AIM: To explore the efficacy of 0.05% cyclosporine A(CsA)eye drops for preventing dry eye after femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK).METHODS: In this prospective randomized controlled study, a total of 80 patients(80 eyes)who underwent FS-LASIK surgery at the Affiliated Hospital of Xuzhou Medical University from January 2025 to September 2025 were enrolled, and only the data from the right eye were included for analysis. Before surgery, these patients were randomly assigned in a 1:1 ratio using a computer-generated sequence to a control group or an experimental group. All patients received standard postoperative treatment starting from postoperative day 1, including 0.5% levofloxacin eye drops, 0.1% fluorometholone eye drops, and 0.1% sodium hyaluronate eye drops(four times daily for 3 mo). The experimental group additionally received 0.05% cyclosporine A eye drops in addition to the standard treatment. The following parameters were compared between the two groups preoperatively and at 1 and 3 mo postoperatively: ocular surface disease index(OSDI)score, numerical rating scale(NRS)for ocular symptoms, lipid layer thickness(LLT), meibomian gland dropout score, Schirmer's Ⅰ test(SⅠt), corneal fluorescein staining(CFS)score, non-invasive tear breakup time(NIBUT), and tear meniscus height(TMH). Confocal microscopy was employed to evaluate corneal nerve parameters, including corneal nerve fiber density(CNFD), corneal nerve branch density(CNBD), corneal nerve fiber length(CNFL), and corneal total branch density(CTBD), and to count Langerhans cell density(DCD). In addition, levels of interferon-gamma(IFN-γ), interleukin(IL)-1β, IL-6, IL-10, and matrix metalloproteinase-9(MMP-9)in the tear were measured using liquid chip technology.RESULTS: A total of 72 patients completed the final follow-up, including 37 patients(15 males, 22 females, mean age 24.05±4.00 y)in the experimental group, 35 patients(16 males, 19 females, mean age 23.77±3.71 y)in the control group. At 1 and 3 mo postoperatively, the experimental group showed significantly lower OSDI scores, NRS eye pain scores, and CFS scores(all P<0.01), and significantly higher NIBUT and TMH values, compared with the control group. Confocal microscopy revealed that DCD was significantly lower in the experimental group at 1 and 3 mo postoperatively, whereas CNFD, CNBD, CNFL, and CTBD were significantly higher at 3 mo postoperatively(all P<0.01). Analysis of tear inflammatory cytokines showed that the levels of IFN-γ, IL-1β, IL-6, and MMP-9 were significantly lower in the experimental group at 1 and 3 mo postoperatively compared with the control group(all P<0.01). Spearman correlation analysis revealed that OSDI and NRS scores were negatively correlated with NIBUT, corneal nerve parameters(CNFD, CNBD, CNFL, CTBD), and corneal sensitivity(all P<0.01), and positively correlated with CFS scores, tear inflammatory cytokines(IFN-γ, IL-10, IL-1β, IL-6, and MMP-9), and DCD(all P<0.01). Tear inflammatory cytokines were negatively correlated with corneal nerve parameters, NIBUT, and corneal sensitivity(all P<0.01), and positively correlated with CFS scores and DCD(all P<0.01). No significant correlations were observed among the remaining parameters(P>0.05).CONCLUSION: Prophylactic use of 0.05% cyclosporine A eye drops significantly improves dry eye symptoms and signs, suppresses ocular surface inflammation, and promotes the restoration of tear film stability in patients after FS-LASIK. Through its dual anti-inflammatory and neuroregenerative effects, cyclosporine A constitutes an effective adjuvant therapy for reestablishing ocular surface microenvironment homeostasis after refractive surgery.

