Abstract
The increasing number of plant mitochondrial DNA genomes (mtDNA) sequenced reveals the extent of transfer from both chloroplast DNA genomes (cpDNA) and nuclear DNA genomes (nDNA). This study created a library and assembled the chloroplast and mitochondrial genomes of the leafy sweet potato better to understand the extent of mitochondrial and chloroplast gene transfer. The full-length chloroplast genome of the leafy sweet potato (OM808940) is 161,387 bp, with 132 genes annotated, including 87 protein-coding genes, 8 rRNA genes, and 37 tRNA genes. The mitochondrial genome (OM808941) was 269,578 bp in length and contained 69 functional genes, including 39 protein-coding genes, 6 rRNA genes, and 24 tRNA genes. 68 SSR loci were found in the leafy sweet potato organelle genome, including 54 in the chloroplast genome and 14 in the mitochondria genome. In the sweet potato mitochondrial genome, most genes have RNA editing sites, and the conversion ratio from hydrophilic amino acids to hydrophobic amino acids is the highest, reaching 47.12%. Horizontal transfer occurs in the sweet potato organelle genome and nuclear genome. 40 mitochondrial genome segments share high homology with 14 chloroplast genome segments, 33 of which may be derived from chloroplast genome horizontal transfer. 171 mitochondrial genome sequences come from the horizontal transfer of nuclear genome. The phylogenetic analysis of organelle genes revealed that the leafy sweet potato was closely related to the tetraploid wild species Ipomoea tabascana and the wild diploid species Ipomoea trifida.

Abstract
Objective: To investigate the study of the correlation between C-reactive protein to albumin ratio (CAR) and restenosis after stenting in patients with lower extremity atherosclerotic occlusive disease(LEASO). Methods: The clinical data of 95 patients with LEASO admitted to the Department of Vascular Surgery of Nanjing Drum Tower Hospital from June 2020 to December 2022 were retrospectively analyzed. There were 67 males and 28 females,aged (73.1±9.4) years (range:51 to 92 years). The patients were classified into the restenosis group (n=61) and the patency group (n=34) according to the CT angiography results. Independent sample t test,Mann-Whitney U test and χ2 test were used to compare the data between two groups. Risk factors for restenosis after femoropopliteal artery stenting in patients with LEASO were analyzed using multivariate Cox regression. The relationship between preoperative CAR level and restenosis after stent placement was analyzed. Subject operating characteristic(ROC) curves of CAR were plotted to assess the predictive value of CAR for restenosis after stenting,and the results were expressed as area under the curve (AUC). Results: The aortoiliac calcification grade,number of stents,length of stents,C-reactive protein and CAR levels in restenosis group were higher than those in the patency group,and the serum albumin level was lower than that in the patency group(all P<0.05). And the results of multifactorial Cox regression analysis showed that higher pre-procedure CAR level and lower ABI value was an independent risk factor for in-stent restenosis. The AUC of the ROC curve for restenosis was 0.737(95%CI:0.617 to 0.856),the AUC of the ROC curve for 12-month restenosis was 0.709(95%CI:0.602 to 0.815), and the AUC of the ROC curve for 24-month restenosis was 0.702(95%CI:0.594 to 0.811). Conclusion: Higher pre-procedural CAR levels in patients with LEASO is risk factor for in-stent restenosis,and CAR has a predictive value for restenosis after lower extremity arterial stent dilatation and angioplasty.

Abstract
Focused Ultrasound (FUS) paired with systemically-injected microbubbles (μB) is capable of transiently opening the blood-brain barrier (BBBO) for noninvasive and targeted drug delivery to the brain. FUS-BBBO is also capable of modulating the neuroimmune system, further qualifying its therapeutic potential for neurodegenerative diseases like Alzheimer's disease (AD). Natural aging and AD impose significant strain on the brain and particularly the BBB, modifying its structure and subsequently, its functionality. The emerging focus on treating neurodegenerative diseases with FUS-BBBO necessitates an investigation into the extent that age and AD affect the BBB's response to FUS. FUS-BBBO was performed with a 1.5-MHz, geometrically focused transducer operated at 450 kPa and paired with a bolus microbubble injection of 8 × 108 μB/mL. Here we quantify the BBBO, BBB closing (BBBC) timeline, and BBB permeability (BBBP) following FUS-BBBO in male mice with and without AD pathology, aged 10 weeks, one year, or two years. The data presented herein indicates that natural aging and AD pathology may increase initial BBBO volume by up to 34.4% and 40.7% respectively, extend BBBC timeline by up to 1.3 and 1.5 days respectively, and increase BBBP as measured by average Ktrans values up to 80% and 86.1% respectively in male mice. This characterization of the BBB response to FUS-BBBO with age and AD further clarifies the nature and extent of the functional impact of these factors and may offer new considerations for planning FUS-BBBO interventions in aged and AD populations.

