Abstract
Objective: This study aims to explore the temporal trend of Low Anterior Resection Syndrome (LARS) and its symptoms after laparoscopic anterior resection for rectal cancer. Methods: A retrospective cohort study design was employed. The study included primary rectal (adenocarcinoma) cancer patients who underwent laparoscopic anterior resection at Tongji Hospital, Huazhong University of Science and Technology, between January 1, 2010, and December 31, 2020. Complete medical records and follow-up data at 3, 6, 9, 12, and 18 months postoperatively were available for all patients. A total of 1454 patients were included, of whom 1094 (75.2%) were aged ≤65 years, and 597 (41.1%) were females. Among them, 1040 cases (71.5%) had an anastomosis-to-anus distance of 0-5cm, and 86 cases (5.9%) received neoadjuvant treatment. All patients completed the Chinese version of the LARS questionnaire and their LARS occurrence and specific symptom information were recorded at 3, 6, 9, 12, and 18 months postoperatively. Considering past literature and clinical experience, further subgroup analyses were performed to explore the potential impact factors on severe LARS, including anastomosis level, preoperative neoadjuvant therapy, postoperative adjuvant therapy, and the presence of preventive stoma. Results: The occurrence rates of LARS at 3, 6, 9, 12, and 18 months postoperatively were 78.5% (1142/1454), 71.4% (1038/1454), 55.0% (799/1454), 45.7% (664/1454), and 45.7% (664/1454), respectively (χ2=546.180, P<0.001). No statistically significant difference was observed between the 12-month and 18-month time points (P>0.05). When compared with the symptoms at 3 months, the occurrence rates of gas incontinence [1.7% (24/1454) vs. 33.9% (493/1454)], liquid stool incontinence [3.9% (56/1454) vs. 41.9% (609/1454)], increased stool frequency [79.6% (1158/1454) vs. 95.9% (1395/1454)], stool clustering [74.3% (1081/1454) vs. 92.9% (1351/1454)], and stool urgency [46.5% (676/1454) vs. 78.7% (1144/1454)] in the LARS symptom spectrum were significantly alleviated at 12 months (all P<0.05) and remained stable beyond 12 months (all P>0.05). With the extension of postoperative time, the incidence rates of severe LARS exhibited a decreasing trend in different subgroups, of anastomosis level, preoperative neoadjuvant therapy, postoperative adjuvant therapy, and the presence of preventive stoma, and reached stability at 12 months postoperatively (all P>0.05). Conclusion: LARS and its specific symptom profile showed a trend of gradual improvement over time up to 1 year postoperatively, and stabilized after more than 1 year. Increased stool frequency and stool clustering are the most common features of abnormal bowel dys function, which improve slowly after surgery.

Abstract
In this research, the ultrasound-assisted extraction (UAE) conditions of the water-soluble polysaccharide (FCPS) from Ficus carica fruits were optimized using the response surface methodology. The optimal FCPS yield was 7.97 % achieved by conducting ultrasound-assisted extraction four times at a solid-liquid ratio of 1:20 (g/mL) and an ultrasound temperature of 70 °C. Then, the structure, antioxidant properties, hypoglycemic effects, and immunomodulatory activities of FCPS were evaluated. FCPS was characterized as irregular, rough-surfaced, flaky materials consisting of pyran-type polysaccharides with α- and β-glycosidic linkages, and composed of multiple monosaccharides and only one homogeneous concentrated polysaccharide component (FCPS1) with a molecular weight of 4.224 × 104 Da. The results suggested FCPS exhibited remarkable antioxidant activity in vitro, as evidenced by improved cell viability and reduced the reactive oxygen species (ROS) levels. Meanwhile, FCPS effectively improved liver-related insulin resistance by promoting glucose consumption in hepatocytes and activated the immune response through activation of murine bone marrow-derived dendritic cells (DCs) and upregulation of interleukin 6 (IL6) and interleukin 12 (IL-12) expression. The findings demonstrate the efficacy of the UAE technique in isolating FCPS with biological functionality and FCPS could potentially serve as a beneficial organic antioxidant source and functional food, carrying important implications for future studies.

Abstract
We evaluated the effects of supplementing bacterial direct-fed microbial (DFM) on performance, apparent total-tract digestibility, rumen fermentation, and immune parameters of lactating dairy cows. One hundred fourteen multiparous Holstein cows (41 ± 7 DIM) were used in a randomized complete block design with an experiment comprising 14 d of a covariate (pre-experimental sample and data collection) and 91 d of an experimental period. Cows were blocked based on energy-corrected milk (ECM) yield during the covariate period and the following treatments were randomly assigned within each block: (1) control (CON), corn silage-based total mixed ration without DFM; (2) PRO-A, basal diet top-dressed with a mixture of Lactobacillus animalis and Propionibacterium freudenreichii at 3 × 109 cfu/d; and 3) PRO-B, basal diet top-dressed with a mixture of L. animalis, P. freudenreichii, Bacillus subtilis, and Bacillus licheniformis at 11.8 × 109 cfu/d. Milk yield, dry matter intake (DMI), and body weight were measured daily, while milk samples for component analysis were taken on 2 consecutive days of each week of data collection. Feces, urine, rumen, and blood samples were taken during the covariate period, wk 4, 7, 10, and 13 for estimation of digestibility, N-partitioning, rumen fermentation, plasma nutrient status and immune parameters. Treatments had no effect on DMI and milk yield. Fat-corrected milk (3.5% FCM) and milk fat yield were improved with PRO-B, while milk fat percent and feed efficiency (ECM/DMI) tended to increase with PRO-B compared with PRO-A and CON. Crude fat digestibility was greater with PRO-B compared with CON. Feeding CON and PRO-A resulted in higher total volatile fatty acid concentration relative to PRO-B. Percentage of neutrophils tended to be reduced with PRO-A compared with CON and PRO-B. The mean fluorescence intensity (MFI) of anti-CD44 antibody on granulocytes tended to be higher in PRO-B compared with CON. The MFI of anti-CD62L antibody on CD8+ T cells was lower in PRO-A than PRO-B, with PRO-A also showing a tendency to be lower than CON. This study indicates the potential of DFM to improve fat digestibility with consequential improvement in fat corrected milk yield, feed efficiency and milk fat yield by lactating dairy cows. The study findings also indicate that dietary supplementation with DFM may augment immune parameters or activation of immune cells, including granulocytes and T cells; however, the overall effects on immune parameters are inconclusive.