Objective To analyze the clinical efficacy and safety of transurethral blue laser vaporization of prostate (BVP) in the treatment of benign prostatic hyperplasia (BPH), and to explore the feasibility of its promotion in primary hospitals. Methods Clinical data of 30 BPH patients undergoing BVP in our hospital during Sep. and Dec. 2024 were retrospectively analyzed. The preoperative prostate volume, decrease in hemoglobin level 2 hours after operation, operation time, postoperative bladder irrigation time, catheter indwelling time, and intra-/postoperative complications were recorded. The changes of international prostate symptom score (IPSS), quality of life (QoL) score, and maximum urinary flow rate (Qmax) were compared before operation and 6 months after operation. Results The mean prostate volume was (46.9±15.7) mL. BVP was successfully completed in 28 patients. The 2 unsuccessful cases (6.7%) converted to transurethral resection of the prostate (TURP) due to intraoperative bleeding. For the 28 successful cases, the median postoperative 2-hour hemoglobin decrease was 4 (2, 11) g/L, mean operation time (59.8±13.2) min, median postoperative bladder irrigation time 21 (18, 23) h, median postoperative catheter indwelling time 5 (5, 5) d, and median postoperative hospital stay 6 (5, 6) d. After catheter removal, urinary retention with infection occurred in 1 case (3.6%), and hemorrhage in 1 case (3.6%). No severe complications occurred during the perioperative period. At 6 months postoperatively, the 28 patients showed significant improvement compared to preoperative values in IPSS[11 (10, 11) vs. 22 (21, 26), P＜0.001], QoL score[2 (2, 3) vs. 5 (5, 6), P＜0.001], and Qmax[ (17.2±5.6) mL/s vs. (7.8±1.4) mL/s, P＜0.001]. Conclusion BVP is a safe and effective treatment for BPH, offering advantages such as minimal blood loss, short operation time, and few complications. It effectively improves patients' lower urinary tract symptoms and quality of life, and is recommended for promotion in primary hospitals.

OBJECTIVE To evaluate the influence of pharmaceutical quality control on the efficiency and outcomes of standardized medication therapy management （MTM） services for patients with coronary heart disease by using Economic， Clinical and Humanistic Outcomes （ECHO） model. METHODS This study collected case data of coronary heart disease patients who received MTM services during January-March 2023 （pre-quality control implementation group， n＝96） and June-August 2023 （post-quality control implementation group， n＝164）. Using propensity score matching analysis， 80 patients were selected from each group. The study subsequently compared the economic， clinical， and humanistic outcome indicators of pharmaceutical services between the two matched groups. RESULTS There were no statistically significant differences in baseline data between the two groups after matching （P＞0.05）. Compared with pre-quality control implementation group， the daily treatment cost （16.26 yuan vs. 24.40 yuan， P＜0.001）， cost-effectiveness ratio [23.12 yuan/quality-adjusted life year （QALY） vs. 32.32 yuan/QALY， P＜0.001]， and the incidence of general adverse drug reactions （2.50% vs. 10.00%， P＝0.049） of post-quality control implementation group were decreased significantly； the utility value of the EuroQol Five-Dimensional Questionnaire （0.74± 0.06 vs. 0.71±0.07， P＝0.003）， the reduction in the number of medication related problems （1.0 vs. 0.5， P＜0.001）， the medication adherence score （[ 6.32±0.48） points vs. （6.10±0.37） points， P＝0.001]， and the satisfaction score （[ 92.56±1.52） points vs. （91.95±1.56） points， P＝0.013] all showed significant improvements. Neither group experienced serious adverse drug reactions. There was no statistically significant difference in the incidence of new adverse reactions between the two groups （1.25% vs. 3.75%， P＝0.310）. CONCLUSIONS Pharmaceutical quality control can improve the quality of pharmaceutical care， and the ECHO model can quantitatively evaluate the effect of MTM services， making pharmaceutical care better priced and more adaptable to social needs， thus being worthy of promotion.

