Objective:To analyze the medication law of TCM oral prescriptions in the treatment of postherpetic neuralgia (PHN).Methods:The effective cases and clinical studies about TCM oral prescriptions in the treatment of PHN were retrieved from CNKI, Wanfang Data, VIP, and CBM from January 1, 2002 to December 31, 2021. The medication frequency and drug properties were counted through the Ancient and Modern Medical Record Cloud Platform, and correlation analysis, cluster analysis and complex network analysis were performed.Results:A total of 233 articles were included, involving 243 prescriptions and 191 kinds of Chinese materia medica. There were 20 kinds of Chinese materia medica with frequency >40, most of which have the efficacy of promoting blood circulation to remove blood stasis. The Chinese materia with heat-clearing and detoxifying efficacy were also often used. The properties were mainly warm, mild, slight cold, and cold, tastes were mainly bitter, pungent and sweet, and meridians were mainly liver, spleen and heart meridians. The association rule analysis was used to obtain 15 commonly used TCM groups. The commonly used Chinese materia medica could be clustered into 4 categories. The core prescription obtained by complex network analysis was Angelicae Sinensis Radix, Glycyrrhizae Radix et Rhizoma, Corydalis Rhizoma, Bupleuri Radix, Carthami Flos, Paeoniae Radix Alba, Persicae Semen, Chuanxiong Rhizoma, and Rehmanniae Radix.Conclusion:TCM oral prescriptions for the treatment of PHN put promoting blood circulation to remove blood stasis and activating meridians to stop pain in priority, taking into account the clearing heat, regulating qi and blood.

Objective:To summarize the clinical and genetic characteristics of children with epilepsy associated with SCN2A gene variations. Methods:A retrospective study was performed. Eleven children with epilepsy admitted to Department of Pediatric Neurology, Linyi People's Hospital from January 2017 to December 2022 were included; all of them had pathogenic SCN2A gene mutation. Genetic results and clinical data as epileptic seizure type/frequency, intelligence and motor development of these 11 children were collected. Epilepsy-related variations and pathogenesis of SCN2A gene were analyzed, and their correlations with clinical phenotypes in these children were analyzed. Results:Among the 11 patients, 6 had self-limited epilepsy (4 with variation in the intracellular domain and 2 in the transmembrane domain), 1 had febrile convulsion accompanied by childhood absent epilepsy (with variation in the intracellular domain), and 4 had developmental epileptic encephalopathy (2 with variation in the extracellular domain and 2 with variation in the transmembrane domain). SCN2A gene was missense mutation in these 11 children, and the mutation site in 6 children was not reported before. Various forms of video EEG discharge were noted, and 1 child with self-limited epilepsy showed transient multifocal epileptic discharge during frequent seizures. Oxcarbazepine and topiramate were effective for self-limiting epilepsy, and lamotrigine was effective in 1 child with late-onset epileptic encephalopathy. Eleven patients were followed up for (66±32) months; the age ranged from 8 months to 11 years and 6 months at the last follow-up; 10 patients had seizure remission and 1 had uncontrolled seizure. Conclusions:Besides self-limited epilepsy and developmental epileptic encephalopathy, SCN2A gene mutations are also associated with febrile convulsion and childhood absent epilepsy. Phenotypic differences are highly correlated with mutation locations; developmental epileptic encephalopathy associated variants are mostly located in extracellular domains, while self-limited epileptic variants are mostly located in intracellular domains.

Objective:By exploring the source of children's total fluoride intake and the relationship between children's total fluoride intake and dental fluorosis prevalence, to calculate the benchmark dose (BMD) of children's total fluoride intake and its 95% confidence lower limit (BMDL), and to provide the basis for revision of "Total Fluoride Intake for Inhabitants" (WS/T 87-2016).Methods:The villages that had water improvement for 5 years and more in 6 provinces of Jiangsu, Shandong, Hebei, Anhui, Henan and Shaanxi were selected as survey sites in April 2014. The water fluoride content of these villages was 0.3 - 3.0 mg/L, tap water samples from the centralized water supply were collected, and fluoride content was detected by ion selective electrode method. Children aged 8 to 12 years were selected, children's dental fluorosis was checked by Dean's method. Children's dietary and drinking water volume were surveyed by duplicate portion study (measurement for 3 d), and dietary fluoride content was detected according to the "Method for Determination of Fluorine in Foods". The mean and standard deviation of drinking water fluoride intake, dietary fluoride intake, and total fluoride intake were measured. According to the dose-response relationship between children's total fluoride intake and the detection rate of dental fluorosis, BMD and BMDL were calculated, and the reference dose (RfD) was calculated based on BMDL.Results:The mean of water fluoride of all 29 villages was 1.26 mg/L (from 0.41 to 2.85 mg/L). Totally 3 043 children aged 8 to 12 years were checked, and the detection rate of dental fluorosis was 30.2% (919/3 034). The lowest detection rate of dental fluorosis was 2.0% (2/100) and the highest was 71.4% (30/42) in the 29 villages. The children's dietary and drinking water volume of 769 person-time aged 8 to 12 years were surveyed, the children's daily drinking water fluoride intake, dietary fluoride intake, and total fluoride intake were (0.83 ± 0.66), (1.13 ± 0.61) and (1.96 ± 0.89) mg/d, respectively. The BMD of children's daily total fluoride intake was 2.43 mg, the BMDL was 2.21 mg, and the RfD was 2.21 mg.Conclusion:The BMD of 8 to 12 years old children's daily total fluoride intake is the same as the allowable limit (2.4 mg) of the national standard "Total Fluoride Intake for Inhabitants" (WS/T 87-2016).
