Abstract
Prostate cancer (PC) is the most common carcinoma among men worldwide which results in 26% of leading causes of cancer-related death. However, the ideal and effective molecular marker remains elusive. CircRNA, initially observed in plant-infected viruses and Sendai virus in 1979, is generated from pre-mRNA back-splicing and comes in to play by adequate expression. The differential expression in prostate tissues compared with the control reveals the promising capacity in modulating processes including carcinogenesis and metastasis. However, the biological mechanisms of regulatory network in PC needs to systemically concluded. In this review, we enlightened the comprehensive studies on the definite mechanisms of circRNAs affecting tumor progression and metastasis. What's more, we validated the potential clinical application of circRNAs serving as diagnostic and prognostic biomarker. The discussion and analysis in circRNAs will broaden our knowledge of the pathogenesis of PC and further optimize the current therapies against different condition.

Abstract
Background Scrub typhus is an acute febrile illness, which was caused by Orientia tsutsugamushi and transmitted through the bite of chiggers. The diagnosis of scrub typhus could be missed diagnosis due to the absence of the pathognomonic eschar. Case presentation A 76-year-old man was hospitalized with fever and kidney injury and was diagnosed of hemorrhagic fever with renal syndrome first. However, the situation of the illness deteriorated into refractory septic shock and multiple organ dysfunction rapidly,although the treatment of anti-sepsis was used in 3rd-5th day. Orientia tsutsugamushi was determined to be the causative pathogen by Next-generation sequencing of his plasma sample in 6th day. Then, the patient was treated with doxycycline and azithromycin and recovered quickly. Conclusions Next-generation sequencing was a new diagnostic technology and could identify scrub typhus in accurately and fast without the pathognomonic eschar.

Abstract
Dichromate is a widespread contaminant in wastewater, threatening the health of humans and other organisms. Therefore, effective detection and removal of dichromate from water is of great significance. Herein, a tetraphenylethylene functionalized cationic organic network (CON-LDU2) was constructed via a facile quaternization reaction. CON-LDU2 was successfully integrated with both detection and removal functionalities toward dichromate. On the one hand, benefiting from the strong fluorescence, CON-LDU2 was employed as a chemosensor, it could efficiently and selectively probe Cr2O72- in water with "turn-off" fluorescent response. On the other hand, the cationic skeleton and free anions inside framework make CON-LDU2 an excellent adsorbent for Cr2O72-, it could capture Cr2O72- from water with rapid kinetics and high capacity. The kinetic constant for adsorption of Cr2O72- can reach up to 1.784 g mg-1 min-1, while the capacity is determined as 325 mg g-1. Furthermore, CON-LDU2 displayed good recyclability and can be reused for at least 5 cycles. Therefore, CON-LDU2 can serve as an ideal candidate not only in detection but also in removal of Cr2O72- in water medium.

Nitrogen isotope variations of ammonium across rain events: Implications for different scavenging between ammonia and particulate ammonium. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2018; 239:392-398.

Abstract
Enhanced ammonia (NH3) emissions and deposition caused negative effects on air quality and ecosystems. Precipitation is an efficient pathway to remove NH3 and particulate ammonium (p-NH4+) from the atmosphere into ecosystems. However, precipitation scavenging of p-NH4+ in chemical transport models has often considered fine p-NH4+, with inadequate constraints on NH3 and coarse p-NH4+. Based on distinct δ15N values between NH3 and NH4+ in PM2.5 (particulate matters with aerodynamic diameters ≤ 2.5 μm) or TSP (total suspended particulates), this paper interpreted intra-event variations of precipitation NH4+ concentrations and δ15N values (δ15N-NH4+ values) at Guiyang (Xiao et al., 2015). Generally decreased NH4+ concentrations across rain events reflected decreasing scavenging of NH3 and p-NH4+. Using a Bayesian isotope mixing model, we found that differing contributions between 15N-depleted NH3 and 15N-enriched p-NH4+ were responsible for the three-stage variations of intra-event δ15N-NH4+ values. The decreases of δ15N-NH4+ values across the first and third stages indicated more decreases in scavenging p-NH4+ than NH3, while the increases of δ15N-NH4+ values across the second stage were resulted primarily from more increases in scavenging p-NH4+ (particularly fine p-NH4+) than NH3. These results stressed influences of differing scavenging between NH3 and p-NH4+ on precipitation δ15N-NH4+ values, which should be considered in modeling precipitation scavenging of atmospheric p-NH4+.

