There are difficulties in the treatment of Alzheimer's disease (AD) in medical community. Since the surgery of cervical deep lymphatic vessel/lymphatic node-vein anastomosis (LVA/LnVA) has made clinical improvement in patients with AD, it offers a surgical option to treat AD. Especially improvements in cognitive impairment. However the mechanism in treatment of AD is not yet made clear. This article preliminarily explores the mechanism in improvement of some symptoms in patients with AD through cervical deep LVA/LnVA on the basis of morphological characteristics of the cribriform plate-cervical lymphatic pathway.

Objective: To analyze the association of participation in non-sports extracurricular tutoring classes with the prevalence of screening myopia, axial length (AL) and axial length to corneal radius ratio (AL/CR) among primary school students, so as to provide evidences for formulating myopia prevention and control policies. Methods: In December 2024, combination of convenience and cluster sampling method was used to select 2 273 students from two primary schools in Hefei City, Anhui Province. Ophthalmic examinations and questionnaire surveys were conducted to obtain information on myopia, AL, AL/CR and participation in various types of extracurricular tutoring. A binary Logistic regression model was used to analyze the association between non-sports tutoring and screening myopia, and multiple linear regression models were used to examine the associations between non-sports tutoring and AL and AL/CR. Results: Among the surveyed students, the participation rate in non-sports extracurricular tutoring classes was 64.9% , and the overall prevalence of screening myopia was 39.1%. The average AL and AL/CR were (23.60± 1.01 ) mm and (3.00±0.12), respectively. Univariate analysis showed that students who attended non-sports, music, or academic tutoring classes for ≥2 h per week had higher risks of screening myopia and greater AL/CR values than non-participants (screening myopia: OR =1.38, 1.82, 1.55; AL/CR: β =0.01, 0.03, 0.03; all P <0.05). After adjusting for sex, grade, and participation in sports tutoring, multivariate analysis indicated that participation in non-sports and musical instrument tutoring classes for ≥2 h per week remained significantly associated with higher risks of screening myopia ( OR =1.26, 1.49, both P <0.05). Multiple linear regression showed that participation in musical instrument tutoring for ≥2 h per week was positively correlated with AL ( β=0.14, P < 0.05). Conclusions Participation in non-sports extracurricular tutoring is common among primary school students. Attending non-sports tutoring classes for ≥2 h per week increases the risk of screening myopia.

BACKGROUND: Chronic kidney disease (CKD)-associated anemia (CKD-anemia) is associated with poor survival, and hemoglobin targets are often not achieved with current therapies. Phase 3 trials have demonstrated the treatment efficacy of roxadustat for CKD-anemia. This phase 4 study aims to evaluate the long-term (52-week) safety and effectiveness of roxadustat in a broad real-world patient population with CKD-anemia with and without dialysis in China. METHODS: This Phase 4 multicenter, open-label, prospective study, conducted from 24 November 2020 to 11 November 2022, evaluated the long-term safety and effectiveness of roxadustat for CKD-anemia in China. Patients aged ≥18 years with CKD-anemia with or without dialysis were included. The initial oral dose was 70-120 mg (weight-based followed by dose adjustment) over 52 weeks. The primary endpoint was safety based on adverse events (AEs). The secondary endpoints were hemoglobin changes from baseline and the proportion of patients who achieved mean hemoglobin ≥100 g/L. Effectiveness evaluable populations 1 (EE1) and EE2 included roxadustat-naïve and previously roxadustat-treated patients, respectively. The safety analysis set (SAF) included all patients who received ≥1 occasion. RESULTS: The EE1, EE2, and SAF populations included 1804, 193, and 2021 patients, respectively. In the SAF, the mean age was 50 ± 14 years, and 1087 patients (53.8%) were male. Mean baseline hemoglobin was 96.9 ± 14.0 g/L in EE1 and 100.3 ± 12.9 g/L in EE2. In EE1, the mean (95% confidence interval) hemoglobin changes from baseline over weeks 24-36 and 36-52 were 14.2 (13.5-14.9) g/L and 14.3 (13.5-15.0) g/L, respectively. Over weeks 24-36 and 36-52, 83.3% and 86.1% of patients in EE1 and 82.7% and 84.7% in EE2 achieved mean hemoglobin ≥100 g/L, respectively. In the SAF, 1643 (81.3%) patients experienced treatment-emergent AEs (TEAEs). Overall, 219 (10.8%) patients experienced drug-related TEAEs. Thirty-eight (1.9%) patients died of TEAEs (unrelated to the study drug). Vascular access thrombosis was uncommon. CONCLUSIONS: Roxadustat (52 weeks) increased hemoglobin and maintained the treatment target in Chinese patients with CKD-anemia with acceptable safety, supporting its use in real-world settings.

