AIM: To investigate how angles kappa and alpha affect postoperative visual quality in patients with multifocal intraocular lens(mIOLs)implantation.METHODS: Retrospective cases series. A total of 46 patients(46 eyes)who underwent phacoemulsification were subsumed. The correlation between Preoperative angles kappa and alpha, wave-front aberrations and objective visual quality of cornea, internal, and total eye after surgery were analyzed using iTrace.RESULTS: The magnitude of angle kappa was negatively correlated with internal and total modulation transfer function(MTF)at 3 mm; the magnitude of angle kappa was positively correlated with astigmatism, trefoil, higher-order aberrations(HOAs)of both internal and total eye at 3 mm. The magnitude of angle alpha was negatively correlated with total MTF and total Strehl ratio at 3 mm. The magnitude of angle alpha was positively correlated with corneal coma at 5 mm, internal astigmatism at both 3 mm and 5 mm, and total spherical aberration(SA)at 3 mm. Multivariate linear regression analysis showed that, among candidate independent variables(kappa, alpha, astigmatism, SA, coma, trefoil, and HOAs), astigmatism is the only independent factor for altering corneal MTF at 3 mm and 5 mm; astigmatism and HOAs emerged as independent factors for altering internal MTF at 3 mm and 5 mm, and total MTF at 3 mm; astigmatism, SA and HOAs emerged as independent factors for altering total MTF at 5 mm.CONCLUSION: With greater preoperative angle kappa or angle alpha, patients who accept mIOL implantation tend to have larger internal astigmatism and HOAs, which resulting in poor visual quality, especially those with small pupil size.

OBJECTIVE:
To analyze the disease patterns and acupoint selection characteristics of acupuncture for epilepsy in ancient acupuncture texts, providing references and ideas for clinical acupuncture treatment of epilepsy.
METHODS:
Texts from the Chinese Medical Classics (5th edition) regarding acupuncture for epilepsy are reviewed. The frequency of acupoints, meridian association, distribution, specific points, corresponding epilepsy subtypes, and needling techniques are statistically analyzed. The Apriori algorithm is used for association rule analysis, and a complex network analysis is conducted for high-frequency acupoints and their corresponding subtypes and treatments.
RESULTS:
A total of 205 acupuncture prescriptions are identified. Ancient texts favored differentiation-based treatments for epilepsy, primarily classified into epilepsy, wind epilepsy, and five epilepsy. Commonly used acupoints include Baihui (GV20), Jiuwei (CV15), Shenmen (HT7), Shenting (GV24), and Xinshu (BL15), with a focus on the acupoints of the governor vessel, the bladder meridian, and the conception vessel. The acupoints on the head, face are combined with the acupoints on the limbs, with skillful use of the five-shu points and intersection acupoints. The most frequent combinations are Shenmen (HT7)-Baihui (GV20), Shenting (GV24)-Baihui (GV20), and Xinshu (BL15)-Shenmen (HT7). Visual network analysis revealed that Baihui (GV20)-Shenting (GV24), Baihui (GV20)-Shenmen (HT7), and Baihui (GV20)-Zhaohai (KI6) are core acupoint combinations. Treatment mainly involved moxibustion or combined acupuncture and moxibustion.
CONCLUSION
The acupoint selection for epilepsy treatment in ancient texts is precise, frequently using Baihui (GV20), Jiuwei (CV15), Shenmen (HT7), Shenting (GV24), and Xinshu (BL15), etc., with emphasis on calming epilepsy, awakening the spirit, relaxing tendons, and nourishing the heart.

As a crucial barrier to ensuring blood transfusion safety, blood virus inactivation technology plays an irreplaceable role in addressing the "window period" of detection, the threat of emerging pathogens, and the limitations of detection technologies. This article systematically reviews the current status and technical characteristics of mainstream blood virus inactivation technologies, and conducts an in-depth discussion on the application prospects and challenges of emerging technologies in this field. Among conventional technologies, the photochemical methods (including methylene blue, psoralen S-59/INTERCEPT system, and riboflavin/Mirasol system) have been widely used in clinical practice due to their broad-spectrum inactivation capacity. However, these methods are associated with functional impairment of blood components. The organic solvent/detergent (S/D) method performs excellently in inactivating viruses in plasma products yet is ineffective against non-lipid-enveloped viruses. Short-wave ultraviolet (UVC) direct irradiation technology eliminates the need for chemical additives, though its inactivation efficiency and compatibility with blood components requires optimization. The chemical modification method, while specifically designed for red blood cells, faces safety challenges such as potential immunogenicity. For emerging technologies, cold plasma technology shows great potential owing to its multi-target synergistic inactivation mechanism, though challenges regarding its biocompatibility and selectivity remain. Electrolyzed water technology has the advantages of low cost and operational simplicity, yet in-depth research is needed on the non-specific damage caused by active substances to blood components. Novel photodynamic therapy significantly improves inactivation efficiency by developing high-efficiency targeted photosensitizers and has broad prospects for combined applications with antibodies, nanomaterials, and other substances. Future development trends point to the "combination therapy" strategy, which leverages the synergy of multiple technologies to achieve the optimal balance between efficient virus inactivation and functional prservation of blood components. The development of such technologies needs to shift from "single-method" to "integrated approach", from "inactivation" to "viability preservation", and bridge the translation gap from "laboratory" to "global application". The ultimate goal is to establish a standardized, automated, and cost-controllable comprehensive blood safety assurance system.

