Decorin is a member of small leucine - rich proteoglycan( SLRP) family. Decorin plays an important role in proliferation, differentiation, and migration of carcinoma cells by regulating virous signaling pathways. Decorin will be a novel target for cancer therapy for its role such as regulating cytokines, immunosupression,and inhibiting cancer cells growth and metastasis.

Objective To understand the status quo and influencing factors of behavior problems in rural left-behind children. Methods Cross-sectional sampling approach was used for this comparative study.A total of 983 children of 7 to 9 grades from three counties of Changzhi City finished out questionnaires. Results The prevalence of behavior problems was significantly increased in the left-behind children in comparison with the non-left-behind children (59. 7% vs 50. 0% ; χ2 =5. 591 ,P＜0. 05). Long-time separation with mother and poorer education level were risk factors of behavior problems of left-behind children. Conclusion Behavior problems in rural left-behind children are even serious. Parents should avoid becoming a long-term migrant employee and have more concerns to children's mental and behavior health.

Hemophagocytic lymphohistiocytosis(HLH), also known as hemophagocytic syndrome(HPS), is a hyperinflammatory syndrome caused by multiple etiologies.Interferon-γ(IFN-γ)has been reported to play a key role in the pathogenesis of HLH, and antibody against IFN-γ(emapalumab)can be used to treat HLH.Here, the findings on the role of IFN-γ in pathogenesis and emapalumab in treatment of HLH are reviewed respectively.

Objective Analysis of nitroglycerin combined with predictive nursing in the clinical application of coronary heart disease patients. Methods From January 2015 to December 2016, 200 patients with coronary heart disease were treated with angina pectoris. The patients were randomly divided into observation group and control group (100 cases). The control group was treated with routine nursing mode, and the patients in the observation group were treated with predictive nursing mode. The differences of hospitalization time and quality of life scores between the two groups were observed. The anxiety and depression of the two groups were observed before and after treatment, and the satisfaction of the two groups was observed. Results The scores of hospitalization and quality of life in observation group were better than those in control group (P<0.05). There was no statistically significant difference between SAS score and SDS score before treatment, but SAS score and SDS score of observation group were significantly lower than those of control group (P<0.05). The satisfaction degree of the patients in the observation group was better than that in the control group (P<0.05). Conclusion Predictive nursing has a good effect in the clinical nursing of patients with coronary heart disease and angina pectoris. It can effectively improve the patients' anxiety and depression, shorten the hospital stay and improve the quality of life. It is worth to be used in clinical practice.

OBJECTIVETo study the influence of nasolabial angle alteration on facial profile attractiveness and investigate the perception differences in profile attractiveness among laypeople.

METHODSA young Chinese female with normal hard and soft tissue cephalometric values was chosen as a research object. Profile photograph was taken in a natural head position. Photoshop software was chosen to rotate the nose tip and upper lip, thus changing the degree and direction of nasolabial angle. A total of 33 different profile pictures were achieved. Thirty-three professional orthodontists and 64 non-professionals were chosen to score these 33 pictures.

RESULTSWhen the upper lip position was fixed, the profile was considerably attractive because the angle of nasal tip was not changed or altered. When the nasal tip rotation angle was fixed, profiles with a retroclined upper lip were considered significantly attractive by the layperson and professional groups. Regardless of the direction of the nasal tip rotation, the respondents considered the profile with a retroclined upper lip highly attractive.

CONCLUSIONThe soft tissue profile with a retroclined upper lip looks considerably attractive in Chinese female populations. Therefore, during an orthodontic treatment, appropriate retraction of the incisor is recommended to improve soft tissue profile attractiveness.

