AIM: To evaluate the efficacy of 0.05% cyclosporine eye drops in promoting ocular surface recovery following pterygium excision combined with autologous corneal limbal stem cell transplantation.METHODS:This study is a prospective randomized controlled trial, selecting 104 cases(104 eyes)of primary pterygium with monocular onset admitted to Baoding First Central Hospital from September 2023 to September 2024 as the initial sample. The patients were divided into an experimental group and a control group using a random number table method, with 52 eyes in each group. Both groups underwent pterygium excision and autologous corneal limbal stem cell transplantation performed by the same surgeon. The control group received tobramycin dexamethasone eye drops combined with 0.3% sodium hyaluronate eye drops, while the experimental group was additionally treated with 0.05% cyclosporine eye drops. The corneal epithelial repair status, ocular surface function [corneal fluorescein staining(FL)score, Schirmer I test(SIt), break-up time of tear film(BUT)] at preoperative and postoperative time points(1 and 3 mo), and dry eye symptoms [ocular surface disease index(OSDI), standard patient evaluation of eye dryness(SPEED)scores]. Additionally, the recurrence rate and postoperative complications were recorded.RESULTS: During the follow-up period, there was 1 case of loss to follow-up in both the experimental group and the control group, with lost to follow-up rate of 1.9%. Finally, 51 cases in each group completed all followed-up. No statistically significant difference was observed in preoperative general characteristics of patients between the two groups(P>0.05), and there was no statistically significant difference in corneal epithelial repair time or suture removal time(all P>0.05). At 1 mo postoperatively, the SIt and BUT decreased in both groups compared to preoperative levels, with the experimental group showing higher values than the control group(all P<0.05). FL scores increased compared to preoperative levels but were lower in the experimental group(all P<0.05). By 3 mo, the SIt, BUT and FL score of the control group were not statistically different from preoperative levels(all P>0.05), whereas the experimental group showed increased SIt and BUT, which were higher than the control group, and reduced FL scores, and decreased FL scores, which was lower than the control group(all P<0.05). At 3 mo postoperatively, both groups showed increased SIt and BUT compared to 1-month values, with the experimental group outperforming the control group(all P<0.05). FL scores decreased in both groups compared to 1-month values, with the experimental group maintaining lower scores(P<0.05). At 1 mo postoperatively, OSDI and SPEED scores were higher than preoperative levels, with the experimental group higher than the control group(all P<0.05); at 3 mo postoperatively, the scores returned to preoperative level(all P>0.05), and the OSDI and SPEED scores of the control group increased and higher than those of the experiment group(all P<0.05); at 3 mo postoperatively, the OSDI and SPEED scores decreased when compared with 1-month preoperative level, and the experiment group was lower than the control group(all P<0.05). There was no difference in the total incidence of postoperative complications between the two groups(P>0.05). According to the statistics of 6 mo follow-up after operation, there was no recurrence in the experimental group, and the recurrence rate was 11.8% in the control group(P<0.05).CONCLUSION: Adjunctive use of 0.05% cyclosporine eye drops after pterygium excision with limbal stem cell transplantation enhances ocular surface recovery, reduces dry eye symptoms, and lowers recurrence rates without compromising corneal epithelial healing or safety.

