ObjectiveTo explore the clinical efficacy of Juanbitang hot compress pack combined with intensive rehabilitation training in stroke patients with hemiplegia. MethodsA total of 80 stroke patients with hemiplegia were selected and assigned into a control group （40 cases） and an observation group （40 cases） according to the random number table method. The control group received conventional rehabilitation training and nursing intervention，while the observation group was additionally treated with Juanbitang hot compress pack. The two groups were compared in terms of the neurological function （national institute of health stroke scale score，NIHSS score），muscle strength，motor function （fugl-meyer assessment scale score，FMA score），daily living activity （modified barthel index，MBI），balance ability （berg balance scale score，BBS score），trunk control ability （Sheikh Trunk Control Test score，Sheikh TCT score），and homocysteine （Hcy） level before and after treatment. ResultsAfter treatment，the observation group had lower NIHSS score and Hcy level than the control group （P<0.05）. The total response rate of the observation group （97.50%） was higher than that of the control group （77.50%）. The scores of upper limb and lower limb FMA，MBI，BBS，and Sheikh TCT in the observation group were all higher than those in the control group （P<0.05）. ConclusionThe application of Juanbitang hot compress pack combined with rehabilitation training can effectively improve the neurological function，muscle strength，motor function，daily living ability，balance ability，and trunk control ability and reduce the Hcy level in stroke patients with hemiplegia，demonstrating enhanced clinical efficacy.

[Objective] To compare the efficacy and safety of deglycerolized red blood cells (DRBC) and suspended red blood cells (SRBC) based on the propensity score matching (PSM) method, so as to provide evidence for the rational use of DRBC resources in clinical practice. [Methods] A total of 89 patients who received DRBC transfusion and 2 916 patients who received SRBC transfusion in our hospital from January 2023 to September 2024 were included. A 1∶1 nearest neighbor PSM was used to balance covariates such as gender, age, and body mass index (BMI). The changes of hemoglobin (Hb), red blood cell (RBC) count, hematocrit (HCT), and inflammatory markers such as white blood cell (WBC) count, neutrophil (NE) count, C-reactive protein (CRP), and Interleukin-6(IL-6) in the last 72 hours after transfusion were analyzed by SPSS 26.0 and R software to evaluate clinical efficacy and transfusion safety. [Results] The baseline of the two groups was balanced after PSM (P>0.05). There was no significant difference in the total effective rate between the DRBC group (80.9%) and the SRBC group (86.5%) (P>0.05). In the SRBC group, WBC (×10 /L) increased from 9.634±6.742 to 10.147±6.835, CRP (mg/dL) increased from 5.468±4.647 to 6.174±6.114, and IL-6(pg/mL) decreased from 213.733±587.191 to 157.255±552.626. In the DRBC group, WBC (×10 /L) decreased from 11.123±7.880 to 11.011±8.549, CRP (mg/dL) decreased from 5.729±4.761 to 5.326±4.466, and IL-6(pg/mL) decreased from 238.806±639.060 to 152.255±266.558. Compared with the before treatment, the differences between the SRBC group and DRBC group were not statistically significant (P>0.05). Among all patients included in the statistics, the overall incidence of transfusion adverse reactions was 0.205% (6/2 916) in the SRBC group, and no adverse reactions occurred in the DRBC group. The incidence in the SRBC group was higher than that in the DRBC group. [Conclusion] Based on PSM analysis, there was no significant difference in the efficacy and safety of DRBC transfusion compared with SRBC transfusion, which can provide evidence-based support for routine application.

