ObjectiveTo analyze and sum up treatment of paraquat intoxication. MethodsWe retrospectively analyzed the clinical data of 8 cases of paraquat intoxication. ResultOf the total number,2 cases abandoned treament, 1 case died,5 cases survived,of survival rate is 62. 5%. ConclusionWe take measures as early as possible, such as gastrolavaging completely, stomach intestine adsorbing, catharsis, continious blood purification and apply a large dose of xuebijing and hormone, thus can improve the survival rate of paraquat intoxication.

Objective:To test the validity and reliability of the Chinese version of the Br?set Violence Check-list (BVC-C).Methods:With the authorizing permission by the author,the BVC was translated into Chinese and a-dapted,and five psychiatry experts who had worked more than 20 years were invited (3 clinical doctors and 2 nur-ses)to evaluate the content validity of the scale as the content validity index.Totally 556 inpatients who met the di-agnosis criteria for mental disorders according to the International Statistical Classification of Diseases and Related Health Problems,Tenth Revision (ICD-10)were totally selected to proceed the formal testing.The BVC scale was used to evaluate inpatients every 8 hours,the Modified Overt Aggression Scale (MOAS)was used to test concurrent validity;the results of the real attacking incidents were used to test the criterion validity;the internal consistency re-liability of the scale was tested by Cronbach αcoefficient.Results:The content validity index of the scale was0.93.In addition to the own attack subscale,the MOAS total scores and the other 3 subscales scores were positively correlated with the BVC total scores and each item score (r =0.11 -0.69,P <0.01).The best criterion validity was 8 hours through analyzed,the AUC was 0.98.When the cut-off was 2,the sensitivity and specificity were 78.9% and 95.1% respectively.The Cronbach αcoefficient was 0.76 and the item total correlations were 0.47 -0.80 (P <0.01).Conclusion:It suggests that the BVC-C has good validity and reliability,which could be used as an effective prediction tool for psychiatric violence risk assessment.

Inflammation is involved in the development of various acute and chronic diseases in the body. Sustained inflammatory responses are key driving factors for diseases such as cancer， neurodegenerative diseases， cardiovascular diseases， metabolic syndrome， inflammatory bowel disease， and arthritis. Therefore， finding anti-inflammatory drugs is crucial for the prevention and treatment of various diseases. In recent years， there has been increasing attention to finding natural drugs with minimal toxic side effects. Lonicerae Japonicae Flos and Lonicerae Flos， as traditional Chinese medicines potent in clearing heat and removing toxins， have strong biological activity and multiple pharmacological effects. They are widely distributed in the plant world and have significant medicinal value. With the continuous advancement of the research on Lonicerae Japonicae Flos and Lonicerae Flos， they have been widely used in the medical field and possess great development potential. Currently， research mainly focuses on the anti-inflammatory mechanisms of Lonicerae Japonicae Flos and Lonicerae Flos， while systematic summaries of their anti-inflammatory active ingredients are rare. Therefore， this paper focuses on the differential analysis of the anti-inflammatory active components of Lonicerae Japonicae Flos and Lonicerae Flos. In addition， it reviewed the possible mechanisms by which extracts and active ingredients of Lonicerae Japonicae Flos and Lonicerae Flos may exert anti-inflammatory effects through various pathways， such as influencing the release of cellular inflammatory factors， regulating inflammatory signaling pathways such as nuclear factor-κB （NF-κB）， mitogen-activated protein kinase （MAPK）， signal transducer and activator of transcription 3 （STAT3）， MAPK/extracellular signal-regulated kinase （ERK）/c-Jun N-terminal kinase （JNK）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/NF-κB， and Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathways， increasing antioxidant stress capacity， enhancing immune defense capabilities， and improving intestinal microbiota， aiming to provide a theoretical basis for the rational clinical application of Lonicerae Japonicae Flos and Lonicerae Flos.

OBJECTIVETo evaluate the photodynamic therapy (PDT) against multi-antibiotic-resistant Staphylococcus aureus (S. aureus) and Staphylococcus epidermidis (S.epidermidis) obtained from patients with chronic rhinosinusitis (CRS).

METHODSForty-five CRS patients who had been given medical treatment but still needed endoscopic surgery were included in this study. The mucus from middle meatus was collected from these patients during surgery, followed by separation of S. aureus and S. epidermidis and drug sensitive test. The strains which could form biofilm were selected. Light emitting diode (LED) array with a major wavelength of (633±10) nm was used as light source and 5-Aminolevulinic acid (ALA) was used as photosensitizer in this PDT experiment. The safe range of LED dose and ALA concentration which were not toxic to bacteria by themselves were confirmed, and then did PDT experiment on S. aureus and S. epidermidis. The data of bacterial colony forming unit were transformed to lgCFU before statistical analysis.The Graph Pad Prism 5 software was used to analyzed the data.

RESULTSThirteen S. aureus and 16 S. epidermidis were included in this experiment(from 45 patients), all of them were multi-antibiotic-resistant bacteria, and four of S. aureus and five of S. epidermidis could form biofilm in each group. In planktonic S. aureus experiment, the mean lgCFU was 8.32±0.31 in control group whereas the experiment group was 6.47±0.67 (t=9.01, P<0.01), and in planktonic S. epidermidis experiment the final data was 8.34±0.20 (control group) and 6.97±0.59 (experiment group) (t=8.84, P<0.01). In biofilm S. aureus experiment, the mean lgCFU was 8.68±0.05 (control group), 6.90±0.96(experiment group) (t=3.68, P<0.05); and in biofilm S. epidermidis experiment the data was 8.67±0.05 (control group), 7.29±0.61 (experiment group, t=5.07, P<0.01).

CONCLUSIONOur results demonstrated that ALA-mediated PDT on multi-antibiotic-resistant S. aureus and S. epidermidis from CRS patients was effective in vitro. Additional work defining if the PDT treatment would damage the nasal mucosa and further checking the effectiveness of PDT in vivo is still needed.
