Objective To investigate the expression level and clinical significance of cyclic citrullinated peptide antigen-specific T cells(CCP/AST)in synovial fluid and synovial tissue of rheumatoid arthritis(RA)patients.Methods A total of 128 RA patients in Shijiazhuang Hospital of Traditional Chinese Medicine from January to December 2021 were selected as the RA group,and 50 patients who needed arthroscopy for joint pain in the hospital during the same period were selected as the control group.Among the RA group,there were 46 cases in the mild group,52 cases in the moderate group,and 30 cases in the severe group.The protein expression levels of rheumatoid factors(RF)and anticitrullinated protein antibodies(ACPA)in synovial tissues of the subjects in each group were analyzed by Western blot.The frequency of CCP/AST in the synovial fluid of the subjects was analyzed by flow cytometry.The intensity of the staining of CCP/AST in synovial tissues was observed by double immunofluorescence staining/laser confocal scanning.Pearson correlation analysis was used to assess the correlation between the CCP/AST expression of synovial fluid and synovial tissue and RF and ACPA.Logistic regression was used to analyze the risk factors for the development of rheumatoid arthritis.Results In the order of control,mild,moderate and severe groups,RF(1.01±0.01,1.53±0.03,2.01±0.08,2.66±0.12 kDa)and ACPA proteins(1.03±0.01,1.61±0.03,2.04±0.10,2.59±0.13 kDa)in synovial tissues of patients were sequentially elevated,and the differences were all statistically significant(F=14.207,12.446,all P＜0.05).The expression of CCP/AST in synovial fluid of patients in the control,mild,moderate and severe groups was increased sequentially(8.26%±1.68%,22.46%±3.28%,33.58%±4.37%,46.15%±5.44%),and the difference was statistically significant(F=25.306,P＜0.05).Meanwhile,the intensity of CCP/AST staining in synovial tissues of patients in the control,mild,moderate and severe groups was also increased sequentially(1.05±0.26,1.35±0.89,2.04±0.56,2.78±0.15 score),and the difference was statistically significant(F=70.67,P＜0.05).The expression of CCP/AST in the synovial fluid and synovial tissues of patients with RA was positively correlated with RF(r=0.861,0.934,all P＜0.05)and ACPA in synovial fluid and synovial tissue(r=0.854,0.913,all P＜0.05).Logistic regression analysis showed that hypertension(OR=3.241,95%CI:1.491～6.752),diabetes mellitus(OR=2.565,95%CI:1.126～5.813),synovial fluid(OR=4.450,95%CI:1.652～11.622),and CCP/AST expression in synovial tissues(OR=5.629,95%CI:2.474～12.390)were independent risk factors for the development of RA(P＜0.05).Conclusion CCP/AST showed high expression in synovial fluid and synovial tissue of RA patients and related to disease activity and joint destruction,which can be used to assess the clinical joint mobility and bone destruction degree in such patients.

