2.Study of informing cancer patients of the disease with the optimized security strategy based on AQ score
Journal of International Oncology 2012;39(9):709-712
ObjectiveTo study the optimized security strategy for informing cancer patients with the disease,and let patients be fully informed and even more actively cooperate with doctors while they are under treatment.MethodsGrouped with adversity quotient (AQ) score,these cancer patients were in comparison with those who had been informed by other ways without support strategy,and different groups of patients were estimated in different strategies in accordance with self-rating anxiety scale (SAS) and self-rating depression scale (SDS).Results With certain strategies,high and low AQ score groups' SAS and SDS scores stably restored in 1 day to 1 week,and the differences had statistical significance(P < 0.01 ).The patients were well-informed without any difficulty and actively cooperated with treatment.No related factors led to self-mutilation,suicide and other serious incidents.While the SAS and SDS scores of the control group who were not informed by the strategy were not satisfactorily recovered,and the patients could not actively cooperate with the doctors.Especially being notified after 1 d to 1 week,the SAS and SDS scores had no significant improvement,and the differences had no statistical significance compared with themselves ( P > 0.05 ).It is difficult to avoid the occurrence of serious incidents.Conclusion Based on AQ score,it is safe and effective to inform cancer patients of their disease condition by individual strategies.It not only respects patients rights,but also gains the active cooperation of the patients,and is helpful for treatment with minimizing adverse effects.
4.Oxidative stress response in diabetic nephropathy rats following injection of embryonic stem cells via the tail vein
Chinese Journal of Tissue Engineering Research 2015;(14):2199-2204
BACKGROUND:Occurrence and development of diabetic complications is closely related to the severity of oxidative stress imbalance in the body. OBJECTIVE:To investigate the effect of embryonic stem cel s on oxidative stress response of rats with diabetic nephropathy. METHODS:Primarily cultured rat embryonic stem cel s were observed for cel morphology and surface antigen detection. Sprague-Dawley rats were divided into experimental group (two injections of embryonic stem cel s via the tail vein), model group (injection of the same volume of PBS), and normal control group (with no modeling, intraperitoneal injection of sodium citrate-citrate buffer). In the former two groups, the rats were intraperitoneal y injected sodium citrate-citrate buffer diluted streptozotocin to establish diabetic nephropathy models before treatment. At 5 weeks after the last injection, blood glucose level, renal function indicators (urine protein/urine creatinine, blood urea nitrogen and serum creatinine) were tested in each group;contents of malondialdehyde and protein carbonyl were detected in the kidney;the expression level of superoxide dismutase was detected by western blot assay. RESULTS AND CONCLUSION:The embryonic stem cel s were oval or round, with clear boundary and good refraction, and highly expressed Oct-4 and SSEA-1. Compared with the control group, renal biochemical indicators, malondialdehyde and protein carbonyl contents were significantly increased, while the expression level of superoxide dismutase was decreased dramatical y in the model group and experimental group (P<0.05);compared with the model group, the renal biochemical indicators, malondialdehyde and protein carbonyl contents were dropped significantly in the experimental group, but the expression of superoxide dismutase was significantly rebounded (P<0.05). Taken together, embryonic stem cel s can reverse the occurrence and development of diabetic nephropathy by inhibiting oxidative stress in progress.

Objective To investigate the expression of serum vascular endothelial growth factor (VEGF) in children with Wilms tumor,and clarify the effect of VEGF in the invasion and progression of Wilms tumor.Methods Thirty children with Wilms tumor who underwent surgical treatment were retrospectively analyzed as Wilms tumor group,the control group was 30 children who underwent treatment by cold and fever symptoms.The serum VEGF levels of 2 groups were detected by enzyme-linked immunosorbent assay.Results The serum VEGF level of Wilms tumor group was significantly higher than that of control group [(567.90 ± 189.30) ng/L vs.(55.46 ± 18.49) ng/L,t =14.757,P <0.05].The expression of serum VEGF was closely related to NWTS stage,prognosis tissue type and lymph node metastasis (P < 0.01).The expressions of serum VEGF in the NWTS Ⅲ-Ⅳ stage,lymph node metastasis and poor prognosis tissue type Wilms tumor were significantly higher than those of NWTS Ⅰ-Ⅱ stage,without lymph node metastasis,good prognosis tissue type Wilms tumor (P< 0.01).Conclusions The expression of serum VEGF is high in children with Wilms tumor,the serum VEGF level is closely related to NWTS stage,prognosis tissue type and lymph node metastasis.The high expression of serum VEGF shows the invasion,progression and poor prognosis in children with Wilms tumor.
