OBJECTIVE:To provide reference for rational use of narcotic drugs and category Ⅰ psychotropic drugs. METH-ODS:The utilization of narcotic drugs and category Ⅰ psychotropic drugs in clinical wards of Zhengzhou People's Hospital during Jan.-Dec. in 2014 was analyzed statistically in respects of drug types,department distribution medication purpose,DDDs,DDC, DUI,etc. RESULTS:A total of 16 kinds of narcotic drugs and one kind of categoryⅠpsychotropic drugs were used in 28 981 pre-scriptions of narcotic drugs and category Ⅰ psychotropic drugs in our hospital in 2014;A total of 16 kinds of narcotic drugs and one categery Ⅰ psychotropic drugs were used,narcotic drugs mainly included Sufentanil citrate injection(7 816 prescriptions)and Fentanyl citrate injection (5 104 prescriptions),and category Ⅰ psychotropic drugs mainly was Ketamine hydrochloride injection (190 prescriptions). Narcotic drugs and category Ⅰ psychotropic drugs were mainly used in anesthesia department,pain depart-ment and medical oncology department. Main purpose of narcotic drugs and category Ⅰ psychotropic drugs were intraoperative an-esthesia,cancer pain and postoperative analgesia. Top 3 drugs in the list of DDDs were Sufentanil citrate injection,Fentanyl citrate injection(0.1 mg)and Remifentanil for injection. CONCLUSIONS:The utilization of narcotics and category Ⅰ psychotropic drugs are generally rational in the hospital;the doctors can grasp the indication and medication principle,and use drugs rationally accord-ing to disease condition.

Forty eight patients with knee joint lipohemarthrosis underwent X-ray, CT, MRI and ultrasonography examinations, the diagnosis was confirmed by knee operation or puncture.The findings of 4 imaging methods were compared.Plain radiographs displayed fracture lines in 39 cases and fat-liquid layer of suprapatellar bursa in 40 cases, it displayed suprapatellar fat-liquid layer in 5 out of 9 occult fracture cases.CT displayed fracture lines in 48 cases and joint lipohemarthrosis in 48 cases; 3D imaging showed fracture lines better.MRI displayed fracture lines in 45 cases and joints lipohemarthrosis in 48 cases, and also showed the intracapsular structure injury.Ultrasonography revealed fracture lines in 15 cases and joint lipohemarthrosis in 48 cases, lipohemarthrosis was displayed in 7 out of 9 occult fracture cases.All 4 diagnostic imaging methods have advantages and disadvantages for diagnosis of lipohemarthrosis, and should be chosen on the basis of clinical needs.

