The optimal intensity of continuous renal-replacement therapy in severe acute kidney injury is uncertain,but the establishment of optimal dose of CRRT is the key to successful treatment.In this paper,the basis for setting dose of CRRT starts analysis of the current CRRT dose and the efficacy of the evidence in evidence-based medicine and problems and presents the need of severe acute renal injury for greater CRRT dose.The purpose is to guide clinicians to set an optimal CRRT dose and improve the prognosis of severe acute renal injury.

The paper reviews the causes of the anemia in patients with chronic kidney disease(CKD)and focuses on the diagnosis.Meanwhile,we also systematically introduce the treatment strategies for patients with anemia and CKD,especially for the reasonable clinical application of erythropoiesis-stimulating agents(ESAs)and iron.The problems in diagnosis and treatment of anemia in CKD patients are also proposed.The objective of this paper is to standardize the clinical diagnosis and treatment of anemia in CKD patients,so as to promote the treatment of CKD in grassroot hospitals.

Objective:To find out heatshock protein HSP27 interactingproteins in the hepatocellularcarcinoma(HCC).Methods:HSP27 interacting proteins in the human HCC HepG2.2215 cells were seperated and identified.HSP27 binding proteins were recovered by antiHSP27 antibody immunoprecipitation with the total proteins from HCC HepG2.2215 cells.After in-solution digested and analyzed by LC-ESI-ITMS/MS,the recovered protein complexes were identified by peptide sequence tags(PST)and database searching,and were confimed by immunoprecipitation and Western blot analysis.Results:Seven HSP27 binding proteins were firstly identified by database searching,which were HSP90,GRP-78 and HSP70 of HSP70 family members,lysyl hydroxylase,Keratin 9,Keratin 10,Keratin 1.The identified seven HSP27-interacting proteins by IP coupled with MS could be classified into three functional categories based on their functions:chaperones,cytoskeleton organization,metabolic enzymes.Conclusion:HSP27 in HCC is a related proteins involved in the regulation,by interacting with some peptides,or small molecule protein to control the tumor development.

Patients with systemic lupus erythematosus,especially lupus nephritis,are often accompanied by arterial and venous thrombus at various sites.Thrombosis is associated with the extrinsic and intrinsic coagulation pathway activated by inflammation and endothelium injury.Anticoagulant therapy can interrupt the cycle between inflammation and thrombus,which not only prevents and treats the thrombotic disease but also lessens the inflammatory reaction in kidney and attenuates the renal injury.

The development of Continuous renal replacement therapies(CRRT) in saving the critically ill patients is rapidly because of its removing the toxins and inflammatory mediators,maintaining the balance of the internal enviroment and preventing the endothelial cell function.The aim of the present paper is to guide and standardize the clinical usage of CRRT in the primary hospitals,through clarifying some problems of CRRT in clinical practice,such as the selection of CRRT pattern,setting the blood flow rate and the prescription and dosage of replacement fluid in CRRT,the selection of anticoagulant and the anticoagulation strategy and the announcements in CRRT.

Objective Pulmonary sequestration (PS) is a rare disease,and its clinical symptoms are usually related to subsequent pulmonary infections.We analyzed the clinical characteristics of PS complicated by aspergillosis,and reviewed related literature,so as to disclose the association between these two diseases.Methods Sixty-nine patients with surgery-confirmed PS in Peking Union Medical College Hospital between January 1990 and December 2013 were retrospectively analyzed,including seven cases complicated by aspergillosis.Clinical manifestation,imaging and surgery of these patients were analyzed.Literature focusing on PS complicated by aspergillosis in pubmed data base was reviewed.Results In these seven patients,four cases were male,and three cases were female.Age at diagnosis ranged from 29 to 58 years old.The interval from onset to definite diagnosis ranged from two weeks to 20 years.Clinical symptoms included productive cough in seven cases,hemoptysis in three cases,chest pain in two cases,and fever in one case.All cases were intralobar PS with four in the left lower lobe and three in the right lower lobe.Consolidation in chest CT was noted in six cases.Cavitation was positive in three cases.Surgery of lung lobe resection was performed in all patients.Aberrant arteries were found during operation with the origin from aortic artery in four cases,phrenic artery in two cases,and intercostal artery in one case.Aspergillosis was diagnosed by pathology in six cases and by lung tissue culture in one case.Conclusions PS complicated by aspergillosis is extremely rare,but the trend of an increase in recent years has been noted.Strict and cautious examinations for microorganisms and pathology will help find relatively insidious aspergillosis.

