Abstract
OBJECTIVE To compare the pain control efficiency of continuous adductor canal block (ACB) and femoral nerve block (FNB) in total knee arthroplasty. METHODS From April to September 2016, patients with severe knee osteoarthritis undergoing primary unilateral total knee arthroplasty (TKA) were prospectively observed, and all the patients were randomized received ultrasound-guided continuous ACB or FNB after surgery. Numeric pain rating scales(NPRS)pain scores in rest and activity 2, 6, 12, 24 and 48 h after surgery were collected, and the preoperative and postoperative quadriceps strength at 24 and 48 h were analyzed. Opioids consumption and anesthesia related adverse effects were also recorded. RESULTS In the study, 40 patients were enrolled, with 20 patients in each group, male:female=7:33, the age: (63.8±10.1) years, and the body mass index (BMI): (28.5±3.5) kg/m(2).The general conditions were comparable between the two groups. Though the rest pain 2 h after surgery [ACB=0.0(0,6), FNB=3.0(0,5), P=0.004] and activity pain 12 h post operation [ACB=3.0(3,0), FNB=5.5(0,10), P=0.004] were lower in ACB group compared with FNB group, there was no statistical difference in the other pain checking points between the two groups. The quadriceps strength 24 h and 48 h after surgery were(85.3±27.6) N and (80.0±30.1) N in ACB group, (69.0±29.4) N and (64.4±32.0) N in FNB group, both of them were declined by time. The exact data were higher in ACB group, however, there was no statistical difference between the two group by repeated measurements variance analysis(F=2.703, P=0.108).Four patients in ACB group and five in FNB acquired additional use of dolantin once (100 mg/per time) within 24 h. And among them, three patients acquired once dolantin in ACB, two in FNB, from 24 to 48 h postoperation. There were five patients who suffered nausea postoperation in ACB group, and one who reported xerostomia. Four patients in FNB had nausea with vomiting, and three experienced xerostomia. Deep vein thrombosis appeared in 2 patients in FNB group, but no one in ACB group. CONCLUSION Continuous ACB is not superior in pain control after TKA compared with FNB, and the quadriceps strength could be reserved more by this method, which performed early benefits in fast rehabilitation.

Abstract
Zoonoses are increasingly recognized as an important burden on global public health in the 21st century. High-resolution, long-term field studies are critical for assessing both the baseline and future risk scenarios in a world of rapid changes. We have used a three-decade-long field study on hantavirus, a rodent-borne zoonotic pathogen distributed worldwide, coupled with epidemiological data from an endemic area of China, and show that the shift in the ecological dynamics of Hantaan virus was closely linked to environmental fluctuations at the human-wildlife interface. We reveal that environmental forcing, especially rainfall and resource availability, exert important cascading effects on intra-annual variability in the wildlife reservoir dynamics, leading to epidemics that shift between stable and chaotic regimes. Our models demonstrate that bimodal seasonal epidemics result from a powerful seasonality in transmission, generated from interlocking cycles of agricultural phenology and rodent behavior driven by the rainy seasons.

Abstract
Dengue transmission in urban areas is strongly influenced by a range of biological and environmental factors, yet the key drivers still need further exploration. To better understand mechanisms of environment-mosquito-urban dengue transmission, we propose an empirical model parameterized and cross-validated from a unique dataset including viral gene sequences, vector dynamics and human dengue cases in Guangzhou, China, together with a 36-year urban environmental change maps investigated by spatiotemporal satellite image fusion. The dengue epidemics in Guangzhou are highly episodic and were not associated with annual rainfall over time. Our results indicate that urban environmental changes, especially variations in surface area covered by water in urban areas, can substantially alter the virus population and dengue transmission. The recent severe dengue outbreaks in Guangzhou may be due to the surge in an artificial lake construction, which could increase infection force between vector (mainly Aedes albopictus) and host when urban water area significantly increased. Impacts of urban environmental change on dengue dynamics may not have been thoroughly investigated in the past studies and more work needs to be done to better understand the consequences of urbanization processes in our changing world.

