Though parched Chinese herbal medicines contain less effective or index components, their pharmacological actions do not reduce or even become improved to some extent. However, the current studies related to material basis could not explain the changes in property, flavour and efficacy of parched Chinese herbal medicines. Meanwhile, due to the lack of objective and specific evaluation indexes, the quality evaluation could not reflect features of parched Chinese herbal pieces. Therefore, how to break the bottleneck for the studies on parched Chinese herbal pieces, make further innovation and conduct in-depth studies on the material basis of parched Chinese herbal medicines are common problems that medical scholars are facing. According to the findings in the previous studies, the author proposed to explain the material basis of parched Chinese herbal medicines by studying Maillard reaction and establish specific quality evaluation indexes according to the features of parched Chinese herbal pieces, and conducted relevant studies.

Background The double kissing (DK) crush technique is a modified version of the crush technique.It is specifically designed to increase the success rate of the final kissing balloon post-dilatation,but its efficacy and safety remain unclear.Methods Data were obtained from the DKCRUSH-I trial,a prospective,randomized,multi-center study to evaluate safety and efficacy.Post-procedural and eight-month follow-up intravascular ultrasound (IVUS) analysis was available in 61 cases.Volumetric analysis using Simpson's method within the Taxus stent,and cross-sectional analysis at the five sites of the main vessel (MV) and three sites of the side branch (SB) were performed.Impact of the bifurcation angle on stent expansion at the carina was also evaluated.Results Stent expansion in the SB ostium was significantly less in the classical crush group ((53.81±13.51)％) than in the DK crush group ((72.27±11.46)％) (P=-0.04).For the MV,the incidence of incomplete crush was 41.9％ in the DK group and 70.0％ in the classical group (P=-0.03).The percentage of neointimal area at the ostium had a tendency to be smaller in the DK group compared with the classical group ((16.4±19.2)％ vs.(22.8±27.1)％,P=-0.06).The optimal threshold of post-procedural minimum stent area (MSA) to predict follow-up minimum lumen area (MLA) ＜4.0 mm2 at the SB ostium was 4.55 mm2,yielding an area under the curve of 0.80 (95％ confidence interval:0.61 to 0.92).Conclusion Our data suggest that the DK crush technique is associated with improved quality of the final kissing balloon inflation (FKBI) and had smaller optimal cutoff value of post-procedural MSA at the SB ostium.

OBJECTIVETo observe the clinical effect of Huikangling Tablet (HT, extracted from Scabrous Patrinia root) on peripheral blood micrometastasis of differentiated thyroid carcinoma (DTC) patients.

METHODSTotally 87 DTC patients with positive micrometastasis were randomly assigned to the treatment group (45 cases) and the control group (42 cases). DTC endocrine inhibition treatment standards were executed in all patients. They all took levothyroxine sodium (50 microg/tablet, from low dose, 25 microg each time, once per day, 0.5 h before breakfast), and its dosage was gradually added one week later. The dosage was adjusted according to tested results of TSH combined recurrence risk stratification and endocrine suppression induced adverse reactions risk stratification. Patients in the treatment group took HT (0.4 g per tablet, 3 tablets each time, three times per day for a total of 12 weeks) combined TSH suppression therapy, while those in the control group only received TSH suppression therapy. Peripheral micrometastatic cytokeratin 19 (CK19) and polymorphic epithelial mucin1 (MUC1) were detected by FCM at week 4 and 12. Meanwhile, distant metastasis and adverse reactions were observed.

RESULTSAfter 4-week treatment positive micrometastasis was shown in 18 cases (40%) of the treatment group and 29 cases (69%) in the control group with statistical difference (chi2 = 5.68, P < 0.05). After 12-week treatment positive micrometastasis was shown in 7 cases (15.6%) of the treatment group and 17 cases (44.7%) in the control group with statistical difference (chi2 = 8.49, P < 0.01). Pulmonary metastasis occurred in 2 cases and bone metastasis in 1 case of the control group at follow-ups. Cervical lymph node metastasis without accompanied recurrence of thyroid cancer occurred in one case of the treatment group. No obvious liver or renal abnormalities occurred.

CONCLUSIONHT inhibited peripheral blood micrometastasis of DTC patients and its mechanism needed to be further studied.
