AIM: To observe the therapy effect of standard prescription on ametrop amblyopia in hyperopic children.
METHODS: This study included 270 cases ( 54 eyes ) with complete data, and followed up 24mo. All the amblyopic children were given standard prescription and were divided into progressive addition glass group, under corrected group and full corrected group. And all were observed for their therapy effect and the average healing time in low hyperopic, moderate hyperopic and high hyperopic children with ametropic amblyopia respectively.
RESULTS: In low hyperopic children, the difference of the therapy effect of the three corrected methods were insignificant in two years. The meam cure time of the three corrected methods were ( 7. 33 ± 2. 11 ) mo in progressive addition glass group;(9. 0±3. 71)mo in under corrected grope;(12. 5±5. 17) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=1. 66, P>0. 05) was statistically insignificant; the difference between progressive addition glass group and full corrected grope ( t = 3. 92, P < 0. 01 ) was statistically significant; the difference between under corrected grope and full corrected grope ( t = 2. 33, P < 0. 05 ) was statistically significant. In moderate hyperopic chileren, the differences of the therapy effect of the three corrected methods were significant in two years (χ2=6. 75;P<0. 05). The difference between progressive addition glass group and under corrected grope (χ2 = 6. 3; P < 0. 01 ) was statistically significant; the difference between progressive addition glass group and full corrected grope (χ2=8. 1;P<0. 005) was statistically significant. The mean cure time of the three corrected methods were ( 14. 0±4-87) mo in progressive addition glass group; ( 16. 93±4-58)mo in under corrected grope; (17. 93±4. 42) mo in full corrected group. Three groups of independent samples by paired t-test showed: the difference between progressive addition glass group and under corrected grope (t=2. 88, P<0. 01) was statistically significant; the difference between progressive addition glass group and full corrected grope ( t= 3. 9, P<0. 01 ) was statistically significant;the difference between under corrected grope and full corrected grope ( t = 1. 01, P > 0. 05 ) was statistically insignificant. In high hyperopic amblyopic children, the difference of the therapy effect and the healing time of the three corrected methods were insignificant in two years. (χ2=2. 43, P>0. 05. t=1. 49, P>0. 05;t=1. 46,P>0. 05;t=1. 11, P>0. 05).
CONCLUSION:Under standard prescription, application of progressive multifocal glasses provides a new effective treatment for ametropic amblyopia in hyperopic children, and makes up the deficiency of the whole straightening and under correction in clinical treatment.

Objective Preparing platelet rich gel through two-times centrifugal technique and co-culturing chondrocytes with PRG, then observing the proliferation and gene expression of chondrocytes, in order to provide a favorable way to prepare tissue engineering cartilage. Methods Centrifugating venous blood of rabbit through two-times centrifugal technique to obtain platelet rich plasma( PRP) ,then detecting the concentration of various growth factor in PRP. Admixing PRP with chondrocytes of rabbit and activating them with activator. After co-culti-vation,the proliferation of chondrocytes through MTT method and expression of ACAN,CollagenⅡand SOX-9 through realtime-PCR were ob-served,and compared with common cultured chondrocytes. Results The concentrations of PDGF-AB,TGF-β1,IGF-1 and VEGF in PRG were significantly higher than those in blood(P<0. 05). After co-cultivation, the proliferation rate of chondrocytes and the expression of ACAN,Collagen Ⅱ and SOX-9 were significantly higher than that of common cultured chondrocytes(P<0. 05). Conclusion Co-culturing chondrocytes with PRG is able to promote the proliferation and gene expression of chondrocytes. We considered that it is a excellent method to construct tissue engineering cartilage.

On account of the dense cuticles of the fresh stem and the light, hard and pliable texture of the dried stem, Dendrobii Caulis is difficult to dry or pulverize. So, it is very important to the ancient doctors that Dendrobii Caulis should be properly treated and applied to keep or evoke its medicinal effects. The current textual research results about the preliminary processing, processing and usage methods of Dendrobii Caulis showed that: (1) In history the clinical use of fresh or processed Dendrobii Caulis as teas and tinctures were very common. (2) Its roots and rhizomes would be removed before using. (3) Some ancillary approaches were applied to shorten drying times, such as rinsing with boiling mulberry-ash soup, washing or soaking with liquor, mixing with rice pulp and then basking, etc. (4) According to the ancients knowledge, the sufficient pulverization, by means of slicing, rasping, hitting or pestling techniques, was necessary for Dendrobii Caulis to take its effects. (5) The heat processing methods for Dendrobii Caulis included stir-baking, stir-frying, steaming, decocting and stewing techniques, usually with liquor as an auxiliary material. Among above mentioned, steaming by pretreating with liquor was most commonly used, and this scheme was colorfully drawn in Bu Yi Lei Gong Pao Zhi Bian Lan (Ming Dynasty, 1591 CE) ; moreover, decocting in advance or long-time simmering so as to prepare paste products were recommended in the Qing Dynasty. (6) Some different processing programs involving stir-baking with grit, air-tightly baking with ondol (Kangs), fumigating with sulfur, which appeared in modern times and brought attractive outward appearance of the drug, went against ancients original intentions of ensuring drug efficacy.

