The infratemporal fossa abscess is an irregularly shaped cavity, situated below and media to the zygomatic arch. It consists of masseter and nervus vascularis, etc. Comparatively speaking, the low position of the infratemporal fossa has almost freed the patient from dental, nasal,ocular and aural source of pain. So facial acupuncture is more likely to cause the infection. But it is also possible that the patient get cryptogenic infection of maxillofacial cavity, the treatment of which needs further study.

PurposeTo analyze the sonographic and the histological features of special types of breast malignant tumors in order to explore preoperative ultrasound diagnosis. Materials and Methods Seven cases of special types of breast malignant tumors confirmed by pathology were retrospectively investigated by ultrasound. The sonographic and histological features of the lesions were reviewed. The ultrasonogram manifestations of the breast anatomy and the lesions were observed and recorded.Results Among 7 cases, there were 2 cases of papillary carcinoma, 3 cases of mucinous carcinoma, and 2 cases of lymphoma. Microscopically, the papillary carcinoma had clear boundaries with infringing mesenchyme, and the tissues were papillary and dense. The mucinous carcinoma had cancer cells floated in mucus lake. The primary breast lymphoma was diffused large B-cell type with focal lesion. For sonography type of breast, there were 3 cases of fatty types, 1 case of fibroglandular-1 and 3 cases of fibroglandular-2. The papillary carcinoma was hypoechoic in 2 cases, one of them was expansive growth with large size. Two cases of mucinous carcinoma were hypoechoic without accompanying sound attenuation in 1 case and with accompanying acoustic shadow due to calcification in the other case. Lymphoma was apparent anechoic and cystoid.Conclusion Special types of breast malignancies have different sonographic features and histological features from the common invasive ductal carcinoma. It has high clinical significance to enhance the understanding of rare malignant breast tumors.

Objective To explore the effectiveness of the timed up and go test (TUGT) and the maximum walking speed test (MWST) in evaluating stroke patients' motor function.Methods Twenty-two stroke patients were assessed using the TUGT and MWST,and the temporal-spatial parameters of their gait were also assessed.The correlations among the TUGT times,walking speed and the gait parameters were quantified using Pearson correlation coefficients.Results The TUGT time was (18.57±7.41) s,significantly correlated with step length and velocity (P＜0.05).Walking speed showed a significant positive correlation with step length,velocity and step length (P＜ 0.05).The TUGT times were negatively correlated with walking speed (r=-0.712,P=0.000).Conclusion The MWST and TUGT both can assess stroke patients' motor function effectively.

BACKGROUND: To search for an alloxenogeneic bone with good load bearing function and osteoblastic activity for treating bone defects is an important study issue. We have made a comparative study on its biome chanical characteristics and found that there was no significant difference in maximum load stress, maximum pressure as compared with fresh bone of the same size. Clinicians are concerned about the osteoblastic activity and whether the osteoblastic activity can be reserved after human allogenous a cellular bone (HAB) loaded with bone marrow stromal cells (BMSCs). OBJECTIVE: To investigate the experimental effect of HAB loaded with induced BMSCs, and observe the cellular adherence and growth as well as detect its osteoblastic activity. DESIGN: Single sample experiment. SETTING: Second Affiliated Hospital of Harbin Medical University. MATERIALS: This experiment was conducted at the Experimental Center of the Second Affiliated Hospital of Harbin Medical University between January 2003 and August 2004. HAB was obtained from fresh corpse iliac bones (donated voluntarily). METHODS: Connective tissues and cell compounds of the iliac bones were removed by processing with hydroperoxide andether solution and sterilized for preparing HAB. BMSCs from living femoral shaft bone marrow were cultured immediately in ordinary and mineralized medium containing DMEM, fetal bovine serum, dexomethasone, β-glycerophophate and ascor bic acid. Proliferation and differentiation of bone stromal cells were deter mined by detecting the level of alkaline phosphatase (ALP) and osteocalcin (OCN) in the culture medium. Induced bone stromal cells solution was condensed and implanted within HAB scaffold. Cellular osteoblastic activ ity was determined through morphological observation under the light mi croscope and electron microscope as well as biochemical index detection. MAIN OUTCOME MEASURES: ① Detection results of ALP and OCN of BMSCs/HAB composite. ② Histological observation results of BMSCs/ HAB composite. RESULTS: ① Iliac bone block cells were cleaned with good reservation of bone matrix. ② The level of ALP and OCN of MSCs was higher after in ducing for 8 days than that in control group [MSCs after induction: (181.54±40.01) nkat/L, (7.2±1.3) μg/L. There was no method to detect the level in control group, P ＜ 0.05]. ③ BMSCs were adhered and grew well in HAB scaffold. CONCLUSION: HAB loaded with induced BMSCs has an excellent os teogenic function in vitro and shows an effective potential as a good bone tissue engineering material.

