OBJECTIVE To compare the efficacy and safety of evolocumab and probucol in patients with ultra-high-risk atherosclerotic cardiovascular disease （ASCVD） following percutaneous coronary intervention （PCI）. METHODS A retrospective analysis was conducted on 156 ultra-high-risk ASCVD patients who underwent PCI in our institution between January 1， 2023 and December 31， 2024. According to the lipid-lowering regimen， the patients were categorized into evolocumab group （ n ＝86） and probucol group （ n ＝70）. Changes in lipid parameters [total cholesterol （TC）， low-density lipoprot ein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， triglycerides， lipoprotein （a）， and lipid goal achievement rate ] ， inflammatory markers [interleukin-6 （IL-6） and C-reactive protein （CRP） ] ， and cardiac function indices （left ventricular ejection fraction， left ventricular end-systolic diameter， left ventricular end-diastolic diameter， and N-terminal pro-B-type natriuretic peptide） were compared between two groups at baseline and after 6 months of treatment. The incidence of adverse clinical events during treatment， including acute myocardial infarction， in-stent restenosis， acute heart failure， cerebral hemorrhage， and stroke， was also evaluated. RESULTS No statistically significant differences were observed between the two groups at baseline （ P ＞0.05）. After 6 months of treatment， both groups demonstrated significant improvements in lipid profiles （except HDL-C） and inflammatory markers compared to those at baseline （ P ＜0.05）. The evolocumab group exhibited greater reductions in TC， LDL-C， IL-6， and CRP， along with a higher lipid target achievement rate， compared with the probucol group （ P ＜0.05）. There were no statistically significant differences in the cardiac function-related indicators before and after treatment between the two groups， nor in the incidence of adverse events during the treatment （ P ＞0.05）. CONCLUSIONS For ultra-high-risk ASCVD patients after PCI， both of the above treatment options are associated with improvements in blood lipid and inflammatory response， with good safety during short-term follow-up. Evolocumab shows superior efficacy in TC， LDL-C and inflammatory markers reduction and lipid target achievement， compared to probucol.

Background::Histological healing is closely associated with improved long-term clinical outcomes and lowered relapses in patients with ulcerative colitis (UC). Here, we developed a novel diagnostic criterion for assessing histological healing in UC patients.Methods::We conducted a retrospective cohort study in UC patients, whose treatment was iteratively optimized to achieve mucosal healing at Shanghai Tenth People’s Hospital of Tongji University from January 2017 to May 2022. We identified an inflammatory cell enumeration index (ICEI) for assessing histological healing based on the proportions of eosinophils, CD177 + neutrophils, and CD40L + T cells in the colonic lamina propria under high power field (HPF), and the outcomes (risks of symptomatic relapses) of achieving histological remission vs. persistent histological inflammation using Kaplan-Meier curves. Intrareader reliability and inter-reader reliability were evaluated by each reader. The relationships to the changes in the Nancy index and the Geboes score were also assessed for responsiveness. The ICEI was further validated in a new cohort of UC patients from other nine university hospitals. Results::We developed an ICEI for clinical diagnosis of histological healing, i.e., Y = 1.701X 1 + 0.758X 2 + 1.347X 3 - 7.745 (X 1, X 2, and X 3 represent the proportions of CD177 + neutrophils, eosinophils, and CD40L + T cells, respectively, in the colonic lamina propria under HPF). The receiver operating characteristics curve (ROC) analysis revealed that Y <-0.391 was the cutoff value for the diagnosis of histological healing and that an area under the curve (AUC) was 0.942 (95% confidence interval [CI]: 0.905-0.979) with a sensitivity of 92.5% and a specificity of 83.6% ( P <0.001). The intraclass correlation coefficient (ICC) for the intrareader reliability was 0.855 (95% CI: 0.781-0.909), and ICEI had good inter-reader reliability of 0.832 (95% CI: 0.748-0.894). During an 18-month follow-up, patients with histological healing had a substantially better outcome compared with those with unachieved histological healing ( P <0.001) using ICEI. During a 12-month follow-up from other nine hospitals, patients with histological healing also had a lower risk of relapse than patients with unachieved histological healing. Conclusions::ICEI can be used to predict histological healing and identify patients with a risk of relapse 12 months and 18 months after clinical therapy. Therefore, ICEI provides a promising, simplified approach to monitor histological healing and to predict the prognosis of UC.Registration::Chinese Clinical Trial Registry, No. ChiCTR2300077792.

