Objective: To prepare salidroside (SAD) phospholipid complex in Rhodiola crenulota and search for its optimum preparation and characterization. Methods: Taking the ratio of salidroside and phospholipid as index, the factors that might affect the combination percentage of SAD with PLC (SAD-PLC) were investigated, separately. At the same time, UV, FT-IR, and XRD microscope anaIysis techniques were used to analyze the structure of SAD phospholipid complex. Results: In the optimum preparation process of SAD-PLC, tetrahydrofuran was used as reaction solvent, the weight ratio of SAD to phospholipid was 1:4, and the total concentration of SAD and PLC in the reaction solvent was 10 mg/mL, the reaction temperature was 20℃. Conclusion: The reaction ratio, concentration of SAD, and reaction time have geater impact on the formation of phospholipid complex, and the reaction temperature also has some impact. Chemical changes do not occur in the formation process, but the phospholipid complex is different with the simple physical mixtures.

AlM:To investigate the protective effect of astaxanthin (AST) on human retinal pigment epithelial (RPE) cells against oxidative damage induced by hydrogen peroxide (H2O2).METHODS:Human RPE cells were subcultured, cell activity was detected by MTT, rate of apoptosis was detected by flow cytometry and cell ultrastructure changes were observed under transmission electron microscope. RESULTS: MTT results showed that cell activity elevated to ( 53. 66%± 3. 25% and 70. 43%± 2. 38% after 10-8 mol/L and 10-4 mol/L AST treated. The difference had statistically significant (P<0. 05) compared with oxidative injury group (38. 76%± 3. 74%). Flow cytometry results showed that the apoptosis rate of RPE cells decreased to 30. 23%± 1. 91% and 12. 58%± 2. 12% in AST pretreated group, the difference was significant (P<0. 05) compared with oxidative injury group ( 42. 50%± 1. 94%); Electron microscopy showed that the morphology of cells gradually improved accompanied with the concentration of AST elevated.CONCLUSlON:AST may inhibit hydrogen peroxide-induced apoptosis of RPE cells, it can provide reliable evidence for pursue effective medicine to prevent and treat retina injury.

AIM:To point the susceptible gene in Avellino corneal dystrophy family with autosomal dominant inheritance.
●METHODS: Genomic DNA was extracted from the peripheral blood samples of all individuals of the pedigree. Several microsatellite makers were selected for gene scan in the hot regions of mutation. Linkage analysis was carried out using a Linkage software package. The haplotype data were processed using Cyrillic software to define the region of the disease gene.
●RESULTS: ln our pedigree, significant evidence of linkage was obtained at marker D5S396 and D5S393 [LOD score (Z)=3. 01, recombination fraction (θ)=0. 00]. The haplotype analysis of our pedigree was located between the microsatellite markers D5S808 and D5S638.
●CONCLUSION:The pathogenic gene of the Avellino corneal dystrophy pedigree is traced to a 11. 2 cM region in the chromosome 5q.

OBJECTIVETo explore the therapeutic effect and mechanism of Aitongping capsule (ATP) in treating cancerous pain.

METHODSSixty cancer patients were randomly divided into two groups, 30 patients in the treated group took ATP and 30 patients in the control group took diclofenac, 1 week of treatment was applied. The relevant clinical conditions of cancerous pain, the content of plasma beta-endorphin (beta-EP) and c-AMP, hemorheological index, improuement of life quality of patients, occurrence rate of adverse reaction were observed before and after treatment.

RESULTSThe total effective rate in the treated group and in the control group was 90.0 % and 83.3%, respectively, difference between them showed no significance. However, there were significant difference between the two groups in such aspects as the degree of pain relieving, the decrease of pain episodes, the shortening persistent time of pain and the initiation time of analgesic action and prolonged analgesic duration, the decrease of tenderness and percussion pain, the increase of plasma beta-EP content and the decrease of cAMP (P< 0.05 or P< 0.01). The evidences also showed that it was better in improving quality of life, ameliorating hemorheologic indexes and reducing incidence of adverse reaction in the treated group than in the control group (P <0.05 or P <0.01).

