Objective To investigate the clinical effects of the modified Kock method of bladder re- construction with ileum,and to provide the objective basis for wide application of this technique.Methods A total of 51 patients with bladder cancer(T_2N_0M_0 stage tumor in 37 cases,T_3N_0M_0 stage tumor in 14; and pathologic gradeⅡ-Ⅲin all)were included.After radical cystectomy,modified Kock reconstruction of bladder with ileum was performed in them.The procedure consisted of preparing the segment of the ileum for reconstruction of the reservoir,anastomosing the low part of the neobladder with the urethra and regaining the original urinary conduit.Results The mean operative time was 6.5h(range,5.5-8.5h);mean in- traoperative blood loss was 650ml(range,300-1200ml),with blood transfusion in 31 cases.Perioperative complications included stress ulcer in 6 cases and urinary leakage in 1.The other 44 cases had no severe complications.Four cases died of cancer metastasis at 6-18 months after operation.During a follow-up of 8 -32 months,the other 47 cases recovered well and have been alive till now.Two cases had ureteral urine reflux with no impairment of renal function.The daytime urinary continent rate was 100%;and nocturnal uri- nary incontinence occurred in 6 cases.Conclusions The modified Koek reconstruction of bladder with il- eum can improve the patients'quality of life with fewer complications,therefore is a better treatment choice for infiltrative bladder cancer after radical eystectomy.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

Objective To establish a method for culture of rat pulmonary capillary pericytes.Methods Six male Sprague-Dawley rats,aged 6-7 weeks,weighing 200-220 g,were anesthetized and the chest was opened.The pulmonary capillary was isolated by type Ⅰ collagenase digestion and micropore filtration and cultured in highglucose DMEM/F12 1∶1 containing 10％ fetal bovine serum and 0.5％ mixture of penicillin and streptomycin.The morphology and growth of cells were observed with inverted phase contrast microscope.The positive cells of αsmooth muscle actin (α-SMA),desmin,neuron-glial antigen 2 (NG2),cluster of differentiation 31 (CD31) were counted by immunofluorescence.The percentage of positive cells was calculated.Results The microscopic examination showed cells of shuttle shape or star shape,mononuclear cells,binuclear cells occasionally,oval nucleus,rich cell plasma,growth in the shape of vortex or fence,and no contact inhibition.The percentage of positive cells ofα-SMA,desmin,NG2,and CD31 was (99.0± 1.2)％,(96.0±2.1)％,(99.0±0.7)％ and0,respectively.Conclusion The culture method for rat pulmonary capillary pericytes is successfully established.

OBJECTIVETo investigate the expression of Shh and its receptors Ptc1 and Ptc2 mRNA in the cap stage of mouse molar and discuss its role in early tooth morphogenesis.

METHODSThe embryonic mouse heads of early tooth development (E10.5 - E15.5) were obtained and 5 micro m serial sections were made. Immunohistochemical staining of PCNA was carried out by SP method. The expression pattern of Shh, Ptc1, and Ptc2 mRNA was analysed by in situ hybridization.

RESULTSE14.5, outer dental epithelium, inner dental epithelium, stellate reticulum and underlying dental mesenchyme were PCNA positive. Most of the enamel knot cells were PCNA negative. A few of the enamel knot cells were PCNA positive. Shh, Ptc1, and Ptc2 mRNA were strongly expressed in outer dental epithelium, inner dental epithelium, stellate reticulum and the enamel knot.

CONCLUSIONIn the cap stage, Shh as a paracrine and autocrine signaling molecule might stimulate epithelium and mesenchyme proliferation.

OBJECTIVETo analyze retrospectively the clinical outcome of surgical management for upper cervical spine injury caused by trauma.

METHODSFrom January 2005 to March 2007, 16 patients with injury of upper cervical spine were treated by different management. There were 11 males and 5 females with an average age of 44 years ranging from 24 to 75. Of all, 5 cases were the odontoid fracture, 3 were atlas fracture, 5 were Hangman's fracture, 3 were atlanto-axial dislocation. MR imaging of cervical spine showed cervical cord compression and changes of T2 high signal in 5 cases. According to the injury mechanism, the imageological appearance, fracture classification, the methods of treatment were selected.

RESULTSSeven patients received non-operative treatment and nine patients underwent operation. Sixteen patients were followed up for 7 to 34 months (means 10.5 months). All fractures were healing or bone graft fusion and no internal fixation was lossing. There were no injuries of vertebral artery, nerve root or spinal cord.

CONCLUSIONCT and MRI are required in the course of diagnosis for the traumatic injury of upper cervical spine. The optimal modus operandi should be choose to retain upper cervical spine, meanwhile, can reserve the cervical movement.

OBJECTIVETo evaluate the effect of absolute alcohol treatment for renal cyst with percutaneous puncture and catheterization.

METHODSThis report presented 64 cases of renal cysts, 34 cases were treated with percutaneous puncture (A group) and 30 cases with percutaneous catheterization (B group). According to the size, the cysts were divided into 2 groups, more than 6 cm in diameter and less than 6 cm in diameter.

RESULTSAll the patients were followed up for 3 - 12 months by CT or B ultrasonography. Striking difference of the therapeutic results were existed when cystS were more than 6 cm in diameter.

CONCLUSIONPercutaneous catheterization is applicable to the sclerosing treatment of renal cyst whose diameter is more than 6 cm.

OBJECTIVETo investigate the apoptosis effect induced by D-limonene on BGC-823 gastric cancer cells.

METHODSThe expression of p53, bc1-2 in BGC-823 cells and qualitative, quantitative index of cell apoptosis were detected with MTT, electron microscopy, flow cytometry and immunohistochemical method.

RESULTSD-limonene could induce the formation of apoptotic bodies in a dose- and time-dependent manner. The expression of bcl-2 protein decreased and p53 protein increased in BGC-823 cells treated with D-limonene, compared with the control cells.

CONCLUSIOND-limonene exerts its cytotoxic effect on BGC-823 gastric cancer cells by inducing apoptosis.

AIMTo prepare long-circulating solid lipid nanoparticles containing paclitaxel with stearic acid, and investigate the in vitro and in vivo characterization of nanoparticles.

METHODSThe method of "emulsion evaporation-solidification at low temperature" was used to prepare the stearic acid solid lipid nanoparticles containing paclitaxel. Its morphology was examined by transmission electron microscope. The HPLC method for determination of paclitaxel in nanoparticles or serum samples was established. The release of paclitaxel in vitro and the pharmacokinetics after i.v. bolus injection to mice were studied.

RESULTSThe mean diameter of Brij78-SLN and F68-SLN is (103.5 +/- 29.2) nm and (220 +/- 98) nm, respectively. The nanoparticles release paclitaxel slowly and linearly, within 24 h, Brij78-SLN and F68-SLN release 8% and 20% of total drug, respectively. Long-circulation nanoparticles was found to stay in the blood circulation, with T 1/2 beta 10.1 h of F68-SLN, and T 1/2 beta 4.88 h of Brij78-SLN more than one commercialized paclitaxel injection, T 1/2 beta 1.3 h.

CONCLUSIONStearic acid might be a new drug carrier material in the future.