Abstract
Introduction Aim: to investigate the effects of low sodium formula salt combined with the Chinese Modified Dietary Approaches to Stop Hypertension (DASH) diet on cerebrovascular function in patients with hypertension and type 2 diabetes. Methods: an eight-week single-arm trial was conducted in 66 patients with hypertension and type 2 diabetes to investigate effects of low sodium formula salt (potassium chloride 56 %, sodium chloride 23 %, 5 g/day) combined with Chinese Modified DASH diet on cerebrovascular function (measured by transcranial Doppler sonography), indicators of chronic diseases (blood pressure, blood glucose and blood lipids) and urinary excretion. The above indicators were performed before and after intervention. Results: fifty-nine subjects completed the study. Peak systolic velocity, mean flow velocity, end-diastolic velocity, pulsatility index and resistance index of internal cerebral artery and vertebral artery decreased significantly (p < 0.05); pulsatility index and resistance index of anterior cerebral artery and middle cerebral artery decreased significantly (p < 0.05); and end-diastolic velocity and pulsatility index of basilar artery decreased significantly (p < 0.05). Systolic blood pressure, diastolic blood pressure, fasting blood glucose and postprandial blood glucose decreased significantly (p < 0.001; p < 0.001; p < 0.001; p < 0.001). Blood pressure and blood glucose control rates increased significantly (p < 0.001). Conclusions: based on the study, 23 % low-sodium formula combined with CM-DASH diet pattern can improve cerebrovascular function in community patients with hypertension complicated with diabetes and has a good short-term benefit of blood pressure and glucose control.

Abstract
Introduction Background and purpose: the Dietary Approaches to Stop Hypertension (DASH) diet has multifunctional health benefits. We evaluated the effects of low-sodium salt applied to Chinese modified DASH diet on arterial stiffness in older patients with hypertension and type 2 diabetes. Methods: sixty-one older adults with hypertension and type 2 diabetes were randomly allocated to low sodium salt group (n = 31) or normal sodium salt group (n = 30). They were given the Chinese modified DASH diet plus low-sodium salt (52 % sodium chloride) or same diet plus regular salt (99 % sodium chloride) for eight weeks, respectively. Brachial and ankle pulse wave conduction velocity, ankle brachial index and atherosclerosis-related indices were measured at baseline and week 8. In addition, 24-hour urine and blood samples were measured at baseline, the 4th week and the end of the intervention. Results: as compared with the baseline, the low sodium salt group significantly decreased in ankle brachial index (-0.09 ± 0.11, p < 0.001) and brachial and ankle pulse wave conduction velocity (-133.07 ± 265.99 cm/s, p = 0.010) at week 8 while the normal sodium salt group only decreased significantly in ankle brachial index (-0.06 ± 0.12, p = 0.010) at week 8. Conclusion: the low-sodium salt applied to Chinese modified DASH diet may improve arterial stiffness in patients with hypertension and type 2 diabetes. Further research with an extended follow-up is needed.

Abstract
Background In this study, we aimed to explore the antihypertensive effect of 23 and 52% concentrations of low-sodium salt combined with the Chinese Modified Dietary Approaches to Stop Hypertension (CM-DASH) diet in patients with hypertension and type 2 diabetes. Methods We conducted a randomized controlled single-blind trial with a semi-open design. One hundred and thirty-two participants were randomly assigned into Group A (control group), Group B (52% low-sodium salt group), Group C (23% low-sodium salt group), and Group D (meal pack group) for 8 weeks of dietary intervention. All participants were followed weekly to collect data on blood pressure, salt use, and adverse events. Blood and 24-h urine samples were analyzed at baseline, 4 weeks, and the end of the intervention. Results At the end of the intervention, the mean blood pressure decreased significantly by 10.81/5.03 mmHg, 14.32/6.32 mmHg, 14.20/6.59 mmHg, and 19.06/7.82 mmHg in Groups A-D, respectively, compared with baseline (p < 0.001). Comparison between groups showed that the systolic blood pressure was lower in Groups C and D than in Groups A (-6.54 mmHg, -8.70 mmHg, p < 0.05) and B (-6.60 mmHg, -8.76 mmHg, p < 0.05), and the diastolic blood pressure was lower in Group D than in Group A (-5.17 mmHg, p = 0.006). The 24-h urinary Na+ and Na+/K+ values were significantly decreased in participants using low-sodium salt (p < 0.001). No serious adverse events occurred during the trial. Conclusion Our preliminary results suggest that 23 and 52% concentrations of low-sodium salt combined with the CM-DASH diet can effectively reduce sodium intake and increase potassium intake in patients with hypertension and type 2 diabetes mellitus, thus achieving "salt reduction" and attaining standard, smooth, comprehensive management of patients with hypertension and type 2 diabetes.

Abstract
OBJECTIVE To establish a scientific foundation for focused stroke prevention and treatment efforts by comprehending the risk variables connected to carotid plaque formation in adults over 40 who are at high risk of stroke in Yubei District, Chongqing, China. METHODS By comparing the differences in carotid plaque formation between people of different ages, smoking, blood pressure levels, low-density lipoprotein levels, and glycosylated hemoglobin levels, questionnaires and physical exams were performed on a random sample of permanent residents aged 40 years in three communities in Yubei District, Chongqing, China. The goal was to investigate the risk factors associated with carotid plaque formation in the population. RESULTS The incidence of carotid plaque gradually increased in the study population as age, blood pressure, low-density lipoprotein, and glycosylated hemoglobin levels increased. The difference in carotid plaque formation between people of different ages, smoking, blood pressure levels, low-density lipoprotein levels, and glycosylated hemoglobin levels was statistically significant (p<0.05). The findings of the multifactorial logistic regression analysis revealed that there was a tendency for the risk of developing carotid plaque to rise with age; the risk of developing carotid plaque in hypertensive patients was (OR=1.41,95% CI: 1.03-1.93); the population of smokers was (OR=2.01,95%CI:1.33-3.05); the low-density lipoprotein cholesterol borderline increased group was (OR=1.94,95%CI:1.03-3.66); the low-density lipoprotein cholesterol elevated group was (OR=2.71,95%CI: 1.26-5.84); glycosylated hemoglobin elevated group was (OR=1.40,95%CI: 1.01-1.94) (p<0.05). CONCLUSION Age, smoking, blood pressure, low-density lipoprotein, and glycosylated hemoglobin are all associated with carotid plaque formation in those over 40 who are at high risk of stroke. As a result, health education for residents needs to be strengthened to raise knowledge of carotid plaque prevention.

Abstract
Introduction Capparis spinosa L. fruits as edible and medicinal plant, has anti-inflammatory activities. The different morphological characteristics of C. spinosa fruits from Ili, Turpan, and Karamay may affect their anti-inflammatory components and functions. Methods The anti-inflammatory activity of C. spinosa fruit was assessed using an LPS-induced inflammatory cell model. Furthermore, the differences in anti-inflammatory compounds were analyzed by metabolome and RNA-seq. Additionally, the anti-inflammatory mechanism was elucidated using network pharmacology. Results In the study, we found that the 95% ethanol extracts (CSE) obtained from the three kinds of fruits showed remarkable anti-inflammatory effects both in vivo and in vitro. However, the CSE derived from Ili fruits significantly reduced CD86 levels on DCs. As a result of metabolomic analysis, the metabolic profiles of Ili fruits differed significantly from those of the other two habitats, which were consistent with transcriptome analysis. A total of 15 compounds exhibiting anti-inflammatory activity were subjected to screening, revealing a greater accumulation of flavonoids in the Turpan and Karamay districts. Notably, phenolic compounds were identified as the principal anti-inflammatory components in C. spinosa. Conclusion There were significant differences in the morphology, metabolites, transcriptional levels, and anti-inflammatory activity of C. spinosa from the three districts.

