Department of Otorhinolaryngology Head and Neck Surgery of the Sixth Medical Center of PLA General Hospital from January 2015 to June 2023. The cohort included 1, 604 males and 177 females, with a mean age of (32.6±5.3) years. The relationship between the minimum arterial oxygen saturation (MSaO 2) and the prevalence of hypertension in this population was investigated. Subjects were categorized into seven groups based on MSaO 2 levels: Group 1 (MSaO 2≥90%), Group 2 (85%≤MSaO 2<90%), Group 3 (80%≤MSaO 2<85%), Group 4 (75%≤MSaO 2<80%), Group 5 (70%≤MSaO 2<75%), Group 6 (65%≤MSaO 2<70%), and Group 7 (MSaO 2<65%). The prevalence of hypertension in each group was statistically analyzed, and the chi-square test was used to identify significant differences in hypertension prevalence. The diagnostic performance of the new versus traditional grouping methods was evaluated using receiver operating characteristic (ROC) curve analysis. Results:Among the 1, 781 OSA patients, 915 had hypertension. The prevalence of hypertension in Groups 1 to 7 was 27.8%, 42.4%, 52.2%, 54.1%, 59.5%, 70.5%, and 75.4%, respectively. Significant differences in hypertension prevalence were observed between Group 1 and other groups, Group 2 and Groups 5-7, Group 3 and Groups 6-7, and Group 4 and Group 7( χ2=187.94, P<0.001). After merging the groups based on MSaO 2 thresholds of≥90%, 90%>MSaO 2≥85%, 85%>MSaO 2≥75%, and MSaO 2<75%, the prevalence of hypertension in the new groups was 27.8%, 42.4%, 53.0%, and 71.2%, respectively, with significant differences between adjacent groups( χ2=178.99, P<0.001). ROC curve analysis revealed that the area under the curve (AUC) for the new grouping method (0.676) was higher than that for the original grouping method (0.664). Conclusions:As hypoxemia severity increases in OSA, so does the prevalence of comorbid hypertension. Using MSaO 2 cutoff values of 90%, 85%, and 75% to categorize hypoxemia severity appears more appropriate compared to the existing guideline values of 90%, 85%, and 80%.

Objective:To study the characteristics of laryngopharyngeal reflux (LPR) events in patients with obstructive sleep apnea (OSA).Methods:This cross-sectional study analyzed OSA patients who were admitted in the Department of Otolaryngology-Head and Neck Surgery, the Sixth Medical Center of the Chinese PLA General Hospital between November 2020 to July 2023[OSA group, 52 males, 6 females, aged 23-69 (41.22±11.42) years], and non-OSA patients admitted during the same period serve as the control group[non-OSA group, 40 males, 1 female, aged 21-68 (45.12±11.30) years]. All participants completed the Reflux Symptom Index (RSI), Reflux Finding Score (RFS) scale, and 24-hour Hypopharyngeal Esophageal Multichannel Intraluminal Impedance-pH (HEMII-pH) monitoring. LPR events were categorized based on their physical composition-liquid, gas, or gas-liquid mixed, according to the change of impedance values; and further classified by pH levels as acidic, weakly acidic, or alkaline. Differences in LPR events physical properties and the time trends of LPR events between the two groups were compared. Group comparisons were performed using t-test or Mann-Whitney U-test. Analyses were conducted using Pearson, Spearman, or Kendall′s tau-b correlation analysis. Categorical data were analyzed using chi-square test. Results:A total of 99 patients were enrolled, including 58 with OSA and 41 without OSA. Of these, 88.89% (88/99) met the diagnostic criteria for laryngopharyngeal reflux disease (LPRD). In LPRD patients, the median proportion of non gas reflux events and the number of alkaline reflux were significantly higher in the OSA with LPRD group than in the non OSA with LPRD group (70.00% vs 36.36%, 0 vs 0, Z-values respectively -3.373, -3.134, P<0.01). Liquid reflux proportion and the number of both liquid and mixed reflux events showed a positive correlation with the apnea-hypopnea index (AHI) ( r-values respectively 0.304, 0.326, 0.268, P<0.05), while the gas reflux constituent ratio was inversely correlated with AHI ( r=-0.358, P<0.01). The frequency and proportion of nocturnal reflux events showed a positive correlation with AHI ( r-values respectively 0.250, 0.211, P<0.05). A significantly higher proportion of OSA with LPRD group experienced both daytime and nighttime reflux compared to non OSA with LPRD group (66.67% vs 38.71%, P<0.05). In LPRD patients, over 50% of all LPR events occurred within 3 hours after each of the three main meals. Conclusions:In OSA with LPRD patients, LPR events are predominantly non gas in nature. OSA with LPRD patients exhibits a higher proportion and frequency of nocturnal reflux events and a greater number of alkaline reflux episodes compared to non OSA with LPRD patients.

