OBJECTIVE To introduce the development of an intelligent prescription review decision-support system for anti-tumor drugs and assess its clinical application outcomes. METHODS Relevant data sources， including national and local pharmaceutical administration policies， clinical practice guidelines/consensus， hospital information systems data， and genetic testing results， were integrated. Adhering to the principles of structure， standardization and dynamic updating， a knowledge base covering chemotherapeutic， targeted and immunotherapeutic agents was constructed using a dual-dimensional modeling approach that combined “drug attributes” and “clinical contexts”. This knowledge base was then embedded into the hospital’s electronic medical order system to establish the prescription review decision-support system. The application and performance of the system were evaluated at Shanghai Sixth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. RESULTS A knowledge base containing 18 318 prescription review rules for anti-tumor drugs was constructed， and a closed-loop prescription review system was successfully established， encompassing pre-prescription real-time intervention， in-process interactive review， and post-prescription evaluation and analysis. From 2021 to 2024， the system generated a total of 57 879 alerts for prescriptions of five typical categories of anti-tumor drugs. For platinum-containing prescriptions， 22 577 alerts were generated， with Cisplatin for injection （lyophilized） being the most frequently alerted drug （13 445 alerts）， and “ototoxicity risk due to combined use” alerts remained high （7 682 alerts）. For methotrexate-containing prescriptions， 3 721 alerts were recorded， primarily related to “precaution-related issues” （76.4%， 2 843/3 721）. For doxorubicin-containing prescriptions， 17 301 alerts were triggered， primarily related to “dosage and administration” （14 315 alerts）. For human epidermal growth factor receptor 2-targeted agents-containing prescriptions， 1 007 alerts were issued， mostly related to “reimbursement restrictions” （956 alerts）. For programmed death-1/programmed death-ligand 1 inhibitors-containing prescriptions， the alerts increased year by year， totaling 13 273 alerts， primarily related to “inappropriate indication” （9 118 alerts）. Over the 4 years， the physician response rates to system alerts were 21.4%， 27.1%， 33.5% and 51.6%， respectively. CONCLUSIONS An intelligent decision-support system for anti-tumor drug prescription review， encompassing a closed-loop process of “real-time pre-event intervention， interactive in-event prescription review， post-event evaluation and analysis”， has been successfully constructed and implemented throughout the entire workflow. There is a discernible trend in this hospital， where the focus on monitoring anti-tumor drugs is shifting towards immunotherapy drugs. Additionally， the acceptance rate of physicians regarding prescription review opinions has been steadily increasing year by year.

Objective To compare the technical indicators and clinical effect of catheter-directed thrombolysis(CDT)via two types of non-popliteal venous access in the treatment of acute mixed-type lower extremity deep vein thrombosis(DVT).Methods The clinical data of 119 patients with acute mixed-type lower extremity DVT,who were admitted to the Affiliated Jiangning Hospital of Nanjing Medical University and the Affiliated Nanjing Hospital of Nanjing Medical University of China to receive CDT treatment from January 2016 to June 2022,were retrospectively analyzed.Of the 119 patients,CDT via deep calf vein access was carries out in 45(calf vein group)and CDT via healthy-side femoral venous access was performed in 74(femoral vein group).The success rate of vascular puncture,success rate of catheterization technique,number of successful CDT venous puncturing,time spent for sheath placement,time spent for catheterization,thrombolysis time,used amount of thrombolytic agent and associated complications(including vein puncturing and anticoagulant thrombolysis-related complications),the thrombolytic effect of different anatomical segments,and the clinical efficacy during the follow-up period for at least 12 months were compared between the two groups.Results Successful catheterization via deep calf vein access and via healthy-side femoral vein access was obtained in 31 and 58 CDT patients respectively,with a technical success rate of 68.89％(31/45)and 78.38％(58/74)respectively,the difference between the two groups was not statistically significant(P=0.248).In 26 patients(67.74％)of the calf vein group,more than two times of puncturing were needed before the sheath placement could be successfully achieved.The time spent for sheath placement in the femoral vein group was(1.84±0.87)min,which was remarkably shorter than(10.52+6.13)min in the calf vein group(P＜0.001),but the time spent for catheterization in the femoral vein group was(41.60±13.31)min,which was obviously longer than(20.06+4.46)min in the calf vein group(P＜0.001).The thrombolysis time in the femoral vein group and the calf vein group was(5.34+1.43)days and(5.06±1.18)days respectively(P=0.354),and the used amount of thrombolytic agent in the femoral vein group was(352.16±71.98)×104 U,which was prominently larger than(284.68±77.64)× 104 U in the calf vein group(P＜0.001).The last follow-up check showed that the patency rate of the popliteal vein in the calf vein group was significantly higher than that in the femoral vein group(P=0.037).No statistically significant differences in the incidence of post-thrombotic syndrome(PTS)and the mean VEINES-QOL/Sym scores existed between the two groups(all P＞0.05).Conclusion Compared with CDT via healthy-side femoral vein access,CDT via deep calf vein access can better remove the thrombus in the popliteal vein and superficial femoral vein,and improve the femoropopliteal vein patency rate,although it has no obvious advantages in reducing the occurrence of PTS and in improving the VEINES-QOL/Sym score,moreover,the deep calf vein puncture and sheath placement require a high-level technique.

