OBJECTIVE:To investigate the regularity of Chinese patent medicine prescriptions for Qi deficiency and blood sta-sis syndrome (QDBSS),and to provide reference for studying QDBSS diagnosis standard and new TCM for related symptoms. METHODS:Chinese patent medicine for QDBSS were collected from Chinese Pharmacopoeia (2015 edition) and Chinese Mate-ria Medica Preparation(1993 version). The regularity of Chinese patent medicine prescriptions and symptom association rule were analyzed by using TCM inheritance auxiliary system (V2.5). RESULTS:Among the 171 symptoms,chest tightness,shortness of breath,chest pain,fatigue and palpitation were common symptoms,and three groups of symptoms were included as chest tight-ness-shortness of breath-chest pain-palpitation-irregularly pulse;mouth and eye deviation-numbness of hands and feet-hemiple-gia-stiff tongue-spasm;hypomenorrhea-irregular menstruation-abdominal mass-dysmenorrheal. One hundred and thirty-one Chinese patent medicines included 304 ingredients,top 5 in the list of frequency were Astragalus membranaceus,Salvia militiorrhiza,An-gelica sinensis,Ligusticum chuanxiong,Panax ginseng. A. membranaceus- A. sinensis,L. chuanxiong-A. sinensis,S. militiorrhi-za-A. membranaceus,L. chuanxiong- A. membranaceus and L. chuanxiong-S. militiorrhiza were frequently used herbal combina-tions. A. membranaceus-A. sinensis-L. chuanxiong-S. militiorrhiza-P. ginseng-Carthamus tinctorius-Panax notoginseng was the core combination. A new prescription for QDBSS was formed (P. ginseng-Radix Paeoniae Rubra-borneol-Gastrodia elata-artificial moschus-Myristica fragrans). CONCLUSIONS:QDBSS has common symptoms which exist in many kinds of diseases,such as chest tightness,chest pain and shortness of breath;it also has the unique symptoms among various diseases. Invigorating Qi and promoting blood circulation is the basic treatment for the QDBSS. It is of significance to pay attention to"supplement by passing, combination of pass and supplement"and combine regulating Qi-flowing method with enriching blood method or aromatic warming method for QDBSS therapy according to the differ-ence of Zhengxie shengshuai.

Objective To explore the diagnostic value of MRE for differentiating hepatic benign and malignant tumors.Methods 36 patients with liver tumor (a total of 39 lesions,including 20 hepatocellular carcinomas,7 hemangiomas,5 cholangiocellular carcinomas,3 metastases,2 hepatic angiomyolipomas,1 carcinosarcoma,1 castleman’s disease)and 9 healthy volunteers were evaluated with MRE.The elastogram were generated with FUNCTOOL post processing program.The mean value of elasticity of hepatic malignant tumors,hepatic benign tumors,hepatic parenchyma around the malignant tumors,hepatic parenchyma around the benign tumors and the normal liver of healthy volunteers were measured and compared.Results The mean value of elasticity of malignant tumors [(7.39±1.70)kPa]was significantly higher than these of benign tumors [(4.11±0.37)kPa,P 0.05).A cutoff value of 5.08 kPa can accurately differentiate malignant tumors from benign tumors and normal liver parenchyma.Conclusion MRE could be used in diagnosis of hepatic focal tumors,which is helpful for differentiating benign and malignant liver tumors.

