OBJECTIVES: To evaluate the clinical efficacy of hospital-prepared Chinese medicine Feigan granules for influenza patients. This study has been registered at the International Traditional Medicine Clinical Trial Registry platform (ITMCTR2025000162). METHODS: A prospective observational study was conducted on influenza patients who visited the Fever Clinic of the First Affiliated Hospital, Zhejiang University School of Medicine between February and March 2024. Patients were divided into the observation group (Feigan granules combined with conventional Western medicine) and the control group (conventional Western medicine). Main symptoms (including fever, cough and sore throat) and secondary symptoms (including chest tightness, poor appetite, muscle soreness and dry mouth) were evaluated with traditional Chinese medicine (TCM) symptom scale on the first day of the patient's visit and the third day after treatment. The degrees of improvement in the TCM symptom scores before and after treatment were compared using paired rank-sum test, and the differences in the overall symptom efficacy index between two groups were compared using the Wilcoxon test. RESULTS: A total of 217 influenza patients were included. After treatment, the TCM symptom scores of both groups were significantly improved compared with those before treatment (all P<0.01). The median differences in the main symptom score before and after treatment in the observation and the control groups were 7 points (95%CI: 6.0-8.0) and 6 points (95%CI: 6.0-8.0), respectively. The median difference in the secondary symptom score was 3 points (95%CI: 2.0-4.0) in both groups. The median differences in the total score were 9 points (95%CI: 8.0-10.5) and 8 points (95%CI: 7.0-10.0) in the observation and control groups, respectively. In the subgroup with an initial cough score >2, the improvement rates of total score (97.06% vs. 92.59%) and secondary symptoms (92.31% vs. 85.11%) in observation group were significantly higher than those in the control group (P<0.05); while there was no significant difference in the improvement rate of the main symptoms (95.59% vs. 90.74%, P>0.05). CONCLUSIONS Feigan granules can improve the TCM syndromes of influenza patients, especially for patients with more severe cough.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.

OBJECTIVE To investigate the intervention effect and potential mechanism of breviscapine on hepatic fibrosis （HF） in rats based on the transforming growth factor-β（1 TGF-β1）/Smad2/extracellular signal-regulated protein kinase 1（ERK1） and Kelch-like epichlorohydrin-associated protein 1（Keap1）/nuclear factor-erythroid 2-related factor 2（Nrf2）/heme oxygenase-1（HO-1） pathways. METHODS Totally 60 rats were randomly divided into normal control group， model group， breviscapine low-dose， medium-dose and high-dose groups （5.4， 10.8， 21.6 mg/kg）， and colchicine group （positive control， 0.45 mg/kg）， with 10 rats in each group， half male and half female. Except for the normal control group， HF model of the other groups was induced by carbon tetrachloride. Subsequently， each drug group was given corresponding medicine by gavage once a day for 28 days. The liver appearance of rats in each group was observed and their liver coefficients were calculated. The levels of alanineaminotransferase （ALT） and aspartate aminotransferase （AST）in serum， those of ALT， AST， superoxide dismutase （SOD），malondialdehyde （MDA） and glutathione peroxidase （GSH- Px） in liver tissue were detected. The liver tissue inflammatory and fibrotic changes were observed. The protein and mRNA expressions of TGF-β1， Smad2， ERK1， Nrf2， Keap1 and HO-in liver tissue were detected. RESULTS Compared with the normal control group， the model group showed large areas of white nodular lesions in the liver， obvious inflammatory cell infiltration and collagen fiber deposition. The body weight， the levels of SOD and GSH-Px in liver tissue， the protein and mRNA expressions of Nrf2 and HO-1 were significantly lowered in the model group （P＜0.05）； the liver coefficient， the percentage of Masson staining positive area， ALT and AST levels of serum and liver tissue， MDA level of liver tissue， the protein and mRNA expressions of TGF-β1， Smad2， ERK1 and Keap1 were significantly increased （P＜0.05）. Compared with the model group， the liver lesions of rats in each drug group were improved， and the above quantitative indexes were generally reversed （P＜0.05）. CONCLUSIONS Breviscapine has a good intervention effect on HF rats， which may be related to inhibiting TGF-β1/Smad2/ERK1 pathway for anti-fibrosis and regulating Keap1/Nrf2/HO-1 pathway to inhibit oxidative stress.