Abstract
Objective: To assess the pain control efficiency of continuous adductor canal block in total knee arthroplasty. Methods: From October to December 2015, patients with severe knee osteoarthritis undergoing primary unilateral TKA were observed clinically.All of the patients received ultrasound-guided continuous adductor canal block after surgery.NPRS Pain score in rest and activity at 2, 6, 12, 24, 48 h after surgery were collected, preoperative and postoperative quadriceps strength at 24, 48 h were analyzed. Opioids consumption and anesthesia related adverse effects were also recorded. Results: All of the patients were enrolled. Rest pain control was fairly good(1.8±1.5), (2.4±1.5), (2.7±1.3), (2.7±1.7), (2.3±1.4) score, but the patients were not satisfied with activity pain control(3.1±2.1), (3.1±2.1), (4.2±2.2), (4.7±2.5), (6.2±2.4) score. There were statistically differences comparing the NPRS in rest pain with the score in activity, except for the results between each other at 6 hours (P=0.252>0.05)after surgery.The results showed no significant differences comparing quadriceps strengthpreoperatively with 24, 48 h postoperatively by repeated measurements variance analysis.Eight patients acquired additional use of dolantin once (100 mg/per time) within 24 h and among them three patients acquired once dolantin during 24 to 48 h. Eleven patients complained nausea postoperatively, one reported vomiting and one experienced xerostomia. Conclusion: Ultrasound-guided continuous adductor canal block can reduce resting pain after TKA, but has a limited effect in activity pain control.Quadriceps strength had been spared after ACB, which might performearly benefits in rehabilitation. ACB-related complications need further observation to be defined.

Abstract
AIMS A low yield of bacterial cellulose (BC) always results from an excessive accumulation of organic acids. Screening and the selection of bacterial mutants with a low accumulation of organic acids is an efficient approach for improving BC production. METHODS AND RESULTS In combination with the proton suicide method (medium containing NaBr-NaBrO3 ), diethyl sulphate chemical mutagenesis coupled with 60 Co-γ irradiation treatment were performed for the screening and selection of desired mutant lines with a high yield of BC. Two high-yield strains, Br-3 and Co-5, as well as a low-yield strain, Br-12, were obtained. Amplified fragment length polymorphism (AFLP) was applied to explore the differences between the mutant lines and the wild type. For the Br-12 line, three specific fragments were verified, corresponding to TonB-dependent transport (TBDT), exopolysaccharides output protein (PePr) and an unknown gene. For Co-5, two specific fragments were matched, acsD and UDP-galactose-4-epimerase. In addition, metabolic analysis for the mutant lines indicated that BC production may be limited by excessive accumulation of organic acids in the fermentation. The limitation would be resolved by the cross-talk of genes involved in BC biosynthesis. CONCLUSIONS Reduced organic acid by-products from glucose in bypasses were found to be responsible for the high-yield BC synthesis in Komagataeibacter hansenii mutant strains. SIGNIFICANCE AND IMPACT OF THE STUDY The metabolic process was varied by mutagenesis-induced gene disruption of the metabolic products. A new idea was provided for the targeted screening and characterization of mutants in the future.

Abstract
Human infection with avian influenza virus A(H10N8) was initially reported in China in December 2013. We characterized H10N8 strains from a human patient and from poultry in live markets that infected persons had visited. Results of genome sequencing and virus characterization suggest that the virus strains that infected humans originated from these markets.

Abstract
OBJECTIVE The aim of the study was to evaluate the association of fasting plasma glucose (FPG) level over 5.3 mmol/L to the development of abnormal glucose metabolism and cardiovascular diseases (CVD). METHODS This was a retrospective cohort study with 1 064 non-diabetic subjects(980 males; 84 females) aged 60 or over, who carried out annual health check-up in Chinese PLA General Hospital from May, 1996 to May, 2015. Based on the average FPG level of 3 years before enrollment, the subjects were divided into four groups: <5.3 mmol/L, 5.3-<5.6 mmol/L, 5.6-<6.1 mmol/L and 6.1-<7.0 mmol/L. Glucose metabolic changes, complications and mortality were follow-up until May, 2015. RESULTS (1)The initial 3-year average FPG levels were (4.9±0.4) mmol/L in the total 1 064 subjects. Among them, 126 subjects developed diabetes mellitus (DM) and 144 subjects developed impaired glucose regulation (IGR) during the follow-up visits. The proportions of IGR and diabetes increased with the FPG levels (P<0.05). The risk for developing IGR was significantly higher in subjects with FPG≥5.3 mmol/L than in those with FPG <5.3 mmol/L (RR=3.08, 95%CI 2.02-4.81, P<0.01). The risk for incident DM was markedly increased in subjects with FPG ≥ 5.6 mmol/L than in those with FPG <5.6 mmol/L (RR=6.73, 95%CI 3.90-11.52, P<0.01); (2)The risk for CVD was eight folds higher in subjects with FPG ≥5.3 mmol/L than in subjects with FPG <5.3 mmol/L (RR=8.42, 95%CI 5.11-13.82, P<0.05); (3)Survival analysis showed that the risk of death was 1.47 times higher in subjects with FPG ≥5.3 mmol/L than in subjects with FPG <5.3 mmol/L after years of followed-up (RR=1.47, 95%CI 1.09-1.98, P=0.0127). CONCLUSION The risks for IGR, CVD and mortality are higher in the elderly with FPG≥5.3 mmol/L, which highlights the importance for the disease prevention in elder people with FPG 5.3 mmol/L or more.

