ABSTRACT

Objective:To quantitatively evaluate myocardial microcirculation perfusion changes after percutaneous intracardiac septal radiofrequency ablation (PIMSRA, Liwen procedure) in patients with obstructive hypertrophic cardiomyopathy (HOCM) using myocardial contrast echocardiography (MCE) and to further establish the effect of the procedure and predict the long-term prognosis of patients.Methods:A total of 45 patients with HOCM treated by the Liwen procedure in the First Affiliated Hospital of Air Force Medical University (Xijing Hospital) from July 2019 to June 2020 were included. MCE was performed before and 6 months after surgery, respectively. Time-intensity perfusion curve analysis was performed using QLab 10.8 offline software to obtain quantitative parameters of myocardial microcirculation perfusion including myocardial blood volume (A value), myocardial blood flow velocity (β value), and myocardial blood flow (A×β value), then the changes in parameters before and after the procedure were compared.Results:After the Liwen procedure, the mean septal thickness and mean left ventricular free wall thickness were significantly reduced, accompanied by a significant reduction in the left ventricular outflow tract pressure gradient (LVOT-PG) and mitral regurgitation length, and a significant improvement in mitral systolic antegrade motion (SAM) (all P<0.001). In addition, the left ventricular ejection fraction (LVEF) did not deteriorate significantly ( P=0.560) and the E/e′ ratio decreased after the procedure ( P=0.015). Besides, the A values of both the ventricular septum and the left ventricular free wall were not significantly changed compared to those before procedure ( P>0.05), whereas the β values and A×β values were obviously increased ( P<0.05). Conclusions:Myocardial blood velocity and myocardial blood flow in the septum and left ventricular free wall were significantly increased in patients with HOCM after the Liwen procedure, suggesting a significant improvement in myocardial microcirculation perfusion. MCE provides a non-invasive quantitative evaluation parameters of myocardial microcirculation perfusion for the Liwen procedure for the treatment of HOCM.

ABSTRACT

Objective:To study whether Tanreqing injection (TRQ) can alleviate the body injury in the process of infection by inhibiting the production and release of <italic>α</italic>-hemolysin of <italic>Staphylococcus aureus</italic> under sub-minimal inhibitory concentration, and to provide experimental basis for better guidance of clinical medication. Method:The effects of TRQ on the minimum inhibitory concentration (MIC) and bacterial growth of <italic>S.aureus</italic> were determined firstly by microplate method and time-growth curve. The different sub-minimal inhibitory concentrations of TRQ were co-cultured with bacteria or bacterial supernatants, and then co-incubated with defibrillated rabbit blood to detect the inhibitory and neutralizing effects of TRQ on <italic>S.aureus</italic> <italic>α</italic>-hemolysin. Cell counting kit-8 (CCK-8) cell viability assay was used to detect the protective effect of TRQ on <italic>S. aureus</italic>-mediated damage to human alveolar epithelial cells (A549). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the effect of sub-minimal inhibitory concentration of TRQ on the mRNA expression of <italic>S.aureus</italic> <italic>α</italic>-hemolysin regulatory genes hla and agrA. Result:The MIC of TRQ to <italic>S.aureus </italic>was 1/8 of the stock solution, and the sub-minimal inhibitory concentration (1/64MIC-1/16MIC) TRQ used in this study did not affect the growth of bacteria. 1/64MIC-1/16 MIC TRQ had the effect of inhibiting and neutralizing the hemolytic activity of <italic>α</italic>-hemolysin, with a protective effect on <italic>S.aureus</italic> supernatant-mediated A549 cell damage, and its inhibitory effect on <italic>α</italic>-hemolysin was closely related to the inhibition of hla and agrA mRNA expression. Conclusion:The sub-minimal inhibitory concentration TRQ can inhibit and neutralize the hemolytic activity of <italic>α</italic>-hemolysin of <italic>S.aureus</italic>, with a protective effect on A549 cell damage mediated by <italic>S.aureus</italic> infection, and its mechanism of inhibiting <italic>α</italic>-hemolysin is closely related to the interference with agr regulatory system.

