AIM: To compare the changes in corneal epithelial thickness(CET)after small incision lenticule extraction(SMILE)and femtosecond laser-assisted in situ keratomileusis(FS-LASIK).METHODS: A total of 187 patients(187 eyes)who underwent either SMILE or FS-LASIK at Urumqi Aier Eye Hospital between December 2022 and November 2023 were collected. The patients were divided into SMILE group and FS-LASIK group according to surgical methods. The CET of the patients was measured by optical coherence tomography(OCT)system before surgery and at 1 wk, 1, 3, and 6 mo postoperatively.RESULTS: Changes in corneal epithelial thickness(△CET)in the central, paracentral, and mid-peripheral regions were compared at 6 mo postoperatively. The SMILE group was characterized by the most significant thickening in the central area and the least thickening in the mid-peripheral area; while the FS-LASIK group was characterized by the most significant thickening in the paracentral area and the least thickening in the mid-peripheral region. At 1 wk, 1, 3, and 6 mo postoperatively, within the 0-7 mm corneal area, the △CET for both the SMILE and FS-LASIK groups was correlated with the preoperative spherical equivalent.CONCLUSION: Within 6 mo postoperatively, both SMILE and FS-LASIK showed a similar trend in epithelial thickening but with distinct characteristics. The change in corneal epithelial thickness for both procedures was positively correlated with the preoperative diopter.

Objective To develop a multivariate modeling and prediction approach using the data of influenza incidence, meteorological factors and PM2.5 variables in Hefei City, and to provide new insights into multivariate modeling and prediction methods. Methods PM2.5 data were transformed into fractal dimension data and, along with meteorological data, were incorporated into a ConvLSTM model. The performance of this model was compared with traditional ARIMAX and multivariate LSTM models. Results The ARIMAX model's testing set Mean Absolute Error (MAE) was 95.75, Root Mean Square Error (RMSE) was 176.72, and Index of Agreement (IA) was 0.396642. The multivariate LSTM model's testing set MAE was 22.18, RMSE was 43.06, and IA was 0.974611. For the fractal dimension-based ConvLSTM model, the testing set MAE was 17.37, RMSE was 32.25, and IA was 0.988149. Conclusion The fractal dimension effectively captures the complexity and self-similarity of PM2.5 concentration, providing the model with richer feature information. The fractal dimension-based ConvLSTM model significantly outperforms the traditional ARIMAX model and the multivariate LSTM model in prediction accuracy and can be used for predicting the number of influenza cases.

ObjectiveTo establish an educational intervention framework of electronic picture books for children with autism spectrum disorder (ASD) based on Creative Problem Solving (CPS) model, and observe the effect on social function. MethodsElectronic picture books were designed using CPS model, including the program of reading, interactive animation design and associated artistic activities. From March to June, 2023, 24 children with mild to moderate ASD were recruited from Maanshan Institute of Special Education, and randomly assigned into experimental group 1 (CPS-based cognitive picture book interventions, n = 8), experimental group 2 (CPS-based social picture book interventions, n = 8) and control group (Bloom's Taxonomy-based picture book interventions, n = 8), and received the interventions for four weeks, with a total of twelve times. They were assessed with speech, social, perceptual and health behavior using Autism Treatment Evaluation Checklist (ATEC) before and after treatment, and the differences were calculated. ResultsThere was a significant difference among the groups in the social and perceptual scores differences (F > 4.344, P < 0.05) and a near-significant difference in the health behaviour score difference (F = 2.921, P = 0.076). Post Hoc test showed that the differences in social scores were higher in both experimental groups than in the control group (P < 0.05); the difference in perceptual scores was significantly higher in experimental group 1 than in experimental group 2 (P < 0.01), but there was no significant difference with the control group (P > 0.05); the difference in health behavior scores was higher in experimental group 2 than in the control (P < 0.05), and the difference in experimental group 1 was slightly higher than in the control group (P = 0.072). ConclusionElectronic picture book interventions based on the CPS model may be more effective in enhancing social, perceptual and health behavior in children with ASD, but there may be differences among models.

