Objective To expolre the clinical characteristic of hospital acquired acute renal failure(HA-ARF).Methods To retrospectively analyse the clinical datas of 103 patients who were suffered from acute renal failure in the duration of hospital stay within 5 years,which was compared with the homeochronous community-acquired acute renal failure(CA-ARF).Results In the 103 cases of HA-ARF,the incidence rate was 32.04% in the major age range from 60 to 74 years old,infection was the most important factor(33.01%),then other factors were cardial and cerebrovascular diseases(17.48%),acute hypovolemia(14.56%) and operation(9.71%);The complicating other organ nonfunction(34.95%),and the mortality rate was 39.80%,all the factors in HA-ARF were higher than that in CA-ARF.Conclusion The main factors of origin in HA-ARF are infection,cardial and cerebrovascular disease,acute hypovolemia and operation.The mortality rate of this disease is higher.Etilogical treatment promptly and dialysis regimen are the main means to rescue these patients.

OBJECTIVE To investigate the knowledge of Helicobacter pylori infection among outpatients,analyzing the data and providing useful information and measures for H.pylori infected and uninfected patients. METHODS Questionnaires about the knowledge of H.pylori were operated on 286 patients randomly selected from patients taking gastrointestinal endoscopy in October,2005. RESULTS Among 286 patients investigated,177 cases(61.9%) took the examination for diagnosis,while 157 cases(54.9%) had upper abdominal symptom more than 12 months.There were 60% patients investigated who knew only 2 items from total(7 items) about H.pylori in the questionnaires,while 46.7% patients wanted to obtain the knowledge of the disease and instructions on health care from medical professionals.In addition,it showed that there was no close relation between education level and knowledge of the disease. CONCLUSIONS Investigating the knowledge of special disease,which mastered by the patients,will help to identify patients blind to the disease they have,and patients who are in need of health-care instructions.

Objective To study the setting up a model of orthotopic liver transplantation (OLT) in pigs. Methods In pigs, OLT were performed based on the porcine anatomical and physiological features, and the extracorporeal veno venous bypass was established during the anhepatice stage. Results Fourteen pigs(87.5%) of 16 OLT survived after the operation, and the haemodynamics?serum biochemical parameters and core temperature were maintained in the normal value during OLT. Conclusions Extracorporeal venovenous bypass and perfect surgical techniques based on the anatomical and physiological features are the key to successful OLT in pigs.

OBJECTIVE:To investigate the effects of 3 types of antihypertensive drugs on cognitive function in elderly hyper-tensive patients after acetabular surgery. METHODS:Ninety hypertensive patients receiving antihypertensive drugs for a long term (not changed antihypertensive drugs within 2 weeks before surgery)undergoing selective acetabular surgery were included sequen-tially and divided into angiotensin receptor blocker(ARB)group,angiotensin converting enzyme inhibitor(ACEI)group and cal-cium channel blocker(CCB)group according to the types of antihypertensive drugs,with 30 cases in each group. All patients re-ceived acetabular surgery under epidural anesthesia. The cognitive function of patients was evaluated by using MMSE 1 d before sur-gery(T0),1 d after surgery(T2)and 3 d after surgery(T3). The concentration of S100β protein serum was determined 1d before surgery (T0),immediately after surgery (T1) and 1 d after surgery (T2). RESULTS:Compared with T0,MMSE score of ARB group at T2,those of ACEI group and CCB group at T2 and T3 were decreased significantly,with statistical significance(P<0.05). Compared with ARB group,MMSE score of ACEI group and CCB group at T2,T3 were decreased significantly,with statistical sig-nificance(P<0.05). Compared with ACEI group,MMSE score of CCB group at T2,T3 were decreased significantly,with statisti-cal significance(P<0.05). Compared with T0,the concentration of S100β protein in serum 3 groups were increased significantly, with statistical significance (P<0.05). Compared with ARB group,the concentration of S100β protein serum in ACEI group and CCB group were increased significantly,with statistical significance(P<0.05). Compared with ACEI group,the concentration of S100β protein serum in CCB group at T1,T2 were increased significantly,with statistical significance(P<0.05). The incidence of cognitive dysfunction was in ascending order of ARB group (30%)

