Objective To search for the reasons of high positive rate of amotile bacteria and the diagnosis of septicemia in new-born Methods The blood was drawn from the different site of the new-born with septicemia and carricd out blood culture. The drug sensitivity test had been done by the method of paper stripdiffusion. The plasmids of bacteria were extracted rapidly by medified Birnboim method and the plasmid analyss was carried out. The plasmids's DNA of 35 epidemic strain was cut off by both restriction enzyme of Hind Ⅲ and EcoR Ⅰ. The outer membrane protein (OMP) was determined by SDS-polyacrylamide gel electrophoresis.Results There are 51 patients with positive blood culture amotile bacterium,of them, pollution; 35 cases (68．6%), septicemia: only 16 cases (31．4%),54．8% (57/104) strains bacteria have drug resistance to more of 12 drugs. 87．3% (165/189) strains bacteria have plasmids. They are cut off as 6 DNA fragments (1．9,2,4,5, 8．5 and 18Kb) by Hind Ⅲ restrietion enzyme. and as 5 DNA fragments (2,2．6,3．2, 6．3 and 22 Kb) by EcoR Ⅰrestrietion enzyme, it is showed that they come from a same clone. The epidemic strain include 10 slips OMP, but non-epidemic strain have 11 slip OMP, increase a 25Kd belt. The amotile bacteria with above-mentioned plasmid spectrum, restriction enzyme spectrum and OMP spectrum are only seen in the air, therapeutic dish and syringe needle.Conclusion The pollution is an important reason of amotile bactorium high positiye rate in new-born.Diagnosing septicemia should depend on bacteria culture, plasmid analysis restriction enzyme analysis of plasmid DNA, oMP determination and combining medical history and clinical manifestation.

OBJECTIVETo evaluate the erectile and ejaculatory function of sacral tumor patients after sacral nerve root resection and investigate the relationship of erectile and ejaculatory dysfunction (EED) with the level of sacral nerve injury.

METHODSThis retrospective study included 47 male patients aged 16 to 63 (32.6 +/- 6.8) years treated by sacral tumor resection between January 2008 and August 2013. According to the levels of the sacral nerve roots spared in surgery, the patients were divided into four groups: bilateral S1-S3 (n=16), unilateral S1-S3 (n=21), unilateral S1-S2 (n=6), and unilateral S1 (n=4). The patients were followed up for 12 to 41 (27.2 +/- 10.9) months by questionnaire investigation, clinic review, and telephone calls about their erectile and ejaculatory function at 3, 6 and 12 months after surgery and in August 2013.

RESULTSIn the bilateral S1-S3 group, the incidence rates of EED were 31.25% (5/16), 25% (4/16), and 12.5% (2/16) at 3, 6, and 12 months respectively after surgery, with recovery of erectile and ejaculatory function in August 2013. The incidence rates of EED in the unilateral S1-S3 group were 85.71% (18/21), 71.43% (15/21), 52.38% (11/21), and 42.86% (9/21) at 3, 6 and 12 months and in August 2013, respectively; those in the unilateral S1-S2 group were 100% (6/6), 83.33% (5/6), 83.33% (5/6), and 66.67% (4/6) at the four time points; and those in the unilateral S1 group were all 100% (4/4). No statistically significant differences were found in the incidence rate of EED among the patients of different ages or tumor types (P > 0.05).

CONCLUSIONThe incidence of postoperative EED in male patients treated by sacral tumor resection is closely related to the mode of operation. Sparing the S3 nerve root at least unilaterally in sacral tumor resection is essential for protecting the erectile and ejaculatory function of the patient.

OBJECTIVETo establish a new method for simultaneous determination of shanzhiside methyl ester, chlorogenic acid, 8-O-acetyl shanzhiside methylester, forsythiaside B, rutin, acteoside and galuteolin in Lamiophlomis rotata.

METHODSeparation was performed on a Welchrom-C18 chromatographic column with acetonitrile-0.1% orthophosphoric acid as mobile phasewith gradient elution. The flow rate was 1.0 mL x min(-1). The column temperature was 30 degrees C, and the detection wavelength was set at 238 nm, 330 nm and 350 nm.

RESULTThe seven compounds were well separated with good linear correlations. The mean recoveries of seven compounds were 96.47%-102.2% (RSD 0.70%-2.2%).

CONCLUSIONThere were good correlations among the seven compounds in the samples of aerial parts. The mean sum of shanzhiside methyl ester and 8-O-acetyl shanzhiside methylester in samples of aerial parts is 1.44%. The aerial parts have more kinds of composition and with higher content than that of underground parts in L. rotata, which was reasonable for the resonable use of the aerial part as medicinal part. The method was simple, repeatable and stable, which could be used for identification and quality evaluation of L. rotata.

OBJECTIVETo explore clinical outcomes and advantages of anterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal tuberculosis.

METHODSFrom February 2010 to February 2014, totally 82 patients with lumbar spinal tuberculosis were treated by posterior individual fixation with small-incision focus debridement,including 50 males and 32 females with an average of 50.5 years old. All patients were divided into two groups according to different procedures. Forty-nine patients in group A were treated with anterior small-incision focus debridement with posterior internal fixation through muscle spa ring at stage I ; and 33 patients in group B were treated with focus debridement with posterior internal fixation by extraperitoneal approach at stage I . Postoperative mechanical ventilation time, preoperative and postoperative Cobb angle, visual analogue scale (VAS), erythrocyte sedimentation rate (ESR) and Frankel grading were observed and compared. Postoperative complications, stability of internal fixation and bone union were compared.

RESULTSAll patients were followed-up from 15 to 36 months with an average of 23.7 months. Psoas abscess of three patients in group A and 1 patient in group B on the opposite side increased and were healed by the secondary apocenosis. The other 78 cases were healed at stage I, and no sinus tract formation, incisional hernia, leakage of cerebrospinal and occurrence of spinal tuberculosis were occurred. Fracture healing time ranged from 3 to 7 months with an average of 4.6 months. Postoperative mechanical ventilation time and VAS score in group A was better than group B. There were no statistical differences in Cobb angle, ESR and Frankel grading at the final following-up between two groups.

CONCLUSIONAnterior small-incision focus debridement with posterior internal fixation through muscle spa ring in treating patients with lumbar spinal according to degree of damage is a safe and effective method.

Objective To establish CFPAC-1 cell lines deficient in CDC25B2 by recombinant lentivirus, and to investigate the role of this gene. Methods After CFPAC-1 cells were transduced with recombinant lentivirus producing CDC25B2 siRNA, stably transduced cells with green fluorescent protein were selected by flow cytometer. The mRNA and protein expression of CDC25B2 was examined by RT-PCR and Western blot analysis. The effect of the lentivirus on the cell proliferation, cell cycle, clone-forming, migration and invasion ability was analyzed by MTr method, flow cytometer, plate clone-forming assay and Transwell chamber method respectively. Results CDC25B2 siRNA knocked down CDC25B2 expression in CFPAC-1 cells significantly. The silencing efficiency of siRNA transduction by recombinant lentivirns was very high. Proliferation, cloneforming, migration and invasion ability of human pancreatic cancer cell line CFPAC-I were significantly in-creased, while cell cycle was not affected. Conclusion CDC25 B2 plays an important role in cell proliferation, clone-forming, migration and invasion of pancreatic cancer. This research provides experimental evidences for targeting CDC25B2 in gene therapy against pancreatic cancer.
