Objective To explore a method for rapid and differential diagnosis of rejection after kidney transplantation through urine hyperspectral imaging technology. Methods Hyperspectral data information from urine samples of 118 recipients after kidney transplantation was collected, and a deep learning model was constructed to diagnose and classify the types of rejection. Results A deep learning diagnostic model based on the 34-layer residual network (ResNet-34) was constructed, and 118 patients were included and divided into the training set and the test set. Based on the pathological results of the transplanted kidney puncture, the urine samples of the patients were classified into five groups: the non-rejection group, the T-cell-mediated rejection group, the antibody-mediated rejection group, the mixed rejection group and the nephropathy recurrence group. The results showed that the diagnostic sensitivities of the model for the above five groups were 0.960, 0.980, 0.930, 0.940 and 0.943 respectively, and the diagnostic specificities were 0.983, 0.993, 0.997, 0.989 and 0.989 respectively. The overall diagnostic accuracy rate reached 95.7%. Conclusions The study provides a non-invasive, rapid and accurate auxiliary diagnostic method for the differential diagnosis of rejection after kidney transplantation.

ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

OBJECTIVE To explore the effect and mechanism of warming channels and activating blood circulation external treat-ment to alleviate peripheral hyperalgesia in knee osteoarthritis(KOA)based on NGF/TrKA signaling pathway.METHODS 30 SD rats were randomly divided into normal group,KOA group and Yiceng group.KOA model was established by anterior cruciate ligament transection(ACLT).14 days after model establishment,rats in Yiceng group were treated with Yiceng patch.The peripheral pain threshold of rats was measured at different time points.The cartilage sections were stained with HE,Aggrecan and type II collagen.The synovial sections were stained with HE,Sirius red,silver and performed with immunostaining.The protein expression of key molecules NGF and TrKA of NGF/TrKA signaling pathway,inflammatory index IL-1β,pain mediator TRPV1,pan-neural mark-ers PGP9.5 and S100 in synovium and complexes transported to dorsal root ganglia(DRG)tissues via nerve endings was determined by Western Blot.The corresponding gene expression was determined by qPCR.The levels of NGF and SP in peripheral blood of rats were determined by ELISA.RESULTS Compared with the KOA group,the cold allodynia and mechanical allodynia thresholds of the rats in the Yiceng group increased(P<0.05,P<0.01);the protein and gene expression of NGF,TrKA,TRPV1,IL-1β,PGP9.5 in the synovial tissue decreased(P<0.05,P<0.01);the protein and gene expression levels of TRPV1,PGP9.5,S100 in the DRG tissue were downregulated(P<0.05,P<0.01).CONCLUSION The warming channels and activating blood circulation external treatment can inhibit the NGF/TrKA signaling pathway,downregulate the gene and protein expressions of NGF,TrKA,TRPV1,IL-1β,PGP9.5,and may inhibit the sprouting of sensory nerve fibers and improve the peripheral hyperalgesia state of rats with KOA.

As a malignant hematological disease mainly originating from T or B lymphoid progenitor cell, acute lymphocytic leukemia (ALL) is more prevalent in children. With the gradual revelation of the autophagy mechanism, the role of autophagy in ALL has gained increasing attention. Autophagy can not only stimulate the survival of leukemia cells as an adaptive response, but also inhibit cell proliferation in some other cases. Therefore, how to regulate autophagy in promoting death or survival and reduce the drug resistance in ALL has become a hotspot. This article reviews the role of autophagy in ALL.

