Objective To evaluate the accuracy of monitoring the neuremuscular blockade intraoporatively by transcutaneous electrical stimulation at the P6 acupuncture point. Methods Thirty-five patients, ASA Ⅰ - Ⅲ, BMI≤35 kg/m2 scheduled for abdominal surgery were selected. Anesthesia was induced by sufentunil 0.2-0.3 μg/ kg iv, propofol 2,5-3.5 mg/kg iv. Neuromuscular monitoring was performed by TOF Watch SXR at the P6 acupuncture point on the left forearm and ulnar nerve on the right. The current intensity and gain were recorded frem all the patients;onset time, recovery time of TOF ratio 25% and TOF ratio 90% of atrucurium were also obtained by TOF stimulation on the P6 acupuncture point and the ulnar nerve in patients who were administered a single bolus of atracurium 0.5 mg/kg iv during operation. Controlled ventilation commenced after endotracheal intubation. Results There were no significant differences between the P6 acupuncture point and the ulnar nerve in stimulus intensity or gain ( P > 0.05 ). There were no significant differences between the P6 acupuncture point and the ulnar nerve in onset time, recovery time of TOF ratio 25% and TOF ratio 90% (P > 0.05).Conclusion Transcutaneous electrical stimulation at the P6 acupuncture point can be used to monitor neuromuscular blockade intraoperafively.

Objective To study CT diagnostic value of benign and malignant salivary gland lesions.Methods CT features in 36 cases with pathologically-proved salivary lesions were retrospectively analyzed.There were 19 cases with benign tumors,5 cases with chronic inflammation,1 case with tuberculosis and 11 cases with malignant tumors.Results Benign tumors were regular in 17 and well-defined in 16.All cases with chronic inflammation and 1 case with tuberculosis were regular but ill-defined.Benign lesions showed homogeneous or inhomogeneous density.Of all 11 malignant tumors,7 cases presented ill-defined margin with irregularity in shape,infiltration of adjacent subcutaneous fat tissue and disappearing of epiderm.Salivary glands enlarged and looked like "cast form" in malignant tumors.Most of the malignant tumors and benign tumors presented inhomogeneous density.Conclusion CT scan is of important value in the diagnosis of salivary diseases.

Objective To investigate the clinical value of the bedside color Doppler in the assessment infants with periventricular-intraventricular hemorrhages (PIVH).Methods Sixty-eight cases of PIVH newborns and 156 healthy newborns were involved in the study,dynamic monitoring were undergone within a week after birth.The middle cerebral artery(MCA) hemodynamic parameters of velocity systolic (Vs),velocity diastolic(Vd) and resistance index (RI) were recorded,and the differences of the parameters were compared between different grades as well as those of the normal newborns at 1 d,4 d and 7 d after born.Results Total 68 PIVH infants were diagnosed by bedside color Doppler accurately.Prevalences of premature and low birth weight infants were higher than term infants and normal birth weight children,respectively (P <0.05).Vs and Vd of 4 groups of children with PIVH showed an increasing trend in a week after born.The differences of Vs between grade Ⅰ and normal newborns in 4 d and 7 d were not statistically significant (P> 0.05),the differences of the other three groups compared with normal newborn group in1 d,4 d and 7 d were statistically significant (P <0.05).Vd of grade Ⅱ newborns within 7 d were greater than those of other 4 groups (P <0.05),grade Ⅲ and grade Ⅳ within 7 d were less than healthy newborns (P <0.05).The difference of RI between all groups were not statistically significant (P > 0.05).Conclusions The diagnostic accuracy rate of PIVH by bedside Doppler is high and the dynamic monitoring of neonatal hemodynamics could provide an important basis for assessing the occurrence and development of PIVH.

An analytical method for simultaneous determination of five quinolones in spicy soup was developed. Spicy soup samples were firstly extracted by EDTA-Mcllvaine buffer at pH 4, then purified and concentrated by a novel Packed fiber solid phase extraction ( PFSPE ) coulumn. The extracted liquid supernatant was loaded onto the column, rinsed with water, and then eluted with 2% ammoniated methanol. The mobile phase was methanol-water-phosphoric acid (25:75:0. 1, V/V, adjusting the pH to 2. 8 with triethylamine) . These analytes were quantified by high performance liquid chromatography-fluorimetric detector( HPLC-FLD) at excitation and emission wavelength of 280 nm and 450 nm respectively. Recoveries of spiked quinolone antibiotics in spicy soup were from 72 . 1% to 110 . 3% with intraday relative standard deviation (RSD) between 1. 6% and 4. 3% and inter-day RSD from 2. 0% to 4. 3%. Limit of detection (LOD) and limit of quantitation(LOQ) were from 1. 2 to 5. 4 μg/L and from 3. 9 to 18 μg/L, respectively. The method could be applied to determine the quinolones in spicy soup.

Objective To investigate CT image features of pleomorphic adenoma and adenolymphoma,and to improve the diagno-sis accuracy.Methods CT data of 1 3 cases of pleomorphic adenomas and 9 cases of adenolymphomas confirmed by pathology were retrospectively analyzed and compared.Results All 1 3 cases of pleomorphic adeonoma were solitary lesions,in which 1 1 cases were located in the non posterior inferior quadrant,and 1 1 cases showed persistent or delayed enhancement,with “slowly forward and slowly quit”enhancement performance.In all of the 9 cases of adenolymphoma,3 cases were multiple lesions.In total of 1 3 lesions, 9 lesions were located in the posterior inferior quadrant,and 9 lesions were significantly enhanced in the arterial phase and enhance-ment was decreased in the delayed phase,which showed “quickly forward and quickly quit”.Conclusion CT image features of pleo-morphic adenoma and adenolymphoma are different.Most of lesions can be diagnosed correctly before surgery by using image fea-tures with clinical information.

Objective To investigate the current status of nursing undergraduate students′ self-differentiation and career adaptability and analyze the correlation of the two, so as to provide a reference for nursing educators to offer employment guidance. Methods The Undergraduate Self-Differentiation Scale and The College Students′Career Adaptability Questionnaire were used to investigate 341 nursing undergraduates. Results The mean scores of the self-differentiation and the career adaptability were (3.70±0.60) points and (3.60±0.42) points, respectively. It showed that the total score of self-differentiation and its each dimension were positively correlated with career adaptability, the Pearson correlation coefficients were career adjustment 0.26, career interpersonal 0.38, career curiosity 0.32, career confidence 0.39, career concerns 0.27, career control 0.46, and the coefficients between two total scales were 0.46 (all P<0.05). Conclusions The self-differentiation level of nursing undergraduates could affect their career adaptation level, and clinical nursing educators can take corresponding measures to improve their career adaptability based on the characteristics of nursing students′self-differentiation.
