Abstract
Objective: To investigate the impact of different levels of systolic blood pressure on all-cause, cardiovascular and cerebrovascular mortality in patients with nonvalvular atrial fibrillation (AF). Methods: This is a prospective cohort study. Patients with AF or atrial flutter diagnosed by 12 lead electrocardiogram during physical examination of Kailuan Group employees from July 2006 to December 2017 or previously diagnosed with AF in an inpatient setting at a level 2A hospital or above were eligible for the study. Baseline clinical characteristics including age, gender, systolic blood pressure were collected. According to the level of systolic blood pressure, patients were divided into systolic blood pressure<120 mmHg (1 mmHg=0.133 kPa)group, 120 mmHg ≤ systolic blood pressure<140 mmHg group, and systolic blood pressure ≥140 mmHg group. The time of first diagnosis with AF was defined as the start of follow-up and the final follow-up ended at December 2018. Primary endpoint was all-cause death. Related information was obtained through the social security system or inpatient medical records. The cause of death was defined according to the International Classification of Diseases disease (ICD-10) codes by professional medical stuffs. Multifactorial Cox proportional risk model was used to analyze the relative risk ratios for the occurrence of death in different systolic blood pressure level groups. The relationship between systolic blood pressure levels and mortality in the patients with AF was analyzed by using natural spline function curves. Results: A total of 1 721 patients with AF were enrolled (average age=(67.0±9.0) years), patients were followed up for (6.3±3.8) years. 544 out of 1 721 patients with AF died during the follow-up period (31.61%). The cumulative incidence rate of all-cause mortality, cardiovascular and cerebrovascular death was 26.13%, 25.59%, 36.96% and 14.86%, 11.87%, 19.76% respectively in the systolic blood pressure<120 mmHg, 120 mmHg ≤ systolic blood pressure<140 mmHg and systolic blood pressure ≥140 mmHg groups. The cumulative incidence rate of all-cause, cardiovascular and cerebrovascular death was significantly higher in the group with systolic blood pressure ≥140 mmHg than in 120 mmHg ≤ systolic blood pressure<140 mmHg group (P<0.05). Compared with 120 mmHg ≤ systolic blood pressure<140 mmHg group, multivariable Cox proportional hazards regression models showed that the HRs (95%CI) for all-cause, cardiovascular and cerebrovascular death were 1.47 (1.20 to 1.79) and 1.69 (1.27 to 2.26) for the group with systolic blood pressure ≥ 140 mmHg (P<0.05). In contrast, the HRs (95%CI) for all-cause, cardiovascular and cerebrovascular death in the systolic blood pressure<120 mmHg group were 0.99 (0.73-1.35) and 1.24 (0.82-1.89), respectively, with no statistically significant differences between the two groups (P>0.05). The natural spline curve showed that there was a "U" relationship between systolic blood pressure levels and all cause death and cardiovascular and cerebrovascular death in this patient cohort. Systolic blood pressure greater than or less than 123 mmHg was associated with increased risk of death of AF patients in this cohort. Conclusion: Compared with systolic blood pressure<120 mmHg and systolic blood pressure≥140 mmHg group, the risk of all-cause and cardiovascular and cerebrovascular death is the lowest in AF patients with 120 mmHg ≤ systolic blood pressure<140 mmHg in this cohort.

Abstract
The trichilemmal carcinoma is a rare tumor that usually occurs on sun-exposed skin, especially on the face, scalp, neck and back of hands, mainly in elderly subjects but commonly between the 4th and 9th decades of life. We report a case of giant trichilemmal carcinoma. A 65-year-old man presented with a 5-year history of a slowly developing mass arising from his right retroauricular region, with local destruction of the auricle. The lesion appeared as a 8.0 cm×6.5 cm×2.0 cm sized, with surface ulceration and erosion, subcutaneous nodule, and mild tenderness. Preoperative pathological biopsy showed: "retroauricular" trichilemmal carcinoma. The patient underwent right retroauricular tumor resection, partial auriculectomy, neck adjacent skin flap repair and auricle reconstruction. Postoperative pathological report: "retroauricular" trichilemmal carcinoma. The margin of incision was negative, and the lymph nodes in zone II were negative. Immunohistochemistry: Tumor cells were CK5/6(++), p63(++), p40(++), CD10(-), EMA(-), Ki-67(+, about 60%).

