Objective To explore the effects oflosartan on brain natriuretic peptide(BNP)and C-reactive protein(CLRP)in diabetic cardiomyopathy patients. Methods Sixty diabetics were divided into diabetic control group(30 cases)and diabetic cardiomyopathy group(30 cases), and the levels of BNP and CRP in plasma were determined. Then, diabetic cardiomyopathy group were divided into conventional treatment group(15 cases)and losartan treatment group(15 cases)by random digits table to take corresponding treatment for 12 weeks. The changes of cardiac function, the levels of BNP and CRP in plasma were detected and compared. Results The levels of BNP and CRP in diabetic cardiomyopathy group [(331.27 ±65.64)ng/L,(26.10±10.13)mg/L]were significantly higher than those in diabetic control group[(76.09±39.14)ng/L,(7.03±2.71)mg/L](P＜0.01). After treatment 12 weeks, the levels of BNP and CRP were significantly lower, left ventricular ejection fraction was significantly higher and left ventricular end-diastolic diameter was significantly lower in losartan treatment group than those in conventional treatment group(P＜0.05).Conclusions The increasing levels of BNP and CRP can reflect clinical severity of diabetic cardiomyopathy.Losartan can decrease the levels of BNP and CRP, and improve heart function, and it has better effective on diabetic cardiomyopathy.

Purpose:To evaluate the efficacy and toxicity of vindercine(VDS)in the interven- tional treatment of hepatic and pulmonary carcinomas.Materials and Methods:30 cases of mid-ad- vanced hepatic and pulmonary carcinomas,among them,13 eases of primary hepatic carcinomas,7 cases of matastic hepatic carinomas and 10 cases of primary pulmonary carcinomas,were treated by selective arterial infusion chemotherapy.The combination chemotherapeutic regimens conpored of VDS together with 5-Fu,MMC,carboplatin or Vp16.Results:The response rate for all cases was 60%,for primary hepatic carcinomas 61.5%,for metastic hepatic carcinoma 42.9% and for primary pulmonary carcinoma 70%.Myelosuppession was the main toxicity and 70% patients had the gastrointertional reac- tions as nusea,vomiting etc.Conclusion:VSD is a more effective drug for pulmonary carcinoma,but for hepatic carcinoma,the efficacy of VDS was unmarkable from other drugs.

Objective:To study the expression of caspase-3 and free radical injury in hypoxic-ischemic brain damage ( HIBD) of neonatal rats.Methods:All seven-day-old Wistar rats were randomly divided into HIBD group and sham operation group.Brains was obtained at time of 6 h,12 h,24 h,48 h,72 h,96 h after HIBD.Neuronal cell apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP-biotin nick end labeling ( TUNEL).The expression level of caspase-3 protein was detected by immunohisto-chemistry.The level of malondialdehyde ( MDA) and supemxide dismutase ( SOD) were measured by thiobarbitic acid colorimetry and xanthin oxidase,respectively.Results:The number of neuronal cell apoptosis and the expression of caspase-3 protein began to increase at 6 h and reached the peak at 48 h in HIBD group,they were both significantly higher than those in the sham operation group at each time point (P<0.05).The level of MDA began to increase at 6 h and reached the peak at 24 h in HIBD group,it was significantly higher than the sham operation group at each time point (P<0.05).The level of SOD began to decrease at 6 h and reached the lowest level at 24 h in HIBD group,it was significantly lower than the sham operation group at each time point ( P<0.05 ) .The number of neuronal cell apoptosis and the expression of caspase-3 protein were positively correlated with the level of MDA, but they were negatively correlated with the level of SOD.Conclusion: Free radical injury promotes the expression of caspase-3 and neuronal cell apoptosis in HIBD.

Objective To evaluate the cardiopulmonary allograft function and to analyze key factors for long-term survival of heart-lung transplantation in a patient survived more than 5 years. Methods On December 17th, 2003 at Zhongshan Hospital of Fudan University, a homologous heart-lung transplantation was performed on a female who diagnosed with cardiopulmonary failure secondary to congenital atrial septal defect with severe pulmonary hypertension. Heart-lung allograft was preserved with 1 000 mL UW solution and 4 000 mL HTK solution.Postoperative immunosuppressive therapies were managed with Zenapax, cyclosporine A (or tacrolimus), mycophenolate mofetil and corticosteroids. Cyclosporine A maintained with serum trough levels of 100-200 μg/L and tacrolimus with serum trough levels of 8-20 μg/L. Cardiopulmonary allograft functions were evaluated by echocardiogram, pulmonary function test and thoracic CT periodically. Results The patient survived operation and experienced normal daily life with NYHA cardiac function of class Ⅰ-Ⅱ during the follow-up of 5 years and 6 months. Echocardiogram showed left ventricular ejection fraction of 65% to 86%. Pulmonary function test exhibited with nearly normal oxygen exchange, meanwhile, small airway obstruction was detected from one year after operation and keeping stable from then on. Two episodes of severe pneumonia were complicated and treated with antibiotics and fhconazob, no severe acute allograft rejection episode was experienced. Conclusions Heart-lung transplantation proves to be a reliable therapy modality for terminal cardiopulmonary failure. Excellent donor organ preservation, accurate balance of the risk between acute allograft rejection and infection, and strict preventive measures against infection are key factors for long-term survival of heart-lung transplantation.