Objective To evaluate the clinical efficacy of hypocaloric enteral nutrition in patients with acute severe traumatic brain injury (TBI).Methods A total of 100 patients with severe TBI [Glasgow Coma Scale (GCS) 3-8 points] were enrolled and randomly divided into hypocaloric enteral nutrition group (hypocaloric group, 41.86-62.79 kJ · kg-1 · d-1) and traditional caloric enteral nutrition group (traditional caloric group, 104.65-125.58 kJ · kg-1 · d-1) ,50 patients per group.The enteral nutrition was given at 24-72 hours postoperatively.The changes of total serum protein (TP), serum-albumin (ALB), plasma hemoglobin (Hb), fasting blood glucose (Glu) and major gastrointestinal tract complications were observed and compared at 7 and 14 days after enteral nutrition support.Results Levels of TP, ALB and Hb were lowered in both groups at 7 and 14 days after nutritional support but showed no statistical difference (P ＞ 0.05).Glu was (6.37 ± 1.02) mmol/L in hypocaloric calorie group, significantly lower than (7.35 ± 1.70) mmol/L in traditional caloric group at day 7 after nutritional support (P ＜ 0.05).At 7 and 14 days after nutrition support, nausea, regurgitation, vomiting and complication incidence showed no significant difference between hypocaloric calorie group and traditional caloric group after nutritional support (P ＞ 0.05), but abdominal distension, diarrhea and stomach retention rate in hypocaloric group were significantly lower than those in traditional caloric group (P ＜ 0.05).Conclusion Hypocaloric enteral nutrition can significantly reduce the stress hyperglycemia, abdominal distention, diarrhea, gastric retention and other gastrointestinal symptoms in patients with acute severe TBI.

Objective To evaluate the efficacy of artificial liver support system ( ALSS) combined with conventional medical treatment for liver failure .Methods Literature retrieval of Wanfang Data , CQVIP, CNKI, Medline, Cochrane Library and PubMed from 2004 to 2014 was conducted to identify all studies on ALSS in treatment of liver failure .The quality of the literature was assessed according to Cochrane systematic guide manual , and meta-analysis was performed using RevMan 5.3.Random-effects or fixed-effects model was performed based on the heterogeneity , and publication bias was evaluated with Begg ’ s funnel pot .Results A total of 20 randomized controlled clinical trials involving 2 356 patients were included for systematic review , among which 1 247 patients were treated with ALSS combined with medical therapy, and 1 109 patients were treated with medical therapy only .Meta-analysis showed that the mortality of patients with liver failure treated with combined therapy was 25.3%(316/1247), which was lower than that with medical treatment alone (524/1 109, 47.2%) ( OR=0.36, 95%CI:0.30-0.43, Z=11.19, P<0.01).The mortality of patients with acute (subacute) and subacute-on-chronic liver failure treated with combined therapy (54/203, 26.6%) was lower than that with medical treatment group (76/188, 40.4%) (OR=0.53, 95%CI:0.34-0.81, Z=2.91, P<0.01).The mortality of patients with chronic liver failure treated with combined therapy was 25.6% (89/347), which was also lower than that with medical treatment group (171/340, 50.3%) (OR=0.32, 95%CI:0.23-0.45, Z=6.73, P<0.01). Mortality in patients received medical treatment plus molecular adsorption recirculation system , plasma exchange or multiple ALSS were 23.6% (26/110), 21.9% (126/575) and 29.7% (80/269), which were significantly lower than those in patients received only medical treatment [38.9%(42/108), 52.2%(257/492) and 45.4%(103/227)] (OR=0.48, 0.24 and 0.45, 95%CI:0.26-0.88, 0.18-0.31 and 0.31-0.67, Z=2.38, 10.14 and 4.02, all P<0.05 or <0.01).Conclusion ALSS combined with medical therapy can reduce the mortality of patients with various types of liver failures .

Objective To investigate the occurrence law of autophagy in trophoblast cells from preeclampsia and its underlying mechanisms.Methods Twenty cases of placenta tissues were collected from women suffered from preeclampsia and normal pregnant women respectively.Autophagosome of trophoblast cells were observed by transmission electron microscope.The expressions of LC3-Ⅱ/Ⅰ and Atg4B in placenta tissues were detected by western blot and real-time PCR.Results Compared with the control group,typical autophagosomes of trophoblast cells were observed by transmission electron microscope.The ratio of LC3-Ⅱ / Ⅰ in placenta of PE patients was increased (1.43 ± 0.23) compared with control group (0.59 ±0.12),and the expression of Atg4B was up-regulated in both mRNA [(1.73 ±0.16) folds] and protein levels (0.71 ± 0.13) compared with control group (P ＜ 0.05).Conclusions Autophagy was significantly up-regulated in trophoblast cells from patients suffered from preeclampsia.Thus,all the data suggest that autophagy might be involved in the generation of preeclampsia.