ABSTRACT

Purpose@#The purpose of this study was to determine if somatic mutations are associated with clinical and pathologic outcomes in patients with borderline resectable pancreatic cancer (BRPC) or locally advanced pancreatic cancer (LAPC) who were treated with neoadjuvant chemotherapy and stereotactic body radiotherapy (SBRT). @*Materials and Methods@#Patients treated with neoadjuvant chemotherapy and SBRT followed by surgical resection from August 2016 to January 2019 and who underwent next generation sequencing of their primary tumor were included in the study. Next-generation sequencing was performed either in-house with a Solid Tumor Panel or with FoundationOne CDx. Univariate (UVA) and multivariable analyses (MVA) were performed to determine associations between somatic mutations and pathologic and clinical outcomes. @*Results@#Thirty-five patients were included in the study. Chemotherapy consisted of modified FOLFIRINOX, gemcitabine and nab-paclitaxel, or gemcitabine and capecitabine. Patients were treated with SBRT in 33 Gy in 5 fractions. On UVA and MVA, tumors with KRAS G12V mutation demonstrated better pathologic tumor regression grade (TRG) to neoadjuvant therapy when compared to tumors with other KRAS mutations (odds ratio = 0.087; 95% confidence interval [CI], 0.009–0.860; p = 0.036). On UVA and MVA, mutations in NOTCH1/2 were associated with worse overall survival (hazard ratio [HR] = 4.15; 95% CI, 1.57–10.95; p = 0.004) and progression-free survival (HR = 3.61; 95% CI, 1.41–9.28; p = 0.008). On UVA, only mutations in NOTCH1/2 were associated with inferior distant metastasis-free survival (HR = 3.38; 95% CI, 1.25–9.16; p = 0.017). @*Conclusion@# In BRPC and LAPC, the KRAS G12V mutation was associated with better TRG following chemotherapy and SBRT. Additionally, NOTCH1/2 mutations were associated with worse overall survival, distant metastasis-free survival, and progression-free survival.

ABSTRACT

Objective:To investigate the feasibility of ultrasound-guided percutaneous endomyocardial septal cryoablation of in vitro porcine hearts and to compare its effect with the percutaneous endomyocardial radiofrequency ablation.Methods:Experiment 1: Six in vitro porcine hearts were divided into 1 min ( n=2), 3 min ( n=2) and 5 min ( n=2) groups according to the cryoablation time, and all were subjected to ultrasound-guided percutaneous intra-myocardial septal cryoablation at 100% power respectively. After cryoablation, ultrasound images, the size of the solid dissection of the ice ball, and the size of the necrotic area after melting of the frozen ice ball were measured. Experiment 2: The in vitro porcine hearts were divided into cryoablation group ( n=3) and radiofrequency ablation group ( n=3), and ultrasound-guided percutaneous endomyocardial septal cryoablation and radiofrequency ablation were performed with 100% cryo power and 40 W radiofrequency power, and the extent of complete necrotic area and incomplete necrotic area were compared between the two ablation methods after 1 min. Results:Experiment 1: In the 1 min cryoablation time group ( n=2), the short diameter of the puck measured by ultrasound was (8.00±0.84)mm, the short diameter of the puck measured by solid was (8.38±1.19)mm, and the short diameter of the necrotic zone measured by solid was (8.35±0.83)mm; in the 3 min group ( n=2), the short diameter of the puck measured by ultrasound was (19.4±0.28)mm, and the short diameter of the puck measured by solid was (19.03±0.33)mm, solid measurement of the short diameter of the necrotic zone was (19.16±0.25)mm; in the 5 min group ( n=2), the short diameter of the puck measured under ultrasound was (26.4±2.54)mm, solid measurement of the short diameter of the puck was (26.01±0.24)mm, and solid measurement of the short diameter of the necrotic zone was (24.82±0.25)mm. Randomized blocks analysis of variance was performed on this data and the difference of block Factor b (freezing time: 1 min, 3 min, 5 min) among the three groups was statistically significant( F=505.884, P<0.001). The SNK- q test showed that all three groups differed from each other(all P<0.05). The analysis results for the treatment factors K (measurement modality-ultrasound image measurements, solid anatomical measurements of the puck, and measurements of the necrotic area after melting of the frozen puck) was not statistically significant ( F=0.470, P=0.635). Experiment 2: In the RF ablation group ( n=3), the ratio of incomplete necrotic zone to the radius of the RF ablation area was 0.64±0.01; in the cryoablation group ( n=3), the ratio of incomplete necrotic zone to the radius of the ablation area was 0.26±0.02. The difference was statistically significant( P=0.002) and it can be considered that the incomplete necrotic zone of cryoablation was smaller than that of RF ablation. Conclusions:Percutameous intramyocardial septal cryoablation is controllable in scope, ultrasound image evaluation of ablation area is more accurate and incomplete necrosis area is small, which may have potential applications in cardiac ablation.

