AIM: To observe the expression of COX-2 in rat corneal neovascularization (CNV) and its relationship to CNV, and to explore the inhibition of Celecoxib, a COX-2 inhibitor, to CNV.METHODS: The distribution and quantification of COX-2and VEGF was detected by immunohistochemistry. Expression of COX-2 and VEGF mRNA was quantified by RT-PCR.The difference in protein and mRNA expressions of COX-2and VEGF was analyzed to find the correlation between them.RESULTS: Expression of activated COX-2 and VEGF protein and mRNA in CNV had a dynamic change. VEGF and COX-2co-localized. Compared with the control group, expression of both protein, mRNA of COX-2 and VEGF in experimental group Ⅱ and Ⅲ had significant difference (P＜0.05), indicating the correlation between COX-2 and VEGF, while that in experimental group I had no statistical difference (P＞0.05).CONCLUSION: COX-2 expression was up-regulated in inflammatory CNV. COX-2 modulates the expression of VEGF,playing a very important role in CNV. Celecoxib inhibit COX-2expression so as to hold back the CNV.

Objective]To study the correspondence between human and universe theory in Shanghan Lun starting with Zhongjing ’s doctrine of treatment based on four seasons,analyse the influence of the changing seasons on giving names to the six meridians by Zhongjing ,research on the influence of pulse theory based on four seasons in Huangdi Neijing on the pulse system includes the six meridians system ,summarize the rules of the four seasons’ influence on the six meridians system in Shanghan Lun,and return to Zhongjing’s original viewpoint of four seasons and their yin and yang condition. [Method]By studying the Treatise on Four Seasons treatment Dafa Six Classics and veins in the school system, restore Treatise on Heavencorresponding way of thinking. [Result] It finds that seasons law is the core of six distinguished by its Zhongjing school system clock. [Conclusion] Studying the Four Seasonslaw andseasons therapy Dafa can know Treatise on Six by the corresponding season and six by the significance and reflects theTreatise onlearning system from four seasons pulse method.

Objective] The explanations of the six meridians theory in the book Shanghan Lun were always divergent, most of them explained it with medical theory of later ages.However, il ustrating it from the philosophic perspective was not commonly seen. Yi Jing, the book of changes, was the origin of traditional Chinese philosophy, and the six meridian system, which included three yin and three yang, was just derived from the four xiang(a traditional Chinese concept which refers to taiyang, shaoyin, shaoyang, taiyin). [Method] Through the eight trigrams and the images were analyzed with the Treatise on Six Classicsstate gasification combined with analysis Zhongjing Six Classics theoretical system and the principle of prescription. [Result] Found that eight trigrams can be good images of the corresponding six by the system, the difficult provisions in Tretise on Febrile Diseases were wel explained. [Conclusion]Through combining the images of Bagua(eight trigrams) in Yi Jing with six meridians in Shanghan Lun,il ustrating six meridians from philosophic aspect, and explaining the six meridians theory with philosophical ideas before Zhongjing ’s(the writer of Shanghan Lun) age, in order to provide new ways of thinking in comprehending the six meridians system.

Esophageal cancer is one of the common malignancies of the digestive tract, and its exact etiology and pathogenesis have not been completely clear. The establishment of animal model of esophageal cancer provides support for the basic and preclinical research of esophageal cancer, which is of great significance for further study to clarify the pathogenesis and explore the development of new therapeutic drugs. At present, the animal models commonly used in the study of esophageal squamous cell carcinoma mainly include chemical induction model, heterotopic transplantation model and orthotopic transplantation model. With the continuous progress of animal research on human origin tumor, the human transplanted tumor model has been more and more widely used. No matter which model has its own advantages and disadvantages and applicability, should be selected according to the purpose of the experiment. In this paper, the research progress on animal models of esophageal squamous cell carcinoma in recent years is reviewed, and the models commonly used in scientific research and preclinical treatment are discussed, which may provide a theoretical basis for the clinical treatment.

Objective Through the evaluation of acute myocardial infarction patients care burden of caregivers,to understand caregiver stress con?dition,and to investigate the effective predictors of acute myocardial infarction patients care burden of caregivers,so as to provide the basis for im?provement of the care burden. Methods A cross?sectional study was conducted through convenience sampling using Zarit Caregiver Burden Inter?view as the measuring tool. Questionnaires were collected by face?to?face structured interviews towards caregivers. Care burden of caregivers was eval?uated on these primary caregivers of patients with acute myocardial infarction. Results Caregivers of patients with myocardial infarction endure high care burden level. There were statistically significance among patients with different ages or revenue,the relationship of caregivers with patients,nurs?ing hours per day,psychological alignment and patients′self?care ability. Conclusion Caregivers of patients with myocardial infarction endure high care burden level. The relationship between caregivers and patients,the patient′s gender,nursing total time,nursing time every day,and the pa?tient's life self?care ability are contributed to be predictive factors. Future interventions should be strengthen on the psychological ability of the align?ment as well as measures to improve the self?care ability of the patient's life.