Abstract
Objective: To investigate the clinical characteristics of abnormal liver function in patients with advanced esophageal squamous carcinoma treated with programmed death-1 (PD-1) antibody SHR-1210 alone or in combination with apatinib and chemotherapy. Methods: Clinical data of 73 patients with esophageal squamous carcinoma from 2 prospective clinical studies conducted at the Cancer Hospital Chinese Academy of Medical Sciences from May 11, 2016, to November 19, 2019, were analyzed, and logistic regression analysis was used for the analysis of influencing factors. Results: Of the 73 patients, 35 had abnormal liver function. 13 of the 43 patients treated with PD-1 antibody monotherapy (PD-1 monotherapy group) had abnormal liver function, and the median time to first abnormal liver function was 55 days. Of the 30 patients treated with PD-1 antibody in combination with apatinib and chemotherapy (PD-1 combination group), 22 had abnormal liver function, and the median time to first abnormal liver function was 41 days. Of the 35 patients with abnormal liver function, 2 had clinical symptoms, including malaise and loss of appetite, and 1 had jaundice. 28 of the 35 patients with abnormal liver function returned to normal and 7 improved to grade 1, and none of the patients had serious life-threatening or fatal liver function abnormalities. Combination therapy was a risk factor for patients to develop abnormal liver function (P=0.007). Conclusions: Most of the liver function abnormalities that occur during treatment with PD-1 antibody SHR-1210 alone or in combination with apatinib and chemotherapy are mild, and liver function can return to normal or improve with symptomatic treatment. For patients who receive PD-1 antibody in combination with targeted therapy and chemotherapy and have a history of long-term previous smoking, alcohol consumption and hepatitis B virus infection, liver function should be monitored and actively managed in a timely manner.

Abstract
HYPOTHESIS Horseshoe vortices are known to emerge around large-scale obstacles, such as bridge pillars, due to an inertia-driven adverse pressure gradient forming on the upstream-side of the obstacle. We contend that a similar flow structure can arise in thin-film Stokes flow around micro-obstacles, such as used in textured surfaces to improve wettability. This could be exploited to enhance mixing in microfluidic devices, typically limited to creeping-flow regimes. EXPERIMENTS Numerical simulations based on the Navier-Stokes equations are carried out to elucidate the flow structure associated with the wetting dynamics of a liquid film spreading around a 50 μm diameter micro-pillar. The employed multiphase solver, which is based on the volume of fluid method, accurately reproduces the wetting dynamics observed in current and previous (Mu et al., Langmuir, 2019) experiments. FINDINGS The flow structure within the liquid meniscus forming at the foot of the micro-pillar evinces a horseshoe vortex wrapping around the obstacle, notwithstanding that the Reynolds number in our system is extremely low. Here, the adverse pressure gradient driving flow reversal near the bounding wall is caused by capillarity instead of inertia. The horseshoe vortex is entangled with other vortical structures, leading to an intricate flow system with high-potential mixing capabilities.

Abstract
In order to characterize the chloroplast genome and phylogenetic relationships of Isopyrum anemonoides, we performed Illumina Hiseq high-throughput sequencing to sequence the complete chloroplast genome of this plant and constructed a whole-genome map based on contig assembly and annotation. The chloroplast genome of I. anemonoides is 161 034 bp in length and has a typical tetrad structure, comprising 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. The genome also contains a total of 44 dispersed repeat sequences and 47 simple sequence repeats. Among the genome's 53 678 codons, the largest proportion are leucine-encoding codons (5 251), whereas the smallest proportion encode tryptophan (712). Colinear analysis revealed an absence of inversions and rearrangements between I. anemonoides and related species at the chloroplast genome level. Whereas phylogenetic analysis indicated that I. anemonoides did not cluster in a clade with I. manshuricum, it did show a very close phylogenetic relationship with Paraquilegia microphylla. The findings of this study provide basic data that will contribute to further species identification and phylogenetic study of the genus Isopyrum.

Abstract
Abstract
Study question
Does high serum uric acid (SUA) level affect the reproductive outcomes in women with polycystic ovary syndrome (PCOS) undergoing in-vitro fertilization (IVF)?
Summary answer
Elevated SUA is associated with decreased live birth rate, biochemical pregnancy rate and clinical pregnancy rate, and increased miscarriage rate in women with PCOS.
What is known already
SUA levelsand the prevalence of hyperuricemia (25.48%) are both significantly higher in women with PCOS than in women without PCOS (8.74%). SUA levels also can be used as a predictor of pregnancy complications (gestational diabetes mellitus and hypertensive disorders of pregnancy) and adverse foetal outcomes (preterm birth and low birth weight).
Study design, size, duration
This retrospective cohort study was conducted ininfertile women with PCOS between September 2012 and December 2019.
Participants/materials, setting, methods
A total of 1,032 infertile PCOS women undergoing their first IVF/ICSI cycle were observed. Data of reproductive outcomes including live birth rate, biochemical pregnancy rate, clinical pregnancy rate, and miscarriage rate were analyzed according to the quartile groups of SUA levels.
Main results and the role of chance
In quartiles of SUA levels, there was a significant decreasing trend in live birth rate from the lowest quartile (Q1: 34.5%) to the highest (Q4: 19.2%) (Pfor trend <0.001). Notably, the miscarriage rate in Q4 was significantly higher than that in the other 3 quartiles (all P values < 0.05). From Q1 to Q4, the incidence of miscarriage dramatically increased from 15.5% to 31.0% (Pfor trend <0.05). In addition, the biochemical pregnancy rate and clinical pregnancy rate decreased significantly from the lowest quartile to the highest (Pfor trend <0.05). With the first quartile of uric acid as the reference group, the logistic regression analysis showed that in both unadjusted and adjusted models, elevated SUA level was associated with significantly lower probabilities of live birth, biochemical pregnancy, and clinical pregnancy, and a higher risk of miscarriage in a linear fashion (all Pfor trend< 0.05).
Limitations, reasons for caution
This study is limited by its retrospective design. It was difficult to ensure consistency in clinical practice among the physicians.
Wider implications of the findings
Our study suggeststhat clinical physicians need to pay close attention to PCOS women with high SUA levelsbefore IVF treatment. Prospective studies to determine an appropriate range of lower-SUA levels prior to treatment is necessary to support our findings.

Abstract
Objectives: to evaluate the effect of sodium reduction based on a modified DASH diet on blood pressure in hypertensive patients with type 2 diabetes. Material and methods: sixty-one hypertensive patients with type 2 diabetes were selected from the community and randomly allocated to a common salt group and low sodium salt group receiving the 8-week dietary intervention, in which weeks 1-2 was the dietary guidance phase, weeks 3-4 was the centralized feeding phase, and weeks 5-8 was the home medical care phase. Participants were followed up in the hospital once a week to collect information on outpatient blood pressure, salt, and drug use. Physical examinations were conducted at 4 weeks and the end of the intervention, as well as at baseline. Results: after the intervention, the blood pressure of both the low sodium group (SBP: -14.32 mmHg, p < 0.001; DBP: -6.32mmHg, p < 0.001) and the common salt group (SBP: -10.98 mmHg, p < 0.001; DBP: -5.24 mmHg, p = 0.001) decreased significantly with a more pronounced decrease in the low sodium group but no statistically significant differences between the two groups (SBP: -0.28 mmHg, p = 0.929; DBP: -3.32 mmHg, p = 0.093). At the end of the intervention, sodium intake was significantly decreased, but potassium intake was increased in the low sodium group (p < 0.05); however, the common salt group had no significant change. Conclusion: reducing sodium intake based on the modified DASH diet had a good effect on systolic and diastolic blood pressure in hypertensive patients with type 2 diabetes. Sodium reduction based on the modified DASH diet is safe and effective, and can be used as a guide for healthy living in hypertensive patients.

