AIM: To compare the visual quality in patients with low-to-moderate myopia after 0.05 D interval spherical lens optometry-guided small-incision lenticule extraction(SMILE)and conventional 0.25 D interval spherical lens optometry-guided SMILE.METHODS: Retrospective study. A total of 400 cases(400 eyes)with low-to-moderate myopia that underwent SMILE in the ophthalmology department of 989th Hospital of Joint Logistic Support Force from August 2021 to August 2023 were enrolled and the data from the right eyes were collected for analysis. According to the method of optometry test modality, they were divided into 0.05 D group and 0.25 D group, with 200 eyes in each group. The differences were compared between the two groups of patients in intraoperative corneal ablation thickness, uncorrected distance visual acuity(UDVA), high-order corneal aberrations(HOA), spherical aberrations, vertical coma, horizontal coma and trefoil aberrations before and at 1, 3 and 6 mo after surgery. Additionally, the percentage of eyes with residual spherical equivalent(SE)≤±0.25 D, postoperative visual symptoms and scores on the quality of visual(Qov)were compared between the two groups at 6 mo after surgery.RESULTS: The corneal ablation thickness in the 0.05 D group was 92.78±16.56 μm, which was slightly higher than that in the 0.25 D group(83.24±17.33 μm; P<0.001). The UDVA at each postoperative time point in the 0.05 D group was superior to that in the 0.25 D group(all P<0.001). The HOA, spherical aberration, horizontal coma and vertical coma in the two groups at 1, 3 and 6 mo after operation were higher than those before operation(all P<0.05). The spherical aberration in the 0.05 D group at each time point after surgery were higher than those in the 0.25 D group, and vertical coma were lower than those in the 0.25 D group(all P<0.05). At 6 mo postoperatively, the percentage of eyes with residual SE ≤±0.25 D in the 0.05 D group was 97.5%(195 eyes), which was higher than 87.5%(175 eyes)in the 0.25 D group(P<0.05). The most common adverse visual symptoms after SMILE in both groups were hazy vision and glare. The total Qov score in the 0.05 D group was 0.35(0.24, 0.55), which was lower than [0.62(0.32, 0.89)] in the 0.25 D group(P<0.05).CONCLUSION: Compared with conventional 0.25 D interval spherical lens optometry-guided SMILE, the 0.05 D interval spherical lens optometry-guided SMILE for the correction of low-to-moderate myopia has better predictability and can achieve better vision and visual quality.

Objective To investigate the clinical value of endoscopic ultrasound-guided fine needle aspiration(EUS-FNA)for esophageal stricture lesions that cannot be diagnosed by endoscopic general biopsy.Methods The clinical data of 6 patients with esophageal stricture lesions with EUS-FNA that cannot be clearly diagnosed by endoscopic general biopsy from January 2021 to Jun 2023 were retrospectively analyzed,and the accuracy of EUS-FNA was analyzed for esophageal stricture lesions that cannot be diagnosed by endoscopic general biopsy,while the results of surgery pathology or final follow-up results was taken as the diagnostic criteria.Results All the patients underwent EUS-FNA.The puncture clearly diagnosed 5 cases of malignancy and 1 case of chronic inflammation.Among them,5 patients underwent surgical operations,and the postoperative pathological findings were consistent with the puncture pathology.One patient was followed up for a long time and had repeated gastroscopy.There was no evidence of malignant tumor in the clinical manifestations and routine gastroscopic findings,so it was still considered to be an inflammatory change,which was consistent with the puncture pathological result.All patients had no complications,including abdominal pain,bleeding,perforation,and infection.Conclusion EUS-FNA is an effective and safe method for esophageal stricture lesions that cannot be diagnosed by endoscopic general biopsy and has high clinical application value.

AIM: To investigate the early visual quality after 0.05 D interval spherical lens optometry-guided small incision lenticule extraction(SMILE)for the correction of different degrees of myopia.METHODS: Retrospective study. A total of 200 cases(200 eyes)that underwent SMILE at the 989th Hospital of Joint Logistic Support Force from May to September 2023 were selected. The 0.05 D optometry was used to measure diopter. According to the preoperative spherical equivalent(SE), they were divided into low-to-moderate myopic group(>-6.0 D)and high myopic group(≤-6.0 D), with 100 eyes in each group. The total high-order corneal aberration(HOA), spherical aberration, coma and trefoil aberration were compared between the two groups preoperatively and at 6 mo postoperatively, and the quality of vision questionnaire was completed.RESULTS: The HOA, spherical aberration and vertical coma aberration in the two groups at 6 mo after operation were significantly higher than those before operation(all P<0.05). At 6 mo postoperatively, the HOA, spherical aberration and vertical coma aberration in the low-to-moderate myopic group were lower than those in the high myopic group(all P<0.05). The scores of the quality of vision questionnaire, near vision, night vision, night glare and visual fatigue in the low-to-moderate myopic group were all higher than those in the high myopic group(all P<0.05).CONCLUSION: Both low-to-moderate myopia and high myopia after the 0.05 D interval spherical lens optometry-guided SMILE had some visual symptoms, but great visual quality can be obtained after surgery.

BACKGROUND: As one of the most common endocrinal disorders for women at childbearing age, the diagnostic criteria of polycystic ovary syndrome (PCOS) have been defined differently among different international health organizations. Phenotypic heterogeneity of PCOS also brings about difficulties for its diagnosis and management assessment. Therefore, more efficient biomarkers representing the progression of PCOS are expected to be integrated into the monitoring of management process using metabolomic approaches. METHODS: In this prospective randomized controlled trial, 117 PCOS patients were enrolled from December 2016 to September 2017. Classical diagnostic parameters, blood glucose, and metabolome were measured in these patients before and at 2 months and 3 months of different medical interventions. The receiver operating characteristic (ROC) curves were built based on multivariate statistical analysis using data at baseline and 3 months' management, and combinational biomarkers with appreciable sensitivity and specificity were selected, which then validated with data collected at 2 months. RESULTS: A set of metabolites including glutamic acid, aspartic acid, 1-methylnicotinamide, acetylcarnitine, glycerophosphocholine, and oleamide were filtered out with high performance in representing the improvement through 3-month management of PCOS with high sensitivity and specificity in ROC analysis and validation with other two groups showed an appreciable area under the curve over 0.96. CONCLUSIONS: The six metabolites were representative of the remission of PCOS through medical intervention, making them a set of potential biomarkers for assessing the outcome of PCOS management.

OBJECTIVES: We assessed the role of social support in presenteeism by examining organizational commitment among Chinese healthcare workers. METHODS: One thousand four hundred thirty-four healthcare workers from 6 hospitals in 4 Chinese cities completed a questionnaire measuring presenteeism, social support, and organizational commitment. With organizational commitment as the mediator, regression analyses and structural equation modeling were used to test the model. RESULTS: Organizational commitment was directly inversely associated with presenteeism (β = - 0.42, p < 0.001). Coworker support was moderately but significantly inversely associated with presenteeism (β = - 0.15, p < 0.001), but the path from supervisor support to presenteeism was not significant (β = 0.05, p > 0.05). The correlation between supervisor support and coworker support was significant (β = 0.71, p <0.001). Supervisor support and coworker support were significantly positively associated with organizational commitment (β = 0.41, p < 0.001, and β = 0.14, p < 0.001, respectively). CONCLUSIONS Supervisor support was more important in promoting organizational commitment, while coworker support was more effective in reducing presenteeism. The mediating effect of organizational commitment was significant.
