Study on the mechanism of Fangxia Dihuang Formula(FXDH) in treating breast cancer complicated with depression through the regulation of M1/M2 microglial polarization via the PERK/eIF2α axis. In addition to control group and 4T1 group, a mouse model of breast cancer complicated with depression was established using 4T1 cells combined with corticosterone. The mice were divided into model group, PERK/eIF2α signaling axis agonist(CCT020312, 2 mg·kg~(-1)·d~(-1)) group, CCT020312(2 mg·kg~(-1)·d~(-1)) + FXDH(13.65 g·kg~(-1)·d~(-1)) group, FXDH(13.65 g·kg~(-1)·d~(-1)) group, FXDH(13.65 g·kg~(-1)·d~(-1)) + Capecitabine Tablets(CAP, 390 mg·kg~(-1)·d~(-1)) group, and Fluoxetine Hydrochloride Capsules(FXT, 2.6 mg·kg~(-1)·d~(-1)) + CAP(390 mg·kg~(-1)·d~(-1)) group, with continuous intervention for 21 d. Depression-like behaviors in mice were assessed through sugar preference test and open field test. Hematoxylin-eosin(HE) staining was used to evaluate the morphology of tumor and hippocampal DG region neurons. Nissl staining was employed to detect changes in Nissl bodies in the hippocampal CA3 region. Immunofluorescence was used to observe cluster of differentiation 86(CD86)/ionized calcium-binding adapter molecule 1(Iba-1) and cluster of differentiation 206(CD206)/Iba-1 in hippocampal tissue. Real-time fluorescence quantitative polymerase chain reaction(RT-qPCR) was used to detect the mRNA expression of M1-type microglia [interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)] and M2-type [arginase-1(Arg-1), IL-10] in hippocampal tissue. Western blot was used to detect the protein expression of key factors in the PERK/eIF2α axis, including PERK, eIF2α, activating transcription factor 4(ATF4), and C/EBP homologous protein(CHOP) in hippocampal tissue. The results showed that compared to model group/CCT020312 + FXDH group, FXDH group increased sugar preference index, total movement distance, central zone distance, and central zone entries; reduced tumor mass and volume; tumor cells were sparsely arranged, with a smaller nuclear-to-cytoplasmic ratio and reduced nuclear division figures, increased Nissl body count, and alleviated neuronal nuclear pyknosis; increased CD206-positive M2-type microglia expression, decreased CD86/Iba-1-positive M1-type microglia expression; reduced IL-6 and TNF-α mRNA expression, and increased Arg-1 and IL-10 mRNA expression; downregulated PERK, eIF2α, ATF4, and CHOP protein expression levels. The results indicate that the mechanism of FXDH in treating breast cancer complicated with depression may be related to inhibiting the activity of the PERK/eIF2α axis, reducing the proportion of M1-type microglia, increasing the proportion of M2-type microglia, thereby suppressing neuronal immune inflammation, improving depressive symptoms, and subsequently delaying the progression of breast cancer.

OBJECTIVE: To investigate the associations between eight serum per- and polyfluoroalkyl substances (PFASs) and regional fat depots, we analyzed the data from the National Health and Nutrition Examination Survey (NHANES) 2011-2018 cycles. METHODS: Multiple linear regression models were developed to explore the associations between serum PFAS concentrations and six fat compositions along with a fat distribution score created by summing the concentrations of the six fat compositions. The associations between structurally grouped PFASs and fat distribution were assessed, and a prediction model was developed to estimate the ability of PFAS exposure to predict obesity risk. RESULTS: Among females aged 39-59 years, trunk fat mass was positively associated with perfluorooctane sulfonate (PFOS). Higher concentrations of PFOS, perfluorohexane sulfonate (PFHxS), perfluorodecanoate (PFDeA), perfluorononanoate (PFNA), and n-perfluorooctanoate (n-PFOA) were linked to greater visceral adipose tissue in this group. In men, exposure to total perfluoroalkane sulfonates (PFSAs) and long-chain PFSAs was associated with reductions in abdominal fat, while higher abdominal fat in women aged 39-59 years was associated with short-chain PFSAs. The prediction model demonstrated high accuracy, with an area under the curve (AUC) of 0.9925 for predicting obesity risk. CONCLUSION PFAS exposure is associated with regional fat distribution, with varying effects based on age, sex, and PFAS structure. The findings highlight the potential role of PFAS exposure in influencing fat depots and obesity risk, with significant implications for public health. The prediction model provides a highly accurate tool for assessing obesity risk related to PFAS exposure.