The deficiency of fingers due to various reasons leads to a certain degree of loss of full or part hand functions. Physical and mental health of patients are seriously affected, and patients have varying degrees of reduced quality of life. Prosthesis fingers play an important role in completing the body shape and enhancing patients’ self-confidence and self-esteem. However, how to make prosthesis fingers perform coordinated movements and restore complete functions is a crucial problem that urgently needs to be solved. This paper reviews the methods of brain-computer interface controlled fine finger movements and elaborates on the origin, current situation, and advancements of the development of this technology, laying a foundation for subsequent research, with the expectation of helping patients solve the problems arising from the insufficiency or absence of finger functions.

Objective :
To investigate the protective effect of dimethyl fumarate(DMF) on maternal intrahepatic cholestasis(ICP) during pregnancy induced by di(2-ethylhexyl) phthalate(DEHP) exposure and its mechanism.
Methods :
Thirty-two 8-week-old female institute of cancer research(ICR) mice were randomly divided into 4 groups: Ctrl group, DEHP group, DMF group and DEHP+DMF group. DEHP and DEHP+DMF groups were treated with DEHP(200 mg/kg) by gavage every morning at 9:00 a.m. DMF and DEHP+DMF groups were treated with DMF(150 mg/kg) from day 13 to day 16 of gestation by gavage. After completion of gavage on day 16 of pregnancy, maternal blood, maternal liver, placenta, and amniotic fluid were collected from pregnant mice after a six-hour abrosia. The body weight of the mother rats and the body weight of the fetus rats were sorted and analyzed; the levels of total bile acid(TBA), alkaline phosphatase(ALP), aspartate aminotransferase/alanine aminotransferase(AST/ALT) in serum and TBA in liver, amniotic fluid and placenta were detected by biochemical analyzer; HE staining was used to observe the pathological changes of liver tissue; Quantitative reverse transcription PCR(RT-qPCR) was used to detect the expression levels of tumor necrosis factor-α(TNF-α), interleukin(IL)-6, IL-1, IL-18 and NOD-like receptor thermal protein domain associated protein 3(NLRP3) in the liver; Western blot was used to detect the expression of the nuclear factor KappaB(NF-κB) and NLRP3.
Results :
Compared with the control group, the body weight of the DEHP-treated dams and pups decreased(P<0.05); the levels of TBA, ALP, AST/ALT in the serum of dams and the levels of TBA in the liver, amniotic fluid, and placenta of dams increased(P<0.05); the histopathological results showed that liver tissue was damaged, bile ducts were deformed, and there was inflammatory cell infiltration around them; the levels of inflammation-related factors TNF-α, IL-6, IL-1, IL-18 and NLRP3 transcription in maternal liver increased(P<0.05); the expression of NF-κB and NLRP3 protein in maternal liver significantly increased( P<0. 05). Compared with the DEHP group,the body weight of both dams and fetuses significantly increased in DEHP + DMF group( P<0. 05); the levels of TBA,ALP,AST/ALT in the serum of dams and amniotic fluid of fetuses decreased( P<0. 05); the degree of liver lesions was improved; the transcription levels of inflammation-related factors TNF-α,IL-6,IL-1,IL-18 and NLRP3 in maternal liver decreased( P<0. 05); the expression of NF-κB and NLRP3 protein in maternal liver significantly decreased( P<0. 05).
Conclusion
DMF can effectively protect the DEHP exposure to lead to female ICP,and its mechanism may be through inhibiting the NF-κB/NLRP3 pathway and reducing liver inflammation.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

