Abstract
This paper aims to evaluate residential air conditioning systems' performance enhancement and optimization by adopting a novel functionalized Al2O3 (FAl2O3)-Polyolester (POE) nanolubricant. Comprehensive discussions were conducted on key performance parameters, including heat absorption, compressor work, cooling capacity, coefficient of performance (COP), and power consumption. Novel FAl2O3 nanoparticles were dispersed into the POE lubricant using a two-step method. The findings reveal that FAl2O3-POE nanolubricant exhibits superior heat absorption compared to pure POE. Heat absorption decreases with an increased initial refrigerant charge, while cooling capacity performance improves with an increased initial refrigerant charge. The COP shows an increasing trend at all concentrations of FAl2O3-POE nanolubricant when operating with R32. FAl2O3-POE/R32 demonstrates an enhanced range of 3.12%-32.26% for COP. The results suggest that applying novel FAl2O3-POE nanolubricant with R32 can reduce electrical power consumption by 13.79%-19.35%. The central composite design (CCD) offers an optimal condition for FAl2O3-POE nanolubricant with a concentration of 0.11 vol%, an initial refrigerant charge of 0.442 kg, resulting in a COP of 3.982, a standard error of 0.019, and a desirability of 1.0.

Abstract
Abstract
Background
There is increasing evidence that inflammatory biomarkers growth differentiation factor 15 (GDF-15) and neutrophil-lymphocyte ratio (NLR) appear to be associated with stroke and adverse cardiovascular events in patients with atrial fibrillation (AF). However, long-term impact of catheter ablation (CA) on GDF-15 and NLR is still unknown.
Objective
To evaluate the long-term change in GDF-15 and NLR after CA in paroxysmal AF patients.
Methods
A total of 58 paroxysmal AF patients were consecutively enrolled to perform CA. The inflammatory biomarkers GDF-15 and NLR were measured at baseline and 6-months postablation.
Results
All patients except one could complete 6-Months follow up. Fifty (87.7%) patients maintained sinus rhythm (SR group) and seven (12.3%) patients sustained AF recurrence (AFR group). No significant difference was noted in clinical and procedural characteristics between two groups (p>0.05), except mean fluoroscopy time (minutes 22±11.7 vs. 13±5.3, p=0.001) significantly longer in AFR than SR group. The GDF-15 (pg/ml 195±57 vs. 216±88, p=0.398), and NLR (% 1.8 (1.3–3) vs. 2.6 (1.4–3.4), p=0.395) were comparable at baseline in both SR and AFR groups respectively. At 6-months postablation, GDF-15 (pg/ml 133±41 vs. 195±57, p<0.001), and NLR (% 1.6 (1.1–2) vs. 1.8 (1.3–3), p=0.004) were significant deceased compared to baseline levels in SR group. However, GDF-15 (pg/ml 139±86 vs. 216±88, p=0.064), and NLR (% 1.6 (1.2–3) vs. 2.6 (1.4–3.4), p=0.398) biomarkers remained comparable to baseline level in AFR group (p>0.05)
Conclusion
Inflammatory biomarkers; GDF-15 and NLR significantly decreased at long-term on successful maintenance of sinus rhythm by CA in paroxysmal AF patients.

Abstract
Previous research has showed that miR-99a-5p was a tumor suppressor. The aim of our study was to explore the effect of miR-99a-5p on the vitality and proliferation, migration together with the invasion of oral tumor cells via inhibiting the expression of NOX4. QRT-PCR and Western blot were applied to examine the expression level of miR-99a-5p and NOX4 in human oral tumorous and adjacent tissues. Dual luciferase reporter gene assay was applied to confirm that miR-99a-5p negatively regulated directly on NOX4 in TSCC1 cells. Cell transfection and lentiviral vectors were used to up-regulate expression of miR-99a-5p and NOX4, respectively. Cell proliferation, cell cycle, apoptosis and invasion along with the migration in different groups were assessed using MTT assay, colony formation assay, the flow cytometry, transwell assay and the wound healing assay, respectively. MiR-99a-5p was under-expressed in human oral tumor, while NOX4 was over-expressed. There was a negative relationship between miR-99a-5p and NOX4. Up-regulating miR-99a-5p or down-regulating NOX4 suppressed the vitality, proliferation, migration together with invasion of TSCC1 cells. MiR-99a-5p affected the vitality and proliferation, migration together with the invasion of oral tumor cells through targeting NOX4.