Abstract
Objective: To investigate the clinicopathological features of EBV-positive T/NK cell lymphoproliferative diseases (EBV(+) T/NK-LPD). Methods: The clinical characteristics of 156 cases of EBV(+) T/NK-LPD were collected from August 2002 to March 2015 at Beijing Friendship Hospital, Capital Medical University. Immunohistochemical staining, EBER in situ hybridization and clonal analysis of TCR gene were performed. All patients were followed up. Results: There were 106 male and 50 female patients; patients' age ranged from 1 to 75 years (median 20 years). The course of the diseases before diagnosis ranged from 2 to 540 months (median 20 months). Fever was noted in 122 patients (78.2%), 108 patients had lymphadenopathy (69.2%), and 75 patients had hepatosplenomegaly (48.1%). Thirty-three cases were grade 1, 68 cases were grade 2, and 55 cases were grade 3. TCR gene arrangement analysis was performed in 45 cases, and 33 cases (73.3%) showed clonal rearrangement. The follow-up period ranged from 1-134 months, and 44 patients (28.2%) died. There was a trend of increased death rate associated with increasing grade (P>0.05). Conclusions: There are many types of EBV(+) T/NK-LPD, and they can be classified as systemic, relatively localized and localized. The prognosis should be based on a comprehensive analysis of pathology and clinical data. There is no significant correlation between morphological grade and mortality. An important goal of therapy is to prevent serious complications.

Abstract
Here we reported the fabrication of tungsten oxide (WO3-x ) nanowires by Ar+ ion irradiation of WO3 thin films followed by annealing in vacuum. The nanowire length increases with increasing irradiation fluence and with decreasing ion energy. We propose that the stress-driven diffusion of the irradiation-induced W interstitial atoms is responsible for the formation of the nanowires. Comparing to the pristine film, the fabricated nanowire film shows a 106-fold enhancement in electrical conductivity, resulting from the high-density irradiation-induced vacancies on the oxygen sublattice. The nanostructure exhibits largely enhanced surface-enhanced Raman scattering effect due to the oxygen vacancy. Thus, ion irradiation provides a powerful approach for fabricating and tailoring the surface nanostructures of semiconductors.

Abstract
To constrain sources of anthropogenic nitrogen (N) deposition is critical for effective reduction of reactive N emissions and better evaluation of N deposition effects. This study measured δ15N signatures of nitrate (NO3-), ammonium (NH4+) and total dissolved N (TDN) in precipitation at Guiyang, southwestern China and estimated contributions of dominant N sources using a Bayesian isotope mixing model. For NO3-, the contribution of non-fossil N oxides (NOx, mainly from biomass burning (24 ± 12%) and microbial N cycle (26 ± 5%)) equals that of fossil NOx, to which vehicle exhausts (31 ± 19%) contributed more than coal combustion (19 ± 9%). For NH4+, ammonia (NH3) from volatilization sources (mainly animal wastes (22 ± 12%) and fertilizers (22 ± 10%)) contributed less than NH3 from combustion sources (mainly biomass burning (17 ± 8%), vehicle exhausts (19 ± 11%) and coal combustions (19 ± 12%)). Dissolved organic N (DON) accounted for 41% in precipitation TDN deposition during the study period. Precipitation DON had higher δ15N values in cooler months (13.1‰) than in warmer months (-7.0‰), indicating the dominance of primary and secondary ON sources, respectively. These results newly underscored the importance of non-fossil NOx, fossil NH3 and organic N in precipitation N inputs of urban environments.

