Objective To investigate the predictive value of serum uric acid(UA),homocysteine(Hcy)and the product index of UA and Hcy in patients with stable coronary artery disease(SCAD).Methods A total of 783 patients with suspected coronary heart disease were collected,all of whom underwent coronary angiography.Patients were divided into coronary heart disease(CHD)group and non-coronary heart disease(NCHD)group.The CHD group was further divided into low score group(≤35 points)and high score group(>35 points)according to Gensini scores.Baseline data,blood lipids,Hcy,UA,left ventricular function ultrasound indicators,and comorbidities were collected.Logistic regression analysis was used to evaluate the risk factors associated with the onset of SCAD and severe coronary artery disease,while the Receiver Operating Characteristic(ROC)curve was conducted to assess the predictive efficacy of the product index of UA and Hcy,and related risk factors,for SCAD onset and severe coronary artery disease.Results 1.In CHD group,UA,Hcy and the product index of UA and Hcy were all higher than in the NCHD group(P<0.001);the high-score group had higher UA,Hcy and the product index of UA and Hcy than the low Gensini score group(P<0.001).2.Multivariate logistic regression analysis showed that female age,sex,body mass index(BMI),product index of UA and Hcy,high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),left ventricular end-systolic volume(LVESV),left ventricular ejection fraction(LVEF),type 2 diabetes mellitus(T2DM)and hypertension(HTN)were independent risk factors for SCAD(P<0.05).BMI,the product index of UA and Hcy,HDL-C,LDL-C and LVEF were independent risk factors for severe coronary artery disease(P<0.05).3.There was a positive correlation between UA and Hcy product index and Gensini scores(r=0.433,P<0.05).4.Receiver operating characteristic curve analysis showed that the product index of UA and Hcy and combined detection of coronary heart disease risk factors had predictive value for the occurrence of SCAD(P<0.05),and the predictive value of combined detection was higher(area under the curve 0.808);both the product index of UA and Hcy and the combined detection of coronary heart disease risk factors had predictive value for severe coronary artery lesions(P<0.05),with a higher predictive value for combined detection(area under the curve 0.771).Conclusion As an independent predictor of the risk of SCAD and severe coronary stenosis,the product index of UA and Hcy has a high predictive efficacy regarding disease risk and the severity of coronary artery in patients with SCAD.

Objective To evaluate the predictive value of changes in serum homocysteine(Hcy),high-density lipoprotein cholesterol(HDL-C),and the homocysteine-to-HDL-C ratio(HHR)for the incidence and short-term prognosis of patients with premature coronary heart disease(PCHD).Methods Between January 2022 and December 2023,301 patients with the suspected coronary heart disease(males≤55 years,females≤65 years)were retrospectively selected from the Department of Cardiology at the Third People's Hospital of Yunnan Province.All patients who underwent coronary angiography(CAG)were divided into the premature coronary heart disease(PCHD)group(n=98)and the non-coronary heart disease(NCHD)group(n=203).Patients with PCHD were followed up six months after the discharge and were further classified into the good prognosis group(n=55)and the poor prognosis group(n=43)based on the presence of worsening clinical symptoms such as chest tightness,chest pain,arrhythmias,heart failure,or death.Data collected included general patient information,blood lipid levels,Hcy levels,left ventricular function ultrasound indicators,and the presence of hypertension and type 2 diabetes.Results Hcy and HHR levels were significantly higher in the PCHD group compared to the NCHD group,while HDL-C levels were lower(P<0.001).In the poor prognosis group,Hcy and HHR levels were elevated,and HDL-C levels were reduced compared to the good prognosis group(P<0.001).The Hcy and HHR levels in the severe coronary artery stenosis group were markedly higher than those in the normal coronary artery group and the mild to the moderate stenosis group,with HDL-C levels being lower(P<0.001).Multivariate logistic regression analysis identified that male sex,HHR,Hcy,low-density lipoprotein cholesterol(LDL-C),and left ventricular ejection fraction(LVEF)were independent factors influencing premature coronary heart disease(P<0.05).HHR was found to be an independent risk factor for the poor short-term prognosis in PCHD.The analysis of the operating characteristic curve of the subjects showed that serum Hcy and HHR had the predictive value for the occurrence of PCHD(P<0.05),with HHR showing higher predictive value(area under the curve[AUC]=0.713).HHR also had the substantial predictive value for the short-term prognosis of PCHD(AUC=0.715).Conclusion Elevated HHR levels are associated with the severe coronary artery disease in patients with PCHD.HHR serves as a significant predictor for both the occurrence and short-term prognosis of PCHD.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in healthcare facilities in major regions of China in 2023.Methods Clinical isolates collected from 73 hospitals across China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2023 Clinical & Laboratory Standards Institute (CLSI) breakpoints.Results A total of 445199 clinical isolates were collected in 2023,of which 29.0％ were gram-positive and 71.0％ were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species (excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi) (MRSA,MRSE and MRCNS) was 29.6％,81.9％ and 78.5％,respectively.Methicillin-resistant strains showed significantly higher resistance rates to most antimicrobial agents than methicillin-susceptible strains (MSSA,MSSE and MSCNS).Overall,92.9％ of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 91.4％ of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis had significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 93.1％ in the isolates from children and and 95.9％ in the isolates from adults.The resistance rate to carbapenems was lower than 15.0％ for most Enterobacterales species except for Klebsiella,22.5％ and 23.6％ of which were resistant to imipenem and meropenem,respectively .Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.6％ to 10.0％.The resistance rate to imipenem and meropenem was 21.9％ and 17.4％ for Pseudomonas aeruginosa,respectively,and 67.5％ and 68.1％ for Acinetobacter baumannii,respectively.Conclusions Increasing resistance to the commonly used antimicrobial agents is still observed in clinical bacterial isolates.However,the prevalence of important crabapenem-resistant organisms such as crabapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a slightly decreasing trend.This finding suggests that strengthening bacterial resistance surveillance and multidisciplinary linkage are important for preventing the occurrence and development of bacterial resistance.

