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

21 mmHg.The side effects,IOP and application of anti-glaucoma drugs were examined 1 h,1 d,1 week,1 month,3 months and 6 months after SLT. Results The IOP was significantly decreased 1 week,1 month,3 months and 6 months after SLT compared with that before treatment(P21 mmHg using two anti-glaucoma drugs,respectively. Conclusion SLT is a safe and effective method for IOP control in early CPACG after treatment with laser peripheral iridoplasty and laser iridectomy.

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

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.

To optimize the pretreatment of Huanglian Jiedu decoction before ceramic membranes and verify the effect of different pretreatments in multiple model system existed in Chinese herb aqueous extract. The solution environment of Huanglian Jiedu decoction was adjusted by different pretreatments. The flux of microfiltration, transmittance of the ingredients and removal rate of common polymers were as indicators to study the effect of different solution environment It was found that flocculation had higher stable permeate flux, followed by vacuuming filtration and adjusting pH to 9. The removal rate of common polymers was comparatively high. The removal rate of protein was slightly lower than the simulated solution. The transmittance of index components were higher when adjust pH and flocculation. Membrane blocking resistance was the major factor in membrane fouling. Based on the above indicators, the effect of flocculation was comparatively significant, followed by adjusting pH to 9.