Abstract
Objective: To investigate the regulatory effects of bio-intensity electric field on directional migration and microtubule acetylation in human epidermal cell line HaCaT, aiming to provide molecular theoretical basis for the clinical treatment of wound repair. Methods: The experimental research methods were used. HaCaT cells were collected and divided into simulated electric field group (n=54) placed in the electric field device without electricity for 3 h and electric field treatment group (n=52) treated with 200 mV/mm electric field for 3 h (the same treatment methods below). The cell movement direction was observed in the living cell workstation and the movement velocity, trajectory velocity, and direction of cosθ of cell movement within 3 h of treatment were calculated. HaCaT cells were divided into simulated electric field group and electric field treatment 1 h group, electric field treatment 2 h group, and electric field treatment 3 h group which were treated with 200 mV/mm electric field for corresponding time. HaCaT cells were divided into simulated electric field group and 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group treated with electric field of corresponding intensities for 3 h. The protein expression of acetylated α-tubulin was detected by Western blotting (n=3). HaCaT cells were divided into simulated electric field group and electric field treatment group, and the protein expression of acetylated α-tubulin was detected and located by immunofluorescence method (n=3). Data were statistically analyzed with Kruskal-Wallis H test,Mann-Whitney U test, Bonferroni correction, one-way analysis of variance, least significant difference test, and independent sample t test. Results: Within 3 h of treatment, compared with that in simulated electric field group, the cells in electric field treatment group had obvious tendency to move directionally, the movement velocity and trajectory velocity were increased significantly (with Z values of -8.53 and -2.05, respectively, P<0.05 or P<0.01), and the directionality was significantly enhanced (Z=-8.65, P<0.01). Compared with (0.80±0.14) in simulated electric field group, the protein expressions of acetylated α-tubulin in electric field treatment 1 h group (1.50±0.08) and electric field treatment 2 h group (1.89±0.06) were not changed obviously (P>0.05), while the protein expression of acetylated α-tubulin of cells in electric field treatment 3 h group (3.37±0.36) was increased significantly (Z=-3.06, P<0.05). After treatment for 3 h, the protein expressions of acetylated α-tubulin of cells in 100 mV/mm electric field group, 200 mV/mm electric field group, and 300 mV/mm electric field group were 1.63±0.05, 2.24±0.08, and 2.00±0.13, respectively, which were significantly more than 0.95±0.27 in simulated electric field group (P<0.01). Compared with that in 100 mV/mm electric field group, the protein expressions of acetylated α-tubulin in 200 mV/mm electric field group and 300 mV/mm electric field group were increased significantly (P<0.01); the protein expression of acetylated α-tubulin of cells in 300 mV/mm electric field group was significantly lower than that in 200 mV/mm electric field group (P<0.05). After treatment for 3 h, compared with that in simulated electric field group, the acetylated α-tubulin of cells had enhanced directional distribution and higher protein expression (t=5.78, P<0.01). Conclusions: Bio-intensity electric field can induce the directional migration of HaCaT cells and obviously up-regulate the level of α-ubulin acetylation after treatment at 200 mV/mm bio-intensity electric field for 3 h.

Abstract
INTRODUCTION We performed a meta-analysis to evaluate the effect of enhanced pharmaceutical recovery as postoperative standard care after radical cystectomy. METHODS A systematic literature search up to April 2021 was done and 33 studies included 6596 subjects submitted to surgery for radical cystectomy at the start of the study; 3143 of them received enhanced pharmaceutical recovery after surgery and 3453 were controls. The studies reported relationships about the effects of enhanced pharmaceutical recovery as postoperative standard care after radical cystectomy. We calculated the odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CIs) to assess the effects of enhanced pharmaceutical recovery as postoperative standard care after radical cystectomy using the dichotomous and continuous methods with a random or fixed-effect model. RESULTS Enhanced pharmaceutical recovery after surgery had significantly lower length of hospital stay (MD, -2.78; 95% CI, -3.59 to -1.97, p < 0.001), complications (OR, 0.75; 95% CI, 0.60-0.94, p = 0.01), readmission within 30 days (OR, 0.80; 95% CI, 0.69-0.94, p = 0.007), and time to defecation (MD, -1.30; 95% CI, -2.22 to -0.37, p = 0.006) compared to control in subjects submitted to radical cystectomy. CONCLUSIONS Enhanced pharmaceutical recovery after surgery may reduce the length of hospital stay, complications, readmission within 30 days, and time to first bowel movement compared to control in subjects with surgery for radical cystectomy. Furthers studies are required to validate these findings.