Abstract
OBJECTIVE Excessive salt intake is currently the foremost universal risk factor for controllable chronic disease. This study evaluated the short-term effects of a modest salt intake reduction combined with the Chinese Modified Dietary Approaches to Stop Hypertension (CM-DASH) diet on sodium and potassium intake, mean arterial pressure (MAP), and pulse pressure (PP) in hypertensive patients with type II diabetes. METHODS Sixty-one participants were randomized to the intervention group (52% low-sodium salt and DASH) and control group (normal salt and DASH). An 8-week dietary intervention was applied. Daily salt intake, blood pressure (BP), and drug use were recorded every week. Twenty-four-hour urine, casual urine, and blood samples were measured at baseline, the 4th week, and the end of the intervention. RESULTS Fifty-nine patients (25 men) completed the entire study. Sodium intake decreased by 1259.66 (792.76, 1726.56)/705.80 (149.21, 1262.39) mg/day after 4 weeks (intervention: P < .001; control: P = .015). Potassium intake increased by 641.14 (73.31, 1208.96)/43.43 (-259.66, 346.53) mg/day (intervention: P = .028); MAP decreased by 9.06 (6.69, 11.43)/7.16 (4.03, 10.28) mmHg (both: P < .001); PP decreased by 7.97 (3.05, 12.88)/5.74 (2.55,8.94) mmHg (intervention: P = .002; control: P = .001) after 8 weeks. However, the difference between the two groups was not statistically significant. CONCLUSION Modest salt reduction and the CM-DASH diet for hypertensive patients with type II diabetes can achieve short-term salt reduction effects. The effect on changing salt-eating habits needs to be investigated with an extended follow-up.

Abstract
BACKGROUND The objective was to determine how molasses and Lactobacillus plantarum affect chemical composition, fermentation quality, aerobic stability, and the microbial community of an ensiled mixture of amaranth (Amaranthus hypochondriaus, AF) and rice straw. Treatments were control (C, no addition), L. plantarum (L; 2 × 105 cfu g-1 fresh weight), molasses (M; 40 g kg-1 fresh matter), and their combination (LM). All treatments were ensiled for 1, 3, 5, 7, and 30 days. RESULTS All additives improved fermentation quality with greater lactic acid (LA), acetic acid, and lower pH than C silage over the ensiling period. The LM silage combination optimized fermentability, manifested as greater LA contents and a more rapid pH reduction during the first 7 days of ensiling than L or M silages. After 30 days of ensiling, inoculant L. plantarum increased Lactobacillus abundance and reduced bacterial diversity and Enterobacteriaceae abundance compared with silage treated with molasses. Molasses addition reduced the relative concentration of structural carbohydrates (neutral and acid detergent fiber, and hemicellulose) after 30 days of ensiling. Finally, there was spoilage after 2 days and 4 days of aerobic exposure in C and LM silages respectively, whereas L silage had not spoiled after 4 days. CONCLUSIONS Although the combination of L. plantarum and molasses further optimized fermentation characteristics, L silage had better aerobic stability. © 2021 Society of Chemical Industry.

Abstract
The neutral particles generated by charge exchange reactions can play an important role in erosion of first wall materials in fusion devices. In order to measure the flux and energy of neutral particles to the first wall, a low-energy neutral particle analyzer (LENPA) based on the time-of-flight method has been developed and successfully applied on the Experimental Advanced Superconducting Tokamak (EAST)' to measure the neutrals with an energy of 20-3000 eV. The LENPA works in the counting mode, and the signal of photons is used as the reference for the flight time of neutrals. The energy spectrum of low-energy neutral particles on EAST has been obtained for the first time. The new diagnostics can help in understanding the neutral particle generation and deposition on the first wall materials in tokamaks under different plasma conditions.

Abstract
Men who have sex with men (MSM) are at risk of contracting the hepatitis C virus (HCV). Previous studies have documented low uptake of sexually transmitted disease (STD) prevention and health services among Chinese MSM. We carried out qualitative research among MSM in Southwest China. By taking the Health Brief Model (HBM) as a framework, we aimed to determine the underlying factors related to use of HCV health intervention services among MSM. From May to July 2018, we conducted in-depth interviews in Southwest China with 20 participants. Our research revealed that a lack of knowledge about HCV prevention was the main reason why MSM failed to perceive their susceptibility to HCV and had low motivation to seek preventive services. Poor service accessibility and unpleasant experiences seeing doctors also exerted negative influences on health care-seeking behaviour in MSM. More trust and understanding needs to be built between health providers and MSM. Protection of privacy for MSM should be guaranteed in the delivery of health interventions. In addition, the interviewees showed refusal to engage with health interventions being specifically targeted at MSM, which would create a sense of being 'labelled'. Tailored health interventions may overemphasise their sexuality, segregate them from heterosexuals, and make them feel alienated. Therefore, we speculate that differential treatment may be an obstacle for MSM to become involved in health interventions.

Abstract
This study aimed to examine the effect of eicosapentaenoic acid (EPA) on skeletal muscle hypertrophy induced by muscle overload and the associated intracellular signaling pathways. Male C57BL/6J mice were randomly assigned to oral treatment with either EPA or corn oil for 6 weeks. After 4 weeks of treatment, the gastrocnemius muscle of the right hindlimb was surgically removed to overload the plantaris and soleus muscles for 1 or 2 weeks. We examined the effect of EPA on the signaling pathway associated with protein synthesis using the soleus muscles. According to our analysis of the compensatory muscle growth, EPA administration enhanced hypertrophy of the soleus muscle but not hypertrophy of the plantaris muscle. Nevertheless, EPA administration did not enhance the expression or phosphorylation of Akt, mechanistic target of rapamycin (mTOR), or S6 kinase (S6K) in the soleus muscle. In conclusion, EPA enhances skeletal muscle hypertrophy, which can be independent of changes in the AKT-mTOR-S6K pathway.

Abstract
Aim to compare the home blood pressure monitoring (HBPM) and visit blood pressure monitoring in a clinical phase I single-arm pilot trial. The 18% sodium substitute salt was used in 43 hypertensives for 8 weeks, and visited once a week, while weekly visit blood (VBP) pressure, daily home blood pressure (HBP) and urine test results before and after intervention were collected. 43 hypertensive patients were recruited, 4 were lost. And enrolled 39 patients for analysis. The VBP were lower than morning HBP and night HBP (P < 0.05). And VBP was good correlated with morning BP (SBP: r = 0.692, P < 0.001, DBP: r = 0.789, P < 0.001) and night BP (SBP: r = 0.571, P < 0.001, DBP: r = 0.738, P < 0.001). The results of mixed linear model analysis showed that patients' visit SBP (- 11.4 mmHg, 95% CI: - 17.0 to - 5.7, P < 0.001), morning home SBP (- 10.0 mmHg, 95% CI: - 16.4 to - 3.6, P = 0.003) and night home SBP (- 10.2 mmHg, 95% CI: - 15.8 to - 4.6, P = 0.001) decreased significantly, after intervention. Both HBP and VBP showed that 18% substitute salt intervention could decrease the blood pressure of hypertensives. Medication led to VBP lower than HBP, but the two still had a good correlation.Trial registration: NCT03226327. Registered 21 July 2017-Retrospectively registered, http://www.clinicaltrials.gov .

