Objective:
To understand the current situation and related factors of screening myopia among students in special education schools, so as to provide evidence for promoting the health level of this population.
Methods:
From November 2021 to December 2023, a total of 281 students from 6 special education schools in 5 districts of Tianjin were selected by cluster random sampling method for computer optometry visual acuity examination for non ciliary paralysis and questionnaire survey. Multiple Logistic regression was performed to analyze the influencing factors of screening myopia among special education students.
Results:
The screening myopia detection rate among these special education students in Tianjin was 27.0%, and the screening myopia detection rates of students with autism, developmental delays, and intellectual disabilities were 22.4%, 12.5%, and 33.0%, respectively. The degree of myopia increased with age ( χ 2 trend =22.65, P <0.01). Multivariate Logistic regression analysis showed that age(10-13 years old: OR =5.40, 14-17 years old: OR =8.40, 18-23 years old: OR =6.02), accommodation(non resident: OR =0.29), daily mobile phone usage ≥2 hours ( OR =2.37), and daily computer/tablet usage ≥2 hours ( OR =2.70) were the risk factors for screening myopia among special education students ( P <0.05).
Conclusions
The detection rate and degree of screening myopia increase with age in special education students. Prolonged screen time exposure is a primary risk factor for screening myopia in special education students. Effective myopia prevention and control strategies should be designed according to the characteristics of special education students.

OBJECTIVE To investigate the effects of Estradiol tablet/Estradiol and dydrogesterone tablet combined with Dan’e fukang decoction on postoperative recovery, sex hormone levels, uterine artery blood flow, and endometrium in patients with high risk of endometrial basal layer injury after induced abortion, and evaluate the safety of drug use. METHODS A retrospective analysis was conducted on the clinical data of 244 patients with high risk of endometrial basal layer injury who underwent artificial abortions in our hospital between January 2022 and December 2023. They were divided into control group (120 cases) and observation group (124 cases) according to postoperative medication plan. All patients received anti-infective treatment after induced abortion. Based on it, control group was given Estradiol tablet/Estradiol and dydrogesterone tablet, and observation group was given Estradiol tablet/Estradiol and dydrogesterone tablet+Dan’e fukang decoction, for consecutive 28 d. The time of vaginal bleeding, abdominal pain, return of menstruation, and vaginal bleeding volume were observed in 2 groups; serum sex hormone levels [serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and progesterone], uterine artery blood flow parameters [peak systolic blood flow velocity (PSV), pulsatility index (PI), and resistance index (RI)] and endometrial thickness were compared between the two groups before and after treatment. The occurrence of complications and adverse reactions in patients were recorded. RESULTS After treatment, the duration of vaginal bleeding, vaginal bleeding volume, duration of abdominal pain, and menstrual cycle recovery time in observation group were significantly shorter or less than the control group (P<0.05). After treatment, both groups exhibited a significant increase in endometrial thickness, serum FSH and LH levels, and PSV, compared to before treatment, and the observation group was significantly thicker/higher than the control group (P<0.05); the levels of estradiol and progesterone, as well as the values of PI and RI, were significantly lower than those before treatment, and the observation group was significantly lower than the control group (P<0.05). The total incidence of postoperative complications in observation group was significantly lower than control group (P<0.05), but there was no significant difference in the total incidence of adverse reactions between the 2 groups (P>0.05). CONCLUSIONS Estradiol tablet/Estradiol and dydrogesterone tablet combined with Dan’e fukang decoction can accelerate the postoperative recovery of patients with high risk of endometrial basal layer injury after induced abortion, promote endometrial growth, regulate serum sex hormone levels, improve uterine artery blood flow, reduce postoperative complications, and have good safety.

