AIM:To investigate the changes of aryl hydrocarbon receptor (AhR) in the process of cardiomyo-cyte hypertrophy induced by high glucose , and to explore its potential mechanisms .METHODS: The rat cardiomyocytes (H9c2 cells) were divided into normal glucose group , high glucose group, DMSO group and resveratrol (an AhR antago-nist) group.The content and distribution of AhR were observed with immunofluorescence staining .The myocardial cells were stained with rhodamine-labeled phalloidin to visualize cytoskeleton , and the cell surface area were determined after im-aging by fluorescence microscopy .The generation of reactive oxygen species ( ROS) in the cardiomyocytes was measured u-sing a fluorescent probe DCFH-DA.The mRNA expression of AhR , CYP1A1, atrial natriuretic peptide ( ANP) and brain natriuretic peptide ( BNP) were evaluated by real-time quantitative PCR ( RT-qPCR).The protein levels of AhR, CYP1A1, ANP and BNP were assessed by Western blot .RESULTS:AhR was constitutively presented in the cytosol un-der normal-glucose condition and was translocated to the nuclei under high-glucose condition .High glucose induced cardiac hypertrophy , and increased ROS generation .Significant reductions in the cell size and ROS generation were observed after treated with resveratrol.The expression of AhR, CYP1A1, ANP and BNP at mRNA and protein levels in high glucose group was increased as compared with normal glucose group and resveratrol group , and the above-mentioned indexes signifi-cantly decreased in resveratrol group as compared with DMSO group .CONCLUSION: High glucose-induced cardiac hy-pertrophy increases AhR expression , which may be involved in the maintenance of glucose homeostasis in the cardiomyo-cytes.AhR translocation to the nucleus induced by high glucose results in the increases in CYP 1A1 expression and ROS generation, which may be an important mechanism of high glucose-induced cardiomyocyte hypertrophy .

Objective : To investigate the awareness of human papillomavirus ( HPV ) vaccine and willingness to vaccinate daughters among parents of primary and middle school students, so as to provide the reference for the promotion of HPV vaccine in primary and middle school girls. Methods : Using multi-stage stratified cluster sampling method, the parents of girls in in Grade Four to Nine from schools in Gongshu District of Hangzhou, Xiuzhou District of Jiaxing and Wuxing District of Huzhou were selected. A questionnaire survey was conducted to collect demographic information, HPV vaccine related knowledge and willingness to vaccinate daughters with HPV vaccines. The multivariate logistic regression model was used to analyze the influencing factors for the willingness to vaccinate daughters with HPV vaccines among parents. Results : Totally 1 500 questionnaires were sent out, and 1 466 were effectively collected, with an effective rate of 97.73%. There were 313 fathers responded, accounting for 21.35%; and 1 153 mothers responded, accounting for 78.65%. The awareness rate of HPV vaccine was 16.81%. The rate of willing to vaccinate daughters with HPV vaccines was 49.86%. The multivariate logistic regression analysis showed that the patients who ever vaccinated daughters with self-paid vaccines ( OR=1.935, 95%CI: 1.473-2.541 ), knew cervical cancer ( OR=1.424, 95%CI: 1.065-1.904 ), knew HPV vaccine dose ( OR=1.672, 95%CI:1.216-2.301 ), knew the best vaccination period ( OR=1.392, 95%CI: 1.032-1.876 ), knew the need of cervical cancer screening even after vaccination ( OR=1.596, 95%CI:1.227-2.075) were more willing to vaccinate daughters with HPV vaccines, while the parents who thought HPV vaccine expensive ( OR=0.154, 95%CI: 0.099-0.240 ) were less willing to vaccinate daughters with HPV vaccines. Conclusions The rates of HPV vaccine awareness and willingness to vaccinate daughters are 16.81% and 49.86% among parents of primary and middle school students. Their knowledge of HPV vaccine and the price of the vaccine may affect their willingness to vaccinate daughters.

