To combine "the rule of military medical measurement" with the current situation of medical treatment quality control, the foundation, important component and necessary condition of medical treatment quality control was described. Some idiographic advices of intercoordination and communication in medical measurement institution, the direction and training of special technique, and how to develop compulsion coerciveness checking in base course were given. These are valuable for insuring medical treatment facility in hospital.

Objective To study the middle ear mucosa of guinea pigs with tympanosclerosis by electron microscope and try to obtain some insights into the feature and pathogenesis of tympanosclerosis.Methods Eight healthy variegated guinea pigs were devided into 2 groups.Six(8 ears) guinea pigs were subjected to inoculation of 1×10~8/L of staphylococcus aureus solution 100 μl into the middle ear cavities under the microscope.All the guinea pigs were observed for more than 6 months with no farther treatment.For electron-microscopic studies,the mucosa tissues were taken from the tympanic mucosa in 6 guinea pigs (8 ears) with tympanosclerosis from various sites,while the middle ear mucosa of two healthy guinea pigs (4 ears) were taken as a control.Results Uhrastructural examination of the normal middle ear mucosa revealed a few collagen fibers,normal morphous of fibrocyte,rough endoplasmic reticulum and mitochondria,and there was no lysosome.However,the tympanosclerosis specimens showed that irregular deformation,elongation,and degeneration of fibrocytes and oval nucleus were darkly stained,lots of mitochondria and lysosomes gathered into the cytoplasm around the nuclear and cystic expansion of the endoplasmic reticulum.In the submucosa extracellular matrix,there were a large number of collagen fibers containing lots of amorphous high-density electron-rich body.Conclusion Electron-microscopic studies of the middle ear mucosa of guinea pigs with tympanosclerosis revealed evident proliferation of collagen fibers,and calcifications were seen in the structures such as extracellular matrix vesicle,lysosomes,myelin structures within lipid granules,which mainly in extracellular matrix vesicles.

Objective To investigate the diagnosis of intracranial artery fenestration and its other vascular anomalies with CT angiography ( CTA ) . Methods The image data of 653 patients examined with head CTA and 39 patients diagnosed as intracranial artery fenestration in Zhongshan Hospital Affiliated to Sun Yat-sen University from January 2013 to January 2014 were analyzed retrospectively. The incidence, location,morphology of intracranial artery fenestration, and other vascular anomalies were analyzed. Results (1) In 653 patients,39 (5. 97%) with 41 artery fenestrations were detected. The detection rates of basilar artery fenestration was 3. 37% (n=22),vertebral artery fenestration was 0. 31% (n=2),anterior cerebral artery fenestration was 1. 22% (n =8),anterior communicating artery fenestration was 0. 61%(n=4),and middle cerebral artery fenestration was 0. 76% (n=5),respectively. The post-circulation fenestration was mainly convex lens type (66. 67%,n =17),the anterior-circulation fenestration was mainly fissure type (76. 47%,n=24),and there was significant difference (χ2=7. 411,P<0. 05). (2) In the 39 patients,22 complicated other vascular anomalies. Most of them were unilateral or bilateral fetal-type posterior cerebral arteries (n=10),and followed by aneurysms (n=5). The locations of 5 aneurysms were far from the fenestration,3 located in the communicating segment of internal carotid artery,1 in the top of basilar artery,and 1 in the M2 segment of bilateral middle cerebral arteries. Conclusion CTA can intuitively and clearly reveal the intracranial artery fenestration and other vascular anomalies. But there is no significant correlation between arterial fenestration and vascular anomalies.

VE: Chitosan and sodium tripolyphosphate were used as Complex matrix material for preparing pellets loading sodium diclofenac and its properties were studied. METHODS Chitosantripolyphosphate sodium polyelectrolyte was prepared according to the principle of static electricity polymerization. Its properties and structure characteristics were further investigated. The preparation process, effective factors and the optimal condition for the pellets loading sodium diclofenac were studied. RESULTS IR indicated that the structure of compound contained -NH3+-O-P group. DTA demonstrated that polyelectrolyte had an exothermic peak. There was no interaction between the drug and expedient. SEM showed that the surface of the pellets was regular, dense and the structure of the surface wasn't consistent with the inner. The pellets prepared by this method were uniform, round, well-distributed, hardy, good-mobility and its average diameter was about 10mm. CONCLUSION Chitosan-tripolyphosphate sodium polyelectrolyte could be used as a good matrix material for preparing pellets.

0.05).(2) The volume range of 25 hepatocellular tumors was 395.16～2747.7 ml using diameter measurement and 203.10～1463.19 ml using MSCT 3D measurement before the operation.There was significant difference of the data in these two groups using t-test (t=7.689, P

The paper puts forward the design and application of an imaging analysis system for micro-particles.The structure of the system,design theory and its application are discussed in the paper.

Objective To assess the displaying of the cystic artery and the cystic duct in calculus cholecystitis patients using MSCT.Methods One hundred and three patients with calculus cholecystitis (the experimental group)and 71 patients with non-gallbladder disease (the control group)performed the cystic artery and the cystic duct imaging using MSCT.The data in two groups were recorded and statistical analyzed.Results (1)The display rate of the cystic duct were 93.2% (96/103)in the experimental group and 100% (71/71)in the control group with the significant difference between the two groups (P <0.05).7 cases whose cystic ducts could not displayed in the experimental group were all the acute cholecystitis,and the display rate of the cystic duct in the acute cholecystitis was 77.4%(24/31).The display rate of the cystic artery were 100% in both the experimental and control group.(2)The variation rate of the cystic duct running were 10.4% (10/96)in the experimental group and 18.3% (13/71 )in the control group with no significant difference between the groups (P >0.05).The variation rate of the cystic artery running were 13.5% (13/96)in the experimental group and 1 5.5% (1 1/71)in the control group.There was no significant difference between the groups (P >0.05).Conclusion The cystic duct and the cystic artery could be evaluted well in calculus cholecystitis using CT.The displaying of the cystic duct is relatively poor in acute cholecystitis.

Objective To observe the effect of interventional therapy of urokinase on sudden hearing loss.Methods65 patients with sudden hearing loss were divided into the treatment group (n=35) and control group (n=30). The patients of the treatment group were treated with urokinase pouring into vertebral artery accordingly into labyrinthine artery in order to improve internal ear microcirculation. Those of the control group were treated with routine drug dropping in vein. All patients of two groups were examined by pure tone test before and after treatment and the therapeutic effect of two groups was compared.ResultsIn the treatment group, the audition of 21 cases recovered, 12 cases got 15～30 dB increasing, 2 cases increased <15 dB. In the control group, the audition of 10 cases recovered, 4 cases got 15～30 dB increasing, 9 cases increased <15 dB and 7 cases had no obvious improvement. There was a significant difference between effects of two groups ( P<0.05).ConclusionThe effect of urokinase on sudden hearing loss is superior to routine drug dropping in vein.

Purpose: To investigate the mechanism of acupuncture treatment of diabetic peripheral neuropathy. Methods: Acupuncture therapy was used to treat diabetic peripheral neuropathy, and compared with oral calcium antagonist and vitamin therapy by random control observation.Electromyography was performed for analysis at the same time. Results: Acupuncture treatment alleviated symptoms such as extremity numbness, pain and paresthesia in varying degrees in diabetic patients with peripheral neuropathy. The results of electromyography showed a marked improvement in motor and sensory conduction velocities. Conclusion: It is indicated that acupuncture therapy is markedly superior to oral calcium antagonist and vitamin therapy in clinical effect on diabetic peripheral neuropathy, and electromyographic recovery.
