Total 306 patients with early stage diabetes were enrolled in the study, after follow-up for 67 ± 8 months, the data of 288 cases were analyzed with survival analysis method. At the end of study 64 out 288 patients had high serum uric acid and the remaining 224 had normal uric acid levels. The prevalence of dominant proteinuria and reduced GFR were significantly higher in patients with high serum uric acid than those with normal serum uric acid (47. 36% vs 30. 29% and 66. 14% vs 37.72%, respectively, both P <0. 05). The results suggest that high level of serum uric acid is a risk factor for the progress of diabetic nephropathy.

Objective To explore the early diagnosis and risk factors for judging prognosis of acute respiratory distress syndrome (ARDS),and to provide references for clinical intervention.Methods Using the method for prospective cohort study,clinical data were collected from 64 ARDS and 66 high-risk ARDS patients in Department of Respiratory Diseases of Xinqiao Hospital from January 2013 to March 2016.They included patients' demographic data,Acute Physiology and Chronic Health Evaluation system Ⅱ (APACHE Ⅱ) score,oxygenation index,blood routine test,coagulation function and inflammatory markers (procalcitonin,C-reaction protein,tumor necrosis factor and interleukin-6) within 24h and the state of survival or death of the 24th day.Risk factors for predicting progression of the high-risk ARDS patients into ARDS patients and influencing the prognosis of the ARDS patients were analyzed by using logistic regression.Results Univariate logistic regression analysis found that the independent risk factors for progression of ARDS were APACHE Ⅱ score (OR=6.764,P=0.001),hypoproteinemia (OR=10.54,P=0.002),white blood cell count (OR=3.912,P=0.012),fibrinogen (OR=9.953,P=0.064),and D-dimer (OR=4.239,P=0.029).The mortality rate was 43.75％ (36/64) in ARDS group,and the oxygenation index (OR=6.573,P=0.014),platelet count (OR=9.376,P=0.003),hypoproteinemia (OR=10.738,P=0.056) were the independent risk factors of death in ARDS patients.Multivariate logistic regression showed that combination of multiple indicators for predicting ARDS improved the specificity,but reduce the sensitivity.APACHE Ⅱ and hypoproteinemia (sensitivity 62.50％,specificity 92.42％) and APACHE Ⅱ and D dimmer (sensitivity 62.07％,specificity 93.33％) had better specificity and sensitivity.The specificity and sensitivity of combining hypoproteinemia and platelet count to predict the risk of death in these patients were 77.78％ and 60.71％.Conclusions In high-risk ARDS patients,combining hypoproteinemia or APACHE Ⅱ score with D-dimer to judge the development of ARDS has good specificity but poor sensitivity.For ARDS patients,low oxygenation index,thrombocytopenia and hypoproteinemia indicate a poor prognosis.

Objective To investigate the association of estrogen receptor-? (ER-?) and vitamin D receptor (VDR) gene polymorphisms with peak bone mass in Shanghai women. Methods The ER-? PvuⅡ and XbaⅠ genotypes and VDR ApaⅠ genotypes were determined by PCR-RFLP in 515 unrelated healthy women aged 19-40 years of Han nationality in Shanghai. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry. Results Frequencies of ER-? PvuⅡ genotype PP, Pp and pp were 13.2%, 49.3% and 37.5% respectively. Frequencies of ER-? XbaⅠ genotype XX, Xx and xx were 4.7%, 40.4% and 54.9% respectively. Frequencies of VDR ApaⅠ genotype AA, Aa and aa were 5.8%, 41.9% and 52.3% respectively. Hardy-Weinberg equilibrium was evident for both ER-? and VDR gene polymorphisms. No association was found between ER-? PvuⅡ and XbaⅠ genotypes and BMD of various sites in women. Only a significant association was found between VDR ApaⅠ genotype and BMD at L 1-4(P

Melting temperature shift (T(m)-shift) is a new detection method that analyze the melting curve on real-time PCR thermocycler using SYBR Green I fluorescent dye. To establish a T(m)-shift method for the detection of Ancylostoma ceylanicum and A. tubaeforme in cats, specific primers, with GC tail of unequal length attached to their 5′ end, were designed based on 2 SNP loci (ITS101 and ITS296) of the internal transcribed spacer 1 (ITS1) sequences. The standard curve of T(m)-shift was established using the standard plasmids of A. ceylanicum (AceP) and A. tubaeforme (AtuP). The T(m)-shift method stability, sensitivity, and accuracy were tested with reference to the standard curve, and clinical fecal samples were also examined. The results demonstrated that the 2 sets of primers based on the 2 SNPs could accurately distinguish between A. ceylanicum and A. tubaeforme. The coefficient of variation (CV) of T(m)-values of AceP and AtuP was 0.07% and 0.06% in ITS101 and was 0.06% and 0.08% in ITS296, respectively. The minimum detectable DNA concentration was 5.22×10⁻⁶ and 5.28×10⁻⁶ ng/μl samples of AceP and AtuP, respectively. The accuracy of T(m)-shift method reached 100% based on examination of 10 hookworm DNA samples with known species. In the clinical detection of hookworm in 69 stray cat fecal sample, the T(m)-shift detection results were consistent with the microscopic examination and successfully differentiated between the 2-hookworm species. In conclusion, the developed method is a rapid, sensitive and accurate technique and can provide a promising tool for clinical detection and epidemiological investigation of cat-derived hookworms.

Echinostoma revolutum is a zoonotic food-borne intestinal trematode that can cause intestinal bleeding, enteritis, and diarrhea in human and birds. To identify a suspected E. revolutum trematode from a red-crowned crane (Grus japonensis) and to reveal the genetic characteristics of its mitochondrial (mt) genome, the internal transcribed spacer (ITS) and complete mt genome sequence of this trematode were amplified. The results identified the trematode as E. revolutum. Its entire mt genome sequence was 15,714 bp in length, including 12 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and one non-coding region (NCR), with 61.73% A+T base content and a significant AT preference. The length of the 22 tRNA genes ranged from 59 bp to 70 bp, and their secondary structure showed the typical cloverleaf and D-loop structure. The length of the large subunit of rRNA (rrnL) and the small subunit of rRNA (rrnS) gene was 1,011 bp and 742 bp, respectively. Phylogenetic trees showed that E. revolutum and E. miyagawai clustered together, belonging to Echinostomatidae with Hypoderaeum conoideum. This study may enrich the mitochondrial gene database of Echinostoma trematodes and provide valuable data for studying the molecular identification and phylogeny of some digenean trematodes.

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.
