Abstract
Objective: To investigate the respiratory central hypoxia response and its related factors in Han and Uygur patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: One hundred and sixty six OSAHS patients were selected from Jan. 2016 to Dec. 2016 in Department of Respiratory and Critical Care Medicine, Kelamayi Central Hospital, including 69 cases of Han nationality and 97 cases of Uygur nationality. Seventy-three healthy subjects of Uygur nationality were enrolled as the control group. All of them under went sleep monitoring, nocturnal oxygen saturation (SaO(2)), pulmonary function and respiratory central hypoxia response. Results: The 3 groups were matched for age, gender, body mass index(BMI) and apnea-hypopnea index(AHI). The Uygur patients had a higher oxygen desaturation index (ODI4) [(30±22) per hour vs (18±17) per hour ] than Han patients of the same age and BMI. Compared to Han patients, Uygur patients had weaker hypoxic responsiveness [(-0.41±0.23) L·min(-1)·%(-1) vs (-0.36±0.22) L·min(-1)·%(-1,) P<0.05], and the difference still existed after adjusting for AHI [(-0.31±0.21) L·min(-1)·%(-1) vs (-0.41±0.22) L·min(-1)·%(-1,) P<0.05] in mild OSAHS, but this difference was not significant in severe OSAHS. Conclusions: The central hypoxic response in Uygur OSAHS patients was lower than that in Han OSAHS patients and normal controls.

Abstract
PURPOSE Lymph node metastasis (LNM) is a vital prognosis factor in patients with papillary thyroid microcarcinoma (PTMC). The study tried to identify clinicopathological factors for LNM of PTMC. METHODS The clinicopathological data of 1031 patients with PTMC were extracted and analyzed. Univariate and multivariate analyses were used to identify risk factors associated with cervical lymph node metastasis. ROC analysis was used to determine the ideal critical points of the sum of the maximum diameter of multifocal in a unilateral lobe. RESULTS The probability of LNM, central lymph node metastasis (CLNM) and lateral lymph node metastasis(LLNM)of PTMC patients were 35.6, 33.7 and 5.6%, respectively. In addition, 1.9% PTMC had LLNM only. Male, age ≤ 40 years, tumor largest diameter ≥ 5 mm, multifocal, non-uniform echoic distribution, the sum of the maximum diameter of multifocal in a unilateral lobe ≥ 8.5 mm, tumors in the lower pole location were prone to CLNM. Ultrasound mix-echo, the sum of the maximum diameter of the multifocal ≥ 10.75 mm, tumors in the upper pole location were extremely prone to LLNM. T3 were prone to LLNM or skip LLNM. CONCLUSIONS According to the clinicopathological characteristics of PTMC, the cervical lymph nodes should be correctly evaluated to guide the surgical treatment.

Abstract
Criteria for diagnosis of Alzheimer's disease (AD) is not available in China. The international criteria is not a proper choice due to issues such as translation and lead to low diagnostic rate and high rate of missed diagnosis. The research group of Alzheimer's Disease Chinese (ADC) reviewed knowledge and techniques in neuropsychology, neuroimaging, molecular biology, and clinical neurology, and systematically studied the detection techniques such as memory, language, visuospatial, executive function, and medial temporal lobe visual scores on MRI, and their optimal threshold and diagnostic value for the diagnosis of AD. Through a systematic review and consensus meeting, a diagnostic framework for screening AD in the Chinese population was established. Among these methods, an operational standard for clinical pathology models increased the diagnostic sensitivity by 15%. The sensitivity and specificity of screening memory impairment increased by 18.1% and 11.6%, respectively. The sensitivity of screening medial temporal lobe atrophy increased by 24.5% and missed diagnosis was decreased by 34.5%. An operational standard for clinical biology models, incorporating the latest molecular imaging and molecular biology techniques, has enabled the early diagnosis of AD in China. The framework combines a principled diagnostic guideline with an operational screening protocol, which is applicable to all clinical settings and of great significance for the early detection, early diagnosis and early treatment of AD.

Abstract
OCT4, a marker of embryonic stem cells, is also a key transcription factor that plays a regulatory role in the self-renewal, proliferation and differentiation of stem cells. Previous studies showed that DNA methylation is involved in the regulation of OCT4 expression during the development and differentiation of embryonic stem cells. However, DNA methylation in the promoter region of OCT4 has not yet been discussed in human recurrent glioma. In this study, we assessed the specimens from 24 cases of recurrent glioma for OCT4 expression and methylation status, and commenced analyzing the correlation between the two by treating glioma cells with a demethylating agent in vitro. The results demonstrated that for the same cases, the expression of OCT4 in specimens of recurrent glioma was significant higher than that in primary glioma (P<0.05). DNA methylation levels in recurrent glioma decreased obviously compared with that in primary glioma (t=9.800, P=0.008). In vitro study indicated, following demethylation treatment, glioma cells had an increased OCT4 expression. These results suggest that DNA hypomethylation may be a key mechanism underlying the up-regulation of OCT4 in the recurrence of glioma, which facilitates the understanding of the role of stem cells and the exploration of novel strategies for the treatment of recurrent glioma.

Abstract
Mucormycosis is an uncommonly encountered fungal infection in solid-organ transplantation, occurring most often gastrointestinally. The most common and fatal infectious disease is cytomegalovirus (CMV) pneumonia, which may result in acute respiratory distress syndrome (ARDS), with rapid onset. Early diagnosis, active treatment, and rational reduction of immunosuppressants are crucial for successful kidney transplantation. We performed successful treatment for both mucormycosis and CMV pneumonia and adjusted the tacrolimus dose accordingly. The case we describe was that of a 47-year-old woman with history of renal transplantation 1 month earlier. She presented with chest pain and gastrointestinal bleeding and was diagnosed with gastric mucormycosis and a secondary episode of hospital-acquired pneumonia. Preemptive therapy, which included liposomal amphotericin B and posaconazole, was adminstered when voriconazole proved to be unhelpful and before histologic reports of gastric mucormycosis. Moreover, CMV re-activation was confirmed by CMV antibody detection, and we administered gancyclovir and thymosin α1 but reduced the strength of the immunosuppressive drugs. Fourteen days after the aforementioned therapy, the patient began to recover and she was discharged on day 81 postoperatively. We conclude that preemptive treatment is critical for severe infection in renal transplant recipients, especially with the rarely seen gastric mucormycosis and with ARDS. In addition, immunoregulated agents, such as asthymosin α1, are also of great value in renal transplant recipients in the setting of opportunistic pathogen infections.

