Objective:To investigate the correlation of sleep disorders(SD)with serum levels of amyloid β-proteins(Aβ 1-42)and tau phosphorylated at threonine(P-Tau 181)in patients with Alzheimer's disease(AD). Methods:A total of 126 patients with mild and moderate AD who met the inclusion criteria in the memory clinic, sleep clinic and geriatrics department of Jianghan Oilfield General Hospital affiliated to Yangtze University from February 2017 to January 2020 were included.The Pittsburgh Sleep Quality Index(PSQI)was used to evaluate sleep quality.Patients with PSQI scores ≥7 were included in the AD group with sleep disorders(AD-SD group), and patients with PSQI scores <7 were included in the AD group without sleep disorders(AD-NSD group). The Montreal Cognitive Assessment(MoCA), Global Deterioration Scale(GDS), Clinical Dementia Rating(CDR), Hamilton Rating Scale for Depression(HRSD)and Hamilton Anxiety Rating Scale(HAM-A)were used to evaluate cognitive and psychosocial symptoms.During the same time, biological markers such as serum Aβ 1-42, Aβ 1-40 and P-Tau 181 were detected by using enzyme-linked immunosorbent assays.Patients in the two groups received donepezil as an anti-dementia therapy, while the AD-SD group was treated additionally with a targeted sleep intervention.All patients underwent neuropsychological assessment and biochemical tests at enrollment and at the end of the 6th month, and results from all parameters at baseline and at the end of the 6th month were compared.At the end of the six-month treatment, patients in the AD-SD group were further divided into the recovery AD-SD sub-group and the no-recovery AD-SD sub-group based on the extent of sleep improvement. Results:Of the 126 AD patients, 93(73.8%)had sleep disorders.There was no statistically significant difference between the two groups in gender, age, onset age, educational level, course of disease, CDR, GDS, MoCA, Aβ 1-40 or Aβ 1-42/Aβ 1-40(all P>0.05). The scores of PSQI, HRSD and HAM-A and serum levels of Aβ 1-42 and p-Tau 181 showed statistically significant differences between the AD-ND and AD-NSD groups( P<0.05 or P<0.01). At the end of the 6th month, the scores of PSQI, GDS, HRSD and HAM-A and levels of Aβ 1-42, Aβ 1-40, and P-Tau 181 also showed statistically significant differences between the AD-ND and AD-NSD groups( P<0.05 or P<0.01). There was no statistically significant difference in results from other parameters( P>0.05). Spearman correlation analysis showed that PSQI was correlated with HRSD( r=0.271, P=0.009), HAM-A( r=0.479, P=0.000), Aβ 1-42( r=0.470, P=0.000), Aβ 1-42/ Aβ 1-40( r=0.479, P=0.000)and P-Tau 181( r=0.371, P=0.000)in the AD-SD group at baseline.Multivariate Logistic regression model showed that serum Aβ 1-42 and P-Tau 181 levels and HRSD had predictive effects on changes in sleep quality in AD patients( OR=1.897, 1.269 and 1.889, P=0.000, 0.003 and 0.000). The areas under the receiver operating characteristic(ROC)curves for Aβ 1-42, P-Tau 181 and HRSD were 0.926(95% CI: 0.860-0.991), 0.837(95% CI: 0.746-0.927)and 0.854(95% CI: 0.776-0.932), respectively. Conclusions:Sleep quality is correlated with serum Aβ 1-42and P-Tau 181 levels in AD patients.Elevated serum levels of Aβ 1-42 and P-Tau 181 and high HRSD scores are important predictors of SD in AD patients and may be used as indexes for clinical treatment efficacy.

Chronic high-salt diet-associated renal injury is a key risk factor for the development of hypertension. However, the mechanism by which salt triggers kidney damage is poorly understood. Our study investigated how high salt (HS) intake triggers early renal injury by considering the ‘gut-kidney axis’. We fed mice 2% NaCl in drinking water continuously for 8 weeks to induce early renal injury. We found that the ‘quantitative’ and ‘qualitative’ levels of the intestinal microflora were significantly altered after chronic HS feeding, which indicated the occurrence of enteric dysbiosis. In addition, intestinal immunological gene expression was impaired in mice with HS intake. Gut permeability elevation and enteric bacterial translocation into the kidney were detected after chronic HS feeding. Gut bacteria depletion by non-absorbable antibiotic administration restored HS loading-induced gut leakiness, renal injury and systolic blood pressure elevation. The fecal microbiota from mice fed chronic HS could independently cause gut leakiness and renal injury. Our current work provides a novel insight into the mechanism of HS-induced renal injury by investigating the role of the intestine with enteric bacteria and gut permeability and clearly illustrates that chronic HS loading elicited renal injury and dysfunction that was dependent on the intestine.

