Objective:To summarize the expierence in the prostheti c treatment of serious attrition with defect of dentition in old people. Methods: Removable denture with occlusal pad was one timely prepa red for 32 people aged 58～80 years old with serious attrition and defect of de n tition. 6 of the patients had temporomandibular disturbance (TMD). The time of f ollow up visit of the patients ranged from 2.5 months to 5 years.Res ults: The masticatory function of the patients was improved obviousl y .Unilateral mastication was achieved. The symptom of articulation was all rel ieved.The occlusal relationship was not changed or occlusal vertical dimension ( OVD) was appropriately increased in the patients without TMD. The symptom of TMD did not appear after using denture in patiends with TMD.Conclu sions:During occlusal reconstruction in old people with serious attri tion and defect of dentition, the recovery of OVD and occlusal relationship is v ery important.

To explore the impact of acceleration load on the temporomandibularjoint in aviators and its clinical significance.617 aviators flying aircraft of different types without previous history of temporomandibularjoint disease were studied. Abnormal manifestations of the temporomandibularjointswere analysed. The incidence of temporomandibular joint symptoms was markedly higher in the fighter plane pilots than that in the transportation planegroup. Load induced by acceleration could be one of the main causative factors of temporomandibularjoint disorder.

AIM: To investigate the effect of electro-acupuncture (EA) at Zusanli (ST36) on proinflammatory factors induced-multiple organ dysfunction in rats with sepsis. METHODS: Sixty four male Wastar rats were used to develop the sepsis model by cecal ligation and puncture (CLP). The animals were randomly divided into 4 groups (n=16 in each group): CLP+EA (CLP/EA), CLP+sham EA (CLP/SEA), vagotomy+ CLP+SEA (VA/CLP/SEA) and vagotomy+CLP+EA (VA/CLP/EA). Zusanli point (ST36) was electroacupunctured with constant voltage (2-100 Hz, 2 mA for 0.5 h) 20 min after CLP surgery. Bilateral cervical vagotomies were performed in rats in VA/CL/SEA and VA/CLP/EA groups. Twelve hours after CLP, animals were sacrificed and liver, kidney and jejunum were harvested for evaluating the contents of tumor necrosis factor-α (TNF-α), myeloperoxidase (MPO) and diamine oxidase (DAO). The rate of water content (WCR) of the organs was determined. At the same time, the plasma levels of alanine aminotransferase (ALT) and creatinine (Cr) in each group were also detected. RESULTS: The levels of ALT and Cr in plasma, as well as TNF-α, MPO and WCR in organ tissues were markedly lower, and the activity of DAO in jejunum tissue was obviously higher than that in CLP/SEA group at 12 h after CLP (all P<0.05). The levels of ALT, Cr, TNF-α, MPO and WCR in VA/CLP/SEA group and VA/CLP/EA group were significantly higher, the activity of DAO was obviously lower than that in CLP/SEA group (all P<0.05). No statistical difference in all above measurements between VA/CLP/EA group and VA/CLP/SEA) group was observed (all P>0.05). CONCLUSION: The results indicate that EA at Zusanli point obviously decreases the levels of TNF-α in liver, kidney and jejunum tissues after CLP, and alleviates the tissue edema and dysfunction of those organs. Vagotomy decreases or eliminates the effects of EA, suggesting that activation of cholinergic anti-inflammatory pathway is one of the main mechanisms to induce the effects of EA at ST36 on CLP sepsis.

OBJECTIVETo assess the two-year outcome of initial endodontic treatment and evaluate the relationship between the treatment outcome and relevant factors.

METHODSA total of 296 patients with 371 teeth received initial endodontic treatment between January 2005 and December 2007 were included in the study. The teeth were treated using crown down technique, and followed for two years. The outcome was examined clinically and radiographically. The relevant factors, including pulp vitality, apical periodontitis, the number of tooth root, and state of root canal obturation, were analyzed.