A method for determination of PCDD/Fs, PCBs and PCNs in soil sample was developed by using accelerated solvent extraction (ASE)-silica gel column cleanup-basic alumina column separation coupled with GC-MS/MS.The sample was extracted by ASE with Hexane-methylene chloride (Hex-DCM, 50∶50, V/V) at 120℃.The basic alumina column was used to separate PCDD/Fs, PCBs and PCNs.The extracts were eluted with Hex-DCM (95∶5, V/V) to obtain PCBs and PCNs, followed by Hex-DCM (50∶50, V/V) to obtain PCDD/Fs.The limits of detection (LOD) were in the range of 0.04-0.25 μg/L, 0.10-0.20 μg/L and 0.01-0.05 μg/L for PCDD/Fs, PCBs, PCNs, respectively.The relative standard deviations (RSDs) of average relative response factors (RRF) were below 13%.The recoveries of 13C-labeled internal standards of the three classes of analytes were 50%-95%, 51%-103% and 49%-74%, respectively.Concentrations of ∑PCDD/Fs, ∑PCBs and ∑PCNs in soil samples were 16.1-1148 pg/g, 6.6-152.6 pg/g and 10.9-99.5 pg/g, respectively.The results were consistent with that of high resolution mass spectrometer.

Objective The aim of this study was to evaluate of adilty of two acute renal failure-specific scoring systenms (the classification by Bellome et al and the AKIN criteria) for predicting hospital mortality after cardiac surgery in adult patients. Methods Between October 1 st 2006 to Decemjber 31 st 2006, 509 adult patients who ungerwent coronary artery bypass grafting (CABG) and/ or valve operation were enrolled in this study. The medical data collection included gender, age, types of operation, perioperative he- modynamic parameters, urine output, biochemical parameters and outcome. Renal function was assessed daily according to the classi- ficatinn by Bellomo and the AKIN criteria, respectively. As references, Acure Physiology and Chronic Health Evaluation(APACHE) Ⅱ and Sepsis-related Organ Failure Assessment (SOFA) score were also calculated. Resuits Three hundred and forty-one patients were male (67.0%), and 168 were female (33.0%), mean age was (56.2±12.0) years old. Tnree hundred and nine patieats un- derwent CABG, 182 underwent valve operation and 18 underwent CABG plus valve operation, Mean duration of ventilation support was (20.4±17.7) houra, and the ICU stay was (1.4±1.0) days. Postoperative hospital stay was (13.8±9.1) days. According to the classification by Bellomo., the highest in-hospital mortality was 52.9% in ARFS group. Mahiplicatinn of in-hospital morality rate was abserved (X2 for trend, P<0.01) in 0.4% (non-ARF), 1.2% (stage 1), 12.0% (stal～ 2) and 32.4% (stage 3) of pa- tients based on the AKIN criteria. By applying the area under the receiver operating characteristic ourve, the classification by Bellomo and the AKIN criteria had good discriminative power. Furthering, multivariate logistic regression analysis verified that the Odds Ratio of the AKIN criteria was 5.478 (P =0.028, 95% Confidence Interval 1.027- 24.856), after adjusting for gender and age. Con- clusion Analytical data confinned good discriminative power of both the AKIN criteria and the classification by Bellomo for predicting hospital mortality of adult postoperative patient with ARF.

Objective To study the influencing factors for outcomes of gastric low-grade intraepithelial neoplasia ( LGIN) for better LGIN treatment regimen. Methods Using magnifying endoscopy combined with narrow-band imaging ( ME-NBI ) follow-up strategy, the endoscopic features of 47 cases of LGIN in Fujian Provincial Hospital, including location, size, surface situation, demarcation line, microvascular pattern and microsurface pattern, were prospectively observed, then the factors influencing the outcome were analyzed. Results Among the 47 cases of LGIN, there were 35 cases in stable condition, whose results of biopsy and ME-NBI had no changes (stable LGIN), and the mean follow-up time was 20. 7±6. 9 months. The remaining 12 patients had progressive dysplasia (progressive LGIN), including 4 cases of high-grade intraepithelial neoplasia, and 8 cases of moderate dysplasia. The mean follow-up time was 16. 3 ± 11. 8 months. There were no significant differences between the two groups in gender (P=0. 33), mean age (P=0. 13), lesion distribution (P=0. 70), and lesion morphology (P=0. 97). The lesion size was less than 20 mm in the stable group ( 71. 4％, 25/35) , and over 20 mm in the progressive group ( 66. 7％, 8/12) , and the difference was statistically significant ( P=0. 02) . The proportion of the lesion surface heterogeneity in the progressive group was significantly higher than that in the stable group[75. 0％ (9/12) VS 34. 3％ (12/35),P= 0. 01 ] . The proportion of positive manifestations under ME-NBI in the progressive group was also significantly higher than that in the stable group [ 83. 3％ ( 10/12 ) VS 8. 6％ ( 3/35 ) , P = 0. 00 ] . Conclusion The size of lesions over 20 mm, the uneven surface and positive ME-NBI are the important factors influencing the outcome of LGIN, which are of significance for the diagnosis and treatment of LGIN.

