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.

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 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.

Cultured porcine endothelial cells (EC) produce and secrete plasminogen activators (PA). If the serum free medium conditioned by vascular smooth muscle cells (SMC-CM) mixed with the medium conditioned by endothelial cells (EC-CM), the PA activities of the latter decreased significantly. Coeultivation of EC with SMC inhibited 70.7% PA activity of EC. Gel eletrophoretic analysis (SDS-PAGE) of SMC-CM followed by reverse fibrin autography demonstrated PA inhibitory activity in the molecular weight range of 49, 000-52, 000 similar to those identified by Laug (1985).In this study it was also investigated the effect of a Chinese herbal medicine-Radix Salviae Miltiorrhizae (RSM) on the inhibitory activity. SMC were incubated with RSM (0.1% in M-199, the final concentration was 1.5mg/ml) for 24hr. The SMC-CM collected before and after RSM treatment were mixed with EC-CM and urokinase respectively. The results show that the residual PA activities in EC-CM or urokinase samples mixed with SMC-CM treated with RSM were significantly higher than that mixed with SMC-CM without treatment with RSM. SMC-CM neutralized the PA activities in EC-CM or urokinase samples in a concentration dependent manner (P