Abstract
Objective: To investigate the regulatory effects of bio-intensity electric field on the transformation of human skin fibroblasts (HSFs). Methods: The experimental research methods were used. HSFs were collected and divided into 200 mV/mm electric field group treated with 200 mV/mm electric field for 6 h and simulated electric field group placed in the electric field device without electricity for 6 h. Changes in morphology and arrangement of cells were observed in the living cell workstation; the number of cells at 0 and 6 h of treatment was recorded, and the rate of change in cell number was calculated; the direction of cell movement, movement velocity, and trajectory velocity within 3 h were observed and calculated (the number of samples was 34 in the simulated electric field group and 30 in 200 mV/mm electric field group in the aforementioned experiments); the protein expression of α-smooth muscle actin (α-SMA) in cells after 3 h of treatment was detected by immunofluorescence method (the number of sample was 3). HSFs were collected and divided into simulated electric field group placed in the electric field device without electricity for 3 h, and 100 mV/mm electric field group, 200 mV/mm electric field group, and 400 mV/mm electric field group which were treated with electric fields of corresponding intensities for 3 h. Besides, HSFs were divided into simulated electric field group placed in the electric field device without electricity for 6 h, and electric field treatment 1 h group, electric field treatment 3 h group, and electric field treatment 6 h group treated with 200 mV/mm electric field for corresponding time. The protein expressions of α-SMA and proliferating cell nuclear antigen (PCNA) were detected by Western blotting (the number of sample was 3). Data were statistically analyzed with Mann-Whitney U test, one-way analysis of variance, independent sample t test, and least significant difference test. Results: After 6 h of treatment, compared with that in simulated electric field group, the cells in 200 mV/mm electric field group were elongated in shape and locally adhered; the cells in simulated electric field group were randomly arranged, while the cells in 200 mV/mm electric field group were arranged in a regular longitudinal direction; the change rates in the number of cells in the two groups were similar (P>0.05). Within 3 h of treatment, the cells in 200 mV/mm electric field group had an obvious tendency to move toward the positive electrode, and the cells in simulated electric field group moved around the origin; compared with those in simulated electric field group, the movement velocity and trajectory velocity of the cells in 200 mV/mm electric field group were increased significantly (with Z values of -5.33 and -5.41, respectively, P<0.01), and the directionality was significantly enhanced (Z=-4.39, P<0.01). After 3 h of treatment, the protein expression of α-SMA of cells in 200 mV/mm electric field group was significantly higher than that in simulated electric field group (t=-9.81, P<0.01). After 3 h of treatment, the protein expressions of α-SMA of cells in 100 mV/mm electric field group, 200 mV/mm electric field group, and 400 mV/mm electric field group were 1.195±0.057, 1.606±0.041, and 1.616±0.039, respectively, which were significantly more than 0.649±0.028 in simulated electric field group (P<0.01). Compared with that in 100 mV/mm electric field group, the protein expressions of α-SMA of cells in 200 mV/mm electric field group and 400 mV/mm electric field group were significantly increased (P<0.01). The protein expressions of α-SMA of cells in electric field treatment 1 h group, electric field treatment 3 h group, and electric field treatment 6 h group were 0.730±0.032, 1.561±0.031, and 1.553±0.045, respectively, significantly more than 0.464±0.020 in simulated electric field group (P<0.01).

Abstract
OBJECTIVE To investigate the relationship between the expression of receptor for advanced glycation end products (RAGE) and high-mobility group box-1 (HMGB1) and the clinical and pathological parameters and prognosis of the patients with gastric cancer (GC) with diabetes mellitus (DM). PATIENTS AND METHODS 30 normal gastric mucosa, 30 tissues with GC, 90 tissues with GC and DM and their clinical data were collected. The expression levels of RAGE and HMGB1 were detected by immunohistochemistry. Kaplan-Meier survival curve was used to analyze the relationship between the expression levels of RAGE and HMGB1 and the 5-year survival rate. MTT and cell scratch assays were used to detect the effects of knockdown RAGE and HMGB1 on the proliferation and migration of BGC-823 cells. Real-Time PCR was used to detect the regulation of RAGE and HMGB1 on PTBP-1, and Spearman correlation analysis was performed to analyze the correlation between RAGE and HMGB1 and Polyprimidine tract protein (PTBP-1). RESULTS Compared with the normal gastric mucosa group, the expression levels of RAGE and HMGB1 were significantly higher in the GC group, GC with DM group. The expression of RAGE and HMGB1 was related with lymph node metastasis, TNM staging, and tumor invasion (p<0.05). Age, TNM stage, tumor infiltration depth, the expression of RAGE and HMGB1 were related with prognosis of patients with GC and DM (p<0.05). Tumor infiltration depth, the expression of RAGE and HMGB1 could affect the 5-year survival rate of patients with GC and DM (p<0.05). CONCLUSIONS Knockdown RAGE and HMGB1 increased the expression of PTBP-1, and RAGE and HMGB1 were negatively regulated with PTBP-1. RAGE and HMGB1 are independent risk factors for the prognosis of patients with GC with DM. RAGE and HMGB1 may regulate the expression of PTBP-1 and inhibit the glycolysis of cells, which may affect the cell proliferation and migration of GC.

