Objective To investigate the incidence trend of infectious diseases among kindergarten children in Yangpu District, Shanghai, and to provide scientific reference for prevention and control strategies of infectious diseases among key populations. Methods Descriptive epidemiology method and Joinpoint regression analysis model were used to analyze the surveillance data of infectious diseases among kindergarten children. Results The average annual reported incidence of infectious diseases among kindergarten children in Yangpu District was 3,344.08/100,000, showing a downward trend (AAPC=-5.51, 95%CI: -13.02~2.63). Intestinal (65.49%) and respiratory (34.48%) infectious diseases were the main cases. There were 7,378 cases of hand, foot and mouth disease (62.95%), 1,885 cases of influenza (16.08%), 1,378 cases of varicella (11.76%), and 392 cases of mumps (3.34%), accounting for 94.14% of all reported cases. Hand, foot and mouth disease (AAPC=-17.68%, 95%CI: -27.52~-6.51), mumps (AAPC=-9.33, 95%CI: -14.86~-3.45) and varicella (AAPC=-7.32, 95%CI: -17.35~3.93) showed an overall decreasing trend, while influenza (AAPC=32.19, 95%CI: 12.49-55.34) was on the rise. The incidence of the disease showed double peak distribution, and the high incidence months were from May to July and from September to December. The male to female ratio was 1.39:1. Conclusion The incidence of infectious diseases among kindergarten children in Yangpu District shows a downward trend. It is necessary to continue to increase the coverage rate of Enterovirus 71(EV71), influenza, chickenpox and MMR combined live attenuated vaccine, strengthen monitoring and early warning, actively carry out health guidance, and effectively control the occurrence of common infectious diseases in kindergarten children.

Retinal microcirculatory disorder is a key factor in the occurrence and development of diabetic retinopathy （DR）， and also an important link in the prevention and treatment of DR. The theory of "Gaozhuo" holds that the microcirculatory disorder in DR is based on the deficiency of spleen Qi and is characterized by the obstruction caused by "Gaozhuo" and blood stasis. The deficiency of spleen Qi is an essential precondition for the endogenous formation and accumulation of Gaozhuo， while Gaozhuo invasion is the direct cause of microcirculatory disorders in DR. The deficiency of spleen Qi and the endogenous formation of Gaozhuo mean the process in which glucose metabolism dysfunction induces an excessive production of inflammatory factors and lipid metabolites. The obstruction caused by "Gaozhuo" and blood stasis is the direct pathogenesis of microcirculatory disorders in DR， encompassing two stages： Gaozhuo obstruction and turbidity and stasis stagnation. Gaozhuo obstruction and turbidity and stasis stagnation represent the process in which inflammatory factors and lipid metabolites damage the retinal microcirculation and induce thrombosis， thus mediating microcirculatory disorders. Turbidity and stasis stagnation and blood extravasation outside the vessels reveal the progression to microvascular rupture and hemorrhage resulting from the microcirculatory disorders. According to the pathogenesis evolution of the theory of "Gaozhuo"， microcirculatory disorders in DR can be divided into deficiency of spleen Qi with Gaozhuo obstruction， deficiency of spleen Qi with turbidity and stasis stagnation， and turbidity and stasis stagnation with blood extravasation outside the vessels. Clinically， treatment principles should focus on strengthening the spleen and benefiting Qi， resolving turbidity， and dispersing stasis. Different syndrome patterns should be addressed with tailored therapies， such as enhancing the spleen and benefiting Qi while regulating Qi and reducing turbidity， strengthening the spleen and benefiting Qi while resolving turbidity and dispelling stasis， and strengthening the spleen and resolving turbidity while removing stasis and stopping bleeding. Representative prescriptions include modified Wendantang， modified Buyang Huanwutang， modified Danggui Buxuetang， Zhuixue Mingmu decoction， Tangmuqing， Shengqing Jiangzhuo Tongluo Mingmu prescription， Danhong Huayu decoction， and Yiqi Yangyin Huoxue Lishui formula.

