OBJECTIVE To address the management challenges encountered by inpatient pharmacy of our hospital in undertaking “internet-based medicine delivery” （IMD） services， and to improve service efficiency and medication safety. METHODS SWOT analysis method was applied to systematically examine both internal and external factors， formulate comprehensive management strategies， and restructure the service processes. Process optimization included： establishing a closed-loop process for dispensing and returning drugs based on the drug traceability codes； unifying the drug inventory of the inpatient pharmacy with that of IMD， optimizing the management of storage locations； improving the inventory management function of the hospital information system， and adjusting the inventory counting plan and shift scheduling rules. The indicators of the inpatient pharmacy， including inventory structure， dispensing efficiency， inventory checks accuracy rate， the rationality rate of prescription， and consistency rate of human-machine review， were compared before and after the implementation of the strategies to evaluate the implementation effects. RESULTS After implementation， the structure of the drug inventory was significantly optimized. The proportion of drugs approaching their expiration dates decreased by 35.55%， the proportion of unsold drugs decreased by 64.52%， and the proportion of drugs that had been accumulated for more than 4 weeks decreased by 33.26%. The speed of prescription dispensing increased by 34.92%， and the daily drug requisition time was shortened by 62.03%. The accuracy rate of inventory checks rose from 86.33% to 90.33%， while the rationality rate of prescriptions and the consistency rate of human-machine review rose from 86.00% and 89.33% to 95.00% and 97.00% respectively. Furthermore， the launch of the drug traceability system reduced external dispensing errors from 4 to 1. CONCLUSIONS The comprehensive management strategy based on SWOT analysis can effectively improve the quality of drug management in the inpatient pharmacy and the operational efficiency of IMD， ensuring timely and safe medication for patients.

ObjectiveTo construct and validate a clinical prediction model for Qi deficiency and blood stasis syndrome in chronic heart failure （CHF），aiming to assist clinical diagnosis and provide tools and methods for individualized treatment of CHF. MethodsThe clinical data of patients with chronic heart failure treated at Dongzhimen Hospital of Beijing University of Chinese Medicine from January 2022 to January 2024 were retrospectively collected. The patients were randomly divided into a training group and a validation group with a ratio of 7∶3. First， the least absolute shrinkage and selection operator （LASSO） regression analysis was used to preliminarily screen the predictive factors affecting the diagnosis of Qi deficiency and blood stasis syndrome in CHF. Subsequently， the Logistic regression method was applied to conduct a more in-depth and detailed analysis of these factors. Variables with P<0.05 in the results of the multi-factor Logistic regression were carefully selected and included. Based on the regression coefficients obtained from this analysis， a model was constructed， and a nomogram was accurately drawn. Using R software，the receiver operating characteristic （ROC） curve，calibration curve，and decision curve analysis （DCA） were precisely drawn. These analyses were used to comprehensively evaluate the model from three crucial aspects： discrimination，calibration，and clinical applicability. Additionally， the accuracy，specificity，sensitivity，positive predictive value，and negative predictive value of the model were meticulously calculated to conduct a more all-round and comprehensive assessment. ResultsIn total， 168 cases were successfully obtained in the training group， and 71 cases were included in the validation group. After a thorough comparison， it was found that there were no statistically significant differences in the baseline data between the two groups. After being rigorously screened by the LASSO-multivariate logistic regression method， dark red tongue，smoking history，cardiac troponin I，and N-terminal pro-B-type natriuretic peptide （NT-ProBNP） were identified as the influencing factors for diagnosing patients with the Qi deficiency and blood stasis syndrome in CHF. The constructed model demonstrated an area under the curve （AUC） of 0.812 in the training group and 0.719 in the validation group. The calibration curve showed that the predicted curve of the model was close to the actual observed curve. DCA indicated that the model could provide substantial clinical benefits for patients at the decision thresholds ranging from 0.2 to 0.9. ConclusionThe clinical prediction model for Qi deficiency and blood stasis syndrome in chronic heart failure constructed in this study shows good performance. It has certain application value in clinical practice， which may contribute to the improvement of the diagnosis and treatment of CHF patients with this syndrome.

