ObjectiveTo investigate the clinical efficacy and potential mechanism of Shengmai Jiuxin decoction in the treatment of acute decompensated heart failure （ADHF） with the traditional Chinese medicine （TCM） pattern of Qi and Yin deficiency， Yang deficiency， and blood stasis. MethodsA total of 68 patients diagnosed with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type were randomly assigned to an observation group （34 cases） and a control group （34 cases）. Both groups received conventional Western medical treatment， while the observation group was additionally administered Shengmai Jiuxin decoction. Parameters compared before and after treatment included： TCM syndrome score， TCM syndrome efficacy， New York Heart Association （NYHA） functional classification， left ventricular ejection fraction （LVEF）， N-terminal pro-B-type natriuretic peptide （NT-proBNP）， six-minute walk distance （6MWD）， hypoxia-inducible factor-1 alpha （HIF-1α）， vascular endothelial growth factor A （VEGF-A）， Caspase-3， and the number of rehospitalizations for heart failure within one month after discharge. ResultsThere were no significant differences in sex， age， vital signs， or underlying diseases between the two groups. Compared with baseline， both groups exhibited significant reductions in TCM syndrome scores， NT-proBNP， and HIF-1α levels （P<0.01）， as well as significant increases in 6MWD， LVEF， VEGF-A， and Caspase-3 levels （P<0.05， P<0.01）. After treatment， the observation group showed significantly greater reductions in TCM syndrome score， NT-proBNP， HIF-1α， and Caspase-3 levels compared with the control group （P<0.05） and significantly greater increases in 6MWD， TCM syndrome efficacy， and VEGF-A levels （P<0.05）. No significant differences were observed between the groups in NYHA functional classification， LVEF， or the number of rehospitalizations for heart failure within one month after discharge. No drug-related adverse events were reported in either group during the treatment period. ConclusionShengmai Jiuxin decoction can improve cardiac function and clinical symptoms in patients with ADHF of Qi and Yin deficiency， Yang deficiency， and blood stasis type. Its mechanisms may be related to the regulation of the HIF-1 signaling pathway by modulating targets such as HIF-1α， VEGF-A， and Caspase-3.

[Objective]To explore the micro-ecological mechanism of soil amendment combined with Trichoderma solution in resolving the replant obstacles of Atractylodes macrocephala through studying their effects on the microbial community structure in the rhizosphere soil.[Methods]In pot experiment and field experiment,different soil amendments and Trichoderma inoculants were applied to Atractylodes macrocephala,the survival rate,physiochemical properties of soil and microbial community were detected,as well as analysis of the microenvironmental changes in the rhizosphere.[Results]The number of leaves and survival rate were significantly increased after the application of lime(mainly composed of calcium oxide)and mixed bacterial solution;the activity of soil-urease(S-UE),soil-phosphatase(S-NP),solid-β-glucosidase(S-β-GC),soil-catalase(S-CAT)in the rhizosphere were also increased,indicating that the replant obstacle was alleviated.Meanwhile,the rhizosphere bacteria and fungi were the highest.The sequencing results showed that the bacteria in the rhizosphere soil after the application of lime and mixed bacterial solution were mainly composed of Gemmatimonadetes,Verrucomicrobia,Firmicutes,Actinobacteria,while the fungi were mainly composed of Ascomycetes,Mortierella,Basidiomycetes and Chytridiomycota,after the application of lime and mixed bacterial solution,the proportion of Fusarium decreased,and the proportion of Penicillium increased.[Conclusion]The combination of lime as a soil amendment and Trichoderma can effectively improve the replant disorder of Atractylodes macrocephala and promote the growth of Atractylodes macrocephala,which may be by improving the structure of the microbial communities in the rhizosphere,increasing the abundance of biocontrol bacteria and reducing the abundance of pathogenic bacteria.

