A quantitative method using ultrahigh-performance liquid chromatography was established to simultaneously determine ten ginsenoside active ingredients including ginsenoside Rg6, F4, Rk3, Rh4, 20(S) -Rg3, 20(R) -Rg3, Rk1, Rg5, 20(S)-Rh2 and 20(R)-Rh2 in steamed notoginseng. The ten ginsenosides of steamed notoginseng with different head numbers, parts, and steaming time were determined by this method. An Acquity BEH C18 chromatographic column (2.1 mm x 100 mm, 1.7 microm) was used to perform the determination, which was maintained at 35 degrees C throughout the analysis. Mobile phase was composed of water and acetonitrile with flow rate at 0.3 mL x min(-1) under gradient elution, and detection wavelength was set to 203 nm for monitoring the separation. The results demonstrate ginsenoside Rg6, F4, Rk3, Rh4, 20 (S)-Rg3, 20 (R) -Rg3, Rk1, Rg5, 20 (S)-Rh2 and 20(R) -Rh2 have shown good linearity (R2 > or = 0.999 8) within 0.46-115, 2.06-515, 1.632408, 3.216-804, 1.392-348, 1.4-350, 0.496-248, 3.012-1 506, 0.82-205 and 0.832-208 mg x L(-1), and their average recoveries were 97.00%, 97.96%, 98.86%, 95.27%, 98.67%, 98.02%, 95.53%, 96.63%, 99.57% and 103.6%, respectively. The proposed approach was quick and accurate and portrayed excellent repeatability and determination efficiency. The quality of steamed notoginseng was effectively controlled, which served as a foundation for establishing a normalized processing technique and quality standard for ensuring the reliability and consistency of its clinical efficacy.

Objective To investigate the relationship between interleukin 1β( IL?1β) , interleukin?33 ( IL?33) , neutrophil?to?lymphocyte ratio ( NLR ) and atrial fibrillation. Methods Eighty?two patients with nonvalvular atrial fibrillation treated in the department of cardiology in the Fourth People′s Hospital of Jinan from October 2015 to October 2016 were enrolled in the study,including 43 patients with persistent atrial fibrillation and 39 patients with paroxysmal atrial fibrillation. 50 healthy subjects were selected as the control group. Enzyme linked immunosorbent assay (ELISA) was used to determine the concentration of IL?1βand IL?33,and the left atrial diameter ( LAD) was measured by echocardiography. Results ( 1) The concentrations of IL?1β,NLR and LAD in the paroxysmal atrial fibrillation group were (24. 44±4. 89) ng/L,(2. 51±1. 22) %,(36. 16± 6. 12) mm,the concentrations of IL?1β,NLR and LAD in the persistent atrial fibrillation group were (26. 95±5. 86) ng/L,(5. 7±1. 8) %,(39. 36±4. 78) mm and the values in the control group were (19. 53±4. 51) ng/L,(1. 82 ± 0. 41 ) %, ( 33. 31 ± 2. 89 ) mm, respectively. The differences among the three groups were statistically significant ( F=16. 74,11. 82,14. 85,P<0. 01) . The indexes of paroxysmal atrial fibrillation group and persistent atrial fibrillation group were higher than those of the control group ( P<0. 01 ) . ( 2 ) In the persistent atrial fibrillation group, NLR and LAD were ( 5. 7 ± 1. 8 )% , and ( 39. 36 ± 4. 78 ) mm, higher than those of the paroxysmal atrial fibrillation group ( (2. 51±1. 22)%,(36. 16±6. 12) mm),the differences were statistically significant ( P<0. 01) . However,the level of IL?1βin the persistent atrial fibrillation group was not significantly different from that in the paroxysmal atrial fibrillation group ( (26. 95±5. 86) ng/L vs. (24. 44±4. 89) ng/L,P>0. 05). (3) The concentrations of IL?33 in the paroxysmal atrial fibrillation group,atrial fibrillation group, control group were ( 48. 31 ± 4. 72 ) ng/L, ( 50. 03 ± 2. 18 ) ng/L, ( 56. 87 ± 5. 12 ) ng/L, respectively. The difference among the three groups has no statistical significance ( F=2. 52, P>0. 05 ) . ( 4 ) NLR level was positively correlated with LAD ( r=0. 32,P=0. 002) . There was no significant correlation among IL?1β,IL?33 and LAD ( r=0. 16, P=0. 11, r=0. 02, P=0. 37 ) . Conclusion The levels of IL?1β, NLR and LAD in peripheral blood of patients with atrial fibrillation were significantly higher than those in patients with sinus rhythm,and there was a positive correlation between NLR and LAD.

