This study evaluates the clinical efficacy and safety benefits of immunotherapy in a selected patient population by comparing serplulimab combined with short-course SOX regimen versus SOX regimen alone as adjuvant therapy for patients with stage pII-III gastric or gastroesophageal junction (G/EGJ) adenocarcinoma who are PD-L1 CPS ≥5, EBV-positive, or dMMR/MSI-H.

This study will evaluate the effectiveness and safety of HRS-4642 in combination with nab-paclitaxel and gemcitabine (AG regimen) as conversion therapy for patients with locally advanced pancreatic cancer. Participants will undergo regular assessments, including imaging scans and CA19-9 biomarker tests. If disease recurrence is suspected, unscheduled evaluations may be performed. For participants who discontinue treatment due to reasons other than disease progression (e.g., toxicity), tumor assessments will continue as scheduled until progression, loss to follow-up, death, consent withdrawal, or study termination. After the final treatment, participants will enter a survival follow-up phase. Investigators will contact the participants or their families approximately every month (±7 days) to collect information on survival status (date and cause of death) and any subsequent anti-cancer treatments until death, loss to follow-up, study termination, or other study endpoints are met. All follow-up information will be documented in the medical records.

The primary efficacy endpoint is objective response rate (ORR).

\*\*Research Background\*\* Colostomy surgery is a common surgical procedure widely used for the treatment of various gastrointestinal diseases, including rectal cancer, ulcerative colitis, and Crohn's disease. Although this surgery can significantly improve patients' quality of life and prognosis, the incidence of postoperative complications, particularly parastomal hernia (PSH), is relatively high. PSH refers to the formation of an abdominal wall hernia around the stoma, with an incidence rate that can reach up to 50%. PSH not only affects patients' quality of life but can also lead to pain, stoma dysfunction, and the need for reoperation, increasing medical costs and patient burden. Therefore, how to effectively prevent PSH has become an important topic in clinical research. \*\*Epidemiology of Parastomal Hernia\*\* The incidence of PSH varies across different studies, ranging from 10% to 50%. This variation may be due to differences in study design, patient characteristics, and surgical techniques. A systematic review and meta-analysis showed that the incidence of PSH differs significantly among different surgical techniques, with higher rates observed in traditional non-molding suturing techniques. Another large cohort study found that the incidence of PSH varies among different age groups and patients with different underlying diseases, suggesting that PSH occurrence may be influenced by multiple factors. \*\*Risk Factors for Parastomal Hernia\*\* 1. \*\*Patient Factors\*\*: * \*\*Advanced Age\*\*: Older patients have reduced tissue elasticity and muscle strength, making them more susceptible to PSH. * \*\*Obesity\*\*: Obese patients have higher intra-abdominal pressure, increasing the risk of PSH. * \*\*Smoking\*\*: Smoking impairs wound healing, increasing the risk of PSH. * \*\*Chronic Obstructive Pulmonary Disease (COPD)\*\*: COPD patients often experience coughing and breathing difficulties, leading to increased intra-abdominal pressure and a higher risk of PSH. * \*\*Diabetes\*\*: Diabetic patients have poorer wound healing capabilities, making them more prone to PSH. * \*\*Malnutrition\*\*: Malnutrition impairs tissue repair, increasing the risk of PSH. 2. \*\*Surgical Factors\*\*: * \*\*Surgical Technique\*\*: Different surgical techniques have a significant impact on the incidence of PSH. Traditional non-molding suturing techniques, which lack support for the tissues around the stoma, have a higher incidence of PSH. * \*\*Stoma Location\*\*: Improper stoma placement, such as outside the rectus abdominis muscle, increases the risk of PSH. * \*\*Stoma Size\*\*: An oversized or undersized stoma can affect stoma function and increase the risk of PSH. * \*\*Use of Mesh\*\*: Using synthetic or biological mesh can significantly reduce the incidence of PSH. However, the use of mesh may bring risks of infection and other complications. 3. \*\*Postoperative Factors\*\*: * \*\*Early Mobilization\*\*: Appropriate early mobilization promotes circulation and wound healing, but excessive activity can increase intra-abdominal pressure and the risk of PSH. * \*\*Increased Intra-abdominal Pressure\*\*: Activities such as coughing, constipation, and heavy lifting can increase intra-abdominal pressure and the risk of PSH. * \*\*Infection\*\*: Postoperative infections can impair wound healing and increase the risk of PSH. \*\*Prevention Strategies for Parastomal Hernia\*\* 1. \*\*Improvement in Surgical Techniques\*\*: * \*\*Mesenteric Molding Suturing\*\*: In recent years, mesenteric molding suturing has gained attention due to its potential advantages. Mesenteric molding suturing strengthens the support around the stoma, reducing the protrusion of abdominal contents and thus lowering the incidence of PSH. A retrospective study showed that patients who underwent mesenteric molding suturing had a significantly lower incidence of PSH compared to those who received traditional non-molding suturing. However, these studies are mostly retrospective and have certain biases and limitations, lacking high-quality prospective randomized controlled trials to validate these findings. * \*\*Use of Mesh\*\*: Some studies have shown that using synthetic or biological mesh can significantly reduce the incidence of PSH. The mesh provides additional support, reducing the protrusion of abdominal contents and thus lowering the risk of PSH. However, the use of mesh may bring risks of infection and other complications, requiring a careful balance of benefits and risks. 2. \*\*Postoperative Care\*\*: * \*\*Early Mobilization Guidance\*\*: Appropriate early mobilization promotes circulation and wound healing, but excessive activity should be avoided to prevent increased intra-abdominal pressure. * \*\*Avoidance of Increased Intra-abdominal Pressure\*\*: Patients should be advised to avoid activities that can increase intra-abdominal pressure, such as coughing, constipation, and heavy lifting. * \*\*Infection Prevention\*\*: Keeping the stoma area clean and dry and promptly managi

