Objective To evaluate the imaging features of patients with vascular cognitive impairment (VCI) induced by Subcortical Ischemic Vascular Disease (SIVD), through magnetic resonance diffusion tensor imaging ( DTI ) and proton spectroscopy ( MRS ) technology. Methods A total of 52 patients with SIVD were enrolled. After analysis of scale score, 32 patients with cognitive impairment were assigned to VCI group and 20 patients with no cognitive impairment were assigned to control group. Both group received DTI and MRS examination. The mean values of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) of the bilateral temporal, frontal, parietal and occipital white matter regions as well as in the bilateral centrum semiovale were calculated. The peak value of MRS of N-acetyl aspartate (NAA) , choline ( Cho), creatine (Cr) and phaseomannite ( mI ) were calculated. Results Compared with control group, FA decreased in the region of temporal, frontal, parietal as well as in the centrum semiovale , and ADC increased in VC[group ( P < 0.05 ) . In the frontal regions and centrum semiovale,the VCI patients had a significant FA decrease. The ADC value increased obviously in the temperal lobe.Spectrum analysis results showed, NAA/Cr was lower than control group in VCI group in the frontal lobe (1.43 ±0.08 vs 1.53 ± 0. 92), while mI/Cr was higher than control group in the temporal lobe(0. 51 ±0. 06 vs 0. 46 ± 0. 07 ) ( P < 0. 05 ). Conclusion FA in the temporal and centrum semiovale regions of VCI group and NAA in the temporal white matter regions decreased obviously. DTI and MRS could provide a reference value for early diagnosis and assessment of VCI.

Objective To study the imaging features of Scheuermann disease and compare the value of MRI, X-Ray and CT images in diagnosis of this disease. Methods The images of 14 Scheuermann disease patients were analyzed retrospectively. Results The pathological changed vertebraes have wedge-shaped changes in different degree. The edges of the vertebraes manifest roughness and have become step-shaped, or Schmorl′s nodes were demonstrated. Conclusion The multi-vertebraes wedge-shaped changes and the Schmorl′s nodes are the main imaging features of Scheuermann disease. The pathological change occurs in the different spine segments, and the imaging features are not completely same. X-Ray and MRI images are more important in diagnosis of this disease. MRI Multi-direction imaging displays clearly the Schmorl′s nodes, marrow dropsy, the fat accumulation and the intervertebral disc denaturation. What′s more important is that MRI has its own superiority in the differential diagnosis of this disease.
7. Analysis and Comparison of HPLC Fingerprints of Natural and Artificial Agarwood
Chinese Pharmaceutical Journal 2019;54(23):1980-1987
OBJECTIVE: To establish the HPLC fingerprint analysis method for agarwood with compare the natural agarwood and artificial agarwood combined with the contents of ethanol-soluble extraction (E%) and agarotetrol (A%). METHODS: The E% and A% were determined according to the ChP(2015). The chromatographic fingerprints of agarwood were established on a Platisil ODS C18 column (4.6 mm×250 mm, 5 μm) with mobile phase consisting of acetonitrile-0.1% formic acid. Gradient elution was performed at a flow rate of 0.7 mL•min-1, the detection wave length was set at 252 nm, and the column temperature was maintained at 31 ℃. The similarity evaluation system of traditional Chinese medicine chromatographic fingerprint (2004A) was used to establish the common pattern and calculate the similarity of chromatograms. Principal component analysis (PCA) was used with multivariate statistical analysis software for relative peak area of common chromatographic peak. RESULTS: The chromatographic fingerprint similarity of 13 batches of natural agarwood was 0.021-0.856, the E% was 10.1%-31.0%, and the A% was 0.04%-2.83%, respectively. The chromatographic fingerprint similarity of 11 batches of artificial agarwood ranged from 0.079 to 0.453, and the E% and A% were 10.3%-31.3% and 0.14%-1.02%, respectively. Thirteen batches of natural agarwood and 11 batches of artificial agarwwod were divided into two groups respectively, and the reference crude drug was gathered in the natural agarwood group. The similarity between natural and artificial agarwood chromatographic fingerprint was significantly different (P<0.05). Meanwhile, the similarity of artificial agarwood chromatographic fingerprint was positively correlated with the E% (P<0.05). CONCLUSION: The chromatographic fingerprint analysis combined with multivariate statistical analysis can easily and quickly distinguish natural and artificial agarwood, which provides a reference for the comprehensive evaluation of the quality of agarwood.

OBJECTIVE:
To discuss the clinical features and treatment methods for simple orbital blowout fracture.
METHOD:
Retrospective analysis of the CT images of 16 orbital blowout fracture case, and identification of the sites, degree, patterns and features of fractures. Among the 16 cases, 2 cases adopted conservative treatment; 11 cases gained a reduction of orbital fracture through endoscopic transnasal surgery; the other 3 patients choosed endoscopic transnasal surgery and Caldwell-Luc operations.
RESULT:
Among 16 diplopia cases, 13 cases were completely cured, and 3 patients' vision were significantly improved. Among 11 enophthalmos cases, 10 patients were cured, and the effect of the other one was not satisfied. Among the 15 eye movement disorder cases, 13 patients' eye movement gained a full recovery, and the other 2 cases were nearly normal. All patients' vision were improved in different extents, and no one got a complication.
CONCLUSION
Computerized Tomography is helpful to the diagnosis of simple orbital blowout fracture. Caldwell-Luc operation with transnasal endoscope is an effective method for the treatment of orbital fractures.

AIM To establish a high performance liquid chromatographic method (HPLC) to determine the concentration of valsartan in human plasma. METHODS Separation was achieved on the lichrospher C 18 column. The mobile phaseconsisted of pH 3 1 phosphate buffer acetonitrile (53∶47, V/V) was used at a flow rate of 1 0 ml?min -1 . The fluorimetric excitation and emission wavelengths were set at 265 nm and 378 nm, respectively. The plasma samples were acidified with HCl, extracted with ethyl acetate. Separate the organic phase, remove the solvent and then residue was dissolved in mobile phase. RESULTS The retention time of valsartan was 12 5 min. The calibration curves were linear in the range of 5 9~ 2 360 ?g?L -1 . The precision values (RSD) of intra day and inter day were determined to be 2 83%~7 07% and 1 57%~8 41% respectively. The absolute recovery rate were 80 30%?5 13%. The method was applied to determine the peak and valley concentrations in plasma of the hypertensive treated with 80mg valsartan per day. CONCLUSION The assay was sensitive and simple. It is suitable for the study of the pharmacokinetics of valsartan.

OBJECTIVETo study the predicting effect of proly 4-hydroxylase beta polypeptide (P4HB) in treating non-small cell lung cancer (NSCLC) patients by Yiqi Chutan Recipe (YCR).
METHODSTotally 46 stage III and IV NSCLC patients were treated by YCR for 4 therapeutic courses. Effect was assessed by RECIST of solid tumor. P4HB expression was detected in the lung cancer tissue by immunohistochemical assay. Factors affecting disease control rates (DCR) of YCR were analyzed by Logistic regression analysis. The correlation between P4HB expression and the effect of YCR was analyzed.
RESULTSThe DCR of advanced NSCLC treated by YCR was 36.96% (17/46 cases). P4HB was high expressed in advanced lung cancer tissue (6/15 cases). Gender, initial treatment, and retreatment are independent factors for affecting DCR of treating lung cancer by YCR.
CONCLUSIONP4HB might be taken as a factor for predicting the effect of YCR in treating NSCLC.
