Autoimmune pancreatitis is a special type of chronic pancreatitis that can lead to abnormal pancreatic exocrine function in patients. Autoimmune pancreatitis comorbid with pancreatic exocrine insufficiency has a complex pathogenesis， and there is limited research on this topic， leading to the lack of understanding of such patients in clinical practice. This article introduces the epidemiology of autoimmune pancreatitis， briefly describes the pathogenesis of pancreatic exocrine insufficiency caused by autoimmune pancreatitis， and summarizes the various detection methods for pancreatic exocrine function， nutritional assessments， lifestyle management， and drug therapy， in order to strengthen the understanding of autoimmune pancreatitis comorbid with pancreatic exocrine insufficiency and improve the clinical diagnosis and treatment of pancreatic exocrine insufficiency.

As a novel iron-dependent form of cell death, ferroptosis is characterized by the excessive accumulation of phospholipids containing polyunsaturated fatty acids (PUFA) on the cell membrane and peroxidation. Lipid droplets are always in the dynamic transition of generation and decomposition, play a central role in regulating lipid metabolism, and are always in the dynamic transition of generation and decomposition. Lipid droplet metabolism is closely related to the occurrence of ferroptosis and plays an important role in the disease caused by ferroptosis. This review firstly focuses on the lipid droplet metabolism process and its effects on the storage and release of PUFA, and further elucidates the regulatory mechanism and key regulatory proteins of lipid drop metabolism on ferroptosis, in order to reveal the intrinsic relationship between lipid droplets and ferroptosis, and provide a new strategy for disease prevention and treatment.

This study aimed to investigate the prevalence and clinical characteristics of epilepsy in patients with patent foramen ovale (PFO) and the effect of PFO closure on seizures. Patients diagnosed with PFO were recruited and underwent brain magnetic resonance imaging, electrocardiography, transesophageal echocardiography, and transthoracic echocardiography with right ventriculography. In patients with epilepsy, electroencephalography was performed. A total of 110 patients completed the assessment. A chief complaint of chest tightness or palpitations was proportionately higher in patients aged<18 years, whereas headaches and seizures were higher in patients aged≥18 years ( χ2=4.69 ,P<0.05). Comorbid epilepsy was observed in 20.9% of patients with PFO. The age at admission in the epileptic group (14-66(27±14)years) was significantly lower than that in the non-epileptic group (16-81(38±21)years) and that in patients with headache as the chief complaint (16-68(39±12)years) ( t=3.29, P<0.05). The multivariate analysis found no risk factors related to the prognosis of epilepsy. The incidence of epilepsy was significantly higher in patients with PFO than in the general population.

Objective To evaluates the impact of early application of neuromuscular electrical stimulation(NMES)on muscle strength,clinical outcomes,and long-term quality of life improvements in patients with severe acute pancreatitis(SAP)complicated with acute respiratory distress syndrome(ARDS).Methods A total of 75 patients diagnosed with SAP and ARDS admitted in Department of Critical Care Medicine of our hospital from September 2022 to August 2023 were recruited and then randomly divided into NMES group(n=37)and control group(n=38).After 16 patients were excluded,including 8 died during treatment,3 discharged and 5 received palliative care,there were finally 29 patients in the NMES group and 30 in the control group.Within 48 h after ICU admission,the NMES group received NMES 1 h per day,for 7 d in addition to standard rehabilitation intervention.While,the control group were given conventional interventions for rehabilitation.Assessments at baseline and post-treatment included the incidence of ICU-acquired weakness(ICU-AW),Medical Research Council(MRC)score,duration of mechanical ventilation,lengths of ICU and total hospital stays,and activity,thickness and thickening fraction of the diaphragm.Mortality rates and Barthel index(BI)for self-care ability in 1,3 and 6 months after discharge were recorded for follow-up assessments.Results The NMES group had significantly lower incidence of ICU-AW(P＜0.05),higher upper and lower limb MRC scores and overall MRC score at ICU discharge(P＜0.05),shorter durations of mechanical ventilation,ICU stay,and total hospital stay when compared with the control group(P＜0.05).There was no statistical difference in the BI at 1 month post-discharge between the 2 groups,but the indexes at 3 and 6 months were notably higher in the NMES group than the control group(P＜0.05).No obvious differences were observed between the 2 groups in terms of diaphragm activity,thickness,or thickening scores at enrollment,ICU discharge,or hospital discharge,nor in mortality rates at 1,3,and 6 months after discharge.Conclusion Combined NMES and early rehabilitation therapy can improve muscle strength and reduce length of hospital stay in SAP patients complicated with ARDS,and may enhance long-term quality of life.However,it does not significantly affect diaphragm function or mortality rates.

