The efficiency of conservative treatment for cervical radiculopathy was retrospectively reviewed. Eighty-one patients were included; 40 patients presented with C7, 37 with C6, 2 with C5, and 2 with C8 radiculopathy. Seventy-eight patients underwent MRI examination prior to treatment, showing intervertebral disc protrusion in 71 cases, and spinal stenosis in 7. Eighty-one patients underwent a treatment wearing a cervical collar and home-based halter cervical traction: 5-6 kg for 20 minutes, once a day for 3 to 6 weeks. The mean duration of symptoms prior to neurosurgical evaluation was (43.0?8.3) days. Sixty-three (78%) of 81 patients responded to therapeutic traction, experiencing significant or total pain relief, three could not tolerate the traction, and traction failed in 15 patients. Three (1.89%) of the 63 patients undergoing traction treatment suffered recurrence of symptoms and required surgery.

Objective To explore the role of hemoglobin (Hb) level in mortality and morbidity of chronic kidney disease (CKD)patients,aiming to give some evidence for therapy of anemia.Methods Randomized,clinical trials (RCTs) were identified by searching Medline,Embase and the Cochrane library.All the analyses were performed using the Revman software available free from the Cochrane collaboration.Results Twenty-three trials involving 10 204 patients were identified.Overall,the high Hb target was associated with increased risk of all-cause mortality (RR=1.10,95％ CI 1.00 to 1.21),hypertension (RR=1.40,95％ CI 1.12 to 1.75),stroke and hospitalization (RR=1.07,95％ CI 1.00 to 1.14) compared with low Hb target (P＜0.05).No significant difference was found in the risks of non-fatal mycardial infarction (RR=1.13,95％ CI 0.79 to 1.62) and renal replacement therapy (RR =1.00,95％ CI 0.85 to 1.18).Conclusions Targeting low Hb target is beneficial to CKD patients based on reduced risk of hypertension,hospitalization,stroke and all-cause mortality.However,no significant difference is found in non-fatal mycardial infarction and renal replacement therapy.

OBJECTIVE To analyze the risk factors of the Catheter-Related Blood Stream Infection(CRBSI) in the intensive care unit(ICU),and to approach effective methods for preventing the CRBSI in ICU.METHODS With the method of objective investigation,all patients in ICU from Jan,2008 to Dec,2008 were studied.The risk factors of CRBSI were investigated.RESULTS 257 patients entered the study.A total of 147 cases suffered from the nosocomial infection(NI).The incidence rate of the NI was 57.2%.Among these,36 cases were dignosised of the CRBSI,and the case-infection rate was 14.07%.The number of CRBSI account for 24.49% of the patients who suffered from the NI.The nosocomial infection rate perday the CRBSI was 16.57‰.It was significantly higher than that of the general wards′.The pathogen detection showed the main pathogen was the G+ bacteria,accounting for 54.04%.Then was the G-bacteria,accounting for 37.84%.The fungus accounted for 8.11%.11 unusual drug resistance bacteria were found(6 ESBLs positive bacteria and 5 MRS bacteria).CONCLUSIONS The incidence of the CRBSI is related to the following reasons: days and the sites of the catheter being placed,the procedure the medical personnel done,the immune function of the patients,and the utilization or unutilization of the high-nutrition drugs through the vein.According to these reasons,strict aseptic technique,reasonable choice of the catheter site,shortening the duration the catheter insertion,and maintaining catheter unobstructed are the keys to prevent the incidence of the CRBSI.

Objective To explore the drainage effect of drainage tube with different materials on the basis of a constant nega tive pressure drainage,and its impact on flap survival.Methods The most common clinical used Polyvinyl chloride resin (PVC)pipe,latex tubes,silicone tube drainage tubes,and flaps were compared at different phases of the drainage,to determine the best clinical flap with drainage material.After three groups of flaps were designed,including a constant negative pressure drainage device,without a constant negative pressure drainage system,and drainage alone (no negative pressure) drainage flap,the flap survival was observed at different phase space.Three different drainage drainage ways of the flap and the flap survival area of effect were statistically analyzed.Results The silicone tube drainage was more fully and effectively.Constant negative pressure drainage volume of liquid was up to the flap with drainage to the fullest,the highest rate of skin flap healing,and better healing.Conclusions The constant negative pressure in the drainage of the flap makes drainage more fully,and promotes rapid healing of wounds,while the silicone tube is suitable for flap drainage.