Abstract
PURPOSE PIM kinase is called proto-oncogene, but there are less research on PIM family in colon cancer. This study was designed to explore the prognosis of PIM3 in colon cancer. METHODS In this study, we downloaded RNA-seq and clinical information of colon cancer from the Gene Expression Omnibus (GEO) database. Kaplan-Meier method was used for analyzing the impact of PIM3 on the survival of patients with colon cancer. Single-factor and multi-factor cox regression analysis were used for verifying the prognostic value of PIM3. Spearman correlation analysis was used for screening PIM3 related genes. Functional enrichment analysis was used for analyzing the biological functions and pathways in which PIM3 related genes may be involved. STRING online tools were used for building a co-expression network. Cytoscape was used for co-expression network visualization. RESULTS Compared with the low expression group, the patients in the PIM3 high expression group lived longer time. Single-factor and multi-factor cox regression analysis indicated that PIM3 was an independent prognostic factor for colon cancer. Sixty-two PIM3 related genes were screened, and GO and KEGG enrichment analyses suggested that PIM3 related genes might be involved in the MAPK and WNT pathways. The co-expression network showed a strong correlation between PIM3 and MLKL, MYL5, PPP3R1 and other genes. CONCLUSIONS PIM3 is an independent prognostic factor of colon cancer and may be a target for the diagnosis and treatment of colon cancer.

Abstract
OBJECTIVE Accumulating studies have reported that circular RNAs (circRNAs) can act as novel prognostic biomarkers in multiple malignant tumors. Here, we conducted a study to investigate the potential function and molecular mechanism of action of hsa_circ_0010882 in gastric cancer (GC). PATIENTS AND METHODS The expression of hsa_circ_0010882 in the plasma of GC patients and in GC cell lines was verified by qRT-PCR. Its association with overall survival of GC patients was then analyzed by statistical analysis. Gain-of-function and loss-of-function assays were used to investigate the physiological function of hsa_circ_0010882 in GC cells in vitro in the context of proliferation, apoptosis, migration, and invasion. Moreover, the molecular mechanism of action of hsa_circ_0010882 was predicted using online databases and a literature review. A Western blot assay was used to detect the levels of proteins in the PI3K/Akt/mTOR signaling pathway. RESULTS We found that hsa_circ_0010882 expression was significantly upregulated in the plasma of GC patients and GC cell lines. Increased expression of hsa_circ_0010882 was significantly correlated with tumor size and histological grade. In addition, GC patients with higher expression of hsa_circ_0010882 had significantly lower overall survival than patients with lower expression of hsa_circ_0010882. Multivariate analysis showed that hsa_circ_0010882 expression could be an independent prognostic factor for overall survival. The proliferation, migration, and invasiveness of GC cell lines were inhibited following hsa_circ_0010882 knock-down, while GC cellular apoptosis increased. Further, overexpression of hsa_circ_0010882 leads to increased proliferation, migration, and invasiveness of GC cell lines. While apoptosis was higher in the GC cell line group with low expressing hsa_circ_0010882 than the control group, no significant difference in apoptosis was detected between the hsa_circ_0010882 overexpressing and the control group. Finally, a mechanistic analysis demonstrated that the hsa_circ_0010882 was positively associated with PI3K/Akt/mTOR signaling pathway. CONCLUSIONS Hsa_circ_0010882, as an oncogenic molecule, is highly expressed in the plasma of patients with GC and is associated with poor prognosis. It plays an important role in proliferation, migration, and invasive genotypes of GC cell lines via regulation of the PI3K/Akt/mTOR signaling pathway. Additionally, it might be a potential prognostic biomarker for GC patients.

Abstract
OBJECTIVE The aim of this study was to explore the expression level of Wnt1-inducible signaling pathway protein 1 (WISP1) and its clinical significance in hepatocellular carcinoma (HCC). PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was performed to detect the expression level of WISP1 in HCC tissues and cells. Kaplan-Meier curves and Cox proportional hazard regression model were chosen for single and multiple factor analysis of survival analysis, respectively. Furthermore, wound healing assay and transwell assay were used to verify the effect of WISP1 on HCC cell metastasis in vitro. RESULTS The expression level of WISP1 in HCC tissues was significantly higher than that in para-cancer tissues (p<0.05). WISP1 expression was positively correlated with lymph node metastasis and clinical stage of HCC. Kaplan-Meier curve showed that HCC patients with higher WISP1 expression exhibited significantly worse progression free survival (PFS) time and overall survival (OS) time. Both univariate and multivariate analysis indicated that high expression of WISP1 was an independent predictor of poor prognosis in HCC. In addition, WISP1 significantly promoted the invasion and migration of HCC cells in vitro. CONCLUSIONS WISP1 might contribute to the development of HCC, serving as a clinical biomarker and therapeutic target for HCC patients.

