Objective To study the bone turnover and its related molecular mechanism in STZ-induced diabetic rats. Methods Of 30 male SD rats studied, 15 were induced diabetics by intravenous injection of streptozotocin (50 mg/kg)and fed for 8 weeks. After the sacrifice of both the diabetic and control groups, serum Ca, P, alkaline phosphatase (ALP), and osteocalcin were determined, and 24 h urinary Ca and urinary cross-linked N-telopeptide of type Ⅰ collagen (NTx)and creatinine (Cr)ratio were also determined. The left tibia was dissected for bone histomorphometry analysis. Right femur and lumbar vertebrae (L1-L4) were reserved for bone mineral density (BMD) determination. The right tibia was separated for the study of bone tissue RANKL/osteoprotegerin, Core binding factor 1 (Cbfa1) ,osterix and osteocalcin mRNA level which was performed by real-time quantitative reverse transcription polymerase chain reaction assay. Results No significant difference was found in serum Ca, P, and ALP levels between 2 groups of rats. ST-Z-induced diabetic rats were characterized by extreme hyperglycemia, marked weight loss, polyuria, and hypercalciuria. A low-turnover osteopenia was evidenced in diabetic rats by decreased BMD in both femur [(0. 099±0.013) vs (0. 139 ± 0.013 g/cm~3) , P < 0.01] and lumbar vertebrae [(0. 107±0.011)vs (0. 149±0.009) g/cm~3, P<0.01] , reduced serum osteoealcin level [a marker of formation, (3.03±0.52) vs (6. 18±0.71) ng/ml ,P<0. 01]) ,decreased urine NTx/Cr ratio [(5. 67±0.86) vs (5.23±0.98) nmol/g Cr, P<0. 05], decreased trabeeular volume and thickness, and reduced bone label surface and bone formation rate [(0. 44±0. 11) vs (0. 78±0. 14) μm/d,P<0. 01] by bone dynamic study. The RANKL/ osteoprotegerin [(0.57±0.11)vs (0.89±0.13) ,P<0.01] ,osterix [(1.93×10~(-4)±0.65×10(~-4))vs (4.19×10~(-4)± 0.71×10~(-4)) ,P<0.01] ,Cbfa1 [(26.68×10~(-4)±6.53×10~(-4))vs (37.21×10~(-4)±7.14×10~(-4)) ,P<0.01] ,and osteocalcin [(2.25×10~(-4)±1.19×10~(-4))vs (3.43×10~(-4)±1.63×10~(-4)) ,P<0.01] mRNA expressions were declined in the bone tissue of the tibia in the ST-Z-induced diabetic rats, as compared with the control. Conclusion A low-turnover osteopenia is evidenced in STZ-induced diabetic rats by significant decrease of both osteoclastic marker(RANKL/ osteoprotegerin)and osteoblastic marker (osterix ,Cbfa1 ,osteocalcin)mRNA levels in tibia.

This study aimed to analyze the etiology of the encephalitis outbreak in Longyan, Fujian Province, China in 2010, in order to provide valuable information for this prevention and control of this disease. Pathogens were confirmed from cerebrospinal fluid samples with fluorescent RT-PCR, virus isolation (RD cells), and neutralization tests. Then, the VP1 fragments or whole genome nucleotide sequences were determined for four virus strains using PCR. Homology was assessed using the MegAlign software, and a phylogenetic evolutionary tree was drawn using Mega 4.0 software. The results confirmed that the etiology of the outbreak was the ECHO6 intestinal virus, and the nucleotide sequence of the VP1 segment indicated that the C2 subtype was responsible. The genome sequence consisted of 7407 nucleotides, and resembled the genome of other ECHO and CoxB viruses with homology levels of 78.5%-87.3%. The encephalitis outbreak in Longyan in 2010 was caused by the ECHO6 C2 subtype intestinal virus, and its complete genome sequence length is similar to the standard strain (U16283) with a sequence homology of 80.4%.

