Objective To analyze the magnetic resonance imaging(MRI)features of multiple sclerosis(MS)patients both in the brain and the spinal cord and to explore its relationship with factors such as quality of life,disability of MS patients and so on.Methods A total of 170 MS patients confirmed clinically underwent MRI examination and answered the questionnaires of Multiple Sclerosis Quality Of Life-54 instrument,Expanded Disability Status Scale,Hamilton Anxiety Scale and Hamilton Depression Scale.Results The lesions on brain MRI were usually seen in the white matter around the lateral ventricles,the centrum ovale majus and frontal lobe.The commonly seen length of the single lesions on the spinal cord was as long as that of 1-2 vertebral bodies,but that of the fused lesions was as long as that of 4-5 vertebral bodies.The distribution of the lesions was significantly correlated with the quality of life,the degrees of the disability,anxiety and depression.Conclusion MRI examination is useful for early and better diagnosis of MS and can provide guidance for treatment,and thus can improve the prognosis and the quality of life of patients.

BACKGROUND:A large number of experiments have shown that bone marrow mesenchymal stem cels (BMSCs) have good effects on the treatment of lung disease or improvement of lung injury, and its therapeutic effect is mainly oriented to reduce the inflammatory response. OBJECTIVE: To study the effects of BMSCs combined with reduced glutathione in murine models of bleomycin-induced lung injury. METHODS:BMSCs were isolated from a male NOD/SCID mouse and cel morphology and phenotype were observed. Sixty-four female NOD/SCID mice were randomly divided into a control group, a model group, a BMSCs group and a BMSCs+reduced glutathione group (combined group). The control group received intratracheal injection of normal saline, the model group received intratracheal injection of bleomycin, and the BMSC group received BMSCs injectionvia the tail vein at 2 hours after intratracheal injection of bleomycin, and combined group received BMSCs+reduced glutathione injection via the tail vein at 2 hours after intratracheal injection of bleomycin. Al mice were kiled after 7 days, and levels of tumor necrosis factor-α, interleukin-β, malondialdehyde in lung tissue were detected and lung tissue specimens were obtained for pathological examination. RESULTS AND CONCLUSION:BMSCs were fibroblast-like cels, Positive for CD10, CD13 and CD44, but negative for CD34 and CD45. Compared with the control group, the levels of tumor necrosis factor-α, interleukin-β and malondialdehyde were increased in the model group, while decreased significantly in the BMSCs group and combined group (P < 0.05), especialy in the combined group (P < 0.05). Pathological examination showed that more serious lung injury was observed in the model group and BMSCs group than the combined group. These findings indicate that BMSCs combined with reduced glutathione can more effectively protect against bleomycin-induced lung injury.

Objective To analyze the schistosomiasis endemic situation and understand its transmission trend in Jiangling County from 2004 to 2013 so as to improving the schistosomiasis control. Methods The relevant data of schistosomiasis were collected and analyzed statistically in Jiangling county from 2004-2013. Results The human prevalence of schistosomiasis was decreased from 10.22%in 2004 to 0.63%in 2013 with the descend rate of 93.84% and the notable descend rate was 76.92%from 2009-2013. The cattle infection rate was decreased yearly from 7.59%in 2004 to 0 in 2013. The appearance rate of frames with living Oncomelaniahupensissnails and the infection rate of snails reduce by 17.53%and 100%respectively. Conclusions Af?ter 10?year control the endemic situation of schistosomiasis in Jiangling County decreases and is at a low level. However the risk factors of transmission still exist. Therefore the comprehensive control measures still should be enhanced continuously.