Objective : To investigate the effects of sinapine on lung tissue inflammation and mucus hypersecretion in asthmatic mice. Methods: Eight-week-old female C57BL/6J mice were randomly divided into Control group, ovalbumin(OVA) group, Sinapine group, and Sinapine+OVA group. The asthmatic mice model were established by intraperitoneal injection of OVA combined with aluminum hydroxide [Al(OH)3] suspension and OVA nasal stimulation. One hour before OVA nasal stimulation, the mice in Sinapine+OVA group and Sinapine group were intraperitoneally injected with sinapine solution, and the mice in OVA group and Control group were treated with the same dose of 0.9% sodium chloride solution. 24 hours after the last OVA stimulation, the inflammation of lung tissue of mice were observed by HE staining; the mucus secretion were evaluated by PAS staining; the mRNA expression levels of Interleukin-4(IL-4), Interleukin-5(IL-5), Interleukin-13(IL-13), tumor necrosis factor-alpha(TNF-α), Mucin 5ac(Muc5ac), and the mRNA of the key genes of Notch pathway such as Notch receptor 1(Notch1), Notch receptor 2(Notch2), Notch receptor 3(Notch3), and hes family bHLH transcription factor 1(Hes1) in lung tissues were detected by real-time fluorescent quantitative PCR(RT-qPCR); the expression levels of Notch1, Notch2, Notch3 and Hes1 proteins were determined by Western blot. Results : Compared with Control group, the inflammation score and PAS score of lung tissues of mice in OVA group increased(P<0.001); the mRNA expression levels of IL-4, IL-5, IL-13, TNF-α, and Muc5ac of mice in OVA group were enhanced(P<0.05); the mRNA and protein expression levels of Notch2, Notch3, and Hes1 of mice in OVA group significantly increased(P<0.001), while there was no significant difference in the mRNA and protein expression levels of Notch1. Compared with OVA group, the inflammation score and PAS score of lung tissues of mice in Sinapine+OVA group decreased(P<0.001); the mRNA expression levels of IL-4, IL-5, IL-13, TNF-α, and Muc5ac of mice in Sinapine+OVA group were reduced(P<0.05); the mRNA and protein expression levels of Notch2, Notch3, and Hes1 of mice in Sinapine+OVA group were downregulated(P<0.05), while there was no significant difference in the mRNA and protein expression levels of Notch1. Conclusion Sinapine can alleviate the lung tissue inflammation and mucus hypersecretion in asthmatic mice, and its mechanism may be related to the inhibition of Notch2/Notch3-Hes1 signal pathway.

Objective To evaluate the application of shear wave elastography(SWE)in the diagnosis of peripheral neuropathy in patients with diabetes.Methods Totally 85 patients with type 2 diabetes(T2DM)were selected from the Chengdu Office Hospital of People's Government of Tibetan Autonomous Region,including 46 patients with peripheral neuropathy(DPN)and 39 patients without peripheral neuropathy(NDPN).Compared for clinical data(gender,age,disease duration),cross-sectional area of the median nerve measured by high-frequency ultra-sound(CSA)and shear wave elastography(SWE)parameters(mean Young's modulus value,Emean)and shear wave velocity(SWV)between two groups of patients.Multifactor Logistic regression analysis was carried out on the indicators between the above groups to screen independent predictors in the diagnosis of peripheral neuropathy in diabetes patients,and a combined model was constructed.The area under the operating characteristic curve(AUC),sensitivity and specificity of the subjects were used to evaluate the diagnostic efficacy of the single model and com?bined model of the quantitative parameters(CSA,Emean,SWV)measured by clinical data,high?frequency ultra?sound and SWE in the diagnosis of peripheral neuropathy in diabetes patients.Results Age,course of disease,Emean,SWV and CSA were statistically significant in the diagnosis of peripheral neuropathy in diabetes patients(all P<0.05).AUC was 0.658,0.754,0.839,0.822 and 0.736,respectively.The combination model based on disease course,CSA and SWV showed the highest diagnostic efficiency,with AUC,sensitivity,and specificity of 0.887(0.800-0.946),80.43％,and 84.62％,respectively.Conclusions The combined model based on the course of disease,CSA and SWV have a high diagnostic efficiency in peripheral neuropathy of diabetes patients,and has good clinical application value.

