Objective To explore surgical management of bilateral thyroid papillary carcinoma. Methods The clinical data of 55 patients with bilateral thyroid papillary carcinoma were analyzed retrospectively. Among the 55 patients, total thyroidectomy was performed in 52 cases, total affected lobectomy plus isthmus and opposite near total lobectomy thyroidectomy was performed in 3 cases. Results Among the cases of bilateral functional neck lymph node dissection ,5 cases were all of bilateral neck lymph node metastasis, the positive rate was 100.0%(5/5);, among the cases of unilateral functional neck lymph node dissection,9 cases were found neck lymph node metastasis,the positive rate was 81.8%(9/11); among the cases of bilateral central region lymph node dissection, 1 case was of central region lymph node metastasis, the positive rate was 25.0% (1/4); among the cases of unilateral central region lymph node dissection, 14 cases were of central region lymph node metastasis, the positive rate was 66.7%(14/21). Fifty-three cases were tumor free survival, 2 cases accompanied distant metastasis also gained good effect Conclusions Total thyroidectomy should be performed for bilateral thyroid papillary carcinoma because of its characteristics of multiple tumors. It is considered that whether the neck lymph node dissection should be done depends on the stage of the tumor.

Methods Expression of Tbx3 gene in 53 specimens of breast cancer and 28 specimens of normal breast tissues were investigated by immunohistochemistry, analysing the clinical significance. Meanwhile the correlation of expression of Tbx3 gene in breast cancer classified was investigated by estrogen receptor ( ER),lymph node metastasis, Her-2 status. Results Positive rate of Tbx3 gene in breast cancer tissues was significantly higher than that in normal breast tissues [73.58% (39/53) vs 14.29% (4/28)] (P < 0.05).Positive rate of Tbx3 gene in ER positive breast cancer tissues was higher than that in ER negative breast cancer tissues [ 84.38% (27/32) vs 57.14% ( 12/21 ) ] (P < 0.05 ). Positive rate of Tbx3 gene in breast cancer tissues with lymph node metastasis was higher than that in breast cancer tissues without lymph node metastasis [86.21%(25/29) vs 58.33% (14/24) ] (P < 0.05). Positive rate of Tbx3 gene in Her-2 positive breast cancer tissues was higher than that in Her-2 negative breast cancer tissues[ 93.75%(15/16) vs 64.86% (24/37) ] (P < 0.05). Conclusions Tbx3 gene is over expressed in breast cancer tissues. It is related to ER, lymph node metastasis, Her-2 status.

OBJECTIVE:To establish a method for simultaneous determination of 18 toxic elements from 10 ingredients of Modified xiaoyao formula and their extracts,and to study transport rates of above elements. METHODS:Microwave digestion-in-ductively coupled plasma mass (ICP-MS) was used to determine above elements. Radio-frequency power was 1.50 kW,atomiza-tion pressure was 720 kPa,sampling depth was 7 mm,plasma gas flow rate was 15.0 L/min,carrier gas flow rate was 1.00 L/min, spray chamber temperature was 2℃,He flow rate was 4.5 mL/min under collision mode,measurement points/peak was 3,data ac-quisition mode was jump mode. RESULTS:The linear ranges of As,Pb,Cu,Hg,Cd,Mo,V,Cr,Mn,Fe,Ni,Zn,Ru,Rh, Pd,Os,Ir,Pt was 0-500.17 ppb(r was 0.9994-09999);LOD was 0.0004-5.3410 ng/g;RSD of repeatability tests was all lower than 5.0%;average recoveries were 82.0%-117.9%(RSD=0.2%-5.7%,n=9). Ru,Rh,Pd,Os,Ir,Pt,Hg had not been detect-ed. The transfer rates of 11 metals in the extracts ranged 1.46%-31.90%. CONCLUSIONS:The method is simple,precise,stable and repeatable,and can be used for simultaneous determination of 18 toxic elements in 10 ingredients of Modified xiaoyao formula and their extracts. The contents of toxic elements are decreased during the preparation of Modified xiaoyao formula extract to guar-antee the safety of drug use to certain extent.

