Objective To investigate the myocardial damage in rats fed with corn from Keshan disease area added with bean puree. Methods Male Wistar rats were randomly divided into 3 groups according to their body weights, and fed with corn, corn from Keshan disease area added with bean puree, corn from non-endemic area. The GSH-Px activity of vena cardalis blood was examined in 1 and 3 months, rats were sacrificed after being fed for 6 months to examine the heart changes with HE stain. Results The three groups of GSH-Px activity were different in 1 and 3 months respectively(F=23.60,72.46, all P<0.01); GSH-Px activity was (181.58±22.15), (44.76±28.59)U/L in rats fed with corn, was (195.03±17.66), (30.38±3.35)U/L in those fed with corn added with bean puree from Keshan disease area, lower than the group fed with corn of non-endemic area[(340.90±95.42), (125.17±13.64)U/L, all P < 0.01]. But the difference of GSH-Px activity between simple corn group and corn adding bean puree groups of Keshan disease area was not obvious(P>0.05). Myocardial damage incidence of the three groups was 3/9,1/9,2/7. Difference among three groups did not have statistical significance(χ2=1.33, P> 0.05). Conclusions Only corn from Keshan disease area may induce myocardial damage pathology change. Adding bean puree into corn does not increase damage.

OBJECTIVETo observe therapeutic effect of acupuncture on diabetic peripheral neuropathy (DPN) and explore the mechanism.

METHODSSixty-eight cases of DPN were treated with acupuncture at Jianyu (LI 15), Quchi (LI 11), Waiguan (TE 5) etc. and their blood sugar, blood lipids and hemorrheologic indexes and nerve conductive velocity before and after treatment were determined.

RESULTSAfter treatment, 43 cases were markedly effective, 20 cases were effective and 5 cases were ineffective, with a total effective rate of 92.6%; the nerve conductive velocity, plasma insulin, C-peptide, opioid peptides increased significantly (P<0.01) and blood viscosity significantly decreased (P<0.01).

CONCLUSIONAcupuncture has a definite therapeutic effect on DPN and the increase of nerve conductive velocity is possibly related with the increase of plasma opioid peptides.

OBJECTIVETo study whether hematologic malignancy patients with anemia have a lower erythropoietin (EPO) response.

METHODSSerum EPO levels were detected by ELISA in patients with hematologic malignancies and with iron deficiency anemia (IDA). Eighty patients with hematologic malignancies, including 13 multiple myeloma (MM), 7 chronic lymphocytic leukemia (CLL) and 60 non-Hodgkin's lymphoma (NHL) were studied. Thirty of them had anemia(21 NHL,6 MM and 3 CLL). Twenty patients with IDA were studied as the control.

RESULTSHematologic malignancy patients with anemia had higher EPO levels [(97.8 +/- 183.9) IU/L] than those with normal Hb values [(27.8 +/- 85.4) IU/L; P <0.01]. In patients with IDA, serum EPO response was inversely correlated with Hb level (r= -0.5, P <0.05) , but no such inverse correlation was found in the hematologic malignancy patients with anemia (r = -0.14). After corrected for Hb level, the serum EPO levels were significantly lower in anemic patients with hematologic malignancies than in IDA patients (P = 0.032) , indicating a decreased EPO response in the former group.

CONCLUSIONAnemia associated with hematologic malignancy might result from an inappropriately low EPO response. EPO treatment for these patients may be beneficial.

OBJECTIVETo study the temporal trend and spatial distribution of premature mortality burden due to chronic obstructive pulmonary disease (COPD) in terms of years of life lost (YLL) in an urban region of Kunming for the years 1998-2003.

METHODSPan Long district was selected as the study region. YLL was used to measure premature mortality burden due to COPD. The tate of YLL per 1000 residents was calculated without age-weighting but with 3% discounting rate and broken down by year. Geographic information system (GIS) technique was used to display the spatial distribution of premature mortality burden due to COPD during the six years of study.

RESULTSDuring the years from 1998 to 2003, the premature mortality burden due to COPD decreased by years while males seemed to have a higher YLL rate of COPD than females. Central areas remained to have higher YLL/1000 population values of COPD for the six years, whereas remote areas tended to have a decreasing trend of YLL/1000 population values of COPD in the same period.

CONCLUSIONCentral areas of the city should be emphasized in further control of COPD in the urban region of Kunming.

Objective To investigate expression and significance of decorin(DCN)in liver tissue and serum of liver transplant patients with chronic rejection(CR).Methods Immunohistochemistry(SP method)was used to detect expression of DCN in liver tissue of 16 normal controls, 20 patients with cirrhosis, 46 liver translantion patients without CR and 8 patients with CR.Enzyme-linked immunosorbent assay method(ELISA method)was used to determined the content of DCN in serum of all research subjects.Results The expression of DCN was negative in normal hepatic tissues and with/without CR, cirrhosis tissues showed strong expression of DCN.The positive expression rate and the average optical density value of DCN in liver transplant tissues with CR had significant difference comparing with Cirrhosis tissues(25% vs 55%, 0.1249 ±0.0039 vs 0.2357 ±0.0396, P <0.01,while no statistic siqnificance compared to normal liver tissues and those without CR.The level of DCN in serum was significantly higher in liver transplant patients with CR, with significant difference comparing with normal people, liver cirrhosis and transplant liver patients without CR(54.0833 ± 6.0325)μg/L vs(1.0232 ± 0.9105)μg/L,(12.6202 ± 1.5370)μg/L,(17.7102 ± 2.3562)μg/L, P < 0.01).The concentration of DCN in serum showed a positive correlation with the degree of CR.Conclusions DCN showed negative expression in liver tissue and increased significantly in serum of liver transplantation patients with CR.This suggests that DCN may be involved in occurrence and development of CR.At the same time the determination of DCN in serum maybe become an important indicator of the early diagnosis, development and prognosis of CR for liver transplant patients.