To understand the adverse drug reaction (ADR) induced by Mailuoning injection. 162 ADRs due to the drug were retrieved from national medical journals of 1988-2007 for statistics. It was shown that there was no relationship between ADR and dosage, but ADR appeared mostly in middle-aged and old groups, and more in male than in female. The occurrence of ADR was commonly within 30 min after injection. It involved injuries of various systems and organs. As for the 123 cases of allergy, 38 were anaphylactic shock (accounting for 23.46%), two people died. ADR characterized by immediate type on initial use and tachy type. It should be paid more attention to the Mailuoning injection for the immediate hypersensitivity reaction (such as anaphylactic shock).

Re-evaluation of bioequivalence of generic drugs is one of the key research focus currently. As a means to ensure consistency of the therapeutic effectiveness of drug products, clinical bioequivalence has been widely accepted as a gold standard test. In vitro dissolution testing based on the theory of the BCS is the best alternative to in vivo bioequivalence study. In this article, the conventional dissolution method and flow-through cell method were used to investigate the dissolution profiles of domestic amoxicillin capsules in different dissolution media, and the absorption behavior of the drugs with different release rates (t85% = 15-180 min) in the gastrointestinal tract was predicted by Gastro Plus. The flow-through cell method was thought better to reflect the release characteristics in vivo, and amoxicillin capsules with regard to the release rates up to 45 min (t85% = 45 min) were having a satisfied bioequivalence with the oral solution according to the C(max) and AUC. Although two different dissolution profiles of domestic amoxicillin capsules were found by flow-through cell methods, prediction results revealed that domestic capsules were probably bioequivalent to each other.

Objective To determine the relationship between the level of plasma homocysteine and coronary calcification in patients with different blood glucose levels. Methods By measuring plasma homocysteine and coronary calcification in 30 cases of diagnosed diabetes (T2D) ,29 cases of diagnosed impaired glucose tolerance (IGT) in patients and 27 cases with normal, we compared the level of plasma homocysteine and coronary calcification in patients with different blood glucose levels. Results We found significant diffieronces among three groups of the level of plasms homocysteine and coronary calcification (P ＜ 0.01). The plasma homocysteine levels were(19.31 ±3.17) μmol/L, (13.85 ± 1.62) μmol/L, (9.80 ± 1.78) μmol/L in the T2D,IGT and normal groups,respectively. The coronary calcification scores were 207.80 ± 154.10,63.24 ± 10.46,14.47 ± 5.16 in the T2D, IGT and normal groups, respectively. The plasma homocysteine level and coronary calcification score increased with the glycosylated hemoglobin rise in the normal,IGT and T2D groups((4.51 ±0.48)%, (6.13 ±0.31)% and (7.69 ±0.81)%, respectively). Conclusions The plasma homocysteine level is a strong independent predictor of type 2 diabetes and also an important factor of coronary artery event occurrence and develepment.

Endostatin is a potent, endogenous inhibitor of angiogenesis, which corresponds to the C-terminal fragment of collagen ⅩⅧ. The human endostatin gene was amplified from a human fetal liver cDNA library by means of PCR and was cloned into pPIC9K vector. Soluble endostatin was superexpressed in Pichia pastoris (50.5mg/L) . The recombinant protein was purified by cation exchange chromatography with the final yield of more than 95%. Western blotting analysis showed positive immunoreactivity to the expressed product. Recombinant endostatin was able to suppress the angiogenesis on the CAMs. Also, the endostatin inhibited specifically of the migration of HMECs stimulated by bFGF, with EC50 being about 0.4 ?g/ml.

AlM: To study clinical reference value of retinal microvascular changes in patients with cerebral microbleeds ( CMBs) and discuss its clinical significance.
METHODS:From January 2012 to December 2013, 125 hospitalized patients were collected, including 81 cases were male, 44 cases were female, mean age 76. 3 ± 11. 2 years old. For all patients, functions of liver and kidney, blood - lipoids, blood sugar and blood biochemical examination were tested, and fundus photography and cerebral MR was done. According to the fundus camera eyes, retinal arteriolar equivalent ( RAE) , retinal venular equivalent ( RVE) , retinal vein diameter ratio ( AVR) and arteriovenous crossing sign ( AVN ) were identified, CMBs were classified with cerebral MRl. All the data were processed by SPSS statistical software.
RESULTS: The central retinal arteriolar equivalent (CRAE), central retinal venular equivalent (CRVE) and AVR values in the eyes were found no statistical difference (P<0. 05). Of CMBs classification, the grade 0 in 75 cases, 1 in 27 cases, 2 in 9 cases and 3 in 14 cases were included. The RVE, AVR and AVN and the different grades of CMBs had statistically significant correlation ( P<0. 01). The higher CMBs classification, the more obvious retinal microvascular changes were found. ln respectively to eliminate risk factors such as age, sex, blood glucose and blood pressure, AVR and AVN were still influencing factors for CMBs classification.
COCLUSlON: The results show that retinal microvascular changes, especially small retinal vein arteriovenous cross width, and arteriovenous crossing phenomenon, in which CMBs will happen more likely. After sex, age, hypertension and hyperglycemia in patients with traditional cardiovascular risk factors being ruled out, the retinal microvascular changes are still relatively factors of CMB's occurrence.
