The Mofeng Ointment Formulation （MOF， 摩风膏方） is recorded in the Dunhuang manuscript Unnamed Treatise on the Pulse （《亡名氏脉经》） and stands as a representative ancient external therapeutic formula in traditional Chinese medicine （TCM）. Known for dispelling wind， activating blood circulation， warming the meridians， and relieving pain， it is particularly effective in treating rheumatic arthralgia. Through literature research， this paper systematically reviews the composition， preparation techniques， and clinical application characteristics of MOF. In recent years， advancements in modern pharmaceutical technology have led to the development of various innovative ointment-based formulations derived from the traditional recipe， such as Dunhuang Xiaoding Ointment （敦煌消定膏）， Dunhuang Xiaozhong and Zhentong Ointment （Patch） （敦煌消肿镇痛膏/贴）， Xiaoding Ointment （消定膏） gel patch， and Xiaoding Ointment （消定膏） cataplasm. These innovations explore pathways for transforming classical prescriptions into modern applications， providing a theoretical basis for the external TCM treatment of pain-related and orthopedic conditions.

Objective To analyze the nonlinear relationship between hypothermic machine perfusion (HMP) parameters and delayed graft function (DGF) and optimize the construction of a predictive model for DGF. Methods The data of 923 recipients who underwent kidney transplantation from deceased donors were retrospectively analyzed. According to the occurrence of DGF, the recipients were divided into DGF group (n=823) and non-DGF group (n=100). Donor data, HMP parameters and recipient data were analyzed for both groups. The nonlinear relationship between HMP parameters and the occurrence of DGF was explored based on restricted cubic splines (RCS). Over-sampling, under-sampling and balanced sampling were used to address the imbalance in the proportion of DGF to construct logistic regression predictive models. The area under the curve (AUC) of each model was compared in the validation set, and a nomogram model was constructed. Results Donor BMI, cold ischemia time of the donor kidney, and HMP parameters (initial and final pressures, resistance, and perfusion time) were significantly different between the DGF and non-DGF groups (all P<0.05). The RCS analysis revealed a threshold-like nonlinear relationship between HMP parameters and the risk of DGF. Among the models constructed using different sampling methods, the balanced sampling model had the highest AUC. Using this model, a nomogram was constructed to stratify recipients based on risk scores. Recipients in the high-risk group had higher serum creatinine levels at 1, 6, and 12 months after kidney transplantation compared to those in the low-risk group (all P<0.05). Conclusions There is a nonlinear relationship between HMP parameters and the risk of DGF, and the threshold is helpful for organ quality assessment and monitoring of graft function after transplantation. The predictive model for DGF constructed on the base of balanced sampling algorithms helps perioperative decision-making and postoperative graft function monitoring of kidney transplantation.

Objective:To investigate whether endoplasmic reticulum transmembrane protein IRE1(encoded by Ern1)can modulate the immunogenicity and tumorigenicity of cancer cells and explore the underlying mechanism.Methods:Correlation between ERN1 expression and the overall survival of cancer patients was explored with public cancer databases.CRISPR-Cas9 technology was used to delete Ern1 in mouse tumor cell lines MCA205 and TC-1.By CCK-8,flow cytometry,ELISA,luciferase reporter systems,subcutaneous tumor models,prime-boost regimens,we analyzed impact of Ern1 on tumor cell proliferation in vitro and tumor growth in vivo,intratumoral immune cell composition,tunicamycin-induced immunogenic cell death and activation of anti-tumor effector T cells.The growth kinetics of Ern1-/-tumors was also monitored in Ifnar-/-mice.Results:ERN1 expression was found to be negatively correlated with the overall survival of cancer patients across multiple cancer types.Although Ern1 deficiency didn't affect tumor cell proliferation in vitro,it largely delayed tumor growth or caused spontaneous tumor regression in immune-competent mice.As compared to wild type counterparts,Ern1-/-tumors harbored much more neutrophils but significantly less CD4+T cells.Upon tunicamycin-induced endoplasmic reticulum stress,Ern1-/-cells were more vulnerable to cell death.Although Ern1-deficiency reduced HMGB1 release and calreticulin exposure,IFN-α/β secretion was increased,and strongly elevated type Ⅰ IFN response in tumor cells and augmented IFN-γ production by anti-tumor effector T cells.Ern1-/-tumor cells restored the tumorigenic capacity in Ifnar-/-mice.Conclusion:Ern1 defi-ciency can enhance the immunogenicity of tumor cells and inhibit tumor outgrowth by boosting endoplasmic reticulum stress-induced type Ⅰ IFN response.

