Objective This study aims to assess the current status of pharmaceutical management in county medical communities in Hubei province,and provide recommendations for the homogenization,standardization,and regulation of pharmaceutical management in these communities.It also intends to offer decision-making support for health administrative departments,and provide reference experiences for management in other regions.Methods The current status of pharmaceutical management in county medical communities in Hubei province was conducted through a questionnaire survey and field research.Existing problems were analyzed,key management areas were identified,and reasonable recommendations were proposed.Results Pharmaceutical management in county medical communities has significant shortcomings in organizational structure,system construction,personnel allocation,key link control,and the leading unit's outreach capabilities.These deficiencies are not aligned with the high-quality development of pharmacy in the new era.Conclusions It is recommended that county medical communities should establish a comprehensive pharmaceutical management quality control system.This can be achieved by improving organizational management,strengthening talent development,enhancing core systems,setting monitoring indicators,and increasing outreach capabilities.Additionally,evaluation standards for the quality control system of pharmaceutical management should be established to enhance management capabilities through scientific assessment and positive feedback.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

AIM: To explore the characteristics of astigmatism in preschool children before, during and after the COVID-19 epidemic, so as to provide a reference for further prevention and control of children's vision.METHODS: In the consecutive four years from January 2018 to December 2021, a retrospective analysis of vision data was conducted on 2 273 preschool children(4 546 eyes)younger than 4 years old who participated in children's vision screening test in Baiyun district, Guangzhou. They were divided into 1-year old group(ages<1-year old, 420 cases), 2-year old group(1-year ≤ ages <2-year, 543 cases), 3-year old group(2-year ≤ages <3-year, 614 cases), and 4-year old group(3-year ≤ ages<4-year, 696 cases)according to ages. The analysis included astigmatic degrees of children's eyes as well as their conditions of astigmatism.RESULTS: In 2018, the astigmatic degrees of the both eyes of 1-year-old group were higher than those of other groups(P<0.05). The binocular astigmatic degrees of the preschool children in four groups were obviously higher in 2020 than 2019(P<0.05), while they were significantly decreased in 2021 when compared with 2020(P<0.05). From 2019 to 2020, the increase of astigmatic degrees of the right eye is more considerable than the left eye of preschool children in those four groups(P<0.001). Furthermore, the morbidity of astigmatism basically echoes with the changing tendency of astigmatic degrees from 2018 to 2021.CONCLUSIONS: Preschool children in Baiyun district, Guangzhou, have the highest degree of astigmatism and the fastest progression rate within 1 year old. Before COVID-19 epidemic, the changes in astigmatism and prevalence were relatively stable; during COVID-19 epidemic, the astigmatism and prevalence increased significantly and the astigmatic degrees of right eye increased more than that of the left eye; after the normalization of epidemic prevention and control, the astigmatism and prevalence decreased significantly.

The many-banded krait, Bungarus multicinctus, has been recorded as the animal resource of JinQianBaiHuaShe in the Chinese Pharmacopoeia. Characterization of its venoms classified chief phyla of modern animal neurotoxins. However, the evolutionary origin and diversification of its neurotoxins as well as biosynthesis of its active compounds remain largely unknown due to the lack of its high-quality genome. Here, we present the 1.58 Gbp genome of B. multicinctus assembled into 18 chromosomes with contig/scaffold N50 of 7.53 Mbp/149.8 Mbp. Major bungarotoxin-coding genes were clustered within genome by family and found to be associated with ancient local duplications. The truncation of glycosylphosphatidylinositol anchor in the 3'-terminal of a LY6E paralog released modern three-finger toxins (3FTxs) from membrane tethering before the Colubroidea divergence. Subsequent expansion and mutations diversified and recruited these 3FTxs. After the cobra/krait divergence, the modern unit-B of β-bungarotoxin emerged with an extra cysteine residue. A subsequent point substitution in unit-A enabled the β-bungarotoxin covalent linkage. The B. multicinctus gene expression, chromatin topological organization, and histone modification characteristics were featured by transcriptome, proteome, chromatin conformation capture sequencing, and ChIP-seq. The results highlighted that venom production was under a sophisticated regulation. Our findings provide new insights into snake neurotoxin research, meanwhile will facilitate antivenom development, toxin-driven drug discovery and the quality control of JinQianBaiHuaShe.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