Abstract
INTRODUCTION Oesophageal carcinoma is the sixth most lethal cancer in the world. At present, the choice of specific surgical methods is controversial. This study compares the safety and efficacy of endoscopic submucosal dissection and endoscopic mucosal resection in treating early oesophageal carcinoma. METHODS We carried out a search of online databases including the Web of Science, PubMed, Embase and the Cochrane Library with no language restrictions. The inclusion criteria were patients with early oesophageal carcinoma who accepted the treatment of endoscopic submucosal dissection compared with endoscopic mucosal resection. FINDINGS A total of 1,462 patients with 1,650 lesions from nine studies were included in the meta-analysis. When compared with the endoscopic mucosal resection group, the en bloc resection (endoscopic submucosal dissection 67.94% vs endoscopic mucosal resection 52.78%; odds ratio 19.79, p = 0.000) and complete resection (endoscopic submucosal dissection 75.57% vs endoscopic mucosal resection 59.47%; odds ratio 16.10, p = 0.000) rates were significantly higher in the endoscopic submucosal dissection group, while the local recurrence rate was significantly lower in the endoscopic submucosal dissection group (endoscopic submucosal dissection 0.08% vs endoscopic mucosal resection 2.66%; odds ratio 0.08, p = 0.000). The incidence of complications and procedural time were also tested.

Abstract
Intestinal mucositis is a frequent side effect in cancer patients who are treated with chemotherapy. There are no effective treatment strategies to date. To find a novel way to alleviate mucositis, the effects of selenium-enriched Bifidobacterium longum (Se-B. longum) in preventing irinotecan (CPT-11)-induced intestinal mucositis in a mouse model were investigated. We tested the ability of Se-B. longum (Se 0.6 mg/kg, 5×108 cfu/mice) to reduce small intestinal mucositis induced by CPT-11 (75 mg/kg, daily) injected intraperitoneally for four consecutive days in mice. Se-B. longum significantly decreased mortality induced by CPT-11 from 71.4% to 16.7%. CPT-11 induced body weight loss, which was alleviated by preventative and simultaneous administration of Se-B. longum. Se-B. longum significantly decreased the severity of diarrhoea from 11 to 4% compared to the CPT-11 group. Inflammation, including intestinal shortening and upregulation of tumour necrosis factor-α and interleukin-1β induced by CPT- 11, were prevented by Se-B. longum. Se-B. longum is effective in preventing small intestinal mucositis induced by CPT-11 and therefore has potential to be used clinically by cancer patients.

Abstract
Ultrasonic frequency is one of the most important parameters that decides the characteristics of acoustic cavitation. Low- (16-50 kHz) and high- (≥200 kHz) frequency ultrasounds present opposite physical and chemical behaviors and have been extensively studied, yet frequencies in between are poorly characterized. In this study, acoustic cavitation at the intermediate ultrasonic frequency of 100 kHz is compared with that at 20 kHz and at 362 kHz by different experimental investigations: sonochemical yield (H2O2), images of sonochemiluminescence and sonoluminescence, as well as sonoluminescence spectra in aqueous media saturated with Ar or Ar/(20 vol %)O2. The chemical activity (H2O2 yield) of cavitation bubbles at 100 kHz presents a transitional behavior between low and high frequencies. The active cavitation zone distributes in the whole sonicated volume, similarly to high-frequency ultrasound and much further than at 20 kHz. The spectral shape of 100 kHz spectra is similar to that at 20 kHz. On the contrary, 100 kHz ultrasound provides the dissociation of O2 and N2 molecules inside the bubble, which is more typical for high-frequency ultrasound. This faculty is explained by the more extreme conditions reached at collapse compared with 20 kHz. Rovibronic temperatures of OH (A2Σ+) excited radicals derived from spectroscopic simulations confirm this interpretation.