Abstract
There are two production clusters co-existed in the Institute of High Energy Physics (IHEP). One is a High Throughput Computing (HTC) cluster with HTCondor as the workload manager, the other is a High Performance Computing (HPC) cluster with Slurm as the workload manager. The resources of the HTCondor cluster are funded by multiple experiments, and the resource utilization reached more than 90% by adopting a dynamic resource share mechanism. Nevertheless, there is a bottleneck if more resources are requested by multiple experiments at the same moment. On the other hand, parallel jobs running on the Slurm cluster reflect some specific attributes, such as high degree of parallelism, low quantity and long wall time. Such attributes make it easy to generate free resource slots which are suitable for jobs from the HTCondor cluster. As a result, if there is a mechanism to schedule jobs from the HTCon-dor cluster to the Slurm cluster transparently, it would improve the resource utilization of the Slurm cluster, and reduce job queue time for the HTCondor cluster. In this proceeding, we present three methods to migrate HTCondor jobs to the Slurm cluster, and concluded that HTCondor-C is more preferred. Furthermore, because design philosophy and application scenes are di↵erent between HTCondor and Slurm, some issues and possible solutions related with job scheduling are presented.

Abstract
Objective: To estimate the prevalence of HIV/HCV co-infection and explore the influence factors and their interaction on HIV/HCV co-infection of patient's access to methadone maintenance treatment (MMT). Methods: A face to face interviews were conducted among 750 patients at two MMT clinics in Guangxi Zhuang Autonomous Region. The questionnaires information included demographic characteristics, HIV and HCV infection status, history of drug abuse, urine test for morphine, high risk sex behaviors, needle sharing, dropped out etc. Methods of χ(2) test one-way, multivariate logistic regression and interactions were used to analyze the related factors of HIV/HCV co-infection. Results: The study subjects included 750 participants, 18.31% (127/691) of patients were co-infected with HIV and HCV. The HIV/HCV co-infection rate in patients who shared needles with others or dropped out of treatment was 35.84% (81/226) and 19.88% (64/322) respectively, which were higher than those who have never shared needles or dropped out (9.89%, 46/465 and 17.07%, 63/369). Logistic regression analysis results showed that after adjusted for confounding factors, patients who shared needles (OR=4.50, 95%CI: 2.72-7.43) and dropped out of treatment (OR=1.71, 95%CI: 1.04-2.80) were more likely to be infected with HIV/HCV. Interaction analysis showed that sharing needles and dropping out of treatment exist additive effect on co-infection of HIV and HCV (RERI=4.21, AP=0.44, SI=1.95). Conclusions: Needle sharing and dropping out of treatment are associated with HIV/HCV co-infection. Health education, psychological counseling and other measures should be taken to reduce needle sharing and dropping out of MMT.

Abstract
Objective: To investigate the risk factors for multiparous pelvic floor muscles injury during 6-8 weeks after delivery. Method: From June 2015 to April 2017, 1917 women (1 523 primigravidas and 294 multiparas) were accepted postpartum pelvic floor function screening during 6-8 weeks after delivery in Beijing Hospital.Pelvic examination and pelvic floor muscle strength testing were carried out in these women.All the data were analyzed with multivariate logistic regression method to explore the related factors for postpartum pelvic floor muscle injury. Result: The incidence of muscle strength grades less than third grade was 63.60 % (type Ⅰ muscle fiber) and 24.83 % (type Ⅱ muscle fiber). Multivariate analysis showed that time interval, between two deliveries, less than 3 years (OR=2.16, 95%CI 1.21-3.86), and maternal BMI<18.5 (OR=3.04, 95%CI 1.10-9.30) and BMI≥28 (OR=3.04, 95%CI 1.10-9.30) before pregnancy were risk factors for postpartum injury of type Ⅰ muscle fiber. Gestational age more than 40 weeks increased the risk of damaging type Ⅱ muscle fiber (OR=2.79, 95%CI 1.156-6.76). Compared with cesarean section, vaginal delivery significantly increased the risk of injury of type Ⅰ and Ⅱ pelvic floor muscle fibers (P<0.05). Conclusion: The incidence of multiparous pelvic floor muscle injury was high in early postpartum period.Several factors are related to the pelvic floor muscle injury.Pelvic floor rehabilitation in early postpartum and maternal education may be helpful to reduce the radio of injury.

Abstract
There are no standard diagnostic criteria for Alzheimer's disease (AD) in China. The copied international criteria has led to a high rate of missed diagnosis due to issues such as translation and cultural discrepancy. Under the principles of semantic equivalence, content equivalence and performance equivalence, the research group of Alzheimer's Disease Chinese (ADC) adopted several effective methods, such as two-way translation, content conversion, performance evaluation, etc. to systematically study the cognitive, behavioral, functional, and general assessment techniques in dementia screening and diagnosis, as well as their screening thresholds and diagnostic values. We also established a dementia screening and assessment framework in clinical practice through systematic reviews and group consensus. It has improved the early diagnosis rate of dementia in China, been accepted by home and abroad academic institutions, which is of great significance for early diagnosis and treatment of dementia.

