Many investigations showed that abnormal blood insulin level is associated with the pathogenesis of Alzheimer′s disease and its clinical manifestation, suggesting that increasing blood insulin level and/or improving insulin sensitivity seem to be helpful for patients with Alzheimer′s disease.

Objective To research the mechanism of TX0201 abstracted from Heart-Regulating Formula in treatment of rats with Alzheimer's disease (AD). Methods The rat model of AD was induced by A?25-35 injected into the bilateral amygdale. To observe the spatial learning and memory ability, by means of RT-PCR and immunohistochemistry analysis, the expression of ?-amyloid precursor protein (APP), glial filament acid protein (GFAP) in the brain of the model animal were examined. Results In AD model group, the spatial learning and memory ability was damaged significantly, the expression of APP mRNA increased in its cortex and hippocampus. GFAP immunopositive signal, and IL-6 mRNA in cortex and hippocampus and the expression of IL-1? mRNA in hippocampus were upregulated. TX0201 improved the spatial learning and memory disturbance, decreased the expression of APP mRNA and IL-1? mRNA in hippocampus, downregulated GFAP and IL-6 mRNA in cortex and hippocampus. Conclusions The model showed the characteristic of AD such as memory hypofunction. TX0201 could partially ameliorate memory function, decrease the expression of APP mRNA in hippocampus, alleviate inflammation-immunity reaction, that is one of the effect mechanisms of TX0201.

Ferroptosis is an iron-dependent novel type of programmed cell death. The main features of ferroptosis include lipid reactive oxygen accumulation, iron accumulation and lipid peroxidation. The main mechanisms and signal pathways of ferroptosis are complex and closely related to cystine/glutamate antiporter system, glutathione peroxidase 4, ferroptosis suppressor protein 1, and dihydroorotate dehydrogenase. This review summarizes the current regulatory mechanisms of ferroptosis and discusses the research progress of ferroptosis in tumors, non-alcoholic fatty liver disease, Parkinson's disease, and congestive heart failure.

Nowadays, the popularization of endoscopic technology makes a substantial increase in the diagnosis rate of esophageal multiple primary carcinoma. However, the multiple primary carcinoma combined with esophageal cancer, lung cancer and cardiac cancer is relatively rare. This paper reported a 64-year-old male with multiple primary cancer who received one-stage complex radical surgery, including radical resection of esophageal cancer, lung cancer and cardiac cancer. After the operation, the patient presented chylothorax and conservative treatment was ineffective. Then we preformed ligation of thoracic duct through single-portal thoracoscope. The patient recovered successfully after surgery and the follow-up results showed well.

Objective:To investigate the short-term efficacy of left-sided three-port total laparoscopic distal gastrectomy (TPTLDG).Methods:The prospective randomized controlled study was conducted. The 68 patients undergoing laparoscopic distal gastrectomy in the First Affiliated Hospital of Air Force Medical University from March 2022 to March 2023 were collected. All patients were randomly assigned to the TPTLDG group with a double number, and to the five-port laparoscopic distal gastrectomy (FPLDG) group with a single number, respectively. Observation indicators: (1) grouping situations of the enrolled patients; (2) comparison of perioperative condition; (3) comparison of complications during postoperative 30 days; (4) comparison of pathological examination. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or continuous correction chi-square test. Comparison of ordinal data was analyzed using the non‐parameter rank sum test. Results:(1) Grouping situations of the enrolled patients. A total of 59 patients of gastric cancer were selected for eligibility. There were 40 males and 19 females, aged 59.00(52.00, 67.00)years. The gender (male, female), age, body mass index (BMI), Caprini score (≤2, ≥3), nutritional risk screening 2002 (<3, ≥3), Eastern Coopera-tive Oncology Group performance status (0, 1), preoperative hypersensitive C-reactive protein, preoperative IL-6, preoperative white blood cell count, preoperative albumin were 19, 11, 59.00(51.25,65.25)years, 21.92(20.93,22.73)kg/m 2, 7, 23, 24, 6, 18, 12, 0.78(0.78,1.46)mg/L, 3.07(1.50,10.56)μg/L, 6.07(4.94,7.19)×10 9/L, 44.30(40.83, 46.15) g/L in the 30 patients of TPTLDG group, versus 21, 8, 57.00(51.00, 67.00)years, 21.90(20.95, 23.35)kg/m 2, 11, 18, 24, 5, 17, 12, 1.13(0.78,11.40)mg/L, 5.56(1.88,15.12)μg/L, 5.54(4.71,6.70)×10 9/L, 43.55(40.25,44.88)g/L in the 29 patients of FPLDG group, showing no significant difference in the above indicators between the two groups ( χ2=0.557, Z=-0.444, -0.805, χ2=1.482, 0.074, 0.012, Z=-1.259, -1.262, -0.819, -1.199, P>0.05), confounding bias ensured comparability between the two groups. (2) Comparison of perioperative condition. The length of incision, time to removing drainage tube, IL-6 at postoperative day 3, cost of hospital stay were 6.65(6.48,6.93)cm, 3.00(0,3.00)days, 29.18 (13.67, 43.53)μg/L, 84 164.15(73 084.72, 96 782.14)yuan in the TPTLDG group, versus 8.00(7.50,8.35)cm, 3.00(3.00,4.00)days, 47.56(21.31,85.79)μg/L, 92 120.43(87 069.33, 113 089.74)yuan in the FPLDG group, showing significant differences in the above indicators between the two groups ( Z=-11.065, -2.141, -2.940, -2.220, P<0.05). (3) Comparison of complications during postoperative 30 days. The incidence rate of complications during postoperative 30 days was 30.00%(9/30) and 24.14%(7/29) in the TPTLDG group and FPLDG group, respectively, showing no significant difference between the two groups ( χ2=0.256, P>0.05). (4) Comparison of pathological examination. Cases with pathological N staging as 0 stage, 1 stage, 2 stage, 3 stage were 22, 2, 4, 2 in the TPTLDG group, versus 13, 7, 4, 5 in the FPLDG group, showing a significant difference between the two groups ( Z=-2.021, P<0.05). Conclusion:TPTLDG is safe and feasible for gastric cancer, with a good short-term efficacy.

SARS-CoV-2 infection causes complicated clinical manifestations with variable multi-organ injuries, however, the underlying mechanism, in particular immune responses in different organs, remains elusive. In this study, comprehensive transcriptomic alterations of 14 tissues from rhesus macaque infected with SARS-CoV-2 were analyzed. Compared to normal controls, SARS-CoV-2 infection resulted in dysregulation of genes involving diverse functions in various examined tissues/organs, with drastic transcriptomic changes in cerebral cortex and right ventricle. Intriguingly, cerebral cortex exhibited a hyperinflammatory state evidenced by significant upregulation of inflammation response-related genes. Meanwhile, expressions of coagulation, angiogenesis and fibrosis factors were also up-regulated in cerebral cortex. Based on our findings, neuropilin 1 (NRP1), a receptor of SARS-CoV-2, was significantly elevated in cerebral cortex post infection, accompanied by active immune response releasing inflammatory factors and signal transmission among tissues, which enhanced infection of the central nervous system (CNS) in a positive feedback way, leading to viral encephalitis. Overall, our study depicts a multi-tissue/organ transcriptomic landscapes of rhesus macaque with early infection of SARS-CoV-2, and provides important insights into the mechanistic basis for COVID-19-associated clinical complications.
