OBJECTIVE To upgrade the drug traceability code management system for a pediatric hospital under the “payment by code” background， aiming to comprehensively enhance traceability integrity， efficiency， and compliance. METHODS Taking Xiamen Children’s Hospital as the implementation setting， a before-and-after control design was adopted to construct an intelligent drug traceability code management system through systematic upgrades involving the technology platform， core mechanisms， and coordination with medical insurance. Key interventions included： upgrading a traceability code management platform and designing a dynamic code pool； innovating differentiated traceability mechanisms for routine， split-dose， and special drugs； establishing a tiered early-warning and emergency response system； and constructing a data coordination and quality control system. The drug traceability code upload rate served as the primary outcome. Process indicators such as the root causes distribution of failed uploads and the duration of medication returns， and a comprehensive outcome （the number of insurance-flagged abnormal prescriptions） were also analyzed. The data between the baseline period （April 2025） and the observation period （June-August 2025） were compared and evaluated. RESULTS After the upgrade， the overall upload rate of drug traceability codes increased from 9.21% （baseline） to 99.86% （August 2025）. The upload rate of traceability codes in previously unmanaged areas， such as the inpatient pharmacy and pharmacy intravenous admixture services， soared from 0 to nearly 100%. The proportion of non-uploads due to system issues fell from 66.44% （June 2025） to 2.62% （August Additionally， the number of insurance-flagged） abnormal prescriptions dropped sharply from 2 275.00 in the first “payment by code” policy month （July 2025） to 212.00 by the end of the observation period （August 2025）， a 90.70% decrease. CONCLUSIONS The developed management system effectively addresses complex scenario challenges such as high-frequency drug splitting. It significantly enhances traceability code upload performance and ensures a high degree of compliance with medical insurance data requirements. These outcomes contribute to proactive risk mitigation against insurance claim denials and demonstrate a concurrent optimization of pharmacy operations.

Objective: To identify early clinical predictors associated with dysphagia and delayed swallowing recovery in patients with traumatic brain injury (TBI). Methods: In this retrospective study, we enrolled adult TBI patients admitted to the rehabilitation unit of a tertiary medical center between June 2019 and June 2023. Data on baseline characteristics, neurological status, imaging findings, and rehabilitation-related variables were collected. Swallowing function was assessed using two indicators: (1) nasogastric (NG) tube retention and (2) the Functional Oral Intake Scale (FOIS) scores at 1, 4, and 12 weeks post-injury. Regression analyses were conducted to identify predictors associated with dysphagia and swallowing recovery. Results: A total of 160 patients were included. At 1 week post-injury, longer intensive care unit (ICU) stay, poor initial sitting balance and use of sedative medication in ICU were associated with NG tube retention. At 4 weeks, lower initial Rancho Los Amigos Scale (RLAS) scores, immobility-related complications, longer hospitalization, and temporal lobe hematomas were associated with persistent NG tube dependence. By 12 weeks, older age, delayed ability to follow commands, and poor initial sitting balance remained associated with NG tube retention. FOIS outcomes were also associated with older age, delayed time to follow commands, impaired initial sitting balance, prolonged ICU stay, temporal lobe hematomas, lower initial RLAS scores, immobility-related complications, prolonged endotracheal tube placement and extended hospital stays. Conclusion Impaired cognitive status, poor physical function, immobility-related complications, and temporal lobe hematomas were key factors associated with dysphagia and delayed oral intake in individuals with TBI.

