This study aims to explore the impact on patient's liver and kidney function by different dosage of Kudiezi injection. This study retrospectively analyzed 15 228 patients' records from 18 nationwide general hospital information system (HIS). All patients were treated with Kudiezi injection, 1 956 patients that were given doses of > 40 mL, which is above the recommended dose, acted as the observation group. Fifty-five patients receiving the recommended dose of < 40 mL were the control group. Data about alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine (Cr) and blood urea nitrogen (BUN) were collected before and after using Kudiezi injection, changes after treatment were outcomes. Also recorded were: age, costs, length of hospitalization and the patients' condition on admission. Propensity score method was used to balance 71 confounding variables such as gender, age, mortality, and costs. There were no significant difference on the four indexes between the two groups. It is hard to conclude that the use of Kudiezi injection over the recommended dose could influence the four indexes of liver and kidney from this data analysis. More conclusive evidence should be collected by further prospective study.

OBJECTIVETo determine the adhering ability of Leptospira interrogans to extracellular matrix molecules (ECM) of host cells and its diversity.

METHODSThe infection models of L. interrogans serogroup Icterohaemorrhagiae serovar lai strain 56601 to J774A.1, L929 and Vero cells were established. Fontana silver impregnation method was applied to demonstrate the adhering effect of microbes to extracellular matrix (ECM) of the cells. ELISA methods were established to detect the adhering effects of L. interrogans to ECM molecules laminin (LN), fibronectin (FN), decorin (DEN) and collagen1, 2, 4 (COL1, 2, 4). A competitive inhibition test was performed to verify the results.

RESULTL. interrogans strain 56601 adhered the ECMs of L929, J774A.1 and Vero cells with its one or two sites. L. interrogans strain 56601 adhered all six ECM molecules; the adhering effects to COL1, LN, COL4 were relatively stronger. The adhering effects were markedly decreased after the microbes were pre-incubated with corresponding ECM molecules.

CONCLUSIONL. interrogans adheres to host cells through ECM molecules; LN, FN, DEN, COL1, COL2 and COL4 are the receptor molecules with different adhesion intensity.

OBJECTIVE To clarify out the network pharmacology mechanism of Polygala tenuifolia against Alzheimer disease(AD).METHODS Firstly,we collected the chemical constituents from Polyg-ala tenuifolia and key targets toward AD.Machine learning algorithms were applied to construct classifi-ers for predicting the effective constituents. Secondly, docking models were utilized for further evalua-tion.Finally,we built constituent-target,target-target network and target-biology pathway network.RE-SULTS 104 chemical constituents Polygala tenuifolia from were collected.Through prediction of blood-brain penetration and validation,36 chemical constituents were selected among 100 chemical constitu-ents,their action targets mainly focused on AChE,COX-2,TNF-α,insulin-degrading enzyme and APP. Their main structure types include Polygala saponins, Polygala glycosides, Polygala shrubby ketones, polygala xanthones and sterols,which acted on AchE,APP,M-TAU,GSK3β and 5HT1A with high fre-quency.Gene-Ontology and KEGG enrichment analysis showed that the main pathways of these con-stituents involve in neurotransmitter release,synaptic conduction and synaptic plasticity,apoptosis reg-ulation,phosphorylation pathway,Ca2+signaling pathway,and so on.CONCLUSION This study uncov-ered a network mechanism of Polygala tenuifolia against Alzheimer disease,which may provide impor-tant information for the further study and new drug development.