Objective:To investigate the diagnosis and strategy of individualized functional rhinoplasty based on the overall evaluation of the nasal cavity as a integration.Methods:A prospective study was carried out in the patients who underwent endoscopic functional rhinoplasty at the Department of Otorhinolaryngology, the First Affiliated Hospital of Chongqing Medical University from February 2018 to August 2021. The overall evaluation of the internal and external structure and function of the nasal cavity was performed before surgery, and the individualized surgical strategies were developed. According to the surgical strategy, nasal septum correction, inferior turbinate ablation, inferior turbinate fracture displacement, inferior turbinate submucous resection, dorsal extended cartilage graft, crooked nose correction, prosthesis or autologous cartilage implantation, hump reduction and osteotomy were performed to adjust the nasal function and aesthetics. Internal nasal valve (INV) angle, INV collapse grade, INV cross-sectional area, and external nasal valve effectiveness (ENVE) index were used to evaluate the structure of nasal valve area. Nasal obstruction symptom assessment (NOSE) scale and nasal resistance [including total nasal resistance (RT), nasal resistance differential ratio (R 1r)] was used to evaluate nasal ventilation function. Facial clinimetric evaluation questionnaire rhinoplasty module (FACE-Q RM), rhinoplasty outcome evaluation (ROE) scale, external nasal subunit measurement was used to evaluate nasal appearance, and self-rating depression scale (SDS) and self-rating anxiety scale (SAS) was used to evaluate psychological status. Finally, the correlation between patient satisfaction and subjective and objective parameters were analyzed. The data before and after operation were compared by paired t-test. Correlation was tested by Pearson analysis. Results:A total of 50 patients were included, including 18 males and 32 females, ranging in age from 23 to 52 years, mean age 35.7 years. All patients had symptoms of nasal congestion, of which 28 cases with crooked nose deformity, 12 cases with nasal valve stenosis, 6 cases with saddle nose deformity, and 4 cases with hump nose. Compared with preoperative, postoperative INV angle was significantly increased, INV collapse grade was decreased, INV cross-sectional area was increased, ENVE index was increased ( P<0.05). After operation, the NOSE score decreased, and nasal resistance showed that RT and R 1r decreased, indicating that nasal congestion symptoms were relieved significantly ( P<0.05). The postoperative FACE-Q RM and ROE scores increased, indicating that patients’ nasal appearance satisfaction increased ( P<0.05), external nasal subunit measurement showed that the upper nasal alar width and lower nasal alar angle were reduced ( P<0.05), the measured value of residual structure has no significant change. Postoperative SDS and SAS scores were significantly lower than preoperative ones, and the difference was statistically significant ( P<0.05).Overall satisfaction was improved( P<0.05). Pearson correlation analysis showed that patient satisfaction was positively correlated with INV angle, INV cross-sectional area, ENVE index, and subjective nasal shape score (FACE-Q RM, ROE), and negatively correlated with INV collapse grade, NOSE score, and nasal resistance measurement, but had no correlation with external nasal subunit measurement. Conclusion:Combined with the overall evaluation of nasal structure, nasal ventilation function and external nasal aesthetics, it is beneficial to develop the diagnosis and treatment strategy of individualized functional rhinoplasty, so as to improve patient satisfaction.

Objective:To investigate changes in skin microecological structures and functions between acute and remission phases in adult patients with severe atopic dermatitis (AD) .Methods:From October 2019 to November 2020, skin scale specimens were collected from 5 body sites (cheeks, cubital fossa, back of the hand, abdomen, lower limbs) of 4 adult patients with severe AD in the acute and remission phases, who visited the outpatient clinic of Guangzhou Institute of Dermatology. The next-generation high-throughput sequencing was performed for metagenomic sequencing to construct the microbial gene catalogue of these specimens, followed by gene annotation and bioinformatics analysis for each sample.Results:A total of 18 phyla, 37 classes, 73 orders, 142 families, 237 genera, and 331 species were identified in the skin specimens from the 4 patients with severe AD. The patients with AD in the remission phase showed significantly increased diversity of skin microbiota and markedly different relative abundance of skin microorganisms compared with those in the acute phase (both P < 0.05). At the microbial species level, Staphylococcus aureus showed the highest impact on the acute phase of AD, while Staphylococcus epidermidis, Moraxella osloensis, Francisella sp., Staphylococcus cohnii, Staphylococcus warneri, Malassezia globosa and Malassezia restricta were enriched in the remission phase of AD with the absolute value of the common logarithm of the linear discriminant analysis score > 2 (Kruksal-Wallis test, all P < 0.05). As KEGG pathway enrichment analysis showed, the differentially abundant genes were annotated into a total of 355 functional pathways, of which 38 pathways were significantly enriched (all P < 0.05), mainly involving Staphylococcus aureus infection, tryptophan metabolism, histidine metabolism, nitrogen metabolism, metabolism of arginine and proline, biosynthesis and degradation of valine, leucine and isoleucine, fatty acid degradation, peroxisome proliferator-activated receptor signaling pathway, etc. Conclusion:The skin microecological structure significantly differed between the acute and remission phases among the patients with severe AD, which may be related to multiple functional pathways, such as Staphylococcus aureus infection, tryptophan metabolism, histidine metabolism and nitrogen metabolism.

