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.

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.

ObjectiveTo investigate the expression of heme oxygenase-1 (HO-1) in lung tissue of mice with acute paraquat poisoning, and discuss its pathological mechanism.Methods Fifty-eight healthy male mice were randomly divided into control group (n = 8) and poisoned group (n = 50). The mice in poisoned group were lavaged with 20% paraquat (50 mg/kg), and those in control group with equal amount of normal saline. The mice were sacrificed on the day of experiment in control group, and those in poisoned group at 6 hours and 1, 3, 7, 14 days after poisoning. The lung tissue was harvested to observe the changes in pathology of lung with hematoxylin and eosin (HE) staining. The positive expression of HO-1 was determined with immunohistochemistry, and the protein expression of HO-1 was determined with Western Blot. The contents of superoxide dismutase (SOD) and malonaldehyde (MDA) were determined.Results The mice showed shortness of breath and signs of exhaustion 1 hour after poisoning, getting worse on 3-5 days, but returned to normal 14 days after poisoning. Under the light microscope, it showed that the control group had no significant pathological changes in lung tissue. One day after the ingestion, pulmonary alveolar structure disorder, obvious hemorrhage, edema and infiltration of inflammatory cells were found. At 3 days, the pathological changes in the lung tissue were more pronounced. They were less pronounced on 7 days, and inflammatory changes disappeared on 14th day, but alveolar structure disorder remained. Immunohistochemical test showed that HO-1 was seldom expressed in the lung tissue, and a little amount was expressed in the mucosal epithelial cells of the airway in control group. It was shown that inflammatory cell and endothelial were mainly distributed in the mucosal epithelial cells of airway 1 day after poisoning followed by a gradually decrease tendence, and came to normal level of control group 7 days after poisoning. It was shown by Western Blot that HO-1 (gray value) in lung tissue increased 6 hours after poisoning (2.438±0.467 vs. 0.475±0.167,P< 0.01), peaked at 1 day (9.200±0.940 vs. 0.475±0.167,P< 0.01), continued to increase till 7 days after poisoning, and it lowered to normal level thereafter (0.825±0.260 vs. 0.475±0.167,P> 0.05). The SOD activity (μU/L) in lung tissue was lowered 6 hours after poisoning, and it was significantly lower than that of control group (649.681±13.951 vs. 1 167.051±15.744,P< 0.01), and it continued to decrease up to 14 days after poisoning (859.733±121.079 vs. 1 167.051±14.744,P< 0.01). MDA content (μmol/L) in the lung tissue homogenate was elevated 6 hours after poisoning with significant difference compared with that of the control group (4.542±0.266 vs. 3.705±0.176,P< 0.01). It peaked on day 1 (5.956±0.281 vs. 3.705±0.176,P< 0.01), then it declined and reached normal level 3 days after poisoning (4.134±0.168 vs. 3.705±0.176,P> 0.05).Conclusion HO-1 expression was increased significantly in lung tissue of mice with acute paraquat poisoning, which may be considered as an important protection mechanism against paraquat poisoning.

Objective:To explore the clinicopathologic features of 112 patients with mantle cell lymphoma (MCL). Methods:Da-ta from 112 MCL cases were collected, and immunohistochemical assay was conducted. A break in the CCND1 gene was detected by fluorescence in situ hybridization (FISH). The t-test was used in the statistical analysis. Results:All tumor cells in the 112 cases ex-pressed B cell-related antigen, including 1 blastoid subtype and 1 polymorphic subtype. Among all the cases, 106 expressed CD5 and 104 expressed cyclinD1. A break in the CCND1 gene was not found in 3 cases with CD5-MCL. IgH/CCND1 polyploid was found in 2 classical cases. Conclusion:MCL is a type of special immunophenotypic B-cell lymphoma. The prognoses of blastoid and polymorphic subtypes are poor. Special subtypes should be classified during diagnosis.
