Objective To set up an antibody-capture ELISA method to detect the Japanese encephalitis virus(JEV)antibody.Methods ELISA plate was coated with the monoclonal antibody which was specific to the envelope protein epitope E39 of JEV,JEV SA14-14-2 strain as the source of antigen was used to absorb the monoclonal antibody,the absorbed virus used to capture the JEV'S antibody.The antibody that captured ELISA was established.The indirect ELISA method using the virus particles from cell culture was compared with coating ELISA plate,105 clinical serum were checked.Results The background in indirect ELISA assay could not be abscised,positive and negative serum diluted in a ratio of 1:10,1:100,1:1000,the relative value of A posative/A negative were 1.02,0.99,1.13,all<2.1.But the antibody-captured ELISA method when the serum dilution was 1:10,1:100,the A posative/A negative were 3.57,2.94,all>2.1;when the dilution was 1:1000,the A posative/A negative was 1.42,<2.1,it meant the method could distinguish the positive and negative serum efficiently when the dilution Was 1:100,the background problem in indirect ELISA assay could be solved.Antibody-capture method was used to check 105 serum samples,the A posative/A negative over a range of 0.257～0.321(0.262±0.050),all<2.1,no positive sample found.Conclusion The antibody-capture ELISA method has been preliminary set up with a high specificity,capable of quickly identifying JEV from other virus.

Objective To establish a method for simultaneous determination of icariin and naringin content in bushen huayu extract by HPLC. Methods Reverse-phase high performance liquid chromatography ( RP-HPLC ) separation was performed one C18 column (4.6 mmí250 mm,5 μm).The mobile phase was acetonitrile containing 0.2%H4PO3(pH=2.9). Gradient elution with a flow rate of 0. 8 mL·min-1 was applied to achieve the separation. The detection wavelength was set at 269 nm,and the column temperature was 30℃. Results Icariin had a good linear range from 0. 3-3. 0μg (r=0. 999 9),the recovery rate was 105. 6%,and RSD was 0. 95%. Naringin was linear within the range of 0. 12-1. 20 μg (r=0. 999 9). The recovery rate was 94. 0%and RSD was 0. 52%. Conclusion The method is simple,stable,accurate,and reproducible,which can be used as the quality control standard for bushen huayue extract.

Objective To observe the imaging features of coronary sinus (CS) and its tributaries in Chinese by using multislice computed tomography (MSCT).Methods One hundred patients [74 men,26 women,average age (58.10?1.78)] were scanned by MSCT,3D images reconstructed and the vessels courses evaluated.Results The CS and great cardiac vein (GCV),middle cardiac vein (MCV) were visualized in all patients,as well as left posterior vein (LPV) was showed only in 82 patients.The average width of CS was (1.98?0.41),(1.08?0.06)cm,and the average area was (2.144?0.37)cm~2.The diameter of MCV was (0.49?0.04) cm and its angle with CS was (73.98?5.82)?.The GCV remained in the same axis as the CS in the left atrioventricular groove,its average diameter was (0.35?0.03)cm.The LPV's average diameter was (0.33?0.05)cm and its average angle with GCV was (74.32?7.81)?.The MCV and LPV in most of the patients drained to the CS at an angle less than 90?,and this angulation might cause technical difficulties during inserting a left ventricular pacing lead.Conclusion MSCT is a simple and feasible method to visualize the imaging features of CS and its main tributaries,and in the clinical,it can be used to evaluate patient's coronary vein system before cardiac interventional procedure such as left ventricular pacing lead implantation.

Objective To evaluate curative effects of percutaneous laser disc decompression(PLDD) in the treatment of discogenic low back pain.Methods A total of 36 patients with discogenic low back pain was included in the study.The PLDD was performed by using the DIOMED semiconductor laser treatment,with a power of 15 W,1 s-pulse duration,1 s-interval,and an energy of radiation of 800~1 200 J.Curative outcomes were evaluated based on the Visual Analog Scale(VAS) criteria. Results The operation time was 15~60 min(mean,30 min).The pain provocation was observed in 32 patients.Follow-up examinations were conducted in the 36 patients for 6~36 months(mean,11 months).The postoperative VAS scores were improved by ≥ 3 points in 18 patients and ≥ 2 points in 14 patients.Results revealed that 32 patients(88.9%) reported a good response and 4(11.1%) reported no response. Conclusions Percutaneous laser disc decompression is a safe,effective,and minimally invasive procedure that can be used for patients with discogenic low back pain.

