It is advocated on clinical medical education to let students contact clinical diagnosis and treatment earlier, visiting more patients and promoting the ratio of visitation and course. But as more and more students flood into university, clinical visitation has turned into a difficulty to improve students' ability. To resolve this problem, we have made some efficient practice and exploration.

ObjectiveTo assess a simple apparatus measuring displacement of pelvis in clinical application.MethodsTwo testers measured the displacement of pelvis of 20 healthy young subjects moving their body forward, backward, leftward and rightward in standing position. The reliability of inter- and intra-tester was tested with intraclass correlation co-efficiency (ICC). And the validity between this method and Functional Reach Test (FRT) was tested.ResultsThe ICC of inter- and intra-tester were 0.91～0.97 and 0.94～0.98 respectively, and correlated with FRT (r=0.88, P<0.01).ConclusionThis simple apparatus can be used in a balance test.

Some factors may induce accidents during physiotherapy for stroke patients. This article would summarize the general risk factors and discuss the management.

The deficiency theories of dyslexia are quite contradictory and the cross-cultural studies in recent years mainly focused on whether the dyslexics among cultures shared the same cognitive profile or just based on the language. This study used Near-Infrared Spectroscopy (NIRS) imaging to measure the regional cerebral blood volume (BV) and the changes of cerebral activation in the left prefrontal cortex of 12 Chinese dyslexic children and their 12 age-matched normal controls during the Paced Visual Serial Addition Test (PVSAT). Results showed that the scores of PVSAT of dyslexic children were significantly lower than those of the normal children (t=3.33, P<0.01). The activations of the left prefrontal cortex in the normal group were significantly greater than those of dyslexic children (all P<0.01). Our results indicated that Chinese dyslexia had a general deficiency in working memory and this may be caused by the abnormal metabolic activity of brain blood volume in the left prefrontal cortex and the deficits in brain function might be the basis of neuropathology of Chinese dyslexia. Present study supports the difference on brain activation of dyslexics from different languages may be caused by the same cognitive system related to reading.

Objective To study the anti-tumor effect of the proteoglycan extracted from abalone viscera (AVPF-I). Methods Hepatic carcinoma cell H22-bearing mice were randomized to negative control (physiological saline), positive control (cyclophosphamide) and three doses of AVPF-I groups. The tumor growth, cell mediated immune function including lymphocyte proliferation, phagocytosis of peritoneal macrophage, NK cell activity, and the level of serum TNF-?,IL-1and IFN-?were detected. Results A significant inhibition of the tumor growth was observed in the AVPF-I group(P

Objective:To investigate the expression of microRNA (miR)-938, its effect on cell proliferation and its regulatory mechanism in hepatocellular carcinoma (HCC).Methods:HCC and paracancerous tissues were collected from 40 patients with HCC who underwent surgical resection in the Second Affiliated Hospital of Nantong University from January 2015 to June 2019, including 25 males and 15 females, with an average age of 61.4 years. HepG2 cells in the miR-938 overexpression group were transfected with miR-938 mimics, and the negative control group was transfected with the negative control sequence. Cell proliferation was detected by kit, the expression of miR-938 and the succinate dehydrogenase complex subunit D (SDHD) was detected by fluorescence quantitative polymerase chain reaction, and SDHD protein expression was detected by Western blot. The target genes of miR-938 were verified by dual luciferase reporting.Results:The relative expression of miR-938 in HCC tissues was (0.060±0.002), which was higher than that in adjacent tissues (0.030±0.002), and the difference was statistically significant ( P<0.05). The mRNA relative expression of SDHD in HCC tissues was (0.028±0.002), lower than that in adjacent tissues (0.062±0.002), and the protein expression of SDHD in HCC tissues was (0.963±0.008), lower than that in adjacent tissues (1.083±0.037), with statistical significance (both P<0.05). The proliferation activity of miR-938 overexpression group was significantly higher than that of negative control group, and the difference was statistically significant ( P<0.05). MiR-938 significantly inhibited the luciferase activity of SDHD wild-type 3’-untranslated regions. In the overexpression miR-938 cells, SDHD mRNA and protein levels were significantly lower than those in the negative control group ( P<0.05). Conclusion:MiR-938 was highly expressed in HCC tissues. MiR-938 promoted the proliferation of HCC cells by inhibiting the expression of SDHD.

Objective To determine the purity,composition and antitumor activities of polysaccharide AHP-12 from abalone harslet.Methods Its purity was checked by HPLC with TSK-GEL G4000PWXL column and agarose gel electrophoresis;Molecular weight was determined by gel filtration chromatography;Sulfate content was identified by gelatine nephelometry and aminohexose content by chromatometry;Gas chromatograph was applied to determine monosaccharide composition;Antitumor activities were investigated by MTT method.Results AHP-12 from abalone harslet was a homogeneous polysaccharide both measured by molecular weight and electric property;The molecular weight was about 3?105;It was contained sulfate 13.07% and aminohexose 4.98%;AHP-12 was composed of rhamnose,fucose and galactose(the ratio in mole is 1∶2.2∶1.7);the activity determined by MTT method showed it could hamper the growth of HeLa cell.Conclusion AHP-12 was extracted and purified from abalone harslet.It was a homogeneous polysaccharide,which contained sulfate and aminopolysaccharide,and with weak antitumor activities in vitro.

ObjectiveTo explore influence of emergency nursing process reengineering on the satisfac-tion degree of patients, quality of rescue, rescue time and success rate of rescue. MethodsEvidence-based nursing method was used for emergency nursing process reengineering. The first 30 types of acute and sever diseases and the first 6 large emergency events in 2008 were chosen as the rescue objectves, and they received new emergency nursing process. Influence of classic emergency nursing process in 2007 was retrieved and revalued. The satisfaction degree of patients, quality of emergency nursing and success rate of emergency before and after process reengineering were compared and analyzed. ResultsCompared with that before process reengineering, the satisfaction degree of experts, doctors and nurses, and patients was higher, the quality of emergency nursing greatly improved, the rescue time was less, and the success rate of rescue was higher after process reengineering. ConclusionsEmergency nursing process reengineering was more hu-man oriented. It can rescue patients with acute and severe diseases with lest time, reduce disputes between nurses and patients. It is worthy of application in clinic and the process should be reengineered and im-proved constantly in the future.