ObjectiveTo investigate the effect and potential mechanism of caffeic acid (CA) on severe acute pancreatitis (SAP) induced by caerulein combined with lipopolysaccharide (LPS), and to provide a basis for the research on novel drugs for the treatment of SAP. MethodsC57BL/6J mice, aged 6 weeks, were divided into control group, model group, CA group, and octreotide acetate (OA) group, with 6 mice in each group. The mice in the control group were given injection of normal saline, and those in the other groups were given intraperitoneal injection of caerulein combined with LPS to establish a mouse model of SAP. At 1 hour after the first injection of caerulein, the mice in the CA group and the OA group were given intraperitoneal injection of CA or subcutaneous injection of OA at an interval of 8 hours. The general status of the mice was observed after 24 hours of modeling, and serum, pancreas, lung, and colon samples were collected. HE staining was used to observe the histopathological changes of the pancreas and lungs, and the serum levels of α-amylase, lipase, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), alanine aminotransferase, aspartate aminotransferase, and creatinine were measured. RT-PCR was used to measure the expression of proinflammatory factors in the pancreas and lungs; myeloperoxidase (MPO) immunohistochemistry was used to observe the degree of neutrophil infiltration; Western blot was used to measure the activation of nuclear factor-kappa B (NF-κB) and the level of citrullinated histone H3 (CitH3), a marker for the formation of neutrophil extracellular traps (NETs), in the pancreas and lungs, as well as the expression level of ZO-1 in colon tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the Dunnett’s t-test was used for further comparison between two groups. ResultsCompared with the control group, the model group had severe injury in the pancreas and lungs and significant increases in the activity of serum α- amylase and lipase and the levels of the proinflammatory cytokines IL-6, interleukin-1β (IL-1β), and TNF-α in serum and lung tissue (all P<0.05), as well as significant increases in NF-κB activation, neutrophil infiltration, and the formation of NETs in the pancreas and lungs (all P<0.05). Compared with the model group, the CA group had alleviated pathological injury of the pancreas and lungs and significant reductions in the activity of serum α-amylase and the levels of the proinflammatory cytokines IL-6, IL-1β, and TNF-α in serum and lung tissue (all P<0.05), as well as significant reductions in NF-κB activation, neutrophil infiltration, and the formation of NETs in the pancreas and lungs (all P<0.05). ConclusionCA can alleviate SAP induced by caerulein combined with LPS in mice, possibly by inhibiting neutrophil recruitment and the formation of NETs.

Objective:
To investigate the role and mechanism of the heat-clearing and detoxifying drug Laggerae Herba in regulating the nuclear factor-erythroid 2-related factor-2(Nrf2)/solute carrier family 7 member 11 (SLC7A11)/glutathione peroxidase 4 (GPX4) signaling pathway to inhibit ferroptosis and improve chronic heart failure induced by transverse aortic arch constriction in mice.
Methods:
Twenty-four male ICR mice were divided into the sham (n=6) and transverse aortic arch constriction groups (n=18) according to the random number table method. The transverse aortic arch constriction group underwent transverse aortic constriction surgery to establish models. After modeling, the transverse aortic arch constriction group was further divided into the model, captopril, and Laggerae Herba groups according to the random number table method, with six mice per group. The captopril (15 mg/kg) and Laggerae Herba groups (1.95 g/kg) received the corresponding drugs by gavage, whereas the sham operation and model groups were administered the same volume of ultrapure water by gavage once a day for four consecutive weeks. After treatment, the cardiac function indexes of mice in each group were detected using ultrasound. The heart mass and tibia length were measured to calculate the ratio of heart weight to tibia length. Hematoxylin and eosin staining were used to observe the pathological changes in myocardial tissue. Masson staining was used to observe the degree of myocardial fibrosis. Wheat germ agglutinin staining was used to observe the degree of myocardial cell hypertrophy. Prussian blue staining was used to observe the iron deposition in myocardial tissue. An enzyme-linked immunosorbent assay was used to detect the amino-terminal pro-brain natriuretic peptide (NT-proBNP) and glutathione (GSH) contents in mice serum. Colorimetry was used to detect the malondialdehyde (MDA) content in mice serum. Western blotting was used to detect the Nrf2, GPX4, SLC7A11, and ferritin heavy chain 1 (FTH1) protein expressions in mice cardiac tissue.
Results:
Compared with the sham group, in the model group, the ejection fraction (EF) and fractional shortening (FS) of mice decreased, the left ventricular end-systolic volume (LVESV) and left ventricular end-systolic diameter (LVESD) increased, the left ventricular anterior wall end-systolic thickness (LVAWs) and left ventricular posterior wall end-systolic thickness (LVPWs) decreased, the ratio of heart weight to tibia length increased, the myocardial tissue morphology changed, myocardial fibrosis increased, the cross-sectional area of myocardial cells increased, iron deposition appeared in myocardial tissue, the serum NT-proBNP and MDA levels increased, the GSH level decreased, and Nrf2, GPX4, SLC7A11, and FTH1 protein expressions in cardiac tissue decreased (P<0.05). Compared with the model group, in the captopril and Laggerae Herba groups, the EF, FS, and LVAWs increased, the LVESV and LVESD decreased, the ratio of heart weight to tibia length decreased, the myocardial cells were arranged neatly, the degree of myocardial fibrosis decreased, the cross-sectional area of myocardial cells decreased, the serum NT-proBNP level decreased, and the GSH level increased. Compared with the model group, the LVPWs increased, the iron deposition in myocardial tissue decreased, the serum MDA level decreased, and Nrf2, GPX4, SLC7A11, and FTH1 protein expressions in cardiac tissue increased (P<0.05) in the Laggerae Herba group.
Conclusion
Laggerae Herba improves the cardiac function of mice with chronic heart failure caused by transverse aortic arch constriction, reduces the pathological remodeling of the heart, and reduces fibrosis. Its mechanism may be related to Nrf2/SLC7A11/GPX4 pathway-mediated ferroptosis.

