Objective:To observe the clinical effect of tuina plus Baixiao moxibustion in the treatment of temporomandibular joint dysfunction syndrome (TJDS). Methods: A total of 70 TJDS patients who met the inclusion criteria were randomized into an observation group and a control group by flipping a coin, with 35 cases in each group. Patients in the observation group were treated with tuina plus Baixiao moxibustion, while patients in the control group received oral intake of diclofenac potassium (75 mg/pill), 1 pill after every dinner. Both tuina and Baixiao moxibustion were done once a day during treatment. The therapeutic evaluation was evaluated after 10 treatments in both groups. The maximum mouth opening distance and visual analog scale (VAS) were observed before and after treatment, and the therapeutic efficacy was also compared. Results: After treatment, the maximum mouth opening distance and VAS improved in both groups (all P＜0.05); both items in the observation group were superior to those in the control group (both P＜00.05). The total effective rate was 91.4% in the observation group, versus 74.3% in the control group, and the between-group comparison of the total effective rate showed statistical significance (P＜0.05). Conclusion: Tuina plus Baixiao moxibustion can effectively improve TJDS patient’s temporomandibular joint function and alleviate pain, with better efficacy than oral intake of diclofenac potassium.

Objective To explore the temporal and spatial expression pattern of tenascin-c(tnc) and tenascin-w(tnw) in zebrafish early development,to further explore the role of tenacsin in zebrafish embryo development,and the association between them.Methods Zebrafish embryos at 2 hours post fertilization(hpf),4 hpt,8 hpt,10 hpf,24 hpt,48 hpr,72 hpf and 7 days post fertilization(dpf) were collected to extract RNA for reverse transcription-polymerase chain reaction(RT-PCR) and fix the embryos at different stages for in situ hybridization.Temporal and spatial expression pattern of tnc and tnw on different stages of zebrafish early development was observed.Results tnc and tnw all expressed in zebrafish from 24 hpf to 7 dpf,but did not expressed from 2 hpf to 10 hpf.Tnc expressed at pharyngeal arch,notochord,somite in 24 hpf,then weakly expressed at somite,but highly expressed at otic vesicle,pectoral fin and hindbrain in 48 hpf,and tnc was expressed at hindbrain,pharyngeal and notochord and disappeared at somite and pectoral.tnw expressed at hindbrain,midbrain and otic vesicle in 24 hpf,expressed at somite,notochord,hindbrain,otic vesicle and pharyngeal in 48 hpf.In 72 hpf,tnw expressed weakly at somite and notochord.Conclusions Zebrafish tnc and tnw have special temporal and spatial expression pattern,and share partial overlapping expression pattern.

Objective To explore the expression pattern of tenascin-c(tnc)gene in zebrafish embryo abnormal development which was induced by ethanol,and to further understand the function of tnc gene in embryo develepment.Methods Zebrafish were treated with ethanol at different concentration from 100 to 500 mmol/L,and embryos at 24 and 48 hours were collected and fixed,then tnc expression pattern was observed by in situ hybridization and reverse transcriptase-polymerase chain reaction(RT-PCR).Results The result of RT-PCR showed that ethanol at 100 and 200 mmol/L could increase the expression of tnc,while the result of in situ hybridization showed that,while ethanol at 300 mmol/L and above decrease the expression of tnc in presumptive position at 24 hours,and ethanol at 100 mmol/L and above caused increase expression of tnc in zebrafish heart.Conclusions tnc is increased when treated with 100 and 200 mmol/L ethanol and is presented in the abnormal development of hearts of zebrafish,which can promote the normal development of embryos in some degrees.The expression pattern of tnc in pathologic state is highly conserved in all vertebrate,and in adult and embryos as well.

