Objective To observe and evaluate the effect of ultrasound guided percutaneous ethanol injection for hyperparathyroidism secondary to chronic renal failure. Methods Fifty-three patients with secondary hyperparathyroidism in Nanjing General Hospital Military Command from January 2011 to May 2013 were treated by percutaneous ethanol injection. The echogenicity, size and blood supply of parathyroid glands were observed by color Doppler ultrasound before and after treatment. Parathyroid hormone (PTH) and volumes of parathyroid glands were analyzed and compared with non-paired t test. Results Before treatment, the parathyroid gland volume was (5.28±0.84) cm3. The enlarged parathyroid glands had homogeneous hypoechogenicity and abundant blood supply, and the PTH was (1041.6±37.1) ng/L. After treatment, the size of solitary parathyroid gland was (3.93±0.67) cm3 which did not change significantly compared with that before treatment. The echogenicity of parathyroid glands enhanced and blood supply decreased after injection ethanol into solitary parathyroid. PTH [(509.2±27.6) ng/L] decreased obviously (t=3.792, P < 0.05). Conclusion Color Doppler ultrasound guided percutaneous injection of ethanol has an important role in the treating of secondary hyperparathyroidism and the curative effect can be observed timely.

Objective To compare different susceptibility testing methods of tigecycline against Acinetobacter baumannii and Klebsiella pneumoniae.Methods Fifty carbapenem-resietant A.baumannii (CRAB) strains and 49 K.pneumoniae strains were collected from Tianjin Medical University General Hospital during January and March 2012.Minimum inhibitory concentration (MIC) and inhibitory zone diameters for tigecycline were determined by broth microdilution,Vitek-2,MTS and disk diffusion methods.The results of Vitek-2,MTS and disk diffusion methods were compared with those of broth microdilution method.Results According to FDA standards,the susceptibilities of CRAB and K.pneumoniae to tigecycline determined by broth microdilution,Vitek-2 and MTS were 94.0％/91.8％,68.0％/91.8％ and 90.0％/91.8％,respectively.For CRAB isolates,the essential agreement (EA) and categorical agreement (CA) produced by Vitek-2 and MTS were 94.0％/72.0％ and 92.0％/90.0％.MICs determined by Vitek-2 were 1-2 dilutions higher than the reference method in 33 (66.0％) strains,and those determined by MTS were higher in 16 (32.0％) strains and lower in 11 (22.0％) strains.For K.pneumoniae isolates,the EA/CA produced by Vitek-2 and MTS were 95.9％/98.0％ and 83.7％/91.8％,respectively.MICs determined by Vitek-2 were 1-3 dilutions lower than the reference method in 17 (34.7％) strains,and those determined by MTS were 1-3 dilutions lower than the reference method in 39 (79.6％) strains.None of thetwo methods produced very major error (VME) and major error (ME) against two kinds of isolates.The results were determined by disk diffusion method using different breakpoints according different isolates.For CRAB,using ≥14 mm/≤ 10 mm as breakpoint,CA was 94.0％,which was higher than the breakpoint recommended by Jones et al (≥16 mm/≤12 mm,CA was 82.0％) ; and for K.pneumoniae,using the ≥ 14 mm/≤ 10 mm as breakpoint,CA was 93.9％,higher than the FDA Enterobacteriaceae breakpoint (≥ 19 mm/≤ 14 mm,CA was 67.3％).Conclusion For CRAB strains,MTS produces better consistence with broth microdilution,with several higher or lower MIC results.For K.pneumoniae strains,Vitek-2 has better correlation with reference method,with several lower MIC results.The consistence between disk diffusion method and broth microdilution is comparatively lower,and the breakpoint should be adjusted according to different bacteria.

Objective To evaluate the role of AMP-activated protein kinase (AMPK)-dependent autophagic signaling pathway in ketamine-induced reduction of diabetic neuropathic pain (DNP) in rats.Methods Sixty male Wistar rats,aged 3 months,weighing 200-250 g,were equally randomized into 5 groups using a random number table:control group (C group),normal saline group (NS group),ketamine group (K group),ketamine + Compound C group (KC group),and ketamine + 3-methyladenine (3-MA) group (KM group).DNP model was established by intraperitoneal injection of streptozocin (STZ)65 mg/kg in anesthetized rats.Four weeks later,the equal volume of normal saline,ketamine 10 mg/kg,ketamine 10 mg/kg + Compound C1 mg/kg,and ketamine + 3-MA 2 μl were injected intraperitoneally once a day for 7 consecutive days in NS,K,KC and KM groups,respectively.The mechanical paw withdrawal threshold (MWT) was measured on 8th day.The rats were then sacrificed,and the lunbar segment (L1-5) of the spinal cord was removed for determination of the expression of AMPKαt,Beclin-1,microtubule-associated protein 1 light chain (LC) 3B (by Western blot) and dendritic spine density in the dorsal root ganglia.Results Compared with group C,the MWT,expression of AMPKα,Beclin-1,and LC3B,and dendritic spine density were significantly decreased in group NS (P＜0.05).Compared with group NS,the MWT,expression of AMPKαt,Beclin-1,and LC3B,and dendritic spine density were significantly increased in group K (P＜0.05).Compared with group K,the MWT,expression of AMPKα,Beclin-1,and LC3B,and dendritic spine density were significantly decreased in KC and KM groups (P＜0.05).Conclusion Activation of AMPK-dependent autophagic pathway is involved in ketamine-induced reduction of DNP in rats.

Objective To explore the clinical significance of the coagulation and fibrolysis parameters changes for the knowledge of complicated thrombosis after chemotherapy in malignant lymphomas. Methods Morning fasting anti-coagulation blood samples were taken to detect plasma prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and thrombin time (TT) with automatic coagulation analyzer in 71 hospitalized malignant lymphomas and 20 normal controls. The plasma D-dimer levels of the two groups were detected with immunoturbidimetry. Results The levels of plasma APTT, Fib and D-dimer in 71 malignant lynphomas were (30.44±1.43) s, (3.28±0.20) g/L, (297.05±56.59) μg/L respectively, which were significantly higher than those in normal controls at the levels of (23.72±0.76) s, (2.57±0.22) g/L, (94.50±26.07) μg/L respectively (P ＜0.05). The coagulation and fibrolysis parameters were of no statistic differences between the normal controls and lymphomas of stage Ⅰ and Ⅱ (P ＞0.05). The APTT and Fib levels in lymphomas of stage Ⅲ and Ⅳ were higher than those in normal controls and lymphomas of stage Ⅰ and Ⅱ (P ＜0.05). There are 7 malignant lymphomas complicated venous thrombosis . Of the 7 cases, the FIB and D-dimer levels were higher than those of stage Ⅰ and Ⅱ, furthermore the D-dimer levels were higher than those of stage Ⅲ and Ⅳ. Conclusion The abnormalities of coagulation and fibrolysis parameters occurred in malignant lymphomas with requirement of periodic monitoring. After chemotherapy, the lymphoma patients had a high incidence of venous thrombosis, which need early prevention for prolongation of the survival.
