Abstract
Objective: To analyze the correlation between urinary albumin/creatinine ratio (ACR) and 24-hour urinary microalbumin (UMA) and evaluate the predictive value of ARC for early diabetic nephropathy. Methods: A total of 368 patients with type 2 diabetes mellitus were retrospectively collected. Early diabetic nephropathy was defined as 24h UMA 30~<300 mg/24h. The correlation between ACR and 24hUMA, and the area under the receiver operating characteristic (ROC) curve of ACR in diagnosis of early diabetic nephropathy were calculated. Gender, age, course of disease, fasting venous blood glucose, glycosylated hemoglobin, blood pressure, triglyceride and total cholesterol were used as adjusting variables to establish univariate and multivariate logistic models of ACR for early diabetic nephropathy, respectively. A regression model was used to evaluate the diagnostic value of ACR for early diabetic nephropathy. Results: The correlation between ACR and 24h UMA was 0.658. The area under ROC curve of ACR for early diabetic nephropathy was 0.907 before and 0.933 after adjustments of gender, age, course of disease, fasting venous blood glucose, glycosylated hemoglobin, blood pressure, triglyceride and total cholesterol, respectively. The OR value of ACR of diabetic nephropathy was 2.016 before and 2.762 after same adjustments. The calibration of Hosmer-Lemeshow chi-square test evaluation model was 19.362 before (P=0.13) and 14.928 after adjustments (P=0.061). Conclusion: ACR is a better predictor for early diabetic nephropathy although its value is influenced by gender, age, course of disease, blood sugar, lipid, and blood pressure.

Abstract
Objective: To investigate the inhibitory effect of AKR1B10 inhibitor combined with sorafenib on hepatocellular carcinoma (HCC) xenograft growth. Methods: HepG2 xenograft model was established in nude mice. The mice were then randomly divided into four groups: control group, epalrestat monotherapy group, sorafenib monotherapy group and combination treatment group. Tumor volume, tumor weight, T/C ratio and the change in body weight of nude mice in each group were compared to evaluate the curative effect. Immunohistochemistry staining was used to detect the expression of Ki-67 in tumor tissues to evaluate the proliferation status of tumor cells. One-way analysis of variance was used to compare the differences between the groups. Student's t-test was used to test means of two groups and chi-square test was used for multiple samples. Results: The differences of the grafted tumor volume before and after treatment between the control group, epalrestat group, sorafenib group and combined therapy group was 238.940 ± 39.813, 124.991 ± 84.670, -26.111 ± 11.518, and -54.072 ± 17.673(mm(3)), respectively, (F = 37.048, P < 0.001). The tumor mass were 0.273 ± 0.140, 0.158 ± 0.078, 0.079 ± 0.054, 0.045 ± 0.024 (g), (F = 16.594, P < 0.001); T/C ratio were 100%, 57.9%, 28.9%, 16.5%, and Ki-67 positive rate were 23.295 ± 6.218, 13.503 ± 3.392, 7.325 ± 2.257, 4.664 ± 1.189 (%), (χ(2) = 822.203, P < 0.001) . The tumor volume (t = -3.579, P = 0.002) and Ki-67 positive rate (t = -10.003, P < 0.001) in epalrestat monotherapy group were significantly lower than control group. The tumor volume (t = 2.056, P = 0.025), tumor mass (t = 2.101, P = 0.043), and Ki-67 positive rate (t = -2.850, P = 0.005) in combination treatment group were significantly lower than sorafenib monotherapy group. Compared with the control group, the body weight of nude mice in the treatment group decreased to a certain extent, but there was no statistically significant difference between epalrestat monotherapy group and control group (t = -1.599, P = 0.262), and combined therapy and sorafenib monotherapy group (t = -0.051, P = 0.96). Conclusion: AKR1B10 inhibitor enhanced the inhibitory effect of sorafenib on hepatocellular carcinoma xenograft.

Abstract
Egg drop syndrome virus (EDSV), a member of the family Adenoviridae and an economically important pathogen with a broad host range, leads to markedly decreased egg production. However, the molecular mechanism underlying the host-EDSV interaction remains unclear. Here, we performed high-throughput RNA sequencing (RNA-Seq) to study the dynamic changes in host gene expression at 6, 12, and 24 hours post-infection in duck embryo fibroblasts (DEFs) infected with EDSV. Atotal of 441 differentially expressed genes (DEGs) were identified after EDSV infection. Gene Ontology category and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that these DEGs were associated with multiple biological functions, including signal transduction, host immunity, virus infection, cell apoptosis, cell proliferation, and pathogenicity-related and metabolic process signaling pathways. We screened and identified 12 DEGs for further examination by using qRT-PCR. The qRT-PCR and RNA-Seq results were highly consistent. This study analyzed viral infection and host immunity induced by EDSV infection from a novel perspective, and the results provide valuable information regarding the mechanisms underlying host-EDSV interactions, which will prove useful for the future development of antiviral drugs or vaccines for poultry, thus benefiting the entire poultry industry.

Abstract
MiR-222-3р has been implicated in tumor cell proliferation and has an important role in the differentiation and maturation of myogenic cells. However, its role in skeletal myoblast proliferation is still unclear. In this study, we found that miR-222-3р expression increases initially and then decreases during C2C12 myoblast proliferation. Using synthetic miRNA mimics and inhibitors in gain- or loss-of-function experiments, we snowed that miR-222-3р overexpression in C2C12 cells promotes myoblast proliferation and represses myofiber formation, while miR-222-3р downregulation has the opposite effect. Using a prediction program, BTG2 was identified as a possible target gene of miR-222-3р. During myogenesis, miR-222-3р mimics repress BTG2 expression, while miR-222-3р inhibitors promote BTG2 expression. Using dual-luciferase reporter assay, we further demonstrated that miR-222-3р specifically targets BTG2. Additionally, we show that siRNA-mediated downregulation of BTG2 expression in C2C12 myoblasts promotes the proliferation and suppresses differentiation. In conclusion, we provide a novel insight into the mechanism by which miR-222-3р regulates the proliferation and differentiation of C2C12 myoblasts by targeting BTG2. This information contributes to our understanding of the role of miRNAs in skeletal muscle development.