Objective:To explore the mediating role of psychological resilience between work stress and sleep quality in psychiatric nurses.Methods:From April to August 2023, convenience sampling was used to select 457 psychiatric nurses working in three psychiatric hospitals in Henan Province as the research subjects. The survey was conducted using the General Information Questionnaire, the Chinese version of the Connor-Davidson Resilience Scale (CD-RISC), the Chinese Nursing Stressor Scale (CNSS), and the Pittsburgh Sleep Quality Index (PSQI). Pearson correlation was used to analyze the correlation between psychological resilience, work stress, and sleep quality among psychiatric nurses. SPSS 26.0 software was used to analyze the data, and Process macro program and Bootstrap method were used to test the mediating effect.Results:Among 457 psychiatric nurses, the total scores of the Chinese version of CD-RISC, CNSS, and PSQI were (58.89±13.27), (78.02±14.31), and (8.04±3.46), respectively. Pearson correlation showed that work stress was positively correlated with sleep quality ( r=0.703, P<0.01). In contrast, work stress was negatively correlated with psychological resilience ( r=-0.413, P<0.01), and psychological resilience was negatively correlated with sleep quality ( r=-0.712, P<0.01). Psychological resilience partially mediated the relationship between work stress and sleep quality, with a mediating effect value of 0.051, accounting for 30.0% of the total effect. Conclusions:Psychological resilience partially mediates the relationship between work stress and sleep quality in psychiatric nurses. Nursing managers should attach importance to and enhance the psychological resilience of psychiatric nurses, regularly relieve stress, improve sleep quality, and enhance the physical and mental health of nurses.

Objective:To explore the different categories of family resilience in cervical cancer patients and their influencing factors.Methods:From October 2022 to September 2023, 275 cervical cancer patients admitted to the First Hospital of Shanxi Medical University were selected as the study subject by convenience sampling. Cervical cancer patients were surveyed using the self-made General Information Questionnaire, Benefit Finding Scale (BFS), Connor-Davidson Resilience Scale (CD-RISC), and shortened Chinese Version of the Family Resilience Assessment Scale (FRAS-C). Latent profile analysis was used to investigate the family resilience of patients, and Logistic regression was used to analyze the influencing factors of family resilience in different categories.Results:A total of 275 questionnaires were distributed, and 253 valid questionnaires were collected, with a valid response rate of 92.0% (253/275). Family resilience of cervical cancer patients was divided into three categories of low resilience-negative coping group (18.6%, 47/253), moderate resilience-communication disorder group (59.3%, 150/253), and high resilience-inclusive understanding group (22.1%, 56/253). The per capita family monthly income, place of residence, primary caregivers, whether to undergo radiotherapy or chemotherapy, psychological resilience, and disease benefit finding were the influencing factors of family resilience in different categories of cervical cancer patients ( P<0.05) . Conclusions:The family resilience of cervical cancer patients can be divided into three latent categories. Medical and nursing staff should identify the characteristics of different categories of patients and provide targeted intervention measures to improve their family resilience.

The paper reports a case of 2,8-dihydroxyadenine (2,8-DHA) crystalline nephropathy caused by mutation of adenine phosphoribosyltransferase ( APRT) gene. The female patient was 60 years old, and sought medical advice due to "foaming urine increased for half a year". Renal biopsy result showed irregular yellowish brown 2,8-DHA crystals with refraction under polarized light. 2,8-DHA crystals were found by urine sediment detection, and homozygous deletion of c.521_523delTCT on exon 5 of APRT gene was found by genetic testing. Finally this patient was diagnosed as 2,8-DHA crystalline nephropathy. Renal function improved after treatment with allopurinol. The case report aims to improve the clinician's understanding of 2,8-DHA crystalline nephropathy. Early recognition, correct diagnosis, and early drug intervention may delay the progression of renal failure and improve the prognosis.

