?AlM:To evaluate the effect and safety of 1. 8mm coaxial microincision phacoemulsification - trabeculetomy with ultra-thin intraocular lens ( lOL ) implants for treating glaucoma complicated with cataract, and to compare with the traditional 3. 0mm small phacoemulsification-trabeculetomy with foldable lOL implantion.
?METHODS: ln this prospective study, 36 patients ( 36 eyes) with glaucoma and cataract in lnner Mongolia Autonomous Regian People’s Hospital were collected and randomly divided into 2 groups. For the small incision group: 18 cases ( 18 eyes ) underwent 3. 0mm coaxial incision phacoemulsification-trabeculetomy with foldable lOL implantion; ln th microincision group: 18 cases ( 18 eyes ) underwent 1. 8mm microincision phacoemulsification-trabeculetomy with ultra-thin lOL implantion. The two groups were recorded for 1wk, 1 and 3mo of visual acuity, corneal endothelial cell density, surgically induced astigmatism, intraocular pressure ( lOP ) , filtering bleb and complications. Pearson’s Chi-square test ande t-test were used to determine differences between the two groups.
?RESULTS:At 1wk postoperatively, visual acuity in the microincision group was better than that of small incision group, the difference was statistically significant ( P<0. 05). At 1 and 3mo, the difference in corrected visual acuity between the 2 groups had no significant difference (P>0. 05). At 1wk, 1 and 3mo, there was a significant different between the 2 groups in surgically induced astigmetism (P<0. 05). At 1wk postoperatively, there was a significant difference in corneal endothelial cells density between 2 groups (P<0. 05). But there were no significant difference at 1 and 3mo ( P > 0. 05 ). lOP reduced after surgy ( microincision group: 15. 26 ±3. 12mmHg, small incision group: 14. 57±2. 86mmHg), there was no significant difference between the 2 groups (P>0.05). There was no significant different between the 2 groups in blebs (P>0. 05). Neither iris injury, posterior capsule rupture nor anterior chamber bleeding complications was found in any groups.
?CONCLUSlON: TBy compared with traditional 3. 0mm coaxial small incision phacoemulsification -trabeculectomy with foldable lOL implantion, 1. 8mm microincision phacoemulsification-trabeculectomy withe ultra- thin lOL implantion can effectively reduce the astigmatism operation. This operation is safe, effective, convenient surgy for treating cataract and glaucoma.

Objective To assess the incidences of intrauterine growth restriction (IUGR) and extrauterine growth restriction(EUGR) in premature infants with respiratory distress syndrome (RDS) and early nutritional efficiency on EUGR.Methods Data of 70 infants with RDS admitted in neonatal intensive care unit were reviewed.According to the weight when a premature infant was discharged,all subjects were divided into EUGR group(48 cases) and non-EUGR group(22 cases).The difference of two groups in terms of basic situation,peripartum factors,nutritional support,treatment measures and complications were compared.Results Assessing by weight,the incidence of IUGR and EUGR was 12.86％ (9/70)and 60.00％ (42/70)respectively.The differences in birth weight [(1 666.10 ±440.16) g vs (2 108.20 ±552.81) g],head circumference at birth [(28.81 ± 2.65) cm vs (30.48 ± 2.39) cm],IUGR,multiple pregnancy (16 cases vs 3 cases),cesarean delivery (29 cases vs 7 cases) were considered statistically significant (P ＜ 0.05),and there were no stastitically significant difference in gestational age,nutritional support,mechanical ventilation and complications (P ＞ 0.05).Conclusion The EUGR is related with IUGR,multiple pregnancy,cesarean delivery,low birthweight,low birth head circumference.The short time nutrition interventions can't improve EUGR in RDS.