Objective:To explore the application effect of quality control rehabilitation nursing in patients with dysphagia after acute stroke.Methods:A total of 122 patients with dysphagia after acute stroke who were admitted to Bozhou People's Hospital from April 2018 to March 2021 were selected as the research objects by the convenient sampling method. According to the random number table method, they were divided into the observation group and the control group, with 61 cases in each group. The control group was given routine rehabilitation nursing, while the observation group was given quality control rehabilitation nursing on this basis. Standardized Swallowing Assessment (SSA) and Swallow Quality-of-Life Questionnaire (SWAL-QOL) were used to evaluate the intervention effect.Results:Among the 122 patients, 3 patients died, 2 patients voluntarily gave up treatment and 2 patients were excluded from the study due to other reasons. A total of 115 patients were included, including 58 in the observation group and 57 in the control group. After intervention, the SSA score of the observation group was lower than that of the control group and the SWAL-QOL score was higher than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Quality control rehabilitation nursing can improve the swallowing function and quality of life of patients with dysphagia after acute stroke.

Objective:To explore the status and influencing factors of incontinence-associated dermatitis among elderly inpatients in 52 hospitals nationwide, and to analyze the nursing of elderly inpatients with incontinence, so as to provide a reference for clinical intervention.Methods:On March 31, 2021, convenience sampling was used to select 14 675 elderly inpatients from 52 hospitals across the country as the research object. The self-designed Incontinence-associated Dermatitis Questionnaire for Elderly Inpatients was used to collect general demographic data, health status, incontinence, and skin nursing. Binomial Logistic regression was used to investigate the influencing factors of incontinence-associated dermatitis in elderly inpatients.Results:Among 14 675 elderly inpatients, the prevalence rates of xerosis cutis, incontinence and incontinence-associated dermatitis were 38.78% (5 691/14 675) , 11.06% (1 623/14 675) and 1.91% (280/14 675) , respectively. The prevalence of mild, moderate and severe incontinence-associated dermatitis were 1.27% (186/14 675) , 0.55% (81/14 675) , and 0.09% (13/14 675) , respectively. Among the nursing of 1 623 elderly inpatients with incontinence, the items with low implementation rate were the use neutral lotion to clean skin (14.17%, 230/1 623) , use of skin protectant after moisturizing (17.68%, 287/1 623) , moisturizing after cleansing the skin (28.90%, 469/1 623) . The results of binomial Logistic regression analysis showed that xeroderma, fecal incontinence, urinary and fecal incontinence, ≥2 kinds of combined medication, and hospital stay >30 days were risk factors for incontinence-associated dermatitis in elderly inpatients.Conclusions:The risk factors of incontinence-associated dermatitis in elderly inpatients mainly include xerosis cutis, type of incontinence, ≥2 kinds of combined medication, and hospital stay >30 days.

