OBJECTIVE To construct a dual-verification system integrating image pre-screening and Raman spectroscopy for inpatient pharmacy unit-dose dispensing in response to the issue of recognition blind spots for drugs of “same appearance but different spectrum” by drug inspection machines. METHODS An image feature and Raman spectroscopy database， covering 296 oral medications， were established. Spectral matching was performed using a cosine similarity algorithm （decision threshold 0.95）. A dual-verification system of “image pre-screening and Raman spectroscopy confirmation” was designed， and a self-controlled before-and-after study was conducted across 5 clinical wards. RESULTS The system achieved a mean recognition accuracy of 99.2% for all medications in the database， with 100% accurate identification of representative “same-appearance but different-spectrum” drugs. The average verification time per-unit in the experimental group （image recognition+Raman spectroscopy confirmation and verification） was reduced by 31.5%-43.3%， compared with the control group （image recognition+manual visual comparison with actual objects）（ P ＜0.001）. Nurses’ satisfaction scores in the dimensions of operational convenience， identification efficiency， verification confidence， and psychological stress relief in the experimental group were all significantly superior to those of the control group （ P ＜0.01）. CONCLUSIONS The dual-verification system of “image pre-screening and Raman spectroscopy confirmation” effectively overcomes the technical limitations of conventional machine vision. It enhances work efficiency and staff satisfaction while ensuring medication safety.

Objective To explore the effect of early weight-bearing functional exercise on the postoperative function and satisfaction of patients with anterior talofibular ligament rupture.Methods Sixty patients with anterior talofibular ligament rupture admitted to Nanchang Hongdu Hospital of Traditional Chinese Medicine from June 2022 to June 2024 were included.According to the random number table method,the patients were divided into conventional group and early weight-bearing group,with 30 cases in each group.The American Orthopedic Foot and Ankle Society ankle-hindfoot scale(AOFAS-AHS)scores,Cumberland ankle instability tool(CAIT)scores,joint position sense active(JPSA)and joint position sense passive(JPSP)of ankle joint before and after the operation,and postoperative satisfaction of two groups of patients were compared.Results Six months after the operation,the AOFAS-AHS scores and CAIT scores of two groups were significantly higher than those before the operation,and the JPSA and JPSP were significantly lower than those before the operation(P＜0.05).The AOFAS-AHS score and CAIT score of patients of early weight-bearing group were significantly higher than those of conventional group,while the JPSA and JPSP were significantly lower than those of conventional group(P＜0.05).The satisfaction rate of patients of early weight-bearing group was significantly higher than that of conventional group(76.6％vs.66.6％,x2=6.205,P＜0.001).Conclusion Early weight-bearing functional exercise can improve the postoperative function of patients with anterior talofibular ligament rupture and enhance their postoperative satisfaction.

Objective To explore the clinical characteristics and treatment methods of female primary enteric adenocarcinoma of the urethra.Methods The diagnosis and treatment of one case were reported.The origin,etiology,imaging findings,diagnosis,treatment,and prognosis were discussed in combination with relevant literature.Results The patient is a 61-year-old female,visited our hospital due to vaginal odor complicated with urethral bleeding for 2 months,and was diagnosed with urethral adenocarcinoma after examination.She underwent partial urethral resection,urethral meatus shaping and temporary bladder fistula surgery,with negative resection margins.However,local recurrence occurred 7 months after surgery.The patient was readmitted for a second time,undergoing laparoscopic total urethral resection,anterior vaginal wall resection,bladder neck resection,and permanent bladder fistulation,followed by chemotherapy.At the 19th month after the first surgery,the patient was admitted due to tumor recurrence,and the third surgery consisted of total bladder and uterus resection,ileal neobladder,and perineal closure.Postoperative pathology indicated urethral adenocarcinoma originating from the intestines.During the 39-month follow-up,the tumor recurred twice.No recurrence or metastasis was observed after the final total pelvic exenteration.Conclusion Enteric adenocarcinoma of the urethra is extremely rare.Comprehensive treatment including surgery,radiotherapy,and chemotherapy may prolong survival,but the overall prognosis is poor,requiring long-term follow-up.

Disruption of the intestinal mucosal barrier caused by gut dysbiosis and metabolic imbalance is the underlying pathology of inflammatory bowel disease (IBD). Traditional Chinese medicine Wuji Wan (WJW) is commonly used to treat digestive system disorders and showed therapeutic potential for IBD. In this interdisciplinary study, we aim to investigate the pharmacological effects of WJW against experimental colitis by combining functional metabolomics and gut-microbiota sequencing techniques. Treatment with WJW altered the profile of the intestinal microbiota and notably increased the abundance of Lactobacillus, thereby facilitating the conversion of tryptophan into indole-3-acetic acid (IAA) and indoleacrylic acid (IA). These indole derivatives activated the aryl hydrocarbon receptor (AhR) pathway, which reduced colonic inflammation and restored the expression of intestinal barrier proteins. Interestingly, the beneficial effects of WJW on gut barrier function improvement and tryptophan metabolism were disappeared in the absence of gut microbiota. Finally, pre-treatment with the AhR antagonist CH-223191 confirmed the essential role of IAA-mediated AhR activation in the therapeutic effects of WJW. Overall, WJW enhanced intestinal barrier function and reduced colonic inflammation in a murine colitis model by modulating Lactobacillus-IAA-AhR signaling pathway. This study provides novel insights into colitis pathogenesis and presents an effective therapeutic and preventive approach against IBD.