Dynamic changes in the physiochemical, structural, and flavor characteristics of ginger-juice milk curd were explored by texture analysis, scanning electron microscopy, rheometry, electronic tongue, and gas chromatography-mass spectrometry (GC-MS). Protein electrophoresis showed that ginger juice could hydrolyze α_s-, β-, and κ-casein. Curd formation was initiated at 90 s, marked by significant changes in intensity detected via intrinsic fluorescence. The contents of soluble protein and calcium decreased rapidly during coagulation, while the caseinolytic activity, storage moduli, loss moduli, hardness, adhesiveness, and water-holding capacity increased, resulting in a denser gel structure with smaller pores and fewer cavitations as observed by scanning electron microscopy. Electronic tongue analysis indicated that milk could neutralize the astringency and saltiness of ginger juice, rendering the taste of ginger-juice milk curd more akin to that of milk. Approximately 70 volatile components were detected in ginger-juice milk curd. α‍-Zingiberene, α‍-curcumene, β‍-sesquiphellandrene, and β‍-bisabolene were the predominant volatile flavor compounds, exhibiting an initial decrease in content followed by stability after 90 s. Decanoic acid, γ-elemene, and caryophyllene were identified as unique volatile compounds after mixing of milk and ginger juice. Understanding the dynamic changes in these characteristics during coagulation holds significant importance for the production of ginger-juice milk curd.

Objective To study the three-dimensional changes of soft and hard tissue in male patients with unilateral non-syndromic cleft lip and palate in the mixed dentition period before and after maxillary protraction.Methods Twenty male patients with unilateral non-syndromic cleft lip and palate in the mixed dentition period treated by maxillary anterior traction in the Department of Orthodontics of Affiliated Stomatological Hospital of Nanjing Medical University were selected(average age(10.6±1.23)years old).Cone beam CT was taken before and after treatment.Dolphin 3D 11.95 software was used for three-dimensional measurement and analysis.SPSS 25.0 software package was used for statistical analysis.The self-controlled paired t test was used to compare the changes in soft and hard tis-sues of male patients with unilateral cleft lip and palate before and after treatment.The changes in the anterior displacement of the ANS point,the anterior displacement of point A,and the posterior displacement of point B were tested using the one-sample t test.Results The sagittal skeletal changes were significantly increased in ∠ SNA(P＜0.01),∠ANB(P＜0.01),Y axis(P＜0.05),the forward displacement of ANS point(P＜0.01)and A point(P＜0.01)and the backward displacement of B point(P＜0.01),but ∠SNB(P＜0.05)was decreased significantly.The vertical skeletal changes showed that ∠MP-FH(P＜0.01),∠MP-SN(P＜0.05)and the dis-tance of ANS-Me(P＜0.05)were increased significantly,but ∠SN-PP(P＜0.01)was decreased significantly.The dental changes inclu-ding ∠U1-NA(P＜0.01),the distance of U1-NA(P＜0.01),∠U1-SN(P＜0.01),overjet and the Wits were increased significantly,but ∠ L1-NB(P＜0.01),the distance of L1-NB(P＜0.01)and ∠L1-MP(P＜0.01)were decreased significantly.The changes of soft tis-sue including ∠ S-Ns-Sn(P＜0.01),∠ Sn-Ns-Bs(P＜0.01),the distance of UL-EP(P＜0.01)and LL-UL(P＜0.01)were increased sig-nificantly.Conclusion After the treatment of maxillary protraction,the forward growth of maxilla will be possibly promoted on patients with cleft lip and palate in the peak of growth timing,as well as the intermaxillary relationship and soft tissue profile,but the side effects should be paid attention to.