Abstract
DNA replication machinery is responsible for accurate and efficient duplication of the chromosome. Since inhibition of DNA replication can lead to replication fork stalling, resulting in DNA damage and apoptotic death, inhibitors of DNA replication are commonly used in cancer chemotherapy. Ribonucleotide reductase (RNR) is the rate-limiting enzyme in the biosynthesis of deoxyribonucleoside triphosphates (dNTPs) that are essential for DNA replication and DNA damage repair. Gemcitabine, a nucleotide analog that inhibits RNR, has been used to treat various cancers. However, patients often develop resistance to this drug during treatment. Thus, new drugs that inhibit RNR are needed to be developed. In this study, we identified a synthetic analog of resveratrol (3,5,4’-trihydroxy-trans-stilbene), termed DHS (trans-4,4’-dihydroxystilbene), that acts as a potent inhibitor of DNA replication. Molecular docking analysis identified the RRM2 (ribonucleotide reductase regulatory subunit M2) of RNR as a direct target of DHS. At the molecular level, DHS induced cyclin F-mediated down-regulation of RRM2 by the proteasome. Thus, treatment of cells with DHS reduced RNR activity and consequently decreased synthesis of dNTPs with concomitant inhibition of DNA replication, arrest of cells at S-phase, DNA damage, and finally apoptosis. In mouse models of tumor xenografts, DHS was efficacious against pancreatic, ovarian, and colorectal cancer cells. Moreover, DHS overcame both gemcitabine resistance in pancreatic cancer and cisplatin resistance in ovarian cancer. Thus, DHS is a novel anti-cancer agent that targets RRM2 with therapeutic potential either alone or in combination with other agents to arrest cancer development.

Abstract
The aim of this study was to compare the morbidity, mortality, oncological results and quality of life between laparoscopic radical cystectomy (LRC) and open radical cystectomy (ORC) in the elderly patients over 75 years old. Between January 2012 and January 2015, 60 patients were recruited into this study, who were randomly assigned in a 1:1 ratio to either LRC or ORC group. Baseline patient characteristics, pathological factors, operative and postoperative characteristics, postoperative complications and survival data were retrospectively collected, analyzed and compared between the two groups. Patients in LRC group and ORC group had comparable baseline characteristics and pathological factors (all P > 0.05). LRC group required longer operative time (408.2 ± 76.9 vs. 311.7 ± 65.3 min, P = 0.000) and had less EBL (621.6 ± 100.7 vs. 1088.5 ± 109.4 ml, P = 0.000) compared with ORC group. The incidence of infection and ileus within 90 days after surgery in ORC group was significantly higher than LRC group(6.9% vs. 28.6%, P = 0.041; 3.4% vs. 25%, P = 0.025). At a median follow-up of 28 months (range 12–48 months), the survival analysis showed that there were no significant differences between the LRC and ORC groups in overall survival (log-rank χ2 = 0.122; P = 0.726), or progress-free survival (log-rank χ2 = 0.153; P = 0.696). In conclusion, this study confirmed that LRC could achieve similar tumor treatment efficacy compared to ORC, with fewer perioperative complications and less blood loss. We suggest that LRC should be considered as the primary intervention for patients aged over 75 years old with muscle invasive bladder cancer or non-muscle invasive bladder cancer with high risk factors.

