To summarize the clinical experience of Professor WANG Jie in treating palpitation using the method of tonifying the kidneys and invigorating blood. It is believed that kidney yang deficiency and heart vessel stasis are the key pathogenesis of palpitation， and it is advocated to treat palpitation by tonifying the kidney and invigorating the blood. Meanwhile，the methods of draining water， dissolving phlegm， and fortifying the spleen to supplement the blood should be applied. For palpitation with kidney yang deficiency and heart vessel stasis with upward water， the treatment could use self-prescribed Bushen Huoxue Lishui Formula （补肾活血利水方）； for palpitation with phlegm obstruction in blood vessel， the treatment could use self-prescribed Bushen Huoxue Huatan Formula （补肾活血化痰方）； for palpitation with spleen yang deficiency， the treatment could use self-prescribed Bushen Huoxue Jianpi Formula （补肾活血健脾方）.

Objective To investigate the the levels of magnesium,lead,iron,zinc,copper,manganese,calci-um in whole blood in children aged 0-12 years in Henan province,understand the health status of children and provide a basis for their nutrition and health management.Methods Data were collected from totally 135 385 children aged 0-12 years who underwent trace element testing at Zhengzhou Kingmed Clinical Labo-ratory Inc.from 2019 to 2023 were selected,and agilent inductively coupled plasma mass spectrometer was used to detect seven elements(magnesium,lead,iron,zinc,copper,manganese,and calcium).The elemental detection method in the laboratory has been strictly methodologically verified,and has participated in the ex-ternal quality assessment organized by National Center for Clinical Laboratories.Grouping was conducted based on gender,age,season,region,and year to compare the deficiencies and lead exceedances of six elements(magnesium,iron,zinc,copper,manganese,calcium)under different conditions.Results In this study,the mean P-values of seven elements in different age groups,gender groups,year groups,and regional groups were all＜0.001.Except for lead with a P-value of 0.002,all other elements in different season groups were＜0.001.The P-values were all less than 0.05,indicating statistically significant differences.Among them,Mag-nesium,iron,and zinc in children's whole blood showed an increasing trend with age,while copper,manga-nese,and calcium showed a decreasing trend with age.The proportions of children aged 0-1 years with iron,zinc,and manganese deficiencies were the highest,at 24.70％,48.20％,and 0.65％,respectively.The highest proportion of copper and calcium deficiency was in the age range of 11-12 years old,accounting for 20.43％and 0.17％respectively.The highest proportion of lead exceeding the standard was 0.87％among children aged 0-1.Except for manganese and calcium levels,the levels of the other five elements were higher in boys than in girls.Magnesium and copper levels were highest in spring,iron,zinc,and calcium levels were highest in winter,and manganese and lead levels were highest in summer.Magnesium deficiency,calcium deficiency,and lead excess were showing a decreasing trend year by year.Among them,the lead levels of children in Sanme-nxia and Jiyuan were relatively high compared to other areas.Conclusion 0-2 years children are mainly char-acterized by calcium and zinc deficiency in Henan province.Attention should be paid to iron and zinc supple-mentation in infants and young children.At the same time,it should also be noted that the deficiency rate of copper increases with age,and attention should be paid to the supplementation of copper in children.

Epilepsy is a chronic neurological disorder that often begins in childhood and can extend over the entire life course; therefore, it is necessary to establish a long-term, systematic life-course management model. Whole life-cycle disease management emphasizes interventions at key points in time and focuses on diagnosis and treatment points at all stages of life and disease processes. Guided by the concept of holism and preventive treatment, this article discussed the application strategies of TCM in the prevention, control, treatment, health and management of epilepsy in children at different stages. In the prevention period, the disease should be prevented first, and early screening should be carried out; in the control period, the disease should be prevented from changing, and the early intervention of Chinese materia medica should be carried out; during the treatment period, the combination of disease and syndrome and dynamic syndrome differentiation by stages were adopted; during the rehabilitation period, the treatment of different diseases with the same treatment should be emphasized to manage the comorbidity and improve the prognosis; in the long-term management period, the prevention and recovery after stroke should be focused on, and the comprehensive management scheme of TCM in the transition period from children to adults should be put forward. This article systematically expounded the role of TCM in improving seizure control rate and prognosis in the whole life-cycle management of childhood epilepsy, and actively explored the construction of the whole process health management system of chronic diseases.

