Stroke is the most common cause of aphasia. Traditional speech-language therapy remains the mainstay treatment of aphasia, however, its efficacy is uncertain. Although a number of studies have been carried out to investigate the role of pharmacological agents in the treatment of aphasia, the conclusions are controversial, This article reviews the state of pharma-colotherapy for poststroke aphasia.

Aim To isolate HIV-1 from the blood specimen of HIV-infected persons, and study on the features of the isolates. Methods PBMCs from 10 heparinized blood specimens of HIV-1 infected persons were collected to isolate the virus with PBMC cocultivation method. Neuramindase was added to the culture medium to raise the HIV isolation rate. The supernatant of cocultures were detected by p24 antigen capture assay and also IFA test was used to identify the isolates. Cell tropism of the HIV-1 isolates was tested byuse of H9 and MT4 cell lines, respectively. Results HIV-1 was isolated from9 of the 10 specimens, the isolation rate could reached 90%. The 9 isolates were used to infect MT4 cells, respectively, and all of them could cause cell syncytias.8 of the isolates showed only a transient infection in MT4 cells, but the isolate FJ113 could infect MT4 successively, OD values kept no changes even it passed 15 generations, therefore, it is consider as a rapid/high replicating virus. Conclusions Addition of neuramindase into T cell culture medium may useful to raise HIV isolation rate. Most of HIV-1 isolates in Fujian are M tropic.

Objective To observe the effect of traditional Chinese medicine internal and external treatment on chronic osteomyelitis.Method Chronic osteomyelitis experimental animal models were set up with debridement, then it was random divided into two groups ( antibiotics group for the control group, antibiotics and traditional Chinese medicine group for the observation group).After treatment for 10 days, new capillaries in the tissues surrounding sinus crossings were detected by pathological observation and VEGF expression was determined by ELISA.Result VEGF expression and vascular points of tissues surrounding sinus crossings of antibiotics with traditional Chinese medicine group were obviously higher than that of antibiotics group[ (47.48 ±3.22) μg/ml vs (28.26 ±2.61)μg/ml, P ＜0.01;8.03 ±1.73 vs5.17 ±2.89, P＜0.05 ].Conclusion Traditional Chinese medicine internal and external treatment can improve VEGF expression and increase capillary number inside tissues surrounding sinus.crossings , thus it can promote the healing of chronic osteomyelitis.

Objective To study the morphological appearance and pathological basis of the fine pulmonary reticulation at HRCT.Methods One hundred and seven patients were analyzed about the morphology findings and dynamic changes on pulmonary HRCT.Twenty-four coal worker's pneumoconiosis(CWP)specimens were examined to make comparison between CT and pathology.The data was analyzed by using the Chi-square test.Results The reticular gap was less than 3 mm in diameter.The morphology of reticulation was round or irregular.Pulmonary parenchyma was seen between the gaps.The reticular wall was smooth or coarse.The thickness was less than 1 mm.One hundred and seven patients had accompanying signs including ground-glass opacity(68.2%,73 patients),crazy paving(23.4%,25 patients),interlobular septal thickening(84.1%,90 patients),emphysema(32.7%,35 patients),interface sign(58.9%,63 patients),traction bronchiolectasis(41.1%,44 patients)and honeycombing(26.2%,28 patients).The differences of the honeycomb,traction bronchiolectosis,interbobular septal thickening,interface sign and paving were statistically significant between the fibrotic group and pneunonia(P＜0.01).Pneumonia showed extensive area of ground-glass opacity(GGO)with fine reticulation.Fine reticulation with both interlobular septal thickening and small nodules were observed more frequently in lmphangitic carcinomatosis.Idiopathic pulmonary fibrosis(IPF)showed fine reticulation among the honeycombing.Connective tissue disease (CTD)showed fine reticulation with rarely honeycombing and it could be partly absorbed.Fine reticulation with emphysema was seen in chronic bronchitis.In the 58 follow-up patients,the fine reticulation increased in 26 patients,decreased or disappeared in 22 patients and showed no change in 10 patients.The major pathological basis of the fine reticulation was intralobular interstitial thickening,including fibrosis hyperplasia,inflammatory cells and tumor cells infiltration,effusion filling,smut deposition and so on.Conclusions The fine reticulation was caused by intralobular interstitial thickening including inflammation,interstitial hyperplasia,pulmonary fibrosis and tumor.The fine reticulation is helpful to prompt the diagnosis of these diseases,but the diagnosis need its combination with the other CT findings and dynamic changes.

Objective To explore the expression of acid seining ion channels-3 (ASIC3) in lung tissue in rats with acute lung injury (ALI). Method Twenty four male Sprague-Dawley (SD) rats were randomly divided into four groups: LPS groups (LPS 2 h, LPS 4 h, LPS 6 h group, n=6), stimulated by LPS for 2, 4, 6 hours, respectively; normal control group, injected with saline (NS group, n=6). The ALI models were produced through venous injection of LPS, and the criteria was the characteristic pathological changes in the lung tissue. Ar-terial blood gas analysis was observed, lung wet and dry weight ratio (W/D), lung histopathology and ASIC3 ex-pression were detected. Data were expressed as mean±standard deviation. Independent Sample T test and One-way ANOVA and Kendall's tau_b were used for comparison in SPSS 13.0, and changes were considered as statistieal-ly significant if P value was less than 0.05. Results The partial pressure of oxygen (PaO2) in LPS 2 h, LPS 4 h, LPS 6 h group was (67.47±6.01), (59.17±7.18), (52.54±7.62) , respecively, and was significantly lower than that in eontrol group (98.15±1.06) (P<0.01). Compare with control group, pH was significantly lower in LPS4 h group (7.28±0.04), LPS6 h group (7.24±0.03) (P<0.01). Inflammation cells gradually increased, alveolar septum was widened, edema existed in interstitial spaces, and pulmonary structures gradually destroyed in LPS groups.The expression of ASIC3 in LPS4 h, LPS 6 h group was (205.91±10.12), (196.51± 18.60), respectively, and was significantly lower thanthat in control group (220.23±10.11) (P<0.05). The W/D in LPS 6 h group was (5.18±0.21), and was significantly higher than that in the control group (4.45± 0.18) (P<0.05). Conclusions ASIC3 is expressed in alveolar epithelial cells and bronchial epithehal cells in LPS-induced ALI rats.