Stroke is one of the leading causes of death and disability worldwide, ranking as the second leading cause of mortality globally and the primary cause of adult disability. Its pathological process involves complex cascade mechanisms, with high incidence and disability rates, posing a major threat to human health. According to statistics from the World Health Organization, more than 13 million new cases of stroke occur globally each year, resulting in direct medical costs and socioeconomic burdens amounting to hundreds of billions of dollars. In recent years, breakthroughs in the study of programmed cell death mechanisms have provided new insights into stroke treatment. Among them, ferroptosis, a novel form of cell death driven by iron-dependent lipid peroxidation, has attracted widespread attention in the pathological process of stroke. Ferroptosis is closely associated with iron metabolism disorders, oxidative stress, and lipid peroxidation, and exhibits unique regulatory effects in key pathological processes of stroke, such as ischemia-reperfusion injury, disruption of the blood-brain barrier, and neuronal apoptosis. It plays an important role in post-stroke neurological damage. Chinese medicine, as an essential component of traditional Chinese medicine (TCM), has demonstrated advantages in modulating ferroptosis and exerting neuroprotective effects. This review systematically summarizes current research on the neuroprotective mechanisms of Chinese medicine compound formulas and monomers through the regulation of ferroptosis pathways in post-stroke conditions, aiming to provide a basis for optimizing clinical treatment strategies and exploring new therapeutic approaches, and to offer new strategies and approaches for stroke treatment.

OBJECTIVE To explore the effects of Polygala tenuifolia compatibility on toxicity, anti-inflammatory and analgesic efficacy of sand-ironing Strychnos nux-vomica (SS). METHODS The preparation of SS single decoction, SS-P. tenuifolia core-removed (PC) (1∶2.5) or (1∶5) combined decoction, and SS-PC (1∶5) mixture were carried out to investigate their median lethal dose (LD50). Using aspirin as positive control, the number of writhing movements, analgesic rate, pain latency, ear swelling degree and inflammation inhibition rate induced by the above-mentioned medicinal liquids in mice were compared. The contents of the active and toxic components, strychnine and brucine, in the above-mentioned medicinal liquids were also determined. RESULTS The LD50 values of SS single decoction, SS-PC (1∶2.5) combined decoction, SS-PC (1∶5) combined decoction and SS- PC (1∶5) mixture were 302.00, 614.47, 1 445.44 and 1 778.28 mg/kg, respectively. Compared with control group, the number of writhing movements and ear swelling degree in the mice of the above-mentioned medicinal liquid groups were reduced or decreased significantly (P<0.05 or P<0.01); pain latency [at 90 and 120 minutes in the SS single decoction group, at 60 and 90 minutes in the SS-PC (1∶2.5) combined decoction group, and at 60,90, 120 minutes in the SS-PC (1∶5) combined decoction group and SS-PC (1∶5) mixture group] was significantly prolonged (P<0.05 or P<0.01); analgesic rates of the respective medicinal liquids were 39.30%, 70.87%, 80.00% and 82.46%, and inflammation inhibition rates were 38.08%,TD 57.89%, 76.47% and 50.46%; analgesic and anti-inflammatory effects of combined decoction and mixture were generally better than those of the single decoction (P<0.05 or P<0.01). In the above-mentioned four medicinal liquids, the total contents of strychnine were 0.71%, 0.42%, 0.47% and 0.64%, and the total contents of brucine were 0.88%, 0.63%, 0.57% and 0.88%, respectively. CONCLUSIONS The combination of P. tenuifolia can reduce the toxicity of SS and enhance its anti-inflammatory and analgesic effects. Moreover, there is a tendency for the toxicity-reducing and efficacy-enhancing effects to increase with the increasing dosage of P. tenuifolia. Additionally, the combined decoction of SS and P. tenuifolia can reduce the contents of the active and toxic components, strychnine and brucine, in SS.