Objective:To observe the efficacy and safety of vitrectomy combined with subretinal injection of alteplase (tPA) and intravitreal injection of Conbercept in the treatment of large area submacular hemorrhage (SMH) secondary to polypoidal choroidal vasculopathy (PCV).Methods:A retrospective clinical study. From January to September 2021, 32 eyes of 32 patients with massive SMH secondary to PCV diagnosed in the Affiliated Eye Hospital of Nanchang University were included in the study. Large SMH was defined as hemorrhage diameter ≥4 optic disc diameter (DD). There were 32 patients (32 eyes), 20 males and 12 females. The mean age was (72.36±8.62) years. All patients had unilateral disease.The duration from onset of symptoms to treatment was (7.21±3.36) days. All patients underwent best corrected visual acuity (BCVA) and optical coherence tomography (OCT) examination. BCVA examination was performed using the international standard visual acuity chart, which was converted to the logarithm of the minimum angle of resolution (logMAR) visual acuity during statistics. The central macular thickness (CMT) was measured by spectral domain-OCT. The average size of SMH was (6.82±1.53) DD. The logMAR BCVA 1.73±0.44; CMT was (727.96±236.40) μm. All patients were treated with 23G pars plana vitrectomy combined with subretinal injection of tPA and intravitreal injection of Conbercept. At 1, 3, 6 and 12 months after treatment, the same equipment and methods were used for relevant examinations before treatment. The changes of BCVA and CMT, the clearance rate of macular hemorrhage, and the complications during and after surgery were observed. BCVA and CMT before and after treatment were compared by repeated measures analysis of variance.Results:Compared with before treatment, BCVA gradually increased at 1, 3, 6 and 12 months after treatment, and the differences were statistically significant ( F=77.402, P<0.001). There was no significant difference in BCVA between any two groups at different time points after treatment ( P>0.05). Correlation analysis showed that BCVA at 12 months after treatment was negatively correlated with the course of disease ( r=-0.053, P=0.774). One week after treatment, macular hemorrhage was completely cleared in 30 eyes (93.75%, 30/32). The CMT was (458.56±246.21), (356.18±261.46), (345.82±212.38) and (334.64±165.54) μm at 1, 3, 6 and 12 months after treatment, respectively. Compared with before treatment, CMT decreased gradually after treatment, and the difference was statistically significant ( F=112.480, P<0.001). There were statistically significant differences in different follow-up time before and after treatment ( P<0.001). The number of treatments combined with Conbercept during and after surgery was (4.2±1.8) times. At the last follow-up, there was no recurrence of SMH, retinal interlamellar effusion and other complications. Conclusion:Subretinal injection of tPA combined with intravitreal injection of Conbercept is safe and effective in the treatment of large SMH secondary to PCV, and it can significantly improve the visual acuity of patients.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the changing distribution and antibiotic resistance profiles of clinical isolates of Staphylococcus in hospitals across China from 2015 to 2021.Methods Antimicrobial susceptibility testing was conducted for the clinical isolates of Staphylococcus according to the unified protocol of CHINET(China Antimicrobial Surveillance Network)using disk diffusion method and commercial automated systems.The CHINET antimicrobial resistance surveillance data from 2015 to 2021 were interpreted according to the 2021 CLSI breakpoints and analyzed using WHONET 5.6.Results During the period from 2015 to 2021,a total of 204,771 nonduplicate strains of Staphylococcus were isolated,including 136,731(66.8％)strains of Staphylococcus aureus and 68,040(33.2％)strains of coagulase-negative Staphylococcus(CNS).The proportions of S.aureus isolates and CNS isolates did not show significant change.S.aureus strains were mainly isolated from respiratory specimens(38.9±5.1)％,wound,pus and secretions(33.6±4.2)％,and blood(11.9±1.5)％.The CNS strains were predominantly isolated from blood(73.6±4.2)％,cerebrospinal fluid(12.1±2.5)％,and pleural effusion and ascites(8.4±2.1)％.S.aureus strains were mainly isolated from the patients in ICU(17.0±7.3)％,outpatient and emergency(11.6±1.7)％,and department of surgery(11.2±0.9)％,whereas CNS strains were primarily isolated from the patients in ICU(32.2±9.7)％,outpatient and emergency(12.8±4.7)％,and department of internal medicine(11.2±1.9)％.The prevalence of methicillin-resistant strains was 32.9％in S.aureus(MRSA)and 74.1％in CNS(MRCNS).Over the 7-year period,the prevalence of MRSA decreased from 42.1％to 29.2％,and the prevalence of MRCNS decreased from 82.1％to 68.2％.MRSA showed higher resistance rates to all the antimicrobial agents tested except trimethoprim-sulfamethoxazole than methicillin-susceptible S.aureus(MSSA).Over the 7-year period,MRSA strains showed decreasing resistance rates to gentamicin,rifampicin,and levofloxacin,MRCNS showed decreasing resistance rates to gentamicin,erythromycin,rifampicin,and trimethoprim-sulfamethoxazole,but increasing resistance rate to levofloxacin.No vancomycin-resistant strains were detected.The prevalence of linezolid-resistant MRCNS increased from 0.2％to 2.3％over the 7-year period.Conclusions Staphylococcus remains the major pathogen among gram-positive bacteria.MRSA and MRCNS were still the principal antibiotic-resistant gram-positive bacteria.No S.aureus isolates were found resistant to vancomycin or linezolid,but linezolid-resistant strains have been detected in MRCNS isolates,which is an issue of concern.