Objective:To report for the first time the clinicopathologic characteristics of two patients with light chain deposition disease after renal transplantation.Methods:The clinicopathologic features were analyzed for two patients with light chain deposition disease and the related literature was reviewed.Case 1 was a 49-year-old male with unknown primary disease presenting with abnormal urine test and elevated serum creatinine at 24 months after kidney transplantation. Renal allograft biopsy hinted at light chain deposition disease. Case 2 was a 38-year-old male with light chain deposition disease in native kidneys presenting with proteinuria, microscopic hematuria and elevated serum creatinine at 15 months after kidney transplantation. Renal allograft biopsy supported recurrent light chain deposition disease.Results:1 case after bortezomib and dexamethasone dosing, serum creatinine decreased during follow-ups. 1 case received bortezomib and dexamethasone. However, sepsis and pulmonary infections developed and allograft function deteriorated.Conclusions:Light chain deposition disease after renal transplantation is a rare disorder with a rapid progression and a poor prognosis. Early detection of free light chain in blood and urine through immune fixed electrophoresis is conducive to an early diagnosis. The efficacy of bortezomib is to be furthered examined.

Objective: To explore the correlation of monocyte to HDL-C ratio (MHR) and post-operative slow lfow or no relfow in patients with ST-segment elevation myocardial infarction (STEMI) after percutaneous coronary intervention (PCI). Methods: A total of 216 STEMI patients treated in our hospital from 2014-10 to 2016-05 were enrolled. The patients were divided into 2 groups: Slow lfow or no relfow group, the patients with TIMI grade≤2,n=43 and Normal lfow group, n=173. Receiver operating characteristic (ROC) curve was performed to assess the best cut-off value for MHR predicting slow lfow or no relfow with its sensitivity and speciifcity; Logistic regression analysis was conducted to studied weather MHR could be used as an independent risk factor for coronary slow lfow or no relfow in STEMI patients after PCI. Results: Compared with Normal lfow group, Slow lfow or no relfow group had the higher MHR (18.6±9.8) vs (10.9±5.5), P<0.001. Univariate Regression analysis indicated that MHR was a risk factor of slow lfow or no relfow occurrence (OR=2.22, 95% CI 1.58-3.28); multivariate regression analysis presented that MHR was an independent risk factor of slow lfow or no relfow occurrence (OR=1.55, 95% CI 1.01-2.38). ROC curve showed that the best cut-off value for MHR predicting slow lfow or no relfow occurrence was 13.37 with the sensitivity and speciifcity at 67.4% and 70.5% respectively, the area under curve (AUC) was 0.734, 95% CI 0.646-0.822. Conclusion: MHR was an independent risk factor for slow lfow or no relfow occurrence in STEMI patients after PCI.

