Background Microvessels are composed of two interacting cell types: endothelial cells and pericytes. Over the past decades, studies of corneal angiogenesis have concentrated mainly on endothelial cells, while interest in pericytes has lagged behind. Objective The present study aimed to investigate the recruitment of vascular endothelial cells and pericytes in rat corneas after alkali burn. Methods Corneal alkali burn models were established in the right eyes of 36 adult SPF SD rats by putting 4 mm medicators containing a 1% 1 mol/L NaOH solution at the central corneas for 30 seconds, and 3 matched normal rats were used as controls. Corneas were excised 1,2,3,5,7 and 10 days after surgery. Frozen sections that parallel with the corneoscleral limbus were constructed. Double immunofluorescence staining was used to observe the dynamic expression of CD31 and α-smooth muscle actin (α-SMA) in corneal tissue for the evaluation of the number of endothelial cells and pericytes. The pericyte coverage index (PCI) was calculated to quantify the recruitment of pericytes to neovascular sites. The use of experimental animals followed the Statement of Association for Research in Vision and Ophthalmology. Results CD31 was expressed in the superficial stromal layer of the cornea on the 1 st day, showing the presence of red fluoresence. The positive cell number for CD31 was gradually increased with the passage of time and proceeded into the deep stromal layer from days 2 through 5 but decreased after that. However,α-SMA was positively expressed on the 2nd day in the cornea after alkali burn with the presence of green fluorescence. The positive cell number for α-SMA was less than those of CD31 throughout the experimental period. The PCI was 0, 16.07%, 11.95%, 43.84%, 73.97% and 86. 21% , respectively, 1,2,3,5,7 and 10 days after surgery. Conclusion Pericytes recruitment to corneal new vessels may play a key role in the stabilization and maturation of angiogeneis.

AIM: To explore the skills and characteristics of corneal neovascular model in rat induced by micropocket assay. ·METHODS: Nine eyes of nine Sprague-Dawley rats were studied. Pellets made of vascular endothelial growth factor (VEGF), poly-2-hydroxylethylmethacrylate and sucralfate were implanted into the corneal stroma nocloser than 1mm from the limbus. Biomicroscopic features of corneal neovascular were observed on 1,3, 5, 7th day after the implantation. ·RESULTS: On day 1 after operation, the limbal vessels were dilated, with no angiogenesis appeared. On day 3, angiogenesis began to invade peri-cornea with a brush shape, the area of CNV was (2.23±0.59) mm2. On day 5, new vessels reached the lower margin of pellet densely, the area of CNVwas (6.81±1.35)mm2. On day 7, new vessels continued to elongate, parts of them extended as loops toward the pellet, the area of CNV was (8.92± 1.79)mm2. Neither hyphema or other complications occurred.·CONCLUSION: Corneal neovascular induced by micropocket assay in rat grows steadily, with no complication, and is suitable for quantitative researches.

OBJECTIVEObserve and analyze the informations of western medicine and traditional Chinese medicine in patients with coronary heart disease (CHD), in order to provide reference for clinical treatment.
METHODSelect patients with CHD in diagnosis of the first place in 17 hospitals, drug informations of these patients were analyzed using frequency method and association rules.
RESULTIn 84 697 patients,there were 47 564 males and 32 882 females. The median age was 71 years old, 76 172 patients have medicine records, including 278 kinds of western medicine and 331 kinds of traditional Chinese medicine. Aspirin was the most common used western medicine (51 132 patients, 67.08%), followed by isosorbide dinitrate, clopidogrel etc. The most common used traditional Chinese medicine was danhong injection, followed by shuxuetong injection. After classified the drugs, at the forefront of western medicine were antiplatelet drugs, nitrates drugs, statins, beta blockers, calcium antagonists, ACEI; the most used in traditional Chinese medicine was injection of blood-activating and stasis-resolving, followed by oral preparations of blood-activating and stasis-resolving medicine, Fuzheng class oral medicine, purgation medicine etc. After association rules, combination therapy among western medicine was the most common, combination of western medicine with blood-activating and stasis-resolving was very commonly, especially antiplatelet drugs and nitrates drugs.
CONCLUSIONWestern medicine in the treatment of patients with CHD was in accordance with the guidelines recommend, but with the lower utilization rate. Traditional Chinese medicine has become an important method for the treatment of CHD, promoting blood circulation and removing blood stasis is an important part of traditional Chinese medicine treatment in patients with CHD.

This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.

This study aims to assess if adverse drug reactions (ADRs) to Kudiezi injection are allergic in origin. Hospital information system (HIS) data from 18 hospitals in China were used to carry out a nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving Kudiezi injection. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on solvents had a significant effect, P values were 0.005 5 and < 0.000 1 on suspected cases of allergic reactions. For the first subgroup analysis, we found using other eight injections at the same time as Kudiezi injection could be risk factors in suspected cases of allergic reactions. For the second subgroup analysis combining using mannitol or fructose could increase risks. Based on this current research, condition on admission as well as the concomitant use of some other drugs may be the risk factors in suspected cases of allergic reactions. However, further research for verification is required. This study can provide guidance for safe clinical practice in using Kudiezi injection.