ObjectiveTo observe the effects of Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the Haizao Yuhutang （HYT） on oxidative stress in the liver of goiter rats under the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020. MethodA total of 128 male Wistar rats were randomly divided into a blank group， a model group， a euthyrox group （20 μg·kg^-1）， a HYT group （12.06 g·kg^-1）， a HYT without Sargassum （HYT-H） group （9.90 g·kg^-1）， a HYT without Glycyrrhizae Radix et Rhizoma （HYT-G） group （10.26 g·kg^-1）， a HYT without Sargassum and Glycyrrhizae Radix et Rhizoma （HYT-HG） group （8.10 g·kg^-1）， and a Sargassum and Glycyrrhizae Radix et Rhizoma （HG） group （3.96 g·kg^-1）. The blank group was given deionized water by gavage， and the others were given propylthiouracil （PTU） to replicate the goiter pathological model. Euthyrox was taken as a positive control drug， and the rest of the Chinese medicine groups were given the corresponding decoction by gavage， the material was collected 12 hours after the last dose. The serum levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， alkaline phosphatase （ALP）， and the contents of superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px）， malondialdehyde （MDA）， reactive oxygen species （ROS） in liver tissue were detected in each group. The pathological changes in the liver were observed via hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was utilized to detect the mRNA expressions of Kelch-like Ech-associated protein 1 （Keap1）， nuclear factor E₂-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， p53 and Caspase-3 in liver tissues. Western blot was adopted to detect the protein expressions of Nrf2 and HO-1 in liver tissues in oxidative stress-related signaling pathways. ResultCompared with control group， the model group showed significantly increased serum ALT level and contents of MDA and ROS in liver tissues （P<0.05， P<0.01）， significantly reduced activities of SOD and GSH-Px in the liver （P<0.01）， significantly increased mRNA expression of Keap1 （P<0.01）， and significantly decreased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. Compared with the model group， the HYT group manifested significantly reduced serum levels of AST， ALT， and ALP （P<0.05， P<0.01）， significantly reduced contents of MDA and ROS in liver tissue （P<0.01）， significantly increased the activities of SOD and GSH-Px （P<0.01）， significantly decreased mRNA expressions of Keap1， p53， and Caspase-3 （P<0.01）， and significantly increased mRNA and protein expressions of Nrf2 and HO-1 （P<0.05， P<0.01）. ConclusionUnder the condition of 2 times the dose limit of the Pharmacopoeia of the People's Republic of China 2020， Sargassum and Glycyrrhizae Radix et Rhizoma incompatible pair with the HYT on oxidative stress in the liver of goiter rats had different effects. The HYT that contains Sargassum and Glycyrrhizae Radix et Rhizoma has a protective effect on the liver of goiter rats， and the effect is better than that of the HG group， the euthyrox group， and the incomplete groups. Its mechanism may be related to activating the Nrf2/HO-1 signaling pathway to alleviate liver oxidative stress and inhibiting the p53/Caspase-3 signaling pathway to reduce hepatocyte apoptosis.

Objective:To investigate the effect of insular involvement on the outcomes of patients with acute anterior circulation ischemic stroke.Methods:Patients with acute anterior circulation ischemic stroke admitted to the Department of Neurology, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University from January 2015 to December 2020 were retrospectively included. Demographic data, vascular risk factors, clinical and laboratory data, as well as treatment and outcomes were collected. Firstly, the correlation between the insular involvement and the outcomes was investigated, and then the bootstrap method was used to clarify the mediating role of infarct volume between the insular involvement and the poor outcomes.Results:A total of 450 patients with acute anterior circulation ischemic stroke were enrolled, among whom 79 cases (17.6%) had insular involvement and 41 (9.1%) had left insular involvement. There were 111 (24.7%) with poor outcomes, including 5 (1.1%) died. Compared to the non-insular involvement group, the insular involvement group had a higher proportion of patients with atrial fibrillation, shorter onset to door time, higher neutrophil-to-lymphocyte ratio (NLR), higher National Institutes of Health Stroke Scale (NIHSS) score at admission, larger infarct volume, and higher proportion of patients with poor outcomes (all P<0.05). In addition, patients with left insular involvement were younger than those with right insular involvement, had a higher baseline NIHSS score, a lower proportion of patients with minor stroke (NIHSS score ≤8), and had a longer onset to door time (all P<0.05). Compared to the good outcome group, the poor outcome group was older, with a higher proportion of female patients, higher systolic blood pressure, blood glucose, NLR, and NIHSS scores at admission, larger infarct volume, and a higher proportion of patients with insular involvement (all P<0.05). Mediation analysis suggested that the mediating effect of infarct volume between the insular involvement and the poor outcomes was significant (95% confidence interval 0.033-0.230; P=0.008). Conclusions:insular involvement in patients with acute anterior circulation ischemic stroke is associated with the poor outcomes, and this association may be mediated by infarct volume. Patients with left insular involvement may have more severe symptoms than those with right insular involvement, but there is no significant difference in the outcomes.

Objective     To investigate the risk factors for postoperative complications Clavien-Dindo classification≥grade Ⅱ after lung cancer surgery. Methods     The patients who underwent lung cancer surgery in a multicenter observational study from November 2017 to January 2020 were included. The Clavien-Dindo classification of postoperative complications was analyzed. Logistic regression was used to identify the risk factors for complications≥ gradeⅡ. Results     A total of 388 patients were enrolled, including 203 males and 185 females with a mean age of 56.14±10.36 years. The incidence of postoperative complications was 25.52% (99/388) after lung cancer surgery and the incidence of complications≥gradeⅡ was 20.10% (78/388). The five most common postoperative complications were pneumonia (6.96%), prolonged pulmonary air leak (>7 days, 5.67%), incision dehiscence (4.64%), arrhythmia (3.87%), and postoperative pleural effusion (3.35%). Multivariate analysis showed that open surgery [reference: uniportal thoracoscopic surgery, OR=2.18, 95%CI (1.01, 4.70), P=0.047], extended resection [reference: sublobar resection, OR=2.86, 95%CI (1.11, 7.19), P=0.030; reference: lobectomy, OR=2.20, 95%CI (1.10, 4.40), P=0.026] and operative time≥3 h [OR=2.07, 95%CI (1.12, 3.85), P=0.021] were independent risk factors for postoperative complications≥gradeⅡ after lung cancer surgery. Conclusion     Surgical approach, extent of resection and operative time are independent influencing factors for postoperative complications≥gradeⅡ after lung cancer surgery.