Inter-species and intra-annual variations of moss nitrogen utilization: Implications for nitrogen deposition assessment. ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2017; 230:506-515.

Abstract
Moss nitrogen (N) concentrations and natural 15N abundance (δ15N values) have been widely employed to evaluate annual levels and major sources of atmospheric N deposition. However, different moss species and one-off sampling were often used among extant studies, it remains unclear whether moss N parameters differ with species and different samplings, which prevented more accurate assessment of N deposition via moss survey. Here concentrations, isotopic ratios of bulk carbon (C) and bulk N in natural epilithic mosses (Bryum argenteum, Eurohypnum leptothallum, Haplocladium microphyllum and Hypnum plumaeforme) were measured monthly from August 2006 to August 2007 at Guiyang, SW China. The H. plumaeforme had significantly (P < 0.05) lower bulk N concentrations and higher δ13C values than other species. Moss N concentrations were significantly (P < 0.05) lower in warmer months than in cooler months, while moss δ13C values exhibited an opposite pattern. The variance component analyses showed that different species contributed more variations of moss N concentrations and δ13C values than different samplings. Differently, δ15N values did not differ significantly between moss species, and its variance mainly reflected variations of assimilated N sources, with ammonium as the dominant contributor. These results unambiguously reveal the influence of inter-species and intra-annual variations of moss N utilization on N deposition assessment.

Abstract
BACKGROUND A previous study provided evidence for a genetic association between PPP2CA on 5q31.1 and systemic lupus erythematosus (SLE) across multi-ancestral cohorts, but failed to find significant evidence for an association in the Han Chinese population. OBJECTIVES To explore the association between this locus and SLE using data from our previously published genome-wide association study (GWAS). METHODS Single-nucleotide polymorphisms (SNPs) rs7726414 and rs244689 (near TCF7 and PPP2CA in 5q31.1) were selected as candidate independent associations from a large-scale study in a Han Chinese population consisting of 1047 cases and 1205 controls. Subsequently, 3509 cases and 8246 controls were genotyped in two further replication studies. We then investigated the SNPs' associations with SLE subphenotypes and gene expression in peripheral blood mononuclear cells. RESULTS Highly significant associations with SLE in the Han Chinese population were detected for SNPs rs7726414 and rs244689 by combining the genotype data from our previous GWAS and two independent replication cohorts. Further conditional analyses indicated that these two SNPs contribute to disease susceptibility independently. A significant association with SLE, age at diagnosis < 20 years, was found for rs7726414 (P = 0·001). The expression levels of TCF7 and PPP2CA messenger RNA in patients with SLE were significantly decreased compared with those in healthy controls. CONCLUSIONS This study found evidence for multiple associations with SLE in 5q31.1 at genome-wide levels of significance for the first time in a Han Chinese population, in a combined genotype dataset. These findings suggest that variants in the 5q31.1 locus not only provide novel insights into the genetic architecture of SLE, but also contribute to the complex subphenotypes of SLE.

Abstract
Octopus minor (Sasaki, 1920) is an economically important cephalopod that is found in the northern coastal waters of China. In this study, we investigated genetic differentiation in fishery populations using amplified fragment length polymorphisms (AFLPs). A total of 150 individuals were collected from five locations: Dalian (DL), Yan-tai (YT), Qingdao (QD), Lianyungang (LY), and Zhoushan (ZS), and 243 reproducible bands were amplified using five AFLP primer combinations. The percentage of polymorphic bands ranged from 53.33 to 76.08%. Nei's genetic identity ranged from 0.9139 to 0.9713, and the genetic distance ranged from 0.0291 to 0.0900. A phylogenetic tree was constructed using the unweighted pair group method with arithmetic mean, based on the genetic distance. The DL and YT populations originated from one clade, while the QD, LY, and ZS populations originated from another. The results indicate that the O. minor stock consisted of two genetic populations with an overall significantly analogous FST value (0.1088, P < 0.05). Most of the variance was within populations. These findings will be important for more sustainable octopus fisheries, so that this marine resource can be conserved for its long-term utilization.