CONCLUSIONATP has affirmative effect on cancerous pain, its analgesic effect may be associated with the increasing of plasma beta-EP content, decreasing of cAMP level and ameliorating of hemorheologic indexes.

To investigate the pharmacokinetic characteristics and absolute bioavailability of ginkgolide A (GA), ginkgolide B (GB) and bilobalide (BB) in rats. In this experiment, a high-performance liquid chromatography-tandem mass spectrometry (LC-MS/ MS) method was established to determine the plasma concentrations of GA, GB and BB in rats after rats were administrated with the three drugs through ig and iv respectively. The main pharmacokinetic parameters and absolute bioavailability of three ginkgolide compounds were obtained by using pharmacokinetic software DAS 2. 0. After the inject of GA, GB and BB, the results showed Cmax at (513.9 ± 116.9), (701.3 ± 76.0), (5,255.6 ± 476.8) µg · L(-1) and AUC0.24h of (960.9 ± 268.5), (779.5 ± 140.6), (7,409.3 ± 1,181.1) µg · h · L(-1), respectively; after the oral administration, the results showed Cmax at (522.9 ± 39.9), (146.8 ± 31.6), (2,711.9 ± 588.9) µg · L(-1) and AUC0-24 h of (1,760.4 ± 300.7), (636.6 ± 180.3), (16,651.4 ± 1,306.5) µg · h · L(-1), respectively. The absolute bioavailability of GA, GB and BB in rats was (61.1 ± 10.4)%, (27.2 ± 7.7)%, (56.2 ± 4.4)%, respectively. The method established in this experiment has a good specificity and sensitivity and so can be used to study the pharmacokinetics and absolute bioavailability of GA, GB and BB in rats.

Objective To evaluate the value of echocardiography in diagnosing infective endocarditis (IE) in children. Methods The shape, size, echogenicity, distribution of vegetations and valvular function of the heart were observed by transthoracic echocardiography (TTE) in 30 patients with suspected IE. We correlated TTE ifndings with the results of hemoculture and serologic test. Results Vegetations were observed in all patients by echocardiography:seven patients with tricuspid valve vegetations, two with mitral valve vegetations, three with pulmonary valve vegetations, three with main pulmonary artery vegetations, three with aortic valve vegetations, two with aortic valve abscess, and two with vegetations in right atrium. After anti-infection therapy, the size of vegetations in iffteen patients became smaller and the less echogenic than before. Vegetations disappeared in two patients. Vegetation was recurrent repeatedly in one case. Ten patients recovered after operation. Two severe cases died. Five patients underwent TTE again one week after the previous negative TTE. Of them, echocardiography demonstrated vegetations in three cases. However, no vegetations were found in rest two cases because antibiotics had been used at early stage. In addition, echocardiography demonstrated one patient with mitral valve vegetation. But the lesion was ifnally conifrmed to be operating suture. The sensitivity and specificity of TTE in detecting vegetations were 88.0% and 80.0%, respectively. Blood cultures were positive in twenty-seven cases and were negative in three cases. Conclusions The early diagnosis of IE is important to improve patient′s prognosis. It takes a long time in organism cultivation before achieving the clinical diagnosis. TTE can help obtain an early diagnosis stage of IE, and provide the assessment of size and location of vegetation. It plays an important role in treatment and prognosis prediction.

This study deals with colony expansion characteristics, biomass increment and Na accumulation in mycelia of three ectomycorrhizal fungi ( Boletus edulis, Xerocomus chrysenteron and Gomphidius viscidus ) under treatment of Na2SO4 and NaCl. The experimental results showed that no impact was observed from Na2SO4 and NaCl treatments on the growth mode of the mycelia, but the biomass increment of X. chrysenteron and G. viscidus was significantly restrained under 0.1 mol/L Nacl. Under the treatment of Na2SO4, biomass increment of X. chrysenteron is significantly higher than the control, but the biomass of G. viscidus is lower than that of the control, and no significant impact was measured on growth of B. edulis under both treatments of Na2 SO4 and NaCl. The experiment also indicated that Na accumulation in mycelia varied significantly among the three tested strains, highest Na accumulation was measured in X. chrysenteron under treatment of NaCl, while under the treatment of Na2SO4 , accumulation of Na in B. edulis is much higher than the other two strains.