Abstract
Intestinal crypt progenitor/stem (ICPS) cell apoptosis and vascular endothelial cell apoptosis are responsible for the initiation and development of ionizing radiation (IR)-evoked gastrointestinal syndrome. The signaling mechanisms underlying IR-induced ICPS cell apoptosis remain largely unclear. Our findings provide evidence that β-arrestin-2 (βarr2)-mediated ICPS cell apoptosis is crucial for IR-stimulated intestinal injury. βArr2-deficient mice exhibited decreased ICPS cell and intestinal Lgr5+ (leucine-rich repeat-containing G-protein-coupled receptor 5-positive) stem cell apoptosis, promoted crypt proliferation and reproduction, and protracted survival following lethal doses of radiation. Radioprotection in the ICPS cells isolated from βarr2-deficient mice depended on prolonged nuclear factor-κB (NF-κB) activation via direct interaction of βarr2 with IκBα and subsequent inhibition of p53-upregulated modulator of apoptosis (PUMA)-mediated mitochondrial dysfunction. Unexpectedly, βarr2 deficiency had little effect on IR-induced intestinal vascular endothelial cell apoptosis in mice. Consistently, βarr2 knockdown also provided significant radioresistance by manipulating NF-κB/PUMA signaling in Lgr5+ cells in vitro. Collectively, these observations show that targeting the βarr2/NF-κB/PUMA novel pathway is a potential radiomitigator for limiting the damaging effect of radiotherapy on the gastrointestinal system. Significance statement: acute injury to the intestinal mucosa is a major dose-limiting complication of abdominal radiotherapy. The issue of whether the critical factor for the initiation of radiation-induced intestinal injury is intestinal stem cell apoptosis or endothelial cell apoptosis remains unresolved. βArrs have recently been found to be multifunctional adaptor of apoptosis. Here, we found that β-arrestin-2 (βarr2) deficiency was associated with decreased radiation-induced ICPS cell apoptosis, which prolonged survival in abdominally irradiated mice. Moreover, βarr2 deficiency-mediated intestinal progenitor/stem cell radioprotection relied on protracted NF-κB activation and subsequent suppression of PUMA induction. Our results suggest that ICPS cell apoptosis is the factor involved in the initiation and development of radiation-induced gastrointestinal syndrome. βArr2 is a potential target for lessening radiation-induced ICPS cell apoptosis.

Abstract
OBJECTIVE To explore the effects of job content on psychological stress in young recruits. METHODS In October 2014, 625 young recruits enrolled in one troop of Xinjiang Military Command in 2014 were chosen as subjects by multi-stage stratified random sampling. The Chinese version of the job content questionnaire (JCQ)and the psychological stress self evaluation test (PEST)were used to investigate the subjects. The subjects were divided into two groups with scores higher and lower than the mean score of three subscales (job requirement, degree of autonomy, and social support)of JCQ to explore the effects of job content on psychological stress in young recruits. The correlation of psychological stress with three subscales of job content was evaluated using the Pearson' s correlation analysis. Binary logistic regression analysis was used to analyze the influencing factors for psychological stress. RESULTS The PEST score of young recruits was 49.98±9.98. Forty-five (7.68%)out of them had scores of ≥70 points and were diagnosed with high levels of psychological stress. When the subjects were grouped based on socio-demographic characteristics, a high level of psychological stress was significantly more frequent in subjects less than 20 years of age than in those not less than 20 years of age, in smoking subjects than in non-smoking subjects, and in urban residents than in rural residents (10.42% vs 5.03%, P<0.05; 10.14% vs 5.33%, P<0.05; 10.85% vs 5.88% , P <0.05). There were no significant differences in educational level or identity before recruitment between subjects with different levels of psychological stress (P>0.05). In various job content domains that had impacts on psychological stress, subjects with a low score of social support had significantly higher PEST scores than those with a high score of social support (50.96±10.35 vs 48.49±9.22, P<0.01). The PEST score was negatively correlated with the degree of autonomy and social support (r=-0.103, P<0.05; r=-0.239, P<0.05). The results of logistic regression analysis showed that job requirement and social support were influencing factors for psychological stress (OR=0.718, 95% CI= 0.718 (0.607~0.851), P<0.05; OR=1.185, 95% CI=1.185 (1.087~1.292), P<0.05). CONCLUSION Psychological stress of young recruits in army is not optimistic. Psychological stress is weakly negatively correlated with social support. The low scores on job requirement subscale and social support subscale may be potential protective factor and risk factor for psychological stress, respectively.