OBJECTIVE To evaluate the cost-effectiveness of finerenone combined with standard treatment regimen in the treatment of diabetic nephropathy (DN). METHODS From the perspective of healthcare service providers, a Markov model was established to simulate the dynamic changes of each stage in DN patients who received finerenone combined with the standard treatment regimen or the standard treatment regimen alone based on the phase Ⅲ clinical trial study of finerenone for DN. Markov model was used to perform the cost-effectiveness of long-term effects and the costs of the two therapies with a simulation cycle of 4 months, a simulation period of 15 years and an annual discount rate of 5%. At the same time, one-way sensitivity analysis and probability sensitivity analysis were performed, and the stability of the results was validated. RESULTS Accumulative cost of the standard treatment regimen was 579 329.54 yuan, and the accumulative utility was 8.052 4 quality-adjusted life year (QALYs); the accumulative cost of finerenone combined with the standard treatment regimen was 332 520.61 yuan, and the accumulative utility was 8.187 4 QALYs. Finerenone combined with the standard treatment regimen was more cost-effective. The results of one-way sensitivity analysis showed that dialysis status utility value, DN stage 3 utility value and DN stage 4 utility value had a great influence on the incremental cost-effectiveness ratio, but did not affect the robustness of the model. The results of probability sensitivity analysis showed that finerenone combined with the standard treatment regimen was more cost-effective with 100% probability. CONCLUSIONS For DN patients, finerenone combined with the standard treatment regimen is more cost-effective as an absolute advantage option.

Colorectal cancer (CRC) ranks as the second leading cause of cancer death worldwide. Although preventive colonoscopy screening has improved the survival rate of CRC patients in the past few years, there are still many patients diagnosed after symptoms appear. The surgery for CRC carries high risks and high recurrence, and ideal therapies remain to be developed. The Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway has become a focus of research due to its central role in cellular activities. As a classic oncogenic pathway, the JAK/STAT signaling pathway offers new possibilities for diagnosing and treating various malignancies, and it paves a new way for developing therapies for CRC. This pathway not only participates in basic cellular processes, such as proliferation, differentiation, and apoptosis but also plays a crucial role in immune responses and inflammation. Abnormal activation of the JAK/STAT signaling pathway is closely related to the occurrence and development of CRC. Studies have shown that the active components and compound prescriptions of traditional Chinese medicine (TCM) can inhibit the proliferation, invasion, migration, and angiogenesis while promoting the apoptosis and autophagy of CRC cells by interfering with the JAK/STAT signaling pathway. Furthermore, this pathway may also play a role in regulating the sensitivity of tumor cells to chemotherapy and radiotherapy, thus influencing the effectiveness of tumor treatment and impeding the progression of CRC. In recent years, research results have been updated rapidly, and previous literature summaries have failed to incorporate the latest findings, creating obstacles to accessing current literature. Therefore, this article supplements and summarizes information from the definition of the JAK/STAT pathway, association of this pathway with CRC, and TCM intervention of CRC. This review aims to provide references for future development of molecular biology regarding CRC and the research and development of new drugs.

