OBJECTIVE: To observe the clinical effect of acupuncture and moxibustion combined with umbilical therapy on anxiety and depression in patients with neurogenic bladder (NB) after spinal cord injury (SCI). METHODS: Thirty cases of NB after SCI with anxiety and depression were selected and treated with acupuncture and moxibustion combined with umbilical therapy. Acupuncture was applied at Baihui (GV20), Yintang (GV24⁺), Sanyinjiao (SP6), Shenmen (HT7), Hegu (LI4), Taichong (LR3), once a day, continuous treatment for 4 weeks. Ginger moxibustion was applied at the bladder meridian of foot taiyang and governor vessel, once a day, continuous treatment for 4 weeks. In treatment of umbilical therapy, Chaihu (Radix Bupleuri), Yujin (Radix Curcumae), Rougui (Cortex Cinnamomi) were ground and mixed with the same amount of honey, put into the application, and the application was placed on the navel after filling the navel with fine salt, once a day for 4 weeks. Hamilton anxiety scale (HAMA) score, Hamilton depression scale (HAMD) score, urodynamic indexes (maximum urinary flow rate [Qmax], maximum detrusor pressure [Pdet-max], residual urine volume [RUV]), neurogenic bladder symptom score (NBSS), urinary symptom distress scale (USDS) score were compared before and after treatment, and the clinical efficacy was evaluated. RESULTS: After treatment, the scores of HAMA, HAMD, NBSS, USDS and RUVwere lower than those before treatment (P<0.05), and Qmax and Pdet-max were higher than those before treatment (P<0.05). The total effective rate was 93.3 (28/30). CONCLUSION Acupuncture and moxibustion combined with umbilical therapy can effectively relieve anxiety and depression symptoms, improve urination disorders in patients with NB after SCI.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.

OBJECTIVES: To investigate the mechanism through which pinostrobin (PSB) alleviates dextran sulfate sodium (DSS)-induced colitis in mice. METHODS: C57BL/6 mice were randomized into control group, DSS model group, and PSB intervention (30, 60, and 120 mg/kg) groups. Colitis severity of the mice was assessed by examining body weight changes, disease activity index (DAI), colon length, and histopathology. The expressions of tight junction proteins ZO-1 and claudin-1 in the colon tissues were examined using immunofluorescence staining, and macrophage infiltration and polarization were analyzed with flow cytometry. ELISA and RT-qPCR were used for detecting the expressions of inflammatory factors (TNF‑α and IL-6) and chemokines (CCL₂, CXCL₁₀, and CX₃CL₁) in the colon tissues, and PI3K/AKT phosphorylation levels were analyzed with Western blotting. In cultured Caco-2 and RAW264.7 cells, the effect of PSB on CCL₂-mediated macrophage migration was assessed using Transwell assay. Network pharmacology analysis was performed to predict the key pathways that mediate the therapeutic effect of PSB. RESULTS: In DSS-induced mouse models, PSB at 60 mg/kg optimally alleviated colitis, shown by reduced weight loss and DAI scores and increased colon length. PSB treatment significantly upregulated ZO-1 and claudin-1 expressions in the colon tissues, inhibited colonic macrophage infiltration, and promoted the shift of macrophage polarization from M1 to M2 type. In cultured intestinal epithelial cells, PSB significantly inhibited PI3K/AKT phosphorylation and suppressed chemokine CCL₂ expression. PSB treatment obviously blocked CCL₂-mediated macrophage migration of RAW264.7 cells, which could be reversed by exogenous CCL₂. Network pharmacology analysis and rescue experiments confirmed PI3K/AKT and CCL₂ signaling as the core targets of PSB. CONCLUSIONS PSB alleviates DSS-induced colitis in mice by targeting intestinal epithelial PI3K/AKT signaling, reducing CCL₂ secretion, and blocking macrophage chemotaxis and migration, highlighting the potential of PSB as a novel natural compound for treatment of inflammatory bowel disease.

