To evaluate the automated segmentation algorithm for detection of intra - retinal layers to process images obtained from ultra- high resolution optical coherence tomography ( OCT ) . Graph theory and the shortest path search based on dynamic programming were applied to automatically segment the 8 intra - retinal layers. We experimentally verified the accuracy and reliability of the algorithm. The results showed that the intra-retinal layer boundaries between automated and manual segmentations matched well. The algorithm successfully segmented the intra- retinal layers in glaucoma, high myopia, and retinitis pigmentosa patients. The proposed automatic segmentation for intra-retinal layers provides a promising tool for quantitative analysis in clinical diagnosis and treatment.

In clinic, some urinary protein makers can dynamically and noninvasively reflect the degree of renal tubular injury in patients with diabetic nephropathy (DN). These urinary biomarkers of tubular damage are broadly divided into two categories. One is newfound, including kidney injury molecule-1 (Kim-1), neutrophil getatinase-associated lipocalin (NGAL), liver-type fatty acid-binding protein (L-FABP) and cystatin C (CysC); the other one is classical, including beta2 microglobulin (beta2-MG), retinal binding protein (RBP) and N-acetyl-beta-D-glucosaminidase (NAG). It is reported that, the increases in urinary protein markers are not only closely related to the damage of tubular epithelial cells in DN patients, but also can be ameliorated by the treatment with Chinese herbal compound preparations or Chinese herbal medicine. Recently, although urinary proteomics are used in the protein separation and identification, the traditional associated detection of urinary protein markers is more practical in clinic. At present, it is possible that the associated detection of urinary biomarkers of glomerular and tubular damages may be a feasible measure to reveal the clinical significance of urinary protein markers in DN patients and the interventional effects of Chinese herbal medicine.

To analyze the characteristic of urinary protein spectrum in patients with stage III diabetic nephropathy (DN) and its compliance with traditional Chinese medicine (TCM)symptom, for the sake of providing a basis for clarifying the rules of TCM syndrome differentiation in DN. Adopting the traditional epidemiological retrospective method, thirty-eight TCM syndromes and urinary protein with medium or low molecular weight, as well as urinary enzyme, including 24 h urinary protein (Upro), urinary albumin( UAlb), urinary retinal binding protein( URBP), urinary cystatin C (UCysC), urinary N-acetyl-beta-D-glucosaminidase (UNAG), were collected from 108 patients with stage III DN, and a multiple factor regression analysis between them was conducted. As the results, the levels of Upro, UAlb, URBP, UCysC, and UNAG were increased in 108 patients with stage III DN. Qi-Yin deficiency type was the major type. The level of UAlb in patients with Qi-Yin deficiency type was significantly higher than those without Qi-Yin deficiency type (P < 0.05). The elevation of Upro with the factors as swift digestion with rapid hungering, lassitude and lack of strength, weakness of waist and knees was complied, the elevation of UA1b with the factors as dry mouth with desire to drink, the elevation of URBP with the factors as numbness of extremities, shortness of breath, the elevation of UCysC with the factors as clear urine in large amounts, and the elevation of UNAG with the factors as frequent micturition, were complied respectively. In conclusion, for 108 stage III DN patients. The increase in urinary protein spectrum including UAlb, URBP, UCysC, and UNAG is the major characteristic. Shen and Pi are the major organs related to the appearance of urinary protein; Pi-Shen deficiency is the basic pathogenesis. The level of UAlb is taken as one of the objective syndrome factors for Qi-Yin deficiency type. The levels of UNAG and UCysC are possibly the objective syndrome factors for Shen-Qi deficiency type.

OBJECTIVETo study the clinical features, therapeutic effects, survival time and prognostic factors of patents with mantle cell lymphoma (MCL).
METHODSClinical data of 47 MCL patients admitted from January 2002 to December 2011 were retrospectively analyzed.
RESULTSOf all patients, median age was 58 year-old and male to female ratio was 3.3:1. Forty-two cases (89.4%) were in Ann Arbor stage III-IV, 13 cases (27.7%) with bone marrow involvement, 6 cases (12.8%) with lymphocytosis, 18 cases (38.3%) with elevated LDH, and 28 cases (59.6%) with elevated β(2)-MG. Age, bone marrow involvement, increased LDH level and treatment without rituximab were poor prognostic factors. The efficiency and complete remission rate of rituximab combined with chemotherapy were 91.4% and 48.6%, which were superior to those of CHOP regimen (41.7% and 16.7%). As compared to CHOP regimen, rituximab combined with chemotherapy induced longer progression-free survival and overall survival.
CONCLUSIONMost patients with MCL were older adults with a male predominance and usually had bone marrow involvement and poor prognosis. Rituximab combined with chemotherapy could significantly improve patient outcome.

