AIM:To compare the changes in diopters and axial length after 1 a of wearing defocus incorporated multiple segments(DIMS)lenses or single vision(SV)spectacle lenses in children with monocular myopia.METHODS:In this retrospective case group study, monocular myopia children aged from 6 to 14 years old in Hankou Aier Eye Hospital from October 2020 to October 2022, who were fitted with DIMS lens(n=52)or single-vision(SV)spectacle lenses(n=49)were collected. The spherical degree of myopia eyes ranged from -4.00 D to -0.50 D and the nonmyopic eyes ranged from 0 to +1.00 D, astigmatism in all eyes ranged from 0 to -2.00 D. The DIMS lens group was classified into DIMS-myopia group(the myopic eyes)and DIMS-nonmyopia group(the nonmyopic eyes). The SV lens group was also divided into SV-myopia group and SV-nonmyopia group. The changes in spherical equivalent refraction(SER)and axial length(AL)of each group were compare before and after wearing lenses for 1 a, and variations in SER and AL of both eye among groups were analzed.RESULTS: After wearing lenses for 1 a, the changes of SER in the DIMS-myopic group and the DIMS-nonmyopic group were -0.41±0.44 and -0.26±0.54 D, respectively, and the changes of AL were 0.18±0.20 and 0.15±0.15 mm, respectively. SER changes were -0.74±0.63 and -0.70±0.68 D in SV-myopic group and SV-nonmyopic group, and AL changes were 0.30±0.28 and 0.31±0.28 mm. The changes of SER and AL in the DMS-myopic and non-myopic groups were slower than those in SV group(all P<0.05). Compared with SV lenses, wearing DIMS lenses delayed and 44.6% in myopia eyes, and 62.9% in non-myopia eyes, AL delayed by 40.0% in myopia eyes and 51.6% in non-myopia eyes. The percentage of 1-year AL change ≤0.2 mm in the DIMS-myopic group and non-myopic group was 53.9% and 65.4%, respectively, which was higher than that in the SV myopic group(34.7% and 42.9%, all P<0.05). The percentage of AL change >0.4 mm in the DIMS-myopic group and nonmyopic group was 17.3% and 7.7%, respectively, which was lower than that in the SV myopic group(32.7% and 28.6%, all P<0.05). There was no significant correlation between the change of AL and age and baseline AL in the DIMS-myopic and non-myopic groups after wearing lens for 1 a(all P>0.05); the change of AL in SV-myopic group and non-myopic group was negatively correlated with age(r=-0.446, P=0.001; r=-0.312, P=0.029), and there was no significant correlation with baseline AL(all P>0.05).CONCLUSION: DIMS lens has a good effect on myopia control and prevention in both myopia and non-myopia children with monocular myopia. Children with early pre-myopia can wear DIMS to prevent myopia.

Artemisia argyi (A. argyi), a plant with a longstanding history as a raw material for traditional medicine and functional diets in Asia, has been used traditionally to bathe and soak feet for its disinfectant and itch-relieving properties. Despite its widespread use, scientific evidence validating the antifungal efficacy of A. argyi water extract (AAWE) against dermatophytes, particularly Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporum gypseum, remains limited. This study aimed to substantiate the scientific basis of the folkloric use of A. argyi by evaluating the antifungal effects and the underlying molecular mechanisms of its active subfraction against dermatophytes. The results indicated that AAWE exhibited excellent antifungal effects against the three aforementioned dermatophyte species. The subfraction AAWE6, isolated using D101 macroporous resin, emerged as the most potent subfraction. The minimum inhibitory concentrations (MICs) of AAWE6 against T. rubrum, M. gypseum, and T. mentagrophytes were 312.5, 312.5, and 625 μg·mL-1, respectively. Transmission electron microscopy (TEM) results and assays of enzymes linked to cell wall integrity and cell membrane function indicated that AAWE6 could penetrate the external protective barrier of T. rubrum, creating breaches ("small holes"), and disrupt the internal mitochondrial structure ("granary"). Furthermore, transcriptome data, quantitative real-time PCR (RT-qPCR), and biochemical assays corroborated the severe disruption of mitochondrial function, evidenced by inhibited tricarboxylic acid (TCA) cycle and energy metabolism. Additionally, chemical characterization and molecular docking analyses identified flavonoids, primarily eupatilin (131.16 ± 4.52 mg·g-1) and jaceosidin (4.17 ± 0.18 mg·g-1), as the active components of AAWE6. In conclusion, the subfraction AAWE6 from A. argyi exerts antifungal effects against dermatophytes by disrupting mitochondrial morphology and function. This research validates the traditional use of A. argyi and provides scientific support for its anti-dermatophytic applications, as recognized in the Chinese patent (No. ZL202111161301.9).

