As an innovative form of combining traditional aromatherapy with modern nasal medicine delivery technology， "olfactory administration of Chinese medicine" carries the theoretical essence of traditional Chinese medicine （TCM）， which is "moving and channeling Qi and fragrance， dredging and awakening the mind". Based on the systematic records of olfactory therapies in ancient books in emergency care， disorders of consciousness， lung system， and gynecological diseases， this paper examines the historical evolution of its clinical application， and elucidates the profound historical basis and theoretical feasibility of "olfactory administration of Chinese medicine" as a new form. Combined with the innovation and precise application of modern Chinese medicine olfactory agents in multi-system diseases such as nervous， respiratory， and cardiovascular diseases， this paper further analyzes the multi-dimensional mechanism of olfactory receptor pathway， olfactory brain pathway， nasal mucosal blood vessels， and lymphatic channels， and demonstrates its advantages of rapid onset， targeted brain entry， and systemic regulation. Under the background of continuous growth in the demand for external TCM treatment， continuous breakthroughs in the technology of nasal dosage forms， and increasingly accurate drug delivery paths， Chinese medicine olfactory agents have shown significant practical applicability and development potential. This study aims to provide theoretical support and practical direction for the system construction of this form.

Antibody-drug conjugates (ADCs) are antitumor drugs composed of monoclonal antibodies and cytotoxic payload covalently coupled by a linker. Currently, 15 ADCs have been clinically approved worldwide. More than 100 clinical trials at different phases are underway to investigate the newly developed ADCs. ADCs represent one of the fastest growing classes of targeted antitumor drugs in oncology drug development. It takes advantage of the specific targeting of tumor-specific antigen by antibodies to deliver cytotoxic chemotherapeutic drugs precisely to tumor cells, thereby producing promising antitumor efficacy and favorable adverse effect profiles. However, emergence of drug resistance has severely hindered the clinical efficacy of ADCs. In this review, we introduce the structure and mechanism of ADCs, describe the development of ADCs, summarized the latest research about the mechanisms of ADC resistance, discussed the strategies to overcome ADCs resistance, and predicted biomarkers for treatment response to ADC, aiming to contribute to the development of ADCs in the future.

Objective To systematically evaluate the risk prediction models for neonatal early-onset sepsis(EOS),aiming to provide reference for the construction and optimization of models,as well as for clinical selection of appro-priate prediction models.Methods PubMed,Web of Science,Embase,Cochrane Library,China National Know-ledge Infrastructure(CNKI),Wanfang Data,China Biology Medicine disc(CBM),and VIP databases were re-trieved,and studies relevant to neonatal EOS risk prediction models were collected.The retrieval period was from the inception of the database to January 18,2025.Two researchers independently screened literatures,extracted da-ta,and evaluated the quality of the included literatures using PROBAST tool.Any disagreements were resolved through consultation with a third reviewer.Results A total of 14 literatures were included in analysis,containing 19 risk prediction models.The area under receiver operating characteristic(ROC)curve(AUC)of the included model ranged 0.71-0.999.The number of prediction factors ranged 3-21.Common prediction factors included young gestational age,low birth weight,1-minute Apgar score,abnormal neonatal temperature,prolonged prema-ture rupture of membranes,amniotic fluid turbidity,maternal Group B streptococcal infection,maternal chorioam-nionitis,as well as elevated levels of procalcitonin and C-reactive protein in neonates.The risk of model overall bias was high,mainly due to insufficient number of outcome variable events in the analysis field,improper processing of missing data,screening of prediction factors based on univariate analysis,lacking model performance evaluation,and overfitting of model.Conclusion The neonatal EOS risk prediction model is still at the development stage.Al-though the current prediction models have better overall predictive performance,the overall quality needs to be im-proved.Future modeling can follow the PROBAST and TRIPOD specifications to reduce bias risk,explore the com-bination of multiple modeling methods,and focus on strengthening external validation and localized application to enhance the clinical applicability and promotion value of the model.

