To explore the risk factors and features in patients with premature coronary artery disease (CAD) and mature CAD. Methods: General and clinical information was collected from 747 patients who received coronary angiography (CAG) in our hospital from 2015-01 to 2016-02 and the patients were divided into 3 groups based on CAG findings: Premature CAD group, n=138, Mature CAD group, n=364 and non-CAD group, n=245. CAD diagnosis was defined by at least one major coronary artery stenosis ≥50%; premature CAD was defined by the onset age in male<55 years, in female<65 years. Risk factors and features were compared between premature CAD and mature CAD patients. Results: Compared with Mature CAD group, Premature CAD group showed the higher incidences of family history of hypertension, abnormal blood glucose and BMI, increased blood levels of TC, TG, LDL-C, elevated apolipoprotein A and B (APOA and APOB); while the lower ratio for combining hypertension, P<0.05. Multinomial Logistic regression analysis presented the following parameters had the increased risk for premature CAD occurrence: combining hypertension and diabetes (OR=2.98, 95% CI 1.04-8.57), family history of hypertension (OR=3.50, 95% CI 1.28-9.57), abnormal blood glucose (OR=1.98, 95% CI 1.04-3.80) and elevated APOB (OR=36.67, 95% CI 3.51-99.83). The following parameters had the increased risk for mature CAD occurrence: advanced age (OR=1.20, 95% CI 1.15-1.24), male gender (OR=6.22, 95% CI 3.31-11.69), combining hypertension (OR=1.75, 95% CI 1.08-2.82), concomitant hypertension and diabetes (OR=3.25, 95% CI 1.42-7.46) and elevated APOB (OR=16.39, 95% CI 1.74-99.44). Compared with Mature CAD group, Premature CAD group presented the higher ratio of double vessel disease (38.4% vs 22.3%) and lower ratio of multi vessel disease (31.2% vs 48.1%), all P<0.05. Conclusion: The incidences as family history of hypertension, abnormal blood glucose and BMI, elevated APOB were higher in premature CAD patients than mature CAD patients. It is important to conduct targeted prevention to control relevant risk factors.

Neuroblastoma(NB),the common extracranial solid tumor of childhood,is thought to derive from neural crest cells.In disialoganglioside (GD)2 is highly expressed on NB,whereas GD2 expression is weak and restricted to the central nervous system,peripheral pain fibers and skin melanocytes.Therefore,GD2 is an ideal antigen target for immunotherapy of NB.The research progress on GD2 as target for immunotherapy of NB was reviewed.

Objective To investigate the value of soluble epithelial cadherin(sE-cad)in the differential diagnosis of pleural effusion. Methods Patients were divided into malignant pleural effusion group,infective pleural effusion group and transudation group.sE-cad in pleural fluids obtained during the first thoracocentesis was measured by enzyme-linked immunosorbent assay(ELISA).The concentration of sE-cad in all kinds of pleural effusions was compared.The cut-off value of sE-cad for the differential diagnosis of benign and malignant pleural effusion was determined by ROC curve.The diagnostic value of sE-cad was also compared with common tumor markers such as CEA,CA199,CA125 and NSE.Results The concentration of sE-cad was significant higher in the malignant pleural effusion than in the benign pleural effusion[(38.38?4.15)ng/mL vs(14.17?0.80)ng/mL,P

AIM: To investigate the quality of life in adults with strabismus and evaluate the improvement in quality of life after treatment.
METHODS: In this prospective study, forty-five adults with a diagnosis of strabismus conform to the inclusion and exclusion standard were selected in our hospital from October 2013 to May 2014, as experimental group and 45 normal adults were enrolled as control group. A Chinese Adult Strabismus-20 questionnaire was used to evaluate the differences of quality of life between patients with strabismus and normal adults, and to evaluate the differences of quality of life in patients with strabismus preoperative and 6mo postoperative.
RESULTS:The scores of quality of life in adult patients with strabismus preoperative and 6mo postoperative were statistically significant lower than those of normal adults (P< 0. 01). In 6mo postoperative, the scores of quality of life statistically significant increased than preoperative ( P<0. 01).
CONCLUSION: Strabismus can decrease the quality of life in psychosocial and visual functional for adults and the surgical treatment can improve quality of life in patients with strabismus.

Aim To investigate the effect of DHA on NGF-induced neuronal differentiation of PC12 cells and explore the possible mechanism via regulating BMP pathway. Methods PC12 cells were treated with 100μg·L-1 NGF and 100 μg·L-1 NGF + 10 μmol· L-1 DHA for 3, 6 and 9 days respectively. The length and number of neurite were detected by immunofluores-cenc. DHA content was analyzed by gas chromatogra-phy in all groups. The protein expression of BMP4, BMP7 , BMPR-II and p-Smad 1/5/8 was determined by Western blot. Results The length of total primary neurite in NGF+DHA groups was obviously increased, longer than that in NGF group; DHA content in 10μmol · L-1 DHA group was higher than that in the control group;NGF+DHA groups also unregulated the protein expression of BMP4 , BMP7 , BMPR-II and p-Smad 1/5/8 . Conclusion DHA promotes NGF-in-duced neuronal differentiation in PC12 cells, which may be associated with the upregulation of BMP path-way protein.

