·AIM: To evaluate the efficacy and safety of intravitreal triamcinolone acetonide(TA) as treatment for macular edema associated with retinal vein occlusion(RVO).·METHODS: The study group consisting 30 patients (30 eyes) with RVO combined with macular edema received intravitreal 4mg TA. Changes in best-corrected visual acuity (BCVA), intraocular pressure(IOP), examination with slit-lamp microscope, fluorescein angiography and optical coherence tomography(OCT) were observed during the follow-up. Statistical analysis was conducted with SPSS 12.0 software.·RESULTS: The visual acuity(VA) of all patients was significantly improved and the central macular thickness (CMT) was significantly relieved. There was no correlation between course, age, CMT before injection and the type of RVO. There was positive correlation between visual acuity before injection and after injection.·CONCLUSION: Intravitreal injection of TA is an easy-operated and safe therapy. After injection, macular edema can be rapidly relieved. VA at baseline is the predictor for the prognosis of VA. Some patients experience recurrence of macular edema between 3 to 6 months after injection.

AIM: To investigate the clinical effects of intravitreal Bevacizumab for 26 cases with retinopathy of prematurity (ROP) in Zone Ⅰ.
METHODS:A retrospective study. Totally 26 ROP infants between September 2013 and October 2014 diagnosed as high - risk ROP in Zone Ⅰ had been treated with intravitreal bevacizumab. They were divided into three groups, pre - threshold ROP, threshold ROP and acute posterior ROP ( APROP ). Postoperative effects were compared.
RESULTS:There were 26 infants (52 eyes) diagnosed as ROP in Zone Ⅰ, including 3 infants( 6 eyes) with pre -threshold ROP, 15 infants (30 eyes) with threshold ROP and 8 infants (16 eyes) with APROP. The first operation recovery rate of three groups respectively were 100% (6 /6), 60% ( 18 / 30 ) and 75% ( 12 / 16 ), which were not significantly different (P>0. 05).
CONCLUSION:Intravitreal bevacizumab for ROP in ZoneⅠ seems effective and has some advantages over conventional laser treatment, which could be first line treatment for high-risk ROP in Zone Ⅰ.

Objective To study the diagnosis and treatment of ch ildren with congenital choledochal cyst (CCC).Methods From Janu ary 1998 to January 2003, data from 43 cases children with CCC were used for thi s study. Their parameters included sex, age, diagnosis , types of CCC, time of surgery and style of surgery were retrospectively analyzed. Results The incidence of patients whose age under 2 years old was 72 %.The ratio o f gender (male:female) was 1:3. The children were examined by B-ultrasonic(B-u s),computed tomography(CT), and MRCP with the accuracy of 83.7 %, 78.9 % and 80. 0 % respectively.Forty cases underwent biliary reconstruction, cystectomy and Ro ux-en -Y bilioenteric anastomosis. There was no mortality, pre or postoperative compli cation. Conclusion B-us examination is the best method to diag nose the disease.Cystectomy and biliary reconstruction are effect to treat this disease.

Mandibular symphysis fracture combined with anteromedial dislocated condyle fracture is commom in clinical,but mandibular symphysis fracture associated with superolateral dislocation of the mandibular condyle is rare,which is often misdiagnosed or completely over-looked.Malpractice can lead to ankylosis and other sequelae.This article reviews 10 patients with mandibular symphysis fracture associated with superolateral dislocation of the mandibular condyle,discusses the causative mechanism,diagnostic features and clinical management according to literature data.

