Abstract
BACKGROUND Curcumin nicotinate (Curtn), derived from curcumin and niacin, reduces serum LDL-C levels, partly due to its influence on PCSK9. This study investigates IDOL's role in Curtn's lipid-lowering effects. OBJECTIVE To elucidate Curtn's regulation of the IDOL/LDLR pathway and potential molecular mechanisms in hepatocytes. METHODS Differential metabolites in Curtn-treated HepG2 cells were identified via LC-MS. Molecular docking assessed Curtn's affinity with IDOL. Cholesterol content and LDLR expression effects were studied in high-fat diet Wistar rats. In vitro evaluations determined Curtn's influence on IDOL overexpression's LDL-C uptake and LDLR expression in hepatocytes. RESULTS Lipids were the main differential metabolites in Curtn-treated HepG2 cells. Docking showed Curtn's higher affinity to IDOL's FERM domain compared to curcumin, suggesting potential competitive inhibition of IDOL's binding to LDLR. Curtn decreased liver cholesterol in Wistar rats and elevated LDLR expression. During in vitro experiments, Curtn significantly enhanced the effects of IDOL overexpression in HepG2 cells, leading to increased LDL-C uptake and elevated expression of LDL receptors. CONCLUSION Curtn modulates the IDOL/LDLR pathway, enhancing LDL cholesterol uptake in hepatocytes. Combined with its PCSK9 influence, Curtn emerges as a potential hyperlipidemia therapy.

Abstract
The pterygoid implant is a feasible alternative for posterior dental rehabilitation without grafting; however, the ideal pterygoid implant placement continues to be debated. The aim of this study was to identify effective landmarks and establish valid guidelines to determine the ideal pterygoid implant placement. Cone beam computed tomography (CBCT) data of 100 severely atrophied maxillae requiring implant rehabilitation, obtained between January 2015 and December 2018, were included. The CBCT data were obtained in DICOM format from the radiographic database and imported into Nobel Clinician software (Nobel Biocare) for radiographic analysis. Virtual pterygoid implant placement was successful in 67 maxillae: a 13-mm virtual implant in four maxillae (6.0%), 15-mm in 52 maxillae (77.6%), and 18-mm in 11 maxillae (16.4%). For the virtual pterygoid implant, the mean implant angulation± standard deviation in the anteroposterior axis (sagittal view) was 45.08 ± 2.56° relative to the Frankfort plane. In the buccopalatal axis (coronal view), the mean implant angulation was 64.30 ± 4.99° relative to the Frankfort plane and the mean value for the shortest linear distance between the palatine canal and apical tip of the virtual implant was 3.91 ± 0.62 mm. A 15-mm pterygoid implant placed at 45° in the anteroposterior axis and 60° in the buccopalatal axis (relative to the Frankfort plane), is generally recommended in this Chinese patient population.

Abstract
At present, mandibular defect repair and reconstruction is not only a simple sense of mandibular continuity restoration, but also a restoration of the physiologically positional relationship and movement balance of the upper and lower jaws. Eventually, the implantation of osseointegrated dental implants and implant-supported dental restoration should be accomplished to complete the reconstruction of the functional mandible. The technique can integrate multiple procedures such as fibular bone grafting, simultaneous dental implants and traction osteogenesis, and the perfect integration with digital technology can significantly improve the accuracy of digital dental implant traction technique. This paper will summarize and conclude the key points of the application of digital dental implant traction technique in mandibular defect reconstruction, in order to provide new ideas for the development of digital technique.

Abstract
There is limited information is known about the composition difference of the gut microbiota in patients with constipation and healthy controls. Here, the faecal 16S rRNA fastq sequence data of microbiota from the publicly available American Gut Project (AGP) were analysed. The tendency score matching (PSM) method was used to match in a 1:1 manner to control for confounding factors age, gender, body mass index (BMI), and country. A total of 524 participants including 262 patients with constipation and 262 healthy controls were included in this analysis. The richness and evenness of the gut microbiota in the constipation group were significantly lower than those in the control group. The dominant genera in the constipation group include Escherichia_Shigella, Pseudomonas, and Citrobacter. The dominant genera in the control group include Faecalibacterium, Prevotella, Roseburia, Clostridium_XlVa, and Blautia. The abundance of three butyrate production-related pathways were significantly higher in the constipation group than in the control groups. There was no significant difference in the diversity and gut microbiota composition in patients with constipation at different ages. In conclusion, patients with constipation showed gut microbiota and butyrate metabolism dysbiosis. This dysbiosis might provide a reference for the diagnosis and clinical therapy of diseases.

Abstract
Hyperlipidemia has been demonstrated to evoke Alzheimer disease (AD) pathologies such as Amyloid-β (Aβ) deposition and synaptogenesis dysfunction in the hippocampus. Curcumin gives protection against anti-amyloid properties and synaptogenesis dysfunction. Curcumin-Nicotinate (CurTn), a new type of curcumin derivative, ameliorates cognitive impairment by rescuing autophagic flux in the CA1 hippocampus of diabetic rats. However, whether Curtn possesses an antagonistic effect on AD-related pathologies in the hippocampus induced by hyperlipidemia remains ill-defined. The present study aims to investigate whether CurTn alleviates synaptogenesis dysfunction by promoting the activation of brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB)/cAMP-response element binding protein (CREB) signaling and whether the underlying fundamental mechanism involves the elimination of Aβ deposition due to Idol/low-density lipoprotein receptor (LDLR) signaling in the hippocampus of high-fat diet (HFD)-induced hyperlipidemia rats. The results demonstrated that CurTn not only improved synaptogenesis dysfunction in the hippocampus of HFD rats, as evidenced by the increases in the expressions of synapse-related proteins postsynaptic density protein 95 (PSD-95), synapsin-1, and Glutamate receptor 1 (GluR1), but also activated BDNF/TrkB/CREB signaling, as evidenced by the elevation of the expressions of BDNF, pTrkB, and CREB. Moreover, CurTn modulated the Idol/LDLR pathway in the hippocampus of HFD rats, as evidenced by the decreased expression of Idol and the increased expression of LDLR. Furthermore, CurTn eliminated the deposition of Aβ, as evidenced by the reduction in the content of Aβ40 and Aβ42. These results reveal that CurTn may attenuate synaptogenesis dysfunction by activating BDNF/TrkB/CREB signaling, as the possible result of the modulation of Idol/LDLR signaling to eliminate Aβ deposition in the hippocampus of HFD rats.