Objective:To analyze the fail mode of neoadjuvant therapy combined with surgery for locally advanced esophageal squamous cell carcinoma (ESCC) after long-term follow-up.Methods:Clinical data of consecutive 238 patients with locally advanced resectable ESCC who underwent neoadjuvant therapy combined with surgery in Zhejiang Cancer Hospital from September 2012 to October 2019 were retrospectively analyzed. The failure mode in the whole cohort was analyzed after long-term follow-up. The overall survival (OS) and disease free survival (DFS) rates were analyzed by Kaplan-Meier method. Survival differences were determined by log-rank test.Results:The pathological complete response (pCR) rate was 42.0% in 238 patients. After a median follow-up of 46.1 months, tumor progression occurred in 96 patients (40.3%), including 25 patients (10.5%) with local recurrence, 61 patients (25.6%) with distant metastases, and 10 patients (4.2%) with simultaneous local recurrence and distant metastases. The median OS and DFS were 64.7 months and 49.9 months. And the 3-, 5-, and 7-year OS and DFS rates were 70.0%, 52.8%, 36.4% and 63.5%, 42.5%, and 30.0%, respectively. The 3-, 5-, and 7-year locoregional recurrence-free survival rates and distant metastasis-free survival rates were 86.0%, 71.4%, 61.2% and 70.6%, 55.9%, 43.0%. Compared with non-pCR patients, the overall progression rate and distant metastasis rate of pCR patients were lower (26.0% vs. 50.7%, 16.0% vs. 32.6%, both P<0.05). And the 3-, 5-, and 7-year OS (83.0% vs. 60.2%, 69.7% vs. 41.7%, 50.4% vs. 27.7%, all P<0.001) and DFS rates (80.4% vs. 51.4%, 63.9% vs. 31.2%, 45.9% vs. 20.3%, all P<0.001) were significantly better in pCR patients. Conclusions:Distant metastasis is the main failure mode of patients with locally advanced ESCC after neoadjuvant therapy. Patients with postoperative pCR can achieve better long-term survival.

Objective:To analyze the failure patterns and survival after stereotactic body radiotherapy (SBRT) in patients with T 1-2N 0M 0 non-small cell lung carcinoma (NSCLC). Methods:Clinical data of early-stage NSCLC patients who received SBRT at Zhejiang Cancer Hospital from January 2012 to September 2018 were retrospectively analyzed. The primary observed endpoint was the pattern of disease progression, which was divided into intra-field recurrence, regional lymph node recurrence and distant metastasis. Overall survival (OS) and progression-free survival (PFS) were calculated by Kaplan-Meier method. Univariate analysis was conducted by log-rank test, and multivariate analysis was performed by Cox's model.Results:A total of 147 patients with 156 lesions were included. The median follow-up time was 44.0 months (16.5-95.5 months). A total of 57 patients (38.8%) progressed: 14 patients (24.5%) had recurrence with the 1-, 3-, and 5-year local recurrence rates of 2.0%, 10.9%, and 14.3%, respectively; 36 patients (63.2%) had Distant metastasis with the 1-, 3- and 5-year distant metastasis rates of 12.2%, 22.4% and 28.6%, respectively; and 7 patients (12.3%) had recurrence complicated with distant metastasis. The 3-, 5- and 7-year OS rates were 80.5%, 64.2% and 49.9% for all patients, respectively. The median OS was 78.4 months. The 3-, 5- and 7-year PFS rates were 64.8%,49.5% and 41.5%, with a median PFS of 57.9 months (95% CI: 42.3-73.5 months). Univariate and multivariate analyses showed that biologically equivalent dose and age were the factors affecting the efficacy of SBRT (both P<0.05). Conclusion:Distant metastasis is the main failure pattern in patients with T 1-2N 0M 0 NSCLC after SBRT. High-risk population should be selected for further systematic treatment to improve the efficacy.

