AIM:To analyze differential proteins associated with the pathogenesis of dry eye(DE)using bioinformatics methods, in order to reveal their potential molecular mechanisms.METHODS: Articles published in PubMed and EMBASE databases from the inception of the database to August 31, 2023, that used proteomic methods to detect protein expression in clinical samples of dry eye were searched. Differential proteins were selected and further analyzed using the STRING database and Cytoscape software for hub gene screening and module analysis. Protein-protein interaction(PPI)analysis, gene ontology(GO)functional annotation, and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis were performed.RESULTS: A total of 21 articles were included, identifying 74 differentially expressed proteins. The most frequently occurring differential proteins were calgranulin A(SA1008), lipocalin-1(LCN1), lysozyme C(LYZ), mammaglobin-B(SCGB2A1), proline-rich protein 4(PRR4), transferrin(TF), and calgranulinB(S100A9). The top 10 hub genes were serum albumin(ALB), tumor necrosis factor(TNF), interleukin 6(IL6), IL1B, IL8, matrix metalloproteinase 9(MMP9), alpha-1-antitrypsin(SERPINA1), IL10, complement component 3(C3), and lactotransferrin(LTF). Module analysis suggested MMP9 and PRR4 as seed genes. KEGG analysis showed that differential proteins were mainly enriched in the IL17 signaling pathway(61.9%).CONCLUSION: The results reveal potential molecular targets and pathways for DE and confirm the association between the pathogenesis of DE and inflammation. Further in-depth research is needed to confirm the significance of these biomarkers in clinical practice.

Objective: To investigate the efficacy and safety of intelligent temperature-pressure-controlled flexible ureteroscopy combined with negative-pressure suction sheath lithotripsy in the treatment of upper urinary tract stones ≤2.5 cm. Methods: The clinical data of 225 patients with ≤2.5 cm upper urinary tract stones treated with this surgical method in our department during Aug. 2023 and Jul. 2024 were retrospectively analyzed. The patients were divided into the dual-control group (n=36) and conventional group (n=189) according to whether or not the intelligent temperature and pressure control device was used during operation. In the dual-control group，the intraoperative temperature and pressure in the renal pelvis were monitored and controlled in real time by the temperature and pressure sensors distributed at the end of the ureteral soft lens. The perioperative parameters，stone-removal rate，complication rate and renal function were compared between the two groups. Results: All operations were successfully completed in both groups. The postoperative procalcitonin (PCT) level [(22.75±5.85) ng/L vs. (29.08±6.60) ng/L，P=0.001]，difference in the white blood cell (WBC) level [(0.24±2.12)×10 cells/L vs. (1.19±2.17)×10 cells/L，P=0.016]，incidence of fever (2.8% vs. 16.9%，P=0.028) and overall complication rate (5.6% vs. 19.6%，P=0.042) were significantly lower in the dual-control group than in the conventional group，while the stone-clearance rate was slightly higher (88.9% vs. 82.5%，P=0.346)，with no significant difference. Conclusion: For upper urinary tract stones ≤2.5 cm，intelligent temperature-pressure-controlled ureteroscopy combined with negative-pressure suction sheath lithotripsy has a satisfactory stone-removal rate and a low rate of complications，which is worthy of clinical promotion.

Objective:To screen for preoperative frailty risk factors in elderly patients with spinal degenerative diseases and construct a risk prediction model.Methods:From September 2021 to August 2022, convenience sampling was used to select 324 elderly patients who underwent spinal surgery in the Department of Neurosurgery at Xuanwu Hospital, Capital Medical University as research subjects. The patients were surveyed using the General Information Questionnaire, Barthel Index, Nutritional Risk Screening 2002, Mini-mental State Examination, Geriatric Depression Scale-15, Generalized Anxiety Disorde-7, Athens Insomnia Scale, Charlson Comorbidity Index (CCI), and Modified Frailty Index. Binary Logistic regression analysis was used to explore the influencing factors of preoperative frailty in elderly patients with spinal degenerative diseases and establish a risk prediction model. Receiver Operating Characteristic (ROC) curve was used to assess the discriminative power of the model, and Hosmer-Lemeshow test was used to evaluate the goodness of fit of the model.Results:A total of 324 questionnaires were distributed, and 308 valid questionnaires were collected, with a valid response rate of 95.06% (308/324). Among 308 elderly patients with degenerative spinal diseases, 56 patients experienced preoperative frailty. Binary Logistic regression analysis showed that falls within one year, CCI, serum albumin, activities of daily living, and self-rated health status were the influencing factors for preoperative frailty in elderly patients with spinal degenerative diseases ( P<0.05). The area under the ROC curve of the prediction model was 0.851, with a sensitivity of 0.786 and a specificity of 0.778. Hosmer Lemeshow test indicated that the predictive model had a good fit (χ 2=3.764, P=0.709) . Conclusions:Falls within one year, CCI, serum albumin, activities of daily living, and self-rated health status are influencing factors for preoperative frailty in elderly patients with spinal degenerative diseases. The risk prediction model constructed can identify preoperative frailty early and has good predictive performance, which is worthy of clinical promotion.