Objective:To analyze the clinical characteristics, RAN-binding protein 2 ( RANBP2) gene variations, and prognosis in Chinese acute necrotizing encephalopathy (ANE) patients. Methods:A retrospective analysis of ANE cases registered in the Peking Union Medical College Hospital Encephalitis Registry System from 2022 to 2024, involving patients from Peking Union Medical College Hospital and other hospitals, was conducted. A descriptive study was performed on the clinical characteristics, treatments and prognosis, cerebrospinal fluid examination results, and imaging findings of these patients based on adjusted ANE diagnostic criteria. Whole-exome sequencing technology was used to detect gene mutations in these patients.Results:A total of 18 ANE cases were included, ranged in age from 2 to 72 [20(5, 43)] years. The male-to-female ratio was 4∶5. All patients were found with precipitating infections including COVID-19, influenza A virus and Mycoplasma pneumoniae infections. All patients presented with fever, with varying degrees of consciousness disturbance observed in 16 cases, and seizures in 10 cases. All patients underwent lumbar puncture, with normal or mildly elevated white cell counts [3(2, 13)×10 6/L] and mildly to moderately elevated protein levels [1.90(0.92, 4.65) g/L]. A total of 6 patients were found with extremely elevated interleukin-6 level [950(164, 2 000) pg/ml] in cerebrospinal fluid. Bilateral symmetric thalamic lesions were typical imaging features of ANE, while involvement of other areas such as cortical and subcortical white matter, brainstem, and cerebellum was also observed. A total of 14 patients performed genetic tests while 4 patients were identified with RANBP2 gene mutations (c.1754C>T in 3 cases, c.1966A>G in 1 case). All patients received immunotherapy, and 7 patients died at discharge while other patients presented with neurological sequelae of varying degrees. Conclusions:ANE is a rare and severe parainfectious encephalopathy that can occur in both children and adults. Clinically, it is characterized by rapidly progressing encephalopathy following systematic infection, with bilateral symmetric thalamic lesions. The detection of RANBP2 gene mutations could help make the diagnosis.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective:To investigate the operation opportunity for vascular rings in infants and assess the impact of prenatal and postnatal integrated management strategies on treatment outcomes.Methods:A retrospective analysis was conducted on the clinical data of 75 infants with vascular rings who underwent surgical treatment at the Third Affiliated Hospital of Zhengzhou University from January 2016 to December 2023. Among them, 54 were males and 21 were females, with a median age at surgery of 1.7 (0.7-6.9) months and a median weight of 5.3 (3.5-8.0) kg. Vascular rings malformation was diagnosed by real-time three-dimensional color doppler echocardiography during pregnancy in 51 cases. Preoperatively, 28 cases presented with respiratory or digestive system-related symptoms, and 26 cases had a history of hospitalization due to related symptoms. All patients underwent preoperative cardiac CTA+ CTVE and three-dimensional reconstruction examinations, and 56 cases showed varying degrees of airway compression and stenosis on imaging. Among them, 10 patients presented with preoperative stridor and respiratory distress; fiberoptic bronchoscopy performed after anesthesia induction confirmed significant tracheal compression/stenosis. One patient was ventilator-dependent preoperatively, and bronchoscopy revealed main bronchomalacia. The cohort included: Complete vascular rings (62 cases of double aortic arch, 10 cases of right aortic arch with aberrant left subclavian artery and left-sided ductus arteriosus/ligamentum) and incomplete vascular rings (3 cases of pulmonary artery sling). Additionally, 5 cases had associated Kommerell’s diverticulum, and 12 had intracardiac malformation. All patients successfully completed surgery, and those with intracardiac malformation underwent extracorporeal circulation and primary radical surgery concurrently. Based on prenatal diagnosis and implementation of prenatal and postnatal integrated management, patients were divided into an observation group (prenatal and postnatal integrated management group) and a control group (postnatally diagnosed group). The perioperative data of the two groups were compared to analyze the surgical outcomes and the advantages of prenatal and postnatal integrated treatment.Results:All 75 patients successfully completed surgery. Preoperatively, 56 cases (74.66%) presented with varying degrees of tracheal stenosis. Except for 1 case that died after abandoning treatment and 1 case that underwent tracheal surgery due to repeated failed ventilator weaning, all other patients were successfully discharged from the hospital. The overall mortality rate was 1.33%, and the rate of tracheal surgery was 1.35%. The age and weight at surgery in the observation group were lower than those in the control group ( P<0.05), and the proportion of preoperative hospitalization history was lower in the observation group ( P<0.05). No significant differences were observed between the two groups in terms of tracheal compression and stenosis, postoperative monitoring time, operation time, ventilator time, and risk of postoperative complications ( P>0.05). Conclusion:Tracheal stenosis is a common complication in children with vascular rings. Early surgical intervention is recommended for complete vascular rings and pulmonary artery slings (as an incomplete ring). Timely prenatal diagnosis of vascular ring anomalies combined with the implementation of an integrated prenatal-postnatal management strategy can significantly reduce the risk of preoperative hospitalization due to related symptoms and may lower the risk of subsequent tracheal surgery, potentially improving long-term prognosis.

The transcription factor HOXB13 plays crucial roles in cancer development. HOXB13 is abnormally expressed in most cancers, which makes it a valuable therapeutic target for cancer therapy. The level of HOXB13 differs significantly between healthy and cancer tissues, which indicates that the level of HOXB13 is closely related to carcinogenesis. The regulatory network mediated by HOXB13 in cancer proliferation, metastasis, and invasion has been systematically investigated. Moreover, HOXB13 variants play distinct roles in different cancers and populations. By understanding the molecular mechanisms and mutation features of HOXB13, we provide a comprehensive overview of carcinogenesis networks dependent on HOXB13. Finally, we discuss advancements in anticancer therapy targeting HOXB13 and the roles of HOXB13 in drug resistance to molecular-targeted therapies, which serves as a foundation for developing HOXB13-targeted drugs for clinical diagnosis and cancer therapies.
