The nutritional status in early life have been gradually recognized that it can change the status of development and metabolism of adults.Epidemiological evidence and animal model study have found that low birth weight is the risk factors of adult metabolic syndrome and cardiovascular disease.Insulin resistance is a common pathophysiological basis.Renin-angiotensin system and insulin signaling systems interact to promote the development of insulin resistance.

AIM: To investigate the early changes of retinal function in diabetic patients detected by multifocal electroretinogram (mfERG).METHODS: The first-order kernel responses of mfERG were recorded from eyes of 33 normal control subjects,63 diabetic patients without retinopathy and 43 diabetic patients with background retinopathy. The response densities and implicit times of N1 and P1 were compared among the control, diabetic patients without retinopathy and diabetic patients with retinopathy.RESULTS: The response densities of N1 and P1 in central 3 rings were reduced significantly in diabetic eyes with and without retinopathy. And the implicit times of N1 and P1 were delayed significantly only in diabetic eyes with retinopathy.CONCLUSION: mfERG can detect the early changes of retinal function quantitatively in diabetic patients. Analysis of response densities and implicit times of N1 and P1 can reflect the progress of local retinal dysfunction in diabetes.

AIM: To investigate the apoptosis and molecular mechanism of human hepatocellular carcinoma HepG2 cells induced by ginsenoside Rh4.METHODS: Human hepatocellular carcinoma HepG2 cells were treated with ginsenoside Rh4 at doses of 10, 20 and 40 μmol/L, and the inhibitory effect of ginsenoside Rh4 on HepG2 cell viability was measured by MTT assay.The apoptotic rate of HepG2 cells was analyzed by flow cytometry.The morphological changes of the HepG2 cells were observed by Hoechst 33258 and TUNEL staining.The expression of apoptosis-related proteins Bax, Bcl-2, caspase-3 and caspase-9 was determined by Western blot.RESULTS: Ginsenoside Rh4 promoted apoptosis of HepG2 cells in a dose-dependent manner.TUNEL and Hoechst 33258 staining showed that the cells appeared obvious shrinking, swelling and rupture after treated with ginsenoside Rh4 for 24 h.The results of Western blot showed that with the increasing concentrations of ginsenoside Rh4, the expression of pro-apoptotic proteins Bax, cleaved caspase-3 and caspase-9 increased, while anti-apoptotic protein Bcl-2 decreased gradually.CONCLUSION: Ginsenoside Rh4 induces apoptosis of human hepatocellular carcinoma HepG2 cells, and the main mechanism may be related to down-regulation of Bcl-2 and up-regulation of Bax, cleaved caspase-3, and caspase-9.

Objective:To analyze the activities of human NKG2D ligand MICA/B promoter induced by 5-Fu.Methods:The 5'-end flanking regions of MICA /B promoter and their different truncated fragments were amplified from A549 genome by PCR. The resulting amplicons were cloned into pGL3-Basic vector to generate the MICA/B luciferase reporter plasmids. All the constructs were transiently transfected A549 cells. The promoter region activities were determined by dual-luciferase reporter assays. The effect of 5-Fu on the promoter activities of MICA/B was also tested.Results and Conclusion:The 5'-end flanking regions of MICA /B promoter and five of their different truncated fragments were successfully obtained. The normalized luciferase reporter gene activities driven by the above promoters and fragments were 3.61,2.26,1.63,0.313,0.711 and 0.663 for MICA and 17.49,10.11,7.398,0.822,0.997 and 0.49 for MICB,respectively. Promoter activities in transiently transfected A549 cells treated by 20,40,80,160 and 320 μg/m of 5-Fu increased 1.69,1.48,1.62,1.55 and 1.78 fold for MICA and 1.44,1.87,1.38,1.19 and 1.25 fold for MICB. Our results suggest that 5-FU can significantly up-regulate the promoter activity of both MICA and MICB.

