BACKGROUND: Many studies have suggested that angiotensin-converting enzyme inhibitors(ACEI) protect blood vessels through anti-atherosclerosis independent of lowering blood pressure, but its mechanism is still unclear.OBJECTIVE: To investigate the anti-atherosclerotic mechanism of ACEI by observing the effects of Enalapril on lipoprotein(a) and oxygen free radicals in patients with acute myocardial infarction (AMI) .DESIGN: A controlled study based on the observation of the patients with AMI.SETTING: Second Department of the South Building, General Hospital of Chinese PLAPARTICIPANTS: Thirty-five inpatients with AMI(19 males and 16 females, aged 42 -75 years old, and averaged (62 ± 9) years old and hospitalized at the Department of Cardiology of Tianjin Harbor Hospital from April 2001 to August 2002 were chosen. These patients were randomly divided into 2 groups: the therapeutic group(20 cases) and the control group(15cases). Inclusion criteria: the diagnosis of patients with AMI was confirmed by WHO criteria. Exclusion criteria: patients with renal dysfunction, shock,hypotension, a history of allergy to ACEI, and a history of severe cough induced by ACEI. All patients had not taken ACEI in the past 2 weeks and agreed to participate in this study.METHODS: On early morning of the third day after AMI, patients in the treatment group took 5 mg of Enalapril one time. If they had no first-dose reaction of hypotension, on the fourth day after AMI, the patients of the treatment group were given a dose of 5 mg twice per day for the following 2 weeks. Then, they were given the drug at a dose of 10 mg twice per day for 2 weeks. The patients in the control group were not given Enalapril. Blood samples were taken respectvely prior to the administration and 2 weeks and 4 weeks after the administration in the two groups. Serum content of lipoprotein(a), oxygen free radicals, triglyceride, total cholesterol, high density lipoprotein(HDL) cholesterol, Apo(a) were measured.MAIN OUTCOME MEASURES: We compared the level of serum of lipoprotein (a), oxygen free radicals (OFR), triglyceride, total cholesterol,HDL cholesterol, Apo(a) pre-treatment and post-treatment respectively in patients of the two groups.RESULTS: Serum levels of OFR were significantly lowered in the treatment group, which were(1 423.14±216.23), (1 076.62±287.12) and (566.57 ± 138.02) U/mL respectively 2 weeks and 4 weeks before and after the treatment(t =2. 937, 3. 571, P ＜0. 01), but there were no significant changes in serum concentrations of lipoprotein(a) and lipids( P ＞ 0.05) .CONCLUSION: Enalapril improved the prognosis of patients with AMI by antioxidation, but not by lowering the serum levels of lipoprotein(a) and lipids. The study can serve as a theoretical reference that the mechanism of Enalapril might inhibit atherosclerosis in patients with AMI.

Objective To systematically review the efficacy and safety of postoperative radiotherapy and postoperative chemotherapy for patients with endometrial cancer,which may give support for clinical proper selection.Methods The randomized controlled trials (RCTs)comparing postoperative radiotherapy with post-operative chemotherapy for patients with endometrial cancer were searched in EMBase,PubMed,Cochrane Library,Chinese Biomedical Literature Data,China National Knowledge Infrastructure,and VIP database from the inception to August 201 5.Two reviewers independently assessed the quality of included studies and extrac-ted data.We analyzed the statistic data using RevMan 5.1 software.Results Three RCTs concluding 1 1 21 patients were included.Meta analysis showed that there were no significant differences between the two groups in five-year survival rate (RR =0.94,95%CI:0.80-1 .1 0,Z =0.77,P =0.440),five-year progression-free survival rate (RR =0.98,95%CI:0.90-1 .07,Z =0.52,P =0.61 0)and recurrence rate (RR =1 .06, 95%CI:0.91 -1 .24,Z =0.75,P =0.450),but there were significant differences between the two groups in grade 3-4 thrombocytopenia (RR =0.1 3,95%CI:0.07-0.27,Z =5.62,P <0.000 01 )and grade 3-4 neu-tropenia (RR =0.01 ,95%CI:0.00-0.03,Z =8.27,P <0.000 01 ).Subgroup analysis showed that there were significant differences between the two groups in five-year survival rate (RR =0.79,95%CI:0.68-0.91 , Z =3.1 5,P =0.002)and five-year progression-free survival rate (RR =0.82,95%CI:0.69-0.97,Z =2.31 ,P =0.020)for patients with Ⅲ-Ⅳ stage endometrial cancer.Conclusion Current evidence indicates that compared with postoperative radiotherapy,postoperative chemotherapy may improve the survival rate for pa-tients with advanced stage endometrial cancer.The long-term curative effects still need to be confirmed by RCTs with high quality and large sample.

