ObjectiveTo analyze the characteristics of severe trauma patients with acute kidney injury (AKI) receiving renal replacement therapy (RRT), in order to look for the risk factors of AKI and the opportune time for the initiation of RRT on prognosis.Methods A retrospective cohort study involving consecutive patients with severe trauma in emergency intensive care unit (ICU) in the Second Affiliated Hospital of Zhejiang University School of Medicine, from August 2011 to December 2014, was conducted. Inclusion criteria included age≥18 years, injury severity score (ISS)> 16, AKI receiving RRT, and the duration of hospital stay> 24 hours. The general data, the risk factors of AKI, the prognostic indicators, and the information of RRT were recorded. All patients were divided into two groups according to the prognosis, the time of onset of AKI and the initiation time of RRT. The independent risk factors for prognosis were screened by binary logistic regression analysis.Results Seventy-three patients were eligible for enrollment, including 48 deaths (65.8%); 49 patients suffered from AKI≤48 hours after trauma (early stage group), and in 24 patients it was longer than 48 hours (late stage group). In 55 patients RRT was routinely started (routine RRT group), 18 patients underwent RRT ahead of routine criteria decided by the judgment of the attending doctor (earlier RRT group). The main risk factors of RRT in traumatic patients with AKI were shock and sepsis, each accounted for 90.4% and 53.4%. Compared with survival group, in death group, the proportion of male patients was lower (70.8% vs. 100.0%,χ2 = 7.238,P = 0.007), acute physiology and chronic health evaluationⅡ (APACHEⅡ) scores were higher (23.7±5.1 vs. 14.4±3.7,t = 8.031,P< 0.001), Glasgow coma score (GCS) was lower [5.0 (3.0, 15.0) vs. 15.0 (8.0, 15.0),U = 320.000,P = 0.001], incidence of shock and sepsis was higher (97.9% vs. 76.0%,χ2 =6.755,P = 0.009; 64.6% vs. 32.0%,χ2 = 7.014,P = 0.008), the rate of use of contrast medium was lower (27.1% vs. 56.0%,χ2 = 5.898,P = 0.015), the time for the diagnosis of AKI post trauma was delayed [days: 2 (1, 5) vs. 2 (1, 2), U = 762.000,P = 0.049], the time for the initiation of RRT post trauma was later [days: 6.0 (3.0, 12.0) vs. 3.0 (2.0, 4.5), U = 868.500,P = 0.002], the recovery rate of renal function at discharge was lower (10.4% vs. 100.0%,χ2 = 54.497, P< 0.001). Compared with late stage group, in early stage group, the mortality was lower (55.1% vs. 87.5%,χ2 =7.509,P = 0.006), and the incidence of sepsis before AKI was also lower (38.8% vs. 83.3%,χ2 = 12.854,P< 0.001). Compared with routine RRT group, the recovery of renal function at discharge was better with a lower mortality rate in the earlier RRT group, but the difference was considered to be insignificant (55.6% vs. 36.4%,χ2 = 2.064,P = 0.151;50.0% vs. 70.9%,χ2 = 2.633,P = 0.105). Logistic regression analysis showed GCS [odds ratio (OR) = 0.852, 95%confidence interval (95%CI) = 0.747-0.972,P = 0.017], shock before AKI (OR = 85.350, 95%CI = 5.682-1 282.073, P = 0.001), and sepsis before AKI (OR = 11.499, 95%CI = 2.127 - 62.161,P = 0.005) were independent risk factors for the judgment of prognosis.Conclusions Shock and sepsis are the major risk factors of RRT in trauma patients with AKI. Shock, sepsis and traumatic brain injury are the independent risk factors of death. Perhaps early initiation of routine RRT cannot improve the outcome of the patients with posttraumatic renal insuficiency.

Objective:To study intervenient action of Qixue Bingzhi Prescription on the patient of cervical atherosclerosis(AS). Methods:63 cases of cervical AS were randomly divided into a treatment group(n=33) and a control group(n=30), with 25 cases of same age ranges used as healthy group. The control group was treated with basic treatment of western medicine and the treatment group with the basic treatment plus Qixue Bingzhi Prescription for one month. Changes of blood lipid metabolism, interleukin levels, supersensitive C-reactive protein(Hs-CRP) content and the leukocyte adherence expression rate were observed. Results: The total cholesterol (TC), triglyceride(TG), AS index (TC/HDL-C), interleukin-6 (IL-6), interleukin-8 (IL-8) and Hs-CRP levels and lymphocytes and the neutrophilic granulocyte adhesion molecule expression rate (ICD11b and zCD11b) decreased significantly(P 0. 05), Conclusion: Qixue Bingzhi Prescription can effectively and safely intervene in blood lipid metabolism and inflammatory reaction in the patient of cervical AS, and it has prospect of development in preventing formation of AS and stabilizing plaque.