Abstract
OBJECTIVE To discuss the lag effects of daily average temperature on the daily cases of bacillary dysentery in Lanzhou city. METHODS The data of daily cases of bacillary dysentery were collected during 2008 and 2015 in the city, and the meteorological data at the same period was integrated. The distributed lag non-linear model was used to analyze the relevance between daily average temperature and the daily cases of bacillary dysentery. RESULTS The exposure response relationship between the daily temperature and the incidence of bacillary dysentery was "J" type, the lowest incidence temperature was 17 °C, and the effect of high temperature on different gender and age groups was higher than that of the intermediate effect. The effect of high temperature and intermediate effect on the male and female groups showed an acute effect, the effect of the day was the highest, followed by fluctuations in temperature, and the greater the impact on women. In different age groups, high temperature effect and the intermediate effect of bacterial dysentery in 0-3 years old groups were the biggest; the effects of high and intermediate temperature on people aged 0-3 and 19-64 year all showed acute effects, which were the maximum value at the day, then decreased volatility; and for people aged over 65 years, the day after the onset, decreases and then increases slowly. There were obviously increasing risks of bacillary dysentery both the high temperature (32 °C) and the middle temperature (26 °C) with respect to 17 °C. The accumulative effects were highest at lag14 days, and the RR (95%CI) values of middle temperature was 2.30 (1.53-3.13), 2.45 (1.65-3.30), 2.41 (1.59-3.28), 2.54 (1.40-3.79), 1.82 (0.41-3.43), 1.98 (1.11-2.93), and 1.73 (0.68-2.88) among the males, females, 0-3 years old, 4-11 years old, 12-18 years old, 19-64 years old and over 65 years old people, respectively; while the high temperature was 2.93 (1.38-4.69), 3.08 (1.48- 4.90), 3.26 (1.60-5.16), 3.12 (1.06-5.56), 1.94 (0.73-5.39), 2.31 (0.54-4.36), and 2.06 (0.02-4.51), respectively. CONCLUSION The high temperature may increase risks of bacillary dysentery, and the females and younger people were the sensitive population. Meteorological factors play an important role in the occurrence and development of bacillary dysentery in Lanzhou. The incidence of bacillary dysentery is affected by multiple meteorological factors, but the primary one is high temperature. The temperature has not a direct effect on the incidence of bacillary dysentery, but an indirect influence in different populations through the impacts of various aspects of the incidence of bacterial dysentery (residents living habits, communication channels and the habits of the susceptible population).

Abstract
Objective:The study aims to assess the effect of tympanoplasty without mastoidectomy for the middle ear under different infected states.Method:One hundred and thirteen cases (113 ears) with chronic otitis media (COM) received tympanoplasty without mastoidectomy. All the patients were found inflammatory proliferative lesions in the mastoid and tympanic antrum via CT scan before surgery and were followed up over 1 year. The patients were placed into the infected ear group (72 ears) and uninfected ear group (41 ears) according to the infective condition. We used SPSS statistical software to analyze the efficacy.Result:Of 113 cases, 92 ears had dry ear canals in 1/2 to 1 month after surgery, and the negative air pressure in the tympanum gradually disappeared in 3-6 months after surgery. Of the 72 ears in the infected ear group, 69 ears had postoperative dry ears, and a large amount of intraoperative purulent secretion was seen in the tympanum in 4 cases, which all had dry ear canals. Three cases had relapse, for a dry ear canal rate of 95.8%. Three ears showed dry tympanic membrane perforations, and effective ears with air-bone conduction differences smaller than or equal to 20 dB accounted for 51.4% of cases. Of the 41 ears in the uninfected group, 40 ears had postoperative dry ears, 1 case had relapse, for a dry ear canal rate of 97.6%. Two ears showed dry tympanic membrane perforations. Effective ears with air-bone conduction differences smaller than or equal to 20 dB accounted for 48.8% of cases. No case of facial paralysis, dizziness, formation of invaginations of the tympanic membrane and cholesteatoma were seen in the patients included in this study during the follow-up visits.Conclusion:Whether there are inflammatory proliferative lesions in the mastoidor not, tympanoplasty without mastoidectomy is feasible for chronic active otitis media. Moreover, different infection statuses of the middle ear do not cause difference in the postoperative relapse rate and hearing improvement.