And 40 healthy controls matched with depression patients in age, gender and education level were collected as control group (HC group). The levels of eight inflammatory cytokines in Th17 immunoregulatory system (five pro-inflammatory cytokines: IL-1β, IL-6, IL-17A, IL-21, IL-23; three anti-inflammatory cytokines: TGF-β1, IL-10, and IL-27) were measured by enzyme-linked immunosorbent assay (ELISA). Hamilton depression scale-24 (HAMD-24) was used to evaluate the severity of depressive symptoms. Data analyses were performed with SPSS 23.0.Two independent samples t-test, one-way ANOVA, Mann Whitney U test and Kruskal Wallis H test were used for comparison between groups. Results:(1) Comparison of FED group, RMDD group and HC group showed that the levels of pro-inflammatory cytokines IL-1β (5.321(1.317, 21.287)ng/L, 11.277(4.315, 26.167) ng/L, 8.126(1.179, 9.287) ng/L), IL-6(7.787(2.077, 16.778) ng/L, 5.290(2.364.14.475) ng/L, 4.389(1.453, 4.491) ng/L), IL-21 (6.777(6.293, 9.198) ng/L, 7.261(6.293, 25.058)ng/L, 5.097(3.033, 6.507) ng/L) and anti-inflammatory cytokines TGF-β1 (59.098(13.491, 125.368) ng/L, 46.230(18.852, 122.559) ng/L, 25.292(2.716, 31.874) ng/L), IL-10 (226.930(105.117, 449.444) ng/L, 193.929(109.014, 468.269) ng/L, 131.429(77.587, 157.497) ng/L) and IL-27 (0.968(0.651, 1.879)ng/L, 1.859(0.690, 6.221) ng/L, 0.865(0.679, 1.287)ng/L) in plasma were statistically different( H=7.219, 9.482, 18.989, 16.166, 11.511, 6.262, all P<0.05), while the levels of pro-inflammatory cytokines IL-17A (2.175(1.031, 7.975)ng/L, 3.576(1.896, 11.611)ng/L, 3.807(1.301, 4.710)ng/L)and IL-23 (15.708(2.898, 114.175) ng/L, 26.893(9.282, 58.592) ng/L, 17.041(5.027, 23.613)ng/L) were not statistically significant ( H=2.179, 4.305, both P>0.05). Further pairwise comparisons showed that the levels of pro-inflammatory cytokines IL-6, IL-21 and anti-inflammatory cytokines TGF-β1 and IL-10 in plasma of FED group were higher than those of HC group, and the differences were statistically significant (all P<0.05). The levels of pro-inflammatory cytokines IL-1β, IL-6, IL-21 and anti-inflammatory cytokines TGF-β1, IL-10, IL-27 in RMDD group were higher than those in HC group, and the differences were statistically significant (all P<0.05). There were no significant differences in the eight inflammatory cytokines between FED group and RMDD group (all P>0.05). (2) Spearman correlation analysis showed that IL-1β was positively correlated with total score of HAMD-24 ( r=0.286, P<0.05). IL-6 was positively correlated with total score of HAMD-24 and factor score of anxiety or somatization ( r=0.390, 0.291, both P<0.05). TGF-β1 was negatively correlated with total score of HAMD-24 and factor scores of anxiety or somatization and cognitive impairment ( r=-4.200, -0.321, - 0.361, all P<0.05). IL-21 was positively correlated with factor score of sleep ( r=0.319, P<0.05); IL-10 was negatively correlated with total score of HAMD-24 and factor score of cognitive impairment ( r=-0.306, - 0.270, both P<0.05). There was no significant correlation between other inflammatory cytokines and total score of HAMD-24 and seven factor scores (all P>0.05). Conclusion:There is an imbalance in pro-and anti-inflammatory cytokines of Th17 immunoregulatory system in patients with depression, which is more obvious in recurrent episodes patients.The level of immune activation of Th17 immunoregulatory system may be associated with the severity of clinical symptoms, in which the inflammatory cytokine IL-6 may be a biomarker of major depressive disorder; TGF-β1 and IL-21 may be associated with depressive cognitive impairment and sleep.