Abstract
China's prevention and control of parasitic diseases has made remarkable achievements. However, the prevalence and transmission of parasitic diseases is impacted by the complicated natural and social factors of environment, natural disasters, population movements, and so on. Therefore, there are still the risks of the outbreak of emergency parasitic diseases affairs, which may affect the control effectiveness of parasitic diseases and endanger the social stability seriously. In this article, we aim at the analysis of typical cases of emergency parasitic disease affairs and their impacts on public health security in China in recently years, and we also elaborate the disposal characteristics of emergency parasitic disease affairs, and propose the establishment of response system to emergency parasitic disease affairs in China, including the organizational structure and response flow path, and in addition, point out that, in the future, we should strengthen the system construction and measures of the response system to emergency parasitic disease affairs, so as to control the risk and harm of parasitic disease spread as much as possible and to realize the early intervention and proper disposal of emergency parasitic disease affairs.

Abstract
Objective To study the effect of schistosomiasis transmission interruption model based on intensive agriculture in hilly endemic areas, so as to provide the reference for the similar endemic areas. Methods Based on the development of intensive agriculture in Guanghan City, a comprehensive demonstration area of schistosomiasis control with measures such as new rural construction, hardening ditches, the adjustment of industrial structure and water remediation measures was constructed. Jinhua, Shiguan and Hongyan villages were chosen as the evaluation sites to comparatively analyze the indexes of intensive agriculture and schistosomiasis control effects. Results Compared with the demonstration area before construction, in 2014, the harden rates of ditches and village roads were increased by 49.57% and 39.33% respectively; and the proportion of agricultural machinery increased by 25%. The positive rate of serological tests of schistosomiasis was decreased by 81.74%. The Oncomelania hupensis snail area was decreased from 2.44 hm2 (2007) to 0 (2014). The awareness rate of schistosomiasis control knowledge and correct behavior rate of the residents were increased from 51.28% and 90.85% to 91.29% and 97.69% respectively. The experience of the demonstration area ensured the entire Guanghan District achieved the schistosomiasis transmission interruption criterion at the end of 2014. Conclusions The schistosomiasis control model of intensive agriculture combined with other comprehensive measures has a good effect on interrupting the endemic of schistosomiasis, and it can realize the sustainable development of the agricultural economy and schistosomiasis control.

Abstract
Zinc is an essential trace element in the human body and it participates in various pathways of metabolism. Cordyceps sinensis is a wellknown traditional Chinese medicine that contains cordycepin, cordycepic polysaccharides, proteins, vitamins, trace elements, and many other biological active materials. In this study, we cultured C. sinensis in liquid medium containing Zn ions and then analyzed the biomass, the ratios of total Zn accumulation, and the organic Zn content in the mycelia. The results showed that when the media contain 150 mg/L Zn, the biomass of mycelia of C. sinensis reached 10.7 g/L and the Zn content present in the mycelia reached 4875.1 microg/g. The percentage of Zn accumulated in the mycelia was 34.05% of the total Zn in the media, of which the organic Zn accounted for 76.33%. The results also revealed that the content of total amino acid (TAA) and essential amino acid (EAA) in the mycelia were increased substantially TAA and EAA in the Zn-treated mycelia were 11.1% and 15.2% higher, respectively, than that in the mycelia without Zn treatment. These results will be useful for elucidation of the physiological mechanism of Zn effects on the biological metabolism in the mycelia of C. sinensis.

Abstract
Three different synthetic routes to the fourth-generation (G4) macromonomers 4, 6, and 9 for Suzuki polycondensation (SPC) are described and compared in their efficiency. Monomer 9 was selected the best as judged by the number and feasibility of synthetic steps and purification behavior and could be prepared in a 15 g scale. SPC of the monomers 4, 6, and 9 gave the novel poly(para-phenylene)s 17, 18, and 19 with pendant G4 dendrons at every other repeat unit. SPC was optimized for 9 and the diboronic acid ester counterpart 16 which led to polymer 19 with a molecular weight of up to Mn=76,000, Mw=63,9000 (GPC versus polystyrene). High molecular weight is most likely to be obtained for the attempted stoichiometry 9:16 = 1.000:(0.995-1.005).