Abstract
Objective: To investigate the overall efficacy of early breast cancer after breast-conserving treatment. To analyze risk factors affecting local regional recurrence (LRR), distant metastasis (DM) and survival. Methods: 1 791 breast cancer patients treated with breast-conserving surgery were retrospectively analyzed. The inclusion criteria were pathologic diagnosis of invasive breast cancer without supraclavicular and internal mammary node metastasis, T1-2N0-3M0, and no neoadjuvant therapy. Univariate analysis of survival was performed by Kaplan-Meier method and log rank test. Cox regression model was used for multivariate analysis. Results: The median follow-up time was 4.2 years. For all patients, the 5-year LRR, DM, disease-free survival(DFS) and overall survival(OS) rates were 3.6%, 4.6%, 93.0% and 97.4%, respectively. The LRR rates of patients with Luminal A, Luminal B1, Luminal B2, HER-2 over-expressed and triple-negative breast cancer were 2.0%, 6.1%, 5.9%, 0 and 10.0%, while the DM rates were 3.2%, 6.7%, 8.3%, 4.8% and 7.3%, respectively. Among the N0 patients, axillary dissection was performed in 689 cases and sentinel lymph node biopsy in 652 cases. The 5-year LRR rates were 3.3% and 3.2% (P=0.859), and the OS rates were 98.2% and 98.3% (P=0.311) respectively, which showed no statistically significant. There were 1 576 patients that underwent postoperative radiotherapy. Postoperative radiotherapy significantly reduced the 5-year LRR compared with surgery alone (2.5% vs 12.9%). The 5-year LRR rates of patients who received conventional fractionated radiotherapy and hypo-fractionated radiotherapy were 2.7% and 3.1%, respectively. But the difference was not statistically significant (P=0.870). Multivariate analysis showed that age, lymphovascular invasion, pathological T staging, postoperative radiotherapy, ER/PR status and endocrine therapy were independent factors of LRR in breast cancer patients (all P<0.05). Histological grade and pathological N staging were independent factors of DM (all P<0.05). The age, lymphovascular invasion, pathological T and N staging, postoperative radiotherapy, ER/PR status and endocrine therapy were independent factors for DFS (all P<0.05). Histological grade, pathological N staging, ER/PR status and endocrine therapy were factors for OS (all P<0.05). Conclusions: With contemporary standard treatment, the recurrence rate of early breast cancer after breast conserving treatment is less than 10%. Node-negative patients after sentinel lymph node biopsy did not need axillary dissection. The overall utilization of radiotherapy after breast conserving surgery is satisfactory. Hypofractionated radiotherapy is as effective as conventional fractionated radiotherapy. Local regional recurrence and distant metastasis have different risk factors.

Abstract
Objective: To investigate the clinical outcome of expression discordance of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) in primary breast cancer and the corresponding metastatic lesions. Methods: A retrospective analysis was performed on 178 breast cancer patients with metastasis confirmed by the National Cancer Center & Cancer Hospital, Chinese Academy of Medical Sciences in the past 6 years. The data of expressions of ER, PR and HER-2 in primary and metastatic breast cancer, the metastatic sites, disease progression were collected and the relationships of the expression discordance of receptors with prognosis were analyzed. Results: The discordance rates of ER, PR and HER-2 between the primary tumor and the metastatic sites were 27.0%, 39.8% and 18.7%, respectively. The discordance rates of ER, PR and HER-2 of patients with locoregional recurrence were 21.9%, 36.6% and 12.7%, respectively, while those of patients with distant metastases were 31.3%, 42.7% and 23.8%. The median progression free survivals (PFS) of ER+/+、ER+/-、ER-/+、ER-/- of primary tumor and metastatic sites were 17.7 months, 10.3 months, 14.0 months and 9.0months, respectively (P=0.025). The median PFS of PR+/+, PR+/-, PR-/+, PR-/- were 23.0 months, 10.7 months, 14.0 months and 9.2months, respectively (P=0.002). The median PFS of HER-2+/+, HER-2+/-, HER-2-/+, HER-2-/- were 14.9 months, 15.2 months, 12.3 months and 14.0 months, respectively, without significant differences (P=0.588). Conclusions: This study confirms that expression discordances of ER, PR and HER-2 between primary breast cancer and the corresponding metastatic lesions are dramatic, especially in the patients with distant metastasis. The unstable levels of ER and PR seem to be significantly associated with prognosis of breast patients.

Abstract
Hepatic encephalopathy (HE) is caused by severe liver disease or portal shunt. Metabolic disorders and central nervous system dysfunctions are the main symptoms of this syndrome. Ammonia is considered to play a central role in the pathogenesis of HE. Helicobacter pylori (H. pylori) have been suggested as a possible source of ammonia production because of its high urease content. However, the relationship between H.pylori and blood ammonia and HE, as well as the therapeutic effect of H.pylori eradication on HE, is inconclusive, and the results are full of contradictions. The aim of this review is to summarize current knowledge on the association of H. pylori with HE and to address the question of whether H. pylori eradication may be beneficial in the management of HE.

Abstract
Vitamin C, vitamin E, and alpha-lipoic acid (ALA) are potent nutritional antioxidants, which are important for enhancing immunity. This study compared the effects of supplementation with vitamin C, vitamin E, or ALA on the antioxidant defense system and the expression of immune-related genes under oxidative stress induced by dexamethasone (DEX) in broilers. In total, 240 one-day-old female Recessive White Rock chickens were assigned randomly to either a basal diet (control group) or basal diet supplemented with vitamin C (200 mg/kg diet), vitamin E (100 mg/kg), or ALA (500 mg/kg) for 28 d starting from hatching. At 21 d of age, birds fed the ALA-supplemented diet had the highest plasma total antioxidant capacity (T-AOC) and superoxide dismutase (T-SOD) and glutathione peroxidase (GSH-PX) enzyme activities, and the lowest plasma malondialdehyde (MDA) activity, as well as the lowest mRNA gene expression levels of interferon gamma (IFN-γ) and lipopolysaccharide-induced tumor necrosis factor-alpha factor (LITAF). At 23 d of age, the broilers in the 3 treatment groups were injected in the thigh muscle with DEX for 3 alternating days. In addition, the control group was divided into 2 equal groups, in which one was injected with saline and the other was injected with DEX. At 28 d of age, the DEX-ALA group (P < 0.05) had the highest activity levels for T-AOC, T-SOD, and GSH-PX in the plasma and liver (P < 0.05), and the greatest reduction in the MDA level. Dietary ALA significantly decreased the mRNA expression levels of the interleukin 1 β (IL-1β), IL-6, IFN-γ, and LITAF genes compared with the other groups during oxidative stress by DEX. In conclusion, this study suggests that in broilers, ALA is more effective for normalizing the oxidative stress induced by DEX than vitamin C or vitamin E.