Abstract
The aim of this study was to determine whether local scrotal heating (42°C, for 1 hr) had an effect on the expression of tight junction (TJ)-associated molecule Occludin in boar testes. Adult boars (Landrace, n = 6) were used and randomly divided into two groups (n = 3 each). Three boars were given local scrotal exposure to 42°C for approximately 1 h with a home-made electric blanket of controlled temperature as local scrotal heating group, the other three boars received no heat treatment and were left at standard room temperature as control group. After 6 hr, all boars were castrated and the testes were harvested. qRT-PCR, Western blotting and immunohistochemistry were used to explore the expression and localization of Occludin. qRT-PCR and Western blotting showed that the protein and mRNA levels of Occludin significantly decreased in local scrotal heating group as compared to the control. Furthermore, immunoreactivity staining of Occludin was localized at the sites of the blood-testis barrier (BTB) and formed an almost consecutive and strong immunoreactivity strand in the control, while Occludin was limited to Sertoli cells (SCs) and no obvious immunoreactivity strand was present in local scrotal heating group. These data indicated that local scrotal heating decreased the expression of TJ-associated molecule Occludin, which may be involved in heat-induced spermatogenesis damage.

Abstract
Objective: To analyze the objective characteristics of roll test and Dix-Hallpike test in benign paroxysmal positional vertigo(BPPV)patients, discussing the premier solution of positional test. Methods: A total of 230 patients with BPPV, whereas 170 posterior semicircular canal canalithiasis (PSC-Can) BPPV and 60 horizontal semicircular canal canalithiasis (HSC-Can) BPPV were involved respectively. The induced nystagmus in roll test and Dix-Hallpike test was recorded by video nystagmuo graph (VNG), and the direction, intensity and time characteristics of nystagmus were compared in various BPPV.SPSS19.0 software was used for statistical analysis. Results: Vertically upward nystagmus was induced by hanging in 170 PSC-Can Dix-Hallpike test, and the nystagmus reversed and turned weaker when the subjects came to sit. The intensity of nystagmus at turning to lesion side by hanging and sitting were (30.3±14.1)°/s and (12.6±7.5)°/s respectively, the difference was statistically significant (t=20.153, P<0.05). However, no nystagmus was induced in PSC-Can roll test. Horizontal nystagmus in the same direction with turning was induced in 60 HSC-Can roll test. The intensity of nystagmus at turning to lesion side and normal side was (42.0±18.0)°/s and (20.3±8.7)°/s respectively, the difference was statistically significant (t=12.731, P<0.05). Furthermore, horizontal nystagmus in the same direction with turning was induced in 57 HSC-Can Dix-Hallpike. The coherence was 95% with the results of roll test. Conclusions: Dix-Hallpike test can not only be used to diagnose PSC-Can, but also induce nystagmus in HSC-Can effectively. Whereas the roll test only show significance in diagnosing HSC-Can. To avoid uncomfortable stimulation to patients as much as possible, we suggest to use Dix-Hallpike test at first, and to judge whether using roll test based on the result of the horizontal nystagmus.

Abstract
The Bactrian camel includes various domestic (Camelus bactrianus) and wild (Camelus ferus) breeds that are important for transportation and for their nutritional value. However, there is a lack of extensive information on their genetic diversity and phylogeographic structure. Here, we studied these parameters by examining an 809‐bp mtDNA fragment from 113 individuals, representing 11 domestic breeds, one wild breed and two hybrid individuals. We found 15 different haplotypes, and the phylogenetic analysis suggests that domestic and wild Bactrian camels have two distinct lineages. The analysis of molecular variance placed most of the genetic variance (90.14%, P < 0.01) between wild and domestic camel lineages, suggesting that domestic and wild Bactrian camel do not have the same maternal origin. The analysis of domestic Bactrian camels from different geographical locations found there was no significant genetic divergence in China, Russia and Mongolia. This suggests a strong gene flow due to wide movement of domestic Bactrian camels.

Abstract
To assess the phytoremediation potential of an autochthonous willow (Salix × aureo-pendula CL 'J1011') for phenanthrene (PHE)-contaminated soils and PHE-cadmium (PHE-Cd) co-contaminated soils, we conducted field experiments in the lower reaches of the Yangtze River, China. Ethylenediaminetetraacetic acid (EDTA) and ethyl lactate were tested for individual and combined effects on the phytoremediation efficiency. For PHE-contaminated soils, willow plus ethyl lactate resulted in significant removal of PHE from soils after 45 days, and the PHE concentration in the shoots was significantly higher with than without ethyl lactate. For PHE-Cd co-contaminated soils, both willow plus EDTA and willow plus EDTA and ethyl lactate led to a significant decrease in the concentrations of PHE and Cd in the soils after 45 days, whereas willow alone did not. The PHE and Cd concentrations in the willow shoots were significantly enhanced in the presence of EDTA alone and with ethyl lactate, except for the PHE concentration in stems with EDTA alone. Under the same treatment, the presence of Cd had no significant influence on the PHE removal from soils. The results indicate the feasibility of using this willow together with both EDTA and ethyl lactate for the simultaneous removal of PHE and Cd from soils.

