AIM: To explore the accuracy and consistency of predicting postoperative vault in implantable collamer lens(ICL)surgery based on the NK and KS formulas of CASIA2 OCT.METHODS: Retrospective case study. The study included 85 patients(170 eyes)who underwent ICL implantation for the correction of moderate to high myopia at the Refractive Surgery Center of Lunan Eye Hospital from October 2022 to October 2023. Routine examinations including ultrasound biomicroscopy(UBM), corneal endothelium assessment, optometry, intraocular pressure measurement, fundus examination, and corneal topography were performed. Patients who met the indications for ICL surgery were selected, and the recommended lens size was determined based on parameters such as corneal diameter and anterior chamber depth using standard methods. A CASIA2 OCT examination was used to obtain the corresponding lens size and predicted vault using the NK and KS formulas. The differences and consistency between the predicted vault by NK and KS formulas and the actual vault at 1 wk, 1, 3, and 6 mo postoperatively were analyzed. Paired t-tests were used to analyze the differences between the predicted vault by NK and KS formulas and the actual vault at each postoperative time point. The consistency between the predicted vault by NK and KS formulas and the actual vault at each time point was assessed using Bland-Altman analysis. Multivariate linear regression was used to analyze the correlation between actual vault and various anterior segment parameters.RESULTS: The NK formula showed statistically significant differences between the predicted values and the actual vault at 1, 3, and 6 mo postoperatively(all P<0.05), but no statistically significant difference was observed compared to the actual vault at 1 wk postoperatively(P=0.340). The KS formula demonstrated a statistically significant difference between the predicted values and the actual vault measured at 6 mo postoperatively(P<0.05). The lens vector height and lens model were influcing facotrs for the vault at 6 mo postoperatively(all P<0.05). Both the NK formula and KS formula had the highest consistency between their predicted vault and the actual vault at 6 mo postoperatively.CONCLUSION: The NK and KS formulas of CASIA2 OCT showed the highest consistency between the predicted postoperative vault and the actual vault at 6 mo postoperatively. Both formulas can serve as effective references for ICL model selection.

Yuejuwan is a classic formula widely used by doctors to relieve liver and depression， with precise clinical efficacy in traditional Chinese medicine （TCM）. The authors used bibliometric methods to collect and collate 495 ancient data related to Yuejuwan， and 105 valid data were screened out， involving 68 ancient Chinese medical books. After systematic verification of the origin of the formula of Yuejuwan， the main treatment symptoms， the principle of the formula， the composition of the drug， the dosage， the preparation method， the decoction method， and other information， the results showed that Yuejuwan originated from the Danxi Xinfa （《丹溪心法》） of the Yuan Dynasty by ZHU Zhenheng， and it is composed of five medicines， namely Atractylodis Rhizoma， Cyperi Rhizom， Chuanxiong Rhizoma， Massa Medicata Fermentata， and Gardeniae Fructus. In terms of drug base， Atractylodis Rhizoma， Cyperi Rhizom， Chuanxiong Rhizoma， and Gardeniae Fructus are in line with the records in the 2020 edition of Chinese Pharmacopoeia， and Massa Medicata Fermentata is used. The preparation method is as follows： Massa Medicata Fermentata and Gardeniae Fructus are fried， and Cyperi Rhizoma is roasted in vinegar. Chuanxiong Rhizoma is used in the raw form， and Atractylodis Rhizoma is prepared with rice swill. The formula can regulate Qi and relieve depression and broaden the middle and remove fullness. It is clinically used for the treatment of six types of depression syndromes， chest and diaphragm plumpness， abdominal distension and leg acid， acid swallowing and vomiting， eating and drinking disharmony， toothache， mouth and tongue sores， and other diseases. The most used dosage of the formula in the ancient records through the ages is converted into the modern dosage， namely 3.05 g Atractylodis Rhizoma， 3.05 g Cyperi Rhizoma， 3.05 g Chuanxiong Rhizoma， 3.05 g Massa Medicata Fermentata， and 3.05 g Gardeniae Fructus， and the daily dosage is 15.25 g. The converted dosage is similar to that recorded in the 2020 edition of the Chinese Pharmacopoeia. The formula is in pill form， and medicine should be taken with lukewarm boiled water after the meal.