Abstract
Objective: To study the effect and its mechanism of recombinant human bone morphogenetic protein 7 (rhBMP-7) on urethral keloid fibroblast. Methods: Urethral fibroblasts were extracted and cultured, and the fourth-generation fibroblasts were used for experiment. Urethral fibroblasts were treated with rhBMP-7. Proliferation rate was detected by CCK-8 method. RT-PCR was applied to test changes of mRNA in α smooth muscle actin (α-SMA) and type Ⅰ collagen protein (COL-1) of each group. Western blot was used to measure α-SMA protein expression and the effect of rhBMP-7 on signaling pathway of urethral keloid fibroblasts. Results: With the increase of rhBMP-7 concentrations, the proliferation rate of urethral keloid fibroblast was generally decreased. Cells kept proliferating with time at the same concentration of rhBMP-7. mRNA level of COL-1 and α-SMA in rhBMP-7-treated (>20 ng/ml) urethral keloid fibroblasts was greatly reduced with statistical significance (P<0.05) and dose dependency. It was found rhBMP-7 inhibited the overexpression of p-smad2/3 and α-SMA mediated by transforming growth factor beta 1 (TGF-β(1)) signaling pathway. Conclusion: rhBMP-7 could adjust TGF-β(1) signaling pathway to inhibit gene expression of COL-1 and a-SMA in urethral keloid fibroblast, which provided evidences for further animal experiments or clinical trials.

Abstract
Using a Fe/Cu bimetallic system (Fe/Cu system), the discoloration of both methylene blue in aqueous solution and the colored wastewater from a plant was investigated under the anaerobic condition in batch or continuous reactors. Results show that the Fe/Cu system effectively removed the color with over 88% of color removal efficiency for both methylene blue solution and the wastewater from the plant in batch test. Color removal efficiencies increased rapidly with Fe/Cu dosage and reaction time, respectively, at initial time and slowly to stable values. Optimum pH was neutral range. In addition, in continuous test it also removed the color of the wastewater from the plant with 63% of discoloring efficiency under the condition of 2 h of hydraulic retention time and neutral range of pH (7.0-8.3). High discoloring efficiencies with low chemical oxygen demand removal efficiencies were found in all experiments. The reduction of chromophores in pollutants was the main mechanism of the discoloration in the Fe/Cu system.

Abstract
The periodic variation of operation states in triple ditch (BIO-DENITRO process) was investigated in a pilot-scale and a full-scale triple ditch treating raw wastewater containing 70% petrochemical wastewater and 30% domestic wastewater. Mathematical models describing the periodic variation of activated sludge concentrations in each ditch were proposed based on theoretical analysis and were verified in the pilot-scale and full-scale triple ditches respectively. The existence of optimal cycle time and time arrangement of periodic operation programs were demonstrated and discussed according to the mathematical models and the experimental results of the pilot-scale triple ditch operated in four different stages. Four rulers determining the duration and operation programs are suggested.

Abstract
AIM To investigate the possibility of using poly (epsilon-caprolactone-block-D, L-lactide) (PLCA) as a kind of materials to prepare the microparticles drug carrier. METHODS PCLA-MP (microparticle, MP) was prepared by double-emulsification solvent evaporation method. Its morphology was examined by scanning electron microscope. Its size diameter was examined by particle analyser. Insulin (INS), as a model drug, was then encapsulated into PCLA-MP (INS-PCLA-MP). HPLC method was established for determining INS in INS-PCLA-MP. An "antibody-capture" procedure was devised for investigating encapsulation mechanism. The in vitro release behaviour of INS-PCLA-MP was determined in phosphatic buffer solution (pH 7.4). The diabetic rat model was established and blood glucose levels were measured using glucose oxidase (GOD-PAP) method to evaluate the hypoglycaemic effects after subcutaneous administration of INS-PCLA-MP. The pharmacological bioavailability (PBA) of INS-PCLA-MP was calculated from the area above the curve (AAC) in contrast with INS-solution. RESULTS The mean diameter of INS-PCLA-MP was 1.9 microns, while the encapsulation ratio of INS reached to 76.46%. Only 18.25% encapsulated INS was on the surface of the microparticles, it could be measured by "antibody-capture" experiment. The in vitro release curve of INS-PCLA-MP consists of initial rapid release stage followed by slower exponential stage. In pharmacodynamic studies, after subcutaneous administration of INS-PCLA-MP 12 u.kg-1, the hypoglycaemic effect was significant. The PBA of INS-PCLA-MP was 123.08%. CONCLUSION PCLA might become a new drug carrier material in the future.