Objective To explore clinical effect of the stellate ganglion block combined buflomedil in the treatment of vertebral artery type of cervical syndrome (CSA).Methods One hundred and twenty cases of CSA were included in the study,and randomly divided into two groups.Study group (60 cases)patients were treated by stellate ganglion block therapy combined with buflomedil intravenous;the controlled group (60 cases)was treated with buflomedil intravenous therapy only.In the treatment,vertebral-basi-lar artery mean flow velocity (Vm)was measured before and after treatment and comparison of Vm difference was the clinical ba-sis.According to the CSA standard of clinical cure,the clinical curative effect was observed.Results After treatment,the total ef-fective rate of study group was 95.00%,total effective rate of control group was 71.67%,the difference statistically significant (χ2 =24.474,P <0.05).vertebral artery blood flow velocity of the two groups after treatment increased more obvious than that of before treatment,the difference was statistically significant (P <0.05),vertebral artery blood flow velocity after treatment of study group (38.44±2.20)cm/s was significantly higher than that of the control group (34.36±3.50)cm/s,the difference was statisti-cally significant (t=7.645,P <0.05).basilar artery blood flow velocity of the two groups after treatment increased more obvious than that of before treatment,the difference was statistically significant (P <0.05),basilar artery blood flow velocity after treat-ment of study group(56.34±4.10)cm/s was significantly higher than that of the control group (47.69±3.90)cm/s,the differ-ence was statistically significant (t= 11.841,P <0.05).Conclusion The clinical efficacy of stellate ganglion block combined bu-flomedil in treatment of vertebral artery type of cervical syndrome is obvious.The cure rate with respect to the drug treatment has significant advantages and the therapy is worthy of further promotion.

Objective To investigate the effect of acidic serine protease ASPNJ on the expression of heat shock protein HSP90, 60 and 27 in human chronic myeloid leukemia K562 cells, in order to reveal the related mechanism of anti leukemic effects of ASPNJ. Methods K562 leukemia cell lines were cultured in vitro and treated with ASPNJ alone or in combination with chemotherapeutic agents. Western blot and RT-PCR were used to detect the changes of HSP90, 60 and 27 gene expressions in levels of total protein and membrane protein, as well as in mRNA levels. Results ASPNJ showed different effects on the expression of HSPs in total protein and membrane protein levels and had some modified effect on HSPs in total protein or membrane protein levels. Effects of ASPNJon expression of HSPs mRNA were not apparent, but HSPs mRNA were apparently lower in the ASPNJ and doxorubicin combination group than that in the ASPNJ alone or doxorubicin alone groups. Conclusion The mechanism of ASPNJ on the inhibitory effect of leukemia cells proliferation and the promoting effects on chemotherapeutic drugs may involve some complicated correlations with the effect of ASPNJ on the expression of HSPs and the modification of HSPs proteins.