Objective To optimize the oxygen therapy regimens for infants with pulmonary diseases during bronchoscopy.Methods A prospective randomized,controlled,and single-center clinical trial was conducted on 42 infants who underwent electronic bronchoscopy from July 2019 to July 2021.These infants were divided into a nasal cannula(NC)group and a modified T-piece resuscitator(TPR)group using a random number table.The lowest intraoperative blood oxygen saturation was recorded as the primary outcome,and intraoperative heart rate and respiratory results were recorded as the secondary outcomes.Results Compared with the NC group,the modified TPR group had a significantly higher level of minimum oxygen saturation during surgery and a significantly lower incidence rate of hypoxemia(P<0.05).In the modified TPR group,there were 6 infants with mild hypoxemia,2 with moderate hypoxemia,and 1 with severe hypoxemia,while in the NC group,there were 3 infants with mild hypoxemia,5 with moderate hypoxemia,and 9 with severe hypoxemia(P<0.05).The modified TPR group had a significantly lower incidence rate of intraoperative respiratory rhythm abnormalities than the NC group(P<0.05),but there was no significant difference in the incidence rate of arrhythmias between the two groups(P>0.05).Conclusions Modified TPR can significantly reduce the risk of hypoxemia in infants with pulmonary diseases during electronic bronchoscopy,and TPR significantly decreases the severity of hypoxemia and the incidence of respiratory rhythm abnormalities compared with traditional NC.

AIM: To assess the gap between the peak of the base curve to the surface of the cornea, as well as examines the correlation between the thickness of the tear film and the fitting of the orthokeratology lens through optical coherence tomography(OCT), providing an intuitive and quantitative clinical evaluation method for the fitting of the orthokeratology lens.METHODS: Myopia patients who fitted orthokeratology at our hospital from January to December 2023 were included. Examinations, including naked vision, slit lamp, non-contact intraocular pressure, ocular fundus, eye position, corneal diameter, corneal topography, tear film rupture time, optometry, etc., were performed on all patients before fitting. The trial lens parameter was selected according to the examination results, and fluorescein staining was performed to evaluate lens fitting state after patients adapted to wearing glasses. According to the performance of fluorescein staining, the inspected eyes are divided into three groups: lens loose group, lens fitting group, and lens tight group. In addition, the tear film thickness of three groups of subjects was measured by OCT, and the differences between the three groups of data were evaluated.RESULTS: A total of 49 myopic patients(77 eyes)were included. The average sphere degree was -3.10±1.25 D, the average cylinder degree was -0.43(-0.75, 0)D, the average horizontal keratometry(HK)was 42.48±0.81 D, and vertical keratometry(VK)was 42.98(42.25, 43.50)D. There were 21 cases(34 eyes)in the lens fitting group, with 13 cases of bilateral eyes, 8 cases of one eye, 14 cases(22 eyes)in the lens loose group, with 8 cases of bilateral eyes, 6 cases of one eye, and 14 cases(21 eyes)in the lens tight group, with 7 cases of bilateral eyes, 7 cases of one eye. There was no statistical difference in the main basic data of the subjects in the three groups(all P>0.05). OCT showed that the tear film thickness of the lens fitting group, the lens loose group, and the lens tight group was 231.18(219.0, 243.0), 220.41(214.0, 224.3), and 249.00(241.5, 258.0)μm, respectively, and there was statistical significance in the thickness among the three groups(P<0.05).CONCLUSION: OCT can serve as a safe and reliable method for measuring the tear film thickness, which can help evaluate the suitability of orthokeratology and provide a non-invasive, more intuitive, and quantitative evaluation method for the fitting and evaluation of orthokeratology.

