Objective:To explore the material basis and mechanism of Sangjiang Ganmao injection （SG） in the treatment of common cold by ultra-performance liquid chromatography-quadrupole/electrostatic field orbitrap high resolution mass spectrometry （UPLC-Q-Orbitrap HRMS） and network pharmacology. Method:UPLC-Q-Orbitrap HRMS was used to identify the chemical components of SG with mobile phase of acetonitrile （A）-0.1% formic acid aqueous solution （B） for gradient elution （0-10 min， 4%-15%A； 10-35 min， 15%-30%A； 35-45 min， 30%-33%A； 45-55 min， 33%-60%A； 55-58 min， 60%A）， flow rate of 0.2 mL·min^-1， electrospray ionization （ESI） and scanning range of m/z 100-1 500 under positive and negative ion modes. Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and GeneCards 5.0 database were used to screen and predict the potential targets of chemical components in SG， STRING 11.0 database and Cytoscape 3.7.2 software were used to construct protein-protein interaction （PPI） network model， gene ontology （GO） analysis and pathway analysis were performed on potential targets by Metascape 3.5， Reactome database and Kyoto Encyclopedia of Genes and Genomes （KEGG）， Cytoscape 3.7.2 software was used to build the network of "herbs-ingredients-key targets". Result:A total of 54 components in SG were identified， and 80 potential targets of SG for treatment of common cold were predicted and screened based on this. SG exerted therapeutic effects by acting on targets such as interleukin （IL）-6， tumor necrosis factor （TNF） and IL-10， and signaling pathways such as IL-17 signaling pathway， TNF signaling pathway and interaction of cytokine receptors. Conclusion:SG may interfere with the expression of inflammatory cytokines by acting on related targets and pathways such as inflammation and immune system， and regulate the immune function of the body as a whole， thereby exerting a therapeutic effect.

Objective To discuss the application value of CT scanning technology in cause of death determination of medical dispute cases. Methods From July 2017 to December 2018, postmortem CT imaging data of 12 medical dispute cases were collected. CT imaging diagnosis results and anatomy findings as well as differences between antemortem and postmortem CT diagnosis were compared. The advantages and disadvantages of CT routine tests of the cadavers in terms of the diagnosis of disease and damage were analyzed. Results The comparison between CT imaging diagnosis and anatomical findings showed that CT scans had advantages in the diagnosis of disease and damage with large differences in density changes, such as atelectasis, pneumonia, calcification, fracture and hemorrhage, etc. The comparison of CT diagnosis in antemortem and postmortem examination showed that the cadavers of medical dispute cases were well preserved and that postmortem CT scan was meaningful for the diagnosis of antemortem diseases. Conclusion Virtual anatomy technology has a relatively high application value in postmortem examination of medical dispute cases. It can provide effective information for the appraisers before the autopsy and can also provide a reference for cause of death analysis when the anatomy cannot be performed.

Objective: To observe the effect of Pinelliae Rhizoma Praeparatum Cum Alumine polysaccharides(PRPCAP)on airway mucus secretion in rats with allergic asthma, in order to study the material basis of the "macromolecule" component of the polysaccharides as the original medicinal materials. Method: The 60 SPF-grade Wistar rats were induced by intraperitoneal injection of chicken ovalbumin (OVA) and aluminum-magnesium adjuvant, except for the normal control group. The OVA solution was aerosolized to establish a rat model of allergic asthma. After successful modeling, the rats were randomly divided into 5 groups, namely allergic asthma model group, positive drug group (montalurast sodium,5 mg·kg^-1), high-dose PRPCAP group (400 mg·kg^-1), middle-dose PRPCAP group (200 mg·kg^-1) and low-dose PRPCAP group (100 mg·kg^-1). The contents of interleukin-4 (IL-4) and interferon-γ (IFN-γ) in serum and bronchoalveolar lavage fluid (BALF) supernatant were determined by enzyme-linked immunosorbent assay (ELISA), and the count of eosinophils (EOS) was detected by BALF sediment. The histopathological changes were observed by hematoxylin-eosin (HE) staining in lung tissue. The mRNA expression of mucin 5AC (MUC5AC) was detected by Real-time fluorescent quantitative polymerase chain reaction (Real-time PCR). Result: Compared with the normal control group, serum IL-4 level in the allergic asthma model group was significantly increased (P<0.01), IFN-γ level was significantly decreased (P<0.01), and EOS counts in BALF were significantly increased (P<0.01). Compared with the allergic asthma model group, the positive drug group, and high, middle, and low-dose PRPCAP groups could significantly reduce the serum IL-4 content (P<0.01), while high and middle-dose PRPCAP groups could significantly reduce the content of IL-4 in BALF (P<0.05, P<0.01), the middle-dose PRPCAP group could significantly increase the content of IFN-γ in serum (P<0.05), EOS counts in BALF were significantly lower in the positive drug group and all of PRPCAP groups (P<0.01). HE staining showed the pathological changes in the lung tissue of the allergic asthma model group and a mitigating effect in the positive drug group and all of PRPCAP groups. Compared with the normal control group, the expression of MUC5AC mRNA in the lung tissue of rats with allergic asthma was significantly increased (P<0.01). Compared with the model group of allergic asthma rats, the positive drug group and all of PRPCAP groups showed significant decrease in MUC5AC mRNA (P<0.01). Conclusion: The "macromolecule" component of polysaccharides in the Pinelliae Rhizoma Praeparatum Cum Alumine may be the material basis for the efficacy of eliminating dampness and eliminating phlegm.