Objective To investigate the effects of electroacupuncture (EA) on affected and healthy limbs and on the regulation of insulin-like growth factor-1 (IGF-1) mRNA and proteins in the cerebral cortex early after focal ischemic.Methods A model of focal cerebral ischemia was established in 54 SD rats using the suture occlusion method.They were then randomly divided into an affected limb therapy group (ALTG,n =18),an unaffected limb therapy group (UALTG,n =18),and a control group (CG,n =18).Each group had a 7-day subgroup,a 14-day subgroup and a 21-day subgroup with 6 rats in each.Rats in the experimental groups received EA beginning 24h after the occlusion.Rats in each subgroup were sacrificed in a random order on the 7th,14th and 21st days and the ischemic cerebral cortexes were quickly dissected.The specimens were frozen in liquid nitrogen before being analysed for IGF-1 mRNA expression by RT-PCR and for IGF-1 protein by Western blotting.Results ①After occlusion,IGF-1 protein levels in the ischemic cortexes of the CG declined from the 7th through the 21st day.Rats in the ALTG had significantly higher levels compared with the CG at all time points.The UALTG had the highest values on the 14th day,but was lower than the ALTG and higher than the CG at the 21st day.②IGF-1 mRNA levels in the ischemic cortexes of the UALTG declined from the 7th through the 21st day.At day 7 the results of the UALTG were 6.8 times higher than the CG,and the ALTG was 3.0 times higher.At day 14 levels in the UALTG were significantly lower than those in the ALTG.At that point the results of the UALTG rats were 3.3 times higher than those of the CG and the ALTG was 5.7 times higher.On day 21 levels in both the UALTG and ALTG were significantly lower than in the CG.Conclusions EA intervention at an early stage of focal cerebral ischemia can improve the expression of IGF-1 mRNA and protein levels in the ischemic cortex.Treating the unaffected limb can evoke more IGF-1 mRNA expression earlier and with relatively longer duration,and generate relatively longer protein increases.EA administered to the unaffected limb was more effective in the early stage of stroke.

Objective To evaluate the usefulness of serum galactemannan(GM) for the diagnosis of invasive pulmonary aspergillosis (IPA) in critically ill patients. Methods Study was conducted between February 2007 and July 2008. Included patients on admission ICU who suffer from suspected IPA. GM test and culture were collected 2 weekly. Chnical feature, mycological evidence and optical density index (ODI) were noted. Clinically invasive fungal infection(IFI) were defined proven, probable and possible. The patients were classified into neutropenia, non-neutropenia and treated with immunosuppressive agents, non-neutropenia and non-immunosuppressive agents. To compared of the sensitivity and specificity of GM in different patients. Results 94 patients were included, 4 patients were proven, 29 patients were probable, 34 patients were possible IFI, 27 patients were non-IPA. The positive rate of the GM was 31.9% (30/94). The sensitivity and specificity of GM in proven cases and probable cases are 66.7% and 92.6%. GM assay tended to become positive earlier than the culture 2-10(5.33±2.17)d. We found that differences in patient diagnosis and selection might account for the disparities seen for positive rate for the GM test. There was positive in three of the four patients with proven, the positive rate of GM was 65.5% for probable cases, for possible cases was 17.6%, for non-IPA cases was 7.4% (P=0.001). For patient with neutropenia , treated with immunosuppressive agents and without immunosuppressive agents, the positive rate of GM was 52.9%vs 41.7% vs 34. 6% (P=0.015) ;the sensitivity was 80.0% vs 70. 0% vs 53.8% (P=0.011), the ODI was 1.365 (0.582-6.736) vs 1. 123 (0. 623-6.868) vs 0.554 (0.522-0.823), P=0. 005, respectively. Conclusion These results show that GM test is useful for early diagnosis IPA in critically ill patients. Differences in patient selection and diagnosis might account for the disparities seen for positive rate and sensitivity for the GM test. It has been higher sensitivity and ODI in the patient treated by immunosuppressive agents.

Objective:This work aims to investigate diallyl disulfide (DADS) inhibition of cell migration and invasion in human colon cancer SW480 cells through the Rac1-ADF/cofilin1 pathway. Methods:The potential of cell migration and invasion was examined by scratch healing assay and transwell membrane assay. The expression of Rac1-ADF/cofilin1 pathway was detected by RT-PCR and Western blot. Results:After the SW480 cells were treated with 40 and 50 mg·L-1 of DADS for 24 h, the number of transmembrane cells through the Matrigel obviously decreased by 57.12%and 64.59%, respectively (P<0.05). After cell treatment for 48 h, the cell migration rates were 23.23%and 12.87%, which were significantly lower compared with the control group (75.86%;P<0.05). After the cells were treated with 45 mg·L-1 of DADS for 24 and 48 h, the expression of Rac1, Rock1, PAK1, LIMK1, and destrin mRNA respectively decreased compared with the control group (P<0.05). However, no significant difference was observed in the expression of cofilin1 mRNA (P>0.05). After the treatment with 45 mg·L-1 of DADS for 6, 12, 24, and 48 h, the expression of Rac1, Rock1, PAK1, LIMK1, and Destrin proteins respectively decreased in a time-dependent manner compared with the control group (P<0.05). However, no significant differences were observed in the expression of the cofilin1 protein (P>0.05). Moreover, the expression of p-LIMK1 and p-cofilin1 notably decreased in a time-dependent manner (P<0.05). Conclusion:DADS inhibits cell migration and invasion, which is related to the down-regulation of Rac1, Rock1, PAK1, LIMK1, p-LIMK1, p-cofilin1, and destrin through the Rac1-ADF/cofilin1 pathway.
