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.

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.

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.

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.

AIMTo study the relationship of neurotoxicity of 6-hydroxydopamine (6-OHDA) and the function of glutamate transporter.

METHODSUsing in vivo microdialysis together with high performance liquid chromatography (HPLC) to detect the alteration of glutamate in the striatum and extracellular fluid of the PC12 cell. The rate of apoptosis and the activity of PC12 cells are read in a flow cytometer and a photometer for enzyme-labeled assays. The function of glutamate transporter is decided by detecting the ability of L-[3H]-glutamate uptake.

RESULTS6-OHDA was shown to induce apoptosis and decrease the activity of PC12 cells. Increased release of glutamate was also found in PC12 cells and the injured striatum of the PD rats. But glutamate uptake in PC12 cells and rat striatum synaptosomes are inhibited obviously.

CONCLUSIONThe neurotoxicity of 6-hydroxydopamine is associated with declined function of glutamate transporters, which may be one important pathogenesis mechanisms of Parkinson's disease.

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.

OBJECTIVETo observe the protective effects of Tongxinluo (TXL) on apoptosis of rat cardiac microvascular endothelial cells (RCMECs) resulting from homocysteine (Hcy) induced endoplasmic reticulum stress (ERS), and to determine the signaling pathway behind its protection.

METHODSPrimary cultured RCMECs were isolated from neonatal rats using tissue explant method. The morphology of RCMECs was observed using inverted microscope, identified and differentiated by CD31 immunofluorescence method. Selected were well growing 2nd-4th generations of RCMECs. The optimal action time was determined by detecting the expression of glucose regulated protein 78 (GRP78) using immunofluorescence method. In the next experiment RCMECs were divided into 5 groups, i.e., the blank control group, the Hcy induced group (Hcy 10 mmol/L, 10 h), the Hcy + TXL group (Hcy 10 mmol/L + TXL 400 µg/mL), the Hcy +LY294002 group (Hcy 10 mmol/L + LY294002 5 µmol/L, LY294002 as the inhibitor of PI3K), the Hcy + LY294002 + TXL group (Hcy 10 mmol/L + LY294002 5 µmol/L + TXL 400 µg/mL). The apoptosis rate of RCMECs was detected by flow cytometry. mRNA and protein expressions of GRP78, C/ EBP homologous protein (CHOP), and cysteinyl aspartate specific proteinase-12 (caspase12) were detected by real-time reverse transcription PCR (RT-PCR) and Western blot respectively. Expression levels of phosphorylation of phosphatidylinositol 3-kinase (P-PI3K), total phosphatidylinositol 3-kinase (T- P13K) , phosphorylation of kinase B (P-Akt) , and total kinase B (T-Akt) were detected by Western blot.

RESULTSTen hours Hcy action time was determined. Compared with the blank control group, the apoptosis rate was increased (22.77%), mRNA and protein expressions of GRP78, CHOP, and Caspase-12 were increased, protein expressions of P-PI3K and P-Akt,ratios of P-PI3K/T-PI3K and P-Akt/T-Akt were decreased in the Hcy induced group (P < 0.05, P < 0.01). Compared with the Hcy induced group, the apoptosis rate was decreased (10.17%), mRNA and protein expressions of GRP78, CHOP, and Caspase-12 were decreased, and expression levels of P-PI3K, P-Akt, P-PI3K/T-PI3K, and P-Akt/T-Akt were increased in the Hcy + TXL group (P < 0.05, P < 0.01). Compared with the Hcy + TXL group, the apoptosis rate was increased (17.9%), mRNA and protein expressions of GRP78, CHOP, and Caspase-12 were increased, expression levels of P-PI3K and P-Akt, ratios of P-PI3K/T-PI3K and P-Akt/T-Akt were decreased in the Hcy + TXL + LY294002 group (P < 0.05, P < 0.01).

CONCLUSIONTXL could inhibit the apoptosis of RCMECs resulting from Hcy-induced ERS and its mechanism might be associated with activating PI3K/Akt signaling pathway.