Abstract
Objective: To establish a high glucose senescent model of human dermal fibroblasts (HDFs), and to investigate the effects of exosomes derived from human decidua mesenchymal stem cells (dMSCs) on the proliferation, migration, and apoptosis of senescent HDFs and possible mechanism. Methods: The experimental research method was used. From January to March 2021, discarded foreskin tissue was collected for isolation and culture of primary HDFs from 4 male phimosis patients (aged 18-22 years) admitted for circumcision in the Fourth Medical Center of the PLA General Hospital. The 6th passage of HDFs were taken and divided into low glucose group and high glucose group according to the random number table, and subsequently cultured in low-glucose complete medium and high-glucose complete medium, respectively, with medium changed every 72 h without subculturing. After 10 days of culture, the cells were taken and measured for cellular senescence using the β-galactosidase kit at 24 h after seeding; the expression of senescence-related proteins p16 and p53 was assessed by Western blotting at 48 h after seeding; cell proliferation was detected at 24, 48, and 72 h after seeding using the cell counting kit 8 (CCK-8) method; the cell proliferation was evaluated by 5-ethynyl-2'-deoxyuridine (EdU) staining method, cell cycle and apoptosis were measured by flow cytometry after 48 h of seeding; Transwell experiment was used for the calculation of cell migration rate at 24 h after seeding. The human dMSCs were taken and cultured for 48-72 h from which the exosomes were extracted by differential high speed centrifugal method. The morphology of dMSC exosomes was observed by transmission electron microscopy, the particle size distribution of dMSC exosomes was measured by nanoparticle tracking analysis, and the expression of dMSC-exosomes marker proteins CD9 and tumor susceptibility gene101 (TSG101) were detected by Western blotting. The dMSC exosomes and high-glucose complete medium-induced senescent HDFs were co-cultured for 24 hours, then PKH67 kit was used to detect the uptake of exosomes by HDFs. High-glucose complete medium-induced senescent HDFs were taken and divided into high glucose alone group, high glucose+low concentration of exosomes group, and high glucose+high concentration of exosomes group according to the same method above. The high-glucose complete medium with equal volume of phosphate buffered saline, dMSC exosomes with final concentration of 50 μg/mL, and dMSC exosomes with final concentration of 100 μg/mL were added to the corresponding groups for conventional cell culture, respectively. After grouped, the cell proliferation, cell cycle and apoptosis as well as cell migration were detected by CCK-8 method and EdU staining method, flow cytometry, and Transwell experiment at the corresponding time points as before, respectively. Based on the previous results, high-glucose complete medium-induced senescent HDFs were taken and divided into high glucose alone group and high glucose+high concentration of exosomes group for the same treatment. After being grouped and cultured for 48 h, real-time fluorescent quantitative polymerase chain reaction was used to evaluate the mRNA expression of senescent-related microRNA (miR)-145-5p, miR-498, miR-503-5p, calcium/calmodulin dependent protein kinase 1D (CAMK1D), phosphates and tensin homologue deleted on chromosome ten (PTEN) gene, and Cyclin D1 in high glucose alone group and high glucose+high concentration of exosomes group. Data were statistically analyzed with analysis of variance for factorial design, one-way analysis of variance, least significant difference t test, and independent sample t test. Results: At 24 h after seeding, the rate of β-galactosidase-positive staining of HDF in high glucose group was (38.4±4.2)%, which was significantly higher than (16.5±2.2)% of low glucose group (t=4.65, P<0.01). At 48 h after seeding, the expression levels of senescence-related proteins p16 and p53 both were significantly higher in HDFs of high glucose group than those in low glucose group (with t values of 11.85 and 3.02, respectively, P<0.05 or P<0.01). At 0, 24, 48, and 72 h after seeding, the cell proliferation viability of HDFs in high glucose group was all significantly lower than in low glucose group (with t values of 4.13, 9.90, and 15.12, respectively, P<0.01). At 48 h after seeding, the rate of EdU-positive staining of HDFs in high glucose group was obviously lower than that of low glucose group (t=3.83, P<0.05). At 48 h after seeding, the percentage of G2/M+S subpopulations in three subpopulations (G0/G1, S, and G2/M) of HDF cycle was significantly lower in high glucose group than that in low glucose group (t=8.74, P<0.01). At 24 h after seeding, the number of HDFs migrated through the filter membrane to the lower chamber was 37±6 in high glucose group, which was significantly less than 74±7 in low glucose group (t=8.42, P<0.01). At 48 h after seeding, the HDF apoptosis rate was significantly higher in high glucose group than in low glucose group (t=8.48, P<0.01). The dMSC exosomes were cup-shaped or round vesicles with well-defined edges and uniform size distribution. The size of dMSC exosomes was basically in the range of 80-200 nm. Exosomal markers including CD9 and TSG101 were positively presented on the dMSC exosomes. After being co-cultured for 24 hours, the dMSC exosomes were taken up intracellularly by HDFs and mainly distributed around the nucleus of HDFs. After being grouped and cultured for 24, 48, and 72 h, the HDF proliferation viabilities in high glucose+low concentration of exosomes group and high glucose+high concentration of exosomes group were both significantly higher than in high glucose alone group (with t values of 6.36, 6.10, 7.76, 8.92, 12.17, and 10.74, respectively, P<0.01), the HDF proliferation viability in high glucose+high concentration of exosomes group was significantly higher than in high glucose+low concentration of exosomes group (with t values of 7.92, 4.82, and 4.72, respectively, P<0.01). After being grouped and cultured for 48 h, the percentages of EdU-positive HDFs in high glucose+low concentration of exosomes group and high glucose+high concentration of exosomes group were both significantly higher than in high glucose alone group (with t values of 5.32 and 9.88, respectively, P<0.01), the percentage of EdU-positive HDFs in high glucose+high concentration of exosomes group was notably higher than in high glucose+low concentration of exosomes group (t=5.27, P<0.01). After being grouped and cultured for 48 h, the proportion of G0/G1 subpopulation in both high glucose+low concentration of exosomes group and high glucose+high concentration of exosomes group was distinctly lower (with t values of 3.81 and 4.31, respectively, P<0.05), while the proportion of G2/M+S subpopulation was markedly higher (with t values of 3.81, 4.31, respectively, P<0.05) than in high glucose alone group. After being grouped and cultured for 24 h, the number of HDFs migrated through the filter membrane in both high glucose+low concentration of exosomes group and high glucose+high concentration of exosomes group was significantly higher than in high glucose alone group (with t values of 10.14 and 13.39, respectively, P<0.01), the number of HDFs migrated through the filter membrane in high glucose+high concentration of exosomes group was significantly increased than in high glucose+low concentration of exosomes group (t=6.27, P<0.01). After being grouped and cultured for 48 h, the HDF apoptosis rates in high glucose+low concentration of exosomes group and high glucose+high concentration of exosomes group were both significantly lower than in high glucose alone group (with t values of 3.72 and 5.53, respectively, P<0.05 or P<0.01). After being grouped and cultured for 48 h, compared with those in high glucose alone group, the mRNA expression levels of miR-145-5p and miR-498 were both obviously higher (with t values of 13.03 and 8.90, respectively, P<0.01), while the mRNA expression level of miR-503-5p was significantly lower (t=3.85, P<0.05) in high glucose+high concentration of exosomes group. After being grouped and cultured for 48 h, compared with those in high glucose alone group, the mRNA expression levels of CAMK1D and PTEN gene were both significantly lower (with t values of 8.83 and 5.97, respectively, P<0.01), while the mRNA expression level of Cyclin D1 was significantly higher in high glucose+high concentration of exosomes group (t=4.03, P<0.05). Conclusions: The dMSC exosomes are capable of improving cell proliferation and migration, and inhibiting cell apoptosis of high-glucose senescent HDFs. This may be related to the mechanism by which the increased expressions of intracellular miR-145-5p and miR-498 inhibit the expression of CAMK1D and PTEN gene, and the decreased expression of miR-503-5p promote the expression of Cyclin D1.