ObjectiveBased on functional near-infrared spectroscopy (fNIRS), we investigated the brain activity characteristics of gross motor tasks in children with autism spectrum disorder (ASD) and motor dysfunctions (MDs) to provide a theoretical basis for further understanding the mechanism of MDs in children with ASD and designing targeted intervention programs from a central perspective. MethodsAccording to the inclusion and exclusion criteria, 48 children with ASD accompanied by MDs were recruited into the ASD group and 40 children with typically developing (TD) into the TD group. The fNIRS device was used to collect the information of blood oxygen changes in the cortical motor-related brain regions during single-handed bag throwing and tiptoe walking, and the differences in brain activation and functional connectivity between the two groups of children were analyzed from the perspective of brain activation and functional connectivity. ResultsCompared to the TD group, in the object manipulative motor task (one-handed bag throwing), the ASD group showed significantly reduced activation in both left sensorimotor cortex (SMC) and right secondary visual cortex (V2) (P<0.05), whereas the right pre-motor and supplementary motor cortex (PMC&SMA) had significantly higher activation (P<0.01) and showed bilateral brain region activity; in terms of brain functional integration, there was a significant decrease in the strength of brain functional connectivity (P<0.05) and was mainly associated with dorsolateral prefrontal cortex (DLPFC) and V2. In the body stability motor task (tiptoe walking), the ASD group had significantly higher activation in motor-related brain regions such as the DLPFC, SMC, and PMC&SMA (P<0.05) and showed bilateral brain region activity; in terms of brain functional integration, the ASD group had lower strength of brain functional connectivity (P<0.05) and was mainly associated with PMC&SMA and V2. ConclusionChildren with ASD exhibit abnormal brain functional activity characteristics specific to different gross motor tasks in object manipulative and body stability, reflecting insufficient or excessive compensatory activation of local brain regions and impaired cross-regions integration, which may be a potential reason for the poorer gross motor performance of children with ASD, and meanwhile provides data support for further unraveling the mechanisms underlying the occurrence of MDs in the context of ASD and designing targeted intervention programs from a central perspective.

AIM: To evaluate the expression of tumor necrosis factor-α(TNF-α)in the iris and ciliary body of Wistar rats in the endotoxin-induced uveitis(EIU), and the effect of Xuebijing injection on its expression.METHODS:A total of 65 Wistar rats were randomly divided into three groups: Group A(normal saline, n=5), Group B(normal saline+endotoxin-injected, n=30), and Group C(Xuebijing+endotoxin-injected, n=30). The EIU model was induced in Wistar rats of the groups B and C by injecting LPS into the plantar surfaces of the hind feet, and normal saline(15 mL/kg)or Xuebijing(15 mL/kg)were intraperitoneally administered 30 min before LPS administration. The rats of the groups B and C were further divided into 6 subgroups after LPS injection, including 6, 12, 18, 24, 48, and 72 h subgroups, with 5 rats in each group. Furthermore, the intraocular inflammation of the rats was observed at each time above, the number of infiltrating cells in the aqueous humor was counted, and the pathological changes were observed in the iris and ciliary body of rats using hematoxylin and eosin(HE)staining. TNF-α expression in iris and ciliary tissue at different postoperative time points was evaluated using immunohistochemistry.RESULTS: Clinical observations indicated no signs of uveitis in the group A, signs of uveitis were observed in the group B. Both iris symptoms and damage were significantly reduced in the group C compared to the group B(P<0.01). Cell counts in the aqueous humor revealed no inflammatory cells in the group A, while the number of aqueous humor cells in the group C was significantly reduced compared to Group B(P<0.01). HE staining revealed no cellular infiltration in the group A. In the group B, some cellular infiltration was observed in the eyes at 6 h post-LPS exposure. The number of infiltrating cells increased over time, peaked at 24 h, and gradually declined thereafter. In the group C, cell infiltration was not obvious at 6 h, few at 24 h, and nearly disappeared by 48 h. Immunohistochemical staining showed higher TNF-α expression in the ciliary body and iris in the group B than in the group A(P<0.01). Compared to the group C, TNF-α expression in the group B was significantly upregulated following LPS injection(P<0.01).CONCLUSION:TNF-α expression was elevated in EIU rats, and there was a positive correlation between its mean optical density ratio and inflammation degree. Moreover, Xuebijing injection could alleviate inflammation response through the reduction of TNF-α levels.

Objective:To further investigate the safety and efficacy of Belimumab in the treatment of patients with systemic lupus erythematosus (SLE).Methods:All SLE patients treated with Belimumab from May 1, 2020 to February 1, 2022 in Peking Union Medical College Hospital were retrospectively collected and analyzed. The clinical manifestations, the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2000) score, and laboratory test such as levels of anti-dsDNA antibody, the medication before and after Belimumab treatment, adverse events were collected. Normally distributed data were tested using the t-test, otherwise the Wilcoxon paired signed rank test was used. Results:A total of 81 patients were enrolled in this study. The use of belimumab could significantly decrease the SLEDAI-2000 score [10.00(7.75, 12.00) vs. 4.00(3.75, 6.00), Z=-5.38, P<0.001], ESR of SLE patients [19.50(12.75, 32.25) mm/1 h vs. 14.00(7.75, 20.25) mm/1 h, Z=-3.71, P=0.003], anti-dsDNA titer detected by CLIFT [300.00 (117.00, 864.00) vs. 183.00(100.00, 471.00), Z=-4.15, P=0.001], meanwhile, increase the complement C3 [0.78 (0.62, 0.97)g/L vs. 0.69 (0.55, 0.84)g/L, Z=-4.68, P<0.001], and the complement C4 [0.12 (0.08, 0.19)g/L vs. 0.10 (0.05, 0.14)g/L, Z=-4.78, P<0.001]. We also observed that with the use of Belimumab, the dosage of Glucocorticoids decreased significantly, which were [10.00(7.50, 22.50) mg vs. 7.50(5.00, 10.00) mg, Z=-4.90, P<0.001]. In addition, the antibody of IgG, IgA and IgM decreased significantly. Only one patient stopped the administration of Belimumab due to the low level of immunoglobulin. Conclusion:Belimumab can alleviate disease activity of patients with SLE and help in safely tapering the daily dose of glucocorticoid with good safety.