Abstract
This study aims to analyze the clinical characteristics of breast invasive ductal carcinoma (BIDC) in patients with different molecular subtypes and identify possible correlation to prognosis. miR- 10b expression level was detected using real-time quantitative polymerase chain reaction (RT-PCR). Tissue sections were collected and stained using the immunohistochemical method. The samples were grouped into human epidermal growth factor receptor 2, (HER2) overexpression, Triple negative, Luminal A and Luminal B groups. Age, tumor size, breast cancer molecular subtype, clinical stage, miR-10b positive expression, positive expression of Ki-67 and survival rate of patients diagnosed with BIDC were analyzed. The expression of miR-10b was down-regulated in the breast carcinoma tissues. Age and clinical stage were distinctly different among patients with different molecular subtypes of BIDC (p less than 0.05). Tumor size was not remarkably different (p less than 0.05) among different subtypes. The positive expression rate of miR-10b was lowest in patients with Luminal B BIDC; the positive expression of Ki-67 was in different correlation with the expression of different receptors, and there was a remarkable difference (p less than 0.05); moreover, the survival rate of patients with Luminal A and B BIDC was significantly higher compared to patients with other molecular subtypes (p less than 0.05). Clinical characteristics and prognosis of BIDC vary among different molecular subtypes. This study provides valuable input on BIDC therapy.

Abstract
Objective: To explore the regulation and mechanism of Prestin protein by identifying the proteins interacted with Prestin in cochlear outer hair cell(OHC) and analyzing their biological function. Methods: Co-immunoprecipitation combined mass spectrometry technology was used to isolate and identify the proteins interacted with Prestin protein of OHC, bioinformatics was used to construct Prestin protein interaction network. The proteins interacted with Prestin in OHC of guinea pig were determined by matching primary interaction mass spectrometry with protein interaction network, and annotated their functions. Results: The results of co-immunoprecipitation combined with mass spectrometry showed that 116 kinds of credible proteins could interact with Prestin. By constructing Prestin protein interaction network, matching the results of mass spectrometry and analyzing of sub-cellular localization, eight kinds of proteins were confirmed that they interacted with Prestin directly, namely EEF2, HSP90AB1, FN1, FLNA, EEF1A1, HSP90B1, ATP5A1, and ERH, respectively, which were mainly involved in the synthesis and transportation, transmembrane folding and localization, structural stability and signal transduction of Prestin protein. Conclusion: EEF2, HSP90AB1, FN1, FLNA, EEF1A1, HSP90B1, ATP5A1 and ERH provide molecular basis for sensory amplification function of OHCs by participating in biotransformation, transmembrane folding and localization, signal transduction and other biological processes of Prestin protein.

Abstract
Objective: To study the characteristics of gene mutations in Chinese myelodysplastic syndromes (MDS) patients. Methods: A total of 511 Chinese patients with MDS performed 112-gene targeted sequencing were retrospectively analyzed. Results: Eighty-three distinct mutant genes were found in 511 patients with MDS. Amongst these, the most frequent mutations was associated with epigenetics (50%) , followed by spliceosome (37%) , signal transduction (34%) , transcription factors (24%) and cell cycle/apoptosis (17%) . 439 subjects (86%) had at least one gene mutation. The mean number of mutations in refractory anemia with unilineage dysplasia (RCUD) was 1.25, refractory anemia with multilineage dysplasia (RCMD) was 1.73, refractory anemia with ring sideroblasts (RARS) was 2.79, refractory anemia with excess blasts-1 (RAEB-1) was 2.22, RAEB-2 was 2.34, MDS with isolated 5q- was 2.67, MDS, unclassified (MDS-U) was 2.00. U2AF1 mutant subjects were more likely to have isolated+8[Q<0.001, OR=4.42 (95% CI 2.23-8.68) ]and less likely to have complex karyotypes[Q=0.005, OR=0.22 (95% CI 0.04-0.72) ]. According to the number of gene mutations, all subjects were categorized into three groups, namely group with 0-1 mutation, with 2 mutations and with three or more mutations. There was a significant difference in overall survival (OS) among three groups (P=0.041) . Conclusion: About 90% patients with MDS have at least one gene mutation. Genes associated with epigenetics and spliceosome are most common mutated genes in MDS. The increased numbers of gene mutations accompany with disease evolution and associate with poor prognosis.

Abstract
BACKGROUND This phase I/II clinical trial investigated S-1 administered with intensity-modulated radiotherapy (IMRT) as adjuvant therapy for node-positive gastric cancer. Patients had undergone radical resection and D1/D2 lymph node dissection. METHODS In phase I, patients received adjuvant chemoradiotherapy of IMRT (45 Gy in 25 fractions) with concurrent S-1 administered on a dose-escalation schedule to determine the recommended dose (RD). In phase II, the safety and efficacy of the RD of S-1 combined with IMRT were assessed. RESULTS We consecutively enrolled 73 patients (56 men; median age, 53 years; range, 29-73 years) and the phase I portion of the study included 27 patients. The RD of S-1 administered concomitantly with IMRT was 80 mg m-2 day-1 orally, twice daily. The phase II analysis included 52 patients (46 new patients plus 6 from phase I). 8 patients (15.4%) developed grade 3 or 4 toxicities. There were 21 recurrence events and 15 deaths (1 bowel obstruction, 14 gastric cancer). Three-year disease-free survival and overall survival were 62.2% (95% confidence interval (CI), 48.5-75.9) and 70.0% (95% CI, 56.3-83.7), respectively. The median time to recurrence was 17.5 months (range, 3.8-42.0). The median time from recurrence to death was 7.0 months (range, 1.5-28.7). CONCLUSIONS S-1 combined with IMRT adjuvant chemoradiotherapy is safe and efficacious for advanced gastric cancer.