INTRODUCTION The frequency of celiac disease autoantibody (CDAb) positivity in type 1 diabetes (T1D) has increased due to unclear mechanisms, including autoimmune injury. Circular ribonucleic acids (circRNAs) participate in autoimmune diseases, but the roles of circRNAs in T1D with CDAbs are currently unknown. This study aimed to determine the frequency of CDAbs in Chinese children with T1D and describe the relationship between CDAbs and circRNAs. MATERIALS AND METHODS Eighty patients diagnosed with T1D were screened for CDAbs and CD-predisposing genes, and circRNAs in peripheral blood mononuclear cells (PBMCs) were collected from 47 patients. The Gene Expression Omnibus (GEO) database was searched for candidate circRNAs in related studies on T1D PBMCs. Data on clinical characteristics (i.e., blood glucose control, residual islet function, and daily insulin dosage) and immunophenotypes (i.e., islet autoantibodies and immune cell subsets) were collected. RESULTS In total, 35.0% of patients were positive for CDAbs. CD-predisposing genes accounted for 52.5% of the genes, and no significant difference in frequency was found between the CDAb-positive (CDAb+) and CDAb-negative (CDAb-) groups. In addition, among the differentially expressed circRNAs from the GEO database, five highly conserved circRNAs homologous to humans and mice were screened, and only the expression of hsa_circ_0004564 in the CDAb+ group significantly decreased (CDAb+ vs. CDAb-:1.72 ± 1.92 vs. 11.12 ± 8.59, p = 6.0 × 10-6), while the expression of hsa_circ_0004564 was upregulated in the general T1D population. Moreover, its parental gene RAPH1 was significantly upregulated (CDAb+ vs. CDAb-:1.26 ± 0.99 vs. 0.61 ± 0.46, p = 0.011). Importantly, the positive correlation between hsa_circ_0004564 and CD3+ cells was validated in children with T1D after adjustments for CDAbs (p = 0.029), while there were no correlations between hsa_circ_0004564 and clinical characteristics or other immune cell subsets (i.e., CD4+ T cells, CD8+ T cells, and natural killer cells). CONCLUSION This study highlights the importance of screening for CD in Chinese children with T1D, considering the high prevalence of CDAb positivity and CD-predisposing genes. The profile of candidate circRNAs in children with T1D with CDAbs was different from that in previous reports on general T1D patients from the GEO database. Moreover, hsa_circ_0004564 and its parental gene RAPH1 may be new targets for studying immune mechanisms in children with T1D and CD.

Abstract
Objective: To explore the safety and efficacy of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in complex high-risk and indicated patients (CHIP). Methods: This is a single-center retrospective study. Patients who underwent percutaneous coronary intervention (PCI) supported by VA-ECMO in the Second Hospital of Jilin University from June 2018 to January 2020 were enrolled. General clinical data, laboratory examination results, PCI and ECMO process, postoperative complications and prognosis were collected through the electronic medical record system. The endpoint of the study was major adverse cardiovascular events (MACE), defined as complex events including cardiac death, recurrent myocardial infarction, heart failure and malignant arrhythmia. All patients were followed up for 12 months after discharge. Kaplan-Meier method was used for survival analysis. Results: A total of 31 patients, aged (64.6±10.1) years, including 19 males were included. All patients were treated with VA-ECMO before PCI. The ProGlide vascular suture device was embedded by local anesthesia to quickly establish circulation. There were 9 (29.0%) patients with ST-segment elevation myocardial infarction, 10 (32.3%) patients with non-ST-segment elevation myocardial infarction and 12 (38.7%) patients with unstable angina. The number of stents implanted during the operation were 2.8±1.8. The VA-ECMO weaning time was 24.0 (2.0, 88.5) hours. Compared with the results of pre-operation, the patient's postoperative left ventricular ejection fraction was significantly improved (49% (42%, 55%) vs. 43% (35%, 52%), P<0.01], hemoglobin and platelet count levels decreased, the level of creatinine and urea nitrogen was increased (P<0.05). Within 24 hours after operation, hemoglobin decreased>20 g/L was observed in 18 cases (58.1%), puncture site bleeding was found in 2 cases (6.5%), pseudoaneurysm occurred in 1 case (3.2%) and postoperative cerebral infarction occurred in 1 case (3.2%). There were no deaths during the operation, 2 patients died during hospitalization. All discharged patients were followed up for 12 months. The incidence of MACE was 13.8% (4/29). During the follow-up period, 2 patients died. One patient was hospitalized with recurrent myocardial infarction and one patient with heart failure. Survival analysis was performed 12 months after intervention and the cumulative survival rate was 80.0%. Conclusion: The application of VA-ECMO in CHIP interventional therapy is safe, effective and feasible.

Abstract
We report observations of gamma-ray emissions with energies in the 100-TeV energy region from the Cygnus region in our Galaxy. Two sources are significantly detected in the directions of the Cygnus OB1 and OB2 associations. Based on their positional coincidences, we associate one with a pulsar PSR J2032+4127 and the other mainly with a pulsar wind nebula PWN G75.2+0.1, with the pulsar moving away from its original birthplace situated around the centroid of the observed gamma-ray emission. This work would stimulate further studies of particle acceleration mechanisms at these gamma-ray sources.

