OBJECTIVE To establish population pharmacokinetic model of levetiracetam （Lev） for Chinese patients with post- stroke epilepsy （PSE）， and provide reference for formulating individualized dosing regimens for Lev therapy in this specific population. METHODS Blood concentration data and clinical diagnosis and treatment information of PSE patients meeting the inclusion criteria were retrospectively collected and divided into model group and validation group at an 8∶2 ratio using a random number method. Based on the model group data， a population pharmacokinetic model was developed using nonlinear mixed-effects modeling. Internal evaluation was performed through goodness-of-fit tests and bootstrap analysis， while external validation was conducted using the validation group data. RESULTS A total of 75 blood concentration measurements from 70 PSE patients were collected， with 60 measurements from 55 patients used for model development and 15 measurements from 15 patients reserved for external validation. The final model estimated a population typical value of clearance at 2.98 L/h. Estimated glomerular filtration rate， daily dose， and homocysteine level significantly influenced clearance of Lev （P＜0.01）. The model demonstrated satisfactory predictive performance， as evidenced by goodness-of-fit tests， bootstrap analysis， and external validation results. CONCLUSIONS Daily dose， estimated glomerular filtration rate， and homocysteine level are identified as significant covariates influencing Lev clearance in Chinese PSE patients. When making clinical decisions， comprehensive consideration should be given to the patient’s treatment response， physiological and pathological conditions， and the occurrence of adverse reactions， etc. The dosage of Lev should be adjusted based on the results of population pharmacokinetic model.

Objective: To investigate the self-monitoring blood pressure behavior and its influencing factors among residents in Jiangsu Province, so as to provide the basis for strengthening proactive blood pressure monitoring among residents. Methods: Permanent residents aged 35-75 years in six counties (cities, districts), Jiangsu Province, were selected using the stratified cluster sampling method in 2023. Data on basic information, disease history, and self-monitoring blood pressure behavior were collected, height and weight were measured to calculate the body mass index (BMI); and blood glucose and lipid levels were measured. Self-monitoring blood pressure behavior was defined as having measured blood pressure at least once in the past three months. Factors affecting self-monitoring blood pressure behavior were identified using a multivariable logistic regression model. Results: A total of 12 475 residents were surveyed, including 5 748 males and 6 727 females, with a male-to-female ratio of 1∶1.17. There were 3 855 residents aged 45-<55 years (30.90%) and 5 511 residents who had self-monitoring blood pressure behaviors (44.18%). Multivariable logistic regression analysis showed that the residents who were males (OR=1.167, 95%CI: 1.081-1.261), lived in rural areas (OR=1.430, 95%CI: 1.321-1.547), aged 45-75 years (45-<55 years, OR=1.384, 95%CI: 1.241-1.543; 55-<65 years, OR=1.397, 95%CI: 1.243-1.570; 65-75 years, OR=1.196, 95%CI: 1.049-1.363), had an annual household income ≥30 000 yuan (30 000-<60 000 yuan, OR=1.190, 95%CI: 1.072-1.321; 60 000-<110 000 yuan, OR=1.330, 95%CI: 1.191-1.485; ≥110 000 yuan, OR=1.746, 95%CI: 1.536-1.984), were overweight (OR=1.170, 95%CI: 1.070-1.280) or obese (OR=1.248, 95%CI: 1.120-1.391), were unaware (OR=1.221, 95%CI: 1.103-1.353) or aware (OR=3.937, 95%CI: 3.575-4.335) of having hypertension, were aware of having diabetes (OR=1.538, 95%CI: 1.354-1.749), and aware of having dyslipidemia (OR=1.265, 95%CI: 1.106-1.447) were more likely to have self-monitoring blood pressure behaviors. Conclusions Among the residents aged 35-75 years in Jiangsu Province, 44.18% had self-monitoring blood pressure behavior. Gender, place of residence, age, annual household income, BMI, hypertension, diabetes, and dyslipidemia were identified as influencing factors for self-monitoring blood pressure behavior.