Objective To investigate the impact of functional enhancement of efflux pump system and reduced permeability of outer membrane on high-level multiple resistant Neisseria gonorrhoeae.Methods Several high-level multiple resistant isolates with erythromycin MIC=128.0 mg/L,accompanied by concurrent resistance to several antimicrobial agents,were selected.13 bp inverted sequence positioned within the mtrR promoter region were amplified by PCR and directly sequenced to detect the possible gene change.The outer membrane proteins of the strains were extracted to analyze the constitutive profiles by SDS-PAGE.Results There were no gene mutations in 5 sensitive strains.All the 3 high-level multiple resistant strains contained the same mutation and exhibited a single A/T base pair deletion in 13 bp inverted sequence positioned within the mtrR promoter region.Meanwhile porin protein 31 ku deficiency was found in all the 3 resistant strains.Conclusion The functional enhancement of efflux pump system induced by a single A/T base pair deletion in 13 bp inverted sequence positioned within the mtrR promoter region and the decreased cell envelope permeability induced by the absence of porin protein may have some effect on mediating high-level multiple resistance in Neisseria gonorrhoeae.

Objective To guide bracing treatment for adolescent idiopathic scoliosis (AIS). Methods A total of 68 AIS patients with apex vertebrae (AV) under T6 had received the improved Cheneau bracing treatment between March 2008 and June 2010. All patients were divided into two groups. There were 16males and 35 females, with a mean age of 13.6 years (range, 10.6-17.2) in the intervention group. The mean Cobb angle was 29.5° (range, 20°-38°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the group;while there were 6 males and 11 females, with a mean of 13.2 years (range, 10.8-16.8) in the control group.The mean Cobb angle was 28.7° (range, 20°-37°); Risser sign was 2-4; Vertebralrotation degree was 0-2 in the control group. All patients in control group were informed standardized bracing treatment method. But we gave patients in intervention group two copies of "The Form of Guiding Bracing Treatment" treatment of patients with AIS, and informed that they carried out the bracing treatment according requirement of the form.Cobb angle was measured before the treatment and at 6th, 12th, 18th month after treatment. Results Sixtyfive cases were followed up for 18-27 months. However, one female in control group and two females in intervention group were lost during follow-up. Coefficient and intraclass correlation coefficient of form were both over 0.60. The acceptance rate of the table was 97.54%(199/204), qualified rate was 100.00%( 199/199), and with good content validity. The mean Cobb angle decreased gradually from 28.71° to 25.76° in control group and from 29.47° to 21.59° in intervention group. Four cases in control group and 34 cases in intervention group had reduced more than 5° at 18 months after treatment. There was significant difference regarding Cobb angle between two group. Conclusion The form of guiding bracing treatment has good reliability and validity and can guide bracing treatment of AIS correctly and effectively.

Objective To observe the anaesthetic effect of sulfentanil combined with bupivacaine for subarachnoid block on cesarean section patients and the influence on the patient and fetus.Methods Eighty patients who were scheduled for elective cesarean section under subarachnoid block,were distributed into two groups:bupivacaine with no sulfenlanil(group B)and bupivacaine with sulfentanil(group BS).Detected SBP,DBP,MAP,HR,SpO2 before and after anesthesia.The time of drug onset,motor recovery and pain recovery were recorded,the effect of muscle relaxation was evaluated,and the drag reaction,neonatal Apgar score and anesthesia complication were recorded.Results There was no significant difference in the time of drug onset and motor recovery,muscle relaxation,neonatal Apgar score between the two groups.MAP was lower after 3-10 min of anesthesia than before anesthesia,but there was no significant difference after 30-120 min of anesthesia in the two groups.The rate of drag reaction was 27.5% in group B,but no case in group BS.The time of pain recovery was longer in group BS than that in group B(P＜0.01).The rate of temporary itch of skin after operation was 17.5% in group BS.Conclusion The addition of sulfentanil to hyperbaric bupivacaine provides adequate anesthesia for cesarean section and good postoperative analgesia.
