AIM: To observe the clinical outcomes of Phorcides analytic engine-assisted topography-guided personalized laser assisted in situ keratomileusis(LASIK)for the treatment of myopia and astigmatism in virgin eyes with the refractive astigmatism significantly deviating from corneal topography.METHODS: Retrospective clinical study. A total of 32 cases(42 eyes)with myopia and astigmatism that received corneal topography-guided personalized LASIK in the Ophthalmology Refractive Surgery Center of the First Affiliated Hospital of Xi'an Jiaotong University from December 2019 to March 2021 were selected. The uncorrected distance visual acuity(UDVA), best corrected distance visual acuity(CDVA), refractive state and aberrations before and at 6 mo after surgery were recorded.RESULTS: There were 15 males and 17 females, with an age of 23.00(18.00, 29.25)years old; preoperative sphere was -5.75(-6.25, -4.00)D, and cylinder was -0.75(-1.38, -0.25)D. At 6 mo postoperatively, the UDVA exceeded the preoperative CDVA in 19 eyes(45%). The spherical equivalent(SEQ)of all eyes(100%)was -0.50 to +0.50 D at 6 mo postoperatively, and the postoperative SEQ of 23 eyes(55%)was -0.13 to +0.13 D. There were 33 eyes(79%)had a postoperative astigmatism ≤ 0.25 D, the target-induced astigmatism(TIA)was 0.94±0.96 D, and the surgically induced astigmatism(SIA)was 0.94±0.86 D, with no statistical significance between TIA and SIA(P>0.05). The astigmatism axial deviation ranged from -5° to +5° in 33 eyes(79%)at 6 mo postoperatively. Compared to pre-operation, the total higher-order aberrations and spherical aberrations within the central 6 mm diameter of the anterior corneal surface increased at 6 mo postoperatively(Z=-3.778, P<0.001; Z=-4.929, P<0.001); the postoperative coma aberrations had no change(Z=-1.763, P=0.078); the postoperative trefoil aberrations decreased(Z=-2.490, P=0.013). Compared to pre-operation, the Strehl ratio of the anterior corneal surface increased significantly at 6 mo after surgeries(t=-5.401, P=0.013).CONCLUSION: Using the Phorcides analytic engine to assist topography-guided personalized LASIK for the treatment of myopia and astigmatism in virgin eyes with the refractive astigmatism significantly deviating from topography-measured astigmatism can achieve good therapeutic effects. Postoperative UDVA exceeded preoperative CDVA in nearly half of the eyes, and the quality of postoperative corneal imaging was improved.

Objective: To analyze the association of eating dining locations and their association with nutritional status among Chinese children aged 6-17 years,so as to provide reference for guiding children s reasonable diet. Methods: Stratified random cluster sampling was used to select children aged 6 to 17 years from 28 cities and rural areas of 14 provinces in East, North, Central, South, Southwest, Northwest, Northeast of China, and a total of 52 535 children were included in the study from 2019 to 2021. Information including dining locations, demographic characteristics, dietary intakes and physical activity were collected through a questionnaire survey. Fasting body height and weight were measured in the morning. Unordered multiclass Logistic regression analysis was conducted to assess the relationship between dining locations and nutritional status in children. Results: Regarding children s dining locations, 66.3% ate breakfast at home,25.8% ate breakfast at school,7.9% ate breakfast outside (small dining tables, restaurants, stalls, etc.); 67.7% ate dinner at home,29.0% ate dinner at school,3.3% ate dinner outside; and 63.6% ate lunch at school,30.8% ate lunch at home,5.7% ate lunch outside. The prevalence rates of overweight/obesity and undernutrition were 28.6% and 9.3%, respectively. The adjusted multiclass Logistic regression analysis (controlling for age, region, parental education, household income, total energy intake, and moderate-to-vigorous physical activity) demonstrated that, compared to eating at home, school based breakfast and dinner consumption was associated with significantly lower overweight/obesity risks for both genders (boys: breakfast OR =0.70, 95% CI =0.65-0.75; dinner OR =0.80, 95% CI = 0.74- 0.86; girls: breakfast OR = 0.89 , 95% CI = 0.82-0.96; dinner OR =0.88, 95% CI =0.81-0.95), whereas eating lunch away from home significantly increased overweight/obesity risks (boys: OR =1.32, 95% CI =1.17-1.48; girls: OR =1.43, 95% CI =1.26- 1.62 ), with all associations being statistically significant ( P <0.05). After adjusting for confounding factors, boys who ate breakfast away from home showed a significantly reduced risk of undernutrition ( OR =0.80,95% CI =0.66-0.97), while those consuming lunch away from home had an increased risk ( OR =1.26, 95% CI =1.01-1.57) ( P <0.05). Conclusions The choice of dining locations for children is becoming more diverse, and a relatively high proportion of children eat meals outside the home and at school. Eating out have a higher risk of malnutrition for children. School feeding may be beneficial to children s physical health.