This study was aimed at investigating the effectiveness of various host nucleic acid removal and non-specific amplifica-tion techniques in animal tissue samples,to increase the accuracy of pathogen identification in tissue samples.Simulated samples were prepared with a mixture of mouse lung tissue homogenates and Klebsiella pneumoniae fluids,and processed with six host nucleic acid removal kits and three non-specific amplification techniques.The effectiveness of each method in removing host DNA and enriching nucleic acids of pathogenic microorganisms was evaluated through real-time fluorescence quantitative PCR and high-throughput se-quencing.For host nucleic acid removal techniques,the method of selective cleavage and quantitative degradation of host DNA(Com-plete5 kit)effectively decreased the host nucleic acid content in tissue samples and increased the relative abundance of pathogen nucleic acids.In contrast,the magnetic bead method for host DNA removal(Next microbiome DNA enrichment Kit kit)was less effec-tive.At lower pathogen concentrations(77 CFU/mL),the Vazyme kit was more effective than the other kits in removing host nucleic acids.Non-specific amplification techniques(MALBAC whole genome amplification,MDA isothermal amplification,and random primer amplification)were not applicable to tissue samples and were not effective in increasing the relative abundance of pathogen nucleic acids.Selective lysis and quantitative degradation of host DNA were suitable for processing tissue samples with high host back-ground and low pathogenic microorganism levels,whereas non-specific amplification methods were not applicable to tissue samples for pre-processing of macro-genome high-throughput sequencing.

Background: Whether there is a causal relationship between childhood obesity and increased risk of chronic kidney disease (CKD) remains controversial. This study sought to explore how body size in childhood and adulthood independently affects CKD risk in later life using a Mendelian randomization (MR) approach. Methods: Univariate and multivariate MR was used to estimate total and independent effects of body size exposures. Genetic associations with early-life and adult body size were obtained from a genome-wide association study of 453,169 participants in the U.K. Biobank, and genetic associations with CKD were obtained from the CKDGen and FinnGen consortia. Results: A larger genetically predicted early-life body size was associated with an increased risk of CKD (odds ratio [OR], 1.27; 95% confidence interval [CI], 1.14 to 1.41; P= 1.70E-05) and increased blood urea nitrogen (BUN) levels (β=0.010; 95% CI, 0.005 to 0.021; P=0.001). However, the association between the impact of early-life body size on CKD (OR, 1.12; 95% CI, 0.95 to 1.31; P=0.173) and BUN level (β=0.001; 95% CI, –0.010 to 0.012;P= 0.853) did not remain statistically significant after adjustment for adult body size. Larger genetically predicted adult body size was associated with an increased risk of CKD (OR, 1.37; 95% CI, 1.21 to 1.54; P= 4.60E-07), decreased estimated glomerular filtration rate (β=–0.011; 95% CI, –0.017 to –0.006; P=5.79E-05), and increased BUN level (β= 0.010; 95% CI, 0.002 to 0.019; P= 0.018). Conclusion Our research indicates that the significant correlation between early-life body size and CKD risk is likely due to maintaining a large body size into adulthood.

Objective:To investigate the clinical effects and advantages of laparoscopic total mesorectal excision in the treatment of colorectal cancer.Methods:A total of 82 patients with colorectal cancer who received treatment at the Second Affiliated Hospital of Guizhou Medical University from January 2020 to January 2023 were selected for a prospective study. They were randomly assigned to two groups using a random number table, with 41 cases in each group. The control group underwent conventional laparotomy, while the observation group received laparoscopic total mesorectal excision. Clinical efficacy, clinical indicators, and immune function indicators were compared between the two groups.Results:The operation time for patients in the observation group was (1.98 ± 0.31) hours, the length of hospital stay was (8.32 ± 2.38) days, the recovery time for bowel function was (2.15 ± 0.34) days, and the intraoperative blood loss was (112.35 ± 12.66) mL, all of which were shorter and lower than those in the control group [(2.46 ± 0.32) hours, (14.52 ± 2.42) days, (3.25 ± 0.15) days, and (167.78 ± 12.35) mL, t = 6.90, 11.70, 18.95, 20.07, all P < 0.001). The short-term response rate in the observation group was higher than that in the control group ( χ2 = 4.10, P < 0.05). The immune function indicators in the observation group, including the CD4 +/CD8 + ratio (1.78 ± 0.54), immunoglobulin A [(3.87 ± 0.73) g/L], and immunoglobulin G [(11.83 ± 2.88) g/L], were all better than those in the control group [(1.36 ± 0.53), (1.78 ± 0.63) g/L, (6.37 ± 2.45) g/L, t = 3.55, 13.88, 9.25, all P < 0.001]. The incidence of complications in the observation group was 2.44% (1/41), which was significantly lower than that in the control group [19.51% (8/41), χ2 = 4.49, P < 0.05]. Conclusions:Laparoscopic total mesorectal excision for patients with colorectal cancer has significant advantages, including faster recovery, less bleeding, and fewer complications, making it more superior to conventional laparotomy.