Objective To investigate the correlation between serum vitamin D level and heart failure based on cross-sectional analysis.Methods A total of 10,411 subjects included in the Na-tional Health and Nutrition Examination Survey(NHANES)database from 2013 to 2016 were select-ed as the study population.The serum 25-hydroxyvitamin D[25(OH)D]levels of all subjects were measured.According to the quartiles of serum vitamin D levels,the subjects were divided into four groups.Multivariate logistic regression analysis and restricted cubic spline regression analysis were employed to explore the correlation between serum vitamin D level and heart failure.Results There were statistically significant differences among the four groups in terms of age,gender,educational at-tainment,race,diabetes,hypertension,alcohol consumption,physical activity,and body mass index(P＜0.05).The incidence rates of heart failure in the four vitamin D quartile groups(from low to high)were 3.9％,2.7％,2.9％and 4.1％respectively,with a statistically significant difference(P＜0.05).The results of multivariate logistic regression analysis revealed that,compared with the subjects in the first quartile group of vitamin D,the odds ratios(OR)and 95％confidence intervals(CI)of heart failure in the second,third,and fourth quartile groups of vitamin D were 0.64(0.46 to 0.89),0.53(0.38 to 0.73)and 0.48(0.35 to 0.66)respectively,and the trend test showed P was less than 0.001.The results of restricted cubic spline regression analysis indicated that serum vitamin D level was non-linearly negatively correlated with heart failure(non-linear test P=0.005).At the initial stage,the risk of heart failure decreased with the increase in vitamin D level;when the vitamin D level reached a certain level,the risk of heart failure tended to stabilize or even increase slightly.Con-clusion Serum vitamin D level is non-linearly negatively correlated with the risk of heart failure.

Objective:To investigate the clinical experience and efficacy of unrelated umbilical cord blood hematopoietic stem cell transplantation (HSCT) for the treatment of congenital amegakaryocytic thrombocytopenia (CAMT).Methods:A case summary was conducted.The clinical data of 2 children with CAMT who were finally cured by unrelated umbilical cord blood HSCT in the Department of Pediatric Medicine, the First Affiliated Hospital of Zhengzhou University from March 2020 to August 2023 were retrospectively analyzed.Related studies were retrieved from databases CNKI, Wanfang and PubMed using search terms including " congenital amegakaryocytic thrombocytopenia" and " hematopoietic stem cell transplantation" from the inception to July 2024.The clinical characteristics, diagnosis and treatment processes, and prognosis of CAMT patients treated by HSCT were then summarized.Results:Both cases exhibited scattered skin haemorrhages throughout the body and carried 2 compound heterozygous mutations with pathogenicity in the MPL gene.Both patients were finally diagnosed with CAMT.Case 1 was a girl aged 3 at the time of transplantation, and case 2 was also a girl, who aged 5 at the time of transplantation.Both of them received unrelated umbilical cord blood HSCT and hematopoietic reconstruction was achieved.The time of neutrophil and platelet implantation was 21 and 40 days after transplantation in case 1, and 20 and 31 days in case 2, respectively.The chimerism rate of neutrophil implantation in both children was complete chimerism of donor cells.Implantation syndrome was detected in case 1 following transplantation.Case 2 suffered implantation syndrome, hypertensive encephalopathy, and cytomegalovirus infection following transplantation.Both children showed no graft-versus-host disease (GVHD).Both children had hematopoietic and immune reconstruction after transplantation and their primary diseases were cured.Cases 1 and 2 were followed up for more than 14 and 17 months, respectively.Both of them achieved disease-free survival during the follow up.Literature review of 26 cases with CAMT treated by HSCT, including the above-mentioned 2 cases was conducted, with an overall disease-free survival rate of 92.3%(24/26).Of 12 cases with CAMT typing, 10 were type Ⅰ and 2 were type Ⅱ.Of the 26 cases treated by HSCT, 17 had bone marrow HSCT, with an overall survival rate of 88.2%(15/17), and 2 had peripheral blood HSCT.Seven cases had umbilical cord blood HSCT (6 cases receiving unrelated umbilical cord blood HSCT and 1 case receiving related umbilical cord blood HSCT), with an overall survival rate of 100%.Unlike bone marrow and peripheral blood HSCT, unrelated umbilical cord blood HSCT did not result in 3-4 grade GVHD. Conclusions:Unrelated umbilical cord blood HSCT can achieve good therapeutic effects in CAMT patients when there is no suitable donor.Myeloablative pretreatment is conducive to CAMT patients.