Abstract
Objective: The number of children with polydactyly is increasing. In addition to genetic factors, an influence of maternal behavior or environmental effects during pregnancy is becoming increasingly apparent. However, epidemiological data on these effects are lacking. Methods: This hospital-based, case-control study enrolled 143 infants with polydactyly and 286 controls without genetic diseases to evaluate the association between active and passive maternal smoking during pregnancy and the likelihood of giving birth to a child with polydactyly. Results: Active and passive maternal smoking during pregnancy was associated with an increased risk of giving birth to a child with polydactyly (active smoking: OR=4.74, 95%CI: 1.43-15.65, P=0.011; passive smoking: OR=2.42, 95%CI: 1.32-4.44, P=0.004). After adjusting for confounders, smoking during pregnancy remained significant influence on polydactyly (active smoking: aOR=7.27, 95%CI: 1.72-30.72, P=0.007; passive smoking: aOR=2.41, 95%CI: 1.11-5.23, P=0.026). Conclusion: Active and passive maternal smoking during pregnancy appears to be a risk factor for polydactyly in newborns.

Abstract
Objective: A variety of interstitial cells in tumor microenvironment (TME) based on glioma stem cells(GSC) have the function to promote malignant progression of tumors, but whether these interstitial cells have already undergone malignant transformation and their related molecular characteristics are still poorly understood. Methods: Human SU3-RFP glioma stem cells (GSC) stably transfected with red fluorescent protein (RFP) and interstitial cells from enhanced green fluorescent protein (EGFP) transgenic nude mice were co-cultured in vitro. SU3-RFP cells were also inoculated in different tissues of EGFP-Balb/c nude mice. Immortal EGFP(+) cells were monocloned either from co-culture cells in vitro, or from their xenografts in vivo. These immortal EGFP(+) cells were confirmed to bear characteristics of tumor cell via chromosomal analysis and tumorigenicity assay. Related molecular phenotypes of these cells were further detected through RT-PCR, flow cytometry and immunochemistry(IHC) techniques. Results: (1) Two EGFP(+) cell lines were obtained in vitro, and 5 EGFP(+) cell lines were obtained in vivo tumorigenic experiments. Seven EGFP(+) cell lines all have characteristics of self-renewal, heteroploid of chromosomes and 100% tumorigenicity. (2) Cell surface marker analysis showed cell origin of these cell lines were macrophages (tMΦ1 and tMΦ2 ), dendritic cells (tDC1 and tDC2), fibroblasts (tFB), oligodendrocytes (tOG) and BMSC cells (tBMSC), respectively. (3)All of these seven cell lines co-expressed Sca-1 and c-myc, and have Sox-2 or Nanog expression also, which suggest that they may bear molecular characteristics of mesenchymal stem cells or pluripotent stem cells. Conclusions: (1) Tumor stromal cells in TME have undergone malignant transformation, which is related to the tissue remodeling of TME by GSCs, and not limit to the specific type of their parasitic tissues. (2) Tumor cells originated from GSC and tumor interstitial cells, respectively, are two major types of tumor cells with different origins in glioma parenchyma, can not be simply regarded as tumor heterogeneity, transformed interstitial cells of TME may have the potential to serve as new targets for target diagnosis and therapy.

Abstract
AIM To assess the capacity of a body shape index and body roundness index to identify people with diabetes mellitus and those with prediabetes, and to determine whether a body shape index and/or body roundness index is superior to the traditional overall adiposity index, BMI, in Han Chinese people in Northeast China. METHODS A total of 15 078 participants were enrolled from Jilin province in 2012 using a multi-stage stratified random cluster sampling method. Demographic data were collected, and anthropometric indices and biochemical indices were measured. Receiver-operating characteristic curves were used to compare the validity of each anthropometric index, and the area under the receiver-operating characteristic curve was calculated for each anthropometric index. RESULTS Body roundness index had the highest areas under the receiver-operating curve for prediabetes, diagnosed diabetes and undiagnosed diabetes in both men and women (all P<0.01). The optimum threshold values for body roundness index for prediabetes, undiagnosed diabetes and diagnosed diabetes, respectively, were 2.8, 3.7 and 3.3 in men, and 3.4, 3.8 and 3.6 in women. The cumulative proportions of prediabetes, undiagnosed diabetes and diagnosed diabetes identified by the optimum threshold values of body roundness index were 79.2%, 67.5% and 77.0% (82.3%, 62.5% and 75.3% in men; 74.6%, 74.9% and 78.3% in women), respectively. CONCLUSIONS BMI, a body shape index and body roundness index may identify the presence of diabetes. Among the three anthropometric indices, BMI had the weakest association with diabetes. Body roundness index is an alternative index for assessing diabetes in Han Chinese people in Northeast China.

Abstract
Objective: To investigate the clinical, radiological and pathological features of visceral parasitic migration of the liver. Methods: Seven cases of visceral parasitic migration of liver were identified at the Affiliated Drum Tower Hospital of Medical School of Nanjing University from January 2008 to July 2017. Clinical data, enhanced CT image and pathological features were analyzed, combining with literature review. Results: There were 5 male and 2 female patients. Five patients presented with abdominal pain or discomfort as the first symptom. Two patients were admitted to the hospital for physical examination with liver nodule. Blood eosinophils were mildly to moderately increased in 4 cases. Enhanced CT showed the liver irregular beaded nodules that showed no significant enhancement of arterial phase. Mild enhancement of round lesions (ring lesion) was seen in a few cases before surgery. By histopathology, the lesions showed central geographic necrosis, surrounded by epithelioid granuloma and inflammatory cell bands. A large number of eosinophils and scattered multinucleated giant cells were found, especially at the peripheral of the lesion. Charcot-Leyden crystals were present in all case and parasitic migrans was found in one case. Conclusions: Visceral parasitic migration of liver is a rare liver disease and is easily misdiagnosed as other benign or malignant liver tumors. Combining clinical data, enhanced CT images and pathological examination can improve the preoperative and postoperative diagnosis of the disease.