Background: Cerebral hypoxia-ischemia impairs brain development in extremely preterm infants and is associated with poor neurological outcomes. Near-infrared spectroscopy (NIRS) is a noninvasive continuous monitoring method for regional cerebral oxygen saturation (rcSO2).Purpose: This study evaluated the clinical feasibility and neurological impact of a neurocritical care bundle that incorporates prolonged multidisciplinary hemodynamic monitoring and a stepwise management algorithm. Methods: Preterm infants with a gestational age (GA) ≤28 weeks or birth weight (BW) ≤1,000 g were prospectively enrolled in a bundle group subjected to NIRS for rcSO2, electrical cardiometry for cardiac output, and daily brain and cardiac echography during the first 72 hours of life. Monitoring was repeated weekly in the first month and then monthly until discharge or the term-equivalent age (TEA) was reached. We implemented a stepwise management algorithm for treating cerebral hypoxia. The primary outcome was a composite of mortality and adverse neurological events (structural abnormalities or electroencephalogram-confirmed seizures) before discharge. The secondary outcomes were the physiological pattern of rcSO2 within the initial 72 hours and up to discharge or TEA. Results: Thirty preterm infants (GA, 27.1±2.0 weeks; BW, 830±225 g) were enrolled in the bundle group. The mean time-averaged rcSO2 (66.8%±10.3%) was not associated with GA or BW. However, postnatal age appeared to influence physiological rcSO2 changes, given that rcSO2 values were higher during the initial 72 hours than at subsequent intervals. Seven infants (23.3%) had poor outcomes and significantly lower time-averaged rcSO2 (51.1% [50.0%–65.2%] vs. 71.8% [67.1%–73.1%], P=0.002). Multivariate regression indicated that a lower rcSO2 was an independent risk factor, and a 65% threshold showed an optimal predictive value for poor outcomes. Conclusion The neurocritical care bundle helped identify preterm infants at risk of cerebral hypoxia, and lower rcSO2 was an independent risk factor for composite mortality and adverse neurological outcomes.

Occupational disease diagnostician (ODD) is the core technology professional who is responsible for occupational disease diagnosis and identification and the main inspection work for occupational medical examination. The implementation of regular assessment management for ODDs is a key component of standardized workforce management, which facilitates dynamic evaluation of professional competence, regulation of medical practice, and assurance of medical safety. Since January 2025, Guangdong Province has implemented regular assessment management for ODDs within its administrative region. The assessment adopts an integrated model consisting of three components including professional competency evaluation, performance appraisal, and professional ethics evaluation, with each assessment cycle lasting three years. ODDs who passed all three components are classified as qualified ODD, whereas those who failed to pass any one of the three components result in an unqualified assessment outcome. In the implementation of ODD regular assessment management, Guangdong Province has emphasized integrating assessment with quality evaluation, strengthening full-cycle supervision of ODDs′ professional conduct, optimizing assessment strategies for special groups of ODDs, and reinforcing the primary management responsibility of medical institutions. Meanwhile, ODDs′ professional competence, service quality, and professional integrity have been continuously promoted by adopting human-computer interactive assessments, information-based assessment management, and "elimination" mechanism.

