Abstract?AlM: To observe the anterior chamber angle shape of patients with diabetic retinopathy ( DR) at different stages using OCT, and to explore a more sensitive and accurate glaucoma preventing measure.?METHODS: A total of 613 cases of DR patients were divided into proliferation phase group ( 353 cases ) and background phase group ( 260 cases ) , another 100 cases of patients with only diabetes were selected as control group. OCT was used to detect the anterior chamber angle related parameters, including angle opening distance ( AOD) , trabecular-iris space area ( TlSA) , angle recess area ( ARA ) , anterior chamber depth ( ACD ) and anterior chamber angle ( ACA) .?RESULTS: There were significant difference among AOD500, AOD750, TlSA500, TlSA750, ARA500 and ARA750 of control group, proliferation phase group and background phase group ( P< 0. 01 ). The proliferation phase group was the lowest, AOD500, AOD750, TlSA500, TlSA750, ARA500 and ARA750 were 0. 60 ± 0. 22mm, 0. 78 ± 0. 39mm, 0. 22 ± 0. 12mm2 , 0. 45 ± 0. 19mm2 , 0. 29 ± 0. 18mm and 0. 46 ± 0. 15mm, respectively. There were significant difference among ACA500, ACA750, ACD500 and ACD750 of control group, proliferation phase group and background phase group ( P< 0. 01 ). The proliferation phase group was the lowest, ACA500, ACA750, ACD500 and ACD750 were 30. 29o ± 8. 19o, 21. 20o ± 7. 40o, 2. 32 ± 0. 23μm and 2. 52±0. 16μm, respectively. ln addition, ROC results indicated that all these indices exert significant difference on evaluating the stage of DR. ?CONCLUSlON: Anterior chamber angle shape detected using OCT can reflect the change of retinopathy. OCT is an accurate and simple technique for detecting DR staging.

AIM To study the antiperoxide damage of injectio tanshin during dissolving thrombus to cure the acute myocardial infarction(AMI). METHODS AMI model formatted by electricity to irritate the left ventricular branch of coronary artery of open-chest rabbit,and observation aspects including electrocardiogram(ECG),cardiac output and contractility,serumal enzymatic activities and biochemistry and pathology of lipid peroxide extent of myocardial infarction zone. RESULTS By urinate kinase(UK) combining with injection tanshin,abnormal changes of ECG, descending of cardiac contractiles and cardiac output,going up of serum cardiac damage enzyme(CPK-MB and LDH),and the malondialdehyde(MDA)of serum and myocardial infarction zone could be remarkably reduced or avoided during UK dissolving the thrombus to cure AMI rabbits. CONCLUSION Injection tanshin can clearly reduce or avoid lipid peroxidation damage during UK dissolving the thrombus to cure the acute myocardial infarction.

Objective To study the regularity of compound herbal formulae for renal fibrosis (RF). Methods Compound herbal formulae published about the treatment of RF in databases of Chinese Science and Technology Periodical Database, CNKI, Chinese Biomedical Literature Service System, and Wanfang Databasewere searched and collected. A database was established for data mining by using frequency analysis, cluster analysis and association rule analysis. Regularity of key herbs and groups of herbs was discussed. Results There were 38 prescriptions (totally 95 herbs) in the compound herbal formulae for RF, and the total frequency was 362 times. High frequency herbs under cluster analysis were classified into 3 clusters including tonic, hemorheologic agent and promoting diuresis drugs. The rules in pair of herbs were 18, and rules in group of herbs were 31 (three or four medicinal herbs) by using association rule analysis. Conclusion Tonifying promoting blood circulation and removing blood stasisis a common sense for treating RF.