BACKGROUND:The combination of traditional Chinese medicine syndrome and semen quality-related parameters can jointly predict the occurrence of abnormal increase in sperm DNA fragmentation index (DFI) and draw a column chart,which can significantly improve clinical practicality and application efficiency,provide a basis for comprehensive evaluation of semen quality in clinical practice,take active intervention measures to improve clinical outcomes,and formulate personalized medical plans.OBJECTIVE:To explore the prediction model and verification of sperm DNA fragments based on traditional Chinese medicine syndrome and semen quality-related parameters.METHODS:Retrospective analysis was made on 420 infertile patients who received traditional Chinese medicine syndrome diagnosis and sperm DNA fragment rate examination in the Department of Traditional Chinese Medicine Andrology,Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2019 to July 2021.According to the Manual of Human Semen Examination and Treatment Laboratories (6th Edition),137 patients with sperm DFI>30％ were included in the group of abnormally high sperm DFI,and 283 patients with sperm DFI ≤ 30％ were taken as the control group.First,univariate analysis was used to screen the influencing factors of the abnormal increase of sperm DFI.Then,the best matching factor was selected by using the collinearity problem of LASSO correction factors.Then,it was included in the multifactor forward stepwise logistic regression to find out its independent influencing factors and draw a nomogram.Finally,the receiver operating characteristic curve,calibration curve,decision curve analysis and clinical impact curve were used to verify the differentiation and accuracy of the prediction model and its clinical application effectiveness.RESULTS AND CONCLUSION:(1) The results of the univariate analysis showed that age,body mass index,forward motion rate,total sperm motility,sperm concentration,sperm morphology,kidney yang deficiency syndrome,damp heat downpour syndrome,and kidney sperm deficiency syndrome were the influencing factors for the abnormal increase of sperm DFI (P<0.05).(2) The best matching factors further screened by LASSO regression were age,body mass index,total sperm motility,sperm concentration,sperm morphology,kidney yang deficiency syndrome,damp heat downpour syndrome,and kidney essence deficiency syndrome (P<0.05).(3) Multifactor forward stepwise Logistic regression showed that age,body mass index,sperm concentration,total sperm motility,damp heat downpour syndrome,and kidney yang deficiency syndrome were six independent factors that caused the abnormal increase in sperm DFI.(4) Receiver operating characteristic curve showed that the area under the curve of the model group was 0.760(0.713,0.806),and the area under the curve of the validation group was 0.745(0.714,0.776).It showed that the prediction model had good discrimination.(5) The average absolute error of the calibration curve was 0.040,and the Hosmer Lemeshow test (P>0.05),suggesting that there was no significant statistical difference between the probability of the abnormal increase in DFI of spermatozoa predicted by the model and the probability of the abnormal increase in DFI of spermatozoa actually occurred,which confirmed that the model had good accuracy.(6) Decision curve analysis and clinical impact curve showed that the model group and validation group had the maximum clinical net benefit when the threshold probability values were (0.08-0.84) and (0.09-0.78) respectively,and had good clinical application efficiency within the threshold probability range.(7) These findings conclude that age,body mass index,sperm concentration,total sperm viability,damp heat downpour syndrome and kidney yang deficiency syndrome are independent factors that cause the abnormal increase in sperm DFI.The nomogram of the clinical prediction model constructed by them has good clinical prediction value and clinical application efficiency,and can provide the basis for comprehensive clinical evaluation of semen quality and individualized medical service.