AIM: To investigate the potential inhibitory effect of pterostilbene on the endothelial-to-mesenchymal transition(EndMT)induced by high glucose conditions in human retinal microvascular endothelial cells(HRMECs).METHODS: The optimal concentration of pterostilbene for treating HRMECs was determined using the CCK-8 assay, with 12.5 and 25 μmol/L concentrations selected for subsequent experiments. Four experimental groups were established: control group, high glucose group, high glucose combined with 12.5 μmol/L pterostilbene treatment group, and high glucose combined with 25 μmol/L pterostilbene treatment group. The expression levels of HDAC7 and EndMT-associated markers were detected via Western blot analysis. Cell migration ability was assessed using Transwell migration assays and scratch wound healing tests, while vasculogenic capability was evaluated through tube formation assays.RESULTS: The CCK-8 assay revealed that pterostilbene at a concentration of 22.07 μmol/L inhibited 50% of cell viability in HRMECs. Western blot analysis demonstrated that compared with the control group, the expression levels of HDAC7, ZEB1, Vimentin, and Snail were significantly upregulated in HRMECs cultured in high glucose(all P<0.01), while the expressions of VE-cadherin and CD31 were significantly reduced(all P<0.01). Compared to the high glucose group, the treatment with 12.5 and 25 μmol/L pterostilbene significantly reduced the expression of HDAC7, ZEB1, Vimentin, and Snail under high glucose conditions(all P<0.01). Notably, 25 μmol/L pterostilbene enhanced the expression of VE-cadherin and CD31(all P<0.01). Scratch wound healing tests revealed that HRMECs treated with high glucose exhibited a significantly increased cell migration rate compared to the control group(P<0.05), while the application of 25 μmol/L pterostilbene significantly suppressed HRMECs migration under high glucose conditions(P<0.01). Transwell migration assays demonstrated that the cell migration rate in the high glucose group was significantly higher than that in the control group(P<0.01), with cell migration rate markedly reduced following treatment with both of 12.5 and 25 μmol/L pterostilbene(all P<0.01). The tube formation assay revealed that the ability of HRMECs to form tubular structures was significantly enhanced under high glucose conditions(P<0.01), and both 12.5 and 25 μmol/L of pterostilbene effectively inhibited this effect(all P<0.01).CONCLUSION: Pterostilbene can inhibit HDAC7 expression, suppress EndMT-mediated migration of HRMECs, and impair tube formation under high-glucose conditions.

