Abstract
Objective: To investigate the expressions of migration and invasion inhibitory protein (MIIP) and p21-activated kinase 1 (PAK1) in endometrial carcinoma (EC) and their correlation with clinicopathological features. Methods: The protein levels of MIIP and PAK1 in 135 paraffin-embedded EC tissues, 55 atypical hyperplasia of endometrium (AHE) and 88 normal endometrium (NE) tissues were quantified by immunohistochemistry, the clincial significance and the relationship of these two proteins were also analyzed. Results: The positive rates of MIIP expression in NE, AHE and EC tissues were 52.3%(46/88), 41.8% (23/55) and 34.8% (47/135), respectively. The expression of MIIP in EC was significantly lower than that of MIIP in NE (P<0.05). The positive rates of PAK1 expression in NE, AHE and EC tissues were 45.5% (40/88), 50.9% (28/55) and 62.2% (84/135), respectively. The expression of PAK1 in EC tissues was significantly higher than that of PAK1 in NE tissues (P<0.05). The expression of MIIP in EC tissues was significantly associated with myometrial invasion, International Federation of Gynaecology and Obstetrics (FIGO) stage and lymph node metastasis (P<0.05). The expression of PAK1 in EC tissues was significantly related with differentiation, myometrial invasion, FIGO stage and lymph node metastasis (P<0.05). The expressions of MIIP and PAK1 in EC tissues were marginally related with the overall survival of patients (P=0.092, P=0.052). The expression of MIIP in EC was negatively correlated with PAK1 (r=-0.329, P<0.001). Conclusions: The down-regulation of MIIP and up-regualtion of PAK1 paticipate in the initiation and development of EC, which are correlated with the poor prognosis of EC. The protein expression of MIIP is inversely related with PAK1 in EC.

Abstract
Microcin J25 (MccJ25) is an antimicrobial peptide produced by a fecal strain of Escherichia coli containing 21 AA. This study was performed primarily to evaluate the effects of MccJ25 as a potential substitute for antibiotics (AB) on growth performance, nutrient digestibility, fecal microbiota, and intestinal barrier function in weaned pigs. In the present study, 180 weaned pigs (7.98 ± 0.29 kg initial BW) were randomly assigned to 1 of 5 treatments, including a basal diet (CON) and CON supplemented with AB (20 mg/kg colistin sulfate; ABD) or 0.5, 1.0, and 2.0 mg/kg MccJ25. On d 0 to 14, dietary supplementation with MccJ25 and ABD had positive effects on ADG, ADFI, diarrhea incidence, and G:F ( < 0.05). Pigs fed the 2.0 mg/kg MccJ25 diet had greater ADG ( < 0.05) and marginally greater G:F ( < 0.10) compared with pigs fed the ABD diet. Compared with the CON diet, the 2.0 mg/kg MccJ25 diet sharply improved ( < 0.05) ADG and G:F and decreased ( < 0.05) diarrhea incidence (d 15 to 28 and d 0 to 28). Apparent digestibility of nutrients in pigs fed 1.0 and 2.0 mg/kg MccJ25 was improved ( < 0.05) compared with that of pigs fed CON and ABD. The serum cytokines IL-6 and IL-1β and tumor necrosis factor-α levels in pigs fed MccJ25 were greater than in pigs fed CON ( < 0.05). Additionally, the IL-10 concentration in pigs fed MccJ25 was sharply increased ( < 0.05) compared with that of pigs fed CON. Pigs fed 1.0 and 2.0 mg/kg MccJ25 diets had remarkably decreased lactate, diamine oxidase, and endotoxin concentrations and fecal numbers ( < 0.05) and improved fecal and numbers ( < 0.05). Compared with the ABD diet, the diet containing 2.0 mg/kg MccJ25 did not increase lactate, diamine oxidase, and endotoxin (d 14) concentrations ( < 0.05) or decrease the and (d 28) numbers ( < 0.05). The diets containing 1.0 and 2.0 mg/kg MccJ25 and ABD (d 28) improved lactate concentration and short-chain fatty acid concentrations, including acetate, propionate, and butyrate, in feces ( < 0.05). Moreover, the pigs fed 2.0 mg/kg MccJ25 had greater lactate, butyrate (d 14), and propionate concentrations than the pigs fed the ABD diet ( < 0.05). In conclusion, dietary supplemented MccJ25 effectively improved performance, attenuated diarrhea and systematic inflammation, enhanced intestinal barrier function, and improved fecal microbiota composition of weaned pigs. Therefore, MccJ25 could be a potential effective alternative to AB for weaned pigs.