Abstract
OBJECTIVES We carried out a randomized multicentre study in China to investigate whether the clofazimine would improve the efficacy of the standardized regimen in patients with multidrug-resistant tuberculosis (MDR-TB). METHODS Patients with MDR-TB managed in 17 TB specialist hospitals in China between September 2009 and September 2011 were randomly assigned to the treatment groups at enrolment. In the intervention group, 100 mg clofazimine per day was added to the standardized regimen. The primary outcome was the proportion of patients with successful outcomes. RESULTS From the 156 patients that were screened, 74 were assigned to the control group and 66 to the clofazimine group. Of the 66 cases analysed for clinical outcome in the clofazimine group, 36 patients were cured, and seven completed treatment, yielding a favourable outcome rate of 65.1%. The proportion of patients with favourable outcomes receiving the control regimen was 47.3% (35/74), which was significantly lower than that in the clofazimine group (p 0.034, relative risk 0.661, 95% CI 0.243-0.949). CONCLUSIONS The addition of clofazimine to the standard regimen improved the treatment of MDR-TB.

Abstract
Paclitaxel is a successful anti-cancer drug that kills cancer cells in two-dimensional culture through perturbation of mitosis, but whether it causes tumour regression by anti-mitotic actions is controversial. Drug candidates that specifically target mitosis, including inhibitors of kinesin-5, AurkA, AurkB and Plk1, disappointed in the clinic. Current explanations for this discrepancy include pharmacokinetic differences and hypothetical interphase actions of paclitaxel. Here, we discuss post-mitotic micronucleation as a special activity of taxanes that might explain their higher activity in solid tumours. We review data showing that cells which exit mitosis in paclitaxel are highly micronucleated and suffer post-mitotic DNA damage, and that these effects are much stronger for paclitaxel than kinesin-5 inhibitors. We propose that post-mitotic micronucleation promotes inflammatory signalling via cGAS–STING and other pathways. In tumours, this signalling may recruit cytotoxic leucocytes, damage blood vessels and prime T-cell responses, leading to whole-tumour regression. We discuss experiments that are needed to test the micronucleation hypothesis, and its implications for novel anti-mitotic targets and enhancement of taxane-based therapies.

Abstract
Objective: To analyze the preoperative axial plane and the surgical outcomes of the Lenke type 1A patients with adolescent idiopathic scoliosis (AIS) whose coronal curve type was matched but thoracic kyphosis (TK) was different. Methods: This study retrospectively reviewed a series of Lenke type 1A female AIS patients who underwent corrective surgery in the Department of Spine Surgery of Nanjing Drum Tower Hospital from May to August 2017. After matched with the Cobb angle of the main thoracic curve, the apical vertebral, the vertebra number included in the curve, the lumber modifier in the Lenke classification and Risser sign, 12 pairs of AIS patients, whose coronal curve was matched but thoracic kyphosis was different, were included in this study. The patients were divided into normal TK group and thoracic hypokyphosis group. EOS whole-body images were taken preoperatively and reconstructed by three-dimensional reconstruction. The whole spine anteroposterior X-ray was taken at 3 weeks after surgery. The radiographic parameters were measured on the preoperative and postoperative two-dimensional X-ray images: coronal Cobb angle, TK, lumbar lordosis (LL), pelvic incidence (PI) and pelvic tilt (PT). The vertebra rotation was obtained on the EOS three-dimensional reconstructed image, and the average vertebral rotation of the major thoracic curve (MTR), the average vertebral rotation of the proximal thoracic curve (PTR) and the average vertebral rotation of the lumbar curve (LR) were calculated. The paired sample t test was used to compare the difference of preoperative and postoperative radiographic parameters between the groups. Results: A total of 24 patients (12 pairs) were included in this study with an average age of (13.7±2.9) years. The preoperative Cobb angle was similar in the two groups (53.8°±10.2° vs 51.0°±11.1°, t=0.27, P=0.81). The average preoperative TK of the normal TK groups was 28.2°±6.1°, while that of the thoracic hypokyphosis group was 11.2°±5.6°(t=7.68, P<0.01). The MTR in the normal TK group was significantly smaller than that in the thoracic hypokyphosis group (10.2° vs 12.7°, t=-3.74, P<0.01), and there was a significant correlation between TK and MTR (r=0.30, P=0.03). As for the lumbar curve rotation, the LR of the normal TK group was significantly smaller than that in the thoracic hypokyphosis group (t=-2.65, P=0.002), but the absolute value of the two groups was similar (t=-0.33, P=0.31). The lumbar Cobb angle correction rate was significantly greater in patients with thoracic and lumbar curve rotating in the same direction than that in the opposite direction (81.1% vs 61.9%, t=4.24, P=0.005). Conclusions: It indicated that when the coronal deformity is matched, the MTR of the patients with thoracic hypokyphosis is significantly larger than that in the patients with normal thoracic kyphosis. The direction of the thoracic and lumbar curve rotation is required to be well concerned in the preoperative surgical planning.

Abstract
Objective: The goal of this research was to understand the demographic distribution and related factors of non-marital and non-commercial heterosexual transmission (non-commercial transmission) for HIV/AIDS (human immunodeficiency virus/acquired immunodeficiency syndrome). Methods: Data related to HIV/AIDS infected by non-marital heterosexual transmission and whose present address was in Qian Dongnan, were collected from Information System on the HIV/AIDS Prevention and Control. Information included demographic characteristics, the members of non-marital sex partners, transmission path, detection source, CD4(+)T lymphocyte level, et al. cases belong to homosexual history, injective drug use or non-classified non-marital heterosexuality transmission were excluded, totally collect HIV/AIDS 919 cases. Multivariate logistic regressions were used to analyze potential factors associated with non-marital and non-commercial heterosexual transmission. In addition, in March and June 2017, using a convenience sampling, we conducted one-to-one interviews among 10 HIV/AIDS who were infected by non-marital heterosexuality and had non-marital and non-commercial heterosexual experience in Kaili Center for Disease Control and Prevention. The content of the interview included basic information, sexual orientation, the main place of making friends and sexual behavior, attitude to commercial heterosexuality and non-martial and non-commercial heterosexuality and so on. Results: Out of the 919 cases, 645 (70.2%) were male, the proportion of non-commercial transmission was 55.06% (506). The proportion of female HIV/AIDS with non-commercial transmission was 84.7% (232), which was higher than male (42.5%(274)) (χ(2)=138.35, P<0.001). The proportion of Han HIV/AIDS with non-commercial transmission was 61.5% (275), which was higher than other religion (52.2%(412)) (χ(2)=6.32, P=0.012). The proportion of HIV/AIDS with non-commercial transmission who had 0-5 non-marital sexual partners was 58.8% (498), which was higher than who had>5 non-marital sexual partners (11.1%(8)) (χ(2)=61.10, P<0.001). The proportion of HIV/AIDS with non-commercial transmission who lived mobile was 72.9% (94), which was higher than who lived fixedly (52.2%(412)) (χ(2)=19.34, P<0.001). Qualitative interviews results revealed that the age of the respondents were 22-69. Respondents whose ages are in 22-34 were more likely to use mobile phone (4/10) and respondents whose ages are in 35-69 were less likely to look partners through party and the context of working. Conclusion: The proportion of cases being infected by non-marital and non-commercial heterosexual transmission in Qian dongnan was higher than general national levels. The characteristics of sex, marriage status, migration, vocation, the members of non-marital sex partners were significant differed between commercial heterosexual transmission and non-marital and non-commercial heterosexual transmission.