Abstract
A novel design of decorating microsphere surface with concentric rings to modulate the photonic nanojet (PNJ) is investigated. By introducing the concentric ring structures into the illumination side of the microspheres, a reduction of the full width at half maximum (FWHM) intensity of the PNJ by 29.1%, compared to that without the decoration, can be achieved numerically. Key design parameters, such as ring number and depth, are analyzed. Engineered microsphere with four uniformly distributed rings etched at a depth of 1.2 μm and width of 0.25 μm can generate PNJ at a FWHM of 0.485 λ (λ = 400nm). Experiments were carried out by direct observation of the PNJ with an optical microscope under 405 nm laser illumination. As a result, shrinking of PNJ beam size of 28.0% compared to the case without the rings has been achieved experimentally. Sharp FWHM of this design can be beneficial to micro/nanoscale fabrication, optical super-resolution imaging, and sensing.

Abstract
Published data on the association between the cytotoxic T-lymphocyte-associated antigen-4 gene A49G polymorphism and the risk for Hashimoto's thyroiditis (HT) are inconclusive. A meta-analysis was performed to derive a more precise estimation. Published case-control studies in English or Chinese were identified. In total, 24 studies with 2295 cases and 4521 controls were investigated. A random-effect model was performed irrespective of between-study heterogeneity. Study quality was assessed in duplicate, and subgroup analyses were conducted by ethnicity or age. Overall, the 49G allele was associated with an increase in HT risk [odds ratio (OR) = 1.31; 95% confidence interval (95%CI) = 1.17-1.47; P < 0.00001]. In a subgroup analysis by ethnicity, comparison of allele 49G with 49A generated a 27% increased risk among East Asians (OR = 1.48; 95%CI = 1.24-1.76; P < 0.00001) and whites (OR = 1.27; 95%CI = 1.12-1.44; P = 0.0002). We also found an increased risk among adults (OR = 1.31; 95%CI = 1.17-1.47; P < 0.00001) but not among children (OR = 1.44; 95%CI = 0.75-2.79; P = 0.27), possibly owing to the small sample sizes in children. No publication biases were observed. This meta-analysis suggested that the cytotoxic T-lymphocyte-associated antigen-4 gene 49G allele was associated with an increased HT risk, especially in adults.

Abstract
BACKGROUND AND PURPOSE Prostaglandin E(2) (PGE(2)) stimulation of the G protein-coupled prostanoid EP(1) receptor was found to up-regulate the expression of Nur-related factor 1 (Nurr1) (NR4A2), a transcription factor in the NR4A subfamily of nuclear receptors. The present studies characterize the molecular mechanism of this up-regulation. EXPERIMENTAL APPROACH The expression of Nurr1 was examined by immunoblot analysis, the polymerase chain reaction and reporter gene assays in human embryonic kidney (HEK) cells stably expressing the recombinant EP(1) receptor and in SH-SY5Y neuroblastoma cells expressing endogenous EP(1) receptors. Signalling pathway inhibitors were used to examine the roles of Rho, PKA, the cAMP response element binding protein (CREB) and NF-κB on the PGE(2) stimulated up-regulation of Nurr1. CREB and NF-κB signalling were also examined by immunoblot analysis and reporter gene assays. KEY RESULTS The EP(1) receptor mediated up-regulation of Nurr1 was blocked with inhibitors of Rho, PKA, NF-κB and CREB; but PGE(2) failed to significantly stimulate intracellular cAMP formation. PGE(2) stimulation of the EP1 receptor induced the phosphorylation and activation of CREB and NF-κB, which could be blocked by inhibition of PKA. CONCLUSIONS AND IMPLICATIONS PGE(2) stimulation of the human EP(1) receptor up-regulates the expression of Nurr1 by a mechanism involving the sequential activation of the Rho, PKA, CREB and NF-κB signalling pathways. EP(1) receptors are implicated in tumorigenesis and the up-regulation of Nurr1 may underlie the anti-apoptotic effects of PGE(2) .

