OBJECTIVETo investigate the effect of intralipid on protein consumption in severe burned patients. METHODS; Sixty-seven nonoperative patients with severe burns were divided into Intralipid treatment group and non-intralipid treatment group (control group), and the former was treated with 20% intralipid (500 ml once a day) from postburn day 4 for 10 consecutive days. Venous blood samples were collected from these patients for testing total protein, albumin, total cholesterol and triglyceride on postburn days 1, 7 and 14, respectively.

RESULTSThe levels of total protein, albumin, total cholesterol and triglyceride were within normal range on postburn day 1 in both groups, and only the albumin level was lowered in the groups on day 7 but at comparable magnitudes (32+/-4.83 vs 31+/-5.04 g/L, P<0.05). In contrast, the levels of total protein, albumin, total cholesterol and triglyceride were below the normal range on postburn day 14 in both groups, but intralipid treatment group showed more albumin loss than the control group (28+/-6.46 vs 23+/-7.03 g/L, P<0.01).

CONCLUSIONIntralipid (20%) provides good energy source to ameliorate albumin loss in severe burned patients.

OBJECTIVETo evaluate the efficacy and safety of acupuncture and moxibustion in the treatment of post-stroke depression (PSD) by regulating the liver and strengthening the root prescription.

METHODSIn light of the random controlled trial principle, 123 cases were randomized into an acupuncture-moxibustion group (42 cases), a medication group (40 cases) and an acupuncture + medication group (41 cases). In the acupuncture-moxibustion group, the therapy of regulating the liver and strengthening the root was applied. Acupuncture was given at Hegu (LI 4), Taichong (LR 3), Baihui (GV 20, Yintang (GV 29), etc. The granule moxibustion was applied at Zhongwan (CV 12), Xiawan (CV 10), Guanyuan (CV 4) and Qihai (CV 6). The treatment was given once a day and stopped in weekend. In the medication group, paroxetine hydrochloride tablets were prescribed for oral administration, 20 mg each day after breakfast. In the acupuncture + medication group, the therapies were adopted as the acupuncture-moxibustion group and the medication group. In the 2nd and 4th week of treatment, HAMD was used as the primary index and Barthel index as the secondary one for the efficacy assessment in the three groups respectively. The spleen and stomach syndrome scale of TCM was used for the assessment of TCM syndrome efficacy. Treatment emergent symptom scale (TESS) was applied for the safety assessment.

RESULTSIn the 4th week of treatment, the markedly effective rates were 69.0% (29/42), 65.0% (26/40) and 70.7% (29/41) in the acupuncture-moxibustion group, the medication group and the acupuncture + medication group respectively. The efficacies of anti-depression were similar in comparison among groups (P > 0.05). In the 2nd week of treatment, the improvement of HAMD score was significant in the acupuncture + medication group as compared with that before treatment and in comparison with the medication group (P < 0.05, P < 0.01). As for improving Barthel index, reducing the spleen and stomach symptom score of TCM and decreasing the score of TESS, the results in the acupuncture-moxibustion group and the acupuncture + medication group were superior to those in the medication group (P < 0.05, P < 0.01).

CONCLUSIONThe therapy of acupuncture and moxibustion with regulating the liver and strengthening the root achieves the definite efficacy of anti-depression and presents the quite high safety in treatment.

BACKGROUND: Fish oil is one of mainly natural resources of n-3 fatty acids, which can inhibit cardiac allograft vasculopathy (CAV) and prolong the survival of cardiac allograft. But, the mechanism is unclear. Recent in vitro data suggested that n-3 fatty acids could inhibit the release of inflammatory transmitter by the activation of peroxisome proliferator-activated receptor-y (PPARy). OBJECTIVE: To test the hypothesis that n-3 fatty acids from fish oil ameliorates CAV development via activating PPARy. METHODS: A total of 6 Lewis rats and 18 Fisher344 rats were randomly selected as heart donors. An additional 24 Lewis rats were randomly and equally divided into 4 groups. In isograft group, heart transplantation was performed among Lewis rats, without any drug. In low-dose fish oil-treated group, F344→Lewis transplantation was performed. At 1 day following surgery, 0.03 mL/kg fish oil was treated by gavage for 8 weeks. In high-dose fish oil-treated group, F344→Lewis transplantation was conducted. At 1 day following surgery, 0.06 mL/kg fish oil was treated by gavage for 8 weeks. In control group, F344→Lawis transplantation was conducted. Cyclosporine A was administrated by gavage for 8 weeks. In the low-dose and high-dose fish oil-treated groups, cyclosporine A (1.5 mg/kg) was given daily by intramuscular injection for 2 weeks following surgery. CAV was evaluated by histological examination. Activity of nuclear factor (NF) k-B and PPARy was assessed in homogenate. Contents of monocyte chemoattractant protein-1 and interferon-inducible protein 10 were measured by enzyme-labeled immunosorbent assay (ELISA). Chemokine receptor CCR2 and CXCR3 expression was determined by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). RESULTS AND CONCLUSION: All 24 receptor Lewis rats were survived following surgery. The donor heart could regularly beat at 8 weeks following transplantation. Compared with the isograft group, severe CAV was detected in the control group al 8 weeks. Compared with the control group, CAV was significantly relieved, the activity of PPARy was significantly elevated, the activity of NF k-B was significantly decreased, levels of intragraft monocyte chemoattractant protein-1 and interferon-inducible protein-10 were significantly reduced in the low-dose and high-dose fish oil-treated groups (P < 0.001, P < 0.05), especially in the high-dose fish oil-treated group (P < 0.05). There was no significant difference in expression of chemokine receptors CXCR3 in the low-dose and high-dose fish oil-treated groups and control group. Our results demonstrated that n-3 fatty acids from fish oil can attenuate CAV development, possibly through activating PPARy and subsequently inhibiting the NF-kB activation, the chemokines secretion and its receptor expression in a dose-dependent fashion in rat models.

