Objective To evaluate the efficacy and safety of intravascular lithotripsy(IVL)in the treatment of coronary artery calcification in patients with acute coronary syndrome(ACS)and chronic coronary syndrome(CCS).Methods In a retrospective study,patients with coronary artery calcified lesions who underwent IVL treatment at the Department of Cardiology,Second Affiliated Hospital of Xi'an Jiaotong University between February 2023 and June 2024 were enrolled.Among them,22 patients in ACS group and 25 patients in CCS group.The differences in baseline data,complication,clinical success rate and major cardiovascular adverse events(MACE)in patients followed one month after the procedure were compared between the two groups.Results In the ACS group,21 stent implantations were successful(95.5％success rate),while in the CCS group,25 cases were successful(100.0％success rate),showing no statistically significant difference between the two groups(P=0.468).There was one case of intraoperative IVL balloon rupture in the ACS group(1/22;4.5％),while in the CCS group,three cases were observed(3/25;12.0％).Additionally,one case in the ACS group(1/22;4.5％)with slow blood flow after IVL calcification modification.No instances of IVL-related vessel dissection or target vessel rupture occurred between the two groups,and there was no statistically significant difference in intraoperative complications(all P＞0.05).There was no significant difference in the MACE(9.1％vs.4.0％,P=0.593)between the two groups for follow up of one month.Conclusions The technique of IVL is a safe and effective treatment option for patients with ACS or CCS who have coronary artery calcification lesions.

OBJECTIVE: To understand the true perception and attitude of the healthcare workers(HCWs) on the workplace violence(WPV) in a secondary Grade A hospital.METHODS: A total of 27 HCWs in a secondary Grade A hospital were selected as study subjects using a typical sampling method. Semi-structured interviews were conducted to collect the information of their perception and attitude on the types and effects of WPV, as well as on the coping measures and the work stress. The characteristics of WPV in the hospital were analyzed. RESULTS: The interviewees believed that verbal abuse was the most common type of WPV received by HCWs. Nurses and female workers were the main victims of WPV. Horizontal violence among colleagues and sexual harassment should not be ignored. Common causes of violent incidents for patients and their family members against HCWs included the fees for treatment, doctor-patient communication, patients alcohol abuse and treatment outcomes not meeting patients′ expectation. About half of the interviewees said that WPV had serious impact on their mental health. The follow-up coping measures to violent incidents were mostly to reassurance to patients with unconditional apology from the HCWs. More than half of the interviewees considered that they had acceptable workload, while some interviewees considered their work to be stressful. The interviewees suggested that improving doctor-patient communication, hospital systems, and the professional knowledge of HCWs were the recommended means to prevents and control the WPV. CONCLUSION: The perception and attitude of HCWs on WPV in this hospital are relatively scattered. Considering the complex causes, the serious consequences, and difficult coping measures, the hospitals, HCWs and all sectors of society need to take comprehensive measures to prevent WPV towards HCWs.

OBJECTIVETo investigate the feasibility of interphase FISH in the routine clinicopathological practice and its values in the differential diagnosis of lymphomas.

METHODSA total of 74 fresh tissue samples clinically suspicious of lymphoma were investigated by FISH using three probes including IgH/bcl-2, IgH/CCND1 and API2/MALT1, corresponding the translocation t(14;18), t(11;14) and t(11;18) respectively. The results of FISH were analyzed and compared with the histopathologic diagnosis.

RESULTSHistological evaluation eventually confirmed that there were 62 cases of lymphoma and 12 cases of reactive lymphoid processes. The translocations were detected in 7 cases in 62 cases of lymphoma: 3 demonstrated t(14;18) including 2 cases of follicular lymphomas and 1 nodular sclerosing Hodgkin lymphoma. Four cases had t(11;14) including mantle cell lymphoma (2 cases), follicular lymphoma (1 case) and small cell lymphoma (1 case). A lymphoid hyperplasia case showed detectable t(14;18). All 25 cases of DLBCL showed no evidence of t(14;18). Amplification or loss of regional genes was seen more often in malignant than in the benign cases.

CONCLUSIONInterphase FISH offers useful ancillary technology that plays an important role in differential diagnosis and classification of lymphoma.
