Abstract In April 2021, type Ⅰ vaccine-derived poliovirus (VDPV) was detected from two fecal samples of a male infant with acute flaccid paralysis (AFP) in Zhejiang Province when he was admitted to the Children's Hospital Affiliated to Fudan University in Shanghai, with 12 and 14 nucleotide mutations in the VP1 region, respectively. The case had a history of immunization with three doses of poliovirus vaccines, and grade Ⅲ proximal muscle strength and grade Ⅱ distal muscle strength of the right lower limb. After symptomatic treatment, the activity of the right lower limb and the muscle strength was significantly restored, thus he was discharged. VDPV was not detected from subsequent (the 8th to 12th) fecal samples of the case and fecal samples of close contacts. No similar cases were found in medical institutions in the county, surrounding areas, neighboring villages or towns. Since the case did not exhibit clinical symptoms of poliomyelitis caused by VDPV, poliomyelitis was excluded, and the case was diagnosed with hemophilia type A based on the epidemiological investigation, laboratory tests, and the history of poliomyelitis vaccination. This event involved cross-provincial (municipal) cooperation and was responsed promptly, preventing further spread of the virus. It suggested that the sensitivity of the AFP case surveillance system should be maintained, environmental monitoring methods should be increased, and the poliomyelitis vaccination should be promoted to prevent the spread of the virus.

Myopia is a common eye disease among children and adolescents, and it is also a major and common public health problem for children and adolescents worldwide. Although the myopia rate among children and adolescents in different provinces , cities , and regions varies , the incidence of myopia is generally high , showing a trend of high incidence and younger age. Myopia in children and adolescents is closely related to sleep conditions . The sleep time of most children and adolescents in China does not reach the recommended length of time for this age group, and their sleep quality is poor, which affects their study and life. The biological connection and molecular mechanism between sleep and myopia are hot topics in clinical research . This article reviews the epidemiological characteristics of myopia and sleep status in children and adolescents , as well as the biological mechanisms between sleep and myopia , with the aim of providing a theoretical basis for preventing myopia in children and adolescents.

ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

AIM: To analyze the prevalence, severity, types, and correction of astigmatism in children, and provide scientific evidences for the prevention and treatment of refractive errors.METHODS: This cross-sectional study included 29 153 children aged 6-12 years from Xi'an and Lantian County, Shaanxi Province, China. Visual acuity and non-cycloplegic refraction were measured. Astigmatism was defined as an absolute cylindrical power ≥0.5 D in the right eye. Differences in astigmatism severity, type distribution, and refractive correction were analyzed across age, gender, and region.RESULTS:The prevalence of astigmatism increased with age, peaking at 11 years old(62.88%). Boys(57.10%)had a higher prevalence than girls(54.86%), and the municipal areas(58.29%)had a higher prevalence than county areas(51.75%). Mild astigmatism was the most common(63.82%), with moderate astigmatism increasing with age. The highest prevalence of high astigmatism was observed in 11-years-old children(9.68%). Compound myopic astigmatism(59.28%)and mixed astigmatism(25.16%)were the most frequent types. With increasing age, compound myopic astigmatism increased, while simple myopic, simple hyperopic, and compound hyperopic astigmatism decreased. Mixed astigmatism increased from ages 6 to 7, but declined from ages 7 to 12. For astigmatic axis types, with-the-rule astigmatism was the most prevalent(81.06%)and increased with age, peaking at 11 years(85.74%). Against-the-rule astigmatism showed a declining trend, while oblique astigmatism remained relatively stable. Distribution differences in astigmatism types and axes by gender and region were observed. Significant differences in astigmatism severity, types, and axis types across different ages, genders, and regions were observed(all P<0.05). The overall refractive correction rate for children with astigmatism was only 40.18%.CONCLUSION: The overall prevalence of astigmatism among children aged 6-12 years in Shaanxi Province was 56.02%, with higher prevalence observed in boys and in municipal areas. Age, gender, and region significantly influenced the prevalence of astigmatism. Notably, less than half of the children with astigmatism received refractive correction, highlighting the need for increased attention from parents and relevant authorities.