Abstract
Abstract
Background
With demographic and epidemiologic transitions, China has become home to the greatest number of obese individuals in the world. Effective policy intervention requires a contemporary assessment of obesity across broad socio-demographic subgroups.
Purpose
We aim to assess the prevalence of overall and abdominal obesity by socio-demographic characteristics and the associations of these characteristics with obesity in China.
Methods
Using the data of 2.7-million community-dwelling participants aged 35–75 years in the China PEACE Million Persons Project, a nationwide cross-sectional screening project from 2014 to 2018, we calculated the prevalence of overall and abdominal obesity based on national guideline definitions (body mass index ≥28 kg/m2, waist circumference ≥85/90 cm for women/men). We examined 12 available socio-demographic variables that are potentially associated with obesity, in addition to self-reported co-morbidities, and quantified the associations of these socio-demographic characteristics with obesity using multivariable mixed models.
Results
The prevalence of overall and abdominal obesity were 15.8% and 37.6% in women and 15.0% and 36.3% in men (Figure). Compared to individuals with normal weight, those with overall obesity had a higher prevalence of hypertension, dyslipidemia, and diabetes (in women: by 30.4, 16.1, and 6.0 percent points; in men, by 29.9, 31.2, and 5.8 percent points). A similar pattern was observed with abdominal obesity. In women, those aged 55–64 years constituted the largest age group with overall and abdominal obesity (33.7% and 35.0%), while in men, those aged 45–54 and 55–64 years constituted the largest age group with overall obesity (30.4%) and abdominal obesity (30.5%), respectively. Older women were at substantially higher risk for obesity (e.g., adjusted relative risk [95% CI] of women aged 65–75 vs. 35–44 years: 1.29 [1.27–1.31] for overall obesity and 1.76 [1.74–1.77] for abdominal obesity) while older men were not. Higher education was associated with lower risk in women (e.g., those with college or university education vs. less than primary school: 0.47 [0.46–0.48] for overall obesity and 0.61 [0.60–0.62] for abdominal obesity) but higher risk in men (1.07 [1.05–1.10] and 1.17 [1.16–1.19]). In both women and men, current smoking was associated with lower risk for obesity, and current drinking was associated with higher risk, but the magnitude of associations was smaller in women than men.
Conclusions
In China, over one in seven individuals meet criteria for overall obesity, and one in three for abdominal obesity. Wide variation exists across socio-demographic subgroups. The associations of age and education with obesity are significant and differ by sex. Understanding obesity in contemporary China has broad domestic policy implications and provides a valuable international reference.

Abstract
Abstract
Background
While cardiovascular mortality in women has exceeded those in men, women continue to be underrepresented in cardiovascular clinical trials. Further, preclinical experiments are predominantly conducted in male animals, rendering sex-specific variables contributing to cardiovascular disease largely unknown. As age and menopause remain to be key risk factors for cardiovascular disease in women, the aim of this study was to identify key variables of cardiac remodelling in the aging female and male heart, as well as to assess effects of sex hormone deprivation on left ventricular (LV) morphology, LV function and cardiac sympathetic activity.
Materials and methods
Gonadectomized and sham-operated FVB/N mice of both sexes were subjected to positron emission tomography (PET) and cardiac magnetic resonance (CMR) imaging at the age of 4 (young cohort) and 20 (aged cohort) months (total n=123, 55% females). Following tail-vein injection of [11C]meta-hydroxynorephedrine ([11C]mHED), a widely used PET probe in preclinical and clinical assessment of cardiac sympathetic integrity, animals were scanned and cardiac sympathetic outflow was derived from myocardial [11C]mHED uptake. Cardiac parameters including LV volumes and left ventricular ejection fraction (LVEF) were obtained from electrocardiogram (ECG)-gated CMR imaging.
Results and discussion
A significant increase of LVEF was observed in aging females (p=0.012, Figure 1), but not in males. The latter was not associated with a higher cardiac output, and was a consequence of reduced LV end-systolic volumes (p=0.008), unveiling a substantial reduction of size in the aging female heart. As this age-dependent observation was not present in gonadectomized animals (p=0.414), the lack of growth-stimulating estrogen might account for reduction of cardiac size in aging females. Thus, despite a significantly heightened body weight, female heart size is reduced with age. Accordingly, sufficient cardiac output was maintained via increased heart rate (p=0.005) and cardiac sympathetic activity (p=0.040, Figure 1). Gonadectomy accelerated age-dependent changes in LV morphology and function in female mice. While sex hormone deprivation blunted cardiac sympathetic activity and norepinephrine levels in male mice, an opposite trend was observed in females.
Conclusion
Despite increasing body weight with age, aged female and male hearts maintain a stable circulatory blood supply, however, by distinct mechanisms. While the “shrinking” female heart requires an increased heart rate and cardiac sympathetic activity to compensate for smaller ventricular volumes, aging males maintain cardiac size. Importantly, sex hormone deprivation at a young age accelerates age-dependent changes in LV morphology and function in female mice, but not in male mice. The increased sympathetic activity reflects a higher stress level in aged females that might expose them to a higher cardiac vulnerability at postmenopausal age.

Abstract
A quartz crystal microbalance (QMB) diagnostic system has been established in Experimental Advanced Superconducting Tokamak (EAST) for real-time and in situ measurements of erosion and deposition rates of plasma-facing materials at the first wall. A ∼70 nm aluminum (Al) film has been coated on the QMB crystal surface to measure the erosion rate by charge exchange neutral particles. Dual sensors of the QMB system have been used with a closed sensor for reference. The stability and light sensitivity of the QMB system have been tested in the lab, demonstrating its feasibility on the application of EAST experiments. The QMB system with cooling water has been successfully applied in the 2018 EAST campaign. The net erosion thickness measured by the QMB has been well validated by thickness measurements using the Rutherford backscattering spectrometry. The developed QMB systems can help us to understand the physics processes of material erosion and deposition at main chamber walls for long pulse operations in EAST.