Abstract
An asymmetric bis(dithienylethene-acetylide) ruthenium(II) complex trans-Ru(dppe)2(L1o)(L2o) (1oo) incorporating two different dithienylethene-acetylides (L1o and L2o) was designed to modulate multistate photochromism in view of the well separated ring-closing absorption bands between L1o and L2o. Upon irradiation with appropriate wavelengths of light, complex 1 undergoes stepwise photocyclization and selective photocycloreversion to afford four states (1oo, 1co, 1oc, and 1cc). As a contrast, symmetric complexes trans-Ru(dppe)2(L1o)2 (2oo) and trans-Ru(dppe)2(L2o)2 (3oo) with two identical dithienylethene-acetylides were synthesized, and the corresponding photochromic behavior was investigated. The photochromic properties of the oxidized species (1oo+/1co+/1oc+/1cc+, 2oo+/2co+/2cc+, and 3oo+/3co+/3cc+) were also investigated. The ring-closing absorption bands of one-electron oxidized species 1oo+, 2oo+, and 3oo+ show obvious blue shifts relative to those of 1oo, 2oo, and 3oo, respectively. The ring-closing absorption bands in both neutral and oxidized species grow progressively following oo → oc/co → cc and oo+ → oc+/co+ → cc+. As revealed by spectroscopic, electrochemical, and computational studies, complex 1 displays eight switchable states through stepwise photocyclization, selective cycloreversion, and a reversible redox process.

Abstract
Fragile X-associated tremor/ataxia syndrome (FXTAS) is a late-onset neurodegenerative disorder affecting approximately 45% of male and 16% of female carriers of the FMR1 premutation over the age of 50 years. Currently, no effective treatment is available. We performed an open-label intervention study to assess whether allopregnanolone, a neurosteroid promoting regeneration and repair, can improve clinical symptoms, brain activity, and magnetic resonance imaging (MRI) measurements in patients with FXTAS. Six patients underwent weekly intravenous infusions of allopregnanolone (2-6 mg over 30 min) for 12 weeks. All patients completed baseline and follow-up studies, though MRI scans were not collected from 1 patient because of MRI contraindications. The MRI scans from previous visits, along with scans from 8 age-matched male controls, were also included to establish patients' baseline condition as a reference. Functional outcomes included quantitative measurements of tremor and ataxia and neuropsychological evaluations. Brain activity consisted of event-related potential N400 word repetition effect during a semantic memory processing task. Structural MRI outcomes comprised volumes of the hippocampus, amygdala, and fluid-attenuated inversion recovery hyperintensities, and microstructural integrity of the corpus callosum. The results of the study showed that allopregnanolone infusions were well tolerated in all subjects. Before treatment, the patients disclosed impairment in executive function, verbal fluency and learning, and progressive deterioration of all MRI measurements. After treatment, the patients demonstrated improvement in executive functioning, episodic memory and learning, and increased N400 repetition effect amplitude. Although MRI changes were not significant as a group, both improved and deteriorated MRI measurements occurred in individual patients in contrast to uniform deterioration before the treatment. Significant correlations between baseline MRI measurements and changes in neuropsychological test scores indicated the effects of allopregnanolone on improving executive function, learning, and memory for patients with relatively preserved hippocampus and corpus callosum, while reducing psychological symptoms for patients with small hippocampi and amygdalae. The findings show the promise of allopregnanolone in improving cognitive functioning in patients with FXTAS and in partially alleviating some aspects of neurodegeneration. Further studies are needed to verify the efficacy of allopregnanolone for treating FXTAS.

Abstract
Objective: The association between endometrial stimulation and the intrauterine insemination outcome remains to be a controversial issue, for there being all kinds of conflicting data in the existing literatures. We conducted a Meta-analysis case to verify the relations between endometrial stimulation and intrauterine insemination (IUI). Methods: The articles had been searched in the following online databases: MEDLINE, CNKI, VIP, Wan Fang, EMBASE and the Cochrane Library. All of the statistics quoted for our studies have been published in English or Chinese from Jan, 2000 to May, 2016. Among the 6 studies included in this Meta-analysis, all of them used a case - control design. All the 6 studies evaluated a total of 1349 participants, including 734 cases of endometrial injury. Results: The results of the Meta-analysis showed that patients with endometrial stimulation were more likely to receive clinical pregnancy than those who did not. Compared with the control group, the clinical pregnancy rate of experiment group was higher (RR=0.88, 95% CI: 0.82-0.95, P=0.001), while the differences between their abortion rate (RR=0.72, 95% CI: 0.37-1.4, P=0.33) and multiple pregnancies rate (RR=0.78, 95% CI: 0.3-2.01, P=0.60) were insignificant. Conclusions: Endometrial stimulation could help increase the pregnancy rate in IUI cycles, while the abortion rate and multiple pregnancies rate would not be raised.

Abstract
OBJECTIVE To analyze the clinical pathologic characteristics of cases with fluorescence in situ hybridization (FISH) positive of exfoliated urothelial cells, so as to evaluate the clinical utility of FISH in the diagnosis of urothelial carcinoma (UC). METHODS A total of 271 cases of FISH positive in Department of Urology of Peking University First Hospital from Apr. 2012 to Sep. 2015 were recruited in this study. Retrospective analysis was made on their clinical data. For FISH analysis, labeled probes specific for chromosomes 3, 7, 17, and the p16 (9p21) gene were used to assess chromosomal abnormalities indicative of malignancy. The positive predict values (PPV) of all the techniques were analyzed. RESULTS Of the 271 patients, 207 cases were UC, 7 cases were non-UC, and 57 cases were benign diseases. The PPV of FISH in detecting UC was 76.4%, while the 95% confidence interval (CI) 71.3% to 81.5%. In the cohort of FISH positive, this value was similar to that of urinary cytology (PPV 86.8%, 95% CI: 78.5%-95.0%). The PPV of FISH was lower than that of cystoscopy and ureteroscopy (PPV 96.1%, 95% CI: 91.7%-100.0%). There were significant differences between this study and the PPV of FISH reported abroad (PPV 53.9%, χ2=33.048, P<0.001). Of all the UC with FISH positive, bladder cancer showed an earlier pathological stage versus renal pelvic carcinoma and ureteral carcinoma, with significance (χ2=5.894, P=0.015, and χ2=13.601, P<0.001, respectively). However, no difference was found in the size, pathological stage and pathological grade of tumors between the urinary cytology positive group and the urinary cytology negative group. The rate of high-grade UC in ureteral carcinoma of FISH positive was 92.3%, much higher than that of ureteral carcinoma reported domestically. CONCLUSION The PPV of FISH in detecting UC is higher relatively, with a better clinic value for Chinese patients. The ureteral carcinoma with FISH positive obtains a higher pathological grade, which is of great guiding significance for UC.