To summarize the nursing care of a case with perioperative sudden electrical storm of heart valvular disease treated with stellate ganglion block.Nursing points are as follows:to avoid triggering factors before surgery,with early identification of electrical storms;to implement emergency management of electric storm and improve rescue quality;to improve the operation preparation,intraoperative cooperation and observation;to conduct rapid and accurate assessment and pre-control of postoperative complications;to formulate rehabilitation strategies to promote postoperative rehabilitation;to strengthen psychological intervention to ensure emotional stability.The patient was transferred to the department of cardiac surgery from the department of cardiology to install a permanent cardiac resynchronization pacemaker in 6 days after surgery,and discharged successfully 10 days after surgery.The results were good at 14 d and 28 d post-discharge follow-up.

The detection of peripheral pulmonary lesions has increased gradually with the popularity of CT. Rapid and accurate diagnosis, and individualized treatment are two aspects we need to pay great attention to. These situations also raise higher request for the technique in diagnosis and treatment. At present, the commonly used transthoracic methods can increase the risk of complications such as pneumothorax and bleeding. The newly bronchoscopic approaches for diagnosis and treatment make less injury via natural lumen and have been applied widely in clinics. This review will introduce the worth expecting progress in bronchoscopic diagnosis and treatment for peripheral pulmonary lesions.

Objective:To analyze the prevention and treatment of Kaschin-Beck disease in Fu County, Shaanxi Province, so as to provide basis for consolidating the results of Kaschin-Beck disease prevention and control and the treatment of patients with Kaschin-Beck disease.Methods:The epidemiological investigation of data and clinical data Kaschin-Beck disease from 1954 to 2022 were collected from the Fu County Institute for Endemic Disease Prevention and Control and People's Hospital of Fu County in Shaanxi Province, respectively. The retrospective study was used to investigate the prevention and control of Kaschin-Beck disease in Fu County through the adoption of comprehensive measures such as relocation, grain exchange, water improvement, conversion of farmland to forest and so on.Results:In 1954, there were 6 endemic townships and 127 endemic villages of Kaschin-Beck disease in Fu County, with a total population of 78 781. A total of 16 327 patients with Kaschin-Beck disease were detected by X-ray examination, with a detection rate of 20.72%, including 5 434 patients without clinical symptoms. There were 5 850 patients with clinical grade Ⅰ, 3 725 patients with clinical grade Ⅱ and 1 318 patients with clinical grade Ⅲ. In 1975, the first general survey of Kaschin-Beck disease was conducted in the whole county, with a total population of 101 341. A total of 9 575 patients with Kaschin-Beck disease were detected by X-ray examination, with a detection rate of 9.45%, including 3 247 cases without clinical symptoms. Among the patients with symptoms, there were 3 704 cases of clinical grade Ⅰ, 2 006 cases of clinical grade Ⅱ and 618 cases of clinical grade Ⅲ. The patients with Kaschin-Beck disease were mainly local residents, accounting for 93.92% (8 993/9 575). In 1997, 27 320 students aged 7 to 16 years in 342 schools of 15 townships were examined and found that there were 169 cases without clinical symptoms with X-ray changes, only 2 cases with clinical grade Ⅰ, and the detection rate decreased to 0.63%. In 1997, Fu County began to encourage relocation and grain exchange to prevent Kaschin-Beck disease. The relocation targets were mainly the seriously ill villages with new cases among children and poor living conditions. By 1999, a total of 100 households and 469 people were relocated, and by 2020, 1 569 households and 5 334 people were relocated. In 1997 and 1998, measures were taken to improve water quality in 43 natural villages in 6 townships, with 1 591 households and 7 375 people benefiting. In 2010, a general survey of Kaschin-Beck disease was conducted in 15 townships of Fu County, with a total population of 135 858, and 3 424 patients with Kaschin-Beck disease were detected by X-ray examination, with a detection rate of 2.52%. There were 2 885 cases with clinical symptoms, including 1 584 cases with clinical grade Ⅰ, 1 024 cases with clinical grade Ⅱ and 277 cases with clinical grade Ⅲ. Among them, 32 561 minors under 16 years old were examined, and 49 patients with Kaschin-Beck disease were detected by X-ray examination, with a detection rate of 0.15%, and all of them were clinical gradeⅠ patients. In 2014, a total of 73 600 people were surveyed in 170 endemic villages of Fu county, and 2 885 patients with Kaschin-Beck disease were detected by X-ray examination, with a detection rate of 3.92%. Compared with 2010, the number of patients with Kaschin-Beck disease increased zero, and there were no underage patients under the age of 16 for 4 consecutive years. By the end of 2016, 666.67 hm 2 of farmland had been converted to forest in Fu County, involving 9 townships (including communities), 33 administrative villages and 1 993 households. In 2018, another general survey of Kaschin-Beck disease was conducted in Fu County, with a total population of 157 362. A total of 2 308 patients were detected by X-ray examination, with a detection rate of 1.47%. Among them, there were 1 270 cases of clinical grade Ⅰ, 870 cases of clinical grade Ⅱ and 168 cases of clinical grade Ⅲ, and there were no patients with Kaschin-Beck disease under 16 years old in the county for 8 consecutive years (2011-2018). In the same year, 22 cases of Kaschin-Beck disease joint replacement were completed in Fu County, and by January 2022, about 60 cases had completed joint replacement. Conclusion:The prevention and control of Kaschin-Beck disease in Fu County has achieved remarkable results through comprehensive measures such as relocation, grain exchange, water improvement and conversion of farmland to forest.

