PURPOSE: Prompt vascular access is crucial for resuscitating bleeding trauma casualties in prehospital settings but achieving peripheral intravenous (PIV) access can be challenging during hemorrhagic shock due to peripheral vessel collapse. Early intraosseous (IO) device use is suggested as an alternative. This study examines injury characteristics and factors linked to IO access requirements. METHODS: A registry-based cohort study from the Israel Defense Forces Trauma Registry (2010 - 2023) included trauma casualties receiving PIV or IO access prehospital. Casualties who had at least one documented PIV or IO access attempt were included, while those without vascular access were excluded. Casualties requiring both PIV and IO were classified in the IO group. Univariable logistic regression assessed the factors associated with IO access. Results were reported as odds ratios (OR) with 95% confidence intervals (CI), and significant difference was set at p < 0.05. RESULTS: Of 3462 casualties (86.3% male, the median age: 22 years), 3287 (94.9%) received PIV access and 175 (5.1%) had IO access attempts. In the IO group, 30.3% received freeze-dried plasma and 23.4% received low titer group O whole blood, significantly higher than that in the PIV group. Prehospital mortality was 35.0% in the IO group. Univariable analysis showed significant associations with IO access for increased PIV attempts (OR = 1.69; 95% CI: 1.34 - 2.13) and signs of profound shock (OR = 11.0; 95% CI: 5.5 - 23.3). CONCLUSION Profound shock signs are strongly linked to the need for IO access in prehospital settings with each successive PIV attempt increasing the likelihood of requiring IO conversion. IO access often accompanies low titer group O whole blood or freeze-dried plasma administration and higher prehospital mortality, indicating its use in emergent resuscitation situations. Early IO consideration is advised for trauma casualties with profound shock.

Objective:To evaluate the clinical efficacy of single-dose arterial infusion chemotherapy（using cisplatin+5-fluorouracil（5-FU）） as a preoperative treatment for locally advanced head and neck malignant tumors, and to reassess tumor burden and lesion extent to guide the development of individualized treatment strategies. Methods:A total of 23 patients with locally advanced head and neck malignant tumors underwent preoperative assessments to determine the extent of the tumor and TNM staging. Treatment options were discussed with the patients and their families. Patients with significant tumor burden and a strong preference for preserving organ function received single-dose arterial infusion chemotherapy, followed by the formulation of an individualized treatment plan. A catheter was inserted through the femoral artery and selectively cannulated into the tumor-supplying artery via the external carotid artery, allowing direct infusion of chemotherapy drugs into the tumor core. Four weeks post-procedure, tumor burden was re-evaluated, and postoperative TNM staging was confirmed, leading to the development of an individualized treatment plan. Results:Among the 23 patients with head and neck malignant tumors, 4 achieved a complete respones（tumor reduction>75%）, 17 achieved a partial response（tumor reduction>50%）. One patient with recurrent oropharyngeal cancer received chemotherapy combined with immunotherapy after the T stage was reduced through treatment. In 113patients with hypopharyngeal cancer and 7 with oropharyngeal cancer, the surgical approach was optimized following treatment. Tow patient with hypopharyngeal cancer showed a stable disease response（tumor reduction>25% or no new lesions）, and after further assessment, a total laryngectomy was deemed appropriate. Conclusion:Among 23 patients with arterial infusion chemotherapy, the T stage of the 21 patients with head and neck malignant tumors decreased, and the local tumor burden was significantly reduced. Additionally, changes were observed in the size, shape, and boundaries of the cervical lymph nodes relative to surrounding tissues.

