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 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.

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.

Aim To research the effect of diltiazem on cytokine expression and inflammatory cell activity in rat heart with ischemia/reperfusion.Methods The rats, underwent ischemia reperfusion, were divided into three groups:diltiazem group(D group),ischemia/reperfusion group (I/R group),and sham group (Sgroup).Echocardiogram was detected at 1,2,4 weeks after operation. RT-PCR was used to detect the inflammatory cytokines as IL-1β,TNF-α, IL-6 and anti-inflammatory cytokines as IL-10,TGF-β.Results Compared with I/R group,EF were increased and LVM, IL-β,TNF-α,IL-6 reduced significantly in D group.There was no significant/difference for IL-10 and TGF-β in three groups .Conclusion Diltiazem inhibits IL-1β,TNF-α, IL-6 expressions and inflammatory cell infiltration in rat heart with ischemia reperfusion.

OBJECTIVE: To investigate the expression and clinical significance of EphA2 and E cadherin proteins in papillary thyroid carcinoma tissues, and to explore the relationship between them. METHOD: Using immunohistochemical SP/PV method, we detected the expression of EphA2 and E cadherin in tumors of 43 papillary thyroid carcinomas, 11 thyroid adenoma and 10 normal thyroid tissues, then studied their relationships with clinic pathological factors. RESULT: The total positive rates of EphA2 and E cadherin expression were 58. 14% and 32. 56% in papillary thyroid carcinoma tissues, 18. 18% and 81. 81% in thyroid adenoma.tissues and they were 10. 00% and 100. 00% in normal thyroid tissues respectively. The positive expression of EphA2 in carcinoma tissues was higher than in the thyroid adenoma tissues and normal thyroid tissues (P<0. 05) and the positive expression of E cadherin in carcinoma tissues was lower than that in the thyroid adenoma tissues and normal thyroid tissues (P<0. 05). The positive expression of EphA2 and E cadherin was associated with lymph node metastasis and histological grade (P<0. 05), but it was not associated with all the clinic-pathological factors including age, sex and the tumor size (P>0. 05). In papillary thyroid carcinoma tissues, the expression of EphA2 was negatively correlated with the expression of E cadherin protein (r= -0. 416, P<0. 01). CONCLUSION EphA2 and E cadherin may be involved in carcinogenesis and development of papillary thyroid carcinoma.

Malignant tumors are the most common lethal diseases in China.Because of complexity of etiology and pathogenesis , and the lack of specific markers for early diagnosis , delayed diagnosis and treatment of cancer , the fatality rate is high.With the development of basic research , more and more early specific markers were found , but the current detection mostly depend on the professional laboratories , time-consuming , high price and have a number of inconveniences to patients on time and money.Meanwhile , it′s difficult to extend to zoon of medicine resources deficient.Recently, point-of-care testing (POCT) has been rapidly developed , because of its portability , getting results quickly , can be operated in basic medical units and economic backward areas , so it′s benefit to cancer screening in human.By the application in tumor markers, POCT can be done for the cancer early detection , early diagnosis and early treatment , so then cuts the death rate.

Gc subtyping had been achieved and Gc variants were detected using this method without using anfi-Gc serum for immunofixation. Two new Gc variants Gc~(1c3) and Gc~(2c7) were discovered in Chinese people, and their frequencies were 0.0008 and 0.0004 respectively.

Objective To investigate the relationship between angiotensin I-converting enzyme(ACE)inserting/defaulting(I/D) gene polymorphisms and the femoral artery intima-media thickness(FA-IMT) in patients with type 2 diabetes mellitus(T2DM).Methods The polymorphisms of ACE(I/D) was determined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) method and the FA-IMT was assessed using non-invasive high resolution B-mode ultrasonography in 303 patients with T2DM in Hunan province.Results The frequency of I allele of ACE gene polymorphisms was higher in T2DM than that in healthy controls,but frequency of D allele was lower in T2DM than that in healthy controls(P