OBJECTIVE: To establish the droplet digital PCR (ddPCR) assay for the detection of NPM1 type A mutation in patients with acute myeloid leukemia (AML), and to evaluate its specificity, sensitivity and its value in clinical application. METHODS: NPM1 mutant and wildtype plasmids were used to verify the performance of ddPCR. Both ddPCR and Sanger sequencing were used to detect the bone marrow samples of 87 AML patients, which were confirmed by next generation sequencing (NGS). Moreover, NPM1 mutation burden was dynamically monitored in five patients by ddPCR. RESULTS: The limit of blank (LOB) of ddPCR established for NPM1 mutation detection was 1.1 copies/μl, and the limit of detection (LOD) was 2.43 copies/μl, which had good linearity. Among the 87 newly diagnosed AML patients, ddPCR identified seventeen cases positive for NPM1 mutation (19.5%)， which was consistent with Sanger sequencing. NGS confirmed 12 positive cases, including 8 of type A mutations, 2 of type D mutations, and 2 of rare type mutations. The results of dynamic monitoring of NPM1 mutation burden in 5 patients showed that the NPM1 mutation burden decreased obviously even close to 0, when patients achieve complete remission after chemotherapy. However, the mutation burden was increased again at the time of relapse. CONCLUSION In this study, we established a ddPCR method for detection of NPM1 mutation with good sensitivity and repeatability, which can be used for screening NPM1 mutation in newly diagnosed AML patients and for minimal residual disease monitoring after remission in positive AML patients to guide treatment.

ObjectiveTo explore the therapeutic effect and possible mechanism of Banxia Xiexintang and its disassembled prescriptions in regulating the flora disorder induced by mixed antibiotics in young rats. MethodSeventy male BALB/C young rats were randomly assigned into 7 groups： blank group， model group， Bifidobacterium tetralogy viable tablets （0.68 g·kg^-1） group， Banxia Xiexintang （9.1 g·kg^-1） group， Xinkai （3.19 g·kg^-1） group， Kujiang （1.82 g·kg^-1） group， and Ganbu （4.1 g·kg^-1） group， with 10 rats in each group. Except the blank group， the other groups were given mixed antibiotics by gavage to induce intestinal flora disorder. After 14 days， the rats in different drug groups were administrated with corresponding drugs by gavage， and those in the blank group and model group with the same amount of normal saline once a day for 14 days. After that， fecal samples were collected aseptically for 16S rDNA sequencing of intestinal flora， and lipopolysaccharide （LPS， 10 mg·kg^-1） was injected intraperitoneally to induce inflammatory reaction. The tissue morphology of colonic mucosa was observed via hematoxylin-eosin （HE） staining， and the macrophage infiltration of colonic mucosa was observed via toluidine blue staining and immunohistochemistry. The expression of interleukin-1β （IL-1β）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， tumor necrosis factor-α （TNF-α）， and interleukin-10 （IL-10） mRNA were determined by real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the blank group， the modeling changed the intestinal flora structure of the young rats （P<0.01）， damaged the colonic mucosa， reduced the macrophage infiltration， and down-regulated the mRNA levels of IL-1β， IL-6， IL-8， TNF-α， and IL-10 （P<0.01）. Compared with the model group， bifidobacterium quadruple viable tablets， Banxia Xiexintang and its disassembled prescriptions increased the diversity of intestinal flora and the relative abundance of beneficial bacteria such as Bacteroidetes and Firmicutes （P<0.01）. At the same time， they ameliorated colonic mucosal injury （P<0.05， P<0.01）， increased macrophage infiltration （P<0.05， P<0.01）， and up-regulated the mRNA levels of IL-6， IL-8， and TNF-α （P<0.01）. The mRNA level of IL-1β was up-regulated in Bifidobacterium tetralogy viable tablets， Banxia Xiexintang， Kujiang， and Ganbu groups （P<0.01）， and that of IL-10 was up-regulated in Bifidobacterium tetralogy viable tablets， Banxia Xiexintang， Xinkai， and Ganbu groups （P<0.01）. ConclusionBanxia Xiexintang and the disassembled prescriptions can adjust the intestinal flora of young rats exposed to antibiotics and protect the immune barrier of colonic mucosa after intestinal flora disorder. In particularly， the whole prescription of Banxia Xiexintang demonstrates the best performance.