Abstract
AIMS In this study, the potential of calcium chloride (CaCl(2)) application to improve the efficacy of the marine antagonist Rhodosporidium paludigenum in controlling postharvest diseases of cherry tomatoes was assessed. METHODS AND RESULTS CaCl(2) alone was found not to have any direct influence on the population growth of R. paludigenum in NYDB cultures or in cherry tomato wounds. However, the combined treatments with 1 x 10(8) cells ml(-1)R. paludigenum and CaCl(2) at the concentration from 0.5 to 2% showed high activities to reduce black rot caused by Alternaria alternata in cherry tomato wounds, significantly higher than those of R. paludigenum or CaCl(2) alone. Meanwhile, 0.5% CaCl(2) in combination with 1 x 10(8) cells ml(-1)R. paludigenum greatly inhibited the natural decay of cherry tomatoes in 21 days' storage at 25 degrees C. CONCLUSIONS The combination of R. paludigenum and CaCl(2) enhances the inhibition of black rot and natural decay of postharvest cherry tomatoes. The results from this study provide a new way to improve the efficiency of R. paludigenum in maintaining the quality of postharvest fruits and vegetables. SIGNIFICANCE AND IMPACT OF THE STUDY The marine yeast R. paludigenum combined with CaCl(2) has greatly potential use as an alternative to chemical fungicides in inhibiting postharvest decay on cherry tomatoes.

Abstract
OBJECTIVE To investigate the influence of polyester gauze on evaporation capacity and its clinical effect after escharectomy of deep burn wound and micro-skin grafting. METHODS Twenty patients with deep burn admitted within 24 hours after injury underwent escharectomy and Meek skin grafting. Two surfaces of wound with the area of about 1% as the whole wound surface were used, one covered by Meek skin graft and polyester gauze as inner dressing (polyester gauze group), and the other covered by split-thickness skin sheet 0.3 mm x 0.3 mm in size and vaseline oil gauze as inner dressing (vaseline oil gauze group). Five days after skin grafting, the evaporation capacities of the surface of inner dressing, wound surface without dressing (nude wound), and normal skin near the wound were tested by evaporation test equipment. The complete healing time and survival rate of skin sheet in both groups were observed. The degree of pain during dressing change was evaluated with visual analog scale. RESULTS The evaporation capacity of the inner dressing surface of polyester gauze group was (24.8 +/- 5.2) ml x h(-1) x m(-2), significantly lower than those of the vaseline oil gauze group [(35.4 +/- 5.0) ml x h(-1) x m(-2), P < 0.01] and nude wound [(41.3 +/- 4.5) ml x h(-1) x m(-2), P < 0.01], and similar to that of the normal skin near the wound [(21.1 +/- 5.1) ml x h(-1) x m(-2), P > 0.05]. The evaporation capacity of the inner dressing surface of vaseline oil gauze group was significantly lower than nude wound [(40.7 +/- 3.6) ml x h(-1) x m(-2), P < 0.01], but significantly higher than the normal skin near the wound [(21.2 +/- 3.8) ml x h(-1) x m(-2), P < 0.01]. The survival rate of skin sheets of the polyester gauze group was 98% +/- 3%, not significantly different from that of the vaseline oil gauze group (98% +/- 2% , P > 0.05). The wound healing rates on days 10, 15, and 20 of the polyester gauze group were 80% +/- 20%, 96% +/- 7%, and 100% respectively, all significantly higher than those of the vaseline oil gauze group (70% +/- 33%, 81% +/- 21%, and 97% +/- 11% respectively, all P < 0.01). The complete healing time of the polyester gauze group was (13.6 +/- 1.9) days, significantly shorter than that of the vaseline oil gauze group [(16.7 +/- 2.6) days, P < 0.01]. The pain scores during dressing change 5 and 10 days after grafting of the polyester gauze group were (3.2 +/- 0.8) and (4.9 +/- 0.4) respectively, both significantly lower than those of the vaseline oil gauze group [(5.1 +/- 0.6) and (8.2 +/- 0.5) respectively, both P < 0.01]. CONCLUSIONS Polyester gauze has quite good abilities to retain moisture and can promote the migration and proliferation of epithelial cells, relieves the pain caused by tearing of dressings off the wound, thus raising its acceptability. It is a relatively ideal carrier of skin grafting, as well as a new type of inner cover for the wound.