Objective:A retrospective analysis was conducted on the clinical characteristics and polysomnography (PSG) features of patients with obstructive sleep apnea (OSA) of different ages.Methods:From January 2015 to March 2024, the patients who underwent overnight PSG monitoring at the Sleep Respiratory Disease Diagnosis and Treatment Center, Department of Otolaryngology, Head and Neck Surgery, Sixth Medical Center of the PLA General Hospital were sequentially enrolled.A total of 4 396 patients[aged from 18 to 97(46.04±12.60)years] with OSA who met the criteria were finally enrolled and divided into the youth group (18-44 years old, n=2 099), middle-aged group (45-59 years old, n=1 641), and elderly group (≥60 years old, n=656).The differences in general condition, Epworth sleepiness Scale (ESS) score, rapid eye movement sleep (REM) sleep time in total sleep time, micro-awakening index, apnea hypopnea index (AHI), minimum oxygen saturation at night (LSpO 2), oxygen hypoxia index (ODI) and so on were compared.Multivariate Logistic regression was used to analyze the relationship between age stratification and different severity of OSA (mild 5≤AHI≤15, moderate 1530, Times per hour). Results:The neck circumference [(39.11±3.71) cm], body mass index [BMI, (26.63±3.70) kg/m2], total sleep time [(386.13±66.09) min], the percentage of deep sleep in total sleep time [(3.05±4.80)%], the percentage of REM sleep time in total sleep time [(16.73±6.83)%], apnea-hypopnea index [AHI, (31.17±19.20) events/h], oxygen desaturation index [ODI, (46.57±33.54) events/h], microarousal index [(14.82±12.27) events/h], and Epworth Sleepiness Scale (ESS) score (8.29±5.92) in the elderly group were all lower than those in the young group [neck circumference (41.36±3.37) cm, BMI (28.55±4.21) kg/m2, total sleep time [(424.67±62.21) min], the percentage of deep sleep in total sleep time (5.89±6.79)%, the percentage of REM sleep time in total sleep time (17.95±6.67)%, AHI (39.55±27.89) events/h, ODI (61.88±34.60) events/h, microarousal index (22.77±19.31) events/h, ESS score (9.63±5.82)] and the middle-aged group [neck circumference (40.75±3.59) cm, BMI (27.89±3.55)kg/m2, total sleep time [(410.98±63.02)min], the percentage of deep sleep in total sleep time (3.59±5.11)%, the percentage of REM sleep time in total sleep time (17.47±6.63)%, AHI (36.01±23.63) events/h, ODI (57.20±34.75) events/h, microarousal index (19.23±15.59) events/h, ESS score (9.98±6.11)], with F values of 102.62, 62.15, 95.87, 95.94, 8.71, 29.60, 49.72, 59.11, and 19.03, respectively, and all P values were <0.001. The proportion of females [29.57% (94/656)], the proportion of patients with hypertension [37.20% (244/656)], and the nocturnal LSpO 2 [(79.09±9.88)%] in the elderly group were all higher than those in the young group [proportion of females [6.48% (136/2 099)], proportion of patients with hypertension 18.10% (380/2 099), nocturnal LSpO 2(75.19±12.90)%] and the middle-aged group [proportion of females [15.84%(260/1 641)], proportion of patients with hypertension 33.09% (543/1 641), nocturnal LSpO 2(76.15±12.44)%], with F values of 242.62, 150.90, and 25.05, respectively, and all P values were <0.001.There were no significant differences in neck circumference, percentage of REM sleep time in total sleep time, AHI and LSpO 2 at night between young and middle-aged groups ( P>0.05). After adjusting for gender, neck circumference, BMI, and hypertension confounders, the risk of severe OSA in the older group was increased by 27.4% compared with the younger group ( OR=1.274, 95% CI=1.036-1.566, P<0.05). Further stratified analysis showed that neck circumference and BMI were independent factors for severe OSA in the young and middle-aged groups ( P<0.01), while, only neck circumference was independently associated with severe OSA in the elderly group (OR=1.119, 95% CI=1.039-1.207, P<0.01). Conclusion:The severity of OSA in young and middle-aged patients is more serious than that in elderly patients. Obesity is an important factor affecting the degree of OSA in young and middle-aged patients. After controlling for confounding factors such as obesity, the risk of severe OSA in elderly patients is higher than that in young patients, which is considered to be related to factors such as pharyngeal collapse and relaxation of pharyngeal muscles.