Objective To explore the differences in the strength of the nodes in the brain white matter weighted networks between the male patients with paranoid schizophrenia and male healthy controls, and to analysis the integrity of the white matter fiber tracts that connected to the different brain regions and its relationship with the course of disease. Methods Diffusion tensor imaging (DTI) data were obtained from 25 male patients with paranoid schizophrenia and 26 male healthy controls. The whole brain was parcellated into 90 regions by using the anatomical label map. Tractography was performed in the whole brain of each subject to reconstruct white matter tracts using the FACT algorithm. The brain white matter weighted networks were then constructed using the complex network theory. Results The strength of the nodes in the networks of schizophrenia significantly decreased in the right thalamus (P=0.03, corrected) and the right hes?chl gyrus (P=0.04, corrected). Negative correlation was found between the strength of the right thalamus and the course of disease (r=-0.45, P=0.03). Conclusion The integrity of the white matter fiber tracts connected to the thalamus and tem?poral lobes in the male paranoid schizophrenia is impaired. The lesion of fiber tracts connected to the thalamus is related with the course of disease.

Objective To explore the differences of the connectivity strength,the clustering coefficient and the local efficiency of the nodes in the brain structural networks in the depression and healthy subjects and then analyze the mode of the local connections of the brain regions and their local efficiency of the transmission of information and their relationship with the severity of the disease in the depression.Methods The Diffusion Tensor Imaging data were obtained from 24 depression patients and 25 healthy controls.The whole cerebral cortex was parcellated into 90 regions by the anatomical label map.Tractography was performed in the whole cerebral cortex of each subject to reconstruct white matter tracts of the brain using the fiber assignment by continuous tracking (FACT) algorithm.And then the brain structural networks were constructed using the complex network theory.The local topological properties of the brain structural networks of the depression and healthy were examined by two sample t-test.Results The local efficiency of the nodes of the networks in depression decreased significantly (the left middle frontal gyrus (orbital part):0.64±0.30,the left hippocampus:0.57±0.07,the right parahippocampal gyrus:0.50±0.15) compared with the healthy (0.88±0.10,0.64±0.06,0.66±0.13 respectively,P=0.00098,0.00039,0.00017,survived critical FDR threshold for multiple comparisons) ; and the clustering coefficient of the nodes of the networks in depression (the left middle frontal gyrus (orbital part):0.14±0.07) decreased significantly when compared with the healthy (0.22±0.06,P=0.000030,survived critical FDR threshold for multiple comparisons).Significant negative correlation was found between the local efficiency of the left middle frontal gyrus (orbital part) and the total scores of HAMD-17 in the depression (r=-0.48,P=0.02).Conclusion The degree of the localization and the local efficiency of the information transmission of the frontal lobe are decreased.The local efficiency in the information transmission in the hippocampal is also decreased.And the local efficiency of the frontal lobe is negatively related with the severity of the disease in the depression.

Objective To explore the differences of the degree and distribution of hub regions of the brain structural networks between the schizophrenia and healthy and then analysis the importance of brain regions in the information transmission in across the whole brain.Methods The diffusion tensor imaging data were obtained from 22 schizophrenia patients and 24 healthy controls.The whole cerebral cortex was parcellated into 90 regions by the anatonical label map.Tractography was performed in the whole cerebral cortex of each subject to reconstruct white matter tracts of the brain using the fiber assignment by continuous tracking (FACT) algorithm.And then the brain structural binary networks were constructed using the complex network theory.The average degree of the network and the degree of the nodes in the network between the brain structural networks of both groups were examined by two sample t-tests.Results The average degree of the brain structural network in the patient group (7.82±0.56) decreased significantly when compared with the control group (8.17 ±0.56; P=0.04).The degree of the nodes in the brain structural network of the patient group (the left hippocampus:11.41 ± 1.84; the left parahippocampal gyrus:6.41± 1.33 ; the left calcarine fissure:11.50±2.97 ; the left fusiform gyrus:8.27± 1.83) decreased significantly when compared with the control group (14.43±2.26; 8.54±2.15; 14.79±2.80; 10.25± 1.36; all P＜0.01,survived critical FDR threshold for multiple comparisons).And the distribution of the hub regions in the temporal and occipital lobes of the patient group was difference from that of the control group.Conclusion The importance of the hippocampus and the brain regions in the occipital lobe is decrease for the information transmission across the whole brain.The damage of the topological properties of these brain regions maybe related to the disorder of the transmission and integration of information in the brain of the schizophrenia.
