OBJECTIVE:To investigate therapeutic efficacy and safety of Naoxintong capsules combined with edaravone in the treatment of acute cerebral infarction. METHODS:80 patients with acute cerebral infarction were analyzed retrospectively and divid-ed into observation group (40 cases) and control group (40 cases) according to drug use. Both groups was given Aspirin enter-ic-coated tablets 10 mg orally,once a day,to control platelet aggregation,20% Mannitol injection 250 mL intravenously,every 12 hours,to control brain edema,Potassium chloride sustained-release tablets 0.5 g orally,3 times a day,to maintain water and elec-trolyte balance and other conventional treatment. Control group was additionally given Edaravone injection 30 mg added into 0.9%Sodium chloride injection 100 mL intravenously within 30 min,once a day;observation group was additionally given Naoxintong capsules 1.6 g,3 times a day on the basis of control group. Treatment course of both groups lasted for 10 d. Clinical efficacies of 2 groups were observed as well as the ET-1 and NO content,IL-8,hs-CRP,FT3,FT4 and TSH level,NIHSS and ADL score,the occurrence of ADR before and after treatment. RESULTS:Total response rate of observation group was significantly higher than that of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in the ET-1 and NO content,IL-8,hs-CRP,FT3,FT4 and TSH level,NIHSS and ADL score between 2 groups(P>0.05). After treatment,the ET-1 content,IL-8 and hs-CRP level,NIHSS score in 2 groups were significantly lower than before,and the observation group was lower than the control group;the NO content,TSH,ADL score in 2 groups were significantly higher than before,and the ob-servation groups was higher than the control group,with statistical significance(P<0.05). There was no statistical significance in the levels of FT3 and FT4 between 2 groups before and after treatment(P>0.05). No severe ADR was found in 2 groups. CON-CLUSIONS:Based on routine treatment,Naoxintong capsules combined with edaravone in the treatment of acute cerebral infarc-tion can improve therapeutic efficacy and vascular endothelial function,relieve inflammatory reaction and recue TSH levels,more-over,don't increase the occurrence of ADR.

Objective To elucidate the relationship between LYVE-1 and VEGF-C and their expression in laryngeal squamous cell carcinoma(LSCC),and provide theoretic evidence for the judgement of metastasis and prognosis of LSCC,also for the treatment.Methods An immunohistocbemical analysis was performed to 50 specimens of LSCC with lymphatic endothelial marker LYVE-1.Quantitation of lymphangiogenesis growth factor VEGF-C by RT- PCR was performed to 30 specimens of LSCC.Finally the correlation between LVD and VEGF-C mRNA was analyzed with statistics methods.Results LYVE-1 (+) was observed in all LSCC.The median copy number of VEGF-c mRNA was 4-5-fold higher in LSCC than in adjacent normal tissue.There was correlation between tumor VEGF-C mRNA copy number and intratumoral LVD.Conclusion Lymphatic vessels existed in LSCC.There was correlation between high levels of LVD in LSCC than in normal tissue.The high level of VEGF-C may accelerate the lymphatic metastasis by promoting the proliferation of lymphatic vessel.

Objective To investigate the current situation and the development of autism rehabilitation service institutions in China. Methods The finance, supervision and management, recipients and rehabilitation standards of 117 autism rehabilitation service institutions were investigated with questionnaire and interview.

AIM:To investigate the ability of a metal complex ammonium tetrathiomolybdate (ATTM) to re-lease H2 S and its cytoprotective effect on an oxidative injury model .METHODS:Released H2 S was absorbed in a reaction flask from ATTM dissolved in the cell medium .Staining with dichlorodihydrofluorescein diacetate or rhodamine 123 fol-lowed by photofluorography was conducted for the observation of reactive oxygen species ( ROS) and mitochondrial mem-brane potential (ΔΨm) levels, respectively.Cell viability and release of lactate dehydrogenase (LDH) from the cells were measured with commercial kits.RESULTS:Similar to another H2S donor GYY4137, ATTM had an ability to release H2S in the cell medium in a dose-dependent manner .Treatment of human skin HaCaT cells with ATTM at concentrations of 25~400 μmol/L didn’ t significantly alter cell viability .Exposure of the cells to ultraviolet rays or a ROS donor H 2 O2 in-creased the intracellular ROS levels .Treatment with 400 μmol/L H2 O2 significantly reduced the viability of HaCaT cells (P<0.01).However, before the treatment with H2O2, pretreatment with ATTM at 100 and 200 μmol/L markedly pre-vented the H2O2-induced cell injury (P<0.01).In addition, the treatment with H2O2 triggeredΔΨm loss (P<0.01) and LDH release from the cells (P<0.01).Prior to suffering from H2O2 injury, the preconditioning with 200 μmol/L ATTM significantly improved ΔΨm levels ( P<0.05 ) and attenuated LDH release from the cells ( P<0.01 ) .CONCLUSION:ATTM is capable of releasing H 2 S and protecting human skin cells against oxidative injury .

Objective To detect the expression of Cancer-Testis antigen NY-ESO-1 in human laryngeal squamous carcinoma (LSC) and to explore its significance in immunotherapeutic application. Methods The expressions of NY-ESO-1 protein in the LSC and in the pathologically positive lymph nodes were detected by PV-9000 Immunohistochemistry. Western blotting was also employed to measure the expressions of NY-ESO-1 in the tumor core region(TC), the tissues at the sites of 0.5cm, 1.0cm away from LSC periphery and the distant normal larynx tissues. Results NY-ESO-1 protein expression was positive in 30 out of 69 (43.48 %) cases of LSC. The expression level of NY-ESO-1 protein were found to significantly decrease by tums in TC and corresponding adjacent tissues (P ＜0.01). None of the nine normal larynx tissues expressed NY-ESO-1 protein.It did not display an obvious correlation between the expression of NY-ESO-1 with T staging, pathological grading and lymph node metastasis (P ＞0.05). Its positive expression was found in pathologically positive cervical lymph nodes, which were significantly lower than that in the primary site (P ＜0.05). Conclusion NY-ESO-1 protein express at high level in human laryngeal squamous carcinoma, and they may play a role in genesis and development of tumors, which suggests that NY-ESO-1 gene might be used as target antigens for immunotherapy of LSC and the further research is necessary.

Summary Vertical nystagmus is a vertical nystagmus caused by structural abnormalities and/or dysfunction of the central vestibular system and observed in situ in the center of the eyeball. There are two kinds of nystagmus （UBN） and downbeat nystagmus （DBN） according to the direction of nystagmus. The diagnosis of UBN is mainly made by naked eye or electronystagmography/viewer. It is a common neuro-ophthalmologic sign in the field of vestibular medicine. In this paper, the mechanism of vertical nystagmus formation and the location of lesions were briefly introduced, in order to provide help for the diagnosis and treatment of Vertigo.