Objective: o develop an onset risk prediction nomogram for patients with homocysteine-type (H-type) hypertension (HTH) based on pulse diagram parameters to assist early clinical prediction and diagnosis of HTH. Methods: Patients diagnosed with essential hypertension and admitted to Shanghai Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai Hospital of Traditional Chinese Medicine, and Shanghai Hospital of Integrated Traditional Chinese and Western Medicine from July 6th 2020 to June 16th 2021, and from August 11th 2023 to January 22nd 2024, were enrolled in this retrospective research. The baselines and clinical biochemical indicators of patients were collected. The SMART-I TCM pulse instrument was applied to gather pulse diagram parameters. Multivariate logistic regression was adopted to analyze the risk factors for HTH. RStudio was employed to construct the nomogram model, receiver operating characteristic (ROC) curve, and calibration curve (bootstrap self-sampling 200 times), and clinical decision curve were drawn to evaluate the model’s discrimination and clinical effectiveness. Results: A total of 168 hospitalized patients with essential hypertension were selected and divided into non-HTH group (n = 29) and HTH group (n = 139). Compared with non-HTH group, HTH group had a lower body mass index (BMI), and higher proportions of male patients and drinkers (P < 0.05). The ventricular wall thickening (VWT) could not be determined. The proportions of left common carotid intima-media wall thickness (LCCIMWT) and serum creatinine (SCR) were higher in HTH group (P < 0.05). The pulse diagram parameter As was significantly higher, and H4/H1 and T1/T were lower in HTH group (P < 0.05). Gender, alcohol consumption, serum creatinine, and the pulse diagram parameter H4/H1 were identified as independent risk factors for HTH (P < 0.05). The nomogram’s area under the ROC curve (AUC) was 0.795 [95% confidence interval (CI): (0.706 6, 0.882 8)], with a specificity of 0.724 and sensitivity of 0.799. After 200 times repeated bootstrap self-samplings, the calibration curve showed that the simulated curve fits well with the actual curve (x2 = 9.5002, P = 0.301 9). The clinical decision curve indicated that the nomogram’s applicability was optimal when the threshold for predicting HTH was between 0.38 and 1.00. Conclusion The nomogram model could be valuable for predicting the onset risk of HTH and pulse diagram parameters can facilitate early screening and prevention of HTH.

OBJECTIVE To provide a reference for standardizing the conduct of positron-emitting radiopharmaceuticals’ phase 0 clinical trials （hereinafter referred to as “phase 0 clinical trials”） and advancing the development of innovative drug by medical institutions. METHODS Initiated by the First Affiliated Hospital of Jinan University， a panel of experts consisting of pharmacy， clinical medicine and medical ethics from multiple institutions was established to investigate the current landscape， and discuss the necessary conditions， procedures， and other aspects for conducting phase 0 clinical trials in medical institutions by integrating relevant national policies， regulations and expert consensus. Finally， an agreement was reached to formulate this consensus. RESULTS & CONCLUSIONS Currently， most medical institutions have deficiencies in pharmaceutical care during the management of radiopharmaceuticals and the phase 0 clinical trials. In conjunction with the Expert Consensus on the Establishment of Nuclear Pharmacist Positions， this consensus explicitly defines the responsibilities of nuclear pharmacists in the phase 0 clinical trials on the basis of the Expert Consensus for the Application of Positron Emission Tomography Radioligands for Translational Study in the Phase 0 Clinical Trials （2020 edition）， providing a guidance for high-quality participation of nuclear pharmacists from medical institutions in China in phase 0 clinical research. Additionally， in consideration of some constraints imposed by current relevant regulations， this consensus also proposes strategic recommendations， such as encouraging medical institutions to form a consortium， leading to the establishment of dedicated bases or industrial parks， holding significant implications to strengthen institutional capacity for advancing radiopharmaceutical innovation through phase 0 clinical trials.