Abstract
BACKGROUND Interleukin-2 (IL-2) -330 T/G promoter polymorphism is involved in the acute rejection (AR) risk of kidney transplantation. However, results from published studies on the association between recipient IL-2-330 T/G polymorphism and AR risk are conflicting and inconclusive. METHODS We searched Medline, Embase, Web of Science, and Cochrane Central Register from their inceptions through January 2015 for relevant studies. Data concerning publication information, population characteristics, and transplant information were extracted. Odds ratios (ORs) were calculated for the association between IL-2-330 T/G polymorphism and AR risk. RESULTS This meta-analysis included 8 case-control studies with 1,405 cases of renal transplant recipients. The pooled estimate showed that IL-2-330 T/G polymorphism was not associated with AR risk: TT vs TG+GG: OR(fixed,) 0.93; 95% confidence interval [CI], 0.72-1.21; P = .60; GG vs TG+TT: OR(fixed), 1.15; 95% CI, 0.76-1.72; P = .51; TG vs TT+GG: OR(fixed), 1.01; 95% CI, 0.78-1.31; P = .91; T vs G: OR(fixed), 0.93; 95% CI, 0.77-1.13; P = .48. None of subgroup analyses yielded significant results in the association between IL-2-330 T/G polymorphism and AR risk. Meta-regression confirmed that there was no significant correlation between the preselected trial characteristics and our study results. CONCLUSIONS This meta-analysis suggests that IL-2-330 T/G polymorphism may not be associated with AR risk in renal transplant recipients.

Abstract
OBJECTIVE To evaluate the efficiency of the tibial coronal alignment after total knee arthroplasty with the extramedullary cutting system guided by the tibial tubercle and anterior tibial tendon, and to discuss the potential risk factors for the postoperative malalignment. METHODS A retrospective study of 212 primary unilateral TKA surgeries (in 188 patients) in our hospital between June to December in 2014 had been analysed. All the cases were performed by one surgical group. An extramedullary tibial cutting guide system had been used, with a landmark of one third inner-medial tibial tubercle as a proximal anatomy reference, and anterior tibial tendon as a distal marker. The mechanical axis of lower extremity in full-length X-ray was measured before surgery, and the tibial prosthetic coronal alignment was checked two weeks postoperation, evaluating the accuracy of this extramedullary cutting system guided by our method. RESULTS Since good alignment was defined as an angle within 3 degrees of the perpendicular to the mechanical axis, the tibial component positions were acceptable in 191 knees (90.1%), five knees were in valgus postoperative, and sixteen knees were in varus. There were seventeen(8.7%) in 179 knees with a preoperative varus presented malalignment after surgery, and four in 12 preoperative valgus kneess howed malalignment also, no statistical difference was found by Chi-square test(χ(2)=2.778,P=0.096), which cannot define the relationship between the varus or valgus deformity preoperation and the malalignmentposition in tibial prosthesis after surgery. Twenty-two knees suffered a severe preoperative deformity as a varus or valgus angle larger than 20 degrees with absolute value of mechanical axis before surgery and tibial prosthetic coronal alignment were 21.95 °(20.00°,26.90°)and 1.85°(0.10°, 7.10°), showed a significant difference (Z=2.11,P=0.035) compared with the data [10.65°(0.50°,19.80°)in preoperative mechanical axis and 1.10°(0.00°,4.60°)in the tibial prosthetic coronal alignment]of 190 knees who presented a mild deformity before surgery(less than 20 degrees), the result indicated the severe preoperative deformity might be a potential mal-alignment risk factor within this cutting system in TKA surgery. CONCLUSION The tibial coronal alignment after total knee arthroplasty could achieve good results with extramedullary cutting guide, by using one third inner-medial tibial tubercle and anterior tibial tendon as a proximal and distal anatomy marker. Postoperative varus might occur in this system, and tibial prosthetic malalignment appeared more often in the patients who suffered a severe deformity before surgery.