Objective To explore the regulatory effect of long non-coding RNA HOX transcript anti-sense RNA(lnRNA HOTAIR)targeting tuberous sclerosis complex 1(TSC1)on podocyte injury in diabetic nephropathy(DN).Methods Mice podocyte MPC5 were divided into 6 groups:the control group,the high glucose group(the HG group),the HG+si-NC group,the HG+si-HOTAIR group,the HG+si-HOTAIR+sh-NC group,and the HG+si-HOTAIR+sh-TSC1 group.qPCR was used to detect the levels of lnRNA HO-TAIR and TSC1 mRNA.Cell viability was detected by cell counting kit-8(CCK-8),and apoptosis was detec-ted by flow cytometry.ELISA was used to detect the levels of inflammatory factors[IL-6,tumor necrosis fac-tor-α(TNF-α)]and the levels of oxidative stress indicators[reactive oxygen species(ROS),malondialdehyde(MDA),superoxide dismutase(SOD)]were detected by corresponding reagent kit.Results Compared with the control group,the levels of lnRNA HOTAIR,apoptosis rate,IL-6,TNF-α,ROS and MDA in the HG group were significantly increased(P<0.05),while the levels of TSC1 mRNA,cell viability and SOD were significantly decreased(P<0.05).Compared with the HG+si-NC group,the levels of lnRNA HOTAIR,ap-optosis rate,IL-6,TNF-α,ROS and MDA in the HG+si-HOTAIR group significantly decreased(P<0.05),the levels of TSC1 mRNA,cell viability and SOD were significant increased(P<0.05).Compared with the HG+si-HOTAIR+sh-NC group,the levels of apoptosis rate,IL-6,TNF-α,ROS and MDA in the HG+si-HOTAIR+sh-TSC1 group were significantly increased(P<0.05),the levels of TSC1 mRNA,cell viability and SOD were significantly decreased(P<0.05).Conclusion Silencing lnRNA HOTAIR can target TSC1 to regulate the activity,apoptosis rate,inflammatory level and oxidative stress levels of podocyte injury in DN,thereby alleviating podocyte damage in DN.

Objective To explore the correlation between HbA1c level and carotid plaque stability in type 2 diabetes mellitus(T2DM)patients.Methods From October 2018 to October 2020,100 T2DM patients who visited our hospital and underwent carotid artery ultrasound examination with a plaque thickness greater than 1.5 mm were included in this study.According to HbA1c levels,they were divided into HbA1c≤7%group(n=21),7%9%group(n=51).Results The FPGs of the 7%9%groups were higher than that of the HbA1c≤7%group(P<0.01).The plaque thickness gradually increased from group HbA1c≤7%,7%9%groups(P<0.01),and the proportion of high-level enhancement in the overall,proximal,middle,and distal segments of the plaque increased in sequence(P<0.05 or P<0.01).Pearson correlation analysis showed that HbA1c,FPG,and 2 hPG were positively correlated with plaque thickness and length(P<0.05).Spearman correlation analysis showed that HbA1c was positively correlated with the smoothness of the plaque surface,the presence of extremely low echogenicity within the plaque,and the overall,proximal,central,and distal enhancement intensity of the plaque(P<0.05).Conclusion HbA1c can not only evaluate the blood glucose control of T2DM patients,but also has a certain correlation with the stability of carotid plaque,with a trend of poorer plaque stability as HbA1c increases.

Amyloidosis is a metabolic disease characterized by the deposition of amyloidogenic fibrils in multiple organs, which causes structural disorders, leading to a decline in organ function and in the case of myocardial involvement, damage to the structure and function of the heart, which is the main cause of mortality. However, the disease is often misdiagnosed or underdiagnosed due to its insidious onset and lack of specificity in clinical manifestations. 99Tc m-pyrophosphate (PYP) SPECT is a noninvasive test that can not only identify cardiac amyloid deposits at an early stage but also provide a useful tool for the diagnosis of cardiac amyloidosis. This article briefly describes the traditional screening methods for cardiac amyloidosis, outlines their limitations, and focuses on the clinical diagnostic value of 99Tc m-PYP SPECT in cardiac amyloidosis.

Objective:To investigate the impact of rosacea on patients＇ quality of life and mental health, and to analyze variations across different subtypes, gender, sun exposure, smoking status, ethnicity, and educational levels, as well as patients＇ demands for treatment.Methods:It was a cross-sectional study from October 2022 to January 2024, 177 rosacea patients from the Department of Dermatology, the First Affiliated Hospital of Kunming Medical University were surveyed. The cohort comprised 36 males and 141 females, with a median age of 35 (29, 44) years. Data collected through questionnaires included general information, Dermatology Life Quality Index (DLQI), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Patient Need Questionnaire (PNQ). Statistical analysis was conducted on the collected data.Results:The median DLQI score was 10 (3, 15), indicating moderate impact. The median GAD-7 score was 5 (2, 7), suggesting mild anxiety; while the median PHQ-9 score was 6 (2, 9), indicating mild depression. Female patients scored higher in both DLQI and GAD-7 than males ( P<0.05). Papulopustular subtypes had higher DLQI and GAD-7 scores compared to other subtypes ( P<0.01). Patients with lower education levels scored higher in DLQI and GAD-7 than those with higher education ( P<0.01), and non-smokers had higher GAD-7 scores than smokers ( P<0.05). Significant positive correlations were found between DLQI and PHQ-9 ( r=0.39, P<0.01), and DLQI and GAD-7 ( r=0.51, P<0.01), as well as between PHQ-9 and GAD-7 ( r=0.59, P<0.01). Regarding treatment needs, 159 patients (89.8%) expressed a strong desire for a clear diagnosis and treatment plan, and the same number wished for a complete resolution of all skin lesions. Female patients consistently demonstrated significantly stronger demands in all 28 treatment need items (all P<0.05). Conclusions:Rosacea significantly affects patients＇ quality of life and mental health, particularly among females, individuals with papulopustular subtypes, and those with lower education levels. There is a strong demand for definitive diagnostic and therapeutic plans, especially among female patients.