AIM: To analyze the value of blue-on-yellow perimetry(B/Y)combined with macular ganglion cells inner plexiform layer(GCIPL)detection in the early diagnosis of open angle glaucoma.METHODS: A prospective case-control study was conducted to collect 100 patients(174 eyes)from May 2023 to May 2024 in Eye Hospital of Wenzhou Medical University as the case group, and 20 healthy volunteers(40 eyes)as the control group. The case group was divided into high intraocular pressure group, suspected glaucoma group, and early glaucoma group based on the examination results. All study subjects underwent comprehensive ophthalmic examination, white-on-white perimetry(W/W)and B/Y examination, and swept source optical coherence tomography(SS-OCT)was used to scan the optic disc and macula to obtain relevant parameters. The value of B/Y combined with macular GCIPL in the diagnosis of open angle glaucoma was analyzed.RESULTS: In the case group, 30 cases(52 eyes)were diagnosed with early primary open angle glaucoma, 46 cases(82 eyes)were suspected of open angle glaucoma, and 24 cases(40 eyes)were diagnosed with high intraocular pressure. The W/W mean defect(MD)and B/Y-MD values in the early glaucoma group were lower than those in the control group, high intraocular pressure group, and suspected glaucoma group. The W/W pattern standard deviation(PSD)and B/Y-PSD values were higher than those in the control group, high intraocular pressure group, and suspected glaucoma group(all P<0.05). The W/W-MD and B/Y-MD values in the suspected glaucoma group were lower than those in the control group and the high intraocular pressure group(all P<0.05). The B/Y-MD values in the high intraocular pressure group were lower than those in the control group(P<0.05). The parameters of GCIPL in the macular area of the early glaucoma group were lower than those of the control group, high intraocular pressure group, and suspected glaucoma group(all P<0.05). The minimum GCIPL in the macular area of the suspected glaucoma group, as well as the upper and lower temporal areas, were lower than those of the control group and the high intraocular pressure group(all P<0.05). The average, upper, lower, temporal, 5:00, 6:00, and 12:00 positions of the retinal nerve fiber layer(RNFL)parameters around the optic disc in the early glaucoma group were lower than those in the control group, high intraocular pressure group, and suspected glaucoma group(all P<0.05). The average and upper RNFL parameters in the suspected glaucoma group were lower than those in the control group and high intraocular pressure group. The rim area of the optic nerve head(ONH)parameters in the early glaucoma group was smaller than that in the control group, high intraocular pressure group, and suspected glaucoma group, while the horizontal and vertical cup-to-disc ratio was higher than those in the control group, high intraocular pressure group, and suspected glaucoma group; the rim area of the suspected glaucoma group was smaller than that of the control group and high intraocular pressure group, and the horizontal and vertical cup-to-disc ratio were higher than those of the control group and high intraocular pressure group(all P<0.05). Receiver operating characteristic(ROC)curve was drawn, and the results showed that visual field parameters, macular GCIPL parameters, and RNFL parameters had certain diagnosibility for early open angle glaucoma and suspected glaucoma. Decision curve was drawn, and the results showed that when the threshold was between 0 and 1.0, the net return rate of diagnosing early open angle glaucoma with the combination of B/Y and macular GCIPL parameters was higher than the individual diagnostic efficacy of each indicator.CONCLUSION: The combination of B/Y and macular GCIPL detection can be an important means for the early diagnosis of glaucoma.
