OBJECTIVEThis study aims to identify the crack tip stress intensity factor of the propagation process, crack propagation path, and the changes in the shape of the crack tip by the finite element method.

METHODSThe finite element model of dentino-enamel junction was established with ANSYS software, and the length of the initial crack in the single edge was set to 0.1 mm. The lower end of the sample was fixed. The tensile load of 1 MPa with frequency of 5 Hz was applied to the upper end. The stress intensity factor, deflection angle, and changes in the shape of the crack tip in the crack propagation were calculated by ANSYS.

RESULTSThe stress intensity factor suddenly and continuously decreased in dentino-enamel junction as the crack extended. A large skewed angle appeared, and the stress on crack tip was reduced.

CONCLUSIONThe dentino-enamel junction on human teeth may resist crack propagation through stress reduction.

Objective To analyze the effects of the mumps virus on testicular function and evaluate the value of blood testosterone in acute orchitis condition and prognosis by observing the testosterone levels of peripheral blood in the mumps orchitis patients.Methods Thirty patients with acute mumps orchitis (mumps orchitis group)and 28 patients with mumps only without any major complications (mumps group)were enrolled in the study.At the same time,we selected 20 healthy males in our hospital as healthy controls.All cases were treated by ribavirin (10mg/kg). The testosterone was tested by chemiluminescence method,in 0,7,14 days respectively.The variance analysis and LSD -t test were used to compare differences of blood testosterone in each group,and Pearson method was used to analyze the correlation of blood testosterone and testicular swelling day times,blood amylase,level of neutrophils,IL -6 and CRP.Results The testosterone of acute orchitis [(1.51 ±0.26)ng/mL]was lower than mumps group and healthy controls.The difference was significant(F =99.36,P <0.01).The level of blood testosterone was significantly increased in the treatment for 14 days (t =13.03,P <0.01),and there was no significant difference compared with healthy controls (t =1.23,P =1.23).Pearson correlation analysis found that blood testosterone levels were negatively correlated with the days of testicular swelling,the levels of IL -6 and CRP(r =0.678,P <0.01 and r =0.528,P =0.000;r =0.442,P =0.000).Conclusion This study showed that MuV infection inhibited testosterone synthesis in Leydig cells.In other words,the level of blood testosterone is related to the severity of the orchitis,which can be widely used in clinical.

Bm04862 is a novel hemocyte-specific gene, which has been identified and cloned through the microarray data in silkworm, Bombyx mori. Initially, we successfully obtained the full-length cDNA sequence of Bm04862 via the rapid amplification of cDNA ends (RACE). The sequence consists of an open reading frame (ORF) with 819 bp, which could encode 273 amino acid residues. The bioinformatics analysis predicted that Bm04862 was a transmembrane protein. Furthermore, qRT-PCR analysis revealed that the expression of Bm04862 was specifically detected in hemocyte and reached a peak at L4M and PP2 stage. Bm04862 was overexpressed in Sf9 insect cells, and the cellular localization indicated that Bm04862 was specifically located in cytoplasm and nuclei membrane. Interestingly, the expression of Bm04862 increas'd dramatically after challenged with Escherichia coli for 24 hours, which predicted its potential role in the innate immune system. Overall, this study could provide the fundamental knowledge for further research.

Objective To explore the effect of traditional Chinese massage on upper limbs spasticity in stroke patients who accepted Botulinum toxin type A (BTX-A) injection. Methods 74 stroke patients with upper limbs spasticity were divided into treatment group (n=36)and control group (n=38). The control group received BTX-A injection, and the treatment group received massage after injection. Both groups received rehabilitation training after injection and were assessed with modified Ashworth scale, Fugl-Meyer assessment and modified Barthel index before and 2 weeks, 4 weeks, 8 weeks and 12 weeks after treatment. Results All the scores of assessments improved in both groups after treatment (P<0.001), and there was no significant difference between them (P>0.05). Conclusion Addition of traditional Chinese massage doesn't work more on spasticity of upper limbs after stroke when accepted BTX-A injection.