It can objectively evaluate the quality management level, facilitate the continuous improvement of the quality management system, promote the homogenization of blood management in the province and lay the foundation for future comprehensive evaluation of blood banks.

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 develop an expert consensus on safety management of inpatients with Alzheimer's disease (AD) (referred to as the " Consensus") and standardize safety management strategies for AD inpatients. Methods:The evidence on safety management of AD inpatients was searched, evaluated, and summarized, with a search period from database establishment to July 31, 2023. This study conducted methodological quality evaluation and evidence extraction on the included article to form a consensus draft. A total of 24 experts from 15 hospitals across the country were selected for two rounds of Delphi expert consultation to analyze, revise, and improve their opinions, forming the final draft of the Consensus. Results:The positive coefficients for both rounds of expert consultation were 100.00% (24/24). In the second round of consultation, the expert judgment basis coefficient was 0.925, familiarity level was 0.846, authority coefficient was 0.886, Kendall harmony coefficient was 0.044 ( P<0.01). The Consensus elaborated on five common safety problems (loss, falling, aspiration/choking, self-injury/other injury, and medication errors in AD inpatients) from three aspects (assessment, identification of risk factors, and nursing strategies) . Conclusions:The Consensus is scientific and practical to a certain extent, providing guidance and reference for the safety management practice of AD inpatients.

Objective To investigate the relationship between appendicular skeletal muscle composition(muscle mass and muscle index)and glycosylated hemoglobin A1c(HbA1c)level in type 2 diabetes mellitus(T2DM)patients.Methods A total of 459 adult T2DM patients hospitalized in the Department of Endocrinology,Tangdu Hospital of Air Force Medical University from April 2021 to June 2022 were selected as the research objects.Bioelectrical impedance analysis was used to evaluate the body composition of the patients.The patients were divided into two groups according to HbA1c level:standard glycation group(HbA1c≤7.0%,n=145)and unqualified glycation group(HbA1c>7.0%,n=314).The two groups'general data,biochemical indexes,muscle content,fat content and other body composition were analyzed.Spearman correlation analysis and multiple logistic regression analysis were used to analyze the relationship between body composition and glycemic control in type 2 diabetic patients.Results The appendicular skeletal muscle mass and its index(ASMI)of the patients in the standard glycation group were better than those in the unqualified glycation group(P<0.05).However,there were no significant differences in gender,history of antidiabetic drugs and body fat(body fat content,limb fat content and visceral fat content)between the two groups(P>0.05).Spearman correlation analysis showed that appendicular skeletal muscle mass and its index were negatively correlated with HbA1c(r=-0.158,P=0.001;r=-0.187,P<0.001).Logistic regression analysis showed that upper limb skeletal muscle mass(OR=3.570,95%CI 2.293-5.559)and lower limb skeletal muscle mass(OR=1.297,95%CI 1.146-1.468)were independent protective factors for achieving glycation standard in HbA1c group.Conclusions The skeletal muscle mass of limbs is a protective factor for reaching the standard of HbA1c.With the increase of skeletal muscle mass of limbs,the level of HbA1c gradually decreases.Among them,the increase of upper limb muscle mass has a stronger correlation with reaching the standard of HbA1c.