OBJECTIVETo investigate the quality of Schisandra chinensis, and thus provide the useful reference data for its quality standard establishment and standardized cultivation.
METHODBase on the Chinese Pharmacopoeia and literature relating to S. chinensis, the appearance, water-soluble extractive, total ash, acid-insoluble ash and volatile oil of 10 S. chinensis sampes collected from different producing sites in northeast China were studied or determined, and the contents of major active lingans were measured by HPLC.
RESULTThe content of total ash and acid-insoluble ash in S. chinensis was less than 7.0%, 1.0%, respectively. The contents of water-soluble extractive were higher than 45.0%. HPLC analyses showed that the content of schisandrol A was higher than 0.40%. All these results in accordance with the requirements of Chinese Pharmacopoeia were published in 2010.
CONCLUSIONThe differences of the appearance and the internal quality are different for the samples collected from different areas. And the establishment of a scientific and comprehensive quality standard system will be very important role in ensuring the quality of S. chinensis.

OBJECTIVETo determine the residues of organochlorine pesticides and heavy metals in Radix Ophiopogonis and Ophiopogon japonicus.
METHODThe residues of 4 isomers of benzene hexa chloride (BHC) and 4 isomers of dichloro dipheny trichloroethane (DDT) were determined by gas chromatography. The contents of Pb, Cd, Cu, Cr, Hg and As were determined by ICP.
RESULTThe residues of organochlorine pesticides in Radix Ophiopogonis were lower than the permissible maximum limits of the Chinese national standard except hexachloride (BHC) in Radix Ophiopogonis from Cixi as well as Cu in soil of Luojiang.
CONCLUSIONThe enrichment capacity of Radix Ophiopogonis for (BHC) and Hg is higher. It is suggested that we should try to select herbs-growing soil for O. japonicus with a particular emphasis on the pesticides residues in soil.

OBJECTIVE:To investigate the compatibility stability of Salvianolic acid for injection (SAFI) combined with 8 kinds of common solvents. METHODS:Referring to package inserts,SAFI was collected and combined with 0.9% Sodium chlo-ride injection,5% Glucose injection,10% Glucose injection,Compound sodium chloride injection,Mannitol injection,Glycerol fructose and sodium chloride injection,Sodium lactate Ringer's injection,Glucose and sodium chloride injection,250 mL each re-spectively,and then sealed in the dark at the room temperature. The appearance of mixtures were observed,pH value,the number of insoluble particles,maximal absorption wavelength and maximal absorbance were detected,and the contents of salvianolic acid B,rosmarinic acid,lithospermic acid and salvianolic acid Y in mixtures were determined by HPLC at 0,1,2,4,8 h after mix-ing. RESULTS:Under above condition,no obvious change was found in appearance or pH values of the mixtures within 8 h. Maxi-mal absorption wavelength ranged 284.5-286.0 nm. After mixed with Mannitol injection,the number of particles≥10μm(1-8 h af-ter mixing)and particles ≥25 μm(4-8 h after mixing)exceeded the scope of Chinese Pharmacopoeia(2015 edition);the maxi-mal absorbance changed significantly(RSD=9.17%,n=5);the relative content of salvianolic acid B,rosmarinic acid,lithosper-mic acid and salvianolic acid Y decreased by more than 10%(RSD=14.65%,6.45%,8.97%,12.49%,n=5);after mixed with Sodium lactate Ringer's injection,the relative content of rosmarinic acid and lithospermic acid changed greatly (RSD=14.57%, 7.28%,n=5);after mixed with 5% Glucose injection(4-8 h after mixing)and Glycerol fructose and sodium chloride injection(8 h after mixing),the relative content of rosmarinic acid were less than 90%(RSD=6.30%,4.86%,n=5);and the number of particles ≥25μm exceeded the scope of phamcopoeia after mixing with Glycerol fructose and sodium injection(0 h). The number of insoluble particles in other mixtures were in line with the standard of pharmacopoeia;maximal absorbance had no significant change(RSD<5%,n=5),and the relative content change of analytes were all less than 10%. CONCLUSIONS:Clinical appli-cation of SAFI combined with Mannitol injection,Sodium lactate Ringe's injection and Glycerol fructose and sodium injecrion should be avoided. After mixed with 5% Glucose injection,SAFI should be used within 4 h. SAFI can be compatible with 0.9%Sodium chloride injection,10% Glucose injection,Compound sodium chloride injection and Glucose and sodium chloride injec-tion.