Objective To explore the effectiveness of the Five Elements Music Therapy(FEMT)in relieving stress in participants with different cultural backgrounds,and to compare the differences between the FEMT and the Western Art Music Therapy(WAMT)in stress relief.Methods This was a comparative pilot randomized pre-post repeated measures study,37 subjects were allocated with 2 dropped out,with an inclusion-ended sample of 35 subjects,23 from Canada and 12 from China.After informed consent,all subjects were randomly assigned to listening to either Five Elements Music or Western Art Music at home for 30 minutes,twice a week for four weeks.Participants were asked to use headphones,measure their pulse rate before and after each session,and fill out five questionnaires,including a background and demographic survey(reporting age,gender,education,cultural background,listening experience).Self-assessment of stress(pre-post after each session),General Hospital Anxiety/Depression Scale(HADS,weekly after 2nd session),Perceived Stress Survey(PSS,weekly after 2nd session),the Music Therapy Intervention Survey(MTIS,pre-post each session).Results ①There was a significant decrease in self-assessed stress scores after the second session in the FEMT compared with the WAMT group(t=-2.057,P=0.046).②In both groups,there was a significant decrease in stress scores pre-post treatment in each group(WAMT t=5.026;FEMT T=7.645,P=0.000).③There was no significant difference between the two groups in post-intervention HADS scores(P>0.05);In the Chinese sample,there was a significant difference in HADS scores after the eighth session in both FEMT and WAMT groups(t=-3.862,P=0.003),and a statistically significant difference in HADS pre-post intervention in the FEMT((t=5.117,P=0.004).There was a significant difference in MTIS pre-post treatment in the WAMT(t=-2.572,P=0.023),but in not the FEMT group(t= 1.331,P=0.207).Conclusion This pilot trial explores a safe and feasible self-administered music therapy approach for stress in two distinct cultural groups,and for the first time provides preliminary comparison and evidence of effectiveness of FEMT and WAMT in alleviating stress and anxiety.Further investigation with bigger randomized samples is needed to elucidate the effects of different kinds of music and cultural groups on stress and anxiety levels.

Objective:To investigate the value of net water uptake (NWU) for predicting early neurological improvement (ENI) after endovascular treatment in patients with acute anterior circulation large vessel occlusion stroke.Methods:A case-control study. A total of 132 patients (80 men, 52 women, median age 68 years) with acute anterior circulation large vessel occlusive stroke receiving endovascular treatment were retrospectively analyzed at Jinling Hospital from October 2014 to September 2019. Patients were divided into two groups based on the occurrence of ENI, which was defined as either an improvement of NIHSS score of ≥4 points, or an NIHSS score of 0 or 1 at 24 hours after endovascular treatment. The rank sum test, Chi square test, and other methods were used to compare differences in baseline characteristics between the two groups. Logistic regression analysis was used to investigate independent predictors of postoperative ENI. Receiver operating characteristic curve analysis used to assess the capacity of NWU to predict ENI.Results:Of the 132 patients in the study, ENI occurred in 47 and did not occur in 85. In multivariate logistic regression analysis age [odds ratio ( OR)=0.940, 95% confidence interval ( CI) 0.903-0.979, P=0.003], time from stroke onset to puncture ( OR=0.995, 95% CI 0.991-0.999, P=0.025), time from puncture to recanalization/end of operation ( OR=0.985, 95% CI 0.974-0.996, P=0.007), NWU ( OR=0.762, 95% CI 0.620-0.937, P=0.010), and mTICI ( OR=1.644, 95% CI 1.043-2.590, P=0.032) were predictive factors for ENI. Receiver operating characteristic curve analysis indicated that NWU could effectively predict ENI (area under the curve=0.642, 95% CI 0.543-0.741, P=0.007), and prediction accuracy was improved when it was combined with other clinical parameters. Conclusion:NWU is an independent predictor of ENI in patients with acute anterior circulation large vessel occlusive stroke undergoing endovascular treatment.