Abstract
Oxidative stress induces the formation of oxidized low-density lipoprotein (ox-LDL), which accelerates the development of atherosclerosis and the rupture of atherosclerotic plaques by promoting lipid accumulation and inhibiting autophagy in vascular cells. Lipophagy is known to be involved in maintaining the balance of neutral lipid metabolism; however, the phenomenon of lipophagy deficiency in ox-LDL-treated endothelial cells (ECs) remains to be elucidated. It has been demonstrated that lipid accumulation caused by ox-LDL inhibits autophagy, which promotes apoptosis in ECs. The aim of the present study was to investigate the association between decreased autophagy and lipid accumulation in ECs treated with ox-LDL. Electron microscopy demonstrated that the formation of autolipophagosomes was decreased in ox-LDL-treated human umbilical vein ECs compared with that in the LDL-treated group and was accompanied by a decrease in the autophagy-associated proteins via western blotting analysis. Using laser focal colocalization detection, decreased lipid processing was observed in the lysosomes of ox-LDL-treated ECs, which indicated that lipophagy may be attenuated and subsequently result in lipid accumulation in ox-LDL-treated ECs.

Abstract
Objective To observe the impact of quercetin and isoquercitrin on gluconeogenesis in hepatocytes. Methods Mouse primary hepatocytes were cultured with lactic acid and pyruvic acid. After treatment with quercetin and isoquercitrin for 24 hours, the glucose concentration in the culture supernatant was determined. RT-PCR was used to detect the mRNAs of PEPCK, G6Pase, LKB1, and AMPKα. Protein levels of LKB1, AMPKα, and Thr172 phosphorylation were evaluated by Western blot. Results The glucose concentration in the gluconeogenesis group (GN) was significantly higher than in the control group (C), but the glucose concentrations in the high level quercetin(group 80Q) and high level isoquercitrin (group 80I) were significantly lower than in the group GN, P<0.01. In the group 80Q, and group 80I, the mRNA levels of PEPCK and LKB1were significantly lower than in the group GN (P<0.01), and the G6Pase mRNA were significantly lower than in the group GN (P<0.05). The protein levels of LKB1 and the phosphorylation of AMPKα Thr172 in the group 80Q, group 40I, and group 80I were higher than in the group GN. The effects of quercetin and isoquercitrin on LKB1 and AMPKα were similar to those of metformin. Conclusions Quercetin and isoquercitrin inhibit gluconeogenesis in hepatocytes, which may be related to the LKB1 upregulation and phosphorylation of AMPKα.

Abstract
Human health is threatened by obesity which causes the increasing incidence of various diseases, especially stroke. Ischemic stroke (IS) is mostly caused by the rupture of arterial plaque, whose instability is positively associated with matrix metalloproteinases (MMPs) that degrades extracellular matrix components. Studies have shown that matrix metalloproteinase-12 (MMP-12) may be involved in the pathogenesis of IS. Because of the higher incidence of stroke in obese patients than that in normal weight people, it is urgent for obesity to forecast stroke early. Considering high levels MMP-12 in obesity, we put forward that MMP-12 may be a potential biomarker for IS in obese patients.

Abstract
The SREBP2/LDLR pathway is sensitive to cholesterol content in the endoplasmic reticulum (ER), while membrane low-density lipoprotein receptor (LDLR) is influenced by sterol response element binding protein 2 (SREBP2), pro-protein convertase subtilisin/kexin type 9 (PCSK9) and inducible degrader of LDLR (IDOL). LDL-C, one of the risk factors in cardiovascular disease, is cleared through endocytosis recycling of LDLR. Therefore, we propose that a balance between LDLR endocytosis recycling and PCSK9-mediated and IDOL-mediated lysosomal LDLR degradation is responsible for cholesterol homeostasis in the ER. For statins that decrease serum LDL-C levels via cholesterol synthesis inhibition, the mechanism by which the statins increase the membrane LDLR may be regulated by cholesterol homeostasis in the ER.

Abstract
OBJECTIVE To understand the strategy of schistosomiasis elimination and its effects in Jinhu County, Jiangsu Province. METHODS The data of schistosomiasis control in Jinhu County at different stages from 1970 to 2017 were collected and analyzed. RESULTS From 1970 to 2017, there were three stages of schistosomiasis control, including transmission control, transmission interruption, and monitoring and elimination stages in Jinhu County. The main measures included Oncomelania hupensis snail control, infectious source control, and health education. A total of area of 290 691.78 hm2 was detected in Jinhu County, and the area with snails was 3 420.98 hm2. There were 8 729.37 hm2 area with snails was controlled. Since 2014, no O. hupensis snails were found. A total of 525 377 person-times were examined for schistosomiasis, with 2 815 schistosomiasis patients identified, and 2 844 person-times were treated by chemotherapy. In addition, 977 cases received the expand chemotherapy. Since 1990, no local schistosome-infected persons were found. In 2017, the awareness rate of schistosomiasis control knowledge and the correct rate of health behavior were increased by 54.59% and 14.23% respectively compared with those in 1992. CONCLUSIONS The comprehensive schistosomiasis control measures implemented in Jinhu County at different periods have achieved remarkable outputs and accelerated the schistosomiasis elimination process. However, the precise control measures should be implemented in the future to consolidate the prevention and control achievements.

Abstract
Objective: To investigate the ultrastructural features of muscle in patients with mitochondrial encephalomyopathy for its diagnosis and differential diagnosis. Methods: The clinical data of 27 mitochondrial encephalomyopathy patients who underwent left or right biceps brachii muscle biopsy at Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University from July 2006 to August 2017 were analyzed retrospectively. The muscle biopsy specimens were examined underlight microscope and transmission electron microscope. Results: There were 27 patients (17 males, 10 females) with an age range of 12 to 62 years (mean 29 years). The age of onset ranged from 3 to 38 years. The course of disease ranged from 1 month to 24 years. Twenty-two cases presented with lactic acidosis and stroke-like episodes (MELAS) syndrome, four with myoclonic epilepsy with ragged red fibers (MERRF) syndrome, and one with chronic progressive paralysis of extraocular muscle (CPEO) syndrome. Skeletal muscle biopsy showed abundant ragged red fibers and strongly SDH-reactive vessel. Genetic studies showed 17 of 22 cases of MELAS syndrome had A3243G mutation, and the other 5 cases had no abnormality. A8344G mutation was found in 3 of 4 cases of MERRF syndrome. No single or multiple mtDNA mutations were found in the single case of CPEO. Transmission electron microscopy of all 27 cases showed diffuse proliferation of mitochondria between the myofibrils and beneath the sarcolemma, with increased spacing between muscle cells. Seven cases showed numerous glycogen and four showed subsarcolemmal lipid droplets, 13 cases showed unusual mitochondrial morphology, including mitochondrial electron-dense substances and paracrystal line inclusions ("parking lot" change)in eight cases. Conclusions: Transmission electron microscopy shows significant differences in ultrastructural pathological changes among different patients with mitochondrial encephalomyopathy. Some patients with mild clinical symptoms have increased mitochondrial number, increased metabolism of glycogen and lipid droplets, while others with severe clinical symptoms have abnormal mitochondrial morphology. Typical crystalloid inclusions are found in mitochondria, which are of great value in the diagnosis of this disease.