Objective:To observe the clinical efficacy, safety, compliance, and cost-effectiveness of rush immunotherapy (RIT) and conventional immunotherapy (CIT) in patients with allergic rhinitis (AR), so as to evaluate the clinical significance of CIT and preliminarily explore its economic value.Methods:A study was conducted on 72 AR patients who had received specific immunotherapy from Oct 2019 to Jun 2020 in the Department of Otorhinolaryngology, the First Affiliated Hospital of Chongqing Medical University, including 39 males and 33 females, aging 8 to 60 years. RIT or CIT was performed respectively according to the patients′ wishes. There were 35 cases in the RIT group and 37 cases in the CIT group, all subjects were followed up for 1 year. Visual analysis scale (VAS) and effectiveness were used to evaluate the clinical efficacy. Systemic adverse reactions were used to assess safety. Failure rate was calculated to evaluate the compliance. The cost and cost-effectiveness ratio (CER) were conducted to evaluate the health economics preliminarily.Results:After half a year and one year′s treatment, both RIT and CIT groups had significant clinical efficacy and RIT group had more significant clinical efficacy than CIT group at half a year (76.67% vs 46.67%, χ 2=7.37, P=0.007). During the dose accumulation phase, there was no significant difference in the incidence of systemic adverse reactions between the two groups (8.57% vs 8.10%, χ 2=0.05, P=0.943), while the drop-out rate in the RIT group was significantly lower than that in the CIT group (0 vs 13.51%, χ 2=5.08, P=0.024). After one year, the costs in RIT group were significantly higher ((8 163.08±452.67) yuan vs (7 385.87±369.92) yuan, t=-2.78, P=0.009), while there was no statistical differences in CER between the two groups ((3 298.06±1 374.09) yuan/point vs (3 154.38±1 532.51) yuan/point, t=-0.36, P=0.418). Conclusions:Both RIT and CIT are beneficial for AR, and they have similar clinical efficacy, safety, and CER. RIT is more effective in the early stage, with higher patient compliance. Thus, RIT is worth promoting and exploring in clinic.

Objective:To explore the subjective and objective evaluation methods in functional rhinoplasty.Methods:Sixty-four patients who underwent rhinoplasty in the Department of Otorhinolaryngology, the First Affiliated Hospital of Chongqing Medical University were included in this study from January 2017 to October 2018. There were 32 males and 32 females, with the age ranging from 18 to 45 years old. Before and 6 months after operation, nasal ventilation function was evaluated by Visual Analogue Scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE), nasal acoustic reflex and nasal resistance. Satisfaction with nasal appearance was evaluated by VAS, Rhinoplasty Outcome Evaluation (ROE) and facial proportions evaluation. Psychological state was assessed by Emotional Balance Scale and Rosenberg Self-esteem Scale. Finally, the Pearson correlation analysis of patient satisfaction was performed. SPSS 23.0 software was used for statistical analysis. Results:Compared with pre-operation, nasal obstruction VAS, NOSE scores, total nasal resistance and difference ratio of nasal resistance showed significantly decline after surgery (1.62±0.85 vs 7.56±1.44, 22.62±3.54 vs 69.75±7.85, (0.16±0.08) Pa·s/ml vs (0.31±0.43) Pa·s/ml, 0.33±0.28 vs 0.71±0.32, all P<0.05). VAS of appearance and ROE scores showed an increase after surgery (11.20±3.66 vs 2.70±0.97, 17.80±2.71 vs 7.50±1.12, all P<0.05). The measurement of the external nasal subunits showed that the length of the dorsum of the nose, the angle of the face to the nose, the angle of the frontal and the angle of the alar of the nose were obviously reduced ((29.33±4.26) mm vs (33.61±5.24) mm, (135.11±3.81)° vs (139.91±6.30)°, (130.63±2.88)° vs (136.74±5.72)°, (99.71±4.02)° vs (106.27±5.60)°, all P<0.05). The scores of postoperative Emotional Balance Scale and Rosenberg Self-esteem Scale increased significantly (5.88±1.54 vs 4.31±1.85, 28.31±2.64 vs 22.13±2.77, all P<0.05). The Pearson correlation analysis showed that patients′ satisfaction was positively correlated with subjective score of nasal ventilation (VAS, NOSE), subjective score of nasal appearance (VAS, ROE) and emotional balance scale, while negatively correlated with nasal resistance, and not correlated with the measurement of external nasal subunit. There was a significant positive correlation between the subjective score of nasal ventilation and the measurement of nasal resistance, but there was no significant correlation between the subjective score of nasal appearance and the measurement of external nasal subunit. Conclusion:The subjective and objective evaluation of nasal ventilation function, aesthetics of nasal appearance and psychological state can evaluate the effect of functional rhinoplasty effectively.