OBJECTIVE: To evaluate the pharmacological effects of Liangyuan Pipagao on cough reflex and ciliary action. Liangyuan Pipagao is a compound preparation of traditional Chinese medicine. METHODS: Cough was induced by aerosol citric acid in guinea pigs and aerosol capsacin in mice. Excretion function of the airway in mice was determined by phenol red method. Ciliary movement function of frog esophagus was examined by a migration method of charcoal granules. RESULTS: Liangyuan Pipagao inhibited both the citric acid-induced cough in guinea pigs and capsacin-induced cough in mice. ID(50)value 2.64 g/kg (95%Cl1.12 approximately 6.19) and 11.40 g/kg (95%Cl5.76 approximately 22.58) respectively. Further, Liangyuan Pipagao increased phenol red excretion in mice airways and stimulated ciliary action of frog esophagusin a dose-dependent fashion. ED(50) value 7.70 g/kg (95%Cl 4.62 approximately 12.83) and EC(25) value 1.07 X 10(-4) (95% Cl 0.394 approximately 2.92x10(-4)) respectively. CONCLUSION: Liangyuan Pipagao a traditional Chinese medicine may have anti-tussive as well as expectorant actions.

BACKGROUND: This meta-analysis aimed to determine whether extracorporeal cardiopulmonary resuscitation (ECPR), compared with conventional cardiopulmonary resuscitation (CCPR), improves outcomes in adult patients with cardiac arrest (CA). DATA RESOURCES: PubMed, EMBASE, Web of Science, and China Biological Medicine Database were searched for relevant articles. The baseline information and outcome data (survival, good neurological outcome at discharge, at 3–6 months, and at 1 year after CA) were collected and extracted by two authors. Pooled risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using Review Manager 5.3. RESULTS: In six studies 2260 patients were enrol ed to study the survival rate to discharge and long-term neurological outcome published since 2000. A significant effect of ECPR was observed on survival rate to discharge compared to CCPR in CA patients (RR 2.37, 95%CI 1.63–3.45, P<0.001), and patients who underwent ECPR had a better long-term neurological outcome than those who received CCPR (RR 2.79, 95%CI 1.96–3.97, P<0.001). In subgroup analysis, there was a significant difference in survival to discharge favoring ECPR over CCPR group in OHCA patients (RR 2.69, 95%CI 1.48–4.91, P=0.001). However, no significant difference was found in IHCA patients (RR 1.84, 95%CI 0.91–3.73, P=0.09). CONCLUSION: ECPR showed a beneficial effect on survival rate to discharge and long-term neurological outcome over CCPR in adult patients with CA.

Objective To investigate how the interactions between fat mass- and obesityassociated (FTO) gene rs9939609 variants and daily-life related behavioral factors would influence the risk of obesity among the Chinese school-aged children. Methods 3503 school-aged children were selected from the Beijing Child and Adolescent Metabolic Syndrome (BCAMS) Study, and divided into obese children (n=1229) and non-obese children (n=2274). Venipuncture blood test,genotyping and questionnaire were performed. Results Five common factors including protein foods, tobacco & alcohol, vegetables & fruits, sedentary behavior and physical exercise in spare time were extracted with factor analysis methodology. Data from logistic regression analysis showed that taking the interaction of rs9939609 variant with protein foods as an example, the risk of interaction accounted for 19.16% when both factors existing simultaneously. Similarly, the interactions of this SNP with vegetables & fruits, sedentary behavior and physical exercise in spare time appeared to be 5.97%, 19.62% and 12.43% respectively; however there might not be interaction between tobacco,alcohol and the SNP in the Chinese children. Conclusion Protein foods, vegetables & fruits,sedentary behavior and physical exercise might modify the effects of FTO rs9939609 variant on the risk of obesity in Chinese school-aged children. However, large-scale, prospective studies with detailed information on related behavioral factors would be ideal models for identifying the interactions between genes and environment.
