Objective To evaluate the therapeutic effects of needling revision with mitomycin C(MMC) subconjuctival injection on early failed filtering blebs after trabeculectomy for glaucoma. Methods Needling revision with MMC 0.2 mL(0.04 mg) subconjuctival injection was performed on 86 eyes of 76 patients with failed filtering blebs 2 to 6 weeks after trabeculectomy for glaucoma.An average of 1.88 times of treatment was performed.The intraocular pressure(IOP),blebs and side effects were observed,and follow-up was conducted for 6 months. Results Two to six weeks after trabeculectomy,there were 50 eyes with thickened and focalized blebs,32 eyes with encapsulated blebs and 4 eyes with no bleb.Six months after needling revision with MMC subconjuctival injection,blebs of 61 eyes turned into functional ones.The blebs were thinned and multicysted in 24 eyes,diffused and elevated in 37 eyes,thickened and focalized in 6 eyes,encapsulated in 13 eyes and disappeared in 6 eyes.Three months after treatment,the mean IOP was(15.2?6.1) mmHg,and there were 57 eyes with IOP

To investigate the protective effects and possible mechanism of Mycelium of Hirsutella hepiali Chen et Shen (MHCS) on metabolic syndromes, free fatty acid and MHCS-treated hepatocytes were used for detecting autophagy-related LC3, p62 and lipid accumulation. Moreover, high fat diet fed mice were used to establish metabolic syndromes model. 50-weeks age mice were randomly divided into: control group, model group and MHCS group. At 80-weeks age, 15 mice were randomly chosen from each group separately for examining oral glucose tolerance, serum insulin, insulin-like growth factor 1 (IGF-1), hepatic LC3, p62, p-NF-kappaB p65, NF-kappaB p65, IL-6 and CXCL-8. Moreover, insulin resistance index (IRI) was calculated. Hepatic pathological changes, including vacuoles, lipids accumulation and fibrosis were observed. Remaining mice were fed with diet separately to 110 weeks-age for statistics of mortality. MHCS promoted autophagy of free fatty acid treated hepatocytes. Mice fed with high fat plus MHCS diet exhibited improved oral glucose tolerance, insulin resistance, hepatic pathology, inflammation, mortality and activated autophagy. The protective effects of MHCS against metabolic syndroms might be through the activation of hepatic autophagy.

AIM: To quantitatively investigate transforming growth factor-β(TGF-β) and its receptors in normal bulbar conjunctival tissues and pterygium tissues. METHODS: Thirty cases of pterygium patients were randomly selected to undergo surgical resection of pterygium lesion, and the normal margin of bulbar con-junctival tissues were collected as control. Gene expres-sion was detected quantitatively by the method of quantitative real-time PCR (QRT-PCR) analysis. RESULTS: The expression level of TGF-β1 and TGF-β2 was 4.26×10-7±1.45×10-7 and 1.08×10-10±0.68×10-10 in normal bulbar conjunctival tissues, while 10.67×10-7±7.47×10-7 and 8.23×10-11±6.63×10-11 in pterygium tissues. The expression level of TGF-βRⅠand TGF-βRⅡwas 0.003015±0.0036 and 5.33×10-5±5.05×10-5in normal bulbar conjunctival tissues, while 0.000379±0.000281 and 1.002×10-5±9.04×10-6 in pterygium tissues. The expression level of TGF-β1 and TGF-β2 in pterygium was elevated (P<0.01). TGF-β1 expression level in pterygium increase 2.9±2.8 times than in normal conjunctiva. TGF-β2 expression level in pterygium increase 7.5±1.4 times than in normal conjunctiva. The expression level of TGF-βRⅠin pterygium was significantly lower (P<0.05). The expression level of TGF-βRII in pterygium was significantly lower (P<0.01). CONCLUSION: QRT-PCR is an effective method to quantitatively detect gene expression in eye. The upregulation of TGF-β1 and TGF-β2 and downregulation of their receptors expression may play an important role in the pathogenesis of pterygium, which is noteworthy further investigation in diagnosis and treatment of pterygium.real-time PCR; gene expression