Methods: (1) Placental tissues were collected from patients with mild pre-eclampsia (mPE, n=30), severe pre-eclampsia (sPE, n=30) and normal pregnant women (n=40). Human choriocarcinoma cell lines JAR and JEG3 were assigned to the miR-106b mimics group, the mimics negative control group, the miR-106b inhibitor group and the inhibitor negative control group, respectively. (2) The target gene of miR-106b(such as MMP-2) was predicted by bioinformatics. Dual-luciferase reporting system was used to verify the regulation of miR-106b on the expression of MMP-2. (3) The expressions of miR-106b and MMP-2 were measured by quantitative real-time PCR (qRT-PCR) and western blot. (4) Cell proliferation was determined by MTT assay. (5) Invasive activities in each group were assessed by cell transwell invasion assays. Results: (1) Predicting result of bioinformatics indicated that MMP-2 was one of the target genes of miR-106b. Dual-luciferase activity assay demonstrated that MMP-2 was the direct target of miR-106b (P<0.01) .(2) The results of qRT-PCR.①The expression of miR-106b in the placentas of mPE, sPE, normal pregnant women were 2.89±0.04, 1.96±0.03, 1.01±0.03, respectively (P<0.05).

And its expression in the JEG3 cell line were 2.17±0.04, 1.18±0.04, 0.61±0.03 and 1.22±0.03, respectively (P<0.05). ③The expression of MMP-2 mRNA in the JAR cell line in the miR-106b mimics group, the mimics negative control group, the miR-106b inhibitor group and the inhibitor negative control group were 0.45±0.15, 1.02±0.03, 2.28±0.03, 1.11±0.03, respectively (P<0.05). And its expression in the JEG3 cell line were 0.58±0.03, 1.25±0.15, 2.25±0.03, 1.21±0.03, respectively (P<0.05). (3) The results of western blot. ①The expression of MMP-2 protein in the placentas of mPE, sPE, normal pregnant women were 1.63±0.04, 0.55±0.03, 2.82±0.03, respectively (P<0.05). ②The expression of MMP-2 protein in the JAR cell line in the miR-106b mimics group, the mimics negative control group, the miR-106b inhibitor group and the inhibitor negative control group were 0.41±0.03, 0.97±0.03, 2.25±0.03, 1.01±0.03, respectively (P<0.05). And its expression in the JEG3 cell line were 0.53±0.03, 1.20±0.03, 2.31±0.04, 1.19±0.03, respectively (P<0.05). (4) miR-106b could inhibit the proliferation of JAR and JEG3 cells, cell proliferation rates in the miR-106b mimics group were lower than that in the mimics negative control group (P<0.05).

Abstract
Objective: To analyze the clinical features of Kleine-Levin syndrome (KLS) patients. Methods: Clinical data of 44 patients with KLS of the Sleep Center of Peking University People's Hospital from January 2002 to July 2013 were systematically reviewed. The predisposing factors and clinical presentations were summarized, and compared with the data from a Western KLS study with a large subjects number. Nocturnal polysomnography (PSG) and multiple sleep latency test (MSLT) were conducted during relapse and remission period, respectively. HLA-DQB1*0602 gene were screened and analyzed. Results: Among the 44 patients, 28(63.6%) were men and 16(36.4%) were women, with a mean age of (18.3±8.9) years old. Most patients developed the symptoms during adolescence. Infection or fever was the most common trigger for episode. The main clinical presentations were 44(100.0%) hypersomnia, 31(70.5%) forgetfulness, 26(59.1%) decreased appetites, 24(54.5%) juvenile behavior, 18(40.9%) depression, etc. Compared with the Western study, it showed that our patients had decreased instead of increased appetite. The PSG testing did not have remarkable findings. MSLT showed mean sleep latency was significantly shorter during relapse than during remission [(10.4±5.4) vs (15.3±3.4) min, P=0.009]. HLA-DQB1*0602 was positive in 12 of 40(30.0%) patients, which was similar to the data in the Chinese population. Conclusions: KLS has various clinical characteristics. The presentation of appetite may be different between Chinese and western KLS patients.

Abstract
Reproductive traits have long been studied and have an important influence on chicken breeding. To identify quantitative trait loci affecting reproductive traits, a genome-wide analysis of a Chinese chicken breed was performed to analyze age at first egg body weight at first egg, first egg weight, egg weight at the age of 300 days, egg weight at the age of 462 days, egg number at the age of 300 days, egg number between the ages of 300 and 462 days and egg number at the age of 462 days. Nineteen SNPs related to reproductive traits were presented (P < 1.80E-6). Nine of the 19 SNPs had a significant effect on BWF, six SNPs were significantly associated with egg weight, and four SNPs were significantly associated with egg number. These SNPs were located near to or in 17 genes including FAM184B, HTT, KCNH7, CDC42BPA, KCNIP4, GJA5, CBFB, and GPC6. The present results may be beneficial for reproductive research and may be used in marker-assisted selection in future studies. These results could potentially benefit further breeding programs, especially in Jinghai Yellow Chicken.