Abstract
Objective: To compare the bioequiavailability of paclitaxel for injection (albumin bound) (PAB) and reference listed drug abraxane in the patients with metastatic breast cancer, and to investigate the safety and efficacy in the extension treatments of PAB. Methods: This study was random, two cycles, self-crossover control study in the bioequiavailability stage. PAB was the investigational drug T and Abraxane was the reference drug R. Patients were randomly assigned to two cycles therapy of either R→T or T→R(260 mg/m(2)/21d). Non-PD patients entered in the extension treatments of the investigational drug PAB(260 mg/m(2)/21d) until the disease progression or the intolerance toxicity. Results: From Mar 1, 2016 to May 24, 2016, we enrolled 40 patients. The blood concentration-time curve and the parameters of pharmacokinetics indicated the two drugs were the bioequivalent drug products in the initial two cycles crossover-therapy.The incidence of adverse drug reactions were 89.7% vs 97.4% in investigational drug vs reference drug and grade 3/4 toxicities were 20.5% vs 21.1%(P=1.000). Patients received a median of 7 treatment cycles(range 1-23) and a median of 260mg/m(2) actual drug dose (range 220-260 mg/m(2)). Seven patients (17.5%) had dose reductions because of toxicities (260 mg/m(2) reduce to 220 mg/m(2)). Twenty-two patients (55%) discontinued treatment prematurely because of toxicity.Overall response rates (ORR) were 40% (95% CI, 24.8%-55.2%). For patients who received PAB as first-line vs non-first-line therapy, the ORR were 43.8% vs 25%. For patients who taxane-naïve vs taxane-pretreated, the ORR were 45.5% vs 37.9%. Median PFS was 49 weeks(95% CI, 30weeks-NA). Conclusion: The paclitaxel for injection (albumin bound) (PAB) and reference listed drug abraxane are the bioequivalent drug products.The toxicity and efficacy of the PAB are similar with abraxane.The more therapy chances for Chinese patients will come by the research and development of domestic drugs.

Abstract
Fires resulting from titanium combustion are complex and violent processes which can instantly burn a titanium alloy once ignited. The occurrence of titanium combustion is a disaster for aircraft. Accurate measurement of the ignition temperature of titanium alloys is of significance in preventing such fires and in investigating combustion-resistance properties. In this study, monochromatic temperature and emissivity measurement methods based on reflectivity detection were used to determine the ignition temperature of a titanium alloy. Experiments were carried out using a titanium burning apparatus. The temperatures of titanium in the oxidation stage before ignition and in the combustion stage during the ignition process were measured using wavelengths of 1050 nm and 940 nm, respectively. Experimental results showed that the ignition temperature of the titanium alloy could be measured by reflectivity detection and that measurement precision during thermal oxidation (500-900 °C) was ±1 °C. The temperature of the ignition process ranged between 1653 and 1857 °C, and the ignition temperature was around 1680 °C.

Abstract
To determine if plasma exchange combined with plasma perfusion is a reliable and effective temporary liver support treatment for patients on the waiting list for OLT, we tested this method in 5 patients with end-stage and 3 patients with middle-stage severe hepatitis. Four patients were successfully controlled until a donor liver was available 4 to 13 days later. In contrast, the remaining 4 patients were not adequately controlled by this treatment and experienced aggravated disease progression, dying 3 to 8 days after treatment while still awaiting OLT. Of those 4 patients who received OLT, 2 patients died from multi-organ failure caused by hepatic failure, while the other 2 survived. These findings show that plasma exchange combined with plasma perfusion provides temporary support for some patients on the waiting list for OLT. The ability of patients to successfully bridge to OLT is closely associated with the degree of liver failure, complications, multi-organ failure, and the length of the waiting period for a donor liver.