Objective:To compare the clinical efficacy of catheter-directed thrombolysis (CDT) via the contralateral femoral vein approach (CFVA-CDT) and the calf deep vein approach (CVA-CDT) in the treatment of acute mixed-type lower extremity deep vein thrombosis (DVT).Methods:Patients treated with CFVA-CDT and CVA-CDT for acute mixed-type DVT were retrospectively collected from January 2018 to December 2021, totaling 49 and 32 patients, respectively. The relevant technical indicators, thrombolysis rates in the iliac-femoral vein segment and femoral-popliteal vein segment, clinical efficacy, and the incidence of lower extremity deep vein patency, venous valve insufficiency, and post-thrombotic syndrome (PTS), as well as the severity of chronic venous disease in the affected limb (VCSS score) during a 2-year follow-up period were retrospectively compared between the two venous access CDT groups. The t-test was used for comparing quantitative data, while the chi-square test or Fisher′s exact test was used for categorical data.Results:During CFVA-CDT procedure, 6-8 F vascular sheaths were used, and balloon dilation of 2~6 mm was more frequently employed (65.31%, 32/49) to expand venous stenosis/occlusion segments before successful sheath placement compared to the CVA-CDT group (37.50%, 12/32), and the difference was statistically significant ( P=0.014). In the CVA-CDT group, 31.25% (10/32) of patients had a maximum sheath size of 6 F, while the remainder used 4 or 5 F sheaths. Among them, 34.38% (11/32) of patients required re-puncture of the popliteal or femoral vein for larger sheaths (≥8 F) for thrombus aspiration and subsequent endovascular treatment during or after thrombolysis. The effective thrombolysis rates (≥50%) in the iliac-femoral vein segment were not significantly different between the two groups ( P=0.778). The effective thrombolysis rate of the femoral-popliteal venous segment is related to the presence or absence of popliteal vein opacification on lower extremity venous antegrade venography. There was no significant difference between the groups when the popliteal vein was visualized ( P=1.000). While the popliteal vein was not visualized, the CVA-CDT group (75.0%, 15/20) was significantly better than the CFVA-CDT group (34.38%, 11/32), and the difference was statistically significant ( P=0.004). There was no significant difference in clinical efficacy between the two groups ( P=0.819). During follow-up, the femoral-popliteal vein patency rate in the CVA-CDT group (87.50%, 28/32) was significantly higher than in the CFVA-CDT group (44.90%, 22/49), the difference was statistically significant ( P<0.001). Conclusions:Successful CFVA-CDT requires the assistance of more ancillary devices, while the use of larger sheaths is more limited in CVA-CDT due to the smaller caliber of the calf deep veins. The presence or absence of popliteal vein opacification on lower extremity venous antegrade venography may influence the effective thrombolysis of the femoral-popliteal venous segment thrombus in patients with acute mixed deep vein thrombosis (DVT) treated with CFVA-CDT and CVA-CDT. Compared to CFVA-CDT, CVA-CDT can improve the patency rate of the femoral-popliteal venous segment.

