Objective To screen serum proteomic marker of hepatic echinococcosis, establish a diagnotic model of serum protein fingerprint patterns, and evaluate its clinical application for hepatic echinococcosis. Methods Serum samples from 68 patients with hepatic echinococcosis matched with 73 controls composed of 33 patients with liver diseases other than hepatic echinococcosis and 40 healthy people were collected. All subjects were divided into training group (37) and testing group (67). Serum protein profiling of patients with hepatic echinococcosis and controls were detected using surface enhanced laser desorption/ionization time of flight mass spectrometry(SELDI-TOF-MS) and weak cation exchange protein chip(WCX2). Peak intensities were compared, in the training group, between 37 patients with hepatic echinococcosis and 37 controls, 5 patients with HCE and 5 patients with HAE, and 8 patients with hepatic echinococcosis before and after operation, respectively. ZJU-Protein Chip Data Analyze System(ZJU-PDAS) was used for data analysis and the model of serum protein fingerprint patterns was build by support vector machine (SVM). The sensitivity and specificity of the model for diagnosis of hepatic echinococcosis were verified by blind method on samples of testing group. Results There were nine different protein peak spectra between hepatic echinococcosis group and control group, of which eight protein peak spectra decreased in patient group, their relative molecular mass were 1044, 1047, 1073, 1075, 1338, 6453, 6649, 8714 m/z, respectively, while one protein peak spectrum(5651 m/z) increased(P < 0.05). The sensitivity,specificity, positive predictive and negative predictive value of the model validated by blind method were 77.4% (24/31), 66.7% (24/36), respectively. There were two different protein peak spectra between HCE group and HAE group, Their relative molecule mass were 8716 and 2751 m/z, respectively (P < 0.05). Six different proteins were detected from pre-operation group and post-operation group. Their relative molecular mass were 1297, 1505, 1525, 1534, 5921, 5941 m/z, respectively(P < 0.05). Conclusions It is a successful way to screen serum proteomic marker in patients with hepatic echinococcosis by SELDI-TOF-MS and Bio-informatics, and the marker has a potential clinical value in diagnosis and judging prognosis of hepatic echinococcosis.

Methods Coding sequences of capsid proteins of WU polyomavirus by PCR were cloned in prokaryotic expression vector PGEX-20T. Recombinant plasmids were transformed into E. coli BL21(DE3) and induced by IPTG for proteins expression. Recombinant proteins were identified by Western blot. Results SDS-PAGE proved that recombinant proteins showed three bands with molecular relative mass of 69×103, 63×103 and 56×103. The recombinant proteins were recognized by anti-GST McAb. The antigenicity was tested by Western blot using 16 WU polyomavirus positive and 70 negative sera. Conclusion Recombinant VP1, VP2 and VP3 expressed in E. coli can combine with WUPyV-Ab and have good antigenicity. They can be used for further research.

Objective To evaluate the clinical effect of the homemade traditional Chinese medicine bathing prescription combined with Thymalfasin and Isotretinoin treatment for Verruca Plantaris.Methods A total of 120 patients with Verruca Plantaris were randomly divided into 3 groups according to the random number table method (each group 40). The drug therapy group was given Thymalfasin and Isotretinoin to treatment; and the Chinese medicine washing group was given traditional Chinese medicine wash-out on the basis of drug therapy; and the physical therapy group was given liquid nitrogen freezing treatment on the basis of drug therapy. All the groups were treated 12 weeks and follow-up 3 months. Four weeks were a course, and a total of 3 courses. After the treatment, the symptom grading scores (number of skin lesions, the size of skin lesions, the degree of pain and the quality of life) was compared, and the clinical effect rate was evaluated and the recurrence rate was observed.Results Twelve weeks after treatment, Chinese medicine washing group total effective rate was 97.5% (39/40), drug treatment group 87.5% (35/40), and physical treatment group 90.0% (36/40). The Chinese medicine washing group total effective rate was superior to the drug therapy and physicaltherapy groups (Z values were -3.463,-3.122,P values were 0.001, 0.002). after treatment, the number of lesions scores (2.0 ± 1.1 vs. 2.8 ± 1.5, 2.7 ± 1.6,F=3.787), the size of the lesion scores (2.3 ± 1.7 vs. 3.2 ± 1.3, 3.1 ± 1.3, F=4.657), pain degree and the quality of life scores (0.4 ± 0.5 vs. 1.0 ± 1.2, 1.0 ± 1.0,F=5.353) in the Chinese medicine washing group were significantly higher than those in the drug therapy and physical therapy groups (P<0.01). After follow-up period, the recurrence rate of Chinese medicine washing group was 10.3% (4/39), the drug treatment group 25.7% (9/35), the physical therapy group 41.7% (15/36). The difference among 3 groups was statistically significant (Z=-3.188,P<0.01).Conclusions The traditional Chinese medicine combined with Thymalfasin and Isotretinoin could reduce the number of skin lesions, narrow the range of skin lesions and reduce the degree of pain, and improve the quality of life.