Objective:Currently,patients with pre-exsiting donor-specific antibody(DSA)are prone to antibody-mediated rejection(AMR)after surgery and are at a relatively high risk of postoperative complications and graft failure.The risk of postoperative complications and graft failure is relatively high.This study aims to discuss the clinical outcome of DSA-positive kidney transplantation and analyze the role and safety of preoperative pretreatment in DSA-positive kidney transplantation,providing single-center treatment experience for DSA-positive kidney transplantation. Methods:We retrospectively analyzed the clinical data of 15 DSA-positive kidney transplants in the Department of Renal Transplantation of First Affiliated Hospital of Zhengzhou University from August 2017 to July 2022.Eight cases were organ donation after citizen's death(DCD)kidney transplant recipients,of which 3 cases in the early stage were not treated with preoperative desensitisation therapy(DCD untreated group,n=3),and 5 recipients were treated with preoperative rituximab desensitisation(DCD preprocessing group,n=5).The remaining 7 cases were living related donors recipients(LRD)who received preoperative desensitisation treatment with rituximab and plasma exchange(LRD preprocessing group,n=7).We observed and recorded the incidence of complications with changes in renal function and DSA levels in the recipients and the survival of the recipients and transplanted kidneys at 1,3 and 5 years,and to compare the differences in recovery and postoperative complications between 3 groups. Results:All 15 recipients were positive for preoperative panel reactive antibody(PRA)and DSA and were treated with methylprednisolone+rabbit anti-human thymocyte immunoglobulin induction before kidney transplantation.DCD untreated group all suffered from DSA level rebound,delayed renal graft function(DGF)and rejection reaction after surgery.After the combined treatment,DSA level was reduced and the graft renal function returned to normal.The DCD preprocessing group were all without antibody rebound,1 recipient developed DGF and the renal function returned to normal after plasmapheresis,and the remaining 4 recipients recovered their renal function to normal within 2 weeks after the operation.In the LRD preprocessing group,2 cases had antibody rebound and 1 case had rejection,but all of them recovered to normal after treatment,and DSA was maintained at a low level or even disappeared.The incidence of DGF and rejection in the DCD untreated group were significantly higher than that in the DCD preprocessing group and the LRD preprocessing group;and there were no significant difference in the incidence of postoperative haematuria,proteinuria,bacterial and fungal infections,and BK virus infection between the 3 groups(all P>0.05).A total of 11 of the 15 recipients were followed up for more than 1 year,6 for more than 3 years,and 1 for more than 5 years,and the survival rates of both the recipients and the transplanted kidneys were 100%. Conclusion:Effective preoperative pretreatment with desensitization therapy can effectively prevent antibody rebound in DSA-positive kidney transplantation and reduce perioperative complications.

Objective To retrospectively analyze the injury characteristics of victims and treatment strategies in the explosion accident on the 17th May 2018 in Xixia county (Xixia "May 17th" explosion accident). Methods Based on the practice featured in pre-hospital emergency of Henan province and Nanyang city Emergency Center in the explosion accident, a retrospective analysis for the Level Three medical rescue was conducted, where a total of thirteen survived victims in Xixia "May 17" explosion accident were studied retrospectively. The data included the gender, age, burned extent and depth of the patients, burns complicated by trauma, complication of burn, respiratory function maintenance, resuscitation during shock stage, skin grafting with excision and scab. Furthermore, the data of organ function and the effect of the 90-day comprehensive treatment for the burned victims wereanalyzed. Results completion the Level Three treatment on time, which was depended on the leading role played by the regional trauma centers was the main rescuing mode of the work in Xixia county, where the primary and secondary treatments were the key parts. The three-level treatment model includes: the local hospital acts as a level-one emergency medical institution, county hospitals function as secondary emergency medical institutions, and other higher medical institutions are the tertiary first aid medical institutions. The pre-hospital and in-hospital emergency procedures were initiated immediately after the large-scale explosive burn being identified, the key to the successfully rescue was to set up a comprehensive treatment team for burns and trauma. Rescue team should involve burn department and other related departments, including the departments of emergency, general surgery, orthopedic, thoracic surgery, neurosurgery, plastic surgery, intensive care unit, blood transfusion unit, anesthesiology, and interventional radiology, etc. All the thirteen burned patients were male, with inhalation injury, blast injury, hemopneumothorax, brain injury, bone fractures, and etc. Eight of them (61.54%) had multiple organ dysfunction syndrome (MODS). MODS mainly involved respiratory, circulatory, liver, gastrointestinal tract, kidney and coagulation function. With the multi-discipline treatment, the wound of 6 severely-burned patients started healing and can be discharged after keeping the patency of airway, applying resuscitation fluid and comprehensive treatments such as debridement and dressing change. Among 7 patients with extensive deep burns, one case with skull-based fracture, open craniocerebral, extensive intracranial hemorrhage and hemopneumothorax, died 9 hours later. Another case died within 24 hours after injury due to obvious exudation on the site of early incision and relaxation of wound. The escharotomy, micro-dermis and allograft skin transplantation were carried out for five cases with extensive deep burns from the 4th day after the recovery of shock. One week later, the second stage of microsphere skin transplantation was performed. But all died of sepsis or fungal infection. Conclusions MODS and infection often occur during the course especially for patients with extensive and deep burns due to the great explosion in Xixia county, most of whom were accompanied with MODS and infection. Therefore, assembling multi-discipline team for treating the group of explosively-burned patients can increase the survival rate and reduce the possibility of disability.