Objective To investigate the effect of stellate ganglion block ( SGB ) on early postoperative cognitive function in elderly patients undergoing orthopedic surgery .Methods 115 elderly patients with orthopedic surgery were selected as study objects ,and they were randomly divided into observation group (55 cases) and control group(60 cases) according to the digital table .The observation group received epidural anesthesia after SGB ,while the control group only received routine epidural anesthesia .Preoperation and postoperative 6h,3d and 7d,the mini mental state examination ( MMSE ) scores were measured and compared , the cognitive function was assessed .The MMSE score and postoperative cognitive dysfunction ( POCD) occurrence before and after surgery in the two groups were compared.Results In the observation group,the preoperative MMSE score was (29.36 ±2.54) points,the MMSE scores of 6h,3d and 7d after operation were (22.69 ±3.01) points,(25.33 ±2.69) points,(28.32 ± 3.04)points,respectively.The difference between preoperation and postoperation was statistically significant ( F =51.26,P <0.05).In the control group,the MMSE scores of before surgery and 6h,3d,7d after surgery were (29.69 ±2.17)points,(20.24 ±3.59)points,(21.87 ±2.02)points and (27.66 ±3.07)points,respectively,the difference was statistically significant (F=103.70,P<0.05).Before surgery,the MMSE score between the observa-tion group and control group had no statistically significant difference .6h and 3d after surgery,the MMSE scores of the observation group were higher than those of the control group (t=3.947,7.745,all P<0.05);7d after operation,the MMSE score between the two groups had no statistically significant difference (P>0.05).6h after surgery,the inci-dence rate of POCD of the observation group was 3.64％,which of the control group was 11.67％.3d after operation, the incidence rate of POCD was 1.82％ in the observation group and 3.33％ in the control group.There was no statistically significant difference in the incidence of POCD between the two groups at 6 and 3d after operation ( P>0.05).7d after operation,POCD was not detected in the observation group ,and the incidence rate of the control group was 3.33％.The total incidence rate of POCD was 5.45％ in the observation group and 18.33％ in the control group,and the incidence rate of the observation group was lower (χ2 =4.452,P<0.05).Conclusion SGB can improve the cognitive function of elderly patients after orthopedic surgery ,and it is worthy of clinical recommendation .

Objective To investigate the baseline independent prognostic factors for 24 months survival of hepatitis B virus (HBV)-associated acute-on-chronic liver failure (ACLF) patients treated with telbivudine.Methods The prospective cohort study was conducted in HBV-associated ACLF patients who were hospitalized in Mengchao Hepatobiliary Hospital of Fujian Medical University and volunteered to be treated with telbivudine for more than 24 months.The patients were observed for survival at month 1,3,6,12,and 24 after treatment.The baseline biochemical index,coagulant function,model for end-stage liver disease (MELD) score,HBV DNA level as well as comorbidities were analyzed in this study.The count data were compared with kappa test or Fisher's exact test.For the normal distributed measurement data,the homogeneity test of variances (Levene test) was firstly used for comparison between groups.Further,the group t test was applied for variance homogeneity,while the approximate t test was applied for variance non-homogeneity and the Mann-Whitney U test was applied for the non-distributed measurement data.Results A total of 41 patients were enrolled,including 3 drop-outs and 38 accomplishments.Among these 38 patients,there were 3 females (7.9 ％) and 35 males (92.1％),with ages (38.5 ± 11.1) years.There were 32 patients alive and 6 dead during 1 month's follow-up,while baseline MELD score was the independent prognostic factor (RR=1.864,95％CI:1.151-3.019) for survival.There were 31 patients alive and 7 dead during 3 months' follow-up,while baseline MELD score and upper gastrointestinal hemorrhage (UGH) were the independent prognostic factors (RR =2.053,95％CI:1.163-3.625;RR=394.939,95％CI:1.880-82 948.817).There were both 26 patients alive and 12 dead during 6 and 12 months' follow-up,while baseline MELD score was the independent prognostic factor (RR=1.761,95％ CI:1.230-2.523).At the end of 24 months' follow-up,there were 15 patients alive and 23 dead.Viral rebounds were observed in 6 patients and 3 of them were dead.Baseline HBV DNA level,MELD score and electrolyte imbalance were the independent prognostic factors (RR-9.722,95％ CI:1.607-58.821;RR=l.518,95％ CI:1.066-2.162;RR=87.505,95％ CI:2.263-3 384.232) for 24 months'survival.Conclusions Although telbivudine is not recommended as the first-line treatment,ACLF patients with low MELD score and low HBV DNA level at baseline,individualized treatment may improve patient's survival rate.UGH and electrolyte imbalance may affect the efficacy of telbivudine and reduce the survival rate of ACLF patient.
