Recent Advances in Ophthalmology 2001;21(3):174-176
Objective To observe the effects and explore the mechanism of orthopia by using viscoelastic substance (sodium hyaluronate)in adherent strabismus(AS).Methods A total of 29 cases(33 eyes)of AS which were caused by various factors were performed strabotomy,in which sodium hyaluronate was poured into cap tenon space and /or around ocular muscles in which preserved after operation.Ocular movement was requested in 12~24 hours post-operation lest ocular muscles adhered to other tissues again.The main index we observed were the effectiveness of strabotomy and ocular movement.Results All 33 eyes achieved good results:17 eyes(51.5%) were cured,26 eyes(78.8%) obtained distinct improvement(DI). The operative results have reference to the cause of adherent strabismus,period of muscular adherence and visual function post-operation.No complications were found.Conclusion Our observation support that sodium hyaluronate can prevent ocular muscles from re-adhering to other tissues around after strabotomy.Most of the patients can obtain better effects by this viscoelastic therapy.
6.Research Progress of a Novel Pro-apoptosis Gene PNAS-4 in Gene Therapy and Its Molecular Mechanism Hypotheses.
Journal of Biomedical Engineering 2015;32(6):1380-1384
PNAS-4 is a novel pro-apoptosis gene identified latetly. In recent years, there has been a large number of research reports on the basic studies about PNAS-4 in cancer gene therapy and gene therapy of PNAS-4 alone or combined with chemotherapy or radiotherapy manifested a good application prospect, but its molecular mechanisms to promote apoptosis is not clear yet. In this paper, recent research about PNAS-4 in cancer gene therapy is briefly reviewed, and recent hypotheses on its molecular mechanisms to promote apoptosis are especially elucidated. Based on its newly identified characteristics of structural domain, we made a point that PNAS-4 might regulate functions of some target protein related to apoptosis by deSumoylation as a new deSumoylating isopeptidase, and consequently promote apoptosis.

7.The roles of lipoprotein-associated phospholipase A2 in carotid artery atherosclerosis and ischemic stroke
International Journal of Cerebrovascular Diseases 2010;18(4):282-285
The lipoprotein-associated phospholipase A2 (Lp-PLA2), a subtype of the phospholipase A2 superfamily, is produced primarily by macrophages and lymphocytes. Lp-PLA2specifically hydrolyzes oxidized phospholipids on oxidized low-density lipoprotein particles,resulting in production of lysophosphatidylcholine and oxidized fatty acids. Lp-PLA2 is expressed in atherosclerotic plaques and in macrophages within a fibrous cap of unstable plaque.Studies haw shown that the plasma Lp-PLA2 activity increases significantly in patients with ischemic stroke, and Lp-PLA2 may become an independent risk factor for predicting ischemic cerebrovascular events. The selective Lp-PLA2 inhibitor can reduce the inflammatory response,enhance the stability of plaques, and inhibit the formation of atherosclerotic plaques, and may become a new class of drugs for preventing the formation of atherosclerotic plaques.
8.A meta-analysis of hemoglobin target for anemia of patients with chronic kidney disease
Chinese Journal of Nephrology 2012;(10):775-779
Objective To explore the role of hemoglobin (Hb) level in mortality and morbidity of chronic kidney disease (CKD)patients,aiming to give some evidence for therapy of anemia.Methods Randomized,clinical trials (RCTs) were identified by searching Medline,Embase and the Cochrane library.All the analyses were performed using the Revman software available free from the Cochrane collaboration.Results Twenty-three trials involving 10 204 patients were identified.Overall,the high Hb target was associated with increased risk of all-cause mortality (RR=1.10,95% CI 1.00 to 1.21),hypertension (RR=1.40,95% CI 1.12 to 1.75),stroke and hospitalization (RR=1.07,95% CI 1.00 to 1.14) compared with low Hb target (P<0.05).No significant difference was found in the risks of non-fatal mycardial infarction (RR=1.13,95% CI 0.79 to 1.62) and renal replacement therapy (RR =1.00,95% CI 0.85 to 1.18).Conclusions Targeting low Hb target is beneficial to CKD patients based on reduced risk of hypertension,hospitalization,stroke and all-cause mortality.However,no significant difference is found in non-fatal mycardial infarction and renal replacement therapy.

10.Progress and hot spots of comprehensive treatment for primary liver cancer
Chinese Journal of Digestive Surgery 2021;20(2):163-170
The treatment principle for primary liver cancer referring as hepatocellular carcinoma (HCC) in this article is comprehensive treatment based on radical hepatectomy. Focusing on improving the resection rate and reducing the recurrence rate after operation, the conversion therapy, preoperative neoadjuvant therapy and postoperative adjuvant therapy have emerged to become potentially curative strategies and research hotspots. HCC is highly invasive and often complicated with cirrhosis, so comprehensive treatment is essential for better prognosis. However, due to the controversy of surgical indications and heterogeneity among individuals, the concepts and treatment methods of above three therapies, especially between the conversion therapy and the preoperative neoadjuvant therapy, remain overlap and puzzle sometimes. Moreover, because of the different therapy goals, the above three therapies are different in the selection of treatment methods, duration of therapy and evaluation criteria. Based on clinical practice, the authors investigate the progress and hot spots of the conversion therapy, preoperative neoadjuvant therapy and post-operative adjuvant therapy of HCC, expecting more clinical evidence-based medicine to standardize the development of comprehensive treatment, so as to become a breakthrough to improve the diagnosis and treatment of HCC.
