With the advent of the refractive era of cataract surgery, postoperative residual refractive error has become a key factor affecting visual quality. The accuracy of intraocular lens(IOL)power calculation is affected by multiple factors, including ocular biological parameters, calculation formulas, and lens constants. Currently, the lens constants widely used in clinical practice are mostly based on Western populations, which have a mismatch with the ocular characteristics of the Chinese population, such as shorter axial length and steeper cornea. Therefore, the personalized optimization of the constant has become a research hotspot. This review primarily summarizes the research progress on lens constant optimization in improving the accuracy of IOL power calculation. Currently, there is no consensus on lens constant optimization methods. Single-constant formulas can be optimized through iterative methods, while multi-constant formulas require the combination of linear or nonlinear strategies. Simplified gradient descent and data-driven techniques offer new optimization pathways, but cross-validation is needed to evaluate their performance. Segmented optimization based on axial length, corneal curvature, and anterior chamber depth has shown significant effectiveness in patients with special anatomical structures, effectively reducing postoperative refractive errors in different patient groups, but limitations remain in some extreme cases. The interaction of multiple parameters significantly impacts the predictive accuracy of complex cases. While new-generation formulas integrating multiple parameters or incorporating AI algorithms have improved accuracy, constant optimization still holds value. Currently, the complex relationships between multiple parameters and intraoperative dynamic changes require further in-depth research. Future research, including targeted population optimization studies, the development of real-time monitoring technologies, and innovative IOL designs, may make achieving zero postoperative refractive error a possibility.

Salvia miltiorrhiza (Danshen) is a traditional Chinese herb that is commonly known for its cardiovascular and hepatoprotective benefits. Recent studies have confirmed that Danshen and its bioactive components can influence gut microbial homeostasis, thereby affecting Helicobacter pylori (HP) colonization in the human stomach. HP is a bacterial pathogen associated with various gastrointestinal diseases. Current HP treatments mainly involve antibiotics and proton pump inhibitors. However, their efficacy is strongly compromised by the rapid emergence of antibiotic resistance in HP and genetic heterogeneity among patients. The interaction between Danshen and gut microbial status provides a novel perspective for HP treatment. Understanding the medical properties of Danshen in altering gut microbiota and eliminating HP, as well as the underlying mechanisms, is important for improving human gastrointestinal healthcare. This review investigates the interaction between Danshen and gut microbiota and its impact on HP infection using databases including Web of Science, PubMed, and Google Scholar. We explored the unconventional intersection between Danshen, gut microbiota, and HP infection, shedding light on their intricate interplay and potential therapeutic implications. A comprehensive understanding of this interaction provides valuable insights into developing novel therapeutic strategies that target the gut microbiota to mitigate HP-associated gastrointestinal disorders.

OBJECTIVE:
Human brucellosis is a serious public health concern in the Xilingol League, Inner Mongolia; however, the epidemic trends are unclear.
METHOD:
In this study, Joinpoint regression analysis and spatiotemporal analysis were applied to investigate the epidemic evolution of human brucellosis.
RESULT:
From 2004 to 2023, a total of 35,747 cases were reported, with an annual average of 1787.35 cases and an annual average incidence rate of 176.04/100,000. The incidence increased from 173.96/100,000 in 2004 to 500.71/100,000 in 2009 and fluctuated to 61.43/100,000 in 2023. Three epidemic join points were observed in which the disease experienced an alternative rise and fall, peaking in 2009 (APC = 21.73, P > 0.001) and 2020 (APC = 21.51, P > 0.001). The disease showed a persistent decline trend in lentitude (AAPC = -5.30, P > 0.001), suggesting challenges in disease control and a higher risk of rebound. The most cases were reported in Xilinhot City ( n = 4,777), followed by 4,391 in Sonid Left Banner, and 4,324 in Abaga Banner. Spatiotemporal analysis revealed two high clusters (CI and CII) from 2005 to 2012, the high cluster encompassing eight counties and shifting from north to south.
CONCLUSION
The present analysis highlights that human brucellosis has decreased significantly in the Xilingol League, but the epidemic is still severe; further implementation of a strict control program is necessary.

Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective:Dehydrated hereditary stomatocytosis (DHS), a rare condition caused by pathogenic PIEZO1 or KCNN4 mutations, remains under-recognized. This study aimed to improve the diagnosis and management of DHS in China by retrospectively analyzing clinical and genetic characteristics.Methods:Patients diagnosed with DHS at Peking Union Medical College Hospital between 2018 and 2024 were included. All had suspected congenital hemolytic anemia and were confirmed by next-generation sequencing to harbor pathogenic PIEZO1 or KCNN4 mutations. Clinical features, genotypes, iron overload, and treatment outcomes were collected and analyzed.Results:Twenty-three DHS patients were identified, including 21 with PIEZO1 and 2 with KCNN4 mutations. Common manifestations were splenomegaly, jaundice, cholelithiasis, and secondary iron overload. Mild and moderate anemia occurred in 8.7% and 17.4% of patients, respectively, and stomatocytes were present in only 17.4%. The median time from symptom onset to diagnosis was 11 years. The predominant PIEZO1 variants were c.7367G > A and c.6328C > T, with nine novel mutations identified. Both KCNN4 mutations involved c.1055G > A. No clear genotype–phenotype correlation was observed. Secondary hepatic iron overload was found in 21.7% of patients.Conclusion:DHS is often underdiagnosed or misdiagnosed. Genetic testing enables accurate identification, and regular monitoring for secondary hepatic iron overload is crucial for long-term management.

Peptide receptor radionuclide therapy (PRRT) with radiolabeled SSTR2 agonists is a treatment option that is highly effective in controlling metastatic and progressive neuroendocrine tumors (NETs). Previous studies have shown that an SSTR2 agonist combined with albumin binding moiety Evans blue (denoted as 177Lu-EB-TATE) is characterized by a higher tumor uptake and residence time in preclinical models and in patients with metastatic NETs. This study aimed to enhance the in vivo stability, pharmacokinetics, and pharmacodynamics of 177Lu-EB-TATE by replacing the maleimide-thiol group with a polyethylene glycol chain, resulting in a novel EB conjugated SSTR2-targeting radiopharmaceutical, 177Lu-LNC1010, for PRRT. In preclinical studies, 177Lu-LNC1010 exhibited good stability and SSTR2-binding affinity in AR42J tumor cells and enhanced uptake and prolonged retention in AR42J tumor xenografts. Thereafter, we presented the first-in-human dose escalation study of 177Lu-LNC1010 in patients with advanced/metastatic NETs. 177Lu-LNC1010 was well-tolerated by all patients, with minor adverse effects, and exhibited significant uptake and prolonged retention in tumor lesions, with higher tumor radiation doses than those of 177Lu-EB-TATE. Preliminary PRRT efficacy results showed an 83% disease control rate and a 42% overall response rate after two 177Lu-LNC1010 treatment cycles. These encouraging findings warrant further investigations through multicenter, prospective, and randomized controlled trials.