Objective To clarify the role of syk kinase in inflammasome activation in mouse peritoneal macrophages during Listeria monocytogenes (LM) infection. Methods Murine peritoneal macrophages were randomly divided into BAY treatment group, SB treatment group, WO treatment group, no treatment group and negative control group (NI). There were three wells in each group. The syk inhibitor BAY 117082, P38MAPK inhibitor SB203580 and PI3K inhibitor wotamine were used to treat murine peritoneal macrophages for 1h in BAY treatment group, SB treatment group and WO treatment group. Murine peritoneal macrophages were infected with LM for 24 h except NI group. The protein level of interleukin (IL)-18 in the supernatant was detected by ELISA kit. The activation condition of key molecule ASC in the infected-macrophages cyto-plasm was observed under fluorescence microscope. The phosphorylation levels of syk protein kinase at different time points during LM infection were determined by Western blot assay. Results There was no significant difference in IL-18 protein level before and after BAY treatment in NI group (P>0.05). The IL-18 protein level was significantly lower after LM infec-tion in BAY treatment group compared with that in no treatment group (P<0.05). In contrast, there was no significant differ-ence in IL-18 production between SB treatment group, WO treatment and no treatment group (P>0.05). Meanwhile, the per-centage of ASC-speck positive cells was obviously diminished in BAY treatment group compared with that in no treatment group (P<0.01). The phosphorylation levels of syk were significantly increased in 5 min, 15 min and 30 min post-infection. Conclusion Syk kinase signaling is involved in the inflammasomes activation upon Listeria monocytogenes infection in mu-rine macrophages.

The present study identified chemical constituents of Honghua Xiaoyao Tablet (HXT) and explored its biological connotation and characteristics on the premenstrual syndrome (PMS) treatment from the "disease-syndrome-symptom" association network. UHPLC-Q Exactive Orbitrap HRMS technology was applied to analyze the chemical constituents in HXT. According to the composition principles, the compatible herbs of HXT were divided into the Shugan Jieyu group, Huoxue Tiaojing group and Yiqi Jianpi group. The candidate targets of the corresponding prescriptions of HXT efficacy groups were collected from the Pharmmapper database and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine (TCMIP) v2.0. The gene set related to the clinical symptoms included in Traditional Chinese and Western Medicine diagnosis and treatment standards were obtained from SoFDA, GeneCards, DisGeNET, MalaCards and literature published. The "HXT candidate targets-PMS (liver depression, Qi stagnation, and blood stasis syndrome) genes" network was constructed based on the gene interaction information, and further, the core network targets were screened out by topological characteristics of calculating network, and the functional exploration was carried out based on Kyoto Encyclopedia of Genes and Genomes (KEGG) for exploring the therapeutic advantages in PMS treatment of HXT efficacy groups, which were further verified experimentally in vitro. A total of 109 components from HXT were identified, including 20 components from Shugan Jieyu group enriched in the neurological system, estrogen regulation, and "immune-inflammation" related pathways, 77 components from Huoxue Tiaojing group enriched in the blood-circulation system, "immune-inflammation" and estrogen regulation related pathways and 30 components from Yiqi Jianpi group regulating immune inflammation, digestive system, and hormone levels. The biochemical indicator detection demonstrated that both the levels of 5-HT and DA in the hypothalamus tissues and the levels of E₂, NO, VEGF and RLN in the uterine tissues of PMS model rats were lower than those in controls, which the levels of OT, PROG, IL-6, IL-1β and TNF-α in the uterine tissues were increased in PMS group, which were all reversed by the administration of HXT, indicating that this prescription may regulate the synthesis and secretion of estrogen, intervene in neurotransmitter synthesis and signal transduction, reverse the imbalance of "immune-inflammation", and regulate digestive system function through various biological pathways, exerting the liver-smoothing, Qi-regulating, blood-activating and spleen-tonifying comprehensive effects, leading to alleviating the "neuroendocrine-endocrine-immune" system and blood-circulation disorders. The relevant results may provide a reference for clarifying the advantages and efficacy of HXT in treating PMS with liver stagnation, Qi stagnation, and blood stasis syndrome, and exploring its therapeutic advantages. The animal experiment of this study was approved by the Ethics Committee of the Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences (approval number: 2023B248).