Objective To explore the effect of fuzhengyangyingtang (FZYYT) on bone marrow proliferation in aplastic anemia (AA) mice. Methods AA mice models were set up according to Yaojun descriptive method, and then were randomly divided into FZYYT group, CsA group, FZYYT+CsA group, and AA group, each group containing 10 animals. 10 healthy mice served as control. The former three groups were fed with FZYYT, CsA and FZYYT+CsA, respectively, and the last two groups were fed with normal saline. After fed 10 days the changes in hemoglobin(Hb), platelet, BMNC and bone marrow hematopoiesis tissue volume were determined. Resutls Hb, platelet, BMNC and bone marrow hematopoiesis tissue volume obviously increased in groups FZYYT and CsA compared with AA group, and were the highest in group FZYYT+CsA. Conclusion The results indicated that FZYYT was effective in the treatment of AA.

Objective To develop a gas chromatographic (GC)method for simultaneously determination of benzyl alcohol,2-phenoxyethanol,methyl-p-hydroxy benzoate (PHBA-Me?雪,ethyl-p-hydroxybenzoate(PHBA-Et?雪,isooropyl-p-hydroxybenzoate(PHBA-iPr?雪,propyl-p-hydroxybenzoate (PHBA-Pr),isobuty-p-hydroxy benzoate(PHBA-iBu)and butyl-p-hydroxy benzoate(PHBA-Bu)in cosmetics. Methods The 8 kinds of preservatives could be separated completely using the packed column and their peaks were not interfered by the other components in cosmetics. Results The detection limits of were 0.27,0.38,0.78,0.83,0.95,1.40,1.50 and 2.1ng respectively. The linear ranges of benzyl alcohol,2-phenoxyethanol and PHBA-iPr were 25-1 000 mg/L and the linear ranges of PHBA-Me?PHBA-Et?PHBA-Pr?PHBA-iBu and PHBA-Bu were 25-500 mg/L. The recoveries were between 92.6%-101.3% and the relative standard deviations(RSD)were between 2.31%-6.44%(n=6?雪. Conclusion The method was simple,rapid,sensitive and accurate.

Extraction of teeth is the most basic and widely used operation of oral and maxillofacial surgery. According to characteristics of extraction of teeth, the author views medical ethics principles which in the diagnoses and treatments process from the aspect of medical ethics, they are,①Doctors must intensify their own quality and self - cultivations and establish the idea of " People First ". ②Doctors must carry on the overall and systematic inspection, make the plan of diagnoses and treatments synthetically toimplement the idea of " People First ". ③Doctors should pay attention to interact with patient, meet different patients' demands and create the harmonious medical environment.

This paper reports the diagnosis and treatment of 2 cases of acute schistosomiasis with ectopic lesion in the lung. It suggests that in schistosomiasis endemic areas,if the patients with the contact history of infested water have the symptom of fe-ver,while the effects of anti-infection and the corresponding treatments are not good,the clinician should consider acute schisto-somiasis.

Objective To explore the probable mechanism of tinnitus and the accompanied symptoms us-ing RS-FMRI. Methods We recruited 10 adults with chronic tinnitus and 10 health adults for fMRI in the resting state. Then we compared the differences of regional homogeneity(REHO)maps and functional connectivity to the whole-brain maps with the auditory cortex as a region of interest between the two groups. Results The REHO maps of tinnitus group showed significant differences in the automated anatomical labeling brain map including the middle frontal_gyrus (right),superior frontal_gyrus (left),entorhinal cortex_(right),middle occipital_gyrus (right),middle occipital gyrus(bilateral),lingual gyrus(left)and cuneate lobe(left). The functional connectivity maps of tinnitus group showed significant differences in lingal_gyrus(left)of AAL brain regions. The p threshold value was<0.001 in all results. Conclusion Tinnitus may cause abnormal neural activity in several non-auditory brain regions,which may be the neurophysiological mechanism of tinnitus accompanied symptoms.