Abstract
Type 2 diabetes mellitus (T2DM) is a chronic degenerative endocrine and metabolic disease with high mortality and morbidity, yet lacks effective therapeutics. We recently generated a novel fusion peptide INSR-IgG4Fc, Yiminsu (YMS), to facilitate the high-affinity binding and transportation of insulin. Thus, the aim of the present study was to determine whether the novel recombinant peptide, YMS, could contribute to restoring insulin sensitivity and glycaemic control in insulin resistance models and revealing its underlying mechanism. Palmitic acid (PA)-treated LO2 cells and high fat diet (HFD)-fed mice were treated with YMS. Therapeutic effects of YMS were measured using Western blotting, ELISA, qPCR, Histology and transmission electron microscopy. We observed that YMS treatment effectively improved insulin signaling in PA-treated LO2 cells and HFD-fed mice. Notably, YMS could significantly reduce serum levels of glucose, triglycerides, fatty acids and cholesterol without affecting the serum insulin levels. Moreover, our data demonstrated that YMS could restore glucose and lipid homeostasis via facilitating insulin transportation and reactivating PI3K/Akt signaling in both PA-treated cells and liver, gastrocnemius and brown fat of HFD-fed mice. Additionally, we noticed that the therapeutic effects of YMS was similar as rosiglitazone, a well-recognized insulin sensitizer. Our findings suggested that YMS is a potentially candidate for pharmacotherapy for metabolic disorders associated with insulin resistance, particularly in T2DM.

Abstract
The surgical approach to the resection of oral tongue cancers can involve transoral resection (TOR) or a temporary mandibulotomy access (TMA). There are no relevant guidelines, and the oncological safety of TOR needs consideration. The objective of this study was to investigate TMA and TOR in pT2 oral tongue cancer surgery with regard to cancer outcomes. Demographic, surgical, and histology data from primary pT2 tongue cancers were recorded and evaluated through multivariate Cox regression for local recurrence (LR), disease-free survival (DFS), and overall survival (OS). A total of 166 patients with pT2 primary oral tongue cancer fulfilled the inclusion criteria; TOR was used in 95 patients and TMA in 71 patients. The minimum follow-up was 29 months. Group comparisons showed a significantly higher frequency of perineural spread (P=0.013) in the TMA group; a higher frequency of involved margins on initial resection was seen in TOR patients (P=0.010). Adjuvant postoperative radiotherapy was preferred in the TMA group, in line with the high pN positive status. Multivariate Cox regression showed significantly higher LR and lower DFS in the TOR group despite stratification of the major prognostic factors. The 5-year survival rate was reduced to 82.2% in the TOR group, while it remained constant at 93.0% in the TMA group. TMA provided superior local control and DFS compared to TOR in pT2 tongue cancers.

Abstract
A pump-probe scheme for monitoring the electron dynamics of the excited state has been investigated by numerically solving the two-state time-dependent Schrödinger equation based on the non-Born-Oppenheimer approximation. By adjusting the delay time between a mid-infrared probe pulse and an ultra violet pump pulse, an obvious minimum can be seen in the higher-order harmonic region. With electron probability density distribution, ionization rate and classical simulation, the minimum can be ascribed to the electron localization around one nucleus at larger delay time and represents the electron dynamics of the excited state at the time of ionization. Moreover, the position of the minimum is much more sensitive to the nuclear motion.

Abstract
The advance of clinical diagnosis and treatment in oral and maxillofacial-head and neck tumors has been through the process of specialization and multidisciplinary cooperation. In most cases, a single discipline cannot meet the requirements of diagnosis and treatment, which needs the cooperation of oral and maxillofacial surgery, otolaryngology and oncology approach and therapeutic method such as surgery, radiotherapy and chemotherapy. Holistic integrative medicine aims at integrating the most effective clinical practice experience and patients' individual situation and prognosis, establishing new medical mode conforming to the modern concept and fulfilling the medical system adapting to the specific characteristics of the diseases.

Abstract
Neuropilin 2 (Nrp2) plays an important role in regulating lymphangiogenesis. Nrp2 expression in early tongue cancer was investigated to predict lymph node metastasis and the long-term prognosis. The relationships between clinicopathological variables of cT1-T2N0 tongue squamous cell carcinoma (SCC) and overexpression of Nrp2, vascular endothelial growth factor C (VEGFC), vascular endothelial growth factor receptor 3 (VEGFR3), and semaphorin 3F (Sema3F) were analyzed. Expression levels were compared using oral SCC cell lines. The Nrp2 gene was silenced to determine the impact of Nrp2. Cytoplasmic Nrp2 overexpression predicted regional metastasis with sensitivity and specificity of 90.3% and 42.1%, respectively. Cytoplasmic Nrp2 overexpression (P<0.001) and VEGFC overexpression (P=0.006) were significantly related to regional metastasis (Student t-test). However, only cytoplasmic Nrp2 overexpression was an independent prognostic factor for both disease-free survival (DFS; P=0.008) and overall survival (OS; P=0.016) (Cox regression); the risk of recurrence was 12-times higher (P=0.015) and risk of mortality was 8-times higher (P=0.016). Co-localization of Nrp2 and VEGFC was greater within the cytoplasm of aggressive cell lines (HN12 and RCa-T). Nrp2 plays a role in tumourigenesis; VEGFC supplementation cannot rescue the biological function of Nrp2 in Nrp2-depleted cell lines. Cytoplasmic Nrp2 overexpression is associated with decreased OS and DFS. Cytoplasmic Nrp2 overexpression may be a reliable diagnostic and prognostic marker for early tongue SCC.

