Objective : To estimate the prevalence and risk factors of suicide ideation,suicide planning and suicide attempts among middle school students and to provide reference for suicide intervention. Methods : The students of grade 7 to 12 in Ningbo were recruited through multi-stage random sampling method. A self-reported questionnaire survey was conducted to collect the information about suicide ideation,suicide planning and suicide attempts within 12 months. A multivariate logistic regression model was used to analyze the risk factors for the three aspects of suicide among middle school students. Results: A total of 10 729 questionnaires were sent out and 10 726 valid ones were collected,with a validity rate of 99.97%. The prevalence rates of suicide ideation,suicide planning and suicide attempts among middle school students during the last 12 months were 12.93%,4.54% and 5.06%,respectively. The results of multivariate logistic regression analysis indicated that females（OR：1.397-1.575,95%CI：1.178-1.927）,students of grade 7 to 9（OR：1.625-1.824,95%CI：1.323-2.082）,poor health condition（OR：1.160-2.131,95%CI：1.005-2.985）,loneliness（OR：1.574-4.423,95%CI：1.221-5.254 ）,desperation（OR：2.796-3.232,95%CI：2.400-3.990）,anxiety（OR：1.890-2.117,95%CI：1.503-2.496）,less than 8 hours a day of sleep（OR：1.152-1.263,95%CI：1.030-1.594）,smoking（OR：1.476-2.074,95%CI：1.055-3.072）,drinking（OR：1.479-1.863,95%CI：1.271-2.296）,fighting（OR：1.716-1.941,95%CI：1.330-2.422）and school bullying（OR：2.254-3.292,95%CI：1.342-5.277）were common risk factors for suicide ideation,suicide planning and suicide attempts;physical activity（OR：0.597-0.720,95%CI：0.474-0.923）was a common protective factor for suicide ideation,suicide planning and suicide attempts. Conclusion Females,lower grade,poor health condition,loneliness,desperation,anxiety,lack of sleep,smoking,drinking,fighting,school bullying and physical activity were influencing factors for suicidal behaviors.

OBJECTIVE： To investigate and analyze medication information labeling in package inserts of anticancer drugs， and to provide reference for clinical rational use. METHODS： The package inserts of anticancer drugs were collected from drug catalogues of 3 Third Grade Class A hospitals in Nanjin. Common problems of drug package inserts （whether the main contents arweree contradictory or not and whether the contents were fully expressed， etc.）， complete specific labeling items （detailed contents of “ADR” “contraindication” “precautions” and other items）， detailed intravenous injection dispensing guidance （solvent selection， precautions during dispensing， etc.）， package insert labeling difference of drugs with same general name and route of administration were evaluated according to Drug Package Inserts and Label Management Regulation，Regulations for Chemical Drugs and Biological Products for Treatment. RESULTS： A total of 157 package inserts for anticancer drugs were collected and divided into domestic drugs （80 pieces） and imported drugs （77 pieces） according to the source as well as also divided into oral preparation （44 pieces） and injection （113 pieces）. The common problems of package inserts for anticancer drugs contained contradictory main contents， incomplete description， Chinese character errors， missing items and simple description of drug interactions， etc. Compared with domestic or oral anticancer drugs， the labeling rate of each item in the import or injection anticancer drug package inserts was higher， but specific labeling items such as prevention and treatment of vomiting （＜20％） under “precautions” and interference of drugs on clinical tests （＜40％） were lower. The labeling rate of serious ADR after large dose or long-term use was all less than 41％ under the item of “drug overdose” （except for imported drugs）. The labeling rate of intravenous dispensing guidance of imported anticancer drug injection package inserts about preparations was higher than that of domestic ones. There were differences in labeling items as “precautions” （30/56，53.57％）， “pharmacological toxicology” （29/56，51.79％）， “contraindication” （26/56，46.43％） among 56 groups of drug package inserts with same general name and route of administration. CONCLUSIONS： The labeling items for drug package inserts of anticancer drugs need to be further standardized and improved. It is recommended that the relevant departments force pharmaceutical manufacturers to regularly supplement the deficiencies in the package inserts to improve the safety of drug use in clinic.