Objective To explore the applicability and optimal cut-off of the revised Cubbin & Jackson scale in the diagnosis of pressure injury in ICU patients in China.Methods From April 2021 to October 2022,6 203 ICU patients from 35 tertiary hospitals in Gansu Province were included in the study by convenience sampling method.The standardized trained ICU nurses examined the skin and collected relevant data,determined whether or not there was pressure injury and its stage,and simultaneously used the revised Cubbin & Jackson scale for pressure injury risk assessment.The software was used to statistically analyze the area under the receive operating characteristic curve(AUC),Yoden index,sensitivity,specificity and other indexes of the revised Cubbin & Jackson scale in the diagnosis of pressure injury in ICU patients.Results A total of 79 cases of pressure injury occurred during hospitalization in 6 203 ICU patients,with an incidence of 1.27％.Hierarchical analysis showed that the AUC of the revised Cubbin & Jackson scale in the prediction and diagnosis of pressure injury ranged from 0.74 to 0.92 in ICU patients with different sex,age,length of ICU stay,whether or not mechanically ventilated,and whether or not surgical.The Yoden index,sensitivity and specificity were 0.40-0.74,77.27％-94.44％and 62.44％-82.63％,respectively.When the total score was ≤28 points,the revised Cubbin & Jackson scale obtained the highest AUC(0.86),and the Yoden index,sensitivity,specificity,positive predictive value,negative predictive value,positive likelihood ratio,and negative likelihood ratio were 0.60,92.41％,67.26％,3.50％,99.86％,2.82 and 0.11,respectively.Conclusion The revised Cubbin & Jackson scale can be used as a suitable tool to effectively predict and diagnose pressure injury in ICU patients in China,and the optimal cut-off of ≤28 points is appropriate.

Objective:To compare the clinical value of digital breast tomosynthesis (DBT) localization and stereotactic positioning biopsy of breast lesions.Methods:This study was a cross-sectional study. Totally of 250 patients who underwent breast biopsy at Shenzhen People′s Hospital, Luohu District People′s Hospital and Peking University Shenzhen Hospital between August 2021 to October 2023 was analyzed retrospectively, including 136 cases of DBT-guided biopsy (DBT-guided group) and 114 cases of stereotactic-guided biopsy (stereotactic-guided group). The stereotactic-guided biopsy methods included core needle biopsy (CNB) and wire positioning. The DBT-guided biopsy methods included CNB, wire positioning and vacuum-assisted breast biopsy (VABB). The χ2 test or Mann-Whitney U test was used to compare the puncture success rate, operation time, localization time, puncture time, number of first valid localization phases obtained, number of exposures, and complications of different biopsy methods between 2 groups. Results:In the wire positioning biopy, the puncture success rate was 100% (33/33) in DBT-guided group and 96% (48/50) in the stereotactic-guided group, with no statistically significant difference between the two groups ( P=0.515). Compared to the stereotactic-guided group, the operation time and localization time were shorter, and the number of first valid localization phases obtained, number of exposures were fewer in the DBT-guided group( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.871). In CNB, both the DBT-guided group and the stereotactic-guided group had higher puncture success rates, with no statistically significant difference ( P=0.080). Compared to the stereotactic-guided group, the operation time, localization time and puncture time were shorter, and the number of first valid localization phases obtained, number of exposures were lower in the DBT-guided group, and the difference between the two groups were statistically significant ( P<0.05). The incidence of complications was lower in both the DBT-guided group and the stereotactic-guided group, with no statistically significant difference ( P=0.627). Twenty-one cases received DBT-guided VABB, with an operation time of (19.90±3.38) min, a localization time of 6.00 (6.00, 7.00) min, a puncture time of (13.42±3.28) min, the number of first effective localization phases obtained was 1.00 (1.00, 1.00) time, the number of exposures was 4.00 (3.50, 5.00) times, and one case experienced severe pain after puncture. Conclusion:Compared with stereotactic-guided biopsy, DBT-guided biopsy can reduce operation time and exposure times, and can target more types of breast lesions, with higher clinical application value.

In recent years， the research data on the combination model of insomnia of liver depression and qi stagnation syndrome in traditional Chinese medicine （TCM） were sorted out and summarized in terms of the selection of experimental animals， modelling methods， and model evaluation， with a view to providing references for the standardized preparation of the experimental model of insomnia of liver depression and qi stagnation syndrome and the study of the intervention mechanism. As for the selection of experimental animals， rats and mice are commonly used for the study of sleep patterns in the insomnia model of liver depression and qi stagnation syndrome because their sleep patterns are similar to those of human beings； zebrafish is suitable for the study of sleep patterns in early development because of its high genetic homology； and rhesus macaques， common marmosets， and crab-eating monkeys are used for the study of highly complex sleep disorders because their physiological and behavioural characteristics are closer to those of human beings. In terms of modelling methods， electrical stimulation， chronic restraint， chronic emotional stress and impact psychological stress each have their own characteristics and application scenarios， while chronic tail-clamping stimulation combined with intraperitoneal injection of p-chlorophenylalanine （PCPA） combines physical and chemical stimuli， in order to simulate the complex mechanism of insomnia in human beings， and to more comprehensively simulate the pathology of insomnia with liver depression and qi stagnation syndrome. In terms of evaluation indexes， electroencephalography （EEG） and electromyography （EMG） monitoring and barbiturate synergistic sleep test are the most commonly used and scientific methods for evaluating insomnia animal models with liver depression and qi stagnation syndrome， which can provide intuitive and continuous sleep state monitoring； barbiturate synergistic sleep test can reflect the sensitivity and responsiveness of the model animals to the sleep-regulating medications； and the introduction of the method of using formulas to measure syndromes for the evaluating the model can combine the treatment and diagnostic principles of TCM with modern scientific research.