Abstract
To assess the efficacy and safety of the SGLT-2 inhibitors as adjunct therapy to insulin in T1DM, clinical trials indexed in PubMed, Cochrane Library, EMbase from inception through April 5, 2016. A meta-analysis was conducted on trials of SGLT-2 inhibitors in patients with T1DM on insulin therapy using RevMan 5.3 software. Of the 371 articles identified, ten met eligibility criteria. Seven clinical trials including four randomized controlled trials and 581 patients were included. Compared with the control group, SGLT-2 inhibitors group had significantly reduced fasting plasma glucose by 0.69 mmol/L [1.32; 0.07], glycosylated hemoglobin A1C by 0.37% [0.54; 0.20], body weight by 2.54 kg [3.48; 1.60] and total daily insulin dose by 6.22 IU [8.04; 4.40]. The total incidence of adverse events (AEs), hypoglycemia, and genital and urinary infections were also similar to placebo, while an increased incidence of diabetic ketoacidosis (DKA) (n = 16) was seen in SGLT-2 inhibitors group. The present study demonstrates that SGLT-2 inhibitors are effective as adjunct therapy to insulin in T1DM, heralding improved glycemic control, reduced body weight and total daily insulin dose without an increase in total AEs, hypoglycemia, or genital and urinary infections. However, the risk of DKA should be carefully monitored in future clinical trials.

Abstract
The process of molecular recognition is the assembly of two or more molecules through weak interactions. Information in the process of molecular recognition can be transmitted to us via physical signals, which may find applications in sensing and switching. The conventional signals are mainly limited to light signal. Here, we describe the recognition of diols with Cu(1,10-phenlothroline)2SeO4 and the transduction of discrete recognition events into dielectric and/or ferroelectric signals. We observe that systems of Cu(1,10-phenlothroline)2SeO4·(diol) exhibit significant dielectric and/or ferroelectric dependence on different diol molecules. The compounds including ethane-1,2-diol or propane-1,2-diol just show small temperature-dependent dielectric anomalies and no reversible polarization, while the compound including ethane-1,3-diol shows giant temperature-dependent dielectric anomalies as well as ferroelectric reversible spontaneous polarization. This finding shows that dielectricity and/or ferroelectricity has the potential to be used for signalling molecular recognition. Molecular recognition is an important biological process where guest and host molecules interact through non-covalent bonding. Ye et al. show that this can be sensed by the dielectric and ferroelectric signals of the final complexes in a series of metal-coordination compounds with different diol molecules.

Abstract
4,5-Bis(2-methyl-5-phenylthiophen-3-yl)-1,3-dithiol-2-one (L1o) was elaborately designed to afford dithienyl-dithiolene as a new photochromic ligand. We describe herein the preparation and characterization of unprecedented photochromic dithienyl-dithiolene complexes with cis-orientation of dithienylethene (DTE) stabilized by metal chelation instead of conventional cyclopentene. The treatment of L1o with sodium methoxide in methanol afforded a disodium salt of dithiolate dianion, which reacts with M(dppe)Cl2 (dppe = 1,2-bis(diphenylphosphino)ethane, M = Ni, Pd) to give neutral compounds M(dppe)(dithiolate) as established by X-ray crystallography. The reaction of L1o with NiCl2 in the presence of sodium methoxide allows the isolation of an anionic nickel(ii) bis(dithienyl-dithiolene) complex with photochemical inertness. In contrast, the corresponding reaction with ZnCl2 afforded a dianionic zinc(ii) complex chelated by two dianionic dithienyl-dithiolenes, which displays stepwise photocyclization upon irradiation with UV light at 312 nm as demonstrated experimentally and theoretically. Only when dithienyl-dithiolene behaves as a dicationic ligand instead of neutral or monoanionic species, it is possible to achieve reversible photochromism in the corresponding metal complexes.

Six mutations, which were not reported before, were c. 76-77delTT, c. 343-344delCA, c. 481A>T, c. 1152G>C, c. 1613G>A for CYBB gene, and c. 137T>G for NCF2 gene. Among CGD patients with CYBB mutation, SI of patients with gp91(+) was higher than patients with gp91(0) 14.6 vs. 2.5(t=44.21, P=0.004). Patients of NCF1 mutation had higher SI than patients with CYBB mutation, 17.7 vs. 2.5 (t=60.8, P=0.003). CONCLUSION Flow cytometric-DHR analysis and gp91 protein detection are important diagnostic methods for CGD, they could help the precise diagnosis of CGD.Different mutation types, different mutation genes could have impact on the results of respiratory burst and gp91 level.The application of diagnostic technology from function, protein to gene analysis could help precise diagnosis of CGD.

Abstract
Increasing evidence supports that acupuncture intervention is an effective approach for intraoperative and postoperative pain. Neuron-microglia crosstalk, mediated by the purinergic P2X7 receptor (R)/fractalkine/CX3CR1 cascade in the spinal cord dorsal horn, plays a pivotal role in pain processing. However, its involvement in the analgesic effect of electroacupuncture (EA) remains unclear. In this study, a rat neck-incision pain model was established by making a longitudinal incision along the midline of the neck and subsequent repeated mechanical stimulation. EA stimulation was applied to bilateral LI18, LI4-PC6, or ST36-GB34. The thermal pain threshold, cervicospinal ATP concentration, expression levels of purinergic P2XR and P2YR subunits mRNAs, and fractalkine, CX3CR1 and p38 MAPK proteins, were detected separately. The neck incision induced strong thermal hyperalgesia and upregulation of spinal ATP within 48 h. No significant change was found in thermal hyperalgesia after a single session of EA intervention. However, a single session of EA dramatically enhanced the neck incision-induced upregulation of ATP and upregulated the expression of P2X7R, which was reversed by two sessions of EA. Two sessions of EA at bilateral LI18 or LI4-PC6 attenuated hyperalgesia significantly, accompanied with downregulation of P2X7R/fractalkine/ CX3CR1 signaling after three sessions of EA. EA stimulation of LI18 or LI4-PC6 alleviates thermal hyperalgesia in neck-incision pain rats, which may be associated with its effects in regulating the neck incision-induced increase of ATP and P2X7R and subsequently suppressing fractalkine/CX3CR1 signaling in the cervical spinal cord.