Objective To investigate the anesthetic management of perventricular closure of ventricular septal defects (VSD) under transesophageal echocardiography. Methods A retrospective review of the clinical data of 52 children who underwent perventricular closure of VSD under transesophageal echocardiography were analyzed. All the children were performed tracheal intubation under general anesthesia, and the electrocardiogram, pulse blood oxygen saturation, invasive arterial pressure, central venous pressure, end tidal carbon dioxide partial pressure, temperature and urine output were continuously monitored throughout the procedure. The transesophageal echocardiography was necessary for guiding transcatheter or per-ventricular device placement. Results Perventricular closure of VSD was successfully completed in 51 children under transesophageal echocardiography, the operation time was (76.7 ± 36.4) min, the anesthesia time was (89.5 ± 27.1) min; 1 child was converted to open surgical repair. Conclusions The intraoperative transesophageal echocardiography technology is the key to the success of the surgery. At the same time of analgesia and sedation, the anesthesia doctor needs to pay attention to the changes of hemodynamics in children.

HLA-G belongs to non-classical HLA-class Ⅰ genes.It is expressed in the fetal-maternal interface on the extravillous cytotrophoblast and in such immune privilege tissues as the cornea and pancreas.However, under pathological conditions, such as tumor, inflammatory diseases and post transplantation, HLA-G is expressed abnormally.HLA-G can interact with its acceptors or immune cells and suppress the function of immune cells, which facilitates the escape of the surveillance of the human immune system and the consequent damage.In clinical studies,HLA-G is related to some clinical parameters.This review will focus on the expression, function and regulatory mechanisms of HLA-G in cancer immunology.

Objective To respectively analyze the patterns and possible predictors of recurrent strokes among patients with initial ischemic stroke.Methods Three hundred and sixty-one patients with recurrent strokes (acute ischemic stroke or intracerebral hemorrhage) after initial ischemic strokes were collected from Jan 2004 to Dec 2009.The data about conventional risk factors such as smoking,heavy alcohol drinking,hypertension,diabetes,hyperlipidemia,heart diseases,head trauma,migraine,family history of cardiovascular disease,and the use of preventive medications were collected and analyzed among patients with different types of recurrent strokes.Results Patients (n =361) were divided into ischemic stroke group (n =321) and hemorrhagic stroke group (n =40) according to the recurrent stroke type.The ischemic stroke group was further divided into the anterior circulation stroke subgroup (n =234),the posterior circulation stroke subgroup (n =75) and watershed cerebral infarction or multiple infarction subgroup (n =12).Multivariate logistic regression analysis revealed that older age at initial stroke onset (OR =1.036,95 ％ CI 1.006-1.067,P =0.02) and hyperlipidemia (OR =2.253,95 ％ CI 1.092-4.647,P =0.028) were both the independent risk factors for the recurrent ischemic stroke.Comparing the subgroups,multivariate logistic regression analysis showed that atrial fibrillation (OR =4.217,95％ CI 1.489-11.942,P =0.007) was the independent risk factor for the recurrent ischemic stroke in the posterior circulation territory.Conclusion Aging and hyperlipidemia are possible predictors of recurrent ischemic stroke after the initial ischemic stroke which would be useful for individualized secondary prevention of stroke.

Objective To compare distribution difference in risk factors of patients with first-ever ischemic stroke (IS) of different age and gender.Methods A total of 1027 patients admitted to the neurological department in Shanghai Renji Hospital with first-ever IS were recruited and divided into young adult group ( ＜ 50 years old),middle-aged group (50-80 years old),and very old group ( ＞ 80 years old)according to their ages.Risk factor analysis included history of smoking,high alcohol consumption,hypertension (HT),diabetes mellitus (DM),heart diseases,atrial fibrillation (AF) and family history of cardiovascular diseases.Results Female patients were globally older than male patients (71.1 vs 65.7,P ＜ 0.001 ) at the first attack of IS and having higher prevalence of DM (26.8％ vs 19.2％,P =0.004 ),heart diseases (28.8％ vs 19.2％,P＜0.001) and AF (7.6％ vs 3.9％,P=0.009).However,female patients were less likely to drink heavily ( 1.0％ vs 31.6％,P ＜0.001 ) or smoke (4.4％ vs 59.9％,P ＜0.001 ) than the male patients.The rates of smoking and heavy drinking in young adult group were higher than that in other two groups.Patients in very old group had higher prevalence of heart diseases and AF but lower proportion of positive family cardiovascular diseases history than patients in other two groups.HT and DM were equally frequent among three groups.In young adult group,female patients were more likely to have heart diseases and family history of heart diseases (P =0.015 and P =0.048).In middle-old group,HT,DM,heart disease and AF were more common in women than in men (P =0.021,P =0.004,P =0.001 and P =0.039).Conclusion There are differences in risk factor distribution in patients with first-ever IS of different age and gender.Therefore,screening and health education should be performed in allusion to different risk factors.