Abstract
BACKGROUND/PURPOSE Autofluorescence has become an important factor associated with diagnosis and treatment of many diseases. METHODS Full thickness skin grafts and scar biopsies were obtained from five volunteers. The normal skin or scar tissue paraffin-wax sections were stained with HE and the autofluorescence of collagen fibres was viewed under fluorescence microscopy. RESULTS In normal skin, the autofluorescence was showed in dermis, specifically in collagen fibres. There was very weak autofluorescence in epidermis. The spectrum was excited at 488 nm and the peak value of autofluorescence was significantly different between reticular layer (169.24±9.18) and papillar layer of dermis (103.91±15.23). In scar tissue, the autofluorescence was showed in collagen fibres and the peak value was 176.71±20.69. The structure of collagen fibres in normal skin or scar tissue was different in loose degree, thickness, boundle size, and morphology by their autofluorescence. CONCLUSION The different peak value of autofluorescence between scar and normal skin may due to the different density of collagen fibtes in them. This study may provide us a simple and effective assessment indicator and method for diagnosis and treatment of scar.

Abstract
The molecular multiple rescattering processes have been theoretically investigated via solving the time-dependent Schrödinger equation. Not only has the physical model been established, but also the related rescatterings originating from recombination with parent nucleus and with neighboring nucleus have been distinguished. Moreover, it has shown that the rescatterings originating from recombination with parent nucleus are similar with those atomic rescatterings, while those rescatterings from recombination with neighboring nucleus both before and after reversing the direction of the laser field are more sensitive to the internuclear distance. With time-frequency distribution and classical electron dynamics, the underlying mechanisms are revealed.

Abstract
Familial gigantiform cementoma is a rare benign fibrocemento-osseous lesion of the jaws that can cause severe facial deformity. It has an autosomal dominant mode of inheritance, but varies in its phenotype. It is more common in white, African, and East-Asian patients. Here we report what is to our knowledge the first distinctive Chinese family with familial gigantiform cementoma involving 4 generations and 13 patients, and which suggests that the tumour presents with 3 distinctive growth phrases.

Abstract
The purpose of this paper is to present an innovative method for tongue reconstruction after cancer ablation using the medial sural artery perforator flap with the aid of preoperative computed tomography angiography (CTA) mapping. We describe the case of one patient treated with this technique and illustrate the anatomy of perforator vessels and the surgical techniques used in flap harvest. CTA was applied preoperatively to assess the number and location of medial sural artery perforators. The result obtained was both aesthetically and functionally satisfactory. The flap presented has the advantage of less donor site morbidity, and being thin, it is a suitable option for tongue reconstruction including that of a hemiglossectomy defect. CTA is an effective means of improving the safety of flap harvest.

Abstract
BACKGROUND Randomized trials have not shown major survival benefits when induction chemotherapy plus standard therapy is compared with standard therapy alone in patients with oral squamous cell carcinoma (OSCC). Induction chemotherapy is likely to be effective for biologically distinct subgroups and biomarker development may lead to identification of patients whose tumors are likely to respond to a particular treatment. PATIENTS AND METHODS We evaluated immunohistochemical staining for GDF15 in pretreatment biopsy specimens of 230 of 256 OSCC patients who were treated in a prospective, randomized, phase III trial on induction chemotherapy including docetaxel, cisplatin and 5-fluorouracil (TPF). Relationship between GDF15 intervention and cell proliferation, migration, invasion, colony formation and tumorigenicity was analyzed using in vitro and in vivo OSCC models. RESULTS Low GDF15 expression predicted a better survival in OSCC patients, especially overall survival [P = 0.049, hazard ratio (HR) = 0.597] and distant metastasis-free survival (DMFS; P = 0.031, HR = 0.562). cN+ patients with low GDF15 expression benefitted from induction TPF in overall survival (P = 0.039, HR = 0.247) and DMFS (P = 0.039, HR = 0.247), cN- patients with high GDF15 expression benefitted from induction TPF in overall survival (P = 0.019, HR = 0.231), disease-free survival (P = 0.011, HR = 0.281), locoregional recurrence-free survival (P = 0.035, HR = 0.347) and DMFS (P = 0.009, HR = 0.197). Decreased GDF15 expression in OSCC lines significantly inhibited cell proliferation, migration, invasion, colony formation and tumorigenesis through increased phosphorylation of AKT and ERK1/2 (P < 0.05). Likewise, overexpression of GDF15 significantly promoted cell proliferation, migration, invasion and colony formation through decreased phosphorylation of AKT and ERK1/2 (P < 0.05). CONCLUSIONS GDF15 expression can be used as a prognostic biomarker for OSCC, and as a predictive biomarker for benefitting from TPF induction chemotherapy. GDF15 promotes tumorigenesis and progression through phosphorylation of AKT and ERK1/2 in OSCC. The clinical trial in this study was registered with www.ClinicalTrials.gov (NCT01542931).

Abstract
Laryngeal carcinoma is a common tumor of the head and neck region. This study aimed to examine the outcomes of laryngectomy in elderly patients with laryngeal carcinoma. One-hundred twenty-two patients (male, 117; female, 5) aged 60 years or older (range, 60-94 years) who underwent laryngectomy between 1996 and 2010 were included. All patients were diagnosed with squamous cell carcinoma of the larynx, and 95 patients (77.9%) had additional concurrent diseases. Tumors were staged according to the TNM categories of the American Joint Committee on Cancer 2002 criteria; there were 16 stage-I, 24 stage-II, 52 stage-III, and 30 stage-IV cases. With regard to treatment modalities, 10 patients underwent transoral laser laryngectomy, 25 underwent partial laryngectomy, and 87 underwent total laryngectomy. When necessary, neck dissection was performed according to the Dalian criteria set in 2004 (a Chinese standard). Of the 122 cases, there were 114 cases of grade I (93.4%), 5 cases of grade II, and 3 cases of grade III (pharyngeal fistula in 2 cases recovered after 2 weeks of care) wound healing. No significant differences were observed in the occurrence or severity of comorbidities. The 1-, 3-, and 5-year actuarial survival rates were 97.5% (119/122), 84.4% (92/109), and 68.4% (67/98), respectively. Age alone should not be used to determine treatment options for elderly patients with squamous cell carcinoma. Presuming that careful pre-treatment evaluations are performed, laryngectomy is a key method for elderly patients with laryngeal carcinoma.

