AIM: To investigate the efficacy of pars plana vitrectomy(PPV)with or without inner limiting membrane(ILM)peeling in refractory diabetic macular edema.METHODS:Totally 80 patients with refractory diabetic macular edema were retrospectively selected and assigned into groups according to the treatment method. Among them, 38 patients treated with PPV were included as group A, and 42 patients treated with PPV combined with ILM peeling were included as group B. The relevant data of patients in the two groups were collected, and the efficacy of the two groups was compared.RESULTS: At 1, 3, and 6 mo after surgery, the best corrected visual acuity(BCVA), central macular thickness(CMT), and severity of macular edema in the group B were all superior to those in the group A(all P<0.05). At 6 mo after the surgery, the incidence of complications in the group B was 12%, with no prominent difference compared to 18% of the group A(P>0.05).CONCLUSION:PPV combined with or without ILM peeling can improve visual function and relieve macular edema in patients with refractory diabetic macular edema. However, the combination of PPV and ILM peeling is superior to PPV alone in improving vision and relieving macular edema, and does not increase postoperative complications.

AIM: To predict diabetic retinopathy(DR)progression through macular layer thickness in diabetic patients detected by optical coherence tomography(OCT).METHODS: Retrospective study. The clinical data of 100 cases(200 eyes)of diabetic patients admitted to our hospital from January 2023 to September 2024 were collected. According to the international clinical DR classification, they were divided into the non-diabetic retinopathy(NDR)group with 32 cases(64 eyes), the non-proliferative diabetic retinopathy(NPDR)group with 38 cases(76 eyes), and the proliferative diabetic retinopathy(PDR)group with 30 cases(60 eyes). At the same time, 49 cases(98 eyes)of healthy controls whose age and gender were matched with those of the diabetic patients were collected as the normal group. All patients underwent OCT examination. The thickness changes of the retinal nerve fiber layer(RNFL), ganglion cell layer(GCL), inner plexiform layer(IPL), outer nuclear layer(ONL), photoreceptor cell layer and total retinal thickness(RT)in the subregions of the macular area were compared among the groups. The Eta coefficient was used to analyze the correlation between them and the severity of DR.RESULTS: The thickness of RNFL, GCL, IPL, ONL and photoreceptor cell layer in each sub-region and the average of macular area in the PDR group was significantly lower than that in the NDR and normal groups, while the average RT thickness was significantly higher than that in the NPDR, NDR and normal groups(all P<0.05). The thickness of RNFL(central area, upper inner and outer rings and lower inner and outer rings and average), GCL(upper inner and outer rings and lower inner and outer rings and average), IPL(upper inner ring), ONL(central, upper inner ring and lower inner ring)and photoreceptor cell layer(upper inner and outer rings and lower inner and outer rings and average)in macular area of the PDR group was significantly thicker than that in the NPDR group(all P<0.05). The thickness of RNFL, GCL, IPL, ONL and photoreceptor cell layer in each sub-region and the average of macular area in the NPDR group was significantly lower than that in the NDR and normal groups, while the average RT thickness was significantly thicker than that in the NDR and normal groups(all P<0.05). There was no statistically significant difference in the above indicators between the NDR group and the normal group(all P>0.05). The severity of DR was significantly correlated with the average thickness of RNFL, GCL, IPL, ONL, photoreceptor cell layer and RT in macular area(all P<0.001).CONCLUSION: OCT measurement of the thickness of RNFL, GCL, IPL, ONL, photoreceptor cell layer and RT in the macular area in the diabetic patients can evaluate the progression of DR.