ObjectiveTo observe the effectiveness and safety of Jiuzihuichun decoction combined with spleen- strengthening moxibustion in patients with asthenospermia infertility with spleen-kidney deficiency pattern. MethodsA total of 82 patients with asthenospermia of spleen-kidney deficiency pattern in Shanghai Seventh People's Hospital were included. The patients were randomly divided into an observation group and a control group， with 41 patients in each group. The control group received oral administration of WuziYanzong pills combined with spleen-strengthening moxibustion. The dosage of Wuzi Yanzong pills was 1 bag each time， and it was taken twice a day. The spleen-strengthening moxibustion was carried out once a week. The observation group， on the other hand， took Jiuzi Huichun decoction orally combined with spleen-strengthening moxibustion. The Jiuzi Huichun Decoction was taken 200 mL each time， twice a day， with one dose in the morning and one in the evening. The spleen-strengthening moxibustion for the observation group was also performed once a week. The treatment course for both groups was 12 weeks， and they were followed up for an additional 12 weeks. During the treatment process，12 cases were either lost to follow-up or excluded. Eventually， 70 cases were available for evaluation，with 35 cases in the control group and 35 cases in the observation group. The pregnancy status of the patients' spouse within 6 months was recorded. The traditional Chinese medicine （TCM） syndrome scores of spleen-kidney deficiency pattern before and after treatment were evaluated. The semen volume，semen routine parameters，normal sperm morphology，sperm DNA fragmentation index，seminal plasma fructose，seminal plasma acid phosphatase， and seminal plasma α-glucosidase levels of the two groups were detected before and after treatment. In addition， the safety indicators related to liver and kidney functions of the two groups were detected before and after treatment. ResultsDuring the 6-month observation period， when compared with the situation before treatment in their respective groups，the semen volume of the observation group and the control group increased. In contrast， the sperm concentration，sperm motility，proportion of a+b-grade sperm，normal sperm morphology，seminal plasma fructose，seminal plasma acid phosphatase，seminal plasma α-Glucosidase，the proportion of a-grade sperm，linear sperm motility，linear sperm concentration， and linear sperm count all increased significantly（P<0.05）. At the same time， the sperm DNA fragmentation index and the TCM syndrome scores of the spleen-kidney deficiency pattern decreased significantly（P<0.05）. When the observation group was compared with the control group after treatment， the clinical efficacy of the observation group was better（Z=-2.276，P<0.05）. The pregnancy rate of the observation group's spouses was 14.3%，which was higher than the 2.9% of the control group. The sperm motility， the proportion of a+b-grade sperm，seminal plasma fructose，the proportion of a-grade sperm，normal sperm morphology，α-glucosidase， and linear sperm motility in the observation group were higher than those in the control group （P<0.05）. Moreover， the sperm DNA fragmentation index and the TCM syndrome scores of spleen-kidney deficiency pattern in the observation group were lower than those in the control group （P<0.01）. No serious adverse reactions occurred in the two groups，and no abnormalities were found in the safety indicators after treatment. ConclusionJiuzi Huichun decoction combined with spleen-strengthening moxibustion can enhance sperm viability and sperm concentration. It can also improve the TCM-related symptoms of asthenospermia of spleen-kidney deficiency pattern and sperm morphology. Additionally， it can reduce the sperm DNA fragmentation index and regulate the level of seminal plasma bioenzyme in patients with male asthenospermia infertility of spleen-kidney deficiency pattern. Therefore， it is worthy of further promotion and application in clinical practice.