ObjectiveTo investigate the clinical efficacy of Niaoxue No.1 Prescription in treating Henoch-Schönlein purpura （HSP） nephritis with blood heat and stasis syndrome and its effect on urine erythrocyte， urine protein， blood neutrophils， and blood routine-derived indicators. MethodA multicenter， randomized controlled trial （RCT） was conducted involving 108 HSP nephritis patients from three hospitals. The patients were randomly divided into a control group （54 cases） and a treatment group （54 cases）. The treatment group received Niaoxue No.1 prescription once daily， while the control group was treated with captopril and ferulic acid tablets. Both groups underwent a 4-week course of treatment. The urine erythrocyte， urine microalbumin （mAlb）， urine sediment red blood cell count， traditional Chinese medicine （TCM） syndrome score， 24-hour urine protein， blood neutrophil count， neutrophil to lymphocyte ratio （NLR）， platelet to lymphocyte ratio （PLR）， lymphocyte to monocyte ratio （LMR）， D-dimer， and immunoglobulin A were detected. The recurrence rate of HSP nephritis was followed up for 6 months. ResultThe total effective rates were 88.9% （48/54） in the treatment group and 70.4% （38/54） in the control group， and the treatment group was superior to the control group （χ²=5.708， P<0.05）. Compared with the results before treatment， after 14 days of treatment， the TCM syndrome total score， urine erythrocyte， urine mAlb， and 24-hour urine protein in both groups significantly decreased （P<0.05，P<0.01）， and the improvement was more significant in the treatment group than the control group （P<0.05）. After 28 days of treatment， compared with the results before treatment， the TCM syndrome total score， urine erythrocyte， urine mAlb， urine sediment red blood cell count， D-dimer， and 24-hour urine protein in both groups significantly decreased （P<0.05，P<0.01）， with the treatment group showing a more significant reduction in urine mAlb than the control group （P<0.05）. On the 14^th and 28^th days of treatment， the neutrophil percentage and NLR were lower in the treatment group than in the control group （P<0.05）， while there was no statistically significant difference in PLR and LMR. The recurrence rate of nephritis in both groups showed no statistically significant difference after a 6-month follow-up. ConclusionNiaoxue No.1 Prescription in the treatment of HSP nephritis with blood heat and stasis syndrome can significantly improve clinical symptoms， shorten the course of the disease， and reduce urine erythrocyte， urine mAlb， 24-hour urine protein， blood neutrophils， and NLR， thereby effectively alleviating the inflammatory state and reducing kidney damage in children with HSP nephritis.

BACKGROUND: Long non-coding RNA colon cancer-associated transcript 1 (CCAT1) is involved in transforming multiple cancers into malignant cancer types. Previous studies underlining the mechanisms of the functions of CCAT1 primarily focused on its decoy for miRNAs (micro RNAs). However, the regulatory mechanism of CCAT1-protein interaction associated with tumor metastasis is still largely unknown. The present study aimed to identify proteome-wide CCAT1 partners and explored the CCAT1-protein interaction mediated tumor metastasis. METHODS: CCAT1-proteins complexes were purified and identified using RNA antisense purification coupled with the mass spectrometry (RAP-MS) method. The database for annotation, visualization, and integrated discovery and database for eukaryotic RNA binding proteins (EuRBPDB) websites were used to bioinformatic analyzing CCAT1 binding proteins. RNA pull-down and RNA immunoprecipitation were used to validate CCAT1-Vimentin interaction. Transwell assay was used to evaluate the migration and invasion abilities of HeLa cells. RESULTS: RAP-MS method worked well by culturing cells with nucleoside analog 4-thiouridine, and cross-linking was performed using 365 nm wavelength ultraviolet. There were 631 proteins identified, out of which about 60% were RNA binding proteins recorded by the EuRBPDB database. Vimentin was one of the CCAT1 binding proteins and participated in the tumor metastasis pathway. Knocked down vimetin ( VIM ) and rescued the downregulation by overexpressing CCAT1 demonstrated that CCAT1 could enhance tumor migration and invasion abilities by stabilizing Vimentin protein. CONCLUSION CCAT1 may bind with and stabilize Vimentin protein, thus enhancing cancer cell migration and invasion abilities.

Since December 2019, the corona virus disease 2019 (COVID-19) caused by the 2019 novel coronavirus (2019-nCoV) has been reported in Wuhan, Hubei Province. Almost 70% of patients susceptible to 2019-nCoV are over age of 50 years, with extremely large proportion of critical illness and death of the elderly patients. Meanwhile, the elderly patients are at high risk of osteoporotic fractures especially osteoporotic vertebral compression fractures (OVCF). During the prevention and control of COVID-19 epidemic, orthopedists are confronted with the following difficulties including how to screen and protect OVCF patients, how to accurately diagnose and assess the condition of OVCF patients with suspected or confirmed COVID-19, and how to develop reasonable treatment plans and comprehensive protective measures in emergency and outpatient clinics. In order to standardize the diagnosis and treatment of patients with OVCF diagnosed with COVID-19, the authors jointly develop this expert consensus. The consensus systematically recommends the standardized emergency and outpatient screening and confirmation procedures for OVCF patients with suspected or confirmed COVID-19 and protective measures for emergency and outpatient clinics. Moreover, the consensus describes the grading and classification of OVCF patients diagnosed with COVID-19 according to the severity of illness and recommends different treatment plans and corresponding protective measures based on the different types and epidemic prevention and control requirements.