Transarterial interventional therapy is one of the most widely used treatment methods in patients with primary hepatocellular carcinoma. With the progress in interventional technology and the use of new drugs, transarterial interventional therapy has achieved favorable results in the treatment of primary hepatocellular carcinoma and has become the first choice non-surgical treatment for advanced liver cancer. However, at present, there are great differences in the drugs used in transarterial interventional treatment and the combined application of other drugs among centers, and there is no uniform consensus or guideline. Based on the latest research data and clinical practice experience, as well as the characteristics of Chinese patients, the Specialist Group of Interventional Drugs, Interventionalists Branch of the Chinese Medical Doctor Association was organized to formulate the Chinese expert consensus on intra-arterial drug and combined drug administration for primary hepatocellular carcinoma. The purpose of this consensus is to explore the efficacy and safety of drugs and drug combinations related to intra-arterial interventional therapy, the use of drugs in special populations, the management of adverse reactions, and adjuvant drugs to provide a reference for clinical practice.

Objective: Intraoperative localization of the ureter can contribute to accurate dissection and minimize ureteral injury in colorectal surgery. We aim to summarize a single center's experience of fluorescence ureteral visualization using methylene blue (MB) and explore its visualization efficiency. Methods: This is a descriptive case-series-study. Clinical data of patients who had undergone laparoscopic colorectal surgery and fluorescence visualization of the ureter in the Gastrointestinal Surgery Department of Guangdong Provincial People's Hospital from March 2022 to May 2022 were retrospectively collected. Patients with incomplete surgery videos, renal insufficiency, or allergic reactions were excluded. MB was infused with 0.9% NaCl at 1.0 mg/kg in 100 mL of normal saline for 5 to 15 minutes during laparoscopic exploration. Imaging was performed using a device developed in-house by OptoMedic (Guangdong, China) that operates at 660nm to achieve excitation of MB. Clinical information, MB dosage, rate of successful fluorescence, time to fluorescence, operation time, blood loss, intraoperative blood oxygen levels, pathological staging, changes in renal function, and post-operative complications were retrospectively analyzed. Results: The study cohort comprised 27 patients (24 men and 3 women) with an average age of (60.25±16.95) years and an average body mass index of (21.72±3.42) kg/m². The dosage of MB was 0.3-1.0 mg/kg and the infusion time was 5-15 minutes. Fluorescence signals were detected in all patients. The median time to signal detection was 20 (range, 10 to 40) minutes after MB infusion. The range of intraoperative blood oxygen fluctuation averaged 2.5% (range, 0 to 7.0%). The median change in creatine concentration was -1.3 (range, -17.2 to 29.2) µmol/L. No patients had complications associated with use of MB. Fluorescence visualization of the ureter was very valuable clinically in two patients (thick mesentery, stage T4). Conclusion: MB is a safe and effective means of visualizing the ureter by fluorescence during laparoscopic colorectal surgery, especially when the procedure is difficult. MB in a dosage of less than 1 mg/kg can slowly infused for more than 5 minutes during laparoscopic exploration. During the infusion, attention must be paid to blood oxygen fluctuations.

Objective: To evaluate the efficacy and safety of transcatheter arterial chemoembolization (TACE)-hepatic arterial infusion chemotherapy (HAIC)-targeted-immune quadruple therapy in patients with intermediate and advanced-stage hepatocellular carcinoma (HCC). Methods: 101 patients with intermediate and advanced stage HCC were enrolled according to the inclusion and exclusion criteria, and then they were divided into a combination group and a control group. Patients in the combination group was treated with TACE-HAIC-targeted-immune quadruple therapy, while the control group was only treated with TACE therapy. The overall survival (OS), progression-free survival (PFS), and treatment-related adverse reactions were statistically analyzed in the two groups of patients. Statistical analysis was carried out by t-test, χ² test, rank sum test, Kaplan-Meier curve, log-rank test, Cox regression (or proportional hazards model) analysis according to different data. Results: The tumor objective response rate and disease control rate as evaluated by mRECIST 1.1 criteria in the combination group were 80% and 94%, respectively, which were significantly higher than those in the control group, 41.2% (P<0.001) and 74.5% (P=0.007). The OS and PFS of the combination group were 15.6 months [95%CI 11.3-NA ] and 8.8 months [95%CI 6.9-12.0], respectively, which were significantly better than the control group at 6.1 months [95%CI 5.3-6.6] (P<0.001) and 3.2 months [95%CI 3.0-3.6] (P<0.001). Gastric ulcer incidence was significantly higher in the combination group (9/50, 18%) than that in the control group (2/51, 3.9%) (P=0.023). Conclusion TACE-HAIC-targeted-immune quadruple therapy is a more effective treatment mode for intermediate and advanced-stage HCC than TACE alone, and attention should be paid to the monitoring of target immune-related adverse reactions.