Objective To evaluate the effect of preoperative intramuscular injection of of dextromethorphan in three dosages on fentanyl consumption in postoperative PCA in order to optimize its pre-emptive analgesia dose. Methods 80 ASA Ⅰ-Ⅱ patients underwent spine operations under general anesthesia were randomly divided into four groups, who respectively received intramuscular dextromethorphan 10mg (DM10 group), 20mg (DM20 group), 40mg (DM40 group), or normal saline (CON group) respectively. The PCA fentanyl consumption as well as VAS pain scores were observed 4h, 24h, and 48h after the operation. Results Although there was no significant differences in pain VAS score between the four groups, the fentanyl consumption was significantly lower in groups DM20 and DM40 compared with group CON and DM10. However, there was no significant difference between group DM20 and group DM40. Conclusion Preoperative IM dextromethorphan shows a dose-dependant fentanyl spare effect on postoperative PCA, and a dose of 20mg seems to be optimal for preoperative use.

Objective To study the effect of recombinant human erythropoietin (rHuEPO) on in aged patients undergoing maintenance hemodialysis. Methods Blood pressure and its mechanism 52 elderly patients undergoing maintenance hemodialysis divided into two groups, HBP group (23 cases with hypertension) and NBP group(29 cases without hypertension). The plasma vasoactive substances were measured by radioimmunological methods. Fifteen cases in NBP group as EPO group were given a bolus of venous injection of rHuEPO (3 000 IU), others in NBP group (14 cases) were injected 0.9% saline as control group. The plasma vasoactive substances were assayed before and 1, 3, 6, 9, 12, 18, 24, 30, 44 hours after therapy with or without rHuEPO. Results (1) The plasma dopamine (DA) in HBP group were significantly higher than that of NBP group. (2) Endothelin levels increased transiently but DA levels increased steadily in EPO group. Conclusions The study suggests that the effect of rHuEPO induced on hypertension in the elderly patients undergoing maintenance hemodialysis is associated with the increasing plasma DA.

Objective To prepare mouse polyclonal antibody against human Nanog by genetic immunization and to identify this antibody by Western blot and immunofluorescence. Method The antigenicity fragment (A16-V101) of human Nanog (hNanog) was chosen by analysis of Accelrys software, and its cDNA (258bp) was amplified from plasmid containing full-length cDNA of hNanog, then it was cloned into pBQAP-TT to construct recombinant plasmid pBQAP-TT-hNanog for genetic immunization. Mice were immunized with this recombinant plasmid and two other adjuvant plasmids-pCMVi-GMCSF and pCMVi-FIT3L, which help to enhance the antibody's generation. After 12 weeks, we obtained mouse anti-hNanog antibody from mice blood serum. The antibody titer was determined by enzyme-linked immunoadsordent assay (ELISA), and its specificity was identified by Western blot in human renal protein. Using this antibody, we detected hNanog expression in HKC cells of hNanog-AAV2 transfection. Results Recombinant plasmid pBQAP-TT-hNanog for genetic immunization was confirmed to be correct by restriction digestion and sequencing. The result of ELISA showed that the antibody titer was 1∶3 200. This antibody recognized a band of 34kD hNanog protein in human renal protein by Western blot. Immunofluorescence showed that Nanog protein was mainly located in the nuclei in hNanog transgene HKC cells. Conclusion Genetic immunization can offer mouse anti-hNanog polyclonal antibody of high titer and high specificity.