Abstract
Objective: To study the role of ApoE gene polymorphism on efficacy of atorvastatin in lowering the lipid and its clinical significance. Methods: A total of 962 patients with hypercholesterolemia were selected between January 1 st and December 31 st 2014. The ApoE genepolymorphism in patients with hyperlipidemia was performed by using polymerase chain reaction with restriction fragment length polymorphism (PCR-RFLP) method in translational medicine center of Huaihe Hospital. Patients with ApoE genotype E3/3 and E3/4 were selected and treated with atorvastatin 10 mg/d for 4 weeks. Before and after treatment, triglycerides (TG) and total cholesterol (TC) was detected by enzyme colorimetry method. High-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were performed by Clearance method. Lipoprotein(a) (Lp(a)) was performed by turbidimetric inhibition immunoassay. ApoE gene expression was performed by real-time PCR. Results: In the 6 gene types, the frequencies of E3/4 and E3/3 were 30.6% (294 cases) and 59.1% (569 cases) respectively. After treatment with atorvastatin, the change percent of TC, LDL-C, HDL-C, TG, Lp(a) in E3/4 and E3/3 group were -(23.0±4.7)% vs -(12.0±3.1)% (P<0.001), -(33.0±4.8)% vs -(20.0±3.9)% (P<0.001), (18.0±3.8)% vs (6.0±2.6)% (P<0.001), -(23.0±3.9)% vs -(13.0±2.7)% (P<0.001), -(21.5±4.5)% vs -(20.9±4.0)% (P=0.054), respectively. ApoE gene expression in E3/3 and E3/4 groups were down-regulated in both groups, and the change in E3/3 group was obvious than that of E3/4 group. Conclusion: After treatment with atorvastatin, levels of lipids and ApoE gene expression in ApoE genotype E3/3 patients decreased, which were more evident than E3/4 patients.

Abstract
We report ordering of the cobalt electron configuration in ferromagnetic strained epitaxial LaCoO_{3}. Specifically, the presence of charge order is demonstrated from distinct features of the resonant cobalt contribution to superstructure reflections. Density functional theory calculations show that the observed order is consistent with the spin-state periodicity predicted to give rise to ferromagnetism in LaCoO_{3}. Through the modification of symmetry by strain, concurrent frozen charge and spin-state order are stabilized, giving rise to long-range magnetic order.

Abstract
OBJECTIVE To retrospectively evaluate clinical and radiographic records of chronic periodontitis patients who underwent extraction-orthodontic treatment, in order to determine the effect of the treatment on probing depth, alveolar bone height of teeth adjacent to the extraction sites. METHODS In the study, 33 chronic periodontitis patients who had finished extraction-orthodontic treatment were selected, the periodontal examination system tables and panoramic tomography were recorded before treatment (T0) and after treatment (T1), and the periodontal probing depth (PD), residual alveolar bone height (RBH) of the teeth adjacent to extraction sites (TAES) and the non-teeth adjacent to extraction sites (NTAES) were measured at T0 and T1. RESULTS There was insignificant difference in PD of TAES and NTAES at T0 [(2.40±0.51) mm vs. (2.42±0.55) mm,P>0.05], neither was that at T1 [(2.70±0.67) mm vs. (2.67±0.64) mm, P>0.05]; From T0 to T1, PD of TAES and NTAES had mean increases of 0.3 mm [(2.40±0.51) mm vs. (2.70±0.67) mm,P<0.01] and 0.25 mm [(2.42±0.55 mm vs. (2.67±0.64) mm, P<0.01], respectively. And PD of TAES and NTAES increased from T0 to T1 statistically in the same degree [(0.30±0.64) mm vs. (0.25±0.58) mm,P>0.05]; at T0, RBH of TAES was 0.024 smaller than that of NTAES (0.74±0.16 vs. 0.76±0.16,P<0.05), but there was no difference in RBH between the TAES and NTAES at T1 (0.78±0.14 vs. 0.79±0.12,P>0.05); From T0 to T1, RBH of TAES and NTAES had mean increases of 0.04 (0.74±0.16 vs.0.78±0.14,P<0.05) and 0.02 (0.76±0.16 vs. 0.79±0.12,P<0.05), respectively. And the change of RBH between TAES and NTAES from T0 to T1 had no statistical difference (0.04±0.11 vs. 0.02±0.08,P>0.05)RBH of TAES in the side close to extraction sites was as the same as that of TAES in the side away from the extraction sites at T0 (0.73±0.17 vs. 0.74±0.16,P>0.05). From T0 to T1, RBH of both sides of TAES had mean increases of 0.04 (0.73±0.11 vs. 0.77±0.11,P<0.05) and 0.04 (0.74±0.11 vs. 0.78±0.11,P<0.05), respectively. But for both sides of TAES, from T0 to T1, there was no significant difference in change of RBH (0.04±0.11 vs. 0.04±0.11,P>0.05). CONCLUSIONS With strict control of periodontal inflammation and maintenance of oral hygiene, orthodontic treatment preserves the periodontal conditions in patients with chronic periodontitis, and the extraction-orthodontic treatment can preserve the bone height of the teeth adjacent to extraction sites.

