As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Nitrogen dioxide(NO 2)is a prevalent air pollutant that poses significant threats to the environment and human health,emphasizing the urgent need for high-performance NO 2 sensors for effective environmental monitoring at room temperature.Sensors based on metal halide perovskites have emerged as promising candidates for gas detection at room temperature,but their long-term stability remains a major challenge.In this study,a methylamine thiocyanate(MT)-doped FA 0.8Cs 0.2PbI 2Br(PVK)gas sensor(MT-PVK)was prepared using a simple one-step spin-coating method and ethyl acetate(EA)anti-solvent extraction technique.The crystalline structure,chemical composition,and particle morphology of the MT-PVK thin film were characterized.The MT-PVK thin film was then utilized as a gas sensor for NO 2 detection at room temperature.The results demonstrated that the sensor exhibited outstanding selectivity and reversibility at low concentrations of NO 2 gas,with a detection limit as low as 33 ppb(10-9,nL/L).For 10 ppm(10-6,μL/L)NO 2,the sensor showed rapid response and recovery time of only 1.6 s and 27 s,outperforming most traditional metal oxide NO 2 sensors.Furthermore,compared to the original PVK,the MT molecules significantly enhanced the structural and sensing stability of the MT-PVK sensor under high humidity conditions(55%±5%).These findings suggested that MT-doped FA 0.8Cs 0.2PbI 2Br perovskite gas sensors offered a promising pathway for the development of rapid-response gas sensing technologies suitable for room temperature operation.

Objective： The aim of this study is to explore the predictive value of biparametric magnetic resonance imaging(bpMRI)for pelvic lymph node metastasis in prostate cancer patients with PSA≤20 μg/L and establish a nomogram. Methods： The imaging data and clinical data of 363 patients undergoing radical prostatectomy and pelvic lymph node dissection in the First Affiliated Hospital of Nanjing Medical University from July 2018 to December 2023 were retrospectively analyzed. Univariate analysis and multivariate logistic regression were used to screen independent risk factors for pelvic lymph node metastasis in prostate cancer, and a nomogram of the clinical prediction model was established. Calibration curves were drawn to evaluate the accuracy of the model. Results： Multivariate logistic regression analysis showed extrocapusular extension (OR=8.08,95%CI=2.62－24.97, P<0.01), enlargement of pelvic lymph nodes (OR=4.45,95%CI=1.16－17.11,P=0.030), and biopsy ISUP grade(OR=1.97,95%CI=1.12－3.46, P=0.018)were independent risk factors for pelvic lymph node metastasis. The C-index of the prediction model was 0.834, which indicated that the model had a good prediction ability. The actual value of the model calibration curve and the prediction probability of the model fitted well, indicating that the model had a good accuracy. Further analysis of DCA curve showed that the model had good clinical application value when the risk threshold ranged from 0.05 to 0.70.Conclusion： For prostate cancer patients with PSA≤20 μg/L, bpMRI has a good predictive value for the pelvic lymph node metastasis of prostate cancer with extrocapusular extension, enlargement of pelvic lymph nodes and ISUP grade≥4.

In the century-long evolution of insulin pharmaceuticals, each transformative advancement in this drug class has been closely tied to the ability to obtain new insulin isoforms for research. Despite this, the recently discovered naturally occurring isoforms of glycosylated human insulin have remained largely unattainable for proper characterization. Herein, we demonstrate for the first time that total chemical synthesis can be used to generate all isoforms. This achievement required maintaining the correct positions of the interchain disulfide bonds while effectively removing protecting groups on complex glycans. Notably, the availability of seven glycoforms reveals the important effects of natural sialylated glycans in suppressing insulin self-association and enhancing its solubility, surpassing the performance of currently employed rapid-acting insulin drugs. This work not only offers a readily adaptable platform for exploring natural O-glycosylation in other therapeutic proteins and peptides but also lays the groundwork for further research into harnessing natural glycosylation for therapeutic applications.

