Objective:To study the efficacy comparison between the antibacterial catheter and common central venous catheter in ICU patients.Methods: The 110 ICU patients with central venous catheter were randomized into the control group (common central venous catheter)and the observation group (antibacterial catheter), 55 patients per group. The success rate of catheter, the averange catheter days, complications, and the incidence of catheter-related infection (CRI)and pathogen distribution in the two groups were observed and compared.Results: Compared with the control group, the success rate of catheter was significantly increased(100.0% vs 81.8%,x2=11.00,P<0.05), the averange catheter days were obviously reduced(12.5±3.0 vs 13.5±3.0,t=3.49,P<0.05)days, the incidences of complications (red and swelling in puncture site(3.6% vs 27.3%,x2=11.76,P<0.05), fluid in puncutre site (3.6% vs 21.8%,x2=8.18,P<0.05), catheter herniation(1.8% vs 20.0%,x2=9.35,P<0.05)were significantly decreased in the observation group with statistical difference (P<0.05). Conclusion: The antibacterial catheter can significantly reduce the incidence of CRI for ICU patients and improve the security of central venous catheter.

Objective To evaluate the diagnosis and therapy of intestinal obstruction caused by multiple jejunal diverticula.Methods Clinical data of intestinal obstruction caused by multiple jejunal diverticula in 18 cases admitted from Jan 2001 to Aug 2012 were analyzed retrospectively.Results All patients experienced the symptoms of abdominal pain and abdominal distension,5 cases experienced nausea and vomit,2 cases had a fever.Plain abdominal X-ray series demonstrated distension of small bowel and multiple air-fluid levels,5 cases with anemia,the average value of hemoglobin was (9.5 ± 1.0) g/L,B-ultrasonography revealed bowel dilatation in 7 out of 15 cases,9 cases underwent abdominal computed tomography and all had positive sign of small bowel distension and multiple air-fluid levels,mesenteric volvulus was suspected in 1 case.All patients underwent laparotomy,the diagnosis of multiple jejunal diverticula were confirmed clinically and by the pathology.In a follow-up ranging from 2 to 25 months,1 case died,the others were symptoms free.Conclusions Multiple jejunal diverticula was a less common disorder,occurring mainly in old man,with a low preoperative definite diagnosis.Resection of affected intestinal segment with primary anastomosis results in satisfactory prognosis.

Hypericin, used as a medicinal heifo since ancient times, is a natural photosensitizer derived from the plant Hypericum perforantum. Hypericin would produce peroxides to induce apoptosis and inhibit the growth of oncocytes. Meanwhile, hypericin has a specific affinity with tumor pathology organization (underlying accumulation in pathology organization) which has been widely used in optical diagnosis. The present review gives a comprehensive summary of the anticancer effect based on photodynamic therapy, and photodynamic diagnosis of hypericin optical properties, with the purpose of making full use of the hypericin natural resources, and providing a basis for research and development of hypericin derivatives. © 2006 Editorial office of Foreign Medical Sciences.

Objective To study the prevalence and morphological features of myocardial bridge(MB) on dual-source computed tomographic coronary angiography(DSCTCA),and to determine the relationship between MB and the neighboring coronary atherosclerosis.Methods Totally 835 consecutive patients with suspected coronary disease or for physical examination underwent DSCTCA for the presence of MB.The number,length,and depth of MB were observed and evaluated.All cases of MB were divided into two groups according the presence or absence of atherosclerosis in the coronary artery 2 cm neighboring to MB.The patients' age as well as the length and depth of MB were compared between two groups.Results One hundred and ninety-five MB segments were identified in 182 of 835(21.8%) patients.Of 195 segments,183 located in left anterior descending coronary artery(LAD)(93.8%).The mean length of MB segments was(19.5?8.2) mm,and the mean depth(1.5?0.8) mm.No evidence of atherosclerosis was found in the mural coronary artery.In a 2-cm-long segment immediately proximal or distal to MB,atherosclerotic plaques were found in 75(38.5%),including 66 proximal segments(33.8%) and 9 distal segments(4.6%).The patients' age in the group with atherosclerosis was significantly older than that in the group without atherosclerosis(P

Objective To investigate the value of multivoxel proton magnetic resonance spectroscopy(1H-MRS) in contusion and laceration area of mild-to-moderate traumatic brain injury(TBI) in adults.Methods Twenty-eight TBI patients definitely diagnosed were recruited in this study,including 16 moderate TBI whose Glasgow coma scores were in 9-12 and 12 mild TBI whose Glasgow coma scores were in 13-15.The spectrum for NAA,Cho,Cr and other metabolite peaks in contusion and laceration area were measured and NAA/Cr,NAA/Cho,Cho/Cr ratios were calculated for each voxel.Results In multivoxel 1H-MRS for the lesion areas,the ratios of NAA/Cr,NAA/Cho and Cho/Cr changed significantly compared with those of 16 normal controls(P0.05).Conclusion Multivoxel 1H-MRS may have an important clinical value in detecting and assessing early mild-to-moderate brain trauma.NAA/Cr ratio of the injured region can reflect the severity of cerebral injury.