Abstract
OBJECTIVE To explore the clinical efficacy of sequential therapy with voriconazole on chronic obstructive pulmonary disease (COPD) patients in acute phase with pulmonary aspergillosis and its effects on cytokines and pulmonary functions. PATIENTS AND METHODS A total of 110 COPD patients in acute phase with pulmonary aspergillosis who were admitted to the hospital between February 2015 and November 2016 were enrolled. We divided them randomly into two groups, i.e., the control group (n = 55) and the treatment group (n = 55). Patients in the control group took itraconazole capsules orally (200 mg/time, twice per day for three days followed by once per day). Patients in treatment group underwent sequential treatment with voriconazole through intravenous infusion at a dose of 5 mg/kg/time twice a day for 3 days followed by a dose of 4 mg/kg/time, twice a day for 8 days. Then, patients took voriconazole orally at a dose of 150 mL/time, twice a day for 6 days. Patients in two groups received the treatment for a total of 14 days. After treatment, we evaluated the levels of tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), and IL-8. The total lung capacity (TLC), diffusing capacity of the lung for carbon monoxide (DLco), and arterial oxygen saturation (SaO2), were measured as well. RESULTS The total effectiveness rates of the treatment group and the control group were 83.63% and 61.82%. The differences had statistical significance (p < 0.01). After treatment, the incidence of chest pain, cough, sputum-coughing, hemoptysis, cyanosis, and dyspnea in the treatment group was significantly fewer than that in the control group (p < 0.05). TCL, DLco, and SaO2 in the two groups were significantly ameliorated by treatment (p < 0.05). The amelioration in the treatment group was more prominent than that in the control group (p < 0.05). The levels of TNF-α, IL-8, and IL-6 in the two groups were decreased dramatically by the treatments. The decrease in the treatment group was significantly lower than those in the control group (p < 0.05). Occurrence of adverse reactions in treatment group and control group were 8.33% and 6.25%, respectively; (p > 0.05). CONCLUSIONS Sequential therapy with voriconazole exhibits promising clinical efficacy in COPD patients in acute phase with pulmonary aspergillosis. The treatment ameliorated the clinical symptoms and vital signs of patients significantly. It also improved the pulmonary functions and inhibited the inflammatory responses of patients with evident clinical efficacy.

Abstract
Collinear wakefield acceleration has been long established as a method capable of generating ultrahigh acceleration gradients. Because of the success on this front, recently, more efforts have shifted towards developing methods to raise the transformer ratio (TR). This figure of merit is defined as the ratio of the peak acceleration field behind the drive bunch to the peak deceleration field inside the drive bunch. TR is always less than 2 for temporally symmetric drive bunch distributions and therefore recent efforts have focused on generating asymmetric distributions to overcome this limitation. In this Letter, we report on using the emittance-exchange method to generate a shaped drive bunch to experimentally demonstrate a TR≈5 in a dielectric wakefield accelerator.

Abstract
Objective: To explore the impact of weight management and related medication intervention based on body weight changes on cardiac function among patients with chronic congestive heart failure (CHF). Methods: Using prospective, randomized, controlled study methods, consecutive CHF patients, who hospitalized in our department from June 2014 to June 2016 (n=350), were randomly divided into intervention group (n=175) and control group (n=175). Patients in the intervention group received weight management guidance and the post discharge diuretic drugs regimen was adjusted based on body weight changes. The control group received routine medical care post discharge. Left ventricular ejection fraction (LVEF), B type natriuretic peptide precursor (NT-proBNP), 6 minutes walk distance and NYHA classification at one day before discharge and after 6 months were compared between the two groups respectively. Results: Follow-up visit data were not available from 6 patients in the control and intervention group respectively. NYHA classification, LVEF, NT-proBNP and 6 minutes walk distance were similar between the two groups at one day before discharge (all P>0.05). After 6 months, the LVEF and 6 minutes walk distance were significantly higher while NT-proBNP level was significantly lower in the intervention group compared to the control group (all P<0.01). Meanwhile, the LVEF and 6 minutes walk distance were significantly increased, while NT-proBNP was significantly reduced at 6 months post discharge compared to one day before discharge in the intervention group (all P<0.01). The LVEF was also significantly improved (P=0.035), but the NT-proBNP and 6 minutes walk distance were similar (P were 0.328 and 0.807 respectively) at 6 months after discharge compared to one day before discharge in the control group. The NYHA classification was significantly lower in intervention group and in control group at 6 months after discharge compared to one day before discharge (Z=5.154, P<0.01 and Z=10.497, P<0.01), and the NYHA classification improved more in the intervention group than in control group at 6 months after discharge (Z=9.235, P<0.01). The re-hospitalization rate of CHF patients in intervention group was 11.83% (20/169), which was significantly lower than the control group (33.14% (56/169), χ(2)=21.99, P<0.01). At 6 months follow up, body weight remained unchanged in the intervention group, while body weight tended to be higher in the control group compared to one day before discharge. Conclusion: The weight management and diuretic drug regimen adjudgment intervention based on body weight changes can improve cardiac function and reduced re-hospitalization rate in CHF patients.

