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

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

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.

PurposeTo investigate the relationship between left atrial volume index (LAVI) and severity of coronary lesions in patients with stable angina pectoris, so as to provide information for the evaluation of the severity of coronary artery disease (CAD). Materials and MethodsAccording to the results of coronary angiography, 279 patients with stable angina pectoris and 92 healthy people were as control group, all subjects were divided into four groups: control group (n=92), single-vessel CAD group (n=116), double-vessel CAD group (n=93) and triple-vessel group (n=70). Each group was compared in the aspects of demographic characteristics, history of illness, liver and kidney functions and parameter's difference in echocardiogram; the correlation between LAVI and Gensini score was analyzed; and the receiver operating characteristic (ROC) curve was used to identify the predictive value of LAVI in severity of coronary lesions.ResultsCompared with the control group, the double-vessel and triple-vessel CAD groups had significantly larger left atrial diameter (P<0.05). In triple-vessel CAD group, the left atrial diameter was significantly larger than that in the single-vessel CAD group (P<0.05), and the left ventricular end-diastolic diameter was significantly larger than that in the control group and in the single-vessel CAD group (P<0.05), and the E/Em and LVMI were significantly higher than those in other groups (P<0.05). The LAVI was higher in patients with CAD compared with those in the control group and the LAVI in the triple-vessel CAD group was significantly higher than that in single-vessel CAD group and double-vessel CAD group (P<0.05); the LAVI was correlated positively with Gensini score (r=0.499,P<0.01). LAVI had certain value in predicting triple-vessel CAD (AUC=0.782,P<0.01). The results of multi-factor Logistic regression analysis showed that male patients with hypertension, mitral reflux, and multi-vessel CAD were more likely to had high LAVI.Conclusion The worsening LV diastolic function is associated with the increasing severity of coronary artery lesions, and LAVI may have predictive value for severity of CAD.

Objective To evaluate the efficacy of MRI-detected extramural venous invasion (mrEMVI) in predicting tumor responses to preoperative chemoradiatiotherapy (pre-CRT) in patients with locally advanced rectal cancer (LARC).Methods The clinicopathological data,tumor response and mrEMVI information of 47 LARC from February 2013 to December 2014 were retrospectively collected.mrEMVI was given 0-4 score according to the degree,3-4 score were defined as mrEMVI positive;patients with mrEMVI positive were divided into three subgroups according to vascular size (large,middle and small).Association between different mrEMVI subgroup and tumor response was analyzed using Fisher exact test.Result 26 patients were mrEMVI positive.18 and 8 patients scored 3 and 4 for mrEMVI positive,respectively;16,6 and 4 patients were small,middle and larger vessels of mrEMVI positive,respectively.Patients with mrEMVI positive had less TRG 0-1 than mrEMVI negative (P =0.019).Scored 4 and larger vessel of mrEMVI positive had less TRG 0-1 than mrEMVI negative (P =0.038 and 0.017).Conclusions mrEMVI positive score 4 or larger vessel predict poor tumor response to pre-CRT in patients of locally advanced rectal cancer.

An immunopotentiating compound has been isolated from the metabolites of Bacillus mycoides under the bioassay-guided isolation and identification for its immunopotentiating effect and chemical structure. The isolation and purification of the compound were consisted of macroporous adsorptive resins, silicagel chromatographic column and Sephadex G-200 chromatographic column. The immunopotentiating effect was assayed in every step isolation. At last, the only substance having the strongest immunopotentiating effect had been isolated and purified. Through the procedure consisiting of Ultra-Violet spectroscopy (UV), IR (Infrared Radiation), Time of Flight Mass Spectrum (TOF-MS), Nuclear Magnetic Resonance (NMR) and Element analysis, the possible structure of compound M had been identified as cyclic (Pro-Gly) dipeptide (C7H10O2N2) (Diketopiperazine). To be determined the immunopotentiating effect, the mice were treated by intraperitoneal injection of cyclic (Pro-Gly) dipeptide in the treatment group and physiologic saline in the control group. At the 14th day after the injection, the SOD activity and the phagocytosis activities reached the peak value and were significantly higher than those in control group. At the 21st day, the bactericidal activity reached peak value and was significantly higher than that in the control group. From the above results, we concluded that the main active component enhancing the immunity of mice was cyclic (Pro-Gly) dipeptide in the metabolism of Bacillus mycoides.