Objective This meta-analysis aims to identify consistent results of vulnerable brain regions through the existing resting-state fMRI studies, thus exploring the changes of neural spontaneous brain activity in type 2 diabetes mellitus (T2DM) patients. Methods A systematic analysis of studies on brain resting-state changes in T2DM patients using ALFF, fALFF and ReHo analysis. The meta-analysis was based on the activation likelihood estimation method, using the software of Ginger ALE 2.3. Results Ten studies from 7 references (188 T2DM patients and 170 healthy controls) were included. Based on the analysis of ALFF and ReHo data, this meta-analysis identi fied the robust reduction of resting-state spontaneous brain activity in T2DM patients, including the left lingual gyrus of occipital lobe, right cerebellum posterior lobe,left postcentral gyrus and right insula(cluster size= 800,488,368,256 mm3,P<0.05 after FDR correction),while no increased spontaneous brain activation was found in any regions.The meta-analysis from ReHo studies showed reduced resting-state spontaneous brain activity in the left lingual gyrus of occipital lobe,left postcentral gyrus,right insula and posterior cingulum/lingual gyrus(cluster size=832,368,280,232 mm3,P<0.05 after FDR correction),while no increased spontaneous brain activation was found in any regions. Conclusion This meta-analysis study using the activation likelihood estimation method demonstrated that the resting-state spontaneous brain anomalies in T2DM patients might contribute to exploring machenism underlying diabetic encephalopathy.

Objective: To study the biomechanical property and histocompatibility of acellular porcine fascia so as to supply a new substitute material for tissue repair. Methods: Samples of normal porcine fascia, acellular porcine fascia and normal human fascia were prepared for histological and biomechanical examination. Xenogeneic fresh porcine fascia, acellular porcine fascia and allogeneic rabbit fascia were implanted into the back of rabbit. Tissues were taken for HE staining and histocompatibility test. Results: Histological examination showed that the cellular components which elicit immune rejections had been removed in the acellular porcine fasciam, with the complete extracellular matrix reserved. Arrangement of collagen fiber was loose in the acellular porcine fascia. The biomechanical performance test of the three samples showed that there was no significant difference in the extreme tensile strength (4.47±0.54) MPa, (4.49±0.91) MPa, (4.79±1.35) MPa for acellular porcine fascia, normal porcine fascia and normal human fascia respecively, P>0.05). There was no significant difference between acellular porcine fascia extracellular matrix and porcine fascia with the cell in breaking elongation (501.83%±52.01%, 661.17%±200.28%, P>0.05). However, there was a significant difference in the breaking elongation between human fascia (98.08%±26.02%)and the other 2 kinds of porcine fascia (P<0.01). Histocompatibility test showed the local reactions of the acellular porcine fascia group were weaker than the normal porcine fascia group. Conclusions With sound preparativemethod, the acellular porcine fascia has good biomechanical property and histocompatibility and may serve as a good alternative material for tissue repair.

Objective: To understand the current situation of toilet facilities among rural primary schools and toilet-using behavior among primary students,and to provide a reference for improving school environment. Methods: Totally 149 students in 2 rural non-boarding primary schools in northern China were selected. and on-site observation and questionnaire survey were used to obtain the current situation of toilet hygiene, toilet time and toilet behavior, as well as feelings towards school toilet. The results of the survey were statistically analyzed by using SAS 9.4. Methods: Both two schools were deep pit latrine, the number of pit in female toilets is lower than the requirements of the “Code for design of school”, and the urinal trough and the number of pit in male toilet meet the standard requirements. The average total time of toilet-using was (28.46±11.72)s for boys and (42.48±15.52)s for girls, the difference was of significant difference (t=-7.96, P<0.01). The average actual time of toilet-using is (24.27±9.13)s for boys and (24.69±9.40)s for girls, with no statistical difference. The result showed that school 2 was better than school 1 in the behavior of urinating frequency in toilet, queuing when using toilet, and the way to express needs of toilet-using in class(χ2=11.70,27.19,17.74,P<0.05); senior students use less toilets than lower grade students. The main complains for students in school toilet hygiene is its bad smell(χ2=5.28，13.18，P<0.05). Conclusion Primary school students in northern China always take bathroom breaks in the morning, and the average time of toilet-using is different from that of adults. Senior students are more willing to express their toilet needs than lower grade students. Students are not satisfied with the hygiene of school toilets, and the toilet experience is poor.

