Objective To detection the urine of bacteria hyphae and intracellular bacterial communities in patients with indwelling urinary catheter and discuss intracellular bacterial comnmunities in the pathogenesis of catheter-related urinary tract infection.Methods From May 2014 to February 2016,95 cases with D-J stent indwelling were enrolled in this study,including 38 male patients and 57 female patients.The mean age was (43 ±21)years old,ranging from 25 to 83 years old.We recorded those patient g clinical symptoms,middle urine culture results.If the middle urine culture was positive,further pathology test and scanning electron microscopy for bacteria hyphae and intracellular bacterial communities would be considered.Results The middle urine culture showed positive in 21 cases (22％,21/95);The classification of bacteria included E.coli in 11 cases,dung enterococcus in 2 cases,klebsiella pneumonia in 4 cases,pseudomonas aeruginosa in 3 cases,epidermis staphylococcus aureus in 1 case.Among those 21 patients,9 cases had the symptoms of fever and shiver.Urine pathology testing found hyphae in 6 cases (6％,6/95).all others were E.coli infection.For scanning electron microscope,6 cases were found rodshaped bacteria and hyphae.3 cases were found intracellular bacterial communities.Conclusions The presence of intracellular bacterial communities made urothelial itself the source of endogenous bacteria of urinary tract infection.Catheter-related urinary tract infections in patients with recurrence maybe basically homology bacteria.

Preeclampsia(PE) is a unique disease to pregnancy women,and women who had a history of preeclampsia significantly increased the risk of cardiovascular disease.Preeclampsia etiology and pathogenesis is not clear yet,it may have common pathophysiology with cardiovascular disease(CVD),such as oxidative stress,endothelial injury,insulin resistance,lipid metabolic disorder and so on.The article reviewed the relationship between preeclampsia and long-term cardiovascular disease among women,especially discussed the disease such as coronary heart disease,hypertension and stroke,to find the association and to explore the potential risk management options for these high-risk women.To block,intervene,and prevent cardiovascular disease starting with preeclampsia,it is of significance to the cardiovascular health of over 300 million women worldwide.

In April of 2008 water samples were collected from four different rivers,which were Wuchao gang River,Henggang River,Chaoyang River and Caoyanghuanbang River.During the sampling the physi-cal and chemical parameters were measured.The abundance and the diversity of the bacteria of these four rivers were studied.The results showed that the population level increased in the more severely polluted river while the bacterial diversity decreased;the bacterial community structure was also affected by the dif-ferent ecological conditions of each sampling spot.The bacterial composition and abundance was closely related to the water quality in the river.

Objective To improve the level of early detection and treatment of pyonephrosis. Methods This study included 41 cases(17 men and 24 women;mean age,49 years)of pyonephrosis.A variety of examinations,including urinary analysis,blood analysis,kidney nuclear medicine scan,ultrasonog- raphy,intravenous urography(IVU),and CT were used for the early diagnosis of pyonephrosis.Pereutaneous nephrostomy(PCN)drainage was done for the interim management of pyonephrosis,then phase 2 operation was performed in 28 cases.The double-J tube was placed in ureter by ureteroscope for drainage,and then phase 2 operation was done in 2 cases.Emergency operation was done in 10 cases.The remaining 1 case un- derwent ESWL after anti-infective therapy.Results Definite diagnosis of pyonephrosis before operation was made by invasive examinations in 31 cases(75.6%),and by percutaneous drainage in 4 cases;the other 6 cases were detected during operation.Only 6 cases(14.6%)underwent nephrectomy;the other 35 cases (85.4%)underwent kidney-sparing operation.Follow-up of 3 months to 9 years was available in 37 cases. No nephrectomy was needed in 33 cases with spared kidney.Serum creatinine was normal in the 4 cases un- dergoing nephrectomy.Conclusions The key to the treatment of pyonephrosis by kidney-sparing surgery is early diagnosis,timely drainage and relief of obstruction.Ultrasonography plays an important role in the early diagnosis of pyonephrosis,and CT has a high sensibility in the diagnosis.Pereutaneons nephrolithotomy (PCNL)secondary to drainage through pereutaneous nephrostomy was beneficial to the patients with kidney stones or upper ureter stones.

BACKGROUND: The restenosis occurs up to 20%-30% following metal coronary stent implantation. Under the support of the 863 program, the feasibility to treat coronary artery stenosis using a novel drug-eluting stent (DES) has been investigated to reduce restenosis. OBJECTIVE: A drug-eluting stent (rapamycin as drug mode) was implanted into porcine models of coronary stenosis. The safety and efficacy of the drug-eluting stent were observed and compared with bare-metal stent. DESIGN, TIME AND SETTING: A randomized controlled animal experiment was performed in the Fu Wai Hospital for Cardiovascular Disease between November 2003 and April 2004. MATERIALS: A novel bioinspired phospholipid copolymer was synthesized by free radical polymerization of stearyl methacrylate, β-hydroxypropyl methacrylateand 3-(trimethoxysilyl) propylmethacrylate. METHODS: Twenty-one pigs were randomly divided into 3 groups: bare-mental stent, drug-eluting stent, and polymer-coated stent. The treated stents pre-loaded onto a delivery system through the use of crimping instrument were implanted into pig's coronary artery, with 2 stents per pig. MAIN OUTCOME MEASURES: Determination of luminal diameter, luminal area, mean intimal thickness on and between the stents, neointimal area, percentage of luminal area restenosis, and damage index using an image analysis instrument. RESULTS: At 28 days after implantation, there was significant difference in mean intimal thickness on and between the stents, as well as neointimal area, between the DES and bare-metal stent groups (P < 0.05). The neointimal area was reduced by 44.87% in the DES group compared with the bare-metal stent group. No significant difference in percentage of luminal area restenosis was found between the DES and bare-metal stent groups, but P value equaled to 0.053, which was close to 0.05. In addition, no restenosis was found in the DES group. CONCLUSION: Rapamycin DES can markedly resist intravascular intimal hyperplasia and restenosis following stenting.