Abstract
Background:After the introduction of treat-to-target strategy in systemic lupus erythematosus (SLE), Lupus Low Disease Activity State (LLDAS) and definitions of remission in SLE (DORIS) were developed and validated. Several studies had demonstrated that the achievement and maintenance of LLDAS or DORIS was associated with good prognosis.Objectives:To evaluate the attainability of LLDAS and DORIS in a treatment-naïve cohort of SLE.Methods:LDAS5 was defined as LLDAS with a prednisone dose ≤5 mg/d. There were 4 definitions in DORIS: clinical remission on treatment (RONT), complete RONT, clinical remission off treatment (ROFT) and complete ROFT. The treatment-naïve patients from Peking University First Hospital SLE cohort were enrolled. The time to each state and their annual cumulative probabilities were estimated by Kaplan-Meier approach. The frequencies of patients who achieved each component of LLDAS or DORIS during follow-up were determined.Results:A total of 218 treatment-naïve patients were included, with a median follow-up of 4.48 years. Respectively, 190 (87.2%), 160 (73.4%), 148 (67.9%), 94 (43.1%), 23 (10.6%) and 18 (8.3%) patients achieved LLDAS, LLDAS5, clinical RONT, complete RONT, clinical ROFT and complete ROFT at least once during the follow-up time. The median time to LLDAS, LLDAS5, clinical RONT and complete RONT were 1.4, 2.3, 2.6 and 4.7 years, respectively.Table 1.Frequencies, time to achieve and annual cumulative probabilities of each state by Kaplan-Meier approachStatesAchieved patientsNumber (%)Time to achieve(years)Cumulative probabilities of achievement (%)Year 1Year 2Year 3Year 4Year 5LLDAS190 (87.2)1.418.869.786.789.192.6LLDAS5160 (73.4)2.36.940.763.376.082.3Clinical RONT148 (67.9)2.65.536.156.168.876.6Complete RONT94 (43.1)4.74.122.637.545.350.4Clinical ROFT23 (10.6)NA1.42.95.46.710.6Complete ROFT18 (8.3)NA0.92.54.84.88.8Table 2.Patients who achieved each component of LLDAS or DORIS during follow-upComponentsNumber (%)SLEDAI-2K ≤4, with no activity in major organ systems (renal, central nervous system, cardiopulmonary, vasculitis, fever), and no haemolytic anaemia or gastrointestinal active213 (97.7)Clinical SLEDAI-2K =0210 (96.3)PGA ≤1217 (99.5)PGA <0.5199 (91.3)Serology (anti-dsDNA and complement) negative148 (67.9)Prednisone dose ≤7.5 mg/day201 (92.2)Prednisone dose ≤5 mg/day171 (78.4)No prednisone dose40 (18.3)No prednisone dose and Immunosuppressants32 (14.7)Conclusion:Our data confirmed that LLDAS is an attainable early treatment target for SLE.

Abstract
Background:Patients with systemic lupus erythematosus (SLE) who achieved the clinical state as serologically active clinically quiescent (SACQ). It appears to account for 6–12% of all patients with SLE, but there is disagreement about whether such patients are indeed clinically stable [1-3], especially in Chinese patients. And there is no conclusion as to what kind of treatment should be taken for such patients.Objectives:To clarify the frequency and outcome of SACQ patients in lupus. And to identify factors associated with the flare of disease.Methods:Clinical data of patients diagnosed as SLE and followed in Peking University First Hospital from 2009 to 2015 were retrospectively reviewed. 682 patients with systemic lupus erythematosus who were followed up for more than 6 months at Peking University First Hospital from January 2007 to December 2015 were summarized. SACQ was defined as an at least a 6-month period with persistent serologic activity and without clinical activity and could be taking a daily dose of prednisone or equivalent less than 7.5 mg. Serologically quiescent clinically quiescent (SQCQ) patients and serologically active clinically active (SACA) patients served as control groups. Data including demographics, initial symptoms, duration to SACQ, treatments before and after SACQ, and characteristics of the flare group were analyzed.Results:Of the 682 patients, 170 were SACQ patients (24.9%), 187 were SQCQ patients, and 325 were SACA patients (47.7%). SQCQ patients (38.61±15.08 years old) were older at study start than SACQ patients (38.61±15.08 years vs. 32.09±14.35 years, p<0.001), but there was no significant difference between that of SACQ and SACA patients. 56 of the 170 SACQ patients (32.9%) experienced flare. Corticosteroids (OR 1.317, 95% CI 1.131 to 1.534; p<0.001) was an independent risk factor for flare, while antimalarials (OR 0.265, 95% CI 0.118 to 0.599; p=0.001) and immunosuppressants (OR 0.316, 95% CI 0.149 to 0.670; p=0.003) were protective factors.Conclusion:About one third of SLE patients with SACQ experience flare, more than that of patients with SQCQ. Thus, approach to prevent relapse in SACQ patient is required. Maintenance therapy of hydroxychloroquine and immunosuppressant agents may be protective and beneficial treatment strategy in these patients need further investigation.References:[1]Gladman DD, Urowitz MB, Keystone EC.

Abstract
Background:As a consensus-based definition of minimally acceptable disease activity in systemic lupus erythematosus (SLE), Lupus Low Disease Activity State (LLDAS) has been well-validated and widely accepted. However, no data about the time to LLDAS in Asian ethnicity has been reported so far.Objectives:To estimate the time to LLDAS and the predictors of time to LLDAS in our prospective observational cohort of Chinese patients with SLE.Methods:Patients were from Peking University First Hospital SLE cohort and those having not fulfilled LLDAS at enrolment were included in this study. The time to LLDAS and annual cumulative probabilities of LLDAS achievement were estimated by the Kaplan-Meier approach. The predictors of time to LLDAS were identified by univariate and multivariable Cox proportional hazards.Results:A total of 574 patients with SLE were included and 435 (75.8%) of them achieved LLDAS during a median 4.2 years of follow-up. The median time to LLDAS was 19.0 months and the cumulative probabilities at 1, 2, 3, 5 and 10 years were 19.8%, 57.6%, 72.0%, 85.1% and 98.0%, respectively. In multivariable Cox models, older age at disease onset, treatment-naïve and hydroxychloroquine prescription were found to be independent predictors of shorter time to LLDAS, after adjusted by daily prednisone dose, SLE Disease Activity Index 2000 and physician’s global assessment. Finally, we developed a matrix model based on the identified independent predictors to present the time to LLDAS in patients with respective characteristics.Conclusion:Our study proved that LLDAS is attainable as an early treatment target for SLE in Chinese patients. The older age at disease onset, treatment-naïve and hydroxychloroquine prescription were independent predictors of shorter time to LLDAS.References:[1]Franklyn K, Lau CS, Navarra SV, Louthrenoo W, Lateef A, Hamijoyo L, Wahono CS, Chen SL, Jin O, Morton S, Hoi A, Huq M, Nikpour M, Morand EF; Asia-Pacific Lupus Collaboration.

