The effect of Radix isatidis polysaccharide(IRPS)on TLR3/TRIF innate immune path-way and type Ⅰ interferon secretion in 3D4/21/CD163 cells infected by porcine reproductive and re-spiratory syndrome virus(PRRSV)was tested by Western blot and ELISA;moreover,the effect of IRPS on the immunosuppression infected by PRRSV was further verified with the TLR3 agonist poly(I∶C).The results showed that the protein levels of TLR3,TRIF,IRF3,IRF7 and type Ⅰ in-terferon secretion were significantly decreased at 18,24 h of PRRSV infection,while IRPS signifi-cantly inhibited this process;poly(I∶C)alleviated the protein levels of TRIF,IRF3 and IRF7 as well as the phosphorylation levels of IRF3 and IRF7 infected by PRRSV;at the same time,IRPS is synergistic with poly(I∶C).The results indicate that IRPS is able to alleviate immunosuppression caused by PRRSV infection via the TLR3/TRIF pathway.

Purpose To investigate the clinicopathological and histological features of non-small cell lung cancer(NSCLC)patients with high expression of PD-L1 and positive driver muta-tion.Methods The clinical data of 141 patients with PD-L1 high expression and driver mutation-positive NSCLC were col-lected.Immunohistochemical methods,ARMS-PCR,and next-generation sequencing(NGS)were used to detect PD-L1 ex-pression and driver gene mutations.The clinicopathological fea-tures were analyzed and the related literatures were reviewed.Results There were 141 cases NSCLC patients with high ex-pression of PD-L1 in tumor cells,of which 57 cases were≥50％,＜60％;≥60％,＜70％in 18 cases;≥70％,＜80％in 35 cases;≥80％in 31 cases.Among 141 cases NSCLC patients with high PD-L1 expression,53 cases(37.6％)had driver gene mutations,including 4 cases BRAF 15 exon mutations,9 cases MET-associated mutations,17 cases EGFR-associated mutations,16 cases KRAS 2 exon mutations,4 cases EML4-ALK fusion mutations,and 3 cases other rare mu-tations.The high expression of PD-L1 and the occurrence of driver gene mutation were related to the gender,smoking history and pathological type of patients(P＜0.05).MET-related mu-tations and KRAS 2 exon mutations were more common in males than in females.All BRAF 15 exon mutations were female.The mean percentage of PD-L1 expression was highest in patients with MET mutation,KRAS 2 exon mutation,and 3 cases rare mutations.In 33 cases with BRAF 15 exon mutation,MET am-plification or mutation,EGFR-related mutation,and 3 cases oth-er rare mutations,PD-L1 was highly expressed in solid,glandu-lar,and micropapillary tumor cells.In 20 cases with KRAS 2 exon mutation and EML4-ALK fusion mutation,PD-L1 was highly expressed in solid nested tumor cells.Conclusion In NSCLC,high expression of PD-L1 and positive driver gene mu-tation are negatively correlated with the degree of tumor differen-tiation.In the poorly differentiated surgical specimens of lung adenocarcinoma,solid,micropapillary,or glandular tubular tumor tissues should be selected as far as possible for PD-L1 ex-pression and driver gene mutation detection.

ObjectiveThe internal transcribed spacer （ITS） 2 region of ribosomal gene， a DNA barcode， was employed to identify 12 medicinal Aconitum species and the genetic relationship among the species was analyzed. MethodA total of 30 samples of the 12 species were collected. The DNA was extracted with spin column plant genomic DNA kit and the universal primers of ITS2 sequence were used for polymerase chain reaction （PCR） amplification， followed by electrophoresis detection and bi-directional sequencing. The yielded sequences were aligned and spliced by CodonCode Aligner 17.0 and sequence variation was analyzed by MEGA 7.0. The secondary structure was predicted by ITS2 Database and the neighbor-joining （NJ） method was applied to generate the phylogenetic tree. ResultThe ITS2 sequences of the 12 species were 220-221 bp， with the average guanine and cytosine （GC） content of 64.09%， 140 variable sites， 137 informative sites， and 81 conservative sites. The intraspecific genetic distance （K2P） was smaller than the interspecific genetic distance. According to the secondary structures of ITS2 sequences and NJ cluster analysis， A. scaposum， A. sinomontanum， and A. barbatum had close genetic relationship， while the rest nine showed close kinship， particularly A. soongaricum and A. yinschanicum. ConclusionITS2 sequence is of great value for the molecular identification and genetic relationship determination of Aconitum， which provides a new method for the study of ethnomedicine.