Objective To study the diagnostic value of MR coronal iterative decomposition of water and fat with echo asymmetry and least-squares estimation(IDEAL) water imaging in the far later lumbar disc herniation(FLLDH).Methods A retrospective analysis of pre-operative routine CT axial imaging and MPR post-processing,conventional MR axial plane,sagittal plane and IDEAL imaging was performed in 10 patients with pathologically FLLDH.The above images were observed to find whether it could clearly show the spatial relationship outline of the nucleus pulposus and the nerve root,including the number of affected nerve root(1 or 2),and the compressed part(dorsal root ganglion,postganglionic nerve root or preganglionic nerve root),and the morphological changes of the compressed nerve root(distortion,thinning,enlargement),and were compared with surgical results.Results Surgery showed 2 cases with extra-intervertebral foramen herniation,2 cases with intra-intervertebral foramen herniation,6 cases with mixed herniation.Nine cases involved 1 nerve root,and 1 case involved 2 nerve roots.The conventional CT axial plane could roughly show the local relationship between nucleus pulposus and the nerve root.On conventional CT axial plane,9 cases were diagnosed correctly but 1 case of herniation of extra-intervertebral foramen shifting cephalic to the lower vertebral level was missed.Seven cases of the compressed nerve root were identified with difficulty,2 cases showed obliteration of the fat space and displacement of the nerve root.The spatial relationship of the nucleus pulposus and the nerve root was more visualized by CT MPR images than conventional CT images,but the image was less clear and it could not display the full view.Ten cases on CT MPR images were diagnosed correctly.Nine cases involved 1 nerve root,and 1 case involved 2 nerve roots,the image finding was obliteration of the fat space.Eight cases involved distortion of the compressed nerve root,3 cases involved thinning of the compressed nerve root,1 case involved thickening of the nerve root,6 cases were with no change or no confirmed diagnosis.MR regular scans could roughly show the local relationship of the nucleus pulposus and the nerve root and it is superior to the conventional CT axial scanning.On the conventional axial plane,7 cases of the compressed nerve root were identified with difficulty,3 cases showed obliteration of the fat space and displacement of the compressed nerve root.On the sagittal plane through the intervertebral foramen:5 cases of mixed herniation and 2 cases herniation of intra-intervertebral foramen showed intervertebral disc into the intervertebral foramen,with displacement or annihilation of the compressed nerve root.Two cases of extra-intervertebral foramen herniation were without positive findings.On MR coronal IDEAL water imaging,it could clearly and accurately show the spatial relationship of the nucleus pulposus and the nerve root.It is superior to the conventional CT axial image,CT MPR image and the conventional MR scanning.Ten cases were diagnosed correctly.Four cases were identified as compressed DRG,5 cases were identified as compressed postganglionic nerve root,1 case was identified with compressed L4 postganglionic nerve root and compressed L5 preganglionic nerve root.Ten cases were all identified with distortion of the compressed nerve root,6 cases were identified with the compressed thinning nerve root,and 2 cases with the compressed thickening nerve root.The other nerve roots were not compressed.Conclusion MR coronal IDEAL water imaging is a good tool to show the spatial relationship of nucleus pulposus and the nerve root in FLLDH patients,and it possesses diagnostic value.

Objective To explore the ultrasound appearance of primary synovial osteochondromatosis (PSO) of the knee. Methods Thirty-eight cases with PSO were confirmed by pathology, their ultrasound features were analyzed retrospective. Results Two hundred and sixty calcify nodules showed medium echo and several motting or bolus strong echo. Two hundred and eighty-nine ossify nodules showed slightly strong echo or strong echo,or only showed arc strong echo with rear sound shadow near nodules. Twenty-six mixed type nodules showed promiscuity moderately strong echo or with rear sound shadow. Forty introsynovium cartilage lesser nodules showed synovium thickening and similar round low echo nodules,30 sursynovium lesser nodules showed high echo, with a pedicel connected to synovium, can shift deform or sway because of the pressure from transducer, often concomitance other type nodules. Ten cartilage greater nodules showed similar round or lobulated low or medium echo tuberculum. Conclusions Ultrasound can show multiple nodules of PSO of the knee, especially noncalcific nonage smaller cartilage nodules. It is helpful for clinicians to decide more reasonable operation strategy.

Objective To observe the effect of puerarin on the level of malondialdehyde (MDA) and myeloperoxidase (MPO) in myocardial in scalded rat.Methods Eighty-eight Wistar rats were randomly divided into the recovery group (group R,n=40),the treatment group (group T,n=40) and the control group (group C,n=8) . The rats in the recovery and the treatment groups were subjected to 30% TBSAⅢdegree scald.Myocardial tissue samples from the group R and group T were harvested at 1,3,6,12,24 postburn hours for the determination of MDA and MPO. The morphological change in the myocardial tissue was observed with transmission electronic microscope.Results (1)In group R,MDA、MPO went up 1 hours after burns,and all attaining the top at 12 hours post burn (P＜0.01).(2)In group T,the indexes above had the same trends as group R.But comparing with group R,MPO and MDA were much lower at 1,3,6,12 hours (P＜0.05 or P＜0.01).(3)Comparing with group R,the altrastructural changes were obviously alleviated at 24 hours in group T.Conclusion The production of MDA,MPO in severely burned rats can be inhibited by puerarin,which was beneficial in the management of myocardial injuries after severe burns.

