OBJECTIVE To study the clinical effect of preventing and treating sterile phlebitis(abacterial phlebitis,SP) by infrared irradiation after peripherally inserted central catheterization(PICC).METHODS Totally 122 inpatients from the Zhejiang Provincial People′s Hospital were divided into two groups randomly,the control group and the experimental group.The control group was only treated with usual care after PICC,while the experimental group with both infrared irradiation and usual care.The incidence rate of SP and its correlation factor were compared between the two groups.RESULTS None in the experimental group got SP.Nevertheless,the control group got a 21.9%incidence rate.The development of SP mostly own to impassable intubation or repeating intubation.CONCLUSIONS For those patients with impassable intubation or repeating intubation during PICC operation,infrared irradiation shows greatly helpful and can obviously prevent the SP and diminish patients′ fee.

Objective To investigate the protective effects of low-molecular heparin and urokinase on glomerular inflammation. Methods Forty 3-month-old female Wistar rats were randomly divided into five groups with 8 rats in each group: normal control (NC) group; lipopolysaccharide (LPS) group; LPS and tranexamic acid (LT) group; LPS, tranexamic acid and low-molecular heparin (LTH) group; and LPS, tranexamic acid and urokinase (LTU) group. Fibrin deposition and CD11b positive cells were identified by immunohistochemical staining. Western blotting was used to determine the ICAM-1 expression. Results No fibrin depositions and CD11b positive cells were found in glomeruli of rats in NC group. Compared with NC group, fibrin deposit (9.1%?1.6%), CD11b positive cell (11.2?2.1) and ICAM-1 expressions (0.23?0.09) were significantly increased in L group (P0.05). Conclusion Both low-molecular heparin and urokinase can effectively decrease fibrin deposits and alleviate inflammation.

Objective To compare the degree of atherosclerosis in middle-aged versus elderly patients with chronic kidney disease (CKD),and to explore the relationship between inflammatory molecules in venous blood and atherosclerosis.Methods Totally 87 elderly patients and 64 middleaged patients with CKD were selected.The vein fasting blood samples were taken in the morning.Serum levels of interleukin (IL)-18,IL-6,tumor necrosis factor (TNF-α),high-sensitivity C-reactive protein (hs-CRP) were measured by enzyme-linked immunosorbent assay (ELISA) and ankle-brachial pulse wave conduction velocity (baPWV) was detected.Results Inflammatory molecules such as IL-18,IL-6,TNF-α and hs-CRP levels in venous blood were increased with the severity of CKD in both two groups,and the levels of inflammatory molecules were higher in elderly group than in middle-aged group.There was a signifiant difference in the detection rate of patients with baPWV＞1400 cm/s between elderly group and middle-aged group [30 cases (34.5％) vs.11 cases (17.2％),x2 =5.58,P＜0.05].The prevalence of PWV＞1400 cm/s was higher in patients with hyperlipidemia and hypertension than in patients with diabetes or heart disease (elderly group:100％,100％ vs.45.5％,40％; middle-aged group:80％,100％ vs.28.6％,33.3％,respectively; P＜0.05).The inflammatory protein (IL-18,IL-6,TNF-α and hs-CRP) levels were significantly higher in patients with baPWV＞ 1400 cm/s than those with baPWV ＜ 1400 cm/s (P＜0.05).Conclusions The degree of atherosclerosis is more severe in elderly CKD patients than in middle-aged CKD patients,which needs to be taken seriously enough.

Statistical analysis of TCM syndrome differentiation and clinical symptoms were made in 163 cases of diseases of digestive tract. It was found that the patients of abnormal defection or tendecy of abnormal defecation with the hyperactive liver - Qi attacking the spleen, stagnation of liver-Qi due to hypofunction of the spleen, loose stool due to deficiency of the spleen, constipation due to Qi-deficiency, constipation due to Qi - staganation syndromes accounted for 60%- 100%. Elecrtic examination of colon on the body surface and analysis of frequancy spectrum found that hyperelectroactivity of low - frequency and high - frequency segment of colon and contractive complex myoelectric hyperactivity in the patients of the hyperactive liver - Qi attacking the spleen; hyperelectroactivity of high - frequency segment of the ascending and descending colon and contractive complex myoelectric hyperactivity and decrease of electric activity of high - frequency segment of the sigmoid colon in the patients of loose stool due to hypofunction of the spleen: obvious decrease of electric activiy of low - frequency and high-frequency of the colon and contractive complex myoelectric hyperactivity in the patients of constipation due to deficiency of Qi or Qi - stagnation, but electric activity of the high -frequency segment of the colon and contractive complex myoelectric activity after meal in the patients of constipation due to Qi -stagnation was stronger than that in the patients of constipation due to Qi - deficiency. Electric frequency spectrum of colon can indirectly reflect changes of colon dynamics of different syndromes, and it can partially expain the changes of stool and the mechanism of relative symptoms.