Abstract
In the field of emotion research, the influence of emotion regulation strategies on memory with emotional materials has been widely discussed in recent years. However, existing studies have focused exclusively on regulating negative emotion but not positive emotion. Therefore, in the present study, we investigated the influence of emotion regulation strategies for positive emotion on memory. One hundred and twenty college students were selected as participants. Emotional pictures (positive, negative and neutral) were selected from Chinese Affective Picture System (CAPS) as experimental materials. We employed a mixed, 4 (emotion regulation strategies: cognitive up-regulation, cognitive down-regulation, expressive suppression, passive viewing) × 3 (emotional pictures: positive, neutral, negative) experimental design. We investigated the influences of different emotion regulation strategies on memory performance, using free recall and recognition tasks with pictures varying in emotional content. The results showed that recognition and free recall memory performance of the cognitive reappraisal groups (up-regulation and down-regulation) were both better than that of the passive viewing group for all emotional pictures. No significant differences were reported in the two kinds of memory scores between the expressive suppression and passive viewing groups. The results also showed that the memory performance with the emotional pictures differed according to the form of memory test. For the recognition test, participants performed better with positive images than with neutral images. Free recall scores with negative images were higher than those with neutral images. These results suggest that both cognitive reappraisal regulation strategies (up-regulation and down-regulation) promoted explicit memories of the emotional content of stimuli, and the form of memory test influenced performance with emotional pictures.

Abstract
Mutations in the mitochondrial (mt) genome that result in mt dysfunction, have long been proposed to play important roles in the pathogenesis of hepatocellular carcinoma (HCC). Among these, the common mtDNA 4977 bp deletion is one of the most frequent mutations observed in various cancers. To understand the relationship between the mtDNA 4977 bp deletion and HCC, we performed mutational screening for the presence of this deletion in 105 HCC patients and 69 unrelated healthy subjects. After nested-polymerase chain reaction (nested-PCR) amplification, we found that there were 10 patients carrying the mtDNA 4977 bp deletion, and this deletion was absent in control subjects. Moreover, HCC patients carrying this deletion showed a marked increase in reactive oxygen species (ROS) level and mtDNA copy number when compared with the healthy controls. Taken together, our data indicated that the mtDNA 4977 bp deletion may play important role in the carcinogenesis of HCC, possibly via the alternation of mtDNA copy number and oxidative stress.

Abstract
Objcetive: To investigate the incidence and risk factors of Lymphocele infection and the optimal timing for drainage after pelvic lymphadenectomy. Methods: This retrospective study was carried out on 397 patients who received a pelvic lymphadenectomy with or without a para-aortic lymphadenectomy between January 2009 and April 2016, due to endometrial cancer in General hospital of Tianjin medical university.A total of 76 patients developed lymphocele and 20 patients developed lymphocele infection. Results: (1)The incidence of lymphocele infection was 5.04% (20/397). Single factor analysis indicated diameter of lymphocele ≥5 cm and postoperative anemia were associated with lymphocele formation (P<0.001, P=0.023). Multiple factors Logistic analysis through the adjustment of the factors showed diameter of lymphocele ≥5 cm was the independent risk factors for lymphocyst infection (P<0.001). (2)The total treatment period of cases treated only with antibiotics tended to be shorter than that of cases treated with combined antibiotics and drainage (P=0.008). However, for severe cases which needed drainage, initiating the drainage by day 3 significantly shortened the total treatment period compared with cases started on or after day 4 (P=0.048). Conclusion: To identify the risk factors of the lymphocele infection is useful to help reduce the incidence of them with effective measurement.When drainage is required in addition to antibiotics, the earlier the drainage is performed, the shorter the treatment period is.

Abstract
Visfatin is a cytokine secreted by visceral adipose tissue, which plays an important role in obesity, diabetes, insulin resistance, atherosclerosis and polycystic ovarian syndrome. Additionally, visfatin is also involved in the metabolic syndrome-associated malignancies such as breast, colon, gastric and endometrial cancers. Visfatin inhibitor might be a potential antitumor therapeutic strategy for inhibiting the growth of many cancers.