The self-care behaviors with arteriovenous fistula and other observation indexes between the two groups were compared.Results:There were 23 males and 22 females in the control group, aged (58.07 ± 3.00) years old. There were 24 males and 21 females in the experimental group, aged (58.93 ± 4.07) years old. After care, the total internal fistula self-care behaviour score in the experimental group was (49.44 ± 1.84) points, and (38.93 ± 2.19) points in the control group, the difference between the two groups were statistical significant ( t = 24.65, P<0.05). For health management adherence, the score of fluid intake, dialysis regimen, medication and dietary dimension were (15.82 ± 1.37), (12.87 ± 1.39), (17.24 ± 1.33) and (21.60 ± 1.03) points in the experimental group, and (11.20 ± 0.92), (9.98 ± 1.14), (12.11 ± 1.01) and (17.40 ± 1.10) points in the control group, the difference between the two groups were statistical significant ( t values were 10.78 to 20.62, all P<0.05). For positive psychological capital, the scores of self-efficacy, resilience, hope and optimism were (38.69 ± 1.22), (39.27 ± 1.10), (33.29 ± 1.52) and (33.40 ± 1.39) points, and were (31.16 ± 1.26), (31.04 ± 1.15), ( 26.13 ± 1.52) and (27.09 ± 7.28) points in the control group, the difference between the two groups were statistical significant ( t values were 5.71 to 34.77, all P<0.05). The total complication rate of the experimental group was 8.89% (4/45), lower than 28.89% (13/45) in the control group, and the differences were all statistically significant ( χ2 = 5.87, P<0.05). Conclusions:The combined application of micro-video breakthrough education and special workshops in maintenance hemodialysis patients with internal fistula is beneficial to the improvement of their internal fistula self-care ability, health management compliance and positive psychological capital, and can reduce the probability of internal fistula complications.

Objective To investigate the reversal effect and mechanism of cinobufagin(CBG)on cisplatin resist-ance in human ovarian cancer cells.Methods A2780 cell line and its cisplatin-resistant cell line A2780/DDP are common ovarian cancer cells in clinic,so these two cell lines were selected as the research objects.The cell viabil-ity was detected by cell Counting Kit-8(CCK-8)assay,and the cell proliferation ability was detected by plate clo-ning and 5-ethynyl-2′-deoxyuridine(EdU)assay.Hoechst staining was used to observe cell apoptosis.Cell scratch test and Transwell test were used to evaluate cell migration and invasion ability.Western blot and quantitative reverse transcription PCR(RT-qPCR)were used to detect the protein and mRNA expressions of phosphatidylinosi-tol 3-kinase/protein kinase(PI3K/AKT)signaling pathway and epithelial-mesenchymal transition(EMT).Re-sults Compared with A2780 cells,the drug resistance indexes of A2780/DDP cells were 5.636,5.864,5.695,respectively.After treatment of A2780/DDP cells with CBG(2,4,6 mg/ml),the reversal resistance indexes were 1.617,2.570,3.461,respectively.CBG treatment significantly increased the level of apoptosis and inhibi-ted the proliferation,migration and invasion of the cells in a concentration-dependent manner(P<0.05).Western blot results showed that compared with A2780 cells,the relative ratio of P-PI3K/PI3K and P-AKT/AKT protein levels,as well as the protein expression of N-cadherin,Vimentin,and Snail were higher in the control group(A2780/DDP)cells,while the protein expression of E-cadherin was lower(tP-PI3K/PI3K=8.115,tP-AKT/AKT=17.62,tN-cadherin=6.126,tVimentin=4.001,tSnail=17.333,tE-cadherin=4.620,P<0.01);As the dose of CBG increased,the protein expression levels of P-PI3K,P-AKT,N-cadherin,Vimentin,and Snail in drug-resistant cells de-creased,while the protein expression level of E-cadherin increased(FP-PI3K=268.5,FP-AKT=190.5,FN-cadherin=24.02,FVimentin=57.65,FSnail=87.24,FE-cadherin=135.8,P<0.05).qRT-PCR results showed that with the in-crease of CBG concentration,the mRNA expression levels of PI3K,AKT,N-cadherin,Vimentin and Snail de-creased,while the mRNA expression level of E-cadherin gradually increased(FPI3K=101.1,FAKT=558.3,FN-cadherin=86.97,FVimentin=105.9,FSnail=85.71,FE-cadherin=80.96,P<0.01).Conclusion CBG can reverse cisplatin resistance of ovarian cancer A2780/DDP cell line,and its mechanism may be related to the regulation of PI3K/AKT signaling pathway and inhibition of EMT by CBG.

Objective To observe the impact of ultrasonic image quality on the consistency of artificial intelligence(Al)assisted diagnosis system and manual measurements of biological indicators of developmental dysplasia of hip(DDH).Methods Hip ultrasonic data of 75 DDH and 345 non-DDH children were retrospectively analyzed,and the quality of ultrasonic images were subjectively scored.An evaluation model of ultrasonic image quality was constructed based on 140 ultrasonic images acquired from 140 cases(group A,containing 25 DDH and 115 non-DDH)using entropy weighting method,the weight of anatomic structures and impact factors related to DDH were obtained.The comprehensive image quality scores of other ultrasonic images acquired from 280 cases(group B,including 50 DDH and 230 non-DDH)were calculated,and the images in group B were classified into grade A,B and C in descending order.The consistency of AI and manual measurements of DDH biological indicators in group B was assessed.Results The weight of each anatomic structure and impact factors of DDH obtained with the model were as follows:The lower edge of iliac branch＞ilium＞glenoid labrum＞bony margin＞femoral head＞motion artifacts.In group B,grade A was observed in 67(9 DDH and 58 non-DDH),grade B was found in 160(26 DDH and 134 non-DDH),while grade C was noticed in 53(15 DDH and 38 non DDH)images.Except for β,femoral head coverage(FHC)and femoral head length diameter,the consistencies between AI and manual measurements of other indicators of DDH were grade A＞B＞C.In group B,AI and manual measurements were more consistent in DDH than in non-DDH cases.Conclusion Ultrasonic image quality affected the consistency between AI and manual measurements of biological indicators of DDH.When image quality was not good enough,further attention should be paid to measurement of FHC and sizes of femoral head.

