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 ). The requirement of calories and protein, incidence of pulmonary infections, alimentarytract hemorrhage and diarrhea, and hospital stays were significantly higher in study group than in control group (P < 0. 05 ). Conclusion The nutrition status is poor in acute stroke patients with hypothyroidism, who were more easier to be suffered from clinical complications and worse prognosis.

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.

Background Trans-corneally subretinal injection in rodent model is a useful method for genetic therapy,stem cell transplantation and the study on the ophthalmic research.Standarized operation process is critical for the successful treatment.However,there is no literature to report the detailed procedure and the influence of this technique on morphology and function of retina.Objective This sudy was to introduce a method of trans-corneally subretinal injection and evaluate its influence on the morphology and function of retina.Methods Trans-corneallly subretinal injection was performed on the left eyes of 2-month-old SPF C57BL/6J mice after dilation of pupils.A 301/2G disposable needle was used to puncture the cornea within the pupil area near limbus and avoid touching the lens and irises under eye surgery microscope.Then,a 33G blunt needle was used to insert into the vitreous and toward subretinal space via corneal puncture.Normal saline with 0.1％ fluorescein sodium of 1 μl was slowly injected into the space,and 2.5％ hydroxypropyl methylcellulose was dropped on ocular surface for the observation of the fundus clearly.According to the percentage of the retina filled with subretinally injected solution,the experimental eyes were divided into 80％-100％ area group,50％-70％ area group after injection,and the mice in the pseudo-injected group,in which injection procedure stopped just before the solution was pushed in to the subretinal space did not inject any solution after punctured.The right uninjected eyes of the mice served as normal control group.Four eyes were selected for each group.The structural changes were evaluated by optical coherance tomograpby (OCT) 1 day,2 days,3 days and 5 weeks after injection,and retinal function was assessed by the recored of electroretinography (ERG) 5 weeks after injection.The retinal sepcimens were prepared to examin the morphological changes by hematoxylin and esosin staning.The use of care followd the Regulations for the Administration of Affair Concerning Experimental Animals of Zhejiang Province.Results About 70％ of the injected eyes showed that retinal blebs filled with injected green fluorescein solution occupied 50％ or more retinal area with minimal damages.The focal detachment between neurosensory retinal layer and retinal pigment epithelium (RPE) was exhibited 1 day postinjection,and almost all the retinas retached 2 days after injection.In the fifth week after injection,the amplitudes of ERG b wave were (386.25±37.88),(357.50±41.03),(324.25±53.45) and (410.50±14.88) μV in the sham operation group,50％-70％ area group,80％-100％ area group and normal control group,respectively,showing a significant difference among the 4 groups (F=3.574,P=0.047),and the amplitudes of b wave in the normal control group were higher than those in the 80％-100％ area group (all at P ＜ 0.05).The detachment between retinal neuroepithelium layer and RPE layer,cell proliferation and transposition in the outer nuclear layer were dispalyed under the light microscope in the sham operation group,50％-70％ area group and 80％-100％ area group,and the disordered outer segment of photoreceptors at the injecting area was seen in the 50％-70％ area and 80％-100％ area groups at five weeks after injection.However,retinal sructure and morphology were normal at the non-injection area.Conclusions Trans-corneally subretinal injection is an effective and safe way for subretinal injection.

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.

Objective To investigate the effects of oestrogen-receptor(ER), progesterone-receptor(PR), vascular endothelial growth factor(VEGF) and kinase insert domaincontaining receptor(KDR) in uterine bleeding induced by intrauterine device(IUD). Methods Immunohistochemical method was used to detect the expressions of ER, PR, VEGF and KDR in endometrium from IUD bleeding group and normal control group, respectively. Microvessel density(MVD) was evaluated by using anti factor Ⅷ-related antigen (F8-RA) antibody to mark stromal microvessels. Results The expressions of ER, VEGF and KDR were significantly higher in IUD-induced endometrium bleeding group than those in control group(P0.05). MVD was significantly higher in IUD-induced endometrium bleeding than that in normal endometrium(P

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.

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.
