BACKGROUND: The method of replenishing kidney has becoming one of the therapies for anti-senility in gerontology in Chinese medicine.OBJECTIVE: To probe into the effects of the formula for nourishing kidney yin-zuoguiyin on serum malondialdehyde (MAD) content and superoxide dismutase (SOD) activity in metabolism of free radical.DESIGN: Complete randomized control experiment.SETTINGS: Microbiology and Immunology Department of Guangdong Medical College.PARTICIPANTS: The experiment was performed in Immunology Research Room of Wannan Medical College from September 2002 to July 2004. Forty male senile ICR mice were employed, provided by Institute of Experimental Animal of Medical Scientific Academy in Sichuan. They were randomized into senile control, zuoguiyin group, single shudi (Radix Rehmanniae Praeparata) group (single group) and shudi (Radix Rehmanniae Praeparata) removal group (removal group), 10 mice in each one. Zuoguiyin composes of shudi (Radix Rehmanniae Praeparata), shamyao (Rhizoma Dioscoreae), gouqi (Fructus Lycii), zhi gancao (Radix Glycyrrhizae Praeparata),fuling (Poria) and shangyurou (Fructus Corni) at the ratio of 9:6:6:3:4:5. After decocted routinely, the solution in zuoguiyin group was concentrated to 0.577 5 g/mL of raw herbs contained; that in single group was to 0.157 5 g/mL and that in removal group was to 0.42 g/mL. The mixed medical solutions of 100 g/L were prepared successively in each group.INTERVENTIONS: In zuoguiyin group, single group and removal group,solutions of zuoguiyin and shudi (Radix Rehmanniae Praeparata) and solution with shudi (Radix Rehmanniae Praeparata) removed were administrated successively, 4 times/day, 1.5 mL/time, totally for 75 days. No any drink was provided during the medication. The mice in senile control drank pipe water. After the eyeball extracted, blood of 2 mL collected and serum preserved, the thiobarbituric acid method was used to determine MAD content, the xanthine oxidase method was to determine SOD activity and the colorimetric method was to determine general capacity of anti-oxidation in serum.MAIN OUTCOME MEASURES: ① serum MAD content; ② serum SOD activity; ③ general capacity of anti-oxidation in serum.RESULTS: One mouse was dead in senile control and 3 mice in single group. Terminally, 36 mice entered result analysis. ① MAD content:Serum MAD content in zuoguiyin group and single group were lower than that in senile control [(5.280±1.204) μmol/L and (5.886 2.717) μmol/L,(9.533 3.494) μmol/L, (q=3.641-4.657, P ＜ 0.05)]. Serum MAD content in zuoguiyin group and single group were basically same. ② SOD activity: SOD activity in zuoguiyin group and removal group were higher than senile group [(7.008±0.782) mkat/L and (6.989±0.809) mkat/L, (5.908±0.392) mkat/L,(q=3.641-4.657, P ＜0.05)]. SOD activity in zuoguiyin group and removal group were basically same and that in single group and senile control were basically same. ③ General anti-oxidation capacity: The general capacity of anti-oxidation in serum in zuoguiyin group and single group were stronger than that in senile control, that in removal group was weaker than senile control, but the differences were not significant (P ＞ 0.05).CONCLUSION: Zuoguiyin remarkably reduces MAD content and improves SOD activity in serum of senile mice. It is indicated that zuoguiyin acts remarkably on improving metabolism of free radical in senile body,strengthening SOD activity and reducing organic injuries caused by MAD accumulation.

Objective:To explore the effect of zuoguiyin and its partial prescriptions on cellular immune function in senile mice.Methods:Healthy male ICR senile mice were divided into 4 groups at random: old contrast group, ZGY group, prepared rhizome of rehmannia(PROR) group and none prepared rhizome of rehmannia(NPROR) group. The senile mice had been drunk zuoguiyin and its partial prescriptions for 75 days, then observing the differences through thymic index, spleen index, activity of T lymphocyte and the level of IL-2 after using different drugs.Results:Acted by ZGY, ZGY had enhanced cellular immune function of senile mice, appearing that thymic index, spleen index, activity of T lymphocyte and the level of IL-2 were distinctly higher than those of the old contrast group. Compared to ZGY,prepared rhizome of rehmannia also enhanced the activity of T lymphocyte. However, it had no effect on thymic index, spleen index and the level of IL-2.So its effect on anti-senility was not better than ZGY. None prepared rhizome of rehmannia group had no distinct effect on those indexes.Conclusion:Zuoguiyin had an action of antisenility by improving cellular immune function.