Objective:To explore the clinical characteristics and distribution of Tranditional Chinese Medicine (TCM) syndrome types of refractory tic disorders in children based on clustering analysis.Methods:A cross-sectional study. 183 children aged 3-18 years with refractory tic disorders from pediatric encephalopathy outpatient department of the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine who met the inclusion criteria from October 2015 to January 2022 were recruited. Frequency descriptive analysis, systematic clustering analysis and principal component analysis were conducted by Microsoft Office Excel 2016 and IBM SPSS Statistics 26.0 to explore the clinical characteristics and syndrome distribution of the disease.Results:The TCM symptoms of 183 children with refractory tic disorders were clustered into 6 categories, and finally 5 types of syndrome were obtained, among which the syndrome of spleen deficiency and liver hyperactivity mixed with dampness accounted for the largest proportion (27.32%), followed by the syndrome of phlegm-fire disturbing spirit (21.31%), the syndrome of wind-heat invading lung (18.03%), the syndrome of phlegm-qi stagnation (17.49%), and the syndrome of dampness and yin deficiency (15.85%).Conclusion:Through the mining and analysis of the outpatient information of pediatric encephalopathy in our hospital, the common syndrome differentiation types of refractory tic disorder are obtained, which can provide a reference for the TCM syndrome differentiation types of refractory tic disorder in children.

Chorea is a rare adverse effect of phenytoin and is common in children, with widely variable clinical presentations. This article reported a case of an elderly woman presented chorea without nystagmus, ataxia, dysarthria and other typical vestibular-cerebellar symptoms, who took compound theophylline and ephedrine contained phenytoin to treat asthma for 1 year. The serum phenytoin concentrations were at toxic levels and chorea disappeared within 3 days after discontinuation of the drug. The clinical features of previously reported cases of phenytoin-induced chorea were also summarized.

The epitranscriptomic mark N⁶-methyladenosine (m⁶A), which is the predominant internal modification in RNA, is important for plant responses to diverse stresses. Multiple environmental stresses caused by the tea-withering process can greatly influence the accumulation of specialized metabolites and the formation of tea flavor. However, the effects of the m⁶A-mediated regulatory mechanism on flavor-related metabolic pathways in tea leaves remain relatively uncharacterized. We performed an integrated RNA methylome and transcriptome analysis to explore the m⁶A-mediated regulatory mechanism and its effects on flavonoid and terpenoid metabolism in tea (Camellia sinensis) leaves under solar-withering conditions. Dynamic changes in global m⁶A level in tea leaves were mainly controlled by two m⁶A erasers (CsALKBH4A and CsALKBH4B) during solar-withering treatments. Differentially methylated peak-associated genes following solar-withering treatments with different shading rates were assigned to terpenoid biosynthesis and spliceosome pathways. Further analyses indicated that CsALKBH4-driven RNA demethylation can directly affect the accumulation of volatile terpenoids by mediating the stability and abundance of terpenoid biosynthesis-related transcripts and also indirectly influence the flavonoid, catechin, and theaflavin contents by triggering alternative splicing-mediated regulation. Our findings revealed a novel layer of epitranscriptomic gene regulation in tea flavor-related metabolic pathways and established a link between the m⁶A-mediated regulatory mechanism and the formation of tea flavor under solar-withering conditions.
