Objective To investigate the clinical safety of preoperative lymphatic chemotherapy in the treatment of reetal cancer.Methods The regional and systemic symptoms,postoperatwe stoma healing,haematogenesis.functions of hean,liver and kidney after lymphatic chemotherapy,and the level of CD3+,CD4+,CD8+,CD4+/CD8+,CD(16+56)+in blood 30 minutes before and 48 hours after lymphatic chemotherapv were detected.Results There were no significant effects of lymphatic chemotherapy on the regional and systemic symptoms,postoperative stoma healing,haematogenesis and the functions of heart,liver and kidney.The level of CD4+/CD8+48 hours after lymphatic chemotherapy was significantly increased(t=7.145,P＜0.05),while no significant changes of CD3+,CIM+,CD8+,CD(16+56)+were detected(t=1.782,1.151,1.184,0.955,P＞0.05),when compared with those 30 minutes before lymphatic chemotherapy.Conclusions Preoperative lymphatic chemotherapy is safe and can enhance patients'immunity in early stage.

Objective To compare the treatment effects between lymphatic chemotherapy and regional extended release chemotherapy (RERC) for rectal cancer lymph node metastasis. Methods The lymph nodes at or beside colon (first station), beside (second station) and at the root of mesentery blood vessel (third station) of the patients with rectal cancer in control group (20 cases), lymphatic chemotherapy group (20 cases) and RERC group (20 cases) were removed to compare proliferation index (PI), apoptotic index (AI) and AL/PI of cancer cells in the lymph nodes. Results The PI, AI, and AI/PI of cancer cells in correspondent lymph nodes were not statistically different between lymphatic chemotherapy group and the other 2 groups (F=4.973-7.394, 5.372-8.694, 4.527-5.436, P<0.05; t=3.128-7.688, 3.388-9.615, 6.518-13.180, P<0.05). The PI, AI, and AI/PI of cancer cells in the first and second station lymph nodes in RERC group were significantly different from those in control group (t=5.103, 4.927; 6.938, 6.450; 8.839, 9.021; P<0.05), and from those in the third station lymph nodes in RERC group (F=6.572, 8.964, 5.845, P<0.05; t=3.505, 3.353; 5.397, 4.701; 9.039, 8.629; P<0.05). Sorted by the treatment effects for cancer cells in lymph nodes, the first is each station of the lymphatic chemotherapy group, followed by the first and second station of the RERC group, and then the third station of the RERC group which was almost equal to any station of the control group. Conclusion Lymphatic chemotherapy is better than RERC in the treatment of rectal lymph node metastasis in the aspect of scale and degree.

AIM:To be one of the primary cause injury to multiple sites of ocular of glaucoma which affects over 70 million people worldwide. We applied data mining techniques, linear and the matrix operations, efficiently calculated the network and estimated the possible function of the“node” genes of the retina and optic of glaucoma, in order to provide new thought and method on the pathogenesis of glaucoma.
METHODS: The data in this study is from Gene Expression Omnibus ( GEO ) which belong to Nation Center for Biotechnology Information ( NCBI) , the quality of the raw data CEL files was processed and analyzed by the Expression software which belong to Affymetrix Inc. , Santa Clare, CA, USA. Significant analysis method ( SAM) which base on the T test was used to identified the significant genes. Based on GRNInfer and Gvedit soft we set up gene networks of optic and retina of mice and further more enriched analysis which based on DAVID and MAS3. 0 online software were processed.
RESULTS:The analysis between the group of the optic nerve heads and retinas in different stage of glaucoma showed that the amount of significant different expressed genes in the optic never head group increased significantly comparing with the group of retina in the early stage of glaucoma, the analysis of the genes network construction show that:the node genes of optic nerve heads included Unc13c、Kif5a、TRPM1、PANX; and the node genes of retina include POU4F1, NEFL, BC03870, CALB2. Metabolic pathways enrichment analysis which based on MAS3. 0 online platform show that there was mainly the amyotrophic lateral sclerosis, tyrosine metabolism, melanogenesis, Nitrogen metabolism, Gap junction, Leukocyte transendothelial migration metabolism pathway enriched out in optic nerve head; and there was mainly amyotrophic lateral sclerosis, neurodegenerative disorders, prostate cancer, leukocyte transendothelial migration metabolism pathway enriched out in retina.
CONCLUSION:By understanding bioinformatics result, it seems optic were more sensitive than the retina to high intraocular pressure, and weather high expression of TYrp1 gene can be as a sensitive diagnostic item require more evidence back up. Functional enrich analysis of node gene showed that cytoskeleton reconstructed, molecular motor and nutrients transport function improve in optic; and in retina, the most prominent finding in retina was enrichment function modules were focus on regeneration, repairing and differentiation of cells, which remind that we should reinforce research on reparation of retina of primary glaucoma. Metabolic pathways enrichment analysis show that inflammatory response plays prominent place in optic and retina of primary glaucoma, because of the optic narrow and crowed anatomic shape, nutrient metabolism and substances transfer enrichment modules play an important role in optics of primary glaucoma.

Objective To investigate the effect of sleep position guidance on deformational plagiocephaly and/or brachycephaly (DPB) in the prematures. Methods 321 preterm infants in neonatal intensive care unit from October, 2012 to September, 2015 were divided into sleep positions guidance group (n=159) and control group (n=162). The sleep positions guidance group accepted sleeping positions guidance when they were in neonatal intensive care unit and followed up in child care clinic, and the control group accepted routine treatment and nursing. The incidences of DPB were compared. Results The incidences of mild (χ2=6.591, P=0.010), moderate (χ2=4.862, P=0.027) and se-vere (χ2=11.261, P=0.001) DPB were less in the sleep positions guidance group than in the control group. Conclusion Sleeping positions guidance may reduce the incidence of DPB in prematures.