Abstract
The relaxation of amorphous materials, i.e., aging, would largely endanger their performances in service. Here we report a mechanical relaxation-to-rejuvenation transition of a Zr35Ti30Be27.5Cu7.5 bulk metallic glass (BMG) in elastostatic compression at ambient temperature, thus provide an accessible way to tailor the mechanical properties of amorphous materials. To unravel the structural evolution underlying the observed transition, atomistic simulations parallel with the experimental tests on a typical model glass system Zr60Cu40 were performed, which successfully reproduced and thus upheld the experimentally observed mechanical relaxation-to-rejuvenation transition. The variations of coordination number and atomic volume during the transition are evaluated to indicate a de-mixing tendency of the constituent atoms in the rejuvenation stage. This de-mixing tendency largely explains the difference between mechanical rejuvenation and thermal rejuvenation and reveals a competitive relationship between activation enthalpy and activation entropy in the stress-driven temperature-assisted atomic dynamics of BMG, such as diffusion and plastic deformation etc.

Abstract
Objective: To investigate the morphologic, immunohistochemical, genetic, clinical features and prognosis of Ewing-like BCOR-CCNB3 gene fusion undifferentiated sarcoma (BCOR-CCNB3 fusion sarcoma). Method: Seventeen Ewing-like sarcoma cases were screened for CCNB3 expression and BCOR-CCNB3 fusion transcripts by immunohistochemistry and RT-PCR among 260 cases of Ewing-like sarcomas collected during Jan, 2006 to Dec, 2015. Three cases of BCOR-CCNB3 fusion sarcoma were found among 17 atypical Ewing sarcomas, and follow-up were conducted. Results: The harboring of BCOR-CCNB3 fusion transcript was confirmed by RT-PCR and directly sequencing results. The three patients aged between 8 and 11 years old. Two of them were male and the other one was female. One patient achieved a complete response after chemotherapy, the other two died without chemotherapy after surgical excision in 12 months. Tumor cells in all 3 cases showed diffuse nuclear CCNB3, TLE1 and cyclin D1 positivity, while CCNB3 (0/12), TLE1 (1/12) and cyclin D1 (4/12) positivity was infrequent in the 12 cases of classical Ewing's sarcoma. The oval or plump spindle tumor cells with fine chromatin arranged in solid pattern, the nucleoli was inconspicuous. The delicate capillary networks were obvious in the tumor. Conclusion: With a detailed description of the histological spectrum, immunohistochemical features and clinical characteristic of BCOR-CCNB3 sarcoma, justify distinction from Ewing sarcoma could be possible.

Abstract
Objective: To investigate the clinicopathologic features and grading of adenoid cystic carcinoma (ACC) of the breast. Methods: Sixteen cases of ACC of the breast were analyzed and graded according to the previous report. Immunohistochemical (IHC) staining was used to detect the immunophenotype, Ki-67 proliferative index and expression of EZH2, and the association with tumor grade and outcome was analyzed. Results: Of the 16 cases, 11 were grade Ⅰ, with the epithelial and myoepithelial cells being arranged into tubular and cribriform structure with no solid component; three were grade Ⅱ, which were composed of mixed tubular, cribriform and solid component (<30%); and two were grade Ⅲ, which showed mainly solid component (>90%) and the tumor cells showed basaloid features with scanty cytoplasm and hyperchromatic nuclei, and mitotic count was>5/10 HPF. Immunophenotypically, the epithelial cells expressed CK7, CK8/18 and CD117; the myoepithelial cells expressed p63 and CK5/6; while the basaloid cells were positive for CK5/6 and CD117.Tubular and cibriform ACC showed low Ki-67 and EZH2 expression, while the two cases of solid variant with basaloid features showed high level of Ki-67 and EZH2 expression. Follow-up data were available in 13 cases with a median follow-up period of 42 months. Lung metastasis occurred after 12 months in one grade Ⅱ case and the patient died of disease after 34 months. Vertebral metastasis occurred after 12 months in one grade Ⅲ case and axillary lymph node metastasis occurred in another grade Ⅲ case. All other patients were free of disease at the end of the follow-up periods. Conclusions: ACC shows morphologic spectrum varying from low to high grade, the latter can may give rise to local and distant metastasis. ACC should not be regarded simply as low malignant potential, and should be graded for optimal treatment.

