Abstract The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas：optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

The plateau region is known for its unique environmental characteristics of low oxygen, low pressure, strong radiation, cold and dryness. Under the low oxygen environment, human physiological functions and drug metabolism are significantly affected. In order to gain a deeper understanding of drug metabolism in the plateau hypoxic environment and to guide the rational use of drugs in the plateau region, the effects of plateau hypoxia on drug metabolism were reviewed in this paper, which focused on changes in metabolic profiles, enzyme activity and expression, and probed the relevant mechanisms in depth.

Objective To investigate the impacts of percutaneous endoscopic interlaminar discectomy(PEID)on pain level and lumbar function in patients with lumbar disc herniation(LDH).Methods From January 2022 to August 2023,84 patients were diagnosed with L4/5 LDH based on clinical data and imaging information were selected as the study subjects.And they were assigned into 42 cases in experimental group and 42 cases in traditional groups complying with treatment methods.The traditional group underwent traditional open approach treatment,while the experimental group underwent PEID.The surgical indicators(including hospitalization time,surgical time,bed rest time,and intraoperative fluoroscopy frequency),the levels of interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α)were compared between the two groups,the visual analogue scale(VAS)score and Oswestry disability index(ODI)were used to quantify the pain level of waist and lower limbs and lumbar function,and the excellent and good rate of clinical satisfaction and the incidence of complications were compared.Results The hospitalization time and bed rest time of the experimental group were obviously shorter than those of the traditional group,while the fluoroscopy frequency was less than that of the traditional group,and surgical time was longer than that of the traditional group,the differences were statistically significant(P＜0.05).After treatment,the pain VAS score and ODI of waist and lower limbs,the IL-6,and TNF-α in the two groups were lower than those before treatment,the experimental group was lower than the traditional group,the differences were statistically significant(P＜0.05).The excellent and good rate of the experimental group and the traditional group were 88.10％and 83.33％,respectively,with no statistically significant difference(P＞0.05).There was no statistically significant difference in the total incidence of complications between the two groups(P＞0.05).Conclusion PEID surgery can effectively alleviate nerve compression,alleviate pain of waist and lower limbs,promote the recovering of lumbar function,and facilitate postoperative recovery in LDH patients.

Objective:To investigate the diagnostic value of metagenomic next-generation sequencing (mNGS) for pyogenic spinal infections.Methods:A total of 255 patients diagnosed with pyogenic spinal infections were enrolled between September 2022 and September 2024 at Qingdao University Affiliated Hospital, Fuzhou Second General Hospital, First Affiliated Hospital of Nanchang University, Shandong University Affiliated Public Health Clinical Center, and the Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. Among them, 155 were male and 100 were female, with an average age of 62.5±14.2 years (ranging from 13 to 90 years). All patients had samples of infected tissue and/or pus collected for microbial culture and mNGS testing. The number, types, and positive rates of pathogens detected by microbial culture and mNGS were compared. Using culture results as the gold standard, receiver operating characteristic (ROC) curve analysis was performed for mNGS testing and the combined method of mNGS and microbial culture, calculating the area under the curve (AUC) and 95% CI. Results:All 255 cases were clinically diagnosed as pyogenic spinal infections, with 194 cases providing microbiological evidence. The most common Gram-positive bacterium was Staphylococcus aureus, while the most common Gram-negative bacterium was Escherichia coli. A total of 33 pathogenic microorganisms were detected by mNGS, while microbial culture detected 18 pathogenic microorganisms. The positive rate of mNGS was 72.2% (184 out of 255), which was significantly higher than that of 30.2% (77 out of 255) for microbial culture, showing a significant difference (χ 2=90.150, P<0.001); the positive rate of mNGS combined with microbial culture was 76.1% (194 out of 255) with significant difference compared to mNGS alone (χ 2=8.100, P<0.001). Among 178 culture-negative samples, the detection rate of mNGS was 65.7% (117 out of 178); among 77 culture-positive samples, the detection rate of mNGS was 87.0% (67 out of 77), and 97.0% (65 out of 67) of the detected pathogens matched the culture results at the species level. The AUCs of the ROC curves for mNGS testing and the combination of mNGS with microbial culture were 0.606 [95% CI (0.534, 0.678)] and 0.671 [95% CI (0.606, 0.736)], respectively, with significant differences compared to microbial culture ( P=0.007; P=0.007). Conclusions:mNGS demonstrates superior performance over conventional culture in identifying pathogens in pyogenic spinal infections. Moreover, combining mNGS with culture further improves diagnostic yield, supporting its integration into clinical practice.

This report described a case of eclampsia complicated by hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome with refractory hepatic impairment. The patient presented at 34 +6 weeks' gestation with convulsions and impaired consciousness for over 3 hours, accompanied by severe hypertension [240/120 mmHg (1 mmHg=0.133 kPa)]. Emergency cesarean delivery was performed at a local hospital. On postoperative day 2, the patient was transferred to our institution due to sharp transaminase elevation, hepatic failure, and coagulopathy. Although treated with artificial liver support, anti-infection therapy, and organ protection measures, hepatic parameters showed intermittent rebounds. Subsequent detection of cytomegalovirus in bronchoalveolar lavage fluid and blood prompted targeted antiviral therapy, which significantly improved hepatic injury. Through multidisciplinary management, the patient recovered and was discharged 43 days postpartum. Although multiple artificial liver sessions provided limited hepatic function improvement, this case offers valuable insights for managing refractory hepatic impairment in pregnant women, regardless of whether viral infection represented a primary etiology or secondary complication.