ObjectiveTo evaluate the clinical efficacy and safety of Jingmaiyan granules （composed of Lonicerae Japonicae Flos， Sedi Herba， Paeoniae Radix Rubra， Moutan Cortex， Rhei Radix et Rhizoma Praeparata， and Glycyrrhizae Radix et Rhizoma） combined with external application of Jinhuang Ointment in treating acute-stage blood heat stasis type superficial thrombophlebitis （ST） of lower extremities， and to explore their effects on hemorheology and serum inflammatory factors. MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 124 patients with lower extremity ST were randomized into two groups（62 cases in each group）. The control group received external application of Jinhuang ointment and oral placebo treatment， while the observation group received external application of Jinhuang ointment and oral Jingmaiyan granules. Both groups were treated for 2 weeks. The clinical symptom scores， therapeutic efficacy of traditional Chinese medicine （TCM） syndrome， pain visual analog scale （VAS） scores， hemorheological indices ［including whole blood high-shear， medium-shear， and low-shear viscosity， as well as plasma viscosity （PV）］， and inflammatory factors ［C-reactive protein （CRP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）］ were compared before and after treatment. ResultsAfter 2 weeks of treatment， the total effective rate in the observation group （98.3%， 60/62） was significantly higher than that in the control group （83.8%， 52/62）， with a statistically significant difference （Z=3.512 1， P<0.05）. Compared with pre-treatment scores， the scores for skin color， skin temperature， swelling， pain， and cord or nodules were significantly reduced in both groups （P<0.05）， with more pronounced improvement in the observation group （P<0.05）. Additionally， compared with pre-treatment levels， the whole blood viscosity （low-， medium-， and high-shear） significantly improved in both groups after treatment （P<0.05）， with more marked improvement in the observation group （P<0.05）. Furthermore， the plasma viscosity， CRP， IL-6， and TNF-α levels were significantly reduced in both groups after treatment （P<0.05）， with more pronounced improvement observed in the observation group （P<0.05）. ConclusionThe combination of external application of Jinhuang ointment and oral Jingmaiyan granules effectively improves clinical symptoms， hemorheological abnormalities， and inflammatory responses in patients with acute stage blood heat stasis type ST of lower extremities. The treatment is safe and holds clinical promotion value.

Background: and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes. Methods: This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics. Results: Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95). Conclusions Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

AIM: To investigate the relationship between serum levels of sirtuins(Sirts)1-6 and oxidative stress markers, and to evaluate their diagnostic value for age-related cataract(ARC).METHODS:A prospective cohort of ARC patients admitted to the hospital between June 2019 and July 2021 was enrolled as the study subjects. Concurrently, age-matched healthy individuals undergoing routine physical examinations at the hospital during the same period were recruited as the control group. Baseline demographic and clinical characteristics were compared between the two groups. Serum levels of Sirt1-6 and oxidative stress markers including malondialdehyde(MDA), superoxide dismutase(SOD), glutathione peroxidase(GSH-Px), and total antioxidant capacity(TAC)were compared. Pearson correlation analysis was performed to assess the associations between serum Sirt1-6 levels and oxidative stress parameters. Multivariate Logistic regression analysis was conducted to analysis risk factors associated with ARC occurrence. Receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of serum Sirt1-6 levels and oxidative stress indicators for ARC.RESULTS: The study included 127 ARC patients, comprising 68 men and 59 women, with a mean age of 66.05±2.58 y; the concurrent control group consisted of 121 patients, comprising 63 men and 58 women, with a mean age of 65.54±2.86 y. Serum levels of Sirt1, 3 and 6, SOD, GSH-Px, and TAC were significantly lower in the ARC group compared to the control group(all P<0.001), whereas MDA levels were markedly elevated(P<0.001). Pearson correlation analysis revealed that serum levels of Sirt1, Sirt3, Sirt6 in the ARC group were positively correlated with SOD, GSH-Px, and TAC, and negatively correlated with MDA. Multivariate Logistic regression analysis demonstrated that serum Sirt1, Sirt6, MDA, SOD, and GSH-Px were significantly associated with the occurrence of ARC(all P<0.001). ROC curve analysis showed that the combination of Sirt1, Sirt6, MDA, SOD, and GSH-Px yielded an area under the curve(AUC)of 0.995 for diagnosing ARC, which was significantly higher than that of Sirt1 alone(Z=4.978,P<0.001), Sirt6 alone(Z=7.487,P<0.001), MDA alone(Z=6.449,P<0.001), SOD alone(Z=5.773,P<0.001), or GSH-Px alone(Z=5.056,P<0.001), indicating superior diagnostic accuracy of the multimarker panel(P<0.05). CONCLUSION: Serum levels of Sirt1, 3, and 6 are generally reduced in ARC patients and are closely associated with oxidative stress imbalance. Specifically, decreased serum levels of Sirt1 and Sirt6, along with oxidative stress markers(elevated MDA and reduced SOD and GSH-Px)are identified as risk factors for ARC. Moreover, the combined detection of these indicators presents high diagnostic value for ARC.