This paper is aimed to establish the method of fingerprint analysis of chemical constituents by reversed-phase ultra-performance liquid chromatography (UPLC) for the quality control of the roots and rhizomes of Panax ginseng (Ginseng Radix et Rhizoma). The method was performed on a ACQUITY UPLC BEH C18 (50 mm x 2.1 mm ID, 1.7 microm) with a mixed mobile phase of water and acetonitrile in a gradient mode. The flow rate was 0.3 mL x min(-1) and the wavelength of measurement was 203 nm. Eleven batches of the Ginseng Radix et Rhizoma were determined. The UPLC chromatographic fingerprints of chemical constituents were established from the eleven batches of the Ginseng Radix et Rhizoma and showed fifteen characteristic common peaks, among which fifteen peaks were recognized and nine compounds (ginsenosides Rg1, Re, Rf, Rg2, Rb1, Rc, Rb2, Rb3 and Rd) were determined by comparison with chromatographic behaviors and UV spectra of the authentic compounds. The eleven batches of samples were classified as two clusters by hierarchical clustering analysis (HCA) and principle component analysis (PCA), and six samples were confirmed to establish the mutual model. The quality was assessed by similarity evaluation system for chromatographic fingerprint of TCM (2004B Version). The convenient and high specific method can be used to identify and evaluate the quality of the Ginseng Radix et Rhizoma.

AIM: To investigate the efficacy, safety and localization of multilayer amniotic membrane transplantation (AMT) for the management of corneal perforation associated with ulceration.METHODS: Six eyes (6 patients) were treated with multilayer AMT for corneal perforation associated with ulceration. The perforation size was 0.5-2mm in diameter. The amniotic membrane (AM) was applied to tamp the perforation, fill the ulcer and cover the surface of ulcer. The follow-up ranged from 5-19 months.RESULTS: The anterior chamber reformed at the first postoperative day in all patients, and kept in normal depth in the follow- up time. The epithelialization of the AM grafts was observed in about 3 weeks after surgery. During the first postoperative month, the corneal thickness at the perforation site gradually increased, and the stromal inflammatory cell invasions surrounding the corneal ulcer were gradually subsided.Two months postoperatively, the ulcer healed with scar with part neovascutarization; the corneal thickness of the ulcer area was stable and recovered almost normal. The vision was not improved in all patients after operation. During-follow up,no severe complications or recurrence of ulceration was noted.CONCLUSION: Multilayer AMT is an effective and safe method for the management of small corneal perforation associated with ulceration, but the ulcer healed with scar.

AIM: To evaluate the efficacy and safety of annular bubble conjunctival excision combining with amniotic membrane transplantation(AMT) for vernal keratoconjunctivitis(VKC) with gelatinous swellings(papillae) at the limbus.METHODS: Twenty eyes(10 patients) with VKC, were characterized by gelatinous swellings(papillae) at limbus and were underwent annular bubble conjunctival excision associated with AMT. The follow up ranged 5-21months.RESULTS: After operation, the symptoms were subsided remarkably: itching,discharge and foreign body sensation were almost disappear; photophobia and tearing were obvious in the first week after surgery, but were gradually alleviated, and almost disappear after one month of postoperative.Yellow-brown or filthy red gelatinous protuberances at limbus were cleaned away by operation and did not recur during the follow up. Corneal superficial punctuate keratitis(11 eyes) and corneal ulcers(3 eyes) were healed during the first week after surgery and did not recur. Conjunctival congestion was gradually lessened after surgery, which could not be noted 1months after surgery in 19 eyes, and the conjunctiva around the limbus, where AMT was performed, was whiter than the normal. But conjunctival congestion in 1 eye lasted for about 5mon accompanying with a little of itch, and this eye was treated with eyedrops with improvement but recurrence. No severe complications had been seen during the follow up.CONCLUSION: Annular bubble conjunctival excision combining with amniotic membrane transplantation is an effective and safe method for the treatment of vernal keratoconjunctivitis with gelatinous swellings (papillae) at limbus. But the candidates must be chosen with discretion.

AIM: To investigate the efficacy and safety of annular conjunctival excision combined with amniotic membrane transplantation for the management of earlier Mooren's ulcer.METHODS: Thirty eyes (24 patients) with earlier Mooren's ulcer were treated with this method, followed-up for 5-30mo. The characteristic of these patients was localized periphery corneal ulcer: the ulcer involved 30-120° corneal limbus with depth of 1/3-1/2 cornealthickness and width of 2-5mm.RESULTS: After surgery, symptoms subsided remarkably and immediately in all patients,and almost disappeared after stitches were removed. Corneal melts were controlled. At postoperative 2-3mo, the corneal thickness of the ulcer area became almost stable, which in some patients recovered normal and in others were still thinner than normal, and the average increase was about 1/3 of the corneal thickness. Corneal transparence and vision were improved. During follow-up, no severe complications or recurrence were noted.CONCLUSION: Conjunctival peritomy combined with amniotic membrane transplantation is an effective and safe method for the treatment of earlier Mooren's ulcer.
