AIM: To compare the efficacy of small-incision lenticule extraction(SMILE)and femtosecond assisted laser in situ keratomileusis(FS-LASIK)in the treatment of patients with myopia and astigmatism.METHODS: Retrospective analysis. A total of 100 cases(200 eyes)of patients with myopia and astigmatism treated in our hospital from December 2021 to December 2022 were collected. Among them, 50 cases(100 eyes)were divided into SMILE group and 50 cases(100 eyes)were divided into FS-LASIK group according to the treatment plans. The visual acuity and astigmatism, corneal morphology parameters, subjective visual quality scores, ocular surface indicators, postoperative complications, and quality of life were compared between the two groups before and after surgery.RESULTS: There was no significant difference in uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), astigmatism, corneal asphericity Q value, corneal surface regularity index(SRI), corneal thickness, and corneal curvature between the two groups before surgery and at 1 d, 1, and 6 mo after surgery(all P>0.05). At 1 and 6 mo after surgery, the subjective visual quality score, the quality of life score, Schirmer I test(SⅠt)and tear film break-up time(BUT)in the SMILE group were better than that in the FS-LASIK group(all P<0.05). The incidence of complications in the SMILE group was lower than that in the FS-LASIK group at 6 mo after surgery(P=0.005).CONCLUSION: Both SMILE and FS-LASIK have good clinical effects in the treatment of myopia with astigmatism, but the SMILE could alleviate ocular surface injury, reduce the risk of complications and improve the quality of lifes for patients.

Objective To evaluate the molluscicidal effect of spraying different formulations of niclosamide ethanolamine salt with drones against Oncomelania hupensis in ditches. Methods A semi-dry and semi-wet ditch with O. hupensis snails was selected in the second branch field of Jiangbei Farm, Jiangling County, Hubei Province in May 2023, and divided into 4 experimental areas, named groups A1, A2, B1 and B2. Environmental cleaning was performed in groups A1 and B2, and was not conducted in groups A2 or B2. Then, 50% wettable powder of niclosamide ethanolamine salt was sprayed with drones at an effective dose of 2 g/m² in groups A1 and A2, and 5% niclosamide ethanolamine salt granule was sprayed with drones at an effective dose of 2 g/m² in groups B1 and B2. O. hupensis snails were surveyed using the systematic sampling method 1, 3, 5, 7, 14 days after spraying, and the natural mortality and corrected mortality of O. hupensis snails were calculated. Results The occurrence of frames with living snails, mean density of living snails and natural mortality of snails were 97.50% (117/120), 6.30 snails/0.1 m² and 1.18% (9/765) in the test ditch before spraying, respectively. There were significant differences in the mortality of snails among four groups 1, 3, 5, 7 and 14 days after spraying niclosamide formulations with drones (χ² = 17.230, 51.707, 65.184, 204.050 and 34.435, all P values < 0.01). The overall mortality rates of snails were 94.51% (1 051/1 112), 79.44% (908/1 143), 96.54% (977/1 012) and 88.55% (1 021/1 153) in groups A1, A2, B1 and B2 (χ² = 207.773, P < 0.05), respectively. In addition, there was no significant difference in the overall snail mortality between groups A1 and B1 (P > 0.05), and the snail mortality in groups A1 and B1 were both statistically different from that in groups A2 and B2 (all P values < 0.05). Conclusion Both 50% wettlable powder of niclosamide ethanolamine salt and 5% niclosamide ethanolamine salt granule sprayed with drones are active against O. hupensis snails in ditches, and environmental cleaning may improve the molluscicidal effect.