Objective To investigate the safety and efficacy of mechanical thrombectomy (MT) compared with In?tra-arterial Thrombolysis (IAT) treatment in patients with severe acute ischemic stroke (AIS) caused by large cerebral ar?tery occlusion. Method The patients with AIS caused by large cerebral artery occlusion and underwent MT or IAT from 2005 May to 2014 May was included. A retrospective analysis was conducted on the onset to emergency(OTE)time, emergency to acupuncture(ETA)time, acupuncture to recanalization (ATR) time, stroke severity as measured by the Na?tional Institutes of Health Stroke Scale (NIHSS) score, and site of arterial occlusion on magnetic resonance angiography (MRA). A comparison was made between MT and IAT patients in rates of recanalization, symptomatic intracranial bleed?ing (SIB), mortality, and functional outcome. Three-month favourable outcome was defined as a modified Rankin Scale (mRS) score≤2. Result One hundred and two AIS patients were treated with MT and 50 with IAT. There was no differ?ence between MT and IAT groups with regard to demographics, onset NIHSS score (13.37±6.95 vs. 12.70±6.11;P=0.572) and discharge NIHSS score (8.40 ± 6.69 vs. 7.53 ± 7.28, P= 0.522) and the change of NIHSS score (3.87 ± 7.14 vs. 4.26 ± 5.42, P=0.766). There were significantly differences between MT and IAT groups in the OTE time (Median 300 min vs. 120 min,Z=-5.704,P=0.000) , ATR time (Median 30 min vs. 65 min,Z=-5.011,P=0.001) ,recanalization (91.2%vs. 60.0%,P =0.01),the rate of AIB(21.7% vs. 36.0%,P =0.046),3-month mortality (16.6% vs. 26.0%,P =0.043). The above parameters were better in MT group than in the IAT group. There were no significant differences between MT and IAT groups in the rate of SIB (12% vs. 16%,P =0.055), the NIHSS change(Median 3 vs. 4,Z =-0.236,P =0.823) and mRS score on 90d ( 48.2%vs. 46.0%, P=0.823). MT patients had significantly higher percentages of stent use (22.5%vs. 8%,P=0.018) . The Recanalization for ICA(81.8%vs. 55.6%,P=0.048),BA(93.1%vs. 55.6%,P=0.032)and MCA( 97.5% vs. 60.0%,P =0.026)was higher in MT group than in IAT group .The SIB rate for ICA(13.8% vs. 33.3%,P =0.000),BA(13.8%vs. 33.3%,P=0.000)was lower in MT group than in IAT group . The mortality rate of was significant?ly lower in MT than in IAT group for MCA (2.5%vs. 20.0%,P=0.000) . the good outcome rate for BA was higher in MT group than in IAT group(41.3%vs. 22.2%,P﹤0.01). Conclusions Compared to IAT,MT can provide broader time win?dow,higher recanalization rate and better outcome in patients with severe acute ischemic stroke (AIS) caused by large ce?rebral artery occlusion.

White matter lesions on neuroimaging are common in the normal aged and in patients with several cognitive disorders. Its pathological features include demyelination, axonal loss and lacunar infarction, and the pathophysiological mechanisms may be chronic cerebral ischemia caused by hypoperfusion and disturbance of cerebral blood flow disorders. Vascular white matter lesiom may cause different degrees of cogntive disorders, but the exact the pathological subtype of dementia associated with white matter lesions remains uncertain.

OBJECTIVE: To explore the composition characteristics of traditional Chinese medicine (TCM) syndromes in patients with acute ischemic stroke of yin or yang syndrome by investigating the characteristics of TCM syndromes at different periods after onset. METHODS: One thousand two hundred and forty-six patients with acute ischemic stroke were admitted in twenty hospitals. According to the "diagnostic criteria of syndrome differentiation of stroke", the characteristics of syndromes in the patients were investigated at the periods of 1-3 days, 4-10 days and 11-30 days after they had ischemic stroke. General distribution of six basic syndromes was compared between the patients with yin syndrome and the patients with yang syndrome at the three periods. The six basic syndromes were wind syndrome, pathogenic fire syndrome, phlegm syndrome, blood stasis syndrome, qi deficiency syndrome, and syndrome of yin deficiency and yang hyperactivity. RESULTS: The percentages of wind, pathogenic fire, and phlegm syndromes in the patients were decreased at the period of 11-30 days as compared with the period of 1-3 days (87.1% vs 79.3%, 52.1% vs 38.7% and 67.1% vs 57.4% respectively, P<0.01). However, the percentages of the syndromes of blood stasis, qi deficiency, and yin deficiency and yang hyperactivity were similar at the three periods (P>0.05). There were no differences in the distribution of yin and yang syndromes among the three periods (P>0.05). The percentages of syndromes of wind, pathogenic fire, phlegm, and yin deficiency and yang hyperactivity were higher (P<0.01), and the percentages of syndromes of blood stasis and qi deficiency were lower (P<0.05, P<0.01) in patients with yang syndrome than in patients with yin syndrome. The complex of three syndromes was the most frequent composition pattern in the patients at the three periods. The percentages of complex syndromes of four or five syndromes were higher, and the percentages of single-syndromes and complex syndromes of two syndromes were lower in patients with yang syndrome than in patients with yin syndrome (P<0.05, P<0.01). The most frequent complex syndromes in patients with yin syndrome were complex syndrome of wind, phlegm, blood stasis and qi deficiency, and complex syndrome of wind, phlegm and qi deficiency; while the most frequent complex syndromes in patients with yang syndrome were complex syndrome of wind, pathogenic fire, phlegm and qi deficiency, and complex syndrome of wind, pathogenic fire and phlegm. CONCLUSION: The main discrimination between the yin and yang syndromes is that the yang syndrome is characterized by pathogenic fire. The syndromes of phlegm, qi deficiency, and blood stasis are not associated with the diagnosis of yin or yang syndrome.

0.05).In the 35 patient who had unitary incontinence before the operation,the symptom disappeared in 6(17.1%) patients,and deteriorated in 2(5.7%).While in the 38 patients without urinary incontinence before the operation,9(23.7%) showed the symptom postoperation.Totally,urinary incontinence was developed in 11 patients after the operation.Conclusions The patients with moderate-to-severe pelvic organ prolapse treated by traditional surgical procedures have a low rate of objective cure and a high rate of recurrent cystocele.It is important to repair the anterior pelvic floor during the operation.And the surgeons should be alert to the possibility of urinary incontinence.