Objective Using meta-analysis to identify the risk factors for slow-flow or no-reflow during percutaneous coronary intervention(PCI)in patients with ST-segment elevation acute myocardial infarction(AMI).Methods A computerized retrieval of academic papers concerning the risk factors for slow-flow or no-reflow during PCI in patients with ST-segment elevation AMI from the databases of CNKI,Wanfang Database,VIP,SinoMed,PubMed,Web of Science,Embase,and Cochrane Library was conducted.The retrieval time period was from the establishment of the database to January 2024.In order to ensure the accuracy and reliability of the study,two independent reviewers screened the literature according to the preset inclusion and exclusion criteria,extracted key data,and strictly evaluated the quality of the literature.RevMan5.4 software was used to make meta-analysis.Results A total of 23 articles with a total of 9 780 cases were included in this analysis.The results of meta-analysis showed that reperfusion time ≥6 h(OR=1.52),preoperative TIMI blood flow≤level-Ⅰ(OR=1.12),heavy thrombus burden(OR=1.60),advanced age(OR=1.56),diabetes(OR=1.83),preoperative Killip grade≥Ⅲ(OR=2.52),long target vessel disease(OR=1.95),and collateral flow≤level-Ⅰ(OR=1.61)were the risk factors for slow-flow or no-reflow during PCI in patients with ST-segment elevation AMI.Preoperative systolic blood pressure＜90 mmHg(OR=1.17)and high white blood cell(WBC)count(OR=1.27)were not the risk factors for slow-flow or no-reflow during PCI in patients with ST-segment elevation AMI.Conclusion Reperfusion time ≥ 6 h,preoperative TIMI blood flow≤level-Ⅰ,heavy thrombus burden,advanced age,diabetes,preoperative Killip grade≥level-Ⅲ,long target vessel lesion,and collateral blood flow≤level-Ⅰ are the independent risk factors for slow-flow or no-reflow during PCI in patients with ST-segment elevation AMI.

Objective To evaluate the efficacy of human papillomavirus E6/E7(HPV E6/E7)mRNA combined with colposcopy in screening cervical cancer and precancerous lesions.Methods A total of 480 patients with suspected cervical precancerous lesions in the hospital from July 2022 to De-cember 2024 were retrospectively selected as research objects.All the patients underwent HPV E6/E7 mRNA testing,colposcopy,and pathological examination.Taking the pathological examination results as the diagnostic golden standard,the diagnostic values of HPV E6/E7 mRNA and colposcopy alone as well as their combination were analyzed.Results The pathological examination results of 480 pa-tients showed that there were 192 negative cases,including 1 case of normal cervix and 191 cases of benign lesions;there were 288 positive cases,including 133 cases of low-grade squamous intraepithe-lial lesions(LSIL),110 cases of high-grade squamousintraepithelial lesions(HSIL),and 45 cases of cervical squamous cell carcinoma(SCC).The colposcopy results showed 211 true-positive cases and 138 true-negative cases;the HPV E6/E7 mRNA test results showed 199 true-positive cases and 137 true-negative cases;the combined test results showed 239 true-positive cases and 174 true-negative cases.The sensitivity(95.22％),specificity(75.98％),accuracy(86.04％),positive predic-tive value(81.29％),and negative predictive value(93.55％)of the combined test were signifi-cantly higher than those of each individual test(P＜0.001).Moreover,the consistency between the combined test and pathological results(Kappa=0.718,P＜0.001)was also significantly high-er than that of each individual test.Conclusion Compared with HPV E6/E7 mRNA or colposcopy alone,the combined test has higher clinical application value in screening of cervical precancerous lesions and cervical cancer,shows stronger consistency with pathological results,and is of great sig-nificance for the early differential diagnosis of cervical precancerous lesions and cervical cancer.