Objective:To analyze the status of neonatal respiratory distress syndrome (RDS) management in 10 hospitals in Northwest China over the past five years and to investigate the strategies for improving the prevention and treatment of RDS.Methods:This retrospective study involved premature infants with RDS who were admitted to the neonatal intensive care units (NICU) of 10 hospitals (six in Shaanxi Province, three in Gansu Province, and one in Xinjiang Uygur Autonomous Region) of the Northwest China Neonatal Collaborative Group within 3 d after birth from January 1 to December 31, 2016, and from January 1 to December 31, 2021. Basic information, perinatal condition, treatment approaches, complications, and prognosis of the patients were compared. T-test, rank sum, and Chi-square tests were used for statistical analysis. Result:(1) This study enrolled 322 premature infants with RDS in 2016 and 349 in 2021. Premature infants at the gestational age of 30 to 33 weeks were mainly affected, and the majority were male [64.3% (207/322) and 57.3% (200/349)]. The average maternal age in 2021 was older than that in 2016 [(30.6±4.8) years vs (28.6±5.4) years, t=24.02, P<0.001], and the proportion of women at advanced maternal age was also higher in 2021 [19.2% (67/349) vs 12.4% (40/322), χ2=4.18, P<0.05]. (2) The proportions of pregnancies conceived with assisted reproductive technologies [11.7% (41/349) vs 1.9% (6/322), χ2=25.12], underwent routine prenatal examinations [58.5% (204/349) vs 30.4% (98/322), χ2=53.33], exposed to steroids [62.2% (217/349) vs 28.6% (92/322), χ2=82.58] and delivered by cesarean section or elective cesarean section [73.6% (257/349) vs 51.6% (166/322), χ2=35.06; 24.1% (84/349) vs 6.5% (21/322), χ2=39.07], as well as the ratio of cesarean scar pregnancy [7.4% (26/349) vs 3.4% (11/322), χ2=5.23] were all higher in 2021 than those in 2016 (all P<0.05). Moreover, the incidence of fetal distress [30.1% (105/349) vs 20.2% (65/322), χ2=8.68], gestational hypertension [24.6% (86/349) vs 13.0% (42/322), χ2=14.59], premature rupture of membranes [16.0% (56/349) vs 10.2% (33/322), χ2=4.89], meconium-stained amniotic fluid [12.6% (44/349) vs 5.6% (18/322), χ2=9.83], placental abruption [10.3% (36/349) vs 5.3% (17/322), χ2=5.84], gestational diabetes mellitus [10.3% (36/349) vs 1.6%(5/322), χ2=22.41], chorioamnionitis [4.6%(16/349) vs 0.9% (3/322), χ2=8.12], thyroid dysfunction [4.3% (15/349) vs 0.6% (2/322), χ2=7.88] and heart disease [4.3% (15/349) vs 0.3% (1/322), χ2=9.17] were higher in 2021 than in 2016 (all P<0.05). (3) In 2021, the rate of pulmonary surfactant (PS) usage, the dosage of porcine PS, and the proportion of bovine PS usage were all significantly higher than those in 2016 [73.6% (257/349) vs 67.1% (216/322), χ2=11.62; (178.5±38.0) mg/kg vs (165.2±42.8) mg/kg, t=7.85; 47.9% (123/257) vs 19.4% (42/216), χ2=41.72; all P<0.01]. No significant difference in the incidence of intubation-surfactant-extubation (INSURE), early PS administration (≤2 h after birth), or the arterial blood gas values before and after PS treatment was found between the cases enrolled in 2021 and 2016. The duration of antibiotic treatment [7.0 d (5.0-14.0 d) vs 5.0 d (1.0-8.0 d), Z=7.55] and assisted ventilation [144 h (81-264 h) vs 73 h (47-134 h), Z=8.20] and the median hospital stay [24 d(14-42 d) vs 16 d (10-25 d), Z=6.74] were significantly longer in 2021 than in 2016 (all P<0.01). More patients required nasal intermittent positive pressure ventilation [29.6% (100/338) vs 1.0% (3/306), χ2=97.81] and conventional ventilation [42.6% (144/338) vs 30.1% (92/306), χ2=10.87] in 2021 as compared with those five years ago (both P<0.01).

(5) The cure rate of premature infants with RDS was 70.8% (247/349) in 2021, which was significantly higher than that in 2016 [56.2% (181/322), χ2=15.37, P<0.001]. Moreover, the rate of withdrawing treatment and the total mortality rate was lower in 2021 than in 2016 [7.7% (27/349) vs 14.3% (46/322), χ2=7.41; in-hospital: 1.4% (5/349) vs 5.6% (18/322), χ2=8.74; out of hospital: 8.3% (29/349) vs 13.7% (44/322), χ2=4.96; all P<0.05]. Conclusions:The clinical management of RDS in premature infants in the involved hospitals has been improved. However, there is room for improvement in prenatal examinations.

