Objective To evaluate the utility of carbapenem inactivation method (CIM) in detecting carbapenemase-producing Acinetobacter baumannii.Methods A total of 121 strains of A. baumannii were identified and subjected to antimicrobial susceptibility testing by VITEK compact. Carbapenem inactivation method (CIM) was applied to detect the carbapenemase in the A. baumannii strains. The OXA-23 type carbapenemase-encoding genes were analyzed by common PCR method.Results Six-eight of the 121 strains showed resistance to imipenem and meropenem. PCR showed that 65 of the 68 strains carried OXA-23 gene. CIM was positive in 66 of the 68 strains. And 52 of the 121A. baumannii strains were susceptible to imipenem and meropenem. PCR showed that OXA-23 gene was negative in 49 of the 52 strains. CIM was negative in the 52 strains of non-carbapenemase-producing A. baumannii. Only one strain was resistant to imipenem but susceptible to meropenem. CIM was negative but QXA-23 was positive for this strain. The sensitivity and the specificity of CIM was 94.2% and 98.1% respectively in detecting carbapenemase-producing A. baumannii.Conclusions The results of CIM were consistent with the results obtained by PCR to detect the encoding gene of OXA-23. CIM is inexpensive, easier to operate and interpret than PCR method. CIM is applicable to detect OXA-23 type carbapenemase rapidly inA. baumannii.

Objective To explore the ultrasound imaging characteristics of thyroid papillary carcinoma complicated cervical lymph node tuberculosis, and to elucidate the key points of ultrasound diagnosis and to distinguish with cervical lymph node metastasis of papillary thyroid carcinoma.Methods In total, 1 5 well-documented cases of papillary thyroid carcinoma diagnosed definitely were selected, and there were 6 cases of concomitant lymph node metastasis. The ultrasonography of lymph node enlargement was analyzed, and the differences of the ultrasonographic characteristics between lymph node tuberculosis and metastatic lymph node including the location, swelling, calcification, blood flow and regional nodal liquefaction. Results Thyroid papillary carcinoma complicated with cervical lymph node tuberculosis was often found in the areas of Ⅲ,Ⅳ and Ⅴ, especially in the area of Ⅴ. Variety of echo was mixed in tuberculous of lymph node, and the echo was inhomogenous. The tuberculosis of lymph node calcification was patchy inhomogeneous distribution.The echo in part of liquefaction of lymph node tuberculosis was cottony weak. The flow signal of tuberculous lymph appeared the surrounding or internal punctate distribution,and the soft tissue was echogenic and disorder around the lymph node tuberculosis. Conclusion When ultrasonography examination is performed in the patients with the thyroid papillary carcinoma complicated with cervical lymph node enlargement, the history should be considered to analyze the ultrasound characteristics to dignose by observing the lesions of the surrounding soft tissues.

Objective: To observe the effect of needling different points on functional reconstruction of wrist following cerebral apoplexy. Methods: Forty apoplexy cases were randomly allocated into four groups, 10 in each. Cases in group A were treated by needling the extensor muscle motor points. Cases in group B were treated by needling alternating extensor-flexor muscle motor points. Cases in group C were treated by needling Jianyu (LI 15),Binao (LI 14), Shousanli (LI 10) and Waiguan (TE 5). Cases in group D were treated by needling Jianyu (LI 15), Binao (LI 14), Shousanli (LI 10), Waiguan (TE 5), Chize (LU 5) and Neiguan (PC 6). The motor functions of affected upper limbs were evaluated on the surface electromyography (SEMG), Fugl-Meyer function scale and Barthel ADL (Activities of Daily Living) indexes. Results: Needling alternating extensor-flexor muscle motor points can significantly increase the peak value (MAX) of the upper limb SEMG, integrated electromyogram (IEMG), Fugl-Meyer motor function value and Barthel ADL indexes.Conclusion: Needling different points may produce different effects on wrist function following cerebral apoplexy. Needling alternating extensor-flexor muscle motor points can obtain an exact treatment effect.

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) are conveniently cultured and separated in vitro because theirimmunogenicity is low. Therefore, BMSCs are suitable for cell transplantation. Research has shown that BMSCs are potential to repair neurological defect. OBJECTIVE: To determine whether in vitro cultured BMSCs can be transplanted to repair peripheral nerve injury or not, and to investigate its mechanisms. DESIGN, TIME AND SETTING: Randomized controlled animal study This study was performed in Department of Toxicology, Public Health College of Jilin University from March 2006 to March 2007.MATERIALS: Fifty healthy female Wistar rats aging 2 months and six 1-week-old female Wistar rats were used for extraction of BMSCs. Rabbit-anti-nerve growth factor (NGF) monoclonal antibody was provided by Santa Cruz Company. METHODS:BMSCs were separated and cultured with adherent method. In the 3rd generation, BMSCs were preiabeled with bromodeoxyuridine (BrdU) 48 hours before transplantation. Fifty healthy Wistar rats were selected to prepare sciatic nerve crush injury models with clamping method.Subsequently, rats were randomly divided into transplantation group and control group, with 25 rats in each group. Rats in the transplantation group underwent transplantation of BrdU-labeied BMSCs at nerve injured sites; while, the same volume DMEM was injected into rats in the control group. MAIN OUTCOME MEASURES: Injured nerve in the transplantation group suffered from anti-BrdU staining 1, 2, 4, and 6 weeks after surgery. Distal injured nerve in both groups suffered from NGF immunohistochemical staining 1, 2, 4, and 6 weeks after surgery. Image analysis system was adopted to analyze integrated absorbance of positive expression. Gait analysis was performed every week after surgery to measure sciatic nerve function index, and it was also adopted to measure regenerated nerve conduction velocity 6 weeks after surgery. Subsequently, amount and inner diameter of medullated nerve fibers were calculated after luxol fast blue staining, while wet weight of experimental-lateral gastrocnemius muscle and cross section area of muscle fiber were measured at the same time. RESULTS: Fifty rats were included in the final analysis. BrdU-labeled positive cells could be found at injured nerve in the transplantation group 1, 2, and 4 weeks after surgery. Integrated absorbance of NGF protein expression in the transplantation group was significantly higher than that in the control group 1 and 2 weeks after surgery (P < 0.01), but there were no significant differences between the two groups 4 and 6 weeks after surgery (P > 0.05). Sciatic nerve function index in the transplantation group superiorly recovered to that in the control group 3-6 weeks after surgery. Furthermore, 6 weeks after surgery, nerve conduction velocity, amount and diameter of medullated nerve fibers, wet weight and cross section area of gastrocnemius muscle in the transplantation group were significantly higher than those in the control group (P < 0.05-0.01). CONCLUSION: BMSCs can be transplantated into injuried nerve tissue, and promote the recovery of nerve function in the micro-enviroment, improve NGF expression in an early phase may be one of its mechanisms.