Objectives To develop a multi-stage and multi-epitope vaccine, which consists of epitopes from the early secretory and latency-associated antigens of Mycobacterium tuberculosis (MTB). Methods The B-cell, cytotoxic T-lymphocyte (CTL) and helper T-lymphocyte (HTL) epitopes of 12 proteins were predicted using an immunoinformatics. The epitopes with antigenicity, without cytotoxicity and sensitization, were further screened to construct the multi-epitope vaccine. Furthermore, the proposed vaccine underwent physicochemical properties analysis and secondary structure prediction as well as 3D structure modeling, refinement and validation. Then the refined model was docked with TLR4. Finally, an immune simulation of the vaccine was carried out. Results The proposed vaccine, which consists of 12 B-cell, 11 CTL and 12 HTL epitopes, had a flexible and stable globular conformation as well as a thermostable and hydrophilic structure. A stable interaction of the vaccine with TLR4 was confirmed by molecular docking. The efficiency of the candidate vaccine to trigger effective cellular and humoral immune responses was assessed by immune simulation. Conclusion A multi-stage multi-epitope MTB vaccine construction strategy based on immunoinformatics is proposed, which is expected to prevent both active and latent MTB infection.

Objective:To evaluate the efficacy and safety of drospirenone and ethinylestradiol tablets (Ⅱ) in Chinese women with dysmenorrhea.Methods:This was a single-arm, open-label, interventional, multicenter, post-authorization safety/effectiveness study of drospirenone and ethinylestradiol tablets (Ⅱ) across 6 treatment cycles, a total of 526 patients were included in the dysmenorrhea subgroup. Visual analog scale (VAS) was used to assess the severity of menstrual pain. Secondary outcomes included unintended pregnancies, bleeding pattern, cycle control and safety.Results:After treated with drospirenone and ethinylestradiol tablets (Ⅱ), VAS of pain had decreased significantly compared with baselines [(49.5±23.7) vs (32.3±24.9) vs (20.7±19.4) vs (18.4±18.7) mm, P<0.01]. From the second cycle to the fifth cycle, the incidence of scheduled bleeding increased from 93.9% (450/479) to 96.4% (431/447). The duration of scheduled bleeding decreased from (5.7±2.7) to (5.4±1.8) days. The incidence of intermenstrual bleeding decreased from 9.0% (43/479) to 5.6% (25/447). 17.5% (92/526) patients reported adverse drug reactions, most frequently reported adverse events were breast pain, nausea, breast swelling, headache, and uterine bleeding. No death occurred during the study. Conclusion:Drospirenone and ethinylestradiol tablets (Ⅱ) is effective for the treatment of dysmenorrhea and has good safety.

Objective: To investigate the relationship between different physical activity pattern and trajectories of anxiety and depression scores in college students, and to provide evidence for exploring the influence of physical activity on the development of anxiety and depression. Methods: A total of 1 265 college students from grade 2017 in a comprehensive university were investigated longitudinally for five times through stratified cluster sampling. Physical Activity Rank Scale-3(PARS-3), Self-rating Anxiety Scale(SAS), and Self-rating Depression Scale(SDS) were used, and latent class linear mixed models(LCLMM) were used to identify the trajectories of anxiety and depression scores and multinomial Logistic regression models were used for exploring the relationship between small persistent status of physical activity among the five surveys and subgroups of trajectory and anxiety and depression scores. Results: A total of 940(74.3%) college students were indentified as low persistent physical activity group and 325(25.7%) of them were identified as moderatre-to-high persistent physical activity group. The trajectories of anxiety score were classified into three groups:low level group, high level-decreasing group, and high level group. The number and proportion of the three groups were 686(54.2%), 144(11.4%), 435(34.4%), respectively. The trajectories of depression score were classified into four groups:low level group, moderate level-decreasing group, moderate level-increasing group, and high level group. The number and proportion of the five groups were 604(47.8%), 170(13.4%), 177(14.0%), 314(24.8%), respectively. Compared to the students with moderate-to-high persistent physical activity, higher persistent physical activity was associated with higher risk of keeping anxiety score at a high level(OR=1.78), and higher odds of decreasing depression score at moderate level(OR=0.67), as well as with higher risk of increasing depression score from a moderate level(OR=1.79), and increase the risk of keeping depression score at a high level(OR=1.97)(P<0.05). Conclusion Low persistent physical activity of college students could increase the risk of anxiety and depression at a high level. Relevant departments in universities should encourage students to take part in physical activity,with special focus given to individuals with less amount of physical activity and take effective interventional measures to modify the development of anxiety and depression.
