Glaucoma is the first leading cause of irreversible blindness and the second leading cause of blindness worldwide. Numerous studies have shown that elevated intraocular pressure ( IOP ) is one of the major risk factors for the development and progression of glaucomatous optic nerve damage. However, there have been 50% of primary open-angle glaucoma ( POAG ) patients with typical glaucomatous optic neuropathy in whom the IOP measurements have always been in the normal range, and some patients develop typical glaucomatous optic neuropathy with the well controlled IOP. These phenomena cannot be explained by the theory of high intraocular pressure. The pathogenesis of glaucomatous optic nerve damage in these patients with normal IOP needs to be further discussed. Numerous studies at home and abroad have shown that: 1. the surrounding anatomy of the optic nerve including the IOP, the anatomy and biomechanics of the lamina cribrosa and retrobulbar orbital cerebrospinal fluid pressure may be of importance for the pathogenesis of the POAG;2. patients with normal tension glaucoma had significantly lower cerebrospinal fluid pressure and a higher trans - lamina cribrosa pressure difference compared with normal subjects; 3. patients with ocular hypertension had significantly higher cerebrospinal fluid pressure, however, there is no difference in trans -lamina cribrosa pressure compared with normal subjects. Based on the above research, now we make a review about the research advance of the relation between intracranial pressure and glaucoma optic nerve damage and the available measurements about noninvasive intracranial pressure in clinical in this paper.

Objective To discussion the efficacy and safety of single channel and double chinese -made biliary stent in high biliary malignant hilar obstructive jaundice .Methods We reviewed the clinical data of 24 malignant hilar obstructive jaundice patients treated with single channel and double chinese -made biliary stent from October 2012 to December 2013 retrospectively.Of which 9 cases(study group)were used for single channel and double stenttreatment,and 15 cases(control group)were treated by the bilateral channel;We compared the number of intraoperative percutaneous puncture hepatic duct , radiation exposure doses , operation time , drainage effectiveness and complication rates in the two groups .Results The average number of percutaneous puncture hepatic duct in the study group was 1.44 ±0.53 times,which was significantly lower than the control group (3.73 ±0.70 times).The fluoroscopy time and radiation exposure dose of study group was 1152.22 ±335.61 s and 653.22 ±207.02 mGy,which was slightly less than the control group (1236.93 ±463.43 s and 727.00 ±348.52 mGy),the difference was not statistically significant (P=0.638;P=0.572).Liver function was tested after 4 W, the drainage effectiveness of study group and the control group were 88.9%(eight-nineths),86.7%(thirteen-fifteenths),the difference was not statistically significant .One case occurred bile leakage in the study group ,2 pa-tients with hemobilia in control group ,both groups showed no serious complication .Conclusion The single chan-nel and double chinese -made biliary stent to treat high biliary malignant hilar obstructive jaundice is minimally injured and effective ,which can be selectively applied to treat patients with hepatic hilum malignant obstructive jaundice .

2(38.2 vs 34.4 months, P=0.214).The 1, 2 and 3-year local control rates were 84.0%, 72.9% and 56.7%, respectively.Conclusion:When given a sufficient combination of modality treatment for selected elderly patients with esophageal carcinoma, the tolerance and therapeutic efficacy were not significantly worse than those of younger patients.Therefore, combined chemoradiotherapy for elderly patients is worthy of further study.

Objective To investigate the role of Keratin 13 gene in laryngeal carcinogenesis. Methods To detect the deletion frequency of keratin 13 sequence indirectly by LOH analysis at DNA level using 5 STR primers within and near keratin 13 gene in 100 cases. Results LOH was found in all of the microsatellite loci, and the LOH frequencies were 30.48%, 26.02%, 21.62%, 37.66% and 21.51% at D17S1964E, D17S2092, D17S791, D17S1665, and D17S808 positions respectively. The frequencies of LOH were not related to the type of laryngeal carcinoma. Conclusion Keratin 13 gene might play an important role in the laryngeal carcinogenesis,and further research is necessary to confirm it.

Objective: To observe the efficacy of acupoint sticking with Jianpi Tongjing Zhitong ointment in the treatment of functional dyspepsia due to liver-qi stagnation and spleen deficiency and its effect on serum 5-hydroxytryptamine (5-HT) and ghrelin contents. Methods: One hundred patients with functional dyspepsia due to liver-qi stagnation and spleen deficiency were divided into a treatment group and a control group by the random number table method, with 50 cases in each group. The treatment group received acupoint sticking with Jianpi Tongjing Zhitong ointment and the control group was treated with mosapride citrate orally. Patients were treated for 4 weeks as a course. The therapeutic efficacy was compared after one-course treatment and the differences in gastric emptying rate, and serum 5-HT and ghrelin contents between groups were compared before and after treatment. Results: The total effective rate was 79.6% in the control group and 89.4% in the treatment group, showing significantly different between groups (P<0.05). After treatment, the gastric emptying rate and serum ghrelin content of the two groups increased significantly, and the serum 5-HT content decreased significantly, the intra-group differences were significant (all P<0.01). After treatment, the gastric emptying rate and serum ghrelin content were significantly higher in the treatment group than those in the control group, while the serum 5-HT was significant lower in the treatment group, the inter-group differences were significant (all P<0.05). A negative correlation (r=-0.59) was observed between serum 5-HT content and gastric emptying rate, and a positive correlation (r=0.64) was observed between serum ghrelin content and gastric emptying rate, showing statistical significance (all P<0.01). Conclusion: Acupoint sticking with Jianpi Tongjing Zhitong ointment has a remarkable clinical efficacy in treating patients with functional dyspepsia due to liver-qi stagnation and spleen deficiency and is able to influence the secretion of serum 5-HT and ghrelin. Improving the gastrointestinal motility through the regulation of related brain-gut peptides is suggested as an underlying mechanism for this therapy.

Objective an experimental animal model of acute myoc ardial infarction (ANI) was established by opening chest and ligation of the left anterior descending (LAD) coronary artery. Methods a total of 20 rabbits were opened chest and ligated LAD under sterilization. Electrocardiogram (ECG) and myocardial-enzymes in blood serum were investigated. Results ECG of all rabbi t s showed normal before operation. Irmediately after and 1/2 hour after ligation , ST-segment elevated and ECG showed ambulatory changes for 7 and 9 rabbits respectively. Two hours after LAD ligation, the change of ECG for 2 rabbits wa s not typical and 2 of them died during experiment. Four weeks after operation, E CG of 18 rabbits showed the chest leads had pathologic Q waves. Twenty-four ho urs after LAD ligation, AST, LDH, LDH-1, CK and CK-MB in blood serum were significantly increased. There was significant difference compared with before operation (except LDH) (P<0. 0l). Conclusions:The method was sim ple and well repeated. The formation of myocardial infarction was reliable and rabbits were maintained for a long time after operation. It provides a valuable animal mode l for the experiment study of coronary heart disease.

Actin cytoskeleton in podocyte is a complicated network structure,and the stability of this structure depend on many proteins which located in slit diaphragm,the apical membrane domain and the basal membrane domain with the stimulus of mechanical stress,the actin cytoskeleton can be adaptive regulated to maintain the normal function of glomerulus,and several signal pathways involve in the process,such as RhoA/Rho kinase signal pathway and TRPC6.
