Objective To explore the effects of astaxanthin on pressure injury wounds.Methods In vitro experiment:Fibroblasts were treated with different concentrations of astaxanthin and their proliferation activity was detected by CCK-8 assay.Subsequently,fibroblasts were induced by hypoxia/reoxygenation,and the optimal concentration of astaxanthin was administered.Then the intracellular reactive oxygen species(ROS)level was detected by DHE fluorescent probes and the mRNA expression level of TNF-α,IL-1β,IL-6,IL-10,TGF-β was evaluated by RT qPCR.In vivo experiment:to construct a pressure injury model,two circular magnets were symmetrically adsorbed on both sides of the mouse skin for 5 hours everyday.Subsequently,equal amounts of physiological saline,low-dose astaxanthin(10 mg/kg),and high-dose astaxanthin(20 mg/kg)were administered by gavage in groups.Wound images were taken regularly.After 7-day treatment,wound healing rates were counted and wound tissues were collected for histopathological staining.Results In vitro,the fluorescence intensity of DHE in the astaxanthin groups were reduced dramatically.The relative mRNA expression level of TNF-α,IL-1β,IL-6 in the astaxanthin group declined,and the level of TGF-β and IL-10 mRNA increased significantly(P<0.05).In vivo,the wound healing rate and the level of TGF-β,IL-10 in high-dose astaxanthin group increased significantly.The ROS content and the level of TNF-α,IL-1β and IL-6 dropped markedly in astaxanthin groups(P<0.05).Conclusions Astaxanthin can significanlty alleviate oxidative stress,mitigate inflammation,thus exerting a protective effect on pressure injury wounds.

Objective:To compare the application value of Caprini thrombosis risk assessment scale and Shanghai venous thrombosis risk factor scale in predicting venous thromboembolism in hospitalized maternal patients.Methods:This was a case-control study. A total of 67 pregnant women complicated with venous thromboembolism in the Obstetrics Department of Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2010 to September 2021 were retrospectively analyzed. And 144 pregnant women without venous thromboembolism in the same period were selected. Two venous thrombosis risk assessment tools were used to evaluate the pregnant women, and the predictive effectiveness and accuracy of the two assessment tools were compared.Results:The effects of the two risk assessment tools for venous thrombosis were different before and after delivery with statistical difference ( Z=8.15, 5.97, both P<0.01), but the Shanghai venous thrombosis risk factor scale (83.9%, 67.3%) was superior to Caprini thrombosis risk assessment scale (52.1%, 45.0%) in the accuracy of prenatal and postnatal prediction. The area under receiver operating characteristic curve showed that the Shanghai venous thrombosis risk factor rating scale (0.863) was significantly superior to the Caprini thrombosis risk assessment scale (0.748) after delivery. Conclusions:The Shanghai venous thrombosis risk factor scale is more valuable than the Caprini thrombosis risk assessment scale in the early risk identification of venous thromboembolism in pregnant women.

Objective:The study aimed was to explore the safety and efficacy of neoadjuvant immunochemotherapy for non-small cell lung cancer (NSCLC).Methods:We retrospectively collected data of all patients who received neoadjuvant immunochemotherapy and chemotherapy for NSCLC followed by surgery in our unit between January 2019 to September 2021.Results:Forty-four patients were diagnosed with NSCLC in a stageⅠ(2 cases), ⅡA(7 cases), ⅡB(11 cases), ⅢA (15 cases), ⅢB (1 case). The average age was 63 years old(range 44-71 years old). Squamous cell carcinoma accounted for 65.91% of all patients. Central lung cancer accounted for the vast majority, with 39 patients (88.64%). There were 19 cases in the neoadjuvant immunochemotherapy group and 25 cases in the neoadjuvant chemotherapy group; the average interval between the end of neoadjuvant therapy and the day of operation was 34 days, including( 33.74±10.66 )days in the immunochemotherapy group and (33.88±11.9) days in the chemotherapy group, and there was no significant difference between the two groups. No grade 3 or more adverse events occurred in all patients. There were 13 cases (63.16%) reached PR (partial response)+ CR (complete response) according to the Response Evaluation Criteria in Solid Tumors (RECIST v. 1.1) in the neoadjuvant immunity group and 11 cases (44.00%) in the neoadjuvant chemotherapy group. There was no significant difference between the two groups. In the neoadjuvant immunochemotherapy group, 9 cases (47.37%) achieved down-staging, In the neoadjuvant chemotherapy group, 8 cases (32.00%) achieved down-staging, there was no significant difference between the two groups. Seven patients (36.84%) in neoadjuvant immunochemotherapy group showed pCR (pathologic complete remission), but there were no patients who reached pCR in the neoadjuvant chemotherapy group., the difference was statistically significant ( P=0.001). Four patients (21.05%) in the neoadjuvant immunochemotherapy group reached mPR (major pathologic response), 6 patients (24.00%) in the neoadjuvant chemotherapy group reached mPR, and the difference was no statistically significant( P= 0.817). Conclusion:The safety of neoadjuvant immunochemotherapy was satisfactory; Compared with neoadjuvant chemotherapy, neoadjuvant immunochemotherapy did not increase the preoperative grade 3 adverse events and prolong the waiting time before operation; neoadjuvant immunochemotherapy had obvious advantages in pCR, which provided the possibility for the cure of tumor.

