Objective:To investigate the effects of musculoskeletal ultrasound(MSUS)-guided shoulder joint capsule hydraulic expansion method combined with rotator interval(RI)injection method on ultrasound imaging indicators,shoulder function,and serum inflammatory factors in treating patients with early primary frozen shoulder(PFS).Methods:A total of 168 patients with early PFS admitted to Jiangbei District of The Frist Affiliated Hospital to Army Medical University between June 2021 and June 2023 were selected.They were randomly divided into a control group and an observation group by using a random number table,with 84 patients in each group.The control group received the therapy with MSUS-guided shoulder joint capsule hydraulic expansion.The observation group received the therapy with RI injection on the basis of the control group.After 5 weeks of treatment,the changes of the following parameters were compared and analyzed between the two groups:Visual Analog Scale(VAS)score for shoulder pain,Simple Shoulder Test(SST)score,Constant-Murley Score(CMS),thickness of the glenohumeral joint capsule at the axilla of ultrasound imaging,thickness of coracohumeral ligament(CHL),RI thickness,positivity rate of RI blood flow,passive range of motion(ROM)of the shoulder joint,and serum inflammatory factor levels including tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)and interleukin-6(IL-6).Results:At 5th week after treatment,both groups showed VAS scores decreased,and SST and CMS scores increased.The VAS score(1.34±0.30)of observation group was significantly lower than(1.97±0.46)of control group,and the SST score and CMS score were significantly higher than those of control group(t=10.514,9.597,7.910,P<0.05),respectively.Both groups showed decreases in thickness of the glenohumeral joint capsule at the axilla,CHL thickness,RI thickness,and positivity rate of RI blood flow,and these indicators of observation group were significantly lower than them of control group,with statistically significant differences(t=5.518,16.106,9.050,25.211,P<0.05).The ranges of backward extension and outward rotation of observation group were larger than those of control group,and the differences were statistically significant(t=9.209,12.447,P<0.05).The serum levels of TNF-α,IL-6 and CRP of observation group were significantly lower than those of control group,and the differences were statistically significant(t=10.523,17.750,19.995,P<0.05),respectively.Conclusion:The treatment of MSUS-guided shoulder joint capsule hydraulic expansion combined with RI injection can effectively alleviate the degrees of shoulder pain and dysfunction in patients with early PFS,and improve indicators of ultrasound imaging,the ROM values of outward rotation and backward extension,and reduce serum levels of inflammatory factors,which have favorable therapeutic effects.

BACKGROUND: Neoadjuvant chemoradiotherapy followed by radical surgery has been a common practice for patients with locally advanced rectal cancer, but the response rate varies among patients. This study aimed to develop a ResNet-Vision Transformer based magnetic resonance imaging (MRI)-endoscopy fusion model to precisely predict treatment response and provide personalized treatment. METHODS: In this multicenter study, 366 eligible patients who had undergone neoadjuvant chemoradiotherapy followed by radical surgery at eight Chinese tertiary hospitals between January 2017 and June 2024 were recruited, with 2928 pretreatment colonic endoscopic images and 366 pelvic MRI images. An MRI-endoscopy fusion model was constructed based on the ResNet backbone and Transformer network using pretreatment MRI and endoscopic images. Treatment response was defined as good response or non-good response based on the tumor regression grade. The Delong test and the Hanley-McNeil test were utilized to compare prediction performance among different models and different subgroups, respectively. The predictive performance of the MRI-endoscopy fusion model was comprehensively validated in the test sets and was further compared to that of the single-modal MRI model and single-modal endoscopy model. RESULTS: The MRI-endoscopy fusion model demonstrated favorable prediction performance. In the internal validation set, the area under the curve (AUC) and accuracy were 0.852 (95% confidence interval [CI]: 0.744-0.940) and 0.737 (95% CI: 0.712-0.844), respectively. Moreover, the AUC and accuracy reached 0.769 (95% CI: 0.678-0.861) and 0.729 (95% CI: 0.628-0.821), respectively, in the external test set. In addition, the MRI-endoscopy fusion model outperformed the single-modal MRI model (AUC: 0.692 [95% CI: 0.609-0.783], accuracy: 0.659 [95% CI: 0.565-0.775]) and the single-modal endoscopy model (AUC: 0.720 [95% CI: 0.617-0.823], accuracy: 0.713 [95% CI: 0.612-0.809]) in the external test set. CONCLUSION The MRI-endoscopy fusion model based on ResNet-Vision Transformer achieved favorable performance in predicting treatment response to neoadjuvant chemoradiotherapy and holds tremendous potential for enabling personalized treatment regimens for locally advanced rectal cancer patients.

