Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

The present study explored the drying effect of new spiral vibration drying technology on Chinese medicinal pills with Liuwei Dihuang Pills, Zhuanggu Guanjie Pills, and Muxiang Shunqi Pills as model drugs. With the drying uniformity, drying time, energy consumption, pill split, dissolution time, and change of index components as evaluation indicators, the drying effect of spiral vibration drying technology on model drugs was evaluated and compared with traditional drying methods, such as hot air drying and vacuum drying in the oven. The dynamic changes of moisture in Liuwei Dihuang Pills with different drying time were investigated. Compared with the traditional drying methods in the oven(hot air drying and vacuum drying) at 80 ℃, the spiral vibration drying only took 80 min, shortened by 80%, with 10%-13% energy consumed. The results showed that the moisture of Liuwei Dihuang Pills was negatively related to the drying time. By virtue of multi-layer countercurrent drying and super resonant fluidization techniques, the new spiral vibration drying technology can significantly improve the drying quality of Chinese medicinal pills, improve the drying efficiency, and enhance the manufacturing capacity of Chinese medicinal pills. This study is expected to provide references for the innovation and development of new drying technology of Chinese medicinal pills.

OBJECTIVE:
To investigate the effect of silencing CD46 and desmoglein 2 (DSG2) in host A549 cells on the entry of human adenovirus type 3 (HAdV-3) and type 7 (HAdV-7) and host cell secretion of inflammatory cytokines.
METHODS:
RNA interference technique was use to silence the expression of CD46 or DSG2 in human epithelial alveolar A549 cells as the host cells of HAdV-3 or HAdV-7. The binding of the viruses with CD46 and DSG2 were observed with immunofluorescence staining at 0.5 and 1 h after viral infection. The viral load in the host cells was determined with qRT-PCR, and IL-8 secretion level was measured using ELISA.
RESULTS:
In infected A549 cells, immunofluorescent staining revealed colocalization of HAdV-3 and HAdV-37 with their receptors CD46 and DSG2 at 0.5 h and 2 h after infection, and the copy number of the viruses increased progressively after the infection in a time-dependent manner. In A549 cells with CD46 silencing, the virus titers were significantly lower at 2, 6, 12 and 24 h postinfection in comparison with the cells without gene silencing; the virus titers were also significantly decreased in the cells with DSG2 silencing. The secretion level of IL-8 increased significantly in A549 cells without siRNA transfection following infection with HAdV-3 and HAdV-7 (P < 0.0001), but decreased significantly in cells with CD46 and DSG2 silencing (P < 0.0001).
CONCLUSION
HAdV-3 and HAdV-7 enter host cells by binding to their receptors CD46 and DSG2, and virus titer and cytokines release increase with infection time. Silencing CD46 and DSG2 can inhibit virus entry and cytokine IL-8 production in host cells.

BACKGROUND/AIMS: A large number of studies have shown that function constipation (FC) has an extremely high incidence of mental and psychological disorders. Cranial electrotherapy stimulation (CES) was applied to the treatment of psychological disorders such as anxiety and depression. We explored the effects of CES combined with biofeedback therapy (BFT) on the psychological state, clinical symptoms, and anorectal function in patients with FC. METHODS: A total of 74 patients with FC were randomly divided into 2 groups. The control group received BFT. CES combined with BFT was carried out in the experiment group. All patients were assessed using the self-rating anxiety scale (SAS), self-rating depression scale (SDS), and Wexner constipation score at baseline and the end of each course. Anorectal manometry and balloon expulsion tests were performed before and after treatment. RESULTS: After treatment, the participants in the experiment group had significantly lower score SAS, SDS, and Wexner constipation scores than the control group (all P < 0.05). The number of successful expulsion in the experiment group was larger than the control group (P = 0.016). CONCLUSIONS: CES combined with BFT was effective in improving the psychological status of anxiety, depression, and bowel symptoms in patients with FC.

β-Amyrin synthase (β-AS) genes of Glycyrrhiza uralensis from 6 different regions were analyzed by PCR-SSCP and sequenced, then the correlationship between β-AS SNP and regions of Glycyrrhiza uralensis were determined. According to the 1 coding single nucleotide polymorphism on the first exon of β-AS gene at 94 bp site, Glycyrrhiza uralensis could be divided into 3 genotypes. In these genotypes, the percentage of 94A type in genuine regions was much higher, and it had significant differences with the percentage in non-genuine regions (P < 0.001). The results of the experiment proved that different β-AS genotypes at 94 bp site from different regions may be one of the important reasons to result in the genuineness of Glycyrrhiza uralensis.

The fruit of Lycium ruthenicum is a common folk medicine in China. Now it is popular for its antioxidative effect and other medical functions. The adulterants of the herb confuse consumers. In order to identify a new adulterant of L. ruthenicum, a research was performed based on NCBI Nucleotide Database ITS Sequence, combined analysis of the origin and morphology of the adulterant to traceable varieties. Total genomic DNA was isolated from the materials, and nuclear DNA ITS sequences were amplified and sequenced; DNA fragments were collated and matched by using ContingExpress. Similarity identification of BLAST analysis was performed. Besides, the distribution of plant origin and morphology were considered to further identification and verification. Families and genera were identified by molecular identification method. The adulterant was identified as plant belonging to Berberis. Origin analysis narrowed the range of sample identification. Seven different kinds of plants in Berberis were potential sources of the sample. Adulterants variety was traced by morphological analysis. The united molecular identification-origin-morphology research proves to be a preceding way to medical herbs traceability with time-saving and economic advantages and the results showed the new adulterant of L. ruthenicum was B. kaschgarica. The main differences between B. kaschgarica and L. ruthenicum are as follows: in terms of the traits, the surface of B. kaschgarica is smooth and crispy, and that of L. ruthenicum is shrinkage, solid and hard. In microscopic characteristics, epicarp cells of B. aschgarica thickening like a string of beads, stone cells as the rectangle, and the stone cell walls of L. ruthenicum is wavy, obvious grain layer. In molecular sequences, the length of ITS sequence of B. kaschgarica is 606 bp, L. ruthenicum is 654 bp, the similarity of the two sequences is 53.32%.

OBJECTIVETo investigate the expression level of SOX11 mRNA in mantle cell lymphoma (MCL) and other B-cell non-Hodgkin lymphoma (B-NHL) and its prognostic value in MCL.
METHODSThe expression level of SOX11 mRNA in 80 B-NHL patients were determined by real-time quantitative RT-PCR, GAPDH was used as internal control. The dispersion of SOX11 expression ratio of groups with different prognostic factors was described by Mann-Whitney U test.
RESULTSThe SOX11 mRNA expression level was 2.90 (0.75 - 4.63) in 80 B-NHL patients, and the expression level was significantly higher in MCL than that in other B-NHL (P = 0.014). The SOX11 expression level was statistically lower in the group of MCL with hyperleukocytosis, 12 trisomy, MYC amplification and therapeutic effect < PR (P = 0.042, 0.013, 0.028, 0.009) than that of MCL in other group. But SOX11 expression was not associated with MCL international prognostic index (MIPI) (P = 0.333), lactate dehydrogenase (LDH) (P = 0.790), ATM mutation (P = 0.865) and P53 deletion (P = 0.116). The progression free survival (PFS) and overall survival (OS) were significantly longer in the MCL patients with high level of SOX11 than that of other MCL patients.
CONCLUSIONThere was statistically significant differences in SOX11 mRNA expression between MCL with other B-NHL. SOX11 maybe a good prognostic factor in MCL.