METHODS We enrolled in this study 42 patients with bladder transitional cell carcinoma, including Ta-T1 (n = 18), T2-T4 (n = 24), G1 (n = 12), G2 (n = 19), G3 (n = 11), metastasis (n =26) and non-metastasis (n = 16). Another 5 cases of normal bladder tissues were taken as controls, and the levels of MMP-2 and COX-2 mRNA were detected by RT-PCR. RESULTS The relative expressions of COX-2 mRNA were 1.038 +/- 0. 484 in Ta-T1, 1.489 +/- 0.584 in T2-T4, 0.920 +/- 0.442 in G1, 1.338 +/- 0.584 in G2 and 1.632 +/- 0.515 in G3, all significantly higher than that of the controls (0.460 +/- 0.224, P < 0.05). And the corresponding relative levels of MMP-2 mRNA were 1.107 +/- 0.384, 1.604 +/- 0.425, 0.971 +/- 0.370, 1.445 +/- 0.378 and 1.755 +/- 0.387, also significantly higher than that of the latter group (0.423 +/- 0.227, P < 0.05). The COX-2 and MMP-2 mRNA levels in the tumor tissues with and without metastasis were 1.591 +/- 0.455 vs 0.815 +/- 0.430 and 1.676 +/- 0.339 vs 0.927 +/- 0.228, (P < 0.01), respectively, with a positive correlation between the mRNA level of COX-2 and that of MMP-2 (r = 0. 703, P < 0.01). CONCLUSION MMP-2 and COX-2 mRNA are highly expressed in bladder transitional cell carcinoma tissues and their expressions are positively correlated with the degree of malignancy. MMP-2 and COX-2 might play a synergetic role in the pathogenesis and progression of bladder transitional cell carcinoma.

Abstract
The interactions of kaempferol and quercetin with intravenous immunoglobulin (IVIG) were studied in vitro by spectroscopic methods including fluorescence spectra, Fourier transformation infrared (FT-IR) spectra and circular dichroism (CD) spectra. The binding parameters for the reactions calculated according to the Sips equation suggested that the bindings of IVIG to kaempferol and quercetin were characterized by two binding sites with the average affinity constants K(o) at 1.032 x 10(4) M(-1) and 1.849 x 10(4) M(-1), respectively. The binding of IVIG with quercetin is stronger than that of IVIG with kaempferol. They were of non-specific and weak drug-protein interactions. Docking was used to calculate the interaction modes between kaempferol and quercetin with IVIG. The secondary structural compositions of free IVIG and its kaempferol, quercetin complexes were calculated by the FT-IR difference spectra, self-deconvolution, second derivative resolution enhancement and the curve-fitting procedures of amide I band respectively, which are in good agreement with the analyses of CD spectra. The effect of 3'-OH substituent in quercetin is distinct between the interactions of IVIG with kaempferol and quercetin for the secondary structure of the protein. The observed spectral changes indicate a partial unfolding of the protein structure, but the typical beta structural conformation of IVIG is still retentive in the presence of both drugs in aqueous solution. The average binding distances between the chromophores of IVIG with kaempferol (4.30 nm) and quercetin (4.35 nm) were obtained on the basis of the theory of Förster energy transfer. IVIG can serve as transport protein (carrier) for kaempferol and quercetin.

