Objective: To evaluate the application of blood conservation measures in obstetric patients with different red blood cell transfusion volumes and to assess the impact of different transfusion volumes on postpartum outcomes. Methods: A retrospective investigation was conducted on 448 obstetric patients who received blood transfusions at the Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from January 2016 to December 2022. Patients were divided into four groups (1-2 units group, 3-4 units group, 5-6 units group, and >6 units group) based on the volumes of red blood cells (RBCs) transfused during and within 7 days after delivery. The maternal physiological indicators, pre- and postpartum laboratory test indicators, obstetric complications, application of blood conservation measures, use of blood products, and postpartum outcomes were reviewed. The clinical characteristics, application of blood conservation measures, and their impact on postpartum outcomes were compared among different transfusion groups. Results: There were statistically significant differences in the multivariate logistic analysis of history of previous cesarean section (OR=1.781), eclampsia/pre-eclampsia/(OR=1.972) and postpartum blood loss>1 000 mL（OR=1.699）(P<0.05) among different transfusion groups. In terms of blood conservation measures, the more RBCs transfused, the higher the rate of mothers receiving blood conservation measures such as balloon occlusion, arterial ligation, autologous blood transfusion with a cell saver, and hysterectomy. With the increase in the volume of RBCs transfusion, the demand for fresh frozen plasma（FFP）, cryoprecipitate, and platelet transfusions also increased. The hospitalization days for the four groups of parturients were 6.0 (4.0-9.0), 7.5 (5.0-14.8), 7.0 (4.5-13.0) and 11.0 (9.0-20.5), respectively (P<0.05) and the rates of ICU transfer were 2.0% (5/250), 9.4% (12/128),18.2% (6/33) and 51.4% (19/37), respectively (P<0.05). Both increased significantly with the increase in the volume of RBCs transfusion, and the differences between groups were statistically significant. Conclusion: Parturients who received higher volume of RBCs had multiple risks factors for bleeding before childbirth, had higher postpartum blood loss, and had a higher rate of application of various blood conservation measures. In addition, an increase in the volume of RBCs transfusion may have adverse effects on postpartum recovery.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To investigate the effect of degree of lower extremity arterial disease in treatment of diabetic foot ulcer with platelet-rich gel. Methods A total of 129 patients with diabetic foot ulcer were selected as the study objects. According to ankle-brachial index and lower extremity artery vascular ultrasound results, 49 cases were divided into mild group (49 cases), moderate group (44 cases) and severe group (36 cases). All patients in three groups were given conventional treatment combined with platelet-rich gel therapy. The changes of ulcer area and granulation area before and after treatment in three groups were compared. Results The ulcer area and its difference value before and after treatment among the three groups were statistically significant (P<0.05). The granulation tissue area and its difference value before and after treatment among the three groups showed statistical significance (P<0.05). The difference value in ulcer area was positively correlated with ankle-brachial index (r=0.392, P<0.001), and negatively correlated with diabetes course (r=-0.420, P<0.001); the difference value in granulation area was positively correlated with ankle-brachial index (r=0.406, P<0.001) and negatively correlated with diabetes course (r=-0.375, P<0.001). Conclusion The more severe the lower extremity artery lesionsis, the worse the therapeutic effect of platelet-rich gel on diabetic foot ulcer will be.

This paper summarized clinical experience of treating recurrent subacute thyroiditis based on the theory of internal toxin. It is believed that the core pathogenesis of recurrent subacute thyroiditis is the accumulation of internal toxin. The dysfunction of the spleen in transportation leads to the internal retention of turbidity， which serves as the basis for the formation of toxins. The combination of fire， dampness， and toxins is the key to the disease mechanism. Prolonged accumulation of dampness and turbidity leads to the formation of phlegm， fire， and stasis， and prolonged accumulation of pathogenic factors transforms into secondary toxins. For patients with severe fire， dampness， and toxins， the treatment focuses on dispersing stagnated liver qi， invigorating spleen， and differentiation treatment of fire and water， using a self-designed Chaihu Jiedu Decoction （柴胡解毒饮）. For patients with spleen deficiency and toxin accumulation， the treatment focuses on invigorating the spleen， eliminating turbidity， and cutting off the source of toxins， using a self-designed Shiwei Baizhu Powder （十味白术散）. For patients with yang deficiency and toxin stagnation， detoxification is combined with warming yang， nourishing blood， and supporting toxin expulsion， using a self-designed Heyang Baidu powder （和阳败毒散）.

