Acute liver injury (ALI) serves as a critical precursor and major etiological factor in the progression and ultimate manifestation of various hepatic disorders. The prevention and treatment of ALI is still a serious global challenge. Given the limited therapeutic options for ALI, exploring novel targeted therapeutic agents becomes imperative. The potential therapeutic efficacy of inhibiting RIPK2 is highlighted, as it may provide significant benefits by attenuating the MAPK pathway and NF-κB signaling. Herein, we propose a CMD-OPT model, a two-stage molecular optimization tool for the rapid discovery of RIPK2 inhibitors with optimal properties. Compound RP20, which targets the ATP binding site, demonstrated excellent kinase specificity, ideal oral pharmacokinetics, and superior therapeutic effects in a model of APAP-induced ALI, positioning RP20 as a promising preclinical candidate. This marks the first application of RIPK2 inhibitors in ALI treatment, opening a novel therapeutic pathway for clinical applications. These results highlight the efficacy of the CMD-OPT model in producing lead compounds from known active molecules, showcasing its significant potential in drug discovery.

Using big data and artificial intelligence to establish a multi-point monitoring, early warning, and disposal system to achieve early warning and intervention of infectious disease outbreaks is an important means of controlling the spread of the epidemic. Taking Xiaoshan district as an example, this study analyzes the monitoring contents, warning methods, and application effectiveness of the infectious disease monitoring, early warning and disposal system. Based on Xiaoshan′s health big data resources, the system starts with syndrome, disease diagnosis and etiology. Through advanced technologies such as artificial intelligence and block chain, it realizes early identification of infectious disease outbreaks, data fusion, multi-cross collaboration, and closed-loop management. It has improved the sensitivity of clustered outbreaks monitoring and the effectiveness of epidemic disposal and provided a reference for grassroots disease prevention and control departments to establish an infectious disease monitoring and early warning system.

Objective: To evaluate the efficacy and safety of ultrafiltration in patients with heart failure. Methods: One hundred and thirty four cases of patients with heart failure, who hospitalized in our hospital from June 2010 to June 2016 were enrolled in this study. Random serial number was generated using SPSS 22.0 software, patients were then randomly divided into control group and ultrafiltration group with the proportion of 1∶1 (67 cases in each group). Patients in the control group received standard therapy. Patients in the ultrafiltration group received ultrafiltration therapy for 8 hours. Curative effect was evaluated after 8 hours treatment in the control group and after 12 hours in the ultrafiltration group. Following parameters were compared between the two groups: body weight, dyspnea score and 6 minutes walking distance as well as blood pressure, heart rate, Na⁺ , K⁺ , Cl^-, pH, HCO₃^-, Hb, PLT, Cr, BUN levels. Results: (1)Two patients died during run-in process and eventually 132 cases were chosen for final analysis (65 cases in control group and 67 cases in the ultrafiltration group). Gender, age, type of heart failure, dyspnea score, body weight at baseline were similar between the two groups. (2)Post therapy, patients′ body weight decreased obviously, while dyspnea score and 6 minutes walking distance increased significantly in the ultrafiltration group compared to baseline(all P<0.05), and the improvement was significantly greater compared to control group(all P<0.05). (3)The safety index comparison of two groups: blood pressure, heart rate, Na⁺ , K⁺ , Cl^-, pH, HCO₃^-, Hb, PLT, Cr, and BUN were similar between the two groups at baseline and post therapy. Conclusion Ultrafiltration therapy is safe and effective to treat patients with heart failure.

OBJECTIVETo explore the clinical diagnostic features and treatment of desmoplastic small round cell tumor (DSRCT), and to improve the understanding and management of this tumor.

METHODSThe clinicopathological data of nine patients treated in our hospital from October 2004 to June 2014 were retrospectively analyzed and a review of the literature was made. The clinical manifestations, pathological characteristics, diagnosis and differential diagnosis, treatment and prognosis of this tumor were summarized and analyzed.

RESULTSNine patients with DSRCT, 5 males and 4 females, with an average age of 21 years (range 8-56 years) were included in this study. Ultrasound examination revealed irregular low-density mass shadow in the abdominal cavity. CT examination found that 6 cases had abdominal and retroperitoneal multiple solid tumor nodules, uneven density, and visible low density fluid area. Postoperative pathological examination revealed that the tumor cells were small, mostly elliptic, gathered to form clear structure of nests with clear irregular boundaries. The central portion of large tumor nests often showed necrosis. Scattered fibroblasts and large amount of hyalinization of collagen fibers were seen in the interstitial tissue around the nests. Six patients received laparotomy surgery, however, all failed to resect the tumor completely. Three patients received postoperative chemotherapy, i. e. two cases had carboplatin and paclitaxel chemotherapy, and one case of chemotherapy regimen not specified. Two patients had radiation and chemotherapy (no concrete plan was available). Another case was lost to follow-up. Two of the three patients without surgery received chemotherapy with CAP (cyclophosphamide+adriamycin+carboplatin) and total rectal lesions, pelvic and inguinal lymph nodes, ilium metastases radiation therapy. Another one patient received EP regimen (DDP+VP16) which was then changed into a TP chemotherapy alone. Eight of the nine cases died shortly after surgery, and only one patient treated with chemotherapy alone was still alive after 11 months of follow-up.

CONCLUSIONSDesmoplastic small round cell tumor is a very rare, special type of soft tissue tumor, with very poor prognosis. This tumor may be preliminarily diagnosed according to the imaging characteristics and detection of tumor markers, however, final diagnosis is made by pathology. Surgery is the priority of treatment, combined with complementary radiation and chemotherapy.
