Pathologic myopia(PM)is characterized by progressive axial elongation, posterior staphyloma, and fundus degenerative changes, representing a leading cause of blindness in Asian countries.Posterior scleral reinforcement(PSR)is currently the only surgical intervention to slow axial elongation. Its mechanisms involve mechanical reinforcement, improved blood circulation, and biological stimulation of scleral remodeling. This article reviews recent advances in PSR: surgical techniques have evolved from complex, classic procedures to standardized single-strip methods, incorporating 3D MRI to quantify posterior staphyloma morphology for personalized graft design and facilitating minimally invasive, precision surgery. Among implant materials, biomaterials such as allogeneic dura mater are being continuously optimized, while biomimetic piezoelectric smart materials actively promote scleral collagen synthesis through electrical signals, achieving a paradigm shift from “passive support”to “active reinforcement”. Clinical outcomes indicate advantages in regulating axial length, enhancing visual function and blood circulation, and facilitating early intervention in children. Combined procedures with ICL implantation, cataract surgery or vitrectomy provide comprehensive treatment regimens for individual patients with varied conditions. This article also analyzes long-term issues and core controversies including ectopic posterior staphyloma and reoperation, and prospects future research directions such as artificial intelligence assistance, translation of smart materials and full-cycle prevention and treatment systems, so as to provide references for clinical practice and scientific research.

Childhood bronchial asthma (hereinafter referred to as asthma) is frequently accompanied by comorbidities such as allergic rhinitis, eczema, allergic enteritis, tic disorders, and obesity. Based on the theory of "syndrome-based disease regulation", this paper proposes that dampness, heat, and phlegm constitute the common pathological basis of asthma comorbidities in children living in cold regions. Focusing on the remission stage of asthma, this paper proposes that treatment should emphasize dispersing and draining pathogenic factors, diffusing and unblocking sanjiao (三焦), with clearing heat, draining dampness, and resolving phlegm as the fundamental therapeutic principle. For asthma complicated by allergic rhinitis, Xiebai Wendan Decoction (泻白温胆汤) combined with Cang'erzi Powder (苍耳子散) is recommended. For asthma complicated by eczema, Baiguo Wendan Decoction (白果温胆汤) combined with Yiyi Zhuye Powder (薏苡竹叶散) is applied. For asthma complicated by allergic enteritis, Zhizhu Wendan Decoction (枳术温胆汤) is selected. For asthma complicated by tic disorders, Changyu Wendan Decoction (菖郁温胆汤) is used. And for asthma complicated by obesity, Zexie Wendan Decoction (泽泻温胆汤) is prescribed. This approach aims to achieve the therapeutic goals of "treating different diseases with the same principle" and "regulating both constitution and disease".

Retinal vein occlusion(RVO), the second most common retinal vascular disease, is primarily caused by thrombosis or mechanical compression from adjacent arteries, leading to partial or complete venous obstruction. Emerging evidence suggests that inflammation plays a pivotal role in the pathogenesis of RVO. Various systemic inflammatory markers, such as NLR, SII, and PLR, have gained increasing attention due to their close association with the occurrence and clinical outcomes of RVO and secondary macular edema. Given their accessibility, low cost, and high reproducibility, these markers can serve as valuable adjuncts to ophthalmic imaging in assessing systemic inflammatory status and disease progression. This review systematically summarizes recent advances in systemic inflammatory markers for RVO, highlighting their associations with the occurrence, prognosis, and treatment response of RVO and macular edema. Furthermore, the limitations of current evidence were evaluated and outline future research directions were discussed, aiming to provide hematological adjunctive evidence for early risk identification and treatment monitoring in RVO.

Objective :
To investigate the expression and biological function of circular RNA(circRNA) hsa_circ_0002938 in gastric cancer.
Methods :
45 pairs of tumor tissues and para-cancerous tissues from gastric cancer patients who underwent tumor reduction surgery at the hospital were collected. Human gastric cancer cells SGC-7901, BGC-823, HGC-27, MGC-803 and immortalized gastric mucosal epithelial cells GES-1 were routinely cultured. RT-qPCR was utilized to detect the expression of hsa_circ_0002938 in gastric cancer tissues and cells. Chi-square test was used to analyze its association with the clinicopathological characteristics of patients, and the Kaplan-Meier method was employed to assess the relationship between hsa_circ_0002938 expression levels and patient prognosis. The effects of hsa_circ_0002938 on the proliferation, migration and invasion abilities of gastric cancer cells were detected by CCK-8, scratch wound healing and Transwell assays. Bioinformatics was used to predict the miRNA and its downstream target genes that hsa_circ_0002938 might bind to. The competitive endogenous RNA regulatory network was constructed and the functions of the target genes were enriched.
Results :
The expression of hsa_circ_0002938 in gastric cancer tissues and cells was much higher than that in para-cancerous tissues and GES-1 cells(P<0.05). By contrast, patients in the high hsa_circ_0002938 expression group had significantly shorter 2-year progression-free survival than that in the low expression group after surgery(P<0.01). Moreover, knocking down the expression of hsa_circ_0002938 reduced the proliferative, migratory, and invasive abilities of gastric cancer cells(P<0.05). Bioinformatics predictive analysis showed that hsa_circ_0002938 could bind to hsa-miR-342-3p and hsa-miR-503-5p. The downstream target genes of miRNA were involved in several cancer-related pathways, like mitogen-activated protein kinase(MAPK), hippo and Wnt signaling pathway.
Conclusion
Hsa_circ_0002938, which is highly expressed in gastric cancer tissues and cells, is closely associated with poor patient prognosis. Knockdown of hsa_circ_0002938 inhibits the proliferation, migration, and invasion abilities of gastric cancer cells. The study reveals the potential role of hsa_circ_0002938 in the progression of gastric cancer, offering new insights into its prevention and treatment.