ObjectiveTo investigate the optimal ratio of goat horn replacing antelope horn in Fufang Lingjiao Jiangya pills and the blood pressure-lowering mechanism of this medicine. MethodsThe blood pressure-lowering efficacy of Fufang Lingjiao Jiangya pills with varying proportions of goat horn replacing antelope horn was evaluated on spontaneous hypertensive rats （SHR）. In this experiment， 50 SHR rats were randomly grouped as follows： model （n=8）， captopril （0.01 g·kg^-1） （n=6）， low-dose blank Fufang Lingjiao Jiangya pills （0.342 g·kg^-1） （n=6）， high-dose blank Fufang Lingjiao Jiangya pills （0.684 g·kg^-1） （n=6）， low-dose antelope horn-containing Fufang Lingjiao Jiangya pills （0.378 g·kg^-1） （n=6）， high-dose antelope horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1） （n=6）， low-dose goat horn-containing Fufang Lingjiao Jiangya pills （0.378 g·kg^-1） （n=6）， and high-dose goat horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1） （n=6）. Additionally， 8 WKY rats were used as the normal group. Drugs were administered by gavage for 4 weeks while an equal volume of distilled water was administered for the normal and model groups. Blood pressure was measured before administration， 3 h post administration， and biweekly thereafter. In the experiment for Fufang Lingjiao Jiangya pills with goat horn replacing antelope horn in different proportions， 48 SHR rats were randomly grouped as follows： model， blank Fufang Lingjiao Jiangya pills （0.684 g·kg^-1）， antelope horn-containing Fufang Lingjiao Jiangya pills （0.756 g·kg^-1）， 2× goat horn-containing Fufang Lingjiao Jiangya pills （0.824 g·kg^-1）， 4× goat horn Fufang Lingjiao Jiangya pills （0.969 g·kg^-1）， and 6× goat horn Fufang Lingjiao Jiangya pills （1.112 g·kg^-1）. The normal group included 8 WKY rats， and the normal group and model group received an equal volume of distilled water. The treatment lasted for 2 weeks， and blood pressure was recorded at various time points （pre-administration， 3 h post administration， and on days 4， 7， 10， and 14 of administration）. Serum levels of angiotensin-converting enzyme （ACE）， angiotensin Ⅱ（Ang Ⅱ）， renin， and interleukin-6 （IL-6） were measured by enzyme-linked immunosorbent assay. Histopathological changes in the heart， kidney， and thoracic aorta were observed by hematoxylin-eosin staining. The protein levels of ACE2， angiotensin Ⅱ type 1 receptor （AT1R）， and angiotensinogen （AGT） in the kidney tissue were determined by Western blot， while the expression of nuclear factor （NF）-κB p65 and Toll-like receptor 4 （TLR4） in the thoracic aorta tissue was assessed by immunohistochemistry. ResultsCompared with the model group， all treatment groups showed lowered blood pressure （P<0.05， P<0.01）， and the 6× goat horn-containing Fufang Lingjiao Jiangya pills group showed consistent blood pressure-lowering effect with the antelope horn-containing Fufang Lingjiao Jiangya pills group. Compared with the normal group， the model group showed elevated serum levels of ACE， Ang Ⅱ， renin， and IL-6， while the elevations were declined in the Fufang Lingjiao Jiangya pills groups （P<0.05， P<0.01）. Pathological changes in the heart， kidney， and thoracic aorta were alleviated in all the treatment groups， with the 6× goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups exhibited the best effect. Western blot and immunohistochemistry results showed that all the treatment groups exhibited down-regulated protein levels of AT1R， AGT， NF-κB p65， and TLR4 and up-regulated protein levels of ACE2 （P<0.05， P<0.01） compared with model group， with the 6×goat horn- and antelope horn-containing Fufang Lingjiao Jiangya pills groups showcasing the best effect. ConclusionReplacing antelope horn with 6×goat horn in Fufang Lingjiao Jiangya pills can achieve consistent blood pressure-lowering effect with the original prescription. The prescription may exert the effect by inhibiting the renin-angiotensin-aldosterone system （RAAS） and TLR4/NF-κB signaling pathways.

ObjectiveTo investigate the role of paraventricular nucleus (PVN) corticotropin releasing hormone (CRH) neurons in chronic restraint stress (CRS)-induced anxiety-like behavior. And whether exercise relieves chronic restraint stress-induced anxiety through PVN CRH neurons. MethodsTwenty 8-week-old male C57BL/6J mice were randomly divided into control (Ctrl) group and chronic restraint stress (CRS) group. The open field test (OFT) and elevated plus maze (EPM) were used to evaluate anxiety-like behavior of the mice. Food intake was recorded after CRS. Immunofluorescence staining was used to label the expression of c-Fos expression in PVN and calculate the co-expression of c-Fos and CRH neurons. We used chemogenetic activation of PVN CRH neurons to observed the anxiety-like behavior. 8-week treadmill training (10-16 m/min, 60 min/d, 6 d/week) were used to explore the role of exercise in ameliorating CRS-induced anxiety behavior and how PVN CRH neurons involved in it. ResultsCompared with Ctrl group, CRS group exhibited significant anxiety-like behavior. In OFT, the mice in CRS groups spent less time in center area (P<0.001). In EPM, the time in open arm in CRS group were significantly decreased (P<0.001). Besides, food intake was also suppressed in CRS group compared with Ctrl group (P<0.05). Compared with Ctrl group, CRS significantly increase c-Fos expression in PVN and most of CRH neurons co-express c-Fos (P<0.001). Chemogenetic activation of PVN CRH neurons induced anxiety-like behavior (P<0.05) and inhibited feeding behavior (P<0.01). Exercise relieves chronic restraint stress-induced anxiety (P<0.001) and relieved the anorexia caused by chronic restraint stress (P<0.05). Aerobic exercise inhibited the CRS labeled c-Fos in PVN CRH neurons (P<0.001). Furthermore, ablation of PVN CRH neurons attenuated CRS induced anxiety-like behavior. ConclusionCRS activated PVN CRH neurons, induced anxiety-like behavior and reduced food intake. 8-week exercise attenuated CRS-induced anxiety-like behavior through inhibiting PVN CRH neuron. Ablation of CRH PVN neurons ameliorated CRS-induced anxiety-like behavior. These finding reveals a potential neural mechanism of exercise-relieving CRS-induced anxiety-like behavior. This provides a new idea and theoretical basis for the treatment of anxiety and related mental disorders.