Metastatic colorectal cancer with microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) molecular phenotypes could significantly benefit from immune checkpoint inhibitor therapy, ushering in the MSI era of immunotherapy for colorectal cancer. However, MSI-H/dMMR is present in only 15%-20% of stage II/III and 5% of stage IV colorectal cancer patients, while the vast majority of patients exhibit microsatellite stability (MSS) or proficient mismatch repair (pMMR) types, which are insensitive to immunotherapy. Therefore, how to enhance the efficacy of immunotherapy in the pMMR/MSS population through combination therapy has become a hotspot and challenge in colorectal cancer research.

This is a prospective, single-center, randomized controlled phase II clinical trial.It plans to enroll a total of 24 eligible patients with locally advanced gastric/gastroesophageal junction adenocarcinoma who are HER2-positive and have potential benefit from immunotherapy (PD-L1 CPS≥1, EBV-positive, or dMMR/MSI-H). All patients were randomly assigned to the following two groups in a 1:1 ratio. Group A:Trastuzumab Rezatecan Dosage: 4.8 mg/kg, intravenous infusion Frequency: Once every 3 weeks (Q3W) Retlirafusp alfa (SHR-1701) Dosage: 30 mg/kg, intravenous infusion Frequency: Once every 3 weeks (Q3W) Group B: Trastuzumab Rezatecan Dosage: 4.8 mg/kg, intravenous infusion Frequency: Once every 3 weeks (Q3W) Retlirafusp alfa (SHR-1701) Dosage: 30 mg/kg, intravenous infusion Frequency: Once every 3 weeks (Q3W) Pertuzumab biosimilar (Betta Pharma): 840mg at first usage; subsequent maintenance: 420mg per dose,Q3W The neoadjuvant treatment phase will consist of 4 cycles, with each cycle lasting 21 days, for a total treatment duration of approximately 12 weeks. Imaging examinations will be performed after 2 cycles. Preoperative Assessment and Surgery Within 4 weeks after the completion of neoadjuvant therapy, patients will undergo imaging examinations for surgical feasibility assessment. Those eligible for surgery will undergo radical gastrectomy (D2 lymphadenectomy) 4-6 weeks after the last dose.

This study aims to investigate the thrombolytic efficacy of platelet membrane-coated tenecteplase (PM-TNK) on human ex vivo arterial thrombi, and to explore the inhibitory effects of plasma from patients receiving antiplatelet therapy on its thrombolytic activity, thereby evaluating the future clinical application value of PM-TNK.

Purpose Hepatic encephalopathy (HE) is a serious complication of liver cirrhosis that can cause memory loss, slow reaction, and even coma. In China, large-scale epidemiological data on HE are lacking, early diagnosis remains difficult, and treatment needs improvement. This study aims to investigate the prevalence of HE in Chinese liver disease patients and to explore better diagnostic methods and treatment strategies. Design This is a prospective, multicenter cohort study led by Jiangsu Province Hospital, in collaboration with 7 other hospitals in Jiangsu Province. Between April 2026 and December 2029, the study plans to enroll over 700 patients with liver cirrhosis and 120 healthy volunteers. What participants will do Participants will use a WeChat mini-program to perform simple cognitive tests (e.g., reaction speed, attention) regularly. They will be followed up at month 1, 3, 6 after enrollment, and then every six months. The research team will collect routine laboratory results, medication records, and quality-of-life data. Benefits and risks Participants will receive closer health monitoring, which may help detect changes early. The study involves no additional drugs or invasive procedures, so risks are very low. All personal information will be kept strictly confidential and used only for medical research. Voluntary participation Participation is completely voluntary, and participants can withdraw at any time without affecting their routine medical care.

With high incidence and mortality rate, the effective therapeutic options of colorectal cancer remain limited. Up to 50% of patients with colorectal cancer will develop metastatic disease. Recurrent lesions can be diagnosed and characterized only when tumors have reached a certain volume by present radiologic imaging techniques such as CT and MRI. The exploration of differentiated clinical applications specifically for local recurrence versus distant metastasis remains an unmet need. The aim of this study is to explore methylation, fragmentomic, and cfRNA markers associated with local recurrence and distant metastasis of colorectal cancer by multi-omics approaches. By constructing a predictive model for the localization of post-treatment recurrence and metastasis, this study will compare the accuracy of different technical approaches in predicting the localization of recurrence and metastasis after colorectal cancer treatment.