ObjectiveA qualitative analysis method was established for the composition of Astragali Radix（AR） before and after rice stir-frying. On the basis of systematic characterization of the chemical compositions in AR and stir-fried AR with rice（ARR）， the structures of their major compounds were deduced and identified， and the differential compositions between them were analyzed. MethodsUltra performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was used to detect the samples of AR and ARR in positive and negative ion modes， respectively. The compounds were analyzed and identified through self-constructed databases， literature， and reference standards， etc. And the data were analyzed by chemometrics， in order to screen for the differential components between AR and ARR. ResultsA total of 123 compounds were identified in AR and ARR， including 41 flavonoids， 19 terpenoids， 26 organic acids， 8 amino acids， 5 nucleotides， 5 carbohydrates and 19 other compounds. Among them， there were 95 common components in both， 18 unique components in AR， and 10 unique components in ARR. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） results both showed that there were significant differences in the chemical constituents of AR before and after rice stir-frying， and a total of 26 constituents with differences in the content were screened out， including L-canavanine， L-pyroglutamic acid， L-phenylalanine， cis-caffeic acid， and malonylastragaloside Ⅰ. Among them， 19 constituents of ARR were down-regulated and 7 constituents were up-regulated by comparing with AR. ConclusionThis study clarifies that the chemical composition of AR and ARR is mainly composed of flavonoids， terpenoids， and organic acids， and analyzes the components with significant differences in content between the two in combination with chemometrics， and the differential components are dominated by amino acids， organic acids and terpenoids， which can provide reference for the subsequent quality control and material basis research.

AIM: To assess the consistency of the new anterior segment analyzer, MS-39, the Sirius and Pentacam in measuring corneal white-to-white(WTW)and central anterior chamber depth(ACD), and to compare their differences in guiding implantable collamer lens(ICL)size selection.METHODS: Retrospective case study. A total of 210 consecutive patients(420 eyes)who treated at the Ophthalmology Refractive Surgery Center of the First Affiliated Hospital of Xi'an Jiaotong University between September 2019 and September 2020 were enrolled. Three anterior segment analysis systems, MS-39, Sirius, and Pentacam, were utilized to assess the WTW and ACD, with comparative analysis of the results. The sizing of the ICL V4c was simulated using the method recommended by the STAAR company. Data correlation and consistency were evaluated.RESULTS: The WTW measurement results obtained from MS-39, Sirius, and Pentacam were 11.39±0.35, 11.42±0.36, and 11.46±0.35 mm, respectively. Notably, the WTW measurement value from MS-39 was significantly lower than that from Pentacam(P=0.002), while no statistically significant differences were observed between MS-39 and Sirius, or between Sirius and Pentacam(all P>0.05). The WTW measurements from the three devices exhibited a strong positive correlation, with correlation coefficients(r)of 0.942 between MS-39 and Sirius, 0.925 between MS-39 and Pentacam, and 0.882 between Sirius and Pentacam(all P<0.0001). The ACD measurements values from the MS-39, Sirius and Pentacam were 3.28±0.22, 3.28±0.24, and 3.21±0.23 mm, respectively. While, no statistically significant difference was found between MS-39 and Sirius(P>0.05), both measurements were significantly higher than that of Pentacam(both P<0.0001). The ACD measurements also demonstrated a strong positive correlation, with r values of 0.959 between MS-39 and Sirius, 0.947 between MS-39 and Pentacam, and 0.932 between Sirius and Pentacam(all P<0.0001). In terms of ICL size selection based on the measurements from the three devices, the 12.6 mm size was the most frequently selected, while the 13.7 mm size was the least common, the distribution of size selections across the devices was similar.CONCLUSION: MS-39 demonstrated strong positive correlation with both Sirius and Pentacam for WTW and ACD measurements, indicating that the results can be considered clinically interchangeable. Furthermore, the outcomes derived from MS-39 for ICL size selection were closely aligned with those from Sirius and Pentacam, suggesting its clinical feasibility.