Objective:To investigate the application effect of E-learning digital platform combined with brainstorming teaching in nursing practice teaching of otolaryngology and head and neck surgery.Methods:A total of 41 nursing students who received practice teaching in Qilu Hospital of Shandong University from January 2022 to June 2022 were selected as control group, and 39 nursing students who received practice teaching from July 2022 to December 2022 were selected as observation group. The students in the control group received traditional nursing teaching, while those in the observation group received brainstorming teaching based on the E-learning digital platform. After teaching, the two groups were compared in terms of academic performance, daily problem-solving ability, self-learning ability, critical thinking ability, and degree of satisfaction with teaching. SPSS 24.0 was used to perform the chi-square test and the t-test. Results:Compared with the control group, the observation group had significantly higher theoretical and operational assessment scores [(90.11±5.43)/(88.19±5.33) vs. (82.67±5.09)/(81.33±4.27)], scores of positive problem-solving orientation and rational problem-solving dimensions of the problem-solving questionnaire, scores of each dimension of the self-learning ability scale and the critical thinking ability, and scores of classroom teaching, clinical teaching, support, and resources in the satisfaction scale, as well as significantly lower scores of negative problem orientation, avoidance style, and impulsive neglect style in the problem-solving questionnaire ( P<0.05). The observation group had significantly higher scores of classroom teaching, clinical teaching machine support, and resources than the control group. Conclusions:In the nursing practice teaching of otolaryngology and head and neck surgery, the application of E-learning digital platform combined with brainstorming teaching can effectively improve the performance of nursing interns and strengthen their problem-solving, self-learning, and critical thinking abilities, with a relatively high degree of satisfaction among nursing interns.

Objective:To obtain the normal reference range of hemodynamic ultrasound parameters after pediatric liver transplantation through big data query and statistical analysis, and compare their changes with age.Methods:The clinical liver transplantation ultrasound imaging database software V1.0 independently developed by Tianjin First Central Hospital was used to query the ultrasound hemodynamic parameters of 0-14 years old pediatric patients after parental liver transplantation from December 2012 to December 2022, including portal vein diameter (PVD) on the 1st day, 7th day, 1st month, 6th month, 1st year, 5th year, and 10th year after surgery. The changes in ultrasound blood flow parameters such as portal vein velocity (PVV), hepatic artery peak velocity (S), hepatic artery end diastolic velocity (D), and left hepatic vein velocity (LHVV) with postoperative time in different age groups were analyzed, the differences between age groups were compared, and statistical analysis was perform to obtain the 95% reference value range for each parameter.Results:A total of 731 pediatric patients aged 0-14 years who underwent parental liver transplantation were included in this study, with a total of 5 283 monitoring results. The ultrasound hemodynamic parameters PVV, hepatic artery S, D, and LHVV were highest at 7th day after surgery, and gradually showed a sustained and slightly decreasing trend with the prolongation of postoperative time. At the same time, there was no statistically significant difference in PVV, hepatic artery S, D, and LHVV among different age groups (all P>0.05). Conclusions:This study obtains the trend of ultrasound hemodynamic parameters after pediatric liver transplantation with prolonged follow-up time, and compared them among different age groups.After pediatric liver transplantation, there is no significant change in liver hemodynamic parameters with increasing age. Obtaining reference value ranges for various parameters in different age groups is of great clinical significance for early detection and diagnosis of postoperative vascular complications. Pediatric liver transplantation is more complex than adult liver transplantation, and in clinical monitoring, more attention should be paid to the dynamic changes of transplanted liver blood flow, combining with individual patient status, to provide imaging support for clinical diagnosis.

