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 variation of peripheral blood monocyte subtypes in patients with rheumatoid arthritis(RA),to study variation of surface antigen expression intensity and plasma related cytokine content of monocytes of each subtype,and to discuss their clinical application value.Methods:Percentage of monocyte subtypes and mean fluorescence intensity(MFI)of monocyte surface markers(HLA-DR,CD64,CD11b)in peripheral blood of 38 patients with RA were detected by multi-parameter flow cytometry,and differences were statistically analyzed compared with 40 healthy controls(HV group).Plasma levels of five cyto-kines(IL-2,IL-6,IL-10,TNF-α and IFN-γ)were detected by flow fluorescence microsphere technology.Linear correlation analysis was performed to determine correlation between percentage of monocyte subtypes and MFI of their surface markers and expression of related cytokines in RA patients.Disease activity 28(DAS28)score was performed in RA patients to study its association with percent-age of monocyte subtypes and plasma cytokines.Results:Compared with control group,percentage of classical monocytes in RA pa-tients decreased significantly(P<0.05),while percentage of intermediate monocytes and non-classical monocytes increased signifi-cantly(P<0.01).HLA-DR expression(MFI)on monocyte subsets in RA group was significantly higher than HV group(P<0.05 or P<0.01).CD64 expression(MFI)on intermediate monocytes and non-classical monocytes in RA group was significantly higher than HV group(P<0.01 or P<0.001).CD11b expression(MFI)on intermediate monocytes in RA group was significantly higher than HV group(P<0.001).In RA group,percentage of intermediate monocytes was positively correlated with contents of IL-6,TNF-α and IFN-γ(P<0.01).HLA-DR expression(MFI)on intermediate monocytes was positively correlated with TNF-α content(P<0.05);CD64 expres-sion(MFI)on non-classical monocytes was positively correlated with contents of IL-2 and IL-10(P<0.05).In RA group,percentage of intermediate monocytes was positively correlated with DAS28(P<0.001);plasma IL-6 and TNF-α levels were positively correlated with DAS28(P<0.01).Conclusion:Characteristic expression of intermediate monocytes and their surface antigens are closely related to occurrence of RA,and related inflammation is triggered by secretion of related cytokines.Monocyte subtype detection can be a new experimental diagnostic index for RA.Dynamic monitoring of peripheral blood monocyte subtypes and plasma IL-6 and TNF-α in RA patients during treatment is helpful to guide clinical treatment of RA.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the effect of rare ginsenosides (RGS) on reproductive injury induced by cyclophosphamide (CP) in female rats.Methods:Twenty-four female rats were divided into four groups [normal control (NC), RGS, CP, and CP+RGS group] with 6 rats in each group. CP group (the model group) and CP+RGS group (the treatment group) were intraperitoneally injected with CP 30 mg/kg for 5 days for modeling, and CP+RGS group was given RGS intragastric intervention. General growth status of rats in each group was observed, the organ index was calculated, and the pathological changes of ovary, uterus, liver and kidney were observed by hematoxylin-eosin staining. Serum levels of estradiol, follicle stimulating hormone (FSH), luteinizing hormone (LH), pro-inflammatory factors interleukin (IL) 6, IL-1β, tumor necrosis factor-α were detected. The urine samples were collected after RGS treatment for metabonomics analysis. Metabolomic profiling based on ultra performance liquid chromatography (UPLC) coupled with mass spectrometry (MS) was used to analyze and determine the urine metabolites of rats in each group.Results:Compared with NC group, the ovary index of CP group [(0.054±0.015) %] was significantly decreased ( P<0.05), the uterus index [(0.293±0.036) %] and estradiol level [(62.9±6.4) pmol/L] were significantly decreased (all P<0.01), serum levels of FSH, LH, IL-6 and IL-1β [(20.4±1.0) U/L, (29.0±3.0) U/L, (185.4±28.6) ng/L, (72.9±2.0) ng/L, respectively] were significantly increased (all P<0.01). Compared with CP group, the ovary index in CP+RGS group [(0.075±0.010) %] was significantly increased ( P<0.05), serum estradiol level [(122.1±16.2) pmol/L] was significantly increased ( P<0.01), serum FSH, IL-1β and IL-6 levels [(16.7±1.0) U/L, (111.8±17.4) ng/L, (60.1±2.2) ng/L, respectively] were significantly decreased (all P<0.01). Metabonomics analysis results showed that, a total of 352 metabolites were detected in urine, of which 12 were found to be potential markers associated with reproductive injury according to the screening standard. After treatment with RGS, differential metabolites were improved in the direction of NC group. Pathway enrichment suggests that the therapeutic effect of RGS was related to multiple metabolic pathways, including purine metabolism and taurine and hypotaurine metabolism. Conclusion:RGS might reduce inflammation and thus ameliorate the damage caused by CP to the reproductive system of female rats by affecting purine metabolism and other pathways.

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.

Intelligent responsive drug delivery system opens up new avenues for realizing safer and more effective combination immunotherapy. Herein, a kind of tumor cascade-targeted responsive liposome (NLG919@Lip-pep1) is developed by conjugating polypeptide inhibitor of PD-1 signal pathway (AUNP-12), which is also a targeted peptide that conjugated with liposome carrier through matrix metalloproteinase-2 (MMP-2) cleavable peptide (GPLGVRGD). This targeted liposome is prepared through a mature preparation process, and indoleamine-2,3-dioxygenase (IDO) inhibitor NLG919 was encapsulated into it. Moreover, mediated by the enhanced permeability and retention effect (EPR effect) and AUNP-12, NLG919@Lip-pep1 first targets the cells that highly express PD-L1 in tumor tissues. At the same time, the over-expressed MMP-2 in the tumor site triggers the dissociation of AUNP-12, thus realizing the precise block of PD-1 signal pathway, and restoring the activity of T cells. The exposure of secondary targeting module II VRGDC-NLG919@Lip mediated tumor cells targeting, and further relieved the immunosuppressive microenvironment. Overall, this study offers a potentially appealing paradigm of a high efficiency, low toxicity, and simple intelligent responsive drug delivery system for targeted drug delivery in breast cancer, which can effectively rescue and activate the body's anti-tumor immune response and furthermore achieve effective treatment of metastatic breast cancer.
