Psychosomatic medicine studies on interaction between body and mind,etiology,pathology,diagnosis,and prevention of psychosomatic diseases.TCM has no concept of psychosomatic medicine,but studies result from research progress of psychosomatic medicine suggested that TCM had obvious advantages in treating these kinds of diseases.

Objective:To detect the effects of porcelain-fused-to-metal(PFM)crown on the periodontal tissue of the restored teeth,and the relationship between the levels of intedeukin(IL)-1β,aspartate transaminase(AST)and alkaline phosphatase(ALP)in gingival crevicular fluid(GCF)and the health condition of periodontal tissue.Methods:Among 28 patients,34 maxillary incisors with PFM crowns were selected for the study.There were 19 Ni-Cr PFM crowns and 15 Au-Pt PFM crowns.The contralateral homonymy natural teeth were healthy and treated as control teeth.The patients were followed up 6 to 8 months after restoring crowns.The values of IL-1β,AST and ALP in GCF were analysed.Results:The concentrations of IL1β and ALP were significantly higher in GCF of Ni-Cr PFM compared with those of control,whereas no significant difference in Au-Pt PFM group compared with that of control.The level of GCF-AST was higher in Ni-Cr PFM and Au-Pt PFM group than that of healthy control.Conclusion:Ni-Cr PFM crowns have negative influence on periodontal tissue,but Au-Pt PFM have little influence on periodontal tissue of the restored teeth.The activity of IL-1β,AST and ALP of GCF are sensitive to reflect the effect of PFM crowns of different materials on periodontal tissue.

BACKGROUND: In clinic, primary progressive aphasia is a dementia syndrome with the only or prominent characteristic of progressive decline in language function. In advanced stage, deficit of cognitive capability and loss of daily living ability would turn up while memory ability would be relatively preserved. The risk factors of primary progressive aphasia might include poor language ability in childhood and speech center involved by brain trauma.OBJECTIVE: To report the intracerebral image features of 1 case of primary progressive aphasia so as to disclose the general lesion area of the disease , the changes of intracerebral blood volume and metabolism , and connecting fibers among the language domains.DESIGN: Case-report.SETTING: Department of Intervention, Hongqi Hospital, Mudanjiang Medical College, Hei Longjiang Province.PARTICIPANTS: 1 case of patient with primary progressive aphasia,male, 56 years old and with senior high school culture, was in business before the onset of disease. He had "progressive decline in language ability for 3 years" as the main complaint and was diagnosed in Department of Neurology of Beijing Tiantan Hospital on March 20th, 2004. 3 years before that time, the patient could not tell the name of daily living appliances while his comprehensive ability was generally normal. 2 years before, he could still be in business. 1 year before, his language disorder was aggravated, auditory and comprehensive abilities gradually decreased and the changes of character turned up while he could take care of himself and had no obvious degeneration in memory ability. Neural systemic examination: systolic pressure was 130 mmHg and diastolic pressure was 80 mmHg, with clear consciousness, poor language expression ability, and nomenclatural disability while no abnormity was inspected in other neural systematic examinations. He was assessed as sensory aphasia with normal memory and intelligence according to aphasia assessment measuring scale made by the First Hospital of Beijing Medical University.METHODS: First, general magnetic resonance examination was taken to fix the lesion area of the patient. Then, functional magnetic resonance was carried out, which mainly included using magnetic resonance spectroscopy analysis to determine the metabolic rates of N-acetyl-aspartic acid, choline and creatine in the lesion area and then compare them with those in the contralateral corresponding area; Magnetic resonance perfusion imaging was carried out to detect regional cerebral blood volume, regional cerebral blood flow, average pass time and peak time of the contrast medium; Fibertracking method was used to track corticospinal tract and the amount of connecting fibers between left Broca and Wernicke areas and then compare them with those in the contralateral corresponding area.MAIN OUTCOME MEASURES: Detection of the metabolic rates of Nacetyl-aspartic acid, choline and creatine in lesion area and the contralateral area; Detection of regional cerebral blood volume, regional cerebral blood flow, average pass time and peak time of the contrast medium in lesion area and the contralateral area; Comparison of the amount of connecting fibers between left cortioospinal tract and left Broca and Wernicke areas.RESULTS: ①The results of general magnetic resonance: there was atrophy in left temporal and frontal lobes, especially significant in temporal pole, which was manifested as widening of cerebral sulcuses and fissures,thinness of cortex, and enlargement of frontal and temporal angles. ② The results of functional magnetic resonance: N-acetyl-aspartic acid, choline and creatine in left temporal lobe and anterior part of frontal lobe decreased more obviously and regional cerebral blood volume and regional cerebral blood flow in these areas decreased,while average pass time and peak time of the contrast medium in these areas slightly increased as compared with those in the conitralateral areas; fraction of anisotropy values and the tracked fasciculus in left corticospinal tract decreased, and the connecting fibers between Broca and Wernicke areas also decreased as compared with those in the contralateral area.CONCLUSION: The lesion area of primary progressive aphasia is mainly located in left temporal and frontal lobes where low perfusion, low metabolic state and decrease of connecting fibers between Broca and Wernicke areas were shown as compared with those in the contralateral area, which might be the pathogenesis of this case of primary progressive aphasia.