Abstract
Objective: To evaluate the frailty status and understand the relationship between the incidence of fall and frailty status in the elderly in Beijing. Methods: A cross-sectional study was conducted in old people aged ≥60 years in Longtan community of Dongcheng district in Beijing from November 2015 to January 2016. The information about any fall during the past year and frailty status of the elderly were collected with a standardized structured questionnaire in face-to-face interviews. The frailty status of elderly people was assessed with frailty index (FI) method. Logistic regression analysis was used to explore the relationship between fall and frailty status among the elderly. Results: Among 1 557 old people surveyed, the incidence of fall was 17.8% (277/1 557) during the past year. The incidence of fall in women (21.0%, 192/277) was statistically higher than that in men (13.3%, 85/277) (χ(2)=15.288, P=0.000). The median (quartile) value of FI of the elderly surveyed was 0.09 (0.08); and women had a higher FI median value than men [0.10 (0.08) versus 0.08 (0.07)](Z=5.376, P=0.000). The median FI value (quartile range) of 277 old people with history of fall in previous year was 0.12 (0.11), which was higher than the median FI value of 0.08 (0.07) of 1 280 old people without fall history (Z=7.501, P=0.000). Logistic regression analysis showed that higher FI value was associated with more risks for fall; and FI value showed the greatest impact on the incidence and frequency of fall (OR=1.093, 2.234) compared with other related factors of fall, such as age and gender. Conclusion: Frailty status has a greater impact on both incidence and frequency of fall compared with other factors in elderly people in Beijing; more attention should be paid to weak and old adults in the prevention of fall.

Abstract
In this study, a rapid and specific assay for the detection of porcine circovirus type 3 (PCV3) was established using loop-mediated isothermal amplification (LAMP). Four primers were specifically designed to amplify PCV3. The LAMP assay was effectively optimized to amplify PCV3 by water bath at 60°C for 60 min. The detection limit was approximately 1 × 101 copy in this LAMP assay. Compared to porcine circovirus type 2 (PCV2), both gE and gD genes of pseudorabies virus (PRV) and porcine parvovirus (PPV), the LAMP assay showed a high specific detection of PCV3. A visible detection method was developed using SYBR Green I to recognize the results rapidly. Based on the detection of 20 clinical tissue samples, the LAMP assay was more practical and convenient than classical PCR due to its simplicity, high sensitivity, rapidity, specificity, visibility and cost efficiency.

Abstract
Liver biopsy is not routinely performed in treated chronic hepatitis B. Liver stiffness measurement has been validated for noninvasive liver fibrosis assessment in pretreatment chronic hepatitis B but has not been assessed for fibrosis monitoring during antiviral therapy. Liver stiffness was systemically monitored by Fibroscan® every 6 months in a cohort of patients with hepatitis B receiving antiviral therapy and compared with liver biopsies at baseline and week 104. A total of 534 hepatitis B e antigen-positive treatment-naive patients receiving telbivudine-based therapy with qualified liver stiffness measurement at baseline and week 104 were analyzed, 164 of which had adequate paired liver biopsies. Liver stiffness decreased rapidly (-2.2 kPa/24 weeks) in parallel with alanine aminotransferase (ALT) from 8.6 (2.6-49.5) kPa at baseline to 6.1 (2.2-37.4) kPa at week 24. Interestingly, liver stiffness decreased slowly (-0.3 kPa/24 weeks) but continually from week 24 to week 104 (6.1 vs 5.3 kPa, P < .001) while ALT levels remained stable within the normal range. More importantly, liver stiffness declined significantly irrespective of baseline ALT levels and liver necroinflammation grades. From baseline to week 104, the proportion of patients with no or mild fibrosis (Ishak, 0-2) increased from 74.4% (122/164) to 93.9% (154/164). Multivariate analysis revealed that percentage decline of 52-week liver stiffness from baseline was independently associated with 104-week liver fibrosis regression (odds ratio, 3.742; P = .016). Early decline of 52-week liver stiffness from baseline may reflect the remission of both liver inflammation and fibrosis and was predictive of 104-week fibrosis regression in treated patients with chronic hepatitis B.

Abstract
Background The aim of this study was to evaluate the association between hematinic deficiencies and recurrent aphthous stomatitis (RAS). Material and Methods 517 RAS patients and 187 healthy controls were enrolled in the present study. Hematinic deficiencies, including serum ferritin, folic acid, and vitamin B12 deficiencies were assessed for each participant. Gender and age were taken into account and the collected data were statistically analysed. Results Compared with the healthy controls, a significantly higher overall frequency of hematinic deficiencies was found in RAS patients (p<0.001). When gender and age were taken into account, significant differences in hematinic deficiencies were observed among RAS patients. Serum ferritin deficiency was much more common in young and middle-aged female RAS patients (age<60). Serum folate deficiency and serum vitamin B12 deficiency were both much more common in the young adult group of male RAS patients (21–40 years of age). Logistic regression analysis revealed that both gender and age have significant correlation with the presence of hematinic deficiencies in the RAS patients. Conclusions Significant variations in hematinic deficiencies were demonstrated in RAS patients across different genders and age groups. We suggest that further studies on the hematinic deficiencies of RAS patients should take into account the gender and age of participants. Key words:Recurrent aphthous stomatitis, hematinic deficiencies, gender, age.

Abstract
Objective: To evaluate the incidence and factors related to daytime hypercapnia in Han and Uygur patients with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods: There were 221 patients with OSAHS (include 179 Han patients and 42 Uygur patients) in Sleep Center of Department of Respiratory and Critical Care Medicine of Karamay Central Hospital from 2015, Jan to Dec. All the patients underwent polysomnography (PSG), nocturnal oximetry, daytime blood gas analysis, pulmonary function test and Mouth occlusion pressure (P0.1) results were recorded. The features of hypercapnia was analyzed for patients with OSAHS, and linear regression analysis was used to evaluate the arterial carbon dioxide partial pressure (PaCO2) levels and related factors. Results: Daytime hypercapnia occurred in 16.7% (37/221) of the 221 patients with OSAHS. Compare with no hypercapnia groups, the body mass [(31.6±5.6) vs (27.9±1.7) kg/m2], sleep apnea index (AHI) [(40.9±26.3) vs (32.2±20.1) times/h], the percentage of time spent at oxygen saturation below 90 (SIT90) [(38.6±31.9)% vs (23.9±23.6)%], P0.1 [(3.08±2.86) vs (2.03±1.20) mmHg, 1 mmHg=0.133 kPa] were higher in hypercapnia groups, but the mean nocturnal arterial oxygen saturation (MSaO2) [(86.0±15.5)% vs (92.0±3.0)%], the nadir arterial oxygen saturation (LSaO2) [(68.9±13.0)% vs (75.3±9.9)%] and arterial partial pressure of oxygen (PaO2) [(74.5±23.0) vs (86.1±14.8) were lower in hypercapnia groups (all P<0.05). Compare with Han patients with OSAHS, MSaO2 and LSaO2 was lower, PaCO2 and P0.1 was higher in Uygur patients (all P<0.05). Conclusions: Uygur OSAHS patients with hypercapnia have a higher daytime PaCO2 than the Han counterparts. BMI, AHI, MSaO2, P0.1 level are all related with daytime hypercapnia in OSAHS.

