Objective To establish an HPLC fingerprint ofJinjing solid beverage,and provide experimental evidence of evaluating its quality.Methods Ten batches ofJinjing solid beverage were analyzed by HPLC under the gradient elution condition. A Kromasil C18 column(4.6 mm×250 mm, 5μm) was used, and the flow phase was acetonitrile-H2O(acidified to 0.1% with phosphoric acid) with gradient elution, and the detection wavelength was 327 nm, and the flow rate was 1.0 ml/min, and the column temperature was 35℃. The data were evaluated by the similarity evaluation software for TCM fingerprint.Results The HPLC fingerprint ofJinjing solid beverage were established. Twelve common peaks including chlorogenic acid were identified with similarity of more than 0.9.Conclusion HPLC method is a reliable, available and quick method, that provides a means for controlling and evaluating the quality ofJinjing solid beverage.

BACKGROUND:Problems regarding the prosthesis in the horizontal plane and the rotation of the femur and tibia prosthesis on line are relatively weak. The distal femoral rotation axis is mainly the transepicondylar axis. Due to patient differences as wel as anatomy and intraoperative display, it is difficult to accurately locate the axis in the process of knee arthroplasty. OBJECTIVE:To investigate application of magnetic resonance technique in determining the axis of rotation of the distal femur, to provide reference and basis for femoral rotational alignment during total knee arthroplasty. METHODS:Data of 122 cases without knee joint disease, who were diagnosed and treated in the Department of Orthopedics of Nanyang City Center Hospital from September 2014 to October 2015, were analyzed. Magnetic resonance technique was used to measure femoral epicondyle axes (STEA), femoral epicondyle axes (CTEA), the anteroposterior axis (APL) and femoral shaft (PCL). Simultaneously, magnetic resonance technique was utilized to measure femoral ankle angle (PCA), ankle twist angle (CTA), axis vertical line and ankle axis angle (PAPA). Each data were tested three times, and the average value was calculatd. We analyzed the method of magnetic resonance technique to determine reference axis of distal femoral rotation. RESULTS ANDCONCLUSION: (1) Accuracy of the angle close to surgical transepicondylar axis: 3° PCL> CTEA > APL verticalline. (2) No significant difference in PCA was detected in two sets of measurements (P> 0.05). CTA and PAPA parameters in the first measurement by magnetic resonance imaging diagnosis were significantly lower than the second measurement (P< 0.05). (3) Results indicate that magnetic resonance technology provides ideal reference for distal femoral rotation, can accurately measure the CTA, PCA, PAPA andother indicators. It is a more reliable determination method and can be used in scientific determination of femoral rotational alignment reference axis in total knee arthroplasty. Except STEA, the accuracy of 3° PCL is highest.

Objective To study the inhibition activity of volatile oil from Mappianthus iodoies on SPC-A-1 and BEL-7402 cancer cells.Methods The volatile oil in Mappianthus iodoie was extracted by SFE-CO2.MTT assay was employed to test the antitumor effect of volatile oil from Mappianthus iodoies in two kinds of malignant tumor cell lines,with IC50 applied to evaluate the degree of inhibition activity.Results When the dose of volatile oil from Mappianthus iodoies was 200 μg/ml,the inhibition ratios of the tumor cell was in excess of 50％,the IC50 was 169.54,695.21 μg/ml respectively.Conclusion Volatile oil from Mappianthus iodoies extracted by SFE-CO2 has obvious inhibition activity on SPC-A-1 and BEL-7402 cancer cells.

Objective To investigate clinical features,diagnosis and surgery treatment of Hashimoto thyroiditis associated with thyroid carcinoma. Method Twenty-four cases of Hashimoto thyroiditis diagnosed by surgical pathology from January 2004 to December 2009 were associated with thyroid carcinoma. Results In the all 24 cases,22 cases (91.7% ,22/24) were associated with papillary thyroid carcinoma,including 12 cases (50.0% ,12/24) of micropapillary thyroid carcinoma,and 2 cases (8.3%, 2/24) were associated with medullay thyroid carcinoma. Thyroid colour ultrasound Doppler indicated that diffuse enlargement of thyroid with nodes occurred in 21 cases,account for 87.5%(21/24), single node occurred in 15 cases,account for 62.5%(15/24), 12 cases demonstrated thyroid nodes with calcification,account for 50.0%(12/24). Eight cases were examinated by fine-needle aspiration cytology biopsy(FNACB) before operation,examing results of 3 indicated thyroid carcinoma, account for 37.5%. Twenty cases were followed up 2 months to 6 years,no thyroid carcinoma recurred,4 cases missed. Conclusions Thyroid colour ultrasound Doppler examination plays an important role in diagnosis of Hashimoto thyroiditis associated with thyroid carcinoma before operation. It is necessary to investigate progressively the role of FNACB in diagnosis of Hashimoto thyroiditis associated with thyroid carcinoma before operation. Surgical exploration might become an important approach in diagnosis and treatment of Hashimoto thyroiditis associated with thyroid carcinoma.

ObjectiveTo explore the neural basis of visual completion for the occluded faces.Methods2 types of visual stimuli were presented randomly: pictures of complete faces,pictures of incomplete faces(the occluded part was the left-top quadrant).Subjects were instructed to perform a gender discrimination task while event-related potentials(ERPs) were recorded.ResultsCompared with complete faces,incomplete faces enhanced the amplitude of N1 on the occipito-temporal scalp bilaterally,with the right hemisphere advantage.The peak latency of N2 elicited by incomplete faces was delayed compared with that of complete faces.ConclusionThe enhancement of N1 is related to visual completion processing that requires additional time.

ObjectiveTo investigate if there were potential components similar to auditory mismatch negativity (MMN) in the visual modality.MethodsEvent-related potentials (ERP) of 15 healthy adults were tested. Subjects were demanded to complete shape-matching task and double-matching task under 4 kinds visual stimuli including no-difference (Nd), contour-difference (Cd), shape-difference (Sd) and double-difference (Dd).ResultsWithin P1-N1 latent period (100～140 ms), three kinds of deviant stimuli (Cd, Sd, Dd) elicited a positivity, mismatch positivity (MMP). MMP amplitude elicited by Dd was a sum elicited by Cd and Sd (single-difference).ConclusionIn the visual modality, MMP elicited by warp stimulus may be an element similar to auditory MMN and reflect auto-processing of brain to visual stimulus.

In this paper, two new concepts of DR (Dose Repulsion) and DG (Dose Gravitation) are presented with their calculation formulas. For the problem of selecting beam arcs in x-knife radiotherapy Planning system, a mathematics model of constrained optimization has been built. Furthermore, we have produced a feasible project of automatic selecting optimized beam arcs plan using SA (Simulated Annealing) arithmetic based on the distribution of the fields of DR and DG in the reduced phase space.