Objective:To understand the incidence of mild cognitive impairment (MCI) of elderly patients with subjective memory impairment and analyze its influencing factors.Methods:A total of 322 patients with subjective memory impairment in elderly frail cognitive management clinic in General Hospital of Chinese PLA were selected by the convenient sampling method. According to the 2018 Diagnostic Criteria for Diagnosis and Treatment of Dementia and Cognitive Impairment in China, the subjects were divided into the MCI group and the non-MCI group. Demographic data, physiological factors, psychological factors, lifestyle and nutritional status of patients were collected using self-designed questionnaires. The Barthel Index Rating Scale was used to assess activity of daily living, 9-item Patient Health Questionnaire (PHQ-9) was used to assess depression and Generalized Anxiety Disorder Questionnaire (GAD-7) was used to to assess anxiety. The Pittsburgh Sleep Quality Index was used to assess sleep disturbances and Mini Nutritional Assessment Short Form (MNA-SF) was used to assess nutritional status. Univariate analysis and multivariate binary logistic regression analysis were used to explore the influencing factors of MCI in patients. Results:Among the 322 elderly patients with subjective memory impairment, 173 (53.73%) had MCI and 149 (46.27%) were non-MCI patients. Binomial Logistic regression analysis showed that reading habits, housework, social interaction, anxiety, age, depression, and sleep disturbance were the influencing factors of MCI in the elderly with subjective memory impairment ( P<0.05) . Conclusions:The incidence of MCI in elderly patients with subjective memory impairment is relatively high. The cognitive management clinic should comprehensively evaluate and analyze the influencing factors of such patients and assist patients to establish a healthy lifestyle according to their personal conditions, so as to improve their cognitive status.

Objective:To monitor the blood pressure in pediatric patients with coarctation of the aorta (CoA) before and 8 years after surgery, and explore the mechanism of elevated blood pressure in pediatric patients with repaired CoA.Methods:A cohort of 23 pediatric patients who underwent CoA repair between January 2010 and October 2010 in Guangzhou Women and Children's Medical Center was studied. And 20 age-, sex-match patients with isolated ventricular septal defect (VSD) who underwent surgery at the same time, 20 age-, sex-match health patients with normal echocardiographic findings were included in the study. Systolic blood pressure (SBP), diastolic blood pressure (DBP), arm-leg SBP gradient, right carotid intima-media thickness (CIMT), serum transforming growth factor-β1 (TGF-β1) were monitored at baseline(1 day before surgery) and 8-year follow-up (8 years after surgery).Results:There were no differences in SBP and DBP among patients with CoA, patients with VSD and health children at baseline ( P>0.05). But at 8-year follow-up, 2 patients with CoA exhibited hypertension. Not only that, patients with CoA had higher SBP than patients with VSD and health children at 8-year follow-up ( P<0.05). Patients with CoA had higher arm-leg SBP gradient than patients with VSD and health children at baseline ( P<0.01). But there were no differences in arm-leg SBP among patients with CoA, patients with VSD and health children at 8-year follow-up ( P>0.05). Patients with CoA had increased CIMT and higher serum levels of TGF-β1 at baseline and 8-year follow-up ( P<0.05). The preoperative levels of CIMT and serum TGF-β1 in the patients with CoA were highly positively correlated with their levels at 8-year follow-up, respectively ( P<0.01). There was a strong correlation between the levels of CIMT and serum TGF-β1 in patients with CoA, both preoperatively and postoperatively ( P<0.01). The preoperative and postoperative levels of CIMT and serum TGF-β1 in the patients with CoA were highly positively correlated with SBP at 8-year follow-up, respectively( P<0.05). Conclusion:Although surgery can successfully cure the anatomical " stenosis" , patients with CoA have elevated systolic blood pressure than normal people and patients with simple congenital heart disease (such as VSD). And some of the patients with CoA suffer from hypertension at long-term follow-up, even they are normotensive preoperatively. It may be related to vascular remodeling, in which TGF-β signaling pathway may be involved. Monitoring CIMT and TGF-β1 in patients with CoA preoperatively may be significative for prediction for the levels of SBP postoperatively.