OBJECTIVE: To observe the effect of acupuncture at "pelvic floor six needles" for mild to moderate female stress urinary incontinence (SUI). METHODS: A total of 60 patients with mild to moderate female SUI were randomly divided into an observation group and a control group, 30 cases each group. The control group received Kegel exercise. The observation group received acupuncture at "pelvic floor six needles" on the basis of the treatment as the control group, bilateral Zhongliao (BL33), Zhibian (BL54), Huiyang (BL35), Shuidao (ST28), Dahe (KI12) and Guanyuan (CV4) were selected, once every other day, 3 times a week, 4 weeks as a course of treatment, a total of 2 courses were required. Before treatment and after 4, 8 weeks of treatment, urine leakage in 1 hour, International Consultation on Incontinence questionnaire short form (ICI-Q-SF) score, and incontinence quality of life questionnaire (I-QOL) score were observed in the two groups, and the clinical efficacy was evaluated. RESULTS: After 8 weeks of treatment, urine leakage in 1 hour and ICI-Q-SF scores in both groups were decreased compared with those before treatment (P<0.05), and urine leakage in 1 hour and ICI-Q-SF score in the observation group were lower than those in the control group (P<0.05). After 4, 8 weeks of treatment, I-QOL scores were increased compared with those before treatment in both groups (P<0.05), and the I-QOL scores in the observation group were higher than those in the control group (P<0.01, P<0.001). The total effective rate of the observation group was 93.3% (28/30), which was higher than 73.3% (22/30) in the control group (P<0.05). CONCLUSION Acupuncture at "pelvic floor six needles" could improve the clinical symptoms and quality of life in patients with mild to moderate female SUI to a certain degree.

Objective:To evaluate the efficacy and analyze the causes of complications of allogeneic decellularized dermal matrix grafts in the treatment of gingival recession using tunneling technology.Methods:Sixty patients with single or multiple gingival re-cession were randomly divided into an allogeneic decellularized matrix(ADM)group and a connective tissue(SCTG)group.Tunne-ling technique(TUN)were used in both groups to cover the root surface,and the gingival margin position,gingival margin morpholo-gy,and mucogingival junction position of the affected teeth at 1 week,3 weeks,3 months,and 6 months after surgery were observed.Check and record the gingival recession depth(RD)and mean root coverage(MRC)at the implant site before and 6 months after surgery.Record patient satisfaction at 3 weeks and 6 months after surgery.Results:Compared with the traditional SCTG group,the MRC of the ADM group was significantly lower before surgery and 6 months after surgery(P＜0.05).The satisfaction level of the ADM group was higher 3 weeks after surgery,with a significant difference compared to the SCTG group(P＜0.05).But 6 months after surgery,the satisfaction levels of the two groups tended to be consistent,with no significant difference.After TUN+ADM surgery,there was 1 case of abscess infection lesion,and another 3 cases showed local tissue necrosis at the gingival margin one week after surgery.After 3 months of treatment,the gingival color of these 4 patients was pink and tough texture,without swelling and bleeding.Conclusion:Although ADM is slightly inferior to SCTG in the treatment of gingival recession,it may be related to poor postoperative tissue healing complications.However,as long as it is handled properly,long-term follow-up observations have shown that gingival tissue can still achieve complete healing.TUN+ADM is a highly effective treatment for gingival recession and is suitable for further clinical application.