Abstract
Objective: To investigate the significant role of the clinical application of adult comorbidity evaluation-27 (ACE-27) in endometrial cancer (EC). Methods: A total of 847 EC patients were included during Jan. 1985 to Dec. 2015 from Tianjin Medical University General Hospital. The clinical data of the patients were collected and analyzed retrospectively. All of the patients were received operation with no chemotherapy and radiotherapy before operation. The average age was 57.6 years old (range from 25 to 85 years old). The average follow-up period was 59.0 months (range from 2 to 312 months). The comorbidity of the patients was evaluated by ACE-27. EC patients survival was analyzed by Kaplan-Meier survival curve. The relationship between the prognosis of EC and ACE-27, age, body mass index (BMI) , pathological characteristic were showed by Cox modeling. Results: (1) The patient number of score 0, 1, 2 and 3 of ACE-27 in EC patients were respectively 311 (36.7%), 263 (31.1%), 132 (15.6%) and 141 (16.6%) cases. (2) Kaplan-Meier survival curve analysis showed that overall survival time of EC patients was gradually decreased as increased score of ACE-27 (χ2=19.003, P=0.000) . In the patients of BMI<25 kg/m2 and BMI 25-<30 kg/m2, International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ, endometrial adenocarcinoma type and the overall survival time of those EC patients were gradually decreased as increased score of ACE-27 (P<0.05) . However, there was no statistically significant difference in overall survival time for patients with BMI ≥30 kg/m2, FIGO stage with Ⅱ-Ⅳand non-endometrial adenocarcinoma type (P>0.05). Per unvariate logistic modeling showed that the risk of death in score 3 of ACE-27 was increased compared with score 0 of ACE-27 (OR=2.53, P=0.000) . The overall survival time in EC patients with aged 50-59, 60-69 and ≥70 years old, BMI 25-<30 kg/m2 and ≥ 30 kg/m2, G3, FIGO stage Ⅱ-Ⅳ and non-endometrial adenocarcinoma type were significantly decreased compared with those aged <50 years old, BMI < 25 kg/m2, G1, FIGO stage Ⅰ and endometrial adenocarcinoma type (all P<0.05) . Further we found that postoperative chemotherapy or radiotherapy rate were decreased for EC patients with FIGO staging Ⅲ or Ⅳ as the increase of ACE-27 score, but there was no statistically significant difference (P>0.05). (3) Per multivariate logistic modeling showed that the risks of death in score 3 of ACE-27 was increased compared with score 0 of ACE-27 among age-adjusted, BMI, histological grade, FIGO stage and pathologic type (OR=2.40, P=0.000) . Per multivariate logistic modeling showed that, the overall survival time in EC patients with aged 60-69 and ≥70 years old, BMI 25-<30 kg/m2 and ≥30 kg/m2, FIGO stage Ⅲ-Ⅳ and non- endometrial adenocarcinoma type remain significantly decreased compared with those aged <50 years old, BMI<25 kg/m2, FIGO stage Ⅰ and endometrial adenocarcinoma type (P<0.05) , but there was no statistically significant difference in histological grade (P>0.05). Conclusions: ACE-27 may become one of the factors of predictive therapy and the prognosis for EC patients. The detailed clinical data of comorbidity should be collected to evaluate prognosis and therapy plan.

Abstract
Chinese Fusion Engineering Test Reactor (CFETR) is a new superconducting tokamak device being designed in China, which aims at bridging the gap between ITER and DEMO, where DEMO is a tokamak demonstration fusion reactor. Two diagnostic cases, ITER-like case and towards DEMO case, have been considered for CFETR early and later operating phases, respectively. In this paper, some preliminary consideration of ITER-like case will be presented. Based on ITER diagnostic system, three versions of increased complexity and coverage of the ITER-like case diagnostic system have been developed with different goals and functions. Version A aims only machine protection and basic control. Both of version B and version C are mainly for machine protection, basic and advanced control, but version C has an increased level of redundancy necessary for improved measurements capability. The performance of these versions and needed R&D work are outlined.