Objective:To explore the potential correlation between cumulative pulse pressure (cumPP) level and metabolic syndrome (MetS), and to provide insights for MetS management.Methods:A total of 3 968 subjects who underwent health checkup were selected to form a research cohort, and the data were categorized into three groups based on the tertiles of cumPP levels. Cox proportional hazards regression model was employed to analyze the association between different cumPP levels and the incidence of new-onset MetS. Results:The risk of MetS increased with the increased tiers of the cumPP levels (2.5%, 4.3%, and 4.6%, Ptrend<0.001) during the median follow-up period of 2.16 years. Spearman rank correlation analysis showed that cumPP was positively correlated with waist circumference, systolic blood pressure, diastolic blood pressure and fasting plasma glucose (all P<0.05). The Cox proportional hazards regression adjusted model showed that the risk of MetS in Q2 and Q3 was higher than that in Q1 in the total population, and the same results were observed in males (all P<0.05), while there was no statistical significance in females. Model 3 of the total population adjusted for a variety of confounding factors displayed a higher risk of MetS in Q3 compared with that in Q1[1.654 (95% CI 1.272-2.151) ]. When stratified by sex, and the risk of MetS in Q3 was 1.665 times higher than that in Q1 (95% CI 1.245-2.227), while there was no statistically significant risk in female. According to the visual nomogram of independent risk factors screened by multivariate analysis based on Cox proportional hazards regression model, the incidence of MetS at 1 year, 2 years, and 3 years was 0.18%, 3.97% and 7.39%, respectively. In addition, the dose-response curve was plotted according to cumPP, suggesting that the risk of MetS gradually increased with the increase of cumPP in the total population. Subgroup analyses based on baseline systolic blood pressure levels showed that higher cumPP levels were associated with a higher risk of developing MetS, regardless of whether systolic blood pressure was abnormal. Conclusions:Elevated cumPP levels is significantly related to the incidence of new-onset MetS. Maintaining pulse pressure within an appropriate range over long term is crucial for the management of MetS.

To report the first case of cutaneous chronic active Epstein-Barr virus disease manifesting as persistent erythema multiforme in China. The 12-year-old female patient presented with recurrent erythema and blisters all over the body, accompanied by oral erosions for more than 5 months. Skin examination showed dark erythema scattered on the right upper eyelid and cheeks, as well as erosions and blisters arising in the dark erythema on the lower jaw; broad bean- to pigeon egg-sized blisters with clear fluids arising in erythema were scattered on the back, buttocks, and limbs, and some manifested as atypical targetoid lesions; there was a mung bean-sized erosion on the mucosa of the lower lip and the right buccal region each; the patient also presented with moon face and multiple striae atrophicae on the lower limbs. Histopathological examination of the skin lesions on the lower limb revealed basket-weave hyperkeratosis, epidermal necrosis, liquefaction degeneration of basal cells with subepidermal blister formation, and perivascular lymphocytic infiltration in the superficial dermis; direct immunofluorescence assay showed negative staining for IgG, IgM, IgA, and complement C3 among epidermal cells and at the basement membrane zone; enzyme-linked immunosorbent assay showed negative staining for serum antibodies against desmoglein 1/3 (Dsg1/3), BP180, and type Ⅶ collagen; immunohistochemical examination demonstrated partial positive staining for CD3, CD4, CD5, CD8, CD56, granzyme B, and Epstein-Barr virus-encoded RNA, positive staining for Ki67 (> 70%), but negative staining for CD20. The Epstein-Barr virus DNA level was measured to be 1.97 × 10 6 IU/ml in whole blood samples and 2.65 × 10 7 IU/ml in blister fluid samples. No mutation sites with functional significance were identified by whole-exome sequencing. Based on these findings, a diagnosis of cutaneous chronic active Epstein-Barr virus disease manifesting as persistent erythema multiforme was made. The patient was treated with methylprednisolone at a dose of 40 mg/d, intravenous drips of ganciclovir at 200 mg twice daily, etc., and discharged after improvement.