BACKGROUND: Acute liver failure (ALF) caused by viral and non-viral hepatitis is often accompanied with severe metabolic disorders, the accumulation of toxic substances and continuous release and accumulation of a large number of endogenous toxins and inflammatory mediators. The present study aimed to investigate the effects of various combined non-biological artificial liver treatments for patients with acute liver failure (ALF) complicated by multiple organ dysfunction syndrome (MODS). METHODS: Thirty-one patients with mid- or late-stage liver failure complicated by MODS (score 4) were randomly divided into three treatment groups: plasmapheresis (PE) combined with hemoperfusion (HP) and continuous venovenous hemodiafiltration (CVVHDF), PE+CVVHDF, and HP+CVVHDF, respectively. Heart rate (HR) before and after treatment, mean arterial pressure (MAP), respiratory index (PaO2/FiO2), hepatic function, platelet count, and blood coagulation were determined. RESULTS: Signifi cant improvement was observed in HR, MAP, PaO2/FiO2, total bilirubin (TBIL) and alanine aminotransferase (ALT) levels after treatment (P<0.05). TBIL and ALT decreased more signifi cantly after treatment in the PE+CVVHDF and PE+HP+CVVHDF groups (P<0.01). Prothrombin time (PT) and albumin were signifi cantly improved only in the PE+CVVHDF and PE+HP+CVVHDF groups (P<0.05). TBIL decreased more significantly in the PE+HP+CVVHDF group than in the HP+CVVHDF and PE+CVVHDF groups (P<0.05). The survival rate of the patients was 58.1％ (18/31), viral survival rate 36.4％ (4/11), and non-viral survival rate 70％ (14/20). CONCLUSION: Liver function was relatively improved after treatment, but PE+HP+CVVHDF was more efficient for the removal of toxic metabolites, especially bilirubin. The survival rate was significantly higher in the patients with non-viral liver failure than in those with viral liver failure.

X-linked ichthyosis (XLI) is a metabolic disease with steroid sulfatase deficiency and often occurs at birth or shortly after birth. The encoding gene of steroid sulfatase, STS, is located on the short arm of the X chromosome, and STS deletion or mutation can lead to the development of this disease. This study collected the data on the clinical phenotype from a family, and the proband, a boy aged 11 years with full-term vaginal delivery, had dry and rough skin and black-brown scaly patches, mainly in the abdomen and extensor aspect of extremities. Peripheral blood samples were collected from each family member and DNA was extracted. Multiplex ligation-dependent probe amplification (MLPA) was used to measure the copy number of STS on the X chromosome. Whole-genome microarray was used to determine the size of the segment with microdeletion in the X chromosome. MLPA was then used for prenatal diagnosis for the mother of the proband. The results revealed that the proband and another two male patients had hemizygotes in STS deletion. Gene microarray identified a rare deletion with a size of 1.6 Mb at Xp22.31 (chrX: 6,516,735-8,131,442). Two female family members were found to be carriers. Prenatal diagnosis showed that the fetus carried by the proband's mother was a carrier of this microdeletion. This study showed STS gene deletion in this family of XLI, which causes the unique skin lesions of XLI. MLPA is a convenient and reliable technique for the molecular and prenatal diagnosis of XLI.

OBJECTIVETo investigate the effects of human tissue kallikrein 1(Ad-hKLK1) gene delivery on the neointima formation in carotid arteries of spontaneously hypertensive rats (SHRs).

METHODSCarotid artery restenosis was induced in male SHR rats by balloon-injury. Rats were randomly assigned into 4 groups: Sham-operated (n = 6); Angioplasty (phosphate buffered solution 50 microl, n = 8); Vector virus (control virus, 1 x 10(9) IU in 50 microl, n = 8) and Ad-hKLK1(Ad-hKLK1, 1 x 10(9) IU in 50 microl, n = 8). Rats were sacrificed 4 weeks later. The wall-to-lumen area ratio and intima/media ratio in carotid artery were assessed by image analysis in HE stained sections. The mRNA bradykinin receptor (B1R and B2R) expressions were detected by RT-PCR. The protein expression of the cycle-independent kinase inhibitors p27Kip1 and p2lCip1 were determined by Western blot analysis.

RESULTSWall-to-lumen area ratio reduced 35.6% and intima/media ratio reduced 38.8%in Ad-hKLK1 treated SHRs compared to angioplasty group (all P < 0.001). The expression of p27Kip1 and p2lCip1 increased significantly in Ad-hKLK1 treated SHRs compared with angioplasty rats (all P < 0.001). The mRNA expression of B2R was significantly upregulated in angioplasty rats compared with sham-operated rats (P < 0.05) while mRNA expression of B1R was similar between the 2 groups.

CONCLUSIONhKLK1 gene delivery may effectively reduce neointimal formation via downregulating bradykinin B2R and up-regulating the expressions of p27Kip1, p2lCip1 signaling pathways in carotid arteries of SHRs after balloon injury.