Objective:To explore the dynamic temporal variability of brain functional networks in individuals with internet gaming disorder(IGD)using dynamic functional connectivity density(dFCD).Methods:From January 2019 to December 2021, resting-state functional magnetic resonance imaging data were recruited from 55 patients with IGD and demographically matched 50 healthy controls.Data analysis was performed by IBM SPSS 21.0 software. The functional connectivity density(FCD) combined with sliding window analysis was employed to calculate the temporal variability of global functional connectivity.FCD in whole brain was further devided into ipsilateral and cotralateral parts.The temporal variability of dFCD was further quantified utilizing the standard deviations of whole brain, intra-, and inter-hemispheric FCD. Finally, Pearson correlation analysis was performed between dFCD variance in differential brain regions and clinical behaviors.Results:The inter-hemispheric dFCD in the left posterior cingulate cortex(-0.16±0.24) and the left precuneus(-0.08±0.23) in patients with IGD were lower that those in healthy controls(0.002±0.260, 0.12±0.36)( t=-3.502, -4.160, both P<0.05).And the intra-hemispheric dFCD in the left calcarine, the left precuneus, and the left posterior cingulate cortex in patients with IGD were lower that those in healthy controls( t=-3.809, -4.360, -3.561, all P<0.05).Moreover, abnormal global dFCD variability of the calcarine and ipsilateral dFCD variability of the PCC negatively correlated with the severity of IGD( r=-0.380, -0.413, both P<0.05). Conclusion:Patients with IGD show intra-and inter-hemispheric dFCD differences in the visual attention network and default mode network, which may respond to the underlying neurobiological basis for the presence of cognitive dysfunction and impaired concentration.

Objective:To analyze clinical and histopathological diagnoses of patients with solid tumors localized on the perianal and external genitalia regions, aiming to help clinicians correctly identify benign and malignant tumors.Methods:A retrospective analysis was conducted on clinical, histopathological, and dermoscopic features, diagnosis and treatment of 389 patients diagnosed with solid tumors localized in the perianal and external genitalia regions in the Department of Dermatology, Peking University Third Hospital from January 2016 to May 2023.Results:Among the 389 patients with solid tumors in perianal and external genitalia regions, 123 were males and 266 were females, with the age being 8 - 89 (41.86 ± 16.62) years. Based on the histological classification of skin tumors, melanocytic tumors were the most common type (33.16% [129/389]), followed by other tumors (21.59%, 84/389), keratinocytic tumors (21.08%, 82/389), soft tissue and neural tumors (13.62%, 53/389), and appendageal tumors (10.54%, 41/389). There were 83.03% (323/389) of benign tumors and 16.97% (66/389) of malignant tumors. Melanocytic nevus was the most common benign tumor, mostly involving the labia majora of females and mons pubis of males. Among the malignant tumors, squamous cell carcinoma was relatively common in females (40%, 10/25), while extramammary Paget′s disease was relatively common in males (39.02%, 16/41). The initial misdiagnosis rate of Bowenoid papulosis was the highest (11/11), followed by squamous cell carcinoma (78.26%, 18/23) and basal cell carcinoma (40%, 4/10) ; there was no significant difference in the initial misdiagnosis rate between different gender groups or different age groups (both P>0.5). A total of 367 patients underwent surgical excision under local anesthesia and all showed a good prognosis; the remaining 22 with malignant tumors were treated with photodynamic therapy, extended resection, free flap transfer, etc., and experienced no recurrence during the follow-up of 3 months to more than 3 years. Conclusions:Solid tumors in the perianal and external genitalia regions were polymorphous, melanocytic tumors, keratinocytic tumors and other tumors accounted for a large proportion, while malignant tumors were relatively rare, and some were easily misdiagnosed. Most of the tumors in the regions had a good prognosis, without recurrence after the surgical resection.