OBJECTIVE To evaluate the efficacy, safety and cost-effectiveness of toripalimab (Tor) combined with chemotherapy (CT) in the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC). METHODS PubMed, the Cochrane Library, Embase, Web of Science, CBM, CNKI, Wanfang Data, and Health Technology Assessment (HTA) related websites were searched to collect the HTA reports, systematic reviews/meta-analyses and pharmacoeconomic studies of Tor+CT in the treatment of locally advanced or metastatic NSCLC from database/website inception to March 31, 2025. After data extraction and quality evaluation, the results of the included studies were analyzed descriptively. RESULTS A total of eleven studies were included, involving five systematic reviews/meta-analyses, and six pharmacoeconomic studies. Among the five systematic reviews/ meta-analyses, two were of high quality, while there was one each of moderate, low, and very low quality. All six pharmacoeconomic studies were of good quality. In terms of efficacy, compared with CT, Tor+CT significantly improved patients’ progression-free survival (PFS) and overall survival (P<0.05). In addition, compared with ipilimumab+CT, durvalumab, durvalumab+tremelimumab and sugemalimab+CT, Tor+CT could also improve the PFS (P<0.05). In terms of safety, there was no significant difference in the incidence of grade≥3 adverse events between patients receiving Tor+CT and CT (P>0.05); while Tor+CT had a lower incidence of grade≥3 adverse E-mail: events, compared with camrelizumab+CT, pembrolizumab+ 3233255290@qq.com ipilimumab, nivolumab+CT and atezolizumab+CT (P<0.05).In terms of cost-effectiveness, Tor+CT treatment had certain cost-effectiveness advantages, compared with CT. CONCLUSIONS Compared with CT, other programmed death-1/programmed death-ligand 1 inhibitors alone, or their combination with CT, Tor+CT for the treatment of locally advanced or metastatic NSCLC has good efficacy, safety and cost-effectiveness.

Soil cadmium pollution can adversely affect the cultivation of the ornamental plant, Coleus scutellarioides. Upon cadmium contamination of the soil, the growth of C. scutellarioides is impeded, and it may even succumb to the toxic accumulation of cadmium. In this study, we investigated the effects of arbuscular mycorrhizal fungi (AMF) on the adaptation of C. scutellarioides to cadmium stress, by measuring the physiological metabolism and the degree of root damage of C. scutellarioides, with Aspergillus oryzae as the test fungi. The results indicated that cadmium stress increased the activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and the content of malondialdehyde (MDA) and proline (Pro) within the cells of C. scutellarioides, but inhibited mycorrhizal infestation rate, root vigour and growth rate to a great degree. With the same cadmium concentration, the inoculation of AMF significantly improved the physiological indexes of C. scutellarioides. The maximum decrease of MDA content was 42.16%, and the content of secondary metabolites rosemarinic acid and anthocyanosides could be increased by up to 27.43% and 25.72%, respectively. Meanwhile, the increase of root vigour was as high as 35.35%, and the DNA damage of the root system was obviously repaired. In conclusion, the inoculation of AMF can promote the accumulation of secondary metabolites, alleviate root damage, and enhance the tolerance to cadmium stress in C. scutellarioides.