The objective of this observational study is to evaluate the oncological safety of breast-conserving surgery combined with standard postoperative radiotherapy in adult female patients diagnosed with multifocal or multicentric breast cancer. The main questions it aims to answer are: What is the local recurrence rate and the time distribution of local recurrence after breast-conserving therapy in patients with multifocal or multicentric breast cancer? What independent risk factors are associated with postoperative local recurrence among these patients? There is no separate comparison group in this single-arm prospective cohort study. Participants will: Receive standardized breast-conserving surgery plus routine postoperative radiotherapy and individualized adjuvant therapy in accordance with clinical guidelines; Complete regular clinical follow-up visits, telephone and WeChat follow-ups for at least 3 years after surgery to collect data on surgical complications, tumor recurrence, metastasis and survival status; Fill out standardized questionnaires including Breast-Q, SDS, SAS and EORTC QLQ-C30 to assess postoperative breast satisfaction, psychological status and quality of life.

Brief Summary Purpose: This is a proof-of-concept clinical trial to evaluate whether Dihydroartemisinin (DHA), a medication commonly used to treat malaria, can effectively reduce liver fat in adults with Metabolic Associated Fatty Liver Disease (MAFLD). The study will also rigorously assess the safety and tolerability of DHA in this specific patient population. Study Design: This is a single-center, open-label, single-arm study. All qualified participants will receive the investigational treatment, with each individual serving as their own baseline control to measure pre- and post-treatment changes. To minimize lifestyle-related confounding factors, all participants will receive standardized dietary and physical activity counseling at baseline and will be instructed to strictly maintain their established lifestyle routines throughout the study period. Participants: The study plans to enroll approximately 30 adult patients (ages 18 to 45 years) formally diagnosed with MAFLD. MAFLD is defined by the presence of excessive hepatic fat accumulation concurrent with specific metabolic dysfunctions, such as overweight/obesity, hypertension, elevated blood sugar, or dyslipidemia. Intervention: Participants will be administered oral Dihydroartemisinin tablets at a dose of 20 mg three times daily (TID) for a continuous duration of 12 weeks. Upon completion of the intervention, participants will enter a 12-week observational follow-up period to monitor the durability of the treatment effects and long-term safety. Main Things We Will Measure (Outcomes): Primary Outcome: Absolute change in liver fat content from baseline to the end of the 12-week treatment, quantitatively assessed by the gold-standard MRI Proton Density Fat Fraction (MRI-PDFF). Secondary Outcomes: Changes in supplementary non-invasive liver fat assessments (including Ultrasound-derived Fat Fraction \[UDFF\] and FibroScan Controlled Attenuation Parameter \[CAP\]), as well as changes in body weight, blood pressure, heart rate, and routine laboratory safety panels (e.g., comprehensive liver and kidney function tests).

To explore the efficacy and safety of sintilimab combined with ramucirumab and paclitaxel in the treatment of advanced gastric cancer patients with short-term recurrence after postoperative adjuvant therapy, and to identify efficacy-related biomarkers to guide subsequent individualized treatment.

The goal of this observational study is to analyze clinicopathological characteristics and identify independent prognostic risk factors, as well as compare treatment outcomes in female patients aged ≥18 years with pathologically confirmed local recurrence of breast cancer after radical surgery (breast-conserving surgery or total mastectomy) without distant metastasis. The main questions it aims to answer are: What clinical and pathological factors independently affect progression-free survival (PFS) and overall survival (OS) of breast cancer patients with postoperative local recurrence? Do clinical features and long-term prognosis differ between patients with local recurrence after breast-conserving surgery and those after total mastectomy? Can we identify optimal individualized treatment regimens and suitable populations for re-breast-conserving surgery and postoperative radiotherapy after R0 resection? Participants will: Provide complete baseline demographic, initial clinicopathological, primary surgical and adjuvant treatment data, local recurrence lesion characteristics and post-recurrence treatment information via standardized case report forms; Undergo routine clinical examinations, imaging reviews and pathological rechecks as standard clinical practice; Receive standardized follow-up for at least 3 years through outpatient visits supplemented by telephone/WeChat contact to record disease progression, secondary local recurrence, distant metastasis, all-cause death and treatment adverse events.

The purpose of this clinical trial is to evaluate the safety and effectiveness of a new combination therapy for patients with biliary tract cancer that cannot be removed by surgery. Participants will receive an immunotherapy drug called adebrelimab combined with two chemotherapy drugs (gemcitabine and albumin-bound paclitaxel) as their first-line treatment. This is an open-label, single-arm study, meaning all enrolled patients will receive this same combination treatment. The main goal of the study is to determine the Objective Response Rate (ORR), which measures the proportion of patients whose tumors shrink in response to the treatment. Researchers will also evaluate how long patients live without the disease getting worse (Progression-Free Survival), overall survival, quality of life, and any side effects experienced. The study plans to enroll 30 participants.
