Objective To assess the clinical predictability of waist-to-hip ratio (WHR) among female civil servants who had experienced risk factors of cardiovascular disease. Methods Data was gathered from 4153 female civil servants aged 21-91 y working at universities who were enrolled in health screening centre at the Second Hospital Attached to Hebei Medical University, in 2006. WHR quartiles were determined as: <0.80, 0.80-<0.84, 0.84-<0.90 and ≥0.90. Subjects were placed into high-risk categories for cardiovascular disease on the basis of national health reference on range norms of protocol including hypertension, diabetes mellitus and dyslipidemia. Results Participants had an increased likelihood of hypertension (systolic blood pressure) , dyslipidemia (elevated triacylglycerol and descending HDL-C) and diabetes mellitus at WHR≥0.84. All aforementioned variables had a significant odds ratio at WHR ≥0.84. This trend was further persisted after adjustment had been made on smoking, age, and BMI. Descended HDL-C was observed at the 0.80≤WHR<0.84 when compared with WHR< 0.80. Conclusion These data indicated an upward shift in the critical threshold for WHR to ≥0.84. Above which point, there was an elevation of risk factors on cardiovascular diseases among all the female civil servants. The trend persisted regardless of smoking, BMI

ObjectiveTo investigate the difference in protein expression between hepatocellular carcinoma (HCC) patients with recurrence and those with good prognosis, the differential expression and regulatory mechanism of miR-152-3p target proteins, and the role of miR-152-3p in the recurrence of HCC. MethodsTMT-labeled proteomic sequencing and RT-PCR were used to measure the expression of proteins and the expression of miR-152-3p in the HCC tissue of six patients with recurrence at 2 years after HCC resection and six patients with good prognosis at 5 years. Six databases were used to analyze the target genes of miR-152-3p, and Gene Ontology, DAVID, and REACTOME databases were used to perform target gene screening, enrichment annotation, and signal transduction pathway enrichment analysis. Gene mutation frequency and survival curve analysis were performed for the target genes of miR-152-3p to verify the role of miR-152-3p target genes in patients with HCC recurrence. The independent samples t-test was used for comparison of continuous data between two groups, and a Kaplan-Meier analysis was performed to investigate the survival rates of liver-related genes. ResultsCompared with the patients with HCC recurrence, the patients with good prognosis after HCC resection had a significantly higher transcriptional expression level of miR-152-3p in HCC tissue (P＜0.05). The results of protein sequencing showed that there were 365 differentially expressed proteins in HCC tissue between the patients with good prognosis and the patients with recurrence, and the analysis of HCC recurrence databases showed that 17 proteins were regulated by miR-152-3p. Further analysis of the signaling pathways showed that the function of the 17 target genes regulated by miR-152-3p was enriched in the translation and regulation of mitochondria and ribosome, and multiple enrichment revealed that six target genes were closely associated with mitochondrial respiratory chain complex, i.e., AKAP1, FOXRED1, MRPL28, MRPL50, SHC1, and STAU1. Gene mutation frequency and survival curve analysis showed that the loss or weakening of the function of mitochondrial respiratory chain-related target proteins seriously affected the prognosis and survival rate of patients. ConclusionThere is a significant difference in the expression of miR-152-3p in HCC tissue between patients with good prognosis and those with recurrence after HCC resection, and miR-152-3p may lead to the recurrence of HCC by regulating the target genes AKAP1, FOXRED1, MRPL28, MRPL50, SHC1, and STAU1, acting on the mitochondrial respiratory chain, and affecting the oxidative respiratory function of cells.

Objective To study the efficacy and safety of different dual antiplatelet therapy(DAPT)in patients with acute myocardial infarction(AMI)undergoing percutaneous coronary intervention(PCI)treatment.Methods AMI patients receiving PCI treatment were randomly divided into treatment group and control group.The treatment group was given clopidogrel(50 mg,bid)combined with ticagrelor(90 mg,bid)after PCI,while the control group was given aspirin(100 mg,qd)combined with clopidogrel(75 mg,qd)after PCI.The treatment course for both groups was 6 months.Platelet activation and endothelial function-related indicators were compared between the two groups,and major adverse cardiovascular events(MACE)and adverse drug reactions were followed up during the treatment period.Results During the trial,5 cases dropped out,and finally,98 cases and 97 cases were included in the treatment group and control group,respectively.After treatment,the incidence of stent restenosis in the treatment group and control group were 2.04％(2 cases/98 cases)and 9.27％(9 cases/97 cases),respectively;the incidence of MACE were 4.08％(4 cases/98 cases)and 13.40％(13 cases/97 cases),respectively,with significant differences between the two groups(P＜0.05).After treatment,the inhibition of platelet aggregation(IPA)in the treatment group and control group were(54.97±6.43)％and(52.38±6.12)％,respectively;the serum nitric oxide(NO)levels were(64.29±8.12)and(59.61±8.45)μmol·L-1,respectively;the prostacyclin(PGI2)levels were(42.15±3.94)and(38.46±3.71)ng·L-1,respectively;the maximum platelet aggregation rate(MPAR)were(31.65±3.86)％and(32.97±4.25)％,respectively;the platelet count(PC)were(169.84±36.71)× 109·L-1 and(172.63±38.94)× 109·L-1,respectively;the positive rates of P-selectin(CD62P)were(24.58±5.34)％and(27.13±5.82)％;the positive rates of platelet activated complex-1(PAC-1)were(7.63±2.15)％and(8.45±2.69)％;serum endothelin-1(ET-1)levels were(61.03±5.97)and(65.39±7.14)ng·L-1,which were significantly reduced compared with those before treatment(all P＜0.05).The adverse drug reactions in treatment group were mainly headache,dyspnea and bleeding events,and the adverse drug reactions in control group were mainly dyspnea and bleeding events.The total incidence rates of adverse drug reactions in treatment group and control group were 11.22％(11 cases/98 cases)and 9.28％(9 cases/97 cases),respectively(P＞0.05).Conclusion Cilostazol combined with ticagrelor in patients with AMI after PCI is beneficial to inhibiting the platelet aggregation and activation,relieving the vascular endothelial function injury and reducing the risk of in-stent restenosis and MACE,and it has obvious advantages over aspirin combined with clopidogrel.