Hemodynamic monitoring is an essential part in the care of children with congenital heart disease during perioperative period to guide clinical management.Currently,there are several methods available for hemodynamic monitoring.The invasive methods include the Fick method,thermodilution method,using the Swan-Ganz catheter and the pulse contour method.The noninvasive methods include partial carbon dioxide resorption,impedance method.In this paper,the principle,advantages and disadvantages of these monitoring methods in children undergoing cardiopulmonary bypass surgery were reviewed.

BACKGROUND:Bryan cervical disc replacement and anterior cervical discectomy and fusion have a dispute in the treatment of cervical spondylosis.
OBJECTIVE:To evaluate the clinical effects of Bryan cervical disc replacement and anterior cervical discectomy and fusion by meta-analysis, thereby providing clinical evidence for treatment strategy of cervical spondylosis.
METHODS:The authors searched Medline, PubMed, EMBASE, OVID, CBM, CNKI and also searched manual y seven relevant Chinese orthopedic journals for articles pertinent to clinical research of Bryan cervical disc replacement and anterior cervical discectomy and fusion. Extracted data included the range of motion of the cervical spine, visual analog scale score, neck disability index, the Japanese Orthopaedic Association score. Meta-analysis and forest plots were conducted with RevMan4.2.2 Software.
RESULTS AND CONCLUSION:There are eight articles in the meta-analysis, including 883 patients (430 patients receiving Bryan cervical disc replacement, and 453 patients receiving anterior cervical discectomy and fusion). Meta-analysis did detect statistical y significant differences in the range of motion of the cervical spine at 3 months and 24 months postoperatively between the two groups, but did not detect statistical y significant differences in visual analog scale score, neck disability index, the Japanese Orthopaedic Association score between the two groups. These findings indicate that Bryan cervical disc replacement is superior to anterior cervical discectomy and fusion in the range of motion of the cervical spine. However, the current literature offers no evidence to support superiority of the Bryan cervical disc replacement over the anterior cervical discectomy and fusion.

[Objective] To investigate the relationship between serum leptin level in chronic renal failure (CRF) and Qi or yang deficiency syndrome of spleen and kidney. [Methods] Thirty-eight cases of CRF and 16 healthy subjects as control were enrolled in this study. The CRF patients were classified as Qi /yang deficiency syndrome of spleen and kidney (pattern 1) and non-Qi/yang-deficiency syndrome of spleen and kidney (pattern 2). Serum leptin level was detected by enzyme-linked immunosorbent assay and nutrient parameters such as serum albumin (ALB), C-reation protein (CRP) and pre;ilbumin (preAlb) levels were also observed. The relationship of leptin level and nutrient parameters with Qi or yang deficiency syndrome of spleen and kidney was observed. [Results] The serum leptin level of pattern 1 was higher than that of pattern 2 ( P 0.05) . [ Conclusion ] Serum leptin may be the partial material base of Qi or yang deficiency syndrome of spleen and kidney and this is worthy doing further research. The uncertain relationship between nutrient parameters and Qi or yang deficiency syndrome of spleen and kidney may be due to the increase of type Ⅱ error which results from the small sample size.

Objective To explore a simple and safe method for preservation of the sputum aspirator nozzle. Methods Using self-controlled method, the traditional method was to place the nozzle in the glass bottle of disinfectant liquid, the modified method was to fix a sputum tube to a suitable location of the sputum aspirator or bedside with the joint free, after sputum aspiration,the nozzle was connected to the joint. One patient used the same sputum aspirator. The two methods of preservation were alternated every 24 hours. The slippage times of the nozzle were compared, and samples from glass nozzle and joints of disinfectant liquid bottles/spu-tuna tube joints were underwent bacterial culture. Results Significant difference existed in slippage times of the nozzle, the positive rate of bacteria colony in the.glass nozzle and disinfectant liquid bottles/sputum tube joints between the two methods. Conclusions Using sputum aspiration tubes to fix the nozzle of aputum aspi-rator is better than the traditional method of putting the nozzle into the glass bottle of disinfectant liquid,this method proves to be easy, safe,portable and economical and is worthy of clinical application.