Abstract
OBJECTIVES To understand the possible effect of a novel salt substitute with very low sodium in reducing blood pressure, salt intake and use of anti-hypertensive medications among patients on regular medications, to inform the future randomized trials. DESIGN Single-arm pilot trial. SETTING A community health service center in Chongqing, China. PARTICIPANTS A total of 43 patients with hypertension taking anti-hypertensive medications regularly. INTERVENTION Patients received the salt substitute with 18% sodium chloride for 8 weeks. MAIN OUTCOME MEASURES Patients were followed up weekly for the use of antihypertensive medications and measurements of blood pressure. We collected 24-h urine before and after the trial to measure sodium and potassium intake. RESULTS Among 39 patients who completed the 8 weeks' intervention, 30.8% patients stopped or reduced anti-hypertensive medications during the trial. For patients that stopped or reduced medication, the mean SBP and DBP before intervention were 122.1 ± 9.6 and 68.9 ± 9.4 mm Hg and both did not increase after intervention (SBP change: 2.8 mm Hg (-5.1, 10.8), P = .48; DBP change: 1.8 mm Hg (-2.2, 5.7), P = .38). For the rest patients, the mean SBP and DBP before intervention were 141.6 ± 16.9 and 74.6 ± 6.6 mm Hg but reduced significantly after the intervention (SBP change: -16.0 mm Hg (-21.3, -10.6), P < .001; DBP change: -5.5 mm Hg (-8.1, -2.9), P < .001). The 24-h urine sodium decreased (P < .001) and potassium increased (P < .001) among all patients. No severe adverse events were reported. CONCLUSIONS The novel salt substitute showed potential in reducing blood pressure and use of antihypertensive medications. Further randomized double-blind controlled trial is warranted to validate these findings.Clinical Trial Registration-URL:http://www.clinicaltrials.gov. Unique identifier: NCT03226327.

Abstract
OBJECTIVE To evaluate the feasibility and effectiveness of the totally extraperitoneal renal autotransplantation with boari flap-pelvis anastomosis in the treatment of upper urinary tract urothelial carcinoma (UTUC), and to review the experience of renal autotransplantation for UTUC treatment. METHODS One case of applying the totally extraperitoneal renal autotransplantation with boari flap-pelvis anastomosis to the UTUC treatment was reported, and related literature was reviewed. The patient was a sixty-four-year old man who received right radical nephroureterectomy for right ureteral carcinoma 1 year before and diagnosed as left ureteral carcinoma(G2, high grade) this time. In order to preserve his renal function and avoid the shortness of common kidney-sparing surgery, a totally extraperitoneal procedure, including retroperitoneoscopic nephrectomy, ureterectomy, renal autotransplantation and Boari flap-pelvis anastomosis, was performed to the patient. RESULTS The operation was completed successfully without perioperative complications. The renal function recovered to preoperative level within 1 week. No deterioration of renal function during the follow-up and no tumor recurrence was observed under cystoscopy at the 3-month postoperative consult. CONCLUSION The totally extraperitoneal renal autotransplantation with Boari flap-pelvis anastomosis is a feasible and effective treatment for UTUC. The innovative procedure has several advantages compared to the former ones. The extraperitoneal procedure results in significantly less pain, shorter hospital stay, decreased overall time to recovery and lower bowel complications risk without warm ischemia time extension. Meanwhile, the Boari flap-pelvis anastomosis simplifies the follow -up protocols and creates an easy route for cystoscopy and topical therapy. From the systematic clinical analysis, as well as the related literature review, it's been concluded that the renal autotransplantation can be a reasonable option for the patients who have UTUC in solitary kidney or have bilateral UTUC. This type of treatment possesses advantages of preservation of renal function and total resection of malignant lesions. But long-term data and large cohort study on renal function or tumor recurrence are still absent which will be necessary to confirm the advantages of this approach.

Abstract
PURPOSE The effects of adipose insulin resistance on cardiovascular risk factors in polycystic ovary syndrome (PCOS) remain largely unknown. We aimed to investigate associations between adipose insulin resistance and cardiovascular risk factors in PCOS. METHODS A total of 207 PCOS and 47 non-PCOS women were recruited from a large reproductive medicine center in this cross-sectional study. The PCOS diagnosis was based on the Rotterdam Criteria. The subjects received a standard oral glucose tolerance test. Adipose insulin resistance was evaluated using a validated index (adipose-IR = fasting insulin × free fatty acid concentrations). RESULTS The women with PCOS showed a higher adipose-IR index, and the adipose-IR index was tightly associated with the blood pressure, glucose and lipid parameters. A total of 98.0% of the women with PCOS in the highest adipose-IR quartile showed cardiovascular risk factors (obesity, hypertension, glucose intolerance or dyslipidemia), and this percentage was significantly higher than the percentage of those in the lowest quartile (32.7%). In addition, the percentages of women with three (31.4%) and four (13.7%) cardiovascular risk factors were significantly elevated in the highest adipose-IR quartile. The multivariable logistic regression analysis indicated that each 1-SD increment in the adipose-IR index resulted in higher risks of obesity (OR = 3.18, 95% CI = 2.12-4.76), hypertension (OR = 1.89, 95% CI = 1.31-2.73), glucose intolerance (OR = 2.45, 95% CI = 1.73-3.48), and dyslipidemia (OR = 2.18, 95% CI = 1.57-3.01). The C-reactive protein (CRP) level was positively associated with the adipose-IR index in women with PCOS (r = 0.45, P < 0.001). CONCLUSIONS The adipose-IR index was associated with cardiovascular risk factors in women with PCOS. Chronic inflammation may induce insulin resistance in the adipose tissue of women with PCOS.

Abstract
Cancer stem cells (CSCs) are inherently resistant to chemotherapy, and CSCs in chemotherapy-failed recurrent tumors are enriched; however, the cellular origin of chemotherapy-induced CSC enrichment remains unclear. Communication with stromal fibroblasts may induce cancer cell dedifferentiation into CSCs through secreted factors. We recently demonstrated that fibroblast-derived exosomes promote chemoresistance in colorectal cancer (CRC). Here, we report that fibroblasts confer CRC chemoresistance via exosome-induced reprogramming (dedifferentiation) of bulk CRC cells to phenotypic and functional CSCs. At the molecular level, we provided evidence that the major reprogramming regulators in fibroblast-exosomes are Wnts. Exosomal Wnts were found to increase Wnt activity and drug resistance in differentiated CRC cells, and inhibiting Wnt release diminished this effect in vitro and in vivo. Together, our results indicate that exosomal Wnts derived from fibroblasts could induce the dedifferentiation of cancer cells to promote chemoresistance in CRC, and suggest that interfering with exosomal Wnt signaling may help to improve chemosensitivity and the therapeutic window.

Abstract
To understand the erosion effect of neutral particles on the first wall, a low energy neutral particle analyzer (LENPA), based on the time-of-flight method, has been developed for the Experimental Advanced Superconducting Tokamak (EAST). The LENPA to be installed in the EAST mid-plane mainly consists of a chopper sub-system, a 3 m long flight tube, two sets of detector assemblies, and data acquisition and processing, vacuum, power supply, and control sub-systems. The neutral outflux is gated in bunches of 1 μs time scale by a slotted rotating disc which is driven by a vacuum compatible motor modified from a turbomolecular pump. A He-Ne laser beam is projected through the disc slit to record the instants of chopper slits opening with an avalanche photodiode module. An on-axis electron multiplier detects chopped neutrals, and a central perforated Cu-Be plate is employed to channel the emitted secondary electrons into an off-axis electron multiplier. The radiation peaks of on-axis electron multiplier caused by UV photons projected through the central hole of the Cu-Be plate provide an alternative way to record the chopper slits' opening time. With an additional 4 TB fast memory card, 1 GS/s sampling rate has been realized by using a GaGe acquisition card continuously. The LENPA data from the EAST together with neutral particle material erosion experiments will be used to benchmark the simulation results for better predictions on future fusion reactors, such as ITER and China Fusion Engineering Test Reactor (CFETR).

