The rapid development of artificial intelligence (AI), especially generative AI (GenAI), has already brought, and will continue to bring, revolutionary changes to our daily production and life, as well as create new opportunities and challenges for diagnostic and therapeutic practices in the medical field. Haihe Hospital of Tianjin University collaborates with the National Supercomputer Center in Tianjin, Tianjin University, and other institutions to carry out research in areas such as smart healthcare, smart services, and smart management. We have conducted research and development of a full-process disease diagnosis and treatment assistance system based on GenAI in the field of smart healthcare. The development of this project is of great significance. The first goal is to upgrade and transform the hospital's information center, organically integrate it with existing information systems, and provide the necessary computing power storage support for intelligent services within the hospital. We have implemented the localized deployment of three models: Tianhe "Tianyuan", WiNGPT, and DeepSeek. The second is to create a digital avatar of the chief physician/chief physician's voice and image by integrating multimodal intelligent interaction technology. With generative intelligence as the core, this solution provides patients with a visual medical interaction solution. The third is to achieve deep adaptation between generative intelligence and the entire process of patient medical treatment. In this project, we have developed assistant tools such as intelligent inquiry, intelligent diagnosis and recognition, intelligent treatment plan generation, and intelligent assisted medical record generation to improve the safety, quality, and efficiency of the diagnosis and treatment process. This study introduces the content of a full-process disease diagnosis and treatment assistance system, aiming to provide references and insights for the digital transformation of the healthcare industry.

Immune checkpoint inhibitors (ICIs) are currently used in the treatment of various tumors and play an important role in tumor treatment, resulting in many adverse reactions related to the immune system. Type 1 diabetes (T1DM) is a rare endocrine system complication, which is rarely reported at present. We report a case of T1DM after using ICIs to treat gastric cancer. The patient was a 34 year old male who developed diabetes ketoacidosis after 206 days of sintilimab monoclonal antibody use, with fasting blood glucose of 15.78 mmol/L and glycosylated hemoglobin of 8.6%. Islet related antibody: Glutamate decarboxylase antibody: 119.2 IU/mL; Insulin antibody:<2 IU/L. Fasting insulin: 0.21 mU/L; Fasting C-peptide: 0.12 μg/L. Through the analysis of patients' clinical data, it aims to improve clinicians' understanding of immune related type 1 diabetes and provide ideas for correct diagnosis and treatment.

ObjectiveTo evaluate the efficacy and clinical safety of sodium glycididazole (CMNa)in thoracic esophageal squamous carcinoma.Methods From June 1,2008 to October 13,2009,66pathologically proved thoracic esophageal squamous carcinoma (stage Ⅱa-Ⅲ,stage Ⅳ with metastases only in supraclavicular lymph nodes,by AJCC 6th ed) were randomized into radiotherapy plus CMNa (A) or radiotherapy plus placebo (B) group.Radiotherapy was given by conventional schedule:1.8-2.0 Gy per fraction,5 times per week to a total dose of 66 Gy/6.6-7.2w.CMNa was given intravenously 800 mg/m2 3 times a week in solution of 100 ml saline within 30 minutes.Radiotherapy was started 30-60 minutes after completion of infusion.Patients of Group B received placebo in saline solution.A total of 66 patients were enrolled ( Group A:32 ; Group B:34 ),and four patients were unanalyzable,remaining 31 patients in each Group.Baseline factors were balanced.ResultsFollow-up rate was 97％.Group A vs.Group B:the overall response rate was 93.5％ vs.67.7％ ( x2 =6.61,P =0.01 ),2-year overall survival was 39.9％ vs.29.9％ ( x2 =0.62,P =0.433 ),2-year cancer specific survival was 43.1％ vs.26.8％ ( x2 =0.30,P =0.878),and 2-year progression-free survival was 30.1％ vs.27.9％ ( x2 =0.02,P =0.586).No severe side effects observed.All patients tolerated CMNa infusion well.Conclusions CMNa is tolerable and effective as a hypoxic radiosensitizer,and its combination with radiotherapy can improve short term effect.However,survival is not improved within our follow-up period.