Objective:To evaluate the efficacy and safety of chidamide combined with curcumin in the treatment of cutaneous T-cell lymphoma (CTCL) .Methods:Human CTCL cell lines HH and HuT-78 were cultured in vitro and treated with gradient concentrations of chidamide (0.4, 0.8, 1.6, 3.2, and 6.4 μmol/L) and curcumin (1.25, 2.5, 5, 10, and 20 μmol/L) alone or in combination, and the combination index (CI) of chidamide and curcumin for HH and HuT-78 cells was evaluated. Cultured HH/HuT-78 cells were divided into chidamide group (treated with 0.4 μmol/L chidamide), curcumin group (treated with 10 μmol/L curcumin), combination group (treated with 0.4 μmol/L chidamide + 10 μmol/L curcumin), and solvent control group (treated with dimethyl sulfoxide) ; after 48-hour treatment, the MTS assay was performed to evaluate the cell viability, flow cytometry to detect cell apoptosis and analyze cell cycle, and real-time quantitative PCR (RT-PCR) and Western blot analysis were conducted to determine the mRNA and protein expression of apoptosis-related genes nuclear factor (NF) -κB p65, B-cell lymphoma 2 (Bcl-2), and caspase-3, respectively. A tumor-bearing mouse model was established with HH cells in immunodeficient mice. These tumor-bearing mice were randomly divided into 4 groups: chidamide group (gavaged with 10 mg/kg chidamide), curcumin group (gavaged with 100 mg/kg curcumin), combination group, and solvent control group. The treatment was administered daily for 12 days, and body weight and tumor size were measured. On day 13, these mice were sacrificed, and tumor tissues were collected. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining was performed to detect apoptosis of tumor cells, and RT-PCR and Western blot analysis were conducted to determine the expression of apoptosis-related genes and proteins. Differences among multiple groups were analyzed using one-way analysis of variance, and multiple comparisons were performed using least significant difference- t test. Results:The CI values of chidamide (0.4 - 6.4 μmol/L) combined with curcumin (1.25 - 20 μmol/L) were all < 1, indicating a synergistic effect. After 48-hour treatment, the proliferation rates of HH and HuT-78 cells were significantly lower in the combination groups than in the chidamide groups and curcumin groups (all P < 0.05) ; HH and HuT-78 cells both showed significantly increased apoptosis rates in the combination groups compared with the chidamide groups, curcumin groups and control groups (HH cells: 70.47% ± 7.87% vs. 31.95% ± 9.43%, 37.23% ± 10.74%, 11.76% ± 5.65%, all P < 0.001; HuT-78 cells: 28.31% ± 1.70% vs. 21.29% ± 3.61%, 18.74% ± 1.82%, 3.18% ± 1.00%, all P < 0.001) ; in both HH and HuT-78 cells, the combination groups exhibited significantly increased caspase-3 mRNA expression and cleaved protein levels (all P < 0.05), but significantly decreased mRNA and protein expression of NF-κB p65 and Bcl-2 compared with the control groups, chidamide groups, and curcumin groups (all P < 0.05). On day 13 in the in vivo experiment, the tumor volume was significantly lower in the combination group (107.00 ± 43.10 mm 3) than in the control group (1 833.00 ± 281.20 mm 3), chidamide group (453.30 ± 91.71 mm 3), and curcumin group (548.50 ± 90.72 mm 3, all P < 0.05) ; the apoptosis level of tumor cells detected by TUNEL staining was significantly higher in the combination group than in the chidamide group, curcumin group, and control group (all P < 0.05) ; compared with the chidamide group, curcumin group, and control group, the combination group showed significantly increased expression of caspase-3 mRNA and cleaved caspase-3 protein (all P < 0.05), but significantly decreased mRNA and protein expression of NF-κB p65 and Bcl-2 (all P < 0.05). During the treatment period, there was no significant difference in the body weight of mice among the 4 groups ( P < 0.05) ; after sacrifice of the mice, no abnormalities were found in histopathological manifestations of their resected visceral tissues, blood routine test results, or liver and kidney function indicators. Conclusion:The combination of chidamide and curcumin had a synergistic antitumor effect on CTCL, which may be related to the inhibition of cell proliferation and induction of tumor cell apoptosis.

