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.

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 study the method and effect of lateral arm free flap in reconstruction of severe atresic eye socket.Methods Forteen cases of severe atresic eye socket,from June,2011 to June,2013,were repaired by lateral arm free flap.The flaps were designed and harvested as drop shape with size about 6 cm × 10 cm and then were removed epidermis except distal 6 cm × 6 cm area which were transferred to orbit for eye socket reconstruction.The remaining fascia and dermis were filled to augment temporal defect.Superficial temporal artery was anastomosed with posterior branch of radial collateral artery in 14 cases and superficial temporal vein was anstomosed with radial collateral vein in 11 cases,with middle temporal vein in 3 cases.Results All 14 cases lateral arm free flaps survived with no donor site morbidity.Followed up for 1 year to 3 years,artificial eye could be fitted satisfactorily and temporal contour improved.Conclusion Lateral arm free flap is a recommendable option for severe atresic eye socket reconstruction because of concealed donor site scar,proper volume,matched vascular caliber and minor donor site morbidity.

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.
