Chinese Journal of Experimental Ophthalmology 2015;33(5):474-477
Herpes simplex keratitis (HSK) is the first inflammatory cause for uniocular blindness.The clinical inspection methods commonly used are limited to general observation,while in vivo confocal microscopy (IVCM) can provide details of cellular changes in an intravital HSK.IVCM not only gives more clinical evidence for pathology studying of HSK,but also serves as a new technology for the whole progress of HSK epidemiology.This article reviewed current researches of applying IVCM for HSK clinical observation and summarized these latest results.Morphological changes of each layer of the cornea,the specificity of these changes and clinical application of IVCM had been discussed in this article.
2.Induction of mice spleen suppressor cell activity by Trypterygium Wilfordii Hook f
Chinese Journal of Pathophysiology 1986;0(02):-
We have studied the induction of mice spleen suppressor cell activity by Trypterygium Wilfordii Hook f. both in vivo and in vitro. We detected the suppressor cell activity in mice which were administrated with the drug for different days & found that after giving the drug for 5 or 9 days, the suppressor cell activity elevated remarkly, but for 12 & 15 days, the suppressor cell activity varied indefinitely, some were higher & some were lower. The drug inhibited the response of spleen cell to Con A too. But the release of inhibition on Con A responsibility was earlier than the recovery of elevated suppressor cell activity. Cocultured with the drug, slight promotion on cell proliferation was observed. The normal spleen cells cocultured with the drug for two days suppressed the normal spleen cell proliferation stimulated by Con A, the suppressive rate was comparable to that of Con A induced suppressor celll.

4.Asymmetric dimethylarginine and diabetes with cerebrovascular diseases
International Journal of Cerebrovascular Diseases 2010;18(6):450-455
Nitric oxide (NO) is the most important known endogenous vasodilator factor. The competitive inhibitor asymmetric dimethylarginine (ADMA) of endothelial nitric oxide synthase (NOS) inhibits NO synthesis, which makes NO/NOS pathway to be obstructed and the reduction of NO synthesis. The studies in recent years have suggested that ADMA is as-sociated with the occurrence and development of diabetes with cerebrovascular disease. It has provided new insights into further clarifying the mechanism of the disease.

Conclusion:Radiofrequency hyperthermia ablation combined with chemotherapy in treatment of advanced non small cell lung cancer and metastatic lung cancer clinical effect is obvious.
8.Expression of adiponectin in the periodontal tissue of Kunming mice with diabetic periodontitis
Chinese Journal of Tissue Engineering Research 2015;(5):721-726
BACKGROUND:Adiponectin and periodontal disease are closely related with type 2 diabetes. OBJECTIVE:To detect the expression of adiponectin in periodontal tissue of Kunming mice of diabetes periodontitis, and explore the effects on periodontal tissue pathology and prognosis. METHODS:Sixty 3-week-old Kunming mice were divided into three groups according to the different modeling methods:control group (normal feeding), diabetes group (diabetic model was established by injection of al oxan), diabetes and periodontitis group (periodontitis model was established by local ligation and bacteria developed). Each group contained 20 rats. RESULTS AND CONCLUSION:At 20 days after modeling, the blood glucose, fasting insulin and insulin resistance index of mice in the diabetes group were higher than that in the control group (P<0.05). ELISA, RT-PCR and western blot analysis results showed that, adiponectin gene and protein expression levels in periodontal tissues were the highest in the control group, then in the diabetes group, and the lowest in the diabetes and periodontitis group, at 1, 3, 6, months postoperatively, respectively (P<0.05). The periodontal gum tissue inflammation and histopathological changes were observed at 1, 3, 6, months postoperatively. The results showed that, the inflammation in periodontal tissues was the most obvious in the diabetes and periodontitis group, and was visible in the diabetes group, but the inflammation was not present in the control group. Experimental findings indicate that, the down-regulation of adiponectin expression in the periodontal tissue is one of the important factors that trigger and aggravate the onset of periodontitis.
9.Insulin-like growth factor-1/chitosan/collagen composite scaffold and the proliferation of human periodontal ligament cells
Chinese Journal of Tissue Engineering Research 2014;(8):1231-1236
BACKGROUND:Insulin-like growth factor-1 can promote mitosis of fibroblasts as wel as periodontal cellgrowth, differentiation and synthesis of extracelular matrix.
OBJECTIVE: To observe the effects of chitosan/colagen composite scaffold carrying insulin-like growth factor-1 on proliferation of human periodontal ligament cels.
METHODS: The human periodontal ligament cels were seeded on chitosan/colagen composite scaffold carrying insulin-like growth factor-1 and ordinary colagen scaffold. The release of recombinant human transforming growth factor-β1 was detected at 1, 24 hours and 1 week after culture; celladhesion and proliferation were detected at days 1, 7 and 28.
RESULTS AND CONCLUSION:The release rate of recombinant human transforming growth factor-β1 in the composite scaffold was significantly lower than that in the ordinary colagen scaffold at 1, 24 hours and 1 week after cellseeding (P < 0.01). The celladhesion and proliferation showed no difference between two groups at day 1 after cellseeding, but became significantly higher in the composite scaffold than that in the ordinary colagen scaffold at days 7 and 28 (P < 0.01). These findings indicate that chitosan/colagen composite scaffold carrying insulin-like growth factor-1 can significantly promote the proliferation of the human periodontal ligament cels.