Objective Methyltransferase 3(METTL3)mediated N6-methyladenosine(m6A)methylation modifica-tion of transient receptor potential cation channel subfamily M member 7(TRPM7)regulates ferroptosis and malig-nant progression in cervical cancer(CESC).Methods Totally 40 patients with cervical cancer were collected.Cer-vical cancer tissues and adjacent normal tissues(≥3 cm from the edge of the tumor tissue)were sampled at opera-tion and then divided into experimental group and control group,respectively.RT-qPCR and Western blot were used to detect the differences in TRPM7 mRNA and protein expression between the two groups.TRPM7-interfering cell lines were constructed to investigate the effects of TRPM7 on CESC cells.Cell proliferation and apoptosis were assessed using 5-ethynyl-2'-deoxyuridine(EdU)assay and flow cytometry,respectively.Transwell chamber assays were employed to evaluate cell invasion and migration capabilities.The levels of ferroptosis in CESC cells were measured using kits for reactive oxygen species(ROS),malondialdehyde(MDA),glutathione(GSH),and Fe2+.Bioinformatics tools were utilized to predict methyltransferases associated with TRPM7.The interaction between METTL3 and TRPM7 was examined through RNA immunoprecipitation(RIP)and methylated RNA immunoprecip-itation quantitative PCR(Me-RIP qPCR).The effect of METTL3 on the stability of TRPM7 expression was assessed using actinomycin D assay.Results TRPM7 was highly expressed in CESC tissue and cells.Knockdown of TRPM7 significantly inhibited cell proliferation,promoted cell apoptosis,suppressed cell migration and invasion capabilities,and enhanced ferroptosis levels(P<0.05).Bioinformatics predictions suggested that METTL3 might act as a methyltransferase for TRPM7.Interference with METTL3 gene expression significantly reduced TRPM7 pro-tein levels,decreased TRPM7 m6A modification levels,and impaired TRPM7 gene stability(P<0.05).Conclusions METTL3 regulates CESC proliferation,apoptosis,migration,invasion,and ferroptosis by m6A meth-ylation modification of the TRPM7 gene.

Objective: To investigate the protective effects and underlying mechanisms of sodium pyruvate (SP) on RBC storage lesions using an oxidative damage model. Methods: Six units of leukocyte-depleted suspended RBCs (discarded for non-infectious reasons within three days post-collection) were randomly assigned to four groups: negative control (NS), positive control (PS), experimental group 1 (SP1), and experimental group 2 (SP2). Oxidative stress was induced in the PS group by the addition of hydrogen peroxide (H
O
), while SP1 and SP2 received SP supplementation at different concentrations (25 mM and 50 mM, respectively) in the presence of H
O
. After 1 hour of incubation, RBC morphology was assessed microscopically, and biochemical indicators including glutathione (GSH), malondialdehyde (MDA), methemoglobin (MetHb), adenosine triphosphate (ATP), and Na
/K
-ATPase activity were measured. Results: RBCs in the PS group exhibited pronounced morphological damage, including cell shrinkage and echinocyte formation, whereas both SP-treated groups showed significantly reduced structural injury. SP treatment led to elevated GSH levels and decreased concentrations of MDA and MetHb, suggesting attenuation of oxidative stress. Additionally, SP enhanced intracellular ATP levels and Na
/K
-ATPase activity, thereby contributing to membrane stability. Notably, the SP2 group (50 mM) demonstrated superior protective effects compared to SP1 (25 mM). Conclusion: Sodium pyruvate effectively attenuates oxidative storage lesions in RBCs, primarily through its antioxidant properties, energy metabolism supporting ability, and celluar membrane stabilizing function. These findings suggest SP as a promising additive for enhancing the quality and safety of stored RBCs.