Abstract
Profilins are small proteins essential for many normal cellular dynamics and constitute one of the crucial components of actin-based cellular motility. Several recent studies have implicated a role for the profilin (PFN) family in cancer pathogenesis and progression. However, their expression and promising functions are largely unknown in oral squamous cell carcinoma (OSCC). In this study, we analyzed the correlation between PFN1 and PFN2 expression in vitro and in vivo. The protein expression levels were roughly compared between cell lines (HIOEC, HB96) with the employment of mass spectrometry. PFN2 was singled out as one of the significantly down-regulated genes in the cancerous HB96 cells. The expression levels of PFN1 and PFN2 in vitro were validated by RT-PCR, real-time PCR and Western blotting. Laser scanning confocal microscopy was used for the first time to assess the localization of PFN2 expression. In subsequent experiments, we observed the relationship between PFN2 expression levels and the proliferation of transfected HB96 cancer cells. VASP, N-WASP and P27 expression was also examined in the PFN2-transfected or non-transfected HB96 cells. In vivo, antigen expression was determined by immunohistochemical analyses in 88 paired tissue specimens. Decreased protein expression was confirmed in cancerous tissues from 88 OSCC patients compared with paracancerous normal mucous epithelia. Tumors with weak PFN2 expression were associated with a significantly worse prognosis than strongly expressed tumours (P<0.001). Other statistical analyses were performed to assess the differences in expression and their clinical and pathological significance. In conclusion, PFN2 can be utilized as both a potential suppressor marker and a prognostic protein for OSCC. The function of PFN2 may be to regulate the N-WASP/Arp2/3 signaling pathway.

Abstract
AIMS To investigate the trend in the prevalence of gestational diabetes mellitus during 1999-2008 in women living in urban Tianjin, China. METHODS A universal screening for gestational diabetes mellitus has become an integral part of the antenatal care in Tianjin, China from 1998. A total of 105,473 pregnant women living in the six urban districts of Tianjin, China, participated in the gestational diabetes mellitus screening programme between December 1998 and December 2008. The screening test consisted of a 50-g 1-h glucose test. Women who had a glucose reading ≥7.8 mmol/l at the initial screening were invited to undergo the standard 2-h oral glucose tolerance test with a 75-g glucose load. Gestational diabetes mellitus was confirmed using the World Health Organization's diagnostic criteria. RESULTS The adjusted prevalence of gestational diabetes mellitus increased by 2.8 times during 1999-2008, from 2.4 to 6.8% (P<0.0001 for linear trend). In 2008, the age-specific prevalence of gestational diabetes mellitus was the highest among women aged 30-34 years (11.3%) and lowest among women aged 25 and under (1.2%). In women aged 35 years and more, the prevalence was 5.3%. CONCLUSIONS The prevalence of gestational diabetes mellitus has markedly been increasing in a universally screened urban Chinese female population and has become an important public health problem in China.

Abstract
In August of 2008, a disease of chrysanthemum (Dendranthema morifolium (Ramat.) Tzvel) caused losses of 70 to 80% in one of the largest chrysanthemum gardens in Yangling, Shanxi Province, China. Chrysanthemum plants in nearby areas also were affected to various degrees. Symptoms included flattened stems, shortening of internodes, yellowing of leaf margins, root death, and dwarfing of plants. Affected plants eventually collapsed. On the basis of these symptoms, a phytoplasma was suspected. Total nucleic acids were extracted from 0.5 g of phloem tissue from stems of eight symptomatic and eight asymptomatic plants by the cetyltrimethylammoniumbromide (CTAB) method (1). To amplify phytoplasma DNA, primer pairs R16mF2/R16mR1, followed by R16F2n/R16R1 (2), were used in a nested PCR. A final amplicon product (1.2 kb) was obtained from all symptomatic plants but not from asymptomatic ones. Restriction fragment length polymorphism (RFLP) analyses of R16F2n/R16R1 amplicons with MseI, AluI, HhaI, HaeIII, KpnI, RsaI, and HpaII endonucleases indicated that all symptomatic plants, but none of the asymptomatic plants, contained a phytoplasma strain of group 16SrI, subgroup B (3). A search of rDNA sequences in GenBank revealed a similarity (>99%) to aster yellow phytoplasma, 16SrI group, thereby confirming strain identity based on RFLP analysis. These results indicate the disease of chrysanthemum is associated with a phytoplasma related to the aster yellow phytoplasma group. Sequences were deposited in GenBank (Accession No. FJ543467). A vector of this phytoplasma in chrysanthemum has not been identified. References: (1) E. Angelini et al. Vitis 40:79, 2001. (2) D. E. Gundersen and I.-M. Lee. Phytopathol. Mediterr. 35:144, 1996.

Abstract
Bamboos are ecologically and economically valuable plants. Young shoots of almost all species are edible, either raw or cooked, and are major components of Asian cuisine while culms are used for furniture or handicrafts as well as fuel wood. Symptoms indicative of phytoplasma disease were observed on Sasa fortunei (van Houtte) Fiori during a survey in Yangling, Shaanxi Province, China during 2007. Symptoms included internode shortening, a mosaic pattern on leaves of diminished size, stunted growth, and death of entire plants. Total nucleic acids were extracted from leaf veins of 10 diseased plants and 6 symptomless plants with a modified cetyltrimethylammoniumbromide (CTAB) method (1). Phytoplasma infection of plants was demonstrated by a nested PCR assay employing primer pair R16mF2/R16mR1 followed by R16F2n/R16R2 (2), which generated a 16S rDNA product of approximately 1.2 kb from all symptomatic plants only. Restriction fragment length polymorphism analysis by digestion of nested PCR products with restriction enzymes AluI and MseI indicated that S. fortunei plants contained group 16SrI (aster yellows), subgroup B phytoplasmas. Sequencing and phylogenetic analysis of phytoplasma 16S rDNA from S. fortunei (GenBank Accession No. FJ501958) revealed this strain to be very similar (99.7 and 99.6%, respectively) to phytoplasmas previously associated with Henon bamboo (Phyllostachys nigra) witches'-broom (GenBank Accession No. AB242433) (4) and sasa (S. borealis) witches'-broom (GenBank Accession No. AB293421) in Korea but less so (98.6%) to bamboo (Phyllostachys spp.) witches'-broom (GenBank Accession No. AY635145) disease in China (3). To our knowledge, this is the first report of a 'Ca. Phytoplasma asteris'-related strain infecting S. fortunei in China. References: (1) E. Angelini et al. Vitis 40:79, 2001. (2) D. E.

