The experiment was designed to study the mechanism of increasing efficiency of Ligustrum lucidum steamed with wine. Rats in vivo with gastrointestinal perfusion model were used. The contents of salidroside and specnuezhenide in the fluid of gastrointestinal perfusion of rats were measured by HPLC at different time points after dosing. Then the K(a) and absorption percentage were calculated. Specnuezhenide could be detected in the fluid of gastrointestinal perfusion of specnuezhenide. The K(a) of the specnuezhenide and salidroside in the fetal intestines are 0.055 3 and 0.144 2 h(-1) respectively and the total absorptivity are 24.46% and 60.14% respectively after 4 hours. The K(a) in the stomach are 5.70 and 8.26 h(-1) respectively and the total absorptivity are 34.21% and 47.23% respectively after 4 hours. The experiment proved that specnuezhenide can be metabolized into salidroside which is more beneficial for gastrointestinal absorption. The experiment proved that specnuezhenide can be metabolized into salidroside both in the rat's stomach and the fetal intestine and compared with the specnuezhenide salidroside is more conducive to gastrointestinal absorption. The results suggested that the increasing efficiency on liver and kidney of L. lucidum steamed with wine has business with the fact that Specnuezhe nide is more conducive to the body after it is changed into salidroside.

OBJECTIVE:To establish a method for the determination of dissolution of Xiaocaihu pill,and compare the differ-ence of preparation from different manufacturers. METHODS:Using 0.1 mol/L HCl as dissolution medium,rotating basket method was used to determine the dissolution of preparations. HPLC was adopted to determine the content of baicalin:column was TSKgel ODS C18 with mobile phase of methanol-water-phosphoric acid (65∶35∶0.7,V/V/V) at a flow rate of 1 ml/min,detection wave-length was 280 nm,column temperature was 30 ℃,and injection volume was 5 μl. RESULTS:The linear range of baicalin was 0.488-124.8 mg/L (r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 2.0%;recovery was 100.14%-104.78%(RSD=1.58%,n=9). The average t50(50% dissolution time)of baicalin was 85.81 min. CONCLUSIONS:The method is simple with good precision,stability and reproducibility,and can be used for the dissolution determination of Xiaocaihu pill. Xiaocaihu pill from different manufacturers shows great differences,both preparation formulation and clinical use should attach importance to the dissolution of solid preparations.

Objective To compare adductor canal block(ACB)with topical anesthesia for postoperative analgesia in the patients undergoing arthroscopic knee surgery.Methods Sixty patients of both sexes,aged 18-64 yr,with body mass index of 18-30 kg/m2,of American Society of Anesthesiologists physical status ⅠorⅡ,scheduled for elective arthroscopic meniscectomy,were divided into 2 groups (n=30 each) using a random number table:ACB group and topical anesthesia group(TA group).In group ACB,0.2% ropivacaine 20 ml was injected into the adductor canal under the guidance of ultrasound at 30 min before operation to perform ACB.In group TA,0.25% ropivacaine 20 ml was injected into the articular cavity at 5 min before the end of operation.The development of effective analgesia (VAS scores ≤4)and weakened quadriceps femoris muscle strength(muscle strength 0-2 grade,post-operative muscle strength was assessed by using manual muscle testing),related complications(local anesthetic intoxication,bleeding at the puncture site and hematoma) and occurrence of postoperative nausea,vomiting and delayed emergence were recorded.Results Compared with group TA,the rate of effective analgesia within 12 h after surgery was significantly increased (P<0.01),and no significant change was found in the incidence of weakened quadriceps femoris muscle strength,nausea and vomiting in group ACB(P>0.05).Local anesthetic intoxication,bleeding at the puncture site,hematoma or delayed emergence was not observed in the two groups.Conclusion ACB produces better efficacy for postoperative analgesia than topical anesthesia in the patients undergoing arthroscopic knee surgery.

OBJECTIVE Toexploretheantidepressanteffectsofalbiflorinandtheinvolvementof hypothalamic-pituitary-adrenocortical (HPA) axis function in its antidepressant potency.METHODS Two weeks after the olfactory bulbectomized (OB)surgery,albiflorin (2.5 ,5.0 ,10.0 mg·kg -1 ,ig) and imipramine 5.0 mg·kg -1 (ig)were given to rats twice a day for 14 d.The open-field test was con-ducted to evaluate the move ment distance,move ment ti me and velocity of olfactory bulbecto mized rats and sham-operated rats.The serum levels of corticosterone(CORT)and adrenocorticotropic hormone (ACTH)in rats were measured by the enzyme linked immunosorbent assay.The expression levels of glucocorticoids receptor (GR)in the hippocampus of the rats were analyzed using Western blot proce-dures.RESULTS Comparedwithsham-operatedrats,movementdistance,movementtimeandveloci-ty of the OB rats were significantly increased (P<0.01 ).Albiflorin 1 0.0 mg·kg -1 significantly reduced the movement distance,movement time and velocity of OB rats (P<0.05)after being given for 7 d. The movement properties were significantly reduced by albiflorin 5.0 and 10.0 mg·kg -1 when given for 14 d (P<0.05).The OB rats demonstrated significantly increased levels of serum CORT and ACTH (P<0.01 )and decreased GR expression in the hippocampus (P<0.01 ).Albiflorin 2.5,5.0 and 10.0 mg·kg -1 significantly reduced the serum CORT and ACTH levels (P<0.05),while albiflorin 5.0 and10.0mg·kg-1increasedtheexpressionofhippocampalGR(P<0.05).CONCLUSION Albiflorin may have re markable behavioral antidepressant effects on olfactory rats and one of the related mecha-nis ms may be its regulation of the hyperactivity of HPA axis function.

· AIM: DLAD (DnaseII-like acid Dnase) is an acid DNase that is highly expressed in human and murine lens fibre cells. Recently, the DLAD-/- mice with a deficience in DLAD gene were reported to develop nuclear cataract.To elucidate whether a deficient DLAD gene can cause some human cataract, we studied autosomal dominant nuclear catarat in 6 families and analysed linkage between cataract and DLAD locus.·METHODS: Two-point Lod score values were obtained for markers D1S551 and GATA65B07.· RESULTS: The results show negative Lod scores (z=-∞ at θ =0), so linkage was excluded between the defect and DLAD locus in these families.·CONCLUSION: no evidence for cataracts in these families linkage to chromosome 1p22.3, the DLAD locus.