Objective To evaluate the diagnostic value of the combination of serum DKK1 (Dickkopf-1 )and P53 autoantibodies in patients with esophageal squamous cell carcinoma (ESCC).Methods Serum levels of DKK1 and P53 autoantibodies were measured by enzyme-linked immunosorbent assay (ELISA) for the 1 26 patients with ESCC and 60 normal controls.Receiver operating characteristics (ROC)was used to calculate the diagnostic efficiency.Results The serum levels of DKK1 and P53 autoantibodies were signifi-cantly higher in ESCC than those in normal controls [(673.09 ±343.82)pg/ml vs (362.05 ±1 48.07)pg/ml, Z =6.1 58,P <0.000 1 ;(0.398 ±0.546)vs (0.069 ±0.050),Z =3.832,P <0.000 1 ].ROC curves showed the optimum diagnostic cutoff for serum DKK1 was 588.77 pg/ml,with an area under curve (AUC)of 0.780 (95%CI:0.71 5 ~0.844,61 .9% sensitivity,95.0% specificity).Measurement of P53 autoantibodies demonstrated an AUC of 0.674 (95%CI:0.598 ~0.750,45.3% sensitivity,95.0% specificity).The com-bination of DKK1 and P53 autoantibodies yielded an AUC of 0.843 (95%CI:0.788 ~0.897,73.8% sensitiv-ity,95.0% specificity).In early-stage ESCC,combined detection of DKK1 and P53 autoantibodies improved the diagnostic power,with an AUC of 0.903 (95%CI:0.845 ~0.961 ,81 .0% sensitivity,95.0% specifici-ty).Conclusion Serum DKK1 and P53 autoantibodies can be used as potential diagnostic biomarkers for the ESCC.Combined detection of them might aid the early diagnosis of ESCC.

Objective To reduce infection risk in hemodialysis patients through analyzing the causes of over stand-ard colony forming unit(CFU)and conducting bacteriological detection of hemodialysis concentrated B solution. Methods According to microbial monitoring results of hemodialysis concentrate B solution in a hospital between November 2011 and May 2012,disinfection frequency of B solution was changed and dispensing container was covered during the process of using,four groups were divided according to different measures (group A disinfected twice a week,covered dur-ing the process of using;group B twice a week;group C once a week;group D once every two weeks),monthly bacte-riological detection of B solution was conducted,condition before and after disinfection of four groups were com-pared.Results Bacterial count in group A,B ,C and D was(25.41 ±15.08),(28.24±28.04),(68.58 ±22.58), and (75.25±26.63)CFU/mL,respectively (F =79.00,P <0.01 );bacterial count of group A,B,and C after in-tervention were all lower than group D before intervention (all P <0.01),bacterial count of group A and B was the lowest.The qualified rate of group A was 100.00%,the unqualified rate of group B,C,and D was 13.95%, 24.24%,and 35.94% respectively(χ2 =28.70,P <0.01 ),the unqualified rates of group A,B,and C after inter-vention were all lower than group D.Conclusion Hemodialysis concentrated B solution should be used within 24 hours after preparing,disinfected twice a week,and covered during the process of using ,so as to control B solution colony number within the standard level.

In 51 patients with gastrointestinal diseases,diseases,abdondnal X-lay Photos at lying POSition weretaken 6.5 hours after barium ined and 12 healthy volunteers served as coneal. The longitudinal axis,the transverse diameter,the number and the height of colonic bags in the colonic X-ray photes at fillingand evacuating Phases were counted.Chronic colitis was mainly manifested as loose stool, alternation ofconstipation and diarrhea,dyschesia or abdominal pain whenever desire to defecate. The colonic X-rayphotos showed that the diameter and the number of colonic bag in chronic colitis were reduced and the evacuation of barium became accelerated.These colonic X-ray images can explain the pathophysiologicmechasm of the above manifestations and may serve as a kinetic index providing evidence for the clinicaldiagnosis and treatment of the disease.