Objective:To evaluate the long-term efficacy of percutaneous microwave ablation (MWA) therapy for hepatocellular carcinoma.Methods:2054 cases with Barcelona Clinic Liver Cancer (BCLC) stage 0~B at the Fifth Medical Center of the Chinese People's Liberation Army General Hospital from January 2006 to September 2020 were retrospectively collected. All patients were followed up for at least 2 years. The primary endpoint of overall survival and secondary endpoints (tumor-related survival, disease-free survival, and postoperative complications) of patients treated with ultrasound-guided percutaneous MWA were analyzed. Kaplan-Meier method was used for stratified survival rate analysis. Fine-and-Gray competing risk model was used to analyze overall survival.Results:A total of 5 503 HCC nodules [mean tumor diameter (2.6±1.6) cm] underwent 3 908 MWAs between January 2006 and September 2020, with a median follow-up time of 45.6 (24.0 -79.2) months.The technical effectiveness rate of 5 375 tumor nodules was 97.5%. The overall survival rates at 5, 10, and 15-years were 61.6%, 38.8%, and 27.0%, respectively. The tumor-specific survival rates were 67.1%, 47.2%, and 37.7%, respectively. The free tumor survival rates were 25.8%, 15.7%, and 9.9%, respectively. The incidence rate of severe complications was 2.8% (108/3 908). Further analysis showed that the technical effectiveness and survival rate over the passing three time periods from January 2006-2010, 2011-2015, and 2016-September 2020 were significantly increased, with P ?

Purpose To investigate the feasibility of apoptosis small-molecule probe CYS-F for in vivo molecular imaging in acute middle cerebral artery embolization and recalculation models,and to explore its ability to reflect lesions.Materials and Methods Hela cell apoptosis was induced by Adriamycin,and the targeting ability of the probe was verified in vitro.Clinical middle cerebral artery embolization was simulated,acute ischemic stroke model(n=15)and recanalization model(n=15)were constructed,and the vessels were evaluated by magnetic resonance angiography imaging.The distribution of CYS-F was investigated by injecting the probe into the caudal vein.24 hours after modeling,the lesion volume rate was assessed on T2WI,and apoptosis was assessed in vivo by near infrared imaging.Niss and c-fos staining were used to compare the differences between the two groups.Results CYS-F showed a good ability to target apoptosis in vitro.After modeling,Doppler flowmeter and magnetic resonance angiography showed that the middle cerebral artery was successfully embolized in the embolization group,and the artery was recanalized in the recanalization group.Near infrared imaging showed the loss of fluorescence signal in the middle cerebral artery region in the embolized group.24 hours after modeling,T2WI showed that the infarct volume rate in the recanalization group was significantly lower than that in the embolization group(0.055±0.015 vs.0.512±0.220;t=19.761,P<0.001).The fluorescence intensity of the embolization group was significantly stronger than that of the recusing group,the target to background ratio was 1.215±0.162 and 0.731±0.085,respectively(t=10.252,P<0.001).In the embolization group,a large number of activated neurons expressed c-fos protein,and a large number of cells underwent nuclear condensation and lysis by Niss staining.Conclusion The acute embolization model and recalculation model of middle cerebral artery in mice are close to the clinic.CYS-F can be used to image apoptosis in vivo,reflect the lesion degree,and reflect the local tissue blood perfusion at the initial stage of injection.

In various immunomodulatory systems,there exists a transmembrane receptor expressed on the surface of immune cells,which can play a role selectively,namely the sialic-binding immunoglobulin-like lectin(Siglec)family.Inhibition of host T cell antigen response is a key factor in inducing immune tolerance of liver transplantation.Recently,Siglec-15 has been found to be an important T cell suppressor molecule,and some of its family members have similar structure and biological characteristics.It is speculated that the mem-bers of Siglec family may be a new target for inducing liver immune tolerance.Therefore,this paper reviews the relevant literatures in this field,and takes Siglec-15 as the entry point to explore the possible role and mo-lecular mechanism of Siglec family in inhibiting host T cell antigen response and regulating immune response in order to provide the new ideas for the establishment of immune regulation and tolerance after transplanta-tion.
