Objective To investigate the expression of ?-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid(AMPA) receptor subunit proteins GluR2/3 in the postnatal rat cochlear nucleus(CN), and the relationship with the auditory brainstem response(ABR).Methods The thresholds of ABR of different age SD rats were recorded respectively,and the expression of GluR2/3 in CN was detected with FITC-immunocytochemistry.Results ①P1w SD rats did not show ABR wave, and there was no significant difference in the ABR threshold among P4w,P9w and P15w SD rats. ②GluR2/3 was expressed in all sorts of neurons of CN of every postnatal groups, the expression of P4w rats was denser than that of P1w, P9w and P15w rats. The immunostaining of P4w rats was located at the cell membrance, while P9w and P15w rats in the endochylema majoritily. Conclusion The different expression and distribution of GluR2/3 in different age rat CN may be involved in the development of auditory centre.

Objective:To observe the GluR2 expression in rat inferior colliculus (IC) in different developmental stages , and to investigate its developmental change and relationship with the synapse development.Method: The expression of GluR2 and synaptophysin(SYP) in IC were detected by double immunofluorescence method.Result:①All sorts of neurons in IC expressed GluR2 in every postnatal groups, and the GluR2 expression in P6w groups was higher than that in other groups .②The expression of GluR2 were different in different subnucleus of IC.③All sorts of neurons in IC expressed SYP in every postnatal groups, and the SYP expression in P6w groups was higher than others. ④The expressions of GluR2 consistented with the expression of SYP in IC.Conclusion:The developmental changes of GluR2 and SYP expression in the rat IC may be involved in the development and plasticity of auditory center.

Objective To characterize clinical features,antimicrobial susceptibility and the outcome of nosocomial Acinetobacter baumannii meningitis.Methods All patients with nosocomial meningitis due to Acinetobacter baumannii in 2nd Affiliated Hospital Medical School of Zhejiang University between January 2010 and October 2011 were retrospectively reviewed.Results During the study period,40 patients of this nosocomial infection were identified,who came from neurosurgery ward (19 cases,47.5％),neurosurgieal intensive care unit (18 cases,45.0％),emergency intensive care unit (2 cases,5.0％) or intensive care unit (1 case,2.5％).All the patients had a history of recent neurosurgical procedures. Fever and disturbance of consciousness were the major manifestations,and cerebrospinal fluid examination showed elevated white blood ceil count and protein,and reduced glucose.All isolated pathogens were resistant to the first line antibiotics.The fatality rate was high. Conclusions The most common risk factor for nosocomial Acinetobacter baumannii meningitis is neurosurgery. Resistance to the first line antibiotics is common among all pathogens isolated.The prognosis of the meningitis is poor.

Objective The aim of this study is to compare the gains accomplished from different tympanoplasty based upon a review of patient records.Methods The charts of 137 patients who underwent different tympanoplasty operations were reviewed.They were divided into three groups.Group I,26 cases(26 ears) of tympanoplasty with mastoidectomy;group II,61 cases(62 ears) of tympanoplasty with mastoidectomy;group III,48 cases(49 ears) of myringoplasty.The hearing outcomes after dry ear were analyzed.Nonparametric statistics was used to determine group differences.A probability value of P

OBJECTIVE:To investigate sodium intake via drug used by hypertensive inpatients during hospitalization. METH-ODS:290 inpatients with hypertension were collected from vasculocardiology department of our hospital between Jan. and Oct. 2013. The types of sodium-containing drugs and sodium-intake during hospitalization were analyzed statistically. RESULTS:275 pa-tients with hypertension were prescribed 38 sodium-containing drugs(94.8%);82.7% were administered by iv gtt with a average drug treatment course of 6.7 days(average hospitalization days of 6.8 days). Solvent containing sodium such as 0.9% Sodium chlo-ride injection and Creatine phosphate sodium for injection were the most sodium donors. 43.3% patients’sodium intake exceeded upper limit of 2 g/day recommended by WHO. CONCLUSIONS:Hypertensive inpatients are prescribed too much sodium-contain-ing drugs,and less intravenous solutions and less adjuvant medicines should be took to decrease sodium intake. Only when prospec-tive benefit are greater than risk,the patients can be prescribed sodium-containing drug prescription.At the same time,manufacturers should annotate the content of sodium in package inserts,which is convenient for physicians to choose drugs.

Three-orientation medical talent training mainly include humanistic quality cultivation, professional quality and physical and mental quality. With professional ability as the guidance of profes-sional quality education requires students not only to grasp skilled medical technology, but also have the ability to enhance the medical technology. Based on the orientation of training target, this research mainly from habit set, authority set, set the multitude and empirical mind-set four aspects in this paper, the critical thinking, and put forward problems from finding problems, and expounds the innovative thinking of concise problem.

BACKGROUND:Restoring the stability of the spine has become the consensus of spinal surgery. The canaloplasty technology has been continuously improved, but how can we get the good clinical effect of the canaloplasty, and the price affordable, many domestic scholars have to try al kinds of the improved operation methods. OBJECTIVE:To evaluate the clinical application value of cannulated screws fixation in canaloplasty. METHODS:From February 2011 to February 2013, total y 24 patients with spinal disease treated by canaloplasty using cannulated screw were retrospectively analyzed, of which 12 cases of cervical stenosis, 2 cases of intraspinal tumor in thoracic and 10 cases of intraspinal tumor in lumbar. Al patients were fol owed up after treatment. Postoperative CT and MRI were done in al patients. Clinical symptoms and radiographic changes were observed after treatment. The Japanese Orthopaedic Association score and the spinal canal cross-sectional area measurement were conducted in the patients with cervical stenosis between the preoperation and postoperation. Visual analog scale score was evaluated in patients who have the tumor in the thoracolumbar spine between the preoperation and postoperation. RESULTS AND CONCLUSION:Al patients had no complications such as nerve or blood vessel damage. Al patients were fol owed up 12 to 24 months. Imaging evaluation showed that internal fixator was stable without the hol ow screw loss or displacement. The bone grafting in groove reached bone fusion. There was no occurrence of lamina col apse or“re-close of door”. The Japanese Orthopaedic Association score and spinal canal cross-sectional area of patients with cervical stenosis during the fol ow-up after 12 months of treatment were significantly superior to those in preoperation (P<0.01). After 12 months of treatment, Japanese Orthopaedic Association scores showed that the excel ent rate of classification assessment was 92%. During the fol ow-up after 12 months of treatment, the visual analog scale of patients with thoracolumbar tumor improved from (8.2±1.6) points before treatment to (2.3±1.3) points at the first year after discharge (P=0.004 2). These results suggest that the application of cannulated screws in the canaloplasty can not only enhance the stability of the rear pil ar, and can improve the healing rate of osteotomy, and has the characteristics of inexpensive, easy to operate, and repair effect is good.

Objective To investigate anti-ulcerative drug use in patients undergoing arthroscopic operation against stress ulcer. Methosds A total of 297 patients undergoing arthroscopic operation during Jan. to Aug. 2013 in our hospital were recruited and retrospectively analyzed with Excellspreadsheet. Results Among 297 patients in the study, ninety-four patients (31.6%) used AUD before operation, most (94.9%) administered by intravenous, and drug utilization index was 1.35. Ninety-eight point nine patients used proton pump inhibitors (PPIs) in which Lansoprazole was prescribed most. Conclusion This study highlights the overuse of PPIs in patients undergoing arthroscopic operation.
