Modern perinatal and neonatal medical advances make the survival rate of extremely low birth weight infants(ELBWI) higher,but its neurodevelopmental impairment,growth stasis and health status are poor.The survival rate of our county is lower than that of developed countries.In China,there are a few reports on neurodevelopment injury of ELBWI.This review will summarize prevention and prognosis on neurodevelopmental of ELBWI.

The pathogenesis of diabetic retinopathy is complicated.The vast network of multiple factors including unifying mechanism,inflammatory reaction,neuron degeneration and metabolic memory of glucose,and the four established pathogenic molecular pathways are hotspots of mechanism research for diabetic retinopathy.Nevertheless,these researches may be only one corner of the iceberg of DR mechanism,and we still face enormous challenges in DR mechanism research.Collaboration with multiple disciplines to study the relationship between DR and diabetes and other systemic diseases,search novel therapy targets may increase the result in an unexpected windfall for DR basic research.

Aim To investigate the effects of ampelopsin on induction of apoptosis in human hepatocellular carcinoma Bel-7402 cells.Methods Bel-7402 cells were treated with ampelopsin with different concentrations for 24,48 and 72 h.The cell proliferation was detected by MTT assay.The morphological change of cells was observed through microscope observation by fluorescence staining.DNA fragmentation was visualized by agarose gel electrophoresis.The apoptosis rate was analyzed by flow cytometry.The expressions of caspase-3,Bcl-2 and Bax protein were detected by Western blot.Results Ampelopsin inhibited the proliferation of Bel-7402 cell line in a dose-and time-dependent manner.The IC50 values were 89.6?16.1,36.2?6.5 and 15.3?3.0 mg?L-1 at 24,48 and 72 h,respectively.The fluorescence microscope showed clearly cell apoptosis with apoptotic body.Agarose gel electrophoresis result showed that Bel-7402 treated with ampelopsin produced a DNA ladder band.The sub-G1 peak was detected and resulted in dose-and time-dependent increasing of the population of sub-G1 DNA content by flow cytometry.The expression of Bcl-2 protein was down-regulated,while the expression of Bax protein was up-regulated.The pro-caspase-3 protein was down-expressed and activated.Conclusions Ampelopsin could inhibit Bel-7402 proliferation through inducing cell apoptosis.The mechanism might be that ampelopsin could directly or indirectly enhance the level of anti-apoptosis protein Bcl-2 and decrease the level of apoptosis protein Bax.The pathway of pro-caspase-3 activated was initiated and effector caspase-3 was sequentially activated.

ObjectiveTo investigate the effects of atorvastatin on cardiomyocyte apoptosis and caspase-3 expression in acute myocardial infarction in rats.MethodsFifty SD rats were randomly divided into 3 group:sham group,control group( normal saline),atorvastatin pretreatment group ( 10mg/kg),The atorvastatin group were pretreated with atorvastatin ( 10mg/kg ) for 3 days,and those in the control group were pretreated with normal saline instead.All rats underwent coronary ligation of left anterior descending branch to establish AMI rat s model on the fourth day except the sham group,while sham group only received thoracotomy without coronary ligation.Then,The infarct size area at risk were defined by Evans blue and TTC staining,the caspase-3 mRNA expression of myocardium was measured with reverse-transcriptase polymerase chain reaction(RT-PCR) and the apoptosis index was analyzed by TUNEL staining.Results Compared with control group,the infarct size,the caspase-3 mRNA expression of myocardium,the apoptotic index were decreased significant in the atorvastatin group ( P ＜ 0.05 ).ConclusionPretreatment with atorvastatin has protective effect on the acute ischemic cardiomyocytes,which may probably be associated with the reduction of the expression of caspase-3 mRNA in the myocardium and the apoptotic index.

Objective: To assess the effect of Linghuang powder (LHP) in treating acute nonspecific lower urinary tract infection (ANLUTI) with lower-Jiao damp-heat syndrome and evaluate its safety. Methods: A randomized controlled design was adopted. Four hundred and fourteen patients were allocated to LHP treatment group, control group and open treatment group. Results: The markedly effective rate of short-term treatment with LHP was 71.78%, and the total effective rate was 92.02%, the total rates of improving urine routine and urine bacterium were 95.21% and 79.37% respectively in LHP treatment group. Conclusion:The effect of LHP for ANLUTI with lower-jiao damp-heat syndrome is better than that in the control group (P

This review was made to compare the multimedia teaching results with traditional teaching results in medical universities or colleges.Two kinds of opposite viewpoints appeared:the multimedia teaching results was better or worse than the latter.

The effect of metabolic syndrome on patients with pre-diabetes in regard to cardiovascular and cerebrovascular diseases (CCVD) was investigated.The subjets with pre-diabetes were divided into metabolic syndrome (MS) group and non-MS.Follow-up after the baseline survey,the new-onset cardiovascular events of patients were collected.The incidence of CCVD in the MS group was 5.66％,being higher than 1.88％ in non-MS group (P＜0.05).After factors being corrected,compared with the non-MS group,the relative risk (RR) of CCVD in MS group was 2.616 (95％ CI 1.328-5.153).Compared to only 1 component of MS patients,the risks of CCVD in MS component 2,≥3 patients were increased by 29％ (HR =1.29) and 62％ (HR =1.62).Metabolic syndrome may increase the risk of cardiovascular and cerebrovascular diseases in pre-diabetes populations.The occurrence of CCVD and MS content showed a dose-dependent relationship.