Objective To investigate the incidence of hearing disorder and analyse the high-risk factors with hearing injury in newborns with hyperbilirubinemia.Methods The newborns with hyperbilirubinemia who admitted to the department of neonate,were received the distortion product otoacoustic emission(DPOAE)test when they recovered from hyperbilirubinemia;those babies who didn′t pass the first test received screening again in 42 days after birth.Those babies who didn′t pass the second test received auditory brain stem response(ABR)test.Results Fifty-eight(33.2%)newborns didn′t pass the first DPOAE test among 235 newborns with hyperbilirubinemia;11(18.9%)infants didn′t pass the second DPOAE test among 58 infants;5 infants failed to pass the ABR test,the ratio of hea-ring disorder in newborns with hyperbilirubinemia was 2.13%;18(9.9%)newborns didn′t pass the first DPOAE test among 182 normal newborns,and those infants all passed the second DPOAE test.Conclusions Hyperbilirubinemia is high-risk population of hearing disorder.The congenital cytomegalovirus infection,neonatal septicemia and hemolytic disease of newborn are the high risk factors responsible for hearing disorder.All high risk newborns should recieve hearing examination regularly.

Objective To retrospectively evaluate the mammographic features of breast ductal carcinoma in situ (DCIS)and DCIS with small invasive foci,and to analyze the correlation between the mammographic findings and the prognostic biologic factors.Methods The mammographic examination was performed in 95 consecutive women with breast DCIS(n = 50)and DCIS with invasive foci(n = 45 ).The prognostic biologic factors including progesterone receptor(PR),C-erbB-2,and p53 were evaluated in 62 of 95 cases.Categorical data were expressed as percentages and analyzed by using the X~2 test,and furthermore the odds ratio was measured.Results(1)Only one abnormality was seen on mammography in 62 patients. Combined two abnormalities on mammography were seen in 26 patients.Mammograms were normal in 7 patients.(2)Calcifications with or without other abnormality were noted in 62 cases.Of them,73% (n =45)had higher probability of malignancy calcifications and the others were intermediate concern calcifications.Clustered calcifications(36 lesions)was the most common distribution,which usually accompanied by another abnormality.And then were segmental(18 lesions)distributed pattern.As far as the shape of mass (n = 22)was concerned,the oval shaped lesion(13 cases)was the most common,and the margin of the mass appeared as ill-defined in 15 eases,microlobulated in 1,circumscribed in 4,and obscured in 2,respectively.Isodensity mass had a higher frequency in this group(12/22,55%).Other non-calcification findings included architecture distortion(7 cases),local asymmetry (15 cases),global asymmetry (5 cases),and solitary dilated duct (3 cases),and most of them accompanied with other signs. (3)For expression profile of the biological factors,significant differences were found among malignant calcification group,intermediate concern calcification group,and non-calcification group. The odds of PR positive for the lesions noted as non-calcification were 11.00 times higher (X~2 =8.571 ,P=0.003 ;95% CI, 1.998—60.572)than the lesions noted as intermediate concern calcifications,and 8.80 times higher (X~2 = 9.748,P=0.002 ;95% CI,2.024—38.253)than the lesions noted as malignant calcifications.The odds of C-erbB-2 positive for the lesions showed as malignant calcifications were 12.35 times higher (X~2=7.353, P=0.007 ;95% CI,1.447—105.443)than the lesions showed as non-calcification,and 5.74 times higher (X~2=4.977,P = 0.026;95% CI,1.110—29.645)than the lesions showed as intermediate concern calcifications.Conclusion The mammographic features of DCIS and DCIS with small invasive foci were characteristic.Mammographic findings could be a prognostic markers,which could provide a possibility for making a treatment plan.

Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.