OBJECTIVE: To research the expression of alternative splicing segment of fibronectin-IIIcs in incised wound of skin, to offer the experimental data for early injury time judgement. METHODS: Using in situ hybridization with DIG-labeled anti-sense RNA probe, the expression of FN-IIIcs domain was detected in both human and rat skin incised wound. RESULTS: (1) The expression of FN-IIIcs improved from the time of 30 min after injury, reached peak at 6 h and then reduced gradually. (2) The positive expression cells were mainly distributed in hair follicles, sebaceous glands and endothelium, however, in human beings they were basement cells of epidermis. CONCLUSION The expression of FN-IIIcs domain would be a supposed useful criteria for early injury time judgement.

Allele-specific polymerase chain reaction (AS-PCR) is a technique based on allele-specific primers, which can be used to analyze single nucleotide polymorphism (SNP) effectively including the transition, transversion and insertion/deletion polymorphism and has been exploited in the study of diseases research, molecular diagnosis, and forensic biological evidence. The article systematically reviews the principle, the detection methods, improvement of AS-PCR, and its research updates in the fields of autosome, Y chromosome and mitochondrial SNP, as well as its application in forensic science.

Fibronectin is an important large adhesive glycoprotein of the extracellular matrix, which is alternatively spliced in three regions, designated EIIIA, EIIIB and IIIcs respectively. IIIcs contains two binding domains for a variety of cell surface and extracellular ligands. Through this multiplicity of adhesive activities, IIIcs can fulfill key roles in a broad spectrum of physiological processes, such as cell spreading and migration, differentiation and embryogenesis, wound healing, malignant transformation and metastasis, etc. Here, we will discuss the structure, biological property, and function of IIIcs splicing variants and its forensic applications.

Objective To study and observe the influence of atorvastatin for the CXCL chemokines and vascular endothelial damage indexes of patients with angina pectoris of coronary heart disease.Methods 86 patients with angina pectoris of coronary heart disease in our hospital from February 2016 to July 2017 were selected as the study objects, and all the patients were divided into the control group and the observation group with 43 cases in each group according to the random number table.The control group were treated with simvastatin on the basis of routine treatment, and the observation group were treated with atorvastatin on the basis of routine treatment.Then the treatment effect of angina pectoris, adverse reaction rates, CXCL chemokines and vascular endothelial damage indexes before and after the treatment of two groups were analyzed and compared.Results The total effective rate of observation group with angina pectoris was significantly higher than that of control group, so the difference had statistical significance (P＜0.05), the adverse reaction rates of two groups were compared, so the difference had no statistical significance (P＞0.05), the CXCL chemokines and vascular endothelial damage indexes of two groups before the treatment were compared, and the differenceshad no statistical significance (P＞0.05), the serum PGI2 of observation group after the treatment were lower than those of control group, the serum CXCL chemokines and other vascular endothelial damage indexes were lower than those of control group, and the differences had statistical significance (P＜0.05). Conclusions The treatment effect of atorvastatin in the patients with angina pectoris of coronary heart disease is better, and its safety is higher, and it has a better improvement role for the CXCL chemokines and vascular endothelial damage indexes, so it has a higher application value in the patients with angina pectoris of coronary heart disease.

Objective To review the surgical managements of patients with traumatic false aneu- rysms in the extremities.Methods From January 1990 to April 2006,17 patients with traumatic false aneurysms in the extremities were admitted into our hospital.Fourteen patients were treated by vascular repair including vascular repair in seven cases,end to end anastomosis in one,synthetic grafting in one, autogenous vein grafting in one,and direct ligation in four.Three patients were treated nonoperatively, but with local compressive dressing.Results There were no deaths or gangrenes in all cases.The clinical manifestations vanished after the treatment.The mean follow-up period was 13.2 months.The function of the injured extremities recovered satisfactorily.Conclusion Different types of traumatic false aneurysms should be managed by different therapeutic procedures after the diagnoses is made.
