Ferroptosis is a form of iron-dependent cell death caused by a disorder of iron lipid metabolism.Its mechanism mainly includes lipid metabolism and iron metabolism,which are complicated and strictly regulated by various metabolic and signaling pathways.Current studies have shown that ferroptosis is associated with cancer,atherosclerosis,and neurological diseases.Traditional Chinese medicine(TCM)is characterized by various active ingredients,relatively high safety,and lower treatment costs,which possess unique advantages in clinical applications.It has been widely used in the treatment of various diseases.Taking the regulation of ferroptosis by traditional Chinese medicine as the entry point may be a new direction for the future prevention and treatment of various diseases.In this review,we discussed the mechanism of iron lipid metabolic disorders based on ferroptosis and the research progress of traditional Chinese medicine intervention to provide reference and treatment strategies for the prevention and treatment of related diseases.

Objective:To investigate the clinical effect of proper management of inferior pancreaticoduodenal artery (IPDA) in laparoscopic pancreaticoduodenectomy (LPD).Methods:This is a retrospective case series study. The clinical and pathological data of 70 patients who received LPD due to pancreatic head tumors, periampullary tumors, or distal common bile duct tumors in the Pancreatic Center of the Second Clinical College of Guangzhou University of Chinese Medicine from January to December 2022 were retrospectively collected. There were 47 males(67.1%) and 23 females(32.9%),aged (59.9±12.8)years(range:13 to 87 years).The procedure of IPDA exposure was as follows:a middle approach was utilized to expose the right half of superior mesenteric artery(SMA) and its right branches between the SMA and superior mesenteric vein(SMV) in superior colonic region. In the subcolonic region,SMA trunk exposure via dissection along the jejunal artery from feet to head and identification the association between IPDA and jejunal artery were prior to IPDA root ligation and dissection. The safety and efficacy of intraoperative IPDA handling were assessed based on surgical videos. Follow-up was carried out in outpatient clinic or by telephone, and outpatient follow-up was conducted once every 1 to 3 months after surgery.Results:The percentage of total LPD was 98.6%(69/70),with all patients achieving R0 resection. Nine cases(12.9%) were involved in combined vascular resection and reconstruction,with 1 case (1.4%) requiring additional upper abdominal incision for vascular and gastrointestinal reconstruction,while the remaining eight cases (11.4%) were completed laparoscopically. The operative time was (432.7±115.4)minutes(range:282 to 727 minutes), and the blood loss was (140.0±125.7)ml(range:20 to 800 ml). Only two patients(2.9%) received fresh frozen plasma transfusion,with an average volume of 650 ml. Reliable ligation and safe handling of the IPDA were achieved in 91.4%(64/70) of cases, with 8.6%(6/70) suffering from IPDA injury-related bleeding. No one was converted to opened surgery. Pathologically,the mean tumor size was (3.3±1.6)cm (range:1 to 7 cm),and the mean number of harvested lymph nodes was 17.0±7.3(range:0 to 46). Lymph node metastasis was observed in 13 cases (18.6%). Five cases (13.2%) developed grade B pancreatic fistula,while no grade C pancreatic fistula occurred. Other complications included bile leakage in one case(1.4%),delayed gastric emptying in two cases(2.9%), lymphatic leakage in 2 cases(2.9%),intra-abdominal infection in 9 cases(12.9%),and fat liquefaction of surgical incision in 1 case(1.4%). Two cases(2.9%) experienced postoperative intra-abdominal bleeding,one due to mesangial bleeding of lesser curvature of the stomach and the other due to oozing from the hepatic arterial sheath. These bleeding events were not concerned with IPDA. The average length of postoperative hospital stay was (15.2±4.6)days(range:9 to 28 days).Conclusion:Proper intraoperative management of IPDA in LPD might reduce IPDA-related bleeding during and after surgery and improve the safety of LPD.

Objective:To explore the safety and feasibility of bilateral axillo-breast approach （BABA） robot in the operation of thyroid cancer in obese women. Methods:The clinical data of 81 obese female patients who underwent da Vinci robotic thyroid cancer surgery（robotic group） at the Department of Thyroid and Breast Surgery, PLA 960 Hospital from May 2018 to December 2021 were retrospectively analyzed and compared with the clinical data of 106 obese female thyroid cancer patients who underwent open surgery（open group） during the same period. The age, body mass index（BMI）, mean time of surgery, mean postoperative drainage, tumor diameter, postoperative tumor stage, number of lymph node dissection in the central and lateral cervical regions, number of positive lymph nodes in the central and lateral cervical regions, postoperative cosmetic outcome satisfaction score, mean postoperative hospital stay and postoperative complications of all patients were counted. The results were analyzed using SPSS 26.0 statistical software, and the count data were compared using the χ² test, and the measurement data were compared using the t test. Results:All patients completed the operation successfully, and there was no conversion in the robot group, postoperative pathological results were all composed of papillary thyroid carcinoma. The operation time in the robot group was（144.62±36.38） min, which was longer than that in the open group（117.06±18.72） min（P<0.05）. The average age of the robot group was（40.25±9.27） years, which was lower than that of the open group（49.59±8.70） years（P<0.05）. The satisfactory score of cosmetic effect in the robot group（9.44±0.65） was higher than that in the open group（5.23±1.07）（P<0.05）. There was no significant difference in tumor diameter, BMI, average postoperative drainage, temporary hypoparathyroidism and recurrent laryngeal nerve injury, number of central and lateral cervical lymph node dissection, number of positive lymph nodes in the central and lateral cervical regions, and average postoperative hospital stay between the two groups. There was no permanent hypoparathyroidism and recurrent laryngeal nerve injury in both groups. Conclusion:The application of BABA pathway robot in thyroid cancer surgery in obese women is safe and feasible, and the cosmetic effect is better after operation.

Objective: To evaluate the safety and feasibility of Da Vinci robot in the treatment of thyroid cancer with hyperthyroidism via bilateral axillo-breast approach (BABA). Methods: The clinical data of 21 patients with thyroid cancer complicated with hyperthyroidism who received thyroidectomy + central lymph node dissection and(or)neck lymph node dissection using the Da Vinci through axillo-bilateral-breast approach in the thyroid and breast surgery of the 960th Hospital of the PLA Joint Logistics Support Force, from February 2014 to February 2019 were analyzed retrospectively. The clinical data of 21 patients were used as observation group, including 5 males and 16 females, aged (46.03±3.08) years. At the same period, 19 patients with the thyroid cancer complicated with hyperthyroidism who underwent traditional open surgery were selected as the control group, including 5 males and 14 females, aged (47.06±2.03) years. The t test, rank sum test, and χ² test were used to compare the operation time, postoperative hospital stay, postoperative drainage volume, postoperative pain (VAS), cosmetic outcome satisfaction, and related surgical complications between the two groups. Results: All the patients of the two groups completed the operation successfully. The operation time of the observation group was longer than that of the control group [(191.12±3.17) vs (145.37±6.37) min, P<0.05]; The postoperative pain degree score of the observation group was lower than that of the control group [(3.40±1.12) points vs (5.10±1.19) points, P<0.05]. The cosmetic effect score of the observation group was better than that of the control group [(9.10±3.03) points vs (5.05±1.02) points, P<0.05]. There were no significant differences in the amount of intraoperative blood loss, mean postoperative drainage, postoperative hospital stay, central lymph node metastasis and complication rate between the two groups (P>0.05). There was no significant difference in Tg level and recurrence rate between the two groups (P>0.05). Conclusion Da Vinci robotic assisted treatment for thyroid cancer with hyperthyroidism is safe and feasible, which with good cosmetic and privacy protection effects.
