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.

Plasma cell mastitis,also known as periductal mastitis or mammary duct ectasia,always occurs in young women.Because of It's Complicated and varied clinical manifestations,it is easily misdiagnosed as breast cancer.Early diagnosis and staging helps to avoid unnecessary surgery.At present,There is no unified understanding to this kind of disease.Modern medicine mainly treated it by surgery while Traditional Chinese medicine believes it shoull be treated internally and externally.Complete resection of the lesion and the cosmetic effect is the focus of current research.This article reviews the progress of research in plasma cell mastitis etiology,pathology,diagnosis and treatment.

Objective] To observe the clinical effects of Tianwang Buxin decoction in the treatment of heart Yin deficiency type of Generalized Anxiety Disorder. [Methods] 63 patients with Generalized Anxiety Disorder(heart Yin deficiency type) were randomly divided into three groups: Tianwang Buxin decoction group, paroxetine group, Tianwang Buxin decoction combined paroxetine group, course of treatment for 8weeks.Contrast the scores of three groups by HAMA before and after treatment. [Results] The clinical efficacy was almost the same among the three groups without significant difference, but the decrease of HAMA scores of Tianwang Buxin decoction combined paroxetine group was obviously lower than Tianwang Buxin decoction group and paroxetine group(P<0.05), among which, TCM group and combination group of TCM and WM had less side effect than WM group. [Conclusion]The clinical efficacy of Tianwang Buxin decoction group is almost the same with the paroxetine group without significant difference. The clinical efficacy of Tianwang Buxin decoction combined paroxetine group is more significant.

Objective To study the clinic effect and safety of inhaled nitric oxide for the neonates with hypoxic respiratory failure. Methods A total of 21 neonates with hypoxic respiratory failure were trea-ted with nitric oxide inhalation after ineffective treatment of conventional mechanical ventilation. The values of mean airway pressure( MAP) ,oxygenation index( OI) ,mean blood pressure and saturation of blood oxy-gen percutem( TcSaO2 ) were detected before and after nitric oxide inhalation. Meanwhile,the values of coag-ulation function,nitrogen dioxide concentration and methaemoglobin were monitored. Results The lung oxy-genation of 21 cases were significantly improved in 48 hours after nitric oxide inhalation,OI declined from 26. 600 ±4. 169 to 7. 500 ±1. 716,MAP decreased from(15. 100 ±2. 132)cmH2O(1 cmH2O=0. 098 kPa) to (8. 000 ± 0. 816) cmH2O,which all had statistical differences(P <0. 01). The monitoring of coagulation function was in the normal range. The levels of methaemoglobin were less than 3% and nitrogen dioxide less than 1 × 10 -6 . In this study,18 neonates survived,2 neonates died and 1 neonate gave up treatment. Conclu-sion Inhaled nitric oxide early can improve oxygenation effectively for neonates with hypoxic respiratory failure without obvious side-effect. However,it is not yet clear for its long-term prognosis and whether there is influence development of the nervous system.

Objective To investigate the imaging features in neonates with hypoglycemic brain injury by early and serial MRI.Methods Neonates who were admitted to neonatal department from May 2005 to Jul 2013 received MRI and diffusion-weighted imaging(DWI) scan within 7 days after hypoglycemia.Fortynine neonates were diagnosed with hypoglycemic brain injury.Thirty-four neonates received second MRI scan between 2 ～3 weeks after hypoglycemia.Seven neonates received third MRI scan.Results All the 49 neonates showed hyperintensity on DWI in the regions of occipital and parietal lobe for the first MRI scan(mainly involved 33 cases).Six cases combined frontal lobe and temporal lobe.Ten cases presented widespread cortex and white matter involvement.All the cases presented hypointensity on DWI for the affected area,T1 and T2 weighted image signal changes were not obvious.Some cases presented deep white matter and gray matter injury.Thirty-four cases received second MRI scan between 2 ～3 weeks after hypoglycemia,20 presented hypointensity on DWI,hypointensity on T1 weighted image and hyperintensity on T2 weighted image.Eleven cases with normal signals,and the other 3 were absorbing.Seven cases received third MRI scan,appeared encephalomalacia,myelin retardation,white matter volume decreased,hypoplasia of corpus callosum.The more severe the clinical symptoms was,the more severe the degree of brain injury showed.Conclusion Cerebral occipital and parietal regions are the most vulnerable in neonatal hypoglycemic brain injury.Early DWI for the imaging diagnosis of hypoglycemic brain injury should be taken within one week after hypoglycemia.Mild injury is recoverable,but severe would chang into necrosis and encephalomalacia.Some combined deep white and gray matter injury might related to hypoxia and ischemia.

OBJECTIVE： To investigate the possible role of the alteration of mitochondrial transmembrane potentials(Δ Ψ m) in arsenic trioxide(As2O3)-induced apoptosis of human gastric adenocarcinoma cells(SGC7901).METHODS： Cell apoptosis was assessed through morphology， cell viability， the percentage of sub-G1 cells and phosphatidylserine(PS) externalization.the Δ Ψ m was detected on flow cytometry through double staining of Rhodamine 123 (Rh123) and propidium iodide(PI).RESULTS： The As2O3-induced apoptosis was associated closely with the disruption of the Δ Ψ m.CONCLUSION： The disruption of the Δ Ψ m is one of the mechanisms of As2O3-induced apoptosis.

Objective: To investigate the effect of growth hormone(GH) and hypo calorie enteral nutrition(EN) on protein metabolism in patients after cardiac operations. Methods: 36 patients after cardiac operations were randomly divided into two groups. The test group received GH and EN, and the control group received EN only. The treatment was maintained 7 days postoperatively. Plasma albumin(A)?transferrin(TF)?prealbumin (PA)?retinol binding protein(RBP) on the preoperative day and day 1,4,8 postoperatively and nitrogen balance(NB) on the day 1,2,3,5,7 postoperatively were detected. Results: There was no significant difference of all plasma protein levels between two groups before operation and all decreased on the 1st postoperative day, but only RBP higher in the test group than that in the control. There was significant difference in TF,PA,RBP levels on the 4th and 8th postoperative day, the plasma A level on the 8th postoperative day, and NB on the 1st to 7th postoperative day between the two groups. Conclusion: Combined use of GH and EN can elevate plasma A,TF,PA,RBP levels and improve negative NB.
