RESUMO

Lupus nephritis (LN) is one of the most severe manifestations of systemic lupus erythematosus (SLE). The chronic graft versus host disease (cGVHD) mouse model is a well-established model of SLE. LC3-associated autophagy plays a critical role in extracellular particle clearance, including pathogens and apoptotic cells. Lupus Recipe (LR) is a Chinese herbal compound that has been proven to be effective in treating SLE. In the study, we investigated the protective effects of LR or LR combined with prednisone on cGVHD mouse model and LC3-associated autophagy in the kidney. The mice were subjected to six groups. The LR treatment group received LR at the dosage of 1.15 and 2.3 g/kg/day, respectively. The corticosteroid treatment group received prednisone at a dosage of 5 mg/kg/day. The combination treatment group received LR at a dosage of 2.3 g/kg/day, and prednisone at 2.5 mg/kg/day. LR treatment reduced proteinuria and serum triglyceride levels, as well as spleen weight. LR also alleviated pathologic damage and immunoglobulin G deposition in the kidney. LR combined with a low dose of prednisone significantly improved kidney function and decreased serum triglyceride, total cholesterol, and spleen weight. In addition, combination treatment relieved kidney injury more effectively than LR alone. Western blot revealed that LR treatment or LR combined with prednisone increased the LC3-associated autophagy protein of Rubicon and Nox2, as well as LC3I levels in the kidney tissues. In conclusion, LR inhibited the manifestation of cGVHD-induced LN, which may attribute to the increased levels of LC3-associated autophagy.

RESUMO

Objective: No study has reported the risk stratification of BMI and PNI in patients with locally advanced esophageal squamous cell carcinoma (ESCC) undergoing definitive chemoradiotherapy (dCRT). This study aimed to construct a risk stratification to guide the treatment of ESCC following dCRT. Methods: A total of 1,068 patients with locally advanced ESCC who received dCRT were retrospectively analyzed. The impacts of clinicopathological factors on overall survival (OS) and progression-free survival (PFS) were analyzed. Besides, the novel prognostic indices of pre-therapeutic nutritional index (PTNI) and prognostic index (PI) were developed. Results: The median follow-up period of OS and PFS were 22.9 and 17.4 months, respectively. The high body mass index (BMI) group had better 5-year OS and PFS (36.4 and 34.0%) than the low BMI group (18.8 and 17.2%). The high prognostic nutritional index (PNI) group also had better 5-year OS and PFS (33.4 and 30.9%) than the low PNI group (17.5 and 17.2%). Multivariate Cox regression analysis showed that BMI and PNI were independent prognostic factors for OS and PFS. Based on nutritional indices, patients were categorized into the low-risk (PTNI = 1), medium-risk (PTNI = 2), and high-risk (PTNI = 3) groups with 5-year OS rates of 38.5, 18.9, 17.5%, respectively (p < 0.001) and 5-year PFS rates of 35.8, 17.6, 16.8%, respectively (p < 0.001). Besides, we also constructed a prognostic index (PI) for OS and PFS which was calculated based on statistically significant factors for predicting OS and PFS. The results revealed that the high-risk group had worse OS and PFS than the low-risk group (p < 0.001). Finally, RCS analysis demonstrated a non-linear relationship between the PNI, BMI, and survival for patients with ESCC. The death hazard of PNI and BMI sharply decreased to 41.8 and 19.7. Conclusion: The decreased pre-therapeutic BMI and PNI levels were associated with a worse survival outcome. BMI and PNI are readily available and can be used to stratify risk factors for locally advanced ESCC patients undergoing dCRT. The novel risk stratification may help to evaluate patients' pre-therapeutic status and guide dCRT for locally advanced ESCC patients.

RESUMO

The purity of soy lecithin exerts significant impact on nanoliposome (NL) properties for food applications. In this study, three soy lecithin of different purity were used to prepare NL. LC-MS analysis confirmed soy lecithin of relatively low purify (50% and 70%) contains multiple natural phospholipids. NL produced by soy lecithin of middle purity (70%) is smaller and more stable than other counterparts. Ultimately, soy lecithin of 70% purity was selected to develop NL encapsulated crocetin (CR) as model payload and further coated by chitosan (CS). The structure characteristic, physicochemical properties, antioxidant activity and anti-inflammatory activity of crocetin nanoliposome (CR-NL) and chitosan coated crocetin nanoliposome (CS-CR-NL) were evaluated. NL encapsulation and CS coating significantly improve antioxidant and anti-inflammatory ability of CR, and prolong storage period of CR (p < 0.05). For food applications, soy lecithin of middle purity (70%) is cheaper and more appropriate than soy lecithin of high purity.