Objective: To evaluate the efficacy of surgical treatment of aortic coarctation combined with descending aortic aneurysm in adult patients. Methods: This is a retrospective cohort study. Adult patients with aortic coarctation who were hospitalized in Beijing Anzhen Hospital from January 2015 to April 2019 were enrolled. The aortic coarctation was diagnosed by aortic CT angiography, and the included patients were divided into the combined descending aortic aneurysm group and the uncomplicated descending aortic aneurysm group based on descending aortic diameter. General clinical data and surgery-related data were collected from the included patients, and death and complications were recorded at 30 days after surgery, and upper limb systolic blood pressure was measured in all patients at discharge. Patients were followed up after discharge by outpatient visit or telephone call for their survival and the occurrence of repeat interventions and adverse events, which included death, cerebrovascular events, transient ischemic attack, myocardial infarction, hypertension, postoperative restenosis, and other cardiovascular-related interventions. Results: A total of 107 patients with aortic coarctation aged (34.1±15.2) years were included, and 68 (63.6%) were males. There were 16 cases in the combined descending aortic aneurysm group and 91 cases in the uncomplicated descending aortic aneurysm group. In the combined descending aortic aneurysm group, 6 cases (6/16) underwent artificial vessel bypass, 4 cases (4/16) underwent thoracic aortic artificial vessel replacement, 4 cases (4/16) underwent aortic arch replacement+elephant trunk procedure, and 2 cases (2/16) underwent thoracic endovascular aneurysm repair. There was no statistically significant difference between the two groups in the choice of surgical approach (all P>0.05). In the combined descending aortic aneurysm group at 30 days after surgery, one case underwent re-thoracotomy surgery, one case developed incomplete paraplegia of the lower extremity, and one case died; and the differences in the incidence of endpoint events at 30 days after surgery were similar between the two groups (P>0.05). Systolic blood pressure in the upper extremity at discharge was significantly lower in both groups compared with the preoperative period (in the combined descending aortic aneurysm group: (127.3±16.3) mmHg vs. (140.9±16.3) mmHg, P=0.030, 1 mmHg=0.133 kPa; in the uncomplicated descending aortic aneurysm group: (120.7±13.2) mmHg vs. (151.8±26.3) mmHg, P=0.001). The follow-up time was 3.5 (3.1, 4.4) years. There were no new deaths in the combined descending aortic aneurysm group, no transient ischemic attack, myocardial infarction or re-thoracotomy surgery, and one patient (1/15) suffered cerebral infarction and 10 patients (10/15) were diagnosed with hypertension. The differences in the occurrence of endpoint events during postoperative follow-up were similar between the two groups (P>0.05). Conclusion: In experienced centers, long-term prognosis of patients with aortic coarctation combined with descending aortic aneurysm is satisfactory post surgical intervention.

OBJECTIVE: To explore the feasibility and clinical effect of Stand-alone oblique lateral interbody fusion (OLIF) in the treatment of lumbar intervertebral disc degeneration with Modic changes and endplate sclerosis. METHODS: A retrospective analysis was performed on 16 cases with lumbar intervertebral disc degeneration with Modic changes and endplate sclerosis admitted to three medical centers from January 2015 to December 2018. There were 6 males and 10 females, the age ranged from 45 to 67 years old with an average of (55.48±8.07) years old, the medical history ranged from 36 to 240 months with an average of (82.40±47.68) months. The lesion sites included L_2,3 in 2 cases, L_3,4 in 5 cases, and L_4,5 in 9 cases. All patients presented with chronic low back pain with lower limb neurological symptoms in 3 cases. All patients were treated by Stand-alone oblique lateral lumbar interbody fusion. Clinical and radiological findings and complications were observed. RESULTS: There was no vascular injury, endplate injury and vertebral fracture during the operation. The mean incision length, operation time, and intraoperative blood loss were(4.06±0.42) cm, (45.12±5.43) min, (33.40±7.29) ml, respectively. The mean visual analogue scale (VAS) of the incision pain was (1.14±0.47) at 72 hours after operation. There was no incision skin necrosis, poor incision healing or infection in patients. Sympathetic chain injury occurred in 1 case, anterolateral pain and numbness of the left thigh in 2 cases, and weakness of the left iliopsoas muscle in 1 case, all of which were transient injuries with a complication rate of 25%(4/16). All 16 patients were followed up from 12 to 36 months with an average of (20.80±5.46) months. The intervertebral space height was significantly recovered after operation, with slight lost during the follow-up. Coronal and sagittal balance of the lumbar spine showed good improvement at the final follow-up. There was no obvious subsidence or displacement of the cage, and the interbody fusion was obtained. At the final follow-up, Japanese Orthopaedic Association(JOA) score and Oswestry disability index(ODI) were significantly improved. CONCLUSION As long as the selection of case is strict enough and the preoperative examination is sufficients, the use of Stand-alone OLIF in the treatment of lumbar intervertebral disc degeneration with Modic changes and endplate sclerosis has a good results, with obvious clinical advantages and is a better surgical choice.