Objective To evaluate the development of immature oocytes after freezing-thawing by conventional cryopreservation method for mature oocytes.Methods Immature oocytes were collected from stimulated ovaries of intracytoplasmic sperm injection(ICSI)cycles.Immature oocytes were in vitro matured directly or after slow freezing-fast thawing and immunostained for tubulin and chromatin and at last visualized by confocal microscopy.Results No statistical difference was found in maturity rate between freezing groups and the controls.There was a statistically significant increase in abnormalities of chromosome(23.7% vs. 50%)and spindle(28.9% vs.53.9%)in the GV freezing group compared with the GV control(P

Objective To explore the culturing strategies,curiculum provision,courses conferring methods,teaching effects as well as the associated managerial evaluations on the basis of Sino-French cooperation on medical education with the hope of summarizing helpful suggestions to Sino-Foreign cooperation on medical education. Methods The achievements of our Sino-French cooperation on medical education were analyzed and compared in the teaching models,culturing strategies along with courses conferring processes among seven-year medical students from both English-teaching and French-teaching classes. Results Our Sino-French cooperation on medical education was featured in its distinct culturing purposes and effective teaching model.Its scientifically formulated culturing strategy found its full expression in French-teaching atmosphere.The Sino-French cooperation on medical education was consistently welcomed and favorably recommended by both faculties and students. Conclusion The Sino-French cooperation on medical education has not only gained precious experience in culturing the cutting-edge medical talents with the international visions but also conduced to fulfill the goal to establish a modernized and internationalized medical school.

Objective To explore the clinical correlation of the variation of plasma homocysteine (HCY), melatonin (MLT) and ulceative colitis (UC). Methods The clinical data of 112 UC patients was collected, and 110 normal healthy persons as control. The level of plasma HCY and MLT was detected by high pressure liquid chromatography-fluorescence detection (HPLC-FD) method. The level of plasma folate ( FA) and vitamin B12 was detected by enzyme-linked immunosorbent assay (ELISA) method. The correlation of these four indexes and UC was analyzed. Results The serum level of HCY in UC patients was significantly higher than that in normal healthy persons [(11. 27± 7.26) μmol/L vs (8. 19±4. 81) μmol/L, P = 0. 000]. The serum level of MLT in UC patients was significantly lower than that in normal healthy persons [(49. 06 + 31. 40) pg/ml vs (64. 28±41. 16) pg/ml,P=0. 008]. The serum level of FA in UC patients was significantly lower than that in normal healthy persons [(7. 64 + 1.95) nmol/L vs (9. 14 + 1.23) nmol/L, P = 0. 005]. The serum level of vitamin B12 in UC patients was significantly lower than that in normal healthy persons [(108. 64 ±32. 22) pmol/L vs (112. 64±33. 33) pmol/L, P = 0. 004]. There was no correlation between plasma HCY, MLT and UC disease activity degree, range, disease duration, erythrocyte sedimentation rate (ESR), or C reactive protein (CRP) in UC patients. There was no significant correlation between MLT and HCY in UC patients. Conclusions The serum level of HCY is higher in UC patients than that in normal control, and MLT is lower than that in normal control. However there is no significant correlation between them.

The inhibitory effects of Endostar in combination with radiotherapy in BALB/c nude mice model of human CNE2 nasopharyngeal carcinoma and the mechanism were investigated. In nude mice model of CNE2 nasopharyngeal carcinoma, the inhibitory rate and the sensitizing enhancement ratio (E/O) were calculated according to the tumor volumes in different groups. The expression of microvascular density (MVD) in tumor tissues was examined by using immunohistochemistry staining. The transcription of VEGF gene was detected by using RT-PCR. The inhibitory rate in Endostar+ radiotherapy group was higher than in other groups. In Endostar+radiotherapy group, the tumor volume was significantly decreased and the E/O ratio was 2.335, suggesting that Endostar could be a radiosensitizer. The expression of MVD of tumor tissues in Endostar+radiotherapy group was reduced significantly. The expression of the MVD in treatment groups was significantly different from that in control group (P<0.05). Compared to other groups, VEGF mRNA expression in Endostar+radiotherapy group was decreased remarkably. Endostar in combination with radiotherapy significantly inhibited the growth of CNE2 tumor. The combination therapy decreased the expression of VEGF, and inhibited tumor angiogenesis and proliferation. When combined with radiotherapy, Endostar acted as a radiosensitizer.