Purpose To study the expression of Ech1 in hepatocarcinoma and its clinical significance, and to explore the relationship between subcellular location of Ech1 and malignant biologic behaviour of hepatocarcinoma. Methods Immunohistochemical analysis was used to detect Ech1 expression in the 20 cases of normal liver tissue and the 30 cases of hepatocarcinoma. Subcellular location of Ech1 in Hca-F and FEch1-down cell was observed with subcellular protein extraction. Results The expression of Ech1 in primary hepa-tocarcinoma was increased compared to that of normal liver tissues ( P<0. 05 ) , while there was no significant difference between the expression of Ech1 with the age, AFP, and with or without liver cirrhosis or hepatitis virus in hepatocarcinoma (P>0. 05). Ech1 was found expressed almost at the same location although the expression level one is normal and the other is downregulation. Ech1 expres-sion was found in cytosol, membrane fraction, and its expression was higher in cytosol than other fractions both in Hca-F cell and Ech1 downregulated Hca-F cell. Conclusions The expression of Ech1 in primary hepatocarcinoma was increased, which may indicate that Ech1 is a critical factor in the development of primary hepatocarcinoma, but the subcellular location of Ech1 has not much contribution to that.

OBJECTIVETo maked a Nrf2 down-regulated cell line by over-expressing Keap1 in H460 cells to study the role of Nrf2 in drug resistance.

METHODSTransfecting H460 cells with mKeap1-pEGFP and screenig for Keap1 expressing clones by Western blotting with antibodies against Nrf2, HO-1, NQO1 and AKR1C. The cell line with Keap1 over-expression was further confirmed by real-time PCR. The cytotoxicity of H460-N5 to anti-cancer drugs was evaluated by MTS assay.

RESULTMTS assay results showed the enhanced cytotoxicity of anticancer drugs (Oxaliplatin, Doxorubicin and Etopside) to the H460 cell line with keap1 overexpression compared to the control cell line. In H460-N0 cells, the IC(50) values of Oxaliplation and Etopside were 93 micromol/L and 100 micromol/L respectively whereas the IC(50) values of the two drugs were 42 micromol/L and 30 micromol/L correspondingly in H460-N5 cells. A Nrf2 down-regulated cell line H460-N5 and a control cell line with GFP over-expression have been identified.Down-regulation of Nrf2 enhanced the cytotoxicity of Oxaliplatin, Doxorubicin and Etopside. The IC(50) value of Doxorubicin to H460-N0 cell was above 3 mg/L, but that to H460-N5 cell was about 2 mg/L.

CONCLUSIONA Nrf2 down-regulated cell line H460-N5 and a control cell line with GFP over-expression have been identified. Down-regulation of Nrf2 enhanced the cytotoxicity of Oxaliplatin, Doxorubicin and Etopside.

OBJECTIVETo evaluate the effects of early sufficient resuscitation on important organs function and their therapeutic response in sepsis with hypoperfusion.

METHODSFrom January 2004 to December 2005, 34 sepsis patients with hypoperfusion in surgical and respiratory intensive care units were resuscitated sufficiently for the management of severe sepsis and septic shock. According to the time of resuscitation end points, these patients were divided to early resuscitation group (E group, 15 patients) and later group (L group, 19 patients). The important organs function and their therapeutic response followed resuscitation were investigated and compared in the tow groups.

RESULTSAfter earlier sufficient resuscitation, the incidence of repeated resuscitation was 73.7% in L group and 20.0% in E group (P < 0.01); the incidence of steroids replacement, coagulation dysfunction and multiple organ dysfunction syndrome (MODS) were 63.2%, 73.7% and 68.4% respectively in L group and significantly higher than those in E group (P < 0.05). Seven days after resuscitation, the level of serum creatinine in E group was lower than that in L group (P < 0.05). In the day 1 and 7 after resuscitation, heart rate in E group was lower than that in L group (P < 0.05). Seven days post resuscitation, PaO(2) and PaO(2)/FiO(2) were higher in E group than in L group (P < 0.05). The mortality was 42.1% in L group and 13.3% in E group (P < 0.05).

CONCLUSIONSEarly sufficient resuscitation in sepsis patients with hypoperfusion could significantly enhance the effects of following treatment, relieve inflammation and coagulation reaction and thereby reduce the mortality.
