The article analyzed the contemporary study of pattern recognition of tongue images in traditional Chinese medicine by computer technology from its key sectors. It regards that the methods of orthogonal design and evaluation of image quality should be introduced to get a high-quality and practicable condition. In the field of tongue image segmentation, multiple methods used together are expected to improve the effect of segmentation. A scientific and canonical standard of tongue diagnosis based on comprehensive experts' experience with Delphi evaluation method and multi-center experts diagnosis on internet are also very essential. The study of pattern recognition on tongue image is still concentrated on the color. Further study should be extended to achieve quantification. And a comprehensive diagnosis on pattern recognition of tongue image is the aim that should be focused on later.

Objective To investigate the expression levels and clinical significance of programmed cell death 1 ligand (PD-L1) and programmed cell death factor-1 (PD-1) in peripheral T-cell lymphoma (PTCL). Methods Immunohistochem?istry was used to detect expression levels of PD-L1 and PD-1 in PTCL (test group, n=51) and benign proliferative lesions of lymph node tissues (control group, n=20). The correlations of PD-L1 and PD-1 expressions with clinical pathological param?eters and prognosis were analyzed between two groups. Results The expression level of PD-L1 was significantly higher in PTCL group than that in control group (74.51%vs 35.00%,χ2=9.662, P<0.05). The positive expression of PD-1 was signifi?cantly higher in PTCL group than that in control group (66.67%vs 25.00%,χ2=10.074, P<0.05). There were significant dif?ferences in PD-L1 and PD-1 expressions between different peripheral lactate dehydrogenase (LDH) levels of PTCL group (P<0.05). After two cycles of CHOP or ECHOP treatments, the response rate (RR) was higher in PD-L1 negative group than that in positive group (84.6%vs 47.4%,χ2=5.478, P<0.05), and RR was higher in PD-1 negative group than that in positive group(82.4%vs 44.1%,χ2=6.755, P<0.05). The median overall survival (OS) time was higher in PD-L1 negative group than that in positive group (29.8 months vs 17.6 months,χ2=4.413, P<0.05) and the median OS time was higher in PD-1 negative group than that in positive group (29.8 months vs 17.6 months,χ2=8.293, P<0.05). Conclusion There are high expression levels of PD-L1 and PD-1 in peripheral T-cell lymphoma, which is closely related with the elevated LDH in peripheral blood, poor response rate and shorter OS. Therefore, the expression levels of PD-L1 and PD-1 can be used as factors of worse effect of chemotherapy and poor prognosis.

Spinal cord injury can lead to neurogenic bowel dysfunction. With the research of the enteric nervous system, slow transit constipation had a better understanding of the pathogenesis. This article reviewed gastrointestinal motility after spinal cord injury and motilin, substance P, and vasoactive intestinal peptide.

OBJECTIVETo evaluate the clinical efficacy of manipulative reduction combined with percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) in treating osteoporotic vertebral compression fracture (OVCF) using meta-analysis method, in order to provide a reference for clinical treatment.

METHODSA systematic computer-based search (from January 1987 to April 2014) from CNKI, Wanfang database, Web of Science and PubMed were performed for the collection of controlled clinical researches on manipulative reduction combined with PVP or PKP in treating OVCF. The quality of selected researches was evaluated. Meta-analysis was adopted to evaluate visual analog scale, Cobb angle, anterior height ratio of the injured vertebra.

RESULTSA total of 7 researches of 410 patients were included in the present analysis, there were 5 RCTs and 2 non-RCTs and all come from China. Manipulative reduction combined with PVP could got better improvement in Cobb angle (WMD=-7.35; 95%CI: -12.15, -2.54) and anterior height ratio of the injured vertebra (P<0.01) than simple PVP, but no significant difference was found in improvement of visual analog scale (WMD=-0.01; 95%CI: -0.45, 0.42). There were no significant differences in the improvement of visual analog scale, Cobb angle, anterior height ratio of the injured vertebra between manipulative reduction combined with PKP and simple PKP (P>0.05).

CONCLUSIONCompared with simple PVP, manipulative reduction combined with PVP may result in more clinical efficacy on the improvement of Cobb angle and anterior ratio of the injured vertebra. And compared with simple PKP, manipulative reduction combined with PKP has no obvious advantages on the improvement of visual analog scale, Cobb angle, anterior height ratio of the injured vertebra. However, the number and quality of the literatures, may resulted in the effect of mistrust, so more large sample and high-quality RCTs are needed in future.

Objective To investigate the multiple factors correlated to femoral head necrosis in patients over 45 years old with femoral neck fractures after closed reduction and cannulated screws fixation.Methods Three hundred patients with femoral neck fracture were admitted from May 1999 to May 2004 and treated by closed reduction and internal fixation with cannulated screws.We analyzed the multiple factors:age,gender,Garden classification,follow-up time,procedure delay,quality of reduction,time of full-weight-loading,fixation removal, and preoperative traction.Multiple correlation factors were analyzed by SPSS10.0 statistic system.Results Complete case records were documented in 99 cases who were followed up for an average of 24.5 months(range,8 to 60 months).Femoral head necrosis occurred in 15 cases(15.2%).Time of femoral head necrosis was 8 to 50 months after operation.The combination of quality of reduction,preoperative traction,age,and age?fixation re- moval was found to have the most significant influence on femoral head necrosis after internal fixation for femoral neck fractures.Conclusions Good reduction is the most important factor correlated to the outcome of a femoral neck fracture.Age is linked to the risk of necrosis but it is relatively insignificant.Preoperative traction in wrong positions can increase the incidence of necrosis.Garden classification is important in predicting femoral head necrosis and is associated with quality of reduction,but it is not a risk one in the combination of multiple correlation factors that lead to the necrosis.
