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.

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.

Abstract: Objective　To explore the value of real-time shear wave elastography in evaluating the severity of liver fibrosis in hepatitis B, and to analyze the factors that affecting its accuracy. Methods　A total of 196 chronic hepatitis B patients, who admitted to the Third Affiliated Hospital of Chengdu Medical College from February 2018 to October 2020, were selected for retrospective analysis. Demographic indicators such as gender, age, body mass index(BMI), and laboratory indicators such as fasting blood glucose, liver function, and blood lipid composition were collected. The patients were detected by real-time shear wave elastography. Taking the pathological test results as the gold standard, the diagnostic value of real-time shear wave elastography in the severity of liver fibrosis in chronic hepatitis B was analyzed, and the comprehensive effect of various factors on the diagnostic accuracy of real-time shear wave elastography was evaluated by Logistic regression analysis. Results　The differences in real-time shear wave elastography of patients with different severity of liver fibrosis in hepatitis B were statistically significant, and F0 grade

Objective:To establish an HPLC method for the determination of entrapment efficiency of matrine microspheres .Meth-ods:A Fortis XiC18 (250 mm ×4.6 mm, 5μm) column was used , the mobile phase consisted of methanol-acetonitrile-3%phosphoric acid solution (11∶80∶9).The flow rate was 0.6 ml· min-1.The detection wavelength was 210 nm, the column temperature was at 25℃and the sample size was 20 μl.Results: The linear range of matrine was 3-150 μg · ml-1 ( r =0.999 7).The recovery was 99.92%(RSD=0.97%, n=9).The entrapment efficiency of matrine microspheres was 81.85%±3.22%(n=3).Conclusion: The method is suitable for the determination of entrapment efficiency of matrine microspheres .

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 observe the abnormality of gray matter volume and density in patients undergoing postoperative delirium (POD).Methods Forty-seven cases of aged patients, 26 males and 21 females, aged 60-75 years, ASA physical status Ⅱ or Ⅲ, were selected.On the third day after operation, cognitive function estimation was performed.The patients were assigned into group POD and group C according to whether POD occurred and brain magnetic resonance imaging (MRI) scanning was implemented.The discrepancy in gray matter volume and density between the two groups were compared using voxel-based morphometry method (VBM).Correlation analysis was performed between the corresponding parameters in the regions where notable differences between the two groups existed and minimum mental state examination (MMSE) score were found.Results Global gray matter volume of group POD was notably lower than that of group C (P<0.01).Cerebrospinal fluid volume of group POD was significantly higher than that of group C (P<0.01).Gray matter volume of bilateral frontal gyrus and right parahippocampus was remarkably reduced in group POD (P<0.001).Gray matter density of bilateral hippocampus and right parahippocampus decreased significantly (P<0.001).Right parahippocampal gray matter volume was positively correlated with MMSE score in POD patients (P<0.05).Conclusion Structural abnormality in frontal regions, hippocampus and parahippocampus may play an important role in pathogenetic and developing process of POD.Gray matter volume in the right parahippocampus may be one of reference index for POD severity.