OBJECTIVETo investigate the clinical and pathologic characteristics of anti-glomerular basement membrane(GBM) disease with normal renal function.

METHODSThe clinical and pathologic data of 6 patients with anti-GBM disease and normal renal function in Peking Union Medical College Hospital were reviewed retrospectively. Furthermore, 29 patients with anti-GBM disease and impaired renal function in the same period in the same hospital were enrolled as the control group. Factors that may influence the prognosis were analyzed.

RESULTSSix (17.1%) of all 35 patients maintained normal renal function for 12-133 months during follow-up. Five patients had microhematuria and proteinuria, one had pulmonary hemorrhage only, and three manifested as Goodpasture syndrome. Renal biopsies from 4 patients revealed linear deposition of IgG 2+-3+ along the glomerular capillary walls by immunofluorescence. As shown by normal light microscopy, mild mesangial proliferation and crescentic glomerulonephritis with a large amount of fibrinoid necrosis of glomerular capillary walls were observed in different patients; however, most pathological changes were mild. Five of these six patients were treated with immunosuppressive drugs and/or plasma exchange. Compared with the control group, the 6 patients with normal renal function had significantly higher hemoglobin[(77.97±20.62 vs.(99.67±19.80 g/L P=0.024], lower titers of anti-GBM antibody[(224.34 ± 145.79 vs.(80.23 ± 85.73 EU/ml P=0.027], and lower ratio of glomeruli with crescents[(0.58±0.29 vs.(0.17±0.27 ,P=0.005]. These 6 patients with normal renal function were followed up for 12-133 months, among whom 4 patients achieved complete remission and 2 had mild proteinuria and microhematuria.

CONCLUSIONAnti-GBM disease with normal renal function is not uncommon. Most patients have mild pathologic changes and good prognosis.

Objective To investigate the ostengenie potential of adipose-derived stem cells(AD- SCs)when exposed to adenovirns containing hBMP-2 cDNA(Adv-hBMP-2)and offer a choice of cell source for gene therapy and tissue engineering.Methods Human adipose tissues were obtained from patients who received orthopaedic surgery or liposuction.ADSCs were obtained by digesting the adipose tissues.Firstly,flowcytometric analysis was performed for the confirmation of mesenchymal stem cell ori- gin and the surface markers including CD34,CD44,CD68,CD71,CD90,and CD105.The ADSCs were transfected by Adv-hBMP-2 and the effects were tested in vitro,lmmunoprecipitation and Western blotting and ELISA were performed for confirming BMP gone transduction and its stable expression.The transform of ADSCs was assessed by extracellular ALP staining,intracellular ALP spectrophotometry,von Kossa staining and RT-PCR.In the in vivo experiment ADSC-Adv-hBMP-2 cells were injected into the hind limb of nude mice and analyzed radiographically and histologically.Results ADSCs were successfully isolated from human adipose tissues.The isolated ADSCs expressed CD44,CD71,CD90 and CD105 and CD34 and CD68 were absent.The result confirmed the mesenchymal stem cell origin of the cells.West- ern blotting and ELISA confirmed successful and persistent hBMP-2 production by ADSC-Adv-hBMP-2 cells.Extracellular ALP staining,intracellular ALP spectrophotometry,yon Kossa staining and RT-PCR revealed that ADSCs treated with Adv-hBMP-2 had a tendency of transfering into osteoblast.X-ray and H&E sections from hind limb of nude mice injected with ADSC-Adv-hBMP-2 cells confirmed bone forma- tion at 2 weeks.Conclusions Liposuction aspirates contain abundant ADSCs that can be transduced with hBMP-2 gene,and the tranduced ADSCs differentiate into the osteoblast.ADSCs may be an ideal source of mesenchyme-lineage stem cells for gone therapy and tissue engineering.

OBJECTIVESTo investigate the serum leptin and adiponectin levels in nonalcoholic fatty liver disease (NAFLD) patients, and their relationship with insulin resistance.

METHODSA total of 120 cases were enrolled and divided into two groups: NAFLD group (n = 60) and normal control group (n = 60). The serum levels of leptin and adiponectin were measured by ELISA. The body mass index (BMI), waist-to-hip ratio (WHR), triglyceride (TG), total cholesterol (Tchol), high-density lipoprotein cholesterol (HDL-C) , aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), fasting blood glucose (FBG) and HOMA-IR (homeostasis model assessment insulin resistance) were detected and analyzed.

RESULTSCompared with control group, the serum leptin level in NAFLD group was Significantly higher [(12.37+/-1.99) microg/L vs (5.20+/-1.03) microg/L, P less than 0.01], while the serum adiponectin level was significantly lower [(12.69+/-2.83) mg/L vs (22.83+/-4.61) mg/L, P less than 0.01]. HOMA-IR was also much higher in NAFLD group than that in control group[(4.86+/-0.63) vs (1.91+/-0.41), P less than 0.01]. Logistic regression analysis showed that leptin was positively correlated with WHR (beta value = 8.175, P less than 0.01), HOMA-IR (beta value = 0.974, P less than 0.01 ), FBG (beta value = 0.564, P less than 0.01 ). In contrast, adiponectin inversely associated with HOMA-IR (beta value = -0.495, P less than 0.01 ) and BMI (beta value = -0.314, P less than 0.01) respectively.

CONCLUSIONThe increased serum leptin level and decreased serum adiponectin level in NAFLD patients independently associated with HOMA-IR.