Objective To find the effective quantitative parameters for the differentiation of the breast lesions using the post-processing of time.signal curve of 3D dynamic-enhanced MRI.Methods Thirty patients with 35 lesions underwent 3D dynamic-enhanced MRI and the time-signal cHIve was deduced.The four quantitative parameters including SImax,PH,Slope and SlopeR were analyzed in benign andmalignant lesions of the breast.Independent samples t test and rank sum test were used for the statistics.Results Seyenteen benign lesions and 18 malignant lesions were included in this study.The SImax(M)of benign and malignant lesions were 375.2 and 158.1,the 95% confidence intervals of SImax were 278.2-506.0 and 160.5-374.8.The PH(M)of benign and malignant lesions were 114.4 and 87.8,the 95% confidence intervals of PH were 73.7-196.5 and 71.3-162.9.The Slope(M) of benign and malignant lesions were 22.3×10-3 and 44.0×10-3,the 95% confidence intervals of Slope were 13.7×10-3-41.1×10-3 and 46.1×10-3-81.8×10-3.The Slope"(M) of benign and malignant lesions were 2.6 and11.4,the 95% confidence intervals of SlopeR were 1.9-3.4 and 9.8-14.5.There were no significant differences on SImax and PH between benign and malignant lesions(P>0.05).The significant differences existed on Slope(P<0.01)and SlopeR(P<0.01)between benign and malignant lesions of the breast.Conclusion SlopeR is a very effective parameter in t}le differential diagnosis of breast lesions.

Objective To evaluate the value of MR spectroscopy (MRS) in the differential diagnosis between recurrence and radiation encephalopathy after radiotherapy for nasopharyngeal carcinoma (NPC). Methods Muhi-voxel proton MRS was performed on 50 patients with NPC, who were suspected of intracalvarium tumor recurrence or radiation encephalopathy after radiotherapy by conventional MRI,including 44 males and 6 females. Among the 50 patients, 26 cases were finally diagnosised as basicranial tumor recurrence and 24 cases as radiation encephalopathy by clinical and MRI follow-up. The following metabolites, such as Cho, NAA, Cr, lactate and lipid, were analyzed comparatively between basicranial tumor recurrence and radiation encephalopathy(RE), and between the lesions and the relative normal brain tissue. Wilcoxon's rank sum test was used to analyze the data. Results The median of Cho/Cr, Cho/NAA,LI/Cr in tumor recurrence group were 2. 22, 2. 13, and 1.77, respectively, and 1.40, 1.31, and 0. 57,respectively, in RE group. The difference of Cho/Cr, Cho/NAA, and LL/Cr between the two groups were statistically significant (P < 0. 01). Those in tumor recurrence group were higher than in RE group. The median of Cho, Cr, NAA in tumor recurrence group and in RE group were 3366. 00, 1023.00, 1930. 00 and 2469.50, 1864.50, 1734.00. There were no significant difference of Cho, Cr, and NAA between the two groups (P > 0. 05). In the 14 cases whose normal brain tissue were compared with the recurrent tumor tissue in tumor recurrence group, the median of Cr, NAA, LL, Cho/Cr, Cho/NAA, LL/Cr of recurrent tumor tissue and normal brain tissue were 1023.00, 1930.00, 2090.00, 3.76, 2. 13, 3.39 and 2370.00, 3012.00, 1680.00, 1.64, 1.17, 0.75,The difference of Cr, NAA, LL, Cho/Cr, Cho/NAA, LL/Cr between the normal tissue and recurrent tumor tissue were significant (P <0.05). LL, Cho/Cr, Cho/NAA, LL/Cr of recurrent tumors were higher than those of the normal brain tissue,while NAA and Cr of recurrent tumors were lower than those of the normal brain tissue. In the 12 cases whose normal brain tissue were compared with the RE tissue in RE group, the median of Cho, Cr, NAA, LL, Cho/Cr, IX,/Cr of RE tissue and normal brain tissue were 390.00, 217.50, 427.50, 39.00, 1.30, 0.40 and 680.00, 360.00, 610.00, 30.00, 1.54, 0. 09. The difference of above-mentioned parameters between RE tissue and normal tissue were significant. Cho, Cr, NAA, Cho/Cr of RE were lower than those of normal tissue (P <0. 05) ,while LL and LL/Cr of RE were higher than those of normal tissue (P < 0. 05). Conclusion The changes of the metabolites in recurrent lesions and RE lesions were different on MRS. Parameters such as Cho/Cr, Cho/NAA and LL/Cr, which were higher in recurrent lesions than those of RE, were valuable for the differential diagnosis between basicranial tumor recurrence and radiation encephalopathy after radiotherapy for NPC.