Objective To improve the canines myocardial infarction curative effect by using ultrasound targeted microbubble destruction (UTMD) combining with nuclear localization signal(NLS) peptide to increase hAng-1 gene transfection efficiency.Methods Forty-six canines were randomly divided into 4 groups (n=10 in each group) after the models of myocardial infarction were prepared.Group A were untreated control;Group B were transfected with hAng-1;Group C were transfected with UTMD+hAng-1;Group D were transfected with UTMD+NLS nuclear localization signal+hAng-1.The therapeutic agents were intravenously injected at one week after myocardial infarction in each group,and the ultrasound were irradiated at the precardium in group C and D.①Echocardiography was used before and at one week after myocardial infarction and 28 days after gene transfection.Two-dimensional echocardiography was used to detect cardiac function,the left ventricular ejection fraction,the left ventricular wall motion and the myocardial contrast echocardiography were used to detect myocardial perfusion of all canines in the four groups.②On twenty-eight days after gene transfection,mRNA and Western Blot were used to detect the expression of hAng-1.Immunohistochemistry was used to detect capillary density of peri-infarct area and microvessel density (MVD).Masson′s trichromatic staining and gross specimen were used to evaluate the degree and the area of myocardial fibrosis.The gene transfection efficiency and the curative effect of all the four groups were evaluated and compared.Results ①Before myocardial infarction,in four groups canine ventricular wall motion and cardiac function were normal,and myocardial filling defect was not showed by myocardial contrast echocardiography.At one week after myocardial infarction,the left ventricular anterior and interval walls motion and the left ventricular ejection fraction in the four groups were significantly decreased.Myocardial contrast echocardiography showed anterior and interval walls myocardial filling defect.There was no significant difference among the four groups(P>0.05);On 28 days after gene transfection the left ventricular ejection fraction in the four group were increased in an order of group A,B,C,D,there was significant difference when comparing group C and D with other groups separately(P<0.05).Myocardial contrast echocardiography showed much contrast filling in the infarction and surrounding area in group D,a little contrast filling in group C and filling defect in group A and group B,there was significant difference when comparing group C and D with other groups separately(P<0.05).②RT-PCR and Western Blot showed the hAng-1 mRNA and protein expression in group D were higher than those in the other group.There was significant difference when comparing group C and group D with other groups separately(P<0.05).③Immunofluorescence showed the capillary densities were(4.7±1.6)/mm2,(11.2±2.8)/mm2,(70.0±6.4)/mm2 and (85.3±7.0)/mm2 in group A,group B,group C and group D.The differences were statistically significant compared group C and group D with other groups (P<0.05).④Masson′s trichromatic staining and cardiac gross specimen showed that the degree and area of myocardial fibrosis were gradually reduced in an order of group A,B,C,D.Conclusions UTMD and NLS peptide could effectively transfect hAng-1 gene and it provided a novel strategy of gene treatment for ischemic heart disease.

Objective To explore the treatment effect and failure patterns associated with different clinical target volume on patients with esophageal carcinoma treated with 5-filed intensity modulated radiotherapy (IMRT), and to determine whether involved field irradiation (IFI) is practicable in these patients. Methods A total of 88 patients with esophageal carcinoma between January 2012 to June 2014 underwent IMRT in our hospital, were divided into IFI group and elective nodal irradiation(ENI) group according to the CTV range for a concurrent control study. Results One-year and two-year survival rate in IFI group and ENI group were 75.0%, 45.5% and 70.5%, 43.2% respectively (P > 0.05). Local failure rate in IFI and ENI groups was 27.3% and 22.7% respectively, distant metastasis failure rates 22.7% and 18.2% respectively and regional failure rate outside the radiation field 11.4% and 4.5%, which showed no statistical difference (P > 0.05). Subgroup analysis indicated failure outside the radiation field tended to increase for primary lesion located in the up thoracic or clinical stageⅠ in IFI group. The volume dose histogram of lung V5, V20, V30 and mean lung dose of ENI group were greater than that of IFI group, while V5 of lung and the mean lung dose had statistical difference. Conclusions The survival rate and local control rate have no significant differencein IFI group and ENI group, so IFI is feasible for some esophageal carcinoma, but it should be cautious to choose IFI for those primary lesion located in the up thoracic or clinical stageⅠ.