Influenza caused by influenza virus,seriously threaten human life and health.Drug treatment is one of the effective measurement. However, there are only two classes of drugs, one class is M2 blockers and another is neuraminidase (NA)inhibitors. The recent antiviral surveillance studies reported a global significant increase in M2 blocker resistance among influenza viruses, and the resistant virus strains against NA inhibitor are also reported in clinical treatment.Therefore thediscovery of new medicines with low resistance has become very urgent.As all known,traditional medicines with multi-target features and network mechanism often possess low resistance. Compound Yizhihao, which consists of radix isatidis,folium isatidis,Artemisia rupestris,is one of the famous traditional medicine for influenza treatment in China, however its mechanism of action against influenza is unclear. In this study, the multiple targets related with influenza disease and the known chemical constituents from Compound Yizhihao were collected, and multi-target QSAR (mt-QSAR) classification models were developed by Na?ve Bayesian algorithm and verified by various datasets. Then the classification models were applied to predict the effective constituents and their drug targets.Finally,the constituent-target-pathway network was constructed,which revealed the effective constituents and their network mechanism in Compound Yizhihao. This study will lay important basis for the clinical uses for influenza treatment and for the further research and development of the effective constituents.

Objective To investigate the value of the imaging findings of soft tissue abnormality in the differential diagnosis between osteomyelitis and malignant bone tumor.Methods The CT and MRI findings of soft tissue changes in 57 cases of osteomyelitis and 70 cases of malignant bone tumor were retrospectively defined,observed,recorded and statistically analyzed.Results In 57 cases of osteomyelitis, 54 cases were examined with CT,and soft tissue swelling was presented in 52 cases (degree Ⅰin 19 cases, degreeⅡin 16 cases,degree Ⅲin 17 cases).Abscess-like cysts in soft tissue occurred in 6 cases,masses in 5,air in 1,fat-fluid level in 1 and sinus tract in 1.Among 14 cases examined with MR imaging,soft tissue swelling was presented in all cases (degreeⅠin 2 cases,degree Ⅱin 6 cases and degree Ⅲin 6 cases). Abscess-like cysts appeared in 3 cases and showed high signal in diffusion weighted imaging, mass in Ⅰand fat-fluid level in 1.Among 54 cases examined with CT in 70 cases of malignant bone tumor, soft tissue swelling was presented in 44 cases (degreeⅠin 29 cases,degreeⅡin 12 cases,degreeⅢin 3 cases).Soft tissue masses appeared in 49 cases,bone shell and shell-like calcification in 16 cases and neoplastic bone and neoplastic calcified cartilage within soft tissue mass in 25 cases.Among 49 cases examined with MR imaging,soft tissue swelling was presented in 46 cases (degree Ⅰin 21 cases,degreeⅡin 17 cases and degree Ⅲin 8 cases),and soft tissue masses appeared in 43 cases.The degree of soft tissue swelling and the occurrence of abscess-like cyst,mass,bone shell or shell-liked calcification in the rim of mass,neoplastic bone or neoplastic calcified cartilage in masses showed significant difference(P

To investigate whether lithium carbonate, propranolol or chloroquine aggravate psoriasis through influencing cytokines of the psoriatic cytokine network, HaCaT keratinocytes were stimulated with TNF-a after treatment with these drugs. Protein secretion of a set of multiple different cytokines and growth factors in culture supernatants were measured by using a cytokine antibody array technology. Expression of IL-8 and IL-6 mRNA was determined by real-time PCR. In culture supernatants of TNF-alpha-stimulated HaCaT cells, production of IL-6 and TNF-alpha could be enhanced by lithium carbonate; production of IL-6 and a panel of cytokines and growth factors could be enhanced by propranolol hydrochloride; and IL-6 was up-regulated by chloroquine diphosphate as well. Real-time PCR analysis showed a significantly dose-dependent increase of IL-8 and IL-6 mRNA expression in HaCaT cells stimulated with TNF-a as compared to cells without TNF-alpha-stimulation, the mRNA expression of IL-8 was higher than that of IL-6 with the same concentration of TNF-alpha (P < 0.01). Compared with HaCaT cells cultured with medium alone, propranolol hydrochloride at the concentration of 1 x 10(-6) mol x L(-1) could stimulate HaCaT cells to express higher level of IL-6 mRNA (P < 0.05). The drugs investigated show a modulatory effect on certain cytokines and growth factors which are able to modulate inflammatory type of immune reaction present in psoriatic lesions.