Abstract
OBJECTIVE To study different viewpoints to the conclusion and treatment, And the following up factors concerning social effect after the judgment of forensic psychiatry. METHODS By letters, calls, visits and by investigation forms made by myself, 208 testimonied cases were followed up separately from judicial organ or other organizations and institutes, individuals testimonied or their family members, victims and their family members. RESULTS Most testimonied individuals were married man of 30 years old or so whose average education were 4.84 years and testimonied by the public security organs. In criminal cases, violental criminals (129 cases, 83.77%) were much more than non-violental criminals (25 cases, 16.23%) and homicide criminals (44 cases, 28.57%) were most common in the former but civil cases were few. The rate of retstinvony was 2.93%. The testimonied individuals and their family members thought the condemn were appropriate (76.47%) for the people without criminal capacity and thought the condemn were appropriate (41.94%) or not appropriate (41.94%) for the people with criminal capacity. The opinions of the condemn for partial criminal capacity were between the former two cases. And they thought the condemn for 28 cases of non-guilty were appropriate (71.43%) and not appropriate (10.7%). 7 victims were dead. 10 victims were crippled. 10 victims restored to health. In 41 persons testimonied and set free with a verdict of "not guilty", 4 homicided again (4.87%), 2 set on fire (4.87%), 2 stealed (4.87%) and 3 had wrecked behavior (7.31%). CONCLUSION So it is suggested that the department concerned should keep criminals with mental disorder under control and treatment.

Abstract
Twenty-eight patients who suffered traumatic obsolete incomplete paralysis were treated with intradural lysis and peripheral nerve implantation by a microsurgery technique. The endorachis was opened and the fibrous bands adhering to the spinal cord from the arachnoid, pia mater spinalis, ligamenta denticulatum, and the initial part of the nerve root were completely relieved. The abnormal spinal cord was then opened by three to six incisions, which were each 0.1 mm to 0.2 mm deep and longer than the abnormal portion. A cyst found in the back or side of the spinal cord was opened and the liquid in it was drained. After that, the denuded spineurium and perineurium of the autogenous sural nerve were grafted, which makes the character and aspect of the nerve like the cauda equine. The nerve was longitudinally implanted into the incised spinal cord, and the cyst was waded with grafted nerve and at least one of them is ectropion sutured with the pia mater with 9-0 scatheless wire as a drain. Finally, the endorachis was covered by sacrospinal muscle flap. These patients were followed for 2 years to 8 years (average 3.5 years), and the sensibility and motion of each increased at least one grade. The strength of the main muscle was increased two grades and reached four grades in 11 patients, and the capability to walk was recovered. Relieving of the adhesion in the endorhachis, carving the cicatricial spinal cord, and implanting the autogenous peripheral nerve yields good results by initial clinical observation for traumatic obsolete and incomplete paralysis.

Abstract
Between February 1984 and September 1987, endoscopic embolization (EE) was performed in 26 patients with esophageal varices. The effects of EE were evaluated with endoscopic findings according to the general rules for recording endoscopic findings on esophageal varices as specified by the Japanese Research Society for Portal Hypertension. 1) When the result was regarded as effective if a patient had Cw, F1, R-C sign (-), Li and Lm or disappearance of varices, the improvement was found in 66.7% for Color, 79.2% for R-C sign, 54.2% for Form and 45.8% for Location after EE. 2) Recurrence of varices was found in 50% of the patients (12/24) and 4 of 12 cases (33.3%) had rebleeding. 3) When the endoscopic findings before and after EE were compared between relapsed and unrelapsed cases, relapsed patients had more unfavorable endoscopic findings, furthermore, the extent of improvements was also worse than that of unrelapsed cases. 4) As complications, slight fever, dysphagia and epigastric pain were found in most cases, however, all were cured conservatively. In conclusion, EE is useful and safety tool for the improvement of endoscopic findings of the patients with esophageal varices.
