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 investigate the effects of dexmedctomidine pretreatment and postconditioning on renal ischemia-reperfusion (I/R) injury in rats.Methods Thirty-two male Wistar rats,aged 3-4 months,weighing 220-300 g,were randomly divided into 4 groups ( n =8 each):sham operation group ( group S),I/R group,dexmedetomidine pretreatment group (group Pre) and dexmedetomidine postconditioning group (group Post).The rats were anesthetized with phenobarbital sodium 65 mg/kg.Renal I/R was produced by occlusion of both renal pedicles for 60 min followed by 48 h reperfusion.Dexmedetomidine 50 μg/kg was given intraperitoneally at 30 min before ischemia and at the beginning of reperfusion in Pre and Post groups respectively.The concentrations of serum creatinine and blood urea were determined at 0,24 and 48 h of reperfusion (T1-3).The renal tissues were obtained at the end of reperfusion for microscopic examination and detection of apoptosis by TUNEL assay.Acute kidney tubular necrosis was scored and apoptosis index (AI) was calculated.Results Compared with group S,the concentration of serum creatinine and blood urea at T2.3,and acute kidney tubular necrosis score and AI were significantly increased in I/R,Pre and Post groups ( P ＜ 0.05).Compared with I/R group,the concentration of serum creatinine and blood urea at T2.3,acute kidney tubular necrosis score and AI were significantly decreased in Pre and Post groups ( P ＜ 0.05).Conclusion Both dexmedetomidine pretreatment and postconditioning can attenuate renal I/R injury through inhibition of cell apoptosis in rats.

ObjectiveTo compare the diagnostic value of X-ray, CT, MRI, and ultrasound in primary synovial osteochondromatosis ( PSO ).Methods The imaging data of X-ray, CT, MRI, and ultrasound of 42 patients with 44 knees with PSO proved by surgery and pathology were retrospectively collected and analyzed. ResultsThe Plain X-ray demonstrated 197 calcific nodules in 28 joints, 96 ossific nodules in 24 joints, and 5 mixed type nodules in 3 joints. Compared with the data of surgery and pathology,36 joints (81.8 ％, 36/44) were diagnosed correctly by X-ray. The CT showed 8 big cartilaginous nodules in 5 joints, 255 calcific nodules in 30 joints, 146 ossific nodules in 28 joints, and 16 mixed type nodules in 7 joints.Twenty-four knees underwent volume rendering technique reconstruction which displayed the quantity, size, shape, and position of non-cartilaginous nodules clearly. Compared with the data of surgery and pathology, 40 joints (90. 9％ , 40/44)were diagnosed correctly by CT. The MRI demonstrated 8 big cartilaginous nodules in 5 joints, 70 small cartilaginous nodules in 4 joints, 248 calcific nodules in 29 joints,146 ossific nodules in 28 joints, and 16 mixed type nodules in 7 joints. All nodules displayed low signal in DWI and there was no enhancement. Compared with the data of surgery and pathology, 43 joints (97.7％,43/44) were diagnosed correctly by MRI. The ultrasound showed 8 big cartilaginous nodules in 5 joints,70 small cartilaginous nodules in 4 joints, 232 calcific nodules in 30 joints, 142 ossific nodules in 28 joints,and 16 mixed type nodules in 7 joints. Compared with the data of surgery and pathology, 43 joints (97. 7％,43/44) were diagnosed correctly by ultrasound. ConclusionsThe less common manifestations of the PSO require multimodality imaging to make the diagnosis. Multimodalities (X-ray,CT, MRI and ultrasound) are particularly useful in fully characterising PSO and to allow for appropriate clinical planning.

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.