Objective To study the effect of intra-aortic balloon pump(IABP)in the therapy of ST-segment-elevation myocardial infarction(STEMI)patients complicated with ventricular septal rupture(VSR).Methods A retrospective analysis was performed on 35 STEMI patients complicated with VSR.Those patients were admitted in Yan'an Hospital Affiliated to Kunming Medical University from January 2019 to June 2023.Patients were divided into the combine-treated group(20 cases)and the drug-treated group(15 cases)according to the therapeutic strategies.The combine-treated group received IABP implantation and drug therapy,and the drug-treated group only received drug therapy.The clinical characteristics,hemodynamic and cardiac function improvement and mortality were evaluated.Hemodynamic and cardiac function improvement were compared between the two groups.Results There were no statistically significant differences in age,male proportion and size of VSR between the two groups(P>0.05).In the combine-treated group,the average heart rate,the average arterial blood pressure,central venous pressure,the LVEF value of cardiac ultrasound,pleural effusion,B-Line of lung,the level of B-type natriuretic peptide(BNP),the level of serum creatinine and the level of serum lactic acid were improved at 72 h after IABP use(all P<0.05).All these indicators got worse in the drug-treated group.The mortality rate of the combine-treated group was markedly lower than that of the drug-treated group(P<0.05).The mortality rate of patients who received IABP implantation within 72 h after VSR was lower than that of patients who received IABP implantation beyond 72 h after VSR.Conclusion For patients with AMI complicated with VSR,implantation of IABP can significantly improve hemodynamics,cardiac function and reduce mortality.

OBJECTIVE To compare the effect of traditional swab sampling method on etiological surveillance of in-fectious diseases for large-scale object surfaces in hospitals and validate the samples processing method based on pre-wet anti-static fabric and modified polyethylene glycol(PEG)precipitation enrichment technology so as to im-prove the capability of early warning of infectious diseases and optimize the environmental surveillance program in the hospitals.METHODS The on-site surveillance was carried out for 8 times in 3 public hospitals(Shenzhen Longgang People's Hospital,the Second People's Hospital of Longgang and Longgang Maternal and Child Health Hospital)from May 2024 to Mar.2025.Totally 23 types of respiratory tract pathogens(18 types of viruses,5 type of pathogenic bacteria)and 6 types of gastrointestinal tract pathogens were simultaneously detected by means of fluorescent quantitative polymerase chain reaction(PCR);the actual isolation rates,etiological spectrum and cycle threshold(Ct)value were compared.The acrylic plate added with standards of different loads of H1NI influ-enza viruses was used as model for laboratory evaluation.The minimum detection limit,sensitivity and repeatabili-ty were observed and compared between the methods.RESULTS The minimum detection limit of both methods was 6.0 × 104 copies/ml,however,the positive rate of nucleic acid testing of the pre-wet fabric method was 100.00％(3/3),higher than 33.33％(1/3)of the swab method;when the low viral load was 6.0× 105 copies/ml,the average concentration of viral nucleic acid of the pre-wet fabric method(X-Ct=36.59)was higher,with the re-peatability(CV=0.99％,＜3.14％)better.The results of the on-site surveillances showed that the total isolation rates of pathogens of the pre-wet fabric method ranged between 42.84％and 64.27％,higher than between 10.71％and 21.43％of the swab method,with the isolated pathogens more abundant,the Ct value lower(P＜0.05).CONCLUSION The pre-wet fabric sampling enrichment method integrated with anti-static fabric sampling and PEG enrichment technology shows higher sensitivity and stability in the etiological surveillance of large-scale object surfaces,raising the isolation rate.