Objective To investigate the correlation between decoy receptor (DcR) 1,DcR2,osteoprotegerin (OPG) gene polymorphisms and susceptibility of Crohn's disease (CD) in Han population in Zhejiang province.Methods From April 2008 to July 2017,at the Department of Gastroenterology of The Second Affiliated Hospital of Wenzhou Medical University,The First Affiliated Hospital of Wenzhou Medical University,Central Hospital of Wenzhou and Renmin Hospital of Wenzhou,285 patients diagnosed as having CD were enrolled,and during the same period 572 healthy individuals who received health checkup at the Second Affiliated Hospital of Wenzhou Medical University were collected as healthy control.The single nucleotide polymorphism (SNP) of DcR1 (rs12549481),DcR2 (rs1133782) and OPG (rs3102735) were examined by SNaPshot technique.An unconditional logistic regression analysis was performed to analyze the differences in each SNP mutation alleles and genotype frequencies between CD group and control group.Furthermore,their correlation with clinicopathological features of CD and the efficacy of corticosteroid and infliximab was also evaluated.Results The frequencies of mutant allele A and genotype GA + AA of DcR2 (rs1133782) of CD group were 11.93％ (68/570) and 22.81％ (65/285),respectively,which were higher than those of healthy control group (8.22％,94/1 144;and 15.91％,91/572;odds ratio (OR) =1.513,95％ confidence interval (CI) 1.088 to 2.104,P =0.013;OR =1.562,95％ CI 1.094 to 2.230,P =0.014).However there was no statistically significant difference in the mutant allele and genotype frequencies of DcR1 (rs12549481) and OPG (rs3102735) between two groups (all P ＞ 0.05).The frequencies of mutant allele C and genotype TC + CC of DcR1 (rs12549481) in patients with stricturing CD were 13.89％ (25/180)and 27.78％ (25/90),respectively,which were lower than those of patients with non-stricturing,non-penetrating CD (27.68％,62/224 and 48.21％,54/112),and the differences were statistically significant (OR =0.421,95％ CI 0.252 to 0.705,P =0.001;OR =0.413,95％ CI 0.229 to 0.747,P =0.003).Besides,the frequencies of mutant allele A and genotypes GA + AA of DcR2 in patients with penetrating CD were 7.23％ (12/166) and 13.25％ (11/83),which were lower than those of patients with non-stricturing,non-penetrating CD (15.62％,35/224 and 30.36％,34/112),and the differences were statistically significant (OR =0.407,95％ CI 0.205 to 0.809,P =0.009;OR =0.350,95％ CI 0.165 to 0.743,P =0.005).In addition,there was no statistically significant difference in the frequencies of mutant allele and genotypes of OPG (rs3102735) among subtypes of CD with different features (all P ＞ 0.012 5).Moreover,the DcR1 (rs12549481),DcR2 (rs1133782) and OPG (rs3102735) polymorphisms were not correlated with the efficacy of corticosteroid and infliximab (all P ＞ 0.05).Conclusions DcR1 (rs12549481) mutation may be correlated with stricturing CD.DcR2 (rs1133782) mutation may be correlated with CD,especially with penetrating CD.However,the gene polymorphism of OPG (rs3102735) is not correlated with the risk of CD susceptibility.And the above gene SNP may be independent of the efficacy of corticosteroid and infliximab.

Objective To investigate ultrahistopathological features of symmetrical acrokeratoderma.Methods Biopsy specimens were obtained from skin lesions and perilesional normalappearing skin of 6 patients with symmetrical acrokeratoderma,as well as from normal skin of 3 healthy volunteers.Then,these skin specimens were subjected to transmission electron microscopy (TEM).Results TEM showed obviously thickened stratum corneum,irregular morphology of keratinocytes and discontinuous cornified envelope.Aggregation and abnormal arrangement of keratin filaments occurred in all epidermal layers.Many vacuoles of different sizes were observed in the transitional zone between the stratum corneum and stratum granulosum.Hypogranulosis,abnormal shape and different sizes of keratohyalin granules,and reduction of membrane-coating granules were found in the stratum granulosum.Increased melanocytes with a large number of stage Ⅳ melanosomes in the cytoplasm were observed in the basal layers.Moreover,there was infiltration of a few lymphocytes in the superficial dermis.Perilesional normal-appearing skin tissues showed similar but milder ultrastructural changes.Conclusion Abnormal metabolism of keratins,epidermal differentiation complex proteins and lipids may exist in skin lesions of symmetrical acrokeratoderma,which may contribute to epidermal thickening and impairment of skin barrier function.