Abstract
Biliary atresia (BA) is a destructive bile duct disease occurring in newborn children within a few weeks after birth. In this study, the effect of miR-29c and miR-129-5p on epithelial-mesenchymal transition (EMT) in experimental BA was explored by constructing BA mouse models via Rhesus rotavirus vaccine infection. miR-29c and miR-129-5p expression was analyzed by real-time quantitative polymerase chain reaction. EMT was established by induction with transforming growth factor (TGF)-β1. miR-29c and miR-129-5p were overexpressed and inhibited, respectively, by Lipofectamine transfection. EMT-related protein (formin-like 2, FMNL2; E-cadherin; vimentin; and cytokeratin-19, CK-19) expression was analyzed by western blot and immunofluorescent assay. The results indicated that miR-29c and miR-129-5p were downregulated and upregulated in BA mice. TGF-β1 induction caused a time-dependent decrease and increase in miR-29c and miR-129-5p, respectively. Additionally, TGF-β1 induced an increase in FMNL2 and vimentin expression and a decrease in E-cadherin and CK-19 expression (P < 0.05). Overexpression or suppression of miRNA-29c or miR-129-5p, respectively, induced the inhibition of FMNL2 and vimentin, and promotion of E-cadherin and CK-19 expression, in the test groups compared to the non-intervention group (P < 0.05). However, the FMNL2, vimentin, E-cadherin, and CK- 19 expression did not differ between the control and non-intervention groups (P > 0.05). Thus, miR-29c upregulation or miR-129-5p downregulation effectively prevented EMT in BA by regulating the expression of EMT pathway-related proteins. Therefore, miR-29c and miR-129-5p could be utilized as therapeutic targets for BA in the future.

Abstract
OBJECTIVE To evaluate the association of prostate volume, PSAD and F/T with prostate cancer detection rate in males with a total PSA of 4-10 μg/L. METHODS Clinical data of 196 patients who underwent prostate biopsy from November 2006 to September 2010 and with a PSA of 4-10 μg/L were retrospectively analyzed. The association of detection rate of prostate cancer with prostate volume, prostate specific antigen density PSAD) and free PSA/total PSA ratio (F/T) was analyzed by Spearman coefficient, receiver operating characteristic curve and logistic regression analysis. RESULTS The prostate volume, PSAD and F/T had a significant association with detection rate of prostate cancer (P<0.05 for all). The odd ratio was 0.96, 1.91 and 0.02, respectively. The area under curve (AUR) was 0.31, 0.66 and 0.63, respectively. The cancer detection rate was decreased along with the increase of prostate volume. When PSAD 0.15 ng·ml(-1)·ml(-1) was used as the cut-off value, the sensitivity, specificity, positive prediction rate and negative prediction rate was 72.3%, 51.1%, 42.3% and 21.2%, respectively. When the patients were divided by prostate volume into <19.9, 20-39.9, 40-59.9, 60-79.9 and >80 ml subgroups, the cancer detection rate of each subgroup was 50.0%, 45.6%, 30.8%, 15.4% and 5.6%, respectively. CONCLUSION In patients with a total PSA of 4-10 μg/L, the prostate cancer detection rate has a significant association with prostate volume, PSAD and F/T.

Abstract
The utilization of phosphorescent metal cluster complexes as new types of emitting materials in organic light-emitting diodes (OLEDs) is becoming an alternative and viable approach for achieving high-efficiency electroluminescence. We report herein the design of cationic PtAu2 cluster complexes with differently positioned 9-phenylcarbazole-acetylides to serve as phosphorescent emitters in OLEDs. The rigid structures of PtAu2 complexes cause intense phosphorescence with quantum yields of over 85%, which originates from (3)[π(phenylcarbazole-acetylide) → π*(dpmp)] ligand-to-ligand and (3)[π(phenylcarbazole-acetylide) → p/s(PtAu2)] ligand-to-metal charge-transfer triplet excited states. When 8 wt % PtAu2 is doped to blended host materials of TCTA and OXD-7 (2:1 weight ratio) as light-emitting layers, solution-processed OLEDs give a current efficiency of 78.2 cd A(-1) and an external quantum efficiency (EQE) of 21.5% at a practical luminance of 1029 cd m(-2) with a slow efficiency roll-off upon increasing luminance. This represents the best device performance and the highest efficiency recorded at practical luminance for solution-processed OLEDs.

Abstract
Severe fever with Thrombocytopenia Syndrome (SFTS) is an emerging hemorrhagic fever disease in the rural areas of east-central China, which is caused by SFTSV-a newly discovered bunyavirus. SFTSV is most likely transmitted by tick bites but can also be transmitted within human beings. The onset of SFTS is sudden and with rapid progress, with main clinical manifestations as fever, thrombocytopenia, leucopenia and gastrointestinal and hepatorenal dysfunctions. Some patients may die from multiple organ failure, and the case fatality rate is approximately 10%. In this paper, we use the method of literature review to summarize the recent research progress of SFTS which includes the epidemic distribution characteristics, medium of transmission, host animals, transmission routes and susceptibility in the general population.