Objective:To summarize the clinical phenotype and genetic characteristics of children with neurodegeneration caused by UBTF gene mutations in childhood. Methods:The clinical and genetic data of 3 children with neurodegeneration in childhood diagnosed in the Department of Neurology, Children′s Hospital Affiliated to Zhengzhou University from February 2020 to January 2023 were retrospectively analyzed. All the 3 probands were found having UBTF gene mutations through the whole exome gene sequencing, and the first generation Sanger sequencing method was used to verify the UBTF gene in their family members. The variation characteristics of the UBTF gene were analyzed, and the treatment and follow-up results of the 3 children were summarized. Results:Among the 3 children with childhood onset neurodegeneration, 2 were male and 1 female, aged 9 months, 4 years and 6 months after birth, respectively. The clinical phenotypes mainly included motor retardation, speech and mental retardation, and dystonia. Among them, case 1 and case 2 had seizures, case 1 had dysphagia, feeding problems, no weight gain and ataxia. Brain MRI plain scan showed that case 1 and case 2 had different degrees of cerebral atrophy, case 1 had hypoplasia of corpus callosum, ventricle expansion and softening focus, and case 3 showed non-specific widening of the subarachnoid space. There were no abnormalities in the chromosome copy number variation and mitochondrial ring gene testing in the 3 children; the whole exon gene testing suggested the de novo missense variant in the UBTF gene [NM_014233.4: c.1414(exon14) G>A (p.Gly472Ser), c.1392(exon14)G>T(p.Lys464Asn)] and the maternal nonsense variant [NM_014233.4:c.520C>T(p.Arg174 *)], which were unreported site variants. In terms of treatment, the 3 children received comprehensive rehabilitation function training, and achieved a certain degree of language and intelligence improvement. Seizure control was effectively managed in case 1 with a single antiepileptic drug. Epileptic seizures were effectively treated and controlled in case 2 using more than 4 types of antiepileptic drugs. Conclusions:Neurodegenerative changes caused by UBTF gene mutations in childhood are relatively rare, and some cases may be accompanied with brain atrophy. De novo missense variation and maternal nonsense variation of the UBTF gene are the genetic etiology of the 3 probands.

BACKGROUND:The repair process of skin trauma is complex and susceptible to infection,easy to lead to poor healing,is the current difficulty and hot spot in wound repair research,and has received extensive attention in the fields of traditional Chinese medicine and tissue engineering. OBJECTIVE:To investigate the effect of moxibustion and reduced graphene oxide/cerium oxide nanocomposite on promoting the healing of infectious wounds. METHODS:(1)Reduced graphene oxide/cerium dioxide nanocomposites with mass ratios of 2:1,1:1 and 1:2 were synthesized by hydrothermal method.The resulting composites were recorded as G2C1,G1C1 and G1C2,respectively.The photothermal properties,cytotoxicity and antibacterial properties of the three kinds of materials were tested.After taking moxa sticks,three kinds of moxibustion distances were set(3.0-3.5 cm,recorded as moxibustion 1;2.5-3.0 cm,recorded as moxibustion 2;2.0-2.5 cm,recorded as moxibustion 3).Moxibustion was applied to the surface of human skin for 10 minutes to detect the photothermal properties.The antibacterial properties of moxibustion were tested at three different distance intervals.Simultaneously,the back body surface infrared imaging of rats with different mass concentrations of G1C1 material,moxibustion(three kinds of moxibustion distances)and moxibustion 2+G1C1 material was detected.(2)Sixty male Sprague-Dawley rats were selected to model the wound of Staphylococcus aureus infection.48 hours later,they were randomly divided into 10 groups with 6 rats in each group:control group(did not receive any treatment),mupirocin group,moxibustion 2+G1C1 group,moxibustion 1 group,moxibustion 2 group,moxibustion 3 group and 60,80,100,and 120 μg/mL G1C1 groups(The G1C1 group was given 808 nm near-infrared laser irradiation for 10 min/time,and the G1C1 suspension was loaded on the wound surface before each treatment.Each group of moxibustion underwent in-situ suspension moxibustion,and the intervention time was 10 min/time.Moxibustion 2+G1C1 group was loaded with G1C1 suspension on the wound surface before each treatment,and moxibustion was suspended in situ with moxa strips,and the intervention time was 10 min/time).The frequency of treatment was 2 days once.Wound healing,wound colony count and repair were detected after 7 days of intervention. RESULTS AND CONCLUSION:(1)The three kinds of reduced graphene oxide/cerium dioxide nanocomposites had good photothermal properties,and the higher the mass concentration of the composites,the better the photothermal properties.The temperature of the moxibustion 2 group reached 47.6 ℃for 10 minutes without causing thermal damage,which was more suitable for animal experiments.The results of co-culture with NIH-3T3 cells exhibited that 60,80,and 100 μg/mL G1C1 had good biocompatibility.The results of a co-culture experiment with Staphylococcus aureus suspension displayed that G2C1,G1C1 and G1C2 had good antibacterial activity,among which G1C1 group demonstrated excellent antibacterial performance,and the antibacterial rate reached 100％when its mass concentration was 80 μg/mL.60-120 μg/mL G1C1 could effectively remove Staphylococcus aureus biofilm,and the higher the material mass concentration,the better the removal effect.Moxibustion could also effectively remove Staphylococcus aureus biofilm,and the closer the moxibustion was,the better the removal effect.(2)Compared with the control group,the wound area of the mupirocin group,moxibustion 2 group,moxibustion 2+G1C1 group and 80,100 μg/mL G1C1 groups was significantly reduced on day 7 of treatment,and the quality of wound repair was better.Mupirocin,G1C1,moxibustion and moxibustion 2+G1C1 could effectively remove the residual bacteria on the wound surface,and the higher the mass concentration of G1C1,the lower the residual bacteria.Among them,the wound repair efficiency and bacterial residue of 80 μg/mL G1C1 group and moxibustion 2 group were very similar,and the wound repair efficiency of both was better than that of mupirocin group.In addition,it was also observed that the combination of materials and moxibustion had a better ability to clear wound bacteria than that used alone.(3)The results confirm that moxibustion,reduced graphene oxide/cerium dioxide nanocomposites and their combination have good anti-infection and wound healing effects.