Abstract
BACKGROUND Multiple case definitions are in use to identify chronic fatigue syndrome (CFS). Even when using the same definition, methods used to apply definitional criteria may affect results. The Centers for Disease Control and Prevention (CDC) conducted two population-based studies estimating CFS prevalence using the 1994 case definition; one relied on direct questions for criteria of fatigue, functional impairment and symptoms (1997 Wichita; Method 1), and the other used subscale score thresholds of standardized questionnaires for criteria (2004 Georgia; Method 2). Compared to previous reports the 2004 CFS prevalence estimate was higher, raising questions about whether changes in the method of operationalizing affected this and illness characteristics. METHODS The follow-up of the Georgia cohort allowed direct comparison of both methods of applying the 1994 case definition. Of 1961 participants (53 % of eligible) who completed the detailed telephone interview, 919 (47 %) were eligible for and 751 (81 %) underwent clinical evaluation including medical/psychiatric evaluations. Data from the 499 individuals with complete data and without exclusionary conditions was available for this analysis. RESULTS A total of 86 participants were classified as CFS by one or both methods; 44 cases identified by both methods, 15 only identified by Method 1, and 27 only identified by Method 2 (Kappa 0.63; 95 % confidence interval [CI]: 0.53, 0.73 and concordance 91.59 %). The CFS group identified by both methods were more fatigued, had worse functioning, and more symptoms than those identified by only one method. Moderate to severe depression was noted in only one individual who was classified as CFS by both methods. When comparing the CFS groups identified by only one method, those only identified by Method 2 were either similar to or more severely affected in fatigue, function, and symptoms than those only identified by Method 1. CONCLUSIONS The two methods demonstrated substantial concordance. While Method 2 classified more participants as CFS, there was no indication that they were less severely ill or more depressed. The classification differences do not fully explain the prevalence increase noted in the 2004 Georgia study. Use of standardized instruments for the major CFS domains provides advantages for disease stratification and comparing CFS patients to other illnesses.

Abstract
Interleukin-6 (IL-6) is a multifunctional cytokine that is involved in tumor cell proliferation, apoptosis, and differentiation. The purpose of this study was to evaluate the impact of the single nucleotide polymorphism (SNP) -174G/C in IL-6 on the prognosis and pain tolerance of non-small cell lung cancer (NSCLC) patients. DNA was extracted from the peripheral blood of 434 patients with NSCLC, which was diagnosed by cytology or histology. Polymerase chain reaction-restriction fragment length polymorphism was used to detect the IL-6 -174G/C genotypes and their correlation with survival was analyzed. The IL-6 -174G/C genotypes were high IL-6 production type (G carriers - GG or GC genotypes) and low IL-6 production type (CC genotype). The correlation between the IL-6 SNP and pain level/analgesic use was also analyzed. Survival analysis showed that patients carrying the G allele (CG/GG) had a shorter survival time than patients with the CC genotype. The -174G/C SNP is in the promoter region of the IL-6 gene and may be associated with changes in gene transcription and serum cytokine levels. Presence of the IL-6 -174G/C SNP is significantly correlated with morphine equivalent daily dose. Patients with the CC genotype needed a higher opioid dose than patients with the GG or GC genotypes. In conclusion, we found that the IL-6 -174G/C SNP is closely related to survival, analgesic use and pain tolerance in NSCLC patients. However, it is necessary to further validate the results with a larger patient cohort and elucidate the mechanisms of this SNP.

Abstract
Non-fibrillar soluble oligomeric forms of amyloid-β peptide (oAβ) and tau proteins are likely to play a major role in Alzheimer's disease (AD). The prevailing hypothesis on the disease etiopathogenesis is that oAβ initiates tau pathology that slowly spreads throughout the medial temporal cortex and neocortices independently of Aβ, eventually leading to memory loss. Here we show that a brief exposure to extracellular recombinant human tau oligomers (oTau), but not monomers, produces an impairment of long-term potentiation (LTP) and memory, independent of the presence of high oAβ levels. The impairment is immediate as it raises as soon as 20 min after exposure to the oligomers. These effects are reproduced either by oTau extracted from AD human specimens, or naturally produced in mice overexpressing human tau. Finally, we found that oTau could also act in combination with oAβ to produce these effects, as sub-toxic doses of the two peptides combined lead to LTP and memory impairment. These findings provide a novel view of the effects of tau and Aβ on memory loss, offering new therapeutic opportunities in the therapy of AD and other neurodegenerative diseases associated with Aβ and tau pathology.

Abstract
OBJECTIVE To discuss the curative effects of laparoscopy partial nephrectomy (LPN) combined with laparoscopy cryoablation (LCA) in treating renal cancer. PATIENTS AND METHODS A total of 58 patients that were diagnosed with phase III-IV renal cancer in the Hospital from February 2013 to October 2014 were enrolled in this study. After obtaining the approval of Ethics Committee of the Hospital as well as the informed consent of the patients and their relatives, the patients were randomly divide into two groups: control group consisted of 24 patients, who were treated with LPN + chemo radiotherapy and the observation group consisted of 34 patients, who were treated with LPN in combination of LCA + chemo radiotherapy. RESULTS The rate of successful operation was significantly higher in the observation group than in control group and the prevalence of per procedural complications in observation group was significantly lower than that of control group, and these differences had statistical significance (p < 0.05). Glomerular filtration rate (eGFR) after operation and 6-month follow-up in observation group was significantly higher than that in control group, and the level of serum creatinine (sCr) was significantly lower compared to the control group and the differences had statistical significance (p < 0.05). Follow-up survival rate of patients in the observation group was significantly higher than that of control group, recurrence rate and recurrence time of patients in the observation group was significantly lower than those of control group and the difference had statistical significance (p < 0.05). CONCLUSIONS LPN combined LCA therapy was quite effective in treating with middle and advanced renal cancer. Compared with pure LPN therapy, LPN combined LCA therapy could significantly improve the surgical effects, retain the functions of the renal unit and improve the patients' prognosis.

