AlM:To explore the clinical effects of using rigid gas permeable contact lens ( RGP ) for refractoriness amblyopia patients.
METHODS: Ninety - eight cases ( 98 eyes ) were voluntarily divided into RGP group and frame glasses group, and the two groups were received the regularity combined training to treat amblyopia for 6mo. We overviewed the corrected vision (on that day, 1, 3, 6mo) and the complication in RGP group .
RESULTS: The corrected vision in RGP group was obviously better than that in control group during the same time. The therapeutic efficacy in RGP group was better than that in frame glasses group, without serious complications at 6mo after treatment.
CONCLUSlON: RGP groups could get better corrected visual acuity. lt is safe and effective to improve corrected vision for refractoriness amblyopia patients.

0 05). No postoperative pyrexia and severe complications occurred in all the four groups. Conclusions The four procedures are all safe and feasible. The selection of these procedures is based on the patient’s individual conditions.

Lymphatic metastasis is one of the main routes of tumor metastasis. The limitation of traditional medicine in the treatment of lymphatic tumor metastasis lies in the low concentration of the drug in lymphatic metastases resulting in poor efficacy. Nanocarrier-based drug delivery system plays an important role in enhancing drug targeting, improving drug bioavailability, and reducing side effects. This review introduces the composition and function of the lymphatic system as well as its role in tumor metastasis, enumerates the present therapeutic means and limitations of anti-tumor lymphatic metastasis, and focuses on the recent advances in the passive, active and antigen-presenting cell-mediated lymphatic targeted drug delivery systems in tumor metastasis are highlighted.

Endocardial fibroelastosis(EFE) is a rare heart disease with a thickening of the endocardium by layers of collagenous and elastic fibres.Patients with EFE have diastolic and systolic heart failure.With the improvement of medicine,some progress has been achieved in EFE research.This article gave a comprehensive review to deepen the understanding of EFE.

Objective To analyze the cause of re-operation after radical cystectomy and ileal conduit in early follow-up period in order to improve the efficacy of this operation and reduce postoperative complications. Methods 12 cases from 81 cases of re-operation were studied retrospectively after radical cystectomy and ileal conduit for bladder tumor in early follow-up period.Of the 12 cases,there are 4 cases of T 4,8 cases of T 3,7 cases of G 2,5 cases of G 3.They are all transitional cell carcinoma. Results There were 4 cases of adhesive intestinal obstruction,2 necrosis of ileal conduit,2 adhesive folding of sigmoid colon into prostatic fossa,2 internal hernia and 2 avulsed incision due to infection .All the cases were re-operated nearly the first operation.After the second operation,all the cases were followed 6～12 months,average 7.7 months,the outcome was satisfied. Conclusions The ileal conduit is a kind of ideal methods for urinary diversion and its early complications should be avoided affecting the efficacy of this operation and the quality of life patients.

Objective To investigate the effect of edaravone pretreatment on myocardial injury induced by carbon dioxide pneumoperitoneum in patients undergoing laparoscopic gynecologic surgery.Methods Thirty patients undergoing laparoscopic gynecologic surgery,ASA Ⅰ or Ⅱ grade,were divided into two groups by random digits table with 15 cases each:control group and edaravone group.Edaravone group following tracheal intubation received vein infusion of edaravone 0.5 mg/kg,control group received equal volume of 0.9％ sodium chloride.The carbon dioxide pneumoperitoneum pressure was maintained at 10-15 mm Hg (1 mm Hg =0.133 kPa).Venous blood samples were collected before anesthesia induction and after operation 8 h for the measurement of the serum creatine kinase (CK),creatine kinase-MB (CK-MB),aspartate aminotransferase (AST) and lactate dehydrogenase (LDH).Results The serum levels of CK and AST were significantly higher after operation 8 h in control group than those of before anesthesia induction in control group and after operation 8 h in edaravone group [(205 ± 27) U/L vs.(123 ± 25) and (123 ± 29)U/L,(48±5) U/L vs.(34 ±3) and (36 ±5) U/L,P＜0.05].There was no significant difference in the serum levels of CK-MB and LDH between two groups and the group (P ＞ 0.05).Conclusion Pretreatment with edaravone 0.5 mg/kg can protect myocardium in patients undergoing laparoscopic gynecologic surgery.

Objective To investigate the role of mitochondrial permeability transition pore (mPTP) in attenuation of myocardial ischemia-reperfusion (I/R) injury by delayed preconditioning with sevoflurane in rats.Methods Eighty male SD rats, weighing 250-300 g, were randomly assigned into 5 groups ( n = 16 each): Ⅰsham operation group (group S), Ⅱ group I/R, Ⅲ sevoflurane delayed preconditioning group (group SP), Ⅳ the mPTP opener atractyloside + sevoflurane delayed preconditioning group (group A + SP), and Ⅴ atractyloside group (group A). Myocardial I/R was induced by ligation of anterior descending branch of left coronary artery for 30 min followed by 120 min of reperfusion in group I/R, SP, A + SP and A. In group SP and A + SP, 2.5%sevoflurane was inhaled for 1 h, while pure oxygen was inhaled for 1 h in the other groups, and then myocardial ischemia was performed 24 h later. In group A + SP and A, atractyloside 5 mg/kg was injected intravenously via caudal vein 15 min before ischemia. Blood samples were taken from carotid arteries for detection of serum cardiac troponin-Ⅰ (cTnI) concentrations at the end of reperfusion. Then the rats were sacrificed and hearts removed. The myocardial infarct size (IS) and expression of Bcl-2 and Bax in the myocardium were determined. Myocardial ultrastructure was examined with the electron microscope. Results Serum cTnI concentrations and Bax expression were significantly higher, the myocardial IS was significantly larger and Bcl-2 expression was significantly lower in the other groups than in group S ( P ＜ 0.05). Serum cTnI concentrations and Bax expression were significantly lower, the myocardial IS was significantly smaller and Bcl-2 expression was significantly higher in group SP than in group I/R ( P ＜ 0.05). Microscopic examination showed less damage in group SP than in group I/R. The protection provided by sevoflurane preconditioning was abolished by atractyloside. Conclusion Inhibition of mPTP opening can result in an up-regulation of Bcl-2 expression and down-regulation of Bax expression, which plays a role in attenuation of myocardial I/R injury by delayed preconditioning with sevoflurane in rats.