Abstract
Objectives To investigate the mortality and causes of death in Chinese patients with systemic lupus erythematosus. Methods We collected the clinical data of all consecutive adult systemic lupus erythematosus patients at the Rheumatology department of Peking University First Hospital between January 2007 and December 2015. The primary causes of death were identified, the standardized mortality ratio and years of life lost were calculated, and the survival and variables associated with mortality were determined by Kaplan–Meier and Cox regression analysis respectively. Results The mean age of all 911 patients (814 females and 97 males) was 37.8 ± 14.7 years, the median disease duration at recruitment was 2.6 (0.5–7.0) years, and the median follow-up duration was 3.0 (1.4–5.1) years. Among the 911 patients who were successfully followed up, 45 patients died. Infection (31.1%) was the leading cause of death followed by renal failure, pulmonary arterial hypertension and cerebrovascular diseases. The overall age and sex-adjusted standardized mortality ratio was 3.2 (95% confidence interval 2.4–4.0), and the years of life lost for women and men were 29.8 and 9.4 respectively. Overall survival at 1, 5 and 10 years was 98.2%, 95.3% and 93.7% respectively. Older age at disease onset, infection, autoimmune hemolytic anemia, thrombocytopenia and pulmonary arterial hypertension were independent risk factors for the mortality of systemic lupus erythematosus patients, and longer disease duration at recruitment was an independent protective factor. Conclusions Mortality of systemic lupus erythematosus patients in China was substantial, especially in females, with infection the leading cause of death. Older age at disease onset, infection, autoimmune hemolytic anemia, thrombocytopenia and pulmonary arterial hypertension were associated with poor outcomes.

Abstract
Objective: To analyze the relationship between the breast cancer molecular classification and the prognosis of patients underwent breast-conserving therapy and to discuss the safety of the breast conserving surgery from the choice of operation in terms of breast cancer molecular classification. Methods: Clinical data of 618 patients with breast-conserving therapy in Tianjin Medical University Cancer Institute and Hospital from August 2005 to August 2010 were analyzed retrospectively. According to the molecular classification when breast cancer was diagnosed, patients were subdivided into five groups, including Luminal A, Luminal B1, Luminal B2, HER-2-positive and Triple-negative. Clinicopathological characteristics and prognosis were compared among five groups and the influencing factors of local recurrence, distant metastasis and overall survival were analyzed. Results: Among 618 patients, there were 148 cases Luminal A, 231 cases Luminal B1, 63 cases Luminal B2, 40 cases HER-2-positive and 136 cases Triple-negative. The age, family history, TNM stage, calcification, histological grade, pathological type and response to endocrine therapy of these 5 molecular types of breast cancer patients were significantly different (all P<0.05). The 5-year local regional recurrence-free survival rates of Luminal A, Luminal B1, Luminal B2, HER-2-positive and Triple-negative were 99.3%, 98.7%, 98.4%, 94.9% and 95.9%, respectively, without significant differences (P=0.104). The 5-year distant metastasis-free survival rates of these 5 types were 97.3%, 95.7%, 93.7%, 87.5% and 91.4%, respectively, with significant differences (P=0.013). Moreover, the 5-year overall survival rates of these 5 types were 98.6%, 97.8%, 98.4%, 92.5% and 95.6%, respectively, without significant differences (P=0.153). Multifactor analysis showed that radiotherapy (HR=0.036, P=0.049) and the number of lymph node metastases (HR=10.72, P=0.004) were independent factors of local recurrence of breast cancer patients underwent breast-conserving therapy. The age (HR=0.369, P=0.046), status of surgical margin (HR=5.486, P=0.007), number of lymph node metastases (HR=2.882, P=0.023) and molecular typing (HR=5.191, P=0.008) were independent factors of distant metastasis of above breast cancer patients. None of the factors were found to be independent factors of the overall survival of these breast cancer patients. Conclusions: Breast conserving therapy does not increase the risks of local recurrence and death of HER-2-positive and Triple-negative breast cancer patients. Therefore, breast conserving therapy can be accepted by patients with HER-2-positive and Triple-negative breast cancer.

Abstract
Sex hormone receptors play critical roles in development and reproduction. However, it is not known whether they exist in Raillietina tapeworms, and if they do, whether they have a similar function to that in vertebrates. We examined the immunohistochemical distributions of androgen receptors (ARs), estrogen receptors (ERs), and progesterone receptors (PRs) in the tissues of two tapeworm species: Raillietina echinobothrida and Raillietina tetragona. Immunopositive ARs were found in the entire reproductive system of R. echinobothrida, including the testes, ovaries, and oocysts, and weakly immunopositive ERs and PRs were found in the testes, ovaries, and oocysts. Immunopositive ARs were also found throughout the entire reproductive system of R. tetragona, including the testes, ovaries, and oocysts, and weakly immunopositive ERs were in the testes and oocysts; the PRs were distributed in an immunonegative manner. The results show that androgens and their receptors play critical roles in reproductive system development in the two tapeworms. The immunoreactivity and tissue localizations of the sex hormone receptors suggest that, in both species, they have similar functions as in vertebrates, and modulate reproduction.

Abstract
Objective: To explore the impact of immediate breast reconstruction on the onset of adjuvant chemotherapy and on the postoperative complications. Methods: We retrospectively analyzed the clinical data from female breast cancer patients treated by either modified radical mastectomy with immediate breast reconstruction(IBR) ( n=108) or modified radical mastectomy alone(n=115), followed by adjuvant chemotherapy at our department between January 2011 and December 2012. Results: There was no significant difference in the overall complication rates between the IBR group and modified radical mastectomy group (49.1% vs. 52.2%, P=0.87). However, more secondary surgery was applied in the IBR group than the modified radical mastectomy group (13.0% vs. 1.7%, P=0.001). However, the incidence of hematoma in the modified radical mastectomy group was significantly higher than the IBR group (17.4% vs. 4.6%, P=0.003). There was a significant difference in the onset of adjuvant chemotherapy between the IBR group and modified radical mastectomy group (21 days vs. 11days, P<0.001). Conclusions: Immediate breast reconstruction has no significant impact on the overall complication rate, but increases the incidence of secondary surgery, especially after the initiation of chemotherapy. In addition, it slightly delays adjuvant chemotherapy in the patients.

Abstract
The search for novel image contrasts has been a major driving force in the magnetic resonance (MR) research community, in order to gain further information on the body’s physiological and pathological conditions. Chemical exchange saturation transfer (CEST) is a novel MR technique that enables imaging certain compounds at concentrations that are too low to impact the contrast of standard MR imaging and too low to directly be detected in MRS at typical water imaging resolution. For this to be possible, the target compound must be capable of exchanging protons with the surrounding water molecules. This property can be exploited to cause a continuous buildup of magnetic saturation of water, leading to greatly enhanced sensitivity. The goal of the present review is to introduce the basic principles of CEST imaging to the general molecular imaging community. Special focus has been given to the comparison of state-of-the-art CEST methods reported in the literature with their positron emission tomography (PET) counterparts.