Chinese Journal of Biologicals 2025;38(12):1490-1497
Objective To establish an 8-hydroxyquinoline pre-column derivatization-high performance liquid chromatographydiode array detection(HPLC-DAD) method for the determination of aluminum content in vaccines, and to verify the method for vaccine quality control.Methods The determination was carried out by pre-column derivatization with 8-hydroxyquinoline, and the sample pretreatment conditions of hydrochloric acid solution concentration(0. 1, 0. 5, 1, 2, 5 mol/L),hydrochloric acid digestion time(20, 30, 40, 50, 60 min), concentratio%n of derivatization reagent 8-hydroxyquinoline(0. 5,1, 2, 3, 4 mg/mL), and ammonia concentration(1. 25%, 6. 25%, 12. 50%, 18. 75%, 25%) were optimized. ZORBAX SB-C_8(4. 6 mm × 150 mm, 5 ??m) column was used with methanol-water as mobile phase in gradient elution at a flow rate of0. 8 mL/min. The detection wavelength was 254 nm, the column temperature was 30 ℃, and the injection volume was 10 ??L.The linear range, accuracy, precision, specificity and stability of the method were validated, the limit of detection(LOD) and limit of quantification(LOQ) were determined, and the method was used to detect the aluminum content in 16 batches of bivalent human papillomavirus(HPV) and three batches of recombinant hepatitis E virus(HEV) vaccines.Results The optimized pretreatment conditions were as follows: hydrochloric acid concentration 1 mol/L, digestion time 20 min,derivatization reagent 8-hydroxyquinoline concentration 2 mg/mL, and ammonia concentration 12. 5%. Aluminum showed a good linearity in the concentration range of 2 to 100 ??g/mL, with a correlation coefficient(r) of 0. 999 98. The average recovery rates of spiked samples were between 89. 6% and 95. 7%. The relative standard deviation(RSD) of the aluminum content test results of six samples was 1. 4%. The blank reagent showed no interference with the detection. The sample solution exhibited good stability at room temperature for 12 h. The LOD and LOQ of the method were 0. 267 ??g/mL and0. 820 ??g/mL respectively. The established method was used to detect the aluminum content in 16 batches of HPV vaccines and three batches of recombinant HEV vaccines, and the results were not significantly different from those detected by titration method in General Principles 3106 of the Chinese Pharmacopoeia(Volume Ⅲ, 2020 edition).Conclusion The established HPLC-DAD method is accurate and reliable, with good precision, specificity and stability. The mobile phase is only methanol-water without adding buffer salts and derivatizing agents, etc., and it is easy to operate and friendly to instruments and chromatographic columns. The method requires a small amount of samples, which can realize the detection of a single dose of vaccine sample and provide reference for the quality control of vaccines.

AIM:To investigate whether casein kinase 2(CK2)/calmodulin(CaM)/small-conductance Ca2+-activated K+channel type 2(SK2)signaling pathway mediates autophagy-induced sympathoexcitation in the paraventricu-lar nucleus(PVN)of rats with chronic heart failure(CHF).METHODS:We randomly divided 180 Wistar rats,aged 6 to 8 weeks,into 10 groups:sham+dimethyl sulfoxide(DMSO),sham+artificial cerebrospinal(aCSF),CHF+DMSO,CHF+aCSF,CHF+rapamycin(RAPA),CHF+3-methyladenine(3-MA),CHF+5,6-dichlorobenzimidazole riboside(DRB),CHF+calmidazolium chloride(CMDZ),CHF+N-cyclohexyl-N-[2-(3,5-dimethyl-1H-pyrazol-1-yl)-6-methyl-pyrimidin-4-yl]-amine(CyPPA),and CHF+apamin groups.We measured cardiac function,hemodynamic parameters,anatomic indicators,and sympathetic drive indicators(n=18).Western blot was used to examine the protein levels of mi-crotubule-associated protein 1 light chain 3-II(LC3-II)/LC3-I,beclin-1,P62,CK2α,SK2,and phosphorylated CaM.The number of SK2-positive neurons was measured using immunofluorescence staining.The NG108 cells were randomly divided into 6 groups:DMSO,aCSF,RAPA,3-MA,RAPA+DRB,and RAPA+CMDZ groups.Radioisotope 32P-ATP pro-tein kinase activity assays were used to detect CK2 activity in cultured NG108 cells.We used Western blot to examine the protein levels of CK2α,SK2,and phosphorylated CaM.RESULTS:Compared with CHF rats treated with vehicle,CHF rats treated with RAPA or apamin exhibited increased sympathetic drive indicators,but decreased left ventricular ejection fraction and fractional shortening(P<0.01).However,CHF symptoms,including sympathoexcitation,were attenuated by 3-MA,DRB,CMDZ or CyPPA infusion into the PVN(P<0.01).In CHF rats,RAPA infusion into the PVN induced CK2 activity,up-regulated LC3-II/LC3-I,beclin-1,CK2α,and phosphorylated CaM levels,but down-regulated P62 and SK2 expression,as well as the number of SK2-positive neurons(P<0.05 or P<0.01).In CHF rats,infusion of 3-MA or DRB into the PVN decreased CK2 activity,and down-regulated phosphorylated CaM level(P<0.01).Infusion of 3-MA,DRB or CMDZ into the PVN up-regulated SK2 expression and the number of SK2-positive neurons(P<0.01).In cultured NG108 cells,RAPA induced CK2 activation and up-regulated the expression of CK2α and the phosphorylation of CaM,but down-regulated SK2 expression(P<0.01).Treatment with RAPA increased the level of phosphorylated CaM and down-regulated SK2 expression in cultured NG108 cells(P<0.01),which was inhibited by DRB and CMDZ(P<0.05 or P<0.01).CONCLUSION:In rats with CHF,the CK2/CaM/SK2 signaling pathway in the PVN contributes to autophagy-induced sympathoexcitation.