Objective: To investigate the role of transcription factor EB (TFEB) -autophagy pathway in rifampicininduced liver injury and its possible mechanism. Methods: Forty 6-8-week-old C57/BL6 mice were randomly divided into five groups : control group , model group , TFEB low-dose agonist group , TFEB high-dose agonist group , and autophagy agonist group , with 8 mice in each group. Except for the control group , the other four groups were given rifampicin 200 mg/(kg ·d) by gavage daily. TFEB agonist was administered intraperitoneally at a low dose of 20 mg/kg and a high dose of 50 mg/kg for 7 days at 1 h after rifampicin administration. Autophagy agonist was administered by gavage at a dose of 10 mg/kg 6 h before rifampicin administration on day 1 . The experiment was completed 7 days after modeling. The degree of liver injury was evaluated by detecting liver function indexes and liver pathological changes. Western blot was used to detect the protein expression total TFEB , chelator 1( p62) , microtubule-associated protein light chain 3(LC3) , benzyl chloride 1(Beclin-1) , sodium taurocholate co-transporting polypeptide(NTCP) and bile salt export pump(BSEP) levels in liver nucleus/liver tissue were quantified. Results: Compared with the control group , the serum levels of alanine aminotransferase ( ALT) , aspartate aminotransferase (AST) , total bilirubin ( TBIL) , direct bilirubin ( DBIL) , and total bile acid ( TBA) in the model group increased (P < 0. 05) , and obvious pathological changes were observed in the liver. Compared with the model group , the high dose and low dose of TFEB agonist and autophagy agonist groups had reductions in the above indicators (P < 0. 05) . Compared with the low-dose TFEB agonist group , the high-dose TFEB agonist group had reductions in the above indicators (P < 0. 05) . The proportion of TFEB in the nucleus was ( 1. 0 ± 0. 10) in the control group , (0. 6 ± 0. 05) in the model group , (0. 8 ± 0. 08) in the low-dose agonist group , and (0. 9 ± 0. 07) in the high-dose agonist group (P < 0. 05) . Autophagy agonist group (0. 7 ± 0. 06) (P < 0. 05) . Compared with the control group , the levels of NTCP and BSEP in the liver of the model group decreased (P < 0. 05) , and the expression of NTCP and BSEP in the TFEB low-dose and high-dose agonist groups were restored , and the expression of NTCP and BSEP in the autophagy agonist group also increased (P < 0. 05) . Compared with the control group , the protein expression levels of TFEB , LC3- Ⅱ/LC3- Ⅰand Beclin-1 in the liver tissue of the model group significantly decreased (P < 0. 05) , while the protein expression level of p62 significantly increased ( P < 0. 05) . Compared with the model group , the protein expression levels of TFEB , LC3- Ⅱ/LC3- Ⅰand Beclin-1 in the liver tissue of the TFEB agonist high-dose group , low-dose group and autophagy agonist group increased (P < 0. 05) , while the protein expression level of p62 decreased (P < 0. 05) . Conclusion TFEB can improve rifampicin-induced liver injury by activating autophagy pathway , and the main mechanism may be related to the up-regulation of NTCP and BSEP expression.

Objective:To investigate the clinicopathological and genetic characteristics of monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL).Methods:The forty-two MEITL cases diagnosed in the Department of Pathology, Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine, Shanghai, China from 2016 to 2022 was retrospectively analyzed. Clinical data were collected, and follow-up was performed. Morphological characteristics were observed. Immunohistochemistry, Epstein-Barr virus (EBV) in situ hybridization, clonal rearrangement analysis of T-cell receptor (TCR) genes, and targeted next-generation sequencing (NGS) were performed.Results:Among the 42 patients (male/female ratio of 2.8∶1.0), the age range was 32-77 years with a median age of 59.5 (52.0-65.0) years. Grossly, the tumors were presented as ulcerative or exophytic lesions, with a maximum diameter of 2-18 cm. There were 34 cases with a single lesion and 8 cases with more than 1 lesion. The tumor cells in all 42 cases were relatively monotonous in histology and small or medium in size. They had round or oval nuclei, moderately pale or clear cytoplasm, evenly distributed nuclear chromatin, inconspicuous nucleoli, and frequent mitotic figures. In one of the cases, there were moderately large cells, vacuolated nuclei, and clear nucleoli. Lymphoepithelial lesions were observed in 36 (85.7%) of the 42 cases, tumor necrosis in 4 (9.5%) cases, scattered eosinophils and/or plasma cell infiltration in the background in 9 (21.4%) cases, and a "starry sky" phenomenon in 1 (2.4%) case. The tumor cells in all cases exhibited high expression of CD3, CD2, CD7, CD8, CD56, TIA1, Granzyme B, and Perforin, while some also expressed CD4 (5/41, 12.2%), CD5 (3/41, 7.3%), CD20 (4/41, 11.9%), CD79α (2/37, 5.4%), and CD30 (1/34, 2.9%). The Ki-67 proliferation index ranged from 40% to 90%. EBER in situ hybridization tests were negative in all cases. TCR gene clonal rearrangement was detected in 96.4% (27/28) of the tested cases. Targeted NGS revealed commonly mutated genes including SETD2, STAT5B, JAK3, TP53, and CREBBP. The primary treatment was chemotherapy, with 2 cases undergoing autologous hematopoietic stem cell transplantation. Follow-up information was obtained for 29 cases, with a follow-up period of 1-73 months. The mortality was 93.1% (27/29).Conclusions:MEITL is a rare and highly aggressive peripheral T-cell lymphoma. Its clinical manifestations are diverse, and diagnosis primarily relies on a comprehensive assessment of pathological morphology, immunohistochemical profiles, and EBV infection status, supplemented by genetic testing if necessary. At present, there is no effective treatment, and its overall prognosis is poor.