OBJECTIVE: To investigate the allergens in patients with allergic rhinitis in Yichang, so that to find common allergens of Yichang and to provide statistic basis for a reasonable prevention and treatment to allergic rhinitis. METHOD: 1,979 patients with allergic rhinitis in Yichang were detected for allergens by skin prick test and the distribution of positive rates to inhaled allergens was compared between different genders and ages. RESULT: 1,545 (78.1%) of 1,979 suspected allergic rhinitis patients presented positive reaction. The positive rate in male was significantly higher than in female, and that in juvenile group was significantly higher than in adults. Among positive cases in inhalation group, the most common allergen was flour mite (80.4%), followed by house dust mite (64.9%), cockroach (13.3%) and artemisia pollen (8.2%). CONCLUSION The study shows that the flour mite and house dust mite are the most common inhaled allergens causing allergic rhinitis in Yichang. We should pay more attention to the prevention and treatment for the juvenile patients.

Objective To explore influence of JAK/STAT3 signaling pathway on the apoptosis of HCC cells.Methods DNA-vector-based RNAi approach silence was used to down-regulate STAT3 expression in Bel-7402 cells.According to the STAT3 cDNA sequence in the GeneBank database,the plasmid pGCsi.U6/neoRFP-STAT3 that was designed for expression of STAT3 siRNA was constructed and synthesized,and then transfected into the Bel-7402 cells with iipofectamine 2000.The apoptotic rate was measured with flow cytometry (FCM) and annexinV/PI apoptosis detection kit staining.The mitochondrial membrane potential (BΨm) was visualized by the JC-1 fluorescence staining and the inverted fluorescence microscope.Moreover,the expression of caspase-3 protein was analyzed by Western blotting.Results The apoptotic ratio of STAT3-siRNA group was (38.82 ± 0.88) ％,which was significantly higher than that in other group [control group (9.22 ± 0.38) ％,scramble-siRNA group (16.47 ± 1.04) ％,P ＜ 0.05].The mitochondrial membrane potential of STAT3-siRNA group observed by the JC-1 fluorescence staining was decreased significantly[(91.33 ± 1.78) ％] and [(89.90 ± 1.92) ％ vs (59.06 ± 1.89) ％,P ＜ 0.05].The Western blot results showed that the protein expression of active caspase-3 in STAT3-siRNA group was significantly higher than other groups (0.48 ± 0.05 vs 0.22 ± 0.04 and 0.26 ± 0.06,P ＜ 0.05).Conclusions STAT3 gene silencing significantly improves the apoptotic effect in the Bel-7402 ceils.

BACKGROUND:Polyvinyl alcohol is a biocompatible and biodegradable polymer. It is widely used in clinical areas because of its water-soluble, film forming, emulsification, adhesiveness, tasteless, and nontoxic.
OBJECTIVE:To review the applications of polyvinyl alcohol and its composite materials in bone, cartilage, skin, vessels and other tissue engineering scaffolds.
METHODS:A computer-based online search of CNKI database from January 2000 to December 2011, PubMed database and Elsevier (ScienceDirect) database from January 1980 to December 2012, was performed by the first author with key words of“poly(vinyl alcohol), composite material, tissue engineering scaffold”both in Chinese and English. Literatures concerning polyvinyl alcohol and its composite materials in bone, cartilage, skin, vessels and other tissue engineering scaffolds were included, and repetitive research was excluded.
RESULTS AND CONCLUSION:Although there are not enough strength, complications and other shortcomings in vivo, due to its good biocompatibility and biodegradable properties, polyvinyl alcohol and its composite
materials have made great progress in tissue engineering applications from the laboratory to the pre-clinical
research. But its long-term effects need further research. It wil be a main research aim of scaffold materials in the future to improve the interaction of cel s with the scaffold materials by surface modification, to prepare biomimetic materials by cel microenvironment simulation, to improve the hydrophilicity, the adhesion of cel s, and cel
differentiation and proliferation, to bionic the structure and function of the natural extracel ular matrix by building three-dimensional porous structure and control ing the release of cel growth factors, to meet the need of tissue regeneration by congruity or harmony of degradation and mechanical strength.