Objective:To investigate the iodine nutrition levels of children aged 8 - 10 and pregnant women in iodine deficient areas and iodine adequate areas of Inner Mongolia Autonomous Region (Inner Mongolia for short), and to provide scientific basis for prevention and treatment of iodine deficiency disorders.Methods:From March to July 2022, iodine nutrition analysis was conducted in iodine deficient areas and iodine adequate areas of 104 banners (counties, cities and districts) in 12 league cities in Inner Mongolia. Each monitoring banner (county, city and district) was divided into five sampling areas by east, west, south, north, and center, with one Sumu (township, street) selected from each area. One primary school was selected from each Sumu (township, street), and 40 non-boarding students aged 8 - 10 were selected from each primary school. One third of the students underwent thyroid ultrasound examination. Twenty pregnant women were selected from each of the 5 Sumus (townships, streets) in each monitoring banner (county, city and district). Household salt samples and random urine samples of children and pregnant women were collected to detect salt iodine and urinary iodine levels.Results:In 2022, the median thyroid volume of children aged 8 - 10 in iodine deficient areas and iodine adequate areas of Inner Mongolia was 2.44 ml, and the goiter rate was 1.89% (123/6 496). There were statistically significant differences in thyroid volume and goiter rate between different league cities ( H = 1 229.05, χ 2 = 34.13, P < 0.001). The coverage rate of iodized salt in 12 league cities was 98.51% (30 628/31 090), the consumption rate of qualified iodized salt was 94.42% (29 355/31 090), and the median salt iodine was 22.80 mg/kg. The median urinary iodine of children ( n = 20 968) was 195.00 μg/L, among which the median urinary iodine in 7 league cities was at the appropriate level of iodine nutrition (100 - 199 μg/L), and the median urinary iodine in 5 league cities was at the level of iodine nutrition exceeding the appropriate level (200 - 299 μg/L). The median urinary iodine of pregnant women ( n = 10 122) was 168.00 μg/L, among which, except for Bayannur (149.18 μg/L), the median urinary iodine in other 11 league cities was at the appropriate level of iodine nutrition (150 - 249 μg/L). Conclusions:The overall iodine nutrition of children and pregnant women in Inner Mongolia is at an appropriate level, but some pregnant women still face the risk of iodine deficiency. In the future, the focus of iodine deficiency disorders prevention and control should be on iodine nutrition monitoring for special needs populations.

;Aim To investigate the molecular mechanism of miR-326 inhibiting breast cancer invasion and metastasis by regulating EphB3 expression. Methods RTFQ-PCR was used to examine the expression of miR-326 in normal breast epithelial cells and breast cancer cells and the transfection efficiency of miR-326 overexpression plasmid. EdU cell proliferation assay and Transwell assay were used to examine the changes in proliferation, migration and invasion ability of different subgroups of cells. Dual luciferase assay was used to verify the presence of binding sites for miR-326 and EphB3. Western blot was used to detect the expression of EphB3 in breast cancer cells after overexpression of miR-326. Results RTFQ-PCR results showed that miR-326 was lowly expressed in breast cancer cells and successfully transfected (P < 0. 05). EdU proliferation assay and Transwell assay results showed that overexpression of miR-326 in breast cancer cells inhibited proliferation, migration and invasive ability (P < 0. 05). The results of dual luciferase assay showed that miR-326 could interact with the 3'-UTR of EphB3 (P < 0. 05). Western blot and Transwell assays showed that miR-326 could negatively regulate EphB3 to inhibit invasive metastasis of breast cancer cells (P < 0. 05). Conclusions MiR-326 acts as a cancer suppressor genes in the development of breast cancer and suppresses the invasion and metastasis of breast cancer cells by regulating the expression of EphB3.

Random urine samples and household salt samples were collected to detect iodine content. At the same time, 1/3 of the selected children were selected for thyroid B-ultrasound examination to measure thyroid volume.Results:In 2021, a total of 19 968 children aged 8 - 10 in non-high water iodine areas of Inner Mongolia were monitored, and 19 968 urine samples were collected, with a median urine iodine of 199.23 μg/L. There was a statistically significant difference in the frequency distribution of urinary iodine in different cities (χ 2 = 839.51, P < 0.001). The median iodine content of children's household edible salt was 22.64 mg/kg, and the coverage rate of iodized salt, qualified iodized salt coverage rate, and non-iodized salt rate in the entire region was 99.05% (19 778/19 968), 94.98% (18 785/19 778), 94.08% (18 785/19 968) and 0.95% (190/19 968), respectively. Thyroid B-ultrasound were performed in 6553 children, the goiter rate was 1.30% (85/6 553), and there were statistically significant differences in goiter rates among children of different ages and cities (χ 2 = 87.09, P < 0.001; χ 2 = 10.40, P = 0.006) . Conclusions:In 2021, the iodine nutrition of children aged 8 - 10 in non-high water iodine areas of Inner Mongolia is at an appropriate level. However, in the future we should continue to adhere to the monitoring of iodine deficiency disorders, strengthen health education on iodine deficiency disorders, consolidate existing achievements in iodine deficiency disease prevention and control, and achieve the goal of continuous elimination of iodine deficiency disorders.