Objective: To elucidate the possible role of human lysozyme-like protein 4 (LYZL4) in fertilization and characterize its enzymatic properties. METHODS: The localization of LYZL4 in human spermatozoa was investigated by immunofluorescence staining, the sources of LYZL4 on the sperm surface examined by RT-PCR, and the role of LYZL4 in fertilization assessed by the zona-free hamster egg penetration test. The recombinant plasmid pPIC9K-LYZL4 was constructed and its expression induced with methanol after transformed into competent Pichia pastoris GS115. The recombinant LYZL4 protein (rLYZL4) was purified from the fermentation supernatant and subsequently identified by Western blot. The hyaluronan binding ability of rLYZL4 was determined by ELISA and the muramidase activity, hyaluronidase activity, and free radical scavenging ability examined by spectrophotometric methods. RESULTS: Immunodetection with a specific antiserum localized LYZL4 on the acrosomal membrane of mature spermatozoa, which was exclusively secreted from the testis and epididymis as shown by RT-PCR. Immunoneutralization of LYZL4 significantly decreased the number of human spermatozoa bound to zona-free hamster eggs in a dose-dependent manner in vitro. The recombinant protein was expressed successfully by the P. pastoris strain GS115. Purified rLYZL4 exhibited a potent hyaluronan binding ability and a strong free radical scavenging ability but no muramidase or hyaluronidase activity. CONCLUSIONS LYZL4 secreted from the testis and epididymis is localized on the acrosomal membrane of mature spermatozoa and plays a role in sperm-egg binding as well as in binding hyaluronan and scavenging free radicals, which suggests that it might be a multi-functional molecule contributive to sperm protection and sperm-egg binding.

At present, there were few studies about the effects of cultivation measures on the quality and pharmacological activity of medicinal plants. To explore the hepetoprotective activity of Sedum sarmentosum aqueous extracts after different water treatments, S. sarmentosum were planted under five water treatments for 60 days, namely 15%-20% FC (field capacity, S1), 35%-40% FC (S2), 55%-60% FC (S3), 75%-80% FC(S4), and 95%-100% FC (S5) and CCl₄ drug-induced liver injury model in vitro was used. Cell viability, cell cycle, and cell apoptosis were individually detected by MTT, PI single staining, and Annexin-V FITC/PI double staining assays. Additionally, ALT, AST and antioxidant index in supernatant were determined by colorimetry. The results showed that, compared with the model group, S. sarmentosum aqueous extract could significantly improve the HepG2 cell viability. Among the five S. sarmentosum groups, the cell viability of S4 (75%-80% FC) treatment was the highest, and the cell apoptosis was the least. Meanwhile, the level of ALT, AST, and MDA in S4 was the lowest, but it achieved the highest level of SOD and GSH. Taken together, different water treatments had great influence on hepatoprotective effect of S. sarmentosum, and the soil moisture of the 75%-80% FC is beneficial to the hepetoprotective activity of S. sarmentosum.