ABSTRACT

Objective:To explore the relationship between somatic symptoms of major depressive disorder(MDD)and cortisol(COR) rhythm, C-reactive protein(CRP) and other immune-metabolism-related indicators, and understand its mechanism from the perspective of endocrine and immune regulation.Methods:A case-control study was conducted in hospitalized patients with MDD who met DSM-5 diagnostic criteria.According to the Patient Health Questionnaire (PHQ-15), PHQ-15 ≥10 were classified as the somatic major depressive disorder group(S-MDD group) and 73 patients were enrolled.PHQ-15 <5 was classified as the non-somatic depressive disorder group (NS-MDD group) and 70 patients were enrolled.Plasma cortisol (COR8, COR16 and COR24) levels were measured at 8∶00, 16∶00 and 24∶00 on the same day, plasma CRP and interleukin-6 (IL-6) level, serum uric acid (UA), blood glucose (GLU), blood lipid (TC, TG, HDL, LDL) level were detected at 8∶00.Independent sample t test, non-parametric test, chi-square test, repeated ANOVA, covariance analysis, and multivariate Logistic regression were used for statistical analysis. Results:①Time effect, grouping effect and the interaction effect of the time and grouping in the level of COR were statistically significant ( P<0.05). Covariance analysis excluded age as an influential factor, COR16, AUC(total cortisol output/area under the curve, AUC) and COR8-16 in S-MDD group ((90.50±40.57)μg/L, (1 425.12±564.78), (-6.43±5.76))were higher than those in NS-MDD group((68.74±31.51)μg/L, (1 251.57±456.61), (-8.77±5.48)), and the difference was statistically significant ( F=8.971, 4.320, 8.731, P<0.05). ②CRP in S-MDD group ((1.41±1.06)mg/L) were higher than that in NS-MDD group((0.61±0.53)mg/L), and the difference was statistically significant ( F=25.436, P<0.05). The proportion of patients with higher CRP level(CRP≥1 mg/L) in S-MDD group(58%) was higher than that in NS-MDD group(23%), and the difference was statistically significant(χ 2=17.824, P<0.01). ③Multivariate logistic regression analysis found that CRP ( OR=4.953, 95% CI: 2.407-10.193), COR8-16 ( OR=3.451, 95% CI: 1.380-8.633) were main risk factors of somatic symptoms of MDD ( P<0.05). Conclusion:Cortisol rhythm disturbance and high CRP level may be the biological basis of somatic symptoms in patients with MDD.

ABSTRACT

OBJECTIVE: To retrospectively analyze the clinical characteristics of 5 cases of occupational asbestos-induced pleural mesothelioma. METHODS: The clinical features and occupational diagnostic data of 5 patients with pleural mesothelioma caused by occupational asbestos exposure were collected. The occupational history, the occupational hazard exposure history, the length of latency, the clinical features, chest computed tomography(CT) and immunohistochemical staining examination of these 5 patients were analyzed. RESULTS: The median of occupational asbestos exposure length was 8 years and the median of latent period was 30 years in these 5 patients. One patient had been diagnosed as occupational asbestos lung. Typical chest CT findings of asbestos-induced pleural mesothelioma were one-sided pleural effusion, pleural nodules and enlarged mediastinal lymph nodes. The clinical symptoms were mainly chest pain, cheat tightness, and fatigue. Erythrocyte sedimentation rate increased in 3 cases. According to immunohistochemical findings, 4 patients showed that melanocortin, calretinin, cytokeratin 5/6, and cytokeratin 7 were positive, and 3 patients showed that wilms′ tumor nuclear protein were positive. Examination of lung function in 4 patients showed restrictive ventilation dysfunction. CONCLUSION: Most patients with pleura mesothelioma showed insignificant symptoms at early stage. The occupational health surveillance and chest CT examination of occupational asbestos-exposed workers should be strengthened, and early diagnosis should be made as soon as possible to win surgical opportunities.