OBJECTIVE To investigate the effects of renally inappropriate medication (RIM) on the frailty of elderly patients with diabetes. METHODS The data of elderly patients with diabetes mellitus admitted to a third-grade class A hospital in Yunnan province from January to December 2022 were collected, and Beers criteria (2019 edition) and Chinese version of FRAIL scale were used to evaluate RIM and the frailty of the patients; the patients were divided into the trial group (with RIM) and the control group (without RIM) according to whether there was RIM. The propensity score matching was used to balance confounding factors between two groups, and the influence of RIM on the frailty of elderly diabetic patients was analyzed by the Logistic regression model. RESULTS Among the 367 patients, 80 patients (21.80%) had RIM, the drugs involved RIM were spironolactone (82.56%), rivaroxaban (13.95%) and gabapentin (3.49%). After reaching the balance between groups using the propensity score matching method, the incidence of frailty was 77.94% in trial group and 27.94% in control group (P<0.001); the difference was not statistically significant in other confounding factors between the two groups (P>0.05). Results of Logistic regression analysis showed that the risk of frailty in the experimental group was 3.118 times that of the control group (odds ratio was 3.118,95% confidence interval was 1.758-5.530, P<0.001). CONCLUSIONS RIM is a risk factor for the frailty of elderly patients with diabetes, which can be considered as an indicator for early identification and screening of the frailty of elderly diabetes patients.

Cerebral ischemia-reperfusion injury (CIRI) has a very high incidence, disability, and mortality rates, which seriously affects human life and health. In recent years, modern medicine has made some progress in the diagnosis and treatment of CIRI, but there are still problems such as difficulties in postoperative rehabilitation and adverse drug reactions, and new therapeutic drugs for CIRI are urgently needed. As an important class of active ingredients in traditional Chinese medicine, flavonoids can play antioxidant, apoptosis inhibition, anti-inflammatory, and other pharmacological effects to improve brain tissue damage, which is important for improving the quality of life of CIRI patients and slowing down the aging of the social population. Numerous studies have found that flavonoids in traditional Chinese medicine can regulate cell surface receptors Toll-like receptor 4/nuclear factor-kappaB (TLR4/NF-κB), phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), adenylate-activated protein kinase/mammalian target of rapamycin protein (AMPK/mTOR), Ras homologous gene family member A/Rho-associated coiled-coil protein kinase (RhoA/ROCK), nuclear factor E2-associated factor 2/Kelch-like epoxychloropropane-associated protein-1/haemoglobin oxygenase 1 (Nrf2/Keap1/ HO-1), Notch, and other signaling pathways, so as to regulate the transcription and expression of related proteins after CIRI, alleviate brain tissue injury, and improve CIRI. This paper analyzed the relevant literature in China and abroad in recent years, reviewed the mechanism of action and related pathways of flavonoids in traditional Chinese medicine to improve CIRI, and explored the new therapeutic direction of CIRI at the metabolic level, with a view to providing a basis for the further development and application of flavonoids in traditional Chinese medicine.

To explore the relationship between metal exposure level and blood pressure, so as to provide a scientific basis for verifying the relationship between metal exposure and elevated blood pressure among primary school students.
Methods:
In July 2022, a total of 555 students of second to sixth grade were selected by cluster random sampling method from two primary schools in Zhuxi County, Shiyan City, Hubei Province. A questionnaire survey was conducted to obtain the socio demographic characteristics and living habits of the participants. The height, weight, body mass index(BMI) and blood pressure were obtained by physical examination. At the same time, the urine of the subjects was collected, and the metal mass fraction in urine was detected by inductively coupled plasma mass spectrometry. The relationship between metal mass fraction in urine and blood pressure was analyzed by generalized linear regression.
Results:
The detection rate of elevated blood pressure in primary school students was 15.86% , and there was a statistically significant difference in the detection rate of elevated blood pressure among obese primary school students (yes:37.25%,no:13.69%, χ 2=19.28, P <0.01).There were statistically significant differences in BMI[15.80( 14.69 , 17.92 ),17.87(15.49,20.89)kg/m 2] between the non elevated blood pressure group and the elevated blood pressure group of elementary school students ( Z =-4.67, P <0.01). The geometric mean mass fraction of zinc in urine was the highest ( 6 942.86 μg/g), titanium was the lowest (2.20 μg/g). Zinc and lead were positively correlated with elevated systolic blood pressure( β = 0.054 , 0.014), zinc and cadmium were positively correlated with elevated diastolic blood pressure ( β =0.038,0.029) ( P <0.05).
Conclusions
Metal zinc, lead and cadmium concentration are associated with elevated blood pressure. It is necessary to intervene and control the exposure of zinc, lead and cadmium in the environment to promote the blood pressure health of primary school students.

Tumor cells use glycolysis to provide material and energy under hypoxic conditions to meet the energy requirements for rapid growth and proliferation, namely the Warburg effect. Even under aerobic conditions, tumor cells mainly rely on glycolysis to provide energy. Therefore, glucose transporter protein 1(GLUT1), which is involved in the process of glucose metabolism, plays an important role in tumorigenesis, development and drug resistance, and is considered to be one of the important targets in the treatment of malignant tumors. In recent years, research on tumor glucose metabolism has gradually become a hot spot. It has been shown that various factors are involved in the regulation of tumor energy metabolism, among which the role of GLUT1 is the most critical. In this paper, the authors reviewed the latest research progress of GLUT1-targeted traditional Chinese medicine(TCM) active ingredient nano-delivery system in tumor therapy, aiming to reveal the feasibility and effectiveness of this system in the delivery of chemotherapeutic drugs. The GLUT1-targeted TCM active ingredient nano-delivery system can overcome the bottleneck of the traditional targeting strategy as well as the high-permeability long retention(EPR) effect. In summary, the authors believe that the GLUT1-targeted TCM active ingredient nano-delivery system provides a new strategy for targeted treatment of tumors and has a broad application prospect in tumor prevention and treatment.