Objective To investigate the application of middle segment pancreatectomy (MSP) in treating benign pancreatic tumors and the effect on exocrine function.Methods From Jan.2010 to Feb.2013,19 cases with benign pancreatic tumor undergoing MSP were enrolled in our study.Pre-and postoperative pancreatic exocrine function were studied.Results No perioperative death happened.The tumor diameter was 4.2 to 7.0cm,operative time was 80 to 320 mins,and intraoperative blood loss was 200 to 1000 ml.The retained pancreas was＞l.5 cm at pancreatic head side,and＞5 cm at pancreatic caudal side.Three days after surgery,the peritoneal drainage and amylase was 2.5-12.5 ml and 568.4-1013 IU/L,respectively.Seven days after surgery,the peritoneal drainage and amylase was 1.0-19.8 ml and 45.4-76.3 IU/L,respectively.The postoperative hospitalization stay were 10 to 25 days.Three cases (all single anastomosis) had pancreatic fistula after surgery and healed after 3 months without undergoing surgery again.Patients were followed up for 2 months to 3 years.All patients have a good life quality,without new-onset diabetes and cancer recurrence.MSP had no side effects on pancreatic exocrine function.Conclusion MSP is safe and feasible in treatment of benign pancreatic tumors.

Objective To study the relationship between abnormal blood pressure distribution characteristics and the influencing factors for the prevention of hypertension and low blood pressure to provide reference. Methods Regarding the Guangzhou City adult group as the research object,we analyzed the distribution of the adults abnormal blood pressure in age, gender , urban and rural areas, as well as of occupations. Results The detection rate of blood pressure abnormalities was 15.9 % , which accounted for 12.4% of hypertension, 3.5% of hypotension. On the whole, the detection rate of hypertension was 18% in rural, higher than 9.8% in urban. The detection rate of hypotension in rural areas was 2.3% , 4.0% in urban. The detection rate of hypertension of men was high than that of women, and the detection rate of hypertension gradually increased by the age increased. At the same time, hypertension and hypotension was significantly affected with the factors of education, urban and rural areas, obesity and so on. Conclusion The detection rate of hypertension is high in rural areas than that in urban,and men than women, and the detection rate of low blood pressure is on the opposite. Both of them is significantly affected by the factors of education, urban and rural areas, obesity and so on.

[Objective]To explore the dependability between heredity and hallux valgus.[Method]A total(1 491) cases of family heredity of hallux valgus patients were investigated,the ages of these patients,ages of onset,ages of aggravation,hallux valgus angles were analyzed statistically.[Result]Conclusive family medical history exists in 69.48% of the(1 491) hallux valgus patients.There was distinguished difference between the patients with family history and those without heredity background on visiting ages,ages of onset,ages of aggravation;but no any difference between these two groups of patients on hallux valgus angles.[Conclusion]Heredity factor is the main cause of hallux valgus.It can influence only the onset of hallux valgus,but not the severe degree of latter.The patients with family history are earlier than those without heredity background about visiting ages,ages of onset,ages of aggravation.

After intracerebral ventricular administration of GLP-1 in NS or 30% glucose to rats,their effects on blood glucose and glucose regulatory hormones were observed. The results demonstrated:1. Intracerebral ventricular administration of GLP-1 in NS didn't influence plasma stucose, insulin and glucagon secretion.2. Intracerebral ventricular administration of GLP-1 in 30% glucose increased plasma glucose concentration significantly and decreased insulin concentration,but no change of glucagon concentration. This experiment showed that GLP-1 might participate in CNS regulation of pancreatic islet hormonesecretion.