Gastric cancer is one of the most common malignancy in China. Most of the patients of gastric cancer treated clinically are in advanced stage. In the past years, with the progress of anti-cancer drug therapy, after the comprehensive treatment based on drugs therapy of inoperative stage IV gastric cancer, some cases can reduce the tumor stage and get the opportunity of radical operation. Some of the patients who underwent surgical treatment can get the chance of long-term survival. The results of REGATTA trial confirmed that palliative surgery plus chemotherapy could not improve the long-term survival of patients with stage IV gastric cancer. Neoadjuvant intraperitoneal plus intravenous chemotherapy can reduce the tumor stage of some cases of stage IV gastric cancer with peritoneal metastasis and receive surgical treatment, so as to gain the chance of long-term survival. Regimen of intraperitoneal hyperthermia chemotherapy combined with PHOENIX trial is expected to improve the conversion operation rate of gastric cancer with peritoneal metastasis. Paclitaxel-based three-drug chemotherapy can reduce the tumor stage of some inoperable advanced gastric cancer and obtain the opportunity of radical operation, improving the disease-free survival rate and overall survival rate of patients, thus has become the cornerstone of conversion therapy for stage IV gastric cancer. Antiangiogenic targeted drug apatinib combined with paclitaxel is safe and reliable, and can be used as an alternative for the conversion therapy of stage IV gastric cancer, which provides a new idea for cytotoxic drugs combined with targeted drugs. In the era of immunotherapy, the combined application and first-line application of immunosuppressive drugs has become a clinical consensus. For advanced Her-2 positive esophagogastric junction adenocarcinoma cases, the successful exploration of the four-drug combination of chemotherapy+ anti-Her-2 targeted drugs+ anti-PD1 monoclonal antibody combined with the first-line therapy has opened up a new era of transformational therapy for stage IV gastric cancer. Gastric cancer is a malignant tumor with high heterogeneity, the classification of stage IV gastric cancer represented by Yoshida classification is based on imaging, and a more reasonable classification method should be developed in combination with gene detection in the future. Based on this, an individualized and accurate conversion therapy plan is formulated, so as to effectively improve the long-term survival of patients with stage IV gastric cancer.

Metformin (MET), an antidiabetic agent, also has antioxidative effects in metabolic-related hypertension. This study was designed to determine whether MET has anti-hypertensive effects in salt-sensitive hypertensive rats by inhibiting oxidative stress in the hypothalamic paraventricular nucleus (PVN). Salt-sensitive rats received a high-salt (HS) diet to induce hypertension, or a normal-salt (NS) diet as control. At the same time, they received intracerebroventricular (ICV) infusion of MET or vehicle for 6 weeks. We found that HS rats had higher oxidative stress levels and mean arterial pressure (MAP) than NS rats. ICV infusion of MET attenuated MAP and reduced plasma norepinephrine levels in HS rats. It also decreased reactive oxygen species and the expression of subunits of NAD(P)H oxidase, improved the superoxide dismutase activity, reduced components of the renin-angiotensin system, and altered neurotransmitters in the PVN. Our findings suggest that central MET administration lowers MAP in salt-sensitive hypertension via attenuating oxidative stress, inhibiting the renin-angiotensin system, and restoring the balance between excitatory and inhibitory neurotransmitters in the PVN.