Objective To analyze the clinical factors for pathologic complete response ( pCR) after preoperative neoadjuvant chemoradiotherapy ( neo?CRT) for locally advanced rectal cancer. Methods From 2005 to 2012, 297 patients with locally advanced rectal cancer and complete clinical data were enrolled as subjects. Those patients were diagnosed with biopsy and treated with neo?CRT ( radiotherapy by 3?dimonsional conformal radiotherapy or volumetric?modulated arc therapy) followed by radical surgery. The logistic regression model was used for the multivariate analyses of the correlation of pCR with age, gender, distance between tumor and the anal verge, serum level of carcinoembryonic antigen ( CEA ) before treatment, hemoglobin level before treatment, cT staging, and cN staging. Results In all patients, 78 ( 26?7%) patients had pCR after treatment. The numbers of patients with pCR were 42( 34?4%) in patients with stage T1?T3 disease and 37(21?1%) in patients with stage T4 disease. In the patients with serum CEA levels no higher than 5?33 ng/ml, 55(36?4%) had pCR after treatment, while in the patients with serum CEA levels higher than 5?33 ng/ml, only 24( 16?4%) had pCR. The univariate analysis revealed that age, gender, distance between tumor and the anal verge, anemia before treatment, or cN staging were not related to pCR. The multivariate analysis showed that stage cT1?T3 and a serum CEA level no higher than 5?33 ng/ml before treatment were influencing factors for pCR after neo?CRT for locally advanced rectal cancer ( P=0?031,P=0?000) . Conclusions The clinical staging and the serum CEA level before treatment are influencing factors for pCR after neo?CRT for locally advanced rectal cancer. The serum CEA level before treatment can be considered as a predictor of pCR after neo?CRT for locally advanced rectal cancer.

BACKGROUND:The obesity has led to a plenty of diseases including hypertension, coronary heart disease, fatty liver, hyperlipidemia, and type 2 diabetes. Therefore, understanding the mechanism of adipocyte differentiation is of far-reaching significance to the prevention and treatment of obesity. For the current studies of the mechanism of adipocyte differentiation pay more attention to microRNA, rather than long non-coding RNAs (lncRNAs). OBJECTIVE:To obtain the lncRNAs whose fold change was apparent during adipogenic differentiation, and to further screen the lncRNAs that possibly play a crucial role in adipogenic differentiation for verification. METHODS:Subcutaneous fat was obtained from human abdomen. Adipose-derived stem cells were col ected using tissue culture method. The third passage of adipose-derived stem cells was used for adipogenic differentiation. Through microarray technology, the expression levels of lncRNAs and mRNA were analyzed at 0, 5 and 12 days in adipogenic differentiation. Combining with bioinformatics report, lncRNAs apparently presented fold change were screened and verified by qRT-PCR. RESULTS AND CONCLUSION:Fold change 1.5 (P<0.05) was considered as a criterion during adipogenic differentiation. The number of up-regulated lncRNAs was 748 for 5 days versus 0 day, 847 for 12 days versus 0 days, 593 for 12 days versus 5 days. At the same time, the down-regulated number was 828 for 5 days versus 0 day, 1 113 for 12 days versus 0 day, 750 for 12 days versus 5 days during adipogenic differentiation. In combination with bioinformatics analysis results, 3 of 28 lncRNAs were related to lipid metabolism:AK304548, BP216319 and DA852857, according to the standard that fold change in 0, 5 and 12 days was higher, and the target genes were known to be associated with adipogenesis-related genes. PCR results showed that the expression of AK304548 and BP216319 and its target gene presented an up-down trend, which is consistent with the microarray sequencing results. These results indicated that lncRNA plays a critical regulatory role in the adipogenic differentiation.

OBJECTIVETo construct eukaryotic expression vectors for different domains (V and VC1) of the extracellular region of the receptor of advanced glycation end products (RAGE) and investigate the roles of these domains in prostate cancer.

METHODSThe coding sequence of V and VC1 domains was amplified from the plasmid pcDNA3-HA-RAGE by PCR and cloned into the pcDNA3-HA vector following routine procedures. After identification by PCR and sequencing, the vectors including V and VC1 domains were transfected into PC-3 cells. Western blotting and immunofluorescence were used to detect the expression and distribution of the expressed products in transfected PC-3 cells.

RESULTSThe expression vectors containing V and VC1 domains of RAGE were successfully constructed as confirmed by PCR and DNA sequence analysis. The V and VC1 domains of RAGE were highly expressed and showed a cytoplasmic distribution in transfected PC-3 cells.

CONCLUSIONThe constructed eukaryotic expression vectors for V and VC1 domains of RAGE can be efficiently expressed in prostate cancer cells.