Lactate acid is an attractive biomarker reflecting microcirculatory dysfunction and tissue hypoxia.Surviving Sepsis Campaign in 2012 recommend lactate acid as one of the practical biomarkers representingtissue hypoxiato guide management of patients of septic shock.The Third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3) in 2016 updated septic shock clinical criteria as a vasopressor requirement to maintain a mean arterial pressure of 65mmHg(1mmHg=0.133kPa) or greater and serum lactate acid level greater than 2mmol/L(>18mg/dl) in the absence of hypovolemia.Lactate acid ≥4mmol/L is often associated with poor clinical outcomes in septic shock patients.Lactate-guided therapy is becoming increasingly important in guiding the resuscitation and the use of vasoactive agents of septic shock.Lactate clearance and early lactate area are valuable indicators to predict the prognosis in patients with septic shock.

AIM: To study the infiltration of polymorphonuclear neutrophils ( PMNs ) after conjunctival flap covering in alkali-burned cornea.
●METHODS: Rabbit cornea alkali-burned model was made, then 50 rabbits were randomly divided into the experimental group ( n=25 ) and the control group ( n=25 ) . At the same time the surgery of conjunctival flap covering was given to rabbits of the experimental group. The condition developing of alkali-burned cornea was observed by slit lamp biomicroscopy, and took photos in two groups. The infiltration of PMNs was identified by hematoxylin eosin ( HE) staining in different periods.
●RESULTS:The quantity of PMNs increased on the 3d, reached the lower level on 7d, shown a peak on the 14d, then decreased gradually. PMNs level of the experimental group was significantly lower than that in the control group, and the difference of 3, 14 and 21d was significant (P<0. 05).
●CONCLUSION: During the wound healing process, alkali - burned cornea has close relation with the infiltration of PMNs. The treatment of conjunctival flap covering for the severe alkali-burned cornea was found to have good effect.

BACKGROUND: The shear bond strength between ceramic orthodontic brackets and teeth is so large that ceramic brackets are not easily eliminated safely. Whether the shear bond strength of self-etching primer/adhesive can be decreased and the injuries to enamel can be reduced has been always concerned by orthodontists. OBJECTIVE: To evaluate the bond strength between self-etching primer/adhesive system and ceramic orthodontic brackets and make a comparison with Jingjin enamel adhesive most commonly used by clinicians in China.DESIGN, TIME AND SETTING: Controlled observation, performed at Hebei University of Science and Technology in March 2006.MATERIALS: Twenty permanent premolars extracted due to orthodontic treatment were selected. The premolars were required to have excellent enamel and gloss, no cracks or carious lesions, and have not been given any chemotherapy. Ceramic orthodontic brackets were arch wire ceramic premolar brackets with 0.022-inch standard edgewide (3M company,USA). The bottom bracket area was 12.16 mm2. Self-etching sealant and TransbondTM fight-cure adhesive were purchased from 3M company, USA. Jingjin enamel adhesive, a conventional self-etching adhesive, was provided by Tianjin Institute of Synthetic Materials Industry, China.METHODS: The 20 premolars were randomly evenly divided into a self-etching primer/adhesive group, in which,self-etching sealant and TransbondTM fight-cure adhesive were applied, and a Jingiin enamel adhesive group, in which,Jingjin enamel adhesive was used.MAIN OUTCOME MEASURES: After 24 hours, shear bond strength was determined respectively in the two groups using anti-shearing testing machine. Simultaneously, residual adhesive remaining on the teeth was examined. RESULTS: The mean shear bond strength was lower in the self-etching primer/adhesive group than in the Jingjin enamel adhesive group, but there was no significant difference (P > 0.05). The mean shear bond strength in the two groups was clinically acceptable. The residual adhesive remaining on the teeth was significantly less in the self-etching prime/adhesive group than in the Jingjin enamel adhesive group (P < 0.01).CONCLUSION: Self-etching prime/adhesive system used for bonding ceramic orthodontic brackets can satisfy clinical requirements. Moreover, its bond strength can be appropriately decreased and ceramic brackets are easily removed, thereby,injuries to enamel can be reduced.