Objective:
To assess the dynamic changes of microcirculation at acupoints in patients with primary dysmenorrhea and cold congelation and blood stasis syndrome using laser speckle blood flow imaging.
Methods:
Patients with primary dysmenorrhea and cold coagulation and blood stasis syndrome (primary dysmenorrhea group, n=53) and healthy female college students(control group, n=57) who met the inclusion and exclusion criteria from October 2020 to July 2022 were enrolled at Hebei University of Chinese Medicine. On the premenstrual and first day of menstruation, a laser speckle blood flow imaging system was used to measure the microcirculation blood flow perfusion on the surface of acupoints related to the conception, thoroughfare, and governor vessels, and stomach, spleen, and bladder meridians in the abdomen and lumbosacral regions. The dynamic changes in microcirculation were calculated based on the difference in average blood flow perfusion at each acupoint before and after menstruation. Receiver operating curve (ROC) analysis was used to analyze the diagnostic efficacy of dynamic changes in microcirculation on the surface of each acupoint. The microcirculation sensitization rate of acupoints was calculated.
Results:
Compared with the control group, the dynamic changes in microcirculation at the following acupoints in the primary dysmenorrhea group were increased (P<0.05): conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]); left thoroughfare vessel (left Huangshu[KI16], left Zhongzhu[KI15], left Siman[KI14], left Qixue[KI13], left Dahe[KI12], left Henggu[KI11]); left stomach meridian (left Tianshu[ST25], left Wailing[ST26], left Qichong[ST30]); left spleen meridian (left Daheng[SP15], left Fujie[SP14]); right thoroughfare vessel (right Huangshu[KI16], right Zhongzhu[KI15], right Siman[KI14], right Qixue[KI13], right Dahe[KI12], right Henggu[KI11]); right stomach meridian (right Wailing[ST26], right Daju[ST27], right Shuidao[ST28], right Guilai[ST29], right Qichong[ST30]); and right spleen meridian (right Fujie[SP14]). The area under the ROC curve of conception vessel (Yinjiao[CV7], Qihai[CV6], Shimen[CV5], Guanyuan[CV4]), thoroughfare vessel (right Siman[KI14], left Huangshu[KI16], right Qixue[KI13], right Zhongzhu[KI15], right Dahe[KI12], left Zhongzhu[KI15], left Siman[KI14], right Huangshu[KI16], left Qixue[KI13], right Henggu[KI11], left Henggu[KI11], left Dahe[KI12]); stomach meridian (left Tianshu[ST25], right Guilai[ST29], left Wailing[ST26], right Shuidao[ST28], right Daju[ST27], right Wailing[ST26], right Qichong[ST30], left Qichong[ST30]), and spleen meridian (left Daheng[SP15], left Fujie[SP14], right Fujie[SP14]) was 0.610-0.682 (P<0.05). Compared with the control group, the sensitization rate of some acupoints in the primary dysmenorrhea group increased (P<0.05).
Conclusion
With the onset of menstruation, the blood flow perfusion of some acupoints in the abdomen (thoroughfare, and conception vessels, and stomach and spleen meridians) of patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome increased, and the status of acupoints changed from a resting state to an active state. These acupoints are sensitive in patients with primary dysmenorrhea and cold blood coagulation and blood stasis syndrome and have a certain diagnostic efficacy, providing a basis for further analyzing the efficacy and mechanism of acupuncture and moxibustion to treat primary dysmenorrhea with cold blood coagulation and blood stasis syndrome.

Aim To evaluate the tyrosine nitration modification of specific proteins in vascular endothelial cells and its impact on mitochondria-mediated apoptosis.Methods Human umbilical vein endothelial cells were cultured in vitro and divided into three groups:control group(treatment with dimethyl sulfoxide),3-morphansulam(SIN-1)group,and SIN-1+Fe(Ⅲ)5,10,15,20-(tetraphenyl)porphyrin(FeTPP)group.After 24 h,the levels of hexokinase 1(HK1)nitration modification,mitochondrial membrane potential,reactive oxygen species(ROS)production,and endothelial cell proliferation and apoptosis were assessed.A human umbilical vein endothelial cell line knockout of HK1 was constructed using gene editing technology,and its proliferation and apoptosis levels were detected.Results After treatment of hu-man umbilical vein endothelial cells with peroxynitrite generator SIN-1,the level of HK1 protein nitration modification sig-nificantly increased(P<0.01),reactive oxygen species production significantly increased,mitochondrial membrane poten-tial significantly decreased,endothelial cell proliferation ability significantly decreased,and endothelial cell apoptosis level significantly increased(all P<0.01).Peroxynitrite decomposition catalyst FeTPP could reverse the above effect(P<0.01).In addition,HK1 gene knockout also exhibited similar antioxidant effects,with a significant decrease in endothe-lial cell proliferation ability and a significant increase in apoptosis levels(P<0.01).Conclusion Peroxynitrite can induce an increase in the level of nitration modification of HK1 in vascular endothelial cells,which may be achieved by pro-moting the production of mitochondrial reactive oxygen species,thereby accelerating the process of endothelial cell apoptosis.
