Objective To study the mechanism of haze formation after photorefractive keratectomy (PRK). Methods 27 adult New Zealand white rabbits were employed in this study.24 of them received PRK in the right eye and laser in situ keratomileusis (LASIK) in the left eye at the same time and under the same condition for -10\^00D ablation at once,24hour,1 week,2 week,1month,3 month,6 month and 12 month after surgery,the corneas were examined periodically by slip\|lamp microscopy for haze formation,and the both eyes of 3 rabbits were enucleated,the corneas were studies with light microscopy;transmission electron microscopy;immunohistochemical evaluation for extracellular matrix,including collagen type Ⅰ,type Ⅲ,type Ⅵ,cellular fibronection,tenascin and laminin;RT\|PCR detection for mRAN of collagen type Ⅰ. Results The incidence of haze was 100% after PRK.No haze formation after LASIK.Haze was located at the anterior stroma immediately adjacent to the ablated areas.The change of structure and composition which correlated with haze formation was due to a combination of the following factors:the basement membrane of corneal epithelium was discontinuous;A new layer of subepithelium tissue was synthesized;fibroblast was increased in number and activated;the collagen fibrils were disorganized.The diameter of fibrils and the space between the fibrils were irregular in the anterior stroma;The newly synthesized extracellular matrix inculding collagen type Ⅰ,type Ⅲ,type Ⅵ,cellular fibronection,tenascin and laminin were deposited in the anterior corneal stroma.Conclusion\ The formation and disappearing of haze was the result of interreaction between fibroblast and extracellular matrix.The destruction of basement membrane of corneal epithelium and Bowmen's member after PRK is initializing factor during haze formation.\;[

Objective To observe the relation between functions of vessels of lower extremities and TCM syndromes differentiation in diabetes patients. Methods Totally 168 diabetics of Type II were differentiated into 5 syndromes, i.e. 29 cases of yin deficiency with excessive heat, 41 cases of qi and yin deficiency, 30 cases of yin and yang deficiency, 37 cases of blood stasis in channels, and 31 cases of damp heat affecting the spleen, and 26 healthy people were involved in the control group. The peripheral vessel diagnostic system was adopted to get the toe photoplethysmogram (PPG) and ankle brachial index (ABI) to observe the blood perfusion of limb terminals and the functional state of lower limb arteries. The relation between function of vessels of lower extremities and TCM syndrome was analyzed. Results All the diabetic groups were related with the arterial blood supply of toe terminals. Diabetes was the main risk factor in affecting the terminal blood supply (P

0.05). Conclusion The sinus node arteries can generally be found by angiography. There is no significant relationship between coronary artery diseases of sinus node and sick sinus syndrome.

Objective To evaluate the value of echocardiography in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Methods The eehoeardiographie results of five patients with isolated anomalous origin of right pulmonary artery from ascending aorta were reviewed retrospectively. Results Severe pulmonary hypertension occurred in all the patients,besides accompanied with patent duetus arterious, no other congenital malformations combined. Three patients underwent operation. Patent ductus arterious was missed in one patient's diagnosis. Another patient was missed isolated anomalous origin of right pulmonary artery from ascending aorta in several echoeardiographic examinations, once misdiagnosed as complete transposition of the great arteries. Conclusions There are many anatomic and hemodynamic similarities in patients with isolated anomalous origin of right pulmonary artery from ascending aorta. Grasping their common charaeters and exploring multi-position and multi-section are helpful to make correct diagnosis.

AlM:To compare the efficacy and complication of extra-trabeculotomy in combination with trabeculectomy and trabeculectomy and compound trabeculectomy in the treatment of primary infantile glaucoma.
METHODS: Patients with primary infantile glaucoma undergone one of the three procedures from Jan 2006 to Jan 2014 were selected. Among them, group A ( 20 patients, 31 eyes ) underwent extra- trabeculotomy in combination with trabeculectomy, group B ( 20 patients, 32 eyes ) underwent trabeculectomy, while group C ( 20 patients, 30 eyes) underwent compound trabeculectomyRESULTS:The success rates in group A were 96. 8% at the time of discharge and 90. 3% during follow-up (mean 24mo) ; the rates in group B were 96. 9% and 81. 2%( mean 24mo) the rates in group C were 83. 3% and 76. 7%( mean 24mo ) respectively, the differences being significant (P <0. 05). ln group A and group B, there was no severe complications, while in group C, one case had vitreous prolapse.
CONCLUSlON: Extra - trabeculotomy in combination with trabeculectomy is more efficacious and safer than trabeculectomy and compound trabeculectomy in the treatment of primary infantile glaucoma. lt should be the first choice for primary infantile glaucoma.

Objective To observe the clinical efficacy and safety of low-dose tacrolimus (TAC) combined with tripterygium(TW) in treatment of steroid-resistant nephrotic syndrome (SRNS). Methods The patients, who were diagnosed with mesangial proliferative glomerulonephritis (MesPGN) and focal segmental glomerulosclerosis (FSGS) by biopsy and failed to respond to a 3 month treatment with prednisone (1 mg/[kg • d], maximum 60 mg/d, were randomly divided into 2 groups (TAC+TW group and TW group). Initially TAC+TW group took TAC 0. 05 mg/(kg • d) 2 h after meal at a 12 h interval; the plasma TAC level was examined after 3 days and was kept at 1. 5-4 ng/ml; meanwhile, TW was given at 60 mg/d before meal. TW group only took TW(60 mg/d before meal). The efficacy, adverse reactions and plasma TAC levels were observed in each group. Results (1) Totally 20 patients met the recruitment criteria, including 11 in the TAC+TW group and 9 in the TW group. The age, sex, time of onset, blood pressure, 24 h urine protein, serum albumin, creatinine, cholesterol, triglyceride, fasting blood glucose, renal pathology types and period of prednisone use were similar between the two groups. (2) In TAC+ TW group the urine protein began to decrease one month later; 12 months later,8 cases had complete remission (72. 7%), 2 had partial remission (18. 2%),and 1 was ineffective (9. 1%), with a total effective rate of 90. 9%. I n TW group the urine protein also began to decrease one month later; 12 months later only 2 cases had complete remission (22. 2%), 4 had partial remission (44. 5%), and 3 were ineffective (33. 3%), with a total effective rate of 66. 7%. (3)In TAC + TW group the plasma protein was significantly higher than that before treatment; the plasma protein recovered to normal level after 6 month treatment. However, there was no significant increase in TW group. The pre- and post-treatment serum creatinine levels were similar between the two groups. (4) The incidence rates of adverse reactions were not significantly different between the two groups. Conclusion Low dose TAC combined with TW can effectively decrease proteinuria in patients with SRNS, generating a higher rate of clinical remission; meanwhile, the patients have a good tolerance and less adverse reactions.

Objective To investigate the possible risk factors for lead poisoning in order to prevent the lead poisoning in children.Methods One thousand and fifty-five children aged 5 months to 16 years who were outpatients in Beijing children′s hospital were chosen. Blood lead was analyzed by 3010-B lead analyzer for each child.Also the risk factors were recorded by using a standardized questionnaire.Results The mean level of blood lead was(110.1?41.9) ?g/L with the occurrence of lead poisoning (blood lead ≥100 ?g/L) at 43.51%.No difference were found in blood lead level among different age groups.Several environmental and social factors were found to be related to lead poisoning in children,such as non-balanced diet,rarely hand washing,frequent eating crisp foods,not frequency of calcium and zinc supplementation and frequency of room decoration.Conclusion Unhealthy dietary and life styles contribute to lead poisoning in children.