Objective To investigate the effect of pyrin domain 3 (NLRP3) inflammasome in the process of contrast induced human kidney cell apoptosis.Methods Human kidney 2 (HK-2) cells were cultured in DMEM-F12 medium with 5％ FBS.Cells were divided into control group,Contrast group (O group),NLRP3-siRNA+Iohexol group (si-NLRP3+O group),ASC-siRNA+Iohexol group (si-ASC+O group),and mannitol group (M group).Different concentrations of hypotonic contrast agent were added to HK-2 cell culture plates for 24,48 and 72 h.Flow cytometry was used to detect apoptosis.NLRP3 and ASC mRNA expressions were detected by RT-PCR.The expressions of NLRP3,ASC,caspase-8/cleaved caspase-8,Bcl-2/Bax,caspase-1/cleaved caspase-1,and caspase-3/cleaved caspase-3 protein were detected by Western blot.The levels of interleukin (IL) 1β and IL-18 in supernatant were detected by ELISA.Results Compared with the control group,the rate of apoptotic cells,as well as the expressions of NLRP3,ASC and cleaved caspase-1 proteins were increased in HK-2 cells of contrast group.The expressions of NLRP3 and ASC mRNA in the contrast group also increased,so did IL-1β and IL-18 levels (all P＜0.05),suggesting that NLRP3 inflammasome in HK-2 cells was activated by contrast.Compared with the control group,the expressions of cleaved caspase-8,Bax and cleaved caspase-3 protein were increased,and the expression of anti-apoptotic protein Bcl-2 was decreased (all P ＜ 0.05).Compared with the contrast group,the rate of apoptotic cells in the si-NLRP3 + contrast group and si-ASC + contrast group was significantly decreased;the expression of cleaved caspase-1 was decreased;the expressions of Bax and cleaved caspase-3 were decreased,and Bcl-2 level was increased.The expressions of IL-1β and IL-18 in the supernatant of cells were decreased (all P ＜ 0.05).Conclusion Contrast agent can activate the NLRP3 pathway in HK-2 cells and induce apoptosis,which could be reduced by blocking the NLRP3 pathway.

Heart failure(HF)is the end stage of almost all cardiovascular diseases,including coronary heart disease and structural heart disease.For end-stage HF,medications and cardiac assist devices have limited therapeutic effects,and heart transplantation is associated with donor shortage and immune rejection.Alginate hydrogel has the ability to mechanically support and induce cardiac tissue regeneration and repair.In March 2021,we conducted the world's first transcatheter endocardial alginate-hydrogel implantation in patients with end-stage heart failure,and explored the safety and feasibility of the treatment.Given that patients with heart failure who had undergone cardiac resynchronization therapy defibrillator(CRT-D)were excluded from previous studies,this paper is the first to report a case of transcatheter endocardial alginate-hydrogel implantation in a patient with heart failure who did not respond to CRT-D,with a significant reduction in the number of visits to the doctor and a significant improvement in the quality of life during the post-procedure follow-up,which may expand the indications for the use of this technology.