Purpose: The risk stratification of pediatric anaplastic large cell lymphoma (ALCL) has not been standardized. In this study, new risk factors were included to establish a new risk stratification system for ALCL, and its feasibility in clinical practice was explored. Materials and Methods: On the basis of the non-Hodgkin’s lymphoma Berlin–Frankfurt–Munster 95 (NHL-BFM-95) protocol, patients with minimal disseminated disease (MDD), high-risk tumor site (multiple bone, skin, liver, and lung involvement), and small cell/lymphohistiocytic (SC/LH) pathological subtype were enrolled in risk stratification. Patients were treated with a modified NHL-BFM-95 protocol combined with an anaplastic lymphoma kinase inhibitor or vinblastine (VBL). Results: A total of 136 patients were enrolled in this study. The median age was 8.8 years. The 3-year event-free survival (EFS) and overall survival of the entire cohort were 77.7% (95% confidence interval [CI], 69.0% to 83.9%) and 92.3% (95% CI, 86.1% to 95.8%), respectively. The 3-year EFS rates of low-risk group (R1), intermediate-risk group (R2), and high-risk group (R3) patients were 100%, 89.5% (95% CI, 76.5% to 95.5%), and 67.9% (95% CI, 55.4% to 77.6%), respectively. The prognosis of patients with MDD (+), stage IV cancer, SC/LH lymphoma, and high-risk sites was poor, and the 3-year EFS rates were 45.3% (95% CI, 68.6% to 19.0%), 65.7% (95% CI, 47.6% to 78.9%), 55.7% (95% CI, 26.2% to 77.5%), and 70.7% (95% CI, 48.6% to 84.6%), respectively. At the end of follow-up, one of the five patients who received maintenance therapy with VBL relapsed, and seven patients receiving anaplastic lymphoma kinase inhibitor maintenance therapy did not experience relapse. Conclusion This study has confirmed the poor prognostic of MDD (+), high-risk site and SC/LH, but patients with SC/LH lymphoma and MDD (+) at diagnosis still need to receive better treatment (ClinicalTrials.gov number, NCT03971305).

Objective:To explore the association between glutamyl transpeptidase (GGT) trajectories and new-onset metabolic syndrome to provide insights for the prevention and treatment of metabolic syndrome.Methods:A total of 3 209 subjects who met the inclusion criteria were enrolled in the study cohort of physical examination population. The GGT levels before follow-up were classified by R LCTMtools program into 3 GGT trajectory groups: low-stable group, medium-stable group and high-stable group. Cox proportional hazards regression model was used to analyze the correlation between different GGT trajectories and new-onset metabolic syndrome.Results:At the end of follow-up in 2020, the cumulative incidence of metabolic syndrome was 7.0%, and the incidence of metabolic syndrome in the low-stable group, medium-stable group and high-stable group were 3.9%, 11.4%, and 15.0%, respectively, showing a growth trend ( P<0.001). After adjusting for multiple confounding factors by Cox proportional hazards regression model, the risk of metabolic syndrome in medium-stable group and high-stable group increased in the total population. The hazard ratios (95% CI)for the high stable group in males and the medium-stable group in females were 1.67(1.07-2.60) and 3.29(1.14-9.53), respectively, compared with their respective low-stable group. Conclusion:Elevated longitudinal trajectory of GGT is a risk factor for new-onset metabolic syndrome, the risk of metabolic syndrome in the total population increased with the increase of long-term GGT level. It is recommended to maintain the long-term level of GGT at about 28 U/L in males and 14 U/L in females, respectively, to achieve the goal of early prevention of metabolic syndrome.

Primary prostate synovial sarcoma (PPSS) is rare in clinic. One patient was admitted to our hospital in May 2021. The patient was admitted to the hospital because of the physical examination. Preoperative pelvic enhanced MR, PETCT and preoperative puncture pathology suggested that pelvic soft tissue sarcoma was likely. Robot-assisted radical resection of pelvic tumor was performed, and the unilateral PPSS was diagnosed by postoperative pathology, immunohistochemistry and gene detection. Patients were treated with ifosfamide + adriamycin adjuvant chemotherapy one month after operation, and Proton therapy radiotherapy five months after operation. Follow-up for more than 2 years showed that the patients were generally in good condition, and no recurrence or metastasis was found in imaging.