Objective To explore the correlation between ultrasonographic findings and relevant technical factors in traumatic lipohemarthrosis. Methods Fifty-two patients with traumatic lipohemarthrosis underwent ultrasonic examination in supine position (26 in unbent, 16 in external rotary position, 10 in unbent and 45° rotation) before operation, and 22 of them underwent dynamic examination. Findings of ultrasography were compared with manifestations of MRI and CT regarded as gold standard.Results Fifty-two patients with traumatic lipohemarthrosis were diagnosed correctly. The best effect of ultrasonic examination of lipohemarthrosis was observed on suprapatellar bursa. Superior border of patella were showed well in supine straight position, then turned to the level of patella, and the structure below patella were showed badly. The best posture was in supine genuflex position with 45° rotation when the joint effusion presented, by which thicker layer liquids could be displayed than in straight position. Three layer liquids could not be displayed synchronously in mild external rotary rest position of lower extremity, and the combination of findings at internal and external side were favorable to the diagnosis. Liquids bed changed from one layer to two layers and then to three layers, from fuzzy to clear gradually in dynamic examination.Conclusion Ultrasonic manifestations of traumatic lipohemarthrosis are closely correlated to the position, posture and arresting time during examination.

Objective: To study the distribution of levofloxacin in the serum and ascites in patients with cirrhosis and to evaluate its efficacy in treatment of patients with spontaneous bacterial peritonitis(SBP). Methods:（1）Concentration of levofloxacin in the serum and ascites was detected with HPLC in 7 patients with cirrhosis at different time (in the serum: 0.5, 1, 1.5, 2 and 12 h;in the ascites:2, 4, 6 and 12 h). （2）The effects of levofloxacin were observed in treatment of 30 patients with SBP. Results:（1） Levofloxacin was determined in serum and ascites of patients with cirrhosis, whose concentration depended on the duration after oral administration. In serum: tmax was 1.5 h and cmax was (3.913±1.388) μg/ml. In ascites: tmax was 6.0 h and cmax was (2.520±1.213) μg/ml. The levels decreased gradually after reaching peak concentration, then stabilized from 12 h.（2）The symptoms and signs were significantly improved in patients with SBP treated with the levofloxacin. Conclusion: After the oral administration, levofloxacin can both distribute in serum and ascites, and it is efficient in the treatment of the patients with SBP.

Objective To investigate the braking time in diagnosis of lipohemarthrosis by ultrasound. Methods Experiment group:After 20 tubes containing fresh blood and pig marrow were uniformly mixed, they were instantly continuously detected by high-frequency linear array transducer in fixed-area at short-interval.Clinical group: Ten walking patients with lipohemarthrosis were examined with continuous detection by ultrasound,CT and MR before operation.Results Experiment group: Cloudy echo and slowly floating up of lipoids were detected at the beginning.After 2.7 to 3.7 minutes (average 3.17 minutes), the liquid was divided into two layers with vague boundary.After 5.3 to 8.0 minutes (average 6.75 minutes) ,the liquid was divided into 3 layers with thickening serum laye.Clinical group: Ultrasound findings: Cloudy medium echo was detected at first.After 2.0 to 4.0 minutes (average 3.08 minutes),the liquid was divided into two layers.After 4.4 to 10.0 minutes (average 6.92 minutes) , the liquid was divided into 3 layers with thickening serum layers.Three knees showed fracture line and 2 knees with occult fracture were diagnosed as lipohemarthrosis.CT and MR findings: Ten knees showed fracture line in CT examination,of which 7 knees showed double liquid-liquid layer and 3 knees showed single liquid-liquid layer in the suprapatellar bursa.Ten knees showed fracture line in MR examination,6 knees showed double liquid-liquid layer and 4 knees showed single liquid-liquid layer in the suprapatellar bursa. Conclusions The best braking time in diagnosing lipohemarthrosis by ultrasound can be shorten to 10 minutes and the necessary braking time is 2 to 4 minutes.