Objective:To analyze the clinical features and immunotherapy responsiveness of patients with myelin oligodendrocyte glycoprotein immunoglobulin G-antibody associated disease (MOGAD) with epilepsy, and display the risk factors of epilepsy in MOGAD.Methods:Eighty-nine patients with MOGAD diagnosed at the First Affiliated Hospital of Zhengzhou University between October 2019 and May 2023 were enrolled and classified into 2 groups upon MOGAD with ( n=29) or without epilepsy ( n=60). The Expanded Disability Status Scale (EDSS) and Clinical Assessment Scale for Autoimmune Encephalitis (CASE) were used for evaluation of severity, and EDSS or CASE scores on the 30th day after first-line immunotherapy initiation lower than that on admission were defined as well treatment responsiveness. The differences of general data, clinical manifestations, cerebrospinal fluid (CSF) and peripheral blood biochemical examination results, and immunotherapy reactivity between the 2 groups were thoroughly explicated. In addition, the risk factors of epilepsy in MOGAD were analyzed by univariate and multivariate Logistic regression analysis. Results:Compared with patients with MOGAD without epilepsy, patients with MOGAD with epilepsy were characterized by lower age of onset [24.5(10.3, 34.0) years vs 11.0(6.5, 20.0) years, Z=-2.348, P=0.019], higher percentage of male patients [43.3%(26/60) vs 75.9%(22/29), χ 2=8.326, P=0.004], higher virus infection rate [28.3%(17/60) vs 51.7%(15/29), χ 2=4.645, P=0.031], higher incidence of prodromal symptoms [11.7%(7/60) vs 34.5%(10/29), χ 2=6.586, P=0.010], higher blood-brain barrier breakdown rate [35.0%(21/60) vs 58.6%(17/29), χ 2=4.458, P=0.035], higher percentage of CSF albumin level>450 mg/L [48.3%(29/60) vs 75.9%(22/29), χ 2=6.056, P=0.014] and higher creatine kinase level [45.50(28.50, 69.75) U/L vs 57.50(41.75, 97.25) U/L, Z=-2.349, P=0.019]; more epilepsy [0(0) vs 29/29 (100.0%), χ 2=89.000, P<0.001] and disturbance of consciousness [0(0) vs 6/29(20.7%), χ 2=10.224, P=0.001] as clinical manifestations, and more cerebral cortex lesions [30/60(50.0%) vs 25/29(86.2%), χ 2=10.856, P=0.001] on magnetic resonance imaging. Nevertheless, the patients with MOGAD without epilepsy were featured with more visual impairment [23/60(38.3%) vs 3/29(10.3%), χ 2=7.406, P=0.007], limb weakness [18/60(30.0%) vs 1/29(3.4%), χ 2=8.209, P=0.004], sensory disturbance [15/60(25.0%) vs 0(0), Fisher exact probability test, P=0.002] and more cervical cord lesions [22/60(36.7%) vs 4/29(13.8%), χ 2=4.946, P=0.026] on magnetic resonance imaging. Immunotherapy responsiveness was relatively poor in the MOGAD with epilepsy group [EDSS score lower than that on admission: 15/29(51.7%) vs 46/60(76.7%), χ 2=5.641, P=0.018; CASE score lower than that on admission: 16/29(55.2%) vs 47/60(78.3%), χ 2=5.072, P=0.024] compared with the MOGAD without epilepsy group. Male was the independent risk factor of epilepsy in MOGAD ( OR=7.078, 95% CI 1.709-29.326, P=0.007). Conclusions:Compared with patients with MOGAD without epilepsy, patients with MOGAD with epilepsy reported more male patients, lower age of onset and higher incidence of prodromal symptoms, blood-brain barrier dysfunction rate, virus infection rate, CSF albumin level and creatine kinase level; clinical phenotypes were mainly meningoencephalitis and more cerebral cortex lesions were shown on magnetic resonance imaging. MOGAD with epilepsy was closely related to poor immunotherapy responsiveness, and gender was found to be the independent risk factor for epilepsy in MOGAD.