RESULTS143 (176 teeth) from 296 patients (371 teeth) were followed for two years. 152 teeth (86.36%) with normal limits were assessed as "healed" (no apical periodontitis, no signs or symptoms). 24 teeth were assessed as "disease", 12 teeth were extracted and 12 teeth were retreated. The healing rate(HR) was statistically higher for vital teeth (95.38%) than that for devital teeth (81.08%). The HR of teeth without apical periodontitis (95.24%) was significantly higher than that with apical periodontitis (73.24%). Other factors were associated with different HR, but no statistical significance (P>0.05).

CONCLUSIONApical periodontitis and pulp vitality may be prognostic factors for outcome of initial endodontic treatment.

Objective Visceral pain in patients with inflammatory bowel disease (IBD) may be associated with the abnormal processing of pain in the central nervous system.The aim of the study is to investigate the characteristic changes of brain functions in the IBD patients using resting-state functional magnetic resonance imaging (rs-fMRI) with the amplitude of low-frequency fluctuation (ALFF) algorithm.Methods This study included 27 cases of IBD treated in our hospital from December 2015 to August of 2016 and 21 healthy volunteers as normal controls.We recorded the high-resolution structure imaging and rs-fMRI data, compared the brain activities of the two groups patients by ALFF analysis, and evaluated the correlation of the ALFF values with the clinical parameters of the IBD patients.Results Compared with the normal control group, the IBD patients showed significantly decreased ALFF values in the medial frontal gyrus, right putamen, right insula, left middle cingulate gyrus (MCC), and bilateral supplementary motor region (P<0.05), increased ALFF values in the middle frontal gyrus, left superior frontal gyrus, and medial prefrontal lobe region (P<0.05).The ALFF values in the inferior parietal lobule, precuneus and MCC of the IBD patients were correlated negatively with the blood sedimentation rate (r=-0.537,-0.588, and-0.588, P<0.05), disease course (P<0.05), and C-reactive protein (CRP) level (P<0.05), while that in the medial frontal gyrus positively with the CRP level (r=-0.623, P<0.001).Conclusion IBD patients have abnormal ALFF values in various brain regions, mainly in those involved in the processing of visceral pain and emotion.

Objective To prepare recombinant human adenovirus type 3 expressing Norovirus cap-sid protein gene(Noro-orf2). Methods The cDNA for Noro-orf2 was amplifed by RT-PCR from stool of in-fantile gastroenteritis and cloned into the adenovirus shuttle vector pBSE3CMV-egfp. The vector pBSE3CMV-Nor was linearized with EeoR Ⅴ and Not Ⅰ, and transformed into E. coil BJ5183 with lined edenovirus ge-nomic DNA pLasmid pBRAdv3 by Rsr Ⅱ. The identification of recombinant adenovirus plasmid pBRAdv3E3dNor was performed by PCR, enzyme digestion and DNA sequencing. Then pBRAdv3E3dNor was digested with AsiS Ⅰ and transfeeted into Hep-2 cells with LipofectAMINETM 2000 to package recombi-nant adenovirus particles. Results Noro-orf2 was successfully inserted into the shuttle vector. The recombi-nant adenoviral plasmid pBRAdv3E3dNor was generated by homologous recombination in E. coil BJ5183 and confirmed by PCR and enzyme digestion. The recombinant adenovirus was successfully packaged and puri-fied. Norovirus eapsid protein gene expression was confirmed in Hep-2 cells by immunecytochemistry assay. Conclusion The recombinant type 3 adenovirus expressing Norovirus eapsid protein gene was successfully constructed. This study laid a foundation for developing vaccine against Norovirus.

