Licorice has long been regarded as one of the most popular herbs, with a very wide clinical application range. Whether being used alone or as an ingredient in prescription, it has an important role which cannot be ignored. However, the efficacy and chemical constituents of licorice will change after honey-processing. Therefore, it is necessary to find quality markers before and after honey-processing to lay the foundation for a comprehensive evaluation of the differences between raw and processed licorice pieces. HPLC-DAD was employed to establish fingerprints of raw and processed licorice. Multivariate statistical analysis methods including principal component analysis(PCA) and orthogonal partial least squares discrimination analysis(OPLS-DA) were applied to screen out the differential components before and after processing of licorice. Based on network pharmacology, the targets and pathways corresponding to the differential components were analyzed with databases such as Swiss Target Prediction and Metascape, and the "component-target-pathway" diagram was constructed with Cytoscape 3.6.0 software to predict the potential quality markers. A total of 17 common peaks were successfully identified in the established fingerprint, and seven differential components were selected as potential quality markers(licoricesaponin G2, glycyrrhizic acid, liquiritigenin, liquiritin, isoliquiritin, liquiritin apioside and isoliquiritigenin). The HPLC fingerprint method proposed in this study was efficient and feasible. The above seven differential chemical components screened out as potential quality markers of licorice can help to improve and promote the overall quality. These researches offer more sufficient theoretical basis for scientific application of licorice and its corresponding products.

Objective: To assess the effect of traversing the vertical pedicle flap (TVPF) for the treatment of severely buried penis in children. METHODS: Totally 43 children with severely buried penis underwentTVPF (n = 21)or modifiedShiraki surgery (control, n = 22) in our hospitalfrom February to December 2014. Wecompared the operation time, intra-operation blood loss, foreskin swelling time, and parents' satisfaction with penile appearance between the two groups. RESULTS: No statistically significant differences were observed between the TVPFand control groups in the operation time (［45.0 ±6.8］ vs ［42.0 ±5.3］ min, P>0.05) or intra-operation blood loss(［5.0 ±1.2］ vs ［6.0 ±0.8］ ml, P>0.05). The average foreskin swelling time was markedly shorter in the TVPFgroup than in the control (［9.0 ±2.3］ vs ［15.0 ±4.8］ d, P<0.05)and the parents' satisfaction with penile appearancewas higher in the former than in the latter (95.23vs31.81 %, P<0.05). The elastic bandages were removedfor all the patientsat 3 days postoperatively, and 3 to 6-month follow-up revealed no penile retraction or relapse. CONCLUSIONS The method of traversing the vertical pedicle flap is a feasible surgical option for the treatment of severely buried penis in children, which can make a rational use of the foreskin,remove the tight ring, and achieve a satisfactory appearance of the penis.

BACKGROUND: Psoriasis is an autoimmune disease that is caused by a shift in the Th1/Th2 balance toward Th1-dominant immunity. It has been established as an effective treatment to counteract psoriasis by subcutaneous injection of recombinant interleukin (IL)-4, and IL-4 gene therapy by topical transdermal penetration has shown its antipsoriatic effect in mice. Retinoic acid (RA) and dimethylsulfoxide can increase the efficiency of gene transfection in the topical transdermal delivery system. OBJECTIVE: We investigated whether RA could improve anti-psoriasis efficiency using IL-4 expression plasmid pORF-mIL-4 (pIL-4) via transdermal delivery system in K14-vascular endothelial growth (K14-VEGF) factor transgenic mice. METHODS: After pretreatment with RA, plasmid pIL-4 in 10% dimethylsulfoxide was applied to the ear skin by topical transdermal penetration. Hematoxylin- eosin staining and immunohistochemistry were performed with ear samples to evaluate anti-psoriasis efficiency in mice. RESULTS: The psoriasis pathological features were relieved and psoriasis-associated factors were significantly reduced. CONCLUSION: Our results reveal that topical application of pIL-4 in dimethylsulfoxide by transdermal delivery with RA pretreatment can improve psoriasis significantly.

Metabonomics is a new method to study on the metabolic network and the relationship between body and environment, which conforms to the way of traditional Chinese medicine (TCM) research. In the study process of modernization of traditional Chinese medicine, effectively conjunction with metabonomics method will facilitate the integration of TCM with modern biological science and technology, and promote the modernization of TCM. This paper introduce the application of metabonomics in the research of toxicity mechanism of TCM, compatibility mechanism of TCM formula, pharmacology effect of TCM and processing mechanism of TCM. This paper summarize the problems in the TCM metabonomics research and prospect its bright future.

OBJECTIVETo evaluate the clinical efficacy and safety of treatment of chronic primary glomerulopathy (CPG) patients of Shen deficiency and dampness heat syndrome (SDDHS) by Yishen Qingli Granule (YQG) combined with low-dose Tripterygium Wilfordii multiglycoside Tablet (TWT).

METHODSTotally 231 CPG patients of SDDHS were enrolled in this study (including 60 patients from First Affiliated Hospital of Nanjing University of Chinese Medicine, 58 from First Affiliated Hospital of Nanjing Medical University, 46 from Xinqiao Hospital of Third Military Medical University, 35 from First Affiliated Hospital of Guangzhou University of Chinese Medicine, 14 from First Affiliated Hospital of Soochow University, and 18 from Wuxi Affiliated Hospital of Nanjing University of Chinese Medicine). They were randomly assigned to the control group (116 cases) and the trial group (115 cases) according to block group method. There were 217 cases in the safety analysis set (109 cases in the trial group vs 108 cases in the control group), and 203 cases in the full analysis set (99 cases in the trial group vs 104 cases in the control group). All patients received basic treatment such as ACEI/ARB. Furthermore, YQG (consisting of raw astragalus 10 g, prepared Polygonum Multiflorum 10 g, Pyrrosia 10 g, 1.5 g each package, containing 10 g of crude drugs) was additionally given to patients in the trial group, each package, twice daily. The TWT (10 mg) was given, twice a day. The TWT dose was adjusted according to 24 h urinary total protein (UTP). The placebos of YQG and TWT were administered to those in the control group. The treatment course consisted of 24 weeks and the follow-up visit lasted for 24 weeks. The biochemical indices were observed before and after treatment including 24 h UTP, urine red cell count (U(RBC)), renal functions (BUN, SCr), blood routine test (WBC), and liver functions (SGPT, SGOT). Reverse reactions such as gastrointestinal discomfort, skin rash, and irregular menstruation were also observed.

RESULTSCompared with the control group, the total effective rate was better in the trial group (82.83% vs 61.54%, P < 0.01). Results of stratified comparison of UTP showed better efficacy in the trial group (0.8-3.0 g/24 h, P < 0.01). The UTP decline occurred in the trial group after 8 weeks of treatment, with stable action, showing statistical difference when compared with the control group (P < 0.01). In the trial group, U(RBC) level decreased after treatment but changed more significantly. But there was no statistical difference in the changes when compared with the control group (P > 0.05). After treatment, there were no statistical difference in safety indicators such as WBC, SGPT, and SGOT between the two groups after treatment (P > 0.05).

CONCLUSIONOn the basis of basic treatment such as ACEI/ARB, application of YQG combined with low-dose TWT had better effect in controlling proteinuria of CPG patients, and could help stabilizing their conditions with less adverse reactions.