Objective:To investigate the effect of vascularized lymph node transfer (VLNT) combined with lymphatico-venous anastomosis (LVA) in the treatment of lymphedema after breast cancer surgery.Methods:The data of patients with upper limb lymphedema after breast cancer surgery who were treated in the Department of Reconstructive and Reconstructive Microsurgery, Ruikang Hospital Affiliated to Guangxi University of Traditional Chinese Medicine from July 2021 to July 2022 were retrospectively analyzed. According to different treatment methods, the patients were divided into LVA group and VLNT combined LVA group. Indocyanine green (ICG) near-infrared lymphography was performed on all affected limbs before surgery. In the LVA group, according to the results of ICG lymphography, 4 to 5 levels of the affected limb were selected, Z shaped incisions were made and dissescted until the subcutaneous fat layer. End-to-end or end-to-side anastomosis was performed between lymphatic vessels and subcutaneous venules under the microscope. In the VLNT combined LVA group, the branches of brachial artery and vein in the axillary region were marked. The inguinal flap with the superficial iliac circumflex vessel pedicle and 4-5 lymph nodes was dissected. End-to-end anastomoses of the superficial iliac circumflex vessel pedicle with the branches of brachial artery and vein were performed in the axillary region of the affected limb. LVA was performed according to ICG lymphography, the same as in the LVA group. The skin and soft tissue condition of the affected limb and the blood supply of the flap in the VLNT combined LVA group were observed after operation. The circumference of the upper arm (from the wrist to 32 cm above the wrist, every 4 cm, a total of 9 levels of circumference) and upper limb volume were measured before and after operation. SPSS 24.0 was used for data processing and analysis. Measurement data were expressed Mean±SD. The data before and after operation in the same group were compared by paired samples t test, and the comparison between the two groups was conducted by independent samples t test. P<0.05 was considered statistically significant. Results:A total of 14 female patients were enrolled, with 7 patients in each group. All cases were unilateral lymphedema. There were no significant differences in age, stage of disease, limb circumference and limb volume between the two groups before operation ( P>0.05). After operation, the skin and soft tissue condition of the affected limbs were good, and no complications such as erysipelas, cellulitis, or lymphangitis occurred. All flaps in the VLNT combined LVA group survived successfully, and the operation wounds healed well. There were no complications such as infection and necrosis of the flaps. One year after operation, the circumference and volume of the affected limb in the two groups were improved to varying degrees, and the circumference of the affected limb (wrist, upper wrist 4, 8, 12, 16, 20, 24, 28, 32 cm levels) in the VLNT combined LVA group was significantly smaller than that before operation ( P<0.01). In the LVA group, the circumference of the affected limb (wrist, upper wrist 4, 8, 12, 16, 20 cm levels) after operation was significantly smaller than that before operation ( P<0.05). The limb volumes of both groups were significantly reduced ( P<0.05). The comparison between the two groups showed that the reduction degree of postoperative affected limb cricumference (at the levels of 24, 28 and 32 cm above the wrist) and volume in the VLNT combined LVA group were more significant than those in the LVA group ( P<0.05). Conclusion:Compared with LVA alone, VLNT combined with LVA is more effective in the treatment of patients with upper limb lymphedema after breast cancer surgery.

OBJECTIVES: Radiotherapy is one of the main therapies for colorectal cancer, but radioresistance often leads to radiotherapy failure. To improve the radioresistance, we explore the effect of oligomycin A, the H METHODS: The effects of different concentrations of oligomycin A on the survival rate and glycolysis of HT29 colorectal cancer cells at different time points were investigated via MTT and glycolysis assay. siRNA-PFK1 was synthesized in vitro and transfected into HT29 cells. The effects of oligomycin A on radiosensitivity of HT29 colorectal cancer cells were measured via MTT and colony formation assay. Western blotting was used to detect the effect of oligomycin A on the expression of glycolytic enzyme PFK1. We compared difference between the effects of siRNA-PFK1 group and oligomycin A combined with siRNA-PFK1 group on cell survival and glycolysis. After 4 Gy X-ray irradiation, the effects of cell survival and glycolysis between the siRNA-PFK1 group and the oligomycin A combined with siRNA-PFK1 group were compared. RESULTS: Compared with the 0 μmol/L oligomycin A group, the cell survival rate of HT29 cells treated with 4 μmol/L oligomycin A was significantly increased ( CONCLUSIONS Oligomycin A can promote the radioresistance of HT29 colorectal cancer cells, which may be related to up-regulation of the PFK1 expression and increase of cell glycolysis.

Occupational exposure to 1-bromopropane (1-BP) induces learning and memory deficits. However, no therapeutic strategies are currently available. Accumulating evidence has suggested that N-methyl-D-aspartate receptors (NMDARs) and neuroinflammation are involved in the cognitive impairments in neurodegenerative diseases. In this study we aimed to investigate whether the noncompetitive NMDAR antagonist MK801 protects against 1-BP-induced cognitive dysfunction. Male Wistar rats were administered with MK801 (0.1 mg/kg) prior to 1-BP intoxication (800 mg/kg). Their cognitive performance was evaluated by the Morris water maze test. The brains of rats were dissected for biochemical, neuropathological, and immunological analyses. We found that the spatial learning and memory were significantly impaired in the 1-BP group, and this was associated with neurodegeneration in both the hippocampus (especially CA1 and CA3) and cortex. Besides, the protein levels of phosphorylated NMDARs were increased after 1-BP exposure. MK801 ameliorated the 1-BP-induced cognitive impairments and degeneration of neurons in the hippocampus and cortex. Mechanistically, MK801 abrogated the 1-BP-induced disruption of excitatory and inhibitory amino-acid balance and NMDAR abnormalities. Subsequently, MK801 inhibited the microglial activation and release of pro-inflammatory cytokines in 1-BP-treated rats. Our findings, for the first time, revealed that MK801 protected against 1-BP-induced cognitive dysfunction by ameliorating NMDAR function and blocking microglial activation, which might provide a potential target for the treatment of 1-BP poisoning.