Objective:To explore the value of blood lactic acid (BLA), procalcitonin (PCT), and total bilirubin (TBil) in the diagnosis and prognosis evaluation of patients with trauma complicated with sepsis.Methods:The clinical data of 151 patients with severe trauma admitted to the Department of Emergency Medicine, Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2019 to August 2023 were analyzed retrospectively. The patients were divided into the sepsis group (72 cases) and non-sepsis group (79 cases) according to the diagnosis. They were further divided into the death group (37 cases) and non-death group (114 cases) based on clinical outcomes. Clinical data were compared between groups. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of the above indicators, and Spearman correlation analysis was applied to evaluate the correlation between the indicators.Results:The levels of BLA, PCT, TBil, and Sequential Organ Failure Assessment (SOFA) score in the sepsis group were higher than those in the non-sepsis group (all P<0.05). The mortality rate of the sepsis group was significantly higher than that of the non-sepsis group, with a statistically significant difference [26/72(36.11%) vs 11/79(13.92%), χ 2=10.024, P=0.002]. The levels of BLA, PCT, TBil, and SOFA score in the death group were higher than those in the non-death group (all P<0.05). ROC curve analysis showed that the areas under the curve (AUC) of BLA, PCT, TBil, and their combination for diagnosing sepsis were 0.745, 0.826, 0.753, and 0.889 respectively; the sensitivity and specificity of the combined diagnosis of sepsis were 87.5% and 72.2%. The AUCs of BLA, PCT, TBil, and their combination for predicting the prognosis of sepsis were 0.644, 0.697, 0.614, and 0.713 respectively; the sensitivity and specificity of the combined prediction of sepsis prognosis were 64.9% and 71.1%. Among the 151 patients, the levels of BLA, PCT, TBil were positively correlated with SOFA score, with statistically significant differences ( r=0.3871, 0.4399, 0.4851, all P<0.001). Conclusions:BLA, PCT, and TBil levels have certain value in the early diagnosis and prognosis evaluation of patients with sepsis. The combined evaluation has the best efficacy and high guiding value in clinical practice.

Objective:To analyze the clinical features and diagnostic process of ring chromosome syndrome.Methods:Clinical data of 9 children with ring chromosome syndrome who were treated at the Children′s Medical Center of Peking University First Hospital from September 2009 to May 2025, were summarized and analyzed in a case series study. The data included clinical manifestations, types of epileptic seizures, genetic testing, treatment outcomes, and follow-up results, et al.Results:Among the 9 children with ring chromosome syndrome, there were 6 girls and 3 boys, including 4 children with ring chromosome 20 syndrome, 3 children with ring chromosome 14 syndrome, and 1 child each with ring chromosome 13 and 17 syndrome. All 9 children had de novo chromosomal variations. Among them, 3 children of ring chromosome 20 syndrome were mosaic, and the remaining 6 children were non-mosaic. All 9 children exhibited diverse clinical features, especially those with ring chromosome 20 syndrome, which presented with specific manifestations. The 4 children with ring chromosome 20 syndrome all had acute epileptic seizures as the initial symptom, with onset ages of 67, 39, 17, and 96 months, and all had focal seizures. One child with ring chromosome 20 syndrome had non-convulsive status epilepticus. Development of all 4 children with ring chromosome 20 syndrome was normal before seizure onset, but 3 children showed regression after onset. No physical deformities were observed in 4 children with ring chromosome 20 syndrome, and 2 children were misdiagnosed, 3 children underwent whole exome sequencing and copy number variation analysis in their families, with no abnormalities detected. All 4 children with ring chromosome 20 syndrome were diagnosed through chromosomal karyotype analysis, the intervals between onset and diagnosis were 2, 81, 19 and 13 months, respectively. Follow-up showed that epileptic seizures were not controlled in all 4 children with ring chromosome 20 syndrome. The other 5 children were characterized by developmental delay as the initial symptom, followed by epileptic seizures between 3 and 24 months of age. Developmental regression of the other 5 children did not occur after onset, 2 of them had microcephaly, and 3 had wide-set eyes. No misdiagnoses were reported in these 5 children, and the intervals between onset and diagnosis were 7, 3, 55, 3, and 106 months, respectively. Follow-up showed that epileptic seizures were controlled in these 5 children. Conclusions:Ring chromosome 20 syndrome typically manifest with epilepsy as the initial symptom and are refractory to drug treatment, their early development is entirely normal. Ring chromosome 13, 14, and 17 syndrome are characterized by developmental delay from an early age, followed by the onset of epileptic seizures, which are easily controlled. Conventional whole exome sequencing and copy number variation analysis in families rarely detect ring chromosome abnormalities. Early chromosomal karyotype analysis is essential for the diagnosis of ring chromosome syndrome.