Abstract
Coronary heart disease mortality is four times higher in Lithuanian compared to Swedish middle-aged men. Using the same equipment (Acuson XP10 with 5 MHz linear transducer) and staff, we compared the amount of atherosclerosis in carotid and femoral arteries in 100 randomly sampled 50-year-old men in each of the cities Vilnius, Lithuania and Linköping, Sweden. Atherosclerotic plaques were more abundant in Vilnius men compared to Linköping men (53 versus 28% in the common carotid artery, 73 versus 37% in the common femoral artery, P < 0.001 for both). Plaques were thicker and more extended in arteries of Vilnius men, and an ultrasound atherosclerosis score was higher in both carotid and femoral arteries (P < 0.001 for all). More Vilnius men had a maximal intima-media thickness of the common femoral artery above 1 mm (P<0.005). Stiffness in the common carotid artery was higher in Vilnius men (P<0.001). In a linear regression model of the pooled material, after adjustment for city was made, smoking, systolic blood pressure, low density lipoprotein cholesterol and beta-carotene (inversely) significantly contributed to a high total ultrasound score (r2 = 0.32). These findings show that the higher coronary mortality noted in Lithuanian men goes together with a higher prevalence of early peripheral atherosclerosis.

Abstract
In order to assess the effectiveness of Vaxigrip in 1996-1997, we chose 1356 people in the Chinese Army, who had not recently had influenza and who were divided into an injection group and a control group. The injection group consisted of 80 children aged 3-6 years, 363 adults aged 18-59 years and 235 people over 60 years of age. The control group consisted of 88 children aged 3-6, 372 adults aged 18-59 and 218 people over 60. They were observed from the 21st day to the 6th month after Vaxigrip administration. Each person was requested to report having a body temperature over 38.5 degrees C, headache, myalgia or arthalgia, cough, pharyngodynia or nasal obstruction. Fever due to other causes was not included in the influenza symptoms. We counted the symptoms of influenza and common cold only once during the observation period. Our final finding was that the incidence rates of the influenza and common cold symptoms were reduced by 84.8% in children, 74.0% in adults and 68.6% in elderly people. In comparison with the control group, the incidence rate of influenza-like symptoms was reduced by 71.1% in the injection group, and the incidence rate of common cold symptoms in the injection group was lower than that in the control group. There was no large difference by age. The incidence rate of symptoms of upper respiratory tract infection in the injection group was 47.5% lower than that in the control group. Our findings are basically the same as those in other countries.

Abstract
Endonuclease III (endoIII; nth gene product) of Escherichia coli is known to be a DNA repair enzyme having a relatively broad specificity for damaged pyrimidine bases of DNA. Here, we describe the cloning and characterization of the cDNA and the gene for a mouse homologue (mNthl1/mNth1) of endoIII. The cDNA was cloned from a mouse T-cell cDNA library with a probe prepared by PCR using the library and specific PCR primers synthesized based on the reported information of partial amino acid sequences of bovine NTHL1/NTH1 and of EST Data Bases. The cDNA is 1025 nucleotides long and encodes a protein consisting of 300 amino acids with a predicted molecular mass of 33.6 kDa. The amino acid sequence exhibits significant homologies to those of endoIII and its prokaryotic and eukaryotic homologues. The recombinant mNthl1 with a hexahistidine tag was overexpressed in a nth::cmr nei::Kmr double mutant of E. coli, and purified to apparent homogeneity. The enzyme showed thymine glycol DNA glycosylase, urea DNA glycosylase and AP lyase activities. Northern blot analysis indicated that mNthl1 mRNA is about 1 kb and is expressed ubiquitously. A 15 kb DNA fragment containing the mNthl1 gene was cloned from a mouse genomic library and sequenced. The gene consists of six exons and five introns spanning 6.09 kb. The sequenced 5' flanking region lacks a typical TATA box, but contains a CAAT box and putative binding sites for several transcription factors such as Ets, Sp1, AP-1 and AP-2. The mNthl1 gene was shown to lie immediately adjacent to the tuberous sclerosis 2 (Tsc2) gene in a 5'-to-5' orientation by sequence analysis and was assigned to chromosome 17A3 by in situ hybridization.