[Objective]To discuss the alterations of sesamoid position before and after opertation and its relation to the function of the metatarsophalangeal joints.[Methods]Eighty feet(39 hallux valgus feet,41 normal foot) were selected.The distance from sesamoids to the second metatarsal,the relative position of sesamoid bone to the first metatarsal bone,the function of the first metatarsophalangeal joints were determined and analyzed.[Results]The distance from sesamoid to the second metatarsal had no statistical significance in normal feet compared with the hallux valgus feet(P

Objective To discuss the feasibility and safety of early enteral nutrition (EN) on treatment of severe acute pancreatitis (SAP) and its influence. Methods The advancement about application of early EN on treatment of SAP in recent years were reviewed. Results In patients with SAP, early EN via catheter placed in the jejunum could protect the integrity of intestinal barrier and reduce infectious complications. But no consensus had been reached about the starting time, ingredient and infusion mode yet. Conclusion Early EN may have positive effects on treatment of SAP, but further researches are still needed.

Objective To detect normal rat jejunum epithelial cells to learn about the distribution of peptide YY(PYY)receptor and measured two important parameters of PYY receptor so as to explore the target that PYY binds to and display its physiological function.Methods Receptor radioligand assay was conducted by using 125I-PYY to detect normal rat jejunum epithelial cells.We also measured receptor dissociation constant(Kd),the affinity or the ability that the receptor could bind ligand;maximum binding capacity(Bmax),the concentration of binding site;and Hill coefficient.Results There were PYY receptors in normal rat jejunum epithelial cells.Dissociation constant(Kd)of PYY receptor was(386.69?129.95)pmol/L.Maximum binding capacity(Bmax)was(303.21?116.85)fmol/mg protein.Hill coefficient was 1.PYY receptor had high affinity.Conclusion There are distributions of PYY receptors in normal rat jejunum epithelial cells.Kd means that PYY receptor has high affinity.Bmax means that the number of receptors is limited and decides the characters of saturability.We think that PYY directly inhibits secretion by binding to PYY receptor in jejunum epithelial cells when PYY inhibiting jejunum secretion.

Objective To evaluate the dynamic MR imaging findings of peripheral cholangiocarcinoma (PCC) of the liver. Methods Seventeen patients with PCC underwent dynamic MRI during the early, middle, and delayed phase after contrast medium administration. Enhancement pattern of the tumor, the wedge-like enhancement area peripheral to the tumor, dilatation of the intrahepatic biliary ducts, vascular involvement, and extrahepatic tumor invasion were evaluated. Results Early peripheral enhancement with progressive and concentric filling by contrast medium was the most frequent enhancement pattern (9 patients). A wedge-like enhancement area was observed in 10 patients. Ductal dilatation was found in 11 patients. Vascular involvement and extrahepatic invasion were seen in 8 and 2 patients, respectively. Conclusion Enhancement pattern is relative to the character of pathology (quantity and distribution of cell and fibrosis). Early peripheral enhancement with progressive and concentric filling by contrast medium may be specific for PCC.

Sclerosing cholangitis includes a spectrum of chronic, variably progressive cholestatic liver disease characterized by inflammation, fibrosis and stricture of the intrahepatic and extrahepatic bile ducts. Sclerosing cholangitis can be divided into primary sclerosing cholangitis of unidentified etiology and secondary sclerosing cholangitis caused by various identifiable etiologies, including immunoglobulin G4-related sclerosing cholangitis, recurrent pyogenic cholangitis, ischemic cholangitis, acquired immunodeficiency syndromerelated cholangitis and eosinophilic cholangitis. In this article, we describe the imaging findings of the various spectrums of sclerosing cholangitis with anemphasis on a systemic approach in differential diagnosis. It is very important for magnetic resonance cholangiography and endoscopic cholangiography in imaging diagnosis and differential diagnosis of sclerosing cholangitis. We also discuss the clinical significance and therapeutic options for treating sclerosing cholangitis.