Objective:To assess the efficacy and safety profile of antaitasvir phosphate combined with yiqibuvir in the treatment of chronic hepatitis C (CHC) of various genotypes, without cirrhosis or with compensated cirrhosis.Methods:394 cases with CHC from 22 centers were collected from October 2021 to April 2023. They were randomly assigned to receive either the experimental drugs (antaitasvir phosphate 100 mg+yiqibuvir 600 mg) or placebo treatment in a 3∶1 ratio. The patients were administered drugs once a day for 12 consecutive weeks, and then followed up for 24 weeks after treatment cessation. All subjects were unblinded at the four-week follow-up following drug discontinuation, with the experimental drug group continuing to complete subsequent post-discontinuation follow-up. The placebo group was switched to receive the experimental drugs for a repeated 12-week treatment period and followed up for another 24 weeks after discontinuation of the drug (placebo delayed treatment phase).The sustained virologic response rate (SVR12) was observed for subjects in the double-blind phase and the placebo delayed-treatment phase at 12 weeks after treatment cessation.Virological resistance analysis was performed on subjects who failed treatment. The primary efficacy endpoint was SVR12. The number and percentage of subjects who achieved "HCV RNA

Objective:To study the clinical manifestations and genetic characteristics of neonatal-onset primary mitochondrial disease (PMD) caused by nuclear gene mutations.Methods:From May 2020 to March 2022, the clinical data, genetic results and follow-up information of neonates with PMD admitted to the Department of Neonatology of our two hospitals were retrospectively analyzed.Results:A total of 4 patients were enrolled, all with hyperlactatemia and metabolic acidosis. In case 1, the fetal cranial MRI showed agenesis of corpus callosum. In case 2, echocardiography after birth indicated hypertrophic cardiomyopathy. Whole exome sequencing found the following mutations: EARS2 nuclear gene c.1294C>T and c.971G>T variants, COA6 nuclear gene c.411_412insAAAG variant, ACAD9 nuclear gene c.1278+1G>A and c.895A>T variants, FOXRED1 nuclear gene c.1054C>T and c.3dup variants. Mitochondrial second-generation sequencing and multiplex ligation-dependent probe amplification showed no abnormalities. Cases 1 and 3 died during the neonatal period. Case 2 died at 2-year-and-2-month of age. Case 4 was followed up to 1 year of age with developmental delay.Conclusions:The main phenotypes of neonatal-onset PMD caused by nuclear gene mutations are hyperlactatemia, refractory metabolic acidosis and cardiomyopathy, which have a poor prognosis. Proactive genetic tests are helpful for early diagnosis.

Objective:To explore the seizure-onset intracranial electroencephalogram patterns in mesial temporal lobe epilepsy (MTLE) by stereo-electroencephalography (SEEG).Methods:The clinical data of 16 patients with focal epilepsy admitted to Epilepsy Center, Shanghai Deji Hospital from March 2017 to December 2019 were retrospectively analyzed. Tonic discharge was taken as sign of the initial period; transition period from the interictal period to the initial period was named as the preictal period, characterized by clonic discharge that was different from the interictal period. The initial and preictal discharge patterns were described, and their corresponding relationship were studied; at the same time, the spatial distribution and synchrony of the discharges at initial and preictal periods were observed.Results:One hundred and thirty-two seizures were recorded in these 16 patients. Two patterns at initial period were noted: low-voltage fast activity (LVFA)+slow depolarizing shifts (SPSs, n=29, 22%), and rhythmic activity (RA) of low-medium amplitude without SPSs ( n=103, 78%); spatial spread of LVFA+SPSs was much wilder than that of RA. In addition, 3 patterns at preictal period were summarized: hypersynchronous (HYP, n=93, 70.5%, most commonly found in the anterior hippocampus [87/219]), sentinel spike ( n=22, 16.7%), and pattern of smooth transition from the interictal period to the initial period ( n=17, 12.9%). No special correspondence in discharge patterns was noted between the initial period and preictal period. Conclusion:Seizure is a process of gradual evolution from interictal period, preictal period to initial period. HYP potential is the most common pattern of seizure in MTLE at preictal stage, mainly appeared in the anterior hippocampus; RA potential is the most common pattern of seizure in MTLE at initial stage, with lower frequency and more limited spatial spread.