In this study, solvent evaporation method was used to preparing baicalin ethylcellulose microspheres for intranasal administration. The prepared microspheres were round with certain rough surface. The average drug loading and entrapment efficiency was (33. 31 ± 0. 045)% , (63. 34 ± 0. 11)% , respectively. As the characteristic crystalline peaks of baicalin were observed in the microspheres sample, the result of X-ray diffractometric analysis indicated that the baicalin was present in crystalline form after its entrapment in ethylcellulose matrix. By investigating the thermogram of microspheres sample, it was found that endothermic peak of baicalin was shifted from 211. 8 °C to 244. 2 °C and associated with the first broad endothermic peak of ethylcellulose. This could confirm that baicalin was loaded into ethylcellulose, nor simply physical mixture. The powder flowability test exhibited that the specific energy of microspheres was 3. 57 mJ . g-1 and the pressure drop was 2. 22 mBar when air kept the speed of 2 mm . s-1 through the powder bed with the force was 15 kPa. The consequence of the baicalin in vitro released from microspheres showed that the pure baicalin sample displayed faster (90%) release than microspheres sample (75%) in 7 h. Fitting model for release curve before 7 h, the results showed that the pure baicalin sample and the microsphere sample accorded with first order model (R2 = 0. 990 4) and Riger-Peppas model(R2 = 0. 961 2), respectively. Ex vivo rabbit nasal mucosa permeability experiment revealed that the value of cumulative release rate per unit area of the microsphere sample was 1. 56 times that of the pure baicalin sample. This provided the foundation for the in vivo pharmacokinetic study.

ObjectiveTo evaluate the efficacy of mini-incisional double-tsuge suture method with 0-0 absorbable polydioxanone-cord (PDS-Ⅱ)in repair of acute achilles tendon rupture.MethodsA total of 34 patients were subjected to acute closed achilles tendon ruptures,including 25 males and 9 females at a mean age of 32 years ( range,20-45 years).Injury causes included sports injuries in 27 patients,falling injuries in six and heavy object impingement injury in one.The time from injury to operation was average 3 days (range,1-6 days).All patients underwent minimally invasive repair with double-tsuge suture method by using PDS-Ⅱ.The ankle joint was fixed with short leg plaster cast at 30° plantar flexion position and the cast was removed six weeks later to take functional exercise.The patients could walk with full weight-bearing 8-10 weeks later and could gradually return to activity 3-4 months later.Results There was one patient with poor incision healing and one patient with reflex sympathetic dystrophy postoperatively.The rest patients had stage Ⅰ incision healing without skin adhesions.No complications such as infection,lower extremity deep venous thrombosis or sural nerve injury occurred postoperatively.All the patients received follow-up of 12-24 months (average 15 months),which showed no complications like tendon rerupture occurred.According to clinical evaluation criterion of Termann,the average score was 92 points (range,76-96 points).The result was excellent in 28 patients,good in five and fair in one,with excellence rate of 97％.ConclusionsSmall incisional double-tsuge suture method achieves low rate of complications and good outcomes for repairing acute achilles tendon rupture and is an ideal tendon surgery approach.

Objective To investigate mechanisms underlying the prevention of experimental autoimmune encephalomyelitis (EAE) in mice by intraperitoneal infusion of myelin oligodendrocyte glycoprotein 35-55 (MOG35-55) (MOG i.p.).Methods C57BL/6 mice were immunized with MOG35-55 to establish the model of EAE and then were intraperitoneally injected daily with MOG35-55 or ovalbumin (OVA, served as control) from day 6 to day 16.EAE was evaluated daily using a general clinical scoring system and histological analysis.Numbers of lymphocytes in peripheral blood and central nervous system (CNS) were detected at different time points.Effects of MOG i.p.on the migration of MOG-T cells in vivo were analyzed by an adoptive transfer experiment.Maturation of splenic antigen-presenting cells (APCs) and migration of MOG-T cells in vitro were examined by fluorescence activated cell sorting (FACS) and a Transwell system, respectively.Results MOG i.p.protected the mice from development of EAE by blocking the lymphocyte recruitment to CNS.More effector T cells were trapped in the periphery of EAE and naive mice in adoptive transfer experiment after MOG i.p.treatment.MOG i.p.induced the maturation of splenic APCs and enhanced the expression of CD80, CD86 and major histocompatibility complex class Ⅱ (MHCⅡ) molecules.Mature APCs blocked the recruitment of effector T cells to CNS.Conclusion MOG i.p.protects mice from EAE by inducing the maturation of splenic APCs.