Objective To explore the potential categories and influencing factors of the fear of progression in patients with inflammatory bowel diseases(IBD).Methods IBD patients who received inpatient treatment in a tertiary hospital in Nanjing from July 2022 to July 2023 were selected as the study subjects by convenience sampling method.The General Demographic Information Questionnaire,the Chinese version of the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),the Chinese version of Inflammatory Bowel Disease Self-efficacy Scale(IBD-SES),and Social Support Rating Scale(SSRS)were administered to the participants.We applied one-way ANOVA and Logistic regression analysis to identify the factors associated with the potential categories of the fear of progression.Results A total of 303 retumed questionnaires(out of the 310)were valid,resulting an effective response rate of 97.74％.According to the results of latent profile analysis,we classified the respondents into 3 categories by the fear of progression,namely"low risk fear of disease adaptation group"(n=127,41.91％),"medium risk fear of illness distress group"(n=139,45.88％),"high risk fear of dysfunction group"(n=37,12.21％).3 groups showed statistically significant differences in permanent address,self-rated financial pressure,current disease status and self-efficacy(P＜0.05).Conclusion Patients with IBD had obvious differences in characteristics on the fear of progression.Nursing personnel should formulate personalized intervention strategies based on the classification characteristics of the fear of progression of IBD patients.Moreover,nurses should focus on improving patients'self-efficacy and promoting patients to treat medical care,stress and emotion management correctly.

This paper summarized the experience of Professor FANG Dingya in staged treatment of Sjögren's syndrome from the perspective of dryness toxin. It is believed that the cause of Sjögren's syndrome is externally-contracted dryness， consumption of essence and fluid， congenital and acquired essence deficiency， depleted essence and insufficient blood， and the core mechanism is internal accumulation of dryness toxin. The treatment can be divided into three stages， that is dryness toxin transforming into fire-heat， damp-heat and phlegm-stasis， from the perspective of dryness metal qi transformation. It is emphasized to dispel pathogen mainly， to clear and moisten with yin-nourishing medicinals in supplementation， and to treat by stages based on syndrome differentiation. For dryness toxin with fire-heat， it is suggested to moisten dryness， resolve toxins and subdue fire， with self-made Runzao Jiedu Decoction （润燥解毒汤） in modification. For dryness toxin with damp-heat， the method of nourishing yin， clearing heat and draining dampness should be used， and Chunze Decoction （春泽汤） in modification is suggested. For dryness toxin with phlegm-stasis， it is recommended to unblock collaterals， disperse phlegm and dissipate stasis， with self-made Sanyu Xiaotan Decoction （散瘀消痰汤） in modification.

Objective To investigate the construction and value of radiation pneumonitis(RP)predic-tive model based on machine learning algorithm.Methods A retrospective analysis was conducted on the clin-ical data in 77 patients with breast cancer receiving radiotherapy and regular follow-up in this hospital from August 2019 to September 2022.The affected side lung was delineated on the localization CT as the area of in-terest and the radiomics features were extracted,meanwhile the affected side lung dosimetric parameters were extracted.After feature screening,the patients were divided into the training set and testing set by a 7∶3 rati-o.The features of positioning CT radiomics were extracted and combined with the dosimetry parameters of the affected side lung,and the model was established by using stochastic gradient descent(SGD)algorithm.The performance of the model was validated by using the area under the receiver operating characteristic(ROC)curve(AUC)and decision curve analysis(DCA).Results Among 77 patients,24 cases developed RP after ra-diotherapy end with an incidence rate of 31.17％.Compared with the patients without RP occurrence,V5,V10,V15,V20,V25,V30 and mean lung dose(MLD)in the patients with RP occurrence were higher,and the differ-ence was statistically significant(P＜0.05).In the training set,36 cases did not develop RP.17 cases devel-oped RP,in the testing set,17 cases did not develop RP and 7 cases developed RP.The affected side lung dosi-metric parameters had no statistical difference between the training set and testing set with and without RP occurrence(P＞0.05).After characteristics screening,the 8 optimal characteristics combinations were finally obtained.The average AUC of SGD model in 50％off cross-validation of the training set was 0.900 and AUC in the test set was 0.882.Conclusion The positioning CT radiomics features combined with dosimetry param-eters of the affected side lung has the good predictive value for RP after breast cancer radiotherapy.