The efficient clinical treatment of oral squamous cell carcinoma(OSCC)is still a challenge that demands the development of effective new drugs.Phenformin has been shown to produce more potent anti-tumor activities than metformin on different tumors,however,not much is known about the influence of phenformin on OSCC cells.We found that phenformin suppresses OSCC cell proliferation,and promotes OSCC cell autophagy and apoptosis to significantly inhibit OSCC cell growth both in vivo and in vitro.RNA-seq analysis revealed that autophagy pathways were the main targets of phenformin and identified two new targets DDIT4(DNA damage inducible transcript 4)and NIBAN1(niban apoptosis regulator 1).We found that phenformin significantly induces the expression of both DDIT4 and NIBAN1 to promote OSCC autophagy.Further,the enhanced expression of DDIT4 and NIBAN1 elicited by phenformin was not blocked by the knockdown of AMPK but was suppressed by the knockdown of transcription factor ATF4(activation transcription factor 4),which was induced by phenformin treatment in OSCC cells.Mechanistically,these results revealed that phenformin triggers endoplasmic reticulum(ER)stress to activate PERK(protein kinase R-like ER kinase),which phosphorylates the transitional initial factor eIF2,and the increased phosphorylation of eIF2 leads to the increased translation of ATF4.In summary,we discovered that phenformin induces its new targets DDIT4 and especially NIBAN1 to promote autophagic and apoptotic cell death to suppress OSCC cell growth.Our study supports the potential clinical utility of phenformin for OSCC treatment in the future.

Objective Based on the limited time theory,taking tonsillectomy day operation as an example,the whole process nursing list of day operation was constructed,and its application effect was evaluated.Methods The nursing service list of tonsillectomy was constructed based on literature research,field observation and expert correspondence.A total of 197 patients who underwent tonsillectomy in the day ward of a tertiary A general hospital in Hangzhou,Zhejiang Province were selected.Among them,98 patients from April to June 2023 were taken as an experimental group and treated with the whole-process nursing list of daytime tonsillectomy constructed in this study,and 99 patients from January to March 2023 were taken as a control group and routine nursing was adopted.The anxiety degree,postoperative pain score,postoperative complication rate and patients'satisfaction with nursing service were compared between the 2 groups.Results Anxiety scores before operation and at discharge,pain scores at 6 h,12 h and 24 h after operation,and incidence of complications such as infection and gastrointestinal reaction within 14 days after operation in the experimental group were lower than those in the control group,with statistical significance(P＜0.05).The satisfaction of nursing service in the experimental group(99.40±0.69)score was significantly higher than that in the control group(90.36±1.04)score,and the difference was statistically significant(P＜0.001).Conclusion The use of tonsillectomy day whole-process nursing list can improve perioperative anxiety,relieve postoperative pain and reduce the incidence of postoperative complications,and improve patient satisfaction.

Objective:To establish a multiplex detection method for monitoring viruses post-kidney transplantation based on droplet digital PCR (ddPCR) technology, evaluate its detection performance, and discuss its potential clinical application.Methods:We developed a ddPCR assay for the simultaneous detection of polyomavirus type 1 virus (BKV), polyomavirus type 2 virus (JCV), and torque teno virus (TTV), assessing its conformity rate, repeatability, and detection limit. 69 clinical urine samples were collected at the Shanghai Jiao Tong University School of Medicine affiliated with Renji Hospital between June and September 2023. The qPCR and ddPCR methods were employed to analyze the results, respectively. Spearman correlation analysis, Bland-Altman analysis, and Wilcoxon paired rank sum test were applied to analyze the detection results of the two methodologies.Results:The constructed ddPCR method had a 7/7 concordance rate for the seven reference samples. The precision reference samples were tested ten times, respectively, and their coefficients of variation were less than 10%. The detection limit was 10 copies/μl. The concordance rates of ddPCR and qPCR for BKV and JCV detection were more than 95% (66/69, 68/69). The correlation coefficients (R) of BKV and JCV viral loads were 0.874 and 0.840, respectively. The Bland-Altman analysis showed that the mean differences in BKV and JCV viral load detection between the two methods were -0.34 and -0.187, respectively. The Wilcoxon paired rank sum test showed that there were no statistically significant differences in the detection results of polyomaviruses between the two methods ( P>0.05). Conclusion:A ddPCR-based multiplex detection method for viruses post-renal transplantation was successfully developed, confirming its superior attributes of high accuracy, high sensitivity, and multi-detection capability. This method could be used for the quantitative detection of BKV, JCV, and TTV in clinical urine samples.
