Objective To probe the clinical values of the human serum glycoprotein profiles for the diagnosis of common gynecological tumors. Methods A total of 123 clinical serum samples which included 31 breast cancer, 24 cervical cancer, 19 ovarian cancer and 49 healthy individuals were collected. A lectin microarray consisting of 15 lectins with different glycan binding specificities was used to determine the glycoprotein profiles of serum sam-ples. Stepwise discrimination analysis method was adopted to establish function model of clinical serum samples classification with SPSS 15. 0 software. Results Two grades of diagnostic discrimination function models were es-tablished. The first grade discrimination function could differentiate gynecological tumors from healthy individuals, the diagnostic accuracy rates of retrospective inspection were 85. 7% and 83. 8% respectively, and the total diag-nostic accuracy rate was 84.6%. The second grade discrimination function was used to differentiate breast tumor, cervical tumor and ovarian tumor, the diagnostic accuracy rates of retrospective inspection were 96.8%,75.0%and 78.9% respectively, and the total diagnostic accuracy rate was 85.1%. Conclusion The human serum gly-coprotein profiles are associated with gynecological tumors, and the established discrimination function models based on lectin microarray data have a helpful reference value for the clinical diagnosis of gynecological tumors.

Chinese Journal of Information on Traditional Chinese Medicine 2006;0(06):-
Objective To determine the influence of total glucosides of paeony (TGP) on bone density, protein level of skeletal muscle and relative cytokine of osteoporotic rats. Methods Six-month-old SD rats were shamed as control (8 rats) or were ovariectomized (24 rats). The ovariectomized (16 rats) +TGP low dose and high dose group were treated with 50 mg/(kg?d) TGP and 150 mg/(kg?d) TGP respectively for 12 weeks. After the animals were sacrificed, IL-6, TNF-?, IGF-1, TGF-? in serum, protein level of skeletal muscle in right quadriceps femoris, and bone density of right femur and lumbar vertebra were determined. Results Compared with the ovariectomized group, the bone density and the protein level of skeletal muscle in TGP group increased significantly from the baseline (P

Objective: To establish the standard for quality control of Zhiganqing Granules (Radix et Rhizoma Rhei, Fructus Ligustri Lucidi, Rhizoma Alismatis, Pericarpium Citri Reticulatae, Polyporus Umbellatus, etc.) Methods: Fructus Ligustri Lucidi, Rhizoma Alismatis and Pericarpium Citri Reticulatae in the preparation were identified by TLC. The emodin in the preparation was determined by HPLC. A good linear range was shown at the concentration from 0.224?g to 0.732?g. The average recovery was 96.8% and the RSD was 1.14%.

Objective To observe effects for exercise and diet on learning and memory ability in mice with encephalon aging induced by D-galactose(D-gal).Methods The model of mice with encephalon aging was made by D-gal.The learning and memory ability of mice was determined by Morris water maze.Results There was significant difference between high fat feed encephalon aging group and restrict food on normal feed encephalon aging group,normal feed and exercise encephalon aging group,high fat feed and exercise encephalon aging group,high fat feed normal group,normal feed and exercise group,normal feed group(all P<0.05).In spatial probe test,there was significant difference between restrict food on normal feed encephalon aging group and normal feed encephalon aging group(all P<0.05).Conclusion Exercise and restrict food can improve the learning and memory function in the mice;feed with high fat can promote encephalon aging.

OBJECTIVE:To optimize water reflux extraction technology of Jiuwei yiwei mixture. METHODS:With the over-all score of the content of salvianoli acid B,a water-soluble component of the principal drug Salvia miltiorrhiza,the content of pae-oniflorin in Paeonia Radix Rubra and dry ointment yield rate as the observed index,and taking soaking time,extraction time, amount of water added,and extraction times as the factors,L9(34)orthogonal test was designed to optimize the extraction technolo-gy of Jiuwei yiwei mixture. And the verification test was conducted. RESULTS:The optimal technology was to add water with an amount 8 times as much as that of the drugs to soak them for 1 h and to conduct extraction twice,1 h for each. The overall scores of 3 batches of samples in the verification test were respectively 98.793,99.078 and 99.220(RSD<2%,n=3). CONCLUSIONS:The optimal technology for Jiuwei yiwei mixture is stable and feasible.

Objective To describe the reference intervals and their sources of tumor markers in clinical laboratories all over China.And make a comparison of difference between different testing systems.Methods The questionnaires about reference intervals of tumor markers testing were distributed to participants.The information was collected by external quality assessment software system based on website, which including upper and lower limits, sources, validation information and testing systems.The analytes were AFP, CEA, total-PSA, CA125, CA153, CA199, ferritin and free-PSA. The participants were classified according to the testing systems they used.The mean, median, maximum and minimum of each group were calculated using Microsoft Excel 2007.The difference of reference intervals between different testing systems were compared by Kruskal-Wallis test.Results The main source of reference intervals was instructions of testing system manufactures ( 83.1% for mean of 8 ratios ) .The next in sequence were instructions of reagent manufactures(8.4% for mean), National Guide to Clinical Laboratory Procedures (4.6%for mean), determined by their own laboratory(2.0% for mean) and the rest (1.9% for mean). There were 48.0% ( 1 906/3 967 ) of analytes whose reference intervals had been validated.Difference of reference intervals which was with P value of Kruskal-Wallis test with <0.05 was found between different testing system groups except the upper limit of free prostate specific antigen ( PSA ) .Conclusions Most clinical laboratories establish the reference intervals of tumor markers on the basis of instructions of testing system manufactures.The reference intervals among different testing systems have statistically significance.
