AIM:To discuss Daidzein intravitreal injection whether has protective and recovery effects on acute nerve damages.
METHODS:After the crush models of acute optic nerve were set up, 72 males SD rats were divided into 4 groups randomly as common group without surgery, FBS negative control group, Daidzein treatment group ( 10μmol/L, 100μmol/L, 1000μmol/L ) and positive control group using rats nerve growth factor ( mNGF, 100ng/mL ). Three days after interference, all experimental animals were executed. HE staining was used to evaluate morphologic change of the retina, immunohisochemical staining and western-blot tests for identifying and quantifying the distinct expression of Caspase-3 and GAP-43 among the groups.
RESULTS: Compared with the normal group and negative control group, retinal morphology of different concentrations of each Daidzein treatment group and positive control group was more complete, the expression of Caspase-3 protein was relatively lower, the expression of GAP-43 protein was relatively higher, the differences have statistically significance (P<0. 05).CONCLUSION: Daizein injection in the vitreous cavity has the capacity of protection and restoration in rat's acute nerve damages.

Objective To study compatibility rule of herb-pair in rhubarb after compatibilities with fructus aurantii Immaturus,Chinese goldthread rhizome,moutan cortex,peach seed and kansui radix stir-baked with vinegar, and to observe its anti-inflammation and acute toxicity. Methods Mice were gavaged by 15,30 g?kg-1 rhubarb and rhubarb, rhubarb frutus aurantii immaturus rhizoma coptidis, radix et rhizoma rhei peony, rhubarb, semen persicae and rhubarb extracts from euphorbia kansui, respectively, in the morning and evening once, for 7 d.The effects of five different compatibility of Rhubarb on acute inflammation were observed in the mouse paw swelling induced by carrageenan. The classical method were used to determine acute toxicity of rhubarb and the contents of five different compatibility of rhubarb. Results Compared with the control group, the contents of five different compatibility of rhubarb with high and low dosage groups(30,15 g?kg-1 ) could inhibit the paw edema in mice,reduce NO and MDA production and enhanced activity of SOD in mice inflammatory tissue. The LD50 was not determined. Calculated by crude drug content, the MLD of rhubarb compatibilities with fructus aurantii immaturus, Chinese goldthread rhizome,moutan cortex,peach seed and kansui radix stir-baked with vinegar were 145.33,142.30,117.53,103.45, 113.09,182.36 g?kg-1 respectively, which were respectively equal to 581,569,470,418,452 ,729 times of people, s daily dried medicinal herb dosage. Conclusion The five different herb-pair have anti-inflammation effects after compatibility of Rhubarb, and it got best effects when rhubarb compatibility with kansui radix stir-baked, the next were rhubarb compatibility with Chinese goldthread rhizome and moutan cortex. It was basic security and low toxicity of herb-pair in rhubarb after compatibilities.

Objective:To study the mechanism of moxibustion therapy on diabetic peripheral neuropathy for the peripheral neuroprotection.Methods:The DPN model was induced by intraperitoneal injection with streptozotocin (STZ).The rats were given moxibustion at the acupoint Yishu (Extra) and the acupoint Zusanli (ST 36).The treatment was carried out once a day and 15 minutes per acupoint,lasting for 56 d in total.The clinical effect of moxibustion was evaluated by detecting blood sugar,urine sugar,body weight and dietary intakes,as well as nerve conduction velocity with neuroelectrophysiological method.The structure variation of sciatic nerve was observed by HE staining and light microscopy,and the level of NGF in the sciatic nerve Was determined by ELISA.Results:Compared with the model group,the plasma glucose was significantly lower in the moxibustion group (P＜0.01),with significantly faster nerve conduction velocity (P＜0.01),more notably changes in pathological appearance (P＜0.01) and higher level of nerve growth factor (NGF)(P＜0.01).Conclusion:Moxibustion could improve the symptom and signs of peripheral neuropathy in rat models with DPN,which may relate to the increased NGF and enhanced peripheral nerve protection.

AIMA bioassay method was established for the determination of active concentrations of lidamycin and studied its pharmacokinetics in mice and dogs.

METHODSCytotoxicity of lidamycin in vitro was used to determine drug serum concentrations in vivo.

RESULTSValidity of methodology met the requirements of pharmacokinetic study. The concentration-time profile in mice after iv lidamycin of 100, 50 and 10 microg x kg(-1) was best fitted with 2-compartmental model with T1/2alpha and T1/2beta of 0.77-1.8 min and 5.6-7.2 min, respectively. The AUC were 2851.3, 887.8 and 166.4 microg x min x L(-1), respectively and increased with dose nonlinearly. There were similar trends between AUC and the potency of tumor growth inhibition. After iv lidamycin of 12 microg x kg(-1) in dogs, the concentrations of lidamycin decreased rapidly and the AUC was 16 microg x min x L(-1), which were lower and quicker than those in mice. The levels in serum after second administration at day 15, were lower than those of the first.

CONCLUSIONActive concentrations and pharmacokinetics of lidamycin were obtained by bioassay method successfully. There are species differences and single and multi-dosing differences in the pharmacokinetics of lidamycin.

The epidemiological survey of prevalence of NIDDM (non-insulin dependent diabetes mellitus) and IGT(impaired glucose tolerance)was conducted among 9450 residents aged 25～70 in some areas of Hubei Province, China. The results show that NIDDM and IGT prevalences are 2.62% and 4.48%, respectively. There is no significant difference between male and female (P>0.05). The NIDDM prevalence in cities is slightly higher than that in countryside, but the difference is not significant (P>0.05). However, the IGT prevalence in city is significantly higher than that in countryside (P<0.01). The prevalence of both NIDDM and IGT is increasing along with the age of the population. It is also significantly related to the family history of NIDDM, hypertension, and high body mass index (BMI). By using stepwise logistic regression to analyse the risk factors of NIDDM, age (OR=1.86),BMI(OR=2.69), family history (OR=2.84) and hypertension (OR=2.23) entered the model (significance level is α=0.05).

Blood-eye barrier (BEB) is one of the most important structures of organism to maintain homeostasis of the eye. However, it is the major constraint for the medication of intraocular diseases. Traditional Chinese medicines have distinctive advantages for the treatment of intraocular diseases, which can be used to regulate the physiological function of human body with low toxicity. In this article, we have briefly summarized the feature of BEB, with the domestic and foreign literatures combined, and mainly reviewed current progress in the field of study on the permeability of traditional Chinese medicines and effective components in BEB and promoting methods.
