Objective: To analyze auditory verbal memory impairment after isolated stroke lesions in subcerebral structure. Methods: Auditory verbal memory function was examined in 25 normal elderly and 83 patients at 20th day after their admission to hospital for acute cerebrovascular disease with non-aphasiaand solitary lesions as identified by cranial CT or MRI. Results: Test findings suggested patients with stroke of internal capsule-basal ganglia, cerebellum and pons lesion have processing impairments of recent memory and subjective organization which are related to concentration and arousal levels. Conclusion: Stroke of subcortical regions such as lesions of thalamus,internal capsule-basal ganglia,cerebellum and pons may induce memory impairments with unique impaired cognitive coding modalities.

Objective To study the effect of labeling esophageal carcinoma with sliver clips on two sides by esophagoscopy in mapping the target for conformal radiotherapy (CRT). Methods Eighty patients with esophageal carcinoma (28 patients in early stage, 52 patients in late stage), who were eligible for CRT, were collected and the tumor volume was detected by three methods: CT (A),CT combined with X-ray (B) and CT combined with sliver clip labeling by esophagoscopy (C). The differences of the tumor length and position in head-foot site (Y-axsis) among three methods were compared. Results The comparison of average length of tumor in early stage patients showed significant difference among three methods in all types of tumor (F= 4.07 ~ 7.43, P<0.05 ) except papillary type (F= 1. 71, P>0. 05). There was difference (ranged from 0. 5 cm to 2. 0 cm) in detection of position in head-foot site between A and B methods and C method. Significant difference was found in determining the displacement on head-foot site among three methods (F = 34. 36 ~193.50,P <0.01). The comparison of average length of tumor in middle or terminal stage patients showed significant difference among three methods in all types of tumor (F=4. 07~30.10 ,P<0.05) except mushroom type (F = 2.44, P> 0. 05). Significant difference was found in determining the displacement on head-foot site among three methods (F= 12.00 ~ 21.16, P < 0. 01 ). Conclusion These findings indicate that C method is more sensitive and correct in mapping the target for CRT in comparison with other two methods.

Objective To investigate the changes of plasma microRNA-223(miR-223) and HMGB-1 in pediatric sepsis patients.Methods There were 49 children with sepsis enrolled in the study (sepsis group),severe sepsis group (n=25) and general group (n=24). Meanwhile, 50 healthy children (normal control group) were selected as control group. The expression levels of plasma miR-223and HMGB-1 (high mobility group box 1) were detected. The predictive values of miR-223and HMGB-1 in plasma of children with sepsis were evaluated by receiver operatingcharacteristic (ROC) curve.Results The plasma miR-223 and HMGB-1 expression levels in severe sepsis group and general group were up-regulated compared with those in the normal control group (F=63.02, 76.32,P<0.05). The area under ROC curve of miR-223,HMGB-1 predicting sepsis were 0.904 (95%CI 0.821-0.998), 0.748 (95%CI: 0.625-0.903). There was positive correlation between miR-223 and HMGB-1 (r=3.532, P<0.05). Conclusions The expression levels of plasma miR-223 in children with sepsis are signiifcantly up-regulated, which can be used as early diagnostic markers to relfect the severity of inlfammation in some degree.

[ABSTRACT]AIM:Toinvestigatetheeffectofsilencingisocitratedehydrogenase2(IDH-2)genebysmallinter-fering RNA (siRNA) on the biological characteristics of human small cell lung cancer cell line NCI -H446.METHODS:IDH-2 expression was knocked down in human small cell lung cancer cell line NCI -H446 by siRNA-IDH-2.The expression level of IDH-2 was determined by real-time PCR and Western blotting .The cell proliferation was measured by CCK-8 as-say , the protein expression of MAPK p 42 was detected by Western blotting , and the cell cycle was analyzed by flow cytome-try.The migration was observed using Transwell cell migration system .BALB/c nude mice were subcutaneously injected on the back with NCI-H446 cells transfected with siRNA-IDH-2/negative control siRNA or non-transfected cells to study the tumor growth .RESULTS:siRNA-IDH-2 remarkably down-regulated the expression of IDH-2 and MAPK p42 in the NCI-H446 cells.siRNA-IDH-2 inhibited both the proliferation and migration abilities of NCI-H446 cells, and the cell cycle was arrested in S phase as compared with negative control group .Additionally, the volume of xenograft tumors in siRNA-IDH-2 group was significantly decreased as compared with control group .CONCLUSION:siRNA-IDH-2 down-regulates the expres-sion of IDH-2 in NCI-H446 cells, reduces the cell migration efficiency and inhibits the tumor growth in vitro and in vivo.

BACKGROUND:Human embryonic stem cels are able to self-renew indefinitely and have the capacity to differentiate into al three germ layers (ectoderm, endoderm and mesoderm). These properties imply great potential in the basic research and clinical application, including regenerative medicine, drug screening and toxins, early human embryo, cel transplantation, gene therapy,etc. However, it is a substantial chalenge to develop efficient techniques for their large-scale culture under defined conditions, and for controling and directing their differentiation. For therapeutic purposes, many scholars are trying to establish methods for maintaining pluripotency in defined xeno-free conditions and scalable culture systems. OBJECTIVE:To discuss the progress of serum-free culture systems in human embryonic stem cel research reported in recent years and to highlight the chalenges and advances being made towards the development of serum-free and xeno-free culture systems suitable for therapeutic applications. METHODS:A computer-based search of CNKI and PubMed academic database was performed for articles addressing serum-free culture systems of human embryonic stem cels published from 2008 to 2015. Repetitive and old articles were excluded. Finaly, 58 articles were summarized. RESULTS AND CONCLUSION:Several groups have attempted to exclude individual animal components by using feeder-free matrices, feeder cels of human origin, or defined xeno-free media, aiming to select a suitable matrix and medium that can minimize or not use heterologous components, in order to obtain cel lines at clinical level. However, the current cel products are far from clinical application. There are stil many problems to be solved, such as standardization, normalization and individualization of cel products. With the normative development of stem cel research and industry, human embryonic stem cel products are expected to be widely used in clinic.

Kyrgyzstan is a mountainous country in the northeastern part of Central Asia which shares borders to the southeast with China. Due to their extreme environment and climate, there are a diverse range of species of plants. Many of the plants used in Kyrgyz folk medicine have not been studied using modern scientific techniques. This paper introduced the basic situation of medicinal herbs in Kyrgyzstan by comparing the differences traditional use between China and Kyrgyzstan, and looked for traditional medicinal plant research to provide basis for the development and cooperation of China and Kyrgyzstan.

Objective To investigate the effect of physical training on plasma N-terminal pro-brain natri- uretic peptide(NT-proBNP)levels in patients with chronic heart failure(CHF).Methods Eighty NYHAⅡ-ⅢCHF patients were randomly divided into a training group(n=42)and a control group(n=38).A 6-minute walk- ing test was performed within 24 hours after the patients were admitted.The 6-minute walking distance and plasma NT-proBNP levels were determined before and after 8 weeks of programmed physical training.The patients of both groups were treated with routine drugs for heart failure.6-minute walk training was only performed in the training group twice a day for 8 weeks.Results Physical training could significantly reduce plasma NT-proBNP levels and improve performance on the 6-minute walking test.Conclusions Physical training could significantly reduce plas- ma NT-proBNP levels and improve the motor function of patients with CHF,and could be helpful in delaying the de- velopment of CHF.