Background Mercury, as a global heavy metal pollutant, poses a serious threat to human health. The toxicity of mercury depends on its chemical form. Distinguishing the forms of mercury in the environment is of great significance for mercury management and reducing human mercury exposure risks. Objective To establish a non-targeted metallomics method based on synchrotron radiation X-ray fluorescence (SRXRF) spectroscopy combined with machine learning to screen inorganic mercury (IHg) or methylmercury (MeHg) exposed rice plants. Methods Rice seeds were exposed to ultra-pure water (control group), 0.1 mg·L−1 IHg (IHg group) or MeHg (MeHg group) solutions, respectively. After germination, the seedlings were cultured for 21 d, and rice leaves were collected, dried, weighed, and pressed. The content of metallome in rice leaves was determined by SRXRF. Machine learning models including soft independent modeling cluster analysis (SIMCA), partial least squares discriminant analysis (PLS-DA), and logistic regression (LR) were used to classify the SRXRF full spectra of different groups and find the best model to distinguish rice exposed to IHg or MeHg. Besides, characteristic elements were selected as input parameters to optimize the model by improving computing speed and reducing model calculation. Results The SRXRF spectral intensities of the control group, IHg group, and MeHg group were different, indicating that exposure to IHg and MeHg can interfere the homeostasis of metallome in rice leaves. The results of principal component analysis (PCA) of SRXRF spectra showed that the control group could be well distinguished from the mercury exposed groups, but the IHg group and the MeHg group were mostly overlapped. The accuracy rates of the three models (PLS-DA, SIMCA, and LR) were higher than 98% for the training set, higher than 95% for the validation set, and higher than 94% for the cross-validation set. Besides, the accuracy of the LR model was higher than that of the PLS-DA model and the SIMCA model. Furthermore, the accuracy was 92.05% when using characteristic elements K, Ca, Mn, Fe, and Zn selected by LR to distinguish the IHg group and the MeHg group. Compared with the full spectra model, although the prediction accuracy of the characteristic spectral model decreased, the input parameters of the model decreased by 99.51%, and precision, recall, and F1 score were above 84.48%, indicating that the model could distinguish rice exposed to different mercury forms. Conclusion Non-targeted metallomics method based on SRXRF and machine learning can be applied for high-throughput screening of rice exposed to different forms of mercury and thus decrease the risks of people being exposed to mercury.

Pediatric malocclusion is common in dentistry.Some children with malocclusion combined with obstruc-tive sleep apnea-hypopnea syndrome(OSAHS)often fail to receive appropriate treatment due to a lack of multidisci-plinary diagnosis and treatment.It can cause abnormal ventilation during sleep,affecting the central nervous system and cardiovascular development and even causing neurological and behavioral problems.Pediatric OSAHS is caused by the narrowing of the upper respiratory tract,characterized by specific facial bone characteristics and neuromuscular factors and correlated with malocclusion.Due to its diverse clinical manifestations and etiology,the diagnosis and treatment of pediatric OSAHS require an interdisciplinary,personalized,and specialized approach.Questionnaires and physical ex-aminations can be used for preliminary screening.Moreover,children's stomatology and otorhinolaryngology examina-tions are the basis for disease diagnosis.Polysomnography(PSG)is currently the direct diagnostic method.There are var-ious treatment methods for OSAHS in children,and for OSAHS caused by adenoid tonsil hypertrophy,adenoidectomy and tonsillectomy are the main treatments.Othodontic treatment including mandibular advancement and rapid maxillary expansion et al is also effective for OSAHS in children with malocclusion.Currently,there is limited research on the cor-relation between childhood malocclusion and OSAHS,and multidisciplinary combination therapy may improve the cure rate,but there is a lack of sufficient evidence.In the future,the pathogenesis of OSAHS should be further elucidated,and research on multidisciplinary combination therapy should be promoted to achieve early intervention and treatment for potential and existing patients.

Objective:To clarify the genetic diagnosis of two children with ring chromosome 18 and explore their mechanisms and clinical phenotypes.Methods:Two patients treated at the Children′s Hospital of Henan Province respectively in June 2022 and March 2023 were selected as the study subjects. Genetic testing and diagnosis were carried out through copy number variation sequencing (CNV-seq), G-banded chromosomal karyotyping, and whole exome sequencing (WES). This study was approved by the Children′s Hospital of Henan Province (Ethics No. 2023-K-075).Results:Child 1 had mainly manifested developmental delay, white matter hypoplasia, type 1 diabetes mellitus, and micropenis. He was found to have a chromosomal karyotype of 46, XY, r(18)(p11.21q22.1)[40]/46, XY[7], and CNV-seq results showed that he has a 14.86 Mb deletion at 18p11.21p11.32 and a 14.02 Mb deletion at 18q22.1q23. Child 2 had peculiar facial features, delayed white matter myelination, developmental delay, atrial septal defect, severe sensorineural deafness, and congenital laryngeal stridor. He was found to have a chromosomal karyotype of 46, XY, r(18)(p11.2q23). CNV-seq result proved that he had a 14.86 Mb deletion at 18p11.21p11.32 and a 20.74 Mb deletion at 18q21.32q23. WES has failed to detect single nucleotide variants (SNVs) in either child, but revealed a large segmental deletion at chromosome 18 in both of them.Conclusion:Both children were diagnosed with ring chromosome 18 syndrome. The different size of the deletional fragments in the 18q region and mosaicism of ring chromosome 18 in child 1 may underlay the variation in their clinical phenotypes. The type 1 diabetes mellitus and micropenis noted in both children are novel features for ring chromosome 18 syndrome.