Abstract
BACKGROUND AND STUDY AIM The real-time identification and removal of adenomas is a cost-effective strategy to improve the prognosis of colorectal cancer. Confocal laser endomicroscopy (CLE) could provide real-time histological-level observation. We aimed to evaluate the efficacy of CLE diagnosis using a simple classification system that differentiates adenomas from non-neoplastic polyps with intravenous fluorescein staining alone. PATIENTS AND METHODS An endoscope integrated confocal laser microscopy system was used in this study. CLE images of 35 colonic polyps, including 15 hyperplastic polyps and 20 adenomas confirmed by histology, were first evaluated to develop criteria for diagnosis of neoplastic and non-neoplastic polyps. The diagnostic criteria included goblet cell depletion, villous architecture, and microvascular alterations. We then performed a prospective study of colonic polyps found during CLE and classified them according to the established criteria. A total of 115 patients with 115 colonic polyps were included. The real-time CLE diagnosis was compared with that from histology. The stored CLE images were evaluated later by a blinded observer. RESULTS The sensitivity, specificity, positive predictive value, and negative predictive value of real-time CLE in identifying colonic adenomas were 93.9 % (95 % confidence interval [CI] 85.4 - 97.6), 95.9 % (95 % CI 86.2 - 98.9), 96.9 % (95 % CI 89 - 99), and 92.2 % (95 % CI 81 - 97), respectively, compared with histological results. Interobserver agreement between real-time and post-CLE still-image evaluation was excellent (kappa = 0.929). Goblet cell depletion alone had a sensitivity of 84.9 % (95 % CI 73 - 92) and a specificity of 87.8 % (95 % CI 75 - 95), as well as excellent interobserver agreement (kappa = 0.824). CONCLUSIONS Endoscope integrated CLE with fluorescein staining may reliably assist in the real-time identification of colonic adenomas. Among three diagnostic categories, goblet cell depletion can be used to distinguish adenomas and hyperplastic polyps.

Abstract
Iron (III) doped titanium dioxide film with high visible light photocatalytic activity was prepared using the modified sol-gel method, in which, none of organic solvent was used and all the films were prepared at low temperature. The as prepared films were characterized by wide angle X-ray diffraction (XRD), UV-visible diffuse reflectance spectroscopy (DRS), electron paramagnetic resonance (EPR) and atomic force microscope (AFM). Characteristic results clearly show that the architecture of Fe3+ doped TiO2 is composed of mixed-phase crystal textures of anatase and brookite, and crystal size keeps at approximately 10 nm. After Fe (III) was successfully doped into titania lattice and partly substituted Ti (IV), absorbance of films in visible light displays obvious red shift. The photocatalytic activities of Fe3+ doped TiO2 films show their best efficiency at an optimal atomic ratio of Fe to Ti of 1.2:100. The effect of dopant and preparing conditions on their structure and photocatalytic activities were investigated in detail.

Abstract
The evolutionary relationship between the domestic bactrian camel and the extant wild two-humped camel and the factual origin of the domestic bactrian camel remain elusive. We determined the sequence of mitochondrial cytb gene from 21 camel samples, including 18 domestic camels (three Camelus bactrianus xinjiang, three Camelus bactrianus sunite, three Camelus bactrianus alashan, three Camelus bactrianus red, three Camelus bactrianus brown and three Camelus bactrianus normal) and three wild camels (Camelus bactrianus ferus). Our phylogenetic analyses revealed that the extant wild two-humped camel may not share a common ancestor with the domestic bactrian camel and they are not the same subspecies at least in their maternal origins. Molecular clock analysis based on complete mitochondrial genome sequences indicated that the sub-speciation of the two lineages had begun in the early Pleistocene, about 0.7 million years ago. According to the archaeological dating of the earliest known two-humped camel domestication (5000-6000 years ago), we could conclude that the extant wild camel is a separate lineage but not the direct progenitor of the domestic bactrian camel. Further phylogenetic analysis suggested that the bactrian camel appeared monophyletic in evolutionary origin and that the domestic bactrian camel could originate from a single wild population. The data presented here show how conservation strategies should be implemented to protect the critically endangered wild camel, as it is the last extant form of the wild tribe Camelina.

Abstract
The degradation of radiolabeled 4(3',5'-dimethyl-3'-heptyl)-phenol [nonylphenol (NP)] was tested with resting cells of Sphingomonas sp. strain TTNP3. Concomitantly to the degradation of NP, a metabolite identified as hydroquinone transiently accumulated and short-chain organic acids were then produced at the expense of hydroquinone. Two other radiolabeled isomers of NP, 4(2',6'-dimethyl-2'-heptyl)-phenol and 4(3',6'-dimethyl-3'-heptyl)-phenol, were synthesized. In parallel experiments, the 4(2',6'-dimethyl-2'-heptyl)-phenol was degraded more slowly than the other isomers of NP by strain TTNP3, possibly because of effects of the side-chain structure on the kinetics of degradation. Alkylbenzenediol and alkoxyphenol derivatives identified as metabolites during previous studies were synthesized and tested as substrates. The derivatives were not degraded, which indicated that the mineralization of NP does not proceed via alkoxyphenol as the principal intermediate. The results obtained led to the elucidation of the degradation pathway of NP isomers with a quaternary alpha-carbon. The proposed mechanism is a type II ipso substitution, leading to hydroquinone and nonanol as the main metabolites and to the dead-end metabolites alkylbenzenediol or alkoxyphenol, depending on the substitution at the alpha-carbon of the carbocationic intermediate formed.