Abstract
Objective: To compare the efficacies of cross priming amplification (CPA) and RealAmp with XpertMTB/RIF for the diagnosis of pulmonary tuberculosis(TB) at peripheral microscopic centers. Methods: From December of 2014 to December of 2015, 3 193 patients suspected with TB were enrolled consecutively at 3 county level TB clinical clinics in Zhongmu, Xinmi and Dengzhou of Henan province. Totally 3 193 collected sputum samples were detected by smear microscopy, L-J media culture, CPA, RealAmp and Xpert MTB/RIF. The culture positive samples were tested by MPB64 for strain identification. The sensitivity and specificity of CPA, RealAmp and Xpert MTB/RIF were calculated according to L-J solid culture results and clinical diagnosis results. Results: The sensitivity of CPA, RealAmp and Xpert MTB/RIF were 85.5%(413/483), 85.5%(413/483) and 87.9%(422/480), respectively, compared with L-J solid culture, the difference among the 3 methods being not significant(χ(2)=1.6, P>0.05). The specificity of CPA, RealAmp and Xpert MTB/RIF were 96.8%(2 624/2 170), 93.2%(2 527/2 170) and 95.3%(2 567/2 170) compared with culture; and there was a significantly statistic difference among the 3 methods(χ(2)=37.8, P<0.001). The sensitivity of smear microscopy, culture, CPA, RealAmp and Xpert MTB/RIF was 21.7%(300/1 383), 34.9%(483/1 383), 34.6%(478/1 383), 39.2%(542/1 383) and 38.1%(526/1 381) compared with clinical diagnosis. The sensitivity of CPA, RealAmp and Xpert MTB/RIF was higher than that of smear (χ(2) =31.9, P<0.01), but there was no significantly statistic difference between the 3 molecular methods(χ(2)=2.9, P>0.05). The specificity of smear microscopy, L-J solid culture, CPA, RealAmp and Xpert MTB/RIF was 100%(1 810/1 810), 100%(1 810/1 810), 98.8%(1 789/1 810), 98.8%(1 756/1 810) and 97.0%(1 788/1 810), and there was no significantly statistic difference among the 3 molecular methods(χ(2)=0.16, P>0.05). Conclusion: The capability of CPA and RealAmp for diagnosing pulmonary TB was similar to Xpert MTB/RIF.The former 2 methods were more suitable to apply to the diagnoses of pulmonary TB in peripheral laboratories.

Abstract
Methanol as a green and renewable resource can be used to generate hydrogen by reforming, i.e., its catalytic oxidation with water. In combination with a fuel cell this hydrogen can be converted into electrical energy, a favorable concept, in particular for mobile applications. Its realization requires the development of novel types of structured catalysts, applicable in small scale reactor designs. Here, three different types of such catalysts were investigated for the steam reforming of methanol (SRM). Oxides such as TiO2 and CeO2 and mixtures thereof (Ce1Ti2Ox) were deposited inside a bulk nanoporous gold (npAu) material using wet chemical impregnation procedures. Transmission electron and scanning electron microscopy reveal oxide nanoparticles (1-2 nm in size) abundantly covering the strongly curved surface of the nanoporous gold host (ligaments and pores on the order of 40 nm in size). These catalysts were investigated in a laboratory scaled flow reactor. First conversion of methanol was detected at 200 °C. The measured turn over frequency at 300 °C of the CeOx/npAu catalyst was 0.06 s-1. Parallel investigation by in situ infrared spectroscopy (DRIFTS) reveals that the activation of water and the formation of OHads are the key to the activity/selectivity of the catalysts. While all catalysts generate sufficient OHads to prevent complete dehydrogenation of methanol to CO, only the most active catalysts (e.g., CeOx/npAu) show direct reaction with formic acid and its decomposition to CO2 and H2. The combination of flow reactor studies and in operando DRIFTS, thus, opens the door to further development of this type of catalyst.

Abstract
Objective: To investigate the correlation between nucleolus spindle-related protein 1 (NUSAP1) and malignant progression and prognosis of human glioblastoma multiforme (GBM). Methods: RT-PCR and immunohistochemical technique were applied to analyze NUSAP1 expression level in GBM surgical specimens. Correlations between NUSAP1 expression and molecular classification and survival of patients with GBM were also investigated in TCGA database. The gene silencing technique was used to silence NUSAP1 expression in U87 cells, CCK-8 assay was used to detect cell proliferation, flow cytometry was used to detect cell cycle changes, and in vivo tumorigenicity was evaluated after NUSAP1 silencing in tumor-bearing mice. Results: NUSAP1 expression level in GBM was higher than that in non-tumor brain tissue. Survival curve analysis showed that the survival time of GBM patients with high NUSAP1 expression decreased significantly (P<0.01). NUSAP1 expression was relatively lower in mesenchymal and neural molecular subtypes of GBM, when compared with the other two molecular subtypes. And it was closely related with specific genetic aberrations (such as PTEN loss and IDH1 mutation). Silencing NUSAP1 inhibited G2/M cell cycle progression of GBM cells, and inhibited cell proliferation both in vitro and in vivo. Conclusion: Expression of NUSAP1 is closely related to progress and prognosis of GBM, and can be a biomarker reflecting GBM prognosis and act as a therapeutic target with potential clinical application value.
