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 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.

B7-H1, a recently described member of the B7 family of costimulatory molecules, is thought to be involved in tumor immune escape by inducing T-cell apoptosis. In order to investigate the relationship between B7-H1 and immune escape of bladder cancer, B7-H1 expression in 50 cases of bladder cancer was detected by using immunohistochemical method. Survival curves were constructed using the Kaplan-Meier method and independent prognostic factors were evaluated using the Cox regression model. Our results showed that the positive rate of B7-H1 immunostaining in normal bladder tissue and bladder cancer was 0 and 72% respectively. The expression of B7-H1 was strongly associated with the pathological grade, clinical stage and recurrence (P<0.05). The survival rate was significantly lower in patients with B7-H1 positive group than in those with B7-H1 negative group and multi-variable analysis revealed that B7-H1 could be regarded as an independent factor in evaluating the prognosis of bladder cancer. It is concluded that the expression of B7-H1 is strongly associated with neoplastic progression and prognosis of bladder cancer. The manipulation of B7-H1 may become a beneficial target for immunotherapy in human bladder cancer.