Objective To investigate the effect of transcription factor specific protein5(Sp5)silencing on Wnt signaling pathway correlated factors and cell proliferation ability in mouse embryo palatal mesenchymal cells(mEPMCs).Methods mEPMCs of 14.5 d pregnant C57BL/6J mice were isolated and cultured in vitro.Cell source was identified by immunofluorescence staining.Lentivirus transfection technique was used to silence the expression of Sp5 gene in mEPMCs,and the transfection efficiency was verified by Western blot assay.Follow-up experiments were set up with the blank control group,the no-load virus group and the slience group(the Sp5-shRNA group).The protein and mRNA expression levels of β-catenin,GSK-3β,Wnt3a and CyclinD1 were detected by Western blot assay and RT-qPCR after transfection for 72 h in each group.Cell proliferation capacity was detected by CCK-8.The proliferation rate of 5-Ethynyl-2'-deoxyuridine(EdU)positive cells was detected by immunofluorescence assay.Cell cycle was detected by flow cytometry.Results mEPMCs were successfully isolated,and Sp5 expression was silenced.Western blot and RT-qPCR results showed that the protein and mRNA expressions of β-catenin,GSK-3β,Wnt3a and CyclinD1 were significantly higher in the Sp5-shRNA group than those in the blank control group and the no-loaded virus group(P<0.05).The proliferative ability and the proliferative rate of EdU positive cells were higher in the Sp5-shRNA group than those in the blank control group and the no-loaded virus group(P<0.05).The proportion of mEPMCs in S phase was higher in the Sp5-shRNA group than that in the blank control group and the no-loaded virus group(P<0.05).Conclusion Sp5 in silenced mEPMCs can participate in palate development and promote the proliferation of mEPMCs by regulating Wnt signaling pathway.

Bombyx mori is a lepidopteran insect with important economic value. Bombyx mori nucleopolyhedrovirus (BmNPV) causes huge economic loss to silkworm industry in China every year. The objective of this study is to determine the anti-BmNPV mechanism of Bombyx mori strain NC99R, and to provide a basis for understanding the molecular mechanism of the silkworm resistance strain. The normal control Dazao (DZ) strain and the NC99R resistant strain were fed with occlusion bodies (OB). The median lethal dose (LD50) analysis of the DZ and NC99R showed that the LD50 of DZ was 1.2×10⁵ OBs/larva, while NC99R was 1.8×10⁶ OBs/larva. The LD50 of the NC99R was about 15 times higher than the DZ. The mortality of DZ and NC99R were analyzed, which were fed with 1×10⁶ OBs/larva and injection with 1×10⁶ BVs/larva. The results showed that the death peak of DZ was concentrated in the 4th to 6th day. And the death peak of NC99R was concentrated in the 6th to 8th day, with a delay of 1-2 days compared with the control. The BmNPV DNA copy number showed that the BmNPV genome in DZ proliferated rapidly. The copy number of BmNPV DNA in NC99R were increased slowly after oral infection and body injection. HE staining showed that midgut tissue has no significant difference between DZ and NC99R in the early stage of oral infection. At 96 h p.i., the nucleus of DZ midgut became larger and shedding. The NC99R had enlarged nuclei, but the cells were still arranged neatly. Finally, the expression of virus genes in different periods were analyzed by RT-PCR. The results indicated that the immediate early gene ie-1 expression levels began to down-regulate after 24 h p.i.. The early, late, and extremely late genes were also down-regulated, and finally maintained at a lower expression level.

Motor timing is an important part of sensorimotor control. Previous studies have shown that beta oscillations embody the process of temporal perception in explicit timing tasks. In contrast, studies focusing on beta oscillations in implicit timing tasks are lacking. In this study, we set up an implicit motor timing task and found a modulation pattern of beta oscillations with temporal perception during movement preparation. We trained two macaques in a repetitive visually-guided reach-to-grasp task with different holding intervals. Spikes and local field potentials were recorded from microelectrode arrays in the primary motor cortex, primary somatosensory cortex, and posterior parietal cortex. We analyzed the association between beta oscillations and temporal interval in fixed-duration experiments (500 ms as the Short Group and 1500 ms as the Long Group) and random-duration experiments (500 ms to 1500 ms). The results showed that the peak beta frequencies in both experiments ranged from 15 Hz to 25 Hz. The beta power was higher during the hold period than the movement (reach and grasp) period. Further, in the fixed-duration experiments, the mean power as well as the maximum rate of change of beta power in the first 300 ms were higher in the Short Group than in the Long Group when aligned with the Center Hit event. In contrast, in the random-duration experiments, the corresponding values showed no statistical differences among groups. The peak latency of beta power was shorter in the Short Group than in the Long Group in the fixed-duration experiments, while no consistent modulation pattern was found in the random-duration experiments. These results indicate that beta oscillations can modulate with temporal interval in their power mode. The synchronization period of beta power could reflect the cognitive set maintaining working memory of the temporal structure and attention.