AIM: To compare the outcome of C3F8 versus silicone oil tamponade after pars plana vitrectomy(PPV)and inverted internal limiting membrane(ILM)for the treatment of highly myopic macular hole retinal detachment(MHRD).METHODS: Retrospective clinical study. Totally 45 patients(45 eyes)with highly myopic MHRD who visited our hospital between January 2019 and August 2022 were selected as the research subjects. The patients were divided into two groups according to different intraocular tamponade agents: C3F8(22 eyes)and silicone oil(23 eyes)groups. All patients underwent conventional three-incision PPV, ILM was tamped, a venous blood clot was placed on the tamped ILM, and 15% C3F8 and silicone oil were used as tamponade, respectively. The best corrected visual acuity(BCVA), multifocal electroretinogram(mfERG), the closure of the macular hole, retinal reattachment and the complications were observed.RESULTS: The macular hole closure rate was 77% in the C3F8 group and 83% in the silicone oil group, respectively(P>0.05), and retinal reattachment rates were 95% and 96%, respectively(P>0.05). The visual acuity of the two groups significantly improved, which was 0.99±0.34 and 1.22±0.37, respectively, and the C3F8 group was better than that of the silicone oil group(t=-2.156, P=0.037). After operation, the response density of the first ring of P1 wave in the first order kernel in mfERG was 114.27±26.37 nV/deg2 for the C3F8 group and 98.08±24.36 nV/deg2 for the silicone oil group, and the response density of the second ring of P1 wave was 80.45±14.94 nV/deg2 for the C3F8 group and 67.73±15.33 nV/deg2 for the silicone oil group, all of which were significantly higher compared to pre-operation [the response density of the first ring of P1 wave: 58.13±13.96 nV/deg2 for the C3F8 group and 55.30±10.48 nV/deg2 for the silicone oil group, the response density of the second ring of P1 wave: 51.18±8.19 nV/deg2 for the C3F8 group and 47.43±11.97 nV/deg2 for the silicone oil group](all P<0.05). It was found that the response density of the first ring of P1 wave was lower in the silicone oil group than in the C3F8 group(P<0.05). There was no statistically significant difference in the incidence of complications between the two groups(P>0.05).CONCLUSION: Silicone oil tamponade or C3F8 tamponade after PPV combined with ILM can both promote retinal reattachment and macular hole closure in patients with MHRD, and the C3F8 tamponade was superior to silicone oil in visual function recovery.

By analysing the similarity between defense qi and leukocytes in terms of function， site of action， and circadian rhythm， it is proposed that in traditional Chinese medicine （TCM）， the pathogenesis of leukopenia is defense qi deficiency. By analyzing the relevant discussions on the generation and transmission of defense qi in TCM classics， it is believed that the original qi in lower jiao （焦） is the source of defense qi， while the water and grain qi in middle jiao enriches defense qi， and the upper jiao transmits and distributes defense qi to the whole body. Therefore， when treating leukopenia after chemotherapy with TCM， Guilu Erxian Gelatin （龟鹿二仙胶） and Yougui Pill （右归丸） are often used to tonify the kidney and supplement essence， and moxibustion at Guanyuan （CV 4） and Qihai （CV 6） is usually accompanied to replenish the original qi in lower jiao and enrich the source of defense qi. Guipi Decoction （归脾汤）， Buzhong Yiqi Decoction （补中益气汤）， Shenling Baizhu Powder （参苓白术散）， and Sijunzi Decoction （四君子汤） are often suggested to strengthen spleen and replenish qi， in combination with moxibustion at Zhongwan （CV 12） and Zusanli （ST 36） to transport the spleen and stomach in the middle jiao to enrich the defense qi. Modified Guizhi Decoction （桂枝汤） to harmonize nutrient and defensive aspects is often used， and moxibustion at Dazhui （GV 14） and Feishu （BL 13） or scraping is added to dredge the striae and interstice in the upper jiao and promote transmission and dissemination of the defense qi. Considering the whole process of generation and distribution of defense qi， it is suggested to choose the most appropriate treatment modality flexibly， and combine internal treatment with external treatment， in order to provide ideas for the treatment of leukopenia in tumour patients.

