Objective To evaluate the nutrition status and the prognosis of acute stroke patients with hy-pothyroidism during hospitalization. Methods The clinical data of 28 acute stroke patients with hypothyroidism (study group) and 28 stroke patients with normal thyroid function (control group) were retrospectively analyzed.Results After (10±4) days of hospitalization, hemoglobin and serum albumin levels in study group significantlydecreased ( P < 0. 05 ).

They were significantly lower than that in IR group, but more than that in normal group(P＜0. 05). The expression of GRP78 at corresponding times in the treatment group were 0. 158±0.012 (repeffusion 3 h), 0. 175±0. 005 (reperfusion 6 h), 0. 125±0. 013 (reperfusion 12 h), 0. 079±0. 004 (reperfusion 24 h), respectively. They were significantly higher than that in IR group and normal group (P＜0. 05 ).

They were significantly lower than that in IR group, but higher than that in normal group(P＜0. 05). Conclusions Fetal rat cerebral neuron apoptosis following intrauterine distress is associated with the action of endoplasmic reticulum and mitochondrium. Up-regulation of GRP78 induced by 2DG counteracts primary cellular damage caused by endoplasmic reticulum stress. 2DG plays a protective role for fetal rat cerebral neuron following intrauterine distress.

Objective To verify the application of anterior segment perfusion culture and trabecular meshwork (TM) organ culture for glaucoma study. Methods TM tissue was cultured by perfused anterior segment and TM organ culture, light microscopy was used to observe the TM cells and intercellular spaces.Results IOP of the porcine anterior segments perfused under constant flow at 0.1 mL/h could bekept in normal range(10～12 mmHg). The IOP was elevated with the increasing of perfusion rate, while the morphology and structure of the tissue were well preserved. TM cultured by TM organ culture could also reserve the tissues well, but the intercelluar spaces collapsed. Conclusion Anterior segment perfusion model could be a short-term high-pressure model and may simulate the normal physical state. Adequate perfusion was necessary for normal TM.

Objective To investigate the characteristic and diagnosis of left ventricular diverticulum. Meth-ods As one left ventricular diverticulum patient was diagnosed by echocardiography in our hospital,we reviewed and analyzed about published in China. Results Left ventricular diverticulum is a rare disease of congenital heart malfor-marion, Echocardiographic characteristics of the left ventricular diverticulum is the saccular evngination of the left ven-tricular wall with the neck of the diverticula being smaller than the body. Left ventricular diverticulum is classified into contractile muscular type and fibrous type ,The saccular wall of contractile muscular diverticulum remain a normal mo-tion and is thinner than the normal wall The saccular wall of the fibrous diverticulum is due to a loss of myocardial thickness, as thin as aneurysm with a dyskinetic motion. Conclusion Left ventricular diverticulum is a rare disease in clinic, echocardiography is very important for diagnosing classifying.

Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.

Danshen is one of the traditional Chinese herbal medicines and nas a long history or being used clinically in the treatment of cardiovascular and cerebrovascular conditions such as coronary heart disease and angina pectoris. Tanshinone IIA is a derivative of phenanthrene-quinone isolated from Danshen. It has been reported to be the major bioactive compound of Danshen and has diverse biological effects. Recent studies demonstrated that tanshinone IIA had neuroprotective effects on experimental ischemic stroke through its antiinflammatory, anti-oxidant, anti-apoptosis effects and its inhibitory effect on excitatory amino acid toxicity. In this review, we summarized all the recent progresses on the protective effect of tanshinone IIA on cerebral ischemic stroke. Hopefully, this article will throw some light on further study and application of tanshinone IIA.
