Journal of Regional Anatomy and Operative Surgery 2016;25(5):379-381
Objective To summarize the prognosis of elderly patients with colorectal cancer excision who were divided into different groups by the nutritional status before their surgery.Methods In our hospital,100 patients (age from 64 to 70)with colorectal cancer were performed the screening of nutritional risk by NRS2002 before surgery.Patients with score from 1 to 2 were as the group A,and patients with score over 3 were as group B.The related indexes and recovery between two groups were compared.Results The NRS2002 rating scale score showed that 76 patients were at nutritional risk,37 cases among them received nutrition support and had faster recovery of intestinal function the time of tube pulled out after operation[(1.8 ±0.4)d vs.(2.9 ±1.5)d],exhaust time[(2.4 ±0.6)d vs.(4.3 ±0.9)d],time of in-take food[(2.9 ±0.5)d vs.(4.5 ±1.1)d],length of stay[(10.8 ±0.9)d vs.(14.1 ±1.3)d],incidence of infection related complica-tions (0 vs.5.13%),the differences were statistically significant(P <0.05).Conclusion Problems exist in varying degrees of loss of nu-trition in elderly colorectal cancer patients before surgery,an objective assessment of the extent and targeted care and nutritional support can significantly improve the postoperative nutrition and to facilitate recovery of gastrointestinal function after surgery.
3.The status, problem and progress of diabetic retinopathy treatment
Chinese Journal of Ocular Fundus Diseases 2016;32(2):206-210
Laser photocoagulation,intravitreal injection of antibody against vascular endothelial growth factor (VEGF) or corticosteroids and pars plana vitrectomy are current popular therapeutic approaches for diabetic retinopathy (DR).However,some DR patients still progress to irreversible blindness even after the above treatments which do not aim at the pathological mechanisms and influence factors for DR.Thus,with the further elucidation on the molecular pathological mechanisms and overall understanding of the factors affecting DR development,more and more potential therapeutic interventions such as neuron protection,vascular reconstruction and protection,gene therapy,non-VEGF dependent antineovascularization agents have been explored.Individual precise therapy based on the potential therapeutic targets would provide the promising future for DR patients.

Objective To investigate the effects of propofol on P2X7 receptor activition and IL-1β production induced by endotoxin in murine RAW264.7 macrophages. Methods RAW264.7 macruphages were treated with LPS (1 μg/ml) for 4 h to induce the production and release of IL-1β, and pretreated with BBG (specific P2X7 receptor antagonist) 1 μmol/L or propofol 1-100 μmol/L for 20 min before LPS stimulation, and IL-1β release was measured using ELISA kit. Whole-cell patch clamp technique was used to record the P2X7-gated currents induced by 1 mmol/L ATP, the cells were exposed to propofol with 1-1 000 -μmol/L for 4 min, and the IC_(50) level of propofol was achieved. Western blot technique was used to measure the production of pro-lL-1β protein and IL-1β protein intracellularly after LPS treatment for 4 h under different concentrations of propofol. Results IL-1β was released from RAW264.7 macrophages after LPS stimulation, which was decreased by propofol, and the IC_(50) level of propefol was (24±3) μmol/L. P2XT-gated currents were inhibited by propofol, and the IC_(50) level was (33±5) μmol/L. Pro-IL-1β protein intracellularly was up-regulated after LPS stimulation, and propofol with 3-100 μmol/L decreased the up-regulation of pro-IL-1β intracellularly induced by LPS. Conclusion Propefol could inhibit IL-1β release from RAW264.7 macrophages treated by LPS, which is mediated by inhibiting P2X7 receptor activition and decreasing the production of pro-IL-1β intracellularly.

Nuclear receptors(NRs)superfamily signaling plays an important role in regulating the expression of gene involved inenergy homeostasis.The nuclear receptors regulate target gene expression through the recruitment of coregulatory proteins,which act as scaffolds or plateforms for linking NRs with enzyme complexes that modify DNA and histones.As a transcriptional co-repressor for NRs,RIP140 negatively regulates the transcription of target gene in metabolic tissue,such as adipose tissue,muscle and liver.In the absence of RIP140,genes expressions involved in metabolic pathways were upregulated including glycolysis,triglyceride synthesis,TCA cycle,fatty acid ? oxidation,mitochondrial electron transport and oxidative phosphorylation.RIP140 may be a candidate therapeutic target for metabolism syndromes.

Objective: To evaluate the efficacy of the 45S5 bioactive glass on the reduction of hypersensitivity of teeth prepared for full coverage crowns.Methods: In the study, 31 prepared abutment teeth with vital pulp from 18 patients satisfied the inclusion criteria and exclusion criteria.The patients were informed consent and recruited into the study.This was a before and after self-control, single blind clinical trial.The severity of tooth hypersensitivity at baseline was evaluated, after application of the placebo, which was the powder of zinc oxide, and after application of the 45S5 bioactive glass on the same tooth.Tooth hypersensitivity was evaluated by Yeaple probe and visual analogue scale (VAS) when the tooth was stimulated by a fixed value of mechanical pressure and a blast of cold air respectively.And the dentist gave the subjective score, and the Schiff score at the same time.The three methods of measurement were repeated at baseline, after application of placebo and after application of the powder of 45S5 bioactive glass.Student''s t test and nonparametric test were used for statistical analysis.Results: The indexes measured at baseline, after the application of the placebo and after the application of the 45S5 bioactive glass were as follows, respectively: Tactile value (29.03±9.44) g, (29.68±9.48) g and (44.19±11.19) g, VAS value (50.79±22.92) mm, (46.63±22.06) mm and (30.90±20.30) mm, Schiff score 2.13±0.67, 1.97±0.66 and 1.42±0.56.After the application of bioactive glass, the values of Tactile, the VAS, and the Schiff score were statistically different from those at baseline or after application of the placebo (P<0.05).The data measured at baseline and after application of the placebo were of no statistical difference (P>0.05).Statistical differences between the Schiff scores of the groups were associated with gender, tooth position, primary or secondary tooth preparation.Conclusion: Results of the clinical trial showed that the powders of 45S5 bioactive glass were significantly effective on reducing the hypersensitivity of teeth with vital pulp after the full crown preparation.

Objective: To observe the clinical effect of Sertraline in treatment of dysthymia. Methods:63 outpatients diagnosed as dysthymia according to ICD-10 were randomly assigned to study group (n=33) and placebo group. Randomized double blind control study was done for 8 weeks with Sertraline from 50-200 mg/d. HAMA and HAMD were used to assess the effect.Results:At the end of 8 weeks, 54 patients completed the trial. Patients of both groups had lower HAMD scores than baseline from 2 weeks, and this trend continued through the 8 weeks observation. During this period, HAMD score of the study group declined more significantly than that of the placebo group. At the end of 8 weeks, the score of HAMA of the study group was also lower than that of the placebo group. The side effects of Sertraline were mild.Conclusion:Sertraline is effective in treatment of psychiatric outpatients with dysthymia.