Objective:To explore the relationship between the long-term dynamic change in alanine aminotransferase(ALT) level and metabolic associated fatty liver disease(MAFLD).Methods:A retrospective study was conducted on 6 864 subjects who underwent four consecutive physical examinations from 2017 to 2020 in a cohort study of physical examination population in Henan Province. The relation between ALT level and the shift of MAFLD risk was analyzed using a multi-state Markov model, and the bidirectional relationship between ALT level and MAFLD was explored using a random intercept cross-lagged model.Results:Multi-state Markov model after adjusting for confounding factors showed that the risk of MAFLD in ALT Q2, Q3, Q4 group was gradually higher than that in Q1 group; Compared with health status, non-alcoholic fatty liver disease and MAFLD status gradually increased the risk of ALT shifting from normal to abnormal. The random intercept cross-lagged model after adjusting for confounding factors showed that there was a significant positive bidirectional relationship between MAFLD and ALT level. The cross-lag effect of MAFLD→ALT level was 0.083(95% CI 0.078-0.087), and the cross-lag effect of ALT→MAFLD was 0.044(95% CI 0.039-0.050). And with the extension of time, the cross-lag effect gradually decreased. Conclusions:There is a significant bidirectional relationship between the long-term dynamic change of ALT level and MAFLD. The occurrence of MAFLD is more likely to increase the risk of elevated ALT level, emphasizing the need for enhanced early prevention and treatment of MAFLD.

Objective:To investigate the correlation between fasting plasma glucose (FPG) and new-onset carotid plaque through latent class trajectory models.Methods:A total of 953 observation objects came from the first affiliated hospital of Zhengzhou University in accordance with the inclusion criteria. According to the FPG values of the observed subjects during the annual physical examination from January 2017 to December 2019, the following four different FPG trajectories groups were determined by latent class trajectory modelling tools: the low-stable group, the medium stable group, the medium-high stable group, and the high stable group. Carotid plaque incidence in each group was followed up in 2020 to compare the differences of the cumulative incidences of the four groups. The Cox proportional risk regression model was used to analyze the correlation between different FPG trajectories and new-onset carotid plaque.Results:The incidence of carotid plaque increased with the increase of FPG trajectories by 11.13%, 19.70%, 23.44%, 23.81%, respectively, with significance ( P<0.001). After adjusting gender, age, BMI and other confounding factors with the cox proportional risk regression model, the risk of carotid plaque in the FPG medium stable group, medium and high stable group, high-stable group was still 1.895 (95% CI: 1.296-2.769), 2.273 (95% CI: 1.241-4.161), 2.527 (95% CI: 1.219-5.241) times of the low stable group (all P<0.05). Conclusion:The long-term high FPG levels are independent risk factors for the incidence of carotid plaque, and controlling FPG at a low level steadily can reduce the risk of carotid plaque.

Objective:To investigate the clinicopathological features, immunophenotype, diagnosis and differential diagnosis of mammary analogue secretary carcinoma of salivary gland (MASC) .Methods:From Jan. 2018 to Jan. 2021, 28 cases of salivary gland MASC were collected in Ningbo Diagnostic Pathology Center, and 10 cases of acinar cell carcinoma and 10 cases of adenoid cystic carcinoma were selected as controls. Immunohistochemical envision method was used to detect the expression of S-100,, DOG-1, CD117, SOX-10, Mammaglobin and Vimentin, and fluorescence in situ hybridization was used to detect the fusion gene of ETV6-NTRK3.Results:The S-100 protein, SOX-10 and Vimentin of MASC of salivary gland were diffusingly positive (28/28) , Mammaglobin (22/28) and CD117 (19/28) were partially positive, and DOG-1 was negative. ETV6-NTRK3 fusion transcription was successfully detected in 26 of 28 salivary gland MASC cases, of which 23 were positive and 3 were negative.Conclusions:Salivary gland MASC is a low-grade malignant epithelium tumor. Comprehensive detection of the expression levels of S-100 protein, SOX-10, DOG-1, Mammaglobin and CD117 is of great value for the diagnosis and differential diagnosis of MASC. FISH detection of ETV6-NTRK3 gene fusion has important reference value for definite diagnosis.