Objective To evaluate the long-term clinical efficacy and toxicities of combined intracavitary hyperthermia and radiotherapy fur locally advanced uterine cervical cancer. Methods 310 patients with locally advanced uterine cervical cancer were assigned into intracavitary hyperthermia + radiotherapy group(TRT, 181 patients) and external-beam radiotherapy + traditional intracavitary radiation group (RT,129 patients). The external-beam radiotherapy were given with 60Co γ-my or 6-8 MV X-ray in traditional fractionation. In TRT group,radiotherapy was 40 Gy using the anterior-posterior pelvic fields and additional 20-25 Gy using the lateral fields. Hyperthermia was delivered by the 915 MHz microwave hyperthermia device within 15-60 min after external radiotherapy for 10-12 times(40 min each time,1-2 times per week). The temperature of tumor surface was 46-47℃. In the RT group, the external-beam radiotherapy of 40 Gy was delivered using the anterior-posterior pelvic fields. The intracavity radiotherapy of radium was delivered before 1989 ,with 50 mg radium in the vagina and 30 mg in uterine cavity for 24 hours ,weekly for 3 times to a total dose of 7200 mg·h. After 1989,intraeavity radiotherapy of 192Ir was delivered to a total dose of 30-36 Gy to point A in 5-6 Gy fractions,2 fractions per week. Results The 5-year survival of patients in TRT group and RT group was 67.4% versus 52.1% for stage Ⅱ disease (χ2=7.55,P=0.006), and 60.0% vemus32.3% forstage Ⅲ (χ2=7.06,P=0.007) . The 10-year survival was46.5% versus42.6% for stage Ⅱ (χ2=3.90,P=0.058), and 43.7% versus 20.6% for stage Ⅲ(χ2=17.28,P=0.000). Cox regression analysis showed that the tumor stage(P=0.023) and intracavitary hyperthermia( P=0.019) were prognostic factors. According to the RTOG criteria, the rate of mild to moderate late side effects of rectum and bladder in TRT and RT group was 17.7% and 33.1%, respectively (χ2=9.18, P=0.002). Rectovaginal fistula was developed in5 patients(3.9% ) in RT group and I patient (0.6%) in TRT group(χ2= 4.38,P=0.036). Conclusions The long-term survival of patients with stage Ⅲ uterine cervical cancer is better of TRT group than RT group. The TRT is well tolerated and the late toxicity rate is obviously low. It is necessary to carry out large randomized clinical trials to confirm these outcomes.

A simple spcctrophotometric method for determination of total rare-earth metals in food is presented. Weigh 5 gm of dry sample in a dish. After soaking the sample more than half an hour with 10 ml 3N H2SO4, evaporate to dryness on a hot plate and ash at 600℃. Dissolve the ash in 1 ml 6N HCl, and evaporate to dryness.

The sensitivity of the method is 0.01 ?g/ml and the detection limit is 0.05ppm (5 gm of sample). The average recovery of added TRExOy is 91.9% (n = 14).

Objective: To study the amount of fat, cholesterol and fatty acid intake in China and provide the basic material for dietary guidance. Methods: Two areas were selected both in North and South China and each area included 3 provinces, or municipality or autonomous region. Three representative survey sites were selected in each province, or municipality or autonomous region. Dietary survey was conducted by the method of weighing and recording and cooking method was also recorded. The amount of food consumption was calculated as standard person (adult male, light physical activity). All foods were gathered as 12 kinds of foods, and each kind of food was cooked and then mixed. The content of fat and fatty acid was analyzed for 8 kinds of foods and the content of cholesterol was analyzed for 4 kinds of foods. The intake of fat, fatty acid and cholesterol per capita was calculated. Results: The amount of fat intake among North I, North II, South I, South II was 70.5 g, 46.5 g, 58.7 g, 71.0 g respectively and the amount of cholesterol intake was 329.6 mg, 128.5 mg, 400.9 mg, 306.0 mg respectively. The main source of dietary fat was from meat and vegetables. Egg was the main source of dietary cholesterol and meat and egg were both the main source of dietary cholesterol in south II area. About 90% of saturated fatty acid was palmitic acid and stearic acid and 90% of monounsaturated fatty acid was oleic acid. Linoleic acid was the principal n-6 polyunsaturated fatty acid and linolenic acid was the principal n-3 polyunsaturated fatty acid. The ratio of S∶M∶P in North I was 1∶1.1∶1, in North II was 1∶1.6∶1.3, in South I was 1∶1.6∶1.3 and in South II was 1∶1.5∶1. Conclusion: The amount of fat intake and fatty acid profile was quite different among different areas and the dietary guidance should be more pertinent The current cholesterol intake was more than dietary guidance in most areas. In addition to egg, meat was also an important source of cholesterol.