The long-term survival of heavily pretreated patients with primary peritoneal cancer (PPC) is uncommon. Here, we report on a patient with PPC refractory to multiple lines of intravenous chemotherapy, namely, a combined regimen of paclitaxel and carboplatin, and single regimens of topotecan, docetaxel, cisplatin, and gemcitabine. However, after intraperitoneal (IP) chemotherapy with paclitaxel-cisplatin, the patient's condition improved, and she has been progression-free for more than 4 years. Interestingly, before the IP chemotherapy, the recurrences were limited to the peritoneal cavity. These results suggest that IP recurrence might be a predictor of a good response to IP chemotherapy.

OBJECTIVE: To evaluate the efficacy of volume therapy with sodium acetate Ringer solution during the perioperative period in children with cyanotic congenital heart disease (CHD). METHODS: The children who underwent elective surgery for cyanotic CHD admitted to Shanghai Children's Medical Center Affiliated to the Medical School of Shanghai Jiaotong University from September to December 2018 were divided into three groups according to random number table with the informed consent of their legal representatives. All of the children received volume therapy with infusion of sodium acetate Ringer solution intravenously upon anesthesia induction. The volume of infusion was calculated according to the "4-2-1" formula (group A, the rehydration volume was 4 mL×kg^-1×h^-1 for the first 10 kg body weight, 2 mL×kg^-1×h^-1 for the second 10 kg, and 1 mL×kg^-1×h^-1 for the third 10 kg and above), and the volume was increased by 50% or 100% in groups B and C, respectively. The intravenous infusion lasted for 30 minutes in all the three groups. Arterial blood gas analysis was performed before and 30 minutes after infusion to observe the acid-base status and electrolyte level. Pulse oxygen saturation (SpO₂), heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP) before and 10, 20, 30 minutes after infusion, central venous pressure (CVP) at 30 minutes after infusion were recorded, as well as adverse events occurred after infusion. RESULTS: Twenty-six children with cyanotic CHD, 17 male and 9 female, aged from 1 to 36 months, body weight 3.6 to 16.0 kg, and America Society of Anesthesiologists (ASA) level of III or IV, were enrolled in the study. The pH value in group B at 30 minutes after infusion was significantly higher than that before infusion (7.35±0.05 vs. 7.32±0.06, P < 0.05), while no significant changes were found before and after infusion in the other two groups. The hematocrits (Hct) after infusion in three groups were significantly lower than those before infusion (0.433±0.141 vs. 0.473±0.146 in group A, 0.324±0.054 vs. 0.372±0.063 in group B, 0.363±0.097 vs. 0.418±0.111 in group C, all P < 0.01), indicating that all the children in the three groups achieved effective hemodilution. However, there was no significant difference in blood gas analysis before and after infusion among the three groups. The level of blood lactic acid (Lac) in all CHD children was decreased from (1.33±0.63) mmol/L to (0.98±0.36) mmol/L after infusion of sodium acetate Ringer solution, the serum Ca²⁺ concentration was decreased from (1.22±0.06) mmol/L to (1.19±0.06) mmol/L, and the serum Cl^- concentration was increased from (108.74±2.70) mmol/L to (109.77±2.54) mmol/L with the statistically significant differences (all P < 0.01). However, no significant difference was found in Lac or electrolyte levels before and after infusion among the three groups. There was no significant difference in vital signs before and after infusion among the three groups, but the period of infusion had an effect on SpO₂ (F = 5.998, P < 0.01), HR (F = 34.279, P < 0.01) and SBP (F = 4.345, P < 0.05). HR in groups A and C were significantly lower than those before infusion, and SBP in group A was decreased gradually with the prolongation of infusion time. The CVP value at 30 minutes after infusion in group B was higher than that in group A. No adverse reactions such as rash or anaphylactic shock occurred after infusion of sodium acetate Ringer solution in all children. CONCLUSIONS The perioperative volume therapy with sodium acetate Ringer solution in children with cyanotic CHD can effectively prevent the increase in Lac level and does not aggravate metabolic acidosis. The volume of infusion was well tolerated by all the children without disturbing the hemodynamic parameters.