RESUMO

Background: Currently no study has examined the effects of probiotic administration on the symptoms of anxiety, depression, and mania, as well as their correlations with the biomarkers of oxidative stress in patients with bipolar disorder (BPD). The aim of this study is to determine the effects of probiotic supplementation on plasma oxidative stress-related biomarkers and different domains of clinical symptom in patients suffering from BPD. Methods: Eighty first-episode drug-naive patients with BPD were recruited. The subjects were randomized to receive psychotropic drugs supplementing with either probiotic or placebo and scheduled to evaluate with follow-ups for clinical symptom improvements and changes in the oxidative stress biomarkers. The Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, and Young Mania Rating Scale were used to assess the clinical symptomatology. The panel of plasma oxidative stress biomarkers were determined by ultra-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) at baseline and for 3 months of follow-up, i.e., at post-treatment month 1, 2, and 3. Results: After 3 months of intervention, decreased levels of plasma lysophosphatidylcholines (LPCs) were found in both placebo and probiotic groups. However, six other oxidative stress biomarkers (i.e., creatine, inosine, hypoxanthine, choline, uric acid, allantoic acid) increased in BPD patients after the two types of therapies. In addition, a positive correlation between changes of LPC (18:0) and YMRS scale was found in BPD patients and this association only existed in the probiotic group. Additionally, the mania symptom greatly alleviated (pretreatment-posttreatment, odds ratio = 0.09, 95%CI = 0.01, 0.64, p= 0.016) in patients who received probiotic supplements as compared with the placebo group. Conclusion: The changes in plasma biomarkers of oxidative stress in patients with BPD have a potential to be trait-like markers, and serve as prognostic indexes for bipolar patients. Daily intakes of probiotics have advantageous effects on BPD patients with certain clinical symptoms, especially manic symptoms. The treatment may be a promising adjunctive therapeutic strategy for BPD patients in manic episode.

RESUMO

BACKGROUND: Abnormalities of functional connectivity (FC) in certain brain regions are closely related to the pathophysiology of major depressive disorder (MDD). Findings are inconsistent with different presuppositions in regions of interest. Our research focused on voxel-wise brain-wide FC changes in patients with MDD in an unbiased manner. METHOD: We examined resting-state functional MRI in 23 patients with MDD and 26 healthy controls. Imaging data were analyzed by using global-brain FC (GFC) and used to explore the correlation of abnormal GFC values with clinical variables. RESULTS: Increased GFC values in the left medial superior frontal gyrus (SFGmed) and decreased GFC values in the right supplementary motor area (SMA) were observed in the patients with MDD compared with the controls. The decreased GFC values in the right SMA had a positive correlation with vitamin D and Hamilton Anxiety Scale (HAM-A) scores. CONCLUSION: Abnormal GFC in the hate circuit, particularly increased GFC in the left SFGmed and decreased GFC in the right SMA, appears to be a new sight for comprehending the pathological alterations in MDD.

RESUMO

L-theanine, originally found in green tea, elicits various physiological effects, such as promoting relaxation, improving concentration and learning ability, and providing antianxiety-like and antidepressant-like properties. This study aims to investigate the effects of L-theanine (2 mg/kg) on monoamine levels in an animal model of depression. The effect of l-theanine on the symptoms of depression was examined through the open-field test, sucrose preference test, and forced swim test. The monoamine neurotransmitters that involve serotonin (5-HT), norepinephrine (NE), and dopamine (DA) were measured in the limbic-cortical-striatal-pallidal-thalamic (LCSPT)-circuit related brain regions, including the prefrontal cortex (PFC), nucleus accumbens (NAC), striatum (ST), amygdala, and hippocampus (HIP). L-theanine ameliorated the depressive-like behaviors in the chronic unpredictable mild stress (CUMS) rat model. In the PFC, NAC, and HIP, L-theanine administration significantly increased the levels of 5-HT, NE, and DA. In the ST, the levels of 5-HT and DA were increased after the administration of L-theanine. However, in the HIP, only the level of DA significantly changed after the treatment of L-theanine. Taken together, these results indicated that L-theanine has possibly antidepressant-like effects in the CUMS rat model, which could be mediated by the monoamine neurotransmitters in the LCSPT-circuit related brain regions.

