RESUMEN
This article expounds on the necessity of the introduction of comparative imaging in bone and joint imaging teaching according to the bone and joint imaging teaching situation and modern medical radiographic features.Meanwhile,it discusses the application of comparative imaging in bone and joint imaging teaching from aspects of teaching method,teaching effect evaluation and prospects of the comparative imaging.
RESUMEN
Objective To investigate the BUN content and ALT activity in cataract at serum and Lens by Fuming tablets.Methods The BUN content in serum and cens of the model group,treatment and control groups was detected by Urease-Berthelot method,while ALT activity in serum and Lens of the model,freatment and control group was delected by Laishi method.Results The BUN contemtin lens of treatment group Ⅰ and Ⅱ was lower than that in control and molel group(P
RESUMEN
Objective To improve the recognition of abnormal image of soft tissue in cheeks. Methods Images of 47 cases with abnormal soft tissue in cheeks were retrospectively studied. Results (1) 15 cases were originated from soft tissue of the cheeks in which 8 cases were benign and 7 cases were malignant.6 cases were invaded by maxillofacial affection nearby,in which 1 case was benign and 5 cases were malignant.26 cases were involved by lesions of jaw bones,including benign tumor of jaw bones in 9, malignant tumor of jaw bones in 14 and chronic osteomyelitis of jaw bones in 3 and all had bony destruction; (2) According to originated position,21 cases were not originated from jaw bones,in which there were 5 cases (23.8%) with destruction of jaw bones;(3)In the 26 cases with abnormal soft tissue of cheeks originated from jaw bones, 9 were benign tumors in which all the soft tissue masses were mainly localized inside of the jaw bones, while 14 cases were malignant tumors in which all the soft-tissue masses were localized both inside and outside of the jaw bones. There was remarkable difference between the two groups(P=0.000).All 9 cases of benign tumors appeared as dilated destruction of jaw bones, while in the 14 cases of malignant tumors, 12 cases showed osteolytic bone destruction and the other 2 cases showed ossific bone destruction,there was significant difference between the two groups(P=0.000).Conclusion CT and MRI are of significance in judging original position, extent and differential diagnosis between benign and malignant lesions of abnormal soft tissue in cheeks.
RESUMEN
Objective To explore the relationship between the post-thoracotomic wound infection and nutritional status.Methods The patients treated with thoracotomy were divided into the simple wound infection group(n=15) as the experimental group and the phase Ⅰ healed group (n=15) as the control group.On the fifth day after operation, the sero-albumin quantity and cumulative nitrogen balance were recorded respectively. The statistical data were given the test.Results Every average index of sero-albumin in the experimental group was lower than the control group. Among them, the total protein comparison had statistical significance (P0 05) and transferrin comparison had statistical difference (P
RESUMEN
Objective To evaluate the effects of Radix Astr agali combined with prednisone and i mmunosuppressant for primary nephrotic syndrome (PNS)in adults and to compare the effects o f Radix Astragali in various prepata tions for PNS.Methods Randomized controlled trials were a pplied for systemic reviews.Electr onic and manual retrieve of Medline,Embase,Cochrane Library,CBMdisc a nd CEBM/CCD and relevant medical jou rnals in China were applied to search the RCTs of Radix Astragali,non -specific treatment,glucocorticoids and i mmunosuppresants for PNS,and the RCTs were analysed with RevMan 4.1.Results There were 14randomized controlled trials with 524cases involved.Meta-analysis showed that Radix Astragali could in crease the therapeutic effect of pre dnisone and immunosuppressant for PNS and re-duce its recurrence.Radix Astragali also had an effect in decreasing 24-hour proteinuria content and the pla sma levels of total cholesterol and albumin.There were no differences between single injection and compound decoction.Asymmetry showed in"Funnel plot"may be related to publication bias,l ow quality of methodology and small -size in sample.Conclusion Radix Astragali and its prescriptio n may become a prospect therapy for PN S and its recurrence and the com-bination of traditional Chinese med icine and western medicine can be more effective for PNS.The dedinite effect of Radix Astragali for PNS will be further con firmed by multiple -center,large -s ample randomized controlled trial.
RESUMEN
Objective:To observe effects of Cuttle-Bone on blood inorganic phosphorus and parathyroid hormone(PTH)in patients of uremia in hemodialysis.Methods:74 cases of uremia in hemodialysis were randomly divided into a control group,a cuttlefish bone treatment group and a calcium carbonate treatment group.The control group did not take any conjugation agent of phosphorus. The cuttlefish bone treatment group were treated with oral administration of cuttlefish bone powder 3.0g in each meal and the calcium carbonate treatment group with chewing calcium carbonate tablets 1.5g in each meal.They all were treated for 3 months. Results:After treatment,blood inorganic phosphorus and PTH decreased(P0.05),with less effect on blood calcium(P
RESUMEN
The experimental acute spinal cord injury (SCI) was performed in 10 rabbits at L_1 level using the method of compredssing the abdominal lateral of spinal cord. The rabbits were treated with naloxone (2mg/kg/h) intravenously 45 minutes after SCI and treated continually for 4 hours. In the control group, equal volume of saline was administered. The ascending and descending conductive function of spinal cord was measured by mortor evoked potential (MEP) and cortical somatosensory evoked potential (CSEP). The result showed that amplitude of the MEP and CSEP peaks came to a normal level 2 hours after SCI and were significantly higher (P
RESUMEN
The changes of the activities of succinic dehydrogenase (SDH) and acid phosphatase (ACP) in spinal motoneurons after ventral cord compression were observed with microphotometry in 15 rabbits.The first lumbar segment of the spinal cord was compressed epidurally with 50g weight for one minute.It was found that statistically significant changes of both SDH and ACP took place immediately and 2 hours after cord compression (P
