Objective To describe the characteristic MR findings in the brain in patients with amyotrophic lateral sclerosis (ALS), and to assess the diagnostic value of conventional MR imaging and fractional anisotropy (FA) of diffusion tensor imaging (DTI). Methods Conventional MR imaging was performed in 14 clinically proved ALS patients and 12 age-matched normal controls. Contrast enhanced MR images were acquired in 2 patients. Axial and coronal DTI scans were performed in 10 patients and 12 normal controls with SE-EPI sequence. The b value was 1 000 s/mm 2, the number of diffusion sensitive gradient direction was 25. For quantitative assessment of the corticospinal tract (CST), FA value of bilateral CST was measured at the level of posterior limb (PL) of the internal capsule (IC) and the cerebral peduncle of the midbrain, respectively, and statistical analysis was performed. Results Focal slight low signal intensity on T 1WI and high signal intensity (hyperintense to gray matter) on T 2WI was demonstrated in 6 ALS cases (42.9%) in bilateral PL of the IC, and the high signal was longitudinally continuous from the PL to the cerebral peduncle on T 2WI coronal plane, corresponding to the course of CST. In another 8 ALS cases (57.1%), the focal slight low signal intensity on T 1WI and slight high signal intensity (isointense to gray matter) on T 2WI was revealed in bilateral PL of the IC. No abnormal contrast enhancement was detected in the 2 cases. In control group, the focal slight low signal intensity on T 1WI and slight high signal intensity (isointense to gray matter) on T 2WI was demonstrated in all 12 subjects in bilateral PL of the IC. FA values of the patient group were significantly lower than that of the control group at the level of the PL of the IC (F=7.38, P

Objective To investigate the effects of alantolactone on cell proliferation,cell-cycle and cell cycle-related proteins in human chronic myelogenous leukemia drug-resistant cell line K562/ADR.Methods K562/ADR cells were treated with 0,1.0,2.0,4.0,6.0,8.0,and 10.0 μmol/L of alantolactone for 12,24 and 48 h,with its cell viability analyzed by MTT assay.Flow cytometry was used to examine the effect of alantolactone on the cell-cycle of K562/ADR cells.The cell cycle-related proteins were analyzed by using Western blot after treatment with alantolactone.Results The results of MTT showed that alantolactone effectively inhibited the proliferation of K562/ADR cells in dose and time-dependent way,and the IC50 value of alantolactone in K562/ADR cells was about 5 μmol/L.Flow cytometric analysis displayed that alantolactone could arrest cell cycle at G2/M phase.The percentage of accumulated cells in the G2/M phase was increased from (15.8±1.7) ％ in the control group to (21.0±2.4) ％,(26.4±2.7) ％,and (30.1±3.9) ％ in cells treated with 2.5,5.0,and 7.5 μmol/L of alantolactone for 24 h,respectively (P ＜ 0.05).Alantolactone significantly decreased the expression of CDK1 and CyclinB1 and increased the expression of cyclin-dependent kinase inhibitor p21.Meanwhile,the treatment of K562/ADR with alantolactone led to a dose-dependent decrease in bcr-abl protein levels.Conclusion Alantolactone can significantly inhibit the proliferation and cell-cycle arrest in G2/M phase of K562/ADR cells,in which mechanism may be associated with the regulation of cell cycle-related proteins and downregulation of bcr-abl protein.

Objective To summarize the effect of laparoscopic repair of acute gastric perforation. Methods Patients with acute gastric perforation underwent laparoscopic repair and abdominal drainage under intravenous- inhalation general anesthesia after a histological biopsy. Results Forty-six patients with acute gastric perforation were successfully operated.Of which, 6 patients with pylonic perforation, 37 patients with perforation in the front wall of gastric antrum, 3 patients with perforation in stomach body. Thirty-three cases were received frozen section biopsy, only 1 case showed a cancer in the lesser curve of stomach body. There was no complications occurred and no operative mortality in this series. Of the 45 benign ulcers patients,31 patients were discharged 7 days after the operation, 14 patients were discharged 2 weeks after medication treatment.Three months after operation the symptoms of the 45 patients disappeared totally,they had normal diet,and got body weight 1-3kg. Pathological examination showed that no malignant cell was found in 45 benign ulcer patients. The cancer patient was discharged 9 days after operation and refusing to further treatment. Conclusions Laparoscopic repair is a safe mini-invasive method, and it isn′t breach the surgical principles,it allows the patients recover quickly and with less complications. The intraoperative biopsy can prevent misdiagnosis of cancer. It is an effective treatment for acute gastric perforation and worthy to be widely used.

Objective To evaluate the correlation of the single nucleotide polymorphisms (SNPs) in CDH13 with non-small cell lung cancer (NSCLC) . Methods 115 patients with NSCLC and 110 healthy controls were included in present study. Two SNPs (rs11646213 and rs7195409) in CDH13 were genotyped using TaqMan method. The association of these two SNPs with NSCLC was calculated and assessed. Results The genotypic and allelic frequencies of rs11646213 showed significant difference between NSCLC patients and the control group (P<0.05), (OR=0.464, 95% CI:0.273~0.789) . The genotypic and allelic frequencies of rs7195409 showed significant difference between the stage I+II and stage III+IV groups (P<0.05), (OR=0.491, 95% CI:0.243~0.991) . Conclusions The rs16146213 has a strong association with NSCLC and G allelic showed a protective effect. The rs7195409 has a strong association between stage I+II and III+IV in NSCLC, and G allele may play a protective role in the development of NSCLC.

Objective To investigate the malaria knowledge of CDC staff and their demands on related training in malaria non⁃endemic areas，so as to provide the reference for planning the appropriate curriculum. Methods All the participants who were the staff of county CDCs all over Qinghai Province and attended the provincial training workshop were surveyed. A self⁃administered questionnaire survey was carried out and the data was statistically analyzed. Results A total of 115 participants were involved in this survey. They were mostly（85.21%）from county CDCs. The general knowledge of malaria among the respondents was well，and the average rate of correct answers was 70.35%. However，the answers to the general knowledge of malaria and anti⁃malaria treatment were not well enough. The rates of correct answers were 61.96% and 48.99% respectively. The differences among the groups of job title ranking，department of working and level of CDC were not significant（F = 0.13-2.02，all P > 0.05）. The number of correct answers was significantly increased after the training course. The average score after the training was 79.20±15.16 while the pre⁃training score was 70.34±17.46（t = 3.86，P < 0.05），especially in the answers to general malaria knowledge and malaria surveillance and response（t = 4.30，4.97，both P < 0.05）. The general knowledge of malaria was considered as the most need of training as 80% of the respondents voted“Yes”，according to the demand analysis. There was no significant difference among the different groups（F = 0.61-3.11，both P > 0.05）. Conclusion The malaria knowledge is well mastered by the staff of CDCs in Qinghai Province，and the further training courses are requested and addressed in the target areas such as general malaria knowledge，anti⁃malaria treatment，malaria surveillance and response.