OBJECTIVE: To investigate the expressions of transforming growth factor beta1 (TGF-beta1) and bone morphogenetic protein-2 (BMP-2) in human mandible fracture callus and their quantity changes in the process of healing. METHOD: Thirty callus samples from the fractured mandible bone stumps were collected during operation, and two callus samples were collected from the angle-square jaw patients as controls. The expressions of TGF-beta1 and BMP-2 were test by the immunohistochemistry technic-SABC-staining in different periods of human fractured mandibular callus and in osseous tissue of normal angle of mandible. RESULT: The TGF-beta1 and BMP-2 were expressed in callus of different periods but not in normal bone tissue. The expression of TGF-beta1 increased slowly during the first three weeks after fracture and reached its maximum in the third week, and then weakened gradually. The expression of BMP-2 increased gradually during the first two weeks after fracture and reached its maximum in the second week, then the expression weakened gradually. CONCLUSION (1) BMP-2 may be one of the factors promoting the repair of fracture. (2) TGF-beta1 could be another signal pathway in repairment of fracture. (3) There could exist some synergistic effects between TGF-beta1 and BMP-2 in the process of fracture healing.

Objective To investigate the correlation between the formation of pigmented biliary calculus and biliary H.pylori infection.Methods Bile from 35 patients with pigmented biliary calculus and 10 healthy controls was cultured for aerobic,anaerobic and H.pylori.The expression of H.pylori- DNA in bile,bile duct mucosa and pigmented calculus were determined by PCR.The expression of H. pylori associated protein in bile duct mucosa was determined by Western-blot and Warthin-Starry staining.Results H.pylori culture was negative in all bile samples.In 35 patients with biliary pigmen- ted calculus,H.pylori was detected by PCR in the center of calculus,bile and bile duct mucosa of 14.29%,31.43% and 56.67% patients,respectively.Among H.pylori-DNA positive bile samples,7 contained anti-CagA antibodies,and 6 contained Vac A.in addition to Vacuolating cytotoxin(35000), glycoprotein(30000),Urase Band Urase A.Bacteria resembling H.pylori by Warthin-Starry stainning were found in 7 of 30(23.33%)bile duct mueosal samples from patients with biliary pigmented calculus. H.pylori-DNA and its associated protein were not detected in all bile and bile duct mucosae samples from the healthy controls.Conclusions The evidence of H.pylori-DNA and its associated protein in biliary system might indicate the role of H.pylori in the formation of biliary pigmented calculus.

AIM:To explore the inhibitive effects of cervical lymphadenectomy on kerstoplasy after alkaline burns.METHODS:The Wistar rats' corneas were transplanted into Sprague-Dawley(SD)rats' eyes which were randomly divided into 4 groups:group A(control group);group B,the cervicallymphadenectomy group;group C,corneal transplantation after the alkali burn injury;group D,cervical lymphadenectomy following group C.Out of 6 rats in each group,the cornea of one rat Was used for mawophage immunohistochemistry at day 14 after the transplantstion,and the remaining 5 rats were used for studying corneal immune rejection with a slit lamp.The time when allograft rejection occurred was recorded and mean survival times(MST)were compared among the groups.RESULTS:Compared with the MST of group A(10.40±1.14 days),the MST of group B(46.30±9.46 days)Was significantly longer(P＜0.05).MST of grafts between group C(7.00± 1.58 days)and group D(15.00±3.39 days)was also significant (P＜0.05).At 14th day after the transplantation,there was no CD68 immunoreactivity in the graft of group B,and CD68 proteins were expressed to some extent in the grafts of group A and D.However,in the graft of group C,the expression of proteins Was dramatically up-regulated.CONCLUSION:Cervical lymphadenectomy therapy has a significant effect in preventing corneal allograft rejection in normal and alkali burned oorneai beds.

This study was to evaluate the effect of individualized health education on blood glucose control in type 2 diabetic(T2D)Patients.Two hundred and thirty-eight T2D patients were randomly received individualized diabetes education(intervention group)or general education(control group).At 48 week,change of blood glucose control from baseline was observed.The blood glucose level and HbA1c in the intervention group were lower than those in the control group[(7.1±0.8)vs (9.3±6.5)mmol/L,(7.0 ±1.3)%vs(8.0%±1.0)%;P＜0.05].Thus,individualized diabetes education might be helpful for blood glucose control in T2D patients.