ObjectiveTo investigate the effects of retention enema with Huangling Jiedu Xiezhuo granules(HJXG) on Nod-like receptor protein 3(NLRP3), intestinal flora, and short-term prognosis in patients with gout. MethodsA total of 60 patients with gout admitted to the hospital from January 2021 to December 2023 were selected and divided into a control group and an observation group according to the random number table method, with 30 cases in each group. The control group was treated with febuxostat, and the observation group was treated with retention enema with HJXG on the basis of the control group. After 14 days of continuous treatment, the clinical efficacy, traditional Chinese medicine (TCM) syndrome score, and visual analogue scale (VAS) pain index of the two groups were compared, and serum creatinine(SCr), blood urea nitrogen(BUN), uric acid(UA), cystatin C(CysC), β2- microglobulin(β2-MG), glomerular filtration rate test(GFR), creatinine clearance rate (Ccr), erythrocyte sedimentation rate(ESR), hypersensitive C-reactive protein,(hs-CRP), interleukin 6(IL-6), interleukin-1β(IL-1β), interleukin-18 (IL-18), NLRP3 inflammasome levels, and the number of intestinal flora were detected in the two groups. The prognosis of patients was followed up within 12 weeks. COX regression analysis was used to analyze the effect of short-term prognosis. ResultsAfter treatment, TCM syndrome scores and VAS pain index in both groups were reduced (P<0.05), and TCM syndrome scores in the observation group were significantly lower than those in the control group. After treatment, ESR, hs-CRP, IL-6, NLRP3, IL-18, and IL-1β were significantly decreased in both groups (P<0.01), and the levels of IL-6, ESR, NLRP3, and IL-18 were significantly improved in the observation group compared with the control group (P<0.05). BUN, SCr, UA, β2-MG, GFR indexes in both groups were significantly lower after treatment, Ccr indexes in both groups were significantly higher after treatment, and the levels of SCr, UA, CysC, and Ccr in the observation group were significantly better than those in the control group (P<0.05). After treatment, the intestinal flora in both groups was improved, and the observation group was significantly improved compared with the control group in terms of Lactobacillus, Proteus, Bacteroides, and Escherichia coli (P<0.05). COX regression analysis showed that retention enema with HJXG could reduce the risk of poor short-term prognosis in patients with gout compared with Western medicine alone. ConclusionThe retention enema with HJXG can improve the curative effect of patients with gout, improve the TCM syndromes, reduce inflammation, and enhance renal function, intestinal flora, and short-term prognosis.

ObjectiveIn order to provide a reference for the optimization of preparation process of stir-fried Glycyrrhizae Radix et Rhizoma(sf-GRR), the quality changes during the processing was studied. MethodsGlycyrrhizae Radix et Rhizoma was processed by stir-frying for 17 min, and samples were collected every 1 min during the processing. The appearance color of the samples was determined by visual analysis technology, the moisture and extract of the process samples were detected by the drying method and the hot extraction method of alcohol-soluble extract in the general rules of the 2020 edition of Chinese Pharmacopoeia(part Ⅳ), and the contents of liquiritin apioside, liquiritin, isoliquiritin apioside, isoliquiritin, licoricesaponin G2 and glycyrrhizic acid in the process samples were determined by high performance liquid chromatography(HPLC). Then principal component analysis(PCA), partial least squares-discriminant analysis(PLS-DA) and Spearman correlation analysis were used for clustering, discrimination and correlation analysis of the appearance color, moisture, extract and the contents of six internal components. Based on artificial neural network and random forest algorithm, the prediction model of processing degree of sf-GRR was established. On this basis, based on the five principles of quality marker(Q-Maker), explore the monitoring Q-Maker of sf-GRR. ResultsThe color of Glycyrrhizae Radix et Rhizoma deepened after stir-frying, and the appearance color of the sample changed from light yellow to dark yellow during processing. During the stir-frying process, the moisture content showed a decreasing trend with the extension of processing time, while the extract content showed an increasing trend with the extension of processing time. After stir-frying, the contents of liquiritin apioside, liquiritin and licoricesaponin G2 showed an overall decreasing trend, while the contents of isoliquiritin apioside and isoliquiritin increased, and the content of glycyrrhizic acid increased slightly. The correlation analysis showed that moisture was positively correlated with brightness(L*) and red/green value(a*), and negatively correlated with yellow/blue value(b*) and total color difference(E*ab). Isoliquiritin apioside and isoliquiritin had negative correlation with L* and a*, and positive correlation with b* and E*ab. The processing process of sf-GRR could be divided into two stages of the early stage(0-14 min) and the late stage(15-17 min), and could be divided into three stages of the early stage(0-6 min), the middle stage(7-14 min) and the late stage(15-17 min) by combining the moisture, extract, the contents of 6 components and color values. Based on artificial neural network analysis and random forest algorithm, isoliquiritin apioside, isoliquiritin, liquiritin and glycyrrhizic acid were selected as monitoring markers for sf-GRR. ConclusionBased on the analysis of the exterior-interior indicators of process samples of sf-GRR, this paper ultimately identifies four processing monitoring markers, which can provide a basis for optimizing the processing technology of sf-GRR.