Objective: To explore the activity of auranofin against ovarian cancer cells and its possible molecular mechanism． Methods : The dose-response survival curve and IC50 of auranofin on ovarian cancer cell lines ，SKOV3，Caov3 and SW626 cells and immortalized normal human embryonic kidney HEK-293T cells were determined by CCK-8 method．Cell cycle was determined by flow cytometry．The levels of total glutathione ( GSH) ，reduced GSH and glutathione disulfide ( GSSG) ，thioredoxin reductase (TrxR) and reactive oxygen species (ROS) in cells were determined by microplate reader，and the reduced GSH / GSSG ratio was calculated．Western blot was used to determine the expression of cyclin dependent kinases( CDK) 4，CDK6，Cyclin D1，P53，p-P53 and MDM2 in SKOV3 and Caov3 ovarian cancer cells. Results : Compared with HEK-293T cells，the dose-response survival curves and IC50 values of SKOV3，Caov3 and SW626 cells showed that ovarian cancer cells were more sensitive to auranofin (P＜0. 05) ．After SKOV3 and Caov3 cells were treated with the dose of respective IC50 concentrations of auranofin，compared with the untreated cells group，the Auranofin IC50 group cells' intracellular levels of GSH，the ratio of reduced GSH / GSSG and the activity of TrxR decreased (t = 25. 11 /31. 18，14. 72 /19. 92，43. 30 /10. 74， all P＜0. 05) ，and the levels of ROS increased (t = 23. 82 /27. 71，P＜0. 05) ; cells number at G0 / G1 phases increased，with cells number at S and G2 phases decreased (P＜0. 05) ; and the expression levels of cell cycle-related proteins CDK4，CDK6，Cyclin D1 and the P53-specific E3 ubiquitin ligase MDM2 were down-regulated (t = 7. 51 /15. 59，17. 32 /11. 26，20. 78 /20. 78，24. 25 /17. 32，all P＜0. 05) ，while the expression levels of P53 and p-P53 were up-regulated (t = 17. 32 /24. 25，12. 12 /10. 39，all P ＜0. 05) ． Conclusion Auranofin causes oxidative stress in ovarian cancer cells by inhibiting TrxR activity，and by partially degrading MDM2 to stabilize and acti- vate P53，so as to block the cancer cells in G0 / G1 phase，and exert anti-ovarian cancer activities.

Background Because of high working intensity, high responsibility, and unexpected situations, health care workers may suffer great work pressure, which may lead to health damage. Objective To explore the self-rated health status and its influencing factors such as demographic and occupational-related factors of medical staff in Lanzhou. Methods In-service medical staff were selected by using cluster random sampling method from 18 public hospitals in Lanzhou City and were investigated with a self-made questionnaire and the Self-rated Health Measurement Scale (SRHMS). SRHMS includes 48 items in 10 dimensions, which are divided into three sub-scales of physical health, mental health, and social health, and another independent dimension is overall health. The scores were converted into a percentage scale and expressed as the percentage of measured score to full score; a higher score indicated better health, and >70% was considered good health status. t test, Kruskal-Wallis H test, and Spearman correlation were used to analyze the scores of SRHMS and the demographic and occupational-related factors affecting the scores of physical, mental, and social health sub-scales. Results A total of 2989 valid questionnaires were recovered. There were statistically significant differences in total score and the scores of physical, mental, and social health among medical staff of different age, educational background, length of service, and weekly working hours groups (P < 0.05). The percentage of total score to full score in the medical staff was 71.41%, but the scores of physical, mental, and social health sub-scales and total scale of selected participants were all lower than the corresponding domestic norms (t=−3.323, −12.283, −7.157, −9.659, P < 0.05); the percentage of psychological symptoms and negative emotions in mental health scale to full score was the lowest, only 58.39%. Educational background, length of service, and weekly working hours were negatively correlated with physical health score (r=−0.061, −0.060, −0.165, P < 0.05); professional title was positively correlated with mental health score (r=0.045, P < 0.05), while educational background and weekly working hours were negatively correlated with it (r=−0.051, −0.172, P < 0.05). Monthly income, professional title, and length of service were positively correlated with social health score (r=0.040, 0.049, 0.071, P < 0.05), while educational background and weekly working hours were negatively correlated with it (r=−0.038, −0.110, P < 0.05). Conclusion The self-rated health status of selected medical staff in Lanzhou is generally good, but lower than that of the norm, especially the mental health score is the lowest. The self-rated health score of total scale is correlated with education, length of service, professional title, and working time per week.

Canine cognitive dysfunction syndrome (CDS) is a neurodegenerative disease that causes cognitive and behavioral disorders and reduces the quality of life in dogs and their guardians. This study reviewed the complementary and alternative medicine (CAM) for CDS and compared the diagnosis and therapy of CAM between CDS in canines and dementia in humans. The evaluation tools for the diagnosis of CDS and dementia were similar in the neurological and neuropsychiatric examinations, daily life activity, cognitive tests, and neuroimaging, but the evaluation for dementia was further subdivided. In CAM, pattern identification is a diagnostic method for accurate, personalized treatment, such as herbal medicine. For herbal medicine treatment of cognitive impairment in canines and humans, a similar pattern identification classified as deficiency (Qi, blood, and Yin) and Excess (phlegm, Qi stagnation, and blood stasis) is being used. However, the veterinary clinical basis for verifying the efficacy and safety of CAM therapies for CDS is limited. Therefore, based on CAM evidence in dementia, it is necessary to establish CDS-targeted CAM diagnostic methods and therapeutic techniques considering the anatomical, physiological, and pathological characteristics of dogs.