ObjectiveTo compare the effects of topical application of Modified Sanhuang Powder （加味三黄散， MSP） combined with cold compression versus cold compression alone on swelling and pain after knee arthroscopy through a retrospective cohort study. MethodsMedical records of 134 patients with knee arthroscopy-induced knee swelling and pain were divided into non-exposure group （51 cases） and exposure group （83 cases） based on whether they used MSP for external application after surgery. The non-exposure group received simple cold compression therapy in addition to functional exercise and routine treatment after surgery， while the exposure group received topical MSP on the basis of what were given in the non-exposure group. The Visual Analog Scale （VAS） scores were compared between the two groups before and 7 days after treatment， and knee swelling measurements were taken before and 3， 5， and 7 days after treatment. The clinical effective rate was compared between the two groups. ResultsThe VAS scores in both groups were lower after treatment （P＜0.05）， and the exposure group had lower scores than the non-exposure group （P＜0.05）. On the 3rd， 5th， and 7th days of treatment， the scores on swelling at 2 cm above the superior pole of the patella， at the midline of the patella， and 5 cm below the inferior pole of the patella significantly decreased after treatment in both groups （P＜0.05）， and the exposure group had lower scores than the non-exposure group （P＜0.05）. The total clinical effective rate in the exposure group was 91.56% （76/83）， which was higher than 78.43% （40/51） in the non-exposure group （P＜0.05）. ConclusionTopical application of MSP combined with cold compression is effective in relieving postoperative swelling and pain after knee arthroscopy and is superior to cold compress alone.

Objective:To evaluate the effects of vaccine switch on the levels of neutralizing antibody (NA) of poliovirus in children aged<12 years.Methods:Subjects aged<12 years from 9 districts in Fujian province were chosen by stratified cluster and complete random sampling method. Blood samples were collected for testing NA of poliovirus by microcell neutralization.Results:A total of 2 134 subjects aged<12 years were selected. The positive rate of NA against PVⅠand Ⅲ were 98.64% and 95.83%; and geometric mean titers (GMTs) were 1∶259.35 and 1∶105.14, respectively. The GMTs presented a trend of decreasing as age increased. Compared to trivalent oral poliovirus vaccine (tOPV), bivalent oral poliovirus vaccine (bOPV) and inactivated poliovirus vaccine (IPV) induced higher GMTs of NA against poliovirusⅠand Ⅲ respectively. Among 182 children aged<5 years, the positive rate of NA against PVⅠ, Ⅱ, Ⅲ were 97.25%, 76.37% and 92.86%. There were statistical differences among the three types ( χ2=44.44, P=0.000). The rate of NA against PVⅡwas significantly lower than those ofⅠand Ⅲ (Ⅱ vs. I: χ2=34.65, P=0.000; Ⅱ vs. Ⅲ: χ2=18.99, P=0.000). And the GMTs of NA against PV Ⅰ, Ⅱ, Ⅲ were 1∶368.96、1∶23.06 and 1∶183.10, which were significantly different ( F=156.54, P=0.000). The GMT of PVⅠwas the highest, PV Ⅲ was the second, PVⅡ was lowest (pairwise comparison showed values of P all were 0.000). The analysis of general linear model showed that the interval between the date of last immunization and the date of sample collection would affect the GMTs of PVⅠand Ⅲ, different vaccine models would affect only the GMT of PV Ⅰ. The age maybe was a confounding factor. But no factors would affect the GMT of PV Ⅱ. Conclusions:After the vaccine switch, the level of NA against PVⅠand PV Ⅲ were still maintaining high level, but the level of PVⅡamong children<5 years was at relatively low level, which indicated that the surveillance should be strengthened.