Objective:In this study, we established a reliable surgical procedure of lung ischaemia-reperfusion(IR) injury in rats. The research progress of different lung IR injury models and application value was also discussed.Methods:Twenty-eight adult SD rats were randomly divided into SHAM group and lung IR injury group(IR group), 14 rats in each group. In IR group, rats underwent tracheotomy under general anesthesia and received mechanical ventilation. Chest was opened in supine position, and pulmonary hilum was blocked for 30 minutes then the occlusion was removed. Samples were harvested after reperfusion for 45minutes. Rats in SHAM group received surgery and exposure of the right pulmonary artery, and experienced the same amount of time before the chest closed. Arterial blood gas was extracted postoperatively. Gross view of the lungs and pathological changes were observed, and the dry/wet ratio(W/D) was determined. Protein level of pro-inflammatory factors, markers in oxidative stress pathway, and endothelial functional markers in lung were tested by western blot analysis.Results:In IR group, there was pink foamy secretion in the airway, and the lungs exhibited signs of edema and congestion. In IR group, the alveolitis score was significantly increased, the W/D ratio was also increased, p38MAPK and NF-κB signaling pathways were activated, and the expression of TNF-α was significantly increased, while the expression of eNOS was significantly decreased.Conclusion:Left hilum clamping and bilateral reperfusion injury in lung is a practical animal model, it is a simple, low-cost and repeatable animal model for further studies. No microsurgical instruments were required during the procedure. Lung IR injury is characterized by oxidative stress response, inflammatory response and endothelial cell dysfunction.

Purpose: Effective predictors of the response to neoadjuvant chemotherapy (NAC) are still insufficient. This study aimed to investigate the predictive value of serum lipid profiles for the response to NAC in breast cancer patients. Methods: A total of 533 breast cancer patients who had received NAC were retrospectively studied. The pretreatment of serum lipids, including total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and lipoprotein-α, and clinicopathological characteristics were collected to assess their predictive roles. Results: Breast cancer patients had significantly lower TC, TG, HDL-C, and LDL-C levels than normal individuals. Among these indicators, TG and LDL-C levels and HDL-C level increased and decreased significantly after NAC, respectively. In estrogen receptor (ER)-positive patients, increased LDL-C level was associated with better outcomes. Moreover, the receiver operating characteristic curve analyses suggested that TG and HDL-C levels at diagnosis can be used as predictors of the response to NAC only in the ER-positive subgroup.According to univariate analyses, patients with low TG level (< 1.155 mmol/L) or high HDL-C level (≥ 1.305 mmol/L) in the ER-positive subgroup had more favorable clinical responses than the other patients in the subgroup. Furthermore, according to multivariate analyses, a high HDL-C level (≥ 1.305 mmol/L, p = 0.007) was an independent predictor of NAC efficacy. Conclusion High HDL-C level (≥ 1.305 mmol/L) before NAC and increased LDL-C level after NAC were associated with the better treatment response in ER-positive breast cancer patients.These results are potentially considered beneficial in establishing treatment decisions.

Objective:To evaluate the effect of interstitial lung disease(ILD) on postoperative morbidity and mortality in pulmonary resection for lung cancer patients.Methods:We retrospectively analyzed 971 patients undergoing pulmonary operation from January 2010 to January 2018 in our hospital. Clinical data including age, sex, history of chronic obstructive pulmonary disease(COPD), smoking history, smoking index, American Society of Anesthesiologists(ASA) classification, forced expiratory volume in 1 s(FEV1) % predict, surgical procedure, video assisted thoracoscopic surgery(VATS) or not, intraoperative blood transfusion, anesthesia time, operation time/one-lung ventilation time, blood loss, histology, postoperative morbidity, 60-days mortality, onset of acute exacerbation of interstitial lung disease(AE-ILD), drainage, extubation time, and postoperative stay were collected and analyzed.Results:There were 80(8.2%) and 891(91.8%) patients in ILD and non-ILD group, respectively. AE-ILD occurred in 5 patients, with a 60-day mortality of 80%. A multivariate regression analysis identified that the sex( P=0.023), ILD( P=0.001), COPD( P=0.027) were independent risk factors for postoperative morbidity. ILD( P=0.023) and postoperative morbidity( P=0.001) were independent risk factors for 60-day mortality in multivariate analysis. Conclusion:Patients with ILD had a higher incidence of postoperative morbidity and 60-day mortality. Based on the obvious postoperative morbidity and mortality, special attention and management should be taken in ILD patients.

The mechanism of cell transplantation in repairing spinal cord injury mainly include replacing damaged neurons, protecting host neurons, preventing apoptosis, promoting axon regeneration and synapse formation, promoting myelination and secreting nutritional factors to improve microenvironment. A variety of cells have been used to repair spinal cord injury in animal models with certain effects, but the repair effect on complete injury is not obvious. Due to the difficulty in repairing spinal cord injury and the complexity of high-quality clinical studies, there lacks safe and effective comprehensive treatment method to maximize the improvement and recovery of patients' motor function. In order to summarize the research progress of cell therapy in the treatment of spinal cord injury and promote the in-depth study in this field, this article reviews various cell repair methods for spinal cord injury in aspects of their current status, safety and effectiveness and discusses the prospects of cell repair of spinal cord injury.