Abstract
Long non-coding RNAs (lncRNAs), which are extensively transcribed from the genome, have been proposed to be key regulators of diverse biological processes. However, little is known about the role of lncRNAs in regulating spermatogenesis in human males. Here, using microarray technology, we show altered expression of lncRNAs in the testes of infertile men with maturation arrest (MA) or hypospermatogenesis (Hypo), with 757 and 2370 differentially down-regulated and 475 and 163 up-regulated lncRNAs in MA and Hypo, respectively. These findings were confirmed by quantitative real-time PCR (qRT-PCR) assays on select lncRNAs, including HOTTIP, imsrna320, imsrna292 and NLC1-C (narcolepsy candidate-region 1 genes). Interestingly, NLC1-C, also known as long intergenic non-protein-coding RNA162 (LINC00162), was down-regulated in the cytoplasm and accumulated in the nucleus of spermatogonia and primary spermatocytes in the testes of infertile men with mixed patterns of MA compared with normal control. The accumulation of NLC1-C in the nucleus repressed miR-320a and miR-383 transcript and promoted testicular embryonal carcinoma cell proliferation by binding to Nucleolin. Here, we define a novel mechanism by which lncRNAs modulate miRNA expression at the transcriptional level by binding to RNA-binding proteins to regulate human spermatogenesis.

Abstract
An interesting aspect of Newcastle disease virus (NDV) is the ability to selectively replicate in tumor cells. Recently, using reverse genetics technology to enhance the oncolytic properties and therapeutic potential of NDV for tumor therapy has become popular in immunocompetent carcinoma tumor models. Expressing foreign genes by recombinant NDV (rNDV-FG) has been shown to be more effective in cancer therapy in preclinical studies. This paper provides an overview of the current studies on the cytotoxic and anti-cancer effects of rNDV-FG via direct oncolysis and immune stimulation. Safety of rNDV-FG as a therapeutic agent for cancer immunotherapy and virotherapy is also discussed.

Abstract
The aim of this study was to examine the relationship between genetic polymorphisms in DNA ligase 1 (LIG1) and non-small cell lung cancer (NSCLC) susceptibility and radiosensitivity in a Chinese population. This was a case-control study that included 352 NSCLC patients and 448 healthy controls. Polymerase chain reaction-restriction fragment length polymorphism analysis was conducted to detect HaeIII polymorphisms in exon 6 of the LIG1 gene in this popula-tion. This information was used to observe the effects of radiation in pa-tients with different genotypes in order to determine the genotypes as-sociated with radiosensitivity. The CC genotype and C allele frequency were significantly higher in the NSCLC group than in the control group (P = 0.012 and P = 0.023, respectively). The relative risk of experienc-ing NSCLC was 2.55 [95% confidence interval (CI), 1.12-3.98] for CC homozygous patients and 0.87 (95%CI, 0.46-1.88) for AA homozygous patients. Analysis of LIG1 genetic polymorphisms and radiosensitiv-ity of NSCLC patients showed that AA homozygous patients were sig-nificantly more radiosensitive than the control group (AA vs AC, P = 0.014; AA vs CC, P < 0.001; AC vs CC, P = 0.023). Therefore, the LIG1 CC genotype was associated with susceptibility to NSCLC, and the AA genotype demonstrated increased radiosensitivity compared to the AC and CC genotypes.

Abstract
Psychological disturbances, including anxiety and depression, are common during human pregnancy. Our objective was to determine whether these maternal disturbances influence cardiovascular responses of the offspring. The psychological status of 231 pregnant women was determined. Offspring (216) of these women were subsequently exposed to a video challenge stress when aged 7-9 years. Heart rate (HR) and blood pressure (BP) of the children were determined at rest, in response to video stress and during subsequent recovery. Children's resting and stress-induced increases in HR (bpm), systolic (SBP, mm Hg) and diastolic (DBP, mm Hg) BP were all greater in children whose mothers reported anxiety during pregnancy. Values (mean±s.d.) for resting HR, SBP and DBP were 75.15±5.87, 95.37±2.72 and 66.39±4.74 for children whose mothers reported no anxiety and an average of 81.62±6.71, 97.26±2.90 and 68.86±2.82 for children whose mothers reported anxiety at any level. Respective values for stress-induced increments in HR, SBP and DBP were 14.83.±2.14, 16.41±1.97 and 12.72±2.69 for children whose mothers reported no anxiety and 17.95±3.46, 18.74±2.46 and 14.86±2.02 for children whose mothers reported any level of anxiety. Effects of maternal depression were less consistent. The effects of maternal anxiety remained in multivariate analyses, which also included children's birth weight. The results indicate a long-term influence of maternal psychological status during pregnancy on the cardiovascular responses to stress among offspring. These effects may contribute to prenatal influences on subsequent health of the offspring.

