The imaging findings of pelvic lipomatosis as confirmed by operation and pathology were examined in 1 case and two follow-up asymptomatic cases retrospectively analyzed.The imaging findings included a compressed and deformed bladder with a superior displacement.Its shape was like an inverted tear and pear in coronal view and a banana in sagittal view.Bilateral ureters were both compressed with a medial deviation.And bilateral ureters were dilated with hydronephrosis in 1 case.Rectum and sigmoid were both compressed and became narrowed.The clinical manifestations included frequent urination , urgent urination , urination pain, dysuria, constipation, nausea, vomit and fever in 1 case while another 2 cases stayed asymptomatic.

Pneumonia is one of the most common medical complications after stroke.Stroke-associated pneumonia (SAP) can not only increase the length of hospital stay and medical cost of patients,but also an important risk factor for mortality and morbidity in patients with stroke.All these indicate that the importance of prediction and prevention of SAP.This article reviews the advances in research on the prediction and prevention of SAP.

Objective:Normal murine DCs were pulsed with complex of tumor antigen from elemene-combo tumor cell vaccine-heat shock protein 70 of BCG (H TA-HSP70 BCG).Their proliferation and antigen presenting function were evaluated.Methods:The dendritic cells(DCs)were cultured in complete media containing GM-CSF and IL-4 and pulsed with H TA-HSP70 BCG,H TA or HSP70 BCG.Their proliferation and stimulating effects on spleen nonadherent cells were evaluated with MTT assay.Their capability of endocytosing FITC labeled dextran was assayed with FACscan,morphological changes of DC were observed in electron microscope.Results:Proliferation index of DCs pulsed with H TA-HSP70 BCG was 2.107?0.013,proliferation index of DCs pulsed with H TA-HSP70 BCG mixed with normal nonadherent spleen cell was 1.927?0.073.The percent of DCs endocytosed FITC labeled dextran was 58.61%.Above changes were more significant than those of DCs pulsed with H TA or HPS79 BCG.Conclusion:H TA-HPS70 BCG had more potent activity to pulse DC and strengthen antigen presenting of DC.

Objective To study the effects of Poly(I:C) on lung adenocarcinoma A549 cells viability and illuminate the mechanism of Poly (I:C)-induced apoptosis in A549 cells.Methods A549 cells were transfected with the complex of Poly(I:C) and lipofectamine 3000.The viability of A549 cells was tested by methyl thiazolyl tetrazolium (MTF) method.The apoptotic cells were tested by flow cytometry.The caspase proteins were tested by Western blotting and the expressions of interferon-β (IFN-β) and CXCL-10 were assayed by real-time PCR.After employing the pan-caspase inhibitor Z-VAD-FMK and caspase-8 inhibitor Z-IETD-FMK,the variation of Poly (I:C) proapoptosis in A549 cells was observed.RNA interfering experiments were employed to knock down melanoma differentiation related antigen 5 (MDA5) or retinoic acidinduced gene Ⅰ (RIG-Ⅰ),and the above indexes were tested.Results The viability of A549 cells was significantly reduced to 74.92％ ±--6.24％ after 200 ng/ml Poly (I:C) transfection compared with that before transfection (95.32％ ± 3.05％,t =2.883,P =0.041).The apoptotic rates induced by 100,200,400 ng/ml Poly(I:C) were 9.97％-± 0.88％,23.63％-± 1.41％,32.57％-± 2.39％,respectively.All of them were higher than that in the control group (0.74％-± 0.15％),with significant differences (t =4.489,P =0.002;t =11.616,P =0.000;t =16.932,P =0.000).Besides,the death receptor pathway proteins such as TNF-related apoptosis inducing ligand (TRAIL),cleaved-caspase-8 and cleaved-caspase-3 increased obviously.MDA5/RIG-Ⅰ pathway was also activated dramatically and the expressions of IFN-β,CXCL-10 were significantly up-regulated.The apoptotic rates reduced to 3.17％ ± 0.66％,5.35％ ± 0.64％ with pancaspase inhibitor Z-VAD-FMK and caspase-8 inhibitor Z-IETD-FMK pretreatment,compared with the control group (15.87％ ±0.93％),and the differences were statistically significant (t =8.643,P =0.001;t =6.824,P =0.002).Moreover,the expressions of TRAIL,IFN-β and CXCL-10 induced by Poly (I:C) were inhibited with MDA5 or RIG-Ⅰ depletion.Conclusion Poly(I:C) can reduce the survival rate of A549 cells and promote the apoptosis mainly by activating the death-receptor pathway mediated by MDA5/RIG-Ⅰ probably,which may involve in IFN-β,CXCL-10.

AIM: To determine the optimal operation method and reduce operative complications by retrospective analysis of outcomes of different operative manipulation for patients with congenital ectopia lentis ( CEL) .
●METHODS: A retrospective study ranged from Jan. 1, 2010 to Jan. 1, 2015 was conducted and 31 CEL patients (57 eyes) treated with different operations were taken into this study. The postoperative outcome, operation related complications was analyzed in terms of different operative manipulations.
● RESULTS: The most common types of CEL are idiopathic and Marfan - related CEL. All eyes ( 98%) benefited from operation except 1 Marchesani syndrome eye concurrent with optic atrophy induced by glaucoma. A total of 3 eyes ( 5%) were treated by phacoemulsification combined with intraocular lens implantation; 8 eyes ( 14%) were treated by phacoemulsification, capsular tension ring implantation combined with intraocular lens implantation, among these 8 eyes, 1 eye was treated with capsular tension ring implantation combined with suture fixation; 39 eyes ( 68%) were treated by lens excision and anterior vitrectomy through corneal incision combined with intraocular lens implantation with suture fixation, among these 39 eyes, 2 eyes were treated with trabeculectomy , but not combined with intraocular lens implantation; 5 eyes ( 9%) were treated by intracapsular cataract extraction and anterior vitrectomy combined with intraocular lens implantation with suture fixation; 2 eyes ( 4%) were treated by lens excision and vitrectomy through pars plana combined with silicon oil injection.
● CONCLUSION: Almost all patients can obtain satisfactory outcomes through various operative manipulations. Phacoemulsification combined with intraocular lens implantation was the first choice for patients with lens dislocation range less than 90°. Phacoemulsification, capsular tension ring implantation combined with intraocular lens implantation was recommended for 90° - 180°, and lens excision and anterior vitrectomy through corneal incision combined with intraocular lens implantation with suture fixation was more suitable for lens dislocation range more than 180°. The appropriate operative methods for different types of CEL patients is the key to success.