Objective:To evaluate the clinical value of peripheral blood monocyte subset analysis in the diagnosis and treatment of chronic myelomonocytic leukemia (CMML) .Method:We retrospectively enrolled 51 patients newly diagnosed with CMML at Guangdong Provincial People's Hospital between June 1, 2020, and December 31, 2024, according to the WHO 2022 diagnostic criteria. Twenty-three patients with other myeloid neoplasms (excluding CMML) and peripheral monocytosis (absolute count ≥0.5×10 9/L and percentage ≥10%) were included as the control group. All patients underwent bone marrow aspiration for examinations including bone marrow smears, biopsies, cytogenetics, and gene mutation analysis to establish a definitive diagnosis. Concurrently, flow cytometry was used to determine the proportions of peripheral blood monocyte subsets: classical (MO1, CD14 +CD16 -) , intermediate (MO2, CD14 +CD16 +) , and non-classical (MO3, CD14 lowCD16 +) . Differences between the groups were compared, and diagnostic efficacy was evaluated using receiver operating characteristic (ROC) curves. Result:Among the 51 CMML patients, the proportion of the peripheral blood MO1 subset was significantly higher than that in patients with other myeloid neoplasms ( P=0.027) , whereas there were no significant differences in the MO2 and MO3 subsets (all P>0.05) . Further analysis revealed that 43 (84.31%) of the CMML patients met the WHO diagnostic threshold for the MO1 subset (≥94%) , while the remaining 8 patients did not; 46 patients (90.20%) had MO3 subset proportions below the threshold proposed by Hudson (≤1.13%) , while the remaining 5 patients were above this threshold. In-depth analysis showed that among the 8 patients who did not meet the WHO criteria, 7 were experiencing inflammation. Similarly, all 5 patients who did not meet the Hudson criteria were in an inflammatory state. Subsequent ROC curve analysis of this cohort identified a cut-off value for the MO1 subset of 97.55% [Area Under the Curve (AUC) =0.661, P=0.027], which aligns with the WHO criteria. Conclusion:Peripheral blood monocyte subset analysis, particularly MO1 subset analysis, can effectively assist in CMML diagnosis, but exclusion of inflammatory conditions is required.

OBJECTIVE: To observe the clinical effect of internal heat acupuncture therapy for knee osteoarthritis of early to middle stages, and explore its influence on cartilage thickness. METHODS: A total of 44 patients with knee osteoarthritis of early to middle stages were treated with internal heat acupuncture therapy at ashi points (most of them are located at the subpatellar fat pad, both sides of the patellar ligament, the tendon of the quadriceps and the attachment of the medial and lateral collateral ligaments), once a week, a total of 4 weeks of treatment. Before and after treatment, after 3 months of treatment completion (in the follow-up), the visual analogue scale (VAS) score, Western Ontario and McMaster Universities osteoarthritis index (WOMAC) score, frequency of 30-second chair stand test (30sCST), cartilage thickness of femoral intercondylar and knee joint ultrasound score were compared, and the clinical effect was evaluated. RESULTS: After treatment, the VAS、WOMAC and knee joint ultrasound scores were reduced (P<0.05), frequency of 30sCST was increased (P<0.05) compared with those before treatment; in the follow-up, the VAS、WOMAC scores were reduced (P<0.05), frequency of 30sCST and cartilage thickness of femoral intercondylar were increased (P<0.05) compared with those before treatment. After treatment, the total effective rate was 93.2% (41/44), in the follow-up, the total effective rate was 95.5% (42/44). CONCLUSION Internal heat acupuncture therapy is effective in the treatment of knee osteoarthritis of early to middle stages, could relieve the pain, improve the joint function, and delay cartilage degeneration and disease progression.