Aim To investigate the effect of irisin on endothelial inflammation and atherosclerosis(As)in mice.Methods ApoE-/-mice were randomly divided into control group,As model group,and irisin group(treated with irisin based on the As model),with 10 mice in each group.The carotid tissues were stained using pathological techniques and immunofluorescence.Human aortic endothelial cells(HAEC)were cultured in vitro,treated with irisin,and stimulated with cholesterol crystal(CC).The protein levels of vascular cell adhesion molecule-1(VCAM-1)and intercellular cell adhesion molecule-1(ICAM-1)were then detected by Western blot.The expression of inflammatory cytokines interleukin-1β(IL-1β),interleukin-6(IL-6)and chemokine(C-C motif)ligand 2(CCL2)were detected by RT-qPCR.The ad-hesion of monocytes was assessed using cell adhesion assay.Results The carotid plaque area in the mice of As model group was significantly increased compared with that in control group(P＜0.05).In contrast,the plaque area was re-duced in the irisin group compared with the As model group(P＜0.05).Compared with the control group,the expression of VCAM-1,the number of CD68+macrophages,and the deposition of CC were increased in the carotid arteries of the As model group(P＜0.05),while irisin could reduce the expression of VCAM-1,the number of CD68+macrophages,and the deposition of CC(P＜0.05).At the in vitro level,the expression of VCAM-1 and ICAM-1,as well as the adhesion of monocytes in CC-stimulated HAEC,were increased(P＜0.05).However,irisin could inhibit the increased expression of VCAM-1 and ICAM-1(P＜0.05),as well as the adhesion of monocytes induced by CC(P＜0.05).The mRNA levels of IL-1β,IL-6 and CCL2 in HAEC of CC stimulated group were increased(P＜0.05),while irisin could inhibit the mRNA expressions of IL-1β,IL-6 and CCL2 induced by CC(P＜0.05).Conclusion Irisin can inhibit vascular inflamma-tion,thereby reducing the occurrence and progression of atherosclerosis.

Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

OBJECTIVES: To investigate the effect of orexin-A-mediated regulation of ionotropic glutamate receptors for promoting motor function recovery in rats with spinal cord injury (SCI). METHODS: Thirty-six newborn SD rats (aged 7-14 days) were randomized into 6 groups (n=6), including a normal control group, a sham-operated group, and 4 SCI groups with daily intrathecal injection of saline, DNQX, orexin-A, or orexin-A+DNQX for 3 consecutive days after PCI. Motor function of the rats were evaluated using blood-brain barrier (BBB) score and inclined plane test 1 day before and at 1, 3, and 7 days after SCI. For patch-clamp experiment, spinal cord slices from newborn rats in the control, sham-operated, SCI, and SCI+orexin groups were prepared, and ventral horn neurons were acutely isolated to determine the reversal potential and dynamic indicators of glutamate receptor-mediated currents under glutamate perfusion. RESULTS: At 3 and 7 days after SCI, the orexin-A-treated rats showed significantly higher BBB scores and grip tilt angles than those with other interventions. Compared with those treated with DNQX alone, the rats receiving the combined treatment with orexin and DNQX had significantly higher BBB scores and grip tilt angles on day 7 after PCI. In the patch-clamp experiment, the ventral horn neurons from SCI rat models exhibited obviously higher reversal potential and greater rise slope of glutamate current with shorter decay time than those from sham-operated and orexin-treated rats. CONCLUSIONS Orexin-A promotes motor function recovery in rats after SCI possibly by improving the function of the ionotropic glutamate receptors.
