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 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 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.

Compared to CFVA-CDT, CVA-CDT can improve the patency rate of the femoral-popliteal venous segment.

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.

Ferroptosis,a programmed cell death induced by iron-dependent lipid peroxidation and excessive accumulation of reactive oxygen species,is a key pathological mechanism of neuronal death during the progression of Alzheimer's disease(AD),contributing to the formation of"Ferroptosis Hypothesis"for AD pathogenesis.In recent years,there has been extensive research on therapeutic strategies for AD based on the pathogenic mechanism of ferroptosis,focusing primarily on the dysregulation of brain iron metabolism and redox regulation in microenvironment.However,presence of blood-brain barrier and intricate pathological environment within brain impose limitations on intracranial drug transportation,distribution and therapeutic efficacy,thereby necessitating advancements in drug delivery technology.Based on description of ferroptosis process and its regulatory mechanisms,this review explores the association between iron overload and redox imbalance with neuronal loss and AD development,and additionally,summarizes the advancements in nano drug delivery systems targeting iron overload and redox imbalance for potential anti-AD treatments,so as to offer some novel perspectives for AD treatment and drug development.

ObjectiveTo adapt the Stanford Expectations of Treatment Scale（SETS） into Chinese（C-SETS） and test the feasibility， validity and reliability of its application in patients with diarrhea-predominant irritable bowel syndrome（IBS-D） with liver-constraint and spleen-deficiency syndrome treated with traditional Chinese medicine（TCM）. MethodsWe obtained authorisation from the developer of the SETS， and followed the principle of "two-way translation" to translate the SETS by literal translation and back translation to form the C-SETS. Ninety-six IBS-D patients with liver-constraint and spleen-deficiency syndrome were enrolled as respondents and filled out C-SETS before receiving treatment； the feasibility was assessed by the recall rate， completion rate and the duration of filling out the scale； the reliability was assessed by Cronbach's α； the structural validity was assessed by exploratory and confirmatory factor analysis， and the content validity was assessed by correlation analysis. ResultsThe C-SETS consists of 10 items， with the 1st， 3rd， and 5th rating items constituting the Positive Expectations subscale， and the 2nd， 4th， and 6th rating items constituting the Negative Expectations subscale， each of which is rated on a 7-point Likert Scale. The recall of C-SETS was 100%（96/96）， the completion rate was 89.58%（86/96）； Cronbach's α for the Positive and Negative Treatment Expectations subscales were 0.845 and 0.854， respectively； exploratory factor analysis showed that the coefficient of commonality for all six entries was larger than 0.4， and that the six entries could be used by both factors to explain 77.092% of the total variance； validation factor analysis showed that the goodness-of-fit index， comparative fit index， root mean square of approximation error， canonical fit coefficient， and chi-square degrees of freedom ratio took the values of 0.943， 1.003， 0， 0.943， and 0.626， respectively； and the results of Spearman's analysis suggested that the C-SETS had good content validity. ConclusionThe C-SETS has well feasibility， reliability， and validity， which initially proves that it can be used as a tool to assess the treatment expectation of patients with IBS-D with liver-constraint and spleen-deficiency syndrome before receiving TCM treatment.

Objective:To investigate the perioperative impact of closure of mesenteric fissure in laparoscopic right hemicolectomy.Methods:The prospective randomized controlled trial was conducted. The clinical data of 320 patients who underwent laparoscopic right hemicolectomy in 11 medical centers, including The First Affiliated Hospital of China Medical University et al, from November 2022 to August 2023 were selected. Based on block randomization, patients were alloca-ted into the mesenteric fissure non-closure group and the mesenteric fissure closure group. Observa-tion indicators: (1) grouping of the enrolled patients; (2) intraoperative conditions; (3) postopera-tive conditions. Measurement data with skewed distribution were represented as M( Q1, Q3) and com-parison between groups was conducted using the Mann-Whitney U test. Count data were represen-ted as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher's exact probability. Comparison of ordinal data was conducted using the rank sum test. Comparison of visual analog scores was analyzed using generalized estimating equations. Results:(1) Grouping of the enrolled patients. A total of 320 patients with colon cancer were screened for eligibility, including 156 males and 164 females, aged 68(59,73)years. All the 320 patients were allocated into the mesenteric fissure non-closure group with 164 cases and the mesenteric fissure closure group with 156 cases. There was no significant difference in the age, body mass index, American Society of Anesthesiologist score, maximum tumor diameter, anastomosis location, anastomosis method, surgical approach, range of lymph node dissection, tumor staging between the two groups ( P>0.05) and there was a significant difference in the sex between them ( P<0.05). (2) Intraoperative conditions. There was no significant difference between the mesenteric fissure closure group and the mesenteric fissure non-closure group in the volume of intraoperative blood loss, operation time, conversion to laparotomy, intraoperative complication ( P>0.05). Three patients in the mesenteric fissure non-closure group were converted to laparotomy. One patient in the mesenteric fissure closure group was converted to laparotomy, and 2 cases with intraoperative complication were mesenteric hematoma. (3) Postoperative conditions. There was no significant difference between the mesenteric fissure non-closure group and the mesenteric fissure closure group in the overall postoperative complications ( χ2=0.28, P>0.05). There was no significant difference in the occurrence of postoperative intestinal obstruction, abdominal distension, ascites, pleural effusion, gastric paralysis, anastomotic bleeding, anastomotic leakage, or surgical wound infection between the two groups ( P>0.05). There was no significant difference between the two groups in the reoperation, postoperative gastric tube replacement. There was no significant differ-ence in time to postoperative first flatus, time to postoperative initial liquid food intake, time to post-operative resumption of bowel movements, duration of postoperative hospital stay, total hospital expenses between the two groups ( Z=-0.01, 0.43, 1.04, -0.54, -0.36, P>0.05). One patient in the mesenteric fissure non-closure group received reoperation. No perioperative internal hernia or death occurred in either group. The visual analog score decreased with time in both groups. There was no significant difference in the visual analog score between the mesenteric fissure closure group and the mesenteric fissure non-closure group [ β=-0.20(-0.53,0.13), P>0.05]. Conclusion:Compared with closure of mesenteric fissure, non-closure of mesenteric fissure during laparoscopic right hemi-colectomy dose not increase perioperative complications or postoperative management risk.