Objective To explore the prognostic value and immune infiltration landscape of anoikis-related long noncoding RNAs (arlncRNAs) in lung adenocarcinoma. Methods RNA-seq and clinical data of lung adenocarcinoma were downloaded from the TCGA database, and anoikis-related genes were obtained from the GeneCards and Harmonizome databases. Coexpression, differential, and WGCNA analyses were performed to screen differentially expressed arlncRNAs closely related to the occurrence of lung adenocarcinoma. A prognostic risk model was then constructed based on the arlncRNAs, and its predictive efficacy was further validated. Finally, consensus clustering was used to identify the molecular subtypes associated with anoikis in lung adenocarcinoma. Results Seven prognostic arlncRNAs were identified, and the prognostic risk models established based on them had AUC values of ROC curves greater than 0.7. Survival and immune infiltration analyses revealed that low-risk patients had high overall survival and immune infiltration, implying that they experienced good immune treatment effects. Drug sensitivity analysis showed that the high-risk patients were more sensitive to commonly used chemotherapeutic agents than the low-risk patients. According to the expression of model genes, subtypes C1 and C2 were identified through consensus clustering, and C1 showed a good prognosis. Conclusion The prognostic risk model based on the seven arlncRNAs can effectively predict the prognosis of lung adenocarcinoma patients. The results of immune-related and drug sensitivity analyses provide a reference for the precise individualized treatment of patients with lung adenocarcinoma.

OBJECTIVETo establish a rapid, sensitive and efficient detection method for tobacco mosaic virus (TMV), and provide technical support of TMV detection of Rehmannia glutinosa f. hueichingensis. The virus-free plantlets could be produced on a large scale to ameliorate breed degeneration caused by viral disease.

Objective To analyse the prognosis of 117 newly diagnosed nasopharyngeal carcinoma (NPC) patients underwent intensity modulated radiotherapy (IMRT). Methods From Jan to Nov 2005, 117 NPC patients who were treated by IMRT were enrolled. There were 81 males and 36 females with a median age of 42 years (range 18-76 years). According to Chinese Fuzhou Staging system(1992), 11 cases were Stage I , 15 Stage Ⅱ, 54 Stage Ⅲ and 37 Stage ⅣA. IMRT was carried out with Peacock plan. The prescription dose to the gross target volume(GTVnx) of nasopharyngeal tumor was 68 Gy, that of positive neck lymph nodes (GTVnd) was 60-66 Gy, clinical target volume 1 (CTV1) was 60 Gy, and CTV2 was 54 Gy. Results After a median follow-up time of 48 months (range 10.5-59.5 months), the 3-and 5-year overall survival (OS) rates were 95.7 % and 89.7 %, the disease-free survival (DFS) rates were 91.5 % and 87.2%, and the local-regional control rates were 94.0 % and 91.5 %. Univariate analysis showed the KPS, stage, Fuzhou clinical stage, status of blood platelet before treatment and uric acid after treatment were correlated with OS rate. T stage was the only independent factor of prognosis in the COX stepwise regression model. Conclusion Radical IMRT significantly prolongs the survival of NPC patients. T stage is the only independent prognostic factor for NPC patients.

Objective To explore the determinants of Alzheimer' s disease (AD) patients with depression.Methods The degree of depression on AD patients was assessed by the geriatric depression scale.Improved cumulative logistic regression (ICLR) was used to analyze the determinants of AD patients with depression.Results 196 AD patients were investigated.Among the 196 AD patients,there were 60(30.6％ ) males and 136(69.4％ ) females,at 58-89 years of age (72.3 ± 6.0).Physical activity,diabetes,MoCA,hearing,economic sources and alcohol were related to the degree of depression of AD patients (P＜0.10 ).The difference between “normal” and “mild depression” was smaller than difference between “mild depression” and “severe depression”.Conclusion AD patients with mild depression were the target population for prevention and they were influenced by several factors listed above.