Objective To investigate the clinical significance of serum and urinary levels of neutrophil gelatinase-associated lipocalin (NGAL ) for evaluating changes of residual renal function after living donor kidney resection under different operation model in young versus elderly patients. Methods The clinical data of renal transplants were retrospectively analyzed by successfully using 66 living-related donors at the First Affiliated Hospital of Zhengzhou University from September 2016 to October 2017. According to the operation model and age ,renal donors were divided into 4 groups :group A (young/open) ,group B (young/laparoscopic) ,group C (aged/open) ,and group D (aged/laparoscopic).Blood and urinary NGAL and serum levels of creatinine ,cystatin C ,and other indices of renal function were assayed and collected before and at 1 ,3 ,7 days after operation. Results Both blood NGAL levels and urinary NGAL levels showed no statistically significant difference (all P>0.05) among four groups both before and after operation ,except that urinary NGAL was higher in group C (aged/open) than other groups ,at 1 day after operation ,(P = 0.03).The post-vs.pre-operation level dynamic changes of renal function were four or three times higher in urine or serum NGAL level than in serum creatinine or cystatin C level at 1 day after operation ,which showed an important role for predicting an early residual renal damage and relative treatment. Conclusions NGAL can be used as indices in evaluating changes of residual renal function after living donor kidney resection ,especially in the elderly receiving open kidney resection.

Objective To study the inhibitory effect of curcumin on the proliferation,migration and invasion of non-small cell lung cancer cell A549,and to discuss further if it is closely related to the expression of c-Jun N-terminal kinase (JNK) and relative protein p38.Methods A549 cells were cultured by conventional method,and then treated with different concentration of curcumin (10,20,40,80 μmol · L-1).The proliferation,migration and invasion of A549 cells were measured by real-time cellular analysis (RTCA).The expression levels of JNK,p-JNK,p38 and P-p38 were detected by real-time PCR and Western blotting.Results Curcumin showed an antiproliferation effect against A549 cells with IC50 =40 μmol · L-1,and curcumin exhibited obviously inhibitory effect on the migration and invasion of A549 cells.Additionally,compared with control group,curcumin suppressed the expression of JNK and p38 at the gene level,and significantly inhibited the expression of JNK,P-JNK,p38 and p38 (P＜0.05) at the protein level.Conclusion These results demonstrated that curcumin can inhibit the proliferation,migration and invasion of A549 cells via reducing the level of JNK,p38 phosphorylation,and blocking JNK signal transduction pathway.

Objective To investigate whether the amount of blood transfusion affects the lengths of stay (LOS),costs,and outcomes of hospital patients or not,and to prepare for the execution of patient blood management.Methods The data of hospital patients,who had been administrated with blood in our hospital during 2016,were collected.And the influence of blood transfusion volume on LOS,costs and outcomes of patients was analyzed retrospectively.Results LOS,costs and outcomes of patients vary significantly with the amount of blood transfusion (P＜0.01).There were positive correlations between the total amount of blood transfusion and LOS,costs,and outcomes of patients.The Spearman correlation coefficient was 0.317,0.497,0.290,respectively (P＜0.01).Plasma preparation transfusion volume has a great influence on LOS,costs,and outcomes than red blood cell (P＜0.05).The transfusion volume of death patients was significantly higher than that of the survival (P＜0.01).In particular,the amount of transfused plasma and precipitation was distinctly higher than that in death patients(P＜0.01).Conclusion Blood transfusion volume affects LOS,costs and outcomes of hospital patients.The administration of plasma preparations should deserve more attention.