Abstract
A new multi-channel poloidal correlation reflectometry is developed at Experimental Advanced Superconducting Tokamak. Eight dielectric resonator oscillators with frequencies of 12.5 GHz, 13.5 GHz, 14.5 GHz, 15 GHz, 15.5 GHz, 16 GHz, 17 GHz, and 18 GHz are used as sources. Signals from the sources are up-converted to V band using active quadruplers and then coupled together. The output waves are launched by one single antenna after passing through a 20 dB directional coupler which can provide the reference signal. Two poloidally separated antennae are installed to receive the reflected waves from plasma. The reference and reflected signals are down-converted by mixing with a quadrupled signal from a phase-locked source with a frequency of 14.2 GHz and the IF signals pass through the filter bank. The resulting signals from the mixers are detected by I/Q demodulators. The setup enables the measurement of density fluctuation at 8 (radial) × 2 (poloidal) spatial points. A coherent mode with an increasing velocity from 50 kHz to 100 kHz is observed by using the system. The mode is located in the steep gradient region of the pedestal.

Abstract
OBJECTIVE To study the oxidative damage of PM2.5 in human embryonic stem cells (EBf-H9 cells), and to provide a theoretical basis for revealing the adverse health effects of PM2.5 and the potential mechanisms, and also to provide a new alternative cell model for PM2.5 risk assessment. METHODS EBf-H9 cells were cultured with 0.00 (the constrast group) 3.91, 7.81, 15.63, 31.25, 62.50, 125.00 μg/cm(2) of PM2.5. CCK-8 kit was used to determine the survival rate of cells exposed to PM2.5 for 6 h. DCFH-DA probe was used to detect the total ROS content of cells exposed to PM2.5 for 1 h. The activities of total superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-Px), and the content of lipid peroxides such as malondialdehyde (MDA) in cells exposed to PM2.5 for 6 h were detected by using the commercial kits. ANOVA model analyzed the statistical significance from the different concentration group. RESULTS The cytotoxicity results showed that the cell survival rate was decreased gradually with the increase of the concentrations of PM2.5, and the half inhibitory concentration (IC50) was 83.01 μg/cm(2). When the exposure concentration was 3.91, 7.81, 15.63, 31.25, 62.5 μg/cm(2), after exposure of PM2.5 1 h, the ROS florescence was 27.12±0.21, 54.03±0.50, 60.93±0.08, 61.36±1.00, 68.21±0.93, 78.27±1.26 (compared to control group 27.12±0.21, all P level<0.01). After exposure of PM2.5 6 h, the activities of T-SOD was (9.78±0.28), (8.59±0.22), (8.90±0.33), (7.46±0.71), (4.21±0.17) U/mg protein (F=98.881, compared to control group (11.77±0.63) U/mg protein, all P level<0.01). The activities of GSH-Px was (181.59±3.65), (153.33±1.69), (168.74±2.22), (81.56±0.56), (48.62±2.13) U/mg protein (compared to control group (273.90±6.50) mU/mg protein, all P level<0.01). And the content of MDA was (0.38±0.03), (0.43±0.09), (0.47±0.09), (0.65±0.10), (0.70±0.12) nmol/mg protein (compared to control group (0.27±0.02) nmol/mg protein, all P level<0.05). CONCLUSION PM2.5 exposure can decrease EBf-H9 cells viability, and improve the levels of lipid peroxidation. It may be due to induce EBf-H9 cells to increase the production of ROS and to make the cells appear oxidative stress, which lead to oxidative damage to cells. The present study reveals the mode of action of PM2.5 in terms of oxidative damage to EBf-H9 cells. It is also indicated that the cells may be a new alternative cell model for PM2.5 risk assessment.