Objective: Sialidosis type 2 has variants that are both catalytically inactive (severe), while sialidosis type 1 has at least one catalytically active (mild) variant. This study aimed to discuss the structural changes associated with these variants in a newly reported family carrying N-acetyl-α-neuraminidase-1 (NEU1) variants and explore the clinical characteristics of different combinations of variants in sialidosis type 1. Methods: First, whole-exome sequencing and detailed clinical examinations were performed on the family. Second, structural analyses, including assessments of energy, flexibility and polar contacts, were conducted for several NEU1 variants, and a sialidase activity assay was performed. Third, previous NEU1 variants were systematically reviewed, and the clinical characteristics of patients in the severe-mild and mild-mild groups with sialidosis type 1 were analyzed. Results: We report a novel family with sialidosis type 1 and the compound heterozygous variants S182G and V143E. The newly identified V143E variant was predicted to be a mild variant through structural analysis and was confirmed by a sialidase activity assay. Cherry-red spots were more prevalent in the severe-mild group, and ataxia was more common in the mild-mild group. Impaired cognition was found only in the severe-mild group. Moreover, patients with cherry-red spots and abnormal electroencephalographies and visual evoked potentials had a relatively early age of onset, whereas patients with myoclonus had a late onset. Conclusion Changes in flexibility and local polar contacts may be indicators of NEU1 pathogenicity. Sialidosis type 1 can be divided into two subgroups according to the variant combinations, and patients with these two subtypes have different clinical characteristics.

This study explored the medication rules of Chinese herbal compound prescriptions for the treatment of angina based on the Chinese herbal compound patents in the patent database of the China National Intellectual Property Administration. The data of eligible Chinese herbal compound patents for the treatment of angina were collected from the patent database of the China National Intellectual Property Administration from database inception to November 10, 2022, and subjected to data modeling, analysis of main syndromes, medication frequency analysis, cluster analysis, association rule analysis, and data visualization by using Excel 2021, IBM SPSS Statistics 26.0, IBM SPSS Modeler 18.0, Cytoscape 3.9.1, and Rstudio R 4.2.2.2 to explore the medication rules for angina. The study included 636 pieces of patent data for angina that met the inclusion criteria, involving 815 drugs, with a total frequency of 6 586. The most common main syndromes were blood stasis obstructing the heart syndrome(222, 34.91%) and Qi deficiency and blood stasis syndrome(112, 17.61%). The top 10 most frequently used drugs were Salviae Miltiorrhizae Radix et Rhizoma, Chuanxiong Rhizoma, Notoginseng Radix et Rhizoma, Astragali Radix, Angelicae Sinensis Radix, Carthami Flos, Glycyrrhizae Radix et Rhizoma, Ginseng Radix et Rhizoma, Borneolum Syntheticum, and Corydalis Rhizoma. High-frequency drugs included blood-activating and stasis-resolving drugs(1 197, 18.17%) and deficiency-tonifying drugs(809, 12.28%). Cluster analysis identified eight drug combinations, including five new prescriptions suitable for clinical use and new drug development, and three drug pairs. The core drug combination of Salviae Miltiorrhizae Radix et Rhizoma-Chuanxiong Rhizoma-Carthami Flos was identified through the complex co-occurrence network analysis of Chinese medicines. Association rule analysis yielded a total of 17 rules, including 13 drug pairs and 4 tripartite combinations. Common drug pairs included Salviae Miltiorrhizae Radix et Rhizoma-Chuanxiong Rhizoma(support degree 25.79%, confidence coefficient 69.49%, lift 1.30) and Salviae Miltiorrhizae Radix et Rhizoma-Notoginseng Radix et Rhizoma(support degree 22.01%, confidence coefficient 61.95%, lift 1.16). Common tripartite combinations included Salviae Miltiorrhizae Radix et Rhizoma-Chuanxiong Rhizoma-Astragali Radix(support degree 10.85%, confidence coefficient 73.40%, lift 1.37) and Salviae Miltiorrhizae Radix et Rhizoma-Chuanxiong Rhizoma-Notoginseng Radix et Rhizoma(support degree 10.69%, confidence coefficient 79.07%, lift 1.48). The results showed that the underlying pathogenesis of angina involved blood stasis obstructing the heart and Qi deficiency and blood stasis. The overall nature of the disease was characterized as asthenia in origin and sthenia in superficiality. In the prescription formulation, blood-activating and stasis-resolving drugs, such as Salviae Miltiorrhizae Radix et Rhizoma, Chuanxiong Rhizoma, and Carthami Flos were often used to resolve the excess manifestation, which were combined with tonifying drugs such as Astragali Radix, Angelicae Sinensis Radix, Glycyrrhizae Radix et Rhizoma, and Ginseng Radix et Rhizoma to reinforce the deficiency. The syndrome, pathogenesis, disease nature, and medication were consistent with clinical practice. Additionally, the new compound prescriptions and drug combinations derived from the multiple data mining in this study could provide references and insights for the clinical diagnosis and treatment of angina and the development of new drugs.

