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.

After the concept of symptoms in traditional Chinese medicine was defined, the classification of symp-toms in traditional Chinese medicine and the characteristics of clinical diagnosis and treatment in traditional Chinese medicine were described .It was suggested that the symptoms in traditional Chinese medicine should be classified into 3 kinds, namely symptoms and signs according to the 4 diagnostic methods, symptoms and signs according to the diagnostic devices, symptoms and signs according to the physical constitutions of patients in order to lay a foun-dation for improving the classification in clinical term system of traditional Chinese medicine.

Objective To evaluate the clinical effect of artificial liver support system (ALSS)on serum high -sensitivity C -reactive pro-tein (hs -CRP)level and investigate the influence of the change in hs -CRP level on clinical prognosis among patients with hepatic failure. Methods Patients were recruited into three groups:group one included 60 patients who received ALSS due to hepatic failure;group two in-cluded 37 patients with hepatic failure without ALSS treatment;and group three included 37 patients with chronic hepatitis B.The serum levels of hs -CRP were measured in groups two and three,and in group one before and after ALSS treatment.Comparison of continuous data between groups was made by t test,and comparison of categorical data was made by chi -square test.Results The levels of hs -CRP in group one before treatment and in groups two and three were 12.89 ±9.39,12.22 ±9.73,and 2.83 ±6.79,respectively.No significant difference in hs -CRP level between group one and group two was observed (P >0.05).However,the hs -CRP level in group three was significantly different from those in group one and group two (P <0.001 ).The improvement rate in group one after ALSS treatment (78.3%)was significantly higher compared with that in group two (54.05%)(χ2 =6.315,P <0.05).ALSS treatment (t =5.179,P <0.05).ALSS treatment was selectively effective in a subgroup of patients and greatly decreased the hs -CRP level in these patients (t =5.344,P =0.000),resulting in a significant difference from the patients who were unresponsive to ALSS treatment (t =2.368,P =0.038).Conclusion Artificial liver support system can decrease the hs -CRP level in patients with hepatic failure.Serum level of hs -CRP can be used as a clinical indicator of disease progression and predict the clinical outcomes of ALSS in patients with hepatic failure.

In recent years, microRNAs (miRNAs) have been found to be one of the key factors of post transcriptional gene regulation, which are involved in occurrence and development of many diseases. Peritoneal dialysis (PD) has become an effective alternative treatment approaches for patients with end stage renal disease (ESRD). Peritoneal fibrosis is one of the most important factors leading patients to withdraw from long-term PD, hence restricts the application and development of PD. MicroRNAs are closely related to the development of peritoneal fibrosis. This article reviews the role of miRNAs in the pathogenesis and treatment of peritoneal fibrosis.

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 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.
