Due to its high sensitivity and non-destructive nature, Raman spectroscopy has become an essential analytical tool in biopharmaceutical analysis and drug development. Despite of the computational demands, data requirements, or ethical considerations, artificial intelligence (AI) and particularly deep learning algorithms has further advanced Raman spectroscopy by enhancing data processing, feature extraction, and model optimization, which not only improves the accuracy and efficiency of Raman spectroscopy detection, but also greatly expands its range of application. AI-guided Raman spectroscopy has numerous applications in biomedicine, including characterizing drug structures, analyzing drug forms, controlling drug quality, identifying components, and studying drug-biomolecule interactions. AI-guided Raman spectroscopy has also revolutionized biomedical research and clinical diagnostics, particularly in disease early diagnosis and treatment optimization. Therefore, AI methods are crucial to advancing Raman spectroscopy in biopharmaceutical research and clinical diagnostics, offering new perspectives and tools for disease treatment and pharmaceutical process control. In summary, integrating AI and Raman spectroscopy in biomedicine has significantly improved analytical capabilities, offering innovative approaches for research and clinical applications.

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 therapeutic effect of hypericin on acute pancreatitis(AP)in mice and its effect on NLRP3 inflammasome signaling pathway.Methods The AP model in mice was established with caerulein(CER).The mice were divided into the normal control group,the model group(AP group),the low-dose HY group(CER+HY 5 mg/kg group),the medium-dose HY group(CER+HY 10 mg/kg group)and the high-dose HY group(CER+HY 20 mg/kg group),with 10 mice in each group.The 266-6 mouse pancreatic acinar cancer cells were treated with cholecystokinin(CCK)and divided into the control group,the AP group,the CCK+HY 1 μmol/L group,the CCK+HY 2 μmol/L group and the CCK+HY 4 μmol/L group.The activities of amylase(AMS),lipase,trypsin and myeloperoxidase(MPO)in the serum of each group of mice,and levels of inflammatory factors interleukin(IL)-1β and tumor necrosis factor(TNF)-α were detected by enzyme-linked immunosorbent assay(ELISA).The expression of NOD-like receptor family protein 3(NLRP3)was detected by Western blot assay.The mRNA levels of NLRP3,caspase(Caspase)-1,IL-1β,TNF-α and IL-18 in pancreatic tissue of mice were detected by real-time quantitative PCR(q-PCR).The cell survival rate of cells in each group was detected by CCK8 method.The mRNA expression levels of NLRP3,Caspase-1 and IL-18 in each group of cells were detected by q-PCR.Results Compared with the normal control group,the levels of AMS,lipase,MPO,trypsin,IL-1β and TNF-α in serum of the model group,and the mRNA and protein expression levels of NLRP3,IL-1β,TNF-α,IL-18 and Caspase-1 in pancreatic tissue were increased(P＜0.01).Compared with the model group,the levels of AMS,IL-1β and TNF-α,the enzymatic activity of trypsin in serum,and the mRNA levels of IL-1β,TNF-α,IL-18 and Caspase-1 in pancreatic tissue were decreased in the low-,medium-and high-dose HY groups.The serum levels of lipase and MPO and the mRNA expression levels of NLRP3 in pancreatic tissue were decreased in the medium-and high-dose HY groups(P＜0.05).Compared with the AP group,the cell survival rates were increased in the CCK+HY 1 μmol/L group,the CCK+HY 2 μmol/L group and the CCK+HY 4 μmol/L group,and the mRNA levels of NLRP3,IL-18 and Caspase-1 were decreased in a dose-dependent manner(P＜0.05).Conclusion Hypericin can effectively treat AP in vivo and in vitro,and its therapeutic effect may be related to the regulation of NLRP3 inflammasome signaling pathway.

Objective:To understand the clinical application of magnesium sulfate injection in inpatients of the obstetrical department, and analyze retrospectively its rationality and existing problems.Methods:The clinical data of obstetric inpatients who used magnesium sulfate injection in the hospital information system of our hospital from September 2022 to January 2023 were collected. Based on the drug instructions, guidelines for the diagnosis and treatment of hypertensive disorders in pregnancy, domestic and foreign guidelines, and literature reports, the rationality of magnesium sulfate injection in terms of obstetric medication indications, dosage and administration, and treatment course was evaluated.Results:A total of 303 obstetric patients were included in the use of magnesium sulfate injection, with an age of 32 (ranging from 18 to 44) years and a gestational age of 14 to 40 weeks. Among them, 33 cases were used for threatened abortion, 141 cases for threatened preterm birth, and 129 cases for the prevention of eclampsia attacks. Among the 303 patients, 134 cases (44.22%) had no indications for medication. Among them, 13 patients with threatened abortion were treated for fetal brain protection, and 20 patients with threatened abortion and 101 patients with threatened preterm birth were treated for preventing miscarriage by uterine contraction inhibition. There were 118 cases (38.94%) with inappropriate administration methods, mainly due to inappropriate usage and dosage, as well as overly long treatment courses. Of them, 26 cases (22.03%, 26/118) used for brain protectors of premature fetuses were not given loading doses, 15 (12.71%, 15/118) cases had a total medication duration of more than 48 hours, 76 cases (64.41%, 76/118) used for the prevention of eclampsia were not given loading dose, and 1 case (0.85%, 1/118) received rapid infusion time of the loading dose more than 30 minutes. Among the 303 patients, 3 patients presented nausea and vomiting, constipation, and skin flushing, respectively.Conclusions:Nearly half of the magnesium sulfate injection used in obstetrics department in our hospital has inappropriate indications and over one-third has non-standard usage, dosage, and treatment courses. Clinicians should comprehensively assess the patient′s condition and strictly follow recommended methods in the guidelines and drug instructions for standardized use.