Abstract
OBJECTIVE To study the characteristics and influencing factors on hearing impairment among elderly population in the community of Taiyuan city. METHODS 384 ageing people above 60 years old were selected from Chaoyang and Guandi community in Taiyuan city by multi-stage sampling. Data on influencing factors of hearing impairment were collected by questionnaire. 5 ml fasting blood samples were drawn to detect the level of glucose, triglyceride and cholesterin in the blood samples. All the objects were tested with binaural hearing. The level of binaural hearing threshold at 0.5 kHz, 1 kHz, 2 kHz, 3 kHz, 4 kHz, 8 kHz were measured by GVSLN-TC-GK2000 hearing-assistant evaluative apparatus. The level of 3 kHz, 4 kHz, average hearing threshold from ear with better audition was chosen as dependent variable. Socio-demographic data, environmental factors and biochemical indicator were chosen as independent variables, t test, ANOVA and accumulative logistic regression were performed to analyze the influencing factors on hearing impairment by software SPSS 13.0. RESULTS The prevalence of hearing impairment among elderly population was 90.9%. The hearing disorder was 78.6% with 1.3% of them using hearing-assistant apparatus. Results from single factor analysis showed that the average levels of 3 kHz, 4 kHz, 8 kHz hearing thresholds were significantly different among elderly with different age, sex, education background and the levels of glucose and cholesterin (P < 0.01). Results of accumulative logistics regression showed that except glucose in which was the only one included in regression model of lower median frequency group, all the others were included in regression model of frequency group. Being male, older age and with higher level of glucose and cholesterin in blood were risk factors causing hearing impairment. Higher education level seemed to be a preventive factor. CONCLUSION Hearing impairment appeared in higher prevalence among the elderly population, suggesting that proper measures should be taken. It is beneficial for abating hearing impairment to decrease the level of glucose and cholesterin in blood.

Abstract
OBJECTIVE To investigate the toll-like receptors (TLR) profile of human epidermal keratinocytes. METHODS We cultured the immortalized human epidermal keratinocyte cell line HaCaT cells and normal human epidermal keratinocytes (NHEK) and separated epidermis with dispase from foreskins. TLR 1-10 mRNA expression was detected with reverse transcription polymerase chain reaction (RT-PCR). TLR 2 and 4 protein expressions on surface of HaCaT cells and NHEK were detected using flow cytometry. RESULTS HaCaT cells, NHEK, and epidermis all expressed TLR 1-10 mRNA with different intensity. TLR 4 protein was detected on the surfaces of HaCaT cells and NHEK, while the expression of TLR 2 protein was few. CONCLUSION Human epidermal keratinocytes constitutively express all TLR 1-10 mRNA, which may enable human keratinocytes to respond to a wide range of pathogenic micro-organisms.

Abstract
Here is described a modified technique of palatomaxillary reconstruction that combines the use of a free vascularized bone graft by osteotomy, soft-tissue flap, zygomatic implant as an anchorage and two standard implants simultaneously. The patient presented with deformity in the left face after subtotal maxillectomy (Brown 2b classification). Preoperative work up was performed by a rapid prototyping model using computer-aided manufacturing technology. The purpose of this model is to provide accurate measurements of the defect. The palatomaxillary three-dimensional buttress system can be managed by orienting the bone graft vertically and horizontally. Reconstruction of the palatomaxillary defect was successfully accomplished in a single surgical procedure. Dental implant restoration achieved good osseointegration without any significant resorption. This new modification represents a significant contribution to palatomaxillary reconstruction using zygomatic implants as anchorage.

Abstract
The aim of this study was to analyse the experience at a single institution in carotid artery resection with or without reconstruction performed as part of an oncological procedure or emergency haemostasis. A total of 28 patients were included in this retrospective study; 17 underwent ligation or resection of the carotid artery, and 11 underwent reconstruction of the carotid artery. The perioperative complications and surgical outcomes were recorded and analysed. Of the 17 patients with ligation or resection of the carotid artery, 4 developed neurologic deficit within 2 weeks postoperatively. Three patients with malignant tumours died 1 month (1) and 4 months (2) postoperatively. Of the 11 patients undergoing carotid reconstruction, no major cerebral complications were noted after operation. Colour Doppler showed patent vascular graft 1 year postoperatively in nine patients. Due to the higher complication rates both in short and long term with ligation or resection of the carotid artery, resection and revascularization of the carotid artery is advocated for patients with carotid artery involvement when possible.

Abstract
Effects of fungal elicitor on cell redox status and taxol production were studied in suspension cultures of Taxus chinesis var. mairei in the late exponential stage. The results show that fungal elicitor induced oxygen burst, changes of the cell redox status, alkalinization of medium and the fluctuation of the activity of redox enzymes with a sequence. The content of protein representing the quantity of enzymes increased. The activity of SOD increased quickly after treatment by fungal elicitor and that of POD could be kept at a higher level in contrast to the control. The activity of CAT was inhibited at first and followed by an obvious increase, while the activity of PAL was promoted. The taxol yield was 5 folds of the control, reaching to 67 mg/L.

Abstract
OBJECTIVE To report our experience to embolize the AVM of jaws by direct percutaneous puncture. in conjunction with endovascular therapy. METHODS 3 cases of AVM of mandible and 3 cases of AVM of maxilla comprised this study group. The patients were embolized with fibered coils, PVA and NBCA. The coils were placed directly into the center of the intraosseous lesion. The procedure was under the guidance of DSA machine (PHILIPS V3000). RESULTS The acute arterial bleeding in 4 patients was controllable. The other two cases with oozing bleeding and a warm soft mass on the left face with a palpable pulse respectively, their symptoms and signs got improved a lot. The pericoronal oozing of blood in all patients disappeared during a 3 to 24 months follow-up and new bone formation was found in the follow-up radiography. CONCLUSION The embolization of the AVM of jaws by direct percutaneous puncture in conjunction with endovascular therapy is effective and safe, however the longer follow-up is expected.

Abstract
OBJECTIVE To investigate the relationship between the changes of salivary epidermal growth factor (sEGF) concentration and oromaxillofacial tumors so as to find out its potential clinical value. METHODS The saliva of 123 patients with oromaxillofacial tumors,inflammations and precancerous lesions were measured for EGF concentration by radioimmunoassay (RIA) with the ligand(125)I-EGF and the saliva of 40 normal adults as the control. RESULTS Compared with the control, sEGF level of malignant,benign salivary gland tumors increased obviously;the former is higher than the latter significantly. The sEGF levels of patients with squamous cell carcinoma (SCC) of mucosa,recurrence and precancerous lesion were significantly higher than that of the control. There was no significant difference among the groups,but there was a tendency to increase by degrees. Compared with the control,the increase of the sEGF level of SCC patients with lymph node metastasis was of no significance. The sEGF level of oromaxillofacial inflammation was significantly higher than that of control. CONCLUSION The sEGF levels in patients with salivary gland tumor,SCC,inflammation increased in different degrees.