OBJECTIVE: To validate the 2016 ISGPS definition and grading scheme and investigate whether it segregates into distinct subclasses. METHODS: A total of 522 patients undergone pancreaticoduodenectomy in two pancreatic centers were reviewed. The 2016 ISGPS scheme was validated by comparing clinical and economic outcomes between different ISGPS grades. B-POPF were divided into 2 subgroups as B1(without invasive procedures) and B2(with invasive procedures) then outcomes were analyzed across the subgroups. RESULTS: Biochemical leak(BL) did not differ from the non-fistula condition in all outcomes except postoperative hospital stay and cost. Non-fistula/BL,B-POPF and C-POPF condition differed significantly in terms of all clinical and economic outcomes except 30-day readmission rate.B1 differ from B2 subgroup greatly in terms of most critical terms of outcomes such as hemorrhage(15.2% vs. 34.3%,P=0.045),biliary fistula(13.0% vs 34.3%,P=0.023),postoperative hospital stay(32.0 d vs. 39.0 d,P=0.011). CONCLUSION: The present study has confirmed the effectiveness of the 2016 ISGPS definition and grading scheme in identifying three conditions that differ in terms of clinical and economic outcomes. Subclassification of B-POPF according to whether invasive procedures has been used has potential implications for accurate reporting and performance evaluation.

Phase Ⅰ clinical trials are the preliminary tests of clinical pharmacology and human safety evaluation.Majority of the subjects in phase Ⅰ clinical trials are healthy subjects.Besides,there are only a few number of healthy subjects included in one trial.Thus the data requires better accuracy and responsibility.If the subjects do not take medicine appropriately,it will directly affect the results and fail to provide accurate reference for the coming phase Ⅱ,Ⅲ clinical trial.Therefore subject medication is one of the key steps in the conduct of phase Ⅰ clinical trial.This article summarizes and discusses the key steps for oral,injection,inhalation and other delivery methods,to make sure the scientificity,accuracy and objectivity of the test results.This will also ensure the smooth development of late-stage clinical trials.

Objective To investigate the ability of targeting in vitro breast carcinoma and photoacoustic-mediate apoptosis of breast carcinoma of the nanoparticle probe loaded with Fe3O4 and observe its consequence of photoacoustic imaging in vitro.Methods The polymeric multifunctional nanoparticles probe that was loaded with Fe3O4 and connected with Herceptin targeting breast carcinoma was prepared in the use of double emulsion method and carbodiimide method.General physical property,the condition of Herceptin connected with nanoparticles and the ability of targeting of the probe were tested.The different concentration of nanoparticles was imaged by photoacoustic.The inhibiting effect of targeting nanoparticles on breast carcinoma cells was evaluated in vitro.Results The targeting polymeric multifunctional nanoparticles probes loaded with Fe3O,were prepared successfully with average particle diameter of (235.4± 53.75)nm and Zeta potential (-13.4 ± 4.7)mV.Fe3O4 particles dispersed on the shell of the probes.Antibody Hereeptin was successfully connected with the surface of the nanoprobes.There were massive targeting nanoprobes surround the breast carcinoma cell strains SKBR3 in the targeting group in vitro.The photoascoustic signal of the nanoprobes enhanced with the increase of Fe3O4 concentration in photoacoustic experiment in vitro.The apoptotic rate of breast carcinoma increased after the laser irradiation in the cell inhibition experiment in vitro.That proved the obvious inhibition of breast carcinoma cells was caused by photothermal effect of the prepared nanoprobes.Conclusions The prepared polymeric multifunctional nanoparticles probe that was loaded with Fe3O4 and connected with Herceptin targeting breast carcinoma can be used as a photoacoustic contrast agent,which can inhibit the proliferation of breast carcinoma by targeting photoacoustic therapy.