Objective To investigate the influences of arctigenin(ATG)on ventricular remodeling and inflammatory reaction in chronic heart failure(CHF)rats,and to analyze its potential mecha-nism.Methods A total of 79 SD rats were randomly divided into sham operation group(n=12),and the remaining rats were inflicted with abdominal aortic coarctation to establish a rat CHF model.After modeling,60 CHF rats were randomly divided into CHF group,low and high dose ATG group(ATG-L and ATG-H groups,10 and 20 mg/kg,respectively),ATG+NC group[20 mg/kg ATG+100 μl high mobility group protein B1(HMGB1)negative control plasmid],and ATG+HMGB1 group(20 mg/kg ATG+100 pl HMGB1 overexpression plasmid),with 12 rats per group.After 4 weeks of corresponding intervention,heart function,levels of B-type brain na-triuretic peptide(BNP),N-terminal B-type brain natriuretic peptide precursor(NT-proBNP)andIL-6 and TNF-α,heart mass index(HMI)and left ventricular mass index(LVMI),pathological changes of myocardial tissue,cross-sectional area of myocardial cells and myocardial collagen vol-ume fraction(CVF)and protein expression of HMGB1/Toll-like receptor 4(TLR4)/NF-κB sig-naling pathway in left ventricular myocardial tissue were measured.Results Compared with the sham operation group,myocardial tissue HMGB1(0.42±0.05 vs 0.15±0.02)and TLR4(0.70± 0.09 vs 0.21±0.04)protein levels,and phosphorylated NF-κB p65(p-NF-κB p65)/NF-κB p65(0.73±0.09 vs 0.26±0.05)protein ratio were obviously increased in the CHF group,while the left ventricular ejection fraction(LVEF)and left ventricular short-axis fractional shortening(LVFS)were obviously decreased(P＜0.05).Myocardial tissue HMGB1(0.33±0.04、0.24±0.04 vs 0.42±0.05)and TLR4(0.56±0.06、0.41±0.05 vs 0.70±0.09)protein levels,and p-NF κB p65/NF-KB p65(0.61±0.08、0.49±0.06 vs 0.73±0.09)protein ratio were decreased,and the LVEF and LVFS were increased in the ATG-L group and ATG-H group than the CHF group(P＜0.05).Overexpression of HMGB1 obviously attenuated the inhibitory effects of ATG on HMGB1/TLR4/NF-κB signaling pathway,ventricular remodeling,and inflammatory reaction in CHF rats(P＜0.05).Conclusion ATG may suppress ventricular remodeling in CHF rats by in-hibiting HMGB1/TLR4/NF-κB signaling inflammatory pathway.

Objective To investigate the clinical characteristics,diagnosis,treatment,and prognosis of descending necrotizing mediastinitis(DNM)to provide a reference for the early diagnosis and timely treatment of DNM.Methods Data on DNM in China was electronically retrieved from the core databases and comprehensively reviewed from June 2012 to June 2023.The infection,pathogenic microorganisms,main symptoms,comorbidities and treatment methods of DNM were analyzed.Results The data of a total of 781 DNM patients,with an average age of(52.97±5.64)years,were retrieved,including 554 males and 227 females.Odontogenic source,tonsillitis,pharyngeal abscess,sialoadenitis,upper respiratory tract infection,foreign body injury,or iatrogenic traumatic procedures are common causes.Among these,odontogenic infection is the most common source.Streptococcus sp.(n=217)and Staphylococcus sp.(n=82)were most isolated,followed by Klebsiella pneumoniae and Pseudomonas aeruginosa(equally n=59).A total of 69.4％(542/781)of DNM patients recruited in this study were discovered to have various comorbidities,and more than one-third of these patients(n=185)had diabetes.Of the broad antibiotics,carbapenem was most frequently used as treatment,and vancomycin was the most frequently coadministered.The mediastinal drainage approach varies widely,and the optimal regimen is still unknown.Seventy-two patients were treated with video-assisted thoracoscopic/mediastinoscopic surgical drainage,22 patients were treated with percutaneous catheter drainage,30 underwent the transcervical approach,and 40 underwent thoracotomy.A total of 617 patients who were selected underwent the appropriate combined operation for surgical drainage according to the specific location of the infected focus.The overall mortality rate of all 781 DNM pa-tients included was 11.2％.Conclusion The most effective diagnosis and treatment of DNM is a high degree of clini-cal vigilance followed by prompt and adequate drainage with intensive care,including hemodynamic monitoring,nutri-tional support,computer tomographic scanning repeated as necessary,and combined use of systemic antibiotics.