As the largest microbial community in the human body,the intestinal microecology plays a pivotal role in the health and disease progression of the host.As part of the human symbiotic system,the metabolites of the intestinal microecology have a profound impact on the physiological and pathological states of the host.Hospi-tal-acquired infections(HAIs),as a common health problem among hospitalized patients,involve complex necha-nisms influenced by multiple factors.In recent years,with the advancement of technologies such as 16S rRNA and shotgun sequencing,researchers have gradually recognized that the intestinal microecology plays an important role in the occurrence and development of HAIs.In the intensive care unit,the treatment of primary diseases,sec-ondary infections,and the use of clinical treatment methods often lead to intestinal microecological imbalance.This article reviews the characteristics of changes in the intestinal microecology of critically ill patients after admission and explores the relationship between these changes and HAIs,aiming to deeply explore the possible mechanisms of the intestinal microorganisms in affecting the hospital-associated infections and provide theoretical support for developing prevention and treatment strategies.

Polycystic ovary syndrome(PCOS)is clinically characterized by insulin resistance,ovulatory dysfunction and hyperandrogenemia,often accompanied by obesity,type 2 diabetes,and dyslipidemia.This article reviews the recent studies on the intervention of PCOS with herbal medicines,including traditional Chinese medicine(TCM)compound formulas and single active compounds.The results demonstrate that both TCM compound formulas and single active compounds are effective on improving PCOS symptoms,with the advantages of multi-target actions and personalized treatment.TCM compound formulas for PCOS can be categorized into kidney-tonifying formulas(e.g.,Antai Fanglou Decoction,Gui Zhu Yikun Formula,Liuwei Dihuang Pills,Bushen Huayu Formula),phlegm-resolving formulas(e.g.,Cang Fu Daotan Decoction,Erchen Decoction),liver-soothing formulas(e.g.,Xiaoyao San,Shaoyao Gancao Decoction),and blood-activating formulas(e.g.,Jiawei Shaoyao Gancao Decoction,Gexia Zhuyu Decoction,Huayu Xiaozheng Decoction).These compound formulas separately exhibit actions of tonifying kidney essence,soothing liver and relieving depression,and activating blood circulation to resolve stasis,which are aligned with the TCM etiology and pathogenesis of PCOS.Single active compounds from herbal medicine primarily include flavonoids,alkaloids,terpenoids and polyphenols.Extractives from herbal medicines exert therapeutic effects by inhibiting ovarian inflammatory responses and relieveing hyperandrogenemia insulin resistance.Key signaling pathways for the intervention of PCOS with TCM include PI3K/AKT/mTOR,SIRT1/AMPK,TLR4/NF-κB,IRS1/PI3K/GLUT4,RIP1/RIP3/MLKL,HMGB1/RAGE,and Hippo-YAP.The review of recent advances in TCM formulas and single active compounds for the treatment of PCOS along with their underlying mechanisms will provide valuable insights for clinical management and new drug development for PCOS.

AIM: To investigate the effect of corneal topography-guided phacoemulsification with transparent corneal incision on cataract patients.METHODS:A total of 92 cataract patients(92 eyes)admitted to our hospital from February 2021 to February 2023 were prospectively selected and randomly divided into two groups: the control group(46 eyes)received the conventional 11:00 clear corneal incision scheme, and the study group(46 eyes)received the steepest meridian clear corneal incision scheme. The uncorrected visual acuity, corneal surface morphology indicators, including surface regularity index(SRI), surface asymmetry index(SAI), and cylinder(CYL), subjective dry eye symptoms questionnaire scoring scale(SDES), tear film break-up time(BUT), and complications were compared between the two groups.RESULTS:All patients completed the follow-up. The uncorrected visual acuity of the study group was significantly better than that of the control group at 1 wk, 1 and 3 mo after surgery(all P<0.05); there were statistical significance in the SAI and CYL of both groups of patients at 3 mo after surgery(all P<0.05); the fluctuation levels of SDES and BUT in the study group were significantly lower than those in the control group at different time points after surgery(all P<0.05); and there was no statistical difference in complications between the two groups(P>0.05).CONCLUSION:Under the guidance of corneal topography, phacoemulsification through the transparent corneal incision of the steepest meridian of the cornea can improve the uncorrected visual acuity of cataract patients, restore the corneal surface morphology, and have few complications.