Objective To establish real-time PCR with SYBR Green Ⅰ for quantification the gene of survivin.Methods The components and conditions of PCR system were optimally determined by fluorescence intensity,cycle threshold(Ct),melting curve,coefficiency and slope of the standard curve.The means to eliminate the contaminating fluorescence of primer-dimers and the mode for Ct value determination were also optimized.Using the developed PCR system,we quantificated the survivin gene in 43 patients with gastric carcinoma.Results The optimized condition for PCR amplification of survivin were 2 mmol/L of MgCl_2,2.5 U/100 ?l of Taq DNA polymerase,0.2 ?mol/L of primers,and the optimized annealing temperatures for PCR were 58℃.The influence of primer dimmer can be eliminated by setting the fluorescence collecting temperature below the Tm of the specific amplicon by 2℃.The second derivative maximum mode,instead of fit point mode,was a feasible method to determine the Ct value for quantification.The sensitivity of this method was 10 copies/?l,and a good linearity was found from 10~1 to 10~4 copies/?l(r = 0.999 7).The inter-experimental coefficient of variation was 1.13%-1.91%,whereas the coefficient of variation between runs was 3.31%-4.50%.Using the optimized PCR system,we quantificated the gene of survivin,the result indicated that survivin gene was amplified in 13.9% of gastric carcinomas.Conclusions The optimal real-time PCR with SYBR Green Ⅰ,as a cost-effective and feasible DNA quantitative method,is fit for quantification of the survivin with satisfactory repeatability and high sensitivity.

Objective To investigate the relationship between refractory hypertension and renal hemodynamics in end stage renal diseases (ESRD) patients.Methods ESRD patients were classified into:patients with refractory hypertension (group A) and patients with normal blood pressure(group B).Renal hemodynamic indices were ex- amined by duplex ultrasonography.Fasting serum lipid (TC,TG,HDL-C,LDL-C,Lp(a),ox-LDL) and serum parathyroid hormane (PTH) were determined in all patients.Results Significant differences were found in renal hemodynamic indices such as peak systolic velocity (PSV),mean flow velocity (MV),pulsatility index (PI),renal- aortic ratio (RAR) and in clinical index such as Lp(a) and ox-LDL between the two group.Refractory hyperten- sion patients had lower renal hemodynamic indices and higher Lp(a) and ox-LDL levels than in patients with con- trolled BP.Logistic regression analysis revealed that refractory hypertension was related with PSV,EDV,Pl and RAR,but not relevant with sex,age,dialysis time,hematocrit,BUN,creatinine,TC,TG,HDL-C,LDL-C, PTH,MV and RI.Conclusion Atherosclerotic renal artery stenosis and severe disorder in renal hemodynamics is likely the cause for refractory hypertention in ESRD patients.The rise of serum Lp(a) and ox-LDL might acceler- ate renal artery atherosclerosis.

Objective To investigate the characteristics of pulse wave velocity(PWV)and heart rate variability (HRV)and evaluate their feasibility in grading the cardiovascular risk in patients with isolated systolic hypertension (ISH).Methods Eighty-nine ISH patients and systolic-diastolic hypertension patients(DH,n=98)admitted in our hospital were submitted carotid-radial PWV(crPWV),carotid femoral PWV(cfPWV)and HRV,ISH patients were categorized depending on their risk grade as:low risk group(n=3),moderate risk group(n=17),high risk group(n=35)and very high risk group(n=34).Results The cfPWV in ISH patients is significantly higher than that of sys-diastolic hypertension group(ISH: 399.6?48.2 vs sys diastolic hypertension:374.3?39.7 cm/s,P0.05).The LF in ISH group are markedly higher than those in DH(ISH:4.35?1.07 log ms~2 vs 3.78?0.82 log ms~2,P 0.05).LF are markedly positive correlated with the degree of the total cardiovascular risk(rs=0.438,P