Abstract
OBJECTIVE The aim of this study was to evaluate multisequence 3.0-T MRI in the detection of severe traumatic brain injury (sTBI) and in predicting the outcome. METHODS 32 patients with sTBI were prospectively enrolled, and multisequence 3.0-T MRI was performed 4-8 weeks post injury. Quantitative data were recorded on each sequence. The ability to display the parenchymal lesions was compared with that of 64-slice spiral CT. The clinical and radiological results were correlated with the Glasgow Outcome Scale Extended scores 6 months after injury. RESULTS 3.0-T MRI could display more lesions than CT, especially when the lesion was deeply located. The lesion volumes and diffuse axonal injury (DAI) scores were different between good and poor outcome groups on fluid attenuated inversion recovery (p < 0.05). The apparent diffusion coefficient (ADC) values of the splenium of the corpus callosum and brain stem were also different (p < 0.05). Patients with unfavourable outcome showed a significantly higher volume of haemorrhage on susceptibility-weighted imaging than those with favourable outcomes and had haemorrhages generally located more deeply. Logistic regression analysis revealed that the location of haemorrhage and the ADC values of the splenium of the corpus callosum were independent risk factors for poor outcome, with an overall predictive accuracy of 91.4%. CONCLUSION The joint use of conventional and advanced sequences of 3.0-T MRI can comprehensively detect the pathological changes occurring after sTBI. Haemorrhagic and non-haemorrhagic DAIs in deep structures strongly suggest poor outcome. ADVANCES IN KNOWLEDGE This article improves the understanding of advanced MRI sequences in the detection of patients with sTBI and prediction of prognosis.

Abstract
The results in this study show the prevalence of Yersinia enterocolitica varies in different animal species and regions of China. The highest prevalence is among pigs (12.91%), followed by dogs (9.80%), Ochotona curzoniae (plateau pica) (6.76%), chickens (4.50%), rodents (3.40%), cattle (2.78%) and sheep (0.89%). Pathogenic isolates comprised the majority of the Y. enterocolitica recovered from pigs (73.50%) and dogs (59.44%); whereas the nonpathogenic Y. enterocolitica made up most of poultry and wildlife recovered strains. A correlation analysis comparing the prevalence and geographic factors showed the isolation rate of Y. enterocolitica in pigs and dogs was negatively correlated with elevation (r=-0.50, P<0.05) and annual average air temperature (r=-0.43, P<0.05), but there was positive correlation with annual precipitation (r=0.43, P<0.05); conversely, the isolation rate from wildlife is positively correlated with elevation (r=0.3, P<0.05) contrary to the result seen in livestock. Twelve novel biotype 2 pathogenic Y. enterocolitica carried ail and ystB virulence genes, and one biotype 1A nonpathogenic strain positive with ail, ystB and ystA genes were isolated from Microtus fuscus (Qinghai vole) on plague foci of the Qinghai-Xizang plateau. The PFGE pattern K6GN11C30021 was predominant in pigs (44.25%) and patients (41.18%); K6GN11C30068 was predominant in dogs (40.16%). Animal isolates from the same region shared the same pattern (K6GN11C30021 and K6GN11C30012), indicating they may be from the same clone and arose through cross infection. Moreover, the identical PFGE pattern among local animals and diarrhea patients suggested that the animals may be the source of infections in these areas.

Abstract
BACKGROUND The spatial spread of H5N1 avian influenza, significant ongoing mutations, and long-term persistence of the virus in some geographic regions has had an enormous impact on the poultry industry and presents a serious threat to human health. METHODS We applied phylogenetic analysis, geospatial techniques, and time series models to investigate the spatiotemporal pattern of H5N1 outbreaks in China and the effect of vaccination on virus evolution. RESULTS Results showed obvious spatial and temporal clusters of H5N1 outbreaks on different scales, which may have been associated with poultry and wild-bird transmission modes of H5N1 viruses. Lead-lag relationships were found among poultry and wild-bird outbreaks and human cases. Human cases were preceded by poultry outbreaks, and wild-bird outbreaks were led by human cases. Each clade has gained its own unique spatiotemporal and genetic dominance. Genetic diversity of the H5N1 virus decreased significantly between 1996 and 2011; presumably under strong selective pressure of vaccination. Mean evolutionary rates of H5N1 virus increased after vaccination was adopted in China. A clear signature of positively selected sites in the clade 2.3.2 virus was discovered and this may have resulted in the emergence of clade 2.3.2.1. CONCLUSIONS Our study revealed two different transmission modes of H5N1 viruses in China, and indicated a significant role of poultry in virus dissemination. Furthermore, selective pressure posed by vaccination was found in virus evolution in the country.