Objective:To evaluate the 5-year survival outcome of patients with unresectable locally advanced non-small cell lung cancer (NSCLC) treated with Endostar in combination with platinum-based concurrent chemoradiotherapy.Methods:From March 2009 to June 2015, 115 patients with the unresectable locally advanced NSCLC from two prospective studies[Clinical trials 2009-2012(ClinicalTrials.gov NCT01894) and 2012-2015(ClinicalTrials.gov, NCT01733589)] were treated with Endostar in combination with platinum-based concurrent chemoradiotherapy. A total dose of 60-66 Gy was delivered in 30-33 fractions. Endostar was given 1 week prior to the beginning of radiotherapy, and repeated fortnightly during the concurrent chemoradiotherapy. After long-term follow up, survival outcome was evaluated in 104 patients treated with radiation dose of ≥60 Gy. Kaplan-Meier method was used for survival analysis. Univariate survival analysis was performed using the log-rank test.Results:Of 104 eligible patients, 60.6% of them had squamous carcinoma and 65.4% were classified in stage Ⅲ B. All the patients received ≥2 cycles of Endostar and 93.3% of them received 4 cycles of Endostar. The median follow-up time was 68.3 months. The median overall survival (OS) and median progression-free survival (PFS) were 31.3 and 13.9 months, respectively. The 3-year and 5-year OS were 45.6% and 35.7%, respectively. The 3-year and 5-year PFS were 27.1% and 24.9%, respectively. Univariate analysis indicated that sex, ECOG, pathological type, clinical stage, radiotherapy technique, chemotherapy regimen, chemotherapy cycle and cycle of Endostar use were not associated with OS. Late radiation injury occurred in 14.4% of patients, and no grade 4-5 late injury was observed. Conclusion:Patients with unresectable locally advanced NSCLC treated with Endostar fortnightly in combination with platinum-based concurrent chemoradiotherapy achieve better OS than historical data with tolerable toxicities.

【Objective】 To investigate the effects of RASSF6 gene on gastric cancer cells’ proliferation， autophagy， apoptosis， and sensitivity to oxaliplatin chemotherapy. 【Methods】 Gastric cancer BGC823 cells were cultured in vitro and divided into experimental control group （control group）， RASSF6 overexpression group （Oe group）， RASSF6 interference group， and lentivirus control group according to the expression effect of lentivirus gene. The changes in cell proliferation， cell cycle distribution， cell migration， autophagy， apoptosis and sensitivity to oxaliplatin in each group were detected， and the number of autophagy bodies in each group was detected by electron microscopy. Real-time PCR （qRT-PCR） and Western blotting were used to detect the expression levels of apoptosis- and autophagy-related genes in each group. 【Results】 Studies on the biological behavior of gastric cancer BGC823 cells induced by RASSF6 gene expression showed that compared with the control group， the percentage of G0/G1 phase cells in the Oe group increased， while the percentage of G2 and S phase cells decreased， with statistical significance （P<0.05）. The apoptosis rate was significantly increased （P<0.05）. The cell scratch assay showed that the scratch healing rate was significantly decreased （P<0.05）. Studies on the sensitivity of RASSF6 gene expression to oxaliplatin showed that compared with the drug group （L-OHP group）， the apoptosis rate of Oe+L-OHP group was increased significantly （P<0.05）. In the Oe+L-OHP group， the expression of anti-apoptotic protein Bcl-2 decreased， the expressions of Bax and Caspase-3 were increased； the expression of autophagosomes was increased； the expressions of Beclin-1 and P62 and the ratio of LC3-Ⅱ/LC3 were all increased （P<0.05）. 【Conclusion】 The RASSF6 gene plays a role in suppressing gastric cancer cell BGC823， which can increase the sensitivity to oxaliplatin chemotherapy by promoting apoptosis and autophagy.