Objective: To explore the mediation mechanism of coronary artery lesion among both male and female Kawasaki disease (KD) children. Methods: Children with KD that hospitalized in the Wenzhou Medical University affiliated Yuying Children’s Hospital from January 2009 to December 2014, were included in this study. Differences on demographical characteristics, clinical manifestations, laboratory indicators, regimen and time of treatment, results from pre/post echocardiography and treatment between male and female patients, were compared. The independent effect of gender on the risk of coronary artery lesions (CAL) was evaluated, and the mediating effect of BMI, visiting time and KD type on the association between gender and CAL were also studied. Results: The average BMI level of male patients was higher than that of female patients. The difference was statistically significant (P<0.001). The prevalence of overweight among male patients (20.9%) was higher than female (14.1%). The difference was statistically significant (P=0.011). Data from the multivariate logistic regression analysis confirmed that the incidence of CAL in male patients was higher than that in female patients (aOR=1.50, 95%CI: 1.06-2.12) but the CAL was mainly different before on the immunoglobulin therapy. Results from the mediation analysis showed that BMI was an important mediator in the association between gender and CAL, with the indirect effect as 1.05 (95%CI: 1.01- 1.10) and the proportion mediated as 13.0%. Conclusions Male patients presented higher incidence of CAL but was mainly reflected in the difference of CAL before the treatment. BMI was probably an important mediator related to the association between gender and CAL.

Objective? To understand the attitude toward hospice care and its infLuencing factors among undergraduate nursing students majoring in TraditionaL Chinese Medicine (TCM), and to provide basis for nursing educators to formuLate hospice care training strategies. Methods? Using convenient sampLing method, a totaL of 827 undergraduate nursing students from 3 TCM universities in Shandong, Shanxi and He'nan provinces were seLected as subjects from September to October 2018. The generaL information questionnaire and the Chinese version of FrommeLt Attitude Toward Care of the Dying (FATCOD) were used. MuLtipLe Linear regression was used to anaLyze infLuencing factors. ResuLts? The totaL score of FATCOD among the 827 undergraduate TCM nursing students was (101.32±9.15). Univariate Linear regression resuLts showed that gender, singLe-chiLd status, wiLLingness to choose nursing major, attitudes toward nursing, the situation where students discussed death with famiLy, experience with funeraLs, experience with terminaL reLatives, wiLLingness to take care terminaL patients were aLL factors that couLd affect the attitudes toward hospice care among nursing students (t/F=-3.066,-2.783, 3.289, 12.577, 10.638, 2.680, -2.251, 8.697;P＜0.05). MuLtipLe Linear regression anaLysis resuLts showed that gender, singLe-chiLd status, attitudes toward nursing, wiLLingness to take care terminaL patients, experience with funeraLs, the situation where students discussed death with famiLy, experience with terminaL reLatives have an impact on the attitude toward hospice care (P＜ 0.05). ConcLusions? The attitude toward hospice care among undergraduate TCM nursing students needs to be further improved. Educators shouLd adopt various methods of teaching to carry out death education according to the infLuencing factors, and to cuLtivate proper perception of death and improve the enthusiasm for hospice care.