Objective:To explore the genetic and clinical characteristics of epilepsy related with ATP6V1A gene heterozygous variants.Methods:A case series study was conducted. The clinical data of 10 children of epilepsy associated with ATP6V1A gene variants who were admitted to the Children′s Medical Center, Peking University First Hospital from January 2019 to December 2024 was collected. The characteristics of children′ gene variation, clinical phenotype, auxiliary examination results, treatment and prognosis were analyzed.Results:Among the 10 children, there were 4 boys and 6 girls. All 10 children with ATP6V1A gene variants were de novo heterozygous variants, including 1 case of mosaic variant. A total of 9 different variants were identified and 7 variants have not been reported previously. The age at epilepsy onset was 28 (9, 48) months. Five children experienced their first seizure as a fever induction. The types of epileptic seizures included focal seizures in 6 children, epileptic spasms in 5 children, tonic spasms and atonic seizures in 1 child respectively. Three children had 2 seizure types. Global developmental delays were exhibited in 8 children, 2 of whom manifested autism spectrum disorder phenotypes. Two children showed normal development. Electroencephalography revealed slowed background activity in 5 children. Interictal epileptiform discharges were recorded in 9 cases, including hypsarrhythmia, focal, multifocal or generalized discharges. Clinical seizures were captured in 4 children. Brain magnetic resonance imaging abnormalities were found in 4 children, including frontotemporal cortical dysplasia, prominent sulci, delayed myelination of white matter, dysplasia of the corpus callosum, bilateral ventricular enlargement, and cerebral atrophy. Five children were diagnosed with developmental and epileptic encephalopathy (DEE), and 4 of them were diagnosed with infantile epileptic spasms syndrome. At the last follow-up, the age was 78 (25, 120) months. Seizures were controlled in 6 children, while 4 children had uncontrolled seizures despite treatment with ≥3 anti-seizure medications. Conclusions:All children with ATP6V1A gene related epilepsy harbored de novo heterozygous missense variants, with few showing mosaic variants. Seizure onset age ranged widely from the neonatal period to childhood. The predominant seizure types were focal seizures and epileptic spasms. The phenotypic spectrum may exhibit DEE, while a minority maintain normal development.

Objective:To summarize the clinical phenotype and genetic features of patients with relapsing encephalopathy with cerebellar ataxia (RECA) caused by ATP1A3 gene R756 variants. Methods:A retrospective analysis was performed on patients carrying the ATP1A3 gene R756 variants, identified by whole-exome sequencing of family members, at Capital Center for Children′s Health, Capital Medical University and Children's Medical Center, Peking University First Hospital from August 2005 to February 2024. Their clinical, laboratory, neuroimaging, electrophysiological and genetic characteristics were summarized. Results:A total of 13 RECA patients were enrolled in this study, including 8 males and 5 females. The age of onset was 8 months to 5 years, with a median age of onset of 18 months. All of 13 patients presented paroxysmal episodes of neurological decompensations triggered by fever and residual symptoms following the acute phase. During acute attack stage, ataxia was observed in all 13 cases, muscle weakness in 12 cases, dysarthria in 12 cases, altered consciousness in 10 cases, dysphagia in 10 cases, dystonic episodes in 4 cases, abnormal eye movement in 2 cases, choreoathetosis in 2 cases, and epileptic seizures in 1 case. All 13 patients had residual symptoms during the nonparoxysmal period, of whom 9 patients had ataxia, 9 patients had dysarthria, 4 patients had dystonia, 3 patients had cognitive disorders, and 1 patient had epileptic seizures. All 13 cases had ATP1A3 missense variants, and variant c.2266C>T/p.R756C was found in 6 cases, c.2267G>A/p.R756H in 5 cases, and c.2267G>T/p.R756L in 2 cases. Nine cases carried de novo variants, 4 with inherited variants. Conclusions:RECA caused by variants of ATP1A3 in residue 756 typically presents with an acute onset during infancy or early childhood, precipitated by febrile episodes and characterized by recurrent episodes of ataxia, with bulbar paralysis, muscle weakness and altered consciousness. Recurrence is common, and the most common persistent symptoms are cerebellar ataxia and dysarthria. A few patients have cognitive impairment. Three types of ATP1A3 gene variants R756C, R756H and R756L are related with RECA, and R756C is the most common variant.