In 4 602 subjects for routine check-up,blood uric acid,total cholesterol,triglyceride,high density lipoprotein-cholesterol,and low density lipoprotein-cholesterol were determined.Results showed that the overall prevalence of hyperuricemia in Nanning,Guangxi was 19.8％ (28.8％ in male,9.4％ in female).Blood uric acid and lipids in hyperuricemia group were higher than those in normal uric acid group(all P＜0.01).Serum uric acid had a positive correlation with total cholesterol,triglyceride,low density lipoprotein-cholesterol,but it was negatively correlated with serum high density lipoprotein-cholesterol.The prevalence of hypercholesterolemia was 30.8％,and that of hypertriglyceridemia was 22.2％.Logistic multi-factor regression analysis showed that men,high total cholesterol,triglyceride,and low density lipoprotein-cholesterol could be independent risk factors for hyperuricemia,and that high density lipoprotein-cholesterol was a protective factor.The prevalence of hyperuricemia in population of Nanning,Guangxi during health examination is high.Hyperuricemia is closely associated with dyslipidemia.Timely intervention of hyperuricemia can reduce the related diseases effectively.

Objective Through the investigation and analysis to "Chinese Medical Digest" and its relative periodicals to get a general idea of the survival and situation of these periodicals and to establish the pattern for their survival and development. Methods Such methods as telephone consultation, questionnaire survey, interview, and conference discussion were adopted to collect the relative information of medical digest periodicals and thus an analysis was made upon it. Results There were 18 kinds of "Chinese Medical Digest" periodicals originally. Of all these 18 kinds of the periodicals, 6 kinds are still publishing, 10 kinds have transferred its nature to first-hand literature periodical, and 2 kinds have ceased their publishment. Conclusion As a result of the computer, the network and the full text database development, the survival of medical digest periodicals are endangered. However, regarding to the different domain of subject, different reforming measures should be taken.

Objective To investigate the impact and significance of the vagus nerve intervention on the atrial electrical emodeling.Methods 30 mongrel dogs were given metoprolol in order to eliminate the effects of sympathetic nerve on atrial electrical remodeling;observe the atrial effective refractory period (ERP) and atrial fibrillation susceptible window(VW) in the high right atrial(SA) and coronary sinus (CS) by the vagus nerve stimulation(VS) or vagus nerve stimulation(Non-VS) before and after using atropine and after atrial electrical remodeling was observed.Results Before using vagus nerve blocking agents atropine,ERP shortened significantly [(54.83 ± 46.23) ms] and VW increased significantly [(19.86±13.23) ms] after VS,this time with atrial fibrillation-prone ; After using atropine,ERP increased significantly [(112.33 ± 9.63) ms] under VS,did not induce atrial fibrillation; After atrial electrical remodeling,the value of ERP was no significant difference under basis and VS (t =2.116,0.853,all P ＞0.05).Conclusion VS can increase the atrial electrical remodeling,an increase of atrial fibrillation susceptibility;vagus nerve block can reduce atrial electrical remodeling and atrial fibrillation susceptibility decreased.

Objective To determine the clinical value of the multi-slice spiral CT virtual endoscopy (CTVE) for the detection of biliary pancreatic junction lesions. Method MSCT and virtual endoscopic reconstruction were performed in 30 healthy volunteers, 18 cases of common bile duct stones and 7 cases of ampullary carcinoma to observe patterns of duodenal papilla and measure its size.Results Reconstructed image of CTVE showed that the normal duodenal papilla was nodular in 16,shaped like "V" in 8 "Y-shaped" in 6 of the healthy volunteers. Its diameter was (0.84±0.17)cm. In the patients with common bile duct stones, it was nodular and its diameter (1.72±0.32)cm. In the patients with ampullary cancer, it was of irregular protruded type and its diameter (2.30±0.85)cm.There was significant difference among the 3 groups in the overall mean values (P＜0.01). Conclusion CTVE is a convenient, non-invasive and precise clinical examination to observe the shape of duodenal papilla and determine its size.