ABSTRACT

OBJECTIVE: To analyze the clinical characteristics and diagnosis of silicosis with pulmonary tuberculosis and pulmonary aspergillosis. METHODS: The clinical data of a case of silicosis combined with pulmonary tuberculosis and aspergillosis was analyzed retrospectively. RESULTS: The clinical symptoms of this patient were chest tightness, suffocation, cough, expectoration and hemoptysis. The patient was diagnosed as tuberculosis in the local hospital in 2015. Two previous sputum smears of the patient were positive for mycobacterium tuberculosis. Both qualitative analysis of blood tubercle bacilli and sputum smear examination of acid-fast bacilli were negative. Chest computed tomography(CT) showed right lung pneumoconiosis with large shadow, left lower lobe of lung with uneven density and flake shadow, low density necrotic foci, a cavity with smooth wall. Sputum fungal culture: Aspergillus fumigatus(+++); bronchoscopic lung biopsy showed: Aspergillus pneumoniae. CONCLUSION: Low immunity, malnutrition and long-term use of antibiotics and hormones are the high risk factors of pulmonary aspergillosis. It is helpful to combine laboratory examination, patients′ clinical manifestations and chest CT characteristics, and to analyze the condition comprehensively for the early diagnosis of silicosis with pulmonary aspergillosis.

ABSTRACT

OBJECTIVE@#To explore the clinical characteristics and outcomes of adult critically ill patients with COVID-19 and identify the risk factors correlated with in-hospital deaths.@*METHODS@#This study was conducted among 20 confirmed adult cases of COVID-19 in the Intensive Care Unit (ICU) of Honghu People's Hospital in Jingzhou City, Hubei Province. According to the final outcome, the patients were divided into survivor group and death group with 10 patients each. The demographic data, clinical manifestations and signs, laboratory findings, treatment measures and clinical outcomes were obtained from electronic medical records to compare the clinical characteristics and outcomes between the two groups. Univariate logistic analysis was used to analyze the risk factors associated with in-hospital death.@*RESULTS@#The mean age of patients with confirmed COVID-19 was 70 ± 12 years, and 40% of them were male. The patients were admitted to ICU 11 ± 9 days after symptom onset. The most common symptoms on admission were cough (19 cases), fatigue or myalgia (18 cases), fever (17 cases) and dyspnea (16 cases). Eleven (55%) of the patients had underlying diseases, among which hypertension was the most common (11 cases), followed by cardiovascular disease (4 cases) and diabetes (3 cases). Six (30%) of the patients received invasive mechanical ventilation and continued renal replacement therapy but eventually died. Acute cardiac injury was the most common complication (19 cases). Half of the patients died between the 2nd and 19th day after ICU admission. Compared with dead patients, the surviving patients had a lower average body weight (61.70±2.36 68.60±7.15 kg, =0.01) and a higher Glasgow Coma Index (14.69 ± 0.70 12.70 ± 2.45, =0.03), and were less likely to develop shock (2 10, =0.001) or acute respiratory distress syndrome (2 10, =0.001).@*CONCLUSIONS@#Critically ill patients with COVID-19 are generally older. A higher body weight and a lower lymphocyte count are potentially associated with a greater likeliness of fatality in ICU patients with COVID-19.

ABSTRACT

Objective::To explore the feasibility of the rapid identification system(MALDI-Biotyper System) of microorganisms for rapid identification of Pseudomonas aeruginosa and clinical isolation of Staphylococcus aureus. Method::Identification quality control and clinical isolation were conducted for drug resistance of S. aureus by microbial rapid identification system and broth dilution method. The scores of microbial rapid identification system were compared with the MIC value of broth dilution method. The drug resistance of P. aeruginosa was simultaneously identified to determine the accuracy and applicability of the rapid identification system of microorganisms. Result::The scores of the microbial rapid identification system showed that the score of sensitive quality control strain S. aureus was higher than 2.000, and the that of resistant strain of methicillin-resistant S. aureus(methicillin-resistant S. aureus, MRSA)was between 1.700 and 2.000.The score of clinically isolated S. aureus was between 1.700 and 2.000, which suggested the drug resistance and was consistent with the MIC value of the broth dilution method. At the same time, the systemic identification value of the P. aeruginosa, which is independent of the quality control sensitive strain, was greater than 2.000, showing sensitivity and it was a sensitive strain itself, which was consistent with the results. Conclusion::The microbial rapid identification system scoring method can be used for the rapid identification of the drug resistance of S. aureus and P. aeruginosa.