RESUMO

OBJECTIVE: To summarize the perioperative blood management strategies for joint arthroplasty. METHODS: The literature concerning preoperative, intraoperative, and postoperative blood management was reviewed and summarized. RESULTS: At present, a variety of blood management and conservation strategies are available. Preoperative strategies include iron supplementation, erythropoietin (EPO), and preoperative autologous donation (PAD). Intraoperative options include acute normovolemic hemodilution (ANH), antifibrinolytics, and the use of a tourniquet. Postoperative strategies include the use of reinfusion systems and guided transfusion protocols. Preoperatively, administration of either simple EPO or a combination of EPO and PAD can be efficacious in anemic patients. Intraoperatively, tourniquet use and tranexamic acid can effectively control bleeding. Postoperatively, appropriate transfusion indications can avoid unnecessary blood transfusions. CONCLUSION: Perioperative blood management strategies for joint arthroplasty should be integrated for the individual patient using a variety of ways to reduce perioperative blood loss and blood transfusion, and promote the rehabilitation of patients.

RESUMO

To investigate the influence of Anxin granules combined with tirofiban on acute myocardial infarction (AMI) Patients after elective percutaneous coronary intervention (PCI). One hundred and twenty AMI patients were randomly divided into treatment group and control group. The patients in the two groups were all given Tirofiban 30mins before PCI . The treatment group was added Anxin granules 30 mins before and after PCI. Tissue factor (TF) and von willebrand factor (vWF) were tested at 6 hours after operation. Syndromatology alteration of traditional Chinese medicine (TCM) and bleeding complications were observed at 4 weeks after operation. Both TF and vWF at 6 hours after operation of the treatment group was lower than the control group significantly (P < 0.01), while the condition of myocardial ischemia at 90 mins after operation of the treatment group was better than control group with significance. The syndromatology alteration of TCM especially spontaneous perspiration and hypodynamia of the treatment group were improved significantly compared to control group 4 weeks after operation. All patients in both groups had no bleeding complications and thrombopenia. The study suggests that Anxin granules combined with tirofiba can improve the clinical efficacy and the endothelial function of AMI patients after PCI with no increase in bleeding events.

RESUMO

OBJECTIVES: To explore the effects of progressive muscle relaxation (PMR) training on anxiety, depression and quality of life (QOL) of endometriosis patients under gonadotrophin-releasing hormone (GnRH) agonist therapy. STUDY DESIGN: This was a controlled, randomized, open-label study. One hundred consecutive Han Chinese endometriosis patients, aged 18-48 years, were randomly assigned to a PMR group (n=50) and a control group (n=50). In a study of 12 weeks' duration, both groups received one dose of depot leuprolide, 11.25mg IM. In addition to the GnRH agonist therapy, the PMR group received 12 weeks of PMR training. Anxiety level was measured using the state-trait anxiety inventory (STAI). Depression was assessed using subscale D of the hospital anxiety and depression scale (HADS-D). Health-related QOL was measured with SF-36 instrument. The patients were evaluated with STAI, HADS-D and SF-36 before and after the PMR intervention. RESULTS: The control group and the PMR group were comparable at baseline. After 12 weeks of intervention, both groups showed significant improvement in overall QOL (P<0.05). The PMR group, but not the control group, showed significant improvement in state anxiety, trait anxiety and depression after intervention (P<0.05). Moreover, the PMR group showed significant improvement in all QOL domains after intervention; by contrast, the control group showed significant improvement in all physical health domains and only two mental health domains after intervention. Between-group comparisons of the improvement in scores after intervention showed that the PMR group had significantly better improvement in the scores of anxiety, depression and overall/domain QOL than the control group (P<0.05). Repeated measures ANOVA revealed that both PMR intervention and time had significant individual as well as interactive effects on state anxiety, trait anxiety depression and overall QOL (P<0.05). CONCLUSIONS: This study suggests that PMR training is effective in improving anxiety, depression and QOL of endometriosis patients under GnRH agonist therapy. This is the first study to explore the effects of psychosomatic therapy on emotional status and QOL of endometriosis patients, and may serve as an important reference for future psychosomatic interventions on endometriosis.