Abstract
OBJECTIVE To investigate the association between different long term systolic blood pressure variability (SBPV) and cognitive function in middle-aged and elderly people. METHODS A total of 101 510 employees from the Tangshan Kailuan Group participated in the 2006-2007 annual physical examination, 5 440 cases were selected by simple randomly sampling method. After excluding participants who did not underwent 2012-2013 examination and without complete blood pressure and mini-mental state examination (MMSE) score, 3 002 participants (1 627 males, (50.86±9.93) years old) with integrated data were included into the study. The long term SBPV was calculated by standard deviation(SD), maximum-minimum difference(MMD), average real variability (ARV) of mean systolic blood pressure measured in 2006-2007, 2008-2009, 2010-2011 and 2012-2013. Participants were grouped by the quartile of the different SBPV index. Multiple linear regressions analysis was used to analyze the correlation between the long term SBPV and cognitive function status. RESULTS (1) The score of MMSE was 28.03±2.65. (2) The observation population was divided into four groups according to quartiles of different SBPV, respectively. The MMSE scores of SD<5.53 mmHg (1 mmHg=0.133 kPa)group, SD 5.53-8.90 mmHg group, SD 8.91-12.79 mmHg group and SD>12.79 mmHg group were 28.21±2.18, 28.26±3.09, 28.10±2.40 and 27.56±2.79, respectively(P<0.05). The MMSE scores of MMD<12.00 mmHg group, MMD 12.00-20.00 mmHg group, MMD 20.01-30.00 mmHg group and MMD>30.00 mmHg were 28.27±2.17, 28.25±3.09, 27.99±2.42 and 27.49±2.81, respectively(P<0.05). The MMSE scores of ARV<6.67 mmHg group, ARV 6.67-10.22 mmHg group, ARV 10.23-15.56 mmHg group and ARV>15.56 mmHg group were 28.27±2.20、28.28±3.20、28.00±2.42、27.57±2.65, respectively(P<0.05). (3) Adjusted for age, gender, baseline systolic blood pressure, body weight index, total cholesterol, fasting blood glucose, triglyceride, C reactive protein, smoke, drink, physical activity , the step-wise regressions analysis showed that SD(B=-0.129, P<0.05), MMD(B=-0.131, P<0.05), ARV(B=-0.125, P<0.05) had significant negative linear relationship with the MMSE score in the objects not taking the anti-hypertension drugs, and SD(B=-0.329, P<0.05), MMD(B=-0.314, P<0.05), but not ARV(B=-0.233, P>0.05), had significant negative linear relationship with the MMSE score in the objects taking the anti-hypertension drugs. CONCLUSION The long term SBPV indexes (SD, MMD, ARV ) are negatively correlated with the MMSE score in middle-aged and elderly people not taking the anti-hypertension drugs, and SD, MMD are negatively correlated with the MMSE score in people taking the anti-hypertension drugs.

Abstract
Over-utilization of germplasms that are resistant to the soybean cyst nematode (SCN) in soybean breeding programs can lead to genetic vulnerability in resistant cultivars. Resistant wild soybean (Glycine soja) is considered an invaluable gene source for increasing the genetic diversity of SCN resistance. In this study, we genotyped 23 G. soja accessions that are resistant to SCN race 3 for polymorphisms in the resistance genes, rhg1, Rhg4, and SHMT, and investigated their genetic relationship with eight Glycine max resistant cultivars. We identified 89 single nucleotide polymorphisms (SNPs) and 11 DNA insertion-deletions (InDels), of which 70 SNPs and 8 InDels were found in rhg1, 9 SNPs were found in Rhg4, and 10 SNPs and 3 InDels were found in SHMT. Nucleotide diversity was π = 0.00238 and θ = 0.00235, and haplotype diversity was 1.000. A phylogenetic tree comprising four clusters was constructed using sequence variations of the 23 G. soja and 8 G. max resistant accessions. Five G. soja accessions in subcluster A2, and four G. soja accessions in cluster B were genetically distant from G. max genotypes. Eight resistance-associated SNPs in the three resistance genes formed nine haplotypes in total. G. soja resistant accessions had different haplotypes (H2, H4, H5, H6, H7, and H8) compared with those of G. max (H1, H3, and H9). These results provide vital information on the use of wild soybeans for broadening the genetic base of SCN resistance.