ABSTRACT

OBJECTIVE@#To investigate the protective effect of quercetin against lipopolysaccharide (LPS)- induced acute kidney injury (AKI) in mice and explore its mechanism.@*METHODS@#Forty male BALB/c mice were randomly divided into control group (with saline treatment), 15 mg/kg LPS group, and quercetin-treated groups with intragastric quercetin treatment (once daily for 3 consecutive days) at low (25 mg/kg) and high (50 mg/kg) dose prior to 15 mg/kg LPS injection. LPS was administered by intraperitoneally injection 1 after the last gavage of quercetin. The mice were sacrificed 24 h after LPS injection for analysis of kidney pathologies, blood urea nitrogen (BUN) and creatinine levels; serum levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β) and IL-6 were detected by ELISA, and the expressions of Toll-like receptor-4 (TLR4), MyD88, TRAF-6 and NF-κBp65 in the kidney were detected by Western blotting.@*RESULTS@#Quercetin significantly lessened renal pathologies, lowered BUN and creatinine levels ( < 0.05) and inhibited TNF-α, IL-1β, and IL-6 production in mice with LPS-induced AKI ( < 0.05). Pretreatment with quercetin also significantly inhibited TLR4, MyD88, and TRAF-6 expressions and NF-κBp65 activation in the kidneys of the rats with LPS challenge ( < 0.05).@*CONCLUSIONS@#Quercetin pretreatment can protect mice against LPSinduced AKI by inhibiting TLR4/NF-κB signaling pathway.

ABSTRACT

Objective: To explore effect of modified Guifu Dihuang Wan (Wenshen Huoxue Fang) on life quality in patients with coronary hear disease (CHD) after percutaneous coronary intervention (PCI) and evaluate the safety of its clinical use. Method: The 147 postoperative patients with PCI in Chongqing Traditional Chinese Medicine Hospital cardiology outpatient and the inpatient departments between June 2017 to May 2018 were selected and randomly divided into the treatment group and control group by random even and odd number. The patients in control group took the basic treatment (western medicine), and the patients in the treatment group additionally received modified Guifu Dihuang Wan based on the treatment in control group, with a course of 4 weeks in both groups. Minnesota Living with Heart Failure Questionnaire (MLHFQ) total score, 6 minutes walk test (6 mWT), Seattle Angina Scale (SAQ) score, and traditional Chinese medicine(TCM) syndrome score were recorded and compared between two groups before and after treatment; their cardiac function was evaluated and adverse reactions were observed to assess the drug safety and quality of life after PCI. Result: The MLHFQ scores in treatment group after treatment were significantly lower than those before treatment and those in control groups after treatment (PPPPPConclusion: On the basis of conventional western medicine therapy, the modified Guifu Dihuang Wan can effectively improve the physical strength, mood, TCM symptoms, relieve angina pectoris, and enhance cardiac function with no adverse reactions in PCI postoperative patients. It can achieve the purpose of improving quality of life in postoperative patients, worthy of promotion.

ABSTRACT

Gentianae Radix et Rhizoma has a long history of medication,and was recorded in Shennong Bencaojing. Through the study of herbal medicine of Gentianae Radix et Rhizoma,we reviewed and analyzed previous herbal records,studied its basic,origin and processing methods, and provided the basis for further development and utilization of Gentianae Radix et Rhizoma. Through the analysis of ancient herbal researches and drawings,we knew that the ancient resources of this medicine were basically consistent with Gentiana scabra and G. manshurica. The Latin name of the original plant of gentian medicinal herbs set forth in the modern literature was analyzed for the first time. The commodities of this medicine were divided into Guanlongdan and Dianlongdan. Guanlongdan was produced in Northeast China, and consisted of G. scabra,G. manshurica,and G. triflora. Dianlongdan was G. rigescens and grew in Yunnan province. Due to various reasons, such as historical changes, genuine producing areas of medicinal materials gradually changed from Jiangsu and Zhejiang to Northeast China. The processing methods of Gentianae Radix et Rhizoma included preparing with wine, preparing with licorice juice and preparing with ginger juice. The purpose of these processing methods is to suppress its nature of bitter and cold. Among those processing methods,preparing with wine has the longest history, and can promote the dissolution of the active ingredients of gentian,thus is a better method of processing. This study provides the basis for radical reform, resource development, correct use, and determination of genuine producing area and processing methods for Gentianae Radix et Rhizoma.