BACKGROUNDAtrioventricular nodal reentrant tachycardia (AVNRT) is one of the most common paroxysmal supraventricular tachyarrhythmias. The aim of the study was to prospectively compare the characteristics of radiofrequency catheter ablation of AVNRT guided by a magnetic navigation system with the conventional procedure.

METHODSPatients with AVNRT diagnosed by electrophysiological tests were randomized into two groups. In the conventional technique group (CMT), a common 4-mm-tip quadrapolar temperature-controlled ablation catheter was used. In the magnetic navigation system guidance group (MNS), a magnetic 4-mm-tip quadrapolar temperature-controlled ablation catheter was used. The following parameters were collected and compared between the two groups: ablation procedure time, patient fluoroscopy time, operator fluoroscopy time, energy delivery numbers, maximal energy per deployment, success rate, complication rate and operative cost.

RESULTSForty patients were enrolled and randomized into CMT and MNS groups. The age, gender, tachycardia history and basic cardiovascular diseases of the two groups were comparable (P > 0.05). All procedures were conducted successfully without complications. No tachycardia recurred during the follow-up period of (9.3 ± 2.6) months. In the MNS group, the patient and operator fluoroscopy times ((11.5 ± 4.3) min, (4.2 ± 1.5) min), energy delivery numbers (3.2 ± 0.9), and maximal energy per deployment ((16.9 ± 3.4) W) were shorter or lower than those of the CMT group ((14.3 ± 6.2) min, (13.6 ± 3.5) min, 6.3 ± 2.1, (23.7 ± 1.3) W, respectively) (P < 0.05). But the operative cost for the MNS group was higher than that of the CMT group (P < 0.01).

CONCLUSIONMagnetic navigation system guided radiofrequency catheter ablation of AVNRT has the advantages of shorter fluoroscopy time and lower energy delivery numbers and maximal energy per deployment compared to the present conventional ablation technique.

OBJECTIVETo investigate the feasibility of utilizing self-designed score system for lower lumbar vertebral burst fractures to select surgical approach.

METHODSFrom January 2006 to December 2011, the clinical data of 56 patients with lower lumbar vertebra burst fractures who underwent surgical treatment were retrospectively analyzed. There were 42 males and 14 females with an average age of 43.1 years old (ranged, 19 to 65). Causes of injury included falling down (40 cases), traffic accidents (12 cases), and crashing injury by heavy objects(4 cases). Injury site was L3 in 37 cases, L4 in 16 cases, and L5 in 3 cases. According to the AO classification, 17 cases were type A3.1, 14 cases were type A3.2, 25 cases were type A3.3. According to Frankel grade of nerous function, 2 cases were grade B, 5 cases were grade C, 9 cases were grade D and 40 cases were grade E. Surgical methods and approaches were chosen based on the comprehensive evaluation of AO classification, condition of posterior column injury and spinal canal encroachment. Surgical methods and approaches included trans-vertebra fixation (15 cases), intra-vertebra pedicle screw fixation (21 cases), combination of anterior and posterior approaches (11 cases), one-stage posterior approaches (9 cases). Cobb angles, restorations of the affected vertebral anterior border height, and conditions of spinal canal encroachment were compared before and after surgery. Conditions of bone graft fusion and internal fixation (if bending, loosening or breakage existed) were observed. Spinal cord functions were assessed according to Frankel grade. Localized pain and working status of patients were also assessed at the last follow-up.

RESULTSNo incision infection was found and no spinal nerve symptoms improved in all of 56 patients. All patients were followed up for 12 to 60 months with a mean of 28.5 months, without internal fixation loosening or breakage. There was significant differences in Cobb angle, vertebral anterior border height and recovery of spinal canal encroachment between preoperative and postoperative instantly (P < 0.05), however, there was no significant difference between postoperative instantly and final follow-up (P > 0.05). Thirteen cases obtained fusion by trans-vertebra fixation, 20 cases obtained fusion by intra-vertebra fixation, and 20 cases were treated by the combination of anterior and posterior approaches or one-stage posterior approaches all of patients obtained fusion. Spinal nervous function recovered I to II grade, 1 case was grade C, 3 cases were grade D, 52 cases were grade E. Localized pain was assessed as P1 in 52 cases, P2 in 3 cases, and P3 in 1 case. Working status was classified into W1 in 12 cases, W2 in 39 cases, and W3 in 5 cases.

CONCLUSIONThe lower lumbar vertebra and thoracolumbar junction exhibit different injury characteristics due to variations in anatomy and biomechanics. A comprehensive score of the AO classification, posterior column injury and degree of spinal canal encroachment will guide the selection of surgical method and approach for the treatment of lower lumbar vertebra burst fractures.