Abstract
PURPOSE OF INVESTIGATION The present study aimed to investigate the effect of Piwil2 on proliferation and invasion of cervical cancer cells. MATERIALS AND METHODS Thirty-two HPV-positive or negative cervical cancer tissues and corresponding normal adjacent cervical tissues were obtained from General Hospital of Lanzhou Military Region. Piwil2 expression in these tissue samples, as well as two cervical cell lines were evaluated by quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemical. A specific short hairpin RNA (shRNA) was used to knockdown the Piwil2 gene in SiHa cells. CCK-8 assay and flow cytometry (FCM) was used to evaluate cell proliferation. Cell invasion was detected by transwell chambers assays. Immunoblotting was used to assess the effect on relevant proteins. RESULT In the early stage (I A1-I B1) of curvival, 84.4% (27/32) tumor tissues have a more predominant expression of Piwil2 than the normal adjacent samples. Piwil2 overexpression was correlated with HPV16 infection (p < 0.05). Knockdown of Piwil2 gene in SiHa cells inhibited cell growth and invasion, and downregulated matrix metalloproteinase-9 (MMP-9) compared to scrambled shRNA transfected cells. Further analysis revealed that downregulation of Piwil2 gene induced inhibition of the MAPK signaling pathway activity. CONCLUSION Piwil2, which stimulated by HPV16 infection, plays an important role in regulating proliferation and invasion of cervical cells by regulating MMP-9 expression via alternation of the MAPK signaling pathway.

Abstract
As the interface between the Sun's photosphere and corona, the chromosphere and transition region play a key role in the formation and acceleration of the solar wind. Observations from the Interface Region Imaging Spectrograph reveal the prevalence of intermittent small-scale jets with speeds of 80 to 250 kilometers per second from the narrow bright network lanes of this interface region. These jets have lifetimes of 20 to 80 seconds and widths of ≤300 kilometers. They originate from small-scale bright regions, often preceded by footpoint brightenings and accompanied by transverse waves with amplitudes of ~20 kilometers per second. Many jets reach temperatures of at least ~10(5) kelvin and constitute an important element of the transition region structures. They are likely an intermittent but persistent source of mass and energy for the solar wind.

Abstract
The physical processes causing energy exchange between the Sun's hot corona and its cool lower atmosphere remain poorly understood. The chromosphere and transition region (TR) form an interface region between the surface and the corona that is highly sensitive to the coronal heating mechanism. High-resolution observations with the Interface Region Imaging Spectrograph (IRIS) reveal rapid variability (~20 to 60 seconds) of intensity and velocity on small spatial scales (≲500 kilometers) at the footpoints of hot and dynamic coronal loops. The observations are consistent with numerical simulations of heating by beams of nonthermal electrons, which are generated in small impulsive (≲30 seconds) heating events called "coronal nanoflares." The accelerated electrons deposit a sizable fraction of their energy (≲10(25) erg) in the chromosphere and TR. Our analysis provides tight constraints on the properties of such electron beams and new diagnostics for their presence in the nonflaring corona.

Abstract
The heating of the outer solar atmospheric layers, i.e., the transition region and corona, to high temperatures is a long-standing problem in solar (and stellar) physics. Solutions have been hampered by an incomplete understanding of the magnetically controlled structure of these regions. The high spatial and temporal resolution observations with the Interface Region Imaging Spectrograph (IRIS) at the solar limb reveal a plethora of short, low-lying loops or loop segments at transition-region temperatures that vary rapidly, on the time scales of minutes. We argue that the existence of these loops solves a long-standing observational mystery. At the same time, based on comparison with numerical models, this detection sheds light on a critical piece of the coronal heating puzzle.

Abstract
The solar chromosphere and transition region (TR) form an interface between the Sun's surface and its hot outer atmosphere. There, most of the nonthermal energy that powers the solar atmosphere is transformed into heat, although the detailed mechanism remains elusive. High-resolution (0.33-arc second) observations with NASA's Interface Region Imaging Spectrograph (IRIS) reveal a chromosphere and TR that are replete with twist or torsional motions on sub-arc second scales, occurring in active regions, quiet Sun regions, and coronal holes alike. We coordinated observations with the Swedish 1-meter Solar Telescope (SST) to quantify these twisting motions and their association with rapid heating to at least TR temperatures. This view of the interface region provides insight into what heats the low solar atmosphere.