Objective To evaluate the effectiveness of screening-intervention management program for high risk population of stroke in community.Methods Participants aged≥60 years old in Tairi Community,Fengxian District,Shanghai from May 2019 to July 2022 were selected as screening and intervention objects.The first round of stroke high-risk group screening was conducted in 2019 and 2020 in two years respectively,and the second round of stroke high-risk group screening(re-screening)was conducted in 2021 and 2022 respectively for the 2019 and 2020 screening groups,and the groups who had received stroke high-risk screening in both rounds of screening(overlapping groups)were selected as the observation objects of this study.The cerebrovascular function score was used to screen the high-risk individuals of stroke,75-100 was classified as non-high-risk,＜75 were classified as high risk,among which 50-74,25-49,0-24 were light,medium and severe risk,in turn.Baseline and follow-up data were collected for all screening groups,including systolic blood pressure,diastolic blood pressure,overweight or obesity,fasting blood glucose,glycated hemoglobin,triglyceride,total cholesterol,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,and blood uric acid.After the completion of screening,the test report interpretation and first diagnosis intervention were carried out on the screening site,and the screening results were recorded into the health examination file.The first intervention includes lifestyle intervention,risk factor intervention and therapeutic intervention for high-risk individuals.Lifestyle intervention and risk factor intervention were conducted through the distribution of popular science handbook for stroke prevention and individualized face-to-face guidance.Therapeutic intervention for high-risk individuals was guided by anti-platelet aggregation drug therapy,statin therapy,and further examination and treatment of cerebral vessels according to stroke risk assessment results and the incidence of related chronic diseases.Prior to the implementation of the project,the incidence of stroke in the community in 2018 was retrospectively investigated to compare annual changes in stroke screening-intervention.In the process of implementation of intervention management,stroke incidence monitoring of the whole community registered population was carried out,and the monitoring method was to conduct stroke incidence registration once a year,and cooperate with the disease control and community police station to obtain the community stroke incidence monitoring data and death registration information provided by the police station from 2018 to 2022.Results A total of 5 188 subjects who completed both the initial screening and the follow-up screening and met the inclusion and exclusion criteria were identified,of whom 2 269 were male and 2 923 were female.The age of participants ranged from 60 to 93 years at the time of the first round of screening,with a mean age of(68±6)years.The proportions of subjects in the age groups of 60-64,65-69,70-74,and≥75 years were 30.3％,34.7％,21.1％,and 14.0％,respectively.(1)After screening and intervention,the proportion of individuals with increased systolic blood pressure,diastolic blood pressure,fasting blood glucose,triglyceride,and low-density lipoprotein cholesterol all decreased(respectively 49.4％vs.57.3％,26.6％vs.28.7％,9.6％vs.10.9％,14.7％vs.17.0％,2.4％vs.3.3％;all P＜0.05),but the proportion of individuals with hyperuricemia increased(15.8％vs.13.1％,P＜0.01),with statistically significant differences.(2)Before the implementation of the screening-intervention program in 2018,the stroke incidence rate in the community was 332.1/100 000.The stroke incidence rates in the community during the period from 2019 to 2022 after the implementation of the screening-intervention program were 335.0/100 000,270.8/100 000,235.0/100 000,and 193.6/100 000,respectively.The incidence rates of ischemic stroke(x2trend=8.350,P=0.004)and stroke(x2trend=9.910,P=0.002)decreased during the period from 2019 to 2022,while the incidence rate of hemorrhagic stroke did not show a decreasing trend(x2trend=1.636,P=0.201).(3)The median baseline and follow-up cerebrovascular function scores for the 5 188 elderly individuals undergoing residual stroke risk screening were 82.50(52.50,98.75)and 88.5(59.00,100.00),respectively,with stroke risk rates of 39.8％and 35.6％before and after intervention,respectively.After intervention,the follow-up cerebrovascular function scores increased compared to the baseline,and the stroke risk rate decreased.The distribution of stroke risk levels before and after screening-intervention had statistically significant differences(P＜0.01).Conclusion Implementing a stroke high-risk population screening-intervention management program for the elderly in the community,combined with health examinations and family doctor team services,can significantly reduce the incidence,high-risk rate,and exposure level of risk factors for stroke in the community.