Based on the long bud stage phenotype of a new Lonicera japonica Flos variety "Huajin 6", using "Huajin 6" and "Da Mao Hua" as materials, probing the mechanism of its phenotype formation. Detection of endogenous Jasmonic acid hormones (JAs) content; the genes related to jasmonic acid (JA) synthesis were identified by transcriptome analysis of Lonicera japonica; flower buds and flowers of "Huajin 6" and "Da Mao Hua" were collected at different periods, and the qRT-PCR (quantitative real-time PCR) technique was used to analyze the trend of the expression of synthesis-related enzyme genes in Lonicera japonica Flos during the bud stage. The study found that the content of JAs in "Huajin 6" Lonicera japonica Flos was significantly lower than that in "Da Mao Hua"; applying exogenous methyl-jasmonate (MeJA) to "Huajin 6" can restore its flowering phenotype, making it close to wild type Lonicera japonica Flos; there are significant differences in the expression of two allene oxide synthase genes (AOS), three lipoxygenase genes (LOX), and two allene oxide cyclase genes (AOC) in the flowers and buds of "Huajin 6" and "Da Mao Hua" at different periods. It is hypothesized that the low expression of JA synthesis-related enzyme genes in " Huajin 6" leads to the blockage of JA synthesis, which causes the formation of the long bud phenotype. This study laid a certain foundation for the genetic breeding of Lonicera japonica, provided a new idea for the improvement of Lonicera japonica varieties, and provided a reference for the study of JAs in plant flower organs.

Objective To analyze and compare the clinical manifestations and imaging features of children with secondary massive cerebral infarction after acute subdural hematoma(ASDH),and to evaluate its potential risk factors in order to provide evidence for the prevention,early diagnosis and early treatment of secondary massive cerebral infarction after ASDH.Methods The clinical data of children with ASDH aged 4～12 years were retrospectively studied.All the children received routine operation.The diagnosis of post-traumatic secondary massive cerebral infarction(MCI)was based on low-density areas on CT images and clinical signs.Clinical and radiographic findings related to patient outcomes were reviewed and statistically compared.Univariate and multifactor Cox regression analysis was used to evaluate the MCI after operation to obtain the factors affecting MCI.Results A total of 67 cases were included in the study,with 32 cases included in the MCI group and 35 cases included in the non-MCI group.There were significant differences between MCI and non-MCI groups in age(t=2.016,P= 0.048),body mass(t=2.389,P=0.020),multiple injuries(χ2=11.121,P=0.001),GCS(Z=-4.730,P＜0.001),hematoma volume(χ2=12.890,P=0.002),MLS(χ2=12.261,P=0.002)and perioperative shock(χ2= 14.417,P＜0.001).GCS(OR=0.322,P=0.002),perioperative shock(OR=10.992,P=0.007),multiple injury(OR= 6.547,P=0.046)and MLS score(OR= 46.974,P=0.025)were major risk factors for MCI in children with ASDH.Conclusion Perioperative shock,multiple injuries,low GCS and MLS greater than 10mm are risk factors for MCI.The incidence of MCI is significantly increased in children with multiple risk factors.

Objective: To analyze the characteristics of influenza virus detection in an influenza outbreak in schools, so as to provide a strategic basis for the treatment of influenza outbreaks in schools. Methods: A total of 1 702 samples were collected from 52 school influenza outbreaks reported in Linyi City in 2021-2022. The samples were divided into 3 types according to different symptoms during the management of the epidemic [group A:influenzalike illness (ILI) group; group B:mild illness group; group C:close contacts group]. Rt-PCR was used to detect influenza virus nucleic acid in the collected samples. The detection rate of influenza virus in the outbreaks was analyzed by χ2 test. Results: In total, 1 071 samples (62.93%) tested positive for influenza virus nucleic acid. Among them, 610 out of 726 samples (84.02%) were detected in group A, while 331 out of 634 samples (52.21%) were detected in group B. In group C, 130 out of 342 samples (38.01%) tested positive. The differences were statistically significant (χ2=260.71, P<0.01). In group A, males had a detection rate of 80.83% for influenza virus nucleic acid, compared to 91.36% for females. For group B, the rates were 53.31% for males and 50.87% for females. In group C, males had a rate of 30.72%, while females had a rate of 43.92%. Statistical significance for gender differences was observed only in groups A and C (χ2=12.67, 6.25, P<0.05). According to the days of onset, the detection rates of influenza virus nucleic acid among patients with onset 0-6 days were 56.30%, 74.49%, 89.35%, 86.23%, 69.67%, 62.75%, 34.33%, respectively, and the difference was statistically significant (χ2=128.27, P<0.01). Conclusions Mild cases and close contacts are likely key factors contributing to the prolonged emergence of new cases within classrooms during school influenza outbreaks. The progression of influenza symptoms is related to the risk of transmission.