AIM:To investigate the effects of silent information regulator 1 (SIRT1) on high glucose-induced acetylation of NF-κB p65 subunit and its protective role in rat mesangial cells .METHODS:Rat mesangial cells were cul-tured in DMEM supplemented with 10% FBS and were divided into control group , mannitol group , high glucose group , resveratrol group and SIRT1 RNAi group.The cell viability was determined by MTT assay .The mRNA expression of SIRT1, monocyte chemoattratant protein 1 (MCP-1), vascular cell adhesion molecule 1 (VCAM-1-1), tumor necrosis fac-torα( TNF-α) , transforming growth factor β1 ( TGF-β1 ) was analyzed by real-time quantitative PCR .The protein expres-sion of SIRT1 and the acetylation of NF-κB p65 subunit were determined by Western blotting .The protein concentrations of MCP-1, VCAM-1, TNF-α, TGF-β1 and malondialdehyde (MDA) were detected by ELISA.RESULTS:The cell viabili-ty, superoxide dismutase (SOD) activity, and the expression of SIRT1 at mRNA and protein levels were decreased by high glucose treatment as compared with control group .The acetylation of NF-κB p65 subunit was significantly increased after interfered with high glucose , resulting in the increase in the secretion of MCP-1, VCAM-1, TNF-αand TGF-β1 .Resvera-trol decreased high glucose-induced acetylation of NF-κB p65 subunit.However, silencing SIRT1 significantly enhanced the acetylation of NF-κB p65 subunit and the expression of MCP-1, VCAM-1, TNF-αand TGF-β1 .CONCLUSION:SIRT1 remarkably inhibits the inflammatory reactions by deacetylating NF-κB p65, suggesting that SIRT1 is a possible tar-get for preventing diabetic nephropathy .

Objective To investigate the efficacy of the combination ofJiangtang decoction and insulin in the treatment of type 1 diabetes mellitus in children.Methods A total of 43 children with type 1 diabetes mellitus were enrolled and randomly allocated to either a insulin group (control group) and a insulin plusJiangtang decoction group (treatment group) using the table of random digits, with 23 patients in the control group and 20 in the treatment group. The patients in the control group were treated with insulin, and those in the treatment group were administrated withJiangtangdecoction on the basis of the treatment in the control group for 2 months. Body mass index (BMI), fasting plasma glucose (FPG), postprandial blood glucose (PBG) and hemoglobin A1c (HbA1c) were measured.Results The levels of FPG, PBG and HbA1c were significantly decreased in the treatment group (twere 3.376, 54.493, and 2.798, respectively; allP<0.01), and the PBG level was significantly decreased in the control group (t=29.714,P=0.000). The levels of FPG, PBG and HbA1c in the treatment group were significantly lower than those in the control group (twere 2.715, 2.191 and 5.627, respectively;P<0.05 orP<0.01). There was no difference in BMI between the treatment group and the control group (t=0.159,P=0.874). The proportion of patients with HbA1c <7.5% in the treatment group (60.0%, 12/20) was higher than that in the control group (26.1%, 6/23;χ2=5.055,P=0.025).Conclusion Combination ofJiangtang decoction and insulin can decrease the level of FPG, PBG and HbAlc, and its therapeutic effect is superior to insulin alone for type 1 diabetes in children.

Objective To investigate whether black cohosh could be improve patients with breast cancer treated chemotherapy like-menopausal symptoms through a non-estrogen pathway.Methods We selected 120 patients with breast cancer dianosised and treated chemotherapy from January 2012 to June 2013 in four Affiliated Hospital of Harbin Medical,which were female patients,20-51 years,preoperative menopause,menstrual regularly,postoperative chemotherapy timely and regularly,and Kupperman score ≥ 15 points.All patients were randomized,double-blind divided into two groups,the experimental group was treated with medication Li Fumin Black Cohosh Extract,40 mg once daily,the other one was treated with placebo,40mg once a day.After 12 weeks,all patients were checked by estrogen hormones,gynecological ultrasound,the ultrasound of the other breast,Kupperman score,Then we make an assessment with those.Results During the experimental group and the control group,estrogen and endometrial thickness were within normal range,and there are not statistically significant difference between before and after medicine(P ＞ 0.05).What's more,before and after medication,the experimental group and the control group were not found new breast lumps.After taking medicine,the Kupperman score of experimental group was significantly lower than before treatment,the difference was statistically significant (P ＜0.05); however,there was not statistically significant difference between before and after medicine for the Kupperman score in control group(P ＞ 0.05).In experimental group,there are 5 cases of patients,which Kupperman is more 15 points,but lower than the score before taking medicine.Conclusions Black cohosh could improve like-menopausal symptoms of patients with breast cancer treated chemotherapy through a non-estrogen pathway,regardless of estrogen-receptor positive or negative,which has a good effection.
