OBJECTIVETo investigate the status of the micro-inflammation in patients undergoing maintenance hemodialysis and the effect of combined therapy with hypha cordyceps and ginkgo leaf tablet for its prevention and treatment.

METHODSSixty-five patients undergoing long-term maintenance hemodialysis were randomly assigned to the treated group (33 patients) and the control group (32 patients). Patients in both groups underwent hemodialysis regularly, meanwhile, 3 capsules of Jinshuibao (each capsule containing hypha cordyceps 0.33 g) and 1 tablet of ginkgo leaf tablet (0.23 g/tablet) were additiolally given to the patients in the treated group orally, 3 times per day, and 3 months as 1 treatment course. Their serum inflammatory factors, such as high sensitive C-reactive protein (hs-CRP), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha), which could reveal the state of microinflammation, were determined before and after treatment. And the same index was also determined in 30 healthy persons allocated in a normal control group.

RESULTSCompared with the normal control group, the serum levels of hs-CRP (4.94 +/- 2.21 mg/L), IL-6 (0.472 +/- 0.220 microg/L) and TNF-alpha (1.748 +/- 0.724 microg/L) in the treated group were higher before treatment, these indexes decreased markedly after treatment (3.28 +/- 1.28 mg/L, 0.379 +/- 0.163 microg/L, and 1.330 +/- 0.458 microg/L, respectively, all P < 0.01), but without significant change in the control group.

CONCLUSIONMicro-inflammation reaction exists popularly in patients undergoing maintenance hemodialysis, and the combined therapy with hypha cordyceps and ginkgo leaf tablet could effectively improve this kind of micro-inflammation reaction.

OBJECTIVETo investigate the diagnosis and treatment of malignant fibrous histiocytoma of the retroperitoneum (MFHR).

METHODSThe clinicopathological features, treatment and prognosis of 31 patients with MFHR were retrospectively analyzed.

RESULTSThe mean age of the patients was 52.7 +/- 14.1 years. Male:Female = 22:9. The primary symptoms were abdominal mass and pain. The average diameter of tumor was 15 cm. The histopathologic types of the tumor were inflammatory, storiform-pleomorphic, myxoid and giant cell in 16, 10, 4 and 1 cases. The overall survival rate of 1-, 3- and 5-year was 61.3% +/- 9.8%, 31.6% +/- 11.3% and 21.1% +/- 11.4% with a median survival time of 17.0 +/- 6.3 months. Complete resection of the tumor was the major prognostic factor. Postoperative radiotherapy of 20 - 45 Gy was able to prolong the median survival from 12.1 +/- 11.6 months of surgery alone to 26.4 +/- 22.0 months of surgery plus postoperative radiotherapy though without statistical significance (P = 0.051). Postoperative CHOP chemotherapy was not shown to be beneficial.

CONCLUSIONChemotherapy remains the important method of cure. The survival in patients with MFHR might be improved by complete resection combined with chemotherapy or/and radiotherapy.

OBJECTIVETo investigate the detrimental effects of hemorrhagic shock on the structure and function of mitochondria DNA (mtDNA) encoding cytochrome oxidase genes in intestinal epithelial cells.

METHODSWistar rats were used and divided into two groups: hemorrhagic shock group and control group. Hemorrhagic shock model of rats was utilized in this experiment. The mtDNA was extracted from the intestinal epithelial cells and amplified by polymerase chain reaction (PCR) with different primers of cytochrome oxidase (COX I, COX II and COX III). The products of PCR were directly sequenced.

RESULTSHemorrhagic shock could result in the point mutagenesis in mitochondrial genome encoding cytochrome oxidase (COX I and COX II). There were 4, 4, 22, 16, 35 point mutations in COX I from 5545 to 6838 bp in 5 shocked rats. There were five point mutations in COX II from 7191 to 7542 bp at the site of t7191c, t7212c, a7386g, a7483g, c7542g in 1 shocked rat. There was no mutation found in COX III.

CONCLUSIONSHemorrhagic shock could significantly induce the damage of the gene of cytochrome oxidase encoded by mtDNA.

OBJECTIVETo investigate the effects of seawater immersion on the function of myocardium and hepatocyte mitochondria in experimental hemorrhagic shock rats.