Objective To explore the guiding value of thromboelastography(TEG)in blood transfusion therapy for patients undergoing liver rupture repair.Methods A total of 106 patients who underwent liver rupture repair and were admitted to the hospital from June 2021 to June 2024 were selected.According to the random number table method,the patients were divided into 53 patients who underwent liver rupture repair with TEG detection blood transfusion(study group)and 53 patients who underwent liver rupture repair with conventional coagulation function detection blood transfusion(control group).General information of patients was collected.The levels of coagulation function indicators,the dosage of blood products and intraoperative complications of patients in the study group and the control group before blood transfusion and 24 hours after blood transfusion were compared.Results 24 hours after blood transfusion,the fibrinogen level in the study group was higher than that in the control group,while the prothrombin time,activated partial thromboplastin time and thrombin time were shorter than those in the control group,and the differences were statistically sig-nificant(P<0.05).The dosages of red blood cells,frozen plasma,platelets and cryoprecipitate in the study group were all lower than those in the control group,and the differences were statistically significant(P<0.05).The total incidence of intraoperative complications in the study group was lower than that in the con-trol group,and the difference was statistically significant(P<0.05).Conclusion TEG has significant guiding value in blood transfusion therapy for patients undergoing liver rupture repair.

MicroRNA(miRNA)serves as a novel regulatory factor in viral and bacterial co-infections,exhibiting dual regulatory roles during pathogen infections.On the one hand,it exerts protective effects by modulating viral replication cycles and host anti-infection immune responses.On the other hand,it can be exploited by pathogens to promote infection progression,including influencing viral replication,antiviral immune responses,and regulating bacterial adhesion and proliferation.Mixed viral and bacterial infections lead to high mortality rates.By binding to specific target gene mRNA,miRNA degrades or inhibits its translation,thereby regulating target gene expres-sion,which may ultimately serve as potential diagnostic and therapeutic targets.This paper reviews recent ad-vances in research on the role of miRNA in viral and bacterial infections,particularly its mechanisms in co-infec-tions,aiming to provide theoretical reference for further research on the infection mechanisms.

[Purpose]To analyze the diagnostic yield of quantitative fecal immunochemical test(FIT)at different cut-offs in colorectal cancer(CRC)screening.[Methods]The sequential screening method was adapted in Jiashan CRC screening program for local residents aged 40～74 years old,which included a quantitative FIT and high-risk factor questionnaire for primary screening and subsequent colonoscopy for the diagnostic screening.Subjects who participated in quantitative FIT were included in this study between September,2021 and August,2023.The positive predictive values(PPVs)for colorectal neoplasms were calculated at the cut-offs of 100,120,140,160,180 and 200 ng/mL of FIT.The Cochran-Armitage trend test was performed to compare the trend of PPVs at different cut-offs.The effects of different starting age and FIT cut-offs on requirement of colonoscopy and advanced neoplasia detection were assessed.[Results]A total of 58 256 individuals completed the quantitative FIT,and 3 106 had fecal hemoglobin concentrations＞100 ng/mL,among whom 2 186 underwent colonoscopic examination with a compliance rate of 70.38％.The colonoscopy detected 588 cases of non-advanced adenomas and 355 cases of advanced neoplasms(AN),in-cluding 30 cases of CRC and 325 cases of advanced adenomas.Progressively increasing the cut-off showed a decrease in PPVs of non-advanced adenomas and an increase of AN.The ratio of the rate of reduced requirement of colonoscopy to the missed rate of the progressive lesions was the smallest when the screening start age was 45 years old and the positive FIT threshold was set at 100 ng/mL.[Conclusion]There were significant differences in the diagnostic yield at different cut-offs of FIT.Increasing the cut-offs of FIT will elevate PPVs for the advanced neoplasms.