8.Morphological characteristics of eggs of Trichuris in humane, domestic and wild animals
Chinese Journal of Zoonoses 2005;(7):545-547
The whipworm,Trichuris trichiura,has a worldwide distribution but is more common in tropical and subtropical areas and in regions where sanitation is poor.The common name of whipworm is most descriptive,the thick posterior part of the body forming the stock,and the long thin anterior portion.The adult worma are from 3 to 5 cm long,the female worm is longer than the male worm.On the posterior part is pinkish gray and contains the intestine and reproductive organs. Diagnosis is by demonstraion of the characteristic barrel-shaped eggs (50-54 by 22-23μm)usually found in the stool.But their morphology of adult worms and eggs among the human,domestic and wild animals are quite different to diagnosis.The females are larger(35-55 mm long)than the males(30-45 mm).Each female worm can produce 3,000 to 70,000 eggs daily.The eggs are lemon-like with a plug at each end.Their size are 50-54 μm and 22-23 μm respetively.
9.Application of biological patch in pelvic restoration and reconstruction
Chinese Journal of Tissue Engineering Research 2010;14(3):529-532
BACKGROUND: Understanding of patch classification, characteristics, and reaction with host is necessary for best selection of reparative surgery materials.OBJECTIVE: To summarize the patch classification, characteristics and its application in pelvic reconstruction, as well as the complications.METHODS: A computer-based online search of PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) and CNKI database (www.cnki.net/index.htm) was performed for related articles with the key words "patch, polypropylene, compound patch" in Chinese and "reconstructive pelvic surgery, repair, replacement" in English. Articles regarding patch classification, characteristics biocompatibility, and application effect, or in the same circle published recently in authoritative journals were included. A total of 24 articles were finally selected.RESULTS AND CONCLUSION: Polypropylene patch is weaved network, with large mesh, which allows for fiber tissue ingrowth and improves tissue intensity and tensile strength. Leukocyte and macrophage can enter the mesh, so the patch has good anti-infection ability. Expanded polytetrafluoroethylene is soft and smooth, with good tissue tolerance, and can prevent affixion with intraabdominal tissues. Moreover, the submicron pore diameter prevents bacteria invasion. The inflammation and foreign body reaction induced by the expanded polytetrafluoroethylene is the most slight among artificial synthetic materials.
10.Effect of Ginkgo biloba extracts on hippocampal apoptosis in diabetic encephalopathy rat
Chinese Journal of Diabetes 2010;18(2):143-146
Objective To study the relation between diabetic rat encephalopathy and hippocampal apoptosis, and the therapeutic effect and mechanism of Ginkgo biloba extract. Methods Sixty rats were assigned into control group(NC), diabetic encephalopathy group (DM+B) and EGb-treatment group (EGb) randomly, and every group was further divided into two time points of 1 month (NC_1 ,DM+B_1, EGb_1 ) and 3 month(NC_3 ,DM+B_3, EGb_3 ). The behavioral abnormalities were investigated by water maze test and the apoptosis levels of brain tissue by ELISA. Immunohistochemistry and RT-PCR were performed to determine the protein and mRNA expressions of Bcl-2 and Bax. Results (1) Mild dysfunction of learning and memory was detected in DM+B_1 group, and the dysfunction became worse in DM+B_3 group. The matters were greatly improved in EGb-treatment groups. (2) The expressions of Bcl-2 protein and mRNA were increased in DM+B_1 and DM+B_3 groups, and were stronger in EGb_1 and EGb_3 groups. (3) The expressions of Bax protein and mRNA were obviously increased in DM+B_1 and DM+B_3 groups, and were dramatically reduced in EGb_1 and EGb_3 groups. (4) Compared with control group, the apoptosis level of brain tissue was increased in DM+B_1 group, and obviously greater in DM+B_3 group. In the EGb-treatment groups the levels were dramatically reduced. Conclusions Diabetic encephalopathy may be closely related to hippocampal apoptosis. EGb has an protective effect and the mechanism may be attributed to its effects inhibiting apoptosis.