ABSTRACT

Objective: To explore the situation of interpersonal adaption and its relation to extroversion and self-control in college students. Methods: Totally 3125 college students (1497 males, 1628 females; age from 16 to24 years) were assessed with the interpersonal adaption dimension from China College Student Adjustment Scale (CCSAS), Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) and Self-Control Scale (SCS). Results: The average score of interpersonal adaption was (33. 3 ± 3. 6). Regression analysis showed that extraversion and self-control positively predicted interpersonal adaption (β = 0. 25, 0. 08), interaction of extraversion and selfcontrol negatively predicted interpersonal adaption significantly (β =-0. 08). In the introvert group, the interpersonal adaption scores were higher in students with higher self-control scores than in those with lower self-control scores (P < 0. 001). Conclusion: It suggests that college students have good interpersonal adaptation. Self-control may buffer the negative effect of low extraversion on interpersonal adaption.

ABSTRACT

Objective To investigate the current state of psychological distress of lymphoma patients'caregivers, and analyze its influencing factors. Methods From October 2017 to February 2018, 96 pairs (patients and their caregivers) from the department of lymphoma were enrolled. Distress Thermometer and self-designed general scale were adopted to conduct survey. Results The psychological distress score of lymphoma caregivers was as high as (4.76 ± 2.28) points, which was significantly higher than the patient's score (3.81±2.33) points, the difference was statistically significant (t=4.070,P<0.05 ). Different ages, economic status, and patient's disease of caregivers had different psychological distress, and the difference was statistically significant (P<0.05). Meta-linear regression analysis showed that age and patient psychological distress were the main influencing factors of psychological distress of lymphoma patients'caregivers, which could explain the variability of 32.7%(P<0.05). Conclusions The psychological distress of lymphoma patients'caregiver is at a moderate level, which is affected by their age and psychological distress of the patients. It suggests that clinical medical staff should pay attention to the psychological distress of patients and strengthen the psychological support of caregivers to better promote patient care.

ABSTRACT

OBJECTIVE@#To investigate the effects of Notch signal on hypoxic induction factor (HIF-1α) and autophagy-associated genes Beclin1, LC3I, LC3II in oxygen-glucose deprivation (OGD) induced myocardial cell injury.@*METHODS@#The OGD model was established using hypoxic culture box and hypoglycemic DMEM medium. The cells were divided into normal control group, OGD group, OGD + NC siRNA group, OGD + Notch1 siRNA group and OGD + HIF-1α siRNA group. Western blot was used to detect the interference effects of HIF-1α siRNA and Notch1 siRNA. The effects of Notch1 siRNA and HIF-1α siRNA on the activity of myocardial cells in OGD model were detected by the CCK-8 assay. The effects of Notch1 siRNA and HIF-1α siRNA on autophage-associated genes Beclin1, LC3I and LC3II expression were detected by Western blot.@*RESULTS@#The results of Western blot showed that HIF-1α siRNA could effectively knock down the expression of HIF-1α in myocardial cells in OGD model, and Notch1 siRNA could effectively knock down the expression of Notch1 and HIF-1α in myocardial cells in OGD model. The result of CCK-8 assay showed that Notch1 siRNA and HIF-1α siRNA reduced the activity of myocardial cells in OGD model, and there was no statistical difference between the two groups. Western blot results showed that Notch1 siRNA and HIF-1α siRNA could reduce the expressions of the autophagy-associated genes Beclin1, LC3I and LC3II, and reduce the ratio of LC3II to LC3I at mRNA level.@*CONCLUSION@#Notch1 plays a role in myocardial protection by regulating the expression of HIF-1α to regulate the autophagy in OGD model cells.
