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.

The regulatory region and the signal peptide sequence of the sacB gene has been amplified by PCR using Bacillus subtilis chromosomal DNA as template, and an inducible secretion vector has been developed based on this sequence, which was ligated with Bacillus subtilis alkaline proteinase gene. Transform Bacillus subtilis DB403 with this vector, and the expression of the inserted Bacillus subtilis alkaline proteinase gene can be induced by addition of sucrose into the medium.

BacKground:Acetic acid spray combined with narrow-band imaging ( NBI ) endoscopy can improve the earIy diagnosis of coIorectaI cancer and precancerous Iesions. Aims:To assess the vaIue of acetic acid spray combined with NBI in diagnosis of earIy coIorectaI cancer and precancerous Iesions. Methods:A totaI of 236 coIorectaI cancer and precancerous Iesions in 180 patients detected by screening endoscopy from Nov. 2011 to JuIy 2013 were enroIIed in this study. Acetic acid spray combined with NBI( combination group),singIe NBI,and indigo carmine staining were used to observe pit pattern,bIood capiIIary forms of the Iesion and mucosa whitening time,and vaIues of the three methods in diagnosis of earIy coIorectaI cancer and precancerous Iesions were evaIuated. Results:Image cIarity of pit pattern in combination group was significantIy improved than that in NBI group and indigo carmine group(χ2 =15. 113,P=0. 000;χ2 =6. 128,P=0. 013);image cIarity of bIood capiIIary forms in combination group was significantIy improved than that in NBI group(χ2 =7. 384,P =0. 007). The overaII coincidence rates of diagnosis in combination group,NBI group, indigo carmine group were 91. 9%,89. 0%,86. 9%,respectiveIy. The diagnosis rate of pit pattern in combination group was significantIy higher than that in NBI group(χ2 =4. 490,P=0. 034),but no significant difference in bIood capiIIary forms was found between combination group and NBI group. The sensitivity of type Ⅲ,Ⅳ,Ⅴ pit pattern,type Ⅱ,ⅢbIood capiIIary forms,mucosa whitening time <30 seconds for diagnosis of coIorectaI cancer and precancerous Iesions in combination group were 94. 0%,92. 8%,92. 2%,respectiveIy,the specificity were 87. 4%,88. 1%,88. 0%, respectiveIy,and the accuracy were 91. 5%,91. 1%,90. 7%,respectiveIy. The sensitivity,specificity and accuracy of type ⅤN or highIy irreguIar ⅤI pit pattern,type ⅢB bIood capiIIary forms and mucosa whitening time 0-5 seconds for predicting invasive carcinoma in combination group were aII quite weII. Conclusions:Acetic acid spray combined with NBI can cIearIy show the pit pattern and bIood capiIIary forms of earIy coIorectaI cancer and precancerous Iesions,and is fairIy consistent with the pathoIogicaI diagnosis. It is heIpfuI for diagnosing the nature of Iesion and depth of invasion.

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.