Objective To explore the value of virtual touch tissue quantification(VTQ) on the early diagnosis of gouty nephropathy.Methods 180 healthy controls and 109 gout patients including 57 cases with normal renal function,and 52 cases with gouty nephropathy were measured by VTQ in this study.The shear wave velocity (SWV) of renal cortex,renal medulla and renal sinus were measured using virtual touch tissue quantification(VTQ).The recorded SWV value was compared.Results In all groups,the SWV of renal cortex was the highest with significant difference (P ＜0.01).The SWV of renal cortex in gouty nephropathy group was higher than those in control group (t =0.342,P =0.026).The SWV of renal medulla and sinus in gout with normal renal function group and gouty nephropathy group were higher than those in control group,respectively (gout with normal renal function group:t =-0.311,-0.628; P =0.012,0.000;gouty nephropathy group:t =-0.369,-0.701 ; P =0.000,0.000).The SWV of renal cortex,medulla and sinus had no significant difference between gout patients with normal renal function and gouty nephropathy patients(t =0.117,-0.059,-0.073; P =0.232,0.575,0.523).Conclusions The VTQ technology could quantitatively evaluate tissue elasticity of the gout patients and provide evidence for the early diagnosis of gouty nephropathy.

Objective To explore the diagnostic value of MSCT in tumors of intra-abdominal cryptorchidism in children.Methods MSCT findings of 8 children with tumors of intra-abdominal cryptorchidism confirmed by surgery and pathology were analyzed retrospectively.Results Six tumors located in the right,2 (1 tumor of left cryptorchidism turned to the right abdominal) in the left.Eight children showed ovoid soft tissue tumor in abdomen.Three children displayed the long axis of the tumors consistent with regular descending course of embryonic testes.Six teratomas manifested as the cystic and solid mass with fat,calcification (ossification) insidey.Two yolk sac tumors manifested as the large cystic and solid mass with irregular necrosis and abundant tumor vessels.Conclusion The pathologic types of tumors for intra-abdominal cryptorchidism in children are different from adult.Most of them are teratomas or yolk sac tumors,and have some characteristics in MSCT.MSCT is helpful in diagnosis of tumor for intra-abdominal cryptorchidism with medical history.

Objective To study the clinical outcome of patients with fns-like tyrosine kinase-3internal tandem duplication (FLT3-ITD) positive acute myeloid leukemia (AML) treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT) and to explore the potential prognostic factors to patients' survival including transplant types or disease status.Methods A total of 314 AML patients in our center from October 2006 to October 2012 were retrospectively analyzed,among whom,54 patients were defined with FLT3-ITD positive.Survival rates and treatment-related mortality were further analyzed.Results For all 54 FLT3-ITD positive patients,the 3-year overall survival (3-OS) rate was 56％ and 3-year leukemia-free survival (3-LFS) rate was 47％.The outcome of haplo-identical HSCT was similar as that of sibling donors(3-OS rate:60％ vs 54％ ; 3-LFS rate:54％ vs 45％,respectively).There were 47 patients who received transplantation in first complete remission(CR1).The other 7 patients were of disease relapse or in CR2 before transplantation.Not surprisingly,patients in CR1 had better prognosis than those in nonCR1.Conclusions Allo-HSCT is an effective treatment for AML patients with FLT3-ITD positive mutation.The survival outcome of haplo-identical HSCT was comparable with that of sibling donors.Relapse of AML was the dominant factor related to the mortality of FLT3-ITD positive AML patients after allo-HSCT.

Objective To observe the biological activities of human doppel(Dpl) protein transiently expressed and Dpl-like protein PrP?32-121 on a human neuroblastoma cell line SH-SY5Y.Methods Recombinant mammalian expression plasmids containing human PRND gene and truncated PrP?32-121 fragment were generated by PCR.The expression and location of Dpl and PrP?32-121 post-transfection were observed by IFA.The cytotoxicity was measured by MTT analysis.Cellular apoptosis was investigated by flow cytometry and Western blot.Results Both Dpl and PrP?32-121 protein were expressed and mainly located on the cell membrane.Remarkable cytotoxicity was detected on SH-SY5Y cells after 24 h transfection.Meanwhile,more Annexin V/PI positively-stained cells as well as lower levels of cellular pro-caspase-3 and Bel-2 were detected in the cells receiving Dpl and PrP?32-121 expressing plasmids.Conclusion Dpl protein transiently expressed and PrP?32-121 can lead to the similar neural cytotoxicity,probably triggering the cell apoptosis program.
