Objective To investigate the protection and mechanism of procyanidins (PC) against H2O2 induced oxidative damage of human trabecular meshwork cells (HTMC) in order to provide an experimental foundation for glaucoma clinical treatment.Methods HTMC were cultured and then divided randomly into 5 groups.As untreated group:Normal cultured HTMC;Control group:Normal cultured HTMC + H2O2 (500 μmol · L-1 for 1 hour);Treated group:Normal cultured HTMC + H2O2 (500 μmol ·L-1 for 1 hour) + PC (PC fmal concentrations were 0.02 g · L-1,0.05 g · L-1,0.10 g· L-1).Real-time fluorescence quantitative polymerase chain reaction (PCR) was used to investigate the expression of mitochondrial complex Ⅰ mRNA.Results Compared with untreated group (1.000 0 ± 0.000 0),the differences of mitochondrial complexⅠ mRNA expression in 0.02 g · L-1 PC (0.401 3 ±0.010 3),0.05 g · L-1 PC (0.791 5 ± 0.008 5) groups were statistically significant (all P ＜ 0.01),but the 0.10 g ·L-1 PC group (1.043 0 ± 0.062 2) had no significant differences (P ＞ 0.05).The differences between PC treated groups and control group were statistically significant (P ＜0.01),which showed HTMC treated with PC could increase the expression of mitochondrial complex Ⅰ mRNA.The differences in each PC treated groups were statistically significant (P ＜ 0.01),which showed the expression of mitochondrial complex Ⅰ mRNA were increased along with the concentration of PC gradually increased.Conclusion Exogenetic PC can increase the expression of mitochondrial complex Ⅰ mRNA in the oxidative damaged HTMC,and in a certain range of concentration,the protective effects of PC have the positive relationship of dose-effect,which suggest that PC may be a good candidate for further study of the clinical treatment of glaucoma.

Malignant tumor is an individual disease that caused by gene mutation and disorder of protein expression.The abnormity of mammalian target of rapamycin (mTOR) signaling pathways is closely related to the tumors,and its main biological function is the regulation of protein synthesis and vascular endothelial cell proliferation.However,the activation of mTOR can increase the expression of hypoxia-inducible factor-1 (HIF-1),maintain the acid microenvironment of tumor,promote tumor cell invasion and metastasis,and affect prognosis of tumor.At present,targeted therapy with mTOR and HIF-1 for new targets and gene therapy have become hot points.

Objective To observe the application of low dose CT scanning in lung puncture biopsy,and to discuss the feasibility and limitations.Methods 100 cases of CT guided percutaneous lung biopsy,used SPSS soft-ware to generate random numbers,odd number into the routine dose group,even number into low doses study group. The routine dose group of 50 patients underwent routine dose CT scanning(200mA,reconstruction thickness 2.0mm, pitch 16mm/rot)and puncture,and the low doses study group were given low dose CT scanning in 50 patients (10mA,reconstruction thickness 2.0mm,pitch 23mm/rot)and puncture.Two groups after routine disinfection punc-ture,were taken tissue samples for pathological examination.The two groups of CT scanning dose and image quality, the success rate of puncture and complications were compared.Results The success rate of puncture in conventional dose scan group was 90.00%;CT dose index weighted index CTDIw was (23.64 ±5.91)mGy;the average dose length product DLP was (172.31 ±43.08)mgy ×cm.The success rate of puncture of the low doses study group was 84.00%;CTDIw was (1.22 ±0.31)mgy;DLP was (8.56 ±2.14)mgy ×cm.The successful puncture rate of the two groups had no significant difference(χ2 =0.638 9,P=0.374 2);The radiation dose was statistically significant(CTDIw compare:t=2.798 3,P=0.005 4;DLP compare:t=2.684 9,P=0.007 8);The image quality can meet the need of puncture biopsy;At the same time,the two groups had no severe complications.Conclusion Low dose than routine dose CT scanning in lung biopsy success rate has no difference,but which can significantly reduce the radiation dose.

Long noncoding RNA (lncRNA) comprises a group of RNAs that are longer than 200 nucleotides. The lncRNA does not contain functional open reading frames and cannot encode proteins. RNA accounts for a large proportion in the total noncoding RNAs. The number, type, and function of lncRNA are unclear, so they have been called the dark matter of the genome. With the applica-tion of a new generation of gene sequencing technology, lncRNA is found to be involved in the mechanisms mediating the signal trans-duction pathway, regulating the cell cycle, and inducing cell apoptosis. In this article, the authors summarized the up-to-date research progress on lncRNA in digestive system neoplasms in China and overseas to provide new insights into the genetic diagnosis and treat-ment of digestive system neoplasms in clinics.

Caveolae is a specified micro-domain of plasma membrane, which consists of caveolin and many lipid molecules and membrane proteins. Caveolae plays important roles in internalization of extra-membrane molecules, transmembrane signal transdution and transport of cholesterin. Recent studies indicated that caveolae and its components were up-regulated in multidrug resistant tumor cells and might participate the development of multidrug resistance of tumor cells. This paper concentrated on the role of caveolae in tumor multidrug resistance.

Objective To investigate the incidence and risk factors of hallucination in patients with Parkinson’s disease (PD) by using a questionnaire. Methods Ninety-one patients with PD from outpatient and inpatient departments of Neurology and 38 healthy subjects were recruited. Mini-mental state examination (MMSE), unified Parkinson's disease rating scale-Ⅲ(UPDRS-Ⅲ), Hoehn-Yahr, interleukin 6 (IL-6) and C-reactive protein (CRP) were examined in all PD. According to the PPQ-B scores, the PD patients were divided into two groups:the hallucination group (PPQ-B≥1) and non-hallucination group (PPQ-B=0). Logistic regression model was used to explore the risk factors. Results Twen?ty-nine of 91 patients had hallucination and the incidence was 32%. Age and the levels of IL-6 and CRP were signifi?cantly higher in hallucination group than in non-hallucination group. Meanwhile, the duration of illness and MMSE were significantly higher in hallucination group than in non-hallucination group. Logistic regression revealed that the age and duration of illness were independent risk factors of hallucination and the Odds Ratios (OR) were 1.09 (95% CI:1.04~1.32, P<0.05) and 1.43 (95%CI:1.21~1.87, P<0.05), respectively. The risk of hallucination increased by 51%and 59%for each doubling of IL-6 and CRP levels in PD patients and the ORs were 1.51 (95%CI:1.13~2.11, P<0.05) and 1.59 (95%CI:1.07~2.66, P<0.05), respectively. Conclusions Controlling the levels of serum IL-6 and CRP plays an impor?tant role in delay or prevention of the hallucination of PD patients.