Objective:To explore the clinical effects of early rehabilitation treatment after repair surgery of skin and soft tissue defects accompanied by extensor tendon injury on the back of hand.Methods:This study was a retrospective non-randomized controlled study. From February 2015 to February 2023, 24 patients (15 males and 9 females, aged 12-55 years) with skin and soft tissue defects accompanied by extensor tendon injury on the back of hand, who met the inclusion criteria and were repaired with flap transplantation and tendon grafting or tendon anastomosis, were admitted to the First Affiliated Hospital of Air Force Medical University. According to different intervention time for postoperative rehabilitation treatment of patients, the patients were divided into conventional rehabilitation group and early rehabilitation group, with 12 cases in each group. Patients in early rehabilitation group received rehabilitation treatment immediately after surgery under the rehabilitation guidance of specialized rehabilitation physicians based on the characteristics of different postoperative periods. Patients in conventional rehabilitation group began rehabilitation treatment from the third week after surgery, and their rehabilitation treatment was the same as that of patients in early rehabilitation group from the second week after surgery. The patients in 2 groups were treated in the hospital until the sixth week after surgery. The occurrence of flap vascular crisis and tendon rupture were observed within 6 weeks after surgery. After 6 weeks of surgery, the manual muscle test was used to measure the pinching force between the index finger and thumb, lateral pinching force, three-point pinching force, and grip force of the affected hand; the total action motion method was used to evaluate the finger joint range of motion of the affected hand, and the excellent and good ratio was calculated; the Carroll upper extremity function test was used to score and rate the function of the affected hand.Results:Within 6 weeks after surgery, only 1 patient in conventional rehabilitation group suffered from venous crisis, and the flap survived after the second surgical exploration and anastomosis of blood vessels; there was no occurrence of tendon rupture in patients of 2 groups. After 6 weeks of surgery, there were no statistically significant differences in pinching force between the index finger and thumb, lateral pinching force, three-point pinching force, or grip force of the affected hand between the two groups of patients ( P>0.05); the excellent and good ratio of the finger joint range of motion of the affected hand of patients in early rehabilitation group was 11/12, which was higher than 7/12 in conventional rehabilitation group, but there was no statistically significant difference ( P>0.05); the affected hand function score of patients in early rehabilitation group was 90±6, which was significantly higher than 83±8 in conventional rehabilitation group ( t=2.41, P<0.05); the function rating of the affected hand of patients in early rehabilitation group was obviously better than that in conventional rehabilitation group ( Z=2.04, P<0.05). Conclusions:Early rehabilitation treatment for patients with skin and soft tissue defects accompanied by extensor tendon injury on the back of hand after repair surgery can improve hand function, but it would not increase surgery related complications, which is worthy of clinical promotion and application.

Objective To explore the clinical efficacy of arthroscopy combined with cubital tunnel expansion and plasty in the treatment of patients with elbow osteoarthritis and cubital tunnel syndrome.Methods A total of 101 patients with elbow osteoarthritis and cubital tunnel syndrome who were admitted to the Department of Orthopedics,Cangzhou Hospital of Integrated TCM-WM Hebei from September 2020 to August 2023 were selected as the research subjects.According to different surgical methods,the patients were divided into an observation group(n=51)and a control group(n=50).The surgical method in the observation group was arthroscopy combined with cubital tunnel expansion and plasty,and the surgical method in the control group was conventional cubital tunnel expansion and plasty.The operation time,intraoperative blood loss,length of hospital stay,and complications were observed and recorded for both groups.The mayo elbow performance score(MEPS)was used to assess elbow function,the activities of daily living(ADL)scale was used to evaluate daily living ability,and the visual analogue scale(VAS)was used to assess pain levels preoperatively and at 6 months postoperatively.Elbow range of motion,including pronation,supination,and flexion-extension,was measured using a goniometer.Nerve recovery was evaluated by measuring compound muscle action potential(CMAP)of the abductor digiti minimi,ulnar nerve conduction velocity(NCV),and motor evoked potential latency(MEPLP)using a Keypoint electromyography device.Results The operation time and length of hospital stay in the observation group were significantly shorter than those in the control group,and the intraoperative blood loss and complications were significantly less than those in the control group(P＜0.05).Before operation,there were no statistically significant differences in MEPS scores,ADL scores and VAS scores between the observation group and the control group(P＞0.05);6 months after operation,the MEPS scores and ADL scores of patients in the observation group were signifi-cantly higher than those in the control group,and the VAS scores were significantly lower than those in the control group(P＜0.05).Before operation,there were no statistically significant differences in pronation,supination and flexion-extension between the observation group and the control group(P＞0.05);6 months after operation,the pronation,supination and flexion-extension of patients in the two groups were significantly higher than those before operation(P＜0.05),but there were no statistically significant differences in pronation,supination and flexion-extension between the observation group and the control group(P＞0.05).Before operation,there were no statistically significant differences in CMAP,NCV and MEPLP between the observation group and the control group(P＞0.05);6 months after operation,the CMAP and NCV of patients in the observation group were significantly higher than those in the control group,and the MEPLP ratio was significantly lower than that in the control group(P＜0.05).Conclusion Conventional cubital tunnel expansion and plasty and arthroscopy combined with cubital tunnel expansion and plasty can improve the range of motion of the elbow in patients with elbow osteoar-thritis and cubital tunnel syndrome,but the latter features less damage and faster recovery,is better in improving elbow function and daily living ability,reducing pain,and adjusting electromyographic examination indicators,and has fewer complications.