Objective To evaluate the efficacy of extracorporeal membrane oxygenation(ECMO)in patients with reduced left ventricular ejection fraction(LVEF)undergoing transcatheter aortic valve implantation(TAVR).Methods This was a single-center,retrospective study enrolling a total of 30 patients with reduced LVEF undergoing TAVR from January 2020 to January 2024.Of these,12 patients underwent TAVR with ECMO.Baseline clinical characteristics,preprocedural echocardiographic and computed tomographic(CT)measurements,TAVR procedural details,and follow-up data at 60-day and 6-month were collected.Results Among the 30 patients,there were 20 males with an average age of(67.0±10.4)years,an average STS score of(8.2±1.8)points,and an average LVEF of(21.2±5.3)％.This study included 11 AR patients,all of whom were in the group without ECMO implantation,and the difference between the two groups was statistically significant(P=0.027).During the operation,there were 0 cases of circulatory collapse in the ECMO group,and 5 cases(5/18)of circulatory collapse in the non ECMO group.All 5 patients underwent emergency ECMO placement.There were statistically significant differences(P＜0.05)in the comparison of two groups with circulatory collapse and salvage ECMO implantation.The technical success rate of 30 patients was 76.7％(23/30),and the instrument success rate was 60.0％(18/30).Among them,the technical success rate and instrument success rate of the ECMO group were higher than those of the non ECMO group,but the differences were not statistically significant(both P＞0.05).During a 30 day follow-up,there were 0 all-cause deaths in the ECMO group and 9 all-cause deaths(9/18)in the non ECMO group.Among them,7 cases(7/18)died from cardiovascular causes.The differences in all-cause and cardiovascular cause deaths between the two groups were statistically significant(both P＜0.05).During a 6-month follow-up,one patient with ECMO died due to extensive cerebral infarction.The all-cause mortality rate during the 6-month follow-up was 1/12(8.3％),while the all-cause mortality rate without ECMO was 9/18(5.0％).The difference between the two groups was statistically significant(P=0.024).The incidence of stroke with ECMO was 1/12(8.3％),while without ECMO it was 0.There was no statistically significant difference between the two groups(P=0.978).Conclusions In patients with reduced LVEF undergoing TAVR,periprocedural ECMO support does seem to improve patient outcome.

OBJECTIVETo investigate the potential value of combined examinations of peripheral blood smear, bone marrow smear, bone marrow biopsy, chromosome banding analysis and flow cytometry (FCM) in the diagnoisis of myelodysplastic syndromes.

METHODSA total of 105 MDS patients who were admitted in our hospital from May 2013 to May 2015 and were diagnosed as MDS according to the criteria formulated by WHO were enrolled in this study. The accordance rate of diagnosis by the double test (peripheral blood smear plus bone marrow smear), triple test (above mentioned 2 tests plus bone marrow biopsy), quadruple test (above 3 tests plus chromosome banding analysis), and quintuple test (above 4 plus FCM) was amalyzed and compared.

RESULTSAmong the 105 MDS patients, the diagnosis accordance rate was 70.48% for double tests, while 83.81%, 84.76% and 93.33% for triple, quadruple and quintuplet tests, respectively which were significantly higher than that for double tests (peripheral blood smear plus bone marrow smear) (P < 0.05).

CONCLUSIONThe combined examination of the 5 methods can improve the accuracy of MDS diagnosis.

OBJECTIVE： To estab lish the method for simultaneous determination of the contents of cyperotundone ， nootkatone，α-cyperone and aristolone in the volatile oil of Cyperus rotundus ，compare the content differences of 4 components in C. rotundus samples from different origins ，and to provide reference for germplasm screening ，development and utilization of the medicinal material. METHODS ：The volatile oil was extracted from 46 batches of C. rotundus from 12 origins. The contents of cypermenone，nootkatone，α-cyperone and aristolone in volatile oil were determined by HPLC. The determination was performed on Kromasil C 18 column with mobile phase consisted of methanol-water （68∶32，V/V）at the flow rate of 1.0 mL/min；the column temperature was 30 ℃；the detection wavelength was set at 242 nm；the sample size was 20 μL. Using the contents of above 4 components as evaluation indexes ，radar image analysis ，cluster thermal map analysis and principal component analysis were performed for comparing the quality of C. rotundus from different origins. RESULTS ：The results of content determination methodology investigation met relevant requirements ；the total contents of 4 components in volatile oil from C. rotundus from different origins ranged from 136.986 4 to 538.832 1 mg/g，of which the total content of samples from Yunnan was the highest （the average value was 476.059 2 mg/g）. Radar image analysis results showed that the whole contour in the 4 origins of Guangdong ， Jiangxi，Guangxi and Yunnan was large relatively and better balanced ，among which the samples from Yunnan had the largest overall contour and the best balance. The cluster thermal map analysis results showed that the samples from 12 origins could be grouped into 2 categories，the first category was from Hubei ，Jiangxi，Yunnan，Sichuan，Guangdong，Shandong，Henan and Shaanxi；the second category was from Guangxi ，Shanxi，Anhui and Hainan ；the quality of samples from the first category were better than that of samples from the second category. The principal component analysis results showed that the cumulative contribution rate of the first three principal components was 96.1％，and the samples from 12 origins were mainly clustered into two categories ，which was consistent with the results of cluster thermal map analysis. CONCLUSIONS ：Established HPLC method can be used for simultaneous determination of cypermenone ，nootkatone，α-cyperone and aristolone in volatile oil of C. rotundus from different origins. Among the samples from 12 origins，the quality of medicinal material from Yunnan is better.