METHODSTwenty-four male Wistar rats were divided into three groups (n=8 in each group): control group, HSL group (hemorrhagic shock group on land) and HSS group (hemorrhagic shock group in seawater). The hemodynamic parameters, activities of H(+)-ATPase (adenosinetriphosphatase), succinate dehydrogenase (SDH) and Ca(2+)-Mg(2+)-ATPase, the calcium contents in myocardium and hepatocyte mitochondria were measured and the changes of proton translocation across the inner mitochondrial membrane were analyzed.

RESULTSThe hemodynamic indexes and the activities of H+-ATPase, SDH, Ca(2+)-Mg(2+)-ATPase in HSS group were significantly lower than those in control group and HSL group (P<0.05). In HSS group the calcium levels in tissue and mitochondria of myocardium and hepatocyte were elevated significantly compared with control group and HSL group (P<0.05). There was no significant difference in proton translocation among three groups.

CONCLUSIONSThis investigation demonstrates that seawater immersion can aggravate the conditions of hemorrhagic shock rats.

OBJECTIVETo investigate the changes of proton transportation across the inner mitochondrial membrane (IMM) and H(+)-ATPase of hepatocytes in endotoxic shock rats.

METHODSEndotoxin from E. Coil of 5.0 mg/kg or saline of 1 ml/kg was injected into the femoral vein. The rats were sacrificed pre-injection and 1, 3, 5, 8 hours after injection, and plasma and liver tissue samples were collected respectively. The liver tissue samples were used for preparation of mitochondria and submitochondrial particles (SMPs). The proton-translocation of SMPs and H(+)-ATPase, phospholipase A(2) (PLA(2)) activities and malondialdehyde (MDA) content, membrane fluidities of different level of mitochondria membrane and plasma MDA content were assayed.

RESULTS(1) Five hours after E. Coli. O111B4 injection, the maximum fluorescence quenching ACMA after adding ATP, nicotinamide adenin dinucleoacid hydrogen (NADH), and the succinate were significantly decreased (P<0.05). The time of maximum fluorescent quenching and the half time of fluorescent quenching were significantly prolonged (P<0.01), especially when NADH was used as a substrate. (2) The mitochondrial H(+)-ATPase activity was significantly increased at early stage of endotoxic shock (P<0.05), and significantly decreased at late stage of endotoxic shock (P<0.01). (3) The mitochondrial membrane bound PLA(2) activity, plasmal and mitochondrial MDA content were significantly increased and succinate dehydrogenase (SDH) activity of mitochondria decreased markedly in endotoxic shock rats (P<0.05). (4) The mitochondrial membrane fluidity of different lipid regions was decreased, especially in the head of phospholipid.

CONCLUSIONSProton transportation across IMM and mitochondrial H(+)-ATPase activity are significantly decreased in endotoxic shock.

OBJECTIVETo investigate the expression and its clinical significance of estrogen receptor (ERα) and phosphorylated estrogen receptor (p-ERα) in patients with hepatocellular carcinoma. The associations between ERα, p-ERα and IL-6 were also analyzed.

METHODSImmunohistochemistry was used to detect the expression of ERα, p-ERα and IL-6 in tumor tissues from 77 cases with hepatocellular carcinoma. The relations between ERα and the clinical pathological parameters and prognosis were also analyzed.

RESULTSThe positive rates of ERα, p-ERα and IL-6 in hepatocellular carcinoma were 39.0% (30/77), 45.4% (35/77) and 72.7% (56/77), respectively. The expression of ERα and p-ERα were negatively correlated with the expression of IL-6 (r=-0.468, P<0.01; r=-0.370, P<0.01, respectively). The positive rate of ERα in patients with tumor size≤5 cm, serum level of alpha-fetoprotein<400 µg/L, with complete encapsulation and non-microvascular invasion was significantly higher than those with tumor size>5 cm, serum level of alpha-fetoprotein≥400 µg/L, non-complete encapsulation and with microvascular invasion (all P<0.05). The overall survival rates of ERα-positive and ERα-negative patients were 66.7% and 23.4% (P<0.05). And the disease-free survival rates of ERα-positive and ERα-negative patients were 83.3% and 57.4% (P<0.05).

CONCLUSIONSThe tumor biological features of ERα-positive patients are better than that of ERα-negative patients. The role of ERα in hepatocellular carcinoma may be related to IL-6 level.
